ObjectiveTo evaluate the efficacy of XiaochengqiMixture (XM) on promoting healing of colonic stoma. MethodsForty Wistar rats were divided into two groups randomly after colonectomy: experimental group (n=20) and control group (n=20). In early postoperatively stage rats were given gastric administration of XM in the experimental group and pure water in the control group. On day 3, 7, and 14 after establishment of animal models, laparotomy was performed in two groups of rats, respectively. Anastomotic stoma and surrounding tissues were harvested to detect the context of hydroxyproline and collagen fiber proportion by Masson dying. ResultsOn day 3 after establishment of animal models, hyperplastic collagen with small fiber was observed while no fasciculus was found. Hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.05). On day 7 after operation, many fasciculuses were found in two groups of rats, hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.01). On day 14 after operation, fasciculuses became bigger and more regular in arrangement, but there was no significant difference between the two groups (Pgt;0.05). ConclusionXM is capable of promoting healing of colonic stoma and might prevent the occurrence of anastomotic fistula.

Objective To investigate the effect of free anterolateral thigh adipofascial flap in correcting the hemifacial atrophy. Methods From January 1997 to May 2006, 35 patients suffering from hemifacial atrophy were corrected with microvascular anastomotic free anterolateral thigh adipofascial flap and other additional measures according to the symptoms of the deformities. There were 11 males and 24 females, aging 1547 years. The locations were left in 12cases and right in 23 cases. The course of disease was 4 to 28 years. Their hemifacial deformities were fairly severity. Their cheeks were depressed obviously. The X-ray films and threedimensinal CT showed the 28 patients’ skeletons were dysplasia. The size of adipofascial flap ranged from 8 cm×7 cm to 20 cm×11 cm. Donor sites weresutured directly. Results Recipient site wound of all patients healed by first intention. All adipofascial flaps survived. The donor sites healed well and no adiponecrosis occurred. Thirty-five cases were followed up for 6 months to 8 years. The faces of all patients were symmetry, and the satisfactory results were obtained. There were no donor site dysfunction. Conclusion The anterolateral thigh adipofascial flapprovides adequate tissue, easytosurvive, no important artery sacrificed and the donor scar ismore easily hidden. Combining with other auxiliary methods, it can be successfully used to correct the deformity of hemifacial atrophy.
目的 探讨应用国产吻合器行直肠癌前切除双吻合器吻合术的可行性。方法 对38例直肠癌患者行前切除时，应用国产直线及管状吻合器行双吻合器吻合。结果 术后发生吻合口漏2例(5.3%)，1例可能与术后早期腹腔化疗有关，另1例形成直肠阴道瘘。全组无吻合口狭窄。结论 国产吻合器在使用上虽不如进口一次性吻合器方便，但如果操作得当，技术熟练，仍可获类似效果，其费用仅为进口吻合器的1/30。新的改进型中国产品应用更方便，更易使此技术推广。
Since Oct. 1990, the 2nd metatarso-phalangeal joint and big-toe nail composite graft with the neuro-vascular bundle was transplanted to reconstruct the thumb in 4 cases. The transplants were all survived. The follow-up through 5 months, a comparatively good function and appearance were achieved.The applied anatomy, the surgical technique and the matters needing attention were detailed.
目的探讨保留幽门的胰十二指肠切除术(PPPD)的手术适应证、捆绑式胰肠吻合术的特点及胃排空障碍的治疗。方法12例均行PPPD，消化道重建按Child法，胰肠吻合均采用捆绑式胰肠吻合。结果除1例术后第21天并发切口裂开、肺栓塞死亡外，其余11例均顺利出院，平均住院时间24 d，随访1年，1例术后8个月死亡，余均健在。结论PPPD是治疗胰头癌及壶腹周围癌的一种具有广阔应用前景的术式，捆绑式胰肠吻合有望作为胰肠吻合的标准术式。
ObjectiveTo investigate the association between the preoperative nutritional risk and anastomotic leakage following anterior resection for the rectal cancer. MethodsA total of 321 patients with rectal cancer underwent anterior resection in our hospital between January 2008 and December 2013 were retrospectively analyzed. Preoperative nutritional status was evaluated using NRS 2002. Correlation of clinicopathologic characteristics with postoperative anastomotic leakage was evaluated using single factor analysis and Logistic regression model. ResultsAmong the 321 patients, the incidence of postoperative anastomotic leakage was 5.6% (18/321). Single factor analysis showed that the NRS2002 score≥3, clinicalpathologic stage (Ⅲ-Ⅳstage) and distance of tumor from the anal verge were the risk factors of anastomotic leakage after anterior leakage following anterior resection for rectal cancer. Logistic regression analysis revealed that the NRS2002 score (OR=4.125, 95% CI=2.062-7.004), clinicalpathologic stage (OR=3.334, 95% CI=2.062-7.004) and the distance of tumor from the anal verge (OR=2.341, 95% CI=2.559-15.838) were the independent risk factors for anastomotic leakage after anterior leakage following anterior resection for rectal cancer. Conciusions Preoperative NRS2002 score is helpful to predict the risk of anastomotic leakage after anterior resection of rectal cancer. Nutrition education should be strengthened to decrease the morbidity of the anastomotic leakage following anterior resection for the patients who's NRS2002 score≥3.
Follow the advance of surgical treatment in complex congenital heart disease, the application of right ventricular(RV)-bypass procedures in RV-hypoplasia/dysfunction was gradually recognized; the pathological pattern of RV-hypoplasia/dysfunction, the histological change of RV-bypass operation and the option on different operative procedure, emphasis on the indication of bidirectional superior cavopulmonary anastomosis(BCPA),the form and method of procedure,and peri-operative management were reviewed in this paper,the optimal age for BCPA, the optimal timing for conversion to Fontan procedure, on pump or off pump, section of the pulmonary trunk, and its difference from hemi-Fontan and 1 1/2 ventricular operation were discussed.
Standard venographies were pcrformed to evaluate the endothelial damage by the contrast medium. After different time intervals, the local veins were prepared for transmission and scanning electron microscopy (TEM and SEM) investigation. The veins were in a dilated state after the angiographies, which lasted for about two days. The endothelial damage was most severe 1 day after the venography. Besides the lesions of extensive endothelial tissurs, dcsquamations, and the exposure of subendothelial tissues, microthrombi somethimes were found. Healing occurred within 3 days. The results this study has also verifieed that it was more valuable to study venogqaphic effects on veins with TEM and SEM.
