    Radiotherapy is the main treatment modality for uterine cervix cancer. Since the rectum is in the radiation target volume, rectal bleeding is a common late side effect. The study evaluates the risk factors of radiation induced rectal bleeding and discusses its optimal management. A total of 213 patients who completed external beam radiation therapy (EBRT) and intracavitary radiation (ICR) between September 1994 and December 1999 were included in this study. No patient had undergone concurrent chemo-radiotherapy. Ninety patients received radiotherapy according to a modified hyperfractionated schedule. A midline block was placed at a pelvic dose of between 30.6 Gy to 39.6 Gy. The total parametrial dose from the EBRT was 51 to 59 Gy depending on the extent of their disease. The point A dose from the HDR brachytherapy was 28 Gy to 30 Gy (4 Gy x 7, or 5 Gy x 6). The rectal point dose was calculated either by the ICRU 38 guideline, or by anterior rectal wall point seen on radiographs, with barium contrast. Rectal bleeding was scored by the LENT/SOMA criteria. For the management of rectal bleeding, we opted for observation, sucralfate enema or coagulation based on the frequency or amount of bleeding. The median follow-up period was 39 months (12 {approx} 86 months). The incidence of rectal bleeding was 12.7% (27/213); graded as 1 in 9 patients, grade 2 in 16 and grade 3 in 2. The overall moderate and severe rectal complication rate was 8.5%. Most complications (92.6%) developed within 2 years following completion of radiotherapy (median 16 months). No patient progressed to rectal fistula or obstruction during the follow-up period. In the univariate analysis, three factors correlated with a high incidence of bleeding: an icruCRBED greater than 100 Gy (19.7% vs. 4.2%), an EBRT dose to the parametrium over 55 Gy (22.1% vs. 5.1%) and higher stages of III and IV (31.8% vs. 10.5%). In the multivariate analysis, the icruCRBED was the only significant factor ({rho} > 0.0432). The

    Temiz, Abdulkerim; Tander, Burak; Temiz, Muhyittin; Barış, Sancar; Arıtürk, Ender


    Solitary rectal ulcer causing lower gastrointestinal bleeding is extremely rare in children. Rare presentation, non-specific symptoms, insufficient experience, and characteristics mimicking other rectal diseases may cause misdiagnosis or delay of diagnosis in some pediatric patients. Here, we report a 10-year-old boy with solitary rectal ulcer diagnosed two years after onset of the symptoms who responded well to the conservative therapy, including high-fiber diet, laxatives, defecation training, and sucralfate enema.

    Objective:To emphasize the value of emergency diagnostic angiography and angioembolization in massive postoperative bleeding. Methods:A case report was presented and electronic search of U.S. National Library of Medicine National Institutes of Health PubMed/MEDLINE, EMBASE, Google Scholar, ISI Web of Knowledge, to identify original articles and reviews about the subject. Results: A 55 year-old male patient was addmited for rectal bleeding. ECOG index=2, digital rectal examination revealed the inferior pole of a middle rectal tumor. Colonoscopy exam validated the presence of a middle rectal tumor, 8 cm from the anal verge. CT scan showed rectal wall thickening up to 3 cm, that extends 9 cm proximally, whit infiltration of the perirectal fatty tissue and multiple enlarged lymph nodes up to 12 mm in dimension. There was a laparoscopic converted to open approach, with low anterior resection of the rectum and total mesorectal excision, an end to end stapled colorectal anastomosis and protective loop ileostomy. In the 5th postoperative day a massive lower gastrointestinal bleeding occured, with hypovolemic shock and a decrease in hemoglobin. Emergency angiography was performed. This revealed active bleeding from an internal iliac branch that was successfully angioembolized. Conclusions: Angiography with angioembolization is an effective tool in emergency setting, avoiding the morbidity and associated mortality of a surgical reinervention. In early postoperative hemorrhages, only a rapid clinical recognition, a personalized diagnostic workup and an agressive intervention may offer the patient the best chances for cure.

  6. Massive rectal bleeding from acquired jejunal diverticula


    Abstract Small bowel diverticulosis is an uncommon and often asymptomatic condition that is sporadically observed during radiographic examination or laparotomy. Although it is frequently seen in duodenum, jejunal and ileal locations are very rare. The majority of patients with jejunal diverticula have no symptoms. However, they can present with a number of acute and emergent complications with a high rate of mortality. Bleeding from jejunal diverticula occurs in less than 3% - 8% of patients ...

    Casal Núñez, Jose Enrique; Vigorita, Vincenzo; Ruano Poblador, Alejandro; Gay Fernández, Ana María; Toscano Novella, Maria Ángeles; Cáceres Alvarado, Nieves; Pérez Dominguez, Lucinda


    AIM To analyze the anatomy of sacral venous plexus flow, the causes of injuries and the methods for controlling presacral hemorrhage during surgery for rectal cancer. METHODS A review of the databases MEDLINE® and Embase™ was conducted, and relevant scientific articles published between January 1960 and June 2016 were examined. The anatomy of the sacrum and its venous plexus, as well as the factors that influence bleeding, the causes of this complication, and its surgical management were defined. RESULTS This is a review of 58 published articles on presacral venous plexus injury during the mobilization of the rectum and on techniques used to treat presacral venous bleeding. Due to the lack of cases published in the literature, there is no consensus on which is the best technique to use if there is presacral bleeding during mobilization in surgery for rectal cancer. This review may provide a tool to help surgeons make decisions regarding how to resolve this serious complication. CONCLUSION A series of alternative treatments are described; however, a conventional systematic review in which optimal treatment is identified could not be performed because few cases were analyzed in most publications.

  8. Argon Plasma Coagulation Therapy Versus Topical Formalin for Intractable Rectal Bleeding and Anorectal Dysfunction After Radiation Therapy for Prostate Carcinoma

    Yeoh, Eric, E-mail: [Department of Radiation Oncology, Royal Adelaide Hospital, Adelaide (Australia); School of Medicine, University of Adelaide, Adelaide (Australia); Tam, William; Schoeman, Mark [School of Medicine, University of Adelaide, Adelaide (Australia); Department of Gastroenterology, Royal Adelaide Hospital, Adelaide (Australia); Moore, James; Thomas, Michelle [School of Medicine, University of Adelaide, Adelaide (Australia); Department of Colorectal Surgery, Royal Adelaide Hospital, Adelaide (Australia); Botten, Rochelle; Di Matteo, Addolorata [Department of Radiation Oncology, Royal Adelaide Hospital, Adelaide (Australia)


    Purpose: To evaluate and compare the effect of argon plasma coagulation (APC) and topical formalin for intractable rectal bleeding and anorectal dysfunction associated with chronic radiation proctitis. Methods and Materials: Thirty men (median age, 72 years; range, 49-87 years) with intractable rectal bleeding (defined as ≥1× per week and/or requiring blood transfusions) after radiation therapy for prostate carcinoma were randomized to treatment with APC (n=17) or topical formalin (n=13). Each patient underwent evaluations of (1) anorectal symptoms (validated questionnaires, including modified Late Effects in Normal Tissues–Subjective, Objective, Management, and Analytic and visual analogue scales for rectal bleeding); (2) anorectal motor and sensory function (manometry and graded rectal balloon distension); and (3) anal sphincteric morphology (endoanal ultrasound) before and after the treatment endpoint (defined as reduction in rectal bleeding to 1× per month or better, reduction in visual analogue scales to ≤25 mm, and no longer needing blood transfusions). Results: The treatment endpoint was achieved in 94% of the APC group and 100% of the topical formalin group after a median (range) of 2 (1-5) sessions of either treatment. After a follow-up duration of 111 (29-170) months, only 1 patient in each group needed further treatment. Reductions in rectal compliance and volumes of sensory perception occurred after APC, but no effect on anorectal symptoms other than rectal bleeding was observed. There were no differences between APC and topical formalin for anorectal symptoms and function, nor for anal sphincteric morphology. Conclusions: Argon plasma coagulation and topical formalin had comparable efficacy in the durable control of rectal bleeding associated with chronic radiation proctitis but had no beneficial effect on anorectal dysfunction.

    Rectal bleeding is frequently seen in patients undergoing transrectal ultrasound (TRUS)-guided multiple biopsy of the prostate, but is usually mild and stops spontaneously. We report what is believed to be the first case of life-threatening rectal bleeding following this procedure, which was successfully treated by endoscopic intervention through placement of three clips on the sites of bleeding. This case emphasizes endoscopic intervention associated with endoclipping as a safe and effective method to achieve hemostasis in massive rectal bleeding after prostate biopsy. Additionally, current data on the complications of the TRUS-guided multiple biopsy of the prostate and the options for treating fulminant rectal bleeding, a consequence of this procedure, are described.

  12. Ozone Therapy in the Management of Persistent Radiation-Induced Rectal Bleeding in Prostate Cancer Patients

    Bernardino Clavo


    Full Text Available Introduction. Persistent radiation-induced proctitis and rectal bleeding are debilitating complications with limited therapeutic options. We present our experience with ozone therapy in the management of such refractory rectal bleeding. Methods. Patients (n=12 previously irradiated for prostate cancer with persistent or severe rectal bleeding without response to conventional treatment were enrolled to receive ozone therapy via rectal insufflations and/or topical application of ozonized-oil. Ten (83% patients had Grade 3 or Grade 4 toxicity. Median follow-up after ozone therapy was 104 months (range: 52–119. Results. Following ozone therapy, the median grade of toxicity improved from 3 to 1 (p<0.001 and the number of endoscopy treatments from 37 to 4 (p=0.032. Hemoglobin levels changed from 11.1 (7–14 g/dL to 13 (10–15 g/dL, before and after ozone therapy, respectively (p=0.008. Ozone therapy was well tolerated and no adverse effects were noted, except soft and temporary flatulence for some hours after each session. Conclusions. Ozone therapy was effective in radiation-induced rectal bleeding in prostate cancer patients without serious adverse events. It proved useful in the management of rectal bleeding and merits further evaluation.

  13. Predictive Factors and Management of Rectal Bleeding Side Effects Following Prostate Cancer Brachytherapy

    Price, Jeremy G. [Department of Radiation Oncology, Icahn School of Medicine at Mount Sinai, New York, New York (United States); Stone, Nelson N. [Department of Urology, Icahn School of Medicine at Mount Sinai, New York, New York (United States); Stock, Richard G., E-mail: [Department of Radiation Oncology, Icahn School of Medicine at Mount Sinai, New York, New York (United States)


    Purpose: To report on the incidence, nature, and management of rectal toxicities following individual or combination brachytherapy following treatment for prostate cancer over a 17-year period. We also report the patient and treatment factors predisposing to acute ≥grade 2 proctitis. Methods and Materials: A total of 2752 patients were treated for prostate cancer between October 1990 and April 2007 with either low-dose-rate brachytherapy alone or in combination with androgen depletion therapy (ADT) or external beam radiation therapy (EBRT) and were followed for a median of 5.86 years (minimum 1.0 years; maximum 19.19 years). We investigated the 10-year incidence, nature, and treatment of acute and chronic rectal toxicities following BT. Using univariate, and multivariate analyses, we determined the treatment and comorbidity factors predisposing to rectal toxicities. We also outline the most common and effective management for these toxicities. Results: Actuarial risk of ≥grade 2 rectal bleeding was 6.4%, though notably only 0.9% of all patients required medical intervention to manage this toxicity. The majority of rectal bleeding episodes (72%) occurred within the first 3 years following placement of BT seeds. Of the 27 patients requiring management for their rectal bleeding, 18 underwent formalin treatment and nine underwent cauterization. Post-hoc univariate statistical analysis revealed that coronary artery disease (CAD), biologically effective dose, rectal volume receiving 100% of the prescription dose (RV100), and treatment modality predict the likelihood of grade ≥2 rectal bleeding. Only CAD, treatment type, and RV100 fit a Cox regression multivariate model. Conclusions: Low-dose-rate prostate brachytherapy is very well tolerated and rectal bleeding toxicities are either self-resolving or effectively managed by medical intervention. Treatment planning incorporating adjuvant ADT while minimizing RV100 has yielded the best toxicity-free survival following

  14. Using dose-surface maps to predict radiation-induced rectal bleeding: a neural network approach.

    Buettner, Florian; Gulliford, Sarah L; Webb, Steve; Partridge, Mike


    The incidence of late-toxicities after radiotherapy can be modelled based on the dose delivered to the organ under consideration. Most predictive models reduce the dose distribution to a set of dose-volume parameters and do not take the spatial distribution of the dose into account. The aim of this study was to develop a classifier predicting radiation-induced rectal bleeding using all available information on the dose to the rectal wall. The dose was projected on a two-dimensional dose-surface map (DSM) by virtual rectum-unfolding. These DSMs were used as inputs for a classification method based on locally connected neural networks. In contrast to fully connected conventional neural nets, locally connected nets take the topology of the input into account. In order to train the nets, data from 329 patients from the RT01 trial (ISRCTN 47772397) were split into ten roughly equal parts. By using nine of these parts as a training set and the remaining part as an independent test set, a ten-fold cross-validation was performed. Ensemble learning was used and 250 nets were built from randomly selected patients from the training set. Out of these 250 nets, an ensemble of expert nets was chosen. The performances of the full ensemble and of the expert ensemble were quantified by using receiver-operator-characteristic (ROC) curves. In order to quantify the predictive power of the shape, ensembles of fully connected conventional neural nets based on dose-surface histograms (DSHs) were generated and their performances were quantified. The expert ensembles performed better than or equally as well as the full ensembles. The area under the ROC curve for the DSM-based expert ensemble was 0.64. The area under the ROC curve for the DSH-based expert ensemble equalled 0.59. This difference in performance indicates that not only volumetric, but also morphological aspects of the dose distribution are correlated to rectal bleeding after radiotherapy. Thus, the shape of the dose

    AIM: To investigate potential roles of per rectal portal scintigraphy in diagnosis of esophageal varices and predicting the risk of bleeding.METHODS: Fifteen normal subjects and fifty cirrhotic patients with endoscopically confirmed esophageal varices were included. Patients were categorized into bleeder and non-bleeder groups according to history of variceal bleeding. All had completed per rectal portal scintigraphy using 99mTechnetium pertechnetate.The shunt index was calculated from the ratio of 99mTechnetium pertechnetate in the heart and the liver.Data were analyzed using Student's t-test and receiver operating characteristics.RESULTS: Cirrhotic patients showed a higher shunt index than normal subjects (63.80 ± 25.21 vs 13.54 ± 6.46, P < 0.01). Patients with variceal bleeding showed a higher shunt index than those without bleeding (78.45 ± 9.40 vs 49.35 ± 27.72, P < 0.01). A shunt index of over 20% indicated the presence of varices and that of over 60% indicated the risk of variceal bleeding.CONCLUSION: In cirrhotic patients, per rectal portal scintigraphy is a clinically useful test for identifying esophageal varices and risk of variceal bleeding.

    C Fotiadis; M Genetzakis; I Papandreou; EP Misiakos; E Agapitos; GC Zografos


    Gastrointestinal duplication is an uncommon congenital abnormality in two-thirds of cases manifesting before the age of 2 years. Ileal duplication is common while colonic duplication, either cystic or tubular, is a rather unusual clinical entity that remains asymptomatic and undiagnosed in most cases. Mostly occurring in pediatric patients,colonic duplication is encountered in adults only in a few cases. This study reports two cases of colonic duplication in adults. Both cases presented with rectal bleeding on admission. The study was focused on clinical, imaging,histological, and therapeutical aspects of the presenting cases. Gastrografin enema established the diagnosis in both cases. The cystic structure and the adjacent part of the colon were excised en-block. The study implies that colonic duplication, though uncommon, should be included in the differential diagnosis of rectal bleeding.

  17. Traumatic pseudoaneurysm of the superior rectal artery with recurrent lower gastrointestinal and pelvic extraperitoneal bleeding: Importance of pretreatment recognition

    Kim, Kyung Joon; Seo, Jung Wook; Kim, You Sung [Dept. of Radiology, Ilsan Paik Hospital, Inje University College of Medicine, Goyang (Korea, Republic of)


    Traumatic pseudoaneurysm of the superior rectal artery is a rare cause of massive lower gastrointestinal bleeding. We reported a case of a 43-year-old male patient with pseudoaneurysm following a penetrating perineal wound. The patient had repeat massive lower gastrointestinal and pelvic extraperitoneal bleeding and was diagnosed as traumatic pseudoaneurysm of the superior rectal artery. To our knowledge, there are three case reports of traumatic pseudoaneurysm of the superior rectal artery treated by embolization. However, spontaneous regression occurred in the study subject after surgical hematoma removal, without any further pseudoaneurysm resection.

  18. Novel Parameter Predicting Grade 2 Rectal Bleeding After Iodine-125 Prostate Brachytherapy Combined With External Beam Radiation Therapy

    Shiraishi, Yutaka, E-mail: [Department of Radiology, Keio University School of Medicine, Tokyo (Japan); Hanada, Takashi; Ohashi, Toshio [Department of Radiology, Keio University School of Medicine, Tokyo (Japan); Yorozu, Atsunori; Toya, Kazuhito [Department of Radiology, National Hospital Organization Tokyo Medical Center, Tokyo (Japan); Saito, Shiro [Department of Urology, National Hospital Organization Tokyo Medical Center, Tokyo (Japan); Shigematsu, Naoyuki [Department of Radiology, Keio University School of Medicine, Tokyo (Japan)


    Purpose: To propose a novel parameter predicting rectal bleeding on the basis of generalized equivalent uniform doses (gEUD) after {sup 125}I prostate brachytherapy combined with external beam radiation therapy and to assess the predictive value of this parameter. Methods and Materials: To account for differences among radiation treatment modalities and fractionation schedules, rectal dose–volume histograms (DVHs) of 369 patients with localized prostate cancer undergoing combined therapy retrieved from corresponding treatment planning systems were converted to equivalent dose-based DVHs. The gEUDs for the rectum were calculated from these converted DVHs. The total gEUD (gEUD{sub sum}) was determined by a summation of the brachytherapy and external-beam radiation therapy components. Results: Thirty-eight patients (10.3%) developed grade 2+ rectal bleeding. The grade 2+ rectal bleeding rate increased as the gEUD{sub sum} increased: 2.0% (2 of 102 patients) for <70 Gy, 10.3% (15 of 145 patients) for 70-80 Gy, 15.8% (12 of 76 patients) for 80-90 Gy, and 19.6% (9 of 46 patients) for >90 Gy (P=.002). Multivariate analysis identified age (P=.024) and gEUD{sub sum} (P=.000) as risk factors for grade 2+ rectal bleeding. Conclusions: Our results demonstrate gEUD to be a potential predictive factor for grade 2+ late rectal bleeding after combined therapy for prostate cancer.

  19. An Unusual Case of Appendiceal Adenocarcinoma Presenting with Rectal Bleeding and Haematuria

    John A. Murphy


    Full Text Available Adenocarcinoma of the appendix is rare, usually being diagnosed intraoperatively when performing appendicectomy or at subsequent histological examination. Here we report a case with acute abdominal pain, rectal bleeding with haematuria being the presenting symptoms. Subsequent computerised tomography demonstrated a complex mass involving the ileum, right colon, sigmoid colon and bladder with inflammatory bowel disease being the most likely cause. At laparotomy a right hemicolectomy, sigmoid colectomy and partial cystectomy was performed with pathological specimens confirming an appendiceal adenocarcinoma as the primary source of the abdominal mass fistulating into adjacent structures. We conclude that although appendiceal tumours are rare – usually diagnosed at appendicectomy, they should be considered in the diagnosis of complex abdominal masses involving small bowel, large bowel and adjacent pelvic structures.

  20. Self-assessed bowel toxicity after external beam radiotherapy for prostate cancer - predictive factors on irritative symptoms, incontinence and rectal bleeding

    Klotz Jens


    Full Text Available Abstract Background The aim of the study was to evaluate self-assessed bowel toxicity after radiotherapy (RT for prostate cancer. In contrast to rectal bleeding, information concerning irritative symptoms (rectal urgency, pain and incontinence after RT has not been adequately documented and reported in the past. Methods Patients (n = 286 have been surveyed prospectively before (A, at the last day (70.2-72.0 Gy; B, a median time of two (C and 16 months after RT (D using a validated questionnaire (Expanded Prostate Cancer Index Composite. Bowel domain score changes were analyzed and patient-/dose-volume-related factors tested for a predictive value on three separate factors (subscales: irritative symptoms, incontinence and rectal bleeding. Results Irritative symptoms were most strongly affected in the acute phase, but the scores of all subscales remained slightly lower at time D in comparison to baseline scores. Good correlations (correlation indices >0.4; p Conclusion PTV and specific comorbidities are important predictive factors on adverse bowel quality of life changes after RT for prostate cancer. However, greater rectum volumes inside high isodose levels have not been found to be associated with lower quality of life scores.

  1. SU-D-204-06: Integration of Machine Learning and Bioinformatics Methods to Analyze Genome-Wide Association Study Data for Rectal Bleeding and Erectile Dysfunction Following Radiotherapy in Prostate Cancer

    Oh, J; Deasy, J [Memorial Sloan Kettering Cancer Center, New York, NY (United States); Kerns, S [University of Rochester Medical Center, Rochester, NY (United States); Ostrer, H [Albert Einstein College of Medicine, Bronx, NY (United States); Rosenstein, B [Mount Sinai School of Medicine, New York, NY (United States)


    Purpose: We investigated whether integration of machine learning and bioinformatics techniques on genome-wide association study (GWAS) data can improve the performance of predictive models in predicting the risk of developing radiation-induced late rectal bleeding and erectile dysfunction in prostate cancer patients. Methods: We analyzed a GWAS dataset generated from 385 prostate cancer patients treated with radiotherapy. Using genotype information from these patients, we designed a machine learning-based predictive model of late radiation-induced toxicities: rectal bleeding and erectile dysfunction. The model building process was performed using 2/3 of samples (training) and the predictive model was tested with 1/3 of samples (validation). To identify important single nucleotide polymorphisms (SNPs), we computed the SNP importance score, resulting from our random forest regression model. We performed gene ontology (GO) enrichment analysis for nearby genes of the important SNPs. Results: After univariate analysis on the training dataset, we filtered out many SNPs with p>0.001, resulting in 749 and 367 SNPs that were used in the model building process for rectal bleeding and erectile dysfunction, respectively. On the validation dataset, our random forest regression model achieved the area under the curve (AUC)=0.70 and 0.62 for rectal bleeding and erectile dysfunction, respectively. We performed GO enrichment analysis for the top 25%, 50%, 75%, and 100% SNPs out of the select SNPs in the univariate analysis. When we used the top 50% SNPs, more plausible biological processes were obtained for both toxicities. An additional test with the top 50% SNPs improved predictive power with AUC=0.71 and 0.65 for rectal bleeding and erectile dysfunction. A better performance was achieved with AUC=0.67 when age and androgen deprivation therapy were added to the model for erectile dysfunction. Conclusion: Our approach that combines machine learning and bioinformatics techniques

  2. Knowledge of cancer symptoms among patients attending one-stop breast and rectal bleeding clinics.

    Pullyblank, A M; Cawthorn, S J; Dixon, A R


    The aim of this questionnaire study was to identify knowledge of breast and colorectal cancer symptoms among 100 patients attending one-stop breast clinics and rectal bleeding clinics and to determine the source of the information. Seventy-five breast clinic (mean age 46 years, all female) and 78 colorectal clinic patients (mean age 59 years, 51% male) responded. Knowledge of breast was significantly greater than bowel cancer in both groups (Pknowledge of symptoms of breast cancer or bowel cancer between patients attending either clinic. There was a positive association between cancer knowledge, family history and female gender but no association with age. Knowledge of Bowel Cancer Awareness Week was positively associated with colorectal cancer knowledge. Knowledge of colorectal cancer is much less than breast cancer in clinic attenders. Seventy-five per cent of women attending breast clinic could name a breast cancer symptom whereas only 37% of patients attending colorectal clinic could name a bowel cancer symptom. These findings have implications when considering patients' anxiety, expectations of a cancer diagnosis and breaking bad news.

  4. Treatment and prognosis of patients with late rectal bleeding after intensity-modulated radiation therapy for prostate cancer

    Takemoto Shinya


    Full Text Available Abstract Background Radiation proctitis after intensity-modulated radiation therapy (IMRT differs from that seen after pelvic irradiation in that this adverse event is a result of high-dose radiation to a very small area in the rectum. We evaluated the results of treatment for hemorrhagic proctitis after IMRT for prostate cancer. Methods Between November 2004 and February 2010, 403 patients with prostate cancer were treated with IMRT at 2 institutions. Among these patients, 64 patients who developed late rectal bleeding were evaluated. Forty patients had received IMRT using a linear accelerator and 24 by tomotherapy. Their median age was 72 years. Each patient was assessed clinically and/or endoscopically. Depending on the severity, steroid suppositories or enemas were administered up to twice daily and Argon plasma coagulation (APC was performed up to 3 times. Response to treatment was evaluated using the Rectal Bleeding Score (RBS, which is the sum of Frequency Score (graded from 1 to 3 by frequency of bleeding and Amount Score (graded from 1 to 3 by amount of bleeding. Stoppage of bleeding over 3 months was scored as RBS 1. Results The median follow-up period for treatment of rectal bleeding was 35 months (range, 12–69 months. Grade of bleeding was 1 in 31 patients, 2 in 26, and 3 in 7. Nineteen of 45 patients (42% observed without treatment showed improvement and bleeding stopped in 17 (38%, although mean RBS did not change significantly. Eighteen of 29 patients (62% treated with steroid suppositories or enemas showed improvement (mean RBS, from 4.1 ± 1.0 to 3.0 ± 1.8, p = 0.003 and bleeding stopped in 9 (31%. One patient treated with steroid enema 0.5-2 times a day for 12 months developed septic shock and died of multiple organ failure. All 12 patients treated with APC showed improvement (mean RBS, 4.7 ± 1.2 to 2.3 ± 1.4, p  Conclusions After adequate periods of observation, steroid suppositories

  5. Normal Tissue Complication Probability (NTCP) modeling of late rectal bleeding following external beam radiotherapy for prostate cancer: A Test of the QUANTEC-recommended NTCP model

(Dept. of Radiation Oncology and the Mallinckrodt Inst. of Radiology, Washington Univ., St. Louis, MO (United States)), e-mail:


    Purpose/background. Validating a predictive model for late rectal bleeding following external beam treatment for prostate cancer would enable safer treatments or dose escalation. We tested the normal tissue complication probability (NTCP) model recommended in the recent QUANTEC review (quantitative analysis of normal tissue effects in the clinic). Material and methods. One hundred and sixty one prostate cancer patients were treated with 3D conformal radiotherapy for prostate cancer at the British Columbia Cancer Agency in a prospective protocol. The total prescription dose for all patients was 74 Gy, delivered in 2 Gy/fraction. 159 3D treatment planning datasets were available for analysis. Rectal dose volume histograms were extracted and fitted to a Lyman-Kutcher-Burman NTCP model. Results. Late rectal bleeding (>grade 2) was observed in 12/159 patients (7.5%). Multivariate logistic regression with dose-volume parameters (V50, V60, V70, etc.) was non-significant. Among clinical variables, only age was significant on a Kaplan-Meier log-rank test (p=0.007, with an optimal cut point of 77 years). Best-fit Lyman-Kutcher-Burman model parameters (with 95% confidence intervals) were: n = 0.068 (0.01, +infinity); m =0.14 (0.0, 0.86); and TD50 81 (27, 136) Gy. The peak values fall within the 95% QUANTEC confidence intervals. On this dataset, both models had only modest ability to predict complications: the best-fit model had a Spearman's rank correlation coefficient of rs = 0.099 (p = 0.11) and area under the receiver operating characteristic curve (AUC) of 0.62; the QUANTEC model had rs=0.096 (p= 0.11) and a corresponding AUC of 0.61. Although the QUANTEC model consistently predicted higher NTCP values, it could not be rejected according to the chi2 test (p = 0.44). Conclusions. Observed complications, and best-fit parameter estimates, were consistent with the QUANTEC-preferred NTCP model. However, predictive power was low, at least partly because the rectal dose

  6. A rare case of medullary carcinoma of the colon presenting as intussusception in an adult with rectal bleeding.

    Jain, Shilpa; Jain, Ankur; Onizuka, Neil; Boukhar, Sarag A


    Medullary carcinoma is a recently recognized rare subtype of colorectal cancer resembling both poorly differentiated adenocarcinoma and neuroendocrine tumors. Medullary carcinoma most commonly presents in the proximal colon and can be differentiated from other right-sided malignant lesions by histology and immunochemical markers. We present here a rare case of an adult patient with rectal bleeding who was found to have an intussusception due to underlying medullary carcinoma of the splenic flexure. A 72-year-old woman presented to our GI clinic with rectal bleeding. Colonoscopy revealed a necrotic mass of the sigmoid colon, later determined by CT to be a colo-colonic intussusception at the level of the splenic flexure. Patient underwent diagnostic laparoscopy with findings of a large splenic flexure mass, which was resected and found to be medullary carcinoma of the colon. The tumor was poorly differentiated and exhibited microsatellite instability but was discovered at an early stage and thus did not require any adjuvant chemotherapy. Unlike most previously reported cases of medullary carcinoma, our patient presented with a left sided tumor. To our knowledge, this is the first report of a medullary colon cancer presenting with intussusception.

    Matthew Packard


    Full Text Available Purpose. To define factors associated with rectal bleeding in patients treated with IG-IMRT followed by Pd-103 seed implant. Methods and Materials. We retrospectively reviewed 61 prostate adenocarcinoma patients from 2002 to 2008. The majority (85.2% were of NCCN intermediate risk category. All received IG-IMRT to the prostate and seminal vesicles followed by Pd-103 implant delivering a mean D90 of 100.7 Gy. Six patients received 45 Gy to the pelvic nodes and 10 received androgen deprivation. Results. Ten patients (16.4% developed rectal bleeding: 4 were CTCAE v.3 grade 1, 5 were grade 2, and 1 was grade 3. By univariate analysis, age, stage, Gleason sum, PSA, hormonal therapy, pelvic radiation, postoperative prostate volume, D9, V100, individual source activity, total implanted activity per cm3, and duration of interval before implant did not impact rectal bleeding. Implant R100 was higher in patients with rectal bleeding: on average, 0.885 versus 0.396 cm3, P=.02, odds ratio of 2.26 per .5 cm3 (95% CI, 1.16–4.82. A trend for significance was seen for prostate V200 and total implanted activity. Conclusion. Higher implant R100 was associated with development of rectal bleeding in patients receiving IG-IMRT to 45 Gy followed by Pd-103 implant. Minimizing implant R100 may reduce the rate of rectal bleeding in similar patients.

  8. Validation of Normal Tissue Complication Probability Predictions in Individual Patient: Late Rectal Toxicity

    Semenenko, Vladimir A., E-mail: [Department of Radiation Oncology, Medical College of Wisconsin, Milwaukee, Wisconsin (United States); Tarima, Sergey S. [Division of Biostatistics, Institute for Health and Society, Medical College of Wisconsin, Milwaukee, Wisconsin (United States); Devisetty, Kiran [Department of Radiation Oncology, Medical College of Wisconsin, Milwaukee, Wisconsin (United States); Pelizzari, Charles A.; Liauw, Stanley L. [Department of Radiation and Cellular Oncology, University of Chicago Pritzker School of Medicine, Chicago, Illinois (United States)


    Purpose: To perform validation of risk predictions for late rectal toxicity (LRT) in prostate cancer obtained using a new approach to synthesize published normal tissue complication data. Methods and Materials: A published study survey was performed to identify the dose-response relationships for LRT derived from nonoverlapping patient populations. To avoid mixing models based on different symptoms, the emphasis was placed on rectal bleeding. The selected models were used to compute the risk estimates of grade 2+ and grade 3+ LRT for an independent validation cohort composed of 269 prostate cancer patients with known toxicity outcomes. Risk estimates from single studies were combined to produce consolidated risk estimates. An agreement between the actuarial toxicity incidence 3 years after radiation therapy completion and single-study or consolidated risk estimates was evaluated using the concordance correlation coefficient. Goodness of fit for the consolidated risk estimates was assessed using the Hosmer-Lemeshow test. Results: A total of 16 studies of grade 2+ and 5 studies of grade 3+ LRT met the inclusion criteria. The consolidated risk estimates of grade 2+ and 3+ LRT were constructed using 3 studies each. For grade 2+ LRT, the concordance correlation coefficient for the consolidated risk estimates was 0.537 compared with 0.431 for the best-fit single study. For grade 3+ LRT, the concordance correlation coefficient for the consolidated risk estimates was 0.477 compared with 0.448 for the best-fit single study. No evidence was found for a lack of fit for the consolidated risk estimates using the Hosmer-Lemeshow test (P=.531 and P=.397 for grade 2+ and 3+ LRT, respectively). Conclusions: In a large cohort of prostate cancer patients, selected sets of consolidated risk estimates were found to be more accurate predictors of LRT than risk estimates derived from any single study.

  9. Predicting risk of upper gastrointestinal bleed and intracranial bleed with anticoagulants: cohort study to derive and validate the QBleed scores.

    Hippisley-Cox, Julia; Coupland, Carol


    To develop and validate risk algorithms (QBleed) for estimating the absolute risk of upper gastrointestinal and intracranial bleed for patients with and without anticoagulation aged 21-99 years in primary care. Open cohort study using routinely collected data from general practice linked to hospital episode statistics data and mortality data during the five year study period between 1 January 2008 and 1 October 2013. 565 general practices in England contributing to the national QResearch database to develop the algorithm and 188 different QResearch practices to validate the algorithm. All 753 general practices had data linked to hospital episode statistics and mortality data at individual patient level. Gastrointestinal bleed and intracranial bleed recorded on either the linked mortality data or the linked hospital records. We studied 4.4 million patients in the derivation cohort with 16.4 million person years of follow-up. During follow-up, 21,641 patients had an incident upper gastrointestinal bleed and 9040 had an intracranial bleed. For the validation cohort, we identified 1.4 million patients contributing over 4.9 million person years of follow-up. During follow-up, 6600 patients had an incident gastrointestinal bleed and 2820 had an intracranial bleed. We excluded patients without a valid Townsend score for deprivation and those prescribed anticoagulants in the 180 days before study entry. Candidate variables recorded on the general practice computer system before entry to the cohort, including personal variables (age, sex, Townsend deprivation score, ethnicity), lifestyle variables (smoking, alcohol intake), chronic diseases, prescribed drugs, clinical values (body mass index, systolic blood pressure), and laboratory test results (haemoglobin, platelets). We also included previous bleed recorded before entry to the study. The final QBleed algorithms incorporated 21 variables. When applied to the validation cohort, the algorithms in women explained 40% of the

  12. Henoch-Schönlein purpura in an older man presenting as rectal bleeding and IgA mesangioproliferative glomerulonephritis: a case report

    Howarth Charles B


    Full Text Available Abstract Introduction Henoch-Schönlein purpura is the most common systemic vasculitis in children. Typical presentations are palpable purpura, abdominal pain, arthritis, and hematuria. This vasculitic syndrome can present as an uncommon cause of rectal bleeding in older patients. We report a case of an older man with Henoch-Schönlein purpura. He presented with rectal bleeding and acute kidney injury secondary to IgA mesangioproliferative glomerulonephritis. Case presentation A 75-year-old Polish man with a history of diverticulosis presented with a five-day history of rectal bleeding. He had first noticed colicky left lower abdominal pain two months previously. At that time he was treated with a 10-day course of ciprofloxacin and metronidazole for possible diverticulitis. He subsequently presented with rectal bleeding to our emergency department. Physical examination revealed generalized palpable purpuric rash and tenderness on his left lower abdomen. Laboratory testing showed a mildly elevated serum creatinine of 1.3. Computed tomography of his abdomen revealed a diffusely edematous and thickened sigmoid colon. Flexible sigmoidoscopy showed severe petechiae throughout the colon. Colonic biopsy showed small vessel acute inflammation. Skin biopsy resulted in a diagnosis of leukocytoclastic vasculitis. Due to worsening kidney function, microscopic hematuria and new onset proteinuria, he underwent a kidney biopsy which demonstrated IgA mesangioproliferative glomerulonephritis. A diagnosis of Henoch-Schönlein purpura was made. Intravenous methylprednisolone was initially started and transitioned to prednisone tapering orally to complete six months of therapy. There was marked improvement of abdominal pain. Skin lesions gradually faded and gastrointestinal bleeding stopped. Acute kidney injury also improved. Conclusion Henoch-Schönlein purpura, an uncommon vasculitic syndrome in older patients, can present with lower gastrointestinal bleeding

  13. Colonoscopic evaluation of minimal rectal bleeding in average-risk patients for colorectal cancer

    Shahriar Nikpour; All All Asgari


    AIM: To assess the prevalence of clinically significant lesions in patients with minimal bright red bleeding per rectum (BRBPR). METHODS: Consecutive outpatients prospectively underwent colonoscopy at Loghman Hakim Hospital, Tehran. Minimal BRBPR was defined as small amounts of red blood after wiping or in the toilet bowl. Patients with the following alarm signs were excluded: Positive personal history of colorectal neoplasms or inflamma-tory bowel disease (IBD), positive first degree family history of colorectal neoplasms, history of altered bow-el habits, recent significant weight loss, and presence of iron deficiency anemia. Neoplastic polyps, colorectal carcinoma, and IBD were defined as significant lesions. RESULTS: A total of 402 patients (183 female and 219 male, aged 43.6±15.7 years) were studied. Hemorrhoids (54.2%), anal fissures (14.2%) and ul-cerative colitis (14.2%) were the most common lesions and colonoscopy was normal in 8.0%. Significant le-sions were found in 121 (30.1%) patients, including 26 patients (6.5%) with adenocarcinoma and 30 (7.5%) with adenomatous polyps. Almost all patients with significant lesions had at least one lesion in the distal colon, an adenocarcinoma and an adenomatous polyp in the proximal colon were found in 2 patients with hemorrhoids. CONCLUSION: Flexible sigmoidoscopy appears to be sufficient for the evaluation of average risk patients with minimal BRBPR. Rigid sigmoidoscopy may be used as an alternative in patients less than 40 years of age in settings where the former is not available. The choice of colonoscopy over flexible sigmoidoscopy in patients aged over 50 years should be individualized.

  15. Diffuse cavernous hemangioma of the rectum: an atypical cause of rectal bleeding Hemangioma cavernoso difuso del recto: una causa atípica de hemorragia digestiva baja

    D. Hervías


    Full Text Available Objective: cavernous hemangioma of the rectosigmoid colon is a rare disease, with no more than 200 cases reported in the literature. The rectosigmoid is the most common site of this disease in the gastrointestinal tract. Case report: we report the case of a 31-year-old male with recurrent episodes of rectal bleeding, who was finally diagnosed of diffuse cavernous hemangioma of the rectum. The tumor, of 12 x 10 x 9 cm in size, occupied the rectum to the margin of the anal sphincter. A surgical procedure was ruled out because of the inability to carry out a safe anastomosis while preserving anal sphincters. Discussion: rectal hemangiomas are less frequent vascular malformations. The clinical presentation of a cavernous hemangioma of the rectum is usually acute, recurrent or chronic rectal bleeding. Other symptoms stem from the possible compression or invasion of adjacent structures, such as lumbar or perianal pain, metrorrhage, hematuria, etc. This diagnosis is commonly made in younger patients. Colonoscopy is without doubt the diagnostic technique of choice, and it allows to establish the localization, morphology, and total extension of the lesion; its characteristic image is a red-purplish nodule with great vascular congestion. According to the opinion of most authors, biopsy is not advisable during colonoscopy, since imaging techniques are sufficient for an accurate diagnosis, and the risk of bleeding while manipulating this lesion is not negligible. Computed tomography and particularly magnetic resonance imaging, given their high precision to delimit the lesion and its relations to adjacent structures, are imaging studies that are mandatory before surgical treatment. Other techniques such as selective angiography, barium enema, gastrointestinal transit, and upper-tract endoscopy may be supplementary and help locate more lesions along the gastrointestinal tract. Failure to recognize the exact diagnosis and extent of diffuse cavernous hemangioma

    Aguilar Sánchez, Víctor; Bravo Paredes, Eduar Alban; Pinto Valdivia, José Luis; Valenzuela Granados, Vanessa; Espinoza-Rios, Jorge Luis


    To validate the score AIMS65 in patients with upper gastrointestinal bleeding, in terms of mortality and rebleeding a 30-day event. Patients included were those with higher age to 18 years attending the Hospital Nacional Cayetano Heredia during the period May 2013 to December 2014, by upper gastrointestinal bleeding. Data were analyzed using ROC curve (Receiver Operating Characteristic) and the area was obtained under the curve (AUC) to properly qualify the score AIMS65. 209 patients were included, 66.03% were male, with an average age of 58.02 years. The mortality rate was 7.65%, the multiorgan failure the most common cause of death. Plus 3.82% of the patients had recurrent bleeding and 11% required a transfusion of more than 2 units of blood. When analyzing the ROC curve with AIMS65 and mortality score a value of 0.9122 is reported; identifying it as cutoff greater than or equal to 3 value in the score AIMS65 to discriminate patients at high risk of death, likewise the ROC curve was analyzed for recurrence of bleeding with a value of 0.6266 and the need to Transfusion of packed red blood cells over two a value of 0.7421. And it was determined the average hospital stay with a value of 4.8 days, however, no correlation was found with the score AIMS65. AIMS65 score is a good predictor of mortality, and is useful for predicting the need for transfusion of more than 2 globular packages. However it is not a good predictor for recurrence of bleeding, or hospital stay.

  19. Validation of the Valve Academic Research Consortium Bleeding Definition in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation.

    The Valve Academic Research Consortium (VARC) has proposed a standardized definition of bleeding in patients undergoing transcatheter aortic valve interventions (TAVI). The VARC bleeding definition has not been validated or compared to other established bleeding definitions so far. Thus, we aimed to investigate the impact of bleeding and compare the predictivity of VARC bleeding events with established bleeding definitions. Between August 2007 and April 2012, 489 consecutive patients with severe aortic stenosis were included into the Bern-TAVI-Registry. Every bleeding complication was adjudicated according to the definitions of VARC, BARC, TIMI, and GUSTO. Periprocedural blood loss was added to the definition of VARC, providing a modified VARC definition. A total of 152 bleeding events were observed during the index hospitalization. Bleeding severity according to VARC was associated with a gradual increase in mortality, which was comparable to the BARC, TIMI, GUSTO, and the modified VARC classifications. The predictive precision of a multivariable model for mortality at 30 days was significantly improved by adding the most serious bleeding of VARC (area under the curve [AUC], 0.773; 95% confidence interval [CI], 0.706 to 0.839), BARC (AUC, 0.776; 95% CI, 0.694 to 0.857), TIMI (AUC, 0.768; 95% CI, 0.692 to 0.844), and GUSTO (AUC, 0.791; 95% CI, 0.714 to 0.869), with the modified VARC definition resulting in the best predictivity (AUC, 0.814; 95% CI, 0.759 to 0.870). The VARC bleeding definition offers a severity stratification that is associated with a gradual increase in mortality and prognostic information comparable to established bleeding definitions. Adding the information of periprocedural blood loss to VARC may increase the sensitivity and the predictive power of this classification. © 2015 The Authors.

  20. PET-Based Treatment Response Evaluation in Rectal Cancer: Prediction and Validation

    Janssen, Marco H.M., E-mail: [Department of Radiation Oncology (MAASTRO), GROW Research Institute, University Medical Centre Maastricht, Maastricht (Netherlands); Oellers, Michel C.; Stiphout, Ruud G.P.M. van [Department of Radiation Oncology (MAASTRO), GROW Research Institute, University Medical Centre Maastricht, Maastricht (Netherlands); Riedl, Robert G. [Department of Pathology, University Medical Centre Maastricht, Maastricht (Netherlands); Bogaard, Jorgen van den; Buijsen, Jeroen; Lambin, Philippe; Lammering, Guido [Department of Radiation Oncology (MAASTRO), GROW Research Institute, University Medical Centre Maastricht, Maastricht (Netherlands)


    Purpose: To develop a positron emission tomography (PET)-based response prediction model to differentiate pathological responders from nonresponders. The predictive strength of the model was validated in a second patient group, treated and imaged identical to the patients on which the predictive model was based. Methods and Materials: Fifty-one rectal cancer patients were prospectively included in this study. All patients underwent fluorodeoxyglucose (FDG) PET-computed tomography (CT) imaging both before the start of chemoradiotherapy (CRT) and after 2 weeks of treatment. Preoperative treatment with CRT was followed by a total mesorectal excision. From the resected specimen, the tumor regression grade (TRG) was scored according to the Mandard criteria. From one patient group (n = 30), the metabolic treatment response was correlated with the pathological treatment response, resulting in a receiver operating characteristic (ROC) curve based cutoff value for the reduction of maximum standardized uptake value (SUV{sub max}) within the tumor to differentiate pathological responders (TRG 1-2) from nonresponders (TRG 3-5). The applicability of the selected cutoff value for new patients was validated in a second patient group (n = 21). Results: When correlating the metabolic and pathological treatment response for the first patient group using ROC curve analysis (area under the curve = 0.98), a cutoff value of 48% SUV{sub max} reduction was selected to differentiate pathological responders from nonresponders (specificity of 100%, sensitivity of 64%). Applying this cutoff value to the second patient group resulted in a specificity and sensitivity of, respectively, 93% and 83%, with only one of the pathological nonresponders being false positively predicted as pathological responding. Conclusions: For rectal cancer, an accurate PET-based prediction of the pathological treatment response is feasible already after 2 weeks of CRT. The presented predictive model could be used to

  1. Prediction models for intracranial hemorrhage or major bleeding in patients on antiplatelet therapy: a systematic review and external validation study.

    Hilkens, N A; Algra, A; Greving, J P


    ESSENTIALS: Prediction models may help to identify patients at high risk of bleeding on antiplatelet therapy. We identified existing prediction models for bleeding and validated them in patients with cerebral ischemia. Five prediction models were identified, all of which had some methodological shortcomings. Performance in patients with cerebral ischemia was poor. Background Antiplatelet therapy is widely used in secondary prevention after a transient ischemic attack (TIA) or ischemic stroke. Bleeding is the main adverse effect of antiplatelet therapy and is potentially life threatening. Identification of patients at increased risk of bleeding may help target antiplatelet therapy. This study sought to identify existing prediction models for intracranial hemorrhage or major bleeding in patients on antiplatelet therapy and evaluate their performance in patients with cerebral ischemia. We systematically searched PubMed and Embase for existing prediction models up to December 2014. The methodological quality of the included studies was assessed with the CHARMS checklist. Prediction models were externally validated in the European Stroke Prevention Study 2, comprising 6602 patients with a TIA or ischemic stroke. We assessed discrimination and calibration of included prediction models. Five prediction models were identified, of which two were developed in patients with previous cerebral ischemia. Three studies assessed major bleeding, one studied intracerebral hemorrhage and one gastrointestinal bleeding. None of the studies met all criteria of good quality. External validation showed poor discriminative performance, with c-statistics ranging from 0.53 to 0.64 and poor calibration. A limited number of prediction models is available that predict intracranial hemorrhage or major bleeding in patients on antiplatelet therapy. The methodological quality of the models varied, but was generally low. Predictive performance in patients with cerebral ischemia was poor. In order to

  2. The value of colonoscopy to assess rectal bleeding in patients referred from Primary Care Units Utilidad de la colonoscopia en pacientes derivados desde Atención Primaria por rectorragia

    A. Sánchez


    Full Text Available Objectives: rectal bleeding is very common in the general population. It is produced mainly because of benign disease originating in the anus and the rectum. Our aim was to evaluate the need for colonoscopy in patients presenting with rectal bleeding. Patients and methods: patients referred from Primary Care Units and complaining of rectal bleeding were included prospectively in a three-month study. All patients underwent a careful medical history along with physical examination, laboratory tests, and colonoscopy. Results: 126 patients with a mean age of 49.2 years (range: 19-80 were studied. Rectal digital examination was abnormal in 75 cases (59.5%. Severe disease was encountered in 22 patients (neoplasm, angiodysplasia, and inflammatory bowel disease; 10 patients had polyps, 6 had colorectal cancer, and 6 had inflammatory bowel disease. Out of 63 patients younger than 50 years, 5 had severe disease, all of them in the form of inflammatory bowel disease. Conclusions: a neoplasm of the rectum and colon in patients younger than 50 years is a rare event. A colonoscopy must be performed in this group of patients to rule out inflammatory bowel disease.Objetivos: la rectorragia es frecuente en la población general.

    Purpose: To measure concordance among genitourinary radiation oncologists in using the National Cancer Institute Common Toxicity Criteria (NCI CTC) and Radiation Therapy Oncology Group (RTOG) grading scales to grade rectal bleeding. Methods and Materials: From June 2013 to January 2014, a Web-based survey was sent to 250 American and Canadian academic radiation oncologists who treat prostate cancer. Participants were provided 4 case vignettes in which patients received radiation therapy and developed rectal bleeding and were asked for management plans and to rate the bleeding according to NCI CTC v.4 and RTOG late toxicity grading (scales provided). In 2 cases, participants were also asked whether they would send the patient for colonoscopy. A multilevel, random intercept modeling approach was used to assess sources of variation (case, respondent) in toxicity grading to calculate the intraclass correlation coefficient (ICC). Agreement on a dichotomous grading scale (low grades 1-2 vs high grades 3-4) was also assessed, using the κ statistic for multiple respondents. Results: Seventy-two radiation oncologists (28%) completed the survey. Forty-seven (65%) reported having either written or been principal investigator on a study using these scales. Agreement between respondents was moderate (ICC 0.52, 95% confidence interval [CI] 0.47-0.58) when using NCI CTC and fair using the RTOG scale (ICC 0.28, 95% CI 0.20-0.40). Respondents who chose an invasive management were more likely to select a higher toxicity grade (P<.0001). Using the dichotomous scale, we observed moderate agreement (κ = 0.42, 95% CI 0.40-0.44) with the NCI CTC scale, but only slight agreement with the RTOG scale (κ = 0.19, 95% CI 0.17-0.21). Conclusion: Low interrater reliability was observed among radiation oncologists grading rectal bleeding using 2 common scales. Clearer definitions of late rectal bleeding toxicity should be constructed to reduce this variability and avoid ambiguity in both

  4. EUS-Assisted Evaluation of Rectal Varices before Banding

    Malay Sharma


    Full Text Available Rectal varices are an important cause of bleed. The bleeding can be sometimes fatal. Endoscopic management is possible and is generally done in emergency situation. Rectal variceal banding is useful. Hemodynamic evaluation has shown that the blood flow in rectal varices is from above downwards; however, the site of banding of rectal varices is unclear. This case series shows that the rectal varices should be banded at the highest point of inflow.

    Miller, Kevin C; Hughes, Lexie E; Long, Blaine C; Adams, William M; Casa, Douglas J


      No evidence-based recommendation exists regarding how far clinicians should insert a rectal thermistor to obtain the most valid estimate of core temperature. Knowing the validity of temperatures at different rectal depths has implications for exertional heat-stroke (EHS) management.   To determine whether rectal temperature (Trec) taken at 4 cm, 10 cm, or 15 cm from the anal sphincter provides the most valid estimate of core temperature (as determined by esophageal temperature [Teso]) during similar stressors an athlete with EHS may experience.   Cross-sectional study.   Laboratory.   Seventeen individuals (14 men, 3 women: age = 23 ± 2 years, mass = 79.7 ± 12.4 kg, height = 177.8 ± 9.8 cm, body fat = 9.4% ± 4.1%, body surface area = 1.97 ± 0.19 m(2)).   Rectal temperatures taken at 4 cm, 10 cm, and 15 cm from the anal sphincter were compared with Teso during a 10-minute rest period; exercise until the participant's Teso reached 39.5°C; cold-water immersion (∼10°C) until all temperatures were ≤38°C; and a 30-minute postimmersion recovery period. The Teso and Trec were compared every minute during rest and recovery. Because exercise and cooling times varied, we compared temperatures at 10% intervals of total exercise and cooling durations for these periods.   The Teso and Trec were used to calculate bias (ie, the difference in temperatures between sites).   Rectal depth affected bias (F2,24 = 6.8, P = .008). Bias at 4 cm (0.85°C ± 0.78°C) was higher than at 15 cm (0.65°C ± 0.68°C, P .05). Bias varied over time (F2,34 = 79.5, P < .001). Bias during rest (0.42°C ± 0.27°C), exercise (0.23°C ± 0.53°C), and recovery (0.65°C ± 0.35°C) was less than during cooling (1.72°C ± 0.65°C, P < .05). Bias during exercise was less than during postimmersion recovery (0.65°C ± 0.35°C, P < .05).   When EHS is suspected, clinicians should insert the flexible rectal thermistor to 15 cm (6 in) because it is the most valid depth.

