    OBJECTIVES: A Japanese multicenter prospective cohort study examining endoscopic resection (ER) for early gastric cancer (EGC) has been conducted using a Web registry developed to determine the short-term and long-term outcomes based on absolute and expanded indications. We hereby present the short-term outcomes of this study. METHODS: All consecutive patients with EGC or suspected EGC undergoing ER at 41 participating institutions between July 2010 and June 2012 were enrolled and prospectively registered into the Web registry. The baseline characteristics were entered before ER, and the short-term outcomes were collected at 6 months following ER. RESULTS: Nine thousand six hundred and sixteen patients with 10 821 lesions underwent ER (endoscopic submucosal dissection [ESD]: 99.4%). The median procedure time was 76 min, and R0 resections were achieved for 91.6% of the lesions. Postoperative bleeding and intraoperative perforation occurred in 4.4% and 2.3% of the patients, respectively. Significant independent factors correlated with a longer procedure time (120 min or longer) were as follows: tumor size >20 mm, upper-third location, middle-third location, local recurrent lesion, ulcer findings, gastric tube, male gender, and submucosa. Histopathologically, 10 031 lesions were identified as common-type gastric cancers. The median tumor size was 15 mm. Noncurative resections were diagnosed for 18.3% of the lesions. Additional surgery was performed for 48.6% (824 lesions) of the 1695 noncurative ER lesions with a possible risk of lymph node (LN) metastasis. Among them, 64 (7.8%) exhibited LN metastasis. CONCLUSIONS: This multicenter prospective study showed favorable short-term outcomes for gastric ESD.

    Background and study aims  A post-endoscopic submucosal dissection (ESD) scar is expected to look homogeneous, however, some patients develop benign polypoid nodule scar (PNS). Incidence of PNS is unknown, yet these scars have direct clinical implications because they may render evaluation of post-ESD neoplastic recurrence difficult. Therefore, we reviewed the clinical experience of 5 ESD referral centers and evaluated their PNS incidence and clinical management. Patients and methods  This was a retrospective multicenter case series enrolling patients that underwent R0, curative gastric ESD from 2003 to 2015 in 5 academic centers. PNS was defined as ESD site nodularity with hyperplastic or regenerative tissue histology. Results  A total of 2275 patients underwent gastric ESD with endoscopy control and 28 patients (18 men/10 women) developed PNS for overall incidence of 1.2 %. Incidence of PNS ranged from 0.15 % to 11.4 % between centers. All patients that developed PNS had primary neoplastic lesions located in the distal stomach. Considering only lesions situated in the antrum (n = 912), incidence of PNS was 3.1 %. After mean follow-up of 43 months (range 6 - 192), no malignant recurrence in the PNS has been identified. In five patients (17.8 %) PNS disappeared after a mean of 18 months. Conclusion  PNS occurs exclusively after ESD in the distal stomach in approximately 3.1 % of patients. Although PNS appearance can be concerning, no malignant recurrence was observed after curative R0 resection. Therefore, PNS should be viewed as a benign alteration that does not require any type of intervention, other than endoscopic surveillance.

    A 73-year-old female with a 6-month history of progressive dysphagia and chest pain was referred to our hospital. She underwent esophagogastroduodenoscopy, which revealed abnormally strong contractions in the distal esophagus. Esophageal biopsy specimens showed massive eosinophil infiltration into the epithelium, and high-resolution manometry (HRM) also demonstrated abnormally strong contractions in the distal esophagus. Based on these results, she was diagnosed with Jackhammer esophagus (JHE) due to eosinophilic esophagitis (EoE). Treatment was started with 5 mg/day of prednisolone (PSL), and the number of peripheral blood eosinophils quickly decreased without any improvement in the patient's dysphagia. Esophageal biopsy specimens obtained after the PSL treatment showed the disappearance of eosinophils from the epithelium. However, abnormally strong contractions were still detected on HRM. Per-oral endoscopic myotomy (POEM) was performed to treat the JHE. Interestingly, the intraoperative esophageal muscle biopsy sample demonstrated massive eosinophil infiltration into the muscle layer. After the POEM, the patient's symptoms improved, and abnormal contractions were no longer detected on HRM. The current case suggests that when EoE combined with an esophageal motility disorder are refractory to steroid therapy, clinicians should be aware that motility disorders can develop due to eosinophil infiltration deep into the esophageal muscularis propria.

