Objective To study the feasibility and clinical effect of trans umbilical single incision laparoscopic right hemicolectomy for right hemicolon carcinoma.Methods The clinical data of 35 patients with right hemicolon carcinoma were retrospectively analyzed,the 15 cases were received the trans umbilical single incision laparoscopic right hemicolectomy (single incision group) and 20 cases were received laparotomy right hemicolectomy (laparotomy group).The clinical indexes were compared between the 2 groups.Results The length of incision,intraoperative bleeding volume,passage of gas by anus time,feeding time,hospitalized time in single incision group were significantly better than those in laparotomy group [(5.5 ± 0.6) cm vs.(17.6 ± 2.2) cm,(84.0 ± 31.1) ml vs.(155.5 ± 43.1) ml,(2.00 ± 0.76) d vs.(3.75 ± 0.63) d,(5.3 ± 0.6) d vs.(6.5 ± 0.6) d,(9.3 ± 1.4) d vs.(13.5 ± 1.5) d],the operation time in single incision group was significantly longer than that in laparotomy group [(238.4 ± 19.3) min vs.(165.3 ± 25.8) min],there were statistical differences (P < 0.05).There was no statistical difference in number of incision lymph node between the 2 groups (P > 0.05).Postoperative complication in single incision group occurred in 2 cases,postoperative complication in laparotomy group occurred in 3 cases,there was no statistical difference (P >0.05).The follow-up time was 1-55 months,the median follow-up time was 28 months,local recurrence and distant metastasis were found in 2 cases in single incision group,and 4 cases was found in laparotomy group,there was no statistical difference (P > 0.05).Conclusions Single incision laparoscopic right hemicolectomy for right hemicolon carcinoma is safe and feasible,which has the advantages of minimal trauma,aesthetic outlook,less bleeding,quick recovery and short hospitalization time,etc.It can be developed in the hospital which has some basis of laparoscopic surgery.

OBJECTIVETo explore the effect of arterial infusion with methylene blue during total mesorectal excision (TME) for better preservation of pelvic autonomic nerve on urination function and sexual function in male patients with rectal cancer.
METHODSA total of 68 male rectal cancer patients from Zhejiang Xiaoxing People's Hospital and 44 male rectal cancer patients from Guangdong Zhongshan Chenxinghai Hospital between June 2013 and June 2015 were prospectively enrolled. Patients were randomly divided into the trial group receiving arterial infusion with 8 ml of 1% methylene blue and the control group without artery infusion, with 56 cases in each group. All the patients underwent TME. Intra-operational lymph node removal and postoperative urination and sexual function (erection and ejaculation) were compared between two groups.
RESULTSThe baseline data of the two groups were not significantly different (all P>0.05). As compared to the control group, the trial group had shorter operation time [(3.28±0.63) hours vs. (4.01±0.94) hours, P<0.01], less blood loss[(92.5±36.4) ml vs. (174.1±61.4) ml, P<0.01], and more lymph nodes harvested per patient (15.8±7.6 vs. 11.9±4.3, P<0.01). One year after operation, classI(, II(, III(, IIII( of urination was observed in 33 cases (58.9%), 15 cases (26.8%), 6 cases (10.7%), 2 cases (3.6%) in the trial group, while 24 (42.9%), 15 (26.8%), 12 (21.4%), 5 (8.9%) in the control group, which indicated that trial group was superior to control group(P<0.05). ClassI(, II(, III( of erection was observed in 36 cases (64.3%), 18 cases (32.1%), 2 cases(3.6%) in the trial group, while 25(44.6%), 23(41.1%), 8(14.3%) in the control group, which indicated that trial group was superior to the control group (P<0.05). ClassI(, II(, III( of ejaculation was found in 36 cases (62.5%), 18 cases (32.1%), 3 cases (5.4%) in the trial group, while 24 (42.9%), 22 (39.3%), 10(17.9%) in the control group, which also indicated that trial group was superior to the control group(P<0.05).
CONCLUSIONSIn the treatment of male rectal cancer patients, TME combined with arterial infusion with methylene blue can facilitate the distinction of operation scope, which is beneficial to reduce damages to the pelvic nerve, leading to the protection of urinary function and sexual function. In addition, this procedure can result in shorter operation time, less operational blood loss and more lymph nodes harvested.

