Adenocarcinoma of the Jejunum: Management of a Rare Tumor of the Small Intestine

Abstract: Small bowel adenocarcinoma constitutes an uncommon malignancy, accounting for less than 2% of all gastrointestinal cancers. Its clinical manifestations are usually vague and non-specific, often presenting as abdominal pain, vomiting, gastrointestinal bleeding, or intestinal obstruction. Because of this lack of specific symptoms, diagnosis is frequently delayed, which adversely affects the prognosis. We describe the case of a 50-year-old male diagnosed with jejunal adenocarcinoma who initially presented with chronic abdominal pain and intermittent episodes of vomiting. The diagnosis was confirmed three months after symptom onset. The patient subsequently underwent an exploratory laparotomy with segmental resection of the jejunum, primary end-to-end anastomosis, and regional lymphadenectomy. The postoperative course was uneventful.
