Laparoscopic radical antegrade modular pancreatosplenectomy (RAMPS) for adenocarcinoma of the body and tail of the pancreas - technical considerations with analysis of surgical outcomes.

PURPOSE: The aim of this study was to establish whether laparoscopic RAMPS (L-RAMPS) is a safe procedure with better oncological outcomes compared to laparoscopic distal pancreatectomy (LDP) with splenectomy among patients with distal pancreatic ductal adenocarcinoma (PDAC). METHODS: This is a retrospective study performed on consecutive patients who underwent L-RAMPS and LDP with splenectomy for resectable or borderline resectable PDAC of the body and tail. In this paper, we presented our technique of laparoscopic RAMPS and analyzed intraoperative and perioperative complications, oncological efficacy, and long-term survival. RESULTS: The study included 12 patients in the L-RAMPS group and 13 patients in the LDP with splenectomy. L-RAMPS was associated with significantly higher rates of R0 resection (91.7% vs. 69.2%, p = 0.027). There were no differences between the L-RAMPS and LDP with splenectomy groups in intraoperative blood loss (400 mL vs 400 mL, p = 0.783) and median operative time (250 min vs 220 min, p = 0.785). No differences were found in terms of perioperative complications, including the incidence of pancreatic fistula. CONCLUSION: Laparoscopic RAMPS is a feasible and safe procedure. It provides higher radicality as compared with LDP with splenectomy, without increasing the risk of complications. Further studies are necessary to evaluate long-term outcomes.

Temporal trends of splenectomy in pediatric hospitalizations with hereditary spherocytosis from 2000 to 2019: A national survey.

BACKGROUND: Total and partial splenectomy are used in pediatric patients with hereditary spherocytosis to resolve anemia and hemolytic complications. PROCEDURE: Data from the Healthcare Cost and Utilization Project's Kid's Inpatient Database was used to profile and describe temporal trends in pediatric (≤18 years) hospital admissions in the United States from 2000 to 2019 data release years. Survey sampling methods were used to produce national estimates. RESULTS: From 2000 to 2019, the use of splenectomy declined overall, from 427 to 206 weighted procedures (difference = 222, 95% confidence interval [CI]: 124-320; p < .0001); the risk of undergoing splenectomy during admission also declined from 56.7% to 38.7% (risk difference = 17.9 percentage points [p.p.], 95% CI: 9.7-26.1; p < .0001). Total splenectomy was mostly used. Age at time of splenectomy increased 10.2 years (difference = 1.6 years, 95% CI: 0.6-2.7; p = .0018). The risk of splenectomy increased with age until 10 years, then leveled off until 18 years. The proportion of children aged ≤5 years undergoing splenectomy decreased from 27.7% to 11.2% in 2019 (risk difference: 16.5 p.p., 95% CI: 7.3-25.7; p = .0004). The strongest clinical predictors of splenectomy, adjusting for patient- and hospital-level characteristics, were a co-diagnosis of symptomatic cholelithiasis (adjusted odds ratio [aOR] = 3.18, 95% CI: 1.92-5.28; p < .0001) and splenomegaly or hypersplenism (aOR = 2.52, 95% CI: 1.74-3.65; p < .0001). Risk of splenectomy with splenomegaly or hypersplenism increased over time. CONCLUSION: Splenectomy was delayed until age greater than 10 years. Older age, co-diagnosis with splenomegaly or hypersplenism, or symptomatic cholelithiasis were strongest clinical predictors of splenectomy. Conservative management of hereditary spherocytosis appears to be more common.

Robotic-assisted versus laparoscopic splenectomy in children: a costeffectiveness study.

