ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the feasibility and efficacy of Zhu's trocar placement (ZTP) in laparoscopic appendectomy (LA) in the treatment of complicated appendicitis.</p><p><b>METHODS</b>Clinical data of 139 complicated appendicitis patients undergoing LA at the First Affiliated Hospital of Wenzhou Medical University from June 2013 to December 2017 were retrospectively analyzed. ZTP-LA group comprised 59 cases and its procedure was as follows: 10 mm umbilical trocar was used as lens port; 12 mm trocar at crossing point of umbilical hole horizontal line and right midclavicular line was used as main operating port; 5 mm trocar at the crossing point of horizontal line 0-3 cm below umbilicus and right anterior axillary line was used as assist operating port with the drainage function for Douglas fossa and right iliac fossa; The operator and the assistant stood on the right side and the left side of the patient respectively. Traditional three-port group comprised 80 cases (8 cases converted to laparotomy, 72 cases enrolled finally) and its procedure was as follows: 10 mm lens port below umbilicus; 10-12 mm main operating port at lateral border of left lower rectus abdominis; 5 mm assist operating port above pubis; The operator and the assistant stood on left side of the patient. The operative time, time to oral semi-fluid, postoperative hospital stay, cost during hospitalization, and postoperative morbidity of complication were compared between two groups.</p><p><b>RESULTS</b>Baseline data such as gender, age, WBC count, percentage of leukocyte, pathological finding and type were not significantly different between two groups(all P>0.05). The conversion rate in ZTP-LA was significantly lower than that in traditional three-port group [0%(0/59) vs. 10.0%(8/80),χ²=4.552,P=0.033]. Compared with traditional three-port group, ZTP-LA group showed shorter operative time [(47.8±20.1) minutes vs. (66.0±27.3) minutes, t=4.383,P<0.001], shorter time to oral semi-fluid [(35.0±20.7) hours vs. (59.3±32.8) hours, t=5.158,P<0.001], shorter postoperative hospital stay [(4.1±1.6) days vs. (5.5±2.2) days, t=4.162, P<0.001], lower postoperative morbidity of complication [3.4% (2/59) vs. 18.1%(13/72), χ²=6.879, P=0.009], lower incidence of postoperative intra-abdominal abscess [0%(0/59) vs. 11.1%(8/72), χ²=5.179, P=0.023], lower incidence of paralytic ileus [1.7%(1/59) vs. 12.5%(9/72), χ²=3.946, P=0.047] and less cost during hospitalization[(13 585±2909) yuan vs.(16 861±5334) yuan, t=4.463, P<0.001].</p><p><b>CONCLUSION</b>ZTP-LA is safe, feasible and effective with advantages of faster recovery and less cost in the treatment of complicated appendicitis.</p>

Objective To evaluate extended vs standard left lateral lobectomy for left lateral lobe hepatolithiasis.Methods A retrospective study was conducted on the clinical data of 110 patients who underwent hepatectomy for hepatolithiasis limited to left lateral lobe of the liver.Results 42 patients received left lateral lobectomy, 68 patients did left hemihepatectomy.There were no marked difference between the two groups in the operation time, introperation or postoperation blood loss, bile leak and bleeding on the hepatic cut surface, liver function and the postoperative hospital stay.The incidence of residual and recurrent stones was 14.3％ and 11.9％ in left lateral lobectimy group and 0％, 0％ in left hemihepatectomy group.Conclusion Left hemihepatectomy for left lateral lobe hepatolithiasis is a safe and effective procedure.
ABSTRACT
Objective To evaluate effects and possible mechanisms of ileal transposition on spontaneous non-obese type 2 diabetic GK rats.Methods 20 GK rats were randomly divided into two groups:ileal transposition group and sham operation group (n =10).We observed and determined the weight change,daily average food consumption and FBG (fasting blood-glucose) level of rats before the operation (0 weeks) and 1,4,8,16 and 24 weeks after the surgery.Glucose tolerance test (GTT) was carried out and GLP-1 (glucagon-like peptide-1) concentration measured before the operation (0 weeks) and 4,8,16 and 24 weeks after the surgery and the fasting insulin concentration before the surgery (0 weeks)and 4,24 weeks after the surgery measured,and the indicator of HOMA-IR calculated.Results There was no significant difference in the operating time between the two groups [(87 ± 8) min vs.(84 ± 7)min],P ＞ 0.05.Compared with those before surgery,body weight and food consumption of the two groups of rats decreased significantly a week after surgery (P ＜ 0.05),and then the body weight and food consumption of the two groups of rats all gradually increased,but the difference of the two groups of rats has no statistical significance 1-24 weeks after surgery (P ＞ 0.05).The FBG of the two groups of rats a week after surgery [ileal transposition group (6.1 ± 0.6) mmol/L,sham operation group (6.2 ± 0.8) mmol/L]decreased significantly compared with that before surgery [(7.0 ± 0.5) mmol/L and (6.9 ± 0.5) mmol/L](P ＜ 0.05),and then FBG of the two groups of rats all rose again.The FBG of the rats in surgery group decreased slowly from 8 to 24 weeks after surgery,while the FBG of the rats in the sham surgery group maintained the preoperative level,and the differences of the FBG of the two groups all have statistical significance 8-24 weeks after surgery (P ＜ 0.05).Four weeks after surgery,OGTT of the ileal transposition group significantly improved (P ＜ 0.01).24 weeks after surgery,fasting insulin levels of the ileal transposition group were lower [(0.26 ± 0.08) ng/mL vs.(0.42 ± 0.09) ng/ml],P ＜ 0.05.Compared with the sham surgery group,and HOMA-IR was lower (1.1 ± 0.4) vs.(2.6 ± 0.4),P ＜ 0.05.Four weeks after surgery,oral glucose-stimulated peak (30 min) levels of blood GLP-1 increased markedly in operation groups after surgery (P ＜ 0.01).Conclusions Ileal transposition is effective for the treatment of non-obese T2DM rats,and the control of blood glucose does not depend on the reduction of body weight and food comsumption,and the high secretion of GLP-1 after ileal interposition seem to be helpful in diabetes control.
