To observe clincal curative effect of tissue-selecting therapy stapper (TST) on treating internal rectal prolapse.

The clinical data of 200 patients with internal rectal prolapse of Liaocheng People′s Hospital Anorectal Department from January 2013 to January 2015 were collected and divided into TST group (n=100) and PPH group (n=100) according to the surgical methods. The clinical efficacy and hospitalization time of the two groups were compared. The postoperative pain, urinary retention, bleeding, anal swelling and anastomotic stenosis were also compared.

The curative effects of TST group and PPH one were 81% and 79%, respectively, with no significant difference (χ²=0.13, P>0.05); hospitalization time of TST group was significantly less than that of PPH group (χ²=35.24, P<0.01); Postoperative pain (χ²_24h=5.71, χ²_48h=5.38, χ²_72h=7.73; P<0.05), urinary retention (χ²=9.28, P<0.05), bleeding (χ²=7.04, P<0.01), anastomotic stenosis (χ²=23.46, P<0.01), anal swelling (χ²=23.86, P<0.01) in TST group were all significantly lower than that in PPH one, except for 6 hour pain after surgery.

TST is effective in the treatment of rectal intussusception, with shorter hospitalization time and fewer postoperative complications.
