A 47-year-old man was left in extreme pain and needed surgery after he inserted a water-glass into his rectum.

The Nepalese man arrived at the emergency department admitting the object had been inside him for three days.

Initially, the man said it had happened by accident before revealing he had inserted the glass himself for sexual gratification while intoxicated, according to the Journal of Nepal Medical Centre.

The man hadn’t had a bowel movement in two days, but was able to pass wind, and he had no bleeding but was in a lot of pain.

The man said he had tried to remove the glass himself but failed.

After an X-ray was done, doctors tried to remove it but couldn’t get a grasp on the glass as it was inverted.

Medical staff then performed an exploratory laparotomy, which is a surgery to open up the abdomen.

At that point, they attempted to move the glass out by “milking” or squeezing the lower intestine.

“Milking was attempted to deliver the glass through the anus, but this was unsuccessful as the glass was high up, inverted and tightly wedged,” the journal explained.

“Hence sigmoid enterostomy was done and the glass was extracted.”

An enterostomy is the surgical incision into an intestine, allowing doctors direct access to the glass.

The man remained in hospital for seven days recovering from the incident.

And two months later, at a follow-up appointment, doctors said he was well and had fully recovered.

The most common reasons for an object inserted into the anus is sexual gratification.

Common symptoms are abdominal pain, constipation and rectal bleeding.

Typically, people try to remove the object themselves several times before turning up to the hospital out of embarrassment.
