Several hemodynamic abnormalities in the patient with cirrhosis comprise a unique distributive circulatory disturbance that causes intractable ascites and that is, in turn, worsened by the resulting ascites. Ascites is promptly alleviated by drainage of the ascitic fluid into the intravascular compartment. The circulatory abnormalities improve in part because of elimination of the ascites, and also because of a compensatory hypervolemia. The consequences of the latter, especially in the immediate postoperative period, are increased likelihood of pulmonary edema and of gastrointestinal bleeding from heightened portal vein pressure. Postoperative coagulopathy is also a significant problem. Careful selection of patients for the procedure, close postoperative observation and vigorous use of diuretics and other agents will usually enable these complications to be obviated or successfully treated. Increases in body muscle and fat masses and serum albumin concentrations indicate nutritional improvement. Despite evidence of benefits from the procedure, these patients continue to die from the complications that threaten other cirrhotics: effects of return to alcoholism, gastrointestinal hemorrhage, recurrent infections and intestinal obstruction. Thus, it is not yet clear that the benefits include prolongation of life.

Three cases of premature infants with obstruction of the ileum and proximal colon in the absence of cystic fibrosis are presented. Meconium inspissation complicated low-grade bowel obstruction in 2 infants. In the third, the bowel was anatomically normal, with the tenacious meconium the apparent primary cause of obstruction. Distinguishing features of this unusual type of blockage and other meconium syndromes are also discussed. This condition may simulate necrotizing enterocolitis, requiring surgery for differentiation. It should be considered in the differential diagnosis of low small bowel or colonic obstruction in the premature infant who is several days of age.

Small bowel leiomyosarcomas are uncommon but potentially curable tumors often diagnosed at an advanced stage. Twenty such lesions were studied, and 19 of these produced symptoms and signs. Clinical findings included abdominal pain in 17 (85%), rectal bleeding in 8 (40%), anemia in 7 (35%), intraperitoneal perforation in 6 (30%), and abdominal mass in 4 (20%). Various abdominal x-ray examinations revealed nonspecific abnormalities (ileus, bowel obstruction, abdominal mass) in about half the cases in which they were obtained, but in only one instance was the correct diagnosis of small bowel tumor made preoperatively. Five of 12 patients undergoing resection in hope of cure survived five years. These tumors tend to metastasize by hematogenous dissemination, peritoneal implantation, local invasion, and, uncommonly, lymphogenous spread. Wide small bowel resection with adjacent mesentery is suggested for most lesions. Five year survival following resection approximates 50% in reported series.

Between 1964 and 1978 8748 operations had been performed because of benign diseases of the extrahepatic biliary tract, 413 cases of mechanical intestinal obstruction had been operated, out of these 30 patients with gallstone ileus. The frequency, pathogenesis, symptomatology, diagnostic procedure and therapy are described, the own results are discussed.

A case of leiomyoma of the duodenum presenting with sub-acute intestinal obstruction and a palpable abdominal mass is described. Both the siting of the lesion in the duodenum and a presentation other than gastro-intestinal bleeding are unusual for this type of tumour.

From 1970 through 1977, 92 patients with ovarian cancer received 20 Gy (2,000 rad) to the abdomen, followed by 30 Gy (3,000 rad) to the pelvis. Small-bowel obstruction developed in 7 (7.6%). The number of previous laparotomies, thin physique, and hypertension were significantly associated with complications. Two patients receiving isoniazid and 2 receiving Premarin had enteric complications. Pre-existing vascular damage may potentiate radiation damage to the small bowel.

Two cases of solitary small intestinal lipoma are presented. One occured in the duodenum as a submucosal pedunculated polyp with a bleeding ulcerated surface. This was diagnosed by means of the fiberoptic duodenoscope (Olympus D1G2). The second involved a large massive submucosal lipoma which formed the leading edge of an intussusception resulting in small bowel obstruction. A brief review of the pathology, complications, symptoms, radiographic diagnosis and treatment of small intestinal lipomas is given.

Two cases of neonatal intestinal obstruction, with clinical, radiological and evolutive characteristics typical of the "neonatal small left colon syndrome", are described. Some etiological aspects are commented upon as well as differential diagnosis, which must be done with a certain number of diseases that produce intestinal obstruction in the newborn. Authors consider of great interest the high incidence of this syndrome in children born to diabetic mothers, diagnostic value of barium enema and the usually benign clinical course with very simple therapeutic procedures.

Two patients with intestinal obstruction in pregnancy are presented and discussed. In neither case was there any obvious cause for the intestianl obstruction. Pseudo-obstruction of the bowel has not previously been described as a complication of pregnancy.

A case of generalized amyloidosis associated with cyclic neutropenia is presented. A 24-yr-old female with cyclic neutropenia died from intestinal obstruction caused by necrosis and perforation of the small intestine. Post-mortem examination revealed generalized amyloidosis involving almost all organs. Amyloid deposits were prominent, especially in the alimentary tract, kidneys, spleen, and small blood vessels. As has been suggested in gray collie dogs with congenital cyclic neutropenia known to develop secondary amyloidosis in adulthood, an increase of antigenic stimulation during the intermittent bouts of acute infections may be one of the factors responsible for the development of secondary amyloidosis in this case. Although the association of amyloidosis and cyclic neutropenia in man has rarely been described, it is probable that amyloidosis is not a rare complication of human cyclic neutropenia, considering that patients with this hematologic disorder are chronically exposed to excessive antigenic stimulation.
