BACKGROUND: Leukocytosis and thrombocytosis often follow splenectomy in blunt trauma patients, complicating the postoperative identification of infection. While the platelet count to white blood cell ratio provides diagnostic assistance to discern between expected laboratory alterations and infection, diagnoses such as leukemia are often overlooked. CASE PRESENTATION: A 53-year-old Hispanic male presented with abdominal pain, nausea, tachycardia, and focal peritonitis 4 days after being assaulted and struck multiple times in the abdomen. Initial white blood cell count was 38.4 × 109/L, platelet count was 691 × 109/L, and lipase was 55 U/L. Computed tomography abdomen/pelvis demonstrated a hematoma encasing the distal pancreas and abutting the stomach and colon. Emergent laparotomy revealed a nearly transected pancreas and devascularized colon, necessitating a distal pancreatectomy, splenectomy, and colonic resection with primary anastomosis. Postoperatively, he had a persistently elevated leukocytosis, thrombocytosis, segmented neutrophils, eosinophilia, and basophilia (peak at 70, 2293, 64, 1.1, and 1.2 × 109/L, respectively). Despite sepsis workup, including repeat computed tomography, no source was identified. Hematology/oncology was consulted for concern for hematologic etiology, with genetic testing and bone marrow biopsy performed. The diagnosis of breakpoint cluster-Abelson gene-positive chronic myeloid leukemia was made based on genetic tests, including polymerase chain reaction and fluorescence in situ hybridization analysis, which confirmed the presence of the Philadelphia chromosome. Bone marrow biopsy suggested a chronic phase. The patient was treated with hydroxyurea and transitioned to imatinib. CONCLUSIONS: Thrombocytosis following splenectomy is a common complication and a plate count to white blood cell count ratio   50 × 109/L) and thrombocytosis (> 2000 × 109/L) may suggest something more ominous, including chronic myeloid leukemia , particularly when elevated granulocyte counts are present. Chronic myeloid leukemia workup includes peripheral smear, bone marrow aspiration, and determination of Philadelphia chromosome. Post-splenectomy vaccines are still indicated within 14 days; however, the timing of immunization with cancer treatment must be considered. Tyrosine kinase inhibitors are the first-line therapy and benefits of pretreatment with hydroxyurea for cytoreduction remain under investigation. Additionally, tyrosine kinase inhibitors have been associated with gastrointestinal perforation and impaired wound healing, necessitating heightened attention in patients with a new bowel anastomosis.

Purpose: This study aimed to identify risk factors for rebleeding within 180 days post-discharge in blunt splenic injury patients managed without splenectomy or embolization. Materials and methods: A retrospective analysis was conducted using Taiwan's National Health Insurance Research Database. Adult patients aged ≥ 18 years with blunt splenic injury (ICD-9-CM codes 865.01–865.09) from 2000 to 2012 were included. Patients who died, underwent splenectomy (ICD-9-OP codes 41.5, 41.42,41.43, and 41.95) or transcatheter arterial embolization (TAE) (ICD-9-OP codes 39.79 and 99.29) on the first admission were excluded. The primary endpoint was rebleeding, which was identified if patients underwent splenectomy or TAE at 180 days after discharge. Multivariate logistic regression was used to identify risk factors, which were validated in a separate cohort. Results: Of 6,140 patients, 80 (1.302%) experienced rebleeding within 180 days. Five significant risk factors were identified: age < 54 years (aOR 3.129, p = 0.014), male sex (aOR 2.691, p = 0.010), non-traffic accident-induced injury (aOR 2.459, p = 0.006), ISS ≥ 16 (aOR 2.130, p = 0.021), and congestive heart failure (aOR 6.014, p = 0.006). We generate Delayed Splenic Bleeding System (DSBS). Patients with > 2 points had significantly higher rebleeding rates (risk-identifying cohort: 2.2% vs. 0.6%, OR 3.790, p < 0.001; validation cohort: 2.6% vs. 0.8%, OR 3.129, p = 0.022). Conclusions: Age < 54 years, male, non-traffic accident-induced injury, ISS ≥ 16, and congestive heart failure are risk factors of rebleeding within 180 days after discharge from treating blunt splenic injury without splenectomy or embolization. Despite limitations, this study underscores large-scale data's role in identifying risks which can aid clinicians in prioritizing additional interventions during NOM. [ABSTRACT FROM AUTHOR]

Background: Blunt spleen injuries (BSI) present significant diagnostic and management challenges in trauma care. Current guidelines recommend arterial-phase contrast-enhanced multidetector computed tomography (CT) for a detailed assessment. However, the direct impact of add-on arterial phase CT on clinical outcomes remains unclear. This study investigated the impact of early arterial-phase imaging via multidetector CT on the clinical outcomes of patients with blunt splenic injuries. Methods: A retrospective case-control study was conducted to analyze the data of adult patients with BSI treated at a single institution between 2019 and 2022. Patients were divided based on the CT phase performed: portal vein phase only or add-on arterial phase. Management methods were divided according to the initial treatment intent: nonoperative management observation (NOM-Obs), transarterial embolization (TAE), and splenectomy. NOM failure refers to either NOM-Obs or TAE failure leading to splenectomy. NOM-Obs failure refers to cases initially managed with observation only, but later requiring either TAE or splenectomy. Transarterial embolization (TAE) failure refers to cases initially treated with TAE, but subsequently requiring splenectomy. Inverse probability of treatment weighting (IPTW) was used to balance baseline differences and compare outcomes between the two groups. Results: Of 170 patients assessed, 147 met the inclusion criteria and were divided into two groups: those receiving portal vein phasic-only CT (N = 104) and those receiving add-on arterial phasic CT (N = 43). The overall NOM failure rate was 3.0% (4/132), the NOM-OBS failure rate was 6.7% (4/60), and the TAE failure rate was 4.1% (3/73). After adjusting for covariates using inverse probability of treatment weighting (IPTW), the comparison between the add-on arterial phase and portal phase CT groups revealed similar overall NOM failure rates (3.0% vs. 2.2%, p = 0.721), NOM-OBS failure rates (3.8% vs. 6.2%, p = 0.703), and intra-abdominal bleeding-related mortality rates (4.8% vs. 2.1%, p = 0.335). Among the 43 patients who underwent add-on arterial CT, only one was diagnosed with a tiny pseudoaneurysm (0.7 cm) attributable to the inclusion of the arterial phase. Conclusion: Dual-phase CT within 24 h of presentation offers no added value over single-phase CT in managing blunt splenic injuries in terms of clinical outcomes. [ABSTRACT FROM AUTHOR]

