- 2. Gastric Lavage Gastric lavage is popularly known as stomach pumping. After a pH test to ensure the nasogastric tube is correctly inserted into the stomach, water or saline is used to wash away the contents of the stomach—either due to an overdose or as a preparation for surgery.
- 3. Hernioplasty Hernia repair may involve simply removing the herniated tissue (herniotomy) or it may also involve repairing the adjacent tissue with the patient’s own tissue or with heterogenous material such as a mesh. What used to be an inpatient procedure is now an outpatient procedure lasting less than a few hours. With the advances in laparoscopic surgery it can even be a relatively non-invasive approach.
- 4. Choledocholithotripsy Lithotripsy refers to the breaking or dissolving of stones, whether in the kidneys or gallbladder. “Choledocho-” refers specifically to the common bile duct. The illustration at right shows that stones may collect in the gallbladder itself, in the cystic duct, or in the common bile duct. Believe it or not, the actual crushing is done by sound waves!

- 6. Anastomosis An anastomosis can be a pathological condition such as a fistula or incorrectly joined capillaries. It may also be a therapeutic procedure. Let’s look at two different therapies that involve creating an anastomosis. This diagram shows a common type of surgical anastomosis known as a Roux-en-Y. It can be used to bypass diseased or damaged areas. It is also a somewhat common technique in bariatric surgery. It has the advantage of being done laparoscopically, and may therefore be safer than “stomach stapling.”
- 7. Anastomsosis, part 2 This type of surgical anastomosis is intended to eliminate the need for a total colostomy. Instead of wearing an external waste pouch the patient is able to lead a more normal life. The Mayo Clinic is known for this approach. http://www.mayoclinic.org/colostomy-sparing-surgery/
