Common Abdominal and Chest Surgeries Flashcards
What is the main difference between open surgery (laparotomy) and laparoscopy?
Size of incision
Laparotomy: single incision multiple inches long
Laparoscopy: minimally invasive with several incisions one-quarter or less
What is the difference between laparoscopy and laparotomy as far as recovery?
Laparotomy: longer recovery, hospital admission
Laparoscopy: less blood loss, less trauma, faster recovery, many can go home that day or after 23 hr OBS, can be more $
how is a patient selected for laparotomy vs laparoscopy?
Overall health
BMI
Prior surgeries
What is used for scoring of appendicitis and what score has a high index of suspicion?
Alvarado score
7-10
Common cause of appendicitis
Fecalith/appendiceal obstruction
Can be cancer
Work up of appendicitis
Labs: leukocytosis + left shift
U/S: initial imaging modality in children when body habitus permits
+/- abdominopelvic CT scan with oral contrast if concerned for perforation
Indications for appendectomy
Standard of care for acute appendicitis
Som may elect for conservative non op management if uncomplicated non perforated appendicitis, but 30% have recurrent appendicitis within 1 year
What abx would be given if a patient opts for non op management of appendicitis
IV abx for 1-3 days followed by oral
Ceftriaxone + metronidazole IV
followed by fluoroquinolone + metronidazole, 3rd gen cephalosporin + metronidazole or augmentin oral
What is the psoas sign?
Extend hip and see if pain
A patient should do what prior to appendectomy?
Void bladder to prevent bladder injury
Procedure of laparoscopic appendectomy
Pneumoperitoneum via Veress needle or open Hassan
Laparoscope inserted into abdomen and 2 additional ports placed: one in LLQ, one in suprapubic region
Patient positioned in trendelenburg with left side of table down to pull small bowel away from cecum
Abdomen inspected and cecum ID
Cecum grasped and appendix IDd
Mesoappendix grasped and divided with endoscopic stapler
Endoscopic stapler used to remove appendix from cecum
Abdomen irrigated and inspected for bleeding
If hemostasis satisfactors, ports removed under direct visualization, fascia and skin closed, dressings applied
Laparotomy appendectomy procedure
Dissection through Camper and Scarpa fascia
External abdominal aponeurosis exposed and incised
External oblique split
Internal oblique muscle and transversus abdominis split to expose transversalis fascia and peritoneum
Transversalis fascia and peritoneum grasped with 2 straight clamps
Incision with Metzenbaum scissors and peritoneal cavity entered
Appendix mesoappendix complex freed and mesoappendix ligated
Post appendectomy care
Can d/c home same day with nonperforated/uncomplicated lap appy
Admit for perforation or open technique
Abx
What abx are used for non-perforated/uncomplicated lap appy? What about perf-postop?
Lap-appy: single preop dose
perf-postop: ceftriaxone and metronidazole x5-7 days
Indications for cholecystectomy
Symptomatic cholelithiasis, may also require intraoperative cholangiogram
Asymptomatic cholelithiasis if increased risk of GB carcinoma or gallstone complications
Acalculous cholecystitis
Gallbladder polyps >.5 cm
Porcelain gallbladder
Contraindications for cholecystectomy
Diffuse peritonitis
Hemodynamic compromise
Uncontrolled bleeding disorders
Most common indication for open chole vs lap chole
Inability to safely perform a lap chole or highly suspect cancer
have hemodynamic conpromise and will not tolerate introp pneumoperitoneum
work up of cholecystectomy
RUQ US
+/- abdominal CT scan
Labs
+/- MRCP
+/- ERCP
Complications of cholecystectomy
Common bile duct injury/CBD leaks/obstruction
Bowel injury
Liver injury
Intra-abdominal abscess
Bleeding
dyspepsia and diarrhea
When should you suspect common bile duct injury/CBD leaks/obstruction
fever
abdominal pain
2-10 days postop
may lead to peritonitis/infection
how would you confirm common bile duct injury/CBD leaks/obstruction
U/S or CT
how is common bile duct injury/leak/obstruction treated?
U/S guided percutaneous drainage with ERCP to stent or repair OR re-operation
post-op care if uncomplicated lap chole
d/c home same day
give po pain meds no abx needed
f/u in office in 5-7 days
post-op care if open or complicated lap chole
admit for 1-3 days
pain meds
typically no abx needed unless surgery contraindicated
monitor for complications
common colon surgeries
right colectomy: cecum, ascending colon, hepatic flexure, first portion transverse colon
left colectomy: second portion transverse colon, splenic flexure, descending colon, sigmoid colon
total colectomy
sigmoid colectomy
proctocolectomy: includes the anus
colostomy
indications for colon surgery
tumors/masses
ulcerative colitis
diverticulitis/perforation
ischemic colitis: vasculopath, intestinal volvulus/obstruction
work-up for colon surgery
PE- palpable mass?
Labs: tumor markers (CEA/CA 19-9)
Colonoscopy
CT abdomen and pelvis w/IV and oral contrast
What are reasons for benign disease colectomy?
IBD
Diverticular disease
Rectal prolapse
Colonic dysmotility
What are neoplasia reasons for colectomy?
Polyps not amenable to resection via colonoscopy
Colorectal cancers
Hereditary colon cancer syndromes: familial adenomatous polyposis and hereditary nonpolyposis colorectal cancer
Compared with open colectomy, laparoscopic surgery has been shown to be associated with decreased ….
post op pain and analgesia requirement, faster return of bowel function, earlier resumption of PO intake, shorter hospital stay, and better cosmesis
What are the drawbacks of laparoscopic colectomy?
Time consuming –> greater expense and require specialized training
Complications of colectomy
Anastomotic leak
Intra-abdominal abscess
Bleeding
Bowel obstruction
