Endoscopic submucosal dissection (ESD) is a groundbreaking treatment for tumors adjacent to the appendiceal orifice that are difficult to remove by conventional endoscopic mucosal resection, and successful cases are increasingly reported. However, little is known about the subsequent complications, especially long-term complications. A female in her early 70s with a 15-mm cecal tumor adjacent to the appendiceal orifice – discovered incidentally during a screening colonoscopy – underwent hybrid ESD of the lesion. We completely resected the tumor, and she was discharged 5 days later with a pathological diagnosis of high-grade tubular adenoma. Ten months postoperatively, she experienced sudden-onset right lower quadrant pain and was diagnosed with acute appendicitis at another hospital. Due to suspicion that her condition was the result of residual tumor, her surgeon performed an emergency laparoscopic cecectomy. The pathological examination of the resected specimen showed thick scarring adjacent to the appendiceal orifice and no residual tumor. The previous ESD was identified as the cause of the scar, and the scar was the only finding to account for the patient’s appendicitis. This case is significant because the patient required additional surgery due to a complication of ESD. Further, it indicates that acute appendicitis may be a late complication of submucosal dissection near the appendiceal orifice. As ESD becomes more widely used, it is likely that more cecal tumors will be treated endoscopically. It is important to be aware of the late complications of ESD for these tumors.

Abstract Background and study aims Endoscopic submucosal dissection (ESD) is an established method for en bloc resection of large non-pedunculated colorectal lesions in Asia but dissemination of ESD in Western countries is limited. The aim of this study was to evaluate the role of ESD in the management of malignant non-pedunculated colorectal lesions in a European center. Patients and methods Among 255 patients undergoing colorectal ESD between 2014 and 2016, 29 cases were identified as submucosal invasive cancers and included in this study. The main outcomes were en bloc, R0 and curative resection as well as procedural time, complications and recurrence. Results Median tumor size was 40 mm (range 20 – 70 mm). Thirteen cancers were located in the colon and 16 were located in the rectum. Procedural time was 89 minutes (range 18 – 594 minutes). Complete resection was achieved in 28 cases, en bloc and R0 resection rates were 83 % and 69 %, respectively. Curative resection rate was 38 %. One case had a perforation in the sigmoid colon requiring emergency surgery. No significant bleeding occurred. Six patients underwent additional surgery after ESD, one of whom had residual tumor. One recurrence was detected in 20 patients that were followed-up endoscopically, median follow-up time was 13 months (range 2 – 30 months). Conclusion ESD seems to be a safe and effective method for treating non-pedunculated malignant colorectal lesions after careful patient selection and proper endoscopic training.

An 82-year-old male was referred to our institution for evaluation and treatment of a protruding lesion in the stomach. Esophagogastroduodenoscopy (EGD) showed a small protruding lesion and a large superficial elevated lesion on the lesser curvature of the stomach (macroscopic type: 0-I and 0-IIa, resp.). CT and endoscopic ultrasonography (EUS) visualized a small round lymph node (LN) 11 mm in size near the lesser curvature, although submucosal invasion was not evident. These two lesions were resected en bloc by endoscopic submucosal dissection (ESD). Pathological examination of the resected specimen showed moderately differentiated tubular adenocarcinoma (tub2) and well-differentiated tubular adenocarcinoma (tub1), respectively, which were limited to the mucosal layer. Because lymphatic-vascular involvement was not detected by hematoxylin and eosin (HE) staining, additional gastrectomy was not performed. Two months after ESD, follow-up EUS and CT showed an enlarged LN. EUS-guided fine needle aspiration (EUS-FNA) for the LN revealed metastasis. Therefore, total gastrectomy with LN dissection was performed. His postoperative course was uneventful. After discharge, he has been followed up at the outpatient department without any sign of recurrence for 5 years. Histological reexamination of the ESD specimen using immunohistochemistry showed lymphatic invasion of cancer cells in the lamina propria of the 0-I lesion 13 mm in size.

Abstract Background We sometimes experience cases of cervical esophageal cancer which requires laryngectomy due to spread of cancer to larynx. We report a case of esophageal cancer resection with preservation of larynx using intraoperative endoscopic submucosal dissection. Methods The patient was a 59-year-old woman who had dysphagia. She had received total gastrectomy with Roux-en-Y reconstruction for gastric cancer in 2001, chemoradiation (61.2Gy) for esophageal cancer in 2008. Argon plasma coagulation (APC) was performed for the carcinoma in situ of cervical esophagus in 2016. This time superficial 0-IIc tumor was observed at the same site of the scar of APC, and a biopsy revealed squamous cell carcinoma. An endoscopic findings revealed two 0-IIc lesions at distance of 18–22 cm, and 32–34 cm from the incisors, and biopsy resulted in a diagnosis of squamous cell carcinoma. Since tumor was close to the esophageal orifice, the tumor invasion to the larynx was suspected. On the other hand, there were no obvious findings of the submucosal layer invasion, and the both tumor were thought to be limited to the epithelium or lamina propria mucosae (EP/LPM). We performed mediastinoscopic and thoracoscopic transhiatal esophagectomy, subcutaneous ileocolic reconstruction. Results After confirming the tumor invasion to the esophageal orifice by chromoendoscopy with 1% Lugol's iodine solution, we dissected the whole circumference of esophagus in submucosal layer just above the tumor by ESD, put an incision outside of esophageal wall, and resected the esophagus. We preserved short length of muscle layer and performed reconstruction with hypopharynx-ileum anastomosis. Pathological examination revealed squamous cell carcinoma, pT1a-EP, ly0, v0, pPM0, pDM0, pIM0, and curative resection was performed. The postoperative course was uneventful. Conclusion There were no reports of successful larynx-preserving surgery for cervical esophageal cancer using intraoperative ESD. When the tumor was limited in the mucosa, esophagectomy with intraoperative ESD may enable larynx preservation even if the tumor invaded to the esophageal orifice.

