Laparoscopic-Assisted Pancreatic Necrosectomy: Technique and Initial Outcomes.

DEBRIDEMENT; NECROTIZING pancreatitis; LOGISTIC regression analysis; HOSPITAL mortality

Background: Necrotizing pancreatitis (NP) may result de novo or following procedures such as ERCP or partial pancreatectomy (post-procedural), and may require surgical debridement. Video-assisted retroperitoneal debridement (VARD) is a standard approach for NP that employs a 5 cm incision with varying degrees of blind and open debridement. We describe our technique and outcomes of a modified VARD called laparoscopic-assisted pancreatic necrosectomy (LAPN) performed through a single 12 mm incision that uses direct laparoscopic visualization during debridement. Methods: At one medical center, all LAPN patients (2012-2020) were assessed for demographics, disease factors, and outcomes. Bivariate logistic regression analyses were performed to identify factors independently associated with recovery after LAPN for patients with de novo vs post-procedural necrosum. Results: Over 9 years, 60 patients underwent LAPN for NP. Median age was 57 years (IQR: 47-66) and 43 (69%) were men. Pancreas necrosum was de novo in 39 (63%) patients and post-procedural in 23 (37%). NP resolved with a median of 1 LAPN procedure and median hospitalization was 33 days. The LAPN major morbidity rate and in-hospital mortality rate were 47% and 5%. No significant differences were seen between NP etiology cohorts, although post-procedure NP patients trended towards a faster clinical recovery to baseline compared to de novo patients (193 vs 394 days; p -value =.07). Conclusions: LAPN offers a smaller incision with excellent visualization and non-inferior outcomes, regardless of etiology, with likely faster recovery for patients with post-procedural vs de novo necrotizing pancreatitis.
