目的探讨Billroth-Ⅱ胃大部切除术后输入袢梗阻的诊断和手术方式。 方法本组共17例输入袢梗阻患者，对17例患者的手术史、临床表现及影像学资料进行总结分析。 结果典型的输入袢梗阻表现为上腹胀痛、上腹部触及张力较高且有压痛的囊性包块，腹部CT检查见腹主动脉与肠系膜上动脉之间横向走行的扩张肠管。17例患者均再次行剖腹探查术，术中见输入袢扩张，5例行Braun吻合术，12例行Roux-en-Y吻合术。术后无严重合并症，无围手术期死亡，患者均恢复顺利，梗阻症状消失。术后随访1～4年（平均2.5年），经X线胃肠钡餐检查见吻合口钡剂通过顺利，无狭窄；胃镜检查未见胆汁反流。 结论严格遵守正确的手术操作常规是预防输入袢梗阻的关键；经腹部CT诊断明确后，应尽早再手术；Braun吻合术及Roux-en-Y吻合术为胃大部切除术后输入袢梗阻较理想的术式。
Objective To evaluate the effect of total gastrectomy (TG) and proximal gastrectomy (PG) for the treatment of advanced esophagogastric junction cancer. Methods Clinical data of 273 cases of advanced esophagogastric junction cancer who underwent TG and PG in our hospital from Jan. 2004 to Dec. 2010 were reviewed for retrospective analysis. Operation related indexes, 3-year cumulative survival rate, and 5-year cumulative survival rate were compared and evaluated. Results There was no significant difference between TG group and PG group in intraoperative blood loss, operation time, and hospital stay(P > 0.05), but the number of dissected lymph nodes in TG group was obviously more than those of PG group, and the difference was statistically significant(P=0.000). The postoperative complication rates were 10.3%(12/117)in TG group and 21.8%(34/156) in PG group respectively, which was lower in TG group(χ2=6.353, P < 0.05). The 3-year and 5-year cumulative survival rates of TG group were 58.9% and 34.2%, of PG group were 43.4% and 23.6% respectively, and the 3-year and 5-year cumulative survival rates were all lower in PG group(χ2=5.894, P < 0.05;χ2=5.582, P < 0.05). For patients in stage pT4, pN2, and TNMⅢ, whose tumor size were bigger than 3.0 cm, and patients who had accept chemotherapy, the 3-and 5-year cumulative survival rates of TG group were significantly higher than those of PG group(P < 0.05). However, for patients in stage pT2, pT3, pN0, pN1, pN3, TNMⅠ, TNMⅡ, TNMⅣ, whose tumor size were smaller than 3.0 cm, who had not accept chemotherapy, and patients of any pathological type, there was no statistically significant difference between the 2 groups in 3-year and 5-year cumulative survival rates(P > 0.05). Conclusion For the patients who suffered from advanced esophagogastric junction cancer, TG can improve long-term survival rate, and it can significantly reduce the incidence of postoperative complications and improve postoperative quality of life.
目的评价Roux-en-Y胃空肠吻合术在远端胃大部切除消化道重建中的临床价值。 方法对笔者所在医院科室2009年1月至2012年7月期间31例远端胃癌行Roux-en-Y消化道重建患者的临床资料进行回顾性分析。 结果全组病例无围手术期死亡，无吻合口漏、十二指肠残端瘘、输入空肠段梗阻及倾倒综合征发生。28例（90.3%）患者术后半年进食3～4次/d，每餐量150～400 g；血红蛋白110～150 g/L，血清白蛋白38～50 g/L；24例（77.4%）患者体质量恢复或超过术前水平。胃镜检查未发现反流性食管炎，有残胃炎表现者3例，但无临床症状。 结论Roux-en-Y胃空肠吻合术可成为远端胃大部切除消化道重建的主要术式。
ObjectiveTo compare clinical outcome between single-incision laparoscopic subtotal gastrectomy (SILSG) versus laparoscopy-assisted subtotal gastrectomy (LASG) in treatment of benign gastric ulcer and duodenal ulcer. MethodsClinical data of 37 patients with benign gastric ulcer or duodenal ulcer who underwent laparoscopic subtotal gastrectomy between Jan. 2008 and Feb. 2015 at Shengjing Hospital of China Medical University was collected retrospectively. Among them, 15 patients underwent SILSG and 22 patients underwent LASG. Demographic, intraoperative, and postoperative data was analyzed and compared between the 2 groups. ResultsThe operative time of SILSG group was significantly longer than that of LASG group (P < 0.050). However, the postoperative hospital stay was significantly shorter (P < 0.050), and the total patient scar assesment scale (PSAS) score was significantly lower (P < 0.050) in the SILSG group than those of LASG group. There was no significant difference between the 2 groups with respect to other variables (P > 0.050), such as conversion rate, intraoperative blood loss, postoperative exhaust time, incidence of complication, and visual analog scale score of pain. All patients received postoperative follow up, and the period ranged from 6 months to 25 months, with a median of 11 months. During the follow up period, no one suffered from incision hernia and recurrence of ulcer. ConclusionCompared with LASG, SILSG is a technically feasible procedure with better cosmesis and equivalent curability.
ObjectiveTo explore the effect of exogenous ghrelin on early recovery of rats after subtotal gastrectomy. MethodsTwelve rats undergoing subtotal gastrectomy (B-Ⅰtype) were randomly divided into two groups, and saline or ghrelin was intraperitoneally injected in two groups, respectively. The body weight and daily food intake were measured before operation and on 1-7 d after operation. Rats were killed on day 7 after operation and the expressions of ghrelin mRNA in the fundus of stomach and anastomotic stoma was determined by realtime fluorescent quantitative PCR assay. The anastomotic bursting pressure and hydroxyproline content of anastomotic stoma tissues were also detected. ResultsThere was no significant difference (P＞0.05) in pre and postoperative body weight between two groups. Gradual decrease in postoperative body weight among the rats of saline group was observed which was significantly lower than that before operation (Plt;0.01). Body weight reached it’s lowest on day 1 after operation (Plt;0.01), after which it gradually increased but was still lower than that before operation (Plt;0.01). The postoperative body weight of rats in ghrelin group gradually decreased too, and was also significantly lower than preoperative body weight (Plt;0.01), except for the day 1 after operation (P=0.693). It reached the lowest on day 4 after operation (Plt;0.01), then it gradually increased but was still lower than that before operation (Plt;0.05 or Plt;0.01). The cumulative food intake of rats in ghrelin group was （52.50±6.77） g, which was significantly higher than that in saline group 〔(45.67±7.47) g〕, Plt;0.05. On day 7 after operation, relative expression of ghrelin mRNA in the fundus of stomach of rats in ghrelin group was 0.08±0.04, which was significantly lower than that in saline group (0.22±0.07), Plt;0.01. Compared with saline group, ghrelin-treated rats displayed significantly higher bursting pressure 〔（155.83±6.62） mm Hg vs. （172.33±10.44） mm Hg, Plt;0.05〕 higher hydroxyproline content 〔 (0.43±0.05) μg/mg wet tissue vs. （0.50±0.29） μg/mg wet tissue, Plt;0.01〕 at the anastomotic stoma. ConclusionGhrelin may effectively promote the early recovery of rats after subtotal gastrectomy.
