New stitching method may speed up gallstone surgery
NCT ID NCT07345663
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 360 patients who had gallstone removal surgery with a T-tube drain. Doctors compared a new continuous stitching method to the traditional interrupted stitch for closing the bile duct. The goal was to see which method is faster and just as safe. Results could help surgeons choose the best technique.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- modified continuous suture (using barbed polydioxanone sutures) versus interrupted suture
- What this could lead to
- If the modified continuous suture is faster and just as safe, it could become the preferred method for closing the bile duct during laparoscopic stone removal surgery.
- What could go wrong
- This is a retrospective observational study, not a randomized trial, so results may be influenced by patient selection. The findings are about surgical technique, not a new treatment for the disease itself.

Who is studied
The study population consists of patients who underwent laparoscopic common bile duct exploration (LCBDE) with T-tube drainage at our institution between January 2020 and November 2024. Inclusion criteria include patients who had choledochotomy closure performed with either modified continuous suturing (MCS) or interrupted suturing (IS). Patients were retrospectively reviewed, and baseline characteristics such as age, gender, stone burden, and ASA classification were collected. Exclusion criteria include patients with incomplete data or those who underwent procedures other than LCBDE.
