    Small bowel diverticulitis is a rare cause of an acute abdomen. Originating from acquired diverticula of the jejunum, less often of the ileum, or Meckel diverticulum, the symptoms are non-specific, simulating other acute inflammatory disorders, such as appendicitis, cholecystitis or colonic diverticulitis. The diagnosis of small bowel diverticulitis is solely based on radiologic findings, with computed tomography (CT) regarded as the method of choice. In recent years, a number of case reports have described the spectrum of the CT features in acute small bowel diverticulitis and its dependence on the severity of the inflammatory process. Typical findings are an inflamed diverticulum, inflammatory mesenteric infiltration, extraluminal gas collection and mural edema of adjacent small bowel loops with resultant separation of bowel loops. An enterolith is rarely found in an inflamed diverticulum. Complications include abscesses, fistulae, small bowel obstruction and free perforation with peritonitis. Small bowel diverticulitis can be a diagnostic problem if it involves the terminal ileum or Meckel's diverticulum. For preoperative confirmation of the presumed diagnosis of small bowel diverticulitis on CT, an enteroclysis for acquired diverticula or a technetium scan for Meckel's diverticulum should be performed. We present the CT findings in three patients of acute small bowel diverticulitis, two affecting the jejunum and one a Meckel's diverticulum. (orig.) [de

    The objective of this article is to review the pathophysiology of acute small bowel diseases, and to correlate the mechanisms of disease with computed tomography (CT) findings. Disease entities will be classified into the following: immune mediated and infectious causes, vascular causes, mechanical causes, trauma, and others. Having an understanding of acute small bowel pathophysiology is a useful teaching tool, and can lead to imaging clues to the most likely diagnosis of acute small bowel disorders.

    Small bowel obstruction (SBO) is a common presentation to emergency abdominal surgery. The most frequent causes of SBO are congenital, postoperative adhesions, abdominal wall hernia, internal hernia and malignancy. A 27-year-old woman was hospitalized because of acute abdominal pain, blockage of gases and stools associated with vomiting. Abdominal computed tomography showed an acute small bowel obstruction without any obvious etiology. In view of important abdominal pain and the lack of clear diagnosis, an explorative laparoscopy was performed. Diagnostic of pelvic inflammatory disease was established and was comforted by positive PCR for Chlamydia Trachomatis. Acute small bowel obstruction resulting from acute pelvic inflammatory disease, emerging early after infection, without any clinical or X-ray obvious signs was not described in the literature yet. This infrequent acute SBO etiology but must be searched especially when there is no other evident cause of obstruction in female patients. Early laparoscopy is mostly advised when there are some worrying clinical or CT scan signs.

    Full Text Available Gossypiboma, an infrequent surgical complication, is a mass lesion due to a retained surgical sponge surrounded by foreign body reaction. In this case report, we describe gossypiboma in the abdominal cavity which was detected 14 months after the hysterectomy due to acute abdominal pain. Gossypiboma was diagnosed by computed tomography (CT. The CT findings were a rounded mass with a dense central part and an enhancing wall. In explorative laparotomy, small bowel loops were seen to be perforated due to inflammation of long standing gossypiboma. Jejunal resection with end-to-end anastomosis was performed. The patient was discharged whithout complication. This case was presented to point to retained foreign body (RFB complications and we believed that the possibility of a retained foreign body should be considered in the differential diagnosis of who had previous surgery and complained of pain, infection, or palpable mass.

  7. The research progress of acute small bowel perforation

    Full Text Available This article reviews the various aetiologies of small bowel perforations and their management. In addition to the well-known aetiologies such as trauma, inflammation and circulatory disorders, several new causes of small bowel perforation have been described in recent years. The spectrum reaches from iatrogenic perforations during laparoscopic surgery or enteroscopies to drug-induced perforations with new anticancer agents. The management of small bowel perforations requires a concept consisting of the safe revision of the leaking bowel and the treatment of the peritonitis. Depending on the local situation and the condition of the patient, several treatment options are available. The surgical management of the bowel leak can range from a simple primary closure to a delayed restoration of bowel continuity. When the condition of the bowel or patient is frail, the risk of a failure of a closure or anastomosis is too high, and the exteriorization of the bowel defect as a primary measure is a safe option. The treatment of the peritonitis is also dependent on the condition of the patient and the local situation. Early stages of peritonitis can be treated by a simple peritoneal lavage, either performed by laparoscopy or laparotomy. Severe forms of peritonitis with multi-organ failure and an abdominal compartment syndrome need repeated peritoneal revisions. In such cases, the abdomen can only be closed temporarily. Different technical options are available in order to overcome the difficult care of these patients.

    Full Text Available Bone marrow mesenchymal stem cells (BMMSCs have shown immunosuppressive activity in transplantation. This study was designed to determine whether BMMSCs could improve outcomes of small bowel transplantation in rats.Heterotopic small bowel transplantation was performed from Brown Norway to Lewis rats, followed by infusion of BMMSCs through the superficial dorsal veins of the penis. Controls included rats infused with normal saline (allogeneic control, isogeneically transplanted rats (BN-BN and nontransplanted animals. The animals were sacrificed after 1, 5, 7 or 10 days. Small bowel histology and apoptosis, cytokine concentrations in serum and intestinal grafts, and numbers of T regulatory (Treg cells were assessed at each time point.Acute cellular rejection occurred soon after transplantation and became aggravated over time in the allogeneic control rats, with increase in apoptosis, inflammatory response, and T helper (Th1/Th2 and Th17/Treg-related cytokines. BMMSCs significantly attenuated acute cellular rejection, reduced apoptosis and suppressed the concentrations of interleukin (IL-2, IL-6, IL-17, IL-23, tumor necrosis factor (TNF-α, and interferon (IFN-γ while upregulating IL-10 and transforming growth factor (TGF-β expression and increasing Treg levels.BMMSCs improve the outcomes of allogeneic small bowel transplantation by attenuating the inflammatory response and acute cellular rejection. Treatment with BMMSCs may overcome acute cellular rejection in small bowel transplantation.

    Full Text Available Esophageal pneumatosis is a rare condition with diverse potential etiologies including traumatic, mechanical, ischemic, obstructive respiratory, autoimmune, immunodeficient, and infectious causes. Here, we present a case of esophageal pneumatosis in the setting of upper gastrointestinal and small bowel ileus, diagnosed on computed tomography (CT, with acute resolution after nasogastric tube decompression. A patient presented to the emergency department with epigastric discomfort. CT of the abdomen/pelvis demonstrated intramural air in the mid-to-distal esophagus, consistent with esophageal pneumatosis, and diffuse dilatation of the visualized esophagus, stomach, and small bowel, consistent with an ileus. Patient was managed with nasogastric tube decompression and bowel rest. Subsequent esophagram did not demonstrate any evidence of perforation and a repeat CT of the abdomen/pelvis, performed 11 hours after initial diagnostic CT, demonstrated interval resolution of patient's esophageal pneumatosis, and improvement of patient's ileus.

    Full Text Available Acute portomesenteric venous thrombosis is a rare but life-threatening complication of laparoscopic surgery that has been described in literature. Prompt diagnosis and early initiation of treatment are vital to prevent life-threatening complications such as mesenteric ischemia and infarction. A 51-year-old lady had laparoscopic small bowel resection and primary anastomosis with ventral hernia repair 4 weeks earlier for partial small bowel obstruction. Her postoperative period was uneventful and she was discharged home. Four weeks after surgery she developed watery diarrhea and generalized abdominal pain for four-day duration. A computed tomography of the abdomen revealed portomesenteric venous thrombosis although a computed tomography of abdomen before surgery 4 weeks back did not show any portomesenteric venous thrombosis. We are reporting a case of acute portomesenteric venous thrombosis as a complication of laparoscopic surgery.

    Conclusion: Abdominal pain and distention of the abdomen are the most common symptoms and physical findings in patients presenting with acute mechanical small bowel obstruction (SBO. Worm (ascaridial obstruction is the most common cause of obstruction followed by postoperative adhesions. Although all patients were managed conservatively to start with, the operative rate in our series remained very high because it is very difficult to distinguish simple from strangulation obstruction on clinical, biochemical and/or radiological grounds with certainty.

    Aim: To evaluate frequency and clinical relevance of the 'small bowel faeces' sign (SBFS) on computed tomography (CT) in patients with and without small bowel obstruction (SBO) presenting with acute abdominal or acute abdominal and flank pain. Methods: Abdominal CTs of consecutive patients presenting to the emergency department with abdominal or flank pain over a 6 month period were retrospectively reviewed by six radiologists, independently, for the presence of the SBFS. Examinations with positive SBFS were further evaluated in consensus by three radiologists, blinded to the final diagnosis. The small bowel was graded as non-dilated ( 4 cm) dilated. The location of SBFS and presence of distal small bowel collapse indicative of SBO was recorded. Imaging findings were subsequently correlated with the final diagnosis via chart review and compared between patients with and without SBO. Results: Of 1642 CT examinations, a positive SBFS was found in 100 (6%) studies. Of 100 patients with a positive SBFS, 32 (32%) had documented SBO. The remaining 68 patients had other non-obstructive diagnoses. SBFS was located in proximal, central, distal and multisegmental bowel loops in one (3.1%), eight (25.0%), 21 (65.6%) and two (6.3%) patients with SBO, and in zero (0%), 10 (14.7%), 53 (77.9%) and five (7.4%) of patients without SBO (p < 0.273). The small bowel was non-dilated and mildly, moderately or severely dilated in one (3%), five (16%), 20 (62%) and six (19%) patients with SBO, and in 61(90%), seven (10%), zero (0%) and zero (0%) patients without SBO. Normal or mildly dilated small bowel was seen in all (100%) patients without SBO, but only in six (19%) of 32 patients with SBO (p < 0.0001). Moderate or severe small bowel dilatation was seen in 26 (81%) patients with SBO (p < 0.0001), but it was absent in patients without SBO. Distal small bowel collapse was found in 27 (84.4%) of 32 patients with SBO, but not in patients without SBO (p < 0.0001). A combination of SBFS

    The acute surgical unit (ASU) is a recently established model of care in Australasia and worldwide. Limited data are available regarding its effect on the management of small bowel obstruction. We compared the management of small bowel obstruction before and after introduction of ASU at a major tertiary referral centre. We hypothesized that introduction of ASU would correlate with improved patient outcomes. A retrospective review of prospectively maintained databases was performed over two separate 2-year periods, before and after the introduction of ASU. Data collected included demographics, co-morbidity status, use of water-soluble contrast agent and computed tomography. Outcome measures included surgical intervention, time to surgery, hospital length of stay, complications, 30-day readmissions, use of total parenteral nutrition, intensive care unit admissions and overall mortality. Total emergency admissions to the ASU increased from 2640 to 4575 between the two time periods. A total of 481 cases were identified (225 prior and 256 after introduction of ASU). Mortality decreased from 5.8% to 2.0% (P = 0.03), which remained significant after controlling for confounders with multivariate analysis (odds ratio = 0.24, 95% confidence interval 0.08-0.73, P = 0.012). The proportion of surgically managed patients increased (20.9% versus 32.0%, P = 0.003) and more operations were performed within 5 days from presentation (76.6% versus 91.5%, P = 0.02). Fewer patients received water-soluble contrast agent (27.1% versus 18.4%, P = 0.02), but more patients were investigated with a computed tomography (70.7% versus 79.7%, P = 0.02). The ASU model of care resulted in decreased mortality, shorter time to intervention and increased surgical management. Overall complications rate and length of stay did not change. © 2015 Royal Australasian College of Surgeons.

    Objective: To have a further study of the value of MSCT in diagnosing acute small bowel retrograde intussusception in adults by means of 64-slice-spinal CT. Methods: A 46-year-old female patient with the history of abdominal operation was found having acute mechanical small bowel obstruction through plain X-ray radiograph. 64-slice MSCT was performed afterwards (plain scan + 3 stage contrast scans). Hence, evidence is provided for operation. Results: Using the technique of MSCT for the patient can promptly approach the diagnosis of jejuno-jejunal intussusception with severe bowel obstruction; no small bowel tumor or other organic lesion found in this case. With the patient who has the history of abdominal operations, MSCT can predict the reason of adhesion causing bowel intussusception, and provide the evidence for operation; whereas MSCT with contrast media offers a further investigation of the blood supply to the bowels through SMA, and observation of blood circulation through the intussuscepting site, which represents venous congestion of intussusception. This case is a retrograde small bowel intussusception and confirmed with operation evidence. A greater amount of gas and fluid is accumulated between the dilated space of middle-distal portion of intussusceptum and intussuscipiens. Nevertheless, less gas at the proximal portion and that can be an important sign for retrograde intussusception. Conclusion: MSCT is a good choice of examination for diagnosis of adult's intussusception. As the literature mentioned the advantages of MSCT for observing the circulation of intussusceptum and whether the diagnosis is antegrade or retrograde intussusception is also essential. (authors)

  16. Acute small bowel obstruction as a result of a Meckel's diverticulum encircling the terminal ileum: A case report

    Full Text Available Abstract Background In the developed world, small bowel obstruction accounts for 20% of all acute surgical admissions. The aetiology for majority of these cases includes postoperative adhesions and herniae. However, a relatively uncommon cause is a Meckel's diverticulum. Although this diagnosis is primarily reported in the adolescent population, it should also be considered in adults. Case Presentation In the present report, we present a rare case where a fit and healthy 74-year-old gentleman, with no previous history of abdominal surgery, presented with the cardinal symptoms and signs of small bowel obstruction as the result of a Meckel's diverticulum encircling his terminal ileum. Initial investigations included a supine abdominal x-ray showing dilated loops of small bowel and computerised tomographic imaging of the abdomen, which revealed a stricture in the terminal ileum of unknown aetiology. At laparotomy, multiple loops of distended small bowel were seen from the duodeno-jeujenal junction to the terminal ileum, which was encircled by a Meckel's diverticulum. The Meckel's diverticulum was then divided to release the obstruction, mobilised and subsequently removed. Finally, the small bowel contents were decompressed into the stomach and the nasogastric tube aspirated, before returning the loops of bowel into the abdomen in sequence. The patient made a good postoperative recovery and was discharged home 5 days later. Conclusion This report highlights the importance of considering a Meckel's diverticulum as a cause of small bowel obstruction in individuals from all age groups and especially in a person with no previous abdominal pathology or surgery.

    Small bowel obstructions (SBOs) occur 300,000 times annually leading to $1.3 billion in cost. Approximately 20% of patients require a laparotomy to manage the obstruction and either prevent or treat intestinal ischemia. Early management may play a role in reducing these complications. Nasogastric decompression is commonly used for early management. Our primary objective was to determine if NGD was associated with lower rates of surgery, bowel ischemia or length of stay. We retrospectively enrolled 181 ED patients with SBO from 9/2013 to 9/2015 in order to determine if nasogastric decompression was associated with a reduction in rates of surgery, bowel ischemia or hospital length of stay. Our subject population was 46% female, median age of 60.27% of patients received surgery. Nasogastric decompression was used in 51% of patients. There was no association with a reduction in rates of surgery (p=0.20) or bowel resection (p=0.41) with patients receiving Nasogastric decompression, and no difference in baseline characteristics. Nasogastric decompression was associated with a two-day increase in hospital length of stay. Factors that were significantly associated with surgical exploration of SBO were: female (OR 2.32 (95% CI: 1.01-5.31)) and "definite SBO" on CT (OR 3.29 (95% CI: 1.18-9.20)). Abnormal vital signs, obstipation, and lab values were not predictors of surgery. Nasogastric decompression is not associated with a reduction in need for surgery or bowel resection, but is associated with a 2-day increase in median LOS. Women were more likely to receive surgery than men. Copyright © 2017 Elsevier Inc. All rights reserved.

    Purpose: A direct relationship between the volume of small bowel irradiated and the degree of acute small bowel toxicity experienced during concurrent 5-fluorouracil (5-FU)-based chemoradiotherapy for rectal carcinoma is well recognized but poorly quantified. This study uses three-dimensional treatment-planning tools to more precisely quantify this dose-volume relationship. Methods and Materials: Forty patients receiving concurrent 5-FU-based chemotherapy and pelvic irradiation for rectal carcinoma had treatment-planning CT scans with small bowel contrast. A median isocentric dose of 50.4 Gy was delivered using a posterior-anterior and opposed lateral field arrangement. Bowel exclusion techniques were routinely used, including prone treatment position on a vacuum bag cradle to allow anterior displacement of the abdominal contents and bladder distension. Individual loops of small bowel were contoured on each slice of the planning CT scan, and a small bowel dose-volume histogram was generated for the initial pelvis field receiving 45 Gy. The volume of small bowel receiving each dose between 5 and 40 Gy was recorded at 5-Gy intervals. Results: Ten patients (25%) experienced Common Toxicity Criteria Grade 3+ acute small bowel toxicity. A highly statistically significant association between the development of Grade 3+ acute small bowel toxicity and the volume of small bowel irradiated was found at each dose level. Specific dose-volume threshold levels were found, below which no Grade 3+ toxicity occurred and above which 50-60% of patients developed Grade 3+ toxicity. The volume of small bowel receiving at least 15 Gy (V 15 ) was strongly associated with the degree of toxicity. Univariate analysis of patient and treatment-related factors revealed no other significant predictors of severe toxicity. Conclusions: A strong dose-volume relationship exists for the development of Grade 3+ acute small bowel toxicity in patients receiving concurrent 5-FU-based chemoradiotherapy

    Herniation of abdominal viscera into the thorax may occur as a consequence of abnormal defects in the diaphragm. In adults, the most common condition relates to herniations through a weakened crural orifice via which the oesophagus normally traverses. These hiatus hernias are classified as types I-IV depending on the extent of visceral involvement. We present here a case of type IV hiatus hernia with massive mediastinal herniation of the small bowel, yet remarkable in that the stomach itself remained completely intra-abdominal. Gastric outlet obstruction occurred as a consequence of extrinsic proximal small bowel compression. To our knowledge this is the first reported case of paraoesophageal hernia exclusively involving small bowel, without involving any part of the stomach, and yet causing gastric outlet obstruction.

    Small bowel transplantations (SBT) are being increasingly performed to treat patients with irreversible intestinal failure or short-bowel syndrome. Histologic evaluation of small bowel allograft biopsies is important for the diagnosis of acute cellular rejection (ACR). Serotonin (5-hydroxytriptamin) is a biogenous amine of which up to 95% is present in the enterochromaffin cells of the gastrointestinal tract. The aim of our study was to analyze rejection and number of serotonin positive cells in the intestinal graft biopsy samples early after SBT in pigs. 24 pigs were used and divided into 4 groups. Group A, autologous SBT (n = 3) as a control group; group B, allogeneic SBT with tacrolimus monotherapy (n = 7); group C, allogeneic SBT immunosuppressed with tacrolimus and sirolimus (n = 8); and group D, without immunosuppression (n = 6). Observation period was 30 days. Mucosal biopsies were obtained on days 0, 3, 5, 7, 10, 14, 20, 28 after transplantation. ACR was classified according to standardized grading schema on a scale of indeterminate, mild, moderate, and severe. Serotonin positive cells were quantified as the number of positive cells in 20 high power fields. There were no significant differences in the number of serotonin positive cells and different grades of ACR. In our experiment the number of serotonin positive cells was not a sensitive marker of ACR in the early period after small bowel transplantation.

    Purpose: The relationship between volume of irradiated small bowel (VSB) and acute toxicity in rectal cancer radiotherapy is poorly quantified, particularly in patients receiving concurrent preoperative chemoradiotherapy. Using treatment planning data, we studied a series of such patients. Methods and Materials: Details of 41 patients with locally advanced rectal cancer were reviewed. All received 45 Gy in 25 fractions over 5 weeks, 3-4 fields three-dimensional conformal radiotherapy with daily 5-fluorouracil and folinic acid during Weeks 1 and 5. Toxicity was assessed prospectively in a weekly clinic. Using computed tomography planning software, the VSB was determined at 5 Gy dose intervals (V 5 , V 1 , etc.). Eight patients with maximal VSB had dosimetry and radiobiological modeling outcomes compared between inverse and conformal three-dimensional planning. Results: VSB correlated strongly with diarrheal severity at every dose level (p 5 and V 15 . Conclusions: A strong dose-volume relationship exists between VSB and acute diarrhea at all dose levels during preoperative chemoradiotherapy. Our constructed model may be useful in predicting toxicity, and this has been derived without the confounding influence of surgical excision on bowel function. Inverse planning can reduce calculated dose to small bowel and late NTCP, and its clinical role warrants further investigation

    The volume, distribution, and mobility of opacified pelvic small bowel (PSB) were determined by fluoroscopy and orthogonal radiographs in 150 consecutive patients undergoing pelvic irradiation. Various techniques including uteropexy, omental transposition, bladder distention, inclining the patient, and anterior abdominal wall compression in the supine and prone treatment position were studied for their effect on the volume and location of small bowel within the pelvis. Abdominal wall compression in the prone position combined with bladder distention was selected for further investigation because of its simplicity, reproducibility, patient comfort, and ability to displace the small bowel. Factors correlating with the volume of pelvic small bowel (PSB) included prior pelvic surgery, pelvic irradiation (XRT), and body mass index. After pelvic surgery, especially following abdominoperineal resection (APR), there was a greater volume of PSB which was also less mobile. The severity of acute gastrointestinal effects positively correlated with the volume of irradiated small bowel. Overall, 67% of patients experienced little or no diarrhea, 30% developed mild diarrhea, and no patient required treatment interruption. Late gastrointestinal effects correlated with the prior pelvic surgery and with the volume of small bowel receiving greater than 45 Gy. Small bowel obstruction was not observed in 75 patients who had no previous pelvic surgery. However, following pelvic surgery excluding APR, 2/50 patients and following APR, 3/25 patients developed small bowel obstruction.

    Diverticular disease of the small intestine is rare, especially when it is located in the jejunum. It is generally asymptomatic, but in some patients it may have complications such as acute diverticulitis with peritonitis, gastrointestinal bleeding or obstruction. In such cases, the recommended treatment is surgery. We report a 77-year-old patient with ileal Crohn’s disease with a long-standing inflammatory phenotype, who developed acute diverticulitis of the jejunum presenting a severe septic shock and secondary multiple-organ failure. It resolved with medical treatment and prolonged antibiotic therapy.

    Inflammatory changes of the intestine leading to acute abdomen could represent a frequent diagnostic challenge for radiologists actively involved in the emergency area. MDCT imaging findings needs to be evaluated considering the clinical history and symptoms and other abdominal findings that could be of help in differential diagnosis. Several protocols have been suggested and indicated in the imaging of patient with acute intestine. However, a CT protocol in which the precontrast scanning of the abdomen is followed by i.v. administration of contrast medium using the 45-55 s delay could be effective for an optimal visualization of the bowel wall. It is important to learn to recognize how the intestine reacts to the injury and how it 'talks', in order to become aware of the different patterns of disease manifestation related to an acute intestinal condition, for an effective diagnosis of active and acute inflammatory bowel disease.

    Small bowel volvulus is a cause of acute abdomen and commonly occurs in neonates and young infants. Although it is rare in adults in the Western world,' it is a relatively common surgical emergency in the Middle East, India and Central Africa. It is associated with a mortality rate of 10-67% and, hence, it is important to make an early diagnosis to expedite surgical intervention. Computed tomography has become an important imaging modality in diagnosis and a number of signs have been recognized in a handful of documented case reports. We describe a case of small bowel volvulus that illustrates these important CT signs. Copyright (1999) Blackwell Science Pty Ltd

    Robertson, John M.; Lockman, David; Yan Di; Wallace, Michelle

    2008-01-01

    Purpose: Previous work has found a highly significant relationship between the irradiated small-bowel volume and development of Grade 3 small-bowel toxicity in patients with rectal cancer. This study tested the previously defined parameters in a much larger group of patients. Methods and Materials: A total of 96 consecutive patients receiving pelvic radiation therapy for rectal cancer had treatment planning computed tomographic scans with small-bowel contrast that allowed the small bowel to be outlined with calculation of a small-bowel dose-volume histogram for the initial intended pelvic treatment to 45 Gy. Patients with at least one parameter above the previously determined dose-volume parameters were considered high risk, whereas those with all parameters below these levels were low risk. The grade of diarrhea and presence of liquid stool was determined prospectively. Results: There was a highly significant association with small-bowel dose-volume and Grade 3 diarrhea (p ≤ 0.008). The high-risk and low-risk parameters were predictive with Grade 3 diarrhea in 16 of 51 high-risk patients and in 4 of 45 low-risk patients (p = 0.01). Patients who had undergone irradiation preoperatively had a lower incidence of Grade 3 diarrhea than those treated postoperatively (18% vs. 28%; p = 0.31); however, the predictive ability of the high-risk/low-risk parameters was better for preoperatively (p = 0.03) than for postoperatively treated patients (p = 0.15). Revised risk parameters were derived that improved the overall predictive ability (p = 0.004). Conclusions: The highly significant dose-volume relationship and validity of the high-risk and low-risk parameters were confirmed in a large group of patients. The risk parameters provided better modeling for the preoperative patients than for the postoperative patients

    In this review, we discuss the clinical and radiologic findings of small bowel diverticulosis, which is infrequently encountered during practice and far less common than colonic diverticulosis. Small bowel diverticulosis can present with a range of emergent symptomatic complications including diverticulitis, perforation, or hemorrhage. Here, we focus on the clinical features, pathogenesis, radiologic findings, and treatment of small bowel diverticulitis. Although not routinely considered in the differential diagnosis of an acute abdomen, prospective radiologic diagnosis of small bowel diverticulitis is important and can lead to conservative treatment thus preventing unnecessary exploratory laparotomy.

    To investigate the role of ischemia in the pathogenesis of small bowel strictures. Vascular anatomy of 39 small bowel strictures was studied using modified Spalteholtz method. Ten normal small bowel segments were studied as controls. 71.8% of small bowel strictures showed block in the mesenteric vessels (p=0.008). Subset analysis of tuberculous strictures showed block in the mesenteric vessels in 70.8% of strictures (p=0.0098). Ischemia plays a significant role in the pathogenesis of small bowel strictures. Mesenteric vasculopathy has a significant association with tuberculous strictures of the intestine.

    The diagnostic evaluation of small bowel Crohn's disease has changed dramatically over the last decade. The introduction of wireless capsule endoscopy, double balloon endoscopy and the introduction of newer therapeutic agents have changed the role of imaging in the small bowel. Additionally, advances in multidetector CT technology have further changed how radiologic investigations are utilized in the diagnosis and management of small bowel Crohn's disease. This article describes how we perform CT enteroclysis in the investigation of small bowel Crohn's disease and discusses the role of CT enteroclysis in the current management of small bowel Crohn's disease.

    Current therapeutic standard for locally advanced rectal cancer is the neoadjuvant radiochemotherapy with total mesorectal excision. Diarrhoea is the main acute side effect, induced by the dose to the small-bowel, frequently leading to a treatment modification. Aim of this study was to analyse the differences between the irradiated small-bowel volumes and the occurrence of acute diarrhea during combined radiochemotherapy for rectal cancer. 45 patients treated with a neoadjuvant radiochemotherapy (three-field box 50.4 Gy; Cetuximab, Capecitabine, Irinotecan) for locally advanced rectal cancer within a prospective phase I/II study were evaluated. Based on the dose-volume histograms, the small-bowel volumes receiving doses of 5, 10 … 45 Gy (V5, V10 …V45) were calculated and compared with the prospectively documented small- bowel toxicities. There was a statistically significant difference between irradiated small-bowel volumes and the severity of therapy related diarrhoea. The strongest validity concerning the risk of developing a grade 2-3 diarrhoea was seen at a dose level of 5 Gy (V 5) with a small-bowel volume of 291.94 cc. Patients with V 5 > 291.94 cc had significantly more often grade 2-3 diarrhoea, than patients with V5 below this cut-off value (82% vs. 29%; p bowel volume receiving 5 Gy should be limited to about 300 cc.

    Background: Acute intestinal obstruction due to tuberculosis is a common surgical problem in our community. Emergency surgery is usually required and surgical procedure depends upon the location and extent of the disease. The aim of this study was to determine the commonly involved region of intestine and different surgical procedures tailored. Methods: Thirty patients operated upon for acute intestinal obstruction in emergency with operative and histopathological findings suggestive of tuberculosis were included in the study. Demographic profile, operative findings, details of surgical procedure, complications and post-op hospital stay were recorded. The patients were followed for 6 months. Results: Intestinal tuberculosis is more common in young female, with male to female ratio of 1:1.5. Stricture of the small bowel was found in 50% of the cases. The next common finding was ileocaecal tuberculosis found in 40% of patients. Strictruplasty was performed in 11 (36.33%). The right hemicolectomy, limited ileocaecal resection and segmental bowel resection with end to end anastomosis were performed in four patients each. Other procedures were release of adhesions and bands in 4 patients, ileotransverse bypass in 1 patient and loop ileiostomy in 2 patients. Major complication in 10 patient and mortality rate was 10%. Conclusion: Because of non-specific clinical features, ignorance and malpractice intestinal tuberculosis presents late. Ileocecal tuberculosis is becoming less common as compared to small bowel strictures. Less radical surgery gives better results. Post operative complications and mortality are related to the perforation of the intestine at the time of surgery. (author)

    The irradiation of the pelvic abdominal cancers extends beyond the centre of the tumour and may induce actinic digestive lesions. The bowel and more rarely the small bowel -which is the subject-matter of our study- are concerned by those radiolesions that are favoured by therapeutic overdose, post-operative adhesions fastening the bows, radio-surgical or chemicostatic associations, and lastly by vascular or nutritive deficiencies. One may distinguish between two kinds of lesions, depending on the lapse of time before their coming out and on the symptoms. The early or acute types are characterized by a radio-mucitis and give an exsudative enteropathy with anorexia, vomiting, diarrhoea and loss of weight, of which the diagnosis is easy because it occurs during the irradiation and lessens at the end of the treatment. The late radiolesions of the small bowel are characterized by sclerosis and chronic endarteritis and, after a longlasting period of latency, give varied symptoms: disordered intestinal transit which sometimes is irreversible, perforation, fistula, syndrome of malabsorption, giving often rise to be mistaken for a recurrence of the cancer. The treatment varies whether the lesion is segmental or diffuse. In the first case, the failure of the medical means accounts for the surgical cutting away or the internal derivation; in the second case, the digestive mutilation which would result from an enlargement of the lesion commands to be more cautious and to call for the methods of parenteral feeding and digestive setting to rest [fr

    2005-01-01

    Background and purpose: To determine whether treatment prone on a belly-board significantly reduces the volume of small bowel irradiated in women receiving adjuvant radiotherapy for gynecologic cancer, and to prospectively study acute small bowel toxicity using an accepted recording instrument. Material and methods: Thirty-two gynecologic patients underwent simulation with CT scanning supine and prone. Small bowel was delineated on every CT slice, and treatment was prone on the belly-board using 3-5 fields-typically Anterior, Right and Left Lateral, plus or minus Lateral Boosts. Median prescribed dose was 50.4 Gy and all treatments were delivered in 1.8 Gy fractions. Concomitant Cisplatin was administered in 13 patients with cervical carcinoma. Comparison of small bowel dose-volumes was made between supine and prone, with each subject acting as their own matched pair. Acute small bowel toxicity was prospectively measured using the Common Toxicity Criteria: Version 2.0. Results: Treatment prone on the belly-board significantly reduced the volume of small bowel receiving ≥100; ≥95; ≥90; and ≥80% of the prescribed dose, but not ≥50%. This was found whether volume was defined in cubic centimeters or % of total small bowel volume. Of 29 evaluable subjects, 2 (7%) experienced 1 episode each of grade 3 diarrhoea. All other toxicity events were grade 2 or less and comprised diarrhoea (59%), abdominal pain or cramping (48%), nausea (38%), anorexia (17%), vomiting (10%). There were no Grade 4 events and no treatment days were lost due to toxicity. Conclusions: Treatment prone on a belly-board device results in significant small bowel sparing, during adjuvant radiotherapy for gynecologic cancer. The absence of Grade 4 events or Treatment Days Lost compares favorably with the published literature

    Abdominal radiotherapy is often limited by radiation-induced enteritis. Prostaglandin (PG) synthesis may play a role in the altered function of small bowel (SB) muscle and mucosa. Therefore, the authors have investigated the effects of X-radiation on PG synthesis, and other aspects of canine SB smooth muscle function. Canine SB received 9.38 Gy of 250 kVp X-radiation in situ. Electrodes were used to monitor spike burst and propagation of electrical activity in the SB muscle pre- and post-exposure. Animals were sacrificed prior to irradiation and at 1 and 4 days post-irradiation. Serum PG levels were assayed from mesenteric artery and vein samples, and SB muscle was removed for analysis of PG synthesis. SB muscle myoelectric activity decreased after irradiation until sacrifice (day 4). The PG synthesis in irradiated SB muscle at days 1 and 4 increased in PGE/sub 2/ and PGF/sub 2/α and in thromboxane A/sub 2/ metabolite, while the PGI/sub 2/ metabolite decreased. PG levels in venous blood indicate similar changes after passage through the intestine. Although causality is not established, radiation does induce changes in PG synthesis which correlate with changes in myoelectric activity (motility)

  4. Disturbances in small bowel motility.

    Quigley, E M

    2012-02-03

    Recently, the small intestine has become the focus of investigation as a potential site of dysmotility in the irritable bowel syndrome (IBS). A number of motor abnormalities have been defined in some studies, and include \\'clustered\\' contractions, exaggerated post-prandial motor response and disturbances in intestinal transit. The significance of these findings remains unclear. The interpretation of available studies is complicated by differences in subject selection, the direct influence of certain symptoms, such as diarrhoea and constipation, and the interference of compounding factors, such as stress and psychopathology. Dysmotility could also reflect autonomic dysfunction, disturbed CNS control and the response to heightened visceral sensation or central perception. While motor abnormalities may not explain all symptoms in IBS, sensorimotor interactions may be important in symptom pathogenesis and deserve further study.

    Small bowel capsule endoscopy (SBCE) was introduced 13 years ago by Given Imaging (Yokneam, Israel). It has become one of the most important investigational tools of the small bowel. The capsule is swallowed with water after a 12 h fast, propelled via peristalsis through the gastrointestinal tract and excreted naturally. A nonvideo patency capsule was developed to confirm functional patency of the gastrointestinal tract. Four additional companies have introduced competitive small bowel video capsules, some of which are Food and Drug Admistration (FDA) approved. Due to the easiness of the procedure, SBCE has become a first-line tool to detect small bowel abnormalities. The main indications for SBCE include obscure gastrointestinal bleeding, suspected Crohn's disease, small bowel tumors and practically any abnormal small bowel imaging. New indications are emerging like small bowel motility and monitoring of drug therapy and mucosal healing. The present review will describe the available capsules in the market, the procedure itself, present indications and future expectations. It will focus on the PillCam SB of Given Imaging as it is the one on which most of the literature is written. Over the past 10 years, SBCE has become a routine, first-line investigational tool of many small bowel pathologies.

    Full Text Available In the era of double balloon enteroscopy, capsule endoscopy, CT, and MRI enterography is transabdominal ultrasonography (TUS underestimated method for evaluation of small bowel pathology. As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries. Small intestine contrast ultrasonography with oral contrast fluid, as well as contrast enhanced ultrasonography with intravenous microbubble contrast also improves small bowel imaging. We present a review of small intestine pathology that should be detected during ultrasound examinations, discuss technical requirements, advantages and limitations of TUS, typical ultrasound signs of Crohn's disease, ileus, celiac disease, intussusception, infectious enteritis, tumours, ischemic and haemorrhagic conditions of small bowel. In the hands of experienced investigator, despite some significant limitations(obesity, meteorism, is transabdominal ultrasonography reliable, noninvasive and inexpensive alternative method to computerised tomography (CT and magnetic resonance imaging (MRI in small bowel examination.

    Authors designed a customized Small Bowel Displacement System(SBDS) to displace the small bowel from the pelvic radiation fields and minimize treatment-related bowel morbidities. From August 1995 to May 1996, 55 consecutive patients who received pelvic radiation therapy with the SBDS were included in this study. The SBDS consists of a customized styrofoam compression device which can displace the small bowel from the radiation fields and an individualized immobilization abdominal board for easy daily setup in prone position. After opacifying the small bowel with Barium, the patients were laid prone and posterior-anterior (PA) and lateral (LAT) simulation films were taken with and without the SBDS. The areas of the small bowel included in the radiation fields with and without the SBDS were compared. Using the SBDS, the mean small bowel area was reduced by 59% on PA and 51% on LAT films (P=0.0001). In six patients (6/55, 11%), it was possible that no small bowel was included within the treatment fields. The mean upward displacement of the most caudal small bowel was 4.8 cm using the SBDS. Only 15% (8/55) of patients treated with the SBDS manifested diarrhea requiring medication. The SBDS is a novel method that can be used to displace the small bowel away from the treatment portal effectively and reduce the radiation therapy morbidities. Compliance with setup is excellent when the SBDS is used. (author)

    Full Text Available Accidental ingestion of foreign bodies are a common condition in clinical practice. However, small bowel perforation which dues to ingestion foreign bodies has been rarely seen. In this article, we report a case of small bowel perforation which dues to ingestion foreign body. A 80-year-old female patient, presenting with complaints of acute abdomen, was admitted to the emergency department. She denied abdominal pain, nausea and vomiting. The patient had tenderness and defense on the right lower quadrant. Contrast enhanced abdominal computed tomography has been used on the patient's diagnosis. This revealed small bowel perforation due to the ingestion of foreign body. The patient was operated emergency. A microperforation due to fish bone was detected on the terminal ileum. The patient underwent debridement and primary repair. The patient was discharged postoperative 7th day without problem. Bowel perforation due to the ingestion of foreign bodies should be considered in the differential diagnosis of acute abdomen. Keywords: Foreign body, Small intestine, Perforation

    Full Text Available A 28-year-old female with history of chest wall extraskeletal myxoid chondrosarcoma (EMC presented to the emergency department complaining of two weeks of lightheadedness and fatigue. Laboratories showed hemoglobin of 7.6 g/dL and a positive hemoccult test. Upper and lower endoscopies were unremarkable, and the patient was discharged after blood transfusion. The next day she returned to the ED with left-sided weakness and perioral numbness. Brain CT scan revealed a 6 cm right frontal mass with midline shift and edema that required urgent craniotomy with resection of a hemorrhagic tumor. The patient continued dropping her hemoglobin, and CT scans showed a rounded 3 cm small bowel mass in the mid ileum. Repeat upper endoscopy revealed a 2 × 2 cm ulcerated mass in the fourth portion of the duodenum. The patient was taken to the operating room and was found to have two lesions; one in the distal duodenum and a second one in the mid ileum causing small bowel intussusception. Pathology was consistent with metastatic EMC grade 2/3, involving the bowel and mesenteric fat. Extraskeletal myxoid chondrosarcoma (EMC is a rare soft-tissue sarcoma with unique features that distinguishes, it from other sarcomas. It has been often described as a low-grade sarcoma although there are certain characteristics like high mitotic activity and the presence of focal regions of Ki67 staining above 25% that correlate with aggressive behavior of the tumor. This is the first case of EMC metastatic to the small bowel to be reported to the medical community.

    Effective clinical imaging of the small intestine is accomplished only with methods capable of accurately demonstrating bowel morphology. The two major approaches to barium enema examination of this segment of gut - orally and enteroclysis - will be described and illustrated with short videotape presentations. Pursued vigorously and with interest, both methods can yield excellent results in an efficient manner. Careful execution of the examination rather than use of a particular methodology is probably the most important factor in realizing such results. However, each method has its advantages and disadvantages, and these will be presented and discussed. A cursory small bowel examination has no role in modern medicine. Radiologists assume primary responsibility for the diagnostic evaluation of the small bowel and should strive to refine and advance the accuracy of the examination

    Full Text Available Vast majority of bowel obstruction is due to postoperative adhesions, malignancy, intestinal inflammatory disease, and hernias; however, knowledge of other uncommon causes is critical to establish a prompt treatment and decrease mortality. Xanthomatosis is produced by accumulation of cholesterol-rich foamy macrophages. Intestinal xanthomatosis is an uncommon nonneoplastic lesion that may cause small bowel obstruction and several cases have been reported in the English literature as obstruction in the jejunum. We report a case of small intestinal xanthomatosis occurring in a 51-year-old female who presented with one day of copious vomiting and intermittent abdominal pain. Radiologic images revealed jejunal loop thickening and inflammatory changes suggestive of foreign body obstruction, diagnostic laparoscopy found two strictures at the jejunum, and a pathologic examination confirmed a segmental small bowel xanthomatosis. This case illustrates that obstruction even without predisposing factors such as hyperlipidemia or lymphoproliferative disorders.

    In recent years, there has been renewed interest in small bowel imaging using a variety of radiologic or endoscopic techniques. This article gives an overview and comparison of old and new techniques used in small bowel imaging. New imaging methods as computed tomography (CT), CT enteroclysis (CTEc), CT enterography (CTEg), ultrasound (US), contrast-enhanced ultrasound (CEUS), US enteroclysis, US enterography, magnetic resonance imaging (MRI), MR enteroclysis (MREc) and MR enterography (MREg) are compared with the older techniques such as small- bowel follow- through (SBFT), conventional enteroclysis (CE) and endoscopic techniques including push enteroscopy, ezofagogastroduodenoscopy (EGD), sonde enteroscopy, ileocolonoscopy, double-balloon enteroscopy, intraoperative enteroscopy and wireless capsule enteroscopy (WCE). Systematic scan of Pubmed, Medline, Ovid, Elsevier search engines was used.. Additional information was found through the bibliographical review of relevant articles. SBFT has only secondary role in small bowel imaging. US is still the method of choice in imaging for pediatric populations. US and CEUS are also accepted as a method of choice especially in inflammatory cases. CE has been replaced by new cross - sectional imaging techniques (CTEc/CTEg or MREc/MREg). CTEc combines the advantages of CT and CE. MREc combines the advantages of MRI and CE. Some authors prefer CTEg or MREg with peroral bowel preparation and they strictly avoid nasojejunal intubation under fluoroscopic control. MREc has better soft tissue contrast, showing it to be more sensitive in detecting mucosal lesions than CTEc in inflammatory diseases. CTEg/MREg are techniques preferred for patients in follow-up of the inflammatory diseases. The radiologic community is not unanimous however about their role in the imaging process. CTEc/MREc as well as CTEg/MREg are superior to endoscopic methods in the investigation of small-bowel tumors. WCE gives unparalleled imaging of the mucosal

    Full Text Available Chronic low back pain is one of the leading chief complaints affecting adults in the United States. As a result, this increases the percentage of patients that will eventually undergo surgical intervention to alleviate debilitating, chronic symptoms. A 37-year-old woman presented ten hours postoperatively after a lumbar laminectomy with an acute abdomen due to the extraordinarily rare complication of small bowel injury secondary to deep surgical penetration.

    Laparoscopic treatment of small bowel obstruction has many reported advantages, yet it is infrequently performed. Criticisms include reduced working space, difficult abdominal access, and bowel injury. The experience with laparoscopic treatment of small bowel obstruction to determine its safety has been reviewed. Nineteen patients underwent laparoscopic treatment of small bowel obstruction. A cut-down technique was used for abdominal access and avoided manipulation of dilated bowel. The average number of prior operations was 1.4. The average size of maximally dilated bowel was 3.5 cm, including 6 patients whose diameter was greater than 4 cm. Laparoscopic treatment was successful in 16 patients; 3 patients required laparotomy. There were no complications from abdominal access and no iatrogenic bowel injuries. This series demonstrated that abdominal access and relief of bowel obstruction can be safely performed laparoscopically in patients with complex small bowel obstruction. Neither massively dilated bowel nor multiple previous abdominal operations precluded safe conduct of the operation laparoscopically.

    The small bowel (SB) represents the most important dose-limiting structure in pelvic radiotherapy (RT). However, we observed that the majority of rectal cancer patients who received preoperative pelvic intensity modulated RT (IMRT) developed acute tenesmus without watery diarrhea. The objective of this study is to determine if the RT dose to SB affects the acute lower gastrointestinal toxicity (ALGIT) in rectal cancer patients who received neoadjuvant concurrent chemotherapy-IMRT. We will also evaluate if patient and tumor factors affect the ALGIT. We retrospectively analyzed 63 rectal cancer patients that consecutively received preoperative IMRT (45 Gy for pelvis and 50 Gy for gross tumor in 25 fractions) with concurrent chemotherapy (oxaliplatin 130 mg/m(2) on day 1 and capecitabine 825 mg/m(2), twice per day from day 1 to day 14, week 1 and 4) between May 2012 and May 2013. The ALGIT was assessed with Common Terminology Criteria for Adverse Events version 3. The patients were stratified into two groups (with and without grade ≥2 ALGIT). The effect of SB volume receiving 5 to 40 Gy (V5 to V40) at a 5 Gy interval dose level on grade ≥2 ALGIT was evaluated. The volume of small bowel is defined as the volume of the small bowel loop. Other factors evaluated include patient's age and gender, tumor size and location and preexisting number of daily bowel movements. Overall, grade ≥2 ALGIT occurred in 57 % (36/63) patients. There was no significant difference between the two groups of patients (with and without grade ≥2 ALGIT) in SB V5 to V40, patient's age and gender, tumor location and preexisting number of daily bowel movements. There was a significant difference between the two groups of patients in tumor volume (with grade ≥2 ALGIT: 115.5 ± 85.5 cm(3) versus without grade ≥2 ALGIT: 58.5 ± 25.2 cm(3), p = 0.0001). Multivariate analysis revealed no association between the dose SB received (V5 to V40) and the grade ≥2 ALGIT after adjusting

    We herein report our experience regarding unusual causes of bowel obstruction to increase the awareness of surgeons regarding this disease. From 1991 to 2003, we had experience at the University affiliated hospitals, northern Jordan with 24 patients with small bowel obstruction resulting from unusual causes. We retrospectively reviewed the medical records of these patients with regards to the mode of presentation, cause of obstruction, radiological and operative findings, management and outcome. We recorded 15 patients who underwent previous abdominal surgery. Preoperative diagnosis was correct in only one patient with an internal hernia, but the abdominal CT scan suggested the diagnosis in 5 of the 9 patients who had the scan. The final diagnosis was internal hernias in 11 patients, foreign bodies in 5, ischemic strictures in 3, carcinoid tumors in 2, endometriosis in 2, and metastatic deposit from interstitial bladder carcinoma in one patient. Nine of the 12 patients with recurrent obstruction had either short course or recurrence obstruction during the same hospital admission. W carried out bowel resections in 15 patients (5 resections were due to bowel strangulation). Post operative death occurred in 4 patients. Awareness of these rare causes of intestinal obstruction even in patients with previous abdominal operation might improve the outcome. The tentative diagnosis of adhesion obstruction in patients with unusual obstructive etiology might lead to a higher rate of gangrenous complications. Rigorous preoperative evaluation including careful history and early abdominal CT may show the obstructive cause. (author)

    Full Text Available Amyloidosis is a pathological process which encompasses a spectrum of diseases that result from extracellular deposition of pathological fibrillar proteins. Clinical presentations vary depending on the organs involved. There is no documented case of amyloidosis presenting as small bowel encapsulation. A previously healthy 62-year-old man developed a small bowel obstruction in 1997. At surgery, a peculiar membrane encasing his entire small bowel was discovered. This appeared to have no vascularity and was removed without difficulty, exposing a grossly normal bowel. Histopathology revealed thick bands of collagen overlying the peritoneal surface, which was congo red positive and showed apple green birefringence. The findings were consistent with encapsulating peritonitis due to amyloidosis. There was no history or symptoms of any chronic inflammatory condition and he became symptom-free postoperatively. An abdominal fat pad biopsy failed to demonstrate amyloidosis. Endoscopic duodenal biopsies revealed classical primary amyloidosis. Quantitative immunoglobulins, lactate dehydrogenase, C3, C4 and beta-2 microglobulin were normal. Protein electrophoresis identified monoclonal paraprotein, immunoglobulin G lambda 3.7 g/L. Bone marrow biopsy and aspirate revealed only a mild plasmacytosis (5% to 10%. Echocardiogram and skeletal survey were normal. He had mild proteinuria. Complete blood count, C-reactive protein, calcium, albumin and total protein were normal. No specific therapy was instituted. In January of 1998 the patient remained asymptomatic with no gastrointestinal, cardiovascular or constitutional symptoms. He had developed nephrotic range proteinuria (3.95 g/24 h, microalbuminuria, hypoalbuminemia and a renal biopsy consistent with renal amyloidosis. In 1999 there was an increase in the monoclonal paraprotein (6.2 g/L. The remaining investigations were normal except for an echocardiogram which showed left ventricular hypertrophy but a normal

    We report a case of acute, small bowel obstruction secondary to intussusception caused by an enterolith from a jejunal diverticulum, in an elderly female with a history of chronic, intermittent abdominal pain. Diagnostic work-up of the patient included a computed tomographic (CT) scan which demonstrated the intussusception, but not the enterolith, which was characteristically radiolucent. A laparotomy was performed and the enterolith was found and delivered. A fistula between the gallbladder and small bowel was sought, but not found. Multiple diverticulae were found throughout the small bowel. Although small bowel diverticulosis is rare, it should be considered in the differential diagnosis of the acute abdomen and chronic abdominal pain, especially in those with known colonic diverticulosis, in whom this condition is more common.

