Irritable Bowel Disease awareness


Know the signals and the symptoms to irritable bowel syndrome – a common disorder that affects 30% of adults

IBS – the facts

This very common gastrointestinal disorder affects up to 30% of the adult population.
Classical symptoms are of cramping abdominal
pain, abdominal bloating, alteration in bowel
habit, either diarrhoea or constipation,
mucus discharge, incomplete evacuation of
faeces and gastroesophageal reflux disease
(GORD). The persistence of these symptoms,
or the passage of blood through the rectum,
should initiate a referral to your GP.

IBS is assumed to be associated with abhorrent signals
between the brain and the gut. It can also be
triggered by a severe infective episode of
gastroenteritis, or it can even be stress related.

Managing the condition

Investigation after concise history taking and
examination can often be managed on an
outpatient basis, following basic blood tests
(thyroid function test, coeliac screen) and stool
tests. 

In the presence of persisting symptoms such as constant diarrhoea
or rectal bleeding, colonoscopy may be required, especially when
over the age of 35, to exclude an alternative cause for the symptoms.
Management often involves certain dietary
modifications, for example, the low FODMAPS
diet has gained increasing acceptance recently
for improving symptom control. 
Refractory IBS can often be managed with good symptomatic
outcomes through avoidance of precipitating
factors, various relaxation techniques and bowel
retraining techniques.

Risk factors for colorectal cancer


Concerns regarding colorectal cancer remain a topical issue, primarily because of its common nature with over 30, 000 new cases being diagnosed on an annual basis in the UK alone.

It is the third most common cancer in the UK. In addition, there has been increased exposure to the disease, since the government introduced the national screening programme, in an effort to reduce the significant implications associated with the diagnosis of advanced disease.




So what are the risk factors ?

Age. Colorectal cancer is a disease that primarily affects people over the age of 50. It can however occur at a younger age, but is less common. Despite this in a symptomatic individual (see below) irrespective of age, but especially over the age of 35, there is a low threshold to investigate.

Family history of colorectal cancer (CRC) or high risk colon polyps.

Patients with a family history of either of the above have an increased risk of developing the disease and thus require further investigation. The presence of a first degree relative who has developed CRC under the age of 60 (in particular under the age of 45) or alternatively has a family history of multiple cancers should be referred for early colonoscopy and genetic surveillance.

Previous surgery for colorectal cancer

Will require long term surveillance.

Chronic inflammatory conditions of the colon

Ulcerative Colitis and Crohns disease increase the risk of developing colorectal cancer.

Diabetes & Obesity

Patients with diabetes or who are obese have an increased risk of colorectal cancer.

Diet

There is a weak association between eating large amounts of red meat and colorectal cancer.

Smoking and Alcohol

Excessive consumption of either is associated with an increased risk of colorectal cancer.

What measures are undertaken in the clinical setting?

New onset symptoms are actively pursued during consultation, in all age groups, primarily to exclude alternative diagnoses. It is important to maintain a high index of clinical suspicion, with increasing age.

High risk symptoms

                Rectal bleeding with altered bowel habit (loose stools for more than 6 weeks)
                Rectal bleeding in the absence of anal canal symptoms eg itching
                Increased frequency of bowel movements for more than 6 weeks
                Palpable abdominal mass or rectal mass
                Iron deficiency anaemia

Low risk symptoms

                Transient change in bowel habit, less than 6 weeks (e.g constipation)
                Persisting abdominal discomfort, (age more than 50, there is a 10% association with intra abdominal malignancy)
                Impaired Glucose tolerance (type II diabetes).

The patient pathway

Having undertaken a concise history and following a thorough examination, a rigid sigmoidoscopy is undertaken in clinic.

Thereafter flexible sigmoidoscopy, colonoscopy or alternatively CT pneumocolon will be undertaken on an elective basis to establish an aetiology for the symptoms described.

If further intervention is indicated, the use of minimally invasive techniques such as keyhole surgery enhances recovery, enabling a more rapid return to normal activity, with minimal lifestyle disruption.

Haemorrhoids: What are they?

Haemorrhoids: What are they?

Haemorrhoids (or piles, which is their alternative name) 
are vascular cushions (lined by blood vessels), which are very 
common. It is quoted that over 50% of adults over the 
age of 50 have haemorrhoids and experience symptoms 
compatible with haemorrhoids. However, they can occur 
at any age. They have a role in the maintenance of continence 
(the prevention of accidents from the back passage and the 
inappropriate passage of wind, liquid or solid stools).


What causes them?

Prolonged straining when going to the toilet, often associated with constipation and sitting on the 
toilet for long periods of time are thought to be associated with the development of haemorrhoids. 
The theory is that the perineal muscles (pelvic floor) remain unsupported during protracted straining 
on the loo.

How do they present?

There are a wide variety of symptoms, but namely, bleeding and discomfort from the back passage, 
both of which may be associated with other benign conditions (such as anal fissure), 
itching (pruritus ani) or a small lump at the anal verge. If bleeding is identified then it is imperative,
that other sinister conditions should be excluded through 
colonoscopy (telescope test of the back passage) or a CT pneumocolon (in the appropriate age group).

Management

In the majority of cases, haemorrhoids can be managed entirely conservatively 
(i.e. do nothing and adopt a watch and wait policy). The most important aspect, is to exclude an 
alternative cause for the symptoms, especially in the presence of rectal bleeding or other symptoms 
such as ongoing constipation or diarrhoea. The conservative options available in the 
outpatient setting include dietary advice (eating a diet high in natural fibre), 
The latter are associated with very low risks e.g. recurrent bleeding or post procedure discomfort, 
more so with banding.

Surgery

For patients with refractory symptoms, i.e. persistent symptoms that have not been improved by 
the conservative measures described and where symptoms affect quality of life, the options 
available are either conventional haemorrhoidectomy, which in the past has had bad press, 
in view of the perceived complications, namely post operative pain. However, this is less so now.

Techniques such as stapled haemorrhoidectomy have been practised for over 10 years and is 
particularly good for symptoms of haemorrhoidal prolapse. More recently, 
the haemorrhoidal artery ligation technique (HALO) has been increasingly used as a technique with 
encouraging results and less post operative discomfort.

The complications associated with surgery are low, but include post operative pain, recurrent bleeding 
and to a lesser degree narrowing of the anus (stenosis).

Summary

Haemorrhoids are extremely common. The most important concept regarding their management 
is to exclude alternative pathology, especially in the presence of rectal bleeding, through ideally 
colonoscopy. This is to exclude any sinister lesion which can masquerade with identical symptoms
The large majority of patients can be managed entirely conservatively, without recourse to surgery. 
However, should symptoms prove to be problematic and impact on life style, then surgery is the 
best long term option, assuming that the other conservative options described have been exhausted 
prior to this.
