A rare case of simultaneous obstructions of the proximal colon secondary to an obstructing carcinoma of the transverse colon and an ascending colon volvulus at the hepatic flexure is presented. Their probable interrelationship and resulting radiographic features are discussed.

Sigmoid volvulus in children is quite rare and may occur in acute fulminating form requiring early diagnosis and surgery. In this case, bowel continuity after resection of the necrotic sigmoid was reestablished in a two-stage operation.

Although it is clear that there is a significant frequency of recurrent volvulus after cecopexy, there is no evidence from either this series or previous reports that resection is associated with a lower recurrence rate than tube cecostomy. In the absence of data suggesting a clear superiority of colon resection, it appears that tube cecostomy should be the treatment of choice for cases of cecal volvulus that are not complicated by vascular compromise.

Three patients had recurrences of left-sided colonic volvulus after allegedly total resections of redundant sigmoid loops. All three patients had chronic, acquired megacolon. Other instances of late recurrence of volvulus after sigmoidectomy are documented in the literature. Sigmoidectomy may be an inadequate operation for sigmoid volvulus in younger patients and/or in patients with severe chronic megacolon. The decision to perform an interval operation and the selection of the type of operation must take this into account.

A case of pancreatitis that preceded and complicated, in the postoperative phase, one of ileal volvulus imprisoned in the Douglas and operated two days after admittance is reported. Clinical and laboratory data only permit hypotheses and this uncommon case of associated pathology is reported so that the situation can be borne in mind in the practical solution of surgical emergency.

A system developed in our laboratory for the in vitro cultivation of larval Onchocerca volvulus is being employed in a series of morphogenetic, physiologic, chemotherapeutic and immunologic investigations of this parasite. Because of the need for a large and readily available supply of living worms for this work, cryogenic techniques are being used for the long-term preservation of larval parasites collected in various endemic areas of Guatemala, C.A. To date, microfilariae have survived frozen storage in human cutaneous tissues (excised nodules and skin snips) for as long as 504 days, and viable larvae, in all stages of development have been recovered from the black fly vectors (Simulium ochraceum and S. metallicum) kept frozen for 396 days. That cryopreservation does not appear to affect these parasites adversely is indicated by the fact that microfilariae derived from frozen tissues do not differ from those obtained from fresh tissues on the basis of: 1) numbers and vigor of emergent microfilariae; 2) survival and morphogenesis of microfilariae during cultivation in vitro for 24 days; 3) glucose utilization during 72 hours of incubation; and 4) their incorporation of 3H-amino acids as determined after 18 hours of incubation. Details of methodology for cryopreservation and in vitro cultivation, together with resultant data, are presented herein.

During the last 30 years the author has been performing comprehensive clinical observations of numerous patients with megadolichosigmoids. Among them 180 patients were operated for extreme pathological forms of megadolichosigmoids without a single lethal outcome. The analysis of remote results of the treatment of 173 patients is presented. The period of observation was from 3 to 25 years. The author believes that the operative method of choice in megadolichosigmoids is a one-step subtotal mesosigmoresection. It saves the patients from chronic ileus and is a reliable prophylaxis of acute volvulus of the sigmoid.

Pneumatosis coli is an uncommon disease which is frequently misdiagnosed and inappropriately treated. The condition can usually be managed conservatively but complications requiring surgical treatment are occasionally encountered. We describe 4 patients with pneumatosis coli and associated volvulus of the sigmoid colon. Some of the factors that may have contributed to pneumocyst formation in these 4 patients are discussed with reference to recent advances in our understanding of the pathogenesis of pneumatosis coli.

Volvulus of the jejunum and ileum in three horses was associated with intestinal strangulation in a mesenteric rent. The rent was in the jejunal mesentery at its point of attachment with an anomaly that was classified as a mesodiverticular band. The band also was attached to the dorsolateral surface of the jejunum, thus forming one side of a triangular hernial sac that was completed on the other side by the adjacent jejunal mesentery. Incarceration of a loop of small intestine in the hernial sac preceded rupture of the jejunal mesentery and subsequent intestinal strangulation. Surgical correction was successful in two horses and involved resection of the gangrenous intestine, then jejunocecal anastomosis. The third horse was euthanatized when intestinal rupture and peritonitis were found on exploratory laparotomy. Two mesodiverticular bands attached to the distal jejunum were incidental necropsy findings in a fourth horse.

Experimental closed loop small intestinal volvulus was studied in the anesthetized horse. Volvulus was simulated by ligation of the mesenterial veins to a segment of small intestine. Physical signs and hemodynamic, hematologic, clinical chemical, bacteriologic and peritoneal fluid values were examined. Compared to conscious horses anesthesia highly delayed and modified the clinical signs of shock (changes in mucosal colour, dehydration, decreased skin temperature, elevated pulse rate, low blood pressures) and of small intestinal volvulus (altered peristalsis, gastric dilation). Plasma glucose response to shock was also modified by unconsciousness. However, a dose response relationship was indicated between the extent of small intestinal damage and clinical symptoms. The same was applicable to changes in blood pressures, blood acid-base balance, lactate, potassium, chloride, glucose, inorganic phosphorus, creatinine, creatine kinase, red blood cell and total white blood cell counts and serum total protein. The relationship was also indicated in the following peritoneal fluid values: volume, lactate, pH, total white cell counts, alkaline phosphatase and bacteriology. Changes related to shock (insufficient tissue perfusion) were low blood pressures and metabolic acidosis due to anaerobic glycolysis with accumulation of lactic acid. Also low plasma glucose and elevated plasma potassium, creatinine, inorganic phosphorus and creatine kinase were regarded as consequences of shock.
