Infection - 1% | Recurrence - 2%
27
What leads to testicular atrophy after a hernia repair?
Dissection of the distal component of the hernia sac causing vessel disruption. Thrombosis of spermatic cord veins.
28
Pain after IHR is usually cause by...
Compression of the ilioinguinal nerve.
29
How do you diagnose/treat pain secondary to ilioinguinal nerve compression?
Local infiltration of anesthetic near the ASIS.
30
What are signs of an ilioinguinal nerve injury?
Loss of cremasteric reflex. Numbness on ipsilateral penis, scrotum, thigh.
31
Where does an ilioinguinal nerve injury occur in IHR?
Usually at the external ring. Nerve runs on top of cord (anterior).
32
What are the signs of a genitofemoral nerve injury?
Genital branch - cremaster (motor), scrotum (sensory) | Femoral - upper lateral thigh (sensory) loss
33
When is the genitofemoral nerve injured?
Usually injured in laparoscopic repair.
34
Cord lipomas in IHR...
Should be removed.
35
Femoral canal boundaries?
Posterior - Cooper's (pectineal) Anterior - inguinal ligament Medial - lacunar ligament
36
Space that femoral hernia fills?
medial to femoral vein, lateral to lymphatics (in empty space)
37
Maneuver to reduce risk of incarceration in femoral hernia?
divide the inguinal ligament
38
Approach to repair femoral hernia?
Inguinal approach with Cooper's ligament repair
39
Femoral hernia - characteristic exam
bulge on the anterior-medial thigh below inguinal ligament
40
Age of repair for umbilical hernia
Delay until age 5 yrs
41
Spigelian hernia - location
Lateral border of the rectus muscle, adjacent to linea semilunaris, inferior to semicircularis; between the muscle fibers of IAO muscle and insertion of EAO apo into the rectus sheath
42
Obturator hernia - presentation
tender medial thigh mass or SBO | XR - bowel gas below superior pubic ramus
43
Howship-Romberg sign
inner thigh pain with internal rotation in obturator hernia
44
Obturator hernia treatment
operative reduction, may need mesh; examine other side for defect
45
Obturator hernia risk factors
elderly women, prior pregnancy
46
Sciatic foramen location
posterior pelvis, through the greater sciatic foramen | High rate of strangulation
47
Posterior rectus sheath absent starting where?
Below semicircularis (below umbilicus). Posterior aponeurosis of IAO & transversalis moves anterior.
48
Rectus sheath hematoma - risk factors
most common after trauma, epigastric vessel injury
49
Rectus sheath hematoma - Presentation
Painful abdominal wall mass, more prominent and painful with flexion of rectus muscle (Fothergill's)
50
Rectus Sheath hematoma - Management
Nonop, surgery if expanding
51
Rectus Sheath hematoma - Types
Type I - small, confined to muscle, does not cross midline Type II - within muscle, but can cross midline or dissect along fascial plane Type III - large, crosses midline, usually below arcuate line. Hemoperitoneum or blood in retropubic space (prevesical space of Retzius)
52
Desmoid Tumors - Presentation/Risk factors
Women, Gardner's Syndrome, painless mass; increased recurrence
53
Desmoid tumors - Surgical Management
WLE if possible, may not be indicated if significant small bowel mesentery involvement
54
Desmoid tumors - Medical Management
Sulindac, tamoxifen
55
Retroperitoneal fibrosis - Risk factors, diagnostic test
Hypersensitivity to methysergide (migraine med) | IVP most sensitive - constricted ureters
56
Retroperitoneal fibrosis - Symptoms caused by
related to trapped ureters & lymphatic obstruction
57
Retroperitoneal fibrosis - Treatment
steroids, nephrostomy if infection present | Surgery if renal function compromised (free up ureters, wrap in omentum)
58
Mesenteric Tumors - Benign vs Malignant locations
Benign - more peripheral | Malignant - closer to root of mesentery
59
Mesenteric Tumors - Most common malignant
liposarcoma
60
Mesenteric Tumors - Dx & Tx
Dx: abdominal CT Tx: resection
61
Retroperitoneal Tumors - Most common malignant types
``` #1 = Lymphoma #2 = Liposarcoma ```
62
Retroperitoneal Sarcomas - Characteristics
<25% resectable. Pseudocapsule, but cannot shell out - would leave residual tumor. Mets go to lung.
63
Omental Tumors - most common solid tumor, management
Metastatic disease | Omentectomy for some cancers (e.g. ovarian)
64
Omental cysts - presentation
usually asymptomatic, can undergo torsion
65
Primary solid omental tumors
Rare, 1/3 malignant No biopsy, can bleed. Tx: resection
66
Mechanism of peritoneal dialysis (peritoneal membrane function)
Blood absorbed through fenestrated lymphatic channels; movement of fluid can occur with hypertonic saline load, can cause hypotension
67
CO2 Pneumoperitoneum - Normal v Abnormal level
Normal = 10-15 | Abnormal >20, IAP where cardiopulmonary dysfunction can occur
68
CO2 Pneumoperitneum increases...
MAP, PAP, HR, SVR, CVP, mean airway pressure, peak insp pressure, CO2
69
CO2 Pneumoperitneum decreases...
pH, venous return (IVC compression), CO, renal flow
70
PEEP in pneumoperitoneum
Can worsen effects
71
CO2 effect on myocardium
Can decrease contractility
72
CO2 embolus - presentation
sudden transient rise in ETCO2, followed by drop, then hypotension
73
CO2 embolus - Treatment
head down, pt turned to left; aspirate CO2 through central line, prolonged CPR
74
Harmonic scalpel
Disrupts protein H-bonds, causes coagulation | Okay for medium vessels (short gastrics)
75
Argon Beam
energy tranferred across argon gas. Depth of necrosis related to power setting, causes superficial coagulation. Non-contact, good for liver & spleen. Smokeless.
76
Laser use in hemostasis, clinical uses
return of electrons to ground state releases energy as heat, coagulates and vaporizes. Clinical - condyloma acuminata (wear mask)
77
Nd:YAG Laser
Good for deep tissue penetration, bronchial lesions | 1-2mm cuts, 3-10mm vaporizes, 1-2mm coagulates
78
Gore-Tex (PTFE) v Dacron
PTFE cannot get fibroblast ingrowth. Dacron allows fibroblast growth.
