“…Subsequently, we performed endoscopic resection beneath the elastic band using the conventional endoscopic electrosurgical snare and electrosurgical generator (Endocut Q current, effect 3, cut duration 2, cut interval 5, VIO300D electrosurgical unit, ERBE, Tuebingen, Germany). [8,10] If perforation occurred after the resection, we used endoscopic clips to close the perforation hole. After successful endoscopic resection, the patient was started on a soft diet the day after the procedure.…”

Duodenal carcinoid tumors, a type of neuroendocrine tumors, are relatively rare and are usually found incidentally during endoscopy. Small duodenal carcinoid tumors (≤10-20 mm), embedded in the submucosa, can be resected endoscopically because of the low risk of metastasis. The aim of this study was to assess the safety and efficacy of ligation-assisted endoscopic mucosal resection (EMR) for the treatment of small duodenal carcinoid tumors. The clinical outcomes of the endoscopic procedures were also evaluated.Between November 2008 and November 2017, a total of 15 duodenal carcinoid tumors embedded in the submucosa were resected using EMR. Two types of EMR (conventional EMR and ligation-assisted EMR) were performed according to tumor morphology (narrow-based and broad-based).The mean tumor size was 6.6 ± 3.9 mm and the mean procedure time was 11.0 ± 11.2 minutes. Most of the lesions (80.0%) were located in the duodenal 1st portion. Broad-based tumors were more common than narrow-based tumors (66.7% vs 33.3%). All broad-based tumors were resected successfully using ligation-assisted EMR. Although en-bloc resection and complete resection rates were higher in ligation-assisted EMR than in conventional EMR ([100% vs 87.5%], and [85.7% vs 62.5%], respectively), the difference was not significant (P = .333 and P = .310, respectively). Moreover, there was no evidence of local or distant metastasis during the follow-up (26.1 ± 20.7 months).Ligation-assisted EMR showed a higher complete resection rate than conventional EMR. Ligation-assisted EMR may be an optimal treatment option for duodenal carcinoid tumors with a broad base.

“…EET can be safely performed in small SMTs. In a study with 36 patients and mean tumor size of 0.6 mm, the overall enbloc and complete resection rates were 100% and 80.6% respectively[68]. There was no local recurrence during follow up of 6 to 82 mo.…”

Esophageal cancer is a highly lethal disease and is the sixth leading cause of cancer related mortality in the world. The standard treatment is esophagectomy which is associated with significant morbidity and mortality. This led to development of minimally invasive, organ sparing endoscopic therapies which have comparable outcomes to esophagectomy in early cancer. These include endoscopic mucosal resection and endoscopic submucosal dissection. In early squamous cell cancer, endoscopic submucosal dissection is preferred as it is associated with cause specific 5-year survival rates of 100% for M1 and M2 tumors and 85% for M3 and SM1 tumors and low recurrence rates. In early adenocarcinoma, endoscopic resection of visible abnormalities is followed by ablation of the remaining flat Barrett’s mucosa to prevent recurrences. Radiofrequency ablation is the most widely used ablation modality with others being cryotherapy and argon plasma coagulation. Focal endoscopic mucosal resection followed by radiofrequency ablation leads to eradication of neoplasia in 93.4% of patients and eradication of intestinal metaplasia in 73.1% of patients. Innovative techniques such as submucosal tunneling with endoscopic resection are developed for management of submucosal tumors of the esophagus. This review includes a discussion of various endoscopic techniques and their clinical outcomes in early squamous cell cancer, adenocarcinoma and submucosal tumors. An overview of comparison between esophagectomy and endoscopic therapy are also presented.
