The enhanced-view totally extraperitoneal (eTEP) technique has been previously described for Laparoscopic Inguinal Hernia Repair. We present a novel application of the eTEP access technique for the repair of ventral and incisional hernias.Retrospective review of consecutive laparoscopic retromuscular hernia repair cases utilizing the eTEP access approach from five hernia centers between August 2015 and October 2016 was conducted. Patient demographics, hernia characteristics, operative details, perioperative complications, and quality of life outcomes utilizing the Carolina's Comfort Scale (CCS) were included in our data analysis.Seventy-nine patients with mean age of 54.9 years, mean BMI of 31.1 kg/m, and median ASA of 2.0 were included in this analysis. Thirty-four percent of patients had a prior ventral or incisional hernia repair. Average mesh area of 634.4 cm was used for an average defect area of 132.1 cm. Mean operative time, blood loss, and length of hospital stay were 218.9 min, 52.6 mL, and 1.8 days, respectively. There was one conversion to intraperitoneal mesh placement and one conversion to open retromuscular mesh placement. Postoperative complications consisted of seroma (n = 2) and trocar site dehiscence (n = 1). Comparison of mean pre- and postoperative CCS scores found significant improvements in pain (68%, p < 0.007) and movement limitations (87%, p < 0.004) at 6-month follow-up. There were no readmissions within 30 days and one hernia recurrence at mean follow-up of 332 ± 122 days.Our initial multicenter evaluation of the eTEP access technique for ventral and incisional hernias has found the approach feasible and effective. This novel approach offers flexible port set-up optimal for laparoscopic closure of defects, along with wide mesh coverage in the retromuscular space with minimal transfascial fixation.

The Rives-Stoppa procedure is used for ventral hernia repair but requires a large midline incision. This report describes a new, totally endoscopic approach to the retromuscular plane, corresponding to a reversed totally extraperitoneal procedure, to perform sublay repair of primary and secondary ventral hernias. This totally endoscopic sublay (TES) repair is described in detail, and its safety and efficacy were evaluated.In this prospective study, we assessed 26 consecutive primary and secondary epigastric midline ventral hernias that were repaired between July 2017 and July 2018 using the TES procedure. A large mesh was placed in the retrorectus position using this minimally invasive approach. Indications for this procedure include umbilical, epigastric, incisional hernias, and rectus diastasis.All TES procedures were successfully performed without conversion to an open operation. The mean operative time was 106.6 ± 29.1 min (range 75-205), with average mesh area of 318.8 cm for an average defect area of 26.5 cm. Postoperative pain was mild, and the mean visual analog scale (VAS) under physical stress (e.g., climbing stairs) was 2.4 at the third postoperative day. The average postoperative hospital stay was 2.8 ± 0.8 days (range 2-5). Two patients developed postoperative seroma, with no final adverse effect. No recurrence nor readmissions within 30 days was observed during a mean follow-up of 9.2 ± 4.4 months.Initial experiences with this technique show that the TES procedure is safe and reliable, requires no specific instruments, and is highly reproducible. There is no need for an expensive anti-adhesion mesh or fixation device, making it cost-effective.

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.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.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.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.

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.

Purpose: Many patients develop a parastomal hernia within the first 2 years of stoma formation, and even surgical repair is associated with high recurrence rates. An intraperitoneal approach is typically used for the laparoscopic repair of parastomal hernia; it is unknown whether a totally extraperitoneal technique (TEP) is feasible. Here we describe a laparoscopic TEP approach using a modified Sugarbaker method for the repair of parastomal hernia.

International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project.The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched. Quality assessment was performed using Scottish Intercollegiate Guidelines Network checklists. The guidelines were presented at the 38th European Hernia Society Congress and each key question was evaluated in a consensus voting of congress participants.End colostomy is associated with a higher incidence of parastomal hernia, compared to other types of stomas. Clinical examination is necessary for the diagnosis of parastomal hernia, whereas computed tomography scan or ultrasonography may be performed in cases of diagnostic uncertainty. Currently available classifications are not validated; however, we suggest the use of the European Hernia Society classification for uniform research reporting. There is insufficient evidence on the policy of watchful waiting, the route and location of stoma construction, and the size of the aperture. The use of a prophylactic synthetic non-absorbable mesh upon construction of an end colostomy is strongly recommended. No such recommendation can be made for other types of stomas at present. It is strongly recommended to avoid performing a suture repair for elective parastomal hernia. So far, there is no sufficient comparative evidence on specific techniques, open or laparoscopic surgery and specific mesh types. However, a mesh without a hole is suggested in preference to a keyhole mesh when laparoscopic repair is performed.An evidence-based approach to the diagnosis and management of parastomal hernias reveals the lack of evidence on several topics, which need to be addressed by multicenter trials. Parastomal hernia prevention using a prophylactic mesh for end colostomies reduces parastomal herniation. Clinical outcomes should be audited and adverse events must be reported.

In 2014, the International Endohernia Society (IEHS) published the first international "Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias." Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature.For the development of the original guidelines, all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based Medicine. For the present update, all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne), the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included.Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques-minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite insufficient evidence with respect to these new techniques, it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields.Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initial guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before.

