Active clinical trials for "Hernia, Ventral"

The goal of this randomized controlled trial is to compare preoperative intensive weight management to upfront surgery in obese patients undergoing complex abdominal wall reconstruction. The main question is will abdominal wall specific quality of life (using the HerQLes survey) for the group undergoing upfront surgery be non-inferior compared to the group in the weight management program.

The purpose of this protocol is to determine the safety and efficacy of abdominal wall transplantation as a treatment for the reconstruction of abdominal wall defects. Abdominal wall transplantation may be performed alone or in combination with another transplant.

This study evaluates effect of anterior component separation and posterior component separation and transversus abdominis muscle release methods for treatment of midline ventral hernias.

In this randomized clinical trial, the investigators will compare the conventional open repair for hernia in the anterior abdominal wall with the robotic-assisted approach. 110 patients with midline abdominal wall defects will be randomized to either open or robotic-assisted surgery. The investigators will examine short and long-term complications through follow-up with clinical assessment as well as patient-reported outcome measures including pain, cosmetic appearance, and overall patient satisfaction. Furthermore, the investigators will study the difference in surgical stress response between the two methods measured from a variety of different biomarkers before and after the operation. A cost-effective analysis will be conducted for the robotic and open procedure.

The primary objective of the study is to demonstrate that hernia recurrence (VH) repair with non absorbable mesh concomitant to Bariatric Surgery (BS) decreases the risk of VH, with or without surgical repair, during the first two years after BS when compared to VH suture repair without mesh. As secondary objectives, the study aims to assess the impact of concomitant VH repair with non absorbable mesh versus suture repair in morbidly obese BS candidates on the following measures: - hernia recurrence at 1 year after randomization; - reoperation for hernia recurrence at 2 years after randomization; - strangulated hernia, surgical infection and mesh bulging at one year after randomization; - postoperative morbidity and mortality at 90 days after randomization; - benefit-risk ratio; - chronic pain at three months, six months, one year and two years after randomization; - quality of life during the two years after randomization; - incremental cost utility ratio; - short- and mid-term weight loss. To study if the efficacy of mesh versus suture VH repair differs according to the type and size of VH and to the surgical technique.

The goal of our work of optimization of the treatment of postoperative hernias is to improve the results of treatment of patients with median and median-lateral postoperative hernias of medium (W2) and large (W3) sizes by developing new surgical techniques. The main questions it aims to answer are: To study the topographic and variant anatomy of vessels and nerves in the retromuscular, preperitoneal, postperitoneal and pre-abdominal cell spaces of the anterior abdominal wall. To determine the most probable sources of blood flow and lymph from the anatomical formations forming the bed of the endoprosthesis. To develop technical, surgical techniques that allow to form an implant bed with minimal traumatization of blood vessels and nerves and reduce the risk of postoperative complications. To develop a technique for plasty of the anterior abdominal wall in mid-lateral postoperative hernias with a combination of retromuscular and subaponeurotic spaces. The researchers will compare an experimental group in which a new method of preparing the implant place will be used and a control group in which standard methods of treating postoperative ventral hernias were used to see whether the new method affects the improvement of the postoperative period and the reduction of complications.

The investigators are testing the ability of vacuum dressings to improve wound healing for patients having large hernias surgically repaired who are at risk of having wound complications. The trial will randomly be giving some patients having this surgery the vacuum dressing and some a standard dressing and observing how their wounds heal in hospital and at follow-up appointments.

Ventral hernia repair is associated with significant postoperative pain, and regional anesthetic techniques are of potential benefit. The postoperative mobility and training is of utmost importance in this patient group, and could be increased using local anesthetics instead of opioids. Inadequate post-operative pain control can lead to adverse consequences for patients, such as the development of chronic pain, immunosuppression, poorer healing of surgical wounds, as well as adrenergic activation and its consequences in the form of coronary incidents or gastrointestinal obstruction and postoperative nausea and vomiting (PONV). Moreover, lack of mobility can result in thrombosis and embolism. These complications affect hospital functioning, which leads to decreased patient satisfaction, a worse reputation for the hospital, longer stays in the recovery room, prolonged hospitalizations, higher incidence of re-surgeries and re-admissions, and higher costs for care and treatment. Erector spinae plane block (ESPB) is the latest of the truncal blocks and was first described in 2016. The efficacy of bilateral ESPB at the T7 level has been described in a study of 4 cases, moreover effective analgesia with ESPB after bariatric surgery has been described in a study of 3 cases. When performed at the level of the T7 transverse process, studies show the potential to block both supra-umbilical and infra-umbilical dermatomes. So far there are mostly case studies done in this field of study, and internationally there is a call for research into the effect of this technique and randomized controlled trials. The objective of this study is to compare ESPB to multimodal analgesia in patients undergoing ventral hernia repair.

The purpose of this study is to determine whether a program to optimize patient physical fitness and nutrition ("prehabilitation") prior to and after plastic surgery involving the abdomen improves surgical outcomes. The investigators hope to determine how a multimodal peri-operative prehabilitation program can be most effective in engaging and motivating patients to physically and mentally get ready for an abdominally-based plastic surgery operation. The overall goal is to determine if this program will improve post-operative recovery after abdominally-based plastic surgery. The importance of this new knowledge is better understanding of ways that plastic surgeons can improve outcomes, engagement, and experience of patients undergoing abdominally-based plastic surgery operations. This would translate to increased healthcare value and better long-term outcomes.

Study includes 5 visits: Screening, Baseline/Surgery, and 14 days, 3 months, 12months Follow-Ups post-surgery. The actual point of enrollment for each subject is considered the day of surgery. Total study duration is up to 12 months post-surgery. Surgery will be performed under general anesthesia. Standard antibiotic prophylaxis will be administered 30 min prior to skin incision. A surgical assistant will be selected by the PI from the surgical staff of the department. The procedure will involve placement of laparoscopic ports, reduction of the hernia sac, closure of the defect with the Su2ura® approximation device and fixation of mesh with tacks over the closed defect in an IPOM fashion. Based on surgeon consideration, primary umbilical hernia defects under 2 cm will be repaired with or without mesh. Study follow-up visits will take place 14 days, 3 months and 12 months post-surgery.
