An analysis of the effectiveness of stapler closure combined with a titanium clip in distal pancreatectomy.

Purposes: Postoperative pancreatic fistula is the most common and severe postoperative complication of distal pancreatectomy. Treatment of pancreatic stump to reduce the incidence of postoperative pancreatic fistula is crucial. This study evaluated the effectiveness of stapler closure combined with a titanium clip in distal pancreatectomy.

Methods: Prospectively collected data of consecutive patients who underwent distal pancreatectomy from April 2013 to May 2020 with pancreatic transection performed by the bare stapler method (131 patients), stapler + hand-sewn closure method (199 patients), and stapler + titanium clip method (209 patients) were reviewed retrospectively and compared between groups.

Results: No statistically significant differences were observed in basic data among the three groups. There were also no significant differences among the three groups in terms of the intraoperative data or tumor pathological types, except for the number of laparoscopic treatment cases (23, 53, and 80 for bare stapler method, stapler + hand-sewn closure method, and stapler + titanium clip method, respectively; P < 0.05) and pancreatic neuroendocrine tumor cases (15, 29, and 12, respectively; P < 0.05). There were no significant differences in postoperative complications or parameters, except for the number of clinical pancreatic fistula cases (31, 27, and 13 for bare stapler method, stapler + hand-sewn closure method, and stapler + titanium clip method, respectively; P < 0.05) and postoperative length of hospital stay (11.6 ± 8.3, 10.6 ± 9.7, and 9.3 ± 6.9 days, respectively; P < 0.05). The stapler + titanium clip group had a significantly lower number of clinical pancreatic fistula cases and shorter postoperative length of hospital stay than the other groups. The univariate analysis showed that pancreatic resection line thickness was an independent risk factor for clinical pancreatic fistula after operation.

Conclusion: Stapler closure combined with titanium clips to reinforce the pancreatic stump is simple and easy to implement, effectively reduces the incidence of clinical pancreatic fistula, and shortens the postoperative length of hospital stay.
