Background:We describe an afferent loop obstruction caused by an adhesion band in a case of distal gastrectomy with Roux-en-Y end-to-side jejunal anastomosis for cancer.Methods:An initial clinical presentation of acute pancreatitis was ruled out by a computed tomography scan, which revealed intestinal obstruction; it was then confirmed on laparoscopy. Definitive treatment was laparoscopic adhesiolysis. A complete review of the literature concerning afferent loop obstructions is presented.Results:The treatment was successful, with minimal postoperative pain, and the 5-day hospital stay was uncomplicated. The patient remains asymptomatic at 1-year follow-up.Conclusions:The authors advocate minimally invasive surgery as a complete diagnostic and therapeutic alternative to emergency laparotomy in cases where afferent loop syndrome is suspected, and acknowledge that prompt surgery has a higher rate of success and reduces operative morbidity and mortality.

SUMMARY The effect of octapressin (2-phenylalanine-8-lysine vasopressin) on renal and intrarenal blood flow was studied in 11 normotensive cirrhotic patients with abnormal renal perfusion. Renal haemodynamic changes were assessed with the '33Xenon washout technique. Of the six patients given suppressor doses of octapressin intravenously renal blood flow improved in one only. A further three patients responded to the drug in a dose which increased the mean arterial pressure by 5 Ol more mm Hg. The increase in mean renal blood flow was accompanied by an improvement in renal cortical perfusion. In two patients renal blood flow decreased after the administration of octapressin. These findings, in conjunction with previous reports, suggest that octapressin will only consistently improve renal perfusion in cirrhotic subjects who are hypotensive and in whom the mean arterial blood pressure is raised by the drug, but do not exclude the possibility that octapressin may have a direct renal circulatory effect in some patients.
