Comparison of short-term surgical outcomes between high and low tie ligation of the inferior mesenteric artery in robotic rectal cancer surgery: a propensity score matching analysis.

Robotic surgery is extensively used for rectal cancer treatment. Nonetheless, studies on whether to preserve the left colonic artery (LCA) during robotic rectal cancer surgery to reduce complications remain scarce and controversial. This study compared short-term outcomes of high tie (HT) and low tie (LT) ligation of the inferior mesenteric artery in 455 patients undergoing robotic rectal cancer surgery between May 2018 and July 2022.

Exosomal miR-106a-5p from highly metastatic colorectal cancer cells drives liver metastasis by inducing macrophage M2 polarization in the tumor microenvironment.

Background: The tumor microenvironment (TME) is a dynamic system orchestrated by intricate cell-to-cell crosstalk. Specifically, macrophages within the TME play a crucial role in driving tumor progression. Exosomes are key mediators of communication between tumor cells and the TME.

The modified Surgical Apgar Score predictive value for postoperative complications after robotic surgery for rectal cancer.

Objective: The Surgical Apgar Score quantifies three intraoperative parameters: lowest heart rate, lowest mean arterial pressure, and estimated blood loss (EBL). This scoring system predicts postoperative complications based on these measured factors. The aim of this study was to investigate the value of modified Surgical Apgar Score (mSAS) in predicting postoperative complications in patients with rectal cancer treated with robotic surgery in order to improve the survival and quality of life of rectal cancer patients.

Robotic natural orifice specimen extraction surgery versus robotic transabdominal specimen extraction surgery for early-stage rectal cancer: a multicenter propensity score-matched analysis (in China).

Background: Despite the global increase in the adoption of robotic natural orifice specimen extraction surgery (R-NOSES), its advantages over robotic transabdominal specimen extraction surgery (R-TSES) for treating early-stage rectal cancer remain debated. There is scant nationwide, multicenter studies comparing the surgical quality and short-term outcomes between R-NOSES and R-TSES for this condition.

Objective: This retrospective cohort study was conducted nationally across multiple centers to compare the surgical quality and short-term outcomes between R-NOSES and R-TSES in early-stage rectal cancer.

LASSO-based nomogram predicts the risk factors of low anterior resection syndrome for middle and low rectal cancer underwent robotic surgery.

Background: This study aims to analyze the influencing factors of postoperative Low Anterior Resection Syndrome (LARS) in patients with middle and low rectal cancer who underwent robotic surgery. It also seeks to predict the probability of LARS through a visual, quantitative, and graphical nomogram. This approach is expected to lower the risk of postoperative LARS in these patients and improve their quality of life through effective prevention and early intervention.

Transvaginal versus transabdominal specimen extraction surgery for right colon cancer: A propensity matching study.

Background: The transvaginal route for specimen extraction is considered ideal for colorectal surgery, but its safety is still questioned. There has been little research on transvaginal natural orifice specimen extraction surgery (NOSES) in the right hemicolectomy. As a result, we conducted a study comparing transvaginal NOSES to traditional transabdominal specimen extraction surgery.

Comparison of transabdominal wall specimen retrieval and natural orifice specimen extraction robotic surgery in the outcome of colorectal cancer treatment.

Background: Natural orifice specimen extraction surgery (NOSES), as a new star of minimally invasive techniques, has been increasingly favored and promoted in the field of surgery around the world. Most previous studies were comparative studies of laparoscopic NOSES and conventional laparoscopic surgery. However, there is little research on comparing robotic colorectal cancer NOSES with conventional robotic-assisted colorectal cancer resection surgery.

A nomogram and risk classification system forecasting the cancer-specific survival of lymph- node- positive rectal cancer patient after radical proctectomy.

Background: The aim of the study was to develop and validate a nomogram for predicting cancer-specific survival (CSS) in lymph- node- positive rectal cancer patients after radical proctectomy.

Methods: In this study, we analyzed data collected from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. In addition, in a 7:3 randomized design, all patients were split into two groups (development and validation cohorts).
