Laparoscopic hysterectomy as optimal approach for 5400 grams uterus with associated polycythemia: A case report

Myomatous erythrocytosis syndrome: A case report

BACKGROUND

Uterine myoma is the most common benign tumor among women and is often accompanied by anemia. Here, we report the case of a patient with a very large leiomyoma but with a hemoglobin level as high as 197 g/L. After undergoing hysterectomy, all her hematological parameters returned to normal. Immunohistochemical staining of her myoma for erythropoietin showed strong positivity, which suggested that erythropoietin may be the cause of her erythrocytosis. A multidisciplinary team played a significant role in treating the disease.

CASE SUMMARY

A 47-year-old woman visited our department complaining that her abdomen had been continuously growing for the past 2 years. After careful examinations, she was suspected of having a very large leiomyoma. She was also diagnosed with erythrocytosis because her RBC count was 6.49 × 10¹²/L, hemoglobin was 197 g/L. Following a multidisciplinary team consultation, bilateral ureteral stents were placed, and 800 mL blood was removed by phlebotomy. The patient then underwent hysterectomy and bilateral salpingectomy. She recovered well from the operation, and her hemoglobin level decreased sharply following the surgery. Low-molecular-weight heparin was administered daily to prevent postoperative thrombosis. She was discharged from the hospital on the fourth postoperative day. Two months later, all her hematological parameters returned to normal. Pathological analysis of the myoma revealed that it was a benign leiomyoma, with partial hyalinization, and strong positivity for erythropoietin in immunohistochemical staining suggested that erythropoietin may be responsible for the erythrocytosis.

CONCLUSION

Erythropoietin ectopically produced from the myoma was responsible for the erythrocytosis in this patient. A multidisciplinary team is strongly recommended.

Feasibility and safety of total laparoscopic hysterectomy for uteri weighing from 1.5 kg to 11.000 kg

PURPOSE

To assess the feasibility and safety of total laparoscopic hysterectomy (TLH) for uteri ≥ 1.5 kg.

METHODS

We prospectively evaluated all elective TLHs (with or without adnexectomy) performed for fibromatous uteri between August 2009 and August 2019 in the Department of Obstetrics and Gynecology, Sirai Hospital, Carbonia, and the Department of Gynecologic Oncology, Businco Hospital, Azienda Ospedaliera Brotzu, Cagliari. Patients with large myomatous uteri (uterine weight ≥ 1.5 kg on pathology reports) were included in the analysis. We examined all procedures and collected data about intra- and post-operative short-term and long-term complications, intraoperative blood loss, operative time, hospital stay, and time to achieve well-being.

RESULTS

Seventy-eight patients were included. The median weight was 2,000 g (range 1,500-11,000 g), estimated blood loss was 100 mL (range 10-700 mL), operating time was 135 min (range 60-300 min), and hospital stay was 2 days (range 2-5 days). Conversion to laparotomy occurred in 4 patients (5.1%) with uterine weight ranging from 3 to 5.5 kg, due to severe adherence syndrome or inadequate visualization. As for intraoperative complications, 1 patient (who had the largest removed uterus weighing 11,000 g) experienced an intraoperative ureteral injury (grade III). No major postoperative complications occurred.

CONCLUSIONS

This study provides the largest case series of TLH for fibromatous uteri > 1.5 kg and includes some of the largest uteri reported to date in the literature (weighing 5,320, 5,720, and 11,000 g, respectively). The study reaffirms the feasibility and safety of a minimally invasive hysterectomy even in the case of abnormally large uteri.

Laparoscopic management of a giant mucinous benign ovarian mass weighing 10150 grams: A case report

BACKGROUND

Giant ovarian cysts (≥ 15 cm in diameter) are rare. The size limit of cysts and the methodology for a safe and successful minimally invasive surgery has not been established. Here we report a case of a large 10-kg multi-locular ovarian mass, which was successfully laparoscopically removed: Our aim was to innovate the surgical practice in this field by providing a safe, effective, and minimally invasive management method for such complex and rare cases.

CASE SUMMARY

A 49-year-old nulliparous woman presented with abdominal distension, lasting from six Mo prior to admission; she reported worsening abdominal pain, abdominal swelling, and mild dyspnea. Imaging showed a presumed benign multi-locular (> 10 locules) left ovarian cyst that measured about 30 cm in diameter. Based on the IOTA-ADNEX model the mass had a 27.5% risk of being a borderline or malignant tumor. The patient was successfully treated via a direct laparoscopic approach with salpingo-oophorectomy, followed by the external drainage of the cyst. Tumor spillage was successfully avoided during this procedure. The final volume of the drained mucinous content was 8950 L; the cyst wall, extracted through the minilaparotomy, weighed about 1200 g. The pathologic gross examination revealed a 24 cm × 15 cm × 10 cm mass; the histologic examination diagnosed a mucinous cystoadenoma. To our knowledge, this is the first case of a giant multi-locular ovarian cyst treated with a direct laparoscopy with salpingo-oophorectomy followed by external decompression.

CONCLUSION

Choosing the appropriate technique and surgeon skill are necessary for a safe and effective minimally-invasive approach of unique cases involving giant ovarian cysts.
