Selection of patients for treatment of oesophagogastric cancers rests on accurate staging. Laparoscopy has become a safe and effective staging tool in upper gastrointestinal cancers because of its ability to detect small peritoneal and liver metastases missed by imaging techniques. The aim of this study was to evaluate the role of staging laparoscopy (SL) in determining resectability of oesophagogastric cancers.
A review of 511 patients with oesophagogastric cancers referred to our centre during a 7-year period was performed. Four hundred and sixteen of them assessed to have resectable tumours after preoperative staging with CT and/or ultrasound underwent SL. The main outcome measure was the number of patients in whom laparoscopy changed treatment decision.
Staging laparoscopy changed treatment decision in 84 cases (20.2%): locally advanced disease in 17, extensive lymph node disease in four and distant metastases (liver and peritoneum) in 63 cases. The sensitivity of laparoscopy for resectability was 88%. Eighty-one percent of patients who had combined CT scan and EUS were resectable at surgery compared with 65% of those who had CT scan alone (statistically significant with P-value<0.05). Of those patients deemed resectable by SL 8.1% were found to be unresectable at laparotomy, 16 with locally advanced disease and 11 with metastases.
Staging laparoscopy avoided unnecessary laparotomy in 20.2% of our patients and was most useful in adenocarcinoma, distal oesophageal, GOJ and gastric cancers and probably not necessary in lesions of the upper two-third of the oesophagus.
食管癌和胃癌患者的治疗选择取决于准确的分期。腹腔镜检查因其能够检测出影像学技术遗漏的小的腹膜和肝转移灶,已成为上消化道癌安全有效的分期工具。本研究的目的是评估分期腹腔镜检查(SL)在确定食管癌和胃癌可切除性方面的作用。
对7年间转诊至本中心的511例食管癌和胃癌患者进行回顾性研究。其中416例患者在术前经CT和/或超声分期评估为可切除肿瘤,接受了SL检查。主要观察指标是腹腔镜检查改变治疗决策的患者数量。
分期腹腔镜检查改变了84例(20.2%)患者的治疗决策:17例为局部晚期疾病,4例为广泛淋巴结疾病,63例为远处转移(肝脏和腹膜)。腹腔镜检查对可切除性的敏感性为88%。联合CT扫描和EUS检查的患者中81%在手术中可切除,而仅接受CT扫描的患者中这一比例为65%(P值<0.05,具有统计学意义)。在SL检查认为可切除的患者中,8.1%在剖腹手术中被发现不可切除,其中16例为局部晚期疾病患者,11例为有转移的患者。
分期腹腔镜检查使20.2%的患者避免了不必要的剖腹手术,对腺癌、远端食管癌、胃食管交界部癌和胃癌最为有用,而对食管上三分之二部位的病变可能没有必要。
