Patients with colorectal or pancreatic cancers may have peritoneal implants which are too small to be detected by current radiologic imaging techniques. Since such implants often preclude surgical removal of the primary tumor or isolated metastasis, their detection prior to open abdominal exploration may spare patients the morbidity of a large abdominal incision when there is no benefit to resection and lifespan is limited.
In the past 30 months, patients with pancreatic cancer, hepatoma, or isolated colorectal cancer metastases, who were candidates for surgical resection on the basis of standard radiologic scans, were examined with the laparoscope through a 10-mm periumbilical incision prior to undertaking open abdominal exploration. If unexpected implants were noted, biopsy was obtained through a 5-mm port placed through a convenient site.
Since January 1993, 11 patients with pancreatic carcinoma, three patients with primary hepatic malignancies, and 12 patients with isolated metastases from colorectal cancers have undergone laparoscopic examination prior to celiotomy. Eight of these patients had unexpected peritoneal or liver involvement which precluded resection. Laparoscopy was successful in detecting disease in six such patients (75%).
Although adding 20-30 min to the operative time when unrevealing, laparoscopy provided an effective way to avoid celiotomy in patients with carcinomatosis.
结直肠癌或胰腺癌患者可能有腹膜种植转移灶,其体积过小,目前的放射影像学技术难以检测到。由于此类种植转移灶常常使原发性肿瘤或孤立转移灶无法通过手术切除,在进行开腹探查之前检测到它们,对于那些切除并无益处且生存期有限的患者而言,可避免因大的腹部切口而带来的并发症。
在过去30个月里,对于那些根据标准放射学扫描结果适合手术切除的胰腺癌、肝癌或孤立性结直肠癌转移患者,在进行开腹探查之前,先通过脐周一个10毫米的切口插入腹腔镜进行检查。如果发现意外的种植转移灶,则通过一个放置在方便位置的5毫米穿刺孔获取活检标本。
自1993年1月以来,11例胰腺癌患者、3例原发性肝癌患者以及12例孤立性结直肠癌转移患者在剖腹手术前接受了腹腔镜检查。其中8例患者有意外的腹膜或肝脏受累,无法进行切除。腹腔镜检查成功检测出6例此类患者的病情(75%)。
尽管在未发现病变时会使手术时间延长20 - 30分钟,但腹腔镜检查为避免对有癌性腹膜炎的患者进行剖腹手术提供了一种有效的方法。
