Filter by:Propose a one-piece endoscopic resection such as endoscopic submucosal dissection (ESD) rather than surgery for benign lesions and superficial T1 cancers colorectal cancers offers comparable efficacy with better tolerability. This approach is all the more in the rectum, even for giant lesions lesions (over 8cm), as rectal surgery is particularly morbid, with particularly morbid, with a functional impact that can impact, whereas rectal ESD is less prone to complications fewer complications than in the colon. Colonic ESD for giant lesions is a longer and more morbid more time-consuming and morbid than for smaller lesions, the question of colonic surgery in this indication. this indication. In order to compare the morbidity data of patients of giant lesions with those of colectomy, a control group colectomy, a surgical control group will be set up, including patients including patients having undergone surgery for in situ T1 or T2 in situ colon cancer. Surgical resections of resection of benign lesions is generally not indicated not indicated and would not provide the necessary necessary for a comparison. T3 and T4 lesions with their own their own morbidity will be excluded.
Investigators developed an online educational module (ESTIMATE) to teach Gastroenterology (GI) trainees how to estimate polyp size using a snare. Key components include video instruction and real-time feedback incorporated over a 40-item polyp size assessment test. Trainees from GI fellowship programs will be randomized to one of four groups: control (no video, no feedback), video-only, feedback-only, and video + feedback. Participants will classify polyps into one of three size categories:- diminutive (1-5 mm), small (6-9 mm), and large (≥10 mm). Primary outcome is accuracy of polyp size classification [diminutive (1-5 mm), small (6-9 mm), and large (≥10 mm)]. Secondary outcomes include accuracy of exact polyp size (in mm), cumulative accuracy (to plot learning curves), confidence level of polyp size classification, and directionality of inaccuracy (polyp size overestimation vs underestimation).
The aim of this study is to evaluate the safety and efficacy of neoadjuvant treatment with pembrolizumab before colonic resection in patients with early-stage (I-III) deficient mismatch repair (dMMR) colon cancer (CC).
The CRC DRAW study will assess the sensitivity and specificity of the blood-based, Next-Gen CRC Screening Test for the detection of CRC.
The investigators will assess and compare Surgical, pathological and oncological outcomes between two laparoscopic procedures conventional colectomy versus complete mesocolic excision for operable colon cancer cases in Upper Egypt
In this study, a randomized controlled trial was conducted on advanced colon cancer patients with preoperative tumor staging T1-4/N1-2/M0 or T4/N0/M0 to determine the effectiveness of preoperative short-term radiotherapy combined with chemotherapy and whether it can effectively reduce the postoperative local recurrence rate, so as to provide better treatment for colon cancer patients and improve the oncological treatment effect of colon cancer.
Despite modern approaches to the diagnosis and treatment of acute bowel obstruction (ABO), postoperative mortality ranges from 5 to 32%, and complications occur up 23% of cases. One of the formidable infectious and inflammatory complications of ABO is sepsis. The main component of the development of sepsis in ABO is bacterial translocation (BT). BT is the migration of intestinal bacteria or their products through the intestinal mucosa into the mesenteric lymph nodes and further into normally sterile tissues and organs. Today there are several methods for detecting BT: 1. direct method - the detection of 16s rRNA (ribosomal ribonucleic acid) in mesenteric lymph nodes (MLN); 2. indirect method - the detection of serum lipopolysaccharide-binding protein (LBP) and presepsin (Soluble CD14 subtype or sCD14-ST). The aim of this study is to determine the diagnostic and prognostic significance of bacterial translocation as a predictor of the complications development in patients with malignant and benign acute bowel obstruction by assessing the relationship of biomarkers in the systemic circulation (LBP, sCD14-ST) with the detection of microorganism genes (16s rRNA) in mesenteric lymph nodes.
Colorectal cancer arises from the mucosal layer of the colon. Current screening is performed by flexible endoscopy, which involves visual inspection of the mucosal lining of the colon and rectum with an optical camera mounted on the endoscope, with abnormal areas being biopsied. This method is somewhat limited in that there are no readily available surface pattern or morphological classification systems with adequate sensitivity or specificity to evaluate extent of submucosal invasion (deep, superficial, or none). Optical coherence tomography (OCT) using pattern recognition is a high-resolution imaging modality. There is currently an unmet need to predict depth of invasion for colonic tumors to decide on applicability of endoscopic (endoscopic submucosal dissection or endoscopic mucosal resection) vs. surgical therapy. The investigators' hypothesis is that OCT will have a higher diagnostic accuracy for determining depth of submucosal invasion compared to existing modalities. The investigators will first aim to assess the procedural feasibility and safety of using an OCT probe during routine colonoscopy with an early feasibility study. This study will identify appropriate modifications to the device and help with development of subsequent clinical study protocols. The eventual goal is to assess the diagnostic accuracy of OCT imaging for predicting depth of invasion of colonic tumors.
The purpose of this study is to further evaluate the efficacy and safety of niraparib in patients with locally advanced or metastatic solid tumors and a pathogenic or likely pathogenic tumor PALB2 (tPALB2) mutation.
In this study, the investigators will compare extracorporeal anastomosis (EA) with intracorporeal anastomosis (IA) in patients undergoing elective laparoscopic hemicolectomy for right colon cancer.
