The goal of this clinical trial is to investigate whether mesh-suture affects wound complication rates, patient-reported quality of life, and operation time in adult patients undergoing surgery for small ventral hernias. The main questions it aims to answer are: Does mesh-suture reduce wound complication rates compared to planar mesh? Does mesh-suture improve patient-reported quality of life(QoL) and affect operation time compared to planar mesh? Comparison group: Researchers will compare standard treatment with planar mesh to the interventional treatment with mesh-suture to see whether mesh-suture leads to fewer complications, better quality of life, and shorter operation time. Participants will: Be randomized to receive either planar mesh or mesh-suture during hernia repair surgery. Undergo standardized preoperative assessment, including baseline data and QoL scoring. Attend a postoperative visit on day 7-13 for wound inspection and ultrasound. Complete QoL assessments at 90 days (telephone follow-up). Have operation time recorded and medical records reviewed for readmissions within 90 days.
NCT07327463
This observational study aims to compare the postoperative analgesic effectiveness of ultrasound-guided transversus abdominis plane (TAP) block and single-dose epidural anesthesia in patients undergoing umbilical hernia surgery. Pain intensity will be assessed using the Visual Analog Scale (VAS) at predefined postoperative time points. The study seeks to determine which analgesic approach provides superior pain control and patient satisfaction in the postoperative period.
NCT07367321
Umbilical hernia is a common condition that is frequently treated with surgical mesh repair to reduce recurrence rates. Among the commonly used techniques, onlay mesh repair and sublay mesh repair are widely performed; however, there is ongoing debate regarding their comparative effectiveness and safety. The aim of this study is to compare onlay mesh repair and sublay mesh repair in patients undergoing elective umbilical hernia surgery, with respect to postoperative complications, recurrence rates, operative outcomes, and length of hospital stay. By evaluating clinical outcomes associated with each technique, this study seeks to contribute evidence to guide the selection of the most appropriate surgical approach for umbilical hernia repair.
NCT07324863
This study aims to evaluate the efficacy of ultrasound-guided external oblique and rectus abdominis plane block on the neuroendocrine stress response and postoperative analgesia in adults undergoing umbilical hernia repair.
NCT06522308
Researchers aim to determine the exact prevalence and risk factors for the association of gallstones and umbilical hernia. Umbilical hernia is defined according to the European Hernia Society Classification for primary and incisional abdominal wall hernias as hernias occurring from 3 cm above to 3 cm below the umbilicus. The main outcome measures are the presence of gallstones in patients presenting with umbilical hernia and the presence of umbilical hernia in patients diagnosed with gallstones. Patients with umbilical hernia are examined with biliary ultrasound, while patients with cholelithiasis are evaluated for umbilical hernia by physical examination and ultrasound. Factors such as age, gender, body mass index (BMI), family history, comorbidities, tobacco use, parity, and history of multiple pregnancy are analyzed as potential risk factors.
NCT06412406
AIM OF STUDY: Comparison between effect of external oblique intercostal plane block and the Oblique subcostal transversus abdominis plane block in paraumbilical hernia repair as analgesia for intraoperative and postoperative pain.
NCT04231071
Umbilical hernia repair is one of the most common surgical performance in general surgery. Up to now, the use of suture repair has been the preferred technique for small umbilical hernia defects without any gold standard procedure. Mesh have been reserved to larger umbilical hernia defects. However, there is an increasing evidence that mesh reinforcement could be advantageous to lower the high recurrence rates also in smaller umbilical hernias. A remained important question is in what anatomical position the mesh should be placed. The investigators hypothesize that the use of an onlay mesh in small umbilical hernia defects can reduces recurrence rates without increasing postoperative complications compared to a suture repair.
NCT05576753
The aim of this study is to measure the mesh shrinkage and the visualization of the mesh with MRI scan at 1 month and 13 months after robot assisted preperitoneal hernia repair using the visible CICAT mesh (Dynamesh®).

