RESUMEN
Objective To investigate the causes of intractable abdominalgia after simple choleystectomy and analyse the therapeutic effect of endoscopic sphincterotomy (EST).Methods 84 patients undergoing EST were retrospectively viewed from 1987 to 1998. Results Sixty five out of 84 patients were followed up, in which the clinical signs disappeared completely in 51 cases (78%), and there were 6 cases with relapsing symptom(9%),3 cases with intermittent relapsing symptom (4%). Therapy was ineffective in 5 cases. The intractable abdominalgia is a specific sign of postcholecystectomy syndrome. EST is effective in removing the nervous structure in duodenal papilla submucosa and sphincter muscle layer responsible for abdominal pain, therefore eliminated or relived the pain.Conclusion EST has a significant effect on intractable abdominalgia after simple cholecystectomy in the majority of patients.
