Efficacy of Linear Stapler With Polyglycolic Acid Felt for Preventing Graft Duodenal Perforation After Pancreas Transplant.

OBJECTIVES

Graft duodenal perforation is a serious complication in pancreas transplantation. The aim of this study was to evaluate whether using a reinforced linear stapler during bench surgery in pancreas transplant affects the risk of graft duodenal perforation.

MATERIALS AND

METHODS

This retrospective study included 47 patients who underwent pancreas transplant at our institution from 2011 to 2020. A reinforced stapler with polyglycolic acid felt was used to dissect the graft duodenum during bench surgery in 16 of the 47 patients (reinforced group). A conventional linear stapler was used in the remaining 31 patients (conventional group). Demographic, perioperative, and postoperative parameters were compared between the reinforced group and the conventional group.

RESULTS

Graft duodenal perforation occurred in 6 patients (19.4%) in the conventional group and in none of the patients in the reinforced group. Logistic regression analysis revealed no significant associations between donor- orrecipient-related factors and graft duodenal perforation. Among operative factors, use of a reinforced stapler was the only factor significantly associated with the risk of graft duodenal perforation (odds ratio = 0.12).

CONCLUSIONS

The use of a reinforced stapler during dissection of the duodenum in bench surgery for pancreas transplant was associated with a lower risk of graft duodenal perforation than use of a conventional stapler.
