Enhanced-view totally extraperitoneal repair in a morbidly obese patient with epigastric and umbilical hernias in combination with rectus diastasis: A case report

INTRODUCTION

The use of enhanced-view totally extraperitoneal (eTEP) repair for patients with ventral hernias has become more widespread due to its ability to prevent mesh-and-tacker-related complications by placing the mesh in the retrorectus space. However, the efficacy of eTEP repair in obese patients remains unknown. Herein, we report a case of a morbidly obese patient with epigastric and umbilical hernias in combination with a rectus diastasis repaired using the eTEP technique.

PRESENTATION OF CASE

A 42-year-old man with a history of spontaneously reduced incarcerated epigastric hernia two weeks previously was referred to our hospital. His body mass index (BMI) was 42.9 kg/m2. Abdominal computed tomography revealed a small epigastric hernia, an umbilical hernia, and a rectus diastasis. We performed eTEP repair. The postoperative course was uneventful, and the patient was discharged on postoperative day 3. There has been no evidence of hernia recurrence after a follow-up period of 2 years.

DISCUSSION

We consider that the eTEP technique is rarely affected by intra-abdominal fat because endoscopic manipulation is performed in the bilateral retrorectus and preperitoneal spaces. Moreover, the eTEP allows the epigastric artery perforator to be spared. Therefore, eTEP repair is considered the best surgical option for morbidly obese patients with ventral hernias in combination with rectus diastasis.

CONCLUSIONS

This case provides support for the efficacy of eTEP repair in morbidly obese patients with epigastric and umbilical hernias in combination with a rectus diastasis.

Outcomes after ventral hernia repair using the extended totally extraperitoneal approach: Initial experience from the Philippines

INTRODUCTION

Newer extraperitoneal techniques of laparoscopic ventral/incisional hernia repair (LVIHR) have been continually introduced since the popularity of the laparoscopic intraperitoneal onlay mesh technique began in 1993. One of which is the extended totally extraperitoneal (eTEP) approach allowing wide mesh augmentation, concurrent repair of diastasis recti, and performance of transversus abdominis release (TAR) for large/complex hernias. However, minimally invasive/laparoendoscopic ventral hernia repair is not yet widely adopted in the Philippines. We aim to share our preliminary experience with LVIHR using the eTEP approach.

METHODS

This was a retrospective review of all consecutive eTEP repairs for ventral hernia between January 2019 and September 2023. The clinical profiles of all patients were gathered. Hernia characteristics, operative profile, and postoperative outcomes were reported.

RESULTS

Thirty-five patients were included in the study with a mean age of 54.7; 60% were incisional hernias, and the most common hernia location was the umbilical area. A defect size between 4 and 10 cm was reported in 54.3%. eTEP-TAR was necessary in 12 patients. At a median follow-up of 16 months, two patients developed seroma, one hematoma, and two surgical site infections. All were successfully managed conservatively. Only one patient developed recurrence.

CONCLUSION

eTEP approach is safe and feasible for repairing ventral hernias. Our preliminary experience showed acceptable outcomes similar to the published literature. Surgeons interested in this technique should be familiar with the abdominal wall anatomy, carefully select patients during preoperative planning, and undergo mentorship with hernia surgeons experienced with the technique to shorten the learning curve.

[Incisional hernias: minimally invasive surgical procedures]

BACKGROUND

In recent years many new surgical techniques for minimally invasive treatment of ventral hernias have been developed and introduced. This review article presents these new minimally invasive surgical techniques, such as extended totally extraperitoneal (eTEP) repair, mini or less open sublay (MILOS), endoscopic-assisted linea alba reconstruction (ELAR), the ventral transabdominal preperitoneal patch (TAPP) technique, intraperitoneal onlay mesh (IPOM) plus and laparoscopic intracorporeal rectus aponeuroplasty (LIRA) and discusses recently published results.

RESULTS

Modern minimally invasive techniques for the treatment of ventral hernias have the potential to reduce surgical site infections, lower postoperative pain and lead to a shorter duration of hospital stay compared to the classical open hernia repair; however, especially techniques with a retromuscular mesh position are technically challenging due to the preparation in a limited space and difficult to perform endoscopic sutures and necessitate detailed knowledge of the anatomy of the abdominal wall. The treatment of larger hernias in particular should therefore only be carried out under the prerequisite of extensive experience and case numbers.

CONCLUSION

The new endoscopic and endoscopically assisted techniques for treatment of ventral hernias enable the experienced laparoscopic surgeon to primarily and secondarily treat ventral hernias with minimally invasive techniques.