    Small bowel (SB) diverticulosis is a rare disorder that may entail serious complications, including SB diverticulitis. Both are often missed in imaging. Magnetic resonance enterography/enteroclysis (MRE) is increasingly used to assess SB disease; awareness of the appearance of SB diverticulitis is essential to ensure appropriate management. Our aim was to systematically describe imaging characteristics of SB diverticulosis and diverticulitis in MRE. This retrospective, HIPAA-compliant study identified 186 patients with suspected SB diverticulosis/diverticulitis in medical databases of two tertiary medical centres between 2005 and 2011. Patients with surgically confirmed diagnoses of SB diverticulosis/diverticulitis were included. Two observers analyzed MR images for the presence, location, number, and size of diverticula, wall thickness, and mural and extramural patterns of inflammation. Seven patients were recruited. MRI analysis showed multiple diverticula in all (100 %). Diverticular size ranged from 0.5 to 6 cm. Prevalence of diverticula was higher in the proximal than the distal SB (jejunum 86 %, ileum 57 %, distal ileum43%). Diverticulitis occurred in 3/7 patients (43 %) showing asymmetric bowel wall thickening and focal mesenteric inflammation. SB diverticulitis demonstrates characteristic MRE imaging features to distinguish this rare disorder from more common diseases. Asymmetric, focal mesenteric and mural inflammation and presence of multiple diverticula are keys to diagnosis. • Small bowel diverticulosis and diverticulitis is rare and often missed in imaging • Acquired small bowel diverticula are variable in size and number • Small bowel diverticulitis demonstrates characteristic features on MR enterography/enteroclysis • A focal or segmental asymmetric small bowel inflammation should prompt the search for diverticula.

  7. Successful management of multiple small bowel perforations due to polyarteritis nodosa

    2014-01-01

    Full Text Available Classic Polyarteritis nodosa (PAN is a medium-sized vessel vasculitis that usually occurs in middle-aged men. One of the dramatic manifestations of PAN that requires surgical intervention is multiple small bowel perforations. Many studies have reported a high rate of mortality in PAN due to acute abdominal complications. We report here the case of multiple small bowel perforations in a 22-year-old man, who presented with an acute abdomen, and eventually, PAN was diagnosed. In our case, PAN led to multiple small bowel perforations and diffuse patchy necrosis. All perforations were primarily repaired and corticosteroids were prescribed. Using corticosteroid in patients with abdominal sepsis is injurious; however, laparostomy is the method we suggest, to achieve the purpose, including prevention of a short bowel and infection control. Our patient was discharged, well, after 48 days of hospitalization and referred to a rheumatologist.

  8. The prevention of radiation-induced small bowel complications

    Moderate dose pelvic radiotherapy is associated with a 5% severe complication risk related to the small bowel. Strictures and/or fistulation can occur many years after treatment. These complications are difficult to treat, and surgical treatment (excision, bypass) bears a significant morbidity risk. The risk of chronic diarrhoea or malabsorption may increase to 40%, depending on the irradiated small bowel volume. Late small bowel complications are generally irreversible due to vascular aetiology. Prevention of these complications can be achieved by limiting the volume of small bowel treated. Consequence for radiotherapeutic techniques in treatment for rectal cancer are multiple beam set-up, customised blocking based on visualisation of the small bowel in the treatment position, and the use of a special open table-top device that results in a small bowel shift from the treatment field.

  9. Scintigraphic pattern of small bowel bleeding

    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

    Gastrointestinal angiodysplasias recurrently bleed, accounting for 3-5% of obscure gastrointestinal bleeding. The advent of small bowel capsule endoscopy (SBCE) has led to an increased recognition of small bowel angiodysplasias (SBAs) but little is known about their etiology. Previous small cohorts and case reports suggest an equal gender incidence and associations with cardiovascular disease, renal impairment, and coagulopathies.

    Immunoglobulin G4 (IgG4)-related sclerosing disease is rare and is known to involve various organs. We present a case of histologically proven IgG4-related sclerosing disease of the small bowel with imaging findings on computed tomography (CT) and small bowel series. CT showed irregular wall thickening, loss of mural stratification and aneurysmal dilatation of the distal ileum. Small bowel series showed aneurysmal dilatations, interloop adhesion with traction and abrupt angulation.

    Objective: Evaluate the use of MDCT with 3D CT angiography (CTA) and CT portal venography (CTPV) reconstruction for the diagnosis of small bowel volvulus (SBV). Methods: Multiphasic MDCT findings in nine patients (seven males and two females, age range 2-70) with surgically proven SBV were retrospectively reviewed. Non-contrast and double phase contrast enhanced MDCT including 3D CTA and CTPV reconstruction were performed in all the patients. Two experienced abdominal radiologists evaluated the images and defined the location, direction and degree of SBV. Results: On axial MDCT images, all cases show segmental or global dilatation of small intestine. Other findings include circumferential bowel wall thickening in eight cases, halo appearance and hyperemia in seven cases, whirl sign in six cases, beak-like appearance in six cases, closed loops in six cases and ascites in one case. CTA/CTPV showed abnormal courses involving main trunks of superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in seven cases, with or without distortion of their tributaries. Normal course of SMA but abnormal course of SMV was seen in the other two cases. Of all the nine cases, whirl sign was seen in six cases and barber's pole sign in five cases. Dilated SMV was observed in eight cases and abrupt termination of SMA was found in one case. Compared with surgical findings, the location, direction and degree of SBV were correctly estimated in all cases based on CTA/CTPV. Conclusion: Multiphasic MDCT with CTA/CTPV reconstruction can play an important role in the diagnosis of SBV. The location, direction and degree of SBV can all be defined preoperatively using this method.

    About one-half of patients with meconium ileus (MI) present with a complication such as volvulus, atresia, meconium peritonitis or giant cystic meconium peritonitis. The treatment of these complications requires surgery. However, the preoperative diagnosis of complicated MI is difficult. We describe two neonates with complicated small-bowel obstruction, one with MI related to cystic fibrosis and the other not related to cystic fibrosis. In both, contrast enema depicted a spiral appearance of the distal small bowel, which at surgery proved to be the result of volvulus associated with antenatal bowel perforation. This appearance of the small bowel on contrast enema in this clinical setting has not been previously described. The recognition of this spiral appearance of the distal small bowel suggests the need for surgery. (orig.)

    2015-09-28

    Small bowel volvulus, which is torsion of the small bowel and its mesentery, is a medical emergency, and is categorized as primary or secondary type. Primary type often occurs without any apparent intrinsic anatomical anomalies, while the secondary type is common clinically and could be caused by numerous factors including postoperative adhesions, intestinal diverticulum, and/or tumors. Here, we report a rare case of a 60-year-old man diagnosed with small bowel volvulus using multidetector computed tomography (MDCT) angiography. Further discovery by laparotomy showed one jejunal diverticulum, longer corresponding mesentery with a narrower insertion, and a lack of mesenteric fat. This case report includes several etiological factors of small bowel volvulus, and we discuss the possible cause of small bowel volvulus in this patient. We also highlight the importance of MDCT angiography in the diagnosis of volvulus and share our experience in treating this disease.

    Full Text Available History of present illness: An elderly female with no history of prior abdominal surgeries presented to the emergency department (ED with acute onset of abdominal pain and distention. Upon arrival, she began having large volume bilious emesis. While waiting for a computed tomography (CT scan of her abdomen and pelvis, a point of care ultrasound (POCUS was performed which showed evidence of a small bowel obstruction (SBO. The patient had a nasogastric tube placed that put out over two liters of bilious contents. A subsequent CT scan confirmed the diagnosis of SBO from a left inguinal hernia and the patient was admitted to the surgical service. Significant findings: The POCUS utilizing the low frequency curvilinear probe demonstrates fluid-filled, dilated bowel loops greater than 2.5cm with to-and-fro peristalsis, and thickened bowel walls greater than 3mm, concerning for SBO. Discussion: Gastrointestinal obstruction is a common diagnosis in the ED, accounting for approximately 15% of all ED visits for acute abdominal pain.1 SBO accounts for approximately 80% of all obstructions.2 In the diagnosis of SBO, studies show that abdominal x-rays have a sensitivity of 66-77% and specificity of 50-57%,3 CT scans have a sensitivity of 92% and specificity of 93%,4 and ultrasound has a sensitivity of 88% and specificity of 96%.5 While CT scan remains a widely accepted modality for diagnosing SBO, ultrasound is more cost effective, well tolerated, does not involve ionizing radiation, and can be done in a timely manner at the patient’s bedside. Ultrasound can also identify transition points as well as distinguish between functional and mechanical obstruction.6 In addition to SBO, ultrasound can be used to diagnose external hernias, intussusception, tumors, superior mesenteric artery (SMA syndrome, foreign bodies, bezoars, and ascariasis.7

    The objective is to use multidetector computed tomography (MDCT) to differentiate phytobezoar impaction and small-bowel faeces in patients with small-bowel obstruction (SBO). We retrospectively reviewed 91 consecutive SBO patients with surgically proven phytobezoars (n = 31) or adhesion with small-bowel faeces (n = 60). Two readers blinded to the diagnosis recorded the following MDCT features: degree of obstruction, transition point, mesenteric fatty stranding, intraperitoneal fluid, air-fluid level, pneumatosis intestinalis, and portal venous gas. MDCT measurements of the food debris length, attenuation, luminal diameter, and wall thickness of the obstructed bowel were also compared. A higher grade of obstruction with an absence of mesenteric fatty stranding and intraperitoneal fluid was more commonly seen in the phytobezoar group than in the small-bowel faeces group (p < 0.01). The food debris length (phytobezoar, 5.7 ± 2.8 cm; small-bowel feces, 20.3 ± 7.9 cm, p < 0.01) and mean attenuation (phytobezoar, -59.6 ± 43.3 Hounsfield units (HU); small-bowel faeces, 8.5 ± 7.7 HU, p <0.01) were significantly different between the two groups. The ROC curve showed that food debris length <9.5 cm and mean attenuation value < -11.75 HU predicted phytobezoar impaction. MDCT features with measurements of the food debris length and mean attenuation assist the differentiation of phytobezoar impaction and small-bowel faeces. (orig.)

    Background: The role of CT enteroclysis is gaining on importance in the diagnostics of small bowel diseases. The aim of the study was to present own experiences in CT enteroclysis application, with the use of a 64-detector CT unit. Material/Methods: CT enteroclyses were performed in 60 patients: 53 with the suspicion of the Crohns disease, 2 suspected for carcinoid, 1 with suspicion of the fistula between the small bowel and the bladder, 2 suspected for the tumor of the ileo-caecal region, and in 1 case, the aim of examination was to carry out an evaluation of the postsurgical state of the bowel-bowel anastomosis. We used own endoscopic technique of catheter insertion into the bowel, which shortens the examination time and improves patients comfort. Results: The catheter was correctly introduced into the small bowel in 58 patients (endoscopy had to be repeated in 4 cases). Only 2 examinations failed, because patients refused repeated endoscopy. Radiological signs of the Crohns disease were found in 50 out of 53 patients. In the 3 remaining patients, the appearance of the small bowel was normal. In 5 non-Crohns disease patients, CT enteroclysis enabled a good visualization of the pathology (tumors, fistula). Conclusions: CT enteroclysis with the use of the 64-detector CT unit is a valuable method in the diagnostics of small bowel diseases. It could supplement or precede capsule endoscopy. (authors)

    To determine the frequency and significance of small-bowel intussusception identified in children on CT. All abdomen CT reports between July 1995 and April 2002 were reviewed to identify patients with small-bowel intussusception. Intussusceptions were identified as an intraluminal mass with a characteristic layered appearance and/or continuity with adjacent mesenteric fat. Ileocolic intussusceptions and intussusceptions related to feeding tubes were excluded. Imaging studies and medical records were reviewed. Twenty-five pediatric patients (16 boys, 9 girls; mean age 11.2 years) were identified with small-bowel intussusception on CT. No patient had a persistent intussusception requiring surgery. Fourteen had limited immediate repeat CT images as part of the same examination, ten of which demonstrated resolution of the CT abnormality. Follow-up CT [n=13 (6 within 24 h)], ultrasound (n=3), small-bowel follow-through (n=4) and surgery (n=3) showed no intussusception. In four patients with persistent symptoms, underlying pathology was identified requiring treatment (giardiasis, 2; small-bowel inflammation/strictures, 1; abscess and partial small-bowel obstruction after perforated appendicitis, 1). In 21 other patients, direct correlation of symptoms to CT abnormality was absent or questionable, no treatment was required, and there was no clinical or imaging evidence of persistence or recurrence. Most small-bowel intussusceptions identified in children by CT are transient and of no clinical significance. (orig.)

    Full Text Available Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma. A 33-year-old man was admitted to our hospital with three weeks history of colicky epigastric pain. Computed tomography revealed thickening of the ileal wall suggestive of intussusception. Colonoscopy revealed an ileocolic intussusception. Barium enema for reduction of ileocolic intussusception demonstrated a small bowel tumor in the ileum 15 cm proximal to the ileocecal valve. The intussusception was reduced, and the patient underwent partial resection of the ileum encompassing the small bowel tumor. Histological findings confirmed the diagnosis of lipoma of the small bowel. The patient made a satisfactory recovery and remains well.

    The purpose of this study was to evaluate whether affected bowel in Crohn's disease patients can be identified by observing decreased peristalsis (frozen bowel sign) using cine balanced steady-state free precession (cine BSSFP) images. 5 radiologists independently reviewed cine BSSFP sequences from randomized MR Enterography (MRE) exams for 30 normal and 30 Crohn's disease patients, graded overall small bowel peristalsis from slowest to fastest, and graded peristalsis for the most abnormal small bowel segment. Sensitivity and specificity of the frozen bowel sign for diagnosing Crohn's disease were calculated. T tests of the peristalsis difference between abnormal segments and overall small bowel were conducted. For 5 readers, the sensitivity and specificity of cine BSSFP of the frozen bowel sign for diagnosing Crohn's disease ranged from 70% to 100% and 87% to 100%, respectively. There were significant differences in peristalsis between abnormal small bowel segments and the overall small bowel for Crohn's patients, but not in the overall small bowel between normal-MRE patients and Crohn's disease patients. Abnormal Crohn's small bowel segments have significantly decreased peristalsis compared to normal small bowel, which can be identified using cine BSSFP sequences as the frozen bowel sign.

    The purpose of this study was to compare two osmotic carbohydrate sugar alcohols (mannitol 2.5% and sorbitol 2.5%, 2.0%, and 1.5% watery solutions) in combination with 0.2% locust bean gum (LBG) for small bowel distension for MR imaging. Small bowel distension was quantified on coronal 2D TrueFISP images by measuring the diameters of 16 small bowel loops in each of 12 healthy subjects (age range 31-55 years). Additionally, the grade of small bowel distension was rated qualitatively. Patient acceptance concerning nausea, vomiting, flatulence, and diarrhea was noted for each solution, and all results were compared by a Wilcoxon test or t test, respectively. The ingestion of water combined with LBG and either 2.5% mannitol or 2.0% sorbitol showed the best distension of the small bowel. The lowest side effect rate was observed following ingestion of sorbitol in a concentration of 2.0 and 1.5%. Based on these data, we recommend a combination of LBG and 2% sorbitol use for optimal bowel distension and minimal side effects resulting in enhanced patient acceptance. (orig.)

  10. Diverticular Disease of the Small Bowel

    Directory of Open Access Journals (Sweden)

    Francisco Emilio Ferreira-Aparicio

    2012-10-01

    Full Text Available A diverticulum is a bulging sack in any portion of the gastrointestinal tract. The most common site for the formation of diverticula is the large intestine. Small intestine diverticular disease is much less common than colonic diverticular disease. The most common symptom is non-specific epigastric pain and a bloating sensation. Major complications include diverticulitis, gastrointestinal bleeding, acute perforation, pancreatic or biliary (in the case of duodenal diverticula disease, intestinal obstruction, intestinal perforation, localized abscess, malabsorption, anemia, volvulus and bacterial overgrowth. We describe the clinical case of a 65-year-old female patient with a diagnosis on hospital admittance of acute appendicitis and a intraoperative finding of diverticular disease of the small intestine, accompanied by complications such as intestinal perforation, bleeding and abdominal sepsis. This was surgically treated with intestinal resection and ileostomy and a subsequent re-intervention comprising perforation of the ileostomy and stomal remodeling. The patient remained hospitalized for approximately 1 month with antibiotics and local surgical wound healing, as well as changes in her diet with food supplements and metabolic control. She showed a favorable clinical evolution and was dismissed from the hospital to her home. We include here a discussion on trends in medical and surgical aspects as well as early handling or appropriate management to reduce the risk of fatal complications.

    Small bowel diverticulosis of the jejunum and ileum is an uncommon finding with a prevalence rate of 0.2% to 1.3% at autopsy and 0.3% to 1.9% on small bowel studies. Diagnosis can be difficult because there are no pathognomonic features or clinical symptoms that are specific for small bowel diverticulosis. Though rare, it is critical to keep the possibility of small bowel diverticulosis in mind when evaluating cases of malabsorption, chronic abdominal pain, haemorrhage, perforation and intestinal obstruction, especially in patients with connective tissue disorders, a family history of diverticula and a personal history of colonic diverticulosis. Guidelines for the treatment of complicated small bowel diverticulosis are not clearly defined. However, the consensus in treatment is to do a small bowel resection with primary anastomosis. We report three interesting cases of jejunoileal diverticula that presented in an occult manner and later progressed to more emergent manifestations. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    To evaluate the CT findings of small bowel metastases from primary lung cancer. Of the 1468 patients with primary lung cancer between 1990 and 2000, 13 patients who had metastasis to the small intestine were collected. Of these 13 patients, nine who underwent CT scan were included for analysis. The pathologic diagnoses of primary lung cancer in these nine patients were squamous cell carcinoma in six, adenocarcinoma in two, and large cell carcinoma in one. CT scans were analyzed with regard to the site and patterns (intraluminal mass/bowel wall thickening/bowel implants) of metastatic masses, and the presence or absence of complication such as intussusception, obstruction, or perforation of the small bowel. The medical records of the patients were also reviewed retrospectively for evaluation of presenting abdominal symptom and time interval of metastases from initial diagnosis of lung cancer. Metastatic lesions were distributed throughout the small intestine: the duodenum in five, the jejunum in four, the ileum in six, and both jejunum and ileum in one patient. The size of metastatic masses of small bowel ranged from 1.3 cm to 5.0 cm (mean size, 2.6 cm) On CT, the small bowel was involved with intraluminal masses (mean size, 3.4 cm) in eight patients, diffuse wall thickening (mean thickness, 1.6 cm) in five, and bowel implants (mean size, 2.2 cm) in two. Complications occurred in seven patients, including intussusceptions without obstruction in two patients and with obstruction in two, obstruction without intussusceptions in two, and bowel perforation in one. Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients. CT helps in defining the extent and

  13. Mesenteric Air Embolism Following Enteroscopic Small Bowel Tattooing Procedure

    2012-01-01

    Full Text Available Double balloon enteroscopy (DBE is a revolutionary procedure in which the entire small bowel can be visualized endoscopically. DBE has the advantage of both diagnostic and therapeutic capabilities in the setting of small bowel neoplasms and vascular malformations. We present a unique case of a 76-year-old female who underwent small bowel DBE tattoo marking of a distal small bowel tumor complicated by development of severe abdominal pain postprocedure secondary to bowel air embolism into the mesenteric veins. Mesenteric air can be seen after other endoscopic procedures such as biopsy, mucosal clip placement and polypectomy, or following a colonoscopy. Mesenteric air embolism following small bowel tattooing procedure has not been previously reported in the literature. Mesenteric air when present may be attributed to mesenteric ischemia and can subject the patient to unnecessary surgical intervention if misdiagnosed. Thus, this report holds significance for the radiologist as computed tomography (CT findings of mesenteric air embolism must be evaluated in the context of appropriate clinical history before treatment decisions are made.

    The increasing frequency of use of CT in patients with acute abdomen is likely to improve the diagnosis of rarely occurring conditions/causes such as superior mesenteric vein thrombosis (MVT). Despite its severe consequences, MVT often presents with nonspecific clinical features. AD, a 64-year-old man was an emergency admission with vague abdominal discomfort of two weeks duration, acute upper abdominal pain, loose stools, fresh rectal bleeding and vomiting. A contrast enhanced abdominal CT showed thrombosis of the proximal portal vein and the entire length of the superior mesenteric vein (SMV) with small bowel ischaemia extending from the terminal ileum to the mid jejunal loops. Tests for paroxysmal nocturnal haemoglobinuria and Janus kinase 2 mutation yielded negative results. AD was readmitted seven months later with small bowel obstruction requiring segmental small bowel resection with end-to-end anastomosis. Abdominal CT had shown complete resolution of MVT but a small bowel stricture. Thrombosis limited to mesenteric veins results in earlier and more frequent development of infarction compared to portal combined with mesenteric venous thrombosis. Most patients may be successfully treated with anti-coagulation therapy alone. However, surgery may be required to deal with intestinal infarction or late sequela of MVT. This case demonstrates that MVT can be reversed by effective anticoagulation. However, the price paid for a mild to moderate effect on the bowel may be significant stricture later on. Patients escaping early bowel resection due to massive MVT leading to bowel infarction may still require resection later due to stricture. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    Objective: To investigate the value of MR enteroclysis with air infusion in the diagnosis of small bowel disease. Methods: Sixteen patients with suspected small bowel disease, but without acute inflammatory disease or bowel obstruction, received MR enteroclysis with air infusion. There were 12 males and 4 females, and their age ranged from 17 to 75 years. 10 patients had abdominal pain, 4 with melena or blood stool, and 2 with diarrhea. The longest course was 7 years, and the shortest 1 week. Before MR imaging, a nasoenteric catheter was inserted into the distal part of duodenum, and about 1000 ml of air was infused through the tube to distend the small bowel. 20 mg of IV anisodamine was given to reduce small-bowel peristalsis. All patients were imaged with fat-saturated Gd-DTPA enhanced coronal and axial T 1 -weighted spin-echo (SE) sequence and fast spoiled gradient echo (FSPGR) sequence. Comparison between the diagnosis of MRI and the results of surgery, pathology or clinic was performed to assess the sensitivity and specificity of MRI. Results: 5 cases were normal, 6 with Crohn disease, 2 with gastric intestinal stromal tumor (GIST), and 1 each of lymphoma, tuberculosis and irritable bowel syndrome. The lumen of normal small bowel in MR enteroclysis was no signal, the wall was outlined as middle signal by intraluminal air and surrounding air-distended bowel and was between 1-3 mm thick, and the diameter of the lumen was between 17-28 mm. Crohn disease showed segmental mural thickening, increased enhancement, luminal stricture, and even extraluminal inflammatory mass or fistula. Intestinal tuberculosis invaded the distal section of ileum, cecum, and the proximal ascending colon, the wall thickened and enhanced apparently, and cecum and proximal ascending colon shortened. GIST showed a mass that was iso-signal on T 1 WI, high signal on T 2 WI, and enhanced significantly after IV Gd-DTPA. 1 recurrent lymphoma of ileum showed mural thickening and increased

    To describe the sonographic (US) and clinical features of spontaneously reduced small bowel intussusception, and to discuss the management options for small bowel intussusception based on US findings with clinical correlation. During a five years of period, 34 small bowel intussusceptions were diagnosed on US in 32 infants and children. The clinical presentations and imaging findings of the patients were reviewed. The clinical presentations included abdominal pain or irritability (n = 25), vomiting (n 5), diarrhea (n = 3), bloody stool (n = 1), and abdominal distension (n = 1), in combination or alone. US showed multi-layered round masses of small (mean, 1.5 ± 0.3 cm) diameters and with thin (mean, 3.5 ± 1 mm) outer rims along the course of the small bowel. The mean length was 1.8 ± 0.5 cm and peristalsis was seen on the video records. There were no visible lead points. The vascular flow signal appeared on color Doppler images in all 21 patients examined. Spontaneous reduction was confirmed by combinations of US (n = 28), small bowel series (n = 6), CT scan (n = 3), and surgical exploration (n 2). All patients discharged with improved condition. Typical US findings of the transient small bowel intussusception included 1) small size without wall swelling, 2) short segment, 3) preserved wall motion, and 4) absence of the lead point. Conservative management with US monitoring rather than an immediate operation is recommended for those patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration

    We report an exceptional case of a 7 year-old patient with necrotic small bowel volvulus due to adult ascaris lumbricoides. At the admission, the child had intestinal obstruction evolving since two days with alteration of general state. Abdominal radiography without preparation showed small bowel air-fluid levels and tiger-stripe appearance evoking the diagnosis of acute intestinal obstruction associated with abdominal mass. After resuscitation, the surgical treatment consisted of laparotomy which showed necrotic volvulus of the terminal ileum containing adult ascaris lumbricoides. The patient underwent small bowel resection, approximately one meter of affected section was removed and then an ileostomy was performed. The evolution was favorable. The patient underwent ileorectal anastomosis four weeks later. After a 2 year follow-up period the child had no symptoms.

    Small bowel (SB) diverticulosis is a rare disorder that may entail serious complications, including SB diverticulitis. Both are often missed in imaging. Magnetic resonance enterography/enteroclysis (MRE) is increasingly used to assess SB disease; awareness of the appearance of SB diverticulitis is essential to ensure appropriate management. Our aim was to systematically describe imaging characteristics of SB diverticulosis and diverticulitis in MRE. This retrospective, HIPAA-compliant study identified 186 patients with suspected SB diverticulosis/diverticulitis in medical databases of two tertiary medical centres between 2005 and 2011. Patients with surgically confirmed diagnoses of SB diverticulosis/diverticulitis were included. Two observers analyzed MR images for the presence, location, number, and size of diverticula, wall thickness, and mural and extramural patterns of inflammation. Seven patients were recruited. MRI analysis showed multiple diverticula in all (100 %). Diverticular size ranged from 0.5 to 6 cm. Prevalence of diverticula was higher in the proximal than the distal SB (jejunum 86 %, ileum 57 %, distal ileum43%). Diverticulitis occurred in 3/7 patients (43 %) showing asymmetric bowel wall thickening and focal mesenteric inflammation. SB diverticulitis demonstrates characteristic MRE imaging features to distinguish this rare disorder from more common diseases. Asymmetric, focal mesenteric and mural inflammation and presence of multiple diverticula are keys to diagnosis. (orig.)

    Injury to the small bowel is one of the tragic complications of radiotherapy. We performed a retrospective analysis of patients operated upon for stenosis, perforation, fistulization, and chronic blood loss of the small bowel after radiotherapy for multiple malignant diseases. In the period 1970 to 1982 in the Department of General Surgery of the St. Radboud University Hospital, Nijmegen, and the Department of Surgical Oncology of the State University, Groningen, 27 patients were treated surgically. Twenty patients presented with obstruction. In 17 patients a side-to-side ileotransversostomy was performed; in three the injured bowel was resected. Of the five patients with fistulization, three underwent a bypass procedure; in two cases the affected bowel was resected. In one patient with perforation, a resection was performed, as in a patient with chronic blood loss. Two of the 20 patients (10 per cent) in whom the diseased bowel was bypassed died postoperatively. Of the seven patients whose affected bowel was resected four (57 per cent) died of intra-abdominal sepsis. Management of the patient with chronic radiation enteritis is discussed. We conclude, on the basis of our experience, that in patients with obstruction and fistulization, a bypass procedure of the affected bowel is a safe method of treatment. In case of resection, the anastomosis should be performed during a second operation.

    Seventy-seven patients, presenting with radiation small bowel injuries at the University of Texas M. D. Anderson Hospital and Tumor Institute at Houston between 1962 and 1978, were analyzed retrospectively. The patients were divided into two categories: bowel bypass without resection, and resection of irradiated bowel. Each group was then analyzed for its short- and long-term complications. Ileocolectomy with end-to-end anastomosis was the surgical procedure of choice in those people undergoing resection. There was no difference in short-term complications noted between the two groups. The long-term complications of fistula formation and continued small bowel necrosis could be prevented by resection, as a primary procedure. The surgical details of ileocolectomy with end-to-end anastomosis are presented, along with an analysis of the complications encountered in both groups.

    2017-07-01

    The options for the treatment of diarrhea and constipation are evolving as emerging therapies target small bowel receptors. The goal of this review is to discuss small bowel receptors involved in intestinal absorption, secretion, and motility. The review highlights therapies already approved or currently being studied for the modulation of these receptors. The articles cited in this review focus on the molecular level of pathways involved in diarrhea and constipation, and highlight the respective pharmacotherapies. The majority of the studies in the current literature investigate the effects of both the small and large intestine receptors on diarrhea and constipation. There are fewer studies that isolate the effects of these receptors solely on the small bowel, and focusing more on the receptors found distinctly in the small intestine may be an area of interest for future studies as this can inspire more targeted therapies.

    Full Text Available Background: Patency capsule was developed to avoid small bowel video capsule endoscopy retention, namely in patients with Crohn's disease. Aims: To evaluate the predictive factors of small bowel patency in Crohn's disease patients. Patients and methods: Retrospective analysis including 151 Crohn's disease patients submitted to patency capsule (Agile® Patency Capsule from 2011 to 2012. Patients that excreted the intact patency capsule were classified as having a patent small bowel (without patency capsule retention, other patients were considered to have negative patency of the small bowel (patency capsule retention. Results: Patients had a mean age of 41±14 years, 54% were female and 25% had been previously submitted to surgery. Stricturing disease was seen in 20% of cases and penetrating disease in 16% of cases. Left-sided colonic lesions and ileal strictures were observed at colonoscopy in 13% and 9% of patients, respectively. In our sample, 28% of patients had negative patency of the small bowel (patency capsule retention. In multivariate analysis, independent factors that were associated with negative patency of the small bowel in Crohn's disease patients were stricturing (OR 10.16, p < 0.001 and penetrating phenotypes (OR 11.73, p = 0.001, left-sided colonic lesions (OR 3.77, p = 0.038, ileal stricture (OR 9.76, p = 0.003; previous intestinal surgery was found to be protective (OR 0.16, p = 0.006. Conclusions: Stricturing or penetrating disease, ileal strictures, no previous surgery and left-sided colonic lesions were the factors associated with negative small bowel patency in Crohn's disease patients.

    Full Text Available Jejunal diverticulosis is rare and often goes unnoticed until complications occur. The diverticula are true, acquired diverticula and often asymptomatic. Jejunal diverticulosis can be associated with diverticulosis of the duodenum, ileum, and colon. Here we describe a patient with known severe diverticular disease of the large bowel, who presented acutely with abdominal pain and signs of generalised peritonitis. Laparotomy showed ruptured jejunal diverticulosis with a single band over the terminal ileum, causing small bowel obstruction. Spontaneous perforation of a jejunal diverticulum is rare and is usually an intraoperative finding. One should exclude a precipitating cause, such as coexisting distal obstruction, stricture, or a foreign body.

    2016-03-01

    Because of the difficulty often encountered in deciding whether a patient's symptoms originate in the upper or lower gastrointestinal tract, gastrointestinal transit scintigraphy is a uniquely suited noninvasive, quantitative, and physiologic method of determining whether there is a motility disorder affecting the stomach, small bowel, or colon. Small-bowel and colon transit studies can be performed alone or together with gastric emptying studies after oral administration of an appropriately radiolabeled meal. It is hoped that newly published standards for performing these studies and the anticipated arrival of new Current Procedural Terminology codes in the United States for small-bowel and colon transit studies will increase their availability and use. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

  11. Merkel cell carcinoma metastatic to the small bowel mesentery

    2011-03-01

    Full Text Available Merkel cell carcinoma (MCC is an uncommon cutaneous malignant tumor that presents as a rapidly growing skin nodule on sun-exposed areas of the body. MCC is aggressive with regional nodal and distant metastases to the skin, lung, and bones. There have been no reports of metastatic MCC to the mesentery and 6 reports describing metastasis to the small intestine. We present a case of metastatic MCC to the mesentery with infiltration to the small bowel, 8 years after original tumor resection. This is the 5th metastasis and it encased the small bowel resulting in a hair-pin loop contributing to the unusual clinical presentation. Although MCC metastatic to the bowel is uncommon, it is not rare. It is important to recognize the unusual manifestations of this disease as they are becoming more common in the future. Routine radiologic surveillance and thorough review of systems are important to patient follow-up.

  13. Small bowel obstruction: the role of computed tomography in its diagnosis and management with reference to other imaging modalities

    International Nuclear Information System (INIS)

    Burkill, G.; Bell, J.; Healy, J.

    2001-01-01

    Small bowel obstruction is a leading cause of acute surgical admissions for abdominal pain. There is an increasing tendency for initial conservative management rather than immediate operative intervention, as a proportion of cases will resolve spontaneously. This has resulted in a growing reliance on radiological investigations to reassure the surgeon that medical therapy can be safely instituted. The onus therefore rests with radiologists to guide their surgical colleagues by correctly interpreting the plain abdominal radiograph and suggesting appropriate further investigation if warranted. Recently, computed tomography (CT) has been proposed as the test of choice to define the level and cause of acute small bowel obstruction and to identify complications such as ischaemia and perforation which will prompt surgical intervention. This review will discuss the utility of early CT in the diagnosis of acute small bowel obstruction and outline its impact on patient management. (orig.)

    Individuals with diverticulosis frequently also have irritable bowel syndrome (IBS), but there are no longitudinal data to associate acute diverticulitis with subsequent IBS, functional bowel disorders, or related emotional distress. In patients with postinfectious IBS, gastrointestinal disorders cause long-term symptoms, so we investigated whether diverticulitis might lead to IBS. We compared the incidence of IBS and functional bowel and related affective disorders among patients with diverticulitis. We performed a retrospective study of patients followed up for an average of 6.3 years at a Veteran's Administration medical center. Patients with diverticulitis were identified based on International Classification of Diseases, 9th revision codes, selected for the analysis based on chart review (cases, n = 1102), and matched with patients without diverticulosis (controls, n = 1102). We excluded patients with prior IBS, functional bowel, or mood disorders. We then identified patients who were diagnosed with IBS or functional bowel disorders after the diverticulitis attack, and controls who developed these disorders during the study period. We also collected information on mood disorders, analyzed survival times, and calculated adjusted hazard ratios. Cases were 4.7-fold more likely to be diagnosed later with IBS (95% confidence interval [CI], 1.6-14.0; P = .006), 2.4-fold more likely to be diagnosed later with a functional bowel disorder (95% CI, 1.6-3.6; P mood disorder (CI, 1.4-3.5; P IBS and functional bowel disorders. We propose calling this disorder postdiverticulitis IBS. Diverticulitis appears to predispose patients to long-term gastrointestinal and emotional symptoms after resolution of inflammation; in this way, postdiverticulitis IBS is similar to postinfectious IBS.

  15. Development of a new method for small bowel transit study

    2006-01-01

    Currently, most studies combine the small bowel transit examination with gastric emptying time examination. There are significant drawbacks to this method. The radiotracer does not enter the small intestine in a bolus and the starting time for transit in the duodenum is difficult to define. This makes the result unreliable. In this study, we used a commercial enteric capsule containing radioactive charcoal to solve these problems. Activated charcoal powder was mixed with Tc-99m pertechnetate and loaded to the enteric capsule which can resist gastric acid and dissolve only in the small intestine, in-vitro stability experiment was performed by immersing these capsules in a colorless phosphate buffer of variable pH which mimicked the condition in stomach and small intestine. In addition, ten healthy Chinese volunteers were included for in-vivo experiment. Anterior and posterior views of abdomen were obtained at regular 30-minute intervals until the eighth hour after administration of the radioactive enteric capsule. Small bowel transit time was calculated. The enteric capsule remained intact for at least 480 minutes in the solution mimicking gastric content (pH=3.0) and disrupted at a mean duration of 227.2 minutes at a pH of 6.8 and at a mean duration of 212.4 minutes at a pH of 7.4 in the solution mimicking pancreaticobiliary secretions. In nine of ten volunteers, the small bowel transit time was between 30 to 270 minutes with a mean transit time of 140 min. In one volunteer, we failed to detect the exact time of small bowel transit because the capsule remained in the stomach throughout the study for up to 8 hours. We consider activated charcoal labeled with Tc-99m pertechnetate using an enteric capsule as the carrier to be a potential radioactive marker for small bowel transit study. (author)

    1995-05-01

    Transvaginal small-bowel evisceration is rare. Only 47 case reports appear in the literature in English. Review of this literature shows that vaginal evisceration occurs mainly in women who are older, multiparous, and have undergone vaginal surgery. The immediate cause of evisceration is either sudden, increased intraabdominal pressure, trauma, or a spontaneous event. The small bowel and omentum are most commonly involved. Surgical repair is performed vaginally, abdominally, or by both methods. We present a case of transvaginal small bowel evisceration caused by inadvertent self-induced trauma, a heretofore unreported cause of this complication, in a 79-year-old woman with known weakness of her pelvic structural support. She experienced sudden evisceration of small bowel following manual decompression of her cystocele during voiding. We used a combined abdominal and vaginal approach to examine the small and large intestines and mesentery for trauma, attach the vaginal vault to the shortened uterosacral ligament, obliterate the cul-de-sac using the Moschowitz procedure, and repair the defect in the levator plate. To limit risk, patients should be evaluated for predisposing conditions. We recommend a combined abdominal and vaginal surgical approach to adequately evaluate the involved tissues and to effect repair.

    Carcinoid is a slowly-growing tumor from the group of neuroendocrine or APUD tumors. Characteristic of these tumors is the production of biogene amins & polypeptide hormones. 90% of all carcinoids are located in the GI system. A female patient, 68 years old, comes for a visit with signs of diffuse abdominal pain, diarrhea, irregular bowel movements, weakness, dyspnea and pretibial edemas. The gastroenterologist gives her only symptomatic therapy at first, and starts the examinations after her hospitalization (initial dg: Enterocolitis). One month later she visits again with the same complains. CT scan result shows steatosis hepatica and lots of liquids in the small bowel and colon. She underwent operation--resection of 20 cm of the small bowel with tumor masses and part-time ileostoma. The biopsy of the resected segment of the bowel shows multiple carcinoids. Our patient had no flushing of the skin and therefore couldn't be suspected clinically for this diagnosis. The intestinal carcinoid does not usually produce the carcionid syndrome unless hepatic metastases have occurred. The infiltration of the mesentery provokes an intense fibrotic reaction resulting in kinking of the bowel segments, which causes intestinal obstruction as it happened in this patient. As long as in our clinic we don't have this technique, it is much harder to make an early diagnosis. Fortunately our patient was diagnosed before liver metastases occurred, and therefore her treatment was successful.

    Endometriosis is a gynaecological condition which produce symptoms such as pelvic pain, abnormal menstruation and infertility. Intestinal endometriosis can occur however endometriosis causing acute large bowel obstruction is extremely rare. We present a 37-year-old lady with acute large bowel obstruction caused by endometriosis. Despite initial endoscopic decompression being unsuccessful due to severe mucosal stenosis, she underwent emergency laparoscopic wedge resection and decompression successfully. Diagnosing intestinal endometriosis is difficult. While different modalities of investigation help, definitive diagnosis is achieved via laparoscopy. Treatment of obstruction is decompression followed by surgical resection. Diagnosing intestinal endometriosis with or without obstruction is challenging. Correct diagnosis is needed for definitive management. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Objective: Celiac disease (CD) is a common, lifelong disease with small bowel malabsorption based on genetically conditioned gluten intolerance. The clinical manifestation could be very heterogeneous. The proof of celiac disease is now based mainly on clinical and laboratory (antibodies and enterobiopsy) signs, which are in some cases problematic and inconvenient. Materials and methods: In our study we have examined 250 patients with suspection or with proven celiac disease and we evaluated specific ultrasound small bowel changes in this group. In the next step, we chose 59 patients with laboratory proved celiac disease and we statistically compared ultrasound, other laboratory and clinical findings in different forms and stages of the disease. Results: Specific small bowel pathologies in patients with celiac disease (like changes of intestinal villi in different parts of small bowel, abnormal peristalsis and mesenterial lymphadenopathy) can be well visualized by ultrasound and in combination with clinical and laboratory signs ultrasound examination could have an important role in screening, determination of diagnosis and monitoring of patients with different forms of celiac disease.

    2007-10-01

    Full Text Available Abstract Background Resection of peritoneal metastases has been shown to improve survival in patients with abdominal metastatic disease from abdominal or extra abdominal malignancy. This study evaluates the benefit of peritoneal metastatic resection in patients with malignant small bowel obstruction and a past history of treated cancer. Patients and methods Patients undergoing laparotomy for resection of peritoneal metastases from recurrence of previous cancer between 1992–2003 were reviewed retrospectively. Data were collected about type of primary cancer, interval to recurrence, extent of the disease and completeness of resection, morbidity and mortality and long-term survival. Results Between 1992 and 2003 there were 79 patients (median age 62, range 19–91 who had laparotomy for small bowel obstruction due to recurrent cancer. The primary cancer was colorectal (31, gynaecologic cancer (19, melanoma (16 and others (13. Overall, the rate of complications was 35% and mortality was 10%. Median survival was 5 months; patients with history of colorectal cancer had better survival than other cancer (median survival 7 months vs. 4 months; p = 0.02. Multivariate analysis showed that the extent of recurrent disease was the only factor that affected overall survival. Conclusion Laparotomy for small bowel obstruction is a worthwhile option for patients with malignant small bowel obstruction. Although it is associated with significant morbidity and mortality it offers a reasonable survival benefit in particular for patients with completely resectable disease.

Tertiary referral centre in Rome, Italy. A 58 year-old patient with a FIGO Stage IB G2 N0 endometrial cancer was found to have a vaginal cuff recurrence and an isolated distant metastasis to the small bowel 13 months after primary treatment. In this video we show a fully laparoscopic management mainly focusing on small bowel resection with intracorporeal anastomosis. A laparoscopic partial colpectomy was also performed. Our institutional review board approved this study. Operative time was 180 minutes. Intraoperative blood loss was less than 100 mL. The operation was performed successfully with no intraoperative complications. Pathologic findings showed recurrent disease in the vaginal cuff and in the resected small bowel segment with free resection margins in both specimens and 3 mesenteric local nodes negative for metastasis. The patient was discharged on day 3 and 26 days later started adjuvant chemotherapy. After a 16-month follow-up period, the patient is still disease free and in good general conditions. This case shows a successful laparoscopic management of recurrent endometrial cancer equiring complex surgical procedures. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

    Full Text Available Introduction. A patent urachus is a rare congenital or acquired pathology, which can lead to complications later in life. We describe a case of urachal cystitis as the etiology of small bowel obstruction in an adult without prior intra-abdominal surgery. Case Report. A 64-year-old male presented to the acute care surgery team with a 5-day history of right lower quadrant abdominal pain, distention, nausea, and vomiting. He had a two-month history of urinary retention and his past medical history was significant for benign prostate hyperplasia. On exam, he had evidence of small bowel obstruction. Computed tomography revealed high-grade small bowel obstruction secondary to presumed ruptured appendicitis. In the operating room, an infected urachal cyst was identified with adhesions to the proximal ileum. After lysis of adhesions and resection of the cyst, the patient was subsequently discharged without further issues. Conclusion. Although rare, urachal pathology should be considered in the differential diagnosis when evaluating a patient with small bowel obstruction without prior intraabdominal surgery, hernia, or malignancy.

  12. PROSPECTIVE EVALUATION OF AETIOPATHOGENESIS AND MANAGEMENT OF SMALL BOWEL OBSTRUCTION IN ADULTS

    2016-05-01

    Full Text Available INTRODUCTION Small bowel obstruction is a common surgical emergency. The small bowel is involved in about 80 percent of cases of mechanical intestinal obstruction. Mode of presentation is same in all but underlying cause varies in each age group. The dictum of never let the sun set or rise in small bowel obstruction has made early surgical intervention for small intestinal obstruction. This in turn has reduced the incidence of strangulation of bowel, which was major cause of mortality in already ill patient. Success in treatment of patient with acute intestinal obstruction depends largely upon early diagnosis, skilful management and appreciation of importance of treating the pathological effects of obstruction just as much as the cause itself. METHODS This is a prospective study which was done on patient with small bowel obstruction between September 2013 to August 2015 in M.K.C.G. Medical College and Hospital, Brahmapur, Odisha. All the patients were subjected to questionnaires and clinical examination, routine and special investigations like abdominal X-ray in erect posture, treatment modality based on laparotomy findings and postoperative observation for any complications. RESULT In this study, it is observed that bands and adhesions followed by hernia were the commonest causes of small bowel obstruction in adults. Pain abdomen, vomiting, distention, constipation, tenderness over abdomen and increased bowel sounds are seen in majority of cases. Maximum incidence occurred in 3 rd decade of life with M:F ratio of 1.73:1. Plain X-ray erect abdomen was almost conclusive in all cases. Resection and anastomosis followed by adhesiolysis were the two procedures which were commonly performed. Morbidity increased in old age patients and those whose presentation was late. CONCLUSION Small bowel obstruction remains a frequently encountered problem in abdominal surgery. The risk of strangulation with adhesive and neoplastic SBO is relatively low as

On exploration she was found to have an obstructed obturator hernia, which is a rare pelvic hernia with an incidence of 0.07-1.4% of all intra-abdominal hernias. Diagnosis is often delayed until laparotomy for bowel obstruction. Strangulation is frequent and mortality remains high (25%. Early diagnosis and surgical treatment contributes greatly to reduce the mortality and morbidity rates. A variety of techniques have been described, however surgical repair has not been standardized. It is an important diagnosis to be considered in elderly patients with intestinal obstruction.

    A series of 21 subjects (2 males and 19 females) affected with systemic sclerosis, was examined by small bowel (oral and intubation methods) and colon enema. The underlying process responsible for abnormalities in the small bowel and colon in systemic sclerosis is a variable and pacthy destruction of the muscularis propria, that produces the structural and functional changes detected on X-ray: Pathologic condition is the same affecting the esophagus. The scout film of the abdomen often reveals colonic distension and fecal impaction, so that it may be quite difficult to prepare adequately the patients for a barium enema. Peristalsis may be virtually absent in short segments, and transit time may be several time longer than that in normal patients. For these reasons, intestinal pseudo-obstruction may appear in systemic sclerosis. The observed radiographic changes are: 1) in the small bowel: a) dilatation of the gut, especially in its proximal portions (duodenum and jejunum), in which the valvulae conniventes are straightened, normal or thinned; b) presence of diverticula, 2-4 cm in diameter, with hemispherical shape without the neck-like opening into the bowel lumen; 2) in the colon, the characteristic finding is an increase in size of individual haustra, forming sacculations or pseudo-diverticula, usually on the antemesenteric border of the transverse colon, better demonstrated on post-evacuation film. Moreover, loss of colonic haustration is also observed associated to colonic elongation and dilatation

    2010-01-01

    Background Diarrhea is common in HIV/AIDS patients, caused by both classic enteric pathogens and different opportunistic agents. Infection with these different pathogens may lead to similar radiological findings, thus causing diagnostic confusion. Case presentation A 30-yr-old female with AIDS presented with chronic diarrhea of 4 months duration. She had diffuse small bowel thickening present on CT scan of her abdomen, with stool examination showing no parasites. She was erroneously diagnosed as abdominal tuberculosis and given antituberculosis drugs with which she showed no improvement. Repeat stool examination later at a specialized laboratory revealed Cryptosporidium parvum infection. The patient was given an extended course of nitazoxanide treatment, as her stool examination was positive for Cryptosporidium parvum even after 2 weeks of drug consumption. Parasite clearance was documented after 10 weeks of treatment. Interestingly, the bowel thickening reversed with parasitological clearance. Conclusions Cryptosporidium parvum may lead to small bowel thickening in AIDS patients. This small bowel thickening may reverse following parasitological clearance. PMID:21029408

    Full Text Available Bezoars represent the fifth most frequent cause of acute small bowel obstruction. Phytobezoar is the most common type of bezoar. It is a concretion of undigestible fibers derived from ingested vegetables and fruits. We report a case of a woman with a 1-year history of recurrent epigastric and periumbilical abdominal pain with intermittent vomiting caused by phytobezoar of the terminal ileum. After careful investigation of the case and review of literature, we identified the factor involved in bezoar formation as radiation-induced ileal stenosis due to previous treatment for a pelvic tumour. This report provides evidence to consider phytobezoar as a possible cause of small bowel obstruction in patients previously treated with abdominal radiotherapy.

    To recognize and document the small bowel reactions following major abdominal surgery is an important key for a correct diagnosis. Usually, plain abdominal radiography is the initial imaging examination requested in the immediate postoperative period, whereas gastrointestinal contrast studies are used to look for specific complications. In some countries, especially in Europe, sonography is widely employed to evaluate any acute affection of the abdomen. CT is commonly used to assess postoperative abdominal complications; in our institution also CT enteroclysis is often performed, to provide additional important informations. Radiologist should be able to diagnose less common types of obstruction, such as afferent loop, closed loop, strangulating obstruction as well as internal hernia. This knowledge may assume a critical importance for surgeons to decide on therapy. In this article, we focus our attention on the imaging (particularly CT) in small bowel complications following abdominal surgery.

    BACKGROUND: Postoperative adhesions are a common cause of small-bowel obstruction, and up to 53% of patients operated on for adhesive small-bowel obstruction (ASBO) experience recurrence. The primary aim of this study was to identify predictors for recurrence of ASBO. METHODS: We reviewed medical......: In total, 478 patients were included in the study. Of these, 58 (12.1%) patients experienced recurrence of ASBO during median 2.2 years follow-up. Female gender (hazard ratio [HR] 2.00, P = 0.023), multiple/matted adhesions (HR 1.72, P = 0.046), and fascial dehiscence (HR 3.26, P = 0.009) were associated...... with an increased risk were female gender, multiple/matted adhesions, and fascial dehiscence....

