Because of hypersplenism and mechanical problems, partial splenectomy was performed in four children with Gaucher's disease. Subsequently, one of the patients underwent a total splenectomy due to bleeding from the remnant of the spleen. At the follow-up of the other three patients, an isotope scan showed that the remaining spleen was functioning well

The long-term outcomes of laparoscopic splenectomy (LS) versus open splenectomy (OS) in patients with idiopathic thrombocytopenic purpura (ITP) are not known. A retrospective analysis of 73 patients who underwent splenectomy (32 LS and 41 OS) for refractory ITP between April 2003 and June 2012 was conducted. LS was associated with shorter hospital stay (P = 0.01), less blood loss and blood transfusion during surgery, quicker resumption of oral diet (P < 0.0001), and earlier drain removal (P < 0.01). Conversion to OS was required in 4 patients (12.5%). Operation time was significantly longer in LS (P < 0.0001). Deep venous thrombosis (DVT) was observed in 1 patient after LS and in 4 patients after OS (P = 0.52). One patient died from intraperitoneal bleeding after OS, another patient developed pulmonary embolism. Median follow-up of 36 months was performed in LS group (29 of 32, 91%) and of 46 months in OS group (35 of 41, 85%), 25 patients (86%) in LS group and 32 (91%) in OS group reached sustained complete response (P = 0.792). Kaplan-Meier analysis showed that there was no significant difference in the relapse-free survival rate between the groups (P = 0.777). In conclusion, the long-term outcome of laparoscopic splenectomy is not different from that of open splenectomy for patients with ITP. PMID:24833154

Corticosteroids are still the standard first-line treatment for immune thrombocytopenic purpura (ITP). As second-line therapy, splenectomy and Rituximab are both recommended. The aim of our study was to compare the efficacy of Rituximab to splenectomy in persistent or chronic ITP patients. Between January 1999 and March 2015, we retrospectively selected all consecutive patients who underwent an ITP second-line treatment: Rituximab or splenectomy. The distinction between open (OS) and laparoscopic splenectomy (LS) was analyzed. Primary outcome was composite: hospitalization for bleeding and/or thrombocytopenia and death from hemorrhage or infection. Secondary outcomes were based on response (R) and complete response (CR) rates as defined by the American Society of Hematology. Ninety-six patients were included: 30 patients received Rituximab, 37 underwent OS, and 29 underwent LS. The follow-up was 30, 60, and 120 months in Rituximab, LS, and OS groups, respectively. At 30 month, the primary outcome-free survival rate was higher in splenectomy groups (84% for OS, 86% for LS) than Rituximab group (47%) (P = 0.0002). Similarly, at 30 month, R and CR rates were higher for OS (86.5% and 75.7%, respectively) and LS groups (93.1% and 89.7%) than Rituximab (46.7% and 30%) (P = 0.0001). Moreover, R rates remained elevated at 60 month for OS and LS groups (83.7% and 89.6% respectively) and 78.4% at 120 month for OS group. We observed that splenectomy for ITP second-line treatment was more effective than Rituximab regarding maintenance of R, CR, and overall response rates. OS and LS had similar efficacy.

Laparoscopic splenectomy for massive splenomegaly is still a controversial procedure as compared with open splenectomy. We aimed to compare the feasibility of laparoscopic splenectomy versus open splenectomy for massive splenomegaly from different surgical aspects in children. The data of children aged splenectomy for hematologic disorders were retrospectively reviewed in 2 pediatric surgery centers from June 2004 until July 2012. The study included 32 patients, 12 who underwent laparoscopic splenectomy versus 20 who underwent open splenectomy. The mean ages were 8.5 years and 8 years in the laparoscopic splenectomy group and open splenectomy group, respectively. The mean operative time was 180 minutes for laparoscopic splenectomy and 120 minutes for open splenectomy. The conversion rate was 8%. The mean amount of intraoperative blood loss was 60 mL in the laparoscopic splenectomy group versus 110 mL in the open splenectomy group. Postoperative atelectasis developed in 2 cases in the open splenectomy group (10%) and 1 case in the laparoscopic splenectomy group (8%). Oral feeding postoperatively resumed at a mean of 7.5 hours in the laparoscopic splenectomy group versus 30 hours in the open splenectomy group. The mean hospital stay was 36 hours in the laparoscopic splenectomy group versus 96 hours in the open splenectomy group. Postoperative pain was less in the laparoscopic splenectomy group. Laparoscopic splenectomy for massive splenomegaly in children is safe and feasible. Although the operative time was significantly greater in the laparoscopic splenectomy group, laparoscopic splenectomy was associated with statistically significantly less pain, less blood loss, better recovery, and shorter hospital stay. Laparoscopic splenectomy for pediatric hematologic disorders should be the gold-standard approach regardless of the size of the spleen.

Splenectomy is considered standard surgical therapy in hereditary spherocytosis. The procedure is indicated in patients with severe anemia, recurrent hemolytic, and aplastic crises. The aim of the study was to assess treatment outcomes in patients with hereditary spherocytosis who underwent total or partial laparoscopic splenectomy. Fifteen patients aged 4-17 yr underwent laparoscopic splenectomy from 2009 to 2012. Partial and total splenectomies were performed (five and 10 children, respectively). Hematologic parameters, liver function tests, and splenic volume before and after the surgery were analyzed retrospectively. Total follow-up was 1-30 months. Hospitalization and operating time were similar in both groups. In partial splenectomy group, branches of splenic arteries gave better blood supply than short gastric vessels. In both groups, hematologic parameters were improved. Postoperative markedly elevated platelet count was maintained up to 6 months, and after that, platelet count gradually decreased to normal values. Bilirubin level was decreased in early postoperative period; however, it increased later to achieve levels lower than in preoperative period. No severe general infections were observed in both groups. Laboratory parameters (hemoglobin and bilirubin concentrations and RBC) after the surgery improved in all patients, and the effect was maintained during 12 months of follow-up. Platelet count increased significantly after the surgery and was maintained at high levels during the next 6 months. However, it returned to preoperative levels within a year after the surgery. Our study showed that partial splenectomy was not inferior to total splenectomy. However, full assessment requires longer follow-up and larger group of patients. © 2015 John Wiley & Sons A/S.

For proximal gastric cancer invading the greater curvature, concomitant splenectomy is frequently performed to secure the clearance of lymph node metastases. However, prognostic impact of prophylactic splenectomy remains unclear. The aim of this study was to clarify the oncological significance of prophylactic splenectomy for advanced proximal gastric cancer invading the greater curvature. Retrospective review of 108 patients who underwent total or subtotal gastrectomy for advanced proximal gastric cancer involving the greater curvature was performed. Short-term and long-term outcomes were compared between the patients who underwent splenectomy (n = 63) and those who did not (n = 45). Patients who underwent splenectomy showed higher amount of blood loss (538 vs. 450 mL, p = 0.016) and morbidity rate (30.2 vs. 13.3, p = 0.041) compared with those who did not undergo splenectomy. In particular, pancreas-related complications were frequently observed among patients who received splenectomy (17.4 vs. 0%, p = 0.003). However, no significant improvement of long-term outcomes were confirmed in the cases with splenectomy (5-year recurrence-free rate, 60.2 vs. 67.3%; p = 0.609 and 5-year overall survival rates, 63.7 vs. 73.6%; p = 0.769). On the other hand, splenectomy was correlated with marginally better survival in patients with Borrmann type 1 or 2 gastric cancer (p = 0.072). For advanced proximal gastric cancer involving the greater curvature, prophylactic splenectomy may have no significant prognostic impact despite the increased morbidity rate after surgery. Such surgical procedure should be avoided as long as lymph node involvement is not evident.

To evaluate changes in annual blood transfusion requirements and complications after splenectomy in patients with β-thalassemia. Forty post-splenectomy β-thalassemic patients aged 8-33 y, receiving regular blood transfusions and chelation therapy were included and non transfusion dependant patients were excluded from this retrospective cross-sectional study. Details about their surgery, transfusion requirements, and platelet levels were recorded on a standard proforma. All patients underwent a B-mode and color-coded duplex sonography of the hepatoportal system during the study period. The average ferritin level in the year prior to the study was 4432 mcg/L (range 480-12,200 mcg/L). The annual blood transfusion requirement in the first year and 5 y post splenectomy [mean ± SD (138.41 ± 90.38 ml/kg/y); (116 ± 41.44 ml/kg/y)] were significantly different from requirements before splenectomy [(mean ± SD) 294.85 ± 226 ml/kg/y; p value splenectomy with a mean rise of 4,51,000/mm(3) (p value splenectomy. Increase in annual blood transfusion requirement should be investigated to find the cause.

Thirty-four patients with Hodgkin's disease and non-Hodgkin's lymphoma underwent therapeutic splenectomies to improve hematologic tolerance for chemotherapy. The mean age was 40 years; there were 16 males and 18 females. Fourteen had Hodgkin's disease, 19 had non-Hodgkin's lymphoma, and 1 had malignant histocytosis. Nineteen had palpable splenomegaly, 19 had marrow involvement and 20 had splenic involvement by lymphoma. The following data were analyzed before and after splenectomy: mean white blood cell count (WBC) and platelet count on planned first day of cycle, delay ratio of chemotherapy delivery and percent maximal dose rate. Thirteen patients had non-Hodgkin's lymphoma, splenomegaly and positive bone marrow and showed significant benefit in all of the aforementioned parameters. Of the patients with prior irradiation, only those who completed their radiation greater than six months prior to splenectomy showed benefit. Ten patients had Hodgkin's disease, negative bone marrow and no splenomegaly. This group showed significant improvement in mean platelet count but more limited benefit in delay ratio and percent maximal dose rate. Thus, selected patients with lymphoma who are experiencing delays in chemotherapy because of poor count tolerance may benefit from splenectomy

Total splenectomy in sickle cell disease is related to a high risk of fulminant sepsis and increased incidence of other events, which have not been reported in patients with partial splenectomy. In this study we examined the patients with sickle cell disease and partial splenectomy and compared the clinical and laboratory results with non-splenectomized patients. We studied 54 patients with sickle cell disease who underwent partial splenectomy in childhood from 1986 until 2011 at the Institute of Hematology and Immunology. They were compared with 54 non-splenectomized patients selected by random sampling with similar characteristics. Partial splenectomy was performed at a mean age of 4.1 years, with a higher frequency in homozygous hemoglobin S (70.4%), and the most common cause was recurrent splenic sequestration crisis. The most common postoperative complications were fever of unknown origin (14.8%) and acute chest syndrome (11.1%). After splenectomy there was a significant increase in leukocytes, neutrophils, and platelets, the latter two parameters remained significantly elevated when compared with non-splenectomized patients. There was no difference in the incidence of clinical events, except hepatic sequestration, which was more common in splenectomized patients. Partial splenectomy was a safe procedure in patients with sickle cell disease. There were no differences in the clinical picture in children splenectomized and non-splenectomized except the greater frequency of hepatic sequestration crisis in the first group.

Al-Salem, Ahmed H

2016-01-01

Splenomegaly and hypersplenism are common complications among children with thalassemia necessitating splenectomy. Thirty-six children (27 β-thalassemia major, 3 Hb H disease, and 6 thalassemia intermediate) had total splenectomy (11 laparoscopic and 13 open splenectomy) or partial splenectomy (12 patients). In the partial splenectomy group, 2 with Hb H required no transfusions. For those with β-thalassemia major who had partial splenectomy (9 patients), there was a reduction in the number of transfusions from a preoperative mean of 15.2 transfusions per year to a postoperative mean of 8.2 transfusions per year. Subsequently and as a result of increase in the size of splenic remnant, their transfusions increased, but none required total splenectomy. Twenty-four patients had total splenectomy (13 open and 11 laparoscopic splenectomy). Their postsplenectomy transfusions decreased from a preoperative mean of 17.8 transfusions per year to a postoperative mean of 10 transfusions per year. There was no mortality, and none developed postoperative sepsis or thrombotic complications. Total splenectomy is beneficial for children with β-thalassemia major and hypersplenism by reducing their transfusion requirements. Laparoscopic splenectomy is however more beneficial. Partial splenectomy reduces their transfusion requirements, but only as a temporary measure, and so it is recommended for children younger than 5 years of age.

Full Text Available Objectives: Splenectomy is performed in order to provide the treatment in the patients with severe idiopathic thrombocytopenic purpura, refractory to medical treatment. In this study, we aimed to investigate the postoperatif and longterm outcomes in the patients who underwent splenectomy with the diagnosis of idiopathic thrombocytopenic purpura.Materials and Methods: Between 2001-2010 at Dicle University Medical Faculty, General Surgery Department, a retrospective review of the 109 patients who had undergone splenectomy for ITP was reviewed. Age, gender, presence of accessory spleens and location, duration of the operation, number of preoperative platelet tranfusion, number of preoperative and postoperative blood transfusion, length of hospital stay, long-term outcomes, morbidity and mortality were recorded.Results: The mean age was 37.10 ± 16.62 (16-72, and there were 88 (80.7% female and 21 (19.3% male patients. The mean operation time was 44.87 ± 10:32 (30-120 minutes. The average postoperative blood and preoperative platelet transfusion were 1.63 ± 0.85 (0-3 and 2.01 ± 0.71 (1-3 units, respectively. The accessory spleens were encountered in 20 (18.3% patients at the ultrasonographic examination. And also the accessory spleens were encountered in 23 (21.1% patients during operation and confirmed with histopathologic examination. The most common localization of accessory spleens were splenic hilus. The postoperative complications were occurred in 16 patients (14.7% and the most complication was atelectasia. The mean length of hospital stay was 4:56 ± 2:45 (2-12 days. Patients were followed for an average of 28 (9-48 months. At the follow-up period, 1 (0.9 % patient had died.Conclusion: Splenectomy can be performed safely in the treatment of the patients with idiopathic thrombocytopenic purpura unresponsive to medical treatment. Long-term good results can be obtained with splenectomy in these patients. The accessory spleens should not be

Background IL28B and ITPA genetic variants are associated with the outcome of pegylated-interferon and ribavirin (PEG-IFN/RBV) therapy. However, the significance of these genetic variants in cirrhotic patients following splenectomy has not been determined. Methods Thirty-seven patients with HCV-induced cirrhosis who underwent laparoscopic splenectomy (Spx group) and 90 who did not (non-Spx group) were genotyped for IL28B and ITPA. The outcome or adverse effects were compared in each group. Interferon-stimulated gene 15 (ISG15) and protein kinase R expression in the spleen was measured using total RNA extracted from exenterate spleen. Results Sustained virological response (SVR) rate was higher in patients carrying IL28B major genotype following splenectomy (50% vs 27.3%) and in patients carrying minor genotype in the Spx group compared to non-Spx group (27.3% vs 3.6%, P splenectomy did not increase hemoglobin (Hb) level, Hb decline tended to be greater in the non-Spx group. In contrast, splenectomy significantly increased platelet count (61.1 × 103/μl vs 168.7 × 103/μl, P splenectomy. Splenectomy improved SVR rate among patients carrying IL28B minor genotype and protected against anemia and thrombocytopenia during the course of PEG-IFN/RBV therapy regardless of ITPA genotype.

BACKGROUND Portal venous system thrombosis (PVST) is a life-threatening complication of liver cirrhosis. We conducted a retrospective study to comprehensively analyze the prevalence and risk factors of PVST in liver cirrhosis. MATERIAL AND METHODS All cirrhotic patients without malignancy admitted between June 2012 and December 2013 were eligible if they underwent contrast-enhanced CT or MRI scans. Independent predictors of PVST in liver cirrhosis were calculated in multivariate analyses. Subgroup analyses were performed according to the severity of PVST (any PVST, main portal vein [MPV] thrombosis >50%, and clinically significant PVST) and splenectomy. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. RESULTS Overall, 113 cirrhotic patients were enrolled. The prevalence of PVST was 16.8% (19/113). Splenectomy (any PVST: OR=11.494, 95%CI=2.152-61.395; MPV thrombosis >50%: OR=29.987, 95%CI=3.247-276.949; clinically significant PVST: OR=40.415, 95%CI=3.895-419.295) and higher hemoglobin (any PVST: OR=0.974, 95%CI=0.953-0.996; MPV thrombosis >50%: OR=0.936, 95%CI=0.895-0.980; clinically significant PVST: OR=0.935, 95%CI=0.891-0.982) were the independent predictors of PVST. The prevalence of PVST was 13.3% (14/105) after excluding splenectomy. Higher hemoglobin was the only independent predictor of MPV thrombosis >50% (OR=0.952, 95%CI=0.909-0.997). No independent predictors of any PVST or clinically significant PVST were identified in multivariate analyses. Additionally, PVST patients who underwent splenectomy had a significantly higher proportion of clinically significant PVST but lower MELD score than those who did not undergo splenectomy. In all analyses, the in-hospital mortality was not significantly different between cirrhotic patient with and without PVST. CONCLUSIONS Splenectomy may increase by at least 10-fold the risk of PVST in liver cirrhosis independent of severity of liver dysfunction.

Patients undergoing synchronous open splenectomy and hepatectomy (OSH) for concurrent hepatocellular carcinoma (HCC) and hypersplenism usually have major surgical trauma caused by the long abdominal incision. Surgical procedures that contribute to rapid recovery with the least possible impairment are desired by both surgeons and patients. The objective of this study was to explore outcomes in patients treated with simultaneous laparoscopic or open splenectomy and hepatectomy for hepatocellular carcinoma (HCC) with hypersplenism. We retrospectively evaluated the treatment outcomes in 23 patients with cirrhosis, HCC, and hypersplenism, who underwent simultaneous laparoscopic splenectomy and hepatectomy (LSH; n = 12) or open splenectomy and hepatectomy (OSH; n = 11) from January 2012 through December 2015. Their perioperative variables were compared. LSH was successful in all patients. There were nonsignificant similarities between the 2 groups in duration of operation, estimated blood loss, and volume of blood transfused ( P > .05 each). Compared with OSH, LSH had a significantly shorter postoperative visual analog scale pain score ( P 38.0°C ( P < .01); fewer postoperative complications ( P < .05); and better liver and renal function on postoperative days 7 ( P < .05 each). Simultaneous LSH is safe for selected patients with HCC and hypersplenism associated with liver cirrhosis.

The recent large decrease in splenectomy use for chronic immune thrombocytopenia (ITP) is partly due to still-unsolved questions about long-term safety. We performed the first single-center exposed/unexposed cohort study evaluating the long-term incidence of splenectomy complications in patients with primary ITP. Overall, 83 patients who underwent splenectomy more than 10 years ago (exposed) were matched with 83 nonsplenectomized patients (unexposed) on the date of ITP diagnosis ±5 years, age and gender. After a median follow-up of 192 months (range 0.5-528), 43 patients (52%) achieved overall response after splenectomy. Splenectomized patients experienced more venous thromboembolism (VTE) than controls (n = 13 vs n = 2, P = 0.005). On multivariate analysis, splenectomy was an independent risk factor of VTE (hazard ratio = 4.006, P = 0.032 [95% confidence interval: 1.13-14.21]). Splenectomized patients presented more severe infections on long-term follow-up: all required hospitalization, and 5/26 (19%) infections led to severe sepsis or septic shock and to death for 3 cases (none in controls). However, the incidence of malignancy was similar in both groups, as was cardiovascular risk, which appeared to be related more to ITP than splenectomy. Finally, splenectomy did not significantly decrease overall survival. Despite the risk of thrombosis and severe sepsis, splenectomy remains an effective and curative treatment for ITP.

The risks that arise after splenectomy can be divided in infectious and non-infectious. The link between splenectomy and these hazards remains partially unknown. Host defense against infection is altered after splenectomy and such individuals develop sepsis more easily and the infection has a fulminant course. Splenectomy is also a potential risk factor for several vascular complications that result from partial or total obstruction of an arterial or venous blood vessel. Furthermore, pulmonary hypertensioncan be a severe and sometimes fatal complication following splenectomy. Some authors also consider that malignancies, diabetes mellitus and acute pancreatitis are non-infectious complications after splenectomy. The most feared complication for splenectomized patients remains sepsis. The pathophysiology of sepsis is still controversial. Death in sepsis can occur due to either hyper-inflammation or immune paralysis. Multiple experimental evidences link cellular and viral microRNAs with sepsis. We presume that miRNAs are also associated with the immunosuppression of the asplenic patients which leads to the high risk of deadly sepsis. Studying the expression level of circulating miRNAs in asplenic patients could help us better understand the postsplenectomy immunosuppression and develop new diagnostic and therapeutic tools.

Patients with thrombotic thrombocytopenic purpura (TTP), Moschowitz's disease, run a high risk of perioperative bleeding and need intensive hematologic support. In some patients, TTP is associated with cancer but the surgical role in these patients is still unclear. To illustrate the surgical problems and outcome we present the case histories of three patients with TTP observed in our emergency department. Two patients had TTP secondary to cancer and one patient with primary TTP (no evidence of neoplasia) had emergency operation for gastric hemorrhage, occlusion and TTP unresponsive to plasmapheresis. The first two patients who had not radical resection of cancer and no splenectomy, died for TTP complications. The third patient who underwent emergency splenectomy, had an uneventful postoperative course and TTP completely regressed. These case reports suggest that patients with TTP should be screened to rule out cancer. In patients with acute cancer-related complications emergency surgery should aim to resect the cancer. An associated splenectomy may increase the effectiveness of postoperative hematologic therapy.

The treatment of hepatocellular carcinoma (HCC) is complicated and challenging because of the frequent presence of cirrhosis. Therefore, we propose a novel surgical approach to minimize the invasiveness and risk in patients with HCC, hypersplenism, and esophagogastric varices. This was a retrospective study carried out in 25 patients with HCC and hypersplenism and who underwent simultaneous laparoscopic-guided radio-frequency ablation and laparoscopic splenectomy with endoscopic variceal ligation. Tumor size was restricted to a single nodule of splenectomy. Laparoscopic-guided radio-frequency ablation with laparoscopic splenectomy and endoscopic variceal ligation could be an available technique for patients with HCC <3 cm, hypersplenism, and esophagogastric varices. This approach may help to minimize the surgical risks and results in a fast increase in platelet counts with an acceptable rate of complications.

AIM: To investigate whether the use of synchronous hepatectomy and splenectomy (HS) is more effective than hepatectomy alone (HA) for patients with hepatocellular carcinoma (HCC) and hypersplenism. METHODS: From January 2007 to March 2013, 84 consecutive patients with HCC and hypersplenism who underwent synchronous hepatectomy and splenectomy in our center were compared with 84 well-matched patients from a pool of 268 patients who underwent hepatectomy alone. The short-term and long-term outcomes of the two groups were analyzed and compared. RESULTS: The mean time to recurrence was 21.11 ± 12.04 mo in the HS group and 11.23 ± 8.73 mo in the HA group, and these values were significantly different (P = 0.001). The 1-, 3-, 5-, and 7-year disease-free survival rates for the patients in the HS group and the HA group were 86.7%, 70.9%, 52.7%, and 45.9% and 88.1%, 59.4%, 43.3%, and 39.5%, respectively (P = 0.008). Platelet and white blood cell counts in the HS group were significantly increased compared with the HA group one day, one week, one month and one year postoperatively (P Splenectomy and micro-vascular invasion were significant independent prognostic factors for disease-free survival. Gender, tumor number, and recurrence were independent prognostic factors for overall survival. CONCLUSION: Synchronous hepatectomy and hepatectomy potentially improves disease-free survival rates and alleviates hypersplenism without increasing the surgical risks for patients with HCC and hypersplenism.

Laparoscopy offers many benefits to splenectomy, such as reduced incisional pain and shortened hospital duration. The purpose of this study is to evaluate procedural and outcome differences between multiport (MP) and reduced port (RP) splenectomy when utilized to treat children. An institutional review board approved retrospective analysis of all consecutive laparoscopic total splenectomies performed at a single institution between January 2010 and October 2015 was conducted. We evaluated demographics, surgical technique, instance of conversion, operative duration, estimated blood loss, need for intraoperative blood transfusion, postoperative length of stay, time to full feeds, complications, and follow-up duration. Over a 5-year period, 66 patients less than 20 years of age underwent laparoscopic total splenectomy. RP splenectomy was attempted in 14 patients. The remaining 52 were MP operations. Populations were comparable with regard to demographics. Preoperative splenic volumes (mL) were greater in the RP population (median [IQR]: 1377 [747-1508] versus 452 [242-710], P = .039). RP splenectomy demonstrated no difference compared to MP splenectomy in operative time (153 versus 138 minutes, P = .360), estimated blood loss (120 versus 154 mL, P = .634), or percent of cases requiring intraoperative blood transfusion (14 versus 23, P = .716). By the first postoperative day, 57% of RP and 17% of MP patients could be discharged (P = .005). Thirty-day readmission rates were similar, at 7% for RP and 8% for MP operations. Fever was the indication for all readmissions. Mean duration of follow-up is 28 months for MP and 13 months for RP cases. A reduced number of ports can be safely utilized for total splenectomy in pediatric patients without increasing procedural duration or need for intraoperative blood transfusion. In addition, rate of discharge on the first postoperative day was significantly higher in the RP splenectomy group.

Complete cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) is increasingly performed on patients with peritoneal carcinomatosis of various origins. Splenectomy often is required in these patients to achieve complete tumor removal. Although splenectomy has been associated with increased morbidity in many major abdominal surgeries, its effect in patients undergoing CRS + HIPEC is unknown. The purpose of this study was to evaluate the impact of splenectomy during CRS + HIPEC on postoperative outcomes. We retrospectively identified 39 patients who underwent CRS + HIPEC with splenectomy during a 3-year study period from a prospective database. We compared them to case controls (CRS + HIPEC without splenectomy) that were matched for the complexity of the procedure. We evaluated the complication rate and outcomes of patients in each group. During the study period, splenectomy was performed in 32 % of patients undergoing CRS + HIPEC procedure. Patients in the splenectomy group experienced more grade 3-4 complications than patients in the control group (59 vs. 35.9 %, p = 0.041) as well as more pulmonary complications (41 vs. 7.7 %, p = 0.0006). Multivariate analysis identified splenectomy as the only predictor of overall major complications (odds ratio = 2.57, 95 % confidence interval = 1.03-6.40). Mortality was similar in both groups. Splenectomy increases major complication rate in patients undergoing CRS + HIPEC and efforts should be made to preserve the spleen during the surgery.

In patients with immune thrombocytopenia (ITP) refractory to corticosteroids and intravenous immunoglobulins (IVIG), splenectomy may result at higher risk of peri-operative complications and, for this reason, potentially contraindicated. The thrombopoietin receptor agonists (TPO-RAs) romiplostim and eltrombopag have shown high therapeutic activity in primary ITP, but data of efficacy and safety regarding their use in preparation for splenectomy are missing. Thirty-one adult patients, median age 50 years, with corticosteroids and/or IVIG refractory persistent and chronic ITP who were treated with TPO-RAs (romiplostim= 24; eltrombopag= 7) with the aim to increase platelet count and allow a safer execution of splenectomy were retrospectively evaluated. Twenty-four patients (77%) responded to the use of TPO-RAs with a median platelet count that increased from 11 × 10(9) /L before starting TPO-RAs to 114 × 10(9) /L pre-splenectomy, but a concomitant treatment with corticosteroids and/or IVIG was required in 19 patients. Twenty-nine patients underwent splenectomy while two patients who responded to TPO-RAs subsequently refused surgery. Post-splenectomy complications were characterized by two Grade 3 thrombotic events (1 portal vein thrombosis in the patient with previous history of HCV hepatitis and 1 pulmonary embolism), with a platelet count at the time of thrombosis of 260 and 167 × 10(9) /L, respectively and one Grade 3 infectious event. TPO-RAs may represent a therapeutic option to improve platelet count and reduce the risk of peri-operative complications in ITP candidates to splenectomy. An increased risk of post-splenectomy thromboembolic events cannot be ruled out and thromboprophylaxis with low-molecular weight heparin is generally recommended. © 2016 Wiley Periodicals, Inc.

The role and application of robotic surgery are debated, particularly given the expansion of laparoscopy, especially laparoendoscopic single-site (LESS) surgery. This cohort study was undertaken to delineate differences in outcomes between LESS and robotic distal pancreatectomy and splenectomy. With Institutional Review Board approval, patients undergoing LESS or robotic distal pancreatectomy and splenectomy from September 1, 2012, through December 31, 2014, were prospectively observed, and data were collected. The results are expressed as the median, with the mean ± SD. Thirty-four patients underwent a minimally invasive distal pancreatectomy and splenectomy: 18 with robotic and 16 with LESS surgery. The patients were similar in sex, age, and body mass index. Conversions to open surgery and estimated blood loss were similar. There were two intraoperative complications in the group that underwent the robotic approach. Time spent in the operating room was significantly longer with the robot (297 vs 254 minutes, P = .03), although operative duration (i.e., incision to closure) was not longer (225 vs 190 minutes; P = .15). Of the operations studied, 79% were undertaken for neoplastic processes. Tumor size was 3.5 cm for both approaches; R0 resections were achieved in all patients. Length of stay was similar in the two study groups (5 vs 4 days). There was one 30-day readmission after robotic surgery. Patient outcomes are similar with LESS or robotic distal pancreatectomy and splenectomy. Robotic operations require more time in the operating room. Both are safe and efficacious minimally invasive operations that follow similar oncologic principles for similar tumors, and both should be in the surgeon's armamentarium for distal pancreatectomy and splenectomy.

To date, the optimal surgical strategy for remnant gastric cancer has not been determined. The purpose of this study was to clarify the significance of lymphadenectomy with splenectomy in remnant gastric cancer surgery. This retrospective cohort study was conducted at the Kumamoto Regional Medical Center. The primary endpoint was overall survival after surgery. We retrospectively analyzed the clinicopathologic features, surgical treatments, and long-term prognosis of remnant gastric cancer patients treated with total gastrectomy. A total of 80 patients with gastric cancer in the remnant stomach after distal gastrectomy and who underwent total gastrectomy were enrolled in the study. Splenectomy was performed in 38 patients. Lymph node metastasis in the splenic hilum was not observed in the patients with pT1/pT2 tumors, whereas nodal metastasis at the splenic hilum was detected in 30.4% of the patients with pT3/pT4 tumors. The survival rate of the patients with pT3/pT4 tumors who underwent splenectomy was significantly higher than that of the patients who did not undergo splenectomy, although there was no difference in the patients with pT1/pT2 tumors. Among the patients classified as R0, the survival rate of the patients with pT3/pT4 tumors who underwent splenectomy was significantly higher than that of the patients who did not undergo splenectomy. Lymphadenectomy with splenectomy in radical surgery is beneficial for patients with advanced (pT3/pT4) remnant gastric cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

A considerable number of patients with portal hypertension (PHT) have to undergo splenectomy because they do not meet the requirements for liver transplantation (LT) or cannot find a suitable liver donor. However, it is not known whether pre-transplantation splenectomy may create occult difficulties for patients who require LT in future. We analyzed 1059 consecutive patients who underwent adult liver transplantation (ADLT). Patients with pre-transplantation splenectomy Sp(+) and without splenectomy Sp(-) were compared using a propensity score analysis to create the best match between groups. There were no differences between patients in group Sp(+) and group Sp(-) with respect to the main post-operative infections (12.20% vs. 15.85%, P = 0.455), and the incidence of major complications (6.10% vs. 10.98%, P = 0.264). The post-operative platelet count was significantly higher in group Sp(+) (P = 0.041), while group Sp(-) had a higher rate of post-operative thrombocytopenia (91.46% vs. 74.39%, P = 0.006) and early allograft dysfunction (EAD) (23.20% vs. 10.98%, P = 0.038). The 5-year overall survival rates were similar in groups Sp(-) and Sp(+) (69.7% vs. 67.6%, P = 0.701). Compared with Sp(-), the risk of infection and post-operative complications in group Sp(+) was not increased, while group Sp(-) had a higher rate of post-operative EAD. Moreover, pre-transplantation splenectomy is very effective for the prevention of thrombocytopenia after LT. Pre-transplantation splenectomy is recommended in cases with risky PHT patients without appropriate source of liver for LT.

We performed this study in adult patients with chronic primary immune thrombocytopenia to explore the long-term efficacy and safety of splenectomy. Data of 174 patients who underwent splenectomy in our hospital from 1994 to 2014 were analyzed. After splenectomy, 126 (72.4%) patients achieved a complete response (CR) and 28 (16.1%) achieved a response (R). Thirty-two (20.8%) responders relapsed with a median time of 24 months. Compared with non-responders and recurrent patients, the stable responders were younger and had higher preoperation and postoperation peak platelet count, later peak platelet count emergence time, and more megakaryocytes. Corticosteroid-dependent patients were more likely to response to splenectomy than those refractory to corticosteroid. We performed a relapse-free survival analysis among the 154 responders. In univariate analyses, corticosteroid dependent and time from diagnosis to splenectomy ≤24 months showed predictive value to persistent response. But only corticosteroid dependent was a significant predictor in multivariate analysis. The 30-d complication rate after the surgery was 25.9%. There were five (2.9%) patients experienced thrombosis and three (1.7%) refractory patients died during follow-up. Splenectomy was a safe treatment with a cure rate of 58.0%. Corticosteroid dependent showed predictive value to persistent response. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Splenectomy has been used in patients with common variable immunodeficiency disorders (CVID), mainly in the context of refractory autoimmune cytopenia and suspected lymphoma, but there are understandable concerns about the potential of compounding an existing immunodeficiency. With increasing use of rituximab as an alternative treatment for refractory autoimmune cytopenia, the role of splenectomy in CVID needs to be re-examined. This retrospective study provides the largest cohesive data set to date describing the outcome of splenectomy in 45 CVID patients in the past 40 years. Splenectomy proved to be an effective long-term treatment in 75% of CVID patients with autoimmune cytopenia, even in some cases when rituximab had failed. Splenectomy does not worsen mortality in CVID and adequate immunoglobulin replacement therapy appears to play a protective role in overwhelming post-splenectomy infections. Future trials comparing the effectiveness and safety of rituximab and splenectomy are needed to provide clearer guidance on the second-line management of autoimmune cytopenia in CVID. PMID:23480186

Idiopatic thrombocytopenic purpura (ITP) is the most common indication for splenectomy. The failure rate of surgery is about 8% and the failure rate after splenectomy is approximately 28% for all patients. When the presence of an accessory spleen is diagnosed, splenectomy is recommended. Laparoscopic approach is considered the first choice. At our Department, between July and November 2011 two patients underwent laparoscopic accessory splenectomy for recurrence of ITP. Both patients had a previously laparoscopic splenectomy. Preoperative Magnetic Resonance (MR) was performed in both the cases revealing the presence of an accessory spleen. The operative time was 105 and 100 minutes respectively. No perioperative complications occured. Hospital stay was four days in both cases. The first patient had a disease free period of two months; the second one of one month. Both patients restarted immunosuppressive therapy. The relapse of thrombocytopenia post-splenectomy can be associated with the presence of an accessory spleen. The laparoscopic accessory splenectomy should be considered the first choice approach. Surgical accessory splenectomy allows a transitory remission of the disease.

Full Text Available objective: To evaluate the follow-up of patients submitted to splenectomy with preservation of the upper splenic pole. Methods: All patients undergoing subtotal splenectomy were invited to be reviewed. A total of 86 patients submitted to this surgery were studied. The procedure was performed due to one of the following conditions: portal hypertension due to schistosomiasis (n = 43, trauma (n = 31, Gaucher’s disease (n = 4, myeloid hepatosplenomegaly due to myelofibrosis (n = 3, splenomegalic retarded growth and sexual development (n = 2, severe pain due to splenic ischemia (n = 2 and pancreatic cystadenoma (n = 1. All patients underwent hematologic tests, immunological assessment, abdominal ultrasonography, computed tomography (CT, scintigraphy and endoscopy. Rresults: Increased white blood cell and platelet counts were the only hematological abnormalities. No immune deficit was found. Esophageal varices were still present in patients who underwent surgery because of portal hypertension, but none had a re-bleeding event. The ultrasonography, tomography and scintigraphy confirmed the presence of functional splenic remnants without significant size alteration. Conclusions: Subtotal splenectomy seems to be a safe procedure that can be useful to treat conditions involving the spleen. The functions of the splenic remnants are preserved during long periods of time.

To evaluate whether dogs undergoing splenectomy had an increased risk of gastric dilatation-volvulus (GDV), compared with a control group of dogs undergoing enterotomy. Retrospective case-control study. 219 dogs that underwent splenectomy for reasons other than splenic torsion (splenectomy group; n = 172) or enterotomy (control group; 47) without concurrent gastropexy. Medical records were reviewed for information on signalment, date of surgery, durations of surgery and anesthesia, reason for splenectomy, histopathologic findings (if applicable), whether gastropexy was performed, duration of follow-up, and date of death (if applicable). Follow-up information, including occurrence of GDV, was obtained via medical records review and a written client questionnaire. Reasons for splenectomy included splenic neoplasia, nonneoplastic masses, infarction, traumatic injury, and adhesions to a gossypiboma. Incidence of GDV following surgery was not significantly different between dogs of the splenectomy (14/172 [8.1 %]) and control (3/47 [6.4%]) groups. Median time to GDV for the 17 affected dogs was 352 days (range, 12 to 2,368 days) after surgery. Among dogs that underwent splenectomy, sexually intact males had a significantly higher incidence of GDV (4/16) than did castrated males and sexually intact or spayed females (10/156). Incidence of GDV among sexually intact male dogs did not differ between groups. Results did not support a recommendation for routine use of prophylactic gastropexy in dogs at the time of splenectomy. Other patient-specific risk factors should be assessed prior to recommending this procedure.

Although most infections occur within the first 2 years after splenectomy, the relatively short follow-up reported in many studies may underestimate the frequency of infections. The objective of the study was to determine the incidence of infective outcomes and factors associated with infection after splenectomy by studying a group of patients who underwent splenectomy over a 10-year period. A retrospective and monocentric study of patients who underwent splenectomy between January 1st, 1997 and December 31st, 2004 in a French university hospital. Age, sex, indication for splenectomy, infectious events, death, vaccination and antibiotic prophylaxis were collected in January 2015. One hundred and sixty-five patients were included. The most common reasons for splenectomy were therapeutic hematological indications (37.5%). Ninety-seven per cent received pneumococcal vaccine. Prophylactic antibiotics were prescribed in 78% of patients. Thirty-seven patients had 42 severe infections with a median incidence rate of 4 years after splenectomy (2 days-12 years). The rate of infection after splenectomy declined over time but 57% occurred after 2 years and 14.3% after 10 years. Respiratory infections were the most common sites of infections. The incidence of infection differed according to age was highest among the elderly (HR=6.2; 95%CI: 1.4-27.1; after 65 years old) and underlying reason for splenectomy (P=0.02). There is no difference with or without prophylactic antibiotics. After splenectomy, the incidence of severe infection declined over time but can occur after 10 years. The onset of infection is linked to age and reason for splenectomy. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Splenectomy for solitary splenic metastasis of ovarian cancer

Koh, Yang Seok; Kim, Jung Chul; Cho, Chol Kyoon

2004-01-01

Splenic metastases occur in rare cases with a few case reports of patients in the literature. Generally, splenic metastases mean late dissemination of a disease. Solitary splenic metastases from solid tumors are extremely unusual. We report a case of a patient with ovarian mucinous cystadenocarcinoma who underwent splenectomy for isolated parenchymal metastasis. Ovarian epithelial tumors comprised most of isolated splenic metastases from gynecologic tumor. When isolated splenic recurrence is suspected on image studies and serum tumor markers, intraabdominal gross findings should be examined to exclude peritoneal carcinomatosis. If only spleen was under suspicion of recurrence of ovarian cancer, splenectomy may play a therapeutic role

Evans syndrome (ES) is a rare disease characterized by simultaneous or sequential development of autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP) with or without immune neutropenia. Splenectomy is one of the treatment options for disease refractory to medical therapy. Venous thromboembolism (VTE) following splenectomy for hematological diseases has an incidence of 10%. Here we describe a case report of a young patient hospitalized with severe hemolytic anemia with Hgb 4.8 g/dl. He developed thrombocytopenia with platelet nadir of 52,000/mm 3 , thus formally diagnosed with ES. He failed standard medical therapy. He underwent splenectomy and had a fatal outcome. Autopsy confirmed the cause of death as pulmonary embolism (PE). This case report and review of the literature highlight important aspects of the association between VTE, splenectomy, and hemolytic syndromes including the presence of thrombocytopenia. The burden of the disease is reviewed as well as various pathophysiologic mechanisms contributing to thromboembolic events in these patients and current perioperative prophylactic anticoagulation strategies. Despite an advancing body of literature increasing awareness of VTE following splenectomy, morbidity and mortality remains high. Identifying high risk individuals for thromboembolic complications from splenectomy remains a challenge. There are no consensus guidelines for proper perioperative and post-operative anti-coagulation. We encourage future research to determine which factors might be playing a role in increasing the risk for VTE in real time with hope of forming a consensus to guide management.