Laparoscopic elective splenectomy is considered as a safe surgical treatment of spleen non-traumatic blood disorders. However, robotic assisted splenectomy is becoming a promising alternative, although there are scarce studies in pediatric patients. Our aim is to compare the effectiveness and associated costs of both procedures in children. A single-institution retrospective study was performed among consecutive children undergoing splenectomy between 2004 and 2021, who were divided according to the surgical approach: LAS group (laparoscopic splenectomy) and RAS group (robotic assisted splenectomy). Demographics, clinical features, intraoperative blood loss, surgery time, length of hospital stay (LOS), postoperative complications, need for postoperative blood transfusion, readmission rate and economic data were compared. A total of 84 patients were included (23 LAS group; 61 RAS group), without demographic or clinical differences between them. RAS patients presented lower intraoperative blood loss (42 ± 15 vs. 158 ± 39 ml; p < 0.021) and shorter surgery time (135 ± 39 vs. 182 ± 68 min; p = 0.043), with no differences in median LOS (3 days in both groups). No intraoperative complications or conversion was reported. Five postoperative complications were observed: 4 in LAS patients (17.4%) versus only one in RAS (1.6%; p = 0.021). One reintervention was required in LAS group due to hemoperitoneum 12 h after splenectomy. RAS patients had lower postoperative blood transfusion requirements (1.6% vs. 13.0%; p = 0.025) and lower readmission rate (3.3 vs. 17.4%; p = 0.042). No differences were observed when comparing the median economic costs ($25,645 LAS vs. $28,135 RAS; p = 0.215). Robotic assisted splenectomy may be considered as a safe and feasible option in children compared to the traditional laparoscopic approach. Level of evidence: III.

A case of multifocal sclerosis angiomatoid nodular transformations of the spleen occurring after partial splenic infarction with transcatheter arterial embolization for splenic artery aneurysm.

A 48-year-old woman underwent transcatheter arterial embolization (TAE) for a splenic artery aneurysm, which resulted in a partial splenic infarction in the middle lobe. Five years after TAE, a 20-mm diameter mass in the noninfarcted area of the spleen was detected on imaging, which grew to 25 mm in diameter after 6 months. MRI after gadolinium administration showed a 35 × 34 mm mass within the superior pole and 15 × 12 mm mass within the inferior pole. The patient underwent laparoscopic splenectomy and had an uneventful postoperative recovery. No evidence of recurrence was observed during the 2-year follow-up period after surgery. The mass was pathologically confirmed to be sclerosing angiomatoid nodular transformation (SANT) of the spleen. While some studies hypothesize that SANT is a response to vascular injury or trauma, to the best of our knowledge, there have been no previous reports of SANT occurring after procedures directly affecting splenic blood flow. Additionally, multifocal SANTs are reported to be very rare, accounting for only 4.7% of all reported SANTs of the spleen. We highlight a rare course of SANT of the spleen and discuss the possible relationship between blood flow abnormalities and the appearance of SANT.

Splenectomy outcomes in immune cytopenias: Treatment outcomes and determinants of response.

BACKGROUND: Splenectomy is commonly used to treat refractory immune-mediated cytopenia, but there are no established factors that are associated with response to the procedure. OBJECTIVES: A cohort study was conducted to evaluate the hematologic and surgical outcomes of splenectomy in adult patients with immune cytopenias and identify preoperative factors associated with response. METHODS: Data from the Cleveland Clinic Foundation for 1824 patients aged over 18 who underwent splenectomy from 2002 to 2020 were analyzed. RESULTS: The study found that the most common indications for splenectomy were immune thrombocytopenic purpura (ITP) and autoimmune hemolytic anemia, with a median age of 55 years and median time from diagnosis to splenectomy of 11 months. Hematologic response rates were 74% overall, with relapse in 12% of cases. Postsplenectomy discordant diagnoses were present in 13% of patients, associated with higher relapse rates. Surgery-related complications occurred in 12% of cases, whereas only 3% of patients died from disease complications. On univariate analysis, preoperative factors associated with splenectomy treatment failure were ≥3 lines of pharmacologic treatment, whereas isolated thrombocytopenia, primary ITP, and age ≤40 years had a strong association with response. The multivariable regression confirmed that treatment failure with multiple lines of medical therapy was associated with the failure to respond to splenectomy. CONCLUSION: Overall, the study demonstrates that splenectomy is an effective treatment option for immune-mediated cytopenias with a low complication rate.

Clamp-crushing Pancreatic Transection in Minimally Invasive Distal Pancreatectomy.

