Abbreviation: GERD, gastroesophageal reflux disease.
a
One patient converted from sleeve to bypass for GERD at 6 years and later at 10 years experienced dumping as a complication from bypass.
b
Conversion from sleeve to bypass for fistula and abscess, and later fistulectomia.
c
P values calculated with χ2 test.
d
One patient underwent laparotomy 1 year after gastric bypass and later at 9 years incisional hernia, calculated only once in total count of major complications.