A 22-year-old female was referred to our hospital due to thrombocytopenia and esophagogastric varices (EGV) [LmF2CbRC1, Lg-c,F1RC0], therefore we performed endoscopic variceal ligation. Dynamic abdominal computed tomography showed giant portosystemic shunts (PSSs) from the left gastric vein to the superior vena cava and splenomegaly despite normal hepatic contour. Blood tests showed thrombocytopenia and hypoalbuminemia, but there were no abnormalities in hepatic function. Retrograde hepatic venography and transjugular liver biopsy were subsequently performed in order to further examine liver pathology. These examinations revealed anastomosis between the right and middle hepatic veins, with no features to suggest cirrhosis, therefore diagnosed as idiopathic portal hypertension. Splenectomy was performed for the treatment of hypersplenism with thrombocytopenia. Nine months after undergoing a splenectomy, the patient consulted a cardiologist due to exertional dyspnea with WHO functional class II. Echocardiography revealed a mild dilatated right ventricle (RV) with an estimated systolic pressure of 55 mmHg, consistent with pulmonary hypertension. Right heart catheterization determined an increased mean pulmonary arterial pressure of 40 mmHg and pulmonary vascular resistance of 7.5 wood units, but a normal pulmonary capillary wedge pressure value of 7 mmHg, resulting in the diagnosis of portopulmonary hypertension (PoPH). Administration of oral macitentan 5 mg/day was initiated. Exertional dyspnea and the findings from right heart catheterization were improved with macitentan 10 mg/day. No report exists of PoPH occurring within one year after splenectomy, however we report here a very rare case in which a splenectomy brought about the onset of PoPH. [ABSTRACT FROM AUTHOR]

Introduction and importance: Wandering spleen is a rare condition characterized by the extreme laxity or absence of ligaments that normally secure the organ in its anatomical position in the left upper quadrant. Torsion of a wandering spleen is an uncommon cause of acute abdominal pain and is rarely diagnosed preoperatively. Torsion involving the distal pancreas is even more unusual. Although patient presentations can be atypical, early diagnosis and prompt intervention can lead to successful outcomes. Case presentation: A 40-year-old Black female patient of Amhara ethnicity, from Ethiopia, presented with dull, aching abdominal pain and episodes of vomiting. After initial physiological stabilization and radiologic evaluation, laparotomy was performed, revealing torsion of a wandering spleen with involvement of the pancreatic tail, accompanied by adhesions of the small bowel and omentum. Following the release of adhesions, a splenectomy was performed. The patient was discharged in stable condition and continued to do well during follow-up visits. Conclusion: Despite its rarity and potential for atypical presentations, a high index of suspicion for torsion of a wandering spleen is essential, particularly in patients with risk factors. With prompt diagnosis and timely intervention, patients with this condition can achieve favorable outcomes. [ABSTRACT FROM AUTHOR]

Background/Objectives: Splenectomy leads to a high rate of remission in chronic primary immune thrombocytopenia (ITP), but its unpredictable long-term positive outcomes and that it is a irreversible surgical approach discourage clinicians and patients. The identification of predictors of response may redefine the timing of splenectomy. In this retrospective, multicentric study we aimed to investigate clinical–histological predictors of splenectomy response in ITP patients and provide an easy-to-use score to predict splenectomy response in ITP. Methods: We considered a discovery set (n = 17) and a validation set (n = 30) of adult ITP patients, who underwent splenectomy for refractory disease in three Italian referral centers for ITP. Results: We found that the presence of autoimmune comorbidities, daily steroid dose prior to splenectomy, age at diagnosis and age at splenectomy were significantly associated with the outcome. Variables singly associated with an adverse outcome were combined into a clinical and a clinical–pathological score, allowing us to define a "high-risk" group which accounted for about 80% of the disease relapses observed in this cohort. At the same time, a certain clinical–pathological score indicated a "high-risk" group characterized by significantly poorer outcomes. Results were confirmed in the validation cohort. Conclusions: An integrated set of clinical and histological parameters may predict the response to splenectomy in ITP patients. While these findings provide valuable insights, they were derived from a small cohort of patients and therefore require validation in larger, more diverse populations to ensure their generalizability and robustness.

Laparoscopic distal pancreatectomy is a minimally invasive approach for the surgical treatment of neoplasms in the distal pancreas. This study aimed to compare this approach to the open procedure. A retrospective analysis of a prospectively maintained database of 400 pancreatectomies was performed. The laparoscopic distal pancreatectomy group (LDP) was compared to the open distal pancreatectomy group (ODP). A propensity score matching analysis (PSM) was performed. From 2016 to 2023, 108 distal pancreatectomies were carried out, 19 (17.6%) laparoscopically and 89 (82.4%) openly. The conversion rate was 13.6%. The severe morbidity rates were 28.1% in the ODP group, 47.4% in the LDP group, and 15.8% in the ODP-PSM group. The difference between the latter two was statistically significant (p = 0.034) due to the high rate of Clavien–Dindo grade 3a complications (42.1% versus 10.5%, p = 0.042) in the LDP group. The 90-day mortality rates were 3.3% in the ODP group and 5.3% in the other two groups. The LDP group had a shorter duration of intravenous narcotic analgesia (5 versus 7 days, p = 0.041). There was no difference in the R0 resection or postoperative pancreatic fistula rates. Our attention should be drawn to preventing postoperative complications because the oncological outcomes are already comparable with those of the open procedure, and postoperative pain management is promising.

