Impact of the COVID-19 Outbreak on Anesthesiologist Assistance for Endoscopic Procedures
Background/Aims: The coronavirus disease 2019 (COVID-19) outbreak has modified the activities of endoscopy units worldwide. Herein, we investigated the impact of the COVID-19 outbreak on anesthesiologist assistance for endoscopic procedures in Lombardy, Italy. Methods: A questionnaire concerning anesthesiologist assistance provided from October 26 to December 6, 2020, in comparison with the same period in 2019, was sent to endoscopic units in Lombardy. Results: Approximately 54% (34/63) of the units responded. A reduction in the number of all endoscopies (-33.5%; 18792 in 2020 vs. 28264 in 2019) and anesthesiologist-assisted endoscopies (-15.3%; 2652 in 2020 vs. 3132 in 2019) was reported. A greater reduction in anesthesiologist assistance was observed in government community units (-29.5%) than in academic (-14%) and private community units (-4.6%). Among all units, 85% reported a reduction in anesthesiologist assistance; 65% observed a delay/cancellation of procedures; 59%, a restricted patient selection; 17%, the need to transfer some patients to other hospitals; and 32%, a related worsening of procedure quality. Conclusion: The COVID-19 pandemic compromised the anesthesiologist assistance for endoscopic procedures in Lombardy, which worsened the procedure quality mainly in government community units. The COVID-19 “stress test” suggests a more balanced allocation of anesthesiologic resources in the future
Endoscopic ultrasound-guided fine-needle aspiration for suspected malignancies adjacent to the gastrointestinal tract
Advanced endoscopic interventions on the pancreas and pancreatic ductal system: a primer for radiologists
Abstract In recent years, technological advancements including endoscopic ultrasound (EUS) guidance and availability of specifically designed stents further expanded the indications and possibilities of interventional endoscopy. Although technically demanding and associated with non-negligible morbidity, advanced pancreatic endoscopic techniques now provide an effective minimally invasive treatment for complications of acute and chronic pancreatitis. Aiming to provide radiologists with an adequate familiarity, this pictorial essay reviews the indications, techniques, results and pre- and post-procedural cross-sectional imaging appearances of advanced endoscopic interventions on the pancreas and pancreatic ductal system. Most of the emphasis is placed on multidetector CT and MRI findings before and after internal drainage of pseudocysts and walled-off necrosis via EUS-guided endoscopic cystostomy, and on stent placement to relieve strictures or disruption of the main pancreatic duct, respectively in patients with chronic pancreatitis and disconnected pancreatic duct syndrome
Diagnostic Accuracy of Endoscopic Ultrasonography in Selecting Patients for Endoscopic Submucosal Dissection for Early Gastrointestinal Neoplasms
Tumor invasion depth and lymph node metastasis determine the prognosis of gastrointestinal (GI) neoplasms. GI neoplasms limited to mucosa (m1 or m2) and superficial submucosa (sm1) can be treated effectively with minimally invasive endoscopic therapy, while the deep invasion of the submucosa (sm2 or sm3) is associated with lymph node metastasis, and surgical resection is required. Correct staging is therefore crucial for preoperative evaluation and planning. Endoscopic ultrasonography (EUS) can be used to detect the depth of invasion due to its close proximity to the lesion. The diagnostic accuracy of EUS, when compared to conventional endoscopic staging, is debated as it can under- or overstage the lesion. We aim in this study to determine if EUS can accurately differentiate mucosal from submucosal GI neoplasms to select patients with early GI lesions for endoscopic submucosal dissection (ESD) or surgery. From March 2014 to February 2022, 293 patients with early superficial GI neoplasms were admitted to our endoscopic unit for EUS staging. To evaluate the accuracy of EUS, we compared the preoperative EUS findings with the definitive histopathologic findings on the resected specimen. Overall, 242 of 293 lesions were correctly staged by EUS (82.59%). In the evaluation of submucosal invasion or deeper, EUS understaged 38 of 293 (12.96%) and overstaged 13 of 293 (4.43%) lesions. EUS has excellent accuracy in staging superficial GI neoplasms; its use is highly recommended before ESD since it can also detect lymph node metastases around the lesions, thus changing the indication from ESD to surgery
