Impregnation of the absorbable hydrophilic prosthesis PGA-TMC with cefazolin prevents the infection of the prosthesis placed in infected localization. Therefore, we think this option should be considered as a new and useful alternative in case of contaminated and dirty surgical fields or when a replacement of the prosthesis is required.

Fibrin glue reduces both the quantity and consistency of adhesions, even in the case of polypropylene meshes.

Objective: we want to present our experience about surgical pathology of Meckel's diverticulum by means of a retrospective study.Material and methods: we report a group of patients of our Department of General and Abdominal Surgery and Paediatric Surgery of our Hospital with Meckel's diverticulum since January of 1997 to January of 2010. We report the clinical presentation, complementary test, interventions, and the postoperative follow up.Results: 45 patients were operated in total, 33 of them in emergency surgery under the clinical form of acute abdominal pain; and the others 12 in programmed surgery, these cases came up more frequently like a clinical manifestations of latent abdominal pain, rectal bleeding and anaemia. The complementary tests were so varied; abdominal ultrasounds were used in 63% of emergency cases and the 40% of programmed cases, in these patients, gammagraphy with Tc99 was the second test in frequency. Laparoscopy was used in 10 cases (22%). The main surgery technique used was diverticulectomy (82%).Conclusions: the presence of Meckel's diverticulum has to be clinically suspected in all patients with abdominal pain of unknown aetiology. Access to the abdominal cavity using routine laparoscopy provides essential information on the diagnosis and for the treatment.

AIMTo evaluate the effectiveness of human fibrinogen-thrombin collagen patch (TachoSil®) in the reinforcement of high-risk colon anastomoses.METHODSA quasi-experimental study was conducted in Wistar rats (n = 56) that all underwent high-risk anastomoses (anastomosis with only two sutures) after colectomies. The rats were divided into two randomized groups: Control group (24 rats) and treatment group (24 rats). In the treatment group, high-risk anastomosis was reinforced with TachoSil® (a piece of TachoSil® was applied over this high-risk anastomosis, covering the gap). Leak incidence, overall survival, intra-abdominal adhesions, and histologic healing of anastomoses were analyzed. Survivors were divided into two subgroups and euthanized at 15 and 30 d after intervention in order to analyze the adhesions and histologic changes.RESULTSOverall survival was 71.4% and 57.14% in the TachoSil® group and control group, respectively (P = 0.29); four rats died from other causes and six rats in the treatment group and 10 in the control group experienced colonic leakage (P > 0.05). The intra-abdominal adhesion score was similar in both groups, with no differences between subgroups. We found non-significant differences in the healing process according to the histologic score used in both groups (P = 0.066).CONCLUSIONIn our study, the use of TachoSil® was associated with a non-statistically significant reduction in the rate of leakage in high-risk anastomoses. TachoSil® has been shown to be a safe product because it does not affect the histologic healing process or increase intra-abdominal adhesions.
