Hand-assisted laparoscopic versus open right hemicolectomy: short-term outcomes in a single institution from China.
ABSTRACT To compare the perioperative parameters and short-term outcomes of hand-assisted laparoscopic colectomy (HALC) and open colectomy (OC) for the treatment of patients with cancer of the right hemicolon.
Patients who were scheduled to perform right hemicolectomy between August 2009 and December 2010 were randomized into either HALC or OC group. Patients were excluded if they had synchronous cancers, hepatic metastases, acute intestinal obstruction, or intestinal perforations. All the operations in the 2 groups were performed by a single surgical team. Measured outcomes included the demographic variables and perioperative parameters. The former included age, sex, body mass index, American Society of Anesthesiologists class, prior abdominal surgery, distribution of tumors, and histopathologic stage; whereas the latter included length of incision, operative time, estimated blood loss, conversion rate, number of lymph nodes retrieved, postoperative pain score, time to return of bowel function, postoperative complications, duration of hospital stay, and total cost.
One hundred sixteen patients with cancer of the right hemicolon (HALC=59, OC=57) were recruited. The 2 groups of patients were similar in age, sex distribution, body mass index, American Society of Anesthesiologists class, and previous abdominal surgery. No significant difference was observed between the 2 groups in terms of distribution of tumors and the final histopathologic staging. HALC had a significantly shorter incision length and longer operative time than OC. Patients in the HALC group had significantly less operative blood loss, less pain and earlier passage of flatus after operation than those in the OC group. The number of lymph nodes recovered in the specimen and the overall postoperative complications was comparable in the 2 groups. The postoperative duration of hospital stay was significantly shorter in the HALC group, whereas the median overall costs in the HALC group were significantly higher than that in the OC group.
The results from the present study demonstrate that the HALC is a valid surgical approach for cancer of the right hemicolon that retains the benefits of minimally invasive surgery. We believe that this technique is a safe, useful, and feasible method for patients with right-sided colonic cancer. If practiced more, it might be advocated as a "bridge" between traditional laparoscopic surgery and conventional open procedures.

ABSTRACT: The present study aimed to compare the results of handassisted laparoscopic surgery (HALS) and conventional laparotomy (CL) at a single institution in Japan. Of the 212 patients with stage I/II/III colorectal cancer who received a curative resection, 98 patients underwent HALS and 114 patients underwent CL. The clinical background and postoperative management did not differ between the two groups. There were no significant differences in the 3year relapsefree and 3year overall survival rates between the HALS and CL groups for the patients in any stage. Blood loss during surgery was 250.1 and 135.5 ml (mean and median; the same hereafter) in stage I patients receiving HALS versus 608.2 and 315.5 ml in stage I CL patients (P=0.006), while it was 277.6 and 146 ml in stage II patients receiving HALS versus 548.6 and 347 ml in stage II CL patients (P=0.004). Postoperative hospital stay was recorded at 16.8 and 15 days in stage III patients receiving HALS versus 23.1 and 21 days in stage III CL patients (P=0.001). There were no significant differences in the operating time or complications between the two groups. These results indicate that the survival rate was comparable for HALS and CL, while HALS caused less surgical stress and achieved a better cosmetic outcome. The results of the final analysis of this cohort are awaited.Oncology letters 08/2014; 8(2). DOI:10.3892/ol.2014.2182 · 0.99 Impact Factor

ABSTRACT: The objective of this study is to identify and review the methodological quality of health economic evaluations of medical devices performed in the People's Republic of China. To our knowledge, no such investigations have been performed to date. A systematic literature review involving searches of Medline, Medline In-Process, the National Health Service Economic Evaluation Database, the Cost-Effectiveness Analysis Registry of the Tufts Medical Center, and the Wanfang Database was performed. The search spanned the period from 1990 to 2013. Studies on health economic evaluations of medical devices, in-vitro diagnostics, procedures, and the use of medical devices in Chinese health care settings were included. Full-text articles and conference abstracts in English and Chinese were included. Fifty-seven publications were included, 26 (46%) of which were in English and 31 (54%) of which were in Chinese. The included publications covered a wide range of clinical areas, such as surgery (n=23, 40%), screening (n=9, 16%), imaging use (n=6, 11%), kidney intervention (n=4, 7%), and nine other technological areas. Most of the studies (n=31, 54%) were cost analyses. Among the others, 13 (50%) studies used modeling, and another 13 (50%) were within-trial evaluations. Among studies that used modeling, eleven (85%) conducted sensitivity analyses, six of which had one-way sensitivity analysis, whereas one conducted both one-way and two-way sensitivity analyses; four of these eleven modeling-based analyses included probabilistic sensitivity analyses. The incremental cost-effectiveness ratio was reported in ten (18%) studies, eight of which were screening studies. The remaining two modeling studies were in areas of imaging and oncology. This study indicates that there are major limitations and deficiencies in the health economic evaluations on medical devices performed in the People's Republic of China. Further efforts are required from different stakeholders - academic, governmental, and privatized - to improve health economic research capacity and to put it to use when informative decisions are made in the health care setting.ClinicoEconomics and Outcomes Research 01/2015; 7:195-204.

ABSTRACT: To describe the learning curves of hand-assisted laparoscopic D2 radical gastrectomy (HALG) for the treatment of gastric cancer. The HALG surgical procedure consists of three stages: surgery under direct vision via the port for hand assistance, hand-assisted laparoscopic surgery, and gastrointestinal tract reconstruction. According to the order of the date of surgery, patients were divided into 6 groups (A-F) with 20 cases in each group. All surgeries were performed by the same group of surgeons. We performed a comprehensive and in-depth retrospective comparative analysis of the clinical data of all patients, with the clinical data including general patient information and intraoperative and postoperative observation indicators. There were no differences in the basic information among the patient groups (P > 0.05). The operative time of the hand-assisted surgery stage in group A was 8-10 min longer than the other groups, with the difference being statistically significant (P = 0.01). There were no differences in total operative time between the groups (P = 0.30). Postoperative intestinal function recovery time in group A was longer than that of other groups (P = 0.02). Lengths of hospital stay and surgical quality indicators (such as intraoperative blood loss, numbers of detected lymph nodes, intraoperative side injury, postoperative complications, reoperation rate, and readmission rate 30 d after surgery) were not significantly different among the groups. HALG is a surgical procedure that can be easily mastered, with a learning curve closely related to the operative time of the hand-assisted laparoscopic surgery stage.
