Tanaka I, Shimamura Y, Inoue H, Azuma D, Ushikubo K, Yamamoto K, Okada H, Nishikawa Y, Tanabe M, Onimaru M. Endoscopic resection for gastric submucosal tumors: A single-center experience in Japan. DEN OPEN 2025; 5:e402. [PMID: 39011512 PMCID: PMC11249007 DOI: 10.1002/deo2.402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 05/22/2024] [Accepted: 06/21/2024] [Indexed: 07/17/2024]
Abstract
Objectives Endoscopic resection (ER) for gastric submucosal tumors (SMTs) has gained prominence in recent years, with studies emerging from various countries. However, there is a paucity of reports from Japan. We aimed to elucidate the efficacy and safety of ER for gastric SMT in Japan. Methods In this retrospective observational study, we investigated the outcomes of consecutive patients who underwent ER for gastric SMT from January 2017 to May 2023. The outcome variables assessed included the complete resection rate, procedure time, closure-related outcomes, and the incidence of adverse events. Results A total of 13 patients were included in the analysis. The median procedure time was 163 (55-283) min. Complete full-thickness resection was performed in seven cases, while in four cases, the serosa remained, and in two cases, the outer layer of the muscularis propria remained. In two cases where the SMT was located on the anterior side, conversion to laparoscopic surgery became necessary, resulting in a procedural success rate of 84.6% (11/13). Excluding these two cases, endoscopic closure of the defect was successfully accomplished in the remaining 11 cases. R0 resection was achieved in 12 out of 13 cases (92.3%). Although one patient had peritonitis, which was successfully treated conservatively, no other treatment-related adverse events were encountered. Conclusions Although ER for SMT on the anterior side may be challenging, our experience revealed that ER is a safe and efficacious approach for gastric SMT.

Long-term outcomes of endoscopic therapy versus surgical resection for 2-5 cm gastric gastrointestinal stromal tumors: A population-based comparative study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108262. [PMID: 38531231 DOI: 10.1016/j.ejso.2024.108262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 03/02/2024] [Accepted: 03/08/2024] [Indexed: 03/28/2024]
Abstract
BACKGROUND Endoscopic therapy (ET) of gastrointestinal stromal tumors (GIST) has become a viable treatment. We intended to compare long-term outcomes of ET versus surgical resection for 2-5 cm GIST using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS A multicenter retrospective study was conducted to compare the long-term outcomes of patients treated with ET and surgical resection for GIST. The multivariate Cox proportional hazards models were used to identify predictors for patients survival. To balance the clinicopathologic characteristics, a 1:1 propensity score matching (PSM) was utilized. RESULTS A total of 749 patients with 2-5 cm GIST were enrolled, of whom 113 accepted ET and 636 underwent surgical resection. Before PSM, there was no significant difference in long-term outcomes between ET and surgical resection (5-year overall survival (OS): 93.5% vs. 91.6%, P=0.374; 5-year cancer-specific survival (CSS): 99.1% vs. 96.5%, P=0.546; 10-year OS: 71.1% vs. 78.2%, P=0.374; 10-year CSS: 93.6% vs. 92.7%, P=0.546). After adjusting for the relevant variables using the multivariable Cox proportional hazards models, we observed that the ET and surgical resection groups were similar in OS (HR 0.726, 95%CI 0.457-1.153, P=0.175) and CSS (HR 1.286, 95%CI 0.474-3.488, P=0.621). After PSM, the long-term OS and CSS of patients with 2-5 cm GIST after ET and surgical resection were comparable. CONCLUSIONS We found that the long-term survival of patients with 2-5 cm gastric GIST after ET and surgical resection were comparable. Further high-quality studies are needed to confirm the role of ET in 2-5 cm GIST.

Abstract
Early gastric cancer (EGC) refers to malignant tumor lesions that are limited to the mucosa and submucosa layers, regardless of the presence of lymph node metastasis. Typically, EGC has a low rate of perigastric lymph node metastasis, and long-term survival outcomes are good after radical surgical treatment. The primary objective of surgical treatment for EGC is to achieve functional preservation while ensuring a radical cure. Sentinel node navigation surgery (SNNS) is a surgical technique used in the treatment of EGC. This approach achieves functional preservation by limiting lymph node dissection and performing restrictive gastrectomy guided by intraoperative negative sentinel node (SN) biopsy. Despite the apparent improvement in the detection rate of SN with the emergence of various tracing dyes and laparoscopic fluorescence systems, the oncological safety of SNNS remains a controversial research topic. SNNS, as a true form of stomach preservation surgery that enhances the quality of life, has become a topic of interest in the EGC field. In recent years, scholars from Japan and South Korea have conducted extensive research on the feasibility and safety of SNNS in the treatment of EGC. This article aims to provide reference choices for surgeons treating EGC by reviewing relevant research on SNNS for EGC in recent years.

