Advances in the surgical management of rectal cancer have placed the quality of total mesorectal excision (TME) as the major predictor in overall survival. A standardized TME technique along with quality increases the percentage of patients undergoing a complete TME. Quality measurements of TME will place increasing demands on surgeons maintaining competence with present and future techniques. These efforts will improve the outcome of the rectal cancer patients.

Background: Preoperative chemoradiotherapy combined with total mesorectal excision (TME) is a standard treatment for locally advanced rectal cancer (LARC). However, lateral pelvic lymph nodes (LPLNs) are often inadequately treated with standard regimens. This study examines the treatment and postoperative outcomes in LARC patients receiving a simultaneous integrated boost (SIB) for LPLNs during long-course chemoradiotherapy.

Background: The watch-and-wait strategy provides an opportunity to pursue non-operative management in rectal cancer patients with clinical complete response after neoadjuvant therapy. The management of those with near complete response remains controversial.
Objective: We assessed the oncologic outcomes of patients managed by watch-and-wait versus total mesorectal excision according to clinical response to neoadjuvant therapy.

Background: Low anterior resection (LAR) is the gold standard for curative cancer treatment in the middle and upper rectum. In radically operated patients, the local recurrence rates with total mesorectal excision (TME) after 5 and 10 years was<10%, with 80% in 5 years survival. Anastomotic leakage (AL) affects 4%-20% of patients who underwent LAR.

Background: Lymphadenectomy for rectal cancer is clearly defined by total mesorectal excision (TME). The analogous surgical strategy for the colon, the complete mesocolic excision (CME), follows the same principles of dissection in embryologically predefined planes.
Method: This narrative review initially identified key issues related to lymphadenectomy of rectal and colon cancer.

In recent years, robotic assistance has become increasingly used and applied in minimally invasive surgeries. A new cooperative surgical robot system that includes a joystick-guided robotic scope holder was developed in this study, and its feasibility for use in minimally invasive abdominal surgery was evaluated in a preclinical setting. The cooperative surgical robot consists of a six-degree-of-freedom collaborative robot arm and a one-degree-of-freedom bidirectional telescopic end-effector specializing in surgical assistance.
