Gastrosplenic fistula due to splenic lymphoma: two case reports and review of the literature.

BACKGROUND: Gastrosplenic fistula is a rare and potentially fatal complication of various conditions. Lymphoma is the most common cause. It can occur spontaneously or after chemotherapy. Gastrosplenic fistula diagnosis can be confused with a splenic abscess because of the presence of air into the mass. The computed tomography identification of the fistulous tract is the key to a right diagnosis. Treatment modalities include surgical resection, chemotherapy, or a combination of both. CASE PRESENTATION: Here we report two patients with gastrosplenic fistula due to diffuse large B cell lymphoma. The first patient was a 54-year-old Caucasian woman with an enormous primary splenic diffuse large B cell lymphoma leading to the development of a spontaneous fistula in the stomach. The second patient was a 48-year-old Caucasian male patient with an enormous splenic diffuse large B cell lymphoma complicated by fistula after chemotherapy. Both patients died of septic shock several days after surgery. CONCLUSION: Gastrosplenic fistula is a rare complication with a poor-prognosis, for which surgery is currently the preferred treatment.

Splenic Subcapsular Hematoma from Commercial Air Travel: Case Report of a Unique Incident of Altitude-Associated Splenic Syndrome.

BACKGROUND: Sickle cell trait (SCT), the heterozygous form of sickle cell disease, is generally thought of as a benign condition. However, it is possible for those with SCT to have serious complications, especially when they are exposed to high altitudes where oxygen levels are low. CASE REPORT: We present a case of a 41-year-old man with a history of SCT who developed severe epigastric pain and nearly lost consciousness while traveling on a commercial airplane. His twin brother, who also has SCT, had a similar episode in the past and required a splenectomy. A splenic subcapsular hematoma was found in a computed tomography scan of the abdomen and pelvis with intravenous contrast. He was admitted and managed conservatively until his symptoms resolved. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Though SCT is prevalent in our population, the complications that can arise, such as altitude-associated splenic syndrome, have likely not been thoroughly investigated. Physicians should add this condition to their differential if they practice at locations near airports or in areas of higher altitude and if their patients have a past medical history of SCT.

Splenic abscess due to non-operative management of splenic injury: a case report.

BACKGROUND: Splenic abscess is a rare disease, with incidence of 0.2-0.7% in previous studies. It often appears with left upper quadrant abdominal pain, fever, chills. Splenic abscess often happens because of hematogenous spreading of infections, endocarditis, angioembolization and some other rare reasons. Treatment relies on one of these two methods: percutaneous drainage or surgery. CASE PRESENTATION: A 68-year-old diabetic Asian female (Asian woman) presented with generalized abdominal pain, low blood pressure, tachycardia, fever, lethargy and elevated level of blood sugar. She had history of conservative therapy in intensive care unit due to blunt abdominal trauma and splenic injury. She had a huge splenic abscess in ultrasonography and computed tomography scan so she went under splenectomy. Our patient had a splenic abscess without performing any intervention like angioembolization. CONCLUSION: Immune compromised patients who are selected for nonoperative management after splenic injury need close follow up and evaluating about abscess formation for at least 2 weeks. Early diagnosis and treatment with two methods including percutaneous drainage or splenectomy should be considered and it depends on patient's risk factors, vital signs, general conditions and presence or absence of sepsis.

Are accessory spleen screening and resection in refractory immune cytopenia an effective strategy or a waste of resources?

Splenectomy remains an effective treatment for refractory immune cytopenia (RIC), which encompasses immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA). Accessory spleens (AS) have been described without identifying specific risk factors. We retrospectively analyzed patients with RIC after splenectomy who underwent splenic scintigraphy (SS) at our institution. Seventy-one patients were included. Sixty-two patients had ITP, five had AIHA, and four had Evans syndrome. Seventy-five percent (n = 53) were women. Eleven patients (15.5%) had an AS detected by SS. A complete response (CR) to first-line steroids (odds ratio (OR) 5.75, 95% confidence interval (CI) 1.37-24.14, p = 0.017) and the absence of Howell-Jolly bodies (HJB) in peripheral blood smear (PBS) (OR 11.37, 95% CI 2.70-47.85, p = 0.001) were found to be risk factors. Patients with both elements had a higher rate of AS (83.3%) when compared to those with one or no factors (p < 0.001). Eight patients (73%) underwent an accessory splenectomy: seven (87.5%) achieved a CR, and none had perioperative complications. The presence of HJB in PBS changed from 25 to 87.5% after accessory splenectomy. We recommend the search for an AS via SS in patients with RIC due to ITP, who had a CR to corticosteroids and the absence of HJB in PBS. Accessory splenectomy is a safe and effective procedure.

[Laparoscopic partial resection of spleen in a 15-year-old girl]. / Laparoskopicheskaya partsial'naya rezektsiya selezenki u devochki 15 let.

Non-parasitic splenic cysts account for 0.5-10% of diseases of this organ. Incidence of splenic cysts has increased in recent years that may be associated with widespread use of abdominal imaging. Symptoms are absent in most cases. Splenic cysts > 5 cm are prone to complications such as bleeding, rupture or infection. These patients require surgical treatment. The authors present multilocular splenic cyst in a 15-year-old patient. The girl was followed-up for 2 previous years due to asymptomatic small cyst. However, cyst enlargement required surgical treatment. Examination revealed multilocular cyst 7×10 cm in the upper pole of the spleen. Enzyme immunoassay did not reveal antibodies to echinococcus. Laparoscopic partial resection of spleen was performed. This case is an example of modern surgical approach for nonparasitic splenic cysts characterized by minimally invasive organ-sparing technologies.

