Schwannomas are benign tumors that arise from neural sheath Schwann cells. Solitary benign schwannoma is generally located in the head and neck and is a rare neoplasm among the tumors of the retroperitoneal space. Reports of laparoscopic excision of retroperitoneal schwannomas have recently been on the increase. However, few cases of single-port laparoscopic excision of these tumors have been reported. Moreover, there are no reports of single-port excision of schwannomas attached to the body of pancreas and around the splenic vessels. This is the first report of a schwannoma lying adjacent to the body of the pancreas between the splenic artery and vein that was excised by single-port laparoscopic surgery. The most notable aspect of our procedure is the use of bipolar forceps. Single-port laparoscopic excision using bipolar forceps is a feasible and safe procedure for retroperitoneal solitary tumors, even when they are close to the splenic artery and vein.
神经鞘瘤是起源于神经鞘雪旺细胞的良性肿瘤。孤立性良性神经鞘瘤通常位于头颈部，在腹膜后间隙肿瘤中是一种罕见的肿瘤。最近，关于腹腔镜切除腹膜后神经鞘瘤的报道不断增加。然而，单孔腹腔镜切除这些肿瘤的病例报道很少。此外，尚无关于附着于胰体和脾血管周围的神经鞘瘤单孔切除的报道。本文首次报道了通过单孔腹腔镜手术切除位于脾动脉和静脉之间、毗邻胰体的神经鞘瘤。我们手术最显著的特点是使用了双极电镊。即使腹膜后孤立性肿瘤靠近脾动脉和静脉，使用双极电镊进行单孔腹腔镜切除也是一种可行且安全的手术方法。
