大腸癌肝転移切除26例の残肝再発に関与する因子につき検討した.性別による差はみられなかったが, 年齢的には61歳以上の高齢者は60歳以下のものより残肝再発率が低かった.直腸癌の方が結腸癌より残肝再発率が高い傾向がみられたが, 肝転移巣の長径, 個数, 分化度では残肝再発率に差はみられなかった.同時性転移と異時性転移でも差はみられず, また, 一期的切除と二期的切除の間にも差はみられなかった.しかし, 術式において, 部分切除例の残肝再発率は4/7 (57.1%) であったのに対し, 広範囲切除例のそれは4/19 (21.1%) と低く, 術式の差が残肝再発率に関与することが示唆された

1968年から1987年までに経験した同時性肝転移58例を, 原発巣の占居部位別に検討した.肝転移率はS状結腸癌 (27.0%) と盲腸癌 (26.9%) に高く, 肝転移の個数は孤立性が22.4%, 多発性が77.6%であったが, 占居部位による個数には差はなかった.壁深達度別にみた肝転移率では, S状結腸癌と盲腸癌が深達度のすすんだもので直腸癌より高かったが, これらの病悩期間をみると前二者は直腸癌よりむしろ短かった.門脈血流に一定の法則があるとするstream line phenomenaを原発巣と肝転移巣の占居部位の上から検討したが, S状結腸癌は直腸癌より右葉へ転移しやすく, 逆に左葉へは転移しにくく, 盲腸癌は右葉へ転移しやすかった.

Clinical feature and management of early cancer of the large bowel with submucosal invasion.

Osamu Nishida; Hideya Isai; Naoki Sato; Hiroshi Shiroto; Fumio Sano; Junichi Uchino

1971年から1985年までに当科で経験した大腸sm癌15例に検討を加えた. 初発症状は血便が53%と最も多く, 占居部位ではS状結腸以下の下部大腸が73%を占めていた. 肉眼形態はIp, Is型が全体の86%を占めており, 腫瘍の最大径は2cm代のものが33%と最も多かった. 病理組織学的には高分化腺癌9例, 中分化腺癌6例であり, 脈管侵襲はly (+) が2例, v (+) が1例にみられた. 15例中n1 (+) が2例, 異時性肝転移が1例あり, これらのrisk factorは術前にかならずしも予測しえないものもある. したがって, その治療に際しては進行癌に準じた一次リンパ節の郭清をともなう腸管の切除が必要と考える.

In the advanced carcinoma of the digestive organs, the local recurrence is a major problem in surgery. We have applied a laser irradiation to the area after lymph node dissection in the surgery for the carcinoma of the GI tract and to the raw surface of the liver after hepatic resection. Experimental study demonstrated that the laser surgery have an advantage to prevent the local recurrence. Of 133 patient undergoing the laser surgery, ten patients underwent the laser irradiation and none of these developed the local recurrence so far after 4 years in the longest-term follow up. 47 patients underwent hepatic resection using a laser knife and proved to be a good prognosis. Postoperative prognosis although enough estimation can not be made is preliminarily favolable as a whole.
