title: Prospective comparison of long term outcomes in patients with severe acute pancreatitis managed by operative and non operative measures.
abstract: OBJECTIVE
  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.
  
  
  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).
  
  
  CONCLUSIONS
  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.
