ABSTRACT
Introduction: Ligation of the intersphincteric fistula tract (LIFT) is a sphincter-preserving procedure for treating anal fistula of cryptoglandular origin. Our prospective study aimed to determine the postoperative outcomes of patients undergoing LIFT in emergency and elective settings. Methods: This was a single-centre prospective observational study of the LIFT procedure for the treatment of anal fistulas. The differences in the 6-month postoperative outcomes between the emergency and elective procedures were analysed, including the healing rate, healing time, recurrence rate, recurrence time, postoperative complications and length of hospital stay. Results: Twenty-two patients were recruited for this study: 11 patients underwent LIFT as an emergency procedure (EM-LIFT), while the others underwent LIFT as an elective procedure (EL-LIFT). The healing rate for the EM-LIFT group was 90.9% (n = 10), with a median healing time of 2 months (range 0.5-4). For the EL-LIFT group, the healing rate was 100% (n = 11), with the same median healing time of 2 months (range 0.5-4). Two of the patients in the EM-LIFT group developed recurrence, with a median recurrence time of 5 months (range 4-6) and three developed recurrence in the EL-LIFT group, with the same median recurrence time of 5 months (range 4-6). There were minor postoperative complications of pain and subcutaneous infection, with no faecal incontinence. There was no statistically significant difference in postoperative outcomes between the groups. Conclusion: EM-LIFT is a feasible and safe primary procedure for active cryptoglandular-type anal fistulas.
ABSTRACT
Objectives: We studied the outcome of cutting seton in the treatment of a high transsphincteric anal fistula in Sudan. Methods: This was a prospective study of high transsphincteric anal fistulas at Kassala Police Hospital, Sudan, over the course of 24 months (2016-2017). The main outcomes measured were recurrence, incontinence and primary healing rates. Results: The cases of 72 patients treated with cutting seton for high transsphincteric fistula were analysed, with 50 (70%) of the patients being male and 22 (30%) being female. Forty-eight (66.7%) patients required two sessions of seton tightening with a duration of seton treatment of 30 days and 24 (33.3%) patients required three sessions with a duration of seton treatment of 45 days. Only one patient (1.4%) had flatus incontinence. Three (4.2%) patients had minimal bleeding from the seton site and two (2.8%) patients experienced fistula recurrence. Twenty-six (36%) patients achieved complete healing within 30 days, while 36 (54.3%) patients healed within 60 days. The remaining seven (9.7%) patients healed after 60 days. Chronic pain was reported by two (2.8%) patients after complete healing. Conclusion: In Sudan, cutting seton remains relevant, as it produces minimal incontinence with a low recurrence rate in high transsphincteric fistula treatment.
