RESUMO
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.
RESUMO
INTRODUCTION: The enhanced-view totally extraperitoneal (eTEP) technique, an endoscopically performed Rives-Stoppa method, has been used extensively for ventral hernia repairs. However, in this technique, the necessity of posterior rectus sheath re-approximation and mesh fixation remains unclear. There are a few reports of post-eTEP interparietal hernias (IHs) occurring because of dehiscence of the re-approximated posterior rectus sheath; however, IH secondary to mesh migration is rare. Herein, we report a rare case of IH due to mesh migration after eTEP repair for an incisional hernia. PRESENTATION OF CASE: A 70-year-old man underwent eTEP repair for an incisional hernia using a self-gripping mesh without mesh fixation and posterior rectus sheath re-approximation one year previously, developed an IH. An elective laparoscopic surgery revealed an orifice to the retrorectus space as though the IH sac between the retrorectus muscle and the posterior layer including the bilateral posterior rectus sheaths, peritoneum, and mesh. We placed eight transmural sutures with 0 nylon thread and closed the orifice. The patient was then discharged on postoperative day two and was asymptomatic at 24 months without evidence of ventral hernia recurrence. DISCUSSION: We consider that strenuous activity and deep bending may cause mesh migration or dislocation. If that occurs in the early post-eTEP period without posterior rectus sheaths closure, the vulnerable peritoneal area will be exposed, which consider to be an IH orifice. CONCLUSIONS: Even after using the self-gripping mesh in eTEP repair, mesh fixation remains the best option to prevent postoperative complications, including IH.
