Background
In spite of appropriate preparation, food residue that interferes with endoscopic examination is occasionally observed in an operated stomach. The present study aimed to elucidate the incidence of such food residue and determine its risk factors in gastric pull-up after esophagectomy.
Methods
A total of 116 esophagectomized patients underwent the first postoperative endoscopy to survey their gastric pull-up with a median interval of 14 months (range 6–24) after the surgery. Fasting time was 13–16 h before the examination. The amount of food residue was retrospectively classified from Grade 0 (no food residue) to Grade 4 (a large amount of food residue) by two expert endoscopists.
Results
Among the 116 patients, 73 patients were classified as Grade 0, 23 patients as Grade 1, 10 patients as Grade 2, 9 patients as Grade 3, and 1 patient as Grade 4. Food residue (≥Grade 2) that interfered with the examination was observed in 20 patients (17.2 %). There was no significant association between the food residue and patient baseline characteristics.
Conclusion
The food residue interfering with postoperative endoscopic examination was observed in 17.2 % of all surveyed gastric pull-ups.