    2009-12-01

    The use of Naso-Jejunal (NJ) feeding is limited by difficulty in feeding tube placement. Patients have traditionally required transfer to Endoscopy or Radiology for insertion of small bowel feeding tubes, with clear resource implications. We hypothesised that the adoption of a simple bedside procedure would be effective and reduce cost. Clinical nutrition and nurse specialist personnel were trained in the 10\\/10\\/10 method of blind bedside NJ insertion.

    Gastrointestinal fistulae associated with open abdomen are serious complications following trauma or other major abdominal surgery. Management is extremely difficult and the mortality is still high in spite of modern medical advances. Patients who survive initial physiological and metabolic derangements require operative closure of the fistula, which is technically demanding and poorly described in the literature.

    2012-09-01

    Full Text Available Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki. We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery.

    2002-01-01

    The radiological characteristic features of Crohn's disease located in the small bowel are made up of three main syndromes. Prestenotic - involving the small bowel loops proximally to the pathological process. Strong peristalsis with retroperistalsis, along with fluid and mucus collection, intestinal lumen widening up to 3 - 6 am diameter and formation of gas fluid levels are observed. Stenotic - presenting irregularly narrowed section with rigid walls, uneven rough polymorphic contours with gradual transition to the other part of the intestine. Ulcero-polypoid syndrome mirroring changes in the small-bowel mucosa - longitudinal, circular and oval contrast material depots are seen - ulcer destructions. When fistulas are formed, long spicular added shadows appear along the contour. Not infrequently such fistulas communicate with other parts of gastrointestinal tract; large polymorphic clear zones are also visualized - pseudo polyps. The images observed upon fractionated contrast material passage are supplemented be computerized tomography and percutaneous abdominal sonography - the so called cockade symptom associated with thickening of the intestinal wall, mesenteric hypervascularization and the like. Enteroclysis which are method of choice is not used owing to technical reasons. (authors)

    BACKGROUND & AIMS: Inflammatory bowel disease (IBD) may increase risk of small bowel cancer (SBC). However, little is known of the characteristics and features of IBD-SBC, due to a low number of cases worldwide. We performed a population-based study of IBD and SBC to calculate risk and increase our...... understanding of clinical characteristics and histopathological and molecular features. METHODS: The study population consisted of all individuals aged 16 years or older living in Denmark during 1978-2010. Through linkage between national registers and subsequent scrutiny of medical records and pathology...... descriptions, we identified 40 cases of IBD-SBC. Risk was calculated by standardized incidence ratio (SIR) (observed/expected); patient characteristics were derived from medical files, and surgery specimens were obtained from hospitals nationwide for histopathological and molecular analyses.

    2001-08-01

    Small intestinal submucosa (SIS) is an extracellular matrix used in tissue engineering studies to create de novo abdominal wall, urinary bladder, tendons, blood vessels, and dura mater. The purpose of this study is to evaluate the feasibility of using SIS as a scaffold for small bowel regeneration in an in situ xenograft model. Twenty-three dogs had a partial defect created on the small bowel wall which was repaired with a SIS patch. Four dogs underwent small bowel resection with placement of an interposed tube of SIS. The animals were followed 2 weeks to 1 year. Three of the 23 dogs with SIS placed as a patch died shortly after surgery due to leakage from the site. The other 20 dogs survived up to time of elective necropsy with no evidence of intestinal dysfunction. At necropsy, the bowel circumference in the patched area had no stenosis. Histological evaluation showed the presence of a mucosal epithelial layer, varying amount of smooth muscle, sheets of collagen, and a serosal covering. Architecturally, the layers were not well organized in the submucosal region. An abundance of inflammatory cells was present in the early postoperative period but receded with time. All 4 dogs with a tubular segment of SIS interposed had significant problems. One had partial obstruction at 1 month, and 3 died in the early postoperative period due to leakage. This preliminary study suggests that SIS patches can be used for small bowel regeneration. Tubular segmental replacement is not feasible at this time. Copyright 2001 Academic Press.

    Systemically administered misoprostol, a PGE analog, has been shown to be an intestinal radioprotector. The purpose of this study was to determine if administration of misoprostol into the intestinal lumen can also reduce the severity of acute radiation enteritis. The rat small bowel was operatively exteriorized and segmented by means of suture ties. The remainder of the intestine and the rat were shielded in a lead box. Misoprostol was introduced into the lumen in various doses. After 30 min exposure to misoprostol, the isolated, exteriorized, segmented bowel was subjected to 11 Gy X irradiation. Five days later the animals were sacrificed and the intestines harvested for evaluation. Surviving crypt numbers per circumference and mucosal height were the criteria used for quantification of damage. Mucosa exposed to misoprostol at the time of radiation delivery showed significantly increased crypt numbers and mucosal height compared to adjacent saline-filled intestine. 24 refs., 2 figs., 2 tabs.

    AIMS: The pneumocolon technique in small bowel meal examination is used to obtain double-contrast views of the distal ileum. The purpose of this study was to determine the proportion of cases in which an overhead pneumocolon radiograph demonstrated clinically relevant findings in the colon. METHODS: The overhead pneumocolon radiographs in 151 patients who underwent small bowel meals were evaluated retrospectively. A chart review was performed on those patients with positive colonic findings to determine if the suspected abnormalities affected patient management. RESULTS: Colonic abnormalities were identified in 34 of the 151 patients. One patient had a previously undiagnosed ascending colonic cancer; 17 had evidence of acute or chronic colitis; 13 had diverticulosis; one had a caecal polyp; one had an ileosigmoid fistula; one had a filling defect in the ascending colon. In 25 cases the colonic abnormality was visible only on the pneumocolon radiograph and not on the preceding single-contrast images. Management was altered by the colonic findings in seven cases. False-positive findings occurred in two cases. CONCLUSIONS: A routine overhead radiograph following use of the pneumocolon technique is a useful adjunct to small bowel meal examination as it can yield unsuspected and clinically significant colonic findings.

    O'Daly, Brendan J

    2009-06-01

    BACKGROUND: Predicting the clinical course in adhesional small bowel obstruction is difficult. There are no validated clinical or radiologic features that allow early identification of patients likely to require surgical intervention. METHODS: We conducted a retrospective review of 100 patients consecutively admitted to a tertiary level teaching hospital over a 3-year period (2002-2004) who had acute adhesional small bowel obstruction and underwent computed tomography (CT). The primary outcomes that we assessed were conservative management or the need for surgical intervention. We investigated time to physiologic gastrointestinal function recovery as a secondary outcome. We examined independent predictors of surgical intervention in a bivariate analysis using a stepwise logistic regression analysis. RESULTS: Of the 100 patients investigated, we excluded 12. Of the 88 remaining patients, 58 (66%) were managed conservatively and 30 (34%) underwent surgery. Peritoneal fluid detected on a CT scan (n = 37) was associated more frequently with surgery than conservative management (46% v. 29%, p = 0.046, chi(2)). Logistical regression identified peritoneal fluid detected on a CT scan as an independent predictor of surgical intervention (odds ratio 3.0, 95% confidence interval 1.15-7.84). CONCLUSION: The presence of peritoneal fluid on a CT scan in patients with adhesional small bowel obstruction is an independent predictor of surgical intervention and should alert the clinician that the patient is 3 times more likely to require surgery.

    MRI of the small bowel is a new method for the assessment of inflammatory bowel diseases. However, inflammatory bowel disease can affect both the small and large bowel. Therefore, our goal was to assess the feasibility of displaying the small bowel and colon simultaneously by MR imaging. Eighteen patients with inflammatory bowel disease were studied. For small bowel distension, patients ingested a solution containing mannitol and locust bean gum. Furthermore, the colon was rectally filled with water. MR examinations were performed on a 1.5-T system. Before and after intravenous gadolinium administration, a T1w data set was collected. All patients underwent conventional colonoscopy as a standard of reference. The oral ingestion and the rectal application of water allowed an assessment of the small bowel and colon in all patients. By means of MRI (endoscopy), 19 (13) inflamed bowel segments in the colon and terminal ileum were detected. Furthermore, eight additional inflammatory lesions in the jejunum and proximal ileum that had not been endoscopically accessible were found by MRI. The simultaneous display of the small and large bowel by MRI is feasible. Major advantages of the proposed MR concept are related to its non-invasive character as well as to the potential to visualize parts of the small bowel that cannot be reached by endoscopy. (orig.)

    The shortage of organs in the last 20 years is stimulating the development of new strategies to expand the pool of donors. The harvesting of a graft from non-heart-beating donors (NHBDs) has been successfully proposed for kidney and liver transplantation. To our knowledge, no studies are available for small bowel transplantation using NHBDs. In an experimental setting of small bowel transplantation, we studied the feasibility of using intestinal grafts retrieved from NHBDs. Twenty five Large White piglets underwent total orthotopic small bowel transplantation and were randomly divided as follow: NHBD group (n = 15) received grafts from NHBDs; heart-beating donor (HBD) group (n = 10) received grafts from HBDs. The NHBD pigs were sacrificed inducing the cardiac arrest by a lethal potassium injection. After 20 minutes (no touch period = warm ischemia), they underwent cardiac massage, laparotomy, and aorta cannulation for flushing and cooling the abdominal organs. In HBDs, the cardiac arrest was induced at the time of organ cold perfusion. In both groups, immunosuppression was based on tacrolimus oral monotherapy. The animals were observed for 30 days. The graft absorptive function was studied at day 30 using the D-xylose absorption test. Histological investigation included HE (Hematoxilin and Eosin) microscopical analysis and immunohistological staining. Animals in the NHBD group died due to infection (n = 3), acute cellular rejection (n = 2), technical complications (n = 2), and intestinal failure (n = 8). In the HBD group, all animals but two were alive at the end of the study. The D-xylose absorption was significantly lower among the NHBD compared with the HBD group (P intestinal mucosa is sensitive to ischemic injury. When the intestinal graft is harvested from NHBDs, the infectious-related mortality was higher and the absorptive function lower. Histological examination confirmed a higher grade of ischemic injury in the NHBD grafts that correlated with the

    1980-01-01

    In order to predict which patients have a high risk for radiation-related small-bowel damage, the concept of the dose-response curve was applied to the predisposing factors (number of previous laparotomies, extent of surgery, thin physique, hypertension, age, cancer stage, number of treatment days, fractionation, and weight change during radiotherapy) present in 92 patients receiving identical radiation doses and volumes This analysis allows an estimate of the probability of complication to be assigned to individual patients. The utility and limitations of the dose-response concept are discussed

    The standard technique for percutaneous gastrostomy requires insufflation of air into the stomach via a nasogastric tube before percutaneous gastric puncture. We present a previously undescribed complication in which the insertion of a percutaneous gastrostomy tube resulted in the distention of a previously undiagnosed giant small bowel diverticulum. This led to discomfort for the patient, further radiologic investigation and a delay in discharge. Symptoms resolved with conservative management. We suggest a strategy for avoiding this complication, as well as for reducing the incidence of post-procedure ileus. (author)

    Cystic lymphangioma is an uncommon mesenteric tumor which is usually reported in children. We describe a case of a 12-years old girl who was admitted in our hospital with abdominal distension and pain. Physical examination showed an abdomino-pelvic mass. Preoperative studies including abdominal ultrasonography and computed tomography failed to determine the cause of the pain. Laparotomy found a giant cystic tumor of the small bowel mesentery. Histological studies confirm the diagnosis of cystic lymphangioma. Based on this case, a review of the literature is suggested. PMID:22145071

    Anisakiasis, a parasitic infection by larvae of the nematode Anisakis found in raw or undercooked saltwater fish, mostly involves stomach but rarely small intestine. We report a rare case of a 61-year-old man who presented with abdominal pain and developed small bowel obstruction caused by intestinal anisakiasis. Abdominal computed tomography revealed segmental edema of the intestinal wall with proximal dilatation. The patient underwent urgent laparotomy because strangulated small bowel obstruction was suspected. A localized portion of the intestine around jejunoileal junction was found to be erythematous, edematous, and hardened, which was resected. The resected specimen showed a linear whitish worm, Anisakis simplex, penetrating into the intestinal mucosa. It is often clinically challenging to consider intestinal anisakiasis in the differential diagnosis because of its nonspecific abdominal symptoms and findings. Although gastrointestinal anisakiasis is still rare in the United States, the incidence is expected to rise given the growing popularity of Japanese cuisine such as sushi or sashimi. Anisakiasis should be considered as one of the differential diagnoses in patients with nonspecific abdominal symptoms after consumption of raw or undercooked fish. Copyright © 2013 Elsevier Inc.

    Small bowel obstruction is a clinical condition commonly caused by postoperative adhesion, volvulus, intussusceptions, and hernia. Small bowel obstruction due to bezoars is clinically uncommon, accounting for approximately 2-4% of all obstructions. Computed tomography (CT) is a useful method in diagnosing the cause of small bowel obstruction. However, small bowel obstruction caused by bezoars may not be detected by an abdominal CT examination. Herein, we report a rare case of small bowel obstruction by Aloe vera bezoars, which were undetected by an abdominal CT. Phytobezoars should be included in the differential diagnosis of small bowel obstruction in patients with predisposing factors, such as excessive consumption of high-fiber food and diabetes.

    Full Text Available The incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. It occurs mostly in patients in the 6th decade of their life. Of all the small bowel diverticuli, jejunal diverticulum is the most common type. This rare entity is usually asymptomatic. However, they may cause chronic non-specific symptoms for a long period of time like dyspepsia, chronic postprandial pain, nausea, vomiting, borborgymi, alternating diarrhoea and constipation, weight loss, anaemia, steatorrhea or rarely lead to complications like haemorrhage, obstruction, perforation. Obstruction can be due to enterolith, adhesions, intussusception, and volvulus. The condition is difficult to diagnose because patients are generally presented with symptoms that mimic other diseases. It is important for clinicians to have awareness of this entity. Here, we present a case of multiple jejunal diverticuli with a history of repeated attacks of diverticulitis over past 20 years, which were misdiagnosed and now presented with intestinal obstruction due to volvulus of the involved segment along with mesentery around its axis. Resection of the diverticuli segment of jejunum was done with end-to-end jejuno-jejunal anastomosis. The patient is asymptomatic since 10 months of follow-up.

    Full Text Available Abstract Introduction Phytobezoars are concretions of poorly digested fruit and vegetable fibers found in the alimentary tract. Previous gastric resection, gastrojejunostomy, or pyloroplasty predispose people to bezoar formation. Small-bowel bezoars normally come from the stomach, and primary small-bowel bezoars are very rare. They are seen only in patients with underlying small-bowel diseases such as diverticula, strictures, or tumors. Primary small-bowel bezoars almost always present as intestinal obstructions, although it is a very rare cause, being responsible for less than 3% of all small-bowel obstructions in one series. Jejunal diverticula are rare, with an incidence of less than 0.5%. They are usually asymptomatic pseudodiverticula of pulsion type, and complications are reported in 10% to 30% of patients. A phytobezoar in a jejunal diverticulum is an extremely rare presentation. Case presentation A 78-year-old Pakistani man presented to our clinic with small-bowel obstruction. Upon exploration, we found a primary small-bowel bezoar originating in a jejunal diverticulum and causing jejunal obstruction. Resection and anastomosis of the jejunal segment harboring the diverticulum was performed, and our patient had an uneventful recovery. Conclusion Primary small-bowel bezoars are very rare but must be kept in mind as a possible cause of small-bowel obstruction.

    Full Text Available Microscopic polyangiitis is an uncommon systemic vasculitis of varying severity that is associated with myeloperoxidase (MPO and perinuclear antineutrophil cytoplasmic (p-ANCA antibodies. The most commonly affected organs are the lungs and kidneys. We report on a very unusual case of microscopic polyangiitis presenting with severe mesenteric ischemia in addition to diffuse alveolar hemorrhage and acute renal failure. The patient was initially diagnosed with acute pancreatitis at an outside facility given his severe abdominal pain and elevated pancreatic enzymes. Further investigations after transfer to our facility determined that the patient was actually suffering from a severe exacerbation of previously diagnosed microscopic polyangiitis. He quickly developed diffuse alveolar hemorrhage (DAH necessitating intubation and acute kidney injury (AKI requiring dialysis. He subsequently developed mesenteric ischemia and bowel necrosis resulting in emergent laparotomy and extensive small bowel resection. Physicians need to be aware that microscopic polyangiitis can very rarely present with severe involvement of the abdominal viscera and mesenteric vessels. Severe disease necessitates the use of high dose IV steroids, rituximab or cyclophosphamide, and plasma exchange (PLEX.

    Full Text Available Bezoars are concretions of foreign materials that impair gastrointestinal motility or cause intestinal obstruction in the stomach, small intestine or bowel of humans or animals. There are many types of them such as phyto, lacto and trichobezoars. Although bezoars are not rare, multiple giant bezoars which totally fill the stomach lumen and have extension to the small intestine (Rapunzel syndrome are very rare. This is a case report of a young girl who had a history of trichophagia and presented with partial gastric and intestinal obstructive signs. The patient was healthy, and her physical exam was almost normal and the only positive thing in her past medical history was trichophagia from several years ago. She had a big trapped bobble in her stomach and several air-fluid levels in abdominal radiograph and was investigated with endoscopy which confirmed the diagnosis of a huge gastric trichobezoar.

    There is no consensus concerning small bowel preparation before capsule endoscopy (CE). This study evaluated the effects of 4 regimens on small bowel cleansing and diagnostic yield. Patients were randomly divided into 4 groups. Group A consumed a clear liquid diet after lunch on the day before CE, followed by overnight fasting. Group B took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In group C, the same regimen was taken at 20:00 hours on the day before and at 05:00 hours on the day of CE. In group D, in addition to the group C regimen, 20 mL oral simethicone was taken 30 minutes before CE. Two hundred patients were prospectively enrolled, and 7 were excluded from the final analysis because of incomplete small bowel transit. No significant difference was noted among the 4 groups for small bowel transit time. Bowel preparation in group D was significantly better than for the other regimens for overall cleansing of the proximal small bowel, and showed improved overall cleansing of the distal small bowel when compared with 10-hours overnight fasting. Pathological lesions of the proximal and distal small bowel were, respectively, achieved in 82 and 74 patients, mostly distributed in group D. Small bowel preparation that involves split-dose oral mannitol plus single-dose simethicone for CE can improve mucosal visualization and subsequent diagnostic yield when compared with 10-hours overnight fasting.

    Many studies have linked irritable bowel syndrome (IBS) with small intestinal bacterial overgrowth (SIBO), although they have done so on a qualitative basis using breath tests even though quantitative cultures are the hallmark of diagnosis. The purpose of this study was to underscore the frequency of SIBO in a large number of Greeks necessitating upper gastrointestinal (GI) tract endoscopy by using quantitative microbiological assessment of the duodenal aspirate. Consecutive subjects presenting for upper GI endoscopy were eligible to participate. Quantitative culture of aspirates sampled from the third part of the duodenum during upper GI tract endoscopy was conducted under aerobic conditions. IBS was defined by Rome II criteria. Among 320 subjects enrolled, SIBO was diagnosed in 62 (19.4%); 42 of 62 had IBS (67.7%). SIBO was found in 37.5% of IBS sufferers. SIBO was found in 60% of IBS patients with predominant diarrhea compared with 27.3% without diarrhea (P = 0.004). Escherichia coli, Enterococcus spp and Klebsiella pneumoniae were the most common isolates within patients with SIBO. A step-wise logistic regression analysis revealed that IBS, history of type 2 diabetes mellitus and intake of proton pump inhibitors were independently and positively linked with SIBO; gastritis was protective against SIBO. Using culture of the small bowel, SIBO by aerobe bacteria is independently linked with IBS. These results reinforce results of clinical trials evidencing a therapeutic role of non-absorbable antibiotics for the management of IBS symptoms.

    A volvulus, which is torsion of the bowel and its mesentery, is a medical emergency. Small bowel volvulus rarely occurs in adults, although it has been reported in the presence of small bowel diverticulum. Multislice computed tomography (CT) angiography, by demonstrating the mesenteric vessels, can be of help in the diagnosis of small bowel volvulus, especially when CT or gastrointestinal studies fail to show the diverticulum. We present the multislice CT angiography findings of a 64-year-old woman with chronic intermittent volvulus resulting from jejunal diverticulosis, surgically confirmed. To our knowledge, no similar case has been reported previously in the literature.

    While jejunoileal diverticula are rare and often asymptomatic, they may lead to chronic non-specific or acute symptoms. The large majority of complications present with an acute abdomen similar to appendicitis, cholecystitis or colonic diverticulitis but they also may appear with atypical symptoms. As a result, diagnosis of complicated jejunoileal diverticulosis can be quite difficult, and may solely depend on the result of surgical exploration. In the absence of contra-indications, diagnostic laparoscopy has the benefit of thorough examination of the abdominal contents and helps to reach an absolute diagnosis. Surgical resection of the involved small-bowel segment with primary anastomosis is the preferred treatment in patients with symptomatic complicated jejunoileal diverticular disease. An atypical presentation of complicated jejunal diverticulitis in conjunction with sigmoid diverticulitis diagnosed with laparoscopy and treated with surgical resection is presented. PMID:17465510

    The authors assessed the morphological profile of tumor masses belonging to the small bowel discovered in their daily practice. 31 tumor masses located in different segments of small intestine operated between 2002 and 2013 in the 1st Surgical Department, Emergency County Hospital of Craiova, Romania, were analyzed. The investigated parameters were: tumor location and number, tumor dimensions, gross assessment, tumor extension and histological assessment. Tumor masses belonging to small intestine were rare. They usually expressed by their complications. In many cases, they were placed at the extremities of the small intestine. They were usually small but sometimes large and developing outwards intestinal wall. Commonly they had a fungating and ulcerated appearance. They were rather of mesenchymal origin than epithelial. However, some of them were inflammatory pseudotumors. Almost all neoplastic proliferations had a malignant phenotype, most often with regional extension. Our series of tumors had a morphological profile somehow similar with the profile described in the literature but with some particularities: the polarization to the extremities of the intestinal segment, a significant number of large tumors, clinical expression through different complications, the balance inclined in favor of mesenchymal origin of tumors and the clear predominance of malignant aggressive phenotype.

    To evaluate the usefulness of CT for the diagnosis of the cause and localization of small bowel obstruction. Out of a group of children who underwent a CT examination for a suspected small bowel obstruction, 19 patients with confirmed underlying disorders were identified and included in the study. Neonates and patients with duodenal obstruction were excluded from the study. The CT findings were analyzed for the location of obstruction site, abnormalities of the mesentery and mesenteric vessels, bowel wall thickening, closed loop obstruction, and strangulation. The obstruction site was divided into five parts. The preoperative CT diagnosis was compared with the final diagnosis. Causes of small bowel obstruction were intussusception (n = 6), appendiceal perforation (n = 4), transmesenteric internal hernia (n = 2), postoperative bands (n = 1), idiopathic multiple bands (n = 1), a foreign body (n = 1), a small bowel adenocarcinoma (n = 1), Meckel's diverticulitis (n = 1), tuberculous peritonitis (n = 1) and Salmonella enteritis with bowel perforation (n = 1). The CT findings showed mesenteric vascular prominence (n = 13), omental or mesenteric infiltration (n = 10), localized bowel wall thickening (n = 7) closed loops obstruction (n = 3) and strangulation (n = 1). The obstruction site was identified in all cases. The causes of obstruction could be diagnosed preoperatively in 14 cases, but a preoperative diagnosis was difficult in 5 cases. The causes of small bowel obstruction in children are variable, and CT is useful for evaluating the cause and localization of small bowel obstruction.

    Full Text Available Abstract Background Carcinoma of the colon may present with perforation proximal to the site of malignancy. Caecum is the commonest site of perforation if the ileocecal valve is patent and the jejunal and ileal perforations are very rare. Case presentation A 35 year male presented with intestinal obstruction. Emergency laparotomy revealed carcinoma of the transverse colon with multiple pinpoint perforations along antimesenteric border of ileum, which were wrapped with omentum, and no peritoneal contamination was present. Extended right hemicolectomy with jejunocolic anastomosis was done. Patient made uneventful recovery in postoperative period and was treated with adjuvant chemotherapy. Conclusion Patients with colonic carcinoma and incompetent ileocecal valve may present with intestinal perforation. Increased intraluminal pressure and closed loop obstruction may lead to ischemia and perforation of the small bowel.

    Full Text Available We report a case of a 64-year-old lady who developed clinical features of Wernicke-Korsakoff syndrome following a laparotomy for small bowel obstruction. Following the operation she developed paralytic ileus and required total parenteral nutrition for one month. A suspected history of average 40 units of weekly alcohol consumption prior to the operation could not be confirmed and the patient did not show any sign of alcohol dependence. Within a few months of treatment with a daily oral dose of thiamine 200 mgs supplemented by multivitamins the patient showed subjective evidence of improvement in confusion, confabulation, and anterograde amnesia, although objective tests showed residual deficits in many areas of cognitive functioning, including immediate and delayed recall of verbal and non-verbal materials, planning and switching of attention.

    Early postoperative small bowel obstruction is associated with considerable morbidity and mortality but has not been well documented in the era of laparoscopic surgery for colorectal cancer. Consecutive patients who had undergone laparoscopic resection for colorectal cancer were studied. In total, 1787 patients (105 with and 1682 without early postoperative small bowel obstruction) with colorectal cancer requiring laparoscopic colorectal surgery were evaluated in this study. Ten patients (0.56% among the total patient population, 9.5% among patients who experienced early postoperative small bowel obstruction) who did not respond to conservative treatment for more than 14 days required surgical intervention. Multivariate analysis showed that male sex (adjusted odds ratio [AOR]=2.27), combined operation (AOR=2.23), and diverting stoma (AOR=4.79) were associated with a higher early postoperative small bowel obstruction rate. For factors related to surgical difficulty, open conversion (AOR=2.85), blood transfusion (AOR=3.51), and an operation time longer than 180 minutes (AOR=1.91) were independent factors associated with an increased early postoperative small bowel obstruction rate. Early postoperative small bowel obstruction following laparoscopic resection for colorectal cancer occurred in 5.9% of patients. Factors for predicting the development of early postoperative small bowel obstruction in patients with colorectal cancer are variables reflective of a more difficult surgery, rather than pathologic disease severity or anatomical location. In addition, most patients with early postoperative small bowel obstruction improved with conservative treatment, and surgical treatment was rarely needed.

    The radiological diagnostics of diseases of the small intestine have undergone a great change in the last two decades. Through rapid progress with new treatments and an increasing therapeutic focus on transmural healing, a complete evaluation of the gastrointestinal tract is now crucial. With the introduction of endoscopy, gastrointestinal imaging with a relatively high radiation exposure had only limited applications. The development of cross-sectional imaging allowed a much broader radiological evaluation of abdominal diseases. Due to rapid investigation techniques, excellent soft tissue contrast and the distinct advantage of eliminating exposure to radiation, magnetic resonance imaging (MRI) of the gastrointestinal tract has gained increasing importance. With sufficient filling of the intestinal lumen, simultaneous imaging of all the intestinal wall layers, the perienteric structures and associated abdominal pathologies is now possible. New MR sequences, such as diffusion-weighted sequences, dynamic contrast-enhanced sequences and MR fluoroscopy, enable the detection of morphological changes, with additional characterization of affected bowel loops as well as the assessment of functional pathologies with dynamic information about intestinal motility disturbances. Recent guidelines of European radiological and gastroenterological organizations have confirmed the importance of cross-sectional imaging and particularly of MRI for diagnostics and follow-up in patients with Crohn's disease. Due to the possibility of assessment of all the layers of the intestinal wall and the presence of extramural complications, MRI has a significant impact on further therapeutic treatment in patients with inflammatory bowel disease. Especially in patients with inflammatory bowel disease, MR enterography and MR enteroclysis should be the methods of choice for the evaluation of small bowel pathologies because of radiation issues and the great diagnostic value they provide.

    Oudkerk, M.; Rijke, A.M.

    1988-01-01

    Although enteroclysis may have many advantages over the conventional methods of small bowel examination, the contrast material is not always infused at a rate appropriate to gain maximum diagnostic information. In this study, 190 patients were examined by small bowell enteroclysis at five contrast infusion rates ranging from 50 to 150 ml/min using a newly designed infusion pump system. The results show that at rates above 75 ml/min, motility disturbances are masked by small bowel dilatation and paralysis, transit times are extended and morphological detail is obscured. At rates below 75 ml/min, incomplete filling of the loops renders optimal diagnostic evaluation impossible. An infusion rate of 75 ml/min was found to be optimal for initiating small bowel studies. This rate can be adjusted for individual cases when pathology or drugs affect the motility of the small bowel. 13 refs.; 5 figs.; 1 table

    2011-01-01

    Full Text Available We report the unusual case of a 45-year-old woman who presented with multiple episodes of small bowel obstruction. Initial exploratory lap-roscopy did not reveal an etiology of the obstruction. Subsequent upper endoscopy identified a non-obstructing gastric trichobezoar which could not be removed endoscopically but was not thought to be responsible for the small bowel obstruction given its location. One week postoperatively, the patient experienced recurrence of small bowel obstruction. Repeat endoscopy disclosed that the trichobezoar was no longer located in the stomach and upon repeat laparotomy was extracted from the mid-jejunum. In the following 8 months, the patient had no further episodes of small bowel obstruction. Consequently, gastric bezoars should be included in the differential diagnosis of recurrent small bowel obstruction.

    Concealment of illicit drugs within the alimentary tract is now an established method used by both smugglers and traffickers to evade detection by authorities. Those who ingest wrapped packets of drugs to transport them across international borders are known as 'body packers,' whereas those who ingest packages of drugs upon an unexpected encounter with law enforcement agents are known as 'body stuffers' or 'quick swallowers. Although most of these individuals require no medical care, acute drug toxicity (from inadvertent leaking of contents or rupture of the drug packet) and bowel obstruction are recognized hazards of drug packet ingestion. The detection of these packets is a challenge to custom officials and police interested in preventing the import and trafficking of illegal drugs, as well as to physicians who have to treat individuals who have ingested them. We report a case of a 38-year-old intravenous drug abuser who presented with an acute small bowel obstruction secondary to an impacted intraluminal heroin balloon in the mid jejunum. The value of computed tomography (CT) in the patient's diagnostic evaluation is highlighted. (author)

    The male predominance of the two main histologic malignancies of the small bowel cancer may reflect a role of sex hormones which will be examined in this study. This was a nationwide population-based nested case-control study, based on a cohort of subjects born between 1932 and 2008, as identified in the Swedish Multi-Generation Register. For each case of small bowel cancer, 10 age- and sex-matched controls were randomly selected. Number of children and age at having the first child were analyzed in relation to the risk of small bowel cancer using conditional logistic regression, providing odds ratios (ORs) and 95 % confidence intervals (CIs). A total of 632 female cases and 894 male cases of small bowel cancer were included. No overall increased risk of small bowel cancer was found in parous compared to non-parous women (OR = 1.02, 95 % CI 0.67-1.54). There was no association between age at first birth and small bowel cancer (>30 years of age vs bowel. No distinct risk patterns were discerned in men compared to women. Reproductive history does not seem to be associated with the risk of small bowel cancer, independent of histologic type.

    We wished to evaluate the usefulness of helical CT for the diagnosis of strangulation of the dilated small bowels. The CT scans of 31 patients with small bowel obstruction from various causes were reviewed retrospectively. Thirteen of these patients were confirmed as small bowel strangulation by surgery and pathology. Fourteen patients underwent surgery, but they had no strangulation. Three patients were reduced by using a nasogastric tube and one infant with intussusception was reduced by air reduction. The following CT findings of strangulation were evaluated: reduced bowel wall enhancement by visual assessment and measuring the HU, ascites, thickening of bowel wall, abnormal mesenteric vessel location and whirlpool appearance, and mesenteric venous engorgement. For the precise evaluation of reduced bowel wall enhancement, the HUs were measured by 1 mm{sup 2} of ROI, and the differences of HUs between the well enhanced bowel and poorly enhanced bowel were compared. For the diagnosis of strangulation, measurement of HU of the bowel wall could improve the sensitivity from 69% to 100%. The specificity of both methods, by visual assessment and measurement of HU, was 94%. Ascites had a sensitivity of 69% and specificity of 44%. Thickening of bowel wall had a sensitivity of 38% and specificity of 78%. Abnormal mesenteric vessel location and whirlpool appearance had a sensitivity of 38% and specificity of 83%. Mesenteric venous engorgement had a sensitivity of 31% and specificity of 72%. Measurement of HU of the bowe wall after contrast enhancement can be a useful method in the differential diagnosis between the strangulated and non-strangulated bowels in patients with small bowel obstruction.

    Imaging methods provide an important diagnostic basis to clarify mesenteric ischemia. Angiography is the definitive method of investigation in such cases. Other noninvasive methods such as ultrasonography, computed tomography, and magnetic resonance imaging must still prove their importance. We describe three cases of unspezific abdominal pain where the CT shows a mesenteric venous thrombosis with an infarcted bowel. The venous infarcted bowel is clearly demonstrated by CT when other signs for MTV such as ascites, bowel wall thickening, bowel dilatation, and pneumatosis intestinalis are present. CT seems to be a good procedure in order to identify unspecific abdominal pain as being caused by a vascular insufficiency. (orig.) [de

    Acute bowel ischemia (ABT) is a life-threatening condition which most often effects elderly patients. It requires an intensive treatment and quick diagnosis. Unfortunately ABI manifested not only by specific but also various nonspecific clinical or laboratory finding. The radiological symptoms of the bowel ischemia are also differentiated and often nonspecific while the specific findings are rather uncommon.That is why the knowledge of the bowel ischemia pathogenesis and possible CT findings is so important for the correct diagnosis. The our paper, we present the radiological findings of the acute bowel ischemia based on the analysis of the patients' abdominal -CT examination. The purpose of our study is to MDCT in patients with acute bowel ischemia. The material of this study consists of four computer tomography examinations - three of those an angio-CT and one abdominal - in patients with acute abdomen symptoms. The result revealed the mesenteric thrombosis in two cases, and mesenteric artery stenosis in one case. In one case, the thrombus was present in the abdominal aorta. In conclusion, we claim that the MDCT should be the modality of choice for the diagnosis of the acute bowel ischemia. (author)

    Full Text Available BACKGROUND Irritable Bowel Syndrome (IBS is a common functional disorder and the pathophysiology of IBS is poorly understood. The aim of the study is to assess the prevalence of SIBO in patients with IBS using Lactulose Hydrogen Breath Test (LHBT. Diagnosis of IBS was made according to the Rome III Criteria and Lactulose Hydrogen Breath Test (LHBT was done. MATERIALS AND METHODS The current hypothesis suggests that altered gastrointestinal motility, disturbance of visceral hypersensitivity and infection may contribute to the symptoms. Gut microbiota and intestinal pathogens are likely to influence the pathogenesis of IBS. Small Intestinal Bacterial Overgrowth (SIBO is defined as an abnormally high bacterial count (≥105 colony-forming units/mL in the proximal small intestine. RESULTS Out of the 120 patients, 9 were LHBT positive (7.5% compared to none in controls (p <0.01. IBS patients with LHBT positivity was correlated well with the increased frequency of stools. There was no correlation noted with LHBT positivity and abdominal pain or flatulence or bloating compared to IBS patients who were LHBT negative. CONCLUSION These findings may suggest that patients with chronic diarrhoea including IBS should be tested for SIBO. Our study also showed that LHBT positivity is associated with increased frequency of stools and diarrhoea. If SIBO is found in patients with chronic diarrhoea, specific treatment with antibiotics may benefit them.

    Adenoviruses are emerging as important viral pathogens in hematopoietic stem cell and solid organ transplant recipients, impacting morbidity, graft survival, and even mortality. The risk seems to be highest in allogeneic hematopoietic stem cell transplant recipients as well as heart, lung, and small bowel transplant recipients. Most of the adenovirus diseases develop in the first 6 months after transplantation, particularly in pediatric patients. Among abdominal organ recipients, small bowel grafts are most frequently affected, presumably due to the presence of a virus reservoir in the mucosa-associated lymphoid tissue. Management of these infections may be difficult and includes the reduction of immunosuppression, whenever possible, combined with antiviral therapy, if necessary. Therefore, an awareness of the pathology associated with such infections is important in order to allow early detection and specific treatment. We reviewed six transplant recipients (small bowel, kidney, and heart) with adenovirus graft involvement from two institutions. We sought to compare the diagnostic morphology and the clinical and laboratory findings. The histopathologic features of an adenovirus infection of the renal graft and one native kidney in a heart transplant recipient included a vaguely granulomatous mixed inflammatory infiltrate associated with rare cells showing a cytopathic effect (smudgy nuclei). A lymphocytic infiltrate, simulating T cell rejection, with admixture of eosinophils was also seen. In the small bowel grafts, there was a focal mixed inflammatory infiltrate with associated necrosis in addition to cytopathic effects. In the heart, allograft adenovirus infection was silent with no evidence of inflammatory changes. Immunohistochemical stain for adenovirus was positive in all grafts and in one native kidney. All patients were subsequently cleared of adenovirus infection, as evidenced by follow-up biopsies, with no loss of the grafts. Adenovirus infection can

    Introduction: The main role of the radiologist in the management of patients with suspicion of small bowel obstruction is to help triage patients into those that need immediate surgical intervention from those that require medical therapy or delayed surgery. Ultrasound examination is usually considered not helpful in bowel obstruction because of air in the intestinal lumen that interferes the evaluation of the intestinal loops, however recently some Authors attested the increasing important role of sonography in the acute abdominal disease. Aim of our report is to demonstrate the value of free fluid detected by US in differentiating between low and high-grade small bowel obstruction. Materials and methods: The study is based on 742 consecutive patients who presented symptoms of the acute abdomen; all patients had undergone initial serial abdominal plain film and US examinations prior to any medical intervention. We reviewed the imaging findings of 150 cases in whom small bowel obstruction was clinically suspected and confirmed at surgery. We consider the following radiographic and US findings: dilatation of small bowel loops; bowel wall thickness; presence of air-fluid levels; thickness of valvulae conniventes; evidence of peristalsis; presence and echogenicity of extraluminal fluid. We looked at the value of extraluminal peritoneal fluid at US examination in differentiating low and high-grade small bowel obstruction based on the surgical outcome. Results: In 46 patients altered peristaltic activity, thin bowel walls, fluid filled loops with hyperechoic spots in the bowel segment proximal to obstruction were noted at US, whereas radiographic features were: moderate dilatation of small bowel loops, with thin bowel wall and evidence of numerous and subtle valvulae conniventes; presence of air-fluid levels was also noted. In 70 other patients, US examination revealed all the findings described in the precedent cases and also the presence of free extraluminal fluid

    Small bowel diverticulosis (SBD) is a rare condition. In most cases it is asymptomatic, but sometimes it can be manifested with chronic non-specific or acute symptoms. Because of the absence of pathognomonic signs and symptoms and truly reliable diagnostic tests, SBD is hard to diagnose and this is usually done incidentally by radiographic examination or during laparatomy. For uncomplicated patients, those with chronic abdominal pain, syndromes of malabsorption related to jejunoileal diverticulosis, bacterial overgrowth or an episode of intestinal obstruction, as in our case, conservative management is the initial option for treatment. A case of a patient with obstructive symptoms of the gastrointestinal tract due to SBD that was conservatively treated and had a positive outcome is presented.

    The effects of the volume of irradiated small bowel on late small-bowel tolerance was studied, taking into account the equivalent total dose ant type of pre-irradiation surgical procedure. A method was developed to estimate small-bowel volumes in the high-bowel volumes were measured for three-field and AP-PA pelvic treatments (165 cm 3 and 400 cm 3 , respectively), extended AP-PA treatment of para-aortic and iliac nodes (1000 cm 3 ). In a retrospective study of 111 patientst irradiated after surgery for rectal or recto-sigmoid cancer to a dose of 45-50 Gy in 5 weeks, extended AP-PA pelvic treatment (n = 27) resulted in a high incidence of severe small-bowel complications (37%), whereas for limited (three-field) pelvic treatment (n = 84) the complication rate was 6%. These complication data together with data from the literature on postoperative radiation-related small-bowel complications were analysed using the maximum likelihood method to fit the data to the logistic form of the dose-response relation, taking the volume effect into account by a power law. The analysis indicated that the incidence of radiation-related small-bowel compllications was higher after rectal surgery than after other types of surgery, which might be explained by the development of more adhesions. For both types of surgery a volume exponent of the power-law of 0.26 ± 0.05 was established. This means that if the small-bowel volume is increased by a factor of 2, the total dose has to be reduced by 17% for the same incidence of small-bowel complications.

    Twelve patients undergoing scintigraphy with Tc-99m-labeled red blood cells (RBC) exhibited abnormal small-bowel activity and were given glucagon to assess its role in detecting bleeding from the small bowel. Six demonstrated focal accumulation of activity which was not identified prior to glucagon. Endoscopy, barium studies, angiography, and colonoscopy located the small-bowel bleeding site in 4 patients; in the other 2, studies of the colon failed to show the bleeding site and the origin was presumed to be the small bowel. The authors suggest that intravenous glucagon can be beneficial as an adjuvant to Tc-99m-RBC when diagnosing bleeding from the small bowel

    Small bowel obstruction (SBO) is commonly encountered by surgeons and has traditionally been handled via an open approach, especially when small bowel resection (SBR) is indicated, although recent series have shown improved outcomes with a laparoscopic approach. In this retrospective study, we sought to evaluate outcomes and identify risk factors for adverse events after emergency SBR for SBO with an emphasis on surgical approach. In this retrospective review using American College of Surgeons National Surgical Quality Improvement Program data, 1750 patients were identified who had emergency SBR with the principal diagnosis of SBO from 2006 to 2011. Mortality and postoperative adverse events were evaluated. Of 1750 patients who had emergency SBR, 51 (2.9%) had laparoscopic bowel resection (LBR). There was no difference in surgery duration (open bowel resection [OBR] versus LBR, 100 minutes versus 92 minutes; P=.38). Compared with the LBR group, the OBR group had a higher rate of baseline cardiac comorbidities and postoperative complications, and their length of stay was longer (10 versus 8 days; P70 years, pulmonary, renal, neurological, and cardiac comorbidities, preoperative sepsis, steroid use, and body mass index of surgical problem.

    For radiotherapy in rectal cancer patients treated with small bowel displacement device (SBDD) and belly board, We will suggest new indication of using SBDD depending on obesity index by analyzing correlation between obesity and irradiated small bowel volume. In this study, We reviewed 29 rectal cancer patients who received pelvic radiation therapy with belly board and SBDD from January to April in 2012. We only analyzed those patients treated with three-field technique (PA and both LAT) on 45 Gy (1.8 Gy/fx). We measured patients' height, weight, body mass index (BMI), waist-hip ratio (WHR) and divided BMI into two groups.(≥23:BMI=group 1, <23:BMI=group 2) We performed a statistical analysis to evaluate correlation between total volume of bladder (TV bldder ), obesity index and high dose volume of small bowel (small bowel volume irradiated at 90% of prescribed dose, HDV sb ), low dose volume of small bowel (small bowel volume irradiated at 33% of prescribed dose, LDV sb ). The result shows, gender, WHR and status of pre operative or post operative do not greatly affect HDV sb and LDV sb . Statistical result shows, there are significant correlation between HDV sb and BMI (p<0.04), HDV sb and TV bladder (p<0.01), LDV sb and TV bladder (p<0.01). BMI seems to correlate with HDV sb but does not with LDV sb (p>0.05). There are negative correlation between HDV sb and BMI, TV bladder and HDV sb , TV bladder and LDV sb . Especially, BMI group1 has more effective and negative correlation with HDV sb (p=0.027) than in BMI group 2. In the case of BMI group 1, TV bladder has significant negative correlation with HDV sb and LDV sb (p<0.04). In conclusions, we confirmed that Using SBDD with belly board in BMI group 1 could more effectively reduce irradiated small bowel volume in radiation therapy for rectal cancer. Therefore, We suggest using belly board with SBDD in order to reduce the small bowel toxicity in rectal radiotherapy, if patients' BMI is above 23

    While enteroclysis seems to be the most efficacious method in achieving bowel distension, enterographic methods have become widespread due to the unpleasantness of enteroclysis and the radiation involved with positioning the catheter. Cine images in MRI can be done without radiation. Our aim is to see if and how cine MR imaging can improve visualization of bowel loops by capturing them while distended. Ten healthy individuals were asked to drink up to 2,000 ml of an oral solution made locally over a 60-min period. Then they underwent MRI using coronal balanced fast field echo (b-FFE) covering small bowel loops. If the initial exam revealed collapsed bowel loops an additional 50 mg of erythromycine was given intravenously with the subject still in the scanner and then cine imaging was performed. The degree of distension of different segments of the small bowel was measured before and after cine imaging and compared. The distension score was significantly higher after addition of the cine images as well, being only significant for depiction of the duodenum and jejunum. Our preliminary study suggests that cine MRI can give better image depiction of the proximal small bowel in healthy volunteers, perhaps circumventing the need for enteroclysis in some cases. There is a need for validation of these results in patients with small bowel disease. (orig.)

    Ascariasis is one of the most common helminthic disease worldwide and evoked variable clinical manifestations by the migration of worm in the alimentary and biliary tract. The ultrasonographic detection of ascaris in the small bowel is relatively difficult, and no report on the ultrasonographic findings have been published in Korea. On abdominal ultrasonography, ascaris is seen as an intraluminal tubular structure with 4 linear echogenic stripes and movement. We report a case of ascaris in the small bowel detected by abdominal ultrasonography.

    Background: Adhesion formation is a widely acknowledged risk following abdominal or pelvic surgery. Adhesions in the abdomen or pelvis can cause or contribute to partial or total small bowel obstruction (SBO). These adhesions deter or prevent the passage of nutrients through the digestive tract, and may bind the bowel to the peritoneum, or other organs. Small bowel obstructions can quickly become life-threatening, requiring immediate surgery to resect the bowel, or lyse any adhesions the surg...

    Respective radiation doses and total examination and fluoroscopy times were compared for 50 patients; 25 underwent enteroclysis and 25 underwent small bowel series with (n = 17) and without (n = 8) an examination of the upper gastrointestinal (GI) tract. For enteroclysis, the mean skin entry radiation dose (12.3 rad (123 mGy)) and mean fluoroscopy time (18.4 minutes) were almost 1 1/2 times greater than those for the small bowel series with examination of the upper GI tract (8.4 rad (84 mGy); 11.4 minutes) and almost three times greater than those for the small bowel series without upper GI examination (4.6 rad (46 mGy); 6.3 minutes). However, the mean total examination completion time for enteroclysis (31.2 minutes) was almost half that of the small bowel series without upper GI examination (57.5 minutes) and almost four times shorter than that of the small bowel series with upper GI examination (114 minutes). The higher radiation dose of enteroclysis should be considered along with the short examination time, the age and clinical condition of the patient, and the reported higher accuracy when deciding on the appropriate radiographic examination of the small bowel.

    Background. Small bowel peristalsis is a complex of many individual motion elements. Although each element of peristalsis can be measured there is no current global measure of peristalsis. Purpose. To examine the feasibility of automated computerized assessment of global small bowel motility using simple computational methods. Material and Methods. Coronal dynamic MR images were obtained from five healthy volunteers who had fasted for 9 h and drunk 1.5 L of water. Images were taken using single breath-hold and ECG triggering. Acquisitions were repeated at 10 and 20 min after an intramuscular injection of hyoscine butylbromide. Parametric maps were generated representing the mean change in signal amplitude (MSA) per voxel for each dynamic acquisition. Two observers independently assessed thresholding for optimal segmentation of small bowel from other sources of signal. Total voxel activity (TVA) for each study was calculated as a sum of MSA per slice and whole examination and TVA profiles were generated. Results. Independent observations suggest that the automated segmentation method described usefully segments small bowel activity from other signal. Small bowel movement represented as TVA varied three-fold in the five volunteers and was inhibited by anti-muscarinic injection. Conclusion. It is possible to develop a new measure, based on automated segmentation of mean signal amplitude changes, of small bowel peristalsis using dynamic MR

    To identify CT findings predictive of surgical management in non-emergency small bowel obstruction (SBO). Contrast-enhanced abdominal CT of 129 patients with non-emergency SBO were evaluated for small bowel luminal diameter, wall thickness, presence of the small bowel faeces sign (intraluminal particulate matter in a dilated small bowel) and length, transition point, submucosal oedema, mesenteric stranding, ascites and degree of obstruction (low grade partial, high grade partial and complete obstruction). Medical records were reviewed for age, gender, management and history of abdominal surgery, abdominal malignancy, or SBO. Statistical analyses were performed with Stata Release 9.2. Degree of obstruction was the only predictor of need for surgery. Whereas 18.0% of patients with low-grade partial obstruction (n = 50) underwent surgery, 32.5% of patients with high-grade partial obstruction (n = 77) and 100% of patients with complete obstruction (n = 2) required surgery (P = 0.004). The small bowel faeces sign was inversely predictive of surgery (P = 0.018). In non-emergency SBO patients with contrast-enhanced CT imaging, grade of obstruction predicts surgery, while the small bowel faeces sign inversely predicts need for surgery. (orig.)

