Background: Hernia is an unusual bulging of the intra-abdominal viscera through a weak area of the abdominal wall or groin region. Inguinal hernia repair is one of the most frequently performed surgical procedures. In recent years, inguinal hernia (IH) repair was changed from pure tissue repair to prosthetic laparoscopic repair. Objective: we propose to find a new application for the well-known surgical open mesh inguinal hernia in the treatment of inguinal hernias in adults aiming to improve patients' comfort and to reduce the incidence of chronic neuralgia. Patients and Methods: . A comparative study was designed to study the outcome of different sizes of mesh used in the hernia operations. In the present study, patients diagnosed with primary unilateral inguinal hernia (n=130) were enrolled from May 2019 to March 2020 at Baquba teaching hospital in Diyala governorate. Enrolled patients were divided into two groups. Group A include patients who have inguinal hernia operated with all in one procedure (n=65) and group B included patients with inguinal hernia operated by the classical method (n=65). Spinal and general anaesthesia were used. Before incision for the patient, ceftriaxone (1gm, intravenously) was administrated over 30 min. The process was accomplished on a one-day surgery basis .According to the devised technique, a new smaller prosthesis was placed on the floor of the inguinal canal in order to strengthen all areas of weakness from which hernias may originate. The mesh was enveloped by a fibro-cremasterico sheath avoiding contact with neural structures. Follow-up was carried out at 1week, 1month, 3months for evaluation of postoperative pain using numbering scale score, need of medication, patients' comfort, and postoperative complications. Results: all patients operated by all in one procedure were discharged within 24 h from surgery. Slight pain was reported by the majority of patients and (07.69%) of them required pain medication at home. After the 1st postoperative week (95.36%) reported no pain and (04.62%) show bruising genitaliao, (01.54%) had seroma and no wound infection recorded. No relevant limitation of normal activities was reported. There have been no postoperative neuralgias. Conclusion: This new hernioplastyo technique respects the anatomy of the inguinal canal, uses a smaller mesh, and seems to avoid neuralgias with maximum comfort for the patients. We recommended to all in one technique o because gives better results and fewer complications. Keywords: Hernia ;Open mesh inguinal hernia; patients
