Abstract:Objective：To study the microinvasive treatment of post-gastrectomy acute cholecystisis. Methods：Teweenty-eight cases of post-gastrectomy acute cholecystitis were treated by routine non-operative method first, if cases with no apparent relief after 24h of treatment were further treated with percutanous transhepatic gallbladder puncture and drainage(PTGD) guided by ultrasonography. Results：Five cases were treated by non-operative method with complete relief within 24 hours. PTGD was done successfully in all the other 23 cases.In cases with ideal bile drainage at the time of intubation, the patients had immediate marked relief of their symptoms and signs, and they fully recovered within 3~7 days.Conclusions：Ultrasound guided PTGD is an effective treatment for post-gastrectomy acute cholecystitis with the advantages of microinvasion and quick patient recovery.