    Respective radiation doses and total examination and fluoroscopy times were compared for 50 patients; 25 underwent enteroclysis and 25 underwent small bowel series with (n = 17) and without (n = 8) an examination of the upper gastrointestinal (GI) tract. For enteroclysis, the mean skin entry radiation dose (12.3 rad [123 mGy]) and mean fluoroscopy time (18.4 minutes) were almost 1 1/2 times greater than those for the small bowel series with examination of the upper GI tract (8.4 rad [84 mGy]; 11.4 minutes) and almost three times greater than those for the small bowel series without upper GI examination (4.6 rad [46 mGy]; 6.3 minutes). However, the mean total examination completion time for enteroclysis (31.2 minutes) was almost half that of the small bowel series without upper GI examination (57.5 minutes) and almost four times shorter than that of the small bowel series with upper GI examination (114 minutes). The higher radiation dose of enteroclysis should be considered along with the short examination time, the age and clinical condition of the patient, and the reported higher accuracy when deciding on the appropriate radiographic examination of the small bowel

    Evidence indicates that irritable bowel syndrome can occur after gastroenteritis. However, little is known about its incidence after diverticulitis. This study was designed to identify the incidence and risk factors of irritable bowel syndrome after diverticulitis in Korea. A survey regarding irritable bowel syndrome was performed in patients allocated to the cases hospitalized for acute diverticulitis and controls hospitalized for non-gastrointestinal disorders between January 2007 and June 2012. Patients meeting criteria for irritable bowel syndrome before hospitalization or with a history of bowel resection were excluded for analysis. Response rate of telephone interviews was 28.1 % (139 of 494) and 73.3 % (220 of 300) in cases and controls, respectively. After exclusion, 102 patients in the cases and 205 patients in the controls were analyzed. At 31 months median follow-up, irritable bowel syndrome had developed in 13 patients (12.8 %) in the cases and 11 patients (5.4 %) in the controls with significant statistical difference (p = 0.02). No clinical difference was seen between the two groups. No clinical factor was significant for the development of irritable bowel syndrome after diverticulitis, and no independent factor was associated with the development of irritable bowel syndrome. Among the 13 patients who developed post-diverticulitis irritable bowel syndrome, the diarrhea-predominant type (53.9 %) was most common. A higher incidence of irritable bowel syndrome after diverticulitis was evident in this study. However, no clinical feature for prediction of its development after diverticulitis was found. Further large-scale analysis will be needed to generalize this result.

    Examinations using ionizing radiation are frequently used in the evaluation of disease activity in children affected by idiopathic inflammatory bowel disease (IBD). To develop an MR imaging protocol without the need for fluoroscopic insertion of an enteral tube and to assess the disease activity in children with IBD. Included in the study were 37 children (22 girls and 15 boys; age range 7-15 years, mean 11.67 years) with IBD who underwent MR imaging of the small bowel. Of these 37 children, 32 had Crohn disease and 5 had indeterminate colitis. A water solution containing herbal fibres was administered orally or through a nasogastric tube. Patients were imaged on a 1.5-T MR scanner with T1-weighted and {tau}2-weighted sequences followed by a dynamic study using 3-D T1-W images after intravenous administration of gadolinium. The percentage enhancement of the bowel wall was significantly increased in patients with abnormal C-reactive protein (CRP) values compared to patients with CRP values in the normal range (P<0.001). A relatively weak but significant correlation between percentage enhancement of the bowel wall and CRP values was noted during all phases of enhancement. This MR imaging protocol is a safe and well-tolerated method for evaluating disease activity and extraintestinal manifestations of IBD in children. (orig.)

    Diarrhea is common in HIV/AIDS patients, caused by both classic enteric pathogens and different opportunistic agents. Infection with these different pathogens may lead to similar radiological findings, thus causing diagnostic confusion. A 30-yr-old female with AIDS presented with chronic diarrhea of 4 months duration. She had diffuse small bowel thickening present on CT scan of her abdomen, with stool examination showing no parasites. She was erroneously diagnosed as abdominal tuberculosis and given antituberculosis drugs with which she showed no improvement. Repeat stool examination later at a specialized laboratory revealed Cryptosporidium parvum infection.The patient was given an extended course of nitazoxanide treatment, as her stool examination was positive for Cryptosporidium parvum even after 2 weeks of drug consumption. Parasite clearance was documented after 10 weeks of treatment. Interestingly, the bowel thickening reversed with parasitological clearance. Cryptosporidium parvum may lead to small bowel thickening in AIDS patients. This small bowel thickening may reverse following parasitological clearance.

    Obesity is a major chronic disease affecting the U.S. population. Bariatric surgery has consistently shown greater weight loss and improved outcomes compared with conservative therapy. However, complications after bariatric surgery can be catastrophic, resulting in short bowel syndrome with a potential risk of intestinal failure, ultimately resulting in the need for a small bowel transplant. A total of 6 patients became dependent on home parenteral nutrition (HPN) after undergoing bariatric surgery at an outside facility. Four of the 6 patients required evaluation for small bowel transplant; 2 of the 6 patients were successfully managed with parenteral nutrition and did not require further small bowel transplant evaluation. Catheter-related bloodstream infection, a serious complication of HPN, occurred in 3 patients despite extensive patient education on catheter care and use of ethanol lock. Two patients underwent successful small bowel transplantation, 1 died before transplant could be performed, and 1 was listed for a multivisceral transplantation. Surgical procedures to treat morbid obesity are common and growing in popularity but are not without risk of serious complications, including intestinal failure and HPN dependency. Despite methods to prevent complications, failure of HPN may lead to the need for transplant evaluation. In selected cases, the best therapeutic treatment may be a small bowel transplant to resolve irreversible, post-bariatric surgery intestinal failure.

    The small bowel is a hollow organ involved in the transit and absorption of food. In relation to its anatomical location, a significant amount of this organ is exposed in whole or in part to ionizing radiation in external radiotherapy during abdominal or pelvic irradiation either for primary cancers or metastasis. The acute functional changes during external beam radiation are mainly leading to diarrhea, abdominal pain and bloating. The main late side effects of irradiation of the small intestine are chronic diarrhea, malabsorption with steatorrhoea, abdominal spasms, intestinal obstruction, bleeding and fistulas. The architecture of the small intestine may be considered as parallel with a significant correlation between the irradiated volume of small bowel and the likelihood of acute toxicity, whatever the dose. The literature analysis recommends to consider the volume of small bowel receiving 15 Gy (threshold of 100 to 200 cm{sup 3}) but also 30 and 50 Gy (thresholds of 35 to 300 cm{sup 3}, depending on the level of dose considered). Modern techniques of conformal radiotherapy with modulated intensity will probably have beneficial impact on small bowel toxicity. (authors)

    The purpose of this treatment planning study was to evaluate the efficiency of a commercial belly board device in reducing the irradiated volume of the small bowel. In this study 10 patients with rectal carcinoma receiving postoperative radiotherapy were included. For each of them we made two computer tomography series in prone position. In the first one the patients were lying on the flat table top, and in the second one they were lying on the belly board device which is under investigation. On both series we calculated and optimized plans according to the standing protocol of our department. From the dose-volume histograms of these plans we compared the volumes of the small bowel irradiated to three dose levels 15, 30 and 45 Gy. The results showed that the absolute irradiated volumes were significantly smaller in the plans with the belly board device. Based on these results we believe that the employment of this belly board device will reduce the acute and late small bowel toxicity. This should be verified with a clinical study.(Author)

    To study graft-versus-host reaction (GVHR) in small-bowel transplantation and its underlying mechanisms and to find methods for circumventing GVHR, we used an unidirectional GVHR model in which F1 Lewis (LEW) x Wistar King A (WKA) hybrid rats received small-bowel transplants from either LEW or WKA parent rats. The survival time of F1 hybrid rats that received full-length small-bowel transplantation from LEW and WKA was 16.3+/-2.1 days and 18.2+/-3.4 days, respectively. When one-quarter of LEW small bowel was transplanted to an F1 hybrid recipient, the survival time was significantly longer at 44.0+/-23.4 days compared with rats that had received full-length LEW small-bowel transplantation. The survival time of F1 hybrid rats which received an injection of high-dose (5 x 10(8) cells) LEW or WKA spleen cells was 11.9+/-4.0 days and 13.1+/-3.6 days, respectively. However, when an injection containing a low dose (1 x 108 cells) of LEW spleen cells was used, survival was > 100 days, showing significance compared with the survival of rats receiving the higher dose LEW spleen-cell injection. Both small-bowel transplantation and spleen-cell injection were compared for the effective period of recipient resistance to donor cell or small-bowel transplantation as second challenge. When the F1 rats given a quarter LEW small-bowel transplant as first challenge were treated with a high-dose of spleen cells 30 days after transplantation, they survived for > 30 days without GVHR. F1 rats that were treated with a low-dose LEW spleen-cell injection, followed 30 days later by full LEW small-bowel transplantation, had a survival time of > 100 days. These results indicate that segmental small-bowel transplantation and spleen-cell injection as first challenge may facilitate the prevention of GVHR, resulting in resistance to subsequent immunological challenge.

  18. An unusual cause of small bowel obstruction: Gossypiboma – case report

    2003-09-01

    Full Text Available Abstract Background The term "gossypiboma" denotes a mass of cotton that is retained in the body following surgery. Gossypiboma is a medico-legal problem especially for surgeons. To the best of our knowledge, the patient presented herein is the second reported patient in whom the exact site of migration of a retained surgical textile material into the intestinal lumen could be demonstrated by preoperative imaging studies. Case presentation A 74-year-old woman presented with symptoms of small bowel obstruction due to incomplete intraluminal migration of a laparotomy towel 3 years after open cholecystectomy and umbilical hernia repair. Plain abdominal radiography did not show any sign of a radio-opaque marker in the abdomen. However, contrast enhanced abdominal computerized tomography revealed a round, well-defined soft-tissue mass with a dense, enhanced wall, containing an internal high-density area with air-bubbles in the mid-abdomen. A fistula between the abscess cavity containing the suspicious mass and gastrointestinal tract was identified by upper gastrointestinal series. The presence of a foreign body was considered. It was surgically removed with a partial small bowel resection followed by anastomosis. Conclusions Although gossypiboma is rarely seen in daily clinical practice, it should be considered in the differential diagnosis of acute mechanical intestinal obstruction in patients who underwent laparotomy previously. The best approach in the prevention of this condition can be achieved by meticulous count of surgical materials in addition to thorough exploration of surgical site at the conclusion of operations and also by routine use of surgical textile materials impregnated with a radio-opaque marker.

    Purpose: To evaluate several substances regarding small bowel distension and contrast on balanced steady-state free precession (bSSFP) cine magnetic resonance (MR) images. Material and Methods: Luminal contrast was evaluated in 24 volunteers after oral application of two different contrast agent groups leading to either bright lumen (pineapple, blueberry juice) or dark lumen (tap water, orange juice) on T1-weighted images. Bowel distension was evaluated in 30 patients ingesting either methylcellulose or mannitol solution for limiting intestinal absorption. Fifteen patients with duodeno-jejunal intubation served as the control. Quantitative evaluation included measurement of luminal signal intensities and diameters of four bowel segments, qualitative evaluation assessed luminal contrast and distension on a five-point scale. Results: Quantitative and qualitative evaluation of the four contrast agents revealed no significant differences regarding luminal contrast on bSSFP images. Quantitative evaluation revealed significantly lower (P<0.05) small bowel distension for three out of four segments (qualitative evaluation: two out of four segments) for methylcellulose in comparison to the control. Mannitol was found to be equal to the control. Conclusion: Oral ingestion of tap water or orange juice in combination with mannitol is recommended for cine MR imaging of the small bowel regarding luminal contrast and small bowel distension on bSSFP sequences.

    2001-01-01

    Objective: The purpose of this study was to assess the frequency of isolated small bowel dilatation on abdominal radiographs in patients with colonic fecal impaction and also to elucidate the cause of this finding. Methods: A computerized search of radiology files revealed 515 patients with colonic fecal impaction on abdominal radiographs. The radiologic reports described isolated small bowel dilatation not related to other known causes of ileus or obstruction in 18 (3.5%) of the 515 patients. The films were reviewed to determine the distribution of fecal impaction and the degree and extent of small bowel dilatation. In 16 cases, medical records were reviewed to determine the clinical presentation, treatment, and course. Finally, follow-up radiographs were reviewed in four cases to determine the response to treatment of the impaction. Results: All 16 patients with available medical records had abdominal symptoms. The average diameter of the dilated small bowel on abdominal radiographs was 3.7 cm. Fourteen patients (78%) had a diffuse colonic fecal impaction (nine) or a predominantly right-sided fecal impaction (five) that involved the cecum, and the remaining four (22%) had a left-sided colonic fecal impaction. All 12 patients with clinical follow-up had resolution of symptoms and all four with follow-up radiographs had resolution of small bowel dilatation after treatment of the underlying impaction. Conclusion: Fecal impaction should be considered in the differential diagnosis of small bowel dilatation on abdominal radiographs, as treatment of the underlying impaction usually produces a dramatic clinical response with resolution of the small bowel dilatation on follow-up radiographs

    Full text: The aim of this study was to assess the effect of Trendelenburg position in comparison to prone position on small bowel volume and treatment dose in gynecologic pelvic external beam radiotherapy using three-dimensional con-formal treatment plans. Eight patients with gynecologic cancers, treated with definitive or postoperative pelvic radiotherapy were investigated. Pelvic computerized tomography (CT) scans for treatment planning were performed in prone and 25 degree Trendelenburg positions for each patient. The dose-volume histograms of small bowel within the treatment fields were obtained and compared for both positions. The clinical target volume (CTV) and the planning target volume (PTV) were also defined and evaluated in the subjects. Treatment dose was 5040 cGy to PTV with 180 cGy daily fraction doses in both techniques for all patients. The average irradiated small bowel volume was 726 cc for prone position and 458 cc for the Trendelenburg position. The average irradiated small bowel volume reduction in the Trendelenburg position was 38.0% (95% CI 19.5 ± 38%) compared with the prone position. The average small bowel percent dose was 25.4% (1280 cGy) for Trendelenburg position and 39.9% (2010 cGy) for prone position. PTV doses were similar in both techniques. The results of this dosimetric study suggest that gynecologic pelvic radiotherapy in the Trendelenburg position decreases the volume of irradiated small bowel compared to prone position and may decrease treatment related small bowel morbidity. Clinical benefit of this position should be evaluated in further clinical studies.

    Abdominal tuberculosis (TB) is the sixth most common extrapulmonary site of involvement. The sites of involvement in abdominal tuberculosis, in descending order of frequency, are lymph nodes, genitourinary tract, peritoneal cavity, and gastrointestinal tract. The radiological armamentarium for evaluating tuberculosis of the small bowel (SBTB) includes barium studies (small bowel follow-through, SBFT), CT (multidetector CT, CT enterography, and CT enteroclysis), ultrasound (sonoenteroclysis), and magnetic resonance imaging (MRI; enterography and enteroclysis). In this review, we illustrate the abnormalities at MDCT enterography in 20 consecutive patients with SB TB and also describe extraluminal findings in these patients. MDCT enterography allows non-invasive good-quality assessment of well-distended bowel loops and the adjacent soft tissues. It displays the thickness and enhancement of the entire bowel wall in all three planes and allows examination of all bowel loops, especially the ileal loops, which are mostly superimposed. The terminal ileum and ileocaecal junction are the most common sites of small bowel involvement in intestinal TB. The most common abnormality is short-segment strictures with symmetrical concentric mural thickening and homogeneous mural enhancement. Other findings include lymphadenopathy, ascites, enteroliths, peritoneal thickening, and enhancement. In conclusion, MDCT enterography is a comprehensive technique for the evaluation of SB TB

    Unlike ascariasis of the small bowel, taeniasis can be detected radiologically with much difficulty because of the basic difference between the morphological features of each helminth. However once the characteristics of tape worms are appreciated and kept in mind, radiological diagnosis is fairly accurately made. In the present study we have reported typical radiological features of the small bowel taeniasis as observed in 6 adults patients seen at the Department of Radiology of St. Mary's Hospital and Holy Family Hospital, Catholic Medical College. Tapering tape-like or ribbon -like radiolucent shadows in distal small bowel appear unique. Compression spot film study of the ileum is most important in revealing such findings. An animal experiment using the swine small intestine and parasitological specimen of evacuated worm of taenia saginata was designed to help understand radiological manifestation in vivo

    Contrast radiology predicts the outcome of treatment for patients with small bowel obstruction. The optimal method of contrast radiology to determine the indications for and timing of surgery is controversial. Contrast radiology was performed for patients with postoperative adhesive small bowel obstruction between April 1, 2000 and March 31, 2001. Nearly 40 mL of gastrografin mixed with 40 mL of water was administered either orally or via a nasogastric tube to each patient within 24 hours of hospital admission. Serial erect and supine plain abdominal radiographs were taken 4, 8, 16 and 24 hour later. Of 107 patients with postoperative adhesive small bowel obstruction, 97 patients had the examination completed. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of this study as an indicator for non-operative treatment were 98.9%, 66.6%, 96.9%, 97.8% and 80%. However, contrast radiology had little impact on the diagnosis of 6 patients with strangulated small bowel obstruction. Ninety-two of 93 patients (98.9%) who were resolved with non-operative treatment were resolved within 48 hours of hospitalization. Contrast radiology should be considered for patients with simple small bowel obstruction who did not improve with non-operative measures after 48 hours of hospitalization.

    Full Text Available Obscure gastrointestinal bleeding (OGIB is one of the common complications in patients with chronic kidney disease (CKD, especially those who are on maintenance hemodialysis (HD. However, little is known about the characteristics of the small-bowel lesions in these patients, or of the factors that could predict the presence of such lesions. Therefore we enrolled a total of 42 CKD patients (including 19 HD patients and 23 non-HD patients, and compared the incidence of the small-bowel lesions among two groups. Furthermore, to identify predictive factors for the presence of small-bowel lesions, we performed multivariate logistic-regression-analyses. The incidence of small-bowel vascular lesions was significantly higher in CKD patients than in age-and-sex matched non-CKD patients (P<0.001. On the other hand, there was any significant difference of the incidence of small-bowel lesions between HD and non-HD patients. In CKD patients, past history of blood transfusion (OR 5.66; 95% CI 1.10–29.1, P=0.04 was identified as an independent predictor of the presence of vascular lesions, and history of low-dose aspirin use (OR 6.00; 95% CI 1.13–31.9, P=0.04 was identified as that of erosive/ulcerated lesions. This indicated that proactive CE examination would be clinically meaningful for these patients.

    The prognosis of acute superior mesenteric venous thrombosis (SMVT) remains obscure. We aimed to investigate the treatment outcomes and possible risk factors for bowel infarction in these patients. We retrospectively included 66 patients with acute SMVT between January 2002 and June 2016. Each patient underwent contrast-enhanced computed tomography as part of the initial diagnosis. The standard protocol for management included a nonsurgical approach with early anticoagulation and selective exploration. For the analysis of the risk factors for bowel infarction, patients were divided into bowel resection (BR) and non-BR groups. Outcomes of interest were causes of SMVT, percentage of BR after nonsurgical treatment, and risk factors for BR. Of 66 patients, 15 (23%) underwent BR; of these, 9 underwent urgent BR because of peritoneal signs and definite findings of bowel infarction on computed tomography scan, 4 underwent BR after failed anticoagulation, and 2 underwent BR because of delayed stricture. Clinically, vomiting (P = .003), abdominal distention (P = .003), rebound tenderness (P = .005), and leukocytosis (P = .001) were associated with BR. On radiologic examination, bowel wall thickening (P thrombosis in addition to SMVT. All 15 BRs occurred in patients with combined PV thrombosis and SMVT (P thrombosis of the superior mesenteric vein and PV was also associated with BR (P = .028 for superior mesenteric vein; P = .025 for PV). BR was performed in 1 (4%) of 24 patients with transient risk factors compared with 14 (33%) of 42 patients without transient risk factors (P = .006). Three patients (4.5%) died in the hospital. In patients with acute SMVT, the extent of thrombus and etiology were associated with the severity of acute SMVT. Patients with transient risk factors and isolated SMVT tended to have a benign disease course. With early anticoagulation, acute SMVT does not seem to have the grave prognosis that is associated with arterial thrombosis

    Full Text Available Small bowel volvulus is a rare disease, which is also challenging to diagnose. The aims of this study were to characterize the clinical and radiological features associated with small bowel volvulus and treatment and to identify risk factors for associated small bowel necrosis.Patients with small bowel volvulus who underwent operations from January 2001 to December 2015 at the First Affiliated Hospital of China Medical University (Shenyang, China were reviewed. Clinical, surgical and postsurgical data were registered and analyzed.Thirty-one patients were included for analysis. Fifteen patients were female (48.4%, with an average age of 47.7 years (18-79 years. The clinical signs and symptoms were unspecific and resembled intestinal obstruction. Clinical examination revealed abdominal distension and/or diffuse tenderness with or without signs of peritonitis. The use of CT scans, X-rays or ultrasound did not differ significantly between patients. In 9 of 20 patients that received abdominal CT scans, "whirlpool sign" on the CT scan was present. Secondary small bowel volvulus was present in 58.1% of patients, and causes included bands (3, adhesion (7, congenital anomalies (7 and stromal tumor (1. Out of the 31 patients, 15 with gangrenous small bowel had to undergo intestinal resection. Intestinal gangrene was present with higher neutrophils count (p<0.0001 and the presence of bloody ascites (p = 0.004. Three patients died of septic shock (9.68%, and the recurrence rate was 3.23%.To complete an early and accurate diagnosis, a CT scan plus physical exam seems to be the best plan. After diagnosis, an urgent laparotomy must be performed to avoid intestinal necrosis and perforation. After surgery, more than 90% of the patients can expect to have a favorable prognosis.

    Prenatal small-bowel obstruction can result from single or multiple atresias, and it can be an isolated abnormality or part of a syndrome. It is sometimes the first manifestation of cystic fibrosis. Accurate prediction of the level of obstruction and length of bowel affected can be difficult, presenting a challenge for counseling families and planning perinatal management. To review the prenatal US and MRI findings of small-bowel obstruction and to assess whether fetal MRI adds information that could improve prenatal counseling and perinatal management. We retrospectively reviewed 12 prenatally diagnosed cases of small-bowel obstruction evaluated by both US and MRI from 2005 to 2015. We analyzed gestational age at evaluation, US and MRI findings, gestational age at delivery and postnatal outcomes. The final diagnoses were jejunal atresia (7), ileal atresia (1), cystic fibrosis (3) and combined jejunal and anal atresia (1). Four of the eight with jejunal atresia were found to have multiple small-bowel atresias. Prenatal perforation was noted in three. We identified a trend of increasing complexity of bowel contents corresponding to progressively distal level of obstruction, as indicated by increasing US echogenicity and high T1 signal on MRI. Seven cases of jejunal atresia and one case of ileal atresia demonstrated small ascending, transverse and descending colon (microcolon) with filling of a normal-diameter rectum. In contrast, all three fetuses with cystic fibrosis and the fetus with jejunal-anal atresia demonstrated microcolon as well as abnormal paucity or absence of rectal meconium. Polyhydramnios was present in nine. Eight were delivered prematurely, of whom seven had polyhydramnios. The fetus with jejunal and anal atresia died in utero. Postnatally, three had short gut syndrome, all resulting from multiple jejunal atresias; these three were among a subset of four fetuses whose bowel diameter measured more than 3 cm. Eight infants had no further

    Purpose: We have previously shown that intensity-modulated radiotherapy (IMRT) can reduce dose to small bowel, bladder, and bone marrow compared with three-field conventional radiotherapy (CRT) technique in the treatment of rectal cancer. The purpose of this study was to review our experience using IMRT to treat rectal cancer and report patient clinical outcomes. Methods and Materials: A retrospective review was conducted of patients with rectal cancer who were treated at Mayo Clinic Arizona with pelvic radiotherapy (RT). Data regarding patient and tumor characteristics, treatment, acute toxicity according to the Common Terminology Criteria for Adverse Events v 3.0, tumor response, and perioperative morbidity were collected. Results: From 2004 to August 2009, 92 consecutive patients were treated. Sixty-one (66%) patients were treated with CRT, and 31 (34%) patients were treated with IMRT. All but 2 patients received concurrent chemotherapy. There was no significant difference in median dose (50.4 Gy, CRT; 50 Gy, IMRT), preoperative vs. postoperative treatment, type of concurrent chemotherapy, or history of previous pelvic RT between the CRT and IMRT patient groups. Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced {>=}Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, {>=}Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. Conclusions: In the management of rectal cancer, IMRT is associated with a

    AIM: The aim of this prospective study was to evaluate the overall findings of conventional enteroclysis (CE) with complementary magnetic resonance enteroclysis (MRE) in small bowel disease. METHODS: The study included 32 patients referred from various clinical departments, with known or suspected small bowel disease and abnormalities on CE. Immediately after CE, true fast imaging with steady-state precession (true FISP), and unenhanced and gadolinium-enhanced T1-weighted fast low-angle shot (FLASH) sequences with fat saturation were obtained. Mucosal, mural and luminal changes of the small bowel were evaluated by each technique. In addition, bowel wall thickening, bowel wall enhancement and perienteric changes were assessed by MRE. The radiological findings obtained were evaluated together as a combination, and the role of MRE in the determination of the activity and complications of the small bowel disease was assessed. Radiological findings were correlated with clinical evaluation and follow-up in all cases, including endoscopy in 14 cases and surgery in 5 cases. RESULTS: MRE provided important supplementary mural and extramural information, including degree of pathological wall thickness, mural enhancement pattern associated with disease activity, perivisceral collection, abscess formation, mesenteric fibrofatty proliferation, lymphadenopathy and increase in perienteric vascularity. Short strictures were not revealed on MRE; however, for patients with a history of abdominal malignancy, MRE helped characterize the level of any obstruction and the extent of the disease. CONCLUSION: We recommend MRE for patients who have findings of advanced inflammatory bowel disease or neoplasm on CE examination. The combination of these two techniques can provide important information on the degree and extent of the disorder.

  19. Fecal calprotectin as a biomarker of inflammatory lesions of the small bowel seen by videocapsule endoscopy

    2015-04-01

    Full Text Available Introduction: The levels of calprotectin in the stools are proportional to neutrophil activity in the enteric lumen, so fecal calprotectin is a useful intestinal inflammatory biomarker. It is an extended tool as predictor of colonic pathology but there is scare evidence about its utility in the small bowel. Objective: To test the yield of fecal calprotectin to detect lesions in the small bowel. Material and methods: We have retrospectively included 71 patients sent for small bowel capsule endoscopy in study for suspected inflammatory bowel disease. All of them had a determination of fecal calprotectin and had been sent to colonoscopy with no findings. Patients have been divided in groups: A, fecal calprotectin 100 µg/g, and we have analyzed which of them presented inflammatory lesions in capsule endoscopy studies. Results: The rate of patients with signi ficative lesions was 1 out of 10 (10% in group A, 6 out of 24 (25% in group B, and 21 out of 34 (62% in group C. If we consider levels over 50 µg/g pathologic, fecal calprotectin presents sensitivity: 96%, specificity: 23%, NPV: 90% and PPV: 56%. If we consider levels over 100 µg/g pathologic these values are sensitivity: 75%, specificity: 67%, NPV: 79% and PPV: 62%. Conclusions: Fecal calprotectin has high sensitivity but not so good specificity for predicting small bowel lesions after a normal colonoscopy. In daily practice it will be more useful to establish in 100 µg/g the limit to indicate capsule endoscopy studies.

    Magnetic resonance enterography (MRE) is a relatively new imaging modality that involves small bowel distension with orally administered fluid. Few studies have assessed its impact on patient management. The aim of this study was to determine whether MRE influenced the management of patients with established small bowel Crohn's disease (CD). From a prospectively maintained database of patients with inflammatory bowel disease, we identified patients with small bowel CD who underwent MRE between January 2007 and December 2010. The results of the MRE and subsequent changes in patient management within 1 month were evaluated. Thirty women and 27 men with CD were included. Seven patients (12%) had a normal MRE. Forty-two of 57 (74%) patients had a change in management, and 41/50 (82%) patients with an abnormal MRE had changes in management (Pchange in management as a result of the MRE. Because of its high clinical impact on patient management, MRE should become one of the preferred methods of small bowel evaluation in CD. Specific MRE findings may help to stratify treatment options, however, further work is required to validate this.

    There is evidence for both humans and rats that malnutrition frequently occurs when ethanol is chronically ingested. Small bowel 14 C-labelled glucose absorption was measured with an ex vivo system in which the small bowel of the rat was surgically removed and then arterially perfused with an artificial medium. Glucose absorption for a control group of seven rats was 248 +/- 8 microM/min/gm dry weight of small bowel (mean +/- SEM). This was significantly greater than the value 112 +/- 12 microM/min/gm dry weight (P less than 0.005) for a group of five rats in which a competitive inhibitor of glucose absorption, phlorizin (0.2 mM), was added to the bowel lumen. In the presence of 3% ethanol within the gut lumen of five rats, glucose absorption was also reduced (to 131 +/- 12 microM/min/gm dry weight) compared to absorption in the control group (P less than 0.005). The calculated amount of glucose absorbed was corrected for metabolism to lactate and carbon dioxide. We conclude that both phlorizin and ethanol inhibit glucose absorption in the isolated and perfused small bowel of rats and that probably at least part of the malnutrition in ethanol-fed rats is due to glucose malabsorption

    Small bowel endoscopy with existing endoscopes is limited by problems of discomfort and the technical difficulty of advancing far into the small-bowel. Our aim has been to develop and test wireless capsule endoscopy. Wireless endoscopes, in the form of capsules (11 x 33 mm), were constructed by Given Imaging. These were powered by silver oxide batteries and each contained a CMOS imaging chip and miniature processor, white light emitting diodes (LEDs), a short focal length lens, and a miniature transmitter and antenna. Two video frames per second were transmitted, using radio-frequency (approx. 410 MHz), to an array of aerials attached to the body. The array of aerials can also be used to calculate the position of the capsule in the body. The images were stored on a portable recorder carried on a belt and subsequently downloaded for analysis. The batteries allow more than 5 hours of recording, although the capsule generally passes through the whole small bowel in under two hours. Clear video images of the human bowel were recorded from the pylorus to the caecum. Wireless endoscopy, for the first time, allows painless optical imaging of the whole of the small bowel.

    INTRODUCTION: Small bowel obstruction is a common world-wide condition that has a range of etiological factors. The management is largely dependent on the cause of the obstruction. Small bowel obstruction caused by foreign body ingestion is rare; many items have been reported as responsible, but there are no reports implicating polyurethane foam. CASE PRESENTATION: We report the case of a 44-year-old Irish male who presented following ingestion of polyurethane foam. He was asymptomatic on presentation but developed a small bowel obstruction shortly thereafter. CONCLUSION: Patients presenting following ingestion of polyurethane foam should be scheduled for elective laparotomy, gastrotomy, and retrieval of the cast on the next available theatre list - given that they are suitable for surgery.

    Full Text Available Several radiological and endoscopic techniques are now available for the study of inflammatory bowel diseases. In everyday practice, the choice of the technique to be used depends upon its availability and a careful evaluation of diagnostic accuracy, clinical usefulness, safety, and cost. The recent development of innovative and noninvasive imaging techniques has led to a new and exciting area in the exploration of the gastrointestinal tract, especially in Crohn’s disease patients by using ultrasound with oral or intravenous contrast.

  6. Small-bowel necrosis complicating a cytomegalovirus-induced superior mesenteric vein thrombosis in an immunocompetent patient: a case report

    Science.gov (United States)

    2012-01-01

    Introduction Superior mesenteric venous thrombosis as a result of acute cytomegalovirus infection is rare, with only a few cases reported in the literature. Case presentation We present the case of a 40-year-old Caucasian man who was admitted to our hospital with a 5-day history of fever. His serological test and pp65 antigen detection of cytomegalovirus were positive, suggesting acute infection. On the sixth day after his admission, the patient complained of acute, progressive abdominal pain. Abdominal computed tomography revealed acute superior mesenteric venous thrombosis. An emergency laparotomy showed diffuse edema and ischemic lesions of the small bowel and its associated mesentery with a 50-cm-long segmental infarction of the proximal jejunum. An extensive enterectomy of about 100 cm of jejunum that included the necrotic segment was performed, followed by an end-to-end anastomosis. Anti-coagulation therapy was administered pre-operatively in the form of small-fractionated heparin and continued postoperatively. The patient had an uneventful recovery and was discharged on the 11th postoperative day. Conclusion Acute cytomegalovirus infection can contribute to the occurrence of mesenteric venous thrombosis in immunocompetent patients. It is important for physicians and internists to be aware of the possible thrombotic complications of cytomegalovirus infection. A high level of clinical suspicion is essential to successfully treat a potentially lethal condition such as superior mesenteric venous thrombosis. PMID:22531275

    We describe a rare case of small bowel obstruction and perforation secondary to a primary enterolith in an 84-year-old female patient with jejunal diverticulosis. She underwent an emergency laparotomy, small bowel resection and primary anastomosis. Multiple jejunal diverticula and a large stone were identified at the time of operation. Analysis of the stone demonstrated mainly faecal material consistent with a true primary enterolith. A literature search of Medline and PubMed revealed three cases similar to the one described. The pathogenesis and management of enterolithiasis in jejunal diverticular disease is considered.

    Tevaearai, H; Achtari, C; Suter, M

    1994-12-01

    As a cause of small intestine occlusion, volvulus is often a consequence of a band or adhesions. Except in infants, it is rarely the primary cause of symptomatology. Between January 1976 and December 1992, 13 patients (7 women and 6 men, mean age of 56.8 years) were admitted in our department for an acute abdomen due to a spontaneous primary volvulus of the small bowel. Clinical examination and laboratory tests did not help in preoperative diagnosis. All patients underwent an explorative laparotomy. Six patients had had prior abdominal surgery but none of them presented adhesion or band. In 8 patients (62%), detorsion was sufficient. Resection of a segment of small bowel was necessary in 4 patients. Gangrenous of the entire bowel was observed in one patient who rapidly died. Two patients presented minor complications. One patient with Down syndrome died of bronchoaspiration. One patient has been reoperated on one year later for recurrence of the volvulus, and underwent a Noble procedure. We conclude that volvulus of the small bowel is a rare cause of acute abdomen that must be remembered. Early surgery is mandatory to reduce the risk of gangrene, which is known to double the mortality. Laparoscopy will be helpful in early diagnosis and therapy.

    A new method employing 99mTc-labeled pellets for determination of the gastric emptying rate and small bowel transit time is described. The participants were six normal subjects and 16 patients with irritable bowel syndrome (eight with diarrhea and eight with obstipation as the primary complaint). The gastric emptying rate was the same in the three groups. The patients in the obstipation group had a significantly longer small bowel transit time than the normals (P less than 0.02) and the patients in the diarrhea group (P less than 0.01). There was no demonstrable difference between the small bowel transit time in the normals and in the patients in the diarrhea group.

    Full Text Available Gastrointestinal stromal tumor (GIST is a rare stromal neoplasm, which represents the most common mesenchymal tumor of the gastrointestinal tract. It is characterized by indolent clinical symptoms, although it can present as a life-threatening emergency. Herein, we present two cases of primary small bowel GIST treated at our department. A 68-year-old female patient presented to our emergency department with a diffuse abdominal pain of acute onset. Imaging studies revealed a mass at proximal jejunum, with a nearby free air and fluid. At surgery, a mass of 9 cm was found at proximal jejunum, 3 cm distal to the treitz ligament, with perforation on the lateral wall of the mass. En bloc resection was performed. Pathology report was positive for gastrointestinal stromal tumor. A 70-year-old male patient presented to our emergency department with 3 days of dark tarry stool and few hours of hematochezia. Computed tomography angiography revealed a mass at the pelvis, with calcifications, attached to the distal ileum, with intraluminal blush of intravenous iodine. At surgery, a mass of 8 cm at the distal ileum was found. Resection of the mass along with a 20 cm of ileum was completed. Histopathology report was positive for malignant gastrointestinal stromal tumor.

    Physicians often diagnose diverticulitis and prescribe antibiotics in outpatients with abdominal pain and tenderness without other evidence. We investigated the misattribution of irritable bowel syndrome (IBS) symptoms to diverticulitis in outpatients. In patients diagnosed with diverticulitis and dispensed antibiotics in an integrated healthcare system, we retrospectively compared 15,846 outpatients managed without computed tomography (CT) versus 3750 emergency department/inpatients who had CT. We assessed demographics and past history, including 17 symptom-based somatic and 11 mental disorders and three somatic-mental comorbidity pairs (dyads) coded over 3 years and seven drug classes dispensed over 1 year before diagnosis. Univariate analysis showed small intergroup demographic differences. Outpatients had increases in prior diverticulitis, including outpatient-managed episodes, total somatic diagnoses (p diverticulitis history, IBS, chest pain, dyspepsia, fibromyalgia, low back pain, migraine, acute reaction to stress, and antispasmodic and anxiolytic dispensing and negatively associated with non-dependent drug abuse and opioid dispensing (p ≤ .0226). Multiple types of indirect and concordant evidence suggest misattribution of IBS pain to diverticulitis and unnecessary antibiotic therapy in outpatients.

    2009-01-01

    In evaluating the long-term intensive treatments essential for short bowel syndrome, we analyzed 10 cases of acute superior mesenteric arterial (SMA) occlusion. Abdominal CT scan detected a smaller superior mesenteric vein (SMV) sign in five out of seven cases, which was useful in making preoperative diagnosis even in noncontrast-enhanced CT. The greater part of the small intestine and part of the colon which became necrotic were resected in all 10 cases. Six patients who were able to be eventually discharged from the hospital had a mean residual jejunum length of 75 cm. Four patients requiring no parenteral nutrition had a mean intestinal length of 95 cm, compared to 35 cm for the two still requiring parenteral nutrition. We report here a case of a 68-year-old man with a 20-cm residual jejunum after surgery for SMA occlusion. He has been unable to eat orally and requiring total parenteral home nutrition, and suffered from catheter infection requiring 24 catheter replacements. Despite survival exceeding for more than 5 years, longer than that of reported cases so far, his quality of life is not necessarily good. (author)

  15. The Accuracy of Point-of-Care Ultrasound in Detecting Small Bowel Obstruction in Emergency Department

    2018-01-01

    Full Text Available Radiological imaging plays an essential role in the evaluation of a patient with suspected small bowel obstruction (SBO. In a few studies, point-of-care ultrasound (POCUS has been utilized as a primary imaging modality in patients with suspected SBO. POCUS has been shown to be an accurate tool in the diagnosis of SBO with multiple research studies noting a consistent high sensitivity with a range of 94–100% and specificity of 81–100%. Specific sonographic findings that increase the likelihood of SBO include dilatation of small bowel loops > 25 mm, altered intestinal peristalsis, increased thickness of the bowel wall, and intraperitoneal fluid accumulation. Studies also reported that emergency physicians could apply this technique with limited and short-term ultrasound training. In this article, we aim to review the sensitivity and specificity of ultrasound examinations performed by emergency physicians in patients with suspected SBO.

    Small bowel cancer is frequently detected at an advanced stage and its prognosis is poor. We report on a patient with small bowel cancer with positive peritoneal cytology who survived for 5 years without recurrence after surgery.The case involved a 73-year-old woman who had undergone partial resection of the small intestine and lymphadenectomy for a small bowel tumor with obstruction. Pathological examination confirmed papillary adenocarcinoma with partial serosal invasion. Ascites cytology indicated a class V tumor. Adjuvant chemotherapy with TS-1 was administered for 20 months, and the patient has survived without evidence of disease for over 5 years.In this case, it is possible that TS-1 chemotherapy was effective for prevention against small bowel cancer recurrence.Furthermore , peritoneal cytology in patients with small bowel cancer should be evaluated as a predictor of prognosis.

  17. Proton pump inhibitor therapy did not increase the prevalence of small-bowel injury: A propensity-matched analysis.

    Full Text Available Previous studies have reported that the suppression of acid secretion by using proton pump inhibitors (PPIs results in dysbiosis of the small-bowel microbiota, leading to exacerbated small-bowel injuries, including erosions and ulcers. This study was designed to assess the association between PPI therapy and small-bowel lesions after adjustment for the differences in baseline characteristics between users and non-users of PPIs.We retrospectively studied patients suspected to be suffering from small-bowel diseases, who underwent capsule endoscopy between 2010 and 2013. We used propensity matching to adjust for the differences in baseline characteristics between users and non-users of PPIs. The outcomes included the prevalence of small-bowel lesions: erosion, ulcer, angioectasia, varices, and tumor.We selected 327 patient pairs for analysis after propensity matching, and found no significant differences in the prevalence of small-bowel injuries, including erosions and ulcers, between users and non-users of PPIs. Two subgroup analyses of the effect of the type of PPI and the effect of PPI therapy in users and non-users of nonsteroidal anti-inflammatory drugs indicated no significant differences in the prevalence of small-bowel injuries in these two groups.PPI therapy did not increase the prevalence of small-bowel injury, regardless of the type of PPI used and the use of nonsteroidal anti-inflammatory drugs.

    Computed tomography (CT) as a fast and reliable diagnostic technique is the imaging modality of choice for acute bowel ischemia. However, diagnostic is often difficult mainly due to low attenuation differences between ischemic and perfused segments. To compare the diagnostic efficacy of a new post-processing tool based on frequency selective non-linear blending with that of conventional linear contrast-enhanced CT (CECT) image blending for the detection of bowel ischemia. Twenty-seven consecutive patients (19 women; mean age = 73.7 years, age range = 50-94 years) with acute bowel ischemia were scanned using multidetector CT (120 kV; 100-200 mAs). Pre-contrast and portal venous scans (65-70 s delay) were acquired. All patients underwent surgery for acute bowel ischemia and intraoperative diagnosis as well as histologic evaluation of explanted bowel segments was considered "gold standard." First, two radiologists read the conventional CECT images in which linear blending was adapted for optimal contrast, and second (three weeks later) the frequency selective non-linear blending (F-NLB) image. Attenuation values were compared, both in the involved and non-involved bowel segments creating ratios between unenhanced and CECT. The mean attenuation difference between ischemic and non-ischemic wall in the portal venous scan was 69.54 HU (reader 2 = 69.01 HU) higher for F-NLB compared with conventional CECT. Also, the attenuation ratio between contrast-enhanced and pre-contrast CT data for the non-ischemic walls showed significantly higher values for the F-NLB image (CECT: reader 1 = 2.11 (reader 2 = 3.36), F-NLB: reader 1 = 4.46 (reader 2 = 4.98)]. Sensitivity in detecting ischemic areas increased significantly for both readers using F-NLB (CECT: reader 1/2 = 53%/65% versus F-NLB: reader 1/2 = 62%/75%). Frequency selective non-linear blending improves detection of bowel ischemia compared with conventional CECT by increasing

    Aim: To investigate the frequency, clinical significance, and outcome of small-bowel intussusceptions in adults detected using ultrasound in an outpatient setting. Patients and methods: In two different retrospective (January 2001 to April 2003) and prospective (May 2003 to June 2005) periods, 33 small-bowel intussusceptions were found in 32 patients (13 females; mean age: 38.1 years) with known or suspected intestinal disease. Patients underwent diagnostic work-up to assess any organic disease. Patients with self-limiting intussusception were submitted to clinical and ultrasonographic follow-up. Results: Of the 32 patients with small-bowel intussusception, 25 were identified in the prospective series of 4487 examinations (0.53%) and seven in the retrospective series of 5342 examinations (0.15%; p = 0.002). Four patients had persistent and 28 self-limiting intussusceptions. Self-limiting intussusceptions were idiopathic in 11 patients (39%) or associated with organic diseases in 17 (Crohn's disease in 11 patients, celiac disease in three, ulcerative colitis in one patient, and previous surgery for cancer in two). Self-limiting intussusceptions were asymptomatic in 25% of patients. Conclusion: Small-bowel intussusceptions in adults are not rare and are frequently self-limiting, idiopathic, or related to organic diseases, mainly Crohn's disease and coeliac disease.

    Full Text Available The incidence of chronic diarrhea in Asia is between 0.8-1.0%. The diseases and abnormalities according to the location, which can cause chronic diarrhea, are divided into three locations: the small bowel, the large bowel and extraintestinal. The small bowel diseases include infectious and non-infectious diseases. The infectious diseases are bacterial infections, parasitic infections etc. The non-infectious diseases include of Crohn’s disease, Celiac sprue, NSAID enteropathy, lactose intolerance, benign tumor, carcinoid tumor, carcinoma, post surgery complications, laxative etc. The approaches to diagnosis include good anamnesis, careful physical examination, supporting laboratory tests, more specialized supporting examinations including X-ray of the colon, esophagogastroduodenum follow-through, enteroclysis, ileo-colonoscopy and endoscopy on the upper portion of the digestive tract including the small intestine with biopsy for histopathology examinations. The treatment for chronic diarrhea is divided into supportive and causal therapy. (Med J Indones 2002; 11: 179-89 Keywords: small bowel, chronic diarrhea, approaches to diagnosis, treatment

    Portal venous drainage of small bowel grafts is theoretically more physiologic than systemic drainage, but is technically more demanding. Comparisons in animal models have not demonstrated a clear advantage of one technique over the other, but clinical data are lacking. Clinical records of 36 patients who underwent 37 small bowel transplantation procedures from January 1995 to August 2001 were reviewed. Portal drainage was performed in 19 patients (PD group). Systemic drainage was performed in 18 patients (SD group). Median followup was 531 days. PD and SD patients had similar ICU stays (median 7 versus 9 days) and endotracheal intubation durations (median 3 versus 5 days). All current survivors, with the exception of one patient in each group, are independent from parenteral nutrition. Liver function tests were similar in both groups. There was a twofold increase in tacrolimus dosage in the PD group to achieve similar trough levels indicating a "first-pass" hepatic clearance effect. Cumulative incidence of acute rejection episodes and OKT3-requiring rejection episodes were similar in both groups. To the contrary, a lower incidence of gram-negative rods of Enterococcus sp. in blood or bronchoalveolar lavage suggested that the clearance of translocated intestinal bacteria was more efficient in the PD group. Graft and patient survival rates were similar in both groups. Systemic venous drainage of small bowel transplants is a dependable technique, associated with similar results as portal venous drainage, in terms of overall mortality, morbidity, rejection, function, and patient and graft survival. But attention should be paid to an impaired clearance of intestinal bacterial translocation after systemic drainage.

    Gut ischemia has been implicated in the pathogenesis of necrotizing enterocolitis. Cyclosporine A and rapamycin, both potent novel immunosuppressants which act on signal transduction pathways in CD4+ T-cells, could potentially modulate immune/inflammatory cellular reactions involved in tissue ischemia/reperfusion injury. We hypothesized that cyclosporine A and rapamycin would preserve mucosal cell function and attenuate inflammatory T-cell-mediated cellular changes associated with small bowel ischemic injury. Forty Sprague-Dawley rats underwent 60 min of gut ischemia by vascular occlusion of the superior mesenteric vessels. Animals were randomized to four groups (n = 10): cyclosporine A (CSA, 5 mg/kg/day SQ), rapamycin (RAP, 2 mg/kg/day SQ), cyclosporine A and rapamycin (C&R), and vehicle given to controls (CON). Following 1 hr of reperfusion, small bowel was harvested for xanthine oxidase (XO, units/mg protein) and maltase (MALT, mM substrate degraded/min/g protein) assays. Blood was obtained from the portal vein for tumor necrosis factor-alpha (TNF-alpha, pg/ml) assay. The results of the study are presented below (mean +/- SEM, *, P < 0.05 versus controls). (Table in text) The results indicate that cyclosporine and rapamycin each play a significant role in attenuating ischemia/reperfusion injury in the gut. These data suggest that there are cytoprotective and anti-inflammatory mechanisms of these drugs independent of T-cell signal transduction that provide some protective effect in small bowel ischemia. Furthermore, T-cell-mediated immune mechanisms may not be associated with the adverse effects of small bowel ischemia/reperfusion injury. Additional investigation will be necessary in order to define the role of T-cell-mediated immune injury in the gut and how this relates to the beneficial effect of immunosuppression in small bowel mucosal ischemic injury.

    AIM: To study the therapeutic efficacy of a new transnasal ileus tube advanced endoscopically for adhesive small bowel obstruction. METHODS: A total of 186 patients with adhesive small bowel obstruction treated from September 2007 to February 2011 were enrolled into this prospective randomized controlled study. The endoscopically advanced new ileus tube was used for gastrointestinal decompression in 96 patients and ordinary nasogastric tube (NGT) was used in 90 patients. The therapeutic efficacy was compared between the two groups. RESULTS: Compared with the NGT group, the ileus tube group experienced significantly shorter time for relief of clinical symptoms and improvement in the findings of abdominal radiograph (4.1 ± 2.3 d vs 8.5 ± 5.0 d) and laboratory tests (P tube group and 46.7% in the NGT group (P tube group and 53.3% of the NGT group underwent surgery. For recurrent adhesive bowel obstruction, ileus tube was also significantly more effective than NGT (95.8% vs 31.6%). In the ileus tube group, the drainage output on the first day and the length of hospital stay were significantly different depending on the treatment success or failure (P tube can be used for adhesive small bowel obstruction. Endoscopic placement of the ileus tube is convenient and worthy to be promoted despite the potential risks. PMID:22563179

    Pericecal hernia is a rare type of internal hernia and, though congenital in origin, may occur at any age, usually with symptoms of acute intestinal obstruction. The pathophysiology and character of these defects are described, and the management of this situation in an 80-year-old patient is reported. Prompt operative intervention to avoid the associated high mortality secondary to strangulation is urged. It is suggested that closure of these defects be performed if incidentally found at laparotomy.

