RESUMEN
Objective:In order to explore the possibility of expanding the surgical indications of the ambulatory laparoscopic transcystic common bill duct exploration(LTCBDE).Methods:A retrospective case-control study analysis was performed on the clinical data of 585 patients who underwent laparoscopic transcystic common bill duct exploration in the Beijing Friendship Hospital Affiliated to Capital Medical University from January 2015 to December 2018, including 155 cases of the ambulatory LTCBDE (study group) and 430 cases of the overnight LTCBDE (control group). The propensity score was used to match the related variables, and 144 pairs were successfully matched. The two groups were compared in surgery-related indicators, such the preoperative tests, history of acute exacerbation in the last one month, history of upper abdominal surgery, concomitant diseases (high blood pressure, diabetes mellitus, coronary heart disease, cerebrovascular disease and respiratory diseases), american society of anesthesiology (ASA) score, intraoperative bleeding, operation time, total medical costs, unplanned readmission rate. Measurement data with normal distribution were expressed as mean±standard deviation( ± s), chi-square test was used for comparison between groups, and M( Q1, Q3) was used for measurement data with non-normal distribution. Fisher exact probability test and Wilcoxon rank-sum test were used for comparison between groups. Results:The indexes of aspartate aminotransferase (AST), alanine aminotransferase(ALT), total bilirubin, direct bilirubin (DBIL), alkaline phosphatase (ALP), gamma glutamyl transpeptidase (GGT), ASA score, intraoperative bleeding and total medical costs of the study group were 21.8(18.0, 31.0) U/L, 21.5(15.0, 42.5) U/L, 14.2(11.2, 18.6) umol/L, 2.6(2.1, 3.5) μmol/L, 91.0(73.3, 118.5) U/L, 44.5(22.0, 109.8) U/L, 2.0(2.0, 2.0) grade, 7.5(5.0, 10.0) mL, 9 659.0(8 704.8, 10 640.2) yuan respectively, and the control group were 26.0(17.7, 45.3) U/L, 29.5(16.0, 85.5) U/L, 17.2(13.0, 27.5) μmol/L, 3.8(2.4, 8.7) μmol/L, 105.0(81.0, 156.0) U/L, 86.5(25.0, 224.8) U/L, 2.0(2.0, 2.0) grade, 10.0(6.3, 20.0) mL, 14 366.6(11 766.4, 16 764.4) yuan, which the differences between the two groups were statistically significant ( P<0.05). In two groups of the surgery-related indicators, such as the history of acute exacerbation in the last one month, history of upper abdominal surgery, hypertension are significant statistical differences ( P<0.05). Then there were no significant differences in diabetes, coronary heart diseases, cerebrovascular disease, respiratory diseases, surgical time and unplanned readmission rate. Conclusion:The concomitant diseases may not be the absolute contraindications of the ambulatory LTCBDE. More patients can be treated with ambulatory LTCBDE in experienced centers if relevant outpatient assay and examinations can be further improved, risks of surgery and anesthesia can be fully evaluated, and surgical contraindications can be clearly excluded.
