ABSTRACTBackgroundDelayed graft function (DGF) is a common complication affecting deceaseddonor renal transplantation. Based on previous studies, DGF and its risk factors inlive donor nephrectomy (LDN) have a various results.MethodsWe retrospectively analyzed the medical records of donor and recipient from ourfirst 100 cases of laparoscopic LDN in Cipto Mangunkusumo Hospital fromNovember 2011 to February 2014. The criteria used to define DGF were therequirement for dialysis in postoperative week 1 and/or serum creatinine greaterthan 2.5 mg/dl at postoperative day 7. Patients who did not match any of thesecriteria were define as having normal renal allograft function.ResultsThe overall prevalence of DGF was 14%. Recipients body mass index, coldischemia time, vascular anastomosis time, and total ischemia time were higheramong the delayed graft function group, but no risk factors for DGF weresignificantly associated after multivariate analysis.ConclusionsThe incidence of DGF in our study was in the range of that observed in previousstudies. The factors that previously reported and believed as risk factors of DGFin laparoscopic LDN were not significantly associated with the development ofDGF in our study.;BackgroundDelayed graft function (DGF) is a common complication affecting deceaseddonor renal transplantation.

"Obesitas adalah masalah kesehatan di seluruh dunia, menyebabkan 3,4 juta kematian per tahun. Obesitas dinilai merupakan kontraindikasi relatif untuk operasi laparoskopi. Nefrektomi donor hidup per laparoskopi merupakan prosedur baku emas untuk pengangkatan ginjal pada beberapa pusat transplantasi. Namun pemilihan donor obesitas untuk menjalani laparoskopi nefrektomi masih menjadi perdebatan. Tujuan penulisan ini adalah untuk membandingkan hasil jangka pendek donor obesitas dan non-obesitas yang menjalani nefrektomi donor hidup per laparoskopi. Pada penelitian ini dilakukan analisa retrospektif pada 259 donor hidup antara November 2011 dan Agustus 2015. Indeks massa tubuh lebih dari 30 kg/m2 dikategorikan obesitas. Dua puluh subjek termasuk dalam kategori donor obesitas. Kami melakukan pengambilan sampel acak untuk 30 donor non- obesitas sebagai kelompok kontrol. Data intraoperatif dan pascaoperatif dibandingan antara kedua kelompok. Nilai p ≤0,05 menunjukkan perbedaan bermakna. Karakteristik yang sama terdapat pada kedua kelompok donor. Tidak terdapat perbedaan bermakna pada waktu iskemik pertama, perkiraan kehilangan darah intraoperatif, dan nyeri pascaoperatif pada kedua kelompok. Waktu operasi pada donor obesitas lebih lama daripada kelompok kontrol (270 vs 245 menit, p≤0,05). Waktu lama rawat lebih panjang pada kelompok obesitas (4 vs 3 hari, p≤0,05). Pada rumah sakit kami, donor obesitas menunjukkan hasil jangka pendek yang sebanding dengan donor non-obesitas pada nefrektomi donor hidup per laparoskopi. Meskipun ditemukan waktu operasi yang lebih lama dan lama rawat yang lebih panjang, tidak terdapat komplikasi yang bermakna pada donor obesitas. Masih diperlukan evaluasi hasil jangka panjang untuk rasionalisasi donor obesitas.

Obesity is a major worldwide health problem, causing up to 3.4 million deaths per year. it was considered as a relative contraindication for laparoscopic surgery. Nowadays, Laparoscopic living donor nephrectomy is the gold standard procedure for kidney procurement in many transplant centers. However, the selection of the obese donors undergoes laparoscopic nephrectomies is still debatable. The objective of this study is to compare short-term results of obese donors and non- obese donors undergoing laparoscopic living donor nephrectomies. A retrospective analysis of 259 live donors between November 2011 and August 2015 was performed. Body mass index equal or more than 30 kg/m2 was categorized as obese. Twenty subjects were categorized as obese donors. We randomly assigned for 30 non-obese donors for the control group. Intra-operative and post-operative data were compared between these two groups. A p-value ≤0.05 was considered significant. There were same donors’ characteristics between two groups. No significant differences were found in the first warm ischemic time, estimated blood loss, and postoperative pain. The operative time in the obese group was significantly longer than in the control group (270 vs 245 minutes, p≤0.05). The hospital stay was also significantly longer in the obese group (4 vs 3 days, p≤0.05). At our hospital, obese donors show comparable short-term results to non-obese donors in laparoscopic living nephrectomy. While longer operative time and length of stay were found, there was no significant complication observed. Long-term outcomes should be evaluated for the rationalization of these obese donors. "