To evaluate the feasibility, safety, and efficacy of the lateral single-incision laparoscopic totally extraperitoneal (L-SILTEP) approach in patients with inguinal hernia who had contraindications to the midline approach. This study included 58 patients who underwent L-SILTEP. Data on their baseline characteristics and perioperative details were collected. Quality of life and cosmetic satisfaction assessments were performed. Of the evaluated patients, 25.9% had a history of middle and lower abdominal surgery and 10.3% had skin diseases around the umbilicus. The mean surgical duration, blood loss volume, and incision length were 53.5 (± 22.3) min, 7.2 (± 9.7) mL, and 2.0 (± 0.13) cm, respectively. Additionally, 29.3% of patients experienced intraoperative peritoneal rupture, and one patient had epigastric vessel bleeding. The 6-, 24-, and 48-h postoperative pain scores were 3.0 (± 0.6), 1.6 (± 0.6), and 1.1 (± 0.4), respectively. Postoperative complications included seroma (n = 3), hematoma (n = 1), and scrotal edema (n = 1). The surgical incision in the L-SILTEP approach was more aesthetically pleasing than that in previous surgeries. Approximately 17.2%, 8.6%, and 10.3% of patients reported pain, mesh sensation, and movement limitation, respectively. Severe or disabling symptoms were not reported, and there were no cases of 30-day readmissions. Hernia recurrence or incisional hernia was not observed over a mean follow-up duration of 14.6 (± 6.1) months. L-SILTEP can be used for patients with contraindications to the midline approach. Furthermore, it is a safe and effective procedure.© 2024. The Author(s).

To compare outcomes between single-incision laparoscopic totally extra-peritoneal sub-lay (SIL-TES) mesh repair and laparoscopic intraperitoneal onlay mesh (IPOM) repair of ventral hernia (VH). A retrospective selection of 104 patients who underwent VH repair (50 and 54 in the SIL-TES and IPOM groups, respectively) was made. Patient data were collected, and quality of life was evaluated using Carolinas Comfort Scale (CCS) 1 month and 3 months after surgery. There were no significant differences in sex, American Society of Anesthesiologists class, defect size, mesh area, estimated blood loss, and complication rate between the groups. Age was lower, body mass index was higher, prevalence of primary VH was significantly higher (p < 0.0001), and pain was less at 24 and 48 h post procedure (p < 0.0001) in the SIL-TES group. Drainage placement was more (p < 0.0001), operation time was shorter (p = 0.012), and hospitalization duration and total hospitalization cost were greater in the IPOM group than that in SIL-TES group (8.3 ± 0.3 vs 4.3 ± 0.4 days, p < 0.0001; $7126.9 ± 141.4 vs $2937.3 ± 58.3, p < 0.0001, respectively). Pain and movement limitation scores evaluated by CCS were significantly worse at 1 month (4.93 ± 0.28 vs 1.75 ± 0.28: p < 0.0001; 2.52 ± 0.24 vs 1.15 ± 0.18: p < 0.0001, respectively) and 3 months (4.32 ± 0.37 vs 0.9 ± 0.29: p < 0.0001; 2.06 ± 0.25 vs 0.69 ± 0.11: p < 0.0001, respectively) in IPOM group, compared with the according scores in SIL-TES group. There was no readmission within 30 days and no hernia recurrence at mean follow-up of 12 months. SIL-TES mesh repair is safe and effective and is superior to IPOM repair.© 2022. The Author(s).

Lumbar hernia is a rare disease with low incidence, and no golden standard surgical procedure has been established for lumbar hernias. The single-incision laparoscopic totally extraperitoneal sublay (SIL-TES) technique became a novel surgical technique for lumbar hernias. This retrospective study included 20 patients who underwent SIL-TES repair for lumbar hernia between April 2020 and March 2024. The baseline patient characteristics, intraoperative data, postoperative data, satisfaction score, and Carolina Comfort Scale scores were collected. The results revealed that the SIL-TES technique for lumbar hernia repair is associated with a low complication rate, nonrecurrence, high satisfaction score, and high quality of life after surgery. The SIL-TES technique could be a feasible and effective surgical technique for lumbar hernias. A controlled study is needed for further confirmation.

Parastomal hernia is the most common complication after stoma formation with an incidence that approaches 50% at 2 years postoperatively. In the last decade, different approaches of minimally invasive procedures have been proposed for the treatment of parastomal hernia. Nevertheless, the superiority of one technique over the others remains still unclear. Our objective was to update and systematically analyze current state of research concerning the postoperative outcomes of the four most prevalent minimally invasive techniques.

Open retromuscular mesh repair has become a standard procedure in incisional hernia repair. This technique led to a significant decrease of recurrences. Recurrences after this technique typically occur at the upper mesh border and are a result of the technical complexity of reaching the postulated underlay of 5 cm in the region of the linea alba. We performed an anatomical study in human corpses to investigate the abdominal wall with its different structures, with emphasis on the overlap of the mesh under the linea alba. The overlap can be achieved by incision of the posterior lamina of the rectus sheath, on both sides close to the linea alba. The incision opens the preperitoneal space and appears in the shape of a "fatty triangle". The anterior lamina of the rectus sheath above the hernia defect remains intact and facilitates a sufficient thrust bearing for a retromuscular mesh implantation. Knowledge of the anatomy and preparation of the "fatty triangle" enables a mesh positioning according to the principles of retromuscular mesh repair.
