Laparoscopic two-step abdomino-parasacral resection of a giant pelvic lipoma: a case report.

Background: Pelvic lipomas, particularly when massive in size, present unique surgical challenges due to their intricate anatomical location and proximity to vital structures. Complete resection of tumor is the basic principle. In this case, we demonstrated the complete resection of a huge pelvic lipoma by laparoscopy combined with a transsacral approach, which was rarely reported in the relevant literature. According to our case, a two-step abdomino-parasacral approach provides more flexibility, but also a safe and easier dissection in deep pelvic. Case Description: A 74-year-old female presented to the outpatient clinic, complaining of abdominal distension and difficulty in defecation for over 6 months. The patient had no obvious concomitant symptoms and she had a history of hypertension. After completing the relevant tests, the patient was diagnosed with a pelvic tumor, possibly a lipoma. We performed a two-step abdomino-parasacral approach to remove the tumor and the tumor was confirmed as lipoma. There was no tumor recurrence sign after 7 months follow-up for the patient. Conclusions: A two-step abdomino-parasacral resection of the lipomatous tumor were advantageous to manage
