Laparoscopic Fundoplication

6. Should the esophagus be extensively mobilized in laparoscopic fundoplication?

Current Thoughts

1. Less mobilization of esophagus

2. Keep peritoneal barrier b/w esophagus & crura

Current Thoughts

3. Secure esophagus to crura at 8, 11, 1 and 4 o’clock

Laparoscopic Nissen FundoplicationSummary

• The use of stab incisions for instrument access results in significant financial savings to the patient and institution.

• The incidence of transmigration of the fundoplication wrap has been markedly reduced with the use of esophageal-crural sutures and minimal esophageal mobilization.

• The long-term functional results should be equivalent to the open operation. The major advantages lie in reduced discomfort and hospitalization, faster return to routine activities and cosmesis.
