Massive hemorrhage from diverticular disease of the colon is a very difficult problem in abdominal emergency surgery. The pathogenesis of bleeding colonic diverticulosis is strictly correlated to the angioarchitecture of the colonic diverticular wall. Here the vasa recta penetrate the colonic wall from the serosa to the submucosa through connective tissue septa. Injurious factors arising from the colonic or diverticular lumen can produce an eccentric damage to the luminal side with intimal thickening, segmental weakening of the artery and its rupture with massive bleeding. Conventional barium enema is not able to show the source of the hemorrhage in the majority of the bleeding patients; colonoscopy, as primary emergency procedure, has significant positive findings in 41.5%-83.7% of patients. Radionuclide bleeding scans have a sensitivity rate of 86%-94%. Emergency arteriography localizes the bleeding source in higher rates ranging from 58% to 86% and is successful after intraarterial infusion of vasopressin or embolization in 47%-92% of patients. Surgical treatment for continued bleeding from diverticular disease is controversy. Segmental resection should be performed on patients with localized bleeding sources (positive arteriogram). Laparotomy, anterograde irrigation and intraoperative colonoscopy are indicated in patients with multiple bleeding sites and negative arteriography. Because the right colon is the most common site of bleeding in same cases is necessary to perform a subtotal colectomy with ileorectal anastomosis. Blind resections particularly in the elderly patients present high rebleeding rate (> 60%) and high mortality (30%) with sepsis accounting for the majority of deaths.

We treated 65 children with proven Hirschprung's disease between 1970-1992. After definitive surgery, 35 were over 10 years of age and 13 were over 18. The male:female ratio was 4:1. All but 3 were born full-term. 44% were of Bedouin origin, with a higher prevalence in 3 families of 2 tribes. 38 (58%) were diagnosed in the neonatal period: by barium enema and rectal muscle biopsy in 42 (65%), and by barium enema alone in 23 (35%). In the latter the diagnosis was verified by intra-operative biopsy. Severe constipation, intestinal obstruction or enterocolitis were the presenting features. 19 associated anomalies were found in 12 children, but none was life-threatening; 5 (8%) had cardiac anomalies; none had Down's syndrome. The rectosigmoid colon was the most common aganglionic segment involved (only 1 had total colonic aganglionosis). 7 of the 8 with short segment involvement responded well to posterior rectal myectomy. 55 patients had an abdominoperineal pull-through: 48 by Swenson's procedure and 5 by the Soave and 2 by the Duhamel modifications. In 43 a protective colostomy was performed at the end of the procedure. 53 had complete diversion colostomy at the time of initial diagnosis (neonatal and early infancy). There was no intra- or immediate post-operative death. 1 patient died 2 months after operation of complications following enterocolitis and total parenteral nutrition. 2 died a few hours after admission of severe sepsis due to enterocolitis before operation was possible. There were early postoperative complications in 11% of the 151 operations, mostly minor wound infections.(ABSTRACT TRUNCATED AT 250 WORDS)

Enterovesical fistula is a rare complication of pelvic radiotherapy. Recurrent disease is the cause of fistulization in most patients. We identified 14 patients who developed enterovesical fistula in the absence of tumor recurrence. These women were at high risk for radiation morbidity due to prior surgery, pelvic inflammatory disease, adjuvant hyperbaric oxygen, or locally high doses of radiotherapy caused by suboptimal geometry and technique. All patients underwent radiographic imaging including barium enema, intravenous pyelogram, and upper gastrointestinal study with small bowel follow-through. The range of radiation morbidity was great: some patients had small fistulae, others had extensive fistulization and radionecrosis. Six patients had colovesical fistulae, five had enterovesical fistulae, and three had fistulae involving both the small and large bowel. Twelve patients underwent 13 surgical procedures. Healing or successful repair of the fistula was achieved in 1 of 3 patients treated with diversion (loop colostomy), 2 of 4 patients treated with isolation of the fistulized bowel loop and urinary conduit, and 5 or 6 treated with bowel resection with or without urinary conduit. Two of three perioperative deaths occurred in the isolation group managed without urinary conduit and were related to ongoing sepsis. Surgical procedures which resect necrotic fistulized bowel and result in complete separation of the gastrointestinal and genitourinary tracts provided the best results in patients with radiation-induced enterovesical fistulae. CT scan of the abdomen and pelvis is recommended in the evaluation of the majority of patients with suspected enterovesical fistula.

