Abstract:
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.
