New marking method involving a light-emitting diode and power source device to localize gastrointestinal cancer in laparoscopic surgery

Abstract

Although the preoperative endoscopic marking method using dye is widely used, the dye can spread into the tissue or abdominal cavity, inducing the inflammation and leading to the wrong dissection. We developed a novel marking method using an endoscopic clip with a light emitting diode (LED) and a power source device to detect the accurate location of the site of interest. We performed this new marking method in three patients with gastrointestinal cancers. We placed an endoscopic clip with an LED on the gastrointestinal mucosa and used a power source device outside of the human body to detect the LED. We detected the clip with the LED using the power source device. We also confirmed the usefulness of this clip in three of three (100%) patients with colorectal and gastric cancer. We developed a novel marking device using an LED to identify an objective location successfully.

Innovative marking method using novel endoscopic clip equipped with fluorescent resin to locate gastric cancer

“…Endoscopic tattooing of the submucosa of the stomach and intraoperative endoscopy are the conventional methods for the locating gastric lesions during laparoscopic surgery for gastric cancer 1,4 . However, faint and diffuse tattooing may lead to difficulties in recognizing the cancer site, and intraoperative endoscopy may require additional human power and an extended operatve time 6 …”

“…Several marking techniques to create a precise resection line during laparoscopic surgery have been reported, including an endoscopic clip with a light‐emitting diode, 6 endoclips with radio frequency identification, 7 and endoscopic ICG tattooing injected into the submucosal layer of the gastric wall. 4 However, all these techniques have limitations such as the need for a power source and the possibility of electromagnetic interference.…”

“…MISs have been widely adopted in various fields of surgery with rapid developments [2]- [4]. Particularly, laparoscopic surgeries, one of the MISs, have been applied for gastrointestinal surgeries and have advanced with the development of various surgical instruments [5], [6].

“…Although laparoscopic surgeries are beneficial to patients, there are some challenges. One of the main challenges is that it is difficult for the surgeon to localize the small lesion, such as early cancer because they cannot palpate the organ [5]. If the lesion is inaccurately localized, a further laparotomy is necessary to resect the remaining lesion [10].…”
