Endoscopic submucosal dissection using a novel grasping type scissors forceps

Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure that is associated with a high complication rate. The shortcoming of this method is the difficulty in fixing the knife to the target lesion. This difficulty can lead to unexpected incision, resulting in major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using an electrosurgical current. The ESD procedure using the GSF was carried out in an animal model (resected porcine stomachs in vitro). After marking the lesion and injecting a solution into the submucosa, the lesion was separated from the surrounding normal mucosa following complete incision around the lesion using the GSF. A piece of submucosal tissue was grasped and cut with the GSF using an electrosurgical current to achieve submucosal exfoliation. ESD using the GSF was carried out safely and easily without unintentional incision. ESD using GSF appears to be an easy, safe, and technically efficient method for resecting gastrointestinal neoplasms.     

Grasping-forceps-assisted endoscopic submucosal dissection using a novel irrigation cap-knife for large superficial early gastric cancer

The technique of endoscopic submucosal dissection (ESD) needs special skills and involves a long procedure. We therefore developed a new type of dissection knife, the irrigation cap-knife (the Kume cap-knife attachment, which uses a fixed snare), that facilitates ESD by just sliding over the muscle layer with a coagulating current. The ESD procedure using the irrigation cap-knife was performed in seven patients with intramucosal gastric cancer. The tumor was separated from the surrounding normal mucosa using the insulated-tip knife. Submucosal dissection was then performed by pushing our device along the muscle layer while applying a coagulating current, at the same time as a grasping forceps, deployed through the accessory channel, was used to push the lesion away from the muscle layer. The rate of en bloc resection was 100% (7/7). The irrigating cap-knife was extremely useful for ESD of large intramucosal cancers in the stomach.     

内镜黏膜下剥离术治疗早期胃癌扩大指征的安全性分析

目的 探讨内镜黏膜下剥离术治疗早期胃癌扩大指征的安全性。 方法 回顾性分析该院2005年12月~2013年5月行胃癌根治术的早期胃癌病理资料,筛选出符合内镜黏膜下剥离术扩大指征的病例,比较不同浸润深度、分化类型的淋巴结转移情况。 结果 入组157例患者中发生淋巴结转移13例。黏膜内癌（m癌）、黏膜肌层癌（mm癌）、分化型黏膜下层癌（sm1癌）的淋巴结患者转移率分别为0.0%（0/18）、6.6%（4/61）、11.5%（9/78）,3组间比较（χ2=2.954,P =0.228）、m癌与mm癌比较（χ2=1.243,P =0.265）、mm癌与分化型sm1癌比较（χ2=1.002,P =0.317）,差异均无显著性（P >0.05）。分化好与分化差的淋巴结转移率分别为2.3%（2/86）、15.5%（11/71）,比较（χ2=8.879,P =0.003）,差异具有显著性（P <0.05）。 结论 大部分符合扩大指征的早期胃癌行内镜黏膜下剥离术治疗是安全可行的,黏膜内癌更为可靠,黏膜下癌因缺乏精确的术前评价体系,需慎重选择内镜下治疗,尤其是分化程度差者,建议行胃癌根治术。

Clinical features and outcomes of delayed perforation after endoscopic submucosal dissection for early gastric cancer

Perforation is a major complication of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). However, there have been no reports on delayed perforation after ESD for EGC. We aimed to elucidate the incidence and outcomes of delayed perforation after ESD. Clinical courses in 1159 consecutive patients with 1329 EGCs who underwent ESD were investigated. Delayed perforation occurred in six patients (0.45?%). All these patients had complete en bloc resection without intraoperative perforation during ESD. Five of six perforations were located in the upper third of the stomach, while one lesion was found in the middle third. Symptoms of peritoneal irritation with rebound tenderness presented within 24?h after ESD in all cases. One patient did not require surgery because the symptoms were localized, and recovered with conservative antibiotic therapy by nasogastric tube placement. The remaining five patients required emergency surgery. There was no mortality in this case series.

Endoscopic submucosal dissection for residual/local recurrence of early gastric cancer after endoscopic mucosal resection

BACKGROUND AND STUDY AIMS: Endoscopic mucosal resection (EMR) is a widely accepted treatment for early gastric cancer; however, incomplete resection with residual local disease and recurrences continues to be a difficult problem. The aim of this study was to evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for residual/local recurrent early gastric cancer lesions after EMR. PATIENTS AND METHODS: The en bloc resection rate, histologically complete resection rate, complications, and local recurrence were assessed in 15 patients who underwent ESD for residual/local recurrent early gastric cancer lesions after EMR. RESULTS: The nonlifting sign after injection of a glycerin solution was positive due to scar formation in all cases. En bloc resection was attempted in all cases, with a complete resection rate of 93.3 % (14 of 15). The lesion was completely resected with histologically adequate margins in the 14 patients who received complete en bloc resection. The average operation time was 85.4 +/- 52.9 min, and the mean follow-up period for all patients was 18.1 +/- 7.4 months. Major bleeding during the procedure in one case was the only complication (one of 15, 6.7 %). None of the patients experienced recurrence of early gastric cancer after ESD. CONCLUSIONS: ESD appears to be a safe and effective treatment for residual/local recurrent early gastric cancer lesions after EMR, and it is useful for histological confirmation of successful treatment.
