RESUMEN
Patients with unresectable pancreatic cancer often present with duodenal bleeding, a potentially life-threatening complication. In our case series of six unresectable pancreatic cancer patients with tumor bleeding, we explored the efficacy and safety of placement of a covered self-expandable metallic stent in the duodenum as a treatment option; we achieved a hemostasis rate of 67% (4/6), with a rebleeding rate of 50% (2/4). No complications occurred with stent placement, except for food impaction in one patient. Covered self-expandable metallic stent placement is a moderately effective treatment option for tumor bleeding in patients with unresectable pancreatic cancer. Although its hemostatic efficacy is limited, covered self-expandable metallic stent placement is safe and beneficial in some cases, warranting consideration in this disease setting with limited treatment options.
RESUMEN
RATIONALE: There is currently no consensus on the ideal method for obtaining deep tissue biopsy material of advanced gastric LP. EUS-FNA has potential as a useful diagnostic method. Thus, we report the case of a 46-year-old male with advanced gastric linitis plastica (LP) who was diagnosed using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). PATIENT CONCERNS: The patient underwent esophagogastroduodenoscopy (EGD) because of epigastric pain at a local clinic. The gastric fold swelling was pointed out by the EGD and despite the suspected advanced gastric LP, biopsy indicated Group 1. Repeat biopsy did not suggest malignancy. The patient was referred to our institution. DIAGNOSES: Endoscopic ultrasound indicated gastric wall thickening mainly in the greater curvature of the gastric corpus. Low-level echoes were detected throughout the entire gastric wall, and gastric wall layers had been disappeared. EUS-FNA of the gastric wall indicated signet ring cell carcinoma. INTERVENTIONS: As a result of EUS - FNA, it became a policy to administer chemotherapy. In accordance with the patient's wishes, he was referred to another institution for chemotherapy. OUTCOMES: Normal biopsy did not give a definitive pathological diagnosis, and final diagnosis of LP was obtained with EUS-FNA. LESSONS: We expect that EUS-FNA can be utilized as a relatively non-invasive, highly sensitive, and specific pathological diagnostic procedure for advanced gastric LP. EUS-FNA should be considered as one way to obtain a deep tissue biopsy of advanced gastric LP.
