Q

Treatment for retroperitoneal sarcoma:

A

Complete en bloc resection of the tumor with any involved adjacent organs (primary treatment); if invading inferior vena cava (IVC), the IVC can be excised and bypassed in the absence of sufficient collaterals. There used to be no role for radiation secondary to visceral toxicity, but with the advent of better radiation some institutions are giving radiation either pre- or postoperatively. If inoperable, symptomatic disease can consider chemotherapy with radiation.

Q

Operative management for a patient with a right mesocolic (paraduodenal) hernia:

A

Incise the lateral peritoneal reflections along the right colon with reflection of the right colon and cecum to the left without opening the hernia neck (could injure superior mesenteric vessels).

133

A

Transabdominal preperitoneal (TAPP) repair

135
Q

What is the Circle of Death in regards to hernia repair?

A

Also known as the corona mortis, a vascular ring formed by the joining of an aberrant artery with the normal obturator artery arising from a branch of the internal iliac artery; during a laparoscopic hernia repair this vessel can be torn from both ends and bleed profusely

139
Q

How do you calculate the SAAG?

A

Serum albumin concentration – ascites albumin concentration

140
Q

What nerve runs anterior to the spermatic cord in the inguinal canal and branches at the superficial inguinal ring?

A

Ilioinguinal nerve

141
Q

Name the tension-free inguinal hernia repair: a repair that uses a bilayered device with 3 polypropylene components (underlay circular patch, connector, and onlay patch) covers the posterior inguinal floor.

A

Prolene hernia system (PHS) repair

142
Q

How do you make the diagnosis of retroperitoneal fibrosis?

A

Patient’s history and IV urography demonstrating medial deviation of the ureters and hydronephrosis and hydroureter associated with delayed excretion

143
Q

Treatment for a retroperitoneal abscess:

A

Antibiotics and CT-guided drainage; if not amenable to percutaneous drainage or if fails to resolve with percutaneous drainage, then perform operative drainage through a retroperitoneal approach.

144
Q

What are the various methods through which a femoral hernia can be repaired?

A

Cooper ligament repair, via a preperitoneal approach, or a laparoscopic approach

145
Q

What nerves are most commonly affected during laparoscopic hernia repair?

A

Lateral femoral cutaneous and genitofemoral nerves

146
Q

If you have to give preoperative antibiotics before a hernia repair, what antibiotics do you give? How about a penicillin allergic patient?

A

Cefazolin, 1 to 2 g IV 30 to 60 minutes before incision if penicillin allergic, give clindamycin 600 mg IV or vancomycin 1 g IV
