Keyhole Versus Sugarbaker Mesh Configuration in Parastomal Hernia Repair: A Systematic Review and Meta-analysis.

Background: Parastomal hernia repairs (PHRs) are often complex and challenging, even for experienced abdominal wall surgeons. Although the ideal therapeutic option in the setting of a parastomal hernia is to restore intestinal continuity, this is often not feasible, and numerous techniques have been described for PHR. Current guidelines recommend using mesh for elective PHR, but there is a scarcity of evidence comparing different PHR techniques.

Are the virtual lines created with the EnSite electroanatomical mapping system really continuous?

Background: EnSiteNavx electroanatomic mapping system is widely used in radiofrequency (RF) atrial fibrillation ablation, helping the creation of linear lesions. However, the correspondence of the virtual line created by EnSite with the pathological lesion has not yet been evaluated.

Objective: to assess the continuousness of Ensite-guided virtual lines in a swine model.

Impact of prophylactic corticosteroids on systemic inflammation after extensive atrial ablation in pigs.

Aims: Prophylactic corticosteroids have been reported to attenuate the increase in C-reactive protein (CRP) and the incidence of atrial fibrillation (AF) both after heart surgery and AF ablation. We tested the impact of a single prophylactic corticosteroid dose on ultrasensitive CRP 24 h and 14 days after extensive linear atrial ablation (8 mm or 3.5 irrigated tip) guided by electroanatomical mapping (NavX) in pigs with normal hearts.

Impact of corticosteroids on late growth of radiofrequency lesions in infant pigs: histopathological and electroanatomical findings.

Aims: Corticosteroids attenuate late growth of radiofrequency (RF) lesions in the thigh muscle of infant rats. We sought to assess the impact of these drugs on the late growth of RF lesions in immature swine myocardium and to determine the electroanatomical mapping (EAM) characteristics of these lesions.

Methods And Results: Radiofrequency (60°C; 60 s) lesions were created in the right atrium (n = 2) and ventricle (n = 2) of 14 piglets (age 65 days; weight 5 kg) and 3 adults.

Effects of the corticosteroids in the lesions by radiofrequency on rats' thigh in different age groups.

Background: The corticosteroids limit the late growth of the lesions by radiofrequency (RF) on the rats' infants' thighs, but the effects on the pubescent and adult rats are unknown.

Objective: Evaluate the effects of the corticosteroids in the healing of the lesions by RF on the rats' thighs muscles in different age groups.

Methods: Ablation was performed on the thigh muscle of 30 rats (1 lesion per animal): infants (30 days old, weight 73 g, n = 10), pubescents (60 days old, weight 230 g, n = 10) and 10 adults (90 days old, 310 g, n = 10), subdivided in control and treated groups, that received Hydrocortisone (10 mg/kg IM post-RF) and Betametasone (3.

Effects of corticosteroid therapy on the long-term outcome of radiofrequency lesions in the Swine caval veins.

Background: We explored the angiographic and pathological effects of corticosteroids on the long-term outcome of radiofrequency (RF) ablation lesions in the swine caval veins.

Methods: Under fluoroscopy guidance, a single linear RF lesion (4-mm tip, 60 degrees C, 180 seconds) was created in each vena cava (from +/-2 cm into the vein to the venoatrial junction) of 20 anesthetized minipigs (35+/- 2 kg). Three groups were studied: acute (n = 4), killed 1 hour after RF; control (n = 8), sacrificed 83+/- 1 days after RF; and pigs (n = 8) receiving hydrocortisone (400 mg i.

Acute and chronic effects of extensive radiofrequency lesions in the canine caval veins: implications for ablation of atrial arrhythmias.

Background: Although radiofrequency (RF) ablation within the caval veins has been increasingly used to treat a variety of atrial tachyarrhythmias, the consequences of RF ablation in the caval veins are unknown. We explored the acute and chronic angiographic and pathological effects of extensive RF ablation in the caval veins.

Methods: Under fluoroscopy guidance, conventional (4 mm tip, 60 degrees C, 60 seconds) RF applications (n = 6-7) were delivered in each vena cava (from +/-2 cm into the vein to the veno-atrial junction) of 15 dogs (10 +/- 3 kg).

Surgical treatment of anal stenosis: assessment of 77 anoplasties.

Purpose: Anal stenosis is a rare, incapacitating, and challenging condition, occurring mainly after hemorrhoidectomy, for which several surgical techniques have been devised. The purpose of this study was to describe early and late (1 year) results of 77 anoplasty operations performed in the Colorectal Unit of our institution.

Methods: From 1977 to 2002, 77 patients with moderate to severe anal stenosis underwent surgery using two sliding graft techniques: 58 underwent Sarner's operation and 19 underwent Musiari's technique.

Umbilical mass as the sole presenting symptom of pancreatic cancer: a case report.

Umbilical nodes are rare. The metastatic involvement of the region was first described in 1846. Sister Mary Joseph was the first observer to establish the correlation between carcinomas and umbilical nodes.