Ventral hernias can be repaired using a variety of techniques, with smaller defects often being amenable to minimally invasive surgical (MIS) approaches. For many years, the standard of care MIS approach to ventral hernias has been the laparoscopic intraperitoneal onlay mesh (IPOM) approach, in which a large piece of mesh is placed inside of the abdomen and fixed to the inner abdominal wall using a combination of sutures and/or mechanical tacks. For selected patients, the IPOM approach has demonstrated benefits over open repair, including decreased postoperative length of stay and decreased incidence of surgical site infection. However, concern regarding long-term outcomes of placing mesh inside the abdomen have spurred the search for alternate approaches to MIS ventral hernia repair. This includes the enhanced-view totally extraperitoneal (eTEP) approach, in which the retromuscular plane is accessed and developed so a large piece of mesh may be implanted outside of the abdominal cavity. The theoretical benefits of this approach are that patients may experience reduced pain because mechanical mesh fixation is not required (as compared to traditional IPOM approaches in which mesh is fixed to the inner abdominal wall) and that mesh is kept outside of the abdominal cavity and away from the viscera, allowing use of less expensive, uncoated mesh and theoretically reducing risk for long-term mesh related complications. While popularity of eTEP has grown, literature published regarding this approach has been mostly retrospective, consists of relatively small series of patients, and suffers from selection bias. For the one prospective study of eTEP published by Radu, et al, there was no comparator arm. The investigators will conduct a registry-based randomized controlled trial comparing MIS approaches for repair of small to medium-sized ventral hernias, specifically eTEP versus IPOM. This will occur through the Americas Hernia Society Quality Collaborative (AHSQC). Our hypotheses are multiple: 1) Patients with ventral hernias undergoing eTEP will experience a 30% decrease in pain scores by postoperative day 1 compared to patients undergoing IPOM; 2) eTEP will be associated with higher median direct costs per case versus IPOM; 3) eTEP will be associated with equivalent 1-year hernia recurrence rates versus IPOM; 4) eTEP will be associated with significantly increased intraoperative surgeon workload compared to IPOM.

The aim of this study is to compare immediate and long-term (24 months) results of laparoscopic and open mesh repair of incisional and umbilical hernia.
NCT04687579
Liver cirrhosis is a frequent and severe chronic disease. About 20 % of patients with liver cirrhosis develop umbilical hernias. In comparison, the prevalence in the general population is around 2 %. Patients with liver cirrhosis are often neglected and are not offered equal surgical treatments compared with other patient groups with chronic diseases due to fear of postoperative complications. The current literature is sparse, and many questions remain to be answered, such as timing of repair, risk profile, preoperative staging of the liver disease, possible optimization before surgery, repair technique, and postoperative care. Moreover, nationwide data are lacking. The management of umbilical hernias in patients with cirrhosis is debated. Recently, European Hernia Society published guidelines stating that elective hernia repair may be safe, and that emergency repair is associated with a high rate of morbidity and mortality. Nonetheless, surgeons remain reluctant to perform elective surgery on these patients due to fear of complications and mortality. The evidence supporting the guidelines is sparse and consists of small, low quality studies. One of the major concerns is that the existing studies failed to use clear and well-described definitions of the underlying severity of the liver disease. The rate of emergency repair may be much higher in patients with liver cirrhosis compared with the general population but there is no data available. The rate of emergency vs elective repair in patients with liver cirrhosis in Denmark is unknown, as well as the rate of reoperation for complications and readmission. Finally, we hypothesize that these patients may benefit from a more proactive approach with early diagnosis of their umbilical hernia by screening, preoperative optimization, and early elective hernia repair, but the effect of this hypothesis needs further evaluation.
NCT03200405
The purpose of this study is to determine the exact position of a mesh which is placed in underlay position in umbilical hernia in vitro. The investigators want to gain information if the mesh lays directly next to the abdominal wall fascia or if there´s fat tissue between mesh and fascia. Furthermore they hope to get some information about the tissue incorporation.
NCT01607801
background Operation for small umbilical hernias is one of the most common surgical procedures, but the best surgical technique, including the choice of suture or mesh remains unknown. It is well known that using non-absorbable sutures in closure of the abdomen, diminishes the risk of incisional hernias and wound healing problems.It has also been found that the use of resorbable suture in fixation of the mesh in Lichtesteins procedure leads to greater risk of recurrence of the hernia. Furthermore, it has been stated in smaller studies, that the use of the mesh in open operation for a small umbilical hernia has lower risk of recurrence (approx. 1-3%) than sutured repair (10-12 %). However, the scientific literature is deficient, with few patients. The purpose of this study is to describe reoperation rate of recurrence after small umbilical hernias, depending on choice of sutures in both regular repair and in mesh repair. Hypothesis: sutured repair with non-absorbable suture has lower recurrence rates than with other types of sutures, whereas mesh repair has even lower recurrence rates in small umbilical hernia repairs.

For small (2-3cm) ventral and umbilical hernias the discussion for primary suture repair or the use of mesh continues. About 5 years ago the Ventralex patch was introduced, which combines a layer of PTFE mesh with a small polypropylene mesh and includes a circular memory ring. Despite the elegance of using this patch, recent experience showed several drawbacks both in design and efficacy (3). With the recent development of the Proceed Ventral Patch (PVP), new elements have been introduced to overcome some of these issues. The aim of this study is to evaluate the efficacy of clinical placement of the PVP in the intra-abdominal position in the treatment of small ventral hernias.
