ドームポートを用いた単孔式腹腔鏡下回盲部切除術の有効性と安全性：症例報告

This is the first case report of single-incision laparoscopic surgery using the Dome Port for colon cancer. Dome Port is designed to enhance the operability and safety of single-incision surgery. The key advantages are as follows. First, this device is made of transparent silicone, allowing the surgeon to directly visualize the insertion of surgical instruments. Second, the flexible silicone material minimizes interference between surgical instruments and the port.

A 70-year-old female visited our hospital with occult blood test positive. She underwent a myoma resection approximately 20 years ago. A lower midline abdominal incision was present. Preoperative examination revealed the presence of advanced tumor in the cecum colon. Ileocecal resection was performed as the laparoscopic single-port technique using Dome Port. The procedure was performed safely, with an operation time of 138 min. The patient experienced minimal postoperative pain and resumed oral intake on postoperative day 2. The patient was discharged on postoperative day 6 without major complications.

The Dome Port's transparent silicone construction allowed direct visualization of instrument insertion, enhancing procedural safety, while its flexible material minimized instrument interference and improved ergonomic manipulation. Compared to conventional single-incision ports, these features may reduce operative difficulty and the risk of instrument collisions, potentially contributing to smoother workflows and lower complication rates.

The Dome Port was effective for single-incision laparoscopic ileocecal resection and may facilitate safer surgical procedures. It is expected to become one of the options for future reduced port surgery.
