False positive retroaortic left circumflex coronary artery in a patient with atrial septal defect

Retroaortic course of coronary artery is a relative contraindication for device closure of an atrial septal defect. In this brief report, we demonstrate, for the first time, inferior aortic recess mimicking retroaortic left circumflex coronary artery in a patient with atrial septal defect. This distinction is important to avoid spurious diagnosis of anomalous coronary artery denying patient a chance of nonsurgical closure of atrial septal defect.     

Multiarticular Tophaceous Gout with Severe Joint Destruction: A Pictorial Overview with a Twist

Tophi are the visible dermatological signs of gout. A case of tophaceous gout in a middle-aged man with no other metabolic derangement is being presented with multiple tophi on the hands and feet overlying joints as well as on the fingers and toes. We thought it to be of educational value to demonstrate needle-like crystals of urate by polarizing microscopy. X-rays of hands and feet showed dramatic destructive changes. The patient presented with mottled hypopigmentation on anterior and posterior knees and dorsa of hands and feet where he applied hot “aankda” leaves and covered them with bandage resulting in irritant dermatitis with postinflammatory hypopigmentation. This proved to be a red herring in this case.     

Efficacy of the Za self-expandable metal stent for palliation of malignant biliary obstruction

BACKGROUND: The efficacy and safety of the uncoated self-expandable Za metal stent for palliation of malignant distal biliary obstruction was prospectively analyzed. METHODS: Twenty-one patients with unresectable malignant tumors involving mid to distal common bile duct who presented with obstructive jaundice underwent endoscopic implantation of an uncoated self-expandable metal stent. Technical success with stent placement, adverse events, patient survival, duration of stent patency, and device performance were analyzed. RESULTS: Endoscopic biliary stenting was successful in all patients. No adverse events were encountered. The mean follow-up period of the 21 patients was 128 days (range, 3-263): 14 died of progressive disease at mean of 81 days (range, 3-210), 3 remain alive (at days 239, 250, and 263), and 4 were lost to follow-up (at days 90, 91, 92, and 116). The mean duration of stent patency was 249 days. Tumor ingrowth was observed in one patient (5%). Minor technical problems were encountered in 3 patients: 1 proximal deployment, 1 distal deployment, and difficulty associated with the delivery system in 1. CONCLUSIONS: The Za-metal stent provided effective palliation for patients with inoperable malignant biliary tumors. Although minor technical problems were encountered with stent deployment, the overall stent patency, efficacy, and safety profile appear satisfactory.     

Endoscopic management of pancreatic pseudocysts and walled-off pancreatic necrosis: A two-decade experience

Aim

To determine long-term outcome of endoscopic management of pancreatic pseudocyst/walled-off pancreatic necrosis (WOPN) without necrosectomy.

Methods

One-hundred and sixty-five pancreatic pseudocysts/WOPN managed endoscopically over a period of 22 years were analyzed retrospectively for technical success, complications, and recurrence.

Results

Symptomatic 118 males and 47 females with mean age of 35.8 years were included. Alcohol was the most common etiology (41.2 %). Transmural endoscopic drainage was done in 144 patients, while 21 patients underwent transpapillary drainage. All the patients were subjected to contrast computed tomography (CT) abdomen or routine/Doppler ultrasound. Endoscopic ultrasound was done in last 11 patients. One or two double pigtail 7 Fr stents were placed when clear watery fluid came out from cyst (130 patients, 78.8 %), and nasocystic drainage (NCD) tubes were placed in addition to two 7 Fr stents when there were frank pus, thick dark fluid, or solid components inside the cyst (35 patients). All these patients settled on this treatment. Thirty-three of 35 patients of WOPN could be managed endoscopically without necrosectomy. Complications occurred in 9.2 % of pseudocysts and 40 % of WOPN. Thirty-five patients were followed up for more than 5 years (3 patients more than 10 years), and 130 patients were followed up for up to 5 years. Recurrence occurred in 8.1 % of pseudocysts and 5.7 % of WOPN.

Conclusion

Majority of pancreatic pseudocysts/WOPN can be managed with endoscopic drainage without necrosectomy with high success, low complication, and recurrence rates.
