This article from the American Society for Gastrointestinal Endoscopy (ASGE) provides a full description of the methodology used to inform the final guidance outlined in the accompanying summary and recommendations article for strategies to manage endoscopically placed gastrostomy tubes. This article was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework and specifically addresses the utility of PEG versus interventional radiology–guided gastrostomy (IR-G), the need for withholding antiplatelet and anticoagulant medications, appropriate timing to initiate tube feedings, and appropriate selection of the gastrostomy technique in patients with malignant dysphagia. In patients needing enteral access, the ASGE suggests PEG as the preferred technique for initial gastrostomy over IR-G. The ASGE recommends that tube feeding can be safely started within 4 hours of the gastrostomy without the need for an intentional delay. The ASGE suggests that a PEG can be performed without the need to withhold antiplatelet medications. In patients on anticoagulants who need to undergo PEG placement, the ASGE suggests that the periprocedural management of anticoagulants should be based on a multidisciplinary discussion with the patient regarding the risk of bleeding versus cardiovascular adverse events. In patients with malignant dysphagia, either transoral “Pull” PEG or transcutaneous “Direct” PEG can be performed for initial enteral access.

We report a patient with history of recurrent invasive rectal adenocarcinoma complicated by obstructive uropathy requiring nephro-ureteral catheter placement. Two years later during a regular catheter exchange, the patient developed unusually bloody urine raising suspicion for possible vascular injury. CT angiogram and conventional angiogram were negative. However, an antegrade nephrostogram revealed a fistulous communication between the right ureter and the right internal iliac artery. Subsequently, the artery was sacrificed using detachable coils. We discuss the rare encounter of a silent arterio-ureteral fistula, the value of antegrade nephrostogram as a diagnostic tool, and the management options in such scenario.

Abstract Background Chylothorax is a rare complication of pediatric cardiac operations that occurs more frequently in children with Noonan syndrome, a genetic disorder associated with cardiac defects and lymphatic anomalies. Case presentation We report a case of postoperative chylothorax in a 6-month-old infant with Noonan syndrome where multimodality lymphatic imaging guided management was followed. Drainage patterns of the lymphatic capillaries in the lower and upper extremities were visualized during near-infrared fluorescence lymphatic imaging (NIRFLI). Dynamic magnetic resonance lymphangiography (MRL) further identified the site of leakage in the thoracic duct and subsequently guided surgical intervention. Conclusions Application of multimodality imaging allows for greater individualization of treatment and should be considered in patients with complex cases such as those with syndromes associated with a higher incidence of chylothorax.

Endoscopic retrieval of embedded, proximally migrated, or fractured plastic biliary stents may be technically challenging and sometimes unsuccessful. Percutaneous transhepatic techniques have previously been described to assist in such challenging cases. Here in, we describe a difficult case in which all commonly described endoscopic and percutaneous techniques failed to retrieve a proximally migrated, fractured, and looped plastic biliary stent. We finally successfully retrieved the plastic forceps after off-label utilization of rigid bronchial forceps via a percutaneous transhepatic approach. We describe the technique utilized in detail and this appears to be the first description of this off-label use in this challenging scenario.

Spontaneous arterial aneurysms of the hand are uncommon but are well-described in the adult population. In the pediatric population, however, congenital or true aneurysms of the hand are exceptionally rare. A case report and a literature review were performed for published cases of arterial aneurysms of the hand in the pediatric population. A 13-month-old child presented with an aneurysm of the common digital artery and underwent surgical excision without need for reconstruction. Literature review found 13 documented cases. Patient characteristics and management strategies were summarized. There are very few documented cases of hand arterial aneurysms in the pediatric population, with our patient being the third youngest ever reported. No cases were associated with hereditary disease, and aneurysm excision was performed in all cases. Our report highlights the need to include arterial aneurysm in a differential diagnosis when evaluating a pediatric patient with a palpable hand mass.

Percutaneous renal biopsy with ultrasound guidance is a helpful procedure regularly performed to obtain renal tissue diagnosis for rejection in the postrenal transplant setting; however, it is not without risks. We report the case of a 42-year-old male with end stage renal disease who developed a subcapsular hematoma, with subsequent hypertension and renal failure, compatible with acute page kidney as a complication of the renal biopsy. The ultrasound images demonstrated classic imaging appearances which all diagnostic and interventional radiologists should be aware of. The patient was managed successfully with conventional open surgical evacuation of the hematoma with return to baseline laboratories and vital signs after the procedure.
