ERCP in situs inversus: do we need to turn the other way?

ABSTRACT

Endoscopic procedures are difficult in patients with situs inversus owing to left-right reversal of viscera. Conventionally, reversal of the position of the endoscopist in relation to the patient is advocated to overcome the anatomical difficulty. We describe a patient with chronic calcific pancreatitis and pseudocyst of the pancreas who had situs inversus. ERCP was performed with minor modification of maneuvers with the patient in the usual left lateral decubitus and the endoscopist on the left of the table.