2002-01-01

Objective: To study the effect of splenectomy on serum β-amyloid (Aβ) levels in rabbit. Methods: Thirty 3yr-old rabbits underwent splenectomy and fifteen others underwent a sham-operation of laparectomy only. Serum Aβ levels were determined with RIA before and at regular intervals after operation. Results: In the splenectomy group, the Aβ levels were increased greatly after the operation and reached the peak at 5 th week. The levels then gradually declined but remained significantly higher than the pre-operative value at 6 th month. In the sham operation group, the value was no drastically changed but increased slowly (as an aging process). Conclusion: Splenectomy in rabbit would markedly increase the serum Aβ level, possibly due to a hypoimmune state impairing clearance of the substance

Abstract The spleen is a crucial organ in humans. Little is known about the association between stroke and splenic injury or splenectomy. The aim of this study was to determine the risk of stroke in patients with splenic injury and splenectomy. A nationwide cohort study was conducted by analyzing the National Health Insurance Research Database in Taiwan. For comparison, control patients were selected and matched with splenic injury patients in a ratio of 4:1 according to age, sex, and the year of hospitalization. We analyzed the risks of stroke using a Cox proportional-hazards regression analysis. A total of 11,273 splenic injury patients, including 5294 splenectomized and 5979 nonsplenectomized patients, and 45,092 control patients were included in this study. The incidence rates of stroke were 8.05, 6.53, and 4.25 per 1000 person-years in splenic injury patients with splenectomy, those without splenectomy, and the control cohort, respectively. Compared with the control cohort, splenic injury patients with splenectomy exhibited a 2.05-fold increased risk of stroke (95% confidence interval [CI] 1.8–2.34), whereas those without splenectomy exhibited a 1.74-fold increased risk (95% CI 1.51–2). Splenectomy entailed an additional 1.21-fold increased risk of stroke compared with nonsplenectomy in patients with splenic injury. This study revealed that splenic injury and splenectomy were significantly associated with an increased risk of hemorrhagic and ischemic strokes. The results of this study may alert physicians and patients to the complications of splenic injury and splenectomy. PMID:26334909

Medical complications following splenectomy.

Buzelé, R; Barbier, L; Sauvanet, A; Fantin, B

2016-08-01

Splenectomy is attended by medical complications, principally infectious and thromboembolic; the frequency of complications varies with the conditions that led to splenectomy (hematologic splenectomy, trauma, presence of portal hypertension). Most infectious complications are caused by encapsulated bacteria (Meningococcus, Pneumococcus, Hemophilus). These occur mainly in children and somewhat less commonly in adults within the first two years following splenectomy. Post-splenectomy infections are potentially severe with overwhelming post-splenectomy infection (OPSI) and this justifies preventive measures (prophylactic antibiotics, appropriate immunizations, patient education) and demands prompt antibiotic management with third-generation cephalosporins for any post-splenectomy fever. Thromboembolic complications can involve both the caval system (deep-vein thrombophlebitis, pulmonary embolism) and the portal system. Portal vein thrombosis occurs more commonly in patients with myeloproliferative disease and cirrhosis. No thromboembolic prophylaxis is recommended apart from perioperative low molecular weight heparin. However, some authors choose to prescribe a short course of anti-platelet medication if the post-splenectomy patient develops significant thrombocytosis. Thrombosis of the portal or caval venous system requires prolonged warfarin anticoagulation for 3 to 6 months. Finally, some studies have suggested an increase in the long-term incidence of cancer in splenectomized patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Portal and/or splenic vein thrombosis (PSVT) is common after splenectomy. It can be a life-threatening complication, with a risk of bowel ischemia and portal hypertension. An early diagnosis allows an effective medical treatment and prevents life-threatening complications. There is no consensus regarding the benefit of systematic screening of patients after splenectomy for PSVT. We started in January 2012 a routine screening of PSVT after elective splenectomy. The aim of this study was to assess this policy. Since January 2012, all patients undergoing an elective splenectomy had an abdominal CT-scan on postoperative-day 7. Demographic data, pathology, type of surgery, platelet counts before and after surgery, outcome, results of medical imaging, and management of PSVT and its results were recorded. Over 3 years, 52 patients underwent an elective splenectomy. All of them had a CT-scan at postoperative-day 7. A PSVT was found in 11 patients (21.2 %). They were all asymptomatic. Lymphoma and splenomegaly were the main factors associated with PSVT in the univariate analysis. All patients with PSVT were treated with anticoagulation and no complication of PSVT occurred. The follow-up CT confirmed the efficacy of anticoagulation therapy in all patients. Routine screening of PSVT after elective splenectomy is warranted because it allows to start anticoagulant therapy and avoid further life-threatening complications. The incidence of PSVT is particularly high among patients operated on for lymphoma or with splenomegaly. Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

The treatment of choice in steroid-resistant immune thrombocytopenia is still controversial due to the recent advent of new drugs (anti-CD20 antibodies and thrombopoietin mimetics) that have encouraged a generalized tendency to delay splenectomy. Consequently, it is extremely importance to define the efficacy and safety of splenectomy in the long term. We retrospectively analyzed the data of 233 patients affected by immune thrombocytopenia who underwent splenectomy between 1959 and 2001 in 6 European hematologic institutions and who have now a minimum follow up of ten years from surgery. Of the 233 patients, 180 (77%) achieved a complete response and 26 (11%) a response. Sixty-eight of 206 (33%) responsive patients relapsed, mostly (75%) within four years from first response. In 92 patients (39.5%), further treatment was required after splenectomy that was effective in 76 cases (83%). In 138 patients (59%), response was maintained free of any treatment at last contact. No significant association between baseline characteristics and likelihood of stable response was found. Overall, 73 (31%) and 58 (25%) patients experienced at least one infectious or hemorrhagic complication, which was fatal in 2 and 3 patients, respectively. A stable response to splenectomy was associated with a lower rate of infections (P=0.004) and hemorrhages (PSplenectomy achieved a long-term stable response in approximately 60% of cases. Complications mainly affected non-responding patients and were fatal in a minority. PMID:23144195

The spleen is a crucial organ in humans. However, little is known about the association of venous thromboembolism (VTE) with splenic injury and splenectomy in trauma patients. The aim of this study was to determine the subsequent risk of VTE following splenic injury and splenectomy. A nationwide retrospective cohort study was conducted by analysing data from the National Health Insurance Research Database in Taiwan. We included 6,162 splenic injury patients (3,033 splenectomised and 3,129 nonsplenectomised patients) and 24,648 comparison patients who were selected by frequency match based on sex, age, and the index year during 2000-2006. All patients were followed until the occurrence of VTE, 31 December, 2011, death, or withdrawal from the insurance program. The age of patients with splenic injury was 41.93 ± 16.44 years. The incidence rates of VTE were 11.81, 8.46, and 5.21 per 10,000 person-years in the splenic injury patients with splenectomy, splenic injury patients without splenectomy, and comparison patients, respectively. Compared with the comparison cohort, splenic injury patients with splenectomy exhibited a 2.21-fold risk of VTE (95% confidence interval [CI], 1.43-3.43), whereas those without splenectomy exhibited a 1.71-fold risk of VTE (95% CI, 1.05-2.80). The overall incidence rate of VTE was 1.97-fold higher in the splenic injury cohort than the comparison cohort (95% CI, 1.38-2.81). Although splenectomy increased the risk of VTE 1.35-fold compared with no splenectomy, the difference was not statistically significant (95% CI, 0.74-2.45). These results may alert physicians and patients to the complications of splenic injury and splenectomy.

The outcomes of children with congenital hemolytic anemia (CHA) undergoing total splenectomy (TS) or partial splenectomy (PS) remain unclear. In this study, we collected data from 100 children with CHA who underwent TS or PS from 2005–2013 at 16 sites in the Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium using a patient registry. We analyzed demographics and baseline clinical status, operative details, and outcomes at 4, 24, and 52 weeks after surgery. Results were summarized as hematologic outcomes, short-term adverse events (AEs) (≤ 30 days after surgery), and long-term AEs (31–365 days after surgery). For children with hereditary spherocytosis, after surgery there was an increase in hemoglobin (baseline 10.1 ± 1.8 gm/dl, 52 week 12.8 ± 1.6 gm/dl; mean ± SD), decrease in reticulocyte and bilirubin as well as control of symptoms. Children with sickle cell disease had control of clinical symptoms after surgery, but had no change in hematologic parameters. There was an 11% rate of short-term AEs and 11% rate of long-term AEs. As we accumulate more subjects and longer follow-up, use of a patient registry should enhance our capacity for clinical trials and engage all stakeholders in the decision-making process.

Splenectomy is controversial in acute hemorrhagic shock models. To compare splenectomized (SP) versus sham-splenectomized (SSP) swine during acute controlled hemorrhage. Twenty-six male Landrace White swine (mean body weight ± standard deviation, 33.8 ± 2.9 kg) were used. Ethics approval was obtained. Landrace swine underwent splenectomy (n = 13) or sham-splenectomy (n = 13), were bled to mean arterial blood pressure (MAP) of 40 mm Hg, which was held for 60 min, given 125 mL IV RescueFlow, held for a further 60 min, given whole blood, and held for a final 60 min. Tissue oxygen saturation, thromboelastography, oncotic pressure, urine volume and specific gravity, complete blood count, serum chemistry, body temperature, hematocrit, total solids, arterial and mixed venous blood gas, bispectral index, SAP, MAP, DAP, cardiac index, total blood volume (TBV) removed and returned, rate of hemorrhage and transfusion, spleen weight, heart rate (HR), arterial pH, lactate, PaO2, PaCO2, respiratory rate, cranial mesenteric and renal artery blood flow were recorded. Groups were compared using two-way ANOVA with post hoc Bonferroni (P splenectomy for the duration of the experiment (P splenectomy (P Splenectomy likely accounts for the transient increase in hematocrit and the higher HR in SP swine prior to hemorrhage, and the differences in TBV removed between the two groups during hemorrhage. With a fixed end point model using a moderate rate of acute hemorrhage and an MAP of 40 mm Hg, splenectomy is not necessary and may confound results.

Splenectomy is a well-recognised risk factor for life-threatening overwhelming post-splenectomy infection (OPSI). To prevent OPSI, immunisations against encapsulated bacteria (S. pneumoniae, N. meningitidis, H. influenzae) and influenza virus are recommended. However, there is still a lack of uniformity and poor compliance with these recommendations. Following a local physicians' awareness campaign regarding the importance of vaccine prophylaxis of splenectomised patients, we aimed to register vaccination coverage, mortality and infection rates in all patients who underwent splenectomy at our hospital, over a six-year time span. Reasons for splenectomy, patients' compliance with vaccinations, mortality and infectious events were recorded. The reasons for splenectomy in the 216 identified patients (mean age 58.2 ± 14; M:F ratio 1.4:1) were haematologic disorders (38.8%), solid tumours (28.7%), traumatic rupture (22.7%) and other causes (9.7%). A total of 146 patients (67.6%) received at least one of the four vaccines. Overall, the mortality rate was significantly greater in unvaccinated compared to vaccinated patients (p splenectomy the statistical significance was lost (p = 0.085) due to the burden of solid tumour-related mortality. Among the 21 reported cases of OPSI, eight were fatal and five were potentially vaccine-preventable. Our results show that two-thirds of splenectomised patients comply with vaccine prophylaxis. Future interventional studies or ad hoc registries might overcome barriers to vaccination or intentional non-compliance.

Splenectomy is the definitive second-line therapy for refractory immune thrombocytopenic purpura (ITP), and has a reported response rate of 50-80%. Medical attention should be reconsidered when there is no evidence of accessory spleen in refractory ITP patients after splenectomy. The purpose of this study was to determine whether platelet count evolution differs between patients with a successful or unsuccessful result after splenectomy for ITP. Archived records of 104 consecutive patients that underwent splenectomy for ITP were reviewed. Patients were divided into two groups (failures and successes) using a final follow-up platelet count of 100,000/μL as a cut-off. Platelet count evolutions in these two groups were compared using the Student's t test. Successes and failures were found to have significantly different platelet counts from two days postoperatively (P = 0.016). The area under the receiver operating characteristic curve was 0.630 (95% confidence interval, 0.518-0.741, P = 0.030), and when a cut-off value of 100,000/μL was used, sensitivity and specificity were 68.2 and 51.2%, respectively. To obtain positive and negative predictive values exceeding 50%, additional platelet counts were required at one week and one month after splenectomy. We propose a protocol for ITP follow-up after splenectomy.

The purpose of this research is to study the outcomes of splenectomy for chronic and persistent immune thrombocytopenia (ITP). This study is a retrospective analysis of 254 patients with chronic or persistent ITP who underwent splenectomy at CMC, Vellore, India between 1995 and 2009. Responses were assessed based on standard criteria. One hundred and sixty seven adults and 87 children with a median age of 29 years (range 2-64) with persistent (n = 103) or chronic ITP (n = 151) was studied. Response was seen in 229 (90.2 %) including CR in 74.4 % at a median time of 1 day (range 1-54). Infections following splenectomy were reported in 16 %. Deaths related to post splenectomy sepsis occurred in 1.57 % and major bleeding in 0.78 %. At median follow-up of 54.3 months (range 1-290), 178 (70.1 %) remain in remission. The 5-year and 10-year overall survival (OS) is 97.4 ± 1.2 % and 94.9 ± 2.1 %, respectively, while the 5-year and 10-year event-free survival (EFS) is 76.5 + 2.9 % and 71.0 + 3.9 %, respectively. Splenectomy is associated with long-term remission rates of >70 % in chronic or persistent ITP.

BACKGROUND: Post-splenectomy infection has a mortality rate of up to 70%. Previously we have published data confirming the poor adherence to best practice guidelines with relation to management of the asplenic patient. A defined protocol of care was established, staff education commenced and a \\'patient information leaflet\\' made available. AIM: To ascertain whether management of the asplenic patient has improved since the implementation of a structured programme of care. METHOD: Retrospective chart review of all splenectomies performed in Beaumont Hospital between 2002 and 2008. RESULTS: Overall, 75.9% of patients were documented as having received the recommended vaccinations. Of these, 48.7% were not timed according to recommended guidelines. Prophylactic antibiotics were documented as prescribed in all but five patients discharged. CONCLUSIONS: These results demonstrate an improvement in post-splenectomy care between 2002 and 2008. However, further improvements are necessary.

Full Text Available INTRODUCTION : Laparoscopic splenectomy (LS is an accepted procedure for elective splenectomy. Advancement in technology has extended the possibility of LS in massive splenomegaly [Choy et al., J Laparoendosc Adv Surg Tech A 14(4, 197-200 (2004], trauma [Ren et al., Surg Endosc 15(3, 324 (2001; Mostafa et al., Surg Laparosc Endosc Percutan Tech 12(4, 283-286 (2002], and cirrhosis with portal hypertension [Hashizume et al., Hepatogastroenterology 49(45, 847-852 (2002]. In a developing country, these advanced gadgets may not be always available. We performed LS using conventional and reusable instruments in a public teaching the hospital without the use of the advanced technology. The technique of LS and the outcome in these patients is reported. MATERIALS AND METHODS : Patients undergoing LS for various hematological disorders from 1998 to 2004 were included. Electrocoagulation, clips, and intracorporeal knotting were the techniques used for tackling short-gastric vessels and splenic pedicle. Specimen was delivered through a Pfannensteil incision. RESULTS : A total of 26 patients underwent LS. Twenty-two (85% of patients had spleen size more than 500 g (average weight being 942.55 g. Mean operative time was 214 min (45-390 min. The conversion rate was 11.5% ( n = 3. Average duration of stay was 5.65 days (3-30 days. Accessory spleen was detected and successfully removed in two patients. One patient developed subphrenic abscess. There was no mortality. There was no recurrence of hematological disease. CONCLUSION : Laparoscopic splenectomy using conventional equipment and instruments is safe and effective. Advanced technology has a definite advantage but is not a deterrent to the practice of LS.

Immune thrombocytopenic purpura (ITP) is a common hematological disease treated primarily by corticosteroids. The aim of the present study was to compare response rate between patients, underwent splenectomy vs. rituximab as second-line therapy. Adult patients diagnosed with ITP who did not respond to corticosteroids or relapsed during the period 1990-2014 were included in a quasi-experimental study. Categorical variables were compared using Fisher exact test. Response to treatment was compared using logistic regression. Data were analyzed using SAS V9.2. One-hundred and forty-three patients with ITP were identified through medical records. Of 62 patients treated, 30 (48.38%) required second-line therapy. 19 (63%) patients received rituximab, and 11 (37%) underwent splenectomy. Platelets at diagnosis were not different between study groups (p = 0.062). Splenectomy group patients were younger (p = 0.011). Response to second-line therapy showed no significant difference between two groups (OR 2.03, 95% CI (0.21-22.09), p = 0.549). Results did not show a statistically significant difference in platelet counts over time between treatment groups (p = 0.101). When used exclusively as a second-line therapy for steroid-refractory ITP, the response rate was not statistically different between rituximab and splenectomy. However, further large studies are needed to assess the response rates for these treatment modalities as a second-line therapy.

Laparoscopic Splenectomy for Traumatic Splenic Injury after Screening Colonoscopy

Full Text Available Colonoscopy is a widespread diagnostic and therapeutic procedure. The most common complications include bleeding and perforation. Splenic rupture following colonoscopy is rarely encountered and is most likely secondary to traction on the splenocolic ligament. Exploratory laparotomy and splenectomy is the most commonly employed therapeutic intervention for this injury reported in the literature. We present the case of a patient with this potentially fatal complication who was treated successfully at our institution. To our knowledge it is the first report in the literature of laparoscopic splenectomy as a successful minimally invasive treatment of splenic rupture following colonoscopy. The patient was a 62-year-old female who underwent screening colonoscopy with polypectomies at the cecum, descending colon and rectum. Immediately following the procedure she developed abdominal pain and had a syncopal episode. Clinical, laboratory and imaging findings were suggestive of hemoperitoneum and a ruptured spleen. A diagnostic laparoscopy was emergently performed and revealed a grade IV splenic laceration and hemoperitoneum. Laparoscopic splenectomy was completed safely and effectively. The patient’s postoperative recovery was uneventful. We conclude that splenic rupture after colonoscopy is a rare but dangerous complication. A high index of suspicion is required to recognize it early. Awareness of this potential complication can lead to optimal patient outcome. Laparoscopic splenectomy may be a feasible treatment option.

Full Text Available Background : In this study, we show the advantages of partial splenectomy (PS over total splenectomy (TS regarding the chances of overwhelming postsplenectomy sepsis (OPSI. Materials and Methods: From February 1991 to December 1999, 143 cases of β-thalassemia underwent PS. 1/3, 1/4 of the splenic tissue was preserved. One hundred and ten cases were followed for an average of 5 years. None of the patients received vaccination or prophylactic antibiotics. Pre- and postoperative hematological profiles, IgM levels, recurrence of hypersplenism and septic episodes were compared among the data of 60 cases TS; all these cases have been operated in the same hospital. Results: Hematological profile significantly increased and transfusion requirement approximately reduced to three-fold. After 3 years, 22.7% in PS and 13.3% in TS groups required the same amount of preoperative transfusion. After 5 years, these percentages were 27.3 and 18.3%, respectively. Two patients in PS and six in TS group developed signs of sepsis. Conclusion : Vaccination or prophylactic antibiotics are not necessary after PS. The risk of sepsis in PS without antibiotics is less than that in TS with antibiotics, and resplenectomy after PS is not associated with serious complications.

Full Text Available Dysbiosis of gut microbiota and metabolome is a frequently encountered condition in liver cirrhosis (LC patients. The severity of liver dysfunction was found to be correlated with the degree of microbial dysbiosis. Several clinical studies have indicated liver function improvement after therapeutic splenectomy for LC-induced hypersplenism. We sought to determine whether such post-splenectomy outcome is pertinent to modulation of the abnormal gut microenvironment in LC patients. A cross-sectional study including 12 LC patients and 16 healthy volunteers was first conducted, then a before–after study in the cohort of patients was carried out before and 6 months after splenectomy. Fecal samples were collected in hospital. Temporal bacterial (n = 40 and metabolomics (n = 30 profiling was performed using 16s rRNA gene sequencing and ultra performance liquid chromatography/mass spectrometer (UPLC/MS, respectively. Our results revealed that microbial composition in patients was clearly different from that in healthy controls (HCs, evidenced by considerable taxonomic variation. Along with improved liver function (Child–Pugh score, the patients also displayed similar gut microbiota profile and predicted metagenome function to that of HCs after splenectomy. Enterobacteriaceae and Streptococcaceae, two LC-enriched families showing positive relation with Child–Pugh score, exhibited significantly decreased abundance after splenectomy. At the genus level, 11 genera were differentially abundant between patients and HCs, but 9 genera of them restituted to normal levels by certain degree after splenectomy. PICRUSt analysis showed that the relative abundance of 17 KEGG pathways was partially restored after splenectomy. Four of them were amino acid-related pathways: lysine degradation, tryptophan degradation, amino acid metabolism, and protein digestion and absorption. These findings were supported by metabonomics results which showed that relative abundance

Splenectomy is the standard therapy for medically refractory immune thrombocytopenia (ITP). Laparoscopic splenectomy (LS) has gained wide acceptance; however, the long-term outcomes of LS versus open splenectomy (OS) for patients with ITP remain unclear. We analyzed, retrospectively, 32 patients who underwent splenectomy, as LS in 22 and OS in 10, for refractory ITP at our institute. Data were evaluated based on the American Society of Hematology 2011 evidence-based practice guidelines for ITP. Although the operation time was significantly longer in the LS group (p < 0.01), LS was associated with less blood loss (p < 0.01), infrequent blood transfusion during surgery (p < 0.01), quicker resumption of oral intake (p < 0.01), and shorter hospital stay (p < 0.01) than OS. Positive responses, including complete and partial remission, were achieved in 90% of the OS group patients and 77% of the LS group patients. The mean follow-up periods were 183 and 92 months, respectively. Relapse-free survival rates, 15 years after the operation were 63% in the OS group and 94% in the LS group. LS can provide better short-term results and comparable long-term results to those of OS for ITP.

Monteiro, M.E.; Verhaeghe, R.; Devos, P.

Platelet survival combined with surface counting was performed in 9 patients with idiopathic thrombocytopenic purpura, resistent to steroid therapy. All patients had a markedly enhanced platelet turnover, five of them showed an augmented trapping of radioactivity over the spleen compared to liver and heart. These five patients underwent splenectomy: the platelet count increased in all of them but this increase was not always sustained. (Author) [pt

Objectives Little is known about the risk of pyogenic liver abscess in patients with splenectomy. We explored the relationship between splenectomy and pyogenic liver abscess in Taiwan. Methods We conducted a nationwide cohort analysis using the hospitalization dataset of the Taiwan National Health Insurance Program. We included 17 779 subjects aged 20–84 years who underwent splenectomy in 1998 to 2010 (splenectomy group) and 70 855 randomly selected subjects without splenectomy (non-splenectomy group). Both groups were matched by sex, age, other comorbidities, and hospitalization year of receiving splenectomy. The incidence of pyogenic liver abscess at the end of 2011 was measured. The multivariable Cox proportional hazard regression model was used to estimate the hazard ratios and 95% confidence intervals for pyogenic liver abscess associated with splenectomy and other comorbidities. Results The overall incidence rate was 3.75-fold higher in the splenectomy group than that in the non-splenectomy group (2.15 vs 0.57 per 1000 person-years; 95% confidence interval, 3.57–3.94). After controlling for potential confounding factors, the adjusted hazard ratio of pyogenic liver abscess was 3.89 in subjects with splenectomy (95% confidence interval, 3.20–4.72) when compared with subjects without splenectomy. In further analysis, the hazard ratio markedly increased to 14.34 for those with splenectomy and having any of the assessed comorbidities, including alcoholism, biliary stone, chronic kidney disease, chronic liver diseases, and diabetes mellitus (95% confidence interval, 10.61–19.39). Conclusions Patients with splenectomy are at an increased risk of developing pyogenic liver abscess, particularly when they have comorbid conditions. PMID:26256773

Effect of splenectomy in patients with haemopoietic diseases on the thrombocytopoietic activity of sera (ATS)

Sylwestrowicz, T.; Sokolowska, K.; Szczepanik, A.; Pawelski, S.

1981-01-01

Thrombocytopoietic activity (ATS) was determined in tests on mice on the day before and on the 1st, 7th and 14th days after splonectomy in 18 patients (13 with idiopathic thrombocytopenia, 5 with haemolytic anaemia). It was found that in patients with ITP and high-grade splenic destruction of platelets ATS increased on the first days after splenectomy. On the other hand, in ITP patients with low-grade splenic platelet destruction splenectomy decreased the value of ATS immediately after the operation. Splenectomy performed in cases with normal platelet count caused no greater changes in ATS in the first week. These observations suggest that in patients with increased splenic destruction of platelets ATS may be inhibited and this inhibition may be removed after splenectomy. Absent correlation between ATS and platelet count may indicate that the value of ATS is not of decisive importance in thrombocytopenia regression following splenectomy. (author)

Splenectomy may be necessary to treat systemic lupus erythematosus (SLE) patients with thrombocytopenia; however, whether performing a splenectomy on patients without SLE increases the subsequent risk of SLE remains unknown. Therefore, this study was conducted to determine the association between splenectomy and SLE. We conducted a cohort study by using data from the Taiwan National Health Institute Research Database to identify 10,298 patients with received a splenectomy between 2000 and 2006 and 41,192 participants without received a splenectomy who were selected by frequency matched based on sex, age, and the index year. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95 % confidence intervals (CIs) of developing SLE associated with splenectomy compared with patients who did not receive a splenectomy. During the study period, the overall incidence density rate of SLE was higher in the splenectomy cohort than in the non-splenectomy cohort (adjusted HR 10.55; 95 % CI 50.55-20.05). The incidence density rates of SLE in women and men who received a splenectomy were higher than those of patients who did not receive a splenectomy. Non-traumatic splenectomy increases the subsequent risk of SLE. The risk of SLE should be considered before performing a splenectomy, particularly in women and younger patients.

The aim this study was to estimate the appearance of abscesses after splenonectomy in patients with gastric and cardia cancer after surgical treatment. Between June 1996 and December 2002, 75 splenectomies were performed during the surgical treatment of gastric cancer (52% pts) and cardia cancer (48%). The studied group included 58 men (77%) and 17 women (23%), aged from 48 to 72 years. The surgical treatment was paliative in 9% of patients while 91% underwent radical operation. 93.33% of the splenectomies were performed due to oncological reasons, 6.6% due to ' technical ' reasons. The studied group included 20% patients with grade I of progression, 20% in grade II, 37% in III and 23% in IV grade. The overall rate of specific complications in patients after surgical treatment due gastric and cardia cancer was 24.8%. Abscesses after splenectomies were observed in 9.33% of patients (7/75 pts). The study has shown no statistically significant differences (p≥ 0.005) regarding all the analyzed parameters (age, grade of progression, nutritioron, etc.) in patients with abscesses, as compared to the control group without abscesses. The overall mortality was estimated to be 2.66%, and 14.33% for patients with abscesses after splenectomy. The most frequent isolated pathogenes were: S. epidermidis MRS, C. albicans, E. faecium, P. aeruginosa. The duration of hospitalization in patients with observed abscesses was estimated to be 55 days (relaparotomy) and 45.5 days (percutaneous drainage). In patients with gastric and cardia cancer undergoing surgical treatment with splenectomy all analyzed the parameters (age, grade of progression, period of drainage, malnutrition, used antibiotics in prophylaxy) were not statistically significant in regard to the appearance of abscesses after splenectomies. Percutaneous drainage with ultrasound control is recommended in treatment of abscesses after splenectomies. (author)

This study aimed to determine the effect of fibrin glue and polyglycolic acid (PGA) felt on prevention of pancreatic fistula (PF) after laparoscopic splenectomy in patients with hypersplenism due to liver cirrhosis. Fifty consecutive patients were enrolled in this prospective study. Twenty-three patients underwent laparoscopic splenectomy with a fibrin sheet (fibrin sheet group). The sealing ability of each treatment was evaluated by an ex vivo pressure test model. Based on the results from ex vivo experiments, 27 patients received prophylaxis using fibrin glue and PGA felt (PGA with fibrin group). The primary endpoint was the incidence of PF. Significantly more (5, 22%) patients developed PF in the fibrin sheet group than in the PGA with fibrin group (0%, P = .037). Our new application of fibrin glue and PGA felt is an effective prophylactic procedure for preventing development of PF after laparoscopic splenectomy. Copyright © 2016 Elsevier Inc.

Full Text Available Idiopathic thrombocytopaenic purpura (ITP patients are at high risk for complications during and after cardiac surgeries involving cardiopulmonary bypass. The main clinical problem of primary ITP is an increased risk of bleeding although bleeding may not always be present. More recently, thrombosis has become appreciated as another potential complication of the procedure. We report a 22-year-old female patient with ITP with bicuspid aortic valve and splenomegaly, who underwent uncomplicated aortic valve replacement and splenectomy simultaneously. She was readmitted with chest pain due to coronary thrombosis following splenectomy which made the management difficult. We describe our experience in managing this patient who presented with thrombotic complication rather than bleeding in post-operative period and the challenges met in maintaining appropriate anticoagulation for aortic valve replacement as well as thrombosis, post-splenectomy

Non-cirrhotic portal hypertension was first described by Guido BANTI in 1898 as a condition characterized by the association of portal hypertension with splenomegaly, anemia and healthy liver. The diagnosis was based on abdominal ultrasound, splenoportography and liver biopsy. Our study aimed to evaluate the role of splenectomy in non-cirrhotic portal hypertension. We conducted a retrospective study of 3 patients (2 women and 1 man) treated by our staff over the period January 2010 -September 2016. The diagnosis of idiopathic portal hypertension was based on the following criteria: portal hypertension, the presence of oesophageal varices associated with splenomegaly, the absence of cirrhosis or of other liver disorders responsible of portal hypertension. All patients underwent splenectomy. Outcome after splenectomy was marked by the standardization of clinical, radiological and biological signs of this disease associated with the absence of oesophageal varices recurrence. Splenectomy associated with ligation of oesophageal varices may be sufficient to treat this syndrome and especially its consequences without using splenorenal bypass.

Following a splenectomy patients are at increased risk of significant infections. In its most severe form, overwhelming post-splenectomy infection (OPSI) has a mortality rate of up to 80%. In this study we aim to establish the adherence to vaccination and antibiotic national guidelines in splenectomised patients. A retrospective study of 100 patients who underwent splenectomy (21 emergency, 79 elective), in two teaching hospitals was undertaken over a five-year period. Patients were followed up for five years. Hospital and GP records were reviewed for adherence to pre, intra and postoperative vaccination, thromboprophylaxis and antibiotic guidance. Eighty-six eligible patients (91.5%) received their Haemophilus influenzae B, meningococcal C and pneumococcus vaccinations peri-operatively. Eighty-one (86%) received post-operative antibiotics. Ninety-nine percent of patients received thromboprophylaxis treatment. Eighty-nine (95%) were treated with long-term antibiotic prophylaxis. Only 20 patients (23%) had an emergency supply of antibiotics. Ninety-five percent of patients were administered an annual influenza vaccination and 84% of eligible patients received a five-year pneumococcal booster vaccination. Improvement in the management of this patient cohort can be achieved by a multidisciplinary approach involving adherence to national guidelines, standardised trust protocols, patient information leaflets and advice detailing risk of infection, standardised GP letters and a splenectomy register to monitor and manage this vulnerable group of patients.

Full Text Available AJ Jolanda LammersDepartment of Infectious diseases, Tropical Medicine and AIDS, Academic Medical Center, Amsterdam, The NetherlandsAbstract: Although spleen preservation surgery and non-operative management are first-line treatment options, total splenectomy is frequently performed. Splenectomy is performed for a number of indications including idiopathic thrombocytopenic purpura, high-energetic trauma, and hematological malignancy. Following splenectomy, patients are at risk for overwhelming post-splenectomy infection (OPSI, a syndrome that presents with mild symptoms at onset but irreversible multi-organ-failure occurs within hours to days. Since the spleen plays an important role in the immune response to polysaccharide antigens, encapsulated bacteria such as pneumococci are the most frequently described causative organisms of OPSI. Although the incidence of OPSI is low, the associated mortality is reported to be as high as 80%. Because of the overwhelming and frequently irreversible nature of this syndrome, prophylactic measures to prevent OPSI have been recommended. These recommendations include vaccination, use of antibiotics, and continuous patient education. After splenectomy, patients should receive immunizations against the encapsulated bacteria S. pneumoniae, H. influenza, and N. meningitidis. Antibiotic therapy should include prophylaxis as well as “on-demand” antibiotics when infection is suspected. Importantly, patients should receive ongoing education regarding the risks associated with asplenia and precautions to take when infection occurs and when traveling.Keywords: S. pneumoniae, sepsis, splenectomy, vaccination

The spleen is a crucial organ in humans. Little is known about the association between stroke and splenic injury or splenectomy. The aim of this study was to determine the risk of stroke in patients with splenic injury and splenectomy.A nationwide cohort study was conducted by analyzing the National Health Insurance Research Database in Taiwan. For comparison, control patients were selected and matched with splenic injury patients in a ratio of 4:1 according to age, sex, and the year of hospitalization. We analyzed the risks of stroke using a Cox proportional-hazards regression analysis.A total of 11,273 splenic injury patients, including 5294 splenectomized and 5979 nonsplenectomized patients, and 45,092 control patients were included in this study. The incidence rates of stroke were 8.05, 6.53, and 4.25 per 1000 person-years in splenic injury patients with splenectomy, those without splenectomy, and the control cohort, respectively. Compared with the control cohort, splenic injury patients with splenectomy exhibited a 2.05-fold increased risk of stroke (95% confidence interval [CI] 1.8-2.34), whereas those without splenectomy exhibited a 1.74-fold increased risk (95% CI 1.51-2). Splenectomy entailed an additional 1.21-fold increased risk of stroke compared with nonsplenectomy in patients with splenic injury.This study revealed that splenic injury and splenectomy were significantly associated with an increased risk of hemorrhagic and ischemic strokes. The results of this study may alert physicians and patients to the complications of splenic injury and splenectomy.

Immune thrombocytopenic purpura (ITP) results from accelerated platelet destruction mediated by autoantibodies to platelet glycoproteins. Some patients with chronic ITP are refractory to all therapies [steroids, intravenous immunoglobulin (IVIG), anti-D and immunosuppresive drugs] and have chronic low platelet counts and episodic bleeding. We retrospectively evaluated the efficacy and safety of rituximab treatment and splenectomy in paediatric patients diagnosed with chronic and refractory ITP who were unresponsive to steroids, IVIG, cyclosporine and mycophenolate mofetil. Records of patients with chronic and refractory ITP in 459 patients with primary ITP who were followed up in our hospital from January 2005 to December 2014 were reviewed. Fifteen of patients received rituximab and/or applied splenectomy. Fifteen chronic ITP patients (10 boys, five girls) with a mean age of 10 years were enrolled in the study. Two of these patients were suffering from Evans syndrome. The median time since diagnosis of ITP was 10 years. The median follow-up duration after starting Rituximab and splenectomy were 13 and 9.5 months, respectively.None of the seven patients who were treated with rituximab achieved a response. A splenectomy was performed in six of the seven patients who had been treated with rituximab. Complete and partial responses were achieved in 67 and 33% of the patients, respectively. We evaluated the clinical characteristics and responses of chronic ITP patients who did not receive rituximab therapy and underwent a splenectomy. The success rate was 100% in the eight patients with chronic and refractory ITP. Rituximab therapy might not be beneficial for some children with severe chronic ITP who are refractory to standard agents. A splenectomy might be useful and preferable to rituximab.

In the Eastern Province of Saudi Arabia, an area known for varioushemoglobinopathies, splenectomy is performed rather frequently. This study isan analysis of our experience with splenectomy performed for varioushematological disorders between 1988 and 1997, outlining the indications,complications and outcome. This is a retrospective analysis of all patientswho had splenectomy at our hospital during this period. One hundred andforty-three patients were treated for various hematological disorders at ourhospital. These disorders included sickle cell disease (SCD) (100 patients),sickle thalassemia (S-B-thalassemia) (13 ITP) (5 patients), Gaucher's disease(2 patients), hereditary spherocytosis (1 patient), autoimmune hemolyticanemia (1 patient), thalssemia intermediate (2 patients) and chronic myeloidleukemia (1 patient). The indications for splenectomy in those with SCD andthalassemia were: hypersplenism (26 patients), major splenic sequestrationcrisis (50 patients), splenic abscess (12 patients), and massive splenicinfarction (2 patients). Splenectomy in these patients was beneficial inreducing their transfusion requirements and its attendant risks, eliminatingthe discomfort from mechanical pressure of the enlarged spleen, avoiding therisks of acute splenic sequestration crisis, and managing splenic abscess.For those with Thalassemia, total splenectomy was beneficial in reducingtheir transfusion requirements, while partial splenectomy was beneficial onlyas a temporary measure, as regrowth of splenic remnant in these patientssubsequently led to increase in their transfusion requirements. Those withITP, hereditary spherocytosis, and autoimmune hemolytic anemia showedexcellent response following splenectomy. There was no mortality, and thepostoperative morbidity was 5.6%. With careful perioperative management,splenectomy is both safe and beneficial in a selected group of patients withhematological diseases. (author)

Immune responses to brain antigens after stroke contribute to poor outcome. We hypothesized that splenectomy would lessen the development of such responses and improve outcome. Male Lewis rats (275-350 g) underwent 2-hour middle cerebral artery occlusion immediately after splenectomy or sham splenectomy. Animals were survived to 4 weeks (672 hrs), and immune responses to myelin basic protein determined at euthanasia. Infarct volume was determined in a subset of animals euthanized at 72 hours. Behavioral outcomes were assessed to 672 hours. Splenectomy was associated with worse neurological scores early after stroke, but infarct size at 72 hours was similar in both groups. Behavioral outcomes and immune responses to myelin basic protein were also similar among splenectomized and sham-operated animals 672 hours after middle cerebral artery occlusion. Splenectomy did not alter the immune responses to brain antigens or improve outcome after stroke. Differences between this study and other studies of splenectomy and stroke are examined. © 2017 American Heart Association, Inc.

