The question whether transhiatal (TH) or transthoracic (TT) resection is most suited for the extirpation of an esophageal cancer remains unresolved. The present study compared the two approaches in a prospective randomized manner.
Thirty-nine patients with carcinoma of the lower third of the esophagus who were clinically fit for either TH or TT resection were prospectively randomized to TH (20 patients) and TT (19 patients) resection. Patients of the two groups were comparable in age, sex, preoperative tumor staging, and pulmonary and cardiac risks for surgery.
There was no significant difference in the amount of blood loss between the two groups although intraoperative hypotension (systolic <80 mm Hg) occurred more frequently in the TH group (P <0.001). The mean operating time for the TH and TT groups were 174 minutes and 210 minutes, respectively (P <0.001). There was no difference in postoperative ventilatory requirements, cardiopulmonary complication rates, and, mean hospital stay between the two groups. There was no 30-day mortality in either group but there were 3 hospital deaths in the TH group from bronchopneumonia (2 patients) and disseminated malignancy (1 patient). The median survival rates were 16 and 13.5 months, respectively, for the TH and TT groups (P = NS).
Although there was no demonstrable statistical difference in results between TH and TT approaches, the TT approach is preferred as it allowed for a more controlled operation.
经裂孔(TH)或经胸(TT)切除术哪种最适合食管癌切除的问题仍未解决。本研究以前瞻性随机方式比较了这两种手术方法。
39例食管下段癌患者,临床适合TH或TT切除术,被前瞻性随机分为TH组(20例)和TT组(19例)进行切除术。两组患者在年龄、性别、术前肿瘤分期以及手术的肺部和心脏风险方面具有可比性。
两组间失血量无显著差异,尽管TH组术中低血压(收缩压<80mmHg)发生频率更高(P<0.001)。TH组和TT组的平均手术时间分别为174分钟和210分钟(P<0.001)。两组术后通气需求、心肺并发症发生率及平均住院时间无差异。两组均无30天死亡率,但TH组有3例医院死亡,分别死于支气管肺炎(2例)和播散性恶性肿瘤(1例)。TH组和TT组的中位生存率分别为16个月和13.5个月(P=无显著性差异)。
虽然TH和TT两种手术方法的结果在统计学上无明显差异,但TT手术方法更受青睐,因为它能使手术操作更可控。
