Does endoscopic sphincterotomy reduce the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis after biliary stenting? A systematic review and meta-analysis

Endoscopic biliary sphincterotomy (ES) is often carried out prior to placement of a biliary stent apparently to reduce the risk of post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). However, the protective effect of ES prior to biliary stenting is controversial. The objective of this meta‐analysis is to compare the risk of PEP and other complications after the placement of biliary stent with or without ES in patients with biliary obstruction and bile leak.

Over-the-Scope Clip system, also called “Bear Claw,” is a novel endoscopic modality used for closure of gastrointestinal defect with high efficacy and safety. We present a patient with history of eosinophilic gastroenteritis and multiple abdominal surgeries including Billroth II gastrectomy complicated by a large chronic duodenocutaneous fistula from a Billroth II afferent limb to the abdominal wall. Bear Claw clip was used for closure of this fistula. The patient developed acute cholangitis one day after placement of the Bear Claw clip. Acute cholangitis due to papillary obstruction is a potential complication of Bear Claw placement at the dome of the duodenal stump (afferent limb) in patient with Billroth II surgery due to its close proximity to the major papilla.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) has been proven to be a safe and effective method for diagnosis and treatment of biliary and pancreatic disorders. Major complications of ERCP include pancreatitis, hemorrhage, cholangitis, and duodenal perforation. We report a third case in literature of pneumoperitoneum after ERCP due to rupture of intrahepatic bile ducts and Glisson’s capsule in a peripheral hepatic lesion. Case Report: A 50-year-old male with a history of metastatic pancreatic neuroendocrine tumor and who had a partially covered metallic stent placed in the biliary tree 1 year ago presented to the oncology clinic with fatigue, abdominal pain, and hypotension. He was planned for ERCP for possible cholangitis secondary to obstructed previously placed biliary stent. However, the duodenoscope could not be advanced to the level of the major papilla because of narrowed pylorus and severely strictured duodenal sweep. Forward-view gastroscope was then passed with careful manipulation to the severely narrowed second part of the duodenum where the previously placed metallic stent was visualized. Balloon sweeping of stenting was done. Cholangiography did not show any leak. Following the procedure, the patient underwent CT scan of the abdomen that showed pneumoperitoneum which was communicating with pneumobilia through a loculated air collection in necrotic hepatic metastasis perforating Glisson’s capsule. The patient was managed conservatively. Conclusion: In our case, pneumoperitoneum resulted from rupture of intrahepatic bile ducts and Glisson’s capsule in hepatic metastasis. This case emphasizes the need for close clinical and radiological observation of patients with hepatic masses (primary or metastatic) subjected to ERCP.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy sampling of enlarged lymph nodes is increasingly used to diagnose metastatic tumors, especially of the gastrointestinal tract and the lungs. Herein, we describe the diagnosis of metastatic renal cell carcinoma from a native kidney of a 54 year-old male patient, who had a 5-years history of renal transplant, by EUS-FNA of mediastinal and celiac lymph nodes. Histological and immunohistochemical findings confirmed the origin of metastatic tumor. EUS-FNA with proper cytological evaluation can be useful in the diagnosis of metastatic renal cell carcinoma in renal transplant patients.

Two Cases of Type Va Extrahepatic Bile Duct Duplication With Distal Klatskin Tumor Surgically Treated with Whipple Procedure and Hepaticojejunostomy

We describe the diagnostic and therapeutic challenges of a type Va extrahepatic bile duct duplication coexistent with distally located hilar cholangiocarcinoma (Klatskin tumor). We present 2 cases that were diagnosed preoperatively and treated with a modified surgical technique of a combined pylorus-preserving Whipple procedure and hepaticojejunostomy.

Cylindrical Batteries in the Stomach: Should We Wait 48 Hours for Removal?

Tariq A. Hammad; Yaseen Alastal; Muhammad Z. Bawany; Ali Nawras; Mohammad Hammad; Osama Alaradi

A 31-year-old woman presented with witnessed ingestion of multiple cylindrical batteries to deliberately self-harm 2 hours prior to admission. The patient denied any symptoms. Physical exam was normal. Abdominal series showed 7 cylindrical batteries (5 AAA and 2 AA) in the upper abdomen (Figure 1). Esophagogastroduodenoscopy (EGD) under conscious sedation revealed food remnants in the stomach. Despite extensive irrigation and suctioning only 2 batteries were visualized in the stomach and both were successfully retrieved using a Roth net. No mucosal damage was apparent. The next morning, she complained of mild abdominal pain with mild epigastric tenderness. Abdominal x-ray revealed 4 batteries in the stomach, and another in the small bowel. The patient underwent repeat EGD under general anesthesia within 12 hours of the ingestion time. Stomach exam revealed 3 batteries in the body with 3 deep ulcerations (2 in the antrum and 1 in the incisura) and multiple erosions (Figure 2). Duodenal exam showed superficial mucosal erosions, and another battery was seen beyond the ligament of Treitz.
