Purpose/Background: To investigate the clinical effectiveness of transanal opening of intersphincteric space (TROPIS) in the treatment of high intersphincteric anal fistula and suprasphincteric anal fistula.

Methods/Interventions: A total of 124 patients with high intersphincteric anal fistula and suprasphincteric anal fistula who underwent surgical treatment at the Department of Colorectal Surgery, Xuzhou Central Hospital from September 2021 to June 2023 were selected as the study subjects. The observation group (receiving TROPIS) and the control group (receiving incision-thread-drawing) had 62 cases each.The clinical effectiveness (total effective rate), surgical indicators (operation time, hospital stay, wound healing time), pain levels [visual analog scale (VAS) pain scores]on the 1st and 7th day after surgery, and anal function (Wexner incontinence score) at 3 months after surgery were compared between the two groups.

Results/Outcomes: The total effective rate was 95.2% (59/62) in the observation group and 91.9% (57/62) in the control group, with no statistically significant difference between the two groups(P>0.05) .The operation time in the observation group was longer than that in the control group,while the hospital stay and wound healing time were shorter than those in the control group, with statistically significant differences (P < 0.05).On the 1st and 7th day after surgery, the VAS pain scores in the observation group were lower than those in the control group,with statistically significant differences (P < 0.05). At 3 months after surgery , the average Wexner incontinence score in the observation group was 0 (0, 1), which was lower than that in the control group 1(0,3),with statistically significant differences (P < 0.05).

Conclusion/Discussion: TROPIS has a good clinical effectiveness in the treatment of high intersphincteric anal fistula and suprasphincteric anal fistula. Compared with incision-thread-drawing, TROPIS has less surgical trauma, less postoperative pain, and faster patient recovery.
