Liver preservation with SCOT 15 solution decreases posttransplantation cholestasis compared with University of Wisconsin solution: a retrospective study.

BACKGROUND: SCOT 15 is a new solution to preserve abdominal organs for transplantation. Its principal characteristic is the use of polyethylene glycol. Herein We report our experience using SCOT 15 compared with the reference University of Wisconsin (UW) solution for hepatic transplantation. METHODS: We compared 2 groups: SCOT 15 (n = 33; 2009-2010) versus UW (n = 34; 2008-2010), which were paired for cold and warm ischemic times, donor ages, and graft weights. Endpoints were biologic tests in the first 2 months after the operation. A linear mixed model was used to evaluate longitudinal changes and influences of each solution. RESULTS: No primary failure was observed. At postoperative day 0, transaminase values were higher in the SCOT 15 than in the UW group: aspartate transaminase: 2,435 ± 399 vs 589 ± 83 IU/L (P < .01); alanine transaminase: ALT: 1,207 ± 191 vs 484 ± 64 IU/L (P < .05), then returned to low levels in both groups. From day 0 to 8, coagulation factors reached normal values; there was no difference between the 2 groups. Total bilirubin decreased similarly in the 2 groups. However, from the second postoperative week (W1) to W8, the SCOT 15 group showed a slow decrease in the mean values of gamma-glutamyltranspeptidase (gGT) from 233 ± 125 to 130 ± 161 IU/L, which were significantly lower than those in the UW group, where the gGT remained around 300 IU/L (P < .01). The End-Stage Liver Disease, Child-Pugh, or United Network for Organ Sharing scores, primary liver diseases, hepatitic C virus status, arterial or biliary complications, and male/female ratio, which was different in the 2 groups, did not statistically influence these results. CONCLUSIONS: The main effect of cold storage of human liver using SCOT 15 compared with UW solution was to decrease cholestasis following transplantation.

An experimental study was carried out in rats to evaluate the outcome of small bowel anastomoses in the presence of peritonitis with and without protection by a polyglactin 910 mesh. One hundred and thirty rats were operated. 1) Thirty small bowel anastomoses were performed in a sterile environment to evaluate the morbidity and mortality due to the surgical procedure itself. All these animals had an uneventful course. 2) Forty anastomoses were performed in a septic environment without protection. Twelve rats died immediately after the procedure. Six rats developed an anastomotic fistula and 22 had an uneventful course. 3) Sixty anastomoses were performed in a septic environment and protected by a polyglactin 910 mesh. Seventeen rats died immediately after the procedure. There were no anastomotic disruptions. Seventeen rats had an uneventful course, and 28 (65%) developed stenosis of the anastomosis. Protection of small bowel anastomoses by a polyglactin 910 mesh appears to effectively prevent disruptions (no anastomotic fistulae or locoregional infections were recorded). However, the mesh is responsible for an intense inflammatory reaction, that often results in intestinal obstruction.

[Surgical emergencies and pseudo-surgical syndromes in the course of acquired immunodeficiency syndromes in adults]. / Urgences chirurgicales et syndromes pseudo-chirurgicaux au cours des syndromes d'immunodéficience acquise de l'adulte.

Numerous abdominal manifestations were noted among 600 patients undergoing treatment at Hospital Laennec for various stages of infection by the acquired immunodeficiency virus. These included violent abdominal pain in 30% of cases, the development of abdominal lymphoma, and occasionally alarming pseudo-surgical syndromes. Diagnosis is difficult, all the more so since authentic emergencies may be aggravated by the immunodeficiency state. 18 cases were collected in 3 years and included 6 cases of acute cholecystitis and 2 of appendicitis. The gangrenous and extensive nature of infection was generally noted and required appropriate antibiotic therapy.

An experimental study was carried out in rats to evaluate the outcome of small bowel anastomoses in the presence of peritonitis with and without protection by a vicryl mesh. One hundred and thirty rats were operated. 1) Thirty small bowel anastomoses were performed in a sterile environment to evaluate the morbidity and mortality due to the surgical procedure itself. All these animals had an uneventful course. 2) Forty anastomoses were done in a septic environment without protection. Twelve rats died immediately after the procedure. Six rats developed an anastomotic fistula and 22 had an uneventful course. 3) Sixty anastomoses were performed in a septic environment and protected by a vicryl mesh. Seventeen rats died immediately after the procedure. There were no anastomotic disruptions. Seventeen rats had an uneventful course, and 28 (46.7%) developed stenosis of the anastomosis. Protection of small bowel anastomoses by a vicryl mesh appears to effectively prevent disruptions and infections (no anastomotic fistulas or locoregional infections were recorded). However, the mesh is responsible for an intense inflammatory reaction, that often results in intestinal obstruction.
