Minimally invasive management of large duodenal lipoma: endoscopic submucosal dissection.

Project description:ObjectiveThis study was performed to compare the clinical outcomes of large duodenal lipomas (DLs) of ≥2 cm between endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFTR).MethodsThis retrospective study included patients who underwent endoscopic resection of large DLs from June 2017 to March 2021 at our hospital. Clinicopathologic features, clinical outcomes, and follow-up endoscopy findings were retrospectively reviewed.ResultsTwenty-three patients (12 men) with a mean age of 57.4 years were included. The median tumor size was 28.4 ± 13.3 mm. ESD was performed in 19 patients, and EFTR was performed in 4. Complete resection was achieved in 21 patients. The operative time and postoperative hospital stay were significantly shorter in the ESD than EFTR group. Four patients in the EFTR group developed a fever; no other adverse events occurred. No patients required surgical intervention. During the average follow-up of 21.1 months, no residual tumor, recurrence, or metastasis was observed.ConclusionBoth ESD and EFTR provide minimally invasive, localized treatment of selected DLs. ESD might have some advantages in resecting large DLs in terms of procedure time and hospitalization.

Successful esophageal endoscopic submucosal dissection with intraoperative release of stenosis due to previous endoscopic submucosal dissection scarring.

Project description:Endoscopic submucosal dissection (ESD) is the standard endoscopic treatment for early esophageal cancer. Esophageal stricture often occurs at the site of ESD for large lesions. When treating a metachronous lesion appearing at the severe stricture, it may be difficult to negotiate a conventional endoscope through the stricture. Using a thin endoscope may be a useful strategy for such lesions, though ESD using a thin endoscope is challenging because of poor maneuverability. Herein, we report a case of successful ESD for early esophageal cancer at the severe stricture, using a conventional endoscope. A 72-year-old man with a previous history of ESD for esophageal cancer and a post-ESD esophageal stricture was referred to our hospital for metachronous early esophageal cancer. The lesion, 10 mm in diameter, was located at the stricture with a slight distal extension. Conventional endoscopes could not be negotiated through stricture. Therefore, submucosal dissection was performed from the oral to the anal aspect of the lesion, as far as possible. After completion of submucosal dissection of the oral aspect of the lesion and part of the lesion located on the stricture, the severe stricture was released, allowing the passage of conventional endoscope, and ESD of the entire lesion was completed en bloc. Histopathological examination showed squamous cell carcinoma, pT1a-LPM. Stricture due to scarring may occur during the regeneration process of the defective mucosa, muscularis mucosa, and submucosal layer. Therefore, incision and dissection of the contracted mucosa, mucularis mucosa, and submucosal layer would release the stenosis.

Huge liposarcoma of esophagus resected by endoscopic submucosal dissection: case report with video.

Project description:Liposarcoma is one of the most common soft tissue sarcomas occurring in adults, but it rarely occurs in the gastrointestinal tract and more uncommonly in the esophagus. To the best of our knowledge, there are only 19 reported cases of esophageal liposarcoma in the literature published in English language up to the year 2008, and they were all treated by surgical methods. Here, we report a case of primary liposarcoma of the esophagus which was treated with endoscopic submucosal dissection (ESD). ESD was well tolerated in this patient, suggesting that it may be a therapeutic option for primary esophageal sarcomas.

Successful traction-assisted endoscopic submucosal dissection using dental floss and a clip for a huge superficial nonampullary duodenal epithelial tumor with severe fibrosis (with video).

Project description:Recently, traction-assisted endoscopic submucosal dissection (ESD) using a clip and thread was reported as useful for treating lesions in the esophagus, stomach, and colorectum in terms of shortening the duration of the procedures and reducing the risk of intraoperative perforation. However, no traction method using the thread and clip for duodenal ESD as described in this article has been reported to date. We report a case in which traction-assisted ESD using dental floss and a clip was successfully performed on a huge superficial nonampullary duodenal epithelial tumor accompanied by severe fibrosis caused by preoperative biopsies. A 65-year-old woman had a 55-mm flat-elevated tumor in the second part of the duodenum. Severe fibrosis of the submucosal layer was expected due to repeated biopsies at the same site by the patient's previous endoscopist. We selected ESD for this lesion, and the initial incision was started from the side proximal to the lesion, but it was difficult to insert the scope under the submucosal layer directly beneath the biopsy scar. Therefore, traction with an endoclip and dental floss was performed to lift the lesion. Excellent traction allowed safe resection of the fibrotic part under accurate visual observation. Finally, the lesion was resected en bloc without adverse events. Traction-assisted ESD using dental floss and a clip is likely to be an effective adjunctive technique for quick, safe, and successful resection of lesions in the duodenum on which it is difficult to perform ordinary ESD and that have a high probability of intraoperative perforation and massive bleeding.

Successful Endoscopic Resection of Primary Rectal Mucosa-Associated Lymphoid Tissue Lymphoma by Endoscopic Submucosal Dissection: A Case Report.

Project description:Mucosa-associated lymphoid tissue (MALT) lymphoma arises in extra-nodal sites from the malignant transformation of B lymphocytes that are mainly triggered by infection or autoimmune process. MALT lymphoma is frequently detected in the gastrointestinal tract. As the causal relationship between Helicobacter pylori (H. pylori) infection and gastric MALT lymphoma, it was well-established that early-stage gastric MALT lymphoma could be cured by H. pylori eradication, and about 50-95% of cases achieved complete response with anti-H. pylori treatment. Compared to the stomach which is the most involved site due to the high prevalence of H. pylori infection, the colorectum is rarely affected. Primary rectal MALT lymphoma is a rare malignancy, and there are no specific therapeutic strategies so far. Here we report a case of rectal MALT lymphoma successfully resected by endoscopic submucosal dissection (ESD). ESD serves as a novel strategy to cure small localized rectal MALT lymphomas to avoid unnecessary surgery or chemo-radiotherapy.
