Efficacy of Pancreatic Dissection With a Triple-row Stapler in Laparoscopic Distal Pancreatectomy: A Retrospective Observational Study.

Background: Postoperative pancreatic fistulas (POPFs) occur after 20% to 30% of laparoscopic distal pancreatectomies. This study aimed to evaluate the clinical efficacy of laparoscopic distal pancreatectomy using triple-row staplers in preventing POPFs.

Methods: Between April 2016 and May 2023, 59 patients underwent complete laparoscopic distal pancreatectomies. There were more females (n=34, 57.6%) than males (n=25, 42.4%). The median age of the patients was 68.9 years. The patients were divided into slow-compression (n=19) and no-compression (n=40) groups and examined for pancreatic leakage. Both groups were examined with respect to age, sex, body mass index (BMI), pancreatic thickness at the pancreatic dissection site, pancreatic texture, diagnosis, operative time, blood loss, presence of POPF, date of drain removal, and length of hospital stay. In addition, risk factors for POPF were examined in a multivariate analysis.

Results: Grade B POPFs were found in 9 patients (15.3%). Using univariate analysis, the operative time, blood loss, postoperative pancreatic fluid leakage, day of drain removal, and hospital stay were shorter in the no-compression group than in the slow-compression group. Using multivariate analysis, the absence of POPFs was significantly more frequent in the no-compression group (odds ratio, 5.69; 95% CI, 1.241-26.109; P =0.025). The no-compression pancreatic dissection method was a simple method for reducing POPF incidence.

Conclusions: The method of quickly dissecting the pancreas without compression yielded better results than the method of slowly dissecting the pancreas with slow compression. This quick dissection without compression was a simple and safe method that minimized postoperative pancreatic fluid leakage, shortened the operative time and length of hospital stay, and reduced medical costs. Therefore, this method might be a clinically successful option.
