    Full Text Available The incidence of presacral bleeding during rectal mobilization is low, but such bleeding may be massive and even fatal. Haemostasis can be difficult to achieve using conventional methods because of the complex interlacing of the venous network at the sacral periosteum. Historically, pelvic packing and metallic thumbtacks have been the more commonly used methods in our institution. However, the need for repeat surgery to remove the packs and the difficulties encountered in tack application have forced us to explore other methods. In 1994, the procedure termed muscle fragment welding, which uses electrocautery through a rectus muscle fragment, was introduced to control presacral bleeding. From January 1999 to February 2002, six of 416 patients undergoing pelvic surgery in our institution developed massive presacral haemorrhage and, therefore, this technique was used. Haemostasis was immediate and permanent. No major untoward postoperative events such as re-bleeding or infection were noted. One case developed a second-degree burn in the right elbow due to a misplaced ground conduction plate. Rectus muscle fragment welding is, in our experience, an effective and practical method of controlling presacral haemorrhage.

    Objectives Rectal bleeding is an alarming event both for the child and parents. It is hypothesized that colonoscopy instead of sigmoidoscopy and adding esophago-gastro-duodenoscopy in case of accompanying complaints, improves the diagnostic accuracy in children with prolonged rectal bleeding.

    The purpose of this study was to analyze rectal bleeding prognostic factors associated with prostate brachytherapy (PB) or in combination with external-beam radiation therapy (EBRT) and to examine dosimetric indications associated with rectal bleeding. The study included 296 patients followed up for >36 months (median, 48 months). PB was performed alone in 252 patients and in combination with EBRT in 44 patients. PB combined with EBRT is indicated for patients with a Gleason score >6. The prescribed dose was 144 Gy for monotherapy and 110 Gy for PB+EBRT (44-46 Gy). Although 9.1% who received monotherapy had 2.3% grade 2 rectal bleeding, 36.3% who received combined therapy had 15.9% grade 2 rectal bleeding. Combined therapy was associated with higher incidence of rectal bleeding (P=0.0049) and higher percentage of grade 2 bleeding (P=0.0005). Multivariate analysis revealed that R-150 was the only significant factor for rectal bleeding, and modified Radiation Therapy Oncology Group (RTOG) grade in monotherapy and biologically equivalent dose (BED) were significant for combined therapy. Moreover, grade 2 rectal bleeding increased significantly at D90 >130 Gy. Although R-150 was the significant prognostic factor for rectal bleeding and modified RTOG rectal toxicity grade, BED was the significant prognostic factor for modified RTOG rectal toxicity grade.

    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 ∼ 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 (ρ > 0.0432). The total

    Aglumin was administered to 20 cases which had rectal bleeding following radiotherapy. The results were as follows. Rectal bleeding decreased in 16 of 20 cases (80%): remarkably effective, 15%; effective, 25%; slightly effective, 40%. Bleeding time decreased in 11 cases (55%). Rumpel-Leede test gave remarkable improvement in 10 of 14 cases which had been abnormal (71.4%). Platelet increased in 18 of 20 cases (90%). Liver function test and peripheral blood findings showed no remarkable changes. No side effects such as intestinal disturbance etc were noted. In the series of symptomatic treatment for rectal disturbance resulting from radiotherapy, this drug had considerable effect of hemostasis. It was concluded that this drug is useful in combined use with other antiphlogistics, analgesic, and hematinic etc. (Ueda, J.)

    Purpose: To investigate the incidence and severity of rectal bleeding after high-dose hypofractionated radiotherapy (RT) for prostate cancer, and to explore the factors affecting the incidence of Grade 2 or worse rectal bleeding. Methods and materials: The data of 52 patients who had been treated by external beam RT for localized prostate cancer between 1999 and 2002 were analyzed. All the patients had received hypofractionated external beam RT to a total dose of 69 Gy in 3-Gy fractions, three fractions weekly. The clinical and dosimetric factors affecting the incidence of Grade 2 or worse late rectal bleeding were analyzed by univariate and multivariate analyses. The effect of the percentage of the whole rectal volume receiving 30%, 50%, 80%, and 90% of the prescribed radiation dose (V 30 , V 50 , V 80 , and V 90 , respectively) on the incidence of rectal bleeding was evaluated. Results: Of the 52 patients, 13 (25%) developed Grade 2 or worse rectal bleeding. One patient who needed laser coagulation and blood transfusion for the treatment of rectal bleeding was classified as having Grade 3 rectal bleeding. The median time to the development of Grade 2 or worse rectal bleeding was 11 months. The results of the univariate analysis revealed that the presence of a history of diabetes mellitus (p 30 ≥ 60%, V 50 ≥ 40% (p 80 ≥ 25%, and V 90 ≥ 15% (p < 0.001) were statistically significant risk factors for the occurrence of Grade 2 or worse rectal bleeding. The results of the multivariate analysis revealed that a history of diabetes mellitus was the most statistically significant risk factor for the occurrence of rectal bleeding after hypofractionated RT for prostate cancer (p < 0.05). Conclusion: A history of diabetes mellitus was the most statistically significant risk factor for the occurrence of Grade 2 or worse rectal bleeding after high-dose hypofractionated RT, although dosimetric factors were also closely associated with the risk of rectal bleeding

    Purpose: To better define the efficacy and safety of argon plasma coagulation (APC), specifically for brachytherapy-related proctitis, we reviewed the clinical course of 7 patients treated for persistent rectal bleeding. Approximately 2-10% of prostate cancer patients treated with 125 I or 103 Pd brachytherapy will develop radiation proctitis. The optimum treatment for patients with persistent bleeding is unclear from the paucity of available data. Prior reports lack specific dosimetric information, and patients with widely divergent forms of radiation were grouped together in the analyses. Methods and Materials: Seven patients were treated with APC at the Veterans Affairs Puget Sound Health Care System and the University of Washington from 1997 to 1999 for persistent rectal bleeding due to prostate brachytherapy-related proctitis. Four patients received supplemental external beam radiation, delivered by a four-field technique. A single gastroenterologist at the Veterans Affairs Puget Sound Health Care System treated 6 of the 7 patients. If the degree of proctitis was limited, all sites of active bleeding were coagulated in symptomatic patients. An argon plasma coagulator electrosurgical system was used to administer treatments every 4-8 weeks as needed. The argon gas flow was set at 1.6 L/min, with an electrical power setting of 40-45 W. Results: The rectal V100 (the total rectal volume, including the lumen, receiving the prescription dose or greater) for the 7 patients ranged from 0.13 to 4.61 cc. Rectal bleeding was first noticed 3-18 months after implantation. APC (range 1-3 sessions) was performed 9-22 months after implantation. Five patients had complete resolution of their bleeding, usually within days of completing APC. Two patients had only partial relief from bleeding, but declined additional APC therapy. No patient developed clinically evident progressive rectal wall abnormalities after APC, (post-APC follow-up range 4-13 months). Conclusions: Most

    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.

    Purpose: The new short Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) patient-reported health-related quality of life (HRQOL) tool has removed the rectal bleeding question from the previous much longer version, EPIC-26. Herein, we assess the impact of losing the dedicated rectal bleeding question in 2 independent prospective multicenter cohorts. Methods and Materials: In a prospective multicenter test cohort (n=865), EPIC-26 patient-reported HRQOL data were collected for 2 years after treatment from patients treated with prostate radiation therapy from 2003 to 2011. A second prospective multicenter cohort (n=442) was used for independent validation. A repeated-effects model was used to predict the change from baseline in bowel summary scores from longer EPIC instruments using the change in EPIC-CP bowel summary scores with and without rectal bleeding scores. Results: Two years after radiation therapy, 91% of patients were free of bleeding, and only 2.6% reported bothersome bleeding problems. Correlations between EPIC-26 and EPIC-CP bowel scores were very high (r"2=0.90-0.96) and were statistically improved with the addition of rectal bleeding information (r"2=0.94-0.98). Considering all patients, only 0.2% of patients in the test cohort and 0.7% in the validation cohort reported bothersome bleeding and had clinically relevant HRQOL changes missed with EPIC-CP. However, of the 2.6% (n=17) of men with bothersome rectal bleeding in the test cohort, EPIC-CP failed to capture 1 patient (6%) as experiencing meaningful declines in bowel HRQOL. Conclusions: Modern prostate radiation therapy results in exceptionally low rates of bothersome rectal bleeding, and <1% of patients experience bothersome bleeding and are not captured by EPIC-CP as having meaningful HRQOL declines after radiation therapy. However, in the small subset of patients with bothersome rectal bleeding, the longer EPIC-26 should strongly be considered, given its superior

    Rectal bleeding often heralds serious colonic disease. The literature suggests that colonoscopy is superior to barium enema plus sigmoidoscopy, although no good comparative studies exist. Seventy one patients with overt rectal bleeding had prospectively flexible sigmoidoscopy, double contrast barium enema and colonoscopy completed independently. Against the gold standard, the sensitivity and specificity of colonoscopy were 0.69 and 0.78 respectively for a spectrum of colonic lesions, while fo...

    Nowadays, the de nition of patient-speci c constraints in prostate cancer radiotherapy planning are solely based on dose-volume histogram (DVH) parameters. Nevertheless those DVH models lack of spatial accuracy since they do not use the complete 3D information of the dose distribution. The goal of the study was to propose an automatic work ow to de ne patient-speci c rectal sub-regions (RSR) involved in rectal bleeding (RB) in case of prostate cancer radiotherapy. A multi-atlas database spanning the large rectal shape variability was built from a population of 116 individuals. Non-rigid registration followed by voxel-wise statistical analysis on those templates allowed nding RSR likely correlated with RB (from a learning cohort of 63 patients). To de ne patient-speci c RSR, weighted atlas-based segmentation with a vote was then applied to 30 test patients. Results show the potentiality of the method to be used for patient-speci c planning of intensity modulated radiotherapy (IMRT).

    Full Text Available Purpose: Colorectal cancer (CRC incidence rates are steadily increasing in Nigeria. Organized screening is still largely unused because of financial and logistical barriers; most CRCs are detected by symptoms. One symptom of CRC is rectal bleeding. This study sought to determine health-seeking behavior and barriers to care in patients with rectal bleeding in Nigeria. This study also surveyed physicians to determine major breakdowns in access to care. Methods: The recruitment process for this study involved patients referred for colonoscopy because of rectal bleeding as well as response to a media advertisement for a free colonoscopy. Physicians were recruited at the African Research Group for Oncology meeting. Patient responses were scored on the basis of knowledge of rectal bleeding. The physician questionnaire was supporting information and mainly descriptive in nature. Results: A total of 82 patients and 45 physicians participated in this study. Less than 40% of patients knew that rectal bleeding could be caused by cancer. Major barriers to care were resolution of the symptom (42%, no consideration of the bleeding as problematic (40%, and financial constraint (22%. Education was strongly correlated with knowledge of rectal bleeding and health-seeking behavior. Although physicians regularly saw patients with rectal bleeding, most of them provided a differential diagnosis of hemorrhoids and few referred patients for colonoscopy. Conclusion: General awareness about the signs of colorectal cancer is lacking. This demonstrates the strong need for patient education programs about this issue. Physicians should also receive additional training on differentiation of a potential cancer diagnosis from something more benign, such as hemorrhoids.

    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.

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

    To assess whether Foley catheterization of the rectum after transrectal ultrasound (TRUS)-guided prostate biopsy decreases complication rates. Between June 2000 and September 2006, 275 consecutive patients were evaluated after undergoing TRUS-guided prostate biopsy. All procedures were performed on an outpatient basis. Patients were divided into two groups. In the first group (n = 134), a Foley catheter was inserted into the rectum and inflated to 50 cm(3) after TRUS-guided biopsy. In the second group (n = 141), catheterization was performed without balloon placement. Rectal bleeding, hematuria, hematospermia, infection, and acute urinary retention rates were compared between groups. The mean ages of the patients were 63.3 years +/- 5.6 and 62.1 years +/- 7.2 years in the Foley catheter group and control group, respectively (P = .112). Hematuria, hematospermia, infection, and rectal bleeding occurred in 31 (23.1%), 30 (22.4), nine (6.7%), and two patients (1.5%), respectively, in the Foley catheter group; and in 36 (25.5%), 36 (25.5%), 11 (7.8%), and 25 patients (17.7%), respectively, in the control group. The incidences of infection, hematuria, and hematospermia were not significantly different between groups (P > .05). In contrast, the rectal bleeding rate was significantly lower in the Foley catheter group (1.5%) than in the control group (17.7%; P = .001). Although it has no effect on other complications, TRUS-guided prostate biopsy with rectal Foley catheterization is a useful, practical method to decrease or prevent rectal bleeding.

    Rectal duplication cysts are rare, thought to be due to defects in embryologic development, and often associated with other structural abnormalities. Clues to the existence of a rectal cyst are mainly due to bowel compression and presence of ectopic gastric mucosa within the cyst, leading to rectal bleeding. The diagnosis of a rectal duplication cyst requires a high index of suspicion. Confirming the diagnosis can be difficult based on the location of the cyst. Efforts to confirm the diagnosis include digital rectal examination, computed tomography, magnetic resonance imaging, ultrasonography, and Meckel scan. Surgical resection is the treatment of choice, especially because of the cyst’s potential for malignant transformation. Because of the cyst’s proximal location to the nerves innervating the anal canal and sphincters, surgical resection can lead to fecal incontinence.

    The aim of this study was to develop a model exploiting artificial neural networks (ANNs) to correlate dosimetric and clinical variables with late rectal bleeding in prostate cancer patients undergoing radical radiotherapy and to compare the ANN results with those of a standard logistic regression (LR) analysis. 718 men included in the AIROPROS 0102 trial were analyzed. This multicenter protocol was characterized by the prospective evaluation of rectal toxicity, with a minimum follow-up of 36 months. Radiotherapy doses were between 70 and 80 Gy. Information was recorded for comorbidity, previous abdominal surgery, use of drugs and hormonal therapy. For each patient, a rectal dose-volume histogram (DVH) of the whole treatment was recorded and the equivalent uniform dose (EUD) evaluated as an effective descriptor of the whole DVH. Late rectal bleeding of grade ≥ 2 was considered to define positive events in this study (52 of 718 patients). The overall population was split into training and verification sets, both of which were involved in model instruction, and a test set, used to evaluate the predictive power of the model with independent data. Fourfold cross-validation was also used to provide realistic results for the full dataset. The LR was performed on the same data. Five variables were selected to predict late rectal bleeding: EUD, abdominal surgery, presence of hemorrhoids, use of anticoagulants and androgen deprivation. Following a receiver operating characteristic analysis of the independent test set, the areas under the curves (AUCs) were 0.704 and 0.655 for ANN and LR, respectively. When evaluated with cross-validation, the AUC was 0.714 for ANN and 0.636 for LR, which differed at a significance level of p = 0.03. When a practical discrimination threshold was selected, ANN could classify data with sensitivity and specificity both equal to 68.0%, whereas these values were 61.5% for LR. These data provide reasonable evidence that results obtained with

    Presacral venous haemorrhage during rectal movement is low, but is often massive, and even fatal. Our objective is the "in vitro" determination of the results of electrocoagulation applied to a fragment of muscle on the sacral bone surface during rectal resection due to a malignant neoplasm of the rectum. Single-pole coagulation was applied "in vitro" with the selector at maximum power on a 2×2 cms muscle fragment, applied to the anterior side of the IV sacral vertebra until reaching boiling point. The method was used on 6 patients with bleeding of the presacral venous plexus. In the "in vitro" study, boiling point was reached in 90 seconds from applying the single-pole current on the muscle fragment. Electrocoagulation was applied to a 2×2 cm rectal muscle fragment in 6 patients with presacral venous haemorrhage, using pressure on the surface of the presacral bone, with the stopping of the bleeding being achieved in all cases. The use of indirect electrocoagulation on a fragment of the rectus abdominis muscle is a straightforward and highly effective technique for controlling presacral venous haemorrhage.

    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.

    Eighty-seven outpatients with non-massive rectal bleeding or asymptomatic positive fecal occult blood were evaluated with 35 cm flexible sigmoidoscopy, double contrast barium enema (DBCE) and colonoscopy. 82% had hemorrhoids and 35% harbored colorectal neoplasia. The combination of flexible sigmoidoscopy and DCBE missed none of 7 malignant lesions. However, 35% of benign polyps ≥ 1 cm and 60.5% of those < 1 cm were not detected by this combination. The presence of hemorrhoids should not prevent a search for colon neoplasia and colonoscopy is the preferred method. (orig.)

    Massive gastrointestinal bleeding is an emergency that can sometimes require immediate surgery. We report the first case, to the best of our knowledge, of massive rectal bleeding due to Yersinia enterocolitica, requiring ileocecal resection. A 41-year-old North African woman was admitted to our emergency department for massive rectal bleeding. She had a history of an iron deficiency anemia of unknown cause, and diarrhea 2 months before the admission. On admission to our emergency unit, she was in a state of hemodynamic collapse. An examination showed discolored conjunctivas, massive rectal bleeding with clots and no abdominal pain. The first medical treatment included the use of noradrenaline. An upper gastrointestinal endoscopy was performed and did not show any lesions. Computed tomography of her abdomen showed significant and hypervascular wall thickening of her terminal ileum suggestive of a tumor. Because her massive rectal bleeding worsened and her collapse persisted, an exploratory laparotomy and ileocecal resection were immediately performed on the patient. Histopathological analysis showed enteritis caused by Yersinia enterocolitica. Her outcome was favorable. Enteritis due to Yersinia enterocolitica can take a pseudotumoral form and mislead the diagnosis of gastrointestinal bleeding.

    Purpose: Rectal bleeding is the most common late sequelae of high-dose 3D conformal treatment (3DCRT) for prostate cancer and may limit attempts to improve local control by dose escalation. The clinical course of this complication is reported including time to onset, response to treatment, duration of morbidity, and multivariate analysis for predictors. Methods and Materials: From March 1989 to June 1995, 670 patients with prostate cancer were treated with 3DCRT at Fox Chase Cancer Center. Eighty-nine patients developed Grade 2 or Grade 3 complications due to rectal bleeding and are analyzed. Multivariate analysis results for predictors of Grade 2 and 3 rectal bleeding are reported as well as time to development, response to initial and retreatment, and duration of morbidity. Results: The median time to occurrence is not significantly different (p = 0.09) for Grade 2 (13 months, range 4-41 months) compared to Grade 3 rectal bleeding (18 months, range 4-40 months), while the corresponding median duration of symptoms was significantly different (p < 0.0001) being 1 month (range 1-12) vs. 10 months (1-34) for Grade 2 and Grade 3 bleeding, respectively. For Grade 2 bleeding, medication or coagulation was highly effective as initial or retreatment resolving 66 of 73 patients. For Grade 3 bleeding, three patients responded without medication following blood transfusion only, while with multiple coagulations and medication 12 of 16 patients improved to ≤ Grade 1. Multivariate analysis demonstrates that dose is the only significant factor associated with Grade 2 (p = 0.01) or Grade 3 (p = 0.01) rectal bleeding. Of seven nonresponders to treatment for Grade 2 bleeding, three have died of intercurrent disease at 10, 19, and 26 months, while four are alive with continuing Grade 2 bleeding at 12, 14, 15, and 30 months after onset. The four nonresponders to treatment for Grade 3 bleeding continue to bleed 1, 9, 32, and 35 months after the third coagulation despite continuing

    Purpose: Serious late morbidity (Grade (3(4))) from the conformal treatment of prostate cancer has been reported in <1% to 6% of patients. This study demonstrates that the reported frequency of Grade (3(4)) complications varies by the morbidity scale selected and that no existing morbidity scale adequately represents chronic rectal bleeding, which is our most frequent persisting late sequela of high dose conformal treatment. Materials and Methods: Between (5(89)) and (12(93)), 352 patients with T1-3 NXM0 prostate cancers were treated with our 4-field conformal technique without special rectal blocking. This technique includes a 1 cm margin from the CTV to the PTV in all directions. The median follow-up for these patients was 38 mos (4 to 78), and the median ICRU reporting point dose was 74 Gy (63 to 81). Patients are followed at six month intervals, and no patient is lost to follow-up. Three morbidity scales are assessed, the RTOG, the late effects group (LENT), and our modification of the LENT (FC-LENT). This modification registers chronic rectal bleeding requiring more than two coagulations as a grade 3 event. Estimates for Grade (3(4)) late GI complication rates were determined using Kaplan-Meier methodology. Differences in morbidity rates were evaluated using the log-rank test and differences in time to latency of complications were evaluated using the nonparametric Wilcoxon test. The duration of severe symptoms with chronic rectal bleeding is measured from the first to the last transrectal coagulation. Results: Sixteen patients developed Grade (3(4)) complications by one of the three morbidity scales. Two patients required surgery (colostomy, sigmoid resection), 5 required a transfusion, and 9 required more than two coagulations. The median latency to the third coagulation (plus or minus transfusions) was 24 mos (17 to 40). The median duration of bleeding between the first and last coagulation was 6 mos (3 to 25), illustrating the chronicity of this problem

    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

    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. 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. 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 < 0.001) and bleeding stopped in 5 (42%). After adequate periods of observation, steroid suppositories/enemas are expected to be effective. However, short

    Purpose: Serious late morbidity (Grade (3(4))) from the conformal treatment of prostate cancer has been reported in <1% to 6% of patients based on existing late gastrointestinal (GI) morbidity scales. None of the existing morbidity scales include our most frequently observed late GI complication, which is chronic rectal bleeding requiring multiple fulgerations. This communication documents the frequency of rectal bleeding requiring multiple fulgerations and illustrates the variation in reported late serious GI complication rates by the selection of morbidity scale. Methods and Materials: Between May 1989 and December 1993, 352 patients with T1-T3 nonmetastatic prostate cancers were treated with our four-field conformal technique without special rectal blocking. This technique includes a 1-cm margin from the clinical target volume (CTV) to the planning target volume (PTV) in all directions. The median follow-up for these patients was 36 months (range 2-76), and the median center of prostate dose was 74 Gy (range 63-81). Three morbidity scales are assessed: the Radiation Therapy Oncology Group (RTOG), the Late Effects Normal Tissue Task Force (LENT), and our modification of the LENT (FC-LENT). This modification registers chronic rectal bleeding requiring at least one blood transfusion and/or more than two coagulations as a Grade 3 event. Estimates for Grade (3(4)) late GI complication rates were determined using Kaplan-Meier methodology. The duration of severe symptoms with chronic rectal bleeding is measured from the first to the last transrectal coagulation. Latency is measured from the end of radiotherapy to surgery, first blood transfusion, or third coagulation procedure. Results: Sixteen patients developed Grade (3(4)) complications by one of the three morbidity scales. Two patients required surgery (colostomy or sigmoid resection), three required multiple blood transfusions, two required one or two blood transfusions, and nine required at least three

    Purpose: Dose-volume histograms (DVHs) may be very useful tools for estimating probability of normal tissue complications (NTCP), but there is not yet an agreed upon method for their analysis. This study introduces a statistical method of aggregating and analyzing primary data from DVHs and associated outcomes. It explores the dose-volume relationship for NTCP of the rectum, using long-term data on rectal wall bleeding following prostatic irradiation. Methods and Materials: Previously published data were reviewed and updated on 41 patients with Stages T3 and T4 prostatic carcinoma treated with photons followed by perineal proton boost, including dose-volume histograms (DVHs) of each patient's anterior rectal wall and data on the occurrence of postirradiation rectal bleeding (minimum FU > 4 years). Logistic regression was used to test whether some individual combination of dose and volume irradiated might best separate the DVHs into categories of high or low risk for rectal bleeding. Further analysis explored whether a group of such dose-volume combinations might be superior in predicting complication risk. These results were compared with results of the 'critical volume model', a mathematical model based on assumptions of underlying radiobiological interactions. Results: Ten of the 128 tested dose-volume combinations proved to be 'statistically significant combinations' (SSCs) distinguishing between bleeders (14 out of 41) and nonbleeders (27 out of 41), ranging contiguously between 60 CGE (Cobalt Gray Equivalent) to 70% of the anterior rectal wall and 75 CGE to 30%. Calculated odds ratios for each SSC were not significantly different across the individual SSCs; however, analysis combining SSCs allowed segregation of DVHs into three risk groups: low, moderate, and high. Estimates of probabilities of normal tissue complications (NTCPs) based on these risk groups correlated strongly with observed data (p = 0.003) and with biomathematical model-generated NTCPs

    Purpose: Investigating the correlation between dosimetric/clinical parameters and late rectal bleeding in patients treated with adjuvant or salvage radiotherapy after radical prostatectomy. Methods and Materials: Data of 154 consecutive patients, including three-dimensional treatment planning and dose-volume histograms (DVHs) of the rectum (including filling), were retrospectively analyzed. Twenty-six of 154 patients presenting a (full) rectal volume >100 cc were excluded from the analysis. All patients considered for the analysis (n=128) were treated at a nominal dose equal to 66.6-70.2 Gy (ICRU dose 68-72.5 Gy; median 70 Gy) with conformal (n=76) or conventional (n=52) four-field technique (1.8 Gy/fr). Clinical parameters such as diabetes mellitus, acute rectal bleeding, hypertension, age, and hormonal therapy were considered. Late rectal bleeding was scored using a modified Radiation Therapy Oncology Group scale, and patients experiencing ≥Grade 2 were considered bleeders. Median follow-up was 36 months (range 12-72). Mean and median rectal dose were considered, together with rectal volume and the % fraction of rectum receiving more than 50, 55, 60, and 65 Gy (V50, V55, V60, V65, respectively). Median and quartile values of all parameters were taken as cutoff for statistical analysis. Univariate (log-rank) and multivariate (Cox hazard model) analyses were performed. Results: Fourteen of 128 patients experienced ≥Grade 2 late bleeding (3-year actuarial incidence 10.5%). A significant correlation between a number of cutoff values and late rectal bleeding was found. In particular, a mean dose ≥54 Gy, V50 ≥63%, V55 ≥57%, and V60 ≥50% was highly predictive of late bleeding (p≤0.01). A rectal volume <60 cc and type of treatment (conventional vs. conformal) were also significantly predictive of late bleeding (p=0.05). Concerning clinical variables, acute bleeding (p < 0.001) was significantly related to late bleeding, and a trend was found for

    Purpose: Late rectal bleeding is the most common sequelae of high dose 3D conformal treatment (3DCRT) for prostate cancer and limits attempts to improve local control by dose escalation. The clinical course of this complication is reported including time to onset, response to treatment, duration of morbidity and risk factor analysis by multivariate analysis. Materials and Methods: From March, 1989 to June 1996, 670 patients with prostate cancer were treated with 3DCRT. Eighty-nine patients developed grade 2 or 3 complications due to rectal bleeding and are analyzed (Grade 2 LENT scale, Grade 3 Fox Chase modification of LENT including >2 coagulations as Grade 3). They are compared to 581 patients without Grade 2,3 morbidity in multivariate analysis. Time to development, response to initial and retreatment and duration of morbidity are tabulated. Results: The median time to occurrence is not significantly different (p=.09) for Grade 2 (13 mo. range 4-41 mo.) compared to Grade 3 (18 mo. range 4-40 mo.). The corresponding median duration of symptoms >Grade 1 were significantly different (p=.0001) being 1 month (range 1-<12) versus 10 months (1-34) respectively. The response to treatment and retreatment is shown in Table 1. For Grade 2 complications medication or coagulation was highly effective as initial or retreatment resolving 66 of 73 patients. For Grade 3 a few responded to only transfusion and with multiple coagulations and medication (12(16)) patients improved to ≤ Grade 1. Multivariate analysis demonstrates that dose is the only significant factor associated with Grade 2 (LENT) (p=.01) or Grade 3 (FC-LENT) (p=.01) complication. Lack of response to treatment was associated with hypertension on univariate analysis only. Of 7 non-responders to treatment of Grade 2 bleeding, 3 have died of intercurrent disease at 10, 19 and 26 months while 4 are alive with continuing Grade 2 bleeding at 26, 34, 41 and 45 months after onset. Of 4 non-responders to treatment of

    BACKGROUNDThere is uncertainty whether a focus on modifiable bleeding risk factors offers better prediction of major bleeding than other existing bleeding risk scores.METHODSThis study compared a score based on numbers of the modifiable bleeding risk factors recommended in the 2016 European...... guidelines ("European risk score") versus other published bleeding risk scores that have been derived and validated in atrial fibrillation subjects (HEMORR2HAGES, HAS-BLED, ATRIA, and ORBIT) in a large hospital-based cohort of Chinese inpatients with atrial fibrillation.RESULTSThe European score had modest...... predictive ability for major bleeding (c-index 0.63, 95% confidence interval 0.56-0.69) and intracranial hemorrhage (0.72, 0.65-0.79) but nonsignificantly (and poorly) predicted extracranial bleeding (0.55, 0.54-0.56; P = .361). The HAS-BLED score was superior to predict bleeding events compared...

    In patients undergoing radiotherapy for localized prostate cancer, dose-volume histograms and clinical variables were examined to search for correlations between radiation treatment planning parameters and late rectal bleeding. We analyzed 129 patients with localized prostate cancer who were managed from 2002 to 2010 at our institution. They were treated with 3D conformal radiation therapy (3D-CRT, 70 Gy/35 fractions, 55 patients) or intensity-modulated radiation therapy (IMRT, 76 Gy/38 fractions, 74 patients). All radiation treatment plans were retrospectively reconstructed, dose-volume histograms of the rectum were generated, and the doses delivered to the rectum were calculated. Time to rectal bleeding ranged from 9 - 53 months, with a median of 18.7 months. Of the 129 patients, 33 patients had Grade 1 bleeding and were treated with steroid suppositories, while 25 patients with Grade 2 bleeding received argon plasma laser coagulation therapy (APC). Three patients with Grade 3 bleeding required both APC and blood transfusion. The 5-year incidence rate of Grade 2 or 3 rectal bleeding was 21.8% for the 3D-CRT group and 21.6% for the IMRT group. Univariate analysis showed significant differences in the average values from V65 to V10 between Grades 0 - 1 and Grades 2 - 3. Multivariate analysis demonstrated that patients with V65 ≥ 17% had a significantly increased risk (P = 0.032) of Grade 2 or 3 rectal bleeding. Of the 28 patients of Grade 2 or 3 rectal bleeding, 17 patients (60.7%) were cured by a single session of APC, while the other 11 patients required two sessions. Thus, none of the patients had any further rectal bleeding after the second APC session. (author)

    Gastrointestinal duplication is an infrequent congenital abnormality. Colonic and tubular duplications are the least common. In neonates there are few described cases. It's difficult to identify the duplication preoperatively and a standard surgical approach has not been developped. We report a neonate with bleeding of the digestive tube who presented a colonic duplication who required multiple diagnostic test before the diagnosis was made for colonoscopy. Laparotomy showed a total tubular duplication of the right, transverse and left colon with proximal and distal communication. Exclusion of the duplicated segment was performed, but three months after the operation, subocclusion due to stenosis of the colonic distal loop was developed. This finding was confirmed by a second colonoscopy and septum was partially removed. The study implies that CD, though uncommon, should be included in the differential diagnosis of rectal bleeding and the importance of the colonoscopy in the diagnosis and treatment of this malformation.

    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 cm 3 , 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 cm 3 ,(Ρ =0.02) , odds ratio of 2.26 per .5 cm 3 (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.

    Acute lower gastrointestinal bleeding is a common reason for emergency hospital admission, and identification of patients at low risk of harm, who are therefore suitable for outpatient investigation, is a clinical and research priority. We aimed to develop and externally validate a simple risk score to identify patients with lower gastrointestinal bleeding who could safely avoid hospital admission. We undertook model development with data from the National Comparative Audit of Lower Gastrointestinal Bleeding from 143 hospitals in the UK in 2015. Multivariable logistic regression modelling was used to identify predictors of safe discharge, defined as the absence of rebleeding, blood transfusion, therapeutic intervention, 28 day readmission, or death. The model was converted into a simplified risk scoring system and was externally validated in 288 patients admitted with lower gastrointestinal bleeding (184 safely discharged) from two UK hospitals (Charing Cross Hospital, London, and Hammersmith Hospital, London) that had not contributed data to the development cohort. We calculated C statistics for the new model and did a comparative assessment with six previously developed risk scores. Of 2336 prospectively identified admissions in the development cohort, 1599 (68%) were safely discharged. Age, sex, previous admission for lower gastrointestinal bleeding, rectal examination findings, heart rate, systolic blood pressure, and haemoglobin concentration strongly discriminated safe discharge in the development cohort (C statistic 0·84, 95% CI 0·82-0·86) and in the validation cohort (0·79, 0·73-0·84). Calibration plots showed the new risk score to have good calibration in the validation cohort. The score was better than the Rockall, Blatchford, Strate, BLEED, AIMS65, and NOBLADS scores in predicting safe discharge. A score of 8 or less predicts a 95% probability of safe discharge. We developed and validated a novel clinical prediction model with good discriminative

    Full Text Available Diarrhea and fecal incontinence are common in critically ill patients and present a challenging problem in patient management. The Flexi-Seal® Fecal Management System is a device to divert the stools away from the patient, thus improving the care to patients with fecal incontinence. There have been only few case reports describing the complications with the use of this device. Here, we present a case of a 77-year-old woman who was admitted due to massive hematochezia while on anticoagulation. She was found to have a large rectal ulcer caused by the Flexi-Seal device, used during the last hospital stay for fecal incontinence. Flexi-Seal device can be effective for the management of incontinence; however, caution should be exercised during handling and pressure from the retention balloon should be relieved periodically.

    With the advent of modern radiation techniques, we have been able to deliver a higher prescribed radiotherapy dose for localized prostate cancer without severe adverse reactions. We reviewed and analyzed the change of toxicity profiles of external beam radiation therapy (EBRT) from the literature. Late rectal bleeding is the main adverse effect, and an incidence of >20% of Grade ≥2 adverse events was reported for 2D conventional radiotherapy of up to 70 Gy. 3D conformal radiation therapy (3D-CRT) was found to reduce the incidence to ∼10%. Furthermore, intensity-modulated radiation therapy (IMRT) reduced it further to a few percentage points. However, simultaneously, urological toxicities were enhanced by dose escalation using highly precise external radiotherapy. We should pay more attention to detailed quality of life (QOL) analysis, not only with respect to rectal bleeding but also other specific symptoms (such as urinary incontinence and impotence), for two reasons: (1) because of the increasing number of patients aged >80 years, and (2) because of improved survival with elevated doses of radiotherapy and/or hormonal therapy; age is an important prognostic factor not only for prostate-specific antigen (PSA) control but also for adverse reactions. Those factors shift the main focus of treatment purpose from survival and avoidance of PSA failure to maintaining good QOL, particularly in older patients. In conclusion, the focus of toxicity analysis after radiotherapy for prostate cancer patients is changing from rectal bleeding to total elaborate quality of life assessment. (author)

    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

    Purpose: To determine the predictive risk factors for Grade 2 or worse rectal bleeding after high-dose-rate brachytherapy (HDR-BT) combined with hypofractionated external-beam radiotherapy (EBRT) for prostate cancer using dose–volume histogram analysis. Methods and Materials: The records of 216 patients treated with HDR-BT combined with EBRT were analyzed. The treatment protocols for HDR-BT were 5 Gy × five times in 3 days or 7 Gy × three, 10.5 Gy × two, or 9 Gy × two in 2 days. The EBRT doses ranged from 45 to 51 Gy with a fractional dose of 3 Gy. Results: In 20 patients Grade 2 or worse rectal bleeding developed, and the cumulative incidence rate was 9% at 5 years. By converting the HDR-BT and EBRT radiation doses into biologic effective doses (BED), the BED 3 at rectal volumes of 5% and 10% in the patients who experienced bleeding were significantly higher than those in the remaining 196 patients. Univariate analysis showed that a higher rectal BED 3–5% and the use of fewer needles in brachytherapy were correlated with the incidence of bleeding, but BED 3–5% was found to be the only significant factor on multivariate analysis. Conclusions: The radiation dose delivered to small rectal lesions as 5% is important for predicting Grade 2 or worse rectal bleeding after HDR-BT combined with EBRT for prostate cancer.

