Transhepatic Approach for Retrograde D2 Duodenal Stent Placement: New Technique and Case Series

Trans-Biliary Gastric Outlet Recanalization and Stenting: A Case Report

Gastric ischemia is a condition of hypo-perfusion associated with hypotension, vasculitis, and thromboembolism. We report a case of a gastric outflow obstruction due to sizeable visceral artery thrombo-embolism leading to the ischemic conclusion, the frailty, multiple comorbidities deeming general anesthesia (GA) risky, and the patient’s decision not to have an open surgery under GA. Invasive procedures in patients with similar profiles like our patient are usually not risk-free, this leads the intervention radiology team to believe a minimally invasive procedure while avoiding GA might be optimal. A 63-year-old female with multiple comorbidities came eight weeks after significant surgery complaining of severe acute epigastric pain, abdominal distention and rigidity, and persistent vomiting. Further investigations showed obstruction in the gastric antrum and pyloric canal. Three separate endoscopic attempts to find and cross the stricture failed. Firstly, gastrostomy access was established, but due to the stomach being massively distended, passing a guidewire through the pylorus failed despite using multiple hydrophilic wires and pre-shaped catheters, this is due to the collapsed pylorus. Subsequently, two attempts under ultrasound guidance to puncture the duodenal bulb and pass a wire and catheter through the antrum stricture were unsuccessful, and another attempt was considered of high risk. An alternative approach through the gallbladder was established, and cholangiography was performed to delineate the anatomy. Then an approach through the right hepatic duct and ampulla of Vater was successfully performed. The attempted passage through the stricture was successful. The dilation was successful, and the patient tolerated both fluid and solids orally. Due to having such a frail patient, interventions of minimal invasiveness and favorable outcome are welcomed. This case report suggests that this technique showed satisfactory results and achieved the goal to improve the overall quality of life where the patient had a good oral intake with no post-operation complications.

Recent Updates in Gastrointestinal Stent Placement from the Esophagus to the Colon: A Radiological Perspective

Fluoroscopic-guided stent placement has become an advantageous treatment option for diverse gastrointestinal disorders. In addition to palliative stent placement in patients with inoperable cancers, stenting has gradually expanded to other conditions, including as a bridge to surgery, as well as in patients' benign lesions and anastomotic strictures or leaks. This narrative review describes the indications, efficacy and safety of stent placement from the esophagus to the colon, including current recommendations, recent updates, and novel stents.
