Case 1. For want of a Wine cabinet
We kick off this series of cases with a 52 year old man who stumbled into the emergency room with a real pain in the ass. He owned up to the emergency room staff that he had a habit of placing objects in his own rectum for sexual gratification. His latest attempt involved a wine glass. Unfortunately the wind glass got turned around in his rectum, making it impossible for him to remove it. After two days, he finally took himself to hospital. All of the doctor attempts at pulling the glass out failed, and eventually he had to go into surgery.
They opened up his abdomen and squeezed out of the colon via a surgical incision.
Case 2. Ball in the buttocks
Our next victim had managed to insert a ball into their anus. At first, the doctors tried giving him a hefty dose of laxatives. When this didn't work they tried to pull the ball out with an endoscope, but the tiny pincers on it couldn't get any purchase on the ball. In the end, they had to put the patient under general anaesthesia and scoop out the ball with two sets of forceps. This was successful, and the patient could go home the next day.
Case 3. Bottling it
The victim (and I guess perpetrator) in this case had a history of inserting objects up his arse for sexual pleasure. The staff couldn't get any purchase on the object just by going through the anus. They had to perform surgery, which revealed that the offending object was an eight centimetre wide bottle.
Case 4. Design Flaw
One must assume that the people who design vibrators try to ensure that the don't get lost in whatever orifice they are inserted in. That would be a key safety feature, unless they thought that their customers first thought after vaginally or anally engorging the vibrator would be to buy another one. Repeat Sales !
In this final case, we have a gentleman who had suffered from that exact problem during sex with his partner. The vibrator was to slippery to grip with endoscopic forceps, and so the patient had to go into surgery to get it out. If only there were easy holds for endoscopic forceps designed into vibrators, it would save on surgery. Think about it vibrator manufacturers !
