Results
Among 100 randomized patients (CS group, n =50; MC group, n =50), anastomotic strictures were observed in 18 (42%) patients in the CS group and in no patients in the MC group.
There were no significant between-group differences in anastomotic leakage (CS group, 7% vs MC group, 8%; P =0.94).
Quality of life domains of dysphagia and choking when swallowing at 3 months after surgery were significantly better in the MC group than in the CS group.

Baseline Characteristics
In total, 157 patients were scheduled to undergo radical esophagectomy with cervical anastomosis using a gastric conduit for treatment of
thoracic esophageal cancer. Fifty-seven patients were excluded from the study because they did not meet the inclusion criteria (n = 47) or refused to participate (n = 10).
The remaining 100 patients were subsequently randomized to the CS group (n = 50) or the MC group (n = 50).
Seven patients in the CS group and 4 patients in the MC group were excluded because the primary endpoint was not available; the remaining 43 and 46 patients, respectively, were analyzed as the FAS.
Participant flow
The patients were randomly assigned (1:1) to either the CS or MC technique by the minimization method.
The patients was performed using either the CS technique or the MC technique.
The postoperative management was identical for the 2 groups.
After discharge, the patients returned for an outpatient visit once monthly for 3 months. They were thereafter examined at 3 and 6 months after surgery. Upper gastrointestinal
endoscopy was routinely performed at 6 months after surgery or whenever dysphagia developed. BWL and QOL (assessed by the European Organization for Research and Treatment of Cancer QOL
questionnaires, C30 and OES18 modules) were measured before surgery and at 1, 3, and 6 months after surgery.19,20 These measurements were discontinued when recurrence was observed.
Adverse events
no special instruction
Outcome measures
The primary endpoint was the incidence of anastomotic stricture. The secondary endpoints included the incidence of postoperative complications(including anastomotic leakage) and quality of life (QoL).
