[Critical considerations on the use in instrumental divulsion of the papilla in surgery of the bile ducts. Long-term results in 103 cases].

With a view to carrying out a critical review of the use of instrumental divulsion in surgery of the bile ducts, a long-term follow-up was made, from one to 12 years after performance of this operation, in 103 out of 157 cases. An examination of the immediate results which were favourable, in contrast with those found at long-term, led to the conclusion that this procedure was of little use and it has now been dropped both in diagnostics and, with greater reson, in treatment of benign papillary stenosis.
