RESUMO
Emergency conditions make laparoscopic treatment of acute cholecystitis challenging. The aim of this study is to retrospectively analyse our experience of cholecystectomy for acute cholecystitis performed between January 1995 and December 1997. In order to be included, patients had to present (i) symptoms of acute cholecystitis correlated with laboratory blood tests and ultrasonographic studies (ii) evidence of acute inflammation during the operation and (iii) histological confirmation of acute or subacute inflammation of the excised gallbladder. 192 patients were treated: 62 were totally managed laparoscopically (group CCN), 33 managed laparoscopically but required conversion to open cholecystectomy (group CCC) and 97 were managed conventionally by laparotomy (group CL). Mean age was significantly different between the three groups, (CCN: 55.6 +/- 15 years, CCC: 64.2 +/- 13 years, CL: 66.5 +/- 17 years), as was ASA score (CCN: ASA 3 and ASA 4: 16%, CCC: ASA 3 and ASA 4: 48%, CL: ASA 3 and ASA 4: 46%), and initial infectious signs (temp. > or = 38 degrees C: CCN: 35%, CCC: 39%, CL: 63%). Mean operative delay was significantly higher in the converted group [8.7 +/- 13 days (CCC) vs 4.5 +/- 8 days (CCN) and 5.4 +/- 8 days (CL)]. There were two (1%) bile duct injuries, one in the CCC group, the other in the CL group. Operative mortality was 2% (CCC: 0%, CCN: 0%, CL: 4%) and operative morbidity was 40% (CCN: 21%, CCC: 24%, CL: 57%). The mean postoperative hospital stay was shorter in the CCN group (6.5 +/- 3.5 days) and CCC group (9.6 +/- 4.4 days) vs the mean stay in the CL group (14.7 +/- 11.6 days). Appears to be beneficial for selected patients with low surgical risk to conclude laparoscopic cholecystectomy. It has yet to be shown whether this benefit can be extended to patients with a high surgical risk.
