Cholangiocarcinoma: Dealing with husband's long stay in ICU

My husband diagnosed 12/22/24. Had the following surgery on 03/03/25:

1) Diagnostic laparoscopy
2) Exploratory laparotomy
3) Cholecystectomy
4) Extended R hepatectomy
5) En-bloc resection of extrahepatic biliary tree
6) En-bloc portal vein resection and reconstruction
7) En-bloc porta-hepatis lymphadenectomy
8) Roux-en-Y hepaticojejunostomy reconstruction
9) Excision of small bowel nodule

Surgery was a success with negative margins. He is still inpatient and has been in ICU since 03/30/25. Can anyone share similar experiences??