    García Encinas, Carlos; Bravo Paredes, Eduar; Guzmán Rojas, Patricia; Gallegos López, Roxana; Corzo Maldonado, Manuel; Aguilar Sánchez, Víctor


    To validate the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding, in terms of mortality and recurrent bleeding at 30 days follow-up. Patients older than 60 year-old, with non variceal upper gastrointestinal bleeding demonstrated by endoscopy, who were attended in a third level general hospital from June 2009 to June 2013, were included. Data was analyzed with the ROC (Receiver Operating Characteristic) curve. The area under curve was obtained to assess the Rockall score. One hundred ninety patients were included, 64.2% were males, with an average age of 74 years old. Overall mortality was 16.8% and respiratory failure with second bleeding episode was the most common cause of death (34.3% and 31.3% respectively). 5.52% of patients presented a second bleeding episode. A transfusion of more than 2 blood-packs was needed in the 24.7% of the patients. The area under ROC curve using the Rockall score was 0,76 (IC: 0.68-0.84) for mortality risk, 0.71 (IC: 0.55-0.88) for the risk of rebleeding and 0.66 (IC: 0.58-0.74) for needing a more than 2 blood-packs transfusion. Rockall score is a good predictor for mortality and rebleeding during the 30 day-period after a non-variceal bleeding episode in elderly patients. The best sensibility and specificity was obtained with the scores of 5 and 6, respectively.

  7. Genetic variation influences the risk of bleeding after cardiac surgery: novel associations and validation of previous findings.

    Greiff, G; Pleym, H; Stenseth, R; Wahba, A; Videm, V


    Severe post-operative bleeding in cardiac surgery is associated with increased morbidity and mortality. We hypothesized that variation in genetic susceptibility contributes to post-operative bleeding in addition to clinical factors. We included 1036 adults undergoing cardiac surgery with cardiopulmonary bypass. Two different endpoints for excessive post-operative bleeding were used, either defined as blood loss exceeding 2 ml/kg/h the first 4 h post-operatively or a composite including bleeding, transfusions, and reoperations. Twenty-two single nucleotide polymorphisms (SNPs) central in the coagulation and fibrinolysis systems or in platelet membrane receptors were genotyped, focusing on replication of earlier non-replicated findings and exploration of potential novel associations. Using logistic regression, significant SNPs were added to a model with only clinical variables to evaluate whether the genetic variables provided additional information. Univariate tests identified rs1799809 (located in the promoter region of the PROC gene), rs27646 and rs1062535 (in the ITGA2 gene), rs630014 (in the ABO gene), and rs6048 (in the F9 gene) as significantly associated with excessive post-operative bleeding (P after adjustment with clinical variables, showing almost unchanged odds ratios except for rs1799809 (P = 0.06). Addition of the genetic covariates to a logistic regression model with clinical variables significantly improved the model (P bleeding after cardiac surgery, of which two validated previously published associations. Addition of genetic information to models with only clinical variables improved the models. Our results indicate that common genetic variations significantly influence post-operative bleeding after cardiac surgery. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

    Full Text Available : INTRODUCTION: Rectal foreign bodies are common, but foreign body made of glass with uneven sharp distal end and complicated with hypovolemic shock is very rare. It is very challenging to be removed by laparotomy and poses extra difficulty in emergency. PRESENTATION OF CASE: A 45-year-old man with complains of rectal foreign body and bleeding per rectum reported in emergency room. On examination patient was in hypovolemic shock and continuous bleeding through anal opening. Emergency laparotomy was per-formed and foreign body was retrieved successfully. DISCUSSION: Rectal foreign body made of glass with uneven sharp distal end towards distal end of rectum is very rare. Retrieval of these foreign bodies will be very difficult, especially for the emergency cases that are complicated with hypovolemic shock. Emergency laparotomy can be successfully performed to stop the bleeding and minimize rectal and anal canal trauma. To the best of our knowledge, such rectal foreign body has been rarely reported. CONCLUSION: Rectal foreign body with uneven sharp edges towards anal opening are difficult to retrieve trough transanal route. Hypovolemic shock due to bleeding and rectal perforation is major complications of these foreign bodies. Emergency laparotomy should be done in these cases.

    Montedori, Alessandro; Abraha, Iosief; Chiatti, Carlos; Cozzolino, Francesco; Orso, Massimiliano; Luchetta, Maria Laura; Rimland, Joseph M; Ambrosio, Giuseppe


    Administrative healthcare databases are useful to investigate the epidemiology, health outcomes, quality indicators and healthcare utilisation concerning peptic ulcers and gastrointestinal bleeding, but the databases need to be validated in order to be a reliable source for research. The aim of this protocol is to perform the first systematic review of studies reporting the validation of International Classification of Diseases, 9th Revision and 10th version (ICD-9 and ICD-10) codes for peptic ulcer and upper gastrointestinal bleeding diagnoses. MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched, using appropriate search strategies. We will include validation studies that used administrative data to identify peptic ulcer disease and upper gastrointestinal bleeding diagnoses or studies that evaluated the validity of peptic ulcer and upper gastrointestinal bleeding codes in administrative data. The following inclusion criteria will be used: (a) the presence of a reference standard case definition for the diseases of interest; (b) the presence of at least one test measure (eg, sensitivity, etc) and (c) the use of an administrative database as a source of data. Pairs of reviewers will independently abstract data using standardised forms and will evaluate quality using the checklist of the Standards for Reporting of Diagnostic Accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P) 2015 statement. Ethics approval is not required given that this is a protocol for a systematic review. We will submit results of this study to a peer-reviewed journal for publication. The results will serve as a guide for researchers validating administrative healthcare databases to determine appropriate case definitions for peptic ulcer disease and upper gastrointestinal bleeding, as well as to perform outcome research using

  10. Comparative validation of a novel risk score for predicting bleeding risk in anticoagulated patients with atrial fibrillation: the HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol Concomitantly) score.

    Lip, Gregory Y H; Frison, Lars; Halperin, Jonathan L; Lane, Deirdre A


    The purpose of this study was to investigate predictors of bleeding in a cohort of anticoagulated patients and to evaluate the predictive value of several bleeding risk stratification schemas. The risk of bleeding during antithrombotic therapy in patients with atrial fibrillation (AF) is not homogeneous, and several clinical risk factors have been incorporated into clinical bleeding risk stratification schemas. Current risk stratification schemas for bleeding during anticoagulation therapy have been based on complex scoring systems that are difficult to apply in clinical practice, and few have been derived and validated in AF cohorts. We investigated predictors of bleeding in a cohort of 7,329 patients with AF participating in the SPORTIF (Stroke Prevention Using an ORal Thrombin Inhibitor in Atrial Fibrillation) III and V clinical trials and evaluated the predictive value of several risk stratification schemas by multivariate analysis. Patients were anticoagulated orally with either adjusted-dose warfarin (target international normalized ratio 2 to 3) or fixed-dose ximelagatran 36 mg twice daily. Major bleeding was centrally adjudicated, and concurrent aspirin therapy was allowed in patients with clinical atherosclerosis. By multivariate analyses, significant predictors of bleeding were concurrent aspirin use (hazard ratio [HR]: 2.10; 95% confidence interval [CI]: 1.59 to 2.77; p HR: 1.98; 95% CI: 1.42 to 2.76; p HR: 1.63; 95% CI: 1.23 to 2.17; p = 0.0008); diabetes (HR: 1.47; 95% CI: 1.10 to 1.97; p = 0.009), and heart failure or left ventricular dysfunction (HR: 1.32; 95% CI: 1.01 to 1.73; p = 0.041). Of the tested schemas, the new HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol Concomitantly) score performed best, with a stepwise increase in rates of major bleeding with increasing HAS-BLED score (p(trend) <0.0001). The c statistic for bleeding varied between 0.50 and 0.67 in

  11. Benign (solitary) ulcer of the rectum -- another cause for rectal stricture.

    Chapa, H J; Smith, H J; Dickinson, T A


    Benign rectal ulcer syndrome is an uncommon cause of lower gastrointestinal bleeding. Patients may present with mild, often recurrent, rectal bleeding frequently ascribed to hemorrhoids. Barium enema may be normal during the early, nonulcerative phase of proctitis. Single (or multiple) ulcers with or without rectal stricture are the hallmarks of the radiographic diagnosis. Radiologic demonstration of the ulcer(s) is not required, however, for the diagnosis. Benign rectal ulcer should be included in the differential diagnosis of benign-appearing rectal strictures.

  12. Validation study in four health-care databases: upper gastrointestinal bleeding misclassification affects precision but not magnitude of drug-related upper gastrointestinal bleeding risk.

    Valkhoff, Vera E; Coloma, Preciosa M; Masclee, Gwen M C; Gini, Rosa; Innocenti, Francesco; Lapi, Francesco; Molokhia, Mariam; Mosseveld, Mees; Nielsson, Malene Schou; Schuemie, Martijn; Thiessard, Frantz; van der Lei, Johan; Sturkenboom, Miriam C J M; Trifirò, Gianluca


    To evaluate the accuracy of disease codes and free text in identifying upper gastrointestinal bleeding (UGIB) from electronic health-care records (EHRs). We conducted a validation study in four European electronic health-care record (EHR) databases such as Integrated Primary Care Information (IPCI), Health Search/CSD Patient Database (HSD), ARS, and Aarhus, in which we identified UGIB cases using free text or disease codes: (1) International Classification of Disease (ICD)-9 (HSD, ARS); (2) ICD-10 (Aarhus); and (3) International Classification of Primary Care (ICPC) (IPCI). From each database, we randomly selected and manually reviewed 200 cases to calculate positive predictive values (PPVs). We employed different case definitions to assess the effect of outcome misclassification on estimation of risk of drug-related UGIB. PPV was 22% [95% confidence interval (CI): 16, 28] and 21% (95% CI: 16, 28) in IPCI for free text and ICPC codes, respectively. PPV was 91% (95% CI: 86, 95) for ICD-9 codes and 47% (95% CI: 35, 59) for free text in HSD. PPV for ICD-9 codes in ARS was 72% (95% CI: 65, 78) and 77% (95% CI: 69, 83) for ICD-10 codes (Aarhus). More specific definitions did not have significant impact on risk estimation of drug-related UGIB, except for wider CIs. ICD-9-CM and ICD-10 disease codes have good PPV in identifying UGIB from EHR; less granular terminology (ICPC) may require additional strategies. Use of more specific UGIB definitions affects precision, but not magnitude, of risk estimates. Copyright © 2014 Elsevier Inc. All rights reserved.

  15. Gastric heterotopia of rectum in a child: a mimicker of solitary rectal ulcer syndrome.

    Al-Hussaini, Abdulrahman; Lone, Khurram; Al-Sofyani, Medhat; El Bagir, Asim


    Bleeding per rectum is an uncommon presentation in pediatric patients. Heterotopic gastric mucosa in the rectum is a rare cause of rectal bleeding. Here, we report a 3-year-old child with a bleeding rectal ulcer that was initially diagnosed and managed as a solitary rectal ulcer syndrome. After 1 month, the patient persisted to have intermittent rectal bleed and severe anal pain. Repeat colonoscopy showed the worsening of the rectal ulcer in size. Pediatric surgeon excised the ulcer, and histopathological examination revealed a gastric fundic-type mucosa consistent with the diagnosis of gastric heterotopia of the rectum. Over the following 18 months, our patient had experienced no rectal bleeding and remained entirely asymptomatic. In conclusion, heterotopic gastric mucosa of the rectum should be considered in the differential diagnosis of a bleeding rectal ulcer.

  16. Late effects of radiotherapy on rectum; Les complications rectales de la radiotherapie

    Bosset, J.F.; Bontemps, P.; Courvoisier, P. [Centre Hospitalier Universitaire, 25 - Besancon (France)


    Late rectal morbidity has been observed in 2 % - 25 % of patients treated with radiotherapy using curative doses for prostate, cervix and rectal cancers. The major encountered clinical pictures are rectal proctitis, rectal/anal strictures, rectal bleeding, ulcers and fistula. Some may alter the patient`s lifestyle while other may induce death. Recommendations concerning the clinical practice are described. The treatment of these late rectal effects include nutritional recommendations, laser, formalin application, and surgery. (author)

    Eriksen, Anne Haahr Mellergaard; Andersen, Rikke Fredslund; Pallisgaard, Niels;


    management. Real-time quantitative polymerase chain reaction (RT-qPCR) is commonly used, when measuring miRNA expression. Appropriate normalisation of RT-qPCR data is important to ensure reliable results. The aim of the present study was to identify stably expressed miRNAs applicable as normaliser candidates...... expressed miRNAs for subsequent validation. In the first validation experiment, a panel of miRNAs were analysed on 25 pairs of micro dissected rectal cancer tissue and adjacent stroma. Subsequently, the same miRNAs were analysed in 28 pairs of rectal cancer tissue and normal rectal mucosa. RESULTS: From...... the miRNA profiling experiment, miR-645, miR-193a-5p, miR-27a and let-7g were identified as stably expressed, both in malignant and stromal tissue. In addition, NormFinder confirmed high expression stability for the four miRNAs. In the RT-qPCR based validation experiments, no significant difference...

    Purpose: To propose a random forest normal tissue complication probability (RF-NTCP) model to predict late rectal toxicity following prostate cancer radiation therapy, and to compare its performance to that of classic NTCP models. Methods and Materials: Clinical data and dose-volume histograms (DVH) were collected from 261 patients who received 3-dimensional conformal radiation therapy for prostate cancer with at least 5 years of follow-up. The series was split 1000 times into training and validation cohorts. A RF was trained to predict the risk of 5-year overall rectal toxicity and bleeding. Parameters of the Lyman-Kutcher-Burman (LKB) model were identified and a logistic regression model was fit. The performance of all the models was assessed by computing the area under the receiving operating characteristic curve (AUC). Results: The 5-year grade ≥2 overall rectal toxicity and grade ≥1 and grade ≥2 rectal bleeding rates were 16%, 25%, and 10%, respectively. Predictive capabilities were obtained using the RF-NTCP model for all 3 toxicity endpoints, including both the training and validation cohorts. The age and use of anticoagulants were found to be predictors of rectal bleeding. The AUC for RF-NTCP ranged from 0.66 to 0.76, depending on the toxicity endpoint. The AUC values for the LKB-NTCP were statistically significantly inferior, ranging from 0.62 to 0.69. Conclusions: The RF-NTCP model may be a useful new tool in predicting late rectal toxicity, including variables other than DVH, and thus appears as a strong competitor to classic NTCP models.

  20. Validation of the Rockall scoring system for outcomes from non-variceal upper gastrointestinal bleeding in a Canadian setting

    Robert A Enns; Yves M Gagnon; Alan N Barkun; David Armstrong; Jamie C Gregor; Richard N Fedorak


    AIM: To validate the Rockall scoring system for predicting outcomes of rebleeding, and the need for a surgical procedure and death.METHODS: We used data extracted from the Registry of Upper Gastrointestinal Bleeding and Endoscopy including information of 1869 patients with non-variceal upper gastrointestinal bleeding treated in Canadian hospitals.Risk scores were calculated and used to classify patients based on outcomes. For each outcome, we used x2 goodness-of-fit tests to assess the degree of calibration,and built receiver operating characteristic curves and calculated the area under the curve (AUC) to evaluate the discriminative ability of the scoring system.RESULTS: For rebleeding, the x2 goodness-of-fit test indicated an acceptable fit for the model [x2 (8) = 12.83,P = 0.12]. For surgical procedures [x2 (8) = 5.3, P = 0.73]and death [x2 (8) = 3.78, P = 0.88], the tests showed solid correspondence between observed proportions and predicted probabilities. The AUC was 0.59 (95% CI:0.55-0.62) for the outcome of rebleeding and 0.60 (95% CI: 0.54-0.67) for surgical procedures, representing a poor discriminative ability of the scoring system. For the outcome of death, the AUC was 0.73 (95% CI: 0.69-0.78),indicating an acceptable discriminative ability.CONCLUSION: The Rockall scoring system provides an acceptable tool to predict death, but performs poorly for endpoints of rebleeding and surgical procedures.

    Purpose: Development of user-friendly tools for the prediction of single-patient probability of late rectal toxicity after conformal radiotherapy for prostate cancer. Methods and Materials: This multicenter protocol was characterized by the prospective evaluation of rectal toxicity through self-assessed questionnaires (minimum follow-up, 36 months) by 718 adult men in the AIROPROS 0102 trial. Doses were between 70 and 80 Gy. Nomograms were created based on multivariable logistic regression analysis. Three endpoints were considered: G2 to G3 late rectal bleeding (52/718 events), G3 late rectal bleeding (24/718 events), and G2 to G3 late fecal incontinence (LINC, 19/718 events). Results: Inputs for the nomogram for G2 to G3 late rectal bleeding estimation were as follows: presence of abdominal surgery before RT, percentage volume of rectum receiving >75 Gy (V75Gy), and nomogram-based estimation of the probability of G2 to G3 acute gastrointestinal toxicity (continuous variable, which was estimated using a previously published nomogram). G3 late rectal bleeding estimation was based on abdominal surgery before RT, V75Gy, and NOMACU. Prediction of G2 to G3 late fecal incontinence was based on abdominal surgery before RT, presence of hemorrhoids, use of antihypertensive medications (protective factor), and percentage volume of rectum receiving >40 Gy. Conclusions: We developed and internally validated the first set of nomograms available in the literature for the prediction of radio-induced toxicity in prostate cancer patients. Calculations included dosimetric as well as clinical variables to help radiation oncologists predict late rectal morbidity, thus introducing the possibility of RT plan corrections to better tailor treatment to the patient's characteristics, to avoid unnecessary worsening of quality of life, and to provide support to the patient in selecting the best therapeutic approach.

  3. [Validation of the Glasgow-Blatchford Scoring System to predict mortality in patients with upper gastrointestinal bleeding in a hospital of Lima, Peru (June 2012-December 2013)].

    Cassana, Alessandra; Scialom, Silvia; Segura, Eddy R; Chacaltana, Alfonso


    Upper gastrointestinal bleeding is a major cause of hospitalization and the most prevalent emergency worldwide, with a mortality rate of up to 14%. In Peru, there have not been any studies on the use of the Glasgow-Blatchford Scoring System to predict mortality in upper gastrointestinal bleeding. The aim of this study is to perform an external validation of the Glasgow-Blatchford Scoring System and to establish the best cutoff for predicting mortality in upper gastrointestinal bleeding in a hospital of Lima, Peru. This was a longitudinal, retrospective, analytical validation study, with data from patients with a clinical and endoscopic diagnosis of upper gastrointestinal bleeding treated at the Gastrointestinal Hemorrhage Unit of the Hospital Nacional Edgardo Rebagliati Martins between June 2012 and December 2013. We calculated the area under the curve for the receiver operating characteristic of the Glasgow-Blatchford Scoring System to predict mortality with a 95% confidence interval. A total of 339 records were analyzed. 57.5% were male and the mean age (standard deviation) was 67.0 (15.7) years. The median of the Glasgow-Blatchford Scoring System obtained in the population was 12. The ROC analysis for death gave an area under the curve of 0.59 (95% CI 0.5-0.7). Stratifying by type of upper gastrointestinal bleeding resulted in an area under the curve of 0.66 (95% CI 0.53-0.78) for non-variceal type. In this population, the Glasgow-Blatchford Scoring System has no diagnostic validity for predicting mortality.

  4. Predictors of variceal or nonvariceal source of upper gastrointestinal bleeding. An etiology predictive score established and validated in a tertiary referral center.

    Matei, Daniela; Groza, Ioana; Furnea, Bogdan; Puie, Lidia; Levi, Cristina; Chiru, Andrei; Cruciat, Carmen; Mester, Gabriela; Vesa, Stefan Cristian; Tantau, Marcel


    BACKGROUND & AIMS. For upper gastrointestinal bleeding (UGIB), guidelines recommend pharmacological treatment before endoscopy. Therefore, it is important to establish an early diagnosis of the variceal or non-variceal source of bleeding. This study aims to analyze the clinical and laboratory parameters which are predictors of the UGIB etiology, and to develop a score for predicting variceal or non-variceal bleeding. METHODS. This study comprised patients presenting to the emergency department of a tertiary care center with UGIB, throughout a 1-year period. Clinical, ultrasound data and laboratory parameters were noted. RESULTS. Of the 517 patients with UGIB, 29.8% had variceal and 70.2% non-variceal bleeding. Six factors were associated with variceal hemorrhage: cirrhosis (OR=10.74, 95% CI: 3.50-32.94, pbleeding: the use of NSAIDs (OR=0.32, 95%CI: 0.13-0.83, p=0.01) and of anticoagulants (OR=0.04, 95%CI: 0.00-0.89, p=0.04). A prediction score for UGIB etiology was designed based on this model. We calculated a cutoff value of 0.968, higher values being predictive of variceal bleeding. Positive predictive value (PPV) and negative predictive value (NPV) were: 82.7% and 97%, respectively. The score was validated prospectively in another group of 162 patients: PPV and NPV were 72.7% and 95.3%, respectively. CONCLUSIONS. Several factors were identified as predictors for the etiology of UGIB. Due to its high PPV and NPV, our UGIB etiology score might be useful in predicting variceal bleeding and could assist in the selection of pharmacological therapy before endoscopy.

  8. Management of rectal varices in portal hypertension


    Rectal varices are portosystemic collaterals that form asa complication of portal hypertension, their prevalencehas been reported as high as 94% in patients withextrahepatic portal vein obstruction. The diagnosis istypically based on lower endoscopy (colonoscopy orsigmoidoscopy). However, endoscopic ultrasonographyhas been shown to be superior to endoscopy in diagnosingrectal varices. Color Doppler ultrasonography isa better method because it allows the calculation of thevelocity of blood flow in the varices and can be used topredict the bleeding risk in the varices. Although rare,bleeding from rectal varices can be life threatening. Themanagement of patients with rectal variceal bleedingis not well established. It is important to ensurehemodynamic stability with blood transfusion and tocorrect any coagulopathy prior to treating the bleedingvarices. Endoscopic injection sclerotherapy has beenreported to be more effective in the management ofactive bleeding from rectal varices with less rebleedingrate as compared to endoscopic band ligation. Transjugularintrahepatic portsystemic shunt alone or incombination with embolization is another method usedsuccessfully in control of bleeding. Balloon-occludedretrograde transvenous obliteration is an emergingprocedure for management of gastric varices that hasalso been successfully used to treat bleeding rectalvarices. Surgical procedures including suture ligationand porto-caval shunts are considered when othermethods have failed.

  9. Solitary rectal ulcer syndrome in children: A literature review

    Dehghani, Seyed Mohsen; Malekpour, Abdorrasoul; HAGHIGHAT, MAHMOOD


    Solitary rectal ulcer syndrome (SRUS) is a benign and chronic disorder well known in young adults and less in children. It is often related to prolonged excessive straining or abnormal defecation and clinically presents as rectal bleeding, copious mucus discharge, feeling of incomplete defecation, and rarely rectal prolapse. SRUS is diagnosed based on clinical symptoms and endoscopic and histological findings. The current treatments are suboptimal, and despite correct diagnosis, outcomes can ...

  13. Four-Week Neoadjuvant Intensity-Modulated Radiation Therapy With Concurrent Capecitabine and Oxaliplatin in Locally Advanced Rectal Cancer Patients: A Validation Phase II Trial

    Arbea, Leire, E-mail: [Department of Oncology, Clinica Universidad de Navarra, Navarra (Spain); Martinez-Monge, Rafael; Diaz-Gonzalez, Juan A.; Moreno, Marta; Rodriguez, Javier [Department of Oncology, Clinica Universidad de Navarra, Navarra (Spain); Hernandez, Jose Luis [Department of General Surgery, Clinica Universidad de Navarra, Navarra (Spain); Sola, Jesus Javier [Department of Pathology, Clinica Universidad de Navarra, Navarra (Spain); Ramos, Luis Isaac [Department of Oncology, Clinica Universidad de Navarra, Navarra (Spain); Subtil, Jose Carlos [Department of Gastroenterology, Clinica Universidad de Navarra, Navarra (Spain); Nunez, Jorge [Department of Preventive Medicine and Public Health, Clinica Universidad de Navarra, Navarra (Spain); Chopitea, Ana; Cambeiro, Mauricio; Gaztanaga, Miren; Garcia-Foncillas, Jesus; Aristu, Javier [Department of Oncology, Clinica Universidad de Navarra, Navarra (Spain)


    Purpose: To validate tolerance and pathological complete response rate (pCR) of a 4-week preoperative course of intensity-modulated radiation therapy (IMRT) with concurrent capecitabine and oxaliplatin (CAPOX) in patients with locally advanced rectal cancer. Methods and Materials: Patients with T3 to T4 and/or N+ rectal cancer received preoperative IMRT (47.5 Gy in 19 fractions) with concurrent capecitabine (825 mg/m{sup 2} b.i.d., Monday to Friday) and oxaliplatin (60 mg/m{sup 2} on Days 1, 8, and 15). Surgery was scheduled 4 to 6 weeks after the completion of chemoradiation. Primary end points were toxicity and pathological response rate. Local control (LC), disease-free survival (DFS), and overall survival (OS) were also analyzed. Results: A total of 100 patients were evaluated. Grade 1 to 2 proctitis was observed in 73 patients (73%). Grade 3 diarrhea occurred in 9% of the patients. Grade 3 proctitis in 18% of the first 50 patients led to reduction of the dose per fraction to 47.5 Gy in 20 treatments. The rate of Grade 3 proctitis decreased to 4% thereafter (odds ratio, 0.27). A total of 99 patients underwent surgery. A pCR was observed in 13% of the patients, major response (96-100% of histological response) in 48%, and pN downstaging in 78%. An R0 resection was performed in 97% of the patients. After a median follow-up of 55 months, the LC, DFS, and OS rates were 100%, 84%, and 87%, respectively. Conclusions: Preoperative CAPOX-IMRT therapy (47.5 Gy in 20 fractions) is feasible and safe, and produces major pathological responses in approximately 50% of patients.

  14. Gastrointestinal bleeding.

    Marek, T A


    Gastrointestinal bleeding remains one of the most important emergencies in gastroenterology. Despite this, only about 100 abstracts concerning gastrointestinal bleeding (excluding bleeding complicating endoscopic procedures) were presented at this year's Digestive Disease Week (DDW; 7-10 May 2011; Chicago, Illinois, USA), accounting for less than 2% of all presented lectures and posters. It seems that the number of such abstracts has been decreasing over recent years. This may be due in part to the high level of medical care already achieved, especially in the areas of pharmacotherapy and endoscopic treatment of gastrointestinal bleeding. In this review of gastrointestinal bleeding, priority has been given to large epidemiological studies reflecting "real life," and abstracts dealing more or less directly with endoscopic management. © Georg Thieme Verlag KG Stuttgart · New York.

    Gastrointestinal haemorrhage (GI) is a serious condition that presents both diagnostic as well as therapeutic challenges. Resuscitation of the patient is the first and most important step in its management followed by measures to localize and treat the exact source and site of bleeding. These modalities are upper and lower GI endoscopies, radionuclide imaging and angiography. Surgery is the last resort to handle the situation, if the patient does not respond to resuscitative measures and the various interventional procedures fail to locate and stop the bleeding. We present a case of upper GI bleeding which presented with massive per rectal bleeding and the patient was not responding to resuscitation with multiple blood transfusions. Ultimately an exploratory laparotomy was done which revealed an extra-intestinal source of bleeding into the lumen of duodenum, presenting as upper GI bleeding.

  16. Gastrointestinal Bleeding Secondary to Calciphylaxis.

    Gupta, Nancy; Haq, Khwaja F; Mahajan, Sugandhi; Nagpal, Prashant; Doshi, Bijal


    BACKGROUND Calciphylaxis is associated with a high mortality that approaches 80%. The diagnosis is usually made when obvious skin lesions (painful violaceous mottling of the skin) are present. However, visceral involvement is rare. We present a case of calciphylaxis leading to lower gastrointestinal (GI) bleeding and rectal ulceration of the GI mucosa. CASE REPORT A 66-year-old woman with past medical history of diabetes mellitus, hypertension, end-stage renal disease (ESRD), recently diagnosed ovarian cancer, and on hemodialysis (HD) presented with painful black necrotic eschar on both legs. The radiograph of the legs demonstrated extensive calcification of the lower extremity arteries. The hospital course was complicated with lower GI bleeding. A CT scan of the abdomen revealed severe circumferential calcification of the abdominal aorta, celiac artery, and superior and inferior mesenteric arteries and their branches. Colonoscopy revealed severe rectal necrosis. She was deemed to be a poor surgical candidate due to comorbidities and presence of extensive vascular calcifications. Recurrent episodes of profuse GI bleeding were managed conservatively with blood transfusion as needed. Following her diagnosis of calciphylaxis, supplementation with vitamin D and calcium containing phosphate binders was stopped. She was started on daily hemodialysis with low calcium dialysate bath as well as intravenous sodium thiosulphate. The clinical condition of the patient deteriorated. The patient died secondary to multiorgan failure. CONCLUSIONS Calciphylaxis leading to intestinal ischemia/perforation should be considered in the differential diagnosis in ESRD on HD presenting with abdominal pain or GI bleeding.

    BACKGROUND:: Retrospective single-center studies have shown that diffusion-weighted magnetic resonance imaging (DWI) is promising for identification of patients with rectal cancer with a complete tumor response after neoadjuvant chemoradiotherapy (CRT), using certain volumetric thresholds.\

  18. Primary non-variceal upper gastrointestinal bleeding in NSAID and low-dose aspirin users: development and validation of risk scores for either medication in two large Dutch cohorts.

    de Groot, Nicolette L; Hagenaars, Matthijs P; Smeets, Hugo M; Steyerberg, Ewout W; Siersema, Peter D; van Oijen, Martijn G H


    Non-steroidal anti-inflammatory drugs (NSAIDs) and low-dose acetylsalicylic acid (ASA) have several adverse gastrointestinal (GI) effects, including upper GI bleeding. We aimed to develop a simple risk score to identify high risk NSAID and ASA users for primary upper GI bleeding. Using data from two large anonymized health insurance databases, we defined a development and validation cohort with NSAID and ASA users which were followed-up for the occurrence of a primary upper GI bleeding. Cox regression analyses identified risk factors which were combined into simple risk scores. C-statistics were used to evaluate the discriminative ability of these scores in a validation cohort. In total, 421 cases of upper GI bleeding were identified in the initial cohort of 784,263 NSAID users (incidence rate 54.2 per 10,000 person-years), while 1,295 cases of upper GI bleeding were identified in 235,531 ASA users (incidence rate 37.9 per 10,000 person-years). The risk of upper GI bleeding increased with a higher risk score, which for NSAID users included age, male gender, anemia and concomitant use of ASA or anticoagulants. For ASA users, age, anemia, diabetes and concomitant use of other antiplatelet drugs or anticoagulants were included in the risk score. The C-statistics in the validation cohort were 0.68 and 0.63 or NSAID and ASA users, respectively. Risk factors for primary upper GI bleeding are to a large extent similar for NSAID and ASA users. Using a risk score based on these risk factors, patients at the highest risk can be identified with moderate accuracy.

  19. Primary rectal melanoma - a case report

    Somak Das


    Full Text Available The most common site for malignant melanoma is skin, then eye and third is anorectal region. Primary anorectal malignant melanoma is still very uncommon. It is usually very aggressive and presents with altered bowel habit and rectal bleeding. Proctoscopy shows non-pigmented or lightly pigmented polypoid lesion. Histopathology is confirmatory. Early radical excision is mandatory. A 56 year-old female was presented with malignant melanoma of the lower third of rectum. We report this case for its rarity.

  20. Transanal endoscopic microsurgery for the treatment of uncommon rectal lesions.

    Ferrer-Márquez, Manuel; Rubio-Gil, Francisco; Ortega-Ruiz, Sofía; Blesa-Sierra, Isabel; Álvarez-García, Antonio; Jorge-Cerrudo, Jaime; Vidaña-Márquez, Elisabet; Belda-Lozano, Ricardo; Reina-Duarte, Ángel

    Transanal endoscopic microsurgery (TEM) was developed as a less aggressive alternative treatment for rectal lesions (mainly adenomas and adenocarcinomas). However, its use for other rectal lesions has become more frequent, trying to reduce the morbidity associated with more invasive techniques. The aim of this study is to describe our experience in the use of TEM in other rectal lesions. Retrospective and descriptive study including patients operated with TEM (from June 2008 to December 2016) for the treatment of rectal lesions different from adenomas or adenocarcinomas. Among the 138 patients treated by TEM in our department, 10 patients were operated on for rectal lesions other than adenomas or adenocarcinomas. Rectal lesions were 3neuroendocrine tumours, a neuroendocrine tumour metastasis, a rectal stenosis, a cloacogenic polyp, an endometrioma, a retrorrectal tumour, a presacral abscess and a lesion in the rectovaginal septum. Mean operative time was 72min and postoperative stay was 4.2 days. Only one patient needed a reoperation, due to rectal bleeding. TEM could be a useful tool for the treatment of rectal lesions different from adenomas or adenocarcinomas, potentially decreasing the morbidity associated with more aggressive surgical techniques.

  3. Solitary rectal ulcer syndrome presenting as polypoid mass lesions in a young girl

    Saadah, Omar I; Al-Hubayshi, Maram S; Ghanem, Ahmad T


    Solitary rectal ulcer syndrome (SRUS) is a rare condition in children. We report a case of SRUS in an 8-year old Saudi girl who presented with recurrent rectal bleeding, intermittent mucosal prolapse, and passage of mucus per rectum. Colonoscopy revealed multiple polypoid mass lesions with histopathological features of SRUS. The polypoid variant of SRUS is very rare in children and may be confused with rectal malignant or inflammatory conditions.

  4. Balloon-Occluded Antegrade Transvenous Sclerotherapy to Treat Rectal Varices: A Direct Puncture Approach to the Superior Rectal Vein Through the Greater Sciatic Foramen Under CT Fluoroscopy Guidance

    Rectal varices occur in 44.5 % of patients with ectopic varices caused by portal hypertension, and 48.6 % of these patients are untreated and followed by observation. However, bleeding occurs in 38 % and shock leading to death in 5 % of such patients. Two patients, an 80-year-old woman undergoing treatment for primary biliary cirrhosis (Child-Pugh class A) and a 63-year-old man with class C hepatic cirrhosis (Child-Pugh class A), in whom balloon-occluded antegrade transvenous sclerotherapy was performed to treat rectal varices are reported. A catheter was inserted by directly puncturing the rectal vein percutaneously through the greater sciatic foramen under computed tomographic fluoroscopy guidance. In both cases, the rectal varices were successfully treated without any significant complications, with no bleeding from rectal varices after embolization.

  5. Recurrent bleeding after perimesencephalic hemorrhage.

    Kauw, Frans; Velthuis, Birgitta K; Kizilates, Ufuk; van der Schaaf, Irene C; Rinkel, Gabriel J E; Vergouwen, Mervyn D I


    Perimesencephalic hemorrhage (PMH) is a type of subarachnoid hemorrhage with excellent long-term outcomes. Only one well-documented case of in-hospital rebleeding after PMH is described in the literature, which occurred after initiating antithrombotic treatment because of myocardial ischemia. In this case report we describe a patient with PMH without antithrombotic treatment who had two episodes of recurrent bleeding on the day of ictus. In order to validate the radiological findings we conducted a case-control study. Six neuroradiologists and two neuroradiology fellows performed a blinded assessment of serial unenhanced head CT scans of eight patients with a perimesencephalic bleeding pattern (1 index patient, 6 patients with PMH, 1 patient with a perimesencephalic bleeding pattern and basilar artery aneurysm) to investigate a potential increase in amount of subarachnoid blood. A 56-year-old woman with a perimesencephalic bleeding pattern and negative CT angiography had after the onset headache two episodes with a sudden increase of the headache. Blinded assessment of serial head CTs of eight patients with a perimesencephalic bleeding pattern identified the patient who was clinically suspected to have two episodes of recurrent bleeding to have an increased amount of subarachnoid blood on two subsequent CT scans. Recurrent bleeding after PMH may also occur in patients not treated with antithrombotics. Even after early rebleeding, prognosis of PMH is excellent. Copyright © 2017 Elsevier Inc.

  6. Solitary rectal ulcer syndrome in children: a report of six cases.

    Urgancı, Nafiye; Kalyoncu, Derya; Eken, Kamile Gulcin


    Solitary rectal ulcer syndrome (SRUS) is a rare, benign disorder in children that usually presents with rectal bleeding, constipation, mucous discharge, prolonged straining, tenesmus, lower abdominal pain, and localized pain in the perineal area. The underlying etiology is not well understood, but it is secondary to ischemic changes and trauma in the rectum associated with paradoxical contraction of the pelvic floor and the external anal sphincter muscles; rectal prolapse has also been implicated in the pathogenesis. This syndrome is diagnosed based on clinical symptoms and endoscopic and histological findings, but SRUS often goes unrecognized or is easily confused with other diseases such as inflammatory bowel disease, amoebiasis, malignancy, and other causes of rectal bleeding such as a juvenile polyps. SRUS should be suspected in patients experiencing rectal discharge of blood and mucus in addition to previous disorders of evacuation. We herein report six pediatric cases with SRUS.

  8. Prospective multicenter validation of the Glasgow Blatchford bleeding score in the management of patients with upper gastrointestinal hemorrhage presenting at an emergency department.

    Aquarius, Michel; Smeets, Fabiënne G M; Konijn, Helena W; Stassen, Patricia M; Keulen, Eric T; Van Deursen, Cees T; Masclee, Ad A M; Keulemans, Yolande C


    The Glasgow Blatchford Bleeding Score (GBS) has been developed to assess the need for treatment in patients with acute upper gastrointestinal hemorrhage (UGIH) presenting at emergency departments (EDs). We aimed (a) to determine the validity of the GBS and Rockall scoring systems for prediction of need for treatment and (b) to identify the optimal cut-off value of the GBS. We carried out a population-based, prospective multicenter study of 520 consecutive patients presenting with acute UGIH at EDs of three hospitals. The accuracy of GBS and Rockall scores in predicting the need for treatment (i.e. endoscopic, surgical, or radiological intervention and blood transfusion) was analyzed using receiver operating characteristic curves. Receiver operating characteristic curve analysis showed that the GBS had a good discriminative ability to determine the need for treatment in patients with acute UGIH (area under the curve: 0.88; 95% confidence interval: 0.85-0.91). The GBS was superior to both the clinical Rockall and the full Rockall score in predicting the need for treatment (area under the curve: 0.86 vs. 0.70 vs. 0.77). At a cut-off value of up to 2, the GBS had the optimal combination of sensitivity (99.4%) and specificity (42.4%). The GBS is superior compared with both Rockall scores in predicting the need for treatment in patients with suspected acute UGIH presenting at EDs in the Netherlands. Patients with a GBS of 2 or less form a subgroup of low-risk patients. These low-risk patients are eligible for outpatient management, which might reduce hospital admissions and healthcare costs.

  9. Acute upper gastrointestinal bleeding.

    Kurien, Matthew; Lobo, Alan J


    Acute upper gastrointestinal bleeding (AUGIB) is a frequently encountered medical emergency with an incidence of 84-160/100000 and associated with mortality of approximately 10%. Guidelines from the National Institute for Care and Care Excellence outline key features in the management of AUGIB. Patients require prompt resuscitation and risk assessment using validated tools. Upper gastrointestinal endoscopy provides accurate diagnosis, aids in estimating prognosis and allows therapeutic intervention. Endoscopy should be undertaken immediately after resuscitation in unstable patients and within 24 hours in all other patients. Interventional radiology may be required for bleeding unresponsive to endoscopic intervention. Drug therapy depends on the cause of bleeding. Intravenous proton pump inhibitors should be used in patients with high-risk ulcers. Terlipressin and broad-spectrum antibiotics should be used following variceal haemorrhage. Hospitals admitting patients with AUGIB need to provide well organised services and ensure access to relevant services for all patients, and particularly to out of hours endoscopy. © Royal College of Physicians 2015.

  11. Learning Curves in Robotic Rectal Cancer Surgery: A literature Review



    Full Text Available Background Laparoscopic rectal cancer surgery offers several advantages over open surgery, including quicker recovery, shorter hospital stay and improved cosmesis. However, laparoscopic rectal surgery is technically difficult and is associated with a long learning curve. The last decade has seen the emergence of robotic rectal cancer surgery. In contrast to laparoscopy, robotic surgery offers stable 3D views with advanced dexterity and ergonomics in narrow spaces such as the pelvis. Whether this translates into a shorter learning curve is still debated. The aim of this literature search is to ascertain the learning curve of robotic rectal cancer surgery. Methods This review analyses the literature investigating the learning curve of robotic rectal cancer surgery. Using the Medline database a literature search of articles investigating the learning curve of robotic rectal surgery was performed. All relevant articles were included. Results Twelve original studies fulfilled the inclusion criteria. The current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. Conclusions There are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and outcome reporting. Nevertheless, current evidence suggests that robotic rectal surgery might be easier to learn than laparoscopy. Further well designed studies applying CUSSUM analysis are required to validate this motion.

  13. Management of nonvariceal upper gastrointestinal bleeding.

    Wee, E


    Nonvariceal upper gastrointestinal bleeding is unique from variceal bleeding in terms of patient characteristics, management, rebleeding rates, and prognosis, and should be managed differently. The majority of nonvariceal upper gastrointestinal bleeds will not rebleed once treated successfully. The incidence is 80 to 90% of all upper gastrointestinal bleeds and the mortality is between 5 to 10%. The causes include nonacid-related ulceration from tumors, infections, inflammatory disease, Mallory-Weiss tears, erosions, esophagitis, dieulafoy lesions, angiodysplasias, gastric antral vascular ectasia, and portal hypertensive gastropathy. Rarer causes include hemobilia, hemosuccus pancreaticus, and aortoenteric fistulas. Hematemesis and melena are the key features of bleeding from the upper gastrointestinal tract, but fresh per rectal bleeding may be present in a rapidly bleeding lesion. Resuscitation and stabilization before endoscopy leads to improved outcomes. Fluid resuscitation is essential to avoid hypotension. Though widely practiced, there is currently insufficient evidence to show that routine red cell transfusion is beneficial. Coagulopathy requires correction, but the optimal international normalized ratio has not been determined yet. Risk stratification scores such as the Rockall and Glasgow-Blatchford scores are useful to predict rebleeding, mortality, and to determine the urgency of endoscopy. Evidence suggests that high-dose proton pump inhibitors (PPI) should be given as an infusion before endoscopy. If patients are intolerant of PPIs, histamine-2 receptor antagonists can be given, although their acid suppression is inferior. Endoscopic therapy includes thermal methods such as coaptive coagulation, argon plasma coagulation, and hemostatic clips. Four quadrant epinephrine injections combined with either thermal therapy or clipping reduces mortality. In hypoxic patients, endoscopy masks allow high-flow oxygen during upper gastrointestinal endoscopy. The

  16. Rectal dose-volume constraints in high-dose radiotherapy of localized prostate cancer.

    Fiorino, Claudio; Sanguineti, Giuseppe; Cozzarini, Cesare; Fellin, Gianni; Foppiano, Franca; Menegotti, Loris; Piazzolla, Anna; Vavassori, Vittorio; Valdagni, Riccardo


    To investigate the relationship between rectal bleeding and dosimetric-clinical parameters in patients receiving three-dimensional conformal radiotherapy (3D-CRT) for localized prostate cancer. In a retrospective national study (AIROPROS01-01, AIRO: Associazione Italiana Radioterapia Oncologica), planning/clinical data for 245 consecutive patients with stage T1-4N0-x prostate carcinoma who underwent 3D-CRT to 70-78 Gy (ICRU point) were pooled from four Italian institutions. The correlation between late rectal bleeding and rectal dose-volume data (the percentage of rectum receiving more than 50, 55, 60, 65, 70, and 75 Gy [V(50-70)]) and other dosimetric and clinical parameters were investigated in univariate (log-rank) and multivariate (Cox regression model) analyses. Median follow-up was 2 years. Twenty-three patients were scored as late bleeders according to a modified RTOG definition (Grade 2: 16; Grade 3: 7); the actuarial 2-year rate was 9.2%. Excepting V75, all median and third quartile V(50-70) values were found to be significantly correlated with late bleeding at univariate analysis. The smallest p value was seen for V(50) below/above the third quartile value (66%). The V70 (cut-off value: 30%) was found to be also predictive for late bleeding. In the high-dose subgroup (74-78 Gy), Grade 3 bleeding was highly correlated with this constraint. The predictive value of both V(50) and V(70) was confirmed by multivariate analyses. The present article provides evidence for correlation between rectal DVH parameters and late rectal bleeding in patients treated with curative intent with 3D-CRT. To keep the rate of moderate/severe rectal bleeding below 5-10%, it seems advisable to limit V(50) to 60-65%, V(60) to 45-50%, and V70 to 25-30%.

  17. Bleed Hole Flow Phenomena Studied


    Boundary-layer bleed is an invaluable tool for controlling the airflow in supersonic aircraft engine inlets. Incoming air is decelerated to subsonic speeds prior to entering the compressor via a series of oblique shocks. The low momentum flow in the boundary layer interacts with these shocks, growing in thickness and, under some conditions, leading to flow separation. To remedy this, bleed holes are strategically located to remove mass from the boundary layer, reducing its thickness and helping to maintain uniform flow to the compressor. The bleed requirements for any inlet design are unique and must be validated by extensive wind tunnel testing to optimize performance and efficiency. To accelerate this process and reduce cost, researchers at the NASA Lewis Research Center initiated an experimental program to study the flow phenomena associated with bleed holes. Knowledge of these flow properties will be incorporated into computational fluid dynamics (CFD) models that will aid engine inlet designers in optimizing bleed configurations before any hardware is fabricated. This ongoing investigation is currently examining two hole geometries, 90 and 20 (both with 5-mm diameters), and various flow features.

    Giovanni D De Palma; Maria Rega; Stefania Masone; Saverio Siciliano; Marcello Persico; Francesca Salvatori; Francesco Maione; Dario Esposito; Antonio Bellino; Giovanni Persico


    The occurrence of leiomyoma of the rectum is uncommon. Most of these lesions are clinically silent and are found incidentally during laparotomy or endoscopic procedures for unrelated conditions. Symptomatic leiomyomas of the rectum are encountered less frequently, with only sporadic reports in the literature. We describe a case of a leiomyoma of the rectum presenting as recurrent lower gastrointestinal hemorrhage and secondary anemia.

Besides improvements in surgical techniques, both neoadjuvant short-course radiotherapy and long-course chemoradiation improve oncological results. Approximately 40–60% of rectal cancer patients treated with neoadjuvant chemoradiation achieve some degree of pathologic response. However, there is no effective method of predicting which patients will respond to neoadjuvant treatment. Recent studies have evaluated the potential of genetic biomarkers to predict outcome in locally advanced rectal adenocarcinoma treated with neoadjuvant chemoradiation. The articles produced by the PubMed search were reviewed for those specifically addressing a genetic profile’s ability to predict response to neoadjuvant treatment in rectal cancer. Although tissue gene microarray profiling has led to promising data in cancer, to date, none of the identified signatures or molecular markers in locally advanced rectal cancer has been successfully validated as a diagnostic or prognostic tool applicable to routine clinical practice.

  6. [Obscure gastrointestinal bleeding].

    Pastor, J; Adámek, S


    Obscure gastrointestinal bleeding represents 5% of all cases of bleeding into the gastrointestinal tract (GIT). The cause of this type of bleeding cannot be found by gastroscopy or colonoscopy - the most common cause being bleeding from the source in the small intestine. In other cases it is bleeding from other parts of the digestive tube which has already stopped or was not noticed during admission endoscopy. Imaging methods (X-ray, CT, MRI, scintigraphy) and endoscopic methods (flexible or capsule enteroscopy) are used in the diagnosis and treatment. If, despite having used these methods, the source of bleeding is not found and the bleeding continues, or if the source is known but the bleeding cannot be stopped by radiologic or endoscopic intervention, surgical intervention is usually indicated. The article provides an overview of current diagnostic and treatment options, including instructions on how to proceed in these diagnostically difficult situations.

  7. Rectal mucosal prolapse syndrome as an unusual gastrointestinal manifestation of Sjögren's syndrome: a case report

    Koga Hideki


    Full Text Available Abstract Introduction Rectal mucosal prolapse syndrome, histologically characterized by fibromuscular obliteration in the lamina propria, hyperplastic glands and thickened muscularis mucosa, causes rectal bleeding. Sjögren's syndrome is an autoimmune exocrinopathy that chiefly destroys the salivary and lacrimal glands by lympho-plasmacytic infiltration. Although various gastrointestinal manifestations have been reported in patients with Sjögren's syndrome, there have not been to our knowledge any case reports to date of rectal mucosal prolapse syndrome in association with Sjögren's syndrome. Case presentation A 68-year-old Japanese woman with Sjögren's syndrome and long-term constipation consulted our hospital because of rectal bleeding. Because of dysphagia and xerostomia, she had consistently refused recommendations to take oral medicines including cathartics. Therefore, she frequently strained excessively during defecation. Colonoscopy and radiological examinations disclosed eroded flat protrusions of the rectum. Microscopic examination demonstrated inflamed mucosa with elongated tortuous glands and fibromuscular obliteration. Based on these findings, a diagnosis of rectal mucosal prolapse syndrome was made. Prohibition of straining during defecation and sulfasalazine suppository use were effective. Conclusion This case highlights the importance of defecation control in patients with Sjögren's syndrome. In the case presented, rectal mucosal prolapse syndrome following long-term excessive straining during defecation caused rectal bleeding. Clinicians should consider rectal mucosal prolapse syndrome as a gastrointestinal manifestation of Sjögren's syndrome.

  8. Effect of a prostaglandin - given rectally for prevention of radiation-induced acute proctitis - on late rectal toxicity. Results of phase III randomized, placebo-controlled, double-blind study

    Kertesz, Tereza; Herrmann, Markus K.A.; Christiansen, Hans; Hermann, Robert M.; Hess, Clemens F.; Hille, Andrea [Dept. of Radiotherapy and Radiooncology, Univ. of Goettingen (Germany); Zapf, Antonia [Dept. of Medical Statistics, Univ. of Goettingen (Germany); Pradier, Olivier [Dept. of Radiotherapy and Radiooncology, Univ. of Brest (France); Schmidberger, Heinz [Dept. of Radiotherapy and Radiooncology, Univ. of Mainz (Germany)


    Background and purpose: to assess the late effect of a prostaglandin, given rectally during irradiation, on late rectal toxicity. In the acute treatment setting no significant differences in reducing the incidence of acute proctitis symptoms in patients receiving misoprostol, however, significantly more rectal bleeding had been reported. Patients and methods: a total of 100 patients who had undergone radiotherapy for prostate cancer had been entered into this phase III randomized, placebo-controlled, double-blind study with misoprostol or placebo suppositories. The toxicity was evaluated yearly after cessation of irradiation by the RTOG/LENT-SOMA scale. Results: the median follow-up was 50 months. 20 patients suffered from grade 1, four patients from grade 2 as well, and three patients only from grade 2 toxicity. Frequency, bleeding and urgency were the most commonly reported symptoms. In keeping with other studies and clinical experience, the symptoms peaked within the first 2 years with a median for grade 1 of 13 months and for grade 2 of 15 months. The presence of acute toxicity grade 2 showed a correlation with the development of any late toxicity (p = 0.03). Any acute rectal bleeding was significant correlated with any late rectal bleeding (p = 0.017). Conclusion: misoprostol given as once-daily suppository for prevention of acute radiation-induced proctitis does neither influence the incidence and severity of radiation-induced acute nor late rectal toxicity. Misoprostol has no negative impact on the incidence and severity of late rectal bleeding, in contrast to acute rectal bleeding. The routine clinical use of misoprostol suppositories cannot be recommended. (orig.)

