Filter by:The problem of delayed bleeding after endoscopic resection is becoming important due to the growing number of indications for anti-aggregation or anticoagulant treatment for cardiovascular reasons in the aging populations. Previous studies have shown that in patients at high risk of bleeding, the use of (PuraStat®), a simple and easily applicable solution, decreases the rate of delayed bleeding by promoting wound healing. Various preventive treatments, such as the prophylactic use of clips, have been tried to prevent the occurrence of delayed bleeding, but to date, no treatment has clearly shown its effectiveness. In addition, preventive hemostasis with clips is difficult and costly. The main objective is to compare the efficacy of PuraStat® to the standard treatment in reducing delayed bleeding after colorectal ESD in patients at high risk of delayed bleeding. The secondary objectives are to compare the same two strategies in terms of effectiveness and side effects. The primary outcome measure is the percentage of delayed bleeding at 30 days after surgery (ESD).
This prospective, randomized, phase 2 study is conducted to evaluate the efficacy and safety of first line mCapOX plus cetuximab versus mFOLFOX6 plus cetuximab for metastatic left-sided CRC patients with wild-type RAS and BRAF genes.
The purpose of this study is to describe type and extent of psychological distress (adverse effects) in patients undergoing surgery for colorectal cancer with peritoneal metastases and after surgery for colorectal cancer with involvement of the urinary bladder.
Tumor infiltration lymphocytes (TILs) have been harvested from advanced cancer patients and constructed to knockout PD1 gene and express scFvs against both PD1 and CTALA4 and CARs against various antigens, followed by transfusion into the patients. The safety, tolerance, and preliminary clinical efficacy of the TILs will be evaluated.
Hartmann's procedure was described for the first time in 1921 as an alternative to abdominoperineal resection for the treatment of upper rectal tumours. Although Hartmann's procedure fell out of favour for rectal cancer after the introduction of restorative procedures, it remained the most common procedure in emergency setting for many years. Nowadays Hartmann's procedure is a useful procedure in selected cases e.g. severely ill patients with a high risk of anastomotic failure. However, restoring intestinal continuity for Hartmann patients is often associated with high morbidity, and about 70% will live with a permanent colostomy. Hartmann procedure' is a rapid and simple surgical technique intended to decrease perioperative morbidity and mortality. This technique is often performed by young surgeons Indeed, end colostomy may be necessary in situations where restoration of continuity is risky, either because of unfavorable local conditions or because a more definitive resection must be aborted due to hemodynamic instability. In the last decade the Hartmann's procedure has been revalued in many studies. In diverticular disease the results of DIVA arm of the LADIES trial showed that more patients in the primary anastomosis group were stoma free compared with patients in the Hartmann's procedure group. Other studies have observed no differences in major postoperative complications or postoperative mortality between patients undergoing primary anastomosis versus Hartmann's procedure. Hartmann's procedure reversals were associated with a higher risk of serious postoperative complications than were stoma reversals after primary anastomosis with ileostomy. Despite the growing evidence in favour of primary anastomosis and its inclusion as a valid treatment option for perforated diverticulitis or perforated sigmoid colon in recent clinical practice guidelines, some surgeons have been hesitant to undertake anastomosis in the setting of purulent or faecal contamination and continue to choose Hartmann's procedure to eliminate concerns about anastomotic leakage.
Immunotherapy acquired resistance was observed in clinical practice. The investigators intended to add anlotinib to PD-1 inhibitors, hoping reverse the resistance.
Anastomotic leakage (AL) is one of the major complications after gastrointestinal surgery. Compromised tissue perfusion at the anastomosis site increases the risk of AL. Indocyanine green (ICG) combined with fluorescent near infrared imaging has proven to be a feasible and reproducible application for real-time intraoperative quantification of the tissue perfusion and cohort studies showed reduced leakage rate. Unfortunately, these studies were not randomized. Therefore, we propose a nationwide randomized controlled trial to identify the value of ICG for AL in colorectal anastomosis.
After surgery for rectal cancer, many people undergo changes in bowel habits, which may include the need to empty their bowels more often, accidental leakage of stool or gas, the sudden urge to go to the bathroom, and more. The term "Low Anterior Resection Syndrome" or LARS is used to describe these symptoms. LARS has a negative impact on one's quality of life, and can lead to frustration, as there is no single intervention that has proven to be effective for LARS, and each patient has to undergo trial and error to find one's solution. As people struggle with LARS, they describe feeling hopeless and isolated. Peer support is a supportive relationship between individuals who share common experiences or face similar challenges. The goal of our study is to evaluate whether use of an online peer support application with trained mentors who themselves have lived or are living with LARS will empower patients to better manage their LARS symptoms and improve their quality of life.
A clinical trial to assess the safety and efficacy of genetically-engineered, neoantigen-specific Tumor Infiltrating Lymphocytes (TIL) in which the intracellular immune checkpoint CISH has been inhibited using CRISPR gene editing for the treatment of Gastro-Intestinal (GI) Cancer.
This study was a randomized, controled, multicenter, phase II clinical study evaluating the efficacy and safety of fruquintinib as a maintenance therapy following first-line treatment for metastatic colorectal cancer. This study will include the patients with confirmed unresectable metastatic left-sided colon cancer with RAS mutation or right-sided colon cancer who achieved stable disease (SD) or partial response (PR) or complete response (CR) via palliative first-line treatment. It's expected to include 110 patients and they will be randomly stratified at 2:1 into fruquintinib group and observation group based on whether bevacizumab is used and the primary tumor site, using the Interactive Network Response System (IWRS). The random No. corresponds to the respective patient. The enrollment time is expected to be 18 months, followed up for 24 months.