Background: The anesthetic management of patients with glucagonoma is complicated by a number of factors including glucose fluctuation, characterized necrolytic migratory erythema in oral and pharyngeal, which may lead to an unexpected difficult airway. Case presentation: Herein we describe the anesthetic considerations and management of a 47-year-old adult with glucagonoma, who presented for a laparoscopic splenectomy and distal pancreatectomy procedure. Conclusion: This report details fiberoptic intubation in an adult with glucagonoma and necrolytic migratory erythema. We recommend that this approach be considered in patients with glucagonoma and severe necrolytic migratory erythema undergoing general anesthesia. [ABSTRACT FROM AUTHOR]

Objective: Splenectomy is regularly performed in total and distal pancreatectomy due to technical reasons, lymph node dissection and radicality of the operation. However, the spleen serves as an important organ for competent immune function, and its removal is associated with an increased incidence of cancer and a worse outcome in some cancer entities (Haematologica 99:392–398, 2014; Dis Colon Rectum 51:213–217, 2008; Dis Esophagus 21:334–339, 2008). The impact of splenectomy in pancreatic cancer is not fully resolved (J Am Coll Surg 188:516–521, 1999; J Surg Oncol 119:784–793, 2019). Methods: We therefore compared the outcome of 193 pancreatic cancer patients who underwent total or distal pancreatectomy with (Sp) or without splenectomy (NoSp) between 2015 and 2021 using the StuDoQ|Pancreas registry of the German Society for General and Visceral Surgery. In addition, we integrated our data into the existing literature in a meta-analysis of studies on splenectomy in pancreatic cancer patients. Results: There was no difference between the Sp and NoSp groups regarding histopathological parameters, number of examined or affected lymph nodes, residual tumor status, or postoperative morbidity and mortality. We observed a significantly prolonged survival in pancreatic cancer patients who underwent total pancreatectomy, when a spleen-preserving operation was performed (median survival: 9.6 vs. 17.3 months, p = 0.03). In this group, splenectomy was identified as an independent risk factor for shorter overall survival [HR (95%CI): 2.38 (1.03 – 6.8)]. In a meta-analysis of the existing literature in combination with our data, we confirmed splenectomy as a risk factor for a shorter overall survival in pancreatic cancer patients undergoing total pancreatectomy, distal pancreatectomy, or pancreatic head resection [HR (95%CI): 1.53 (1.11 – 1.95)]. Conclusion: Here, we report on a strong correlations between removal of the spleen and the survival of pancreatic cancer patients undergoing total pancreatectomy. This should encourage pancreatic surgeons to critically assess the role of splenectomy in total pancreatectomy and give rise to further investigations. [ABSTRACT FROM AUTHOR]

Background/aim: This research study was conducted to examine the clinical characteristics and post-splenectomy survival outcomes of patients diagnosed with hepatosplenic T-cell lymphoma (HSTCL). Materials and methods: A total of 10 cases of HSTCL patients admitted to the Hematology Department of Fudan University Affiliated Huadong Hospital between January 2012 and December 2021 were included. In addition, we also included 30 other cases reported from domestic and international sources. All pathological specimens were stained with hematoxylin and eosin (H&E) and immunohistochemistry, with color development using DAB staining. Survival analysis was conducted using Kaplan-Meier curves and log-rank tests. Results: In the 10 HSTCL patients, Epstein-Barr virus (EBV) infection was confirmed. Six patients had died, with 5 of them within 1 year of disease onset. Survival analysis showed poorer prognosis in patients with hemophagocytic syndrome and thrombocytopenia. Patients who underwent splenectomy followed by chemotherapy had a higher median and average survival time compared to those who only received chemotherapy. The study included a total of 40 HSTCL patients, with 29 males and 11 females, and an average age of onset at 42.3 years. All patients presented with fever, with some exhibiting emaciation and/or hemophagocytic syndrome. Splenomegaly, hepatomegaly, lymphadenopathy, and bone marrow involvement were found in the patients. Common laboratory findings included leukopenia, anemia, and thrombocytopenia. All patients exhibited elevated ferritin levels and decreased blood calcium levels. Conclusion: Those patients suffering from hemophagocytic syndrome at the onset of this disease face greater treatment-related difficulties and a higher risk of mortality. Combined chemotherapy after splenectomy may improve HSTCL patient survival. [ABSTRACT FROM AUTHOR]

The objectives of this study were to evaluate the risk and predictive factors of splenic malignancy and hemangiosarcoma in dogs undergoing splenectomy at a surgical specialty clinic. Medical records, hematologic results, surgical reports, and histopathologic results from 182 dogs that underwent splenectomy for the treatment of splenic masses or nodules were reviewed retrospectively. The majority of dogs (57.7%) had benign splenic diagnoses with no malignancy. Hemangiosarcoma was diagnosed in 32.4% of the dogs. A final multivariable model indicated that thrombocytopenia, anemia, and a smaller diameter of the largest splenic nodule were risk factors for hemangiosarcoma (P<0.001), and hemoperitoneum (P = 0.01) was an additional risk factor when nodule diameter was not evaluated. There were 91 dogs that had hemoperitoneum, and 60.4% of those dogs had malignant splenic lesions. Of the 33 dogs that underwent a splenectomy for incidentally identified splenic lesions, 93.9% had benign splenic lesions. Breed size was not a significant predictor of splenic malignancy risk; however, all 6 of the German shepherds included in the study had a hemangiosarcoma diagnosis. Overall prevalence of splenic malignancy including HSA may be overestimated in some canine populations. [ABSTRACT FROM AUTHOR]

Background: Advanced laparoscopic solid organ surgery is now possible with the use of LigaSure and the Harmonic scalpel, which drastically cut down on operating time and blood loss. This work aimed to compare the effectiveness of LigaSure or Ultracision in Laparoscopic Splenectomy (LS) regarding dissection, operative time, and blood loss. Methods: in this randomized prospective clinical trial 36 patient candidates for LS were randomized into two groups (18 patients in each group): in Group A LS was performed and in Group B Harmonic was performed. Intra-operative measures/difficulties (Operative time, occurrence of bleeding/blood loss, presence of accessory spleen, need for intraoperative blood transfusion) were assessed in addition to postoperative hospital stay. Results: In the LigaSure group, no intraoperative encountered difficulties (0%), while in the Harmonic group, 5 cases (27.78%) experienced such issues, representing a significant increase (p = 0.0152). The LigaSure group had statistically shorter operation time compared to the harmonic group (124.94 ± 16.24 vs. 149.28 ± 12.87, p < 0.0001). Intraoperative blood loss was also statistically lower in the LigaSure group (81.67 ± 19.22 vs. 124.17 ± 14.55, p < 0.001), the LigaSure patients required significantly fewer blood transfusions intraoperatively (0% vs. 22.22%, p = 0.1039). Postoperative CBC analysis showed a significant decrease in Hb levels in the Harmonic group (9.78 ± 0.34 g/dl) compared to the LigaSure group (10.09 ± 0.34 g/dl) (p = 0.0121). Conclusion: When it comes to benign hematological problems, LS should always be the primary option for spleen removal. LigaSure and Ultracision both could offer important advantages in laparoscopy. Using LigaSure in LS reduced the operative time, blood loss, and the need for intraoperative blood transfusion. [ABSTRACT FROM AUTHOR]

