Small bowel volvulus is an uncommon but important cause of small intestinal obstruction. It often results in ischemia or even infarction. Delay in diagnosis and surgical intervention increases morbidity and mortality rates. Based on cause, small bowel volvulus can be divided into primary and secondary type. Goals for treatment of small bowel volvulus should include physician awareness of this uncommon diagnosis, accurate workup, and advanced surgical intervention. The presentation and subsequent management of 35 patients with small bowel volvulus confirmed by laparotomy are reviewed and discussed. The incidence of small bowel volvulus in the adult European and North American is low. The resultant mortality rate, however, makes diagnosis critically important. The cardinal presenting symptom is abdominal pain. There is no single specific diagnostic clinical sign or abnormality in laboratory or radiologic finding. In practice, the diagnosis can only be made by laparotomy. The failure to perform an exploratory laparotomy cannot be justified. Early diagnosis and early surgery are the keys for successful management of strangulation obstruction of the small bowel.

The records of eight patients treated for intestinal obstruction resulting from bands that have no identifiable embryologic or acquired basis were reviewed retrospectively. All patients presented with symptoms and signs indicative of intestinal obstruction. Patients older than 2 years of age additionally had a history of chronic abdominal pain. One thick anomalous congenital band with blood vessels in it was found to be the cause of obstruction in each patient. Bands were located between ascending colon and terminal ileum in four patients (50%), ligament of Treitz and terminal ileum in two patients (25%), right lobe of liver and terminal ileum in one patient (12.5%), and right lobe of liver and ascending colon in one patient (12.5%). The obstructive mechanisms were compression of bowel by band in five patients (62.5%) and entrappment of an intestinal loop between the band and mesenterium in three patients (37.5%). These bands are suggested to be the anomalies of mesenterium that may cause intestinal obstruction and chronic abdominal pain in children.

Intestinal malrotation may be complicated by volvulus and intestinal necrosis. One hundred two children (64 male, 38 female) undergoing surgical abdominal exploration from 1977 to 1987 had malrotation. Fifty-two patients were less than 7 days of age, 13 from 8 to 30 days, 26 from 31 to 365 days, and 11 were older than 1 year of age. Of infants, 39 of 65 had 40-week gestations, 18 of 65 had 36- to 39-week gestations, and 8 of 65 had less than 36-week gestations. Chief symptomatology included: bilious emesis (47), intestinal obstruction (19), abdominal pain (11), and bloody stools (7). Seventy patients had congenital anomalies (50 single, 20 multiple). Diagnostic evaluations included 56 upper gastrointestinal series and 27 barium enemas. Each patient underwent correction of malrotation and appendectomy, and correction of congenital anomalies (omphalocele-9, gastroschisis-6, diaphragmatic hernia-7). Complications included short gut (2), sepsis (5), feeding difficulties (2), pneumonia (3), small bowel obstruction (2), and other (15). Nine patients (8.8%) died (trisomy 18-1, trisomy 13-1, intestinal necrosis-3, hepatic failure-1, prematurity-1, other sepsis-2). Two hundred sixteen children with intestinal malrotation have been treated from 1937 to 1987. Mortality rate has improved from 23% to 2.9%.

Primary neoplasms of the small bowel are unusual and constitute 1-5% of all gastrointestinal tract neoplasms. Preoperative diagnostic difficulties, frequent dissemination at the time of the diagnosis, and poor prognosis are characteristic of this pathology. During a period of 26 years we treated 61 patients with tumors of the small bowel, 44 malignant and 18 benign (1 patient had both). The most common symptoms were abdominal pain (62%), weight loss (41%), and gastro-intestinal bleeding (31%). More than half of the patients were treated as emergencies and among the remaining, the most useful diagnostic test was the small intestinal barium study. Seventeen patients were operated on for intestinal obstruction, 6 of them due to intussusception of the tumor, while 8 other patients presented with perforation and 7 with massive gastrointestinal bleeding. Leiomyoma was the most frequent benign lesion. Among malignancies lymphoma was encountered in 38.6%, followed by adenocarcinoma (29.6%) and leiomyosarcoma (22.8%). Lymphoma was predominant among Sephardic Jews. Curative procedures were attempted in all but one of the benign cases and in 21 of the malignant cases. At the time of surgery metastases were present in 23 patients. The postoperative mortality was high (20% and 14% in the benign and malignant groups, respectively) most probably due to the high incidence of emergency surgery in a high risk population. The prognosis of the malignant tumors was poor with a 5-year survival of 18%. Their disappointing course seems to be related to late diagnosis because of nonspecific symptoms and difficulty in bringing the tumor to the fore. Hopefully, a greater awareness will lead to an earlier diagnosis and improve the prognosis.

