Insights

Internal hernias, though rare in children, can cause acute abdomen after blunt trauma. Prompt diagnosis and surgical repair are crucial to prevent bowel strangulation and ischemia, as shown in a transomental hernia case.

Area of Science:

  • Pediatric Surgery
  • Abdominal Imaging
  • Trauma Surgery

Background:

  • Internal hernias are uncommon in pediatric patients.
  • Blunt abdominal trauma can precipitate internal hernias.
  • Prompt recognition is vital due to high risk of bowel strangulation and ischemia.

Purpose of the Study:

  • To highlight the importance of considering internal hernias in pediatric patients with acute abdomen post-trauma.
  • To report a case of transomental hernia (TOH) in a young girl following blunt trauma.
  • To emphasize the diagnostic and therapeutic approach for internal hernias.

Main Methods:

  • Case report of a young female patient presenting with acute abdominal pain 3 weeks after a motor vehicle accident.
  • Computed tomography (CT) scan to evaluate for small bowel obstruction and ischemia.
  • Urgent surgical intervention and laparoscopic reduction of the transomental hernia.

Main Results:

  • CT scan revealed a closed-loop small bowel obstruction with ischemic features, suggestive of internal hernia.
  • Surgical exploration confirmed a transomental hernia containing ischemic but viable small bowel.
  • Laparoscopic reduction of the TOH was successfully performed.

Conclusions:

  • Transomental hernias can occur following blunt abdominal trauma in children.
  • CT imaging is crucial for diagnosing internal hernias presenting as small bowel obstruction.
  • Laparoscopic surgery offers a successful treatment option for transomental hernias in pediatric patients.

Esophageal Perforation-I: Introduction

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....

Esophageal Perforation-II: Clinical Manifestations and Management

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.

Inflammatory Bowel Disease V: Surgical Management

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: Introduction01:22

Appendicitis-I: Introduction

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...