BACKGROUND: Minimally invasive distal pancreatectomy has become a widely accepted procedure for tumors located in the pancreatic body or tail. However, pancreatic transection by linear stapler is generally avoided for pancreatic body tumors located above the portal vein because the surgical margin width is narrowed after taking into account the cutting allowance for insertion of the stapling device. Herein, we report a parenchymal clamp-crushing procedure that provides a sufficient surgical margin in pancreatic transection. METHODS: Two patients with suspected early pancreatic cancer underwent pancreatic transection using the clamp-crushing procedure. The planned pancreatic transection line was set just to the left of the gastroduodenal artery in both cases. Robotic and laparoscopic distal pancreatectomy were performed in 1 patient each. Patients were positioned supine with split legs. Parenchymal transection was performed with crushing by VIO 3 (ERBE Elektromedizin) operated in softCOAG Bipolar mode with Effect 2/modulation 50. After crushing, remnant tissue was cut in autoCUT Bipolar mode operated by VIO 3 with Effect 2/modulation 50, or cut after secured by clipping. RESULTS: The surgical duration was 253 and 212 minutes, and estimated blood loss was 0 and 50 mL in the 2 patients, and both were discharged with uneventful courses. Pathologic examination confirmed a negative surgical margin in both patients. CONCLUSION: Clamp-crushing pancreatic transection for distal pancreatectomy might be a suitable treatment option for achieving sufficient surgical margin in pancreatic body tumors located close to the portal vein.

Laparoscopic partial splenectomy in a patient with splenic hemangioma after distal gastrectomy for a neuroendocrine tumor.

Herein, we report the case of a patient with splenic hemangioma after distal gastrectomy who was treated with laparoscopic partial splenectomy. A 64-year-old woman previously underwent laparoscopic distal gastrectomy with regional lymph-node dissection for a gastric neuroendocrine tumor (G3) with venous infiltration and no lymph-node metastases. Periodic follow-up abdominal computed tomography revealed a well-defined, heterogeneous mass in the lower pole of the spleen 5 years after the operation, which grew from 12 to 19 mm 1 year later. A laparoscopic partial splenectomy was planned. During surgery, a smooth-surfaced mass with a lighter color than that of the surrounding area was observed at the lower pole of the spleen. The inferior polar branch of the splenic artery was transected, and the ischemic area of the lower pole of the spleen, where the tumor was present, was confirmed. First, the line used to perform splenic transection was determined using soft coagulation. The splenic parenchyma was then gradually transected using a vessel-sealing device system, and partial splenectomy was possible with almost no bleeding. The patient was discharged on postoperative day 8 without any complications. Pathological examination revealed a hemangioma without any malignant findings. Laparoscopic partial splenectomy is a safe and useful procedure that can be performed, considering the tumor size and location.

Unusual Case of Splenic Metastasis in Adenosquamous Carcinoma of the Cervix Uteri: Diagnosis and Treatment Considerations.

BACKGROUND Due to several factors such as its specific cellular and biochemical microenvironment, the spleen is not a predestined organ of frequent metastatic colonization in the case of primary solid carcinoma. Hence, the mode of diagnosis and the preferred treatment of a lesion highly suspicious of splenic metastasis must be decided on a case-by-case basis, considering not only the biological tumor entity but also the stage of the primary disease. CASE REPORT In the present case, we demonstrate the clinical course of a 37-year-old female patient who initially presented to our clinic with irregular vaginal bleeding. A consecutive gynecological examination revealed a 3×3-cm large mass of the cervix uteri, and the subsequent histomorphological workup led to the diagnosis of an adenosquamous carcinoma of the cervix uteri. Therapeutically, the patient received multimodal treatment, namely radical hysterectomy with adjuvant radio-chemotherapy. After 1.5 years, the patient presented to our Emergency Department with intermittent left-sided abdominal pain. Subsequent abdominal imaging (computed tomography scan, magnetic resonance imaging, positron emission tomography) determined a metabolically active splenic lesion with a central necrosis - signs of malignancy in line with a splenic metastasis. Presentation and discussion of the case within our interdisciplinary tumor board led to the decision of splenectomy followed by chemotherapy, a procedure that could be considered as therapeutic treatment in such exceptional cases. CONCLUSIONS The collection and reporting of atypical clinical courses remains a key factor in precision medicine to enable the most evidence-based decision making in such cases.

Using saline bags instead of commercial retrieval bags to reduce the cost of splenic retrieval after laparoscopic splenectomy.

BACKGROUND: Laparoscopic splenectomy (LS) is considered the gold standard treatment in adults with idiopathic thrombocytopenic purpura (ITP) refractory to medical therapy. However, the retrieval of the spleen in LS is still a technical challenge, despite the use of various commercial retrieval bags. This study reports the feasibility and reliability of using a saline bag for spleen retrieval in a reduced port splenectomy. METHODS: Between 2007 and 2020, 55 consecutive patients underwent LS for ITP. Data were collected retrospectively. To retrieve the spleen, a 1 liter sterile saline bag was used. RESULTS: Fifty-five patients underwent LS. There was only one complication related to the saline bag: an iatrogenic ileal injury during the morselization process. CONCLUSION: One-liter saline bag is feasible, and widely available. No additional instruments or cost is required and there is no need to extend the wound for spleen retrieval during LS. KEY WORDS: Idiopathic thrombocytopenic purpura, Laparoscopic surgery, Splenectomy, Techniques.

