Article Abstract
Introduction: Head-mounted mixed-reality technologies may enable advanced intraoperative visualization during visceral surgery. In this technical note, we describe an innovative use of real-time mixed reality during robotic-assisted transanal total mesorectal excision.
Technique: Video signals from the robotic console and video endoscopic transanal approach were displayed on a virtual monitor using a head-up display. The surgeon, assistant, and a surgical trainee used this technique during abdominal and transanal robotic-assisted total mesorectal excision. We evaluated the feasibility and usability of this approach with the use of validated scales.
Results: The technical feasibility of the real-time visualization provided by the current setup was demonstrated for both the robotic and transanal parts of the surgery. The surgeon, assistant, and trainee each used the mixed-reality device for 15, 55, and 35 minutes. All participants handled the device intuitively and reported a high level of comfort during the surgery. The task load was easily manageable (task load index: <4/21), although the surgeon and assistant both noted a short delay in the real-time video.
Conclusion: The implementation of head-mounted mixed-reality technology during robotic-assisted transanal total mesorectal excision can benefit the operating surgeon, assistant, and surgical trainee. Further improvements in display quality, connectivity, and systems integration are necessary.

Outcomes of the management of synchronous rectal and prostate cancer: a systematic review.
Int J Colorectal Dis

University of Aberdeen, Aberdeen, AB24 2ZD, Scotland, UK.
Background: The optimal management of synchronous rectal cancer (RC) and prostate cancer (PC) remains unclear. This systematic review evaluates treatment strategies and reports postoperative, oncological, and quality-of-life outcomes in patients treated with curative intent.
Methods: Following PRISMA guidelines, this systematic review was registered in PROSPERO (CRD42024598049).

Background: Metastases in the lateral pelvic lymph nodes or mesenteric lymph nodes represent distinct categories of mid-low rectal cancer. This study investigated the patterns of mesenteric and lateral pelvic lymph node metastases in mid-low rectal cancer; the survival benefit of postoperative treatment was also analysed in these groups.
Methods: This retrospective multicentre study included consecutive patients with mid-low rectal cancer who underwent total mesorectal excision with lateral pelvic lymph node dissection in three Chinese institutions between 2012 and 2020.

A major cause of cancer death, colorectal cancer is becoming more common in younger people. The comparative effectiveness of robotic versus laparoscopic total mesorectal excision (TME) as surgical interventions for mid-low rectal cancer following neoadjuvant chemoradiotherapy (nCRT) remains uncertain. To systematically evaluate oncological, perioperative, and survival outcomes of robotic versus laparoscopic surgery for mid-low rectal cancer following nCRT.

Background: Lateral pelvic lymph node (LPLN) metastasis is a poor prognostic factor in rectal cancer, but the optimal management strategy is debated. This multicenter retrospective study investigated the role of LPLN dissection (LPLND), with total mesorectal excision (TME), after neoadjuvant chemoradiation therapy (nCRT), aiming to identify patients who may benefit from LPLND.
Patients And Methods: A total of 559 patients with locally advanced rectal cancer and LPLN involvement from 2009 to 2018 were included (KROG 22-09).

Background: Predicting tumor regression grade (TRG) after neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer (LARC) preoperatively accurately is crucial for providing individualized treatment plans. This study aims to develop transrectal contrast-enhanced ultrasound-based (TR-CEUS) radiomics models for predicting TRG.
Methods: A total of 190 LARC patients undergoing NCRT and subsequent total mesorectal excision were categorized into good and poor response groups based on pathological TRG.
