Procedures
Appendectomy

Appendectomy is a surgical procedure in which the inflamed appendix causing abdominal pain is removed. An appendix is a pouch-like structure attached to the large intestine and is located on the lower right side of the abdomen.

An appendectomy can be done laparoscopically as well as an open procedure. Complications may arise if an appendix has burst due to inflammation, which may increase the recovery time as a drain is put in the incision for a few days after the surgery.

Hemicolectomy

The last part of the gastrointestinal system is referred as the colon and it is 5-6 cm long. It is ‘U’ shaped and it starts from the distal part of the small intestine and is connected to the rectum and anus. It absorbs the fluids, processes the metabolic waste products, and eliminates through the rectum and anus. The removal of the colon is called colectomy.

There are different types of colectomies such as complete colectomy,  right hemicolectomy, left hemicolectomy, sigmoid colectomy, and proctocolectomy. The surgical removal of the left side of the colon (descending colon) is called left hemicolectomy surgery. The surgical removal of the cecum, ascending colon, and the hepatic flexure (right side of the colon) is called as the right hemicolectomy surgery.

Some of the conditions that require complete colectomy or hemicolectomy surgery include the following:

  • Colon cancer
  • Crohn’s disease
  • Blockage of the colon
  • Precancerous polyps
  • Hereditary polyps
  • Benign tumours
  • Irritable bowel syndrome (IBS)
  • Gastrointestinal bleeding
  • Bowel twisting and obstruction
  • Ulcerative colitis
  • Appendicitis with inflammation of the cecum
  • Right-side colonic diverticular disease (diverticulosis)

A hemicolectomy procedure can be performed as a laparoscopic or open surgery. The type of the surgery to be performed is decided by the surgeon during the evaluation and the decision depends on the age and the condition of the patient.

Sometimes the laparoscopic procedure can also be turned into open surgery, depending on the feasibility of the procedure with respect to safety and accuracy. Overall, the following parameters decide whether a laparoscopic or an open surgical procedure will be performed:

  • Age
  • Diagnosis
  • Medical history
  • Personal preference
Inguinal Hernia Repair

Inguinal hernia is a condition that occurs when intestinal tissues or fatty tissues push through the weaker section of the abdominal wall, through the inguinal canals. The inguinal canals are situated both sides of the anterior abdominal wall, on either side of the midline. Located just above the inguinal ligaments, the inguinal canal is larger as well as more prominent among the men compared to women. It serves an important purpose, as it is associated in the conveyance of the spermatic chords in male as well as the uterine ligament (round) in the females. When a part of the abdominal wall gets weak, the tissues in the region protrude through the abdominal wall into the canal, causing extreme pain and discomfort. This can be felt as a lump in the lower abdominal area in most people, however, may also get unnoticed in candidates dealing with obesity. In such cases, inguinal hernia repair becomes the need of the hour, which can be achieved by surgical operations.

Inguinal hernia can be very painful and may interfere with daily activities to a great extent. Though medications like painkillers may help to cope up with the pain, the best treatment to cure hernia is through surgical procedures. Inguinal hernia repair can be done via surgical methods as the opening can not be sealed with medications and therapies, and needs to be thoroughly sealed. Thus, the candidate is suggested and requested to prepare for surgery. However, pre-surgery, through evaluation of the candidate is done in order to diagnose any kind of chronic or terminal disease which shall complicates the surgery further. Inguinal hernia repair is essential as if the protruding tissues are not retracted, it will keep forcing the opening in the abdominal and worsening the condition.

Laparoscopic Gall Bladder Removal

Laparoscopic gallbladder removal is a minimally invasive surgery in which small incisions and specialized tools are used to remove a diseased or inflamed gallbladder. The gallbladder is a small organ located in the right upper abdomen below the liver. It helps in the storage of bile which is used to breakdown food during digestion. Laparoscopic gallbladder removal is a minimally invasive surgery in which small incisions and specialized tools are used to remove a diseased or inflamed gallbladder. The main reason for having a gallbladder removed is the presence of gallstones and the complications it might cause. Other reason for the surgery might include biliary dyskinesia, cholecystitis, pancreatitis. It is called as laparoscopic cholecystectomy and it carries only a small risk of complications.

