Subtotal gastrectomy in infancy for perforating necrotizing gastritis.

Necrotizing gastritis is a rare pathology causing a high rate of morbidity and mortality in the infants. A 4-week-old baby, with right hypoplastic kidney and ectopic ureter, was admitted because of profound septic shock and "coffee ground" vomitus. Aggressive treatment was started and hemodynamic stabilization was achieved. On the fourth admission day, ascites was noted and on the eighth day in a plain abdominal x-ray, free air was shown. At urgent explorative laparotomy, double posterior gastric wall perforations with extensive gastric wall necrosis were found, which required subtotal gastrectomy. The etiology and pathophysiology of this rare process are discussed with an emphasis on the difficulty in diagnosis of posterior gastric perforation into the lesser sac.

Acute cholecystitis complicating unrelated disease: etiological considerations.

The phenomenon of acute cholecystitis complicating an unrelated operation has been reported with increasing frequency, and may be preceded by a variety of operative procedures and a lack of previous biliary tract symptoms. Among eight such patients treated by us, seven developed acute cholecystitis postoperatively, and in one it was discovered during operation for bleeding duodenal ulcer. Two patients had undergone wide excision of the breast; two, highly selective vagotomy; one, nephrolithotomy; one, truncal vagotomy and gastroenterostomy; and one, left hemicolectomy and colostomy. In three patients, urgent cholecystectomy was performed, and four were treated conservatively with subsequent elective cholecystectomy. Histopathological studies revealed acute and chronic cholecystitis in all eight patients and cholelithiasis in four. One patient died in septic shock. Numerous contributing factors have been suggested, including hypovolemia and biliary stasis, as well as the presence of stones. It would appear that chronic cholecystitis or other biliary pathology, as found in our eight patients, is a major factor in the development of this manifestation.

Importance of small bowel involvement in bleeding angiodysplasia.

Lower intestinal bleeding related to enterocolic angiodysplasia is now accepted as a common clinical situation in the elderly. A planned approach is mandatory to allow early localization and appropriate therapy. Colonoscopy, scintigraphy and angiography used judiciously have almost entirely replaced exploratory laparotomy as a diagnostic tool. Nonoperative treatment comprising arteriographic selective vasopressin infusion and endoscopic coagulation has been followed in some cases by hemorrhage control. Such techniques, if easily obtainable, have their place; however, surgery remains the ultimate method for definitive treatment. A previous knowledge of the nature of ileal involvement is essential if surgical hemostasis is to be achieved. The recent successful management of three patients exemplifies the problems found in dealing with iliocecal bleeding angiodysplasia.

Assessment of splenic function in dogs following arterial ligation and autotransplantation.

Two methods for the preservation of splenic function following trauma to the spleen were studied and compared in dogs and puppies. One method was splenectomy and autotransplantation of small pieces of splenic tissue, and the other--ligation of the main branches of the splenic artery after partial splenectomy. Dogs subjected to splenectomy alone or laparotomy alone served as controls. Splenic function was assessed on the basis of resistance to sepsis by virulent pneumococci. Cultures were obtained from the blood, peritoneal fluid and intraabdominal organs 3 days after i.v. injection of the pneumococci; none of the adult dogs in any of the groups had positive cultures. Among splenectomized puppies, 55.5% had positive cultures for pneumococci, whereas those which underwent ligation of the splenic artery and partial splenectomy had negative cultures. Microscopic examination of the autotransplants revealed loss of the characteristic structure of splenic tissue, whereas in the dogs in which the splenic artery had been ligated, the spleen showed numerous islands of tissue with well-preserved follicular structure. We suggest that in children with severe splenic trauma, ligation of the splenic artery may provide a promising alternative to splenectomy.

Seminoma of intra-abdominal testis in sixty-seven-year-old man.

A sixty-seven-year-old man found to have a seminoma of an undescended intra-abdominal testis is believed to be the oldest reported patient with this presentation. This case emphasizes the importance of careful palpation of the testis as part of the routine physical examination at any age. Testicular tumor or metastases should be included in the differential diagnosis of retroperitoneal mass.
