消化道恶性肿瘤主要治疗方法为手术切除。虽然Ｂ超、ＣＴ、磁共振(ＭＲＩ)及血管造影等先进诊断方法广泛应用,但消化道恶性肿瘤的可切除性术前仍难确定,需手术探查后才能决定。我们将腹腔镜用于剖腹探查术前检查,以探讨腹腔镜对判断消化道恶性肿瘤可切除性的作用。现报告如下。 The main treatment for malignant tumors of the digestive tract is surgical resection. Although advanced diagnostic methods such as B-ultrasonography, CT, magnetic resonance imaging (MRI), and angiography are widely used, the resection of malignant tumors of the digestive tract is still difficult to determine before surgery and can only be determined after surgical exploration. We will use laparoscopy for preoperative examination of laparotomy to investigate the role of laparoscopy in determining the resectable nature of digestive tract malignancy. The report is as follows.