Simple Summary: With the advent of effective chemotherapy, conversion surgery (CS) has been performed in patients who have responded to pretreatment, even for pancreatic cancer diagnosed as unresectable (UR) at the time of initial diagnosis. In CS, major arterial resection and reconstruction are necessary for complete radical resection. Many patients who require celiac axis (CA) resection combined with reconstruction have large tumors, poor findings of spread to surrounding tissues, and tumor invasion near the Abdominal Aorta; therefore, ingenuity is required for a safe resection. Furthermore, CA resection combined with reconstruction after specimen removal requires skills and experience in vascular surgery, such as selecting the arterial anastomosis site and the vessels to be used for bypass. We discuss the key points for safely performing pancreatectomy with CA resection combined with reconstruction, divided into resection (how to create "golden view") and arterial reconstruction. Background: With the advent of effective chemotherapy, conversion surgery (CS) has been performed in patients who have responded to pretreatment, even for pancreatic cancer diagnosed as unresectable (UR) at the time of initial diagnosis. In CS, major arterial resection and reconstruction are necessary for complete radical resection. Methods: We discuss the key points for safely performing pancreatectomy with celiac axis (CA) resection combined with reconstruction, divided into resection and arterial reconstruction. The possibility of safe pancreatectomy concurrent with CA resection and reconstruction depends on the ability to create a "golden view" that provides an unimpaired view of the Abdominal Aorta, CA, Superior Mesenteric Artery, Inferior Vena Cava, and left renal vein from the ventral side. Pancreatectomy concurrent with CA resection requires arterial reconstruction. Postoperatively, arterial blood flow must be maintained. To achieve this, tension-free and short bypass should be observed. Results: From 2014 to 2024, sixteen URLA patients underwent CS, requiring major artery en bloc resection after pretreatment. We performed DP-CAR in eight patients, gastrectomy-distal pancreatectomy-splenectomy (Appleby procedure) procedure in one patient, PD-CHAR in two patients, PD-CAR in two patients, TP-CAR(spleen preserving) in one patient, and TP-CAR+TG in two patients. In total, five patients required surgery with CA reconstruction. Histopathologically, four of the five patients had T4 pancreatic cancer. The R0 surgical rate was 80%. Complication of Clavien–Dindo IIIa or higher was observed in one patient. There were no deaths. Conclusions: Parallel to the determination of pretreatment, surgeons must be prepared to safely and reliably perform pancreatectomies that require concurrent major arterial resection and reconstruction.

Kasabach–Merritt syndrome (KMS) is a coagulopathy characterized by thrombocytopenia and hypofibrinogenemia associated with large vascular tumors. KMS can lead to disseminated intravascular coagulation which, if not treated promptly, can be life-threatening. There are few reported cases of this syndrome and its evolution in pregnant women.

Introduction: While laparoscopic splenectomy (LS) has been widely used in benign splenic tumor, more concerns have been raised for postoperatively short-term and long-term complications. Laparoscopic partial splenectomy (LPS) is a surgical option, to preserve splenic function, and reduce postoperative complications. The aim of our study was to retrospectively identify the safety and feasibility of LPS compared with LS in patients with splenic benign tumor. Materials and methods: From 2014 to 2024, a total of 165 patients diagnosed with occupational splenic lesions underwent splenectomy, of whom 87 underwent LPS and 78 underwent LS. We compare the perioperative parameters and long term follow up between these two groups. Results: The etiology of splenic space-occupying lesions was nonparasitic splenic cysts, followed by splenic lymphangioma and splenic hemangioma. Of the patients with LPS, 55 underwent conventional surgery with blockage of the splenic arterial branch and resection along the ischemic line (RAIL), and 32 underwent with our modified total splenic blood supply blockade followed by resection alone the tumor edge (RATE). The tumor size, the operative time and estimated blood loss were comparable between the LPS and LS groups. One patient developed abnormal signs during the LPS procedure and was promptly referred for LS. The LPS group had fewer pancreatic leakage, incision infection, and pulmonary infection. As for different vascular types, patients with LS under all branches of the splenic artery had a longer time to resume postoperative feeding. As for the comparison of RAIL and RATE, estimated blood and operative time were significantly reduced in patients receiving RATE. Postoperative complications were the same in patients underwent each surgical procedures. Conclusion: LPS is a viable approach for patients with splenic benign tumor. We introduce the tumor artery supply types to indicate the resection region. Our RATE technique has proven to be clinically effective and safety. [ABSTRACT FROM AUTHOR]

Infective endocarditis(IE) has a low incidence, but it remains a serious disease with high mortality rates. Only 5 % of these patients will develop a splenic abscess, and the number of patients that have IE and a splenic abscess requiring surgery is low. The current guidelines recommend that splenectomy should be performed prior to valve replacement, but there is no strong evidence to support this statement and no evidence to clearly endorse the order in which the surgical interventions should be performed. The objective of this review and case series is to establish the proper treatment strategy, to assess the adequate order of the surgical interventions and to clarify the role of percutaneous drainage in the management of these patients. All patients with infective endocarditis and splenic abscess who underwent surgery in our institution, between January 2008 and December 2020 were included in this study, excluding patients which had cardiac device related endocarditis. Literature review on the matter included a number of 30 studies which were selected from the PubMed database. Assessing the literature and case series no reinfection was reported for simultaneously performing splenectomy(S) and valvular surgery(VS) nor for VS followed by S. Percutaneous drainage of the splenic abscesses is a feasible solution as definitive therapy in high-risk patients or as bridge therapy. Additional studies are needed, even though they are difficult to conduct, therefore a national/international infectious endocarditis register may be of use to clarify these challenges. • Infective endocarditis is rare, deadly, and requires a multidisciplinary team. • Only 5 % of these patients develop splenic abscesses, with few needing specific surgery. • Percutaneous drainage is viable for high-risk patients as definitive or bridge therapy. • Guidelines-splenectomy before valvular surgery; studies: no reinfection either way. • A national/international registry may help clarify challenges in managing endocarditis.

