Transanal Opening of Intersphincteric Space for Fistula-in-Ano.

Am Surg 2021 Jan 30:3134821989048. Epub 2021 Jan 30.

Colorectal Surgery Division, The People Hospital of Guangxi Zhuang Autonomous Region, Nanning, Guangxi, China.

Background: The role of the intersphincteric space in the pathogenesis of fistula-in-ano is being increasingly recognized. Submucosal and intersphincteric rectal abscesses have been surgically managed by laying open and draining the intersphincteric space as well as by the modified ligation of intersphincteric fistula tract (LIFT) procedure. In 2017, the transanal opening of intersphincteric space (TROPIS) technique was reported for the treatment of high, complex anal fistulae. Read More

Comparative study between intersphinecteric ligation of perianal fistula versus conventional fistulotomy with or without seton in the treatment of perianal fistula: A prospective randomized controlled trial.

Ann Med Surg (Lond) 2021 Jan 18;61:180-184. Epub 2020 Dec 18.

General Surgery, Faculty of Medicine, Menoufia University, Egypt.

Background: Fistula-in-ano is one of the most common benign anal conditions in daily surgical practice.The goals in the treatment of an anal fistula are to eradicate sepsis and to eliminate the primary fistula opening, any associated tracts, and any secondary openings without a change in continence. Conventional fistulotomy (lay open of the fistula tract) is a commonly used procedure and is still relied on by the majority of surgeons as the gold standard for the treatment of perianal fistula.

Two-stage Complete Deroofing Fistulotomy Approach for Horseshoe Fistula: Successful Surgery Leaving Continence Intact.

Ann Coloproctol 2021 Jan 12. Epub 2021 Jan 12.

Sapporo Ishiyama Hospital, Sapporo, Japan.

Purpose: Surgery of the horseshoe fistula is challenging due to its complex configuration and sphincter muscle involvement. Complete deroofing fistulotomy for horseshoe fistula is highly curative with the eradication of all fistulous lesions but has been discredited for its high incontinence rate. It was replaced with the more conservative Hanley's procedure leaving the lateral tracts intact, despite its issue of recurrence. Read More

[Consensus of Chinese experts on the diagnosis and treatment of anal fistula (2020)].


Zhonghua Wei Chang Wai Ke Za Zhi 2020 Dec;23(12):1123-1130

Anal fistula is one of the most common diseases in colorectal and anal surgery. Most of them are formed after the abscess of perianal space reptures. Due to the complexity and diversity of pathological changes, the clinical efficacy of some patients is not optimistic, and there may even be serious surgical complications, including delayed healing of anal fistula or varying degrees of fecal incontinence, which significantly affect the quality of life of patients and even lead to disability.

High failure rates following ligation of the intersphincteric fistula tract for transsphincteric anal fistulas: are preoperative MRI measurements of the fistula tract predictive of outcome?

Colorectal Dis 2021 Apr 4;23(4):932-936. Epub 2020 Dec 4.

Department of Colorectal Surgery, Cleveland Clinic Florida, Weston, Florida, USA.

Aim: Treatment of transsphincteric fistulas (TSFs) with fistulotomy after an indwelling seton is tempered by risks of incontinence and litigation. Thus, ligation of the TSF tract has been popularized as an alternative option. We previously reported on 107 patients who underwent ligation of the intersphincteric fistula tract (LIFT), with a 46% failure rate. Read More

Clin Exp Gastroenterol 2020 11;13:555-567. Epub 2020 Nov 11.

Department of General Surgery, Government Medical College and Hospital, Chandigarh, India.

Anal fistulae can be a very difficult disease to manage. The management of complex fistulae is even more challenging. The risk to the fecal continence mechanism due to damage to the anal sphincters and refractoriness to the treatment (high recurrence rate) pose the two biggest challenges in the management of this disease.

The complexity of cryptoglandular fistula-in-ano can be predicted by the distance of the external opening to the anal verge; implications for preoperative imaging?

Tech Coloproctol 2021 01 12;25(1):109-115. Epub 2020 Nov 12.

Department of Surgery, ETZ (Elisabeth, TweeSteden Ziekenhuis), Doctor Deelenlaan 5, 5042 AD, Tilburg, The Netherlands.

Background: Many surgeons believe that the distance from the external opening to the anal verge (DEOAV) predicts the complexity of a cryptoglandular fistulas-in-ano and, therefore, predicts the need for additional imaging. However, there is no evidence to support this. The primary aim of this study was to determine if DEOAV can predict the complexity of a fistula. Read More

Fistulectomy and primary sphincteroplasty (FIPS) to prevent keyhole deformity in simple anal fistula: a single-center retrospective cohort study.

Acta Chir Belg 2020 Apr 15:1-6. Epub 2020 Apr 15.

Department of General Surgery, Heilig-Hartziekenhuis, Lier, Belgium.

Fistulotomy remains the gold standard for the surgical treatment of simple anal fistula, but may cause fecal incontinence and a characteristic anal 'keyhole' deformity. Although seemingly trivial, keyhole deformity may lead to bothersome symptoms such as anal pruritus and fecal soiling. This study aims to evaluate the efficacy of fistulectomy and primary sphincteroplasty (FIPS), a technique with immediate sphincter reconstruction, in the treatment of simple anal fistula and the prevention of keyhole deformity created by simple fistulotomy.

Combined Fistulotomy and Contralateral Anal Internal Sphincterotomy for Recurrent and Complex Anal Fistula to Prevent Recurrence.

Ann Coloproctol 2020 Apr 17;36(2):122-127. Epub 2020 Mar 17.

Faculty of Medicine, Universitas Gadjah Mada, Yogyakarta, Indonesia.

The ideal intervention in the treatment of perianal fistula prevents the onset of infection to speed healing and prevent fistula recurrence while maintaining the function of the anal sphincter. Currently, there is no consensus on the best recommended surgical technique for perianal fistula management. Several studies have shown that fistulotomy was an easy and safe procedure for treatment of perianal fistula. Read More
