Active clinical trials for "Rectal Neoplasms"

The clinical study of making the evidence with application of Da vinci-Robot assisted low anterior resection in rectal cancer

The purpose of this study is to investigate if operation and permanent stoma can be omitted in patients with cancer in the lower part of the rectum.

Total mesorectal excision (TME) is a rather new operation technique in the treatment of rectal cancer. It is known to reduce the rate of local recurrences. However, the influence on long-term survival is unclear.

This study aims to compare the safty and technical accessibility of linear stapler and curved cutter stapler during mid to low rectal cancer surgery.

Anastomotic leakage is a serious complication after LAR with high morbidity and mortality rates. Early diagnosis and treatment is mandatory. The primary aim of the present study is to investigate the clinical use of peritoneal microdialysis and whether is able to detect anastomotic leakage prior to clinical symptoms develops.

Introduction: In locally advanced rectal cancers (LARC), TNM staging is far from optimal. We aimed to investigate the value of previously described circulating biomarkers as predictors of prognosis. Methods: Retrospective analysis of 245 LARC patients diagnosed between January 2010 and December 2022, who underwent neoadjuvant chemoradiotherapy and surgery at two centers. A Cox regression and Kaplan-Meier analysis were performed.

DESIGN: Randomized, open-label and parallel clinical trial, assigned to early, mid, or late withdrawal of urinary catheter with a 1: 1: 1 allocation ratio. POPULATION: Patients undergoing anterior rectal resection, low rectal resection, or abdominoperineal amputation for any reason. OBJECTIVES: The main objective is to compare the incidence of acute urine retention after removal of the urinary catheter in the postoperative period of rectal resection. Secondary objectives are: Incidence of urinary tract infection after urinary catheter removal. Incidence of specific postoperative complications (Surgical wound infection, Respiratory infection, Anastomotic dehiscence, ileus). Incidence of postoperative complications assessed according to the Comprehensive Complication Index (CCI) scale. DESCRIPTION OF THE INTERVENTION: In all patients, a Rectal Resection (anterior rectal resection, posterior pelvic exenteration or abdominoperineal amputation) will be performed. In group 1A, the urinary catheter will be removed on the 1st postoperative day. In group 1B patients, the urinary catheter will be removed on the 3rd postoperative day. In group 1C patients, the urinary catheter will be removed on the 5th postoperative day. All patients will have a urine culture taken at the time of withdrawal.

This study is to investigate the role of traditional Chinese medicine (TCM) on the postoperative recovery of rectal cancer patients.

The present study aimed to review the characteristics and outcome of early-onset rectal cancer in a subset of Egyptian patients aged 40 years or less. Since the previous studies assessed this point of research in CRC overall, the investigators opted to focus upon rectal cancer alone since it may represent a separate category, distinct from colon cancer, in this age group with regards to presentation, tumor behavior, and outcome.

Anterior resection with total mesorectal excision (TME) is the standard procedure for mid and low rectal cancers . A colo-rectal anastomosis under peritoneal reflection is, most of the time, protected by a temporary loop stoma to decrease the risk and severity of anastomotic morbidity. This stoma, which is intended to be temporary, appears to be permanent in 6 to 32% of cases in the literature. The main risk factor being anastomotic leakage. Two major risk factors for anastomotic leakage after colorectal surgery are " male sex " and " Body mass index ", which are responsible of a higher anatomical difficulty (Narrow pelvis and bulky mesorectal fat) Therefore, the objective of this study is to look for a statistical link between permanent stoma and intraoperative difficulty represented by pelvic anatomical constraints.
