ABSTRACT
Objective:
To explore the incidence and occurrence time of gallstone disease after bariatric surgery.Methods:
Retrospectively analyzed the clinical data of 187 patients with morbid obesity who underwent bariatric surgery in the Department of General Surgery, Beijing Friendship Hospital, Capital Medical University from Dec. 2017 to Aug. 2019. All patients did not receive prophylactic ursodeoxycholic acid. All patients were underwent abdominal ultrasound and MRI examination preoperatively, and at least one abdominal ultrasound, MRI examination postoperatively. The incidence and occurrence time of gallstones and biliary sludge in patients with different bariatric surgery were analyzed respectively. Measurement data conforming to the normal distribution were described as mean ± standard deviation ( Mean± SD). Measurement data consistent with skewed distribution were described as median (lower quartile, upper quartile). Counting data were described as a percentage (%). Kruskal-Wallis test was used for comparison among groups, and then Bonferroni correction was used for pairwise comparison.Results:
The follow-up time was up to Dec. 31, 2020, with a median follow-up time of 27.0 (22.0, 31.0) months. Thirty-four patients (18.2%, 34/187) developed gallstones after bariatric surgery. Individually, it was 18.0%(30/167) in LSG group, 22.2%(2/9) in LRYGB group, 11.1%(1/9) in LOAGB group and 50.0%(1/2) in LOAGB revisional surgery group. Eighteen patients (9.6%, 18/187) were found biliary sludge formation, among which 8.4% (14/167), 22.2% (2/9), and 22.2% (2/9) underwent LSG, LRYGB, and LOAGB, respectively. The rates of weight loss and BMI loss in patients with postoperative gallstone-formation were 21.4 (18.7, 23.6)% and 21.4 (18.6, 23.5) %, respectively. Three patients (1.6%, 3/187) had newly developed symptomatic gallstones, and all of them underwent LSG. The mean occurrence time for biliary sludge and gallstone was 85.5 (28.8, 98.8) and 103.5 (93.0, 179.3) days, respectively. Statistical difference in occurrence time was only found between postoperative gallstone and biliary sludge formation ( P=0.009).Conclusion:
Without drug intervention, the incidence of gallstone after bariatric surgery was about 18.2% (34/187), which requires close clinical attention. Abdominal ultrasonography and the T2WI sequence of upper abdominal MRI can help to diagnose gallstone and monitor its changes.
