GORD is a progressive, deterioration of the OG junction
Hill Grade IV requires very invasive surgery that may involve a thoracotomy

Surgery– antireflux operations
• Belsey Mark IV operation - 270 degree wrap, left thoracotomy, transthoracic fundoplication
• Nissen (transabdominal) fundoplication - 360 degree wrap via abdomen, also done via laparoscopic or thoracic approach
• Hill (transabdominal) repair (posterior gastropexy) - uses arcuate ligament to re-establish intra-abdominal position of distal esophagus, 270 degree wrap
• Toupet (laparoscopic) fundoplication - 270 degree posterior wrap
Repairs the underlying anatomic pathology of the disease by:
1. Wrapping of the fundus and cardia around the lower esophagus
2. Full thickness plication with permanent suturing of esophagus and stomach
3. Restoring or lengthening the intra-abdominal esophageal length
4. Recreating the angle of His5. Augmenting high pressure zone of esophagus6. Closing the crural defect in the presence of a hiatal hernia.

Toupet repair & Nissen fundoplicationToupet repair & Nissen fundoplication
In the Toupet repair, the fundus is wrapped 270 degrees around the distal esophagus. Securing the fundoplication entails
suturing the fundus on either side of the esophagus. Identification of the anterior vagal branch helps prevent
incorporation into a suture. Suturing the lateral aspects of the wrap to the crural edges stabilizes the repair. (Source: Peters,

o TIF Leverages the experience and success of Endoscopy with the gold standard treatment for GERD.
o TIF is a full thickness, Esophagogastric fundoplication utilizing poly-propylene suture material.
o TIF is the next logical step in the progression for a fundoplication from a thoracic, to abdominal, to laparoscopic and now endoscopic.

New SAGES Position StatementNew SAGES Position Statement
Endolumenal Therapy (ELT)– Transoral incisionless
approach for reconstructive surgical procedures
SAGES position statement on ELT 1. Positions ELT as the Future of
Surgery2. Endorses ELT approach as a
benefit in safety and recovery time of patients and their employers
3. Represents ELT as the up-in-coming procedure of choice for GORD patients
4. Aggressively supports the reimbursement of these procedures

Surgery– antireflux operations
• in general - increases lower esophageal sphincter (LES) tone, involves vagotomy, fundoplication = create ring around LES (wrap with gastric fundus)
• Belsey Mark IV operation - 270 degree wrap, left thoracotomy, transthoracic fundoplication
• Nissen (transabdominal) fundoplication - 360 degree wrap via abdomen, also done via laparoscopic or thoracic approach
• Hill (transabdominal) repair (posterior gastropexy) - uses arcuate ligament to re-establish intra-abdominal position of distal esophagus, 270 degree wrap
• Toupet (laparoscopic) fundoplication - 270 degree posterior wrap
• Transoral Incisionless Fundoplication – 270-310 degree wrap, Transoral Fundoplication for patients with hiatal defect of less than 2cm.
