| 1 | Role of laparoscopic common bile duct exploration in the management of choledocholithiasis显示文摘Surgical fraternity has not yet arrived at any consensus for adequate treatment of choledocholithiasis. Sequential treatment in the form of pre-operative endoscopic retrograde cholangio-pancreatography followed by laparoscopic cholecystectomy(LC) is considered as optimal treatment till date. With refinements in technique and expertise in field of minimal access surgery, many centres in the world have started offering one stage management of choledocholithiasis by LC with laparoscopic common bile duct exploration(LCBDE). Various modalities have been tried for entering into concurrent common bile duct(CBD) [transcystic(TC) vs transcholedochal(TD)], for confirming stone clearance(intraoperative cholangiogram vs choledochoscopy), and for closure of choledochotomy(T-tube vs biliary stent vs primary closure) during LCBDE. Both TC and TD approaches are safe and effective. TD stone extraction is involved with an increased risk of bile leaks and requires more expertise in intra-corporeal suturing and choledochoscopy. Choice depends on number of stones, size of stone, diameter of cystic duct and CBD. This review article was undertaken to evaluate the role of LCBDE for the management of choledocholithiasis. | Nikhil Gupta | 2016 | World Journal of Gastrointestinal Surgery2016，8，5： | 40 |
| 2 | Optimal distributed generation allocation in radial distribution systems considering customer-wise dedicated feeders and load patterns显示文摘Distribution system planners usually provide dedicated feeders to its different class of customers,each of whom has its own characteristic load pattern which varies hourly and seasonally.A more realistic modeling should be devised by considering the daily and seasonal variations in the aggregate load patterns of different class of customers.This paper addresses a new methodology to provide integrated solution for the optimal allocation of distributed generations and network reconfiguration considering load patterns of customers.The objectives considered are to maximize annual energy loss reduction and to maintain a better node voltage profile.Bat algorithm(BA)is a new bio-inspired search algorithm which has shown an advance capability to reach into the promising region,but its exploration is inadequate.The problem is solved by proposing the improved BA(IBA).The proposed method is investigated on the benchmark IEEE 33-bus test distribution system and the results are very promising. | Neeraj KANWAR Nikhil GUPTA K.R.NIAZI Anil SWARNKAR | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，4： | 16 |
| 3 | Evaluation of graphite depressants in a poly-metallic sulfide flotation circuit显示文摘Synthetic dyes are commonly used for graphite depression in poly-metallic flotation circuits; however,these dyes can be very expensive. The aim of this study is to evaluate performance of certain low-cost alternative depressants for a complex lead-zinc(Pb-Zn) ore rich in graphite(Gr-C) on a conventional mini pilot-scale flotation circuit. The reagents used were commercial and industrial grade starch; agro-based waste-sugarcane bagasse and charred(burnt) bagasse powder. The primary evaluation criteria were quality(grades) of lead and zinc concentrates, their recoveries(%), and graphite rejection(%) in the tails.Benchmark tests using nigrosine as graphite depressant showed 94.3% rejection of Gr-C. The results with commercial starch were found as effective with 93.8% graphite rejection. Furthermore, bagasse powder showed potential in improving product quality(36.4% and 65.6% Pb grade and recovery) with an intermediate effectiveness in graphite rejection(85.6%). The order of effectiveness in Gr-C rejection follows nigrosine % commercial starch > bagasse > industrial starch > charred bagasse. In addition, the effect these depressants on silver(byproduct) grade and recovery was also investigated. | Nikhil Gupta | 2017 | International Journal of Mining Science and Technology2017，27，2： | 5 |

