Laparoscopic cholecystectomy for acute calculous cholecystitis in elderly. More complex but equally safe and effective
Main Article Content
Abstract
AIM: Acute calculous cholecystitis (ACC) is one of the most common pathologies in the elderly. Laparoscopy is the gold standard for ACC treatment, regardless of age. This study aimed to compare different classes of elderly patients affected by ACC and assess whether laparoscopy has the same safety and effectiveness as younger patients.
MATERIALS AND METHODS: Patients aging ≠ 70 y-o presenting with ACC treated with laparoscopic cholecystectomy were prospectively enrolled from 2010 to 2020. Three groups were identified: age 70-75 (Group 1); age 76-80 (Group 2); Age > 80 (Group 3). Major postoperative complications were considered as more than grade II according to the Clavien and Dindo classification. Demographic, intra-, and postoperative outcomes were compared. A multivariate analysis was also performed to identify predictive factors of morbidity.
RESULTS: We reviewed 832 patients: 302 (36.3%) were ≠ 70 y-o. Group 1 accounted for 124 patients (41.1%), group 2 for 74 (24.5%) and group 3 for 104 (34.3%). Male gender was significantly less represented with increasing ages (p<0.001). ASA score >2 (p=0.010), CACI score (p<0.001), and ERD score (p<0.001) were more frequent in group 3.
No significant differences were found about AAST distribution and comorbidities. Conversion to open rate was significantly higher in group 1 (6.5%) and group 3 (8.7%) (p=0.019). Common bile duct stones rate was higher in group 3 (14.5% vs 13.5% vs 31.7%; p<0.001). Median postoperative hospital length of stay was increasingly longer (p<0.001).
AAST grade ≠ 3 (OR 3.187; 95% CI 1.356-7.489; p=0.008), age ≠ 70 y-o (OR 3.358; p<0.001), and CBD stones (OR 2.912; 95% CI 1.456-5.824; p=0.003) were identified as predictive factors of morbidity between < and ≠ 70 ys.
Among the three groups of elderly, age > 80 ys was associated with an increase of OR of postoperative complication by 2.94 (95% CI 1.099-7.912; p = 0.032).
CONCLUSIONS: Laparoscopy can be safely offered in elderly patients, although longer postoperative hospital stay. The presence of associated CBD stones may increase the risk of morbidity.
