The Impact of 3D Patch One-Suture Fixation vs No Fixation on Chronic Pain and Recurrence in Ⅲ Inguinal Hernia

This study aims to compare the effects of one-stitch fixation and non-fixation of 3D patches on chronic pain and recurrence in type III inguinal hernia. The primary outcome measures include hernia recurrence, chronic pain, etc.

Image-Guided Herniorrhaphy Study

This pilot clinical study will evaluate the safety and effectiveness of a new image-guided, needle-based approach for repairing abdominal or groin hernias in adults who are unable or unwilling to undergo traditional open or laparoscopic surgery. The technique uses ultrasound and, when needed, CT imaging to guide a hollow needle preloaded with barbed suture through the skin to close the hernia defect without large incisions or general anesthesia. Each participant will undergo one image-guided procedure and will be followed for eight months to assess complications and changes in hernia-related quality of life. Approximately thirty participants will be enrolled. The study aims to determine whether this minimally invasive approach is safe, feasible, and capable of improving hernia symptoms enough to justify a larger clinical trial

Pneumoperitoneum Duration and Bicarbonate Changes in Laparoscopic Hernia Surgery

The goal of this observational study is to learn how the length of pneumoperitoneum during laparoscopic inguinal hernia surgery may affect changes in blood bicarbonate levels. Pneumoperitoneum is the use of carbon dioxide gas to create space inside the abdomen during laparoscopic surgery. The main question this study aims to answer is whether a longer pneumoperitoneum time is associated with changes in blood bicarbonate levels after surgery. Participants are adults undergoing laparoscopic inguinal hernia repair as part of their routine medical care. Researchers will measure blood gas values, including bicarbonate levels, before surgery and again two hours after surgery. The change in bicarbonate levels will be compared with the duration of pneumoperitoneum during the operation. The results of this study may help improve the understanding of metabolic changes that occur during laparoscopic surgery.

Feasibility Study of Non-Contact Imaging-Based Physiological Monitoring in the Operating Room

This study aims to evaluate the feasibility and accuracy of a non-contact, camera-based physiological monitoring technology in a perioperative setting (including anesthesia induction, surgery, and recovery).Conventional vital sign monitoring tools-such as ECG leads, blood pressure cuffs, and pulse oximeters-require direct skin contact, which may pose risks of cross-infection or skin injury in vulnerable populations (e.g., newborns or elderly patients). This research utilizes remote Photoplethysmography (rPPG) technology to estimate vital signs, including heart rate, blood pressure, and blood oxygen saturation (SpO2), by analyzing facial video captured via standard camera devices (Logitech C930, iPhone 16 Pro Max, and Samsung Galaxy S24 Ultra).The primary goal is to assess the consistency and stability of this non-contact system compared to clinical gold-standard monitors (Masimo Root, SedLine O3, and Radical-7) during actual surgical procedures. The findings will serve as a foundation for developing non-invasive, supplementary monitoring tools in dynamic clinical environments.

No Opioids vs. Minimal Opioids Following Inguinal Hernia Repair

The investigators hypothesize that not prescribing opioids after uncomplicated, outpatient IHR will be non-inferior to prescribing opioids (5 tablets of Oxycodone, 5mg; or surgeon preference for intolerance) with respect to requests for opioid refills. Additionally, the investigators believe there will be no significant difference in postoperative readmission for pain quality of life at 30 days in either group.

Natural History of Infants With Patent Processus Vaginalis

This will be a multi-center prospective observational study of all patients who undergo laparoscopic pyloromyotomy. Subjects who have PPV will be followed up to just before their 18th birthday through annual phone calls or emails to determine the incidence and timing of subsequent inguinal hernia.

PRO-RSTAP: Effect of TAP and RS Blocks on Recovery After Inguinal Hernia Surgery (PRO-RSTAP)

Inguinal hernia repair is a common surgical procedure, often performed as day-case surgery. Despite standardized surgical techniques, postoperative pain may delay recovery and occasionally lead to unplanned hospital admission. The PRO-RSTAP study is a prospective, randomized, double-blind clinical trial evaluating whether ultrasound-guided transversus abdominis plane (TAP) block, rectus sheath (RS) block, or their combination improves postoperative recovery after open inguinal hernia surgery. Adult patients undergoing unilateral open inguinal hernia repair are randomized into four groups receiving either combined TAP and RS blocks, TAP block only, RS block only, or placebo blocks , in addition to standard perioperative care. The primary outcome is total perioperative opioid consumption measured as intravenous morphine equivalents. Secondary outcomes include postoperative pain scores, need for rescue analgesia, postoperative nausea and vomiting, time to discharge, unplanned hospital admission, and chronic postoperative pain during long-term follow-up. The aim of this study is to determine the individual and combined effects of TAP and RS blocks on postoperative analgesia and recovery in patients undergoing open inguinal hernia repair.