  9. Successful treatment of giant rectal varices by modified percutaneous transhepatic obliteration with sclerosant:Report of a case

    Hirotoshi Okazaki; Kazunari Tominaga; Toshio Watanabe; Yasuhiro Fujiwara; Kenji Nakamura; Tetsuo Arakawa; Kazuhide Higuchi; Masatsugu Shiba; Shirou Nakamura; Tomoko Wada; Kazuki Yamamori; Ai Machida; Kaori Kadouchi; Akihiro Tamori


    We present a female patient with continuous melena,diagnosed with rectal variceal bleeding. She had a history of esophageal varices, which were treated with endoscopic therapy. Five years after the treatment of esophageal varices, continuous melena occurred. Since colonoscopy showed that the melena was caused by giant rectal varices, we thought that they were not suitable to receive endoscopic treatment. We chose the modified percutaneous transhepatic obliteration with sclerosant, which is one of the interventional radiology techniques but a new clinical procedure for rectal varices.After the patient received this therapy, her condition of rectal varices was markedly improved.

  10. Solitary rectal ulcer syndrome in children: A literature review

    Seyed Mohsen Dehghani; Abdorrasoul Malekpour; Mahmood Haghighat


    Solitary rectal ulcer syndrome (SRUS) is a benign and chronic disorder well known in young adults and less in children.It is often related to prolonged excessive straining or abnormal defecation and clinically presents as rectal bleeding,copious mucus discharge,feeling of incomplete defecation,and rarely rectal prolapse.SRUS is diagnosed based on clinical symptoms and endoscopic and histological findings.The current treatments are suboptimal,and despite correct diagnosis,outcomes can be unsatisfactory.Some treatment protocols for SRUS include conservative management such as family reassurance,regulation of toilet habits,avoidance of straining,encouragement of a high-fiber diet,topical treatments with salicylate,sulfasalazine,steroids and sucralfate,and surgery.In children,SRUS is relatively uncommon but troublesome and easily misdiagnosed with other common diseases,however,it is being reported more than in the past.This condition in children is benign; however,morbidity is an important problem as reflected by persistence of symptoms,especially rectal bleeding.In this review,we discuss current diagnosis and treatment for SRUS.

  11. Hemangioma colorretal Colon rectal hemangioma

    João Batista Pinheiro Barreto


    Full Text Available O hemangioma colorretal (HCR é uma lesão vascular benigna rara, com manifestação clínica geralmente entre 5 e 25 anos de idade. Faz parte do diagnóstico diferencial das causas de hemorragia digestiva baixa, sendo confundido, na maioria das vezes, com entidades mais comuns, como hemorróidas e doenças inflamatórias intestinais. O retardo do diagnóstico ocorre freqüentemente devido ao desconhecimento da doença, com taxas de mortalidade alcançando 40 a 50% na presença de sangramento importante. O caso relatado é de uma paciente de 17 anos de idade, admitida no Serviço de Colo-proctologia do Hospital Universitário - HUUFMA, em setembro de 2005, com anemia e sangramento retal, desde a infância, de forma intermitente e não dolorosa. Apresentado sua história clínica e propedêutica diagnóstica, realizada por meio de exames laboratoriais, endoscopia digestiva alta, colonoscopia e arteriografia de mesentéricas e ilíacas internas. O tratamento cirúrgico realizado foi retossigmoidectomia convencional com anastomose colorretal baixa, com boa evolução pós-operatória, tendo o exame histopatológico da peça cirúrgica ressecada, confirmado o diagnostico.The colon and rectum hemangioma is a rare benign vascular lesion, with clinical features usually between 5 and 25 years of age. It is included in the differential diagnose of the lower digestive bleeding causes, and has been frequently misdiagnosed with other more common entities, like hemorrhoids and bowel inflammatory disease. The late diagnose occurs usually because of the rarity of the disease, with mortality rates reaching 40 to 50% in presence of severe bleeding. We report a case of a 17 years old girl who was admitted at the Coloproctology Service of the Academic Hospital - HUUFMA, in September 2005, with anemia and intermittent rectal bleeding since childhood. Laboratorial findings included laboratorial exams, GI endoscopy, colonoscopy and arteriography of mesenteric and

  12. [Rectal administration of anesthetic agents].

    Ceriana, P; Maurelli, M


    To collect data in the current literature dealing with the diffusion, the reliability and the effectiveness of the rectal administration of anaesthetic drugs. To evaluate differences with parenteral administration. Pharmacokinetics and clinical studies published in recent years in indexed journals. Based on the study methodology, drugs employed and pharmacokinetic parameters evaluated. Factors involved in absorption of drugs from the rectal mucosa, clinical effect and pharmacokinetic data of the following drugs: diazepam, flunitrazepam, midazolam, ketamin and methohexital, then a brief evaluation of other drugs: thiopental, etomidate, morphine and chloral hydrate. The most widely used drugs are benzodiazepines: they are safe, easy to manage and highly effective; among them midazolam has the best kinetic and dynamic pattern. Ketamin is useful during painful diagnostic procedures; with the use of barbiturates there is a greater risk of respiratory depression and more caution must be employed. Wide intervariability of rate of absorption, achievement of plasma levels and clinical effect is a relevant drawback of this technique, such to make it not preferable to the parenteral route, when both are feasible. It deserves, anyway, more consideration, and maintains its validity for the preparation of the paediatric patient to general anaesthesia.

    Acute ischemic proCTitis is a rare pathological condition.We report here a patient presented with massive rectal haemorrhage from a bleeding vessel superimposed on an underlying pathology of ischemic proctitis. This case report illustrates the difficulties in making the clinical distinction between ischemic proctitis and other pathological entities. We also discussed the beneficial role of arteriogram with embolotherapy as an effective therapeutic measure in the management of lower gastrointestinal bleeding. The literature on the subject is reviewed.

  14. Nonvariceal upper gastrointestinal bleeding

    Nonvariceal upper gastrointestinal bleeding (NUGB) remains a major medical problem even after advances in medical therapy with gastric acid suppression and cyclooxygenase (COX-2) inhibitors. Although the incidence of upper gastrointestinal bleeding presenting to the emergency room has slightly decreased, similar decreases in overall mortality and rebleeding rate have not been experienced over the last few decades. Many causes of upper gastrointestinal bleeding have been identified and will be reviewed. Endoscopic, radiographic and angiographic modalities continue to form the basis of the diagnosis of upper gastrointestinal bleeding with new research in the field of CT angiography to diagnose gastrointestinal bleeding. Endoscopic and angiographic treatment modalities will be highlighted, emphasizing a multi-modality treatment plan for upper gastrointestinal bleeding. (orig.)

  15. Upper gastrointestinal bleeding.

    Feinman, Marcie; Haut, Elliott R


    Upper gastrointestinal (GI) bleeding remains a commonly encountered diagnosis for acute care surgeons. Initial stabilization and resuscitation of patients is imperative. Stable patients can have initiation of medical therapy and localization of the bleeding, whereas persistently unstable patients require emergent endoscopic or operative intervention. Minimally invasive techniques have surpassed surgery as the treatment of choice for most upper GI bleeding. Copyright © 2014 Elsevier Inc. All rights reserved.

  16. Acute, nonvariceal upper gastrointestinal bleeding.

    Klein, Amir; Gralnek, Ian M


    Acute, nonvariceal upper gastrointestinal bleeding (UGIB) is a common medical emergency encountered worldwide. Despite medical and technological advances, it remains associated with significant morbidity and mortality. Rapid patient assessment and management are paramount. When indicated, upper endoscopy in patients presenting with acute UGIB is effective for both diagnosis of the bleeding site and provision of endoscopic hemostasis. Endoscopic hemostasis significantly reduces rebleeding rates, blood transfusion requirements, length of hospital stay, surgery, and mortality. Furthermore, early upper endoscopy, defined as being performed within 24 h of patient presentation, improves patient outcomes. A structured approach to the patient with acute UGIB that includes early hemodynamic resuscitation and stabilization, preendoscopic risk stratification using validated instruments, pharmacologic and endoscopic intervention, and postendoscopy therapy is important to optimize patient outcome and assure efficient use of medical resources.

  18. Surgical bleeding in microgravity

    Campbell, M. R.; Billica, R. D.; Johnston, S. L. 3rd


    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Purpose: To predict the grade and incidence of late clinical rectal toxicity through short-term (1 year) mucosal alterations. Methods and Materials: Patients with prostate adenocarcinoma treated with curative or adjuvant radiotherapy underwent proctoscopy a year after the course of radiotherapy. Mucosal changes were classified by the Vienna Rectoscopy Score (VRS). Late toxicity data were analyzed according to the Kaplan-Meier method. Comparison between prognosis groups was performed by log-rank analysis. Results: After a median follow-up time of 45 months (range, 18-99), the 3-year incidence of grade {>=}2 rectal late toxicity according to the criteria of the European Organization for Research and Treatment of Cancer and the Radiation Therapy Oncology Group was 24%, with all patients (24/24; 100%) experiencing rectal bleeding. The occurrence of grade {>=}2 clinical rectal late toxicity was higher in patients with grade {>=}2 (32% vs. 15 %, p = 0.02) or grade {>=}3 VRS telangiectasia (47% vs. 17%, p {<=} 0.01) and an overall VRS score of {>=}2 (31% vs. 16 %, p = 0.04) or {>=}3 (48% vs. 17%, p = 0.01) at the 1-year proctoscopy. Conclusions: Early proctoscopy (1 year) predicts late rectal bleeding and therefore can be used as a surrogate endpoint for late rectal toxicity in studies aimed at reducing this frequent complication.

    Appelt, Ane L; Pløen, John; Harling, Henrik


    BACKGROUND: Abdominoperineal resection is the standard treatment for patients with distal T2 or T3 rectal cancers; however, the procedure is extensive and mutilating, and alternative treatment strategies are being investigated. We did a prospective observational trial to assess whether high-dose...... radiotherapy with concomitant chemotherapy followed by observation (watchful waiting) was successful for non-surgical management of low rectal cancer. METHODS: Patients with primary, resectable, T2 or T3, N0-N1 adenocarcinoma in the lower 6 cm of the rectum were given chemoradiotherapy (60 Gy in 30 fractions......-0) at all timepoints. The most common late toxicity was bleeding from the rectal mucosa; grade 3 bleeding was reported in two (7%) in 30 patients at 1 year and one (6%) of 17 patients at 2 years. There were no unexpected serious adverse reactions or treatment-related deaths. INTERPRETATION: High-dose...

  1. Laparoscopic Rectopexy in Solitary Rectal Ulcer

    Hassan Salmanroughani


    Full Text Available Patients with Solitary Rectal Ulcer Syndrome (SRUS come to a physician with passage of mucus and bloody liquid within defecation. The treatment for SRUS is depended to the severity of symptoms and the existance of rectal prolapse. This study is a report of the assessing of rectopexy as surgical modalities for 62 medical treatment resistant SRUS patients who were referred to the gastrointestinal department of Shahid Sadoughi Medical University and Mojibian hospital. The present non-randomized clinical trial was carried out in 62 SRUS patients from 1991 till 2005. In these patients SRUS was confirmed by histology. They were symptomatic after conservative therapy and referred for surgical intervention. All of them had been undergone abdominal rectopexy by two laparoscopic surgeons. In our study, rectal bleeding and history of digitalization had the highest and lowest frequency of symptoms and signs in our cases respectively. Abdominal rectopexy was done in 39 cases and complete recovery in our cases was 69.23%. Complete recovery rate in cases with dysplasia (63.8% was significantly higher than cases without that (P=0.04. Complete recovery rate in cases that had finger defecation (85% was significantly higher than cases without that (50% (P=0.03. Laparoscopic rectopexy is one of the main surgical techniques for treatment of SRUS. This technique can present complete recovery for SRUS patients. Some of them include topical medications, behavior modification supplemented by fiber and biofeedback and surgery were more available and studied. But it seems that education of SRUS patient conservative treatment remain cornerstone in the SRUS management.

    Abdulaziz I AlGhulayqah


    Full Text Available Background/Aim: Solitary rectal ulcer syndrome (SRUS is a benign, chronic defecation disorder with varied presentations. The aim of this study is to summarize the clinical features, endoscopic findings, histological appearance, and treatment strategies associated with SRUS. Patients and Methods: This is a retrospective study of all patients diagnosed with SRUS at the King Faisal Specialist Hospital and Research Centre in Riyadh from January 2003 to December 2013. Cases were identified using the Department of Pathology database. Data were obtained from medical records that included clinical manifestation, endoscopic findings, and histopathological features. Results: Twenty patients were identified. The mean age was 42.5 years (±18.5 and 55% were females. Most of the patients presented with bleeding per rectum (85%, constipation (75%, and straining (50%, with a mean symptom duration of 26.7 months. The most common associated factors identified were constipation (75%, history of rectal surgery (25%, digital rectal manipulation (20%, and rectal prolapse (20%. Endoscopic findings included a single ulcer (50% and multiple ulcers (30%; 55% had a polypoidal appearance. On histopathology, there was surface ulceration (95%, fibrosis of the lamina propria (60%, distorted architecture (55%, and muscle hypertrophy with increased mucin production (50%. Patients were treated conservatively and none required surgery. Conclusion: SRUS is a rare disorder with variable clinical presentations. Stool softeners, a high fiber diet in addition to topical mesalamine, and biofeedback proved to be effective in this patient population.

  13. TRREMS procedure (transanal repair of rectocele and rectal mucosectomy with one circular stapler: a prospective multicenter trial

    José Vinicius Cruz


    Full Text Available CONTEXT: Since anorectocele is usually associated with mucosa prolapse and/or rectal intussusceptions, it was developed a stapled surgical technique using one circular stapler. OBJECTIVE: To report the results of Transanal Repair of Rectocele and Rectal Mucosectomy with one Circular Stapler (TRREMS procedure in the treatment of anorectocele with mucosa prolapse in a prospective multicenter trial. METHODS: It was conducted by 14 surgeons and included 75 female patients, mean aged 49.6 years, with symptoms of obstructed defecation due to grade 2 (26.7% and grade 3 (73.3% anorectocele associated with mucosa prolapse and/or rectal intussusception (52.0% and an average validated Wexner constipation score of 16. All patients were evaluated by a proctological examination, cinedefecography, anal manometry and colonic transit time. The TRREMS procedure consists of the manual removal of the rectocele wall with circumferential rectal mucosectomy performed with a circular stapler. The mean follow-up time was 21 months. RESULTS: All patients presented obstructed defecation and they persisted with symptoms despite conservative treatment. The mean operative time was 42 minutes. In 13 (17.3% patients, bleeding from the stapled line required hemostatic suture. Stapling was incomplete in 2 (2.6%. Forty-nine patients (65.3% required 1 hospitalization day, the remainder (34.7% 2 days. Postoperatively, 3 (4.0% patients complained of persistent rectal pain and 7 (9.3% developed stricture on the stapled suture subsequently treated by stricturectomy under anesthesia (n = 1, endoscopic stricturectomy with hot biopsy forceps (n = 3 and digital dilatation (n = 3. Postoperative cinedefecography showed residual grade I anorectoceles in 8 (10.6%. The mean Wexner constipation score decreased significantly from 16 to 4 (0-4: n = 68 (6: n = 6 (7: n = 1 (P<0.0001. CONCLUSION: Current trial results suggest that TRREMS procedure is a safe and effective technique for the treatment

  14. A Simple and Safe Procedure to Repair Rectal Prolapse Perineally Using Stapling Devices

    Fumitake Hata


    Full Text Available Rectal prolapses are not life-threatening, however the bleeding and fecal incontinence associated with them significantly erode quality of life and can cause concern among patients' caregivers in nursing homes. Many procedures have been reported that repair rectal prolapses, and the procedure used depends on the severity of the prolapse; however, the treatments are yet to be established. Here we report a simple and safe procedure to repair rectal prolapse perineally using stapling devices. We performed this procedure on 5 patients within a short time. All patients were followed up for over 24 months and none had any recurrences of their rectal prolapses. No complications occurred during the operations and postoperative periods. Most patients who have prolapses are elderly and fragile, so the treatment must be easy, safe, and rapid. While rectal prolapse is not life-threatening, the goal of treatment is to alleviate its symptoms. The procedure we describe is consistent with this concept. We suggest that this procedure, which uses surgical stapling devices, might be a better option for the treatment of complete rectal prolapse. We will continue to surgically correct complete rectal prolapses and investigate the long-term outcomes of the procedure.

  15. Hirschsprung’s disease: Role of rectal suction biopsy - data on 216 specimens

    Rahman, Zillur; Hannan, Jafrul; Islam, Saiful


    Background: The diagnosis of Hirschsprung’s disease (HD) is dependent on the histological study of rectal ganglion cells, and an open rectal biopsy was the mainstay that required general anaesthesia (GA) and carried risk of postoperative rectal bleeding. Suction rectal biopsy later gained wide acceptance and became the choice as there is no requirement of GA and virtual absence of any complications. Materials and Methods: A retrospective review of the histological findings of 216 rectal suction biopsies studied from 2005 to 2009. Results: There were 143 male and 73 female children. 196 (90.7%) children were within 1 year of age. Among 216 rectal suction biopsies 181 (83.80%) were aganglionic, 27 (12.5%) were ganglionic and 8 (3.7%) were inadequate. Majority of patients were of less than 1 year of age (94.47%). Conclusions: The rectal suction biopsy is a bed side procedure, safe, cheap and time saving. There is high degree of accuracy, simplicity and absence of complications. PMID:20975783

Results: There were 143 male and 73 female children. 196 (90.7% children were within 1 year of age. Among 216 rectal suction biopsies 181 (83.80% were aganglionic, 27 (12.5% were ganglionic and 8 (3.7% were inadequate. Majority of patients were of less than 1 year of age (94.47%. Conclusions : The rectal suction biopsy is a bed side procedure, safe, cheap and time saving. There is high degree of accuracy, simplicity and absence of complications.

  17. Management of stage Ⅳ rectal cancer:Palliative options

    Sean M Ronnekleiv-Kelly; Gregory D Kennedy


    Approximately 30% of patients with rectal cancer present with metastatic disease.Many of these patients have symptoms of bleeding or obstruction.Several treatment options are available to deal with the various complications that may afflict these patients.Endorectal stenting,laser ablation,and operative resection are a few of the options available to the patient with a malignant large bowel obstruction.A thorough understanding of treatment options will ensure the patient is offered the most effective therapy with the least amount of associated morbidity.In this review,we describe various options for palliation of symptoms in patients with metastatic rectal cancer.Additionally,we briefly discuss treatment for asymptomatic patients with metastatic disease.

  2. Nd:YAG laser therapy for rectal and vaginal venous malformations.

    Gurien, Lori A; Jackson, Richard J; Kiser, Michelle M; Richter, Gresham T


    Limited therapeutic options exist for rectal and vaginal venous malformations (VM). We describe our center's experience using Nd:YAG laser for targeted ablation of abnormal veins to treat mucosally involved pelvic VM. Records of patients undergoing non-contact Nd:YAG laser therapy of pelvic VM at a tertiary children's hospital were reviewed. Symptoms, operative findings and details, complications, and outcomes were evaluated. Nine patients (age 0-24) underwent Nd:YAG laser therapy of rectal and/or vaginal VM. Rectal bleeding was present in all patients and vaginal bleeding in all females (n = 5). 5/7 patients had extensive pelvic involvement on MRI. Typical settings were 30 (rectum) and 20-25 W (vagina), with 0.5-1.0 s pulse duration. Patients underwent the same-day discharge. Treatment intervals ranged from 14 to 180 (average = 56) weeks, with 6.1-year mean follow-up. Five patients experienced symptom relief with a single treatment. Serial treatments managed recurrent bleeding successfully in all patients, with complete resolution of vaginal lesions in 40% of cases. No complications occurred. Nd:YAG laser treatment of rectal and vaginal VM results in substantial improvement and symptom control, with low complication risk. Given the high morbidity of surgical resection, Nd:YAG laser treatment of pelvic VM should be considered as first line therapy.

  3. Nonvariceal Upper Gastrointestinal Bleeding.

    Rahman, Syed Irfan-Ur; Saeian, Kia


    In the intensive care unit, vigilance is needed to manage nonvariceal upper gastrointestinal bleeding. A focused history and physical examination must be completed to identify inciting factors and the need for hemodynamic stabilization. Although not universally used, risk stratification tools such as the Blatchford and Rockall scores can facilitate triage and management. Urgent evaluation for nonvariceal upper gastrointestinal bleeds requires prompt respiratory assessment, and identification of hemodynamic instability with fluid resuscitation and blood transfusions if necessary. Future studies are needed to evaluate the indication, safety, and efficacy of emerging endoscopic techniques. Copyright © 2016 Elsevier Inc. All rights reserved.

  4. Bayesian network modelling of upper gastrointestinal bleeding

    Aisha, Nazziwa; Shohaimi, Shamarina; Adam, Mohd Bakri


    Bayesian networks are graphical probabilistic models that represent causal and other relationships between domain variables. In the context of medical decision making, these models have been explored to help in medical diagnosis and prognosis. In this paper, we discuss the Bayesian network formalism in building medical support systems and we learn a tree augmented naive Bayes Network (TAN) from gastrointestinal bleeding data. The accuracy of the TAN in classifying the source of gastrointestinal bleeding into upper or lower source is obtained. The TAN achieves a high classification accuracy of 86% and an area under curve of 92%. A sensitivity analysis of the model shows relatively high levels of entropy reduction for color of the stool, history of gastrointestinal bleeding, consistency and the ratio of blood urea nitrogen to creatinine. The TAN facilitates the identification of the source of GIB and requires further validation.

  5. Application of objective clinical human reliability analysis (OCHRA) in assessment of technical performance in laparoscopic rectal cancer surgery.

    Foster, J D; Miskovic, D; Allison, A S; Conti, J A; Ockrim, J; Cooper, E J; Hanna, G B; Francis, N K


    Laparoscopic rectal resection is technically challenging, with outcomes dependent upon technical performance. No robust objective assessment tool exists for laparoscopic rectal resection surgery. This study aimed to investigate the application of the objective clinical human reliability analysis (OCHRA) technique for assessing technical performance of laparoscopic rectal surgery and explore the validity and reliability of this technique. Laparoscopic rectal cancer resection operations were described in the format of a hierarchical task analysis. Potential technical errors were defined. The OCHRA technique was used to identify technical errors enacted in videos of twenty consecutive laparoscopic rectal cancer resection operations from a single site. The procedural task, spatial location, and circumstances of all identified errors were logged. Clinical validity was assessed through correlation with clinical outcomes; reliability was assessed by test-retest. A total of 335 execution errors identified, with a median 15 per operation. More errors were observed during pelvic tasks compared with abdominal tasks (p technical performance of laparoscopic rectal surgery.

  6. Transrectal ultrasound-guided biopsy of the prostate: aspirin increases the incidence of minor bleeding complications

    Halliwell, O.T. [Department of Radiology, Southampton General Hospital, Southampton (United Kingdom)], E-mail:; Yadegafar, G. [Public Health Sciences and Medical Statistics Division, School of Medicine, Southampton General Hospital, Southampton University, Southampton (United Kingdom); Lane, C.; Dewbury, K.C. [Department of Radiology, Southampton General Hospital, Southampton (United Kingdom)


    Aim: To assess whether patients taking aspirin were more likely to experience bleeding complications after transrectal ultrasound (TRUS)-guided prostate biopsy. Materials and methods: Three hundred and eighty-seven patients taking aspirin who underwent prostate biopsy over a 3.5 year period and 731 patients not taking aspirin over a 2 year period returned a questionnaire assessing the incidence and severity of bleeding complications. Results: Patients taking aspirin had a significantly higher cumulative incidence of haematuria and rectal bleeding, but not of haemospermia. They also had a longer mean duration of bleeding, but no increase in bleeding severity. Severe bleeding was very uncommon in both groups and no patients required intervention for bleeding complications. Conclusion: Aspirin exacerbates minor bleeding complications in patients undergoing TRUS guided biopsy of the prostate, but in this large group of aspirin-taking patients no dangerous bleeding complications were encountered. It may be that the risks associated with aspirin cessation outweigh the risks of haemorrhagic complications.

  8. Universal definition of perioperative bleeding in adult cardiac surgery.

    Dyke, Cornelius; Aronson, Solomon; Dietrich, Wulf; Hofmann, Axel; Karkouti, Keyvan; Levi, Marcel; Murphy, Gavin J; Sellke, Frank W; Shore-Lesserson, Linda; von Heymann, Christian; Ranucci, Marco


    Perioperative bleeding is common among patients undergoing cardiac surgery; however, the definition of perioperative bleeding is variable and lacks standardization. We propose a universal definition for perioperative bleeding (UDPB) in adult cardiac surgery in an attempt to precisely describe and quantify bleeding and to facilitate future investigation into this difficult clinical problem. The multidisciplinary International Initiative on Haemostasis Management in Cardiac Surgery identified a common definition of perioperative bleeding as an unmet need. The functionality and usefulness of the UDPB for clinical research was then tested using a large single-center, nonselected, cardiac surgical database. A multistaged definition for perioperative bleeding was created based on easily measured clinical end points, including total blood loss from chest tubes within 12 hours, allogeneic blood products transfused, surgical reexploration including cardiac tamponade, delayed sternal closure, and the need for salvage treatment. Depending on these components, bleeding is graded as insignificant, mild, moderate, severe, or massive. When applied to an established cardiac surgery dataset, the UDPB provided insight into the incidence and outcome of bleeding after cardiac surgery. The proposed UDPB in adult cardiac surgery provides a precise classification of bleeding that is useful in everyday practice as well as in clinical research. Once fully validated, the UDPB may be useful as an institutional quality measure and serve as an important end point in future cardiac surgical research.

  11. Bleeding from a gut lesion as a cause of seizure.

    Watari, Takashi; Tokuda, Yasuharu


    The differential diagnosis of causes of seizure is important since appropriate management depends on correct diagnosis. Making a misdiagnosis of epilepsy may lead to erroneous clinical management, and can be minimised with careful history taking and physical examination. Our educational case illustrates a patient with presumed epilepsy based on a witnessed generalised tonic-clonic seizure; he was ultimately diagnosed as upper gastrointestinal bleeding initially considered by careful attention of vital signs and rectal examination, and confirmed and treated by emergent endoscopy. Paying careful attention to the symptoms and signs in patients with seizure episodes is crucial to establishing a correct causative diagnosis for seizure. 2015 BMJ Publishing Group Ltd.

  16. Influence of image slice thickness on rectal dose-response relationships following radiotherapy of prostate cancer

    Olsson, C.; Thor, M.; Liu, M.; Moissenko, V.; Petersen, S. E.; Høyer, M.; Apte, A.; Deasy, J. O.


    When pooling retrospective data from different cohorts, slice thicknesses of acquired computed tomography (CT) images used for treatment planning may vary between cohorts. It is, however, not known if varying slice thickness influences derived dose-response relationships. We investigated this for rectal bleeding using dose-volume histograms (DVHs) of the rectum and rectal wall for dose distributions superimposed on images with varying CT slice thicknesses. We used dose and endpoint data from two prostate cancer cohorts treated with three-dimensional conformal radiotherapy to either 74 Gy (N = 159) or 78 Gy (N = 159) at 2 Gy per fraction. The rectum was defined as the whole organ with content, and the morbidity cut-off was Grade ≥2 late rectal bleeding. Rectal walls were defined as 3 mm inner margins added to the rectum. DVHs for simulated slice thicknesses from 3 to 13 mm were compared to DVHs for the originally acquired slice thicknesses at 3 and 5 mm. Volumes, mean, and maximum doses were assessed from the DVHs, and generalized equivalent uniform dose (gEUD) values were calculated. For each organ and each of the simulated slice thicknesses, we performed predictive modeling of late rectal bleeding using the Lyman-Kutcher-Burman (LKB) model. For the most coarse slice thickness, rectal volumes increased (≤18%), whereas maximum and mean doses decreased (≤0.8 and ≤4.2 Gy, respectively). For all a values, the gEUD for the simulated DVHs were ≤1.9 Gy different than the gEUD for the original DVHs. The best-fitting LKB model parameter values with 95% CIs were consistent between all DVHs. In conclusion, we found that the investigated slice thickness variations had minimal impact on rectal dose-response estimations. From the perspective of predictive modeling, our results suggest that variations within 10 mm in slice thickness between cohorts are unlikely to be a limiting factor when pooling multi-institutional rectal dose data that include slice thickness

  17. MicroRNA in rectal cancer

    Azadeh Azizian; Jens Gruber; B Michael Ghadimi; Jochen Gaedcke


    In rectal cancer,one of the most common cancers worldwide,the proper staging of the disease determines the subsequent therapy.For those with locally advancedrectal cancer,a neoadjuvant chemoradiotherapy(CRT) is recommended before any surgery.However,response to CRT ranges from complete response(responders) to complete resistance(non-responders).To date we are not able to separate in advance the first group from the second,due to the absence of a valid biomarker.Therefore all patients receive the same therapy regardless of whether they reap benefits.On the other hand almost all patients receive a surgical resection after the CRT,although a watch-and-wait procedure or an endoscopic resection might be sufficient for those who responded well to the CRT.Being highly conserved regulators of gene expression,micro RNAs(mi RNAs) seem to be promising candidates for biomarkers.Many studies have been analyzing the mi RNAs expressed in rectal cancer tissue to determine a specific mi RNA profile for the ailment.Unfortunately,there is only a small overlap of identified mi RNAs between different studies,posing the question as to whether different methods or differences in tissue storage may contribute to that fact or if the results simply are not reproducible,due to unknown factors with undetected influences on mi RNA expression.Other studies sought to find mi RNAs which correlate to clinical parameters(tumor grade,nodal stage,metastasis,survival) and therapy response.Although several mi RNAs seem to have an impact on the response to CRT or might predict nodal stage,there is still only little overlap between different studies.We here aimed to summarize the current literature on rectal cancer and mi RNA expression with respect to the different relevant clinical parameters.

  18. Radiological imaging of rectal cancer

    Lidija Lincender-Cvijetić


    Full Text Available This article discusses the possibilities of diagnosing abdominal imaging in patients with rectal cancer, detecting lesions and assessing the stage of the lesions, in order to select the appropriate therapy. Before the introduction of imaging technologies, the diagnosis of colorectal pathology was based on conventional methods of inspecting intestines with a barium enema, with either a single or double contrast barium enema. Following the development of endoscopic methods and the wide use of colonoscopy, colonoscopy became the method of choice for diagnosing colorectal diseases. The improvement of Computerized Tomography (CT and Magnetic Resonance Imaging (MRI, gave us new possibilities for diagnosing colorectal cancer. For rectal cancer, trans-rectal US (TRUS or endo-anal US (EAUS have a significant role. For staging rectal cancer, the Multi Slice Computed Tomography (MSCT is not the method of choice, but Magnetic Resonance Imaging (MRI is preferred when it comes to monitoring the rectum. Therole of the MRI in the T staging of rectal cancer is crucial in preoperative assessment of: thickness – the width of the tumor, the extramural invasion, the circumference of resection margin (CRM, andthe assessment of the inclusion of mesorectal fascia. For successful execution of surgical techniques, good diagnostic imaging of the cancer is necessary in order to have a low level of recurrence. According to medical studies, the sensitivity of FDG-PET in diagnosing metastatic nodals is low, but for now it is not recommended in routine diagnosis of metastatic colorectal carcinoma.

  19. Dose/volume-response relations for rectal morbidity using planned and simulated motion-inclusive dose distributions

    Thor, Maria; Apte, Aditya; Deasy, Joseph O; Karlsdóttir, Àsa; Moiseenko, Vitali; Liu, Mitchell; Muren, Ludvig Paul


    Background and purpose Many dose-limiting normal tissues in radiotherapy (RT) display considerable internal motion between fractions over a course of treatment, potentially reducing the appropriateness of using planned dose distributions to predict morbidity. Accounting explicitly for rectal motion could improve the predictive power of modelling rectal morbidity. To test this, we simulated the effect of motion in two cohorts. Materials and methods The included patients (232 and 159 cases) received RT for prostate cancer to 70 and 74 Gy. Motion-inclusive dose distributions were introduced as simulations of random or systematic motion to the planned dose distributions. Six rectal morbidity endpoints were analysed. A probit model using the QUANTEC recommended parameters was also applied to the cohorts. Results The differences in associations using the planned over the motion- inclusive dose distributions were modest. Statistically significant associations were obtained with four of the endpoints, mainly at high doses (55–70 Gy), using both the planned and the motion-inclusive dose distributions, primarily when simulating random motion. The strongest associations were observed for GI toxicity and rectal bleeding (Rs=0.12–0.21; Rs=0.11–0.20). Applying the probit model, significant associations were found for tenesmus and rectal bleeding (Rs=0.13, p=0.02). Conclusion Equally strong associations with rectal morbidity were observed at high doses (>55 Gy), for the planned and the simulated dose distributions including in particular random rectal motion. Future studies should explore patient-specific descriptions of rectal motion to achieve improved predictive power. PMID:24231236

  20. Solitary rectal ulcer syndrome: A clinicopathological study of 13 cases

    Al-Brahim Nabeel


    Full Text Available Background/Aims: Solitary rectal ulcer syndrome (SRUS is a rare disorder that has a wide spectrum of clinical presentation and variable endoscopic findings. To further characterize the clinical and pathological features, a retrospective, hospital-based clinicopathological study was conducted. Materials and Methods: All cases of SRUS diagnosed at Farwania Hospital, Kuwait, between 2002 and 2007 were retrieved from the computerized filing system. The histological slides were reviewed by two authors to confirm the diagnosis. Immunohistochemical stain for smooth muscle actin (SMA was performed. The clinical files were reviewed for clinical features and endoscopic findings. Results: Thirteen cases were identified: 8 males and 5 females. The age range was 15-85. Rectal bleeding, constipation, and abdominal pain were the most common presenting symptoms and were seen, either alone or in various combinations, in 12 of the 13 cases. Rectal ulceration was the most common endoscopic finding, being seen in 9 of the13 cases; 3 of these cases had multiple ulcerations. Two patients had rectal polyps, with one of them having multiple polyps. The histological examination revealed surface serration, fibromuscular obliteration of the lamina propria, and crypts′ distortion in all the cases. Seven of the cases had diamond crypts. Ectatic mucosal vessels were a common finding. Positivity for SMA in the lamina propria was seen in all examined cases. Conclusion: SRUS is a rare disorder and only 13 cases were diagnosed in Farwania hospital over a 6-year period. The clinical presentation of our patients was variable. The presence of polyps and multiple ulcerations on endoscopy is further evidence that SRUS is a misnomer. Surface serration, fibromuscular obliteration, and crypts′ distortion are the most characteristic features. The presence of diamond crypts is an additional diagnostic feature.

    Blechschmidt, R.A.; Hohlfeld, O.; Mueller, R.; Werthschuetzky, R. [Technische Univ. Darmstadt (Germany). Inst. fuer Elektromechanische Konstruktionen


    In this paper a pressure sensor probe is presented that is suitable for assessing dynamic rectal pressure profiles. It consists of ten piezoresistive sensors, mounted on low temperature co-fired ceramics. The sensors are coated with a bio-compatible silicone elastomer. It was possible to reduce the size of the ceramic to 4.5 x 5.5 mm with a height of 1.4 mm. The whole probe has a diameter of 9 mm and a length of 20 cm. One healthy test person underwent rectal manometry. The experimental data and the analysis of linearity, hysteresis, temperature stability, and reproducibility are discussed. The presented sensor probe extends the classical anorectal manometry, particularly in view of quantifying disorders of the rectal motility. (orig.)

  3. Upper gastrointestinal bleeding in Kuala Lumpur Hospital, Malaysia.

    Lakhwani, M N; Ismail, A R; Barras, C D; Tan, W J


    Despite advancements in endoscopy and pharmacology in the treatment of peptic ulcer disease the overall mortality has remained constant at 10% for the past four decades. The aim of this study was to determine the age, gender, racial distribution, incidence and causes of endoscopically diagnosed cases of upper gastrointestinal (UGI) bleeding to summarise treatments undertaken and to report their outcome. A prospective study of UGI bleeding in 128 patients was performed in two surgical wards of Kuala Lumpur Hospital, involving both elective and emergency admissions. The study group comprised of 113 (88.2%) males and 15 (11.7%) females. The mean age was 51.9 years (range 14 to 85 years) and 37.5% (48 of 128 patients) were older than 60 years. The Indian race was over-represented in all disease categories. Smoking (50.1%), alcohol consumption (37.5%), non-steroidal anti-inflammatory drugs (NSAIDs) (17.2%), traditional remedies (5.5%), anti-coagulants (2.3%) and steroids (0.8%) were among the risk factors reported. Common presenting symptoms and signs included malaena (68.8%), haematemesis (59.4%) and fresh per rectal bleeding (33.6%). The commonest causes of UGI bleeding were duodenal ulcer (32%), gastric ulcer (29.7%), erosions (duodenal and gastric) (21.9%), oesophageal varices (10.9%) and malignancy (3.9%). UGI bleeding was treated non-surgically in 90.6% of cases. Blood transfusions were required in 62.6% (67/107) of peptic ulcer disease patients. Surgical intervention for bleeding peptic ulcer occurred in around 10% of cases and involved under-running of the bleeding vessel in most high risk duodenal and gastric ulcer patients. The overall mortality from bleeding peptic ulcer disease was 4.7%. Six patients died from torrential UGI haemorrhage soon after presentation, without the establishment of a cause.

  7. Sleeping position and rectal temperature.

    Petersen, S A; Anderson, E S; Lodemore, M; Rawson, D; Wailoo, M P


    The effects of sleeping position upon body temperature were assessed by continuous monitoring of rectal temperature in 137 babies sleeping at home under conditions chosen by their parents. There were three groups of subjects: (1) normal babies aged 12-22 weeks whose temperature rhythms were developed, (2) normal babies aged 6-12 weeks who were developing their night time temperature rhythms, and (3) babies the night after diphtheria, pertussis, and tetanus immunisation, whose temperature rhythms were disturbed. Sleeping in the prone position was not associated with higher rectal temperatures at any time of night in young babies, nor did it exaggerate the disturbance of rectal temperature rhythm after immunisation. In older normal babies the prone position did not disturb rectal temperature in the first part of the night, though prone sleepers warmed a little faster prior to walking, especially in warm conditions. Prone sleepers were, however, born earlier in gestation and tended to be of lower birth weight. Normal babies can therefore thermoregulate effectively whatever their sleeping posture, even in warm conditions, though the prone position may make it slightly more difficult to lose heat. It is difficult to see how the prone position, even interacting with warm conditions, could induce lethal hyperthermia in otherwise normal babies. Perhaps the prone position is associated with other risk factors for sudden infant death syndrome.

  9. Proforma-based reporting in rectal cancer.

    Taylor, F; Mangat, N; Swift, I R; Brown, G


    The improvements in outcomes associate with the use of preoperative therapy rather than postoperative treatment means that clinical teams are increasingly reliant on imaging to identify high-risk features of disease to determine treatment plans. For many solid tumours, including rectal cancer, validated techniques have emerged in identifying prognostic factors pre-operatively. In the MERCURY study, a standardised scanning technique and the use of reporting proformas enabled consistently accurate assessment and documentation of the prognostic factors. This is now an essential tool to enable our clinical colleagues to make treatment decisions. In this review, we describe the proforma-based reporting tool that enables a systematic approach to the interpretation of the magnetic resonance images, thereby enabling all the clinically relevant features to be adequately assessed.

  10. Upper gastrointestinal bleeding etiology score for predicting variceal and non-variceal bleeding

    Supot Pongprasobchai; Sireethorn Nimitvilai; Jaroon Chasawat; Sathaporn Manatsathit


    AIM: To identify clinical parameters, and develop an Upper Gastrointesinal Bleeding (UGIB) Etiology Score for predicting the types of UGIB and validate the score.METHODS: Patients with UGIB who underwent endoscopy within 72 h were enrolled. Clinical and basic laboratory parameters were prospectively collected.Predictive factors for the types of UGIB were identified by univariate and multivariate analyses and were used to generate the UGIB Etiology Score. The best cutoff of the score was defined from the receiver operating curve and prospectively validated in another set of patients with UGIB.RESULTS: Among 261 patients with UGIB, 47 (18%) had variceal and 214 (82%) had non-variceal bleeding.Univariate analysis identified 27 distinct parameters significantly associated with the types of UGIB. Logistic regression analysis identified only 3 independent factors for predicting variceal bleeding;previous diagnosis of cirrhosis or signs of chronic liver disease (OR 22.4, 95% CI 8.3-60.4, P < 0.001), red vomitus (OR4.6, 95% CI 1.8-11.9, P = 0.02), and red nasogastric (NG) aspirate (OR 3.3, 95% CI 1.3-8.3, P = 0.011).The UGIB Etiology Score was calculated from (3.1 x previous diagnosis of cirrhosis or signs of chronic liver disease) + (1.5 × red vornitus) + (1.2 × red NG aspirate), when 1 and 0 are used for the presence and absence of each factor, respectively. Using a cutoff ≥ 3.1, the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) in predicting variceal bleeding were 85%, 81%,82%, 50%, and 96%, respectively. The score was prospectively validated in another set of 195 UGIB cases (46 variceal and 149 non-variceal bleeding). The PPV and NPV of a score ≥3.1 for variceal bleeding were 79% and 97%, respectively.CONCLUSION: The UGIB Etiology Score, composed of 3 parameters, using a cutoff ≥ 3.1 accurately predicted variceal bleeding and may help to guide the choice of initial therapy for UGIB before endoscopy.

  11. Bleeding complications in immune thrombocytopenia.

    Arnold, Donald M


    Bleeding manifestations in patients with immune thrombocytopenia (ITP) range from mild skin bruises to life-threatening intracranial hemorrhage (ICH). Severe bleeding is distinctly uncommon when the platelet count is >30 × 10(9)/L and usually only occurs when the platelet count falls administrative databases, the frequency of ICH in patients with ITP is ~0.5% in children and 1.5% in adults. Estimates of severe (non-ICH) bleeding are difficult to obtain because of the lack of standardized case definitions; the lack of a universally accepted, ITP-specific bleeding assessment tool; and the omission of reporting bleeding outcomes in many clinical studies. In practice, the presence of bleeding should dictate whether or not treatment is needed because many patients, especially children, can be safely managed with observation alone. Guiding principles for the management of ITP, based on the bleeding risk are: (1) Decide when treatment is needed and when it can safely be withheld; (2) for patients with chronic ITP, use the least toxic treatment at the lowest dose; (3) emergency treatment of severe thrombocytopenia-associated bleeding requires combination therapy; and (4) early aggressive therapy may result in durable platelet count responses.

  13. Modern issues on the treatment of peptic ulcer bleedings

    Potakhin S.N.


    Full Text Available Despite the success of therapeutic treatment of peptic ulcer and the introduction of endoscopic technologies, the problem of peptic ulcer hemorrhage remains valid. A large number of publications in foreign literature are dedicated to epidemiology and prevention of bleeding, evaluation of modern tactics and search for new methods of treatment. The works relating to organization of aid to patients with peptic ulcer bleeding are of particular interest. According to the recent data not all clinics even in economically developed countries manage to follow the recommendations of an international consensus-2010 for non-variceal bleeding treatment of upper gastrointestinal tract. Among the causes of non-compliance of international recommendations there are subjective and objective factors, the understanding of which can significantly affect the optimization of aid to patients with peptic ulcer bleeding.

  14. Correlation between tumor regression grade and rectal volume in neoadjuvant concurrent chemoradiotherapy for rectal cancer

    Lee, Hong Seok; Choi, Doo Ho; Park, Hee Chul; Park, Won; Yu, Jeong Il; Chung, Kwangzoo


    Purpose To determine whether large rectal volume on planning computed tomography (CT) results in lower tumor regression grade (TRG) after neoadjuvant concurrent chemoradiotherapy (CCRT) in rectal cancer patients. Materials and Methods We reviewed medical records of 113 patients treated with surgery following neoadjuvant CCRT for rectal cancer between January and December 2012. Rectal volume was contoured on axial images in which gross tumor volume was included. Average axial rectal area (ARA) was defined as rectal volume divided by longitudinal tumor length. The impact of rectal volume and ARA on TRG was assessed. Results Average rectal volume and ARA were 11.3 mL and 2.9 cm². After completion of neoadjuvant CCRT in 113 patients, pathologic results revealed total regression (TRG 4) in 28 patients (25%), good regression (TRG 3) in 25 patients (22%), moderate regression (TRG 2) in 34 patients (30%), minor regression (TRG 1) in 24 patients (21%), and no regression (TRG0) in 2 patients (2%). No difference of rectal volume and ARA was found between each TRG groups. Linear correlation existed between rectal volume and TRG (p = 0.036) but not between ARA and TRG (p = 0.058). Conclusion Rectal volume on planning CT has no significance on TRG in patients receiving neoadjuvant CCRT for rectal cancer. These results indicate that maintaining minimal rectal volume before each treatment may not be necessary. PMID:27592514

  17. Molecular targeted treatment and radiation therapy for rectal cancer

    Marquardt, Friederike; Roedel, Franz; Capalbo, Gianni; Weiss, Christian; Roedel, Claus [Dept. of Radiation Therapy, Univ. of Frankfurt/Main (Germany)


    Background: EGFR (epidermal growth factor receptor) and VEGF (vascular endothelial growth factor) inhibitors confer clinical benefit in metastatic colorectal cancer when combined with chemotherapy. An emerging strategy to improve outcomes in rectal cancer is to integrate biologically active, targeted agents as triple therapy into chemoradiation protocols. Material and methods: cetuximab and bevacizumab have now been incorporated into phase I-II studies of preoperative chemoradiation therapy (CRT) for rectal cancer. The rationale of these combinations, early efficacy and toxicity data, and possible molecular predictors for tumor response are reviewed. Computerized bibliographic searches of Pubmed were supplemented with hand searches of reference lists and abstracts of ASCO and ASTRO meetings. Results: the combination of cetuximab and CRT can be safely applied without dose compromises of the respective treatment components. Disappointingly low rates of pathologic complete remission have been noted in several phase II studies. The K-ras mutation status and the gene copy number of EGFR may predict tumor response. The toxicity pattern (radiation-induced enteritis, perforations) and surgical complications (wound healing, fistula, bleeding) observed in at least some of the clinical studies with bevacizumab and CRT warrant further investigations. Conclusion: longer follow-up (and, finally, randomized trials) is needed to draw any firm conclusions with respect to local and distant failure rates, and toxicity associated with these novel treatment approaches.

  18. Prognosis following upper gastrointestinal bleeding.

    Stephen E Roberts

    Full Text Available BACKGROUND: Upper gastrointestinal (GI bleeding is one of the most common, high risk emergency disorders in the western world. Almost nothing has been reported on longer term prognosis following upper GI bleeding. The aim of this study was to establish mortality up to three years following hospital admission with upper GI bleeding and its relationship with aetiology, co-morbidities and socio-demographic factors. METHODS: Systematic record linkage of hospital inpatient and mortality data for 14 212 people in Wales, UK, hospitalised with upper GI bleeding between 1999 and 2004 with three year follow-up to 2007. The main outcome measures were mortality rates, standardised mortality ratios (SMRs and relative survival. RESULTS: Mortality at three years was 36.7% overall, based on 5215 fatalities. It was highest for upper GI malignancy (95% died within three years and varices (52%. Compared with the general population, mortality was increased 27-fold during the first month after admission. It fell to 4.3 by month four, but remained significantly elevated during every month throughout the three years following admission. The most important independent prognostic predictors of mortality at three years were older age (mortality increased 53 fold for people aged 85 years and over compared with those under 40 years; oesophageal and gastric/duodenal malignancy (48 and 32 respectively and gastric varices aetiologies (2.8 when compared with other bleeds; non-upper GI malignancy, liver disease and renal failure co-morbidities (15, 7.9 and 3.9; social deprivation (29% increase for quintile V vs I; incident bleeds as an inpatient (31% vs admitted with bleeding and male patients (25% vs female. CONCLUSION: Our study shows a high late as well as early mortality for upper GI bleeding, with very poor longer term prognosis following bleeding due to malignancies and varices. Aetiologies with the worst prognosis were often associated with high levels of social

  19. Liver cirrhosis is a risk factor of repeat acute hemorrhagic rectal ulcer in intensive care unit patients

    Pi-Kai Chang


    Full Text Available Background: Acute hemorrhagic rectal ulcer (AHRU can be found in patients with severe comorbid illness, who are bedridden for a long time. Per anal suturing is a quick and feasible treatment. However, recurrent bleeding occurs frequently after suture ligation of a bleeder and can be life-threatening. However, the risk factor for recurrent bleeding is not well known. Our study tries to clarify the risk factor of repeat AHRU in Intensive Care Unit (ICU patients. Materials and Methods: From January 2004 to December 2009, the medical records of 32 patients, who were admitted to the ICU of the Tri-Service General Hospital, a tertiary referral center in Taiwan, and who underwent per anal suturing of acute hemorrhagic rectal ulcer were retrospectively reviewed. Results: Of the 96 patients who received emergency treatment for acute massive hematochezia, 32 patients were diagnosed with AHRU. Eight (25% patients had recurrent bleeding following suture ligation of AHRU and underwent a reoperation; no patient had recurrent bleeding after the second operation. The duration from the first hematochezia attack to surgery (P = 0.04, liver cirrhosis (P = 0.002, and coagulopathy (P = 0.01 were the risk factors of recurrent bleeding after suture ligation of a bleeder. Multivariate logistic regression analysis indicated that liver cirrhosis (OR = 37.77, P = 0.014 was an independent risk factor for recurrent bleeding. Conclusion: AHRU could be a major cause of acute massive hematochezia in patients with severe illness. Our data showed that per anal suturing could quickly and effectively control bleeding. We found that liver cirrhosis was an independent risk factor for recurrent bleeding. Therefore, treatment of a liver cirrhosis patient with AHUR should be more aggressive, such as, early detection and proper suture ligation.

    Chuang-Wei Chen; Shu-Wen Jao; Huang-Jen Lai; Ying-Chun Chiu; Jung-Cheng Kang


    The occurrence of rectal diverticula is very rare, with only sporadic reports in the literature since 1911. Symptomatic rectal diverticula are encountered even less frequently.Treatments of these complicated events range from conservative treatments to major surgical interventions.We present a hitherto unreported occurrence of isolated rectal diverticulum complicated with rectal prolapse and outlet obstruction. Delorme's procedure resulted in subsidence of symptoms and resolution of the diverticulum. It provides a minimal invasive surgical technique to successfully address the reported malady.