    The purpose of this study was to evaluate late rectal bleeding and genitourinary (GU) morbidity in patients consecutively treated with combined high-dose-rate (HDR) brachytherapy and external beam radiation therapy (EBRT). Data from 80 patients treated consecutively from October 2000 to May 2004 were analyzed. The median age was 69 years old, median follow-up 31 months, ranging from 17-59 months. All patients received endocrine therapy before radiation therapy. The patients were divided into low-, intermediate- and high-risk groups (4/24/52 patients) according to the risk factors defined by T-classification, prostatic specific antigen (PSA) and Gleason score. Fractionation schedules for HDR brachytherapy were prospectively changed, and EBRT was fixed with 3 Gy fractions to 51 Gy. The distribution of fractionation was scheduled as follows; 5 Gy x 5 times in 14 patients, 7 Gy x 3 times in 19 patients, and 9 Gy x 2 times in 47 patients. The rectal bleeding was graded using the toxicity criteria of the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer while the genitourinary morbidities were graded using the toxicity criteria of the Common Terminology Criteria for Adverse Events v.3.0. Grade 2 or worse rectal bleeding developed in 9 patients (11.3%) with the 2-year actuarial probability at 11.2%. Grade 2 and 3 rectal bleeding was recognized in 8 and 1 patients, respectively. Grade 3 morbidity developed in the biopsied sites that were performed in the other hospital. No significant difference was observed in any HDR brachytherapy fractionation schedule. Grade 2 or worse GU morbidities were recognized in 30 patients (37.5%), consisting of 29 Grade 2 patients and 1 Grade 3 patient. Twenty-one patients in Grade 2 morbidity had an increase in the frequency of urination or nocturia, and urethral strictures developed in 3 patients. The 3-year actuarial probability of urethral stricture was 6.0%. One patient experienced Grade 3

    Purpose: Accurate modeling of rectal complications based on dose-volume histogram (DVH) data are necessary to allow safe dose escalation in radiotherapy of prostate cancer. We applied different equivalent uniform dose (EUD)-based and dose-volume-based normal tissue complication probability (NTCP) models to rectal wall DVHs and follow-up data for 319 prostate cancer patients to identify the dosimetric factors most predictive for Grade ≥ 2 rectal bleeding. Methods and Materials: Data for 319 patients treated at the William Beaumont Hospital with three-dimensional conformal radiotherapy (3D-CRT) under an adaptive radiotherapy protocol were used for this study. The following models were considered: (1) Lyman model and (2) logit-formula with DVH reduced to generalized EUD (3) serial reconstruction unit (RU) model (4) Poisson-EUD model, and (5) mean dose- and (6) cutoff dose-logistic regression model. The parameters and their confidence intervals were determined using maximum likelihood estimation. Results: Of the patients, 51 (16.0%) showed Grade 2 or higher bleeding. As assessed qualitatively and quantitatively, the Lyman- and Logit-EUD, serial RU, and Poisson-EUD model fitted the data very well. Rectal wall mean dose did not correlate to Grade 2 or higher bleeding. For the cutoff dose model, the volume receiving > 73.7 Gy showed most significant correlation to bleeding. However, this model fitted the data more poorly than the EUD-based models. Conclusions: Our study clearly confirms a volume effect for late rectal bleeding. This can be described very well by the EUD-like models, of which the serial RU- and Poisson-EUD model can describe the data with only two parameters. Dose-volume-based cutoff-dose models performed worse

    Multiple models have been developed to predict pathologic complete response (pCR) in locally advanced rectal cancer patients. Unfortunately, validation of these models normally omit the implications of cohort differences on prediction model performance. In this work, we will perform a prospective validation of three pCR models, including information whether this validation will target transferability or reproducibility (cohort differences) of the given models. We applied a novel methodology, the cohort differences model, to predict whether a patient belongs to the training or to the validation cohort. If the cohort differences model performs well, it would suggest a large difference in cohort characteristics meaning we would validate the transferability of the model rather than reproducibility. We tested our method in a prospective validation of three existing models for pCR prediction in 154 patients. Our results showed a large difference between training and validation cohort for one of the three tested models [Area under the Receiver Operating Curve (AUC) cohort differences model: 0.85], signaling the validation leans towards transferability. Two out of three models had a lower AUC for validation (0.66 and 0.58), one model showed a higher AUC in the validation cohort (0.70). We have successfully applied a new methodology in the validation of three prediction models, which allows us to indicate if a validation targeted transferability (large differences between training/validation cohort) or reproducibility (small cohort differences). © 2017 American Association of Physicists in Medicine.

    Given the challenges involved in obtaining accurate bleeding histories, attempts at standardization have occurred and the value of quantifying hemorrhagic symptoms has been recognized. An extensive validated bleeding questionnaire (MCMDM-1VWD) was condensed by eliminating all details that did not directly affect the bleeding score (BS) and the correlation between the two versions was tested. Additionally, the diagnostic utility of the condensed version was prospectively tested. Data on 259 individuals who were administered the questionnaire are presented here; 217 being prospectively investigated for von Willebrand disease (VWD) (group 1) and 42 previously known to have type 1, 2 or 3 VWD (group 2). Of the 217 prospectively investigated, 35 had positive BS (> or =4) and 182 had negative scores. Seven individuals (all with positive BS) had laboratory results consistent with type 1 VWD. This results in a sensitivity of 100% and a specificity of 87%. The positive predictive value is 0.20 and the negative predictive value is 1. The correlation between the full MCMDM-1VWD and condensed versions is excellent (Spearman's 0.97, P type 2 > type 1 VWD (anova P < 0.001). There is a strong inverse relationship between VWF:Ag level and BS (Spearman's -0.411, P < 0.001). The Condensed MCMDM-1VWD Bleeding Questionnaire is an efficient, effective tool in the evaluation of patients for VWD.

    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.

    Full Text Available We aimed to evaluate the generalizability of NOBLADS, a severe lower gastrointestinal bleeding (LGIB prediction model which we had previously derived when working at a different institution, using an external validation cohort. NOBLADS comprises the following factors: non-steroidal anti-inflammatory drug use, no diarrhea, no abdominal tenderness, blood pressure ≤ 100 mmHg, antiplatelet drug use, albumin < 3.0 g/dL, disease score ≥ 2, and syncope.We retrospectively analyzed 511 patients emergently hospitalized for acute LGIB at the University of Tokyo Hospital, from January 2009 to August 2016. The areas under the receiver operating characteristic curves (ROCs-AUCs for severe bleeding (continuous and/or recurrent bleeding were compared between the original derivation cohort and the external validation cohort.Severe LGIB occurred in 44% of patients. Several clinical factors were significantly different between the external and derivation cohorts (p < 0.05, including background, laboratory data, NOBLADS scores, and diagnosis. The NOBLADS score predicted the severity of LGIB with an AUC value of 0.74 in the external validation cohort and one of 0.77 in the derivation cohort. In the external validation cohort, the score predicted the risk for blood transfusion need (AUC, 0.71, but was not adequate for predicting intervention need (AUC, 0.54. The in-hospital mortality rate was higher in patients with a score ≥ 5 than in those with a score < 5 (AUC, 0.83.Although the external validation cohort clinically differed from the derivation cohort in many ways, we confirmed the moderately high generalizability of NOBLADS, a clinical risk score for severe LGIB. Appropriate triage using this score may support early decision-making in various hospitals.

    Full Text Available A digital rectal examination is a highly important procedure carried out on infants and children during visits to the gastroenterology clinic, but is often accompanied with physiologic and psychologic trauma in patients, along with being diagnostically inaccurate in the results obtained from it. In order to avoid causing discomfort to the patients, and to improve the accuracy of the results obtained from a DRE, we have articulated a much safer and more precise method of conducting the examination. The use of a 16 French Foley Catheter in the collection of stool samples during a DRE has proved to be an innovative technique, which eliminates discomfort in patients, provides a less stressful environment for both the physician and the family of the patient, along with providing unambiguous results for the FOBT. The use of this technique will not only produce accurate results, but will also eliminate reasons to avoid such an important examination due to the uncomfortable situation a normal DRE would cause.

    Purpose: To compare the rectal and prostatic radiation doses for a prospective series of 503 patients, 44 of whom developed persistent rectal bleeding, and 2 of whom developed rectal-prostatic fistulas. Methods and Materials: The 503 patients were randomized and treated by implantation with 125 I vs. 103 Pd alone (n = 290) or to 103 Pd with 20 Gy vs. 44 Gy supplemental external beam radiotherapy (n = 213) and treated at the Puget Sound Veterans Affairs Medical Center (n = 227), Schiffler Cancer Center (n 242) or University of Washington (n = 34). Patients were treated between September 1998 and October 2001 and had a minimum of 24 months of follow-up. The patient groups were treated concurrently. Treatment-related morbidity was monitored by mailed questionnaires, using standard American Urological Association and Radiation Therapy Oncology Group criteria, at 1, 3, 6, 12, 18, and 24 months. Patients who reported Grade 1 or greater Radiation Therapy Oncology Group rectal morbidity were interviewed by telephone to clarify details regarding their rectal bleeding. Those who reported persistent bleeding, lasting for >1 month were included as having Grade 2 toxicity. Three of the patients with rectal bleeding required a colostomy, two of whom developed a fistula. No patient was lost to follow-up. The rectal doses were defined as the rectal volume in cubic centimeters that received >50%, 100%, 200%, or 300% of the prescription dose. The rectum was considered as a solid structure defined by the outer wall, without attempting to differentiate the inner wall or contents. Results: Persistent rectal bleeding occurred in 44 of the 502 patients, 32 of whom (73%) underwent confirmatory endoscopy. In univariate analysis, multiple parameters were associated with late rectal bleeding, including all rectal brachytherapy indexes. In multivariate analysis, however, only the rectal volume that received >100% of the dose was significantly predictive of bleeding. Rectal fistulas occurred

    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. En la mayoría de las ocasiones está producida por patología anorrectal benigna. Nuestro objetivo era determinar la necesidad de realizar pruebas endoscópicas en pacientes con rectorragia. Pacientes y métodos: se incluyeron de forma prospectiva durante tres meses todos los pacientes que eran derivados desde la Atención Primaria por rectorragia. En todos los pacientes se realizó historia clínica y exploración física que incluía tacto rectal, analítica básica y una colonoscopia. Resultados: se incluyeron 126 pacientes con una edad media de 49,2 años (19-80. El tacto rectal fue anormal en 75 (59,5%. En 22 pacientes se encontró patología severa o positiva (lesiones neoplásicas, angiodisplasias y enfermedad inflamatoria

    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

    The aim of this study was to externally validate the four commonly used scoring systems in the risk stratification of patients with upper gastrointestinal bleed (UGIB). Patients of UGIB who underwent endoscopy within 24 h of presentation were stratified prospectively using the pre-endoscopy Rockall score (PRS) >0, complete Rockall score (CRS) >2, Glasgow Blatchford bleeding scores (GBS) >3, and modified GBS (m-GBS) >3 scores. Patients were followed up to 30 days. Prognostic accuracy of the scores was done by comparing areas under curve (AUC) in terms of overall risk stratification, re-bleeding, mortality, need for intervention, and length of hospitalization. One hundred and seventy-five patients were studied. All four scores performed better in the overall risk stratification on AUC [PRS = 0.566 (CI: 0.481-0.651; p-0.043)/CRS = 0.712 (CI: 0.634-0.790); p0.001); m-GBS = 0.802 (CI: 0.734-0.871; pbleed [AUC-0.679 (CI: 0.579-0.780; p = 0.003)]. All the scoring systems except PRS were found to be significantly better in detecting 30-day mortality with a high AUC (CRS = 0.798; p-0.042)/GBS = 0.833; p-0.023); m-GBS = 0.816; p-0.031). All four scores demonstrated significant accuracy in the risk stratification of non-variceal patients; however, only GBS and m-GBS were significant in variceal etiology. Higher cutoff scores achieved better sensitivity/specificity [RS > 0 (50/60.8), CRS > 1 (87.5/50.6), GBS > 7 (88.5/63.3), m-GBS > 7(82.3/72.6)] in the risk stratification. GBS and m-GBS appear to be more valid in risk stratification of UGIB patients in this region. Higher cutoff values achieved better predictive accuracy.

    To develop and assess the accuracy of risk prediction models to diagnose endometrial cancer in women having postmenopausal bleeding (PMB). A retrospective cohort study of 4383 women in a One-stop PMB clinic from a university teaching hospital in Hong Kong. Clinical risk factors, transvaginal ultrasonic measurement of endometrial thickness (ET) and endometrial histology were obtained from consecutive women between 2002 and 2013. Two models to predict risk of endometrial cancer were developed and assessed, one based on patient characteristics alone and a second incorporated ET with patient characteristics. Endometrial histology was used as the reference standard. The split-sample internal validation and bootstrapping technique were adopted. The optimal threshold for prediction of endometrial cancer by the final models was determined using a receiver-operating characteristics (ROC) curve and Youden Index. The diagnostic gain was compared to a reference strategy of measuring ET only by comparing the AUC using the Delong test. Out of 4383 women with PMB, 168 (3.8%) were diagnosed with endometrial cancer. ET alone had an area under curve (AUC) of 0.92 (95% confidence intervals [CIs] 0.89-0.94). In the patient characteristics only model, independent predictors of cancer were age at presentation, age at menopause, body mass index, nulliparity and recurrent vaginal bleeding. The AUC and Youdens Index of the patient characteristic only model were respectively 0.73 (95% CI 0.67-0.80) and 0.72 (Sensitivity=66.5%; Specificity=68.9%; +ve LR=2.14; -ve LR=0.49). ET, age at presentation, nulliparity and recurrent vaginal bleeding were independent predictors in the patient characteristics plus ET model. The AUC and Youdens Index of the patient characteristic plus ET model where respectively 0.92 (95% CI 0.88-0.96) and 0.71 (Sensitivity=82.7%; Specificity=88.3%; +ve LR=6.38; -ve LR=0.2). Comparison of AUC indicated that a history alone model was inferior to a model using ET alone

    We evaluated the rate of significant colonic and extra-colonic abnormalities at computed tomography colonography (CTC), according to symptoms and age. We retrospectively evaluated 7361 consecutive average-risk subjects (3073 males, average age: 60.3 ± 13.9; range 18–96 years) for colorectal cancer (CRC) who underwent CTC. They were divided into three groups according to clinical symptoms: 1343 asymptomatic individuals (group A), 899 patients with at least one “alarm” symptom for CRC, including rectal bleeding and unexplained weight loss (group C), and 5119 subjects with other gastrointestinal symptoms (group B). Diagnostic and test-positive rates of CTC were established using optical colonoscopy (OC) and/or surgery as reference standard. In addition, clinically significant extra-colonic findings were noted. 903 out of 7361 (12%, 95% confidence interval (CI) 0.11–0.13) subjects had at least one clinically significant colonic finding at CTC. CTC true positive fraction and false positive fraction were respectively 637/642 (99.2%, 95%CI 0.98–0.99) and 55/692 (7.95%, 95%CI 0.05–0.09). The pooled test-positive rate in group C (138/689, 20.0%, 95%CI 0.17–0.23) was significantly higher than in both groups A (79/1343, 5.9%, 95%CI 0.04–0.07) and B (420/5329, 7.5%, 95%CI 0.07–0.08) (p < 0.001). Aging and male gender were associated to a higher test positive rate. The rate of clinically significant extra-colonic findings was significantly higher in group C (44/689, 6.4%, 95%CI 0.04–0.08) versus groups A (26/1343, 1.9%, 95%CI 0.01–0.02) and B (64/5329, 1.2%, 95%CI 0.01–0.02) (p < 0.001). Both test-positive and significant extra-colonic finding rates at CTC are significantly increased in the presence of “alarm” gastrointestinal symptoms especially in older patients

    To externally validate previously published predictive models of the risk of developing metachronous peritoneal carcinomatosis (PC) after resection of nonmetastatic colon or rectal cancer and to update the predictive model for colon cancer by adding new prognostic predictors. Data from all patients with Stage I-III colorectal cancer identified from a population-based database in Stockholm between 2008 and 2010 were used. We assessed the concordance between the predicted and observed probabilities of PC and utilized proportional-hazard regression to update the predictive model for colon cancer. When applied to the new validation dataset (n = 2011), the colon and rectal cancer risk-score models predicted metachronous PC with a concordance index of 79% and 67%, respectively. After adding the subclasses of pT3 and pT4 stage and mucinous tumour to the colon cancer model, the concordance index increased to 82%. In validation of external and recent cohorts, the predictive accuracy was strong in colon cancer and moderate in rectal cancer patients. The model can be used to identify high-risk patients for planned second-look laparoscopy/laparotomy for possible subsequent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

    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

    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.

    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.

    To evaulate the efficacy and safety of emergent superselective transcatheter embolization for controlling massive colonic bleeding. Six of the seven patients who had symptom of massive gastrointestinal bleeding underwent emergent transcatheter embolization for control of the bleeding. Gastrointestinal bleeding in these patients was originated from various colonic diseases: rectal cancer(n=1), proctitis(n=1), benign ulcer(n=1), mucosal injury by ventriculoperitoneal shunt(n=1), and unknown(n=2). All patients except one with rectal cancer were critically ill. Superselective embolization were done by using Gelfoam particles and/or coils. The vessels embolized were ileocolic artery(n=1). superior rectal artery(n=2), inferior rectal artery (n=1), and middle and inferior rectal arteries(n=1). Hemostasis was successful immediately in all patients. Two underwnet surgery due to recurrent bleeding developed 3 days after the procedure(n=1) or in associalion with underlying rectal cancer(n=1). On surgical specimen of two cases, there was no mucosal ischemic change. Transcatheter embolization is a safe and effective treatment of method for the control of massive colonic bleeding

    2008-01-01

    We compared endometrial sampling by pipelle endometrial curette withconventional dilatation and curettage (D and C) in patients with abnormaluterine bleeding. Endometrial sampling with pipelle curette was performed on100 patients followed by formal D and C. Samples were labeled as A and B,respectively, and sent to a histopathologist who was blinded as to the methodof sampling. The histopathology reports of both samples were compared, takingD and C as the gold standard. An adequate sample was obtained in 98% of casesby pipelle and in 100% of cases by D and C. Pipelle had sensitivity,specificity, positive predictive value of 100% for diagnosing endometrialcarcinoma, hyperplasia and secretory endometrium. Pipelle also had highdiagnostic sensitivity, specificity and negative predictive value (100%, 98%and 100%, respectively) for hyperplasia with atypia and low sensitivity (57%)and positive predictive value (57%), but high specificity (97%) and negativepredictive value (97%) for endometritis. Similarly, for proliferativeendometrium, the pipelle technique had values of 94% and 93% for sensitivityand specificity, respectively. Both samples labeled as inadequate forhistology by pipelle were polyps on the D and C report. Difficultendotracheal intubation was encountered in two cases of D and C. No othercomplications of the procedure were observed. The pipelle is a safe devicefor getting an adequate endometrial sample for histology, with a highsensitivity and specificity for detection of hyperplasia and malignancy.(author)

    Full Text Available Solitary rectal ulcer syndrome (SRUS is a benign disease that is often misdiagnosed. It is characterized by a combination of symptoms, endoscopic findings and histology. Patients present with constipation, rectal bleeding, mucous discharge, pain and a sensation of incomplete defecation. There are many different manifestations of this disease, with or without rectal prolapse. We report an unusual presentation of SRUS as a circular stenosis in a middle-aged male.

    The 12-gene Recurrence Score assay is a validated predictor of recurrence risk in stage II and III colon cancer patients. We conducted a prospectively designed study to validate this assay for prediction of recurrence risk in stage II and III rectal cancer patients from the Dutch Total Mesorectal Excision (TME) trial. RNA was extracted from fixed paraffin-embedded primary rectal tumor tissue from stage II and III patients randomized to TME surgery alone, without (neo)adjuvant treatment. Recurrence Score was assessed by quantitative real time-polymerase chain reaction using previously validated colon cancer genes and algorithm. Data were analysed by Cox proportional hazards regression, adjusting for stage and resection margin status. All statistical tests were two-sided. Recurrence Score predicted risk of recurrence (hazard ratio [HR] = 1.57, 95% confidence interval [CI] = 1.11 to 2.21, P = .01), risk of distant recurrence (HR = 1.50, 95% CI = 1.04 to 2.17, P = .03), and rectal cancer-specific survival (HR = 1.64, 95% CI = 1.15 to 2.34, P = .007). The effect of Recurrence Score was most prominent in stage II patients and attenuated with more advanced stage (P(interaction) ≤ .007 for each endpoint). In stage II, five-year cumulative incidence of recurrence ranged from 11.1% in the predefined low Recurrence Score group (48.5% of patients) to 43.3% in the high Recurrence Score group (23.1% of patients). The 12-gene Recurrence Score is a predictor of recurrence risk and cancer-specific survival in rectal cancer patients treated with surgery alone, suggesting a similar underlying biology in colon and rectal cancers. © The Author 2014.

    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

    Rectal duplication cysts are rare congenital anomalies. They constitute only 4% of the total gastrointestinal anomalies. They usually present in childhood. The common presenting symptoms are mass or pressure effects like constipation, tenesmus, urinary retention, local infection or bleeding due to presence of ectopic gastric mucosa. We are reporting a rare presenting symptom of rectal duplication cyst in a 4-year-old boy/toddler who presented with rectal prolapse. He also had bleeding per rectum. Rectal examination revealed a soft mass palpable in the posterior rectal wall. CT scan showed a cystic mass in the posterior wall of the rectum. It was excised trans-anally and the postoperative recovery was uneventful. Biopsy report showed rectal duplication cyst.

    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.

    Background: Bleeding from anus is usually referred as rectal bleeding but actually rectal bleeding is defined as bleeding from lower colon or rectum, which means bleeding from a place distal to ligament of Treitz. This study was conducted to determine the frequency of different causes of rectal bleeding in patients at Ayub Teaching Hospital, Abbottabad. Methods: One hundred and seventy-five patients with evidence of rectal bleed, without gender discrimination were selected by non-probability convenient sampling from the out-patient department and general medical wards. Patients with suspected upper GI source of bleeding; acute infectious bloody diarrhoea and any coagulopathy were excluded from the study. All patients were subjected to fibre optic colonoscopy after preparation of the gut and findings were recorded. Where necessary, biopsy samples were also taken. Diagnosis was based on colonoscopic findings. Results: A total of 175 patients (92 males and 83 females) with mean age 35.81±9.18 years were part of the study. Colonoscopy showed abnormal findings in 150 (85.7%) patients. The commonest diagnosis was haemorrhoids, which was found in 39 (22.3%) patients. It was followed by inflammatory bowel disease (IBD) in 30 (17.1%) patients, solitary rectal ulcer in 13 (7.4%) patients and polyps in 25 (14.3%) patients. Other less frequent findings were non-specific inflammation and fungating growths in rectum. Conclusion: Haemorrhoids was the leading cause of bleeding per rectum in this study, followed by evidence of IBD while infrequent findings of polyps and diverticuli indicate that these are uncommon in this region.

    The aim was to develop and validate a simple scoring system evaluating the impact of colostomy dysfunction on quality of life (QOL) in patients with a permanent stoma after rectal cancer treatment. In this population-based study, 610 patients with a permanent colostomy after previous rectal cancer treatment during the period 2001-2007 completed two questionnaires: (i) the basic stoma questionnaire consisting of 22 items about stoma function with one anchor question addressing the overall stoma impact on QOL and (ii) the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) C30. Answers from half of the cohort were used to develop the score and subsequently validated on the remaining half. Logistic regression analyses identified and selected items for the score and multivariate analysis established the score value allocated to each item. The colostomy impact score includes seven items with a total range from 0 to 38 points. A score of ≥ 10 indicates major colostomy impact (Major CI). The score has a sensitivity of 85.7% for detecting patients with significant stoma impact on QOL. Using the EORTC QLQ scales, patients with Major CI experienced significant impairment in their QOL compared to the Minor CI group. This new scoring system appears valid for the assessment of the impact on QOL from having a permanent colostomy in a Danish rectal cancer population. It requires validation in non-Danish populations prior to its acceptance as a valuable patient-reported outcome measure for patients internationally.

    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.

    Purpose: To evaluate the feasibility of magnetic resonance–guided high-intensity focused ultrasound (MR-HIFU) mild hyperthermia in deep tissue targets for enhancing radiation therapy and chemotherapy in the context of recurrent rectal cancer. A preclinical study was performed to evaluate the safety and performance of MR-HIFU mild hyperthermia. A prospective imaging study was performed in volunteers with rectal cancer to evaluate MR thermometry quality near the rectum and accessibility of rectal tumors using MR-HIFU. Methods and Materials: Mild hyperthermia was performed in pig thigh (9 sonications, 6 pigs) using a clinical MR-HIFU system. Targets near the rectal wall and deep thigh were evaluated. Thermal maps obtained in 6 planes every 3.2 seconds were used to control sonications in 18-mm diameter treatment regions at temperatures of 42°C to 42.5°C for 10 to 60 minutes. Volunteer imaging-only studies to assess the quality of MR thermometry (without heating) were approved by the institutional research ethics board. Anatomic and MR thermometry images were acquired in consenting volunteers with rectal cancer. In 3 of 6 study participants, rectal filling with saline was used to reduce motion-related MR thermometry artifacts near the tumor. Results: In pigs, mean target temperature matched the desired hyperthermia temperature within 0.2°C; temporal standard deviation ≤0.5°C. With optimized control thresholds, no undesired tissue damage was observed. In human volunteers, MR temperature measurements had adequate precision and stability, especially when rectal filling was used to reduce bowel motion. Conclusions: In pigs, MR-HIFU can safely deliver mild hyperthermia (41°C-43°C) to a targeted volume for 30 minutes. In humans, careful patient selection and preparation will enable adequate targeting for recurrent rectal cancers and sufficient MR temperature mapping stability to control mild hyperthermia. These results enable human trials of MR-HIFU hyperthermia.

    To evaluate the impact of four different rectum contouring techniques and rectal toxicities in patients with treated with 3D conformal radiotherapy (3DCRT). Clinical and dosimetric data were evaluated for 94 patients who received a total dose 3DCRT of 70 Gy, and rectal doses were compared in four different rectal contouring techniques: the prostate-containing CT sections (method 1); 1 cm above and below the planning target volume (PTV) (method 2); 110 mm starting from the anal verge (method 3); and from the anal verge to the sigmoid flexure (method 4). The percentage of rectal volume receiving RT doses (30–70 Gy) and minimum, mean rectal doses were assessed. Median age was 69 years. Percentage of rectal volume receiving high doses (≥ 70 Gy) were higher with the techniques that contoured smaller rectal volumes. In methods 2 and 3, the percentage of rectal volume receiving ≥ 70 Gy was significantly higher in patients with than without rectal bleeding (method 2: 30.8% vs. 22.5%, respectively (p = 0.03); method 3: 26.9% vs. 18.1%, respectively (p = 0.006)). Mean rectal dose was significant predictor of rectal bleeding only in method 3 (48.8 Gy in patients with bleeding vs. 44.4 Gy in patients without bleeding; p = 0.02). Different techniques of rectal contouring significantly influence the calculation of radiation doses to the rectum and the prediction of rectal toxicity. Rectal volume receiving higher doses (≥ 70 Gy) and mean rectal doses may significantly predict rectal bleeding for techniques contouring larger rectal volumes, as was in method 3

    Jean-Bernard Delobel

    Full Text Available To identify predictors of acute and late rectal toxicity following prostate cancer radiotherapy (RT, while integrating the potential impact of RT technique, dose escalation, and moderate hypofractionation, thus enabling us to generate a nomogram for individual prediction.In total, 972 patients underwent RT for localized prostate cancer, to a total dose of 70 Gy or 80 Gy, using two different fractionations (2 Gy or 2.5 Gy/day, by means of several RT techniques (3D conformal RT [3DCRT], intensity-modulated RT [IMRT], or image-guided RT [IGRT]. Multivariate analyses were performed to identify predictors of acute and late rectal toxicity. A nomogram was generated based on the logistic regression model used to predict the 3-year rectal toxicity risk, with its accuracy assessed by dividing the cohort into training and validation subgroups.Mean follow-up for the entire cohort was 62 months, ranging from 6 to 235. The rate of acute Grade ≥2 rectal toxicity was 22.2%, decreasing when combining IMRT and IGRT, compared to 3DCRT (RR = 0.4, 95%CI: 0.3-0.6, p<0.01. The 5-year Grade ≥2 risks for rectal bleeding, urgency/tenesmus, diarrhea, and fecal incontinence were 9.9%, 4.5%, 2.8%, and 0.4%, respectively. The 3-year Grade ≥2 risk for overall rectal toxicity increased with total dose (p<0.01, RR = 1.1, 95%CI: 1.0-1.1 and dose per fraction (2Gy vs. 2.5Gy (p = 0.03, RR = 3.3, 95%CI: 1.1-10.0, and decreased when combining IMRT and IGRT (RR = 0.50, 95% CI: 0.3-0.8, p<0.01. Based on these three parameters, a nomogram was generated.Dose escalation and moderate hypofractionation increase late rectal toxicity. IMRT combined with IGRT markedly decreases acute and late rectal toxicity. Performing combined IMRT and IGRT can thus be envisaged for dose escalation and moderate hypofractionation. Our nomogram predicts the 3-year rectal toxicity risk by integrating total dose, fraction dose, and RT technique.

    Four patients, aged 54-84 years, presenting with life-threatening rectal bleeding from the superior hemorrhoidal artery, underwent percutaneous fibered platinum coil embolization via coaxial catheters. Pre-procedure sigmoidoscopy had failed to identify the source of hemorrhage, because the rectum was filled with fresh blood. Embolization was technically and clinically successful in all four patients. Subsequent sigmoidoscopy confirmed the diagnoses in three patients as a solitary rectal ulcer, iatrogenic traumatic ulceration following manual evacuation, and a rectal Dieulafoy's lesion. The other case was angiographically seen to be due to a rectal angiodysplasia. Embolization is an effective procedure in life-threatening superior hemorrhoidal arterial bleeding when endoscopic treatment fails, and should be preferred to rectosigmoid resection

    The goal of radiotherapy is to deliver maximal dose to the tumor and minimal dose to the surrounding tissue. This requires accurate target definition. In sites were the tumor is difficult to see on the CT images, such as for rectal cancer, PET-CT imaging can be used to better define the target. If the information from multiple PETCT images with different tracers needs to be combined, a nonrigid registration is indispensable to compensate for rectal tissue deformations. Such registration is complicated by the presence of different volumes of bowel gas in the images to be registered. In this paper, we evaluate the performance of different nonrigid registration approaches by looking at the overlap of manually delineated rectum contours after registration. Using a B-spline transformation model, the results for two similarity measures, sum of squared differences and mutual information, either calculated over the entire image or on a region of interest are compared. Finally, we also assess the effect of the registration direction. We show that the combination of MI with a region of interest is best able to cope with residual rectal contrast and differences in bowel filling. We also show that for optimal performance the registration direction should be chosen depending on the difference in bowel filling in the images to be registered.

    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) uclers 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.

    Regional lymph nodes of the rectum are not demonstrable by pedal lymphoscintigraphy. The authors have evaluated the technique of rectal lymphoscintigraphy, using a technique similar to that which has been used in the assessment of lymph nodes in breast and prostatic cancer. Thirty-five patients were studied: ten normal subjects and 25 patients with rectal cancer. In normal subjects, the lymph nodes accompanying the superior hemorrhoidal artery and the inferior mesenteric artery are demonstrable in succession; after three hours the aortic lymph nodes are demonstrable. The 25 patients with rectal cancer underwent resection of their primary tumor and the stage was defined according to Dukes (1932). In five patients (stage A) no alteration was demonstrable. In 11 patients (stage B) the demonstration of regional lymph nodes was delayed vs. the control group. In nine cases (stage C) the demonstration of regional lymph nodes was delayed and defective versus the control group

    Full Text Available Duplications of the alimentary tract are of a great rarity, particularly so in the rectum. Because of its rarity, the difficulty of making a correct diagnosis and of selection of proper approach for treatment, this entity bears a special significance. The present case report deals with a female newborn who presented with imperforate anus and a rectovestibular fistula and a mass prolapsing at the introitus. Complete excision of the mass was carried out through the perineal approach and the child then underwent, a PSARP for the correction of the rectal anomaly. Histology confirmed the mass to be a rectal duplication.

    Intestinal duplications are rare developmental anomalies that can occur anywhere along the gastrointestinal tract. Rectal duplication cysts account for approximately 4% of all duplication cysts. They usually present in childhood with symptoms of mass effect, local infection or more rarely with rectal bleeding from ectopic gastric mucosa. A 26year old male presented with a history of bright red blood per rectum. On examination a mucosal defect with an associated cavity adjacent to the rectum was identified. This was confirmed with rigid proctoscopy and CT scan imaging. A complete transanal excision was performed. Rectal duplication cysts are more common in pediatric patients. They more frequently present with symptoms of mass effect or local infection than with rectal bleeding. In adult patients they are a rare cause of rectal bleeding. Definitive treatment is with surgical excision. A transanal, transcoccygeal, posterior sagittal or a combined abdominoperineal approach may be used depending on anatomic characteristics of the duplication cyst. We present a rare case of a rectal duplication cyst presenting in adulthood with rectal bleeding, managed with transanal excision. Published by Elsevier Ltd.

    Patient: Female, 66 Final Diagnosis: Calciphylaxis Symptoms: Gastrointesinal haemorrhage Medication: None Clinical Procedure: Hemodialysis • blood transfusions Specialty: Gastroenterology and Hepatology Objective: Rare disease 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. PMID:26572938

    Examination of reliability and validity of a specialized health-related quality of life questionnaire for rectal cancer (RC) survivors (≥5 years post-diagnosis). We mailed 1,063 Kaiser Permanente (KP) RC survivors (313 ostomy and 750 anastomosis) a questionnaire containing the Modified City of Hope Quality of Life-Ostomy (mCOH-QOL-O), SF-12v2, Duke-UNC Functional Social Support Questionnaire (FSSQ), and Memorial Sloan-Kettering Cancer Center Bowel Function Index (BFI). We adapted certain BFI items for use by subjects with intestinal ostomies. We evaluated reliability for all instruments with inter-item correlations and Cronbach's alpha. We assessed construct validity only for the BFI in the ostomy group, because such use has not been reported. The overall response rate was 60.5 % (577 respondents/953 eligible). Compared with non-responders, participants were on average 2 years younger and more likely non-Hispanic white, resided in educationally non-deprived areas, and had KP membership through a group. The mCOH-QOL-O, SF-12, and FSSQ were found to be highly reliable for RC survivors. In the ostomy group, BFI Urgency/Soilage and Dietary subscales were found to be reliable, but Frequency was not. Factor analysis supported the construct of Urgency/Soilage and Dietary subscales in the ostomy group, although one item had a moderate correlation with all three factors. The BFI also demonstrated good concurrent validity with other instruments in the ostomy group. With possible exception of the BFI Frequency subscale in populations with ostomies, components of our survey can be used for the entire population of RC survivors, no matter whether they received anastomosis or ostomy.

    Purpose: To review the available literature on tumor size/volume measurements on magnetic resonance imaging for response assessment after chemoradiotherapy, and validate these cut-offs in an independent multicenter patient cohort. Methods and Materials: The study included 2 parts. (1) Review of the literature: articles were included that assessed the accuracy of tumor size/volume measurements on magnetic resonance imaging for tumor response assessment. Size/volume cut-offs were extracted; (2) Multicenter validation: extracted cut-offs from the literature were tested in a multicenter cohort (n=146). Accuracies were calculated and compared with reported results from the literature. Results: The review included 14 articles, in which 3 different measurement methods were assessed: (1) tumor length; (2) 3-dimensonial tumor size; and (3) whole volume. Study outcomes consisted of (1) complete response (ypT0) versus residual tumor; (2) tumor regression grade 1 to 2 versus 3 to 5; and (3) T-downstaging (ypTvalidation of the whole-volume measurements, in particular for the outcome ypT0 (accuracy 44%-80%), with the optimal cut-offs being 1.6 cm{sup 3} (after chemoradiation therapy) and a volume reduction of Δ80% to 86.6%. Accuracies for whole-volume measurements to assess tumor regression grade 1 to 2 were 52% to 61%, and for T-downstaging 51% to 57%. Overall accuracies for tumor length ranged between 48% and 53% and for 3D size measurement between 52% and 56%. Conclusions: Magnetic resonance volumetry using whole-tumor volume measurements can be helpful in rectal cancer response assessment with selected cut-off values. Measurements of tumor length or 3-dimensional tumor size are not helpful. Magnetic resonance volumetry is mainly accurate to assess a complete tumor response (ypT0) after chemoradiation therapy (accuracies up to 80%).

    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. This study aims to validate the diagnostic value of these volume thresholds in a larger, independent, and bi-institutional patient cohort. A total of 112 patients with locally advanced rectal cancer (2 centers) treated with a long course of CRT were enrolled. Patients underwent standard T2W-magnetic resonance imaging and DWI, both pre- and post-CRT. Two experienced readers independently determined pre-CRT and post-CRT tumor volumes (cm) on T2W-magnetic resonance image and diffusion-weighted magnetic resonance image by means of freehand tumor delineation. Tumor volume reduction rates (Δvolume) were calculated. Previously determined T2W and DWI threshold values for prevolume, postvolume, and Δvolume were tested to "prospectively" assess their respective diagnostic value in discriminating patients with a complete tumor response from patients with residual tumor. Twenty patients had a complete response. Using the average measurements between the 2 readers, areas under the curve for the pre-/post-/Δvolumes was 0.73/0.82/0.78 for T2W-magnetic resonance imaging and 0.77/0.92/0.86 for DWI, respectively. For T2W-volumetry, sensitivity and specificity using the predefined volume thresholds were 55% and 74% for pre-, 60% and 89% for post-, and 60% and 86% for Δvolume. For DWI volumetry, sensitivity and specificity were 65% and 76% for pre-, 70% and 98% for post-, and 70% and 93% for Δvolume. Previously established DWI volume thresholds can be reproduced with good results. Post-CRT DWI volumetry offers the best results for the detection of patients with a complete response after CRT with an area under the curve of 0.92, sensitivity of 70%, and specificity of 98%.