Background: Non-operative management of hemodynamically stable patients with splenic trauma has been recommended for more than 25 years, but in practice embolization and/or splenectomy (intervention) is often needed within the first 30 days. Identifying the risk factors associated with the need for intervention could support more individualized decision-making. Methods: We used data from the SPLASH randomized clinical trial, a comparison of outcomes of surveillance or embolization. 140 patients were randomized, 133 retained in the study (embolization n = 66; surveillance n = 67) and 103 screened and registered in the non-inclusion register. Multivariate Cox proportional hazards models with time-varying covariates were used to identify risk factors contributing to embolization and/or splenectomy within 30 days after initiating surveillance only for splenic trauma. Results: 123 patients (median age, 30 [23; 48] years; 91 (74%) male) initially received non-operative management. At the day-30 visit, 34 (27.6%) patients had undergone an intervention (31 (25.2%) delayed embolization and 4 (3.3%) splenectomy). Multivariate analysis identified patients with OIS grade 4 or 5 splenic trauma (HR = 4.51 [2.06–9.88]) and (HR = 34.5 [6.84–174]); respectively) and splenic complications: arterial leak (HR = 1.80 [1.45–2.24]), pseudoaneurysm (HR = 1.22 [1.06–1.40]) and pseudocyst (HR = 1.41 [1.21–1.64]) to be independently associated with increased risk of need for an intervention within 30 days of initiating surveillance. Conclusions: Our study shows that more than 1 in 4 patients who received non-operative management needed embolization or splenectomy by day 30. Arterial leak, pseudoaneurysm, pseudocyst, and OIS grade 4 or 5 were independent risk factors linked to the need for an intervention. TRIAL REGISTRATION: clinicaltrials.gov Identifier NCT 02021396.

Although postoperative portal vein thrombosis (PVT) is a frequent complication of splenectomy, few studies have examined PVT after simultaneous hepatectomy and splenectomy (HS). The aim of this study was to clarify the risk factors for and characteristics of PVT after HS. This retrospective observational study included 102 patients, including 76 with liver cirrhosis (LC) and 26 without, who underwent HS between April 2004 and April 2021. The incidence and location of postoperative PVT detected on contrast-enhanced CT 1 week after surgery were analyzed. In addition, pre- and intraoperative parameters were compared between patients with postoperative PVT and those without in order to determine risk factors for PVT after HS. Among the 102 patients, 29 (28.4 %), including 32.9 % with LC and 15.4 % without LC, developed PVT after surgery. Among the 29 patients with PVT, 21 (72.4 %), 4 (13.8 %), and 4 (13.8 %) developed thrombus in the intrahepatic portal vein only, extrahepatic portal vein only, and both the extra- and intrahepatic portal veins, respectively. Multivariable analysis showed that preoperative splenic vein dilatation was an independent risk factor for PVT after HS (odds ratio: 1.53, 95 % confidence interval: 1.156–2.026, P = 0.003). Our results suggest that splenic vein dilatation is an independent risk factor for PVT after simultaneous HS, and that PVT after HS occurs more frequently in the intrahepatic portal vein. After HS for cases with dilated splenic veins, we should pay particular attention to the PVT development in the intrahepatic portal vein regardless of the type of liver resection.

Purpose of Review: Allogeneic hematopoietic cell transplantation is the only potentially curative treatment for myelofibrosis. This review discusses issues not well-covered by existing guidelines: timing of transplant, pre-transplant spleen management and alternative donors; providing our approach to these situations. Recent Findings: Research continues to allow better identification, by better risk stratification and advances in understanding likelihood of durable JAKi response, which patients are likely to derive benefit from upfront transplant versus those for whom delayed transplant may be more appropriate. Several options of JAKi therapy provide a non-surgical option for pre-HCT splenomegaly management, allowing some patients to avoid risks associated with splenectomy. Recent years have also seen a sharp spike in haploidentical donor transplants, along with narrowing of the gap in outcomes between donor types. Summary: Continuous enrollment in prospective studies or well-designed registries is required to generate the high-quality data needed to develop better decision tools for these scenarios.

Portal inflow modulation has become standard practice in many transplant centers performing living donor liver transplantation. This is believed to counteract the deleterious effects of excess portal flow into a small-for-size graft. A splenectomy negates the contribution of the splenic vein flow completely and thereby substantially reduces portal inflow. Although it has been adopted as a standard strategy by many Japanese centers for inflow modulation, especially while using left hemiliver grafts, there is justifiable apprehension about its usage due to potential increases in morbidity. Described here is a splenectomy performed while using a modified right hemiliver graft with a graft to recipient weight ratio of 0.49.

Background: Although postoperative portal vein thrombosis (PVT) is a frequent complication of splenectomy, few studies have examined PVT after simultaneous hepatectomy and splenectomy (HS). The aim of this study was to clarify the risk factors for and characteristics of PVT after HS. Methods: This retrospective observational study included 102 patients, including 76 with liver cirrhosis (LC) and 26 without, who underwent HS between April 2004 and April 2021. The incidence and location of postoperative PVT detected on contrast-enhanced CT 1 week after surgery were analyzed. In addition, pre- and intraoperative parameters were compared between patients with postoperative PVT and those without in order to determine risk factors for PVT after HS. Results: Among the 102 patients, 29 (28.4 %), including 32.9 % with LC and 15.4 % without LC, developed PVT after surgery. Among the 29 patients with PVT, 21 (72.4 %), 4 (13.8 %), and 4 (13.8 %) developed thrombus in the intrahepatic portal vein only, extrahepatic portal vein only, and both the extra- and intrahepatic portal veins, respectively. Multivariable analysis showed that preoperative splenic vein dilatation was an independent risk factor for PVT after HS (odds ratio: 1.53, 95 % confidence interval: 1.156–2.026, P = 0.003). Conclusion: Our results suggest that splenic vein dilatation is an independent risk factor for PVT after simultaneous HS, and that PVT after HS occurs more frequently in the intrahepatic portal vein. After HS for cases with dilated splenic veins, we should pay particular attention to the PVT development in the intrahepatic portal vein regardless of the type of liver resection.