"Latar Belakang: Penolakan cangkok akut pascatransplantasi hati anak dapat berakibat cangkok tidak berfungsi. Angka kejadian yang mencapai 31% di Rumah Sakit Cipto Mangunkusumo (RSCM) membutuhkan evaluasi faktor risiko untuk mengurangi morbiditas dan mortalitas. Metode: Rekam medis 44 resipien anak pascatransplantasi hati donor hidup dari tahun 2010-Januari 2020 dievaluasi, dan dianalisa menggunakan fisher test. Hasil: Sebelas subjek (25%) mengalami penolakan cangkok akut pascatransplantasi dengan median waktu 12 hari (jarak waktu 6-70 hari) pascatransplantasi. Total 44 subjek, 29 (65,9%) berusia > 1 tahun dan 30 (68,1%) bergizi kurang. Kejadian penolakan cangkok akut pada kelompok usia ≤1 tahun, adalah 5 (33%) dan pada usia >1 tahun, 6 (20%). Penolakan cangkok akut terjadi pada 6 subjek (20%) dengan gizi kurang, dan 5 subjek (35,7%) dengan gizi baik. Hasil analisa menunjukkan tidak ada hubungan antara usia (p= 0,468; 95% CI 0,47-0,77; OR 1,917) dan status gizi (p=0,287; 95% CI 0,11- 1,85; OR 0,450) terhadap reaksi penolakan cangkok akut pascatransplantasi hati donor hidup anak di RSCM. Hasil observasi tiga bulan pertama memperlihatkan rerata kadar tacrolimus darah 6-8 ng/mL pada hari 12-15, tidak mencapai target untuk mendapatkan efek imunosupresi yang adekuat. Kesimpulan: Pada penelitian ini status gizi kurang dan usia resipien saat transplantasi hati tidak signifikan sebagai faktor risiko independen reaksi penolakan cangkok akut, tetapi dapat dipikirkan bahwa kedua faktor ini mempengaruhi imunitas resipien, yang selanjutnya berperan dalam reaksi penolakan cangkok akut. Penggunaan imunosupresan yang adekuat juga harus diperhatikan dalam menekan reaksi penolakan cangkok pascatransplantasi hati.

Background: Acute rejection post-liver transplant in children may result in graft failure. The incidence rate of up to 31% at Cipto Mangunkusumo Hospital (RSCM) needs further evaluation of risk factors to lower morbidity and mortality.

Methods: 44 medical records of post living donor liver transplant pediatric recipients between 2010 until January 2020 were evaluated and analyzed using Fisher’s test.

Results: Eleven subjects (25%) were found to experience acute rejection post-transplant with a median time of 12 days (range 6-70 days) after surgery. Of the 44 recipients, 29 subjects (65,9%) were >1 year old and 30 subjects (68,1%) were undernourished. Acute rejection occurred in 5 subjects (33%) ≤1 year-old and in 6 subjects (20%) that were >1 year old. Acute rejection of the transplant occurred in 6 subjects (20%) that were undernourished and in 5 subjects (35,7%) with good nutritional status. Analysis of the data found no relationship between age (p= 0,468; 95% CI 0,47-0,77; OR 1,917) and nutritional status (p=0,287; 95% CI 0,11-1,85; OR 0,450 to acute rejection in pediatric living donor liver transplant at RSCM. Observation in the first three months post-transplant reveal that mean levels of tacrolimus in the blood were 6-8 ng/mL on days 12-15, insufficient of reaching the target of obtaining an adequate immunosuppressive effect.

