Colonoscopy is the standard of care for screening and surveillance of colorectal cancers. Removal of adenomatous polyps prevents the transformation of adenomas to potential adenocarcinoma. While most polyps are amenable to simple endoscopic polypectomy, difficult polyps that are large, broad-based, or located in haustral folds or in tortuous colon segments can present a challenge for endoscopists. Traditionally, patients with endoscopically unresectable polyps have been referred for oncologic surgical resection due to the underlying risk of malignancy within the polyp; however, the majority of these polyps are benign on final pathology. Combined endoscopic laparoscopic surgery can help facilitate endoscopic removal of difficult lesions, or allow the surgeon to select the correct laparoscopic approach for polyp excision. Current literature suggests that these procedures are safe and effective and can potentially save patients from the morbidity of laparotomy and segmental colectomy.
结肠镜检查是结直肠癌筛查和监测的标准治疗方法。切除腺瘤性息肉可防止腺瘤转变为潜在的腺癌。虽然大多数息肉适合简单的内镜下息肉切除术,但大的、基底较宽的、位于结肠袋皱襞或迂曲结肠段的困难息肉可能给内镜医师带来挑战。传统上,内镜下无法切除息肉的患者由于息肉存在潜在恶性风险而被转诊进行肿瘤外科切除;然而,这些息肉中的大多数最终病理结果为良性。内镜联合腹腔镜手术有助于促进内镜下切除困难病变,或使外科医生能够选择正确的腹腔镜息肉切除方法。目前的文献表明,这些手术是安全有效的,有可能使患者避免剖腹手术和节段性结肠切除术的并发症。
