A retrospective study on the use of the Gant-Miwa procedure in conjunction with the Thiersch procedure in 31 cases of rectal prolapse was performed and completed in March 2011. We evaluated these cases after a follow-up period of more than one year. The findings revealed that: 1) the number of female cases was overwhelmingly more than that of male cases, with a male to female ratio of 16.1:83.9; 2) the mean age was 82.3±8.1 with the majority of cases being elderly; 3) the mean operative time was 41 minutes; 4) postoperative complications were observed in three cases (severe anal bleeding after defecation occurred 23 days after the operation, surgical knot appeared at the point of insertion one year later, and the surgical thread was placed on the inside of the sphincter muscle causing anal pain during defecation and difficult evacuation); and, 5) recurrence was observed in five of the cases (16.2%). The cases were then compared in terms of prolapsed bowel length of either less than 5 cm or longer. The less than 5 cm group contained 1 out of 8 cases (12.5%), and the 5 cm or longer group contained 4 out of 23 cases (17.4%).
