Laparoscopic transcystic common bile duct exploration and laparoscopic transductal common bile duct exploration in elderly patients with cholecystolithiasis combined with choledocholithiasis.

To the Editor: With the development of minimally invasive surgical technology, laparoscopic transcystic common bile duct exploration plus laparoscopic cholecystectomy (LTCBDE + LC) has become the first choice of treatment for cholecystolithiasis combined with biliary calculi. In addition, there is little prospective research.

We compared 150 patients who underwent LTCBDE + LC with 150 patients who underwent laparoscopic transductal common bile duct exploration (LTDBDE) + LC. All patients and participants were informed of the study and voluntarily provided informed consent.

There were no significant differences in the mean blood loss (38.3 ± 8.0 mL vs. 37.3 ± 8.1 mL; t = 0.89, P = 0.282), mean operation time (111.9 ± 10.2 min vs. 113.8 ± 11.2min; t = 1.63, P = 0.132), and success rate (141/150 vs. 146/150; χ2 = 2.01, P = 0.101) between the LTCBDE + LC and LTDBDE + LC groups. However, patients in the LTCBDE + LC group had a shorter stay in the hospital compared to those in the LTDBDE + LC group (4.31 ± 0.69 days vs. 4.73 ± 1.26 days; t = 2.28, P < 0.001). Patients in the LTDBDE + LC group also had a significantly lower average visual analog scale pain score at 8 h after surgery than patients in the LTCBDE + LC group (3.30 ± 1.06 vs. 2.25 ± 1.09; t = 1.86, P < 0.001). In this study, the LTCBDE + LC group experienced anal aerofluxus and removal of the drain tube earlier than did those in the LTDBDE + LC group (1.2 ± 0.4 days vs. 2.3 ± 0.5 days; t = 3.65, P < 0.001 and 2.49 ± 2.31 days vs. 3.85 ± 2.77 days; t = 2.18, P < 0.001). Additionally, patients in the LTCBDE + LC group returned to an oral liquid diet earlier than those in the LTDBDE + LC group (1.2 ± 0.4 days vs. 2.1 ± 0.4 days; t = 2.43, P < 0.001). The patients in the LTCBDE + LC group had a significantly lower total cost than that of the LTDBDE + LC group of patients (RMB 16,173 ± 558.5 Yuan vs. RMB 19,852 ± 1481.3 Yuan, t = 4.11, P < 0.001).

In the LTCBDE + LC group, with the assistance of a microincision and electrohydraulic lithotripsy, the transcystic success rate was 93.3%.

The incidence of post-operative complications in the LTCBDE + LC group was lower than that in the LTDBDE + LC group (12% [18/150] vs. 22.7% [34/150], χ2 = 6.17, P = 0.015) [Table 1].

Post-operative data and complications in the LTCBDE + LC group and LTDBDE + LC group.

The incidence of biliary leakage in the LTCBDE + LC group was smaller than that in the LTDBDE + LC group (χ2 = 4.89, P = 0.033). The LTCBDE + LC group had a significantly shorter time before resuming work compared with the LTDBDE + LC group (5.13 ± 1.05 days vs. 6.39 ± 1.15 days; t = 3.82, P < 0.001).

The procedure of LTCBDE and LTDBDE is associated with a shorter hospital stay and is more cost-effective when compared with endoscopic retrograde cholangio pancreatography (ERCP).[ The most important point is that the transcystic laparoscopic approach gains access to the CBD and avoids choledochotomy or sphincterotomy, resulting in freedom from the T-tube- or ERCP-related complications.[

This research has demonstrated that LTCBDE + LC is associated with a lower total cost, better pain scores, lower complication rate, and shorter hospital stay compared with LTDBDE + LC.
