A preliminary multicenter evaluation of endoscopic sublay repair for ventral hernia from China

Abstract

Background For ventral hernia, endoscopic sublay repair (ESR) may overcome the disadvantages of open sublay and laparoscopic intraperitoneal onlay mesh repair. This retrospective study presents the preliminary multicenter results of ESR from China. The feasibility, safety, and effectiveness of ESR were evaluated; its surgical points and indications were summarized. Methods The study reviewed 156 ventral hernia patients planned to perform with ESR in ten hospitals between March 2016 and July 2019. Patient demographics, hernia characteristics, operative variables, and surgical results were recorded and analyzed. Results ESR was performed successfully in 153 patients, 135 with totally extraperitoneal sublay (TES) and 18 with transabdominal sublay (TAS). In 19 patients, TES was performed with the total visceral sac separation (TVS) technique, in which the space separation is carried out along the peritoneum, avoiding damage to the aponeurotic structure. Endoscopic transversus abdominis release (eTAR) was required in 17.0% of patients, and only 18.3% of patients required permanent mesh fixation. The median operative time was 135 min. Most patients had mild pain and resume eating soon after operation. No severe intraoperative complications occurred. Bleeding in the extraperitoneal space occurred in two patients and was stopped by nonsurgical treatment. Seroma and chronic pain were observed in 5.23 and 3.07% of patients. One recurrence occurred after TAS repair for an umbilical hernia. Conclusion ESR is feasible, safe, and effective for treating ventral hernias when surgeons get the relevant surgical skills, such as the technique of “partition breaking,” TVS, and eTAR. Small-to-medium ventral hernias are the major indications.

Comparative review of outcomes: single-incision laparoscopic total extra-peritoneal sub-lay (SIL-TES) mesh repair versus laparoscopic intraperitoneal onlay mesh (IPOM) repair for ventral hernia

“…Recently, ESR for VH has been reported by an increasing number of scholars [ 3 – 8 , 11 , 16 – 19 ]. Although this technique is known by several names, including totally endoscopic sub-lay and enhanced-view TEP, at its core, it involves using laparoscopy to mimic open sub-lay repair.…”

“…Unfortunately, it is challenging to separate and close the thin peritoneal flap with these approaches without robotic assistance. We began to realize the clinical value and prospects of this technique in China, and in 2016, we named it endoscopic sub-lay repair (ESR) [ 11 ]. ESR combines the total extra-peritoneal sub-lay (TES) approach and the transabdominal sub-lay (TAS) approach.…”

Preperitoneal space, is it an ideal layer for endoscopic sublay repair of ventral hernia?

“…[1] Recently, some surgeons successfully transferred open sublay repair to endoscopic sublay repair (ESR), which may avoid the wound events after open procedure and potential risks of intra-abdominal injury and mesh complications from Lap-IPOM repair. [1][2][3] Weidong Wu and Huiyong Jiang contributed equally to this article.…”

“…There are two approaches to realize ESR: Totally extraperitoneal sublay (TES) and transabdominal sublay (TAS). [2][3][4] In literature, both retrorectus and preperitoneal space were employed in TAS. However, the preperitoneal space separation was realized mostly by Robotics.…”

Employing a Xiphoid-umbilicus Approach in an Endoscopic Totally Extraperitoneal Procedure for the Preperitoneal Repair of Midline Ventral Hernias

“…M ore articles on endoscopic sublay repair (ESR) of ventral hernias have been published recently because ESR overcomes the disadvantages of open sublay repair, which has more surgical site events and avoids the risk of laparoscopic intraperitoneal onlay mesh placement. [1][2][3][4][5] There are 2 procedures for ESR, that is, totally extraperitoneal sublay (TES) [1][2][3][4] and transabdominal sublay. [5][6][7] In China, TES is implemented more frequently.…”
