Perbedaan Kesintasan Satu Tahun antara Prosedur Biliodigestive Double Bypass dan Pemasangan Sten Bilier per Endoskopik sebagai Terapi Paliatif pada Pasien Striktur Bilier Distal Maligna di RSCM = One Year Survival Difference between Biliodigestive Double Bypass Procedure and Placement of Endoscopic Stent as Palliative Therapy in Patients with Malignant Distal Biliary Stricture in RSCM.

Latar Belakang. Striktur bilier ditemukan pada 70-90% kasus keganasan pankreatobilier dan menimbulkan morbiditas dan mortalitas yang tinggi terutama pada stadium lanjut yang unresectable. Pada stadium tersebut, tata laksana paliatif bertujuan untuk meningkatkan kualitas hidup pasien dan memperbaiki kesintasan. Tata laksana paliaitf yang dapat dilakukan adalah dengan pemasangan sten bilier perendoskopik dan operasi pintas saluran bilier. Sehingga, perlu diketahui perbedaan kesintasan satu tahun pasien dengan striktur bilier maligna yang mendapatkan terapi paliatif dengan prosedur biliodigestive double bypass dan pemasangan sten bilier perendoskopik di RSCM. Tujuan. Mengetahui perbedaankesintasan antara pasien striktur bilier distal maligna yang menjalani prosedur double bypass dan prosedur pemasangan sten bilier per endoskopik. Metode. Penelitian dilakukan dengan metode kohort retrospektif dengan subyek penelitian pasien striktur bilier maligna distal yang menjalani prosedur pemasangan sten perendoskopik atau prosedur double bypass di RSCM pada periode 1 Januari 2015 – 31 Desember 2019 dan dilakukan pengamatan selama 1 tahun sejak pasien menjalani prosedur tersebut. Kesintasan dinilai dengan metode Kaplan-Meier dan dilanjutkan dengan analisis multivariat terhadap faktor-faktor yang dinilai dapat menjadi faktor perancu. Hasil. Penelitian ini berhasil mengumpulkan 119 subjek pada kelompok sten endoskopik dan 39 subjek pada kelompok double bypass. Pada pengamatan kesintasan satu tahun, didapatkan median kesintasan 93 hari pada kelompok sten endoskopik dan 140 hari pada kelompok double bypass [HR 0,871 (IK95% 0,551-1,377; p = 0,551)]. Tidak ditemukan perbedaan kurva kesintasan pada kedua kelompok. Pada analisis multivariat, didapatkan Charlson Comorbidity Index, usia, dan bilirubin adalah variabel perancu. Kesimpulan. Tidak terdapat perbedaan kesintasan antara pasien striktur bilier distal maligna yang menjalani prosedur double bypass dan prosedur pemasangan sten bilier perendoskopik. Usia, CCI ≥ 4, dan kadar bilirubin merupakan faktor perancu terhadap kesintasan kesintasan antara pasien striktur bilier distal maligna yang menjalani prosedur double bypass dan prosedur pemasangan sten bilier per endoskopik

Background. Biliary strictures are observed in 70-90% of cases of pancreatic malignancy and cause high morbidity and mortality, especially in advanced, unresectable stage. At this stage, palliative management aims to improve the patient's quality of life and survival. Palliative management can be done is by placing an endoscopic biliary stent and biliary tract bypass surgery. Thus, it is necessary to know the one-year survival of patients with malignant biliary stricture who received palliative therapy with billio-digestive double bypass procedures and perendoscopic biliary stent placement in RSCM. Objective. To determine the survival between patients with distal malignant biliary stricture who underwent a double bypass procedure and an endoscopic biliary stent placement procedure. Methods. This is a restrospective cohort study with the subjects being patients with distal malignant biliary strictures who underwent endoscopic stenting procedures or double bypass procedures at RSCM in the period 1 January 2015 – 31 December 2019 and was observed for one year since the patient underwent the procedure. Survival was done using the Kaplan-Meier method and followed by multivariate analysis using the cox regression test. Result. We collected 119 subjects in the endoscopic stent group and 39 subjects in the double bypass group. After one year, median survival was 93 days in the endoscopic stent group and 140 days in the double bypass group [HR 0,871 (95%CI 0,551-1,377; p = 0,551)]. In multivariate analysis, it was found that Charlson Comorbidity Index, age, and bilirubin were confounding variables. Conclusion. There was no difference in survival between patients with malignant distal biliary stricture who underwent a double bypass procedure and an endoscopic biliary stent procedure. Age, CCI 4, and bilirubin levels were confounding factors for survival among patients with malignant distal biliary stricture who underwent a double bypass procedure and an endoscopic biliary stent placement procedure.
