Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary.@*RESULTS@#A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001).@*CONCLUSIONS@#The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

Effects analysis between laparoscopic radical resection combined with radiofrequency ablation and open radical resection for colorectal liver metastases / 中华消化外科杂志

Objective To compare the clinical effects between laparoscopic radical resection combined with radiofrequency ablation (RFA) and open radical resection for colorectal liver metastases.Methods The retrospective cohort study was conducted.The clinicopathological data of 120 colorectal liver metastases patients who were admitted to the Mengchao Hepatobiliary Hospital of Fujian Medical University (80 patients) and the Third Mfiliated Hospital of Chongqing Medical University (40 patients) between September 2012 and April 2017 were collected.Sixty patients undergoing laparoscopic radical resection of colorectal cancer combined with RFA of liver metastases were allocated into the laparoscopy with RFA group,and 60 undergoing open radical resection of colorectal liver metastases were allocated into the open group.Observation indicators:(1) surgical and postoperative situations;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival up to May 2017.Measurement data with normal distribution were represented as x±s,and comparisons between groups were analyzed using independent-sample t test.Measurement data with skewed distribution were described as M (range).Comparisons of count data were analyzed using chi-square test or Fisher exact probability.The repeated measures data were analyzed using the repeated measures ANOVA.The survival curve and rate were respectively drawn and calculated by the Kaplan-Meier method,and the Log-rank test was used for survival analysis.Results (1) Surgical and postoperative situations:① All the patients underwent successful surgery,without conversion to open surgery in the laparoscopy with RFA group.Operation time,volume of intraoperative blood loss,cases with overall complications,death,abdominal pain,nausea and vomiting,liver dysfunction,pleural effusion,non-calculus cholecystitis and peptic ulcer and duration of postoperative hospital stay were respectively (135±34)minutes,(451±197)mL,31,0,18,6,6,4,3,2,(13±4)days in the laparoscopy with RFA group and (165±49)minutes,(794±204)mL,42,1,15,9,10,11,5,5,(19±4)days in the open group,with statistically significant differences in operation time,volume of intraoperative blood loss,cases with overall complications and duration of postoperative hospital stay between groups (t =3.983,9.394,x2 =4.232,t =9.148,P＜0.05),and no statistically significant differences in cases with death,abdominal pain,nausea and vomiting,liver dysfunction,pleural effusion,non-calculus cholecystitis and peptic ulcer between groups x2 =0.376,0.686,1.154,3.733,0.134,0.607,P＞0.05).() Levels of alanine aminotransferase (ALT),total bilirubin (TBil) and prothronbin time (PT) before operation,at day 1 and 3 postoperatively were respectively (70±9)U/L,(399±36)U/L,(231±19) U/L,(21±3) μmol/L,(26±3) μmol/L,(23±5) μmol/L,(17.3±2.4) seconds,(20.2-±4.4) seconds,(18.9±2.8) seconds in the laparoscopy with RFA group and (68± 8) U/L,(412±39)U/L,(253±22)U/L,(21±4)μmol/L,(28±4)μmol/L,(27±8)μmol/L,(16.6±3.0)seconds,(22.1±5.2) seconds,(20.1± 4.4)seconds in the open group,with statistically significant differences in the levels of ALT,TBil and PT before operation,at day 1 and 3 postoperatively between groups (F=16.727,13.115,4.194,P＜0.05).(2) Follow-up and survival situations:120 patients were followed up for 7-24 months,with a median time of 20 months.The postoperative 1-and 2-year tumor-free survival rates,1-and 2-year overall survival rates were respectively 23.3％,11.9％,85.0％,40.0％ in the laparoscopy with RFA group and 20.0％,12.8％,83.3％,38.3％ in the open group,with no statistically significant difference in above indicators between groups (x2 =0.145,0.069,0.012,0.196,P＞0.05).Further analysis showed that postoperative 2-year overall survival rate of patients with 1,2,3 and ＞3 liver metastasis lesions were respectively 53.3％,38.2％,40.0％,16.7％ in the laparoscopy with RFA group and 50.0％,35.7％,40.0％,15.4％ in the open group,with a statistically significant difference in 2-year survival rate of patients with different liver metastasis lesions in the laparoscopy with RFA group (x2 =20.949,P＜0.05) and in the open group (x2 ＝ 21.349,P＜0.05).Conclusion There are some advantages of fewer traumas,less complications,faster postoperative recovery and minimally invasive in laparoscopic radical resection combined with RFA for colorectal liver metastases,meanwhile,less liver metastasis lesions and better prognosis are found.

