Non Hepatic Surgery In Cirrhotics


MCQ: Models Predicting Outcome of Non-Liver Surgeries in Cirrhotic Patients
Question: Which of the following is not a model predicting the outcome of non-liver surgeries in cirrhotic patients?
a) MELD Na
b) ADOPT-LC
c) VOCAL-Penn
d) CTP
e) none
Correct Answer: e) none
Explanation:
All the listed models are used to predict outcomes in cirrhotic patients undergoing non-liver surgeries:
- MELD Na: Modified MELD score that includes sodium levels to predict surgical outcomes.
- ADOPT-LC: A model that incorporates CTP score, age, Charlson comorbidity index, and duration of anesthesia.
- VOCAL-Penn: A comprehensive model that includes the Mayo risk score, emergency status, and surgery-specific categories to predict postoperative outcomes.
- CTP (Child-Turcotte-Pugh): A widely used score to assess the severity of liver disease and predict surgical risks.
Cholecystectomy in Cirrhotics: Key Points
- Increased Risk of Gallstones:
- Cirrhotic patients have twice the incidence of gallstones compared to the general population due to:
- Increased intravascular hemolysis
- Decreased gallbladder motility and emptying
- Cirrhotic patients have twice the incidence of gallstones compared to the general population due to:
- Historical Context:
- In the 1980s, open cholecystectomy in cirrhotic patients had high morbidity (35%) and mortality (25%) rates, primarily due to blood loss, sepsis, and liver failure.
- Laparoscopic cholecystectomy was initially avoided due to fears of increased bleeding and liver failure but is now shown to have favorable outcomes in CTP class A and B patients.
- Laparoscopic vs. Open Cholecystectomy:
- Laparoscopic cholecystectomy offers:
- Improved visualization
- Less operative blood loss
- Shorter operative time
- Decreased length of hospital stay
- Studies show higher morbidity (21% vs. 8%), intraoperative bleeding (26% vs. 3%), and open conversion rates (7% vs. 4%) in cirrhotics compared to non-cirrhotics but no difference in mortality.
- Meta-analysis: Laparoscopic approach is associated with reduced complication rates and shorter hospital stay compared to the open approach.
- Laparoscopic cholecystectomy offers:
- Technical Considerations:
- Umbilical port placement should avoid venous collaterals and the umbilical vein.
- Transillumination or preoperative CT may help avoid vascular injury during trocar placement.
- Instruments like Harmonic Scalpel and LigaSure are useful to control bleeding.
- Subtotal cholecystectomy may be necessary in cases with large pericholecystic venous collaterals.
- Direct visualization during trocar removal ensures adequate hemostasis.
- Conversion to open surgery should be considered if anatomy is unclear.
- Advanced Cirrhosis (CTP Class C):
- Cholecystectomy is associated with very poor outcomes in advanced cirrhosis.
- Alternative interventions:
- Percutaneous cholecystostomy
- Endoscopically placed cystic duct stent (less common and limited data)
- Predictors of Outcomes:
- Both CTP and MELD scores are valuable for predicting postoperative morbidity and mortality.
- CTP A and B patients can typically undergo surgery with acceptable outcomes.
- MELD score cutoff varies, but laparoscopic cholecystectomy is generally safe for patients with MELD < 15.
- High-Risk Patients:
- In CTP class C or high MELD score patients, surgery should be deferred if possible, and alternative therapies should be considered as a bridge to surgery when liver function improves.
MCQ: Laparoscopic Cholecystectomy in Cirrhotics
Question: Which of the following is not true about laparoscopic cholecystectomy in cirrhotics?
a) Can be performed in CTP A and B and with MELD < 15
b) Recommended in CTP C symptomatic cholelithiasis in expert centers
c) Umbilical port introduction after other ports
d) Subtotal cholecystectomy - a valid option
Correct Answer: b) Recommended in CTP C symptomatic cholelithiasis in expert centers
Explanation:
- Option a is correct: Laparoscopic cholecystectomy can indeed be performed in patients with CTP A and B and MELD < 15 with acceptable outcomes.
- Option c is correct: Introducing the umbilical port after other ports helps avoid venous collaterals and the umbilical vein, which is a recommended approach in cirrhotics.
- Option d is correct: Subtotal cholecystectomy is a valid option in difficult cases, especially when there are large pericholecystic venous collaterals.
