Rendez-vous technique was used in \n2 patients for eventual placement of metallic stents. Clinical \nimprovement evidenced with dropping bilirubin levels, \nresolving jaundice and sepsis-related symptoms were seen in \nall patients. Two-step external drainage with later conversion \nto internal metallic-stent drainage was performed in 2 patients. \nSingle-step internal-external drainage was performed in \n12 patients. No major complications were reported. Minor \ncomplications included fever, self-limiting intra-catheter \nbleed, skin infection, transitional catheter blockage and partial \ncatheter dislodgment. Conclusions:  PTBD remains an efficient \nmethod in the treatment of biliary obstruction in patients with \nfailed retrograde endoscopic therapy. Our small series shows \nthat PTBD remains the final resort in patients with failed \nendoscopic therapy in addition to its proven role as an initial \napproach for biliary decompression.\nP407\nTo Compare the Efficacy and Complications of \n16 Gauge and 18 Gauge Trucut Biopsy Needle in \nUltrasound Guided Percutaneous Liver Biopsies\nSadia Rashid, Junaid Iqbal\nDow University of Health Sciences, Karachi, Pakistan.  \nE‑mail: dr_sadiarashid@yahoo.com\nBackground:  Ultrasound guided percutaneous liver biopsy \nis the gold standard for characterization of liver lesions and \ndetermination of diffuse liver disease and liver fibrosis. It is an \neasy but invasive method which sometimes may cause severe \ncomplications. Methods:  This is a prospective study conducted \nfrom January 2016 to December 2016. A  total of 426 patients \nwere included in the study, out of which 244 (57.3%) were \nmales while 182 (42.7%) were females. Mean age of the \npatients was 54.62 ± 13.25 years. 202 (47.41%) patients \nunderwent liver biopsy by 16 gauge trucut biopsy needle while \n224 (52.58%) patients had biopsies using 18 gauge needle. \nResults:  Overall, mild pain was found in 86 (20.2%) patients, \nsevere pain in 36 (8.5%) patients, vasovagal in 13 (3.1%) \npatients, local hematoma in 12 (2.8%), severe hemorrhage in \n3 (0.7%), pneumothorax in 2 (0.5%) patients while 20 (4.7%) \nsamples were inadequate. Comparison of complications in \nboth groups showed that except inadequate specimen and \nsevere pain, insignificant association of complications was \nobserved in both group. Number of inadequate specimen was \nsignificantly higher in patients who underwent biopsy by 18 \ngauge trucut needle as compared to the patients who underwent \nbiopsy by 16 gauge needle ( P value 0.001). Severe pain was \nsignificantly higher in patients who underwent biopsy by 16 \ngauge needle as compared to 18 gauge needle ( P value 0.016). \nConclusions:  Ultrasound guided percutaneous liver biopsy \nusing either 16 or 18 gauge trucut needle is safe and effective \nmethod to characterize liver lesions with very low rate of \ncomplications. However 16 gauge needle should be preferred \nas the inadequacy of specimen in our study was higher for 18 \ngauge needle.\nP408\nPercutaneous Cryoablation of Symptomatic \nAbdominal Wall Endometriosis: Mid-Term \nOutcomes and Comparison with Surgery Alone \nin a Single Institution\nFrancois H. Cornelis, Julie Maillot 1, \nJean Luc Brun 1, Nicolas Grenier 1\nTenon Hospital, Paris, 1Pellegrin Hospital, Bordeaux, France.  \nE‑mail: francoiscornelis@hotmail.com\nBackground: To compare the outcomes of percutaneous \nimage-guided cryoablation of symptomatic abdominal wall \nendometriosis (AWE) versus surgery alone. Methods: From \n2004 to 2016, cryoablation or surgery alone was performed \nfor AWE in a single institution in 7 (mean age: 36.1 y) and \n13 (mean age: 31.9 y) patients, respectively. Fifteen lesions were \ntreated by cryoablation (mean size: 2.3 cm; range 0.5-7 cm) \nand 16 by surgery (2.5 cm; 1.1‑3.4 cm). Tolerance, efficacy \nand patient and procedural characteristics were compared. \nResults: Median follow-up was 22.5 (range: 6-42) months after \ncryoablation and 54 (14-149) after surgery. The median procedure \nand hospitalization durations were 41.5 minutes (24-66) and \n0.8 days (0-1) after cryoablation, and 73.5 minutes (35-160) \nand 2.8 days (1-12 days) after surgery (both  P = 0.01). Fifteen \npatients had general and 5 had local anesthesia (3 cryoablations \nand 2 surgery). Three patients (23.1%) had severe complications \nand 9 esthetic sequels (69.2%) after surgery, none after \ncryoablation (P = 0.05). The median 12 and 24-month symptom \nfree-survival rates were 100% and 66.7% [95%CI: 5.4; 94.5] \nafter cryoablation and 92% [55.3; 98.9] after surgery at both time \npoints ( P = 0.45). Conclusions: Cryoablation presents similar \neffectiveness to surgery alone for local control of AWE while \nreducing hospitalization duration and complications.\nP501\nEfficacy of Trans‑arterial Chemoembolization \nin Combination with Percutaneous Ethanol \nInjection for Hepatocellular Carcinoma\nMuhammad Shozab Ahmed, Atif Rana, \nMaham Jehangir\nShifa International Hospital, Islamabad, Pakistan.  \nE‑mail: muhammedshozab@gmail.com\nBackground: To evaluate combined efficacy of trans‑arterial \nchemoembolization (TACE) using drug eluting beads, \nHepasphere (Merit medical, USA), with percutaneous ethanol \ninjection (PEI) for hepatocellular carcinoma (HCC) a retrospective \nreview was conducted. Methods: During January 2015 to January \n2017, 34 patients with hepatocellular carcinoma underwent \ncombined therapies (TACE + PEI). Out of these two patient’s \nwere excluded because lipid was used.The tumour response at \n3 months, 6 months, 12 months and 24 months was evaluated \nusing a pre‑defined criterion. Results: Most of the tumours were \nlocated in right lobe. The tumour size ranged from 1-10 cm with \nmean size of 4.2 cm. The average amount of alcohol used was \n12 ml. The tumour response rates in the combined TACE + PEI \nshowed more than 90% reduction in arterialisation at 3 and \nArticle published online: 2021-04-26","source_license":"CC0","license_restricted":false}
