31/373. Volvulus of the transverse and sigmoid colon. A case of transverse and sigmoid-colon volvulus and a discussion of the probable mechanism of large-bowel volvulus (LBV) in children and its management is presented. A 5-year-old male with cerebral palsy presented with transverse-colon and subsequently sigmoid volvulus. The child underwent resection of the involved segments with primary colocolic and colorectal anastomosis, respectively. The recovery was uneventful. LBV in children is due to congenital anomalous or absent ligamentous fixation of the colon. constipation is probably the result of the volvulus. Resection of the involved segment and primary anastomosis is the definitive treatment. ( info) |
32/373. Surgical treatment of a sigmoid volvulus associated with megacolon: report of a case. Sigmoid volvulus occurring concomitantly with megacolon is an uncommon cause of bowel obstruction, and various approaches to treatment have been proposed. We report herein a case of sigmoid volvulus with megacolon that was successfully treated by elective surgery following endoscopic reduction during the same hospital stay. A 70-year-old woman was admitted to our hospital with abdominal pain, distension, and severe constipation. physical examination, plain abdominal X-ray, and barium enema confirmed a sigmoid volvulus and further examinations revealed concomitant megacolon. An elective sigmoid colectomy was performed following successful endoscopic decompression. The postoperative course was uneventful and there was no residual colonic dysmotility. Histologically, no aganglionic tissue was observed in the resected specimen. ( info) |
33/373. Recurrent intussusception of the sigmoid colon caused by a transanal protruding sessile tubulo-villous malignant polyp. We report a case of a 35 year-old woman with a large malignant sessile tubulo-villous polyp of the proximal end of a dolico-sigmoid colon causing intussusception and transanal prolapsing. The diagnosis presented some difficulties being the intussusception intermittent. The clinical feature had been initially misdiagnosed for a very large bleeding polyp (5 cm in size), protruding out of the anus with a long pedicle in the rectum. The histology of multiple bioptic samples of the lesion revealed malignancy. Conventional radiologic studies (plain x-rays, barium enema) after metal clips had been placed on the head of the polyp before it rose up the colon, led to the correct diagnosis without, nevertheless, documenting intussusception. An elective surgical resection of the dolico-sigmoid colon allowed the correct diagnosis and the curative treatment of the colonic intussusception and the malignancy. ( info) |
34/373. diagnosis and treatment of sigmoidal endometriosis--a case report. Intestinal endometriosis is a rare but clinically significant complication. The most commonly involved sites are the rectosigmoid (up to 73%) and rectovaginal septum (13%). A case of a 53-year-old woman with intestinal endometriosis located in the sigmoid colon is presented with symptoms of pelvic pain and rectal bleeding. The diagnosis was established by means of colonoscopy which was performed 3 times before laparotomy. Bowel resection and pathologic study are necessary to relieve the symptoms and avoid neglecting a malignant tumor or other lesions. The postoperative course was uneventful and the patient was discharged after 13 days. ( info) |
35/373. Sigmoid volvulus in children: report of two cases. Volvulus of the sigmoid colon is rare in children. An early, accurate diagnosis can avoid unnecessary surgery and reduce the risk of complications. This condition is mainly due to a redundant sigmoid colon with a narrow mesosigmoid attachment. We describe two cases of sigmoid volvulus, which showed different clinical severities and were treated with different methods. Patient 1, a 9-year-old boy, presented with acute abdominal pain and vomiting. Patient 2, an 11-year-old boy, presented with abdominal pain, abdominal distention, and bloody mucoid stool. Plain abdominal radiographs revealed a distended colonic loop extending upward from the pelvis in patient 1 and a typical "coffee bean" sign in patient 2. barium enema examination was used to confirm the diagnosis in both cases. The volvulus was reduced by insertion of a rectal tube in patient 1 and surgically in patient 2. Sigmoid colon volvulus should be included in the differential diagnosis of childhood abdominal pain or distention. This report suggests that nonsurgical reduction should be attempted first for uncompromised sigmoid volvulus in children, unless bowel ischemia or perforation develops. ( info) |
36/373. Neonatal sigmoid volvulus: a complication of anal stenosis. Sigmoid volvulus is an exceptionally rare cause of intestinal obstruction in neonates. Only 7 cases have been reported in the English and French literature. The authors report a recent case of sigmoid volvulus in a neonate secondary to anal stenosis and review the diagnosis and management of this serious condition. The authors believe that carefully performed radiologic reduction is the preferable alternative to surgical intervention. ( info) |
37/373. arthritis as a rare extra-intestinal manifestation of acute sigmoid diverticulitis. BACKGROUND: A causal association between acute diverticulitis of the sigmoid colon and arthritis has rarely been reported. CASE REPORT: We report the case of a 60-year-old patient who developed migrating arthritis of the knee and ankle during the recurring episode of acute diverticulitis of the sigmoid colon. Treatment with NSAIDs and antibiotics had little effect on joint disease, but medical treatment was successful in reducing the diverticulitis-related symptoms. arthritis promptly improved after surgical resection of the sigmoid colon, and 30 months later the patient is free of symptoms in the previously affected joints. CONCLUSIONS: Five cases of diverticulitis-associated arthritis have been reported. The similar case reported here reconfirms that joint disease has a limited response to medical approaches. Colon resection is recommended for patients with diverticulitis-associated arthritis which does not respond promptly to antibiotic therapy. ( info) |
38/373. 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. ( info) |
39/373. Colonic necrosis subsequent to catheter-directed thrombin embolization of the inferior mesenteric artery via the superior mesenteric artery: a complication in the management of a type II endoleak. The optimal management of endoleaks after endovascular repair of abdominal aortic aneurysms remains to be established. In this report, we describe a persistent side-branch, or type II, endoleak 1 year after endograft implantation treated with catheter-directed embolization of the aneurysm sac and the inferior mesenteric artery via the superior mesenteric artery, with embolization agents including thrombin, lipiodol, and gelfoam powder. Shortly after the embolization procedure, colonic necrosis developed in the patient, manifested by peritonitis, which necessitated a partial colectomy. This case underscores the devastating complication of colonic ischemia as a result of catheter-directed embolization of the inferior mesenteric artery in the management of an endoleak. ( info) |
40/373. Delayed colon perforation after palliative treatment for rectal carcinoma with bare rectal stent: a case report. In order to relieve mechanical obstruction caused by rectal carcinoma, a bare rectal stent was inserted in the sigmoid colon of a 70-year-old female. The procedure was successful, and for one month the patient made good progress. She then complained of abdominal pain, however, and plain radiographs of the chest and abdomen revealed the presence of free gas in the subdiaphragmatic area. Surgical findings showed that a spur at the proximal end of the bare rectal stent had penetrated the rectal mucosal wall. After placing a bare rectal stent for the palliative treatment of colorectal carcinoma, close follow-up to detect possible perforation of the bowel wall is necessary. ( info) |
