Background: Since its introduction, pancreaticoduodenal resection for periampullary cancer has undergone numerous modifications. As a result, there has been a dramatic decline in the mortality rate. However, a high morbidity rate, mainly due to pancreatic fistula formation, is still reported.
Objective: To evaluate the results of the use of a defunctionalized jejunal loop in patients undergoing pancreatoduodenectomy to minimize both the frequency and severity of anastomotic leak.
Setting: Second Surgical Department, Athens University, Aretaieon Hospital, Athens, Greece.
Design: A series of retrospective cases from February 1990 to December 1997.
Patients: One hundred five patients who underwent pancreatoduodenectomy and had the pancreatic stump drained in a defunctionalized jejunal loop.
Methods: To avoid problems related to fistula formation due to erosion of the anastomoses from activated pancreatic enzymes, a defunctionalized jejunal loop was constructed and the pancreatic stump was invaginated into the end of this loop.
Results: Using the defunctionalized jejunal loop, the mean (+/-SD) hospitalization was 7.57+/-1.42 days, the morbidity rate was 11.2%, and the mortality rate was 0.95%.
Conclusions: A modification of pancreatoduodenectomy for the treatment of pancreatic cancer resulted in an improvement in the immediate results of subtotal pancreatoduodenectomy. Careful detachment of the posterior surface of the pancreas from the anterior surface of the portal vein and performance of pancreaticojejunal anastomosis to a defunctionalized jejunal loop results in lower mortality and morbidity rates, thus making pancreatoduodenectomy a safe procedure.

Concomitant presentation of jejunal atresia and Hirschsprung's disease is rare and places children at high risk for developing short bowel syndrome and parenteral nutrition dependence, which can affect the feasibility/timing of pull-through. A patient was born with jejunal atresia with a delayed diagnosis of Hirschsprung's disease. After several procedures and bowel resections, the patient was ultimately left with an end jejunostomy and long Hartman's pouch with short bowel syndrome, dependent on parenteral nutrition.

Sleeve gastrectomy with jejunal bypass (SGJB) has been used as a bariatric/metabolic procedure since 2003, in the search for a simpler than other standard techniques and as effective as them. The jejunal-ileal anastomosis can deliver food directly to the hindgut where incretins are secreted. This procedure has gained popularity around the globe and has been studied in rat models as in humans, especially in South America and Asia.

Background: Bariatric surgery produces anatomic changes in the digestive tract that can affect the intestinal microbiome and, in some cases, can cause small intestinal bacterial overgrowth. Since the inception of the sleeve gastrectomy with jejunal bypass (SGJB) in 2004, there has been discussion regarding the possible development of those complications associated with the now abandoned jejunoileal bypass (JIB) procedure.
Objectives: The primary endpoint was to characterize the bacteriologic and histopathologic findings in the defunctionalized jejunal loop after the SGJB procedure and to analyze the liver profile.

Background/purpose: Intraluminal springs have recently been shown to lengthen segments of intestine in a process known as distraction enterogenesis. We hypothesized that biocompatible springs could be used to lengthen defunctionalized murine small intestine and would lead to identifiable intestinal adaptations at the molecular level.
Methods: Age and weight matched C57BL/6 mice underwent surgical insertion of nitinol spring-loaded capsules into a Roux limb of jejunum.
