| 1 | Robotic surgery for rectal cancer: A systematic review of current practice显示文摘AIM: To give a comprehensive review of current litera-ture on robotic rectal cancer surgery.METHODS: A systematic review of current literature via PubMed and Embase search engines was per-formed to identify relevant articles from january 2007 to november 2013. The keywords used were: 'robotic surgery', 'surgical robotics', 'laparoscopic computer-assisted surgery', 'colectomy' and 'rectal resection'. RESULTS: After the initial screen of 380 articles, 20 pa-pers were selected for review. A total of 1062 patients(male 64.0%) with a mean age of 61.1 years and body mass index of 24.9 kg/m2 were included in the review.Out of 1062 robotic-assisted operations, 831(78.2%) anterior and low anterior resections, 132(12.4%) in-tersphincteric resection with coloanal anastomosis, 98(9.3%) abdominoperineal resections and 1(0.1%) Hart-mann's operation were included in the review. Robotic rectal surgery was associated with longer operative time but with comparable oncological results and anastomotic leak rate when compared with laparoscopic rectal surgery. CONCLUSION: Robotic colorectal surgery has con-tinued to evolve to its current state with promising re-sults; feasible surgical option with low conversion rate and comparable short-term oncological results. The challenges faced with robotic surgery are for more high quality studies to justify its cost. | Tony Wing Chung Mak Janet Fung Yee Lee Kaori Futaba Sophie Sok Fei Hon Dennis Kwok Yu Ngo Simon Siu Man Ng | 2014 | World Journal of Gastrointestinal Oncology2014，6，6： | 16 |
| 2 | Combined resection and radiofrequency ablation for multifocal hepatocellular carcinoma: Prognosis and outcomes显示文摘AIM: To analyze the combined treatment of resection and intraoperative radiofrequency ablation (RFA) for multifocal hepatocellular carcinoma in terms of prognosis and surgical outcomes.METHODS: This study was a retrospective case comparison study using prospectively collected data. The study covered the period from April 2001 to December 2006. The data of 200 patients with histologically confirmed hepatocellular carcinoma were reviewed. Nineteen patients (17 men and 2 women) having received resection in combination with RFA were chosen as subjects of the study (the combination group). Fiftyfour patients (43 men and 11 women) having received resection alone were selected for comparison (the resection group). The two groups matched tumor number and tumor size, and all the patients in the two groups displayed no tumor rupture, major vascular involvement and distant metastasis. Their demographics, preoperative assessment, disease recurrence patterns, overall survival and diseasefree survival were compared.RESULTS: In the combination group, the medianage was 65 years (range, 3477 years), the median tumor number was 3 (range, 29), and the median tumor size was 6 cm (range, 1.214 cm). In the resection group, the median age was 51.5 years (range, 2780 years, P = 0.003), the median tumor number was 3 (range, 29, P = 0.574), and the median tumor size was 6 cm (range, 114 cm, P = 0.782). The two groups were similar in characteristics of tumors and comorbidities, and had comparable results in preoperative liver function tests. All patients had ChildPugh class A status. Bilobar involvement occurred in 14 patients (73.6%) in the combination group and 3 patients (5.5%) in the resection group (P = 0.04). Six patients (32%) in the combination group and 35 patients (65%) in the resection group underwent major hepatectomy. Thirteen patients (68%) in the combination group and 19 patients (35%) in the resection group underwent minor hepatectomy (P = 0.012). The combination group had fewer major resections (32% vs 65%, P = 0.012), less blood loss (400 vs 657 mL, P = 0.007), shorter operation time (270 vs 400 min, P = 0.001), and shorter hospital stay (7 vs 8.5 d, P = 0.042). The two groups displayed no major differences in surgical complications (15.8% vs 31.5%, P = 0.24), disease recurrence (63.2% vs 50%, P = 0.673), hospital mortality (5.3% vs 5.6%, P = 1), and overall survival (53 vs 44.5 mo, P = 0.496).CONCLUSION: Safe and effective for selected patients with multifocal hepatocellular carcinoma, the combination of resection and intraoperative RFA widens the applicability of surgical intervention for the disease. | Tan To Cheung Kelvin K Ng Kenneth S Chok See Ching Chan Ronnie T Poon Chung Mau Lo Sheung Tat Fan | 2010 | World Journal of Gastroenterology2010，16，24： | 14 |
| 3 | Impacts of different drying strategies on drying characteristics,the retention of bio-active ingredient and colour changes of dried Roselle显示文摘The drying kinetics of Roselle(Hibiscus sabdariffa L) of variety Terengganu(UMKL-1) and the quality attribution of Roselle were studied. The experiments were conducted using four different drying methods, including solar greenhouse drying(SD), solar greenhouse with intermittent heat pump drying(SIHP), hot air drying(HA) and heat pump drying(HP). Among the four drying methods, HP achieved the highest drying rate at a range from0.054 g H_2 O·(g DM)^(-1) ·min^(-1) to 0.212 g H_2 O·(g DM)^(-1)·min^(-1) while SD had the lowest drying rate, measured at 0.042 g H_2 O·(g DM)^(-1)·min^(-1).The analysis on colour kinetics revealed that there is no significant colour loss(p > 0.05) observed from HP's dried Roselle. Greater amount of flavonoid compounds i.e. protocatechuic acid was found in SD and SIHP dried finished product whereas HP's dried Roselle contains higher percentage of catechin as compared to other drying methods. | Thing Chai Tham Mei Xiang Ng Shu Hui Gan Lee Suan Chua Ramlan Aziz Luqman Chuah Abdullah Sze Pheng Ong Nyuk Ling Chin Chung Lim Law | 2018 | Chinese Journal of Chemical Engineering2018，26，2： | 7 |

