Pulmonary Edema Induced by Esophagectomy

Yusuke Sato; Satoru Motoyama; Junichi Ogawa

Esophageal cancer is the seventh leading cause of cancer deaths worldwide (410,000 new cases annually)(1). Asian, Middle Eastern, and East African countries have a markedly higher incidence of esophageal cancer than other areas. In the United States, the incidence of adenocarcinoma of the distal esophagus and gastroesophageal junction has progressively increased to approximately 70% of all esophageal cancers over the last two decades. It affects mostly Caucasian men, and its pathogenesis is linked to gastroesophageal reflux disease (GERD) and the development of Barrett’s esophagus. On the other hand, squamous cell carcinoma is responsible for 95% of all esophageal cancers worldwide. It arises from whole esophagus, from the cervical esophagus to the gastroesophageal junction, and spreads to the cervical, thoracic, and abdominal lymph nodes with relative ease because of the abundant and complex lymphatic network (2). Therefore, esophagectomy with extensive neck, thoracic, and abdominal lymph node dissection, the so-called “3-field lymph node dissection,” is needed for curative surgery for esophageal squamous cell carcinoma (3). Though chemotherapy, radiotherapy, and combination therapy of both have been substantially developed as treatments for esophageal squamous cell carcinoma in recent years, these treatments are still inferior in survival rate and late toxicity compared to surgery (4).

A Case of Surgery for Thoracic Esophageal Cancer with Acute Intermittent Porphiria

Yasuhiro Sasaki; Satoru Motoyama; Manabu Okuyama; Kiyotomi Maruyama; Junichi Ogawa

49歳の男性で, 人間ドックで食道癌を指摘された. 急性間欠性ポルフィリン症による腹痛発作の既往があった. 手術にあたって, 禁止薬剤を使用しない, 十分な輸液・ブドウ糖を補充することを中心とする対策をたて, 食道切除胃管再建術を施行した. 術中・術後を通して, 急性間欠性ポルフィリン症による症状は出現せず, 尿中ポルフィリン代謝産物も増加しなかった. 本邦で急性間欠性ポルフィリン症合併患者に対する手術例の報告は, 本症例を含めて7例のみであり, 食道切除再建術のような侵襲の大きい手術報告は初めてであった. 適切な管理により急性間欠性ポルフィリン症患者に対する手術が安全に行えることを経験した.

Kazuhiro Imai; Satoru Motoyama; Reijiro Saito; Manabu Okuyama; Hiroshi Imano; Taku Nakagawa; Masato Sageshima; Junichi Ogawa

症例は42歳の男性で, つかえ感を主訴に受診し, 上部消化管造影および内視鏡検査にて胸部中部食道に長径4cmの全周性狭窄を認めたが, 粘膜病変は見られなかった. CTで腫瘍は左主気管支, 下行大動脈に浸潤し, 悪性腫瘍が示唆された. 2度の消化管内視鏡下生検で確定診断をえられず, 胸腔鏡下腫瘍生検術を施行した. その結果, びまん性B細胞リンパ腫と診断された. 化学 (CHOP療法) および放射線 (40Gy) 療法を施行し, 完全寛解をえた. 治療後3年経過したが, 再発を認めていない. 確定病理診断の下, 化学放射線療法で3年の完全寛解をえた食道原発悪性リンパ腫の1例を報告した.