  1. Menstrual bleeding after cardiac surgery.

    Hjortdal, Vibeke Elisabeth; Larsen, Signe Holm; Wilkens, Helena; Jakobsen, Anja; Pedersen, Thais Almeida Lins


    We investigated whether open-heart surgery with the use of extracorporeal circulation has an impact on menstrual bleeding. The menstrual bleeding pattern was registered in fertile women undergoing open-heart surgery in 2010-12. Haematocrit and 24-h postoperative bleeding were compared with those of men undergoing cardiac surgery. Women (n = 22), with mean age of 36 (range 17-60) years, were operated on and hospitalized for 4-5 postoperative days. The mean preoperative haematocrit was 40% (range 32-60%), and mean haematocrit at discharge was 32% (range 26-37%). Mean postoperative bleeding in the first 24 h was 312 (range 50-1442) ml. They underwent surgery for atrial septal defect (n = 5), composite graft/David procedure (n = 4), pulmonary or aortic valve replacement (n = 6), myxoma (n = 2), mitral valvuloplasty (n = 2), ascending aortic aneurysm (n = 1), aortic coarctation (n = 1) and total cavopulmonary connection (n = 1). Unplanned menstrual bleeding (lasting 2-5 days) was detected in 13 (60%) patients. Of them, 4 were 1-7 days early, 4 were 8-14 days early, 3 were 1-7 days late and 2 had menstruation despite having had menstrual bleeding within the last 2 weeks. None had unusually large or long-lasting menstrual bleeding. Ten women took oral contraceptives, 8 of whom had unexpected menstrual bleeding during admission. Men (n = 22), with a mean age of 35 (range 17-54) years, had mean bleeding of 331 (range 160-796) ml postoperatively, which was not statistically significantly different from the women's. The mean preoperative haematocrit was 40% (range 29-49%) among men, while haematocrit at discharge was 32% (28-41), not significantly different from that seen in the female subgroup. Menstrual bleeding patterns are disturbed by open-heart surgery in the majority of fertile women. Nevertheless, the unexpected menstrual bleeding is neither particularly long-lasting nor of large quantity, and the postoperative surgical bleeding is unaffected. We recommend that

    David Patch; Lucy Dagher


    @@ TREATMENT STRATEGIES FOR ACUTE VARICEAL BLEEDING Backgound Acute variceal bleeding has a significant mortality which ranges form 5% to 50% in patients with cirrhosis[1].Overall survival is probably improving,because of new therapeutic approaches,and improved medical care.However,mortality is still closely related to failure to control hacmorrhage or carly rebleeding,which is a distinct characteristic of portal hypertensive bleeding and occures in as many as 50% of patients in the first days to 6 weeks after admission et al[2].

    To explore the death-related factors of stageⅠrectal cancer patients. Methods: 89 cases of stage I rectal cancer patients between 1985 and 2000 were retrospectively studied for prognostic factors. Factors including age, gender, tumor size, circumferential occupation, gross type, pathological type, depth of tumor invasion, surgical procedure, adjuvant chemotherapy and postoperative complication were chosen for cox multivariate analysis (forward procedure) using Spss software (10.0 version). Results: multivariate analysis demonstrated that muscular invasion was an independent negative prognostic factor for stageⅠrectal cancer patients (P=0.003). Conclusion: Muscular invasion is a negative prognostic factor for stage I rectal cancer patients.

  5. Robotic rectal surgery: what are the benefits?

    Kim, C W; Baik, S H


    Robotic rectal surgery is not a rare event for colorectal surgeons any more. Even patients with colorectal diseases obtain information through the mass media and are asking surgeons about robotic surgery. Since laparoscopic rectal surgery has proved to have some benefits compared to open rectal surgery, many surgeons became interested in robotic rectal surgery. Some of them have reported the advantages and disadvantages of robotic rectal surgery over the last decade. This review will report on the outcomes of robotic rectal surgery. Robotic rectal surgery requires a longer operation time than laparoscopic or open surgery, but many authors reduced the gap as they were accustomed to the robotic system and used various additional techniques. The high cost for purchasing and maintaining the robotic system is still a problem, though. However, except for this reason, robotic rectal surgery shows comparable and even superior results in some parameters than laparoscopic or open surgery. They include pathologic and functional outcomes as well as short-term outcomes such as complication rates, length of hospital stay, time to recover normal bowel function or first flatus, time to start diet, and postoperative pain. Moreover, studies on oncologic outcomes show acceptable results. Robotic rectal surgery is safe and feasible and has a number of benefits. Therefore, it can be an alternative option to conventional laparoscopic and open surgery with strict indications.

  9. Endoscopic findings of rectal mucosal damage after pelvic radiotherapy for cervical carcinoma: correlation of rectal mucosal damage with radiation dose and clinical symptoms

    Kim, Tae Gyu; Huh, Seung Jae; Park, Won [Dept. of Radiation Oncology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul (Korea, Republic of)


    To describe chronic rectal mucosal damage after pelvic radiotherapy (RT) for cervical cancer and correlate these findings with clinical symptoms and radiation dose. Thirty-two patients who underwent pelvic RT were diagnosed with radiation-induced proctitis based on endoscopy findings. The median follow-up period was 35 months after external beam radiotherapy (EBRT) and intracavitary radiotherapy (ICR). The Vienna Rectoscopy Score (VRS) was used to describe the endoscopic findings and compared to the European Organization for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) morbidity score and the dosimetric parameters of RT (the ratio of rectal dose calculated at the rectal point [RP] to the prescribed dose, biologically effective dose [BED] at the RP in the ICR and EBRT plans, {alpha}/{beta} = 3). Rectal symptoms were noted in 28 patients (rectal bleeding in 21 patients, bowel habit changes in 6, mucosal stools in 1), and 4 patients had no symptoms. Endoscopic findings included telangiectasia in 18 patients, congested mucosa in 20, ulceration in 5, and stricture in 1. The RP ratio, BEDICR, BEDICR+EBRT was significantly associated with the VRS (RP ratio, median 76.5%; BEDICR, median 37.1 Gy3; BEDICR+EBRT, median 102.5 Gy3; p < 0.001). The VRS was significantly associated with the EORTC/RTOG score (p = 0.038). The most prevalent endoscopic findings of RT-induced proctitis were telangiectasia and congested mucosa. The VRS was significantly associated with the EORTC/RTOG score and RP radiation dose.

    Impaired kidney function is a risk factor for upper gastrointestinal (GI) bleeding, an event associated with poor outcomes. The burden of upper GI bleeding and its effect on patients with ESRD are not well described. Using data from the US Renal Data System, we quantified the rates of occurrence of and associated 30-day mortality from acute, nonvariceal upper GI bleeding in patients undergoing dialysis; we used medical claims and previously validated algorithms where available. Overall, 948,345 patients contributed 2,296,323 patient-years for study. The occurrence rates for upper GI bleeding were 57 and 328 episodes per 1000 person-years according to stringent and lenient definitions of acute, nonvariceal upper GI bleeding, respectively. Unadjusted occurrence rates remained flat (stringent) or increased (lenient) from 1997 to 2008; after adjustment for sociodemographic characteristics and comorbid conditions, however, we found a significant decline for both definitions (linear approximation, 2.7% and 1.5% per year, respectively; Pupper GI bleeding episodes and were more likely to receive blood transfusions during an episode. Overall 30-day mortality was 11.8%, which declined significantly over time (relative declines of 2.3% or 2.8% per year for the stringent and lenient definitions, respectively). In summary, despite declining trends worldwide, crude rates of acute, nonvariceal upper GI bleeding among patients undergoing dialysis have not decreased in the past 10 years. Although 30-day mortality related to upper GI bleeding declined, perhaps reflecting improvements in medical care, the burden on the ESRD population remains substantial. PMID:22266666

Consequently, the benefit of such therapies should be balanced against the potential risk of hemorrhagic complications. Therefore, a score to estimate individual risk of bleeding might represent an important tool in clinical decision-making. OBJECTIVE: This study aims to create and validate a bleeding risk score for patients with ACS. METHODS: Independent predictors of bleeding reported by the GRACE Registry were utilized. Variables with odds ratio (OR > 2.5 in that Registry added 3 points (previous history of bleeding, OR = 1.5-2.4 added 2 points (creatinine clearance 30, ST-deviation, peripheral artery disease and smoking. The score was validated in a cohort of 383 individuals with ACS. In-hospital bleeding was defined as hematocrit fall > 10%, blood transfusion > 2 units, intracerebral bleeding or fatal bleeding

  14. Variations in Rectal Volumes and Dosimetry Values Including NTCP due to Interfractional Variability When Administering 2D-Based IG-IMRT for Prostate Cancer

    Takashi Hanada


    Full Text Available We estimated variations in rectal volumes and dosimetry values including NTCP with interfractional motion during prostate IG-IMRT. Rectal volumes, DVH parameters, and NTCPs of 20 patients were analyzed. For this patient population, the median (range volume on the initial plan for the rectum was 45.6 cc (31.3–82.0, showing on-treatment spread around the initial prediction based on the initial plan. DVH parameters of on-treatment CBCT analyses showed systematic regularity shift from the prediction based on the initial plan. Using the Lyman-Kutcher-Burman model, NTCPs of predicted late rectal bleeding toxicity of rectal grade ≥ 2 (RTOG and the QUANTEC update rectal toxicity for the prediction based on the initial plan were 0.09% (0.02–0.24 and 0.02% (0.00–0.07, respectively, with NTCPs from on-treatment CBCT analyses being 0.35% (0.01–6.16 and 0.12% (0.00–4.11, respectively. Using the relative seriality model, for grade ≥ 2 bleeding rectal toxicity, NTCP of the prediction based on the initial plan was 0.64% (0.15–1.22 versus 1.48% (0.18–7.66 for on-treatment CBCT analysis. Interfraction variations in rectal volumes occur in all patients due to physiological changes. Thus, rectal assessment during 2D-based IG-IMRT using NTCP models has the potential to provide useful and practical dosimetric verification.

    In order to improve the benefits of base bleed in base flow field, the base flow with hot base bleed for two jet models is studied. Two-dimensional axisymmetric Navier–Stokes equations are computed by using a finite volume scheme. The base flow of a cylinder afterbody with base bleed is simulated. The simulation results are validated with the experimental data, and the experimental results are well reproduced. On this basis, the base flow fields with base bleed for a circular jet model and an...

  16. Let's Talk Period! Preliminary results of an online bleeding awareness knowledge translation project and bleeding assessment tool promoted on social media.

    Reynen, E; Grabell, J; Ellis, A K; James, P


    Undiagnosed bleeding disorders are common and can pose significant health risks, especially for women. Recently, a self-administered bleeding assessment tool (Self-BAT) was validated in von Willebrand disease. To increase awareness of undiagnosed bleeding disorders through the use of an informational website ( targeted at women in their reproductive years. The Let's Talk Period website was built in consultation with a medical communications company and focus groups of women, with the aim of clearly presenting key messages around menstrual bleeding. The website was promoted through social media and local and national interviews. Upon completion of the online Self-BAT available at, the result is displayed to the user along with a recommendation to seek medical attention if the score is abnormal. During the initial 3-month period, there were 5158 page views from 64 countries. A total of 489 individuals, 95% female, completed the online Self-BAT. The mean Self-BAT score was 6, range 0-44. Abnormal Self-BAT scores were reported in 45% of the respondents, of whom 96% were female. The most commonly reported bleeding symptoms were menorrhagia (98%) and postpartum haemorrhage (82%). Bleeding symptoms were similar across different geographical areas. An online screening tool is an effective method of identifying individuals concerned with abnormal bleeding. A significant portion of the general population report experiencing symptoms of abnormal bleeding. In women, the most frequently reported bleeding symptoms were menorrhagia and postpartum haemorrhage. © 2017 John Wiley & Sons Ltd.

  18. Rectal cancer surgery: volume-outcome analysis.

    Nugent, Emmeline


    There is strong evidence supporting the importance of the volume-outcome relationship with respect to lung and pancreatic cancers. This relationship for rectal cancer surgery however remains unclear. We review the currently available literature to assess the evidence base for volume outcome in relation to rectal cancer surgery.

  19. Multiple rectal carcinoid tumors in monozygotic twins.

    Doi, Momoko; Ikawa, Osamu; Taniguchi, Hiroki; Kawamura, Takuji; Katsura, Kanade


    We report multiple rectal carcinoid tumors in monozygotic twins who, respectively, had 42 and 36 carcinoid tumors in the lower rectum. This is the first report about carcinoid tumors in monozygotic twins. Both twins developed a similar number of rectal carcinoids with a similar distribution. Investigation of their genetic background may provide information about the origin of these tumors.

    Full Text Available BackgroundThe impact on quality of life attributed to treatment for rectal cancer remains high. Deterioration of the urinary function is a relevant complication within that context.ObjectiveTo detect the presence of urinary dysfunction and its risk factors among individuals underwent surgical treatment for rectal cancer.MethodsThe present prospective study analyzed 42 patients from both genders underwent surgical treatment for rectal adenocarcinoma with curative intent. The version of the International Prostatic Symptom Score (IPSS questionnaire validated for the Portuguese language was applied at two time-points: immediately before and 6 months after surgery. Risk factors for urinary dysfunction were analysed by means of logistic regression and Student’s t-test.ResultsEight (19% participants exhibited moderate-to-severe urinary dysfunction 6 months after surgery; the average IPSS increased from 1.43 at baseline to 4.62 six months after surgery (P<0.001. None of the variables assessed as potential risk factors exhibited statistical significance, i.e., age, gender, distance from tumour to anal margin, neoadjuvant therapy, adjuvant therapy, type of surgery, surgical approach (laparoscopy or laparotomy, and duration of surgery.ConclusionThis study identified an incidence of 19% of moderate to severe urinary dysfuction after 6 months surveillance. No risk factor for urinary dysfunction was identified in this population.

  1. Endoscopic management of diverticular bleeding.

    Rustagi, Tarun; McCarty, Thomas R


    Diverticular hemorrhage is the most common reason for lower gastrointestinal bleeding (LGIB) with substantial cost of hospitalization and a median length of hospital stay of 3 days. Bleeding usually is self-limited in 70-80% of cases but early rebleeding is not an uncommon problem that can be reduced with proper endoscopic therapies. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed by interventional endotherapy including injection, heat cautery, clip placement, and ligation to achieve endoscopic hemostasis. This review will serve to highlight the various interventions available to endoscopists with specific emphasis on superior modalities in the endoscopic management of diverticular bleeding.

  5. [Gastrointestinal bleeding: the role of radiology].

    Quiroga Gómez, S; Pérez Lafuente, M; Abu-Suboh Abadia, M; Castell Conesa, J


    Gastrointestinal bleeding represents a diagnostic challenge both in its acute presentation, which requires the point of bleeding to be located quickly, and in its chronic presentation, which requires repeated examinations to determine its etiology. Although the diagnosis and treatment of gastrointestinal bleeding is based on endoscopic examinations, radiological studies like computed tomography (CT) angiography for acute bleeding or CT enterography for chronic bleeding are becoming more and more common in clinical practice, even though they have not yet been included in the clinical guidelines for gastrointestinal bleeding. CT can replace angiography as the diagnostic test of choice in acute massive gastrointestinal bleeding, and CT can complement the endoscopic capsule and scintigraphy in chronic or recurrent bleeding suspected to originate in the small bowel. Angiography is currently used to complement endoscopy for the treatment of gastrointestinal bleeding.

  7. Timing Is Everything: What Is the Optimal Duration After Chemoradiation for Surgery for Rectal Cancer?

    Goodman, Karyn A


    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 47-year-old woman was referred for management of a newly diagnosed rectal cancer. She presented with a 2-month history of rectal bleeding and change in bowel habits. She underwent a colonoscopy that demonstrated a 5-cm fungating, friable, and partially obstructing mass in the distal rectum, approximately 5 cm from the anal verge. The tumor was palpable on digital rectal examination on the anterior wall of rectum. The biopsy demonstrated a moderately differentiated invasive adenocarcinoma, microsatellite stable. A staging work-up, including a computed tomography scan of the chest, abdomen, and pelvis, demonstrated rectal wall thickening in the midrectum and small lymph nodes in the left perirectal fat. There was a nonspecific 3-mm right lower lobe pulmonary nodule. Rectal magnetic resonance imaging demonstrated a 3-cm mass arising from mid-distal rectum with minimal extension beyond muscularis propria into the mesorectal fat, but without invasion of mesorectal fascia (Fig 1). There were at least three small mesorectal lymph nodes present; the largest rounded node measured up to 5 mm, and no additional pelvic lymphadenopathy was identified. Her carcinoembryonic antigen was 1.1, and all other laboratory studies were within normal limits. She was seen in the Colorectal Multidisciplinary Conference for a discussion of her treatment options.


    D. V. Samsonov


    Full Text Available Total mesorectal excision is the “golden standard” of surgical treatment for rectal cancer. Development of endoscopic technologies allowed to implement the benefits of minimally invasive surgery in early rectal cancer treatment, decrease morbidity and mortality, improve functional outcome and quality of life. Oncological safety of this method is still a subject for discussion due to lack of lymph node harvest. Endoscopic operations for early rectal cancer are being actively implemented in daily practice, but lack of experience does not allow to include this method in national clinical prac-tice guidelines.

  9. [Ultrasonographic study of rectal carcinoid tumors].

    To compare intraluminal ultrasonographic (ILUS) findings with histological findings of rectal carcinoid tumors, 35 patients with rectal carcinoid tumors were reviewed. The results were as follows: 1) The rectal wall was visualized as a seven- or nine-layer structure by means of ILUS in 81% of the patients. 2) The possibility that the thin hyperechoic third layer above the tumor on ILUS corresponds to the muscularis mucosae and fibrointerstitium above the tumor histologically. 3) In cases with relatively high internal echoes, the amount of fibrointerstitium exceeded that of tumor cells histologically. 4) In cases with nonuniform internal echo patterns, tumor cells were separated by thick fibrointerstitium forming nodular nests.

  10. Local radiological staging of rectal cancer

    Goh, V.; Halligan, S. E-mail:; Bartram, C.I


    Rectal cancer is a common malignancy with a highly variable outcome. Local recurrence is dependent upon tumour stage and surgical technique. The role of pre-operative imaging is to determine which patients may be safely managed by surgery alone and which need additional therapy in order to facilitate surgery and improve outcome. This decision depends on the distinction between those with early and advanced disease. While trans-rectal ultrasound has traditionally been used to answer this question, a role for magnetic resonance imaging (MRI) is increasingly argued. This review will focus on the treatment options for rectal cancer and the clinical questions that subsequently arise for the radiologist to answer.

  11. Transvaginal ultrasonography of rectal endometriosis

    Egekvist, Anne Gisselmann; Seyer-Hansen, Mikkel; Forman, Axel

    Objectives: The aim of this present study was to evaluate the interobserver variation of transvaginal ultrasonographic measurements of endometriosis infiltrating the rectosigmoid wall. Methods: Transvaginal ultrasonography was performed independently by two observers. Observer 1 had several years...... of experience in ultrasonography while observer 2 was a medical student with no prior experience in ultrasonography or endometriosis. In 24 patient length, width and depth of endometriosis infiltrating the rectosigmoid bowel was measured. The differences between the observers were analysed by Bland and Altman...... for a relatively short period gives comparable scanning results between the two observers. It seems that transvaginal ultrasound could be used as a diagnostic tool for rectal endometriosis in most departments. However, the irregular morphology of the lesions makes the measurements very complex, and a strict...

  16. NPTX2 is associated with neoadjuvant therapy response in rectal cancer.

    Karagkounis, Georgios; Thai, Leo; DeVecchio, Jennifer; Gantt, Gerald A; Duraes, Leonardo; Pai, Rish K; Kalady, Matthew F


    Neoadjuvant chemoradiation (CRT) is recommended for locally advanced rectal cancer. Tumor response varies from pathologic complete response (pCR) to no tumor regression. The mechanisms behind CRT resistance remain undefined. In our previously generated complementary DNA microarrays of pretreatment biopsies from rectal cancer patients, neuronal pentraxin 2 (NPTX2) expression discriminated patients with pCR from those with residual tumor. As tumor response is prognostic for survival, we sought to evaluate the clinical relevance of NPTX2 in rectal cancer. Real-time quantitative polymerase chain reaction was used to evaluate NPTX2 messenger RNA expression in individual rectal cancers before CRT. Tumors with NPTX2 expression 50% were defined as NPTX2-high. NPTX2 levels were compared to response to therapy and oncologic outcomes using Mann-Whitney, Kruskal-Wallis, chi-square, and Mantel-Cox (log-rank) tests, as appropriate. Rectal cancers from 40 patients were included. The mean patient age was 56.8 years, and 30% were female. pCR was achieved in eight of 40 patients (20%). In these patients, messenger RNA NPTX2 levels were significantly decreased compared to those with residual cancer (fold change 30.4, P = 0.017). Patients with NPTX2-low tumors (n = 13) achieved improved response to treatment (P = 0.012 versus NPXT2-high tumors), with 38.5% and 46.1% of patients achieving complete or moderate response, respectively. Of patients with NPTX2-high tumors (n = 27), 11.1% and 18.5% achieved complete or moderate response, respectively. No recurrence or death was recorded in patients with NPTX2-low tumors, reflecting more favorable disease-free survival (P = 0.045). Decreased NPTX2 expression in rectal adenocarcinomas is associated with improved response to CRT and improved prognosis. Further studies to validate these results and elucidate the biological role of NPTX2 in rectal cancer are needed. Copyright © 2016 Elsevier Inc. All rights reserved.

  17. Automatically-generated rectal dose constraints in intensity-modulated radiation therapy for prostate cancer

    Hwang, Taejin; Kim, Yong Nam; Kim, Soo Kon; Kang, Sei-Kwon; Cheong, Kwang-Ho; Park, Soah; Yoon, Jai-Woong; Han, Taejin; Kim, Haeyoung; Lee, Meyeon; Kim, Kyoung-Joo; Bae, Hoonsik; Suh, Tae-Suk


    The dose constraint during prostate intensity-modulated radiation therapy (IMRT) optimization should be patient-specific for better rectum sparing. The aims of this study are to suggest a novel method for automatically generating a patient-specific dose constraint by using an experience-based dose volume histogram (DVH) of the rectum and to evaluate the potential of such a dose constraint qualitatively. The normal tissue complication probabilities (NTCPs) of the rectum with respect to V %ratio in our study were divided into three groups, where V %ratio was defined as the percent ratio of the rectal volume overlapping the planning target volume (PTV) to the rectal volume: (1) the rectal NTCPs in the previous study (clinical data), (2) those statistically generated by using the standard normal distribution (calculated data), and (3) those generated by combining the calculated data and the clinical data (mixed data). In the calculated data, a random number whose mean value was on the fitted curve described in the clinical data and whose standard deviation was 1% was generated by using the `randn' function in the MATLAB program and was used. For each group, we validated whether the probability density function (PDF) of the rectal NTCP could be automatically generated with the density estimation method by using a Gaussian kernel. The results revealed that the rectal NTCP probability increased in proportion to V %ratio , that the predictive rectal NTCP was patient-specific, and that the starting point of IMRT optimization for the given patient might be different. The PDF of the rectal NTCP was obtained automatically for each group except that the smoothness of the probability distribution increased with increasing number of data and with increasing window width. We showed that during the prostate IMRT optimization, the patient-specific dose constraints could be automatically generated and that our method could reduce the IMRT optimization time as well as maintain the

  18. "Enfermedad de las tres mentiras": síndrome de la úlcera rectal solitaria A disease of three lies: solitary rectal ulcer syndrome

    L. Crespo Pérez


    Full Text Available El síndrome de la úlcera rectal solitaria es una entidad benigna poco común cuyos síntomas más frecuentes son la rectorragia y el dolor anal. Los hallazgos anatomopatológicos son típicos. Se suele evidenciar engrosamiento de la mucosa, elongación y distorsión de las glándulas, una lámina propia edematosa con gran cantidad de colágena y engrosamiento de la muscularis mucosae. El diagnóstico se realiza mediante endoscopia con toma de biopsias. No siempre se trata de lesiones ulceradas. Se suele localizar preferentemente en la cara rectal anterior y/o lateral, aunque hasta un 30% de las lesiones son múltiples, existiendo casos de afectación del colon sigmoide y descendente. Por tanto, la presentación puede ser heterogénea y este es el motivo por el que esta entidad es también conocida como la "enfermedad de las tres mentiras". Presentamos un caso de síndrome de la ulcera rectal solitaria manifestado endoscópicamente como una placa eritematosa localizada en la cara lateral izquierda del recto.Solitary rectal ulcer syndrome is an uncommon benign condition characterized by rectal bleeding, passage of mucus, and pain. Histological features are well established as obliteration of the lamina propria by fibrosis and smooth-muscle fibers extending from a thickened muscularis mucosa to the lumen. Diagnosis can usually be made on sigmoidoscopy, and biopsies should always be taken. Ulceration is not universally present, and polypoid, non-ulcerated lesions and erythematous areas are also seen. The lesion or lesions are most often found on the anterior or anterolateral wall of the rectum, although they can also be located in the left colon and be more extensive or even circumferential. Lesions are multiple in 30 percent of cases. These are the reasons why this entity is also known as "the disease of three lies". We report a case of solitary rectal ulcer syndrome presenting at endoscopy with an erythematous area on the left side wall of the

  1. Wind sock deformity in rectal atresia

    Hosseini Seyed


    Full Text Available Rectal atresia is a rare anorectal deformity. It usually presents with neonatal obstruction and it is often a complete membrane or severe stenosis. Windsock deformity has not been reported in rectal atresia especially, having been missed for 2 years. A 2-year-old girl reported only a severe constipation despite having a 1.5-cm anal canal in rectal examination with scanty discharge. She underwent loop colostomy and loopogram, which showed a wind sock deformity of rectum with mega colon. The patient underwent abdominoperineal pull-through with good result and follow-up. This is the first case of the wind sock deformity in rectal atresia being reported after 2 years of age.

  4. Cecal Schwannoma: A Rare Cause of Gastrointestinal Bleeding in a Young Woman with Review of Literature

    Kalyan Kanneganti


    Full Text Available Schwannomas are rare mesenchymal tumors of the gastrointestinal tract. Occurrence of these tumors is more common in the stomach than in the large intestine. These tumors usually present as polypoidal intraluminal lesions and based on their location can present with rectal bleeding, colonic obstruction, and abdominal pain or defecation disorders. We present a case of a thirty-five-year-old woman who presented with abdominal pain and melena. Patient was diagnosed with a nonobstructing superficially ulcerated mass in the cecum on colonoscopy and required right hemicolectomy. A very rare pathological diagnosis of cecal schwannoma was made postoperatively.

  5. Development and Validation of a Stability Indicating RP-HPLC Method for Hydrocortisone Acetate Active Ingredient, Propyl Parahydroxybenzoate and Methyl Parahydroxybenzoate Preservatives, Butylhydroxyanisole Antioxidant, and Their Degradation Products in a Rectal Gel Formulation.

    Ascaso, Magda; Pérez-Lozano, Pilar; García, Mireia; García-Montoya, Encarna; Miñarro, Montse; Ticó, Josep R; Fàbregas, Anna; Carrillo, Carolina; Sarrate, Rocío; Suñé-Negre, Josep M


    A stability indicating method was established through a stress study, wherein different methods of degradation (oxidation, hydrolysis, photolysis, and temperature) were studied simultaneously to determine the active ingredient hydrocortisone acetate, preservatives propyl parahydroxybenzoate, and methyl parahydroxybenzoate, antioxidant butylhydroxyanisole (BHA), and their degradation products in a semisolid dosage gel form. The proposed method was suitably validated using a Zorbax SB-Phenyl column and gradient elution. The mobile phase consisted of a mixture of methanol, acetonitrile, and water in different proportions according to a planned program at a flow rate of 1.5 mL/min. The diode array detector was set at 240 nm for the active substance and two preservatives, and 290 nm for BHA. The validation study was conducted according to International Conference on Harmonization guidelines for specificity, linearity, repeatability, precision, and accuracy. The method was used for QC of hydrocortisone acetate gel and for the stability studies with the aim of quantifying the active substance, preservatives, antioxidant, and degradation products. It has proved to be suitable as a fast and reliable method for QC.

  6. Appendiceal Adenocarcinoma Presenting as a Rectal Polyp

    Erin Fitzgerald


    Full Text Available Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively. The operative strategy had to be adjusted due to this unexpected finding. Although there are published cases of appendiceal adenocarcinoma inducing intussusception and thus mimicking a cecal polyp, there are no reports in the literature describing invasion of the appendix through the rectal wall and thus mimicking a rectal polyp. The patient is a 75-year-old female who presented with spontaneous hematochezia and, on colonoscopy, was noted to have a rectal polyp that appeared to be located within a diverticulum. When endoscopic mucosal resection was not successful, she was referred to colorectal surgery for a low anterior resection. Preoperative imaging was notable for an enlarged appendix adjacent to the rectum. Intraoperatively, the appendix was found to be densely adherent to the right lateral rectal wall. An en bloc resection of the distal sigmoid colon, proximal rectum and appendix was performed, with pathology demonstrating appendiceal adenocarcinoma that invaded through the rectal wall. The prognosis in this type of malignancy weighs heavily on whether or not perforation and spread throughout the peritoneal cavity have occurred. In this unusual presentation, an en bloc resection is required for a complete resection and to minimize the risk of peritoneal spread. Unusual appearing polyps do not always originate from the bowel wall. Abnormal radiographic findings adjacent to an area of

  7. Robotic rectal surgery: State of the art.

    Staderini, Fabio; Foppa, Caterina; Minuzzo, Alessio; Badii, Benedetta; Qirici, Etleva; Trallori, Giacomo; Mallardi, Beatrice; Lami, Gabriele; Macrì, Giuseppe; Bonanomi, Andrea; Bagnoli, Siro; Perigli, Giuliano; Cianchi, Fabio


    Laparoscopic rectal surgery has demonstrated its superiority over the open approach, however it still has some technical limitations that lead to the development of robotic platforms. Nevertheless the literature on this topic is rapidly expanding there is still no consensus about benefits of robotic rectal cancer surgery over the laparoscopic one. For this reason a review of all the literature examining robotic surgery for rectal cancer was performed. Two reviewers independently conducted a search of electronic databases (PubMed and EMBASE) using the key words "rectum", "rectal", "cancer", "laparoscopy", "robot". After the initial screen of 266 articles, 43 papers were selected for review. A total of 3013 patients were included in the review. The most commonly performed intervention was low anterior resection (1450 patients, 48.1%), followed by anterior resections (997 patients, 33%), ultra-low anterior resections (393 patients, 13%) and abdominoperineal resections (173 patients, 5.7%). Robotic rectal surgery seems to offer potential advantages especially in low anterior resections with lower conversions rates and better preservation of the autonomic function. Quality of mesorectum and status of and circumferential resection margins are similar to those obtained with conventional laparoscopy even if robotic rectal surgery is undoubtedly associated with longer operative times. This review demonstrated that robotic rectal surgery is both safe and feasible but there is no evidence of its superiority over laparoscopy in terms of postoperative, clinical outcomes and incidence of complications. In conclusion robotic rectal surgery seems to overcome some of technical limitations of conventional laparoscopic surgery especially for tumors requiring low and ultra-low anterior resections but this technical improvement seems not to provide, until now, any significant clinical advantages to the patients.

  8. Massive lower gastrointestinal bleeding after low anterior resection for middle rectal cancer – case report

    Mircea Beuran


    Conclusions: Angiography with angioembolization is an effective tool in emergency setting, avoiding the morbidity and associated mortality of a surgical reinervention. In early postoperative hemorrhages, only a rapid clinical recognition, a personalized diagnostic workup and an agressive intervention may offer the patient the best chances for cure.

  9. Massive upper gastrointestinal bleed from epiphrenic diverticulum.

    Garcia, Cesar J; Dias, Ajoy; Hejazi, Reza A; Burgos, Jose D; Huerta, Ana; Zuckerman, Marc J


    Epiphrenic diverticula are outpouchings of the esophagus that retain some or all layers of the esophageal wall. Symptoms such as intermittent dysphagia and vomiting may occur. The authors present a case of an elderly woman with a history of dysphagia who presented with a massive upper gastrointestinal bleed because of a bleeding epiphrenic diverticulum seen at endoscopy who responded to conservative management. Bleeding epiphrenic diverticula should be considered as a cause of upper gastrointestinal bleeding.

  10. Abdominal compartment syndrome from bleeding duodenal diverticulum

    Vakhtang Tchantchaleishvili


    Full Text Available Duodenal diverticuli are acquired false diverticuli of unknown etiology. Although mostly asymptomatic, they can occasionally cause upper gastrointestinal hemorrhage, rarely with massive bleeding. In this report, we present (to the best of our knowledge the first reported case of duodenal diverticular bleeding, causing abdominal compartment syndrome. Albeit a rare event, duodenal diverticular bleeding should be included in the differential diagnosis of upper gastrointestinal bleeding. As with our case, a multidisciplinary approach to managing such patients is crucial.

Known common causes of GI bleed include ulcers, varices, Mallory-Weiss among others. All causes of GI bleed should be considered however unusual during the evaluation. Aortoenteric fistula (AEF is one of the unusual causes of GI bleed, which has to be considered especially in patients with a history of abdominal surgery in general and aortic surgery in particular.

  12. Obscure gastrointestinal bleeding: preoperative CT-guided percutaneous needle localization of the bleeding small bowel segment.

    Heiss, Peter; Feuerbach, Stefan; Iesalnieks, Igors; Rockmann, Felix; Wrede, Christian E; Zorger, Niels; Schlitt, Hans J; Schölmerich, Jürgen; Hamer, Okka W


    A 57-year-old woman presented with obscure gastrointestinal bleeding. Double balloon enteroscopy, angiography, and surgery including intraoperative enteroscopy failed to identify the bleeding site. Multidetector computed tomography (CT) depicted active bleeding of a small bowel segment. The bleeding segment was localized by CT-guided percutaneous needle insertion and subsequently removed surgically.

  13. Is urgent CT angiography necessary in cases of acute lower gastrointestinal bleeding?

    Díaz, A Martín; Rodríguez, L Fernández; de Gracia, M Martí


    Acute lower gastrointestinal bleeding usually presents as hematochezia, rectal bleeding or melena and represents 1-2% of the medical appointments in the Emergency Services. Mortality reaches the 30-40% and it is highly related with the severity and associated comorbidity. Most clinical practice guidelines include colonoscopy at some point in the diagnostic and therapeutic process (urgent for severe cases and ambulatory for mild ones) and look for predictors of severity. In the last years, there have been numerous studies where is clear the relevance and complementarity of advanced diagnostic imaging techniques, gradually incorporated as an alternative or second step in severe cases. Therefore, we have made a review of current scientific evidence to establish a clinical prediction rule for optimal indication of CT angiography in these patients. However, future studies providing greater robustness and level of evidence are necessary.

  14. Retroperitoneal Leiomyosarcoma Presenting as Lower Gastrointestinal Bleeding: A Case Report and Review of the Literature

    Dominic G. Ventura


    Full Text Available We report the first known case of a retroperitoneal leiomyosarcoma that presented with an endoscopically defined source of gastrointestinal bleeding in the colon. A 68-year-old male with a history of diverticulosis, hypertension, and hypercholesterolemia who complained of a 3-month history of abdominal pain, nausea, and intermittent hematochezia presented for evaluation of large volume hematochezia and lightheadedness. Colonoscopy revealed left-sided diverticulosis and rectal varices without stigmata of recent bleed. CT scan showed a 26 × 20 × 13 cm heterogeneous retroperitoneal mass and multiple hypodense hepatic lesions. Liver biopsy revealed leiomyosarcoma. In summary, although surgery is the mainstay of treatment, resectability has not improved significantly. Early recognition and aggressive surgery are keys to long-term survival.

  16. The Benefits of Including Clinical Factors in Rectal Normal Tissue Complication Probability Modeling After Radiotherapy for Prostate Cancer

    Defraene, Gilles, E-mail: [Radiation Oncology Department, University Hospitals Leuven, Leuven (Belgium); Van den Bergh, Laura [Radiation Oncology Department, University Hospitals Leuven, Leuven (Belgium); Al-Mamgani, Abrahim [Department of Radiation Oncology, Erasmus Medical Center - Daniel den Hoed Cancer Center, Rotterdam (Netherlands); Haustermans, Karin [Radiation Oncology Department, University Hospitals Leuven, Leuven (Belgium); Heemsbergen, Wilma [Netherlands Cancer Institute - Antoni van Leeuwenhoek Hospital, Amsterdam (Netherlands); Van den Heuvel, Frank [Radiation Oncology Department, University Hospitals Leuven, Leuven (Belgium); Lebesque, Joos V. [Netherlands Cancer Institute - Antoni van Leeuwenhoek Hospital, Amsterdam (Netherlands)


    Purpose: To study the impact of clinical predisposing factors on rectal normal tissue complication probability modeling using the updated results of the Dutch prostate dose-escalation trial. Methods and Materials: Toxicity data of 512 patients (conformally treated to 68 Gy [n = 284] and 78 Gy [n = 228]) with complete follow-up at 3 years after radiotherapy were studied. Scored end points were rectal bleeding, high stool frequency, and fecal incontinence. Two traditional dose-based models (Lyman-Kutcher-Burman (LKB) and Relative Seriality (RS) and a logistic model were fitted using a maximum likelihood approach. Furthermore, these model fits were improved by including the most significant clinical factors. The area under the receiver operating characteristic curve (AUC) was used to compare the discriminating ability of all fits. Results: Including clinical factors significantly increased the predictive power of the models for all end points. In the optimal LKB, RS, and logistic models for rectal bleeding and fecal incontinence, the first significant (p = 0.011-0.013) clinical factor was 'previous abdominal surgery.' As second significant (p = 0.012-0.016) factor, 'cardiac history' was included in all three rectal bleeding fits, whereas including 'diabetes' was significant (p = 0.039-0.048) in fecal incontinence modeling but only in the LKB and logistic models. High stool frequency fits only benefitted significantly (p = 0.003-0.006) from the inclusion of the baseline toxicity score. For all models rectal bleeding fits had the highest AUC (0.77) where it was 0.63 and 0.68 for high stool frequency and fecal incontinence, respectively. LKB and logistic model fits resulted in similar values for the volume parameter. The steepness parameter was somewhat higher in the logistic model, also resulting in a slightly lower D{sub 50}. Anal wall DVHs were used for fecal incontinence, whereas anorectal wall dose best described the other two endpoints

  17. Solitary rectal ulcer syndrome: clinical features, pathophysiology, diagnosis and treatment strategies.

    Zhu, Qing-Chao; Shen, Rong-Rong; Qin, Huan-Long; Wang, Yu


    Solitary rectal ulcer syndrome (SRUS) is an uncommon benign disease, characterized by a combination of symptoms, clinical findings and histological abnormalities. Ulcers are only found in 40% of the patients; 20% of the patients have a solitary ulcer, and the rest of the lesions vary in shape and size, from hyperemic mucosa to broad-based polypoid. Men and women are affected equally, with a small predominance in women. SRUS has also been described in children and in the geriatric population. Clinical features include rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, feeling of incomplete defecation, constipation, and rarely, rectal prolapse. This disease has well-described histopathological features such as obliteration of the lamina propria by fibrosis and smooth muscle fibers extending from a thickened muscularis mucosa to the lumen. Diffuse collage deposition in the lamina propria and abnormal smooth muscle fiber extensions are sensitive markers for differentiating SRUS from other conditions. However, the etiology remains obscure, and the condition is frequently associated with pelvic floor disorders. SRUS is difficult to treat, and various treatment strategies have been advocated, ranging from conservative management to a variety of surgical procedures. The aim of the present review is to summarize the clinical features, pathophysiology, diagnostic methods and treatment strategies associated with SRUS.

    Full Text Available Liyong Xing, Zhifei Liu, Gang Deng, Huan Wang, Yanfeng Zhu, Peng Shi, Bingyue Huo, Yindong Li Department of Urology, Tangshan People’s Hospital, Tangshan, People’s Republic of China Purpose: Xanthogranulomatous prostatitis (XP is a rare form of nonspecific granulomatous prostatitis that can clinically mimic high-grade prostatic carcinoma. It is difficult to diagnose it definitely in clinical settings. Methods: We report a case of XP with prostate-rectal fistula and review the relevant literatures. Result: A 75-year-old man presented with rectal bleeding when he urinated. A locally advanced carcinoma of prostate was suspected initially following the physical, imaging, and hematologic examinations. Subsequently on histopathological and immunohistochemical staining after needle biopsy of the prostate, a diagnosis of XP was made definitely. The patient was catheterized temporarily and treated with tamsulosin and estrogen. The patient underwent uneventful recovery after this conservative therapy. Conclusion: Histologic and immunohistochemical analyses are valuable in differentially diagnosing XP from high-grade prostate carcinoma. Treatment strategy of XP in principle is recommended to be the conservative method. Long-term follow-up earns are highly regarded considering the possibility of coexisting prostate cancer.

    The available dose/volume/outcome data for rectal injury were reviewed. The volume of rectum receiving ≥60Gy is consistently associated with the risk of Grade ≥2 rectal toxicity or rectal bleeding. Parameters for the Lyman-Kutcher-Burman normal tissue complication probability model from four clinical series are remarkably consistent, suggesting that high doses are predominant in determining the risk of toxicity. The best overall estimates (95% confidence interval) of the Lyman-Kutcher-Burman model parameters are n = 0.09 (0.04–0.14); m = 0.13 (0.10–0.17); and TD50 = 76.9 (73.7–80.1) Gy. Most of the models of late radiation toxicity come from three-dimensional conformal radiotherapy dose-escalation studies of early-stage prostate cancer. It is possible that intensity-modulated radiotherapy or proton beam dose distributions require modification of these models because of the inherent differences in low and intermediate dose distributions.

  20. Efficacy of hyperbaric oxygen therapy in patients with radiation-induced rectal ulcers: A report of five cases.

    Yoshimizu, Shoichi; Chino, Akiko; Miyamoto, Yuji; Tagao, Fuyuki; Iwasaki, Susumu; Ide, Daisuke; Tamegai, Yoshiro; Igarashi, Masahiro; Saito, Shoichi; Fujisaki, Junko


    For decades, hyperbaric oxygen therapy has been considered a treatment option in patients with chronic radiation-induced proctitis after pelvic radiation therapy. Refractory cases of chronic radiation-induced proctitis include ulceration, stenosis, and intestinal fistulas with perforation. Appropriate treatment needs to be administered. In this study, we assessed the efficacy of hyperbaric oxygen therapy in five patients with radiation-induced rectal ulcers. Significant improvement and complete ulcer resolution was observed in all treated patients; no side effects were reported. Hyperbaric oxygen therapy has a low toxicity profile and appears to be highly effective in patients with radiation-induced rectal ulcers. However, hyperbaric oxygen therapy alone failed to improve telangiectasia and easy bleeding in four of five patients; these patients were further treated with argon plasma coagulation. Although hyperbaric oxygen therapy may be effective in healing patients with ulcers, it seems inadequate in cases that easy bleeding. Altogether, these data suggest that combination therapy with hyperbaric oxygen therapy and argon plasma coagulation may be an effective and safe treatment strategy in patients with radiation-induced rectal ulcers.

  1. Role of videocapsule endoscopy for gastrointestinal bleeding

    Cristina Carretero; Ignacio Fernandez-Urien; Maite Betes; Miguel Mu(n)oz-Navas


    Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of an unknown origin that persists or recurs after negative initial upper and lower endoscopies.Several techniques,such as endoscopy,arteriography,scintigraphy and barium radiology are helpful for recognizing the bleeding source;nevertheless,in about 5%-10% of cases the bleeding lesion cannot be determined.The development of videocapsule endoscopy (VCE) has permitted a direct visualization of the small intestine mucosa.We will analyze those techniques in more detail.The diagnostic yield of CE for OGIB varies from 38% to 93%,being in the higher range in those cases with obscure-overt bleeding.

  2. Identification of capsaicin-sensitive rectal mechanoreceptors activated by rectal distension in mice.

    Spencer, N J; Kerrin, A; Singer, C A; Hennig, G W; Gerthoffer, W T; McDonnell, O


    Rodents detect visceral pain in response to noxious levels of rectal distension. However, the mechanoreceptors that innervate the rectum and respond to noxious levels of rectal distension have not been identified. Here, we have identified the mechanoreceptors of capsaicin-sensitive rectal afferents and characterized their properties in response to circumferential stretch of the rectal wall. We have also used the lethal spotted (ls/ls) mouse to determine whether rectal mechanoreceptors that respond to capsaicin and stretch may also develop in an aganglionic rectum that is congenitally devoid of enteric ganglia. In wild type (C57BL/6) mice, graded increases in circumferential stretch applied to isolated rectal segments activated a graded increase in firing of slowly-adapting rectal mechanoreceptors. Identical stimuli applied to the aganglionic rectum of ls/ls mice also activated similar graded increases in firing of stretch-sensitive rectal afferents. In both wild type and aganglionic rectal preparations, focal compression of the serosal surface using von Frey hairs identified mechanosensitive "hot spots," that were associated with brief bursts of action potentials. Spritzing capsaicin (10 microM) selectively onto each identified mechanosensitive hot spot activated an all or none discharge of action potentials in 32 of 56 identified hot spots in wild type mice and 24 of 62 mechanosensitive hot spots in the aganglionic rectum of ls/ls mice. Each single unit activated by both capsaicin and circumferential stretch responded to low mechanical thresholds (1-2 g stretch). No high threshold rectal afferents were ever recorded in response to circumferential stretch. Anterograde labeling from recorded rectal afferents revealed two populations of capsaicin-sensitive mechanoreceptor that responded to stretch: one population terminated within myenteric ganglia, the other within the circular and longitudinal smooth muscle layers. In the aganglionic rectum of ls/ls mice, only the

  3. Locally advanced rectal cancer: management challenges

    Kokelaar RF


    Full Text Available RF Kokelaar, MD Evans, M Davies, DA Harris, J Beynon Department of Colorectal Surgery, Singleton Hospital, Swansea, UK Abstract: Between 5% and 10% of patients with rectal cancer present with locally advanced rectal cancer (LARC, and 10% of rectal cancers recur after surgery, of which half are limited to locoregional disease only (locally recurrent rectal cancer. Exenterative surgery offers the best long-term outcomes for patients with LARC and locally recurrent rectal cancer so long as a complete (R0 resection is achieved. Accurate preoperative multimodal staging is crucial in assessing the potential operability of advanced rectal tumors, and resectability may be enhanced with neoadjuvant therapies. Unfortunately, surgical options are limited when the tumor involves the lateral pelvic sidewall or high sacrum due to the technical challenges of achieving histological clearance, and must be balanced against the high morbidity associated with resection of the bony pelvis and significant lymphovascular structures. This group of patients is usually treated palliatively and subsequently survival is poor, which has led surgeons to seek innovative new solutions, as well as revisit previously discarded radical approaches. A small number of centers are pioneering new techniques for resection of beyond-total mesorectal excision tumors, including en bloc resections of the sciatic notch and composite resections of the first two sacral vertebrae. Despite limited experience, these new techniques offer the potential for radical treatment of previously inoperable tumors. This narrative review sets out the challenges facing the management of LARCs and discusses evolving management options. Keywords: rectal cancer, exenteration, pelvic sidewall, sacrectomy

    Neunert, C; Noroozi, N; Norman, G; Buchanan, G R; Goy, J; Nazi, I; Kelton, J G; Arnold, D M


    The burden of severe bleeding in adults and children with immune thrombocytopenia (ITP) has not been established. To describe the frequency and severity of bleeding events in patients with ITP, and the methods used to measure bleeding in ITP studies. We performed a systematic review of all prospective ITP studies that enrolled 20 or more patients. Two reviewers searched Medline, Embase, CINAHL and the Cochrane registry up to May 2014. Overall weighted proportions were estimated using a random effects model. Measurement properties of bleeding assessment tools were evaluated. We identified 118 studies that reported bleeding (n = 10 908 patients). Weighted proportions for intracerebral hemorrhage (ICH) were 1.4% for adults (95% confidence interval [CI], 0.9-2.1%) and 0.4% for children (95% CI, 0.2-0.7%; P bleeding was 9.6% for adults (95% CI, 4.1-17.1%) and 20.2% for children (95% CI, 10.0-32.9%; P bleeding were highly variable in primary studies. Two bleeding assessment tools (Buchanan 2002 for children; Page 2007 for adults) demonstrated adequate inter-rater reliability and validity in independent assessments. ICH was more common in adults and tended to occur during chronic ITP; other severe bleeds were more common in children and occurred at all stages of disease. Reporting of non-ICH bleeding was variable across studies. Further attention to ITP-specific bleeding measurement in clinical trials is needed to improve standardization of this important outcome for patients. © 2014 International Society on Thrombosis and Haemostasis.

  5. [Antithrombotic therapy and nonvariceal upper gastrointestinal bleeding].

    Belanová, Veronika; Gřiva, Martin


    The incidence of acute upper gastrointestinal bleeding is about 85-108/100,000 inhabitants per year, nonvariceal bleeding accounts for 80-90%. Antiplatelet and anticoagulation treatment are the significant risk factors for upper gastrointestinal bleeding. To evaluate the occurrence of upper gastrointestinal bleeding in the general community of patients in a county hospital. And to compare the role played by antiplatelet and anticoagulation drugs and other risk medication. Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobinupper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobingastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even

    Management of antithrombotic therapy in elderly patients with unstable atherothrombotic disease and increased risk of bleeding is a major clinical challenge. We report the case of a 79 year- old diabetic man with rheumatoid arthritis on both oral corticosteroids and NSAID therapy with mild renal dysfunction, who presented to our hospital because of disabling claudication. Prior to admission he had several episodes of TIA. He also had recurrent small rectal bleeding and mild anemia attributed to his long-standing hemorrhoid disease. Angiography showed a sub-occlusive left internal carotid artery stenosis associated with a significant LAD stenosis and complex peripheral artery disease. Cataclysmic bleeding and hemorrhagic shock occurred in the third day post admission. Withdrawal of all antithrombotic treatment, blood transfusion and emergency sigmoidectomy were performed for bleeding colonic diverticulosis. Subsequently antiplatelet therapy was reinitiated and the patient successfully underwent left carotid artery endarterectomy and LAD stenting. He was discharged from hospital on the 21(st) day post admission and is doing well at 24 months follow-up.

  8. Platelet Function Tests in Bleeding Disorders.

    Lassila, Riitta


    Functional disorders of platelets can involve any aspect of platelet physiology, with many different effects or outcomes. These include platelet numbers (thrombocytosis or thrombocytopenia); changes in platelet production or destruction, or capture to the liver (Ashwell receptor); altered adhesion to vascular injury sites and/or influence on hemostasis and wound healing; and altered activation or receptor functions, shape change, spreading and release reactions, procoagulant and antifibrinolytic activity. Procoagulant membrane alterations, and generation of thrombin and fibrin, also affect platelet aggregation. The above parameters can all be studied, but standardization and quality control of assay methods have been limited despite several efforts. Only after a comprehensive clinical bleeding assessment, including family history, information on drug use affecting platelets, and exclusion of coagulation factor, and tissue deficits, should platelet function testing be undertaken to confirm an abnormality. Current diagnostic tools include blood cell counts, platelet characteristics according to the cell counter parameters, peripheral blood smear, exclusion of pseudothrombocytopenia, whole blood aggregometry (WBA) or light transmission aggregometry (LTA) in platelet-rich plasma, luminescence, platelet function analysis (PFA-100) for platelet adhesion and deposition to collagen cartridges under blood flow, and finally transmission electron microscopy to exclude rare structural defects leading to functional deficits. The most validated test panels are included in WBA, LTA, and PFA. Because platelets are isolated from their natural environment, many simplifications occur, as circulating blood and interaction with vascular wall are omitted in these assays. The target to reach a highly specific platelet disorder diagnosis in routine clinical management can be exhaustive, unless needed for genetic counseling. The elective overall assessment of platelet function disorder

  9. Tranexamic Acid in the Management of Upper Gastrointestinal Bleeding: an Evidence-based Case Report

    Nur Atikah


    Full Text Available Aim: to review the effectiveness of tranexamic acid therapy which has been proposed to reduce bleeding and in turn lower mortality rate. Methods: following literature searching based on our clinical question on Cochrane Library, PubMed, Clinical Key, EBSCO, Science Direct and Proquest, one systematic review that includes seven randomized controlled trials is obtained. The article meets validity and relevance criteria. Results: the systematic review found that there is no any clear evidence between intervention and control groups in term of mortality. Conclusion: the use of tranexamic acid to reduce mortality in patients with upper gastrointestinal bleeding is not recommended. Key words: tranexamic acid, mortality, upper gastrointestinal bleeding.

