Subepithelial tumors: How does endoscopic full-thickness resection & submucosal tunneling with endoscopic resection compare with laparoscopic endoscopic cooperative surgery? Endosc Int Open 2022; 10:E1491-E1496.

Abstract
Background and study aims Endoscopic techniques are rapidly emerging for resection of subepithelial tumors (SETs). Submucosal tunneling for endoscopic resection (STER), endoscopic full-thickness resection (EFTR) and laparoscopic endoscopic cooperative surgery (LECS) are current alternatives to open surgery. In this study, we aimed to compare the three endoscopic techniques. Patients and methods Consecutive patients who underwent resection of a submucosal esophageal or gastric lesion at several tertiary care centers were included in a dedicated registry over 3 years. Demographics, size and location of resected lesion, histology of specimen, length of procedure, adverse events (AEs), duration of hospital stay, and follow-up data were collected. Results Ninety-six patients were included (47.7 % male, mean age 62): STER n = 34, EFTR n = 34, LECS n = 280. The lesions included leiomyoma, gastrointestinal stromal tumors (GISTs) and other. The mean lesion size was 28 mm (STD 16, range 20-72 mm). The majority of lesions in the EFTR and laparoscopic-assisted resection group were GISTs. There was no significant difference in clear resection margins, post-procedure complication rates, recurrence rate and total follow-up duration between the groups. However, the LECS group had a procedure time at least 30 minutes longer than STER or EFTR ( P < 0.01). Total hospital stay for the laparoscopic-assisted resection group was also longer when compared to STER (1.5) and EFTR (1.8) ( P < 0.01). Conclusions STER, EFTR, and laparoscopic-assisted resection are efficacious approaches for resection of SETs with similar R0 resection rates, complication rates, and AE rates. Laparoscopic assisted resection appears more time-consuming and is associated with a longer hospital stay.

Abstract
Surgery is the only curative approach for resectable esophageal cancer. This retrospective study was to investigate the immediate effect and operative complications of conventional and modified thoracolaparoscopic esophagectomy with a cervical or abdominal incision to extract specimen for the treatment of patients with esophageal cancer. Eighty-one patients were enrolled, among which 55 patients underwent conventional McKeown thoracolaparoscopic esophagectomy (conventional MTE) and 26 patients underwent modified MTE with a cerivical incision (modified MTE). The clinical, surgical, and postoperative data were analyzed. No significant (P > .05) difference was detected in the clinical data between two groups. The surgical procedure was successful in all patients (100%). The surgical time was significantly (P = .018) shorter in the conventional MTE group than in the modified MTE group (280 min vs 317 min). However, no significant (P > .05) difference was found in blood loss (200 mL vs 180 mL), intensive care unit (ICU) stay (31.3 ± 11.3 vs 25.2 ± 6.4 hours), first flatus after surgery (2.9 ± 1.9 vs 3.3 ± 1.6 days), postoperative hospital stay (12.9 ± 5.6 vs 12.6 ± 3.3 days), total number of lymph nodes dissected (27.9 ± 4.1 vs 26.7 ± 5.7), types of carcinoma, and pathological classification. No significant (P > .05) differences were detected in postoperative complications between the two groups. Assessment of postoperative pain using the visual analogue scale (VAS) score showed a significant (P < .05) difference in the VAS score at day 2 (4.81 ± 1.70 vs 3.87 ± 1.14) and day 3 (5.10 ± 0.83 vs 4.61 ± 1.12) between the conventional and modified MTE groups. The modified McKeown thoracolaparoscopic esophagectomy with only one cervical incision is more minimally invasive, more cosmetic, and less painful than the conventional approach.

Abstract
BACKGROUND This study aimed to compare the clinical outcomes between submucosal tunneling endoscopic resection (STER) and endoscopic submucosal dissection (ESD) for large subepithelial esophageal lesions (SELs) and analyze risk factors for perforation and piecemeal resection. METHODS The clinicopathological features and outcomes of endoscopic treatment of 56 patients with SELs with diameters ≥30 mm, diagnosed between June 2017 and December 2020, were reviewed in this retrospective cohort study. Patients were divided into two groups (ESD group and STER group). RESULTS The complete resection rates of the STER and ESD groups were 88.1% and 78.6%, respectively (p = .398). The operation time of STER was longer than ESD (p = .03), while the hospital stay of STER was shorter than ESD (p = .02). The rate of major adverse events associated with ESD was considerably higher than STER group (p = .035). The extraluminal growth pattern was a risk factor for piecemeal resection, and ESD was an independent risk factor for perforation. Regarding tumors with extraluminal growth patterns, the ESD group's perforation rate was significantly higher than the STER group (p = .009). There were no recurrence or metastases found during a mean follow-up of 24.4 months. CONCLUSION The STER technique has advantages of shorter hospital stays and fewer major adverse events than ESD. The extraluminal growth pattern seems to be a risk factor for piecemeal resection in both ESD and STER. STER appears to be a preferable choice for large SELs with extraluminal growth patterns.

