Aeon Surgery, Colorectal Surgery and Endoscopy Clinic top specialist surgeon Dr. Cheryl Lau, who specializes in gastrointestinal surgery, explained to CNA Women that the vast majority of obstetric-related fistulas are anovaginal fistulas. In developed countries, they are rare and occur in about 1 to 3 per 10, 000 sales.
Worldwide, there are an estimated 100, 000 instances of maternal fistulas per month, according to Professor Christopher Chong, a urogynaecologist, physician and gynaecologist at Gleneagles Hospital. But, he added that such cases are less frequent in Singapore and other developed countries.
WHO IS AT RISK
During childbirth, specific factors may increase the risk.
According to Prof. Chong, Asian women typically have a shorter skin, which is the baby’s head’s pelvic opening, and the vaginal opening is smaller.
The doctor makes a slice called episiotomy ( commonly away from the anus ),” according to the article” the baby head coming through the cervix typically causes tears. He claimed that this helps to reduce ragged and chaotic tears and depart the tear from the anus.
However, an obstetric fistula may also arise due to complications, such as delivering a large baby, a baby with a massive head, an acoustic delivery ( for example, use of forceps ), a very fast labour or a continuous one, or when the baby is delivered in a non-optimal position.
