Active clinical trials for "Rectal Neoplasms"

This study aim to determine if a different surgical technique could result in a lower anastomotic leak rate. The two techniques are equally used around the world and well described by the international literature but this is the first study that compare the two techniques.

The wide application of ISR and DST has greatly improved the anal preservation rate for low rectal cancers, but the technical difficulty has also been obviously increased because of the limited pelvic space. Although many scholars have tried to solve this problem, all the methods have failed to fundamentally solve the problem of "the oblique dissection" of the distal rectum. To solve the problem above, the director of this clinical trial has explored a new distal rectal resection method-- transanterior obturator nerve gateway approach. The purpose of this clinical trial is to prospectively collect and compare data on the patients' perioperative variables and postoperative functional and oncological outcomes of this novel approach with the traditional approach to confirm the safety and feasibility of this novel approach and its advantages over the traditional approach.

This multicentre randomized controlled trial aims to investigate whether an abbreviated MRI is comparable to a combined single venous phase CT with an additional 3 min equilibrium phase of the liver, in the pretreatment radiological workup in patients with rectal cancer.

The goal of this clinical trial is to compare in newly diagnosed patients with resectable rectal cancer with lateral lymph node metastasis. This study aims to further verify the safety and efficacy of FOLFOXIRI three-drug regimen Using multiple omics techniques to identify and confirm specific molecular markers Participants will be treated with FOLFOXIRI three-drug combination regimen. Researchers will compare another group treated with conventional preoperative chemoradiotherapy to see if the experimental group is superior to the control group in terms of 3-year disease free survival, local recurrence rate, lateral lymph node positivity rate, and 5-year overall survival rate.

The loop ileostomy is an effective method used to bypass faecal contents and reduce the sequelae of possible anastomotic leakage. I t is most often performed after a low anterior resection indicated for lower-middle rectal cancer. A second operation is required for closure, with a morbidity of about 25%. Many studies have been completed in order to detect possible risk factors - both patient-related and surgery-related - for complications in ileostomy closure surgery. Currently, there is a lack of research studies focused on the preoperative management of these patients. Our purpose is to reduce the complication rate by optimizing the preoperative status of the distal ileum and to analyze its impact on the reduction of postoperative ileus. Main objective: To assess whether efferent loop stimulation two weeks before ileostomy closure decreases the incidence of postoperative paralytic ileus.

This phase II trial is assessing how 64Cu-ATSM (64Cu-copper(II) diacetylbis(N4-methylthiosemicarbazone)) PET/CT scan could predict neo adjuvant treatment response in rectum cancer locally advanced

This study is a randomized, double blind controlled trial examining the impact of incorporating a single intraoperative intravenous magnesium bolus and infusion into a preexisting Enhanced Recovery After Surgery (ERAS) protocol for colorectal surgery in place of preoperative oral pregabalin. These protocols are pathways designed with the goal of achieving early surgical recovery by utilizing a constellation of perioperative care techniques that include the use of opioid-sparing pain medications, minimally invasive approaches, and prevention of post-operative nausea and vomiting, among others. Intravenous magnesium has shown to be an effective non-opioid analgesic in abdominal surgeries that decreases total opioid consumption, pain, and improves recovery. The purpose of this study is to evaluate whether or not the addition of intravenous magnesium to our institutional ERAS protocol will improve specific outcome measures, and provide additional benefits when compared to oral preoperative pregabalin. The primary outcome is the patient's quality of recovery based on the "Quality of Recovery - 40 Questionnaire" (QOR 40), and secondary outcomes will be opioid consumption, pain, shivering, sedation scores, acute kidney injury, gastrointestinal function, respiratory function, and hospital length of stay.

The purpose of this study is to determine whether 3 months of neoadjuvant CapOx is non-inferior to neoadjuvant radiotherapy in patients with moderate risk CRM"-" mid rectal cancer.

The purpose of this study is to determine whether the addition of 2 cycles of induction CapOx chemotherapy and 2 cycles of consolidation CapOx chemotherapy to standard chemoradiation improves 3-year disease-free survival in patients with locally advanced CRM"+" mid and low rectal cancer.

The purpose of this study is to determine whether 4 cycles of neoadjuvant CapOx chemotherapy is more effective than the upfront surgery in patients with intermediate risk CRM"-" mid and upper rectal cancer.