Malrotation of the intestinal tract is a product of a well defined aberrant embryology. Because the consequences of malrotation associated with a midgut volvulus may be catastrophic, an understanding of the anatomy, diagnostic criteria, and appropriate therapy for this putative emergency illness is imperative. This report summarizes a recent 18-month experience with this diagnosis and contrasts this experience with that in the published literature. More than half (14/22) of the patients presented during the first month of life, and all had vomiting, which in most cases was bilious. The barium upper gastrointestinal series was the preferred diagnostic study, being both sensitive (18/19, 95%) and accurate (18/21, 86%). In this series two-thirds of the patients presented with volvulus (15/22, 68%) of whom five had ischemic intestine requiring resection. One of these children died of overwhelming sepsis. A Ladd procedure was the preferred treatment, which as defined by us includes evisceration and inspection of the mesenteric root, counterclockwise derotation of a midgut volvulus, lysis of Ladd's bands with straightening of the duodenum along the right abdominal gutter, inversion-ligation appendectomy, and placement of the cecum into the left lower quadrant. A high index of suspicion in the neonate with vomiting, rapid diagnosis, and appropriate operative therapy results in a predictable favorable outcome for children with intestinal malrotation.

Spontaneous retroperitoneal abscess as a result of Crohn's disease does not always terminate at the psoas or iliac spaces. The abscess may continue downward breaching the obturator fascia. Passage through the sciatic foramina can result in a buttock or posterior upper thigh abscess. This possibility is illustrated in the case presented by a 40 year old female with toxemia and a fluctuant mass in the right gluteal area. Surgical drainage and control of the sepsis was followed by enterocutaneous fistula formation. Small bowel barium series demonstrated communication of the tracking abscess with the caput cecum. Surgical management consisted of formal ileocolectomy. The pathology report revealed Crohn's disease of the terminal ileum and right colon.

Esophageal fistula may involve the respiratory or cardiovascular system. Fistulas involving the respiratory system which originate from esophageal cancers are the most common. Diagnosis is best made with barium esophagogram. ERF of any cause usually leads to repetitive contamination of the respiratory tract, resulting in sepsis and death of the patient if untreated. In the case of MERF, whether from esophageal or lung cancer, only palliative treatment is usually possible. Better results, including cure, may be expected when a MERF is caused by lymphoma. Curative operation with closure of the fistula is usually possible for BERF if the fistula is identified and treated before irreversible damage has been done by infection, sepsis, and malnutrition. Esophagocardiovascular fistulas occur infrequently in comparison with ERF. These may involve the aorta, usually as a result of a thoracic aneurysm. Rarely one may encounter esophageal fistula to the pericardium or heart. Few survivors have been reported, but successful management is possible if early diagnosis is made and prompt surgical management is undertaken.

In adults, toxic megacolon is a relatively uncommon but potentially lethal complication of inflammatory bowel disease (IBD), infectious colitis, or ischemic colitis caused by cancer chemotherapeutic agents. Patients have distension of the colon and signs of toxicity such as elevated temperature, hypotension, decreased level of consciousness and electrolyte imbalances. Factors thought to increase the risk include premature discontinuation of IBD medications; procedures that increase colon trauma, such as barium enema and colonoscopy; medications that decrease gastrointestinal motility; and electrolyte imbalances, especially hypokalemia. Differential diagnosis is made based on the patient's history and results of stool cultures and assay for Clostridium difficile toxin. Medical management in the intensive care unit includes careful monitoring, fluid volume and electrolyte replacement, bowel rest and decompression, antibiotic therapy, and cessation of medications that slow gastric motility. Surgical management may be necessary if there are signs of deterioration, perforation, hemorrhage, or sepsis.

