RESUMO

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.

RESUMO

BACKGROUND: Dogs with retroperitoneal hemangiosarcoma (HSA) exhibit variable postoperative median survival times (MST). OBJECTIVE: To retrospectively evaluate the prognostic value of selected tumour-related factors, such as tumour size, rupture, invasion into adjacent tissue, involvement of lymph node and distant metastasis, they were analysed in dogs with retroperitoneal HSA. METHODS: Ten dogs with retroperitoneal HSA managed solely with surgical excision were reviewed and compared with spleen (71) and liver (9) HSA. The Kaplan-Meier method and log-rank analysis were used compare MSTs between factors. Multivariable Cox proportional-hazard analysis was used to compare differences between arising sites. RESULTS: Retroperitoneal HSA showed comparatively longer postoperative MST compared with that of spleen and liver HSA and demonstrated significantly longer MST (p = 0.003) for tumours ≥5 cm (195 days) than <5 cm (70 days). Spleen HSA revealed significantly shorter MSTs in involvement of distant lymph nodes (23 days) and distant metastasis (39 days) than those in negative (83 days, p = 0.002 and 110 days, p < 0.001, respectively). Liver HSA also revealed significantly shorter MST (16.5 days compared with 98 days, p = 0.003) for distant metastasis. Additionally, hazard ratios (HRs) and their forest plot for overall HSA revealed as poor prognostic factors, arising sites (spleen; HR 2.78, p = 0.016 and liver; HR 3.62, p = 0.019), involvement of distant lymph nodes (HR 2.43, p = 0.014), and distant metastasis (HR 2.86, p < 0.001), and as better prognostic factor of tumour size ≥5 cm (HR 0.53, p = 0.037). CONCLUSION: In combination with overall HSA, retroperitoneal HSA shows comparatively longer postoperative MST compared to spleen and liver HSA, associated with tumour size ≥5 cm suggesting better prognostic factor.

RESUMO

RATIONALE: Sclerosing angiomatoid nodular transformation (SANT) of the spleen is an uncommon benign vascular lesion with an obscure etiology. It predominantly affects middle-aged women and presents with nonspecific clinical signs, making preoperative diagnosis challenging. The definitive diagnosis of SANT relies on pathological examination following splenectomy. This study aims to contribute to the understanding of SANT by presenting a case series and reviewing the literature to highlight the clinical presentation, diagnostic challenges, and treatment outcomes. PATIENT CONCERNS: In this retrospective study, we analyzed the clinical data of 3 patients with confirmed SANT admitted from November 2013 to October 2023. The cases include a 25-year-old male, a 15-year-old female, and a 39-year-old male, each with a splenic mass. DIAGNOSES AND INTERVENTIONS: All of the three cases were treated by laparoscopic splenectomy (LS). Pathological examination confirmed SANT in all cases. OUTCOMES: No recurrence or metastasis was observed during a 10-year follow-up for the first 2 cases, and the third case showed no abnormalities at 2 months postoperatively. Despite its rarity, SANT is a significant condition due to its potential for misdiagnosis and the importance of distinguishing it from malignant lesions. The study underscores the utility of LS as a safe and effective treatment option. LESSONS: SANT is a rare benign tumor of the spleen, and the preoperative diagnosis of whom is challenging. LS is a safe and effective treatment for SANT, with satisfactory surgical outcomes and favorable long-term prognosis on follow-up. The study contributes to the limited body of research on this rare condition and calls for larger studies to validate these findings and improve clinical management.