Non-exposed endoscopic wall-inversion surgery with one-step nucleic acid amplification for early gastrointestinal tumors: Personal experience and literature review. World J Gastroenterol 2023; 29:3883-3898. [PMID: 37426319 PMCID: PMC10324533 DOI: 10.3748/wjg.v29.i24.3883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 05/11/2023] [Accepted: 05/31/2023] [Indexed: 06/28/2023] Open
Abstract
BACKGROUND Laparoscopic and endoscopic cooperative surgery is a safe, organ-sparing surgery that achieves full-thickness resection with adequate margins. Recent studies have demonstrated the safety and efficacy of these procedures. However, these techniques are limited by the exposure of the tumor and mucosa to the peritoneal cavity, which could lead to viable cancer cell seeding and the spillage of gastric juice or enteric liquids into the peritoneal cavity. Non-exposed endoscopic wall-inversion surgery (NEWS) is highly accurate in determining the resection margins to prevent intraperitoneal contamination because the tumor is inverted into the visceral lumen instead of the peritoneal cavity. Accurate intraoperative assessment of the nodal status could allow stratification of the extent of resection. One-step nucleic acid amplification (OSNA) can provide a rapid method of evaluating nodal tissue, whilst near-infrared laparoscopy together with indocyanine green can identify relevant nodal tissue intraoperatively.
AIM To determine the safety and feasibility of NEWS in early gastric and colon cancers and of adding rapid intraoperative lymph node (LN) assessment with OSNA.
METHODS The patient-based experiential portion of our investigations was conducted at the General and Oncological Surgery Unit of the St. Giuseppe Moscati Hospital (Avellino, Italy). Patients with early-stage gastric or colon cancer (diagnosed via endoscopy, endoscopic ultrasound, and computed tomography) were included. All lesions were treated by NEWS procedure with intraoperative OSNA assay between January 2022 and October 2022. LNs were examined intraoperatively with OSNA and postoperatively with conventional histology. We analyzed patient demographics, lesion features, histopathological diagnoses, R0 resection (negative margins) status, adverse events, and follow-up results. Data were collected prospectively and analyzed retrospectively.
RESULTS A total of 10 patients (5 males and 5 females) with an average age of 70.4 ± 4.5 years (range: 62-78 years) were enrolled in this study. Five patients were diagnosed with gastric cancer. The remaining 5 patients were diagnosed with early-stage colon cancer. The mean tumor diameter was 23.8 ± 11.6 mm (range: 15-36 mm). The NEWS procedure was successful in all cases. The mean procedure time was 111.5 ± 10.7 min (range: 80-145 min). The OSNA assay revealed no LN metastases in any patients. Histologically complete resection (R0) was achieved in 9 patients (90.0%). There was no recurrence during the follow-up period.
CONCLUSION NEWS combined with sentinel LN biopsy and OSNA assay is an effective and safe technique for the removal of selected early gastric and colon cancers in which it is not possible to adopt conventional endoscopic resection techniques. This procedure allows clinicians to acquire additional information on the LN status intraoperatively.

Abstract
The usefulness of laparoscopic and endoscopic cooperative surgery (LECS) for gastric submucosal tumors in the cardiac region has been reported in recent years. However, LECS for submucosal tumors at the esophagogastric junction with hiatal sliding esophageal hernia has not been reported, and its validity as a treatment method is unknown. The patient was a 51-year-old man with a growing submucosal tumor in the cardiac region. Surgical resection was indicated because a definitive diagnosis of the tumor was not determined. The lesion was a luminal protrusion tumor, located on the posterior wall of the stomach 20 mm from the esophagogastric junction, and had a maximum diameter of 16.3 mm on endoscopic ultrasound examination. Because of the hiatal hernia, the lesion could not be detected from the gastric side by endoscopy. Local resection was considered to be feasible because the resection line did not extend into the esophageal mucosa and the resection site could be less than half the circumference of the lumen. The submucosal tumor was resected completely and safely by LECS. The tumor was diagnosed as a gastric smooth muscle tumor finally. Nine months after surgery, a follow-up endoscopy showed reflux esophagitis. LECS was a useful technique for submucosal tumors of the cardiac region with hiatal hernia, but fundoplication might be considered for preventing backflow of gastric acid.

Abstract
BACKGROUND The standard treatment for advanced T2 gastric cancer (GC) is laparoscopic or surgical gastrectomy (either partial or total) and D2 lymphadenectomy. A novel combined endoscopic and laparoscopic surgery (NCELS) has recently been proposed as a better option for T2 GC. Here we describe two case studies demonstrating the efficacy and safety of NCELS.
CASE SUMMARY Two T2 GC cases were both resected by endoscopic submucosal dissection and full-thickness resection and laparoscopic lymph nodes dissection. This method has the advantage of being more precise and minimally invasive compared to current methods. The treatment of these 2 patients was safe and effective with no complications. These cases were followed up for nearly 4 years without recurrence or metastasis.
CONCLUSION This novel method provides a minimally invasive treatment option for T2 GC, and its potential indications, effectiveness and safety needs to be further evaluated in controlled studies.

Abstract
Management of upper gastrointestinal (UGI) tract gastrointestinal stromal tumor (GIST) has evolved significantly over the past two decades. For GIST size smaller than 5 cm, laparoscopic resection has become the current standard. To avoid postoperative gastric deformity and preserve gastric function, laparoscopic endoscopic cooperative surgery (LECS) was developed and various modifications have been reported and utilized successfully. Pure endoscopic resection techniques have also been reported at a similar period of time, which further push the boundary of incisionless surgery in managing these lesions. Both tunneling and nontunneling exposed type endoscopic full thickness resection are well described procedures for resection of small UGI GIST. In this review, a summary of these procedures is provided, and the pros and cons of each technique from the perspective of a surgical endoscopist are discussed in detail. LECS and endoscopic resection are complementary to each other. The choice of technique should be tailored to the location, morphology, and size of the target lesions, taking into account the experience of the laparoscopic surgeons and endoscopists.

Abstract
As one of the most common mesenchymal malignancies in the digestive system, gastrointestinal stromal tumors (GISTs) occur throughout the alimentary tract with diversified oncological characteristics. With the advent of the tyrosine kinase inhibitor era, the treatment regimens of patients with GISTs have been revolutionized and GISTs have become the paradigm of multidisciplinary therapy. However, surgery resection remains recognized as the potentially curative management for the radical resection and provided with favorable oncological outcomes. The existing available surgery algorithms in clinical practice primarily incorporate open procedure, and endoscopic and laparoscopic surgery together with combined operation techniques. The performance of various surgery methods often refers to the consideration of risk evaluation of recurrence and metastases; the degree of disease progression; size, location, and growth pattern of tumor; general conditions of selected patients; and indications and safety profile of various techniques. In the present review, we summarize the fundamental principle of surgery of GISTs based on risk assessment as well as tumor size, location, and degree of progress with an emphasis on the indications, strengths, and limitations of current surgery techniques.

