Study Notes

Surgical Sutures and Healing

Philip Syng Physick discovered that the body absorbs sutures made from animal tissues.
Non-absorbable sutures, such as fascia lata, remain in the body as living tissue.
Dead space occurs when wound edges are not closely approximated by sutures.
A mattress suture is made by passing the suture through tissue from one side of the wound to the other and back again.
Non-absorbable sutures become encapsulated by fibrous tissue during the healing process.

Infection and Absorption Rates

Absorption rate of surgical gut increases in the presence of infection.
Polypropylene sutures are suitable for use when infection is present.
Subcuticular sutures involve taking short lateral stitches beneath the skin.

Wound Healing Techniques

Healing by secondary intention involves leaving a wound open to heal from the bottom upward.
Surgical gut is derived from the submucosa layer of sheep's intestines.
Wire sutures are most inert in tissue and do not provoke a reaction.

Surgical Complications

Dehiscence refers to the spitting open or gaping of a wound.
Evisceration is the protrusion of bowel through the edges of an abdominal wound closure.
Silk sutures are discouraged in areas like the gallbladder due to their potential to form stones.

Surgical Techniques and Classifications

The Halsted Technique uses interrupted silk sutures for closure.
Stay sutures do not pass through mesentery tissue.
Bumpers or guards prevent heavy sutures from cutting into the skin.
Sutured swaged to a needle minimizes tissue trauma.

Suture Properties and Techniques

Tensile strength measures the weight required to break suture or ligature material.
Soaking, testing tensile strength, and straightening can weaken sutures.
The least reactive synthetic non-absorbable suture material is polypropylene.

Postoperative Complications

Hypovolemic shock results from post-op GI bleeding; neurogenic shock results from failure of arterial pressure.
Tetany is a serious post-operative problem after parathyroidectomy.
Acute cholecystitis is often due to gallstones, cystic duct obstruction, bacterial infection, or empyema.

Hernias and Surgical Procedures

A direct hernia is a weakness in the fascial margin of the internal ring, while an indirect hernia is a weakness of the fascial floor of the inguinal canal.
The Portacaval shunt is indicated for esophageal varices and backpressure on the portal vein.
Vagotomy for peptic ulcers is typically accompanied by pyloroplasty due to effects on gastric motility.

Digestive System and Surgical Procedures

A two-layer bowel anastomosis involves closing the inner mucosal layer with absorbable sutures and the outer serosal layer with non-absorbable sutures.
Vagotomy with antrectomy or gastroenterostomy is common for peptic ulcers.
Pancreas functions as an endocrine gland, releasing insulin and glucagon into the bloodstream.

Surgical Techniques for Specific Conditions

Whipple procedure is the surgical operation for carcinoma of the head of the pancreas or ampulla of Vater.
Evisceration follows surgical procedures if there's a protrusion of viscera.
Immediate surgery is required for conditions like complete small bowel obstruction and cecal volvulus, but not for massive rectal prolapse.

Hernia Classification and Intestinal Obstruction

Incarcerated hernia obstructs the intestinal flow; strangulated hernia leads to acute obstruction.
Direct hernia involves a defect at the inguinal ring.
Subtotal gastric resection with gastrojejunostomy is known as Billroth II.

Miscellaneous Surgical Knowledge

Diverticulum refers to a saccular dilation of the bowel lumen.
Vagotomy decreases hydrochloric acid secretion in peptic ulcer treatment.
Esophageal varices develop from increased portal vein obstruction, causing venous blood to seek alternative routes to the right atrium.

Bypass Procedures

Roux en Y procedure used for common duct repair is called choledochoduodenostomy.
Portal hypertension surgical bypass can occur between the portal vein and inferior vena cava, or splenic vein and left renal vein.

Complications and Causes of Intestinal Obstruction

Colitis does not cause intestinal obstruction, unlike intussusception and cecal volvulus.

Thyroid Function

Clarification is needed on the statements regarding thyroid physiology and pathologies, as one provided is not true.
