Objective:To investigate the clinical efficacy of Da Vinci robotic assisted and laparos-copic assisted complete mesocolic excision (CME) for right hemicolon cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopatho-logical data of 119 patients with right hemicolon cancer who were admitted to Daping Hospital, Army Medical University from July 2016 to July 2019 were collected. There were 63 males and 56 females, aged (61±11)years. All the 119 patients underwent CME of right hemicolon. Of 119 patients, 37 cases undergoing Da Vinci robotic assisted CME of right hemicolon were divided into robotic group and 82 cases undergoing laparoscopic assisted CME of right hemicolon were divided into laparoscopic group. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups after propensity score matching; (2)intraoperative and postoperative situations; (3) postoperative pathological examination; (4)follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect tumor metastasis and survival of patients after surgery up to August 2019. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Count data were represented as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to calculate survival rate and the GraphPad Prism 5 software was used to draw survival curve. The Log-rank test was used for survival analysis. Results:(1) The propensity score matching conditions and comparison of general data between the two groups after propensity score matching: 68 of 119 patients had successful matching, including 34 cases in each group. Before propensity score matching, cases undergoing surgery by surgeon A or surgeon B were 32, 5 of the robotic group, versus 49, 33 of the laparoscopic group, showing a significant difference between the two groups ( χ2=8.381, P<0.05). After propensity score matching, the gender (males or females), age, body mass index (BMI), cases with tumor classified as stageⅠ, stage Ⅱ or stage Ⅲ of TNM staging, cases with tumor located at ileocecal region, ascending colon, hepatic flexor of colon or transverse colon, cases undergoing surgery by surgeon A or surgeon B were 17, 17, (62±10)years, (22.4±2.7)kg/m 2, 4, 14, 16, 3, 15, 10, 6, 29, 5 of the robotic group, versus 15, 19, (62±11)years, (22.4±2.8)kg/m 2, 4, 18, 12, 2, 19, 7, 6, 30, 4 of the laparoscopic group, showing no significant difference between the two groups ( χ2=0.236, t=0.127, 0.044, χ2=1.071, 1.200, 0.000, P>0.05). (2) Intraoperative and postoperative situations: after propensity score matching, the operation time, volume of intraoperative blood loss, cases undergoing conversion to open surgery, time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative initial liquid food intake, duration of postoperative hospital stay and treatment expenses were (235±50)minutes, (73±45)mL, 0, (1.9±0.7)days, (2.9±1.2)days, (3.1±2.4)days, (9.1±4.9)days, (9.6±1.8)×10 4 yuan of the robotic group, versus (183±35)minutes, (74±74)mL, 1, (2.1±0.6)days, (3.3±1.4)days, (3.5±4.2)days, (9.1±3.9)days, (6.3±1.6)×10 4 yuan of the laparoscopic group, respectively. There were significant differences in the operation time and treatment expenses between the two groups ( t=5.050, 8.165, P<0.05) while there was no significant difference in the volume of intraoperative blood loss, time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative initial liquid food intake or duration of postoperative hospital stay between the two groups ( t=0.118, ?0.462, ?1.129, ?1.291, 0.027, P>0.05). There was no significant difference in the conversion to open surgery between the two groups ( P>0.05). Five patients of the robotic group and 7 patients of the laparoscopic group had postoperative complications. There was no significant difference in the postoperative complications between the two groups ( χ2=0.405, P>0.05). (3) Postoperative pathological examination: after propensity score matching, cases with R 0 resection, the number of lymph node dissected, cases with lymph node metastasis and cases with tumor differentiation as well differentiated adenocarcinoma, moderately differentiated adeno-carcinoma, poorly differentiated adenocarcinoma or mucinous adenocarcinoma were 34, 17±5, 14, 1, 22, 6, 5 of the robotic group, versus 34, 17±5, 12, 2,20, 2, 10 of the laparoscopic group, respectively. There was no significant difference in the R 0 resection between the two groups ( P>0.05) and there was no significant difference in the number of lymph node dissected, lymph node metastasis and tumor differentiation between the two groups ( t=0.488, χ2=0.249, 4.095, P>0.05). (4) Follow-up: after propensity score matching, 68 patients were followed up for 1?36 months, with a median follow-up time of 24 months. The follow-up time was (20±13)months of the robotic group, versus (21±13)months of the laparoscopic group, showing no significant difference between the two groups ( t=0.409, P>0.05). During the follow-up, 3 cases of the robotic group and 4 cases of the laparoscopic group had tumor distant metastasis. The disease-free survival rate and overall survival rate at postoperative 3 years were 83.9% and 86.8% of the robotic group, versus 82.0% and 86.6% of the laparoscopic group, showing no significant difference between the two groups ( χ2=0.188, 0.193, P>0.05). Conclusion:Da Vinci robotic assisted CME for right hemicolon cancer is safe and feasible.

