Summary
Primary small bowel cancers are often diagnosed late, typically presenting as emergencies like obstruction or perforation. Surgical treatment in these urgent cases leads to considerable morbidity and mortality.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Epidemiology
Background:
- Small bowel cancers are rare but serious malignancies.
- Understanding their epidemiological patterns is crucial for early diagnosis and management.
Purpose of the Study:
- To characterize the demographic, clinical, and pathological patterns of primary small bowel cancers.
- To analyze the common presentations and complications of these tumors in an East-European tertiary hospital.
Main Methods:
- Retrospective analysis of 57 patients diagnosed with small bowel cancer over 15 years.
- Data collection included patient demographics, admission reasons, tumor location, and histological type.
Main Results:
- Most patients (84.2%) presented as emergencies, primarily due to obstruction (38.9%) or perforation (31.5%).
- Gastrointestinal stromal tumors (42.1%) and adenocarcinoma (33.3%) were the most frequent types.
- Duodenal tumors showed a higher prevalence than expected for their location.
Conclusions:
- Primary small bowel cancers are frequently diagnosed at advanced stages, often revealed by complications.
- Emergency surgical management of these cancers is associated with high rates of morbidity and mortality.

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
