Summary
Gallstone ileus is rare. This case shows a gallstone causing small bowel obstruction years after initial imaging, highlighting atypical presentations of this condition.
Area of Science:
- Gastroenterology
- Surgical Case Reports
Background:
- Gallstone ileus is an uncommon cause of intestinal obstruction.
- Rigler's triad (small bowel obstruction, pneumobilia, obstructing gallstone) is not always present.
Observation:
- A 71-year-old man presented with acute small bowel obstruction.
- Imaging revealed a gallstone in the distal small bowel, with prior imaging showing it in the jejunum 4 years earlier.
- The patient had no pneumobilia or biliary-enteric fistula.
Findings:
- Laparoscopy and enterotomy successfully removed a 4x4 cm gallstone.
- The gallstone was encased in fecal material.
- The patient recovered without complications.
Implications:
- This case highlights a rare, delayed presentation of gallstone ileus.
- It emphasizes the importance of considering gallstone ileus in small bowel obstruction, even without classic signs.
- Long-term impaction of gallstones can lead to obstruction years later.

Chronic Bowel Disorders: Introduction
389
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...

Chronic Pancreatitis I: Introduction
72
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

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.
Here are some common surgical interventions for IBD:

Appendicitis-I: Introduction
89
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

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.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
