BACKGROUND AND STUDY AIMS: Several precutting techniques have been described in cases of failed access to the common bile duct. We describe our experience with pancreatic sphincter precutting in an upward direction, and report its success rates and complications. PATIENTS AND METHODS: A total of 172 patients underwent a procedure using this technique between January 1989 and December 2001. The technique consisted of a medium-to-large precut along the midline, above the papillary elevation, using either the common channel or the pancreatic duct in the ampulla of Vater as a guide. The septum between the pancreatic duct and the bile duct was removed and separate openings to the pancreatic and bile ducts were created, followed by complete biliary sphincterotomy. RESULTS: Biliary cannulation and sphincterotomy was successful in 163 of the 172 study patients (95 %). Mild complications, which were all managed conservatively, occurred in 17 patients (10 %). This complication rate was significantly higher than our complication rate for standard endoscopic sphincterotomy, which was 0.8 % in 1770 patients ( P < 0.0001). CONCLUSIONS: Pancreatic sphincter precutting is an effective and safe technique for patients in whom selective cannulation of the common bile duct has failed. Further prospective comparative studies of other precutting techniques will better define its clinical value.

SOD is a challenging condition that is difficult to diagnose and treat. The high failure rate of endoscopic and surgical treatment reflects the difficulties in establishing accurate diagnosis and the lack of specific objective criteria by which appropriate therapy could be determined. In general, sphincter ablation should be offered for type I patients. An initial trial of medical therapy is appropriate for type II patients with mild-to-moderate symptoms and for all type III patients. SOM is highly recommended for type II patients and is mandatory for all type III patients if sphincter ablation is contemplated. Other causes of abdominal pain such as chronic pancreatitis or functional disorders should be considered in patients not benefiting from sphincter ablation. All procedures on the sphincter should be undertaken with caution after meticulous investigation, and patient selection should be based on strict objective criteria.
