This study attempts to determine if enough pathological abnormalities in gastric remnants from sleeve gastrectomy exist to warrant full pathologic evaluation in all remnants.

Data was collected on patients undergoing sleeve gastrectomy between 08/01/2011 and 06/30/2014. Significant abnormalities were classified as any pathology that might require follow-up or treatment beyond standard follow-up. Age, comorbidities, gender, and Helicobacter pylori titers were analyzed and compared with pathology specimens using 95% confidence intervals and Phi contingency coefficients.

Full pathologic evaluation was available for 351/387 patients (91.2%). No examples of malignancy or dysplasia were identified. Gastritis was the most common abnormality. There was a statistically significant association between preoperative H. pylori and significantly abnormal pathology (p = 0.003). Other comorbidities had no association.

These results suggest that full pathologic evaluation of the gastric remnant following sleeve gastrectomy is unnecessary, particularly when gross pathology is not noted at initial operation.
