Resection of polyps involving the appendiceal orifice by combined endo-laparoscopic surgery: Two case reports

Figure 1 Endoscopic findings of the laterally spreading tumor encircling the appendiceal orifice and procedure of combined endo-laparoscopic surgery to remove the lesion encircling the appendiceal orifice of the first patient. A: Distant view of the polyp at the appendiceal orifice; B: Close-up view of the polyp at the appendiceal orifice; C: Exploration and localization of the lesion; D: A near-full-thickness incision was made around the lesion; E: Incisions were made through the layers of the cecal wall under laparoscopy; F: The gross specimen revealed markers around the outer edge of the lesion.
