The liver is the engine of the human body. It is basically composed of 2 types of cells (a cell is the basic building block of the human body)   hepatocytes (liver cells) and cholangiocytes (bile duct cells). It also has other supporting tissue and their respective cells. The hepatocytes are by far the most numerous cell type, not surprisingly tumours (otherwise called mass or lump.  Tumor  means lump in Latin), of this cell form the majority of abnormal growths in the liver. Abnormal growths can be benign (that is, they do not grow rapidly, spread to other parts of the organ or to other parts of the body) or malignant (grow rapidly, spread to other parts of the organ and to other parts of the body, i.e. cancer). These abnormal growths from liver cells are Focal nodular hyperplasia (FNH), Adenomas (the benign variety) and hepatocellular cancer (otherwise called Hepatoma/HCC, the cancerous type). What we need to recognize is that certain adenomas can turn into HCC, over a period of time. The other type of growths in the liver are those that have originated elsewhere in the body and spread to the liver, for example a growth of the breast spreading to the liver. These are in fact the commonest tumours of the liver. I will discuss these at a later date.

Benign growths of the liver

Common benign growths are Haemangiomas, FNH and Adenoma. Most of these are identified when a scan is performed as investigation for some other problem. Accurate diagnosis of the nature of these lumps is important to determine the type of treatment needed. This can be ascertained by a carefully selected scan like an Ultrasound, CT scan or an MRI. The technology of these scans is continuing to evolve and get better year on year. There are different types of Ultrasound, CT and MRI scans with different applications, based on whether contrast is used or not, the different phases of scanning, the type of MRI scanning sequence etc. Therefore, these scans although commonly available and used very frequently, need to be performed under the supervision of a team involving Liver doctors and radiologist who is well versed in the diagnosis of liver lumps, for accurate diagnosis without the need for unnecessary tests (Box 1).

Haemangiomas are by far the commonest. It is estimated that 5% of the adult population harbor this lump in their livers! They occur in both sexes and at all ages but are commonest between 30 to 50 years in women. Most of them are small, less than 4-5 cms in diameter and are are identified on Ultrasound. MRI and its various applications is the scan of choice for accurate diagnosis. This is crucial as most of them do not need treatment.

Focal Nodular Hyperplasia (FNH) are the second most common liver lumps. They are usually single and small (less than 4 cms) and occur in women between 35   50 years of age. About 2.5-3% of population harbor this lump in their livers. Special MRI techniques using special contrast agents is diagnostic and the findings are quite distinct from haemangiomas. Again treatment is not recommended apart from selected circumstances. Assessment in a dedicated Liver team is recommended for accurate diagnosis and a proper management plan to be formulated.

Hepatic adenomas (Hepatocellular adenoma, HCA) are rare lumps and occur in 0.2 to 0.3% of the population, again occurring mostly in young women during their reproductive period. They are again solitary and most usually 3-4 ms in diameter.

There are a couple characteristics which make this lump different from the previous 2, there is a strong relation between hormones the development of HCA and some of these HCA can turn into the malignant Hepatocellular carcinoma (HCC). Therefore, accurate characterization and diagnosis of these HCA is essential. Sometimes biopsy of the lump, molecular and genetic tests maybe necessary to determine if the HCA has a high chance of progressing to HCC. Imaging tests are generally adequate, contrast MRI Liver and its different techniques is accurate in diagnosing HCA and sub-typing it, however CT and contrast-enhanced Ultrasound is sometimes necessary along with MRI.

Generally, a HCA in a male is recommended for surgical resection. While in women, discontinuation of the OCP pill/ any other such hormone is recommended for a period of 6 months, if the HCA does not have any worrying features and size is less than 5 cms. IF HCA is larger than 5 cms and has features suggestive of a high risk for change to HCC, surgery is advised. Again these decisions have to be made as a part of a Multi-disciplinary team (Box 1)

Malignant growths beginning within the Liver

As mentioned earlier, usually malignant growths which are seen in the liver spread to it from elsewhere in the body. Hepatocellular cancer/Hepatoma (HCC) is the commonest malignant tumour beginning within the liver, as apposed to those that spread to the liver from elsewhere. It occurs between 40-70 years of age and occurs commonly in men. It is estimated that 17000 new patients develop this tumour every year in India. The vast majority (> 80%) of these develop in patients who have chronic liver disease (cirrhosis). Importantly the number of HCC cases is increasing year on year as cirrhosis due to fatty liver disease, Hepatitis B (3% of Indian population carry this virus, ie nearly 40 million individuals) and alcohol are continuing to increase in India. Nearly overall it is the 4th or 5th most common cause of cancer and the second most common cause of cancer-related death. This is continuing to increase too. We do not have a national policy in India to screen and diagnose these lumps in the liver at an early stage. Most patients present at a late stage when effective treatment is not possible.

