Case 2 was a 60-year-old man who presented with repeated attacks of incomplete intestinal obstruction for 2 years' duration and was diagnosed with adult megacolon by double-contrast barium enema (Figure 1a), colonoscopy, and biopsy. TEM resectoscope shaft (Figure 2), and the proximal colonic resection (Figure 1b) was performed extracorporeally at the marked location by first creating a purse-string suture and then inserting a circular stapling anvil into the proximal end of the bowel.
The specimen was exteriorized through the TEM resectoscope shaft through the anus.
