Abstract:

Reduced port surgery (RPS) is a new surgical modality producing increased cosmetic benefits over conventional endoscopic surgery. We herein report the first case of insulinoma of the pancreas treated by RPS. RPS enucleation was performed for a 23-year-old Japanese female who was admitted to our hospital with repeated episodes of hypoglycemia attributable to an insulinoma. The preoperative examinations confirmed the diagnosis of a solitary insulinoma of the pancreatic tail. Enucleation of the insulinoma using RPS was performed. A 2.5-cm umbilical incision was made, and three laparoscopic trocars were individually inserted into the abdominal cavity via this incision. Another 3-mm trocar was inserted from the left subcostal region. All procedures that were usually performed in conventional laparoscopic surgery were also performed by RPS: intraoperative ultrasonography, mobilization of the tail of the pancreas, enucleation of the tumor, and suturing of the stump. A mechanical manipulator, the Radius Surgical System (Radius), was used for suturing and ligation. The Radius was sufficient to overcome in-line viewing and hand/instrument collisions, and enabled us to perform precise suturing and ligation. Serial blood sugar, C-peptide immunoreactivity (CPR), and immunoreactive insulin (IRI) measurements revealed that all values were normal after resection. The patient had an uneventful postoperative course. RPS was successfully applied for enucleation of a solitary mass in the tail of the pancreas, and represents an alternative to conventional laparoscopic surgery. This method is technically feasible and results in superior cosmesis. The Radius facilitated advanced laparoscopic surgery and may also have advantages in RPS.
