Successful endoscopic management of gastric perforation caused by ingesting a sharp chicken bone

Endoscopic management of gastric perforation secondary to chicken bone: A report of 2 cases

•

The majority of ingested foreign bodies pass through the gastrointestinal tract harmlessly.

•

Ingested foreign bodies can cause significant complications like bowel obstruction, bleeding, abscess formation, migration to other organs, and perforation.

•

In selected cases, endoscopic management is more cost-effective, minimally invasive, has less post-operative complications, and leads to a more expeditious recovery.

Introduction

Ingested foreign bodies (IFB) can uncommonly cause perforation of the gastrointestinal tract. The traditional management is surgical exploration via laparotomy or laparoscopy, although endoscopic options are now gaining prominence.

Presentation of case

We present two patients with almost identical clinical presentations of post-prandial abdominal pain and anorexia. On examination they were haemodynamically stable with localised epigastric tenderness. Both patients underwent CT scan of the abdomen, with one scan revealing a foreign body in the stomach penetrating the full thickness of the gastric wall with the tip lying extraluminally. They subsequently underwent endoscopy where a chicken bone was found perforating the wall of the stomach. This was removed via snare and endoscopic clips were used to close the site of perforation.

Discussion

The majority of ingested foreign bodies pass through the gastrointestinal tract harmlessly. However some IFBs can cause significant complications like bowel obstruction, bleeding, abscess formation, migration to other organs, and in our case perforation. The diagnosis may be delayed due to an insidious clinical presentation especially if the patient does not recall ingesting anything untoward. Our patients managed to avoid surgery by undergoing successful endoscopic therapy.

Conclusion

In selected cases, endoscopic management is more cost-effective, minimally invasive, has less post-operative complications, and leads to a more expeditious recovery. Therefore, the role of therapeutic endoscopy for gastric perforations secondary to foreign bodies should always be considered.

Gastric Perforation after Chicken Bone Ingestion

Chicken bone ingestion is a common occurrence that usually passes uneventfully through the digestive tract and rarely results in complications such as perforation, which occurs very rarely within the stomach. We report here a case of a chicken bone ingestion resulting in gastric perforation, which ultimately required surgical correction.

Transcriptome profiling of cancer tissues in Chinese patients with gastric cancer by high-throughput sequencing

Gastric cancer (GC) is the fifth most common malignancy and the third leading cause of cancer-associated mortality worldwide. Therefore, there is a requirement to identify sufficiently sensitive biomarkers for GC. Genome-wide screening of transcriptome dysregulation among cancerous and normal tissues may provide insights into the underlying molecular mechanisms of GC initiation and progression. At present, high-throughput sequencing techniques have begun to innovate biomedical studies. The RNA-seq method has become an advanced approach in medical studies; it is capable of the accurate detection of gene expression levels. The present study used RNA-seq to evaluate the transcriptional changes between tumor and matched normal samples, and these changes were confirmed by differentially expressed genes in larger samples using the results of sequencing. In total, the upregulation of 28 mRNAs and downregulation of 22 mRNAs between cancerous and normal tissue samples were identified. Subsequently, five differentially expressed genes were selected to verify in large samples and cadherin-1 (CDH1) was selected to detect protein expression levels. The results revealed that CDH1, cyclooxygenase-2 and matrix metalloproteinase genes had significantly higher expression levels, whereas the expression levels of dermatopontin and transforming growth factor β receptor 2 were decreased in GC samples. In particular, CDH1 demonstrated a 36-fold higher expression level in cancer tissues. The western blotting results also revealed high CDH1 expression levels in the validation cohorts. Furthermore, these genes are highly enriched in certain gene ontology categories, including the digestive system process, secretion and digestion. The present study provided a preliminary survey of the transcriptome of Chinese patients with GC, which may improve the detection of aberrant gene expression in GC and the understanding of the mechanisms of tumorigenesis.
