Background/aims: To evaluate, whether the indication related varying extent of resection in chronic pancreatitis has a predictable impact on long-term outcome.
Methodology: One hundred and twenty-six patients consecutively underwent surgery for chronic pancreatitis from March 1987 to September 1997. Three treatment categories were defined: Pancreatoduodenectomy, duodenum-preserving resection and drainage procedures, and left-sided pancreatectomy. Main outcome measures were late mortality, pain scores preoperatively and at follow-up, body-weight change, percentage of insulin dependent diabetes, patient's and physician's satisfaction with surgery.
Results: Forty-one patients underwent pancreatoduodenectomy, 59 drainage procedures, and 26 left-sided pancreatectomy, respectively. Hospital mortality was 1 (2.4%), 4 (6.8%), and 1 (3.8%) (P = NS), totaling 4.8%. After an average follow-up of 5.2 years, late mortality was 10 (24.4%), 9 (15.3%), and 4 (15.4%) (P = NS) for a total of 23 (18.3%). Two patients (1.6%) died of unsuspected pancreatic cancer. Three patients (2.4%) had to be reoperated upon for pain relapse. The mean pain score was 8.8 preoperatively and 2.1 at late follow-up and not different among groups. Body-weight gain averaged 3.0, 4.0, and 3.4 kg, with no significant differences. Percentage of insulin dependency in all patients rose from 14% prior to surgery to 30% at reevaluation, and was very similar in all treatment categories.
Conclusions: The different kind and level of invasiveness of the surgical procedures did not significantly influence the late outcome. High rates of late mortality and deterioration of endocrine function are to a greater extent sequelae of comorbidity and the progression of the underlying pancreatic disease.
