Effect of lateral lymph nodes dissection and autonomic nerve preservation in anterior resection for rectal cancer: 124 cases review / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical effect of lateral lymph nodes dissection and autonomic nerve preservation in anterior resection for rectal cancer.</p><p><b>METHODS</b>One hundred and twenty-four patients with rectal cancer underwent anterior resection with lateral lymph nodes resection and autonomic nerve preservation. The patients were followed-up through post-operational questionnaire about the function of defecation, urination and sex after the operation. And post-operative survival was analyzed retrospectively.</p><p><b>RESULTS</b>Urinary catheters were removed in 112 cases (90.3%) in 3 days post operation, the mean time of indwelling catheter was (58.3 +/- 2.1) h. Nineteen patients experienced fecal incontinence, 12 cases of them recovered through release-training and one recovered spontaneously. Of the 98 questionnaire respondents, 61 cases (62.3%) could erect normally, and 56 cases (57.1%) had normal sexual function. The max-micturition-desire urine volume was (401.2 +/- 23.1) ml and the residual urine volume was (28.2 +/- 2.2) ml. Five year survival rate of all the patients was 61.2%.</p><p><b>CONCLUSIONS</b>Lateral lymph nodes dissection and autonomic nerve preservation in anterior resection for rectal cancer can decrease the post-operative dysfunction of defecation, urination and sex life and does not affect the survival.</p>

Extended radical resection with nerve-preservation for rectal cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical value of extended radical resection with nerve- preservation for rectal cancer.</p><p><b>METHOD</b>Ninety-eight patients with rectal cancer received extended radical resection with nerve- preservation in our hospital. The questionnaire were used to collect the data of the patients urination and sexual function. The survival was analyzed retrospectively.</p><p><b>RESULTS</b>62.3% (61/98) of the patients could erect normally and 57.1% (56/98) of the patients had normal sexual function. The average time of catheterization in 57 patients was 60 hours, the residual urine volume (RUV) was 28 ml and the max-micturition-desire urine volume was 400 ml. The 5-year survival rate of those who underwent extended radical resection with nerve-preservation was 61.2%.</p><p><b>CONCLUSION</b>Extended radical resection with nerve-preservation,which could decrease the incidences of post-operative urination and sexual dysfunction, and have not affect the survival, was the most optimal operation for rectal cancer.</p>