A 44-year-old man with acute jejunoileitis of unknown etiology developed small bowel obstruction. Intermittent abdominal pain, bloody diarrhea, ascites, and leukocytosis were prominent features. All stool cultures were negative. On steroid treatment, symptoms and radiographic features completely resolved. We suggest, in agreement with an earlier report, that acute jejunoileitis may be regarded as a distinct clinical entity.

Congenital and acquired diverticula of the jejunum and ileum in the adult are unusual and occur in approximately 1 percent to 2 percent of the population. They are pulsion diverticula thought to be the result of intestinal dyskinesia. These lesions can produce a significant diagnostic and therapeutic dilemma. They are multiple in the jejunum and solitary distally and are characteristically found in 60- or 70-year-old males. The diagnosis may be confirmed with contrast studies of the small intestine, arteriography, or nuclear scan. Consider these disorders in patients with 1) unexplained gastrointestinal bleeding, 2) unexplained intestinal obstruction, 3) an unexpected cause of acute abdomen, 4) chronic abdominal pain, 5) anemia, or 6) malabsorption. Medical therapy is helpful in controlling diarrhea and anemia, while surgical therapy is reserved for hemorrhage, obstruction, perforation, or failure of medical management. Asymptomatic diverticula discovered on routine contrast studies need not be resected. At surgery, incidental diverticula should be removed when evidence of dilated, hypertrophied loops of small bowel with large diverticula is found. Intraoperative air distention will aid in diagnosis. Resection and primary anastomosis is the preferred treatment for non-Meckelian diverticula. Diverticulectomy is reserved for a Meckel's diverticulum without evidence of ulceration. An incidental Meckel's diverticulum should be removed in the presence of mesodiverticular bands or ectopic tissue. Removal of a Meckel's diverticulum is not advised in the patient with Crohn's disease but may be performed in the patient undergoing restorative proctocolectomy for ulcerative colitis.

Primary peritoneal serous micropapillomatosis of low malignant potential, or serous borderline tumor of the peritoneum, is a relatively rare lesion that is histologically indistinguishable from peritoneal "implants" associated with ovarian papillary serous tumors of low malignant potential. We analyzed 17 cases to further define the pathologic features and prognosis of this entity. The ages of the patients ranged from 16 to 67 years (mean, 33 years). Eight patients were symptomatic with chronic pelvic or abdominal pain (five patients), adnexal mass (one patient), small-bowel obstruction (one patient), and possible endometriosis (one patient). In nine cases (53%), peritoneal serous micropapillomatosis of low malignant potential was an incidental finding discovered during evaluation or treatment of other conditions. Grossly, the peritoneal lesions were focal or diffuse. They commonly appeared as miliary granules and often were believed to be peritoneal carcinomatosis. Microscopically, peritoneal serous micropapillomatosis of low malignant potential had all of the patterns seen in superficial ("noninvasive") peritoneal implants of ovarian serous borderline tumors. Psammoma bodies were a prominent feature of all cases. Twelve patients also had typical endosalpingiosis. Most patients were treated by hysterectomy and bilateral salpingo-oophorectomy. Surgical treatment in seven patients consisted only of biopsy. Ten patients had residual unresected disease at the time of their initial operation. Several patients received adjuvant chemotherapy. Follow-up was available for 14 of the 17 patients. One patient died of metastatic breast carcinoma at 3.8 years; another patient died 7 weeks after operation, possibly as a complication of therapy. The other 12 patients were alive at last known contact after follow-up intervals of 8 months to 16.2 years (mean, 7.5 years). Two of these 12 patients developed multiple episodes of small-bowel obstruction due to persistent peritoneal serous micropapillomatosis of low malignant potential; neither received adjuvant chemo- or radiotherapy. Both were alive without progressive disease 10.9 and 16.2 years after initial diagnosis, respectively. This excellent prognosis supports a regimen of conservative therapy for these patients.

