ABSTRACT
Background/Aim: Chronic pancreatitis (CP) is surgically treated in selected patient populations. Frey's procedure (FP) is the most commonly described procedure for CP with head mass. This study is being conducted to determine the long-term outcome and ef?cacy of FP in patients with CP in South India of various etiologies. Methods: This is a retrospective study of patients who underwent FP at our institution. Clinical features, perioperative ?ndings, and follow-up results were evaluated. A subgroup analysis of pain relief was performed between alcoholics and non-alcoholic groups and between patients receiving FP alone and FP with additional procedures. Of the 181 patients, alcohol was Results: the causative factor in 99 (54.69%), gallstones in 20 (11.04%), and idiopathic in 62 (34.25%). With a median follow-up of 43.49 months (range 12-72 months), 78 (43.09%) patients experienced complete pain relief. Due to persistent pain and the presence of preoperative diabetes mellitus (DM), pain relief in patients with postoperative complications was incomplete. New DM and exocrine dysfunction were reported in 25 years (13.81%) and 15 (8.28%) patients. Patients with a history of alcohol abuse, smoking, weight loss, and postoperative complications are associated with newly developed diabetes. FP is a Conclusion: safe surgical option for CP with acceptable perioperative complications and appropriate short-term and long-term pain management in properly selected patients. Continuous pain and preoperative DM were independent predictors of incomplete pain relief after FP. Symptoms associated with alcohol abuse, smoking, and weight loss were associated with the development of post-FP DM in the study population.