Abstract
OBJECTIVE Lymphagioma, which in most cases as benign tumors, occurs in head, neck, axilla, and mediastinum. Lymphangioma is exceedingly rare in the upper gastrointestinal tract including esophagus, stomach, and duodenum. However, the clinical characteristics, natural history, and recurrence rate after endoscopic resection remain unclear. This study aims to evaluate the characteristic findings and assess the efficacy of endoscopic techniques in the management of this disease. METHODS In this systematic retrospective analysis, we evaluated all 24 cases of upper gastrointestinal lymphangioma resected by endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) and diagnosed by histopathology at our hospital from January 2012 to May 2021. We analyzed the results of endoscopy, endoscopic ultrasonography (EUS), CT, histologic examination, and follow-up assessments. RESULTS 9 male and 15 female patients with esophageal lymphangioma were enrolled in this study, with a mean age of 54.17 ± 11.60 years (range 30-71 years). The lesions' size varied from 2.20 to 40.10 mm, with the median size of 7.83 mm. All patients were evaluated preoperatively, whose endoscopic appearance typically appears as dilated lymphatic channels beneath the surface epithelium of the protrude mucosal or sub-mucosal lesion. Endoscopic ultrasonography revealed the presence of a honeycomb-like or grid-like mass with a heterogeneous echo pattern, and a clear boundary between the lesion and the muscularis propria layer may be helpful for the primary diagnosis of this disease. 22 patients underwent EMR and 2 patient were treated with ESD. Histologic examination revealed that the lesions contained many dilated lymphatic vessels, which confirmed the initial diagnosis of lymphangioma in all patients. No major adverse events were found during the operation or a median follow-up of 43 months (range 13-92). CONCLUSIONS Endoscopic ultrasonography has important clinical value for the primary diagnosis of lymphangioma in the upper gastrointestinal tract. This study also suggests that endoscopic resection should be considered as a more minimally invasive, safe, feasible, and effective therapeutic option comparing to laparoscopic surgery.

Background and study aims Laparoscopic and endoscopic cooperative surgery (LECS) for gastric submucosal tumor was developed as a type of minimal local resection and is now widely used in Asian countries. However, the oncological safety of LECS for gastric gastrointestinal stromal tumor (GIST) remains unclear. LECS has potential oncology-related problems that may influence survival outcomes. Furthermore, the feasibility and safety of LECS have not yet been fully established. Patients and methods Patients who were intended to undergo LECS for gastric GIST from 2006 to 2020 were retrospectively selected. The indication for LECS was determined according to the guidelines. The completion of LECS, complications, and survival outcomes of the patients were analyzed. Results Two hundred fifty-nine patients were eligible in this study. According to intraoperative findings, 44 patients underwent local resection without luminal endoscopic procedures. Of the remaining 215 patients, 213 completely underwent LECS, which corresponds to a completion rate of 99.1 %. Six patients (2.8 %) had postoperative complications of Clavien-Dindo classification grade II or higher. Delayed gastric emptying was most commonly found in four patients (1.9 %). Old age ( P = 0.0349), female sex ( P = 0.0095), tumor located in the lesser curvature ( P = 0.0015), and large tumor diameter ( P = 0.0232) were significantly more common in patients with complications. The 3-year overall and disease-specific survival rates were 99 % and 100 %, respectively, in 215 patients who were intended to undergo LECS. Conclusions Despite several oncological concerns, LECS for gastric GIST is oncologically safe besides a feasible and safe procedure in the short-term.

Abstract
BACKGROUND Schwannomas, also known as neurinomas, are benign tumors derived from Schwann cells. Gastrointestinal schwannomas are rare and are most frequently reported in the stomach. They are usually asymptomatic and are difficult to diagnose preoperatively; however, endoscopy and imaging modalities can provide beneficial preliminary diagnostic data. There are various surgical options for management. Here, we present a case of a large gastric schwannoma (GS) managed by combined laparoscopic and endoscopic surgery.
CASE SUMMARY A 28-year-old woman presented with a 2-mo history of epigastric discomfort and a feeling of abdominal fullness. On upper gastrointestinal endoscopy and endoscopic ultrasonography, a hypoechogenic submucosal mass was detected in the gastric antrum: It emerged from the muscularis propria and projected intraluminally. Computed tomography showed a nodular lesion (4 cm × 3.5 cm), which exhibited uniform enhancement, on the gastric antrum wall. Based on these findings, a preliminary diagnosis of gastrointestinal stromal tumor was established, with schwannoma as a differential. Considering the large tumor size, we planned to perform endoscopic resection and to convert to laparoscopic treatment, if necessary. Eventually, the patient underwent combined laparoscopic and gastroscopic surgery. Immunohistochemically, the resected specimen showed positivity for S-100 and negativity for desmin, DOG-1, α-smooth muscle actin, CD34, CD117, and p53. The Ki-67 index was 3%, and a final diagnosis of GS was established.
CONCLUSION Combined laparoscopic and endoscopic surgery is a minimally invasive and effective treatment option for large GSs.

