Postcoital vaginoperitoneal fistula after hysterectomy for gynecological malignancy

A true incidence of postcoital fistula is not known as it is seldom suspected. It presents as acute pneumoperitoneum with signs and symptoms same as that of perforation of a hollow viscus. A 38-year-old parous woman presented with postcoital fistula 10 weeks after panhysterectomy for carcinoma ovary stage IIIc. Pneumoperitoneum was detected, with large amount of gas under the diaphragm on radiograph of the abdomen. A breach was found in the vaginal vault. All other causes of fistula were excluded. Fistula healed spontaneously on follow-up.