RESUMO

While the importance of conversion surgery has increased with the development of systemic chemotherapy for gastric cancer (GC), reports of conversion surgery for patients with GC with distant metastasis and tumor thrombus are extremely scarce, and a definitive surgical strategy has yet to be established. Herein, we report a 67-year-old man with left abdominal pain referred to our hospital following a diagnosis of unresectable GC. Esophagogastroduodenoscopy and contrast-enhanced abdominal computed tomography (CT) revealed advanced GC with splenic metastasis. A splenic vein tumor thrombus (SVTT) and a continuous thrombus to the main trunk of the portal vein were detected. The patient was treated with anticoagulation therapy and systemic chemotherapy comprising S-1 and oxaliplatin. One year following chemotherapy initiation, a CT scan revealed progressive disease (PD); therefore, the chemotherapy regimen was switched to ramucirumab with paclitaxel. After 10 courses of chemotherapy resulting in primary tumor and SVTT shrinkage, the patient underwent laparoscopic total gastrectomy (LTG) and distal pancreaticosplenectomy (DPS). He was discharged without complications and remained alive 6 months postoperatively without recurrence. In summary, the wait-and-see approach was effective in a patient with GC with splenic metastasis and SVTT, ultimately leading to an R0 resection performed via LTG and DPS.

RESUMO

BACKGROUND: Current study aimed to investigate the clinical characterization, differential diagnosis, and treatment of splenic littoral cell angioma (LCA). METHODS: A retrospective analysis was performed for 10 LCA cases admitted to Huzhou Central Hospital from 2007 to 2023, for clinical manifestations, hematological tests, imaging features, pathological features, treatment methods, and prognosis along with the relevant literature was also reviewed. RESULTS: During examinations, no specific clinical manifestations and hematological abnormalities were seen in all 10 cases of LCA. Imaging observations depicted single or even multiple spherical lesions in the spleen. Plains shown by computed tomography (CT) were found somewhat equal or slightly lower in density. On the other hand, magnetic resonance imaging (MRI) plain scans viz. T1 weighted image showed equal low and mixed signals while T2-weighted showed high and low mixed signals. Moreover, punctate low signals could be seen in high signals named "freckle sign" in MRI scans. On contrast-enhanced CT scans, the enhancement of the lesions was not obvious in the arterial phase, and some of the lesions showed edged ring-like enhancements and "filling lake" progressive enhancement during the venous phase and delayed phase. In multiple lesions, the number of enhanced scan lesions showed a variable changing pattern "less-more-less." MRI-enhanced scan showed the characteristics of "fast in and slow out." Microscopic examinations identified tumor tissue actually composed of sinus-like lacunae that anastomosed with each other in the form of a network. Furthermore, cystic expansion and pseudopapillary protrusions were also seen in the dilated sinus cavity which was lined with single-layer endothelial cells having conspicuous cytoplasmic hemosiderin. High immunophenotypic expressions of vascular endothelial cell phenotype (CD31, CD34, FVIII) and tissue cell phenotype (CD68) were also seen. Total and partial splenectomy were performed in 8 and 2 patients, respectively, and follow-up examinations showed survival in all patients with no recurrence. CONCLUSION: LCA is a rare splenic benign lesion with atypical clinical manifestations. CT and MRI imaging are important tools in preoperative diagnosis based on pathomorphological and immunohistochemical examinations. Splenectomy is a superior therapeutic choice with significant impacts and prognosis.

RESUMO

Background: Splenic sclerosing angiomatoid nodular transformation (SANT) is a rare benign nodular lesion in the red medulla of the spleen. In the past, SANT has not been consistently recognized as the name for this condition and was often misdiagnosed for other conditions. In recent years, SANT has been acknowledged by most scholars as multiple reports have been published. Aim: To assess the clinicopathological features of SANT to identify the histological characteristics of SANT to improve diagnosis and clinical treatment. Materials and Methods: We assessed 25 cases of SANT diagnosed at Zhongshan Hospital affiliated with Fudan University from September 2014 to October 2021, including 14 men and 11 women, aged 24-62 years old. Results: Fourteen cases were complicated with benign tumors of the liver, pancreas, kidney, uterus, and prostate. One case was complicated with renal clear cell carcinoma, and one was complicated with hepatocellular carcinoma. The gross neoplasm is multinodular and well defined. Histologically, angiomatoid nodules are composed of fattened, round, or irregular blood vessels, with or without red blood cells in the lumen, with unequal red blood cell extravasation, and fibrocytes around the nodules. The hemangiomatous nodules were positive for CD31 and CD34, while the vascular wall smooth muscle cells and fibrocytes around the nodules were positive for SMA. Conclusion: The diagnosis of SANT requires a combination of immunohistochemical and histological features, and early splenectomy is crucial for treatment.

