Comparison of short-term postoperative outcomes between hand-assisted laparoscopic and conventional sigmoidectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To compare the safety and efficacy perioperatively between hand-assisted laparoscopic surgery (HALS) and conventional open sigmoidectomy.</p><p><b>METHODS</b>Prospectively collected data on 115 patients with sigmoid colon cancer between January 2009 to June 2010 were analyzed. There were 62 patients in the HALS group and 53 in the conventional sigmoidectomy group (CS). Patient characteristics, operative parameters, and perioperative outcomes were compared.</p><p><b>RESULTS</b>HALS patients were similar to CS patients in age(60.2 yrs vs. 63.4 yrs, P=0.163), gender (53.2% vs. 60.4% male, P=0.441), tumor size (4.7 cm vs. 5.3 cm, P=0.114) and tumor stage. The two groups were comparable in operative time [(122.4±32.0) min vs.(126.7±37.4) min, P=0.510], lymph node harvest (15.1±4.6 vs. 16.8±6.4, P=0.163), free margin length [(4.1±1.8) cm vs.(4.3±1.7) cm, P=0.601], and postoperative complications. However, HALS group had less intraoperative bleeding [(62.6±35.4) ml vs. (168.9±137.1) ml, P=0.000], shorter time to flatus [(2.3±0.8) d vs. (3.3±1.1) d, P=0.000], and shorter hospital stay [(8.8±2.7) d vs.(12.6±8.0) d, P=0.001].</p><p><b>CONCLUSIONS</b>HALS results in similar short-term outcomes compared to conventional surgery. HALS is safe and minimally invasive.</p>

Application of hand-assisted laparoscopic surgery (HALS) in colectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate the safety and efficacy of hand-assisted laparoscopic surgery (HALS) in colorectal tumors.</p><p><b>METHODS</b>Clinical data of 70 patients with colorectal tumors were retrospectively analyzed. All the patients had received HALS colectomy in the Beijing Cancer Hospital. Lapdisc was used for the hand port at the umbilicus. Two additional trocars were used.</p><p><b>RESULTS</b>There were 38 males and 32 females. The median age was 61(29-89) years. Diagnoses included sigmoid cancer(n=48), sigmoid adenoma(n=4), descending colon cancer (n=3), ascending colon cancer (n=1), rectal cancer (n=13), total colectomy(n=1). The operative time was (126.0±22.5) minutes. The intraoperative blood loss was (75.0±18.8) ml. The mean number of lymph node dissection was(16.8±4.2). The median postoperative hospital stay was 9.4 days. There were no perioperative deaths. One patient developed anastomotic stricture and two anastomotic leak, all of which were successfully managed with conservative treatment.</p><p><b>CONCLUSION</b>HALS is a safe and effective technique for colectomy.</p>
