目的探讨ⅠB期非小细胞肺癌(NSCLC)不同亚组的预后因素。
方法回顾性分析2008年3月至2013年12月间在福建医科大学附属协和医院胸外科接受手术切除的138例ⅠB期NSCLC患者的临床和随访资料。基于国际抗癌联盟(UICC)第七版肺癌分期,再根据肿瘤大小和脏层胸膜受侵情况,将患者细分为3组。ⅠB-a组:肿瘤直径≤3cm且脏层胸膜受侵;ⅠB-b组:3cm<肿瘤直径≤5cm且无脏层胸膜受侵;ⅠB-c组:3cm<肿瘤最大径≤5cm且脏层胸膜受侵。运用Kaplan-Meier生存分析和Cox比例风险模型,对影响NSCLC预后的因素进行分析。
结果ⅠB期NSCLC患者3年总体生存率为88.1%,其中ⅠB-a组75例,ⅠB-b组32例,ⅠB-c组31例,3年生存率分别为92.0%、90.6%和74.1%,3组生存率比较差异有统计学意义(χ2=6.784,P=0.034)。单因素分析显示,无论患者的性别(χ2=0.103,P=0.567)、年龄(χ2=2.463,P=0.117)、手术切除方式(χ2=0.809,P=0.368)、是否接受术后辅助化疗(χ2=0.077,P=0.791),还是肿瘤的位置(χ2=0.091,P=0.674)、脏层胸膜是否受侵犯(χ2=0.085,P=0.771)均无统计学意义,而肿瘤大小(χ2=13.937,P=0.007)和分化程度(χ2=21.198,P=0.000)均有统计学意义。进一步多因素分析显示,只有肿瘤低分化(RR=0.027,95%CI为0.065~0.666,P=0.003)和中分化(RR=1.627,95%CI为1.020~2.597,P=0.008)有统计学意义。
结论ⅠB期NSCLC不同亚组的3年生存率存在统计学差异,TNM分期对ⅠB期的定义可能仍有待改进。肿瘤大小及分化程度是影响患者3年生存率的重要因素,肿瘤中低分化是影响患者3年生存率的独立因素,而术后辅助化疗无影响,该结论有待进一步证实。 相似文献

The laparoscopic approach to appendectomy for acute appendicitis is becoming increasingly favored among surgeons. Endoscopic stapling remains a common approach for division of the appendix and mesoappendix, but staple line bleeding along the mesentery is commonly observed, occasionally demanding surgical control for complete hemostasis. Bioabsorbable seamguard was used as an adjunct to endoscopic stapling of the mesoappendix in 33 consecutive adult patients during laparoscopic appendectomy for acute appendicitis, with complete immediate staple line hemostasis observed by the operative surgeon in all cases. There were no intraoperative complications and no late infectious intra-abdominal complications. There were no postoperative bleeding complications. Bioabsorbable seamguard is a safe and effective adjunct to endoscopic mesoappendiceal stapling which prevents intraoperative and postoperative staple line bleeding. 相似文献

BACKGROUND: There is little information available regarding the relative advantage of stapling over ligation for major pulmonary vessels in lung resection. The thin and fragile structure of pulmonary vascular walls for their large luminal size might have made surgeons reluctant to use staplers. This study was intended to demonstrate the feasibility of pulmonary vascular division by staplers. METHODS: A total of 842 mechanical vascular divisions were performed for pulmonary artery (PA, n=376), pulmonary vein (PV, n=462), and azygos vein (AV, n=4) in 603 consecutive pulmonary resections from 1997 to 1999 at the National Cancer Center Hospital, Tokyo. In this series, 99.8% of mechanical vascular divisions were performed with endostaplers (840 vessels), and only 0.2% was performed with conventional TA-type staplers (two vessels). The prevalence of problems related to mechanical stapling (stapling failure) and postoperative bleeding was studied retrospectively. RESULTS: There was only one incidence of stapling failure, in which the superior pulmonary vein was divided without the formation of staples (overall stapling failure rate, 0.1%). The bleeding was controlled by ligation of each divided stump during thoracotomy. There was no stapling failure for PAs or AVs. In no case did postoperative bleeding require rethoracotomy at the stapled line of the vessels. CONCLUSIONS: Although temporary oozing was sometimes seen along the staple line, vascular division with endostaplers was highly reliable with only a 0.1% incidence of stapling failure for all kinds of vascular structures in the thorax. 相似文献

