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.

Gastric Bypass

Nowadays, weight management is the biggest problem for people from all age groups. Weight loss surgery options are preferred when alternative means of weight loss such as exercise, diet management, and so on fail to work.

Gastric bypass, also known as Roux-en-Y Gastric Bypass, is one of the most popular weight loss surgery options during which the size of the stomach is decreased. The reduced size of the stomach allows for reduced consumption of food by the patient, which in turn, results in gradual weight loss.

Other popular weight loss surgery options include:

  • Sleeve gastrectomy
  • Adjustable gastric band
  • Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

Of all the bariatric procedures, gastric bypass is the most preferred options for weight loss because of the greater possibility of positive outcomes. Moreover, there are no major side effects of gastric bypass.

 What are the criteria for gastric bypass surgery?

 Not everyone is an ideal candidate for gastric bypass surgery. People with a body mass index (BMI) of 40 or more and with a history of heart disease, obesity, and obstructive sleep apnea are mostly recommended gastric bypass surgery.


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.

Lap Gastric Banding

Obesity has become a growing concern for individuals in the present generation. Surgical intervention is one of the options for weight loss that obese individuals can opt for.

People prefer to choose surgical options for weight loss mostly when they fail to achieve satisfactory results through other methods such as exercise and diet control. There are different types of surgeries for weight loss, demand for which has steadily risen since last few years. One such type of surgery is the gastric banding procedure.

Gastric banding procedure is a minimally invasive surgery conducted with the help of a laparoscope. This surgery involves the placement of a weight loss band that restricts the passage of the food from the stomach to the intestine. It is commonly called as a lap-band or laparoscopic adjustable gastric band (LAGB).

The weight loss band used during the gastric banding procedure is actually an inflatable silicone device with a tendency to expand and contract. Your doctor can adjust the weight loss band from the outside such that only small amounts of food can pass through the stomach.

  • The adjustable gastric band makes you feel full earlier and thereby, aids in gradual weight loss. The gastric band may not result in quick weight loss and you must modify your lifestyle, follow a proper diet and exercise regularly.
  • Gastric banding procedure is an alternative to vertical sleeve gastrectomy, in which a large portion of the stomach in removed to aid in weight loss. Gastric band removal is possible, but you are not advised to opt for it upon reaching the targeted body weight.
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
Sleeve Gastrectomy

Gastric sleeve procedure, also known as sleeve gastrectomy, involves surgical removal of part of a stomach. This procedure is a permanent one and intends to result in drastic weight loss in individuals suffering from morbid obesity.

During the gastric sleeve procedure, the left side of the stomach is cut and the size is reduced to just 25 percent of its original size. The resulting stomach looks like a banana-like “sleeve.”

The resulting vertical gastric sleeve limits the intake of food due to reduced production of gastric enzymes and digestive juices. You may feel full after eating small amounts of food. This is also known as a “restrictive procedure” as it restricts the amount of food that you can consume at a time. This procedure is performed laparoscopically and is irreversible in nature.

Is it safe to have sleeve gastrectomy?

Gastric sleeve procedure is recommended to individuals whose body mass index (BMI) is 40 or greater than 40. It is a completely safe procedure and is minimally invasive in nature.

When performed correctly, laparoscopic sleeve gastrectomy improves a number of obesity-related medical conditions, including low back pain, arthritis, hypertension, cardiac disorders, obstructive sleep apnea, dermatitis due to skin folds, urinary incontinence, and metabolic syndrome.