    The efficacy of response to preoperative chemoradiotherapy (CRT) in recurrent versus primary rectal cancer has not been investigated. We compared radiological downsizing between primary and recurrent rectal cancers following CRT and determined the optimal size reduction threshold for response validated by survival outcomes. The proportional change in tumor length for primary and recurrent rectal cancers following CRT was compared using the independent sample t-test. Overall survival (OS) was calculated using the Kaplan–Meier product limit method and differences between survival for tumor size reduction thresholds of 30% (response evaluation criteria in solid tumors [RECIST]), 40%, and 50% after CRT in primary and recurrent rectal cancer groups. A total of 385 patients undergoing CRT were analyzed, 99 with recurrent rectal cancer and 286 with primary rectal cancer. The mean proportional reduction in maximum craniocaudal length was significantly higher for primary rectal tumors (33%) compared with recurrent rectal cancer (11%) (P < 0.01). There was no difference in OS for either primary or recurrent rectal cancer when ≤30% or ≤40% definitions were used. However, for both primary and recurrent tumors, significant differences in median 3-year OS were observed when a RECIST cut-off of 50% was used. OS was 99% versus 77% in primary and 100% versus 42% in recurrent rectal cancer (P = 0.002 and P = 0.03, respectively). Only patients that demonstrated >50% size reduction showed a survival benefit. Recurrent rectal cancer appears radioresistant compared with primary tumors for tumor size after CRT. Further investigation into improving/intensifying chemotherapy and radiotherapy for locally recurrent rectal cancer is justified

    Perimesencephalic hemorrhage (PMH) is a type of subarachnoid hemorrhage with excellent long-term outcomes. Only 1 well-documented case of in-hospital rebleeding after PMH is described in the literature, which occurred after initiating antithrombotic treatment because of myocardial ischemia. We describe a patient with PMH without antithrombotic treatment who had 2 episodes of recurrent bleeding on the day of ictus. To validate the radiologic findings, we conducted a case-control study. Six neuroradiologists and 2 neuroradiology fellows performed a blinded assessment of serial unenhanced head computed tomography (CT) scans of 8 patients with a perimesencephalic bleeding pattern (1 index patient, 6 patients with PMH, 1 patient with 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 2 episodes after the onset headache with a sudden increase of the headache. Blinded assessment of serial head CT scans of 8 patients with a perimesencephalic bleeding pattern identified the patient who was clinically suspected to have 2 episodes of recurrent bleeding to have an increased amount of subarachnoid blood on 2 subsequent CT scans. Recurrent bleeding after PMH may also occur in patients not treated with antithrombotics. Even after early rebleeding, the prognosis of PMH is excellent. Copyright © 2017 Elsevier Inc.

    To report a case of rectal duplication in the adult and make a literature review. The intestinal duplications are injuries of congenital origin that can exist from the base of the tongue to the anal verge, being the most frequent site at level of terminal ileum (22%) and at the rectal level in 5% To date approximately exist 80 reports in world-wide Literature generally in the pediatric population being little frequent in the adult age. Its presentation could be tubular or cystic. The recommended treatment is the surgical resection generally in block with coloanal anastomosis. A case review of rectal duplication in the adult and the conducted treatment. The case of a patient appears with diagnose of rectal duplication with tubular type,whose main symptom was constipation and fecal impactation. In the exploration was detect double rectal lumen (anterior and posterior) that it above initiates by of the anorectal ring with fibrous ulcer of fibrinoid aspect of 3 approx cm of length x 1 cm wide, at level of the septum that separates both rectal lumina. The rectal duplication is a rare pathology in the adult nevertheless is due to suspect before the existence of alterations in the mechanics of the defecation, rectal prolapse and rectal bleeding,the election treatment is a protectomy with colonic pouch in "J" and coloanal anastomosis.

  2. Impact of dose-distribution uncertainties on rectal ntcp modeling I: Uncertainty estimates

    2001-01-01

    A trial of nonescalated conformal versus conventional radiotherapy treatment of prostate cancer has been carried out at the Royal Marsden NHS Trust (RMH) and Institute of Cancer Research (ICR), demonstrating a significant reduction in the rate of rectal bleeding reported for patients treated using the conformal technique. The relationship between planned rectal dose-distributions and incidences of bleeding has been analyzed, showing that the rate of bleeding falls significantly as the extent of the rectal wall receiving a planned dose-level of more than 57 Gy is reduced. Dose-distributions delivered to the rectal wall over the course of radiotherapy treatment inevitably differ from planned distributions, due to sources of uncertainty such as patient setup error, rectal wall movement and variation in the absolute rectal wall surface area. In this paper estimates of the differences between planned and treated rectal dose-distribution parameters are obtained for the RMH/ICR nonescalated conformal technique, working from a distribution of setup errors observed during the RMH/ICR trial, movement data supplied by Lebesque and colleagues derived from repeat CT scans, and estimates of rectal circumference variations extracted from the literature. Setup errors and wall movement are found to cause only limited systematic differences between mean treated and planned rectal dose-distribution parameter values, but introduce considerable uncertainties into the treated values of some dose-distribution parameters: setup errors lead to 22% and 9% relative uncertainties in the highly dosed fraction of the rectal wall and the wall average dose, respectively, with wall movement leading to 21% and 9% relative uncertainties. Estimates obtained from the literature of the uncertainty in the absolute surface area of the distensible rectal wall are of the order of 13%-18%. In a subsequent paper the impact of these uncertainties on analyses of the relationship between incidences of bleeding

    Severe bleeding accounts for about one-third of in-hospital trauma deaths. Patients with a high baseline risk of death have the most to gain from the use of life-saving treatments. An accurate and user-friendly prognostic model to predict mortality in bleeding trauma patients could assist doctors and paramedics in pre-hospital triage and could shorten the time to diagnostic and life-saving procedures such as surgery and tranexamic acid (TXA). The aim of the study was to develop and validate a prognostic model for early mortality in patients with traumatic bleeding and to examine whether or not the effect of TXA on the risk of death and thrombotic events in bleeding adult trauma patients varies according to baseline risk. Multivariable logistic regression and risk-stratified analysis of a large international cohort of trauma patients. Two hundred and seventy-four hospitals in 40 high-, medium- and low-income countries. We derived prognostic models in a large placebo-controlled trial of the effects of early administration of a short course of TXA [Clinical Randomisation of an Antifibrinolytic in Significant Haemorrhage (CRASH-2) trial]. The trial included 20,127 trauma patients with, or at risk of, significant bleeding, within 8 hours of injury. We externally validated the model on 14,220 selected trauma patients from the Trauma Audit and Research Network (TARN), which included mainly patients from the UK. We examined the effect of TXA on all-cause mortality, death due to bleeding and thrombotic events (fatal and non-fatal myocardial infarction, stroke, deep-vein thrombosis and pulmonary embolism) within risk strata in the CRASH-2 trial data set and we estimated the proportion of premature deaths averted by applying the odds ratio (OR) from the CRASH-2 trial to each of the risk strata in TARN. For the stratified analysis according baseline risk we considered the intervention TXA (1 g over 10 minutes followed by 1 g over 8 hours) or matching placebo. For the

    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.

    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.

    We report the case of a 17-year-old male admitted to our academic hospital with massive rectal bleeding. Since childhood he had reported recurrent gastrointestinal bleeding and had two exploratory laparotomies 5 and 2 years previously. An emergency abdominal computed tomography scan, gastroscopy and colonoscopy, performed after hemodynamic stabilization, were considered normal. High-dose intravenous proton pump inhibitor (PPI) therapy was initiated and bleeding stopped spontaneously. Two other massive rectal bleeds occurred 8 h after each cessation of PPI which led to a hemostatic laparotomy after negative gastroscopy and small bowel capsule endoscopy. This showed long tubular duplication of the right colon, with fresh blood in the duplicated colon. Obscure lower gastrointestinal bleeding is a difficult medical situation and potentially life-threatening. The presence of ulcerated ectopic gastric mucosa in the colonic duplication explains the partial efficacy of PPI therapy. Obscure gastrointestinal bleeding responding to empiric anti-acid therapy should probably evoke the diagnosis of bleeding ectopic gastric mucosa such as Meckel's diverticulum or gastrointestinal duplication, and gastroenterologists should be aware of this potential medical situation.

    Hemorrhoids usually do not pose diagnostic difficulties and they rarely cause massive bleeding. We report a case of massive rectal bleeding over 18 h needing 22 U blood transfusion treated by superselective transcatheter coil embolization 12 h following operative treatment performed in a different hospital. Diagnostic angiography with a view to superselective embolization, following failure of sigmoidoscopy to localize and treat the cause of hemorrhage, might act as a life-saving treatment in massive rectal bleeding, obviating the need for repeated endoscopy or emergency surgery

    At present, none of the conventional surgical treatments of solitary rectal ulcer associated with internal rectal prolapse seems to be satisfactory because of the high incidence of recurrence. The stapled transanal rectal resection has been demonstrated to successfully cure patients with internal rectal prolapse associated with rectocele, or prolapsed hemorrhoids. This prospective study was designed to evaluate the short-term and long-term results of stapled transanal rectal resection in patients affected by solitary rectal ulcer associated with internal rectal prolapse and nonresponders to biofeedback therapy. Fourteen patients were selected on the basis of validated constipation and continence scorings, clinical examination, anorectal manometry, defecography, and colonoscopy and were submitted to biofeedback therapy. Ten nonresponders were operated on and followed up with incidence of failure, defined as no improvement of symptoms and/or recurrence of rectal ulceration, as the primary outcome measure. Operative time, hospital stay, postoperative pain, time to return to normal activity, overall patient satisfaction index, and presence of residual rectal prolapse also were evaluated. At a mean follow-up of 27.2 (range, 24-34) months, symptoms significantly improved, with 80 percent of excellent/good results and none of the ten operated patients showed a recurrence of rectal ulcer. Operative time, hospital stay, and time to return to normal activity were similar to those reported after stapled transanal rectal resection for obstructed defecation, whereas postoperative pain was slightly higher. One patient complained of perineal abscess, requiring surgery. The stapled transanal rectal resection is safe and effective in the cure of solitary rectal ulcer associated with internal rectal prolapse, with minimal complications and no recurrences after two years. Randomized trials with sufficient number of patients are necessary to compare the efficacy of stapled transanal

    Purpose: This analysis was performed to evaluate the results of endocavitary radiotherapy (RT) administered for early rectal cancer at our institution. Methods and Materials: Patient charts were retrospectively reviewed to determine the results of endocavitary RT regarding survival, local control, and complications. Between 1987 and 1994, 25 patients were treated with endocavitary RT for early rectal cancer. Twenty had early, low grade tumors and met the criteria for treatment with curative intent. Five had more advanced, high grade, or multiple recurrent tumors and were treated with palliative intent. The tumors were treated to between 20 and 155 Gy in one to four fractions with 50 KV x-rays given through a specialized proctoscope. Patients were followed for 5 to 84 months (median = 55 months) after therapy. Local control and survival were determined using the Kaplan-Meier method. Results: Local control was achieved in 18 of the 20 patients treated with curative intent and 4 of 5 treated with palliative intent. For those patients treated with curative intent, the 5-year local control rate was 89% and the 5-year survival rate was 76%. The most significant toxicity was ulceration that occurred in 5 of the 25 patients. The ulcers were asymptomatic in three cases and associated with bleeding in one case. The fifth patient had pain. One ulcer was biopsied, resulting in perforation that was treated with an abdominal perineal resection (APR). There was no tumor found upon pathologic evaluation. Conclusions: Endocavitary RT can be used to treat patients with early, low-grade rectal cancers and will yield a high level of disease control and a low risk of serious complications. Major advantages of this treatment technique are that it requires neither general anesthesia nor hospitalization

    Although high-dose-rate intracavitary radiotherapy (HDR ICR) has been used in the treatment of cervical cancer, the potential for increased risk of late complication, most commonly in the rectum, is a major concern. We have previously reported on 136 patients treated with HDR brachytherapy between 1995 and 1999. The purpose of this study is to upgrade the previous data and confirm the correlation between late rectal complication and rectal dose in cervix cancer patients treated with HDR ICR. A retrospective analysis was performed for 222 patients with cervix cancer who were treated for curative intent with extemal beam radiotherapy (EBRT) and HDR ICR from July 1995 to December 2001. The median dose of EBRT was 50.4 (30.6-56.4) Gy with a daily fraction size 1.8 Gy. A total of six fractions of HDR ICR were given twice weekly with fraction size of 4 (3-5.5) Gy to A point by Iridium-192 source. The rectal dose was calculated at the rectal reference point using the barium contrast criteria in vivo measurement of the rectal dose was performed with thermoluminescent dosimeter (TLD) during HDR ICR. The median follow-up period was 39 months, ranging from 6 to 90 months. Twenty-one patients (9.5%) experienced late rectal bleeding, from 3 to 44 months (median, 13 months) after the completion of RT. The calculated rectal doses were not different between the patients with rectal bleeding and those without, but the measured rectal doses were higher in the complicated patients. The differences of the measured ICR rectal fractional dose, ICR total rectal dose, and total rectal biologically equivalent dose (BED) were statistically significant. When the measured ICR total rectal dose was beyond 16 Gy, when the ratio of the measured rectal dose to A point dose was beyond 70%, or when the measured rectal BED was over 110 GY 3 , a high possibility of late rectal complication was found. Late rectal complication was closely correlated with measured rectal dose by in vivo dosimetry using

    Rectal duplication cyst is a rare congenital lesion which is known to be associated with other congenital defects, especially genitourinary and vertebral anomalies. Infections with fistulization, bleeding, and malignant degeneration are the major complications of developmental cysts. The case of an 83-year-old woman referred for acute constipation associated with abdominal distension is reported. CT and MRI showed a large cystic mass of the pelvis with extrinsic compression of the rectum. Surgical excision would have been the treatment of choice. In this case, the patient was unfortunately not eligible for surgery due to her poor general condition but responded well to conservative treatment.

    To evaluate the value of the chemical shift effect (CSE) as well as other criteria for the prediction of lymph node status. Twenty-nine patients who underwent radical surgery of rectal cancers were studied with pre- and postoperative specimen MRI. Lymph nodes were harvested from transverse whole-mount specimens and compared with in vivo and ex vivo images to obtain a precise slice-for-section match. Preoperative MR characteristics including CSE, as well as other predictors, were evaluated by two readers independently between benign and metastatic nodes. A total of 255 benign and 35 metastatic nodes were obtained; 71.4% and 69.4% of benign nodes were detected with regular CSE for two readers, whereas 80.0% and 74.3% of metastatic nodes with absence of CSE. The CSE rendered areas under the ROC curve (AUC) of 0.879 and 0.845 for predicting nodal status for two readers. The criteria of nodal location, border, signal intensity and minimum distance to the rectal wall were also useful but with AUCs (0.629-0.743) lower than those of CSE. CSE is a reliable predictor for differentiating benign from metastatic nodes. Additional criteria should be taken into account when it is difficult to determine the nodal status by using only a single predictor. (orig.)

    Ronnekleiv-Kelly, Sean M; Kennedy, Gregory D

    2011-01-01

    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. PMID:21412493

    To evaluate three different methods for controlling presacral massive bleeding during pelvic operations. Clinical data of 11 patients with presacral massive bleeding during pelvic operation at The Sixth Affiliated Hospital of Sun Yat-sen University and 157 Branch Hospital of Guangzhou General Hospital of Guangzhou Military Command from January 2001 to January 2016 were analyzed retrospectively. Hemostasis methods for presacral massive bleeding during operation included gauze packing (whole pressure), drawing pin (local pressure) and absorbable gauze (absorbable gauze was adhered to bleeding position with medical glue after local pressure). Efficacy of these 3 methods for controlling bleeding was evaluated and compared. Ten patients were male and 1 was female with average age of 65.2 (40 to 79) years old. Eight cases were rectal cancer, 2 were presacral malignancies and 1 was rectal benign lesion. Bleeding volume during operation was 300 to 2 500 (median 800) ml. From 2001 to 2012, 4 cases received gauze packing, of whom, 3 cases were scheduled Dixon resection before operation and then had to be referred to Hartman resection; 3 cases died of systemic failure due to postoperative chronic errhysis and infection, and 1 underwent re-operation. At the same time from 2001 to 2012, 5 cases received drawing pin, of whom, bleeding of 3 cases was successfully controlled and Dixon resection was completed. In other 2 cases with hemostasis failure, 1 case underwent re-operation following the use of gauze packing, and another 1 case received absorbable gauze hemostasis. All the 5 patients were healing. From 2013 to 2016, 2 cases completed scheduled anterior resection of rectum after successful hemostasis with absorbable gauze and were healing and discharged. Gauze packing hemostasis is a basic method for controlling presacral massive bleeding. Drawing pin and absorbable gauze hemostasis are more precise and may avoid the change of surgical procedure. But drawing pin has the

    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.)

    2014-03-01

    Solitary rectal ulcer syndrome (SRUS) is uncommon and its management is controversial. The aim of this study was to evaluate the outcome of patients with SRUS who underwent laparoscopic ventral rectopexy (LVR). A review was performed of a prospective database at the Oxford Pelvic Floor Centre to identify patients between 2004 and 2012 with a histological diagnosis of SRUS. All were initially treated conservatively and surgical treatment was indicated only for patients with significant symptoms after failed conservative management. The primary end-point was healing of the ulcer. Secondary end-points included changes in the Wexner Constipation Score and Faecal Incontinence Severity Index (FISI). Thirty-six patients with SRUS were identified (31 women), with a median age of 44 (15–81) years. The commonest symptoms were rectal bleeding (75%) and obstructed defaecation (64%). The underlying anatomical diagnosis was internal rectal prolapse (n = 20), external rectal prolapse (n = 14) or anismus (n = 2). Twenty-nine patients underwent LVR and one a stapled transanal rectal resection (STARR) procedure. Nine (30%) required a further operation, six required posterior STARR for persistent SRUS and two a per-anal stricturoplasty for a narrowing at the healed SRUS site. Healing of the SRU was seen in 27 (90%) of the 30 patients and was associated with significant improvements in Wexner and FISI scores at a 3-year follow-up. Almost all cases of SRUS in the present series were associated with rectal prolapse. LVR resulted in successful healing of the SRUS with good function in almost all patients, but a significant number will require further surgery such as STARR for persistent obstructed defaecation.

    2009-01-01

    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.)

    Purpose: The purpose of this paper is to use the outcome of a dose escalation protocol for three-dimensional conformal radiation therapy (3D-CRT) of prostate cancer to study the dose-response for late rectal toxicity and to identify anatomic, dosimetric, and clinical factors that correlate with late rectal bleeding in multivariate analysis. Methods and Materials: Seven hundred forty-three patients with T1c-T3 prostate cancer were treated with 3D-CRT with prescribed doses of 64.8 to 81.0 Gy. The 5-year actuarial rate of late rectal toxicity was assessed using Kaplan-Meier statistics. A retrospective dosimetric analysis was performed for patients treated to 70.2 Gy (52 patients) or 75.6 Gy (119 patients) who either exhibited late rectal bleeding (RTOG Grade 2/3) within 30 months after treatment (i.e., 70.2 Gy--13 patients, 75.6 Gy--36 patients) or were nonbleeding for at least 30 months (i.e., 70.2 Gy--39 patients, 75.6 Gy--83 patients). Univariate and multivariate logistic regression was performed to correlate late rectal bleeding with several anatomic, dosimetric, and clinical variables. Results: A dose response for ≥ Grade 2 late rectal toxicity was observed. By multivariate analysis, the following factors were significantly correlated with ≥ Grade 2 late rectal bleeding for patients prescribed 70.2 Gy: 1) enclosure of the outer rectal contour by the 50% isodose on the isocenter slice (i.e., Iso50) (p max (p max

    2015-01-01

    Rectal cancer is the second most common cancer in large intestine. The prevalence and the number of young patients diagnosed with rectal cancer have made it as one of the major health problems in the world. With regard to the improved access to and use of modern screening tools, a number of new cases are diagnosed each year. Considering the location of the rectum and its adjacent organs, management and treatment of rectal tumor is different from tumors located in other parts of the gastrointestinal tract or even the colon. In this article, we will review the current updates on rectal cancer including epidemiology, risk factors, clinical presentations, screening, and staging. Diagnostic methods and latest treatment modalities and approaches will also be discussed in detail. PMID:26034724

    This report describes the case of a 55-year-old woman with varicella-zoster virus (VZV) sacral meningoradiculitis (Elsberg syndrome) who presented with herpes zoster in the left S2 dermatome area, urinary retention, and constipation. Lumbar magnetic resonance imaging showed the left sacral nerve root swelling with enhancement. Thereafter, she suddenly showed massive hematochezia and hemorrhagic shock because of a rectal ulcer. To elucidate the relation between Elsberg syndrome and rectal ulcer, accumulation of similar cases is necessary. To avoid severe complications, attention must be devoted to the possibility of rectal bleeding in the early stage of Elsberg syndrome.

    Purpose: To compare the single-fraction dose-related incidence of rectal obstruction and/or bleeding in normothermic and hypothermic rectums of a rat model. Methods and Materials: A 1.9-cm length of rectum was irradiated with a single fraction in 57 Sprague-Dawley rats using a dedicated image-guided small animal irradiator and Monte Carlo–based treatment planning system. All rats had a rectal temperature control apparatus placed during irradiation and were stratified to achieve either a normothermic (37°C) or hypothermic (15°C) rectal wall temperature. Radiation was delivered to a 1-cm-diameter cylindrical volume about the cooling device and rectal wall. The radiation dose was escalated from 16 Gy up to 37 Gy to assess the dose response in each arm. The primary endpoint of this study was rectal obstruction and/or bleeding during a follow-up of 180 to 186 days. Histologic scoring was performed on all study rats. Results: Probit analysis showed a dose associated with a 50% incidence of rectal obstruction of 24.6 Gy and 40.8 Gy for normothermic and hypothermic arms, respectively. The occurrence of obstruction and/or bleeding correlated with the posttreatment histologic score for normothermic rats; however, there was no difference in histologic score between normothermic and hypothermic rats at the highest dose levels evaluated. Conclusions: A significant radioprotective effect was observed using local hypothermia during a single large dose of radiation for the functional endpoint of rectal obstruction and/or bleeding. A confirmatory study in a large animal model with anatomic and physiologic similarities to humans is suggested.

    Intestinal duplications are uncommon but recognised developmental anomalies. Duplications of the rectum are the most uncommon of these anomalies. They may present with perianal fistulae, bleeding, a pelvic mass or symptoms produced by a mass, or, rarely, malignant change. We present a case of an adenocarcinoma within a rectal duplication cyst which was initially thought to be inoperable but was treated by radical surgery.

  10. Bayesian network modelling of upper gastrointestinal bleeding

    2013-09-01

    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.

  11. Solitary Rectal Ulcer Syndrome: A Biopsychosocial Assessment

    Directory of Open Access Journals (Sweden)

    Hamed Daghaghzadeh

    2016-06-01

    Full Text Available Background: Solitary rectal ulcer syndrome (SRUS is a chronic disorder of the gastrointestinal tract and its etiology is not well understood. There is no specific treatment for this syndrome and patients with SRUS may, for years, experience many complications. The aim of the present research was the biopsychosocial study of patients with SRUS.Methods: The study participants consisted of 16 patients with SRUS (7 men and 9 women. Their medical records were reviewed retrospectively to evaluate the clinical spectrum of the patients along with the endoscopic and histological findings. Moreover, psychiatric and personality disorders [based on Diagnostic and Statistical Manual of Mental Disorders, 4th ed, Text Revision (DSM IV-TR], psychosocial stressors, early life traumas, and coping mechanisms were assessed through structured interviews.Results: At presentation, mean age of the patients was 39 years (16 to 70. Common symptoms reported included rectal bleeding (93.8%, rectal self-digitations (81.2%, passage of mucous (75%, anal pain (75%, and straining (75%. Endoscopically, solitary and multiple lesions were present in 9 (60% and 4 (26.7% patients, respectively, and 87% of lesions were ulcerative and 13.3% polypoidal. The most common histological findings were superficial ulceration (92.85% and intercryptic fibromuscular obliteration (87.71%. Common psychosocial findings included anxiety disorders (50%, depression (37.5%, obsessive-compulsive personality disorder (OCPD or traits (62.5%, interpersonal problems (43.75%, marital conflicts (43.75%, occupational stress (37.5%, early life traumas, physical abuse (31.25%, sexual abuse (31.25%, dysfunctional coping mechanisms, emotional inhibition (50%, and non-assertiveness (37.5%.Conclusion: Given the evidence in this study, we cannot ignore the psychosocial problems of patients with SRUS and biopsychosocial assessment of SRUS is more appropriate than biomedical evaluation alone.

    2008-01-01

    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

  16. Rectal dose during radiotherapy: how much is too much?

    International Nuclear Information System (INIS)

    Booth, J.; Adelaide University,

    2002-01-01

    Full text: The clinical intent of radiotherapy for prostate cancer is to deposit high radiation dose to the prostate and as low as possible to healthy tissue. The rectum is one adjacent structure that is very sensitive to side effects including rectal bleeding, stricture, and ulceration. The dose that the rectum receives is often difficult to predict because its position and size will differ on each treatment day from the original planning CT images. The aim of this work is to use current measured values from the literature on rectal wall motion to mathematically model the dynamic rectal wall. The model is used with a pre calculated dose distribution to evaluate the difference between planned anticipated and actually delivered rectal radiation doses. The dose delivered will depend on the status of the rectum in the preliminary planning CT scan. Deviations from the planned dose were larger if the rectum was empty in the planning CT scan (ΔD = ± 25%) than if it was full (ΔD = ± 15%). If the planning CT scan demonstrated the rectum in the mean treatment position the dose variation is reduced (ΔD = ± 10%). These results support the conclusion that care should be taken to plan treatments using CT images that contain reproducible information

    Solitary rectal ulcer syndrome (SRUS) is a rare disorder often misdiagnosed as a malignant ulcer. Histopathological features of SRUS are characteristic and pathognomonic; nevertheless, the endoscopic and clinical presentations may be confusing. The aim of the present study was to assess the clinical findings, surgical treatment, and outcomes in patients who suffer from SRUS. A retrospective chart review was undertaken, from January 1989 to May 2005 for all patients who were diagnosed with SRUS. Data recorded included: patient's age, gender, clinical presentation, past surgical history, diagnostic and preoperative workup, operative procedure, complications, and outcomes. During the study period, 23 patients were diagnosed with SRUS. Seven patients received only medical treatment, and in three patients, the ulcer healed after medical treatment. Sixteen patients underwent surgical treatment. In four patients, the symptoms persisted after surgery. Two patients presented with postoperative rectal bleeding requiring surgical intervention. Three patients developed late postoperative sexual dysfunction. One patient continued suffering from rectal pain after a colostomy was constructed. Median follow-up was 14 (range 2-84) months. The results of this study show clearly that every patient with SRUS must be assessed individually. Initial treatment should include conservative measures. In patients with refractory symptoms, surgical treatment should be considered. Results of anterior resection and protocolectomy are satisfactory for solitary rectal ulcer.

    2011-03-01

    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.

    To assess the effect of a shrinking rectal balloon implant (RBI) on the anorectal dose and complication risk during the course of moderately hypofractionated prostate radiotherapy. In 15 patients with localized prostate cancer, an RBI was implanted. A weekly kilovolt cone-beam computed tomography (CBCT) scan was acquired to measure the dynamics of RBI volume and prostate-rectum separation. The absolute anorectal volume encompassed by the 2 Gy equieffective 75 Gy isodose (V 75Gy ) was recalculated as well as the mean anorectal dose. The increase in estimated risk of grade 2-3 late rectal bleeding (LRB) between the start and end of treatment was predicted using nomograms. The observed acute and late toxicities were evaluated. A significant shrinkage of RBI volumes was observed, with an average volume of 70.4% of baseline at the end of the treatment. Although the prostate-rectum separation significantly decreased over time, it remained at least 1 cm. No significant increase in V 75Gy of the anorectum was observed, except in one patient whose RBI had completely deflated in the third week of treatment. No correlation between mean anorectal dose and balloon deflation was found. The increase in predicted LRB risk was not significant, except in the one patient whose RBI completely deflated. The observed toxicities confirmed these findings. Despite significant decrease in RBI volume the high-dose rectal volume and the predicted LRB risk were unaffected due to a persistent spacing between the prostate and the anterior rectal wall.

    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.

    The human pinworm Enterobius vermicularis is normally found within the human gastrointestinal tract. Pregnant females migrate out of their host's anus at night to lay their eggs perianally. As a consequence of this nocturnal migration some worms find their way into adjacent orifices, most commonly the female genitourinary tract, producing irritative symptoms such as vulvovaginitis. A case of pinworm infestation of the uterus presented as postmenopausal bleeding.

    Gastrointestinal bleeding remains a major diagnostic problem. Although advances have been made in the medical and surgical methods of managing gastrointestinal bleeding, the commonly employed techniques of barium radiography, endoscopy, and angiography may not successfully localize the site and define the cause of gastrointestinal bleeding. Two widely available technetium-99m-labeled radiopharmaceuticals, sulfur colloid and red blood cells are currently used in the evaluation of patients who are bleeding from the gastrointestinal tract. Surgically confirmed 19 patients with use of 99m Tc-sulfur colloid (7 cases) and 99m Tc-RBC (12 cases) were retrospectively evaluated. The overall sensitivity of scintigraphy in detection of bleeding and localization of bleeding site was 68% and 84%, respectively. The authors conclude that bleeding scintigraphy is a safe, sensitive, and non-invasive method as an effective screening test before performing angiography or surgery.

    Purpose: As transperineal interstitial permanent prostate brachytherapy (TIPPB) grows in acceptance as an option in the treatment of organ-confined prostate cancer, its associated toxicities are being defined. This clinical report documents rectal toxicity from a large cohort of men treated by a single practitioner for adenocarcinoma of the prostate. Methods and Materials: Eight hundred twenty-five men were treated from September 1992 to September 1998 with TIPPB. One hundred-forty were treated in conjunction with external beam irradiation (EBRT) and 685 with TIPPB alone. All patients were implanted under real-time ultrasound guidance. No dose-volume histogram analysis was performed for this study. All patients were followed at 5 weeks after the procedure, then every 3-6 months thereafter. Rectal morbidity was graded by a modified RTOG toxicity scale. Therapy to control symptoms was recommended on an individual basis. Results: The median follow-up for the cohort is 48 months. A total of 77 patients (9.4%) reported Grade 1 toxicity at some time following an implant whereas 54 patients (6.6%) reported Grade 2 toxicity. The peak post-TIPPB time for experiencing rectal toxicity was 8 months at which time Grade 1 and 2 rectal toxicity was reported in 9.5% of the patients. This improved over the subsequent months and resolved in all patients by 3((1)/(2)) years. Four patients (0.5%) reported Grade 3 rectal toxicity with rectal ulceration identified on colonoscopy at 1 year from implant. Two of the four patients had colonic manipulation in the radiated portion of the colon which subsequently caused it to bleed. None of the patients required blood product transfusion. In 3 of the 4 patients the Grade 3 rectal toxicity has resolved spontaneously and 1 patient continues to heal at the time of this report. No patient required hospitalization or surgical intervention. Conclusion: TIPPB is a tolerable and acceptable treatment option when used alone in early-stage, organ

    Metastases to the breast from extramammary neoplasms are very rare, constituting 2.7% of all malignant breast tumours. The most common primary tumor metastatic to the breast is primary breast cancer. Rectal cancer metastasizing to the breast is extremely rare. We report a case of aggressive rectal carcinoma with metastasis to the breast.

    The low rectal cancers are treated by anorectal amputation and pose the problem of the sphincter conservation. Some authors extend the clinical definition to developed injuries until 12 cm from the anal margin. The rectal cancer is a frequent tumour which remains serious. When the tumour is low, the treatment consists in an anorectal amputation with a permanent colostomy. The radical non preserving surgery is the usual treatment of these injuries. Until 1960 the rectal adenocarcinoma was considered as a radioresistant tumour because of the impossibility to deliver an enough dose to the tumour by external radiotherapy. But other studies showed that those lesions were radiosensitive and often radiocurable. The medical treatments haven't yet demonstrated their efficiency in the treatment of the rectal cancer. We'll study the radiotherapy in the treatment of the low rectal cancer, solely radiotherapy, radiosurgical associations. 32 refs., 5 tabs

    To evaluate whether ultrasound-guided compression performed immediately after transrectal ultrasound (TRUS)-guided prostate biopsy decreases bleeding complications. We prospectively evaluated a total of 148 consecutive patients who underwent TRUS-guided prostate biopsy between March 2015 and July 2016. Systematic 12-core prostate biopsy was performed in all patients. Of these, 100 patients were randomly assigned to one of two groups: the compression group (n = 50) underwent TRUS-guided compression on bleeding biopsy tracts immediately after prostate biopsy, while the non-compression group (n = 50) underwent TRUS-guided prostate biopsy alone. The incidence rate and duration of hematuria, hematospermia, and rectal bleeding were compared between the two groups. The incidence rates of hematuria and hematospermia were not significantly different between the two groups (60 vs. 64%, p = 0.68; 22 vs. 30%, p = 0.362, respectively, for compression vs. non-compression group). The rectal bleeding incidence was significantly lower in the compression group as compared to the non-compression group (20 vs. 44%, p = 0.01). However, there were no significant differences in the median duration of hematuria, hematospermia, or rectal bleeding between the two groups (2, 8, and 2 days vs. 2, 10, and 1 days, p > 0.05, respectively, for compression vs. non-compression group). TRUS-guided compression [p = 0.004, odds ratio (OR) 0.25] and patient age (p = 0.013, OR 0.93) were significantly protective against the occurrence of rectal bleeding after prostate biopsy in multivariable analysis. Although it has no impact on other complications, ultrasound-guided compression on bleeding biopsy tracts performed immediately after TRUS-guided prostate biopsy is an effective and practical method to treat or decrease rectal bleeding.

    Rectal malignant melanoma originates in the melanocytes of the anorectal area. Represent less than 1 % of all melanomas, and 4 % of all malignant tumors of the rectum and anus. The most common clinical manifestation is bleeding, the clinical examination may be mistaken for benign lesions or hemorrhoids. Given the rarity of the diagnosis are not well-defined therapeutic procedures. Prognosis for patient is poor. The authors present a case of 70-year old patient with rectal melanoma diagnosed at an advanced stage of disease, initially with diagnosis a thrombotic hemorrhoid. (author)

    PURPOSE: To determine the risk of urinary incontinence or severe rectal complications in patients who have TURP/TUIP or rectal bleeding after I-125 prostate brachytherapy. MATERIAL AND METHODS: One hundred nine patients with T1-T2 prostatic carcinoma were treated with I-125 implantation from 1988 through 1994. Ten patients underwent TURP/TUIP after brachtherapy to relieve urinary obstruction refractory to non-surgical management. Twenty-two developed rectal morbidity and were subsequently followed with endoscopy and serial clinical evaluation. RESULTS: Permanent urinary incontinence following TURP/TUIP developed in seven of 10 patients. Urinary incontinence was mild in three patients (LENT score = 1) and severe in 4 additional patients (LENT score = 3). There was no relationship between the degree of incontinence and the use of TURP versus TUIP, mass of tissue resected, or time between brachytherapy and TURP/TUIP. Urethral doses were higher than we generally recommend (> 140 Gy) in the 5 patients for whom detailed urethral radiation dose information was available, Rectal morbidity developed in twenty-two patients. Twenty experienced radiation proctitis-related bright red blood per rectum (BRBPR), the majority of which ((15(20))) were mild (RTOG score = 1) and treated with medical management. The other 5 developed either a rectal ulcer ((3(5))) or fistula ((2(5))). The two patients without significant BRBPR developed a fistula and ulcer. Two of three patients with fistulas had predisposing conditions (pre-implant history of fistula and previous pelvic radiation for rectal cancer). All four rectal ulcers healed with conservative management. CONCLUSION: Permanent urinary incontinence is common in patients who require a TURP/TUIP after prostate brachytherapy. Its cause is multifactorial and may include surgically-related damage to the urinary sphincters and radiation dose to the uretha. Rectal morbidity after prostate brachtherapy is mild in the majority of cases and

    Variceal bleeding is a serious complication in patients with cirrhosis. Among the criteria that were proposed in Baveno conferences, the Adjusted Blood Requirement Index (ABRI) has not been validated prospectively in clinical practice. We therefore aim to evaluate the measurement of ABRI as a marker of failure to control bleeding and to evaluate the consistency of ABRI in relation to other criteria of failure to control variceal bleeding. All patients with variceal bleeding who presented to Aga Khan University Hospital from January 2010 to December 2012 who were administered transfusion of packed red blood cells were included after obtaining informed consent. All patients were managed as per the standard protocol with intravenous terlipressin along with band ligation and injection of cyanoacrylate in cases of esophageal and fundal varices, respectively. Hemoglobin and hematocrit were measured every 6 h for 48 h and then every 12 h until 5 days of index bleed in each patient. Packed cells were transfused if hemoglobin decreased below 8 g/dl. The number of blood units transfused, change in hemoglobin values, and ABRI were calculated after each unit of blood transfusion till 120 h. In patients in whom bleed could not be controlled, an ABRI value of 0.75 or more was compared with other Baveno IV-based parameters that define failure to control variceal bleeding. During the study period, 137 eligible patients with variceal bleed were admitted. The mean age of the patients was 52±12 years. The majority of patients (50.4%) were in Child-Pugh class B, followed by 38% in Child-Pugh class C. According to the Baveno IV criteria, overall failure to control acute variceal bleeding occurred in 52 (37.9%) patients. Excluding ABRI, failure to control bleeding was found in 22/137 (16%) patients, whereas ABRI-based criteria showed that in 34/137 (24.8%) patients, bleeding could not be controlled. There were only four (2.9%) patients with variceal bleeding in whom ABRI and

    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.

    The aim of this study was to investigate the predictive impact of polymorphisms in the HIF-1α gene on the response to chemoradiotherapy (CRT) in rectal cancer. This study included two cohorts of patients with locally advanced rectal cancer receiving long-course CRT. The HIF-1α C1772T (rs11549465...... tumour response (P=0.03) in the validation cohort. In conclusion, these results suggest that HIF-1α polymorphisms have no value as predictors of response to neoadjuvant CRT in rectal cancer. The results of the HIF-1α c(*)191T>C in two cohorts differ and emphasise the importance of biomarker validation....

    Rectal duplications represent 5% of all duplications in the alimentary tract, and they are very rarely diagnosed during the neonatal period. The authors present the method of investigation and the results of surgical treatment of a full-term neonate with a sciatic hernia containing a rectal duplication. The procedure started with three-port laparoscopy, but excision of the tubular duplication of the rectum was possible only by a transanal endorectal pull-through approach. The sciatic hernia was closed, and plastic sutures on the buttock finished the procedure. The coincidence of sciatic hernia with rectal duplication is extremely rare, and the method of treatment depends exclusively on the anatomical conditions.

