| Popis: | Introduction Precisely locating benign upper gastrointestinal tumors during laparoscopic-endoscopic surgery remains difficult and inaccurate. We describe reverse laser-supported diaphanoscopy (RLSD) for locating gastrointestinal tumors during laparoscopic surgery and present prospective evaluation results of the first cases. Materials and methods We studied 13 patients [women:men=7:6; mean age, 67 (range, 41 to 83) y] who underwent gastroscopic-laparoscopic rendezvous procedures during 2015 to 2018. Surgery duration, marking duration, and specimen resection size were recorded. The largest and smallest specimen resection margins were measured. Results After locating tumors using RLSD, patients underwent successful resections. Histopathologic examination confirmed 5 cases of gastrointestinal stromal tumor; 3, neuroendocrine tumors; 2, heterotopic pancreatic tissue; 1, leiomyoma; 1, adenoma; 1, hyperplastic polyp. We employed 4 to 6 marks, depending on tumor location and size. The average marking duration was 14 minute (1 to 21 min); the average surgery duration, 73 minute (37 to 143 min). The smallest resection median margin was 2.0 mm (1.0 to 5.0 mm); the largest, 7.0 mm (2.0 to 12.0 mm). Conclusions RLSD precisely locates gastric benign tumors during laparoscopic-endoscopic rendezvous procedures. |
