Aim of this module

This module will provide trainees with the opportunity to gain advanced knowledge of Upper Gastrointestinal physiology.

Direct Observation of Practical Skills Titles

  • Perform adjunctive tests with esophageal manometry, using current guidelines.
  • Insert, remove and adjust any event markers on a pH-impedance study.
  • Review symptom association with reflux for a pH-impedance study.

Observed Communication Event Titles

  • Explain complex upper gastrointestinal physiology procedures to patients.
  • Explain the procedure and provide support to a patient during HRM adjunctive testing.
  • Discuss a complex oesophageal manometry investigation with a colleague.
  • Discuss the patient’s medication regime with the patient, identifying medications that may interfere with the outcome of upper gastrointestinal physiology investigations and advise accordingly.

Learning outcomes

# Learning outcome
1

Perform high-resolution oesophageal manometry in the complex patient, including a full range of adjunctive tests as appropriate.

2

Perform combined oesophageal pH-impedance monitoring in adult patients presenting with a wide range of conditions.

3

Analyse and interpret the data producing complete reports for both high-resolution oesophageal manometry and oesophageal pH-impedance monitoring, making recommendations for subsequent management/treatment.

4

Analyse and interpret the data producing preliminary reports from high-resolution manometry (HRM), differentiating between artefact and physiological occurrences.

5

Practice professionally within the multidisciplinary team.

6

Employ effective communication skills to present information to a variety of audiences including patients, carers and healthcare professional colleagues.

7

Interpret manometric patterns in the proximal oesophagus/crycopharynx and identify abnormalities, using knowledge from the wider multidisciplinary team.

8

Identify situations where physiological measurements are affected by pharmacological interactions and the impact this may have on test results.

Clinical experiences

Clinical experiences help you to develop insight into your practice and a greater understanding of your specialty's impact on patient care. Clinical experiences should be included in your training plan and you may be asked to help organise your experiences. Reflections and observations from your experiences may help you to advance your practice and can be used to develop evidence to demonstrate your awareness and appreciation of your specialty.

Activities

  1. Observe upper gastrointestinal endoscopy and barium swallow to appreciate the anatomy and physiology and role of the investigation in the patient pathway.
  2. Observe upper gastrointestinal surgery e.g., anti-reflux surgery or laparoscopic myotomy.
  3. Observe endoscopic therapy e.g., Botox, dilatations or POEM.
  4. Attend dietetics or enteral feeding clinics or services.
  5. Attend ENT clinics including transnasal endoscopy, UOS dilatation and respiratory to observe management of patients with atypical symptoms of reflux.
  6. Attend nuclear medicine clinics to observe how they feature in the patient pathway e.g., gastric emptying SeHCAT.
  7. Attend conservative treatment clinics e.g., CBT, diaphragmatic breathing, psychotherapy and hypnotherapy.
  8. Attend a video fluoroscopy or speech and language therapy (SALT) clinic.

Academic content (MSc in Clinical Science)

Important information

The academic parts of this module will be detailed and communicated to you by your university. Please contact them if you have questions regarding this module and its assessments. The module titles in your MSc may not be exactly identical to the work-based modules shown in the e-portfolio. Your modules will be aligned, however, to ensure that your academic and work-based learning are complimentary.

Learning outcomes

On successful completion of this module the trainee will be able to:

  1. Differentiate between benign upper gastrointestinal system conditions and critically appraise the range of investigations available.
  2. Critically evaluate the range of technologies and techniques used to investigate benign upper gastrointestinal system disease in complex patients and the role of additional investigations.
  3. Critically evaluate factors that influence confidence in investigation techniques including spectrums of normality and device error ranges, in addition to physiological artefact.
  4. Classify drugs used to treat upper gastrointestinal system disorders and differentiate the actions of these agents from other drugs that might confound diagnosis.
  5. Critically evaluate risk, safe working practices, quality assurance and infection control in the context of the investigation of complex benign upper gastrointestinal system disorders.