Treatment of Occult Inguinal Hernias

Inguinal hernias are a common surgical problem. Best management of occult inguinal hernias, defined as hernias unable to be felt on physical exam, is unknown. From prior studies we know that most inguinal hernias will eventually become symptomatic and require surgery (70%). However, doing a repair on a very small, occult hernia may open the patient up to surgical complications, like chronic pain, earlier than necessary. This will be a multi-center randomized controlled trial of surgical repair versus expectant management of occult inguinal hernias. Patients undergoing laparoscopic unilateral inguinal hernia repair will be included. At the time of surgery, the surgeon will determine if there is an occult hernia contralateral side. If present, patients will be randomized to repair of the occult side or expectant management of the occult side. After 1 year post-operative data has been assessed, a decision tool will be created and administered to patients to aid in their decision making about treatments for their hernia.

Prevention of Surgical Site Infection in Open Paediatric Groin Surgeries Using Intravenous Prophylactic Antibiotics and Antimicrobial-coated Sutures

The goal of this clinical trial is to learn if the use of prophylactic antibiotics and antimicrobial-coated sutures can prevent surgical site infection in children undergoing open groin surgeries. The main question it aims to answer is: • Does the use of intravenous prophylactic antibiotics or antimicrobial-coated sutures significantly reduce the occurrence of surgical site infection in children undergoing open groin surgeries? Researchers will compare no antibiotic use to the use of intravenous prophylactic antibiotics, or antimicrobial-coated sutures to see if the use of intravenous prophylactic antibiotics and antimicrobial-coated sutures significantly reduces the occurrence of surgical site infection following open groin surgeries in children. Participants will: * Undergo open groin surgery with either the use of intravenous prophylactic antibiotic or antimicrobial-coated sutures or without antibiotic use * Visit the clinic on postoperative days 5, 13 and 30 for review of the surgical wounds for any sign of infection.

Swing-Mesh™ Study (SMS).

This multicenter, prospective observational study aims to assess the safety and efficacy of the Swing-Mesh™ implant (THT BioScience™, distributed by B. Braun™, France) for laparoscopic-endoscopic inguinal hernia repair using TAPP or TEP techniques. Swing-Mesh™ is a lightweight, macroporous, three-dimensional mesh designed to conform anatomically to the myopectineal orifice without requiring fixation. Eligible adult patients undergoing elective repair will receive the implant. The primary endpoint is hernia recurrence within 6 months. Secondary endpoints include postoperative pain, groin discomfort, and early and late complications. The study will provide clinical evidence regarding the non-inferiority of this spatial, fixation-free mesh compared to standard devices in minimally invasive hernia surgery.

Post-operative Pain Control-TAP Block Using Exparel vs. Marcaine for Hernia Repairs

While studies have shown improved postoperative pain control with TAP blocks after inguinal and ventral hernia repair, data comparing Liposomal bupivacaine (Exparel) to bupivacaine alone in formulation of the TAP block is particularly scarce. Therefore, we designed a prospective, randomized trial comparing the postoperative pain control in minimally invasive ventral and inguinal hernia repair patients who receive an Exaparel-based TAP block compared to the traditional bupivacaine (Marcaine) TAP block.

Methocarbamol in Ventral and Inguinal HR

The purpose of this study is to gather information on methocarbamol as a pain management treatment for ventral or inguinal hernia repair. Methocarbamol has been part of the pain management treatment for both inpatient and outpatient procedures at Prisma Health. This study will compare the outcomes of patients who receive methocarbamol, those who receive the standard opioid pain management treatment, and those who receive methocarbamol plus the standard opioid pain management treatment. Participants will be randomized into one of the study groups listed below. Primary ventral hernia repair or inguinal hernia repair: Group 1: standard opioid after surgery Group 2: methocarbamol after surgery Open or robotic ventral hernia repair outpatient: Group 1: standard opioid after surgery Group 2: standard opioid plus methocarbamol after surgery Open or robotic ventral hernia repair inpatient: Group 1: standard opioid at discharge Group 2: standard opioid plus methocarbamol at discharge A total of 200 participants will be included in the study. Participation will last for about 30 days after surgery.

Effects of Virtual Glasses, Stress Ball and Music Intervention on Pain, Anxiety and Comfort in Patients Undergoing Inguinal Hernia Surgery

Although it changes with age, due to its high incidence and prevalence, inguinal hernia is one of the most commonly performed surgeries by general surgeons. Pain, anxiety and changes in comfort levels in patients after inguinal hernia repair surgery negatively affect the patient's recovery after surgery. One of the goals of nursing care practices in the perioperative period, especially in patients undergoing surgery, is to provide and maintain patient comfort. Today, the concept of comfort is a part of quality nursing care, allowing patients to be comfortable, carefree, recover more quickly and cope better with disease stress. Using non-pharmacological methods in pain management reduces the use of pharmacological methods, increases the patient's comfort level, reduces stress and anxiety, increases the individual's sense of control over their own health and increases physical function and daily life activities. Virtual reality, music therapy, stress ball are used in various areas of clinical medical care as a way to distract attention and relieve pain.
