General & Upper Gastrointestinal Surgery

 

Specialist surgical care for common and complex GI conditions

In addition to weight management and bariatric surgery, Dr Jess Mok provides private consultation and surgical treatment for a wide range of general and upper gastrointestinal conditions.

Her practice is grounded in minimally invasive (keyhole) surgery, evidence-based decision-making, and personalised care.

Gastrointestinal symptoms Dr Jess Mok can help with

 

Many patients experience persistent or recurrent digestive symptoms without a clear diagnosis. These symptoms can significantly affect quality of life and are often under-investigated or poorly explained.

Dr Jess Mok provides specialist assessment for a wide range of upper gastrointestinal and digestive symptoms, offering clear explanations, appropriate investigations, and personalised treatment plans.

  • Dr Mok regularly assesses patients with symptoms including:

    • Bloating or abdominal distension

    • Heartburn or acid reflux

    • Upper abdominal pain or discomfort

    • Pain or nausea after eating

    • Early fullness or reduced appetite

    • Indigestion or dyspepsia

    • Swallowing difficulties

    • Unexplained gastrointestinal symptoms

    Patients do not need to have a diagnosis before seeking consultation.

  • Dr Mok takes a careful, structured approach to understanding symptoms, including:

    • Detailed clinical history and examination

    • Review of dietary patterns and symptom triggers

    • Consideration of functional and structural causes

    • Arrangement of appropriate investigations where indicated

    When required, upper gastrointestinal endoscopy (gastroscopy) can be performed to assess the oesophagus, stomach, and duodenum and help exclude or diagnose underlying conditions.

    Dr Mok is a high-volume and experienced endoscopist, with a particular interest in using endoscopy appropriately and thoughtfully as part of a wider clinical assessment.

  • Dr Mok recognises that gastrointestinal symptoms are often multifactorial and that effective care requires time, listening, and individualised planning.

    Patients are supported with:

    • Clear explanations

    • Evidence-based investigation

    • Thoughtful use of procedures

    • A focus on long-term symptom control and quality of life

 Gallbladder conditions

Gallbladder problems are common and can cause significant pain and disruption to daily life.

Conditions treated include:

  • Gallstones

  • Biliary colic

  • Gallbladder polyps

  • Acute or chronic cholecystitis

  • Gallstone-related complications

Laparoscopic (keyhole) cholecystectomy is offered when appropriate.

Acid reflux & upper GI conditions

Persistent reflux symptoms should not be ignored.

Assessment and treatment are offered for:

  • Gastro-oesophageal reflux disease (GORD)

  • Hiatus hernia

  • Upper abdominal pain and swallowing difficulties

Where appropriate, surgical options for reflux may be discussed following thorough investigation.

Hernias

Hernias can cause discomfort, pain, or complications if left untreated.

Dr Jess Mok assesses and treats:

  • Inguinal hernias

  • Umbilical and paraumbilical hernias

  • Incisional hernias

  • Epigastric hernias

Treatment options include minimally invasive repair, with or without mesh, and abdominal wall reconstruction techniques

Lumps and bumps (minor surgery)

Lumps and bumps under the skin are common and can cause discomfort, concern, or cosmetic distress. While many are benign, assessment by a specialist can provide reassurance and help determine whether treatment is required.

Conditions treated include:

  • Lipomas (benign fatty lumps)

  • Sebaceous and epidermoid cysts

  • Skin tags

  • Other benign soft-tissue lumps

Where appropriate, surgical excision can be performed under local anaesthetic

Surgical approach

Dr Mok specialises in:

  • Minimally invasive (laparoscopic) surgery

  • Careful patient selection

  • Clear explanation of risks, benefits, and alternatives

Not all conditions require surgery, and conservative management is discussed where appropriate.

What to expect from a consultation

During a general or upper GI consultation:

  • Symptoms and medical history are reviewed

  • Relevant investigations are discussed or arranged

  • Treatment options are explained clearly

  • A personalised plan is agreed

There is no obligation to proceed with surgery following consultation.
