Lung cancer is the most common cancer around the world, and the leading cause of cancer-related deaths. Clinical manifestations of lung cancer may vary from non-specific respiratory symptoms to symptoms due to metastases. The most common sites of metastases are the lymph nodes, liver, adrenals, bone, and brain. Metastasis of lung cancer to stomach is very rare. Here, we present a case of squamous cell lung cancer in a 71-year male metastasing to the stomach, a very uncommon site of metastasis. Key Words: Lung cancer, Melena, Metastasis, Stomach.

Review
OBJECTIVES
The utility of nasogastric aspiration and lavage in the emergency management of patients with melena or hematochezia without hematemesis is controversial. This evidence-based emergency medicine review evaluates the following question: does nasogastric aspiration and lavage in patients with melena or hematochezia and no hematemesis differentiate an upper from lower source of gastrointestinal (GI) bleeding?
METHODS
MEDLINE, EMBASE, the Cochrane Library, and other databases were searched. Studies were selected for inclusion in the review if the authors had performed nasogastric aspiration (with or without lavage) in all patients with hematochezia or melena and performed esophagogastroduodenal endoscopy (EGD) in all patients. Studies were excluded if they enrolled patients with history of esophageal varices or included patients with hematemesis or coffee ground emesis (unless the data for patients without hematemesis or coffee ground emesis could be separated out). The outcome was identifying upper GI hemorrhage (active bleeding or high-risk lesions potentially responsible for hemorrhage) and the rate of complications associated with the nasogastric tube insertion. Quality of the included studies was assessed using standard criteria for diagnostic accuracy studies.
RESULTS
Three retrospective studies met our inclusion and exclusion criteria. The prevalence of an upper GI source for patients with melena or hematochezia without hematemesis was 32% to 74%. According to the included studies, the diagnostic performance of the nasogastric aspiration and lavage for predicting upper GI bleeding is poor. The sensitivity of this test ranged from 42% to 84%, the specificity from 54% to 91%, and negative likelihood ratios from 0.62 to 0.20. Only one study reported the rate complications associated with nasogastric aspiration and lavage (1.6%).
CONCLUSIONS
Nasogastric aspiration, with or without lavage, has a low sensitivity and poor negative likelihood ratio, which limits its utility in ruling out an upper GI source of bleeding in patients with melena or hematochezia without hematemesis.

A 50-year-old woman presented to the emergency department with several episodes of melena in the last week. The patient was not hemodynamically compromised and was conservatively managed. Urgent upper gastrointestinal endoscopy and colonoscopy showed no source of bleeding. Abdominal CT demonstrated three mural nodular lesions up to 2cm in the mid jejunum with hypervascular characteristics in arterial phase without active bleeding in venous phase. Angiography (Figure 1A) revealed three tumours with neo-angiogenesis and no active bleeding. Each lesion was stained with methylene blue and followed by embolization with coils. Exploratory laparotomy (Figure 1B) showed the three nodules marked by angiography. Intestinal resection of the affected segment was performed. Histopathological study proved the diagnosis of suspicion (Figure 2).
