The unknown man explained to the doctor he’d been sat on the toilet using his phone for half an hour while he was trying to poop. The examining doctor found a massive lump – measuring 16 centimetres (16.3 inches) long – sticking out of his anus, which had to be removed through surgery.

The patient said he was spending over half an hour on his phone in the toilet at home, according to Kan Kan News. The incident is said to have happened in Zhongshan, Guangdong Province on February 4. Dr Su Dan, of the Sixth Affiliated Hospital of Sun Yat-sen University said the man was diagnosed with a rectal prolapse, in which the end of the inestines loses its attachment within the body and falls out.

The doctor also said the patient’s situation was particularly severe, saying:

The patient had rectal prolapse since he was four years old, the bulge was able to retract, but he did not treat the condition and the situation got worse.

Medical scans show a ‘ball-shaped’ bulge emerging from the anus, as well as bruises and blood spots along the patient’s intestinal wall. Surgeons were able to remove the lump and the man is now recovering. Rectal prolapse is more common among children or elderly patients, but this condition was worsened by the delay in the descent of the prolapse. Dr Su thought the cause of the descent of the prolapse this time was the long duration spent in the toilet trying to poo as it weakens the muscles in the pelvis. So no matter how appealing it is to sit on the toilet for ages, it’s really not worth it.