Abstract
Background The conventional near-infrared fluorescence clip (NIRFC): ZEOCLIP FS®, was difficult to observe using the Firefly on da Vinci. We improved the ZEOCLIP FS® and produced the da Vinci compatible NIRFC. In this report, we describe a robot-assisted wedge resection of a submucosal tumour (SMT) of the stomach using the da Vinci compatible NIRFC. Presentation of case Surgery was performed for an enlarging SMT (from 18 to 22 mm with an intragastric growth type). Through endoscopy, four da Vinci-compatible NIRFCs were placed at the tumour edge two days prior to the surgery. The location of the NIRFC was confirmed when observed with the Firefly. The distal NIRFC site was incised with a monopolar shear blade to identify the NIRFCs and tumour base. The open area was sutured in two layers using a 3-0 V-Loc. The operation time was 83 min, and the amount of blood loss was 2 g. There were no complications or clip dropout. Discussion This method could be performed without intraoperative endoscopist. Conclusion In this case, we were able to observe the position of the da Vinci-compatible NIRFC with Firefly on da Vinci. This technique may be an option as a simple procedure to minimize the resection area of the stomach. This is the first reported case of robot-assisted wedge resection of a submucosal stomach tumour. da Vinci compatible near-infrared fluorescence clip (NIRFC) was used for the procedure. Two clips were used to observe the location of the da Vinci-compatible NIRFC. This technique reduces the resection area needed to treat submucosal tumors. This method could be useful in gastrointestinal stromal tumors without ulcer formation.

Abstract
BACKGROUND Laparoscopic endoscopic cooperative colorectal surgery (LECS-CR) is a promising technique to achieve full-thickness resection of colorectal tumors. This approach has shown good rates of complete resection and low local recurrence, especially for large laterally spreading tumors, which are difficult to remove via endoscopy alone. However, it is often difficult to prevent peritoneal leakage of intestinal content, causing infections and risks of cancer spreading. It was hypothesized that a robotic assistance could make the procedure easier and decrease intestinal fluid leakage. This preclinical trial aims to assess the feasibility of robotic and endoscopic cooperative colorectal surgery (RECS-CR). METHODS LECS-CR was performed in five female pigs and RECS-CR was also performed in five female pigs. With the animal under general anesthesia, pseudotumors were created on the colonic mucosa at a distance comprised between 20 and 25 cm from the anal verge. Desired resection margins were marked endoscopically and two stay sutures were placed either robotically or laparoscopically. A mucosa-to-submucosa dissection was performed endoscopically along the markings. Complete full-thickness dissection was performed cooperatively. The specimen was withdrawn endoscopically. The colon was closed using a self-fixating running suture. Abdominal contaminations, operating times, complications, and complete resections were evaluated and compared between LECS-CR and RECS-CR. RESULTS The mean number of colonies of Escherichia coli in the RECS group was significantly lower than in the LECS group (36.7 ± 30.2 vs. 142.2 ± 78.4, respectively, p < 0.05). Operating time was comparable (118 ± 11.2 vs. 98.6 ± 25.7, respectively, p = 0.22). Two stenoses occurred in the LECS group. R0 resection was achieved in all cases. CONCLUSION This study suggests that RECS-CR is feasible and has the potential to reduce intestinal content leakage, potentially preventing postoperative infections.

Abstract
The aim of this study was to analyze patients who underwent endoscopic resection (ER) for gastric subepithelial tumors (SETs) with a high probability of surgical intervention. Between January 2013 and January 2021, 83 patients underwent ER at the operation theater and 27 patients (32.5%) required backup surgery mainly due to incidental perforation or uncontrolled bleeding despite endoscopic repairing. The tumor was predominantly located in the upper-third stomach (81%) with a size ≤ 2 cm (69.9%) and deep to the muscularis propria (MP) layer (92.8%) but there were no significant differences between two groups except tumor exophytic growth as a risk factor in the surgery group (37% vs. 0%, p < 0.0001). Patients in the ER-only group had shorter durations of procedure times (60 min vs. 185 min, p < 0.0001) and lengths of stay (5 days vs. 7 days, p < 0.0001) but with a higher percentage of overall morbidity graded III (0% vs. 7.1%, p = 0.1571). After ER, five patients (6%) had delayed perforation and two (2.4%) required emergent laparoscopic surgery. Neither recurrence nor gastric stenosis was reported during long-term surveillance. Here, we provide a minimally invasive strategy of endoscopic resection with backup laparoscopic surgery for gastric SETs.

Abstract
Laparoscopic endoscopic cooperative surgery (LECS) refers to the endoscopic dissection of the mucosal or submucosal layers with laparoscopic seromuscular resection. We recommend a treatment algorithm for the LECS procedure for gastric benign tumors according to the protruding type. In the exophytic type, endoscopic-assisted wedge resection can be performed. In the endophytic type, endoscopic-assisted wedge resection of the anterior wall is relatively easy to perform, and endoscopic-assisted transgastric resection, laparoscopic-assisted intragastric surgery, or single-incision intragastric resection in the posterior wall and esophagogastric junction (EG Jx) can be attempted. We propose an algorithm for the LECS procedure for early gastric cancer according to the tumor location. The endoscopic submucosal dissection (ESD) procedure can be adapted for all areas of the stomach, and single-incision ESD can be performed in the mid to high body and the EG Jx. In full-thickness gastric resection, laparoscopy-assisted endoscopic full-thickness resection can be adapted for the entire area of the stomach, but it cannot be applied to the pyloric and EG Jx. In conclusion, surgeons need to select the LECS procedure according to tumor type, tumor location, the surgeon's individual experience, and the situation of the institution while also considering the advantages and disadvantages of each procedure.

