RESUMO
INTRODUCTION: Conjoined twins are rare, high-stakes cases requiring complex management. This report presents thoraco-omphalopagus conjoined twins who shared parts of liver and abdominal wall. The main obstacle in separating these patients was liver fusion. PRESENTATION OF CASE: Two-year-old female conjoined twins presented with liver fusion between segments 2 and 3 in twin A and segments 2 and 4A in twin B. Liver separation was performed using the modified liver hanging maneuver. After separating the triangular ligaments and surrounding adhesions, a 12-Fr Foley catheter was inserted under the fused liver, suspending it upward and producing a clear separation plane. Liver separation required only 32 min. No notable bleeding or bile leakage was observed. DISCUSSION: The liver hanging maneuver was originally used as an adjunct technique for liver tumor hepatectomy. We used this technique to separate the fused livers in conjoined twins. The advantages of LHM include potentially reducing excess manipulation, which may result in parenchyma and vascular pedicle injury, and facilitating bleeding control, thereby reducing the operation time. CONCLUSION: The liver hanging maneuver using a conventional Foley catheter is a simple and useful method for separating fused livers in conjoined twins.
