P052 EARLY OPERATIVE OUTCOMES OF ENHANCED-VIEW TOTALLY EXTRA PERITONEAL REPAIR(ETEP) FOR VENTRAL HERNIAS

Aim Early operative outcomes of enhanced-view totally extraperitoneal repair (eTEP) for ventral hernias Material and Methods We have retrospectively analysed the date of 41 patients who underwent an eTEP procedure on between November 2018 and April 2021 by a single surgeon and monitored until May 2021. Results During the study period, 29 endoscopic transversus abdominis muscle release and 12 endoscopic Rives-Stoppa techniques were performed to repair incisional (30), umbilical (6), epigastric (3), and spigelian, and parastomal hernias occurred in 1 patient each. The mean age was 68.0 years, mean BMI was 26.4 kg/m2. The hernial orifice centers were as follows: M2 in 7, M3 in 23, M4 in 5, L2 in 4, L4 in 1, and M2 and L2 (2 orifices) in 1 patient. Nine cases of large incisional hernia (width ≥10cm) were included. An average mesh area of 624cm2 was used for an average defect area of 57cm2. Mean operative time, blood loss, and length of hospital stay were 278 min, 5 ml, 6 days, respectively. Only one case was converted to an open operation due to presence of severe adhesions. Postoperative complication consisted of hematoma (n = 1) and a small bowel obstruction due to a tear of the posterior sheath (n = 1). There was no hernia recurrence at mean follow-up of 448 days. No patient reported significant pain at the surgical site at the first postoperative follow up. Conclusions Judging from our short-term results, eTEP approach for ventral hernias can be an attractive option for selected cases.

P053 COMPARISON OF CLINICAL OUTCOMES BETWEEN INTRAPERITONEAL ONLAY MESH REPAIR (IPOM PLUS) AND ENHANCED-VIEW TOTALLY EXTRAPERITONEAL REPAIR (ETEP) FOR VENTRAL HERNIAS

Aim We have been performing intraperitoneal on lay mesh repair (IPOM plus) as the standard laparoscopic procedure for ventral hernia in our department. We introduced enhanced-view totally extraperitoneal repair (eTEP) for ventral hernia repair in 2018, and have performed 31 cases so far. We compared the outcomes of IPOM Plus and eTEP at our institution. Material and Methods Ventral hernia cases who underwent surgery at our department between 2018 and 2020 were included in the study. The postoperative outcomes and complications of the IPOM Plus and eTEP groups were evaluated retrospectively. Results There were 12 cases of IPOM plus, and all were incisional hernias. There were 31 cases of eTEP, including 7 cases of primary hernias and 24 cases of incisional hernias. Transversus abdominis muscle release (TAR) was added in 24 cases. The mean hernia size was 6.6 x 7.9 cm with IPOM Plus and 8.0 x 10.1 cm with eTEP, and the average meshes size was 15.5 x 22.0 cm and 20.3 x 23.6 cm, respectively. The mean postoperative hospital stay was 7.8 days and 5 days. Postoperative complications included 1 case of mesh bulging and 1 case of recurrence in the IPOM Plus group, 1 case of seroma and 1 case of intestinal obstruction in the eTEP. Conclusions The surgical outcomes for ventral hernias up to 8 cm wide were similar for IPOM Plus and eTEP. The eTEP can insert a larger mesh and may be useful for wider hernias (>8cm).

P062 IMPLEMENTATION OF ETEP (EXTENDED TOTALLY EXTRAPERITONEAL REPAIR) AS A NEW METHOD OF INCISIONAL HERNIA REPAIR

Aim To assess the outcomes of implementation of extended Totally Extraperitoneal Repair (eTEP) for incisional hernia in our clinic. Material and Methods In our clinic abdominal wall hernias are predominantly repaired in eMILOS (endoscopic Mini or Less Open Sublay)-technique. However, we hoped for advantages in repairing incisional hernias in eTEP-technique. From 19.09.2019 till 28.04.2021 there were 13 patients with incisional hernias included to be operated in eTEP-technique. Results Among 13 patients, mean age was 64,6 years (range 47 – 78 years), 7 females (54%) and 6 males (46%). Average diameter of the hernia was 6,46 cm (range 2 – 14 cm). The mean Body Mass Index of the patients was 29,41 kg/m² (range 18,4 – 48,76 kg/m²). The mean duration of the operation was 162,38 minutes (range 106 – 237 minutes). The mean surface of the mesh was 612 cm² (range 225 – 1200 cm²). Hospital stay lasted mean of 5,8 days (range 2 – 28 days). We observed one postoperative complication as a lung artery embolism occurred in one patient with preperitoneal heamatoma due to needed anticoagulation. Till today we have not observed any recurrence. Conclusions Our study shows that a new method of incisional hernia repair with mesh placement can be a safely implemented and may have advantages compering with other laparoscopic methods. It has low complication rate, shows good cosmetic results and is cost effective.

Endoscopic Totally Extraperitoneal Repair of Parastomal Hernia: A Case Report

A parastomal hernia is a type of incisional hernia that occurs in abdominal integuments in the proximity of a stoma. It is a frequent late complication following colostomy. Surgical repair is currently the only treatment option for parastomal hernia. Here we present the case of a 74-year-old patient with parastomal hernia and a history of open surgery treated with a totally extraperitoneal (TEP) endoscopic approach. There was no recurrence of the hernia at the 3-month follow-up. We discuss the feasibility and possible operative approaches for endoscopic repair of parastomal hernia with the TEP technique.

The Comparison of Balloon and Camera Dissection of the Preperitoneal Space in Totally Extraperitoneal Repair Hernia Repair. Our Initial Experience!

Purpose. To perform totally extraperitoneal repair of a hernia, it is essential to create a working space for the placement of instruments. In this study, we aimed to compare balloon dissection (BD) and camera or telescopic dissection (CD) with respect to the surgical outcomes, without considering the cost-effectiveness. Methods. Forty consecutive, healthy, unilateral inguinal hernia patients who underwent Totally Extraperitoneal Repair hernia repair were randomized into 2 groups according to whether they received BD or CD. The perioperative demographic characteristics were recorded. All the operations were video recorded from the beginning to the end of each procedure. The virtually constructed periods of the procedures were evaluated by another surgeon who watched each video. The time spent for each period, the severity score assigned by the surgeon, the total operation time, the peritoneal laceration rate, the presence of early and late postoperative pain, the number of postoperative visits, the total analgesic requirements, and the complications were recorded. Results. The demographic properties of the patients, the perioperative and postoperative complications, and the severity scores in the BD and CD groups were statistically similar. The total operating time and the time from the dissection of the peritoneum to the reduction of the hernia sac were significantly longer in the CD group. Post-discharge analgesic consumption, Visual Analog Scale scores, and the number of visits were similar between the groups. Conclusions. The dissection of the working space in the preperitoneal area can be achieved using camera dissection without the risk of common complications associated with balloon dissection, particularly balloon rupture.