Abstract Background: Simultaneous splenectomy during liver transplantation (LT) is debated. The present meta-analysis assessed the efficacy and safety of splenectomy on the outcome of LT patients. Methods: We searched PubMed, Embase, and Wanfang databases for relevant studies published until the date of July 15, 2017. Quality assessment of the included studies was performed using a modified Newcastle-Ottawa Scale judgment. The data were analyzed using RevMan5.3 software. Results: A total of 16 studies consisting of 2198 patients (892 patients received splenectomy during LT [SPLT group] and 1306 patients received LT only [LT group]) were included in the present meta-analysis. Efficacy analysis revealed that pooled hazard ratio for overall survival (OS) between 2 groups was not significantly different (hazard ratio = 1.03; 95% confidence interval [CI]: 0.71–1.50). SPLT group had less postoperative rejection (odds ratio [OR] = 0.63, 95% CI: 0.50–0.79) and small for size syndrome (OR = 0.23, 95% CI: 0.07–0.79). SPLT group had significantly lower preoperative platelet (mean difference [MD] = −17.23, 95% CI: −19.54, −14.91), but significantly higher postoperative platelet (MD = 170.45, 95% CI: 108.33–232.56). Conversely, SPLT group had significant higher preoperative portal pressure (MD = 1.54, 95% CI: 0.75–2.33) and significant lower postoperative portal pressure (MD = −1.17, 95% CI: −2.24, −0.11). Safety analysis revealed that SPLT group had significantly longer operation time (MD = 56.66, 95% CI: 35.96–77.35), more intraoperative blood loss (MD = 1.08, 95% CI: 0.25–1.91), and more intraoperative red blood cell (RBC) transfusion (MD = 3.77, 95% CI: 3.22–4.33). Furthermore, SPLT group had significantly higher incidence of postoperative hemorrhage (OR = 3.07, 95% CI: 1.92–4.91), postoperative thrombosis (OR = 3.63, 95% CI: 1.06–12.45), and perioperative infection (OR = 2.62, 95% CI: 1.76�

Laparoscopic splenectomy (LS) has become an established standard of care in the management of surgical diseases of the spleen. The present article is an update and review of current procedures and controversies regarding minimally invasive splenectomy. We review the indications and contraindications for LS as well as preoperative considerations. An individual assessment of the procedures and outcomes of multiport laparoscopic splenectomy, hand-assisted laparoscopic splenectomy, robotic splenectomy, natural orifice transluminal endoscopic splenectomy and single-port splenectomy is included. Furthermore, this review examines postoperative considerations after LS, including the postoperative course of uncomplicated patients, postoperative portal vein thrombosis, infections and malignancy.

Full Text Available A 59-year-old female with a history of multiple splanchnic and portal thromboses treated with warfarin underwent an esophagogastroduodenoscopy for cancer screening, and a polypoid mass was biopsied. One week later, she was admitted with upper gastrointestinal hemorrhage. Her therapeutic coagulopathy was reversed with fresh frozen plasma, and she was transfused with packed red blood cells. An esophagogastroduodenoscopy demonstrated an erosion of a gastric varix without evidence of recent bleeding. Conservative measures failed, and she continued to bleed during her stay. She was not considered a candidate for a shunt procedure; therefore, a splenectomy was performed. Postoperative esophagogastroduodenoscopy demonstrated near complete resolution of gastric varices. One year after discharge on warfarin, there has been no recurrence of hemorrhage. Gastric varices often arise from either portal hypertension or splenic vein thrombosis. Treatment of gastric variceal hemorrhage can be challenging. Transjugular intrahepatic portosystemic shunt is often effective for emergency control in varices secondary to portal hypertension. Splenectomy is the treatment for varices that arise from splenic vein thrombosis. However, treatment of gastric variceal hemorrhage in the context of multiple splanchnic and portal vein thromboses is more complicated. We report splenectomy as a successful treatment of gastric varices in a patient with multiple extrahepatic thromboses.

Background Clinical outcomes of children with sickle cell disease (SCD) who undergo total or partial splenectomy are poorly defined. The purpose of this retrospective study was to initiate an internet-based registry to facilitate analysis of clinical outcomes for these children. We hypothesized that both surgical procedures would be well tolerated and would eliminate risk of splenic sequestration. Methods We developed a web-based registry using the Research Electronic Data Capture (REDCap) platform. Children were included if they had SCD and underwent total splenectomy (TS) or partial splenectomy (PS) between 2003 to 2010. Clinical outcomes were compared between cohorts, with follow-up to one year. Results Twenty-four children were included, total splenectomy (n=15) and partial splenectomy (n=9). There were no differences in surgical time or intraoperative blood loss. The length of stay was longer after PS (4.1±1.7 days) compared to TS, (2.4±1.2 days, p=0.02). Within 30 days of surgery, 2 (20%) patients had acute chest syndrome following TS and 2 (15%) patients had acute chest syndrome after PS. During one year follow-up, no patient in either cohort had recurrent splenic sequestration, venous thrombosis or overwhelming post-splenectomy sepsis. All children who were transfused preoperatively to prevent recurrent splenic sequestration successfully discontinued transfusions. Conclusions Both TS and PS result in favorable hematologic outcomes and low risk of adverse events for children with SCD. A REDCap based registry may facilitate data entry and analysis of clinical outcomes to allow for comparison between different types of splenectomy. PMID:22238140

Splenectomy is the only potentially curative treatment for chronic immune thrombocytopenic purpura (ITP) in adults. However, one-third of the patients relapse without predictive factors identified. We evaluate the predictive value of the site of platelet sequestration on the response to splenectomy in patients with ITP. Eighty-two consecutive patients with ITP treated by splenectomy between 1992 and 2013 were retrospectively reviewed. Platelet sequestration site was studied by (111)Indium-oxinate-labeled platelets in 93% of patients. Response to splenectomy was defined at last follow-up as: complete response (CR) for platelet count (PC) ≥100 × 10(9)/L, response (R) for PC≥30 × 10(9)/L and splenectomy was performed in 81 patients (conversion rate of 16%), and open approach in one patient. Median follow-up was 57 months (range, 1-235). Platelet sequestration study was performed in 93% of patients: 50 patients (61%) exhibited splenic sequestration, 9 (11%) hepatic sequestration and 14 patients (17%) mixed sequestration. CR was obtained in 72% of patients, R in 25% and NR in 4% (two with splenic sequestration, one with hepatic sequestration). Preoperative PC, age at diagnosis, hepatic sequestration and male gender were significant for predicting CR in univariate analysis, but only age (HR = 1.025 by one-year increase, 95% CI [1.004-1.047], p = 0.020) and pre-operative PC (HR = 0.112 for > 100 versus splenectomy was independent of the site of platelet sequestration in patients with ITP. Pre-operative platelet sequestration study in these patients cannot be recommended.

Randomized clinical trial of ligasure™ versus conventional splenectomy for injured spleen in blunt abdominal trauma.

Spleen is the most common organ damaged in cases of blunt abdominal trauma and splenectomy and splenorrhaphy are the main surgical procedures that are used in surgical treatment of such cases. In routine open splenectomy cases, after laparotomy, application of sutures in splenic vasculature is the most widely used procedure to cease the bleeding. This clinical trial evaluates the role and benefits of the Ligasure™ system in traumatic splenectomy without using any suture materials and compares the result with conventional method of splenectomy. After making decision for splenectomy secondary to a blunt abdominal trauma, patients in control group (39) underwent splenectomy using conventional method with silk suture ligation of splenic vasculature. In the interventional group (41) a Ligasure™ vascular sealing system was used for ligating of the splenic vein and artery. The results of operation time, volume of intra-operation bleeding and post-operative complications were compared in both groups. The mean operation times in control and interventional group were 21 and 12 min respectively (p trauma for splenectomy not only can decrease the operation time but also can decrease the volume of bleeding during operation without any additional increase in post-operative complications. This method is recommendable in traumatic splenic injuries that require splenectomy in order to control the bleeding as opposed to use of traditional silk sutures.

Because many physicians seem reluctant to recommend splenectomy for elderly patients with immune thrombocytopenia (ITP), we investigated the safety and efficacy of splenectomy and the predictive factors for response in these patients. 184 patients with primary ITP were retrospectively analyzed based on age at splenectomy: an elderly group (≥60 years, n = 52) and a younger group (splenectomy (HR 2.9, 95% CI: 1.24-6.80, p = 0.014) and platelet count on postoperative day 14 ≥200 × 109/l (HR 31.43, 95% CI: 4.15-238.28, p = 0.001) were independent factors for a favorable response. Age ≥60 years did not influence the response to splenectomy but was associated with increased relapse and postoperative complications. Splenectomy could provide a durable long-term response for elderly ITP patients. © 2016 S. Karger AG, Basel.

Simultaneous splenectomy during liver transplantation (LT) is debated. The present meta-analysis assessed the efficacy and safety of splenectomy on the outcome of LT patients. We searched PubMed, Embase, and Wanfang databases for relevant studies published until the date of July 15, 2017. Quality assessment of the included studies was performed using a modified Newcastle-Ottawa Scale judgment. The data were analyzed using RevMan5.3 software. A total of 16 studies consisting of 2198 patients (892 patients received splenectomy during LT [SPLT group] and 1306 patients received LT only [LT group]) were included in the present meta-analysis. Efficacy analysis revealed that pooled hazard ratio for overall survival (OS) between 2 groups was not significantly different (hazard ratio = 1.03; 95% confidence interval [CI]: 0.71-1.50). SPLT group had less postoperative rejection (odds ratio [OR] = 0.63, 95% CI: 0.50-0.79) and small for size syndrome (OR = 0.23, 95% CI: 0.07-0.79). SPLT group had significantly lower preoperative platelet (mean difference [MD] = -17.23, 95% CI: -19.54, -14.91), but significantly higher postoperative platelet (MD = 170.45, 95% CI: 108.33-232.56). Conversely, SPLT group had significant higher preoperative portal pressure (MD = 1.54, 95% CI: 0.75-2.33) and significant lower postoperative portal pressure (MD = -1.17, 95% CI: -2.24, -0.11). Safety analysis revealed that SPLT group had significantly longer operation time (MD = 56.66, 95% CI: 35.96-77.35), more intraoperative blood loss (MD = 1.08, 95% CI: 0.25-1.91), and more intraoperative red blood cell (RBC) transfusion (MD = 3.77, 95% CI: 3.22-4.33). Furthermore, SPLT group had significantly higher incidence of postoperative hemorrhage (OR = 3.07, 95% CI: 1.92-4.91), postoperative thrombosis (OR = 3.63, 95% CI: 1.06-12.45), and perioperative infection (OR = 2.62, 95% CI: 1.76-3.90). In addition, perioperative mortality was significantly higher in

Previous studies suggest that long-term mortality is increased in patients who undergo splenectomy during surgery for colorectal cancer. The reason for this association remains unclear. The purpose of this study was to investigate the association between inadvertent splenectomy attributed to iatrogenic lesion to the spleen during colorectal cancer resections and long-term mortality in a national cohort of unselected patients. This was a retrospective, nationwide cohort study. Data were collected from the database of the Danish Colorectal Cancer Group and merged with data from the National Patient Registry and the National Pathology Databank. Danish patients with colorectal cancer undergoing curatively intended resection between 2001 and 2011 were included in the study. The primary outcome was long-term mortality for patients surviving 30 days after surgery. Secondary outcomes were 30-day mortality and risk factors for inadvertent splenectomy. Multivariable and propensity-score matched Cox regression analyses were used to adjust for potential confounding. In total, 23,727 patients were included, of which 277 (1.2%) underwent inadvertent splenectomy. There was no association between inadvertent splenectomy and long-term mortality (adjusted HR = 1.15 (95% CI, 0.95-1.40); p = 0.16) in the propensity score-matched model, whereas 30-day mortality was significantly increased (adjusted HR = 2.31 (95% CI, 1.71-3.11); p splenectomy was most often seen during left hemicolectomy (left hemicolectomy vs right hemicolectomy: OR = 24.76 (95% CI, 15.30-40.06); p splenectomy during resection for colorectal cancer does not seem to increase long-term mortality. The previously reported reduced overall survival after inadvertent splenectomy may be explained by excess mortality in the immediate postoperative period.

The purpose of this prospective study is to evaluate the efficiency of perioperative spleen embolization prior to laparoscopic splenectomy indicated for hypersplenism. We conducted a prospective study exploring a technique combining ultra-selective perioperative embolization and splenectomy. Between January 2008 and March 2013, 16 splenectomies were performed in children suffering from hypersplenism due to varying hematologic diseases. Spleen embolization was performed by an interventional radiologist in the operating room (OR) just before splenectomy and during the same general anesthesia. Ages varied from 3 to 17 years. Spleen volume was measured by preoperative ultrasound. One patient underwent a laparotomy because of suspected adhesions due to previous surgery. All other operations were performed laparoscopically. One complication arose from embolization: a perforation of the splenic artery. After immediately placing a platinum coil proximal to the perforation, the splenectomy was carried out as usual. Fourteen children (87.5 %) had splenomegaly, of which eight (50 %) had massive splenomegaly. There were no deaths, no conversions to laparotomy, no reoperations and none of these patients had to be transfused. Perioperative spleen embolization performed in the OR by an interventional radiologist makes laparoscopic splenectomy a safer procedure. We propose a preoperative method for spleen measurement that is adapted to children: simple and massive splenomegaly is defined through patient body weight and a preoperative ultrasound. We conclude that spleen size is no more a limiting factor for laparoscopic splenectomy in children.

Hereditary spherocytosis (HS) is a heterogeneous hemolytic anemia treated with splenectomy in patients suffering from severe or moderate disease. Total splenectomy, however, renders patients vulnerable to overwhelming postsplenectomy infection despite preventive measures. Although subtotal splenectomy has been advocated as an alternative to total splenectomy, long-term follow-up data are scarce. We investigated how often hematologic recurrences requiring secondary total splenectomy occurred. With a follow-up of at least 5 years, we analyzed the data of 12 patients, aged 11 years maximum (median 6.5 years), who had undergone intended subtotal splenectomy, and 9 patients (median age 11.9 years), who had undergone total splenectomy. We compared their hematologic results and searched for factors associated with secondary spleen surgery. Hemolysis was reduced after subtotal splenectomy and absent after total splenectomy. Subtotal splenectomy was not successful in three children because no functional splenic remnant remained after 6 months (one conversion at surgery; one necrosis of splenic remnant; one early secondary splenectomy). Four children required secondary splenectomy after a median of 5 years for hematologic recurrence. In the remaining five patients, a functional splenic remnant was present for at least 5.5 years. The median time to secondary total splenectomy after intended subtotal splenectomy was 5.2 years. In all patients requiring secondary total splenectomy, increased reticulocyte levels within 2 years indicated hematologic recurrence. Subtotal splenectomy can be an alternative for total splenectomy in young patients with HS. It allows for hematologic improvement and may preserve splenic immune function for as many as 5 years. © 2017 Wiley Periodicals, Inc.

The association of acute nonlymphocytic leukemia with Hodgkin disease has been recorded in more than 100 instances. In most of these cases the patient has had long-standing Hodgkin disease and radiotherapy has been carried out. The combination of previous radiotherapy and chemotherapy appears to further increase the risk of leukemia developing. In a patient under our care with Hodgkin disease acute myelomonocytic leukemia developed following splenectomy for hypersplenism. The onset of acute leukemia immediately following splenectomy in a patient with Hodgkin disease has not previously been noted. In addition, because the patient's usual bone marrow sampling sites were hypoplastic, we utilized an 111 In-chloride bone marrow scan to find a site that was accessible for aspiration

Splenomegaly and pancytopenia are common in Wilson's disease (WD) and splenectomy is one of the conventional treatments for splenomegaly and the associated pancytopenia. However, splenectomy remained controversial for hypersplenism in WD as it was reported that splenectomy leaded to serious emotional and neurological deterioration in WD patients with hypersplenism. In the current study, we present our experiences in 70 WD patients with hypersplenism who had undergone splenectomy, outlining the safety and efficacy of splenectomy in WD. The clinical database of 70 WD patients with hypersplenism who had undergone splenectomy in our hospital between 2009 and 2013 were reviewed and followed-up regularly. Before splenectomy, all the patients accepted a short period of anti-copper treatment with intravenous sodium 2, 3-dimercapto-1-propane sulfonate (DMPS). All the patients demonstrated a marked improvement in platelet and leucocyte counts after splenectomy. No severe postoperative complication was observed. In particular, none of the 37 patients with mixed neurologic and hepatic presentations experienced neurological deterioration after splenectomy, and none of the patients with only hepatic presentations newly developed neurological symptoms. During the one year follow-up period, no patient presented hepatic failure or hepatic encephalopathy, no hepatic patient newly developed neurological presentations, and only 3 patients with mixed neurologic and hepatic presentations suffered neurological deterioration and these 3 patients had poor compliance of anti-copper treatment. Quantative analysis of the neurological symptoms in the 37 patients using the Unified Wilson's Disease Rating Scale (UWDRS) showed that the neurological symptoms were not changed in a short-term of one week after splenectomy but significantly improved in a long-term of one year after splenectomy. Additionally, compared to that before splenectomy, the esophageal gastric varices in most patients

Sickle cell anemia (SCA), which is characterized by high hemoglobin (Hb) F level and persistent splenomegaly into the older age group (up to 18 years of age) or even adults, is one of the commonest hemoglobinopathies in the Eastern Province of Saudi Arabia. This makes them liable to develop splenic complications requiring splenectomy. This is a review of our experience in the management of 134 children with SCA who had splenectomy as part of their management at our hospital, with emphasis given to the indications and complications of splenectomy. The medical records of all children who had splenectomy at our hospital were retrospectively reviewed for the following: age at splenectomy, sex, Hb electrophoresis, indication for splenectomy, preoperative investigations, type of surgery, spleen weight, histology, perioperative management, and postoperative complications. From 1990 to 2004, 170 children with various hematologic disorders had splenectomy at our hospital. Of these, 134 had SCA (118 had sickle cell disease and 16 had sickle-beta-thalassemia). Recurrent acute splenic sequestration crisis (ASSC) was the commonest indication for splenectomy in 103 (76.9%) patients, followed by hypersplenism in 18 (13.4%). Seven (5.2%) of our patients had splenectomy for splenic abscess (SA) and 2 had splenectomy for massive splenic infarction; 103 (61 boys, 42 girls) patients with a mean age of 7.6 years (range, 1.8-13 years) had splenectomy for ASSC. Their mean Hb F level was 20.5% (range, 9.2%-39.6%). Thirty-two of them had major attacks. Their Hb levels at the time of admission ranged from 1.4 to 4.1 g/dL (mean, 2.5 g/dL). The remaining 71 had minor recurrent attacks. Eighteen had splenectomy for hypersplenism and all had a significant increase in their blood parameters after splenectomy. Seven had splenectomy for SA. In 5 patients, Salmonella was the causative organism; in 1, it was Enterobacter sakazaki, whereas in 1, no organisms were identified. Two of our patients had

To evaluate the frequency of infectious complications in children with sickle cell disease (SCD) after surgical splenectomy for acute splenic sequestration crisis. Retrospective cohort of children with SCD who were born after 2002 and were regularly monitored until July 2013. Patients were divided into two groups: cases (children with SCD who underwent surgical splenectomy after an episode of splenic sequestration) and controls (children with SCD who did not have splenic sequestration and surgical procedures), in order to compare the frequency of invasive infections (sepsis, meningitis, bacteremia with positive blood cultures, acute chest syndrome and/or pneumonia) by data collected from medical records. Data were analyzed by descriptive statistical analysis. 44 patients were included in the case group. The mean age at the time of splenectomy was 2.6 years (1-6.9 years) and the mean postoperative length of follow-up was 6.1 years (3.8-9.9 years). The control group consisted of 69 patients with a mean age at the initial follow-up visit of 5.6 months (1-49 months) and a mean length of follow-up of 7.2 years (4-10.3 years). All children received pneumococcal conjugate vaccine. No significant difference was observed between groups in relation to infections during the follow-up. Surgical splenectomy in children with sickle cell disease that had splenic sequestration did not affect the frequency of infectious complications during 6 years of clinical follow-up.

Splenectomy is associated with a life-long risk for overwhelming infections. The risk for early post-operative infectious complications following traumatic and elective splenectomy is, however, understudied. This investigation aimed to determine if splenectomy increases the risk for post-operative infections. This was a retrospective review of prospectively collected data on patients admitted to the surgical intensive care unit (SICU) between 1/2011 and 7/2013 investigating the risk for infectious complications in patients undergoing a splenectomy compared with those undergoing any other abdominal surgery. During the 30-month study period, a total of 1884 patients were admitted to the SICU. Of those, 33 (2%) had a splenectomy and 493 (26%) had an abdominal surgery. The two groups were well balanced for age, APACHE IV score >20, and past medical history, including diabetes mellitus, cardiac history, renal failure or immunosuppression. Patients undergoing splenectomy were more likely to have sustained a traumatic injury (30% vs. 7%, p splenectomy was associated with increased risk for infectious complications (49% vs. 29%, Adjusted Odds Ratio (AOR) [95% CI]: 2.7 [1.3, 5.6], p = 0.01), including intra-abdominal abscess (9% vs. 3%, AOR [95% CI]: 4.3 [1.1, 16.2], p = 0.03). On a subgroup analysis, there were no differences between traumatic and elective splenectomy with regards to overall infectious complications (50% vs. 46%, p = 0.84), although, abdominal abscess developed only in those who had an elective splenectomy (0% vs. 12%, p = 0.55). Splenectomy increases the risk for post-operative infectious complications. Further studies identifying strategies to decrease the associated morbidity are necessary.

Splenectomy has been suggested to have an impact on immunological function, and subsequent development of cancer has been recognized as a possible adverse effect of splenectomy. This study evaluated the possible association between splenectomy and malignancy in Taiwan. A cohort study consisted of including 2,603 patients with nontraumatic and 2,295 patients with traumatic splenectomy, and then randomly frequency matched with 4 participants without splenectomy. The Cox proportional hazard regression analysis was conducted to estimate the influence of splenectomy on cancer risk. Both nontraumatic and traumatic splenectomy had a significantly higher risk for overall cancer development (adjusted hazard ratios are 2.64 and 1.29 for nontraumatic and traumatic reasons, respectively). After adjusting for age, sex, and comorbidities, patients with splenectomy were associated with significantly higher risks for developing certain gastrointestinal tract cancers, other head and neck cancers, and hematological malignancies, and the phenomenon is more prominent in nontraumatic splenectomy group. This nationwide population-based study found that people with splenectomy have higher risks of developing overall cancer, as well as certain site-specific cancers, especially for patients with nontraumatic reasons.

Splenectomy, while often necessary in otherwise healthy patients after major trauma, finds its primary indication for patients with underlying malignant or nonmalignant hematologic diseases. Indications of splenectomy for hematologic diseases have been reducing in the last few years, due to improved diagnostic and therapeutic tools. In high-income countries, there is a clear decrease over calendar time in the incidence of all indication splenectomy except nonmalignant hematologic diseases. However, splenectomy, even if with different modalities including laparoscopic splenectomy and partial splenectomy, continue to be a current surgical practice both in nonmalignant hematologic diseases, such as Immune Thrombocytopenic Purpura (ITP), Autoimmune Hemolytic Anemia (AIHA), Congenital Hemolytic Anemia such as Spherocytosis, Sickle Cell Anemia and Thalassemia and Malignant Hematological Disease, such as lymphoma. Today millions of people in the world are splenectomized. Splenectomy, independently of its cause, induces an early and late increase in the incidence of venous thromboembolism and infections. Infections remain the most dangerous complication of splenectomy. After splenectomy, the levels of antibody are preserved but there is a loss of memory B cells against pneumococcus and tetanus, and the loss of marginal zone monocytes deputed to immunological defense from capsulated bacteria. Commonly, the infections strictly correlated to the absence of the spleen or a decreased or absent splenic function are due to encapsulated bacteria that are the most virulent pathogens in this set of patients. Vaccination with polysaccharide and conjugate vaccines again Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis should be performed before the splenectomy. This practice reduces but does not eliminate the occurrence of overwhelming infections due to capsulated bacteria. At present, most of infections found in splenectomized patients are due to Gram

Patients with acute kidney injury (AKI) have increased serum proinflammatory cytokines and an increased occurrence of respiratory complications. The aim of the present study was to examine the effect of renal and extrarenal cytokine production on AKI-mediated lung injury in mice. C57Bl/6 mice underwent sham surgery, splenectomy, ischemic AKI, or ischemic AKI with splenectomy and kidney, spleen, and liver cytokine mRNA, serum cytokines, and lung injury were examined. The proinflammatory cytokines IL-6, CXCL1, IL-1β, and TNF-α were increased in the kidney, spleen, and liver within 6 h of ischemic AKI. Since splenic proinflammatory cytokines were increased, we hypothesized that splenectomy would protect against AKI-mediated lung injury. On the contrary, splenectomy with AKI resulted in increased serum IL-6 and worse lung injury as judged by increased lung capillary leak, higher lung myeloperoxidase activity, and higher lung CXCL1 vs. AKI alone. Splenectomy itself was not associated with increased serum IL-6 or lung injury vs. sham. To investigate the mechanism of the increased proinflammatory response, splenic production of the anti-inflammatory cytokine IL-10 was determined and was markedly upregulated. To confirm that splenic IL-10 downregulates the proinflammatory response of AKI, IL-10 was administered to splenectomized mice with AKI, which reduced serum IL-6 and improved lung injury. Our data demonstrate that AKI in the absence of a counter anti-inflammatory response by splenic IL-10 production results in an exuberant proinflammatory response and lung injury. PMID:21677145

The aim of our study is to evaluate the risk of morbidity and mortality of splenectomy in pregnant women compared with non-pregnant women. We conducted a retrospective population-based matched cohort study using the Health Care Cost and Utilization Project, Nationwide Inpatient Sample database from 2003 to 2011. Pregnant women with splenectomy were age-matched to non-pregnant women with splenectomy. We compared risks of morbidity and mortality between pregnant and non-pregnant women using conditional logistic regression analysis. The non-pregnant group had an excess of white patients and a greater proportion of Medicaid and private insurance users. There was a tendency for greater frequency of laparotomies in pregnant patients. Risk of VTE, portal vein thrombosis, renal failure and sepsis were comparable between the groups. Risk for transfusion was higher amongst pregnant women (OR 2.2, 95% CI (1.7-2.8)), as was the risk for a longer hospital stay (OR 1.7, 95% CI (1.4-2.1)). Caution should be taken when performing splenectomy during pregnancy as risk for complications and mortality may be increased. Additional measures should be undertaken to have blood units on reserve for this population.

The impact of splenectomy on human coronary artery atherosclerosis and vascular macrophage distribution.

Science.gov (United States)

Li, Yu; Stone, James R

Splenectomy can potentially impact atherosclerosis through multiple mechanisms including altered lipid homeostasis, increased coagulation, and altered macrophage recruitment to the plaque. In patients, splenectomy has been associated with increased rates of coronary artery events, while in experimental mice, splenectomy causes increased atherosclerosis but reduces systemic monocyte supply. In this study, the direct impact of splenectomy on human coronary artery atherosclerotic plaque severity and macrophage content was investigated. Coronary artery atherosclerotic plaque severity was determined at autopsy in 18 long-term (≥10 years) splenectomy patients and 90 matched control patients. Coronary artery macrophage content was evaluated in mild atherosclerotic plaques of 11 mid- to long-term (≥1 year) splenectomy patients and 11 matched control patients. Splenectomy was associated with reduced coronary artery atherosclerosis (P=.03). The association was most pronounced for the subgroup of patients who had undergone splenectomy 20 years or more prior to death (P=.02). There was no difference in the density of macrophages in the plaque, media, or adventitia upon comparing splenectomy and control patients. In the control group, there was no correlation between the macrophage densities in the three arterial layers. However, in the splenectomy patients, there was a strong correlation in the macrophage densities across the plaque, media, and adventitia (P≤.0002), with resulting slopes that were significantly greater than seen in the control patients (P=.0007-.011). These findings indicate that, in humans, splenectomy is associated with lower coronary artery atherosclerotic plaque severity and altered coronary artery macrophage distribution. These results suggest that the spleen can modulate the recruitment of macrophages into human coronary arteries and the progression of atherosclerosis. Copyright © 2016 Elsevier Inc.

The purpose of this study was to evaluate the impact of splenectomy in adult-to-adult living donor liver transplantation (LDLT). Adult-to-adult LDLTs (n = 276) were divided into those with simultaneous splenectomy during LDLT (Splenectomy group, n = 154) and those without (Non-Splenectomy group, n = 122). In the Splenectomy group, splenectomy decreased the portal venous pressure from 24.0 to 19.1 mmHg (p Splenectomy group compared with the Non-Splenectomy group. The graft portal venous flow was also better in the Splenectomy group (y = 625-5.1x; r (2) = 0.08, p Splenectomy group (y = 470-2.9x; r (2) = 0.04, p = 0.03). Fourteen days after LDLT, the total bilirubin and ascites output were lower in the Splenectomy group than in the Non-Splenectomy group. Among the patients with hepatitis C, splenectomy was associated with a significantly higher rate of a sustained viral response (59.4 vs. 35.9%, p = 0.020) than was noted in those without splenectomy (n = 39). There were no patients with post-splenectomy sepsis under vaccination. By decreasing the portal pressure and increasing the graft vascular compliance, splenectomy conferred better graft outcomes in adult-to-adult LDLT.

History, signalment, results of physical examination, results of preoperative diagnostic testing, details of surgical technique, intraoperative findings including results of abdominal exploration and staging, concurrent surgical procedures, complications, histopathologic diagnoses, duration of postoperative hospitalization, and perioperative outcome were recorded. The perioperative period was defined as the time from hospital admission for LAS until discharge or death (within the same visit). All dogs underwent initial abdominal exploration and staging via multiple 5-mm laparoscopic ports (n = 2) or a single commercially available multichannel port (16), followed by minilaparotomy with insertion of a wound retraction device, progressive exteriorization of the spleen, sealing of hilar vessels, and splenectomy. Splenectomy was performed for treatment of a splenic mass (n = 15), suspected neoplasia (2), or refractory immune-mediated disease (1). Median size (width × length) of splenic masses was 5 × 5 cm (range, 1.6 to 11.0 cm × 1.5 to 14.5 cm). Complications were limited to minor intraoperative hemorrhage in 1 dog; no patient required conversion to open laparotomy. Results indicated that LAS was technically feasible in dogs and not associated with major complications. Further evaluation is required; however, in appropriately selected patients, LAS may offer the benefits of a minimally invasive technique, including a smaller incision and improved illumination and magnification during exploration and staging.

Distal pancreatectomy with splenectomy may be required for optimal cytoreductive surgery in patients with epithelial ovarian cancer (EOC) metastasized to splenic hilum. This study evaluates the morbidity and treatment outcomes of the uncommon procedure in the management of advanced or recurrent EOC. This study recruited 18 patients who underwent distal pancreatectomy with splenectomy during cytoreductive surgery of EOC. Their clinicopathological characteristics and follow-up data were retrospectively analyzed. All tumors were confirmed as high-grade serous carcinomas. The median diameter of metastatic tumors located in splenic hilum was 3.5 cm (range, 1 to 10 cm). Optimal cytoreduction was achieved in all patients. Eight patients (44.4%) suffered from postoperative complications. The morbidity associated with distal pancreatectomy and splenectomy included pancreatic leakage (22.2%), encapsulated effusion in the left upper quadrant (11.1%), intra-abdominal infection (11.1%), pleural effusion with or without pulmonary atelectasis (11.1%), intestinal obstruction (5.6%), pneumonia (5.6%), postoperative hemorrhage (5.6%), and pancreatic pseudocyst (5.6%). There was no perioperative mortality. The majority of complications were treated successfully with conservative management. During the median follow-up duration of 25 months, nine patients experienced recurrence, and three patients died of the disease. The 2-year progression-free survival and overall survival were 40.2% and 84.8%, respectively. The inclusion of distal pancreatectomy with splenectomy as part of cytoreduction for the management of ovarian cancer was associated with high morbidity; however, the majority of complications could be managed with conservative therapy.

Hereditary hemolytic anemias are a group of disorders with a variety of causes, including red cell membrane defects, red blood cell enzyme disorders, congenital dyserythropoietic anemias, thalassemia syndromes and hemoglobinopathies. As damaged red blood cells passing through the red pulp of the spleen are removed by splenic macrophages, splenectomy is one possible therapeutic approach to the management of severely affected patients. However, except for hereditary spherocytosis for which the effectiveness of splenectomy has been well documented, the efficacy of splenectomy in other anemias within this group has yet to be determined and there are concerns regarding short- and long-term infectious and thrombotic complications. In light of the priorities identified by the European Hematology Association Roadmap we generated specific recommendations for each disorder, except thalassemia syndromes for which there are other, recent guidelines. Our recommendations are intended to enable clinicians to achieve better informed decisions on disease management by splenectomy, on the type of splenectomy and the possible consequences. As no randomized clinical trials, case control or cohort studies regarding splenectomy in these disorders were found in the literature, recommendations for each disease were based on expert opinion and were subsequently critically revised and modified by the Splenectomy in Rare Anemias Study Group, which includes hematologists caring for both adults and children.

Surgery for remnant gastric cancer (RGC) frequently fails to obtain the >15 lymph nodes necessary for tumor-node-metastasis (TNM) staging. We aimed to evaluate the utility of the recently developed tumor-ratio-metastasis (TRM) staging system. We also examined the pattern of lymph node metastasis and the role of prophylactic splenectomy in RGC. Between May 2003 and December 2012, data from 170 patients who underwent surgery for RGC were retrospectively analyzed. RGC arising after previous benign disease (n = 46) was associated with retrieval of more lymph nodes (27.3 vs 10.0; P splenectomy and non-splenectomy groups at each stage (P = 0.751, 0.723, 0.151, and 0.706 for stage I, II, III, and IV, respectively). The analyses did not identify a survival benefit from prophylactic splenectomy or show an improvement in staging with the TRM system for RGC. © 2017 Wiley Periodicals, Inc.

2006-01-01

Objective: To analyze the effects and the complications of partial splenic artery embolization (PSE) and splenectomy offering a feasible way to choose different therapeutic methods for hypersplenism. Methods: Forty-six patients treated with PSE and thirty-three undergone splenectomy were compared for their effectivenesses and complications in treating hypersplenism. Results: Thrombocyte and leucocyte counts increased markedly after the two kinds of treatment (P 0.05). The complication rate of the PSE was far more than that of the splenectomy (P<0.001). Conclusions Splenectomy is prior to PSE on patients with large mount of ascites, serious portal hypertension and splenomegaly. PSE is suitable for patients with poor liver function, blood coagulation disturbance, liver cancer complicated with hypersplenism and aging. (authors)

Full Text Available Abstract Objective Non-operative management of blunt splenic injury in adults has been applied increasingly at the end of the last century. Therefore, the lifelong risk of overwhelming post-splenectomy infection has been the major impetus for preservation of the spleen. However, the prevalence of posttraumatic infection after splenectomy in contrast to a conservative management is still unknown. Objective was to determine if splenectomy is an independent risk factor for the development of posttraumatic sepsis and multi-organ failure. Methods 13,433 patients from 113 hospitals were prospective collected from 1993 to 2005. Patients with an injury severity score > 16, no isolated head injury, primary admission to a trauma center and splenic injury were included. Data were allocated according to the operative management into 2 groups (splenectomy (I and conservative managed patients (II. Results From 1,630 patients with splenic injury 758 patients undergoing splenectomy compared with 872 non-splenectomized patients. 96 (18.3% of the patients with splenectomy and 102 (18.5% without splenectomy had apparent infection after operation. Additionally, there was no difference in mortality (24.8% versus 22.2% in both groups. After massive transfusion of red blood cells (> 10 non-splenectomy patients showed a significant increase of multi-organ failure (46% vs. 40% and sepsis (38% vs. 25%. Conclusions Non-operative management leads to lower systemic infection rates and mortality in adult patients with moderate blunt splenic injury (grade 1-3 and should therefore be advocated. Patients with grade 4 and 5 injury, patients with massive transfusion of red blood cells and unstable patients should be managed operatively.

MANAGEMENT OF CHRONIC IDIOPATHIC THROMBOTIC THROMBOCYTOPENIC PURPURA WITH SPLENECTOMY

Full Text Available Background. Treatment of thrombotic thrombocytopenic purpura (TTP with plasma exchange (PE has reduced mortality rates from 90% in untreated patients to less than 20%. Despite primary effective PE, relapses occur in up to 40% of patients. Beside PE, second line treatment options are corticosteroids, vincristine, defibrotide, prostacycline. We describe two patients with relapsing TTP treated successfully with splenectomy.Patients and methods. Case 1. A 20–year female was diagnosed in October 2000 with idiopathic chronic relapsing TTP. First episode of PE plus methylprednisolone treatment led to complet remission. Subsequent relapses occured 3, 6 and 8 months after first TTP episode. Every relaps was effectivelly treated with PE and methylprednisolone. Because of more and more frequent TTP relapses laparoscopic splenectomy was performed. Currently, 7 months after splenectomy she is in complet TTP remission.Case 2. A 18–year female, was diagnosed in January 1997 with idiopathic TTP. After PE and methylprednisolone complete remission was established. Relaps occured after nearly three years. Later on, TTP got chronic course with neurological clinical symptoms and plateled drops as soon as PE treatment was withdrawn. Besides PE and methylprednisolone she received also defibrotide. Because of chronic, PE dependant TTP, laparoscopic splenectomy was performed. Today, 15 months after splenectomy she is in complete TTP remission.Conclusions. In idiopathic relapsing and chronic TTP, PE treatment only is usually not sufficient for durable remission. Second line TTP treatment drugs have limited efficacy. Based on our experience in patients with relapsing and/or chronic TTP, laparoscopic splenectomy should be considered as a first treatment option, especialy in junger patients.

Laparoscopic splenectomy is a well described gold standard procedure for various indications. One of the key steps during laparoscopic splenectomy is the hilar pedicle vessels control, which can be challenging in most cases. Most centres around the world recommend the use Ligaclib or endovascular staplers as Methods of choice for hilar pedicle control but the issue is the cost and efficiency of the laparoscopic haemostatic devices. A descriptive retrospective study of patients who had laparoscopic splenectomy from 2013 to present. Hilar splenic vessel control was done with suture ligation. We looked at outcomes of patients offered this technique, complications of this technique, and describing the technique of hilar control in laparoscopic splenectomy. Total of 27 patients had laparoscopic splenectomy with splenic hilar pedicle control with suture ligation. Mean operative time, mean blood volume loss, length of hospital stay, postoperative complications conversion to laparotomy. Laparoscopic hilar pedicle control with suture ligation is safe and effective for the patient in our hospital setting.

Thrombocytosis following splenectomy is a common occurrence. Whether this thrombocytosis leads to a higher risk for venous thromboembolism (VTE) remains unclear. This investigation aimed to determine if splenectomy increases the risk for VTE. This was a prospective study conducted in the SICU between 1/2011 and 11/2013 investigating the VTE risk in patients undergoing a splenectomy compared with those undergoing any other abdominal procedure. In total 2503 patients were admitted to the SICU: 37 (2%) after a splenectomy and 638 (26%) after any other abdominal surgery. Splenectomy patients had a higher incidence of VTE compared to patients undergoing any other abdominal procedure (29.7% vs. 12.1%, p splenectomy was associated with a higher adjusted risk for VTE compared to the no-splenectomy group (AOR [95% CI]: 2.6 [1.2, 5.9], p = 0.02). Reactive thrombocytosis did not predict the development of VTE. Splenectomy increases the risk for VTE, however reactive thrombocytosis is not associated with this higher incidence. Further investigations are required to characterize the pathophysiologic mechanisms of VTE development following splenectomy. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

Partial Splenectomy in the treatment of an adult with β thalassemia intermedia: A case report.

