Active clinical trials for "Tissue Adhesions"

Several methods have been used to predict adhesions after abdominal operations. High-resolution ultrasonography, magnetic resonance imaging and scar healing properties were the methods that were evaluated in the English literature for this study. Estimating the likelihood of adhesions and related complications after prior surgery and assessing the severity of adhesion formation after surgery is not easy. Anticipating adhesions is very important to preventing complications by ensuring that the necessary preoperative preparations are in place and/or that appropriate cases are referred to a tertiary center.

The aim of this randomized controlled trial is to determine whether the use of barbed sutures to close uterine incision at cesarean section is associated with more postoperative adhesions compared with conventional sutures or not.

The primary objective of this study is to assess visual function in up to 44 patients who have previously participated in either of the placebo controlled, ocriplasmin Phase III studies (TG-MV-006 or TG-MV-007).

Our study aims to characterise a possible pluripotent cell population in the abdomen responsible for peritoneal adhesions. We therefore want to take samples from women undergoing planned laparoscopic surgery with and without adhesions, isolate the cells and characterise them for markers of pluripotency.

11-20% of patients undergoing abdominal surgery develop chronic abdominal pain. Adhesions are a common cause of chronic pain following surgery. Adhesions develop after up to 90% of laparotomies and 70% of laparoscopic surgeries. Obviously, not all adhesions cause pain. It is still poorly understood why adhesions cause pain in some patients, while other patients with adhesions experience no pain. In this study we explore possible mechanism through which adhesions might cause pain. For this purpose we will assess expression of molecular mediators (such as TRPV-1, SP, and the neurokinin receptor), histological characteristics, and fecal microbioma that might be associated with pain.Expression of these factor will be compared to sample from 30 patients with chronic pain attributed to adhesions, and 30 patients undergoing a reoperation with adhsiolysis for reasons unrelated to pain.

Recognition of intraabdominal adhesion before doing repeated cesarean section is helpful for the surgeon and patients.

This study aims to demonstrate the histological differences in the connective tissue surrounding laser-treated abutments and untreated abutments in humans. Working hypothesis: There are differences in the adhesion of collagen fibres around implant abutments with laser-produced microgrooves and standard abutments.

The rate of cesarean section deliveries has increased dramatically worldwide in the last decades. While the cesarean birth rate was 4.5% in the USA in 1965, it was 31.8% according to 2007 data and is thought to be over 50% at present. The reasons for this include advanced age of primigravida, a wide range of indications, patient requests, the frequency of women with previous cesareans, women's rejections to offers of sterilization, and the common usage of assisted reproductive techniques

Chronic abdominal pain is highly prevalent in patients undergoing abdominal surgery. Adhesions are reported to be one of the most common causes of chronic pain after surgery. There is little epidemiological data on the natural course and risk factors of pain. In this study the investigators will assess risk factors for chronic pain and natural course by tracking pain scores through an app in a cohort of 1,500 patients undergoing abdominal surgery. In part two of the study patients with persistent abdominal pain at 12 months, that meet IASP criteria for chronic pain will have clinical investigations to determine the cause of their pain. This investigation includes cineMRI for diagnosis and mapping of adhesions.

In this prospective, multicenter, large-scale study，the investigators wish to examine the accuracy of several three-dimensional ultrasound anatomical and vascular parameters in diagnosing IUA when compared to the gold standard of hysteroscopy，and to assess the value of 3D US applying in prognosis of intrauterine adhesions.