Hepatitis B is a vaccine-preventable disease, there are good drugs to treat it and decrease the risk of cirrhosis and HCC in HBV patients, therefore it is important to test for this virus infection. The fatty liver disease can cause chronic liver damage and HCC, regular exercise and consuming a balanced diet can reduce the risk of fatty liver disease.

The usual mode of detection of these growths is when a scan is done for some other reason. Occasionally patients can develop pain in the abdomen or jaundice which leads to an investigation. The treatment of HCC depends on the extent of tumour, the extent of the chronic liver disease (the stage of cirrhosis) and the overall condition of the patient. These patients are best seen, assessed and treated in a team (Box 1) which specializes in the treatment of Liver disease.

The best treatment for HCC is surgery. However, this is suitable only for certain carefully selected patients. This can take the form of liver resection (where a portion of the liver with tumour is removed) or liver transplantation (where the whole liver is removed and a donated liver (full or partial) is replaced into the patient. Indeed surgical has excellent survival rates; more than 75% of patients survive for more than 5 years after resection or transplantation making treatment for these cancers one of the most satisfactory.

Other treatments which can be combined with surgery in selected patients or can be combined with patients not suitable for surgery are different types of Interventional radiological therapy   chemotherapy or radiotherapy delivered through fine catheters introduced into the blood vessels of the liver (TACE: Transarterial chemotherapy, TARE: Transarterial radiotherapy) and or heat energy delivered to the tumour area by means of carefully placed needles/probes (RFA: radiofrequency ablation, MWA: microwave ablation).

HCC is unique cancer as its treatment should be tailored to the patient, the treatments are varied and range from catheter-based non-invasive treatment to major surgery and transplantation. This necessitates that HCC patients are best managed in a multidisciplinary team which is highly skilled in and specializes in the management of liver diseases.

Box 1: A liver tumour multidisciplinary team   Integrated Liver Care team

The team should be one with expertise in the management of benign liver lesions and should include a Hepatologist, a Hepatobiliary & Transplant surgeon, Diagnostic and Interventional radiologists, Medical oncologist and a Pathologist.

Each member of the team must hold specific and relevant training, expertise and experience relevant to the management of benign liver lesions.

The team should be one with the skills required not only to appropriately manage these patients but also to manage the rare but known complications of diagnostic or therapeutic interventions.

The Increasing Problem Of Liver Tumours In India!

Pancreas is a small organ that is located in the lower part of the stomach. It lies just behind the abdomen. It functions by producing the insulin hormone which is responsible for regulating blood sugar level in the body and breaking down food into glucagon which is stored in the body. This glucagon is converted into glucose which is used by the body for energy and other purposes. Therefore, pancreatic transplant is done in patients with a malfunctioning pancreas.

Why is pancreatic transplant required?
Patients suffering from type I diabetes usually undergo a pancreatic transplant. Type I diabetes is characterized by the inability of the pancreas to produce insulin, thereby leading to low blood sugar level. This type of diabetes occurs due to the malfunction of pancreatic beta cells whose primary role is to produce insulin. These beta cells make up around 65 to 80 percent of the cells found in the pancreatic islets. They typically malfunction when the body's immune system begins to attack and destroy the pancreatic beta cells. Therefore, type I diabetes is an autoimmune disorder. Patients with type I diabetes require insulin injections that might cause severe reactions. People dependent on insulin are prone to the development of diabetic retinopathy and diabetic nephropathy.

People with type II diabetes generally do not need pancreatic transplant because this type of diabetes occurs due to low production of insulin or lack of insulin resistance. Here is a list of the probable reasons why pancreatic transplant is required:

People who have type I diabetes but are not cured by standard treatment
Severe reactions to insulin injections
Low blood sugar
Kidney damage
Hypoglycemia unawareness
A pancreatic transplant can be of three types. They are:

Pancreas transplant only- People with type I diabetes and normally functioning kidneys require only a pancreatic transplant.
Pancreas and kidney transplant- Type I diabetes, in rare cases, leads to end-stage renal disease (ESRD) or end-stage kidney disease where one or both the kidneys are damaged. In such cases, pancreas and kidney are transplanted simultaneously to disable the dependence on insulin injection. This type of surgery may also be required when the pancreas and the kidneys come from the same donor.
Pancreas-after-kidney transplant- In some cases of type I diabetes, your doctor will recommend kidney transplant first followed by pancreatic transplant. It must be remembered that pancreatic transplant should be done by taking into consideration the side-effects caused by the anti-rejection injections administered after the procedure is performed. It may cause bone thinning, high cholesterol and high blood pressure in a patient s body. As the anti-rejection injections work by suppressing the immune system, the body s defense mechanism against infections and other diseases becomes ineffective to a considerable extent.
A pancreatic transplant is a serious procedure that requires a lot of deliberations and consultations with your doctor and should only be opted for when the benefits outweigh the side effects from the anti-rejection medications.