Robotic gastrectomy versus laparoscopic gastrectomy for gastric cancer: comparison of surgical performance and short-term outcomes.

PURPOSE: This study was designed to compare robot-assisted gastrectomy with laparoscopy-assisted gastrectomy in surgical performance and short-term clinical outcomes for gastric cancer and evaluate the safety and feasibility of robotic surgery. METHODS: A retrospective database of patients who underwent robotic or laparoscopic gastrectomy for gastric cancer between March 2010 and May 2013 was examined. After screening, 514 patients who underwent gastrectomy for gastric cancer were enrolled in this study: 120 robotic and 394 laparoscopic surgery. Patient demographics, surgical performance, and short-term clinical outcomes were examined. RESULTS: All operations were performed successfully. The clinicopathologic characteristics were similar between the two groups. Compared with the laparoscopic group, the robotic group had less intraoperative blood loss (118.3 ± 55.8 vs. 137.6 ± 61.6 ml, P < 0.001), more lymph nodes dissection (34.6 ± 10.9 vs. 32.7 ± 11.2, P = 0.013), and longer operation time (234.8 ± 42.4 vs. 221.3 ± 44.8 min, P = 0.003). The survival rates were 90.2% at 1 year, 78.1% at 2 years, and 67.8% at 3 years in the RAG group compared with 87.3% at 1 year, 77.1% at 2 years, and 69.9% at 3 years in the LAG group. The difference in overall survival rate between the two groups was not statistically significant (P = 0.812). In view of lymph node involvement, the 3-year survival rates for patients with negative nodal metastasis were 84.4% in the RAG group versus 82.6% in the LAG group (P = 0.972) and 57.5% in the RAG group versus 60.3% in the LADG group (P = 0.653) for those with positive nodal metastasis. CONCLUSIONS: Comparing well with laparoscopic gastrectomy, robot-assisted gastrectomy is a feasible and safe surgical procedure with clear operation field, precise dissection, minimal trauma, and fast recovery. Longer follow-up time and randomized, clinical trials are needed to evaluate the clinical benefits and long-term oncological outcomes of this new technology.

Effects of CO2 pneumoperitoneum pressures on growth and proliferation of gastric cancer cells in nude mice transplanted tumor / 中华普通外科杂志

Objective To investigate the effects of different CO2 pneumoperitoneum pressures on gastric cancer cells' growth and proliferation in nude mouse model of implanted tumor. Methods Human gastric cancer cell lines MNK-45 were exposed under 0、10、12 and 15 mm Hg CO2 pneumoperitoneum for 4 hrs respectively. 2 × 106 processed cells were inplanted into nude mice subcutaneously. Three weeks later, mice were sacrificed and the weight and bulk of the tumor measured. Then we observed the transplantation tumor by HE stain and Ki-67 stain. Results There was no significant difference in tumor's growing time, bulk and weight between 0, 10, 12 mm Hg CO2 pneumoperitoneum groups (7. 8 d, 7. 2 d, 7. 8 d; 1. 2 cm3, 1. 3 cm3, 1. 3 cm3; 1.5 g, 1. 9 g, 1. 6 g)and the control group (7. 3 d, 1. 2 cm3, 1.4 g) (P > 0. 05 ). The growing time of tumor in 15 mm Hg CO2 pneumoperitoneum (12. 5 d) was obviously longer than the control group ( P < 0.05 ) , the bulk and weight of tumor in 15 mm Hg CO2 pneumoperitoneum (0. 5 cm3, 0. 5 g) group significantly decreased compared with the control group (P <0.05). The positive rate of Ki-67 in 15 mm Hg CO2 pneumoperitoneum (27. 5% ) group was obviously lower than the control group (59.6%) (P<0.01). However, there were no significant differences between 0, 10, 12 mm Hg CO2 pneumoperitoneum groups (61.2%, 60.5%, 63.4%) and the control group (P > 0.05). Conclusion Clinically adopted CO2 pneumoperitoneum pressures have no significant effect on gastric cancer cells growth and proliferation.