Dogs that had splenectomy are predisposed to fatal thrombotic conditions, and thrombocytosis is a risk factor for post-splenectomy hypercoagulability. However, in veterinary medicine, there are no specific therapeutic approaches for managing this hypercoagulability. This study aimed to determine the preventive effect of clopidogrel on post-operative hypercoagulability during the first 2 weeks post-splenectomy in dogs with splenic masses. This study included 12 dogs that had splenectomy. Seven dogs received no treatment (group A), and five were treated with clopidogrel (group B). Clopidogrel was loaded at 10 mg/kg on day 2 and continued at 2 mg/kg until day 14. Blood samples were collected on the day of surgery and 2, 7, and 14 days after splenectomy in both groups. In group B, thromboelastography (TEG) was performed on the same days. In group A, there was significant elevation of platelet counts on days 7 (p = 0.007) and 14 (p = 0.001) compared to day 0. In group B, the platelet counts were significantly elevated on day 7 (p = 0.032) but no significant difference was found on day 14 compared to day 0. Platelet counts on day 14 were significantly higher in group A than in group B (p = 0.03). The lower platelet counts were correlated with alterations in TEG parameters, and no significant differences were found in the K and α-angle values at all postoperative assessment points compared to day 0. Our study suggests that clopidogrel may reduce post-operative thrombocytosis and hypercoagulability in dogs that undergo splenectomy for splenic masses.

The clinical course of patients with chronic hemolytic anemia can be complicated by the development of splenomegaly and consequent hypersplenism. This may warrant management by medical or surgical methods. Furthermore, in some patients, splenic manipulation may be warranted in the absence of hypersplenism, spleen being the primary site of red cell destruction. Wherever possible, splenectomy is avoided or deferred in view of the life-long risks of infection and thrombosis associated with this procedure. Optimal management in hemolytic anemia, therefore, incorporates prevention of hypersplenism as one of the key treatment goals.

A 41-year-old male with a history of tobacco and alcohol use presented to our clinic for a follow up of an incidentally diagnosed splenic mass. The patient was sent for further diagnostic evaluation, and computed tomography showed a large splenic mass with heterogenous enhancement raising concern for neoplasm. Due to the uncertain nature of the splenic lesion and high complication rate of percutaneous splenic biopsy, a splenectomy was performed. The specimen was sent to pathology, and the report favored neoplasm but was inconclusive. The samples were sent to another institution for a consult, where the patient's spleen was determined to be the result of a previously suffered hemorrhagic infarct. This case demonstrates the difficulty of diagnosing splenic lesions using diagnostic imaging and the discrepancy that may occur between radiology and pathology assessments. In the setting of uncertain pathology, the removal of what might be a functional spleen is often preferred over a percutaneous biopsy due to concerns of intraabdominal bleeding and tumor dissemination.

Background: There is a lack of literature on the role of splenectomy in hemolytic anemias due to glucose-6-phosphate isomerase (GPI) deficiency. GPI deficiency is a rare red blood cell (RBC) enzymopathy of the glycolytic pathway. Most present with severe disease requiring frequent transfusions. In this study, we report the effect of splenectomy in the world's largest cohort of GPI deficiency patients. The study aimed to describe the clinical, mutational, and laboratory parameters of patients with GPI deficiency. A comparison of the transfusion requirement pre- and post-splenectomy is also included. Material and methods: The ambispective study was performed from 2017 to 2023. Patients with congenital non-spherocytic hemolytic anemia (CNSHA) were screened for GPI deficiency. Detailed history, including demographic, clinical data, and transfusion details, were noted. Hematological parameters and RBC enzyme activity were estimated using spectrophotometry. The genetic study was done using restriction fragment length polymorphism, and confirmation was obtained through Sanger's sequencing. Patients were followed up after splenectomy. Results: Eighteen patients were diagnosed with GPI deficiency. About 3/4th (14/18; 77.7 %) had significant hepatosplenomegaly. Median serum ferritin levels were 890 ng/ml. Seven patients were on oral iron chelation. The nutritional status assessed as per the Indian Academy of Pediatrics growth charts revealed significant growth retardation. All the patients had severe anemia (mean Hb: 6.4 g/dl) and macrocytosis (mean MCV: 129.2 fl). Laboratory features of hemolysis were evident with reticulocytosis, raised serum lactate dehydrogenase, and indirect bilirubin. The mean GPI enzyme activity was 28.75 IU/g Hb.Ten (55.5 %) patients underwent splenectomy at a median age of 7 years. Five remain transfusion-free post-splenectomy at a median follow-up of 54 months. Other 5 had a significant reduction in transfusion requirement post-splenectomy (p A(p.Arg347His) homozygous mutation. Conclusion: The study demonstrates the benefit of splenectomy in patients with GPI deficiency.

Abstract Background Leptospirosis poses a diagnostic challenge owing to its wide array of symptoms, ranging from asymptomatic cases and febrile syndromes to severe disease with a high mortality rate. Risk factors are associated with exposure and the immune response, particularly in immunosuppressed patients. Case presentation A clinical case involving a 49-year-old patient with a history of splenectomy and no immunization schedule. The patient presented to the emergency room with non-specific symptoms, primarily myalgias, arthralgias, and emesis, initially suggestive of a viral infection. However, there was a rapid progression to hypoxemic respiratory failure, requiring invasive ventilatory support. Given the immune status due to spleen absence, antibiotic treatment with meropenem and linezolid was promptly initiated, to mitigate the risk of post-splenectomy sepsis. During antibiotic administration, the patient experienced febrile episodes, accompanied by chills, myalgias, and emesis, which gradually decreased in both duration and intensity. Ultimately, the patient exhibited satisfactory progress, successfully underwent extubation, and completed a 7-day antibiotic course. Final reports confirmed positive IgM for Leptospira. Conclusion Leptospirosis is a global zoonotic disease, displaying a diverse array of manifestations; recognized as a potential cause of undifferentiated fever, often confused with other prevalent tropical infections. The imperative to consider this diagnosis extends beyond the general population to encompass individuals in states of altered immunity. Recognizing and addressing leptospirosis in at-risk populations is crucial, as it can significantly impact the prompt initiation of treatment and, consequently, influence associated mortality rates.

