Outcomes in Endoscopic and Operative Transgastric Pancreatic Debridement

Abstract

Objectives: Select patients with anatomically favorable walled off pancreatic necrosis may be treated by endoscopic (Endo-TGD) or operative (OR-TGD) transgastric debridement (TGD). We compared our experience with these 2 approaches. Summary background data: Select necrotizing pancreatitis (NP) patients are suitable for TGD which may be accomplished endoscopically or surgically. Limited experience exists contrasting these techniques exists. Methods: Patients undergoing Endo-TGD and OR-TGD at a single, high-volume pancreatic center between 2008 and 2019 were identified from a prospective database. Patient characteristics, procedural details, and outcomes of these 2 groups were compared. Results: Among 498 NP patients undergoing necrosis intervention, 160 (32%) had TGD: 59 Endo-TGD and 101 OR-TGD. The groups were statistically similar in age, comorbidity, pancreatitis etiology, necrosis anatomy, pancreatitis severity, and timing of TGD from pancreatitis insult. OR-TGD required 1.1 ± 0.5 and Endo-TGD 3.0 ± 2.0 debridements/patient. Fewer hospital readmissions and repeat necrosis interventions, and shorter total inpatient length of stay were observed in OR-TGD patients. New-onset organ failure [Endo-TGD (13%); OR-TGD (13%); P = 1.0] was similar between groups. Hospital length of stay after TGD was significantly longer in patients undergoing Endo-TGD (13.8 ± 20.8 days) compared to OR-TGD (9.4 ± 6.1 days; P = 0.047). Mortality was 7% in Endo-TGD and 1% in OR-TGD (P = 0.04). Conclusions: Operative and endoscopic transgastric debridement achieve necrosis resolution with different temporal and procedural profiles. Clear multidisciplinary communication is essential to determine appropriate approach to individual necrotizing pancreatitis patients.
