Superiority of Single-Antigen Bead Study in Donor-Specific Antibodies: Determination in Highly Sensitized Patients.

Objectives: The presence of donor-specific antibodies against HLA before kidney transplant has been variably associated with decreased long-term graft survival. Data on the association between pretransplant donor-specific antibodies and rejection and cause of graft failure in recipients of donor kidneys are scarce.

Materials And Methods: For this study of HLA antibody levels, we analyzed serum samples from 76 patients (48 women and 28 men) who were prepared for kidney transplant at the Baskent University İstanbul Hospital between 2017 and 2022.

Use of Eculizumab in Pediatric Patients with Late Antibody-Mediated Rejection After Kidney Transplantation.

Late antibody-mediated rejection triggered by donor-specific antibodies is a leading cause of kidney allograft failure. Effective treatment options for late antibody-mediated rejection are limited in renal transplant recipients. Here, we report 2 pediatric cases of severe late antibody-mediated rejection resistant to conventional immunosuppressive therapy who were successfully treated with eculizumab.

Clinical Outcomes of Liver Transplantation for Patients Over 60 Years Old: A Single-Center Experience.

Objectives: Although advanced age is no longer considered an absolute contraindication for liver transplant, transplant in elderly patients with comorbid diseases remains debatable because of high risks with surgery. Here, we report patient outcomes in this population.

Materials And Methods: We retrospectively reviewed medical records of 276 liver transplant recipients, grouped by age.

Concurrence of rectocoele and anal incontinence, and outcome of their simultaneous surgical correction.

Rectocoele and faecal incontinence coexist in most patients. We determined an excellent one-year outcome of simultaneous repair of the former and correction of the latter can be achieved.

Liver and Kidney Transplant During a 6-Month Period in the COVID-19 Pandemic: A Single-Center Experience.

Objectives: With the declaration of COVID-19 as a pandemic, many studies have indicated that elective surgeries should be postponed. However, postponement of transplants may cause diseases to get worse and increase the number in wait lists. We believe that, with precautions, transplant does not pose a risk during pandemic.

Long-term and Perioperative Outcomes of Laparoscopic and Open Surgery for Rectal Cancer.

Objectives: The necessity of comparing oncologic results with the use of minimally invasive surgery in rectal cancer has arisen. The aim of the present study was to evaluate the treatment approach in rectal cancer and to compare the outcomes of laparoscopic and open surgery.

Methods: Patients who underwent surgery for rectal carcinoma between January 2006 and January 2016 in our institution were evaluated.

Increased Mortality Among Renal Transplant Patients With Invasive Pulmonary Aspergillus Infection.

Introduction: Renal transplantation is the most effective and preferred definite treatment option in patients with end-stage renal disease. Due to long-term immunesuppressive treatment, renal transplant recipients become vulnerable to opportunistic infections, especially to fungal infections.

Method: This was a single-center, retrospective observational study of 438 patients who underwent renal transplantation between 2010 and 2016.

Reconstruction of Traumatic External Iliac Artery Dissection Due to Vascular Clamping.

Traumatic external iliac artery dissection after renal transplant is a rare complication, but it should be urgently managed due to its devastating effects on graft and lower limb circulation. External iliac artery dissection is seen more in recipients with diabetes mellitus and comorbid disease. Recipients with external iliac artery dissection should be treated immediately by percutaneus angioplasty or surgical reconstruction.

Evaluation of Transplanted Kidneys and Comparison with Healthy Volunteers and Kidney Donors with Diffusion-Weighted Magnetic Resonance Imaging: Initial Experience.

Objectives: The aim of this study was to evaluate the feasibility of diffusion-weighted magnetic resonance, by comparing imaging in renal allograft recipients for functional assessment of kidney transplants versus imaging of these features in healthy volunteers and kidney donors with native kidneys.

Materials And Methods: Seventy renal transplant recipients (group A) with stable graft function at postoperative month 1, 40 healthy volunteers (group B), and 40 kidney donors (group C) underwent diffusion-weighted magnetic resonance imaging. An echo-planar diffusion-weighted imaging sequence was performed in coronal orientation by using 6 b values (0, 200, 400, 600, 800, 1000 s/mm²).

Surgical Complications After Kidney Transplantation.

Since the first successful organ transplant conducted between twins in 1954, kidney transplant has evolved considerably over the past 50 years. Kidney transplant plays an important role in the treatment of end-stage kidney disease to improve the quality of life and prolong the life of patients. Despite significant advances, postoperative medical and surgical complications still represent important causes of morbidity and mortality.

The Outcomes of Ultralow Anterior Resection or an Abdominoperineal Pull-Through Resection and Coloanal Anastomosis for Radiation-Induced Recto-Vaginal Fistula Patients.

Purpose: The purpose of this study was to evaluate the outcomes of patients who underwent colorectal resections and coloanal anastomosis for radiation-induced recto-vaginal fistulas (RVFs). The effect of the surgical treatment technique on bowel function, fecal continence, and quality of life of patients was also evaluated.

Methods: Twenty-one female patients, who received adjuvant chemotherapy and external beam pelvic radiation for cervix carcinoma after radical hysterectomy + pelvic/paraaortic lymph node dissection, having RVF but without tumor recurrence, were included.

Results of liver transplant in elderly patients: a single center experience.

Objectives: With the increased life span, the need for liver transplant for elderly patients also increased in the world. In this study, we reviewed our experience to determine the outcomes and problems of patients aged > 60 years who had liver transplants.

Materials And Methods: Data of recipients aged > 60 years were reviewed retrospectively.
