RESUMEN
Objective To explore the effect of preoperative evaluation checklist in the preoperative preparation of laparoscop‐ic cholecystectomy .Methods Based on whether the preoperative evaluation checklist was used or not ,664 cases of patients were di‐vided into control group (n=350) and experimental group (n=314) .Routine preparation was used in the control group ,while the preoperative evaluation checklist made by department of hepatobiliary surgery in the second affiliated hospital of Chongqing medical university was added to the experimental group .The case histories of patients in both groups were retrospectively reviewed ,so as to make comparisons of the defect of preoperative preparation ,influence to operation (delay or cancel) ,comprehension of preoperative knowledge ,and score of degree of satisfaction .Results The incidence rate of the defect of preoperative preparation in the experi‐mental group (1 .59% ) was lower than that in the control group (6 .86% ) with a statistical difference (P<0 .05) .The influence to operation (delay or cancel) in the experimental group was lower than that in the control group with a statistical difference (P<0 .05) .The comprehension of preoperative knowledge and score of degree of satisfaction in the experimental groups were obviously superior to those in the control groups ,which both had a statistical difference (P<0 .05) .Conclusion The application of preopera‐tive evaluation checklist in laparoscopic cholecystectomy could benefit for sufficient preoperative preparation ,conducting surgery as scheduled ,patients′comprehension of preoperative knowledge and patients′satisfaction of medical treatment ,which deserved widely clinical generalization .
