General rules for GIT bleeding
2-5 ml normal blood loss
10-50 ml FOB ‘foecal occult blood’ in screening of colorectal cancer
50-100 ml  Enough to produce melena
1000 ml From upper GIT produce haematochesia
1000 ml In a day produce melena for 3-5 days, melena poor indicator of recent bleeding
The character (color) of blood passed from GIT depend upon:

  • Time expense in GIT
  • Site
Lower GIT bleeding by definition originate below Treitz ligament at D-J junction
Upper GIT bleeding by definition originate above Treitz ligament at D-J junction
Melena is bleeding above ilio-ceacal valve (digested blood)
So presence of melena indicate

  • Bleeding >100 ml
  • presence of melena for 3-5 days indicate
  • bleeding of 1000 ml

  • Intestinal fistula

  • Acquired
  • Umbilical granuloma

Clinical Surgery Notes for MRCS OSCE part B exam for DOWNLOAD

Very Important

It is not the intention of these note to be a complete comprehensive notes for the clinical examination in General Surgery or for the OSCE part B MRCS examination.

The main intention of these notes is to create a skeleton upon which you can build up your plans in clinical examination. In addition to that, it can be used for a quick revision before the exam.

You can NOT go for the exam without keeping these notes by heart.

But also, you can NOT got for the exam with these notes alone.

Please refer to clinical examination textbooks like

  • “Browse’s Introduction to the Symptoms & Signs of Surgical Disease, Fifth Edition by Kevin G. Burnand (Editor), John Black (Editor), Steven A. Corbett (Editor),”
  • “Clinical Cases and OSCEs in Surgery (MRCS Study Guides)” by Manoj Ramachandran (Author), Marc A Gladman (Author)

Note that, you have to practice each examination as much as you can on real patients, volunteers or even your colleagues.

These notes cover 6 out of 18 stations of the MRCS OSCE part B exam.


Your feedback are highly recommended and appreciated.

Skin lesions of Surgical importance

Terms (of surgical importance) used to describe skin pathology
Macule Localized change in color of the skin

Not elevated (or palpable) or freckled

Papule Small solid elevation

Flat toped, conical, rounded, polyhedral, follicular (hairs), smooth or scaly

Vesicle Small collection of fluid

Between the dermis and epidermis (a blister)

Bulla Collection of fluid larger than a vesicle

Under epidermis

Wheal Transient elevation of the skin caused by edema
Cyst Tumor that contains fluid
Naevus Lesion present from birth

Composed of mature structures normally found in the skin but present in excess or an abnormal disposition

Also used to describe lesions composed of naevus cells as melanocytic or pigmented naevi

Papilloma Benign overgrowth of epithelial tissue
Tumor Literally, a swelling

Commonly but inaccurately used to mean an malignant swelling

Hamartoma Overgrowth of one or more cell types that are normal constituents of the organ in which they arise

The commonest examples




Ulcer Area of solution of an epithelial surface
