胰十二指肠切除术是目前公认的治疗壶腹周围癌的首选方法[1].该术式操作复杂、切除范围广泛、创伤大、术后并发症及死亡率较高.术后胰漏是胰十二指肠切除术最严重的并发症,所以预防胰漏的发生是降低手术病死率的关键所在,而胰漏的发生与术中胰肠吻合处理有直接关系.为预防胰漏的发生,国内外学者近年对各种胰肠吻合方法进行了不断改进[2,3],明显降低了胰漏发生.笔者2005年5月至2009年12月应用改良胰肠吻合术式行胰十二指肠切除术45例,术中运用显微外科技术对胰肠吻合做了全方位的精细处理,术后无1例胰漏发生,效果良好. 相似文献

Splenomegaly is a common problem. In the absence of systemic illness or malignancy splenic cysts must be considered, especially the epithelial variety. For large cysts total splenectomy has long been recommended. Recognition of the risk of an overwhelming postsplenectomy infection (OPSI), especially in children, has led to spleen conserving surgery. We describe the use of an absorbable Vicryl® net after partial splenectomy with total cystectomy in the management of splenic epitelial cysts. 相似文献

BackgroundGraft inflow modulation (GIM) during adult-to-adult living donor liver transplantation (LDLT) is a common strategy to avoid small-for-size syndrome, and some transplant surgeons attempt small size graft strategy with frequent GIM procedures, which are mostly performed by splenectomy, in LDLT. However, splenectomy can cause serious complications such as portal vein thrombosis and overwhelming postsplenectomy infection.MethodsForty-eight adult-to-adult LDLT recipients were enrolled in this study and retrospectively reviewed. We applied the graft selection criteria, which routinely fulfill graft-to-recipient weight ratio ≥ 0.8%, and consider GIM as a backup strategy for high portal venous pressure (PVP).ResultsIn our current strategy of LDLT, splenectomy was performed mostly due to hepatitis C and splenic arterial aneurysms, but splenectomy for GIM was intended to only one patient (2.1%). The final PVP values ≤ 20 mmHg were achieved in all recipients, and no significant difference was observed in patient survival or postoperative clinical course based on whether splenectomy was performed or not. However, 6 of 18 patients with splenectomy (33.3%) developed postsplenectomy portal vein thrombosis (PVT), while none of the 30 patients without splenectomy developed PVT after LDLT. Splenectomy was identified as a risk factor of PVT in this study (P < 0.001). Our study revealed that a lower final PVP could be risk factor of postsplenectomy PVT.ConclusionsUsing sufficient size grafts was one of the direct solutions to control PVP, and allowed GIM to be reserved as a backup procedure. Splenectomy should be avoided as much as possible during LDLT because splenectomy was found to be a definite risk factor of PVT. In splenectomy cases with a lower final PVP, a close follow-up is required for early detection and treatment of PVT. 相似文献

Splenectomy for immune thrombocytopenic purpura: long-term results and treatment of postsplenectomy relapses 总被引:16,自引:0,他引:16
Information regarding prognostic determinants of outcome after splenectomy for adult immune thrombocytopenic purpura (ITP) and the management of postsplenectomy relapse is limited. Among 140 adult patients with ITP who had therapeutic splenectomy at our institution, 88% achieved either a complete (platelets > 150 x 10(9)/l) or a partial (platelets > or = 50 x 10(9)/l) response that was sustained for at least 1 month. At 3, 6, and 12 months after splenectomy, time-adjusted complete response rates were 77%, 71%, and 74%, respectively. The 5-year relapse-free survival was 75%; all but three relapses occurred within 2 years of splenectomy. In multivariate analysis, younger age and higher peak postsplenectomy platelet counts were significantly associated with a favorable response to splenectomy. None of several preoperative or perioperative variables was predictive of a relapse after an initial response to splenectomy. Corticosteroids, danazol, vincristine, and cyclophosphamide were often effective in the treatment of patients who were either refractory to or had a relapse after splenectomy. One patient responded to rituximab after not responding to corticosteroids, azathioprine, and vincristine. After a median follow-up of 37.5 months (range: 0-183) from splenectomy, there were 25 deaths, including 2 from postoperative complications, 1 from gastrointestinal bleeding related to thrombocytopenia, and 1 from overwhelming sepsis related to the splenectomized state. The current study provides additional data on both the long-term outcome of splenectomy in adults with ITP and the management of postsplenectomy relapse. 相似文献