A 51-year-old woman underwent emergency laparoscopic cholecystectomy. Stone loss occurred during gallbladder dissection. Histology showed empyema of the gallbladder. Postoperatively, she developed a subhepatic abscess that required percutaneous drainage. Two years after surgery, she re-presented with a right paracolic abscess. Transsciatic CT-guided drainage of the abscess was performed. Barium enema excluded colonic pathology. Two weeks later, she developed a right gluteal abscess deep to the recent drain site. Ultrasound-guided drainage was performed followed by a sonogram. The sonogram ruled out communication with the peritoneum. Two further subhepatic abscesses occurred during the next 5 years; the first abscess was drained percutaneously, but the second required open drainage: At laparotomy, gallstone fragments were found within the abscess cavity. The site of the previous gluteal drain continued to discharge intermittently. An MRI scan showed an uncomplicated sinus track. Subsequent sinography of the right gluteal track demonstrated an opacity at the apex of the sinus. The sinus was laid open and a gallstone retrieved. The patient has remained well for 3 years. Complications due to gallstone spillage generally manifest themselves shortly after surgery. This case demonstrates that lost stones may cause chronic abdominal and abdominal wall sepsis. In cases of chronic abdominal sepsis after laparoscopic cholecystectomy, the possibility of lost stones should be considered even if stones are not positively shown on imaging.

The age peak for acute appendicitis is between 10 and 20 years. Although older persons more rarely develop appendicitis, in the group of over-45-year-olds the perforation and mortality rates are appreciably higher. The reason for this is the fact that in the elderly, the symptoms are often veiled, so that the diagnosis is delayed. A particular role in this connection is played by pain killers and non-specific findings. In particular, however, the commonly present co-morbidity in older patients with appendicitis often leads to recalcitrant infections, and not infrequently to sepsis with a potentially fatal outcome. For the establishment of the diagnosis, therefore, a careful physical examination and thorough history-taking, together with a comprehensive laboratory work-up is essential. Imaging procedures such as X-rays of the abdomen, ultrasonography and, where indicated, such further measures as a barium enema or a CT scan may help establish the diagnosis in patients with unclear clinical symptoms, and thus prevent perforation.

The principal complications of continuous ambulatory peritoneal dialysis (CAPD), namely malposition of the dialysis catheter, peritonitis, exit site infection, leakage of dialysis fluid, sclerosing peritonitis, and renal cysts and tumors, are considered in this article. The techniques that are used to reposition displaced dialysis catheters and extend the duration of dialysis are described. The role of imaging in establishing the diagnosis of peritonitis is relatively small. However, both computed tomography (CT) and ultrasound may be used to identify loculation of fluid and localized sites of sepsis, and permit percutaneous drainage. Ultrasonography of the catheter track through the percutaneous tissues allows identification of pericatheter collections in patients with exit-site infection. The technique of CT peritoneography is helpful in establishing sites of dialysis fluid leakage. These commonly occur at the site of entry of the dialysis catheter, through abdominal incisions, or along the patent tunica vaginalis into the scrotum. The appearances on CT of sclerosing peritonitis reflect pathologic changes and are characterized by the presence of peritoneal thickening and calcification. Bowel obstruction, which may develop in sclerosing peritonitis, can be identified on abdominal radiographs or barium studies of the gastrointestinal tract. Acquired renal cystic disease and renal carcinomas occur in a significant proportion of patients undergoing CAPD. Ultrasound is the investigation of first choice in the identification and clarification of the pathology (cystic or solid) of suspected renal masses.
