At the First University Clinic for Surgery Innsbruck a benign, scarred stenosis in the anal canal was found in 14 patients between 1975 and 1981. This stenosis turned out to be the cause of an anorectal incontinence. This stenosis results in a hampering of important organs in the anal canal that are conducive to continence. Therapy, therefore, aims at a restoration of continence. Within this therapy, removal of the stenosis is the first and most important step.

Background: To extend the practicality of liquid biopsy beyond the historical HPV circulating tumor DNA (ctDNA) assays, we evaluated the clinical relevance of a novel next-generation sequencing HPV ctDNA assay in patients with locally advanced and metastatic squamous cell cancer of the anal canal (mSCCA).
Methods: ctDNA isolated from the plasma of patients with mSCCA was sequenced using a 1.4 Mb hybrid-capture target-enrichment panel covering the whole genome sequences of all 193 HPV types.

Purpose: This study aimed to determine the optimal natural orifice specimen extraction (NOSE) method for robotic-assisted mid-rectal cancer resection in women.
Methods: This retrospective propensity score-matched (PSM) study was to analyze the clinical data prospectively collected from female rectal cancer patients who underwent either robotic-assisted transvaginal specimen extraction (RATV) or robotic-assisted transanal specimen extraction (RATA) at our center between June 2016 and December 2022. The main outcome measures were urinary, anal, and sexual function.

Background: Early anal canal cancer is frequently treated with endoscopic submucosal dissection (ESD) to preserve anal function. However, if the lesion is in the anal canal, then significant difficulties such as bleeding and challenges associated with scope manipulation can arise.
Case Summary: A 70-year-old woman undergoing follow-up after transverse colon cancer surgery was diagnosed with anal canal cancer extending to the dentate line.

Lateral lymph node dissection (LLND) is getting global attention as an a surgical option to reduce local recurrence in locally advanced rectal cancer. As the transanal total mesorectal excision (TaTME) is gaining popularity worldwide, a novel LLND approach was established adopting a two-team approach that combines the transabdominal and transanal approaches using the TaTME technique. This narrative review describes the advantages, anatomical landmarks, surgical techniques, and pitfalls of transanal LLND (TaLLND).