RESUMO

Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention.

RESUMO

Spontaneous rupture of a primary hepatocellular carcinoma (HCC) is a frequently observed and fatal complication. However, the rupture of lymph node (LN) metastases from HCC is rare. A 79 year-old male with hepatitis B underwent three liver resections for HCC. Two years and 6 months after the last liver resection, enhanced computed tomography (CT) revealed a nodule with a diameter of 3 cm in the lower pole of the spleen. Splenic metastasis of HCC was suspected, and splenectomy was scheduled. During our hospital stay for a urinary tract infection before the scheduled operation, he complained of acute left-sided abdominal pain, and CT showed intra-abdominal hemorrhage due to rupture of the splenic tumor. Emergency splenectomy was performed, and the postoperative course was uneventful. Histopathological examination revealed a poorly differentiated HCC in the lower splenic pole lesion, which contained LN structures. The ruptured lesion was diagnosed as splenic hilar LN metastasis of HCC. Although laparoscopic partial liver resection was performed for intrahepatic recurrence, and atezolizumab plus bevacizumab therapy was administered for peritoneal metastases, the patient was alive 25 months after the splenectomy. Our case suggests that emergency surgery for LN metastatic rupture can achieve hemostasis and lead to improved survival outcomes.

RESUMO

INTRODUCTION: While intracorporeal anastomosis (IA) has been widely used in totally laparoscopic right colectomy, its application in laparoscopic segmental left colectomy for splenic flexure cancer remains underexplored, particularly in large-scale studies with long-term outcomes. This research aims to assess the technical feasibility and oncological efficacy of IA in treating colonic splenic flexure carcinoma, drawing insights from both short-term and long-term outcomes of a retrospective cohort. MATERIALS AND METHODS: A retrospective analysis was conducted on 342 patients diagnosed with colonic splenic flexure carcinoma in three Chinese medical centers. These patients underwent laparoscopic segmental left colectomy between December 2014 and December 2019 across three medical institutions. Comprehensive data encompassing demographics, disease features, pathological characteristics, operative details, and both short-term and long-term outcomes were gathered and scrutinized. Using propensity scores, each patient from the IA cohort was paired with a counterpart from the extracorporeal anastomosis (EA) cohort. RESULTS: IA was performed on 129 patients, while 213 underwent EA. Post-propensity score matching resulted in 129 matched pairs. After matching, many baseline characteristics were balanced. The IA cohort exhibited several advantages, including shorter incision lengths ( P <0.001) and more extensive proximal and distal resection margins ( P =0.003, P <0.001). Additionally, the IA method facilitated a more rapid postoperative recovery as indicated by quicker return of bowel movements (resumption of passing flatus [2.7 (1.0-7.0) days vs. 3.3 (2.0-8.0) days, P <0.001] and defecation [3.7 (1.0-9.0)] days vs. 4.5 (2.0-9.0) days, P <0.001]), faster discharges [6.6 (3.0-15.0) days vs. 8.3 (5.0-20.0) days, P <0.001], and decreased need for rescue analgesics ( P <0.001). The rate of postoperative complications, as rated by the Clavien-Dindo classification, remained consistent across both techniques ( P =0.087). Furthermore, the cosmetic outcome rated by Patient Scar Assessment Questionnaire and Scoring System (PSAQ) was markedly superior in the IA group ( P <0.001). Both approaches demonstrated equivalent 5-year overall (82.7% vs. 82.1%, P =0.419) and disease-free survival (80.9% vs. 78.1%, P =0.476). Subsequent stratification analysis revealed that IA achieved comparable 5-year overall (80.7% vs. 82.0%, P =0.647) and disease-free survival (78.1% vs. 76.4%, P =0.734) in patients with locally advanced colon cancer. CONCLUSION: Employing IA for laparoscopic segmental left colectomy in cases of splenic flexure carcinoma is not only safe but also offers enhanced cosmetic results and expedited postoperative recovery. Oncologically speaking, IA in left segmental colectomy for splenic flexure carcinoma can yield therapeutic outcomes comparable to those of EA, even in patients with locally advanced colon cancer.