Background During endoscopic submucosal dissection (ESD), procedural difficulty and poor visibility of the cutting plane sometimes cause the operator to cut into the lesion from the cutting-plane side, making the vertical margin positive (VM1) or unclear (VMX). In the present study, we evaluated the risk of recurrence of gastric cancer with VM1 /VMX after ESD. Methods In total, 1723 consecutive gastric cancers treated by ESD at Osaka International Cancer Institute from July 2012 to December 2017 were included in this retrospective cohort study. Among them, 231 submucosal or more deeply invasive gastric cancers were excluded because nontechnical factors may contribute to VM1 /VMX in such lesions. To quantify the risk of cutting into cancer from the cutting-plane side during ESD, the proportion of lesions with VM1 /VMX among the pT1a gastric cancers treated by ESD was calculated. The proportion of recurrence among these cases was calculated after exclusion of lesions with positive lymphovascular invasion or a positive horizontal margin in order to eliminate the obvious risk factors for recurrence. Results Among 1492 pT1a gastric cancers treated by ESD, 28 lesions (1.9 %; 95 % confidence interval [CI] 1.3 % – 2.7 %) histologically showed VM1 /VMX. No local recurrence (0.0 %; 95 %CI 0.0 % – 12.2 %) occurred among 23 cases. The median follow-up period was 41 months (range 10 – 84 months). Conclusions No local recurrence was detected in pT1a gastric cancers after VM1 /VMX resection by ESD. Surveillance endoscopy could be adopted for such cases without additional surgery.

Background: Additional surgery after non-curative endoscopic submucosal dissection (ESD) may be excessive as few patients have lymph node metastasis (LNM). It is necessary to develop a risk stratification system for LNM after non-curative ESD, such as the eCura system, which was introduced in the Japanese gastric cancer treatment guidelines. However, the eCura system requires venous and lymphatic invasion to be separately assessed, which is difficult to distinguish without special immunostaining. In this study, we practically modified the eCura system by classifying lymphatic and venous invasion as lymphovascular invasion (LVI). Method: We retrospectively reviewed 543 gastric cancer patients who underwent radical gastrectomy after non-curative ESD between 2006 and 2019. LNM was evaluated according to LVI as well as size >30 mm, submucosal invasion ≥500 µm, and vertical margin involvement, which were used in the eCura system. Results: LNM was present in 8.1% of patients; 3.6%, 2.3%, 7.4%, 18.3%, and 61.5% of patients with no, one, two, three, and four risk factors had LNM, respectively. The LNM rate in the patients with no risk factors (3.6%) was not significantly different from that in patients with one risk factor (2.3%, p = 0.523). Among patients with two risk factors, the LNM rate without LVI was significantly lower than with LVI (2.4% vs. 10.7%, p = 0.027). Among patients with three risk factors, the LNM rate without LVI was lower than with LVI (0% vs. 20.8%, p = 0.195), although not statistically significantly. Based on LNM rates according to risk factors, patients with LVI and other factors were assigned to the high-risk group (LNM, 17.4%) while other patients as a low-risk group (LNM, 2.4%). Conclusions: Modifying the eCura system by classifying lymphatic and venous invasion as LVI successfully stratified LNM risk after non-curative ESD. Moreover, the high-risk group can be simply identified based on LVI and the presence of other risk factors.

Abstract   For patients diagnosed cT1(MM-SM1)N0 esophageal cancer, we perform endoscopic submucosal dissection (ESD) as a primary treatment. Furthermore, additional treatments were performed for the patients diagnosed pT1b(SM) in resected tumor by ESD. Our aim of this study is to investigate whether additional esophagectomy after non-curative ESD can be considered a valid treatment. Methods Forty-four patients who received esophagectomy with lymph node (LN) dissection in neck, mediastinum and upper abdomen as additional surgery after non-curative ESD between 2006 and 2019 were enrolled. Histological examination revealed that squamous cell carcinoma in 41 and adenocarcinoma in 3 patients. We examined the rate of pathological LN metastasis and outcomes of patients received esophagectomy. Results The cT was LPM in 9(20%), MM-SM1 in 35 (80%) patients. However, the pT was MM in 3(7%), SM1 in 14 (32%) and SM2 in 27 (61%) patients. Lymphatic invasion was positive in 32 (73%) and venous invasion was positive in 16(36%) patients. Seven patients had pathological metastatic LN (1–2 LNs/case) (total 10 metastatic LNs). The metastatic LNs existed in neck, mediastinum and upper abdomen. The recurrences were occurred in 2 patients (No.106recL LN and No. 112ao-A LN). One patient died by esophageal cancer (LN recurrence, 38 months alive). One patient died of gastric tube ulcer perforation (16 months). Conclusion We showed that esophagectomy with extended LN dissection is sufficient as additional treatment for the patients treated non-curative ESD. To expand the indications of ESD for pSM esophageal cancer, new methods are needed, such as the risk diagnosis of LN metastasis using genetic analysis.
