目的:探讨腹腔脂肪分布的CT测量与胃癌病人术中淋巴结清扫的关系。方法:回顾性收集2008年5月至2009年9月在我院外科胃切除加D2淋巴结清扫术的226例胃癌病人。手术前通过CT扫描及重建分别测量了腹腔脂肪面积(IFA)及腹腔脂肪体积(IFV)。将IFA分为高IFA组(IFA≥85 cm2)和低IFA组(IFA<85 cm2)两组;IFV分为高IFV组(IFV≥3 000 mL)和低IFV组(IFV<3 000 mL)两组。分别记录病人手术时间、术后胃周淋巴结剥出数,并进行组间比较。结果:大IFA、小IFA两组病人在中位淋巴结检出数分别方面存在明显的统计学差异(P<0.001)。结论:病人腹腔脂肪面积影响胃癌的术中淋巴结清扫个数。
Objective: To investigate the relationship between CT measurement of peritoneal fat distribution and lymph node dissection in patients with gastric cancer. Methods: A retrospective collection of 226 gastric cancer patients who underwent surgical gastrectomy and D2 lymph node dissection in our hospital from May 2008 to September 2009 was retrospectively collected. The peritoneal fat area (IFA) and peritoneal fat volume (IFV) were measured before surgery by CT scan and reconstruction respectively. IFA was divided into high IFA group (IFA≥85 cm2) and low IFA group (IFA <85 cm2). IFV was divided into high IFV group (IFV≥3 000 mL) and low IFV group (IFV <3000 mL) Two groups. The patient’s operation time, the number of gastric lymph node dissection after operation were recorded and compared between groups. Results: There was a significant statistical difference (P <0.001) between the median IFA and the small IFA in the number of median lymph nodes. Conclusion: The number of peritoneal fat area affects the number of lymph node dissection in patients with gastric cancer.