Background Although a wait of several seconds after clamping is recommended when an automatic stapler is used to achieve adequate hemostasis,
this wait has not been experimentally clarified.
Methods To determine whether waiting is necessary between clamping and firing of a linear stapler, this study evaluated the number
of staple line bleeding points and histologic changes in stapling sites of porcine small intestine (n = 46). It also assessed the ratio of dry to wet tissue weight (DW ratio) (n = 20) of porcine small intestine clamped between the prongs of a linear stapler. The sites were studied separately as follows:
no wait with a four-row device (n = 12), no wait with a six-row device (n = 11), wait with a four-row device (n = 12), and wait with a six-row device (n = 11). The linear stapler was fired immediately after clamping in the no wait group and 1 min after clamping in the wait
group.
Results The mean number of staple line bleeding points in 2 to 5 min with the six-row device and in 3 to 5 min with the four-row device
after firing were significantly less in the wait group than in the no wait group using the same device (p < 0.05). Cross sections of staple lines showed a higher frequency of mucosal cutting in the no wait group than in the wait
group for both the four-row and the six-row devices (both significant at p < 0.01). Although the mean wet tissue weights of anastomotic sites did not change in either group, the mean DW ratio was
significantly less in the wait group than in the no wait group (p < 0.01).
Conclusions A 1-min interval after clamping decreases the amount of clamped tissue. Waiting may thus be necessary to reduce bleeding from
stapling sites, which may be related to a decrease in mucosal cutting. 相似文献

Objective To investigate the association between the home blood pressure (BP) and morality in peritoneal dialysis (PD). Methods PD patients from the First Affiliated Hospital of Zhejiang University from January 1, 2008 to June 30, 2016 were studied. Over the first 6 months PD therapy, systolic SB (SBP) and diastolic BP (DBP) averaged as 5 (<120 to≥150 mmHg in 10 mmHg increments) and 4 (<70 to≥90 mmHg in 10 mmHg increments) categories, respectively, as well as continuous measures. All-cause and cardiovascular mortality were assessed by using Cox regression models adjusted for demographics, laboratory measurements, comorbid conditions and antihypertensive medications. The relationships between home BP and all-cause and cardiovascular mortality were assessed by restricted cubic spline regression model. Results A total of 1663 PD patients were included with a median follow-up of 29.9 months, in which 737 patients (44.3%) were female. The SBP and DBP were (135.2±15.8) mmHg and (83.1±10.5) mmHg, respectively. Two hundred and twenty-one PD patients died during the study period, of which 102 patients (46.2%) died of cardiac-cerebral vascular events. With 130≤SBP<140 mmHg as a refernece, SBP≥150 mmHg (HR=1.83, 95%CI 1.19-2.82, P=0.005) and SBP<120 mmHg (HR=2.05, 95%CI 1.29-3.27, P<0.001) were associated with significantly higher risks of all-cause morality, but not cardiovascular morality. With 80≤DBP<90 mmHg as a refernece, patients with DBP≥90 mmHg exhibited significantly higher risks of all-cause mortality (HR=1.80, 95%CI 1.21-2.68, P=0.009). SBP presented a U-shaped association with all-cause mortality. DBP presented a J-shaped association with all-cause mortality. Conclusions Higher SBP, lower SBP and higher DBP are associated with higher risks of all-cause mortality in PD patients. However, neither SBP nor DBP is observed statistically significant relationship with the risk of cardiovascular mortality. Further prospective and randomized clinical trials are needed to determine the optimal BP targets and improve the management of hypertension in PD patients. 相似文献