| 5 | Double-row repair of rotator cuff tears: Comparing tendon contact area between techniques显示文摘BACKGROUND In rotator cuff repair surgery,the double-row technique is widely performed.Studies have shown that with increased contact area and pressure between tendon and bone interface,better healing is promoted.AIM To assess the different suture configurations with the double-row technique and how this influences the contact area of the rotator cuff tendon to bone.METHODS This was a controlled laboratory study where identical tears were created in 24 fresh porcine shoulders over a 1.5 cm×2.5 cm infraspinatus insertion footprint.Double-row repair techniques,with 3 to 4-suture anchors in different configurations(2 medial,2 lateral vs 2 medial,1 lateral vs 1 medial,2 lateral),were employed for three control groups.Each group consisted of eight shoulders with identical repair configurations.Footprint contact areas of the repaired tendon against the tuberosity were determined using pressure sensitive Fujifilm placed between the tendon and tuberosity.RESULTS The mean contact area between tendon and insertion footprint from the imprinted Fujifilm was obtained using computer software.The contact area measured from a standard 4-suture anchor double row repair was 75.1±9.3 mm2,whereas areas obtained for the 2 lateral-1 medial and 2 medial-1 lateral anchor configurations were 72.9±5.2 mm2 and 75.0±4.9 mm2 respectively.No statistical significance was noted between the three groups.CONCLUSION In the technique of double-row repair,using a 3-suture anchor configuration may offer a non-inferior alternative to the standard 4-anchor construct in terms of efficacy.This may also result in overall cost reduction and shorter surgical time. | Shao Hui Allan Ng Chung Hui James Tan | 2020 | World Journal of Orthopedics2020，11，1： | 6 |

| 7 | A case of laparoscopic hepatectomy for recurrent hepatocellular carcinoma显示文摘Conventional hepatectomy is an effective way to treat hepatocellular carcinoma.However,it is invasive and stressful.The use of laparoscopy in hepatectomy,while technically demanding,reduces surgical invasiveness and stressfulness but still achieves complete resection with adequate margins.Compared with conventional hepatectomy,laparoscopic hepatectomy provides a better chance and situation for further surgery in the case of recurrence of hepatocellular carcinoma.Even aged patients can successfully endure repeated hepatectomy using laparoscopy,as shown in the present report.This report presents a case of repeated laparoscopic hepatectomy treating hepatocellular carcinoma and its recurrence in an aged patient having cirrhosis,a disease causing extra difficulty for performing laparoscopic hepatectomy.The report also describes techniques of the operation and displays characteristic results of laparoscopic hepatectomy such as smaller wounds,less blood loss,less pain,less scars and adhesion,shorter postoperative hospital stay,and faster recovery. | Tan To Cheung Kelvin Kwok-chai Ng Ronnie Tung-ping Poon See Ching Chan Chung Mau Lo Sheung Tat Fan | 2010 | World Journal of Gastroenterology2010，16，4： | 5 |

| 12 | Drying kinetics of technical specified rubber显示文摘This paper reports the study of crumb rubber drying in different experimental designs.It is important to understand the characteristics of crumb rubber drying in order to formulate a better drying strategy that could give higher energy efficiency.Four experiments were carried out with constant heat at maximum 100℃ and a stainless steel container was used to hold the sample of crumb rubber under study.The surface temperature profile of the rubber was investigated using two types of drying methods,normal hot air drying and vacuum drying.It was found that when the sample was dried,external surface temperature for drying with hot air dryer was higher than vacuum dryer.The results showed the evolution of temperature profile was not in good agreement with the prediction which revealed that there was no temperature gradient within the drying samples.The energy consumption for vacuum drying was higher compared to hot air drying,where there was a difference of 0.7079 MJ/kg H2O evaporated for drying temperature at 100℃.The best fit model generated from the experimental data was the modified Henderson and Pabis model and the highest effective diffusivity obtained was 5.243×10^-9m^2/s heating by vacuum oven at 90℃ under zero atmospheric pressure. | Mei Xiang Ng Thing Chai Tham Sze Pheng Ong Chung Lim Law | 2015 | Information Processing in Agriculture2015，2，1： | 2 |