  10. Preoperative staging of rectal cancer.

    Smith, Neil; Brown, Gina


    Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR assessment of prognostic factors prior to therapy has been found to be of value in assessing treatment modalities and outcomes that are targeted to these preoperative prognostic subgroups and in providing a quantifiable assessment of the efficacy of particular chemoradiation treatment protocols by comparing pre-treatment MR staging with post therapy histology assessment. At present, we are focused on achieving clear surgical margins of excision (CRM) to avoid local recurrence. We recommend that all patients with rectal cancer should undergo pre-operative MRI staging. Of these, about half will have good prognosis features (T1-T3b, N0, EMVI negative, CRM clear) and may safely undergo primary total mesorectal excision. Of the remainder, those with threatened or involved margins will certainly benefit from pre-operative chemoradiotherapy with the aim of downstaging to permit safe surgical excision. In the future, our ability to recognise features predicting distant failure, such as extramural vascular invasion (EMVI) may be used to stratify patients for neo-adjuvant systemic chemotherapy in an effort to prevent distant relapse. The optimal pre-operative treatment regimes for these patients (radiotherapy alone, systemic chemotherapy alone or combination chemo-radiotherapy) is the subject of current and future trials.

  11. The management of lower gastrointestinal bleeding.

    Marion, Y; Lebreton, G; Le Pennec, V; Hourna, E; Viennot, S; Alves, A


    Lower gastrointestinal (LGI) bleeding is generally less severe than upper gastrointestinal (UGI) bleeding with spontaneous cessation of bleeding in 80% of cases and a mortality of 2-4%. However, unlike UGI bleeding, there is no consensual agreement about management. Once the patient has been stabilized, the main objective and greatest difficulty is to identify the location of bleeding in order to provide specific appropriate treatment. While upper endoscopy and colonoscopy remain the essential first-line examinations, the development and availability of angiography have made this an important imaging modality for cases of active bleeding; they allow diagnostic localization of bleeding and guide subsequent therapy, whether therapeutic embolization, interventional colonoscopy or, if other techniques fail or are unavailable, surgery directed at the precise site of bleeding. Furthermore, newly developed endoscopic techniques, particularly video capsule enteroscopy, now allow minimally invasive exploration of the small intestine; if this is positive, it will guide subsequent assisted enteroscopy or surgery. Other small bowel imaging techniques include enteroclysis by CT or magnetic resonance imaging. At the present time, exploratory surgery is no longer a first-line approach. In view of the lesser gravity of LGI bleeding, it is most reasonable to simply stabilize the patient initially for subsequent transfer to a specialized center, if minimally invasive techniques are not available at the local hospital. In all cases, the complexity and diversity of LGI bleeding require a multidisciplinary collaboration involving the gastroenterologist, radiologist, intensivist and surgeon to optimize diagnosis and treatment of the patient.

  14. Critical analysis of the literature investigating urogenital function preservation following robotic rectal cancer surgery.

    Panteleimonitis, Sofoklis; Ahmed, Jamil; Harper, Mick; Parvaiz, Amjad


    To analyses the current literature regarding the urogenital functional outcomes of patients receiving robotic rectal cancer surgery. A comprehensive literature search of electronic databases was performed in October 2015. The following search terms were applied: "rectal cancer" or "colorectal cancer" and robot* or "da Vinci" and sexual or urolog* or urinary or erect* or ejaculat* or impot* or incontinence. All original studies examining the urological and/or sexual outcomes of male and/or female patients receiving robotic rectal cancer surgery were included. Reference lists of all retrieved articles were manually searched for further relevant articles. Abstracts were independently searched by two authors. Fifteen original studies fulfilled the inclusion criteria. A total of 1338 patients were included; 818 received robotic, 498 laparoscopic and 22 open rectal cancer surgery. Only 726 (54%) patients had their urogenital function assessed via means of validated functional questionnaires. From the included studies, three found that robotic rectal cancer surgery leads to quicker recovery of male urological function and five of male sexual function as compared to laparoscopic surgery. It is unclear whether robotic surgery offers favourable urogenital outcomes in the long run for males. In female patients only two studies assessed urological and three sexual function independently to that of males. In these studies there was no difference identified between patients receiving robotic and laparoscopic rectal cancer surgery. However, in females the presented evidence was very limited making it impossible to draw any substantial conclusions. There seems to be a trend towards earlier recovery of male urogenital function following robotic surgery. To evaluate this further, larger well designed studies are required.

  15. Rectal cancer treatment: Improving the picture


    Multidisciplinary approach for rectal cancer treatment is currently well defined. Nevertheless, new and promising advances are enriching the portrait. Since the US NIH Consensus in the early 90's some new characters have been added. A bird's-eye view along the last decade shows the main milestones in the development of rectal cancer treatment protocols. New drugs, in combination with radiotherapy are being tested to increase response and tumor control outcomes. However, therapeutic intensity is often associated with toxicity. Thus, innovative strategies are needed to create a better-balanced therapeutic ratio. Molecular targeted therapies and improved technology for delivering radiotherapy respond to the need for accuracy and precision in rectal cancer treatment.

  16. MRI Findings of Rectal Submucosal Tumors

    Kim, Hon Soul; Kim, Joo Hee; Lim, Joon Seok; Choi, Jin Young; Chung, Yong Eun; Park, Mi Suk; Kim, Myeong Jin; Kim, Ki Whang; Kim, Sang Kyum [Yonsei University Health System, Seoul (Korea, Republic of)


    Rectal submucosal lesions encompass a wide variety of benign and malignant tumors involving the rectum. With optical colonoscopy, any mass-like protrusion covered by normal mucosa, whether the underlying process is intramural or extramural in origin, may be reported as a submucosal lesion. Whereas the assessment of submucosal lesions may be limited with performing optical colonoscopy, cross-sectional imaging such as CT, transrectal ultrasonography and MRI allows the evaluation of perirectal tissues and pelvic organs in addition to the entire thickness of the rectum, and so this is advantageous for the assessment of rectal submucosal tumors. Among these, MRI is the best investigative modality for soft tissue characterization. Therefore, knowledge of the MRI features of rectal submucosal tumors can help achieve accurate preoperative diagnoses and facilitate the appropriate management.

  17. Masquerading Mycobacterium: Rectal Growth or Tuberculosis?

    Nabajit Choudhury


    Full Text Available A 37-year old male presented to us with history of lower abdominal pain for 6 months. His physical examination revealed a rectal mass of approximately 1centimeter. He was investigated for possible rectal growth with sigmoidoscopy and biopsy. The histopathological examination (HPE showed a non-specific chronic inflammation in the tissue from the mass. Another tissue from the mass was sent for polymerase chain reaction (PCR for tuberculosis, which turned out to be positive. The patient was started on standard anti tubercular (ATT regimen and responded completely to the treatment. We discuss the patient and review some of the available literature on the topic and discuss the issue of considering a diagnosis of tuberculosis in cases with rectal mass specially when it has become a major public health issue with increasing number of HIV (Human Immunodeficiency Virus infected patients.

    Nygaard, Hanne; Maschmann, Christian Peter

    equipment for measuring body temperature is necessary. Various non-invasive and easily used digital thermometers are available including the Temporal Artery Thermometer (TAT). However, there is lack of evidence for using the TAT-measurement as an accurate non-invasive method for measuring body temperature....... Methods: We designed a prospective comparative study of body temperature measurements using the TAT (Exergen TAT-5000 fra Exergen Corporation, Watertown, Massachusett) and a conventional digital rectal thermometer (Omron MC-341-E, OMRON healtcare Europe B.V., Hoofddroop, Holland), respectively...... and negative predictive value was 63.2% (CI: 46.0–78.2) and 96.5% (CL: 94.0–98.2), respectively. Conclusions: The study showed inacceptable wide temperature deviation between measurements performed with the TAT compared with the rectal measurements being performed with a conventional rectal thermometer...

  19. The Great Pretender: Rectal Syphilis Mimic a Cancer

    Andrea Pisani Ceretti


    Full Text Available Rectal syphilis is a rare expression of the widely recognised sexual transmitted disease, also known as the great imitator for its peculiarity of being confused with mild anorectal diseases because of its vague symptoms or believed rectal malignancy, with the concrete risk of overtreatment. We present the case of a male patient with primary rectal syphilis, firstly diagnosed as rectal cancer; the medical, radiological, and endoscopic features are discussed below.

  2. [Adjuvant chemotherapy for patients with rectal cancer].

    Qvortrup, Camilla; Mortensen, John Pløen; Pfeiffer, Per


    A new Cochrane meta-analysis evaluated adjuvant chemotherapy (5-fluorouracil (5FU)-based, not modern combination chemotherapy) in almost 10,000 patients with rectal cancer and showed a 17% reduction in mortality corresponding well to the efficacy observed in recent studies, which reported a reduction in mortality just about 20%. The authors recommend adjuvant chemotherapy which is in accordance with the Danish national guidelines where 5-FU-based chemotherapy is recommended for stage III and high-risk stage II rectal cancer.

  3. Massive zosteriform cutaneous metastasis from rectal carcinoma.

    Damin, D C; Lazzaron, A R; Tarta, C; Cartel, A; Rosito, M A


    A 44-year-old man presented with a large and rapidly growing skin lesion approximately six months after resection of a rectal carcinoma. The lesion measured 40 cm in size, extended from the suprapubic area to the proximal half of the left groin, and showed a particular zosteriform aspect. Biopsy confirmed a metastatic skin adenocarcinoma. Cutaneous metastases from rectal cancer are very uncommon. Their gross appearance is not distinctive, although the skin tumors are usually solid, small (less than 5 cm) and painless nodules or papules. Early biopsies for suspicious skin lesions are needed in patients with a history of colorectal cancer.

  4. Postmenopausal Vaginal Bleeding after Infesting with Leeches

    Roghaieh Rahmani-Bilandi


    Full Text Available Diagnosis and therapeutic measures are immediately taken for abnormal postmenopausal vaginal bleeding, because its causes range from atrophic endometrium to malignancy. In this paper, abnormal bleeding is reported due to leech infection. The patient is a 69-year-old woman who has reached menopause for 12 years and has visited a physician because of vaginal bleeding. The patient had no history of abnormal bleeding or medication. The patient first refused to get hospitalized and continue medical care, but she finally accepted to take diagnostic and therapeutic procedures after a few times of visit and increased bleeding. During general anesthesia and upon opening vagina, a large hemorrhagic and moving mass was observed at the upper posterior vaginal wall which was removed with surgical forceps. Surprisingly, this mass was a leech. Bleeding at the leech’s junction was stopped after half an hour using sterile gas and the patient was discharged on the next day.

  5. Not Just Painless Bleeding: Meckel’s Diverticulum as a Cause of Small Bowel Obstruction in Children—Two Cases and a Review of the Literature

    Khalida Itriyeva


    Full Text Available Physicians are educated with the classical teaching that symptomatic patients with Meckel’s diverticulum (MD most often present with painless rectal bleeding. However, a review of the literature reveals that young patients with MD will most commonly present with signs of intestinal obstruction, an etiology not frequency considered in patients presenting to the emergency department with obstruction. We present two cases of intestinal obstruction diagnosed in our emergency department, with Meckel’s diverticulum being the etiology.

  6. Trouble with bleeding: risk factors for acute hepatitis C among HIV-positive gay men from Germany--a case-control study.

    Axel J Schmidt

    Full Text Available OBJECTIVES: To identify risk factors for hepatitis C among HIV-positive men who have sex with men (MSM, focusing on potential sexual, nosocomial, and other non-sexual determinants. BACKGROUND: Outbreaks of hepatitis C virus (HCV infections among HIV-positive MSM have been reported by clinicians in post-industrialized countries since 2000. The sexual acquisition of HCV by gay men who are HIV positive is not, however, fully understood. METHODS: Between 2006 and 2008, a case-control study was embedded into a behavioural survey of MSM in Germany. Cases were HIV-positive and acutely HCV-co-infected, with no history of injection drug use. HIV-positive MSM without known HCV infection, matched for age group, served as controls. The HCV-serostatus of controls was assessed by serological testing of dried blood specimens. Univariable and multivariable regression analyses were used to identify factors independently associated with HCV-co-infection. RESULTS: 34 cases and 67 controls were included. Sex-associated rectal bleeding, receptive fisting and snorting cocaine/amphetamines, combined with group sex, were independently associated with case status. Among cases, surgical interventions overlapped with sex-associated rectal bleeding. CONCLUSIONS: Sexual practices leading to rectal bleeding, and snorting drugs in settings of increased HCV-prevalence are risk factors for acute hepatitis C. We suggest that sharing snorting equipment as well as sharing sexual partners might be modes of sexual transmission. Condoms and gloves may not provide adequate protection if they are contaminated with blood. Public health interventions for HIV-positive gay men should address the role of blood in sexual risk behaviour. Further research is needed into the interplay of proctosurgery and sex-associated rectal bleeding.

  7. Upper gastrointestinal bleeding in patients with CKD.

    Liang, Chih-Chia; Wang, Su-Ming; Kuo, Huey-Liang; Chang, Chiz-Tzung; Liu, Jiung-Hsiun; Lin, Hsin-Hung; Wang, I-Kuan; Yang, Ya-Fei; Lu, Yueh-Ju; Chou, Che-Yi; Huang, Chiu-Ching


    Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR. A history of upper gastrointestinal bleeding (Pupper gastrointestinal bleeding risk. In patients with CKD who are not receiving dialysis, lower renal function is associated with higher risk for upper gastrointestinal bleeding. The risk is higher in patients with previous upper gastrointestinal bleeding history and low serum albumin. Copyright © 2014 by the American Society of Nephrology.

  8. Gastric ulcer bleeding: diagnosis by computed tomography

    Voloudaki, Argyro; Tsagaraki, Kaliopi; Mouzas, John; Gourtsoyiannis, Nickolas


    A case of CT demonstration of a bleeding gastric ulcer is presented, in a patient with confusing clinical manifestations. Abdominal CT was performed without oral contrast medium administration, and showed extravasation of intravenous contrast into a gastric lumen distended with material of mixed attenuation. It is postulated that if radiopaque oral contrast had been given, peptic ulcer bleeding would probably have been masked. CT demonstration of gastric ulcer bleeding, may be of value in cases of differential diagnostic dilemmas.

  11. An Unusual Appearance of Meckel's Diverticulum as a Site of Bleed on Gastrointestinal Bleeding Scan

    Mahajan, Madhuri Shimpi


    Lower gastrointestinal (GI) hemorrhage is a frequently encountered and challenging clinical problem. GI bleeding scans are extremely useful for localizing the source of GI bleeding before interventional radiology procedures. It is essential that physicians understand the numerous possible pitfalls when interpreting these scans. Understanding the potential causes of false-positive scan interpretation eliminates unnecessary procedures for the patient and minimizes costs. We report a rare case of an 8-year-old boy who presented with GI bleeding. Upper and lower GI endoscopy did not reveal a source of bleeding. We emphasize case of Meckel's diverticulum appearing as a proximal jejunum false-positive site of bleed on bleeding scan. In addition, we reinforce the criteria needed for diagnosis of GI bleeding site on the nuclear bleeding scan. A high index of suspicion is the most important diagnostic aid that can prevent the nuclear medicine physicians from misdiagnosing the site of lower GI hemorrhage. PMID:25165421

  12. Urogenital and Rectal Multisystem Organ Injury After Detonation of an Explosive Substance in the Rectum of a Schizophrenic Man

    Ali E. Zumrutbas


    Full Text Available Penetrating injuries are caused by the injury of perineal area with gun or stab wounds, which may cause complex injuries or multiple organ injuries. Infections, bleeding, necrotizing fasciitis, ureterocutaneous fistulas, diverticulum, abscesses, narrowing, and incontinence may arise after urethral injuries. Although there are several case reports of urogenital system traumas in the literature, this case reports a schizophrenic patient who had a multisystem genitourinary and rectal trauma after self-detonation of an explosive in the rectum and managed with reconstructive surgery without any postoperative complications. Lower urinary tract anatomy was preserved and full continence was achieved after the surgical procedure.

  13. Provocative Endoscopy to Identify Bleeding Site in Upper Gastrointestinal Bleeding: A Novel Approach in Transarterial Embolization.

    Kamo, Minobu; Fuwa, Sokun; Fukuda, Katsuyuki; Fujita, Yoshiyuki; Kurihara, Yasuyuki


    This report describes a novel approach to endoscopically induce bleeding by removing a clot from the bleeding site during angiography for upper gastrointestinal (UGI) hemorrhage. This procedure enabled accurate identification of the bleeding site, allowing for successful targeted embolization despite a negative initial angiogram. Provocative endoscopy may be a feasible and useful option for angiography of obscure bleeding sites in patients with UGI arterial hemorrhage. Copyright © 2016 SIR. Published by Elsevier Inc.

  18. [Rectal cancer: diagnosis, screening and treatment].

    Decanini-Terán, César Oscar; González-Acosta, Jorge; Obregón-Méndez, Jorge; Vega-de Jesús, Martín


    Rectal cancer is one of the primary malignant neoplasms occurring in Mexican patients of reproductive age. Unfortunately, randomized studies in rectal cancer do not exist as they do with well-recognized colon cancer. We must individualize the epidemiology, risk factors, diagnostic approach, staging and treatment because management is different in rectal cancers affecting the mid- and lower third of the rectum than in the upper third and in colon cancers. Histological staging is the primary prognostic factor. TNM staging (tumor, node, and metastasis) is used internationally by the American Joint Committee on Cancer (AJCC). Staging is done with the assistance of endorectal ultrasound, which is best used in early-stage cancer; however, there are certain disadvantages in detecting node involvement. Magnetic resonance, on the other hand, allows for the evaluation of stenotic tumors and node involvement. Once the correct diagnosis and staging have been made, the next step is correct treatment. Neoadjuvant treatment has demonstrated to be better than adjuvant treatment. Abdominoperineal resection is rarely practiced currently, with sphincter preservation being the preferred procedure. Laparoscopic approach has conferred the advantages of the approach itself when performed by experts in the procedure but there is insufficient evidence to make it the "gold standard." Rectal cancer is a complex pathology that must be considered totally different from colon cancer for diagnosis and treatment. The patient must be staged completely and appropriately for individualizing correct treatment. More long-term studies are needed for optimizing treatment modalities.

  1. Combined radical retropubic prostatectomy and rectal resection.

    Klee, L W; Grmoljez, P


    To present our experience with a small series of men who underwent simultaneous radical retropubic prostatectomy and rectal resection. Three men with newly diagnosed prostate cancer were found to have concurrent rectal tumors requiring resection. All three men underwent non-nerve-sparing radical retropubic prostatectomy and abdominoperineal resection (APR) or low anterior resection (LAR) of the rectum at the same operation. In the 2 patients undergoing APR, the levators were approximated posterior to the urethra, and the bladder was secured to the pubis. The patient undergoing LAR had urinary diversion stents placed and a diverting transverse loop colostomy. All 3 patients had excellent return of urinary continence. One patient required reoperation in the early postoperative period for small bowel adhesiolysis and stoma revision. Another patient had a mild rectal anastomotic stricture and a bladder neck stricture; both were successfully treated with a single dilation. No other significant complications occurred in these patients. Radical retropubic prostatectomy can safely be performed with partial or complete rectal resection in a single operation. A few minor modifications of the standard radical retropubic prostatectomy in this setting are suggested.

  2. Rectal Toxicity After Proton Therapy For Prostate Cancer: An Analysis of Outcomes of Prospective Studies Conducted at the University of Florida Proton Therapy Institute

    Colaco, Rovel J.; Hoppe, Bradford S.; Flampouri, Stella [The University of Florida Proton Therapy Institute, Jacksonville, Florida (United States); McKibben, Brian T. [Baptist Health Medical Center, Department of Surgery, Jacksonville, Florida (United States); Henderson, Randal H.; Bryant, Curtis; Nichols, Romaine C.; Mendenhall, William M.; Li, Zuofeng; Su, Zhong [The University of Florida Proton Therapy Institute, Jacksonville, Florida (United States); Morris, Christopher G. [Baptist Health Medical Center, Department of Surgery, Jacksonville, Florida (United States); Mendenhall, Nancy P., E-mail: [The University of Florida Proton Therapy Institute, Jacksonville, Florida (United States)


    Purpose: Study goals were to characterize gastrointestinal effects of proton therapy (PT) in a large cohort of patients treated for prostate cancer, identify factors associated with rectal bleeding (RB), and compare RB between patients receiving investigational protocols versus those in outcome-tracking protocols. Methods and Materials: A total of 1285 consecutive patients were treated with PT between August 2006 and May 2010. Potential pre-existing clinical and treatment-related risk factors for rectal toxicity were recorded. Common Terminology Criteria for Adverse Events version 3.0 was used to score toxicity. Results: Transient RB was the predominant grade 2 or higher (GR2+) toxicity after PT, accounting for 95% of gastrointestinal events. GR1 RB occurred in 217 patients (16.9%), GR2 RB in 187 patients (14.5%), and GR3 in 11 (0.9%) patients. There were no GR4 or GR5 events. Univariate analyses showed correlations between GR2+ RB and anticoagulation therapy (P=.008) and rectal and rectal wall dose-volume histogram (DVH) parameters (P<.001). On multivariate analysis, anticoagulation therapy (P=.0034), relative volume of rectum receiving 75 Gy (V75; P=.0102), and relative rectal wall V75 (P=.0017) were significant predictors for G2+ RB. Patients treated with investigational protocols had toxicity rates similar to those receiving outcome-tracking protocols. Conclusions: PT was associated with a low rate of GR2+ gastrointestinal toxicity, predominantly transient RB, which was highly correlated with anticoagulation and rectal DVH parameters. Techniques that limit rectal exposure should be used when possible.

  3. Factors Associated With Major Bleeding Events

    Goodman, Shaun G.; Wojdyla, Daniel M.; Piccini, Jonathan P.; White, Harvey D.; Paolini, John F.; Nessel, Christopher C.; Berkowitz, Scott D.; Mahaffey, Kenneth W.; Patel, Manesh R.; Sherwood, Matthew W.; Becker, Richard C.; Halperin, Jonathan L.; Hacke, Werner; Singer, Daniel E.; Hankey, Graeme J.; Breithardt, Gunter; Fox, Keith A. A.; Califf, Robert M.


    Objectives This study sought to report additional safety results from the ROCKET AF (Rivaroxaban Once-daily oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation). Background The ROCKET AF trial demonstrated similar risks of stroke/systemic embolism and major/nonmajor clinically relevant bleeding (principal safety endpoint) with rivaroxaban and warfarin. Methods The risk of the principal safety and component bleeding endpoints with rivaroxaban versus warfarin were compared, and factors associated with major bleeding were examined in a multivariable model. Results The principal safety endpoint was similar in the rivaroxaban and warfarin groups (14.9 vs. 14.5 events/100 patient-years; hazard ratio: 1.03; 95% confidence interval: 0.96 to 1.11). Major bleeding risk increased with age, but there were no differences between treatments in each age category (<65, 65 to 74, ≥75 years; pinteraction = 0.59). Compared with those without (n = 13,455), patients with a major bleed (n = 781) were more likely to be older, current/prior smokers, have prior gastrointestinal (GI) bleeding, mild anemia, and a lower calculated creatinine clearance and less likely to be female or have a prior stroke/transient ischemic attack. Increasing age, baseline diastolic blood pressure (DBP) ≥90 mm Hg, history of chronic obstructive pulmonary disease or GI bleeding, prior acetylsalicylic acid use, and anemia were independently associated with major bleeding risk; female sex and DBP <90 mm Hg were associated with a decreased risk. Conclusions Rivaroxaban and warfarin had similar risk for major/nonmajor clinically relevant bleeding. Age, sex, DBP, prior GI bleeding, prior acetylsalicylic acid use, and anemia were associated with the risk of major bleeding.

  5. Numerical and experimental investigation of a centrifugal compressor with an inducer casing bleed system

    Hunziker, R.; Dickmann, H.P. [ABB Turbo Systems, Baden (Switzerland); Emmrich, R. [RWTH Aachen (Germany)


    State-of-the-art centrifugal compressors for turbocharger applications are required to provide broad compressor maps, high pressure ratios and high efficiency levels. Usually these requirements are perceived as contradictory and represent challenging design targets. Various techniques for map width enhancements have been reported since the early 1980s. ABB Turbo Systems Limited has adopted a simple bleed system for internal flow recirculation to a high flowrate, high efficiency, pressure ratio 4.2 centrifugal compressor stage. After initial test runs had proved the effectiveness of the bleed system, computational fluid dynamics (CFD) calculations were performed in order to gain insight into the flow pattern in both the compressor stage and the bleed system. The simulations explain the effectiveness by comparing them with simulations without the bleed channel. Selected streamline and iso-surface plots show the effect of the bleed channel flow on the main flow through the impeller. Four more variants of bleed channels have been modelled and investigated by CFD In order to optimize the bleed slot location and dimension. The most promising configuration, which showed a significant improvement in map width without a loss in efficiency, was subsequently built and tested. This test confirmed the validity of the CFD simulation results. (author)

  6. Rectal cancer radiotherapy: Towards European consensus

    Valentini, Vincenzo (Cattedra di Radioterapia, Univ. Cattolica S.Cuore, Rome (Italy)), E-mail:; Glimelius, Bengt (Dept. of Oncology, Radiology and Clinical Immunology, Uppsala Univ., Uppsala (Sweden))


    Background and purpose. During the first decade of the 21st century several important European randomized studies in rectal cancer have been published. In order to help shape clinical practice based on best scientific evidence, the International Conference on 'Multidisciplinary Rectal Cancer Treatment: Looking for an European Consensus' (EURECA-CC2) was organized. This article summarizes the consensus about imaging and radiotherapy of rectal cancer and gives an update until May 2010. Methods. Consensus was achieved using the Delphi method. Eight chapters were identified: epidemiology, diagnostics, pathology, surgery, radiotherapy and chemotherapy, treatment toxicity and quality of life, follow-up, and research questions. Each chapter was subdivided by topic, and a series of statements were developed. Each committee member commented and voted, sentence by sentence three times. Sentences which did not reach agreement after voting round no 2 were openly debated during the Conference in Perugia (Italy) December 2008. The Executive Committee scored percentage consensus based on three categories: 'large consensus', 'moderate consensus', 'minimum consensus'. Results. The total number of the voted sentences was 207. Of the 207, 86% achieved large consensus, 13% achieved moderate consensus, and only three (1%) resulted in minimum consensus. No statement was disagreed by more than 50% of members. All chapters were voted on by at least 75% of the members, and the majority was voted on by >85%. Considerable progress has been made in staging and treatment, including radiation treatment of rectal cancer. Conclusions. This Consensus Conference represents an expertise opinion process that may help shape future programs, investigational protocols, and guidelines for staging and treatment of rectal cancer throughout Europe. In spite of substantial progress, many research challenges remain

  8. Helical CT in acute lower gastrointestinal bleeding

    Ernst, Olivier; Leroy, Christophe; Sergent, Geraldine [Department of Radiology, Hopital Huriez, 1 rue Polonovski, 59037 Lille (France); Bulois, Philippe; Saint-Drenant, Sophie; Paris, Jean-Claude [Department of Gastroenterology, Hopital Huriez, 1 rue Polonovski, 59037 Lille (France)


    The purpose of this study was to assess the usefulness of helical CT in depicting the location of acute lower gastrointestinal bleeding. A three-phase helical CT of the abdomen was performed in 24 patients referred for acute lower gastrointestinal bleeding. The diagnosis of the bleeding site was established by CT when there was at least one of the following criteria: spontaneous hyperdensity of the peribowel fat; contrast enhancement of the bowel wall; vascular extravasation of the contrast medium; thickening of the bowel wall; polyp or tumor; or vascular dilation. Diverticula alone were not enough to locate the bleeding site. The results of CT were compared with the diagnosis obtained by colonoscopy, enteroscopy, or surgery. A definite diagnosis was made in 19 patients. The bleeding site was located in the small bowel in 5 patients and the colon in 14 patients. The CT correctly located 4 small bowel hemorrhages and 11 colonic hemorrhages. Diagnosis of the primary lesion responsible for the bleeding was made in 10 patients. Our results suggest that helical CT could be a good diagnostic tool in acute lower gastrointestinal bleeding to help the physician to diagnose the bleeding site. (orig.)

    To report our experiences of transarterial embolization for acute intercostal artery bleeding. A retrospectively analysis of the causes, clinical manifestations, angiographic findings and transarterial embolization technique in 8 patients with acute intercostal artery bleeding, with a review of the anatomical basis. The causes of intercostal artery bleeding were iatrogenic and traumatic in 88 and 12% of cases, respectively. Active bleeding from the collateral intercostal or posterior intercostal arteries was angiographically demonstrated in 75 and 25% of cases, respectively. Transarterial embolization successfully achieved hemostasis in all cases. However, two patient with hypovolemic shock expired due to a massive hemothorax, despite successful transarterial embolization. Intercostal access should be performed through the middle of the intercostal space to avoid injury to the collateral intercostal artery. Transarterial embolization is an effective method for the control of intercostal artery bleeding.

    Purpose: To assess the impacts of patient age and comorbid illness on rectal toxicity following external beam radiation therapy (EBRT) for prostate cancer and to assess the Qualitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC) normal tissue complication probability (NTCP) model in this context. Methods and Materials: Rectal toxicity was analyzed in 718 men previously treated for prostate cancer with EBRT (≥75 Gy). Comorbid illness was scored using the Charlson Comorbidity Index (CCMI), and the NTCP was evaluated with the QUANTEC model. The influence of clinical and treatment-related parameters on rectal toxicity was assessed by Kaplan-Meier and Cox proportional hazards models. Results: The cumulative incidence of rectal toxicity grade ≥2 was 9.5% and 11.6% at 3 and 5 years and 3.3% and 3.9% at 3 and 5 years for grade ≥3 toxicity, respectively. Each year of age predicted an increasing relative risk of grade ≥2 (P<.03; hazard ratio [HR], 1.04 [95% confidence interval (CI), 1.01-1.06]) and ≥3 rectal toxicity (P<.0001; HR, 1.14 [95% CI,1.07-1.22]). Increasing CCMI predicted rectal toxicity where a history of either myocardial infarction (MI) (P<.0001; HR, 5.1 [95% CI, 1.9-13.7]) or congestive heart failure (CHF) (P<.0006; HR, 5.4 [95% CI, 0.6-47.5]) predicted grade ≥3 rectal toxicity, with lesser correlation with grade ≥2 toxicity (P<.02 for MI, and P<.09 for CHF). An age comorbidity model to predict rectal toxicity was developed and confirmed in a validation cohort. The use of anticoagulants increased toxicity independent of age and comorbidity. NTCP was prognostic for grade ≥3 (P=.015) but not grade ≥2 (P=.49) toxicity. On multivariate analysis, age, MI, CHF, and an NTCP >20% all correlated with late rectal toxicity. Conclusions: Patient age and a history of MI or CHF significantly impact rectal toxicity following EBRT for the treatment of prostate cancer, even after controlling for NTCP.

  13. Multidisciplinary management strategies for acute non-variceal upper gastrointestinal bleeding.

    Lu, Y; Loffroy, R; Lau, J Y W; Barkun, A


    The modern management of acute non-variceal upper gastrointestinal bleeding is centred on endoscopy, with recourse to interventional radiology and surgery in refractory cases. The appropriate use of intervention to optimize outcomes is reviewed. A literature search was undertaken of PubMed and the Cochrane Central Register of Controlled Trials between January 1990 and April 2013 using validated search terms (with restrictions) relevant to upper gastrointestinal bleeding. Appropriate and adequate resuscitation, and risk stratification using validated scores should be initiated at diagnosis. Coagulopathy should be corrected along with blood transfusions, aiming for an international normalized ratio of less than 2·5 to proceed with possible endoscopic haemostasis and a haemoglobin level of 70 g/l (excluding patients with severe bleeding or ischaemia). Prokinetics and proton pump inhibitors (PPIs) can be administered while awaiting endoscopy, although they do not affect rebleeding, surgery or mortality rates. Endoscopic haemostasis using thermal or mechanical therapies alone or in combination with injection should be used in all patients with high-risk stigmata (Forrest I-IIb) within 24 h of presentation (possibly within 12 h if there is severe bleeding), followed by a 72-h intravenous infusion of PPI that has been shown to decrease further rebleeding, surgery and mortality. A second attempt at endoscopic haemostasis is generally made in patients with rebleeding. Uncontrolled bleeding should be treated with targeted or empirical transcatheter arterial embolization. Surgical intervention is required in the event of failure of endoscopic and radiological measures. Secondary PPI prophylaxis when indicated and Helicobacter pylori eradication are necessary to decrease recurrent bleeding, keeping in mind the increased false-negative testing rates in the setting of acute bleeding. An evidence-based approach with multidisciplinary collaboration is required to optimize

    Full Text Available Introduction Patients with mild to moderate bleeding symptoms referred for coagulation investigation sometimes never receive a definitive diagnosis. Bleed assessment tools have been developed and validated to assess the severity of symptoms. Global coagulation assays, e.g., the thrombin generation test (thrombogram have a potential to identify hemostatic defects that are not detected in specific assays. Material and Methods One hundred and eighty-five patients referred to our centre because of bleeding symptoms were evaluated using  the bleeding assessment tool (BAT described by Tosetto and colleagues in 2006.  Blood samples were investigated for thrombin generation (TG capacity (Technoclone , in platelet poor (PPP  plasma , and specific clotting factors, i.e, von Willebrand factor, factor VIII and IX, as well as INR, APTT, platelet count, and platelet adhesion. Results Of the 185 patients, five women were diagnosed with mild von Willebrand disease and one male with mild hemophilia A. The remaining 179 subjects (76% females and 24% males with average ages of 33 and 28 years, respectively were evaluated further. In the total cohort and among women, peak TG, and lag time   correlated with bleeding score (p=0.01 and p=0.04, respectively with correlation coefficients.  No such correlations were found among males.   Discussion and conclusion   Although our study showed some correlation between TG and bleeding score, results are generally consistent with a previous report which failed to demonstrate the value of TG measurement in a similar setting. In conclusion, the complexity of the mechanisms underlying clinical bleeding complicates the ability to use TG tests as reliable predictors of bleeding. Mild congenital bleeding disorders, especially VWD, should be specifically screened for in patients with mild/moderate symtoms.

  15. Long-term bleeding risk prediction in 'real world' patients with atrial fibrillation: Comparison of the HAS-BLED and ABC-Bleeding risk scores. The Murcia Atrial Fibrillation Project.

    Esteve-Pastor, María Asunción; Rivera-Caravaca, José Miguel; Roldan, Vanessa; Vicente, Vicente; Valdés, Mariano; Marín, Francisco; Lip, Gregory Y H


    Risk scores in patients with atrial fibrillation (AF) based on clinical factors alone generally have only modest predictive value for predicting high risk patients that sustain events. Biomarkers might be an attractive prognostic tool to improve bleeding risk prediction. The new ABC-Bleeding score performed better than HAS-BLED score in a clinical trial cohort but has not been externally validated. The aim of this study was to analyze the predictive performance of the ABC-Bleeding score compared to HAS-BLED score in an independent "real-world" anticoagulated AF patients with long-term follow-up. We enrolled 1,120 patients stable on vitamin K antagonist treatment. The HAS-BLED and ABC-Bleeding scores were quantified. Predictive values were compared by c-indexes, IDI, NRI, as well as decision curve analysis (DCA). Median HAS-BLED score was 2 (IQR 2-3) and median ABC-Bleeding was 16.5 (IQR 14.3-18.6). After 6.5 years of follow-up, 207 (2.84 %/year) patients had major bleeding events, of which 65 (0.89 %/year) had intracranial haemorrhage (ICH) and 85 (1.17 %/year) had gastrointestinal bleeding events (GIB). The c-index of HAS-BLED was significantly higher than ABC-Bleeding for major bleeding (0.583 vs 0.518; p=0.025), GIB (0.596 vs 0.519; p=0.017) and for the composite of ICH-GIB (0.593 vs 0.527; p=0.030). NRI showed a significant negative reclassification for major bleeding and for the composite of ICH-GIB with the ABC-Bleeding score compared to HAS-BLED. Using DCAs, the use of HAS-BLED score gave an approximate net benefit of 4 % over the ABC-Bleeding score. In conclusion, in the first "real-world" validation of the ABC-Bleeding score, HAS-BLED performed significantly better than the ABC-Bleeding score in predicting major bleeding, GIB and the composite of GIB and ICH.

  16. The pharmacokinetics of a single oral or rectal dose of concurrently administered isoniazid, rifampin, pyrazinamide, and ethambutol in Asian elephants (Elephas maximus).

    P Brock, A; Isaza, R; Egelund, E F; Hunter, R P; Peloquin, C A


    Tuberculosis, caused by Mycobacterium tuberculosis, is a disease of concern in captive Asian elephants (Elephas maximus). Treatment for tuberculosis in elephants utilizes multidrug protocols combining isoniazid, rifampin, pyrazinamide, and/or ethambutol. In this study, a single, coformulated dose of isoniazid 5 mg/kg, rifampin 10 mg/kg, pyrazinamide 30 mg/kg, and ethambutol 30 mg/kg was administered orally to six Asian elephants, and rectally to five elephants using a cross-over design. Blood samples were collected serially over 24 h. Pyrazinamide and ethambutol concentrations were determined using validated gas chromatography assays. Isoniazid and rifampin concentrations were determined using validated high-performance liquid chromatography assays. Rectal isoniazid produced an earlier Tmax compared with oral administration. Oral isoniazid resulted in a comparatively lower Cmax , but higher AUC values compared with rectal isoniazid. Oral rifampin and oral ethambutol were well absorbed while rectal rifampin was not. Oral pyrazinamide produced comparatively higher Cmax and AUC values compared with rectal pyrazinamide. Results of this study indicate that currently recommended therapeutic monitoring sample collection times for rectal isoniazid and oral rifampin do not provide an accurate assessment of exposure for these drugs. This study demonstrates notable individual variability, indicating that dosing of these medications requires individual monitoring and provides additional information to guide the clinician when treating elephants.

  17. Advanced rectal cancer in a long-term Hartmann's pouch: a forgotten organ revisited.

    Al Maksoud, Ahmed Mahmoud Abd El Aziz; Ahmed, Iftikhar


    Hartmann's procedure is widely performed as a first-stage operation in cases of left colon emergencies when a one stage management is judged to be unsafe. Forty per cent of patients with Hartmann's procedure never get their stoma reversed, ending with a permanent stoma. The distal excluded Hartmann's pouch is usually forgotten compared to the proximal functioning colon. A 70-year-old man with Hartmann's procedure carried out previously for complicated diverticular disease presented with bleeding per rectum. Invasive adenocarcinoma was confirmed on histology. Subsequent staging revealed a locally advanced rectal cancer. The tumour progressed despite a course of neoadjuvant chemoradiation. The general condition of the patient deteriorated with development of renal failure. The patient died a few weeks later. By reporting this case, we are revisiting the long forgotten Hartmann's pouch to highlight the potential pathologies in the distal stump and to emphasise that a distal stump should not be forgotten even in asymptomatic patients. 2016 BMJ Publishing Group Ltd.

    Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcomings of this method are the inability to fix the knife to the target lesion, and compression of the lesion. These can lead to major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using electrosurgical current. Colonoscopy on a 55-year-old woman revealed a 10-mm rectal submucosal nodule. The histological diagnosis of the specimen obtained by biopsy was carcinoid tumor. Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement. It was safely and accurately resected without unexpected incision by ESD using a GSF. No delayed hemorrhage or perforation occurred. Histological examination confirmed the carcinoid tumor was completely excised with negative resection margin.

  19. Late results of mucosal proctectomy and colo-anal sleeve anastomosis for chronic irradiation rectal injury

    Browning, G.G.P.; Varma, J.S.; Smith, A.N.; Small, W.P.; Duncan, W.


    Ten patients with severe chronic irradiation injury to the rectum were treated by mucosal proctectomy and colo-anal sleeve anastomosis. The indications were: recurrent rectal bleeding (five), stricture (three), fistula (one) and intractable pain (one). Overall follow-up has ranged from 8 to 77 months (mean 40 months). In the present survivors (n=7) the follow-up ranges from 18 to 77 months (mean 52 months). Six patients have been followed up for more than 3 years and four for more than 5 years. There was no operative mortality. Three anastomotic strictures occurred but the protecting stoma could be closed in all but one patient. Continence was acceptable although urgency and frequency of defaecation were troublesome symptoms. The operation is recommended for life-threatening, haemorrhagic chronic irradiation injury to the rectum.

    Сергій Олександрович Сокольник


    Full Text Available Aim. To elaborate the step-by-step differential algorithm of the motion of children with ulcerative gastroduodenal bleedings. Methods. There were examined 45 patients with gastroduodenal bleeding of ulcerative genesis using clinical, sociometric, genealogic, immune-enzyme, biochemical, endoscopic, functional methods. In the complex treatment for stop bleeding 13 patients underwent argon-plasma coagulation and the other – irrigation with aminocapronic acid. An efficiency of treatment was evaluated using epidemiologic and statistical methods.Results. At presence of an appropriate clinical symptomatology, burdened genealogic anamnesis, laboratory changes it is necessary to carry out an emergency endoscopic examination. In the case of continuing bleeding or instable homeostasis it is recommended to carry out an endoscopic hemostasis using argon-plasma coagulation, in conditions of the high risk of relapse of bleeding – the repeated course of argon-plasma coagulation. After stabilization - an examination for helicobacter infection, conservative therapy and dynamic observation with detection of risk of relapse of bleeding and elaboration of individualized medioprophylactic program.Conclusions. The use of step-by-step differentiated diagnostic and treatment algorithm of the motion in patients with ulcerative disease complicated with gastroduodenal bleeding allows detect the main spectrum of diagnostic researches faster and choose the tactics of treatment and therefore improve an efficiency of medical help for patient and shorten the term of inpatient treatment. 

  1. Transanal Evisceration Caused by Rectal Laceration

    Torres Sánchez, María Teresa; Richart Aznar, Jose Manuel; Martí Martínez, Eva María; Martínez-Abad, Manuel


    Transrectal evisceration caused by colorectal injury is an unusual entity. This pathology is more frequent in elderly patients and it is usually produced spontaneously. Rectal prolapse is the principal predisposing factor. An 81-year-old woman was taken to the hospital presenting exit of intestinal loops through the anus. After first reanimation measures, an urgent surgery was indicated. We observed the absence of almost every small intestine loop in the abdominal cavity; these had been moved to the pelvis. After doing the reduction, a 3 to 4 cm linear craniocaudal perforation in upper rectum was objectified, and Hartmann's procedure was performed. We investigated and knew that she frequently manipulate herself to extract her faeces. The fast preoperative management avoided a fatal conclusion or an extensive intestinal resection. Reasons that make us consider rectal self-injury as the etiologic factor are explained. PMID:24639971

  2. UFT (tegafur-uracil) in rectal cancer

    Casado, E; Pfeiffer, P; Feliu, J


    BACKGROUND: Major achievements in the treatment of localised rectal cancer include the development of total mesorectal excision and the perioperative administration of radiotherapy in combination with continuous infusion (CI) 5-fluorouracil (5-FU). This multimodal approach has resulted in extended...... survival and lower local relapse rates, with the potential for sphincter-preserving procedures. However, CI 5-FU is inconvenient for patients and is costly. Oral fluoropyrimidines like UFT (tegafur-uracil) offer a number of advantages over 5-FU. METHODS: We undertook a review of published articles...... and abstracts relating to clinical studies of UFT in the treatment of locally advanced rectal cancer (LARC). Pre- and postoperative studies carried out in patients with newly diagnosed or recurrent disease were included. RESULTS: The combination of UFT and radiotherapy was effective and well tolerated...

  3. Synchronous rectal adenocarcinoma and anal canal adenocarcinoma

    GU Jin; LI Jiyou; YAO Yunfeng; LU Aiping; WANG Hongyi


    It is difficult to distinguish a tectal carcinoma with anal metastases from coexistent synchronous anorectal carcinomas.The therapeutic strategy for rectal and anal carcinoma is so different that it should be clearly identified.Here,we report on the case of a 63-year-old man who presented with an upper-third rectal adenocarcinoma.Five months after resection,he developed an adenocarcinoma in the anal canal.The histological slides of both tumors were reviewed and immunohistochemical studies for cytokeratins(CKs)7 and 20 were performed.The index tumor demonstrated CK 7-/CK 20+and the second showed CK7+/CK20+.For this reason,we believe the present case had synchronous adenocarcinomas arising from anal canal and the rectum separately.It is very important to difierentiate the anorectal lesions pathologically because of the impact on the therapeutic options available,especially for the lesion arising in the anal canal.

  6. Upper gastrointestinal bleeding - state of the art.

    Szura, Mirosław; Pasternak, Artur


    Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

  8. Compressor bleed cooling fluid feed system

    Donahoo, Eric E; Ross, Christopher W


    A compressor bleed cooling fluid feed system for a turbine engine for directing cooling fluids from a compressor to a turbine airfoil cooling system to supply cooling fluids to one or more airfoils of a rotor assembly is disclosed. The compressor bleed cooling fluid feed system may enable cooling fluids to be exhausted from a compressor exhaust plenum through a downstream compressor bleed collection chamber and into the turbine airfoil cooling system. As such, the suction created in the compressor exhaust plenum mitigates boundary layer growth along the inner surface while providing flow of cooling fluids to the turbine airfoils.

  9. Lower Gastrointestinal Bleeding in Chronic Hemodialysis Patients

    Fahad Saeed


    Full Text Available Gastrointestinal (GI bleeding is more common in patients with chronic kidney disease and is associated with higher mortality than in the general population. Blood losses in this patient population can be quite severe at times and it is important to differentiate anemia of chronic diseases from anemia due to GI bleeding. We review the literature on common causes of lower gastrointestinal bleeding (LGI in chronic kidney disease (CKD and end-stage renal disease (ESRD patients. We suggest an approach to diagnosis and management of this problem.

  10. Fine needle aspiration cytology of rectal masses.

    Kochhar, R; Rajwanshi, A; Wig, J D; Gupta, N M; Kesiezie, V; Bhasin, D K; Malik, A K; Gupta, S K; Mehta, S K


    This paper describes the results of transproctoscopic fine needle aspiration cytology in the diagnosis of rectal lesions. Fifty one consecutive patients referred with a presumptive diagnosis of rectal mass were subjected to proctoscopic examination when fine needle aspiration cytology, brush cytology and biopsy samples were taken. Of the 30 patients of malignancy of rectum in whom all the three sampling techniques were applied, the biopsy was positive in 27 (90%), brush cytology in 25 (83.3%) and fine needle aspiration cytology in 29 (96.6%). A combination of fine needle aspiration cytology with brush cytology gave a positive yield in 96.6% while that fine needle aspiration cytology with brush cytology gave a yield of 100%. Fine needle aspiration cytology was most helpful in infiltrative tumours. All 10 patients with secondaries in the pouch of Douglas or rectovesical pouch, and the single patient with submucosal rectal carcinoma were correctly diagnosed at fine needle aspiration cytology. There were no false positive results with fine needle aspiration cytology and no complications were encountered with the procedure. Images Figure 1 Figure 2 Figure 3 PMID:2323600

  11. Increasing trend in retained rectal foreign bodies

    Ayantunde, Abraham A; Unluer, Zynep


    AIM To highlight the rising trend in hospital presentation of foreign bodies retained in the rectum over a 5-year period. METHODS Retrospective review of the cases of retained rectal foreign bodies between 2008 and 2012 was performed. Patients’ clinical data and yearly case presentation with data relating to hospital episodes were collected. Data analysis was by SPSS Inc. Chicago, IL, United States. RESULTS Twenty-five patients presented over a 5-year period with a mean age of 39 (17-62) years and M: F ratio of 2:1. A progressive rise in cases was noted from 2008 to 2012 with 3, 4, 4, 6, 8 recorded patients per year respectively. The majority of the impacted rectal objects were used for self-/partner-eroticism. The commonest retained foreign bodies were sex vibrators and dildos. Ninty-six percent of the patients required extraction while one passed spontaneously. Two and three patients had retrieval in the Emergency Department and on the ward respectively while 19 patients needed examination under anaesthesia for extraction. The mean hospital stay was 19 (2-38) h. Associated psychosocial issues included depression, deliberate self-harm, illicit drug abuse, anxiety and alcoholism. There were no psychosocial problems identified in 15 patients. CONCLUSION There is a progressive rise in hospital presentation of impacted rectal foreign bodies with increasing use of different objects for sexual arousal. PMID:27830039

  12. Preparation and evaluation of mesalamine collagen in situ rectal gel: a novel therapeutic approach for treating ulcerative colitis.

    Ramadass, Satiesh Kumar; Perumal, Sathiamurthi; Jabaris, Sugin Lal; Madhan, Balaraman


    Ulcerative colitis (UC) is a chronic inflammatory disease that primarily affects the colonic mucosa. Mesalamine had been established as a first line drug for treating mild to moderate UC. A continued availability of the drug for treatment of damaged tissues remains a great challenge today. In the present study, a novel mesalamine collagen in situ gel has been prepared using type I collagen, which is pH/temperature sensitive. This hydrogel undergoes sol-gel transition under physiological pH and temperature which was confirmed by rheological studies. The in vitro release profile demonstrated sustained release of mesalamine over a period of 12h. The in vivo efficacy of the in situ gel was performed using dextran sodium sulphate induced ulcerative colitis model in BALB/c mice. The clinical parameters such as, body weight changes, rectal bleeding and stool consistency were evaluated. In addition, the histopathological investigation was conducted to assess severity of mucosal damage and inflammation infiltrate. There was a significant reduction in rectal bleeding and mucosal damage score for collagen-mesalamine in situ gel group compared to the reference group. Apart from releasing mesalamine in controlled manner, the strategy of administering mesalamine through collagen in situ gel facilitates regeneration of damaged mucosa resulting in a synergistic effect for the treatment of ulcerative colitis.

  13. Urogenital function in robotic vs laparoscopic rectal cancer surgery: a comparative study.

    Panteleimonitis, Sofoklis; Ahmed, Jamil; Ramachandra, Meghana; Farooq, Muhammad; Harper, Mick; Parvaiz, Amjad


    Urological and sexual dysfunction are recognised risks of rectal cancer surgery; however, there is limited evidence regarding urogenital function comparing robotic to laparoscopic techniques. The aim of this study was to assess the urogenital functional outcomes of patients undergoing laparoscopic and robotic rectal cancer surgery. Urological and sexual functions were assessed using gender-specific validated standardised questionnaires. Questionnaires were sent a minimum of 6 months after surgery, and patients were asked to report their urogenital function pre- and post-operatively, allowing changes in urogenital function to be identified. Questionnaires were sent to 158 patients (89 laparoscopy, 69 robotic) of whom 126 (80 %) responded. Seventy-eight (49 male, 29 female) of the responders underwent laparoscopic and 48 (35 male, 13 female) robotic surgery. Male patients in the robotic group deteriorated less across all components of sexual function and in five components of urological function. Composite male urological and sexual function score changes from baseline were better in the robotic cohort (p function. However, composite female urological function score change from baseline was better in the robotic group (p = 0.003). Robotic rectal cancer surgery might offer better post-operative urological and sexual outcomes compared to laparoscopic surgery in male patients and better urological outcomes in females. Larger scale, prospective randomised control studies including urodynamic assessment of urogenital function are required to validate these results.

