• Records from 87 consecutive patients undergoing lateral pancreaticojejunostomy (LPJ) for chronic pancreatitis were reviewed to determine the incidence of pseudocyst and the safety of combined pancreatic duct and pseudocyst drainage. Twelve patients had undergone previous pancreatic pseudocyst drainage; four of them also had pancreatic pseudocysts present at the time of LPJ. In addition, 22 patients had pseudocysts identified preoperatively and/or confirmed at operation. The overall incidence of pseudocyst was 39%. Twenty-six patients (group 1) underwent pancreaticojejunostomy combined with pseudocyst drainage. Sixty-one patients (group 2) underwent pancreaticojejunostomy only. Operative morbidity and mortality results (19% and 8%, respectively, in group 1; 18% and 2%, respectively, in group 2) were similar. Patient outcome was also similar in the two groups (81% and 84% of patients obtained pain relief in groups 1 and 2, respectively). There were no pseudocyst recurrences in either group. Thus, there is a high incidence (39%) of pancreatic pseudocyst in patients undergoing LPJ for chronic pancreatitis. Combined drainage of the pancreatic duct and pseudocyst is safe and effective.