Abstract
INTRODUCTION When using the endoscopic submucosal tunnel technique (ESTT), the working space in the submucosal tunnel is limited, and the visual field is obscured during close inspection or hemostasis. We aimed to evaluate the efficacy and safety of near-focus mode technique for accurate operation during the submucosal tunneling endoscopic procedure. MATERIAL AND METHODS A retrospective two-center study was designed. A total of 51 patients undergoing ESTT procedures with near-focus mode (n = 29) or traditional mode (n = 22) between February 2016 and May 2019 were included in this study. RESULTS When using the near-focus mode during the ESTT procedure, it is convenient to ensure a clear image and accurate operation. Adverse events occurred more frequently in the traditional group than in the near-focus group (45.5% vs 17.2%, p = .036). The near-focus group exhibited a lower rate of bleeding compared to the traditional group (0 vs 18.2%, p = .029). Furthermore, the mean hospital stay after the procedure was shorter in the near-focus group than in the traditional group (5.7 days vs 6.7 days, p = .013). CONCLUSIONS The visual field is more clearly exposed during submucosal tunneling when using the near-focus mode than when using traditional procedures. This technique appears to be more efficient and secure than the traditional ESTT procedure.

Abstract
Purpose To investigate the lymph node metastasis pattern and significance of dissection of the left gastric artery lymph nodes in radical en bloc esophagectomy for esophageal squamous carcinomas based on the lymphatic drainage pathway revealed by carbon nanoparticle labeling. Materials and methods Patients who underwent en bloc esophagectomy endoscopically were retrospectively enrolled. Carbon nanoparticles were injected in the submucosa of upper thoracic esophagus to label the relevant draining lymph nodes. The clinical data, lymph nodes dissected, surgical technique, and complications were analyzed. Results En bloc esophagectomy was successful in all 179 patients. Metastases to the left gastric artery lymph nodes were positive in 42 patients (23.5%) but negative in 137 (76.5%). The left gastric lymph nodes were labeled, whereas no celiac lymph nodes were labeled by carbon nanoparticles. A total of 4652 lymph nodes were resected, with 26 lymph nodes per patient. Seventy-three patients had lymph node metastasis (73/179). Seventeen patients had metastasis to the recurrent laryngeal nerve lymph nodes (9.5%). The metastasis rate of the lower thoracic esophageal cancer to the left gastric artery lymph nodes was 37.0%, significantly greater than that at the middle (15.4%) or upper (6.7%) thoracic segment. The lymph node metastasis rate was significantly (P < 0.05) increased with the length of the cancerous lesion, infiltration depth, and poor differentiation. Univariate analysis revealed that the metastasis rate to the left gastric artery lymph nodes was significantly (P < 0.05) associated with paraesophageal lymph node metastasis, para-cardial lymph metastasis, and TNM classification. Multivariate analysis indicated that cancer location (odds ratio 8.32, 95% confidence interval 2.12–32.24) was significantly (P < 0.05) associated with metastasis to the left gastric artery lymph nodes, with the cancer at the middle and lower thoracic segments significantly more than in the upper thoracic segment. Conclusion Certain patterns exist in lymph node metastasis of esophageal cancer, and in radical esophagectomy of esophageal cancers, dissection of the left gastric artery lymph nodes is necessary to prevent possible residual or metastasis of esophageal squamous carcinomas based on the lymphatic drainage pathway of esophageal carcinomas demonstrated by carbon nanoparticle labeling.