[Surgery for primary splenic tumors and metastases of the spleen]. / Chirurgie bei primären Milztumoren und Metastasen der Milz.

The correct indications for surgical treatment of primary splenic tumors as well as metastases of the spleen are challenging due to the rarity of the various entities. Primary solid splenic tumors include benign lesions, such as hemangiomas, hamartomas and sclerosing angiomatous nodular transformation (SANT) of the spleen. In these cases, surgical treatment is indicated only in the case of inconclusive imaging and after careful consideration of the risk-benefit ratio, even in the case of pronounced symptoms. In contrast, primary angiosarcoma or undifferentiated pleomorphic sarcoma as highly malignant tumors represent an urgent indication for surgery. Although more frequent than primary splenic malignancies, secondary splenic tumors are also not that frequent. Solitary splenic metastases are rare; however, from an oncological point of view they can be treated by resection. In the case of oligometastasis with splenic involvement, splenectomy is used only as part of a palliative concept in cases of pronounced symptoms or in the context of cytoreductive surgery. In general, the laparoscopic approach is to be preferred when the operation is technically feasible as it is associated with fewer pulmonary and infectious complications and a shorter hospital stay. In addition, to reduce the risk of severe infections after splenectomy, the option of partial splenectomy should be considered, especially for benign lesions. A thorough informing of the patient regarding both intraoperative and perioperative risks as well as potential long-term sequelae, especially severe infectious diseases, is an essential component of informed consent before surgery.

[Splenic surgery in hematological diseases : Indications and surgical technique]. / Chirurgie der Milz bei hämatologischen Erkrankungen : Indikationen und operative Technik.

BACKGROUND: Splenic surgery in hematological disorders requires a well-weighted decision on the indications because the medical treatment has rapidly changed in recent years due to new pharmaceutical approaches. OBJECTIVE: Summary of the indications, surgical procedures and perioperative management regarding operative interventions on the spleen in hematological disorders. MATERIAL AND METHODS: Selective literature search and summary of reviews and guideline recommendations. RESULTS: In hematological disorders surgical procedures of the spleen (splenectomy and partial splenectomy) are an important part of the repertoire in the treatment. In recent years the indications for surgery have become narrower because of new forms of medicinal treatment. Especially in hereditary spherocytosis, immune thrombocytopenia and symptomatic splenomegaly and hypersplenism it is still of importance. The minimally invasive splenectomy is regarded as the gold standard. The spleen has an important immune and sequestration function, therefore preoperative and postoperative infectious and thromboembolic events have to be anticipated and prevented. A close interdisciplinary cooperation with hematologists is essential for an optimal outcome of patients. CONCLUSION: The minimally invasive splenectomy and partial splenectomy are part of the surgical repertoire in the diagnostics and treatment of hematological disorders. Because of novel medicinal approaches the therapeutic protocols are continuously changing. A close cooperation with hematologists is important for the optimal evaluation of the indications and the perioperative management.

Porto-spleno-mesenteric venous thrombosis after elective splenectomy: a retrospective cohort study.

Background: Elective splenectomy is the main treatment for a wide range of haematological diseases. Porto-spleno-mesenteric venous thrombosis represents one of the most severe complications of this procedure. The aim of this study was to evaluate risk factors associated with development of porto-spleno-mesenteric venous thrombosis after elective splenectomy. Methods: All cases of elective splenectomy carried out from April 1st 2017 to January 31st 2023 were included in this single centre retrospective cohort study. Patients' demographics and perioperative data were analysed and correlated with the incidence of postoperative thrombosis. All patients underwent postoperative doppler ultrasound screening for thrombosis. Analysis was performed using SPSS 28, with p-value < 0.05 considered significant. Results: Twenty-two patients (10 women, 12 men) underwent splenectomy during the study period. Indications were: immune thrombocytopenia (n: 6), myeloproliferative disorder (n: 6), hereditary spherocytosis (n: 4), thalassemia (n: 1), lymphoma (n: 1), leukaemia (n: 1), other malignancies (n: 3). Six patients developed porto-spleno-mesenteric venous thrombosis and only 2 of them were symptomatic. Patients were treated with anticoagulation therapy with complete resolution. Analysis identified three main factors associated with thrombosis: spleen diameter (p = 0.03), myeloproliferative disorder (p = 0.02), intraoperative platelet transfusion (p = 0.002) and intraoperative red blood cells transfusion (p = 0.009). Conclusion: Standardized postoperative screening allows prompt diagnosis and treatment of porto-spleno-mesenteric venous thrombosis even in asymptomatic cases. Patient with splenomegaly and affected by myeloproliferative disorder have a greater risk to develop this complication.