BackgroundIn laparoscopic sleeve gastrectomy, tissue thickness and closed staple height of the staple cartridge determine the pressure applied to the tissue. Prior studies have suggested 8 g/mm2 to be ideal to minimize leaks or bleeding.MethodsWe evaluated the relationship between staple loading pressure applied to gastric tissue and bleeding rate prospectively with a novel tissue measuring device and video-recorded operative findings for 116 patients undergoing laparoscopic sleeve gastrectomy performed by 2 surgeons at a single institution. Stapling protocol 1 was used for 64 cases, defined as standard practice, typically using green-blue-blue-blue Ethicon staple cartridges. Stapling protocol 2 was defined as blue-blue-white-white or gold-blue-white-white.ResultsTissue thickness measurements from 39 cases and staple load selection showed that surgeons preferred a median staple loading pressure of 15 g/mm2. Tissue thickness measurements at 15 g/mm2 had a mean of 1.86 mm at the antrum, 1.71 mm at the body, and 1.15 mm at the fundus, all significantly thinner than tissue thickness at 8 g/mm2. For each 10 g/mm2 increase in minimum pressure and maximum pressure value within each cartridge zone, there was a reduction in bleeding rate by 59.8% and 38.7%, respectively. Compared with stapling protocol 1, stapling protocol 2 had a lower intraoperative bleeding rate (90.2% vs 70.7%; P < .0001), usage of preventive hemostatic techniques (100% vs 10%; P < .0001), and hemostatic treatments (66% vs 46%; P = .04). In the 30-day postoperative period, there was 1 bleed in stapling protocol 1; there were no leaks.ConclusionOur data suggest using shorter closed staple heights to exert higher staple loading pressures decreases intraoperative bleeding rates in laparoscopic sleeve gastrectomy. 相似文献

BackgroundLaparoscopic sleeve gastrectomy (LSG) is an approved primary procedure for morbid obesity, but it is associated with serious complications, such as staple line leaks and bleeding. The objective of this study was to assess the effectiveness of staple line reinforcement (SLR) in reducing leaks and bleeding after LSG.MethodsA total of 1162 patients underwent LSG (305 males, 857 females). The mean age was 43.7 years and the mean body mass index was 48 kg/m2. The patients were divided into 6 groups based on the type of SLR, including a no-SLR control group, with evaluation of leaking and bleeding risk and correlation of patients’ characteristics with complications.ResultsA total of 189 patients underwent LSG without reinforcement. The SLR method was oversewing in 476 patients, bovine pericardium in 312, synthetic polyester in 76, glycolide/trimethylene copolymer in 63, and thrombin matrix in 46. The overall leak frequency was 2.8%; higher with synthetic polyester (7.8%), 4.8% with no reinforcement, and lower with bovine pericardium strips (.3%; P<.01). Postoperative hemorrhage occurred in 35 patients (3%), with a higher frequency being observed without SLR (13.7%; P = .02). Only diabetes was a risk-factor for a leak (P< .01).ConclusionSLR with bovine pericardium strips significantly reduced the leak risk. Postoperative bleeding was significantly lower with all SLR-methods, although there was no significant difference among the various techniques. Patients with type II diabetes had a higher risk of staple line leak after LSG. Further randomized, controlled studies are needed to improve our understanding of the efficacy of SLR during LSG. 相似文献

