Background:
Pancreatic necrosectomy with concomitant internal drainage is a single-stage treatment option for walled-off pancreatic necrosis (WOPN). However, an optimal minimally invasive technique has not been established. We evaluated the safety and single-intervention success rate of robotic pancreatic necrosectomy and internal drainage.
Methods:
Patients with WOPN undergoing robotic pancreatic necrosectomy and internal drainage at a single institution from 2011-2022 were identified. The primary outcome was the rate of clinical symptom resolution following the index surgical intervention.
Results:
57 patients underwent robotic pancreatic necrosectomy and internal drainage, consisting of robotic cystgastrostomy (RCG, n = 37), robotic cystjejunostomy (RCJ, n = 13) and robotic fistulojejunostomy (RFJ, n = 7). Surgery was performed a median of 102 (range 28-1153) days following the onset of necrotizing pancreatitis. The median operative time was 187 (91-344) minutes and there were 2 (3.5%) conversions. The median length of hospital stay was 4 (2-38) days. Postoperative morbidity was 11%, and there was one (1.8%) 90-day mortality. At a median follow-up of 5.5 months, 53 (93%) patients had clinical symptom resolution after their index procedure and did not require any reintervention.
Conclusion:
In select patients, robotic pancreatic necrosectomy and internal drainage is safe and achieves a high single-intervention success rate.