    Full Text Available Introduction: The purpose of our study was to describe the evaluation and outcome of patients with ileus and bowel obstruction admitted to an emergency department (ED observation unit (OU and to identify predictors of successful management for such patients. Methods: We performed a retrospective chart review of 129 patients admitted to a university-affiliated, urban, tertiary hospital ED OU from January 1999 through November 2004. Inclusion criteria were all adult patients admitted to the OU with an ED diagnosis of ileus, partial small bowel obstruction, or small bowel obstruction, and electronic medical records available for review. The following variables were examined: ED diagnosis, history of similar admission, number of prior abdominal surgeries, surgery in the month before, administration of opioid analgesia at any time after presentation, radiographs demonstrating air–fluid levels or dilated loops of small bowel, hypokalemia, use of nasogastric decompression, and surgical consultation. Results: Treatment failure, defined as hospital admission from the OU, occurred in 65 (50.4% of 129 patients. Only the use of a nasogastric tube was associated with OU failure (21% discharged versus 79% requiring admission, P ¼ 0.0004; odds ratio, 5.294; confidence interval, 1.982–14.14. Conclusion: Half of the patients admitted to our ED OU with ileus or varying degrees of small bowel obstruction required hospital admission. The requirement of a nasogastric tube in such patients was associated with a greater rate of observation unit failure. [West J Emerg Med. 2011;12(4:404–407.

    Intestinal atresia has still significant morbidity in developing countries. Stomas are now not recommended in every case of intestinal atresia; primary anastomosis is the goal of surgery after resection of dilated adynamic gut. A new type of stoma formation along with primary anastomosis is being presented here. This report is based on our experience of many cases with this technique in last 12 years but all the details and long follow-up of each case is not available. However the method of surgical procedure, progress, complications, and advantages encountered have been highlighted. Presently we have data of 7 patients; others are lost to follow up. Three had died with other associated problems, namely one with multiple atresias, two with septic shock and prematurity. Two stomas did not require formal closure because stoma shriveled and disappeared. Two other stomas had grown very long like a diverticulum when these were closed after 5 and 8 months. This technique is another attempt to decrease morbidity of patients of intestinal atresia especially in those cases where short bowel syndrome is feared after resection of proximal dilated gut.

    Purpose: We have previously shown that intensity-modulated radiotherapy (IMRT) can reduce dose to small bowel, bladder, and bone marrow compared with three-field conventional radiotherapy (CRT) technique in the treatment of rectal cancer. The purpose of this study was to review our experience using IMRT to treat rectal cancer and report patient clinical outcomes. Methods and Materials: A retrospective review was conducted of patients with rectal cancer who were treated at Mayo Clinic Arizona with pelvic radiotherapy (RT). Data regarding patient and tumor characteristics, treatment, acute toxicity according to the Common Terminology Criteria for Adverse Events v 3.0, tumor response, and perioperative morbidity were collected. Results: From 2004 to August 2009, 92 consecutive patients were treated. Sixty-one (66%) patients were treated with CRT, and 31 (34%) patients were treated with IMRT. All but 2 patients received concurrent chemotherapy. There was no significant difference in median dose (50.4 Gy, CRT; 50 Gy, IMRT), preoperative vs. postoperative treatment, type of concurrent chemotherapy, or history of previous pelvic RT between the CRT and IMRT patient groups. Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced ≥Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, ≥Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. Conclusions: In the management of rectal cancer, IMRT is associated with a

Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced ≥Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, ≥Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. In the management of rectal cancer, IMRT is associated with a clinically significant reduction in lower GI toxicity

    MR and CT techniques optimized for small bowel imaging are playing an increasing role in the evaluation of small bowel disorders. Several studies have shown the advantage of these techniques over tradition barium fluoroscopic examinations secondary to improvements in spatial and temporal resolution combined with improved bowel distending agents. The preference of MR vs. CT has been geographical and based on expertise and public policy. With the increasing awareness of radiation exposure, there has been a more global interest in implementing techniques that either reduce or eliminate radiation exposure [Brenner DJ, Hall EJ. Computed tomography-an increasing source of radiation exposure. N Engl J Med 2007;357:2277-84]. This is especially important in patients with chronic diseases such as inflammatory bowel disease who may require multiple studies over a lifetime or in studies that require sequential imaging time points such as in assessment of gastrointestinal motility [Froehlich JM, Patak MA, von Weymarn C, Juli CF, Zollikofer CL, Wentz KU. Small bowel motility assessment with magnetic resonance imaging. J Magn Reson Imaging 2005;21:370-75]. A recent study showed that certain subgroups of patients with Crohn's disease may be exposed to higher doses of radiation; those diagnosed at an early age, those with upper tract inflammation, penetrating disease, requirement of intravenous steroids, infliximab or multiple surgeries [Desmond AN, O'Regan K, Curran C, et al. Crohn's disease: factors associated with exposure to high levels of diagnostic radiation. Gut 2008;57:1524-29]. Therefore it has been suggested that techniques that can reduce or eliminate radiation exposure should be considered for imaging [Brenner DJ, Hall EJ. Computed tomography-an increasing source of radiation exposure. N Engl J Med 2007;357:2277-84]. Owing to the excellent softtissue contrast, direct multiplanar imaging capabilities, new ultrafast breath-holding pulse sequences, lack of

    Stagnant or blind-loop syndrome includes vitamin B12 malabsorption, steatorrhea, and bacterial overgrowth of the small intestine. A case is presented to demonstrate this syndrome occurring after small-bowel irradiation injury with exaggeration postenterocolic by-pass. Alteration of normal small-bowel flora is basic to development of the stagnant-loop syndrome. Certain strains of bacteria as Bacteriodes and E. coli are capable of producing a malabsorption state. Definitive therapy for this syndrome developing after severe irradiation injury and intestinal by-pass includes antibiotics. Rapid symptomatic relief from diarrhea and improved malabsorption studies usually follow appropriate antibiotic therapy. Recolonization of the loop(s) with the offending bacterial species may produce exacerbation of symptoms. Since antibiotics are effective, recognition of this syndrome is important. Foul diarrheal stools should not be considered a necessary consequence of irradiation injury and intestinal by-pass

    The diagnostic accuracy of multidetector row computed tomography for the prospective diagnosis of acute bowel ischemia in the daily clinical routine was analyzed. Two hundred ninety-one consecutive patients with an acute or subacute abdomen, examined by MDCT over a time period of 5 months, were included in the study. All original CT diagnoses made during the daily routine by radiological generalists were compared to the final diagnoses made by using all available medical information from endoscopies, surgical interventions, autopsies and follow-up. Finally, all CT examinations of patients with an initial CT diagnosis or a final diagnosis of bowel ischemia were reread by a radiologist specialized in abdominal imaging in order to analyze the CT findings and the reasons for initially false negative or false positive CT readings. Twenty-four patients out of 291 (8.2%) had acute bowel ischemia. The age of affected patients ranged from 50 to 94 years (mean age: 75.7 years). Eleven patients were male, and 13 female. Reasons for acute bowel ischemia were: arterio-occlusive (n=11), non-occlusive (n=5), strangulation (n=2), over-distension (n=3) and radiation (n=3). The prospective sensitivity, specificity, PPV and NPV of MDCT for the diagnosis of acute bowel ischemia in the daily routine were 79.17, 98.51, 90.48 and 98.15%. MDCT reaches a similarly high sensitivity in diagnosing acute bowel as angiography. Furthermore, it has the advantage of being helpful in most of its clinical differential diagnoses and of being less invasive with the consecutive possibility of being used earlier in the diagnostic process with all the resulting positive effects on the patients prognosis. Therefore, nowadays MDCT should probably be used as the first step imaging modality of choice in patients with suspected acute bowel ischemia. (orig.)

    Annually, 15% of practicing general surgeons face a malpractice claim. Small bowel obstruction accounts for 12-16% of all surgical admissions. Our objective was to analyze malpractice related to small bowel obstruction. Using the search terms "medical malpractice" and "small bowel obstruction," we searched through all jury verdicts and settlements for Westlaw. Information was collected on case demographics, alleged reasons for malpractice, and case outcomes. The search criteria yielded 359 initial case briefs; 156 met inclusion criteria. The most common reason for litigation was failure to diagnose and timely manage the small bowel obstruction (69%, n = 107). Overall, 54% (n = 84) of cases were decided in favor of the defendant (physician). Mortality was noted in 61% (n = 96) of cases. Eighty-six percent (42/49) of cases litigated as a result of failing to diagnose and manage the small bowel obstruction in a timely manner, resulting in patient mortality, had a verdict with an award payout for the plaintiff (patient). The median award payout was $1,136,220 (range, $29,575-$12,535,000). A majority of malpractice cases were decided in favor of the defendants; however, cases with an award payout were costly. Timely intervention may prevent a substantial number of medical malpractice lawsuits in small bowel obstruction, arguing in favor of small bowel obstruction management protocols.

    Obscure small-bowel disorders are jejunal and ileal lesions undiagnosed by traditional imaging techniques (endoscopic, radiologic). We evaluated the diagnostic usefulness and safety of capsule endoscopy for obscure small-bowel disorders in children and adolescents. Comparative, prospective, self-controlled trials in patients (age, 10-18 y) suspected to have either small-bowel Crohn's disease, polyps, or obscure gastrointestinal (GI) bleeding. Capsule results were compared with the diagnostic imaging studies normally used in this age group. Among 20 patients suspected of Crohn's disease, multiple lesions consistent with this diagnosis were observed by capsule endoscopy in 50%. Small-bowel Crohn's disease was ruled out in 8 patients. Eosinophilic enteropathy was found in 2 others. For polyp detection (n = 6), capsule endoscopy yielded 100% concordance with the control studies when analyzed per patient. However, capsule endoscopy revealed a greater number (50%) of polyps. Among patients with obscure bleeding (n = 4), the capsule examination confirmed a diagnosis of vascular malformations in 3. Capsule endoscopy more accurately identified the precise source of bleeding compared with angiography. All 30 capsule studies were well tolerated, although 1 capsule was retained owing to an inflammatory stenosis. The capsule eventually was expelled after corticosteroid therapy. Capsule endoscopy correctly diagnosed or excluded a bleeding source, small-bowel polyps, or Crohn's disease of the small bowel in 29 of 30 patients. Capsule endoscopy permits an accurate, noninvasive approach for diagnosing obscure small bowel lesions in children over the age of 10.

    Inflammatory fibroid polyp is a benign and non-neoplastic condition of the intestinal tract, commonly affecting the gastric antrum, though it can affect any part of the gastro-intestinal tract. It is a submucosal, sessile, poypoid mass composed of myofibroblast like mesenchymal cells, numerous small blood vessels and marked inflammatory cell infiltrate mainly eosinophils. It commonly presents as intestinal obstruction or intussusception. A case of recurrent partial small intestinal obstruction due to intermittent intussusception associated with inflammatory fibroid polyp of jejunum is being reported.

    Confocal endomicroscopy can be used to image intestinal mucosa. Epithelial gaps resulting from shedding of epithelial cells have been reported in patients. We hypothesize that the rate of epithelial cell shedding increases in patients with Crohn's disease, leading to more epithelial gaps and barrier dysfunction. In this study, we used probe-based confocal laser endomicroscopy to quantify epithelial cells and gaps in patients with Crohn's disease compared with controls. We also determined the density of epithelial gaps in a mouse model of inflammatory bowel disease-interleukin-10-deficient (IL-10) mice, versus the background strain using rigid probe confocal endomicroscopy. Probe-based confocal laser endomicroscopy of the terminal ileum of both patients with Crohn's disease and controls was performed by a single endoscopist during colonoscopy. In mice, sections of the small intestine were imaged using a rigid confocal probe. Gap density was defined as the number of epithelial gaps per 1000 cells counted. In this study, we examined 6 controls (2 male and 4 female; median age 59 y) and 8 patients with Crohn's disease (5 male and 3 female; median age 42 y). The mean gap densities (±standard error) observed for the 2 groups were 17.7±5.6 and 117±33 gaps per 1000 cells, respectively (P<0.01). For control and IL-10 mice, the gap densities were 10.5±2.2 and 17.8±1.4 gaps per 1000 cells, respectively (P<0.01). The epithelial gap density was significantly higher in patients with Crohn's disease than controls. Gap density was also elevated in the mouse model of inflammatory bowel disease.

    Small-bowel cancer is uncommon and, accordingly, little is known about the epidemiology of this malignancy, especially by race and subtype. The objective of this analysis was to describe the distribution of small-bowel cancer in the United States by demographic, pathological, and clinical features. This study was retrospective in design. Data from 26 population-based cancer registries in the United States from 1995 to 2008 were used. Patients diagnosed with small-bowel cancer (topography codes C17.0-17.3 and C17.8-17.9) were included. The primary outcomes measured were race- and histology-specific incidence (age-adjusted rate trends and age-specific rates) of small-bowel cancer. A total of 56,223 men and women diagnosed with small-bowel cancer were identified. The overall age-adjusted incidence rates for small-bowel cancer were 26.1 in men and 17.7 in women. Neuroendocrine tumors were the most common histological types of small-bowel cancer in men and women, followed by carcinoma, lymphoma, and sarcoma. In comparison with whites, the rate of small-bowel cancer was 42% greater in black men, 46% greater in black women, 34% lower in Asian-Pacific Islander men, and 37% lower in Asian-Pacific Islander women. Rates of small-bowel cancer were 24% lower in Hispanic men and 15% lower in Hispanic women than rates in non-Hispanics. The excess of small-bowel cancer in blacks and the deficit in Asian-Pacific Islanders were attributable mainly to the incidence of adenocarcinoma and carcinoid tumors. The incidence of GI stromal tumor was significantly higher among Asian-Pacific Islanders. This is one of the largest studies of small-bowel cancer to date. These cancer registry data showed substantial racial and ethnic variation in the incidence of histological subtypes of small-bowel malignancy that suggest possible etiologic diversity and/or disparities in detection.

    The enteric absorption of oxalic acid was determined with 14 C-oxalic acid in patients with small bowel resection, jejunoileal bypass, Crohn's disease and chronic pancreatitis in comparison to the control group. Extreme hyperoxaluria was found in small bowel resections above 100 cm, after bypass operations and in ileocolitis Crohn with signs of clinical activity. Small bowel resections and relapses of Crohn's disease increase the absorption of oxalic acid. The significance of 14 C-oxalic acid absorption test is the recognition of enteric hyperoxaluria.

    Study of the molecular and cellular biology of the small-intestinal mucosa is providing insights into the remarkable properties of this unique tissue. With its structured pattern of cell proliferation, differentiation, and apoptosis, and its ability to adapt following exposure to luminal nutrients or injury from surgery or pathogens, it functions in a regulated but responsive manner. We review recent publications on factors affecting development, gene expression, cell turnover, and adaptation.

    The pathological change of small bowel is difficult to examine because it is anatomically unique. The development of wireless capsule endoscopy provides an unique opportunity to visualize the entire small bowel in a minimally invasive manner. The aim of this study was to assess the safety and clinical value of wireless capsule endoscopy in children. During the last 4 years (June, 2004-June, 2008), 46 times of wireless capsule endoscopy were performed in 43 patients with suspected small bowel disease, including obscure gastrointestinal bleeding (n = 11), recurrent abdominal pain (n = 20), chronic diarrhea (n = 9), protein losing enteropathy (n = 2), recurrent vomiting (n = 1). Of the 43 cases, 28 were male and 15 were female, the age ranged from 6 to 18 years, 8 of these cases were capsule passing through the stomach and the small intestine, the tolerance to and complication of wireless capsule endoscopy in patients, the image quality of capsule endoscopy, and the cleanliness of small intestine after fasting for 8 hours were observed and recorded. All the patients could easily swallow the capsule and had good tolerance. The overall success rate was 94% (43/46). The median time of capsule passing through the stomach and small intestine was 73 min (range, 3 - 600 min) and 246 min (range, 73 - 413 min), respectively. The diagnostic yield of pathological change in small intestine was 90% (37/41), and the diagnostic accordance rate was 84% (31/37). Based on the wireless capsule endoscopy, diagnostic findings included Crohn's diseases (15), lymph follicular hyperplasia (4), nonspecific enteritis (4), vascular malformations (3), small bowel tumour (2), primary intestinal lymphangiectasia (2), gastrointestinal motility disorders (2), Meckel's diverticulum (1), angioma (1), small intestinal worm disease (1), duodenal ulcer (1), and polyposis syndromes (1). The capsule of 1 patient remained in the stomach. The cleanliness of small intestine after 8 hours fasting was good. And

    Full Text Available The authors report a case of spontaneous transmesenteric hernia with strangulation in an adult. Transmesenteric hernia (TMH is a rare cause of small bowel obstruction and is seldom diagnosed preoperatively, and most TMHs in adults are related to predisposing factors, such as previous surgery, abdominal trauma, and peritonitis. TMH are more likely to develop volvulus and strangulation or ischemia. A brief review of etiology, clinical features, diagnosis, and treatment is discussed.

    Small bowel adenocarcinoma (SBA) is a rare but increasing cause of gastrointestinal malignancy, being both a diagnostic and therapeutic challenge. The goal of treatment is margin negative resection of a lesion and local lymphadenectomy, followed by modern adjuvant chemotherapy combinations in selected cases. Improved outcomes in patients with SBA are encouraging, but elucidation of mechanisms of carcinogenesis and risk factors as well as improved treatment for this malignancy is very needed.

    To describe GVHR in small bowel transplantation and its underlying mechanisms and to find methods for circumventing that response, accessory small bowel transplantation was carried out in the rat model. Animals not treated with cyclosporine, irradiation, or removal of the mesenteric lymph nodes of the graft died within 22 days postoperatively due to graft versus host disease. Mesenteric lymph nodes of the graft and recipient spleen and peripheral lymph nodes showed strong immunologic stimulation histologically and high antihost T-cell-mediated cytotoxic antihost reactivity. Seventy-one percent of the animals that had received 15 mg of cyclosporine per kilogram body weight orally survived 150 days after transplantation. After donor irradiation with 50 rads, 77 percent of the recipients survived 120 days. After microsurgical removal of the mesenteric lymph nodes of the graft, 89 percent survived 120 days. We conclude that GVHR plays an important role in small bowel transplantation and that the experimental regimens of donor, graft, and recipient treatment described herein have proved their efficacy for circumventing GVHR

  15. Spontaneous sublingual and intramural small-bowel hematoma in a patient on oral anticoagulation

    2012-08-01

    Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

    To validate a software prototype allowing for small bowel motility analysis in free breathing by comparing it to manual measurements. In all, 25 patients (15 male, 10 female; mean age 39 years) were included in this Institutional Review Board-approved, retrospective study. Magnetic resonance imaging (MRI) was performed on a 1.5T system after standardized preparation acquiring motility sequences in free breathing over 69-84 seconds. Small bowel motility was analyzed manually and with the software. Functional parameters, measurement time, and reproducibility were compared using the coefficient of variance and paired Student's t-test. Correlation was analyzed using Pearson's correlation coefficient and linear regression. The 25 segments were analyzed twice both by hand and using the software with automatic breathing correction. All assessed parameters significantly correlated between the methods (P software (3.90%, standard deviation [SD] ± 5.69) than manual examinations (9.77%, SD ± 11.08). The time needed was significantly less (P software (4.52 minutes, SD ± 1.58) compared to manual measurement, lasting 17.48 minutes for manual (SD ± 1.75 minutes). The use of the software proves reliable and faster small bowel motility measurements in free-breathing MRI compared to manual analyses. The new technique allows for analyses of prolonged sequences acquired in free breathing, improving the informative value of the examinations by amplifying the evaluable data.

    The aim of this study was to evaluate the accuracy of enteroclysis in the diagnosis of Crohn's disease of the small bowel in a group of consecutive patients. From January 1992 to December 1995, 165 patients with suspected Crohn's disease of the small bowel presented to our institution for enteroclysis. In 14 patients up to three enteroclysis exams were performed. Most patients (78 %) underwent colonoscopy and retrograde ileoscopy. In the remaining patients clinical follow-up was used as gold standard. In 79 patients no radiographic abnormalities were found. Sixty-one patients (40 men and 21 women; mean age 34.2 years) had a radiological diagnosis of Crohn's disease. This involved the terminal ileum in 39 patients (64 %) either alone (n = 25) or in association with the pelvic ileum (n = 14). In 12 of these patients retrograde ileoscopy was not feasible. Twenty-one patients underwent surgery. In 4 patients pathology revealed diseases other than Crohn's. These patients had all ileocecal diseases (tuberculosis = 2; non-Hodgkin's lymphoma = 1; adenocarcinoma = 1). One false-negative result was observed. Overall, enteroclysis showed a sensitivity of 98.2 % and a positive predictive value of 93.4 %. Enteroclysis is a sensitive technique in evaluating both the extent and the severity of small bowel involvement in Crohn's disease, although the overlap of radiographic findings may hamper its accuracy when the disease is confined to the ileocecal area.

  20. An experimental study on radiological examination of obstructed small bowel with various contrast media

    1991-01-01

    For the evaluation of the level and cause of small bowel obstruction, an oral barium study is usually chosen. When perforation is whether barium or a water-soluble contrast agent should be used, because barium causes from foreign body reactions as well as adhesions in the extraluminal tissues. Water-soluble contrast agent, on the other hand, are less satisfactory but in general have no untoward effects in the extraluminal tissues. Because of hyperosomolarity, water-soluble contrast agents attract large amounts of fluid with subsequent dilution and loss of contrast and pose a risk of pulmonary edema if aspirated. The use of the newer non-ionic and low-osmolarity water-soluble contrast will likely avoid pulmonary complications due to aspiration. The author performed this experimental study to compare the radiological efficacy of different contrast media in enteric follow-through examinations of obstructed small bowel. Rate had a ligature applied to the distal ileum via laparotomy. Four contrast media were subjected to testing by instillation via oro-gastric tube immediately after laparotomy. Radiographs were exposed at 1, 4 and 8 hours and evaluated later. After 24 hours the animals were sacrificed and the stomach and small bowels, free from mesentery and omental tissue, were weighted with contrasts. The progression in the bowel was proportionate to the osmolarity of the contrast media. After 1 hour, the observations indicated sodium diatrizoate (Gastrografin, Schering) to be the least favorable medium with respect to sharpness of the mucosal border. After 8 hours, barium gave a poorer delineation compared to Ioxaglate (Hexabric, Guerbet) and Iopromide (Ultravist, Schering). Early deaths were noted in the sodium diatrizoate and ioxaglate groups. So we conclude that when using a rather high-volume bolus, low-osmolar non-ionic contrast media seem to have significant prospects for general diagnostic use in patients with suspected intestinal obstruction

    The purpose of this study was to determine the optimal scanning technique for lesion detection in a small bowel phantom and to evaluate the virtual endoscopy (VE) technique in patients. A small bowel phantom with a fold thickness of 7 mm and length of 115 cm was prepared with nine round lesions (3 x 1 mm, 2 x 2 mm, 2 x 3 mm, 2 x 4 mm). Spiral CT parameters were 7/7/4, 3/5/2, 3/5/1, 1.5/3/1 (slice thickness/table feed/reconstruction interval). VE was done using volume rendering technique with 1 cm distance between images and 120 viewing angle. Two masked readers were asked to determine the number and location of the lesions. Seven patients underwent an abdominal CT during one breathhold after placement of a duodenal tube and filling of the small bowel with methyl cellulose contrast solution. VE images were compared with the axial slices with respect to detectability of pathology. With the 7/7/4 protocol only the 4-mm lesions were visualised with fuzzy contours. The 3/5/2 protocol showed both 4-mm lesions, one 3-mm lesion and one false positive lesion. The 3/5/1 protocol showed both 4-mm and both 3-mm (one uncertain) lesions with improved sharpness, and no false positive lesions. One 2-mm and one 1-mm lesion were additionally seen with the 1.5/3/1 protocol. Path definition was difficult in sharp turns or kinks in the lumen. In all patients, no difference was found between VE and axial slices for bowel pathology; however, axial slices showed 'outside' information that was not included in VE. We conclude that the 3/5/2 protocol may be regarded as an optimal compromise between lesion detection, coverage during one breathhold, and number of reconstructed images in patients; round lesions of 4 mm in diameter can be detected with high certainty.

    An 82-year-old Japanese man visited our hospital with abdominal fullness accompanied by lower abdominal pain. He presented with small bowel obstruction due to multiple diospyrobezoars. The bezoars were successfully removed without any surgical intervention by the administration of Coca-Cola Zero through a long intestinal tube and subsequent endoscopic manipulation. Such a combination may be the treatment of choice for small bowel obstruction due to bezoars.

    To investigate the clinical findings of patients who underwent surgery for small bowel obstruction following a previous operation for colorectal cancer. We assessed consecutive patients operated on for peritoneal metastasis with small bowel ileus. We evaluated the clinical characteristics of 7 consecutive patients with malignant small bowel ileus due to recurrent colorectal cancer with peritoneal metastasis. 1) Primary cancer location: descending colon, 2 cases (28.6%); sigmoid colon, 1 case (14.3%); and rectum, 4 cases (57.1%). 2) Peritoneal dissemination grade: P2, 1 case (14.3%); and P3, 6 cases (85.7%). 3) Liver metastasis grade: H1, 1 case (14.3%); H2, 5 cases (71.4%); and H3, 1 case (14.3%). 4) Lymph node metastasis grade: N2, 1 case (14.3%); and N3, 6 cases (85.7%). 5) Extra-abdominal metastasis: multiple lung metastases were detected in 3 cases (42.9%). 6) Pathological type: moderately differentiated tubular adenocarcinoma (tub2), 3 cases (42.3%); poorly differentiated adenocarcinoma (por), 1 case (14.3%); and mucinous adenocarcinoma (muc), 3 cases (42.3%). The differentiated type (tub2) was more common than the undifferentiated types(por and muc). 7) Malignant small bowel stenosis and/or obstruction: there were 3 or more cases with stenosis and/or obstruction in jejunum and ileum. 8) OPERATIVE PROCEDURE: gastrostomy was performed in 2 cases (28.6%); nephrostomy was performed in 1 case (14.3%); gastrostomy with nephrostomy was performed in 1 case (14.3%); and probe laparotomy was performed in 3 cases (42.9%). 9) Survival time of patients with recurrent colorectal cancer, from readmission to death: 0.5-1 month, 3 cases (42.9%); 1-1.5 months, 3 cases (42.9%); and 1.5-3 months, 1 case (14.3%). All patients died in less than 3 months. The prognosis of the malignant small bowel ileus due to recurrent colorectal cancer with peritoneal metastasis is very bad.

    Small-bowel adenocarcinoma is rare and fatal. Because of data paucity, there is a tendency to extrapolate treatment from colon cancer, particularly in the adjuvant stetting. The purpose of this study was to evaluate the current surgical and adjuvant treatments of small-bowel adenocarcinoma and compare with colon cancer. This was a retrospective cohort study. The linked Surveillance, Epidemiology, and End Results and Medicare database was used at a tertiary referral hospital. Patients with small-bowel adenocarcinoma and colon cancer identified from 1992 to 2010, using International Classification of Diseases for Oncology, 3 Revision, site, behavior, and histology codes were included. Overall survival and cancer-specific survival were estimated using the Kaplan-Meier method and competing risk analysis. A total of 2123 patients with small-bowel adenocarcinoma and 248,862 patients with colon cancer were identified. Five-year overall survival rates for patients with small-bowel adenocarcinoma and colon cancer were 34.9% and 51.5% (p bowel adenocarcinoma (73.0%) underwent surgery, compared with 177,017 patients with colon cancer (71.1%). The proportion of patients who received chemotherapy was similar, at 21.3% for small bowel and 20.0% for colon. In contrast to colon cancer, chemotherapy did not improve overall or cancer-specific survival for patients with small-bowel adenocarcinoma, regardless of stage. Predictors of poor survival for small-bowel adenocarcinoma on multivariate analysis included advanced age, black race, advanced stage, poor tumor differentiation, high comorbidity index, and distal location. Chemotherapy did not confer additional survival benefit compared with surgery alone (HR, 1.04 (95% CI, 0.90-1.22)). This was a retrospective review. The reliance on Medicare data limited granularity and may have affected the generalizability of the results. The prognosis for small-bowel adenocarcinoma is worse than that for colon cancer, and only surgery improves

    Full Text Available Coeliac disease is associated with an increased risk of malignancy, not only of intestinal lymphoma but also of small intestinal adenocarcinoma which is 82 times more common in patients with celiac disease than in the normal population. We report three additional cases of a small bowel adenocarcinoma in the setting of coeliac disease in order to underline the epidemiological features, clinicopathological findings, and therapeutic approaches of this entity based on a review of the literature. The three patients underwent a surgical treatment followed by adjuvant chemotherapy based on capecitabine/oxaliplatin regimen, and they have well recovered.

    Purpose: To evaluate the efficacy of breathhold MRI following enteroclysis with addition of oral magnetic particles to study the extension, detection of stenoses and extraluminal manifestations in Crohn's disease. Results: Typical findings were marked bowel wall thickening with strong contrast enhancement. 95.8% of affected small bowel segments and 94.7% of stenoses were correctly detected by MRI. All four fistulas were detected and important extraluminal findings were seen in 6/18 patients. Additionally, one ileoileal and two ileosigmoidal adhesions, two extraluminal abscesses and affection of the right ureter were delineated. Conclusion: MRI in Crohn's disease offers the potential to avoid radiation exposure in this relatively young patient group. Important additional findings relevant to indication of surgery are seen in approximately one third of cases. The replacement of transduodenal intubation by oral contrast application remains to be further studied. (orig./AJ) [de

    Many of the abdominal foreign bodies are due to accidental ingestion. Our objective in this case report is to emphasize the importance of the enquiry about the foreign body in the differential diagnosis of acute abdominal pain. According to our knowledge, this is the first report of bowel perforation caused by paper ingestion. A 14-year-old boy with abdominal pain underwent exploratory laparotomy and was found to have abdominal pus and ileal perforation. A crumpled paper was found at the site of perforation. Postoperative enquiry revealed that the patient had ingested 10 crumpled papers. We highlight that recording the history is an important aspect in the management of patients with acute abdominal pain and that foreign bodies should be included in its differential diagnosis.

    To determine whether inflammatory bowel disease (IBD) influences the risk of acute pancreatitis. We identified 11,909 patients diagnosed with IBD between 2000 and 2010 from Taiwan National Health Insurance Research Database as the study cohort. A comparison cohort comprised 47,636 age-matched patients without IBD. Both cohorts were followed-up until the end of 2010 or until being censored. Cox proportional hazards regression models were used to study the effects of IBD on the risks of acute pancreatitis. The overall incidence of acute pancreatitis was 3.56-fold higher in the study cohort than in the comparison cohort (31.8 vs 8.91 per 10,000 person-years, crude hazard ratio [HR] = 3.56, 95% confidence interval [CI] = 2.96-4.28). After adjustment for age, sex, and comorbidities, namely alcohol-related disease, biliary stone, hypertension, hyperlipidemia, diabetes mellitus, obesity, hepatitis B, hepatitis C, hypertriglyceridemia, cardiovascular diseases, chronic kidney disease, chronic obstructive pulmonary disease, and hypercalcemia, the adjusted HR for acute pancreatitis was 2.93-fold higher (95% CI = 2.40-3.58) in the study cohort than in the comparison cohort. IBD is a risk factor for acute pancreatitis. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Full Text Available Ulcers of the small bowel are rare, and in most cases are due to infections, inflammatory bowel diseases, malignancies or drugs. When none of these causes is recognized, they are classified as ‘nonspecific’ or idiopathic. Such lesions are uncommon, and in most cases present with occlusion. A case of a middle-aged woman with iron deficiency anemia due to occult bleeding, with negative gastroscopy and colonoscopy is presented. The diagnosis of a small bowel pathology resembling Crohn’s disease was made by small bowel follow through and small intestine contrast ultrasonography. An ileal ulcer was identified at surgery, and after resection the patient experienced a stable recovery from the anemia without ulcer recurrence. Neither histology nor clinical or biochemical features suggested the diagnosis of an inflammatory bowel disease. Other possible causes were unlikely and the lesion was therefore diagnosed as idiopathic. This report also focuses on the need and the modality to investigate the small bowel in iron deficiency anemia patients.

    To assess the clinical outcomes of the transcatheter microcoil embolization in patients with active lower gastrointestinal (LGI) bleeding in the small bowel, as well as to compare the mortality rates between the two groups based on the visualization or non-visualization of the bleeding focus determined by an angiography. We retrospectively evaluated all of the consecutive patients who underwent an angiography for treatment of acute LGI bleeding between January 2003 and October 2007. In total, the study included 36 patients who underwent a colonoscopy and were diagnosed to have an active bleeding in the LGI tracts. Based on the visualization or non-visualization of the bleeding focus, determined by an angiography, the patients were classified into two groups. The clinical outcomes included technical success, clinical success (no rebleeding within 30 days), delayed rebleeding (> 30 days), as well as the major and minor complication rates. Of the 36 patients, 17 had angiography-proven bleeding that was distal to the marginal artery. The remaining 19 patients did not have a bleeding focus based on the angiography results. The technical and clinical success rates of performing transcatheter microcoil embolizations in patients with active bleeding were 100% and 88%, respectively (15 of 17). One patient died from continued LGI bleeding and one patient received surgery to treat the continued bleeding. There was no note made on the delayed bleeding or on the major or minor complications. Of the 19 patients without active bleeding, 16 (84%) did not have recurrent bleeding. One patient died due to continuous bleeding and multi-organ failure. The superselective microcoil embolization can help successfully treat patients with active LGI bleeding in the small bowel, identified by the results of an angiography. The mortality rate is not significantly different between the patients of the visualization and non-visualization groups on angiography

    Some patients previously diagnosed with irritable bowel syndrome (IBS) may develop microscopic colitis or small intestinal bacterial overgrowth (SIBO). To estimate the prevalence of microscopic colitis and SIBO in patients with IBS, to evaluate the symptoms and the efficacy of treatment. We examined patients with IBS admitted in our clinic during a three-year period. We identified patients with microscopic colitis by performing total colonoscopy with multiple biopsies from normal intestinal mucosa and those with SIBO by performing a H2-breath test with glucose. We compared the symptoms and the effectiveness of the treatment. Out of the 132 patients initially diagnosed with IBS 3% (n=4) had microscopic colitis and 43.9% (n=58) had SIBO. Diarrhea was the main symptom in patients with microscopic colitis and SIBO (p=0.041), while abdominal pain, abdominal bloating and flatulence were prominent in IBS patients (p=0.042; p=0.039; p=0.048). Specific treatment with rifaximin in SIBO patients negativated H2-breath test in 70.9% cases. Patients suspected to have irritable bowel syndrome should be evaluated for microscopic colitis and SIBO. The proper diagnosis and the specific treatment may cure some difficult cases of the so called "irritable bowel syndrome".

    Proper evaluation of the small intestine is achieved with the combination of intravenous contrast medium and large volume of neutral contrast medium administered orally to stretch the intestinal lumen and produce images for the assessment of the lumen, thickness and pattern of enhancement of the small intestine walls. Materials and methods: Between May 2007 and February 2009 we retrospectively collected 90 cases of mainly outpatients who consulted our clinic. They were prepared taking a liquid diet for 24 hours that had no residue and complete fasting 4 hours prior to the examination. A total of 2000 cc of water was administrated orally (divided in 500 cc, 75, 65, 25 and 15 minutes prior to the examination). Then 100 cc of contrast medium (OptirayTM ) were administered intravenously, at a rate of 4 cc/sec. An early arterial phase was performed 20 seconds after injection, and a portal phase 60 seconds after IV contrast administration. The studies were performed in a 16 channels, General Electric multidetector scanner, with 3.0 mm slices, with multiplanar reconstructions and MIP. Results: The studies were interpreted by a group body imaging radiologists. The most frequent findings were: diverticular disease, cystic lesions, neoplasia, Crohn's disease,ileitis, mechanical obstruction, hiatal hernia, cholelithiasis, hepatic hemangiomas, duodenal diverticulum, polyposis, intestinal mal rotation, and active bleeding. Conclusions: CT enterography is a useful and noninvasive technique for diagnosing small bowel disorders, allowing, in most cases, a satisfactory distension of the small bowel without the use of an enteral tube.

    Capsule endoscopy performed via the traditional peroral route is technically challenging in patients with dysphagia, gastroparesis, and/or abnormal upper-GI (UGI) anatomy. To describe the indications and outcomes of cases in which the AdvanCE capsule endoscope delivery device, which has recently been cleared by the Food and Drug Administration, was used. Retrospective, descriptive, case series. Tertiary care, university hospital. We report a case series of 16 consecutive patients in whom the AdvanCE delivery device was used. The study period was May 2005 through July 2006. Endoscopic delivery of the video capsule to the proximal small bowel by using the AdvanCE delivery device. Indications, technique, and completeness of small bowel imaging in patients who underwent endoscopic video capsule delivery. The AdvanCE delivery device was used in 16 patients ranging in age from 3 to 74 years. The primary indications for endoscopic delivery included inability to swallow the capsule (10), altered UGI anatomy (4), and gastroparesis (2). Of the 4 patients with altered UGI anatomy, 3 had dual intestinal loop anatomy (ie, Bilroth-II procedure, Whipple surgery, Roux-en-Y gastric bypass) and 1 had a failed Nissen fundoplication. In all cases, the capsule was easily deployed without complication, and complete small intestinal imaging was achieved. Small patient size. Endoscopic placement of the Given PillCam by use of the AdvanCE delivery device was safe and easily performed in patients for whom capsule endoscopy would otherwise have been contraindicated or technically challenging.

    Purpose: To determine whether hyperosmolar and effervescent agents proven individually to accelerate transit time in the barium small bowel examination have an additive effect when combined, surpassing that of either agent alone. Materials and methods: One hundred and forty-nine patients were randomised to four groups. Three hundred milliliters of barium sulphate alone was given to the first group. Fifteen milliliters of iodinated hyperosmolar contrast agent (Gastrografin, meglumine/sodium diatrizoate, Schering) was given in addition to barium sulphate to the second group while six packets of effervescent granules (Carbex, Ferring) were added for the third group. The final group was given a combination of both additives and barium sulphate. The time taken following ingestion for the contrast column to reach the caecum, as assessed by frequent interval fluoroscopy, was recorded. A subgroup of 32 patients were selected randomly from the four groups, 8 from each and assessed for quality of examination. Statistical assessments were made using Kruskal-Wallis and Mann-Whitney tests. Results: One hundred and nineteen patients were analysed after exclusions. The addition of accelerant to barium sulphate, both individually and in combination significantly reduced the small bowel transit time (p < 0.001). No significant difference existed between the additives when used with barium alone. The combined group had significantly faster transit times compared to the hyperosmolar group (p = 0.02). Differences between combined and effervescent groups tended towards significance (p = 0.09). No significant difference existed between groups when examination quality was assessed. Conclusion: These results suggest that the addition of combined effervescent and hyperosmolar agents to the barium suspension may significantly shorten the small bowel transit time without adversely affecting examination quality. This has implications for patient acceptability of the examination as well as

    Full Text Available We describe the ultrastructural abnormalities of the small bowel surface in 16 infants with persistent diarrhea. The age range of the patients was 2 to 10 months, mean 4.8 months. All patients had diarrhea lasting 14 or more days. Bacterial overgrowth of the colonic microflora in the jejunal secretion, at concentrations above 10(4 colonies/ml, was present in 11 (68.7% patients. The stool culture was positive for an enteropathogenic agent in 8 (50.0% patients: for EPEC O111 in 2, EPEC O119 in 1, EAEC in 1, and Shigella flexneri in 1; mixed infections due to EPEC O111 and EAEC in 1 patient, EPEC O119 and EAEC in 1 and EPEC O55, EPEC O111, EAEC and Shigella sonnei in 1. Morphological abnormalities in the small bowel mucosa were observed in all 16 patients, varying in intensity from moderate 9 (56.3% to severe 7 (43.7%. The scanning electron microscopic study of small bowel biopsies from these subjects showed several surface abnormalities. At low magnification (100X most of the villi showed mild to moderate stunting, but on several occasions there was subtotal villus atrophy. At higher magnification (7,500X photomicrographs showed derangement of the enterocytes; on several occasions the cell borders were not clearly defined and very often microvilli were decreased in number and height; in some areas there was a total disappearance of the microvilli. In half of the patients a mucus-fibrinoid pseudomembrane was seen partially coating the enterocytes, a finding that provides additional information on the pathophysiology of persistent diarrhea.

    Magnetic resonance (MR) imaging is the recommended technique for detection of small bowel lesions in Crohn's disease. We aimed to evaluate the impact of stricture findings obtained by MR imaging on patient outcomes using balloon-assisted enteroscopy (BAE) as a reference. Two hundred Crohn's disease patients undergoing both MR enterocolonography and BAE were prospectively followed up for at least 1 year. The presence of strictures detected by MR enterocolonography was compared with endoscopic findings. Moreover, the relationship between MR findings and surgery was evaluated. The accuracy of MR imaging for detection of small bowel strictures was defined by a sensitivity of 60.6% and a specificity of 93.4%. Major strictures (diameter less than 10 mm or with internal fistula), long strictures (length 10 mm or greater), and prestenotic dilatation were predictors of stricture detection by MR imaging (P = 0.001, 0.017, and 0.002 respectively). Surgery was performed in 31.6% of patients (18 of 57) in the MR-positive-BAE-positive stricture group and in 10.8% of patients (4 of 37) in the MR-negative-BAE-positive stricture group. Multiple regression analysis showed MR-positive-BAE-positive strictures were an independent risk factor for surgery (P = 0.002 at 6 months and P < 0.001 at 1 year). The surgery-free rate in the MR-negative-BAE-positive stricture group was significantly lower than that in nonstricture group at 1 year (P = 0.001). The specificity of MR imaging for detection of small bowel strictures was clinically sufficient, and the MR procedure could detect critical strictures, which was a predictive factor for surgery. But MR-negative-BAE-positive strictures were also associated with an increased risk compared with no strictures after 1 year of follow-up.

    To consolidate duodenum and small bowel toxicity data from clinical studies with different dose fractionation schedules using the modified linear quadratic (MLQ) model. A methodology of adjusting the dose-volume (D,v) parameters to different levels of normal tissue complication probability (NTCP) was presented. A set of NTCP model parameters for duodenum toxicity were estimated by the χ(2) fitting method using literature-based tolerance dose and generalized equivalent uniform dose (gEUD) data. These model parameters were then used to convert (D,v) data into the isoeffective dose in 2 Gy per fraction, (D(MLQED2),v) and convert these parameters to an isoeffective dose at another NTCP (D(MLQED2'),v). The literature search yielded 5 reports useful in making estimates of duodenum and small bowel toxicity. The NTCP model parameters were found to be TD50(1)(model) = 60.9 ± 7.9 Gy, m = 0.21 ± 0.05, and δ = 0.09 ± 0.03 Gy(-1). Isoeffective dose calculations and toxicity rates associated with hypofractionated radiation therapy reports were found to be consistent with clinical data having different fractionation schedules. Values of (D(MLQED2'),v) between different NTCP levels remain consistent over a range of 5%-20%. MLQ-based isoeffective calculations of dose-response data corresponding to grade ≥2 duodenum toxicity were found to be consistent with one another within the calculation uncertainty. The (D(MLQED2),v) data could be used to determine duodenum and small bowel dose-volume constraints for new dose escalation strategies. Copyright © 2014 American Society for Radiation Oncology.

    Irritable bowel syndrome (IBS) is one of the most common reason for gastroenterology consultations. The diverse in symptomatology of the disease comes from its rich etiopathogenesis. Recently studies talk about infectious etiology of IBS and because of that it is necessary to expand its diagnostics by small intestinal bacterial overgrowth (SIBO) test. The aim of this study was to evaluate the prevalence of small intestinal bacterial overgrowth in patients with constipation (IBS-C) and diarrhea (IBS-D) irritable bowel syndrome with regard to nutrition. The study involved 46 subjects (33 women and 13 men) in average age of 44 years, which were divided into two groups: diarrhea and constipation IBS. All patients underwent hydrogen breath test studying bacterial overgrowth in the small intestine. In addition, each person had fulfilled a feeding questionnaire. Student's t-test, Pearson test. It has been shown that there is no statistical significances between the prevalence of SIBO in form of diarrheal IBS and constipation IBS and gender. Average value of increments of hydrogen in breath during the test was higher in IBS-C in comparison with IBS-D, which was the highest in the intestine bacterial overgrowth in patients with IBS-C. STATISTICAL ANALYSIS showed that there is no relationship between the type and frequency of consumption of milk, meat, fruit and vegetables, sweets and coffee and the prevalence of SIBO in form of diarrhea and constipation IBS. The occurrence of constipation or diarrhea irritable bowel syndrome is not related to gender. SIBO is more common in patients with IBS-C than in IBS-D group. There is no relationship between the type of food consumed and the amount of SIBO in people with IBS. Type of food intake do not affect the status of the intestinal flora of people with IBS.

    Following segmental irradiation of the small bowel, 5 of 64 cats demonstrated ectopic intestinal glands in the submucosal tissue. In addition, one of these 5 cats had foci of abnormal glands in the muscularis mucosae. In 2 of the 5 animals, cellular polymorphism, nucleolar irregularity and loss of cellular polarity were present in irradiation-induced ectopic intestinal glands. The review of the literature indicates that intestinal irradiation may induce intestinal adenocarcinomas with metastatic growth. The possibility that ectopic intestinal glands are precancerous lesions in the irradiated cat is discussed. (Auth.)

    Full Text Available Meckel’s diverticulum occurs in 2% of the general population and majority of patients remain asymptomatic. Gastrointestinal bleeding is the most common presentation in the paediatric population. While asymptomatic and incidentally found Meckel’s diverticulum may be left alone, surgery is essential for treating a symptomatic patient. Despite advances in imaging and technology, pre-operative diagnosis is often difficult. We present a first report of an unusual mechanism of small bowel obstruction due to Meckel’s diverticulitis in a paediatric patient. The diagnosis was only apparent at laparotomy.

    BACKGROUND: Small bowel cancer (SBC) is a rare and highly heterogeneous disease in respect to both anatomical distribution and histological morphology. We aimed to conduct a Danish nationwide population-based cohort study of the incidence of, phenotypes of, stage of, synchronous/metachronous cancer...... to the anatomical origin and morphological subtype. Patients were followed up from the date of cancer diagnosis to the date of emigration, death or the end of the study (31 December 2010). RESULTS: SBC was diagnosed in 1088 patients during 1994-2010. The total annual incidence of SBC was 1.10 per 100,000 [95...

    Angiomatous malformation is the most common vascular abnormality, accounting for 30-40% cases of obscure GI bleeding from small bowel. Surgical resection is the treatment of choice in severe or recurrent hemorrhage requiring multiple blood transfusions. However, the diffuse nature of the lesions poses a challenge to localize them accurately preoperatively, for exact resection. We present a case in which we have used selective mesenteric angiography with selective cannulation and exact localization of the lesion by injecting dye such as methylene blue, indigo carmine, and fluorescein, to localize the angiomatous malformation before surgical resection and also to determine the exact resection to be done.

    The present study aimed to determine the diagnostic yield of OMOM capsule endoscopy for small bowel diseases in adults. A total of 89 patients, including 45 cases of obscure abdominal pain, 22 of chronic diarrhea, 18 of obscure gastrointestinal bleeding and 4 of obscure anemia were enrolled in the present study. The transit time of the endoscopy capsule in the digestive tract was recorded and the testing results were analyzed. All detections were completed except for four capsule retentions and the completion rate was 95.51%. The average transit time of the endoscopy capsule in the esophagus, stomach and small intestine was 62.18±64.23 sec, 67.46±63.13 and 346.53±102.81 min, respectively. Of the 89 patients, 54 (60.67%) were found to have lesions, among which 19 had mucosal erosion (21.35%), 15 had anabrosis (16.85%), 9 were diagnosed with polyps (10.11%), 5 with angiodysplasia (5.62%); furthermore, tumors were identified in 5 patients (5.62%) and ancylostomiasis in 1 patient (1.12%). The results confirmed the feasibility and validity of OMOM capsule endoscopy for diagnosing small bowel diseases in adults.

    Full Text Available Abstract Background A strong dose-volume relationship exists between the amount of small bowel receiving low- to intermediate-doses of radiation and the rates of acute, severe gastrointestinal toxicity, principally diarrhea. There is considerable interest in the application of highly conformal treatment approaches, such as intensity-modulated radiation therapy (IMRT, to reduce dose to adjacent organs-at-risk in the treatment of carcinoma of the rectum. Therefore, we performed a comprehensive dosimetric evaluation of IMRT compared to 3-dimensional conformal radiation therapy (3DCRT in standard, preoperative treatment for rectal cancer. Methods Using RTOG consensus anorectal contouring guidelines, treatment volumes were generated for ten patients treated preoperatively at our institution for rectal carcinoma, with IMRT plans compared to plans derived from classic anatomic landmarks, as well as 3DCRT plans treating the RTOG consensus volume. The patients were all T3, were node-negative (N = 1 or node-positive (N = 9, and were planned to a total dose of 45-Gy. Pairwise comparisons were made between IMRT and 3DCRT plans with respect to dose-volume histogram parameters. Results IMRT plans had superior PTV coverage, dose homogeneity, and conformality in treatment of the gross disease and at-risk nodal volume, in comparison to 3DCRT. Additionally, in comparison to the 3DCRT plans, IMRT achieved a concomitant reduction in doses to the bowel (small bowel mean dose: 18.6-Gy IMRT versus 25.2-Gy 3DCRT; p = 0.005, bladder (V40Gy: 56.8% IMRT versus 75.4% 3DCRT; p = 0.005, pelvic bones (V40Gy: 47.0% IMRT versus 56.9% 3DCRT; p = 0.005, and femoral heads (V40Gy: 3.4% IMRT versus 9.1% 3DCRT; p = 0.005, with an improvement in absolute volumes of small bowel receiving dose levels known to induce clinically-relevant acute toxicity (small bowel V15Gy: 138-cc IMRT versus 157-cc 3DCRT; p = 0.005. We found that the IMRT treatment volumes were typically larger than that

    Obscure gastrointestinal bleeding is defined as bleeding of unknown origin, that persists or recurs after negative conventional barium contrast studies and upper and lower tract endoscopy. The causes of such a bleeding frequently arise in the small bowel, and they are represented by mucosal vascular abnormalities, neoplasms and other conditions such as Crohn's disease, Meckel's diverticulum, and vasculitis. Conventional barium contrast studies and push enteroscopy allow only a limited small bowel examination; moreover, intraoperative endoscopy may be inconclusive, since the small bowel is difficult to evaluate given its length and tortuous course. In the same way, angiographic diagnosis is stricktly related to the activity rate of hemorrhage. Wireless capsule endoscopy and multidetector-row CT enteroclysis are two recently developed minimally invasive techniques that may provide a complete small bowel examination, the first offering a direct visualization of the mucosal aspect, the second allowing evaluation of mural and extramural pathologies. This review is an update of the technique and clinical application of capsule endoscopy and multidetector-row CT enteroclysis in patients suffering from obscure small bowel bleeding.

