[Results and indications of sphincteroplasty in the treatment of complicated biliary lithiasis]. / Resultados e indicaciones de la esfinteroplastia en el tratamiento de la litiasis biliar complicada.

Sphincteroplasty is an internal biliary drainage technique that, along with choledochoduodenostomy, is offered to surgeons as one of the most effective techniques. We report our results and conclusions in a two-year study of a group of 46 patients. We prefer sphincteroplasty in the majority of patients with papillary sclerosis and consider it the most anatomic and physiologic drainage technique, since it eliminates the persistence of a cul de sac and the possible reflux of intestinal contents. It also permits examination of the sphincter of the Wirsung duct. We note that the classic complications of sphincteroplasty (acute pancreatitis and posterior window syndrome) are usually due to technical deficiencies.