Science.gov (United States)

Correia, João Guardado; Moreira, Nídia; Costa Almeida, Carlos Eduardo; Reis, Luís Simões

2017-01-01

Thalassemia is a common disease which treatment is often based on splenectomy. The risks associated with total splenectomy stimulated partial splenectomy as a potentially alternative therapy. A 45 year-old female patient with long term follow-up for β thalassemia intermedia started to develop signs of hypersplenism and iron overload. A partial splenectomy was performed and was observed a marked hematologic improvement while preserving the desired splenic function. Partial splenectomy proved to provide a persistent decrease in hemolytic rate while preserving the integrity of splenic phagocytic function, presenting itself as an effective alternative to total splenectomy. After being subjected to partial splenectomy, our patient experienced a sustained control of hemolysis and showed no signs of hypersplenism or iron overload. No splenic regrowth or infectious complications were observed. The major drawbacks of partial splenectomy are the increased risk of intra- and postoperative bleeding, splenic remnant torsion and splenic regrowth. Partial splenectomy is an alternative to total splenectomy for the treatment of adult β Thalassemia intermedia patients avoiding the risks associated with total splenectomy.

Until now 40 robotic splenectomies were performed in our department, the first case being done on February 25, 2008. Our data show that robotic splenectomy with the DaVinci surgical system is technically feasible and safe, with good results and without complications. The main advantages are a better tridimensional view and an increased versatility of the surgical instruments. The DaVinci system allows an accurate dissection around the splenic hilum and preservation of the splenic remnant vessels in partial splenectomy. Robotic splenectomy will probably not replace the laparoscopic splenectomy for the most common indications like ITP, hemolytic anemia. It may be a very useful surgical tool in difficult splenectomy: partial splenectomy, splenectomy in liver cirrhosis, splenic tumors or malignant hemopathies. In these cases the robotic approach may shorten the operative time, decrease the blood loss and the risk of remorrhagic complications during surgery and even make possible a minimally invasive splenectomy very difficult to be performed by classical laparoscopy.

Effect of splenectomy on liver cirrhosis and related surgical issues

2016-12-01

Full Text Available Patients with liver fibrosis and cirrhosis experience certain changes in spleen morphology and function, and there is always a controversy over whether to perform splenectomy in patients with liver cirrhosis. As a surgical treatment of recurrent portal hypertension complicated by esophagogastric variceal bleeding, splenectomy can reduce portal venous pressure, reduce the possibility of gastrointestinal bleeding, and correct the reduced white blood cell count and platelet count. It can also protect the liver by improving liver function, promoting regeneration of hepatocytes, and inhibiting the progression of liver fibrosis. With reference to available clinical and laboratory data, this article reviews the effect of splenectomy on the cirrhotic liver and related issues such as selection of surgical procedures and prevention and treatment of postoperative complications, in order to promote splenectomy in patients with liver cirrhosis.

In the last century, with the advancement of the diagnostic procedures, hematologic disorders in pediatric age group have been increased dramatically. In parallel with this increase, splenectomy procedures have also been popularized with different techniques and surgical outcomes. Laparoscopic splenectomy (LS) in the pediatric age group is generally accepted as a technically demanding procedure, which needs experience. The purpose of this study is to present the long-term follow-up results of a case series of children who underwent LS for a variety of hematologic disorders, evaluate possible complications and outcomes. All patients who were admitted to the clinic and who were scheduled for LS from 2005 to 2016 were considered for this study. The study parameters were grouped in four categories including socio-demographic data, preoperative evaluation, clinical follow-up and complications. There were 24 male (48.9%) and 25 (51.1%) female patients. The median age and body weight for the study group was 12 years and 35 kg. Most common indications for LS were thalassemia (13; 26.5%) and hereditary spherocytosis (12; 24.4%). As a technical standpoint, 2 patients (4%) underwent singleport LS surgery. The mean time for LS surgeries was found as 80 minutes. The total intraoperative complication rate was 4% (2/57). The mean time for hospital stay was 5 days. Mean follow-up period was 6.4 years (range: 6 months-16 years). There was no long-term complication. Bilirubin levels and need for blood transfusion significantly decreased in the long term follow-up period (p <0.05). LS is a powerful tool in the hands of an experienced surgeon. It's a safe and effective procedure in children with hematologic disorders resulting in shorter length of stay and lower complication rates. Sociedad Argentina de Pediatría

To determine the impact of survival of peritoneal versus splenic metastasis in cases submitted to splenectomy as part of cytoreductive surgery in recurrent epithelial ovarian cancer. Between January 2002 and May 2014, 28 patients were submitted to splenectomy as part of secondary, tertiary and beyond tertiary cytoreduction at the Dan Setlacec Center of Gastrointestinal Disease and Liver Transplantation, Fundeni Clinical Institute, Bucharest. Splenectomy was performed as follows: at secondary cytoreduction in 21 cases, at tertiary cytoreduction in six cases, and beyond tertiary cytoreduction in one case. An R0 resection was attempted in all cases; however, in two cases submitted to splenectomy as part of tertiary cytoreduction, R1 and R2 resection, were performed, respectively. Histopathological studies revealed the presence of peritoneal seeding in 11 cases at secondary cytoreduction and in four cases submitted to splenectomy as part of tertiary cytoreduction. Parenchymatous lesions were described in nine cases submitted to splenectomy as part of secondary cytoreduction and in two cases at tertiary cytoreduction. In a single case in which splenectomy was performed in the context of secondary cytoreduction, hilar involvement was found. Peritoneal seeding was described in the patient for whom splenectomy was performed at quaternary cytoreduction. Early postoperative mortality for the entire cohort (within 30 days) was 7.1% (death occurred in two cases submitted to splenectomy during the secondary cytoreduction). The median overall survival in patients with splenic involvement via peritoneal route was 35 months, while in cases with hematogenous splenic lesions, it was 12 months (p=0.2) at secondary cytoreduction. In the sub-group of patients submitted to splenectomy as part of tertiary cytoreduction, the median overall survival in patients with splenic involvement via peritoneal route was 21 months, while in cases with hematogenous splenic lesions it was 4 months (p=0

Background Splenectomy is a clinical risk factor for complicated thrombosis. We hypothesized that the loss of the mechanical filtering function of the spleen may enrich for thrombogenic phospholipids in the circulation, thereby affecting the vascular remodeling of thrombosis. Methods and Results We investigated the effects of splenectomy both in chronic thromboembolic pulmonary hypertension (CTEPH), a human model disease for thrombus nonresolution, and in a mouse model of stagnant flow venous thrombosis mimicking deep vein thrombosis. Surgically excised thrombi from rare cases of CTEPH patients who had undergone previous splenectomy were enriched for anionic phospholipids like phosphatidylserine. Similar to human thrombi, phosphatidylserine accumulated in thrombi after splenectomy in the mouse model. A postsplenectomy state was associated with larger and more persistent thrombi. Higher counts of procoagulant platelet microparticles and increased leukocyte–platelet aggregates were observed in mice after splenectomy. Histological inspection revealed a decreased number of thrombus vessels. Phosphatidylserine‐enriched phospholipids specifically inhibited endothelial proliferation and sprouting. Conclusions After splenectomy, an increase in circulating microparticles and negatively charged phospholipids is enhanced by experimental thrombus induction. The initial increase in thrombus volume after splenectomy is due to platelet activation, and the subsequent delay of thrombus resolution is due to inhibition of thrombus angiogenesis. The data illustrate a potential mechanism of disease in CTEPH. PMID:24584745

The management of splenic injuries has shifted from splenectomy to splenic preservation owing to the risk of overwhelming post-splenectomy infection (OPSI). This study aimed to identify the factors that determine splenectomy in patients with isolated splenic injuries, with a view to increasing the rate of splenic preservation. Files of 55 patients managed for isolated splenic injuries from blunt abdominal trauma between 1998 and 2007 were retrospectively analysed using a pro forma. Management options were classified into nonoperative, operative salvage and splenectomy. The majority of patients suffered splenic injury as a result of motor vehicle accident (MVA) trauma or falls. Splenectomy was undertaken in 33 (60%) patients, 12 (22%) had non-operative management, and operative salvage was achieved in 10 (18%) patients. Significant determinants of splenectomy were grade of splenic injury, hierarchy of the surgeon, and hierarchy of the assistant. MVA injury and falls accounted for the vast majority of blunt abdominal trauma in this study. The rate and magnitude of energy transferred versus splenic protective mechanisms at the time of blunt abdominal trauma seems to determine the grade of splenic injury. Interest in splenic salvage surgery, availability of technology that enables splenic salvage surgery, and the experience of the surgeon and assistant appear to determine the surgical management. Legislation on vehicle safety and good parental control may reduce the severity of splenic injury in blunt abdominal trauma. When surgery is indicated, salvage surgery should be considered in intermediate isolated splenic injury to reduce the incidence of OPSI.

Since early 1990’s, when it was inaugurally introduced, laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications. Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen. However some contraindications still apply. The evolution of the technology has allowed though, cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches. Moreover, the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications. Today, laparoscopic splenectomy is considered safe, with better outcomes in comparison to open splenectomy, and the increased experience of surgeons allows operative times comparable to those of an open splenectomy. In this review we discuss the indications and the contraindications of laparoscopic splenectomy. Moreover we analyze the standard and modified surgical approaches, and we evaluate the short-term and long-term outcomes. PMID:28979707

Seeding of splenic tissue to extra-abdominal sites is a relatively infrequent consequence of open abdominal trauma. Immunological function of these small foci of ectopic splenic tissue is unknown and their use in determining the splenic function may be limited. In this case report, a patient is described who had previously undergone an emergency splenectomy. The absence of Howell-Jolly bodies on the blood smear in a patient who had previously undergone surgical splenectomy raised the suspicion of splenosis. The immunological features as well as non-invasive evaluation of these ill-defined splenic tissue sites are discussed.

To investigate the diagnostic performance of liver stiffness measurement (LSM) by elastography point quantification (ElastPQ) in animal models and determine the longitudinal changes in liver stiffness by ElastPQ after splenectomy at different stages of fibrosis. Liver stiffness was measured in sixty-eight rabbits with CCl 4 -induced liver fibrosis at different stages and eight healthy control rabbits by ElastPQ. Liver biopsies and blood samples were obtained at scheduled time points to assess liver function and degree of fibrosis. Thirty-one rabbits with complete data that underwent splenectomy at different stages of liver fibrosis were then included for dynamic monitoring of changes in liver stiffness by ElastPQ and liver function according to blood tests. LSM by ElastPQ was significantly correlated with histologic fibrosis stage ( r = 0.85, P fibrosis, moderate fibrosis, and cirrhosis, respectively. Longitudinal monitoring of the changes in liver stiffness by ElastPQ showed that early splenectomy (especially F1) may delay liver fibrosis progression. ElastPQ is an available, convenient, objective and non-invasive technique for assessing liver stiffness in rabbits with CCl 4 -induced liver fibrosis. In addition, liver stiffness measurements using ElastPQ can dynamically monitor the changes in liver stiffness in rabbit models, and in patients, after splenectomy.

A study was made of the bone marrow status in unirradiated zones on 33 patients with stage 1-2 Hodgkin's disease in complete 9-12 year remission after therapeutic irradiation of the lymphatic collectors of the upper part of the trunk in combination with irradiation of the system (16 patients) or splenectomy (17 patients). The total count of myelokaryocytes, myelogram, a relative and absolute content of lymphoid cells, immature granulocytes and elements of the erythroid series were defined in the punctates of the upper portion of the ilium. T- and B-lymphocyte count, the number of granulocytomacrophage (CFU-C) and stromal (CFU-F) precursor cells were defined using morphocytochemical and immunological methods. At that time an increase in the relative and absolute content of C- ad B-lymphocytes was noted. The T-cell count and the total number of myelokaryocytes, on the one hand, and the content of immature granulocytes and erythronormoblasts, on the other had, showed correlation of various degree which was particularly noticeable in the group of unoperated patients. The total number of myelokaryocytes in 1 μl of the bone marrow of the patients after splenectomy, on an average, significantly exceeded that in the group of patients with the irradiated spleen. These changes were considered to be a result of the rearragement of T-differentiating lymphocytes with their raised accumulation in the bone marrow after irradiation of a considerable volume of the lymphoid tissue and spleen or after splenectomy

Objective: Although the anterior approach is normally used for elective laparoscopic splenectomy (LS), the posterolateral approach may be superior. We have retrospectively compared the effectiveness and safety of these approaches in patients with non-severe splenomegaly scheduled for elective total LS. Methods: Patients with surgical spleen disorders scheduled for elective LS between March 2005 and June 2011 underwent laparoscopic splenic mobilization via the posterolateral or anterior approach. Main outcome measures included operation time, intraoperative blood loss, frequency of postoperative pancreatic leakage, and length of hospital stay. Results: During the study period, 203 patients underwent LS, 58 (28.6%) via the posterolateral and 145 (71.4%) via the anterior approach. Three patients (1.5%) required conversion to laparotomy due to extensive perisplenic adhesions. The posterolateral approach was associated with significantly shorter operation time (65.0 ± 12.3 min vs. 95.0 ± 21.3 min, P 0.05) Conclusions: The posterolateral approach is more effective and safer than the anterior approach in patients without severe splenomegaly (< 30 cm).

We studied the effects of a splenectomy in combination with immunotherapy on the survival of patients who had undergone a total gastrectomy. It was found that a splenectomy was not effective against advanced gastric cancer at stage III, and that the spleen should be retained for immunotherapy. Splenectomy for gastric cancer at terminal stage IV, particularly in combination with immunotherapy, produced not only augmentation of cellular immunity, but also increased survival.

Thalassemia is the most common human hereditary hemolytic anemia. Due to splenomegaly and hypersp-lenism, splenectomy can be used as a means of treatment for thalassemia. Various complications following splenectomy, however, especially thromboembolic complications are remarkable. This review summarizes the incidence, clinical manifestations and development time of thromboembolism. The pathogenesis of thromboembolism after splenectomy in thalassemia, such as abnormal platelet number and function, changes in red cell membrane, endothelial cell damage, dysfunction of other procoagulant and anticoagulant factors, and local factors associated with splenectomy are elaborated and the trategies to prevent and treat the thromboembolic events in thalassemia after splenectomy, including the attention to risk factors associated with splenectomy, a reassessment of splenectomy, regular blood transfusion to reduce the ratio of abnormal red blood cells, treatment with anticoagulant and antiplatelet drugs, application of hydroxyurea and stem cell transplantation are discussed.

Previous investigators have demonstrated that postinjury thrombocytosis is associated with an increase in thromboembolic (TE) risk. Increased rates of thrombocytosis have been found specifically in patients after splenectomy for trauma. We hypothesized that patients undergoing splenectomy (1) would demonstrate a more hypercoagulable profile during their hospital stay and (2) that this hypercoagulable state would be associated with increased TE events. This was a 14-month, prospective, observational trial evaluating serial rapid thrombelastography (rTEG) at 3 American College of Surgeons-verified, level 1 trauma centers. Inclusion criteria were highest-level trauma activation and arrival within 6 hours of injury. Exclusion criteria were 20% total body surface area. Serial rTEG (activated clotting time, k-time, α-angle, MA, lysis) and traditional coagulation testing (prothrombin time, partial thromboplastin time, fibrinogen and platelet count) were obtained at admission and then at 3, 6, 12, 24, 48, 72, 96, and 120 hours. Thromboembolic complications were defined as the development of deep-vein thrombosis, pulmonary embolism, acute myocardial infarction, or ischemic stroke during hospitalization. Patients were stratified into splenectomy versus nonsplenectomy cohorts. Univariate analysis was then conducted followed by longitudinal analysis using generalized estimating equations to evaluate the effects of time, splenectomy, and group-time interactions on changes in rTEG and traditional coagulation testing. We used an adjusted generalized estimating equation model to control for age, sex, ISS, admission blood pressure, base deficit, and hemoglobin. A total of 1,242 patients were enrolled; 795 had serial rTEG data. Of these, 605 had serial values >24 hours and made up the study population. Splenectomy patients were younger, more hypotensive, and in shock on arrival. Although there was no difference in 24-hour or 30-day mortality, splenectomy patients were more

In order to correlate the haematological changes which occur after splenectomy, with the presence or absence of residual splenic tissue, spleen scans using 99 Tcsup(m)-labelled red blood cells were performed in 36 patients who had had a splenectomy. Positive spleen scans were found in 44 per cent (8 out of 18) of patients who had undergone splenectomy for trauma and in 17 per cent (3 out of 18) of patients who had undergone elective splenectomy. No relationship was found between the presence of Howell-Jolly bodies, platelet counts, the levels of IgG, IgM and IgA and the scan result. It is concluded that these findings are due to the presence of splenunculi, whose incidence is more common than the 12 per cent usually quoted. (author)

Portal venous system thrombosis (PVST) is a common and potentially life-threatening complication of splenectomy for portal hypertension due to cirrhosis. A meta-analysis was conducted to study the necessity of pharmacologic prophylaxis of PVST after splenectomy and how to select the feasible treatment method. Articles were searched through the PubMed, EMBASE, Cochrane Library databases, and CNKI. Overall, 404 articles were initially identified, and 11 of them were eligible. Among these selected articles, 7 articles were associated with the necessity of anticoagulation for prevention of PVST, while 5 were about the drug selection. We first demonstrated that the incidence of PVST after splenectomy was significantly lower in patients who received the preventive measures than in those who did not (odds ratio [OR]: 0.22, 95% confidence interval [CI]: 0.13-0.39, P splenectomy and devascularization. Preventative use of anticoagulant drugs might decrease the incidence of PVST after splenectomy in patients with portal hypertension, new anticoagulant drugs such as low-molecular-weight heparin should be used, and early or combination use of anticoagulation drugs might lead to lower PVST incidence for patients.

Drugs and surgery can interfere with the biodistribution of radiopharmaceuticals and data about the effect of splenectomy on the metabolism of phytate-Tc-99m are scarce. This study aimed at evaluating the interference of splenectomy on phytate-Tc-99m biodistribution and liver function in rats. The SP group rats (n=6) underwent splenectomy. In group C (control) the animals were not operated on. After 15 days, all rats were injected with 0.1 mL of Tc-99m-phytate via orbital plexus (0.66 MBq). After 30 minutes, liver samples were harvested, weighed and the percentage of radioactivity per gram (%ATI/g) was determined by a Wizard Perkin-Elme gamma counter. The ATI%/g in splenectomized rats (0.99±0.02) was significantly higher than in controls (0.4±0.02), (p=0.034). ALT, AST and HDL were significantly lower in SP rats (p= 0.001) and leucocytosis was observed in SP rats. In conclusion, splenectomy in rats changed the hepatic biodistribution of Tc-99m-phytate and liver enzymatic activity. (author)

2014-08-01

Laparoscopic splenectomy has become the gold-standard procedure for normal to moderately enlarged spleens. However, the safety of laparoscopic splenectomy for patients with portal hypertension remains controversial. We carried out this systematic review to identify the feasibility and safety of laparoscopic splenectomy in treating portal hypertension. A systematic search for comparative studies that compared laparoscopic splenectomy with open splenectomy for portal hypertension was carried out. Studies were independently reviewed for quality, inclusion and exclusion criteria, demographic characteristics, and perioperative outcomes. Although laparoscopic splenectomy is associated with longer operating time, it offers advantages over the open procedure in terms of less blood loss, lower operative complications, earlier resumption of oral intake, and shorter posthospital stay. Therefore, laparoscopic splenectomy is a safe and feasible intervention for portal hypertension. © The Author(s) 2014.

The purpose of the study was to measure the effect of splenectomy on packed-cell transfusion requirement in children with sickle cell disease. Thirty-seven sickle cell children who underwent splenectomies between January 2000 and May 2006 at a children's hospital were reviewed. Data were collected 6 months preoperatively to 12 months postsplenectomy. Paired t test, analysis of variance, and multivariable regression analyses were performed. Of 37 children with median age 11 years (range, 2-18 years), 34 (21 males) had data that allowed analyses. Twenty-six had Hgb-SS, 5 had Hgb-SC, and 3 had Hgb S-Thal. Laparoscopic splenectomy was attempted in 36 and completed successfully in 34 (94% success). The number of units transfused decreased by 38% for 0 to 6 months and by 45% for 6 to 12 months postsplenectomy. Postoperatively, hematocrit levels increased and reticulocytes concurrently decreased with a reduction in transfusion clinic visits. The decrease in transfusion was not influenced by spleen weight, age, or hemoglobin type. Two children had acute chest syndrome (6%), and 1 had severe pneumonia (3%). Laparoscopic splenectomy can be successfully completed in sickle cell children. Splenectomy significantly reduces the packed red cell transfusion requirement and frequency of clinic visits, in sickle cell children for at least 12 months postoperatively.

Full Text Available ObjectiveTo investigate the possible risk factors for rebleeding after splenectomy and pericardial devascularization in the treatment of portal hypertension due to liver cirrhosis, and to provide a certain basis for reducing the incidence of digestive tract re-hemorrhage for these patients. MethodsA retrospective analysis was performed on 238 cirrhotic patients with portal hypertension who underwent splenectomy and pericardial devascularization in the First Hospital of Lanzhou University from December 2003 to December 2013. These patients were divided into postoperative rebleeding group (n=32 and non-bleeding group (n=206. Univariate analysis (t test or chi-square test and multivariate logistic regression analysis were performed to investigate the risk factors for rebleeding after splenectomy and pericardial devascularization. ResultsOf the 32 patients with postoperative rebleeding, 17 had esophagogastric variceal bleeding, 11 had bleeding due to portal hypertensive gastropathy, and 4 had stress ulcer bleeding. The univariate analysis showed that there were significant differences between the two groups in the following factors: Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, pathological changes of the gastric mucosa, platelet count, prothrombin time (PT, activated partial thromboplastin time (APTT, and presence of diabetes (all P<0.05. The multivariate logistic regression analysis suggested that the significant independent influential factors for postoperative rebleeding were presence of diabetes, Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, diffuse lesion of the gastric mucosa, PT, and APTT. ConclusionFor cirrhotic patients with portal hypertension, the appropriate methods for managing these risk factors are of great clinical significance for preventing rebleeding after splenectomy and pericardial devascularization.

Solitary metastasis of a malignancy to the spleen is rare, particularly for gastric cancer. Only a few case reports have documented isolated splenic metastasis from early gastric cancer. We describe a case of splenic metastasis from early gastric cancer. A 60-year-old man underwent a distal gastrectomy for early gastric cancer. It infiltrated the submucosa with pathological nodal involvement (pT1bN2M0, stage IIB). One year after the gastrectomy, an abdominal computed tomography scan showed a low-density lesion, 17 mm in diameter, at the upper pole of the spleen. Positron emission tomography/computed tomography showed focal accumulation of fluorine-18 fluorodeoxyglucose in the spleen without extrasplenic tumor dissemination or metastasis. We diagnosed splenic metastasis of gastric cancer, and performed a splenectomy. Histological examination confirmed moderately differentiated tubular adenocarcinoma and poorly differentiated adenocarcinoma (solid type) that was consistent with the features of the primary gastric cancer. The splenic tumor was pathologically and immunohistochemically diagnosed as a metastasis from the gastric carcinoma. More than 18 months after the splenectomy, the patient has had no evidence of recurrent gastric cancer. When solitary metastasis to the spleen is suspected during the postoperative follow-up of a patient with gastric cancer, a splenectomy is a potentially effective treatment.

To clarify the role of splenectomy in total gastrectomy for proximal gastric cancer. Splenectomy in total gastrectomy is associated with increased operative morbidity and mortality, but its survival benefit is unclear. Previous randomized controlled trials were underpowered and inconclusive. We conducted a multiinstitutional randomized controlled trial. Proximal gastric adenocarcinoma of T2-4/N0-2/M0 not invading the greater curvature was eligible. During the operation, surgeons confirmed that R0 resection was possible with negative lavage cytology, and patients were randomly assigned to either splenectomy or spleen preservation. The primary endpoint was overall survival (OS) and the secondary endpoints were relapse-free survival, operative morbidity, operation time, and blood loss. The trial was designed to confirm noninferiority of spleen preservation to splenectomy in OS with a noninferiority margin of the hazard ratio as 1.21 and 1-sided alpha of 5%. Between June 2002 and March 2009, 505 patients (254 splenectomy, 251 spleen preservation) were enrolled from 36 institutions. Splenectomy was associated with higher morbidity and larger blood loss, but the operation time was similar. The 5-year survivals were 75.1% and 76.4% in the splenectomy and spleen preservation groups, respectively. The hazard ratio was 0.88 (90.7%, confidence interval 0.67-1.16) (splenectomy should be avoided as it increases operative morbidity without improving survival.

Full Text Available Asplenic patients have a lifelong risk of overwhelming post-splenectomy infection and have been reported to have low numbers of peripheral blood IgM memory B cells. The clinical value of quantitation of memory B cells as an indicator of splenic abnormality or risk of infection has been unclear. To assess changes in B cell sub-populations after splenectomy we studied patients recruited to a spleen registry (n = 591. A subset of 209 adult asplenic or hyposplenic subjects, and normal controls (n = 140 were tested for IgM memory B cells. We also determined a changes in IgM memory B cells with time after splenectomy using the cross-sectional data from patients on the registry and b the kinetics of changes in haematological markers associated with splenectomy(n = 45. Total B cells in splenectomy patients did not differ from controls, but memory B cells, IgM memory B cells and switched B cells were significantly (p<0.001 reduced. The reduction was similar for different indications for splenectomy. Changes of asplenia in routine blood films including presence of Howell-Jolly bodies (HJB, occurred early (median 25 days and splenectomy associated thrombocytosis and lymphocytosis peaked by 50 days. There was a more gradual decrease in IgM memory B cells reaching a stable level within 6 months after splenectomy. IgM memory B cells as proportion of B cells was the best discriminator between splenectomized patients and normal controls and at the optimal cut-off of 4.53, showed a true positive rate of 95% and false positive rate of 20%. In a survey of 152 registry patients stratified by IgM memory B cells around this cut-off there was no association with minor infections and no registry patients experienced OPSI during the study. Despite significant changes after splenectomy, conventional measures of IgM memory cells have limited clinical utility in this population.

Although splenic angioembolization (SAE) has been introduced and adopted in many trauma centers, the appropriate selection for and utility of SAE in trauma patients remains under debate. This study examined the outcomes of proximal SAE as part of a management algorithm for adult traumatic splenic injury compared with splenectomy. A retrospective cohort analysis was performed on all hemodynamically stable (HDS) blunt trauma patients with isolated splenic injury and computed tomographic (CT) evidence of active contrast extravasation that presented to a level 1 Trauma Center over a period of 5 years. The cohorts were defined by two separate 30 month periods and included 78 patients seen before (group I) and 76 patients seen after (group II) the introduction of an institutional SAE protocol. Demographics, splenic injury grade, and outcomes of the two groups were compared using Student's t test, or chi2 test. Analysis was by intention-to-treat. Six hundred eighty-two patients with blunt splenic injury were identified; 154 patients (29%) were HDS with CT evidence of active contrast extravasation. Group I (n = 78) was treated with splenectomy and group II (n = 76) was treated with proximal SAE. There was no difference in age (33 +/- 14 vs. 37 +/- 17 years), Injury Severity Score (31 +/- 13 vs. 29 +/- 11), or mortality (18% vs. 15%) between the two groups. However, the incidence of Adult Respiratory Distress Syndrome (ARDS) was 4-fold higher in those patients that underwent proximal SAE compared with those that underwent splenectomy (22% vs. 5%, p = 0.002). Twenty two patients failed nonoperative management (NOM) after SAE. This failure appeared to be directly related to the grade of splenic organ injury (grade I and II: 0%; grade III: 24%; grade IV: 53%; and grade V: 100%). Introduction of proximal SAE in NOM of HDS splenic trauma patients with active extravasation did not alter mortality rates at a Level 1 Trauma Center. Increased incidence of ARDS and association of

Our aim was to evaluate the clinical value of splenectomy as a treatment for relapsed hemophagocytic lymphohistiocytosis (HLH) of unknown cause in adults. We retrospectively reviewed the clinical data from medical records of 19 adults with relapsed HLH of unknown cause treated with splenectomy in our institution from June 2007 to March 2014. To rule out possible underlying diseases, including infection, autoimmune disease, neoplasms, and primary HLH, the patients had undergone examinations including F18 fluoro-2-deoxyglucose positron emission tomography/computed tomography, HLH-associated gene defects, and lymph node biopsies. Twelve patients (63.2%) achieved partial responses (PR), whereas seven patients (36.8%) had no response (NR) prior to splenectomy. Infection and hemorrhage were the main complications of splenectomy. Eighteen cases were evaluable after follow-up. Seven cases with histopathologic diagnoses of lymphoma had received chemotherapy, four of whom had achieved complete responses (CR), one PR, and two NR. Maintenance treatment was ceased 2 or 3 months after splenectomy in the other 11 cases, five of whom had CR, four PR, and two NR. Eleven of 18 cases (61.1%) survived with a median follow-up of 25 months (range 3-79 months) for survivors. Twelve- and 36-month progression-free survival rates were 48 and 24%, respectively; 12- and 36-month overall survival rates were 57 and 25%, respectively. Median survival time was 22 months. Our results indicate splenectomy may be an effective means of diagnosis and treatment of relapsed HLH of unknown cause. Further study is required to establish the mechanism and value of splenectomy in this disease.

Laparoscopic partial splenectomy (LPS) theoretically maintains long-term splenic immune function for children with hereditary spherocytosis (HS). Our goal was to review our results after LPS and to determine if specific genetic mutations influence outcome. All children with HS undergoing LPS between 2005 and 2016 were reviewed. Thirty-one children underwent LPS (16 male) at a median age of 9 (range 2-18) years. All experienced an increase in hemoglobin and decrease in reticulocyte count early after LPS and at last follow-up. Twenty-two were sent for genetic analysis. Mutations in α-spectrin, β-spectrin, and Ankyrin were identified in 6, 5, and 11 patients, respectively. Gene mutation was not correlated with complications, perioperative transfusion, length of hospital stay, or median hemoglobin, platelet, or reticulocyte counts. Three children required completion splenectomy at 10.9, 6.9, and 3.2years post-LPS, each with a different gene mutation. LPS is effective in reversing anemia and reducing reticulocytosis. So far less than 10% have required completion splenectomy, and those children did benefit from delaying the risks of asplenia. In this preliminary analysis, genetic mutation did not influence outcome after LPS. A larger multicenter study is necessary to further investigate potential correlations with specific genetic mutations. Prognosis Study. IV. Copyright © 2018. Published by Elsevier Inc.

Peritoneal carcinomatosis-like implants of extramedullary hematopoiesis. An insolite occurrence during splenectomy for myelofibrosis

Full Text Available Introduction: Primary myelofibrosis (MF is a myeloproliferative neoplasm that results in debilitating constitutional symptoms, splenomegaly, and cytopenias. In patients with symptomatic splenomegaly, splenectomy remains a viable treatment option for MF patients with medically refractory symptomatic splenomegaly that precludes the use of ruxolitinib. Case presentation: We present the clinical case of a patient who was admitted to our Department to perform a splenectomy in MF as a therapeutic step prior to an allogeneic stem cell transplantation (ASCT. A laparotomic splenectomy and excision of whitish wide-spread peritoneal and omental nodulations was performed. There were no operative complications and the surgery was completed with minimal blood loss. The histopathological exam revealed an extramedullary hematopoiesis in both spleen and peritoneal nodules. Conclusion: In primary myelofibrosis it must always be kept in mind the possible presence of peritoneal implants of extramedullary hematopoiesis and ascites of reactive genesis. We report a rare case of peritoneal carcinomatosis-like implants of extramedullary hematopoiesis found at splenectomy for MF.

Review of the Association between Splenectomy and Chronic Thromboembolic Pulmonary Hypertension.

Recent evidence suggests that there may be a link between splenectomy and the later development of pulmonary hypertension, in particular World Health Organization group IV pulmonary hypertension (chronic thromboembolic pulmonary hypertension). Epidemiological studies have demonstrated an odds ratio as high as 18 for the development of chronic thromboembolic pulmonary hypertension after splenectomy in comparison with matched control subjects who have not undergone splenectomy. The mechanisms governing the association between removal of the spleen and the subsequent development of chronic thromboembolic pulmonary hypertension remain incompletely understood; however, recent advances in understanding of coagulation homeostasis have shed some light on this association. Splenectomy increases the risk of venous thromboembolic disease, a necessary precursor of chronic thromboembolic pulmonary hypertension, by generating a prothrombotic state. This prothrombotic state likely results from a reduction in the removal of circulating procoagulant factors from the bloodstream after splenectomy. Although much is to be learned, circulating microparticles have emerged as the most likely mediator for the development of thrombosis after splenectomy. Apparently because of a reduction in reticuloendothelial cell clearance, microparticle levels are elevated in patients after splenectomy. Elevated circulating microparticle levels have been linked to thromboembolism and pulmonary hypertension in a dose-dependent fashion. It is important for health care providers to be aware of the link between splenectomy and chronic thromboembolic pulmonary hypertension. We are optimistic that clarification of the exact mechanisms that govern this association will yield clinical guidelines and potential treatments.

Platelet life-span was studied in 165 patients (including 25 children) with chronic idiopathic thrombocytopenic purpura (of at least one year duration) using 111 indium-oxinate-labeled autologous platelets. The site of platelet destruction was not correlated with age, severity of the disease or presence of immunologic anomalies; this site was characteristic of each individual and remained unchanged in a given patient when the test was repeated several times. Splenectomy was performed in 79 patients (at the discretion of physicians who elected splenectomy in 63% of patients with splenic destruction versus 26% only of patients with hepatic destruction). A very close correlation was found between site of destruction and efficiency of splenectomy. However, 13% of initially improved patients developed a recurrence. Spontaneous improvement was seen in only 8 of the non-splenectomized patients with long-term follow-ups (1-5 years) [fr

Selective spleen scintigraphy to evaluate frequency of splenosis after posttraumatic splenectomy

International Nuclear Information System (INIS)

Loew, A.; Tischler, E.; Mahlstedt, J.; Wolf, F.; Meier, H.

1981-01-01

In 60 patients having had posttraumatic splenectomy between 9 months and 12 years ago frequency of splenosis was investigated in comparison to immunological and hematological parameters. Selective spleen scintigraphy was performed with sup(99m)-Tc-labelled heat-damaged auto-erythrocytes. In 46,7% of the patients splenosis was found without age dependence. Between patients with and without splenosis no significant differences concerning the immunological and hematological parameters were seen. Therefore, the lack of pathological manifestations after posttraumatic splenectomy is not to be related to autotransplantation of splenic tissue. (orig.) [de

Splenectomy continues to find common therapeutic indications for hematologic disorders. In addition, recently it is also performed in surgical clinics to assist diagnose of some illnesses. Gaucher's disease, especially Type I, is the most frequently encountered lysosomal storage disorder in man. Manifestations of it are highly variable. The most frequently found symptoms include splenomegaly with anaemia and thrombocytopenia, mostly due to hypersplenism, hepatomegaly and bone disease. Four patients were reported in the present study. Three of them were easily diagnosed with Gaucher's disease via bone marrow cytology, and one with Gaucher's disease was detected by pathological examination following the splenectomy. For the pouse of diagnosis of the Gaucher's disease, performing surgery is generally not necessary. However, for the cases of difficult to diagnose by classical methods, the corect diagnosis of Gaucher's disease can only be made by a special operation.

Splenectomy Improves Hemostatic and Liver Functions in Hepatosplenic Schistosomiasis Mansoni.

Directory of Open Access Journals (Sweden)

Luiz Arthur Calheiros Leite

Full Text Available Schistosomiasis mansoni is a chronic liver disease, in which some patients (5-10% progress to the most severe form, hepatosplenic schistosomiasis. This form is associated with portal hypertension and splenomegaly, and often episodes of gastrointestinal bleeding, even with liver function preserved. Splenectomy is a validated procedure to reduce portal hypertension following digestive bleeding. Here, we evaluate beneficial effects of splenectomy on blood coagulation factors and liver function tests in hepatosplenic schistosomiasis mansoni compared to non-operated patients.Forty-five patients who had undergone splenectomy surgery were assessed by laboratory analyses and ultrasound examination and compared to a non-operated group (n = 55. Blood samples were obtained for liver function tests, platelet count and prothrombin time. Coagulation factors (II, VII, VIII, IX and X, protein C and antithrombin IIa, plasminogen activator inhibitor-1 were measured by routine photometric, chromogenic or enzyme-linked immunosorbent assays, while hyperfibrinolysis was defined by plasminogen activator inhibitor-1 levels. Both groups had similar age, gender and pattern of periportal fibrosis. Splenectomized patients showed significant reductions in portal vein diameter, alkaline phosphatase and bilirubin levels compared to non-operated patients, while for coagulation factors there were significant improvement in prothrombin, partial thromboplastin times and higher levels of factor VII, VIII, IX, X, protein C and plasminogen activator inhibitor-1.This study shows that the decrease of flow pressure in portal circulation after splenectomy restores the capacity of hepatocyte synthesis, especially on the factor VII and protein C levels, and these findings suggest that portal hypertension in patients with hepatosplenic schistosomiasis influences liver functioning and the blood coagulation status.

We describe our experience with what is, to our knowledge, the first case of robotic assisted ex vivo partial splenectomy with auto-transplantation for a benign non parasitic cyst. The patient is a 32 year-old female with a giant, benign splenic cyst causing persistent abdominal pain. Preoperative imaging showed a cystic lesion measuring 8.3 × 7.6 cm, in the middle portion of the spleen. Due to the central location of the bulky lesion a partial splenectomy was not feasible. As an alternative to a total splenectomy, a possible reimplantation of hemi-spleen after bench surgery was offered. We proceeded with a robotic total splenectomy and bench hemisplenectomy, preserving the lower pole and a portion of the middle segment of the organ. A robotic reconstruction of the splenic vessels was then performed intra-abdominally. The reperfusion was optimal. The total operative time was 305 min, with 78 min of robotic time. Postoperative ultrasound confirmed a patent arterial and venous flow. The postoperative course was uneventful and the patient was discharged on postoperative day 4. The pathology report was consistent with epithelial cyst of the spleen. The patient is doing well at 6-month follow-up. The optimized vision and dexterity provided by the robotic system allowed a safe and precise reconstruction of the splenic vessels, even in a deep and narrow operative field. Partial splenectomy with autotransplantation of the organ was thus achieved, avoiding a total splenectomy in a young patient.

Ambriz, P.; Munoz, R.; Quintanar, E.; Sigler, L.; Aviles, A.; Pizzuto, J.

