OBJECTIVETo assess the feasibility of laparoscopic total mesorectal excision (TME) for low or ultralow anterior resection of rectal cancer.

METHODSExcision of the mesorectum and low (ultralow) colo-anal anastomoses were performed laparoscopically in 62 patients with low rectal cancer based on the concept of TME and double stapling technique (DST).

RESULTSSixty-two operations with TME and DST were performed in a totally laparoscopic manner, and only one was converted to open procedures because of dysfunction of coagulation. The operative time was 125 min (110-210 min) and the operative blood loss 20 ml (5-80 ml). The time for bowel function recovery and post-operatively dietary intake was 1-2 days. Twenty-eight patients received postoperative analgesics. Average hospital stay was 8 days (5-14 days). Complications were observed in only 2 of the 62 patients, one had suffered from urinary retention and the other, anastomotic leakage.

CONCLUSIONSTotally laparoscopic excision of the mesorectum for low or ultralow anterior resection of rectal cancer is a minimally invasive technique with sphincter preservation, less postoperative pain, and rapid recovery.

OBJECTIVETo observe the clinical efficacy differences between different needling methods for dry eye syndrome.

METHODSSixty patients of dry eye syndrome were randomly divided into an observation group and a control group, 30 cases (60 eyes) in each group. Shangjingming (Extra), Xiajingming (Extra), Tongziliao (GB 1), Cuanzhu (BL 2), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6), Taixi (KI 3) and Taichong (LR 3) were selected in the two groups. The control group was treated with conventional acupuncture, while the observation group was treated with guiding-acupuncture. Electroacupuncture (EA) was used at bilateral Tongziliao (GB1) and Cuanzhu (BL 2), 30 min per treatment. The treatment was given three times per week. Totally 1-month treatment (12 treatments) was given. The eye symptom score, breakup time of tear film (BUT), Schirmer Ⅰ test (SⅠT) and visual analogue scale (VAS) score were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSCompared before treatment, the eye symptom score, BUT, SⅠT and VAS score were improved after treatment in the two groups (all<0.001); the improvements of eye symptom score and SⅠT in the observation group were superior to those in the control group (both<0.05). The differences of BUT and VSA score between the two groups were not significant (both>0.05). The total effective rate was 86.7% (52/60) in the observation group, which was superior to 73.3% (44/60) in the control group (<0.05). .

CONCLUSIONThe conventional EA and guiding-acupuncture combined with EA are both effective for dry eye syndrome, and the efficacy of guiding-acupuncture combined with EA is superior to that of conventional EA.
