LIVER BIOPSY: IMPORTANCE OF SPECIMEN SIZE IN THE DIAGNOSIS AND STAGING OF CHRONIC VIRAL HEPATITIS
Liver biopsy is the gold standard method for the grading and staging of chronic viral hepatitis, but optimal biopsy specimen size remains controversial. The aim of this study was to evaluate the quality of liver specimen (number of portal tracts) and to evaluate the impact of the number of portal tracts in the staging of chronic hepatitis. Material and Methods: 468 liver biopsies from consecutive patients with hepatitis C virus and hepatitis B virus infection from 2009 to 2010 were evaluated. Results: The length of fragment was less than 10 mm in 43 cases (9.3%), between 10 and 14 mm in 114 (24.3%), and ≥ 15 mm in 311 (64.4%); of these, in 39 (8.3%) cases were ≥ 20 mm. The mean representation of portal tracts was 17.6 ± 2.1 (5-40); in specimens ≥ 15 mm the mean portal tract was 13.5 ± 4.7 and in cases ≤ 15 mm was 11.4 ± 5.0 (p = 0.002). Cases with less than 11 portal tracts were associated with F3, and cases with 11 or more portal tracts with F2 (p = 0.001). Conclusion: this study demonstrated the good quality of liver biopsy and a relationship between the macroscopic size of the fragment and the number of portal tracts
A feasibility study with survival in swine model
Transrectal access still has some unsolved issues such as spatial orientation,
infection, access and site closure. This study presents a simple technique to
perform transcolonic access with survival in a swine model series. A new
technique for NOTES perirectal access to perform retroperitoneoscopy,
peritoneoscopy, liver and lymphnode biopsies was performed in 6 pigs, using
Totally NOTES technique. The specimens were extracted transanally. The
flexible endoscope was inserted through a posterior transmural incision and
the retrorectal space. Cultures of bacteria were documented for the
retroperitoneal space and intra abdominal cavity after 14 days. Rectal site
was closed using non-absorbable sutures. There was no bowel cleansing, nor
preoperative fasting. The procedures were performed in 6 pigs through
transcolonic natural orifice access using available endoscopic flexible
instruments. All animals survived 14 days without complications, and cultures
were negative. Histopathologic examination of the rectal closure site showed
adequate healing of suture line and no micro abscesses. The results of
feasibility and safety of experimental Transcolonic NOTES potentially brings
new frontiers and future wider applications for minimally invasive surgery.
The treatment of colorectal, abdominal and retroperitoneal diseases through a
flexible Perirectal NOTES Access (PNA) is a promising new approach
