Abstract

Background: To study overall outcome of ESWL therapy in large pancreatic duct stone as first line therapy in chronic pancreatitis.Methods: A prospective, observational study which took place in MGM medical college and the patient were admitted in general surgery department. Patients were selected based on the inclusion criteria composed of upper abdominal pain, weight loss, oily stools and presence of pancreatic stones or ductal irregularity/ parenchymal atrophy determined by various radiological investigations.Results: In this study 11 patients with pancreatic stones were recruited in duration of 2 years. Among 11 patients included in this study 63.33% were males and 36.375% were females. The mean age of males and females were 35.57 and 40.50 years respectively. It was observed that all study subjects had abdominal pain and history of pancreatitis. 36% patient had single calculi and 64% patient had multiple calculi. 18% calculi were present in the body of pancreas and 46% calculi in head of pancreas. All these patient had undergone ESWL procedures with minimum number of 400 shocks and maximum number of 4600. Among the patients it was noted that 73% had successful complete clearance of calculi, 18% had partial clearance and 9% had no clearanceConclusions: ESWL is efficient tool for the treatment of pancreatic calculi but can be used alone it is adjunct tool to ERCP. Endoscopy, etc.
