Detailed Answer:
Hello,
Thank you for using HCM. I understand your concern.
Your mother may have developed an
umbilical hernia (the intestine or other tissues bulge through this weak spot around the belly button,
umbilicus), which has become infected over time. The infection has perforated the walls of the intestine, making possible the feces and pus, to come out from the navel.
In these conditions the surgical reparation is inevitable and is the only way to fix this problem definitively. The
abdominal wall defect should be repaired and should be reset the normal passage of the feces through the intestine. This should be done as soon as possible. However, being in such a condition for 6-weeks, 4 more days don't make any difference. Meanwhile she has to be under iv antibiotics and fluids. As the infection may disperse (as you say, may cause
peritonitis), and may affect all her general health, it would be better that these 4 days she would be hospitalized and under strict medical monitoring.
Hope this is helpful.