Abstract
With advancements in the development of flexible endoscopes and endoscopic devices and the increased demand for minimally invasive treatments, the indications of therapeutic endoscopy have been expanded. Methods of endoscopic treatment used for tissue removal, hemostasis, and dilatation are as follows. Endoscopic submucosal dissection (ESD) is considered the gold standard curative method for removal of gastrointestinal node-negative neoplasms, regardless of their size or the presence of ulcer formation. Laparoscopic endoscopic cooperative surgery (LECS), which incorporates ESD, was introduced for removal of lesions in deeper layers. Another technique is endoscopic full-thickness resection, which is challenging without the assistance of laparoscopy. In terms of hemostasis, management of iatrogenic bleeding after endoscopic treatment is an important issue. Shielding methods and suturing techniques have been introduced for large mucosal defects after ESD, and their efficacy has been investigated clinically. Peroral endoscopic myotomy (POEM) is a new alternative surgical approach for minimally invasive treatment of esophageal achalasia. Furthermore, endoscopic fundoplication after POEM was devised to prevent post-POEM gastroesophageal reflux disease. Many endoscopic treatments, including ESD, LECS, and POEM, have been introduced in Japan. With the aging of the population, more attention will be directed toward therapeutic endoscopy for elderly patients, because it is less invasive. Development of endoscopic treatments with expanded indications is expected.

Abstract
Simple Summary Nonexposure simple suturing endoscopic full-thickness resection (NESS-EFTR) is a recently developed method to prevent the exposure of tumor cells, and we performed a small prospective trial of NESS-EFTR for gastric subepithelial tumors (SETs). In this study, we compared the results of NESS-EFTR trial with those of another small prospective trial of laparoscopic and endoscopic cooperative surgery which was performed in different time period. The results of this study show the feasibility of NESS-EFTR for gastric SETs and provide evidence for the clinical application of the NESS-EFTR procedure. Abstract Recently, nonexposure simple suturing endoscopic full-thickness resection (NESS-EFTR) method was developed to avoid tumor exposure to the peritoneal cavity. The aim of this study is to compare the short-term outcomes of the NESS-EFTR method with those of laparoscopic and endoscopic cooperative surgery (LECS) for gastric subepithelial tumors (SETs). A prospective single-center trial of LECS for gastric SETs was performed from March 2012 to October 2013 with a separate prospective trial of NESS-EFTR performed from August 2015 to June 2017, enrolling 15 patients each. Among the 30 enrolled patients, 14 who underwent LECS and 11 who underwent NESS-EFTR were finally included in the analysis. The rate of complete resection and successful closure was 100% in both groups. The operating time was longer for NESS-EFTR group than for LECS (110 vs. 189 min; p < 0.0001). There were no postoperative complications except one case of transient fever in the NESS-EFTR group. One patient in the LECS group had peritoneal seeding of gastrointestinal stromal tumor at 17 months postoperatively, and there was no other recurrence. Although NESS-EFTR had long operating and procedure times, it was feasible for patients with gastric SETs requiring a nonexposure technique.

Abstract
INTRODUCTION With technique improvements, indications for laparoscopic and endoscopic cooperative surgery (LECS) for gastric subepithelial tumor (SET) are gradually expanding for tumors technically difficult to resect. However, surgical outcomes of LECS, including for esophagogastric junction (EGJ) tumors requiring advanced skills, remain unknown. METHODS We reviewed patients in whom LECS had initially been attempted for gastric SET at the Cancer Institute Hospital in Tokyo from June 2006 to May 2018. Indications for LECS at the EGJ have gradually expanded during the study period to include tumors with esophageal invasion up to 2 cm, or less than half the EJG circumference, preoperatively. Surgical outcomes and risk factors for conversion to other procedures were investigated. RESULTS Twenty (9.3%) of the 214 total patients had EGJ tumors. Four patients (20%) with EGJ tumors developed postoperative complications (Clavien-Dindo grade ≥ II). Among 12 patients in whom LECS could be completed for EGJ tumors, only one non-serious complication occurred. Eight patients required conversion to another operation for EGJ tumors (two laparotomy, six proximal gastrectomy). Among conversion cases with EGJ tumors, anastomotic leakage occurred in both patients undergoing laparotomy after LECS, necessitating additional defect closure. There was only one non-serious complication in six proximal gastrectomy patients. On multivariate analysis, EGJ tumor was an independent risk factor for conversion to another operation. CONCLUSION LECS at the EGJ may be a risk factor for conversion operation, and when performing LECS at the EGJ is difficult, conversion to proximal gastrectomy, which can be performed safely, should be considered.

Abstract
In recent years, a wide range of gastrointestinal endoscopy techniques have been developed, such as endoscopic submucosal dissection (ESD) and endoscopic retrograde cholangiopancreatography (ERCP). Although ESD and ERCP have an important role in gastrointestinal and biliary diseases, each technique has its limitations. Hybrid techniques that combine endoscopic and surgical procedures have emerged that have the advantages of different procedures and negate their limitations at the same time. Laparoscopic endoscopic cooperative surgery and modified laparoscopic endoscopic cooperative surgery combine ESD and laparoscopic techniques to resect submucosal tumors with minimum resection area. Air leak test by intraoperative endoscopy can effectively identify a mechanically insufficient anastomosis and decrease the complication rate. The rendezvous technique that combines percutaneous transhepatic biliary drainage and endoscopy can be performed as a rescue approach for the treatment of biliary obstruction, stenosis and bile duct injuries. For patients with simultaneous presence of stones in the gallbladder and the common bile duct, the laparo-endoscopic rendezvous technique can perform ERCP and laparoscopic cholecystectomy at the same time and reduces the risk of pancreatic injury caused by ERCP. Biliobiliary and bilioenteric anastomosis using magnetic compression anastomosis is another choice for biliary obstruction. The most common used approach to deliver the magnets is by percutaneous-peroral tract. Laparoscopic-assisted ERCP is a safe and highly effective therapy for patients who develop biliary diseases after Roux-en-Y gastric bypass surgery.

