- Treatment - ANSWER - Define: sub-ungal AV fistula
- Presentation Triad: pain, cold insensitivity, tenderness on palpation
- Two Key Signs
1. Love's = point tenderness
2. Hildreth's = relief with insufflation
- Treatment: surgery
Inguinal Hernia
- Recurrence with/without mesh
- Risk of incarceration each year - ANSWER - Recurrence with/without mesh = 5 vs. 20%
- Risk of incarceration each year = 0.18%/year
Procidentia
- Etiology (2)
,- Recognizing full vs. mucosal prolapse
- Definitive Test
- 3 Treatments + Description - ANSWER - Etiology (2)
1. Pudendal nerve injury
2. Laxity of anal sphincter
- Recognizing full vs. mucosal prolapse
1. Full = circular folds
2. Mucosal = linear folds
- Definitive Test = defecating proctogram
- 3 Treatments + Description
1. Transanal Excision = Altemier (incision 2cm above dentate line to open peritoneum, then tack
peritoneum at level to puborectalis)
2. Delorme (ideal of older patients): Mucosal excision + muscular plication
3. LAR with Sigmoid Pexy
Biliary Dyskinesia
- When to suspect?
- Describe method
- Treatment - ANSWER - When to suspect?
Signs/symptoms of biliary colic with negative USG, CT, ERCP
- Describe method
Gallbladder gets filled with Tc99, infuse CCK. If EF <35% at 20min = diagnosis
- Treatment = lap chole
Injecting dye before WLE melanoma/breast:
- When to inject?
- Where to inject (layer of skin)?
- Why not inject after WLE? - ANSWER - When to inject? hours before procedure
- Where to inject (layer of skin)? dermis, where lymphatics are
- Why not inject after WLE? b/c WLE disrupts the lymphatic pathways
Post-Hemorrhoidectomy Bleeding Etiologies/Mgmt
- Early (<24hrs)
- Late (>POD5) - ANSWER - Early (<24hrs): likely to be surgical error, needs evaluation
- Late (>POD5): likely to be eschar from surgery falling off, no intervention
,Esophageal CA Review
- Why so malignant (aka how do they spread?)
- Test to Diagnose?
- Test to determine resection?
- CI to Resection (3)
- SCC vs. Adeno: prevalence, etiology, location/mets
- Tx
1. Chemo/XRT Options (2)
2. Surgeries (4) all of which require _____
3. Endoscopic Option for ____
4. Complications (2) + Treatment - ANSWER - Why so malignant (aka how do they spread?)
Through submucosal lymphatic channels
- Test to Diagnose? Esophagram
- Test to determine resection? CT Chest/Abd
- CI to Resection (3)
1. Invasion of nerves (hoarse RLN, Horners Brachial Plexus, or Phrenic Nerve)
2. Visceral Invasion (airway, vertebra, malignant effusion)
3. +Nodal Base (widely mets)
- SCC vs. Adeno: prevalence, etiology, location/mets
1. Adeno: MCC, lower esophagus associated with GERD/Achalasia, mets to liver
2. SCC: evenly divided, a/w smoking, ETOH, mets to lung
- Tx
1. Chemo/XRT Options (2): 5FU + Cisplatin
2. Surgeries (4) all of which require pyloromyotomy
- Transhiatal: cervical anastamosis, gastric complications
- Ivor Lewis: thoraco anastomosis, thoracic complications
- 3 Hole: 3 incisions neck, thorax, abdomen
- Colonic interposition: 3 anastamosis
3. Endoscopic Option for mucosal disease <2cm
4. Complications (2) + Treatment
- Stricture = dilation
- Fistula to airway = aspiration, palliatve stent
What hormone is NOT released during stress? - ANSWER TSH
Pros/Cons of Burn Care
1. Silvadene
, 2. Silver Nitrate
3. Sulfamylon - ANSWER 1. Silvadene: good for cartilagenous areas (face/ears), causes
leukopenia
2. Silver Nitrate: good for large burns, but very concentrated and quenches cells leading to
hypoNa and hypoCl; also can cause methemoglobinemia
3. Sulfamylon: good for penetrating wounds, but painful and CA inhibitor so causes metabolic
acidosis
Lumbar Hernia
- Boundaries
- Primary vs. Secondary
- Causes
- When to repair? - ANSWER - Boundaries: 12th rib, EOM, iliac crest
- Primary vs. Secondary
1. Primary: true hernia
2. Secondary: denervation injury
- Causes: surgical trauma (kidney operations)
- When to repair?: repair PRIMARY if large and symptomatic
Esophageal Leiomyoma
- MC ____ of the esophagus
- Location within esophageal wall (review layers)
- Location along esophagus
- Dx (2)
- Biopsy?
- When/how to treat? - ANSWER - MC benign tumor of the esophagus
- Location within esophageal wall (review layers)
Occurs in muscularis b/c this is MESECNHYMAL tumor (mucosa --> submucosa --> muscular
propria...NO SEROSA)
- Location along esophagus: lower 2/3 where the SMOOTH MUSCLES are
- Dx (2): Esophagram --> CT to r/o CA
- Biopsy? NEVER; causes fibrotic tissue that makes treatment very hard
