Surgery for primary small bowel tumors is challenging, with lymphoma and adenocarcinoma being most common. Survival rates vary by tumor type, highlighting the need for timely diagnosis and treatment.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Oncology

Background:

  • Primary malignant tumors of the small bowel are rare but serious conditions.
  • Diagnosis is often delayed due to non-specific symptoms.

Purpose of the Study:

  • To analyze the clinical characteristics, surgical management, and outcomes of patients with primary malignant small bowel tumors.
  • To identify prognostic factors influencing survival.

Main Methods:

  • Retrospective review of 69 patients who underwent surgery for primary malignant small bowel tumors over 15 years.
  • Exclusion of periampullary lesions and other known adenocarcinomas.
  • Analysis of patient demographics, symptoms, physical findings, diagnostic methods, tumor types, locations, surgical procedures, and survival data.

Main Results:

  • Lymphoma (42%) and adenocarcinoma (38%) were the most frequent types. Jejunum was the most common site (41%).
  • Abdominal pain was the most frequent symptom (83%). 43% of symptomatic patients presented as surgical emergencies.
  • The 5-year overall survival was 43.25%, with higher survival for carcinoid tumors (60%) compared to lymphoma (40%) and adenocarcinoma (34.28%). Operative mortality was 10% and morbidity was 24%.

Conclusions:

  • Primary small bowel tumors present with diverse clinical features, often leading to delayed diagnosis.
  • Surgical resection is crucial, with curative intent in 61% of cases.
  • Tumor type significantly impacts prognosis, necessitating tailored treatment strategies.