Abstract Background Splenectomy indications are well documented; however, several infectious complications and potentially life-threatening conditions could arise after splenectomy. We aim to describe a 20-year single-center experience of postoperative outcomes after splenectomy and perform a subgroup analysis according to approach and surgical setting with a 30-day, 90-day, and 1-year follow-up. Study design A retrospective cohort study was conducted between 2003 and 2023. We included all patients aged 18 years and older who underwent splenectomy. A description of clinical and operative variables with infectious outcomes was performed. Subgroup analyses were performed between open or laparoscopic approach and surgical setting. Results A total of 134 patients were included. Female patients constituted 52.99% (n = 71) of cases, with a mean age of 51.01 ± 20.79 years. The most frequent surgical indication for splenectomy was trauma in 31.34% (n = 42), and a laparoscopic approach was indicated in 41.79% (n = 56). Overwhelming post-splenectomy syndrome (OPSI) was evidenced in 2.24% (n = 3) of the population. Surgical characteristics such as operative time, intraoperative blood loss, and intensive care requirement and unit length of stay were higher in open and trauma patients. Conclusion Our data describe the demographic, clinical and operative characteristics of patients undergoing splenectomy in Colombia, providing a solid basis for future research. The results obtained on overwhelming postsplenectomy syndrome (OPSI) and postoperative complications are comparable with those reported in the international literature, reinforcing the validity of our findings. Further prospective studies in this population are needed to optimize management strategies and improve clinical outcomes, particularly in higher risk subgroups.

Portal inflow modulation has become standard practice in many transplant centers performing living donor liver transplantation. This is believed to counteract the deleterious effects of excess portal flow into a small-for-size graft. A splenectomy negates the contribution of the splenic vein flow completely and thereby substantially reduces portal inflow. Although it has been adopted as a standard strategy by many Japanese centers for inflow modulation, especially while using left hemiliver grafts, there is justifiable apprehension about its usage due to potential increases in morbidity. Described here is a splenectomy performed while using a modified right hemiliver graft with a graft to recipient weight ratio of 0.49. The challenges in decision making and reasons regarding how such a small graft might have worked without manifestations of small-for-size/flow syndrome are discussed.

Abstract Background Leukocytosis and thrombocytosis often follow splenectomy in blunt trauma patients, complicating the postoperative identification of infection. While the platelet count to white blood cell ratio provides diagnostic assistance to discern between expected laboratory alterations and infection, diagnoses such as leukemia are often overlooked. Case presentation A 53-year-old Hispanic male presented with abdominal pain, nausea, tachycardia, and focal peritonitis 4 days after being assaulted and struck multiple times in the abdomen. Initial white blood cell count was 38.4 × 109/L, platelet count was 691 × 109/L, and lipase was 55 U/L. Computed tomography abdomen/pelvis demonstrated a hematoma encasing the distal pancreas and abutting the stomach and colon. Emergent laparotomy revealed a nearly transected pancreas and devascularized colon, necessitating a distal pancreatectomy, splenectomy, and colonic resection with primary anastomosis. Postoperatively, he had a persistently elevated leukocytosis, thrombocytosis, segmented neutrophils, eosinophilia, and basophilia (peak at 70, 2293, 64, 1.1, and 1.2 × 109/L, respectively). Despite sepsis workup, including repeat computed tomography, no source was identified. Hematology/oncology was consulted for concern for hematologic etiology, with genetic testing and bone marrow biopsy performed. The diagnosis of breakpoint cluster–Abelson gene-positive chronic myeloid leukemia was made based on genetic tests, including polymerase chain reaction and fluorescence in situ hybridization analysis, which confirmed the presence of the Philadelphia chromosome. Bone marrow biopsy suggested a chronic phase. The patient was treated with hydroxyurea and transitioned to imatinib. Conclusions Thrombocytosis following splenectomy is a common complication and a plate count to white blood cell count ratio 50 × 109/L) and thrombocytosis (> 2000 × 109/L) may suggest something more ominous, including chronic myeloid leukemia , particularly when elevated granulocyte counts are present. Chronic myeloid leukemia workup includes peripheral smear, bone marrow aspiration, and determination of Philadelphia chromosome. Post-splenectomy vaccines are still indicated within 14 days; however, the timing of immunization with cancer treatment must be considered. Tyrosine kinase inhibitors are the first-line therapy and benefits of pretreatment with hydroxyurea for cytoreduction remain under investigation. Additionally, tyrosine kinase inhibitors have been associated with gastrointestinal perforation and impaired wound healing, necessitating heightened attention in patients with a new bowel anastomosis.

Abstract Background Hepatic venous pressure gradient (HVPG) is considered the gold standard for diagnosing portal hypertension (PHT). Laparoscopic splenectomy plus esophagogastric devascularization (LSED) is an important surgery for treating PHT. However, the variation trend of HVPG after surgery is not clear. Moreover, whether HVPG can provide precise prognostic information for patients undergoing surgery remains to be further studied. This study aimed to investigate the independent prognostic value of HVPG in LSED. Methods From January 2016 to March 2023, 135 patients with PHT underwent LSED at our hospital were retrospectively evaluated. We analyzed the correlations between clinical indicators and history of upper gastrointestinal bleeding (UGIB). Among them, 57 patients remeasured postoperative HVPG. We further investigated the postoperative alterations of HVPG and correlative factors, as well as the relationship between the HVPG and postoperative UGIB. Results In this study, we found that 94 patients with preoperative UGIB (16.27 ± 5.73 mmHg) had a higher baseline HVPG than the other 41 patients without (14.02 ± 5.90 mmHg) (p = 0.04). The mean postoperative HVPG significantly decreased (-3.57 ± 8.09 mmHg, p = 0.001) compared to the baseline, and 66% of patients (38/57) experienced a decreased HVPG-response after surgery. The baseline HVPG and preoperative CTP class B were associated with the decreased HVPG-response (p20% from baseline exhibited better recurrent hemorrhage-free survival rates than those without (log-rank, p = 0.013). Conclusion We found that LSED led to a significantly decreased HVPG, and patients with postoperative HVPG decreased >20% obtained better UGIB-free survival benefits than those without.

