Complications in Immunosuppressive Therapy of Liver Transplant Recipients

2011

BACKGROUND: In liver transplantation (LT), modern immunosuppressive protocol is focused on early corticosteroid (CS) weaning. The aim of the study was to investigate all early transplant-related complications using Clavien grading system, in order to identify a significant relation in two homogenous groups of consecutive liver transplanted patients, only different for steroid avoidance in immunosuppressive regimen. MATERIALS AND METHODS: One group was treated with a tacrolimus-based CS-free immunosuppressive protocol, the other one underwent tacrolimus plus low dose CS therapy. The preoperative continuous variables analyzed were age, gender, model for end-stage liver disease (MELD) score, a…

Freestyle pedicled perforator flaps: safety, prevention of complications, and management based on 85 consecutive cases.

2011

Background: Despite the widespread use of free perforator flaps, pedicled perforator flaps seem not to be as widely accepted, probably because of the fear of vascular complications caused by transfer of a flap attached only by its vascular pedicle, prone to shearing, kinking, and trauma. In this article, the authors report on their experience with 85 consecutive cases, focusing on incidence, prevention, and management of complications. Methods: Eighty-five consecutive cases were treated over 6 years at the Plastic and Reconstructive Surgery Department of the University of Palermo for defects of different causes that were reconstructed with a freestyle pedicled perforator flap, in every regi…

Prevention of ischemic-type biliary lesions by arterial back-table pressure perfusion

2003

Abstract Ischemic-type biliary lesions (ITBLs) lead to considerable morbidity after orthotopic liver transplantation (OLT). The exact pathogenesis is unknown. We tested the hypothesis that insufficient perfusion of biliary arterial vessels might be responsible for ITBLs. This could be prevented by improved perfusion techniques. Since February 2000, we performed a controlled study using arterial back-table pressure perfusion (AP) to achieve reliable perfusion of the biliary-tract capillary system, which may be impaired by the high viscosity of University of Wisconsin solution. We retrospectively analyzed 190 OLTs performed between September 1997 and July 2002 with regard to ITBLs. One hundre…

Analysis of interleukin-6 and interleukin-8 in lung transplantation: correlation with nitric oxide administration.

2008

Introduction and Objectives. Primary graft dysfunction (PGD) following lung transplantation (LT) is associated with an activation of the inflammatory cascade and release of cytokines. Inhaled nitric oxide (iNO) provides specific pulmonary vasodilatation and improves oxygenation. Our objective was to verify whether administering iNO to LT patients modified the blood and bronchoalveolar lavage (BAL) interleukin (IL)-6 and -8 levels in the event of PGD. Materials and Methods. Thirty-two LT patients were randomized to the iNO treatment or the control group. Patients in the first group were given 10 ppm of iNO from the start of LT until 48 hours afterward. BAL and peripheral arterial blood sampl…

Subtemporal Keyhole Approach to the Suprasellar and Petroclival Region: Microanatomic Considerations and Clinical Application

1997

OBJECTIVE: To minimize surgical invasiveness, the keyhole concept is applied to the subtemporal approach. METHODS: Anatomic features were studied in 14 sides of adult cadaver heads, and the technique was used in 162 interventions. Although most of the lesions treated were 3 cm in size or smaller, larger lesions were also treated using this technique. In some cases, if needed, an endoscope-assisted microsurgical technique was used. RESULTS: The cadaveric study provided intimate experience with the microsurgical anatomy of the approach. The 162 consecutive patients who were operated on harbored various types of lesions; the most recent 43 consecutive interventions were investigated in detail.…

Laparoscopic-assisted Retropubic Midurethral Sling Placement: A Technique to Avoid Major Complications

2015

Abstract Study Objective To describe a technique for the safe placement of retropubic midurethral slings in patients undergoing concomitant laparoscopic surgery in order to avoid major complications associated with this procedure such as bladder perforation and retropubic hematomas. Design Step-by-step video demonstration of the technique. Setting A university tertiary care hospital. Patients Patients with an indication for retropubic midurethral sling placement because of recurrent stress urinary incontinence, intrinsic sphincter deficiency, or severe pelvic organ prolapse in whom a concomitant laparoscopic surgery has to be performed for other medical conditions. Intervention Laparoscopic…

Robotic treatment of colorectal endometriosis: technique, feasibility and short-term results

2012

background: Deep infiltrating endometriosis (DIE) is a complex disease that impairs the quality of life and the fertility of women. Since a medical approach is often insufficient, a minimally invasive approach is considered the gold standard for complete disease excision. Roboticassisted surgery is a revolutionary approach, with several advantages compared with traditional laparoscopic surgery. methods: From March 2010 to May 2011, we performed 22 consecutive robotic-assisted complete laparoscopic excisions of DIE endometriosis with colorectal involvement. All clinical data were collected by our team and all patients were interviewed preoperatively and 3 and 6 months post-operatively and ye…

Inguinal hernioplasty in patients with cirrhosis and ascites: what preventive measures are needed for a safe procedure?

2019

Inguinal hernioplasty in patients with LC and ascites has been long discouraged for the incidence of postoperative complications. The aim is to evaluate the appropriateness of this elective surgical procedure in patients with LC and ascites.Thirty consecutive LC patients with ascites and affected by inguinal hernia (LC group), who underwent elective open inguinal hernioplasty with mesh placement, have been matched with the same number of patients non-LC (non-LC group) who underwent the same surgical procedure in the same period of time. All patients in LC group received a careful hepatological assessment and were classified according to the etiology of LC and to the Child's class. Patients …

Cirrhosis of mixed etiology (hepatitis C virus and alcohol): Posttransplantation outcome-Comparison with hepatitis C virus-related cirrhosis and alco…

2008

Hepatitis C virus (HCV)-related liver disease is enhanced by alcohol consumption. Of HCV-related liver transplantation (LT) recipients, 25% have a history of alcohol intake. The purpose of this research was to determine whether LT outcome differs between patients with cirrhosis of mixed etiology compared to HCV or alcohol alone. Of 494 LT (1997-2001), recipient/donor features, post-LT histological, metabolic complications [hypertension, diabetes-diabetes mellitus (DM)], and de novo tumors were compared in 3 groups [HCV-related cirrhosis = 170 (HCV group), alcohol-related cirrhosis (alcohol group) = 107, and cirrhosis of mixed etiology (mixed group) = 60]. Protocol biopsies were done in HCV …