| 6 | Robotic assisted laparoscopic simple suprapubic prostatectomy--The Smith Institute for Urology experience with an evolving technique显示文摘Objective:Despite a multitude of minimally invasive surgical options available for benign prostatic enlargement,open simple prostatectomy(OSP)remains the standard for large prostates(typically greater than 100 g).OSP,however,is associated with significant morbidity.Recently,a few reports touting robotic application to simple prostatectomy have been published.Herein,we reviewed our series of robotic assisted laparoscopic simple suprapubic prostatectomy(RALSSP)and detailed modifications in our technique as our experience increased.Methods:All RALSSP cases performed between January 2013 and January 2014 were reviewed for demographics,pre-operative features,and perioperative outcomes.All parameters were tabulated and mean values were calculated.Student’s t-test was utilized with p<0.05 deemed significant.Details regarding surgical technique were reviewed and highlighted.Results:Fifteen patients underwent RALSSP during this period.Mean age of these men was 68.7 years.Mean body mass index(BMI)was 28.5 kg/m^2.American Society of Anesthesiologists(ASA)score was on average 2.6.Average International Prostate Symptom Score(IPSS)was 16.2 with the majority of men experiencing some adverse clinical sequela of such benign prostatic hyperplasia(BPH).For those patients not in retention,preoperative post-void residual(PVR)was 428 mL.All patients underwent successful RALSSP without need for conversion or need for blood transfusion.Mean estimated blood loss(EBL)was 290 mL.Five patients underwent other concurrent procedures(e.g.,cystolithotomy).Mean length of hospital stay(LOS)was 2.4 days and only five patients required continuous bladder irrigation(CBI)postoperatively.Postoperative PVR improved to a mean of 33 mL and IPSS improved to 4.5(p<0.001).No major complications were identified.Adaptation of low transverse cystotomy,utilization of a robotic tenaculum in the#3 arm with its control by a surgeon on a second console,and the utilization of mucosal advancement have all subjectively aided in performance of RALSSP and perioperative outcomes.Conclusion:RALSSP allows for feasible performance of prostate adenoma enucleation with low risk of blood transfusion,short LOS,and significant improvement in IPSS and PVR;all while maintaining a minimally invasive approach.The use of a robotic tenaculum controlled by the secondary console and the mucosal advancement facilitate excellent outcomes and may play a role in minimizing hematuria and need for CBI. | Sammy E.Elsamra Nikhil Gupta Haris Ahmed David Leavitt Jessica Kreshover Louis Kavoussi Lee Richstone | 2014 | Asian Journal of Urology2014，1，1： | 2 |
| 7 | Triple tube drainage for “difficult” gastroduodenal perforations:A prospective study显示文摘AIM To prospectively study the outcome of difficult gastroduodenal perforations(GDPs) treated by triple tube drainage(TTD) in order to standardize the procedure.METHODS Patients presenting to a single surgical unit of a tertiary hospital with difficult GDPs(large, unfavourable local and systemic factors) were treated with TTD(gastrostomy, duodenostomy and feeding jejunostomy). Postoperative parameters were observed like time to return of bowel sounds, time to start enteral feeds, time to start oral feeds, daily output of all drains, time to clamping/removal of all drains, time for skin to heal, complications, hospital stay, and, mortality. Descriptive statistics were used. RESULTS Between December 2013 and April 2015, 20 patients undergoing TTD for GDP were included, with mean age of 44.6 ± 19.8 years and male:female ratio of 17:3. Mean pre-operative APACHE Ⅱ scores were 10.85 ± 3.55; most GDPs were prepyloric(9/20; 45%) or proximal duodenal(8/20; 40%) and mean size was 1.83 ± 0.59 cm(largest 2.5 cm). Median times of resumption of enteral feeding, removal of gastrostomy, removal of duodenostomy,removal of feeding jejunostomy and oral feeding were 4 d(4-5 IQR), 13(12-16.5 IQR), 16(16.25-22.25 IQR), 18(16.5-24 IQR) and 12 d(10.75-18.5 IQR) respectively. Median hospital stay was 22 d(19-26 IQR) while mortality was 4/20(20%). CONCLUSION TTD for difficult GDP is feasible, easy in the emergency, and patients recover in two-three weeks. It obviates the need for technically demanding and riskier procedures. | Nitin Agarwal Nishant Kumar Malviya Nikhil Gupta Iqbal Singh Sanjay Gupta | 2017 | World Journal of Gastrointestinal Surgery2017，9，1： | 1 |
