Background:
Obesity is closely related to upper gastrointestinal diseases. China has a high incidence of gastropathy. Postoperative examination of the distal stomach becomes extremely difficult after laparoscopic Roux-en-Y gastric bypass surgery (LRYGB). Whether preoperative routine gastroscopy should be performed at all remains controversial. The objective of this study was to explore the value of routine gastroscopy before performing LRYGB in Chinese patients.
Methods:
The preoperative gastroscopy reports of 180 patients who had undergone LRYGB for morbid obesity and/or metabolic syndrome in the Department of Gastrointestinal Surgery of our hospital from January 2009 to August 2013 were retrospectively analyzed.
Results:
Gastroscopy showed chronic superficial gastritis (n = 159, 88.3%), reflux esophagitis (n = 19, 10.6%), erosion (n = 69, 38.3%), hiatal hernia (n = 5, 2.8%), gastric ulcer (n = 3, 1.7%), duodenal ulcer (n = 32, 17.8%), and gastric polyps (n = 10, 5.6%).
Conclusion:
It is useful to perform gastroscopy before LRYGB. The findings of this investigation can help physicians to develop tailored therapies and procedures and thus improve the prognosis considerably. Gastroscopy should be routinely performed in Chinese patients who are planning to undergo bariatric surgery.
