Application of pancreatic stents in chronic pancreatitis / 中华消化内镜杂志

ABSTRACT

Objective The clinical efficacy of pancreatic stent in treating chronic pancreatitis was summarized. Methods The stents were applied in 14 patients with chronic pancreatitis and ductal stricture manifested clinically and roentgenographically. Postoperative abdominal pain, changes in appetite, body weight and fat in stools were observed in follow－ ups. Results The stents, 5～ 10F in caliber, were successfully placed in all patients with first attempt. They were followed up for 210 days ( ranging 28～ 520 days ). The early (3 months ) results showed that the pain remitted in 13/14 (92.9％ ) and 11/13 (84.6％ ) of cases respectively. While abdominal pain persisted in 2 cases inspite of the stents. Along with pain remission the appetite and presence of fat in stools improved associated with increase in body weight. The stents drainage maintained for a median to 256 days (ranging 90～ 520 days) Transient hyperamylasemia occurred in 3 cases. Translocation and occlusion of the stent was found in 1 occasion each on the 98 and 520 day respectively. No other serious complication was detected. Conclusion It is assumed that pancreatic stent is effective to treat chronic pancreatitis with ductal stricture.
