Procedure Overview

Dr Cederwall’s private practice focuses on gastrointestinal endoscopy, motility assessment and the investigation of reflux, gastroparesis, small intestinal bacterial overgrowth and irritable bowel disease. Information here is intended to support discussions with your GP and assist with referral planning.

Gastroscopy

A gastroscopy uses a thin flexible camera to examine the oesophagus, stomach and upper small bowel. It is commonly performed for symptoms such as reflux, upper abdominal discomfort, difficulty swallowing and unexplained anaemia. Biopsies can be taken during the procedure when required.

Colonoscopy and Polypectomy

A colonoscopy allows detailed assessment of the large bowel and is used to investigate bleeding, altered bowel habits, screening needs or a family history of bowel disease. Polyps can be safely removed during the procedure, reducing the need for further visits and supporting long term bowel health.

Oesophageal Manometry

Oesophageal manometry measures pressures and muscle activity within the oesophagus. It is used to assess swallowing difficulties, reflux symptoms and suspected motility disorders. The results help clarify how the oesophagus is functioning and guide further management.

Twenty Four Hour pH Impedance Testing

This test records both acid and non-acid reflux over a full day using a fine catheter placed in the oesophagus. It is used to determine whether symptoms are related to reflux episodes and is particularly helpful when symptoms persist despite standard treatment.

Wireless pH Monitoring (Bravo)

The Bravo system provides extended acid-exposure monitoring without a nasal catheter. A small capsule is placed during gastroscopy and records pH levels for 96 hours. It offers a well-tolerated and accurate assessment of reflux disease in a natural daily environment.

Carbohydrate Breath Testing

Breath testing assesses how certain carbohydrates are digested and absorbed. It can help identify lactose intolerance, fructose malabsorption or small intestinal bacterial overgrowth. It is a non-invasive test often used to investigate bloating, discomfort and variable bowel habits.

Gastric Electrical Mapping (Alimetry)

Alimetry is a non-invasive test that records the electrical activity of the stomach through sensors applied to the skin. It provides information about gastric rhythm and motility and is used to assess symptoms such as nausea, early fullness and chronic upper abdominal discomfort.
