Effect of Preoperative Erector Spinae Plane Block on Recovery Quality, Time to Return to Daily Activities, and Postoperative Pain Scores in Inguinal Hernia Surgery

This study aims to evaluate the effect of the erector spinae plane block (ESPB), performed after surgery, on quality of recovery, postoperative pain, and time to return to daily activities in patients undergoing open inguinal hernia repair under spinal anesthesia. Postoperative pain following inguinal hernia surgery may delay recovery and negatively affect patients' return to normal daily life. Although ESPB has been widely used as an effective analgesic technique in various surgical procedures, its effectiveness in inguinal hernia repair remains limited and not well established. In this randomized controlled study, patients will be divided into two groups: one group will receive ESPB after surgery, while the control group will not receive any block. All patients will receive standard postoperative analgesia. Quality of recovery, acute pain scores, and analgesic consumption will be assessed within the first 24 hours after surgery, and return to daily activities will be evaluated 30 days after surgery. The primary outcome of this study is quality of recovery assessed using the Quality of Recovery-15 (QoR-15) questionnaire. QoR-15 scores range from 0 to 150, with higher scores indicating better recovery. Scores will be recorded preoperatively and 24 hours after surgery. Secondary outcomes include postoperative pain intensity, total opioid consumption, and time to return to daily activities. Pain intensity will be assessed using the Numeric Rating Scale (NRS), where 0 indicates no pain and 10 indicates the worst pain imaginable, at 15, 30, 60, and 120 minutes, as well as 6, 12, and 24 hours after surgery. Total opioid consumption will be determined by recording the cumulative dose of intravenous tramadol administered as rescue analgesia within the first 24 hours after surgery. Time to return to daily activities will be evaluated via telephone follow-up 30 days after surgery.

Watchful Waiting Versus Immediate Repair for Occult Contralateral Inguinal Hernias.

This study will compare two ways of managing a small, hidden hernia that can sometimes be found during minimally invasive surgery to repair a hernia on one side of the groin. Occasionally while fixing the known hernia, the surgeon discovers a small hernia on the other side that has not caused any symptoms. Surgeons do not agree on the best way to handle these hernias. Some believe it should be repaired right away during the same operation to prevent it from getting bigger or from causing symptoms later, which could require another surgery. Others believe it is better to leave it alone since it is not causing problems and groin hernia surgery carries risks including long-term pain. This study will randomly assign patients, if a hidden hernia is found during surgery, to either having it repaired immediately or to have it monitored over time. Patients will be followed up at 30 days, 1 year and 2 years following surgery. The researchers will compare recovery and quality of life between the two groups. For those in the monitoring group, the study will also track whether the hidden hernia causes symptoms or eventually needs surgery. The goal is to determine whether repairing the hidden hernia right away is as safe and effective as watching and waiting, so doctors and patients can make more informed decisions in the future.

Postoperative Ozonated Oil Dressing After Open Inguinal Hernia Repair: A Randomized Pilot Trial

This study looks at whether a special wound dressing containing ozonated oil can reduce early wound inflammation after open inguinal hernia surgery. Open inguinal hernia repair is a common operation, and although infection rates are low, many patients experience redness, swelling, tenderness, or discomfort at the surgical site during the first days after surgery. Participants undergoing elective open inguinal hernia repair will be randomly assigned to receive either an ozonated oil-impregnated dressing or a standard sterile dressing after the operation. The main outcome is the level of wound inflammation measured on the third day after surgery. Other outcomes include wound temperature, pain levels, cosmetic healing, and wound-related problems during the first 30 days. The ozonated oil used in this study is a CE-certified medical product that is already used in routine wound care. This pilot study aims to provide preliminary data to help determine whether ozonated oil dressing may improve early wound healing compared with standard care.

Transversalis Fascia Plane Block Versus Surgical Wound Infiltration for Postoperative Analgesia in Open Inguinal Hernia Repair

The purpose of this clinical trial is to evaluate whether two different analgesic techniques - ultrasound-guided Transversalis Fascia Plane Block (TFPB) and surgical wound infiltration - can improve postoperative pain control in adult patients undergoing open inguinal hernia repair. The key questions that this study aims to answer are: Does TFPB reduce total intravenous opioid consumption within the first 24 postoperative hours compared with wound infiltration? Does TFPB improve postoperative pain scores at rest and during movement compared with wound infiltration? Does TFPB improve patient satisfaction, reduce the need for rescue analgesics, and enhance overall postoperative recovery quality? If there is a comparison group: The investigators will compare the effects of TFPB with wound infiltration to determine whether either technique provides superior postoperative analgesia and reduces opioid requirements. Participants will be asked to: Undergo open inguinal hernia repair under spinal anesthesia. Be randomly assigned to one of two groups: TFPB Group: Receive an ultrasound-guided transversalis fascia plane block with local anesthetic. Wound Infiltration Group: Receive local anesthetic infiltration performed by the surgeon along the incision line. Postoperatively: Report pain scores at defined intervals. Receive standardized IV analgesia with documentation of opioid consumption. Allow assessment of rescue analgesic requirement. Be monitored for adverse events and recovery outcomes.

Comparison the Analgesic Efficacy of Ultrasonographic Bilateral TAP and Anesthetic Infiltration Into the Surgery Field for Laparoscopic Unilateral TEP Herniorrhaphy

Laparoscopic inguinal hernia repair is a common surgical procedure, but postoperative pain management remains a challenge. This prospective, randomized study aims to compare the analgesic efficacy of preperitoneal and surgical site anesthetic infiltration with ultrasound-guided bilateral transversus abdominis plane (TAP) block in patients undergoing laparoscopic unilateral total extraperitoneal (TEP) herniorrhaphy. Sixty patients will be randomly allocated into two groups: Group-I will receive preperitoneal and surgical site infiltration with bupivacaine, while Group-II will receive ultrasound-guided bilateral TAP block with bupivacaine. The primary outcomes will be postoperative pain scores assessed using the visual analog scale (VAS) and additional analgesic requirements. Secondary outcomes will include postoperative hospital stay duration and cost-effectiveness. Demographic data, ASA scores, comorbidities, and operation times will be recorded. Postoperative pain will be managed with a multimodal approach, including paracetamol and NSAIDs. Rescue analgesia will be provided with intravenous paracetamol. Statistical analysis will be performed using t-tests, ANOVA, Wilcoxon-Mann-Whitney tests, and chi-square tests, as appropriate. This study aims to determine the optimal and most beneficial method for postoperative pain management and patient comfort following laparoscopic inguinal hernia repair.

Desarda Tissue Technique vs Lichtenstein Technique for Primary Inguinal Hernia Repair

This study aims to evaluate whether a surgical technique (Desarda) is superior to the commonly used surgical technique (Lichtenstein) in inguinal hernia repair concerning the occurrence of postoperative complications. The Lichtenstein technique involves the use of a mesh, while the Desarda technique does not.