Abstract
BACKGROUND To evaluate the effectiveness of endoscopic submucosal tunnel dissection (ESTD) and endoscopic submucosal dissection (ESD) in superficial esophageal neoplastic lesions (SENL). METHODS A comprehensive search for studies investigating the efficacy of ESTD and ESD for SENL was conducted to search for relevant studies through PubMed, Web of Science, Cochrane Library, SinoMed, CNKI, and Wanfang. Weighted pooled rates were calculated for en bloc resection rate, R0 resection rate, operation time, dissection area, dissection speed, and adverse events. The 95% confidence intervals (95%CI) for effect size were used to calculate the pooled value using the fixed- or random-effects model. RESULTS A total of seventeen studies with 1161 patients were identified and included in the meta-analysis. The pooled analysis showed that ESTD had significantly higher en bloc resection (OR 3.98; 95% CI 1.74 to 9.12; p = 0.001) and R0 resection rates (OR 2.29; 95% CI 1.54 to 3.46; p < 0.001) than ESD. The operation time in the ESTD group was shorter than that in the ESD group (SMD = - 0.57; 95% CI - 0.95 to - 0.19; p = 0.003). The dissection area of the ESTD group was larger than that in the ESD group (SMD = 0.49; 95% CI 0.16 to 0.83; p = 0.004), and the dissection speed is faster than that in the ESD group (SMD = 1.52; 95%CI 1.09 to 0.83; p < 0.001). There were no significant differences in esophageal stenosis (p = 0.94) between the two techniques. However, ESTD was superior to ESD in other adverse events (p < 0.05). CONCLUSION ESTD has a significant advantage over ESD in the treatment of SENL. ESTD has significantly higher en bloc and R0 resection rates and reduced adverse events.

Abstract
Objective To analyze the types and properties of cystic lesions originating from the muscularis propria of the gastric cardia (CLMPGC), explore the growth pattern and anatomical characteristics, and evaluate the safety, feasibility, and clinical efficacy of endoscopic esophageal submucosal tunnel dissection (ESTD). Methods From September 2013 to July 2018, we treated 6 patients with CLMPGC whom we had diagnosed using endoscopy, endoscopic ultrasound (EUS), and Computed Tomography (CT) before the operations. ESTD was the best option for treatment for all these patients. Postoperative observation and follow-ups were performed, and the operational, clinical data, and treatment results are analyzed. Results The mean age of the patients was 50.67 ± 11.59 years (male : female = 1 : 1). The only clinical manifestations the patients exhibited were upper abdominal discomfort. The diameter of the masses was 2.05 ± 0.73 (1.1-3.0) cm. The duration of the ESTD operation was 93.5 (82-256) mins, and the length of hospital stay was 7.50 ± 1.38 days. Postoperative pathology showed 4 cases of an epithelioid cyst, and 2 cases of mucocele with xanthogranuloma. There were no complications, such as hemorrhage, pneumothorax, and pleural effusion during and after the operation. No recurrence during the follow-ups was observed. Conclusion The CLMPGC were mainly mucocele and epidermoid cyst, in an expansive growth pattern, and these lesions had no distinct borders with the muscularis propria. The muscularis propria formed a complete wall of the lesion. There was no direct blood supply to the lesions from big blood vessels. Endoscopic esophageal submucosal tunnel dissection was a safe, feasible, and effective treatment for CLMPGC.

Abstract
BACKGROUND Presently, endoscopic submucosal tunnel dissection (ESTD) has been a novel therapy for superficial esophageal neoplastic lesions (SENL), especially for circumferential neoplastic lesions. A number of studies have reported the clinical application of ESTD with promising outcomes. Therefore, we conducted a systematic review and meta-analysis to evaluated the efficacy and safety of ESTD for SENL . METHODS From 2013 to November 2018, Pubmed, Embase and Cochrane databases were searched to determine studies reporting ESTD treatment of SENL. Weighted pooled rates (WPR) were calculated for en bloc resection, R0 resection and complication of ESTD. Risk ratios (RR) were calculated and pooled to compare the clinical outcomes of ESTD with ESD for SENL. RESULTS A total of 9 studies involving 494 patients with 518 esophageal neoplastic lesions were included in our study. WPR for en bloc resection and R0 resection of ESTD was 97.0% (95% CI: 94.7-98.3%) and 84.1% (95% CI: 80.5-87.1%), respectively. WPR for complication was 40.0% (95% CI: 25.8-56.1%). Two studies with 265 patients compared the performance of ESTD with ESD. Pooled RR for en bloc resection and R0 resection was 1.04 (95% CI: 0.95-1.14, P = 0.42) and 1.01 (95% CI: 0.93-1.10, P = 0.73), respectively. Pooled RR for complication was 0.68 (95% CI: 0.46-1.01, P = 0.05). CONCLUSION Our study showed that ESTD is effective for treating SENL with high en bloc resection rate and R0 resection rate, but accompanying by a relatively high complications.