Enhanced recovery after surgery (ERAS) has been widely used in the world for near 20 years, which should be considered as the milestone of modern medicine advancement, changing the routine perioperative principle, accelerating the recovery speed following operation, minimizing the postoperative pain, and saving the medical resources. Despite the remarkable advance, the quality and application of ERAS in the west China needs further improvement if compared with international level or even some domestic hospitals. The postoperative hospital stay in west China is much longer than the reported 3 to 5 days according to published references. Several suggestions can be help: (1) Based on the published consensus and the successful experiences of ERAS in colorectal surgery, the medical institution should make great effort to extend this technique to change the profound traditional idea in medical staffs and patients. (2) The medical administrations should take the application of ERAS as a key performance index and annual work plan in hospital. (3) Multiple disciplinary team including anesthetist, surgeon, dietitian, and nurses is essential for hospital to promote the quality of ERAS. Undoubtedly, ERAS is going to be the conventional medical care in the western area of China. We may look forward to seeing more researches from western China to update the ERAS consensus.

OBJECTIVETo explore the feasibility and safety of transanal minimal invasive or combined laparoscopy total mesorectal excision.
METHODSClinical data of 11 cases with rectal cancer undergoing transanal total mesorectal excision(taTME) in our hospital between September 2014 and May 2015 were analyzed retrospectively.
RESULTSAmong 11 patients, 3 underwent pure-taTME successfully without abdominal incision and ileostomy, whose operation time was 210, 230, 215 min respectively, while other 8 patients underwent laparoscopy-assisted taTME(hybrid-taTME) with operation time ranging from 150 to 290 (median 205) min. No patient was transferred to open operation, while larger tumors of two patients were removed from hypogastric 5 cm incision. Postoperative first day VAS score was 1 to 3(2.0±0.6), the first flatus was 6 to 70(30.2±17.3) h, hospital stay was 4 to 12(7.5±2.5) d, the blood loss was (104±127) ml and the liquid food intake was (28.3±6.3) h. Postoperative complications included 1 case of subcutaneous emphysema, 1 case of anastomotic stoma bleeding, 2 cases of dysuria, which were cured by conservative therapy. One patient developed rectovaginal fistula 20 days after operation and then underwent ileostomy. No relapse of tumor or death during follow-up.
CONCLUSIONSFor suitable rectal cancer patients, taTME or hybrid-taTME is feasible.

OBJECTIVE: To retrospectively evaluate the short-term outcomes and safety of computed tomography (CT)-guided percutaneous microwave ablation (MWA) of solitary adrenal metastasis from lung cancer. MATERIALS AND METHODS: From May 2010 to April 2014, 31 patients with unilateral adrenal metastasis from lung cancer who were treated with CT-guided percutaneous MWA were enrolled. This study was conducted with approval from local Institutional Review Board. Clinical outcomes and complications of MWA were assessed. RESULTS: Their tumors ranged from 1.5 to 5.4 cm in diameter. After a median follow-up period of 11.1 months, primary efficacy rate was 90.3% (28/31). Local tumor progression was detected in 7 (22.6%) of 31 cases. Their median overall survival time was 12 months. The 1-year overall survival rate was 44.3%. Median local tumor progression-free survival time was 9 months. Local tumor progression-free survival rate was 77.4%. Of 36 MWA sessions, two (5.6%) had major complications (hypertensive crisis). CONCLUSION: CT-guided percutaneous MWA may be fairly safe and effective for treating solitary adrenal metastasis from lung cancer.

Robotic-assisted transanal total mesorectal excision (R-TaTME) has unique advantage in low rectal cancer. Single incision plus oneport (SIPOP) laparoscopic operation can synchronously cooperate with robotic-assisted transanal operation, in order to the difficulty of operation, improve the quality of operation and shorten the time of operation. A retrospective analysis was conducted on the clinical and pathological data of one patient who underwent SIPOP synchronously combined with R-TaTME + sigmoid-anal anastomosis + ileostomy at the Department of General Surgery, Army Characteristic Medical Center on September 11, 2019. This 71-year-old patient was male with body mass index of 24.08 kg/m 2 and received preoperative chemotherapy. Rectal adenocarcinoma was confirmed by colonoscopy biopsy, and distance from tumor lower edge to anal verge was 3 cm. MRI indicated T2N1 stage. The operation was completed successfully, and the transabdominal and robotic transanal surgery totaled 117 minutes, with 15 minutes for the robotic transanal preparation step. There was about 20 ml of intraoperative blood loss and no blood transfusion was performed. The patient was discharged 6 days after operation. No intraoperative or postoperative complications occurred. The postoperative TNM staging was stage I (pyT2N0cM0). No recurrence or metastasis was found at postoperative 7 month. It is a safe, effective and feasible technique for patients with low rectal cancer.
