“…Direct insertion method or guide wire assistant method is easy to operate and saves time, combined with overtube assistant method for the difficult patients can make the overall insertion success rate reach 94.9%. At present, there are various new technologies to improve the success rate of DPOC [12, 20–23].…”

Background This study aims to evaluate the efficacy and safety of detecting and removing residual common bile duct stones (CBDS) using direct peroralcholangioscopy (DPOC) after performing endoscopic retrograde cholangiopancreatography (ERCP) for stone retrieval. Methods From January 5, 2017 to December 27, 2017, a total of 164 cases of choledocholithiasis were treated by ERCP for stone retrieval. According to the inclusion and exclusion criteria, the remaining 79 cases (39 males; mean age: 63.3 years old, range: 52–79 years old) were enrolled in the present study. The maximum transverse stone diameter was 6–15 mm (12.7 ± 4.2 mm), as determined by ERCP. Furthermore, there were 57 cases of multiple stones (number of stones: two in 41 cases, three in nine cases, and ≥ 4 in seven cases), 13 cases of post-mechanical lithotripsy, and nine cases of broken stones. Results The overall success rate of DPOC was 94.9% (75/79). Furthermore, 18.7%(14/75) of cases were directly inserted, 72%(54/75) of cases required guide wire assistance, and 9.3%(7/75) of cases were successfully inserted with overtube assistance. The average insertion time was 7–17 min (4.9 ± 2.9 min). Residual stones were detected in 19 cases (25.3%), and all of which were < 5 mm in diameter. Moreover, five cases of formed stones were removed by basket and balloon catheter, while the remaining cases were cleaned after irrigation and suction. There were no serious complications. Conclusion DPOC is safe and effective for both the detection and removal of residual CBDS after conventional ERCP.

Freehand techniques for direct cholangioscopy access have received little attention, given disappointing initial results and high perceived and/or real technical challenges. However, while pure freehand intubation appears feasible in a significant proportion of individuals, technical advancements and tricks of the trade are being developed. Along these lines, herein I present another rescue technique assisting in freehand access for direct cholangioscopy, the "balloon-catheter-cannulation technique", which may be instrumental in overcoming two major hurdles of the procedure, i.e., stable intubation of the papillary orifice with adequate orientation and scope advancement in the common bile duct vis-à-vis gastric loop formation. To further disseminate direct cholangioscopy in the endoscopy community, technical beyond technological advancements, as for instance dedicated next-generation cholangioscopes, appear essential. Herein, I present a technical case report focussing on the limitations of the pure freehand and relative advantages of the "balloon catheter cannulation-assisted" approach for direct cholangioscopy access.
