Filter by:The purpose of the study is to determine if short-term outcomes of rectal resections after full bowel preparation (mechanical bowel preparation plus oral antibiotics) are superior to rectal resections with only mechanical bowel preparation.
Total mesorectal excision has greatly reduced the local recurrence rate of rectal cancer after colorectal surgery. Transanal total mesorectal excision(TaTME) is potentially a suitable option for patients with middle and low rectal cancer. Robotic systems are expected to develop the advantages of TaTME to overcome the limitations of laparoscopic surgery. This study aimed to investigate the safety and feasibility of robotic assisted transanal total mesorectal excision in patients with rectal cancer.
This RCT aims at assessing the effects of a pelvic drain after total mesorectal excision for mid-low rectal cancer on the rates of pelvic sepsis and anastomotic leaks.
Many of the patients operated with sphincter preservation will present an alteration of bowel function and defecation. This dysfunction is variable in its symptoms and severity, and manifests itself in the form of urgency, incontinence and fragmentation of faeces, with repeated, incomplete or difficult evacuations. The set of these symptoms constitutes what is known as anterior resection syndrome (ARS), which can negatively influence the quality of life of the operated patients and constitutes the main objective of the study to be investigated. From this study, the investigators want to evaluate the efficacy of stimulation of the efferent loop prior to the closure of the ileostomy along with rehabilitation of the pelvic floor after the closure of the ileostomy, in the quality of life of patients who underwent anterior resection of the rectum. A non-pharmacological randomized clinical trial will be conducted, comparing a control group (usual clinical practice), with respect to the experimental group where stimulation of the efferent loop will be performed prior to the closure of the ostomy along with pelvic floor rehabilitation after the closure of the latter. The main dependent variable will be the quality of life evaluated according to the QLQ CR-29 questionnaire, and secondary dependent variables will be evaluated postoperative paralytic ileus and the previous resection syndrome using the LARS scale.
The overall aim of this pilot study is to prospectively monitor programmed death-ligand 1 (PD-L1) expression dynamics in vivo, during neoadjuvant chemoradiotherapy (CRT) or short-course preoperative radiotherapy (SCPRT) in rectal and esophageal cancer by a positron emission tomography (PET) imaging approach.
To compare the open approach and the laparoscopic-assisted approach of dissection of lateral lymph nodes in low advanced rectal cancer patients with clinically suspected nodal metastases in terms of safety, technical feasibility, and patient's oncological outcomes.
This is a open-label, single-arm study to investigate the safety and efficacy of Total neoadjuvant chemotherapy with camrelizumab, an anti-PD-1 antibody drug following short course radiotherapy in patients with rectal cancer.
This research study is evaluating a program that entails remote monitoring and home-based care for people with cancer who are receiving chemotherapy, radiotherapy, or chemoradiotherapy.
A Phase II Study of Total Neoadjuvant Therapy for High-risk Locally Advanced Rectal Cancer
ERUS-3D and CMI demonstrated good diagnostic accuracy in parietal staging of rectal extraperitoneal neoplasms, however with greater efficiency of the endoscopic method. The association of studies can improve diagnostic efficacy and influence the most appropriate approach.