Abstract
Recently, there have been important developments in minimally invasive full-thickness resection of subepithelial tumors (SETs) of the upper gastrointestinal tract. However, there remain challenges with techniques such as laparoscopy-endoscopy cooperative surgery (LECS) and non-exposed endoscopic wall-inversion surgery (NEWS). The aim of the present study was to further investigate the feasibility, efficacy and safety of laparoscopy-assisted endoscopic full-thickness resection (ETFR) of SETs and to evaluate the clinical outcomes. This retrospective study included 16 patients with upper gastrointestinal SETs who underwent laparoscopy-assisted EFTR between July 2016 and December 2017. The patient characteristics, surgical outcomes, postoperative course, results of the histopathological examination and short-term outcomes were reviewed and analyzed. A total of 10 patients in the LECS group and 6 patients in the NEWS group presented with SETs in the stomach (15 cases) or duodenum (1 case). The mean tumor size in the LECS group (5.6 cm) was larger compared with that in the NEWS group (2.1 cm). R0 resection was achieved in all patients, without adverse events or tumor recurrence. The NEWS group exhibited a lower white blood cell count and C-reactive protein level on the first postoperative day, reflecting the less prominent inflammatory response, less bleeding and shorter hospitalization. Therefore, laparoscopy-assisted EFTR by LECS and NEWS is a feasible and safe minimally invasive treatment option for upper gastrointestinal SETs in selected patients.

Clinical feasibility and safety of third space robotic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumors dissection : A new surgical technique for treating gastric GISTs. Surg Endosc 2019; 33:4192-4200. [PMID: 31624942 PMCID: PMC6831769 DOI: 10.1007/s00464-019-07223-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 10/09/2019] [Indexed: 02/06/2023]
Abstract
Background Surgical management of gastric gastrointestinal stromal tumors (GISTs) has evolved towards minimal invasiveness. Laparoscopic wedge resection and laparoscopic and endoscopic cooperative surgery had been considered as standard surgical treatments for gastric GISTs > 2 cm. However, stomach deformation and the full-thickness gastric defect caused by these procedures may increase the risk of morbidity. To address these problems, we developed a novel technique, third space robotic and endoscopic cooperative surgery (TS-RECS), which could dissect the tumor entirely while preserving the intact mucosal layer. Here we performed a prospective evaluation of the feasibility and safety of TS-RECS. Methods Patients with gastric GISTs were recruited between April 2018 and April 2019. During the operation, the gastric GIST was located by endoscopic view firstly and the submucosal injection was performed. The tumor was then dissected through robotic surgery. Clinicopathological characteristics, operative data, adverse events, and follow-ups were prospectively collected and analyzed. Results A total of 20 patients with gastric GISTs received TS-RECS. The mean tumor size was 33.0 ± 7.3 mm. R0 resection was achieved in all patients with a median operation time of 115 min and a median blood loss of 20 ml. The integrity of mucosal layer was maintained in 95% (19/20) of the patients. All patients started oral diet on postoperative day 1 or 2, staying in the hospital for a median of 6 days after surgery. There were no major adverse events. Local or distant recurrences were not observed during a median follow-up period of 10 months. Conclusions Our study suggests that TS-RECS appears to be a feasible and safe technique which could be an alternative method for resecting gastric GISTs > 2 cm. Clinical Trials ClinicalTrials.gov NCT03804762.

Abstract
Laparoscopic and endoscopic cooperative surgery (LECS) for gastric submucosal tumors (SMTs) has been developed under the concept of resecting gastric tumors with both complete curability and preserving organ functions. Precise resection is obtained by classical LECS, however, concerns regarding intraoperative bacterial infection and dissemination of the tumor cells into the abdominal cavity by LECS with exposure technique still remain. To prevent these concerns, several LECS-related procedures with non-exposure techniques, such as combination of laparoscopic and endoscopic approaches for neoplasia with non-exposure technique (CLEAN-NET) and non-exposed endoscopic wall-inversion surgery (NEWS), have been reported to be safe and feasible. Classical LECS, CLEAN-NET, and NEWS have the same concept, however, each has its own different characteristic procedures; exposure or non-exposure technique, inversion of the tumor into or outer the lumen, retrieval of tumor per oral or through the abdominal cavity, and dominance in the role of the endoscopist or the laparoscopic surgeon. Familiarization with these procedure details is important to understand their indications, advantages and limitations, resulting in providing a tailored minimally invasive surgery for patients. The main scope of this review article is to introduce readers to the clinical application, procedure, and results of CLEAN-NET, both from previous literatures and from our experience, as well as to offer a closer look at its advantages and limitations while comparing with other LECS procedures from the viewpoint of introducing CLEAN-NET first.

Abstract
Gastric schwannoma is a relatively rare tumor arising from Auerbach plexus in the muscle layer of the gastric wall, and constitutes 0.1% to 0.2% of all gastric tumors and 5% of benign non-epithelium-related gastric tumors. We report the case of a 49-year-old woman in whom upper gastrointestinal endoscopy revealed an approximately 2-cm submucosal tumor on the anterior wall of the fornix of the stomach. Contrast-enhanced computed tomography revealed a homogeneously enhanced lesion (~ 17 mm) in the upper third of the stomach as well as a lesion (~ 25 mm) on the left kidney that was strongly enhanced in the early phase. An 18F-fluorodeoxyglucose positron emission tomography scan revealed high accumulation that is characteristic of gastric tumors. The possibility of malignancy was not completely excluded, and the gastric tumor was resected by non-exposed endoscopic wall-inversion surgery. The patient was discharged with a good prognosis 5 days after surgery. In conclusion, non-exposed endoscopic wall-inversion surgery is a minimally invasive and effective method for resecting small gastric submucosal tumors (diameters < 3 cm) for which preoperative diagnosis is difficult.