1985-01-01

Accessory spleens were sought in 28 patients who had undergone splenectomy for chronic idiopathic thrombocytopenic purpura (ITP), using a variety of techniques. Abdominal scintigraphy with autologous erythrocytes labeled with Tc-99m and opsonized with anit-D IgG (radioimmune method) proved to be most useful, clearly demonstrating one or more accessory spleens in 12 cases (43%). Computed tomography (CT) was also helpful. Four out of five patients demonstrated an increased platelet count following surgery, the effectiveness of which was illustrated by the radioimmune scan. Patients who have had splenectomy for chronic ITP should be scanned using radioimmune techniques and CT to determine whether an accessory spleen is present

The Toll-like receptor 4(TLR4)/nuclear factor kappa B NF-κB inflammatory pathway contributes to secondary inflammation in many diseases including stroke. Moreover, the neuroprotective effect of splenectomy in stroke is supported by a vast body of experimental evidence. Nevertheless, the underlying mechanism(s) by which splenectomy enhance neuroprotection in stroke is still poorly understood. Our study aimed to investigate whether post-ischemic splenectomy modulate the TLR4/NF-κB inflammatory pathway in stroke. Immunohistochemistry was used to evaluate the levels of TLR4 and NF-κB expression in brain areas (parietal lobe, hippocampus and striatum) of rats that underwent: MCAO-splenectomy surgery (MS ); MCAO surgery without splenectomy (MCAO control or MC); Sham MCAO and splenectomy surgery (sham control group or SC group respectively. Apoptosis in these areas was assessed by TUNEL detection technique. The levels of TLR4 and NF-κB expression were significantly reduced in splenectomized rats relative to the MS group (Psplenectomy in ischemic stroke. Our results suggest that such an effect might be due to the inhibition of theTLR4/NF-κB inflammatory pathway. Copyright © 2016 Elsevier B.V. All rights reserved.

Clinical studies suggest that splenectomy improves liver function in cirrhotic patients, but the influence of splenectomy on stem cell transplantation is poorly understood. This study investigated the effect of splenectomy on stem cell infusion and elucidated its mechanism. Rat adipose tissue-derived mesenchymal stem cells were infused into cirrhosis rats with or without splenectomy, followed by the assessment of the in vivo distribution of stem cells and pathological changes. Stromal cell-derived factor-1 and hepatocyte growth factor expression were also investigated in splenectomized cirrhosis patients and rats. Splenectomy, prior to cell infusion, improved liver function and suppressed fibrosis progression more efficiently than cell infusion alone in the experimental cirrhosis model. Stromal cell-derived factor-1 and hepatocyte growth factor levels after splenectomy were increased in patients and rats. These upregulated cytokines significantly facilitated stem cell motility, migration and proliferation in vitro. C-X-C chemokine receptor type 4 neutralization weakened the promotion of cell migration by these cytokines. The infused cells integrated into liver fibrosis septa and participated in regeneration more efficiently in splenectomized rats. Direct coculture with stem cells led to inhibition of hepatic stellate cell proliferation. In addition, hepatocyte growth factor induced hepatic stellate cell apoptosis via the c-jun N-terminal kinase-p53 pathway. Splenectomy prior to cell infusion enhanced the therapeutic effect of stem cells on cirrhosis, which involved upregulation of stromal cell-derived factor-1 and hepatocyte growth factor after splenectomy. © 2015 John Wiley & Sons A/S.

Although preservation of the spleen following abdominal trauma and spleen-preserving surgical procedures have become gold standards, about 22,000 splenectomies are still conducted annually in the USA. Infections, mostly by encapsulated organisms, are the most well-known complications following splenectomy. Recently, thrombosis and cancer have become recognized as potential adverse outcomes post-splenectomy. Among more than 4 million hospitalized USA veterans, we assessed incidence and mortality due to infections, thromboembolism, and cancer including 8,149 cancer-free veterans who underwent splenectomy with a follow-up of up to 27 years. Relative risk estimates and 95% confidence intervals were calculated using time-dependent Poisson regression methods for cohort data. Splenectomized patients had an increased risk of being hospitalized for pneumonia, meningitis, and septicemia (rate ratios=1.9–3.4); deep venous thrombosis and pulmonary embolism (rate ratios=2.2); certain solid tumors: buccal, esophagus, liver, colon, pancreas, lung, and prostate (rate ratios =1.3–1.9); and hematologic malignancies: non-Hodgkin lymphoma, Hodgkin lymphoma, multiple myeloma, acute myeloid leukemia, chronic lymphocytic leukemia, chronic myeloid leukemia, and any leukemia (rate ratios =1.8–6.0). They also had an increased risk of death due to pneumonia and septicemia (rate ratios =1.6–3.0); pulmonary embolism and coronary artery disease (rate ratios =1.4–4.5); any cancer: liver, pancreas, and lung cancer, non-Hodgkin lymphoma, Hodgkin lymphoma, and any leukemia (rate ratios =1.3–4.7). Many of the observed risks were increased more than 10 years after splenectomy. Our results underscore the importance of vaccination, surveillance, and thromboprophylaxis after splenectomy.

Open partial splenectomy provides reversal of anemia and relief of symptomatic splenomegaly while theoretically retaining splenic immune function for hereditary spherocytosis. We recently developed a laparoscopic approach for partial splenectomy. The purpose of the present study is to compare the outcomes in a group of patients undergoing laparoscopic partial splenectomy (LPS) with those in a group of children undergoing laparoscopic total splenectomy (LTS) over the same period. Systematic chart review was conducted of all children with hereditary spherocytosis who had LTS or LPS from 2000 to 2006 at the Hospital for Sick Children, Toronto, Ontario, Canada. T tests were used for continuous data, and chi(2) for proportional data; P value of less than .05 was considered significant. There were 9 patients (14 males) in each group. Groups were similar in sex, age, concomitant cholecystectomy, and preoperative hospitalizations, transfusions, and spleen size. Estimated blood loss was greater in the LPS group (188 + 53 vs 67 + 17 mL; P = .02), but transfusion requirements were similar (1/9 vs 0/9). Complication rate was similar between groups. The LPS group had higher morphine use (4.1 + 0.6 vs 2.4 + 0.2 days; P = .03), greater time to oral intake (4.4 + 0.7 vs 2.0 + 0.2 days; P = .01), and longer hospital stay (6.3 + 1.0 vs 2.7 + 0.3 days; P = .005) than the LTS group. Nuclear scan 6 to 8 weeks postoperatively demonstrated residual perfused splenic tissue in all LPS patients. No completion splenectomy was necessary after a mean follow-up of 25 months. These data suggest that LPS is as effective as LTS for control of symptoms. However, LPS is associated with more pain, longer time to oral intake, and longer hospital stay. These disadvantages may be balanced by retained splenic immune function, but further studies are required to assess long-term splenic function in these patients.

Full Text Available Abstract Background Postoperative pancreas fistula (POPF is a major complication after total gastrectomy with splenectomy. We retrospectively studied the effects of upper abdominal shape on the development of POPF after gastrectomy. Methods Fifty patients who underwent total gastrectomy with splenectomy were studied. The maximum vertical distance measured by computed tomography (CT between the anterior abdominal skin and the back skin (U-APD and the maximum horizontal distance of a plane at a right angle to U-APD (U-TD were measured at the umbilicus. The distance between the anterior abdominal skin and the root of the celiac artery (CAD and the distance of a horizontal plane at a right angle to CAD (CATD were measured at the root of the celiac artery. The CA depth ratio (CAD/CATD was calculated. Results POPF occurred in 7 patients (14.0% and was associated with a higher BMI, longer CAD, and higher CA depth ratio. However, CATD, U-APD, and U-TD did not differ significantly between patients with and those without POPF. Logistic-regression analysis revealed that a high BMI (≥25 and a high CA depth ratio (≥0.370 independently predicted the occurrence of POPF (odds ratio = 19.007, p = 0.002; odds ratio = 13.656, p = 0.038, respectively. Conclusion Surgical procedures such as total gastrectomy with splenectomy should be very carefully executed in obese patients or patients with a deep abdominal cavity to decrease the risk of postoperative pancreatic fistula. BMI and body shape can predict the risk of POPF simply by CT.

This study investigated whether there was an association between splenectomy and pulmonary tuberculosis. This was a case-control study using the database of the Taiwan National Health Insurance Programme. We identified 18 960 patients (aged 20 years or older) with newly diagnosed pulmonary tuberculosis as the case group and 73 988 participants without pulmonary tuberculosis as the control group from 1998 to 2011. Both groups were matched for sex, age (per 5 years) and index year of pulmonary tuberculosis diagnosis. The risk of pulmonary tuberculosis associated with splenectomy and other co-morbidities was estimated. After controlling for confounders, multivariable logistic regression analysis showed that the odds of pulmonary tuberculosis were 1.91 in patients with splenectomy (95% CI 1.06-3.44), compared with the participants without splenectomy. Chronic obstructive pulmonary diseases (OR 3.07, 95% CI 2.94-3.21), pneumoconiosis (OR 2.20, 95% CI 1.90-2.56), chronic kidney diseases (OR 1.49, 95% CI 1.33-1.67), diabetes mellitus (OR 1.57, 95% CI 1.50-1.64) and chronic liver diseases (OR 1.31, 95% CI 1.25-1.37) were associated with an increased risk of pulmonary tuberculosis. The sub-analysis demonstrated that the odds of pulmonary tuberculosis were 4.81 (95% CI 2.31-10.0) for patients co-morbid with splenectomy and any of the above diseases. Splenectomy is associated with a 1.9-fold increased risk of pulmonary tuberculosis in Taiwan. There is a synergistic effect between splenectomy and other co-morbidities on the risk of pulmonary tuberculosis. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

The purpose of this study was to define the hematologic response to total splenectomy (TS) or partial splenectomy (PS) in children with hereditary spherocytosis (HS) or sickle cell disease (SCD). The Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium registry collected hematologic outcomes of children with CHA undergoing TS or PS to 1 year after surgery. Using random effects mixed modeling, we evaluated the association of operative type with change in hemoglobin, reticulocyte counts, and bilirubin. We also compared laparoscopic to open splenectomy. The analysis included 130 children, with 62.3% (n=81) undergoing TS. For children with HS, all hematologic measures improved after TS, including a 4.1g/dl increase in hemoglobin. Hematologic parameters also improved after PS, although the response was less robust (hemoglobin increase 2.4 g/dl, p<0.001). For children with SCD, there was no change in hemoglobin. Laparoscopy was not associated with differences in hematologic outcomes compared to open. TS and laparoscopy were associated with shorter length of stay. Children with HS have an excellent hematologic response after TS or PS, although the hematologic response is more robust following TS. Children with SCD have smaller changes in their hematologic parameters. These data offer guidance to families and clinicians considering TS or PS. Copyright © 2016 Elsevier Inc. All rights reserved.

Splenectomy in a patient with treatment-resistant visceral leishmaniasis: a case report

Directory of Open Access Journals (Sweden)

Robson Azevedo Dutra

2012-02-01

Full Text Available Visceral leishmaniasis (VL, also known as Kala-azar, is a systemic infection caused by a protozoan (Leishmania and, in its classic form, is a serious illness associated with malnutrition, anemia, hepatosplenomegaly, infectious processes and coagulopathies. The effect of splenectomy in patients with visceral leishmaniasis is not well defined; however, it is known that the spleen is the largest reservoir of infected cells belonging to the reticulo endothelial system. Therefore, the surgical procedure is an option for the debulking of parasites, providing a cure for refractory VL and minimizing the complications of hypersplenism.

Indications for splenectomy (SP) during whole liver transplantation (LT) remain controversial and SP is often avoided because of common complications. We aimed to evaluate specific complications of these combined procedures. Data were retrospectively analysed. Splenectomy was performed in patients with splenorenal shunt and/or splenic artery aneurysms or hypersplenism. Patients undergoing simultaneous transplantation and splenectomy (LTSP group) were matched to a non-splenectomy group (LT group). Between 1994 and 2013, we included 47 and 94 patients in LTSP and LT groups, respectively. The LTSP patients had a higher rate of pre-LT portal vein thrombosis (PVT). The LTSP group had a longer operative time and greater blood loss. Mean follow-up was 101 months and 5-year survivals were identical (LTSP 85% vs LT 88%, p = 0.831). Hospital morbidity and rejection incidence were comparable, whereas de novo PVT (34% vs 2%, p Splenectomy during LT is technically demanding and exposes recipients to a higher thrombosis rate, therefore portal vein patency must be specifically assessed postoperatively. In selected recipients, SP can be performed without increased mortality but at the price of worsening outcome as evidenced by greater risk of infection and PVT.

Iron-rich transfusions and/or a compensatory increase in iron absorption ultimately result in iron loading in patients with β-thalassaemia. Hence, without iron chelation, iron accumulates relentlessly. Deferiprone has been shown to be capable of reducing the iron burden in patients with b-thalassaemia. However, there is wide interpatient variation in deferiprone-induced urinary iron excretion (UIE). We hypothesized that splenectomy and iron status might influence the pharmacokinetic profiles of deferiprone in patients with β-thalassaemia/haemoglobin E, and the present study was aimed at examining this hypothesis. Thirty-one patients with β-thalassaemia/haemoglobin E (20 splenecto-mized and 11 non-splenectomized patients) were enrolled in the study. After an overnight fast, the subjects received a single oral dose of deferiprone 25 mg/kg of body weight. Blood samples were collected pre-dosing and at 15, 30, 45, 60, 90, 120, 180, 240, 300, 360 and 480 minutes after dosing. Urine output was pooled and collected at 0-2, 2-4, 4-8, 8-12 and 12-24 hour intervals. Serum and urine concentrations of deferiprone and its metabolite deferiprone glucuronide were determined using a validated high-performance liquid chromatography method. Serum deferiprone-chelated iron and UIE were determined using a validated colourimetric method. No significant difference in the pharmacokinetic parameters of non-conjugated deferiprone was observed between splenectomized and non-splenectomized patients. However, the maximum serum concentration (C max ) and the area under the serum concentration-time curve (AUC) from time zero to infinity (AUC∞) values of deferiprone glucuronide were significantly lower (both p values of serum deferiprone-chelated iron, as well as UIE, were significantly higher (p values 7.1 µmol/L, 1645 mmol · min/L and 77.1 mmol, respectively) than in non-splenectomized patients (median values 3.1 µmol/L, 545 mmol · min/L and 12.5 µmol, respectively).

Laparoscopic gastric devascularization(Lap GDS) and splenectomy (SPL) for gastric varices is technically challenging because of highly developed collateral vessels and bleeding tendency. We investigated the feasibility of customization of Lap GDS and SPL based on CT vascular anatomy. We analyzed 61 cirrhotic patients with gastric varices who underwent Lap GDS and SPL between 2006 and 2014. Lap GDS was customized according to the afferent feeding veins (left gastric vein (LGV) and/or posterior gastric vein (PGV)/short gastric vein (SGV)) and efferent drainage veins (gastrorenal shunt and/or gastrophrenic shunt, or numerous retroperitoneal veins) based on CT imaging. Thirty-four patients with efferent drainage veins suitable for balloon-occluded retrograde transvenous obliteration (B-RTO) underwent B-RTO instead of surgical GDS, with subsequent Lap SPL. Among 27 patients with gastric varices unsuitable for B-RTO, 15 patients with PGV/SGV underwent Lap GDS of the greater curvature and SPL, and 12 patients with LGV or LGV/PGV/SGV underwent Lap GDS of the greater and lesser curvature and SPL. The mean operation time was 294 min and mean blood loss was 198 g. There was no mortality or severe morbidity. Gastric varices were eradicated in all 61 patients, with no bleeding or recurrence during a mean follow-up of 55.9 months. The cumulative 3-, 5-, and 7-year survival rates were 92, 82, and 64%, respectively. Lap GDS and SPL customized based on CT vascular anatomy is a safe and effective procedure for treating gastric varices.

To evaluate the association between previous splenectomy and gastric dilatation-volvulus (GDV) in dogs. Multi-institutional retrospective case-control study. Animals-151 dogs treated surgically for GDV and 302 control dogs with no history of GDV. Computerized records of dogs evaluated via exploratory laparotomy or abdominal ultrasonography were searched, and dogs with GDV and dogs without GDV (control dogs) were identified. Two control dogs were matched with respect to age, body weight, sex, neuter status, and breed to each dog with GDV. Data were collected on the presence or absence of the spleen for both dogs with GDV and control dogs. Conditional logistic regression analysis was used to investigate the association of previous splenectomy with GDV. 6 (4%) dogs in the GDV group and 3 (1%) dogs in the control group had a history of previous splenectomy. The odds of GDV in dogs with a history of previous splenectomy in this population of dogs were 5.3 times those of dogs without a history of previous splenectomy (95% confidence interval, 1.1 to 26.8). For the patients in the present study, there was an increased odds of GDV in dogs with a history of splenectomy. Prophylactic gastropexy may be considered in dogs undergoing a splenectomy, particularly if other risk factors for GDV are present.

Full Text Available PURPOSE: Over the past 21 years, we have performed more than 200 subtotal splenectomies, in which the upper splenic pole vascularized only by the gastrosplenic pole vascularized only by the gastrosplenic vessels is preserved, to treat different pathologic conditions. A meticulous follow-up of the postoperative results of this procedure is of fundamental importance. METHODS: All patients undergoing subtotal splenectomy were invited to be reviewed. A total of 86 patients who had undergone surgery 1 to 20 years ago were gathered; the surgical procedure was performed for one of the following conditions: portal hypertension due to schistosomiasis (n = 43, trauma (n = 31, Gaucher's disease (n = 4, myeloid hepatosplenomegaly due to myelofibrosis (n = 3, splenomegalic retarded growth and sexual development (n = 2, severe pain due to splenic ischemia (n = 2 and pancreatic cystadenoma (n = 1. Patients underwent a hematologic exam, an immunologic assessment, abdominal ultrasonography, computed tomography, scintigraphy and endoscopy. RESULTS: Increased white blood cell count and platelets were the only hematological abnormalities. No immunologic deficit was found. Esophageal varices were still present in patients who underwent surgery because of portal hyperension although without rebleeding. The ultrasound, tomography and scintigraphy exams confirmed the presence of functional splenic remnants without significant size alteration. CONCLUSIONS: Subtotal splenectomy seems to be a safe procedure that can be useful in treating conditions involving the spleen. The functions of the splenic remnants are preserved during long periods of time.OBJETIVO: Durante 21 anos, realizamos mais de 200 esplenectomias subtotais para tratar diferentes condições patológicas.

Purpose The purpose of this study was to define the hematologic response to total splenectomy (TS) or partial splenectomy (PS) in children with hereditary spherocytosis (HS) or sickle cell disease (SCD). Methods The Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium registry collected hematologic outcomes of children with CHA undergoing TS or PS to 1 year after surgery. Using random effects mixed modeling, we evaluated the association of operative type with change in hemoglobin, reticulocyte counts, and bilirubin. We also compared laparoscopic to open splenectomy. Results The analysis included 130 children, with 62.3% (n = 81) undergoing TS. For children with HS, all hematologic measures improved after TS, including a 4.1 g/dl increase in hemoglobin. Hematologic parameters also improved after PS, although the response was less robust (hemoglobin increase 2.4 g/dl, p < 0.001). For children with SCD, there was no change in hemoglobin. Laparoscopy was not associated with differences in hematologic outcomes compared to open. TS and laparoscopy were associated with shorter length of stay. Conclusion Children with HS have an excellent hematologic response after TS or PS, although the hematologic response is more robust following TS. Children with SCD have smaller changes in their hematologic parameters. These data offer guidance to families and clinicians considering TS or PS. PMID:26613837

Acute Central Retinal Vein Occlusion Secondary to Reactive Thrombocytosis after Splenectomy

Directory of Open Access Journals (Sweden)

Nursen Oncel Acir

2014-01-01

Full Text Available The diagnosis and treatment of central retinal vein occlusion was reported in a young patient. Central retinal vein occlusion was probably related to secondary to reactive thrombocytosis after splenectomy. The patient was treated with steroids for papilledema and administered coumadin and aspirin. The symptoms resolved, and the findings returned to normal within three weeks. Current paper emphasizes that, besides other well-known thrombotic events, reactive thrombocytosis after splenectomy may cause central retinal vein occlusion, which may be the principal symptom of this risky complication. Thus, it can be concluded that followup for thrombocytosis and antithrombotic treatment, when necessary, are essential for these cases.

Laparoscopic Splenectomy for Benign Hematological Disorders in Adults: A Systematic Review.

Since its introduction in the early 1990s, laparoscopic splenectomy (LS) has gained worldwide acceptance for spleen removal, especially in hematological patients. The present review summarizes the current knowledge and results of LS for the treatment of benign hematological diseases in adults. A MEDLINE/PubMed database research was performed using the terms: "laparoscopic splenectomy" OR "laparoscopy" OR "splenectomy" AND "hematological disorders" OR "hematological disease" OR "hematology" AND "adults" as key words. We set our analysis starting date as January 1st 2010 and the end date as December 31st 2016. We identified 247 relative articles. All the references from the identified articles were searched for relevant information. Twenty-seven articles were deemed appropriate for our analysis. LS was found to be feasible and safe in the majority of patients with benign hematological disorders, with a mortality rate ranging from 0% to less than 4% and the postoperative complications rate from 0% to 35.7%. The conversion rate was also very low (4%) and response (complete or partial) was achieved in more than 80% of patients. Lateral approach with four trocars was the most commonly used approach with concommitant cholecystectomy being correlated with increased operative time and morbidity. Current literature holds that whenever splenectomy is required for the treatment of hematological disorders in adults, a laparoscopic approach should be offered as the gold standard. However, to strengthen the clinical evidence in favor of LS, more high-quality clinical trials on several issues of the procedure are necessary.

2010-01-01

To establish if splenectomy increases the incidence of gastric dilatation and volvulus (GDV) in dogs. Two case-series studies of cases and controls were performed. Records of dogs that had undergone splenectomy (37 cases) were compared with records of dogs that had undergone other abdominal surgery (43 cases). Records of dogs that presented for non-elective gastropexy (33 cases) were compared with records of dogs presented to the hospital for unrelated reasons (39 cases). Survival following splenectomy and development of GDV in the first 12 months following surgery were retrieved from the clinical records and by questionnaire-based canvassing of the referring clinician. The incidence of GDV following splenectomy was established and the association between a current episode of GDV and previous splenectomy was assessed. There was no evidence that splenectomy was associated with an increased incidence of subsequent GDV (P=0.469). No association between a current episode of GDV and previous splenectomy was found. Splenectomy is not associated with an increase in the incidence of GDV.

BACKGROUND For patients with esophagogastric varices secondary to portal hypertension due to liver cirrhosis, portosystemic shunts and devascularization have become the most commonly used treatment methods. We have developed a novel surgical approach for the treatment of patients with cirrhotic portal hypertension, selective decongestive devascularization, and shunt of the gastrosplenic region (SDDS-GSR). This aim of this study was to compare the efficacy and safety of SDDS-GSR with splenectomy with pericardial devascularization (SPD). MATERIAL AND METHODS A retrospective study was undertaken between 2006 and 2013 and included 110 patients with cirrhotic portal hypertension, 34 of whom underwent SDDS-GSR; 76 patients underwent SPD. Kaplan-Meier analysis was used to evaluate clinical outcomes, mortality, the incidence of re-bleeding, encephalopathy, and portal venous system thrombosis (PVST). RESULTS Postoperatively portal venous pressure decreased by 20% in both groups. The long-term incidence of re-bleeding and PVST was significantly lower in the SDDS-GSR group compared with the SPD group (P=0.018 and P=0.039, respectively). CONCLUSIONS This preliminary retrospective study has shown that SDDS-GSR was an effective treatment for patients with esophagogastric varices secondary to portal hypertension that may be used as a first-line treatment to prevent variceal bleeding and lower the incidence of PVST.

Spleen hydatidosis treated by hemi-splenectomy: A low-morbidity, cost-effective management by a recently improved surgical technique.

2015-08-01

Splenic hydatidosis is a rare condition and is usually managed by total splenectomy, which is associated to various complications, including overwhelming post-splenectomy sepsis and thrombosis. Probably due to supposed technical difficulties, the partial splenectomy is rarely performed being often unknown to physicians, infectious disease specialists and surgeons. Demographic, clinical and surgical data were collected of four consecutive patients undergoing partial (or hemi-) splenectomy using an original, recently improved technique as a treatment for polar splenic hydatid cyst. The procedure implies a selective vascular ligation, a mechanical stapler-assisted section and haemostatic agents (Surgicel(®)) application on the cutting surface. Three patients were treated by laparotomy (including one affected by both liver and spleen localizations) whereas the last one was approached laparoscopically. Partial splenectomy operative time reached 74 min (range: 60-94 min) and blood loss was 8 ml (range: 5-10 ml). Hospital stay was 5.6 days (range: 5-7 days). At a mean follow-up of 20 months (range: 12-36 months), outcomes were uneventful. Partial splenectomy for hydatidosis is effective and safe. Physicians and surgeons should be aware of such an easy-to-catch option when dealing with benign splenic conditions, such as parasitic cysts. Cost-effectiveness, low morbidity and the possible prevention of splenectomy-related infectious complications should plead in favor of this technique in developing countries, where hydatidosis is endemic and post-splenectomy drugs and vaccines may be lacking.

Remodeling of the liver following splenectomy may simulate hypertrophy of an accessory spleen on sulfur colloid scans. Two patients are reported. In one case splenic simulation is attributed to unusual hepatic scarring confirmed at autopsy. In the second the unusual configuration appears to have been caused by molding of the liver. The clinician should be aware of possible splenic simulation in postsplenectomy patients suspected of hypersplenism

Pinky M Thapar

2016-01-01

Full Text Available Laparoscopic splenectomy is a gold standard for management of planned benign splenic pathologies. Spontaneous rupture of the spleen (SRS leading to acute abdomen occurs in only 1% of all splenic ruptures. Laparoscopic splenectomy in traumatic and atraumatic rupture due to intra-splenic pathology is reported. We present the first reported case of laparoscopic splenectomy in a 23-year-old male who presented with hemoperitoneum due to idiopathic or SRS. The procedure was safely accomplished with slight modified technique and minimum usage of advanced gadgets.

We conducted a systematic review and meta-analysis to compare the clinical outcomes between laparoscopic splenectomy and the traditional open splenectomy in children. Literature searches were conducted to identify studies having compared the laparoscopic splenectomy (LS) and open splenectomy (OS) for children. Parameters such as operative time, blood loss, length of postoperative stay, the removal of accessory spleens and postoperative complications including postoperative high fever, acute chest syndrome (ACS), and ileus were pooled and compared by meta-analysis. Among the 922 pediatric participants included in the 10 studies, 508 had received LS and 414 OS. There were shorter length of hospital stays, less blood loss, and longer operative times with the LS approach compared with OS. However, no significant difference was found between LS and OS in the secondary outcome, such as the removal of accessory spleens or postoperative complications including postoperative high fever, ACS, and ileus. LS is a feasible, safe, and effective surgical procedure alternative to OS for pediatric patients. Compared with OS, LS has the advantage of shorter hospital stay and less blood loss. Besides, total postoperative complications may be slightly lower in LS. We conclude that LS should be considered an acceptable option for children.

Effectiveness of splenectomy for advanced gastric cancers occupying the upper and/or the middle third of the stomach is still in debate. The aim of the present study is to elucidate the impact of splenectomy on patient survival by investigating the pathological characteristics and prognostic significance of splenic hilar lymph node metastasis. Clinicopathologic and prognostic data of 265 patients with gastric cancer in the upper and/or the middle third of the stomach who underwent the operation of en bloc resection of primary cancer and D2/D3 lymphadenectomy combined with splenectomy were retrospectively reviewed. Multivariate analysis revealed pT category, pN category, and distant lymph node metastasis independently correlated with the presence of splenic hilar lymph node metastasis. Prognoses of patients with positive splenic hilar lymph nodes were significantly poorer than that of patients with negative splenic hilar lymph nodes for the entire study population and for those who underwent R0 resection, but not for those who underwent R1-2 resection. There was no significant difference in survival between patients who underwent R0 resection with positive splenic hilar lymph nodes and those who underwent R1-2 resection. Splenic hilar lymph node metastasis was one of independent indicators predicting worse prognosis and the presence of distant metastasis after surgery. Subset analysis according to the TNM stage revealed there were significant differences in survival between patients with and without splenic hilar lymph node metastasis. Splenic hilar lymph node metastasis should be considered as one of incurable factors. Consequently, the efficiency of splenectomy aiming at prolonging survival for patients with high risk of splenic hilar lymph nodes metastasis should be questioned, although resection of invasive organs form gastric cancers has been recommended if R0 surgery could be achieved.

1981-01-01

51 Cr-platelet kinetics study was performed in 197 patients with chronic ITP after corticosteroid therapy had failed to induce a long lasting remission. The incidence of splenic, spleno-hepatic, hepatic and diffuse platelet sequestration site was 58%, 17%, 6% and 19%, respectively. Splenic and spleno-hepatic sequestration sites were more frequent in patients less than 30 years old and in patients with a platelet count lower than 50 x 10 9 /l. 111 patients were splenectomized shortly after the study. Normalization of the platelet count was obtained more frequently in patients with splenic and spleno-hepatic sequestration than in the others. Labelled platelet sequestration site was the best predictor of the outcome of splenectomy. Platelet kinetics is a non-invasive investigation that should be performed early after the diagnosis of chronic ITP in all patients eligible for splenectomy. (author)

Aspartate transaminase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) are well known as representative indirect serum biomarkers related to liver fibrosis. The usefulness of these markers for the diagnosis of liver fibrosis after liver transplantation (LT) in hepatitis C virus (HCV)-infected patients and the influence of splenectomy were investigated. From June 2003 to May 2014, 31 HCV-infected patients who underwent LT and postoperative follow-up liver biopsies were included in this study. The association between liver fibrosis and serum biomarkers and the influence of splenectomy on APRI and FIB-4 were also investigated. A total of 195 biopsy specimens were collected, and liver fibrosis was identified as: F0, 59.7%; F1, 34.1%; and F2, 6.3%. Both APRI and FIB-4 were significantly higher in patients who showed F1 and F2 in liver biopsy specimen than F0 (P values, .009 and .022, respectively); sensitivity and specificity of APRI were, respectively, 63.4% and 66.7%, and those of FIB-4 were 57.7% and 69.6%. In 11 patients (35.5%) who underwent splenectomy at the time of LT, the cutoff values for APRI and FIB-4 were 0.61 and 1.41, which were significantly lower than the corresponding values (1.00 and 3.64) of patients without splenectomy. APRI and FIB-4 could effectively estimate liver fibrosis after LT for HCV-related liver disease. For LT patients with splenectomy, APRI and FIB-4 were also useful to estimate liver fibrosis, but the standard values should be adjusted lower than those for patients without splenectomy.

Nonoperative management (NOM) for blunt splenic injury (BSI) is well-established. Angiography (ANGIO) has been shown to improve success rates with NOM. Protocols for NOM are not standardized and vary widely between centers. We hypothesized that trauma centers that performed ANGIO at a greater rate would demonstrate decreased rates of splenectomy compared with trauma centers that used ANGIO less frequently. A large, multicenter, statewide database (Pennsylvania Trauma Systems Foundation) from 2007 to 2011 was used to generate the study cohort of patients with BSI (age ≥ 13). The cohort was divided into 2 populations based on admission to centers with high (≥13%) or low (Splenectomy rates were then compared between the 2 groups, and multivariable logistic regression for predictors of splenectomy (failed NOM) were also performed. The overall rate of splenectomy in the entire cohort was 21.0% (1,120 of 5,333 BSI patients). The high ANGIO group had a lesser rate of splenectoy compared with the low ANGIO group (19% vs 24%; P splenectomy compared with low ANGIO centers (odds ratio, 0.68; 95% CI 0.58-0.80; P splenectomy rates compared with centers with lesser rate of ANGIO. Inclusion of angiographic protocols for NOM of BSI should be considered strongly. Copyright © 2015 Elsevier Inc. All rights reserved.

Encouraging progress has been made in application of splenectomy in the treatment of relapsed hemophagocytic lymphohistiocytosis (HLH) of unknown cause. The aim was to determine the roles of lymphocyte subpopulations and inflammatory cytokines in splenectomy. We retrospectively analyzed changes in lymphocyte subpopulations and levels of inflammatory cytokines at different time-points before and after splenectomy in the patients with relapsed HLH of unknown cause, as well as the correlations between these changes and the disease prognosis. During the period from June 2006 to June 2016, we enrolled 107 patients with relapsed HLH of unknown cause, of whom 29 were treated with splenectomy. Among the 29 patients, 7 cases were non-Hodgkin lymphomas based on spleen pathology, 1 case withdrew and the remaining 21 non-lymphoma cases were available for analysis. Results showed a significant increase in both percentage of CD16 + CD56 + NK cells (P = 0.003) and NK cell activity (P = 0.028) at 24 wk after splenectomy compared to their baseline pre-surgery levels. We also examined seven patients for the changes in cytokine levels before and after splenectomy and found that IL-21 and IL-1α decreased at 4 wk after splenectomy (P splenectomy had significantly longer survival (P = 0.001) compared to the 24 patients with relapsed HLH of unknown cause who were also determined as NR but not treated by splenectomy. Splenectomy can improve clinical symptoms and survival of patients with relapsed HLH of unknown cause. The mechanism is likely related to the changes in percent NK cells and cytokines (IL-21 and IL-1α) after surgery.

Haematological and biochemical characteristics of the splenic effluent blood in schistosomal patients undergoing splenectomy

Directory of Open Access Journals (Sweden)

Andy Petroianu

Full Text Available OBJECTIVE: To assess hematological and biochemical features of splenic effluent blood and their influence on the rise of hematological values after splenectomy. METHODS: we studied 20 patients undergoing surgical treatment for schistosomatic portal hypertension. We collected blood samples for CBC, coagulation, bilirubin and albumin in the splenic vein (perioperative and peripheral blood (immediately pre and postoperative periods. RESULTS: the splenic blood showed higher values of red blood cells, hemoglobin, hematocrit, platelet count, total leukocytes, neutrophils, lymphocytes, monocytes, eosinophils and basophils, as well as reduction of laboratory coagulation parameters in relation to peripheral blood collected preoperatively. In the postoperative peripheral blood there was an increase in the overall leukocytes and in their neutrophil component, and decreased levels of basophils, eosinophils and lymphocytes. The other postoperative variables of complete blood count and coagulation tests were not different compared with the splenic blood. The albumin values were lower postoperatively when compared to preoperative and splenic blood. There were higher values of direct bilirubin in the postoperative period when compared with the preoperative and splenic blood. Postoperative indirect bilirubin was lower compared to its value in the splenic blood. CONCLUSION: hematological and biochemical values of splenic effluent blood are higher than those found in peripheral blood in the presence of schistosomal splenomegaly. However, the splenic blood effluent is not sufficient to raise the blood levels found after splenectomy.

Laparoscopic splenectomy has been proposed to be the standard therapy for adult patients with medically refractory immune thrombocytopenia (ITP). However, due to inconsistent definitions of response, variable rates of long term response have been reported. Furthermore, new medical treatment options are currently challenging the role of splenectomy. The aims of this study were to (1) analyze long term response after splenectomy according to recently defined consensus criteria, (2) identify possible predictive response factors. A case series of 72 consecutive patients with ITP undergoing laparoscopic splenectomy was retrospectively studied using univariate and multivariate analysis as well as logrank tests. Median follow-up was 32 (2-110) months. Mortality was 0% and morbidity was 8.2%. Response to splenectomy was achieved in of 63/72 patients (87.5%). Loss of response occurred in 19/63 (30.2%) in median after 3 (range 2-42) months. Preoperative platelet counts after boosting with steroids and immunoglobulins as well as the postoperative rise in platelet counts were statistically significant factors for response upon both univariate and multivariate analysis, whereas age, gender, body mass index, ASA classification, disease duration, accessory spleens, splenic weight, conversion to open surgery, or perioperative complications were not. Patients with a postoperative rise in platelet counts >150,000/μL had a significant better chance on stable long term response than those with a smaller increment (P splenectomy is an effective and safe treatment option in order to obtain stable long term response in patients with ITP. Perioperative platelet counts are predictive factors of long term response. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Single-access laparoscopic splenectomy can offer patients some advantages. It has many difficulties, such as instrument clashing, lack of triangulation, odd angles and lack of space. The Da Vinci Single-Site® robotic surgery platform could decrease these difficulties. We present a case of single-access robotic splenectomy using this device. A 37 year-old female with idiopathic thrombocytopenic purpura was operated on with a single-site approach, using the Da Vinci Single-Site robotic surgery device. The procedure was successfully completed in 140 min. No intraoperative and postoperative complications occurred. The patient was discharged from hospital on day 3. Single-access robotic splenectomy seems to be feasible and safe using the new robotic single-access platform, which seems to overcome certain limits of previous robotic or conventional single-access laparoscopy. We think that additional studies should also be performed to explore the real cost-effectiveness of the platform. Copyright © 2013 John Wiley & Sons, Ltd.

Remodeling of the liver following splenectomy may simulate hypertrophy of an accessory spleen on sulphur colloid scans. There are but a few reports about the persistent splenic activity as a prominent finding during the post-splenectomy period. Splenic simulation may be attributed to the unusual hepatic lobe displacement, as in this case. The clinician should be aware of possible splenic simulation in the post-splenectomy period, if hypersplenism is suspected

Objective This study aimed to investigate the association between splenectomy and empyema in Taiwan. Methods A population-based cohort study was conducted using the hospitalisation dataset of the Taiwan National Health Insurance Program. A total of 13 193 subjects aged 20–84 years who were newly diagnosed with splenectomy from 2000 to 2010 were enrolled in the splenectomy group and 52 464 randomly selected subjects without splenectomy were enrolled in the non-splenectomy group. Both groups were matched by sex, age, comorbidities and the index year of undergoing splenectomy. The incidence of empyema at the end of 2011 was calculated. A multivariable Cox proportional hazards regression model was used to estimate the HR with 95% CI of empyema associated with splenectomy and other comorbidities. Results The overall incidence rate of empyema was 2.56-fold higher in the splenectomy group than in the non-splenectomy group (8.85 vs 3.46 per 1000 person-years). The Kaplan-Meier analysis revealed a higher cumulative incidence of empyema in the splenectomy group than in the non-splenectomy group (6.99% vs 3.37% at the end of follow-up). After adjusting for confounding variables, the adjusted HR of empyema was 2.89 for the splenectomy group compared with that for the non-splenectomy group. Further analysis revealed that HR of empyema was 4.52 for subjects with splenectomy alone. Conclusion The incidence rate ratio between the splenectomy and non-splenectomy groups reduced from 2.87 in the first 5 years of follow-up to 1.73 in the period following the 5 years. Future studies are required to confirm whether a longer follow-up period would further reduce this average ratio. For the splenectomy group, the overall HR of developing empyema was 2.89 after adjusting for age, sex and comorbidities, which was identified from previous literature. The risk of empyema following splenectomy remains high despite the absence of these comorbidities. PMID:28947439

2013-01-01

Background The spleen is an active lymphoid organ. The effect of splenectomy on the immune response remains unclear. This study investigated whether splenectomy can induce immune tolerance and has a beneficial role in cardiac allograft. Methods Wistar rats were used for heart donors. The Sprague–Dawley (SD) rats designated as the recipients of heart transplantation (HT) were randomly assigned into four groups: sham, splenectomy, HT, splenectomy + HT. The survival of transplanted hearts was assessed by daily checking of abdominal palpation. At various time points after transplantation, the transplanted hearts were collected and histologically examined; the level of CD4+CD25+ T regulatory lymphocytes (Tregs) and rate of lymphocyte apoptosis (annexin-v+ PI+ cells) in the blood were analyzed by using flow cytometric method. Results 1) Splenectomy significantly prolonged the mean survival time of heart allografts (7 ± 1.1 days and 27 ± 1.5 days for HT and splenectomy + HT, respectively; n = 12-14/group, HT vs. splenectomy + HT, p Splenectomy delayed pathological changes (inflammatory cell infiltration, myocardial damage) of the transplanted hearts in splenectomy + HT rats; 3) The level of CD4+CD25+ Tregs in the blood of splenectomized rats was significantly increased within 7 days (2.4 ± 0.5%, 4.9 ± 1.3% and 5.3 ± 1.0% for sham, splenectomy and splenectomy + HT, respectively; n = 15/group, sham vs. splenectomy or splenectomy + HT, p splenectomy surgery and gradually decreased to baseline level; 4) Splenectomy increased the rate of lymphocyte apoptosis (day 7: 0.3 ± 0.05%, 3.9 ± 0.9% and 4.1 ± 0.9% for sham, splenectomy and splenectomy + HT, respectively; n = 15/group, sham vs. splenectomy or splenectomy + HT, p Splenectomy inhibits the development of pathology and prolongs the survival time of cardiac allograft. The responsible mechanism is associated with induction of immune

The advent of new energy sources for hemostasis has greatly facilitated advanced laparoscopic procedures. We describe a straightforward technique of laparoscopic splenectomy (LS) accomplished using the THUNDERBEAT™ system (TS) (Olympus Medical Systems Corp., Tokyo, Japan) as the sole means of tissue dissection and hemostasis in two patients aged 19 and 6 years, respectively. The specimens were removed intact via a Pfannenstiel incision. Total operative time was 165 and 150 min, and length of hospital stay was three and 4 d, respectively. The TS is an appealing and reliable alternative to currently available energy devices, allowing fast dissection and secure hemostasis during laparoscopic splenectomy.

