Background: Postoperative rectovaginal fistula leads to a loss of patients' quality of life and presents significant challenges to the surgeon. The literature focusing specifically on postoperative rectovaginal fistulas is limited. The objective of the present study is to identify factors that can enhance the success of the management of this postoperative rectovaginal fistula.

Background: Pilonidal disease (PD) is a common condition for which the global incidence is increasing. Surgery is the currently preferred approach to treatment but there is a growing interest in new minimally invasive techniques, such as sinus laser therapy (SiLaT).

Aim: Our primary objective was to assess the efficacy of SiLaT for the treatment of pilonidal disease.

Article Synopsis
  • High-resolution anoscopy (HRA) is essential for detecting and treating precursors of anal squamous cell carcinoma (ASCC), and AI algorithms can effectively distinguish between high-grade and low-grade squamous lesions in HRA images.
  • A deep learning system using a convolutional neural network (CNN) was developed, trained on 151 HRA exams comprising over 57,000 images to automate the differentiation between high-grade squamous intraepithelial lesions (HSIL) and low-grade lesions (LSIL).
  • The CNN achieved high accuracy rates, with an overall accuracy of 94.6%, and demonstrated sensitivity and specificity of 93.6% and 95.7%, respectively, indicating its potential to improve early

Article Synopsis
  • High-resolution anoscopy (HRA) is crucial in identifying precursors to anal squamous cell carcinoma, and AI models show potential for improving this process, though previous studies haven't looked at how staining and anal manipulation affect them.
  • A convolutional neural network was created using 27,770 images to distinguish between high-grade and low-grade lesions, achieving an impressive overall accuracy of 98.3% across various image subsets.
  • The AI demonstrated standout sensitivity and specificity, and its effectiveness varied based on the type of staining used, suggesting that AI could significantly enhance the accuracy and efficiency of HRA procedures in real time.

Anal squamous cell carcinoma (ASCC) is a rare gastrointestinal malignancy associated with high-risk human papillomavirus (HPV) and is currently one of the fastest-growing causes of cancer incidence and mortality in developed countries. Although next-generation sequencing technologies (NGS) have revolutionized cancer and immuno-genomic research in various tumor types, a limited amount of clinical research has been developed to investigate the expression and the functional characterization of genomic data in ASCC. Herein, we comprehensively assess recent advancements in "omics" research, including a systematic analysis of genome-based studies, aiming to identify the most relevant ASCC cancer driver gene expressions and their associated signaling pathways.

Aim: The aim of this study was to evaluate the real-life clinical and radiological efficacy of darvadstrocel injection into complex perianal fistulas in Crohn's disease. Secondary endpoints were to assess symptomatic efficacy, adverse effects and factors associated with complete combined clinical-radiological response (deep remission).

Methods: After marketing the product in France, all first patients treated consecutively were included.

MANAGEMENT OF SECONDARY LESIONS IN ANO-PERINEAL CROHN'S DISEASE. Anoperineal involvement in Crohn's disease is common and affects around 1/3 of patients during their disease. It constitutes a pejorative factor with an increased risk of permanent colostomy and proctectomy and is associated with a major deterioration in quality of life.

Anal squamous cell carcinoma (ASCC) is a rare malignancy with a rising incidence associated with human papillomavirus (HPV) infection. The locally advanced disease is associated with a 30% rate of treatment failure after standard chemoradiotherapy (CRT). We aimed to elucidate the prognostic factors for ASCC after curative CRT.

Article Synopsis
  • The study focuses on the management of ano-rectovaginal fistulas (ARVF) resulting from obstetrical anal sphincter injury (OASIS), aiming to identify factors influencing surgical success.
  • A total of 60 patients were reviewed, revealing a 91.7% overall success rate in managing ARVF, though only 37.2% of specific surgical procedures were successful.
  • The research indicates that while a diverting stoma isn't necessary for improved outcomes, the Martius flap and Musset procedures yield better results than the less invasive endorectal advancement flap (ERAF) in cases involving sphincter injuries.

Purpose: We conducted a prospective study to evaluate a new hemorrhoidal bleeding score (HBS).

Methods: All consecutive patients who had consulted between May 1, 2016 and June 30, 2017 for bleeding hemorrhoidal disease were prospectively assessed at a proctological department. The study was conducted in 2 stages.
