目的 探讨胰头癌侵犯肠系膜上动脉时行根治性切除的可行性。方法 采用联合将受侵犯的肠系膜上动脉一并切除的胰十二指肠切除术，肠系膜上动脉断端与腹主动脉端侧吻合方式重建。 结果 患者术后恢复顺利，已随访14个月，仍存活。 结论 肠系膜上动脉侵犯的胰头癌仍可行扩大的胰十二指肠切除术，并可延长患者的生存时间和提高生活质量。
目的 探讨小儿结肠系膜淋巴管瘤的诊断与治疗方法。方法 回顾性分析我院2006年1月至2011年12月期间手术治疗的5例小儿结肠系膜淋巴管瘤的临床资料。结果 3例诊断为腹腔包块性质待查的患儿，术中发现腹腔肿块来源于乙状结肠系膜，其中1例肿块侵犯到降结肠系膜达结肠脾曲而行左半结肠切除＋肠吻合术，另外2例行乙状结肠系膜淋巴管瘤切除＋部分乙状结肠切除＋肠吻合术；1例患儿诊断为急性化脓性阑尾炎合并乙状结肠系膜淋巴管瘤，行阑尾切除＋乙状结肠系膜淋巴管瘤切除＋肠吻合术，1例患儿诊断为乙状结肠系膜淋巴管瘤破裂并弥漫性腹膜炎，行乙状结肠系膜淋巴管瘤切除＋乙状结肠造瘘术，术后6个月后再行二期手术。5例患儿手术后恢复良好，未发生吻合口漏等并发症。术后随访5个月～5年， （2.3±1.1）年，1例失访，余均存活，仍在随访中，所有病例均未复发。结论 日常行阑尾手术中，应常规探查小肠、结肠；未进行肠道准备的结肠一期吻合手术中结肠灌洗可减少吻合口漏等并发症的发生率；腹腔感染严重的患儿结肠一期吻合不可取，结肠造瘘安全；小儿结肠系膜淋巴管瘤术前确诊困难，反复出现腹痛、腹部包块的患儿应想到结肠系膜淋巴管瘤的可能性，行充分的肠道准备后择期手术，手术是肠系膜淋巴管瘤唯一的治疗方法。
ObjectiveTo explore the protective effect of low-molecular-weight heparin calcium (LHC) combined with trimetazidine on intestinal smooth muscle of intestinal acute mesangial vein thrombosis (AMVT) in rats and it's mechanism of effect. MethodsA total of 120 SD male rats were randomly divided into three groups, with 40 rats in each group. LHC group: after the AMVT model established, rats were subcutaneous injection the LHC (30 U/100 g) per 12 h until 72 h after surgery. LHC+trimetazidine group (LHCT group): after the AMVT model established, rats were subcutaneous injection the LHC (30 U/100 g) and tail vein injection the trimetazidine (10 mg/kg) per 12 h until 72 h after surgery. Normal saline group (NS group): after the AMVT model established, rats were subcutaneous injection the NS (0.2 mL/100 g) per 12 h until 72 after surgery. The AMVT model were established by blocking superior mesenteric vein of 8 cm and the edge vein arch. Vena cava blood samples and intestinal segments were collected sequentially at 6 h, 12 h, 24 h, 48 h and 72 h afrer surgery. The levels of malondialdehyde (MDA) and creatine kinase (CK) in the blood, and the level of ATP in the intestinal tissue samples were measured with ELISA. Intestinal tissue were taken from the rats for inestinal tissue section, stained with hematoxylin and eosin, examined under light microscopy and evaluated histopathologically using mesemeche scoring system at different time. ResultsCompared with the LHC group and NS group, the levels of MDA and CK in blood and histopathology score of intestinal tissues in rats were significantly decreased, and the level of ATP significantly increased in LHCT group at different time point (P < 0.05). ConclusionTrimetazidine can improve intestinal smooth muscle energy metabolism in the AMVT disease, comined with LHC early can avoid intestinal smooth muscle wall permeability coagulation necrosis and reduce the intestinal smooth muscle damage.
