Colorectal surgeons developed a nomogram model to predict technical challenges in performing laparoscopic sphincter-preserving radical resection for rectal cancer. Parameters such as surgical approach, intraoperative preventive ostomy, sacrococcygeal distance, and pelvic inlet diameter were identified as independent risk factors for operative difficulty. Understanding these predictive factors could aid clinicians in anticipating surgical challenges and optimizing […]

Rectal cancer patients undergoing lateral pelvic node dissection post preoperative chemoradiotherapy face high long-term complication rates, with lymphocele and anastomotic leakage as common issues. Half of them experience asymptomatic lymphoceles, mostly resolving spontaneously, while pelvic node metastases and number of nodes harvested correlate with long-term complications. Efforts to minimize complications from pelvic node dissection are […]

Study identifies preoperative factors like clinical lymph node metastasis and PET/CT status as key predictors of lateral lymph node metastasis in rectal cancer. The presence of middle rectal artery significantly correlates with pathological lymph node metastasis, particularly in the internal iliac region. Combination of clinical factors and imaging techniques shows high negative predictive value for […]

Colorectal signet-ring cell carcinoma (CSRCC) is a rare entity with poor prognosis, often diagnosed at advanced stages. Studies show an incidence of 0.1%-2.4%, associated with lower survival rates than other adenocarcinomas. Surgical intervention is challenging, and exploratory laparoscopy is advised to assess peritoneal metastases. Tailored treatment approaches are necessary due to the unique characteristics of […]
