“…Meanwhile, ESD has a higher complication risk [28], and open surgery has a potential of higher morbidity and mortality [29]. To resolve these problems, a minimally invasive surgery for NAD-NETs, such as laparoscopic and endoscopic cooperative surgery and endoscopy-assisted laparoscopic full-thickness resection, has been recently reported [30,31,32]. These new procedures are likely to be safe and feasible for NAD-NETs in the anterior wall of the first and second portion of the duodenum.…”

Background/Aims: The treatment strategy for non-ampullary duodenal neuroendocrine tumors (NAD-NETs) ≤20 mm in diameter has not been established. In this study, we aimed to evaluate the detailed characteristics of NAD-NETs ≤20 mm in diameter to clarify the risk factors of subsequent metastasis. Methods: The patients with NAD-NETs ≤20 mm in diameter who had been treated at 12 institutions between 1992 and 2013 were enrolled. Clinical records were retrieved, and histopathological findings of all cases were centrally reviewed by 2 pathologists. Results: We studied 49 patients with a mean follow-up period of 66.5 months. Thirty-five patients were initially treated with endoscopic resection (ER), and 14 with surgery. A univariate analysis revealed the ORs and 95% CIs of the risk factors for metastasis were lymphovascular invasion (12.5 [2.01-77.9]), multiple tumors (9.75 [1.46-65.4]), a tumor size of 11-20 mm (6.67 [1.21-36.6]), and World Health Organization grade G2 (7.13 [1.16-43.9]). Five-year overall and disease-specific survival rates were 86.1 and 97.2%, respectively. Conclusion: This is the first study to demonstrate the risk factors of metastasis in NAD-NETs ≤20 mm in diameter. These findings may be helpful for determining the appropriate therapeutic approach and the clinical strategy of treatment following ER.

“…Although there have been many articles about the use of LECS for gastric lesions, only six cases have been previously reported for duodenal tumors: two adenomas, one gastrointestinal stromal tumor (GIST), and three neuroendocrine tumors (NET) located in the first or second portion of the duodenum [4] . This is the first case of primary adenocarcinoma in the D3 that was successfully resected by LECS.…”

“…In recent years, the increased use of endoscopies has led to an increased identification of duodenal tumors [2] ; however, a neoplasm in the third or fourth portion of the duodenum is an extremely rare entity and is sometimes difficult to treat [3] . Endoscopic treatment is generally appropriate for dysplastic polyps or intramucosal adenocarcinomas, although some cases may be difficult to resect endoscopically because of the thinness of the duodenal wall and the narrow working space [4] . We report a case of primary adenocarcinoma of the third portion of the duodenum (D3), resected curatively using the laparoscopic and endoscopic cooperating surgery (LECS) technique.…”

Endoscopic full-thickness resection (EFTR) is a procedure that makes it possible to access the lesions that are on the wall of the digestive tract via the shortest distance through the mouth. Because of the ultra-minimal invasive nature of the treatment, pure EFTR is a highly promising surgical procedure that allows the radical excision of full-thickness layers of digestive tract tumors using only a flexible endoscope. There are 2 types of EFTR methods: exposed and non-exposed. Considering the risks of contracting infection and intraperitoneal dissemination of tumor cells, non-exposed EFTR is an ideal method. However, a number of issues remain unresolved, including the method for performing a full-thickness suture under endoscopic view and the challenge of securing the operating field in the case of gastrointestinal tract collapse. Moreover, advances in the development of equipment such as full-thickness suturing devices would be helpful to make this therapeutic procedure the most minimally invasive endoscopic surgery ever.