    -jejunal transposition, resection of the proximal or distal half of the small intestine, and appropriate sham-operated controls. After two weeks, ileal-jejunal transposition led to pronounced growth of the transposed segment and also of the remaining intestinal segments. Plasma GLP-2 levels increased twofold, whereas...... GLP-2 levels in the intestinal segments were unchanged. In resected rats with reduced intestinal capacity, adaptive small bowel growth was more pronounced following proximal resection than distal small bowel resection. Circulating GLP-2 levels increased threefold in proximally resected animals...... with increased plasma levels of GLP-2, and GLP-2 seems to act in an endocrine as well as a paracrine manner....

    Purpose: To evaluate the incidence of gastrointestinal complications in patients with inflammatory bowel disease (IBD) receiving radiotherapy (RT) and to identify possibly avoidable factors associated with these complications. Methods and Materials: Twenty-four patients were identified and their records reviewed; all had a history of IBD before receiving RT to fields encompassing some portion of the gastrointestinal tract (Crohn's disease) or to the abdomen or pelvis (ulcerative colitis or IBD not otherwise specified). Results: Five of 24 patients (21%) experienced Grade ≥3 acute gastrointestinal toxicity; all 5 received concurrent chemotherapy. Two of 24 patients (8%) experienced Grade ≥3 late gastrointestinal toxicity. There were no significant correlations between complications and IBD type, prior IBD-related surgery, use of medications for IBD, or status of IBD. Conclusion: Patients with IBD may have an increased risk for severe acute RT-related gastrointestinal complications that is more modest than generally perceived, because all patients who had Grade ≥3 acute complications in this study had received concurrent chemotherapy (p=0.04). Further study is needed to assess this risk, as well as the impact of RT on these patients' future gastrointestinal morbidity

    The in vitro incorporation of 14 C acetate by the epidermis has been studied in patients with autosomal dominant ichthyosis and in patients with a dry, itchy, slightly scaly skin associated with a disorder of the small bowel. Analysis of 14 C acetate containing lipid moieties by thin layer chromatography has indicated that there are both quantitative and qualitative differences in the uptake of 14 C acetate between autosomal dominant ichthyosis and normal. In particular an increased incorporation into the triglyceride and phosphatidyl choline fractions was noted. No such differences were apparent in those patients with disorders of the small bowel. In addition the in vitro incorporation of radioactively labelled thymidine, proline and histidine has been studied in these patients. In both groups of patients the rate of incorporation of tritiated thymidine and histidine into epidermal macromolecules was found not to differ significantly from normal. On the other hand the rate of incorporation of tritiated proline was increased in both groups of patients. (author)

    Antiphospholipid syndrome is a multi-system disease characterized by the formation of thromboembolic complications and/or pregnancy morbidity, and with persistently increased titers of antiphospholipid antibodies. We report the case of a 50-year-old, previously healthy man who presented with fever and new-onset, dull abdominal pain. A contrast-enhanced computed tomography scan showed segmental small bowel obstruction, for which an emergency laparotomy was performed. Histopathologic examination of resected tissues revealed multiple intestinal and mesenteric thromboses of small vessels. Laboratory tests for serum antiphospholipid (anticardiolipin IgM) and anti-β2-glycoprotein I antibodies were positive. Despite proactive implementation of anticoagulation, steroid, and antibiotic therapies, the patient's condition rapidly deteriorated, and he died 22 d after admission. This case highlights that antiphospholipid syndrome should be suspected in patients with unexplainable ischemic bowel and intestinal necrosis presenting with insidious clinical features that may be secondary to the disease, as early diagnosis is critical to implement timely treatments in order to ameliorate the disease course.

    Full Text Available Background. Video capsule endoscopy (VCE is increasingly performed among the elderly for obscure bleeding. Our aim was to report on the utility of VCE to uncover unsuspected Crohn’s disease (CD in elderly patients. Methods. Retrospective review of VCE performed in elderly patients (≥70 y at a tertiary hospital (2010–2015. All underwent prior negative bidirectional endoscopies. CD diagnosis was based on consistent endoscopic findings, exclusion of other causes, and a Lewis endoscopic score (LS > 790 (moderate-to-severe inflammation. Those with lower LS (350–790 required histological confirmation. Known IBD cases were excluded. Results. 197 VCE were performed (mean age 78; range 70–93. Main indications were iron deficiency anemia (IDA, occult GI bleeding (OGIB, chronic abdominal pain, or diarrhea. Eight (4.1% were diagnosed as CD based on the aforementioned criteria. Fecal calprotectin (FCP was elevated in 7/8 (mean 580 μg/g. Mean LS was 1824. Small-bowel CD detected by VCE led to a change in management in 4/8. One patient had capsule retention secondary to NSAID induced stricture, requiring surgical retrieval. Conclusions. VCE can be safely performed in the elderly. A proportion of cases may have unsuspected small-bowel CD despite negative endoscopies. FCP was the best screening test. Diagnosis frequently changed management.

    Paediatric Chance fracture are rare lesions but often associated with abdominal injuries. We herein present the case of a seven years old patient who sustained an entrapment of small bowel and an ureteropelvic disruption associated with a Chance fracture and spine dislocation following a traffic accident. Initial X-rays and computed tomographic (CT) scan showed a Chance fracture with dislocation of L3 vertebra, with an incarceration of a small bowel loop in the spinal canal and a complete section of the left lumbar ureter. Paraplegia was noticed on the initial neurological examination. A posterior L2-L4 osteosynthesis was performed firstly. In a second time she underwent a sus umbilical laparotomy to release the incarcerated jejunum loop in the spinal canal. An end-to-end anastomosis was performed on a JJ probe to suture the left injured ureter. One month after the traumatism, she started to complain of severe headaches related to a leakage of cerebrospinalis fluid. Three months after the traumatism there was a clear regression of the leakage. One year after the trauma, an anterior intervertebral fusion was done. At final follow-up, no neurologic recovery was noticed. In case of Chance fracture, all physicians should think about abdominal injuries even if the patient is asymptomatic. Initial abdominal CT scan and magnetic resonance imaging provide in such case crucial info for management of the spine and the associated lesions. PMID:27672641

    In practice, small bowel cancer is a rare entity. The most common histologic subtype is adenocarcinoma. Adenocarcinoma of the small bowel (SBA) is challenging to diagnose, often presents at a late stage and has a poor prognosis. The treatment of early-stage SBA is surgical resection. No standard protocol has been established for unresectable or metastatic disease. We report here on a 26-year-old man with SBA in the jejunum, lacking specific symptoms and with a delay of 6 months in diagnosis. The diagnosis was finally achieved with a combination of balloon-assisted enteroscopy, computed tomography scans, positron emission computed tomography scans and the values of carcino-embryonic antigen and carbohydrate antigen 19-9. The patient underwent segmental intestine with lymph node resection, followed by eight cycles of FOLFOX palliative chemotherapy with good tolerance. As of the 11-month postoperative follow-up, there has been no evidence of recurrent disease. This case is reported to arouse a clinical suspicion of SBA in patients with abdominal pain of unknown cause. We also provided evidence in this case of a response to palliative chemotherapy with FOLFOX. Because the incidence of SBA is very low, there is a need for further studies to evaluate the possible application of newer investigative agents and strategies to obtain a better outcome within the framework of international collaborations.

    AIMS: The aim of the present study to examine the use of a modified water-soluble follow-through in the diagnosis and management of small bowel obstruction (SBO). MATERIALS AND METHODS: Sixty-two patients were recruited to the study: 33 into the control group and 29 into the study group. A modified small bowel follow-through (SBFT) was performed in the study group patients. The control group was managed conventionally. Assessment was made by questionnaire documenting initial surgical diagnosis and likelihood of operative intervention, final diagnosis and surgical outcome (operative versus non-operative). RESULTS: SBFT changed the diagnosis in 12/24 of the study group (p<0.01). In the study group 8/24 proceeded to surgery whereas 19/33 underwent laparotomy in the control group, representing a relative risk reduction of 52%, but this was not statistically significant (0.10>p>0.05, chi-squared test). CONCLUSION: SBFT remains a valid and useful tool in surgical management of SBO. In particular it aids diagnostic confidence in planning surgical intervention, particularly in uncomplicated patients.

    Full Text Available BACKGROUND: Recent molecular studies have revealed a highly complex bacterial assembly in the canine intestinal tract. There is mounting evidence that microbes play an important role in the pathogenesis of acute and chronic enteropathies of dogs, including idiopathic inflammatory bowel disease (IBD. The aim of this study was to characterize the bacterial microbiota in dogs with various gastrointestinal disorders. METHODOLOGY/PRINCIPAL FINDINGS: Fecal samples from healthy dogs (n = 32, dogs with acute non-hemorrhagic diarrhea (NHD; n = 12, dogs with acute hemorrhagic diarrhea (AHD; n = 13, and dogs with active (n = 9 and therapeutically controlled idiopathic IBD (n = 10 were analyzed by 454-pyrosequencing of the 16S rRNA gene and qPCR assays. Dogs with acute diarrhea, especially those with AHD, had the most profound alterations in their microbiome, as significant separations were observed on PCoA plots of unweighted Unifrac distances. Dogs with AHD had significant decreases in Blautia, Ruminococcaceae including Faecalibacterium, and Turicibacter spp., and significant increases in genus Sutterella and Clostridium perfringens when compared to healthy dogs. No significant separation on PCoA plots was observed for the dogs with IBD. Faecalibacterium spp. and Fusobacteria were, however, decreased in the dogs with clinically active IBD, but increased during time periods of clinically insignificant IBD, as defined by a clinical IBD activity index (CIBDAI. CONCLUSIONS: Results of this study revealed a bacterial dysbiosis in fecal samples of dogs with various GI disorders. The observed changes in the microbiome differed between acute and chronic disease states. The bacterial groups that were commonly decreased during diarrhea are considered to be important short-chain fatty acid producers and may be important for canine intestinal health. Future studies should correlate these observed phylogenetic differences with functional changes in the intestinal

    Amanda D. Rice

    2013-02-01

    Full Text Available Background: Adhesion formation is a widely acknowledged risk following abdominal or pelvic surgery. Adhesions in the abdomen or pelvis can cause or contribute to partial or total small bowel obstruction (SBO. These adhesions deter or prevent the passage of nutrients through the digestive tract, and may bind the bowel to the peritoneum, or other organs. Small bowel obstructions can quickly become life-threatening, requiring immediate surgery to resect the bowel, or lyse any adhesions the surgeon can safely access. Bowel repair is an invasive surgery, with risks including bowel rupture, infection, and peritonitis. An additional risk includes the formation of new adhesions during the healing process, creating the potential for subsequent adhesiolysis or SBO surgeries. Objective: Report the use of manual soft tissue physical therapy for the reversal of adhesion-related partial SBOs, and create an initial inquiry into the possibility of nonsurgical lysis of adhesions. Case Reports: Two patients presenting with SBO symptoms due to abdominal adhesions secondary to abdominal and pelvic surgery were treated with manual soft tissue physical therapy focused on decreasing adhesions. Conclusions: Successful treatment with resolution of symptom presentation of partial SBO and sustained results were observed in both patients treated.

    Summary: Crohn's disease is more likely a systemic disease governed by a shift in the immune response, thus affecting the whole MALT system. Its treatment should be as conservative as possible and surgery is usually taking place after complications like indolent fistulations, stenoses, bleeding, or bowel perforation started. Standard radiological methods to check the extent of the disease are loaded either with certain radiation exposure (enteroclysis, CT) or lack standardization (ultrasound). The aim of this small study was to evaluate the worth of ultrasound-enteroclysis in detecting the extent and complications of the Crohn's disease in surgically treated patients. Material and methods: Since 1997, when we started with the ultrasound-enteroclysis, 246 surgical performances were involved into our study. Out of them, 181 had conventional abdominal intestinal ultrasound as well as conventional enteroclysis within 1 week. Remaining 65 cases were diagnosed by the ultrasound-enteroclysis. Intestinal ultrasound was performed on the Ultramark 3000 HDI device with autofocussable convex 5 MHz and linear 7.5 MHz probes or nowadays ATL 5000 HDI, 7-12 MHz linear probe. No contrast enhancement was used. Enteroclysis was done with the Micropaque suspension diluted 1:1 with HP-7000 300 ml with its application rate up to 75 ml/min followed by HP-7000 solution 2000 ml, application rate of 120 ml/min. The patients with ultrasound-enteroclysis were applied HP 7000 solution only (2000 ml, rate 100 ml/s) via an enteroclysis catheter. All investigations were video-recorded. Results: Consent with the per-operative finding was reached in 162 from 181 enteroclyses and in 169 of 181 ultrasounds. Ultrasound-enteroclysis was precise in 61 cases from 65. Among these, 60 patients had the recurrence during the treatment proved by clinical and laboratory results. This re-activation was clearly revealed in 38 from 43 cases by enteroclysis, 41 from 43 by US and in 16 from 17 by

    MRI of the small bowel with positive contrast from orally administered contrast agent is a promising non-invasive imaging method. The aim of our study was to introduce small bowel MRI in a display format that clinicians are accustomed to and that maximizes the amount of information visualized on a single image. Twelve healthy volunteers, median age 32 years (range 18-49 years) participated in the study. A mixture of 20 ml Gd-DOTA (Dotarem), 0.8 g/kg body weight psyllium fibre (Metamucil) and 1.2 l water were sequentially administered over a period of 4 h. Imaging was performed on a 1.5 T unit (Philips Gyroscan, Intera). Fat-saturated, 3D, gradient echo imaging was performed while the patient was in apnea (30 s). Bowel motion was reduced with 40 mg intravenously administered scopolamine (Buscopan). A 3D, gradient-enhanced, volume rendering technique was applied to the 3D data sets. Standard projections [left anterior oblique (LAO), right anterior oblique (RAO), supine and prone] resembling conventional enteroclysis were successfully generated within fewer than 10 min processing time. Reconstructions were reproducible and provided an entire overview of the small bowel. In addition thin-slab volume rendering allowed an overlap-free display of individual structures. Positive contrast from orally administered contrast agent, combined with a gradient enhanced volume rendering method, allows the reconstruction of the small bowel in a pattern resembling conventional double-contrast enteroclysis. Segmental display without overlay is possible. (orig.)

    Objective. Small intestinal mucosal damage can result in decreased lactase activity (LA). When LA is low in a small-bowel biopsy (SBB) specimen, a reduction of dietary lactose intake is usually advised. This is often done by reducing dietary dairy products, which also reduces the intake of calcium,

    Gastrointestinal (GI) bleeding in pediatric patients has several causes. Vascular malformation of the small bowel is a rare disease leading to pediatric GI bleeding. To our knowledge, few reports describe ultrasound and computed tomography findings of venous malformations involving the small bowel. We present a case of long-segmental and circumferential vascular malformation that led to GI bleeding in a pre-school aged child, focusing on the radiologic findings. Although vascular malformation including of the GI tract is rare in children, it should be considered when GI bleeding occurs in pediatric patients

    A comparative retrospective study was conducted to evaluate diagnostic findings between small bowel follow-through (SBFT) and wireless capsule endoscopy in the presence of obscure gastrointestinal bleeding. A convenience sample of 31 patients with previous negative upper and lower endoscopy was included in the study. Wireless capsule endoscopy established a significant source of obscure gastrointestinal bleeding 53% of the time. The diagnostic capacity of radiographic SBFT was measured at 17% as compared with that of the wireless capsule endoscopy. The clinical findings along with the digital images obtained from the wireless capsule endoscopy was found to be the optimum diagnostic tool in the evaluation of obscure gastrointestinal bleeding in the small bowel.

    Ischemia reperfusion injury (IRI) is a major field of study in small bowel transplantation because of its implications regarding intestinal immunity. In this study, we have introduced some variations to the described models of IRI in pigs to make possible a complete isolation of the small bowel for IRI studies. In swine, two anatomical barriers make impossible a complete isolation of the small bowel at the origin of superior mesenteric artery (SMA) and vein (SMV): the main colic vessels, which originate distally to form SMA and SMV, and the blood supply of the distal portion of the duodenum and the cephalic part of the pancreas. In a group of Large White pigs (n = 5), we have performed a complete isolation of the small bowel, including sub-total colectomy and pancreaticoduodenectomy. Both SMA and SMV were isolated at the origin from the aorta and at the junction of the splenic vein, respectively. Intestinal continuity was restored with duodenojejunal anastomosis and with ileotransverse colon anastomosis. One pig died on postoperative day 5 from intestinal occlusion due to adhesions. The remaining four pigs were killed on postoperative day 7 after an uneventful postoperative course. No complications were found at autopsy. In swine, resection of part of the pancreas and duodenum and removal of the large bowel does not affect short-term survival, allowing a full isolation of the entire small bowel mimicking the transplantation procedure. Thus, this model appears to be attractive for IRI studies in the field of intestinal transplantation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Crohn's disease recurrence after an ileocecal resection is common; yet, its pathophysiology is poorly understood and available treatment is suboptimal. The purpose of this study was to examine the bacterial, local, and systemic immune changes that follow ileocolonic anastomosis in a rodent model of Crohn's disease, the interleukin-10 gene-deficient (IL-10 null) mice. We divided wild-type and IL-10 null mice into three treatment groups: ileocolonic anastomosis, sham operation (ileo-ileal anastomosis), and control group without an operation. We sacrificed mice at 6 and 15 wks after the operation. At 6 wks, we assessed bacterial changes using the denaturing gel electrophoresis and similarity coefficient calculation. At both time points, we examined the small bowel for inflammation and fibrosis with histology. We measured the interferon gamma secretion by splenocytes stimulated with gastrointestinal bacterial antigens and splenocyte composition as a marker of systemic response. At 6 wks, ileocolonic anastomosis resulted in increased similarity in bacterial species between the ileum and colon. The ileocolonic anastomosis did not lead to significant inflammation in the small intestine, but it resulted in an increased collagen deposition in all animals undergoing surgery, the most pronounced fibrosis of which was present in IL-10 null mice 15 wks after ileocolonic anastomosis. Furthermore, this was associated with significantly increased interferon gamma secretion by bacterial antigen-stimulated splenocytes and a decreased number of CD11+ cells in the same experimental group. Ileocolonic anastomosis leads to bacterial changes in the terminal ileum. In the genetically susceptible host, it is associated with small bowel fibrosis and systemic immune alterations. The composition of immune cells in the spleen is altered and splenocytes hypersecrete proinflammatory cytokine (interferon gamma) when challenged with gastrointestinal bacterial antigens.

    Assessing predictors of acute bowel toxicity after whole-pelvis irradiation (WPRT) Image-guided Tomotherapy with simultaneous integrated boost on prostate/prostate bed. In the period March 2005-April 2009, 178 patients were treated with radical or adjuvant/salvage intent with WPRT Tomotherapy. Median dose to the pelvic nodes was 51.8 Gy/28 fractions while concomitantly delivering 65.5-74.2 Gy to prostate/prostatic bed. The impact of many anatomical and clinical parameters on ≥ Grade 2 acute bowel toxicity was investigated by logistic analyses. Only 15/178 patients (8.4%) experienced Grade 2 toxicity (none Grade 3). Main predictors at univariate analysis were nodal CTV (CTVN ≥ 380 cc; OR: 3.7, p=0.017), treatment duration (bowel toxicity after WPRT Tomotherapy is mild, relatively rare and associated to larger CTVN and older age. While efforts to further reduce it do not appear to be relevant, the pre-treatment assessment of "high-risk" patients may help physicians in better managing symptoms. A prospective validation would be very important in confirming these results and in better refining dose-volume bowel effects including symptoms milder that the ones here investigated and retrospectively assessed.

    To evaluate the functioning and effectiveness of a reversed jejunal segment after extensive small bowel resection, we continuously measured the postoperative bowel motility (using bipolar electrodes and/or contractile strain gage force transducers) in interdigestive and postprandial conscious dogs at 2 to 5 weeks after surgery. The fasting duodenal migrating myoelectric (or motor) complex (MMC) occurred at markedly longer intervals in dogs with a 20-cm reversed jejunal segment created after 75% to 80% extensive small bowel resection (group 3) than in dogs that received extensive resection alone (group 2) or dogs that underwent construction of a reversed jejunal segment without bowel resection (group 1). The MMC arising from the duodenum was often interrupted at the jejunum above the proximal anastomosis and did not migrate smoothly to the reversed segment or terminal ileum in group 3. In addition, brief small discordant contractions were frequent in the reversed segment and the jejunum above the proximal anastomosis in group 3. The duration of the postprandial period without duodenal MMC activity was significantly prolonged in groups 2 and 3. These results suggest that the transit time and passage of intestinal contents were delayed and that the periodical MMC was disturbed in group 3. The delay of transit time was due to prolongation of the interval between duodenal MMCs, the interruption of MMC propagation at the jejunum above the proximal anastomosis, the dominance of MMCs that followed the inherent anatomical continuity of the bowel, and discordant movements across the proximal anastomosis. Functional obstruction could be a potential problem in a 20-cm reversed jejunal segment inserted after extensive small bowel resection.

    BACKGROUND: Ganglioneuroma is a rare tumour of neural crest origin, which arises from maturation of a neuroblastoma. While previously considered to be non-functioning, they are now known to be frequently endocrinologically active. AIMS AND METHODS: We report a case of a massive retroperitoneal ganglioneuroma presenting with small bowel obstruction in an adult, 18 years after initial diagnosis. Urinary dopamine levels were elevated, but other catecholamines were within normal limits. This is the first report in the English-language literature of a retroperitoneal ganglioneuroma presenting with or causing intestinal obstruction. We also review the metabolic, radiological, and histological features of these tumours. Relevant publications were identified from a Medline search using the MeSH headings \\'ganglioneuroma\\

    Full Text Available The use of seatbelts has increased significantly in the last twenty years, leading to a decrease in mortality from road traffic accidents (RTA. However, this increase in seatbelt use has also led to a change in the spectrum of injuries from RTA; abdominal injuries, particularly intestinal injuries have dramatically increased with the routine use of seatbelts. Such intestinal injuries frequently result from improper placement of the “lap belt”. We present 3 cases in which passengers wearing a seatbelt sustained significant devascularisation injuries to the small bowel requiring emergency surgical intervention. A high index of suspicion is crucial in such cases to prevent delays in diagnosis that can lead to severe complications and adverse outcomes. It is evident that while advocating seatbelt use, the importance of education in correct seatbelt placement should also be a focus of public health strategies to reduce RTA morbidity and mortality.

    This work evaluates carbon dioxide as a contrast medium for magnetic resonance imaging of the stomach and small bowel. Twelve healthy volunteers underwent rapid magnetic resonance imaging after oral administration of a carbon dioxide generating agent using a combination of breath-hold and interactive fluoroscopic imaging during breathing. Diagnostic-quality images were obtained in 100% of cases for the stomach and in 92, 75, 67 and 42% of cases for the duodenal segments 1-4, respectively. Visualisation of the jejunum and ileum proved unacceptable for clinical use and anti-peristaltic agents did not significantly influence the results. Further development of fast imaging and magnetic resonance interactive fluoroscopic methods may allow the use of carbon dioxide as a contrast medium for clinical imaging of the stomach and duodenum.

    Full Text Available Ileitis is defined as inflammation of the ileum. This condition includes ulcers, aphthous ulcers, erosions, and nodular or erythematous mucosa. Various etiologies are associated with ileitis. Crohn’s disease, ulcerative colitis, medications such as nonsteroidal anti-inflammatory drugs, infectious conditions, neoplasms, infiltrative disorders, vasculitides, spondyloarthritis, endometriosis, and radiation therapy-related conditions involve the ileum. However, the differential diagnosis of terminal ileitis can be difficult in many cases. Video capsule endoscopy (VCE has become a useful tool for the diagnosis of a variety of small bowel lesions. This review describes each of the various conditions associated with ileitis and the diagnostic value of VCE for ileitis, which may help identify and evaluate these conditions in clinical practice. Based on the information provided by VCE, a definitive diagnosis could be made using the patients’ medical history, clinical course, laboratory and ileocolonoscopic findings, radiologic imaging findings, and histologic findings.

    Despite stress being considered a key factor in the pathophysiology of the functional gastrointestinal (GI) disorder irritable bowel syndrome (IBS), there is a paucity of information regarding the ability of IBS patients to respond to acute experimental stress. Insights into the stress response in IBS could open the way to novel therapeutic interventions. To this end, we assessed the response of a range of physiological and psychological parameters to the Trier Social Stress Test (TSST) in IBS. Thirteen female patients with IBS and 15 healthy female age-matched control participants underwent a single exposure to the TSST. Salivary cortisol, salivary C-reactive protein (CRP), skin conductance level (SCL), GI symptoms, mood and self-reported stress were measured pre- and post-exposure to the TSST. The hypothalamic-pituitary-adrenal (HPA) axis response to the TSST was sustained in IBS, as shown by a greater total cortisol output throughout (p = 0.035) and higher cortisol levels measured by an area under the curve with respect to ground (AUCG) analysis (p = 0.044). In IBS patients, GI symptoms increased significantly during the recovery period following exposure to the TSST (p = 0.045). Salivary CRP and SCL activity showed significant changes in relation to stress but with no differential effect between experimental groups. Patients with IBS exhibit sustained HPA axis activity, and an increase in problematic GI symptoms in response to acute experimental psychosocial stress. These data pave the way for future interventional studies aimed at identifying novel therapeutic approaches to modulate the HPA axis and GI symptom response to acute psychosocial stress in IBS.

    Epithelial gaps created by shedding of epithelial cells in the small intestine can be visualized by using confocal laser endomicroscopy (CLE). The density of epithelial gaps in the small bowels of patients with inflammatory bowel disease (IBD) and controls without IBD is unknown. To determine whether the epithelial gap density in patients with IBD is different from that in controls. Prospective, controlled, cohort study. A tertiary-care referral center. This study involved patients with IBD and control patients without IBD undergoing colonoscopy. Probe-based CLE (pCLE) was used to image the terminal ileum. The primary outcome of the study was gap density, defined as the total number of gaps per 1000 cells counted in adequately imaged villi by using pCLE. The pCLE images were blindly reviewed, and the number of epithelial gaps and cells were manually counted. The secondary outcomes were correlation of gap density with disease activity, location, and severity of clinical disease. There were 30 controls and 28 patients with IBD. Of the patients with IBD, 16 had Crohn's disease, and 12 had ulcerative colitis. The median epithelial gap densities for controls and patients with IBD were 18 and 61 gaps/1000 cells, respectively (P < .001). Gap density did not correlate with disease activity. Patients with ulcerative pan-colitis tended toward gap densities lower than those of patients with limited colitis (32 versus 97 gaps/1000 cells, P = .06). Patients with IBD with severe clinical disease also had lower median gap densities (37 vs 90 gaps/1000 cells, P = .04). A single-center study. The epithelial gap density was significantly increased in patients with IBD compared with controls. ( NCT00988273.). Copyright © 2011. Published by Mosby, Inc.

    Hirotada Kittaka

    Full Text Available BACKGROUND: The level of intestinal fatty acid-binding protein (I-FABP is considered to be useful diagnostic markers of small bowel ischemia. The purpose of this retrospective study was to investigate whether the serum I-FABP level is a predictive marker of strangulation in patients with small bowel obstruction (SBO. METHODS: A total of 37 patients diagnosed with SBO were included in this study. The serum I-FABP levels were retrospectively compared between the patients with strangulation and those with simple obstruction, and cut-off values for the diagnosis of strangulation were calculated using a receiver operating characteristic curve. In addition, the sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV were calculated. RESULTS: Twenty-one patients were diagnosed with strangulated SBO. The serum I-FABP levels were significantly higher in the patients with strangulation compared with those observed in the patients with simple obstruction (18.5 vs. 1.6 ng/ml p<0.001. Using a cut-off value of 6.5 ng/ml, the sensitivity, specificity, PPV and NPV were 71.4%, 93.8%, 93.8% and 71.4%, respectively. An I-FABP level greater than 6.5 ng/ml was found to be the only independent significant factor for a higher likelihood of strangulated SBO (P =  0.02; odds ratio: 19.826; 95% confidence interval: 2.1560 - 488.300. CONCLUSIONS: The I-FABP level is a useful marker for discriminating between strangulated SBO and simple SBO in patients with SBO.

    In a Swedish celiac disease screening study (Exploring the Iceberg of Celiacs in Sweden), we systematically reviewed the clinical diagnostic procedures with the aim to evaluate the diagnostic accuracy and to take advantage of lessons learned for improving diagnostic routines. A school-based celiac disease screening study involving 5 Swedish centers, with 10,041 invited 12-year-olds with 7567 consenting participation. All 192 children with elevated serological markers were recommended to undergo small-bowel biopsy, performed and evaluated according to local clinical routines. All of the mucosal specimens were reevaluated by 1 and, when needed, 2 expert pathologists to reach diagnostic consensus. Small-bowel biopsies were performed in 184 children: 130 by endoscopy and 54 by suction capsule. Endoscopic biopsies were inconclusive in 0.6%, compared with 7.4% of biopsies by suction capsule. A patchy enteropathy was found in 9.1%. Reevaluation by the expert pathologist resulted in 6 additional cases with celiac disease and 1 cleared. Sixteen children with normal or inconclusive biopsies, 4 after endoscopy, and 12 after suction capsule were endoscopically rebiopsied, resulting in another 8 cases. The celiac disease prevalence of 30 of 1000 (95% confidence interval 26-34) was not statistically different from that previously reported. The present review revealed the importance of controlling each step of the diagnostic procedure. Several cases would have been missed by relying only on local routines. To improve the quality of childhood celiac disease diagnostics, we recommend multiple endoscopic biopsies from both proximal and distal duodenum and standardized evaluation by a pathologist with good knowledge of celiac disease.

    It is established that substance P (SP) is released by stimulation of nonadrenergic noncholinergic (NANC) excitatory nerves and vasoactive intestinal peptide (VIP) by stimulation of NANC inhibitory nerves. To evaluate the function of peptidergic nerves such as SP and VIP in small-bowel isografts, we examined the enteric nerve responses to SP and VIP in the isografted rat jejunum, using the normal rat jejunum as a control. Orthotopic entire small bowel transplantation (SBT) with portocaval drainage was performed from Lewis rats to Lewis rats. Grafted tissue specimens were obtained 130 days after SBT (n = 9). As controls, normal segments of the jejunum were obtained from untransplanted Lewis rats (n = 22). A mechanograph was used to evaluate in vitro jejunal responses to electrical field stimulation of the enteric nervous system before and after treatments with various autonomic nerve blockers and neuropeptides (SP and VIP). SP concentration-dependently mediated the contraction reaction of NANC excitatory nerve in the isografted jejunum and to a lesser extent in the normal jejunum. In addition, there were significant diferences in the percentages showing contraction at 1 x 10(-8) and 1 x 10(-6)g/mL SP between the normal and isografted jejunal muscle strips (P P < .01). Contraction reactions of SP were observed in both the normal and isografted jejunum but were increased in the isografted jejunum. Relaxation reactions of VIP were also observed in both the normal and isografted jejunum but were decreased in the isografted jejunum. The increase of the effects of SP via NANC excitatory nerves and the decrease of the effects of VIP in mediating NANC inhibitory nerves may be largely related to the peristaltic abnormalities seen in the isografted LEW rat jejunum.

Although initial data showed that use of this device is safe and free from serious complications, we report for the first time the successful management of an Elipse™ IGB-related adverse event. Presentation of case: A 41-year-old woman presented to our emergency department following two days of abdominal pain, vomiting, and constipation. Her medical history included four caesarean sections and insertion of the Elipse™ IGB 16 weeks prior to presentation. The patient was vitally stable at presentation and abdominal examination revealed a mildly distended abdomen. Plain X-ray revealed a small bowel obstruction (SBO, and a double contrast computed tomography scan showed a dilated small bowel with mild free fluid proximal to a transition zone at the distal jejunum. Laparoscopic enterotomy was performed just proximal to the obstruction site, and the balloon was visualized and extracted after it had been incised and emptied. The enterotomy incision was closed with an intracorporeal continuous absorbable suture. The patient’s recovery was uneventful and she was discharged on postoperative day 4. Discussion: We discuss the possible etiologies of SBO following Elipse™ IGB insertion, and present a brief literature review regarding surgical and nonsurgical management options for such cases. Conclusion: Although initial data showed the Elipse™ IGB to be safe, complications can occur and be managed successfully. Keywords: Elipse, Intragastric balloon, Capsule, Obesity, Case report

    AIM: To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm (AAA) repair surgery. METHODS: Nine patients (aged 35-78 years; body mass index (BMI) range: 23-36 kg/m2) post-surgery for AAA repair, and seven healthy control subjects (20-50 years; BMI range: 21-29 kg/m2) were studied. Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding (Nutrison®). Recordings were analyzed for the frequency, origin, length of migration, and direction of small intestinal burst activity. Lipid absorption was assessed on the first day and the third day post surgery in a subset of patients using the 13C-triolein-breath test, and compared with healthy controls. Subjects received a 20-min intraduodenal infusion of 50 mL liquid feed mixed with 200 μL 13C-triolein. End-expiratory breath samples were collected for 6 h and analyzed for 13CO2 concentration. RESULTS: The frequency of burst activity in the proximal and distal small intestine was higher in patients than in healthy subjects, under both fasting and fed conditions (P < 0.005). In patients there was a higher proportion of abnormally propagated bursts (71% abnormal), which began to normalize by d 3 (25% abnormal) post-surgery. Lipid absorption data was available for seven patients on d 1 and four patients on d 3 post surgery. In patients, absorption on d 1 post-surgery was half that of healthy control subjects (AUC 13CO2 1 323 ± 244 vs 2 646 ±365; P < 0.05, respectively), and was reduced to the one-fifth that of healthy controls by d 3 (AUC 13CO2 470 ± 832 vs 2 646 ± 365; P < 0.05, respectively). CONCLUSION: Both proximal and distal small intestinal motor activity are transiently disrupted in critically ill patients immediately after major surgery, with abnormal motility patterns extending as far as the ileum. These motor disturbances may contribute to impaired absorption

    Full Text Available Background: Supra-Transumbilical Laparotomy (STL has been used in paediatric surgery for a broad spectrum of abdominal procedures. We report our experience with STL approach for small bowel atresia repair in newborns and review previous published series on the topic. Patients and Methods: Fourteen patients with small bowel atresia were treated via STL approach at our Institution over a 5-year period and their charts were retrospectively reviewed. Results: STL procedure was performed at mean age of 3.1 day. No malrotation disorders were detected with pre-operative contrast enema. Eight patients (54.1% presented jejunal atresia, five (35.7% ileal atresia, and one (7.1% multiple ileal and jejunal atresias. Standard repair with primary end-to-back anastomosis was performed in all but one patient. In the newborn with multiple atresia, STL incision was converted in supra-umbilical transverse incision due to difficulty of exposition. After surgery, one patient developed anastomotic stricture, and another developed occlusion due to adhesions: Both infants required second laparotomy. No infections of the umbilical site were recorded, and cosmetic results were excellent in all patients. Conclusions: Increasing evidence suggests that STL approach for small bowel atresia is feasible, safe and provides adequate exposure for small bowel atresia surgery. When malrotation and colonic/multiple atresia are pre-operatively ruled out, STL procedure can be choosen as first approach.

    Full Text Available Myasthenia gravis is a chronic autoimmune disease affecting voluntary skeletal muscles. The altered sensitivity of acetylcholine receptors to muscle relaxants and concomitant treatment with anticholinesterase in these patients affect their anaesthetic management. Patients who have undergone bowel anastomosis and are on regular anticholinesterase treatment are susceptible to anastomotic leaks. We report successful anaesthetic management of class I myasthenic patient with coexisting small bowel intussusception operated for jejuno-ileal anastomoses using regional, inhalational and intravenous (i.v anaesthesia based on train of four responses, and avoiding the use of reversal (anticholinesterase.

    The use of an electromagnetic placement device (EMPD) can allow trained clinicians to safely perform small-bowel feeding tube (SBFT) placement at the bedside. Before initiation of enteral nutrition, most facilities require a radiology confirmation of tube placement. Requirement of X-ray confirmation delays the start of nutrition and leads to increased costs and utilization of resources. The purpose of this study was to determine the rate of agreement between clinician interpretation of SBFT placement using the EMPD images and X-ray confirmation on tip of SBFT placement. This single-center, retrospective, observational study used data completed by registered dietitians or registered nurses after SBFT placement and compared it with radiology reports in the electronic health record. All tube placements were performed using the EMPD and were determined to be in 1 of 4 locations: stomach, duodenum, at the ligament of Trietz, or not specified within the small bowel. A total of 280 tube placements were analyzed. When differentiating between stomach and small bowel, the rate of agreement using a κ statistic was substantial agreement (κ = 0.67) and when determining tip-of-tube location within the small bowel excluding not specified locations, there was almost perfect agreement with a κ = 0.93 and n = 84. These findings suggest that EMPD images provide substantial agreement with X-ray confirmation and almost perfect agreement when the tip of the tube is within the small bowel. This indicates that the EMPD could be used without X-ray confirmation. © 2018 American Society for Parenteral and Enteral Nutrition.

    Full Text Available We present the case of a 68-year-old female patient who was diagnosed with cancer of the descending colon in July 1994 and underwent partial resection of the colon (type 2, moderately to well differentiated adenocarcinoma, se, ly1, v1, n(–. In April 1996, she was admitted to a nearby hospital for symptoms of ileus, which improved at the hospital. However, she was referred to our hospital for melena. In blood test, Hb was 8.7 g/dl, showing anemia, and carcinoembryonic antigen level was elevated to 50.7 ng/ml. Abdominal CT and small bowel series showed only mild expansion of the small bowel, suggesting no obvious occlusion. Abdominal surgery was performed in May 1995 for repeated development of ileus symptoms and suspicion of bleeding from the small bowel. Since the findings of the abdominal surgery showed a circular tumor in the lower ileum, partial resection of the small bowel was performed. Histopathological examination showed type 3, moderately to well differentiated adnocarcinoma, se, ly2, v0, n = 1/13. The principal tumor was located within the subserosa and grew up exclusively through the muscularis propria and the submucosa, into the mucous layer. The mucosa remained slightly on the surface layer. Based on these findings, the patient was diagnosed with metastasis of descending colon cancer to the small bowel. Her prognosis was good, and neither metastasis nor redevelopment of the cancer have been confirmed to date, 11 years and 7 months since the surgery.

  10. Acute Abdomen and Perforated Bowel with a Rare Pathology: Nonfamilial Visceral Myopathy

    Full Text Available Visceral myopathy is a rare chronic disease affecting the peristalsis of the bowel causing intermittent pseudoobstruction. We report an atypical case of an eighty-nine-year-old woman with no prior history of abdominal illness who was admitted to our hospital with 2 days of increasing nausea, abdominal distension, and abdominal pain. On arrival at the hospital, she was critically ill. Abdominal X-ray showed distended loops of the colon and liquid levels resembling colonic obstruction. A subsequent abdominal CT scan confirmed the colonic obstruction. A suspicion of sigmoid volvulus was raised, that is why a barium enema was performed but no lower colonic obstruction could be confirmed. Acute laparotomy showed perforated cecum without intestinal obstruction. Postoperatively, the patient became septic which was fatal for the patient. Pathology gave the diagnosis visceral myopathy. It is very difficult to make the diagnosis clinically and radiologically since visceral myopathy mimics other more common gastrointestinal diseases. It is important to consider visceral myopathy as a possible diagnosis in cases with recurrent episodes of abdominal pain, vomiting, and abdominal distension, but without actual intestinal obstruction.

    An increased risk of small bowel carcinoma [SBC] has been reported in coeliac disease [CD] and Crohn's disease [CrD]. We explored clinico-pathological, molecular, and prognostic features of CD-associated SBC [CD-SBC] and CrD-associated SBC [CrD-SBC] in comparison with sporadic SBC [spo-SBC]. A total of 76 patients undergoing surgical resection for non-familial SBC [26 CD-SBC, 25 CrD-SBC, 25 spo-SBC] were retrospectively enrolled to investigate patients' survival and histological and molecular features including microsatellite instability [MSI] and KRAS/NRAS, BRAF, PIK3CA, TP53, HER2 gene alterations. CD-SBC showed a significantly better sex-, age-, and stage-adjusted overall and cancer-specific survival than CrD-SBC, whereas no significant difference was found between spo-SBC and either CD-SBC or CrD-SBC. CD-SBC exhibited a significantly higher rate of MSI and median tumour-infiltrating lymphocytes [TIL] than CrD-SBC and spo-SBC. Among the whole SBC series, both MSI─which was the result of MLH1 promoter methylation in all but one cases─and high TIL density were associated with improved survival at univariable and stage-inclusive multivariable analysis. However, only TILs retained prognostic power when clinical subgroups were added to the multivariable model. KRAS mutation and HER2 amplification were detected in 30% and 7% of cases, respectively, without prognostic implications. In comparison with CrD-SBC, CD-SBC patients harbour MSI and high TILs more frequently and show better outcome. This seems mainly due to their higher TIL density, which at multivariable analysis showed an independent prognostic value. MSI/TIL status, KRAS mutations and HER2 amplification might help in stratifying patients for targeted anti-cancer therapy. Copyright © 2017 European Crohn’s and Colitis Organisation (ECCO).

    2010-02-01

    Full Text Available Abstract Background Small intestinal bacterial overgrowth (SIBO is a condition in which excessive levels of bacteria, mainly the colonic-type species are present in the small intestine. Recent data suggest that SIBO may contribute to the pathophysiology of Irritable bowel syndrome (IBS. The purpose of this study was to identify potential predictors of SIBO in patients with IBS. Methods Adults with IBS based on Rome II criteria who had predominance of bloating and flatulence underwent a glucose breath test (GBT to determine the presence of SIBO. Breath samples were obtained at baseline and at 30, 45, 60, 75 and 90 minutes after ingestion of 50 g of glucose dissolved in 150 mL of water. Results of the glucose breath test, which measures hydrogen and methane levels in the breath, were considered positive for SIBO if 1 the hydrogen or methane peak was >20 ppm when the baseline was Results Ninety-eight patients were identified who underwent a GBT (mean age, 49 y; 78% female. Thirty-five patients (36% had a positive GBT result suggestive of SIBO. A positive GBT result was more likely in patients >55 years of age (odds ratio [OR], 3.6; 95% confidence interval [CI], 1.4-9.0 and in females (OR, 4.0; 95% CI, 1.1-14.5. Hydrogen was detected more frequently in patients with diarrhea-predominant IBS (OR, 8; 95% CI, 1.4-45, and methane was the main gas detected in patients with constipation-predominant IBS (OR, 8; 95% CI, 1.3-44. There was no significant correlation between the presence of SIBO and the predominant bowel pattern or concurrent use of tegaserod, proton pump inhibitors, or opiate analgesics. Conclusions Small intestinal bacterial overgrowth was present in a sizeable percentage of patients with IBS with predominance of bloating and flatulence. Older age and female sex were predictors of SIBO in patients with IBS. Identification of possible predictors of SIBO in patients with IBS could aid in the development of successful treatment plans.

    To evaluate the long-term function and effective motility of a reversed jejunal segment after extensive small bowel resection, the authors continuously measured postoperative bowel motility during interdigestive and postprandial periods in conscious dogs 6 to 10 months after surgery. The long-term findings were compared with previously reported short-term results measured 2 to 4 weeks after the operation. In the long-term follow-up dogs with a 20-cm reversed jejunal segment constructed after extensive (75% to 80%) small bowel resection, the fasting duodenal migrating myoelectric (or motor) complex (MMC) was often interrupted in the jejunum above the reversed segment, and did not migrate smoothly to the reversed segment or terminal ileum. The MMCs arising from the duodenum predominantly propagated to the ileum through the inherent anatomic continuity of the bowel. In addition, brief small discordant contractions were frequent in the reversed segment and the jejunum, above the proximal anastomosis. These findings are similar to those of the MMC propagation pattern noted 2 to 4 weeks after surgery. However, the postprandial duration without duodenal MMC activity was significantly shorter in the dogs with long-term follow-up than in those with short-term follow-up (both were longer than in control dogs). Marked dilatation of the jejunum and reversed jejunal segment was noted across the proximal anastomosis. These results suggest that the transit time and passage of intestinal contents can be delayed and stagnated for at least 10 months after extensive small bowel resection with a 20-cm reversed jejunal segment.(ABSTRACT TRUNCATED AT 250 WORDS)

    AIM: To investigate the prevalence of proximal small bowel (SB) lesions detected by wireless capsule endoscopy (WCE) in Crohn’s disease (CD). METHODS: WCE was performed in 64 patients: 32 with CD of the distal ileum, and 32 controls with iron-deficiency anemia (IDA) or diarrhea. WCE was performed using the Given SB-WCE, followed by small intestine contrast ultrasonography (SICUS). Findings compatible with CD by using WCE included erosions, aphthoid or deep ulcers, and strictures/stenosis. RESULTS: WCE detected proximal SB lesions in 16/32 (50%) patients (14 aphthoid ulcers, 2 deep ulcers, one stricture), which appeared not to be related to clinical parameters [epigastric pain, age, smoking, non-steroidal anti-inflammatory drugs (NSAIDs), IDA]. Among patients with proximal SB lesions, 6 (37%) were smokers, 3 (19%) NSAID users, 3 (19%) had epigastric pain and 4 (25%) had IDA. SICUS detected proximal SB lesions in 3/32 patients (19%) also showing lesions with WCE. No correlations were observed between proximal SB lesions assessed by WCE or by SICUS (χ2 = 1.5, P = 0.2). CONCLUSION: The use of WCE allows the detection of previously unknown upper SB lesions in a high proportion of patients with a previous diagnosis of CD involving the distal ileum. PMID:20614486

    Therapeutic and diagnosis properties of radioactive gold nanoparticle (198-AuNPs) cause them to be suitable for detection and treatment of tumors. Electrical and optical properties of PEG-198AuNPs were examined in this paper. Polyethylene Glycol (PEG)-198 AuNPs can be used for treatment and diagnosis of small intestine tumors. Wireless fluorescence capsule endoscopy will be able to detect emission lights of triggered Au by external light. First, the output electrical field was calculated by DDSCAT software. Secondly, tumor and distribution of PEG-198 gold nanoparticles were modeled using Monte Carlo simulation and finally dose delivered throughout a solid tumor when the PEG-198 gold nanoparticles linked to each cell was calculated. Polyethylene Glycol functionalized gold nanoparticles (AuNPs) possess optimized sizes (30 nm core diameter and 70 nm hydrodynamic diameters) to target individual tumor cells. Surface distribution to receive doses of up to 50Gy was simulated.  Activities and absorbed doses by the tumors with 0.25cm and 0.5cm radius were 187.9mCi and 300mCi and 72 and 118 Gy,respectively. Therapeutic and diagnosis properties of 198-AuNPs show that it can be used for treatment and detection of small bowel tumors in early stage of growing.

    BACKGROUND: Crohn's disease can cause strictures throughout the gastrointestinal tract. Endoscopic balloon dilatation is a well-established treatment, but recurrence is seen in up to three out of four cases. Infliximab is playing an increasingly important role in the modern systemic treatment...... of severe Crohn's disease. Combining the anti-inflammatory effects of infliximab with the proven effect of endoscopic balloon dilatation could possibly improve outcome. In small studies, intralesional injections in perianal fistulas have been effective and endoscopic injection therapy in colonic strictures...... is feasible. OBJECTIVE: We wanted to assess whether serial intralesional injection of infliximab in small bowel strictures is feasible and reduces local inflammation. METHODS: We included six patients with Crohn's disease and inflammatory small bowel strictures. They were treated with endoscopic serial...

    Serotonin, a key denominator of the brain-gut axis is involved in the regulation of gastrointestinal function as well as cognition, mood and hypothalamic-pituitary-adrenal axis-mediated neuroendocrine responses. To assess the effects of an acutely increased serotonergic activity, using a 20 mg intravenous citalopram challenge test on visceral perception, affective memory performance, mood and neuroendocrine responses, respectively, in diarrhoea-predominant irritable bowel syndrome patients and controls. In a randomized, double-blind crossover design, 14 diarrhoea-predominant irritable bowel syndrome patients and 14 matched controls were studied under citalopram and placebo conditions, respectively. Visceral perception was scored in response to rectal distensions. Affective memory performance, mood, levels of adrenocorticotropic hormone, cortisol, prolactin and biochemical parameters of serotonergic metabolism were simultaneously assessed. Visceral perception did not significantly differ between the citalopram and placebo condition. Citalopram administration enhanced affective memory performance because of a bias towards positive material but no significant changes in mood. Citalopram significantly increased plasma serotonin, adrenocorticotropic hormone and cortisol levels compared with placebo. Citalopram did not differentially affect the patient or control group. We have provided evidence that acutely increased serotonergic activity influences neuroendocrine responses and cognition in diarrhoea-predominant irritable bowel syndrome and controls without a significant effect on visceral perception.

