Objective To evaluate the curative effectiveness and safety of prophylactic chemohyperthermic peritoneal perfusion (CHPP) during the radical surgery of advancing gastric cancer. Methods We searched MEDLINE (1980 to December 2002), EMBASE (1989 to December 2002), BIOSIS Previews (1980 to December 2002), Cochrane Controlled Trials Register (Issue 4, 2003) and CBMdisc (1981 to December 2002). Randomized or quasi-randomized controlled trials comparing curative gastrectomy (CG) plus CHPP with CG for advancing gastric cancer were collected. The methodological quality of included studies was assessed, and a meta-analysis was performed by RevMan 4.2 software. Results Seven RCTs involving 744 patients met the selection criteria, all trials were of lower methodological quality. ① Meta-analysis results showed that no significant difference was found comparing CG plus CDDP (cisplatin) with CG for peritoneal recurrence after operation (The pooled OR 0.69，95%CI 0.43 to 1.12). Compared with CG alone, CG plus CDDP plus MMC significantly reduced peritoneal recurrence after operation during ≥5 years follow up (OR 0.05, 95% CI 0.01 to 0.37), but this effect was not seen during lt; 5 years follow up (OR 0.35，95%CI 0.06 to 2.10). ② CG plus CDDP significantly reduced mortality after operation during ＜5 and ≥5 years follow up, compared with CG alone (OR 0.25, 95%CI 0.08 to 0.75; the pooled OR 0.62, 95%CI 0.41 to 0.95), CG plus CDDP plus MMC significantly reduced mortality after operation during ≥5 years follow up, compared with CG alone (the pooled OR 0.45, 95%CI 0.28 to 0.74), but this effect was not seen during lt; 5 years follow up (OR 0.29, 95%CI 0.08 to 1.15). ③ Side effects were reported in only one study and no significant difference was found between the two groups (P=0.96). Conclusions Because of the small number of included studies, the lower methodological quality, and the differences in diagnostic criteria of peritoneal recurrence after operation, the reviewers feel that no firm conclusion could be drawn. Some well designed RCTs of CHPP for advancing gastric cancer should be undertaken to further evaluate its effectiveness.
The conectration of cholecystokinin infasting serum was determined by radioimmunoessay in 30 patients with gastric antrum cancer before and after radical sbutotal gastrectomy.It was 119.6±142.2pmol/L before the operation and 78.5±149.2pmol/L after the operation,which was significantly lower than that before the operation,P=0.022. The result suggests that the reduction of cholecytokinin secretion after gastrectomy was one of the important causes in the bile stasis,the disturbance of gallbladder emptying funcion and the formation of gallstone.
Objective To evaluate the clinical application of hand assisted laparoscopic radical surgery for gastric cancer. Methods From June 2010 to September 2011，a series of 51 patients were undertook hand assisted laparoscopic D2 gastrectomy （hand assisted group），49 patients were undertook laparoscopic assisted D2 gastrectomy （laparoscopic group），the secure indexes of surgery effect in perioperative period were compared betwee two groups. Results The incision length was （6.82±0.33） cm and （5.74±1.11） cm （t=6.57，P=0.00），numbers of harvested lymph nodes were 16.10±5.11 and 14.16±3.60 （t=2.18，P=0.03），intraoperative bleeding was （249.40±123.40） ml and （251.00±90.40） ml （t=-0.74，P=0.94），operation time was （177.7±23.8） min and （188.1±16.9） min （t=-2.53，P=0.01），postoperative hospital stay was （11.12±5.02） d and （10.88±3.13） d （t=0.29，P=0.78） in the hand assisted group and in the laparoscopic group，respectively. One case of gastric atony happened in the hand assisted group，one case of gastric atony and incision infection happened in the laparoscopic group. No mortality case was found in two groups. Conclusions Hand assisted laparoscopic D2 gastrectomy is less difficult，and shorter operation time，and considerable treatment effection as compared with laparoscopic operation.