Abstract
Laparoscopic and endoscopic cooperative surgery (LECS) is a procedure combining laparoscopic gastric resection with endoscopic submucosal dissection for local resection of gastric tumors with appropriate, minimal surgical resection margins. The LECS concept was initially developed from the classical LECS procedure for gastric submucosal tumor resection. Many researchers reported that classical LECS was a safe and feasible technique for resection of gastric submucosal tumors, regardless of tumor location, including the esophagogastric junction. Recently, LECS was approved for insurance coverage by Japan's National Health Insurance plan and widely applied for gastric submucosal tumor resection. However, the limitations of classical LECS are the risk of abdominal infection, scattering of tumor cells in the abdominal cavity, and tumor cell seeding in the peritoneum. The development of modified LECS procedures, such as inverted-LECS, non-exposed endoscopic wall-inversion surgery, a combination of laparoscopic and endoscopic approaches to neoplasia with a non-exposure technique, and closed-LECS, has almost resolved these drawbacks. This has led to a recent increase in the indication of modified LECS to include patients with gastric epithelial neoplasms. The LECS concept is also beginning to be applied to tumor excision in other organs, such as the duodenum, colon and rectum. Further evolution of LECS procedures is expected in the future. Sentinel lymph node mapping could also be combined with LECS, resulting in a portion of early gastric cancers being treated by LECS with sentinel node mapping.

Abstract
Laparoscopic and endoscopic cooperative surgery (LECS) is a surgical technique that combines laparoscopic partial gastrectomy and endoscopic submucosal dissection. LECS requires close collaboration between skilled laparoscopic surgeons and experienced endoscopists. For successful LECS, experience alone is not sufficient. Instead, familiarity with the characteristics of both laparoscopic surgery and endoscopic intervention is necessary to overcome various technical problems. LECS was developed mainly as a treatment for gastric submucosal tumors without epithelial lesions, including gastrointestinal stromal tumors (GISTs). Local gastric wall dissection without lymphadenectomy is adequate for the treatment of gastric GISTs. Compared with conventional simple wedge resection with a linear stapler, LECS can provide both optimal surgical margins and oncological benefit that result in functional preservation of the residual stomach. As technical characteristics, however, classic LECS involves intentional opening of the gastric wall, resulting in a risk of tumor dissemination with contamination by gastric juice. Therefore, several modified LECS techniques have been developed to avoid even subtle tumor exposure. Furthermore, LECS for early gastric cancer has been attempted according to the concept of sentinel lymph node dissection. LECS is a prospective treatment for GISTs and might become a future therapeutic option even for early gastric cancer. Interventional endoscopists and laparoscopic surgeons collaboratively explore curative resection. Simultaneous intraluminal approach with endoscopy allows surgeons to optimizes the resection area. LECS, not simple wedge resection, achieves minimally invasive treatment and allows for oncologically precise resection. We herein present detailed tips and pitfalls of LECS and discuss various technical considerations.

Abstract
BACKGROUND AND AIMS During endoscopic full-thickness resection (EFTR) for cancers, whether exposure of the lumen to the abdominal cavity during the procedure is acceptable is controversial because of the potential risk of tumor cell seeding. To assess the possibility of transplantation as a result of contact with tumor cells during the procedure, we prospectively investigated the ability of cancer cells to be detached by touching the tumor surface. METHODS In 48 patients with a single early gastric cancer resected by endoscopic submucosal dissection, stamp cytology was performed by touching the surface of the specimens to glass slides. Samples were obtained from cancerous and noncancerous areas, constituting the study and control groups, respectively. The detection rate of malignant class IV or V (C-IV/C-V) samples was investigated with Papanicolaou staining. The rate of CD44v9-positive cases, a cancer stem cell marker, was assessed in C-IV/C-V samples with immunohistochemical staining. RESULTS Detection rates of C-IV/C-V samples in the cancerous group (53/192 slides, 27.6%) differed significantly from those of the C-IV/C-V samples in the noncancerous group (0/96 slides, 0%). Among the 53 slides of C-IV/C-V samples in the cancerous group, CD44v9 cells were expressed in 18 slides (34.0%). CONCLUSIONS These data suggest that cancer cells, including cancer stem cells, in early gastric cancers are easily detached via contact with the tumor surface. In EFTR, a nonexposure approach is recommended to avoid the risk of iatrogenic cancer cell seeding via contact with and transplantation of cancer cells.

Abstract
Endoscopic full-thickness resection combined with laparoscopic surgery was recently developed. These procedures could be categorized as "Cut first and then suture" and "Suture first and then cut". "Cut first and then suture" includes laparoscopic and endoscopic cooperative surgery (LECS) and laparoscopy-assisted endoscopic full-thickness resection (LAEFR). Recent studies have demonstrated the safety and efficacy of LECS and LAEFR. However, these techniques are limited by the related exposure of the tumor and gastric mucosa to the peritoneal cavity and manipulation of these organs, which could lead to viable cancer cell seeding and the spillage of gastric juice into the peritoneal cavity. In the "Suture first and then cut" technique, the serosal side of the stomach is sutured to invert the stomach and subsequently endoscopic resection is performed. In this article, details of these techniques, including their advantages and limitations, are described.

