Background and Aims |
Peroral endoscopic myotomy (POEM) is a safe and effective endoscopic treatment for achalasia and other esophageal motility disorders, and a versatile knife (TriangleTipKnife J [TTJ]; Olympus, Tokyo, Japan) is currently widely used in POEM. Recently, we reported a novel modification of TTJ, which was adjusted to a knife length of 2 mm by attaching a disposable clip (QuickClip Pro; Olympus) sheath to the tip as a hood attachment. This study compares the safety and effectiveness of TTJ and TTJ with a hood attachment (TTJ-H) in POEM.
Methods |
This 1:1 propensity score–matched retrospective cohort study compared the procedure time, myotomy efficiency, number of coagulation forceps usage, adverse events, length of hospital stay after POEM, procedural success, and clinical success between the TTJ and TTJ-H groups.
Results |
A total of 682 consecutive patients who underwent POEM between January 2021 and June 2023 were examined. We excluded 134 patients who had already undergone POEM or laparoscopic Heller myotomy as prior myotomy. Finally, 98 propensity score–matched pairs (n = 196) were identified. The mean procedure time was shortened from 93.5 minutes to 80.2 minutes (14% reduction, P = .012) when comparing the TTJ-H group versus the TTJ group. The mean myotomy efficiency was improved from 2.76 min/cm to 2.32 min/cm (16% improvement, P ≤ .001), and usage of coagulation forceps for hemostasis was decreased from 3.87 to .55 (86% reduction, P ≤ .001).
Conclusions |
This study showed that use of TTJ-H could reduce total procedure time, improve myotomy efficiency, and reduce costs compared with TTJ.