Pancreatic Transplant - When Is It Required?

The term cirrhosis refers to liver scarring due to various diseases and conditions such as chronic alcoholism and hepatitis. Each time the liver gets injured, it tries to repair itself, resulting in the formation of the scar tissue. With the progression of cirrhosis, a number of tissues generate making the task of liver difficult. Since the liver is an important organ of the body due to its functionalities such as detoxification and nutrient generation, reduced function of liver poses a serious threat to the body.

Symptoms of liver cirrhosis:
Unfortunately, cirrhosis doesn t portray any conspicuous symptoms that can be easily identified until the scarring has reached a level of threat. Some of the common signs and symptoms of this disease include fatigue, nausea, itchy skin, drowsiness, enlarged breasts, testicular atrophy, fluid in the abdomen, bleeding from the mouth, leg swelling, redness in palms etc.

Causes of liver cirrhosis:
There could be an array of reasons for the occurrence of liver cirrhosis. The major causes include an accumulation of fat in the liver, chronic alcoholism and chronic hepatitis. Some of the other reasons include cystic fibrosis, bile duct deformation, Wilson s disease, hemochromatosis, schistosomiasis, continuous consumption of medicines such as methotrexate, a disease involving glycogen storage and Aalagille syndrome.

Complications involved in liver Cirrhosis:

High blood pressure: Cirrhosis results in slow blood movement through the passage of the liver resulting in an increased pressure on the vein that is responsible for carrying blood from the intestine to the liver. This increases the blood pressure in the body.
Swelling of abdomen and legs: Portal hypertension can result in accumulation of fluid in the leg and the abdomen due to the liver s inability to producing an important protein known as the albumin.
Spleen enlargement: Portal hypertension is responsible for changing the shape of the spleen. Decreased count of WBC and the platelets indicate towards portal hypertension and cirrhosis.
Bleeding: Portal hypertension doesn t let the blood flow in its normal path. It directs the blood to flow through smaller veins. The veins, in turn, swell and burst to cause a massive amount of bleeding.
Apart from these some of the other complications involve jaundice, liver cancer, infections, bone diseases and liver failure.

Diagnosis:
Liver cirrhosis doesn t get detected easily. It is often diagnosed with a routine blood test. Some of the lab tests that can help to identify cirrhosis include blood work to check organ function of liver and kidney. Your doctor might suggest other tests such as MRI scan, CT scan or liver biopsy.

Treatment:
Treatment for the underlying cause of liver cirrhosis is done to keep the disease under control. A doctor might treat you for weight loss, alcohol dependency, complications related to hepatitis, portal hypertension and hepatic encephalopathy. For advanced cases where the liver stops functioning, a doctor might suggest a patient go for a liver transplant.

Liver Cirrhosis - What You Must Know About It?

Bladder stones, not to be confused with kidney stones, are formed when substances such as calcium oxalate found in urine coalesce into solid lumps and form deposits in the bladder. Though usually small enough to be excreted during urination, sometimes they get trapped in the neck of the bladder. In such cases, as the residues continue to grow larger, they cause extreme pain, infections, and may need surgical attention.

What causes bladder stones?
The most common causes of bladder stones are-

A diet which is high in oxalic acid can cause bladder stones.
Dehydration and a reduced intake of water cause bladder stones.
A protracted use of a urinary catheter, infections of the urinary tract, or an injury that might have impaired bladder function can cause stones to form.
Most often, stones originate somewhere else in the urinary tract and move downwards obstructing the neck of the bladder. There are significant hereditary factors at play here.
Symptoms-

Blood in the urine usually apparent only in the last few drops.
Interruption of the stream of urine and an inability to do so except in certain positions.
Dark-coloured urine.
Diagnosis-

1.Physical Exam
The physician will physically examine to evaluate if the bladder or the rectum are enlarged.

2.Urinalysis
A sample of your urine will be tested for the presence of bacteria, blood and crystallized minerals.

3.CT scan
A CT scan to build a detailed image of the internal organs.

