Male gender: Risk factor for severe symptomatic cholelithiasis

The aim of this study was to determine the effect of male gender on the clinical presentation of symptomatic cholelithiasis. Laparoscopic cholecystectomy (LC) has been accepted as standard procedure for the management of symptomatic cholelithiasis even when the gallbladder is acutely inflamed. With the accumulated experience in the management of acute cholecystitis, some factors including male gender were recognized to influence the clinical presentation of symptomatic cholelithiasis and increase the conversion rate during LC. This retrospective study tried to clarify the correlation between male gender and the clinical presentation of symptomatic cholelithiasis. The medical records of all patients presenting with symptomatic cholelithiasis from January 1994 to August 1999 were evaluated. These cases were divided into four groups as follows: (1) elective LC group: patients with a history of biliary colic or acute attack of cholecystitis but whose LC was performed electively without any inflammatory change in the gallbladder during operation; (2) acute L group: patients presenting with acute cholecystitis, and LC was performed successfully without conversion; (3) acute conversion group: patients who underwent LC during the course of acute cholecystitis but the procedure were disturbed by severe inflammatory change so the), were converted to open surgery; (4) acute open group: patients whose acute cholecystitis was managed by direct open surgery due to the preoperative prediction that LC would not succeed. The correlation of gender, age, and operating time were assessed among these four groups. We found that: ( I I the male/female ratio increased (in the patient group sequence of simple LC, acute LC, acute open, and acute conversion group); (2) in the -acute LC group male patients had significantly (p = 0.04, t-test) longer operating time than females; (3) although there was no significant difference between the mean age of male (55.7 +/- 13.4) and female (56.3 +/- 15.7) patients in the acute cholecystitis groups (i.e., all patients in the acute L acute conversion, and acute open groups), the distribution curve by age in male patients showed a significantly shift to a younger age compared with female patients (p = 0.009, Fisher's exact test).