  14. Neoadjuvant Treatment Strategies for Locally Advanced Rectal Cancer.

    Gollins, S; Sebag-Montefiore, D


    Improved surgical technique plus selective preoperative radiotherapy have decreased rectal cancer pelvic local recurrence from, historically, 25% down to about 5-10%. However, this improvement has not reduced distant metastatic relapse, which is the main cause of death and a key issue in rectal cancer management. The current standard is local pelvic treatment (surgery ± preoperative radiotherapy) followed by adjuvant chemotherapy, depending on resection histology. For circumferential resection margin (CRM)-threatened cancer on baseline magnetic resonance imaging, downstaging long-course preoperative chemoradiation (LCPCRT) is generally used. However, for non-CRM-threatened disease, varying approaches are currently adopted in the UK, including straight to surgery, short-course preoperative radiotherapy and LCPCRT. Clinical trials are investigating intensification of concurrent chemoradiation. There is also increasing interest in investigating preoperative neoadjuvant chemotherapy (NAC) as a way of exposing micro-metastatic disease to full-dose systemic chemotherapy as early as possible and potentially reducing metastatic relapse. Phase II trials suggest that this strategy is feasible, with promising histological response and low rates of tumour progression during NAC. Phase III trials are needed to determine the benefit of NAC when added to standard therapy and also to determine if it can be used instead of neoadjuvant radiotherapy-based schedules. Although several measures of neoadjuvant treatment response assessment based on imaging or pathology are promising predictive biomarkers for long-term survival, none has been validated in prospective phase III studies. The phase III setting will enable this, also providing translational opportunities to examine molecular predictors of response and survival. Copyright © 2015 The Royal College of Radiologists.

    Matias Riihimäki; Akseli Hemminki; Jan Sundquist; Kari Hemminki


    Investigating epidemiology of metastatic colon and rectal cancer is challenging, because cancer registries seldom record metastatic sites. We used a population based approach to assess metastatic spread in colon and rectal cancers. 49,096 patients with colorectal cancer were identified from the nationwide Swedish Cancer Registry. Metastatic sites were identified from the National Patient Register and Cause of Death Register. Rectal cancer more frequently metastasized into thoracic organs (OR ...

  16. Screening for a raised rectal temperature in Africa.

    Jones, R.J.; O'Dempsey, T J; Greenwood, B. M.


    The main purpose of this study was to compare rectal and axillary temperature measurements in African children. Altogether 573 sick children were seen in an outpatient setting in rural West Africa. Rectal and axillary temperatures were measured and the parent or guardian was asked if they thought that the child had a raised body temperature. Normal ranges were defined from an age matched population of 203 healthy children. A raised axillary temperature predicted a raised rectal temperature wi...

  17. Complete perineal tear with rectal prolapse: an unusual case report.

    Mukhopadhyay, Sima; Bhattacharyya, Subir Kumar; Ganguly, Rajendra Prasad; Patra, Kajal Kumar


    The association of complete perineal tear and rectal prolapse is less reported in literature, although isolated complete perineal tear and the combinations of vaginal and rectal prolapse are not so unusual, where multiparity and unsupervised home deliveries are quiet common. An interesting case of long standing complete perineal tear with complete rectal prolapse is reported in a 60 years old lady along with review of literature, discussing the management and follow-up of the condition.

  18. Dosimetric uncertainties related to the elasticity of bladder and rectal walls: Adenocarcinoma of the prostate

    Voyant, Cyril; Delphine, Leschi; Briancon, Jerome; Marcovici, Celine Lantieri; 10.1016/j.canrad.2010.12.006


    Purpose. - Radiotherapy is an important treatment for prostate cancer.During treatment sessions, bladder and rectal repletion is difficult to quantify and cannot be measured with a single and initial CT scan acquisition. Some methods, such as image-guided radiation therapy and dose-guided radiation therapy, aimto compensate thismissing information through periodic CT acquisitions. The aimis to adapt patient's position, beam configuration or prescribed dose for a dosimetric compliance. Methods. -We evaluated organmotion (and repletion) for 54 patients after having computed the original ballistic on a new CT scan acquisition. A new delineation was done on the prostate, bladder and rectum to determine the newdisplacements and define organ dosesmistakes (equivalent uniformdose, average dose and dose-volume histograms). Results. - The new CT acquisitions confirmed that bladder and rectal volumes were not constant during sessions. Some cases showed that previously validated treatment plan became unsuitable. A propo...

  19. Bleeding and starving: fasting and delayed refeeding after upper gastrointestinal bleeding.

    Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall score; endoscopic data, including severity of lesions and therapy; feeding related records of seven days: liquid diet prescription, first liquid intake, soft/solid diet prescription, first soft/solid intake. From 133 patients (84 men) Rockall classification was possible in 126: 76 score ≥5, 50 score bleeding, eight rebled, two underwent surgery, 13 died. Ulcer was the major bleeding cause, 63 patients underwent endoscopic therapy. There was 142/532 possible refeeding records, no record 37% patients. Only 16% were fed during the first day and half were only fed on third day or later. Rockall upper gastrointestinal bleeding patients must be refed earlier, according to guidelines.

  20. Bleeding time in uremia: a useful test to assess clinical bleeding.

    Steiner, R W; Coggins, C; Carvalho, A C


    Modified Ivy bleeding time (template) and platelet aggregation to ADP, epinephrine, and collagen were studied in 26 uremic patients who had not recently ingested anti-platelet drugs. Regardless of the aggregating agent used, the abnormalities in platelet aggregation were often mild, even with advanced uremia, and frequently less severe than the effects of common anti-platelet drugs. The inhibition of collagen-induced aggregation was significantly correlated with both increased bleeding time and blood urea nitrogen. Platelet aggregation was not discriminative between clinically bleeding and non-bleeding groups of patients, but the bleeding time was helpful in this regard. In certain cases, the aggregometric patterns differed between drug-induced and uremic thrombocytopathies. Platelet aggregometry appears to be of little help clinically in assessing the severity of the uremic bleeding diathesis.

  1. Genetic analysis of bleeding disorders.

    Edison, E; Konkle, B A; Goodeve, A C


    Molecular genetic analysis of inherited bleeding disorders has been practised for over 30 years. Technological changes have enabled advances, from analyses using extragenic linked markers to next-generation DNA sequencing and microarray analysis. Two approaches for genetic analysis are described, each suiting their environment. The Christian Medical Centre in Vellore, India, uses conformation-sensitive gel electrophoresis mutation screening of multiplexed PCR products to identify candidate mutations, followed by Sanger sequencing confirmation of variants identified. Specific analyses for F8 intron 1 and 22 inversions are also undertaken. The MyLifeOurFuture US project between the American Thrombosis and Hemostasis Network, the National Hemophilia Foundation, Bloodworks Northwest and Biogen uses molecular inversion probes (MIP) to capture target exons, splice sites plus 5' and 3' sequences and to detect F8 intron 1 and 22 inversions. This allows screening for all F8 and F9 variants in one sequencing run of multiple samples (196 or 392). Sequence variants identified are subsequently confirmed by a diagnostic laboratory. After having identified variants in genes of interest through these processes, a systematic procedure determining their likely pathogenicity should be applied. Several scientific societies have prepared guidelines. Systematic analysis of the available evidence facilitates reproducible scoring of likely pathogenicity. Documentation of frequency in population databases of variant prevalence and in locus-specific mutation databases can provide initial information on likely pathogenicity. Whereas null mutations are often pathogenic, missense and splice site variants often require in silico analyses to predict likely pathogenicity and using an accepted suite of tools can help standardize their documentation.

  2. Acute Lower Gastrointestinal Bleeding: Part I

    Robert Enns


    Full Text Available Acute lower gastrointestinal (LGI bleeding is typically caused by vascular malformations, diverticuli and neoplasia. Although endoscopic evaluation of the colon is relatively standard in stable patients with LGI bleeding, those with significant ongoing hemorrhage are often more difficult to evaluate endoscopically. Other investigative techniques such as nuclear scintigraphy, angiography and surgical exploration have been commonly used in unstable patients with LGI bleeding when the exact site is unknown. These investigative techniques have had variable measures of success. This two-part review evaluates the literature in an attempt to review the optimal investigative approach in patients with LGI hemorrhage, in particular patients who have had significant and ongoing bleeding. Part 1 of this article concentrates on the etiology of LGI hemorrhage, followed in a subsequent article by diagnostic and management strategies. Following the review, a consensus update will be included with guidelines for clinical use.

  4. Gastrointestinal bleeding in the pediatric patient.

    Hillemeier, C.; Gryboski, J. D.


    Gastrointestinal hemorrhage in infants and children is a catastrophic event but is not associated with significant mortality except in those with a severe primary illness. Upper gastrointestinal bleeding in infants and young children is most often associated with stress ulcers or erosions, but in older children it may also be caused by duodenal ulcer, esophagitis, and esophageal varices. Lower gastrointestinal bleeding may be caused by a variety of lesions among which are infectious colitides...

    Park, Jae Hyung; Sung, Kyu Bo; Koo, Kyung Hoi; Bae, Tae Young; Chung, Eun Chul; Han, Man Chung [Seoul National University College of Medicine, Seoul (Korea, Republic of)


    Diagnostic angiographic evaluations were done in 33 patients with gastrointestinal bleeding for recent 5 years at Department of Radiology, Seoul National University Hospital. On 11 patients of them, therapeutic interventional procedures were made and the results were analysed. 1. In a total of 33 cases, there were 18 cases of upper GI bleeding and 15 cases of lower GI bleeding. The most frequent causes were peptic ulcer in the former and intestinal typhoid fever in the latter. 2. Bleeding sites were localized angiographically in 28 cases, so the detection rate was 85%. Four of the five angiographically negative cases were lower GI bleeding cases. 3. The most frequent bleeding site was left gastric artery (7/33). The next was ileocecal branch of superior mesenteric artery (6/33). 4. Among the 11 interventional procedures, Gelfoam embolization was done in 7 cases and Vasopressin infusion was tried in 4 cases. They were successful in 4 and 3 cases, suggesting 57% and 47% success rates respectively.

  7. Bleeding from gastrointestinal angioectasias is not related to bleeding disorders - a case control study

    Lärfars Gerd


    Full Text Available Abstract Background Angioectasias in the gastrointestinal tract can be found in up to 3% of the population. They are typically asymptomatic but may sometimes result in severe bleeding. The reasons for why some patients bleed from their angioectasias are not fully understood but it has been reported that it may be explained by an acquired von Willebrand syndrome (AVWS. This condition has similar laboratory findings to congenital von Willebrand disease with selective loss of large von Willebrand multimers. The aim of this study was to find out if AVWS or any other bleeding disorder was more common in patients with bleeding from angioectasias than in a control group. Methods We compared bleeding tests and coagulation parameters, including von Willebrand multimers, from a group of 23 patients with anemia caused by bleeding from angioectasias, with the results from a control group lacking angioectasias. Results No significant differences between the two groups were found in coagulation parameters, bleeding time or von Willebrand multimer levels. Conclusion These results do not support a need for routine bleeding tests in cases of bleeding from angioectasias and do not show an overall increased risk of AVWS among these patients.

  8. Biopsy of the prostate guided by transrectal ultrasound: relation between warfarin use and incidence of bleeding complications

    Ihezue, C.U. [Department of Radiology, Southampton General Hospital (United Kingdom); Smart, J. [Department of Radiology, Southampton General Hospital (United Kingdom); Dewbury, K.C. [Department of Radiology, Southampton General Hospital (United Kingdom)]. E-mail:; Mehta, R. [Department of Radiology, Southampton General Hospital (United Kingdom); Burgess, L. [Department of Radiology, Southampton General Hospital (United Kingdom)


    AIM: To determine the relation between warfarin use and the frequency of bleeding complications after biopsy of the prostate guided by transrectal ultrasound (TRUS). METHODS: Overall, 1022 consecutive patients with suspected prostatic disease were followed after biopsy. Warfarin and aspirin use was determined on the day of the procedure. A TRUS-guided biopsy was performed and patients were offered a questionnaire to complete 10 days after the procedure, to determine any immediate or delayed bleeding complications. Follow-up telephone calls were made to those who had not replied within the stipulated period. RESULTS: Of the 1000 patients who replied, 49 were receiving warfarin, 220 were receiving aspirin and 731 were not receiving any anticoagulant drugs. Of the 49 subjects reporting current use of warfarin, 18 (36.7%) experienced haematuria, compared with 440 (60.2%) of the patients receiving no anti-coagulant drugs who reported haematuria. This was statistically significant (p=0.001). Of the group receiving warfarin, 4 (8.2%) experienced haematospermia whereas 153 (21%) of the group receiving no anticoagulant medication reported haematospermia. This difference also was statistically significant (p=0.030). Rectal bleeding was experienced by 7 (14.3%) of the group receiving warfarin compared with 95 (13%) in the group without anticoagulant medication, but this was not statistically significant (p=0.80). We also demonstrated that there was no statistically significant association between the severity of the bleeding complications and medication with warfarin. CONCLUSION: None of the group receiving warfarin experienced clinically important bleeding complications. Our results suggest that the frequency and severity of bleeding complications were no worse in the warfarin group than in the control group and that discontinuing anticoagulation medication before prostate biopsy may be unnecessary.

  9. Comparison of ACUITY and CRUSADE Scores in Predicting Major Bleeding during Acute Coronary Syndrome

    Luis C. L. Correia


    Full Text Available Background:The ACUITY and CRUSADE scores are validated models for prediction of major bleeding events in acute coronary syndrome (ACS. However, the comparative performances of these scores are not known.Objective:To compare the accuracy of ACUITY and CRUSADE in predicting major bleeding events during ACS.Methods:This study included 519 patients consecutively admitted for unstable angina, non-ST-elevation or ST-elevation myocardial infarction. The scores were calculated based on admission data. We considered major bleeding events during hospitalization and not related to cardiac surgery, according to the Bleeding Academic Research Consortium (BARC criteria (type 3 or 5: hemodynamic instability, need for transfusion, drop in hemoglobin ≥ 3 g, and intracranial, intraocular or fatal bleeding.Results:Major bleeding was observed in 31 patients (23 caused by femoral puncture, 5 digestive, 3 in other sites, an incidence of 6%. While both scores were associated with bleeding, ACUITY demonstrated better C-statistics (0.73, 95% CI = 0.63 - 0.82 as compared with CRUSADE (0.62, 95% CI = 0.53 - 0.71; p = 0.04. The best performance of ACUITY was also reflected by a net reclassification improvement of + 0.19 (p = 0.02 over CRUSADE’s definition of low or high risk. Exploratory analysis suggested that the presence of the variables ‘age’ and ‘type of ACS’ in ACUITY was the main reason for its superiority.Conclusion:The ACUITY Score is a better predictor of major bleeding when compared with the CRUSADE Score in patients hospitalized for ACS.

  10. [Massive rectal blood loss after colonoscopy

    Kampschreur, M.T.; Kats-Ugurlu, G.; Suylen, R.J. van; Schryver, A.M. de


    A 70-year-old man presented with acute lower gastrointestinal bleeding. A colonoscopy performed one and a half months prior had revealed diverticulosis in the sigmoid colon; a small polyp located 10 cm from the anal margin had been removed at that time. The presenting patient was haemodynamically un

  12. Identification and management of women with inherited bleeding disorders: a survey of obstetricians and gynaecologists in the United Kingdom.

    Chi, C; Shiltagh, N; Kingman, C E C; Economides, D L; Lee, C A; Kadir, R A


    A mail survey of members and fellows of Royal College of Obstetricians and Gynaecologists was carried out to determine current practices of obstetricians and gynaecologists in the United Kingdom in the management of women with inherited bleeding disorders. In total, 3929 questionnaires were sent, 707 returned and analysis was limited to 545 valid questionnaires. In the past 5 years, 91% have managed women with inherited bleeding disorders. The majority (83%) considered inherited bleeding disorders to be under diagnosed in obstetrics and gynaecology. More than 80% considered the prevalence of von Willebrand's disease (VWD) to be management guidelines are essential in minimizing haemorrhagic complications and improving quality of care of these women.

  13. Carcinoma of the prostate treated by pelvic node dissection, iodine-125 seed implant and external irradiation; a study of rectal complications

    Abadir, R.; Ross, G. Jr.; Weinstein, S.H. (Missouri Univ., Columbia (USA). Hospital and Clinics)


    The University of Missouri-Columbia protocol for localised cancer of the prostate calls for pelvic node dissection, 10 000 cGy at the periphery of the prostate from /sup 125/I and 4000 cGy in 20 fractions to the whole pelvis using supervoltage X-ray therapy. Rectal complications were studied in 104 patients; acute and chronic reactions were defined. During external irradiation 54% did not develop diarrhoea, 43% had mild diarrhoea and 3% had severe diarrhoea. In the chronic stage 77% did not have diarrhoea, 12% had delayed, non-distressing rectal bleeding which did not need specific treatment or needed only simple treatment, 7% had prolonged distressing proctitis and 4% had rectal ulceration or recto-urethral fistula necessitating colostomy. Each of the four patients who had colostomy had an additional aetiological factor (arterial disease, pelvic inflammation, additional radiation, pelvic malignancy or second operation). None of the patients entered in the combined brachytherapy and teletherapy programme, and in whom 0.5 cm space was maintained between the closest seed and the rectal mucosa, developed prolonged proctitis.

  14. [Local excision of giant rectal polypoid neoplasms].

    Cimitan, Andrea; Burza, Antonio; Basile, Ursula; Saputo, Serena; Mingazzini, Pietro; Stipa, Francesco


    Local excision is the best therapeutic option for giant adenomas of the rectum. Parks technique for lower rectal lesions and the T.E.M. technique for lesions localised in the middle and upper rectum offer exceptionally good exposure, allowing radical excision in the case of early low-risk T1 adenocarcinomas (well or moderately differentiated [G1/2] without lymphovascular invasion [L0]). From July 1987 to March 2006, 224 patients were treated by local excision for rectal lesions in our department. In 48 patients (21.4%) a large sessile benign lesion was diagnosed preoperatively. In 3 patients with a preoperative diagnosis of severe dysplasia (Tis) final pathology showed adenoma and for this reason they were included in our study group. A total of 51 patients with giant preoperative benign lesions were treated by local excision (Parks technique, T.E.M. or both). Twenty-five (49%) patients had a definitive diagnosis of adenocarcinoma: in situ (pTis) in 22 patients (88%), pT1 in 2 patients (8%) and pT2 in 1 patient (4%). In 26 patients (51%) the diagnosis was adenoma. The overall local recurrence rate was 9.8% (5/51); the recurrence rate was 7.6% (2/26) for adenomas and 12% (3/25) for carcinomas. The median hospital stay was 7 days (range 3-39). There was no operative mortality. Giant sessile polypoid lesions localized in the middle and upper rectum are best treated with T.E.M., while Parks technique is a good option in lower rectal tumours. These techniques, if correctly indicated and well performed, offer great advantages in terms of safety and radicality. In our experience the operative mortality was nil and the morbidity and recurrence rates were low.

  15. Current trends in staging rectal cancer

    Abdus Samee; Chelliah Ramachandran Selvasekar


    Management of rectal cancer has evolved over the years.In this condition preoperative investigations assist in deciding the optimal treatment.The relation of the tumor edge to the circumferential margin (CRM) is an important factor in deciding the need for neoadjuvant treatment and determines the prognosis.Those with threatened or involved margins are offered long course chemoradiation to enable R0 surgical resection.Endoanal ultrasound (EUS) is useful for tumor (T) staging;hence EUS is a useful imaging modality for early rectal cancer.Magnetic resonance imaging (MRI) is useful for assessing the mesorectum and the mesorectal fascia which has useful prognostic significance and for early identification of local recurrence.Computerized tomography (CT) of the chest,abdomen and pelvis is used to rule out distant metastasis.Identification of the malignant nodes using EUS,CT and MRI is based on the size,morphology and internal characteristics but has drawbacks.Most of the common imaging techniques are suboptimal for imaging following chemoradiation as they struggle to differentiate fibrotic changes and tumor.In this situation,EUS and MRI may provide complementary information to decide further treatment.Functional imaging using positron emission tomography (PET) is useful,particularly PET/CT fusion scans to identify areas of the functionally hot spots.In the current state,imaging has enabled the multidisciplinary team of surgeons,oncologists,radiologists and pathologists to decide on the patient centered management of rectal cancer.In future,functional imaging may play an active role in identifying patients with lymph node metastasis and those with residual and recurrent disease following neoadjuvant chemoradiotherapy.

    Chang, Sei Kyung; Kim, Jong Woo; Oh, Do Yeun; Chong, So Young; Shin, Hyun Soo [Bundang CHA General Hospital, Pochon CHA University, Seongnam (Korea, Republic of)


    To evaluate the role of postoperative adjuvant chemoradiotherapy in rectal cancer, we retrospectively analyzed the treatment outcome of patients with rectal cancer taken curative surgical resection and postoperative adjuvant chemoradiotherapy. A total 46 patients with AJCC stage II and III carcinoma of rectum were treated with curative surgical resection and postoperative adjuvant chemoradiotherapy. T3 and T4 stage were 38 and 8 patients, respectively. N0, N1, and N2 stage were 12, 16, 18 patients, respectively. Forty patients received bolus infusions of 5-fluorouracil (500 mg/m{sup 2}/day) with leucovorin (20 mg/m{sup 2}/day), every 4 weeks interval for 6 cycles. Oral Uracil/Tegafur on a daily basis for 6 {approx} 12 months was given in 6 patients. Radiotherapy with 45 Gy was delivered to the surgical bed and regional pelvic lymph node area, followed by 5.4 {approx} 9 Gy boost to the surgical bed. The follow up period ranged from 8 to 75 months with a median 35 months. Treatment failure occurred in 17 patients (37%). Locoregional failure occurred in 4 patients (8.7%) and distant failure in 16 patients (34.8%). There was no local failure only. Five year actuarial overall survival (OS) was 51.5% and relapse free survival (RFS) was 58.7%. The OS and RFS were 100%, 100% in stage N0 patients, 53.7%, 47.6% in N1 patients, and 0%, 41.2% in N2 patients ({rho} = 0.012, {rho} = 0.009). The RFS was 55%, 78.5%, and 31.2% in upper, middle, and lower rectal cancer patients, respectively ({rho} = 0.006). Multivariate analysis showed that N stage ({rho} = 0.012) was significant prognostic factor for OS and that N stage ({rho} = 0.001) and location of tumor ({rho} = 0.006) were for RFS. Bowel complications requiring surgery occurred in 3 patients. Postoperative adjuvant chemoradiotherapy was an effective modality for locoregional control of rectal cancer. But further investigations for reducing the distant failure rate are necessary because distant failure rate is still high.

  18. Rectal and appendiceal inflammatory myofibroblastic tumors.

    Khoddami, Maliheh; Sanae, Shahram; Nikkhoo, Bahram


    Inflammatory myofibroblastic tumors are neoplasms characterized by spindle cell proliferation and a fiboinflammatory vascular stroma. Herein, we presented the successful treatment of a rectal inflammatory myofibroblastic tumor in an 11-year-old boy who presented with diarrhea and abdominal pain of 1(1/2) months duration and an appendiceal inflammatory myofibroblastic tumor in a 29-year-old man presented with recurrent abdominal pain of two months duration with associated tenderness and rebound tenderness in the right lower abdomen. Histologically, our cases had inflammatory myofibroblastic tumors very similar to that of other sites; the spindle cells were positive for vimentin and muscle-specific actin.

  19. Invasive amebiasis and ameboma formation presenting as a rectal mass: An uncommon case of malignant masquerade at a western medical center


    A 54-year-old man presented with rectal pain and bleeding secondary to ulcerated, necrotic rectal and cecal masses that resembled colorectal carcinoma upon colonoscopy. These masses were later determined to be benign amebomas caused by invasive Entamoeba histolytica, which regressed completely with medical therapy. In Western countries, the occurrence of invasive protozoan infection with formation of amebomas is very rare and can mistakenly masquerade as a neoplasm. Not surprisingly, there have been very few cases reported of this clinical entity within the United States. Moreover, we report a patient that had an extremely rare occurrence of two synchronous lesions, one involving the rectum and the other situated in the cecum. We review the current literature on the pathogenesis of invasive E. Histolytica infection and ameboma formation, as well as management of this rare disease entity at a western medical center.

  6. Tranexamic acid in the management of upper gastrointestinal bleeding: an evidence-based case report.

    Atikah, Nur; Singh, Gurmeet; Maulahela, Hasan; Cahyanur, Rahmat


    to review the effectiveness of tranexamic acid therapy which has been proposed to reduce bleeding and in turn lower mortality rate. following literature searching based on our clinical question on Cochrane Library, PubMed, Clinical Key, EBSCO, Science Direct and Proquest, one systematic review that includes seven randomized controlled trials is obtained. The article meets validity and relevance criteria. the systematic review found that there is no any clear evidence between intervention and control groups in term of mortality. the use of tranexamic acid to reduce mortality in patients with upper gastrointestinal bleeding is not recommended.

  7. Intracranial hemorrhage in congenital bleeding disorders.

    Tabibian, Shadi; Motlagh, Hoda; Naderi, Majid; Dorgalaleh, Akbar


    : Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death. This bleeding feature can also be observed in grey platelet syndrome, though less frequently than in Glanzmann's thrombasthenia. In hemophilia, intracerebral hemorrhage is affected by various risk factors one of which is the severity of the disease. The precise prevalence of ICH in these patients is not clear but an estimated incidence of 3.5-4% among newborns with hemophilia is largely ascertained. Although ICH is a rare phenomenon in CBDs, it can be experienced by every patient with severe hemophilia A and B, FXIII deficiency (FXIIID), FVIID, FXD, FVD, FIID, and afibrinogenemia. Upon observing the general signs and symptoms of ICH such as vomiting, seizure, unconsciousness, and headache, appropriate replacement therapies and cranial ultrasound scans must be done to decrease ICH-related morbidity and mortality.

  8. Immunological Landscape and Clinical Management of Rectal Cancer

    Elísabeth ePérez-Ruiz


    Full Text Available The clinical management of rectal cancer and colon cancer differs due to increased local relapses in rectal cancer. However, the current molecular classification does not differentiate rectal cancer and colon cancer as two different entities. In recent years, the impact of the specific immune microenvironment in cancer has attracted renewed interest, and is currently recognized as one of the major determinants of clinical progression in a wide range of tumors. In colorectal cancer, the density of lymphocytic infiltration is associated with better overall survival. Due to the need for biomarkers of response to conventional treatment with chemoradiotherapy in rectal tumors, the immune status of rectal cancer emerges as a useful tool to improve the management of patients.

  9. Intraoperative radiotherapy in primary rectal cancer; Intraoperative Radiotherapie des primaeren Rektumkarzinoms

    Mund, Christian


    According to the results of several studies intraoperative radiotherapy seems to influence local control for primary rectal cancer in UICC-Stage II / III positively, though recommendations in therapy cannot be given as studies of high evidence level do not exist. As IORT is rarely available and makes patient recruitment difficult, prospective randomised trials have not been carried out yet. This emphasizes the importance of non-randomised trials for an evaluation of IORT. A comparison of 21 patients with locally advanced rectal cancer who had been treated with intraoperative radiation therapy and 21 similar cases without an application of IORT could not show any significant improvements in prognosis (recurrences, metastases and disease-specific survival). Nevertheless the employment of intraoperative radiation showed a trend in improvement of local control. This hast been shown by several other studies before. Thus the application of IORT in patients with locally advanced rectal cancer is considered a useful part in multimodal treatment and should further be evaluated in specialized centres. In case-control studies 1:1-matching leads to a good comparability of groups and renders conclusions of high internal validity possible. To gain a sufficient power, this type of trials should however primarily be carried out by centres with a high number of cases.

  10. A simplified clinical risk score predicts the need for early endoscopy in non-variceal upper gastrointestinal bleeding.

    Tammaro, Leonardo; Buda, Andrea; Di Paolo, Maria Carla; Zullo, Angelo; Hassan, Cesare; Riccio, Elisabetta; Vassallo, Roberto; Caserta, Luigi; Anderloni, Andrea; Natali, Alessandro


    Pre-endoscopic triage of patients who require an early upper endoscopy can improve management of patients with non-variceal upper gastrointestinal bleeding. To validate a new simplified clinical score (T-score) to assess the need of an early upper endoscopy in non variceal bleeding patients. Secondary outcomes were re-bleeding rate, 30-day bleeding-related mortality. In this prospective, multicentre study patients with bleeding who underwent upper endoscopy were enrolled. The accuracy for high risk endoscopic stigmata of the T-score was compared with that of the Glasgow Blatchford risk score. Overall, 602 patients underwent early upper endoscopy, and 472 presented with non-variceal bleeding. High risk endoscopic stigmata were detected in 145 (30.7%) cases. T-score sensitivity and specificity for high risk endoscopic stigmata and bleeding-related mortality was 96% and 30%, and 80% and 71%, respectively. No statistically difference in predicting high risk endoscopic stigmata between T-score and Glasgow Blatchford risk score was observed (ROC curve: 0.72 vs. 0.69, p=0.11). The two scores were also similar in predicting re-bleeding (ROC curve: 0.64 vs. 0.63, p=0.4) and 30-day bleeding-related mortality (ROC curve: 0.78 vs. 0.76, p=0.3). The T-score appeared to predict high risk endoscopic stigmata, re-bleeding and mortality with similar accuracy to Glasgow Blatchford risk score. Such a score may be helpful for the prediction of high-risk patients who need a very early therapeutic endoscopy. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

METHODS: Male Wistar albino rats weighing 250-300 g were divided into four groups: Group S (n = 8 was a sham group that served as a baseline for the normal basal values; Group C (n = 8 consisted of rats that received the rectal application of saline alone; Group IPDex (n = 8 included rats that received the intraperitoneal application of dexmedetomidine (100 µg kg-1; and Group RecDex (n = 8 included rats that received the rectal application of dexmedetomidine (100 µg kg-1. For the rectal drug administration, we used 22 G intravenous cannulas with the stylets removed. We administered the drugs by advancing the cannula 1 cm into the rectum, and the rectal administration volume was 1 mL for all the rats. The latency and anesthesia time (min were measured. Two hours after rectal administration, 75 mg kg-1 ketamine was administered for intraperitoneal anesthesia in all the groups, followed by the removal of the rats' rectums to a distal distance of 3 cm via an abdominoperineal surgical procedure. We histopathologically examined and scored the rectums. RESULTS: Anesthesia was achieved in all the rats in the Group RecDex following the administration of dexmedetomidine. The onset of anesthesia in the Group RecDex was significantly later and of a shorter duration than in the Group IPDEx (p < 0.05. In the Group RecDex, the administration of dexmedetomidine induced mild-moderate losses of mucosal architecture in the colon and rectum, 2 h after rectal inoculation. CONCLUSION: Although 100 µg kg-1 dexmedetomidine administered rectally to rats achieved a significantly longer duration of anesthesia compared with the rectal administration of saline, our histopathological evaluations showed that the rectal administration of 100 µg kg-1 dexmedetomidine led to mild-moderate damage to the mucosal structure of the

  12. Comparison of rectal and axillary temperatures in dogs and cats.

    Goic, Joana B; Reineke, Erica L; Drobatz, Kenneth J


    To compare rectal versus axillary temperatures in dogs and cats. Prospective observational study. 94 dogs and 31 cats. Paired axillary and rectal temperatures were measured in random order with a standardized method. Animal signalment, initial complaint, blood pressure, blood lactate concentration, and variables associated with vascular perfusion and coat were evaluated for associations with axillary and rectal temperatures. Axillary temperature was positively correlated with rectal temperature (ρ = 0.75 in both species). Median axillary temperature (38.4°C [101.1°F] in dogs, and 38.4°C [101.2°F] in cats) was significantly different from median rectal temperature in dogs (38.9°C [102.0°F]) but not in cats (38.6°C [101.5°F]). Median rectal-axillary gradient (difference) was 0.4°C (0.7°F; range, -1.3° to 2.3°C [-2.4° to 4.1°F]) in dogs and 0.17°C (0.3°F; range -1.1° to 1.6°C [-1.9° to 3°F]) in cats. Sensitivity and specificity for detection of hyperthermia with axillary temperature were 57% and 100%, respectively, in dogs and 33% and 100%, respectively, in cats; sensitivity and specificity for detection of hypothermia were 86% and 87%, respectively, in dogs and 80% and 96%, respectively, in cats. Body weight (ρ = 0.514) and body condition score (ρ = 0.431) were correlated with rectal-axillary gradient in cats. Although axillary and rectal temperatures were correlated in dogs and cats, a large gradient was present between rectal temperature and axillary temperature, suggesting that axillary temperature should not be used as a substitute for rectal temperature.

  13. [Neoadjuvant and surgical treatment for rectal cancer].

    Rödel, Claus; Knoefel, Wolfram Trudo; Schlitt, Hans J; Staib, Ludger; Höhler, Thomas


    According to the 2008 guidelines on colorectal cancer, whether preoperative therapy is indicated for rectal cancer should be judged based on the T and N categories. A few centres limit the indication for preoperative radio(chemo)therapy to patients with tumours that, according to magnetic resonance tomography (MRT), extend to the fascia mesorectalis or are 1 mm or less away from it - so-called circumferential resection margin-positive or CRM-positive tumours. Omitting preoperative therapy for MRT CRM-negative tumours is, however, a matter that still requires further study in clinical trials. The high rate of distant metastases continues to be a problem. Assuming that pathohistological complete remission (pCR) is a predictive marker of long-term disease-free survival after neoadjuvant radiochemotherapy, attempts are now being undertaken to intensify the neoadjuvant therapy. Phase II trials show improved pCR rates by combining the preoperative radiation with the double combinations oxaliplatin or irinotecan plus infusional or oral 5-FU (capecitabine). In the case of limited T1 rectal cancer without further risk factors, transanal local excision can be used.

  14. Fibrinogen concentrate for bleeding - a systematic review

    Lunde, J; Stensballe, J; Wikkelsø, A


    Fibrinogen concentrate as part of treatment protocols increasingly draws attention. Fibrinogen substitution in cases of hypofibrinogenaemia has the potential to reduce bleeding, transfusion requirement and subsequently reduce morbidity and mortality. A systematic search for randomised controlled...... trials (RCTs) and non-randomised studies investigating fibrinogen concentrate in bleeding patients was conducted up to November 2013. We included 30 studies of 3480 identified (7 RCTs and 23 non-randomised). Seven RCTs included a total of 268 patients (165 adults and 103 paediatric), and all were...... determined to be of high risk of bias and none reported a significant effect on mortality. Two RCTs found a significant reduction in bleeding and five RCTs found a significant reduction in transfusion requirements. The 23 non-randomised studies included a total of 2825 patients, but only 11 of 23 studies...

  15. Small intestine bleeding due to multifocal angiosarcoma

    Luisa Zacarias F(o)ohrding; Arne Macher; Stefan Braunstein; Wolfram Trudo Knoefel; Stefan Andreas Topp


    We report a case of an 84-year-old male patient with primary small intestinal angiosarcoma.The patient initially presented with anemia and melena.Consecutive endoscopy revealed no signs of upper or lower active gastrointestinal bleeding.The patient had been diagnosed 3 years previously with an aortic dilation,which was treated with a stent.Computed tomography suggested an aorto-intestinal fistula as the cause of the in-testinal bleeding,leading to operative stent explantation and aortic replacement.However,an aorto-intestinal fistula was not found,and the intestinal bleeding did not arrest postoperatively.The constant need for blood transfusions made an exploratory laparotomy imperative,which showed multiple bleeding sites,predominately in the jejunal wall.A distal loop jejunostomy was conducted to contain the small intestinal bleeding and a segmental resection for histological evaluation was performed.The histological analysis revealed a lessdifferentiated tumor with characteristic CD31,cytokeratin,and vimentin expression,which led to the diagnosis of small intestinal angiosarcoma.Consequently,the infiltrated part of the jejunum was successfully resected in a subsequent operation,and adjuvant chemotherapy with paclitaxel was planned.Angiosarcoma of the small intestine is an extremely rare malignant neoplasm that presents with bleeding and high mortality.Early diagnosis and treatment are essential to improve outcome.A small intestinal angiosarcoma is a challenging diagnosis to make because of its rarity,nonspecific symptoms of altered intestinal function,nonspecific abdominal pain,severe melena,and acute abdominal signs.Therefore,a quick clinical and histological diagnosis and decisive measures including surgery and adjuvant chemotherapy should be the aim.

    Solitary rectal ulcer syndrome is a rare clinical entity. Several treatment options has been described. However, there is no consensus yet on treatment algorithm and standard surgical procedure. Rectopexy is one of the surgical options and it is generally performed in patients with solitary rectal ulcer accompanied with overt prolapse. Various outcomes have been reported for rectopexy in the patients with occult prolapse or rectal intussusception. In the literature; outcomes of laparoscopic non-resection rectopexy procedure have been reported in the limited number of case or case series. No study has emphasized the outcomes of laparoscopic non-resection rectopexy procedure in the patients with solitary rectal ulcer without overt prolapse. In this report we aimed to present clinical outcomes of laparoscopic non-resection posterior suture rectopexy procedure in a 21-year-old female patient with solitary rectal ulcer without overt prolapse.

  18. The Approach to Occult Gastrointestinal Bleed.

    Naut, Edgar R


    Occult gastrointestinal bleeding is not visible and may present with a positive fecal occult blood test or iron deficiency anemia. Obscure bleeding can be overt or occult, with no source identified despite an appropriate diagnostic workup. A stepwise approach to this evaluation after negative upper and lower endoscopy has been shown to be cost effective. This includes repeat endoscopies if warranted, followed by video capsule endoscopy (VCE) if no obstruction is present. If the VCE is positive then specific endoscopic intervention may be possible. If negative, patients may undergo either repeat testing or watchful waiting with iron supplements. Copyright © 2016 Elsevier Inc. All rights reserved.

    Gaudong Mbethe, G L; Mounguengui, D; Ondounda, M; Magne, C; Bignoumbra, R; Ntsoumou, S; Moussavou Kombila, J-B; Nzenze, J R


    The department of internal medicine of the military hospital of Gabon managed 92 cases of upper gastrointestinal bleeding from April 2009 to November 2011. The frequency of these hemorrhages in the department was 8.2%; they occurred most often in adults aged 30-40 years and 50-60 years, and mainly men (74%). Erosive-ulcerative lesions (65.2%) were the leading causes of hemorrhage, followed by esophageal varices (15.2%). These results underline the importance of preventive measures for the control of this bleeding.

  20. Acid inhibition and peptic ulcer bleeding.

    Štimac, D; Franjić, N; Krznarić, Ž


    Peptic ulcer bleeding is one of the most common emergency situations in medicine. Combined pharmacological and endoscopic therapy together with emerging interventional radiological procedures are successfully treating peptic ulcer disease, reserving surgical procedures for only a small portion of patients unresponsive to 'conventional' therapy. Technological advancement has seen a great improvement in the field of endoscopic treatment in the form of various methods of hemostasis. However, pharmacological therapy with proton pump inhibitors still plays the central role in the peptic ulcer bleeding treatment algorithm.

  1. Rectal HSV-2 Infection May Increase Rectal SIV Acquisition Even in the Context of SIVΔnef Vaccination.

    Guerra-Pérez, Natalia; Aravantinou, Meropi; Veglia, Filippo; Goode, Diana; Truong, Rosaline; Derby, Nina; Blanchard, James; Grasperge, Brooke; Gettie, Agegnehu; Robbiani, Melissa; Martinelli, Elena


    Prevalent HSV-2 infection increases the risk of HIV acquisition both in men and women even in asymptomatic subjects. Understanding the impact of HSV-2 on the mucosal microenvironment may help to identify determinants of susceptibility to HIV. Vaginal HSV-2 infection increases the frequency of cells highly susceptible to HIV in the vaginal tissue of women and macaques and this correlates with increased susceptibility to vaginal SHIV infection in macaques. However, the effect of rectal HSV-2 infection on HIV acquisition remains understudied. We developed a model of rectal HSV-2 infection in macaques in combination with rectal SIVmac239Δnef (SIVΔnef) vaccination and our results suggest that rectal HSV-2 infection may increase the susceptibility of macaques to rectal SIVmac239 wild-type (wt) infection even in SIVΔnef-infected animals. Rectal SIVΔnef infection/vaccination protected 7 out of 7 SIVΔnef-infected macaques from SIVmac239wt rectal infection (vs 12 out of 16 SIVΔnef-negative macaques), while 1 out of 3 animals co-infected with SIVΔnef and HSV-2 acquired SIVmac239wt infection. HSV-2/SIVmac239wt co-infected animals had increased concentrations of inflammatory factors in their plasma and rectal fluids and a tendency toward higher acute SIVmac239wt plasma viral load. However, they had higher blood CD4 counts and reduced depletion of CCR5+ CD4+ T cells compared to SIVmac239wt-only infected animals. Thus, rectal HSV-2 infection generates a pro-inflammatory environment that may increase susceptibility to rectal SIV infection and may impact immunological and virological parameters during acute SIV infection. Studies with larger number of animals are needed to confirm these findings.

    Risk stratification systems that accurately identify patients with a high risk for bleeding through the use of clinical predictors of mortality before endoscopic examination are needed. Computerized (artificial) neural networks (ANNs) are adaptive tools that may improve prognostication. To assess the capability of an ANN to predict mortality in patients with nonvariceal upper GI bleeding and compare the predictive performance of the ANN with that of the Rockall score. Prospective, multicenter study. Academic and community hospitals. This study involved 2380 patients with nonvariceal upper GI bleeding. Upper GI endoscopy. The primary outcome variable was 30-day mortality, defined as any death occurring within 30 days of the index bleeding episode. Other outcome variables were recurrent bleeding and need for surgery. We performed analysis of certified outcomes of 2380 patients with nonvariceal upper GI bleeding. The Rockall score was compared with a supervised ANN (TWIST system, Semeion), adopting the same result validation protocol with random allocation of the sample in training and testing subsets and subsequent crossover. Overall, death occurred in 112 cases (4.70%). Of 68 pre-endoscopic input variables, 17 were selected and used by the ANN versus 16 included in the Rockall score. The sensitivity of the ANN-based model was 83.8% (76.7-90.8) versus 71.4% (62.8-80.0) for the Rockall score. Specificity was 97.5 (96.8-98.2) and 52.0 (49.8 4.2), respectively. Accuracy was 96.8% (96.0-97.5) versus 52.9% (50.8-55.0) (Pbleeding and obscure GI hemorrhage are excluded. In patients with nonvariceal upper GI bleeding, ANNs are significantly superior to the Rockall score in predicting the risk of death. Copyright © 2011 American Society for Gastrointestinal Endoscopy.

  3. Prognostic nomograms for predicting survival and distant metastases in locally advanced rectal cancers.

    Junjie Peng

    Full Text Available To develop prognostic nomograms for predicting outcomes in patients with locally advanced rectal cancers who do not receive preoperative treatment.A total of 883 patients with stage II-III rectal cancers were retrospectively collected from a single institution. Survival analyses were performed to assess each variable for overall survival (OS, local recurrence (LR and distant metastases (DM. Cox models were performed to develop a predictive model for each endpoint. The performance of model prediction was validated by cross validation and on an independent group of patients.The 5-year LR, DM and OS rates were 22.3%, 32.7% and 63.8%, respectively. Two prognostic nomograms were successfully developed to predict 5-year OS and DM-free survival rates, with c-index of 0.70 (95% CI = [0.66, 0.73] and 0.68 (95% CI = [0.64, 0.72] on the original dataset, and 0.76 (95% CI = [0.67, 0.86] and 0.73 (95% CI = [0.63, 0.83] on the validation dataset, respectively. Factors in our models included age, gender, carcinoembryonic antigen value, tumor location, T stage, N stage, metastatic lymph nodes ratio, adjuvant chemotherapy and chemoradiotherapy. Predicted by our nomogram, substantial variability in terms of 5-year OS and DM-free survival was observed within each TNM stage category.The prognostic nomograms integrated demographic and clinicopathological factors to account for tumor and patient heterogeneity, and thereby provided a more individualized outcome prognostication. Our individualized prediction nomograms could help patients with preoperatively under-staged rectal cancer about their postoperative treatment strategies and follow-up protocols.

  4. Gracilis muscle interposition with primary rectal without urethral repair for moderate sized rectourethral fistula caused by brachytherapy for prostate cancer: a case report

    Samalavicius Narimantas


    Full Text Available Abstract Introduction There is a 0.16% chance of a rectourethral fistula after prostate brachytherapy monotherapy using Palladium-103 or Iodine-125 implants. We present an unusual case report of a rectourethral fistula following brachyradiotherapy monotherapy for prostate adenocarcinoma. It was also associated with unusual management of the fistula. Case presentation A 58-year-old Caucasian man underwent brachyradiotherapy monotherapy as definitive treatment for verified intracapsular prostate adenocarcinoma receiving 56 Iodine-125 implants using a transrectal ultrasound-guided technique. The patient started to complain of severe perineal pain and mild rectal bleeding 15Â months after brachyradiotherapy. A biopsy of mucosa of his anterior rectal wall was performed. A moderate sized rectourethral fistula was confirmed 23Â months after implantation of Iodine-125 seeds. Laparoscopic sigmoidostomy and suprapubic cystostomy were then performed. Long-term cortisone applications in combination with 30 sessions of hyperbaric oxygen therapy, and antibacterial therapies were initiated due to necrotic infection. A gracilis muscle interposition to create a partition between the patient's rectum and urethra in conjunction with primary rectal repair but without urethral repair were performed 6 months later. The 3cm rectal defect was repaired via a 3cm-long horizontal perineal incision. The 1.5cm urethral defect just below the prostate was not repaired. The patient underwent an optic internal urethrotomy 3Â months later for a 1.5cm-long urethral stricture. Several planned preventive urethral buginages were performed to avoid urethral stricture recurrence. At 12Â months postoperatively, there were no signs of a fistula and cancer recurrence. He now has a normal voiding and anal continence. Conclusion Severe rectal pain, bleeding, and local anterior necrotic proctitis are predictors of a rectourethral fistula. Urinary and fecal diversion is the first

    L after treatment with COMP-RCS. Seven studies fulfilled the inclusion criteria. Different aspects of HRQoL seemed to be impaired for a shorter or longer period of time after surgery, in disease free patients treated for PARC and LRRC. However, the included studies all had methodological problems, which...... in the study was 164 (86%) patients treated with standard rectal cancer surgery (STAN-RCS). The Danish version showed satisfactory psychometric properties for the scales concerning body image, sexual functioning, male sexual problems and defecations problems. Reduced psychometric properties were found....... The majority of the scales improved or remained stable during the first year after surgery, a decrease was seen only for body image. One year after surgery HRQoL in patients with COMP-RSC was comparable to patients with STAN-RCS and NORM-data with exception of a poorer physical and emotional role function...

  6. Numerical simulation of base flow with hot base bleed for two jet models

    Wen-jie YU; Yong-gang YU; Bin NI


    In order to improve the benefits of base bleed in base flow field, the base flow with hot base bleed for two jet models is studied. Two-dimensional axisymmetric NaviereStokes equations are computed by using a finite volume scheme. The base flow of a cylinder afterbody with base bleed is simulated. The simulation results are validated with the experimental data, and the experimental results are well reproduced. On this basis, the base flow fields with base bleed for a circular jet model and an annulus jet model are investigated by selecting the injection temperature from 830 K to 2200 K. The results show that the base pressure of the annular jet model is higher than that of the circular jet model with the changes of the injection parameter and the injection temperature. For the circular jet model, the hot gases are concentrated in the vicinity of the base. For the annular jet model, the bleed gases flow into the shear layer directly so that the hot gases are concentrated in the shear layer. The latter temperature distribution is better for the increase of base pressure.

  7. Platelet dysfunction in thrombosis patients treated with vitamin K antagonists and recurrent bleeding.

    Paola E J van der Meijden

    Full Text Available BACKGROUND: Recurrent bleeding can complicate the treatment of thrombosis patients with vitamin K antagonists (VKA, even at a well-regulated level of anticoagulation. In this proof-of-principle study, we investigated whether alterations in platelet function or von Willebrand factor (vWf contribute to a bleeding phenotype in these patients. METHODS: In this case-control study 33 well-regulated patients without bleeding events (controls and 33 patients with recurrent bleeding (cases were retrospectively included. Thrombin generation and vWf were determined in plasma. Platelet function was assessed by light transmission aggregometry and flow cytometry using a validated panel of agonists. RESULTS: Thrombin generation was similarly reduced in controls and cases, in comparison to normal plasma. Plasma vWf level was above the normal range in 85% of controls and 67% of the cases. vWf activity was similarly increased in all patients in comparison to healthy volunteers. Platelet aggregation was in the normal range for almost all patients irrespective of the type of agonist. However, in response to a low collagen dose, platelets from 21% of controls and 27% of cases showed diminished responses. Agonist-induced secretion of alpha- and dense-granules or integrin αIIbβ3 activation were affected in platelets from neither controls nor cases. CONCLUSION: Recurrent bleeding in well-controlled patients on VKA therapy is not explained by anti-hemostatic changes in platelet or vWf function.

  8. Diagnosis of gastrointestinal bleeding: A practical guide for clinicians

    Kim, Bong Sik Matthew; Li, Bob T; Engel, Alexander; Samra, Jaswinder S; Clarke, Stephen; Norton, Ian D; Li, Angela E


    Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is not apparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians. PMID:25400991

  9. Management of Upper Gastrointestinal Bleeding in Children: Variceal and Nonvariceal.

    Lirio, Richard A


    Upper gastrointestinal (UGI) bleeding is generally defined as bleeding proximal to the ligament of Treitz, which leads to hematemesis. There are several causes of UGI bleeding necessitating a detailed history to rule out comorbid conditions, medications, and possible exposures. In addition, the severity, timing, duration, and volume of the bleeding are important details to note for management purposes. Despite the source of the bleeding, acid suppression with a proton-pump inhibitor has been shown to be effective in minimizing rebleeding. Endoscopy remains the interventional modality of choice for both nonvariceal and variceal bleeds because it can be diagnostic and therapeutic. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Acute postoperative pain has adverse effects on the patients moral as well as various physiological functions of the body. We conducted a prospective randomized study to compare the efficacy of preoperative rectal diclofenac and paracetamol for postoperative analgesia in pediatric age group. Sixty children (3 – 13 yrs. undergoing minor surgical procedures were randomly alloc ated into 2 groups, group I comprising of 30 children who received diclofenac suppository post induction and group II comprising of 30 children who received paracetamol suppository post induction. Pain was assessed by the “Hanallah pain scale” which catego rizes pain based on 5 parameters, viz, systolic blood pressure, crying, movements, agitation (confused, excited, and complaints of pain 1 . We concluded that though both, diclofenac sodium and paracetamol are good postoperative analgesics when given by rect al route in pediatric patients undergoing minor surgeries, diclofenac sodium provides better analgesia than paracetamol when given by rectal route in pediatric patients.

  12. Duodenal variceal bleed: an unusual cause of upper gastrointestinal bleed and a difficult diagnosis to make.

    Bhagani, Shradha; Winters, Conchubhair; Moreea, Sulleman


    We present a case of recurrent upper gastrointestinal (GI) bleeding in a man aged 57 years with primary biliary cholangitis who was ultimately diagnosed with an isolated duodenal variceal bleed, which was successfully treated with histoacryl glue injection. Duodenal varices are an uncommon presentation of portal hypertension and can result in significant GI bleeding with a high mortality. Diagnosis can be difficult and therapeutic options limited. Endoscopic variceal sclerotherapy with histoacryl glue provides an effective treatment, though endoscopists need to remain aware of and vigilant for the serious complications of this treatment option. 2017 BMJ Publishing Group Ltd.

