Case series of transpancreatic septotomy as precutting technique for difficult bile duct cannulation.

Background and study aims: Transpancreatic septotomy can be used instead of other precut techniques to facilitate bile duct carmulation after multiple failed attempts. Within the framework of a prospective randomized study on pentoxifylline, precut cases were retrospectively analyzed. Patients and methods: Of 320 endoscopic retrograde cholangiopancreatographies (ERCPs) in 306 patients with various indications who had a naive papilla, 34 cases of transpancreatic septotomy were identified and compared with 15 needle-knife sphincterotomies; six patients had received both techniques for bile duct access. Complications were defined according to consensus criteria. Results: In the 55 patients in whom precutting techniques were employed, the use of both techniques alone or in combination resulted in a final common bile duct carmulation rate of 81.8 %. Five patients developed complications (9.1 %). Of the two cases of pancreatitis (3.6%), one was mild and one severe (combined group). Of the three cases with hemorrhage, one was mild (transpancreatic septotomy) and two severe (needle knife). In patients who underwent conventional pulltype sphincterotomy (n=242), 6.2% developed complications (nine pancreatitis and six hemorrhage). Conclusion: In cases of difficult bile duct cannulation, transpancreatic septotomy seems to be a safe alternative to needle-knife precutting with reasonable success rates. It should be studied in prospective randomized trials.