The Early Initiation of Perioperative Anticoagulation Therapy in Cirrhotic Patients with Portal Hypertension After Laparoscopic Splenectomy Plus Esophagogastric Devascularization: A 10-Year Single-Center Experience.

Background: Portal veinous system thrombosis (PVST) is a common complication after laparoscopic splenectomy plus esophagogastric devascularization (LSED). Anticoagulation therapy was still in debate in LSED perioperation. This study aimed to determine the postoperative risk factors of PVST, the efficacy and safety of the anticoagulation therapy after LSED procedure, and the potential impact of anticoagulation on patients' liver function and overall survival (OS). Methods: Three hundred patients who underwent LSED were retrospectively enrolled and analyzed in the study. The characteristics of patients, perioperative parameters, risk of PVST, and long-term follow-up data were recorded and analyzed. Results: One hundred eighty six of 300 patients received perioperative anticoagulation therapy (p-AT) postoperation, while 114 patients did not receive p-AT (non-p-AT). The non-p-AT group had more intraoperative blood loss, PVST, longer abdominal drain days, and postoperative hospital stays separately compared with the p-AT group. No significant difference of postoperative complications was found between the two groups. In the 1-year follow-up postoperation, both groups had great improvement in hypersplenism and the portal vein hemodynamics. During the 10-year follow-up period, the incidence of PVST was significantly higher in the non-p-AT group than in the p-AT group. Anticoagulation therapy, sex, variceal hemorrhage history, portal vein diameter, and portal vein velocity were the independent prognostic factors determined by the Cox regression analysis for PVST. The thrombosis-free survival rate (P = .002), recurrent hemorrhage-free survival rate (P < .01), and the OS rate (P < .01) were significantly lower in the non-p-AT group than in the p-AT group. Conclusions: The initiate use of anticoagulation therapy in postoperation of LSED is effective and safe in cirrhotic patients. The anticoagulation therapy after LSED will help decrease portal vein thrombosis, the rebleeding rate, and extend the OS of the patients, especially among women, with variceal hemorrhage history, high portal vein diameter, and low portal vein velocity.

Comparative analysis of laparoscopic and open surgical techniques for nonparasitic splenic cyst management in children: a proposed prediction index.

OBJECTIVE: In this research, our goal is to carry out a retrospective assessment of patients who received surgical treatment for nonparasitic splenic cysts (NPSCs) and to propose an innovative index (Karakuz Index) for predicting the optimal surgical approach. PATIENTS AND METHODS: This study is a retrospective analysis of 48 pediatric patients who underwent surgical treatment for nonparasitic splenic cysts. The patient population was divided into two groups based on the surgical approach: open surgery (n=37) and laparoscopic surgery (n=11). RESULTS: Of the 256 patients with nonparasitic splenic cysts (NPSCs), 48 patients underwent surgical treatment (18.8%). The average age was 11.4±4.2 years, and the majority were female (52%). Surgical approaches included laparoscopic (23%) and open surgery (77%), with cystectomy, partial splenectomy, and total splenectomy performed (48%, 23%, and 29%, respectively). The Karakuz Index, a novel metric, also showed significant differences between the two groups. Histopathological findings and recurrence rates were similar between both approaches (p=0.335 and p=0.229, respectively). The Karakuz Index demonstrated a sensitivity of 60% and a specificity of 91% at a cut-off value of 16. CONCLUSIONS: The novel Karakuz Index demonstrated promising discriminatory capacity and requires further research in larger studies.

Selection of surgical modality for massive splenomegaly in children.

