Background/purpose: Lichtenstein mesh repair is the most common procedure used by surgeons for management of inguinal hernia due to its low recurrence rate and complications. However, post-operative complications like chronic groin pain, foreign body sensation, loss of sensation obtained a great attention. Successful inguinal hernia repair measured by minimizing the post-operative complication and maximizing the patient satisfaction. Guttadauro et al. described a new open repair procedure called All In One technique for management of primary inguinal hernia in adult to decrease the incidence of chronic post-operative pain and foreign body sensation, leading to improving patient‟s comfort [1].The objectives of this study To conduct a comparative study between the All In One technique and the Lichtenstein technique in order to evaluate the advantages and complications of each for treatment of inguinal hernia. Methods: This study was carried on 60 patients with primary inguinal hernia in the department of General Surgery, Zagazig University Hospitals during the period from August 2017 to January 2019.The patients divided into two groups : Group (A): was treated with All In One technique. Group (B): was treated with Lichtenstein technique. Results: the age of the studied patients in group (A) ranging from 22-70 years old with mean 46.26±13.22 and in group (B) ranging from 31-70 years old with mean 48.9±11.95 and most of the studied patients are in the 4th & 5th decade. All In One technique has significantly less loss of sensation over the groin, groin pain at 1,3,6 monthes and foreign body sensation over the groin . there is no significant difference in both groups as regard types of hernia ,operative time,Post-operative complications, Return to normal activity and Recurrence rate. Conclusions: the All In One technique procedure is considered as a good approach for the surgical treatment of primary inguinal hernia with less post-operative complications and less postoperative neuralgia, chronic groin pain, sensation of foreign body and loss of sensation with better patient compliance and satisfaction. It helps the less experienced surgeon to avoid pitfalls in dealing with nerves. Copy Right, IJAR