RESUMO

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.

RESUMO

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.

RESUMO

PURPOSE: Robotic surgery is becoming increasingly widely used in the field of pediatric surgery. The present study aimed to evaluate the safety and feasibility of robot-assisted resection of benign pediatric splenic tumors and to discuss the technical points. METHODS: A total of 32 patients who were diagnosed with benign splenic tumors and underwent minimally invasive surgery from January 2017 to September 2023 were included in the study. The clinical data including demographic criteria, operative details, and postoperative outcomes were analyzed retrospectively. RESULTS: Thirteen patients underwent robot-assisted surgery, and 19 patients underwent laparoscopic surgery. The median operation time was 150 min, with an interquartile range (IQR) of 120 to 200 min for the robot-assisted group and 140 min with an IQR of 105 to 180 min in the laparoscopic group (P = 0.318). Despite four cases in the laparoscopic group (21%) being converted to laparotomy because of intraoperative bleeding, compared with none in the robot-assisted group, there was no significant difference between two groups (P = 0.128). The intraoperative volume of blood loss was significantly less (P = 0.041), and the hospitalization expense was significantly higher (P = 0.000) in the robot-assisted group than for the laparoscopic group. There was no significant difference in patients' age, tumor size, postoperative feeding time, and the postoperative hospitalization time between two groups (P > 0.05). CONCLUSION: Robot-assisted benign splenic tumor resection was safe and feasible, and it reduced surgical trauma for the pediatric patient.

RESUMO

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.

RESUMO

OBJECTIVE: To determine the prevalence of splenic malignancy in cats undergoing splenectomy and to investigate possible factors associated with post-operative outcome. ANIMALS: 62 client-owned cats that underwent splenectomy. METHODS: Medical records of 4 UK-based referral hospitals were searched and data reviewed retrospectively over 17 years. Factors associated with outcomes post-splenectomy were analyzed. RESULTS: 50 out of 62 cats (81%) were diagnosed with splenic neoplasia. Mast cell tumor ([MCT], 42%), hemangiosarcoma ([HSA], 40%), lymphoma and histiocytic sarcoma (6% each) were the most common tumor types. Fifteen cats (24%) presented with spontaneous hemoabdomen and were all diagnosed with splenic neoplasia. The diagnostic accuracy of cytology to detect splenic malignant lesions was 73% (100% for MCTs and 54% for mesenchymal tumors). Median survival time for cats with nonneoplastic splenic lesions was 715 days (IQR, 18 to 1,368) and 136 days for cats with splenic neoplasia (IQR, 35 to 348); median survival time was longer for cats with splenic MCT when compared to cats with HSA (348 vs 94 days; P < .001). Presence of metastatic disease and anemia (PCV < 24%) at diagnosis were associated with a poorer survival when considering all cats. Presence of anemia, a splenic mass on imaging or spontaneous hemoabdomen were associated with a diagnosis of HSA (P < .001). CLINICAL RELEVANCE: Benign splenic lesions were uncommon in this cohort of cats. Spontaneous hemoabdomen should prompt the clinician to suspect neoplasia in cats with splenic disease. Anemia and evidence of metastasis at diagnosis were poor prognostic factors regardless of the final diagnosis.

