Popis: Intraluminal surgery began with the advent of endoscopy. Endoscopic endoluminal surgery has limitations; and its failure results in conventional open or laparoscopic interventions with increased morbidity. Laparoscopy-assisted intraluminal surgery is a novel alternative to open or laparoscopic surgery for a failed endoscopic endoluminal technique, minimizing the associated complications. Endoscopic resection of early gastric and duodenal cancers is restricted by the limited view of the endoscope, insufficient number of instrument channels, and inability to have adequate margins of resection without risking perforation. These cancers potentially can be treated by laparoscopy-assisted intraluminal surgery without resorting to major gastric or duodenal resection. This procedure is relatively easy to perform and oncologically effective. We present the experience of the Texas Endosurgery Institute (TEI) in treating early gastric and duodenal cancers, including large malignant polyps and carcinoid tumors, with laparoscopy-assisted endoluminal surgery.The data for all patients with early gastric and duodenal cancers who underwent laparoscopy-assisted endoluminal surgery at TEI between 1996 and 2007 were prospectively recorded. All of the patients had been referred by the endoscopist as noncandidates for endoscopic resection. We prospectively collected data on preoperative diagnosis, operating time, estimated blood loss, postoperative complications, histopathology, and recurrence rate. All patients underwent endoluminal port placement under direct visualization after a pneumoperitoneum was established. Operations were performed in conjunction with upper endoscopy for assistance with port placement under endoluminal visualization, insufflation, and specimen retrieval. After the intraluminal portion of the operation was completed, the endoluminal port sites were closed with laparoscopic intracorporeal suturing.From 1996 to 2007, a total of 12 patients underwent laparoscopic endoluminal surgery. All cases were completed successfully, including 5 resections of early gastric cancer (stage I), 3 wedge resections of carcinoid tumor, 2 resections of duodenal adenocarcinoma, and 2 resections of a malignant polyp at the gastroesophagic junction; all the cases were completed with disease-free margins. No recurrence of the original pathology have been reported, and the complications were minimal.Laparoscopic intraluminal surgery for early gastric and duodenal cancer is a feasible alternative to open conventional therapies; and it is associated with a lower incidence of incisional hernia formation and a lower infection rate.