Treatment-

If the size of the bladder stones is small then a simple increase in water and fluid intake should be enough to excrete them out naturally.
If they are too large to flush out from the system naturally, they will either be broken down to smaller sizes using laser ray or similar other energies, or surgically removed.
In order to prevent bladder stones from recurring, here are 5 foolproof methods-

1.Increase the daily fluid intake
A sure-fire way to prevent bladder stones is to increase the amount of water you drink every day. The idea is to reduce the concentration of your urine. A minimum of 2-3 litres of water per day is absolutely necessary.

2.Urinate more often.
If you drink more water throughout the day, you are going to have to urinate more frequently anyway. Do not put it off because you are worried that you will be mocked for having an old lady s bladder.

3.Laxatives.
If you feel like you are constipated, use a laxative. There is no shame in wanting to regulate your bowel movements.

4.Regular Tests.
Get a sample of your urine tested regularly to ensure that your kidneys and bladder are functioning properly and there are no irregularities.

5.Eat fruits.
Get the essential sugar component of your diet from fresh fruits. Say no to saturated sugar and fizzy drinks. Opt for fruits with high water content like melons to add more fluids in your diet.

5 Full-Proof Methods To Prevent Bladder Stones!

A bladder infection is a bacterial infection within the bladder. Some people call a bladder infection a urinary tract infection (UTI). This refers to a bacterial infection anywhere in the urinary tract, such as the bladder, kidneys, ureters, or the urethra. While most cases of bladder infection occur suddenly (acute), others may recur over the long term (chronic). Early treatment is key to preventing the spread of the infection.

What causes Bladder Infection?
Bacteria that enter through the urethra and travel into the bladder cause bladder infections. Normally, the body removes the bacteria by flushing them out during urination. Men have added protection with the prostate gland, which secretes protective hormones as a safeguard against bacteria. Still, sometimes bacteria can attach to the walls of the bladder and multiply quickly. This overwhelms the body s ability to destroy them, resulting in a bladder infection.

Other factors can increase the risk of bladder infections for both men and women. These include:

Advanced age
Insufficient fluid intake
Surgical procedure within the urinary tract
A urinary catheter
Urinary obstruction, which is a blockage in the bladder or urethra
Urinary tract abnormality, which is caused by birth defects or injuries
Urinary retention, which means difficulty emptying the bladder
Narrowed urethra
Bowel incontinence
Pregnancy
Diabetes
Symptoms for Bladder Infections

Cloudy or bloody urine
Urinating more often than usual
Foul-smelling urine
Pain or burning when urinating
A frequent sensation of having to urinate, which is called urgency
Cramping or pressure in the lower abdomen or lower back
Bladder infections can also cause back pain. This pain is associated with pain in the kidneys. Unlike muscular back pain, you might experience pain on both sides of your back or the middle of your back. Such symptoms mean the bladder infection has likely spread to the kidneys. A kidney infection can also cause a low fever.

Bladder Infections - Decoding one of the Most Common Gynae Problem in Women

An anorectal abscess is a painful swelling near the anus or in the buttock. The swelling contains pus. 60% anorectal abscesses are superficial and resulting from infection in small anal glands present in between internal and external anal sphincters (intersphincteric space). They are known as a perianal abscess. 30% of anorectal abscesses are deep-seated and results in systemic infection. They are call Ischiorectal abscess. Submucous abscess, pelvirectal abscess and pilonidal abscess developed from versatile cause are comparatively less common. Inadequate and improper management of anorectal abscess may potentially cause complication like fistula formation.


Fast facts on Anorectal abscess-

* Anorectal abscess should be drained at the earliest.
* Conservative medical management almost invariably invites complication like fistula formation.
* Surgical drainage of pus reduces the chance of fistula formation by 50%.


What causes Anorectal abscess?

* Blocked and infected anal glands (cryptoglandular infection).
* Untreated anal fissure that becomes infected.
* Sexually transmitted infections.
* Penetrating injury of the perianal or buttock region.
* Crohn s disease.
* Colon cancer.
* Tuberculosis.



What are the symptoms of Anorectal abscess?

Superficial abscess-

* Constant and throbbing pain that worsens on sitting down.
* Swelling, redness and tenderness of the skin around the anus.
* Discharge of pus.
* Pain is often associated with bowel movement.

Deep abscess-

* All or some of the symptoms of a superficial abscess.
* Fever with chill and rigor.
* General weakness.
* Sometimes fever is the only symptom of the deep abscess.

The anorectal abscess should preferably be explored under general or spinal anesthesia. Medical management often fails and subsequently fistula is formed.