BACKGROUND: Laparoscopic splenectomy (LS), a treatment for both benign and malignant splenic diseases, can prove technically challenging in patients with massive splenomegaly. In particular, the optimal surgical modality for treating massive splenomegaly in children remains controversial. METHODS: The clinicopathologic data of 289 pediatric patients undergoing splenectomy for massive splenomegaly were studied in a retrospective analysis. Accordingly, the patients were classified into the LS surgery group and open splenectomy (OS) surgery group. In the laparoscopy cohort, they were separated into two subgroups according to the method of surgery: the multi-incision laparoscopic splenectomy (MILS) and the single-incision laparoscopic splenectomy (SILS) surgery groups, respectively. Patient demographics, clinical data, surgery, complications, and postoperative recovery underwent analysis. Concurrently, we compared the risk of adverse laparoscopic splenectomy outcomes utilizing univariable and multivariable logistic regression. RESULTS: The total operation time proved remarkably shorter in the OS group in contrast to the LS group (149.87 ± 61.44 versus 188.20 ± 52.51 min, P < 0.001). Relative to the OS group, the LS group exhibited lowered postoperative pain scores, bowel recovery time, and postoperative hospitalization time (P < 0.001). No remarkable difference existed in post-operation complications or mortality (P > 0.05). Nevertheless, the operation duration was remarkably longer in the SILS surgery group than in the MILS surgery group (200 ± 46.11 versus 171.39 ± 40.30 min, P = 0.02). Meanwhile, the operative duration of MILS and SILS displayed a remarkable positive association with splenic length. Moreover, the operative duration of SILS displayed a remarkable positive association with the age, weight, and height of the sick children. Splenic length proved an independent risk factor of adverse outcomes (P < 0.001, OR 1.378). CONCLUSIONS: For pediatric patients with massive splenomegaly who can tolerate prolonged anesthesia and operative procedures, LS surgery proves the optimal treatment regimen. SILS remains a novel surgery therapy which may be deemed a substitutional surgery approach for treating massive splenomegaly.

LAPAROSCOPIC APPROACH TO A GIANT RUPTURED SPLENIC CYST: A CHALLENGING CASE REPORT.

Splenic cysts are rare; their absence of an epithelial wall determines whether they're real cysts or pseudocysts. Spontaneous nonparasitic actual tumors are those that develop early in life at the anterior pole of the splenic and are typically epidermoid, dermoid, or endodermal. Surgical therapy is suggested for symptomatic, large (more than 5 cm) cysts or complicated. Inhaling splenic excision is a substitute for surgery, depending on the quantity, location, connection to the hilus, and dimension of the tumors. With an emphasis on less invasive treatments that preserve the spleen, laparoscopic methods have already established themselves as the accepted method for treating numerous disorders, including splenic cysts. They describe the effective decapsulation of a massive epidermoid spleen tumor under a prolonged, partially endoscopic technique. Laparoscopy, an operation commonly referred to as surgery with minimally invasive or keyhole surgery, is a technique that makes many tiny incisions in the belly to carry out different surgical procedures.

Long-term haematological response and maintained immunological function after laparoscopic subtotal splenectomy in patients with hereditary spherocytosis.

INTRODUCTION: Subtotal or total splenectomy are recommended in severe and should be considered in intermediate forms of hereditary spherocytosis (HS). Data on laparoscopic subtotal splenectomy (LSTS) in HS patients are sparse. METHODS: Thirty three patients with HS (median age 10.7 years (yrs), range 1.8-15.5) underwent LSTS. Baseline and follow-up investigation included haematological parameters, microscopic analysis of pitted erythrocytes (pitE), and B-cell subpopulations assessed by flow cytometry. Results were compared to those of non-splenectomised HS patients, HS patients after total splenectomy (TS), and healthy individuals. RESULTS: After LSTS, haemoglobin levels were normalised in all patients. During median long-term follow-up of 3.9 yrs (range 1.1-14.9), only four patients presented mild anaemia. Despite re-growing of the remnant spleen none of the patients required a second surgical intervention. As compared to TS, PitE in LSTS patients were significantly lower and indicated normal to only moderately decreased spleen function. Relative but not absolute IgM memory B-cell counts were reduced in both LSTS and TS patients. CONCLUSIONS: LSTS is effective for the treatment of patients with HS. A small remnant spleen is sufficient to provide adequate phagocytic function and to induce a pool of IgM memory B-cells.

Refractory immune thrombocytopenic purpura (ITP) after accessory splenectomy: A case report and literature review.

