Elective Umbilical Hernia Repair in Patients With Cirrhosis

Summary

Liver cirrhosis is a frequent and severe chronic disease. About 20 % of patients with liver cirrhosis develop umbilical hernias. In comparison, the prevalence in the general population is around 2 %. Patients with liver cirrhosis are often neglected and are not offered equal surgical treatments compared with other patient groups with chronic diseases due to fear of postoperative complications. The current literature is sparse, and many questions remain to be answered, such as timing of repair, risk profile, preoperative staging of the liver disease, possible optimization before surgery, repair technique, and postoperative care. Moreover, nationwide data are lacking.

The management of umbilical hernias in patients with cirrhosis is debated. Recently, European Hernia Society published guidelines stating that elective hernia repair may be safe, and that emergency repair is associated with a high rate of morbidity and mortality. Nonetheless, surgeons remain reluctant to perform elective surgery on these patients due to fear of complications and mortality. The evidence supporting the guidelines is sparse and consists of small, low quality studies. One of the major concerns is that the existing studies failed to use clear and well-described definitions of the underlying severity of the liver disease. The rate of emergency repair may be much higher in patients with liver cirrhosis compared with the general population but there is no data available. The rate of emergency vs elective repair in patients with liver cirrhosis in Denmark is unknown, as well as the rate of reoperation for complications and readmission. Finally, we hypothesize that these patients may benefit from a more proactive approach with early diagnosis of their umbilical hernia by screening, preoperative optimization, and early elective hernia repair, but the effect of this hypothesis needs further evaluation.

Conditions

• Cirrhosis, Umbilical Hernia

Interventions

OTHER

Screening

Screening: All health professionals at the hospitals will participate in the screening of umbilical hernia. The screening will be done in the outpatient clinic, the Emergency Department and at the hospital wards.

PROCEDURE

Preoperative optimization

Ascites will be drained using percutaneous drainage or PleurX. Diuretics be used to control ascites preoperative. Haemoglobin \< 5 mmol/L indicates the need for red blood cell concentrates using two dosage SAG-M (350-400 mL of red blood cell concentrates in each dose) will be done. Thrombocytopenia \< 150 10\^9/L will be treated with a TPO-analog using avatrombopag 40-60 mg dispensed as an intravenous fluid. Culture verified infection will be treated with specific antibiotics depending on the blood culture. International Normalized Ratio \> 1.7 will be treated with either phytomenadion, Octaplex or fresh frozen plasma depending on the INR.

PROCEDURE

Umbilical hernia repair

A curved incision placed superiorly or inferiorly around the umbilicus. The umbilicus proper is retained in the skin flap. The blunt dissection is made to the hernia sac. The neck of the herniated sac is then dissected from adjacent tissues by a combination of blunt and sharp dissection. The edges of the fascial defect are measured and the fascial defect is closed with a non-absorbable running suture 2-0. A fitted lightweight polypropylene mesh is placed in an onlay fashion and fixed with 4-8 single non-absorbable sutures in the corners and at the midline, with a mesh overlap of at least 4 cm. The umbilicus is re-inserted with a single knot absorbable suture 3-0. Hemostasis is ensured. Skin closure is performed with Nylon suture 3-0. 20 ml bupivacaine 0.5% is injected to the fascia for early pain control.