    BACKGROUND: Although endoscopic submucosal dissection has enabled complete tumor resection and accurate pathological assessment in a manner that is less invasive than surgery, the complete resection of lesions with severe fibrosis in the submucosal layer and exhibiting the muscle-retracting sign is often difficult. We have devised a new method, peranal endoscopic myectomy (PAEM), for rectal lesions with severe fibrosis, in which dissection is performed between the inner circular and outer longitudinal muscles, and have examined the usefulness and safety of this new technique. METHODS: All of the patients who underwent PAEM in our hospital and affiliated hospitals between July 2015 and June 2017 were retrospectively reviewed. RESULTS: 10 rectal lesions were treated with PAEM. En bloc resection with a negative vertical margin was achieved in eight patients (80 %), whose lesions were mucosal (n = 2), shallow submucosal (n = 1), deep submucosal (n = 4), and muscle invasive (n = 1). The clinical course of all patients after PAEM was favorable. In patients who underwent additional surgery, anus preservation was achieved on the basis of the pathological results from PAEM. CONCLUSIONS: PAEM for lesions with severe fibrosis exhibiting the muscle-retracting sign appears to be both safe and useful.

    BACKGROUND: The feasibility and safety of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasms extending to the cervical esophagus currently remain unknown because of the limited number of cases. We aimed to clarify the clinical outcomes of these cases. METHODS: This was a case series study conducted at a single institution that enrolled 26 consecutive patients with superficial esophageal neoplasms extending to the cervical esophagus who underwent ESD between July 2003 and December 2015. RESULTS: En bloc and complete resection rates were both 100 % and no major intraprocedural complications occurred. Thirteen patients were treated with prophylactic steroid therapy. The incidence of postoperative stricture in patients with a circumferential mucosal defect of more than three-quarters was 72.7 %. Four patients required entire circumferential resection, with perforation occurring after endoscopic balloon dilation (EBD) in two and EBD being required for more than 1 year in the other two. CONCLUSIONS: ESD including the cervical esophagus is technically feasible. Circumferential resection may cause refractory postoperative stricture or post-EBD perforation, so needs to be avoided where possible.

    BACKGROUND AND STUDY AIMS: Endoscopic submucosal dissection (ESD) is a reliable method that can replace surgery under certain conditions. However, limited information is available on the clinical course of T1b colorectal cancer (CRC) after ESD. The aim of the study was to clarify the feasibility of ESD for T1b CRC. PATIENTS AND METHODS: Three hundred and two patients with 312 T1 CRC were identified in this retrospective cohort study. All patients were treated with ESD, other endoscopic treatments, or surgery. In this study, we (I) investigated the en bloc resection rate of ESD and (II) compared the overall survival (OS) rate for patients who underwent ESD with additional surgery (Group A) and surgery without upfront endoscopic resection (Group B) for T1b CRC. RESULTS: No significant differences were observed in the en bloc resection rates between T1b and T1a CRC (100 vs. 98.7%), but the en bloc R0 resection rate was significantly lower in T1b CRC than in T1a CRC (64.7 vs. 97.4%). Regarding complications, perforations occurred in 2.9% of patients with T1b CRC, which was not significantly different from the rate of 5.3% in patients with T1a CRC. No significant differences were observed in the OS or recurrence-free survival (RFS) curves between Groups A and B (OS rates at 5 years: 92.3 vs. 88.9%, RFS rates at 5 years: 81.4 vs. 85.3%). Similarly, the 5-year disease-specific survival (DSS) rate of Group A was identical to that of Group B (both 100%). CONCLUSIONS: ESD for T1b CRC before surgery is a possible strategy because of the low rate of complications and favorable long-term outcomes.