Laparoscopic Hernia Repair
Prostatectomy

The prostate gland is present below the urinary bladder in men. It surrounds the urethra and produces fluid that helps in the movement of the semen. Prostatectomy is a surgery that involves total or partial removal of the prostate gland. It is commonly performed as a part of treatment for prostate cancer.

Types of Prostatectomy

Radical prostatectomy: This surgery involves the removal of the entire prostate gland along with the surrounding lymph nodes. The surgical techniques used to conduct radical prostatectomy include the following:

  • Robot-assisted surgery: In this technique, several small incisions are made in the lower abdomen to remove the prostate gland.
  • Open surgery: In this technique, an incision is made in the lower abdomen between the anus and scrotum to remove the prostate gland.
  • Laparoscopic: In this technique, special surgical tools are inserted in the lower abdomen to remove the prostate gland.

Open simple prostatectomy: This surgical procedure involves removal of just the affected part of the prostate gland and is recommended for men with the cancerous prostate gland or benign prostatic hyperplasia (BPH).

Indications

  • Prostate cancer
  • Urinary tract infection
  • Bladder stones
  • Hematuria
Trans Urethral Resection of Bladder Tumor (TURBT)

Cancer in Bladder can be found to vary depending on the type of its origins. It can arise from the lining of the epithelium which is the inner lining of the urinary bladder or the urothelium. Rare forms of cancer are not of epithelial origins like the sarcoma or lymphoma. Tumours in bladder is found to be the 9th leading type of cancer in United States as per a survey conducted in 2012 with 430,000 new cases and mortality of 165000 deaths annually.

About Trans Urethral Resection of Bladder Tumor

The first and foremost question to ask is where is your bladder located? The sac like muscular urinary bladder is located in the pelvis region above the pelvic bone. It is connected to the kidneys through the two ureters that transfer the urine from the kidney to the bladder for storage. An abnormal growth of cells in the inner lining causes a tumour requiring diagnosis and then followed by a turbt surgery.

In most cases the tumour cannot be assessed in the primary stages. There are hardly any notable evidences found when the patient is harbouring a primary tumour.

The next stage is designated as Oa and categorized as a non invasive type papillary cancer.
In the stage next of the stage 0 or the carcinoma in situ the inner lining of the bladder is affected and is still considered non invasive.
In stage I the cancer has spread into the lining of the bladder further but has not affected the muscular wall of the bladder.
While in Stage II the inside part gets affected including the muscles of the bladder making it now invasive.
And when the cancer has spread enough in muscles and the tissues around the bladder like the reproductive organs it is considered to be in stage III.
And in the final or stage IV the cancer will spread to the lymph nodes affecting the organs around it as well.

Causes of developing a tumour in bladder

The causes of tumour in bladder are not always very clear and well defined but it has been linked with smoking, chemical exposure and radiation or a parasitic infection. The abnormal cells undergo some mutation that allows them to multiply in a non orderly fashion and goes beyond control and they do not die thus giving rise to the tumour.

Symptoms of the TURBT

A person suffering from a tumour will experience mild sensation of burning and discomfort in the times of urination for quite a few days. The force of the urinary stream may also undergo significant changes which can be observed for a week to a fortnight. Usually there could be none of the symptoms and in certain cases all symptoms even if experienced may not lead to the conclusion that it is a bladder cancer. There can be blood or clots of blood in the urine along with a tendency of urinating too frequently. Tendency of urinating at night may be felt more but there can be general problems in urine passing. Associated along with this the patient can experience pain on either side of the body.

What is transurethral resection of bladder tumour?

This procedure aims at removing bladder tumours at an early stage by inserting a scope through the urethra leading to the bladder. In the TURBT procedure bladder cancer can be detected by the urologist and potentially allow the urologist to treat various other kinds of bladder related disorders. But 75% of the cancer of bladders that are detected are superficial in nature causing growth only on the surface of the walls of the bladder and does not get very deep. So this facilitates the surgeon to have the tumour removed at the bladder wall level causing no damage to the deeper layers of the organ. The information that is collected while executing the procedure will help the surgeons to decide the type of the abnormality of the tumour and the extent of the tumour. This later allows the urologist surgeons to decide whether further treatments will be required or not.

