Accurate preoperative staging of gastrointestinal malignancies is of major importance in the decision for adequate stage-related therapy. There is evidence that laparoscopy in combination with laparoscopic ultrasound is more accurate in the detection of intra-abdominal metastases than conventional preoperative imaging. Staging laparoscopy in combination with laparoscopic ultrasound is a minimally invasive technique that reveals intra-abdominal disseminated tumor spread and local tumor extent. Therefore laparoscopic ultrasound is an ideal adjunct to laparoscopy because this technique may compensate for the lack of tactile feedback with laparoscopic instruments. Color-coded Doppler imaging can be very valuable for the assessment of resectability in patients with pancreatic cancer. Current data confirm that laparoscopic ultrasound is capable of enhancing the accuracy of staging laparoscopy. Compared to standard laparoscopy, a combination of both techniques markedly increases the sensitivity of staging laparoscopy in the determination of unresectable disease. This is of major importance in the assessment of occult liver metastases and lymph node involvement. Laparoscopic ultrasonography improves the diagnostic accuracy compared to conventional imaging techniques and should be considered as integral part of staging laparoscopy.
胃肠道恶性肿瘤的准确术前分期对于决定适当的分期相关治疗至关重要。有证据表明，腹腔镜联合腹腔镜超声在检测腹腔内转移方面比传统术前影像学检查更准确。分期腹腔镜联合腹腔镜超声是一种微创技术，可揭示腹腔内播散性肿瘤扩散和局部肿瘤范围。因此，腹腔镜超声是腹腔镜的理想辅助手段，因为该技术可弥补腹腔镜器械缺乏触觉反馈的不足。彩色编码多普勒成像对于评估胰腺癌患者的可切除性可能非常有价值。目前的数据证实，腹腔镜超声能够提高分期腹腔镜检查的准确性。与标准腹腔镜检查相比，两种技术的联合显著提高了分期腹腔镜检查在确定不可切除疾病方面的敏感性。这在评估隐匿性肝转移和淋巴结受累方面至关重要。与传统成像技术相比，腹腔镜超声检查提高了诊断准确性，应被视为分期腹腔镜检查的组成部分。
