Purpose:
To compare the treatment results of needlescopic surgery with those of the conventional method for achalasia, using propensity score-matching.
Methods:
Propensity score-matching was performed based on five factors: age, gender, body mass index, extended form, and maximum expansion diameter, to extract 28 cases each for a needlescopic group and a conventional group.
Results:
There were no significant differences between the needlescopic group and the conventional group, in operative time (165 min vs. 170 min, p = 0.682), estimated blood loss (both ≒ 0 ml, p = 0.426), or post-operative hospital stay (4 vs. 4 days, p = 0.248). Although the follow-up period was significantly longer in the conventional group (6 vs. 105 months, respectively; p < 0.001), there was no difference in the post-operative symptom scores for difficulty in swallowing and chest pain or the degree of satisfaction (p = 0.563, p = 0.142, p = 0.342, respectively). Furthermore, there was no difference in the post-operative clearance rate, with both groups found to be favorable (p = 0.758, p = 0.790, p = 1.000, p = 1.000, respectively).
Conclusions:
The short-term results of needlescopic surgery for achalasia were good and equivalent to those of the conventional method.
