The next generation of minimally invasive instruments for pyloromyotomy

Children with infantile hypertrophic pyloric stenosis (IHPS) are born with an enlargement and thickening of the circular pyloric muscle (muscle controlling the exit of food from the stomach). This means that the passage leading out of the stomach is constricted by the enlarged muscle and food is unable to pass out of the stomach. Infants therefore regularly regurgitate their meals and this leads to a dangerous imbalance in metabolism and dehydration.
A pyloromyotomy is therefore carried out to expand the pylorus using a minimally invasive surgical technique.

The SAXENA Pyloric Spreader offers:

• Sheath diameter 3.5 mm
• In working lengths 240 mm and 330 mm
• Modular, three-part structure
• Ergonomic pyloric spreader jaw specially designed for IHPS
• Flat instrument tip for simple positioning of the pyloric spreader in the incision of the pyloric muscle
• Atraumatic, finely rounded tip minimizes injuries to the mucosal membrane
• Wide contact areas of the jaw guarantee uniform dilation of the muscle
• The joint mechanism at the distal end is entirely covered by the sheath and this excludes tissue from being inadvertently trapped in the projecting joint mechanism
• A selection of different handles can be combined
• New generation for more efficiency in IHPS
• Sets safety standards for IHPS interventions

This special instrument was developed in cooperation with Professor Amulya Kumar Saxena, Chelsea and Westminster Hospital NHS Foundation Trust and Imperial College, London.
