Abstract
Background
One-anastomosis gastric bypass (OAGB) is an accepted bariatric and metabolic surgery
with certain important complications, such as postoperative gastroesophageal reflux
disease (GERD) and bile reflux (BR), which are not well addressed in literature.
Objectives
The present study was conducted to determine the true incidence of postoperative de
novo GERD and BR and their associations with a hiatal hernia (HH).
Setting
The present research setting comprised the Center of Excellence of the European Branch
of the International Federation for the Surgery of Obesity and Metabolic Disorders,
Hazrat-e-Rasoul Hospital, Tehran, Iran.
Methods
The present cohort study recruited 200 patients with morbid obesity undergoing OAGB/minigastric
bypass from December 2016 to February 2018 without any preoperative GERD symptoms.
These patients were followed up for 1 year after the surgery. The incidence of post-OAGB
GERD and BR was determined in all the patients using the GERD symptom questionnaire,
GerdQ.
Results
The mean age of the patients was 41.0 ± 11.6 years. A hernia was observed in 56 (29.2%)
cases and GERD in 37 (19.3%). Hernia was small in 44 (22.9%) cases, medium in 11 (5.7%),
and large in 1 (.5%). HH was found to be significantly correlated with GERD (P = .012).
Conclusion
The important post-OAGB complications, such as GERD and BR, have not been adequately
addressed in literature. The present study found moderate and large HHs to be important
factors for de novo GERD and repairing a HH during OAGB may be essential for preventing
GERD-like symptoms.
