Combined uterine injury and high rectal perforation complicating abdominal ectopic pregnancy: A case report

Introduction and importance: Abdominal pregnancy is a rare and potentially fatal variant of ectopic pregnancy, presenting unique clinical challenges. This report discusses an unusual case of abdominal pregnancy associated with uterine and high rectal perforations, complications that are rarely reported in clinical practice. Case presentation: We report a case involving a 31-year-old woman from a rural area, with a psychiatric history, presenting severe abdominal pain, vomiting, and constipation. Initial investigations revealed a hemopneumoperitoneum and a fetal skeleton in the pelvic area by CT, leading to a diagnosis of abdominal pregnancy. Surgical findings included a nonviable fetus, approximately 5 months gestational age, and perforations in both the rectum and the posterior uterine wall. Clinical discussion: The patient underwent extensive surgery, including placental dissection, anterior rectal resection, Hartmann's colostomy, hysterorrhaphy, and drainage of the peritoneal cavity. The complexity of managing abdominal pregnancy, especially with additional complications such as organ perforations, poses significant surgical challenges. This case emphasizes the need to consider abdominal pregnancy in differential diagnoses of abdominal pain in women, due to the risk of misdiagnosis and complex surgical requirements. Conclusion: This case highlights the critical importance of prompt diagnosis and comprehensive care in managing rare and life-threatening presentations of abdominal pregnancy. It underscores the need to increase awareness among clinicians for timely intervention and provides information on the complexities of surgical management in cases with additional organ perforations.
