Total extra peritoneal inguinal hernia repair: a single-surgeon preliminary findings report.

Introduction: Inguinal hernia repair is one of the most frequent operations in general surgery. Various techniques have been used to repair inguinal hernias since the first reconstructive technique described by Bassini in 1887. In 1989 Lichtenstein reported a new technique: tension free inguinal hernia repair. Laparoscopic inguinal hernia repair was introduced in the early 1990s, and soon also became popular. Literature has shown the benefits of laparoscopy (in comparison with open repair) to be mostly related to the more minimally invasive nature of the surgery, having lower wound infection rates, faster recovery, and less postoperative pain.

Aim: To evaluate our totally extraperitoneal (TEP) inguinal hernia repair initial results and compare them to literature data.

Materials And Methods: In a prospective review and analysis, we examined 61 cases of hernia repair via laparoscopy (specifically TEP), performed by a single surgeon, between April 2019 and December 2019 at the Kaspela University Hospital in Plovdiv. The centre's Institutional Review Board approved the study with no specific consents required due to the retrospective, minimal risk nature of the study. The routine informed consent required by the National Insurance Fund has been considered sufficient for the study objectives.The surgical outcome measures included operating time (hours/minutes), conversion, peritoneal injury, surgical emphysema; and the clinical outcome measures included postoperative seroma, post-operative infection, and post-operative chronic groin pain.

Results: Inguinal pain on discharge was characterized as mild by 56 (96.55%) patients and moderate by 2 (3.44%), there were no patients describing the pain as severe. The most frequently reported postoperative complications were annoyance and discomfort (10.34%), swelling (6.9%), seroma (3.44), hematoma (1.72%), paresthesia 1.72% (1); however, only those with seromas required special treatment.

Conclusions: Limitations of the present study include the relatively small number of patients, all cases were operated on by a single surgeon and short postoperative follow-up period, but we are sharing our initial six months results. These results demonstrate that laparoscopic TEP inguinal hernia repair without mesh fixation is a reliable technique, which can reduce postoperative morbidity when applied by experienced surgeons.