Background
This study aims to identify whether reinforcing the staple line during laparoscopic sleeve gastrectomy (LSG) has advantages.Methods
We searched MEDLINE (PubMed; till August 2011), EMBASE (till August 2011), and the Cochrane Central Register of Controlled Trials (Central) in the Cochrane Library (till August 2011) using common keywords related to sleeve gastrectomy and reinforcement. The keywords were as follows: ??sleeve gastrectomy?? and ??reinforcement,?? or ??reinforcing,?? or ??reinforce,?? or ??leak,?? or ??leakage,?? or ??staple,?? or ??stapling,?? or ??oversew,?? or ??oversewing,?? or ??oversewed.?? The language of publication was limited to English only.Results
Of the 358 articles meeting our initial criteria, eight full texts (two randomized control trial [RCT] and six cohort studies), involving 1,345 participants (828 patient cases and 517 controls) were included in the final analysis. Comparing the reinforcement of the staple line to no reinforcement of the staple line, the odds ratio (OR) for overall complications was 0.521 (95?% confidence intervals [CI], 0.349?C0.777). In addition, the OR for staple line leak was 0.425 (95?% CI, 0.226?C0.799) and for staple line hemorrhage was 0.559 (95?% CI, 0.247?C1.266).Conclusion
The current study showed that reinforcing the staple line during LSG has the following advantages: decreased incidence of postoperative leak and overall complications. More prospective studies with better evidence are needed. 相似文献19.

Background The aim of the study was to compare the results in 95 patients randomly allocated to undergo either stapled or open hemorrhoidectomy using Ligasure.Methods Ninety-five patients with grade III and IV hemorrhoids were randomly allocated to undergo either stapled (50 patients) or open using Ligasure (45 patients). Stapled hemorrhoidectomy was performed with the use of a circular stapling device. Open hemorrhoidectomy was accomplished according to the Milligan-Morgan technique by using Ligasure. Postoperative pain was assessed by means of a visual analog scale (VAS). Recovery evaluation included return to pain-free defecation and normal activities. A 6-month clinical follow-up and an 18 (12-24) month median telephone follow-up were obtained in all patients.Results Operation time for open hemorrhoidectomy using Ligasure was shorter [median 13 (range 9.2-16.1) min vs 15 (range 8-17) minutes, p < 0.05]. Median range of VAS score in the stapled group were significantly lower [VAS score after 8 h: 3 (2-6) vs 5 (3-8), p < 0.01; VAS score after first defecation: 5 (3-8) vs 7 (3-9), p < 0.001. The stapled hemorrhoidectomy was associated with an increased incidence of intraoperative bleeding in 18 cases (36%) vs four cases (8.8%) of the Ligasure group. There were three cases (6%) from the stapled group with recurrence of the hemorrhoids and none from the open technique.Conclusions Hemorrhoidectomy with a circular stapler device is easy to perform, but one more line of clips must be added to the device to avoid intraoperative bleeding from the cut line. Hemorrhoidectomy performed using Ligasure is more painful postoperatively but is a more radical operation. 相似文献

Intraoperative hemostasis and wound healing of 24 side-to-side intestinal anastomoses constructed with the ILA stapling device were studied in 12 dogs by comparing the ILA-32 and ILA-52 staple cartridges. Hemostasis was evaluated by intraoperative measurement of blood loss and bleeding time at the staple line. There was no statistically significant difference in mean blood loss (p greater than 0.05) or mean bleeding time (p greater than 0.10) between the two cartridges. Wound healing was studied using bursting strength measurements and silicone rubber casting of the microvasculature at the staple line. At 3 days, 1 week, and 2 weeks postoperatively, there was no significant difference between bursting strength values achieved with the two cartridges. Microscopic examination revealed that wound healing in the ILA-52 anastomoses lagged behind healing in the ILA-32 anastomoses at each postoperative time period studied. The silicone rubber casting study showed a paucity of microvasculature at the healing staple line with the ILA-52 cartridge as compared with the ILA-32 cartridge. Our findings suggest that the ILA-52 cartridge does not offer significantly improved intraoperative hemostasis over the ILA-32 cartridge and may affect the microvasculature at the staple line in a way that delays wound healing. 相似文献
