for patient with neck-located cancer with BDR, and 79.5% for those without BDR. Conclusions: Considering the location of tumor, the optimal procedure for each patients should be considered. In patients with hepatic-side cancer, HR is effective pro- cedure for improving survival. BDR is considered to be additional procedure for improving survival in selected patient with neck-located cancer. EP03B-029 ROBOTIC RADICAL CHOLECYSTECTOMY WITH HISTOLOGICAL SURPRISE S. Sabnis, P. Senthilnathan, V. P. Nalankilli, S. Srivatsan Gurumurthy, N. Anand Vijai and C. Palanivelu Surgical Gastroenterology & HPB Surgery, Gem Hospital and Research Center, India Introduction: Gallbladder cancer is the most common malignant tumor of the biliary system. The only potentially curative option for patients with gallbladder cancer is radical resection. This is one of the early reports first that describes the successful application of robotic radical cholecystectomy in a locally gallbladder cancer patient. Methods: A 46-year-old gentleman with no comorbidities presented with dull aching right hypochondrial pain for 1 month. His per abdomen examination, liver function and renal function tests were essentially normal. CECT abdomen showed locally advanced mass in gallbladder infiltrating segment 4b and 5. With this he was diagnosed to have locally advanced carcinoma of gallbladder. Robotic radical cholecystectomy was contemplated with lympha- denectomy. On staging laparoscopy showed no evidence of intraabdominal metastasis. Cystic duct arose from right hepatic duct. Frozen section of cystic duct showed no ev- idence of malignancy. Liver resection of Segment 4b and 5 was done using the help of CUSA and bipolar diathermy. The procedure was successfully completed in 320 minutes. Blood loss was 150 ml. There was no intraoperative com- plications and drain was removed on post-operative day 5, then discharged on the same day. Histopathology report revealed - moderately differentiated squamous cell carci- noma with no malignancy in 7 lymph nodes examined, (pT3N0M0). He was subjected for adjuvant therapy. Conclusion: The robotic radical cholecystectomy in locally advanced carcinoma gallbladder is safe and feasible. With robotic surgery system well suited for subtle dissections in a deep and narrow space, this has the potential to be viable. EP03B-030 RESIDUAL DISEASE IN INCIDENTAL GALLBLADDER CANCER: RISK STRATIFICATION AND OUTCOME L. Gil 1 , J. Lendoire 1 , F. Duek 1 , J. Hepp 2 , X. Darexabala 2 and O. Imventarza 1 1 Hospital Argerich, Argentina, and 2 Clinica Alemana, Chile Background: Residual disease (RD) has become the most relevant prognostic variable after resection for incidental gallbladder cancer. Methods: Consecutive patients with IGC undergoing re- exploration between 1990- 2014 were identified. Those patients submitted to a radical definitive resection were analyzed. Demographics and tumor-treated related vari- ables were correlated with RD and survival. Cancer specific survival correlated with the site of RD, local (gallbladder bed) or regional (lymph nodes & bile duct). Results: Of 265 patients with incidental gallbladder cancer submitted, re-resection was performed in 168 and RD was found in 58 (34.5%).Comparison of demographic, clinical and surgical variables showed differences in type of resection, more than 5 nodes resected, T stage and disease stage (< 0.0001).Site of RD was regional in 34 (20.2%), local in 24 (14,3%).The T stage ( p< 0.001)and disease stage(p= < 0.001) were independent predictors of RD. Presence of RD at any site reduced the disease specific survival (DSS) (19.6 month vs 62.7 month p< 0.001) in comparison with non RD patients. There was no difference in DSS according the location of RD, with all anatomic sites been equally poor (p= 0.27). RD at any site predicted DSS (p< 0.001), independent of all other tumor related variables. Conclusions: Residual disease is a critical prognostic factor in patients with IGC treated by radical resection. Outcome was poor in the presence of RD regardless of the anatomic location. Future studies with new adjuvant pro- tocols are needed to improve survival in this setting. EP03B-031 DOES PALLIATION OF JAUNDICE BY PTBD IMPROVE THE PHYSICAL QUALITY OF LIFE IN PATIENTS WITH INOPERABLE GALL BLADDER CANCER AND SURGICAL OBSTRUCTIVE JAUNDICE (SOJ)? S. Chauhan, S. Kumar, S. Masood, A. Pandey and D. Kumar Surgical Gastroenterology, Ram Manohar Lohia Institute of Medical Sciences, India Aim: To ascertain the quality of life in patients undergoing PTBD for palliation of surgical obstructive jaundice (SOJ) in inoperable cases of carcinoma gall bladder with jaundice. Method: From January 2016 to November 2017, 32 pa- tients of inoperable carcinoma gallbladder with jaundice underwent PTBD with palliative intent. 18 such Patients followed up and were assessed by FACT-HEP and EORTC QLQ BIL 21 questionnaire pre-procedure, post-procedure, and one month post-procedure. Thereafter patients were followed up monthly. Patients unwilling to enroll for the study or those lost to follow up were excluded. Results: Mean age 54.17 yrs , M:F ratio = 1:1, type of PTBD, complications, procedure related mortality, cost of procedure, mean follow up was recorded. All the data along with the Questionnaire split analysis was done using the SPSS version 23. FACT HEP- factors that showed improvement - physical, social/family, emotional ,func- tional well being (p < 0.000) . Additional concerns related to symptoms also showed significant improvement (p < 0.000). PTBD tube related problems did not significantly affect QOL (p < 0.000). EORTC QLQ BIL21 - Improve- ment was seen in Eating symptom (p < 0.001), jaundice (p < 0.000), tiredness (p < 0.11), pain (p < 0.001), anxiety (p HPB 2018, 20 (S2), S685eS764 S710 Electronic Posters (EP03A-EP03F) e Biliary