    To analyze high risk factors of postoperative upper gastrointestinal (GI) bleeding after neurosurgery so as to give guidance for prevention of GI bleeding. A questionnaire was developed to investigate the medical records of 1500 patients who were hospitalized and underwent neurosurgical operations in 1997. Logistic regression analysis was made. 1430 valid questionnaires were obtained. Postoperative upper GI bleeding occurred in 75 patients (5.24%). The incidence of upper GI bleeding were 6.64% (54/813) in the male patients and 3.40% (21/617) in the female persons (P = 0.007); 9.88% (41/415) in those aged > 50 and 3.35% in those aged hematoma, intraventricular hemorrhage, subdural hematoma, and extradural hematoma were 15.7%, 10.0%, 6.00%, and 2.94% respectively (P = 0.02). The incidence of upper GI bleeding of the patients with tumors of fourth ventricle of cerebrum, brainstem, cerebral hemisphere, and sellar hypothalamus were 15.79% (3/19), 7.89%, 5.71%, and 3.74% respectively. In the emergent cases, the incidence of upper GI bleeding was higher in those with hypertension. The incidence of upper GI bleeding was 5.46% in the patients undergoing adrenocortical hormone treatment, significantly higher than that in those who did not receive such treatment (2.13%). Patients who are at high risk of developing postoperative upper GI bleeding including that: age greater than 50 years; male; Glasgow Coma Score less than 10 pre and post operation; The lesion was located in brain stem and forth ventricle; Hypertensive cerebral hemorrhage; Intracerebral and intraventricular hemorrhagic brain trauma; Postoperative pneumonia, brain edema, encephalic high pressure, pyogenic infection of the central nervous system and other postoperative complications. The mortality of patients with postoperative upper GI bleeding was evidently higher than that of the patients without postoperative upper GI bleeding.

    The results of rectal mucosal electrosensitivity (RME) testing have been used to support theories regarding the aetiology of both idiopathic constipation and bowel dysfunction following rectopexy. The aim of this study was to assess the validity of tests of RME. Sixty-eight patients, comprising three groups (group 1: 50 patients undergoing assessment in the Anorectal Physiology Unit, group 2: 10 patients with coloanal or ileoanal anastomosis, group 3: 8 patients with a stoma) underwent mucosal electrosensitivity testing, with the threshold stimulus required to elicit sensation being recorded. In addition the RME was measured in groups 1 and 2 when placing the electrode, mounted on a catheter with a central wire, against the anterior, posterior, right and left rectal or neorectal walls. To asses the influence on this test of loss of mucosal contact due to faeces, a further 8 cases with a normal rectum had RME performed with and without a layer of water soaked gauze around the electrode to stimulate faeces and prevent the electrode from making contact with the rectal mucosa. There was marked variance in the sensitivity of the different regions of rectal wall tested (P < 0.001). In group 1 patients the mean sensitivities were: central 36.6 mA, anterior 27.4 mA, posterior 37.9 mA, right 22.3 mA and left 25.6 mA. This circumferential variation suggests that the pelvic floor rather than rectal mucosa was being stimulated. All patients in group 2 had recordable sensitivities, and the mean sensitivity threshold was significantly higher than group 1 patients in the central (P = 0.03), right (P = 0.03) and left (P = 0.007) positions. In group 3 the sensitivity was greater within the stoma at the level of the abdominal wall muscle than intra-abdominally or subcutaneously, again suggesting an extra-colonic origin of the sensation. The sensitivity threshold was significantly greater with the electrode wrapped in gauze (P < 0.01), and loss of mucosal contact was not detected by

    Bleeding complications are a serious adverse effect of medications that prevent abnormal blood clotting. To facilitate epidemiologic investigations of bleeding complications, we developed and validated an automated database case definition for bleeding-related hospitalizations. The case definition utilized information from an in-progress retrospective cohort study of warfarin-related bleeding in Tennessee Medicaid enrollees 30 years of age or older. It identified inpatient stays during the study period of January 1990 to December 2005 with diagnoses and/or procedures that indicated a current episode of bleeding. The definition was validated by medical record review for a sample of 236 hospitalizations. We reviewed 186 hospitalizations that had medical records with sufficient information for adjudication. Of these, 165 (89%, 95%CI: 83-92%) were clinically confirmed bleeding-related hospitalizations. An additional 19 hospitalizations (10%, 7-15%) were adjudicated as possibly bleeding-related. Of the 165 clinically confirmed bleeding-related hospitalizations, the automated database and clinical definitions had concordant anatomical sites (gastrointestinal, cerebral, genitourinary, other) for 163 (99%, 96-100%). For those hospitalizations with sufficient information to distinguish between upper/lower gastrointestinal bleeding, the concordance was 89% (76-96%) for upper gastrointestinal sites and 91% (77-97%) for lower gastrointestinal sites. A case definition for bleeding-related hospitalizations suitable for automated databases had a positive predictive value of between 89% and 99% and could distinguish specific bleeding sites.

    A 75-years-old man received external radiation with a cumulative dose of 60 Gy for prostatic cancer. Severe hematochezia occurred approximately 16 months after irradiation. A extensive and circumferential telangiectatic lesion in the lower segment of the rectum was detected, then he was diagnosed as having radiation proctitis. Pharmacotherapy was employed at first, but the bleeding was uncontrollable. Colostomy was performed, but the bleeding could not be controlled. Argon plasma coagulation therapy (APC) was applied, and the bleeding ceased after first session of APC. But the severe rectal stricture appeared three months after APC. APC is effective treatment for refractory radiation proctitis, but the rectal stenosis was occurred three months after APC. (author)

    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

    Full Text Available Abstract Background Within the last years, stapled rectal mucosectomy (SRM has become a widely accepted procedure for second and third degree hemorrhoids. One of the delayed complications is a stenosis of the lower rectum. In order to evaluate the specific problem of rectal stenosis following SRM we reviewed our data with special respect to potential predictive factors or stenotic events. Methods A retrospective analysis of 419 consecutive patients, which underwent SRM from December 1998 to August 2003 was performed. Only patients with at least one follow-up check were evaluated, thus the analysis includes 289 patients with a mean follow-up of 281 days (±18 days. For statistic analysis the groups with and without stenosis were evaluated using the Chi-Square Test, using the Kaplan-Meier statistic the actuarial incidence for rectal stenosis was plotted. Results Rectal stenosis was observed in 9 patients (3.1%, eight of these stenoses were detected within the first 100 days after surgery; the median time to stenosis was 95 days. Only one patient had a rectal stenosis after more than one year. 8 of the 9 patients had no obstructive symptoms, however the remaining patients complained of obstructive defecation and underwent surgery for transanal strictureplasty with electrocautery. A statistical analysis revealed that patients with stenosis had significantly more often prior treatment for hemorrhoids (p Conclusion Rectal stenosis is an uncommon event after SRM. Early stenosis will occur within the first three months after surgery. The majority of the stenoses are without clinical relevance. Only one of nine patients had to undergo surgery for a relevant stenosis. The predictive factor for stenosis in the patient-characteristics is previous interventions for hemorrhoids, severe postoperative pain might also predict rectal stenosis.

    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.

  8. Lateral rectal shielding reduces late rectal morbidity after high dose three-dimensional conformal radiation therapy for clinically localized prostate cancer: further evidence for a dose effect

    Purpose: Using conventional treatment methods for the treatment of clinically localized prostate cancer central axis doses must be limited to 65-70 Gy to prevent significant damage to nearby normal tissues. A fundamental hypothesis of three-dimensional conformal radiation therapy (3DCRT) is that, by defining the target organ(s) accurately in three dimensions, it is possible to deliver higher doses to the target without a significant increase in normal tissue complications. This study examines whether this hypothesis holds true and whether a simple modification of treatment technique can reduce the incidence of late rectal morbidity in patients with prostate cancer treated with 3DCRT to minimum planning target volume (PTV) doses of 71-75 Gy. Materials and Methods: 257 patients with clinically localized prostate cancer completed 3DCRT by December 31, 1993 and received a minimum PTV dose of 71-75 Gy. The median follow-up time was 22 months (range 4-67 months) and 98% of patients had followup of longer than 12 months. The calculated dose at the center of the prostate was <74 Gy in 19 patients, 74-76 Gy in 206 patients and >76 Gy in 32 patients. Late rectal morbidity was graded according to the LENT scoring system. Eighty-eight consecutive patients were treated with a rectal block added to the lateral fields. In these patients the posterior margin from the prostate to the block edge was reduced from the standard 15 mm to 7.5 mm for the final 10 Gy which reduced the dose to portions of the anterior rectal wall by approximately 4-5 Gy. Estimates of rates for rectal morbidity were determined by Kaplan-Meier actuarial analyses. Differences in morbidity percentages were evaluated by the Pearson chi square test. Results: Grade 2-3 rectal morbidity developed in 46 of 257 patients (18%) and in the majority of cases consisted of rectal bleeding. No patient has developed grade 4 or 5 rectal morbidity. The actuarial rate of grade 2-3 morbidity is 22% at 24 months and the median

    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

    To assess the demographic, clinical, endoscopic and histological spectrum of Solitary Rectal Ulcer Syndrome (SRUS). Study Design: Cross-sectional observational study. Place and Duration of Study: Medical Unit-III, Civil Hospital Karachi (CHK) and Ward 7, Jinnah Postgraduate Medical Centre (JPMC), Karachi, from January 2009 to June 2012. Methodology: Patients with SRUS, based on characteristic endoscopic and histological findings, were enrolled. Patients were excluded if they had other causes of the rectal lesions (neoplasm, infection, inflammatory bowel disease, and trauma). Endoscopically, lesions were divided on the basis of number (solitary or multiple) and appearance (ulcerative, polypoidal/nodular or erythematous mucosa). Demographic, clinical and endoscopic characteristics of subjects were evaluated. Results: Forty-four patients met the inclusion criteria; 21 (47.7%) were females and 23 (52.3%) were males with overall mean age of 33.73 ±13.28 years. Symptom-wise 41 (93.2%) had bleeding per rectum, 39 (88.6%) had mucous discharge, 34 (77.3%) had straining, 34 (77.3%) had constipation, 32 (72.7%) had tenesmus, 5 (11.4%) had rectal prolapse and 2 (4.5%) had fecal incontinence. Twelve (27.27%) patients presented with hemoglobin less 10 gm/dl, 27 (61.36%) with 10 - 12 gm/dl and 05 (11.36%) subjects had hemoglobin more than 12 gm/dl. Endoscopically, 26 (59.1%) patients had mucosal ulceration, 11 (25.0%) had mucosal ulceration with polypoid characteristics; while only polypoid features were found in 7 (15.9%) subjects. Conclusion: Solitary rectal ulcer syndrome affects adults of both genders with diverse clinical presentation and nonspecific endoscopic features. (author)

    Alimentary tract duplications represent rare anomalies, with only 5 % occurring in the rectum. The variety in clinical presentation may lead to a delay in diagnosis or to incorrect and multiple surgical procedures. We report the clinical, histological and immunohistochemical characteristics of a rectal duplication occurring in a 3-month-old male with an unusual clinical presentation. Using routine histology and immunohistochemistry, the rectal duplication showed the diffuse presence of gastric mucosa with a characteristic immunophenotype (i.e., diffuse cytokeratin 7 positivity and scattered chromogranin immunoreactivity). As far as we know, this is the first report showing an immunohistochemical differentiation pattern of gastric lining in a rectal duplication. Our results, showing the presence of gastric mucosa, are suggestive of a possible origin from the embryonic foregut.

  13. Small Bowel Dose Parameters Predicting Grade ≥3 Acute Toxicity in Rectal Cancer Patients Treated With Neoadjuvant Chemoradiation: An Independent Validation Study Comparing Peritoneal Space Versus Small Bowel Loop Contouring Techniques

    Purpose: To determine whether volumes based on contours of the peritoneal space can be used instead of individual small bowel loops to predict for grade ≥3 acute small bowel toxicity in patients with rectal cancer treated with neoadjuvant chemoradiation therapy. Methods and Materials: A standardized contouring method was developed for the peritoneal space and retrospectively applied to the radiation treatment plans of 67 patients treated with neoadjuvant chemoradiation therapy for rectal cancer. Dose-volume histogram (DVH) data were extracted and analyzed against patient toxicity. Receiver operating characteristic analysis and logistic regression were carried out for both contouring methods. Results: Grade ≥3 small bowel toxicity occurred in 16% (11/67) of patients in the study. A highly significant dose-volume relationship between small bowel irradiation and acute small bowel toxicity was supported by the use of both small bowel loop and peritoneal space contouring techniques. Receiver operating characteristic analysis demonstrated that, for both contouring methods, the greatest sensitivity for predicting toxicity was associated with the volume receiving between 15 and 25 Gy. Conclusion: DVH analysis of peritoneal space volumes accurately predicts grade ≥3 small bowel toxicity in patients with rectal cancer receiving neoadjuvant chemoradiation therapy, suggesting that the contours of the peritoneal space provide a reasonable surrogate for the contours of individual small bowel loops. The study finds that a small bowel V15 less than 275 cc and a peritoneal space V15 less than 830 cc are associated with a less than 10% risk of grade ≥3 acute toxicity

  14. Radiological imaging of rectal cancer

    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.

    2007-01-01

    Purpose: The variability of dose-volume histogram (DVH) shapes in a patient population can be quantified using principal component analysis (PCA). We applied this to rectal DVHs of prostate cancer patients and investigated the correlation of the PCA parameters with late bleeding. Methods and Materials: PCA was applied to the rectal wall DVHs of 262 patients, who had been treated with a four-field box, conformal adaptive radiotherapy technique. The correlated changes in the DVH pattern were revealed as 'eigenmodes,' which were ordered by their importance to represent data set variability. Each DVH is uniquely characterized by its principal components (PCs). The correlation of the first three PCs and chronic rectal bleeding of Grade 2 or greater was investigated with uni- and multivariate logistic regression analyses. Results: Rectal wall DVHs in four-field conformal RT can primarily be represented by the first two or three PCs, which describe ∼94% or 96% of the DVH shape variability, respectively. The first eigenmode models the total irradiated rectal volume; thus, PC1 correlates to the mean dose. Mode 2 describes the interpatient differences of the relative rectal volume in the two- or four-field overlap region. Mode 3 reveals correlations of volumes with intermediate doses (∼40-45 Gy) and volumes with doses >70 Gy; thus, PC3 is associated with the maximal dose. According to univariate logistic regression analysis, only PC2 correlated significantly with toxicity. However, multivariate logistic regression analysis with the first two or three PCs revealed an increased probability of bleeding for DVHs with more than one large PC. Conclusions: PCA can reveal the correlation structure of DVHs for a patient population as imposed by the treatment technique and provide information about its relationship to toxicity. It proves useful for augmenting normal tissue complication probability modeling approaches

    We report our experience of concomitant laparoscopic treatment for enterocele and stapled transanal rectal resection (STARR) for rectocele and/or rectal prolapse in patients with complex obstructed defecation syndrome (ODS). From June 2005 to June 2007, we submitted 20 patients with ODS due to rectal prolapse and/or rectocele, combined with stable enterocele, to STARR and laparoscopic correction of the enterocele. Preoperative assessment included symptom evaluation with standardized questionnaires, clinical examination, colonoscopy, proctoscopy, anal sphincter ultrasonography, video-defecography with synchronous opacification of the ileal loops in all patients and colpography in female patients, and anorectal manometry. Follow-up was performed in the first, third, sixth, 12th, and 24th month after surgery. Eighteen (90%) patients were submitted to both procedures, simultaneously. One patient, previously submitted to STARR, underwent laparoscopic treatment of the enterocele. Postoperative complications occurred in two (10%) patients: one case of postoperative rectal bleeding and one case of retropneumoperitoneum. Median (range) preoperative and postoperative Altomare's obstructed defecation score was ten (6-14) and two (0-14), respectively (p<0.001). Median (range) preoperative and postoperative quality of life score was 79 (39-109) and 109 (50-126), respectively (p<0.001). No symptom related to ODS was detected at 6-month follow-up (19 patients) and at 24-month follow-up (19 patients). The combination of STARR and laparoscopy provides a safe and effective method to treat ODS caused by rectal internal prolapse and/or rectocele combined with enterocele.

    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

  5. Treatment and prognosis in peptic ulcer bleeding.

    2014-01-01

    Peptic ulcer bleeding is a frequent cause of admission. Despite several advances in treatment the 30-day mortality seems unchanged at a level around 11%. Use of risk scoring systems is shown to be advantageous in the primary assessment of patients presenting with symptoms of peptic ulcer bleeding. Studies performed outside Denmark have demonstrated that use of risk scoring systems facilitates identification of low-risk patients suitable for outpatient management. Nevertheless, these systems have not been implemented for routine use in Denmark. This is mainly explained by concerns about the external validity due to considerable inter-country variation in patients' characteristics. In recent years, transcatheter arterial embolization (TAE) has become increasingly used for achievement of hemostasis in patients with peptic ulcer bleeding not responding to endoscopic therapy. As rebleeding is associated with poor outcome TAE could, in theory, also be beneficial as a supplementary treatment in patients with ulcer bleeding responding to endoscopic therapy. This has not been examined previously. Several studies have concluded that peptic ulcer bleeding is associated with excess long-term mortality. These findings are, however, questioned as the studies were based on life-table analysis, unmatched control groups, or did not perform adequate adjustment for comorbidity. Treatment with blood transfusion is, among patients undergoing cardiac bypass surgery, shown to increase the long-term mortality. Despite frequent use of blood transfusion in treatment of peptic ulcer bleeding a possible adverse effect of on long-term survival has not been examined in these patients. The aims of the present thesis were: 1. To examine which risk scoring system is best at predicting need of hospital-based intervention, rebleeding, and mortality in patients presenting with upper gastrointestinal bleeding (Study I) 2. To evaluate if supplementary transcatheter arterial embolization (STAE) after

    Preoperative diagnosis of the depth of invasion and lymph node metastasis of rectal cancer were studied using the findings of computed tomography (CT). Of one hundred and four cases operated on for rectal cancer over a period of 32 months, thirty five cases were examined by CT with the use of olive oil enema and contrast enhancement using a 60 % Conray drip infusion with reference to the histological findings. For direct invasion into the wall, the diagnoses by CT were coincident with microscopic findings in 75 % of cancers of the rectosigmoid, in 75 % of the upper rectum and in 84 % of the lower rectum. Of all cases, 28 (80 %) were diagnosed correctly. As to local lymph node metastasis, 74 % of all diagnoses by CT corresponded with the histological diagnosis. Moreover, seventeen cases were evaluated for lateral lymph node metastasis, and the diagnostic accuracy by CT was 88 %. In conclusion, preoperative CT evaluation of the extension into the rectal wall and lymph node metastasis in rectal cancer was considesed useful. (author)

  13. Approach to Rectal Cancer Surgery

    2012-01-01

    Full Text Available Rectal cancer is a distinct subset of colorectal cancer where specialized disease-specific management of the primary tumor is required. There have been significant developments in rectal cancer surgery at all stages of disease in particular the introduction of local excision strategies for preinvasive and early cancers, standardized total mesorectal excision for resectable cancers incorporating preoperative short- or long-course chemoradiation to the multimodality sequencing of treatment. Laparoscopic surgery is also increasingly being adopted as the standard rectal cancer surgery approach following expertise of colorectal surgeons in minimally invasive surgery gained from laparoscopic colon resections. In locally advanced and metastatic disease, combining chemoradiation with radical surgery may achieve total eradication of disease and disease control in the pelvis. Evidence for resection of metastases to the liver and lung have been extensively reported in the literature. The role of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal metastases is showing promise in achieving locoregional control of peritoneal dissemination. This paper summarizes the recent developments in approaches to rectal cancer surgery at all these time points of the disease natural history.

    2013-01-01

    OBJECTIVES: Our purpose was to compare the efficacy, complications, success rate, recurrence rate at 1 year, and crossovers of rubber band ligation (RBL) with those of bipolar electrocoagulation (BPEC) treatment for chronically bleeding internal hemorrhoids. METHODS: A total of 45 patients of mean age 51.5 years, who had rectal bleeding from grade II or III hemorrhoids and in whom intensive medical therapy failed, were randomized in a prospective study comparing RBL with BPEC. Treatment failure was predefined as continued bleeding, occurrence of a major complication, or failure to reduce the size of all internal hemorrhoidal segments to grade I in ≤ 3 treatments. Patients were followed up for 1 year. RESULTS: With similar patients, rectal bleeding and other symptoms were controlled with significantly fewer treatments of RBL than of BPEC (2.3±0.2 vs. 3.8±0.4, P 0.05), but significantly fewer failures and crossovers (8% vs. 38%). Symptomatic recurrence at 1 year was 10% RBL and 15% BPEC. CONCLUSIONS: For patients with chronically bleeding grade II or III internal hemorrhoids that are unresponsive to medical therapy, safety and complication rates of banding and BPEC were similar. The success rate was significantly higher with RBL than with BPEC. Symptom recurrence rates at 1 year were similar. PMID:19513028

    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.

    PURPOSE: This report will summarize symptom palliation, complication rate, and survival outcome of an aggressive reirradiation policy for patients with recurrent rectal cancer. MATERIALS and METHODS: From 1987 - 1993, 83 patients with recurrent rectal adenocarcinoma following previous pelvic irradiation (RT) underwent reirradiation. Thirty-one patients were treated with radical intent, and underwent reirradiation followed by planned surgical resection. The remaining fifty-two patients underwent reirradiation alone and are the basis of this study. Median initial RT dose was 50.4 Gy (range 40.0 - 70.2 Gy), and median time to recurrence was 24 months. Reirradiation was delivered with two lateral fields (7x7 - 12x10 cm) encompassing recurrent tumor with a minimum of 2 cm margin and excluding all small bowel. Thirty patients received 1.8 - 2.0 Gy daily fractions, and 22 patients received 1.2 Gy BID fractions. Median reirradiation dose was 30.6 Gy (range 19.8 - 40.8 Gy). Median total cumulative dose was 84.6 Gy (range 66.6 - 104.9 Gy). Forty-seven of the 52 patients received concurrent 5-FU based chemotherapy. Median follow up for the entire group was 16 months (range 2 - 53 months). Eight patients who remain alive at the time of this study had a median follow up of 22 months (range 13 - 48 months). RESULTS: Patients' presenting symptoms included bleeding, pain and mass effect. Results of treatment are shown in Table 1. Treatment was well tolerated. Using the RTOG toxicity scale, 16 patients required a treatment break for grade 3 toxicity including severe diarrhea, moist desquamation, and mucositis. No patient developed grade 4 acute toxicity. Eighteen patients (35%) developed late grade 3 or 4 morbidity, including bowel obstruction in 9 patients, cystitis in 3 patients, fistula in 4 patients and skin ulceration in 1 patient. There was no difference in incidence of late complications by time to recurrence, reirradiation dose, or total cumulative dose. However, there was

    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. 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. 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). 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.

    Full Text Available There are no widely used models in clinical care to predict outcome in acute lower gastro-intestinal bleeding (ALGIB. If available these could help triage patients at presentation to appropriate levels of care/intervention and improve medical resource utilisation. We aimed to apply a state-of-the-art machine learning classifier, gradient boosting (GB, to predict outcome in ALGIB using non-endoscopic measurements as predictors.Non-endoscopic variables from patients with ALGIB attending the emergency departments of two teaching hospitals were analysed retrospectively for training/internal validation (n=170 and external validation (n=130 of the GB model. The performance of the GB algorithm in predicting recurrent bleeding, clinical intervention and severe bleeding was compared to a multiple logic regression (MLR model and two published MLR-based prediction algorithms (BLEED and Strate prediction rule.The GB algorithm had the best negative predictive values for the chosen outcomes (>88%. On internal validation the accuracy of the GB algorithm for predicting recurrent bleeding, therapeutic intervention and severe bleeding were (88%, 88% and 78% respectively and superior to the BLEED classification (64%, 68% and 63%, Strate prediction rule (78%, 78%, 67% and conventional MLR (74%, 74% 62%. On external validation the accuracy was similar to conventional MLR for recurrent bleeding (88% vs. 83% and therapeutic intervention (91% vs. 87% but superior for severe bleeding (83% vs. 71%.The gradient boosting algorithm accurately predicts outcome in patients with acute lower gastrointestinal bleeding and outperforms multiple logistic regression based models. These may be useful for risk stratification of patients on presentation to the emergency department.

    Capsule endoscopy (CE) is the gold standard to diagnose small bowel bleeding. The "suspected blood indicator" (SBI) offers an automated detection of active small bowel bleeding but validity of this technique is unknown. The objective was to analyze specificity and sensitivity of the SBI using the second small bowel capsule generation for the detection of active bleeding. This is a retrospective analysis of all patients (199) who attended our clinic for CE from June 2008 through March 2013. The second-generation PillCam SB 2 capsule was used for detection of (1) luminal blood content and (2) potentially responsible small bowel lesions. The findings of an independent investigator were correlated to SBI findings and a number of SBI markings were analyzed by a receiver operating characteristic (ROC). In 157/199 cases, no sign of active bleeding or altered blood was detected. One hundred and thirty-seven of these 157 cases provided at least one SBI marking and a mean of 18.4 positive SBI markings per record were found. In 20 cases, neither SBI nor the human investigator detected abnormalities. Thirteen patients showed investigator-detected minor bleeding with mean SBI findings of 36 positive screenshots per record. When major bleeding was diagnosed by the investigator (n = 29), SBI detected a mean of 46.6 SBI-positive markings. SBI turned positive in 179 patients, whereas the investigator detected active bleeding in 42 cases. All patients with active bleeding were detected by SBI (sensitivity 100%, specificity 13%). ROC analysis revealed 51.0 SBI markings being the optimal cutoff for active versus no bleeding (sensitivity 79.1%, specificity 90.4%, misclassification of 15.3%). The new SBI software is a reliable tool to exclude active bleeding and/or major lesions but analysis of the CE video by a trained investigator is still important for the detection of lesions responsible for past bleeding.

    Factor VII deficiency, although rare, is now recognized as the most common autosomal recessive inherited factor deficiency. It is usually considered to be associated with bleeding only in the severely affected subject and heterozygotes (>10%) are not considered at risk. The general recommendation for surgery is to achieve a FVII level in excess of 15% (0.15 1U/mL). We present three cases of severe factor VII deficiency, each of whom appeared hemostatically competent based on clinical history. Subject 1 is a 33 year-old African-American female with a baseline FVII of American female with a factor VII level of 9% who underwent an elective left total hip replacement without any factor replacement and had no excessive bleeding, but who sustained a pulmonary embolism postoperatively. Subject 3 is a 19-year-old African-American male with a baseline FVII of 1% with a history of active participation in football without noticeable injury and who underwent an emergent appendectomy without bleeding. These three cases represent individuals with the severe form of FVII deficiency who did not exhibit excessive bleeding when challenged with surgical procedures. The clinical history would appear the most valuable tool in predicting the likelihood of bleeding in these patients, and we suggest that the presumption that all patients with severe FVII deficiency should receive replacement therapy before surgical procedures may not be valid in all cases.

    Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office or primary-care setting. The wider availability of diagnostic tools has allowed prompt diagnosis and treatment of an increasing number of menstrual disorders in an office setting. This White Paper reviews the advantages and disadvantages of transvaginal ultrasound, blind endometrial sampling and diagnostic hysteroscopy. Once a proper diagnosis has been established, appropriate therapy may be embarked upon. Fortunately, only a minority of such patients will have premalignant or malignant disease. When bleeding is sufficient to cause severe anemia or even hypovolemia, prompt intervention is called for. In most of the cases, however, the abnormal uterine bleeding will be disquieting to the patient and significantly affect her 'quality of life'. Sometimes, reassurance and expectant management will be sufficient in such patients. Overall, however, in cases of benign disease, some intervention will be required. The use of oral contraceptive pills especially those with a short hormone-free interval, the insertion of the levonorgestrel intrauterine system, the incorporation of newer medical therapies including antifibrinolytic drugs and selective progesterone receptor modulators and minimally invasive treatments have made outpatient therapy increasingly effective. For others, operative hysteroscopy and endometrial ablation are proven therapeutic tools to provide both long- and short-term relief of abnormal uterine bleeding, thus avoiding, or deferring, hysterectomy.

  5. Radiological diagnosis of gastrointestinal bleeding

    In the diagnosis of acute gastrointestinal bleeding, endoscopy holds the first place today. Radiological investigations are indispensable whenever endoscopy cannot precisely localise the bleeding site, whenever a tumour is present or suspected, in all cases of lower gastrointestinal bleeding, and in haemobilia. A tailored radiological approach is recommended. The radiological basis programme should be at least a complete abdominal ultrasound study and plain abdominal radiograms. CT and ERCP scans may become necessary in selected cases. As a rule, angiographical localisation of the bleeding site will be successful only in the acute stage; selective visceral arteriograms have to be obtained, which may be executed in the digital subtraction technique in patients who are cooperating and clinically stable. Angiodysplasias and aneurysms, however, may be demonstrated angiographically in the interval as well. Upper and/or lower G.I. tract studies with barium or water-soluble contrast media may be indicated in the interval in order to demonstrate tumours, metastatic lesions, diverticula and gut malformations.

    Rectal stenosis is a common condition caused by a wide variety of diseases, including both intrinsic and extrinsic disorders, as well as both malignant and benign pathologies. Barium enema, CT, and MRI are the primary modalities for the evaluation of the disease, and careful observation of the characteristic radiologic features usually leads to correct diagnosis. However, some of the lesions looks very similar and are difficult to differentiate from each other. The purpose of this study is to review the literature on diseases that cause rectal stenosis, to clarify the characteristics of radiologic features, and to suggest the limitations in differential diagnosis. Deliberate analysis of these imaging features and correlation with clinical manifestations can facilitate a more specific diagnosis. (orig.)

    Accurate preoperative staging of rectal cancer is crucial for therapeutic decision making, as local tumor extent, nodal status, and patterns of metastatic spread are directly associated with different treatment strategies. Recently, treatment approaches have been widely standardized according to large studies and consensus guidelines. Introduced by Heald, total mesorectal excision (TME) is widely accepted as the surgical procedure of choice to remove the rectum together with its enveloping tissues and the mesorectal fascia. Neoadjuvant radiochemotherapy also plays a key role in the treatment of locally advanced stages, while the use of new drugs will lead to a further improvement in oncological outcome. Visualization of the circumferential resection margin is the hallmark of any preoperative imaging and a prerequisite for high-quality TME surgery. The aim of this article is to present an overview on current cross-sectional imaging with emphasis on magnetic resonance imaging. Future perspectives in rectal cancer imaging are addressed. (orig.)

    Background and purpose: The rectum is known to display a dose-volume effect following high-dose 3D-conformal radiotherapy (3D-CRT). The aim of the study is to search for significant dose-volume combinations with the specific treatment technique and patient set-up currently used in our institution. Patients and methods: We retrospectively analyzed the dose-volume histograms (DVH) of 135 patients with stage T1b-T3b prostate cancer treated consecutively with 3D-CRT between 1996 and 2000 to a total dose of 76 Gy. The median follow-up was 28 months (range 12-62). All late rectal complications were scored using RTOG criteria. Time to late toxicity was assessed using the Kaplan-Meyer method. The association between variables at baseline and ≥2 rectal toxicity was tested using χ 2 test or Fisher's exact test. A multivariate analysis using logistic regression was performed. Results: Late rectal toxicity grade ≥2 was observed in 24 of the 135 patients (17.8%). A 'grey area' of increased risk has been identified. Average DVHs of the bleeding and non-bleeding patients were generated. The area under the percent volume DVH for the rectum of the bleeding patients was significantly higher than that of patients without late rectal toxicity. On multivariate analysis the correlation between the high risk DVHs and late rectal bleeding was confirmed. Conclusions: The present analysis confirms the role of the rectal DVH as a tool to discriminate patients undergoing high-dose 3D-CRT into a low and a high risk of developing late rectal bleeding. Based on our own results and taking into account the data published in the literature, we have been able to establish new dose-volume constraints for treatment planning: if possible, the percentage of rectal volume exposed to 40, 50, 60, 72 and 76 Gy should be limited to 60, 50, 25, 15 and 5%, respectively

    Duplications of the gastrointestinal (GI) tract are rare. Only 5% of them are rectal and there are very few reports of rectal prolapse (RP) caused by a duplication. An 11 month-old female presented with a RP caused by a blind-ended anterior tubular colorectal duplication. The duplication was successfully opened and connected to the normal rectum without complications. Although infrequent, a rectal duplication should be considered in the differential diagnosis of RP.

    The suggested classifications of locally recurrent rectal cancer are based on the presence of symptoms and the degree of tumour fixation to the pelvic wall, or, otherwise, account for factor T in the TMN system. Although the results of rectal cancer treatment have improved, which may be attributed to total meso rectal excision and application of perioperative radiotherapy and radiochemotherapy, the ratio of cases of locally recurrent rectal cancer still amount from several to over a dozen percent. Among the available diagnostic methods for detecting locally recurrent rectal cancer after anterior rectal resection, endorectal sonography is of special importance. In the estimation of prognostic factors the lack of vascular invasion in recurrent cancer and the long period between the treatment of primary rectal cancer and the development of recurrence are a sign of good prognosis, while pain prior to recurrence treatment and male sex diminish the chances for cure. Locally recurrent rectal cancer impairs the patient's quality of life in all measurable aspects, but even after complete recovery we observe severe disturbances of sexual activity in most patients, and a number of patients require hygiene pads or suffer from chronic pain. Local recurrence of rectal cancer is more commonly qualified for excision after surgical treatment only, than after preoperative radiotherapy. The probability of total recurrent rectal cancer excision increases when the patient is younger, the primary tumours was less advanced and the first operation was sphincter-sparing surgery. Progress in the surgical treatment of recurrent rectal cancer was brought on by the introduction of the composite musculocutaneous flap to compensate the loss of perineal tissue. The application of intraoperative radiotherapy improves treatment results of recurrent rectal cancer, however at the cost of more frequent, serious postoperative complications and intense pain. In inoperable cases high dose regional

    The prevalence of bleeding disorders, notably von Willebrand disease (vWD), among adult women with objectively documented menorrhagia is consistently reported to be 10% to 20% and is even higher in adolescents presenting with menorrhagia. This consensus document has been developed by a multidisciplinary committee consisting of an anesthesiologist, 2 hematologists, and an obstetrician/gynaecologist and has been endorsed by their relevant specialty bodies. It has been prepared with the express purpose of providing guidelines for both women with inherited bleeding disorders and for their caregivers regarding the gynaecological and obstetric management of these women, including appropriate anesthesia support where indicated. Diagnostic tools and specific medical and, where appropriate, surgical alternatives to management are reviewed and evidence-based recommendations presented. A MEDLINE search of the English literature between January 1975 and November 2003 was performed using the following key words: menorrhagia, uterine bleeding, pregnancy, von Willebrand, congenital bleeding disorder, desmopressin/DDAVP, tranexamic acid, oral contraceptives, medroxyprogesterone, therapy, hysterectomy, anesthesia, epidural, spinal. Recommendations from other society guidelines were reviewed. 1. Inherited bleeding disorders should be considered in the differential diagnosis of all patients presenting with menorrhagia (II-2B). The graphical scoring system presented is a validated tool which offers a simple yet practical method that can be used by patients to quantify their blood loss (II-2B). 2. Because underlying bleeding disorders are frequent in women with menorrhagia, physicians should consider performing a hemoglobin/hematocrit, platelet count, ferritin, PT (INR) and APTT in women with menorrhagia. In women who have a personal history of other bleeding or a family history of bleeding, further investigation should be considered, including a vWD workup (factor VIII, vWF antigen

    Purpose: To evaluate the dynamic interrelationship between rectal distension and rectal movements, and to determine the effect of rectal movement on the position of the prostatic gland using cine magnetic resonance imaging (MRI). Methods and Materials: Fifty-five patients with biopsy-proven or suspected prostate cancer were examined in the axial plane using repeated spoiled gradient-echo sequences every 10 seconds for 7 minutes. Twenty-four patients received bowel relaxants before imaging. Images were analyzed for the degree of rectal distension, for the incidence, magnitude, and number of rectal and prostate movements. Results: Rectal movements were seen in 28 (51%) patients overall, in 10 (42%) of those receiving bowel relaxants and in 18 (58%) not receiving bowel relaxants. The incidence of rectal movements correlated with the degree of rectal distension (p = 0.0005), but the magnitude of rectal movements did not correlate with the degree of rectal distension. Eighty-six rectal movements resulting in 33 anterior-posterior (AP) prostate movements were seen. The magnitude of rectal movements correlated well with degree of prostate movements (p < 0.001). Prostate movements in the AP direction were seen in 16 (29%) patients, and in 9 (16%) patients the movement was greater than 5 mm. The median prostate AP displacement was anterior by 4.2 (-5 to +14 mm). Conclusions: Cine MRI is able to demonstrate near real time rectal and associated prostate movements. Rectal movements are related to rectal distension and result in significant displacements of the prostate gland over a time period similar to that used for daily fractionated radiotherapy treatments. Delivery of radiotherapy needs to take into account these organ movements

    Purpose: To test the feasibility of a new approach to synthesize published normal tissue complication data using late rectal toxicity in prostate cancer as an example. Methods and Materials: A data survey was performed to identify the published reports on the dose–response relationships for late rectal toxicity. The risk estimates for Grade 1 or greater, Grade 2 or greater, and Grade 3 or greater toxicity were obtained for a test cohort of patients treated at our institution. The influence of the potential factors that might have affected the reported toxicity levels was investigated. The studies that did not conform to the general data trends were excluded, and single, combined risk estimates were derived for each patient and toxicity level. Results: A total of 21 studies of nonoverlapping patient populations were identified. Three studies provided dose–response models for more than one level of toxicity. Of these 21 studies, 6, 14, and 5 were used to derive the initial risk estimates for Grade 1, 2, and 3 or greater toxicity, respectively. A comparison of risk estimates between the studies reporting rectal bleeding and rectal toxicity (bleeding plus other symptoms) or between studies with follow-up <36 months and ≥36 months did not reveal significant differences (p ≥ .29 for all comparisons). After excluding three reports that did not conform to the general data trends, the combined risk estimates were derived from 5 reports (647 patients), 11 reports (3,369 patients), and 5 reports (1,330 patients) for Grade 1, 2, and 3 or greater toxicity, respectively. Conclusions: The proposed approach is feasible and allows for more systematic use of published dose–response data to estimate the complication risks for the individual patient.