A case of warfarin-induced intramural hematoma and hemorrhagic infarction of the small intestine is described, and the literature on this adverse effect is reviewed. A 32-year-old white woman who had been receiving warfarin and carbamazepine came to a clinic complaining of lower back and stomach pain. She had a history of iliofemoral deep venous thromboses and seizures. A pelvic sonogram showed a large quantity of fluid present. Her prothrombin time (PT) was 29.2 sec. Her hemoglobin concentration and hematocrit were within the normal ranges. The patient was admitted to the hospital when her back pain increased and she vomited. The warfarin was discontinued. On day 5 the patient was still having abdominal pain and nausea. Her hemoglobin concentration and hematocrit had fallen to 6.6 g/dL and 20%, although her PT had decreased to 12.5 sec. On the same day, the patient underwent an exploratory laparotomy, and an indurated and ischemic area of jejunum was found and resected. The pathology report indicated the presence of hemorrhage and infarction consistent with an anticoagulant-related disorder. About 100 cases of intramural hematoma of the small intestine induced by anticoagulant therapy have been reported. Most patients are white males about 60 years of age. The sites most frequently involved are the duodenum and proximal jejunum. Symptoms include constipation, nausea, vomiting, and abdominal pain. Laboratory test and radiological findings are fairly nonspecific, but when found together in a patient receiving an anticoagulant, the diagnosis can be made with some confidence. Management may be complicated by the bleeding disorder, the intestinal obstruction if present, and the original indication for warfarin therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Gallbladder cancer afflicts predominantly women, the elderly, and persons with gallstones. Despite its producing symptoms of abdominal pain, nausea and vomiting, weight loss, jaundice, and anorexia, this disease remains difficult to detect. Even with contemporary imaging techniques, most gallbladder cancers escape diagnosis until the time of laparotomy. The aggressive character of this malignancy permits an overall 5-year survival rate of 3-5%. Although cures occur, the majority of operations performed for gallbladder cancer are for palliation. The objects of palliation include relief of pain, relief of jaundice, relief of intestinal obstruction, and the restoration of normal food intake. Resection of the tumor should be performed whenever possible; however, extensive operations including large liver resections and pancreaticoduodenectomy should be avoided in the presence of distant metastases. In the presence of large unresectable hilar masses, internal biliary bypass may relieve jaundice. Biliary-enteric anastomosis using the segment III duct exposed via the umbilical fissure may offer satisfactory relief of jaundice in selected cases.

Ischaemic colitis is a relatively rare but well-defined disease entity. It is associated with high mortality rate if early diagnosis and adequate surgical treatment is not accomplished. The aim of the present study was a clinical analysis of 7 patients with the verified ischaemic colitis. The delay from admission to the correct diagnosis was 8 days on the average (range 2-15 days). The reasons for delayed diagnosis included suspicion of diverticulitis, Crohn's disease and bowel obstruction as well as poor general condition in one case because of which early colonoscopy was not done. It is concluded that in patients with abdominal pain, rectal bleeding and diarrhoea associated with typical clinical findings, ischaemic colitis should be suspected. This suspicion should be followed by early colonoscopy to detect the gangrenous form of the disease as early as possible. Instant laparotomy and excision of the affected bowel is necessary for cure in these patients.