Overwhelming postsplenectomy infection 总被引:3,自引:0,他引:3
BACKGROUND: Splenectomy performed at any age and for any reason increases the risk for death due to overwhelming infection. AIM: To evaluate definition, etiology, incidence, risk factors and prophylaxis of overwhelming postsplenectomy infection, as well as the methods related to splenic tissue preservation when total splenectomy is necessary. METHOD: Bibliographic review. RESULTS: The etiological agents more frequently found are Streptococcus pneumoniae, Haemophilus influenza and type B, and Neisseria meningitidis. Other bacteria like Escherichia coli, Streptococcus b-hemolytic, Staphylococcus aureus and Pseudomonas sp represent a significant risk as well. In addition, a great variety of agents including other enteric Gram-negative microorganisms and non-bacteria pathogens can also be sporadically identified. The prophylaxis is based on three main aspects: patient's education, immune prophylaxis and chemical prophylaxis. However these are not enough to prevent the higher risk of developing sepsis. When total splenectomy is unavoidable, heterotopic splenic autotransplantation seems to be the only alternative for splenic tissue preservation. According to clinical and experimental studies, the splenic autotransplanted tissue present a similar structure to a normal spleen and preserve the splenic immune function. CONCLUSIONS: The high risk of overwhelming postsplenectomy infection, reduced the indication for total splenectomy, in trauma and several diseases. Prophylactic methods have been developed to minimize the effects of the sepsis. Several researches have been done to determine the immunocompetence of autogenous splenic grafts in response to bacteria invasion. 相似文献

Splenectomy for chronic idiopathic thrombocytopenic purpura in children: a single center study in China 总被引:5,自引:0,他引:5
The management of chronic and refractory idiopathic thrombocytopenic purpura (ITP) in children is controversial. We conducted a retrospective review of our single center experience in China between 1990 and 2003 with splenectomy for chronic ITP in children in order to determine the initial and long-term hematological response, morbidity, mortality, predictors of response to splenectomy and the therapy in children who failed splenectomy. Of 65 children analyzed, the overall immediate clinical response to splenectomy was 89.2%. The median postsplenectomy follow-up time was 52 months (8-124). During follow-up, 9 children (13.8%) relapsed within a median time of 6 months (2-58). The overall morbidity was 1.5% and perioperative mortality was zero. During follow-up, 1 child died of intracranial hemorrhage (ICH) and 1 died of overwhelming postsplenectomy infection (OPSI). The platelet count at day 7 after splenectomy was a predictor of a sustained response to splenectomy but no preoperative parameters were predictors of the response to splenectomy. Of the 15 children who failed splenectomy, excluding the one who died of ICH, only 2 children intermittently required corticosteroids and IVIG. Splenectomy is a potential therapy to provide long-term control of disease in children with chronic ITP and is associated with low morbidity and mortality. The risk of fulminant sepsis remains an omnipresent concern. Antipneumococcal vaccination and antibiotic prophylaxis should be recommended and children should receive timely and adequate antibiotics for bacteria infection to lessen the problem of OPSI. 相似文献