The studies that did not conform to the general data trends were excluded, and single, combined risk estimates were derived for each patient and toxicity level. Results: A total of 21 studies of nonoverlapping patient populations were identified. Three studies provided dose-response models for more than one level of toxicity. Of these 21 studies, 6, 14, and 5 were used to derive the initial risk estimates for Grade 1, 2, and 3 or greater toxicity, respectively. A comparison of risk estimates between the studies reporting rectal bleeding and rectal toxicity (bleeding plus other symptoms) or between studies with follow-up <36 months and {>=}36 months did not reveal significant differences (p {>=} .29 for all comparisons). After excluding three reports that did not conform to the general data trends, the combined risk estimates were derived from 5 reports (647 patients), 11 reports (3,369 patients), and 5 reports (1,330 patients) for Grade 1, 2, and 3 or greater toxicity, respectively. Conclusions: The proposed approach is feasible and allows for more systematic use of published dose-response data to estimate the complication risks for the individual patient.

    Purpose: Although several institutions have reported rectal dose constraints according to threshold toxicity, the plethora of trials has resulted in multiple, confusing dose-volume histogram recommendations. A set of standardized, literature-based constraints for patients undergoing whole pelvic radiotherapy (RT) for prostate cancer would help guide the practice of prostate RT. The purpose of this study was to develop these constraints, demonstrate that they are achievable, and assess the corresponding rectal toxicity. Methods and Materials: An extensive literature search identified eight key studies relating dose-volume histogram data to rectal toxicity. A correction factor was developed to address differences in the anatomic definition of the rectum across studies. The dose-volume histogram constraints recommended by each study were combined to generate the constraints. The data from all patients treated with definitive intensity-modulated RT were then compared against these constraints. Acute rectal toxicity was assessed. Results: A continuous, proposed rectal dose-constraint curve was generated. Intensity-modulated RT not only met this constraint curve, but also was able to achieve at least 30-40% lower dose to the rectum. The preliminary clinical results were also positive: 50% of patients reported no acute bowel toxicity, 33% reported Grade 1 toxicity, and 17% reported Grade 2 toxicity. No patients reported Grade 3-4 acute rectal toxicity. Conclusions: In this study, we developed a set of proposed rectal dose constraints. This allowed for volumetric assessment of the dose-volume relationship compared with single dose-volume histogram points. Additional research will be performed to validate this threshold as a class solution for rectal dose constraints

    Introduction: Rectal cancer causes about 500 deaths a year in our country. Radio chemotherapy (RTCT) is part of the treatment of rectal tumors especially in stages II and III. The indication for neoadjuvant aims to preserve the sphincter at low tumors and potentially make initially unresectable tumors resectable. Objective: To analyze the indications, treatment, toxicity and development of adenocarcinoma patients receiving treatment rectum preoperative R T ± Q T. Patients and Methods: Retrospective analysis of 31 records of patients rectal adenocarcinoma treated with neoadjuvant in Oncology Services Hospital and Central Clinical Hospital of the Armed Forces between 1994 and , 2003. Results: Men / Women: 1.3. Median age 64 years. Eight patients (30%) endorectal ultrasound as preoperative staging were performed. patients matched 20 (65%) stage II, 6 (19%) stage III, 5 (16%) stage IV with potentially resectable liver metastases. The median dose of R T was 50 Gy (35.8-63 Gy) with a median duration was 5 weeks (4-12). One patient (3%) received exclusive R T. Plans Q T used: 5-F U in I / C 52%, 5-F U bolus and 42% leucovorin and 5-F U bolus 3%. Surgery was achieved with sphincter preservation in 7/31 cases (23%). The most common toxicity was diarrhea and radiodermatitis were the cause of discontinuation in 4 patients. Control hematologic weekly was 38% during the RTCT. Responses were achieved Full 5% partial 39%, 17% and stabilization lesion progression 39%. Discussion: The lack of information recorded in the medical records hindered the Analysis of this work. 70% of stage II and III patients were incompletely staged (30% endorectal ultrasound) and controls during treatment were suboptimal. Only 23% of patients achieved sphincter preservation, lower than the figures reported in the literature (65-

    Purpose: To find predictors for rectal and intestinal acute toxicity in patients with prostate cancer treated with ≥70 Gy conformal radiotherapy. Methods and Materials: Between July 2002 and March 2004, 1,132 patients were entered into a cooperative study (AIROPROS01-02). Toxicity was scored using the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer scale and by considering the changes (before and after treatment) of the scores of a self-administered questionnaire on rectal/intestinal toxicity. The correlation with a number of parameters was assessed by univariate and multivariate analyses. Concerning the questionnaire, only moderate/severe complications were considered. Results: Of 1,132 patients, 1,123 were evaluable. Of these patients, 375, 265, and 28 had Grade 1, 2, and 3 Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer toxicity, respectively. The mean rectal dose was the most predictive parameter (p = 0.0004; odds ratio, 1.035) for Grade 2 or worse toxicity, and the use of anticoagulants/antiaggregants (p 0.02; odds ratio, 0.63) and hormonal therapy (p = 0.04, odds ratio, 0.65) were protective. The questionnaire-based scoring revealed that a greater mean rectal dose was associated with a greater risk of bleeding; larger irradiated volumes were associated with frequency, tenesmus, incontinence, and bleeding; hormonal therapy was protective against frequency and tenesmus; hemorrhoids were associated with a greater risk of tenesmus and bleeding; and diabetes associated highly with diarrhea. Conclusion: The mean rectal dose correlated with acute rectal/intestinal toxicity in three-dimensional conformal radiotherapy for prostate cancer, and hormonal therapy and the use of anticoagulants/antiaggregants were protective. According to the moderate/severe injury scores on the self-assessed questionnaire, several clinical and dose-volume parameters were independently predictive for

    2015-01-01

    Purpose: Some investigators have reported severe rectal complications after brachytherapy. Due to the low number of such events, their relationship to dosimetric parameters has not been well characterized. Methods and materials: A total of 3126 patients were treated with low dose rate brachytherapy from 1998 through 2010. 2464 had implant alone, and 313 had implant preceded by 44–46 Gy supplemental external beam radiation (EBRT). Post-implant dosimetry was based on a CT scan obtained on the day of implant, generally within 30 min of the procedure. Every patient’s record was reviewed for occurrence of rectal complications. Results: Eight of 2464 patients (0.32%) treated with brachytherapy alone developed a radiation-related rectal fistula. Average prostatic and rectal dose parameters were moderately higher for fistula patients than for patients without a severe rectal complication. For instance, the average R100 was 1.2 ± 0.75 cc for fistula patients, versus 0.37 ± 0.88 cc for non-fistula patients. However, the fistula patients’ values were well within the range of values for patients without a rectal complication. Four patients had some attempt at repair or reconstruction, but long-term functional outcomes were not favorable. Conclusions: Rectal fistulas are a very uncommon potential complication of prostate brachytherapy, which can occur even in the setting of acceptable day 0 rectal doses. Their occurrence is not easily explained by standard dosimetric or clinical factors

    A case of radiation-induced rectal cancer is presented. In November, 1971, a 58-year-old woman had a stage II squamous cell carcinoma in the uterine cervix. She underwent a hysterectomy and postoperative radiotherapy. External pelvic irradiation of 10 MV x-ray was carried out in 15 fractions of 2 Gy daily, with a total dose of 30 Gy, and intracavitary radium insertion with a total dose of 960 mg hours (20 mg x 48 hour). She had been followed-up in our department since 1972, when rectal bleeding occurred. Proctoscopy and periodical biopsies were performed when the patient visited our hospital. There was no evidence of malignant tumor cells nor of recurrent cervical cancer from 1973 to 1989. In August, 1990, a biopsy specimen taken from a rectal ulcer revealed a malignant mucinous adenocarcinoma. The time interval between the radiotherapy and the development of the rectal cancer was 19 years. Microscopically, the main lesion was situated in the granulation tissue covered with the regenerating mucosal epithelium, and histologically was found to be a mucinous adenocarcinoma. Other radiation damage was additionally found including colitis, endarteritis and intestinal wall fibrosis. The evidence strongly suggested the present case to be one of radiation-induced rectal cancer. (author)

    An automated system for registration of tail bleeding in rats using a camera and a user-designed PC-based software program has been developed. The live and processed images are displayed on the screen and are exported together with a text file for later statistical processing of the data allowing calculation of e.g. number of bleeding episodes, bleeding times and bleeding areas. Proof-of-principle was achieved when the camera captured the blood stream after infusion of rat whole blood into saline. Suitability was assessed by recording of bleeding profiles in heparin-treated rats, demonstrating that the system was able to capture on/off bleedings and that the data transfer and analysis were conducted successfully. Then, bleeding profiles were visually recorded by two independent observers simultaneously with the automated recordings after tail transection in untreated rats. Linear relationships were found in the number of bleedings, demonstrating, however, a statistically significant difference in the recording of bleeding episodes between observers. Also, the bleeding time was longer for visual compared to automated recording. No correlation was found between blood loss and bleeding time in untreated rats, but in heparinized rats a correlation was suggested. Finally, the blood loss correlated with the automated recording of bleeding area. In conclusion, the automated system has proven suitable for replacing visual recordings of tail bleedings in rats. Inter-observer differences can be eliminated, monotonous repetitive work avoided, and a higher through-put of animals in less time achieved. The automated system will lead to an increased understanding of the nature of bleeding following tail transection in different rodent models.

    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

    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.

    Enteric duplication is a rare developmental malformation in people, dogs and cats. The purpose of the present report is to describe the first case of a rectal duplication cyst in a 7-year-old domestic shorthair cat presenting for acute constipation and tenesmus. On rectal palpation a spherical mass compressing the lumen of the rectum could be felt in the dorsal wall of the rectum. A computed tomography (CT) scan confirmed the presence of a well demarcated cystic lesion in the pelvic canal, dorsal to the rectum. The cyst was surgically removed via a perineal approach. No communication with the rectal lumen could be demonstrated. Histopathological examination was consistent with a rectal duplication cyst. Clinical signs resolved completely after excision of this conjoined non-communicating cystic rectal duplicate. Copyright © 2010 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

    the RFB. In some cases, RFBs can create a vacuum effect for which Foley catheters may be used to break the seal and provide additional traction. After the lubricated Foley passes proximal to the RFB and the balloon is inflated, gentle traction should be employed to move the object closer. Sedation can also be employed to decrease rectal tone and make the procedure more tolerable for the patient. Complications prior to or during removal of the RFB include tearing of the rectal mucosa, perforation, infection, fecal incontinence, bladder and vessel injury or migration of the RFB to the chest wall.3,5 Uncontrollable rectal bleeding, peritonitis, or perforation are contraindications to ED RFB removal and warrant surgery or gastroenterology consultation. General anesthesia can be used for laparotomy with single incision to remove RFBs in the operating room.2 In this case, procedural sedation was utilized to facilitate removal of the object. Ketamine (2 mg/kg intravenously was initially proposed, but due to concerns of the patient’s history of drug abuse, alternatives were considered. While Ketamine is generally well-tolerated, the incidence of dysphoric reactions has been estimated to occur in 10%-20% of patients.6 There is also some evidence that patients with a history of drug abuse may be more likely to have tolerance to Ketamine that requires higher dosing.7 Taking these factors into account, Etomidate (0.2 mg/kg intravenously was used instead with favorable results. A metallic flashlight was removed by grasping the object with a combination of forceps and manual manipulation. After RFB removal, sigmoidoscopy was recommended to assess for rectal mucosal injuries or tears.8 No additional injuries were found on sigmoidoscopy and the patient tolerated the procedure well without complications.

  14. A Source-Term Based Boundary Layer Bleed/Effusion Model for Passive Shock Control

    Baurle, Robert A.; Norris, Andrew T.

    2011-01-01

    A modeling framework for boundary layer effusion has been developed based on the use of source (or sink) terms instead of the usual practice of specifying bleed directly as a boundary condition. This framework allows the surface boundary condition (i.e. isothermal wall, adiabatic wall, slip wall, etc.) to remain unaltered in the presence of bleed. This approach also lends itself to easily permit the addition of empirical models for second order effects that are not easily accounted for by simply defining effective transpiration values. Two effusion models formulated for supersonic flows have been implemented into this framework; the Doerffer/Bohning law and the Slater formulation. These models were applied to unit problems that contain key aspects of the flow physics applicable to bleed systems designed for hypersonic air-breathing propulsion systems. The ability of each model to predict bulk bleed properties was assessed, as well as the response of the boundary layer as it passes through and downstream of a porous bleed system. The model assessment was performed with and without the presence of shock waves. Three-dimensional CFD simulations that included the geometric details of the porous plate bleed systems were also carried out to supplement the experimental data, and provide additional insights into the bleed flow physics. Overall, both bleed formulations fared well for the tests performed in this study. However, the sample of test problems considered in this effort was not large enough to permit a comprehensive validation of the models.

    Full Text Available Skin fat biopsy of the abdominal wall is a simple and safe method for detecting amyloidosis, and rectal mucosal biopsy is also frequently used for screening for the disease; however, the sensitivity of these approaches has not been fully studied. The aim of this study was to evaluate the efficacy of skin fat biopsy combined with rectal mucosal biopsy as a screening procedure for the diagnosis of systemic immunoglobulin light-chain (AL amyloidosis.We retrospectively analyzed 224 AL amyloidosis patients confirmed by renal biopsy, including a test group of 165 patients and validation group of 59 patients. Surgical skin fat biopsy from the abdominal wall and rectal mucosal biopsy under endoscopy was performed to obtain specimens. Congo red staining and immunofluorescence staining with antibodies against light chains were performed to type the disease. Pathology reports were reviewed to assess the diagnostic sensitivity of skin fat biopsy and rectal mucosal biopsy. Diagnostic specificity was not examined in the present study, because no healthy volunteers and only few patients with other diseases had performed immunofluorescence staining on skin fat and rectal specimens.Of the 165 patients in the test group, Congo red staining of skin fat and rectal mucosal specimens was associated with a sensitivity of 89.3% and 94.8%, respectively. The sensitivity increased to 98.9% by combining both biopsy methods. Immunofluorescence stains were positive in 81.1% of patients undergoing skin fat biopsy and 84.7% of patients undergoing rectal mucosal biopsy. Immunofluorescence stains yielded positive results in 86.7% of cases combining skin fat biopsy with rectal mucosal biopsy. The diagnostic results also performed well in the validation group.Surgical skin biopsy including the subcutaneous fat pad can be performed safely at the bedside and is useful for diagnosing AL amyloidosis. Combining skin fat biopsy with rectal mucosal biopsy may identify amyloid deposits in

    The dramatic improvement in local control of rectal cancer observed during the last decades is to be attributed to attention to surgical technique and to the introduction of neoadjuvant therapy regimens. Nevertheless, systemic relapse remains frequent and is currently insufficiently addressed. Intensification of neoadjuvant therapy by incorporating chemotherapy with or without targeted agents before the start of (chemo)radiation or during the waiting period to surgery may present an opportunity to improve overall survival. An increasing number of patients can nowadays undergo sphincter preserving surgery. In selected patients, local excision or even a “wait and see” approach may be feasible following active neoadjuvant therapy. Molecular and genetic biomarkers as well as innovative imaging techniques may in the future allow better selection of patients for this treatment option. Controversy persists concerning the selection of patients for adjuvant chemotherapy and/or targeted therapy after neoadjuvant regimens. The currently available evidence suggests that in complete pathological responders long-term outcome is excellent and adjuvant therapy may be omitted. The results of ongoing trials will help to establish the ideal tailored approach in resectable rectal cancer. PMID:22970381

  17. Studies of GI bleeding with scintigraphy and the influence of vasopressin

    The management of patients with gastrointestinal (GI) bleeding depends on accurate localization of the site of hemorrhage. Endoscopy and arteriography, although successful in achieving this goal in the majority of patients, are invasive and have other shortcomings. The introduction of the 99mTc-sulfur colloid technique has greatly simplified the evaluation and management of these patients. This test is useful in detecting and localizing the bleeding site in the lower GI tract. Scintigraphy is now used as the initial study of choice in patients with rectal bleeding. Advances made in angiography and nuclear medicine techniques also have resulted in improved management of patients. Conservative approaches succeed in controlling hemorrhage in most patients. Vasopressin is the most widely tested agent and has been adopted by many as the preferred preparation for this purpose. Before the introduction of the 99mTc-sulfur colloid technique, angiography was used to monitor the effectiveness of this drug, whether administered intravenously or intraarterially. With the use of scintigraphy and intravenous administration of vasopressin, these patients now can be managed noninvasively. Only when the intravenous Pitressin infusion fails to stop hemorrhage, is the intraarterial approach considered. Surgery is used as a last resort when these measures fail to stop the bleeding

    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.

    Full Text Available Leptospirosis is a globally widespread zoonotic infection caused by leptospira-type spirochetes. In humans the infection generally occurs by way of direct or indirect contact with infected animal urine. The main clinical symptoms are fever, septicemia, headache, fatigue and myalgia. The disease usually begins with a high fever. The largest risk factor for leptospirosis is occupational and it includes farmers, ranchers, military personnel and, sewer workers. There is also a risk through recreational exposure such as freshwater swimming and kayaking. This report describes a case of leptospirosis following a course with hyper-pyrexia, for the first time in the medical literature. [Dis Mol Med 2016; 4(2.000: 18-20

    Using Iridium-192 wires through a rectal template after Syed, interstitial brachytherapy was conducted in a patient with inoperable adenocarcinoma of the rectum. 67-year-old man with constipation and change in the stool caliber underwent external radiotherapy (4,000cGy/4W) to the whole pelvis including the perineum, followed by interstitial implant using a template, at the Department of Radiology, Osaka University Hospital. Marked tumor regression, marked circumferential fibrosis and a remarkable decline of CEA titers (pre-RT: 35.8ng/ml, post-RT: 6.2ng/ml) were observed until 7 months post-RT. The domestic production of Iridium-192 wires has made possible the intergrated use of brachytherapy in the perineal region in Japan. (author)

    High-resolution MRI is the best method of assessing the relation of the rectal tumor with the potential circumferential resection margin (CRM). Therefore it is currently considered the method of choice for local staging of rectal cancer. The primary surgery of rectal cancer is total mesorectal excision (TME), which plane of dissection is formed by the mesorectal fascia surrounding mesorectal fat and rectum. This fascia will determine the circumferential margin of resection. At the same time, high resolution MRI allows adequate pre-operative identification of important prognostic risk factors, improving the selection and indication of therapy for each patient. This information includes, besides the circumferential margin of resection, tumor and lymph node staging, extramural vascular invasion and the description of lower rectal tumors. All these should be described in detail in the report, being part of the discussion in the multidisciplinary team, the place where the decisions involving the patient with rectal cancer will take place. The aim of this study is to provide the information necessary to understand the use of high resolution MRI in the identification of prognostic risk factors in rectal cancer. The technical requirements and standardized report for this study will be describe, as well as the anatomical landmarks of importance for the total mesorectal excision (TME), as we have said is the surgery of choice for rectal cancer.

    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.

    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.

In patients with CKD who are not receiving dialysis, lower renal function is associated with higher risk for upper gastrointestinal bleeding.

    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.

    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

    To evaluate the outcome of stapled versus sutured colo-rectal anastomosis after low anterior resection of mid-rectal carcinoma. A prospective study of fifty patients who underwent colo-rectal anastomosis following low anterior resection (LAR) of T2 mid-rectal cancers at the Egyptian National Cancer Institute during the time period from June 2010 to June 2013 was conducted. Classification was into two groups; a stapled anastomosis group I (25 patients) and a hand-sewn anastomosis group II (25 patients). All operations are evaluated regarding intra-operative complications such as anastomotic line bleeding, visceral injuries or major blood loss. The anastomotic time and operative time are documented for each operation. All patients are evaluated post-operatively for anastomotic leakage (AL), wound infection and ileus. The distance of the tumor from the anal verge was 9.6 ± 2.0 cm in group I and 9.9 ± 2.4 cm in group II. The mean operative time was 191.5 ± 16.2 min in the stapled group and 208 ± 18.6 min in the sutured group (p=0.002). The mean anastomotic times were 9.0 ± 1.9 min and 19.7 ± 12.2 min (p=0.001). Anastomotic leakage developed in three (12.0%) patients in the stapled group and in four (16.0%) patients in the sutured group (p=1.000). Post-operative ileus was observed in 3 patients in group I and one patient in group II. Wound infection developed in three (12.0%) patients in the stapled group and four (16.0%) patients in the sutured group (p=1.000). Colo-rectal anastomosis after low anterior resection for mid rectal carcinoma can be conducted safely either by stapling or hand-sewn techniques; however the stapling technique showed shorter anastomotic and operative times with no significant advantages regarding intra- or post-operative complications or hospital stay.

  12. Management of acute gastric varices bleeding

    Full Text Available Gastroesophageal varices bleeding is a major complication in patients with cirrhosis. Gastric varices (GVs occur in approximately 20% of patients with portal hypertension. However, GV bleeding develops in only 25% of patients with GV and requires more transfusion and has higher mortality than esophageal variceal (EV bleeding. The best strategy for managing acute GV bleeding is similar to that of acute EV bleeding, which involves airway protection, hemodynamic stabilization, and intensive care. Blood transfusion should be cautiously administered in order to avoid rebleeding. Vasoactive agents such as terlipressin or somatostatin should be used when GV bleeding is suspected. Routine use of prophylactic antibiotics reduces bacterial infection and lowers rebleeding rates. By administering endoscopic cyanoacrylate injection, the initial hemostasis rate achieved is at least 90% in most cases; the average mortality rate of GV bleeding is approximately 10–30% and the rebleeding rate is between 22% and 37%. Although endoscopic injection of cyanoacrylate is superior to sclerotherapy and band ligation, and has remained the treatment of choice for treating acute GV bleeding, the outcome of this treatment is still unsatisfactory. New treatment options, such as thrombin injection, transjugular intrahepatic portosystemic shunts, or balloon-occluded retrograde transvenous obliteration, have shown promising results for acute GV bleeding. However, randomized controlled trials are needed to compare the efficacy of these therapies with cyanoacrylate.

    A retrospective review of 80 scintigraphic bleeding studies performed with Tc-99m sulfur colloid or Tc-99m labeled red blood cells showed five cases where there were abnormal findings not related to bleeding. In some cases, the abnormalities were initially confused with bleeding or could obscure an area of bleeding, while in other cases, the abnormalities represented additional clinical information. These included bone marrow replacement related to tumor and radiation therapy, hyperemia related to a uterine leiomyoma and a diverticular abscess, and a dilated abdominal aorta (aneurysm). Recognition of such abnormalities should prevent an erroneous diagnosis and the additional information may be of clinical value

    As the use of compressed air in industrial work has increased, so has the risk of associated pneumatic injury from its improper use. However, damage of large intestine caused by compressed air is uncommon. Herein a case of pneumatic rupture of the rectum is described. The patient was admitted to the Emergency Room complaining of abdominal pain and distension. His colleague triggered a compressed air nozzle over his buttock. On arrival, vital signs were stable but physical examination revealed peritoneal irritation and marked distension of the abdomen. Computed tomography showed a large volume of air in the peritoneal cavity and subcutaneous emphysema at the perineum. A rectal perforation was found at laparotomy and the Hartmann procedure was performed.

  16. Radiotherapy for early rectal cancer

    A literature review of 10 series using electrocoagulation, fulguration, or local excision demonstrates that about 70% of all patients had tumors smaller than 3 cm and the remainder had tumors measuring between 4 cm and 7 cm. Although primary tumor size in rectal cancer has little prognostic value per se, it is obviously important when determining the appropriateness of local therapy. Selecting patients for local therapy based on tumor size alone seems reasonable, since the recurrence and survival rates for the patients are similar to those achieved with radical surgery. Since patients treated with local excision alone have predominantly T1 or T2 tumors, a comparison with the data of others illustrates the prognostic utility of the degree of bowel penetration and shows five-year survival rates of 71% to 76% for patients with limited disease. In this chapter, the author describes an additional group of patients who also did well following postoperative radiotherapy after conservative surgical treatment

    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...

    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

    The differentiation between constipation due to rectal inertia and that due to outlet obstruction from non-relaxing puborectalis muscle (PRM) is problematic and not easily achieved with one diagnostic test. Therefore, we studied the hypothesis that the rectal cooling test (RCT) can effectively be used to differentiate between those two forms of constipation. The study enrolled 28 patients with constipation and abnormal transit study in whom radio-opaque markers accumulated in the rectum; 15 healthy volunteers acted as controls. Electromyographic activity of the external anal sphincter (EAS) and PRM was initially recorded. Subsequently rectal wall tone was assessed by a barostat system during rectal infusion with normal saline at 30 degrees C and at 4 degrees C with simultaneous electromyography (EMG). There was a significant increase in EMG activity of the EAS and PRM on strain- ing (panismus, in 10 of 28 patients and 0 of 15 controls. Rectal tone in controls did not respond to saline infusion at 30 degrees C, but it increased at 4 degrees C (panismus (panismus while it had no effect in the remaining patients. Lack of increase of rectal tone may be secondary to rectal inertia. According to these preliminary observations, the rectal cooling test may be useful in differentiating between rectal inertia and anismus.

    Staging of rectal carcinoma before surgical treatment was performed in a prospective blind study, comparing digital rectal exploration and transrectal linear ultrasonography (TRUS) with the resulting pathological examination. TRUS underestimated depth of penetration in 3 of 33 patients...... and overestimation resulted in 9 of 74. The figures for digital examination were 5 of 18 and 20 of 76, respectively. Penetration of the rectal wall was correctly identified in 56 of 61 patients by digital examination and in 59 of 61 by TRUS. Specimens without penetration of the rectal wall were identified in 26...

    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 50 . Anal wall DVHs were used for fecal incontinence, whereas anorectal wall dose best described the other two endpoints. Conclusions

    Abstract Vitamin K antagonists (VKA) have shown to be effective in primary and secondary prevention of thromboembolism, but the associated risk of bleeding is an important limitation. The majority of the bleeds are clinically mild. In this study, we assessed whether these minor bleeds are associated with major bleeding, when controlling for other important risk indicators, including the achieved quality of anticoagulation. For this, 5898 patients of a specialised anticoagulation cl...

    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.

    To characterize menstrual bleeding patterns and treatment of heavy menstrual bleeding in adolescents with bleeding disorders. We conducted a retrospective review of female patients aged nine to 21 years with known bleeding disorders who attended a pediatric gynecology, hematology, and comprehensive hematology/gynecology clinic at a children's hospital in a metropolitan area. Prevalence of heavy menstrual bleeding at menarche, prolonged menses, and irregular menses among girls with bleeding disorders and patterns of initial and subsequent treatment for heavy menstrual bleeding in girls with bleeding disorders. Of 115 participants aged nine to 21 years with known bleeding disorders, 102 were included in the final analysis. Of the 69 postmenarcheal girls, almost half (32/69, 46.4%) noted heavy menstrual bleeding at menarche. Girls with von Willebrand disease were more likely to have menses lasting longer than seven days. Only 28% of girls had discussed a treatment plan for heavy menstrual bleeding before menarche. Hormonal therapy was most commonly used as initial treatment of heavy menstrual bleeding. Half (53%) of the girls failed initial treatment. Combination (hormonal and non-hormonal therapy) was more frequently used for subsequent treatment. Adolescents with bleeding disorders are at risk of heavy bleeding at and after menarche. Consultation with a pediatric gynecologist and/or hematologist prior to menarche may be helpful to outline abnormal patterns of menstrual bleeding and to discuss options of treatment in the event of heavy menstrual bleeding.

    In early epidemiological studies of diet and cancer the stress was on the search for causal factors. Population (ecological) studies tended to show a strong correlation between meat intake, particularly red meat, and the risk of colo-rectal cancer. They also tended to show meat to be strongly inversely correlated with cancers of the stomach and oesophagus and liver. Early case-control studies tended to support the postulated role for red meat in colo-rectal carcinogenesis, although more recent case-control studies, particularly those from Europe, have tended to show no relationship. The cohort studies in general failed to detect any relationship between meat intake and colo-rectal cancer risk. The available evidence points to the intake of protective factors such as vegetables and whole-grain cereals being the main determinants of colo-rectal cancer risk, with meat intake only coincidentally related.

    Pelvic floor and rectal prolapse conditions have greatly benefited by new imaging and instrumental diagnostic approaches, and especially defecography, for both pathophysiological interpretation and differential diagnosis. The authors investigated the efficacy of defecography in the assessment of rectal prolapse, and in particular the role of videproctography in diagnosis such dynamic disorders. The dynamic changes of ampulla are well depicted by videoproctography, which showed anorectum normalization and spontaneous reduction of invagination after intussusception. Defecography exhibited good capabilities in showing rectal wall function abnormalities. Finally, some features of videoproctography such as low radiation dose, non-invasiveness and ease of execution, make the examination acceptable to patients with anorectal disorders and for the follow-up of rectal prolapse [it

    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. (author)

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.

    To evaluate the feasibility and safety of endoscopic submucosal dissection (ESD) for lower rectal lesions with hemorrhoids. The outcome of ESD for 23 lesions with hemorrhoids (hemorrhoid group) was compared with that of 48 lesions without hemorrhoids extending to the dentate line (non-hemorrhoid group) during the same study period. Median operation times (ranges) in the hemorrhoid and non-hemorrhoid groups were 121 (51-390) and 130 (28-540) min. The en bloc resection rate and the curative resection rate in the hemorrhoid group were 96% and 83%, and they were 100% and 90% in the non-hemorrhoid group, respectively. In terms of adverse events, perforation and postoperative bleeding did not occur in both groups. In terms of the clinical course of hemorrhoids after ESD, the rate of complete recovery of hemorrhoids after ESD in lesions with resection of more than 90% was significantly higher than that in lesions with resection of less than 90%. ESD on lower rectal lesions with hemorrhoids could be performed safely, similarly to that on rectal lesions extending to the dentate line without hemorrhoids. In addition, all hemorrhoids after ESD improved to various degrees, depending on the resection range.

    Aim Heterotopic gastric mucosa is a well-known congenital anomaly in Meckel's diverticula and duplication cysts. Solitary heterotopic gastric mucosa in the rectum is a rare and frequently overlooked abnormality. Starting from a patient history, the literature is searched and all cases reported over the past 20 years are reviewed and compared to a summary of the older cases. Differences between adult and childhood presentation are outlined and our patient is compared with prior reported cases. Case A 3-year-old girl presented with recurrent rectal blood loss caused by heterotopic gastric mucosa without duplication cyst. She was endoscopically treated with two-stage endoscopic surgical dissection (ESD). Up to now, rectal heterotopic gastric mucosa has been reported in 34 adults and 24 children, including this patient. There is an overall male dominance (69%). Presenting complaints in children were recurrent fresh blood loss per anum (96%), pain (46%), perineal ulcers (25%), diarrhoea (8%) and one patient had an ano-cutaneous fistula. Endoscopy revealed a mucosal elevation with a slightly different aspect (33%), a polyp (42%) and a solitary ulcer (25%). Endoscopy in adults reveals more frequently polyps compared to children. Treatment in childhood is mainly surgical where adults are more frequently treated with endoscopic techniques. Conclusion In a child with recurrent rectal bleeding in good general health, it is important to withhold heterotopic gastric mucosa in the differential diagnosis and take sufficient biopsies during endoscopy. © Acta Gastro-Enterologica Belgica.

    This study evaluated the early results (with particular reference to complications) of stapled transanal rectal resection (STARR) carried out using the CCS-30 Contour® Transtar™ device. The procedure was performed in a single centre on patients with obstucted defecation caused by rectocele or rectal intussusception. From July 2007 to February 2009, 133 patients were treated. Preoperatively, all underwent clinical examination, transanal ultrasonography, anorectal manometry and cinedefaecography. Obstructed defaecation syndrome was assessed using the Cleveland Clinic Constipation Score (CCC-S). Early postoperative complications and those occurring within 6 months were recorded. The median follow-up period was 19 (range 12-30) months. The mean ± standard deviation preoperative CCC-S of 19.4 ± 7.1 decreased to 10.1 ± 9.0 postoperatively. The early complication rate was 15.7% and included rectovaginal fistula (n = 1), rectal perforation (n = 1), posterior dehiscence (n = 4), further surgery for retained staples (n = 2), postoperative bleeding (n = 2) and postoperative impaired continence (n = 11). STARR using the Contour Transtar device seems to be effective for treating obstructed defaecation. However, serious complications may occur. © 2011 The Authors.

  1. Appendiceal Adenocarcinoma Presenting as a Rectal Polyp

    2016-02-01

    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

    The authors present an anterior rectal cyst in a 14-month-old girl. This rare variant of rectal duplications presented with recurrent urinary infections. The diagnosis was challenging in view of the multiple differential diagnoses to be considered. Magnetic resonance imaging appeared to be the most accurate preoperative investigation. The cyst was removed uneventfully by partial excision and mucosal ablation. An awareness of this variant can lead to early diagnosis and curative resection.

    Rectal cancer and its treatment impair survivors' productivity. To assess determinants of market and nonmarket employment, job search, volunteering, and homemaking among survivors five years or longer after diagnosis. We mailed questionnaires to 1063 survivors who were members of Kaiser Permanente (Northern California, Northwest) during 2010 and 2011. Productive activities, functional health status, and bowel management at the time of the survey. Response rate was 60.5% (577/953). Higher comorbidity burdens were associated with lower productivity for men and women rectal cancer survivors. Productive survivors were younger and had lower disease stage and age at diagnosis, higher household income and educational attainment, and fewer comorbidity burdens and workplace adjustments than did nonproductive survivors (p < 0.05 each; 2-sided). Productive rectal cancer survivors were evenly split by sex. Staying productive is associated with better mental health for rectal cancer survivors. Rectal cancer survivors with multiple chronic conditions, higher disease stage, lower productive activities, and older age need better access to medical care and closer monitoring of the quality of their care, including self-care. To capture the full extent of the involvement of survivors in all types of productive activities, research should routinely include measures of employment, searching for employment, homemaking, and volunteering. Counting market and nonmarket productive activities is innovative and recognizes the continuum of contributions survivors make to families and society. Health care systems should routinely monitor rectal cancer survivors' medical care access, comorbidities, health-related quality of life, and productive activities.

    To evaluate the accuracy of preoperative staging of rectal cancer by transrectal US(7.5MHz linear array transducer), 17 cases with primary rectal cancer who were examined by transrectal US and histopathologically proven, were analyzed. We correlated the sonographic features of the depth of rectal wall invasion, perirectal fat infiltration and perirectal lymph node metastasis with histopathologic findings. The tumor staging was analyzed according to the TNM classification. The depth of rectal wall invasion was in accordance with histopathologic findings in 15 of 17 cases (accuracy:88.2%). The sensitivity and specificity of transrectal US in predicting perirectal lymph node metastasis were 20% and 75%, respectively (accuracy : 58.8%). The sensitivity and specificity in predicting perirectal fat infiltration were 92.9% and 100%, respectively (accuracy : 94%). Perirectal fat infiltration and depth of rectal wall invasion were preoperatively diagnosed with relatively high accuracy, while perirectal lymph node metastasis with low accuracy. In conclusion, transrectal US is a useful imaging modality for preoperative staging of rectal cancer

    Purpose: To develop a method of analyzing rectal surface area irradiated and rectal complications in prostate conformal radiotherapy. Methods and Materials: Dose-surface histograms of the rectum, which state the rectal surface area irradiated to any given dose, were calculated for a group of 27 patients treated with a four-field box technique to a total (tumor minimum) dose ranging from 68 to 70 Gy. Occurrences of rectal toxicities as defined by the Radiation Therapy Oncology Group (RTOG) were recorded and examined in terms of dose and rectal surface area irradiated. For a specified end point of rectal complication, the complication probability was analyzed as a function of dose irradiated to a fixed rectal area, and as a function of area receiving a fixed dose. Lyman's model of normal tissue complication probability (NTCP) was used to fit the data. Results: The observed occurrences of rectal complications appear to depend on the rectal surface area irradiated to a given dose level. The patient distribution of each toxicity grade exhibits a maximum as a function of percentage surface area irradiated, and the maximum moves to higher values of percentage surface area as the toxicity grade increases. The dependence of the NTCP for the specified end point on dose and percentage surface area irradiated was fitted to Lyman's NTCP model with a set of parameters. The curvature of the NTCP as a function of the surface area suggests that the rectum is a parallel structured organ. Conclusions: The described method of analyzing rectal surface area irradiated yields interesting insight into understanding rectal complications in prostate conformal radiotherapy. Application of the method to a larger patient data set has the potential to facilitate the construction of a full dose-surface-complication relationship, which would be most useful in guiding clinical practice

    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.)