- Option b is not true: Laparoscopic cholecystectomy is not recommended in CTP C patients due to very poor outcomes. Alternative procedures like percutaneous cholecystostomy are preferred.
Thus, option b is the false statement.
Herniorrhaphy in Cirrhotics: Key Points
- Incidence and Pathogenesis:
- Umbilical hernias occur in up to 20% of cirrhotic patients.
- Causes include:
- Increased intra-abdominal pressure from ascites.
- Poor nutritional status leading to decreased abdominal muscle mass and fascial strength.
- Umbilical vein dilation resulting in enlargement of the preexisting supraumbilical fascial opening.
- Risks and Complications:
- In cirrhotic patients, umbilical hernias pose unique risks:
- Skin ulceration over the hernia can lead to:
- Leakage of ascites
- Sac rupture
- Bacterial peritonitis
- Evisceration
- Flood syndrome: Spontaneous umbilical rupture and ascites leak, associated with up to 60% perioperative mortality.
- Skin ulceration over the hernia can lead to:
- In cirrhotic patients, umbilical hernias pose unique risks:
- Surgical Outcomes:
- Historically, high mortality rates led to the recommendation against repairing uncomplicated hernias in cirrhotics.
- Recent data show improved outcomes for elective UHR (Umbilical Hernia Repair), even in cirrhotics with end-stage liver disease.
- Marsman et al. study: Elective UHR group had no hepatic decompensation or perioperative deaths, while the conservative management group had significantly higher complication rates, including emergency repairs and perioperative deaths.
- Elective vs. Emergent Repair:
- Elective UHR is associated with outcomes similar to those in non-cirrhotics, whereas emergent UHR leads to significantly worse outcomes in cirrhotic patients.
- Perioperative management: TIPS may be considered to reduce refractory ascites before UHR, although specific studies on its efficacy for reducing complications of UHR are lacking.
- Use of Mesh:
- The use of nonabsorbable mesh in cirrhotic patients with umbilical hernias is debated, but recent evidence suggests it can be used successfully, even in the presence of ascites.
- Randomized study (2010): Mesh repair led to a lower recurrence rate compared to suture repair (3% vs. 14%), despite a non-significant increase in surgical site infections.
- Inguinal Hernia Repair:
- Outcomes after elective inguinal hernia repair in cirrhotic patients are similar to those in non-cirrhotics.
- Emergent repair of an incarcerated or strangulated inguinal hernia in cirrhotics results in significantly worse outcomes.
- Mesh use in inguinal hernia repair is generally safe, with manageable local wound complications.
- Current Recommendations:
- Elective hernia repair (umbilical or inguinal) is advisable in cirrhotic patients, provided they are well-compensated, and ascites is controlled, to avoid complications associated with emergent repairs.
Herniorrhaphy in Cirrhotics: Key Points
- Umbilical Hernias: Occur in up to 20% of cirrhotic patients, caused by ascites, poor nutrition, and umbilical vein dilation.
- Risks:
- Skin ulceration can lead to ascites leakage, rupture, and bacterial peritonitis.
- Flood syndrome (spontaneous rupture) has up to 60% mortality.
- Surgical Outcomes:
- Elective UHR has better outcomes than emergent repair.
- Mesh repair reduces hernia recurrence; infections are manageable.
- Inguinal Hernia:
- Elective repair is safe; outcomes worsen significantly with emergent repair.
- Recommendation:
- Elective hernia repair is advised in well-compensated cirrhotics [CTP A and B] with controlled ascites.
MCQ: Complications of Umbilical Hernia Repair in Cirrhotic Patients with Ascites
Question: Possible complications of umbilical hernia repair in a cirrhotic patient with marked ascites include all of the following EXCEPT:
a) Hepatic encephalopathy
b) Leakage of ascitic fluid
c) Necrosis of the abdominal wall
d) Variceal bleeding
Correct Answer: a) Hepatic encephalopathy
Explanation:
- Leakage of ascitic fluid: Common complication that increases the risk of wound infection.
- Necrosis of the abdominal wall: Can occur due to pressure on the incision and reforming ascites.
- Variceal bleeding: May result from the interruption of collateral veins during surgery.
- Hepatic encephalopathy: While possible, it is uncommon unless it occurs secondary to massive variceal bleeding.
Thus, the correct answer is a) Hepatic encephalopathy, as it is not a direct or common complication of umbilical hernia repair in cirrhotic patients with ascites.
