Filter by:Rectal cancer is one of the most frequent cancer diseases, with more than 1500 new cases per year in Denmark. Fortunately, if the tumor is discovered early, surgeons can remove the part of the intestine that is afflicted, and they can often sew the intestine-ends back together, forming what is known as an anastomosis. However, in 10-15% of cases, this anastomosis doesn't heal completely, leading to anastomotic leakage. This is a serious complication, with detrimental effects for the individual patient. Previous measures to avoid this complication, have proven unsuccessful. Obsidian is a mixture derived from the patients' own blood, that contains components of blood normally responsible for stopping bleeding and kickstarting the healing process. It is already used in other clinical settings and preliminary, yet unpublished, results from a pilot study have shown its promise in decreasing the risk of anastomotic leakage in rectal anastomosis. However, its use has not been examined when performing surgery for rectal cancer with minimally invasive technique, which is today's standard. The main clinical hypothesis of this feasibility study is that it is possible for colorectal surgeons to apply Obsidian successfully on the anastomotic area with minimal invasive technique, as a supplement during rectal cancer resection with anastomosis. This study will be conducted at the Department of Surgery, Aarhus University Hospital. 50 patients will be included, who will undergo minimally invasive rectal cancer surgery with an anastomosis. Right after the onset of anaesthesia, 120 ml of blood will be collected from the patient and will be processed, making a 5-6 ml Obsidian concentrate. When the tumor-bearing part of the rectum has been removed, Obsidian will be applied, according to a pre-specified protocol. If the application is deemed successful (based on predefined assessment criteria) in at least 90% of our included patients, then this study will serve as a stepping stone for a bigger study, the aim of which will be to assess if this method can indeed bring down the rate of anastomotic leakage in such patients.
Anastomotic leakage (AL) is one of the most feared intra-abdominal septic complications (IASC) after colorectal surgery. It is defined as the leak of intestinal content due to an anastomotic dehiscence. Incidence ranges from 2% to 20%. AL is usually associated to systemic inflammatory response, even if in some cases the presentation may be subclinical. Therefore, AL is suspected in patients with a strong inflammatory response and can be confirmed by imaging with contrast enhanced computed tomography (CT) scan or water-soluble contrast studies. Nevertheless, imaging has varying sensitivity and specificity and is usually performed once the patient has a clinical evidence, thus potentially delaying the correct timing for surgery. Despite several studies about this topic and the plenty of known risk factors as mentioned above, AL is still not easy to predict. Different tools other than imaging have been studied in order to make diagnosis of AL at an early stage, as the measurement of some biomarkers of inflammation in serum and in drainage fluid. Biomarkers as white cell blood count (WBC), C-reactive protein (CRP), cytokines (e.g. TNFa, IL-6, IL-1b), markers of ischemia (e.g. lactate) and procalcitonin (PCT) have been used for an early detection of AL and other intra-abdominal septic complications. The primary aim of our study was to assess the role of drainage fluid CRP and lactate-dehydrogenase (LDH) in the early detection of anastomotic leakage.
Postoperative surveillance of local metabolism of the surgical reconstruction after esophagectomy by means of Microdialysis. Dialysate is collected continuously for seven postoperative Days. Results analysed in a blinded fashion and related to the clinical outcome. Primary endpoint: anastomotic leakage
Anastomotic leak (AL) is a breakdown of a suture line in a surgical anastomosis with a subsequent leakage of the luminal content. Anastomotic leakage occurs commonly in rectal and esophageal anastomosis than the other parts of the alimentary tract due to technical difficulties in accessing these areas and their easily compromised blood supply. Anastomotic leakage is the most feared complication following rectal resection and anastomosis. The incidence of anastomotic leakage ranges from 2.8% to more than 15%, with mortality rate more than 30%. Subclinical anastomotic failure may occur in up to 51% of patients. Anastomotic leakage leads to increase the rate of secondary interventions, re-operations, longer postoperative hospital stay, increased cost, and major impact on the patient's quality of life. In the medium to long term, patient may be unfit for post-operative adjuvant therapy with decreased the disease survival. Furthermore anastomotic leakage itself may increase the local recurrence, a reduction in overall survival, and a large proportion of patients are left with a permanent stoma.
The rate of anastomotic leakage after laparoscopic anterior resection（LAR） for medium & low rectal cancer is still high. the transanal drainage tube (TDT) was thought to be useful for deduce the rate. There were several studies, but most of them were not randomized controlled trial (RCT) studies. There was only one RCT study with enough samples, but it was designed for open anterior resection, and the patients underwent diverting stoma were excluded, so there was the selection bias. LAR now is thought to been with the same effect, and it is safe and feasible. So a RCT investigation for the use of TDT for prevention of anastomotic leakage after LAR for medium & low rectal cancer is needed.
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
Postoperative anastomotic leakage is a serious complication in patients with oesophageal or cardia cancer. Early diagnosis and treatment are mandatory. The primary aim of the present study is to investigate the clinical use of mediastinal microdialysis and whether is able to detect anastomotic leakage prior to the development of clinical symptoms.
Anastomotic leakage is a major complication in esophageal surgery. Although contrast swallow is the current standard to exclude anastomotic leakage postoperatively, endoscopy may be superior. This is the first study to compare radiographic contrast study and endoscopy for the identification of local complications after subtotal esophagectomy.
