RESUMO
Objective To explore the clinical characteristics of acute calculous cholecystitis in over 80 years old patients.Methods A retrospective study was made on the clinical data of 71 cases diagnosed as acute calculous cholecystitis and receiving surgical treatment from Sep 2006 to Sep 2016.Patients were divided into three groups:Early LC group (25 patients),PTGD group (29 patients),the staged LC group (17 patients) after PTGD.Results There was statistically significant difference in the gallbladder wall thickness,operation time and blood loss between the two LC groups.There was no statistically significant difference between the two LC groups in other baseline data and hospital stay,hospital cost,rate of postoperational complication,rate of conversion to open procedure between the two LC groups.There was statistically significant difference between the early LC group and PTGD group in the baseline data.Logistic regression analysis indicated that the TG13 grade was an important influence factor for treatment selection of PTGD (OR=3.957,P=0.015,95％CI:1.30-12.043).Conclusion Laparoscopic cholecystectomy was safe for good risk over 80 years old patients.For poor risk patients,PTGD is recommended before a LC attempt.
