1/53. Giant colonic diverticulum: report of a case.

    Giant colonic diverticulum is a rare complication of colonic diverticulosis. It typically occurs as a single diverticulum located on the antimesenteric border of the sigmoid colon. The most widely accepted theory for its development attributes the progressive dilation to a "ball-valve" mechanism, allowing air to enter but not to exit. patients usually present complaining of abdominal pain and/or an abdominal mass, although they may remain asymptomatic. physical examination reveals a tympanic abdominal mass that appears as a round radiolucency on plain radiographs and CT. barium enema demonstrates the relationship of the diverticulum to bowel and may document communication with the colonic lumen. To alleviate symptoms and prevent complications, the recommended treatment is excision of the diverticulum in continuity with the involved colonic segment. We report a case and discuss the presentation, diagnosis, and management of giant colonic diverticulum.

2/53. Malignant peritoneal mesothelioma with mimicry of pseudomyxoma peritonei in a patient with a history of perforated sigmadiverticulitis.

    We describe a 57-year-old man who presented with diffuse abdominal pain, abdominal enlargement, vomitus, dyspnea and a weight loss of 30 kg within 6 months. These acute symptoms were preceded by an episode of ascites and an acute sigmadiverticulitis 7 months ago. ultrasonography and computed tomography were suggestive of pseudomyxoma peritonei. However, malignant mesothelioma peritonei was diagnosed by open surgery with biopsy for histological examination. Despite R-2-resection of the tumor and following open hyperthermic intraperitoneal chemotherapy with initial remarkable recovery the patient died 5 months after therapeutical intervention. Malignant peritoneal mesothelioma is an extremely rare tumor with great diagnostic and therapeutic difficulties. We report a case including diagnostical work up and the medical surgical therapy of this disease.

3/53. 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.

4/53. 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.

5/53. 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.

6/53. diverticulitis causing a high serum level of carbohydrate antigen 19-9: report of a case.

    We report herein a rare case of diverticulitis causing a high serum level of carbohydrate antigen (CA) 19-9. A 52-year-old man was admitted to our hospital with lower abdominal pain. Laboratory data showed evidence of inflammation and a high serum level of CA 19-9 (370 U/ml). Computed tomography demonstrated thickening of the wall of the sigmoid colon. He was diagnosed as having diverticulitis of the sigmoid colon and was treated with antibiotics. Although his symptoms improved, the presence of a malignancy such as colorectal cancer could not be completely ruled out because of the persistently high serum level of CA 19-9. A laparotomy was performed and the sigmoid colon was found to be adherent to the bladder. Under a diagnosis of diverticulitis, a sigmoidectomy was performed. Pathological examination revealed diverticulitis of the sigmoid colon, but there was no evidence of malignancy in the resected specimen. The serum CA 19-9 level decreased to normal postoperatively and immunohistochemical staining revealed CA 19-9 antigen in the cytoplasm of the diverticular epithelium. Therefore, a possible explanation for the high level of this tumor marker was diverticulitis of the sigmoid colon.

7/53. An unusual perforation of the colon: report of two cases.

    We herein present two cases of a colorectal perforation due to uncommon reasons. First, we treated a 45-year-old woman for a stercoral perforation of the sigmoid colon. The pathognomonic etiology was a barium fecaloma originating from an upper gastrointestinal series 9 months before admission. The second case was a 46-year-old woman who was admitted with a perforation of the transverse colon. She had experienced perforations of the sigmoid colon at 32 years of age and of the rectum at 44 years of age, respectively. The second and third conditions were diagnosed to be idiopathic, and were histologically proven by an abrupt obliteration and a thinness of the colonic wall with some infiltration of inflammatory cells. The first condition, however, was most likely a stercoral perforation. The postoperative course of these patients was uneventful, and both are doing well at this writing.

8/53. Laparoscopic segmental resection of the sigmoid and rectosigmoid colon for endometriosis.

    patients with symptomatic endometriosis of the colon and distal small bowel usually present with crampy abdominal pain, pelvic and rectal pain, constipation, and dyspareunia. Superficial disease can be easily resected laparoscopically with scissors. Deeper lesions require full-thickness resection and closure of the bowel. Occasionally deep, large, or multiple lesions will require segmental resection for adequate control of the disease. Five patients with intestinal endometriosis underwent attempted laparoscopic segmental colon resection. Two patients required conversion to open laparotomy because of difficulty with the anastomosis. No operative complications or deaths occurred in this group. Those patients undergoing laparoscopic colectomy showed return of bowel function within 24 to 48 h and were discharged home on postoperative day 4.

9/53. Laparoscopic-assisted sigmoid colectomy for sigmoid volvulus.

    A 75-year-old black man came to the emergency room because of nausea, vomiting, abdominal pain, and distension and obstipation. An abdominal radiograph revealed a sigmoid volvulus. This was nonoperatively reduced in the emergency room. Following a mechanical and antibiotic bowel preparation, the patient underwent elective exploration. We report, for the first time, operative treatment of sigmoid volvulus with a laparoscopic-assisted sigmoid colectomy and primary anastomosis. Because of dense fibrous scarring of the sigmoid mesentery produced by chronic mesosigmoiditis, the redundant sigmoid was exteriorized and resected extracorporeally. A stapled, side-to-side, functional end-to-end anastomosis was constructed. The patient experienced little postoperative pain and virtually no postoperative ileus. We believe that laparoscopic-assisted sigmoid resection may offer distinct advantages for the treatment of the typically elderly, debilitated patient in whom sigmoid volvulus develops. Furthermore, because of the characteristic mesosigmoiditis associated with sigmoid volvulus, we suspect that exteriorization and extracorporeal resection may prove the easiest and most rapid laparoscopic approach to this disease.

10/53. Stercoraceous perforation of the sigmoid colon: report of two cases.

    Stercoraceous perforation of the sigmoid colon has rarely been reported in the literature. This lesion is assumed to be produced by the pressure from a hard scybalum resulting in a perforated ulcer with necrotic edges. Two cases of stercoraceous perforation of the sigmoid colon are presented in this paper. It is difficult to diagnose this lesion preoperatively, although ultrasonograms proved useful in showing the colon perforation. This lesion should always be suspected when a patient who has had chronic constipation presents with sudden severe abdominal pain. It is possible that this lesion is becoming more common as the mean age of the population increases and we stress the importance of immediate surgery and intensive care for improving the prognosis.
