A retrospective multifactorial regression analysis [S. Lyass, Y. Perry, M. Venturero, M. Muggia-Sullam, A. Eid, A. Durst, P. Reissman] Background: The association between various factors and the postoperative outcome has not been thoroughly studied in laparoscopic cholecystectomy (LC). The aim of this retrospective study was to determine which factors significantly affect patients outcome after LC. Methods: The medical and operative records of all consecutive patients who underwent LC at our institution from 1991 to 1996 were reviewed. The effect of age, medical and surgical history, duration of procedure, and setup (urgent or elective) on the postoperative complication rate and on the length of postoperative hospital stay (LOS) were analyzed using multiple linear regression and logistic regression analysis. Overall, 601 patients were included in the study. Results: The factors that significantly prolonged LOS were age (p= 0.0145), acute cholecystitis (p= 0.0006), history of ischemic heart disease (p= 0.0332), and duration of procedure (p < 0.0001). A significantly higher postoperative morbidity rate was noted in patients who had a procedure longer then 2 h than in patients whose surgery required less the 2 h (13.6% vs 3.6%, respectively; p < 0.0001). Similarly, higher morbidity was noted in elderly patients than in younger patients (16% vs 6.1%; p= 0.0005). Other factors that significantly increased postoperative morbidity included acute cholecystitis (p= 0.023), a history of cholangitis (p= 0.018), and diabetes (p= 0.05). Conclusions: According to this study, advanced age, longer duration of procedure, and acute cholecystitis significantly increase both the postoperative morbidity and the LOS. History of ischemic heart disease significantly increases LOS, but does not increase morbidity after LC.