Immune thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by a platelet count of less than 100 x 109 /L, resulting from antibody-mediated platelet destruction. Treatment for ITP typically involves steroids, and intravenous immunoglobulins (IVIG) can be added. Splenectomy is performed in cases with refractory ITP. Rituximab can suppress immunity but has limited efficacy in ITP cases. Herein, we present a rare case of a 30-year-old female who was first diagnosed with ITP and underwent a splenectomy two years later. However, seven years after surgery, she was presented with symptoms of ITP. A splenic scan showed an accessory spleen in the spleen bed, for which she underwent accessory spleen removal surgery. Her laboratory tests three days post-operation showed a rise in platelet count and hence was discharged a few days later. The patient had recurrent attacks of ITP even after the removal of the normal and accessory spleen, suggesting that accessory spleen removal may not always be an effective treatment for ITP. The patient eventually died. While splenectomy is a common treatment for ITP, it may not always be effective in all cases, and other treatments such as bone marrow transplantation may be necessary.

Risk Factors for a High Comprehensive Complication Index after Splenectomy Plus Pericardial Devascularization for Portal Hypertension.

BACKGROUND/AIMS: Mathematical integration of all complications from the Clavien-Dindo classification into one number called the comprehensive complication index provides a novel method to capture morbidity. This objective of this study was to compare the evaluations of complications between the novel comprehensive complication index and Clavien-Dindo classification for portal hypertension patients who underwent splenectomy plus pericardial devascularization. MATERIALS AND METHODS: Patients treated with either splenectomy plus simplified pericardial devascularization or splenectomy plus traditional pericardial devascularization were included retrospectively. Correlation and logistic regression analyses of the postoperative hospital stay and total hospitalization expense were compared between the comprehensive complication index and Clavien-Dindo classification. The cumulative sum-comprehensive complication index was generated and compared between operation types. RESULTS: The Child-Pugh classification at admission, spleen thickness, and intraoperative blood loss were risk factors for high comprehensive complication index. Comprehensive complication index showed a stronger relationship with the postoperative hospital stay and total hospitalization expense than the Clavien-Dindo classification. Logistic regression analysis of the postoperative hospital stay demonstrated that the R2 values for the comprehensive complication index and Clavien-Dindo classification were 0.15 and 0.14, respectively. The cumulative sum-comprehensive complication index graph showed a steady dynamic decrease in the cumulative sum score for the individual operation type, with splenectomy plus simplified pericardial devascularization revealing a more notable decrease than splenectomy plus traditional pericardial devascularization. CONCLUSIONS: Comprehensive complication index is an excellent method to assess postoperative morbidity in portal hypertension patients. The cumulative sum-comprehensive complication index chart can better dynamically monitor and compare different operation types. Splenectomy plus simplified pericardial devascularization is better than splenectomy plus traditional pericardial devascularization at decreasing cumulative sum-comprehensive complication index.

Revitalize splenic functions. Following a splenectomy for trauma, a small amount of splenic autotransplantation was performed.

INTRODUCTION: The spleen is a responsible significant part of the immune system; after Splenectomy following trauma, the immune system changes; splenic autotransplantation can preserve the immune system after trauma and Splenectomy. BACKGROUND: Patients can be protected from immune dysfunction by autotransplanting splenic tissues after splenectomy following trauma because their immune systems and spleens are changed. Patients can gain their immune function after splenic autotransplantation. METHODS: Patient classification methods are into three categories, Group A, 6 cases with auto-translation; Group B, 6 cases without transplantation; Group C, seven regular people serving as the control. AIM OF WORK: The aim of the work is not to compare outcome methods or compare types of autotransplantation; This work aims to document postoperative radiological, immunological, clinical, and hematological investigations. We concentrated on the results of investigations more than the types of operation or approach or types of autotransplantation. RESULTS: We showed that, after comparing each group with normal individuals subjects, patients who did not undergo autotransplantation had significantly higher platelet counts, a more significant percentage of micronucleated reticulocytes, increased levels of naive B lymphocytes, changes in class-switched memory and class-unswitched memory B cells, and higher levels of PD1 on CD8 + T lymphocytes. Nevertheless, neither splenic autotransplant patients nor the average general population showed any appreciable variations in any of the parameters. CONCLUSIONS: Spleen's activities with adequate hemocatheter activity and recovery of the immunological deficit after splenic autotransplantation.
