Endoscopic papillectomy: Data of a prospective observational study

Figure 1 Steps of endoscopic papillectomy. A: Endoscopic view onto the local tumor site (adenomatous papilla of Vater); B: Insertion of a tube through the papilla of Vater for cholangiography; C: Postinterventional endoscopic view onto the papillary region after endoscopic papillectomy; D: Tumor specimen ex situ.

Figure 2 Diagnostic workup of a representative case (tubulovillous adenoma of the papilla). A: Initial endoscopic view onto the tumor-like lesion of papillary region; B: Endoscopic ultrasonography-based imaging indicating echo-poor tumor lesion but no infiltrating tumor growth; C: Histopathological picture (HE staining; magnification, × 40).

Figure 3 Suggested institutional algorithm on the diagnostic and therapeutic endoscopic approach in suspicious tumor-like lesions of the papilla of Vater. ERCP: Endoscopic retrograde cholangiopancreatography. EUS: Endoscopic ultrasonography.
