Enquiries & Appointments



All necessary procedures are explained in full (with explanatory leaflets), including any preparation required, at the initial outpatient consultation. A consent form is signed on the day of the procedure, and a copy is provided for reading beforehand. The patient is supplied with a copy of the report (with photographs) following the endoscopy, along with a full explanation of the results. A further outpatient consultation is usually then arranged, to allow full discussion of any results and pathology specimens taken, and any further treatment required. Both the Clementine Churchill and Cromwell hospitals have fully equipped endoscopy units

Procedures performed by Dr Sherman personally include :

  • Rigid sigmoidoscopy / proctoscopy
  • Gastroscopy (including a full range of therapeutic procedures under X Ray control)
  • Flexible Sigmoidoscopy
  • Colonoscopy and polypectomy
  • ERCP (including management of gallstones and obstructive jaundice)
  • Percutaneous Gastrostomy and Jejunostomy Insertion
  • Enteroscopy

Dr Sherman undergoes regular annual NHS appraisal, which included evaluation of his endoscopic practice. This shows high procedure completion rates (95-98% for colonoscopy, 86-90% for ERCP) and low rates of complications.
