Mechanisms of primary operative failure and results of remedial operation in patients with chronic pancreatitis.

Resection and drainage operations achieve long-term pain relief in approximately 85% of patients with chronic pancreatitis (CP). In patients who develop recurrent pain, a few data exist on the long-term results of remedial operations. Over an 18-year period (1988-2006), 316 patients with CP had primary resection or drainage operations at our institution. Thirty-nine developed recurrent pain and were treated by a remedial resection or drainage operation. Patient demographics, time to symptom recurrence, radiographic anatomic abnormalities, type of remedial operation, postoperative morbidity, and long-term outcomes were analyzed. Thirty-nine patients, 56% female with a mean age of 41 years (range 16-61 years) had either remedial resection: total pancreatectomy (TP; N = 8), pancreaticoduodenectomy (PD; N = 6), distal pancreatectomy (DP; N = 5), or drainage operation: duodenal preserving pancreatic head resection (DPPHR; N = 8), revision of pancreaticojejunostomy (N = 12). TP achieved pain relief in 88% with postoperative complications greater than or equal to grade III in 38% and diabetes in 100%. Drainage operations achieved pain relief in 67% of patients with postoperative complications greater than or equal to grade III in only 8%. Partial parenchymal resections (DPPHR, PD, DP) as a remedial procedure achieved pain relief <50% of the time. Drainage procedures, when anatomically feasible, are the preferred reoperation to treat patients with recurrent pain after failed primary operation for chronic pancreatitis.