Objective To investigate the clinical value of multidisclplinary team (MDT) in the application of non-small cell lung cancer (NSCLC). Methods We retrospectively analyzed the postoperative clinical data of 80 patients with NSCLC in the First Hospital of Lanzhou University between January 2014 and May 2018. There were 56 males, 24 females at age of 59±10 years. Forty five patients were performed lobectomy with conventional model, 35 patients were also performed lobectomy after MDT discussion. The clinical effect of the two groups was compared. Results Compared to conventional model, MDT can shorten operation time, intraoperative blood loss, postoperative chest drainage, catheterization time, complications, length of stay and hospital costs. But there was no significant difference in intraoperative transthoracotomy proportion, delayed wound healing and postoperative pulmonary leakage between the two groups. Conclusion The efficacy of MDT in the surgical treatment of NSCLC is satisfactory. The MDT is valuable during operation, which reduces surgical trauma and accelerate patients’ recovery, and deserves the clinical promotion.

Objective To evaluate the efficacy of tubless therapy for pulmonary bulla resection under the concept of fast track surgery. Methods We retrospectively analyzed the clinical data of 45 patients (29 males and 16 females at an average age of 26.1 years) with pulmonary bullae in our hospital between January 2015 and December 2017. These patients were divided into two groups. Among them, 25 patients were treated with preoperative gastric tubes and catheters, tracheal intubation anesthesia and postoperative drainage tubes (a tube group). And 20 patients were treated with no preoperative gastric tube or catheter, sublaryngeal anesthesia and no postoperative drainage tube (a tubless group). Results There was a statistical difference in postoperative pain index (2.60±1.14 vs. 5.16±1.24, P<0.001) and larynx complication (P=0.00) between the two groups. Shorter period of epidural analgesic tubes (1.40±0.50 d vs. 2.84±0.75 d, P<0.001), shorter operation and anesthesia time (15.00±2.59 min vs. 18.56±2.10 min, P<0.001; 95.30±4.38 min vs. 105.50±4.59 min, P<0.001), shorter hospital stay (9.45±1.66 d vs. 12.80±1.87 d, P<0.001), and less expense (20 245.96±1 113.02 yuan vs. 22 147.06±1 735.01 yuan, P<0.001) in the tubless group were found compared with the tube group. But there was no statistical difference in incidence of complication of lung (P=0.43) between the two groups. Conclusion Tubless therapy in the treatment of pulmonary bulla resection can accelerate the postoperative recovery with shorter hospital stay and less expense, and is an advantageous treatment.

Objective To discuss the safety, feasibility and advantages of tubeless trans-subxiphoid thoracoscopic surgery in anterior mediastinal tumor resection. Methods A total of 32 patients suffering anterior mediastinal tumor were enrolled, including 17 patients (8 males and 9 females) with average age of 31.8±8.4 years who had been performed tubeless trans-subxipohoid tharcoscopic surgery and 15 patients (8 males and 7 females) with average age of 31.1±9.2 years who had been performed traditional trans-subxipohoid tharcoscopic surgery. The differences of surgical duration, the lowest intraoperative arterial oxygen saturation (SaO2), postoperative awaking time, postoperative pain visual analogue score (VAS), postoperative pulmonary recruitment time, duration of postoperative hospital stay and hospitalization cost were analyzed. Results Postoperative awaking time (18.5±1.8 min vs. 28.9±4.2 min, P=0.000), postoperative VAS (1.6±0.6 vs. 3.5±7.4, P=0.000), duration of postoperative hospital stay (2.5±7.2 d vs. 4.3±1.1 d, P=0.000) and hospitalization cost (3.2±1.1 ten thousand RMB vs. 4.9±1.1 10 ten thousand RMB, P=0.000) in the tubeless group were better than those in the control group. There was no significant difference in surgical duration (51.7±6.5 min vs. 55.1±8.5 min), the lowest intraoperative SaO2 (98.5%±0.9% vs. 98.1%±0.8%), postoperative pulmonary recruitment time (33.9±12.2 d vs. 38.4±15.2 d, P>0.05) between the two groups. Conclusion Tubeless trans-subxiphoid thoracoscopic surgery is safe, feasible and advanced in anterior mediastinal tumor resection.
