Efficacy comparison of optimal natural orifice specimen extraction for robotic middle rectal cancer resection in women: transanal or transvaginal orifice.
World J Surg Oncol
January 2025
Department of General Surgery, The First Affiliated Hospital, Jiangxi Medical College, Nanchang University, Nanchang, Jiangxi, 330006, China.
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.
Transanal Minimally Invasive Surgery for a Gastrointestinal Stromal Tumor of the Lower Rectum: A Case Report.
Asian J Endosc Surg
January 2025
Department of Gastroenterological Surgery, Sakai City Medical Center, Osaka, Japan.
Rectal gastrointestinal stromal tumors (GISTs) are prevalent in the lower rectum, and the existing literature suggests that transanal interventions are advantageous for anorectal preservation. Herein, we present a case of rectal GIST resection using transanal minimally invasive surgery. A 75-year-old woman reported vaginal discomfort and was subsequently diagnosed with GIST via transanal tumor biopsy.

Department of Frontier Surgery, Graduate School of Medicine, Chiba University, Chiba 260-8670, Japan.
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.
Local resection in rectal cancer: When, who and how?

Article Synopsis
- Local resection (LR) is suitable for stage T1N0M0 rectal cancer without unfavorable factors, using transanal endoscopic surgery to achieve good oncological outcomes.
- Accurate staging in specialized colorectal units is crucial for determining appropriate treatments, with total mesorectal excision (TME) being standard for more advanced tumors but linked to significant risks and functional impacts.
- New organ-preservation strategies like neoadjuvant therapy with LR or a "Watch and Wait" approach after complete clinical response are being investigated as potential alternatives to TME, though challenges remain.
Transanal vs Laparoscopic Total Mesorectal Excision and 3-Year Disease-Free Survival in Rectal Cancer: The TaLaR Randomized Clinical Trial.

Importance: Previous studies have demonstrated the advantages of short-term histopathological outcomes and complications associated with transanal total mesorectal excision (TME) compared with laparoscopic TME. However, the long-term oncological outcomes of transanal TME remain ambiguous. This study aims to compare 3-year disease-free survival of transanal TME with laparoscopic TME.
