Open Sx Appendectomy

A
  1. McBurney/Lanz/Rocky Davis Incision
  2. Identify the cecum
  3. Deliver the appendix into the wound
  4. Control mesoappendix, divide appendix control base - purse string suture

***Higher rate of local wound infection

21

  9. DIVERTICULITIS
23
Q

Wth is the diverticula? Really doe?

A

Outpouching of weakened colon at site of vascular perforation. Typically the left (sigmoid) colon.

Commonly seen in older adults, but becoming more common in the young. When obstruction occurs, bacterial overgrowth can happen.

24
Q

So wth is diverticulitis then?

A
  1. Presents with abdominal pain, bright red blood per rectum, fever, elevated WBC
  2. May form contained abscess amenable to CT drainage which may or may not be followed by operation
  3. May require urgent operation (sigmoid colectomy-Hartmann’s procedure)
25
Q

Crohn’s Dz (Inflamm Bowel Dz)

A
  1. May affect mouth to anus, but usually spares rectum
  2. Presents with diarrhea, usually not bloody
  3. Transmural inflamm dz with cobblestoning and ulcers
  4. Dx with colonoscopy
  5. Inc risk of cancer
  6. Management is Medical (Anti inflamma, steroids)
  7. Surgical management only for bowel obstruction unresponsive to med management or if perforated
26
Q

Ulcerative Colitis (Inflamm Bowel Dz)

A
  1. Colonic Inflammation, involves rectum
  2. Presents with diarrhea and red blood per rectum
  3. Friable mucosal dz with pseudo polyps
  4. Dx by colonoscopy with bx
  5. Inc risk of cancer
  6. Management is Surgical (total proctocolectomy with end ileostomy of ileal J-pouch)
27
Q

When are ileostomies/colostomies used?

A

In situations where anastomosis between segments of bowel is no feasible or is unsafe, such as

  1. Contamination (trauma/perforation)
  2. Concern regarding blood supply
  3. Grossly dilated bowel (toxic megacolon, bowel obstruction)
  4. When further operations on a segment of bowel are planned (imperforate anus)
28
Q

Post-op concerns of ileostomy or colostomy placement

A
  • Ileostomy – Fluid loss, inability to absorb B12, Vit ADEK
  • Colostomy – Loss of capacity to reabsory

-Both: Skin irritation, prolapse, parastomal hernia

29
Q

Closing the Abdomen

A
  1. Count! Lap pads, instruments, malleable

A
  1. Running Suture

2. Interrupted suture

31
Q

What do you do for a Skin Closure?

A
  1. None
  2. Stapled
  3. Suture (Interrupted, Running, Subcuticular)
