Pneumothorax as a complication of ESD

Microperforation after colonic endoscopic submucosal dissection, air in 5 separate locations

Endoscopic submucosal dissection (ESD) and endoscopic mucosal dissection (EMD) are recognized treatment procedures for mucosal lesions. There will always be a risk for complications even if they are performed by experienced specialists. In this study, we aimed to present a 58-year-old male patient in whom lesion was detected in the proximal part of the descending colon during a colonoscopy. Histopathological examination of the lesion revealed intramucosal carcinoma. The lesion was removed by ESD but after the intervention, bilateral pneumothoraxes, pneumoperitoneum, pneumoretroperitoneum, pneumomediastinum and pneumoderma complications observed. It is quite unlikely to encounter all of these complications together in one patient. In this paper, we would like to highlight the potential for complications after ESD, even for the rare and unexpected ones, to contribute to their recognition and treatment.

Pneumothorax following endoscopic submucosal dissection of a rectal tumor

Endoscopic submucosal dissection is a useful alternative to endoscopic mucosal resection and surgery for en bloc resection of colorectal tumors. However, the technique is considered to be difficult, and potential complications include perforation and postoperative bleeding. In this case report, we present a case of a 63-year-old woman who developed pneumothorax after endoscopic submucosal dissection of a rectal tumor.

Management of complications following endoscopic submucosal dissection for gastric cancer

Endoscopic treatment should be considered for early gastric cancer (EGC) and gastric precancerous lesions. Endoscopic submucosal dissection (ESD) was developed for en bloc removal of a large gastric neoplasm and has been developed following improvements in electrical equipment for hemostasis and dissection and with advances in various knives, hemostatic forceps and endoscopic equipment. ESD is currently the treatment of choice for precancerous lesions or EGC showing mucosal invasion. Hemorrhage and perforation are major complications of ESD for EGC. We describe the complication of ESD procedures in gastric lesions for endoscopists who are relatively inexperienced in ESD and who may lack optimal access to ESD education and facilities.
