Primary small bowel volvulus: cause and management

J. H. Duke Jr and M. S. Yar

Most reports of patients with primary small bowel volvulus have indicated that the ingestion of a high-bulk vegetable diet in some way contributes to the development of this condition. During a recent 13-month period at Nangarhar University Hospital at Jalalabad, Afghanistan, the frequency of occurrence among 26 patients was found to be related to abrupt changes in dietary intake. The first and last months of the study were Ramadan, the annual period in which Mohammedans abstain from all oral intake during daylight hours and take a single large meal after dark. During these two isolated months, there was a ten fold and nine fold increase, respectively, in the incidence of the condition. Early diagnosis and surgical intervention offer the only possibility for minimizing an otherwise excessive mortality.
