The expansion of the indications for laparoscopic surgery to include high-risk patient, acute and malignant pathology, and more complex procedures may prolong the hospital stay. Cox multiple stepwise regression analysis model was employed to determine independent predictors of prolonged postoperative hospital stay (more than 3 days) following advanced laparoscopic procedures among 10 variables.Some 130 patients had undergone advanced laparoscopic surgical procedures between November 2000 and August 2003. The median postoperative hospital stay was 3 days (interquartile range 2-5), and 81 patients (62.3%) were discharged within 3 days of surgery. The independent predictors of prolonged postoperative hospital stay were ASA score of 3 or 4 (odds ratio [OR] = 4.610, P = 0.0002) and preoperative hospital stay (OR = 0.151 per day, P = 0.001). Independent predictors of duration of preoperative hospital stay were emergency admission to hospital (OR = 9.516, 95% CI 5.770-13.261, P < 0.0001) and an underlying malignant pathology (OR = 7.948, 95% CI 3.623-12.273, P = 0.0004). Advanced laparoscopic surgery is associated with a short postoperative hospital stay in the majority of patients. Prolongation of the postoperative hospital stay (more than 3 days) may be expected if the patient had been in the hospital with an acute or malignant disease for more than 6 days prior to surgery and in patients with high comorbidity. The duration of surgery has no impact on the duration of the postoperative hospital stay.
