Diagnostic procedures for submucosal tumors in the gastrointestinal tract

This review is part one of three, which will present an update on diagnostic procedures for gastrointestinal （GI） submucosal tumors （SMTs）. Part two identifies the classification and part three the therapeutic methods regarding GI SMTs. Submucosal tumors are typically asymptomatic and therefore encountered incidentally. Advances in diagnostic tools for gastrointestinal submucosal tumors have emerged over the past decade. The aim of this paper is to provide the readers with guidelines for the use of diagnostic procedures, when a submucosal tumor is suspected. Literature searches were performed to find information on diagnostics for gastrointestinal submucosal tumors. Based on the searches, the optimal diagnostic procedures and specific features of the submucosal tumors could be outlined. Standard endoscppy, capsule endoscopy and push-and- pull enteroscopy （PPE） together with barium contrast X-ray do not alone provide sufficient information, when examining submucosal tumors. Endoscopic ultrasound （EUS）, computed tomography （CT）, magnetic resonance imaging （MRI） and fluorodeoxyglucose-labeled positron emission tomography （FDG-PET） are recommended as supplementary tools.

Submucosal tunneling endoscopic resection: An effective and safe therapy for upper gastrointestinal submucosal tumors originating from the muscularis propria layer

AIM To evaluate the effectiveness and safety of submucosal tunneling endoscopic resection(STER) and compare its outcomes in esophageal and cardial submucosal tumors(SMTs) of the muscularis propria(MP) layer.METHODS From May 2012 to November 2017, 173 consecutive patients with upper gastrointestinal(GI) SMTs of the MP layer underwent STER. Overall, 165 patients were included, and 8 were excluded. The baseline characteristics of the patients and SMTs were recorded. The en bloc resection rate, complete resection rate,residual rate, and recurrence rate were calculated to evaluate the effectiveness of STER, and the complication rate was recorded to evaluate its safety. Effectiveness and safety outcomes were compared between esophageal and cardial SMTs.RESULTS One hundred and twelve men and 53 women with a mean age of 46.9 ± 10.8 years were included. The mean tumor size was 22.6 ± 13.6 mm. Eleven SMTs were located in the upper esophagus(6.7%), 49 in the middle esophagus(29.7%), 46 in the lower esophagus(27.9%), and 59 in the cardia(35.7%). Irregular lesions accounted for 48.5% of all lesions. STER achieved an en bloc resection rate of78.7%(128/165) for GI SMTs with an overall complication rate of 21.2%(35/165).All complications resolved without intervention or were treated conservatively without the need for surgery. The en bloc resection rates of esophageal and cardial SMTs were 81.1%(86/106) and 72.1%(42/59), respectively(P = 0.142), and the complication rates were 19.8%(21/106) and 23.7%(14/59), respectively,(P =0.555). The most common complications for esophageal SMTs were gas-related complications and fever, while mucosal injury was the most common for cardial SMTs.CONCLUSION STER is an effective and safe therapy for GI SMTs of the MP layer. Its effectiveness and safety are comparable between SMTs of the esophagus and cardia.

Ligation-assisted endoscopic submucosal resection with circumferential mucosal incision for duodenal carcinoid tumor

Here we present the case of a 64-year-old female with a duodenal carcinoid tumor treated by ligation-assisted endoscopic submucosal resection(ESMR-L) with circumferential mucosal incision(CMI). Band ligation was effective in resecting the duodenal carcinoid tumor after CMI,with an uneventful post-procedural course. Histopathological examination showed clear tumor margins at deeper tissue levels. Thus,in the present case,ESMR-L with CMI was useful for the treatment of duodenal carcinoid tumor.

Endoscopic full-thickness resection for gastric submucosal tumors arising from the muscularis propria layer

AIM: To evaluate the efficacy, safety and feasibility of endoscopic full-thickness resection (EFR) for the treatment of gastric submucosal tumors (SMTs) arising from the muscularis propria.METHODS: A total of 35 gastric SMTs arising from the muscularis propria layer were resected by EFR between January 2010 and September 2013. EFR consists of five major steps: injecting normal saline into the submucosa; pre-cutting the mucosal and submucosal layers around the lesion; making a circumferential incision as deep as the muscularis propria around the lesion using endoscopic submucosal dissection and an incision into the serosal layer around the lesion with a Hook knife; a full-thickness resection of the tumor, including the serosal layer with a Hook or IT knife; and closing the gastric wall with metallic clips.RESULTS: Of the 35 gastric SMTs, 14 were located at the fundus, and 21 at the corpus. EFR removed all of the SMTs successfully, and the complete resection rate was 100%. The mean operation time was 90 min (60-155 min), the mean hospitalization time was 6.0 d (4-10 d), and the mean tumor size was 2.8 cm (2.0-4.5 cm). Pathological examination confirmed the presence of gastric stromal tumors in 25 patients, leiomyomas in 7 and gastric autonomous nerve tumors in 2. No gastric bleeding, peritonitis or abdominal abscess occurred after EFR. Postoperative contrast roentgenography on the third day detected no contrast extravasation into the abdominal cavity. The mean follow-up period was 6 mo, with no lesion residue or recurrence noted.CONCLUSION: EFR is efficacious, safe and minimally invasive for patients with gastric SMTs arising from the muscularis propria layer. This technique is able to resect deep gastric lesions while providing precise pathological information about the lesion. With the development of EFR, the indications of endoscopic resection might be extended.     

内镜超声指导食管黏膜下肿瘤的黏膜切除术

目的探讨内镜超声指导食管黏膜下肿瘤黏膜切除术的有效性和安全性。方法对1992年至2005年间656例疑为上消化道黏膜下肿瘤患者进行内镜超声检查，其中97例食管病变内镜超声显示病变来源于黏膜肌层，有43例经知情同意后行内镜下黏膜切除术。切除病变经过病理检查明确病变的层次和病变性质。结果通过与病理结果对照表明，EUS准确地判断肿瘤所在的层次；通过黏膜切除术切除所有病变，无一例发生并发症。结论内镜超声检查能准确判断黏膜肌层来源的肿瘤，可用于指导黏膜切除术。
