Functional luminal imaging probe geometric and histomorphologic analysis of abdominal wall wound induced by different trocars in pigs.

Background: This study aimed to investigate wound geometry and tissue damage caused by several different trocar types using a quantitative functional luminal imaging probe (FLIP) geometric profile and histomorphologic analysis.

Methods: Four pigs were used in this study. After general anesthesia, six different trocars were randomly inserted at preselected locations in the porcine abdominal wall.

Analysis of abdominal wounds made by surgical trocars using functional luminal imaging probe (FLIP) technology.

The aim was to use a novel functional luminal imaging probe for evaluation of wound defects and tissue damage resulting from the use of trocars. Following general anesthesia of 4 adult pigs, 6 different trocars were randomly inserted at preselected locations in the porcine abdominal wall. The functional luminal imaging probe was used to profile the trocar holes during bag distension from 8 axial cross-sectional area measurements.

Idiopathic cholangiopathy in a biliary cast syndrome necessitating liver transplantation following head trauma.

The development of total biliary casts is very unusual, especially in patients who have not undergone liver transplantation. The aetiology of these casts is uncertain but several factors are believed to play a role, including periods of fasting, haemolysis, cholangitis and recent surgery. Resultant bile stasis and/or gallbladder hypocontractility promote sludge and subsequent stone formation.
