Insights

Hiatal and paraesophageal hernia (HH/PEH) can arise congenitally or be acquired after surgery. Minimizing esophageal dissection during Nissen fundoplication significantly reduces the risk of acquired HH/PEH.

Area of Science:

  • Gastroenterology and Surgical Science

Background:

  • Hiatal and paraesophageal hernia (HH/PEH) are conditions that can be congenital or acquired, often following gastroesophageal surgery like fundoplication.
  • Acquired HH/PEH is frequently linked to surgical procedures, with significant rates reported after Nissen fundoplication.

Purpose of the Study:

  • To investigate the incidence of acquired hiatal and paraesophageal hernia (HH/PEH) after Nissen fundoplication.
  • To evaluate the impact of surgical technique, specifically minimizing circumferential esophageal dissection, on the occurrence of acquired HH/PEH.

Main Methods:

  • Analysis of patient data following Nissen fundoplication surgery.
  • Comparison of HH/PEH rates between standard and modified surgical techniques (minimizing esophageal dissection).

Main Results:

  • The risk of acquired HH/PEH decreased from 36.5% to 12.2% when circumferential esophageal dissection was minimized during Nissen fundoplication.
  • Gastrointestinal, respiratory, and constitutional symptoms, including anemia and failure to thrive, are common in patients with HH/PEH, often associated with gastroesophageal reflux.

Conclusions:

  • Minimizing circumferential esophageal dissection during Nissen fundoplication is a crucial technical modification to reduce the incidence of acquired HH/PEH.
  • Surgical correction of HH/PEH involves hernia reduction, sac excision, crural closure, and an antireflux procedure, with laparoscopy being a safe and effective approach.

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.

Esophageal Perforation-I: Introduction01:22

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....

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
