Clinical Benefits of Preoperative Percutaneous Transhepatic Gallbladder Drainage in Patients Older than Sixty with Acute Cholecystitis

초록

Purpose: The purpose of this study was to evaluate the clinical benefits of preoperative percutaneous transhepatic drainage (PTGBD), especially regarding morbidity and mortality, in patients aged 60 or older with acute cholecystitis. Methods: A retrospective study was done on a series of elderly patients (＞60 years old; n=132) who had been diagnosed between January 2007 and December 2009 as having acute cholecystitis. The patients were divided into 4 groups; cases in which only laparoscopic cholecystectomy (LC) was done (Group 1, n=84), cases in which LC was done after preoperative PTGBD (Group 2, n=15), cases in which only open cholecystectomy was done (Group 3, n=23), and cases in which open cholecystectomy was done after preoperative PTGBD (Group 4, n=10). We analyzed between group differences in surgical outcomes including periods of postoperative fast and postoperative hospital stay, OP. morbidity, and open conversion rate. Results: Patients in Group 1 had fewer underlying medical problems and lower ASA scores than patients in groups 2, 3, or 4 (p＜0.05). Mean operating time in Group 2 (113.66±107.5 min) was significantly longer than in group 1 (72.02.9±34.2 min) (p＜0.05) and the open conversion rate was higher (8.33% vs 26.67%). But, blood loss (ml) and OP time in Group 2 were lower than in Group 3 or 4 (p＜0.001). Postoperative recovery progression (periods of postoperative fasting and length of postoperative hospital stay) of Group 2 were better than in groups 3 or 4 (p＜0.001). Conclusion: Pre-operative PTGBD procedures in elderly patients with acute cholecystitis is a good clinical option as a pretreatment to a cholecystitis operation.
