随机方法(请说明由何人用什么方法产生随机序列):

采用混合区组随机化方法(区组长度为2、4、6的随机组合),将符合的受试者按1:1比例将总数为348例符合入选标准的受试者随机分配到改良Kono-S吻合组和传统侧侧吻合组。

Randomization Procedure (please state who generates the random number sequence and by what method):

A mixed block randomization method (with block lengths randomly combining 2, 4, and 6) will be used to randomly assign 348 eligible subjects in a 1:1 ratio to either the modified Kono-S anastomosis group or the conventional side-to-side anastomosis group.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

对受试者设盲,而无法对研究者实施者设盲。但是在记录主要观察指标时(术后吻合口再发率情况),结果评价者及分析者将对受试者的分组信息不知情,从而尽可能减少偏倚。

Blinding:

Blinding for the subjects during the study, but not for the researchers or operators. However, the outcome assessors and analysts will remain blinded to the group assignments of the subjects when evaluating the primary outcome (the incidence of postoperative anastomotic recurrence), thereby minimizing potential bias as much as possible.
