Abstract:
BACKGROUND: Periampullary cancer is a relatively common malignancy, and its incidence is increasing. A pancreaticoduodenectomy is the procedure of choice in patients with periampullary cancer. However, leakage of the pancreaticojejunal anastomosis has been a major complication after a pancreaticoduodenectomy, with a frequently reported incidence of 5 percent to 25 percent. The ideal management of the pancreatic stump has not yet been determined. Thus we tried to find a safe and effective pancreatic stump management technique and to monitor the security of the pancreatic stump anastomosis by using the body fluid amylase level. PATIENTS AND METHODS: Forty six (46) consecutive patients who had undergone a pancreaticoduodenectomy, between January 1990 and January 1998, were evaluated retrospectively. Before June 1997, we did 36 pancreaticojejunostomies without long stent insertion into the pancreatic duct (group 2). After that, we did 10 P-Jstomies with long stent insertion (group 1). A long silicone stent was used for intubation of the anastomosis. Also the amount of pancreatic juice drainage from the long pancreatic duct tube was checked daily. We placed two Penrose drains and one Jackson-Pratt drain near the anastomosis. Patients were monitored for clinical evidence of a pancreatic fistula by evaluation of the amylase concentration in serum and the peritoneal drainage at postoperative day 7. The normal range of body fluid amylase was defined to be within five times of the normal serum amylase level. Cholangiography, which was obtained through a T-tube or a percutaneous transhepatic catheter, was performed on postoperative day 7 and was used to assess to leakage from or the obstruction at any of the three reconstructive anastomoses. RESULTS: In group 1, there was no leakage from the P-Jstomy site. The daily mean pancreatic juice amount and body fluid amylase level were 76.6 ml/day (range, 0.4-137.4 ml/day) and 147.4 U/L (range,44-323 U/L). In group 2, there were 4 cases of leakage at the P-Jstomy site (11.1%). CONCLUSION: An external long pancreatic duct stent insertion is an effective and safe method for management of a pancreatic remnant. We could check the amount of the daily pancreatic juice precisely. Effective decompression of the P-Jstomy was achieved by long stent insertion. We could monitor the security of the pancreatic stump anastomosis by the body fluid amylase level. We suggest that our method, which monitors the body fluid amylase level, is effective in early detection and treatment of P-Jstomy site leakage. The effort to find the best method for management of the pancreatic remnant should be continued.
