A multicenter cohort study analyzed data from 1,479 patients with clinical stage II/III low rectal cancer in Japan, identifying key risk factors for local recurrence (LR). The 5-year cumulative incidence of LR was found to be 12.3%. Notable preoperative, treatment-related, and postoperative factors were linked to increased LR risk. Of particular concern, patients without neoadjuvant […]

Automated Deep Learning Framework Enhances Pelvimetry Accuracy
A novel automated pelvimetry approach using deep learning shows promise in analyzing pelvic dimensions from MRI for total mesorectal excision (TME) difficulty assessment. The framework employs a 3D U-Net to precisely localize anatomical landmarks, achieving a mean localization error of 5.6 mm and demonstrating strong correlations (0.7 to 0.87) between automated and manual measurements. This […]
Quality of life improvements for rectal cancer patients identified
Advances in rectal cancer therapies, including neoadjuvant treatments and organ-preserving strategies, have led to enhanced quality of life (QOL) for patients. Key assessments, such as the FACT-C scale and EORTC’s QLQ-30, reveal that factors like tumor location and treatment types significantly influence QOL. Intriguingly, strategies like “watch-and-wait” have shown promise in improving functional outcomes. Surgical […]
Indocyanine Green Tattooing Enhances Tumor Localization in Surgery
Preoperative indocyanine green tattooing significantly enhances the accuracy of tumor localization during robotic-assisted rectal surgery. By utilizing the fluorescence properties of this dye, surgeons can effectively identify tumor sites, mitigating the challenges posed by traditional methods like india ink tattooing and clipping. This innovative approach not only improves surgical precision but also reduces intraoperative risks […]
Minimally invasive surgery for colorectal cancer is on the rise.
Between 2010 and 2020, minimally invasive surgery for colorectal cancer surged, with robotic procedures showing significant growth. Open surgeries decreased across all facilities, while total minimally invasive surgeries surpassed open techniques from 2013 onward. Colon cancer treatments saw laparoscopic surgeries peak at 54.0% in 2016, whereas robotic surgery for rectal cancer climbed to 48.8% by […]
Cold snare polypectomy shows superior safety for small polyps
A comparison of polypectomy techniques reveals that cold snare polypectomy (CSP) offers a significantly safer alternative to hot snare polypectomy (HSP) for polyps under 10 mm. While both methods have similar efficacy, CSP reduces risks of adverse events like bleeding and perforation. With most colorectal polyps being less than this size, adopting CSP could notably […]
Preoperative CT reconstruction enhances outcomes in right colectomy.
A systematic review and meta-analysis involving 420 patients revealed that preoperative navigation using CT reconstruction significantly reduced blood loss and operative time while increasing lymph node harvest during right colectomy with complete mesocolon excision. The analysis showed a marked decrease in blood loss (p=0.002) and operative time (p
Orthodontic rubber bands enhance colorectal ESD training efficiency
Orthodontic rubber band-assisted colorectal endoscopic submucosal dissection (ORB-ESD) significantly improved trainees’ procedure times, matching expert levels. The study found that ORB-ESD shortened colorectal ESD procedure duration (28.0 min) compared to conventional methods (41.0 min). Furthermore, resection speed, visual field exposure, and muscle injury rates were better in the ORB-ESD group compared to conventional trainees, suggesting […]
Darvadstrocel shows improved long-term effectiveness for complex perianal fistulas
A recent study indicates that darvadstrocel (DVS) outperformed standard of care (SOC) in treating complex perianal fistulas in Crohn’s disease, with patients experiencing shorter times to remission and longer intervals before relapse. Among 513 patients analyzed from both clinical trials and real-world data, a significantly higher proportion achieved clinical and patient-centric remission at 24 and […]
Surgical navigation enhances successful lymph node removal outcomes
Surgical navigation significantly improves successful retroperitoneal lymph-node dissection outcomes, achieving an 85% success rate compared to 50% in conventional methods. The trial, involving 69 participants, demonstrated that navigation aided surgeons in localizing targeted lymph nodes more effectively. Both complication rates were similar across both groups, and surgeons rated the navigation system favorably. These findings indicate […]
