Active clinical trials for "Anastomotic Leak"

Anastomotic leakage of the pancreatojejunostomy is often discovered with considerable delay, causing severe peritonitis, hemorrhage due to erosion of vessels, sepsis, and death. Microdialysis catheters can detect focal inflammation and ischemia, and has a potential for early detection of anastomotic leakage. This observational study will examine if monitoring with microdialysis catheters can detect anastomotic leakage after pancreaticoduodenectomy earlier than current standard of care.

Tissue oxygen saturation monitoring was a useful indicator of blood flow insufficiency in the gastric tube leading to anastomotic leakage during radical esophagectomy.

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.

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.

The TENTACLE: Rectum study is a multinational retrospective cohort study that includes patients with anastomotic leakage after rectal cancer resection. The study aims to develop an anastomotic leakage severity score and to evaluate the efficacy of different treatments of anastomotic leakage.

The peripheral perfusion index (PPI) is a non-invasive, feasible measure of peripheral perfusion and, assumed, the overall circulation, which all patients are monitored by. This study is carried out to assess the association between values of PPI, haemoglobin and blood transfusion. Hypothetically, patients with low values of hb are more susceptible to a deteriorating circulation reflected in poorer PPI regardless of blood pressure and that resuscitation with blood products improves PPI measurements. Moreover, that patients with low values of PPI have more surgical complications and higher mortality.

In our previous study, a nomogram model was established to predict intra-abdominal infectious complications after gastrointestinal surgery. This model was based on the clinical data and the drainage fluid cytokine levels, and it received an AUC >0.9. In this study, validation of this nomogram is planned to be conducted in this prospective cohort study.

This study will assess the effectiveness of commercially available LifeSeal® Kit as measured by the incidence of post-operative clinical anastomotic leak rates in subjects undergoing low and ultralow anterior resection with an anastomosis. All patients treated with LifeSeal® will be offered to participate

Prospective evaluation of early diagnosis of anastomotic leak after colorectal resection through evaluation of Dutch leakage score, serum C-reactive protein and serum Procalcitonin

Prospective observational multicenter study on the influence of adherence to enhanced recovery pathways on early outcomes (anastomotic leakage, morbidity, mortality, readmission, reoperation rates and length of postoperative stay) after elective colorectal surgery in Italy.
