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.

Carbon dioxide embolism during transoral endoscopic thyroidectomy: A case report and literature review.

The creation of the surgical space in transoral endoscopic thyroid surgery may put the anterior jugular vein at risk for injury and possibly lead to carbon dioxide (CO2 ) embolism. Although rare, CO2 embolism is potentially fatal. We report a case of a 67-year-old female who underwent transoral endoscopic thyroidectomy vestibular approach (TOETVA) for a benign thyroid disease. Intraoperatively, the anterior jugular vein was inadvertently lacerated. The end-tidal (Et)CO2 , O2 saturation, heart rate, and blood pressure suddenly decreased. The patient eventually became asystole. Cardiopulmonary resuscitation was performed with a return of spontaneous circulation (ROSC). We successfully ligated the injured vessel and terminated the procedure. A literature review of CO2 embolism during transoral thyroid surgery is presented, focusing on presentation, management, and prevention. Since TOETVA is still in preliminary clinical application, especially in developing countries, CO2 embolism may not be uncommon during the initial phase of the learning curve. Surgeons and anesthesiologist should be aware of this possibility.

Laparoendoscopic single-site surgery in inguinal hernia repair.

Laparoendoscopic single-site surgery (LESS) for laparoscopic inguinal hernia repair (IHR) offers the potential for excellent cosmetic outcomes and maximization of the inherent advantages of minimally invasive surgery. LESS IHR is associated with a steep learning curve, which is attributable to both the IHR technique itself and the single-site technique. The technical obstacles in the single-site technique may be mitigated by employing certain maneuvers and strategies that minimize clashing between instruments and improve freedom of movement. The current literature consistently points out the inherent challenges in LESS IHR, with its longer operative time compared to that of conventional laparoscopic IHR. LESS IHR performed by capable operators has comparable complication rates, duration of hospital stay, and incidence of recurrence as conventional laparoscopic IHR. LESS IHR is both feasible and safe. Given its excellent cosmetic outcome, it is likely to be sought by younger patients who are concerned with scar formation. The use of robotics may bypass the technical challenges in LESS, but cost considerations in their usage will likely persist.
