要旨 筆者らは食道SM癌に対する外科治療として胸腔鏡補助下食道切除術を施行している.2005~2010年までに胸腔鏡補助下食道切除術を78例に対して施行し,平均手術時間は529分,出血量は152ml,リンパ節郭清個数は35個であった.合併症は39.7%で,その内訳は反回神経麻痺6.4%,肺炎6.4%,縫合不全17.9%,創感染1.3%,膿胸5.1%,乳び胸2.6%であった.術死はなく,在院死は2例(2.6%)であった.平均ICU滞在日数は2.0日,在院日数は22.0日であった.pT1b-SM癌は36例で,5年生存率は78.6%であった.胸腔鏡補助下食道切除は術後合併症,長期予後などの手術成績も良好であり,安全かつ確実な治療法である.
Seventy-eight patients with esophageal carcinoma underwent thoracoscopic esophagectomy in our institution during the period of 2005 to 2010. Average duration of surgery was 529min, estimated blood loss was 152ml, and the number of dissected and retrieved lymph node was 35. Postoperative complications occurred in 31 patients(39.7%). The overall mortality rate was 2.6%. The average length of the intensive care unit stay days were 2days and the hospital stay days were 22.0days. There were 36 patients for pT1b-SM cancer, and the overall 5-year survival rate was 78.6%. Thoracoscopic esophagectomy is technically safe and feasible.
