Biliary stent migration presenting as transdiverticular sigmoid perforation
Journal of Surgical Case Reports
|June 21, 2014
Summary
A rare complication of biliary stent placement occurred when a stent migrated and perforated the sigmoid colon. This case highlights the need to consider stent migration in patients with abdominal pain after the procedure.
Area of Science:
- Gastroenterology
- Surgical Complications
Background:
- Biliary stent placement is a common procedure for managing biliary obstructions.
- Complications, though infrequent, can arise from indwelling biliary stents.
Purpose of the Study:
- To report a rare case of distal biliary stent migration causing sigmoid diverticulum perforation.
- To emphasize the importance of considering this complication in the differential diagnosis.
Main Methods:
- A case report detailing a patient's presentation and management.
- Review of the clinical course following endoscopic retrograde cholangiopancreatography (ERCP) with stent placement.
Main Results:
- Distal migration of a plastic biliary stent led to perforation of a sigmoid diverticulum.
- The perforation was successfully managed with sigmoid resection and primary anastomosis, with the ileum containing the perforation.
Conclusions:
- Sigmoid diverticulum perforation due to biliary stent migration is a rare but significant complication.
- Clinicians should include this possibility in the differential diagnosis for lower abdominal pain post-ERCP with stent placement.

1.1K
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:19Appendicitis
28
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

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...

01:22Esophageal Perforation-I: Introduction
841
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

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...

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