Abstract
Background: Endoscopic submucosal excavation (ESE), endoscopic full-thickness resection (EFTR) and submucosal tunneling endoscopic resection (STER) have been widely applied to upper gastrointestinal submucosal tumors (SMTs) originating from the muscularis propria (MP) layer in recent years. But until now, there are few studies that comparing the efficacy and safety of three endoscopic therapy methods.Method: From January 2013 to August 2018, a total of 218 patients with SMTs who underwent ESE, EFTR or STER were enrolled in this retrospective study. Clinicopathological characteristics, endoscopic features, complication and follow-up data were analyzed.Result: There were 114 patients underwent ESE, 61 underwent EFTR and 43 underwent STER, respectively. The en bloc and complete resection rates in STER group (83.7% and 90.0%) were significantly lower and postoperative complication rate (62.8%) was significantly higher than those of the other 2 methods. Furthermore, for lesions <40 mm, no significant differences were found in the en bloc rate, complete rate and postoperative complication rate among 3 methods. The perforation rate decreased in the order of EFTR (100%), ESE (23.7%), STER (7.0%). The median number of clips, fasting time and hospital stay were lowest in ESE group (5, 2 days, and 7 days). And the cost was highest in EFTR group ($4993.1). There were no differences in the bleeding and recurrence rates among three groups.Conclusion: For SMTs <40 mm, the efficacy among 3 ER methods are comparative. The choice of ER methods mainly based on the comprehensive consideration of lesion size, location, growth pattern and clinical experience of endoscopists. For benign SMTs ≥40 mm in stomach, ESE and EFTR becomes alternative choices.

Transl Gastroenterol Hepatol 2019; 4:39. [PMID: 31231706 DOI: 10.21037/tgh.2019.05.01] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2019] [Accepted: 04/26/2019] [Indexed: 02/06/2023] Open
Abstract
Endoscopic full-thickness resection (EFTR) and submucosal tunneling endoscopic resection (STER) are the frontier of therapeutic endoscopic. These two methods rely on the skillset and equipment of endoscopic submucosal dissection (ESD) while going beyond the boundaries of the gastrointestinal lumen. They are both representatives of natural orifice transluminal endoscopic surgery, with STER being a direct off-shoot of peroral endoscopic myotomy (POEM). Both techniques are designed for the removal of gastrointestinal tumors originating from the muscularis propria but tend to be used in different organs and come with respective challenges. In this review we will go over the history, indication, technique and literature of these two techniques.

Abstract
Objectives: Submucosal tunneling endoscopic resection (STER) is a novel therapeutic approach for upper gastrointestinal submucosal tumors (SMTs) especially for tumors originating from the muscularis propria layer. Presently, several studies have reported the efficacy and safety of STER for SMTs. Therefore, we conducted this study to review the clinical outcomes of STER with more than 1-year' follow-up duration. Materials and methods: Medline, Embase and Cochrane databases were searched on November 2018 to identify studies reporting STER for SMTs. Weighted pooled rates were calculated for en bloc resection, complete resection and adverse event (AE). Risk ratios (RR) were calculated and pooled to compare STER with thoracoscopic enucleation (TE). Results: A total of 701 patients with 728 lesions from 12 original studies were review. Pooled WPR for en bloc resection of STER was 86.3% (95% CI: 74.5-93.1%), (I2=82.5). Pooled WPR for complete resection of STER was 97.7% (95% CI: 92.8-99.3%), (I2=77.6). WPR for AE was 18.3% (95% CI: 9.7-31.6%), (I2=90.6%). Two studies with 292 patients compared the performance of STER with TE. Pooled RR for en bloc resection was 1.02 (95% CI: 0.95-1.09). Pooled RR for complete resection was 1.0 (95% CI: 0.98-1.03). Pooled RR for AE was 0.82 (95% CI: 0.33-2.05). Conclusions: Our study showed that STER has relatively long-term efficacy for treating upper gastrointestinal SMTs, and the incidence of AE was not low for STER, but all of them can be managed conservatively.

Abstract
With the digestive endoscopic tunnel technique (DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria (MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal (GI) tract. At present, the tunnel technique application range covers the following: (1) Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis; (2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and (3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment. The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism, and significance of DETT, prevention of infection and concepts of DETT-associated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract (indications and contraindications, procedures, pre- and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations).

