Active clinical trials for "Anastomotic Leak"

NERv's early feasibility clinical trial is a first-in-human, multi-center, pre-market, non-randomized clinical trial intended to evaluate the safety and collect preliminary data necessary for the detection of clinical post-operative anastomotic/intraperitoneal leakages. NERv's Inline Device attaches to existing catheters or peritoneal drains that are currently being used in the medical industry. This allows the device to measure the pH and conductance of intraperitoneal fluids that typically get drained through peritoneal drains. The purpose of NERv's feasibility clinical trial is to collect pH and conductance readings by analyzing peritoneal drainage fluid. Upon analyzing data collected from NERv's Inline Device a clinical model of pH and conductance will be created. The clinical model can then be used to determine if a complication is developing. For instance, boundaries (reading thresholds) can be established where if the signal goes outside the boundaries a complication could be identified. Specifically the ability to detect a post-operative complication known as anastomotic leakage; which is a dreaded complication associated with abdominal surgeries; will be the main focus of the study.

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.

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.

LifeSeal™ Kit, surgical sealant designed for staple-line reinforcement that is applied over the anastomotic line to prevent bowel content leakage until full physiological function is restored. RATIONALE : Postoperative anastomotic leakage is one of the most devastating and feared complications in colorectal surgery. The risk of postoperative anastomotic leakage varies widely depending on the level of anastomosis while the risk is higher in low anastomosis. In order to best demonstrate the benefits of LifeSeal™ in providing staple line reinforcement and helping to reduce leaks, the study includes high risk anastomoses, defined as colorectal and coloanal anastomoses performed within 10 cm from the anal verge. STUDY DESIGN: This study is designed as a prospective, multi-center, multinational randomized, single-blind, double armed study PRIMARY OBJECTIVE: The primary objective of this study is to assess the efficacy and safety of LifeSeal™ Kit as measured by the change in overall anastomotic leak rates in subjects undergoing low anterior resection with an anastomosis below 10 cm from the anal verge, over the first 17 weeks after surgery. SECONDARY OBJECTIVES: The secondary objective of this study is to assess the incidence of post-operative leaks and additional benefits that could be related to the use of LifeSeal™ Kit such as reducing the severity and improving the outcome of a leak once it has occurred. In addition, the study will allow for collection and analysis of additional safety data and usability assessment of the device, medical resource utilization, and health related quality of life measures.

Patients with suspected leakage at the specified surgical anastomoses undergo an immediate diagnostic endoscopy as part of current clinical routine. Consenting patients meeting the inclusion criteria will undergo closure of the defect by endoscopic suturing in addition to standard surgical care.

This trial aims to assess safety and efficacy of three-row circular staplers compared to two-row surgical stapllers in short-term and long-term perspective in patients with rectal cancer undergoing low anterior resection with stapled colorectal anastomosis. All the patients will undergo a low anterior resection. In a half of patients a colorectal anastomosis will be created with a three-row surgical circular stapler. In another half of patients a colorectal anastomosis will be created with a two-row surgical circular stapler.

The purpose of this study is to determine the short and long term outcome of endoscopic vacuum assisted closure of intrathoracic postsurgical leaks.

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.

Anastomotic leakage is a major and potentially mortal complication with an incidence of 10-13% after resection of the rectum. For patients showing no clinical signs of peritonitis, the traditional method has been a conservative treatment with transrectal rinsing. This treatment is often associated with a very protracted postoperative course with healing times of up to a year or more for the anastomotic leakage. Treatment with vacuum drainage (VD) is a new method primarily developed for wound therapy. The objective of this study is to investigate the effects of transrectal vacuum treatment on the healing of anastomotic leakage after rectum resection in a prospective, randomized, controlled multicentre trial in 60 patients found to develop clinically significant anastomotic leakages after elective rectal resection.

Anastomotic dehiscence is the most feared complication in colorectal surgery, occurring in 6.3% -13.7% in patients with pelvic anastomoses [1-4]. This complication significantly increases morbidity, mortality, costs, and generates a greater impact on quality of life. In addition, several studies point to an increased risk of locoregional recurrence [5, 6]. There are different risk factors for anastomotic dehiscence: some preoperative, such as malnutrition or obesity [9]; other intraoperative ones, such as hypoperfusion of the anastomotic tissue or the anastomotic technique; and others postoperative, such as some types of medication [7]. In colorectal anastomoses, there is some concern about the safety of the double stapling technique, since the extremes of the linear suture line (called "dog ears") and the number of staple lines have a direct relationship with the risk of dehiscence [8-11]. With the aim of reducing suture dehiscence rates, different intraoperative techniques have been developed, such as reinforcing the anastomosis with stitches, the use of indocyanine green [12, 13] or the application of anastomotic sealants [14], without finding a definitive solution. Recently, benefits have been published of using the double-staple colorectal anastomosis lateral invagination technique, with the aim of avoiding "dog ears" [15-17]. Several case series and retrospective comparative studies have shown a significant decrease in anastomotic dehiscence using this technique, with all the clinical and economic benefits that this entails [15-17]. In this sense, the present study aims to evaluate the effectiveness and safety of the lateral invagination technique of double-staple colorectal anastomosis in a randomized and controlled trial.
