Résumé
Laparoscopic distal pancreatectomy (LDP) is a challenging operation due to technical complexity and tumor-related factors. Aim of this study was to identify preoperative risk factors affecting LDP difficulty. Consecutive patients who underwent LDP between 2015 and 2018 at San Raffaele Hospital and Policlinico S.Orsola-Malpighi Hospital were enrolled retrospectively. Three variables were used to define surgical difficulty: conversion to open, duration of surgery >3rd quartile and intraoperative blood loss >3rd quartile. The presence of ≥1 of these 3 variables was considered as another measure of difficulty. Overall, 191 patients were included. Conversion to open was required in 25 patients (13%). At multiple regression analysis, tumor proximity to major vessels was the only independent predictor of conversion from laparoscopic to open (p < 0.001). No variables independently predicted an excessive duration of surgery. Male gender (p = 0.033) and increasing parenchymal thickness at resection line (p = 0.018) were independent predictors of excessive blood loss. Increasing parenchymal thickness at resection line (p = 0.014) and tumor proximity to major vessels (p = 0.002) were significant risk factors for the presence of ≥1 outcome of surgical difficulty. Male gender, increasing parenchymal thickness at resection line and tumor proximity to major vessels represent preoperative risk factors of LDP difficulty.

BACKGROUND
Laparoscopic distal pancreatectomy (LDP) is a challenging operation due to technical complexity and tumor-related factors. Aim of this study was to identify preoperative risk factors affecting LDP difficulty.
METHODS
Consecutive patients who underwent LDP between 2015 and 2018 at San Raffaele Hospital and Policlinico S.Orsola-Malpighi Hospital were enrolled retrospectively. Three variables were used to define surgical difficulty: conversion to open, duration of surgery >3rd quartile and intraoperative blood loss >3rd quartile. The presence of ≥1 of these 3 variables was considered as another measure of difficulty.
RESULTS
Overall, 191 patients were included. Conversion to open was required in 25 patients (13%). At multiple regression analysis, tumor proximity to major vessels was the only independent predictor of conversion from laparoscopic to open (p < 0.001). No variables independently predicted an excessive duration of surgery. Male gender (p = 0.033) and increasing parenchymal thickness at resection line (p = 0.018) were independent predictors of excessive blood loss. Increasing parenchymal thickness at resection line (p = 0.014) and tumor proximity to major vessels (p = 0.002) were significant risk factors for the presence of ≥1 outcome of surgical difficulty.
CONCLUSION
Male gender, increasing parenchymal thickness at resection line and tumor proximity to major vessels represent preoperative risk factors of LDP difficulty.
