- Abstract:
- Objective To explore the prenatal ultrasonography and surgical approaches of 7 cases of retroperitoneal fetus-in-fetu (FIF) and evaluate the clinical efficacy and review the literature.Methods From November 2016 to November 2019, 7 cases of retroperitoneal FIF were reviewed for collecting the relevant clinical data, including gender, age, prenatal ultrasonography, parasitic site, parasitic fetus number, surgical approaches, pre/postoperative value of alpha-fetoprotein (AFP), concurrent diseases and pathological examinations.Using such keywords as "parasitic fetus", "fetus-in-fetu" or "parasite twin", the authors searched the databases of CNKI, WanFang and PubMed for collecting the relevant literatures from 2010 to 2020 and summarizing the clinical data of FIF infants.Results There were 4 boys (57.14%) and 3 girls (42.86%).All cases were detected by prenatal ultrasonography (n=7, 100%).Surgical approaches were open operation (n=5, 71.43%) and mini-invasive surgery (n=2, 28.57%).There were twin FIF (n=2, 28.57%), merging Merkel’s diverticulum (n=1, 14.29%) and merging teratoma (n=1, 14.29%).One case was readmitted for peritoneal effusion (14.29%).There was no mortality.A total of 144 cases were collected through literature retrieval, including 63 males (43.75%), 69 females (47.92%) and 12 non-specified genders (8.33%).Forty-eight cases (33.33%) were detected by prenatal ultrasonography.There were traditional surgery (n=134, 93.06%) and laparoscopic-assisted surgery (n=2, 1.39%).Two FIF (n=8, 5.56%) and three FIF (n=2, 1.39%) were found.There were induced labor (n=4, 2.78%) and mortality (n=8, 5.56%).Conclusion Prenatal ultrasound may be employed as a screening tool for FIF.With an advancing gestational age, spinal column, long bone and umbilical cord-like vascular structure are detected.With an excellent prognosis, mini-invasive surgery for FIF has a faster recovery than traditional open surgery.
