“…Hence, only the study [14] with the longer time interval was included in our review and the other study [24] was excluded to avoid duplication of data. Of the remaining 16 studies, three were case reports [13,16,22], nine were retrospective studies [8,11,12,14,15,17-19,21] and four were prospective studies [9,10,20,23]. All studies except two [16,23] were conducted in China [8-15,17-22], which could have led to bias in our results.…”

“…In the study by Ye et al , the authors reported using noninvasive tests such as CT scan, abdominal US and chest radiograph on an annual basis to rule out distant metastasis among subjects with GIST, in addition to the use of endoscopy and EUS to rule out local recurrence [9]. The follow-up interval varied widely across different studies and even within a given study, from as short as 1 month [10,12] to as long as 36 months [11]. The details from individual studies are summarized in Table 1.…”

The management of incidentally discovered small upper gastrointestinal (GI) tract submucosal tumors (SMT) remains debatable. In this review, we summarize the evolving experience with submucosal tunneling endoscopic resection (STER) of upper GI SMTs originating from the muscularis propria. From 16 original studies, we reviewed a total of 703 patients with 736 lesions. Of these, 436 were located in the esophagus, 146 in the esophagogastric junction (EGJ) and 154 in the stomach. The composite complete resection rate (CRR) for STER of upper GI tumors arising from the muscularis propria layer was 99.8% (445/446). The composite CRR for STER of esophageal, EGJ and gastric SMTs arising from the muscularis propria layer was 100% (208/208),100% (78/78)and 100% (115/115), respectively. The composite en bloc resection rate (EBRR) for STER of upper GI tumors arising from the muscularis propria layer was 94.6% (679/718). The composite EBRR for STER of esophageal, EGJ and gastric SMTs arising from the muscularis propria layer was 98.6% (205/208), 96.2% (75/78) and 97.9% (95/97), respectively. Tumor recurrence rate was 0%. The reported complication rate for STER was high but the majority responded to conservative management. STER is a minimally invasive and efficacious alternative to surgery, especially for patients with small tumors (<3 cm). Careful selection of candidates remains crucial for excluding potentially malignant tumors.

“…All tumors were resected successfully, the mean procedural time was 49.0 minutes, which was comparable to other studies (range, 40 to 78.3 minutes). 12 – 15 Due to the large size (40 mm), three esophageal tumors were piecemeal resected. There may be a concern whether piecemeal resection could result into the recurrence of tumor.…”

Background/AimsIn recent years, endoscopic submucosal tunnel dissection (ESTD) has gained popularity worldwide. The aim of this study was to evaluate the safety and efficacy of ESTD in treating upper gastrointestinal submucosal tumors (SMTs) in a large-volume endoscopic center.MethodsPatients with SMTs were enrolled in this study between January 2012 and January 2015. Demographic data, clinical data, and treatment outcome were collected and analyzed.ResultsSeventy SMTs originating from the muscularis propria (MP) layer were identified in 69 patients. All patients successfully underwent the ESTD procedure. The mean procedure time was 49.0±29.5 minutes, and the mean tumor size was 18.7±7.2 mm. Among all lesions, the majority (70.0%) were located in the esophagus, 12.9% in the cardia, and 17.1% in the stomach. Complete resection was achieved in 67 lesions (95.7%). Perforation occurred in three patients (4.3%), who were treated by endoclips. Pneumothorax occurred in two patients (2.9%) and was successfully managed by thoracic drainage. During a median follow-up of 18.1 months, patients were free of local recurrence or distant metastasis.ConclusionsOur results demonstrated the feasibility and safety of ESTD in treating upper gastrointestinal SMTs originating from the MP layer. Large-scale comparative studies with other treatment methods should be conducted in the future.
