A matched-cohort analytic study was performed to assess the influence an po
stoperative morbidity and on long-term outcome of gall-bladder perforation
(GP) during laparoscopic cholecystectomy (LC) and to determine the existenc
e of risk factors of GP. A total of 1127 consecutive patients who underwent
successful LC were included. AII patients received a preoperative dose of
intravenous antibiotic. If GP occurred, free bile was aspirated, the abdomi
nal cavity was irrigated, spined stones were retrieved whenever possible, a
nd antibiotic treatment was prolonged. Intraoperative GP occurred in 131 ca
ses (11.6%). The Cox multivariate proportional hazards model showed that th
e surgeon's experience was the only factor associated with a higher risk of
GP (p < 0.0001). Patients who had GP were retrospectively matched with 131
patients who did not have perforation. Statistical differences between the
two matched groups were found for the median length of surgery 74 minutes
in the GP group versus 61 minutes, p < 0.01). No differences were found far
(1) postoperative complications and reoperations (3.8% in GP group vs. 6.1
% and 0% in GP group vs. 0.8%, respectively); or (2) mean postoperative hos
pital stay (2.9 +/- 2.3 days in GP group vs. 2.6 +/- 1.6 days). No late con
sequences occurred that could be attributed to intraoperative GP. The resul
ts suggest that the frequency of GP during LC tends to diminish as the surg
eon gains experience,vith this type of surgery. This event does not cause c
omplications if adequate prophylactic antibiotic therapy is administered; s
pilled stones are retrieved whenever possible, and the abdominal cavity is
abundantly irrigated.
