The widespread use of operative and diagnostic laparoscopy leads to growing use of laparoscopic ultrasound as a complementary procedure. A preliminary study was performed to evaluate the efficacy of laparoscopic ultrasound using a linear array laparoscopic probe characterised by double frequency, mechanical flexibility and availability of Doppler analysis. Twenty-five cases of cholecystolithiasis were evaluated during laparoscopic cholecystectomy in comparison with laparoscopic cholangiography: no differences were observed. Nine cases of gastrointestinal neoplasms (gastric, colon, pancreatic, and liver cancer) were evaluated in comparison with preoperative sonography and computed tomography. Laparoscopic sonography improves abdominal malignancy detection (cancer spread, lymph node metastasis, liver metastasis), thus modifying therapeutic decisions. The possibility of moving the probe in flexion extension movements allows a complete, multiplane exploration of operative fields. Laparoscopic sonography represents a complementary, indispensable diagnostic method during laparoscopic surgery.
手术及诊断性腹腔镜检查的广泛应用使得腹腔镜超声作为一种辅助检查手段的使用日益增多。本研究进行了初步评估，使用具有双频、机械灵活性及多普勒分析功能的线性阵列腹腔镜探头评估腹腔镜超声的疗效。在25例腹腔镜胆囊切除术治疗胆囊结石的病例中，将腹腔镜超声与腹腔镜胆管造影进行比较：未观察到差异。在9例胃肠道肿瘤（胃癌、结肠癌、胰腺癌和肝癌）病例中，将腹腔镜超声与术前超声及计算机断层扫描进行比较。腹腔镜超声可提高腹部恶性肿瘤的检测率（癌症扩散、淋巴结转移、肝转移），从而改变治疗决策。探头可进行屈伸运动，这使得能够对手术区域进行完整的多平面探查。腹腔镜超声是腹腔镜手术中一种辅助性的、不可或缺的诊断方法。
