On the evening of November 29, 2012, a patient with ectopic pregnancy in a rare site was successfully rescued. With the attention of hospital leaders, full coordination of functional departments, collaboration of obstetrics and gynecology specialists, surgical specialists, ultrasound doctors and anesthesiologists, the embryonic tissue located in the anterior wall of the patient’s rectum was successfully removed. Ectopic pregnancy, commonly known as ectopic pregnancy, is a pregnancy in which the embryo is bedded outside the uterine cavity and develops. Because ovulation usually occurs in the ovaries and fertilization is done in the fallopian tubes, ectopic pregnancy is commonly seen in the fallopian tubes. Therefore, tubal and ovarian pregnancies are common, while the incidence of abdominal pregnancy is only 1 in 15,000, and the site of abdominal pregnancy is mostly the intra-abdominal organs such as the greater omentum and peritoneal surface. In this patient, the pregnancy tissue was located outside the abdominal cavity, in the right anterior wall of the retroperitoneal rectum, only 5 cm from the anus and 2 mm from the rectal mucosa, a 3 cm mass with a small heart pounding. For such a rare case and such a difficult condition, the treatment plan was clear: the embryo had to be removed because it was alive, the villi had erosive function, and if it grew any longer, it might rupture and hemorrhage as well as penetrate the intestinal canal. Although found in time, removal was extremely difficult, too high from below, too deep from above, and with the risk of damage to the intestinal canal and the risk of a rectal fistula. The decision was difficult. The specialists knew the difficulties and eventually, with the understanding and cooperation of the family, the difficulties were solved and the embryonic tissue was successfully removed with little bleeding and the intestinal canal was temporarily safe. On the second day after the operation, the patient’s blood value dropped from nearly 12,000 before the operation to 3,000; on the third day after the operation, the patient’s body temperature returned to normal, he had farting and a liquid diet; one week after the operation, the abdominal drainage tube was removed and he had a bowel movement. At this point, all those who were worried about this were relieved that the intestinal tube was completely safe!
