Umbilical Hernia

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.

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.

The study attempts to quantify the relative risks for acute postoperative pain, complications rate, chronic postoperative pain (CPIP) and recurrence rate after different methods of repair of groin, umbilical and incisional hernia depending on surgical technique, mesh type and fixation suture material. For this purpose the investigators will analyze data from the Kalinigrad Hernia Registry (KHR).