    Observational studies have consistently shown an increased risk of upper gastrointestinal bleeding in users of selective serotonin receptor inhibitors (SSRIs), probably explained by their inhibition of platelet aggregation. Therefore, treatment with SSRIs is often temporarily withheld in patients with peptic ulcer bleeding. However, abrupt discontinuation of SSRIs is associated with development of withdrawal symptoms in one-third of patients. Further data are needed to clarify whether treatment with SSRIs is associated with poor outcomes, which would support temporary discontinuation of treatment. To identify if treatment with SSRIs is associated with increased risk of: (1) endoscopy-refractory bleeding, (2) rebleeding or (3) 30-day mortality due to peptic ulcer bleeding. A nationwide cohort study. Analyses were performed on prospectively collected data on consecutive patients admitted to hospital with peptic ulcer bleeding in Denmark in the period 2006-2014. Logistic regression analyses were used to investigate the association between treatment with SSRIs and outcome following adjustment for pre-defined confounders. Sensitivity and subgroup analyses were performed to evaluate the validity of the findings. A total of 14 343 patients were included. Following adjustment, treatment with SSRIs was not associated with increased risk of endoscopy-refractory bleeding (odds ratio [OR] [95% Confidence Interval (CI)]: 1.03 [0.79-1.33]), rebleeding (OR [95% CI]: 0.96 [0.83-1.11]) or 30-day mortality (OR [95% CI]: 1.01 [0.85-1.19]. These findings were supported by sensitivity and subgroup analyses. According to our data, treatment with SSRIs does not influence the risk of endoscopy-refractory bleeding, rebleeding or 30-day mortality in peptic ulcer bleeding. © 2017 John Wiley & Sons Ltd.

    Many studies have been performed to assess correlations between measures derived from dose-volume histograms and late rectal toxicities for radiotherapy of prostate cancer. The purpose of this study was to quantify correlations between measures describing the shape and location of the dose distribution and different outcomes. The dose to the rectal wall was projected on a two-dimensional map. In order to characterize the dose distribution, its centre of mass, longitudinal and lateral extent, and eccentricity were calculated at different dose levels. Furthermore, the dose-surface histogram (DSH) was determined. Correlations between these measures and seven clinically relevant rectal-toxicity endpoints were quantified by maximally selected standardized Wilcoxon rank statistics. The analysis was performed using data from the RT01 prostate radiotherapy trial. For some endpoints, the shape of the dose distribution is more strongly correlated with the outcome than simple DSHs. Rectal bleeding was most strongly correlated with the lateral extent of the dose distribution. For loose stools, the strongest correlations were found for longitudinal extent; proctitis was most strongly correlated with DSH. For the other endpoints no statistically significant correlations could be found. The strengths of the correlations between the shape of the dose distribution and outcome differed considerably between the different endpoints. Due to these significant correlations, it is desirable to use shape-based tools in order to assess the quality of a dose distribution.

    Shen, Zhanlong; Ye, Yingjiang; Wang, Shan

    2017-07-25

    Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding. Familiarity with the specific anatomical planes and landmarks plays an important role in shortening the learning curve, decreasing the complications, increasing the success rate of operation and standardization of taTME.

  13. Is palliative resection of the primary tumour, in the presence of advanced rectal cancer, a safe and useful technique for symptom control?

    Al-Sanea, N.; Isbister, W.H.

    2004-01-01

    Over an 8-year period 22 patients (average age 54 years) underwent rectal resectional surgery in the presence of metastatic disease. There were 13 men and nine women. The commonest complaint was rectal bleeding. All patients had chest radiographs. Pulmonary metastases were identified in four patients. Nineteen abdominal and pelvic computed tomography scans were performed and eight showed evidence of metastases. Skeletal radiographs in two patients showed evidence of bone metastasis. At operation, intraperitoneal metastases were found in 18 patients. Nine of these were not identified preoperatively. Six patients underwent abdomino-perineal resection, nine anterior resection and seven a Hartmann's procedure. Eight patients developed a significant postoperative complication and one died 42 days after surgery. The mean length of hospital stay was 18.6 days. Nine patients received preoperative radiotherapy. Four patients had palliative radiotherapy, two for bony, one for liver and one for peritoneal metastases. Patients were followed up for a mean of 1.1 years. During follow up, 11 returned to the emergency room on 24 occasions. Two patients required readmission. No patient had further rectal bleeding. The mean survival was 1.3 years. It is concluded that patients with rectal cancer and unresectable distant metastases can be successfully palliated by resection of the primary tumour with low morbidity and mortality. The early involvement of a palliative care team facilitates patient management and helps patients enjoy what remains of the rest of their lives at home, in comfort and with good symptom control.

    Several treatments have been proven to be effective for variceal bleeding in patients with cirrhosis. The aim of this multicenter, prospective, cohort study was to assess how these treatments are used in clinical practice and what are the posttherapeutic prognosis and prognostic indicators of upper digestive bleeding in patients with cirrhosis. A training set of 291 and a test set of 174 bleeding cirrhotic patients were included. Treatment was according to the preferences of each center and the follow-up period was 6 weeks. Predictive rules for 5-day failure (uncontrolled bleeding, rebleeding, or death) and 6-week mortality were developed by the logistic model in the training set and validated in the test set. Initial treatment controlled bleeding in 90% of patients, including vasoactive drugs in 27%, endoscopic therapy in 10%, combined (endoscopic and vasoactive) in 45%, balloon tamponade alone in 1%, and none in 17%. The 5-day failure rate was 13%, 6-week rebleeding was 17%, and mortality was 20%. Corresponding findings for variceal versus nonvariceal bleeding were 15% versus 7% (P =.034), 19% versus 10% (P =.019), and 20% versus 15% (P =.22). Active bleeding on endoscopy, hematocrit levels, aminotransferase levels, Child-Pugh class, and portal vein thrombosis were significant predictors of 5-day failure; alcohol-induced etiology, bilirubin, albumin, encephalopathy, and hepatocarcinoma were predictors of 6-week mortality. Prognostic reassessment including blood transfusions improved the predictive accuracy. All the developed prognostic models were superior to the Child-Pugh score. In conclusion, prognosis of digestive bleeding in cirrhosis has much improved over the past 2 decades. Initial treatment stops bleeding in 90% of patients. Accurate predictive rules are provided for early recognition of high-risk patients.

  17. Non-Local Sparse Image Inpainting for Document Bleed-Through Removal

    Full Text Available Bleed-through is a frequent, pervasive degradation in ancient manuscripts, which is caused by ink seeped from the opposite side of the sheet. Bleed-through, appearing as an extra interfering text, hinders document readability and makes it difficult to decipher the information contents. Digital image restoration techniques have been successfully employed to remove or significantly reduce this distortion. This paper proposes a two-step restoration method for documents affected by bleed-through, exploiting information from the recto and verso images. First, the bleed-through pixels are identified, based on a non-stationary, linear model of the two texts overlapped in the recto-verso pair. In the second step, a dictionary learning-based sparse image inpainting technique, with non-local patch grouping, is used to reconstruct the bleed-through-contaminated image information. An overcomplete sparse dictionary is learned from the bleed-through-free image patches, which is then used to estimate a befitting fill-in for the identified bleed-through pixels. The non-local patch similarity is employed in the sparse reconstruction of each patch, to enforce the local similarity. Thanks to the intrinsic image sparsity and non-local patch similarity, the natural texture of the background is well reproduced in the bleed-through areas, and even a possible overestimation of the bleed through pixels is effectively corrected, so that the original appearance of the document is preserved. We evaluate the performance of the proposed method on the images of a popular database of ancient documents, and the results validate the performance of the proposed method compared to the state of the art.

    Thirty-five patients with low-lying rectal adenocarcinoma have been treated with intra-cavitary radiation (Papillon's technique). Twenty-three were treated for cure and 12 for palliation. The indications for curative intracavity radiation were mobile polypoid tumors, less than 3 cm in diameter, with Broder's Grades 1 and 2 differentiation lying less than 11 cm from the anal verge. Doses between 2000 and 4000 cGy were delivered to a total of 7000 to 20000 cGy with complete resolution of the tumors. Eighty-seven per cent in the curative group are alive and well up to 42 months after treatment with a minimum follow-up of six months. Of the 23 patients treated for cure, three patients had recurrences within 18 months of therapy. Two of the three patients are alive following surgery. The third patient died in the postoperative period. The results of intracavitary radiation are comparable to ablative surgery and avoid a permanent colostomy. Age, frailty, or other medical conditions do not preclude this treatment. Anesthesia and hospitalization are not required. This method can also be used for palliation of recurrent tumors and in patients who are unsuitable for surgery.

    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

    Following preoperative chemoradiation and surgery, many patients with stage II to III rectal cancer are unable to tolerate full-dose adjuvant chemotherapy. BrUOG R-224 was designed to assess the impact of COmplete Neoadjuvant Treatment for REctal cancer (CONTRE), primary chemotherapy followed by chemoradiation and surgery, on treatment delivery, toxicities, and pathologic response at surgery. Patients with clinical stage II to III (T3 to T4 and/or N1 to N2) rectal cancer received 8 cycles of modified FOLFOX6 followed by capecitabine 825 mg/m bid concurrent with 50.4 Gy intensity-modulated radiation therapy. Surgery was performed 6 to 10 weeks after chemoradiation. Thirty-nine patients were enrolled between August 2010 and June 2013. Median age was 61 years (30 to 79 y); 7 patients (18%) were clinical stage II and 32 (82%) stage III. Thirty-six patients (92%) received all 8 cycles of mFOLFOX6, of whom 35 completed subsequent chemoradiation; thus 89% of patients received CONTRE as planned. No unexpected toxicities were reported. All patients had resolution of bleeding and improvement of obstructive symptoms, with no complications requiring surgical intervention. Pathologic complete response (ypT0N0) was demonstrated in 13 patients (33%; 95% CI, 18.24%-47.76%). CONTRE seems to be a well-tolerated alternative to the current standard treatment sequence. Evaluating its impact on long-term outcomes would require a large randomized trial, but using pathologic response as an endpoint, it could serve as a platform for assessing the addition of novel agents to preoperative treatment in stage II to III rectal cancer.

    A permanent colostomy is a serious limitation of the quality of life. Besides cure of cancer, preservation of sphincter function is an important goal of surgery for rectal cancer. In a prospective study a concept offering every patient with rectal cancer either sphincter salvage or a "neosphincter" was investigated, and the impact of this strategy on oncologic results, sphincter function, and quality of life was analyzed. From 1992 to 1997, 276 patients were accepted for the study. Two hundred sixty-one patients had elective surgery, and 15 patients had emergency surgery for their rectal tumors. The postoperative mortality rate was 4 percent. A radical resection (R0) was possible in 197 patients (75 percent). Anterior resection was the most common procedure (n = 87), and intersphincteric resection with coloanal anastomosis was the preferred method for low tumors (n = 65). Abdominoperineal resection was necessary in 15 cases. Thirteen patients had an immediate restoration of sphincter function by means of a dynamic graciloplasty, and 2 patients needed emergency abdominoperineal resection for bleeding. The follow-up was relatively short (median, 36.4 months) at the time of data analysis and showed a local recurrence rate of 8 percent. Although postoperative continence according to the Williams score revealed satisfactory results, subjective quality of life and the scale for specific symptoms showed a significantly worse outcome in patients with ultralow (coloanal) anastomoses compared with those with anterior resection. We conclude that for elective curative surgery of rectal cancer, a permanent colostomy is not necessary provided all presently available techniques of sphincter salvage and restoration are applied. However, the patient has to be informed about possible side effects associated with surgical procedures such as coloanal anastomosis or neosphincter reconstruction, to avoid severe psychological difficulties.

    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.

    Introduction: The reason of high mortality of colorectal carcinoma is above all the fact, that majority of diseases are detected in progressive stage. Radical change in this unfavorable mortality rate can be achieved only by targeted search for early stages of the disease. Early diagnostics consists in rectoscopy and colonoscopy. Regarding X-ray methods it is X-ray irigography. Regarding CT examinations it is CT irigography, virtual colonoscopy. Another examination can be USG examination of abdomen and endo sonographic examination of rectum. Materials and methods: In the period from June 2006 to December 2010, in 60 patients out of the total number 106 examined patients, tumorous affection of rectum CT examination of pelvis and abdomen separately or pelvisand abdomen at one session was made in 3186 patients. In 115 patients we discovered malign tumorous illness of colon. Metastatic affection in the form of distant metastases was proven n 63 patients. 403 patients had CT irigography examination. In 77 out of them we diagnosed colon carcinoma. CT colonoscopy did not discover in our group of 30 patients examined the presence of colon carcinoma. Results: In the group of 60 patients who were diagnosed rectal carcinoma, in 29 patients expansive infiltrative affection was evaluated in endorectal sonography, histologically confirmed in 28 patients - 96,5 %, expansive affection in 41 patients with histological verification in 100 %. With CT we diagnosed 52 expansive tumorous processes, histologically confirmed in 47 patients - 90,38 %. In 63 patients expansive infiltrative process was evaluated, histologically confirmed in 52 patients 82,53 %. In total of 115 examinations there was conformance with histological examination in 99 patients - 86,08 %. In CT irigography we diagnosed colon tumour in 77 patients. Expansive growth was evaluated in 40 patients, histologically confirmed in 37 patients - 92,5 %. Expansive infiltrative expansion was evaluated in 37 patients, with

    To assess the effectiveness and safety of transcatheter arterial embolization for the treatment of massive postpartum bleeding. Transcatheter arterial embolization was attempted in 25 patients with massive postpartum bleeding. After identification at bilateral internal iliac arteriography, the bleeding artery was embolized using gelfoam, polyvinyl alcohol particles or microcoils, and to prevent rebleeding through collateral pathways, the contralateral uterine artery or anterior division of the internal iliac artery was also embolized. Clinical success and complications were retrospectively assessed and documented. Active bleeding foci were detected in 13 patients (52%), and involved the unilateral (n=10) or bilateral (n=2) uterine artery and unilateral vaginal artery (n=1). Twelve (92%) of the 13 patients recovered completely following embolization, but one underwent hysterectomy due to persistent bleeding. The focus of bleeding was not detected in 12 patients (48%), but 11 (92%) of these also recovered following embolization of the bilateral uterine or internal iliac arteries. One patient, however, died due to sepsis. Two of the 12 patients underwent hysterectomy due ro rebleeding on the 12 th and 13 th day, respectively, after embolization. Transcatheter arterial embolization is relatively safe and effective for the treatment massive postpartum bleeding

    Peptic ulcers account for more than half of the cases of non variceal upper gastrointestinal (GI) bleeding and therefore, are the focus of most of the methods of endoscopic hemostasis. Surgical intervention is now largely reserved for patients in whom endoscopic hemostasis has failed. A variety of endoscopic techniques have been employed to stop bleeding and reduce the risk of rebleeding, with no major differences in outcome between these methods. These include injection therapy, fibrin injection, heater probe, mono polar electrocautery, bipolar electrocautery, lasers and mechanical hemo clipping. The most important factor in determining outcome after gastrointestinal bleeding is rebleeding or persistent bleeding. The endoscopic appearance of an ulcer, however, provides the most useful prognostic information for bleeding. Recurrent bleeding after initial endoscopic hemostasis occurs in 15-20% of patients with a bleeding peptic ulcer. The best approach to these patients remains controversial; the current options are repeat endoscopic therapy with the same or a different technique, emergency surgery or semi elective surgery after repeat endoscopic hemostasis. The combination of epinephrine injection with thermal coagulation may be more effective than epinephrine injection alone. Newer modalities such as fibrin injection or the application of hemo clips appear promising and comparative studies are awaited. (author)

    Introduction Hemophilia A displays phenotypic heterogeneity with respect to clinical severity. Aim To determine if tissue factor (TF)-initiated thrombin generation profiles in whole blood in the presence of corn trypsin inhibitor (CTI) are predictive of bleeding risk in hemophilia A. Methods We studied factor(F) VIII deficient individuals (11 mild, 4 moderate and 12 severe) with a well-characterized five-year bleeding history that included hemarthrosis, soft tissue hematoma and annual FVIII concentrate usage. This clinical information was used to generate a bleeding score. The bleeding scores (range 0–32) were separated into three groups (bleeding score groupings: 0, 0 and ≤9.6, >9.6), with the higher bleeding tendency having a higher score. Whole blood collected by phlebotomy and contact pathway suppressed by 100μg/mL CTI was stimulated to react by the addition of 5pM TF. Reactions were quenched at 20min by inhibitors. Thrombin generation, determined by ELISA for thrombin – antithrombin was evaluated in terms of clot time (CT), maximum level (MaxL) and maximum rate (MaxR) and compared to the bleeding score. Results Data are shown as the mean±SD. MaxL was significantly different (phemophilia A. PMID:19563500

    The aim of this study was to assess performance measurement validity of our newly developed robotic surgery task trainer. We hypothesized that residents would exhibit wide variations in their intercohort performance as well as a measurable difference compared to surgeons in fellowship training. Our laboratory synthesized a model of a pelvic tumor that simulates unexpected bleeding. Surgical residents and fellows of varying specialties completed a demographic survey and were allowed 20 minutes to resect the tumor using the da Vinci robot and achieve hemostasis. At a standardized event in the simulation, venous bleeding began, and participants attempted hemostasis using suture ligation. A motion tracking system, using electromagnetic sensors, recorded participants' hand movements. A postparticipation Likert scale survey evaluated participants' assessment of the model's realism and usefulness. Three of the seven residents (postgraduate year 2-5), and the fellow successfully resected the tumor in the allotted time. Residents showed high variability in performance and blood loss (125-700 mL) both within their cohort and compared to the fellow (150 mL blood). All participants rated the model as having high realism and utility for trainees. The results support that our bleeding pelvic tumor simulator has the ability to discriminate resident performance in robotic surgery. The combination of motion, decision-making, and blood loss metrics offers a multilevel performance assessment, analyzing both technical and decision-making abilities. Copyright © 2017 Elsevier Inc.

    To explore microcirculatory changes within the first 48 hours after admission, to compare them with clinical manifestations of bleeding and to define the dependence of recurrent bleeding from the therapy. The study included 108 patients with ulcerative gastroduodenal bleeding who were treated at the Clinical Hospital #71 for the period 2012-2014. There were 80 (74.1%) men and 28 (25.9%) women. Age ranged 20-87 years (mean 54.4±16.8 years). Patients younger than 45 years were predominant (33.4%). J. Forrest classification (1974) was used in endoscopic characterization of bleeding. Roccal Prognostic Scale for gastroduodenal bleeding was applied in all patients at admission to assess the risk of possible recurrence. Patients were divided into 2 groups. Group 1 included 53 (49.1%) patients without recurrent bleeding; group 2-55 (50.1%) patients who had recurrent bleeding within the first two days of treatment. Investigation of microcirculation showed the role of vegetative component including blood circulation centralization, blood flow slowing, blood cells redistribution providing sufficient blood oxygenation. By the end of the first day we observed pronounced hemodilution, decreased blood oxygenation, blood flow restructuring with its acceleration above 1 ml/s, violation of tissue oxygenation, signs of hypovolemia. These changes were significantly different from group 2 and associated with circulatory decentralization with possible pulmonary microcirculation disturbances and interstitial edema. This processes contribute to disruption of tissue oxygenation. We assume that recurrent bleeding in group 2 was caused by fluid therapy in larger volumes than it was necessary in this clinical situation. Infusion therapy should be significantly reduced for the debut of gastroduodenal ulcerative bleeding. Sedative therapy is advisable to reduce the influence of central nervous system.

    Local excision may be an another option for selected patients with markedly down-staged rectal cancer after preoperative chemoradiation therapy (CRT), and proper evaluation of post-CRT tumor stage (ypT) is essential prior to local excision of these tumors. This study was designed to determine the correlations between endoscopic findings and ypT of rectal cancer. In this study, 481 patients with locally advanced rectal cancer who underwent preoperative CRT followed by surgical resection between 2004 and 2013 at a single institution were evaluated retrospectively. Pathological good response (p-GR) was defined as ypT ≤ 1, and pathological minimal or no response (p-MR) as ypT ≥ 2. The patients were randomly classified according to two groups, a testing (n=193) and a validation (n=288) group. Endoscopic criteria were determined from endoscopic findings and ypT in the testing group and used in classifying patients in the validation group as achieving or not achieving p-GR. Based on findings in the testing group, the endoscopic criteria for p-GR included scarring, telangiectasia, and erythema, whereas criteria for p-MR included nodules, ulcers, strictures, and remnant tumors. In the validation group, the kappa statistic was 0.965 (p < 0.001), and the sensitivity, specificity, positive predictive value, and negative predictive value were 0.362, 0.963, 0.654, and 0.885, respectively. The endoscopic criteria presented are easily applicable for evaluation of ypT after preoperative CRT for rectal cancer. These criteria may be used for selection of patients for local excision of down-staged rectal tumors, because patients with p-MR could be easily ruled out.

    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.

    Acute gastrointestinal bleeding may be localized using noninvasive radionuclide methods. We have favored the use of technetium-99m sulfur colloid with sequential imaging because of the rapid clearance of background activity. Definition of the site of upper gastrointestinal bleeding, however, may be obscured by intense uptake of radioactivity by liver and spleen. The sensitivity of the method is such that the bleeding rates of 0.05-0.1 ml/min can be detected compared to a sensitivity of 0.5 ml/min for angiography.

  13. Diagnosis and Management of Rectal Neuroendocrine Tumors

    Full Text Available The incidence of rectal neuroendocrine tumors (NETs has increased by almost ten-fold over the past 30 years. There has been a heightened awareness of the malignant potential of rectal NETs. Fortunately, many rectal NETs are discovered at earlier stages due to colon cancer screening programs. Endoscopic ultrasound is useful in assessing both residual tumor burden after retrospective diagnosis and tumor characteristics to help guide subsequent management. Current guidelines suggest endoscopic resection of rectal NETs ≤10 mm as a safe therapeutic option given their low risk of metastasis. Although a number of endoscopic interventions exist, the best technique for resection has not been identified. Endoscopic submucosal dissection (ESD has high complete and en-bloc resection rates, but also an increased risk of complications including perforation. In addition, ESD is only performed at tertiary centers by experienced advanced endoscopists. Endoscopic mucosal resection has been shown to have variable complete resection rates, but modifications to the technique such as the addition of band ligation have improved outcomes. Prospective studies are needed to further compare the available endoscopic interventions, and to elucidate the most appropriate course of management of rectal NETs.

    The transforming growth factor-β-signaling pathway has been identified as being involved in colorectal cancer. The aim of this study was to determine how diet and lifestyle factors in combination with genetic variation in the transforming growth factor-β-signaling pathway alters colorectal cancer risk. We used data from 2 population-based case-control studies. Participants included patients with colon cancer (n = 1574) and controls (n = 1970) and patients with rectal cancer ( n = 791) and controls (n = 999). The primary outcomes measured were newly diagnosed cases of colon or rectal cancer. Colon and rectal cancer risk increased with the number of at-risk genotypes within the transforming growth factor-β-signaling pathway (OR 3.68, 95% CI 2.74,4.94 for colon cancer; OR 3.89, 95% CI 2.66,5.69 for rectal cancer). A high at-risk lifestyle score also resulted in significant increased risk with number of at-risk lifestyle factors (OR 2.99, 95% CI 2.32,3.85 for colon cancer; OR 3.37, 95% CI 2.24,5.07 for rectal cancer). The combination of high-risk genotype and high-risk lifestyle results in the greatest increase in risk (OR 7.89, 95% CI 4.45,13.96 for colon cancer; OR 8.75, 95% CI 3.66,20.89 for rectal cancer). The study results need validation in other large studies of colon and rectal cancer. In summary, our data suggest that there is increased colon and rectal cancer risk with increasing number of at-risk genotypes and at-risk lifestyle factors. Although the integrity of the pathway can be diminished by a number of high-risk genotypes, this risk can be offset, in part, by maintaining a healthy lifestyle.

    AIM To analyses the current literature regarding the urogenital functional outcomes of patients receiving robotic rectal cancer surgery. METHODS 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. RESULTS 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 threesexual 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. CONCLUSION 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.

    Close rectal dissection is a surgical technique used by some surgeons in inflammatory bowel disease. It is performed within the mesorectum, close to the rectal muscle wall, with the aim of minimizing damage to the pelvic sexual nerves. Other surgeons dissect in the more anatomical mesorectal plane. Our aim was to determine whether close rectal dissection is more protective of the pelvic sexual nerves than mesorectal dissection. Patients undergoing surgery for inflammatory bowel disease were entered prospectively into a database. Male patients were mailed a standardized, validated, urologic impotence questionnaire: the International Index of Erectile Function. There was an 81 percent response rate. Six of 156 assessable patients were totally impotent (3.8 percent). They were all in the 50-year-old to 70-year-old age group, with no impotence in patients younger than 50 years old. Twenty-one patients complained of minor diminution of erectile function (13.5 percent), where sexual activity was still possible. There was no statistical difference in the rate of complete (2.2 percent vs. 4.5 percent, P = 0.67) or partial (13.5 percent vs. 13.3 percent, P = 0.99) impotence between close rectal and mesorectal dissection (Fisher's exact test). There were no ejaculatory difficulties. The time elapsed since surgery ranged from 2.7 months to 192.7 months, with a median of 74.5 months. Rectal excision for inflammatory bowel disease can be conducted with low rates of impotence. Minor degrees of erectile dysfunction may be more common than currently recognized. We could not demonstrate that close rectal dissection significantly protects the patient from impotence compared with operating in the anatomical mesorectal plane. Age appears to be the most important risk factor for postoperative impotence.

    Peptic ulcer bleeding remains a deadly disease, and a simple indicator of long-term outcomes is crucial. This study validated whether hypoalbuminemia and its related factors in patients with peptic ulcer bleeding can indicate long-term mortality and rebleeding under proton pump inhibitor use. The prospective cohort study enrolled 426 patients with peptic ulcer bleeding who had high risk stigmata at endoscopy and had received endoscopic hemostasis. They were divided into 79 patients in the hypoalbuminemia group (Hypo-AG, serum albumin ulcer size ≥1.0 cm independently (p peptic ulcer bleeding can be an alarm indicator of all-cause mortality and recurrent bleeding in a long-term follow-up situation under proton pump inhibitor use (NCT01591083).

    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.

    The total meso-rectal excision allows the marked increase of the local control rate in rectal cancer. Therefore, the meso-rectal space is the usual field for the spread of rectal cancer cells. It could therefore be considered as the clinical target volume in the preoperative plan by the radiation oncologist. We propose to identify the mesorectum on anatomical structures of a treatment-position CT scan. (authors)

    MR has not yet come into widespread use for the staging of rectal cancer. However use of MR imaging in diagnosis of rectal cancer gains clinical acceptance. Use contrast media enables exact staging of rectal cancer. MR multiplaner and noninvasive imaging with excellent spatial and contrast resolution has rising popularity in diagnosis of rectal cancer, especially in cases where it is impossible to insert endorectal US-probe because of stenosis.

    Full Text Available Introduction: With improving survival of rectal cancer, functional outcome has become in- creasingly important. Following sphincter-preserving resection many patients suffer from severe bowel dysfunction with an impact on quality of life (QoL – referred to as low ante- rior resection syndrome (LARS. Study objective: To provide an overview of the current knowledge of LARS regarding symp- tomatology, occurrence, risk factors, pathophysiology, evaluation instruments and treat- ment options. Results: LARS is characterized by urgency, frequent bowel movements, emptying difficulties and incontinence, and occurs in up to 50-75% of patients on a long-term basis. Known risk factors are low anastomosis, use of radiotherapy, direct nerve injury and straight anasto- mosis. The pathophysiology seems to be multifactorial, with elements of anatomical, sen- sory and motility dysfunction. Use of validated instruments for evaluation of LARS is es- sential. Currently, there is a lack of evidence for treatment of LARS. Yet, transanal irrigation and sacral nerve stimulation are promising. Conclusion: LARS is a common problem following sphincter-preserving resection. All pa- tients should be informed about the risk of LARS before surgery, and routinely be screened for LARS postoperatively. Patients with severe LARS should be offered treatment in order to improve QoL. Future focus should be on the possibilities of non-resectional treatment in order to prevent LARS.

    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.

    The most common reasons for gynecological bleeding are pregnancy-related disorders, fibroids of the uterus, and gynecological malignances. Transarterial embolization is an effective treatment modality for gynecological bleeding regardless of its etiology. Depending on the underlying disease, a different technique of embolization is applied. In postpartal bleeding a temporary effect of embolization is desired, therefore gelatine sponge is used as embolizing agent. In fibroids and malignant tumors the effect should permanent, therefore PVA particles are used. Regardless the etiology, the technical and clinical success of transarterial embolization is at least 90%. In nearly every patient a post-embolization syndrome can be observed, represented by local pain and fever. This post-embolization syndrome usually does not last longer than 3 days. If embolization is performed with meticulous attention to angiographic technique and handling of embolic material, ischemic damage of adjacent organs is rarely observed. Transarterial embolization should be an integrative modality in the treatment of gynecological bleeding. (orig.) [de

    To define the various causes of nonvariceal upper gastrointestinal bleeding, to outline management modalities and to determine the final outcome of patients. A retrospective analysis of patients presenting with upper gastrointestinal (UGI) bleeding from January 2003 to December 2006 (4 years) was conducted. Patients with endoscopically proven variceal bleeding were excluded. Out of the 120 patients, most of the patients belonged to an age group of more than 50 years (mean 48.5 years). Haematemesis was the most common presentation and Acute Gastric Mucosal Lesion (AGML) was the most frequently encountered lesion. The cause of bleeding was not identified in 10 patients (undetermined group). Twenty-two (18.3%) underwent surgery and we had an overall mortality of 15.8%. AGML being the leading cause can be managed conservatively most of the time. There is a male preponderance and the incidence and mortality increases with advancing age. The undetermined group remains a diagnostic problem. (author)

    Full Text Available Abstract Background The relationship between radiation exposure for treatment of cancer and occurrence of a second primary cancer at the irradiated site is well known. This phenomenon is however rare in prostate. Case presentation A 75-year-old farmer was treated for rectal cancer with preoperative 45 Gy of radiotherapy and abdominoperineal resection. Four years later he developed symptoms of bladder outlet obstruction and acute urinary retention. He underwent a transurethral resection of the prostate. Histological examination of the removed prostate tissue and immunohistochemistry revealed it to be a poorly differentiated sarcoma. Conclusion We believe this to be the first reported case of radiation-induced sarcoma following radiotherapy treatment for rectal cancer. Since radiotherapy plays a pivotal role in the contemporary treatment of rectal adenocarcinoma, it is relevant to be aware of the potential long-term carcinogenic complications of radiotherapy of the pelvis.

    Until quite recently, rectal prolapse was regarded as being a simple condition to treat. Surgical control of the prolapse was largely regarded as a successful outcome. However, recent detailed clinical assessment indicate that many patients have a rectal prolapse which is successfully controlled by surgical operation, yet suffer severe symptoms of disordered defecation, which either persists, or develops as a result of operative treatment. Difficulty with rectal evacuation, persistent incontinence and continuing mucus discharge are recognized as important, despite successful repair of the prolapse itself. There are two major theory of the pathology; circumferential intussusception and sliding hernia. However, many other multifarious factors are concomitant with the condition. These factors often need to be balanced against one another. Usually, a single surgical procedure will not be able to solve the problems. Therefore, the choice of treatment tailored for the individual patient. (author)

    Almost 50% of women who have had rectal surgery subsequently develop vaginal discharge. Due to the recurrent and unexpected nature of this heavy discharge, they often experience it as very distressing. Many of these women undergo extensive diagnostic tests that are mainly focused on identifying fistula formation. If no fistula is found, in most cases no other cause for severe vaginal discharge can be demonstrated. In our practice, we saw three patients (49-, 54- and 74-years-old, respectively) with similar severe vaginal discharge after rectal surgery and in whom no explanation for the vaginal discharge could be found. For this reason we conducted a literature search into this condition. Anatomical changes appear to be responsible for heavy vaginal discharge following rectal surgery. Changes in pelvic floor muscles and compression of the distal part of the vagina may lead to pooling of fluid in the proximal part of the vagina, resulting in severe discharge. Symptomatic treatment may reduce the symptoms.

    To determine the pathologic effectiveness of preoperative chemoradiotherapy (CRT) in patients with advanced rectal carcinoma, we reviewed clinical records of 76 patients who received preoperative pelvic radiation +/- chemotherapy. Since 2 patients refused operation and 2 died before surgery, 72 patients underwent operation with a mean delay of 19.9 days after completion of irradiation. Pathologic tumor regression grade (Grade 0-3) was determined by the amount of viable tumor versus necrosis and fibrosis. Grade 0, 1a, 1b, 2, and 3 (pCR) were observed in 0%, 25.0%, 38.9%, 27.8% and 2.8% of patients, respectively. The pathologic response (PR) rate was 75.0% when PR was defined as greater than grade 1b (tumor regression more than 1/3). Downstaging was observed in 35.8% of patients, in which 5-year overall survival was significantly better than in patients without downstaging (90.0% vs. 50.1%, p<0.05). No correlation could be observed between PR and downstaging. CRT is a useful tool with a high PR rate in patients with advanced rectal cancer. More accurate and careful clinical staging is important to select adequate candidates for CRT. Multi-institutional clinical trials as well as standardizing the surgical procedure including lymph node (LN) dissection are required to validate the advantages of CRT for Japanese patients.

    effects on five-year disease-free survival (OR 1.02; 95% CI 0.76 to1.38, 4 studies, N = 943). The estimated effects of laparoscopic and open TME on local recurrence and overall survival were similar, although confidence intervals were wide, both with moderate quality evidence (local recurrence: OR 0.89; 95% CI 0.57 to1.39 and overall survival rate: OR 1.15; 95% CI 0.87 to1.52). There was moderate to high quality evidence that the number of resected lymph nodes and surgical margins were similar between the two groups.For the short-term results, length of hospital stay was reduced by two days (95% CI -3.22 to -1.10), moderate quality evidence), and the time to first defecation was shorter in the LTME group (-0.86 days; 95% CI -1.17 to -0.54). There was moderate quality evidence that 30 days morbidity were similar in both groups (OR 0.94; 95% CI 0.8 to 1.1). There were fewer wound infections (OR 0.68; 95% CI 0.50 to 0.93) and fewer bleeding complications (OR 0.30; 95% CI 0.10 to 0.93) in the LTME group.There was no clear evidence of any differences in quality of life after LTME or OTME regarding functional recovery, bladder and sexual function. The costs were higher for LTME with differences up to GBP 2000 for direct costs only. We have found moderate quality evidence that laparoscopic total mesorectal excision (TME) has similar effects to open TME on long term survival outcomes for the treatment of rectal cancer. The quality of the evidence was downgraded due to imprecision and further research could impact on our confidence in this result. There is moderate quality evidence that it leads to better short-term post-surgical outcomes in terms of recovery for non-locally advanced rectal cancer. Currently results are consistent in showing a similar disease-free survival and overall survival, and for recurrences after at least three years and up to 10 years, although due to imprecision we cannot rule out superiority of either approach. We await long-term data from a number of

    To assess the effect of a shrinking rectal balloon implant (RBI) on the anorectal dose and complication risk during the course of moderately hypofractionated prostate radiotherapy. In 15 patients with localized prostate cancer, an RBI was implanted. A weekly kilovolt cone-beam computed tomography (CBCT) scan was acquired to measure the dynamics of RBI volume and prostate-rectum separation. The absolute anorectal volume encompassed by the 2 Gy equieffective 75 Gy isodose (V{sub 75Gy}) was recalculated as well as the mean anorectal dose. The increase in estimated risk of grade 2-3 late rectal bleeding (LRB) between the start and end of treatment was predicted using nomograms. The observed acute and late toxicities were evaluated. A significant shrinkage of RBI volumes was observed, with an average volume of 70.4% of baseline at the end of the treatment. Although the prostate-rectum separation significantly decreased over time, it remained at least 1 cm. No significant increase in V{sub 75Gy} of the anorectum was observed, except in one patient whose RBI had completely deflated in the third week of treatment. No correlation between mean anorectal dose and balloon deflation was found. The increase in predicted LRB risk was not significant, except in the one patient whose RBI completely deflated. The observed toxicities confirmed these findings. Despite significant decrease in RBI volume the high-dose rectal volume and the predicted LRB risk were unaffected due to a persistent spacing between the prostate and the anterior rectal wall.

    2012-03-01

    This guideline presents recommendations for the step-wise management of patients with overt upper gastrointestinal bleeding. Hemodynamic status is first assessed, and resuscitation initiated as needed. Patients are risk-stratified based on features such as hemodynamic status, comorbidities, age, and laboratory tests. Pre-endoscopic erythromycin is considered to increase diagnostic yield at first endoscopy. Pre-endoscopic proton pump inhibitor (PPI) may be considered to decrease the need for endoscopic therapy but does not improve clinical outcomes. Upper endoscopy is generally performed within 24h. The endoscopic features of ulcers direct further management. Patients with active bleeding or non-bleeding visible vessels receive endoscopic therapy (e.g., bipolar electrocoagulation, heater probe, sclerosant, clips) and those with an adherent clot may receive endoscopic therapy; these patients then receive intravenous PPI with a bolus followed by continuous infusion. Patients with flat spots or clean-based ulcers do not require endoscopic therapy or intensive PPI therapy. Recurrent bleeding after endoscopic therapy is treated with a second endoscopic treatment; if bleeding persists or recurs, treatment with surgery or interventional radiology is undertaken. Prevention of recurrent bleeding is based on the etiology of the bleeding ulcer. H. pylori is eradicated and after cure is documented anti-ulcer therapy is generally not given. Nonsteroidal anti-inflammatory drugs (NSAIDs) are stopped; if they must be resumed low-dose COX-2-selective NSAID plus PPI is used. Patients with established cardiovascular disease who require aspirin should start PPI and generally re-institute aspirin soon after bleeding ceases (within 7 days and ideally 1-3 days). Patients with idiopathic ulcers receive long-term anti-ulcer therapy.

