Abstract
Introduction
Internal drainage of walled of necrosis of pancreas has been considered as the standard of care. For symptomatic walled off necrosis (WON) of pancreas with the advent of laparoscopy and refinement of techniques and instrumentation, laparoscopic internal drainage is becoming the standard surgical drainage procedure for these patients. However, there is a dearth of literature regarding outcomes following laparoscopic drainage. Most of the studies have small number of patients with limited follow-up. We in this study describe our experience of laparoscopic internal drainage of walled off necrosis over the last 13 years.
Materials and methods
This is a retrospective analysis of a prospectively maintained database. All patients with WON undergoing laparoscopic internal drainage between January 2005 and December 2018 were included. Primary outcome measure was successful drainage. Secondary outcome measures included morbidity, hospital stay, re-intervention rate and mortality. Patients were followed up post-operatively at 1 week, 4 weeks, 3 months and then annually thereafter. Ultrasonography was done periodically for the assessment of cyst resolution.
Results
Between 2005 and 2018, 154 surgical drainage procedures were performed for symptomatic pseudocyst/walled off necrosis. Out of these, 134 underwent laparoscopic drainage; 129 patients (96.3%) underwent laparoscopic cystogastrostomy and 5 (3.7%) underwent laparoscopic cystojejunostomy. Majority of the patients were male (male:female = 6:1) with a mean age of 36 ± 12.9 years (range 15–58 years). The mean operative time was 94 min (range 64–144 min). There were three conversions because of intra-operative bleeding. The overall post-operative morbidity was 8.9%. The average hospital stay was 4.4 days (2–19 days). The mean duration of follow-up was 5.5 years (range 6 months–13 years). Complete cyst resolution was achieved in 95.5% (n = 128) patients. There has been no mortality till date.
Conclusion
In conclusion, laparoscopic internal drainage is a very effective technique for drainage of WON with an excellent success rate.
