Filter by:Primary Endpoint: The main objective of this National Registry is to identify the incidence and to analyse the risk factors for anastomotic leakage in rectal cancer surgery From the operational point of view, the aim of this Registry is to systematize the collection of information on the different surgical services. This Registry claims to have National audit functions, allowing thus the knowledge of the procedures performed at each center that could enable the establishment of the best standard of care. Secondary Endpoints: To determine the real incidence of anastomotic leakage according to the different locations and techniques: uniform definition of anastomotic leakage. To analyze the preoperative risk factors of anastomotic leakage: PATIENT FACTOR. To analyse the variability in the practice of rectal anastomosis: SURGEON FACTOR. To analyse the influence of different stapling devices in rectal anastomosis: INSTRUMENTAL FACTOR To know the current treatment of anastomotic leakage and the associated morbidity and mortality. To create and validate an anastomotic leakage predictive Score.
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.
Esophageal resection becomes a routine surgical procedure in many medical centers. Usually reconstruction after esophagectomy is achieved by gastric pull-up with cervical or intrathoracic anastomosis. The only blood supply for this gastric tube is by right gastroepiploic arcade. Bad or borderline perfusion of gastric tube is the main reason for future anastomotic leaks or strictures. The investigators suggest to measure components of venous blood gases (O2, pH, CO2, lactate) from the area of future anastomosis before construction of gastric tube and just before creation of anastomosis ( after 15-30 minutes), compare the results of this analysis with systemic venous blood. The investigators suppose that elevation of acid features of blood (pH decreasing, lactate increasing etc.) as expression of tissue ischemia after gastric tube creation maybe the significant predictive sign for future anastomotic leaks or strictures. After operation the investigators plan to find relationship between the blood gas changes and rate of anastomotic leak and stricture. This is prospective study. Anticipated cohort of 50 patients
The purpose of this registry is to collect data on the clinical use of endoluminal vacuum (E-Vac) therapy to treat both upper and lower intestinal leaks and perforations.
Anastomotic leak is a devastating complication of colorectal surgery. There is no widespread means of assessing the viability of a laparoscopic anastomosis. The investigators described recently the feasibility of microvascularisation assessment with near-infra red technology (NIR). The aim of this study is to look at the implementation of this technique in a wider prospective series of patients undergoing colorectal resection.
This is a randomized clinical trial to clarify if the delay phenomenon could reduce the incidence of oesophagogastric dehiscence after an esophagectomy for esophageal cancer comparing an experimental group vs control group. The delay phenomenon will be performed by an arteriographic approach.
Esophageal cancer (EC) is the eighth most common cancer and the sixth leading cause of cancer deaths worldwide. Minimally invasive esophagectomy (MIE) is regarded as a safe and effective management for resectable EC. Gastric tube is considered to be an ideal substitute for the resected esophagus, and used for cervical esophagogastric anastomoses for digestive tract reconstruction in MIE. However, the tension at the anastomosed area can not be ignored and may cause cervical anastomotic leakage (CAL) in some cases. Continuous neck flexion is a standard post-operative posture after tracheal resection and reconstruction, and aimed to relieve the anastomotic tension. In this study, the investigators attempt to adopt the maneuver in MIE, and observe its effect on relieving the anastomotic tension and decreasing the incidence of CAL.
The purpose of this study is to determine whether reduced rectal blood flow is associated with the extent of surgery when performing an operation to remove rectal cancer. The investigators also aim to describe any relation of reduced rectal blood flow, as well as raised inflammatory biomarkers in blood and tissue, to the occurrence of anastomotic leakage. The patients will be recruited at Umeå University Hospital and all patients who are planned to undergo anterior resection for rectal cancer and able to consent are eligible for this study. Rectal blood flow measurements will be conducted with Laser-Doppler technology using noninvasive measuring probes. Preoperative and postoperative blood sampling as well as postoperative drain fluid collection will take place. Perianastomotic tissue will also be collected. In the postoperative period, any occurrence of surgical complications especially anastomotic leakage, will be noted. Blood flow and biomarkers will be assessed in relation to type of mesorectal excision (total or partial) and correlated to anastomotic leakage. Standard statistical tools will be utilized, such as parametric, non-parametric tests and logistic regression, as appropriate. The study will recruit approximately 40 patients during three consecutive years.
Evaluating predictive value of serum procalcitonin, C-Reactive Protein, drain IL-6 and TNF-alpha for anastomotic leakage in post-operative period.
Rationale: Colorectal cancer is the fourth most common cause of cancer death worldwide, estimated to be responsible for almost 610,000 deaths in 2008. Surgery remains the predominant curative treatment type for colorectal cancer, but has a major impact on the patient's wellbeing by demanding large amounts of metabolic reserves. This can lead to the development of frequently observed and severe postoperative complications. The most important complication after colorectal surgery is anastomotic leakage (AL), which has an incidence of 8-15% in the Netherlands. AL is associated with high short-term mortality rates of up to 40%. Even though many attempts have been made to reduce the incidence of this dreaded complication, none of these interventions have been successful so far. Despite proper patient selection and improvement in surgical techniques, the percentage of AL has been stable for years. Objectives: To investigate whether recently identified patient-specific factors can predict the occurrence of anastomotic leakage in patients undergoing elective surgery for colorectal cancer. Study design: Prospective observational study Study population: Adult colorectal cancer patients undergoing elective surgery. Main study parameters/endpoints: Primary endpoint: AL within 30 days postoperatively Secondary endpoints: Intestinal microbiome in fecal sample, I-FABP, SM22, Calprotectin, C-reactive protein(CRP), Citrullin, complement factors in blood, VOCs in exhaled air, COX-2 & MBL polymorphisms in buccal smear, L3-index & atherosclerosis measurements on CT-scans, SNAQ & MUST scores
