Short-term efficacy of da Vinci robotic surgical system on rectal cancer in 101 patients / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of da Vinci robotic surgical system in rectal cancer radical operation, and to summarize its short-term efficacy and clinical experience.</p><p><b>METHODS</b>Data of 101 cases undergoing da Vinci robotic surgical system for rectal cancer radical operation from March 2010 to September 2012 were retrospectively analyzed. Evaluation was focused on operative procedure, complication, recovery and pathology.</p><p><b>RESULTS</b>All the 101 cases underwent operation successfully and safely without conversion to open procedure. Rectal cancer radical operation with da Vinci robotic surgical system included 73 low anterior resections and 28 abdominoperineal resections. The average operative time was (210.3±47.2) min. The average blood lose was (60.5±28.7) ml without transfusion. Lymphadenectomy harvest was 17.3±5.4. Passage of first flatus was (2.7±0.7) d. Distal margin was (5.3±2.3) cm without residual cancer cells. The complication rate was 6.9%, including anastomotic leakage(n=2), perineum incision infection(n=2), pulmonary infection (n=2), urinary retention (n=1). There was no postoperative death. The mean follow-up time was(12.9±8.0) months. No local recurrence was found except 2 cases with distant metastasis.</p><p><b>CONCLUSION</b>Application of da Vinci robotic surgical system in rectal cancer radical operation is safe and patients recover quickly The short-term efficacy is satisfactory.</p>

A modified method of laparoscopic side-to-side esophagojejunal anastomosis after laparoscopic total gastrectomy: a report of 12 cases / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the method of alimentary reconstruction after laparoscopic total gastrectomy.</p><p><b>METHODS</b>The clinical data of 12 patients undergone laparoscopic total gastrectomy and side- to- side esophagojejunal anastomosis from Feb. 2006 to Oct. 2006 were analyzed retrospectively.</p><p><b>RESULTS</b>Laparoscopic side- to- side esophagojejunal anastomosis was successfully performed in 12 patients. The mean operation time was (247.0+/- 13.1) min and the anastomosis time was (43.5+/- 10.4) min. Bleeding volume during operation was (107.5+/- 44.9)ml. The distance between anastomosis and proximal margin of tumor was (3.4+/- 1.2)cm. There was no postoperative death, fistula or anastomotic stenosis occurred after short- term follow- up.</p><p><b>CONCLUSION</b>The modified laparoscopic side- to- side esophagojejunal anastomosis is a safe, less challenging and more economic method of alimentary reconstruction after laparoscopic total gastrectomy.</p>

Laparoscopic-assisted radical gastrectomy: a report of 105 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of laparoscopic-assisted radical gastrectomy for gastric cancer.</p><p><b>METHODS</b>One hundred and five patients with gastric cancer received laparoscopic-assisted radical gastrectomy, radical total gastrectomy were performed in 7 cases, proximal gastrectomy in 27 cases, proximal gastrectomy combined with splenectomy in 3 cases and distal gastrectomy in 68 cases.</p><p><b>RESULTS</b>One hundred and five cases had laparoscopic-assisted radical gastrectomy successfully. The mean operation time was 381 +/- 91 (300 - 435) min for total gastrectomy, 279 +/- 73 (212 - 390) min for proximal gastrectomy, 312 +/- 64 (265 - 405) min for proximal gastrectomy combined with splenectomy, 281 +/- 69 (230 - 360) min for distal gastrectomy, respectively. The mean blood loss was 260 +/- 202 (20 - 900) ml in total gastrectomy, 200 +/- 153 (20 - 400) ml in proximal gastrectomy, 333 +/- 116 (200 - 400) ml in proximal gastrectomy combined with splenectomy, 140 +/- 82 (20 - 450) ml in distal gastrectomy, respectively. The mean number of harvested lymph nodes was 34.2 +/- 20.5 (8 - 83). The mean time for gastrointestinal function recovery was 3.5 +/- 1.4 (2 - 5) days, 3.0 +/- 1.6 (2 - 6) days for patients' taking normal activity, 4.9 +/- 1.7 (3 - 7) days for taking liquid food. The short-term efficiency was obvious.</p><p><b>CONCLUSIONS</b>Laparoscopic-assisted radical gastrectomy is a feasible and safe surgical procedure combined with minimal trauma and fast recovery.</p>

Laparoscopy-assisted radical gastrectomy: a report of 71 cases / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of laparoscopy-assisted radical gastrectomy for gastric cancer.</p><p><b>METHODS</b>Seventy-one patients with gastric cancer received laparoscopy-assisted radical gastrectomy for gastric cancer. Among them radical total gastrectomy was performed in 8 cases, proximal partial gastrectomy in 16 cases, proximal partial gastrectomy combined with splenectomy in 3 cases, and distal partial gastrectomy in 44 cases.</p><p><b>RESULTS</b>Sixty-nine cases had laparoscopic-assisted surgery performed successfully, but 2 cases were converted to open surgery. The mean operation time was (343 +/- 52) min for total gastrectomy, (268 +/- 62) min for proximal gastrectomy, (312 +/- 64) min for proximal gastrectomy combined with splenectomy, and (283 +/- 44) min for distal gastrectomy respectively. The mean volume of blood loss was (267 +/- 220) ml in total gastrectomy, (150 +/- 103) ml in proximal gastrectomy, (333 +/- 116) ml in proximal gastrectomy combined with splenectomy, (139+/- 84) ml in distal gastrectomy respectively. The mean numbers of harvested lymph nodes were (34.3 +/- 11.8). The mean time was (4.1 +/- 1.1) d for gastrointestinal function recovery, (3.5 +/- 1.0) d for patient's taking general activity, (5.0 +/- 1.2) d for taking liquid food. The short-term efficiency was obvious.</p><p><b>CONCLUSION</b>Laparoscopy-assisted radical gastrectomy is a feasible, safe and minimally invasive treatment and can achieve the same outcomes as the open operation.</p>