  14. Rectal and colon cancer: Not just a different anatomic site.

    Tamas, K; Walenkamp, A M E; de Vries, E G E; van Vugt, M A T M; Beets-Tan, R G; van Etten, B; de Groot, D J A; Hospers, G A P


    Due to differences in anatomy, primary rectal and colon cancer require different staging procedures, different neo-adjuvant treatment and different surgical approaches. For example, neoadjuvant radiotherapy or chemoradiotherapy is administered solely for rectal cancer. Neoadjuvant therapy and total mesorectal excision for rectal cancer might be responsible in part for the differing effect of adjuvant systemic treatment on overall survival, which is more evident in colon cancer than in rectal cancer. Apart from anatomic divergences, rectal and colon cancer also differ in their embryological origin and metastatic patterns. Moreover, they harbor a different composition of drug targets, such as v-raf murine sarcoma viral oncogene homolog B (BRAF), which is preferentially mutated in proximal colon cancers, and the epidermal growth factor receptor (EGFR), which is prevalently amplified or overexpressed in distal colorectal cancers. Despite their differences in metastatic pattern, composition of drug targets and earlier local treatment, metastatic rectal and colon cancer are, however, commonly regarded as one entity and are treated alike. In this review, we focused on rectal cancer and its biological and clinical differences and similarities relative to colon cancer. These aspects are crucial because they influence the current staging and treatment of these cancers, and might influence the design of future trials with targeted drugs.

  15. Accurate triage of lower gastrointestinal bleed (LGIB) - A cohort study.

    Chong, Vincent; Hill, Andrew G; MacCormick, Andrew D


    Acute lower gastrointestinal bleeding (LGIB) is a common acute presenting complaint to hospital. Unlike upper gastrointestinal bleeding, the diagnostic and therapeutic approach is not well-standardised. Intensive monitoring and urgent interventions are essential for patients with severe LGIB. The aim of this study is to investigate factors that predict severe LGIB and develop a clinical predictor tool to accurately triage LGIB in the emergency department of a busy metropolitan teaching hospital. We retrospectively identified all adult patients who presented to Middlemore Hospital Emergency Department with LGIB over a one year period. We recorded demographic variables, Charlson Co-morbidities Index, use of anticoagulation, examination findings, vital signs on arrival, laboratory test results, treatment plans and further investigations results. We then identified a subgroup of patients who suffered severe LGIB. A total of 668 patients presented with an initial triage diagnosis of LGIB. 83 of these patients (20%) developed severe LGIB. Binary logistic regression analysis identified four independent risk factors for severe LGIB: use of aspirin, history of collapse, haemoglobin on presentation of less than 100 mg/dl and albumin of less than 38 g/l. We have developed a clinical prediction tool for severe LGIB in our population with a negative predictive value (NPV) of 88% and a positive predictive value (PPV) of 44% respectively. We aim to validate the clinical prediction tool in a further cohort to ensure stability of the multivariate model. Copyright © 2015. Published by Elsevier Ltd.

    Pectic ulcer is the most frequent cause of gastrointestinal bleeding. The homeostatic mechanism of bleeding, and coagulation, does not happen with values of pH less than 5,0. Therefore neutralization of gastric acidity (pH more than 5,0) is a recourse of control, improve the evolution and healing of peptic ulcer and to avoid a new bleeding. The aim of this study was to compare the results of treatment with omeprazole and ranitidine, in 57 patients admitted at emergency room of the Hospital Central de la Polic a Nacional del Per with endoscopic diagnosis of peptic ulcer, using Forrest classification. Patients received omeprazole 40 mg in bolus IV, followed by continuos infusion of 8 mg/hour for 72 hours (group A) or ranitidine 50 mg IV each 8 hours for 72 hours (group B). A new endoscopy was made 72 hours after admission demostrated a succesful therapy in both group. Bleeding stopped in 26/27 patients in group A (96,2%) and in 23/30 patients in group B (76,6%) (pomeprazole IV is more effective than ranitidine IV in the control of UGB because of peptic ulcer and provides a faster healing.

    Upper gastrointestinal (UGI) bleeding secondary to ulcer disease occurs commonly and results in significant patient morbidity and medical expense. After initial resuscitation, carefully performed endoscopy provides an accurate diagnosis of the source of the UGI hemorrhage and can reliably identify those high-risk subgroups that may benefit most from endoscopic hemostasis. Large channel therapeutic endoscopes are recommended. Endoscopists should be very experienced in management of patients with UGI hemorrhage including the use of various hemostatic devices. For patients with major stigmata of ulcer hemorrhage – active arterial bleeding, non-bleeding visible vessel and adherent clot – combination therapy with epinephrine injection and either thermal coaptive coagulation (with multipolar or heater probe), or endoclips is recommended. High dose intravenous proton pump inhibitors are recommended as concomitant therapy with endoscopic hemostasis of major stigmata. Patients with minor stigmata or clean-based ulcers will not benefit from endoscopic therapy and should be triaged to less intensive care and be considered for early discharge. Effective endoscopic hemostasis of ulcer bleeding can significantly improve outcomes by reducing rebleeding, transfusion requirement, and need for surgery, as well as reduce cost of medical care.

  20. Systemic causes of heavy menstrual bleeding

    Verschueren, Sophie


    Heavy menstrual bleeding (HMB) is a common problem in fertile women. In addition to local factors, such as a polyp or a uterine fibroid, systemic causes may lead to HMB. These systemic causes are discussed in this thesis. For years, women with HMB were tested underlying thyroid disorder, but our res

  1. Italian Registry of Congenital Bleeding Disorders

    Giampaolo, Adele; Abbonizio, Francesca; Arcieri, Romano; Hassan, Hamisa Jane


    In Italy, the surveillance of people with bleeding disorders is based on the National Registry of Congenital Coagulopathies (NRCC) managed by the Italian National Institute of Health (Istituto Superiore di Sanità). The NRCC collects epidemiological and therapeutic data from the 54 Hemophilia Treatment Centers, members of the Italian Association of Hemophilia Centres (AICE). The number of people identified with bleeding disorders has increased over the years, with the number rising from approx. 7000 in 2000 to over 11,000 in 2015. The NRCC includes 4020 patients with hemophilia A and 859 patients with hemophilia B. The prevalence of the rare type 3 vWD is 0.20/100,000 inhabitants. Less common congenital bleeding disorders include the following deficiencies: Factor I (fibrinogen), Factor II (prothrombin), Factor V, Factor VII, Factor X, Factor XI and Factor XIII, which affect 1953 patients. Hepatitis C Virus (HCV) infection affects 1561 patients, more than 200 of whom have two infections (HCV + HIV). Estimated hemophilia-related drug consumption in 2015 was approx. 550 million IU of FVIII for hemophilia A patients and approx. 70 million IU of FIX for hemophilia B patients. The NRCC, with its bleeding disorder data set, is a tool that can provide answers to fundamental questions in public health, monitoring care provision and drug treatment, as well as facilitating clinical and epidemiological research.

  2. Pre-referral rectal artesunate in severe malaria: flawed trial

    Premji Zulfiqarali G


    Full Text Available Abstract Background Immediate injectable treatment is essential for severe malaria. Otherwise, the afflicted risk lifelong impairment or death. In rural areas of Africa and Asia, appropriate care is often miles away. In 2009, Melba Gomes and her colleagues published the findings of a randomized, placebo-controlled trial of rectal artesunate for suspected severe malaria in such remote areas. Enrolling nearly 18,000 cases, the aim was to evaluate whether, as patients were in transit to a health facility, a pre-referral artesunate suppository blocked disease progression sufficiently to reduce these risks. The affirmative findings of this, the only trial on the issue thus far, have led the WHO to endorse rectal artesunate as a pre-referral treatment for severe malaria. In the light of its public health importance and because its scientific quality has not been assessed for a systematic review, our paper provides a detailed evaluation of the design, conduct, analysis, reporting, and practical features of this trial. Results We performed a checklist-based and an in-depth evaluation of the trial. The evaluation criteria were based on the CONSORT statement for reporting clinical trials, the clinical trial methodology literature, and practice in malaria research. Our main findings are: The inclusion and exclusion criteria and the sample size justification are not stated. Many clearly ineligible subjects were enrolled. The training of the recruiters does not appear to have been satisfactory. There was excessive between center heterogeneity in design and conduct. Outcome evaluation schedule was not defined, and in practice, became too wide. Large gaps in the collection of key data were evident. Primary endpoints were inconsistently utilized and reported; an overall analysis of the outcomes was not done; analyses of time to event data had major flaws; the stated intent-to-treat analysis excluded a third of the randomized subjects; the design

  3. The approach of ischemic colitis case followed by the lower gastrointesitnal bleeding



    Full Text Available Colonic vascular ischemia is commonly seen in the descending colon and causes malnutrition and is to be commensurate with the duration of clinical myocardial ischemia. History of cerebrovascular disease, hypertension, with coronary hearth disease, 68-year-old female patient was followed for about 2 weeks with the occasional massive gastrointestinal bleeding complaint. After ceasing oral intake, fluid and electrolyte replacement and a broad-spectrum antibiotic therapy was established. Abdomen bowel wall thickening of the colon in continuity in the CT results were observed with the open SMA SMV. Follow-up colonoscopy was performed from the dentate line at 5 cm starting hemorrhagic and ischemic segments was seen as an area of ​​about 40 cm long. After hemodynamic deterioration she was underwent emergency surgery because of abdominal sensitivity increase. Hartman procedure was performed. Postop pneumonia and pulmonary embolism were suspected. Candida was observed in urine infection. The sudden improving of the patient's postoperative bleeding from the rectal stump where the staple line was, has evolved on the 7th day. The sponges with the adrenaline stopped the bleeding and the hemodynamic support was stabilized with it. The minimal fluid in pelvis was also monitored by ultrasound . The colostomy was fine following the blood supply to the bowel. Later oral intake was started, the general condition of the patient was improved. But on the postoperative day 12 she had suddenly respiratory and cardiac arrest . Finally, the histopathological examination revealed that the ischemic necrosis and purulent some areas could be selected as a morphologic ischemic and necrotic (the intraoperative peritoneal reflection of the level of false membrane formation at the perforation focus off ischemic colitis. Approximately 20% of similar cases were followed with the clinical practice under medical treatment and surgical approach. [J Contemp Med 2017; 7(1.000: 74-76

  4. Red blood cell transfusion is associated with increased rebleeding in patients with nonvariceal upper gastrointestinal bleeding.

    Restellini, S; Kherad, O; Jairath, V; Martel, M; Barkun, A N


    There exists considerable practice variation and little evidence to guide red blood cell (RBC) transfusion in patients with nonvariceal upper gastrointestinal bleeding (NVUGIB). Studies in other critically ill cohorts suggest associations between transfusions and adverse patient outcomes. To characterise any possible clinically-relevant association between RBC transfusion following NVUGIB with rebleeding and mortality. Observational study utilising the Canadian Registry of patients with Upper Gastrointestinal Bleeding and Endoscopy (RUGBE). Multivariable logistic regression models were used to examine and quantify independent associations between RBC transfusion and clinical outcomes. Overall, 1677 patients were included (66.2 ± 16.8 years, 61.7% male, 2.5 ± 1.7 comorbid conditions, initial haemoglobin, 96.8 ± 27.2 g/L); 53.7% received RBC transfusions (2.9 ± 1.6 units of blood), 31.6% had haemodynamic instability, 5.1% fresh blood on rectal examination and 8.6% in the nasogastric tube aspirate. Endoscopic haemostasis was performed in 35.2%. Overall rebleeding (defined as continuous bleeding, rebleeding or surgery) and mortality rates were 17.9% and 5.4%, respectively. After adjusting for potential confounders, transfusion of RBC within 24 h of presentation was significantly and independently associated with an increased risk of rebleeding (OR: 1.0, 95% CI: 0.6-1.8), but not death (OR: 1.5, 95% CI: 0.94-2.23). This study suggests an association between RBC transfusion following NVUGIB and subsequent rebleeding, after appropriate and extensive adjustment for confounding. Prospective randomised trial evidence is needed to identify the most efficacious and cost-effective transfusional strategies in these patients. © 2012 Blackwell Publishing Ltd.

  7. Significance of thermoradiotherapy for rectal cancer

    Ike, Hideyuki; Fukano, Masahiko; Yamaguchi, Sigeki [Yokohama City Univ. (Japan). School of Medicine] [and others


    In patients with rectal cancer, results of 27 cases receiving thermoradiotherapy and of 68 cases, radiotherapy before operation were compared with those of 119 cases receiving expanded radical operation. Radiotherapy was done with 10 MV X-ray generated by linear-accelerator at 2.0 Gy x 5/week and 60 Gy in total. Hyperthermotherapy was performed with the capacitive heating method with 8 MHz radiofrequency (Thermotoron RF8) twice/week x 5. Every thermotherapy was done for 40 min at 42degC-43degC within 1 hr after the radiotherapy. Good results were observed in cases whose cancer was disappeared by either preoperative therapy. However, results in survival and recurrence rates were not always improved when compared with those receiving surgery alone. (K.H.)

  8. Pouch Techniques in Rectal Cancer Surgery

    Christoph A. Maurer


    Rectal cancer of the middle and distal third of the rectum are nowadays managed by low or ultra-low anterior resection with total mesorectal excision and coloanal anastomosis. Following straight coloanal anastomosis, patients often suffer from high stool frequency, urgency and, occasionally, fecal incontinence. To overcome these problems, several types of colonic reservoirs (pouches) have been proposed. The following article elucidates the indications and contraindications for the creation of a pouch. Furthermore, the paper gives a short overview of the different pouch designs that are widely accepted and currently in use, with special emphasis of the typical advantages, disadvantages and feasibility. Current guide-lines recommend to perform a colonic pouch since it provides functional benefits over straight coloanal anastomosis with no increase in postoperative complications.

  9. Radiotherapy and local control in rectal cancer.

    Valentini, V; Rosetto, M E; Fares, C; Mantini, G; Salvi, G; Turriziani, A


    Recurrence is a stage in the natural history of rectal cancer. Preoperative radiotherapy or postoperative radiochemotherapy lower the rate of recurrence, improving local control. From 1980 to 1997, at the "Divisione di Radioterapia" of the "Università Cattolica del S. Cuore" of Rome 380 patients with rectal cancer of early clinical stage T2-3, candidates for surgery for cure, underwent radiation therapy. 119 patients underwent postoperative radiotherapy (45-50 Gy); 45 patients underwent "sandwich" radiotherapy (45 Gy:27 Gy before and 28 Gy after surgery), of whom 7 were treated with preoperative radiotherapy alone; 145 patients underwent preoperative concomitant radiochemotherapy according to 3 different protocols, radiotherapy (38 Gy) combined with mitomycin C and 5-FU; radiotherapy (50.4 Gy) combined with cisplatin and 5-FU; radiotherapy (45 Gy) combined with 5-FU and folinic acid. 71 patients were treated with preoperative radiotherapy (38 Gy) combined with IORT (10 Gy). Median follow-up was 6 years. Overall local control was 85% at 3 years, 83% at 5 years, 81% at 10 years. The rate of local control at 5 years was: 76% for postoperative radiotherapy, 83% for "sandwich" radiotherapy, 84% for preoperative radiochemotherapy and 93% for preoperative radiotherapy combined with IORT. Local control was shown to be significantly better with preoperative treatment as compared to postoperative treatment (p = 0.02). The incidence of metastases was 35% in the patients with local recurrence and 16% in those with local control. The difference in survival was highly significant in patients with local control as compared to those with local recurrence: at 5 years 87% and 32% respectively. Patients with local control showed a lower incidence of metastasis and a better survival.

  10. Upper gastrointestinal bleeding: predictors of risk in a mixed patient group including variceal and nonvariceal haemorrhage.

    Lahiff, Conor; Shields, William; Cretu, Ion; Mahmud, Nasir; McKiernan, Susan; Norris, Suzanne; Silke, Bernard; Reynolds, John V; O'Toole, Dermot


    Effective management of upper gastrointestinal bleeding (UGIB) relies on the application of clinical risk scores. The validation of risk scores has to date focused mainly on nonvariceal UGIB groups. We aimed to evaluate our clinical and endoscopic management of UGIB, and to validate existing risk scores for a mixed patient population with a high percentage of variceal bleeds. Analysis included UGIB patients presenting consecutively to a tertiary referral university hospital. All patients had been admitted by our emergency department and had undergone upper gastrointestinal endoscopy. Clinical, biochemical and endoscopic data were recorded. Clinical and complete Rockall and Blatchford risk scores were calculated for all patients and statistical analysis was carried out by a multiple logistical regression model. A total of 21% of patients had variceal bleeds. There was considerable heterogeneity between groups with the variceal group having more comorbidities (P=0.003), lower haemoglobin (P=0.003) and lower systolic blood pressure (P=0.013) at presentation. This translated to higher risk scores (Pbleeding or mortality. However, no patient with a Blatchford score of 0 had an adverse clinical outcome. Postendoscopic Rockall score can be used as a predictor of outcome for mixed UGIB groups. Although Blatchford score did not predict outcome in our study, at a 0 level it does appear to be a safe triage tool for pre-endoscopic identification of patients with variceal bleeds, even where there is no known history of liver disease.

  11. Correlation of bleeding pattern with endometrial histopathologic results in perimenopausal women with abnormal uterine bleeding

    Zehra Yilmaz


    Full Text Available Background: Abnormal Uterine Bleeding (AUB is referred as bleeding outside of normal menstruation pattern and it is the most common gynecological problem for women of all ages. This study was evaluated the correlation of menstrual bleeding patterns and endometrial histopathological findings in perimenopausal women. Methods: This study was done on perimenopausal aged women presented with AUB for the last 6 months at a gynecology clinic of a tertiary medical center. Only the patients with isolated endometrial causes of AUB were selected for study. A total of 313 cases were included in the study. Abnormal bleeding patterns of the patients were recorded and endometrial sampling was performed to all women. AUB was classified as menorrhagia, metrorrhagia, menometrorrhagia, polymenorrhea, intermenstrual bleeding, and histopathological findings were classified as Proliferative Endometrium (PE, Secretory Endometrium (SE, Disordered Proliferative Pattern (DPP, Endometrial Polyp (EP, Chronic Endometritis (CE, Endometrial Hyperplasia (EH, and Endometrial Adenocarcinoma (CA. Results: The most common bleeding pattern was menorrhagia (45.0% and the most common histopathological finding was PE+SE (52.0% in our study. PE+SE and endometrial hyperplasia without atypia were found more common in menorrhagia group. The most histopathological findings were found PE+SE in menometrorrhagia and polymenorrhea group (P 0.05. Conclusions: We concluded that although menometrorrhagia and polymenorrhea were significantly more associated with PE+SE, intermenstrual bleeding was significantly more associated with EP and CE. It is noteworthy that endometrial hyperplasia without atypia is significantly higher in patients with menorrhagia which is the most common abnormal bleeding pattern in perimenopausal aged women.

  12. Initial Assessment and Resuscitation in Nonvariceal Upper Gastrointestinal Bleeding.

    Simon, Tracey G; Travis, Anne C; Saltzman, John R


    Acute nonvariceal upper gastrointestinal bleeding remains an important cause of hospital admission with an associated mortality of 2-14%. Initial patient evaluation includes rapid hemodynamic assessment, large-bore intravenous catheter insertion and volume resuscitation. A hemoglobin transfusion threshold of 7 g/dL is recommended, and packed red blood cell transfusion may be necessary to restore intravascular volume and improve tissue perfusion. Patients should be risk stratified into low- and high-risk categories, using validated prognostic scoring systems such as the Glasgow-Blatchford, AIMS65 or Rockall scores. Effective early management of acute, nonvariceal upper gastrointestinal hemorrhage is critical for improving patient outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

  14. Bleeding risk of intracranial vascular malformations; Das Risiko intrazerebraler Gefaessmissbildungen

    Wanke, I.; Panagiotopoulos, V.; Forsting, M. [Universitaetsklinikum Essen, Inst. fuer diagnostische und interventionelle Radiologie und Neuroradiologie (Germany)


    In general, intracranial vascular malformations are divided into pial AVM, dural AV fistula, cavernoma and capillary telangiectasias. Developmental venous anomalies are sometimes thought to be vascular malformations. In fact, they are just a variant of venous drainage. In general, pial AVMs have a high risk of intracerebral bleeding. In dural AV fistulas, the individual bleeding risk can be effectively estimated by analyzing the venous drainage. Cavernomas have a low bleeding risk and the bleeding is rarely life-threatening. DVAs do not have any bleeding risk but 30 % are associated with cavernomas. Capillary telangiectasias also have no bleeding risk. Therefore, a radiological finding of an intracranial vascular malformation should not automatically elicit the reaction ''time bomb in your head with a bleeding risk'' but should be subjected to an analysis of the bleeding risk for the individual patient.

  16. BLEEDING AND STARVING: fasting and delayed refeeding after upper gastrointestinal bleeding

    Jorge FONSECA


    Full Text Available Context Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. Objectives The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. Methods From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall score; endoscopic data, including severity of lesions and therapy; feeding related records of seven days: liquid diet prescription, first liquid intake, soft/solid diet prescription, first soft/solid intake. Results From 133 patients (84 men Rockall classification was possible in 126: 76 score ≥5, 50 score <5. One persistent bleeding, eight rebled, two underwent surgery, 13 died. Ulcer was the major bleeding cause, 63 patients underwent endoscopic therapy. There was 142/532 possible refeeding records, no record 37% patients. Only 16% were fed during the first day and half were only fed on third day or later. Rockall <5 patients started oral diet sooner than Rockall ≥5. Patients that underwent endoscopic therapy were refed earlier than those without endotherapy. Conclusions Most feeding records are missing. Data reveals delayed refeeding, especially in patients with low-risk lesions who should have been fed immediately. Nonvariceal upper gastrointestinal bleeding patients must be refed earlier, according to guidelines.

  19. Capsule endoscopy: Current status in obscure gastrointestinal bleeding

    R Gupta; Nageshwar Duvvuru Reddy


    Capsule endoscopy (CE) is a safe, non invasive diagnostic modality for the evaluation of small bowel lesions. Obscure gastrointestinal bleeding (OGIB) is one of the most important indications of capsule endoscopy.Capsule endoscopy has a very high diagnostic yield especially if the bleeding is ongoing. This technique appears to be superior to other techniques for the detection of suspected lesions and the source of bleeding. Capsule endoscopy has been shown to change the outcome in patients with obscure gastrointestinal (GI)bleed.

  1. Rectal Carcinoma with Heterotopic Bone: Report of a Case

    Yuichi Nagao


    Full Text Available Heterotopic bone is rarely present in malignant tumors of the gastrointestinal tract. We herein report a case of rectal adenocarcinoma with heterotopic bone. A 46-year-old Japanese male presented to our hospital with abdominal distension and constipation. Colonoscopic examination showed an ulcerated polypoid tumor of the rectum which nearly obstructed the rectal lumen. Abdominal computed tomography showed a tumor of the rectum with calcified deposits. Low anterior resection with lateral lymph node dissection was performed under the tentative diagnosis of rectal cancer. Histological examination of the resected specimen showed mucinous carcinoma of the rectum with heterotopic bone. One of the metastatic lymph nodes dissected also showed heterotopic bone. In the present report, we describe this rare tumor and briefly review the pertinent literature regarding rectal cancer with heterotopic bone.

    Wei, Hongbo; Master, Jiafeng Fang; Chen, Tufeng; Zheng, Zongheng; Wei, Bo; Huang, Yong; Huang, Jianglong; Master, Haozhong Xu


    Laparoscopy-assisted surgery for either rectal or gastric cancer has been increasingly performed. However, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is rarely reported in the literature. In our study, 3 cases of patients who received simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer were recorded. The results showed that all 3 patients recovered well, with only 253 minutes of mean operation time, 57 mL of intraoperative blood loss, 5 cm of assisted operation incision, 4 days to resume oral intake, 12 days' postoperative hospital stay, and no complication or mortality. No recurrence or metastasis was found within the follow-up period of 22 months. When performed by surgeons with plentiful experience in laparoscopic technology, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is safe and feasible, with the benefits of minimal trauma, fast recovery, and better cosmetic results, compared with open surgery.

    An interesting case of rectal amebic abscess is presented. Ultrasound and CT images provided the diagnosis of a cystic intramural mass at the rectal wall of a young man, who complained of pelvic pain, constipation, and fever. His clinical history of amebiasis and the finding of trophozoids and cysts at the stool swap confirmed the diagnosis. Intravenous metronidazole therapy cured the disease and led to total disappearance of the mass, and clinical well-being. (orig.) With 4 figs., 6 refs.

  10. Salvage Total Pelvic Exenteration with Bilateral V-Y Advancement Flap Reconstruction for Locally Recurrent Rectal Cancer

    Jo Tashiro


    Full Text Available Total pelvic exenteration for locally recurrent rectal cancer typically requires extensive excision of the pelvic floor with perineal skin. Due to the extensiveness of the procedure and its non-curative nature, it is controversial as purely palliative therapy. A 66-year-old male patient who had undergone abdominoperineal resection at another hospital 8 years prior was admitted to our hospital. During radiation and chemotherapy for 2 years, he complained of perineal pain, discharge, cacosmia and bleeding from a recurrent tumor. The 10 × 8 cm recurrent tumor was exposed on the perineum and the patient suffered from serious discomfort in his daily life during walking or sitting. We performed total pelvic exenteration with partial sacrectomy, after which the large perineal defect was reconstructed with a bilateral V-Y gluteus maximus advancement flap in approximately 120 min. The patient's postoperative course was satisfactory and his quality of life markedly improved.

  11. Laparoscopic rectal cancer surgery: Where do we stand?

    Mukta K Krane; Alessandro Fichera


    Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer.In contrast,laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm.While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach,whether the same oncologic clearance,specifically an adequate TME can be obtained is of concern.The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes.The data from 8 RCTs,3 metaanalyses,and 2 Cochrane Database of Systematic Reviews was reviewed.Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss,earlier retum of bowel function,and shorter hospital length of stay.Concerns that laparoscopic rectal cancer surgery compromises shortterm oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature.Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

    Bruno Amaral Medeiros


    Full Text Available OBJECTIVE: To evaluate results obtained in 48 cases of perineal rectosigmoidectomy in patients with rectal procidentia. METHODS: 48 medical records of patients undergoing PRS were analyzed, retrospectively. RESULTS: Before surgery, 44 patients (77.1% reported complaints of anal mass and rectal bleeding was reported 13 times (22.8%. The period of hospitalization was 3.91 days (2 to 12 days. Women were the majority (85.4%. The mean age was 73.8 years (49 to 101 years. The average time of surgery was 72 minutes (40 to 90 minutes.

  13. Endoscopy for nonvariceal upper gastrointestinal bleeding.

    Kim, Ki Bae; Yoon, Soon Man; Youn, Sei Jin


    Endoscopy for acute nonvariceal upper gastrointestinal bleeding plays an important role in primary diagnosis and management, particularly with respect to identification of high-risk stigmata lesions and to providing endoscopic hemostasis to reduce the risk of rebleeding and mortality. Early endoscopy, defined as endoscopy within the first 24 hours after presentation, improves patient outcome and reduces the length of hospitalization when compared with delayed endoscopy. Various endoscopic hemostatic methods are available, including injection therapy, mechanical therapy, and thermal coagulation. Either single treatment with mechanical or thermal therapy or a treatment that combines more than one type of therapy are effective and safe for peptic ulcer bleeding. Newly developed methods, such as Hemospray powder and over-the-scope clips, may provide additional options. Appropriate decisions and specific treatment are needed depending upon the conditions.

  14. Duodenal Bleeding from Metastatic Renal Cell Carcinoma

    Rustagi, Tarun; Rangasamy, Priya; Versland, Mark


    Massive upper gastrointestinal bleeding due to malignancy is relatively uncommon and the duodenum is the least frequently involved site. Duodenal metastasis is rare in renal cell carcinoma (RCC) and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosal mass was noted in the duodenum, biopsies of which revealed metastatic RCC. In conclusion, metastasis from RCC should be considered in nephrectomized patients presenting with gastrointestinal symptoms and a complete evaluation, especially endoscopic examination followed by biopsy, is suggested.

  16. Vitamin K deficiency bleeding: a case study.

    Woods, Christopher W; Woods, Amanda G; Cederholm, Carmen K


    Vitamin K deficiency bleeding (VKDB), formerly known as hemorrhagic disease of the newborn (HDN), is a bleeding disorder in neonates that is caused by inadequate serum levels of vitamin K. Vitamin K is a nutrient essential for adequate function of the coagulation cascade. Certain internal and external factors place newborn infants at higher risk for VKDB. Therefore, vitamin K prophylaxis has become the standard of care for newborns. Although the American Academy of Pediatrics recommends the administration of vitamin K to newborns, some parents are choosing to withhold vitamin K administration at birth. This case study describes an infant who developed VKDB in the absence of vitamin K prophylaxis. Although parents ultimately have the right to choose whether or not to administer vitamin K, as healthcare professionals, it is important to provide education regarding the potential complications of withholding vitamin K and the signs of VKDB if vitamin K prophylaxis at birth is withheld.

  1. Secondary prophylaxis for esophageal variceal bleeding.

    Albillos, Agustín; Tejedor, Marta


    Combination therapy with beta-blockers and endoscopic band ligation (EBL) is the standard prophylaxis of esophageal variceal rebleeding in cirrhosis. Beta-blockers are the backbone of combination therapy, since their benefit extend to other complications of portal hypertension. EBL carries the risk of post-banding ulcer bleeding, which explains why overall rebleeding is reduced when beta-blockers are added to EBL, and not when EBL is added to beta-blockers. TIPS is the rescue treatment, but it could be considered as first choice in patients that first bleed while on beta-blockers, those with contraindications to beta-blockers or with refractory ascites, and those with fundal varices.

  2. The clinicopathological study of postmenopausal bleeding

    Rita D.


    Results: In patients with post-menopausal bleeding, atrophic endometrium was seen in 31%, proliferative endometrium in 13%, isthmic endometrium in 5%, polyp in 5%, simple hyperplasia without atypia in 35%, simple hyperplasia with atypia in 3%, complex hyperplasia without atypia in 1%, complex hyperplasia with atypia in 1% and endometrial carcinoma in 6% of the patients with PMB. Benign conditions were seen in 94% and malignancy was seen in 6% cases. Conclusions: The most common causes for postmenopausal bleeding were endometrial hyperplasia (40%, atrophic endometrium (31%, isthmic endometrium (5%, polyp (5%, proliferative endometrium (13% and endometrial carcinoma (6%. A definitive diagnosis of PMB can be made by histological evaluation. Obesity, hypertension, diabetes mellitus and age since menopause are the risk factors for PMB.

  4. Interventional management of lower gastrointestinal bleeding

    Weldon, Derik T.; Burke, Stephen J.; Sun, Shiliang; Mimura, Hidefumi; Golzarian, Jafar [University of Iowa Hospitals and Clinics, Department of Radiology, Iowa, IA (United States)


    Lower gastrointestinal bleeding (LGIB) arises from a number of sources and is a significant cause of hospitalization and mortality in elderly patients. Whereas most episodes of acute LGIB resolve spontaneously with conservative management, an important subset of patients requires further diagnostic workup and therapeutic intervention. Endovascular techniques such as microcatheter embolization are now recognized as safe, effective methods for controlling LGIB that is refractory to endoscopic intervention. In addition, multidetector CT has shown the ability to identify areas of active bleeding in a non-invasive fashion, enabling more focused intervention. Given the relative strengths and weaknesses of various diagnostic and treatment modalities, a close working relationship between interventional radiologists, gastroenterologists and diagnostic radiologists is necessary for the optimal management of LGIB patients.

  5. Risk factors for major bleeding in the SEATTLE II trial.

    Sadiq, Immad; Goldhaber, Samuel Z; Liu, Ping-Yu; Piazza, Gregory


    Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis minimizes the risk of intracranial bleeding compared with systemic full-dose fibrinolytic therapy for pulmonary embolism (PE). However, major bleeding is nevertheless a potential complication. We analyzed the 150-patient SEATTLE II trial of submassive and massive PE patients to describe those who suffered major bleeding events following ultrasound-facilitated, catheter-directed, low-dose fibrinolysis and to identify risk factors for bleeding. Major bleeding was defined as GUSTO severe/life-threatening or moderate bleeds within 72 hours of initiation of the procedure. Of the 15 patients with major bleeding, four (26.6%) developed access site-related bleeding. Multiple venous access attempts were more frequent in the major bleeding group (27.6% vs 3.6%; p<0.001). All patients with major bleeding had femoral vein access for device delivery. Patients who developed major bleeding had a longer intensive care stay (6.8 days vs 4.7 days; p=0.004) and longer hospital stay (12.9 days vs 8.4 days; p=0.004). The frequency of inferior vena cava filter placement was 40% in patients with major bleeding compared with 13% in those without major bleeding ( p=0.02). Massive PE (adjusted odds ratio 3.6; 95% confidence interval 1.01-12.9; p=0.049) and multiple venous access attempts (adjusted odds ratio 10.09; 95% confidence interval 1.98-51.46; p=0.005) were independently associated with an increased risk of major bleeding. In conclusion, strategies for improving venous access should be implemented to reduce the risk of major bleeding associated with ultrasound-facilitated, catheter-directed, low-dose fibrinolysis.

  6. The role of endoscopy in pediatric gastrointestinal bleeding

    Franke, Markus; Geiß, Andrea; Greiner, Peter; Wellner, Ulrich; Richter-Schrag, Hans-Jürgen; Bausch, Dirk; Fischer, Andreas


    Background and study aims: Gastrointestinal bleeding in children and adolescents accounts for up to 20 % of referrals to gastroenterologists. Detailed management guidelines exist for gastrointestinal bleeding in adults, but they do not encompass children and adolescents. The aim of this study was to assess gastrointestinal bleeding in pediatric patients and to determine an investigative management algorithm accounting for the specifics of children and adolescents. Patients and methods: Pediatric patients with gastrointestinal bleeding admitted to our endoscopy unit from 2001 to 2009 (n = 154) were identified. Retrospective statistical and neural network analysis was used to assess outcome and to determine an investigative management algorithm. Results: The source of bleeding could be identified in 81 % (n = 124/154). Gastrointestinal bleeding was predominantly lower gastrointestinal bleeding (66 %, n = 101); upper gastrointestinal bleeding was much less common (14 %, n = 21). Hematochezia was observed in 94 % of the patients with lower gastrointestinal bleeding (n = 95 of 101). Hematemesis (67 %, n = 14 of 21) and melena (48 %, n = 10 of 21) were associated with upper gastrointestinal bleeding. The sensitivity and specificity of a neural network to predict lower gastrointestinal bleeding were 98 % and 63.6 %, respectively and to predict upper gastrointestinal bleeding were 75 % and 96 % respectively. The sensitivity and specifity of hematochezia alone to predict lower gastrointestinal bleeding were 94.2 % and 85.7 %, respectively. The sensitivity and specificity for hematemesis and melena to predict upper gastrointestinal bleeding were 82.6 % and 94 %, respectively. We then developed an investigative management algorithm based on the presence of hematochezia and hematemesis or melena. Conclusions: Hematochezia should prompt colonoscopy and hematemesis or melena should prompt esophagogastroduodenoscopy. If no

  9. Neurenteric Cyst Presenting with Bleeding Per Rectum.

    Yadav, Taruna; Parmar, Padam; Rattan, Kamal Nain


    Neurenteric cyst in the thoracic cavity may produce a myriad of clinical features. We report a 7-month-old girl who presented with significant bleeding per rectum. On imaging, a mediastinal cystic structure with air-fluid levels was evident with cervico-thoracic vertebral anomalies. The cyst was excised and histopathology showed intestinal mucosal lining with heterotopic pancreatic tissue confirming the diagnosis of neurenteric cyst.

  10. Bleeding gums: Duloxetine may be the cause

    Balhara YPS


    Full Text Available Duloxetine is a newly introduced drug. It is being prescribed for the management of diabetic neuropathic pain and major depressive disorder. The most frequently observed adverse events with duloxetine are nausea, dry mouth and somnolence, constipation, diarrhea, decreased appetite, weight loss, feeling of fatigue, dizziness, somnolence, hypohidrosis, decreased libido and erectile dysfunction. One of the patients being prescribed the drug developed bleeding gums on being started with the drug which resolved on stopping it. We hereby report this case.

  11. [Bleeding non-epithelial gastrointestinal neoplasms].

    Zak, V I; Galtsev, A P


    Inefficiency of x-ray and endoscopic examinations of a bleeding hollow organ of the gastrointestinal tract may be explained by the effection of its wall with nonepithelial tumor (lipoma, neurinoma, leiomyoma). In some cases only laparotomy and examination of the abdominal cavity succeed in localization of the tumor. Intraoperative cytodiagnosis of nonepithelial benign tumors is a method conducive to sparing surgery (partial resection, dissection).

  12. Endoscopic hemoclip treatment for bleeding peptic ulcer

    Yung Chih Lai; Sien Sing Yang; Chi Hwa Wu; Tzen Kwan Chen


    AIM To evaluate the efficacy of endoscopic hemoclip in the treatment of bleeding peptic ulcer.METHODS Totally, 40 patients with F1a and F1b hemorrhagic activity of peptic ulcers were enrolled in this uncontrolled prospective study for endoscopic hemoclip treatment. We used a newly developed rotatable clip-device for the application of hemoclip (MD850) to stop bleeding. Endoscopy was repeated if there was any sign or suspicion of rebleeding, and reclipping was performed if necessary and feasible.RESULTS Initial hemostatic rate by clipping was 95%, and rebleeding rate was only 8%.Ultimate hemostatic rates were 87%, 96%, and 93% in the F1a and F1b subgroups, and total cases, respectively. In patients with shock on admission, hemoclipping achieved ultimate hemostasis of 71% and 83% in F1a and F1b subgroups, respectively. Hemostasis reached 100% in patients without shock regardless of hemorrhagic activity being F1a or F1b. The average number of clips used per case was 3.0 (range 2- 5). Spurting bleeders required more clips on average than did oozing bleeders (3.4 versus 2.8 ). We observed no obvious complications, no tissue injury, or impairment of ulcer healing related to hemoclipping.CONCLUSION Endoscopic hemoclip placement is an effective and safe method. With the improvement of the clip and application device,the procedure has become easier and much more efficient. Endoscopic hemoclipping deserves further study in the treatment of bleeding peptic ulcers.

  13. The evaluation of rectal mucosal punch biopsy in the diagnosis of Hirschsprung's disease: a 30-year experience of 954 patients.

    Yoshimaru, Koichiro; Kinoshita, Yoshiaki; Yanagi, Yusuke; Obata, Satoshi; Jimbo, Takahiro; Iwanaka, Tsuyoshi; Takahashi, Yoshiaki; Esumi, Genshiro; Miyata, Junko A; Matsuura, Toshiharu; Izaki, Tomoko; Taguchi, Tomoaki


    For 30 years, we have consecutively performed rectal mucosal punch biopsy to diagnose Hirschsprung's disease. The aim of this study was to evaluate the safety of our technique. Patients with suspected Hirschsprung's disease who underwent punch biopsy, including our original "K-PUNCH" method using an S-moid forceps and non-specific blood-collecting tube at our department and branch hospital between April 1986 and March 2016 were included in the present study. Our punch biopsy technique is characterized by excellent visibility and a direct grasping sensation. The backgrounds and complications of the patients were retrospectively investigated. During this period, 954 patients (median age 4 months; range 1 day-73 years) underwent punch biopsy. Although there were no cases of severe complications (i.e., rectal perforation, infection or full-thickness biopsy), one (0.1%) of the 954 cases in the early period showed liver dysfunction and required transfusion due to bleeding. In addition, inappropriate specimens were obtained in 37 patients (3.9%). Punch biopsy including the "K-PUNCH" method is considered safe and feasible and is associated with a low rate of complications and inappropriate specimen harvesting among patients of all ages. Comorbidities, including the potential for hemorrhage, should always be considered.

  14. Sphincter sparing resection of a large obstructive distal rectal gastrointestinal stromal tumour after neoadjuvant therapy with imatinib (Glivec).

    Kramp, Kelvin Harvey; Omer, Mohab Galal; Schoffski, Patrick; d'Hoore, Andre


    Gastrointestinal stromal tumours (GISTs) are generally rare but are known to be the most common mesenchymal tumours of the gastrointestinal tract. We present a case of a patient who presented with persistent obstructive gastrointestinal and urological symptoms, a sense of incomplete evacuation and bleeding per rectum. A colonoscopy was performed and a biopsy was taken of a submucosal mass in the distal rectum that revealed a GIST with positive KIT immunostaining. A positron emission tomography (PET)/CT scan showed a large metabolically active distal rectal tumour of 8 cm with macroscopic invasion of surrounding structures. Neoadjuvant therapy with receptor tyrosine kinase inhibitor imatinib (400 mg orally daily) was initiated and an excellent partial response consisting of a significant decrease in the size of the tumour with complete metabolic resolution was observed within 3 months. Six months after initiation of the neoadjuvant therapy a rectum resection with manual side-to-end coloanal anastomosis was performed. Pathology showed a GIST of 5 cm located 0.1 cm from the distal section plane. Our case shows that in patients with a large invasive distal rectal GIST, neoadjuvant imatinib therapy can facilitate anal sphincter sparing surgery.

  15. Corpus luteum hemorrhage in women with bleeding disorders.

    Hoffman, Ron; Brenner, Benjamin


    Bleeding into the corpus luteum following ovulation rarely has clinical significance in healthy women, but may lead to life-threatening hemorrhage in women with congenital or acquired bleeding disorders. Women who are at an increased risk for corpus luteum hemorrhage (CLH) can be divided in two categories; first, those taking anticoagulants because of a thrombotic disorder; and second, women with congenital bleeding disorders. The management and prevention of CLH is still unsettled and the literature dealing with this problem is based on case reports only. This review focuses on the pathophysiology, clinical presentation, diagnosis and treatment options of an acute bleeding event and prevention modalities of CLH in women with bleeding disorders.

  16. The usefulness of MDCT in acute intestinal bleeding

    Kim, Kum Rae; Park, Won Kyu; Kim, Jae Woon; Chang, Jay Chun; Jang, Han Won [College of Medicine, Yeungnam University, Daegu (Korea, Republic of)


    We wanted to evaluate the usefulness of MDCT for localizing a bleeding site and for helping make a decision on further management for acute intestinal bleeding. We conducted a retrospective review of 17 consecutive patients who presented with acute intestinal bleeding and who also underwent MDCT before angiography or surgery. The sensitivity of MDCT for detecting acute intestinal bleeding was assessed and compared with that of conventional angiography. The sensitivity of MDCT for the detection of acute intestinal bleeding was 77% (13 or 17), whereas that of angiography was 46% (6 or 13). All the bleeding points that were subsequently detected on angiography were visualized on MDCT. In three cases, the bleeding focus was detected on MDCT and not on angiography. In four cases, both MDCT and angiography did not detect the bleeding focus; for one of these cases, CT during SMA angiography was performed and this detected the active bleeding site. In patients with acute intestinal bleeding, MDCT is a useful image modality to detect the bleeding site and to help decide on further management before performing angiography or surgery. When tumorous lesions are detected, invasive angiography can be omitted.

  17. Use of self-expanding covered stent and negative pressure wound therapy to manage late rectal perforation after injury from an improvised explosive device: a case report.

    Ozer, M Tahir; Coskun, Ali K; Sinan, Huseyin; Saydam, Mehmet; Akay, Emin O; Peker, Subutay; Ogunc, Gokhan; Demirbas, Sezai; Peker, Yusuf


    Blast injuries, caused by explosions accompanied by high-pressure waves, produce tissue damage in the acute period, followed in the later period by circulatory disorders due to vascular endothelial damage and related tissue necrosis. Blunt rectal perforation is rare and difficult to diagnose. In the acute period following blast pelvic injuries, the main objectives are to stop bleeding, minimise contamination and preserve the patient's life. The patient in this report had major vascular injuries, severe pelvic injury and, in the later period, rectal perforation because of vascular endothelial damage caused by the blast effect. Our aim was to treat the patient conservatively because of his poor general condition. We placed a self-expanding covered stent (SECS) into the rectum and then applied negative pressure wound therapy (NPWT; V.A.C.® Therapy, KCI) to the pelvic region and perirectal area. At the end of the treatment, the rectal perforation was closed, and the patient was discharged with healing. In this article, we discuss the novel use of an SECS with NPWT and review related literature.

  18. Scintigraphic localisation of colonic bleeding; Scintigrafisk lokalisasjon av colonbloedning

    Aspevik, Ranveig K.; Miskowiak, Jerzy; I Bud, Margreta


    Background. Endoscopy and occasionally X-ray studies are used to discover the focus of a gastrointestinal bleeding. Material and methods. We describe a case of severe gastrointestinal bleeding where these methods failed. Scintigraphy after labelling of erythrocytes with 99m technetium was performed in a continuos manner for 60 minutes. Scintigrams were also taken three, ten and 23 hours after the injection. Results. No bleeding was revealed after 60 minutes but two hours later a slight radioactivity was encountered in the right part of the abdomen and the later images localised the bleeding in the right colon. The bleeding ceased after right-sided hemicolectomy. Interpretation. Scintigraphy is of value in localisation of gastrointestinal bleeding and should be performed in a continuos manner until the bleeding focus is localised. Secretion of unbound technetium through the mucosa of the stomach and its presence in the urinary tract should be taken in account.

  19. The discriminant power of bleeding history for the diagnosis of type 1 von Willebrand disease: an international, multicenter study.

    Rodeghiero, F; Castaman, G; Tosetto, A; Batlle, J; Baudo, F; Cappelletti, A; Casana, P; De Bosch, N; Eikenboom, J C J; Federici, A B; Lethagen, S; Linari, S; Srivastava, A


    The aim of this study was the validation of the criteria defining a significant mucocutaneous-bleeding history in type 1 von Willebrand disease (VWD). To avoid selection bias, 42 obligatory carriers (OC) of type 1 VWD were identified from a panel of 42 families with type 1 VWD enrolled by 10 expert centers. OC were identified by the presence of an offspring and another first degree relative with type 1 VWD (affected subjects, AFF). A standardized questionnaire was administered to evaluate hemorrhagic symptoms at the time of first examination, using a bleeding score ranging from 0 (no symptom) to 3 (hospitalization, replacement therapy, blood transfusion). Sensitivity, specificity, diagnostic likelihood ratios, positive and negative predictive values for the diagnosis of type 1 VWD were calculated from the data collected in OC and in 215 controls. Having at least three hemorrhagic symptoms or a bleeding score of 3 in males and 5 in females was very specific (98.6%) for the bleeding history of type 1 VWD, although less sensitive (69.1%). None of the misclassified OC had life-threatening bleeding episodes after diagnosis. We suggest that the use of a standardized questionnaire and bleeding score may be useful for the identification of subjects requiring laboratory evaluation for VWD.

  20. Cruciferous vegetables and colo-rectal cancer.

    Lynn, Anthony; Collins, Andrew; Fuller, Zoë; Hillman, Kevin; Ratcliffe, Brian


    Cruciferous vegetables have been studied extensively for their chemoprotective effects. Although they contain many bioactive compounds, the anti-carcinogenic actions of cruciferous vegetables are commonly attributed to their content of glucosinolates. Glucosinolates are relatively biologically inert but can be hydrolysed to a range of bioactive compounds such as isothiocyanates (ITC) and indoles by the plant-based enzyme myrosinase, or less efficiently by the colonic microflora. A number of mechanisms whereby ITC and indoles may protect against colo-rectal cancer have been identified. In experimental animals cruciferous vegetables have been shown to inhibit chemically-induced colon cancer. However, the results of recent epidemiological cohort studies have been inconsistent and this disparity may reflect a lack of sensitivity of such studies. Possible explanations for the failure of epidemiological studies to detect an effect include: assessment of cruciferous vegetable intake by methods that are subject to large measurement errors; the interaction between diet and genotype has not been considered: the effect that post-harvest treatments may have on biological effects of cruciferous vegetables has not been taken into account.

  1. Digital rectal examination in the evaluation of rectovaginal septal defects.

    Rachaneni, Suneetha; Atan, Ixora Kamisan; Shek, Ka Lai; Dietz, Hans Peter


    The objective was to evaluate the diagnostic potential of digital rectal examination in the identification of a true rectocele. This is a retrospective observational study utilising 187 archived data sets of women presenting with lower urinary tract symptoms and/or pelvic organ prolapse between August 2012 and November 2013. Evaluation included a standardised interview, ICS-POPQ, rectal examination and 4D translabial ultrasound. The main outcome measure was the diagnosis of rectocele by digital rectal palpation on Valsalva manoeuvre. This diagnosis correlated with the sonographic diagnosis of rectocele to determine agreement between digital examination and ultrasound findings. Complete data sets were available for 180 participants. On imaging, the mean position of the rectal ampulla was 11.07 (-36.3 to 44.3) mm below the symphysis pubis; 42.8% (77) had a rectocele of a depth of ≥10 mm. On palpation, a rectocele was detected in 60 women (33%). Agreement between palpation and imaging was observed in 77%; the kappa was 0.52 (CI 0.39-0.65). On receiver operator characteristic analysis, the area under the curve was 0.854 for the relationship between rectocele pocket depth and the detection of rectocele on palpation. Moderate agreement was found between digital rectal examination for rectocele and translabial ultrasound findings of a "true rectocele". Digital rectal examination may be used to identify these defects in clinical practice. Extending the clinical examination of prolapse to include rectal examination to palpate defects in the rectovaginal septum may reduce the need for defecatory proctograms for the assessment of obstructive defecation and may help triage patients in the management of posterior compartment prolapse.

    While there are many reported advantages to laparoscopic surgery compared to open surgery, the impact of a laparoscopic approach on postoperative morbidity in obese patients undergoing rectal surgery has not been studied. Our goal was to determine whether obese patients undergoing laparoscopic rectal surgery experienced the same benefits as non-obese patients. We identified patients undergoing rectal resections using the National Surgical Quality Improvement Project Participant Use Data File. We performed multivariable analyses to determine the independent association between laparoscopy and postoperative complications. A total of 26,437 patients underwent rectal resection. The mean age was 58.5 years, 32.6 % were obese, and 47.2 % had cancer. Laparoscopic procedures were slightly less common in obese patients compared to non-obese patients (36.0 vs. 38.2 %, p = 0.0006). In unadjusted analyses, complications were lower with the laparoscopic approach in both obese (18.9 vs. 32.4 %, p obese (15.6 vs. 25.3 %, p obesity worsened. The likelihood of experiencing a postoperative complication increased by 25, 45, and 75 % for obese class I, obese class II, and obese class III patients, respectively. A laparoscopic approach was associated with a 40 % decreased odds of a postoperative complication for all patients (OR 0.60, 95 % CI 0.56-0.64). Laparoscopic rectal surgery is associated with fewer complications when compared to open rectal surgery in both obese and non-obese patients. Obesity was an independent risk factor for postoperative complications. In appropriately selected patients, rectal surgery outcomes may be improved with a minimally invasive approach.

