Patient Comments (1)
in Palmer, AK |
Removed gall bladder. Surgery seemed to go ok. Went home next day, feeling pretty good. Two days later, crippling pain -- he nicked the main bile duct. Different surgeon fixed it on emergency basis, but spent 10 days in the hospital. Never saw/heard from Zwaicher. Difficult recovery with ongoing pain and other symptoms, but Zwaicher treated me like a complainer. Tried to talk with him, but he was dismissive and arrogant; spent less than 5 minutes with me. Would NEVER go back.
