Filter by:Prospective randomized controlled study, at Colon and Rectal Surgery, WMC/NYPH. Subjects undergoing Laparoscopic Left Colectomy will be randomized into 1 of 2 groups based on the instrument used for tissue dissection and vessel ligation: Group 1 - THUNDERBEAT Group 2 - Ligasure Population
The purpose of this study is to determine the short and long outcomes of the novel technique of hand-assisted laparoscopic right hemicolectomy with complete mesocolic excision and central vascular ligation for right colon cancer.
To investigate whether extended lymphadenectomy (CME) in laparoscopic colectomy could improve disease-free survival in patients with right colon cancer, compared with standard D2 radical operation.
So far, the impact of sarcopenia has been analysed only in patients undergoing traditional surgical procedures (laparotomy) or those with metastatic spread. As the ERAS protocol combined with minimally invasive access decreases postoperative metabolic disorders, it seems possible that it can limit the deleterious impact of sarcopenia as well. The aim of this study was to investigate whether the use of ERAS protocol in colorectal cancer patients influences the postoperative risk due to sarcopenia.
Uptake of colorectal cancer (CRC) screening is suboptimal in the San Francisco Health Network and access to care may be limited so novel models of health care delivery are warranted. The objective of this study is to examine whether a centralized panel management model with mailed fecal immunochemical test (FIT) will be effective at increasing the uptake of CRC screening and could be developed and sustained within the typical parameters of cost-effectiveness and budget impact analyses.
In colorectal surgery, anastomotic leak and its septic consequences still remain as the most concerning complications resulting in substantial morbidity and mortality. A common determining factor for assessing the viability of a bowel anastomosis is adequate arterial perfusion to ensure sufficient local tissue oxygenation. Intraoperative near-infrared fluorescence (INIF) imaging using indocyanine green (ICG) dye is a novel technique which allows the surgeon to choose the point of transection at an optimally perfused area before creating a bowel anastomosis. Recently, the INIF imaging system has been installed on the robotic systems and this helps identify intravascular NIF signals in real time. Although reports from several case series and retrospective cohorts have described the feasibility and safety of this imaging system during robotic colorectal surgery, to date, no studies have addressed more systematically the outcomes of this technique in robotic surgery. Considering the limitations of these reports, investigators aim to conduct a prospective randomized trial to compare robotic procedures with or without INIF imaging in patients undergoing colorectal surgery.
Background: Genes are the instructions a person s body uses to function. Genome sequencing is a new way to look at genes that your main research team is using to learn the causes of the condition they are studying. When a new cause is found this way, it is called a primary variant. Each person has many variants. Most do not cause disease. Sequencing can also find secondary variants. These are not related to the condition your main research team is studying, but may show a person to be at high risk for cancer or another condition. Researchers want to learn more about what it means to have a secondary variant. Objectives: To find new gene changes that lead to certain medical conditions. To better understand the causes of certain diseases. To learn about how people understand their genetic test results. Eligibility: People with rare diseases who have already consented to and enrolled in another protocol run by a group other than the National Human Genome Research Institute. Design: DNA samples that were already collected will be studied. Participants may be asked to send in a second DNA sample (blood or saliva). These will be used to verify any findings. If a primary variant for the participant s health condition is found through genome sequencing, this will be shared with the participant by their primary research team. If the participant has a secondary finding, it will be shared by phone call or videoconference by this research group in the National Human Genome Research Institute. Some participants may get their results in person at the clinic. Three months after getting their secondary findings, participants will do an online survey and phone interview. They will be asked about how they have used the information. Some people who do not receive a secondary finding from genome sequencing will be asked to do an online survey three months after they get that result. Participants who have a secondary finding can get genetic counseling.
The purpose of this study is to evaluate the safety and one year disease-free survival of total or subtotal colectomy and proctocolectomy in stage IIIc and stage IV epithelial ovarian, fallopian tube, and primary peritoneal cancer (EOC, FTC, PPC).
The primary objective of this double-blinded, prospective, randomized placebo-controlled study is to evaluate for change in endoscopic adenoma detection rates (ADR) with the use of peppermint oil solution vs placebo application during colonoscopy. The investigators hypothesize that ADR will be increased with the use of the peppermint oil solution and thus further reduce the risk of colon cancer by means of colonoscopy.
The purpose of this study is to compare the clinical outcomes of transanal decompression tube as a bridge to surgery with stent as a bridge to surgery for acute malignant left-sided colonic and rectal obstruction.
