Prospective comparison of long term outcomes in patients with severe acute pancreatitis managed by operative and non operative measures

Aim: Present study reports the long term functional and morphological changes following severe acute pancreatitis and compares patients managed by operative and non-operative methods. Association between morphological changes and functional parameters were studied. Materials and methods: 35 patients with one year of follow up after recovery from attack of acute pancreatitis were evaluated. Results: Etiology was alcohol in 19, gallstones in 11 and idiopathic in 5. Fourteen patients were managed non-operatively and 21 operatively. Patients in non-operative group had a mean follow-up of 18.4 +/- 8.2 months while patients in necrosectomy group had 31.4 +/- 20.6 months. 40% patients had exocrine insufficiency (abnormal fecal fat) while 48.5% patients (17/35) had new onset diabetes. 90% patients had morphological changes in pancreas. Exocrine abnormality was significantly higher in necrosectomy group compared to non-operative group (57.2% vs 14.1%, p = 0.01). Patients undergoing necrosectomy had higher incidence of endocrine dysfunction (61.9% in surgery and 28.5% in non-operative group (p = 0.053)}. Operative group had more number of patients with completely non-visualized main pancreatic duct (MPD) (p = 0.028) and non-operative group had significantly higher irregular MPD (p = 0.021). Exocrine dysfunction was more in patients with complete non-visualization of MPD and/or incompletely visualized MPD (p = 0.013). Conclusion: Patients managed non-operatively had significantly less exocrine and endocrine dysfunction compared to operated patients. Exocrine dysfunction was significantly associated with complete non-visualization of MPD and/or incompletely visualized MPD. Copyright (C) 2015, IAP and EPC.