Conclusion: In this study, age and nutritional status of recipients during the time of transplant were found to be insignificant independent risk factors of liver transplant acute rejection. However, these two factors can be thought to effect recipients’ immune status, which plays a role in acute rejection post-transplant. The use of adequate immunosuppressant needs to be carefully monitored in suppressing rejection reactions post-liver transplant."

"Latar belakang: Komplikasi vena hepatika merupakan komplikasi vaskular pascatransplantasi hati yang penting karena dapat mengakibatkan kongesti hati, sirosis dan kegagalan cangkok, dengan insidens lebih tinggi pada Transplantasi Donor Hidup (LDLT) dibandingkan teknik transplantasi lainnya.Tujuan: Mengetahui parameter ultrasonografi (USG) Doppler vaskular vena hepatika periode awal pascatransplantasi yang dapat berperan sebagai prediktor komplikasi vena hepatikaMetode: Penelitian dilakukan pada 44 pasien pediatrik yang menjalani LDLT di RSUPN Dr. Ciptomangunkusumo dari tahun 2010 hingga Juli 2022 yang memiliki imaging USG Doppler vaskular pada hari pertama hingga ketiga pascatransplantasi. Kecepatan dan pola gelombang vena hepatika dari USG Doppler dievaluasi pada kelompok dengan dan tanpa komplikasi vena hepatika pada tahun pertama pascatransplantasi. Nilai titik potong kecepatan vena hepatika ditentukan menggunakan receiver operating curve.Hasil: Kecepatan vena hepatika pada hari kedua pascaoperasi secara signifikan lebih rendah pada pasien dengan komplikasi vena hepatika, dengan nilai tengah 21,3 (16,6-23,3) cm/detik, dibandingkan 28,9 (10,7-75,0) cm/detik pada pasien tanpa komplikasi vena hepatika, (nilai p = 0,018). Nilai titik potong kecepatan vena hepatika hari kedua pascaoperasi dalam membedakan komplikasi dan tanpa komplikasi vena hepatika adalah 23,65 cm/detik, sensitivitas 100%, spesifisitas 76,3%, AUC 0,803 (IK95% 0,679-0,927), dan nilai p = 0,018. Tidak terdapat perbedaan proporsi pola gelombang monofasik vena hepatika antara pasien dengan komplikasi vena hepatika dibandingkan dengan pasien tanpa komplikasi vena hepatika.Kesimpulan: Kecepatan vena hepatika yang rendah pada USG Doppler vaskular periode awal pascaoperasi terutama di hari kedua dapat membantu memprediksi komplikasi vena hepatika sehingga meningkatkan kewaspadaan dini terhadap komplikasi vena hepatika pada tahun pertama pascatransplantasi.

Background: Hepatic vein complication is an important postoperative complication in pediatric liver transplantation in which liver congestion may progress to cirrhosis and graft failure, with higher incidence in living donor liver transplantation (LDLT) compared to other liver transplantation technique.

Objective: This study aims to identify the role of Doppler ultrasound parameters of hepatic vein in early postoperative period of pediatric LDLT as predictors of hepatic vein complications.

Methods: From 2010 to July 2022, there were 44 pediatric LDLT patients in RSUPN Dr. Ciptomangunkusumo who had Doppler ultrasound imaging from first until third postoperative day. Hepatic vein velocity and waveform were compared in patients with and without hepatic vein complications in one year follow up. Cut off point of hepatic vein velocity is determined using receiver operating curve.

Results: Hepatic vein velocity in second postoperative day is significantly lower in patients with hepatic vein complication, with median of 21,3 (16,6-23,3) cm/s compared to 28,9 (10,7-75,0) cm/s in patients without hepatic vein complication (p value = 0,018), with cut off value to differentiate both group is 23,65 cm/s, sensitivity 100%, specificity 76,3%, AUC 0,803 (CI95% 0,679-0,927), and p value = 0,018. There is no difference in monophasic waveform proportion between patients with and without hepatic vein complication.

Conclusion: Lower hepatic vein velocity in early postoperative Doppler ultrasound of pediatric LDLT, especially in second postoperative day, may aid to predict hepatic vein complication in first year follow up. Such finding may increase awareness of hepatic vein complication in the first year after transplantation."