To study the immunological effects of splenic autotransplantation, forty patients with splenic trauma were divided into two groups equally. One group underwent splenic autotransplantation and another underwent splenectomy. Control group included ten cases. Splenic autotransplantation and splenectomy group were compared with the control group. In the group of splenic autotransplantation, CD3 + , CD4 + , CD8 + , CD4 + /CD8 + dropped and sIL-2R, TNF rose after a week of operation. Then CD3 + , CD4 + , CD8 + , CD4 + /CD8 + rose and sIL-2R, TNF dropped three months later. In the group of splenectomy, CD 3+ , CD4 + , CD8 + and CD4 + /CD8 + dropped persistently, while sIL-2R and TNF rose postoperatively. Result showed splenic autotransplantation can help body to maintain T-cells level and improve the anti-infective ability

With the better understanding of the importance of the spleen as a primary organ of the human immune system, there has been an increased interest in performing the partial splenectomy for a number of indications such as nonparasitic cysts, benign tumors, staging of lymphomas, etc. Moreover, laparoscopic partial splenectomy has been gaining more interest as the recommended approach for benign splenic disorders to preserve the splenic function with very low recurrence rates. Meanwhile, many surgeons have attempted to reduce the number and size of the ports in laparoscopic surgery with the aim of inducing less parietal trauma and fewer scars. One of these efforts is single-port laparoscopic surgery, which is a rapidly evolving field all over the world. Here, we describe a feasible method of single-port laparoscopic partial splenectomy for treating a benign splenic cyst that was located in the upper medial aspect of the spleen.

Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

We assessed splenic activity after splenectomy by interference phase microscopical examination of circulating red cells. Normal eusplenic children had a low number (<1%) of red cells with surface indentations or pits. About 20% of red cells of children who had electively been subjected to splenectomy for hematologic indications were pitted. Thirteen of 22 children who had had emergency splenectomy because of traumatic injury had a low percentage of pitted red cells, suggesting a return of splenic function. In five of these children a /sup 99m/Tc sulfur colloid scan demonstrated multiple nodules of recurrent splenic tissue. In contrast to the prevailing opinion that splenosis is rare, we have found it to be a frequent occurrence. Return of splenic function may, in part, account for the low frequency with which overwhelming bacterial sepsis and meningitis have been documented after splenectomy for traumatic indications

Massive splenic infarction (MSI) is a very rare condition. Few reports of splenic infarction of various etiologies including hematological and non-hematological causes have been published. On the other hand, MSI in patients with sickle cell anemia (SCA) is extremely rare. This report describes our experience with 15 children with SCA and MSI outlining aspects of presentation, diagnosis and management. The records of all children with MSI were retrospectively reviewed for age at diagnosis, sex, clinical features, precipitating factors, investigations, management and outcome. 15 children (11 M: 4 F) with SCA were treated for MSI. Their mean age was 10.9 years (6-17 years). All presented with severe left upper quadrant abdominal pain. In nine, this was associated with nausea and vomiting. Three were febrile and all had a tender splenomegaly. Their mean hemoglobin was 8.2 g/dl (5.7-11.3 g/dl), mean WBC was 10.97 × 10(3) mm(-3) (3.6 × 10(3)-22.3 × 10(3) mm(-3)) and mean platelet count was 263.3 × 10(3) mm(-3) (40 × 10(3)-660 × 10(3) mm(-3)). In seven, there was a precipitating cause including high altitude in two, acute chest syndrome in two, septicemia in two and severe vasooclusive crisis in one. Abdominal ultrasound and CT scan confirmed the diagnosis of MSI which involved more than half of the spleen in 12 and whole spleen in 3. All were treated with IV fluids, analgesia and blood transfusion where appropriate. Eleven had splenectomy because of persistent abdominal pain, three developed splenic abscess and underwent splenectomy and one settled on conservative treatment. Histology confirmed the diagnosis of splenic infarction in 11 and infarction with abscess in the remaining 3. MSI is extremely rare in children with SCA. It can develop spontaneously or precipitated by other factors namely high altitude, acute chest syndrome and severe stress. Most reported cases of splenic infarction are small in size, focal and can be treated conservatively. MSI, on the other

The effects of total lymphoid irradiation, cyclosporine and splenectomy alone and in combination have been studied in liver transplants from the LVG hamster to the LEW rat. Neither CsA alone, splenectomy alone, nor TLI alone prolonged graft survival. CsA/splenectomy and TLI/CsA produced significant prolongation of graft survival. TLI/CsA/splenectomy prolonged graft survival by over sixfold compared with controls. While CsA alone was ineffective in reducing lymphocytotoxic antidonor antibody, splenectomy alone or CsA/splenectomy did significantly suppress production of antibody. Only very low levels of antibody could be detected in animals treated with TLI/CsA/splenectomy. TLI/CsA/splenectomy has an immunosuppressive effect sufficient to significantly prolong liver graft survival in the LVG hamster to LEW rat combination and may represent a promising treatment protocol in experimental cross-species transplantation

Splenectomy in cirrhotic patients has been reported to improve liver function; however the underlying mechanism remains obscure. In the present study, we investigated the mechanism using a murine model, which represents well the compensated liver cirrhosis. C57BL/6 male mice were allowed to drink water including thioacetamide (TAA: 300 mg/L) ad libitum for 32 weeks. After splenectomy at 32 weeks, mice were sacrificed on days one, seven, and 28, respectively, while TAA-administration was continued. Perioperative changes in peripheral blood and liver tissues were analyzed. TAA treatment of mice for 32 weeks reproducibly achieved advanced liver fibrosis with splenomegaly, thrombocytopenia, and leukocytopenia. After splenectomy, liver fibrosis was attenuated, and macrophages/monocytes were significantly increased in peripheral blood, as well as in the liver. Progenitor-like cells expressing CK-19, EpCAM, or CD-133 appeared in the liver after TAA treatment, and gradually disappeared after splenectomy. Macrophages/monocytes accumulated in the liver, most of which were negative for Ly-6C, were adjacent to the hepatic progenitor-like cells, and quantitative RT-PCR indicated increased canonical Wnt and decreased Notch signals. As a result, a significant amount of β-catenin accumulated in the progenitor-like cells. Moreover, relatively small Ki67-positive hepatic cells were significantly increased. Protein expression of MMP-9, to which Ly-6G-positive neutrophils contributed, was also increased in the liver after splenectomy. The hepatic accumulation of macrophages/monocytes, most of which are Ly-6C(lo), the reduction of fibrosis, and the gradual disappearance of hepatic progenitor-like cells possibly play significant roles in the tissue remodeling process in cirrhotic livers after splenectomy.

Many studies have been conducted on splenic thermal ablation for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism. In this article, we review the evolution and current status of radiofrequency and microwave ablation in the treatment of spleen diseases. All publications from 1990 to 2011 on radiofrequency and microwave ablation for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism were retrieved by searching PubMed. Thermal ablation in the spleen for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism can preserve part of the spleen and maintain splenic immunologic function. Thermal ablation for assisting hemostasis in partial splenectomy minimizes blood loss during operation. Thermal ablation for spleen trauma reduces the number of splenectomy and the amount of blood transfusion. Thermal ablation for splenic metastasis is minimally invasive and can be done under the guidance of an ultrasound, which helps shorten the recovery time. Thermal ablation for hypersplenism increases platelet (PLT) and white blood cell (WBC) counts and improves liver function. It also helps to maintain splenic immunologic function and even improves splenic immunologic function in the short-term. In conclusion, thermal ablative approaches are promising for partial splenectomy hemostasis, spleen trauma, splenic metastasis and hypersplenism. In order to improve therapeutic effects, directions for future studies may include standardized therapeutic indications, prolonged observation periods and enlarged sample sizes.

Objective: To analyze the recent postoperative and long-term postoperative complications of open-splenectomy and disconnection in patients with portal hypertension. Methods: There were 1 118 cases with portal hypertension who underwent open splenectomy and azygoportal disconnection from April 2010 to September 2015 at Department of Surgery, People's Liberation Army 302 Hospital. Retrospective case investigation and telephone follow-up were conducted in October 2016. All patients had history of upper gastrointestinal bleeding before operation. Short-term complications after surgery were recorded including secondary laparotomy of postoperative abdominal hemostasis, severe infection, intake disorders, liver insufficiency, postoperative portal vein thrombosis and perioperative mortality. Long-term data including postoperative upper gastrointestinal rebleeding, postoperative survival rate and incidence of postoperative malignancy were recorded, too. GraphPad Prism 5 software for data survival analysis and charting. Results: Postoperative short-term complications in 1 118 patients included secondary laparotomy of postoperative abdominal hemostasis(1.8%, 21/1 118), severe infection(2.9%, 32/1 118), intake disorders(1.0%, 11/1 118), liver dysfunction (1.6%, 18/1 118), postoperative portal vein thrombosis(47.1%, 526/1 118)and perioperative mortality(0.5%, 5/1 118). After phone call following-up, 942 patients' long-term data were completed including 1, 3, 5 years postoperative upper gastrointestinal rebleeding rate(4.4%, 12.1%, 17.2%), 1, 3, 5-year postoperative survival rate(97.0%, 93.5%, 90.3%); the incidence of postoperative malignant tumors in 1, 3 and 5 years were 1.7%, 4.4% and 6.2%. Conclusions: Reasonable choosing of surgical indications and timing, proper performing the surgery process, effective conducting perioperative management of portal hypertension are directly related to the patient's short-term prognosis after portal hypertension.

Full Text Available Background: Missed or inappropriately-treated splenic injury is a significant cause of preventable trauma-related death. Physical examination and abdominal ultrasonography are essential tools for early diagnosis of splenic injury. However, some injuries may not be accurately diagnosed by ultrasonography at initial evaluation. Aim: The aim of this study was to audit indications for splenectomy at the University College Hospital, Ibadan and to compare the intra-operative findings in trauma-related cases with the sonographic findings. Materials and Methods: We retrospectively reviewed all adult (12 years and older patients′ records who had splenectomy between July 2003 and June 2010. The data extracted included patient demographics and indications for splenectomy. In trauma cases, the mode of injury and vital signs at presentation, sonographic findings, and operation findings were recorded. The intervals between injury and sonography and duration to surgery were also noted respectively. Results: Eighty-four patients were reviewed in the 7-year review period. The male to female ratio was approximately 2:1. The ages ranged from 14 to 76 years with a peak incidence in the third decade. Elective indications for splenectomy were 14 (16.6%, while 70 (83.3% were emergency cases. Forty-four of the trauma-related patients had pre-operative abdominal ultrasound, of which 31 (70% was reported as sonographically normal prior to surgery, while the rest of the trauma-related cases were considered too ill for ultrasonography. Conclusion: Potentially significant injuries may be missed with screening sonography. For this reason, a physician must maintain a high index of suspicion and consider the patient′s clinical status or an alternative imaging modality in excluding a diagnosis of splenic injury.

Effects of radiochemotherapy and splenectomy on cellular immunity in long-term survivors of Hodgkin's disease and non-Hodgkin's lymphoma

Thirty-six patients treated for Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) who had been in complete remission and off all therapy for greater than two years were examined for evidence of immunosuppression. All patients were found to have marked depression of their lymphocyte blastogenic response to phytohemagglutinin (PHA) and of their skin test responses. No abnormalities of serum protein or immunoglobulins were found. T cells were significantly lower than normal in patients who had had Hodgkin's disease, but not in those who had had NHL. B cells, on the other hand, were significantly elevated in both groups. Splenectomy elevated the total lymphocyte count, while those who had not had a splenectomy had lower than normal lymphocyte counts. B cells were elevated while T cells tended to be lower in both splenectomy and nonsplenectomy groups, though only in the nonsplenectomized patients did this reach statistical significance. The PHA response tended to be higher in patients with less advanced disease and less extensive treatment than in those with more advanced disease and more extensive treatment, although there was no statistically significant difference. Skin test response though, was shown to correlate well with both stage of disease at diagnosis and extent of treatment

To objectively demonstrate the gain in blood volume and blood components following early ligation of splenic artery during splenectomy and splenorenal shunts in children with extra hepatic portal venous obstruction (EHPVO). Twenty-eight children (20 males and 8 females, mean age: 9.9 (+/-3.2) years) with EHPVO and hypersplenism were recruited. We followed a protocol of systematically locating and ligating the splenic artery first, followed by a 30-minute waiting period to allow the massive spleen to decongest via the splenic vein and venous collaterals and then completing the splenectomy by standard procedure. No intravenous fluid was administered during this 30-minute period. Blood samples were drawn just prior to splenic artery ligation and soon after splenectomy for the estimation of hematological and biochemical parameters. We noticed a highly significant increase in the hemoglobin, hematocrit, leukocyte, platelet, and RBC counts by early ligation of the splenic artery (p platelet count was equivalent to a platelet transfusion of atleast 4 units of platelet concentrates in an adult. There is a positive correlation between the splenic weight and the platelet gain (p= 0.0568) and the splenic volume on preoperative imaging and the platelet gain (p= 0.0251). Early ligation of the splenic artery during splenectomy results in passive splenic decongestion and thereby a significant gain in blood components. This protocol appears to be a feasible blood conservation method to avoid blood transfusions in this group of hypersplenic EHPVO patients.

Traumatic injuries to the distal pancreas are infrequent. Universally accepted recommendations about the need for routine splenectomy with distal pancreatectomy do not exist. The aims of this study were to compare outcomes after distal pancreatectomy and splenectomy versus spleen-preserving distal pancreatectomy, and to define the appropriate patient population for splenic preservation. All patients who underwent distal pancreatectomy (January 1, 2007, to December 31, 2014) were identified from the National Trauma Data Bank. Patients with concomitant splenic injury and those who underwent partial splenectomy were excluded. Demographics, clinical data, procedures, and outcomes were collected. Study groups were defined by surgical procedure: distal pancreatectomy and splenectomy versus spleen-preserving distal pancreatectomy. Baseline characteristics between groups were compared with univariate analysis. Multivariate analysis was performed with logistic and linear regression to examine differences in outcomes. Over the 8-year study period, 2,223 patients underwent distal pancreatectomy. After excluding 1,381 patients with concomitant splenic injury (62%) and 8 (pancreatectomy and splenectomy, those who underwent spleen-preserving distal pancreatectomy were younger (p pancreatectomy (p = 0.017). Complications, mortality, and intensive care unit LOS were not significantly different. In young patients after blunt trauma who are not severely injured, a spleen-preserving distal pancreatectomy should be considered to allow for conservation of splenic function and a shorter hospital LOS. In all other patients, the surgeon should not hesitate to remove the spleen with the distal pancreas. Therapy, level IV.

Delayed splenic hemorrhage after nonoperative management (NOM) of blunt splenic injury (BSI) is a feared complication, particularly in the outpatient setting. Significant resources, including angiography (ANGIO), are used in an effort to prevent delayed splenectomy (DS). No prospective, long-term data exist to determine the actual risk of splenectomy. The purposes of this trial were to ascertain the 180-day risk of splenectomy after 24 hours of NOM of BSI and to determine factors related to splenectomy. Eleven Level I trauma centers participated in this prospective observational study. Adult patients achieving 24 hours of NOM of their BSI were eligible. Patients were followed up for 180 days. Demographic, physiologic, radiographic, injury-related information, and spleen-related interventions were recorded. Bivariate and multivariable analyses were used to determine factors associated with DS. A total of 383 patients were enrolled. Twelve patients (3.1%) underwent in-hospital splenectomy between 24 hours and 9 days after injury. Of 366 discharged with a spleen, 1 (0.27%) required readmission for DS on postinjury Day 12. No Grade I injuries experienced DS. The splenectomy rate after 24 hours of NOM was 1.5 per 1,000 patient-days. Only extravasation from the spleen at time of admission (ADMIT-BLUSH) was associated with splenectomy (odds ratio, 3.6; 95% confidence interval, 1.4-12.4). Of patients with ADMIT-BLUSH (n = 49), 17 (34.7%) did not have ANGIO with embolization (EMBO), and 2 of those (11.8%) underwent splenectomy; 32 (65.3%) underwent ANGIO with EMBO, and 2 of those (6.3%, p = 0.6020 compared with no ANGIO with EMBO) required splenectomy. Splenectomy after 24 hours of NOM is rare. After the initial 24 hours, no additional interventions are warranted for patients with Grade I injuries. For Grades II to V, close observation as an inpatient or outpatient is indicated for 10 days to 14 days. ADMIT-BLUSH is a strong predictor of DS and should lead to close

Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

Three-dimensional printing technology is rapidly changing the way we produce all sort of objects, having also included medical applications. We embarked in a pilot study to assess the value of patient-specific 3-D physical manufacturing of spleno-pancreatic anatomy in helping during patient's counseling and for preoperative planning. Twelve patients scheduled for a laparoscopic splenectomy underwent contrast CT and subsequent post-processing to create virtual 3-D models of the target anatomy, and 3-D printing of the relative solid objects. The printing process, its cost and encountered problems were monitored and recorded. Patients were asked to rate the value of 3-D objects on a 1-5 scale in facilitating their understanding of the proposed procedure. Also 10 surgical residents were required to evaluate the perceived extra value of 3-D printing in the preoperative planning process. The post-processing analysis required an average of 2; 20 h was needed to physically print each model and 4 additional hours to finalize each object. The cost for the material employed for each object was around 300 euros. Ten patients gave a score of 5, two a score of 4. Six residents gave a score of 5, four a score of 4. Three-dimensional printing is helpful in understanding complex anatomy for educational purposes at all levels. Cost and working time to produce good quality objects are still considerable.

Objective The objective of the study was to investigate the association between splenectomy and acute pancreatitis. Methods We conducted a case-control study using the database of the Taiwan National Health Insurance Program. We included 7666 subjects aged 20–84 years with first-time acute pancreatitis during the period of 1998–2011 as cases and 30 664 randomly selected subjects without acute pancreatitis as controls. Both cases and controls were matched for sex, age, and index year of acute pancreatitis diagnosis. The association of acute pancreatitis with splenectomy was examined using a multivariable unconditional logistic regression model and reported as an odds ratio and its 95% confidence interval (CI). Results After adjustment for covariables, the adjusted odds ratio of acute pancreatitis was 2.90 for subjects with splenectomy (95% CI, 1.39–6.05) compared with subjects without splenectomy. Conclusions Splenectomy is associated with acute pancreatitis. Further studies are necessary to clarify the underlying mechanism. PMID:27087607

1996-01-01

The effect of splenectomy on reticuloendothelial system (RES) function was investigated by measurement of 99m Tc-phytate in the presence or absence of sepsis in rats, and plasma fibronectin (PFn) and hyaluronic acid (HA) concentrations were measured. The results were as follows: following splenectomy, particularly in the presence of sepsis, the intravascular clearance (T 1/2 ) delayed and HA increased, phagocytic index (K) and hepatic uptake and PFn decreased. These results suggest that splenectomy may not only have deleterious effects in terms of the host defence system, but may also cause RES depression due to the post splenectomy infection

Following blunt splenic injury, there is conflicting evidence regarding the natural history and appropriate management of patients with vascular injuries of the spleen such as pseudoaneurysms or blushes. The purpose of this study was to describe the current management and outcomes of patients with pseudoaneurysm or blush. Data were collected on adult (aged ≥18 years) patients with blunt splenic injury and a splenic vascular injury from 17 trauma centers. Demographic, physiologic, radiographic, and injury characteristics were gathered. Management and outcomes were collected. Univariate and multivariable analyses were used to determine factors associated with splenectomy. Two hundred patients with a vascular abnormality on computed tomography scan were enrolled. Of those, 14.5% were managed with early splenectomy. Of the remaining patients, 59% underwent angiography and embolization (ANGIO), and 26.5% were observed. Of those who underwent ANGIO, 5.9% had a repeat ANGIO, and 6.8% had splenectomy. Of those observed, 9.4% had a delayed ANGIO, and 7.6% underwent splenectomy. There were no statistically significant differences between those observed and those who underwent ANGIO. There were 111 computed tomography scans with splenic vascular injuries available for review by an expert trauma radiologist. The concordance between the original classification of the type of vascular abnormality and the expert radiologist's interpretation was 56.3%. Based on expert review, the presence of an actively bleeding vascular injury was associated with a 40.9% risk of splenectomy. This was significantly higher than those with a nonbleeding vascular injury. In this series, the vast majority of patients are managed with ANGIO and usually embolization, whereas splenectomy remains a rare event. However, patients with a bleeding vascular injury of the spleen are at high risk of nonoperative failure, no matter the strategy used for management. This group may warrant closer observation or

Splenectomy for people with thalassaemia major or intermedia.

Thalassaemia is a genetic disease of the haemoglobin protein in red blood cells. It is classified into thalassaemia minor, intermedia and major, depending on the severity of the disease and the genetic defect. Thalassaemia major and intermedia require frequent blood transfusions to compensate for the lack of well-functioning red blood cells, although this need is significantly less in thalassaemia intermedia.Damaged or defective red blood cells are normally eliminated in the spleen. In people with thalassaemia there is a large quantity of defective red blood cells which results in an enlarged hyperfunctioning spleen (splenomegaly). Removal of the spleen may thus prolong red blood cell survival by reducing the amount of red blood cells removed from circulation and may ultimately result in the reduced need for blood transfusions. To assess the efficacy and safety of splenectomy in people with beta-thalassaemia major or intermedia. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Review Group's Haemoglobinopathies Trials Register, compiled from searches of electronic databases and the handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews.Date of the most recent search: 25 April 2016. We included randomised controlled studies and quasi-randomised controlled studies of people of any age with thalassaemia major or intermedia, evaluating splenectomy in comparison to conservative treatment (transfusion therapy and iron chelation) or other forms of splenectomy compared to each other (laparoscopic, open, radio-frequency). Two authors independently selected and extracted data from the single included study using a customised data extraction form and assessed the risk of bias. One study, including 28 participants was included in the review; the results were described, primarily, in a narrative manner. The study assessed the feasibility of splenectomy using laparoscopy in comparison to open

Detection of splenosis and ectopic spleens with sup(99m)Tc-labelled heat damaged autologous erythrocytes in 90 splenectomized patients

Splenosis or ectopic spleens were determined in 22 of 45 patients splenectomized after either abdominal trauma or accidental lesions of the spleen during operation. The incidence of ectopic spleen in various groups of splenectomized patients has been investigated by a sensitive scanning method employing reinjection of sup(99m)Tc-labelled heat damaged autologous erythrocytes. In comparison 7 cases were found among 45 patients who underwent splenectomy for haematological reasons. The time span between the operation and a positive scan varied between 3 months and 11 years. None of the patients in the haematological group with reoccurrence of spleen tissue presented any signs of relapse of their primary disorder. The only patient with overwhelming infection was a girl in whom splemectomy was performed for hereditary spherocytosis. She recovered from the sepsis and her scan was negative. It is concluded that recurrence of spleen tissue is frequent after traumatic lesions of the spleen but rare after selective splenectomy for haematological reasons. This may account for the lesser tendency to overwhelming sepsis after post-traumatic splenectomy. (author)

Body-surface measurements were performed during {sup 51}Cr-platelet survival studies in patients with a normal or a reduced platelet life-span. As quantification of organ activity from surface recordings is hardly feasible, we tried to reach conclusions from the course of surface activity during platelet destruction. Continuous recording was applied during 30 or 50 min after platelet infusion, in order to avoid the problems raised by variations in counter positioning in spaced recordings. Surface activity was recorded over liver and spleen and/or heart independently by collimated Nal(Tl) crystals, and registered either by a rate-meter and recorder or by a 400-channel analyser. The exponential survival curve and reduced 2-h platelet recovery in patients with reduced platelet life-span suggest that in most cases a substantial destruction occurs in these first 50 min. Detection of platelet destruction in the spleen in this period is obscured, however, by the normal pooling of platelets in the spleen. Over the liver it is more easy to recognize platelet destruction because the rising course of activity differs distinctly from the normal , course. In all five patients with reduced platelet survival after splenectomy, hepatic platelet destruction was demonstrated. In 22 patients with reduced platelet survival and an intact spleen, hepatic platelet destruction was demonstrated in six. Hepatic platelet destruction was observed not only in patients with an extremely short platelet life-span, but also in patients with only moderately impaired platelet survival. The hypothesis that a failure from splenectomy can be predicted from a rising course of activity over the liver was tested in 11 patients. One of these had a failure from splenectomy in spite of a normal preoperative liver curve. Evidence is presented that in this case corticosteroid therapy had obscured hepatic platelet destruction. The results of operation in the other 10 patients (nine remissions and one failure

Full Text Available Aim: To objectively demonstrate the gain in blood volume and blood components following early ligation of splenic artery during splenectomy and splenorenal shunts in children with extra hepatic portal venous obstruction (EHPVO. Methods: Twenty-eight children (20 males and 8 females, mean age: 9.9 (±3.2 years with EHPVO and hypersplenism were recruited. We followed a protocol of systematically locating and ligating the splenic artery first, followed by a 30-minute waiting period to allow the massive spleen to decongest via the splenic vein and venous collaterals and then completing the splenectomy by standard procedure. No intravenous fluid was administered during this 30-minute period. Blood samples were drawn just prior to splenic artery ligation and soon after splenectomy for the estimation of hematological and biochemical parameters. Results: We noticed a highly significant increase in the hemoglobin, hematocrit, leukocyte, platelet, and RBC counts by early ligation of the splenic artery (p < 0.0004. The gain in hemoglobin and hematocrit was equivalent to a transfusion of atleast 100-150 ml of packed RBC. The increase in platelet count was equivalent to a platelet transfusion of atleast 4 units of platelet concentrates in an adult. There is a positive correlation between the splenic weight and the platelet gain (p= 0.0568 and the splenic volume on preoperative imaging and the platelet gain (p= 0.0251. Conclusion: Early ligation of the splenic artery during splenectomy results in passive splenic decongestion and thereby a significant gain in blood components. This protocol appears to be a feasible blood conservation method to avoid blood transfusions in this group of hypersplenic EHPVO patients.

The role of hepatic hemodynamic modulation in the development of "small-for-size" syndrome (SFSS) after extended hepatectomy (EH) or living-donor liver transplantation is still controversial. We have designed an experimental study to investigate the effect of hemodynamic parameters of the liver circulation on the development of SFSS after EH in a porcine model. Eighteen pigs were randomly divided into two groups: group A has received EH (75%-80%) without splenectomy, and group B with EH and simultaneous splenectomy was carried out. Portal hemodynamics, liver function tests, histologic findings, injury and survival rates were compared between groups A and B. The 7-d survival rate in the splenectomy group was significantly improved compared with group A (88.9% versus 44.4%, P splenectomy group were significantly lower than in group A immediately after splenectomy and postoperatively until the day of sacrifice. Histologic findings in group A clearly illustrate severe inflammation, bridging necrosis, ischemic cholangitis, and severe congestion, while in group B there were less serious histologic changes. Our experimental study indicates that perioperative portal modulation can successfully prevent the manifestation of SFSS after EH. Therefore, by focusing on "flow" rather than on "size," researchers may understand better the pathophysiology of this syndrome. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose. To investigate the preventive effect of resveratrol (RES) on the formation of portal vein system thrombosis (PVST) in a rat fibrosis model. Methods. A total of 64 male SD rats, weighing 200–300 g, were divided into five groups: Sham operation, Splenectomy I, Splenectomy II, RES, and low molecular weight heparin (LMWH), with the former two groups as nonfibrosis controls. Blood samples were subjected to biochemical assays. Platelet apoptosis was measured by flow cytometry. All rats were euthanized for PVST detection one week after operation. Results. No PVST occurred in nonfibrosis controls. Compared to Splenectomy II, the incidences of PVST in RES and LMWH groups were significantly decreased (both p Splenectomy II (all p splenectomy in cirrhotic rat. Regulation of platelet function and induction of platelet apoptosis might be the underlying mechanisms. PMID:27433290

Wistar rats submitted to isolated total splenectomy or total splenectomy combined with splenic autotransplantation were inoculated with {sup 99m}technetium-labeled Escherichia coli. Measurement of isotope uptake in the organs of the mononuclear phagocytic system showed a greater bacterial bloodstream clearance in rats with splenic autotransplantation. Although uptake of bacteria in the spleen was higher in the control group, the number of bacteria remaining in the bloodstream did not differ between groups. These results indicate that splenic autotransplantation preserves the phagocytic function of the spleen.

Autoradiography and various quantitations on lymphoid tissues have been used to evaluate the kinetics of small lymphocytes in normal (+/nu or +/+) and congenitally athymic nude (nu/nu) NMRI mice 1 month after splenectomy or sham-splenectomy. The results indicate that splenectomy causes depressed...... thymic activity and diminished numbers of T lymphocytes in peripheral lymphoid tissues. The total number of cells in these tissues as well as the blast cell activity, were within normal limits. Bone marrow lymphocyte numbers and kinetics as well as blood lymphocyte levels in splenectomized and sham......-splenectomized normal animals were comparable. Blood lymphocyte numbers were at normal levels in splenectomized nude mice, in spite of reduced numbers of bone marrow and thoracic duct lymphocytes. It is suggested that increased number of newly-formed lymphocytes, found in lymph nodes and blood of splenectomized mice...

Full Text Available Spleen is mysterious organ. It can be troublesome specimen for surgical pathologist due to discordance between patient’s clinical condition and perceived finding. The weight of spleen is about 150 grams and lies beneath 9th to 12th thoracic rib in healthy adult and between fundus of stomach & diaphragm. It composed of red pulp (76-79% and white pulp (5-20% which are separated by marginal zone. A total of 100 cases were studied at histopathology section of our laboratory during the period of January 2015 to December 2015. The specimens were received in 10% neutral buffer formalin with duly filled request form. All specimens were examined macroscopically. After routine processing the sections were stained with routine haematoxylin and eosin stain. The most common age group to be affected is 3rd decade (29%, next was 4th decade (23% with slightly male predominance. Male: female ratio is 1.3:1. Most common cause for splenectomy was portal hypertension (33% followed by trauma (15%. Most common microscopic finding is fibrocongestive splenomegaly (68% which is correlated with clinical and radiological finding. In adult Portal hypertension as a hepatic cause and in paediatric age group thalassemia is the most common indication for splenectomy.

Splenectomy versus conservative management for acute sequestration crises in people with sickle cell disease.

2015-09-07

Acute splenic sequestration crises are a complication of sickle cell disease, with high mortality rates and frequent recurrence in survivors of first attacks. Splenectomy and blood transfusion, with their consequences, are the mainstay of long-term management used in different parts of the world. This is a 2015 update of a Cochrane review first published in 2002, and previously updated in 2013. To assess whether splenectomy (total or partial), to prevent acute splenic sequestration crises in people with sickle cell disease, improved survival and decreased morbidity in people with sickle cell disease, as compared with regular blood transfusions. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register, which comprises of references identified from comprehensive electronic database searches and handsearching relevant journals and abstract books of conference proceedings.Additional trials were sought from the reference lists of the trials and reviews identified by the search strategy.Date of the most recent search: 10 June 2015. All randomized or quasi-randomized controlled trials comparing splenectomy (total or partial) to prevent recurrence of acute splenic sequestration crises with no treatment or blood transfusions in people with sickle cell disease. No trials of splenectomy for acute splenic sequestration were found. No trials of splenectomy for acute splenic sequestration were found. Splenectomy, if full, will prevent further sequestration and if partial, may reduce the recurrence of acute splenic sequestration crises. However, there is a lack of evidence from trials showing that splenectomy improves survival and decreases morbidity in people with sickle cell disease. There is a need for a well-designed, adequately-powered, randomized controlled trial to assess the benefits and risks of splenectomy compared to transfusion programmes, as a means of improving survival and decreasing mortality from acute splenic

It has been shown that inhibitors of the immune system reside in the spleen and inhibit the endogenous antitumor effects of the immune system. We hypothesized that splenectomy would inhibit the growth of relatively large non-small lung cancer (NSCLC) tumors by modulating the systemic inhibition of the immune system, and in particular Myeloid Derived Suppressor Cells (MDSC). The effect of splenectomy was evaluated in several murine lung cancer models. We found that splenectomy reduces tumor growth and the development of lung metastases, but only in advanced tumors. In immune-deficient NOD-SCID mice the effect of splenectomy on tumor growth and metastatic spread disappeared. Splenectomy significantly reduced the presence of MDSC, and especially monocytic-MDSC in the circulation and inside the tumor. Specific reduction of the CCR2+ subset of monocytic MDSC was demonstrated, and the importance of the CCL2-CCR2 axis was further shown by a marked reduction in CCL2 following splenectomy. These changes were followed by changes in the macrophages contents of the tumors to become more antitumorigenic, and by increased activation of CD8+ Cytotoxic T-cells (CTL). By MDSC depletion, and adoptive transfer of MDSCs, we demonstrated that the effect of splenectomy on tumor growth was substantially mediated by MDSC cells. We conclude that the spleen is an important contributor to tumor growth and metastases, and that splenectomy can blunt this effect by depletion of MDSC, changing the amount and characteristics of myeloid cells and enhancing activation of CTL.

Hollingsworth, Caroline L.; Rice, Henry E.

2010-01-01

The risks associated with total splenectomy, including overwhelming postsplenectomy infection, have led to an interest in the use of partial splenectomy as an alternative surgical option for children with congenital hemolytic anemias and hypersplenism. Partial splenectomy, a procedure designed to remove enough spleen to improve anemia and avoid complications of splenic sequestration while preserving splenic function, has shown promise in children. Radiologic imaging is essential for the preoperative evaluation and postoperative care for children undergoing partial splenectomy and offers a broad range of critical clinical information essential for care of these complex children. It is imperative for radiologists involved in the care of these children to be familiar with the surgical technique and imaging options for these procedures. This article reviews the surgical technique as well as the current status of various diagnostic imaging options used for children undergoing partial splenectomy, highlighting technical aspects and specific clinical information obtained by each modality.

In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure. The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups. Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

Full Text Available Introduction: Emergency department thoracotomy (EDT may serve as the last survival chance for patients who arrive at hospital in extremis. It is considered as an effective tool for improvement of traumatic patients’ outcome. The present study was done with the goal of assessing the outcome of patients who underwent EDT and its predictive factors. Methods: In the present study, medical charts of 50 retrospective and 8 prospective cases underwent emergency department thoracotomy (EDT were reviewed during November 2011 to June 2013. Comparisons between survived and died patients were performed by Mann-Whitney U test and the predictive factors of EDT outcome were measured using multivariate logistic regression analysis. P < 0.05 considered statistically significant. Results: Fifty eight cases of EDT were enrolled (86.2% male. The mean age of patients was 43.27±19.85 years with the range of 18-85. The mean time duration of CPR was recorded as 37.12±12.49 minutes. Eleven cases (19% were alive to be transported to OR (defined as ED survived. The mean time of survival in ED survived patients was 223.5±450.8 hours. More than 24 hours survival rate (late survived was 6.9% (4 cases. Only one case (1.7% survived to discharge from hospital (mortality rate=98.3%. There were only a significant relation between ED survival and SBP, GCS, CPR duration, and chest trauma (p=0.04. The results demonstrated that initial SBP lower than 80 mmHg (OR=1.03, 95% CI: 1.001-1.05, p=0.04 and presence of chest trauma (OR=2.6, 95% CI: 1.75-3.16, p=0.02 were independent predictive factors of EDT mortality. Conclusion: The findings of the present study showed that the survival rate of trauma patients underwent EDT was 1.7%. In addition, it was defined that falling systolic blood pressure below 80 mmHg and blunt trauma of chest are independent factors that along with poor outcome.

There is contradicting information in the veterinary literature regarding canine splenectomy and the increased risk for subsequent gastric dilatation-volvulus. The main purpose of this study was to determine the rate of occurrence of gastric dilatation-volvulus following splenectomy in medium to large breed dogs compared with a control group undergoing other abdominal procedures. Follow-up was performed by reviewing the medical records and conducting phone interviews. Weight, gender, and presence of a hemoabdomen at the time of surgery were not significantly associated with occurrence of gastric dilatation-volvulus, while increasing age was. Ten of 238 (4%) dogs in the splenectomy group and 3/209 (1.4%) dogs in the control group subsequently developed gastric dilatation-volvulus, which was not significantly different ( P = 0.08). While the findings approach significance and support a need for future investigation, the current recommendation for gastropexy at time of splenic removal should be made on a case by case basis and while considering previously documented risk factors.

A 70-year-old man with distal bile duct carcinoma underwent a subtotal stomach-preserving pancreaticoduodenectomy without adjuvant chemotherapy. One and a half years after the surgery, elevated levels of serum SPan-1(38.1 U/mL)were observed and CT scans demonstrated a solitary metastasis, 25mm in size, in segment 8 of the liver. The patient received 2 courses of gemcitabine-cisplatin combination chemotherapy. No new lesions were detected after chemotherapy and the patient underwent a partial liver resection of segment 8. The pathological examination revealed a metachronous distant metastasis originating from the bile duct carcinoma. Subsequently, the patient received S-1 adjuvant chemotherapy for 6 months. Following completion of all therapies, the patient survived without tumor recurrence for 3 years and 10 months after the initial operation. Thus, surgical interventions might be effective in improving prognosis among selected patients with postoperative liver metastasis of bile duct carcinoma.

Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

First experience with single incision laparoscopic surgery in Slovakia: concomitant cholecystectomy and splenectomy in an 11-year-old girl with hereditary spherocytosis.

Hereditary spherocytosis is an autosomal dominant inheritance disorder of the red blood cell membrane characterized by the presence of spherical-shaped erythrocytes (spherocytes) in the peripheral blood. The main clinical features include haemolytic anemia, variable jaundice, splenomegaly and cholelithiasis caused by hyperbilirubinemia from erythrocyte hemolysis. Splenectomy does not solve the congenital genetic defect but it stops pathological hemolysis in the enlarged spleen. If gallstones are present, it is appropriate to perform cholecystectomy at the time of splenectomy, although the patient has symptoms of gall bladder disease. We present the case of single incision laparoscopic surgical (SILS) concomitant splenectomy and cholecystectomy performed with conventional laparoscopic instruments in an 11-year-old girl with the diagnosis of hereditary spherocytosis. A 2-3 cm umbilical incision was used for the placement of two 5 mm trocars and one 10 mm flexible videoscope. Conventional laparoscopic dissector, grasper, Ligasure, Harmonic Ace and hemoclips were the main tools during surgical procedure. We prefer Single Incision Laparoscopic Surgery Foam Port (Covidien) as the single umbilical device for introduction into the abdominal cavity. First, we performed cholecystectomy, then the gallbladder was put aside over the liver and after that we peformed splenectomy. To remove the detached spleen and gallbladder, a nylon extraction bag is introduced through one of the port sites. The spleen is than morcellated in the bag with forceps and removed in fragments. After that we removed them and the umbilical fascial incision was closed. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Our experience shows that SILS splenectomy and cholecystectomy is feasible even in young children and

Between 1972 and 1985, 107 patients with chronic Idiopathic Thrombocytopenic Purpura underwent splenectomy. Platelet life span and sites of sequestration were studied with labelled platelets and external scanning. Medical treatment was always of scarce and transient effectiveness and had considerable side effects. Splenectomy had minimal complications and mortality and caused no hazard of overwhelming sepsis in adults. The results of splenectomy were very satisfying, especially when platelet sequestration was mainly splenic (remission in about 90% of patients). Surgical treatment is at present the most effective in patients with chronic ITP

Incidence of Bradycardia and Outcomes of Patients Who Underwent Orbital Atherectomy Without a Temporary Pacemaker.