What are the alternatives for TURBT procedure?

Some of the other treatment alternatives for TURBT are being worked upon while some of them have tremendous side effects

Blue light fluorescent cystoscopy : Enhanced tumour visualization is possible and detection of tumour chances are increased by almost 20 to 25% with this method where an ultraviolet blue light is used. A dye is injected an hour prior to the procedure.

Adjuvant bladder cancer therapy: TURBT is not suitable for many who have high chances of suffering a recurrence within 12 months from the treatment. In this case adjuvant therapy is recommended. It includes intravesicle chemotherapy. Chemotherapy for bladder cancer includes giving medication to curb the abnormal growth of cells. But it also has its sets of side effects like experiencing irritation in bladder and loss of hair, nails and feeling debilitated for a very long period of time.

Trans Urethral Resection of Prostrate (TURP)

The enlarged prostate gland can become a subject of concern after a certain age in men. It causes trouble while urinating and that is one of the main reason why such men are advised to undergo trans urethral resection of prostate (TURP) surgery.

What is Trans-Urethral Resection of Prostate (TURP)?

The prostate gland goes through two phases as a man grows old. The growth phase occurs during puberty when the gland assumes double its size. The second phase of growth takes place after a man has attained the age of 25. This final size at this stage continues to remain the same throughout the life. But when men suffer from benign prostatic hyperplasia, the prostate gland gets further enlarged.

When the gland enlarges, it squeezes the urethra and as a result, the wall of the bladder grows thick. With time, the bladder grows weak and loses its ability to empty the urine completely. This allows some urine to stay back in the bladder at all times. Along with this, the urethra also narrows and hence, all the problems associated with urination keep coming back.

As of now, it is not totally clear why most men develop BPH but it mainly indicates an imbalance of hormones and sexual activities with advanced age. Apart from that, there can be urinary tract infection, narrowing of the urethra known as urethral stricture, inflammation of the prostate, bladder or stones in the kidney, nerve problems in controlling the bladder, or scarring in the neck of the bladder as a result of previous surgery.

The following are some of the symptoms of BPH:

  • Frequent urge to urinate

  • Difficulty in initiating urination
  • The urine stream that flows is weak and stops and starts in the session
  • At the end of urination, dribbling is often experienced
  • Straining is felt at the time of urination
  • Blood in the urine
  • Inability to completely empty the bladder
  • Infection in the urinary tract

Some of these above symptoms can occur even in men whose prostate has not enlarged significantly.

Whipple's Procedure

Among all the forms of common cancers, it has been found that pancreatic cancer has the poorest prognoses. This reason can be attributed to the cancer growing and spreading long before it starts showing any visible symptoms. A survey revealed that only 6 percent patients survive for more than five years after its diagnosis. For some patients, a very complicated surgery known as the Whipple's procedure will be able to extend life and can be counted as a potential cure. After undergoing Whipple's surgery the five-year rate of survival can be increased to 25 percent.

People who are suffering from pancreatic cancer are eligible for the Whipple’s operation. People who have tumors confined to the pancreatic head and the blood vessels, lungs, and livers or the abdominal cavities are still not affected and are recommended to undergo this procedure after intensive testing and evaluation.

People with benign tumors are also recommended to undergo the procedure. For patients who are suffering metastasis, this procedure is not recommended. Cancer in the ampulla, region where the pancreatic duct and bile duct enter, can also be treated.

Whipple's Operation

Whipple's operation is conducted in the head of the pancreas. During the surgery, a segment of the duodenum, bile duct, and the gallbladder is removed. In some cases, a portion of the stomach may also be removed. After these segments are removed, the remaining pancreas, bile duct, and even portion of the intestine will be sutured back to the main intestine to direct the secretion of the gastrointestinal segment into the gut. The Whipple& procedure for pancreatic cancer is long and has several complications associated with it.

A doctor may recommend you to undergo Whipple operation for the treatment of the following conditions:

  • Pancreatic cysts, tumors, and cancer
  • Ampullary cancer
  • Pancreatitis
  • Neuroendocrine tumors
  • Cancer of the bile duct
  • Small bowel cancer
  • Traumatic injury to the small intestine or the pancreas
  • Tumor of disorders of the bile ducts, pancreas, or duodenum
