AIM:To evaluate the role and outcome of conventional surgery in the treatment of pyogenic liver abscess in the modern era of minimally invasive therapy. METHODS:The medical records of thirteen patients with pyogenic liver abscess who underwent surgical treatment between January 1995 and December 2002 were retrospectively reviewed to determine the clinical presentation, indication and nature of surgery, and out-come of surgery. RESULTS:The patients were predominantly women (10/13) with a mean age of 65 ± 17 years. Their main presenting symptoms were abdominal pain (100%) and fever (77%). The aetiologies included biliary (n = 6), cryptogenic (n = 3), portal (n = 2), and trauma (n = 2). Seven patients underwent percutaneous drainage as the initial treatment. Of these, three patients developed peritonitis secondary to peritoneal spillage. Another four patients failed to respond because of multilocula-tion. Salvage surgery was required in these patients. Six patients proceeded to straight laparotomy:two had marked sepsis and multiloculated abscess that precluded percutaneous drainage, and four presented with perito-nitis of uncertain pathology. Surgical procedures included deroofment and drainage (n = 9), liver resection (n = 3), peritoneal lavage (n = 2), cholecystectomy (n = 4), and exploration of common bile duct (n = 2). One patient required reoperation because of bleeding. Three patients required further percutaneous drainage after surgery. The overall mortality was 46%. Four patients died of multiorgan failure and two patients died of pulmonary embolism. CONCLUSION:Surgical treatment of pyogenic liver ab-scess is occasionally needed when percutaneous drainage has failed due to various reasons. Mortality rate in this group of patients has remained high.

Ever since its earliest reports, portal venous gas (PVG) has been associated with numerous intraabdominal catastrophes and has served as an indication for urgent surgical exploration. It is traditionally regarded to be an ominous finding of impending death, with highest mortality reported in patients with underlying bowel ischemia. Today, computed tomography has demonstrated a wider range of clinical conditions associated with PVG, some of which are ‘benign’ and do not necessarily require surgery, unless when there are signs of intraabdominal catastrophe or systemic toxicity. One of these ‘benign’ conditions is Crohn’s disease. The present report describes a 19-year-old Chinese boy with Crohn’s pancolitis who presented with septic shock associated with PVG and portal vein thrombosis, and was successfully managed surgically. To our knowledge, this is the fi rst report of PVG and portal vein thrombosis associated with Crohn’s disease in a Chinese patient. In addition, we have also reviewed the reports of another 18 Crohn’s patients with PVG previously described in the English literature. Specifi c predisposing factors for PVG were identified in 8 patients, including barium enema, colonoscopy, blunt abdominal trauma, and enterovenous f istula. The patients who developed PVG following barium enema and blunt trauma were all asymptomatic and no specifi c treatment was necessary. Eleven patients (58%) who presented with signs of intraabdominal catastrophe or systemic toxicity required either immediate or eventual surgery. The overall mortality rate among the 19 patients was only 11%. The present literature review has shown that the f inding of PVG associated with Crohn’ s disease does not always mandate surgical intervention. It is the clinical features and the related complications that ultimately determine the treatment approaches. The overall outcome of PVG associated with Crohn’s disease has been favourable.

Telerobotic surgery is the most advanced development in the field of minimally invasive surgery. The da Vinci surgical system, which is currently the most widely used telerobotic device, was approved by the Food and Drug Administration of the United States of America for clinical use in all abdominal operations in July 2000. The first da Vinci surgical system in China was installed in November 2005 at our institution. We herein report the first telerobotic-assisted laparoscopic abdominoperineal resection using the 3-arm da Vinci surgical system for low rectal cancer in Hong Kong and China, which was performed in August 2006. The operative time and blood loss were 240 min and 200 mL, respectively. There was no complication, and the patient was discharged on postoperative day five. An updated review of published literature on telerobotic-assisted colorectal surgery is included in this report, with special emphasis on its advantages and limitations.

Hepatic venous outflow obstruction after piggyback liver transplantation is a very rare complication. An unusual mechanism aggravating it is reported. A 33-year-old man with end-stage hepatitis B liver cirrhosis underwent a piggyback orthotopic liver transplantation using a full-size cadaveric graft. Two months after transplantation, he developed gross ascites refractory to maximal diuretic therapy. Doppler ultrasound showed patent portal and hepatic veins. Serial computed tomography scans revealed a hypoperfused right posterior segment of the liver which subsequently underwent atrophy. Hepatic venography demonstrated a high-grade stenosis with an element of torsion of venous drainage at the anastomosis. The stenosis was successfully treated with repeated percutaneous balloon angioplasty. The patient remained asymptomatic six months afterwards with complete resolution of ascites and peripheral edema. We postulate that liver allograft segmental hypoperfusion and atrophy may aggravate or result in a hepatic venous outflow problem by the mechanism of torsion effect. Percutaneous balloon angioplasty is a safe and effective treatment modality for anastomotic stenosis.