Chang KJ. Endoscopic foregut surgery and interventions: The future is now. The state-of-the-art and my personal journey. World J Gastroenterol 2019; 25:1-41. [PMID: 30643356 PMCID: PMC6328959 DOI: 10.3748/wjg.v25.i1.1] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 12/13/2018] [Accepted: 12/14/2018] [Indexed: 02/06/2023] Open
Abstract
In this paper, I reviewed the emerging field of endoscopic surgery and present data supporting the contention that endoscopy can now be used to treat many foregut diseases that have been traditionally treated surgically. Within each topic, the content will progress as follows: "lessons learned", "technical considerations" and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years. Finally, future opportunities will address current unmet needs and potential new areas of development. The foregut is defined as "the upper part of the embryonic alimentary canal from which the pharynx, esophagus, lung, stomach, liver, pancreas, and part of the duodenum develop". Foregut surgery is well established in treating conditions such as gastroesophageal reflux disease (GERD), achalasia, esophageal diverticula, Barrett's esophagus (BE) and esophageal cancer, stomach cancer, gastric-outlet obstruction, and obesity. Over the past decade, remarkable progress in interventional endoscopy has culminated in the conceptualization and practice of endoscopic foregut surgery for various clinical conditions summarized in this paper. Regarding GERD, there are now several technologies available to effectively treat it and potentially eliminate symptoms, and the need for long-term treatment with proton pump inhibitors. For the first time, fundoplication can be performed without the need for open or laparoscopic surgery. Long-term data going out 5-10 years are now emerging showing extended durability. In respect to achalasia, per-oral endoscopic myotomy (POEM) which was developed in Japan, has become an alternative to the traditional Heller's myotomy. Recent meta-analysis show that POEM may have better results than Heller, but the issue of post-POEM GERD still needs to be addressed. There is now a resurgence of endoscopic treatment of Zenker's diverticula with improved technique (Z-POEM) and equipment; thus, patients are choosing flexible endoscopic treatment as opposed to open or rigid endoscopy options. In regard to BE, endoscopic submucosal dissection (ESD) which is well established in Asia, is now becoming more mainstream in the West for the treatment of BE with high grade dysplasia, as well as early esophageal cancer. In combination with all the ablation technologies (radiofrequency ablation, cryotherapy, hybrid argon plasma coagulation), the entire spectrum of Barrett's and related dysplasia and early cancer can be managed predominantly by endoscopy. Importantly, in regard to early gastric cancer and submucosal tumors (SMTs) of the stomach, ESD and full thickness resection (FTR) can excise these lesions en-bloc and endoscopic suturing is now used to close large defects and perforations. For treatment of patients with malignant gastric outlet obstruction (GOO), endoscopic gastro-jejunostomy is now showing better results than enteral stenting. G-POEM is also emerging as a treatment option for patients with gastroparesis. Obesity has become an epidemic in many western countries and is becoming also prevalent in Asia. Endoscopic sleeve gastroplasty (ESG) is now becoming an established treatment option, especially for obese patients with body mass index between 30 and 35. Data show an average weight loss of 16 kg after ESG with long-term data confirming sustainability. Finally, in respect to endo-hepatology, there are many new endoscopic interventions that have been developed for patients with liver disease. Endoscopic ultrasound (EUS)-guided liver biopsy and EUS-guided portal pressure measurement are exciting new frontiers for the endo-hepatologists.

Abstract
BACKGROUND AND AIM Endoscopic submucosal tunnel dissection (ESTD) has been used for dissection of esophageal and gastric lesions. However, outcomes of ESTD for large lesions in the lesser gastric curvature had not been acknowledged because previous reports had the limitations of being single-center studies. We aimed to clarify the outcomes of ESTD for large lesser gastric curvature superficial neoplasms and provide our experience to accelerate its application. METHODS Between July 2014 and July 2016, 87 patients with early cancer in the lesser gastric curvature treated at six Chinese institutions were enrolled. Our primary outcome was dissection speed. Moreover, both efficacy and safety clinical data were collected and analyzed retrospectively. RESULTS All of the 87 patients were found to successfully undergo ESTD or ESD. Of these, 32 underwent ESTD and 55 underwent endoscopic submucosal dissection (ESD). The ESTD group had a higher dissection speed (18.0 mm2/min vs. 7.8 mm2/min, p < 0.01) and was associated with higher en bloc resection rate (100% vs. 87.3%, p = 0.035) and curative resection rate (100% vs. 85.5%, p = 0.024) compared with the ESD group. No perforation or muscular injury occurred in the ESTD group and its intraprocedural bleeding rate was lower (59.4% vs. 100%, p < 0.01) than that of the ESD group. CONCLUSIONS In this multicenter retrospective study, outcomes of ESTD were excellent with a higher dissection speed and radical curative rate compared with ESD.

Abstract
Endoscopic full-thickness resection (EFTR) is a "changing-concept" endoscopic resection technique, which safely allows resecting deep submucosal tumors (SMTs) in the gastrointestinal (GI) wall. It's a highly promising endoscopic procedure that allows full-thickness excision of a small piece of the complete GI wall by using only a flexible endoscope. EFTR is a meeting point between surgery and endoscopy and probably the onset of many prospective combined minimally invasive therapeutic techniques that science will explore. In this review, use of the EFTR technique for gastrointestinal SMTs is highlighted, focusing on some technical aspects, indications, contraindications and outcomes.