目的总结19例胃癌根治术后合并淋巴瘘的诊治经验。 方法对我院2001年1月至2010年3月期间204例胃癌根治术后19例发生淋巴瘘患者的临床资料进行回顾性分析。 结果19例中15例经非手术治疗治愈，4例因非手术治疗无效行手术探查，其中2例术后痊愈，另2例分别于术后第3天和第6天再次并发淋巴瘘，最终致全身多器官功能衰竭而死亡。 本组淋巴瘘发生率与患者性别、年龄及术前是否化疗无关（Pgt;0.05），但第7、8a、9和16组淋巴结同时有转移者高于无转移者、行D2+手术者高于行D2手术者、使用超声刀者高于未使用者、Ⅱ及Ⅲ期高于Ⅰ期（Plt;0.01），未使用生物蛋白胶者高于使用者、行早期肠内营养者高于晚期肠内营养者、胃中上部肿瘤高于胃下部肿瘤（Plt;0.05）。 TPN加用生长抑素及生长激素者腹腔引流量为（330±40） ml/d，均明显少于单用TPN 〔(750±140) ml/d〕及TPN加用生长抑素者〔(450±40) ml/d〕，Plt;0.01和Plt;0.05，后两者比较其差异也有统计学意义（Plt;0.05）。 TPN加用生长抑素及生长激素患者淋巴瘘的愈合时间为（13.1±1.5） d，较完全TPN的（25.6±2.1） d及TPN加用生长抑素的（18.3±7.1） d缩短，Plt;0.05，后两者比较的差异也有统计学意义（Plt;0.05）。 结论胃癌根治术中可靠结扎淋巴管、避免过度扩大淋巴结清扫范围以及避免早期的肠内营养对预防术后淋巴瘘极为重要。
ObjectiveTo evaluate the lymphatic tracing effects of nano-carbon particles for radical gastrectomy. MethodsTotally eighty-six cases of gastric cancer patients were randomly divided into experimental group (n=43) and control group (n=43). In the experimental group, nanocarbon was injected into the subserosa around the tumor for lymphatic tracing before operation, while no tracer was given in the control group. Then the number of lymph nodes dissected, operation time, and postoperative complications of patients were compared. ResultsThe number of lymph nodes dissected in patients of experimental group was 30.20±11.63 (17-45), which was significantly more than that of control group 〔22.47±7.60 (15-31)〕, Plt;0.05. The blacken rate of lymph nodes in patients of the experimental group was 74.56% (1 260/1 690). Of 302 metastatic lymph nodes, the blacken rate of metastatic lymph nodes was 61.26% (185/302), which was significantly higher than the nonblacken rate of metastatic lymph nodes (38.74%, 117/302), Plt;0.05. The operation time of patients in experimental group 〔(3.51±0.43) h〕 was not different from that in control group 〔(3.49±0.51) h〕, Pgt;0.05. The postoperative complications of patients in two groups was not different and no local or systemic adverse reaction occurred in patients of experimental group. ConclusionSubserosal injection of nanocarbon particles around the tumor is safe and can provide the guidance to lymph node dissection in radical gastrectomy.
ObjectiveTo explore the evaluation value of preoperative multislice spiral computed tomography angiography (MSCTA) for normative radical gastrectomy. MethodsThe anatomic distributions of celiac trunk and its three branches and their tributaries (common hepatic artery, right hepatic artery, left hepatic artery, splenic artery, and left gastric artery) of 86 patients with gastric cancer were comprehended by preoperative MSCTA, which were verified during the surgery. Simultaneously preoperative TNM staging was evaluated by MSCTA, which compared with postoperative pathological results. ResultsThe accuracy rate of preoperative MSCTA evaluating the distribution of celiac trunk and its three branches and their tributaries was 100%. Abnormal hepatic arteries were found in 22 cases by MSCTA, the mutation rate was 25.58%. Abnormal right hepatic arteries were found in 11 cases (12.79%), abnormal left hepatic arteries in 7 cases (8.14%), both abnormal right and left hepatic arteries in 1 case (1.16%), and abnormal common hepatic arteries in 3 cases (3.49%). Straight splenic arteries were found in 24 cases (27.91%), slightly curved splenic arteries in 44 cases (51.16%), and significantly curved splenic arteries in 18 cases (20.93%). Compared with postoperative pathological results, the accuracy rates of preoperative MSCTA evaluating gastric cancer T, N, and M staging were 75.58%（65/86）, 74.42%(64/86), and 91.86%(79/86), respectively. ConclusionsPreoperative MSCTA is an objective way to assess the distributions of celiac artery trunk and related tributaries of patients with gastric cancer. Also, it is an accurate method to evaluate the preoperative TNM stage of gastric cancer, which can help to make an individual operative plan and avoid the intraoperative injury of the artery.
目的 探讨急诊条件下胆囊结石合并胃恶性肿瘤的诊断与治疗。方法 回顾性分析6例因胆囊结石行胆囊切除、术中意外发现胃恶性肿瘤患者的临床资料及治疗过程。结果 6例患者中5例发现胃癌，1例发现原发性胃恶性淋巴瘤。5例施行胃癌根治术，1例施行全胃切除术，无术后并发症，术后定期化疗，随访6～43个月，至术后随访截止日（2008年12月）均存活。结论 老年胆囊结石患者应注意合并胃恶性肿瘤的可能，胆囊切除术中仔细探查胃及周围器官极为重要，同时施行根治性切除是最佳选择。
