Endoscopic mucosal resection and full thickness resection with complete defect closure for early gastrointestinal malignancies

BACKGROUND AND STUDY AIMS: We developed a new endoscopic technique, the endoscopic full-thickness resection (EFTR) and endoscopic complete defect closure (ECDC), for the treatment of early gastrointestinal malignancies. PATIENTS AND METHODS: Two rectal and one duodenal carcinoid were treated by EFTR with ECDC and resectability, complications and pathological findings were evaluated. RESULTS: In all cases, the lesion was completely resected without serious complications. The histology of the specimen also confirmed complete resection of the tumor. CONCLUSIONS: This technique has great potential for the treatment of early gastrointestinal malignancies. Preliminary results have shown that early malignant gastrointestinal lesions can be safely and completely resected by EFTR with ECDC.

Multiple gastric angiolipomas: A case report

BACKGROUND Angiolipoma is a benign tumor and is generally found in subcutaneous tissues.Angiolipomas are rare in the gastrointestinal tract,including the stomach.Preoperative diagnosis of the tumor is difficult,although there are several radiological examinations such as computed tomography and endoscopic ultrasound.CASE SUMMARY We report a 24-year-old Chinese man with multiple gastric angiolipomas,with a positive stool occult blood examination. Endoscopic biopsy only showed nonspecific inflammation. Histological examination of the specimen by endoscopic snare resection showed that the tumor consisted of adipose tissues and blood vessels. We also performed a literature review. After the use of proton pump inhibitor,the fecal occult blood test was negative. Due to the difficulty of resecting multiple lesions in the stomach completely and the benign characteristics of angiolipoma,we chose to have regular upper gastrointestinal endoscopy evaluation of the lesion. No evidence of significant change in lesion size was detected after 3-years follow-up.CONCLUSION Gastric angiolipoma is rare,and benign neoplasm should be considered when lesions occur submucosally in the gastrointestinal tract.

Gastric mixed adenoma-neuroendocrine tumor: A case report

BACKGROUNDGastric mixed adenoma-neuroendocrine tumors (NETs) are quite rare. In the 2019 world health organization classification of tumors of the digestive system, these were designated as a combination of grade 1 or grade 2 NETs and adenomas or tubular adenomas. There are no treatment guidelines for these tumors, and pathological and clinical studies are ongoing. Herein, we review previous case reports and present a case of gastric mixed adenoma-NET.CASE SUMMARYA 66-year-old man underwent gastrointestinal endoscopy for the evaluation of upper abdominal pain. Histopathological examination of the biopsy specimen indicated the possibility of gastric cancer. A histopathological examination by endoscopic submucosal dissection showed a mixed adenoma-NET that was completely excised by endoscopic submucosal dissection. No recurrence was observed on gastrointestinal endoscopy at the 6-mo follow-up.CONCLUSIONClinicians'' awareness of this rare tumor is important for its timely diagnosis and treatment.     

Intraoperative gastrointestinal endoscopy in the management of occult gastrointestinal bleeding.

Intraoperative gastrointestinal endoscopy has become an increasingly valuable diagnostic and therapeutic adjunct in the management of a variety of complicated problems in surgical patients. At the Medical College of Georgia, intraoperative gastrointestinal endoscopic technics have been successfully used to locate the site and cause of occult gastrointestinal bleeding; to diagnose, biopsy, and, when appropriate, resect lesions during operations conducted for other pathologic processes; to gain endoscopic access for resection of lesions otherwise inaccessible (endoscopically) by virtue of intestinal distortion caused by adhesions; to guide the operating surgeon to an area of resectable disease through dense adhesions secondary to multiple previous laparotomies; and to enhance diagnosis at laparotomy. The value of intraoperative gastrointestinal endoscopy in lesions resulting in occult gastrointestinal hemorrhage and the value of combined radiographic and intraoperative endoscopic technics in diagnosing and managing occult GI bleeding are discussed.