    The identification of developmental curve patterns generated by a simulation-based educational method and the variables that can accelerate the learning process will result in cost-effective training. This study describes the learning curves of a simulation-based instructional design (ID) that uses ex vivo animal models to teach laparoscopic latero-lateral small bowel anastomosis. Twenty general surgery residents were evaluated on their performance of laparoscopic latero-lateral jejuno-jejunal anastomoses (JJA) and gastro-jejunal anastomoses (GJA), using swine small bowel and stomach on an endotrainer. The ID included the following steps: (1) provision of references and videos demonstrating the surgical technique, (2) creation of an engaging context for learning, (3) critical review of the literature and video on the procedures, (4) demonstration of the critical steps, (5) hands-on practice, (6) in-action instructor's feedback, (7) quality assessment, (8) debriefing at the end of the session, and (9) deliberate and repetitive practice. Time was recorded from the beginning to the completion of the procedure, along with the presence or absence of anastomotic leaks. The participants needed to perform 23.8 ± 6.96 GJA (12-35) and 24.2 ± 6.96 JJA (9-43) to attain proficiency. The starting point of the learning curve was higher for the GJA than for the JJA, although the slope and plateau were parallel. Further, four types of learning curves were identified: (1) exponential, (2) rapid, (3) slow, and (4) no tendency. The type of pattern could be predicted after procedure number 8. These findings may help to identify the learning curve of a trainee early in the developmental process, estimate the number of sessions required to reach a performance goal, determine a trainee's readiness to practice the procedure on patients, and identify the subjects who lack the innate technical abilities. It may help motivated individuals to become reflective and self

    Small intestinal bacterial overgrowth and sugar malabsorption (lactose, fructose, sorbitol) may play a role in irritable bowel syndrome. The lactulose breath test is a reliable and non-invasive test for the diagnosis of small intestinal bacterial overgrowth. The lactose, fructose and sorbitol hydrogen breath tests are widely used to detect specific sugar malabsorption. To assess the extent to which small intestinal bacterial overgrowth may influence the results of hydrogen sugar breath tests in irritable bowel syndrome patients. We enrolled 98 consecutive irritable bowel syndrome patients. All subjects underwent hydrogen lactulose, lactose, fructose and sorbitol hydrogen breath tests. Small intestinal bacterial overgrowth patients were treated with 1-week course of antibiotics. All tests were repeated 1 month after the end of therapy. A positive lactulose breath test was found in 64 of 98 (65%) subjects; these small intestinal bacterial overgrowth patients showed a significantly higher prevalence of positivity to the lactose breath test (P fructose breath test (P fructose and sorbitol breath tests positivity (17% vs. 100%, 3% vs. 62%, and 10% vs. 71% respectively: P malabsorption misdiagnosis.

    Chronic intestinal pseudo-obstruction (CIPO) is a rare, serious motility disorder, with life-threatening complications over time. However, lack of an established, non-invasive diagnostic method has caused delays in the diagnosis of this intractable disease. Cine-magnetic resonance imaging (MRI) is an emerging technique, with a potential to evaluate the motility of the entire bowel. We compared small bowel motility in healthy volunteers, patients with irritable bowel syndrome (IBS), and those with CIPO, using cine-MRI, and evaluated the usefulness of cine-MRI as a novel diagnostic method for CIPO. Twelve healthy volunteers, IBS patients, and CIPO patients prospectively underwent cine-MRI at 1.5 T. Luminal diameter, contraction ratio, and contraction cycle were measured and compared between the groups. Cine-MRI provided sufficient dynamic images to assess the motility of the entire small bowel. Luminal diameter (mean±s.d.) in CIPO patients was significantly higher than that in healthy volunteers and IBS patients (43.4±14.1, 11.1±1.5, and 10.9±1.9 mm, respectively), and contraction ratio was significantly lower in CIPO patients than that in healthy volunteers and IBS patients (17.1±11.0%, 73.0±9.3%, and 74.6±9.4%, respectively). No significant differences were observed in the contraction cycle. This study is the first to assess the clinical utility of cine-MRI in CIPO patients. Cine-MRI clearly detected contractility impairments in CIPO patients. Cine-MRI is noninvasive, radiation-free, and can directly evaluate the entire small bowel peristalsis, and can detect the affected loops at a glance; therefore, it might be extremely useful for the diagnosis and follow-up of CIPO patients in clinical practice.

    Diffuse disturbance in gastrointestinal motility may be present in patients with irritable bowel syndrome (IBS). To further investigate small intestinal motility in IBS patients small intestinal transit time (SITT) was determined and related to the symptom status. 11 female patients with IBS (mean age 29 years) were divided into those whose predominate symptom was diarrhea (N=6), and those with only constipation (N=5). All subjects ingested an isosmotic solution of lactulose (10 gm in 150cc of water) labeled with 99m-Tc-DTPA (Sn). The patient was studied supine under a 25 inch gamma camera with data collected at 1 frame per minute for 180 minutes or until activity appeared in the ascending colon. Regions of interest were selected over the cecum and ascending colon. The time of first appearance of radioactivity in the region of the cecum was taken as the small intestinal transit time. SITT in the 5 normal females was 98.7 +- 13 min (mean +- SEM). SITT in the IBS patients with diarrhea, 67.3 +- 7 min was significantly faster (p< 0.08). SITT in the constipated IBS patients, 126 +- 12 min, was slower than normals and significantly different from diarrhea patients (p< 0.001). These studies show that IBS patients with diarrhea have significantly faster SITT than normals while constipated IBS patients have significantly slower SITT than the diarrhea subgroup. Further, this study emphasizes the need to study the various symptomatic subgroups of IBs patients independently and indicates a possible role for abnormal SITT in the pathogenesis of IBS

    The authors report a case of a non-Hodgkin lymphoma of the small bowel, presenting with ulcerative lesions on radiological studies. primary intestinal lymphoma is considered a rare entity and its diagnosis criteria are quiet strict. The secondary form of the disease - involvement of the small bowel by systemic lymphoma - constitutes an infrequent clinical presentation of these neoplasms and must be considered when the criteria for primary disease are not fulfilled. Diagnosis is based on small bowel series studies and/or computed tomography findings, but the definitive diagnosis is established by biopsy. (author)

    Isolated organs proofed to be a robust tool to study effects of (potential) therapeutics in organophosphate poisoning. Small bowel samples have been successfully used to reveal smooth muscle relaxing effects. In the present study, the effects of obidoxime, TMB-4, HI-6 and MB 327 were investigated on human small bowel tissue and compared with rat data. Hereby, the substances were tested in at least seven different concentrations in the jejunum or ileum both pre-contracted with carbamoylcholine. Additionally, the cholinesterase activity of native tissue was determined. Human small intestine specimens showed classical dose response-curves, similar to rat tissue, with MB 327 exerting the most potent smooth muscle relaxant effect in both species (human EC 50 =0.7×10 -5 M and rat EC 50 =0.7×10 -5 M). The AChE activity for human and rat samples did not differ significantly (rat jejunum=1351±166 mU/mg wet weight; rat ileum=1078±123 mU/mg wet weight; human jejunum=1030±258 mU/mg wet weight; human ileum=1293±243 mU/mg wet weight). Summarizing, our isolated small bowel setup seems to be a solid tool to investigate the effects of (potential) therapeutics on pre-contracted smooth muscle, with data being transferable between rat and humans.

    Full Text Available Abstract Background Due to the restrictive nature of a gluten-free diet, celiac patients are looking for alternative therapies. While drug-development programs include gluten challenges, knowledge regarding the duration of gluten challenge and gluten dosage is insufficient. We challenged adult celiac patients with gluten with a view to assessing the amount needed to cause some small-bowel mucosal deterioration. Methods Twenty-five celiac disease adults were challenged with low (1-3 g or moderate (3-5g doses of gluten daily for 12 weeks. Symptoms, small-bowel morphology, densities of CD3+ intraepithelial lymphocytes (IELs and celiac serology were determined. Results Both moderate and low amounts of gluten induced small-bowel morphological damage in 67% of celiac patients. Moderate gluten doses also triggered mucosal inflammation and more gastrointestinal symptoms leading to premature withdrawals in seven cases. In 22% of those who developed significant small- intestinal damage, symptoms remained absent. Celiac antibodies seroconverted in 43% of the patients. Conclusions Low amounts of gluten can also cause significant mucosal deterioration in the majority of the patients. As there are always some celiac disease patients who will not respond within these conditions, sample sizes must be sufficiently large to attain to statistical power in analysis.

    Small bowel transplantation (SBT) can be a life-saving medical procedure. However, these recipients experience high risk of bloodstream infections caused by Candida. This research aims to characterise the SBT recipient gut microbiota over time following transplantation and investigate the epidemiology of candidaemia in seven paediatric patients. Candida species from the recipients' ileum and bloodstream were identified by internal transcribed spacer sequence and distinguished to strain by multilocus sequence typing and randomly amplified polymorphic DNA. Antifungal susceptibility of bloodstream isolates was determined against nine antifungals. Twenty-two ileostomy samples harboured at least one Candida species. Fungaemia were caused by Candida parapsilosis, Candida albicans, Candida glabrata, Candida orthopsilosis and Candida pelliculosa. All but three bloodstream isolates showed susceptibility to all the antifungals tested. One C. glabrata isolate showed multidrug resistance to itraconazole, amphotericin B and posaconazole and intermediate resistance to caspofungin. Results are congruent with both endogenous (C. albicans, C. glabrata) and exogenous (C. parapsilosis) infections; results also suggest two patients were infected by the same strain of C. parapsilosis. Continuing to work towards a better understanding of sources of infection-particularly the exogenous sources-would lead to targeted prevention strategies. © 2017 Blackwell Verlag GmbH.

    Objective: To develop a method of measuring small bowel transit time (SBTT) by 99 Tc m -sulfur collide (SC) imaging and to compare with the method of added lactose in the test meal. Methods: 20 healthy volunteers and 26 patients with gastrointestinal disorders were studied. In fasting state, the subjects were asked to ingest the 99 Tc m -SC labelled solid meal within 5 minutes, then the image acquisition was immediately started with SPECT. The images were acquired every 15 min during the first hour, at 30 min intervals during 2∼4 hours and hourly thereafter until 80% radioactivity had entered the colon. One week later, the same procedure of imaging with 15 g lactulose added in the test meal was performed. The regions of interest (ROIs) were taken at stomach and colon, and the SBTT was calculated by deconvolution or by subtraction of the 50% time of gastric emptying from the 50% time of colon filling. Results: 1) The mean SBTT of 20 healthy volunteers was (4.2 +- 0.5) h, oral-caecum transit time (OCTT) was (4.3 +- 0.6) h; lactulose shortened the SBTT by (1.8 +- 0.6) h; 2) 26 patients showed different results of SBTT due to their different gastrointestinal disorders bases. Conclusions: 99 Tc m -SC imaging was a noninvasive and useful method to measure SBTT. The added lactulose can shorten the examination time and help to identify the time of food to the ileocecal region

    To evaluate the value of deep small-bowel endoscopy (DSBE) in the diagnosis of Crohns disease (CD). The endoscopic and clinical data of 54 patients with CD receiving capsule endoscopy (CE) and double-balloon enteroscopy (DBE) between January, 2004 and December, 2008 were summarized and analyzed retrospectively. The main indications for DSBE in our series were suspected CD (42.6%) and obscure gastrointestinal bleeding (25.9%). DSBE was obviously superior to barium imaging. The detection rate of CD was significantly higher with DSBE (92.6%) than with ileocolonoscopy (75.9%, P=0.017), and DSBE provides much more detailed descriptions of specific endoscopic features such as segmental distribution and lumen changes. DSBE significantly improve the diagnostic efficiency, giving priority to offer a guide and raise suspected diagnosis for CD. DSBE is a valuable modality for detecting CD lesions in the jejunum and ileum and for evaluating lesion involvement and severity. The combination with a comprehensive analysis of routine imaging findings, gastro endoscopy, and clinical data can further enhance the diagnostic efficiency of DSBE.

    Every single imaging finding that can be disclosed on conventional and MR enteroclysis was correlated with the Crohn's disease activity index (CDAI). Nineteen consecutive patients with Crohn's disease underwent colon endoscopy and both conventional and MR enteroclysis examinations. Seventeen MR imaging findings and seven conventional enteroclysis findings were ranked on a four-point grading scale and correlated with CDAI, with a value of 150 considered as the threshold for disease activity. Six patients had active disease in the colon according to colon endoscopy. In the remaining 13 patients, the presence of deep ulcers (P=0.002), small bowel wall thickening (P=0.022) and gadolinium enhancement of mesenteric lymph nodes (P=0.014) identified on MR enteroclysis images were strongly correlated to disease activity. The product of deep ulcers and enhancement of lymph node ranks identified on MR enteroclysis were the optimum combination for discriminating active from non-active disease (F-test: 55.95, P<0.001). Additionally, the ranking of deep ulcers on conventional enteroclysis provided statistically significant differences between active and non-active patients (F-test: 14.12, P=0.004). Abnormalities strongly suggestive of active Crohn's disease can be disclosed on MR enteroclysis examinations and may provide pictorial information for local inflammatory activity. (orig.)

    The aim of this study was to determine the feasibility of cine magnetic resonance imaging (MRI) for diagnosing strangulated small bowel obstruction (SBO). This study included 38 patients with clinically confirmed SBO who had undergone cine MRI. Cine MRI scans were evaluated regarding the presence of the 'peristalsis gap sign' (referring to an akinetic or severely hypokinetic closed loop), indicating strangulation. Computed tomography (CT) was performed in 34 of 38 patients with (n=25) or without (n=9) contrast enhancement. CT images were evaluated using a combination of criteria (presence of hyperattenuation, poor contrast enhancement, mesenteric edema, wall thickening, massive ascites) indicating strangulation. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of cine MRI and CT for the diagnosis of strangulation were calculated and compared using surgical findings and the clinical course as the reference standard. Sensitivity, specificity, PPV, and NPV of cine MRI were 100%, 92.9%, 83.3%, and 100%, respectively; and those of CT (of which 26.5% was performed without contrast enhancement) were 66.7%, 92.0%, 75.0%, and 88.5%, respectively. There was no significant difference in diagnostic accuracy between the two methods (P=0.375). Cine MRI is a feasible and promising technique for diagnosing strangulation. (author)

    For patients with small bowel obstruction (SBO), surgical care has been associated with improved outcomes; however, it remains unknown how it impacts satisfaction. Patients admitted for SBO who completed the hospital satisfaction survey were eligible. Only those with adhesions or hernias were included. Chart review extracted structural characteristics and outcomes. Forty-seven patients were included; 74% (n = 35) were admitted to a surgical service. Twenty-six percent of the patients (n = 12) were admitted to medicine, and 50% of those (n = 6) had surgical consultation. Patients with surgical involvement as the consulting or primary service (SURG) had higher satisfaction with the hospital than those cared for by the medical service (MED) (80% SURG, 33% MED, P = .015). SURG patients also had higher satisfaction with physicians (74% SURG, 44% MED, P = .015). Surgical involvement during SBO admissions is associated with increased patient satisfaction, and adds further weight to the recommendation that these patients be cared for by surgeons.

    To estimate the prevalence of small intestinal bacterial overgrowth (SIBO) in our geographical area (Western Sicily, Italy) by means of an observational study, and to gather information on the use of locally active, non-absorbable antibiotics for treatment of SIBO. Our survey included 115 patients fulfilling the Rome II criteria for diagnosis of irritable bowel syndrome (IBS); a total of 97 patients accepted to perform a breath test with lactulose (BTLact), and those who had a positive test, received Rifaximin (Normix, Alfa Wassermann) 1200 mg/d for 7 d; 3 wk after the end of treatment, the BTLact was repeated. Based on the BTLact results, SIBO was present in about 56% of IBS patients, and it was responsible for some IBS-related symptoms, such as abdominal bloating and discomfort, and diarrhoea. 1-wk treatment with Rifaximin turned the BTLact to negative in about 50% of patients and significantly reduced the symptoms, especially in those patients with an alternated constipation/diarrhoea-variant IBS. SIBO should be always suspected in patients with IBS, and a differential diagnosis is done by means of a "breath test". Rifaximin may represent a valid approach to the treatment of SIBO.

    The objective of this study was to investigate early postoperative inflammatory small bowel obstruction (EPISBO) by applying gastrointestinal decompression to relieve abdominal distension. Thirty-six cases of patients were randomly divided into two groups: a control group (20 cases) and an observation group (16 cases). Routine continuous gastrointestinal decompression was assigned to the control group, while gastrointestinal decompression with dynamic and profound adjustment of the gastric tube and abdomen movement was assigned to the observation group, to induce abundant gastric juice and gas, and significantly relieve abdominal distension. A test was performed for each of the two groups to observe the relief time of the abdominal distension and the difference of abdominal girth of 5 cm before and after gastrointestinal decompression. Compared with the control group, the patients in the observation group with abdominal distension had earlier pain relief. More patients in the observation group had a difference of abdominal girth of 5 cm before and after gastrointestinal decompression. In gastrointestinal decompression, the method of dynamic and profound adjustment of the gastric tube and abdomen movement improve the effect of the gastrointestinal decompression, which relieves abdominal distention and promotes the postoperative recovery of organ functions.

    AIM: To evaluate the safety and effectiveness of laparoscopy compared with laparotomy for diagnosing and treating small bowel injuries (SBIs) in a porcine model. METHODS: Twenty-eight female pigs were anesthetized and laid in the left recumbent position. The SBI model was established by shooting at the right lower quadrant of the abdomen. The pigs were then randomized into either the laparotomy group or the laparoscopy group. All pigs underwent routine exploratory laparotomy or laparoscopy to evaluate the abdominal injuries, particularly the types, sites, and numbers of SBIs. Traditional open surgery or therapeutic laparoscopy was then performed. All pigs were kept alive within the observational period (postoperative 72 h). The postoperative recovery of each pig was carefully observed. RESULTS: The vital signs of all pigs were stable within 1-2 h after shooting and none of the pigs died from gunshot wounds or SBIs immediately. The SBI model was successfully established in all pigs and definitively diagnosed with single or multiple SBIs either by exploratory laparotomy or laparoscopy. Compared with exploratory laparotomy, laparoscopy took a significantly longer time for diagnosis (41.27 ± 12.04 min vs 27.64 ± 13.32 min, P = 0.02), but the time for therapeutic laparoscopy was similar to that of open surgery. The length of incision was significantly reduced in the laparoscopy group compared with the laparotomy group (5.27 ± 1.86 cm vs 15.73 ± 1.06 cm, P surgery, both laparotomy and laparoscopy offered a definitive diagnosis with no missed injuries. Postoperative complications occurred in four cases (three following laparotomy and one following laparoscopy, P = 0.326). The average recovery period for bowel function, vital appearance, and food re-intake after laparoscopy was 10.36 ± 4.72 h, 14.91 ± 3.14 h, and 15.00 ± 7.11 h, respectively. All of these were significantly shorter than after laparotomy (21.27 ± 10.17 h, P = 0.004; 27.82 ± 9.61 h, P laparotomy

  16. The small intestine and irritable bowel syndrome (IBS): a batch process model.

    Dobson, Brian C

    2008-11-01

    Faults in a batch process model of the small intestine create the symptoms of all types of irritable bowel syndrome. The model has three sequential processing sections corresponding to the natural divisions of the intestine. It is governed by a brain controller that is divided into four sub-controllers, each with a unique neurotransmitter. Each section has a sub-controller to manage transport. Sensors in the walls of the intestine provide input and output goes to the muscles lining the walls of the intestine. The output controls the speed of the food soup, moves it in both directions, mixes it, controls absorption, and transfers it to the next section at the correct speed (slow). The fourth sub-controller manages the addition of chemicals. It obtains input from the first section of the process via the signalling hormone Cholecystokinin and sends output to the muscles that empty the gall bladder and pancreas. The correct amounts of bile salts and enzymes are then added to the first section. The sub-controllers produce output only when input is received. When output is missing the enteric nervous system applies a default condition. This default condition normally happens when no food is in the intestine. If food is in the intestine and a transport sub-controller fails to provide output then the default condition moves the food soup to the end of that section. The movement is in one direction only (forward), at a speed dependent on the amount and type of fibre present. Cereal, bean and vegetable fibre causes high speeds. This default high speed transport causes irritable bowel syndrome. A barrier is created when a section moving fast at the default speed, precedes a section controlled by a transport sub-controller. Then the sub-controller constricts the intestine to stop the fast flow. The barrier causes constipation, cramping, and bloating. Diarrhoea results when the section terminating the process moves at the fast default speed. Two problems can occur to prevent

    Impaired intestinal integrity, including increased permeability of the small bowel mucosa, has been shown in patients with celiac disease (CD) as well as with type 1 diabetes (T1D). Zonulin (ZO, pre-haptoglobin), a tight junction regulator, plays a particular role in the regulation of intestinal barrier function and in the pathogenesis of the above-mentioned diseases. To investigate whether enteroviruses (EVs) and immunoregulatory cells are associated with intestinal permeability in patients with CD alone and with coexistent T1D. Altogether 80 patients (mean age 10.68 ± 6.69 years) who had undergone small bowel biopsy were studied. Forty patients with functional dyspepsia and normal small bowel mucosa formed the control group. The circulating ZO level in sera was evaluated using ELISA. The densities of EV, FOXP3+ regulatory T cells (Tregs), indoleamine 2,3-dioxygenase (IDO+) dendritic cells (DCs) and glutamic acid dexarboxylase (GAD)65+ cells in small bowel mucosa were investigated by immunohistochemistry. The expression analysis of FOXP3, tight junction protein 1 (TJP1), gap junction (GJA1), IDO and CD103 genes was evaluated by real-time PCR. The ZO level was higher in CD patients compared to subjects with a normal small bowel mucosa, particularly in those with Marsh IIIc atrophy (p = 0.01), and correlated with the density of EV (r = 0.63; p = 0.0003) and IDO+ DCs (r = 0.58; p = 0.01) in the small bowel mucosa. The density of GAD65+ epithelial cells was correlated with the density of EV (r = 0.59; p = 0.03) and IDO+ DCs (r = 0.78; p = 0.004) in CD patients. The relative expression of FOXP3 mRNA in the small bowel mucosa tissue was significantly higher in patients with CD, compared to subjects with a normal mucosa, and correlated with the density of EV (r = 0.62; p = 0.017) as well as with the relative expression of IDO mRNA (r = 0.54; p = 0.019). The CD is associated with elevation of the circulating ZO level, the value of which

    It was the intent of this study to define which, if any, radiographic observations corresponded with specific causes of diffuse infiltrative small bowel disease and if radiographic findings could differentiate inflammatory disease from neoplastic disease and either of them from normal. Bowel spasticity, luminal narrowing, and thumb printing tend to indicate the presence of tumor more often than inflammatory disease. Increased bowel gas in cats and barium adhesion in dogs and cats suggest that a component of enteritis is present. Decreased bowel gas in dogs is more often associated with obstructive disease, but is not helpful in differentiating diffuse inflammatory disease from diffuse neoplastic disease. While several observations that can foster differentiation of neoplastic from inflammatory disease were found, this study also indicated that the UGI lacks a high degree of predictive value other than to indicate the presence of infiltrative small bowel disease

  20. Angiotensin-Converting Enzyme Inhibitor-Induced Angioedema of the Small Bowel-A Surgical Abdomen Mimic.

    2015-06-01

    Angioedema is an infrequent complication of the use of angiotensin-converting enzyme inhibitors (ACEi) that has an incidence of up to 0.5%. The oropharynx is most commonly affected. Angioedema of the small bowel is a much rarer occurrence; it uniformly presents with abdominal pain of variable duration. A 51-year-old man presented to the emergency department (ED) with generalized abdominal pain, emesis, diarrhea, and bloating. Medical history was significant for hypertension and medications included captopril, metoprolol and aspirin. Vital signs and laboratory tests were unremarkable. Due to the presence of significant abdominal tenderness with guarding on examination, a FAST (focused assessment with ultrasound in trauma) examination was performed and revealed free fluid in the abdomen. A computed tomography scan of the abdomen was quickly obtained, which revealed a large amount of simple-appearing free fluid within the abdomen and mucosal edema throughout the small bowel. The patient underwent an emergent diagnostic laparoscopy and was ultimately diagnosed with angioedema of the small bowel, deemed secondary to captopril usage. Captopril was discontinued and symptoms gradually resolved with supportive care. When imaging is obtained in cases such as this one, small bowel submucosal edema and ascites are often present. Supportive care and cessation of ACEi usage are the cornerstones of treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In patients on ACEi, it is important to keep this diagnosis in mind to potentially avoid an unneeded surgical intervention, as the condition is self-limiting and can be treated primarily with supportive measures.

    During Roux-en-Y-gastric Bypass, the limb lengths are preoperatively determined regardless of individual small bowel length (SBL), which presents a great variability. Few studies highlighted anthropometric factors associated with SBL, and none attempted to predict SBL preoperatively. The aim of this study is to evaluate factors correlated to SBL (anthropometric and radiologic) and to establish a preoperative SBL prediction. In this single-center prospective study, 30 adult patients who underwent laparotomy with a preoperative CT scan were included. Intraoperative SBL measurement was performed with an umbilical tape. Anthropometric parameters were age, gender, height, and BMI. 2D radiological measurements consisted of subcutaneous thickness, abdominal diameters, waist circumference, and mesenteric root length. 3D radiological volumetric reconstructions consisted of whole small bowel and mesentery (WSBM), lean small bowel and mesentery (LSBM), and fat small bowel and mesentery (FSBM). Mean intraoperative measurement of SBL was 531 ± 105 cm. Among the clinical and radiological measurements, the FSBM volume presented the greatest dispersion. Height (p < 0.02) and LSBM volume (p < 0.01) were significantly correlated to the SBL in univariate analysis. LSBM volume was the only measurement significantly associated with SBL in multivariate analysis (p < 0.006). From the multivariate model, a formula was created to predict SBL. The mean percentage difference between predicted and intraoperative SBL measurements for all patients was 13.7%, and 8.4% for obese patients. LSBM volume is significantly correlated to the SBL. A preoperative SBL prediction with low percentage error could be performed with LSBM volume.

    Full Text Available Abstract Background Familial adenomatous polyposis (FAP is a hereditary disorder characterized by polyposis along the gastrointestinal tract. Information on adenoma status below the duodenum has previously been restricted due to its inaccessibility in vivo. Capsule Endoscopy (CE may provide a useful adjunct in screening for polyposis in the small bowel in FAP patients. This study aims to evaluate the effectiveness of CE in the assessment of patients with FAP, compared to other imaging modalities for the detection of small bowel polyps. Method 20 consecutive patients with previously diagnosed FAP and duodenal polyps, presenting for routine surveillance of polyps at The Royal Melbourne Hospital were recruited. Each fasted patient initially underwent a magnetic resonance image (MRI of the abdomen, and a barium small bowel follow-through study. Capsule Endoscopy was performed four weeks later on the fasted patient. An upper gastrointestinal side-viewing endoscopy was done one (1 to two (2 weeks after this. Endoscopists and investigators were blinded to results of other investigations and patient history. Results Within the stomach, upper gastrointestinal endoscopy found more polyps than other forms of imaging. SBFT and MRI generally performed poorly, identifying fewer polyps than both upper gastrointestinal and capsule endoscopy. CE was the only form of imaging that identified polyps in all segments of the small bowel as well as the only form of imaging able to provide multiple findings outside the stomach/duodenum. Conclusion CE provides important information on possible polyp development distal to the duodenum, which may lead to surgical intervention. The place of CE as an adjunct in surveillance of FAP for a specific subset needs consideration and confirmation in replication studies.

    Purpose: To evaluate the use of computed tomography [CT] in the diagnosis of occult post-traumatic small bowel perforation and to discuss the role of CT in the management of this patient group. Method: This review includes three patients who presented with mild abdominal symptoms following minor blunt abdominal trauma. Initial radiographs and laboratory investigations were unremarkable but their symptoms failed to resolve and contrast-enhanced CT was performed for further evaluation. Results: In each case the CT appearances were indicative of localised small bowel perforation, with no evidence of other visceral injury. In two patients pockets of free intraperitoneal air were present closely related to the second part of the duodenum suggesting injury at this site. In the third case, a thickened proximal jejunal loop was demonstrated with free air and fluid in the adjacent mesentery consistent with a focal perforation. These CT findings were subsequently confirmed at laparotomy. Conclusion: CT is an accurate diagnostic tool in the assessment of clinically and radiologically occult traumatic small bowel injury. The use of CT should be considered in patients who have unresolving abdominal symptoms even after apparently insignificant abdominal trauma.

    We report a rare case of an incarcerated retroperitoneal hernia with or involving the small bowel through the orifice between the right external and internal iliac vessels. A 39-year-old woman was admitted to our hospital because of vomiting and abdominal pain. She had a history of right oophorocystectomy and appendectomy. Abdominal computed tomography revealed small bowel obstruction resulting from an incarcerated retroperitoneal hernia. The small bowel herniated into the retroperitoneal fossa through the orifice between the right external and internal iliac vessels. Laparoscopic reduction of the small bowel was performed, followed by ligation of the sac and placement of a mesh prosthesis through the preperitoneal approach, using a lower midline incision along the previous laparotomy scar. Her postoperative course was uneventful and no recurrence has been observed after surgery.

    Background and purpose: in radiotherapy for prostate cancer, the rectum is considered the dose-limiting organ. The incidence of overlap between the sigmoid colon and/or small bowel and the planning target volume (PTV) as well as the dose to sigmoid colon and small bowel were investigated. Patients and methods: the CT data of 75 prostate cancer patients were analyzed. The clinical target volume (CTV) consisted of prostate and seminal vesicles. The PTV was defined as a three-dimensional expansion of the CTV with a 10-mm margin in craniocaudal and a 7-mm margin in the other directions. All patients were planned to a mean CTV dose of at least 76 Gy. Minimum CTV dose was set at 70 Gy. Dose inhomogeneity within the CTV was kept between 12% and 17%. Sigmoid colon was defined upward from the level where the rectum turned in a transverse plane. Contrast-filled small bowel was contoured on all slices where it was visible. The presence of sigmoid colon and/or small bowel in close vicinity to or overlapping with the PTV was recorded. For each case, the dose to the sigmoid colon and small bowel was calculated. Results: the PTV was found to overlap with the sigmoid colon in 60% and with the small bowel in 19% of the cases. In these patients, mean maximum dose to the sigmoid colon was 76.2 Gy (5th-95th percentile: 70.0-80.7 Gy). Mean maximum dose to the small bowel was 74.9 Gy (5th-95th percentile: 68.0-80.0 Gy). Conclusion: when systematically investigating the anatomic position of sigmoid colon and small bowel in patients accepted for prostate irradiation, parts of both organs were often observed in close vicinity to the PTV. Apart from the rectum, these organs may be dose-limiting in prostate radiotherapy. (orig.)

    Abstract It is often difficult to insert a long intestinal tube (LT) in patients with small bowel obstruction (SBO). We developed a novel technique for inserting an LT without endoscopy called nonendoscopic over-the-wire method via short nasogastric tube (NEWSt). We evaluated the efficacy and safety of NEWSt. We performed a retrospective study of patients who underwent LT insertion for SBO without any indications of strangulation with either NEWSt (n = 16) or endoscopy (n = 17) between November 2011 and February 2015 at our hospital. Univariate analysis was used to assess the success rate of LT placement beyond the duodenojejunal flexure, time required for the procedure, clinical outcomes, and adverse events. The success rate was 100% in both groups. Procedure time was numerically, but not statistically, shorter in the NEWSt group compared with the endoscopy group (24 ± 13 vs 30 ± 13 min; P = 0.174). There were no statistically significant differences between the 2 groups in terms of surgery rate (31% vs 12%; P = 0.225), fasting period (11.3 ± 6.3 vs 9.9 ± 4.5 days; P = 0.482), hospital stay (26.4 ± 22.1 vs 18.7 ± 7.0 days; P = 0.194), and recurrence rate (19% vs 24%; P = 1.0). No serious adverse event was observed in the NEWSt group, whereas serious aspiration pneumonia was observed in 2 patients after LT insertion in the endoscopy group. Without endoscopy, NEWSt enabled the high success rate and the short procedure time for the LT insertion. Prospective, randomized controlled trials are needed. PMID:27893689

    Fructose malabsorption (FM) mimics symptoms of irritable bowel syndrome (IBS), and its prevalence has increased. Diagnosing FM in IBS is challenging because of its overlap with small intestinal bacterial overgrowth (SIBO). We assessed the prevalence of FM by comparing patients with IBS with asymptomatic control individuals after excluding SIBO using the glucose hydrogen breath test (HBT). Patients diagnosed with IBS and asymptomatic control individuals were enrolled prospectively. Dietary habits were assessed with the Food Frequency Questionnaire. After excluding SIBO, participants underwent HBTs with both 15 g and 25 g of fructose. Thirty-five patients with IBS and 35 age- and sex-matched asymptomatic control individuals were enrolled. The 15-g fructose HBT yielded positive results in 7 of the 35 (20.0%) patients with IBS and in 2 of 35 (5.7%) controls ( P = 0.070). The 25-g fructose HBT was positive in 16 of the 35 (45.7%) patients with IBS and in 8 of the 35 (22.9%) controls ( P = 0.040). Analysis of the Food Frequency Questionnaire responses showed no significant differences between the 2 groups in dietary intake, although patients with IBS showed a significantly higher mean fiber intake than controls (21.24 ± 11.35 g vs 15.87 ± 7.07 g, respectively, P = 0.040). The 25-g fructose HBT identified FM in a significantly higher percentage of SIBO-negative patients with IBS than in asymptomatic control individuals, suggesting that FM may correlate with IBS. Education regarding dietary control of foods containing fructose may be useful for the management of patients with IBS.

    Celiac disease (CD) is an immune-mediated enteropathy triggered by exposure to gluten and similar proteins, affecting genetically susceptible persons, increasing their risk of different complications. Small bowels mucosa damage due to CD involves various degrees of endoscopically relevant lesions, which are not easily recognized: their overall sensitivity and positive predictive values are poor even when zoom-endoscopy is used. Confocal Laser Endomicroscopy (CLE) allows skilled and trained experts to qualitative evaluate mucosa alteration such as a decrease in goblet cells density, presence of villous atrophy or crypt hypertrophy. We present a method for automatically classifying CLE images into three different classes: normal regions, villous atrophy and crypt hypertrophy. This classification is performed after a features selection process, in which four features are extracted from each image, through the application of homomorphic filtering and border identification through Canny and Sobel operators. Three different classifiers have been tested on a dataset of 67 different images labeled by experts in three classes (normal, VA and CH): linear approach, Naive-Bayes quadratic approach and a standard quadratic analysis, all validated with a ten-fold cross validation. Linear classification achieves 82.09% accuracy (class accuracies: 90.32% for normal villi, 82.35% for VA and 68.42% for CH, sensitivity: 0.68, specificity 1.00), Naive Bayes analysis returns 83.58% accuracy (90.32% for normal villi, 70.59% for VA and 84.21% for CH, sensitivity: 0.84 specificity: 0.92), while the quadratic analysis achieves a final accuracy of 94.03% (96.77% accuracy for normal villi, 94.12% for VA and 89.47% for CH, sensitivity: 0.89, specificity: 0.98).

    To describe seven cases of gastrointestinal tract (GIT) obstructions and to report a skewed review of the literature. We performed a search of our permanent perinatal database about cases with prenatal ultrasound and MRI diagnosis of gastrointestinal tract obstructions between 2006 and 2013. All cases were followed until hospital discharge and pre-natal diagnosis were confirmed by fetal MRI, postnatal imaging and/or intra-operative findings. Maternal age, parity, gestational age at diagnosis, ultrasound findings, gestational age at delivery, Apgar scores at 1 and 5 min and postnatal outcome have been recorded. We identified seven cases of gastric and small bowel atresia. Karyotype was normal in six cases and abnormal in one co-twin [46,XY dup (20) (qq13.1q13.3)dn] of a dichorionic-diamniotic pregnancy. The mean ± SD for maternal age, gestational age at diagnosis, gestational at delivery, birth weight and Apgar scores at 1 and 5 min were 30.8 ± 4.8 years, 29.8 ± 3.7 weeks, 2507.5 ± 727.5 g and 5.6 ± 2.1, 7.6 ± 1.6, respectively. All fetuses' undergone surgical procedures in the postnatal period and all of them were discharged live from the hospital. Prompted antenatal detection of gastrointestinal tract obstruction using ultrasound proved to be diagnostic in all cases. Fetal MRI aid was a useful complementary diagnostic investigation. Correct pre-natal diagnosis allows adequate counseling, delivery planning and management care by a multidisciplinary team.

    In bowel ischemia, impaired mucosal integrity may allow intestinal pancreatic enzyme products to become systemic and precipitate irreversible shock and death. This can be attenuated by pancreatic enzyme inhibition in the small-bowel lumen. It is unresolved, however, whether ischemically mediated mucosal disruption is the key event allowing pancreatic enzyme products systemic access and whether intestinal digestive enzyme activity in concert with increased mucosal permeability leads to shock in the absence of ischemia. To test this possibility, the small intestinal lumen of nonischemic rats was perfused for 2 h with either digestive enzymes, a mucin disruption strategy (i.e., mucolytics) designed to increase mucosal permeability, or both, and animals were observed for shock. Digestive enzymes perfused included trypsin, chymotrypsin, elastase, amylase, and lipase. Control (n = 6) and experimental animals perfused with pancreatic enzymes only (n = 6) or single enzymes (n = 3 for each of the five enzyme groups) maintained stable hemodynamics. After mucin disruption using a combination of enteral N-acetylcysteine, atropine, and increased flow rates, rats (n = 6) developed mild hypotension (P shock and increase systemic protease activation in the absence of ischemia, implicating bowel mucin disruption as a key event in early ischemia. Digestive enzymes and their products, if allowed to penetrate the gut wall, may trigger multiorgan failure and death.

    Aim: To evaluate the influence of locally active Crohn's disease on systemic small-bowel motility in patients with chronic Crohn's disease compared to healthy individuals. Material and methods: Fifteen healthy individuals (11 men, four women; mean age 37 years) and 20 patients with histopathologically proven active (n = 15; 10 women, 5 men; mean age 45 years) or chronic (n = 5; four women, one man; mean age 48 years) Crohn's disease were included in this institutional review board-approved, retrospective study. Magnetic resonance imaging (MRI; 1.5 T) was performed after standardized preparation. Two-dimensional (2D) cine sequences for motility acquisition were performed in apnoea (27 s). Motility assessment was performed using dedicated software in three randomly chosen areas of the small-bowel outside known Crohn's disease-affected hotspots. The main quantitative characteristics (frequency, amplitude, occlusion rate) were compared using Student's t-test and one-way analysis of variance (ANOVA). Results: Three randomly chosen segments were analysed in each participant. Patients with active Crohn's disease had significantly (p < 0.05) reduced contraction frequencies (active Crohn's disease: 2.86/min; chronic: 4.14/min; healthy: 4.53/min) and luminal occlusion rates (active: 0.43; chronic: 0.70; healthy: 0.73) compared to healthy individuals and patients with chronic Crohn's disease. Contraction amplitudes were significantly reduced during active Crohn's disease (6.71 mm) compared to healthy participants (10.14 mm), but this only reached borderline significance in comparison to chronic Crohn's disease (8.87 mm). Mean bowel lumen diameter was significantly (p = 0.04) higher in patients with active Crohn's disease (16.91 mm) compared to healthy participants (14.79 mm) but not in comparison to patients with chronic Crohn's disease (13.68). Conclusion: The findings of the present study suggest that local inflammatory activity of small-bowel segments in patients with

    Segmental reversal of the small bowel (SRSB) is proposed in patients with short-bowel syndrome (SBS) as a rehabilitative therapy, but its effects on absorption have not been studied. We aimed to determine intestinal macronutrient absorption and home parenteral nutrition (HPN) dependence in SBS patients with intestinal failure. We included in a retrospective study all consecutive patients who had an SRSB between 1985 and 2010 and underwent a study of macronutrient absorption. Patients were matched to SBS controls with the same digestive characteristics. Energy and macronutrient absorption were measured. The dependence on HPN was expressed by the number of infusions per week and by the calories infused daily divided by the basal energy expenditure multiplied by 1.5. Seventeen patients who had an SRSB were matched to 17 control patients. Intestinal absorption was higher in the SRSB group for total calories (69.5% compared with 58.0%), fat (48.4% compared with 33.2%), and protein (62.7% compared with 53.4%) (P < 0.05). Median oral autonomy was 100% ± 38.4% in the SRSB group, whereas it was 79% ± 39.6% in the control group (P < 0.05). The number of calories infused was lower in the SRSB group (500 ± 283 compared with 684 ± 541; P < 0.05), as was HPN dependence (33% ± 20% compared with 48% ± 38%; P < 0.05) at the time of the study. SRSB allows a gain in macronutrient absorption, which is associated with a lower HPN dependence. To our view, SRSB should be integrated in intestinal rehabilitative adult programs.

    Irritable bowel syndrome (IBS) is one of the most prevalent gastrointestinal disorders in developed countries. Its etiology remains unknown; however, a common finding, regardless of IBS subtype, is the presence of altered intestinal barrier. In fact, signaling and location of cell-to-cell adhesion proteins, in connection with increased immune activity, seem abnormal in the intestinal epithelium of IBS patients. Despite that most research is performed on distal segments of the intestine, altered permeability has been reported in both, the small and the large bowel of all IBS subtypes. The small intestine carries out digestion and nutrient absorption and is also the site where the majority of immune responses to luminal antigens takes place. In fact, the upper intestine is more exposed to environmental antigens than the colon and is also a site of symptom generation. Recent studies have revealed small intestinal structural alterations of the epithelial barrier and mucosal immune activation in association with intestinal dysfunction, suggesting the commitment of the intestine as a whole in the pathogenesis of IBS. This review summarizes the most recent findings on mucosal barrier alterations and its relationship to symptoms arising from the small intestine in IBS, including epithelial structural abnormalities, mucosal immune activation, and microbial dysbiosis, further supporting the hypothesis of an organic origin of IBS. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    The aim of this study was to assess the quality of MR imaging and level of adverse effects with increasing concentrations of gastrografin. This is a prospective study with 24 healthy volunteers which were randomised into four groups receiving 50%, 25%, 10% and 0% gastrografin. The endpoint was bowel image quality based on distension, signal homogeneity and wall delineation evaluated by three independent radiologists, and the maximum bowel diameter at three different levels. The subjects also scored any adverse events on a 1-5 scale. The interradiologist agreement was relatively good, with kappa values varying between 0.81 and 0.41. Improved bowel distension and image quality were achieved with increasing concentrations. But significant dose-response effects were found between increasing osmolalities and the bowel diameters and also versus the score of adverse events. The most frequent adverse reactions were diarrhea, nausea and lack of palatability. There is a gradient relationship between increasing osmolality of gastrografin and improved image quality and the score of adverse effects. The optimum concentration of gastrografin is dependent of the tolerance of the adverse events. (orig.)

    Cystic lymphangioma of the small bowel mesentery is a rare clinical entity, especially after childhood. Medical literature reveals a limited number of such cases presenting as acute abdomen due to bowel obstruction, small bowel volvulus and bleeding into the tumour. We present the management experience of an 18-year-old woman who presented with rapid onset diffuse peritonism and raised inflammatory markers. Computed tomography showed a mass in the small bowel mesentery with suspicion of segmental bowel ischaemia. Emergency laparotomy revealed a mass in the mid-jejunal mesentery close to the bowel wall with no bowel ischaemia. The patient made an uncomplicated recovery after segmental bowel resection and end-to-end anastomosis. Histology confirmed the mass as a cystic lymphangioma involving the jejunal mesentery and two small jejunal polyps. Lymphangioma could be considered in the differential diagnosis of an acute abdomen in a young adult when the presentation is atypical.

    With the introduction of stapling devices (SDs), the proportion of hand-sewn (HS) intestinal anastomoses (IAs) has declined. As more IAs are constructed with SDs, there are fewer opportunities for general surgery residents (GSRs) to acquire the skills for HS techniques during their training. Data for this study were extracted from an existing database of all IAs performed at the Department of Surgery of the Morristown Medical Center since 2003. For the purposes of this study, a 5.5-year timeframe was used between July 2006 and 2011, which contained 1659 IA operations on adult patients with resident involvement. GSRs of the 5-year general surgery residency program were grouped by postgraduate year (PGY) for further analysis. The number of all IAs created by each resident during the 5-year training was 67.2 on average. Most of these operations were done in the last 2 years of the training: 45.1% of all IAs in PGY5 and 37.3% of all IAs in PGY4. Of all, 1659 IAs performed in the study period, 711 (42.9% of total) were done laparoscopically and 948 (57.1% of all IAs) were done as open operations. Laparoscopic operations had a proportionally higher rate of SD use when compared to open cases (90.9% vs 82.4%). On average, each resident constructed 9.4 HS IAs (13.98% of all IAs) and 57.8 SD IAs (86.02% of total). Out of all anastomoses, ostomy reversals (30.7%) had the highest percentage of HS suturing followed by right colectomies (27.5%), ileal pouch-anal anastomoses and total colectomies and proctocolectomies (23.3%), small bowel resection (17.0%), and left colectomies (5.5%). Regardless of the location of the operation, stapled and sutured anastomoses had similar outcomes measured by the rate of anastomotic leaks. Residents used significantly more SDs in the creation of anastomoses than HS suturing in the PGY3, PGY4, and PGY5 years. We also documented that attending surgeons who are older more often used HS suturing than their younger colleagues when creating IAs. The

    Full Text Available Purpose: Video capsule endoscopy (VCE is a procedure that uses a wireless camera to take pictures of the gastrointestinal tract. A wireless motility capsule (WMC of a similar size has been developed, which measures pH, pressure, and temperature, and can be used to assess regional and total gastrointestinal transit times. VCE could also potentially be used as a tool for measuring small bowel transit time (SBTT.Methods: This study was designed to obtain SBTT from VCE and compare it with historical data generated by WMC. Gastric transit time (GTT was also measured. Patients were included if the indication for VCE was either iron deficiency anemia (IDA or overt obscure GI bleed (OOGIB and they did not have any known motility disorder. Results from VCE were also compared in diabetic versus non-diabetic patients. Results: There were a total of 147 VCE studies performed, including 42 for OOGIB and 105 for IDA. Median GTT and SBTT were 0.3 and 3.6 hours, respectively. The overall median GTT and SBTT were 0.3 and 3.6 hours, respectively, in the IDA group compared with 0.3 and 3.4 hours in the OOGIB group. When compared with WMC, the GTT and SBTT were significantly faster in both groups (GTT: 3.6 hours and SBTT: 4.6 hours. The median GTT and SBTT were not significantly different in diabetics versus non-diabetics: (GTT: 17.5 vs. 18.0 minutes (P=0.86 and SBTT: 3.9 hours (237 minutes vs. 3.8 hours (230 minutes, respectively (P=0.90.Conclusion: SBTT as measured using VCE is not significantly different in OOGIB compared with IDA. Both GTT and SBTT are significantly faster as assessed by VCE, which is initiated in the fasting state, compared with WMC measurement, which is initiated after a standard meal. In summary, VCE could potentially be used for measuring SBTT in the fasting state.

    We searched the effect of the muscular valve on the management of short bowel syndrome. The motility of the remnant intestine with a special muscular valve after 80% massive distal small bowel resection (MSBR) was evaluated in conscious dogs. The valve (muscular ring) was made by the autointestinal muscle layer holding vascular pedicle. Interdigestive and postprandial bowel motility using bipolar electrodes and/or contractile strain gauge force transducers 2-4 weeks after the surgery, and data of this group (Group I) were compared to the motility in dogs after MSBR without valve construction (Group II) and in controls (Control). Results; Fasting duodenal migrating myoelectric (or motor) complexes (MMCs) in Group I occurred at longer intervals than in Control and almost similarly to those in Group II. MMCs arising from the duodenum were often interrupted before the jejunum above the valve and the anastomosis. The velocity of duodenal MMC propagation was slowed in every intestinal segment including that from the duodenum to the proximal jejunum, and to the jejunum above the anastomosis. Transit time in MSBR group (I and II) from the duodenum to the terminal ileum was extremely shorter than in Control, but there were no differences between in Groups I and II. The duration of the postprandial period without duodenal MMCs in Group I was significantly prolonged than in Control, but was shorter than that in Group II. The muscular valve was frequently activated, and the jejunum covered with the valve was contracted frequently which synchronized with the valve activity. It seemed the valve worked as sphincter. However, intestinal obstruction was not occurred through the jejunum covered by the valve. In conclusion, changes in gut motility after MSBR with the valve construction compensate for the shortened intestine and maintain the bowel content earlier postoperatively in comparison with the MSBR alone, and also contribute to the adaptive increase in the remnant intestinal

    Capsule endoscopy has demonstrated its clinical utility in the evaluation of the small bowel, and, accordingly, it has been suggested that it could be useful for the identification of small-intestinal polyps in patients with polyposis syndromes. The objective was to establish the effectiveness of wireless capsule endoscopy for detecting small-bowel polyps in patients with hereditary GI polyposis syndromes in comparison with barium contrast series. Consecutive patients with GI polyposis syndromes were included. Small-bowel follow-through series and capsule endoscopy were performed within 1 week, in a blind fashion. The number and the location of polyps were analyzed. Twenty-four patients with familial adenomatous polyposis (n = 20) or Peutz-Jeghers syndrome (n = 4) were included. Capsule endoscopy detected small-bowel polyps in 7 of 24 patients (29%), whereas a barium contrast study identified small-intestinal polyps in only 3 of these 7 patients. In the 4 remaining patients, all of them with familial adenomatous polyposis, polyps detected by the capsule but missed in radiographic series were located at either ileum (2 patients), jejunum (1), or duodenum (1). No procedure-related complication was observed in any patient. Wireless capsule endoscopy is a highly accurate technique for the detection of small-bowel polyps in patients with hereditary GI polyposis syndromes, and it represents a valuable alternative to barium contrast series in the surveillance of patients with Peutz-Jeghers syndrome.

