BACKGROUND/AIMS: Colonoscopy is commonly used for colorectal cancer screening; therefore, the detection of colon subepithelial tumors (SETs) has also increased. Several research studies have been undertaken to diagnose and treat stomach and rectal SETs. The purpose of this study was to determine a diagnostic point for colon SETs by comparing histological findings with the endoscopic characteristics of colon SETs discovered by chance. METHODS: A total 194 patients underwent an endoscopic ultrasound (EUS) for suspicious colon SETs during a colonoscopy from May 2014 to December 2021...

BACKGROUND AND AIM: Gastrointestinal stromal tumors (GISTs) are treated as malignant gastric subepithelial lesions (SELs), and resection is recommended. However, small gastric SELs < 20 mm with no malignant features are monitored without histopathological examination, and the frequency of malignancy is unknown. This study aimed to clarify the clinicopathological findings and clinical course of gastric SELs < 20 mm measured by endoscopic ultrasound (EUS). METHODS: This retrospective cohort study included consecutive patients with small gastric SELs < 20 mm diagnosed using EUS at a tertiary referral center between 2009 and 2021...

Duodenal neuroendocrine tumors (NETs) are subepithelial tumors that are difficult to remove endoscopically, particularly when located just beyond the pylorus. This paper reports a case of a successful endoscopic submucosal dissection (ESD) using open gastric peroral endoscopic myotomy (POEM) for a remnant duodenal NET detected after endoscopic mucosal resection (EMR). A 67-year-old male presented with a 5 mm remnant duodenal NET close to the pylorus after EMR for a duodenal polypoid lesion performed four months earlier...

Hepatocellular carcinoma (HCC) is an aggressive tumor that usually occurs in patients with chronic liver disease and cirrhosis. Surgical resection is an optimal treatment for HCC, but the 5-year recurrence rates are significantly high. The majority of recurrent HCCs occur through intrahepatic metastasis with local tumor progression, and less than 20% of recurrences are extrahepatic metastases. HCC with gastric metastasis is extremely rare, and it is easily misdiagnosed as primary gastric cancer with liver metastasis...

Subepithelial rectal lesions, including gastrointestinal stromal tumours (GIST), leiomyomas, neuroendocrine tumours, lipomas, and schwannomas, are rare surgical conditions. 1 Surgical management in this region often entails radical surgical excisions with stoma creation. Radical surgical excisions with stoma creation are often required for surgical management in this region. In this video, we demonstrate a transanal minimally invasive surgery (TAMIS) approach to anterior low rectal GIST. Patient underwent neoadjuvant Imatinib Mesylate after multidisciplinary team discussion, and were evaluated preoperatively with colonoscopy, pelvis MRI, and endoscopic ultrasound-guided tissue biopsy...

BACKGROUND: Perineuriomas of the gastrointestinal tract are benign neoplasms that commonly develop in the distal colon and are identified during screening colonoscopy; however, perineuriomas of the stomach are exceedingly rare and less frequently identified. Differentiating gastric perineuriomas from other more serious gastric neoplasms is critical to avoid unnecessarily aggressive treatments. Thus far, only six patients with gastric perineurioma have been described, and the molecular characterization of this entity is still lacking...

BACKGROUND AND AIM: Various techniques for direct biopsy from gastrointestinal subepithelial tumors (SETs) have been reported, although no standard method has been established. A common feature of these techniques is the removal of overlaying mucosa to enable direct biopsies from the SETs. These methods have been synthesized under the collective term "unroofing technique". We conducted a multicenter retrospective study to assess its efficacy and identify potential complications. METHODS: This study was conducted in 10 hospitals and involved all eligible patients who underwent unroofing techniques to obtain biopsies for gastrointestinal SETs between April 2015 and March 2021...

Most gastric subepithelial tumors (SETs) are asymptomatic and are often incidentally discovered during endoscopic procedures conducted for unrelated reasons. Although surveillance is sufficient for the majority of gastric SETs, certain cases necessitate proactive management. Laparoscopic wedge resection, although a viable treatment option, has its limitations, particularly in cases where SETs (especially those with intraluminal growth) are not visualized on the peritoneal side. Recent advances in endoscopic instruments and technology have paved the way for the feasibility of endoscopic resection of SETs...

BACKGROUND: Gastric subepithelial tumors (SETs) may harbor potential malignancy. Although it is well recognized that large SETs should be resected, the precise treatment strategy remains controversial. Compared to surgical resection, endoscopic resection (ER) has many advantages; however, ER of SETs in the cardia is challenging. AIM: To evaluate the safety and efficacy of endoscopic full-thickness resection (EFTR) for the treatment of gastric cardia SETs. METHODS: We retrospectively reviewed data from all patients with SETs originating from the muscularis propria layer in the gastric cardia that were treated by EFTR or submucosal tunneling ER (STER) at Zhongshan Hospital Fudan University between November 2014 and May 2022...

BACKGROUND: Intragastric wedge resection is an effective method for treating endophytic gastric subepithelial tumors (SETs). However, retracting the stomach wall to the umbilicus is difficult in certain patients. In response, we developed a novel surgical technique for single-port intragastric wedge resection, which we termed the "tunnel method." METHODS: A transumbilical incision is made, and a wound retractor is applied. After diagnostic laparoscopy, a gastrostomy is made on the greater curvature, lower body...

Although most esophagus subepithelial tumors are benign, the possibility of malignancy cannot be completely ruled out and it can gradually increase, leading to symptoms such as dysphagia, so removal is still recommended. The narrow cavity and thin walls of the upper esophagus, as well as movement caused by breathing and heartbeat, makes it difficult to perform operation by endoscopy or surgery. Cold snare pulpectomy may been used to remove subepithelial tumors of the upper third of the esophagus due to a low risk of adverse events and short procedure time...