Objective To investigate the change patterns of operation time of laparoscopic appendectomy and its significance. Methods The clinical data of 105 consecutive patients with appendicitis who received laparoscopic appendectomy at the Southwest Hospital from January 2007 to March 2010 were retrospectively analyzed. Of the 105 patients, five were converted to open surgery, and they were excluded from this study.The changes in operation time of different surgeons were statistically analyzed to detect the change patterns of the learning curve in laparoscopic appendectomy. Results A hundred cases of laparoscopic appendectomy were successfully performed by three surgeons. The mean operation time was ( 87 ± 36 ) minutes ( range, 30-217 minutes). No surgical injury happened during the operation, and the blood loss was under 10 ml. The learning curve of operation time was presented as a sine curve with an oscillating decreasing trend. The primary two cycles end at an average of 9.6 cases, which could be used as the end point of the learning curve of laparoscopic appendectomy. Conclusions The learning curve of laparoscopic appendectomy shows a typical oscillating decreasing trend. The preliminary study ends when 9.6 cases of operation are completed.

Application of Da Vinci surgical system in the treatment of gastric cancer / 中华消化外科杂志

With the development of instrumentation and surgical techniques,laparoscopic gastrectomy has become a promising surgical option for the treatment of gastric cancer.While laparoscopic gastrectomy is high technique-demanding,which hampered its popularization.Compared with traditional laparoscopes,Da Vinci surgical system has more special features,such as flexible robotic arms and three-dimensional imaging,which facilitates surgical procedures.A 58-year-old male patient with gastric cancer underwent Da Vinci surgical system-assisted radical total gastrectomy at the Southwest Hospital in March 2010.The mean operation time and blood loss were 270 minutes and 60 ml,respectively,and the number of dissected lymph nodes was 21.The short-term clinical effect was perfect without postoperative complications.Da Vinci surgical system-assisted radical total gastrectomy is safe and feasible,and it brings challenges to conventional laparoscopes.

Effects of HIF-1α on human gastric cancer cell's apoptosis in CO2 pneumoperitoneum environment / 中华普通外科杂志

Objective To study the effect and mechanism of human gastric cancer cell's apoptosis in simulated CO2 pneumoperitoneum environment by HIF-1α. Methods We used a closed box to simulate CO2 pneumoperitoneum environment, a standard surgical insufflator maintained pressure of the box at 0,5,10 and 15 mm Hg respectively. MKN-45 cell's HIF-1α mRNA and protein expression were observed before and after silencing cell's HIF-1α by real time RT-PCR and Western blot. Cell's bcl-2/bax was studied by immunohistochemistry before and after silencing HIF-1α. Cell's apoptosis ratio was measured using Annexin V-FITC/PI double labelled staining. Results In 15 mm Hg group, MKN-45 cell's HIF-1α mRNA and protein expression were significantly higher than control group (P<0.01 ), while the difference was not significant among 0,5,10 mm Hg group and control group (P>0.05). In 15 mm Hg CO2 pressure, cell's bcl-2/bax was obviously lower than in control group (P<0.05) and apoptosis ratio was more than control group(P<0.01). When HIF-1α was silenced, cell's bel-2/bax and apoptosis ratio weren't significantly different between 15 mm Hg group and control group (P>0.05 ). Conclusions MKN-45 cell's apoptosis did not experience any alterations under 0,5,10 mm Hg.15 mm Hg CO2 pneumoperitoneum environment enhanced cell's apoptosis probably by way of HIF-1α.