    Purpose: Clinical symptomatic late injury to the rectal wall occurs in about one-third of patients with prostate cancer treated with external beam irradiation. Reducing the physical dose to the anterior rectal wall without a similar reduction in the posterior peripheral zone is difficult because of the proximity of the prostate to the anterior rectal wall. On the basis of our previous observations in an animal model that intrarectal application of amifostine resulted in very high concentrations of amifostine and its active metabolite WR-1065 in the rectal wall, a Phase I dose-escalation clinical trial was undertaken. Methods and Materials: Twenty-nine patients with localized prostate cancer were accrued. Eligibility criteria included histologically confirmed adenocarcinoma, Karnofsky performance status ≥70, and no pelvic lymphadenopathy or distant metastases. The total dose to the prostate was 70.2 Gy in 20 patients and 73.8 Gy in 9 patients. Therapy was delivered using a 4-field technique with three-dimensional conformal planning. Amifostine was administered intrarectally as an aqueous solution 30 min before irradiation on the first 15 days of therapy. Amifostine was escalated in cohorts from 500 to 2500 mg. Proctoscopy was performed before therapy and at 9 months after completion. Most patients underwent repeat proctoscopy at 18 months. On Days 1 and 10 of radiotherapy, serum samples were collected for pharmacokinetic studies. The clinical symptoms (Radiation Therapy Oncology Group scale) and a proctoscopy score were assessed during follow-up. Results: All patients completed therapy with no amifostine-related toxicity at any dose level. The application was feasible and well tolerated. No substantial systemic absorption occurred. With a median follow-up of 26 months, 9 patients (33%) developed rectal bleeding (8 Grade 1, 1 Grade 2). At 9 months, 16 and 3 patients developed Grade 1 and Grade 2 telangiectasia, respectively. This was mostly confined to the anterior

    Assessment of satisfaction with life, as a result of comparing own life situation with the individualised personal standards, is an important element for measuring satisfaction with life of the patients suffering from somatic disorders. Literature provides numerous data on satisfaction with life of different groups of patients suffering from somatic disorders. Little space is devoted to the study of the level of satisfaction of patients with rectal prolapse, which is particularly evident in relation to the Polish patient population. The aim of the study was planned to determine the level of satisfaction with life and its determinants among patients with full-thickness rectal prolapse surgery as well as to assess the improvement of continence after this surgery. The study group consisted of 20 patients operated on for full-thickness rectal prolapse in the Department of General and Colorectal Surgery, Medical University in Lódź. SWLS (Satisfaction with Life Scale) Diener et al. in the Polish adaptation by Juczyński was used to assess global life satisfaction. Assessment of the incontinence severity and the postoperative improvement was made with Jorge and Wexner scale. The average level of global life satisfaction among patients with rectal prolapse surgery is 21.05 (SD = 4.68) and it corresponds to the level of satisfaction of the total population. In the study group, there were no statistically significant differences in the level of global satisfaction with life depending on age, disease recurrence and continence improvement after surgery. The continence after rectal prolapse surgery improved significantly (plife satisfaction of patients operated on for rectal prolapse.

    Aim: To determine whether patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy with increased sampling numbers are more likely to experience bleeding complications and whether warfarin or low-dose aspirin are independent risk factors. Materials and methods: 930 consecutive patients with suspected prostatic cancer were followed up after biopsy. Warfarin/low-dose aspirin was not stopped prior to the procedure. An eight to 10 sample regime TRUS-guided prostate biopsy was performed and patients were offered a questionnaire to complete 10 days after the procedure, to determine any immediate or delayed bleeding complications. Results: 902 patients returned completed questionnaires. 579 (64.2%) underwent eight core biopsies, 47 (5.2%) underwent nine, and 276 (30.6%) underwent 10. 68 were taking warfarin [mean international normalized ratio (INR) = 2.5], 216 were taking low-dose aspirin, one was taking both, and 617 were taking neither. 27.9% of those on warfarin and 33.8% of those on aspirin experienced haematuria. 37% of those on no blood-thinning medication experienced haematuria. 13.2% of those on warfarin and 14.4% of those on aspirin experienced rectal bleeding. 11.5% of those on no blood-thinning medication experienced rectal bleeding. 7.4% of those on warfarin and 12% of those on aspirin experienced haematospermia. 13.8% of those on neither experienced haematospermia. Regression analysis showed a significant association between increasing sampling number and occurrence of all bleeding complication types. There was no significant association between minor bleeding complications and warfarin use; however, there was a significant association between minor bleeding complications and low-dose aspirin use. There was no severe bleeding complication. Conclusion: There is an increased risk of bleeding complications following TRUS-guided prostate biopsy with increased sampling numbers but these are minor. There is also an increased risk with low

    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.

    Angiography is essential for the detection of bleeding vessels in traumatic vascular injury. Immediately after the diagnosis, transcatheter embolization can be performed for the control of bleeding effectively and easily with proper use of embolic materials. Transcatheter embolization is believed to be the treatment of choice when emergency control is needed, where surgical approach is difficult and in those who are poor candidate for surgery. We have tried bleeding control in 18 cases of trauma over recent 4 years. The results were as follows; 1. Causes of bleeding(cases): Blunt or penetrating trauma (10), latrogenic trauma (8), (Postoperative (5), Needle biopsy (2), Percutaneous hepatic procedure (1)) 2. Embolized vessels: Renal artery branches (8), Hepatic artery branches (2), Arteries supplying chest wall (2), External carotid artery branches (3), Internal carotid artery (1), Circumflex humeral artery (1), Internal iliac artery branches (1). 3. Embolic agents: Gelfoam cubes (16), Stainless steel coils (3), Detachable latex balloon (1). 4. Successful bleeding control was achieved in 17 cases and reduction of the amount of bleeding in one case without significant complications

    To evaluate the effectiveness of the hysteroscopic polypectomy in terms of the decrease of the abnormal uterine bleeding. A cross-sectional and analytical study was done with patients to whom a hysteroscopic polypectomy was done for treating the abnormal uterine bleeding, between January 2009 and December 2013. The response to the treatment was evaluated via a survey given to the patients about the behavior of the abnormal uterine bleeding after the procedure and about overall satisfaction. The results were obtained after a hysteroscopic polypectomy done to 128 patients and were as follows. The average time from the polypectomy applied until the survey was 30.5 months, with a standard deviation of 18 months. 67.2% of the patients reported decreased abnormal uterine bleeding and the 32.8% reported a persistence of symptoms. On average 82.8% of the. patients were satisfied with the treatment. Bivariate and multivariate analysis showed no association between the variables studied and no improvement of abnormal uterine bleeding after surgery (polypectomy). There were no complications. Hysteroscopic polypectomy is a safe surgical treatment, which decreases on two of three patients the abnormal uterine bleeding in the presence of endometrial polyps, with an acceptable level of satisfaction.

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

    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.

    The human rectum represents a body cavity in which drugs can be easily introduced and retained and from which absorption is well possible. There are important therapeutic reasons why it is sometimes preferable to give a drug rectally rather than orally, e.g. in cases of nausea and vomiting. Drawbacks of rectal drug administration include the interruption of absorption by defaecation and lack of patient acceptability. The mechanism of drug absorption from the rectum is probably no different to that in the upper part of the gastrointestinal tract, despite the fact that the physiological circumstances (e.g. pH, fluid content) differ substantially, Absorption from aqueous and alcoholic solutions may occur very rapidly, which has proved to be of considerable therapeutic value in the rapid suppression of acute convulsive attacks by diazepam (e.g. in children), but absorption from suppositories is generally slower and very much dependent on the nature of the suppository base, the use of surfactants or other additives, particle size of the active ingredient, etc. There is some evidence that hepatic first-pass elimination of high clearance drugs is partially avoided after rectal administration, e.g. lignocaine. This can be explained by the rectal venous blood supply: the upper part is connected with the portal system, whereas the lower part is directly connected with the systemic circulation. Plasma concentration data following rectal administration of representatives of several classes of drugs are reviewed: anticonvulsants, non-narcotic analgesics and non-steroidal anti-inflammatory agents, hypnosedatives and anaesthetics, strong analgesics, theophylline and derivatives, corticosteroids, antibacterial agents, thiazinamium, promethazine, hyoscine-N-butyl-bromide, streptokinase, progesterone, ergotamine tartrate and levodopa. Only limited number of cases has it been adequately shown that the rectal route of administration gives plasma concentrations which are comparable to

    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.

    Bleeding assessment tools have evolved in the last decade to standardize the assessment of the severity of bleeding symptom in a consistent way. In 2010, the International Society on Thrombosis and Hemostasis-Bleeding Assessment Tool (ISTH-BAT) was developed and validated. Our aim was to administer ISTH-BAT questionnaire to the Omani patients with type 1 VWD and obtain the bleeding score (BS). We also studied the severity of their bleeding symptoms and correlated it with the BS as well as with the laboratory parameters. Forty-eight type I VWD index cases and 52 normal subjects were interviewed and the ISTH-BAT questionnaire administered. The BS was calculated based on a history of bleeding symptoms from 12 different sites according to the standard ISTH-BAT questionnaire. Laboratory parameters were obtained from patient's medical records. The mean age of this cohort was 27 years (range, 6-49) with 60% being females. The median time to administer this questionnaire was 10 minutes with an interquartile range (IQR) from 8 to 17 minutes. Overall, the median BS was 7 (IQR; 2,11) although individual scores ranged between 0 and 36. The BS was negatively correlated with VWF: Ag, VWF: RCo, and VWF: CB and the Spearman's correlation coefficient "rho" was, respectively, -0.15, -0.08, and -0.22. The ISTH-BAT BS is designed to reflect the severity of bleeding. Our results demonstrate the inherent variability of this bleeding pattern. We also found that the ISTH-BAT BS significantly correlated with VWF: Ag and VWF: CB. © 2017 John Wiley & Sons Ltd.

    To assess the bleeding risk profile using the HAS-BLED score in patients with symptomatic peripheral artery disease (PAD). A post hoc analysis was performed using data from a series of 115 consecutive patients (mean age 72.4±11.4 years; 68 men) with symptomatic PAD undergoing endovascular revascularization. The endpoint of the study was to assess bleeding risk using the 9-point HAS-BLED score, which was previously validated in cohorts of patients with and without atrial fibrillation. For the purpose of this study, the low (0-1), intermediate (2), and high-risk (≥3) scores were stratified as low/intermediate risk (HAS-BLED risk (HAS-BLED ≥3). The mean HAS-BLED score was 2.76±1.16; 64 (56%) patients had a HAS-BLED score ≥3.0. Patients with PAD Rutherford category 5/6 ischemia had an even higher mean HAS-BLED score (3.20±1.12). Logistic regression analysis revealed aortoiliac or femoropopliteal segment involvement, chronic kidney disease, as well as Rutherford category 5/6, to be independent risk factors associated with a HAS-BLED score ≥3. Patients with PAD, especially those presenting with Rutherford category 5/6 ischemic symptoms, have high HAS-BLED scores, suggesting increased risk for major bleeding. Prospective clinical validation of the HAS-BLED score in patients with PAD may help with the risk-benefit assessment when prescribing antithrombotic therapy. © The Author(s) 2016.

    Gastrointestinal bleeding (GIB) is a common and often serious complication after stroke. Although several risk factors for post-stroke GIB have been identified, no reliable or validated scoring system is currently available to predict GIB after acute stroke in routine clinical practice or clinical trials. In the present study, we aimed to develop and validate a risk model (acute ischemic stroke associated gastrointestinal bleeding score, the AIS-GIB score) to predict in-hospital GIB after acute ischemic stroke. The AIS-GIB score was developed from data in the China National Stroke Registry (CNSR). Eligible patients in the CNSR were randomly divided into derivation (60%) and internal validation (40%) cohorts. External validation was performed using data from the prospective Chinese Intracranial Atherosclerosis Study (CICAS). Independent predictors of in-hospital GIB were obtained using multivariable logistic regression in the derivation cohort, and β-coefficients were used to generate point scoring system for the AIS-GIB. The area under the receiver operating characteristic curve (AUROC) and the Hosmer-Lemeshow goodness-of-fit test were used to assess model discrimination and calibration, respectively. A total of 8,820, 5,882, and 2,938 patients were enrolled in the derivation, internal validation and external validation cohorts. The overall in-hospital GIB after AIS was 2.6%, 2.3%, and 1.5% in the derivation, internal, and external validation cohort, respectively. An 18-point AIS-GIB score was developed from the set of independent predictors of GIB including age, gender, history of hypertension, hepatic cirrhosis, peptic ulcer or previous GIB, pre-stroke dependence, admission National Institutes of Health stroke scale score, Glasgow Coma Scale score and stroke subtype (Oxfordshire). The AIS-GIB score showed good discrimination in the derivation (0.79; 95% CI, 0.764-0.825), internal (0.78; 95% CI, 0.74-0.82) and external (0.76; 95% CI, 0.71-0.82) validation cohorts

    Heavy menstrual bleeding (HMB) is an important physical and social problem for women. Oral treatment for HMB includes antifibrinolytic drugs, which are designed to reduce bleeding by inhibiting clot-dissolving enzymes in the endometrium.Historically, there has been some concern that using the antifibrinolytic tranexamic acid (TXA) for HMB may increase the risk of venous thromboembolic disease. This is an umbrella term for deep venous thrombosis (blood clots in the blood vessels in the legs) and pulmonary emboli (blood clots in the blood vessels in the lungs). To determine the effectiveness and safety of antifibrinolytic medications as a treatment for heavy menstrual bleeding. We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO and two trials registers in November 2017, together with reference checking and contact with study authors and experts in the field. We included randomized controlled trials (RCTs) comparing antifibrinolytic agents versus placebo, no treatment or other medical treatment in women of reproductive age with HMB. Twelve studies utilised TXA and one utilised a prodrug of TXA (Kabi). We used standard methodological procedures expected by Cochrane. The primary review outcomes were menstrual blood loss (MBL), improvement in HMB, and thromboembolic events. We included 13 RCTs (1312 participants analysed). The evidence was very low to moderate quality: the main limitations were risk of bias (associated with lack of blinding, and poor reporting of study methods), imprecision and inconsistency.Antifibrinolytics (TXA or Kabi) versus no treatment or placeboWhen compared with a placebo, antifibrinolytics were associated with reduced mean blood loss (MD -53.20 mL per cycle, 95% CI -62.70 to -43.70; I² = 8%; 4 RCTs, participants = 565; moderate-quality evidence) and higher rates of improvement (RR 3.34, 95% CI 1.84 to 6.09; 3 RCTS, participants = 271; moderate-quality evidence). This suggests that

    Acute gastrointestinal bleeding-massive acute bleeding from gastrointestinal section is one of the most frequent forms of acute abdomen. The mortality degree in emergency surgery is about 10%. It's very difficult to identify the place of bleeding and etiology. The important purpose of this research is to present the cases of acute gastrointestinal bleeding from the patients which were monitored and treated at The University Clinical Center of Kosova-Emergency Center in Pristina. These inquests included 137 patients with acute gastrointestinal bleeding who were treated in emergency center of The University Clinical Center in Pristina for the period from January 2005 until December 2006. From 137 patients with acute gastrointestinal bleeding 41% or 29% was female and 96% or 70.1% male. Following the sex we gained a high significant difference of statistics (p < 0.01). The gastrointestinal bleeding was two times more frequent in male than in female. Also in the age-group we had a high significant difference of statistics (p < 0.01) 63.5% of patients were over 55 years old. The mean age of patients with an acute gastrointestinal bleeding was 58.4 years SD 15.8 age. The mean age for female patients was 56.4 age SD 18.5 age. The patients with arterial systolic pressure under 100 mmHg have been classified as patients with hypovolemic shock. They participate with 17.5% in all prevalence of acute gastrointestinal bleeding. From the number of prevalence 2 {1.5%} patients have been diagnosed with peptic ulcer, 1 {0.7%} as gastric perforation and 1 {0.7%} with intestine ischemia. Abdominal Surgery and Intensive Care 2 or 1.5% died, 1 at intensive care unit and 1 at nephrology. As we know the severe condition of the patients with gastrointestinal bleeding and etiology it is very difficult to establish, we need to improve for the better conditions in our emergency center for treatment and initiation base of clinic criteria.

    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.

    Congenital rectal duplication cyst is a rare entity treated with surgical excision. Without treatment, a rectal duplication cyst may cause a variety of complications, most notably, transforming into a malignancy. We report on a 7-week-old girl who was found to have a rectal duplication cyst. The rectal duplication cyst was successfully excised laparoscopically. Rectal duplication cysts are rare alimentary tract anomalies generally discovered during childhood. Complications include symptoms arising from the cyst and the possibility of malignant degeneration. They are typically managed by surgical excision.

    Background: Aberrant DNA methylation is more prominent in proximal compared with distal colorectal cancers. Although a number of methylation markers were identified for colon cancer, yet few are available for rectal cancer. Methods: DNA methylation differences were assessed by a targeted DNA microarray for 360 marker candidates between 22 fresh frozen rectal tumour samples and 8 controls and validated by microfluidic high-throughput and methylation-sensitive qPCR in fresh frozen and formalin-fixed paraffin-embedded (FFPE) samples, respectively. The CpG island methylator phenotype (CIMP) was assessed by MethyLight in FFPE material from 78 patients with pT2 and pT3 rectal adenocarcinoma. Results: We identified and confirmed two novel three-gene signatures in fresh frozen samples that can distinguish tumours from adjacent tissue as well as from blood with a high sensitivity and specificity of up to 1 and an AUC of 1. In addition, methylation of individual CIMP markers was associated with specific clinical parameters such as tumour stage, therapy or patients' age. Methylation of CDKN2A was a negative prognostic factor for overall survival of patients. Conclusions: The newly defined methylation markers will be suitable for early disease detection and monitoring of rectal cancer. PMID:26335606

    To evaluate the effects of rectal enemas on rectal doses during postoperative high-dose-rate (HDR) vaginal cuff brachytherapy (VCB). This prospective trial included 59 patients. Two rectal cleansing enemas were self-administered before the second fraction, and fraction 1 was considered the basal status. Dose-volume histogram (DVH) values were generated for the rectum and correlated with rectal volume variation. Statistical analyses used paired and unpaired t-tests. Despite a significant 15 % reduction in mean rectal volume (44.07 vs. 52.15 cc, p = 0.0018), 35.6 % of patients had larger rectums after rectal enemas. No significant rectal enema-related DVH differences were observed compared to the basal data. Although not statistically significant, rectal cleansing-associated increases in mean rectal DVH values were observed: D 0.1 cc : 6.6 vs. 7.21 Gy; D 1 cc : 5.35 vs. 5.52 Gy; D 2 cc : 4.67 vs. 4.72 Gy, before and after rectal cleaning, respectively (where D x cc is the dose to the most exposed x cm 3 ). No differences were observed in DVH parameters according to rectal volume increase or decrease after the enema. Patients whose rectal volume increased also had significantly larger DVH parameters, except for D 5 % , D 25 % , and D 50 % . In contrast, in patients whose rectal volume decreased, significance was only seen for D 25 % and D 50 % (D x % dose covering x % of the volume). In the latter patients, nonsignificant reductions in D 2 cc , D 5 cc and V 5 Gy (volume receiving at least 5 Gy) were observed. The current rectal enemas protocol was ineffective in significantly modifying rectal DVH parameters for HDR-VCB. (orig.) [de

    To evaluate rectal hydrocortisone as an emergency glucocorticoid replacement therapy in adrenal insufficient children. A parental questionnaire evaluated preferred treatment, problems or benefits of i.m. and rectal hydrocortisone, frequency and indications for administration and who administered treatment. Admissions of children with adrenal insufficiency were monitored. There were 39/52 families who responded to the questionnaire. 93% (26/28) preferred rectal hydrocortisone. Parents or children who previously received emergency treatment from a doctor now self-administered rectal hydrocortisone. The cost of suppositories and i.m. hydrocortisone is similar; however, storage of suppositories was inconvenient. One girl presented with pneumonia and collapse despite rectal hydrocortisone and a hydrocortisone level at admission of >2000 nmol/l with normal electrolytes. Rectal hydrocortisone is an acceptable and safe emergency therapy. We still advise i.m. hydrocortisone if rectal administration is not possible or with suppository extrusion.

  15. MRI in staging of rectal carcinoma

    2012-01-01

    Full text: MRI of the rectum is performed for initial local staging of primary rectal cancer in order to identify locally advanced rectal cancers and for assessment of treatment response after completion of neoadjuvant therapy. Introduction of new generation MRI scanners with optimal phased array body coils, resulting in improved contrast and spatial resolution images due to better signal to noise ratio, have contributed to production of high resolution images in which visualization of anatomical details such as the mesorectal fascia and the bowel wall layers are feasible. Pre-operative MRI of the rectum using mainly high resolution T2 weighted sequences has gained significant accreditation, especially after the introduction of total mesorectal excision (TME) surgery and neoadjuvant therapy in the treatment regimen of rectal cancer. MR Imaging is so far the only method that can preoperatively identify patients most likely to benefit from neoadjuvant therapy as well as demonstrate high risk patients for local recurrence. Regarding N stage besides of mesorectal lymph nodes which are removed during TME, especially in case of low lying rectal cancers, MRI may provide information regarding external/internal iliac lymph node involvement. High resolution MRI images may demonstrate lymph nodes with a diameter down to 2 mm, however these are still characterized based on their morphological features. Patients identified at initial MRI staging as having locally advanced rectal cancer undergo neoadjuvant chemoradiation therapy (CRT) in order for their tumor to be downsized and downstaged, especially in low rectal cancers so that sphincter sparing surgery may be performed. In 15-30% of patients complete pathological response is achieved. Reimaging with MRI at 6 weeks post treatment is of great importance for assessing tumor response. Conventional MRI has a reported moderate accuracy for prediction of mesorectal fascia (MF) involvement after CRT therapy, mainly due to its

    Objectives: Variceal hemorrhage is a potentially life-threatening complication in cirrhotic patients. Identification of patients at high risk for bleeding is particularly important. The aim of this study was to determine the clinical usefulness of per-rectal portal scintigraphy in evaluation the severity of portal hypertension in cirrhotic patients in terms of correlation between cirrhosis and classic indicators of hepatic functional reserve and identifying the difference of the portal shunt index (PSI) of the bleeding esophageal varices group and non-bleeding esophageal varices group. Material and methods: Portal circulations in 15 healthy volunteer's and in 67 patients with cirrhosis were evaluated by Tc-99m pertechnetate per-rectal p. ortal scintigraphy. Tc-99m pertechnetate (550 MBq) was instilled into the upper rectum, and dynamic images were taken. Radioactivity curves of the liver and the heart were generated sequentially. Through the analysis of these curves, the PSI was determined by calculating the ratio of counts of the liver to counts of the heart integrated for 24 seconds immediately after the appearance of the liver time-activity curve. Results: The results, expressed as PSI were: 13.63 +/- 6.28 % in healthy subjects and 66.32+/-22.80 % in cirrhotic patients. Of these, the PSIs were 56036 +/- 27.14 % in 31 cirrhotic patients without esophageal varices, and 74.89 +/- 13.62 % in 36 cirrhotic patients with esophageal varices. The PSI was significantly lower in cirrhotic patients without bleeding esophageal vances (BEV) than those with BEV (p=0.001). The PSI calculated with this method was correlated with the serum albumin, the serum bilirubin and the Child-Pugh's score. Conclusion: The Tc-99m pertechnetate per-rectal portal scintigraphy has clinical usefulness as a relatively non-invasive method of choice for quantitative evaluating the severity of portal hypertension in cirrhotic patients.

    Full Text Available Background and purpose: Contact brachytherapy is used for the treatment of early rectal cancer. An overview of the current status of quality assurance of the rectal contact brachytherapy systems in the UK, based on a national audit, was undertaken in order to assist users in optimising their own practices. Material and methods: Four UK centres using the Papillon 50 contact brachytherapy system were audited. Measurements included beam quality, output and radiation field size and uniformity. Test frequencies and tolerances were reviewed and compared to both existing recommendations and published reviews on other kV and electronic brachytherapy systems. External validation of dosimetric measurements was provided by the National Physical Laboratory. Results: The maximum host/audit discrepancy in beam quality determination was 6.5%; this resulted in absorbed dose variations of 0.2%. The host/audit agreement in absorbed dose determination was within 2.2%. The median of the radiation field uniformity measurements was 2.7% and the host/audit agreement in field size was within 1 mm. Test tolerances and frequencies were within the national recommendations for kV units. Conclusions: The dosimetric characterisation of the Papillon 50 was validated by the audit measurements for all participating centres, thus providing reassurance that the implementation had been performed within the standards stated in previously published audit work and recommendations for kV and electronic brachytherapy units. However, optimised and standardised quality assurance testing could be achieved by reducing some methodological differences observed. Keywords: Contact brachytherapy, Electronic brachytherapy, Audit

    Multiple procedures and devices are used in a complex interplay to diagnose and treat GI bleeding. To model how a large variety of diagnostic and therapeutic components interact in the successful management of GI bleeding. The analysis uses the concept of reliability block diagrams from probability theory to model management outcome. Separate components of the management process are arranged in a serial or parallel fashion. If the outcome depends on the function of each component individually, such components are modeled to be arranged in series. If components complement each other and can mutually compensate for each of their failures, such components are arranged in a parallel fashion. General endoscopy practice. Patients with GI bleeding of unknown etiology. All available endoscopic and radiographic means to diagnose and treat GI bleeding. Process reliability in achieving hemostasis. Serial arrangements tend to reduce process reliability, whereas parallel arrangements increase it. Whenever possible, serial components should be bridged and complemented by additional alternative (parallel) routes of operation. Parallel components with low individual reliability can still contribute to overall process reliability as long as they function independently of other pre-existing alternatives. Probability of success associated with individual components is partly unknown. Modeling management of GI bleeding by a reliability block diagram provides a useful tool in assessing the impact of individual endoscopic techniques and administrative structures on the overall outcome.

    2018-01-01

    : 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.

  1. Modelling the variation in rectal dose due to inter-fraction rectal wall deformation in external beam prostate treatments

    International Nuclear Information System (INIS)

    Booth, Jeremy; Zavgorodni, Sergei

    2005-01-01

    Prostate radiotherapy inevitably deposits radiation dose in the rectal wall, and the dose delivered to prostate is limited by the expected rectal complications. Accurate evaluation of the rectal dose is non-trivial due to a number of factors. One of these is variation of the shape and position of the rectal wall (with respect to the clinical target volume (CTV)), which may differ daily from that taken during planning CT acquisition. This study uses data currently available in the literature on rectal wall motion to provide estimates of mean population rectal wall dose. The rectal wall geometry is characterized by a population mean radius of the rectum as well as inter-patient and inter-fraction standard deviations in rectum radius. The model is used to evaluate the range of inter-fraction and inter-patient rectal dose variations. The simulation of individual patients with full and empty rectum in the planning CT scan showed that large variations in rectal dose (>15 Gy) are possible. Mean calculated dose accounting for treatment and planning uncertainties in the rectal wall surface was calculated as well as the map of planning dose over/underpredictions. It was found that accuracy of planning dose is dependent on the CTV-PTV margin size with larger margins producing more accurate estimates. Over a patient population, the variation in rectal dose is reduced by increasing the number of pre-treatment CT scans

    To assess the diagnostic accuracy of Roc kall scoring system for predicting in-hospital re-ble- eding in cirrhotic patients presenting with variceal bleed. Material and Methods: This descriptive case series study was conducted at Department of Medicine Combined Military Hospital Lahore from December 2013 to May 2014. We included patients with liver cirrhosis who presented with upper GI bleeding and showed varices as the cause of bleeding on endoscopy. Clinical and endoscopic features were noted to calculate Rockall score. Patients with score < 2 and > 8 were included. After treating with appropriate pharmacological and endoscopic therapy, patients were followed for re-bleeding for 10 days. Diagnostic accuracy was assessed by calculating sensitivity, specificity, positive and negative predictive values using 2 x 2 tables. Results: In the study, 175 patients were included. Mean age was 51.5 ± 1.22 years. Male to female ratio was 1.5 to 1.0 out of 175 patients, 157 patients (89.7%) were of low risk group (score = 2) while 18 patients (10.3%) were in high risk group (score > 8). In low risk group, re-bleeding occurred only in 2 patients (1.2%) while in high risk group, re-bleeding occurred in 14 patients (78%). Rockall score was found to have good diagnostic accuracy with sensitivity of 87.5%, specificity of 97.48%, positive predictive value of 77.8% and negative predictive value of 98.7%. Conclusion: In cases of variceal bleed, frequency of re-bleed is less in patients who are in low risk category with lower Rockall score and high in high risk patients with higher rockall score. The Rockall score has a good diagnostic accuracy in prediction of re-bleed in variceal bleeding. (author)

    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.

    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...

    Full Text Available We report a case of a 50-year-old man with a history of liver cirrhosis and colon cancer post end colostomy presenting to the emergency department with stomal bleeding and passage of clots into the colostomy bag. The patient was treated with transjugular intrahepatic portosystemic shunt (TIPS and concomitant embolization of the stomal varices via the TIPS shunt using N-butyl cyanoacrylate mixed with ethiodol. Although stomal variceal bleeding is uncommon, this entity can have up to 40% mortality upon initial presentation, given the challenges in diagnosis and management. Currently, there are no established standard treatments for stomal variceal bleeding. In addition, to the best of our knowledge, there are no cases in the current literature in which treatment of this entity is performed with a combination of TIPS shunt placement and N-butyl cyanoacrylate variceal embolization.

    Hematuria from a neobladder can occur due to a variety of pathologies including tumors, stones, and fistulas. Variceal bleeding in a neobladder is a very rare condition with only one case reported in literature. We present a case of a patient with cirrhosis and portal hypertension and an ileocolic orthotopic neobladder presenting with hematuria. Computed tomographic angiography showed dilated varices around the neobladder which were successfully embolized. To the best of our knowledge, this is the first report case of variceal bleeding in a neobladder successfully managed with the combination of TIPS (transjugular intrahepatic portosystemic shunt) procedure and embolization.

    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.

    The main aims were to explore time trends in the management and outcome of patients with rectal cancer in a national cohort and to evaluate the possible impact of national auditing on overall outcomes. A secondary aim was to provide population-based data for appraisal of external validity in selected patient series. Data from the Swedish ColoRectal Cancer Registry with virtually complete national coverage were utilized in this cohort study on 29 925 patients with rectal cancer diagnosed between 1995 and 2012. Of eligible patients, nine were excluded. During the study period, overall, relative and disease-free survival increased. Postoperative mortality after 30 and 90 days decreased to 1.7% and 2.9%. The 5-year local recurrence rate dropped to 5.0%. Resection margins improved, as did peri-operative blood loss despite more multivisceral resections being performed. Fewer patients underwent palliative resection and the proportion of non-operated patients increased. The proportions of temporary and permanent stoma formation increased. Preoperative radiotherapy and chemoradiotherapy became more common as did multidisciplinary team conferences. Variability in rectal cancer management between healthcare regions diminished over time when new aspects of patient care were audited. There have been substantial changes over time in the management of patients with rectal cancer, reflected in improved outcome. Much indirect evidence indicates that auditing matters, but without a control group it is not possible to draw firm conclusions regarding the possible impact of a quality control registry on faster shifts in time trends, decreased variability and improvements.

    Full Text Available BACKGROUND Mesh rectopexy is one of the accepted treatment options for rectal prolapse. We used polypropylene posterior mesh rectopexy for prolapse rectum. The aim of the study was to see demographic, clinical and functional outcome of posterior mesh rectopexy in our setup. MATERIALS AND METHODS The case report of 33 patients under gone posterior abdominal mesh rectopexy in MKCG medical college and hospital from 1st July 2012 to 1st July 2017 were reviewed retrospectively and the patients were followed up in surgical OPD/telephonic questionnaire. All patients had undergone standard posterior abdominal mesh rectopexy without the division of lateral ligaments with utmost care for prevention of bleeding and nerve damage. RESULTS Out of 33 cases of abdominal rectopexy, 12 (36% were males and 21 (64% were females. 27 (82% were within 61-80 years of age group. The most common symptoms were mass per annum (100% followed by incontinence for liquid stool and flatus 24 (72%. There was no operative mortality. The average hospital stay 7.8 days (5-11 days. The constipation (p=0.019 and incontinence (p=0.0165 were better postoperatively. There was 1 (3% partial recurrence of rectal prolapse in 91-year-old lady in 2 years follow up. CONCLUSION The recurrence rate as well as clinical and functional outcome of open abdominal mesh rectopexy seems to be satisfactory, however, long-term effect has to be seen.

    Although post-polypectomy bleeding is the most frequent complication after colonoscopic polypectomy, only few studies have investigated the incidence of bleeding prospectively. The aim of this study was to investigate the incidence of delayed post-polypectomy bleeding and its associated risk factors prospectively. Patients who underwent colonoscopic polypectomy at Kangbuk Samsung Hospital from January 2013 to December 2014 were prospectively enrolled in this study. Trained nurses contacted patients via telephone 7 and 30 days after polypectomy and completed a standardized questionnaire regarding the development of bleeding. Delayed post-polypectomy bleeding was categorized as minor or major and early or late bleeding. Major delayed bleeding was defined as a > 2-g/dL drop in the hemoglobin level, requiring hospitalization for control of bleeding or blood transfusion; late delayed bleeding was defined as bleeding occurring later than 24 h after polypectomy. A total of 8175 colonoscopic polypectomies were performed in 3887 patients. Overall, 133 (3.4%) patients developed delayed post-polypectomy bleeding. Among them, 90 (2.3%) and 43 (1.1%) patients developed minor and major delayed bleeding, respectively, and 39 (1.0%) patients developed late delayed bleeding. In the polyp-based multivariate analysis, young age ( 10 mm (OR 2.45; 95% CI 1.38-4.36) were significant risk factors for major delayed bleeding, while young age (< 50 years; OR 2.6; 95% CI 1.35-5.12) and immediate bleeding (OR 3.3; 95% CI 1.49-7.30) were significant risk factors for late delayed bleeding. Young age, aspirin use, polyp size, and immediate bleeding were found to be independent risk factors for delayed post-polypectomy bleeding.

  15. Scintigraphic pattern of small bowel bleeding

    International Nuclear Information System (INIS)

    Anshu Rajnish Sharma; Charan, S.; Silva, I.

    2004-01-01

    Introduction: Small intestine is the longest part of gastrointestinal tract. Intra-luminal haemorrhage occurring anywhere in its long and tortuous course is difficult to trace. It is relatively inaccessible to endoscopic evaluation. Upper GI endoscopy can see only up to distal duodenum, whereas colonoscope can view maximum of 30 centimeters of terminal ileum after negotiating the scope through ileo-caecal valve. Hence, localization of bleeding source from small bowel remains a difficult clinical problem. This group of patients can be evaluated with scintigraphy for localizing the site of bleeding before undergoing either angiography or surgery. To our best of knowledge, there is no study, which has utilized scintigraphy for evaluation of small bowel bleed exclusively. The present study has been designed to know the efficacy of 99mTc-RBC scintigraphy in detecting small bowel bleed and to know whether it can differentiate between jejunal and ileal bleeding ? Materials and methods: Thirteen patients presenting with lower gastrointestinal bleeding (malena) were enrolled for the study. In all cases, upper GI endoscopy (UGIE) was unremarkable. Colonoscopic examination was either negative or suspected bleeding occurring proximal to ileo-caecal valve. Thus, in these patients, it is presumed clinically that bleeding is originating from small bowel. Barium meal follow through (BMFT) studies, however, could not delineate any etiological lesion in these patients. There were 8 men and 5 women (mean age 48 years). All patients were anemic (Hb- 6 gm%) and mean 3 units of blood were transfused.These patients were subjected to Tc-99m labeled red blood cells scintigraphy (15 mci, in-vivo method) for localization of source of bleeding. The scintiscan was acquired in two phases. A first pass phase acquired at a rate of 2 seconds per frame for 60 seconds followed by acquisition of static abdominal images (500 K, 256 x 256 matrix) at 5 minutes intervals up to 90 minutes on LFOV gamma

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

    Science.gov (United States)

    Lirio, Richard A

    2016-01-01

    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.

    The main evidences of epidemiology, diagnostic imaging, pathology, surgery, radiotherapy, chemotherapy and follow-up are reviewed to optimize the routine treatment of rectal cancer according to a multidisciplinary approach. This paper reports on the knowledge shared between different specialists involved in the design and management of the multidisciplinary ESTRO Teaching Course on Rectal Cancer. The scenario of ongoing research is also addressed. In this time of changing treatments, it clearly appears that a common standard for large heterogeneous patient groups have to be substituted by more individualised therapies based on clinical-pathological features and very soon on molecular and genetic markers. Only trained multidisciplinary teams can face this new challenge and tailor the treatments according to the best scientific evidence for each patient

    Between 1984 and 1988, 206 patients were treated with pelvic radiotherapy after macroscopically complete surgery for rectal or (recto)sigmoid cancer. Depending on an estimation of the amount of small bowel in the intended treatment volume a total dose was, in general, 45 or 50 Gy. An additional boost of 10 Gy was given to 6 patients because of microscopically involved surgical margins. For tumor stage B a statistically significant trend (p=0.017) for higher local control with higher total dose was observed comparing patients treated with a total dose of 45 Gy or less, with more than 45 Gy but less than 50 Gy or with a total dose of 50 Gy or more. This finding illustrates the impact of total dose on local control for postoperative radiotherapy for rectal carcinoma. (author). 18 refs., 1 fig., 1 tab

  19. Management of rectal inflammatory myofibroblastic tumor recurrence

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Inflammatory myofibroblastic tumor (IMT is an uncommon mesenchymal neoplasm of intermediate malignant potential. It may occur in various anatomic locations, but rarely in the rectum. This is a case discussion of a 36-year-old male patient with IMT of the rectum. After the patient underwent radical surgery, recurrence was seen after 18 months. Because the tumor was very close to the surrounding tissue, palliative tumor resection was performed followed by concurrent chemo-radiation and non-steroidal anti-inflammatory drugs (NSAID. After 2-year follow-up, the patient has no evidence of recurrence or metastasis. Surgical resection is very important for patient with rectal IMT, even in relapse cases. And adjuvant chemoradiotherapy and NSAID are in favor of the incompletely resected tumors as our case. But perhaps, the adjuvant treatments could be helpful after radical resection of rectal tumor.

