Abstract:
Once upon a time, a bariatric general surgeon palpated a liver of normal consistency as he was repairing an incisional hernia, but momentarily recalled the pathology of a biopsy taken at the time of the patient’s bariatric surgery - which had shown liver fibrosis. Very surprised, but staying professional, he didn’t say a word about his finding instead asking for the scalpel to perform a second open biopsy sending the specimen to Pathology as a routine liver biopsy before completing the hernia repair. A week later the surgeon received the Pathology report of normal liver tissue taken at the time of open incisional herniorrhaphy. Surprised, worried, but happy the surgeon checked with the pathologist about differences between the past and present diagnoses of the two liver biopsies. That ‘event’ was a landmark of an unbelievable journey. Years before in February 1984, my esteemed close colleague, Picard Marceau, and I decided to adopt Scopinaro’s Bilio-Pancreatic diversion (BPD) as our major bariatric technique. Needless to say: the disastrous long-term outcomes of jejuno-ileal bypass biased recognition of the value of this new bypass. This prompted us to initiate a prospective systematic follow-up of our patient’s livers and nutritional status. It was, indeed, our duty to perform liver biopsies whenever possible. For quality assurance and ‘blinded’ evaluations we accepted the offer of collaboration with our colleague John G. Kral and the renowned Liver Pathologist Swan N. Thung. Seven cases of bridging fibrosis exhibited normal histopathology upon re-biopsy several years after BPD.
