Small bowel adenocarcinoma: Case reports and review of the literature

Jejunal adenocarcinoma; a case report and literature review

INTRODUCTION AND IMPORTANCE

Small bowel carcinoma (SBC) is a rare malignancy comprising mainly of adenocarcinoma and carcinoid tumors. Among SBCs, small bowel adenocarcinoma (SBA) accounts for 30-40 % and is predominantly found in the duodenum, while jejunal and ileal presence considered rare.

CASE PRESENTATION

We have presented a case of jejunal adenocarcinoma in a patient with obstruction symptoms. Prior to the obstruction, the patient mainly suffered from weakness and weight loss, in addition to iron deficiency anemia. During the investigation of underlying causes, we observed evidence of mass. However, before any additional evaluation could take place, the obstruction necessitated surgical intervention.

CLINICAL DISCUSSION

Small bowel adenocarcinomas, particularly in the jejunum and ileum, are exceedingly rare and often present with complications such as obstruction, gastrointestinal bleeding, or perforation. Due to the non-specific symptoms, SBAs are challenging to diagnose before complications occur. SBAs are frequently diagnosed at advanced stages, so early diagnosis is crucial, as it can significantly impact patient survival. Thus, efforts should be made to expedite the diagnosis process to avoid complications and improve survival rates.

CONCLUSION

SBAs are a rare condition, often diagnosed by related complications. Recognizing the importance of early diagnosis and its positive influence on patient survival, physicians and surgeons should consider SBA in patients presenting with relevant symptoms or cases of obstruction.
