Unusual sites of upper gastrointestinal variceal bleeding.

When patients with portal hypertension bleed from varices, these are most commonly located in the esophagus and gastric fundus. However, varices can develop anywhere in the upper or lower gastrointestinal tract. Oftentimes if an active upper gastrointestinal bleeding site is not evident at the time of endoscopy, bleeding is attributed to any esophageal or gastric varices that are present. This supposition may not always be true as illustrated in the two patients presented here. Likewise, the absence of esophagogastric varices in a patient with portal hypertension does not preclude the presence of varices elsewhere. Endoscopic examination of the second and third portion of the duodenum can sometimes be helpful in accurately locating the bleeding site.

Postoperative nutritional support using needle catheter feeding jejunostomy.

Needle catheter jejunostomy was used as an adjunctive surgical procedure in 110 patients. In 19 patients (or 17%) the jejunostomy was of value for the administration of post-operative nutritional support using an elemental diet and it may serve as an alternative route for the administration of supplementing fluids and electrolytes if intestinal function is intact. The clinical experience with the catheter jejunostomy establishes it as a satisfactory technique for postoperative nutritional support in patients requiring esophageal and proximal gastric resection and repair, and gastric surgery in the elderly and debilitated. It is also useful in patients undergoing complicated biliary, pancreatic, and duodenal surgery in whom anastomotic difficulties are anticipated.

Colorectal schistosomiasis: report of three cases.

The facility for mass movement of segments of our world populations creates the need for physicians to recognize and manage diseases not seen in native patients. Such a need has occurred in New York City, where schistosomiasis, with its protean manifestations has been seen with increasing frequency. The cases of three patients who had different clinical manifestations of infestation by S. mansoni are presented. Clinical, radiologic, and pathologic features are discussed. To avoid delay in treatment, physicians must consider the possibility of this disorder in cases of patients from areas of endemic schistosomiasis.

The use of enzyme analysis of peritoneal blood in the clinical assessment of abdominal organ injury.

Seventy patients with blunt and penetrating abdominal trauma and hemoperitoneum were evaluated by the analysis of the enzyme content of peritoneal blood using automated laboratory methods. The enzyme levels in peritoneal blood were evaluated relative to the simultaneous levels in peripheral blood to identify enzyme differences in organ-related peritoneal and periheral blood. The findings in this study indicate that isolated liver injuries are associated with significant elevation of lactic dehydrogenase levels in peritoneal blood and glutamic-oxalacetic transaminase levels in peritoneal and peripheral blood. A multiplicity of abdominal organ injury results in elevation of lactic dehydrogenase and glutamic-oxalacetic transaminase levels in peritoneal blood. The occurrence of isolated small intestinal injury and small intestinal injury combined with other organ injury produces a significant elevation of glutamic-oxalacetic transaminase, lactic dehydrogenase and alkaline phosphatase levels in peritoneal blood. The alkaline phosphatase elevation in peritoneal blood is associated with normal mean values in peripheral blood; therefore, combined alkaline phosphatase in peritoneal and peripheral blood has potential for use in the identification of small intestinal injury in patients with hemoperitoneum of traumatic origin.

Spontaneous rupture of the rectosigmoid colon with anal evisceration: a new complication of uterine prolapse.

Spontaneous large bowel perforations have been associated with chronic constipation. The previously reported episodes of anal evisceration of small intestine have occurred in patients with a rectal prolapse. An end-stage complication of chronic third degree uterine prolapse is presented. A laceration of the anterior rectosignoid colon wall permitted small bowel extrusion through the anus. The tearing effect exerted by the prolapsed uterus at the rectouterine fold presumably caused the rectosigmoid laceration.

Intravenous rupture of arteriosclerotic aneurysms of the abdominal aorta.

Intravenous rupture of abdominal aortic aneurysms occurs infrequently but should be considered with the coexistence of severe congestive failure, anasarca, and abdominal bruits. Six patients are presented with four survivors. In only two patients was the diagnosis considered preoperatively without angiography. Two were variants in that thrombus occluded the fistula, thereby negating findings usually manifested clinically. Diagnosis of this type can be made only during operation when copious venous bleeding ensues with evacuation of the aortic thrombus. Careful fluid management and prompt surgery are prerequisites to obtaining a successful outcome. Repair is accomplished easily by suturing the fistula from the aortic aspect, but care is required to avoid dislodgement of thrombus and atherosclerotic debris resulting in pulmonary embolism.
