Jason Diab is a General Surgeon based in Sydney, NSW, Australia.
He works with people of all ages, from kids to adults, and he helps manage both planned and urgent problems. In many cases, that means assessing symptoms carefully, talking through options, and then doing the right operation when surgery is needed.
On the adult side, Jason regularly looks after conditions like hernias and abdominal emergencies such as appendicitis, bowel perforation, and other serious gut issues. He also treats problems involving the gallbladder and other parts of the digestive system, and he may use endoscopy as part of the care plan when appropriate. Over time, he also sees people with colorectal cancer and other complex bowel conditions, working with the wider hospital team to support treatment and recovery.
For children, Jason’s surgical work includes head shape and skull growth issues like craniosynostosis, metopic ridge, lambdoid synostosis, and plagiocephaly. He also helps with childhood conditions such as childhood volvulus. These cases can be stressful for families, so clear communication matters, especially when timing and ongoing follow-up are part of the story.
Jason also deals with infections and other urgent conditions, including necrotizing fasciitis and deep infections such as breast infection. He has experience with hydrocele and other non-emergency surgical issues too. Sometimes patients come in with difficult symptoms, and he focuses on making sure nothing important is missed.
He also treats a range of rarer conditions, including adrenal cancer and anaplastic large cell lymphoma (ALCL). And at times he manages situations linked to the median arcuate ligament syndrome (MALS). There are many different paths for different diagnoses, so Jason’s approach is practical and step-by-step.
