Background: No standard treatment for anorectal fistula cancer, such as multidisciplinary therapy, has been established due to the rarity of the disease. Herein, we investigated patients with cancer associated with anorectal fistula who underwent surgery to clarify the clinicopathological characteristics and to propose future perspectives for treatment strategies.
Case Presentation: Seven patients with cancer associated with anorectal fistula who underwent rectal amputation in our institute were analyzed with regard to clinical characteristics, pathological findings, surgical results, and prognosis. Four cases had Crohn's disease as an underlying cause. All seven cases were diagnosed as advanced stage. Preoperative [F]-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography/computed tomography (FDG-PET/CT) showed abnormal FDG accumulation in six cases including four mucinous adenocarcinomas. Three cases that received preoperative hyperthermo-chemoradiotherapy achieved pathological R0 resection. Postoperative recurrence was observed in four cases including three with Crohn's disease and one resulting in death.
Conclusions: Anorectal fistula cancer is rare and difficult to be diagnosed at early stages. Mucinous adenocarcinoma associated with anorectal fistula tends to exhibit abnormal FDG accumulation by FDG-PET/CT unlike common colorectal mucinous adenocarcinoma. Preoperative hyperthermo-chemoradiotherapy may be effective in obtaining pathological complete resection.

This study aims to mine and analyze adverse events (AEs) of Vedolizumab based on the FAERS database to better understand its safety and potential risks in the real world. Data from the second quarter of 2014 to the third quarter of 2023 were collected, employing various signal mining methods such as Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayesian Geometric Mean (EBGM). The study gathered 14,753,012 reports of AEs, of which 46,726 were related to Vedolizumab.

Background: The main goals of surgery for fistula-in-ano are to completely resolve the condition and maintain optimal anal function. Effective management of the internal opening during and proper postoperative drainage of the intersphincter plane are crucial for achieving successful outcomes. This study evaluated the clinical efficacy of a novel sphincter-sparing technique for treating high transsphincteric anal fistula (HTAF).

Background: Perianal fistula is one of the complications of deepened anal fissure. The present case-control study aimed to assess the risk factors of fissure-associated fistulas due to the limited available evidence.
Methods: Patients with fissure-associated fistulas were considered as case, and patients with anal fissure who were undergoing medical treatment without any previous anorectal surgeries were considered as control group.

Normal anal sensibility can be present in ARM patients diagnosed with all types of ARM after they have been treated with corrective surgery. Anal sensibility was better in those with a functional IAS. This means that the IAS, present in the distal end of the fistula, should be spared as much as possible to preserve anal sensibility.

Benign anorectal diseases represent a prevalent and intricate category of gastrointestinal disorders, encompassing conditions such as anal fissures, fistulas, hemorrhoids, incontinence, pain, and defecation disorders. These conditions include both anatomical abnormalities and functional disorders. Some patients continue to experience discomfort such as perianal discomfort, perineal heaviness, defecation difficulties, and abdominal bloating even after anatomical issues have been addressed, severely impairing social functioning.