RESUMO

BACKGROUND: The purpose of current study was to examine the incidence, characteristics, treatment, and survival of splenic marginal zone lymphoma (SMZL). METHODS: Using SEER-18 database, patients diagnosed with SMZL between 2000 and 2018 were included. Effect of splenectomy on survival was evaluated after balancing the confounding factors by propensity score matching. Rates of splenectomy and 1-year relative survival were calculated for each year. A logistic regression model identified factors related to splenectomy, and a Cox regression model assessed factors linked to overall survival (OS). RESULTS: A total of 2790 patients with SMZL were analyzed. The majority were older than 60 years, female, and white. The age-adjusted incidence of SMZL was 0.17/100,000 person-years, with higher incidence in males. Incidence increased by 0.68%/year and peaked at 80-84 years for both genders. The SMZL-specific survival rates at 3 and 5 years were 89.6% and 85.3%, respectively. Meanwhile, the relative survival rates for the same periods were 88.6% and 85.9%, respectively. Splenectomy patients were more likely to be younger, male, and diagnosed with early-stage disease. Despite the decreasing utilization rate of splenectomy from 59.4% in 2000 to 16.2% in 2018, the 1-year relative survival rate remained relatively stable with minor fluctuations over time. Whether or not the patient underwent splenectomy was not found to be a significant prognostic indicator for OS. CONCLUSIONS: Our study demonstrated a decreasing use of splenectomy but a relatively stable survival in patients with SMZL, highlighting the urgency to better understand the role of splenectomy and its associated outcomes.

RESUMO

Littoral cell angioma is a benign vascular tumour of the spleen, and malign transformation is seldom. The angioma is associated with a high risk of simultaneous occurrence of other primary cancers, and it is of utmost importance to perform extensive diagnostic investigations to detect other cancers. Definitive treatment of littoral cell angioma is surgical resection of the spleen. This is a unique case report about a 73-year-old woman who had a simultaneous adenocarcinoma of the colon and a gastrointestinal stromal tumour. She underwent simultaneous splenectomy with colonic and gastric resection.

RESUMO

BACKGROUND: Splenic flexure tumours (SFC) are uncommon and present at more advanced disease stages. The optimal surgical technique for SFC remains controversial. We sought to compare the short-term outcomes of a left hemicolectomy (LHC) versus an extended resection (subtotal colectomy, STC) for SFCs. METHODS: A retrospective analysis using the Binational Colorectal Cancer Audit (BCCA) registry was performed. All patients with SFC who underwent elective or emergency surgery for a SFC between 2010 and 2021 were included. Primary outcomes included short-term inpatient complications. Secondary outcomes included survival outcomes. RESULTS: Six hundred and ninety-nine patients underwent resections for SFCs. A LHC was more common, performed in 64.1%. Patients having a LHC were significantly older, with proportionally more LHCs done laparoscopically. Overall grade III/IV complications were similar between both operations. Prolonged ileus and return to theatre were significantly higher in patients undergoing a STC. On multivariate analysis, anastomotic leak and overall grade III/IV complications were not independently associated with the type of operation. There was no difference in medial survival based on type of operation. Higher tumour stage (Stage III/IV) were independently associated with worse survival. CONCLUSION: Segmental and extended resections are both oncologically sound procedures for SFCs. Segmental resections are associated with lower rates of prolonged ileus.

RESUMO

Atraumatic splenic rupture (ASR) is a rare occurrence but an important clinical entity. Although trauma is the most common cause of splenic rupture, there is limited literature on ASR. This case report discusses a 59-year-old woman presenting with tension hydrothorax and ASR in the setting of non-small cell lung carcinoma requiring emergent chest tube insertion and emergent splenectomy. Her hospital course was complicated by pulmonary embolism and thrombosis of the inferior vena cava. The patient expired three months after her initial presentation. This patient's presentation represents only the second documented case of atraumatic splenic rupture secondary to metastatic lung carcinoma without pathological evidence of splenic metastasis. Atraumatic splenic rupture secondary to metastatic NSCLC is a rare occurrence; though failure to detect, it may be fatal. Pathologic ASR may be an occult presentation of lung malignancy and in the presence of confirmed NSCLC may portend a poor prognosis.
