Recto-intercostal Facial Plane Block in Laparoscopic Hiatus Hernia Repair

Hiatus hernia is a prevalent condition in which the stomach or other abdominal organs protrude through the esophageal hiatus of the diaphragm into the thoracic cavity due to elevated pressure within the abdomen. Laparoscopic hernioplasty of hiatal hernia has been confirmed effective and safe in recent years and performed more due to its mini-invasive nature and intraperitoneal view and operating angle. Although patients having laparoscopic hiatus hernia repair experience less pain than open surgery, postoperative pain can still be significant and lead to associated postoperative issues. These issues can include respiratory and other complications, delay in discharge and adverse effects from increasing requirements of systemic analgesia such as opioid. An important consideration in the potential multitude of problems associated with increased opioid use is respiratory depression, sedation, constipation and the propensity for vomiting. Postoperative vomiting can result in the repaired diaphragm enduring excessive pressure and subsequently early recurrence and failure of the procedure. Recently, a novel block named "recto-intercostal fascial plane block" is performed between the recto abdominal muscle and costal cartilages of ribs 6-7 to block the anterior branches of the T6-T9 thoracic nerves, and laterally to the entire lower thorax. The investigators hypothesize that this block may provide perioperative analgesic benefits in patients undergoing Laparoscopic hiatus hernia repair under general anesthesia.
