Application of delta-shaped anastomosis in billroth-I reconstruction of totally laparoscopic distal gastric cancer radical operation / 重庆医学

Objective To evaluate the safety and short‐term efficacy of delta‐shaped anastomosis in the Billroth‐I reconstruc‐tion of totally laparoscopic distal gastric cancer radical operation (TLDG) .Methods The clinical data in 35 patients with TLDG Delta anastomosis(TLDG group) and 35 patients with laparoscopic assisted distal gastric cancer radical operation (LADG) extraper‐itoneal anastomosis (LADG group) in the gastroenterology department of our hospital from January to December 2014 were ana‐lyzed retrospectively .The intraoperative bleeding volume ,operative time ,gastroenterological function recovery time ,hospitalization duration ,postoperative pathological examination results and hospitalization total cost were compared between the two groups .Re‐sults Seventy cases successfully completed the operation without the cases of conversion to laparotomy and death .The TLDG group had no anastomotic leakage ,bleeding and stenosis after operation ;while the LADG group had 1 case of gastroparesis ,1 case of anastomotic bleeding and 2 cases of anastomotic leakage .The introperative bleeding volume ,tumor size ,number of lymph nodes dissection and distant and proximal incisal margin distance had no statistically significant differences between the two groups (P>0 .05);the operation time ,digestive tract reconstruction time ,first exhaustion time ,time taking liquid diet and postoperative hospital stay time in the TLDG group were significantly shorter than those in LADG group (P< 0 .05) ,but the hospitalization cost was higher than that in the LADG group ,the differences were statistically significant (P<0 .05) .Conclusion The delta‐shaped anasto‐mosis technique is safe and feasible for using in LADG ,moreover has better short‐term effect .

Research progress of three-dimensional laparoscope system / 南方医科大学学报

The lack of depth perception and spatial orientation in two-dimensional image of traditional laparoscopy require long-term training of the surgeons. Three-dimensional (3D) laparoscopy provides stereoscopic visions as compared to monocular views in a traditional laparoscopic system. In this review, the authors summarize the clinical application of 3D laparoscopy and its current research progress.

A comparative study of three-dimensional versus two-dimensional laparoscopic subtotal thyroidectomy via a breast approach / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the safety, efficacy and feasibility of 3D laparoscopic subtotal thyroidectomy via a breast approach.</p><p><b>METHODS</b>The clinical data of 30 patients undergoing 3D laparoscopic subtotal thyroidectomy via a breast approach were analyzed in comparison with 30 patients receiving traditional laparoscopic subtotal thyroidectomy during the period from September, 2013 to December, 2013. The operation time, blood loss, postoperative drainage, postoperative hospital stay, and total hospitalization expenses were compared between the two groups.</p><p><b>RESULTS</b>The operation time in the 3D group was significantly shorter than that in the 2D group (45∓26.3 vs 62∓24.8 min, t=0.53, P<0.05). The intraoperative blood loss, postoperative drainage, postoperative hospital stay and total hospitalization expenses did not show significant differences between the two groups.</p><p><b>CONCLUSIONS</b>3D laparoscopic subtotal thyroidectomy via a breast approach is safe and effective and shortens the operation time, and can be used as a routine operation for subtotal thyroidectomy.</p>