Abstract Objective The relationship between lymphocyte-associated inflammatory indices and portal vein thrombosis (PVT) following splenectomy combined with esophagogastric devascularization (SED) is currently unclear. This study aims to investigate the association between these inflammatory indices and PVT, and to develop a nomogram based on these indices to predict the risk of PVT after SED, providing an early warning tool for clinical practice. Methods We conducted a retrospective analysis of clinical data from 131 cirrhotic patients who underwent SED at Lanzhou University’s Second Hospital between January 2014 and January 2024. Independent risk factors for PVT were identified through univariate and multivariate logistic regression analyses, and the best variables were selected using the Akaike Information Criterion (AIC) to construct the nomogram. The model’s predictive performance was assessed through receiver operating characteristic (ROC), calibration, decision, and clinical impact curves, with bootstrap resampling used for internal validation. Results The final model incorporated five variables: splenic vein diameter (SVD), D-Dimer, platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and red cell distribution width-to-lymphocyte ratio (RLR), achieving an area under the curve (AUC) of 0.807, demonstrating high predictive accuracy. Calibration and decision curves demonstrated good calibration and significant clinical benefits. The model exhibited good stability through internal validation. Conclusion The nomogram model based on lymphocyte-associated inflammatory indices effectively predicts the risk of portal vein thrombosis after SED, demonstrating high accuracy and clinical utility. Further validation in larger, multicenter studies is needed.

Immune thrombocytopaenia (ITP) is the most common cause of acquired thrombocytopaenia diagnosed in paediatric patients. It is described as an isolated thrombocytopaenia without other factors, which may cause a decrease in platelets. Therefore, the diagnosis is of exclusion. Over the last few years, its management has significantly developed, and a paradigm switch in second-line treatment is being observed. Currently, thrombopoietin receptor agonists (TPO-RA) are available in Poland, which reduce the need for splenectomy in affected patients. The use of thrombopoietin receptor agonists has also provoked a change in definitions, especially concerning refractory ITP. This review focuses on an overview of currently recommended diagnostics and treatment of ITP, ongoing research concerning genetic predisposition, the use of TPO-RA, other immunosuppressive agents, and the role of splenectomy. We summarise congenital thrombocytopaenic disorders, which are the most often mistaken as ITP and need to be considered in the differential diagnosis.

AIM OF THE STUDY. To investigate the clinical and functional outcomes of autosplenotransplantation in cases of spleen injuries, and to establish its effectiveness in clinical practice. MATERIAL AND METHODS. Using the databases “e-library” and “PubMed”, a thorough review of national and international literature on autosplenotransplantation in patients with traumatic splenic injury was performed. RESULTS. This study analyzes literature sources to describe the technical aspects of autosplenotransplantation. The immediate outcomes of this operation show a low incidence of postoperative complications and good graft survival. In addition, this study presents the indications and contraindications of autosplenotransplantation. Comparing autosplenotransplantation to splenectomy, functional results indicate the best indices of humoral and cellular immunity and hemocoagulation. In the published literature, the functional activity indices of the transplant were comparable to those of healthy individuals with the functioning spleen. However, the studies yielding these results were conducted on small patient samples, limiting the reliability of the conclusions drawn. CONCLUSION. Autosplenotransplantation appears to be the only viable option for preserving the function of the lost spleen in patients with traumatic splenic injury who, for various reasons, cannot receive organ-preserving treatment. Large randomized studies are needed to assess functional results of the operation and, particularly, the immunological function of the transplant.

The splenic localization of hydatid cysts is extremely rare. A 50-year-old obese female who consults with a painful and febrile syndrome of the right hypochondrium. Abdominal ultrasound and a CT scan computed tomography revealed a complete situs inversus, a mass of the right hypochondrium measuring 152 mm with membrane detachment, and infiltration of the surrounding fat, evoking a type II complicated splenic hydatic cyst. The patient was operated on in an emergency via midline laparotomy. Exploration revealed situs inversus, an angiant cyst of the spleen. Exposition of the splenic pedicle is difficult. The samples were then infected. Total splenectomy was performed. The postoperative period was unproblematic, and the patient was discharged with antibiotic and antiparasitic treatment and habitual vaccination.

Aim Methods Results Conclusions Primary splenic pregnancy is a rare form of extratubal ectopic pregnancy, frequently associated with life‐threatening abdominal bleeding, with only 51 cases reported in the worldwide literature. The aim of this work, through the proposal of its own index case, is to identify the fundamental steps of the diagnostic process, crucial to reduce the mortality rate, while evaluating the available therapeutic options, through a review of the literature, particularly the more conservative ones, to avoid splenectomy.We present the case of a 22‐year‐old woman, showing her diagnostic‐therapeutic pathway. We searched Pubmed and other sources for all publications in English and all available non‐English literature, including historical publications, on this rare topic, to identify the best treatment for these patients. We classified each article by clinical onset, diagnostic and therapeutic strategy, and histological findings, if available.We reviewed all the 43 cases available in the English‐language literature (plus another paper in German), finding that 72.7% of patients presented in an emergency setting. Seventy‐five percent of patients required splenectomy, 6.8% received pharmacological‐only therapy, 11.3% received arterial embolization before definitive treatment. The other ones received non‐radical surgical treatment.Primary splenic pregnancy presents challenging diagnostic and therapeutic features. Treatment options (pharmacological, interventional, and/or surgical) should be tailored based on the clinical presentation and hemodynamic status of the patient. Our work would like to stimulate the validation of evidence‐based therapeutic strategies validated by clinical experience. [ABSTRACT FROM AUTHOR]
