Summary
A rare small intestine leiomyosarcoma caused intussusception in an elderly man. Early laparoscopic surgery offered a curative outcome, highlighting its effectiveness for this aggressive gastrointestinal tumor.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Small intestine leiomyosarcoma is a rare gastrointestinal malignancy.
- Intussusception can be a presenting symptom of small intestinal tumors.
- Leiomyosarcoma diagnosis is often confirmed via immunostaining.
Purpose of the Study:
- To report a case of small intestine leiomyosarcoma presenting as intussusception.
- To discuss the diagnostic and therapeutic challenges of this rare tumor.
- To evaluate the efficacy of minimally invasive surgical resection.
Main Methods:
- Diagnosis of small intestine intussusception using computed tomography (CT).
- Laparoscopic-assisted partial small intestine resection.
- Pathological examination and immunostaining for leiomyosarcoma confirmation.
Main Results:
- A curative laparoscopic resection was performed on an 87-year-old man with small intestine leiomyosarcoma.
- This represents one of 15 confirmed cases in Japan since 1999.
- The disease has a poor prognosis, with 5 of 15 cases resulting in death within 17 months.
Conclusions:
- Early local resection via laparoscopy is an effective treatment for neoplastic small bowel intussusception.
- Minimally invasive surgery can achieve curative outcomes for small intestine leiomyosarcoma.
- Prompt surgical intervention is crucial given the poor prognosis of this rare malignancy.

01:23Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

01:29Intestinal Obstruction I: Introduction
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
