OBJECTIVE: This study aimed to examine the factors linked to the development of clinically significant pancreatic fistulas following distal pancreatectomy (DP) and to assess the efficacy of suture ligation of the main pancreatic duct.

PATIENTS AND METHODS: A single-center retrospective study was performed on the medical records of 82 patients who underwent DP in our institution between January 2011 and December 2019.

RESULTS: There were 28 males (34.1%) and 54 females (65.9%). The patients’ age ranged from 18 to 86 years (median: 55.5 years). Indications for DP included primary pancreatic disease (n=63, 76.8%) and non-pancreatic disease (n=19, 23.2%). Postoperative mortality and morbidity rates were 3.7% and 48%, respectively. Pancreatic parenchymal closure was accomplished by a hand-sewn technique or mechanical stapling in 89 and 13 patients, respectively. Identification of the pancreatic duct and suture ligation was performed in 46 patients (56.1%). Pancreatic fistula was developed in 20 patients (24.4%); 12 fistulas were classified as Grade B, and 8 as Grade C. Biochemical leaks (Grade A) were identified in 8 patients (9.8%). Multivariate analysis indicated that failure to ligate the main pancreatic duct was the only variable associated with an increased risk for pancreatic leak (p=0.031; odds ratio=0.233; 95% confidence interval, 0.062-0.879).

CONCLUSIONS: Pancreatic leak remains a common complication after DP. The incidence of leaks is reduced significantly when the main pancreatic duct is identified and directly ligated during DP.
