There is still no gold standard regarding the optimal circumference of antireflux mucosectomy (ARMS) in patients with treatment-refractory gastroesophageal reflux disease (GERD). The aim of this study is to assess the safety and effectiveness of resection procedures when the circumferences are different.
Patients and Methods:
Thirty-two patients with treatment-refractory GERD were allocated into group A (16 cases) and group B (16 cases) by randomization. In group A and group B, a 2/3 and 1/2 circumference, 1.5 cm wide mucosal resection of the gastric cardia was performed. Health-related quality of life (HRQOL), frequency scale for the symptoms of GERD (FSSG), DeMeester scores and acid exposure time (AET) were accessed at baseline and at 24 months after treatment. Physical component summaries (PCS), mental component summaries (MCS), and RE-specific summary (RES) scores were calculated.
All patients had successful surgical procedures and no bleeding, perforation, or dysphagia occurred. The PCS, MCS, and RES scores of post-ARMS were higher than those of pre-ARMS in groups A and B, and the FSSG, DeMeester scores and AET decreased after ARMS in both groups, with differences that were statistically significant (P<0.05). The changes in PCS, MCS, RES, FSSG, DeMeester scores, and AET were greater in group A than in group B, with significant differences in PCS, MCS, RES, and FSSG scores (P<0.05), but no significant differences in, DeMeester scores and AET (P>0.05).
ARMS is an effective treatment for treatment-refractory GERD. Moreover, we recommend the 2/3 circumference, 1.5 cm wide mucosal resection of the gastric cardia.
