Comparison of fully coated anti-reflux metal stenting and per-oral endoscopic myotomy in patients with achalasia: a propensity score-matched retrospective study

Table 2 The two group’s comparison of the operating time, fasting time, complications, hospitalized cost and symptoms response at 6 months after treatment

T test for Equality of means
*Fisher’s exact test, p > 0.05, no significant difference; p < 0.05, significant differences
^#Expenses include the cost of nursing, evaluation, surgery, and medication during hospitalization. The cost of long-term follow-up should be taken into account. But follow-up is mainly through telephone or WeChat contact. This cost is so low that it is negligible compared to the cost of treatment, so it is not counted
**Operating times calculated: Operation time calculation for stent placement: the time between the first gastroscopic picture and the picture after the stent is placed; POEM operation time: the time between the esophagus incision and the complete clipping of the incision
^##Dysphagia score is part of the Ecardt scores
