Introduction: Multiple minimally invasive techniques have been described for ventral hernia repair. The recently described enhanced view totally extraperitoneal (eTEP) ventral hernia repair seems an appealing option since it allows to address midline and lateral hernias, placing the mesh in the retromuscular position without the use of traumatic fixation. Aim: To report on the mid-term result of a series of patients with ventral hernias repaired by the eTEP approach. Methods: A retrospective analysis of our case series between June 2017 and December 2019. Demographic and clinical data were gathered. Hernia characteristics, surgical details, hernia recurrences, and complications are reported. Results: 66 patients were included in the study. Median follow-up was 22 months (interquartile range 12–26). 60% of patients were male. Mean age, BMI, % of Type-2 diabetes and % of smoking were 59 ± 12 years, 30 kg/m2, 24% and 23%, respectively. Mean hernia defect size was 5.5 ± 2.9 cm. Forty-three eTEP Rives-stoppa and 23 eTEP-Transversus abdominis release (14 unilateral, 9 bilateral) were performed. 22 inguinal hernias and 15 lateral defects were simultaneously repaired. We report 1 recurrence (1.5%) and 10 surgical site occurrences (15%; 6 seromas, 2 hematomas and 2 surgical site infections). Four patients required reinterventions (6%). Conclusion: eTEP is a promising approach to treat midline hernias and allows the simultaneous treatment of lateral and inguinal defects, keeping the mesh in the retromuscular position. However, comparative studies must be performed to know its real benefit in laparoscopic ventral hernia repair. [ABSTRACT FROM AUTHOR]

Background: Insufficient coverage of the area of a possible groin hernia is an important risk factor in hernia recurrence. To prevent recurrence, it is important to use the appropriate mesh size based on the size of the myopectineal orifice (MPO), which is the weak area of the abdominal wall where inguinal hernias occur. We aimed to estimate the appropriate mesh size for groin hernias by investigating MPO size.Methods: Four hundred and six patients underwent groin hernia repair using a totally extraperitoneal (TEP) approach at the Zeze Hospital between July 2009 and December 2017. We investigated patients' backgrounds, MPO components dimensions, and hernia recurrence, and evaluated the appropriate mesh size.Results: The 359 male and 47 female patients had an average age of 63 ± 15 years. In 171, 147, and 88 cases, hernias were localized to the right, left, and bilaterally, respectively. The number of lateral, medial, femoral, and combined hernias was 317, 124, 11, and 42, respectively. The 95th percentile for the horizontal and vertical lengths in cases of hernia orifice ≥ 3 cm were 9.6 cm and 7.0 cm, respectively, while it was 9.2 cm and 6.4 cm in cases of hernia orifice < 3 cm. We added 2 cm and 3 cm to the 95th percentile for the length and width of the MPO, resulting in 13.2 × 10.4 cm and 15.6 × 13.0 cm in cases with hernia orifice < 3 cm and ≥ 3 cm, respectively. Relapse after TEP occurred in 1 patient (0.2%).Conclusion: The appropriate mesh size for TEP repair, derived from intraoperative MPO measurements, was estimated as 13.2 × 10.4 cm and 15.6 × 13.0 cm when the hernia orifice was < 3 cm and ≥ 3 cm, respectively. Using appropriate mesh sizes based on MPO measurement may reduce groin hernia recurrence after TEP. [ABSTRACT FROM AUTHOR]

Background: Up to now the totally extraperitoneal (TEP) technique is limited to the treatment of inguinal hernias. Applying this anatomical repair concept to the treatment of other abdominal wall hernias, we developed an endoscopic totally extraperitoneal approach (TEA) to treat primary midline ventral hernias, including umbilical and epigastric hernias, in which for mesh placement, an anatomical space is developed between the peritoneum and the posterior rectus sheath in the ventral part of the abdominal wall (preperitoneal space). Methods: Between September 2017 and December 2019 according to the selection criterions, 28 consecutive primary midline ventral hernias were repaired using TEA. After extensive endoscopic development of the midline extraperitoneal plane, which was started in the suprasymphysic area, and reduction of the hernia sac, the hernia defect was closed and a large mesh was placed in the preperitoneal position to enforce the anterior abdominal wall. Results: All operations were successfully performed without conversion to open surgery. The mean operation time was 103.3 min (range 85–145 min). Patient-reported postoperative pain was qualitatively mild with a mean pain visual analogue scale score of 1.9 on postoperative day 1. The average hospital stay was 1.9 days (range 1–3 days). Three patients developed minor complications and were treated with no long-term adverse effects. Readmissions within 30 days or hernia recurrences were not observed with a mean follow-up period of 18 months (range 10–27 months). Conclusion: In selected cases, TEA is a safe and feasible minimally invasive alternative in treating primary ventral hernias. This technique preserves the anatomical and physiological structure of the abdominal wall and may significantly reduce trauma and postoperative complications. Additionally, anti-adhesion-coated meshes and fixation tackers are not required, thus being cost-effective. Further studies are necessary to proof the true clinical efficacy in comparison to well-known alternative techniques. [ABSTRACT FROM AUTHOR]
