Treatment-Based Three-Dimensional Classification and Management of Anorectal Infections

A mini-invasive procedure for the treatment of supralevator abscess of cryptoglandular origin by extrasphincteric extension: preliminary results at 1-year follow-up

AIM

The aim of this retrospective study is to evaluate the preliminary results of a mini-invasive procedure for the treatment of supralevator abscesses (SLA) of cryptoglandular origin by extrasphincteric extension.

METHOD

In this clinical study, an innovative two-stage procedure was tested for the surgical treatment of SLA. As first step and as a preparation for surgery, the interventional radiologist positioned a CT-guided percutaneous perianal guidewire inside the abscess cavity under local anesthesia. As second step, the surgeon performed an abscess incision and drainage around the guidewire, with a complete debridement of all the necrotic tissue. If a complex anal fistula was identified, a loose seton was placed in situ.

RESULTS

Nine patients, comprising 5 men (55%) and 4 women (45%), underwent the above-mentioned two-stage procedure to treat SLA of cryptoglandular origin. Median age was 32 years (range, 25-42 years). A silicone draining seton was placed during the surgical procedure in 5 patients (55%), since a coexisting fistula was also revealed by surgery. A repeat surgery, along with a new drainage procedure, was required in one patient out of nine (11.1%) for a complete wound healing. The complete wound healing was achieved after a median of 30 days (range, 26-38). At the 1-year follow-up, the healing rate was 89%.

CONCLUSIONS

The treatment of SLA of cryptoglandular origin by using this innovative two-stage procedure may be a safe and convenient surgical option to effectively decrease the risk of recurrence and anal sphincteric injuries.

Rectal inclusion cyst as a complication of stapled hemorrhoidopexy: A case report

RATIONALE

Stapled hemorrhoidopexy is gaining popularity for prolapsing hemorrhoids. However, like any other operation, there is always the potential risk of complications. Rectal inclusion cysts are rare complications that results from the potential space in the staple line.

PATIENT CONCERNS

A 49-year-old woman was admitted to our hospital with a complaint of anorectal pain and fever complaints after stapled hemorrhoidopexy. The endoanal ultrasonography showed unclear fluid containing a cystic lesion circuit to the rectum at the staple line.

DIAGNOSES

The endoanal ultrasonography strongly indicates the rectal inclusion cysts.

INTERVENTIONS AND OUTCOMES

A full thickness excision of the cyst was carried out along the staple line. The patient had complete recovery, with no recurrence or complaints for at least 6 months after the surgery.

LESSONS

Endosonography has an important role in investigating symptomatic patients after stapled hemorrhoidopexy. Once an inclusion cyst is diagnosed, excision of the stapled line is the only choice of treatment.

Understanding and Treating Supralevator Fistula-in-Ano: MRI Analysis of 51 Cases and a Review of Literature

BACKGROUND

Supralevator fistulas are highly complex. The delineation of the supralevator fistula has become accurate because of MRI.

OBJECTIVE

The aim of the study was to analyze the pathophysiology and treatment of different types of supralevator fistulas.

DESIGN

This was a prospective study.

SETTINGS

The study was conducted at a specialized fistula treatment center in North India.

PATIENTS

All of the patients with fistula-in-ano who presented in the outpatient department were assessed with a physical examination and MRI scan. The patients in whom the supralevator extension was confirmed on MRI were included in the study.

MAIN OUTCOME MEASURES

The MRI scans of patients included in the study were analyzed in detail to assess the types of supralevator fistulas and other characteristics of these fistulas. The patients who were operated on were followed for cure rate and deterioration in incontinence.

RESULTS

Of 702 patients with fistula-in-ano who were analyzed by MRI over a period of 3 years, 51 patients with supralevator fistula-in-ano were identified. The mean age was 44.3 ± 12.1 years and the male:female ratio was 16:1. The incidence of supralevator fistulas was 7.26% (51 of 702). In supralevator fistulas, the supralevator extension (upper part) was found to be in the intersphincteric plane in all of the patients. This upper part could be successfully managed by laying it open through the transanal route. The infralevator (lower) part could be of 3 types: intersphincteric (n = 13), low transsphincteric (n = 3), or high transsphincteric (n = 35). The lower part could be managed conventionally. There were no extrasphincteric fistulas. An extensive review of the literature revealed only 2 studies (total fistulas = 16) in which supralevator fistula was studied.

LIMITATIONS

This was a retrospective study.

CONCLUSIONS

The upper supralevator extension in all of the supralevator fistulas is almost always in the intersphincteric plane. This upper part could be laid open through the transanal route. The lower infralevator part could be of 3 types, intersphincteric, low transsphincteric, or high transsphincteric, which could be managed conventionally. Thus, supralevator fistulas could be managed successfully and easily. See Video Abstract at http://links.lww.com/DCR/A630.
