Single-incision laparoscopic cecectomy for low-grade appendiceal mucinous neoplasm after laparoscopic rectectomy

Figure 1 Computed tomography. The arrow shows a 55 mm × 25 mm, low-density and no-contrast lesion at the appendix.

Figure 2 Colonoscopy. A: Normal image; B: Indigo carmine-stained image. There was an inflated lesion covered with normal mucosa in the appendix, suggesting a tumor under the cecal mucosa (arrows).

Figure 3 Photograph of the operation. A: A 2.5 cm-diameter incision was in the navel; B: The swollen appendix (arrows) and cecum were mobilized by non-touch technique.

Figure 4 Macroscopic image of the removed specimen. The appendix was about 8 cm long and swollen and exhibited a fibrotic wall (arrow; the mucus in the lumen was removed).
