Outcome of surgical treatment for chronic calcifying pancreatitis.

Abstract

To evaluate the short and long-term results of surgical treatment of calcifying chronic pancreatitis in our center. We studied 55 consecutive patients operated on for chronic calcifying pancreatitis during a period of 12 years. The mean follow-up period was 6.2 years. Main outcome measures were operative mortality and morbidity, degree of pain control, diabetes onset, survival, and causes of death. The etiology was alcoholic in 48 patients and idiopathic in seven patients. A resection was performed in 78% of cases and a by-pass procedure was performed in 22%. Operative mortality was 3.6%; morbidity was 21.8%. A ductal adenocarcinoma was found in 3.6% of cases. The alcohol withdrawal rate was 78%. Complete pain control was achieved in 71.4% of the patients. Among diabetes, cirrhosis, type of surgery, smoking and alcohol abuse history, only alcohol withdrawal was associated with pain control (p < 0.03). A late reintervention was needed in only one patient in the by-pass group. Five and 10-year survival rates for the entire population were 80% and 61%, respectively. Among alcohol, cirrhosis, diabetes, and type of surgery, only the former was associated with survival (p < 0.003). Five-year actuarial survival was 55.6% for patients who continued drinking compared with 86.3% for ex-alcoholics. Surgical resection should be performed when required by the anatomical conditions because it was associated with good long-term pain control and low postoperative and late morbidity. Alcohol withdrawal has a key role for effective control of pain and prolonged survival.
