Context Pancreaticoduodenectomy in partially-gastrectomized patients presents some peculiarities of the reconstructive phase. Above all, in B II and Roux-en-Y partial gastrectomies, a gastric re-resection with a redo gastrojejunal anastomosis should be avoided because it is often needlessly time-consuming and risky. In our series of 7 consecutive patients, either one of two reconstruction methods was used, depending upon the length of the pre-existing afferent loop. Case reports In order to better illustrate this strategy, two cases of carcinoma of the duodenal papilla are reported. Both of the patients had previously undergone partial gastrectomy with B II reconstruction for peptic ulcers. Both were admitted to our hospital with a past history of jaundice. However, whereas in Case #2 a sufficiently long pre-existent afferent loop could be utilized for the pancreatic and bile duct anastomoses, in Case #1 a shorter afferent loop was removed and the efferent loop was utilized for the anastomoses. The postoperative course was uneventful in both patients. Conclusions This reconstructive strategy for pancreaticoduodenectomy in gastrectomized patients, which uses either of the methods described above, has produced good results in our series of 7 patients and appears to be rational and straightforward.
