A 67-year-old woman was admitted to our hospital with constipation. Colonoscopy revealed a rectal tumor measuring 10 mm in diameter. Endoscopic mucosal resection of the lesion was performed. Histological examination revealed the diagnosis of rectal cancer invading the submucosa. Therefore, laparoscopic low anterior resection was performed. After the anastomosis, intraoperative endoscopy revealed leaking air bubbles from the site of the anastomosis, and we therefore clipped the anastomotic site with a metallic clip. After the surgery, the patient was discharged without any complications.
