Advanced Upper Gastrointestinal (GI) Surgery

Advanced Upper Gastrointestinal (GI) surgery covers operations on the oesophagus, stomach, and the upper part of the small intestine. Mr Osama Moussa specialises in benign (non-cancer) conditions of this area, using both laparoscopic (keyhole) and robotic techniques to deliver precise, minimally invasive care.

Conditions treated include acid reflux (GORD), hiatus hernias, achalasia, gallbladder disease, and hernias affecting the upper abdomen. Each treatment plan is tailored to the individual, with the aim of relieving symptoms, restoring function, and improving quality of life.

Mr Moussa is trained in both Versius and Intuitive robotic platforms and has extensive experience in laparoscopic Upper GI surgery. He works at West Hertfordshire NHS Trust and at Spire Bushey and Circle Health Group hospitals, offering care across London and Hertfordshire.

His practice is focused on patient-centred outcomes: shorter hospital stays, faster recovery, and lower risk of complications where minimally invasive surgery is appropriate. He is happy to discuss the best approach for your condition and to answer any questions before you decide on treatment.

After referral, you will have a consultation to discuss your symptoms, any previous tests, and the options available. If surgery is recommended, the procedure, benefits, and risks will be explained in detail. Follow-up and aftercare are arranged so you are supported throughout your recovery.
