Small Bowel Cancer
Small bowel cancer is a rare type of tumor and is often diagnosed late. It has several subtypes including adenocarcinoma, neuroendocrine tumor (NET), GIST, and lymphoma; the treatment approach varies markedly depending on the type.
Overview
The fundamental step of treatment is the removal of the affected bowel segment along with its associated mesentery. In subtypes such as NET and GIST, targeted medical therapy plays an important role.
Who Is It For?
- People with unexplained abdominal pain, weight loss, or occult or overt intestinal bleeding
- Those in whom a suspicious lesion is detected on imaging or capsule endoscopy
- Individuals under long-term follow-up for Crohn's disease
- Those with an increased risk under surveillance for a genetic syndrome (FAP, Lynch)
Treatment Process
- 1
Pre-Assessment & Diagnosis
The diagnosis is confirmed and the stage of the disease clarified through a detailed history, physical examination and the necessary imaging and laboratory tests.
- 2
Planning & Preparation
An anaesthesia consultation, bleeding profile and review of any accompanying conditions are carried out; a multidisciplinary council decision is taken when needed.
- 3
Procedure / Operation
The procedure is performed with the technique most suitable for the patient (laparoscopic, robotic or open); tissue integrity and oncological principles are preserved.
- 4
Follow-up & Monitoring
Early mobilization, pain control and wound monitoring are provided; suture removal and a general assessment check-up are planned after discharge.
Recovery & Aftercare
Recovery after a limited bowel resection is relatively rapid; in extensive resections, attention is needed regarding short bowel syndrome.
Hospital Stay
3-7 days
Recovery Time
2-4 weeks
Follow-up
Day 10 and week 6
Frequently Asked Questions
Why is small bowel cancer diagnosed late?
Because the symptoms are nonspecific (abdominal pain, weight loss, anemia) and the area cannot be reached with standard endoscopy, diagnosis may be delayed. Capsule endoscopy and enteroscopy increase the chance of diagnosis.
What is a GIST, and is it cancer?
GIST is the abbreviation for gastrointestinal stromal tumors. They are divided into low, intermediate, and high risk groups; surgical resection is the mainstay, and in some cases targeted therapy (imatinib) is added.
What happens if the entire small bowel is removed?
If there is not enough small bowel, short bowel syndrome develops and long-term supportive treatment is required. For this reason, the most bowel-preserving resection possible is always preferred.
Does Crohn's disease increase the risk of cancer?
Long-standing active Crohn's disease can cause a limited increase in the risk of small bowel adenocarcinoma; regular follow-up is important.
