Clinical application of ERCP concurrent laparoscopic cholecystectomy in the treatment of cholecystolithiasis complicated with extrahepatic bile duct stones

Objective

To compare the clinical efficacy of endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration and lithotomy (LCBDE) in the treatment of cholecystolithiasis combined with bile duct stones.

Methods

From September 2018 to January 2022, 195 patients with cholecystolithiasis complicated with extrahepatic bile duct stones from Department of Department of General Surgery, Shanghai Jiading Central Hospital met the inclusion criteria, including 60 cases in the LC group and 86 cases in the LCBDE group. The general condition, operation success rate, complications and residual stone rate of the two groups were retrospectively analyzed.

Results

In the simultaneous operation group, 58 patients successfully performed ERCP, and the indwelling rate of the abdominal drainage tube (41.7 % vs. 95.3 %) was significantly better than that in the LCBDE group. There was no significant difference in the conversion rate to open surgery, operation time, and intraoperative blood loss between the two groups. In the simultaneous surgery group, 4 patients (6.7 %) developed pancreatitis after ERCP, which was cured by conservative treatment. The pain score at 6 h after operation was significantly lower than that in the LCBDE group (3.9 ± 1.6 vs 6.5 ± 2.4). There were no significant differences in biliary leakage (1.7 % vs. 4.7 %), postoperative cholangitis (5.0 % vs. 5.8 %), incision infection (3.3 % vs. 3.5 %), and bile duct stone residue rate (5.0 % vs 3.5 %) between the two groups. There was no severe pancreatitis, second operation or death. The duration of hospital stay was shortened in the concurrent operation group (5.1 ± 2.3d vs 7.9 ± 3.7d), and the operation cost was significantly higher than that in the LCBDE group (48839.9 ± 8549.5 vs 34635.9 ± 5893.7 yuan).

Conclusion

ERCP combined with LC and LCBDE are both safe and effective methods for the treatment of cholecystolithiasis combined with extrahepatic bile duct stones. The simultaneous operation group has certain advantages in patient comfort and rapid rehabilitation, which can be popularized in qualified units.

Post-cholecystectomy syndrome: A cohort study from a single private tertiary center

Objectives

Although post-cholecystectomy syndrome (PCS) is a well-recognized complication, there are few reports arising from KSA. The effect of sleeve gastrectomy or endoscopic retrograde cholangiopancreatography (ERCP) stenting on the development of PCS is unknown. We aimed to measure the possible factors affecting the development of PCS, such as symptom duration, comorbidities, previous bariatric surgery, ERCP stent insertion, surgical intervention, conversion to open surgery and complication rate.

Methods

This was a prospective cohort and observational study conducted at a single, private tertiary center. We included 167 patients who underwent surgery for gallbladder disease between October 2019 and June 2020. The patients were classified into two groups according to their PCS status (PCS+ vs. PCS-).

Results

Thirty-nine patients were PCS+ (23.3%). There was no significant difference between the two groups with regards to age, gender, BMI, ASA score, smoking, comorbidities, duration of symptoms, previous bariatric surgery, ERCP, stent insertion or sphincterotomy. Chronic cholecystitis was the predominant histopathology in 83% (139/167) of patients. The most frequent causes of PCS included biliary system dysfunction, bile salt-induced diarrhea, gastritis, gastroesophageal reflux disease, and retained stones. Overall, 71.8% (28/39) of patients had incident PCS; the remaining patients had persistent PCS.

Conclusions

PCS is a neglected complication that was observed in 25% of patients mainly in the first year. Surgeon awareness can assist with patient diagnosis, preoperative selection and education. Furthermore, the history of ERCP stenting, sphincterotomy, or sleeve gastrectomy seems to be unrelated to PCS development.