BACKGOUND/AIMS: The aims of this study were to evaluate the incidence of overwhelming postsplenectomy infection (OPSI), the usefulness of vaccination in preventing OPSI, and whether affected patients had received the current best practice preventive measures. METHODOLOGY: The patients, observed from June 1991 to May 2005, were reviewed retrospectively. Gender, age, causes of splenectomy, vaccinations and complications were studied. RESULTS: 225 patients (178 males, 47 females) underwent splenectomy, and of these, 79 patients (35.1%) were considered for the present study. Seven patients (8.8%) were informed about the risks of infection and received pneumococcal polysaccharide vaccine after splenectomy. Sixty-eight patients (86.7%) receive influenza vaccine every year. One of the patients that did not receive immunoprophylaxis had OPSI (incidence 1.26%) 1 year after splenectomy. CONCLUSION: Vaccination seems to prevent OPSI. Because of low incidence of OPSI, however, prospective randomised studies in patients without risk factors are needed to evaluate the usefulness of immunoprophylaxis. 相似文献

Patient awareness of health precautions after splenectomy 总被引:2,自引:0,他引:2

Sepsis after splenectomy is a lifelong risk, and patients who have had splenectomy should be educated about this risk. This study examines patient knowledge after splenectomy. We reviewed hospital records of 118 patients who had splenectomies performed between 1982 and 1988 at New Hanover Memorial Hospital. Twenty-four patients have died since their surgery; one death was suspected to be due to postsplenectomy sepsis. Of the 89 patients alive and eligible for follow-up, we were able to query 63. Only 16% were aware of any health precautions. After prompting, patient awareness improved to 40%. We also surveyed 11 of the 14 surgeons who performed the splenectomies. They indicated that they always discuss with their patients the immunologic consequences of spleen removal and the increased risks of infection, although they do not always recommend pneumococcal vaccine. We conclude that splenectomy patients have a low level of knowledge about postsplenectomy infection risks and precautions. We developed an educational pamphlet to aid the surgeon in patient education. 相似文献

Overwhelming postsplenectomy infection. 总被引:4,自引:0,他引:4
W Krivit 《American journal of hematology》1977,2(2):193-201
One of the more intriguing aspects of the spleen is the protection against certain bacterial infections afforded by its unique vascular and immune function. There have been extensive clinical surveys which indicate an incidence of overwhelming postsplenectomy infection (OPSI) above that of the disease for which the splenectomy was done. In the absence of the spleen, either congenital or subsequent to surgical removal, this overwhelming sepsis has a 50% case fatality rate. The most common infective organism has been Diplococcus (tstreptococcus) pneumoniae (D. pneumoniae). Intensive investigations indicated loss of phagocytic function of the spleen, depression of serum IgM levels, a possible suppression of the lymphocyte responsiveness, and changes in opsonin-alternative complement system as potential causes of OPSI. Preventive measures against OPSI include trials of prophylactic Phenoxymethyl Penicillin (penicillin) and pneumococcal vaccine. 相似文献

Splenectomy is considered therapeutic in various non-malignant haematologic diseases. Adverse events ‒ specifically infections and thromboembolism ‒ are not extensively documented in the paediatric population, maintaining the concern over risks-versus-benefits of the procedure. We studied a cohort of paediatric haematology patients undergoing splenectomy between 1977 and 2015 to determine short- and long-term complications. We summarised all the patients of the haematology clinic in our major Israeli tertiary centre undergoing splenectomy for therapeutic reasons, capturing infectious and thromboembolic events. The data of 103 patients, comprising 1657 follow-up years, were analysed. The cohort included 33 patients with transfusion-dependent thalassaemia, seven with non-transfusion-dependent thalassaemia, four with sickle-thalassaemia, 41 with hereditary spherocytosis, and 18 with immune thrombocytopenia. Standard presplenectomy vaccinations were noted in most. No typical cases of overwhelming postsplenectomy infection (OPSI) were identified, nor were typical OPSI bacteria isolated. Thalassaemics with central lines were most prone to infection and thrombosis. Beyond this subgroup, thrombotic events were anecdotal. This is the largest study to date to comprehensively analyse infectious and thrombotic complications of childhood splenectomy for the treatment of haematologic diseases. The use of splenectomy appears to be a relatively safe therapeutic option in paediatric patients with proper preoperative vaccination and follow-up care; use of central venous lines or catheters increase the risk in thalassaemic patients and should be avoided if possible. 相似文献
