Impact of Decompression Tube Placement in Duodenal Graft on Graft Perforation After Pancreas Transplantation.

Background: Duodenal graft perforation (DGP) is a serious complication after pancreas transplantation (PTx) and can lead to pancreas graft loss. Here, we investigated whether the placement of a decompression tube (DT) for the duodenal graft during PTx is clinically useful for preventing DGP.
Methods: This study included 54 patients who received PTx for type 1 diabetes at our institution between 2000 and 2020. Among these cases, 28 included DT placement (51.9%; DT group), and the remaining 26 without DT placement (non-DT group) were used as historical controls for comparison to the cases with DT placement.
Results: Among all 54 cases, DGP occurred in 7 (13.0%). The DGP incidence did not significantly differ between the DT group (10.7%, 3/28 cases) and the non-DT group (15.4%, 4/26 cases) (P = .6994). Logistic regression analysis showed that DT placement did not affect DGP risk. Notably, 5 cases in the DT group (17.9%) exhibited adverse effects that were likely the result of DT placement, including bleeding from tube contact (2 cases), enterocutaneous fistula at the DT placement site (2 cases), and intraabdominal abscess around the DT site (1 case). Pancreas graft survival after PTx did not significantly differ between the DT and non-DT groups (P = .6260).
Conclusions: The DT group did not exhibit superior outcomes compared with the non-DT group. This result suggests that DT placement did not have a clinical impact on DGP prevention after PTx.