    1. Four-week-old A/HeJ mice were immunized by rectal antigen and at the age of 6 weeks the pelvic region was exposed to 2,000 rad of X-ray for two times. They were observed for a maximum period of 84 weeks. The first rectal cancer detected 36 days after irradiation was histologically found to be mucous-secreting-adenocarinoma. Within 32 weeks after irradiation, rectal cancer was observed in 21 (61.76%) of the 34 autopsied mice. During the entire period of observation, rectal cancer was observed in 25 (55.56%) of the 45 mice. 2. On the other hand, among the mice whose pelvic region was exposed to 2,000 rad for two times, the first cancer was observed 56 days after irradiation. Within 32 weeks after irradiation, rectal cancer was observed in 4 (18.18%) of the 22 autopsied mice. During the entire period of observation, rectal cancer was observed in 12 (33.33%) of the 36 mice. 3. In the group of 51 non-irradiated mice, no rectal cancer was observed. 4. The stainability of HID-AB stain of the histologically normal mucosa near irradiated site was compared between cancer induced cases and normal cases. In 22 (84.62%) mice among 26 with induced cancer and in 9 (45%) among 20 mice without cancer, rectal crypt with AB positive goblet cells could be observed. (author)

  7. Medical treatment for heavy menstrual bleeding

    Directory of Open Access Journals (Sweden)

    Yi-Jen Chen

    2015-10-01

    Full Text Available Heavy menstrual bleeding, or menorrhagia, is subjectively defined as a “complaint of a large amount of bleeding during menstrual cycles that occurs over several consecutive cycles” and is objectively defined as menstrual blood loss of more than 80 mL per cycle that is associated with an anemia status (defined as a hemoglobin level of <10 g/dL. During their reproductive age, more than 30% of women will complain of or experience a heavy amount of bleeding, which leads to a debilitating health outcome, including significantly reduced health-related quality of life, and a considerable economic burden on the health care system. Although surgical treatment might be the most important definite treatment, especially hysterectomy for those women who have finished bearing children, the uterus is still regarded as the regulator and controller of important physiological functions, a sexual organ, a source of energy and vitality, and a maintainer of youth and attractiveness. This has resulted in a modern trend in which women may reconsider the possibility of organ preservation. For women who wish to retain the uterus, medical treatment may be one of the best alternatives. In this review, recent trends in the management of women with heavy menstrual bleeding are discussed.

    To study endometrial histopathology in women presenting with postmenopausal bleeding. A two-year study from January 2003 to December 2004 of 100 cases of postmenopausal bleeding was conducted at Combined Military Hospital, Sialkot. The histopathology of endometrial biopsy specimens was done to find out the causes of postmenopausal bleeding in these ladies. All these 100 patients had confirmed menopause and the average age was 55 years and above. The most common histopathological diagnosis was senile endometrial atrophy (27%), followed by simple cystic hyperplasia in (17%). Three cases of simple cystic hyperplasia had coexistent ovarian tumors. Glandular hyperplasia without atypia was seen in 6% and with atypia in 4%. Other causes were endometritis (13%), endometrial polyps (8%), proliferative phase endometrium (6%) and secretary phase endometrium (5%). Endometrial carcinoma was seen in (6%) cases, (8%) biopsy specimens were non-representative. Although senile endometrial atrophy was most commonly found in these ladies but a significant percentage of endometrial hyperplasia and endometrial cancer implies the need for investigating all cases of postmenopausal bleeding. Bimanual examination and pelvic ultrasonography should be combined with endometrial sampling so that rare pelvic pathologies may not be missed. (author)

    Three types of rectal steroid preparation were labelled with Technetium 99 or Indium 111, and the extent of spread of each within the bowel was followed, immediately after administration and at 2hrs, using a gamma camera. Patients with ulcerative colitis were compared with controls. Results indicate that 'Colifoam' enema and 'Predsol' suppository act mainly in the rectum, but 'Predsol retention' enema spreads further into the colon, making it more useful for patients with extensive ulcerative colitis.

    2015-04-01

    The aim of this study was to evaluate the clinical utility of the new bleeding criteria, proposed by the Bleeding Academic Research Consortium (BARC), compared with the old criteria for determining the action of physicians in contact with bleeding events, after percutaneous coronary intervention (PCI). The BARC criteria were independently associated with an increased risk of 1-year mortality after PCI, and provided a predictive value, in regard to 1-year mortality. The standardized bleeding definitions will be expected to help the physician to correctly analyze the bleeding events, to select an optimal treatment, and to objectively compare the results of multiple trials and registries. All the patients undergoing PCI from June to September 2012 were prospectively enrolled. Patients who experienced a bleeding event were further classified, based on three different bleeding severity criteria: BARC, Thrombolysis In Myocardial Infarction (TIMI), and Global Use of Strategies To Open coronary arteries (GUSTO). The primary outcome was the occurrence of bleeding events requiring interruption of antiplatelet therapy (IAT) by physicians. A total of 376 consecutive patients were included in this study. Total bleeding events occurred in 46 patients (12.2%). BARC type ≥2 bleeding occurred in 30 patients (8.0%); however, TIMI major or minor bleeding, and GUSTO moderate or severe bleeding occurred in 6 (1.6%) and 11 patients (2.9%), respectively. Of the 46 patients, 28 (60.9% of patients) required IAT. On receiver-operating characteristic curve analysis, bleeding defined BARC type ≥2 effectively predicted IAT, with a sensitivity of 89.3%, and a specificity of 98.5% (pdefinition may be a more useful tool for the detection of bleeding with clinical relevance, for patients undergoing PCI.

    2012-01-01

    Objective: to determine the effectiveness of a rectal sedation protocol with sodium thiopental in children undergoing diagnostic imaging studies in a level-four-complexity health care facility. Materials and Methods: this case series observational study was developed between the months of January and March 2004 in the Fundacion clinica Valle del Lili. All pediatric patients between the ages of three months and eight years of age who underwent an imaging study were included. A dose of 25-40 mg/kg of sodium thiopental was administered rectally. Successful sedation was defined as one that allowed the successful completion of the study with the least number of motion artifacts. The features of the sedation and the adverse effects were evaluated. Results: the study population included 103 children with a median age of two years. The imaging studies were successfully concluded in 97% of the patients. The average total time until complete awakening was 2.9 hours. With respect to the interruption of sedation, we found statistically significant differences between the children who were kept awake the night before the procedure and those who were not. The most common adverse effect was diarrhea, which was recorded in 13 patients. Five of the patients required a supplemental dose of the sedative. There were two cases of increased salivation and one of vomiting, yet they resolved spontaneously. Conclusions: this rectal sodium thiopental protocol is a safe and effective procedure for the completion of diagnostic imaging studies in the pediatric population at our health care center.

    When total mesorectal excision (TME) is accurately performed, dysfunction, theoretically, does not occur. However, there are differences among individuals in the running patterns and the volumes of nerve fibers, and if obesity or a narrow pelvis is present, nerve identification is difficult. Currently, the rate of urinary dysfunction after rectal surgery ranges from 33% to 70%. Many factors other than nerve preservation play a role in minor incontinence. Male sexual function shows impotence rates ranging from 20% to 46%, while 20%-60% of potent patients are unable to ejaculate. In women, information on sexual function is not easily obtained, and there are more unknown aspects than in men. As urinary, sexual, and defecation dysfunction due to adjuvant radiotherapy have been reported to occur at a high frequency, the creation of a protocol that enables analysis of long-term functional outcome will be essential for future clinical trials. In the treatment of rectal cancer, surgeon-related factors are extremely important, not only in achieving local control but also in preserving function. This article reviews findings from recent studies investigating urinary, sexual, and defecation dysfunction after rectal cancer surgery and discusses questions to be studied in the future. (author)

    Purpose. To assess outcomes after microcoil embolization for active lower gastrointestinal (GI) bleeding. Methods. We retrospectively studied all consecutive patients in whom microcoil embolization was attempted to treat acute lower GI bleeding over 88 months. Baseline, procedural, and outcome parameters were recorded following current Society of Interventional Radiology guidelines. Outcomes included technical success, clinical success (rebleeding within 30 days), delayed rebleeding (>30 days), and major and minor complication rates. Follow-up consisted of clinical, endoscopic, and pathologic data. Results. Nineteen patients (13 men, 6 women; mean age ± 95% confidence interval = 70 ± 6 years) requiring blood transfusion (10 ± 3 units) had angiography-proven bleeding distal to the marginal artery. Main comorbidities were malignancy (42%), coagulopathy (28%), and renal failure (26%). Bleeding was located in the small bowel (n = 5), colon (n 13) or rectum (n = 1). Technical success was obtained in 17 patients (89%); 2 patients could not be embolized due to vessel tortuosity and stenoses. Clinical follow-up length was 145 ± 75 days. Clinical success was complete in 13 (68%), partial in 3 (16%), and failed in 2 patients (11%). Delayed rebleeding (3 patients, 27%) was always due to a different lesion in another bowel segment (0 late rebleeding in embolized area). Two patients experienced colonic ischemia (11%) and underwent uneventful colectomy. Two minor complications were noted. Conclusion. Microcoil embolization for active lower GI bleeding is safe and effective in most patients, with high technical and clinical success rates, no procedure-related mortality, and a low risk of bowel ischemia and late rebleeding

    The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair. Four presented primary arterioenteric fistulas, and one presented a secondary aortoenteric fistula. All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascular management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean follow-up time was 3 months (range, 1-6 months). All massive bleeding was controlled by occlusive balloon catheters. Four fistulas were successfully sealed with stent-grafts, resulting in a technical success rate of 80%. One patient was circulatory stabilized by endovascular management but needed immediate further open surgery. There were no procedure-related major complications. Mean hospital stay after the initial endovascular intervention was 19 days. Rebleeding occurred in four patients (80%) after a free interval of 2 weeks or longer. During the follow-up period three patients needed reintervention. The in-hospital mortality was 20% and the 30-day mortality was 40%. The midterm outcome was poor, due to comorbidities or rebleeding, with a mortality of 80% within 6 months. In conclusion, endovascular repair is an efficient and safe method to stabilize patients with life-threatening bleeding arterioenteric fistulas in the emergent episode. However, in this group of patients with severe comorbidities, the risk of rebleeding is high and further intervention must be considered

    A radiologic study of 4 biopsy-proven cases of the solitary rectal ulcer (S.R.U.) syndrome was undertaken. The radiologic findings of S.R.U. were rectal stenosis (one with ulcer), polypoid rectal mass, and multiple sub-mucosal defects with shallow ulcers. The S.R.U., which is benign and requires only dietetic treatment, must be differentiated from other more serious entities such as neoplastic and inflammatory bowel disease.

    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.

    Full Text Available Objectives: There is a little data about rectal administration of Ketamine as a postoperative analgesic, so we compared the efficacy of rectal ketamine with rectal acetaminophen, which is applied routinely for analgesia after painful surgeries like tonsillectomy. Methods: In this single-blinded comparative trial, we enrolled 70 children undergoing elective tonsillectomy, and divided them randomly in two groups. Patients received rectal ketamine (2 mg / kg or rectal acetaminophen (20 mg / kg at the end of surgery. The children′s Hospital of Eastern Ontario Pain scale was used to estimate pain in children. Also the vital signs, Wilson sedation scale, and side effects in each group were noted and compared for 24 hours. Results: The ketamine group had a lower pain score at 15 minutes and 60 minutes after surgery in Recovery (6.4 ± 0.8, 7.4 ± 1 vs. 7.1 ± 1.2, 7.8 ± 1.2 in the acetaminophen group, P < 0.05 and one hour and two hours in the ward (7.2 ± 0.7, 7 ± 0.5 vs. 7.9 ± 1.2, 7.5 ± 1.2 in the acetaminophen group, P < 0.05, with no significant differences till 24 hours. Dreams and hallucinations were not reported in the ketamine group. Systolic blood pressure was seen to be higher in the ketamine group (104.4 ± 7.9 vs. 99.8 ± 7.7 in the acetaminophen group and nystagmus was reported only in the ketamine group (14.2%. Other side effects were equivalent in both the groups. Conclusions: With low complications, rectal ketamine has analgesic effects, especially in the first hours after surgery in comparison with acetaminophen, and it can be an alternative analgesic with easy administration in children after tonsillectomy.

    Bleeding is a common problem in cancer patients, related to local tumor invasion, tumor angiogenesis, systemic effects of the cancer, or anti-cancer treatments. Existing bleeds can also be exacerbated by medications such as bevacizumab, nonsteroidal anti-inflammatory drugs (NSAIDs), and anticoagulants. Patients may develop acute catastrophic bleeding, episodic major bleeding, or low-volume oozing. Bleeding may present as bruising, petechiae, epistaxis, hemoptysis, hematemesis, hematochezia, melena, hematuria, or vaginal bleeding. Therapeutic intervention for bleeding should start by establishing goals of care, and treatment choice should be guided by life expectancy and quality of life. Careful thought should be given to discontinuation of medications and reversal of anticoagulation. Interventions to stop or slow bleeding may include systemic agents or transfusion of blood products. Noninvasive local treatment options include applied pressure, dressings, packing, and radiation therapy. Invasive local treatments include percutaneous embolization, endoscopic procedures, and surgical treatment.

    To determine the accuracy and usefulness of noninvasive continuous hemoglobin (Hb) monitoring in critically ill patients at risk of bleeding. An observational prospective study was made, comparing core laboratory Hb measurement (LabHb) as the gold standard versus transcutaneous hemoglobin monitoring (SpHb). Pediatric Intensive Care Unit of a tertiary University Hospital. Patients weighing >3kg at risk of bleeding. SpHb was measured using the Radical7 pulse co-oximeter (Masimo Corp., Irvine, CA, USA) each time a blood sample was drawn for core laboratory analysis (Siemens ADVIA 2120i). Sociodemographic characteristics, perfusion index (PI), pleth variability index, heart rate, SaO 2 , rectal temperature, low signal quality and other events that can interfere with measurement. A total of 284 measurements were made (80 patients). Mean LabHb was 11.7±2.05g/dl. Mean SpHb was 12.32±2g/dl (Pearson 0.72, R 2 0.52). The intra-class correlation coefficient was 0.69 (95%CI 0.55-0.78)(p<0.001). Bland-Altman analysis showed a mean difference of 0.07 ±1.46g/dl. A lower PI and higher temperature independently increased the risk of low signal quality (OR 0.531 [95%CI 0.32-0.88] and 0.529 [95%CI 0.33-0.85], respectively). SpHb shows a good overall correlation to LabHb, though with wide limits of agreement. Its main advantage is continuous monitoring of patients at risk of bleeding. The reliability of the method is limited in cases with poor peripheral perfusion. Copyright © 2016 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

    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

    Objectives: The largest radical resections in rectal cancer with significant morbidity and mortality (Urinary dysfunction, sexual dysfunction, permanent colostomy, etc.), on certain occasions and with high selectivity, they can be avoided with the implementation of local resections. Our intention is to assess the results of conservative treatment of rectal cancer early. Material and Methods: Between 01.01.89 and 31.12.09 14 consecutive patients were treated carriers rectal adenocarcinoma who had never received prior cancer treatment and a second simultaneous showed no neoplasia. The age of the patients presented a range between 44 and 72 years with a mean of 60.4 years; sex similarly partitioned and according to ECOG performance status was 0≤2. All patients were operated through a anal resection of which 4 were performed a submucosal tumor excision (T1) and 10 excision was entire rectal wall and tumor invaded the muscularis propria (T2). For this one type of surgery patients were selected the following criteria: tumor ≤6 cm. the anal verge, size ≤3 cm., GH I-II, vegetative, mobile, and T1-2, N0 by EER. After intervention, the pathological examination of the surgical specimen showed that 4 patients GH III, lymphovascular invasion and / or peri neural, or close surgical margins (+) (≤3 mm.) And T3, so underwent Miles operation (March 1 T1 and T2). Subsequently the rest of the patients (10) underwent concomitant radio chemotherapy. Radiation therapy was similar all using megavoltage photons (CO-60, 18mV) to the entire pelvic volume in a normofraccionamiento to complete 50.40 Gy (1.8 Gy / 28) using multiple fields (box technique). Chemotherapy was prepared 5FU + LV in the first patient (4), in following (4) was used 5FU continuous infusion (1st and 5th week) and the remaining (2) Capecitabine. Follow up was complete. Results: In our sample we extract local failure was 4 (29%), distant failure 3 (20%) and two local and distant failures (14%) so it follows that

    The study objective was to create an adult extracorporeal membrane oxygenation (ECMO) coagulopathic bleeding risk score. Secondary analysis was performed on an existing retrospective cohort. Pre-ECMO variables were tested for association with coagulopathic bleeding, and those with the strongest association were included in a multivariable model. Using this model, a risk stratification score was created. The score's utility was validated by comparing bleeding and transfusion rates between score levels. Bleeding also was examined after stratifying by nadir platelet count and overanticoagulation. Predictive power of the score was compared against the risk score for major bleeding during anti-coagulation for atrial fibrillation (HAS-BLED). Tertiary care academic medical center. The study comprised patients who received venoarterial or venovenous ECMO over a 3-year period, excluding those with an identified source of surgical bleeding during exploration. None. Fifty-three (47.3%) of 112 patients experienced coagulopathic bleeding. A 3-variable score-hypertension, age greater than 65, and ECMO type (HAT)-had fair predictive value (area under the receiver operating characteristic curve [AUC] = 0.66) and was superior to HAS-BLED (AUC = 0.64). As the HAT score increased from 0 to 3, bleeding rates also increased as follows: 30.8%, 48.7%, 63.0%, and 71.4%, respectively. Platelet and fresh frozen plasma transfusion tended to increase with the HAT score, but red blood cell transfusion did not. Nadir platelet count less than 50×10 3 /µL and overanticoagulation during ECMO increased the AUC for the model to 0.73, suggesting additive risk. The HAT score may allow for bleeding risk stratification in adult ECMO patients. Future studies in larger cohorts are necessary to confirm these findings. Copyright © 2017 Elsevier Inc.

    Apixaban is a new oral anticoagulant (NOACs: Novel Oral Anticoagulant), like dabigatran, rivaroxaban, and edoxaban. All of them are prescribed to patients with non valvular atrial fibrillation or venous thromboembolism, to replace warfarin, because of the lower probability of bleeding, however they can cause bleeding by themselves. Bleeding is an adverse event in patients taking anticoagulants. It is associated with a significant increase of morbidity and risk of death. However, these drugs should be used only for the time when anticoagulation is strictly required, especially when used for preventing deep vein thrombosis. Prolonged use increases the risk of bleeding. In the ARISTOTLE Trial Apixaban, compared with warfarin, was associated with a lower rate of intracranial hemorrhages and less adverse consequences following extracranial hemorrhage. Many physicians still have limited experience with new oral anticoagulants and about bleeding risk managment. We reviewed the available literature on extracranial and intracranial bleeding concerning apixaban. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

    Purpose: The purpose of this article was to investigate how exceeding specified rectal wall dose-volume constraints impacts on the risk of late rectal bleeding by using radiobiologic calculations. Methods and Materials: Dose-volume histograms (DVH) of the rectal wall of 250 patients with prostate cancer were analyzed. All patients were treated by three-dimensional conformal radiation therapy, receiving mean target doses of 80 Gy. To study the main features of the patient population, the average and the standard deviation of the distribution of DVHs were generated. The mean dose , generalized equivalent uniform dose formulation (gEUD), modified equivalent uniform dose formulation (mEUD) 0 , and normal tissue complication probability (NTCP) distributions were also produced. The DVHs set was then binned into eight classes on the basis of the exceeding or the fulfilling of three dose-volume constraints: V 40 = 60%, V 50 = 50%, and V 70 = 25%. Comparisons were made between them by , gEUD, mEUD 0 , and NTCP. Results: The radiobiologic calculations suggest that late rectal toxicity is mostly influenced by V 70 . The gEUD and mEUD 0 are risk factors of toxicity always concordant with NTCP, inside each DVH class. The mean dose, although a reliable index, may be misleading in critical situations. Conclusions: Both in three-dimensional conformal radiation therapy and particularly in intensity-modulated radiation therapy, it should be known what the relative importance of each specified dose-volume constraint is for each organ at risk. This requires a greater awareness of radiobiologic properties of tissues and radiobiologic indices may help to gradually become aware of this issue

    To assess whether oral sucralfate is effective in preventing late rectal injury in prostate cancer patients treated with radiotherapy. A double-blind, placebo-controlled, randomized trial was conducted across four institutions in Australia. Patients receiving definitive radiotherapy for prostate cancer were randomized to receive either 3 g of oral sucralfate suspension or placebo twice daily. Data on patients' symptoms were collected for 2 years, and flexible sigmoidoscopy was scheduled at 12 months after treatment. A total of 338 patients were randomized, of whom 298 had adequate follow-up data available for an analysis of late symptoms. Of the 298 patients, 143 were randomized to receive sucralfate and 155 placebo. The cumulative incidence of Radiation Therapy Oncology Group Grade 2 or worse late rectal toxicity at 2 years was 28% for placebo and 22% for the sucralfate arm (p = 0.23; 95% confidence interval for the difference -3% to 16%). Seventeen percent of patients in the sucralfate group had significant bleeding (Grade 2 or worse) compared with 23% in the placebo group (p = 0.18, 95% confidence interval -15% to 3%). No statistically significant difference was found between the two groups with respect to bowel frequency (p = 0.99), mucus discharge (p = 0.64), or fecal incontinence (p = 0.90). Sigmoidoscopy findings showed a nonstatistically significant reduction in Grade 2 or worse rectal changes from 32% with placebo to 27% in the sucralfate group (p = 0.25). This trial demonstrated no statistically significant reduction in the incidence of late rectal toxicity in patients randomized to receive sucralfate. However, this result was considered inconclusive, because the trial was unable to exclude clinically important differences in the late toxicity rates.

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

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    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.

    Successful management of acute gastrointestinal (GI) bleeding usually depends on accurate localization of the bleeding site. History and clinical findings are often misleading in determination of the site of hemorrhage. The widespread application of flexible endoscopy and selective arteriography now provide accurate diagnoses for the majority of patients bleeding from the upper GI tract, but lower GI bleeding still poses a serious diagnostic challenge. Endoscopy and barium studies are of limited value in examining the small bowel and colon in the face of active hemorrhage. Arteriography, although successful in many cases (3-5), has limitations. The angiographic demonstration of bleeding is possible only when the injection of contrast material coincides with active bleeding at a rate greater than 0.5 ml/min, and since lower GI bleeding is commonly intermittent rather than continuous, a high rate of negative angiographic examinations has been reported. The diagnosis of lower GI bleeding is usually easy to make. In contrast, localizing the site of bleeding may be extremely difficult. Using the techniques described the nuclear physician may be able to detect the bleeding site precisely. However, if the cautions detailed are not observed, the tracer studies will show GI bleeding, but not at the true bleeding site. This must be carefully understood and avoided. Done correctly, these tests can have a major impact on patient care

    Endometrial evaluation is generally indicated in cases presenting with abnormal uterine bleeding (AUB), especially in women more than 35 years of age. AUB encompasses a variety of presentation, for example, heavy menstrual bleeding, frequent bleeding, irregular vaginal bleeding, postcoital and postmenopausal bleeding to name a few. Many methods are used for the evaluation of such cases, with most common being sonography and endometrial biopsy with very few cases requiring more invasive approach like hysteroscopy. Endometrial aspiration is a simple and safe office procedure used for this purpose. We retrospectively analyzed cases of AUB where endometrial aspiration with Pipette (Medgyn) was done in outpatient department between January 2015 and April 2016. Case records (both paper and electronic) were used to retrieve data. One hundred and fifteen cases were included in the study after applying inclusion and exclusion criteria. Most cases were between 46 and 50 years of age followed by 41-45 years. No cases were below 25 or more than 65 years of age. Heavy menstrual bleeding was the most common presentation of AUB. Adequate samples were obtained in 86% of cases while 13.9% of cases' sample was inadequate for opinion, many of which were later underwent hysteroscopy and/or dilatation and curettage (D and C) in operation theater; atrophic endometrium was the most common cause for inadequate sample. Uterine malignancy was diagnosed in three cases. Endometrial aspiration has been compared with traditional D and C as well as postoperative histopathology in various studies with good results. Many such studies are done in India as well as in western countries confirming good correlation with histopathology and adequate tissue sample for the pathologist to give a confident diagnosis. No complication or side effect was noted with the use of this device. Endometrial aspiration is a simple, safe, and effective method to sample endometrium in cases of AUB avoiding risk of

Materials and Methods: We retrospectively analyzed cases of AUB where endometrial aspiration with Pipette (Medgyn was done in outpatient department between January 2015 and April 2016. Case records (both paper and electronic were used to retrieve data. Results: One hundred and fifteen cases were included in the study after applying inclusion and exclusion criteria. Most cases were between 46 and 50 years of age followed by 41–45 years. No cases were below 25 or more than 65 years of age. Heavy menstrual bleeding was the most common presentation of AUB. Adequate samples were obtained in 86% of cases while 13.9% of cases' sample was inadequate for opinion, many of which were later underwent hysteroscopy and/or dilatation and curettage (D and C in operation theater; atrophic endometrium was the most common cause for inadequate sample. Uterine malignancy was diagnosed in three cases. Discussion: Endometrial aspiration has been compared with traditional D and C as well as postoperative histopathology in various studies with good results. Many such studies are done in India as well as in western countries confirming good correlation with histopathology and adequate tissue sample for the pathologist to give a confident diagnosis. No complication or side effect was noted with the use of this device. Conclusion: Endometrial aspiration is a simple, safe, and

    Abnormal uterine bleeding (AUB) is the direct cause of a significant health care burden for women, their families, and society as a whole. Up to 30% of women will seek medical assistance for the problem during their reproductive years. To provide current evidence-based guidelines on the techniques and technologies used in endometrial ablation (EA), a minimally invasive technique for the management of AUB of benign origin. Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of both location in Canada and type of practice, as well as subspecialty expertise and general background in gynaecology. The committee reviewed all available evidence in the English medical literature, including published guidelines, and evaluated surgical and patient outcomes for the various EA techniques. Recommendations were established by consensus. Published literature was retrieved through searches of MEDLINE and The Cochrane Library in 2013 and 2014 using appropriate controlled vocabulary and key words (endometrial ablation, hysteroscopy, menorrhagia, heavy menstrual bleeding, AUB, hysterectomy). RESULTS were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies written in English from January 2000 to November 2014. Searches were updated on a regular basis and incorporated in the guideline to December 2014. Grey (unpublished) literature was identifies through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). This document reviews the evidence regarding the available techniques and technologies for EA

    This study sought to determine the relationship of bleeding disorders to iron deficiency anemia. Additionally, this study was undertaken to examine all current treatment modalities used in a menorrhagia clinic with respect to heavy menstrual bleeding management to identify the most effective options for menstrual management in the setting of an underlying bleeding disorder. DESIGN, SETTING, PARTICIPANT, INTERVENTION, AND MAIN OUTCOME MEASURES: Retrospective chart review of adolescent <21 years with heavy menstrual bleeding attending a multidisciplinary hematology-adolescent gynecology clinic. Information included demographics, bleeding diathesis, hematologic parameters, treatment, and the diagnosis was extracted from each chart. Subjects were grouped into two categories based on the diagnosis of a bleeding disorder. Hemoglobin level, iron deficiency anemia, and need for transfusion were compared between a bleeding disorder and no bleeding disorder group. Subjects were grouped into categories depending on hormonal modality and treatment success of the groups were compared. 73 subjects tested for a bleeding disorder. Of the subjects completing testing, 34 (46%) were diagnosed with a bleeding disorders. 39 (54%) subjects had heavy menstrual bleeding due to other causes. There was no significant difference in hemoglobin between those with and without a bleeding disorder. Iron deficiency anemia was significantly higher in subjects without bleeding disorder. When comparing hormone therapy success, the levonorgestrel IUD (LNG-IUD) (89%) had the highest rate of menstrual suppression followed by norethindrone acetate 5-10mg/day (83%), and the transdermal patch (80%). All subjects using both tranexamic acid and hormonal therapy had 100% achievement of menstrual suppression. A high frequency of bleeding disorder was found in those tested. Subjects with a bleeding disorder were less likely to present with severe anemia requiring blood transfusion and less likely to have iron

    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

    To show a new complication after deep sclerectomy (DS). We described two eyes of two patients with open-angle glaucoma and cataract who were operated on of an uneventful phacoemulsification and DS with SK-gel implantation. Bleeding during gonioscopic examination occurred in both eyes 7 and 8 months after combined surgery. The blood originated from the vessels around the Descemet window, and was probably due to manipulation or rocking of the goniolens. Pressure was immediately applied to the gonioscopic lens and the hyphema was interrupted. These cases show the presence of new vessels around the Descemet window after DS with SK-gel. Bleeding from the Descemet window vessels can occur during gonioscopy even months after DS. We recommend conducting a careful gonioscopic examination in patients who have undergone DS to avoid this complication.

    In this study we investigated the effect of post-transcatheter aortic valve implantation (TAVI) bleeding (per Valve Academic Research Consortium-2 [VARC-2] bleeding criteria) on 30-day postoperative mortality and examined the correlation between pre- or intraoperative variables and bleeding. Multiple electronic literature databases were searched using predefined criteria, with bleeding defined per Valve Academic Research Consortium-2 criteria. A total of 10 eligible articles with 3602 patients were included in the meta-analysis. The meta-analysis revealed that post-TAVI bleeding was associated with a 323% increase in 30-day postoperative mortality (odds risk [OR]; 4.23, 95% confidence interval [CI], 2.80-6.40; P logistic regression analysis revealed that atrial fibrillation (AF) was independently correlated with TAVI-associated bleeding (OR, 2.63; 95% CI, 1.33-5.21; P = 0.005). Meta-regression showed that potential modifiers like the Society of Thoracic Surgeons (STS) score, mortality, the logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE), aortic valve area, mean pressure gradient, left ventricular ejection fraction, preoperative hemoglobin and platelet levels, and study design had no significant effects on the results of the meta-analysis. Post-TAVI bleeding, in particular, major bleeding/life-threatening bleeding, increased 30-day postoperative mortality. Transapical access was a significant bleeding risk factor. Preexisting AF independently correlated with TAVI-associated bleeding, likely because of AF-related anticoagulation. Recognition of the importance and determinants of post-TAVI bleeding should lead to strategies to improve outcomes. Copyright © 2016 Canadian Cardiovascular Society. Published by Elsevier Inc.

  7. Heavy menstrual bleeding: An update on management.

    2017-03-01

    Heavy menstrual bleeding (HMB) is defined as excessive menstrual blood loss (MBL) >80 mL per cycle, that interferes with a woman's physical, emotional, social wellbeing and quality of life. Aetiology is due to underlying uterine pathologies, coagulopathy, ovulation dysfunction, or iatrogenic. Up to 20% of women with HMB will have an underlying inherited bleeding disorder (IBD). Assessment of HMB should entail a menstrual and gynaecological history and a bleeding score to distinguish those women who require additional haematological investigations. A pelvic examination and ultrasound scan help to rule out presence of any underlying pathology. Management depends on the underlying cause and the woman's preference and her fertility wishes. Medical therapies include hormonal treatments; levonorgestrel-releasing intrauterine system (LNG-IUS) and combined hormonal contraceptives are most commonly used. Ulipristal acetate is an approved preoperative treatment for uterine fibroids, and has demonstrated efficacy in reducing MBL. Haemostatic therapies include tranexamic acid and DDAVP (1-deamino-8-D-arginine). DDAVP is used for HMB associated with certain IBDs. These therapies can be used in isolation or in combination with hormonal treatments. HMB associated with certain severe IBDs may require factor concentrate administration during menses to alleviate symptoms. Endometrial ablation is a minor surgical procedure that is associated with low operative morbidity and can be performed as an outpatient. Hysterectomy remains the definitive treatment of choice when medical therapies have failed and endometrial ablation is not suitable. Crown Copyright © 2017 Published by Elsevier Ltd.

    An objective method for determining the location of the cancer with respect to peritoneal reflection would be helpful to decide the treatment modality for rectal cancer. This study was designed to evaluate the accuracy and usefulness of rectal MRI to determine spatial relations between the peritoneal reflection and rectal cancer and to compare these with operative findings. Patients that underwent a rectal cancer operation after a rectal MRI check between November 2008 and June 2010 were considered for the study. The patients that received preoperative concurrent chemoradiation or trans-anal local excision were excluded. Fifty-four patients constituted the study cohort. By comparing surgical and radiologic findings, the accuracy for predicting tumour location in relation to the peritoneal reflection by rectal MRI in all patients was 90.7%. In terms of tumour location in relation to peritoneal reflection, the accuracy of rectal MRI was 93.5% in patients with a tumour located above the peritoneal reflection, 90.0% in patients with a tumour located on the peritoneal reflection, and 84.6% in patients with a tumour located below the peritoneal reflection (p=0.061). When the cohort was subdivided by gender, body mass index (BMI), operative findings, or tumour size, no significant difference was observed among subgroups. Rectal MRI could be a useful tool for evaluating the relation between rectal cancer and peritoneal reflection especially when tumour size is less than 8cm. Rectal MRI can provide information regarding the location of rectal cancer in relation to the peritoneal reflection for treatment planning purposes

    Fournier's gangrene (FG) is a rapid progressive bacterial infection that involves the subcutaneous fascia and part of the deep fascia but spares the muscle in the scrotal, perianal and perineal region. The incidence has increased dramatically, while the reported incidence of rectal cancer-induced FG is unknown but is extremely low. Pathophysiology and clinical presentation of rectal cancer-induced FG per se does not differ from the other causes. Only rectal cancer-specific symptoms before presentation can lead to the diagnosis. The diagnosis of rectal cancer-induced FG should be excluded in every patient with blood on digital rectal examination, when urogenital and dermatological causes are excluded and when fever or sepsis of unknown origin is present with perianal symptomatology. Therapeutic options are more complex than for other forms of FG. First, the causative rectal tumor should be removed. The survival of patients with rectal cancer resection is reported as 100%, while with colostomy it is 80%. The preferred method of rectal resection has not been defined. Second, oncological treatment should be administered but the timing should be adjusted to the resolution of the FG and sometimes for the healing of plastic reconstructive procedures that are commonly needed for the reconstruction of large perineal, scrotal and lower abdominal wall defects.

    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

    Full Text Available The treatment of rectal cancer has been improved a great deal within the last 20 years. Major progress has been made in the preoperative evaluation by introducing MRI- imaging as a basis for the further management. Neoadjuvant radiochemotherapy has been shown to be effective in downstaging of advanced tumours. The surgical technique has been improved in many respects.- Total mesorectal excision has reduced local recurrences, sphincter saving techniques such as low anterior resection and intersphincteric resection reduced the need for a permanent stoma to 10%-20%. Recently the introduction of minimal invasive techniques and the application of robotic systems have reduced the surgical trauma.

    2013-06-17

    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.

    Preliminary research suggests that rectally administered nonsteroidal antiinflammatory drugs may reduce the incidence of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). In this multicenter, randomized, placebo-controlled, double-blind clinical trial, we assigned patients at elevated risk for post-ERCP pancreatitis to receive a single dose of rectal indomethacin or placebo immediately after ERCP. Patients were determined to be at high risk on the basis of validated patient- and procedure-related risk factors. The primary outcome was post-ERCP pancreatitis, which was defined as new upper abdominal pain, an elevation in pancreatic enzymes to at least three times the upper limit of the normal range 24 hours after the procedure, and hospitalization for at least 2 nights. A total of 602 patients were enrolled and completed follow-up. The majority of patients (82%) had a clinical suspicion of sphincter of Oddi dysfunction. Post-ERCP pancreatitis developed in 27 of 295 patients (9.2%) in the indomethacin group and in 52 of 307 patients (16.9%) in the placebo group (P=0.005). Moderate-to-severe pancreatitis developed in 13 patients (4.4%) in the indomethacin group and in 27 patients (8.8%) in the placebo group (P=0.03). Among patients at high risk for post-ERCP pancreatitis, rectal indomethacin significantly reduced the incidence of the condition.

    DNA hypermethylation in gene promoter regions (CpG islands) is emerging as an important pathway in colorectal cancer tumourigenesis. Whilst genetic mutations have been associated with extramural vascular invasion (EMVI) in rectal cancer, no such association has yet been made with epigenetic factors. 100 consecutive neoadjuvant-naïve patients undergoing curative surgery for rectal were classified according to the presence or absence of EMVI on histopathological examination. DNA was extracted from tumours and subjected to bisulfite conversion and methylation-specific PCR to determine CIMP status (high, intermediate, or low; according to a validated panel of 8 genes). CIMP status was correlated with EMVI status, histopathological, clinical, and demographic variables, in addition to overall (OS) and disease free (DFS) survival. 51 patients were characterised as CIMP-low, 48 CIMP-intermediate, and one patient CIMP-high. EMVI-positivity was associated with CIMP-intermediate epigenotype (p CIMP-intermediate epigenotype and EMVI-positivity, and the subsequent disadvantage in pathological stage, requirement for adjuvant therapy and worse survival, tumour epigenotyping could potentially play an important role in personalising patients' cancer care. Further work is required to understand the mechanisms that underlie the observed effect, with the hope that they may provide novel opportunities for intervention and inform treatment decisions in rectal cancer.