    During capsule endoscopy (CE) studies, the complete examination rate (CER) can be increased by prolonging capsule battery life or reducing gastric transit time (GTT) and/or small bowel transit time (SBTT). However, despite enhanced battery life, 10% of studies remain incomplete. Previously studied interventions to reduce SBTT and enhance CER have produced conflicting results. We hypothesize that this may be a consequence of an insufficiently potent stimulus of small bowel motility. To examine whether potent stimulation of the cephalic response of digestion during small bowel CE reduces GTT and/or SBTT and thus increases the CER. A single-blind randomized trial was performed to evaluate the effect of bacon sham feeding on GTT, SBTT and CER. Baseline characteristics were similar between 63 sham fed patients and 59 controls. The median GTT was 17 min (9-65) in the bacon group and 25 min (14-55) in the control group. The median SBTT was 199 min (119-316) and 222 min (151-287), respectively. Cox proportional hazards model demonstrated no significant difference between groups for GTT (rate ratio 1.03, 95% CI 0.71-1.51, P = 0.87) or SBTT (rate ratio 1.02, 95% CI 0.70-1.49, P = 0.93). Although the taste of bacon was considered favorably by 72% of participants, taste did not correlate with GTT (ρ = 0.03, P = 0.83) or SBTT (ρ = - 0.115, P = 0.33). The CER was 91 and 95% in the bacon and control groups, respectively (P = 0.35). Bacon sham feeding has no effect on GTT, SBTT or CER and cannot be recommended in clinical practice.

    Fluid accumulation in either the obstructed upper or lower intestinal segments of the dog was found in most animals to be negligible. Distention pressures of 25 cm of water tended to reduce fluid accumulation within the intestinal lumen. These studies suggest that if the dog is comparable to man, the intraluminal accumulation of fluid in the obstructed small bowel of man might be due to alterations in blood supply to the intestine, rather than to obstruction per se, or the accumulated fluid originates proximal to the jejunum.

    Full Text Available Background. We aimed to evaluate the efficacy of various diagnostic tools such as computerized tomography (CT, small bowel follow-through (SBFT, and capsule endoscopy (CE in diagnosing small bowel tumors (SBTs. Additionally, we aimed to evaluate the clinical features of SBTs missed by CE. Methods. We retrospectively studied 79 patients with histologically proven SBT. Clinical data were analyzed with particular attention to the efficacy of CT, SBFT, and CE in detecting SBT preoperatively. We also analyzed the clinical features of SBTs missed by CE. Results. The most common symptoms of SBT were bleeding (43% and abdominal pain (13.9%. Diagnostic yields were as follows: CT detected 55.8% of proven SBTs; SBFT, 46.1%; and CE, 83.3%. The sensitivity for detecting SBTs was 40.4% for CT, 43.9% for SBFT, and 79.6% for CE. Two patients with nondiagnostic but suspicious findings on CE and seven patients with negative findings on CE were eventually found to have SBT. These nine patients were eventually diagnosed with gastrointestinal stromal tumor (4, small polyps (3, inflammatory fibroid polyp (1, and adenocarcinoma (1. These tumors were located in the proximal jejunum (5, middle jejunum (1, distal jejunum (1, and proximal ileum (1. Conclusion. CE is more efficacious than CT or SBFT for detecting SBTs. However, significant tumors may go undetected with CE, particularly when located in the proximal jejunum.

    1979-01-01

    Circulating blocking factors capable of abrogating cell-mediated immune responses measured by in vitro lymphoid-cell cytotoxicity were identified in the sera of Holtzman outbred rats 6 to 9 months after a single exposure of only the temporarily exteriorized, hypoxic ileum and jejunum to 1700 to 2000 R of X radiation. Such factors were found to exist in the serum of every animal exposed to the ionizing radiation regardless of whether a visibly identifiable small-bowel adenocarcinoma existed or subsequently would develop. Protection of cultured x-ray-induced rat small-bowel cancer cells from destruction by tumor-sensitized lymphoid cells as measured by the release of lactoperoxidase-catalyzed radioiodinated membrane proteins from the tumor target cells was conferred by the action of the blocking factors at both effector and target cell levels. The results of this study demonstrate that exposure of only the rat small intestine to ionizing radiation leads to elaboration of circulating factors identifiable several months postirradiation which will block cell-mediated immune responses directed against cancer cells developing in the exposed tissue

    Small-bowel MRI based on contrast-enhanced T1-weighted sequences has been challenged by diffusion-weighted imaging (DWI) for detection of inflammatory bowel lesions and complications in patients with Crohn disease. To evaluate free-breathing DWI, as compared to contrast-enhanced MRI, in children, adolescents and young adults with Crohn disease. This retrospective study included 33 children and young adults with Crohn disease ages 17 ± 3 years (mean ± standard deviation) and 27 matched controls who underwent small-bowel MRI with contrast-enhanced T1-weighted sequences and DWI at 1.5 T. The detectability of Crohn manifestations was determined. Concurrent colonoscopy as reference was available in two-thirds of the children with Crohn disease. DWI and contrast-enhanced MRI correctly identified 32 and 31 patients, respectively. All 22 small-bowel lesions and all Crohn complications were detected. False-positive findings (two on DWI, one on contrast-enhanced MRI), compared to colonoscopy, were a result of large-bowel lumen collapse. Inflammatory wall thickening was comparable on DWI and contrast-enhanced MRI. DWI was superior to contrast-enhanced MRI for detection of lesions in 27% of the assessed bowel segments and equal to contrast-enhanced MRI in 71% of segments. DWI facilitates fast, accurate and comprehensive workup in Crohn disease without the need for intravenous administration of contrast medium. Contrast-enhanced MRI is superior in terms of spatial resolution and multiplanar acquisition. (orig.)

    Purpose: To find correlation between dose-volume histograms (DVHs) of the intestinal cavity (IC) and moderate-severe acute bowel toxicity in men with prostate cancer treated with pelvic nodal irradiation. Methods and Materials: The study group consisted of 191 patients with localized prostate cancer who underwent whole-pelvis radiotherapy with radical or adjuvant/salvage intent during January 2004 to November 2007. Complete planning/clinical data were available in 175 of these men, 91 of whom were treated with a conventional four-field technique (50.4 Gy, 1.8 Gy/fraction) and 84 of whom were treated with IMRT using conventional Linac (n = 26, 50.4 Gy, 1.8 Gy/fraction) or Helical TomoTherapy (n = 58, 50-54 Gy, 1.8-2 Gy/fraction). The IC outside the planning target volume (PTV) was contoured and the DVH for the first 6 weeks of treatment was recovered in all patients. The correlation between a number of clinical and DVH (V10-V55) variables and toxicity was investigated in univariate and multivariate analyses. The correlation between DVHs for the IC outside the PTV and DVHs for the whole IC was also assessed. Results: Twenty-two patients experienced toxicity (3/22 in the IMRT/tomotherapy group). Univariate analyses showed a significant correlation between V20-V50 and toxicity (p = 0.0002-0.001), with a higher predictive value observed for V40-V50. Previous prostatectomy (p = 0.066) and abdominal/pelvic surgery (p = 0.12) also correlated with toxicity. Multivariate analysis that included V45, abdominal/pelvic surgery, and prostatectomy showed that the most predictive parameters were V45 (p = 0.002) and abdominal/pelvic surgery (p = 0.05, HR = 2.4) Conclusions: Our avoidance IMRT approach drastically reduces the incidence of acute bowel toxicity. V40-V50 of IC and, secondarily, previous abdominal/pelvic surgery were the main predictors of acute bowel toxicity.

    to know the effect of nicotine on angiogenesis and myofibroblast formation in anastomoses of the small bowel of rats. we randomly divided 60 Wistar rats into the groups Nicotine (N) and control (C), according to the proposed treatment. Each group was subdivided into three subgroups according to the time interval used for the evaluation (7, 14 or 28 days). The N group with 30 animals received nicotine subcutaneously at a dose of 2mg/kg body weight, diluted in 0.3ml of 0.9% saline, twice daily for 28 days prior to the operation, and for more 7, 14 or 28 days, depending on the subgroup. The C group (also 30 animals) received only saline on the same conditions and time intervals. After 28 days we carried out an end-to-end anastomosis 10cm distal to the duodenojejunal flexure in each rat. After 7, 14 or 28 days after surgery, we euthanized ten animals of each group, sent specimens of the anastomosis areas, 1cm proximal to 1cm distal, to counting of blood vessels and myofibroblasts through immunohistochemical staining by the application of monoclonal anti-factor VIII antibodies and anti-smooth muscle alpha-actin. the administration of nicotine led to the decrease in the number of blood vessels measured on the 28th postoperative day and the number of myofibroblasts measured on the seventh day following completion of the anastomoses. administration of nicotine was deleterious on angiogenesis and myofibroblast formation in rats' small intestine anastomoses. conhecer o efeito da nicotina sobre a angiogênese e formação de miofibroblastos em anastomoses do intestino delgado de ratos. sessenta ratos Wistar foram divididos de maneira aleatória em grupos Nicotina(N) e Controle (C), conforme o tratamento proposto.

    Weiss, R.G.; Stryker, J.A.

    1982-01-01

    Thirty patients who were undergoing pelvic radiotherapy had 14 C-lactose breath tests performed in the first and fifth weeks of treatment. In Group I (21 patients), a significant portion of the small intestine was irradiated, and in Group II (9 patients), only a small portion of the small intestine was irradiated. In Group I, the average reductions in the excretion of ingested 14 C between the first- and fifth-week tests were 41.5% at 1/2 hour postingestion (p 0.05). The data suggest that lactose malabsorption is a factor in the etiology of the nausea, vomiting, and diarrhea experienced by patients who are undergoing pelvic radiotherapy, and that the amount of bowel included in the treatment volume significantly influences the degree of malabsorption

    AIM: The aim of this study was to determine if oral administration of a non-absorbable anechoic solution conveys any benefit during abdominal ultrasound (US), with special reference to its accuracy. MATERIALS AND METHODS: Fifty-three adult out-patients scheduled for small bowel barium enema (SBE) were included. The day before SBE all patients underwent abdominal US before and after oral administration of an isotonic non-absorbable electrolyte solution containing polyethylene glycol (PEG-ELS). Sensitivity and specificity were evaluated using SBE as a gold standard. RESULTS: After ingestion of PEG-ELS satisfactory distension of the intestinal lumen was obtained (11-25 mm) with sequential visualization of jejunoileal loops in 30.9 {+-} 17.3 min. In 15 out of 53 cases both US and SBE showed bowel changes characteristic of Crohn's disease. In three out of 53 cases both US and SBE showed neoplasms. In one out of 53 cases US was negative, SBE positive for local nodularity and ulcerations typical of Crohn's disease. In one out of 53 cases US was negative, SBE positive for macronodularity consistent with coeliac disease. In five out of 53 cases US was negative, while SBE was positive for mininodularity expressive of lymphoid hyperplasia. In 28 out of 53 cases both examinations were negative. CONCLUSION: PEG-ELS administration allows a thorough US investigation of the small bowel, with fair sensitivity (72%) and excellent specificity (100%). False negative findings are mainly due to lymphoid hyperplasia, a feature of uncertain significance in adults. Cittadini G. et al.(2001)

It can be fatal if not recognized early. Only one previous report has been found in the English literature. Case presentation A 36-year old Caucasian, normally fit woman presented with abdominal distension and vomiting five days post-normal vaginal delivery at term. Localised peritonitis in the right iliac fossa developed in the next few days, and caecal perforation was found at laparotomy, without evidence of appendicitis or colitis. Conclusion Although very rare, Ogilvie's syndrome should be considered by obstetricians, general surgeons and general practitioners as a potential cause of vomiting and abdominal pain following normal vaginal delivery. Early recognition and management are essential to minimize the possibility of developing serious complications.

    To evaluate the change of the wall of obstructed small bowel loop on ultrasonography (US), the changes of pre- and post-obstructed segments were examined by using US and correlated with histopathologic findings. Small bowel loops of seven rabbits were caused to be obstructed by surgery. One of them was sacrificed after 12 hours, and six were after 24 hours. The bowel loop of about 10 cm in length was cut and removed from obstructed site for evaluation with US and correlation with histopathologic findings. One control was also included and correlated by the same way, without bowel obstruction. After US examination, the bowel loops were opened at the mesenteric border. They were mounted into hard paper, and put in a plastic pail filled with 2 liters of physiologic saline. The specimens were imaged with 10 MHz linear array transducer with high definition zoom. After sonographic examination, the specimens were fixed with 10% formalin solution and stained by hematoxylin-eosin. The segments of small bowel showed three layers on US, which were hyperechoic, hypoechoic, and hyperechoic from the mucosal surface. The total thickness of the pre-obstructed segments was 1.65 {+-} 0.15 mm, and of post-obstructed was 1.62 {+-} 0.14 mm; there was no significant difference (p>0.05). The ratio of the second hypoechoic layer to total thickness was 23% at pre-obstructed segments, 17% at post-obstructed, and 7% at the control. Under microscopic examination, the total thickness of the pre-obstructed segments were measured as 0.95 {+-} 0.12 mm, and that of the post-obstructed was measured as 0.9{+-} 0.11 mm; there was no significant difference (p>0.05). The total thickness on US was about 0.7 mm thicker than in microscopic findings, so considering the ratio of each layers, the first hyperechoic and the second hypoechoic layers were assumed to be mucosal layer, and the third hyperechoic layer was assumed to be submucosal and muscle layers. Histopathologic findings of both pre- and post

    This treatment planning study analyzes dose coverage and dose to organs at risk (OAR) in intensity-modulated radiotherapy (IMRT) of rectal cancer and compares prone vs. supine positioning as well as the effect of dose optimization for the small bowel (SB) by additional dose constraints in the inverse planning process. Based on the CT datasets of ten male patients in both prone and supine position, a total of four different IMRT plans were created for each patient. OAR were defined as the SB, bladder, and femoral heads. In half of the plans, two additional SB cost functions were used in the inverse planning process. There was a statistically significant dose reduction for the SB in prone position of up to 41% in the high and intermediate dose region, compared with the supine position. Furthermore, the femoral heads showed a significant dose reduction in prone position in the low dose region. Regarding the additional active SB constraints, the dose in the high dose region of the SB was significantly reduced by up to 14% with the additional cost functions. There were no significant differences in the dose distribution of the planning target volume (PTV) and the bladder. Prone positioning can significantly reduce dose to the SB in IMRT for rectal cancer and therefore should not only be used in 3D conformal radiotherapy but also in IMRT of rectal cancer. Further protection of the SB can be achieved by additional dose constraints in inverse planning without jeopardizing the homogeneity of the PTV. (orig.)

    The aim of this prospective study was to evaluate the feasibility, tolerance and performance of virtual enteroscopy (VE) using carbon dioxide for small-bowel distension in patients with suspected small-bowel tumours (SBTs). After IRB approval, 17 patients with suspected SBTs were prospectively included. Radiation dose was compared to 34 matched patients (2 for 1) for age, gender and body weight, who had undergone CT-enteroclysis with neutral contrast (CTE). Performance of VE was evaluated through comparison with the current standard of reference, including surgery and/or enteroscopy and/or follow-up. Tolerance was excellent in 16/17 patients (94%). The radiation dose was lower for VE than for CTE (533 ± 282 vs. 974 ± 505 mGy.cm; p = 0.002). With VE, a total of 25 polyps >5 mm in size were depicted in 12/17 patients. On a per-lesion analysis, sensitivity and positive predictive value of VE were 92.0% and 92.0%, respectively. On a per-segment analysis VE had a sensitivity and specificity of 95.0% and 87.0%, respectively. Our preliminary study suggests that VE is a feasible and well-tolerated technique with high sensitivity and specificity for the diagnosis of SBT. (orig.)

    The study purpose was to investigate the ability of Emergency Department CT scan to predict the need for operative intervention in patients hospitalized for small bowel obstruction (SBO) likely secondary to adhesions (ASBO) and initially managed nonoperatively. Retrospective case series. Statistical analysis was done with independent-samples t-test and chi-square to identify correlation between variables and outcome of nonoperative management. Tertiary care academic medical center. Of 200 consecutive patients hospitalized for SBO, 108 were included in the study with a diagnosis of ASBO and received initial nonoperative management. Exclusion criteria were need for emergency surgery (e.g. peritonitis) or other diagnoses (e.g. neoplasms, hernias, Crohn's disease). CT findings such as transition point, small bowel faeces, high grade obstruction, and abnormal vascular course were correlated with failure of nonoperative management. Only 18 patients (16.7%) required operative intervention, while the other 90 (83.3%) were successfully discharged after nonoperative care. There was no correlation between CT scan findings and treatment outcome. Emergency Department CT scan findings do not significantly alter management decisions in patients admitted for ASBO and managed initially with nonoperative care.

    Small bowel neuroendocrine tumors (SBNETs) have been increasing in frequency over the past decades, and are now the most common type of small bowel tumor. Consequently, general surgeons and surgical oncologists are seeing more patients with SBNETs in their practices than ever before. The management of these patients is often complex, owing to their secretion of hormones, frequent presentation with advanced disease, and difficulties with making the diagnosis of SBNETs. Despite these issues, even patients with advanced disease can have long-term survival. There are a number of scenarios which commonly arise in SBNET patients where it is difficult to determine the optimal management from the published data. To address these challenges for clinicians, a consensus conference was held assembling experts in the field to review and discuss the available literature and patterns of practice pertaining to specific management issues. This paper summarizes the important elements from these studies and the recommendations of the group for these questions regarding the management of SBNET patients.

    2017-01-01

    Purpose I introduce the use of transanal intestinal long tube (TILT) using nasogastric tube. TILT passes from anus to the anastomosis, helping to decompress a dilated bowel loop. Methods TILT procedure was limited to those patients predicting a severe luminal size discrepancy after intestinal anastomosis, and who had postoperative prolonged ileus. We retrospectively reviewed the medical records of 10 infants (7 male an 3 female patients) who were treated using the TILT procedure between 2012 and 2016. Results Median gestational age was 27+5 weeks and birth weight was 940 g. The first operation was done at a median of 4.5 days after birth due to necrotizing enterocolitis perforation (4 cases), isolated intestinal perforation (3 cases), meconium related ileus (1 case), congenital ileal volvulus (1 case), and ileal atresia (1 case). Nine cases of ileostomy closure were planned at a median of 130.5 days with a body weight of 3,060 g. For the ileal atresia case, TILT procedure without additional small bowel resection was performed to treat postoperative prolonged ileus. Nine out of ten were well functioned and defecation via anus was observed in a median of 4.5 days. Milk feeding began at a median of 6 days and the long intestinal tube was removed in a median of 14.5 days. Conclusion I suggested that TILT procedure could be a noninvasive operative option, predicting of size mismatched anastomosis causing prolonged ileus. Passive drainage of proximal intestinal contents might be helpful for decompress endoluminal pressure during the time of anastomosis healing with bowel movement recovery. PMID:28932729

    Standardized strategy of bowel preparation before video capsule endoscopy (VCE) remains controversial. This study aimed to assess the ideal dose of PEG, based on small bowel visualization quality (SBVQ), diagnostic yield (DY), and complete rate (CR) of VCE using a network meta-analysis (NMA) of randomized controlled trials (RCTs). This NMA included RCTs comparing any of the following bowel preparation interventions for VCE: fasting overnight ("Fast"), 1 liter PEG ("PEG 1L"), 2-liter PEG ("PEG 2L"), or 4-liter PEG ("PEG 4L"). The authors searched papers in PubMed, Cochrane Library, and Embase as of June 2016. The cumulative ranking (SUCRA) probabilities to rank different doses of PEG and Fast were used. The search engine provided 102 studies. Nine RCTs including 982 patients were incorporated into this analysis. All studies showed low risk of bias of blinding. SUCRA provided an initial ranking among these strategies, in which PEG 2 L showed the best score in SBVQ (PEG 2 L, 89.4%; PEG 1 L, 62.5%; PEG 4 L, 44.0%; Fast, 4.1%) and DY (PEG 2 L, 74.6%; PEG 1 L 28.1%; PEG 4 L 65.9%; Fast 31.4%) of VCE. No significant difference was shown in the analysis of CR. This study recommends PEG 2 L as the ideal dose, which may improve the SBVQ of VCE and, therefore, diagnostic accuracy. Multi-center randomized controlled trials are required to verify these findings.

    To determine if general anesthesia with sevoflurane and laparoscopic surgery changed gastric and small bowel propulsive motility or pH in dogs. Prospective, controlled trial. Twelve, 19-24 months old, female, Treeing Walker Hound dogs, weighing 23-30 kg. Dogs were anesthetized for a median of 8.5 hours during another study to determine the minimum alveolar concentration of sevoflurane using a visceral stimulus. Gastric and small bowel motility were determined using a sensor capsule that measures pressure, pH and temperature. Gastric transit time and motility index were calculated. For 8/12 dogs, gastric motility, pH and transit time were measured. In 4/12 dogs, small bowel motility and pH were measured. Anesthesia decreased gastric and small bowel motility but did not change luminal pH. Mean gastric contraction force decreased from median (range) 11 (8-20) to 3 (1-10) mmHg (p gastric motility index decreased from 0.63 (0-1.58) to 0 (0-0.31; p = 0.01). Frequency of contractions did not change, 3.7 (1.6-4.4) versus 2.8 (0.1-5.1) contractions minute(-1) (p = 0.1). Gastric motility returned to normal 12-15 hours following anesthesia. Gastric emptying was prolonged from 12 (5.3-16) to 49 (9.75-56.25) hours (p gastric or small bowel parameters beyond those produced by general anesthesia. The force of gastric and small bowel contractions decreased during sevoflurane anesthesia for laparoscopy. Although gastric motility returned to normal within 12-15 hours the impairment of gastric emptying lasted 30-40 hours, predisposing dogs to postoperative ileus. © 2013 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    This article gives an overview of the possibilities of conventional radiography in the diagnosis of inflammatory bowel disease of the small intestine and colon.Material and methods For more than 25 years we examine the small bowel employing enteroclysis with barium and methylcellulose and the colon with the usual double-contrast method. In the last 152 months 1560 small bowel enemas were performed. In the last 40 months 410 examinations of the colon were performed. There is a thirty percent decrease in enteroclysis examinations within the past 5 years,however, the rate of examinations with positive results increased from 46 to 57%.The proportion of the inflammatory small intestinal diseases (not only Crohn's disease) remained constant with 18%.Concerning the examinations of the colon for inflammatory disease we confirmed the diagnosis in seven cases.The radiation exposure for the enteroclysis in inflammatory diseases was 7mSv, for colon examinations 14 mSv. Barium examinations, especially of the stomach and colon are decreasing in frequency.Therefore the art of performance and interpretation might get lost.Enteroclysis, however, is still the method of reference for the other imaging methods.The advantages compared to the other imaging methods are the excellent presentation of the details of the mucosal surface and the observation of functional disorders.

    To compare dual-energy computed tomography (CT) with conventional CT for the detection of small-bowel ischemia in an experimental animal model. The study was approved by the animal care and use committee and was performed in accordance with the Guide for Care and Use of Laboratory Animals issued by the National Research Council. Ischemic bowel segments (n = 8) were created in swine (n = 4) by means of surgical occlusion of distal mesenteric arteries and veins. Contrast material-enhanced dual-energy CT and conventional single-energy CT (120 kVp) sequences were performed during the portal venous phase with a single-source fast-switching dual-energy CT scanner. Attenuation values and contrast-to-noise ratios of ischemic and perfused segments on iodine material-density, monospectral dual-energy CT (51 keV, 65 keV, and 70 keV), and conventional 120-kVp CT images were compared. Linear mixed-effects models were used for comparisons. The attenuation difference between ischemic and perfused segments was significantly greater on dual-energy 51-keV CT images than on conventional 120-kVp CT images (mean difference, 91.7 HU vs 47.6 HU; P conventional CT by increasing attenuation differences between ischemic and perfused segments on low-kiloelectron volt and iodine material density images. © RSNA, 2014.

    Malignant tumors of the small bowel are uncommon and include multiple histologic strains, which helps explain the existing limited understanding of them. The aim of this study was to evaluate surgically treated small bowel tumors and to determine the clinical and pathological characteristics that can have an impact on patient outcome. A retrospective, observational, and descriptive study was carried out. The case records of patients with small bowel tumor that were surgically treated at the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" from 1990 to August 2011 were analyzed using the SPSS version 17.0 statistical package. Thirty-eight small bowel tumor patients were found that had been operated on within the time frame studied. Fifteen of them were women (39.50%) and 23 were men (60.50%), and the mean age was 55.6 years. The histologic distribution was 13 adenocarcinomas (34.20%), 10 neuroendocrine tumors (26.30%), 8 sarcomas (21.10%) and 4 lymphomas (10.50%). There was an increase in the incidence of sarcomas and adenocarcinomas, whereas lymphomas and neuroendocrine tumors were evenly distributed. An increase in small bowel tumor incidence in the last few years was observed and adenocarcinoma was the most frequent tumor in the study population. It is important to have a high degree of suspicion for this disease when patients present with symptoms such as gastrointestinal bleeding, bowel obstruction, anemia, and weight loss, because early diagnosis is essential for guaranteeing favorable outcome.

    are subtype B cell. Case Report: It´s presented a case of rare small bowel lymphoma in a female patient of 77 years who sought medical care with nonspecific symptoms and an anemic framework. Radiological examinations were essential for diagnosis for diagnostic enlightenment and propaedeutics. Tumor markers were negative and the inflamatorious tests activities were positives. In hospitalization, the patient had an abrupt worsening in her clinic picture, needing a surgery. During the operation was identified in the proximal jejunum a perfurative damage with an ulcerated aspect with ulcers, adhesions in the bladder and in fundus of the uterus. The patient did not evaluated well and died after three days. The pathology confirmed a diffuse No Hodgkin lymphoma of Large B-cells with a high rate of cell proliferation. Discussion: The preoperative radiological diagnosis of tumor of the small intestine is only obtained in a small percentage of symptomatic patients. Imaging studies show infiltrative, polypoid, or aneurysmatic morphologicals types .Usually occurs circumferential involvement of the handle, with irregular thickening of the folds of variable length. Conclusion: The intent of this study is to document a rare tumor of the small bowel Non-Hodgkin Lymphoma Diffuse Large B-Cell type, multicentric, that was difficult to diagnose and with a rapid evolution of symptoms, which resulted in acute intestinal obstruction, requiring emergency surgery.

    The ketohexose D-tagatose is a new sweetener with a low energy content. This low energy content may be due to either low absorption of the D-tagatose or decreased absorption of other nutrients. The aims of this study were to measure the excretion of D-tagatose from the human small bowel, to calculate the apparent absorption of D-tagatose, and to study the effects of D-tagatose on the small-bowel excretion of other carbohydrates. A controlled diet was served for 2 periods of 2 d during 3 consecutive weeks to 6 ileostomy subjects. In one of the periods, 15 g D-tagatose was added to the diet daily. Duplicate portions of the diet and ileostomy effluents were freeze-dried and analyzed to calculate the apparent net absorption of D-tagatose and carbohydrates. Median D-tagatose excretion was 19% (range: 12-31%), which corresponded to a calculated apparent absorption of 81% (69-88%). Of the total amount of D-tagatose excreted [2.8 g (1.7-4.4 g)], 60% (8-88%) was excreted within 3 h. Between 3 and 5 h, 32% (11-82%) was excreted. Excretion of wet matter increased by 41% (24-52%) with D-tagatose ingestion. Sucrose and D-glucose excretion increased to a small extent, whereas no significant changes were found in the excretion of dry matter, energy, starch, or D-fructose. The apparent absorption of 15 g D-tagatose/d was 81%. D-Tagatose had only a minor influence on the apparent absorption of other nutrients.

    Purpose: To evaluate the biodistribution of sodium pertechnetate (Na 99m TcO 4 ) in organs and tissues, the morphometry of remnant intestinal mucosa and ponderal evolution in rats subjected to massive resection of the small intestine. Methods:Twenty-one Wistar rats were randomly divided into three groups of 7 animals each. The short bowel (SB) group was subjected to massive resection of the small intestine; the control group (C) rats were not operated on, and soft intestinal handling was performed in sham rats. The animals were weighed weekly. On the 30th postoperative day, 0.1 mL of Na 99m TcO 4 , with mean activity of 0.66 MBq was injected intravenously into the orbital plexus. After 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. The biopsies were washed with 0.9% NaCl.,The radioactivity was counted using Gamma Counter Wizard TM 1470, Perkin-Elmer. The percentage of radioactivity per gram of tissue (%ATI/g) was calculated. Biopsies of the remaining jejunum were analysed by HE staining to obtain mucosal thickness. Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p 99m TcO 4 in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week. The jejunal mucosal thickness of the SB rats was significantly greater than that of C and sham rats (p 99m TcO 4 was not affected by massive intestinal resection, suggesting that short bowel syndrome is not the cause of misleading interpretation, if an examination using this radiopharmaceutical is indicated.

    Background and Aims: Azathioprine [AZA] is recommended for maintenance of steroid-free remission in inflammatory bowel disease IBD. The aim of this study has been to establish the incidence and severity of AZA-induced pancreatitis, an idiosyncratic and major side effect, and to identify specific risk factors. Methods: We studied 510 IBD patients [338 Crohn’s disease, 157 ulcerative colitis, 15 indeterminate colitis] with initiation of AZA treatment in a prospective multicentre registry study. Acute pancreatitis was diagnosed in accordance with international guidelines. Results: AZA was continued by 324 [63.5%] and stopped by 186 [36.5%] patients. The most common cause of discontinuation was nausea [12.2%]. AZA-induced pancreatitis occurred in 37 patients [7.3%]. Of these: 43% were hospitalised with a median inpatient time period of 5 days; 10% had peripancreatic fluid collections; 24% had vomiting; and 14% had fever. No patient had to undergo nonsurgical or surgical interventions. Smoking was the strongest risk factor for AZA-induced acute pancreatitis [p pancreatitis is a common adverse event in IBD patients, but in this study had a mild course in all patients.

    Irritable bowel syndrome (IBS) patients suffer from visceral hypersensitivity and show increased activity in the brain emotional arousal network following a rectal stimulus, compared with controls. Serotonergic activity can be decreased by acute tryptophan depletion (ATD), which increases visceral perception and also increases activity in the brain's emotional arousal network during rectal stimulation. Treatment with a serotonin reuptake inhibitor such as citalopram is effective in some IBS patients. Hence, serotonergic modulation alters visceral perception. However, it is not clear whether serotonergic modulation alters rectal motor function. The aims of the study were to evaluate the effect of the administration of ATD and citalopram on rectal motor function in diarrhea-predominant IBS (d-IBS) patients and controls using a barostat procedure. Following a randomized, double-blind placebo-controlled crossover design, an ATD and citalopram experiment was conducted. Fourteen d-IBS patients and 14 healthy, matched (age, sex, BMI) controls participated. Rectal volume (RV), adaptive relaxation (RAR), and compliance (RC) were determined using a barostat procedure. d-IBS patients showed significantly decreased RV (P0.1). d-IBS patients have disturbed rectal pressure-volume relations. Visceral perception in IBS is associated with both increased activity in the brain's emotional arousal network and decreased RC. Acutely decreasing or increasing serotonergic activity does not affect these characteristics in d-IBS patients or healthy controls. The pathophysiology in d-IBS contains both a rectal motor component and a central neuropsychologic component.

    Capsule endoscopy (CE) has the highest sensitivity in the evaluation of small-bowel mucosa in Crohn's disease (CD). Recent guidelines recommend the use of validated CE scores to assess small-bowel inflammatory activity in CD. Lewis score (LS) and Capsule Endoscopy Crohn's Disease Activity Index (CECDAI) are the currently available validated scores, but comparative studies are scarce. Moreover, correlation of these endoscopic scores with biomarkers and clinical activity is lacking. This study aims to compare LS with CECDAI, to determine cutoff values for CECDAI similar to those of LS (135-790), and to correlate LS and CECDAI with biomarkers and symptoms. All patients with CD who underwent CE between March/2010 and February/2016 were included. LS and CECDAI were determined after analysis of each CE. In patients with small-bowel CD, C-reactive protein (CRP) and Harvey-Bradshaw index (HBI) were evaluated. descriptive statistics, Spearman's correlation coefficient and linear regression analysis. p<0.05. Fifty-three patients were included and the mean values obtained for LS were 1147±1453, CECDAI 11.3±6.9, CRP 0.92±1.5mg/dL and HBI 2.4±2.8. There was a very strong correlation between LS and CECDAI (r s =0.878; p<0.0001) and thresholds values of 135-790 in LS corresponded to 7.7-10.3 cutoff values in CECDAI, respectively. Neither CRP correlated with LS (r s =0.068; p=0.72) or CECDAI (r s =-0.004; p=0.98), nor HBI with LS (r s =-0.15; p=0.40) or CECDAI (r s =-0.10; p=0.23). Correlation between the two CE activity scores was very strong, with LS thresholds of 135-790 corresponding to CECDAI values of 7.7-10.3. HBI and CRP had no correlation with CECDAI and LS.

    67 patients were operated for intestinal complications following radiotherapy. The lesions were located in the small bowel (n = 41) and in the sigmoid colon/rectum (n = 33). 98.5% of the patients were females, the most frequent cause for irradiation being ovarian cancer. Bowel stenosis with resultant chronic or acute ileus was the most frequent indication for operation. Percutaneous irradiation resulted in a significantly higher proportion of small bowel lesions (77%, p = 0.001), whilst endocavitary irradiation was followed in 67% of cases by colorectal lesions. Different application modality of irradiation also resulted in completely different symptoms for small and large bowel lesions. The operative mortality was 9.5%. Peritonitis following anastomotic leakage was the cause of death in 6 of 7 cases. In the treatment of small bowel ileus mortality following bowel resection (9%, one of 11 cases) was comparable to that of the bypass operation (6%, one of 18 cases). Both operation methods seem to be justified. Single-layer anastomosis resulted in zero mortality (21 cases) for ileus operation compared with 19% mortality (16 cases) in double-layer anastomosis and should be prefered for operations on the irradiated bowel.

    Although there is evidence about the beneficial effects of probiotics, their effects on aspirin-induced small bowel injuries have not been well examined. We evaluated the effects of the probiotic Lactobacillus gasseri OLL2716 (LG) on aspirin-induced small intestinal lesions, such as ulcers, erosions, reddened lesions, and bleeding. This study enrolled 64 patients who received aspirin for more than 1 month and provided written informed consent to be part of the study. The patients received 112 ml of yogurt containing LG or placebo twice daily for 6 weeks. Small bowel injuries were evaluated by capsule endoscopy before and after consuming the yogurt. The effect of LG on patient symptoms was also assessed using the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG) and Gastrointestinal Symptom Rating Scale (GSRS) questionnaires before and after 6 weeks of treatment. There was no significant difference in any baseline characteristics and the number of small bowel mucosal breaks between the 2 groups. In contrast with the placebo group, the LG group had significantly fewer small bowel mucosal breaks and reddened lesions after 6 weeks (p gastrointestinal symptoms. © 2016 S. Karger AG, Basel.

    Full Text Available Abdominal pain and distention in children are commonly encountered problems in the pediatric emergency room. The majority of complaints are found to be due to benign entities such as gastroenteritis and constipation. What confounds these diagnoses is that young children often deliver a challenging and unreliable exam. Thus, it often becomes exceedingly problematic to differentiate these benign conditions from surgical conditions requiring prompt attention including small or large bowel obstruction, volvulus, and appendicitis. The cases highlight Sapovirus as a cause of severe abdominal distention and vomiting in children and this report is the first to describe and demonstrate the impressive radiologic findings that may be associated with this infection. Surgeons should heed this information and hesitate to emergently operate on similar children.

    This work evaluates carbon dioxide as a contrast medium for magnetic resonance imaging of the stomach and small bowel. Twelve healthy volunteers underwent rapid magnetic resonance imaging after oral administration of a carbon dioxide generating agent using a combination of breath-hold and interactive fluoroscopic imaging during breathing. Diagnostic-quality images were obtained in 100% of cases for the stomach and in 92, 75, 67 and 42% of cases for the duodenal segments 1-4, respectively. Visualisation of the jejunum and ileum proved unacceptable for clinical use and anti-peristaltic agents did not significantly influence the results. Further development of fast imaging and magnetic resonance interactive fluoroscopic methods may allow the use of carbon dioxide as a contrast medium for clinical imaging of the stomach and duodenum.

    Transabdominal preperitoneal hernioplasty (TAPP) is a common procedure for groin hernia repair in adults. The peritoneal closure after mesh placement can be performed in various ways. In any case, thorough closure is recommended to avoid mesh exposure to the viscera with the risk of adhesions and bowel incarceration into peritoneal defects. Postoperative intestinal obstructions can mainly occur due to adhesions or bowel herniation through peritoneal defects into the dissected preperitoneal space. Incarcerations can also occur as a consequence of trocar site herniation. Recently barbed self-anchoring knotless suturing devices are frequently used for peritoneal closure. The correct handling of such sutures is crucial to avoid potential complications. Despite of accurate management, bowel adherence and injuries or volvulus can occur. We present an unusual case of a postoperative small bowel obstruction owing to strained adhesions and ingrowth between a small bowel segment and a polyglyconate unidirectional self-anchoring barbed suture device. Medline and PudMed databases were searched using the below-mentioned keywords and the literature on efficacy and safety of barbed sutures for peritoneal closure is reviewed as well as the usage of such devices in other fields of surgery.

    The aim was to compare bowel distension and diagnostic properties of magnetic resonance imaging of the small bowel with oral contrast (MRI per OS) with magnetic resonance enteroclysis (MRE). Forty patients with suspected Crohn's disease (CD) were examined with both MRI methods. MRI per OS was performed with a 6% mannitol solution and MRE with nasojejunal intubation and a polyethylenglycol solution. MRI protocol consisted of balanced fast field echo (B-FFE), T2 and T1 sequences with and without gadolinium. Two experienced radiologists individually evaluated bowel distension and pathological findings including wall thickness (BWT), contrast enhancement (BWE), ulcer (BWU), stenosis (BWS) and edema (EDM). The diameter of the small bowel was smaller with MRI per OS than with MRE (difference jejunum: 0.55 cm, p < 0.001; ileum: 0.35 cm, p < 0.001, terminal ileum: 0.09 cm, p = 0.08). However, CD was diagnosed with high diagnostic accuracy (sensitivity, specificity, positive and negative predictive values: MRI per OS 88%, 89%, 89%, 89%; MRE 88%, 84%, 82%, 89%) and inter-observer agreement (MRI per OS k = 0.95; MRE k = 1). In conclusion, bowel distension was inferior in MRI per OS compared to MRE. However, both methods diagnosed CD with a high diagnostic accuracy and reproducibility. (orig.)

    To determine whether specific magnetic resonance enterography (MRE) findings can predict outcome following commencement of antitumor necrosis factor (aTNF) in small bowel Crohn's disease (CD) PATIENTS AND METHODS: This was a single-centre retrospective study of patients with CD who commenced aTNF (infliximab or adalimumab) between 2007 and 2013. Patients who had an MRE within 6 months before commencing aTNF were included. The primary end-point was the need for CD-related surgery. The secondary end-points were time to surgery and time to treatment failure. The relationship between these end-points, clinical variables and specific MRE findings were studied. Four hundred and eighteen patients commenced aTNF for CD during the study period. Seventy-five patients had an MRE within 6 months before commencing aTNF (30 infliximab; 45 adalimumab). The median time from MRE to commencing aTNF was 43 days (IQR 19.5-87 days). Eighteen of 75 (24%) had surgery during a median follow-up of 16.7 months (IQR 9.0-30.1 months). Patients with small bowel stenosis (SBS) on MRE were at a significantly higher risk of requiring surgery: 12/18 (66.7%) versus 6/57 (10.5%) (P<0.001). Time to surgery was significantly shorter in patients with SBS on MRE (P<0.001). In a multivariate analysis, SBS (P<0.0001, hazard ratio 26.45, 95% confidence interval 5.45-128.49) and presence of penetrating complications (P=0.003, hazard ratio 36.53, 95% confidence interval 3.40-393.19) were associated independently with time to surgery. SBS and penetrating complications on MRE are associated independently with a need for early surgery and treatment failure in patients commencing aTNF.

     Probe-based confocal laser endomicroscopy (pCLE) enables real-time optical biopsy. Little is known about pCLE imaging deep inside the small bowel, therefore the aim of this study was to determine its usefulness.  Between April 2014 and January 2016, we performed 38 pCLE examinations during double-balloon enteroscopy with intravenous fluorescein in 37 patients with: tumors (n = 10), vascular disorders (n = 6), inflammatory diseases and drug injuries (n = 13), other disorders (n = 4), and normal findings (n = 4). We measured the calibers of capillary and lymphatic vessels at 15 different sites and compared the calibers between pCLE images and histopathology. We also compared pCLE findings with pathologic diagnosis.  The inner diameters of capillary vessels beneath the epithelium and in the middle of villi were 16.2 ± 3.0 µm and 14.5 ± 3.1 µm, respectively, in the pCLE images, but these were not consistent with formalin-fixed paraffin-embedded histology. In tumors, larger capillary vessels were observed in aggressive malignant lymphoma and metastasis, and a "soccer ball-like pattern" constituting homogenous dark cells packed with polygonal, narrower capillary vessels was characteristic in pCLE images of a malignant lymphoma follicle. Hereditary hemorrhagic telangiectasia and angiodysplasia contained anastomosis of capillary vessels of different calibers. In IgA vasculitis, segmental capillary strictures were observed. Intestinal lymphangiectasia with protein-losing enteropathy contained a reticular network of lymphatic vessels and dilated lymphatic ducts accompanied by numerous cell gaps. pCLE findings corresponded to pathologic diagnosis in 32 examinations (91 %).  pCLE is useful for in vivo analysis of abnormalities of the capillary and lymphatic vessels and epithelium, and for diagnosis in various small-bowel diseases.

    More than half of all congenital deformities can be detected in utero. The initial surgical correction is of paramount importance for the achievement of good long-term results with low surgical morbidity and mortality. Selective literature review and expert opinion. Congenital deformities are rare, and no controlled trials have been performed to determine their optimal treatment. In this article, we present the prenatal assessment, treatment, and long-term results of selected types of congenital deformity. Congenital diaphragmatic hernia (CDH) affects one in 3500 live-born infants, while esophageal atresia affects one in 3000 and small-bowel atresia one in 5000 to 10,000. If a congenital deformity is detected and its prognosis can be reliably inferred from a prenatal assessment, the child should be delivered at a specialized center (level 1 perinatal center). The associated survival rates are 60-80% after treatment for CDH and well over 90% after treatment for esophageal or small-bowel atresia. Despite improvements in surgical correction over the years, complications and comorbidities still affect 20-40% of the treated children. These are not limited to surgical complications in the narrow sense, such as recurrence, postoperative adhesions and obstruction, stenoses, strictures, and recurrent fistulae, but also include pulmonary problems (chronic lung disease, obstructive and restrictive pulmonary dysfunction), gastrointestinal problems (dysphagia, gastro-esophageal reflux, impaired intestinal motility), and failure to thrive. Moreover, the affected children can develop emotional and behavioral disturbances. Minimally invasive surgery in experienced hands yields results as good as those of conventional surgery, as long as proper selection criteria are observed. Congenital deformities should be treated in recognized centers with highly experienced interdisciplinary teams. As no randomized trials of surgery for congenital deformities are available, longitudinal

    To evaluate the adequacy of the study of iron deficiency anemia (IDA) in real life practice prior to referral to a gastroenterology department for small bowel evaluation. All consecutive patients referred to a gastroenterology department for small bowel investigation due to iron deficiency anemia, between January 2013 and December 2015 were included. Both patients referred from general practitioners or directly from different hospital departments were selected. Relevant clinical information regarding prior anemia workup was retrospectively collected from medical records. An appropriate pre-referral study was considered the execution of esophagogastroduodenoscopy (EGD) with Helicobacter pylori ( H. pylori ) investigation, colonoscopy with quality standards (recent, total and with adequate preparation) and celiac disease (CD) screening (through serologic testing and/or histopathological investigation). A total of 77 patients (58.4% female, mean age 67.1 ± 16.7 years) were included. Most (53.2%) patients were referred from general practitioners, 41.6% from other hospital specialties and 5.2% directly from the emergency department. The mean pre-referral hemoglobin concentration was 8.8 ± 2.0 g/dL and the majority of anemias had microcytic (71.4%) and hypochromic (72.7%) characteristics. 77.9% of patients presented with an incomplete pre-referral study: EGD in 97.4%, with H. pylori investigation in 58.3%, colonoscopy with quality criteria in 63.6%, and CD screening in 24.7%. Patients with an appropriate study at the time of referral were younger (48.7 ± 17.7 vs 72.3 ± 12.3 years, P anemia prior to referral to gastroenterology department is unsatisfactory. Only approximately a quarter of patients presented with an appropriate study.

    This thesis describes some aspects of short bowel syndrome. When approximately 1 m or less small bowel is retained after extensive resection, a condition called short bowel syndrome is present. Since the advent of parenteral nutrition, the prognosis of patients with a very short bowel has dramatically improved. Patients with 40 to 100 cm remaining jejunum and/or ileum can generally be maintained with oral nutrition due to increased absorption of the small bowel remnant as result of intestinal adaptation. This study reports clinical, biochemical and nutritional aspects of short bowel patients on oral or parenteral nutrition, emphasizing data on absorption of various nutrients and on bone metabolism. Furthermore, some technical apsects concerning long-term parenteral nutrition are discussed. (Auth.)

    Full Text Available Objectives. Small bowel capsule endoscopy (SBCE plays a decisive role in the obscure gastrointestinal bleeding (OGIB diagnosis. Antithrombotics may increase bleeding risk in patients with preexistent lesions or through direct mucosal aggression. We aimed to correlate antithrombotics usage with lesions with bleeding potential found in SBCE. Methods. Retrospective single-center study including 274 consecutive SBCE performed over 7 years for OGIB. The lesions were classified as P0 (no bleeding potential, P1 (uncertain bleeding potential: erosions, and P2 (high bleeding potential: angioectasias, ulcers, and tumors. We assessed antiplatelet and anticoagulant drug use during the 60 days preceding SBCE. Results. One-third of the patients were under antithrombotic therapy. The diagnostic yield of SBCE for P2 lesions was 30.0%. Angioectasias (20.4% were the most frequently observed lesions. There was a significant correlation between anticoagulant drug use and a higher incidence of P2 lesions in the small bowel (43.2% versus 26.5%; OR = 2.11, P=0.026. We found no significant correlation between antiplatelets and lesions with bleeding potential in SBCE. Conclusions. Small bowel lesions with high bleeding potential were more frequently detected when the patient was on anticoagulant drugs, resulting in a twofold risk. Antiplatelet drugs were not associated with small bowel lesions.

    SmartPill(®) (Given Imaging Corp.,Yoqneam,Israel) is an ingestible, non-imaging capsule that records physiological data including contractions and pH throughout the gastrointestinal tract. There are scarce data looking at SmartPill(®) assessment of patients with known/suspected small-bowel Crohn's Disease (CD). This pilot study aims to investigate feasibility and safety of SmartPill(®) to assess gut motility in this group.  Over 1 year, patients with known/suspected CD, referred for small-bowel capsule endoscopy (SBCE), were invited to participate and 12 were recruited (7 female, 5 male, mean age 44.2 ± 16.6 years). They underwent hydrogen breath test to exclude small-bowel bacterial overgrowth, patency capsule (Agile(®)), and provided stool samples for fecal calprotectin (FC). Patients ingested PillCam(®)SB2 and SmartPill(®) 4 hours apart. Using unpublished data, 33 healthy controls also were identified for the study. P capsules. Limitations included transient Smartpill(®) signal loss (5/10 studies). This is the first pilot to attempt combining SBCE and SmartPill(®) to assess small-bowel CD. Data on motility in CD are scarce. Multimodal information can provide a clearer clinical picture. Despite concerns about capsule retention in CD patients, SmartPill(®) seems safe for use if a patency capsule is employed beforehand.

    Incidence of acute grade 3 and 4 small bowel toxicity in the definitive treatment of cervical cancer is approximately 15%. Given uncertainties in position of the bowel at time of treatment, techniques including the contouring of a bowel bag have been suggested. The purpose of this study is to describe interfraction variability in bowel location for the female pelvis with intact reproductive organs and to characterize the ability of the bowel bag technique, as described in the Radiation Therapy Oncology Group pelvic normal tissue contouring guidelines, to account for organ motion in this specific clinical setting. Bowel position was assessed for 45 computed tomographic scans used in treatment planning for 9 consecutive cervical cancer patients. After a single operator contoured bowel loops, most superior, anterior, posterior, and inferior positions of bowel were recorded. Mixed effects models were used to assess significance of interfraction variability. Frequency of bowel loop migration outside of the bowel bag was then considered for each patient given all potential bowel bag volumes. Standardized scoring was used to determine additional margins that would be required to account for 95%, 9