    BACKGROUND AND AIM: One of the challenges during peroral endoscopic myotomy (POEM) is ensuring the appropriate length of myotomy on the gastric side. To determine the appropriate distal end of the gastric myotomy, we focused on the two penetrating vessels (TPVs) found in the gastric cardia during POEM. In the present study, we evaluated whether the TPVs could serve as an accurate indicator of the appropriate distal end of the gastric myotomy. METHODS: All patients who underwent POEM between March and August 2016 were included for this study. When making the submucosal tunnel in the 5 o'clock direction into the stomach, two vessels penetrating through the circular muscle along the edge of oblique muscle in the cardia can be exposed. We designated these two vessels as TPVs. The myotomy was extended until the second TPVs was exposed. The anal end of the submucosal tunnel was confirmed by the double-scope POEM technique, and the length from the gastroesophageal junction to the anal side end of the myotomy was measured by the scale on the endoscope. RESULTS: Among 37 patients who underwent myotomy in the 5 o'clock position, TPVs were found in 34 patients (91.2%). Sufficient submucosal tunneling on the gastric side was confirmed by the double-scope POEM technique in these 34 patients. Median length of the gastric myotomy was 3.0 cm (range 2-4 cm). CONCLUSION: TPVs appears to be a simple and reliable indicator to determine the appropriate distal end of myotomy.

    Background and study aims : In order to perform peroral endoscopic myotomy (POEM) safely, retained liquid and food debris must be removed before the procedure is started. We developed a novel technique using a super-slim gastroscope, and a gastric tube to remove retained food debris in achalasia patients. In this study, the safety and efficacy of this novel technique were investigated. Patients and methods : Eleven patients with achalasia were enrolled in this study and underwent this novel method for esophageal clearance. Results:  All patients had complete clearance of the retained food debris using this method. The median procedure time (range) was 13 (6 - 30) minutes. There were no serious adverse events (AEs) and one minor AE of mucosal erythema due to mucosal suctioning. Conclusion:  This novel method for esophageal clearance is safe and effective in achalasia patients with large amounts of retained food debris.

    A female in her 70s underwent esophagogastroduodenoscopy (EGD) for screening, and a 0-IIa lesion measuring approximately 15 mm was detected in the descending portion of the duodenum. Due to the malignant potency of the lesion, endoscopic submucosal dissection (ESD) was performed. Microperforation occurred during ESD. The lesion was removed en bloc and the post-ESD ulcer bed was closed with clips. The next day, the patient had abdominal pain and computed tomography (CT) revealed a small amount of free air in the retroperitoneal space. Since there were no findings to suggest panperitonitis, conservative medical management including fasting and antibiotics was continued. Abdominal pain subsequently improved. However, EGD on the 8th day after ESD for follow-up showed shedding of the post-ESD ulcer that penetrated the retroperitoneal space. A surgical approach was not indicated because a few days may have already passed since postoperative perforation occurred and the spread of inflammation to the retroperitoneum was suspected. In an attempt to promote closure of the perforated cavity, we patched polyglycolic acid sheets and fibrin glue to the cavity wall on days 17, 18, and 20 after ESD. The formation of granulation tissue was detected in the cavity one week later. CT showed an abscess in the right retroperitoneum, for which CT-guided abscess puncture was performed. Thereafter, the cavity gradually decreased. After the initiation of oral intake on postoperative day (POD) 63, the general condition of the patient was stable and she was discharged on POD 87. Polyglycolic acid sheets with fibrin glue and CT-guided abscess puncture were useful for closing the large cavity that developed after duodenal postoperative perforation.

    Background and study aims  Endoscopic submucosal dissection (ESD) for duodenal tumors results in a high delayed perforation rate due to the thinness of the duodenal wall. In most cases with perforation after duodenal ESD, additional surgery is needed due to severe peritonitis. A newly developed procedure, laparoscopic endoscopic cooperative surgery for duodenal tumors (D-LECS), may help to avoid perforation after ESD. In our institution, patients with superficial non-ampullary duodenal epithelial tumors (SNADET) smaller than 50 mm which could not have en-bloc resection by endoscopic mucosal resection were treated with D-LECS. After a laparoscopic exposure of anterior duodenal wall of second portion, ESD was performed. Laparoscopic suturing from the serosal side of ESD site was performed for reinforcement. There were neither postoperative leakage nor other complications. Therefore, D-LECS can be performed safely and prevent perforation after ESD for SNADET. D-LECS could be selected as a treatment for SNADET which can be cured by ESD.