Abstract
BACKGROUND Current endoscopic full-thickness resection (EFTR) methods produce transmural communication and expose the tumor to the peritoneum. An EFTR method with a simple suturing technique that does not expose the gastric mucosa to the peritoneum (non-exposure simple suturing, NESS) was recently developed. To date, there have been no prospective studies that compare EFTR with laparoscopic wedge resection in human or animal. The aim of this study was to compare outcomes between NESS-EFTR and laparoscopic wedge resection (LWR) using the linear staplers in a randomized animal study. METHODS NESS-EFTR includes steps of laparoscopic seromuscular suturing, EFTR of the inverted stomach wall, and endoscopic mucosal suturing with endoloops and clips. Sixteen pigs underwent NESS-EFTR (n = 8) or LWR (n = 8). The resected locations were the cardia, fundus, upper body anterior and greater curvature, antrum lesser and greater curvature side. The pigs were killed 3 weeks after surgery. Rates of successful complete resection (en-bloc resection with clear margins), successful closure, and complications were evaluated. RESULTS The complete resection rates in the NESS-EFTR and LWR groups were 100 and 75%, respectively (P = 0.467). All wounds were successfully closed in both groups. Resected tissues were significantly larger in the LWR group (mean ± SD: 8.0 ± 0.8 cm vs. 4.4 ± 0.5 cm, P < 0.001). Procedure time was significantly shorter in the LWR group (31.7 ± 10.0 min vs. 118.1 ± 23.4 min, P < 0.001). Early deaths due to complications only occurred in the LWR group (a leakage at cardia and a stenosis at the antrum lesser curvature side). CONCLUSIONS Incomplete resection and complications were occurred in only LWR group. NESS-EFTR was feasible and safe in animal.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) techniques, such as generating an artificial space between digestive tract layers for safer dissection, were thought to be safer for the resection of organs in cholecystectomy. We investigated whether combinations of endoscopic techniques and laparoscopic techniques could be performed more safely and rapidly. MATERIAL AND METHODS Laparoscopic and endoscopic cooperative-cholecystectomy (LEC-chole) and conventional laparoscopic cholecystectomy (Lapa-chole) were performed in six dogs. Operation time was defined as the time from the creation of the first port to the retrieval of the resected gallbladder (GB); and GB bed dissection time was the time from local injection of natural saline to the clipping of the cystic duct. The main roles of the endoscope in LEC-chole were to obtain a sufficient cutting space via local injection of natural saline to the GB bed and to monitor the operative view without laparoscopic camera, thus omitting the umbilical port. RESULTS The operation times were 60 ± 18.3 minutes for LEC-chole and 95 ± 7.0 for Lapa-chole (p = .036). The GB bed dissection times were 31 ± 8.54 minutes in LEC-chole and 50.6 ± 7.37 minutes in Lapa-chole (p = 0.048). There were significant differences in liver damage and bleeding (p = 0.116), but there were no significant differences in one-month survival. CONCLUSIONS The application of LEC-chole may be expanded to cholecystectomy.

Abstract
We developed the laparoscopic and endoscopic cooperative surgery (LECS) technique, which combines endoscopic submucosal dissection (ESD) and laparoscopic gastric resection to resect gastric submucosal tumors (SMTs). Many researchers have reported LECS to be a feasible technique for gastric submucosal tumor resection regardless of tumor location, including the esophagogastric junction (EGJ). Recently, the Japanese National Health Insurance system approved LECS for insurance coverage, and it is now widely applied for gastric submucosal tumor resection. Initially, we applied LECS to gastric SMTs without ulcerative lesions due to concern about the possibility of tumor cells seeding into the peritoneal cavity, in a procedure termed "classical LECS". To expand the indication of LECS for gastric epithelial neoplasms, modified LECS procedures such as inverted LECS, non-exposed endoscopic wall-inversion surgery (NEWS), combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique (CLEAN-NET), and closed laparoscopic and endoscopic cooperative surgery (closed-LECS) have been developed and applied to patients with gastric epithelial neoplasms. As a future perspective of LECS, we plan to combine the modified LECS procedure and sentinel node (SN) navigation surgery (SNNS) for clinical (c)Stage IA gastric cancer resection. This strategy could be a minimally invasive surgical technique for cStage IA early gastric cancer.

Abstract
With technological progress of endoscopic submucosal dissection (ESD) in the last decade, several laparoscopic and endoscopic cooperative surgeries (LECS) for gastrointestinal tumor have recently been developed. LECS is definitely favorable to the minimization of surgical margin, which leads to functional and anatomical preservation of gastrointestinal tract. LECS for gastrointestinal tumor is mainly sorted by two categories: exposure procedures and non-exposure procedures between endoluminal and extraluminal spaces. Exposure procedures have the potential risk of gastric contents or tumor cells spilling out over the abdominal cavity, because the stomach wall has to be perforated intentionally during the procedure. In order to avoid the potential these risks, non-exposure procedures have been developed. Currently, the LECS concept has rapidly permeated for treatment of gastrointestinal tumor due to its certainty and safety, although there is still room for improvement to lessen its technical difficulty. This review describes the current LECS for gastrointestinal tumor based on the several articles.

Abstract
BACKGROUND Although endoscopic submucosal dissection (ESD) represents a significant progress in therapeutic endoscopy, little is known about how trainees attain its technical proficiency. The aims of this study were to evaluate the learning curve and clinical outcomes of gastric ESD performed by trainee endoscopists. METHODS Between April 2009 and March 2014, 334 gastric ESD procedures were performed by seven trainees (42-50 consecutive cases per trainee). The learning curve for gastric ESD was evaluated using the cumulative sum (CUSUM) method. Long-term outcomes were also analyzed. RESULTS The calculated CUSUM learning curve comprised three phases: Phase I (the initial 15 cases), Phase II (the middle 15 cases), and Phase III (the final 20 cases). The resection speed was 5.7 ± 3.2 min/cm2 in Phase I, 4.7 ± 2.7 min/cm2 in Phase II, and 4.3 ± 2.2 min/cm2 in Phase III. The resection speed was significantly faster in Phase II than in Phase I (p = 0.019). The rate of self-completion reached more than 95% in Phases II and III. The overall complete resection rate was 95%, showing no significant differences between the three phases. Local recurrence was diagnosed in none of the patients during a median follow-up of 38 months. CONCLUSIONS For the trainees, 30 cases were required to attain a higher technical level of competence in gastric ESD. After the learning curve phase, trainee operators could be expected to complete the procedure successfully with favorable long-term outcomes.