2017-02-01

We analyzed the incidence of bradycardia and the safety of patients with severely calcified coronary lesions who underwent orbital atherectomy without the insertion of a temporary pacemaker. The presence of severely calcified coronary lesions can increase the complexity of percutaneous coronary intervention due to the difficulty in advancing and optimally expanding the stent. High-pressure inflations to predilate calcified lesions may cause angiographic complications like perforation and dissection. Suboptimal stent expansion is associated with stent thrombosis and restenosis. Orbital atherectomy safely and effectively modifies calcified plaque to facilitate optimal stent expansion. The incidence of bradycardia in orbital atherectomy is unknown. Fifty consecutive patients underwent orbital atherectomy from February 2014 to September 2016 at our institution, none of whom underwent insertion of a temporary pacemaker. The final analysis included 47 patients in this retrospective study as 3 patients were excluded because of permanent pacemaker implantation. The primary endpoint was significant bradycardia, defined as bradycardia requiring emergent pacemaker placement or a heart rate pacemaker appears to be safe.

To describe surgical techniques for multiple port laparoscopic splenectomy (MLS) in dogs and report short-term outcome. Retrospective case series. Dogs (n = 10) with naturally occurring splenic disease. Medical records (March 2012-March 2013) of dogs that had MLS were reviewed. Data retrieved included signalment, weight, clinical signs, physical examination findings, preoperative laboratory and ultrasonographic findings, port number, size, and location, patient positioning, additional procedures performed, surgical duration, histopathologic diagnosis, duration of hospitalization, and perioperative complications. Ten dogs (median weight, 28.7 kg; range, 20.2-46.0 kg) had MLS using a 3 or 4 port technique and a vessel-sealing device for tissue dissection along the splenic hilus. Dog positioning varied because of additional laparoscopic or laparoscopic-assisted procedures including adrenalectomy (n = 2), ovariectomy (1), gastropexy (1), and intestinal resection and anastomosis (1). Conversion to an open approach was necessary in 1 dog because of inadequate visibility caused by omental adhesions. One dog had hemorrhage from an omental vessel, but open conversion was not required. MLS was associated with little perioperative morbidity and few complications in this cohort of dogs and may be a reasonable option for surgical management of dogs requiring elective splenectomy. © Copyright 2014 by The American College of Veterinary Surgeons.

The primary objective of this study was to evaluate the impact of polypharmacy on primary and secondary adherence to evidence-based medication (EBM) and to measure factors associated with non-adherence among patients who underwent percutaneous coronary intervention (PCI). We conducted a retrospective analysis for patients who underwent PCI at a tertiary cardiac care hospital in Qatar. Patients who had polypharmacy (defined as ≥6 medications) were compared with those who had no polypharmacy at hospital discharge in terms of primary and secondary adherence to dual antiplatelet therapy (DAPT), beta-blockers (BB), angiotensin converting enzyme inhibitors (ACEIs) and statins. A total of 557 patients (mean age: 53±10 years; 85%; males) who underwent PCI were included. The majority of patients (84.6%) received ≥6 medications (polypharmacy group) while only 15.4% patients received ≥5 medications (nonpolypharmacy group). The two groups were comparable in term of gender, nationality, socioeconomic status and medical insurance. The non-polypharmacy patients had significantly higher adherence to first refill of DAPT compared with patients in the polypharmacy group (100 vs. 76.9%; p=0.001). Similarly, the non-polypharmacy patients were significantly more adherent to secondary preventive medications (BB, ACEI and statins) than the polypharmacy group. In patients who underwent PCI, polypharmacy at discharge could play a negative role in the adherence to the first refill of EBM. Further studies should investigate other parameters that contribute to long term non-adherence.

Aim: To evaluate the incidence and associated factors of postoperative intense pain and haemodynamic changes during radiofrequency ablation of hepatocellular carcinoma. Materials and methods: A total of 123 consecutive hepatocellular carcinoma patients who underwent radiofrequency ablation were prospectively recruited. Patient factors, tumour characteristics, procedural factors, intraoperative haemodynamic changes, complications, postoperative events, laboratory values before and after ablation, and postoperative pain were evaluated. Postoperative pain was scored using a visual analogue scale after the procedure. Results: The mean age of the patients was 65.6 ± 9.6 years. In multiple logistic regression analysis, patients who underwent general anaesthesia [odds ratio (95% CI): 2.68 (1.23–5.81); p = 0.013] and had more postoperative nausea and vomiting episodes [3.10 (1.11–8.63); p = 0.036] were associated with intense pain. These findings remain robust after propensity score matching. For mean difference values between before and after RFA, higher in change in aspartate transaminase (p = 0.026), alanine transaminase (p = 0.016) and white blood cell count (p = 0.015), and lower in change in haemoglobin (p = 0.009) were also correlated with intense pain. There was no significant difference in haemodynamic changes between the general anaesthesia and local anaesthesia group during ablation. Conclusion: General anaesthesia, postoperative nausea and vomiting, and laboratory factors were associated with postoperative intense pain in patients who underwent radiofrequency ablation. Counselling and modification of analgesics should be considered in patients with related factors for intense pain

OBJECTIVE: The recognition that splenectomy renders patients susceptible to lifelong risks of septic complications has led to routine attempts at splenic conservation after trauma. In 1990, the authors reported that over an 11-year study period involving 193 patients, splenorrhaphy was the most common splenic salvage method (66% overall) noted, with nonoperative management employed in only 13% of blunt splenic injuries. This report describes changing patterns of therapy in 190 consecutive patients with splenic injuries seen during a subsequent 6-year period (1990 to 1996). An algorithmic approach for patient management and pitfalls to be avoided to ensure safe nonoperative management are detailed. METHODS: Nonoperative management criteria included hemodynamic stability and computed tomographic examination without shattered spleen or other injuries requiring celiotomy. RESULTS: Of 190 consecutive patients, 102 (54%) were managed nonoperatively: 96 (65%) of 147 patients with blunt splenic injuries, which included 15 patients with intrinsic splenic pathology, and 6 hemodynamically stable patients with isolated stab wounds (24% of all splenic stab wounds). Fifty-six patients underwent splenectomy (29%) and 32 splenorrhaphy (17%). The mean transfusion requirement was 6 units for splenectomy survivors and 0.8 units for nonoperative therapy (85% received no transfusions). Fifteen of the 16 major infectious complications that occurred followed splenectomy. Two patients failed nonoperative therapy (2%) and underwent splenectomy, and one patient required splenectomy after partial splenic resection. There no missed enteric injuries in patients managed nonoperatively. The overall mortality rate was 5.2%, with no deaths following nonoperative management. CONCLUSIONS: Nonoperative management of blunt splenic injuries has replaced splenorrhaphy as the most common method of splenic conservation. The criteria have been extended to include patients previously excluded from this form

The function of the spleen in tumor development has been investigated for years. The relationship of the spleen with hepatocellular carcinoma (HCC), a huge health burden worldwide, however, remains unknown. The present study aimed to examine the effect of splenectomy on the development of HCC and the possible mechanism. Mouse hepatic carcinoma lines H22 and Hepa1-6 as well as BALB/c and C57 mice were used to establish orthotopic and metastatic mouse models of liver cancer. Mice were divided into four groups, including control group, splenectomy control group (S group), tumor group (T group) and tumor plus splenectomy group (T+S group). Tumor growth, metastases and overall survival were assessed at determined time points. Meanwhile, myeloid-derived suppressor cells (MDSCs) were isolated from the peripheral blood (PB), the spleen and liver tumors, and then measured by flow cytometery. It was found that liver cancer led to splenomegaly, and increased the percentage of MDSCs in the PB and spleen in the mouse models. Splenectomy inhibited the growth and progression of liver cancer and prolonged the overall survival time of orthotopic and metastatic models, which was accompanied by decreased proportion of MDSCs in the PB and tumors of liver cancer-bearing mouse. It was suggested that splenectomy could be considered an adjuvant therapy to treat liver cancer.

Treatment of prolymphocytic leukemia

Hollister, S. Jr.; Coleman, M.

1982-01-01

Prolymphocytic leukemia is characterized by marked splenomegaly, distinctive cellular morphologic characteristics, and a poor clinical course. Five patients with typical PL were treated systematically with vincristine/prednisone, chlorambucil/prednisone, splenic irradiation, splenectomy, and other chemotherapy regimens. No patient responded to vincristine/prednisone. Two patients responded to chlorambucil/prednisone, and four patients had brief responses to splenic irradiation. Two patients underwent splenectomy, one of whom had a prolonged clinical remissions. No other chemotherapy combinations were of value. The median survival was 33 months. Recommendations are made to use chlorambucil/prednisone or splenic irradiation as initial treatment. Splenectomy should be considered in patients refractory to these modalities. The course of PL may be more protracted than originally reported

The viability of omental autotransplantation of splenic tissue after splenectomy has been disputed. The authors followed up splenic implants by imaging with either Tc-99m tin colloid or heat-damaged RBCs to determine how early implants can be visualized and whether a difference exists between patients who underwent emergency splenectomy for trauma (nine patients) and those who underwent elective splenectomy (seven patients). In the latter group, splenectomy was performed for portal hypertension in six patients and for hematologic disorder (Wiscott Aldrich syndrome) in one. All patients were imaged 2-4 weeks and 6 months after surgery. In the first group, seven implants were seen at 2-4 weeks and all nine were seen by 6 months. In the second group, only two implants were seen at 2-4 weeks and four were seen at 6 months; two implants were not visualized even at 6 months. The implant of the patient with hematologic disorder was not seen before 6 months. The authors conclude that splenic implants can be visualized bu scintigraphic methods as early as 2-4 weeks after surgery, and that by 6 months all implants from normal spleen are viable. By contrast, spleen implants placed for portal hypertension or hematologic disorders may fail

Awake craniotomies (AC) could reduce neurological deficits compared with patients under general anesthesia, however, intraoperative seizure is a major reason causing awake surgery failure. The purpose of the study was to give a comprehensive overview the published articles focused on seizure incidence in awake craniotomy. Bibliographic searches of the EMBASE, MEDLINE,were performed to identify articles and conference abstracts that investigated the intraoperative seizure frequency of patients underwent AC. Twenty-five studies were included in this meta-analysis. Among the 25 included studies, one was randomized controlled trials and 5 of them were comparable studies. The pooled data suggested the general intraoperative seizure(IOS) rate for patients with AC was 8%(fixed effect model), sub-group analysis identified IOS rate for glioma patients was 8% and low grade patients was 10%. The pooled data showed early seizure rates of AC patients was 11% and late seizure rates was 35%. This systematic review and meta-analysis shows that awake craniotomy is a safe technique with relatively low intraoperative seizure occurrence. However, few RCTs were available, and the acquisition of further evidence through high-quality RCTs is highly recommended.

2014-01-01

Since the first laparoscopic splenectomy (LS) was reported in 1991, LS has become the gold standard for the removal of normal to moderately enlarged spleens in benign conditions. Compared with open splenectomy, fewer postsurgical complications and better postoperative recovery have been observed, but LS is contraindicated for hypersplenism secondary to liver cirrhosis in many institutions owing to technical difficulties associated with splenomegaly, well-developed collateral circulation, and increased risk of bleeding. With the improvements of laparoscopic technique, the concept is changing. This article aims to give an overview of the latest development in laparoscopic splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension. Despite a lack of randomized controlled trial, the publications obtained have shown that with meticulous surgical techniques and advanced instruments, LS is a technically feasible, safe, and effective procedure for hypersplenism secondary to cirrhosis and portal hypertension and contributes to decreased blood loss, shorter hospital stay, and less impairment of liver function. It is recommended that the dilated short gastric vessels and other enlarged collateral circulation surrounding the spleen be divided with the LigaSure vessel sealing equipment, and the splenic artery and vein be transected en bloc with the application of the endovascular stapler. To support the clinical evidence, further randomized controlled trials about this topic are necessary. PMID:24914339

Prolymphocytic leukemia is characterized by marked splenomegaly, distinctive cellular morphologic characteristics, and a poor clinical course. Five patients with typical PL were treated systematically with vincristine/prednisone, chlorambucil/prednisone, splenic irradiation, splenectomy, and other chemotherapy regimens. No patient responded to vincristine/prednisone. Two patients responded to chlorambucil/prednisone, and four patients had brief responses to splenic irradiation. Two patients underwent splenectomy, one of whom had a prolonged clinical remission. There were no complete remissions. No other chemotherapy combinations were of value. The median survival was 33 months. Recommendations are made to use chlorambucil/prednisone or splenic irradiation as initial treatment. Splenectomy should be considered in patients refractory to these modalities. The course of PL may be more protracted than originally reported

Several experimental studies have demonstrated that removal of the spleen accelerates liver regeneration after partial hepatectomy. While the mechanism of splenectomy promotes liver regeneration by the improvement of the formation of tight junction and the establishment of hepatocyte polarity is still unknown. We analyzed the cytokines, genes and proteins expression between 70% partial hepatectomy mice (PHx) and simultaneous 70% partial hepatectomy and splenectomy mice (PHs) at predetermined timed points. Compared with the PHx group mice, splenectomy accelerated hepatocyte proliferation in PHs group. The expression of Zonula occludens-1 (ZO-1) indicated that splenectomy promotes the formation of tight junction during liver regeneration. TNF-α, IL-6, HGF, TSP-1 and TGF-β1 were essential factors for the formation of tight junction and the establishment of hepatocytes polarity in liver regeneration. After splenectomy, Partitioning defective 3 homolog (Par 3) and atypical protein kinase C (aPKC) regulate hepatocyte localization and junctional structures in regeneration liver. Our data suggest that the time course expression of TNF-α, IL-6, HGF, TSP-1, and TGF-β1 and the change of platelets take part in liver regeneration. Combination with splenectomy accelerates liver regeneration by improvement of the tight junction formation which may help to establish hepatocyte polarity via Par 3-aPKC. This may provide a clue for us that splenectomy could accelerate liver regeneration after partial hepatectomy of hepatocellular carcinoma and living donor liver transplantation.

Spleen removal may be recommended during organ transplantation in ABO-incompatible recipients as well as for hypoperfusion of the grafted liver, besides conventional surgical indications, but elevation of serum lipids has been observed in certain contexts. Aiming to analyze the influence of two dietary regimens on lipid profile, an experimental study was conducted. Male Wistar rats (n = 86, 333.0 +/- 32.2 g) were divided in four groups: group 1: controls; group 2: sham operation; group 3: total splenectomy; group 4: subtotal splenectomy with upper pole preservation; subgroups A (cholesterol reducing chow) and B (cholesterol-rich mixture) were established, and diet was given during 90 days. Total cholesterol (Tchol), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and triglycerides were documented. After total splenectomy, hyperlipidemia ensued with cholesterol-reducing chow. Tchol, LDL, VLDL, triglycerides, and HDL changed from 56.4 +/- 9.2, 24.6 +/- 4.7, 9.7 +/- 2.2, 48.6 +/- 11.1, and 22.4 +/- 4.3 mg/dL to 66.9 +/- 11.4, 29.9 +/- 5.9, 10.9 +/- 2.3, 54.3 +/- 11.4, and 26.1 +/- 5.1 mg/dL, respectively. Upper pole preservation inhibited abnormalities of Tchol, HDL, VLDL, and triglycerides, and LDL decreased (23.6 +/- 4.9 vs. 22.1 +/- 5.1, P = 0.002). Higher concentrations were triggered by splenectomy and cholesterol-enriched diet (Tchol 59.4 +/- 10.1 vs. 83.9 +/- 14.3 mg/dL, P = 0.000), and upper-pole preservation diminished without abolishing hyperlipidemia (Tchol 55.9 +/- 10.0 vs. 62.3 +/- 7.8, P = 0.002). After splenectomy, hyperlipidemia occurred with both diets. Preservation of the upper pole tended to correct dyslipidemia in modality A and to attenuate it in subgroup B. (c) 2008 Wiley-Liss, Inc.

We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and⁄or anatomical anomalies. To determine the motor and anatomical causes of dysphagia. A total of 41 adults, followed at the Esophageal Atresia Clinic at Hôpital Saint-Luc (Montreal, Quebec), were approached to particpate in the present prospective study. Evaluation was completed using upper endoscopy, manometry and barium swallow for the participants who consented. The medical charts of respondents were systematically reviewed from the neonatal period to 18 years of age to assess medical and surgical history. All 41 patients followed at the clinic consented and were included in the study. Dysphagia was present in 73% of patients. Esophagogastroduodenoscopy was performed in 32 patients: hiatal hernia was present in 62% (n=20); esophageal diverticulum in 13% (n=4); macroscopic Barrett esophagus in 31% (n=10); and esophagitis in 19% (n=6). Histological esophagitis was present in 20% and intestinal metaplasia in 10%. There were no cases of dysplagia or adenocarcinoma. Esophageal manometry was performed on 56% of the patients (n=23). Manometry revealed hypomotility in 100% of patients and included an insufficient number of peristaltic waves in 96%, nonpropagating peristalsis in 78% and low-wave amplitude in 95%. Complete aperistalsis was present in 78%. The lower esophageal sphincter was abnormal in 12 (52%) patients, with incomplete relaxation the most common anomaly. Of the 41 patients, 29 (71%) consented to a barium swallow, which was abnormal in 13 (45%). The anomalies found were short esophageal dilation in 28%, delay in esophageal emptying in 14%, diverticula in 14% and stenosis in 7

Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

To compare the performance of microdose flare-up (MF) and flexible-multidose gonadotropin-releasing hormone (GnRH) antagonist protocols in poor responder patients who underwent intracytoplasmic sperm injection (ICSI). One hundred and 12 consecutive patients (217 cycles) suspected to have poor ovarian response were enrolled. Group 1 (MF GnRH agonist group) constituted 64 patients (135 cycles) who underwent MF GnRH agonist protocol. Group 2 (flexible-multidose GnRH antagonist group) constituted 48 patients (82 cycles) who underwent flexible-multidose GnRH antagonist protocol. The duration of stimulation (d) (11.5 +/- 2.1 vs. 10.4 +/- 2.7, p or = seven blastomeres and < 10% fragmentation at day 3 (35.9% vs. 65.1%, p < 0.05) were significantly lower in Group 1 when compared to Group 2. The number of embryos transferred (2.2 +/- 1.3 vs. 2.4 +/- 0.9), the clinical pregnancy per embryo transfer (16.3% vs. 25.8%), and the implantation rate (8.6% vs. 12.2%) were comparable between groups. Although the flexible-multidose GnRH antagonist protocol produced better oocyte and embryo parameters, the clinical pregnancy rate and the implantation rates were comparable between the flexible-multidose GnRH antagonist and MF protocols in poor responder patients.

The 3 phase 3 CHAMPION (Cangrelor vs Standard Therapy to Achieve Optimal Management of Platelet Inhibition) trials collectively demonstrated the safety of transitioning from cangrelor, a potent, parenteral rapidly-acting P2Y 12 inhibitor, to clopidogrel in patients who underwent percutaneous coronary intervention (PCI). However, variation in timing of therapy, site-specific binding, and drug half-lives may theoretically complicate switching to other oral P2Y 12 inhibitors. Since regulatory approval, limited data are available regarding the "real-world" safety and tolerability of transitioning to these more potent oral P2Y 12 antagonists. From November 2015 to January 2017, we evaluated the clinical profiles and efficacy and safety outcomes in cangrelor-treated patients who underwent PCI transitioned to clopidogrel (n = 42) or ticagrelor (n = 82) at a large, tertiary care center. Most patients receiving cangrelor underwent PCI with a drug-eluting stent for acute coronary syndrome via a radial approach in the background of unfractionated heparin. Stent thrombosis within 48 hours was rare and occurred in 1 patient treated with ticagrelor. Global Use of Strategies to Open Occluded Coronary Arteries-defined bleeding occurred in 20% of patients switched to ticagrelor and 29% of patients switched to clopidogrel, but none were severe or life-threatening. In conclusion, rates of stent thrombosis and severe/life-threatening bleeding were low and comparable with those identified in the CHAMPION program, despite use of more potent oral P2Y 12 inhibition.

A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

The severe local thermal trauma activates a number of systemic inflammatory mediators, such as TNF-α, NF-κB, resulting in a disruption of gut barrier. The gastrointestinal tight junction (TJ) is highly regulated by membrane-associated proteins including zonula occludens protein-1 (ZO-1) and occludin, which can be modulated by inflammatory cytokines. As splenectomy has been shown to reduce secretion of cytokines, we hypothesized that (1) severe scald injury up-regulates TNF-α and NF-κB, meanwhile down-regulates expression of ZO-1 and occludin, leading to the increased intestinal permeability, and (2) splenectomy can prevent the burn-induced decrease in ZO-1 and occludin expression, resulting in improved intestinal barrier. Wistar rats undergoing a 30% total body surface area (TBSA) thermal trauma were randomized to receive an accessorial splenectomy meanwhile or not. Intestinal injury was assessed by histological morphological analysis, and serum endotoxin levels, TNF-α, NF-κB, ZO-1 and occludin levels were detected by Western blotting in the terminal ileum mucosal tissue. 30% TBSA burn caused a significant increase in serum endotoxin levels, but NF-κB, and TNF-α, and the average intestinal villus height and mucosal thickness were decreased significantly. Burn injury could also markedly decrease the levels of ZO-1 and occludin in terminal ileum mucosal tissue (all PSplenectomy at 7th day after burn significantly reversed the burn-induced breakdown of ZO-1 and occludin (all PSplenectomy may provide a therapeutic benefit in restoring burn-induced intestinal barrier by decreasing the release of inflammatory cytokines and recovering TJ proteins.

Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

The peripheral immune response contributes to neurodegeneration after stroke yet little is known about how this process differs between males and females. The current study demonstrates that splenectomy prior to experimental stroke eliminates sex differences in infarct volume and activated brain monocytes/microglia. In the periphery of both sexes, activated T cells correlate directly with stroke outcome while monocytes are reduced by splenectomy only in males. This study provides new information about the sex specific mechanisms of the peripheral immune response in neurodegeneration after stroke and demonstrates the need for representation of both sexes in basic and clinical stroke research.

This study aimed to evaluate if the splenectomy alters the biodistribution of 99mTc-DMSA and renal function in Wistar rats. The animals were separated in the groups: splenectomy (n = 6) and control (n = 6). After splenectomy (15 days), the administration of 0.1 ml of 99mTc-DMSA IV (0.48 MBq) was carried out. Thirty minutes later, kidney, heart, lung, thyroid, stomach, bladder and femur and samples of blood were isolated. The organs were weighed, counted and the percentage of radioactivity /g (%ATI/g) determined. Serum urea and creatinine, hematocrit, leukocytes and platelets were measured. Statistics by t test (p<0.05) was done. There was a significant reduction in %ATI/g in kidney and blood (p<0.05) of splenectomized animals, a significant increase (p<0.05) of urea (88.8 ± 18.6 mg/dL) and creatinine (0.56 ± 0.08 mg/dL), compared to the controls (51.5±1.6, 0.37±0.02 mg/dL, respectively), as well as increase in platelets and leucocytes, and hematocrit reduction. The analysis of the results indicates that in rats, splenectomy seems to alter the renal function and the uptake of 99mTc-DMSA. (author)

Conclusion: An emergency splenectomy is an appropriate operative intervention for a grade V splenic laceration with hemoperitoneum, splenomegaly, and axillary lymphadenopathy regardless of the potential for a neoplastic process such as B-cell CLL. Post-splenectomy vaccinations and oncologic follow-up for systemic chemotherapy should be facilitated after recovery.

Intrathoracic extramedullary hematopoiesis (EMH) is a rare condition of the hereditary spherocytosis. EMH usually regresses or disappears after treatment; such as splenectomy in the case of spherocytosis. We report a case of hereditary spherocytosis. It is presented with an unilateral paravertebral posterior mediastinal mass. After splenectomy, it revealed shrinkage and fatty replacement on serial CT scans.

Twenty-three subjects who had a splenectomy as a result of trauma underwent scintigraphic evaluation with a sensitive heat-denatured sup(99m)Tc-labeled red blood cells (DRBC). This method enabled detection of ectopic splenic tissue foci (ESTF) as small as 1x1 cm in diameter. ESTF splenosis or accessory spleen was detected in 15 cases (65%), a higher incidence than previously reported. The size of the ESTF ranged from 1x1 to 5x10 cm (0.8-40 cm/sup 2/), and 53% were less than 2x2 cma (3 cm/sup 2/). A new multiparametric scintigraphic evaluating technique is described, which estimates the quantity of ESTF and its grade of activity, relative to that of the liver. The technique is a highly efficient assessor of ESTF function. Good correlation was found between the size and activity of the ESTF and the presence of Howell-Jolly bodies (HJB), but with a low sensitivity for detecting small ESTF. Correlation was low between residual splenic tissue and concentrations of IgM, IgA and IgG immunoglobulins. The sup(99m)Tc-DRBC method described is recommended for verification of ESTF existence, localization, and function.

The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Full Text Available INTRODUCTION : Bacterial translocation is the invasion of indigenous intestinal bacteria through the gut mucosa to normally sterile tissues and internal organs. Schistosomiasis may cause alterations in the immune system and damage to the intestines, portal system and mesenteric lymph nodes. This study investigated bacterial translocation and alterations in the intestinal microbiota and mucosa in schistosomiasis and splenectomized mice. METHODS : Forty female 35-day-old Swiss Webster mice were divided into the following four groups with 10 animals each: schistosomotic (ESF, splenectomized schistosomotic (ESEF, splenectomized (EF and control (CF. Infection was achieved by introduction of 50 Schistosoma mansoni (SLM cercariae through the skin. At 125 days after birth, half of the parasitized and unparasitized mice were subjected to splenectomy. Body weights were recorded for one week after splenectomy; then, the mice were euthanized to study bacterial translocation, microbiota composition and intestinal morphometry. RESULTS : We observed significant reductions in the weight increases in the EF, ESF and ESEF groups. There were increases of at least 1,000 CFU of intestinal microbiota bacteria in these groups compared with the CF. The EF, ESF and ESEF mice showed decreases in the heights and areas of villi and the total villus areas (perimeter. We observed frequent co-infections with various bacterial genera. CONCLUSIONS : The ESEF mice showed a higher degree of sepsis. This finding may be associated with a reduction in the immune response associated with the absence of the spleen and a reduction in nutritional absorption strengthened by both of these factors (Schistosoma infection and splenectomy.

Effects of splenectomy on the humoral immune system

Experiments were performed to investigate the influence of neonatal and adult splenectomy on humoral immunity in mice. In the bone marrow and lymph nodes of both groups of splenectomized mice the number of immunoglobulin (Ig)-positive (B) lymphocytes was significantly higher than in sham-operated mice. These higher numbers of B cells probably reflect a compensation for the absence of the B cell population of the spleen. Hardly any quantitative differences in the serum immunoglobulins were found between splenectomized and sham-splenectomized mice. Only for the IgM class was a significantly lower concentration found in the serum of splenectomized animals. This low concentration of IgM in the blood of splenectomized mice was caused by a failure of the remaining organs to compensate completely for the removal of the quantitatively important population of IgM-producing plasma cells in the spleen. Nevertheless, the number of precursors of IgM-producing plasma cells in bone marrow and lymph nodes and their ability to differentiate into IgM-producing plasma cells was not diminished by splenectomy. Probably the spleen provides a highly efficient environment for the differentiation into IgM-producing plasma cells. By investigating the synergistic ability of bone marrow cells and thymus cells from neonatally splenectomized mice it was found that these cells were fully capable of co-operating in the adoptive plaque-forming cell response to sheep red blood cells (SFBC).

2008-11-01

Full Text Available Diagnosis of abdominal splenosis is often undiagnosed until treatment for splenic rupture or splenectomy. This report describes a patient with splenosis mimicking hepatic tumor. The patient had a history of splenic trauma with splenectomy and chronic hepatitis C. After routine abdominal ultrasound revealed a liver nodule, further imaging studies, including magnetic resonance imaging, computed tomography and angiography, were performed. After the patient eventually underwent surgery, pathology revealed splenic tissue. Despite its distinguishable clinical features, splenosis is difficult to identify by modern imaging modalities. Therefore, accurate and timely diagnosis of this disease requires constant vigilance.

Newly named in 1989, Capnocytophaga canimorsus is a bacterial pathogen found in the saliva of healthy dogs and cats, and is transmitted to humans principally by dog bites. This review compiled all laboratory-confirmed cases, animal sources, and virulence attributes to describe its epidemiology, clinical features, and pathogenesis. An estimated 484 patients with a median age of 55 years were reported, two-thirds of which were male. The case-fatality rate was about 26%. Its clinical presentations included severe sepsis and fatal septic shock, gangrene of the digits or extremities, high-grade bacteremia, meningitis, endocarditis, and eye infections. Predispositions were prior splenectomy in 59 patients and alcoholism in 58 patients. Dog bites before illness occurred in 60%; additionally, in 27%, there were scratches, licking, or other contact with dogs or cats. Patients with meningitis showed more advanced ages, higher male preponderance, lower mortality, and longer incubation periods after dog bites than patients with sepsis (p spleens (p dog bites.

Full Text Available Objective: The major factor for developing malignant skin cancers is sunlight exposure. This study aimed to evaluate the demographics of patients with skin cancers who underwent surgery in Diyarbakır where the population is exposed to more sunlight than most other Turkish cities. Methods: The medical records of patients who underwent surgery for malignant skin cancer excision between 2011 and 2016 were searched using University Hospital’s patient database program. Data about patients’ demographics, cancer features, and the surgical techniques performed were collected. Results: Over a 5-year period, 190 patients underwent surgical excision. The male to female ratio was 1.56, and the mean age was 65.8 ± 15.7 (range, 20-94 years. The most common skin cancer was basal cell carcinoma (n=138, 72.7%, followed by squamous cell carcinoma (n=45, 23.7% and malignant melanoma (n=5, 2.6%. The most common surgery was primary excision, which was performed in 90 of 190 patients (47.36%; tissue reconstruction with a skin graft or flap surgery was required for the remaining 100 (52.63%, showing a significant difference (p<0.001. Conclusion: Basal cell carcinoma is the most common skin cancer, and less than half of the patients sought treatment immediately after they recognized the lesion. The public should be educated about skin cancers to increase early diagnosis and encourage timely treatment, thereby decreasing morbidity and mortality from skin cancer.

Accessory spleens of 1.5 cm in size were preoperatively identified by the combined use of computerized tomography and splenic scintigraphy in two patients with hematologic diseases. After the accessory spleen had been removed from the first patient, who had persistent hereditary spherocytosis and had undergone a splenectomy 15 months before, a postoperative decrease in hyperbilirubinemia was noted. In the other patient who had idiopathic thrombocytopenic purpura, a successful accessory splenectomy was done at the same time as her splenectomy, and was followed by 6 months' complete remission. These events indicate that preoperative investigations using computerized tomography and scintigraphy are indispensable for ruling out an accessory spleen in those patients for whom splenectomy needs to be done in order to alleviate hematologic disorders.

Splenectomy alters distribution and turnover but not numbers or protective capacity of de novo generated memory CD8 T cells.

Directory of Open Access Journals (Sweden)

2014-11-01

Full Text Available The spleen is a highly compartmentalized lymphoid organ that allows for efficient antigen presentation and activation of immune responses. Additionally, the spleen itself functions to remove senescent red blood cells, filter bacteria, and sequester platelets. Splenectomy, commonly performed after blunt force trauma or splenomegaly, has been shown to increase risk of certain bacterial and parasitic infections years after removal of the spleen. Although previous studies report defects in memory B cells and IgM titers in splenectomized patients, the effect of splenectomy on CD8 T cell responses and memory CD8 T cell function remains ill defined. Using TCR-transgenic P14 cells, we demonstrate that homeostatic proliferation and representation of pathogen-specific memory CD8 T cells in the blood are enhanced in splenectomized compared to sham surgery mice. Surprisingly, despite the enhanced turnover, splenectomized mice displayed no changes in total memory CD8 T cell numbers nor impaired protection against lethal dose challenge with Listeria monocytogenes. Thus, our data suggest that memory CD8 T cell maintenance and function remain intact in the absence of the spleen.

By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change

, have been treated by partial splenectomy. However, the splenic remnant, vascularized by the hilar vessels, may enlarge leading to recurrent splenomegaly and all its adverse effects. More than eighteen years of experience treating portal hypertension, splenic trauma, myeloid splenomegaly, splenomegalic somatic and sexual hypodevelopment, chronic lymphocytic lymphoma and cystadenoma of pancreatic tail by subtotal splenectomy, maintaining the upper pole supplied only by the splenogastric vessels showed that the splenic remnant does not increase its size. Based on evidence that the hilar vessels may contribute to the increase of the splenic remnant, we performed in five cases with Gaucher's disease subtotal splenectomy, maintaining the upper pole supplied only by the splenogastric vessels. The splenic remnant did not modify in size during a postoperative follow-up of more than twelve years, and the hematological parameters remained normal. Another patient whose splenogastric vessels were insufficient to maintain the upper splenic pole, was submitted to total splenectomy and autologous splenic tissue transplantation on the greater omentum. The autotransplant survived and presented with function. All six patients had uneventful postoperative follow-up in relation to the splenic conservative procedure. In conclusion, in presence of giant splenomegaly with severe hematologic and clinical symptoms the spleen must be resected in a conservative fashion such as subtotal splenectomy or total splenectomy followed by autotransplants of splenic tissue.

This retrospective study included 30 patients who underwent percutaneous core needle biopsy of their splenic lesions using 18- or 20-gauge needles between January 2001 and July 2016 in a single tertiary care center. The characteristics of the splenic lesions were determined by reviewing the ultrasound and computed tomography examinations. Acquisition rate and diagnostic accuracy were calculated, using pathologic results of the splenectomy specimen, clinical course and/or imaging follow-up as a reference standard. Post-procedure complications were identified from electronic medical records, laboratory findings and computed tomography images. Seventy-three specimens were obtained from the 30 patients and splenectomy was performed in 2 patients. Twenty-nine of the 30 patients had focal splenic lesions, while the remaining patient had homogeneous splenomegaly. Acquisition rate and diagnostic accuracy were 80.0% (24/30) and 76.7% (23/30), respectively. Perisplenic hemorrhage without hemodynamic instability developed in one patient. Ultrasound-guided percutaneous core needle biopsy of splenic lesions is a safe method for achieving a histopathologic diagnosis and can be considered as an alternative to splenectomy in patients with a high risk of splenectomy-related complications.

We evaluated therapy complications in 19 beta-thalassemia major patients (mean age from 3 years/5 months and 1 years/6 months) who were followed at II Pediatric Department-University of Bari. 3 out of 19 patients underwent allogenic BMT from matched related donor; 2 out of 19 underwent splenectomy. All of them were receiving hypertransfusion therapy and continuous chelation with DFO. In all patients we performed physical examination, laboratory assays, cardiac and endocrinologic function tests, serum HBV-HCV-HIV antibodies, otoscopy and audiometric test, fundus oculi, skeletal x-ray. 1 out of 19 patients, who was under 15, had a slight dilatation of left ventricle and arythmia. All patients were HBsAb positive. 4/19 patients were HCV Ab positive (ELISA test) with an increase in ALT-AST serum levels since at least 6 months. In 3 of them we assessed RIBA test, always positive. 3 of them underwent liver biopsy (1 iron overload 2 chronic active hepatitis). All patients were HIV Ab negative. 4/15 patients revealed low GH levels after Arginina test. 13 pre-pubescent patients had normal results with GNRH test but lower results after FSH test. 1 pubescent patient had gonadotropic hypophyseal deficit. 4 patients had subclinic hypothiroidism. We couldn't find any sequelas in bone-eyes-ears. Hypertransfusion therapy, chelation, profilaxis of infections improved length and quality of life in thalassemic patients. Hypogonadotropic hypogonadism remains a serious sequela and we think it needs to be treated.

Mouse bone marrow is barely capable of plaque-forming cell (PFC) activity during the primary response to sheep red blood cells (SRBC). However, during the secondary response, it becomes the major center of activity containing IgM-, IgG- and IgA-PFC. In the present paper the influence of splenectomy was studied on primary and secondary PFC activity in the bone marrow. Differences in primary and secondary bone marrow PFC responses are probably related to the presence of B and T memory cells in situ. Therefore the effect of splenectomy on the appearance of B and T memory cells in the bone marrow was also investigated. iv.plenectomy before intravenous (iv) immunization with 4 x 10 8 SRBC prevented any primary PFC activity in the bone marrow. The influence of splenectomy before priming on secondary PFC activity in the bone marrow depended on the priming dose of SRBC. Splenectomy before priming with 10 7 SRBC iv completely prevented IgM-, IgG-, and IgA-PFC activity in the bone marrow upon subsequent boosting with 4 x 10 8 SRBC iv. By means of cell transfer experiments it was shown that after splenectomy no B or T memory cells appeared in the bone marrow after priming with 10 7 SRBC iv. Cell transfer experiments showed that splenectomy before priming with 10 7 SRBC iv not only interfered with the appearance of B and T memory cells in the bone marrow, but also with the appearance of B memory cells in peripheral lymph nodes, mesenteric lymph node, Peyer's patches, thymus, and blood. Immunization of spenectomized mice with 4 x 10 8 SRBC iv induced the appearance of B memory cells in peripheral lymph nodes, mesenteric lymph node, Peyer's patches, thymus, and blood

The prognostic value of tumor deposits was evaluated by Kaplan–Meier and Cox regression analysis.Results: Tumor deposits were detected in 41.8% (61/146 of these SCRLM patients. Tumor deposits were significantly correlated with lymph node metastasis and nerve invasion of the primary tumors (P=0.002, P=0.041; respectively. The Kaplan–Meier survival analysis revealed that the overall survival (OS and disease-free survival (DFS of SCRLM patients with tumor deposits were significantly poorer than those with no tumor deposits (P=0.039, P=0.001; respectively. And with multivariate analysis, we found that positive tumor deposits were significantly associated with shorter DFS independent of lymph node status (P=0.002. Subgroup analysis found that of the 57 SCRLM patients with negative lymph node status, the OS and DFS of patients with positive tumor deposits were significantly shorter than those with negative tumor deposits (P=0.002 and P=0.031, respectively. Of the 89 patients with positive lymph node status, the OS of

Full text: The spleen is often involved in hematological malignancies; it is also the site of RBC destruction in thalassemia and ITP. In latter cases, splenectomy is often performed and postoperatively, detection of functioning splenic remnants affect the prognosis adversely. In this study, we assessed the usefulness of radionuclide techniques in : a) assessment of splenic function in primarily non-splenic diseases (benign or malignant), and b) detection of splenic remnant after splenectomy. 12 patients of splenomegaly and 5 patients after splenectomy underwent splenic imaging; imaging was performed using both 99m Tc-sulphur colloid (with first pass) and 99m Tc labelled heat denatured RBCs as tracers. Thus splenic perfusion, morphology and RBC trapping functions were all assessed. The colloid images usually matched the RBC images except in 2 cases where photogenic areas (presumably infarcts) were visualized on RBC scans that were missed on colloid scans. Three of the post splenectomy cases revealed functioning splenic remnants, which was also better visualized on RBC scans. It is concluded that radionuclide imaging could be used regularly for assessing function of spleen, or detecting splenic remnants

Splenic injury frequently occurs after blunt abdominal trauma; however, limited epidemiological data regarding mortality are available. We aimed to investigate mortality rate trends after blunt splenic injury in Japan. We retrospectively identified 1,721 adults with blunt splenic injury (American Association for the Surgery of Trauma splenic injury scale grades III-V) from the 2004-2014 Japan Trauma Data Bank. We grouped the records of these patients into 3 time phases: phase I (2004-2008), phase II (2009-2012), and phase III (2013-2014). Over the 3 phases, we analysed 30-day mortality rates and investigated their association with the prevalence of certain initial interventions (Mantel-Haenszel trend test). We further performed multiple imputation and multivariable analyses for comparing the characteristics and outcomes of patients who underwent TAE or splenectomy/splenorrhaphy, adjusting for known potential confounders and for within-hospital clustering using generalised estimating equation. Over time, there was a significant decrease in 30-day mortality after splenic injury (p splenic injury between 2004 and 2014, even after adjustment for within-hospital clustering and other factors independently associated with mortality. Over time, mortality rates decreased significantly after splenectomy/splenorrhaphy, but not after non-operative management. This information is useful for clinicians when making decisions about treatments for patients with blunt splenic injury.

