Scissor-Type Knives Show Similar Efficacy in Colorectal Endoscopic Submucosal Dissection

Scissor-type knives, clutch cutter (CC) and SB knife Jr2 (SB), demonstrated comparable efficacy in colorectal endoscopic submucosal dissection. Both groups exhibited high en bloc resection rates and low complication rates, with CC showing significantly less perioperative bleeding than SB. Risk factors for prolonged procedure time included antiplatelet use, larger lesion size, severe fibrosis, and higher […]

Neoadjuvant Chemoradiotherapy Yields 84% 3-Year Survival for T4/N2 Rectal Cancer

Neoadjuvant chemoradiotherapy followed by total mesorectal excision resulted in a 3-year overall survival rate of 84% for patients with T4 and/or N2 rectal adenocarcinoma. Achieving R0 resection improved recurrence and survival rates, with T4 disease showing worse outcomes than N2. Adjuvant chemotherapy was associated with a survival benefit in the whole cohort and the N2 […]

Robotic total mesorectal excision shows better functional outcomes in rectal cancer patients

Robotic total mesorectal excision (RTME) in patients with rectal cancer demonstrated better functional outcomes, higher lymph node yield, and more complete total mesorectal excision resections compared to transanal total mesorectal excision (TATME). Analysis of 12 studies with 3025 patients revealed no significant differences in total operative time, conversion to open surgery, or intra-operative blood loss […]

Early follow-up colonoscopy after colorectal cancer resection detects significant pathology

Follow-up colonoscopies post colorectal cancer resection found 2.7% cancer and 13.2% advanced adenomas in initial procedures. Timely surveillance detected 4.4% cancer progression. Older age, stage IV cancer, and synchronous cancers increased the odds of finding advanced neoplasia. Subsequent colonoscopies revealed 1.8% cancer and 11.4% advanced adenomas. Advanced adenomas during prior exams predicted advanced neoplasia in […]

Robotic-assisted surgery shows better outcomes in rectal cancer resection

Patients with rectal cancer who underwent robotic-assisted surgery (RAS) had a higher likelihood of ileostomy formation but experienced fewer complications, less bleeding, and improved recovery compared to laparoscopic and open surgery. RAS patients had lower rates of ileus, anastomotic leak, and reoperation, as well as a higher rate of discharge to home. Results suggest that […]

Colectomy Outcomes in the U.S. Improve Significantly from 2012 to 2020

Significant improvements in postoperative outcomes after colectomy in the United States were observed between 2012 and 2020. The adoption of quality improvement initiatives led to a decrease in postoperative length of stay, rates of surgical site infections, and pulmonary embolism. Notably, mortality rates remained unchanged. Specifically, undergoing a colectomy in 2020 compared to 2012 was […]

Younger Colorectal Cancer Patients Face Higher Stage IV Incidence and Poorer Survival Rates

Comparing patients under 40 and between 45-65 with colorectal cancer showed higher incidence of stage IV cancer in the younger group. Five-year survival rates differed significantly based on tumor stage, with younger patients having poorer prognoses. Recurrence times also varied significantly between groups. The study emphasizes the importance of early diagnosis and treatment of precancerous […]
