AIM:To evaluate the outcome of laparoscopic cholecystectomy(LC)in patients aged 80 years and older.

METHODS:A total of 353 patients aged 65 to 79 years(group 1)and 35 patients aged 80 years and older(group 2)underwent LC.Patients were further classified into two other groups:those with uncomplicated gallbladder disease(group A)or those with complicated gallbladder disease(group B). RESULTS:There were no significant differences between the age groups(groups 1 and 2)with respect to clinical characteristics such as age,gender,comorbid disease,or disease presentation.Mean operative time,conversion rate,and the incidence of major postoperative complications were similar in groups 1 and 2.However,the percentage of high-risk patients was significantly higher in group 2 than in group 1 (20.0%vs 5.7%,P<0.01).Group A comprised 322 patients with a mean age of 71.0±5.3 years,and group B comprised 51 patients with a mean age of 69.9±4.8 years.In group B,mean operative time (78.4±49.3 min vs 58.3±35.8 min,P<0.01),mean postoperative hospital stay(7.9±6.5 d vs 5.0±3.7 d, P<0.01),and the incidence of major postoperative complications(9.8%vs 3.1%,P<0.05)were significantly greater than in group A.The conversion rate tended to be higher in group B,but this difference was not significant. CONCLUSION:Perioperative outcomes in elderly patients who underwent LC seem to be influenced by the severity of gallbladder disease,and not by chronologic age.In octogenarians,LC should be performed at an earlier,uncomplicated stage of the disease whenever possible to improve perioperative outcomes.展开更多

METHODS: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (Group A). These patients were compared with 19 patients under 65 years of age who were managed with surgical biliary bypass (Group B). In addition, the results for group A were compared with those obtained from 17 patients, 65 years of age or older (Group C), who received percutaneous transhepatic biliary drainage to evaluate the quality of residual life. RESULTS: Five patients (26.0%) in Group A had complications, including one intraabdominal abscess, one pulmonary atelectasis, and three wound infections. One death (5.3%) occurred on postoperative day 3. With respect to morbidity, mortality, and postoperative hospitalization, no statistically significant difference was noted between Groups A and B. The number of readmissions and the rate of recurrent jaundice were lower in Group A than in Group C, to a statistically significant degree (P = 0.019, P = 0.029, respectively). The median hospital-free survival period and themedian overall survival were also signifi cantly longer in Group A (P = 0.001 and P < 0.001, respectively). CONCLUSION: Surgical palliation does not increase the morbidity or mortality rates, but it does increase the survival rate and improve the quality of life in elderly patients with unresectable pancreatic head cancer.展开更多
