• This primary port often becomes the main viewing channel throughout the surgery

Critical step: Safe entry is paramount—using the telescope early ensures accurate and injury-free access.

Laparoscopic Hernia Repair

In both inguinal and ventral hernia repairs, laparoscopic telescopes enable surgeons to visualize the hernia sac, reduce protruding tissue, and place a synthetic mesh to reinforce the weakened abdominal wall. The telescopic view allows for precise dissection in the preperitoneal or transabdominal space, minimizing damage to surrounding nerves and muscles.

• TAPP (Transabdominal Preperitoneal) and TEP (Totally Extraperitoneal) repairs rely heavily on 30-degree angled scopes for optimal visualization
• Minimally invasive approach results in reduced postoperative pain and lower infection rates
• Patients typically return to light activity within 3–5 days and full work duties within 1–2 weeks

Outcome advantage: Lower recurrence rates and improved cosmetic results compared to open techniques.

Laparoscopic Fundoplication for GERD

Gastroesophageal reflux disease (GERD) can be effectively treated with laparoscopic Nissen or Toupet fundoplication. Using a 30-degree laparoscopic telescope, surgeons wrap the upper part of the stomach around the lower esophagus to strengthen the anti-reflux barrier. The angled scope provides superior visualization behind the esophagus, which is critical for a secure and tension-free wrap.

• 30-degree telescopes allow multi-angle views without repositioning trocars, improving surgical efficiency
• High-resolution imaging helps identify the crura of the diaphragm and vagus nerves, preventing complications
