AI Article Synopsis
- Traditional laparoscopic anterior rectal resection (TLAR) is effective for rectal cancer, but can be technically challenging, particularly for total mesorectal excisions.
- A study compared robot-assisted laparoscopic anterior rectal resection (RLAR) with TLAR in 66 patients, finding that RLAR significantly reduces operative time and has a lower conversion rate to open surgery.
- While postoperative outcomes and survival rates were similar between the two methods, there was a trend suggesting better disease-free survival with RLAR, indicating its potential benefits, though more research is needed.
Article Abstract
Background: Traditional laparoscopic anterior rectal resection (TLAR) has recently been used for rectal cancer, offering good functional results compared with open anterior resection and resulting in a better postoperative early outcome. However, laparoscopic rectal resection can be technically demanding, especially when a total mesorectal excision is required. The aim of this study was to verify whether robot-assisted anterior rectal resection (RLAR) could overcome limitations of the laparoscopic approach.
Methods: Sixty-six patients with rectal cancer were enrolled in the study. Twenty-nine patients underwent RLAR and 37 TLAR. Groups were matched for age, BMI, sex ratio, ASA status, and TNM stage, and were followed up for a mean time of 12 months.
Results: Robot-assisted laparoscopic rectal resection results in shorter operative time when a total mesorectal excision is performed (165.9+/-10 vs 210+/-37 minutes; P<0.05). The conversion rate is significantly lower for RLAR (P<0.05). Postoperative morbidity was comparable between groups. Overall survival and disease-free survival were comparable between groups, even though a trend towards better disease-free survival in the RLAR group was observed.
Conclusion: RLAR is a safe and feasible procedure that facilitates laparoscopic total mesorectal excision. Randomized clinical trials and longer follow-ups are needed to evaluate a possible influence of RLAR on patient survival.

Department of Surgery, Surgical Oncology and Science, Sapporo Medical University, Sapporo, Japan.
Defecation disorders following rectal resection have long been overlooked as an inevitable surgical complication due to the lack of established diagnostic criteria or definitions. However, these disorders have been recently termed low anterior resection syndrome (LARS), which is a defecation disorder that occurs following rectal resection and impairs the patient's quality of life (QOL). The LARS score developed by Emmertsen et al.

Department of Coloproctological Surgery, Juntendo University Faculty of Medicine, Tokyo, Japan.
Objectives: This study was conducted to investigate whether preoperative or postoperative carcinoembryonic antigen (CEA) with a new cut-off value is more optimal for predicting long-term outcomes in patients with Stage II/III rectal cancer, and to investigate the effectiveness of postoperative adjuvant chemotherapy (POAC) based on the CEA values.
Methods: Serum CEA levels were measured preoperatively (pre-CEA) and postoperatively (post-CEA). The area under the receiver operating curve (AUROC) was used to determine a cut-off for CEA.
Oncologic Impact of Conservative Treatment Compared with Surgical Treatment of Anastomotic Leakage Following Colorectal Cancer Surgery: A Retrospective Study.
J Anus Rectum Colon

Department of Surgery, Ageo Central General Hospital, Ageo, Japan.
Objectives: Differences in oncological outcomes between conservative and surgical treatments for anastomotic leakage (AL) in patients undergoing colorectal cancer surgery remain unclear.
Methods: From July 2011 to June 2020, 385 patients underwent curative resection with double-stapling anastomosis for left-sided colon and rectal cancers. Among them, 33 patients who experienced AL were retrospectively evaluated and categorized into two groups: conservative (n = 20) and surgical (n = 13).
Factors Affecting the Prognosis after Primary Tumor Resection for Patients with Metastatic Colorectal Cancer with Synchronous Peritoneal Metastasis: A Multi-center, Prospective, Observational Study.
J Anus Rectum Colon
January 2025
Division of Molecular and Diagnostic Pathology, Niigata University, Graduate School of Medical and Dental Sciences, Niigata, Japan.
Objectives: To clarify the risk factors affecting prognosis after primary tumor resection (PTR) in patients with metastatic colorectal cancer with synchronous peritoneal metastasis (mCRC-SPM).
Methods: Patients were enrolled prospectively in the JSCCR project "Grading of Peritoneal Seeding in Colorectal Cancer." Factors that may influence overall survival-age, sex, location of the primary tumor, lymph node metastasis, presence of liver metastasis, degree of peritoneal metastasis, peritoneal cancer index (PCI), cancer cure, and postoperative chemotherapy-in the PTR group were examined using multivariate analysis.
Effects of Diverting Stoma Creation in Minimally Invasive Surgery for Rectal Cancer.
J Anus Rectum Colon
January 2025
Department of Coloproctological Surgery, Juntendo University Faculty of Medicine, Tokyo, Japan.
Objectives: In rectal cancer surgery, a diverting stoma (DS) is used to prevent severe anastomotic leakage (AL), peritonitis, reoperation, and longer hospitalization. DS creation has increased in the last few decades, without establishment of clear criteria for construction of a DS. Therefore, the goal of the study was to investigate the validity of DS construction based on risk factors for AL, as an approach to reduce the number of stoma creations.
