Single session panendoscopy. Indications and expectations for yield

To assess the indications and yield of single session panendoscopy (SSPE), patients who underwent colonoscopy and esophagogastroduodenoscopy (EGD) at the same time were retrospectively reviewed. Endoscopy records and patient charts of 101 patients who underwent SSPE during a 45-month period were analyzed for demography, indication, and results. Average age was 72.9 years. Common indications were positive occult blood tests (74%), anemia (28%), altered bowel habits (15%), and iron deficiency (13%). Most frequent findings at colonoscopy included diverticulosis (47%), polyps (37%), hemorrhoids (28%), and arteriovenous (AV) malformations (13%). Nine cases of cancer were found, seven of which were right-sided. Colonoscopy was normal in 12 per cent. EGD findings include esophagitis (55%), hiatal hernia (47%), and gastritis (33%). Eleven per cent were normal. Occult blood loss is not predictive of either a positive or negative study. SSPE is a safe and specific approach; however, based on this study, colonoscopy is recommended as the initial study for occult blood loss with plans to proceed to EGD when the lower endoscopy is normal. Even when the colonoscopy suggests the etiology for occult blood loss, EGD will yield a significant number of treatable and unsuspected lesions.