【摘要】目的 观察介入灌注化疗栓塞后手术切除直肠癌的临床疗效。方法 本组31例患者于术前先行区域性动脉灌注化疗加栓塞术，然后多在3～7 d内限期行直肠癌根治术，其中行Dixon术23例， Miles术7例， Hartmann术1例。结果 本组患者术中出血少，肿瘤剥离容易，一般无须输血； 患者术后的肿瘤复发率、转移率和死亡率均优于我科同期术前未行区域性动脉灌注化疗加栓塞术而直接接受手术治疗者。结论 先行区域性动脉灌注化疗栓塞术后再行直肠癌根治性切除，近期疗效好，不失为直肠癌综合治疗的一种新的有效方法。
Objective To evaluate the efficacy of preoperative concurrent chemoradiotherapy combined with total mesorectal excision （TME） in treatment for locally advanced lower rectal cancer. Methods The clinical data of 31 patients with locally advanced lower rectal cancer received concurrent chemoradiotherapy from January 2009 to December 2011 in this hospital were analyzed retrospectively. Conventional fraction radiotherapy with total dose 50 Gy and chemotherapy with mFOLFOX6 or CapeOX regimen were taken. The efficacy was assessed by recording results of clinical and pathological examination. The function of sphincter was also recorded. Results All 31 patients underwent TME operation. The complication morbidity and mortality was 12.9% （4/31） and 3.2% （1/31），respectively. As a result of the preoperative management，the tumor was reduced by an average of 21.9%， down-regulation of T stage was observed in 48.4% （15/31） patients，the frequency of lymph node metastasis decreased from 83.9% （26/31） to 38.7% （12/31）. Pathological complete response was observed in 5 patients （16.1%） and the total response rate was 74.2% （23/31），grade 3/4 toxicity was occurred in 2 （6.5%） patients. 84.6% （22/26） of patients underwent sphincter preservation surgery reserved good function of sphincter. Conclusions Preoperative concurrent chemoradiotherapy combined with TME in treatment for locally advanced lower rectal cancer is effective and safe，which can lead to pathological complete response，decrease the tumor stage and the rate of lymph node metastasis，and can also increase the efficacy of operation.
ObjectiveTo investigate risk factors of anastomotic fistula after total mesorectum excision (TME) in middle and low rectal cancer. MethodsThe clinical data of 446 patients with middle and low rectal cancer received TME surgery from June 2004 to June 2014 were retrospectively analyzed.Single-factor analysis of risk factors was used by χ2 test,multiple-factor analysis was used by logistic regression analysis. ResultsThere were 36 patients with anastomotic fistula in these 446 patients,which of 22 patients were recovered after conservative treatment,of 14 patients were recovered after colostomy.The results of single-factor analysis showed that the age>60 years,preoperative hemoglobin<110 g/L,preoperative albumin<35 g/L,accompanied with diabetes mellitus,neoadjuvant chemoradiation,distance from anasto-mosis to anus<5 cm,non-strengthen suture by hand were the risk factors of anastomotic fistula after TME in the middle and low rectal cancer (P<0.05).The results of multiple-factor analysis showed that the preoperative hemoglobin<110 g/L,preoperative albumin<35 g/L,accompanied with diabetes mellitus,neoadjuvant chemoradiation,and distance from anastomosis to anus<5 cm were the independent risk factors of anastomotic fistula after TME in the middle and low rectal cancer (P<0.05). ConclusionsRisk of anastomotic fistula after TME in middle and low rectal cancer is higher.Basic complications of patient and local conditions of anastomosis,and intraoperative factors could affect incidence of anastomotic fistula,it should be paid enough attention.In general,most of anastomotic fistula could be cured with conservative treatment,in case of conservative treatment is invalid,colostomy is feasible.
ObjectiveTo investigate current status of anal sphincter preservation in low rectal cancer.MethodThe recent literatures on the progress of anal sphincter preservation in the low rectal cancer were reviewed.ResultsIn the past, the surgical treatment of the low rectal cancer was mainly based on the Miles. With the deepening of the anatomical understanding, the improvement of surgical concepts, and the development of minimally invasive techniques, the treatment concept of the low rectal cancer had gradually entered the era of retaining anal and anal function. At present, many surgical methods including the transanal local excision, intersphincteric resection, transanal total mesorectal excision, etc. could be applied to the anal sphincter preservation of the lower rectal cancer, but the advantages and disadvantages of each surgical procedure and the scope of application were slightly different.ConclusionsAlthough there are many surgical procedures that can be applied to patients with low rectal cancer, none of them can achieve perfection in terms of retaining anal and anal function, reducing complications and recurrence rates, and improving survival. It is believed that with continuous understanding of rectal anatomy by surgeons, emergence of various neoadjuvant chemoradiation and new devices, and more anal sphincter preservation procedures and even artificial anal surgery, treatment of low rectal cancer will also be more good care for anal and maintenance function, so that patients can obtain a higher quality and a long-term survival opportunity.
