Liver biopsy interpretation for causes of late liver allograft dysfunction

Abstract Evaluation of needle biopsies and extensive clinicopathological correlation play an important role in the determination of liver allograft dysfunction occurring more than 1 year after transplantation. Interpretation of these biopsies can be quite difficult because of the high incidence of recurrent diseases that show histopathological, clinical, and serological features that overlap with each other and with rejection. Also, more than one insult can contribute to allograft injury. In an attempt to enable centers to compare and pool results, improve therapy, and better understand pathophysiological disease mechanisms, the Banff Working Group on Liver Allograft Pathology herein proposes a set of consensus criteria for the most common and problematic causes of late liver allograft dysfunction, including late-onset acute and chronic rejection, recurrent and new-onset viral and autoimmune hepatitis, biliary strictures, and recurrent primary biliary cirrhosis and primary sclerosing cholangitis. A discussion of differential diagnosis is also presented

Laparoscopic versus open ileo-colonic resection in Crohn's disease: short- and long-term results from a prospective longitudinal study

Possible relations between surgical approaches, frequency, and severity of Crohn's disease recurrence after ileo-colonic resection is unknown. We aimed to assess perioperative outcomes and postsurgical complications of laparoscopic versus standard open surgery and to detect differences between the two groups in endoscopical recurrence and patients' satisfaction. Twenty-eight consecutive patients undergoing elective ileo-colonic resection by either laparoscopic approach (n = 15) or conventional open surgery (n = 13) were prospectively enrolled. No mortality or major intraoperative complications were observed in both groups. Significant differences between groups were the median operating time found shorter in the open group than in the laparoscopic group (p = 0.003), the higher dosage of pain killers needed in the open group (p = 0.05), the passage of flatus and\or stool after surgery found faster in group A (p = 0.004) and the shorter recovery period in the laparoscopic group (p = 0.007). Colonoscopy was performed in 27 patients. The frequency and pattern of recurrence did not differ between the two groups (p = 0.63). Patients' satisfaction was significantly in favor of laparoscopy. Present findings support the feasibility and advantages in the short-term of laparoscopic ileo-colonic resection in patients with Crohn's disease. No differences were observed in terms of frequency, time of onset, and severity of recurrence in a 1-year follow-up
