Summary
The use of endoscopic submucosal dissection(ESD)for the treatment of duodenal tumors has increased recently. ESD is less invasive than surgical resection of duodenal tumors. However, a high rate of complication, including perforation and bleeding, has been reported to be associated with ESD. Here, we report the minimally invasive surgical procedure called“endoscopy guided single-incision laparoscopic partial duodenectomy”for the treatment of duodenal tumors, along with its and safety and treatment outcomes. Five patients were included in this study. We mounted the LAP PROTECTOR™ and EZ access® in the umbilical incision. Single-incision laparoscopic surgery was performed using 3 trocars(5 mm)that were placed into the EZ access®. First, we mobilized the duodenum and pancreatic head from the retroperitoneum using the laparoscopic“Kocher maneuver”. Next, the peritumoral site was marked by an endoscopic procedure using a clip and electric needle knife. Using an endoscope, we performed laparoscopic full-thickness resection of the duodenal wall including the tumor. The defect in the duodenal wall was then closed by suturing.
要旨
十二指腸腫瘍における内視鏡的治療は穿孔リスクが高いとされる。われわれが行っている低侵襲で安全な内視鏡併用単孔式腹腔鏡下十二指腸部分切除術の手術手技および手術成績を報告する。臍部創からの単孔式腹腔鏡下に十二指腸の剥離・授動を行う。内視鏡観察下に腫瘍周囲をマーキングし,腹腔鏡下に十二指腸の全層切除を行う。壁欠損部は体腔内で縫合閉鎖する。腹腔洗浄細胞診にて,腫瘍細胞散布の有無をモニタリングしている。これまでに本術式を5例(早期癌2例,腺腫3例)経験した。平均年齢63.2(51~72)歳,いずれも男性で,病変の局在は上十二指腸角1例,十二指腸下行脚4例,平均腫瘍径は15.2(8~25)mmであった。十二指腸壁欠損部は全例体腔内縫合にて閉鎖した。平均手術時間296(256~349)分,出血量9.5(3~20)mLであった。いずれも重篤な合併症なく安全に施行され,術後の平均在院日数は7.8(7~9)日,現時点で再発症例は認めていない。
