Is male gender a risk factor for conversion of laparoscopic into open cholecystectomy?

Abstract

Background: Based on a clinical observation that the conversion rate of laparoscopic cholecystectomy (LC) to open cholecystectomy (OC) is higher in males, we decided to review our records and to verify whether a significant difference in conversion rates exists between sexes.

Methods: A retrospective study on conversion rates of elective laparoscopic cholecystectomy (LC) into open cholecystectomy (LC) in relation to gender was carried out in 329 patients: 267 females and 62 males.

Results: Our data revealed that the probability of conversion is fivefold greater in males than females, 21% vs 4.5%, respectively (p = 0.0001). We attribute this striking difference to significantly more adhesions p = 0.0002) and anatomical difficulties (p = 0.003) in males during LC, leading to conversion.

Conclusions: We conclude that conversion of LC to OC is more prevalent among males and is probably attributable to a greater incidence of anatomical difficulties.
