Graphical Abstract Abstract PDF: Purpose
This study was conducted to evaluate the validity of a new imaging-guided, anatomy-based classification of anorectal fistulas in defining disease severity and predicting surgical outcomes.
Methods
This multicenter, retrospective cohort study analyzed data from patients with perianal fistulas who underwent surgery between 2017 and 2023. All patients underwent preoperative 3-dimensional endoanal ultrasound, with adjunctive magnetic resonance imaging performed if ultrasound indicated a complex fistula. Imaging examinations were retrospectively evaluated to categorize fistulas according to the Garg classification and the newly proposed classification system. The new classification included 6 severity grades based on the characteristics of the primary tract: submucosal, intersphincteric, low transsphincteric, high transsphincteric, multiple, and suprasphincteric/extrasphincteric. Each grade was further subdivided into 3 subtypes (A, B, C) based on the extension of secondary tracts.
Results
When compared with the new classification, the Garg classification demonstrated a slightly lower ability to predict the feasibility of fistulotomy in simple fistulas (94.2% vs 99.1%; Fisher exact test, P=0.006). A strong positive correlation was found between the surgery failure rate and the severity grade of the new classification (Spearman rho, 0.90; P<0.001), whereas the Garg classification showed a nonsignificant positive correlation with surgical failure rate (Spearman rho, 0.90; P=0.08).
Conclusion
The new imaging-guided, anatomy-based classification of anorectal fistulas demonstrates high accuracy in defining disease severity. It represents a valuable tool for preoperative grading of anal fistulas, standardizing the reporting of diagnostic imaging, and improving the communication of findings among healthcare professionals.

Anorectal benign disease

Lower pain, less itching, and faster healing after ultrasound scalpel-assisted hemorrhoidectomy using an intimate cleaner containing chlorhexidine, acid hyaluronic acid, and natural anti-inflammatories: a multicenter observational case-control study: Antonio Brillantino, Luigi Marano, Maurizio Grillo, Alessio Palumbo, Fabrizio Foroni, Luciano Vicenzo, Alessio Antropoli, Michele Lanza, Maria Laura Sandoval Sotelo, Nicola Sangiuliano, Mauro Maglio, Rosanna Filosa, Lucia Abbatiello, Maria Preziosa Romano, Luana Passariello, Pasquale Talento, Giovanna Ioia, Corrado Rispoli, Mariano Fortunato Armellino, Vincenzo Bottino, Adolfo Renzi, Carlo Bartone, Luigi Monaco, Paolino Mauro, Stefano Picardi, Maria Paola Menna, Elisa Palladino, Mario Massimo Mensorio, Vinicio Mosca, Claudio Gambardella, Luigi Brusciano, Ludovico Docimo; Ann Coloproctol. 2024;40(6):602-609.

Purpose
Postoperative pain is a major concern for patients undergoing ultrasound scalpel-assisted hemorrhoidectomy, potentially exacerbated by delayed wound healing. This study aimed to evaluate the impact of an intimate cleansing gel containing chlorhexidine, hyaluronic acid, and other anti-inflammatory agents (Antroclean Fisioderm) on postoperative pain, itching, and wound healing in patients who had undergone this procedure.
Methods
This multicenter observational case-control study involved a cohort of consecutive adult patients who underwent hemorrhoidectomy using an ultrasound device. The study compared 2 different postoperative wound management strategies over 1 month after surgery: washing with warm water twice per day (control group) versus a 2-minute topical application of intimate cleansing gel (Antroclean Fisioderm) followed by a warm water wash (intervention group).
Results
The median postoperative pain score was significantly lower in the intervention group than in the control group at each follow-up point (P<0.01). The percentage of patients reporting anal itching was also significantly lower in the intervention group than in the control group at each follow-up point (P<0.01). All patients in the intervention group achieved complete wound healing 4 weeks after surgery, compared to 88 (82%) in the control group (P<0.01). No adverse events were reported.
Conclusion
The topical application of intimate cleansing gel (Antroclean Fisioderm) twice daily for 1 month following ultrasound scalpel-assisted hemorrhoidectomy appears to be associated with faster healing, reduced pain, decreased itching, and improved quality of life, without any adverse effects. Further larger and prospective randomized trials are recommended to confirm these findings.
