Abstract

We have applied two different laparoscopic surgical techniques for early gastric cancer and have successfully treated 111 patients since March 1992. The indications are: 1) preoperative diagnosis of mucosal cancer; 2) lesion size of < 25 mm if the protruding type; and 3) lesion size < 15 mm and UI (-) if the depressed type. The first technique is laparoscopic wedge resection of the stomach using a lesion-lifting method (n = 93). The gastric wall around the cancerous lesion is exposed laparoscopically. The abdominal wall and gastric wall in the vicinity of the lesion are pierced using a 12-G sheathed needle. A small metal rod with a fine wire is introduced into the stomach through the outer sheath. By retracting the metal rod, the lesion can be lifted precisely (i.e., lesion-lifting method). Wedge resection at a sufficient distance from the metal rod is carried out using an endoscopic stapler. The second technique is referred to as laparoscopic intragastric mucosal resection (n = 18). Three balloon trocars are placed in the stomach laparoscopically. The stomach is then insufflated with CO2, and surgical instruments are introduced. The mucosal and submucosal layers around the lesion are resected with sufficient surgical margins. The selection of the laparoscopic technique depends on the site of the cancerous lesion. In our series of 111 patients, sufficient horizontal (mean 15 +/- 5 mm and 8 +/- 4 mm, respectively, using the first and second technique) and vertical surgical margins were achieved. There was no mortality and no major complications in patients undergoing either surgical technique. There have been two recurrences, both mucosal lesions found 2 years after the initial surgery, which were successfully treated with gastrectomy and laser irradiation. All patients have survived for 3 to 96 months, and there has been no trocar site recurrence. In conclusion, these laparoscopic procedures are curative and minimally invasive treatments for early gastric cancer.
