Article Böbrek Naklinde de Novo Uzamış Salınımlı Takrolimus Kullanımı Sonuçları: Tek Merkez, 1 Yıllık Sonuçlar(2022) Sarıyıldız, Gülçin Türkmen; Demir, Mehmet Emin; Sezer, Siren; Sozener, Ulas; Ercan, Zafer; Gulen, Merter; Özşeker, Fatma NeclaAmaç: Böbrek nakli alıcılarında günde tek doz uzamış salınımlı takrolimus (tac-ER) kullanımı, erken salınımlı takrolimus (tac-IR) kullanımına benzer etkinlik ve daha iyi ilaç uyumu sağlaması amacıyla geliştirilmiştir. Ancak uzamış salınımlı takrolimus ile ilgili deneyimler daha çok nakil sonrası dönemde yapılan “switch” protokollerine dayanmaktadır. Bu çalışmada böbrek alıcılarında de novo tac-ER kullanımı ile ilgili deneyimlerimizi ve 1 yıllık sonuçları sunmayı amaçladık. Gereç ve Yöntem: Bu tek merkezli retrospektif çalışmaya Ocak 2022-Ocak 2021 arasında yapılan 72 de novo böbrek nakli hastası dahil edilmiştir. Hastalar tac- ER ve tac-IR alan iki gruba ayrıldı. Bir yıllık allogreft fonksiyonları ve sağ kalımları, hastaların günlük ilaç dozları ve bunların akut rejeksiyon atakları ile ilişkileri karşılaştırıldı. Allogreft fonksiyonları ve akut rejeksiyon atakları üzerine etki eden faktörler incelendi. Bulgular: Toplam 69 hastanın (uzamış salınımlı grupta 30 hasta ve erken salınımlı grupta 39 hasta) verileri incelendi. Üç hasta posttransplant erken dönemde öldüğü için analize dahil edilmedi. Nakil sonrası 12 aylık izlem boyunca her iki grup arasında serum kreatinin ve takrolimus çukur değerler bencer bulundu (p>0,05). İlk 3 ay içinde hedef takrolimus değerlere ulaşmak için, tac-ER grubunda daha yüksek günlük dozlar (milligra/gün ve milligram/gün/kg) gerekti (p<0,05). Nakil sonrası ilk 12 ay içinde her iki grupta da rejeksiyon oranları benzerdi (p=0,281). Tek değişkenli analizde posttransplant 1. aydaki takrolimus dozu (milligram/kg/gün) takrolimus çukur değerinin aksine rejeksiyon gelişimi üzerinde etkili görüldü (p=0,02). Sonuç: Böbrek naklinde uzamış salınımlı takrolimusun (Advagraf®) de novo kullanımı, erken salınımlı takrolimus kullanımına benzer etkinlik, allogreft sağ kalımı ve fonksiyonu sağlar.Article Fistulectomy and Primary Sphincteroplasty for Transsphincteric Fistula(Coll Physicians & Surgeons Pakistan, 2025) Emral, Ahmet Cihangir; Gulen, Merter; Ege, BahadirObjective: To evaluate the results of patients treated with fistulectomy and primary sphincteroplasty for uncomplicated perianal fistula. Study Design: Observational study. Place and Duration of the Study: Medicana International Hospital affiliated with Atilim University, Faculty of Medicine, Ankara, Turkiye, from January 2020 to September 2023. Methodology: In this study, patients who were operated on for perianal fistula between 2020 and 2023 were retrospectively examined. Data were obtained retrospectively. All patients underwent preoperative perianal MRI. Clinical notes were evaluated with the Cleveland Clinic Incontinence Score (CCIS) by physical examination. All patients were followed up on the first postoperative day, 1st week, 1st and 3rd postoperative months. Results: A total of 44 patients who underwent fistulectomy with primary sphincteroplasty were included in the study. Twenty-six patients (59.1%) had a history of perianal abscesses. It was observed that 34 (77.3%) of the patients had posterior, 7 (15.9%) anterior, and 3 (6.8%) lateral fistulas. A total of 3 patients (6.8%) were observed to have minor worsening in their incontinence scores. There was no statistically significant difference between the preoperative and postoperative 3rd month Cleveland Clinic Incontinence Score values of the patients (CCIS mean 1.6 vs. 1.7, respectively, p >0.05). Recurrence was observed in 1 patient (2.3%) during follow-ups. Conclusion: Fistulectomy with primary sphincteroplasty is an effective and reliable method to preserve anal continence and improve quality of life.Article Citation - WoS: 4Citation - Scopus: 5Evaluating Efficacy and Outcomes: Comparison of Laser Treatment and Crystallized Phenol in Pilonidal Sinus Disease(Frontiers Media Sa, 2025) Emral, Ahmet Cihangir; Gulen, Merter; Ege, BahadirObjective The aim of this study is to comprehensively evaluate the efficacy of laser ablation and crystallized phenol application in the treatment of pilonidal sinus disease, focusing on treatment success, recurrence rates, complications, and the patients' return to normal life.Material and method Data from patients treated for pilonidal sinus disease with laser ablation and crystallized phenol application at our clinic between January 2020 and September 2023 were retrospectively reviewed. Preoperative data including pit counts, disease stage, preoperative pilonidal abscess history, disease duration (week), treatment success, recurrence/persistent disease, postoperative complications, healing time (days), and visual analogue scale (VAS) scores on postoperative days 1 and 7, as well as return to normal life (days), were analyzed.Results A total of 121 patients were included in the study, with 51 receiving laser ablation and 70 receiving crystallized phenol application. The postoperative outcomes revealed that the wound healing period and postoperative VAS values were statistically significantly better in the laser ablation group.Conclusion Wound healing was faster and postoperative pain was less in the laser group compared to the phenol group. According to this study, both methods can successfully treat the disease in selected cases.Article Which Technique Is Preferable for Grade 2-3 Hemorrhoidal Disease: Laser Vs. Rubber Band Ligation ? A Retrospective Study(Springernature, 2025) Emral, Ahmet Cihangir; Gulen, Merter; Ege, BahadirBackground The aim of this study is to compare the short and long-term results (postoperative pain, complications, return to daily life, recurrence) between patients who underwent laser hemorrhoidoplasty (LH) and rubber band ligation (RBL) due to grade 2-3 hemorrhoidal disease. Methods The results of patients who underwent LH and RBL between June 2020 and June 2023 for grade 2-3 hemorrhoidal disease were evaluated retrospectively. The patient information was examined in terms of operation time, postoperative 1st, 7th and 14th day visual analog scale (VAS) values, the amount of analgesic used in the first 7 postoperative days, return to normal life (days), recurrence within 1 year and other complications (postoperative bleeding, thrombosis, urinary retention, infection/abscess, anal stenosis, deterioration in continence). Results A total of 260 patients were included in the study, 166 of whom underwent RBL and 94 LH. Operation time, VAS values, postoperative 7-day analgesic use (mg), worsening of incontinence, time to return to normal life (days), complications and recurrence within 1 year evaluated. LH has statistically significant lower postoperative 1st day pain and less analgesic use (mg) than RBL (p < 0.001). Conclus & imath;ons LH and RBL both offer effective treatment options for grade 2-3 hemorrhoidal disease, with comparable recurrence rates and time to return to normal life. However, LH is associated with significantly less postoperative pain and analgesic use on the first postoperative day, potentially enhancing patient satisfaction.