    BACKGROUND AND STUDY AIMS : Peroral endoscopic myotomy (POEM) is an evolving new treatment strategy for achalasia. Although several kinds of electrosurgical knives have been used in performing POEM, the best device has yet to be determined. The FlushKnife BT is a waterjet-emitting short needle-knife with a small ball tip (BT) that offers the potential to perform all aspects of POEM with a single device. In this study, we evaluated the safety and efficiency of the FlushKnife BT for POEM. PATIENTS AND METHODS:  A total of 54 consecutive patients with achalasia and other spastic esophageal motility disorders, such as jackhammer esophagus or distal esophageal spasm, who underwent POEM between January 2016 and August 2016, were included in this retrospective study. RESULTS:  The median operation time was 73.0 minutes (range 39 - 184 minutes). All procedures were completed using only the FlushKnife BT without changing to any other electrosurgical instrument. The median number of additional submucosal injections with an injection needle was 0 (range 0 - 1). Endoscopic vessel sealing was performed a mean of 3 times (range 0 - 7). The median number of bleeding episodes requiring treatment with hemostatic forceps was 0 (range 0 - 5). There were no significant adverse events. Seven of 52 patients (13.5 %) reported symptoms of gastroesophageal reflux disease such as heartburn or acid reflux at 3 month follow-up. CONCLUSIONS:  The FlushKnife BT enabled POEM to be performed with very few device exchanges, either for re-injection or to control intraoperative bleeding. In this uncontrolled case series, the ability of the FlushKnife BT to perform nearly all aspects of the POEM procedure seems to make it particularly well suited to this procedure.

    A 66-year-old woman presented to us with malaise, anorexia and rectal mucous discharge, and her laboratory data showed severe hyponatremia, hypokalemia, hypochloremia and renal failure. Computed tomography revealed massive occupation of the rectum by a large tumor. Colonoscopy revealed a mucus-rich villous tumor in the rectum. As there were no other factors that could cause an electrolyte disorder, she was diagnosed with McKittrick-Wheelock syndrome (MWS). The current standard treatment for MWS is partial surgical colectomy. However, surgeries are invasive and postoperative complications sometimes become an issue. After confirming no signs of submucosal invasion of the tumor by magnifying chromoendoscopic examination, endoscopic submucosal dissection (ESD) was indicated. The tumor was completely removed en bloc without adverse events. The histology showed a mucosal adenocarcinoma containing a villous component, 24.5 x 17.0 cm in size. This removal dramatically improved the patient's symptoms and the electrolyte abnormalities without medication. Although several sessions of endoscopic balloon dilation were required to treat postoperative stricture, she has been symptom-free and had no recurrence for 4 years after treatment. We experienced a case of MWS treated by ESD instead of surgery. ESD should be feasible and beneficial for the treatment of MWS.

    BACKGROUND AND STUDY AIMS: During colorectal endoscopic submucosal dissection (ESD), the feature of a muscle layer being pulled toward a neoplastic tumor is sometimes detected. We call this feature the muscle-retracting sign (MR sign). The aim of this study was to evaluate whether the MR sign is associated with particular types of neoplastic lesions and whether it has any clinical significance for ESD sessions. PATIENTS AND METHODS: A total of 329 patients underwent ESD for 357 colorectal neoplasms. The frequency of positivity for the MR sign was evaluated in different morphologic and histopathologic types of neoplasm. The success rate of complete resection and the incidence of complications were also evaluated according to whether lesions were positive or negative for the MR sign. RESULTS: The rates of positivity for the MR sign in the various lesion types were as follows: laterally spreading tumor - granular nodular mixed type (LST-G-M), 9.6 %; laterally spreading tumor - granular homogeneous type (LST-G-H) and laterally spreading tumor - nongranular type (LST-NG), 0 %; sessile type, 41.2 %. The resection rate was 100 % (329 /329) in lesions negative for the MR sign; however, it was 64.3 % (18 /28) in lesions positive for the MR sign, which was significantly lower (P < 0.001). CONCLUSIONS: The MR sign was present only in some protruding lesions, and more importantly, it was associated with a high risk of incomplete tumor removal by ESD. Our data indicate that lesions positive for the MR sign lesions should be dissected with great caution; alternatively, based on the features of the individual case, a switch to surgery should be considered for the benefit of the patient.

