Video-assisted anal fistula treatment combined with anal fistula plug for treatment of horseshoe anal fistula

Abstract

Objective Horseshoe anal fistula is a common anorectal disease, and there is no standard procedure for its treatment. In this study, we performed a modified surgical procedure for the treatment of horseshoe anal fistula and investigated its efficacy and adverse effects. Methods We retrospectively analyzed the outcomes of video-assisted anal fistula treatment combined with an anal fistula plug (VAAFT-Plug) in 26 patients with a horseshoe anal fistula. The follow-up period ranged from 6 to 18 months. Preoperative and postoperative data were collected to analyze the cure rate, anal sphincter function, and incidence of complications. Results The surgeries were successfully performed in all patients, 23 of whom were cured (effective cure rate of 88.46%). Three patients developed recurrence and were cured after traditional surgery. No patients developed severe complications or postoperative anal incontinence. The VAAFT-Plug protocol was performed with a small incision in the fistula that subsequently promoted fistula healing and preserved sphincter function. Conclusion Although randomized controlled trials will be needed to fully validate these findings, our results suggest that VAAFT-Plug represents a promising treatment strategy for horseshoe anal fistulas. This technique preserves normal anal function and achieves satisfactory outcomes in most patients.

Comparison between recent sphincter-sparing procedures for complex anal fistulas-ligation of intersphincteric tract vs transanal opening of intersphincteric space

“…Fistulotomy is the most common procedure performed for anal fistulas but fistulotomy is contraindicated in complex fistulas as the risk of sphincter injury is high[ 2 ]. Therefore, several new sphincter-sparing procedures have been developed over the last two decades like video-assisted anal fistula treatment (VAAFT)[ 3 - 7 ], anal fistula plug (AFP)[ 8 , 9 ], over the scope clip (OTSC)[ 10 - 12 ], fistula laser treatment (FiLac)[ 2 ], stem cells[ 13 , 14 ], fixcision[ 15 ], fibrin glue[ 16 - 18 ], ligation of intersphincteric fistula tract (LIFT)[ 19 - 25 ], Bio-LIFT[ 26 ] and transanal opening of intersphincteric space (TROPIS)[ 27 - 31 ].…”

Facile one‐pot synthesis of fluorescent aminoclay and the applications for fluorescence sensing Cr2O72−

“…Hexavalent chromium (Cr(VI)) is widely used in many fields including electroplating, organic synthesis, leather tanning, textile dying, printing, steel manufacturing, etc. [1][2][3] However, Cr(VI) exhibits highly harmful, teratogenic, and potentially carcinogenic effects on living systems. Low concentrations of Cr(VI) may contribute to kidney failure and rhinitis.…”

“…To date, various approaches have been developed for sensing Cr(VI), [3] such as atomic absorption spectrum, [8] inductively coupled plasma mass spectrum (ICP-MS), [9] electrochemical methods, [10,11] ion chromatography, [12] colorimetry, [13] fluorescence, [6,14] and so on. Among these detection strategies, these traditional instrumental methods suffer from complicated operation and high costs.…”

“…[5,6] Importantly, Cr(VI) in water or soil can be enriched in crops and the human body via the food chain, directly or indirectly leading to dangerous effects on human health and the environment. [7] Therefore, the detection of Cr(VI) is of great significance.To date, various approaches have been developed for sensing Cr(VI), [3] such as atomic absorption spectrum, [8] inductively coupled plasma mass spectrum (ICP-MS), [9] electrochemical methods, [10,11] ion chromatography, [12] colorimetry, [13] fluorescence, [6,14] and so on.