  3. Predicting the risk of bleeding during dual antiplatelet therapy after acute coronary syndromes.

    Alfredsson, Joakim; Neely, Benjamin; Neely, Megan L; Bhatt, Deepak L; Goodman, Shaun G; Tricoci, Pierluigi; Mahaffey, Kenneth W; Cornel, Jan H; White, Harvey D; Fox, Keith Aa; Prabhakaran, Dorairaj; Winters, Kenneth J; Armstrong, Paul W; Ohman, E Magnus; Roe, Matthew T


    Dual antiplatelet therapy (DAPT) with aspirin + a P2Y12 inhibitor is recommended for at least 12 months for patients with acute coronary syndrome (ACS), with shorter durations considered for patients with increased bleeding risk. However, there are no decision support tools available to predict an individual patient's bleeding risk during DAPT treatment in the post-ACS setting. To develop a longitudinal bleeding risk prediction model, we analy sed 9240 patients with unstable angina/non-ST segment elevation myocardial infarction (NSTEMI) from the Targeted Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage Acute Coronary Syndromes (TRILOGY ACS) trial, who were managed without revasculari sation and treated with DAPT for a median of 14.8 months. We identified 10 significant baseline predictors of non-coronary artery bypass grafting (CABG)-related Global Use of Strategies to Open Occluded Arteries (GUSTO) severe/life-threatening/moderate bleeding: age, sex, weight, NSTEMI (vs unstable angina), angiography performed before randomi sation, prior peptic ulcer disease, creatinine, systolic blood pressure, haemoglobin and treatment with beta-blocker. The five significant baseline predictors of Thrombolysis In Myocardial Infarction (TIMI) major or minor bleeding included age, sex, angiography performed before randomi sation, creatinine and haemoglobin. The models showed good predictive accuracy with Therneau's C-indices: 0.78 (SE = 0.024) for the GUSTO model and 0.67 (SE = 0.023) for the TIMI model. Internal validation with bootstrapping gave similar C-indices of 0.77 and 0.65, respectively. External validation demonstrated an attenuated C-index for the GUSTO model (0.69) but not the TIMI model (0.68). Longitudinal bleeding risks during treatment with DAPT in patients with ACS can be reliably predicted using selected baseline characteristics. The TRILOGY ACS bleeding models can inform risk -benefit considerations regarding the duration of DAPT following

  4. Initial assessment and management of patients with nonvariceal upper gastrointestinal bleeding.

    Bethea, Emily D; Travis, Anne C; Saltzman, John R


    Upper gastrointestinal bleeding (UGIB) is a substantial clinical and economic burden, with an estimated mortality rate between 3% and 15%. The initial management starts with hemodynamic assessment and resuscitation. Blood transfusions may be needed in patients with low hemoglobin levels or massive bleeding, and patients who are anticoagulated may require administration of fresh frozen plasma. Patients with significant bleeding should be started on a proton-pump inhibitor infusion, and if there is concern for variceal bleeding, an octreotide infusion. Patients with UGIB should be stratified into low-risk and high-risk categories using validated risk scores. The use of these risk scores can aid in separating low-risk patients who are suitable for outpatient management or early discharge following endoscopy from patients who are at increased risk for needing endoscopic intervention, rebleeding, and death. Upper endoscopy after adequate resuscitation is required for most patients and should be performed within 24 hours of presentation. Key to improving outcomes is appropriate initial management of patients presenting with UGIB.

  5. Nonvariceal upper gastrointestinal tract bleeding - risk factors and the value of emergency endoscopy.

    Wierzchowski, Pawel; Dabrowiecki, Stanislaw; Szczesny, Wojciech; Szmytkowski, Jakub


    Upper gastrointestinal tract bleeding (UGIB) remains a valid issue of modern medicine. The mortality and recurrence rates remain high and have not decreased as expected over the past decades. to assess the treatment outcomes of nonvariceal UGIB depending on the timing of endoscopy (urgent vs. elective) and to perform an analysis of risk factors for death in patients with nonvariceal UGIB. Comparative evaluation of treatment outcomes in two groups of patients. Group A consisted of patients undergoing elective endoscopy (n = 187). Group B consisted of patients undergoing emergency endoscopy (n = 295). Moreover, the influence of selected factors on the risk of death and bleeding recurrence was analyzed in the combined population of the two groups. This was done by constructing a logistic regression model and testing dependence hypotheses. In group A the mortality rate was 9.1%, and the recurrence rate was 18.2%. In group B the values were 6.8% and 12.2%, respectively. No statistically significant difference was found (p = NS). In group B the number of surgical interventions, blood transfusions and intensive care admissions was significantly lower (p bleeding from a malignant lesion, recurrent bleeding and the need for surgery (p < 0.05). The use of emergency endoscopy improves the treatment outcomes in patients with UGIB, although no statistically significant decrease in the mortality and recurrence rates could be observed.

    Purpose: Existing studies that examine the effect of neoadjuvant chemoradiation (CRT) for locally advanced rectal cancer on patient quality of life (QOL) are limited. Our goals were to prospectively explore acute changes in patient-reported QOL endpoints during and after treatment and to establish a distribution of scores that could be used for comparison as new treatment modalities emerge. Methods and Materials: Fifty patients with locally advanced rectal cancer were prospectively enrolled at 2 institutions. Validated cancer-specific European Organization for Research and Treatment of Cancer (EORTC QLQ-CR30) and colorectal cancer-specific (EORTC QLQ-CR38 and EORTC QLQ-CR 29) QOL questionnaires were administered to patients 1 month before they began CRT, at week 4 of CRT, and 1 month after they had finished CRT. The questionnaires included multiple symptom scales, functional domains, and a composite global QOL score. Additionally, a toxicity scale was completed by providers 1 month before the beginning of CRT, weekly during treatment, and 1 month after the end of CRT. Results: Global QOL showed a statistically significant and borderline clinically significant decrease during CRT (-9.50, P=.0024) but returned to baseline 1 month after the end of treatment (-0.33, P=.9205). Symptoms during treatment were mostly gastrointestinal (nausea/vomiting +9.94, P<.0001; and diarrhea +16.67, P=.0022), urinary (dysuria +13.33, P<.0001; and frequency +11.82, P=.0006) or fatigue (+16.22, P<.0001). These symptoms returned to baseline after therapy. However, sexual enjoyment (P=.0236) and sexual function (P=.0047) remained persistently diminished after therapy. Conclusions: Rectal cancer patients undergoing neoadjuvant CRT may experience a reduction in global QOL along with significant gastrointestinal and genitourinary symptoms during treatment. Moreover, provider-rated toxicity scales may not fully capture this decrease in patient-reported QOL. Although most symptoms are transient

  7. Integrating chromosomal aberrations and gene expression profiles to dissect rectal tumorigenesis

    Eilers Paul HC


    Full Text Available Abstract Background Accurate staging of rectal tumors is essential for making the correct treatment choice. In a previous study, we found that loss of 17p, 18q and gain of 8q, 13q and 20q could distinguish adenoma from carcinoma tissue and that gain of 1q was related to lymph node metastasis. In order to find markers for tumor staging, we searched for candidate genes on these specific chromosomes. Methods We performed gene expression microarray analysis on 79 rectal tumors and integrated these data with genomic data from the same sample series. We performed supervised analysis to find candidate genes on affected chromosomes and validated the results with qRT-PCR and immunohistochemistry. Results Integration of gene expression and chromosomal instability data revealed similarity between these two data types. Supervised analysis identified up-regulation of EFNA1 in cases with 1q gain, and EFNA1 expression was correlated with the expression of a target gene (VEGF. The BOP1 gene, involved in ribosome biogenesis and related to chromosomal instability, was over-expressed in cases with 8q gain. SMAD2 was the most down-regulated gene on 18q, and on 20q, STMN3 and TGIF2 were highly up-regulated. Immunohistochemistry for SMAD4 correlated with SMAD2 gene expression and 18q loss. Conclusion On basis of integrative analysis this study identified one well known CRC gene (SMAD2 and several other genes (EFNA1, BOP1, TGIF2 and STMN3 that possibly could be used for rectal cancer characterization.

  8. Upper gastrointestinal bleeding risk scores: Who, when andwhy?


    Upper gastrointestinal bleeding (UGIB) remains a significant cause of hospital admission. In order tostratify patients according to the risk of the complications,such as rebleeding or death, and to predict theneed of clinical intervention, several risk scores havebeen proposed and their use consistently recommendedby international guidelines. The use of risk scoringsystems in early assessment of patients suffering fromUGIB may be useful to distinguish high-risks patients,who may need clinical intervention and hospitalization,from low risk patients with a lower chance of developingcomplications, in which management as outpatientscan be considered. Although several scores havebeen published and validated for predicting differentoutcomes, the most frequently cited ones are the Rockallscore and the Glasgow Blatchford score (GBS). WhileRockall score, which incorporates clinical and endoscopicvariables, has been validated to predict mortality,the GBS, which is based on clinical and laboratorialparameters, has been studied to predict the need ofclinical intervention. Despite the advantages previouslyreported, their use in clinical decisions is still limited. Thisreview describes the different risk scores used in theUGIB setting, highlights the most important research,explains why and when their use may be helpful, reflectson the problems that remain unresolved and guidesfuture research with practical impact.

  9. Endoscopic hemostasis state of the art - Nonvariceal bleeding

    Goelder, Stefan Karl; Brueckner, Juliane; Messmann, Helmut


    New endoscopic techniques for hemostasis in nonvariceal bleeding were introduced and known methods further improved. Hemospray and Endoclot are two new compounds for topical treatment of bleeding. Initial studies in this area have shown a good hemostatic effect, especially in active large scale oozing bleeding, e.g., tumor bleedings. For further evaluation larger prospective studies comparing the substanced with other methods of endoscopic hemostasis are needed. For localized active arterial bleeding primary injection therapy in the area of ​​bleeding as well as in the four adjacent quadrants offers a good method to reduce bleeding activity. The injection is technically easy to learn and practicable. After bleeding activity is reduced the bleeding source can be localized more clearly for clip application. Today many different through-the-scope (TTS) clips are available. The ability to close and reopen a clip can aid towards good positioning at the bleeding site. Even more important is the rotatability of a clip before application. Often multiple TTS clips are required for secure closure of a bleeding vessel. One model has the ability to use three clips in series without changing the applicator. Severe arterial bleeding from vessels larger than 2 mm is often unmanageable with these conventional methods. Here is the over-the-scope-clip system another newly available method. It is similar to the ligation of esophageal varices and involves aspiration of tissue into a transparent cap before closure of the clip. Thus a greater vascular occlusion pressure can be achieved and larger vessels can be treated endoscopically. Patients with severe arterial bleeding from the upper gastrointestinal tract have a very high rate of recurrence after initial endoscopic treatment. These patients should always be managed in an interdisciplinary team of interventional radiologist and surgeons. PMID:26962402

    To construct a model to predict long-term bleeding events following percutaneous coronary intervention (PCI). Treatment with dual antiplatelet therapy following PCI involves balancing the benefits of preventing ischemic events with the risks of bleeding. There are no models to predict long-term bleeding events after PCI. We analyzed 1-year bleeding outcomes from 3,128 PCI procedures in the Patient Risk Information Services Manager (PRISM) observational study. Patient-reported bleeding events were categorized according to Bleeding Academic Research Consortium (BARC) definitions. Logistic regression analysis was used to develop a model predicting BARC ≥ 1 bleeding. BARC 0, 1, 2 or 3 bleeding was observed in 574 (18.4%); 2382 (76.2%); 114 (3.6%); and 58 (1.8%) patients, respectively. Compared to patients who had no bleeding, patients with BARC ≥ 1 bleeding were more often female (30 vs. 23%), Caucasian (94 vs. 83%), had a higher incidence of drug eluting stent (DES) implantation (83 vs. 76%) and warfarin therapy (7.4 vs. 3.9%), and a lower incidence of diabetes (31 vs. 45%; P-value bleeding events as well (c-statistic = 0.653). Bleeding is common in the first year after PCI, and can be predicted by pre-procedural patient characteristics and use of DES. Objective estimates of bleeding risk may help support shared decision-making with respect to stent selection and duration of antiplatelet therapy following PCI. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  11. Iatrogenic Rectal Injury During Radical Prostatectomy: Is Colostomy Inevitable End?

    Ramazan Topaktas


    Full Text Available Aim: Radical prostatectomy (RP is the gold standard treatment method for localized prostate cancer, because of its high oncological success. Iatrogenic rectal injury (IRI during RP is rarely seen, but it may causes serious complications because of the close anatomic relationship between the prostate and rectum. Aim is to present our series about management of IRI without colostomy. Material and Method: Between June 1999 and June 2013, radical retropubic prostatectomy (RRP was performed to 372 patients by a single surgeon. 10 cases (%2,6 were complicated by a rectal injury during RRP. Instant rectal closure was performed in 3 layers without a diverting colostomy, at the time of surgery. Omental vascular flap was placed between rectum and vesicourethral anastomosis. Results: The clinical stages of IRI cases were T1c, T2a and T2c in 2, 3 and 5 patients, respectively. Their preoperative Gleason scores were 6, 7 and 8 in 3, 5 and 2 patient, respectively. None of the 10 had undergone previous prostatic or rectal surgery, or received preoperative radiotherapy or hormonal therapy. Discussion: Instant diagnosis and rectal wall closures by three layers are essential for successful repair. Our technique seems as a safe, minimal invasive and highly effective option for the management of IRI.

  12. Association of anorectal malformation with anal and rectal duplication

    Karla A. Santos-Jasso


    We present three cases of rectal duplications with anorectal malforma- tion with recto-perineal fistula and colonic duplication. Two of them with delayed diagnosis and bowel obstruction, treated with laparotomy, colostomy and side-to-side anastomosis of the proximal colonic duplica- tion; in the third case the diagnosis of the colonic and rectal duplication was made during a colostomy opening. For definitive correction, the three patients underwent abdomino-perineal approach and side-to-side anastomosis of the rectal duplication, placement of the rectum within the muscle complex, and later on colostomy closure. In a fourth patient with anorectal malformation and colostomy after birth, the perineal electro-stimulation showed two muscle complexes. A posterior sagittal approach in both showed two separate blind rectal pouches; an end- to-side anastomosis of the dilated rectum was made, and the muscle complex with stronger contraction was used for the anoplasty. The posterior sagittal approach is the best surgical option to preserve the muscle complex, with a better prognosis for rectal continence.

    Robotic technology, which has recently been introduced to the field of surgery, is expected to be useful, particularly in treating rectal cancer where precise manipulation is necessary in the confined pelvic cavity. Robotic surgery overcomes the technical drawbacks inherent to laparoscopic surgery for rectal cancer through the use of multi-articulated flexible tools, three-dimensional stable camera platforms, tremor filtering and motion scaling functions, and greater ergonomic and intuitive device manipulation. Assessments of the feasibility and safety of robotic surgery for rectal cancer have reported similar operation times, blood loss during surgery, rates of postoperative morbidity, and circumferential resection margin involvement when compared with laparoscopic surgery. Furthermore, rates of conversion to open surgery are reportedly lower with increased urinary and male sexual functions in the early postoperative period compared with laparoscopic surgery, demonstrating the technical advantages of robotic surgery for rectal cancer. However, long-term outcomes and the cost-effectiveness of robotic surgery for rectal cancer have not been fully evaluated yet; therefore, large-scale clinical studies are required to evaluate the efficacy of this new technology.

  14. Patterns of metastasis in colon and rectal cancer.

    Riihimäki, Matias; Hemminki, Akseli; Sundquist, Jan; Hemminki, Kari


    Investigating epidemiology of metastatic colon and rectal cancer is challenging, because cancer registries seldom record metastatic sites. We used a population based approach to assess metastatic spread in colon and rectal cancers. 49,096 patients with colorectal cancer were identified from the nationwide Swedish Cancer Registry. Metastatic sites were identified from the National Patient Register and Cause of Death Register. Rectal cancer more frequently metastasized into thoracic organs (OR = 2.4) and the nervous system (1.5) and less frequently within the peritoneum (0.3). Mucinous and signet ring adenocarcinomas more frequently metastasized within the peritoneum compared with generic adenocarcinoma (3.8 [colon]/3.2 [rectum]), and less frequently into the liver (0.5/0.6). Lung metastases occurred frequently together with nervous system metastases, whereas peritoneal metastases were often listed with ovarian and pleural metastases. Thoracic metastases are almost as common as liver metastases in rectal cancer patients with a low stage at diagnosis. In colorectal cancer patients with solitary metastases the survival differed between 5 and 19 months depending on T or N stage. Metastatic patterns differ notably between colon and rectal cancers. This knowledge should help clinicians to identify patients in need for extra surveillance and gives insight to further studies on the mechanisms of metastasis.

  15. Patient surveillance after curative-intent surgery for rectal cancer.

    The follow-up of patients with rectal cancer after potentially curative resection has significant financial and clinical implications for patients and society. The ideal regimen for monitoring patients is unknown. We evaluated the self-reported practice patterns of a large, diverse group of experts. There is little information available describing the actual practice of clinicians who perform potentially curative surgery on rectal cancer patients and follow them after recovery. The 1795 members of the American Society of Colon and Rectal Surgeons were asked, via a detailed questionnaire, how often they request 14 discrete follow-up modalities in their patients treated for cure with TNM stage I, II, or III rectal cancer over the first five post-treatment years. 566/1782 (32%) responded and 347 of the respondents (61%) provided evaluable data. Members of the American Society of Colon and Rectal Surgeons typically follow their own patients postoperatively rather than sending them back to their referral source. Office visit and serum CEA level are the most frequently requested items for each of the first five postoperative years. Endoscopy and imaging tests are also used regularly. Considerable variation exists among these highly experienced, highly credentialed experts. The surveillance strategies reported here rely most heavily on relatively simple and inexpensive tests. Endoscopy is employed frequently; imaging tests are employed less often. The observed variation in the intensity of postoperative monitoring is of concern.

  16. Intersphincteric Resection for Low Rectal Cancer – Case Report

    Russu Cristian


    Full Text Available Introduction: Surgical treatment for low rectal cancer represents a challenge: to perform a radical resection and to preserve the sphincter’s function. We report a case of intersphincteric resection in a combined multimodality treatment for low rectal cancer, with good oncologic and functional outcome. Case presentation: We report a case of a 73 years old woman admitted in April 2014 in surgery, for low rectal cancer. The diagnostic was established by colonoscopy and malignancy confirmed by biopsy. Complete imaging was done using computed tomography and magnetic resonance to establish the exact stage of the disease. The interdisciplinary individualized treatment began with radiotherapy (total dose of 50 Gy, administered in 25 fractions followed by surgery after eight weeks. We performed intersphincteric rectal resection by a modified Schiessel technique. There were no postoperative complications and the oncologic and functional results were very good at one year follow up. Conclusions: Intersphincteric resection, in this selected case of low rectal cancer, represented an efficient surgical treatment, with good functional results and quality of life for the patient. A multidisciplinary team is an invaluable means of assessing and further managing the appropriate, tailored to the case, treatment in the aim of achieving best results.

  17. Simultaneous laparoscopic excision for rectal carcinoma and synchronous hepatic metastasis

    CHEN Kai-yun; XIANG Guo-an; WANG Han-ning; XIAO Fang-lian


    Background Rectal carcinoma patients are often accompanied by hepatic metastasis. The aim of this study was to evaluate the therapeutic efficacy of simultaneous laparoscopic excision for rectal carcinoma with synchronous hepatic metastasis.Methods A total of 41 patients with rectal carcinoma and synchronous hepatic metastasis detected by CT scan were included in this study. Among them, 23 patients underwent laparoscopic surgery and 18 patients underwent traditional open surgery to simultaneously remove the rectal tumor and hepatic metastasis lesions. All patients received postoperative adjuvant chemotherapy. All the patients were followed up from 36 to 72 months (mean 45.3 months).Results All the operations were performed successfully and no patient was turned to open surgery in laparoscopic group. The mean blood loss, the mean postoperative hospital stay, the mean blood transfusion and the mean intestinal functional recovery time showed a significant difference between the two groups (P<0.05). The 1-, 3- and 5-year survival rates were 82.6%, 43.5% and 8.6% in the laparoscopic group, without significant difference compared with the open group (77.8%, 38.9% and 0) (P>0.05).Conclusions Simultaneous laparoscopic excision for rectal carcinoma and synchronous hepatic metastasis is safe and effective with similar survival achieved by the traditional open abdominal surgery.

  18. Clopidogrel and bleeding after general surgery procedures.

    Ozao-Choy, Junko; Tammaro, Yolanda; Fradis, Martin; Weber, Kaare; Divino, Celia M


    Although many studies in the cardiothoracic literature exist about the relationship between clopidogrel and postoperative bleeding, there is scarce data in the general surgery literature. We assessed whether there are increased bleeding complications, morbidity, mortality, and resource utilization in patients who are on clopidogrel (Plavix) within 1 week before undergoing a general surgery procedure. Fifty consecutive patient charts were retrospectively reviewed after identifying patients who had pharmacy orders for clopidogrel and who underwent a general surgery procedure between 2003 and 2007. Patients who took clopidogrel within 6 days before surgery (group I, n = 28) were compared with patients who stopped clopidogrel for 7 days or more (group II, n = 22). A larger percentage of patients who took their last dose of clopidogrel within 1 week of surgery (21.4% vs 9.5%) had significant bleeding after surgery requiring blood transfusion. However, there were no significant differences between the groups in operative or postoperative blood transfusions (P = 0.12, 0.53), decreases in hematocrit (P = 0.21), hospital stay (P = 0.09), intensive care unit stay (P = 0.41), late complications (P = 0.45), or mortality (P = 0.42). Although our cohort is limited in size, these results suggest that in the case of a nonelective general surgery procedure where outcomes depend on timely surgery, clopidogrel taken within 6 days before surgery should not be a reason to delay surgery. However, careful attention must be paid to meticulous hemostasis, and platelets must be readily available for transfusion in the operating room.

  19. An Unusual Case of Gastrointestinal Bleeding

    Kristin N. Fiorino


    Full Text Available A 10-year-old boy presented with a 3-day history of worsening abdominal pain, fever, emesis and melena. Abdominal ultrasound revealed a right upper quadrant mass that was confirmed by computed tomography angiogram (CTA, which showed an 8 cm well-defined retroperitoneal vascular mass. 123Iodine metaiodobenzylguanidine (123MIBG scan indicated uptake only in the abdominal mass. Subsequent biopsy revealed a paraganglioma that was treated with chemotherapy. This case represents an unusual presentation of a paraganglioma associated with gastrointestinal (GI bleeding and highlights the utility of CTA and 123MIBG in evaluation and treatment.

  2. [Current MRI staging of rectal cancer].

    Wietek, B M; Kratt, T


    Colorectal carcinoma is the second most prevalent cause for cancer, and has very variable outcomes. Advancements in surgery, the change from adjuvant to neo-adjuvant radio-chemo-therapies as well as in clinical diagnostics have improved the prognosis for patients in a multi-modal therapy concept. An accurate primary staging including a reliable prediction of the circumferential resection margin (CRM) has established MR Imaging (MRI) beside intraluminal endoscopic ultrasound (EUS). MRI facilitates the selection of patients likely to benefit from a preoperative therapy, especially in cases of unfavorable factors. Currently the relationship of the tumor to the mesorectal fascia has become a more important prognostic factor than the T-staging, particularly for surgical therapy. In addition further prognostic factors like the depth of infiltration into the perirectal fat and the extramural venous infiltration (EMVI) have important impact on therapy and prognosis. High resolution MRI has proved useful in clarifying the relationship between the tumor and the mesorectal fascia, which represents the CRM at the total mesorectal excision (TME) especially in the upper and middle third. Preoperative evaluation of the other prognostic factors as well as the nodal status is still difficult. It is used increasingly not only for primary staging but also progressively for the monitoring of neoadjuvant therapy. The addition of diffusion weighted imaging (DWI) is an interesting option for the improvement of response evaluation. The following overview provides an introduction of MRI diagnosis as well as its importance for the evaluation of the clinically relevant prognostic factors leading to an improvement of therapy and prognosis of patients with rectal carcinoma. © Georg Thieme Verlag KG Stuttgart · New York.

  3. Results of radical surgery for rectal cancer.

    Heald, R J; Karanjia, N D


    This paper examines the hypothesis that a reduction in the distal mural margin during anterior resection for sphincter conservation in rectal cancer excision is safe, provided total mesorectal excision is undertaken with wash-out of the clamped rectum. One hundred ninety-two patients underwent anterior resection and 21 (less than 10%) patients underwent abdomino-perineal excision (APE) by one surgeon (RJH). Anterior resections were classified as "curative" (79%) and "non-curative" (21%); in the "curative" sub-group less than 4% of patients developed local recurrence. The series was retrospectively analyzed for the effect of mural margins on local recurrence with 152 patients undergoing "curative" anterior resections and 40 patients undergoing "non-curative" resections. In the 152 specimens from curative resections, 110 had a resection margin greater than 1 cm and 42 had a resection margin less than 1 cm. Four patients developed local recurrence in the greater than 1 cm margin group (95% confidence interval: 0.8%-7.8%) and no patients developed local recurrence in the less than or equal to 1 cm margin group (95% confidence interval: 0%-5.9%). In each patient with local recurrence a cause for failure was apparent. There was no statistically significant difference in local recurrence rate between the less than or equal to 1 cm margin group and the greater than 1 cm margin group. A reduction in resection margin therefore did not compromise survival after anterior resection. The significance of lateral resection margins is discussed. The role of deep radiotherapy and cytotoxics are considered.(ABSTRACT TRUNCATED AT 250 WORDS)

  6. Abnormal Uterine Bleeding: American College of Nurse-Midwives.


    Variations in uterine bleeding, termed abnormal uterine bleeding, occur commonly among women and often are physiologic in nature with no significant consequences. However, abnormal uterine bleeding can cause significant distress to women or may signify an underlying pathologic condition. Most women experience variations in menstrual and perimenstrual bleeding in their lifetimes; therefore, the ability of the midwife to differentiate between normal and abnormal bleeding is a key diagnostic skill. A comprehensive history and use of the PALM-COEIN classification system will provide clear guidelines for clinical management, evidence-based treatment, and an individualized plan of care. The purpose of this Clinical Bulletin is to define and describe classifications of abnormal uterine bleeding, review updated terminology, and identify methods of assessment and treatment using a woman-centered approach.

    Anticoagulant therapy with vitamin K antagonists (AVK) is an effective treatment and prevention of thrombosis. One of the major disadvantages of the AVK is a risk for serious bleeding. Prothrombin complex concentrates (PCC), fresh frozen plasma (FFP) and vitamin K1 are available for control of these situations. The experience of special team ofthe Scientific Center for Hematology was the basis for presented retrospective study. Three regimens of warfarin-related bleeding were compared: PCC+ VK for several bleeding, FFP+ VK for different clinical situations and VKfor light bleeding. PCC showed himself as effective and safe hemostatic agent. Transfusions of FFP were sometimes not effective, sometimes led to TACO. Supplementation of vitamin K1 for patients of I and II groups provided more stable control of hemostasis. In III group VK vas effective to stop bleeding. Two impotent sings for conclusion: necessary of laboratory monitoring, TEG first of all; individual balance of hemostasis base of bleeding or thrombotic risks.

  9. Treatment of advanced rectal cancer after renal transplantation

    Hai-Yi Liu; Xiao-Bo Liang; Yao-Ping Li; Yi Feng; Dong-Bo Liu; Wen-Da Wang


    Renal transplantation is a standard procedure for end-stage renal disease today. Due to immunosuppressive drugs and increasing survival time after renal trans-plantation, patients with transplanted kidneys carry an increased risk of developing malignant tumors. In this case report, 3 patients with advanced rectal can-cer after renal transplantation for renal failure were treated with anterior resection or abdominoperineal resection plus total mesorectal excision, followed by adjuvant chemotherapy. One patient eventually died of metastasized cancer 31 mo after therapy, although his organ grafts functioned well until his death. The other 2 patients were well during the 8 and 21 mo follow-up periods after rectal resection. We therefore strongly argue that patients with advanced rectal cancer should receive standard oncology treatment, including opera-tion and adjuvant treatment after renal transplantation. Colorectal cancer screening in such patients appears justified.

  10. Study protocol: multi-parametric magnetic resonance imaging for therapeutic response prediction in rectal cancer.

    Pham, Trang Thanh; Liney, Gary; Wong, Karen; Rai, Robba; Lee, Mark; Moses, Daniel; Henderson, Christopher; Lin, Michael; Shin, Joo-Shik; Barton, Michael Bernard


    Response to neoadjuvant chemoradiotherapy (CRT) of rectal cancer is variable. Accurate imaging for prediction and early assessment of response would enable appropriate stratification of management to reduce treatment morbidity and improve therapeutic outcomes. Use of either diffusion weighted imaging (DWI) or dynamic contrast enhanced (DCE) imaging alone currently lacks sufficient sensitivity and specificity for clinical use to guide individualized treatment in rectal cancer. Multi-parametric MRI and analysis combining DWI and DCE may have potential to improve the accuracy of therapeutic response prediction and assessment. This protocol describes a prospective non-interventional single-arm clinical study. Patients with locally advanced rectal cancer undergoing preoperative CRT will prospectively undergo multi-parametric MRI pre-CRT, week 3 CRT, and post-CRT. The protocol consists of DWI using a read-out segmented sequence (RESOLVE), and DCE with pre-contrast T1-weighted (VIBE) scans for T1 calculation, followed by 60 phases at high temporal resolution (TWIST) after gadoversetamide injection. A 3-dimensional voxel-by-voxel technique will be used to produce colour-coded ADC and K(trans) histograms, and data evaluated in combination using scatter plots. MRI parameters will be correlated with surgical histopathology. Histopathology analysis will be standardized, with chemoradiotherapy response defined according to AJCC 7th Edition Tumour Regression Grade (TRG) criteria. Good response will be defined as TRG 0-1, and poor response will be defined as TRG 2-3. The combination of DWI and DCE can provide information on physiological tumour factors such as cellularity and perfusion that may affect radiotherapy response. If validated, multi-parametric MRI combining DWI and DCE can be used to stratify management in rectal cancer patients. Accurate imaging prediction of patients with a complete response to CRT would enable a 'watch and wait' approach, avoiding surgical morbidity

  11. Risk of gastrointestinal bleeding during anticoagulant treatment.

    Lanas-Gimeno, Aitor; Lanas, Angel


    Gastrointestinal bleeding (GIB) is a major problem in patients on oral anticoagulation therapy. This issue has become even more pressing since the introduction of direct oral anticoagulants (DOACs) in 2009. Areas covered: Here we review current evidence related to GIB associated with oral anticoagulants, focusing on randomized controlled trials, meta-analyses, and post-marketing observational studies. Dabigatran 150 mg twice daily and rivaroxaban 20 mg once daily increase the risk of GIB compared to warfarin. The risk increase with edoxaban is dose-dependent, while apixaban shows apparently, no increased risk. We summarize what is known about GIB risk factors for individual anticoagulants, the location of GIB in patients taking these compounds, and prevention strategies that lower the risk of GIB. Expert opinion: Recently there has been an important shift in the clinical presentation of GIB. Specifically, upper GIB has decreased with the decreased incidence of peptic ulcers due to the broad use of proton pump inhibitors and the decreased prevalence of H. pylori infections. In contrast, the incidence of lower GIB has increased, due in part to colonic diverticular bleeding and angiodysplasia in the elderly. In this population, the addition of oral anticoagulation therapy, especially DOACs, seems to increase the risk of lower GIB.

  12. Upper gastrointestinal bleeding after open heart surgery

    Aithoussa Mahdi


    Full Text Available Objective: The occurrence of digestive complications especially upper gastrointestinal bleeding (UGIB has increased after cardiac surgery. The aim of this study was to determine the incidence of UGIB and identify the independent risk factors. Materials and Methods: We retrospectively analyzed data of 1077 patients undergoing cardiopulmonary bypass (CPB from 1994 to 2012 The group of patients with UGIB (n1 = 20 was compared with the population group (n2 = 1057. Demographic characteristics, therapeutic management, endoscopic findings, and outcomes were analyzed. Through a regression analysis we identified independent risk factors of UGIB. Results: The mean age of the group n1 was 58.2 ± 12.4 years and 50.18 ± 13.5 years in the group n2 . UGIB occurred about 13 ± 5.5 days after cardiac surgery. Gastroduodenal ulcer was the most common etiology of hemorrhage (n = 13, 65%. Renal insufficiency, previous gastric ulcer, increased lactate concentration during CPB, prolonged mechanical ventilation, use of vasopressor drug and pulmonary infection was likely contributing factors in UGIB. Conclusion: UGIB following open cardiac surgery is most frequently secondary to gastroduodenal ulceration. Many determinant factors of bleeding are incriminated. Surgeons must be aware of these factors to avoid fatal complications.

  13. Assessing Bleeding Risk in Patients Taking Anticoagulants

    Shoeb, Marwa; Fang, Margaret C.


    Anticoagulant medications are commonly used for the prevention and treatment of thromboembolism. Although highly effective, they are also associated with significant bleeding risks. Numerous individual clinical factors have been linked to an increased risk of hemorrhage, including older age, anemia, and renal disease. To help quantify hemorrhage risk for individual patients, a number of clinical risk prediction tools have been developed. These risk prediction tools differ in how they were derived and how they identify and weight individual risk factors. At present, their ability to effective predict anticoagulant-associated hemorrhage remains modest. Use of risk prediction tools to estimate bleeding in clinical practice is most influential when applied to patients at the lower spectrum of thromboembolic risk, when the risk of hemorrhage will more strongly affect clinical decisions about anticoagulation. Using risk tools may also help counsel and inform patients about their potential risk for hemorrhage while on anticoagulants, and can identify patients who might benefit from more careful management of anticoagulation.

  14. Nanocytology of rectal colonocytes to assess risk of colon cancer based on field cancerization.

    Damania, Dhwanil; Roy, Hemant K; Subramanian, Hariharan; Weinberg, David S; Rex, Douglas K; Goldberg, Michael J; Muldoon, Joseph; Cherkezyan, Lusik; Zhu, Yuanjia; Bianchi, Laura K; Shah, Dhiren; Pradhan, Prabhakar; Borkar, Monica; Lynch, Henry; Backman, Vadim


    Developing a minimally invasive and cost-effective prescreening strategy for colon cancer is critical because of the impossibility of conducting colonoscopy on the entire at-risk population. The concept of field carcinogenesis, in which normal-appearing tissue away from a tumor has molecular and, consequently, nano-architectural abnormalities, offers one attractive approach to identify high-risk patients. In this study, we investigated whether the novel imaging technique partial wave spectroscopic (PWS) microscopy could risk-stratify patients harboring precancerous lesions of the colon, using an optically measured biomarker (L(d)) obtained from microscopically normal but nanoscopically altered cells. Rectal epithelial cells were examined from 146 patients, including 72 control patients, 14 patients with diminutive adenomas, 20 patients with nondiminutive/nonadvanced adenomas, 15 patients with advanced adenomas/high-grade dysplasia, 12 patients with genetic mutation leading to Lynch syndrome, and 13 patients with cancer. We found that the L(d) obtained from rectal colonocytes was well correlated with colon tumorigenicity in our patient cohort and in an independent validation set of 39 additional patients. Therefore, our findings suggest that PWS-measured L(d) is an accurate marker of field carcinogenesis. This approach provides a potential prescreening strategy for risk stratification before colonoscopy.

    Suthar, Vishal; Burfeind, Onno; Maeder, Britta; Heuwieser, Wolfgang


    The overall objective of this study was to evaluate agreement between rectal (RT) and vaginal temperature (VT) measured with the same temperature loggers in dairy cows. Three experiments were conducted. The study began with a validation in vitro of 24 temperature loggers comparing them to a calibrated liquid-in-glass thermometer as a reference method. The association and agreement between the 24 temperature loggers with the reference method was r=0.996 (Ptemperature loggers were tested in 11 healthy post-partum cows (Experiment 2) and 12 early post-partum cows with greater body temperature (Experiment 3). Temperature loggers were set to record VT and RT at 1-min intervals. To prevent rectal and vaginal straining and potential expulsion of temperature logger an epidural injection of 2.5 ml of 2% Procain was administered. Association between RT and VT was r=0.92 (Ptemperature in Experiments 2 and 3, respectively. Furthermore the intra-class correlation coefficient between RT and VT measured with identical loggers within cows of Experiments 2 and 3 also demonstrated greater agreements (Ptemperature loggers can be used as a measure of body temperature in dairy cows.

  16. Decision-making in rectal and colorectal cancer: systematic review and qualitative analysis of surgeons' preferences.

    Broc, Guillaume; Gana, Kamel; Denost, Quentin; Quintard, Bruno


    Surgeons are experiencing difficulties implementing recommendations not only owing to incomplete, confusing or conflicting information but also to the increasing involvement of patients in decisions relating to their health. This study sought to establish which common factors including heuristic factors guide surgeons' decision-making in colon and rectal cancers. We conducted a systematic literature review of surgeons' decision-making factors related to colon and rectal cancer treatment. Eleven of 349 identified publications were eligible for data analyses. Using the IRaMuTeQ (Interface of R for the Multidimensional Analyses of Texts and Questionnaire), we carried out a qualitative analysis of the significant factors collected in the studies reviewed. Several validation procedures were applied to control the robustness of the findings. Five categories of factors (i.e. patient, surgeon, treatment, tumor and organizational cues) were found to influence surgeons' decision-making. Specifically, all decision criteria including biomedical (e.g. tumor information) and heuristic (e.g. surgeons' dispositional factors) criteria converged towards the factor 'age of patient' in the similarity analysis. In the light of the results, we propose an explanatory model showing the impact of heuristic criteria on medical issues (i.e. diagnosis, prognosis, treatment features, etc.) and thus on decision-making. Finally, the psychosocial complexity involved in decision-making is discussed and a medico-psycho-social grid for use in multidisciplinary meetings is proposed.

    Oh, Hyun Jin; Park, Jae Myung; Yoon, Seung Bae; Lee, Han Hee; Lim, Chul-Hyun; Kim, Jin Su; Cho, Yu Kyung; Lee, Bo-In; Cho, Young-Seok; Choi, Myung-Gyu


    Procedure-induced bleeding is a major complication after endoscopic intervention. The aim of this study was to investigate the risk of endoscopy-related bleeding in patients with chronic hematologic thrombocytopenia. We investigated endoscopy-related bleeding in 175 procedures performed on 108 patients with immune thrombocytopenic purpura or aplastic anemia. The outcomes were compared with those of 350 procedures on age-, sex-, and procedure-matched control subjects. Endoscopic interventions included low-risk procedures such as endoscopic biopsy and high-risk procedures including polypectomy, endoscopic resection, and endoscopic retrograde cholangiopancreatogram with sphincterotomy. Bleeding occurred in 17 (9.7%) procedures among the patients with thrombocytopenia. This rate was significantly higher than that in procedures on controls (3.1%, P = 0.003). About 60% of all bleeding events were observed within 24 h after the endoscopic procedure. Bleeding after endoscopic biopsy developed more frequently in the patient group than in the control group (7.1 vs. 0.7%; P Bleeding occurred after 20% of all high-risk procedures. The incidence of bleeding was significantly elevated in patients with a platelet count less than 50 × 10(3)/μl. Multivariate analysis revealed that high-risk procedures and low platelet count (less than 50 × 10(3)/μl) were significantly related to procedure-related bleeding. All bleeding events stopped spontaneously or were controlled with endoscopic hemostasis. Endoscopic procedure-related bleeding develops frequently in patients with chronic hematologic thrombocytopenia. Post-procedural bleeding should be observed carefully in these patients, especially when the platelet count is less than 50 × 10(3)/μl or high-risk endoscopic procedures are planned.

  20. Radiotherapy Can Cause Haemostasis in Bleeding Skin Malignancies

  3. Modern management of rectal cancer: A 2006 update

    Glen C Balch; Alex De Meo; Jose G Guillem


    The goal of this review is to outline some of the important surgical issues surrounding the management of patients with early (T1/T2 and NO), as well as locally advanced (T3/T4 and/or N1) rectal cancer. Surgery for rectal cancer continues to develop towards the ultimate goals of improved local control and overall survival, maintaining quality of life, and preserving sphincter, genitourinary, and sexual function. Information concerning the depth of tumor penetration through the rectal wall, lymph node involvement, and presence of distant metastatic disease is of crucial importance when planning a curative rectal cancer resection.Preoperative staging is used to determine the indication for neoadjuvant therapy as well as the indication for local excision versus radical cancer resection. Local excision is likely to be curative in most patients with a primary tumor which is limited to the submucosa (T1NOM0), without high-risk features and in the absence of metastatic disease. In appropriate patients, minimally invasive procedures, such as local excision, TEM, and laparoscopic resection allow for improved patient comfort, shorter hospital stays, and earlier return to preoperative activity level. Once the tumor invades the muscularis propria (T2), radical rectal resection in acceptable operative candidates is recommended.In patients with transmural and/or node positive disease (T3/T4 and/or N1) with no distant metastases,preoperative chemoradiation followed by radical resection according to the principles of TME has become widely accepted. During the planning and conduct of a radical operation for a locally advanced rectal cancer, a number of surgical management issues are considered,including: (1) total mesorectal excision (TME); (2)autonomic nerve preservation (ANP); (3) circumferential resection margin (CRM); (4) distal resection margin;(5) sphincter preservation and options for restoration of bowel continuity; (6) laparoscopic approaches; and (7)postoperative quality

  4. Changes in NAD/ADP-ribose metabolism in rectal cancer

    L. Yalcintepe


    Full Text Available The extent of ADP-ribosylation in rectal cancer was compared to that of the corresponding normal rectal tissue. Twenty rectal tissue fragments were collected during surgery from patients diagnosed as having rectal cancer on the basis of pathology results. The levels of ADP-ribosylation in rectum cancer tissue samples (95.9 ± 22.1 nmol/ml was significantly higher than in normal tissues (11.4 ± 4 nmol/ml. The level of NAD+ glycohydrolase and ADP-ribosyl cyclase activities in rectal cancer and normal tissue samples were measured. Cancer tissues had significantly higher NAD+ glycohydrolase and ADP-ribosyl cyclase activities than the control tissues (43.3 ± 9.1 vs 29.2 ± 5.2 and 6.2 ± 1.6 vs 1.6 ± 0.4 nmol mg-1 min-1. Approximately 75% of the NAD+ concentration was consumed as substrate in rectal cancer, with changes in NAD+/ADP-ribose metabolism being observed. When [14C]-ADP-ribosylated tissue samples were subjected to SDS-PAGE, autoradiographic analysis revealed that several proteins were ADP-ribosylated in rectum tissue. Notably, the radiolabeling of a 113-kDa protein was remarkably greater than that in control tissues. Poly(ADP-ribosylation of the 113-kDa protein in rectum cancer tissues might be enhanced with its proliferative activity, and poly(ADP-ribosylation of the same protein in rectum cancer patients might be an indicator of tumor diagnosis.

    Shaw, Valentina; Vandal, Alain C; Coomarasamy, Christin; Ekeroma, Alec J


    To evaluate the effectiveness of the levonorgestrel intrauterine system (LNG-IUS) in obese women with heavy menstrual bleeding in Counties Manukau Auckland area, New Zealand. Prospective observational study in a tertiary teaching hospital. Twenty women with heavy menstrual bleeding (HMB) who agreed to treatment with the LNG-IUS and had a body mass index (BMI) of >30 kg/m(2) were recruited between May and December 2014. The women completed two validated tools (Menstrual Impact Questionnaire and the Pictorial Bleeding Assessment Chart) at recruitment, 6 and 12 months follow-up. Demographic, medical and laboratory variables were obtained from the relevant CMH databases. Data on side effects and satisfaction were obtained from the women at 12 months. The median age (range) and BMI of the 20 women were 40.5 years (27-52 years) and 40.6 kg/m(2) (30-68), respectively. Three LNG-IUS were removed due to infection and pain and these women were subsequently booked for a hysterectomy. The reduction in menstrual loss was estimated at 19.7% per month (95% CI (12.5%, 26.2%); P < 0.001), which translates to 73.2% per period of 6 months (95% CI (55.3%, 83.9%)) and 92.8% per period of 12 months (95% CI (80.0%, 97.4%)). The six items in the quality of life measure improved significantly in 14 women but only 12 women were satisfied with the treatment. The LNG-IUS was an effective treatment for 67% of obese women with heavy menstrual bleeding over a 12-month period, as assessed by the reduction in menstrual bleeding and the improvement in the quality of life measures. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The following article examines the evidence regarding treatment options for patients with synchronous rectal liver metastases and suggests potential treatment algorithms.

  11. Variability of marker-based rectal dose evaluation in HDR cervical brachytherapy.

    Wang, Zhou; Jaggernauth, Wainwright; Malhotra, Harish K; Podgorsak, Matthew B


    In film-based intracavitary brachytherapy for cervical cancer, position of the rectal markers may not accurately represent the anterior rectal wall. This study was aimed at analyzing the variability of rectal dose estimation as a result of interfractional variation of marker placement. A cohort of five patients treated with multiple-fraction tandem and ovoid high-dose-rate (HDR) brachytherapy was studied. The cervical os point and the orientation of the applicators were matched among all fractional plans for each patient. Rectal points obtained from all fractions were then input into each clinical treated plan. New fractional rectal doses were obtained and a new cumulative rectal dose for each patient was calculated. The maximum interfractional variation of distances between rectal dose points and the closest source positions was 1.1 cm. The corresponding maximum variability of fractional rectal dose was 65.5%. The percentage difference in cumulative rectal dose estimation for each patient was 5.4%, 19.6%, 34.6%, 23.4%, and 13.9%, respectively. In conclusion, care should be taken when using rectal markers as reference points for estimating rectal dose in HDR cervical brachytherapy. The best estimate of true rectal dose for each fraction should be determined by the most anterior point among all fractions.

  13. The Clinical Utility of Rectal Gas Distension F-18 FDG PET/CT

    Kim, Jin Suk; Lim, Seok Tae; Jeong, Young Jin; Kim, Dong Wook; Jeong, Hwan Jeong; Sohn, Myung Hee [Chonbuk National University Medical School and Hospital, Jeonju (Korea, Republic of)


    The aim of this study was to evaluate the clinical value of rectal gas distension F-18 FDG PET/CT imaging for the differentiation of the rectal focal uptake lesions. Twenty four patients (M:F=11:13, Age 62.8{+-}12.4 years) underwent rectal gas distension F-18 FDG PET/CT, prospectively: initial image at 50-60 min after the intravenous injection of F-18 FDG and rectal distension image after the infusion of air through the anus. Focally increased uptake lesions on initial images but disappeared on rectal distension images defined a physiological uptake. For the differential evaluation of persistent focal uptake lesions on rectal distension images, colonoscopy and histopathologic examination were performed. Among the 24 patients, 27 lesions of focal rectal uptake were detected on initial images of F-18 FDG PET/CT. Of these, 7 lesions were able to judge with physiological uptake because the focal increased uptake disappeared from rectal distension image. Remaining 3 lesions were non-rectal lesions (2 lesions: rectovesical space, 1 lesion: uterine myoma). Among 17 lesions which was showed persistent increased uptake in rectal distension image, 15 lesions were confirmed as the malignant tumor (SUVmax=15.9{+-}6.8) and 2 lesions were confirmed as the benign lesions including adenoma and inflammatory disease. The rectal distension F-18 FDG PET/CT imaging could be an important noninvasive method for the differentiation of malignant and benign focal rectal uptake lesions including physiologic uptake.

    The aim of this study was to present detailed population-based survival estimates for patients with a rectal adenocarcinoma, using cancer register data supplemented with clinical data. Based on cancer register data, differences in rectal cancer survival have been reported between countries in Eur...... and detailed data in order to understand international survival differences, and cautions comparisons between large national samples and those of smaller areas........ Age standardized 5-year relative survival and multiplicative regression models for the relative excess mortality were calculated. 3888 patients were included in the survival study. Men in Denmark, Finland and Iceland had lower 5-year relative survival and poorer stage distribution compared to Norway...

    Sipahi, Mesut; Arslan, Ergin; Börekçi, Hasan; Aytekin, Faruk Önder; Külah, Bahadır; Banlı, Oktay


    Perineal procedures have higher recurrence and lower mortality rates than abdominal alternatives for the treatment of rectal prolapse. Presence of incarceration and strangulation also influences treatment choice. Perineal rectosigmoidectomy is one of the treatment options in patients with incarceration and strangulation, with low mortality and acceptable recurrence rates. This operation can be performed especially to avoid general anesthesia in old patients with co-morbidities. We aimed to present perineal rectosigmoidectomy and diverting loop colostomy in a patient with neurological disability due to spinal trauma and incarcerated rectal prolapse. PMID:27528816

    Full Text Available A 51-year-old woman with known rectal cancer currently receiving systemic chemotherapy presented with 2 weeks of worsening dyspnea on exertion. The day prior to admission she developed persistent inspiratory and expiratory wheeze. CT scan demonstrated right main stem endobronchial mass and a heterogeneous mass comprising the entire left hemithorax (Figure 1. Flexible bronchoscopy demonstrated a fungating mass at the carina extending down both main stems (Figure 2. The mass was snared and removed with cryotherapy and pathology was consistent with metastatic rectal adenocarcinoma.

    Upper gastrointestinal (GI) bleeding is a serious complication that sometimes occurs after percutaneous radiologic gastrostomy (PRG). We evaluated the incidence of bleeding complications after a PRG and its management including transcatheter arterial embolization (TAE). We retrospectively reviewed 574 patients who underwent PRG in our institution between 2000 and 2010. Eight patients (1.4%) had symptoms or signs of upper GI bleeding after PRG. The initial presentation was hematemesis (n = 3), melena (n = 2), hematochezia (n = 2) and bloody drainage through the gastrostomy tube (n = 1). The time interval between PRG placement and detection of bleeding ranged from immediately after to 3 days later (mean: 28 hours). The mean decrease in hemoglobin concentration was 3.69 g/dL (range, 0.9 to 6.8 g/dL). In three patients, bleeding was controlled by transfusion (n = 2) or compression of the gastrostomy site (n = 1). The remaining five patients underwent an angiography because bleeding could not be controlled by transfusion only. In one patient, the bleeding focus was not evident on angiography or endoscopy, and wedge resection including the tube insertion site was performed for hemostasis. The other four patients underwent prophylactic (n = 1) or therapeutic (n = 3) TAEs. In three patients, successful hemostasis was achieved by TAE, whereas the remaining one patient underwent exploration due to persistent bleeding despite TAE. We observed an incidence of upper GI bleeding complicating the PRG of 1.4%. TAE following conservative management appears to be safe and effective for hemostasis.

  18. Recent Update of Embolization of Upper Gastrointestinal Tract Bleeding


    Nonvariceal upper gastrointestinal (UGI) bleeding is a frequent complication with significant morbidity and mortality. Although endoscopic hemostasis remains the initial treatment modality, severe bleeding despite endoscopic management occurs in 5-10% of patients, necessitating surgery or interventional embolotherapy. Endovascular embolotherapy is now considered the first-line therapy for massive UGI bleeding that is refractory to endoscopic management. Interventional radiologists need to be familiar with the choice of embolic materials, technical aspects of embolotherapy, and the factors affecting the favorable or unfavorable outcomes after embolotherapy for UGI bleeding.

  19. Photocoagulation in the treatment of bleeding peptic ulcer

    Otto, Wlodzimierz; Paczkowski, Pawel M.


    The authors present their experience in the endoscopic laser photocoagulation of bleeding peptic ulcer. From 1991 to June 1995, 203 patients admitted for UGI bleeding from peptic ulcer have been treated by this method. The source of bleeding was confirmed by endoscopy. The patients were divided into two groups: actively bleeding peptic ulcer (group IA and IB according to Forrest's classification) and ulcer with stigmata of recent bleeding (group IIA/IIB). The former group consisted of 106 patients, among whom over 40 percent (45 patients) presented signs of hypovolemic shock on admission. Nd:YAG laser (Surgical Laser Technologies) was used in a continuous mode with a contact (8 - 20 watts) or non-contact (over 50 watts) method of coagulation. In actively bleeding patients photocoagulation resulted in stopping the hemorrhage in 95 (90%). Recurrent bleeding occurred in 16 cases; in 9 of them it was stopped by repeated photocoagulation. In this group 18 patients required surgical intervention. The mortality was of 10.3% (11 patients). In 97 patients with recent bleeding stigmata photocoagulation provoked heavy hemorrhage in 3 (in 2 cases stopped by prolonged coagulation). In 9 of the remaining 94 patients recurrent bleeding occurred. Nine patients required surgical intervention. Mortality in this group was of 6%.

    Full Text Available A 29-year-old patient with cervical ectopic pregnancy (CEP presented as "suspected" cervical mass, and irregular vaginal bleeding was directed to a gynecologic oncologist for consultation. During the examination a massive bleeding occurred. After an unsuccessful attempt to stop the bleeding with a balloon catheter and vaginal tamponade, a total abdominal hysterectomy was performed. The predisposing factors, the differential diagnostic possibilities and the clinical approaches in CEP are discussed. Total abdominal hysterectomy is the procedure of choice for treatment of cervical pregnancy under conditions of urgency and life-threatening bleeding.