    The development of endoscopic submucosal dissection (ESD) has enabled en bloc resection of lesions regardless of size and shape. However, ESD of colorectal tumors is technically difficult. Early stage colorectal tumors can be removed by endoscopic mucosal resection (EMR) but larger tumors may require piecemeal resection. Therefore, ESD with snaring has been proposed for more reliable EMR and easier ESD. This is a good option to fill the gap between EMR and ESD, and a good step to the introduction of full ESD.

    Conventionally, long-segment Barrett's esophagus (LSBE) has been considered a high-risk background for the occurrence of Barrett's adenocarcinoma in Western countries, and random biopsy has been proposed for surveillance, aiming to detect early cancer. However, accurate detection of a lesion and diagnosis of the expansion are difficult by this blind method. Herein, we report a case of early Barrett's adenocarcinoma derived from LSBE that was successfully detected by narrow-band imaging with magnifying endoscopy.

    BACKGROUND: Recently, early detection and early treatment of the colorectal cancer have been enabled by the improvement of endoscopic diagnosis and introduction of new techniques. In Japan, although Japan Polyp Study is running, there is no standard strategy concerning the post-polypectomy colonoscopic surveillance yet. Post-polypectomy colonoscopic surveillance is so far entrusted to each institute or each gastroenterologist at present. MATERIAL AND METHOD: To analyze the present states of the surveillance after polypectomy in Japan, we performed questionary survey and compared them with the results in U.S. and U.S. Multisociety Task Force on colorectal Cancer. A simple random sample of 132 doctors who engaged in a digestive organ disease in plural institutes was obtained. RESULT: Many doctors recommend surveillance every around 1 year regardless of the kind of the polyp. Doctors in Japan tend to recommend postpolypectomy colonoscopic surveillance more frequently than that recommended U.S. Multisociety Task Force on colorectal Cancer. Furthermore in all types of polyps except for 12 mm tubular adenoma with high grade dysplasia, the majority of doctors in Japan recommend post-polypectomy colonoscopic surveillance more frequently than American doctors. Significant difference was found in surveillance of hyperplastic polyp among doctors with 1 to 5 years experience and those with more than 6 years. CONCLUSION: It has been shown that surveillance intervals varies substantially in each doctor. The agreement of the surveillance program in Japan is necessary to standardize the strategy for the post-polypectomy surveillance of the colon.

    第83回日本消化器内視鏡学会総会, May 2012, Japanese, 日本消化器内視鏡学会, 東京, 【目的】ESDの登場で表層拡大型食道癌に対して、内視鏡治療の適応が拡大してきている。しかしながら、術前診断の限界や術後狭窄などの問題が残され、未だ標準治療には至っていない。そこで、当院での表層拡大型食道癌に対するESDの適応と問題点について、検討したので報告する。【方法】対象は2008年4月から2011年9月までの食道ESD244病変のうち、5cm以上の表層拡大型31病変。術前にNBI併用拡大内視鏡、EUS、造影CTによる精査を行った後、ESDを行った。また、3/4周以上の切除となった病変には予防的内視鏡的バルーン拡張術あるいはステロイド局注を行った。【成績】一括切除率は100％で、偶発症は1例に縦隔気腫を認めたのみであった。術前にEP/LPM、MM/SM1、SM2と診断した病変は、それぞれ61.2％（19/31）、35.5%（11/31）、3.2, Domestic conference
