Using the Rendezvous Technique Through Choledochoduodenostomy for Malignant Biliary Obstruction.

Endoscopic transpapillary biliary stenting via endoscopic retrograde cholangiopancreatography is the preferred therapy for benign and malignant distal biliary obstruction. In cases of failed endoscopic retrograde cholangiopancreatography, endoscopic ultrasound-guided choledochoduodenostomy has been shown to be as effective as percutaneous methods with an improved safety profile. Despite its efficacy, it is complicated by stent occlusion in 9%-26% of cases. To our knowledge, this is the first case in which biliary obstruction was relieved by performing a rendezvous procedure utilizing a pre-existing choledochoduodenostomy.

Endoscopic ultrasound-guided portal pressure gradient measurement: a systematic review and meta-analysis.

Background: Endoscopic ultrasound-guided portal pressure gradient measurement (EUS-PPG) is a new modality where the portal pressure is measured by directly introducing a needle into the hepatic vein and portal vein. This is the first systematic review and meta-analysis to evaluate the efficacy and safety of EUS-PPG. Methods: A comprehensive literature search was performed to identify pertinent studies. The primary outcomes assessed were the technical and clinical success of EUS-PPG. Technical success was defined as successful introduction of the needle into the desired vessel, while clinical success was defined as the correlation of the stage of fibrosis on the liver biopsy to EUS-PPG, or concordance of HVPG and EUS-PPG. The secondary outcomes were pooled rates for total and individual adverse events related to EUS-PPG. Pooled estimates were calculated using random-effects models with a 95% confidence interval (CI). Results: Eight cohort studies with a total of 178 patients were included in our analysis. The calculated pooled rates of technical success and clinical success were 94.6% (95%CI 88.5-97.6%; P=<0.001; I2=0) and 85.4% (95%CI 51.5-97.0%; P=0.042; I2=70), respectively. The rate of total adverse events was 10.9% (95%CI 6.5-17.7%; P=<0.001; I2=4), and 93.7% of them were mild, as defined by the American Society for Gastrointestinal Endoscopy. Abdominal pain (11%) was the most common adverse event, followed by bleeding (3.6%). There were no cases of perforation or death reported in our study. Conclusions: EUS-PPG is a safe and effective modality for diagnosing portal hypertension. Further randomized controlled trials are needed to validate our findings.

Granulomatous Hepatitis Treated With Certolizumab Pegol.

Idiopathic granulomatous hepatitis is a rare condition characterized by hepatic granulomas with constitutional symptoms such as recurrent fevers, myalgias, and hepatosplenomegaly in the absence of infection or inflammatory disorder. Typical treatment and course of this disease consist of a course of steroids with rapid symptom resolution. However, symptoms may recur when steroids are tapered. In these circumstances, azathioprine, methotrexate, infliximab, and adalimumab have demonstrated good response. In this case, we present a patient who developed antidrug antibodies to infliximab and adalimumab and was the first documented case of this disease to be treated with certolizumab pegol. Our case highlights the novel efficacy of certolizumab pegol for idiopathic granulomatous hepatitis and its role in treating idiopathic granulomatous hepatitis with antidrug antibodies.

Duodenocaval Fistula: Unmasking the Rare Culprit of Gastrointestinal Hemorrhage.

Duodenocaval fistula is an extremely rare and life-threatening cause of gastrointestinal hemorrhage and septicemia. Diagnosing this condition is challenging due to its nonspecific symptoms, leading to significant delays in diagnosis and contributing to its remarkably high mortality rate. We present a unique case of duodenocaval fistula associated with prior radiation, peptic ulcer disease, and antiangiogenic cancer therapy, nearly resulting in the death of a young patient.