The kinetics and biodistribution of HLA identical In-111 labeled platelets was studied in 10 leukemic patients with bone marrow transplants refractory to HLA matched platelet transfusions. Platelet survival time was short (x-bar +- SEM =1.64 +- 0.83 days). The mean recovery (extrapolated to zero time) was 29.9%, ranging from 14.2 to 63.0%. The deposition of the In-111 platelets in the liver and spleen was quantified by the geometric mean method using anterior and posterior imaging. In 3 patients liver uptake was significantly increased. The highest hepatic accumulation of In-111 occurred 2 hrs after injection (x-bar=76 +- 6% dose (SEM); at 48 hrs 62% of the dose remained in the liver. In 7 patients the spleen was the organ with the highest labeled platelet deposition. The splenic uptake of In-111 platelets in this group correlated with the spleen size (r=+0.95). At 30 min after injection 75+-6% of the dose was found in the spleen. Splenic activity decreased to 62% after 48 hrs. At the same time, In-111 liver accumulation increased from 14 to 31%. This finding suggests that In-111 may be released from the spleen and subsequently sequestered by the liver. Two patients with high splenic uptake underwent splenectomy after the In-111 platelet study. Both benefited from splenectomy in terms of platelet survival after transfusion

Laparoscopic splenectomy for a simultaneous wandering spleen along with an ectopic accessory spleen. Case report and review of the literature

Directory of Open Access Journals (Sweden)

Antonia Rizzuto

Full Text Available Background: Wandering spleen and accessory spleen are uncommon entity occurring during embryonic development. Wandering spleen results in an excessive mobility and migration of the spleen from its normal position in the left hypochondrium while accessory spleen is characterized by ectopic splenic masses or tissue disjointed from the main body of spleen.Due to the nonspecific and multiple symptoms the clinical diagnosis of both conditions is uncertain even with imaging techniques, such as CT and MRI. The coexistence of both diseases (wandering spleen ad accessory spleen is uncommon. Case report: A 17–year old European female with a history of minor beta thalassemia and recurrent attacks of abdominal pain. Pre- operative management consisted of routine laboratory tests, ultrasound, CT scan. An ectopic spleen along with an accessory spleen were diagnosed. After a multidisciplinary board a laparoscopic splenectomy was performed. Post-operative recovery was uneventful, and the patient was discharged on the 6th post-operative day with the indication to continue the therapy with low molecular weight heparin (LMWH for 30 days Conclusions: This case represents a simultaneous condition of wandering splenomegaly along with an ectopic wandering spleen. The coexistence of these two rare conditions is peculiar such as the age of the patient, as literature reports such diseases to affect children or more commonly people in the range of 20–40 years of age. Laparoscopic treatment for this particular condition is also unusual. Keywords: Ectopic spleen, Wandering spleen, Laparoscopic splenectomy

Currently, whether laparoscopic or open splenectomy is a gold standard option for spleen abnormalities remains in controversy. There is in deficiency of academic evidence concerning the surgical efficacy and safety of both comparative managements. In order to surgically appraise the applied potentials of both approaches, we hence performed this comprehensive meta-analysis on the basis of 15-year literatures. Via searching of PubMed, EMBASE, Web of Science, and Cochrane Library databases, overall 37 original articles were eligibly incorporated into our meta-analysis and subdivided into six sections. In accordance with the Cochrane Collaboration protocol, all statistical procedures were mathematically conducted in a standard manner. Publication bias was additionally evaluated by funnel plot and Egger's test. Irrespective of the diversified splenic disorders, laparoscopic splenectomy was superior to open technique owing to its fewer estimated blood loss, shorter postoperative hospital stay as well as lower complication rate (P  0.05). Technically, laparoscopic splenectomy should be recommended as a prior remedy with its advantage of rapid recovery and minimally physical damage, in addition to its comparably surgical efficacy against that of open manipulation.

Purpose: Second malignancies have been reported among patients who were treated by radiation therapy or chemotherapy alone or in combination. Studies have implied an increased risk of breast cancer in women who received radiotherapy as part of their treatment for Hodgkin's disease. This review was performed to determine if there is an association between splenectomy and subsequent breast cancer. Methods and Materials: One hundred and thirty-six female patients with histologically proven Hodgkin's disease were seen in the Division of Radiation Oncology between 1962 and 1985. All patients received mantle or mediastinal irradiation as part of their therapy. The risk of breast cancer was assessed and multiple linear regression analysis was performed on the following variables: patient age, stage, dose and extent of radiation field, time after completing radiation therapy, splenectomy, and chemotheraphy. Results: Breast cancer was observed in 11 of 74 splenectomized patients and in none of 62 patients not splenectomized. The mean follow-up was 13 years in splenectomized patients and 16 years, 7 months in nonsplenectomized patients. Nine patients developed invasive breast cancer and two developed ductal carcinoma in situ. Splenectomy was the only variable independently associated with an increased risk of breast cancer (p < 0.005) in multiple linear regression analysis; age, latency, and splenectomy considered together were also associated with an increased risk of breast cancer (p < 0.01). Conclusion: Our data show an increased risk of breast cancer in splenectomized patients who had treatment for Hodgkin's disease. A multiinstitutional survey may better define the influence of splenectomy relative to developing breast cancer in patients treated for Hodgkin's disease. The risk of breast cancer should be considered when recommending staging laparotomy, and we recommend close follow-up examination including routine mammograms for female patients successfully treated for

é-operatório. CONCLUSÃO: A desconexão ázigo-portal e esplenectomia promoveram queda imediata na pressão portal, com conseqüente diminuição do calibre das varizes esofágicas. Observou-se ainda que não é insignificante o risco de mortalidade e complicações graves relacionados a essa técnica.BACKGROUND: The main cause of portal hypertension in Brazil is the hepato-splenic form of mansonic schistosomiasis and the most employed technique for the surgical approach of this disease is the esophagogastric devascularization with splenectomy, generally associated to postoperative endoscopical esophageal varices sclerotherapy. The hemodynamic alterations after surgical treatment and its possible influence on the outcome are not well established. AIM: To evaluate the immediate impact of esophagogastric devascularization with splenectomy upon portal pressure as well as the results of the surgical treatment on digestive hemorrhage recurrence and on esophageal varices. METHODS: Nineteen patients with mean age of 37.9 years and portal hypertension and previous episodes of digestive hemorrhage caused by esophageal varices rupture due to hepato-splenic schistosomiasis were studied. None of the patients had received any treatment prior to the surgery and underwent to elective esophagogastric devascularization with splenectomy. Portal pressure was assessed at the beginning and at the end of esophagogastric devascularization with splenectomy through portal vein catheterization with a polyethylene catheter introduced through a jejunal branch vein. All patients were submitted to digestive endoscopy before and after the surgery, in order to classify the size of esophageal varices after esophagogastric devascularization with splenectomy according to Palmer’s classification. RESULTS: In all patients the portal pressure had diminished with a mean decrease of 31.3% after esophagogastric devascularization with splenectomy. In the postoperative endoscopic follow-up (1 month, the esophageal varices

Safe and reliable diabetes models are a key prerequisite for advanced preclinical studies on diabetes. Chemical induction is the standard model of diabetes in rodents and also widely used in large animal models of non-human primates and minipigs. However, uncertain efficacy, the potential of beta-cell regeneration, and relevant side effects are debatable aspects particularly in large animals. Therefore, we aimed to evaluate a surgical approach of total pancreatectomy combined with splenectomy for diabetes induction in an exploratory study in Goettingen minipigs. Total pancreatectomy was performed in Goettingen minipigs (n = 4) under general anesthesia and endotracheal intubation. Prior to surgery, a central venous line was established for drug application and blood sampling. After median laparotomy, splenectomy was performed and the lobular pancreas was carefully dissected with particular attention to the duodenal vascular arcade. Close monitoring of blood glucose was initiated immediately after surgery by standard glucometer measurement or continuous glucose monitoring systems (CGMS). Exogenous insulin was given by multiple daily subcutaneous (s.c.) injections or via insulin pump systems (CSII). Complete endogenous insulin deficiency was confirmed by intravenous glucose tolerance test (ivGTT) and measurement of c-peptide. For establishing a suitable regimen for diabetes management, the animals were followed for 4-6 weeks. Following pancreatectomy and splenectomy, the animals showed a quick recovery from surgery and initial analgetic medication and volume substitution could be terminated within 24 h. A rapid increase in blood glucose was observed immediately following pancreatectomy necessitating insulin therapy. The induced exocrine insufficiency did not cause any clinical symptoms. Complete insulin deficiency could be confirmed in all animals by determination of negative c-peptide during glucose challenge. The two regimen of insulin treatment (multiple daily

Conclusion: In our experience, MACE events were not higher in patients with FFR > 0.8 and kept under medical therapy and were similarly lower in patients with FFR ≤0.8 and underwent revascularisation (p = 0.73. Also MACE events were higher in patients with FFR ≤ 0.8 and did not undergo revascularisation compared to other two appropriately treated groups (p = 0.03. FFR based revascularization decision appears to be a safe strategy in Indian patients.

Periprocedural myocardial injury (PMI) is a major complication of percutaneous coronary intervention (PCI) and is associated with atherosclerotic coronary plaque and worse clinical outcomes. High-density lipoprotein cholesterol (HDL-C) is a protective factor for cardiovascular disease. However, the role of HDL-C subfractions, such as HDL2 cholesterol (HDL2-C) or HDL3 cholesterol (HDL3-C), in cardiovascular disease remains unclear. The purpose of the study was to investigate the relationship between HDL2-C and HDL3-C subfractions and the incidence of PMI in patients who underwent elective PCI. We enrolled 129 patients who underwent elective PCI for stable angina pectoris. PMI was defined as an increase in high-sensitivity troponin T levels > 5 times the upper normal limit (> 0.070 ng/mL) at 24 h after PCI. Serum HDL-C subfractions (HDL2-C and HDL3-C) were assessed using ultracentrifugation in patients with and those without PMI. HDL3-C levels were significantly lower in patients with PMI than in those without (15.1 ± 3.0 mg/dL vs. 16.4 ± 2.9 mg/dL, p = 0.016) and had an independent and inverse association with PMI (odds ratio, 0.86; 95% confidence interval, 0.74-0.99; p = 0.038). When divided by the cut-off value of HDL3-C for PMI (14.3 mg/dL), the incidence of PMI was significantly higher in low HDL3-C patients than in high HDL3-C patients (51.2% vs. 30.2%, p = 0.020). HDL3-C was an independent inverse predictor of PMI in patients who underwent elective PCI.

The study investigated the association between the location of transposed ovaries and posttreatment ovarian function in patients with early cervical cancer (IB1-IIA) who underwent radical hysterectomy and ovarian transposition with or without adjuvant therapies. Retrospective medical records were reviewed to enroll the patients with early cervical cancer who underwent ovarian transposition during radical hysterectomy at Samsung Medical Center between July 1995 and July 2012. Serum follicle-stimulating hormone (FSH) level was used as a surrogate marker for ovarian function. Twenty-one patients were enrolled. The median age and body mass index (BMI) were 31 years (range, 24-39 years) and 21.3 kg/m² (range, 17.7-31.2 kg/m²), respectively. The median serum FSH level after treatment was 7.9 mIU/mL (range, 2.4-143.4 mIU/mL). The median distance from the iliac crest to transposed ovaries on erect plain abdominal x-ray was 0.5 cm (range, -2.7 to 5.2 cm). In multivariate analysis, posttreatment serum FSH levels were significantly associated with the location of transposed ovaries (β = -8.1, P = 0.032), concurrent chemoradiation (CCRT) as an adjuvant therapy (β = 71.08, P = 0.006), and BMI before treatment (underweight: β = -59.93, P = 0.05; overweight: β = -40.62, P = 0.041). Location of transposed ovaries, adjuvant CCRT, and BMI before treatment may be associated with ovarian function after treatment. We suggest that ovaries should be transposed as highly as possible during radical hysterectomy to preserve ovarian function in young patients with early cervical cancer who might be a candidate for adjuvant CCRT and who have low BMI before treatment.

According to current guidelines, in patients without additional risk factors who have undergone aortic valve replacement with a bioprosthesis, anticoagulation in the first 3 months after surgery is still a matter of debate. According to current evidence, aspirin in low doses is a reasonable alternative to vitamin K antagonists (VKA). A comparison is made between the incidence of thrombotic and haemorrhagic complications in patients with low thrombotic risk who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico. The hypothesis: aspirin as monotherapy has a beneficial effect compared to VKA. The studied patients were the low thrombotic risk patients who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico from 2011 to 2015. The groups studied were: aspirin only, VKA only, and the combination of VKA plus aspirin. The patients were retrospectively followed-up for 12 months, and the thrombotic and haemorrhagic complications were documented. Of the 231 patients included in the study, only one patient in the VKA only group presented with a haemorrhagic complication. No thrombotic complications were observed. In the present study no thrombotic complications were observed in patients who did not receive anticoagulation in the first 3 months after an aortic valve replacement with a bioprosthesis after a follow up period of 12 months. This suggests that the use of aspirin only is safe during this period. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A. All rights reserved.

The influence of increased hepatic sequestration after splenectomy on the survival and osmotic fragility of red cells in rats, with reference to protein levels in diets

The sequestration of erythrocytes in rats was studied using an isologous 51-Cr labeled population of either normal or N-ethyl-maleimide treated red cells. Experiments were performed for observing the effects of the change in the hepatic sequestration of altered red cells on the osmotic fragility and the survival time of circulating red cells. The rate of sequestration in liver at different period after splenectomy was measured with respect to the survival time and osmotic fragility of red cells. The parameters of the proliferative response imposed on liver were also observed. The spleen sequestered selectively damaged red cells, while the liver compensated and overshot the sequestration for spleen after splenectomy. The sequestering response in liver increased gradually and reached the maximum level around 8 weeks after splenectomy, and then declined toward the control level. This compensatory response in liver was not observed in the rats fed with low protein diet. Therefore, the proliferative response imposed on liver by an extra work after splenectomy was not stimulated in the rats fed with low protein diet. Splenectomy prolonged erythrocyte survival and reduced the osmotic fragility of normal red cells, but the compensatory increase in the sequestration of damaged red cells in liver did not alter the survival and osmotic fragility of normal red cells. This fact indicates that the increased sequestration of reticuloendothelial cells in liver is basically reparative, and it is impossible to compensate for the absence of the spleen because of the inability to duplicate certain anatomic features peculiar to the spleen.

Introduction: Our aim was to perform a comparative study of short-term cardiovascular autonomic control in cardiac surgery patients who underwent coronary artery bypass grafting (CABG) or surgical correction of valvular heart disease (SCVHD ). Methods: The synchronous 15 minutes records of heart rate variability (HRV) and finger's photoplethysmographic waveform variability (PPGV) were performed in 42 cardiac surgery patients (12 women) aged 61.8 ± 8.6 years (mean ± standard deviation), who underwent CABG, and 36 patients (16 women) aged 54.2 ± 14.9 years, who underwent SCVHD , before surgery and in 5-7 days after surgery. Conventional time and frequency domain measures of HRV and index S of synchronization between the slow oscillations in PPGV and HRV were analyzed. We also calculated personal dynamics of these indices after surgery. Results: We found no differences ( Р > 0.05) in all studied autonomic indices (preoperative and post-surgery) between studied patients' groups, except for the preoperative heart rate, which was higher in patients who underwent SCVHD ( P = 0.013). We have shown a pronounced preoperative and post-surgery variability (magnitude of inter-quartile ranges) of all autonomic indices in studied patients. In the cluster analysis based on cardiovascular autonomic indices (preoperative and post-surgery), we divided all patients into two clusters (38 and 40 subjects) which did not differ in all clinical characteristics (except for the preoperative hematocrit, P = 0.038), index S, and all post-surgery HRV indices. First cluster (38 patients) had higher preoperative values of the HR, TP, HF, and HF%, and lower preoperative values of the LF% and LF/HF. Conclusion: The variability of cardiovascular autonomic indices in on-pump cardiac surgery patients (two characteristic clusters were identified based on preoperative indices) was not associated with their clinical characteristics and features of surgical procedure (including cardioplegia).

To study the prevalence and management of splenic trauma in relation to its mode and grade. All cases admitted in emergency with abdominal trauma and splenic injury. The data of all the patients who had splenic trauma was entered on a proforma and analyzed. A total of 44 patients with ages between 20-40 years presented with splenic injury; 32(72.7%) were male. The commonest mode of splenic trauma was blunt abdominal injury (50%), and most (47%) patients had Grade- III injury. Splenectomy was carried out in 84% patients, while 9% underwent splenic salvage. Seven (15.9%) patients with splenectomy died in the series. Splenic injury was mostly caused by blunt abdominal trauma. Proper assessment of the grade of injury at the time of laparotomy resulted in more splenic salvage procedures with decreased risk of complications. (author)

Over the past 2 decades, laparoscopy has been established as a superior technique in many general surgery procedures. Few studies, however, have examined the impact of the use of a laparoscopic approach in patients with symptomatic congestive heart failure (CHF). Because pneumoperitoneum has known effects on cardiopulmonary physiology, patients with CHF may be at increased risk. This study examines current trends in approaches to patients with CHF and effects on perioperative outcomes. The 2005-2011 National Surgical Quality Improvement Program Participant User File was used to identify patients who underwent the following general surgery procedures: Appendectomy, segmental colectomy, small bowel resection, ventral hernia repair, and splenectomy. Included for analysis were those with newly diagnosed CHF or chronic CHF with new signs or symptoms. Trends of use of laparoscopy were assessed across procedure types. The primary endpoint was 30-day mortality. The independent effect of laparoscopy in CHF was estimated with a multiple logistic regression model. A total of 265,198 patients were included for analysis, of whom 2,219 were identified as having new or recently worsened CHF. Of these patients, there were 1,300 (58.6%) colectomies, 486 (21.9%) small bowel resections, 216 (9.7%) ventral hernia repairs, 141 (6.4%) appendectomies, and 76 (3.4%) splenectomies. Laparoscopy was used less frequently in patients with CHF compared with their non-CHF counterparts, particularly for nonelective procedures. Baseline characteristics were similar for laparoscopy versus open procedures with the notable exception of urgent/emergent case status (36.4% vs 71.3%; P surgery procedures, particularly in urgent/emergent cases. Despite these patterns and apparent preferences, laparoscopy seems to offer a safe alternative in appropriately selected patients. Because morbidity and mortality were considerable regardless of approach, further understanding of appropriate management in this

To compare the PSA value at the last follow-up of patients who underwent prostate low-dose rate brachytherapy (LDR-BT) with that of patients who underwent intensity-modulated radiation therapy (IMRT). A total of 610 prostate cancer patients (cT1c-3bN0M0) were enrolled, and 445 of them underwent LDR-BT, while 165 received IMRT (74-76 Gy). The median follow-up period of these two groups was 75 months (LDR-BT) and 78 months (IMRT), respectively. We also evaluated the biochemical recurrence (BCR)-free rate using two definitions (Phoenix definition and PSA ≥ 0.2 ng/mL). The percentage of patients who achieved PSA LDR-BT group and 49.7% in the IMRT group (p LDR-BT group and 32.1% in the IMRT group (p LDR-BT groups was 89.5 and 95.0% (p LDR-BT groups, respectively (p LDR-BT was significantly lower than that of IMRT, and this result was particularly marked in patients with a normal testosterone level at the last follow-up.

PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients' responses were graded according to the Miller-Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR ( P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens ( P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.

Splenic artery aneurysm (SAA) is a rare and extremely difficult diagnosis. A rare case of a ruptured SAA in a 38-year old female, firstly treated with endovascular embolization and then with splenectomy, is presented. A 38-year old female presented to the emergency department with epigastric pain and fainting episodes. Direct catheter angiography revealed a ruptured SAA and distal, as well as proximal coil embolization was performed. Due to abdominal compartment syndrome the patient underwent open surgery with splenic artery ligation and splenectomy. Postoperative she showed signs of sepsis and was treated with i.v. fluids, steroids, packed red blood cells, platelets, fresh frozen plasma and antimicrobial treatment. Additionally, a multidrug resistant Acinetobacter baumanni was yielded from the urine culture. She had a satisfactory recovery. She is followed up a total of 5 years with no signs of overwhelming post-splenectomy infection syndrome. Direct catheter angiography is a very helpful option in diagnosis, as well as treatment, but a close monitoring after embolization is essential. Furthermore, post-splenectomy sepsis is a severe disease with high mortality rates that requires immediate appropriate treatment.

Forty-two patients with traumatic blunt splenic injuries were admitted over a six year period. Vehicular-related collisions and fall from height accounted for the injuries in 38 (90.5%) of them. Eleven (26.2%) underwent immediate surgery (7 splenectomy and 4 splenorrhaphy), while the remaining 31 patients were treated nonoperatively of which 3 underwent angio-embolisation. Twenty seven patients had either grade III or IV splenic injuries. Operative management was more likely in patients with lower haemoglobin or with more severe splenic injury. Nonoperative management can be adopted in patients with blunt isolated splenic injuries but operative management is still indispensable in certain instances.

We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

Decrease or loss in splenic filtration function may influence the hemorheological state. To follow-up the long-term effects of splenectomy, spleen autotransplantation and spleen resections on red blood cell aggregation in a canine model. Beagle dogs were subjected to control (n = 6), splenectomy (SE, n = 4), spleen autotransplantation (AU, Furka's spleen-chip method, n = 8) or partial and subtotal spleen resection (n = 4/each) groups, and followed-up for 18 postoperative (p.o.) months. Erythrocyte aggregation was determined in parallel by light-transmittance aggregometry (Myrenne MA-1 aggregometer) and syllectometry (LoRRca). Erythrocyte aggregation decreased three months after splenectomy, with lower aggregation index and elongated aggregation time. It was more or less associated with relatively lower hematocrit and fibrinogen concentration. However, in autotransplantated animals a relatively higher fibrinogen did not increase the aggregation markedly. Spleen resection resulted in the most controversial red blood cell aggregation findings, and it seems, that the degree of the resection is an influencing factor. Splenectomy alters erythrocyte aggregation, spleen autotransplantation can be useful to preserve filtration function. However, the degree of restoration shows individual differences with a kind of 'functional periodicity'. Spleen resection controversially influences erythrocyte aggregation parameters. The subtotal resection is supposed to be worse than spleen autotransplantation.

Full Text Available Background: Due to the presence of radiosensitive organs in the abdominopelvic region and increasing the number of requests for CT scan examinations, concerns about increasing radiation doses in patients has been greatly elevated. Therefore, the goal of this study was to determine the absorbed dose of radiosensitive organs and the effective dose in patients underwent abdominopelvic CT scan using ImPACT CT patient dosimetry Calculator (version 1.0.4, Imaging Performance Assessment on Computed Tomography, www.impactscan.org. Methods: This prospective cross-sectional study was conducted in Imam Reza Hospital from November to February 2015 February 2015 in the Imam Reza Hospital, in Urmia, Iran. The demographic and dosimetric information of 100 patients who underwent abdominopelvic CT scan in a 6-slice CT scanner were obtained through the data collection forms. The demographic data of the patients included age, weight, gender, and BMI. The dosimetric parameters included pitch value, CT dose volume index (CTDIvol, dose-length product (DLP, tube voltage, tube current, exposure time, collimation size, scan length, and scan time. To determine the absorbed dose of radiosensitive organs and also the effective dose in patients, ImPACT CT patient dosimetry calculator was used. Results: The results of this study demonstrated that the mean and standard deviation (SD of patients' effective dose in abdominopelvic CT scan was 4.927±0.164 mSv. The bladder in both genders had the greatest mean organ dose, which was 64.71±17.15 mGy for men and 77.56±18.48 mGy for women (P<0.001. Conclusion: The effective dose values of this examination are in the same range as previous studies, as well as International Commission on Radiological Protection (ICRP recommendations. However, the radiation dose from CT scan has the largest contribution to the medical imaging. According to the ALARA principle, it is recommended that the scan parameters, especially mAs, should be

From 1983 through 1989, 141 untreated patients with Hodgkin's disease underwent CT of the abdomen. They subsequently underwent staging laparotomy plus splenectomy and multiple biopsies of liver and lymph nodes, at the Institute of Radiology and Hematology, University 'La Sapienza', Rome. CT results were compared with surgical findings to evaluate CT sensitivity, specificity, and overall accuracy. The cases from this series were divided into two groups depending on the characteristics of the CT scanners employed. From 1983 to 1985, 78 patients were examined with 3nd-generation CT units; from 1986 to 1989, 63 patients underwent CT performed with 3rd-generation scanner. The results from the two groups were analyzed according to these parameters. A total number of 622 biopsies were performed, of spleen, liver and lymph nodes. CT sensitivity, specificity, and overall accuracy were: 22.9% (group I) vs 43.7% (group II), 83.1% vs 92%, and 68.4% vs 81.2% for lymph nodes; 28.1% vs 36.3%, 93.5% vs 98%, and 66.7% vs 87.3% for the spleen, and 12.5% vs 42.8%, 97.1% vs 98.2% and 88.5% vs 92.1% for the liver. Our results demonstrate an obvious increase in reliability with newer units, even though a high percentage of false-negatives were still observed in our series, which caused understaging in 19.4% of cases vs 24.4 in group I

The influence of preinfarction angina pectoris (AP) on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) remains controversial. In 5,429 patients with acute myocardial infarction (AMI) enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto AMI Registry, the present study population consisted of 3,476 patients with STEMI who underwent primary PCI within 24 hours of symptom onset and in whom the data on preinfarction AP were available. Preinfarction AP defined as AP occurring within 48 hours of hospital arrival was present in 675 patients (19.4%). Patients with preinfarction AP was younger and more often had anterior AMI and longer total ischemic time, whereas they less often had history of heart failure, atrial fibrillation, and shock presentation. The infarct size estimated by peak creatinine phosphokinase was significantly smaller in patients with than in patients without preinfarction AP (median [interquartile range] 2,141 [965 to 3,867] IU/L vs 2,462 [1,257 to 4,495] IU/L, p <0.001). The cumulative 5-year incidence of death was significantly lower in patients with preinfarction AP (12.4% vs 20.7%, p <0.001) with median follow-up interval of 1,845 days. After adjusting for confounders, preinfarction AP was independently associated with a lower risk for death (hazard ratio 0.69, 95% confidence interval 0.54 to 0.86, p = 0.001). The lower risk for 5-year mortality in patients with preinfarction AP was consistently observed across subgroups stratified by total ischemic time, initial Thrombolysis In Myocardial Infarction flow grade, hemodynamic status, infarct location, and diabetes mellitus. In conclusion, preinfarction AP was independently associated with lower 5-year mortality in patients with STEMI who underwent primary PCI. Copyright © 2014 Elsevier Inc. All rights reserved.

Full Text Available Abstract Introduction Little is known about splenic rupture in patients who develop systemic acquired A amyloidosis. This is the first report of a case of atraumatic splenic rupture in a patient with acquired A amyloidosis from chronic injection drug use. Case presentation A 58-year-old Caucasian man with a long history of injection drug use, hospitalized for infective endocarditis, experienced atraumatic splenic rupture and underwent splenectomy. Histopathological and microbiological analyses of the splenic tissue were consistent with systemic acquired A amyloidosis, most likely from injection drug use, that led to splenic rupture without any recognized trauma or evidence of bacterial embolization to the spleen. Conclusion In patients with chronic inflammatory conditions, including the use of injection drugs, who experience acute onset of left upper quadrant pain, the diagnosis of atraumatic splenic rupture must be considered.

We developed a new risk factor profile for contrast-induced acute kidney injury (CI-AKI) under a new definition in patients who underwent an emergency percutaneous coronary intervention (PCI). Consecutive patients (n = 1061) who underwent an emergency PCI were divided into a derivation group (n = 761) and a validation group (n = 300). The rates of CI-AKI were 23.5% (definition 1: serum creatinine [SCr] increase ≥25% in 72 hours), 4.3% (definition 2: SCr increase ≥44.2 μmol/L in 72 hours), and 7.0% (definition 3: SCr increase ≥44.2 μmol/L in 7 days). Due to the high sensitivity of definition 1 and the high rate of missed cases for late diagnosis of CI-AKI under definition 2, definition 3 was used in the study. The risk factor profile included body surface area 15.00 × 10 9 /L ( P = .047), estimated glomerular filtration rate 133 μmol/L ( P = .007), intra-aortic balloon pump application ( P = .006), and diuretics administration ( P risk factor profile of CI-AKI under a new CI-AKI definition in emergency PCI patients is easily applicable with a useful predictive value.

We report the case of a 68-year-old man who was diagnosed with Fournier's gangrene (FG), which developed during immunosuppresive treatment for idiopathic thrombocytopenic purpura (ITP). The patient was administered steroids for ITP but on the 36th day, he developed FG and septic shock. We initiated antibiotic treatment and drained a periproctal abscess immediately. On day 53, extensive drainage to progressive FG and a splenectomy was performed, following which both FG and thrombocytopenia improved. This is the first case of FG has developing in a ITP patient. It appears that high-dose immunoglobulin therapy and splenectomy should be considered earlier especially for a patient complicated with FG.

The spleen is one of the most commonly injured abdominal solid organs during blunt trauma. Modern management of splenic trauma has evolved to include non-operative therapies, including observation and angioembolization to preclude splenectomy in most cases of blunt splenic injury. Despite the shift in management strategies, relatively little is known about the hematologic changes associated with these various modalities. The aim of this study was to determine if there are significant differences in hematologic characteristics over time based on the treatment modality employed following splenic trauma. We hypothesized that alterations seen in hematologic parameters would vary between observation (OBS), embolization (EMB), and splenectomy (SPL) in the setting of splenic injury. An institutional review board-approved, retrospective study of routine hematologic indices examined data between March 2000 and December 2014 at three academic trauma centers. A convenience sample of patients with splenic trauma and admission lengths of stay >96 h was selected for inclusion, resulting in a representative sample of each sub-group (OBS, EMB, and SPL). Basic demographics and injury severity data (ISS) were abstracted. Platelet count, red blood cell (RBC) count and RBC indices, and white blood cell (WBC) count with differential were analyzed between the time of admission and a maximum of 1080 h (45 days) post-injury. Comparisons between OBS, EMB, and SPL groups were then performed using non-parametric statistical testing, with statistical significance set at p splenic injury grade varied by interventional modality (grade 4 for SPL, 3 for EMB, and 2 for OBS, p splenic injuries managed with SPL, EMB, or OBS. As expected, observed WBC counts were highest following SPL, then EMB, and finally OBS. No differences were noted in RBC count between the three groups, but RDW was significantly greater following SPL compared to EMB and OBS. We also found that MCV was highest following OBS

Nuclear factor of activated T-cells 5 (NFAT5) is known to be correlated with migration or invasion of tumor cells based on previous in vitro studies. The aim of this study was to analyze the relationship between NFAT5 expression and clinical prognosis in non-small cell lung cancer (NSCLC) patients who underwent surgical resection. A total of 92 NSCLC patients who underwent surgical resection were enrolled. The tissue microarray core was obtained from surgically resected tumor specimens. NFAT5 expression was evaluated by immunohistochemistry. Relationships of NFAT5 expression with disease recurrence, overall survival, and disease-free survival (DFS) were analyzed. The mean age of 92 patients was 63.7 y. The median follow-up duration was 63.3 mo. Fifty-one (55%) patients exhibited positive expression of NFAT5. Disease recurrence in the NFAT5-positive group was significantly (P = 0.022) higher than that in the NFAT5-negative group. NFAT5-positive expression (odds ratio: 2.632, 95% confidence interval: 1.071-6.465, P = 0.035) and pathologic N stage (N1-2 versus N0; odds ratio: 3.174, 95% confidence interval: 1.241-8.123, P = 0.016) were independent and significant risk factors for disease recurrence. DFS of the NFAT5-positive group was significantly worse than that of the NFAT5-negative group (89.7 versus 48.7 mo, P = 0.011). A multivariate analysis identified NFAT5 expression (P < 0.029) as a significant independent risk factor for DFS of patients with postoperative pathologic T and N stages (P < 0.001 and P = 0.017, respectively). NFAT5 expression is a useful prognostic biomarker for NSCLC patients who underwent surgical resection. Copyright © 2018 Elsevier Inc. All rights reserved.

Despite recent advances in the treatment of advanced gastric carcinomas, no satisfactory outcomes are available because of micrometastases and free-floating carcinoma cells already existing in the peritoneal cavity. From 1990, we started using intraperitoneal hyperthermo-chemo-perfusion (IHCP) to prevent and to treat peritoneal metastasis after surgical resection of stomach cancer. We analyzed 103 serosa-invasive gastric carcinoma patients who underwent surgical resection between 1990 and 1995. Fifty-two patients who received surgery plus IHCP were compared with 51 patients who underwent surgery only, as controls. IHCP was administered for 2 h with an automatic IHCP device (closed-circuit system) just after surgical resection, with the patient under hypothermic general anesthesia (32.4 degrees C-34.0 degrees C). As perfusate, we used 1.5% peritoneal dialysis solution mixed with 10 micrograms/ml of mitomycin-C (MMC), warmed at an inflow temperature of over 44 degrees C. The overall 5-year survival rate (5-YSR) of the 103 patients was 29.97%. The 5-YSR was higher in the IHCP group than in the control group, at 32.7% and 27.1%, respectively, but this difference was not significant. However, in the 65 serosa-invasive gastric carcinoma patients (excluding those in stage IV) the 5-YSR was significantly higher (P = 0.0379) in the IHCP group than in the control group, at 58.6% and 44.4%, respectively. On multivariate analysis of all 103 patients, depth of tumor invasion and lymph node metastasis were significant factors for survival, whereas significant factors on univariate analysis, such as combined operation, distant metastasis, and peritoneal metastasis, were not significant. The most common recurrence patterns were loco-regional in the IHCP group and peritoneal in the control group. Complete cytoreductive surgery plus IHCP is effective to prevent and to treat peritoneal metastasis, and it should lead to long-term survival for serosa-invasive gastric carcinoma patients

Owing to the increasing population of elderly patients, a large number of patients with degenerative spondylosis are currently being surgically treated. Although basic measures for decreasing postoperative surgical infections (PSIs) are considered, it still remains among the leading causes of morbidity and mortality. The aim of this retrospective analysis is to present possible causes leading to PSI in patients who underwent surgery for lumbar degenerative spondylosis and highlight how it can be avoided to decrease morbidity and mortality. The study included 540 patients who underwent posterior stabilization due to degenerative lumbar stenosis between January 2013 and January 2014. The data before and after surgery was retrieved from the hospital charts. Patients with degenerative lumbar stenosis who were operated upon in this study had >2 levels of laminectomy and facetectomy. For this reason, posterior stabilization was performed for all the patients included in this study. Determining the causes of postoperative infection (PI) following spinal surgeries performed with instrumentation is a struggle. Seventeen different parameters that may be related to PI were evaluated in this study. The presence of systemic diseases, unknown glove perforations, and perioperative blood transfusions were among the parameters that increased the prevalence of PI. Alternatively, prolene sutures, double-layered gloves, and the use of rifampicin Sv (RIS) decreased the incidence of PI. Although the presence of systemic diseases, unnoticed glove perforations, and perioperative blood transfusions increased PIs, prolene suture material, double-layered gloves, and the use of RIS decreased PIs.

Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks. Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass. Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014. Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively. Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

Although multigene panel testing is increasingly common in patients with cancer, the relationship between its use among breast cancer patients with non-BRCA mutations or variants of uncertain significance (VUS) and disease management decisions has not been well described. This study evaluated the rate and predictive factors of CPM patients who underwent multigene panel testing. Three hundred and fourteen patients with breast cancer who underwent multigene panel testing between 2014 and 2017 were included in the analysis. Of the 314 patients, 70 elected CPM. Election of CPM by gene status was as follows: BRCA carriers (42.3%), non-BRCA carriers (30.1%), and VUS (10.6%). CPM election rates did not differ between non-BRCA carriers and BRCA carriers (P = 0.6205). Among non-BRCA carriers, negative hormone receptor status was associated with CPM (P = 0.0115). For those with a VUS, hormone receptor status was not associated with CPM (P = 0.1879). Although the rate of CPM between BRCA carriers and non-BRCA carriers was not significantly different, the predictors of CPM were different in each group. Our analyses shed the light on the increasing use of CPM among patients who are non-BRCA carriers as well those with a VUS. Our study elucidates the differing predictive factors of CPM election among BRCA carriers, non-BRCA carries, and those with a VUS. Our findings reveal the need for providers to be cognizant that non-BRCA genes and VUS drive women to elect CPM despite the lack of data for contralateral breast cancer risk associated with these genes. © 2018 The Authors.

Full Text Available Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS. Three main components (naringin, naringenin, and hesperetin were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n=47 and control group (CG, received 20 mg placebo daily, n=48. After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group (P>0.01. The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability.

Normal young piglets and miniature piglets of the Gottingen breed were used as animal models for autotransplantation of splenic fragments. In pigs, regeneration kinetics seem to be comparable to man. Even after six mo, only small splenic nodules with a reduced blood flow were found. No effective stimulator of splenic regeneration has been found for pigs. Pig spleen size and blood supply enable partial splenectomies and ligation of the splenic artery which are models for spleen surgery in man

Ten children underwent splenic imaging with heat-denatured red blood cells labeled with technetium-99m (Tc-99m DRBC). The presenting problems included the heterotaxia syndrome, recurrent idiopathic thrombocytopenic purpura following splenectomy, mass in the left posterior hemithorax, and blunt abdominal trauma. In nine patients, the presence or absence of splenic tissue was established. A splenic hematoma was identified in the tenth patient. All patients were initially scanned with Tc-99m sulfur colloid (Tc-99m SC), and were selected for Tc-99m DRBC scintigraphy only after the results of the SC scans failed to establish the clinical problem beyond doubt. The availability of kits containing stannous ions, essential for efficient and stable labeling of red blood cells with Tc-99m and requiring only a small volume of blood, make splenic scintigraphy in children a relatively simple and definitive diagnostic procedure, when identification of splenic tissue is of clinical importance
