Identification of the internal anal opening and seton placement improves the outcome of deep postanal space abscess

Evaluation and management of perianal abscess and anal fistula: SICCR position statement

Perianal sepsis is a common condition ranging from acute abscess to chronic anal fistula. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. Surgery is the main treatment and several procedures have been developed, but the risks of recurrence and of impairment of continence still seem to be an unresolved issue. This statement reviews the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

[Seton drainage in sphincter-sparing treatment of rectal fistulas]

Sphincter-sparing procedures for rectal fistulas are becoming more popular among coloproctologists. However, the outcomes are not optimal that forces surgeons to seek new approaches in order to improve results. Seton drainage prior to radical stage is one of these methods. The effect of seton drainage on the outcomes is reviewed in the article. Elibrary, Pubmed and Google Scholar databases were analyzed. We have assessed 14 out of 151 trials for the period 1984 - 2017. There were no significant advantages of seton drainage compared with single-stage approach (χ² = 3.84, p> 0.05, RR = 0.95, CI 95% 0.84 - 1.08). The same situation is observed for mucomuscular flap bringing down to close internal fistula. Fistula healing was more common after seton drainage deployment within 4 - 8 weeks. Bringing down of the flap to anal canal should be preferred after drainage due to less incidence of recurrences. Further trials are necessary to determine advisability of seton drainage and optimal surgical approach.

Evaluation and management of perianal abscess and anal fistula: a consensus statement developed by the Italian Society of Colorectal Surgery (SICCR)

Perianal sepsis is a common condition ranging from acute abscess to chronic fistula formation. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. The key to successful treatment is the eradication of the primary track. As surgery may lead to a disturbance of continence, several sphincter-preserving techniques have been developed. This consensus statement examines the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.
