Comparison of the effect of laparoscopic cholecystectomy between elder and middle age

Objective To evaluate the curative difference of laparoscopic cholecystectomy (LC)between elder and middle age.Methods Patients with gallbladder disease who underwent LC from 2006 to 2011 were collected and divided into elder group (≥65 years old,35 patients) and middle age group(＜ 65years old,353 patients).The operation time,conversion rate,postoperative complications,time to first oral intake,time to first ambulation and hospitalization time were compared.These patients were divided into simple gallbladder disease group (included recurrent biliary colic,chronic cholecystitis,gallbladder polyps)and the complex gallbladder disease group (included acute cholecystitis,gallbladder empyema,acute cholecystitis perforation).The age,WBC,operation time,postoperative complicantions and hospitalization time were evaluated.Results The operation time,conversion,postoperative complications rate,time to first oral intake,time to first ambulation and hospitalization time had no significant difference between elder group and middle age group (P ＞ 0.05).The age,conversion rate between simple gallbladder disease group and complex gallbladder disease group had no significant difference (P ＞ 0.05).But the WBC,operatian time,postoperative complications,hospitalization time in simple gallbladder disease group had significant difference compared with complex gallbladder disease group [(7.32 ± 2.12) × 109/L vs.(11.35 ± 4.62) × 109/L,(62.3 ±29.5) min vs.(79.5 ±49.2) min,3.1％(10/322) vs.9.8％(5/51),(5.0 ±3.7) d vs.(7.9 ± 6.5) d,P ＜ 0.01 or ＜ 0.05].Conclusions Age is not the risk factor of LC in elderly patients,but the disease type has a significant effect on the choice of LC.