In Chinese societies, traditional Chinese medical clinics are popular and play a significant role in primary healthcare. The current study aimed to examine the mental health of new patients at Chinese medical clinic. A cross-sectional questionnaire survey was conducted. Subjects were new patients of a Chinese medical clinic recruited through 100% consecutive sampling during a 5-week period. A response rate of 84.2% and a sample size of 367 were achieved. Sample included 111 (30.2%) men and 256 (69.8%) women. Mean age was 44.0 (SD = 17.1). Presenting problems were all somatic, with 68.3% lasted over 1 month and 37.1% lasted over 1 year. In the month prior to first consultation, 26.4%, 33.2% and 19.3% patients consulted other public, private and Chinese medical clinic on average 1.5, 1.9 and 3.0 times respectively. Besides, 7.4% and 6.5% patients self-administered Western and Chinese drugs on average 1.3 and 2.4 times respectively. Using a cut-off of ? 5 on GHQ-12, prevalence of common mental disorders was estimated at 21.0%. In conclusion, findings revealed that common mental disorders were prevalent among new Chinese medicine patients al-though presenting problems of subjects were all somatic. many of these presenting medical conditions were chronic, with 68.3% lasting over 1 month and 37.1% lasting over 1 year. Over 70% patients had been seek-ing various forms of treatment in the month prior to first consultation. Mental health and illness behavior of Chinese medicine patients warrants further research and attention.

AIM: To compare quality of life (QoL) outcomes in Chinese patients after curative laparoscopic vs open surgery for rectal cancer. METHODS: Eligible Chinese patients with rectal cancer undergoing curative laparoscopic or open sphincterpreserving resection between July 2006 and July 2008 were enrolled in this prospective study. The QoL outcomes were assessed longitudinally using the validated Chinese versions of the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQCR38 questionnaires before surgery and at 4, 8, and 12 mo after surgery. The QoL scores at the different time points were compared between the laparoscopic and open groups. A higher score on a functional scale indicated better functioning, whereas a higher score on a symptom scale indicated a higher degree of ***: Seventy-four patients (49 laparoscopic and 25 open) were enrolled. The two groups of patients were comparable in terms of sociodemographic data, types of surgery, tumor staging, and baseline mean QoL scores. There was no significant decrease from baseline in global QoL for the laparoscopic group at different time points, whereas the global QoL was worse compared to baseline beginning at 4 mo but returned to baseline by 12 mo for the open group (P = 0.019, Friedman test). Compared to the open group, the laparoscopic group had significantly better physical (89.9±1.4 vs 79.2±3.7, P = 0.016), role (85.0±3.4 vs 63.3±6.9, P = 0.005), and cognitive (73.5±3.4 vs 50.7±6.2, P = 0.002) functioning at 8 mo, fewer micturition problems at 4-8 mo (4 mo: 32.3±4.7 vs 54.7±7.1, P = 0.011; 8 mo: 22.8±4.0 vs 40.7±6.9, P = 0.020), and fewer male sexual problems from 8 mo onward (20.0±8.5 vs 76.7±14.5, P = 0.013). At 12 mo after surgery, no significant differences were observed in any functional or symptom scale between the two groups, with the exception of male sexual problems, which remained worse in the open group (29.2±11.3 vs 80.0±9.7, P = 0.026). CONCLUSION: Laparoscopic sphin

AIM: To give a comprehensive review of current litera-ture on robotic rectal cancer ***: 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 *** 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.

目的:以结构性问卷对社区成年人进行郁证流行病学调查。方法:以整群抽样的形式对755名香港成年人采用横断面的方法进行结构性问卷调查。结果:以症状严重程度的自我评估为参考,受试者工作特征的分析结果显示,50分为郁证量表的最佳诊断分界点,其中,假阳性和假阴性值分别为25.8%和23.3%。郁证的患病率为6.2%,其中,女性患病率较男性高,男女之比为1:2.8(P=0.02)。郁证与年龄呈显著负相关关系(r=-0.22,P<0.01),但与婚姻状况、教育程度以及个人收入无显著相关关系。在郁证患者中,30.4%的患者表现出有极大的意愿去寻求治疗(男性为25.0%,女性为32.4%)。结论:郁证在成年人中颇为普遍,且患者有较高的寻求治疗的意愿。由此可见,此概念可以作为干预治疗的一个切入点,值得作更进一步的研究。本文分析了采用结构性问卷进行流行病学研究的局限性并提出了相应的改善措施。
