Properties of abdominal wall intraperitoneal implants were assessed in vivo on 76 rabbits. Implants of polytetrafluorethilene (PTFE), uncoated mesh polypropylene and polypropylene with one- and two-side collagen coat, oxycellulose and polyoxibutirate coated implants were compared. Animals were extracted from the experiment on 14, 90 and 210 days with further implant assessment. PTFE and collagen-coated prostheses showed the least number of adhesions. Retraction was 5-14%. Prosthetic integration into the abdominal wall varied. PTFE and collagen-coated polypropylene proved to be the most appropriate materials for intraperitonel mesh hernia plasty.

Transabdominal preperitoneal patch plasty (TAPP) versus total extraperitoneal patch plasty (TEP) are surgical techniques commonly used to treat inguinal hernia. However, studies indicate that both procedures may lead to significant complications, particularly gastrointestinal complications, some of which can be life-threatening. We statistically analyzed the complications caused by adult inguinal hernia patients admitted from 2018 to 2022.

Introduction: Hernia repair is a common procedure performed by general surgeons. Introduced in 1990s, the use of laparoscopic hernia repair has recently increased and, consequently, rare complications previously unknown have been reported.
Presentation Of Case: A 43-years-old male patient who underwent a transabdominal preperitoneal patch plasty (TAPP) procedure for symptomatic bilateral inguinal hernia.

Background: Formation of seroma/hematoma is one of the most common postoperative complications following laparoscopic inguinal hernia repair. This study aimed to identify risk factors associated with seroma/hematoma and construct a prediction model.
Methods: Elderly subjects undergoing laparoscopic Transabdominal preperitoneal Patch Plasty (TAPP) were included in this study.

Background: Inguinal hernia develops as one of the common complications after robotic or laparoscopic radical prostatectomy (RP). Transabdominal preperitoneal patch plasty (TAPP) for an inguinal hernia after RP is difficult to perform due to postoperative severe adhesions in the preperitoneal cavity. We have introduced a high peritoneal incision approach (HPIA) in TAPP for inguinal hernia patients in whom peritoneal dissection is difficult due to severe adhesions after RP.

Purpose: Risk of total extraperitoneal hernia repair (TEP) in patients with previous lower abdominal surgery (PLAS) is still debated. The present study was designed to assess the rate of conversion in TEP for inguinal hernia stratified by type of PLAS.
Methods: Variables on patients undergoing TEP inguinal hernia repair at our center were prospectively collected between July 2012 and May 2018.
