So there's a 55-year-old Chinese farmer who was born with a congenital condition that left him without an anal opening. Without getting too graphic, prior to 2011, he had a surgical hole that he could use to shit, but he also had to extrude it manually. According to an article in Pediatric Clinical Advisor, there's some degree of imperforate anus in approximately 1 in 5,000 live births. But you can imagine this is usually not too big of a deal for people with better health coverage. They can take care of it pretty immediately upon birth. But it can be horrible for someone like a farmer living in China.
