1/5. Percutaneous endoscopic sigmoidopexy in sigmoid volvulus with T-fasteners: report of two cases.PURPOSE: We report two cases of percutaneous endoscopic sigmoidopexy in patients with sigmoid volvulus. methods: Two patients with recurrent sigmoid volvulus were considered unfit for resective surgery or general anesthesia (American Society of Anesthesiologists physical status III-IV). Fixation of the sigmoid colon to the abdominal wall was performed percutaneously under sedation in the endoscopy suite. Fixation was obtained using three T-fasteners in a triangular disposition in the bowel. The T-fasteners were cut at the skin after 28 days. RESULTS: Both procedures were successfully performed in approximately 20 minutes and were well tolerated. Feeding commenced the same day. One patient died after seven months of follow-up, without recurrence, of causes not related to volvulus. The other patient had no recurrence after 18 months of follow-up. CONCLUSION: The authors purpose was to show a new technique for colonic fixation performed in patients with recurrent sigmoid volvulus who otherwise had contraindication for elective surgery. Future studies will be required to verify the effectiveness and safety of this novel technique.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/5. Contrast-enhanced three-dimensional magnetic resonance angiography for visualization of ectopic varices.We report the case of a 62-year-old male with portal hypertension and recurrent bleeding refractory to surgical intervention from varices in a sigmoid stoma. Although stomal varices were detected neither by physical examination, stomal endoscopy, nor duplex sonography, contrast-enhanced three-dimensional magnetic resonance angiography of the portal vein and its collateral branches demonstrated their presence. Surgical revisions of the stoma failed to prevent bleeding, but implantation of a transjugular intrahepatic shunt successfully prevented recurrent hemorrhage. This case indicates that contrast-enhanced, three-dimensional magnetic resonance angiography is useful to detect this rare complication of portal hypertension and helps to tailor adequate treatment in patients with recurrent bleeding from stomal varices.- - - - - - - - - - ranking = 15.626596942281keywords = physical examination, physical (Clic here for more details about this article) |
3/5. Stercoral perforation of the sigmoid colon: report of a rare case and its possible association with nonsteroidal anti-inflammatory drugs.Stercoral perforation of the colon is a rare phenomenon with fewer than 90 cases reported in the literature to date. The pathogenesis of stercoral ulceration is thought to result from ischemic pressure necrosis of the bowel wall caused by a stercoraceous mass. Stercoral perforation in more than 90 per cent of cases involves the sigmoid or rectosigmoid colon with associated fecal mass causing localized mucosal ulceration and bowel wall thinning due to localized pressure effect. We report the case of a 45-year-old woman who presented with a 12-hour history of epigastric pain. Significant comorbidities included systemic lupus erythematosus, sarcoidosis, hypertension, and previous history of congestive heart failure. The patient was also on prednisone and a nonsteroidal anti-inflammatory drug for joint pains. On physical examination the patient had signs of generalized peritonitis. Chest X-ray showed significant free air under the diaphragm. Emergency laparotomy revealed localized perforation over the antimesenteric border of the sigmoid colon with associated stercoral mass at the site of perforation. A segmental resection of the sigmoid colon with end colostomy (Hartmann's procedure) was performed. The patient made an uneventful recovery. Stercoral perforation is often a consequence of chronic constipation; however, there are other predisposing factors as the condition is rare compared with the frequency of severe constipation. One of the hypotheses includes the association of nonsteroidal anti-inflammatory drugs (NSAIDs) with stercoral perforation of the colon. Our case report lends support to this association with NSAID use; thus there need to be greater awareness and caution when using NSAIDs in chronically constipated patients.- - - - - - - - - - ranking = 15.626596942281keywords = physical examination, physical (Clic here for more details about this article) |
4/5. Ileosigmoid knotting: a case report and review.Ileosigmoid knotting, or compound volvulus, has not been reported previously in australia. A 41 year old woman of Anglo-Saxon origin presented with a short history of extreme abdominal pain that was out of proportion to her physical findings. At operation it was found that her entire ileum was tightly knotted around the redundant, twisted sigmoid colon. Both closed loops were gangrenous and it was impossible to unravel the bowel. She recovered uneventfully following resection and primary anastomosis of both portions of the intestine. Most patients with this uncommon condition have been reported from finland and eastern africa. An arrangement of the small bowel and sigmoid colon on long, narrow mesenteries would appear to be a prerequisite. The brevity of the history and the severity of the abdominal pain call for early laparotomy. Prolonged attempts to untie the knot are dangerous. It is safer to divide the ileum at the knot and resect it in order to release the sigmoid colon. Primary anastomosis is feasible where the history is short and the uninvolved intestine is clean and collapsed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/5. Sigmoid perforation by compressed carbon dioxide.Self-induced injuries of the bowel have various accidental mechanisms. This is a report of a 35-year-old patient with disruption of the recto-sigmoid junction caused by carbon dioxide (CO2) originating from a bottle of sparkling wine, which was introduced transanally for sexual stimulation. The patient underwent resection of the recto-sigmoid junction and primary anastomosis. The postoperative course was uneventful except for wound infection. The patient was discharged 12 days later. The physical backgrounds, the pathological pathways for perforation and diagnostic modalities including diagnostic pitfalls are critically discussed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