[Splenic dysfunction in sickle cell disease: An update]. / Dysfonction splénique au cours de la drépanocytose : mise au point.

The spleen filters blood cells and contributes to the immune defense. The red pulp clears the blood from altered red blood cells via its unique microcirculatory network ; while the white pulp is a secondary lymphoid organ, directly connected to the bloodstream, whose specificity is the defense against encapsulated bacteria through the production of "natural" IgM in the marginal zone. Various health conditions can cause acquired impairment of the splenic function (or hyposplenism) directly and/or through therapeutic splenectomy. Hypo/asplenia is complicated by an increased susceptibility to encapsulated germ infections, but an increased risk of thrombosis and pulmonary hypertension has also been reported after surgical splenectomy. Homozygous sickle cell disease is the most common disease associated with functional asplenia. The latter appears early in childhood likely through repeated ischemic alterations caused by the sickling of red blood cells. In addition, specific complications such as hypersplenism and acute splenic sequestration can occur and may be life-threatening. We provide here an update on the role and physiology of the spleen, which will allow a better understanding of the pathophysiology of spleen damage and its consequences in sickle cell disease.

Efficacy and safety of heparin plus dexamethasone after partial splenic embolization for liver cirrhosis with massive splenomegaly.

PURPOSE: The aim of this study was to investigate the efficacy and safety of the combination of low-molecular-weight heparin + dexamethasone after partial splenic embolization in cirrhotic patients with massive splenomegaly. METHODS: This study included 116 patients with liver cirrhosis complicated with massive splenomegaly who underwent PSE in Union Hospital from January 2016 to December 2019, and they met the criteria. They were divided into two groups: PSE + Hep + Dex group (N = 54) and PSE group (N = 62). We conducted a retrospective study to analyze the efficacy and safety of the two groups of patients. RESULTS: The volume of splenic embolization was 622.34 ± 157.06 cm3 in the PSE + Hep + DEX group and 587.62 ± 175.33 cm3 in the PSE group (P = 0.306). There was no statistically difference in the embolization rate of the spleen between the two groups (P = 0.573). WBC peaked 1 week after PSE and PLT peaked 1 month after PSE in both groups; it gradually decreased later, but was significantly higher than the preoperative level during the 12-month follow-up period. The incidences of abdominal pain (46.3% vs 66.1%, P = 0.039), fever (38.9% vs 75.8%, P < 0.001), PVT (1.9% vs 12.9%, P = 0.026), refractory ascites (5.6% vs 19.4%, P = 0.027) were lower in the PSE + Hep + DEX group than in the PSE group. The VAS score of abdominal pain in PSE group was higher than that in PSE + Hep + DEX group on postoperative days 2-8 (P < 0.05). Splenic abscess occurred in 1(1.6%) patient in the PSE group and none (0.0%) in the PSE + Hep + DEX group (P = 0.349). CONCLUSIONS: The combined use of dexamethasone and low-molecular-weight heparin after PSE is a safe and effective treatment strategy that can significantly reduce the incidence of complications after PSE (such as post-embolization syndrome, PVT, refractory ascites).

Splenic Abscesses in Endocarditis: A Rare Disease with High Mortality. The Experience of a Heart Institute in Brazil.

INTRODUCTION: Splenic abscess secondary to endocarditis is a rare complication with high mortality. The treatment modality, splenectomy versus percutaneous drainage, and the best time, before or after valve replacement, are controversial. In the literature, there are only a few small case series about the subject. The objective of this study is to analyze the experience of a referral center in treating such condition. METHODS: Patients with splenic abscesses due to endocarditis from 2006 to 2020 were retrospectively analyzed. RESULTS: Thirteen patients (mean age 46 years old, 69% male) were identified. Eight patients (62%) had at least 2 comorbidities and 5 (38%) had a history of cardiac surgery. The diagnosis was incidental in 6 (46%). The mean time of abscess diagnosis after endocarditis definition was 14 days. Six patients (46%) had at least two organ dysfunctions. The median APACHE II score was 12 overall, and 24.5 in patients who died. Six patients (46%) had a valve replacement, and in two the abscess was diagnosed postoperatively. Of the other four patients, splenectomy was performed before the cardiac operation in three and at the same time in one. Splenectomy was performed immediately in 9 (69%) patients while three patients had percutaneous drainage (23%), one of which underwent splenectomy due to drainage failure. Exclusive antibiotic treatment was performed on only one patient. The median length of hospitalization was 24 days and mortality was 46%. CONCLUSION: Splenic abscess due to endocarditis is a life-threatening condition with controversial treatment that results in a prolonged length of stay and high mortality.

Laparoscopic organ-sparing surgery for cystic lesions of the spleen - own observations.

<b>Introduction:</b> Splenic cysts are quite rare. In this publication, authors focus on presenting their own observations related to the management of patients with such lesions. </br></br> <b> Aim:</b> To evaluate the effectiveness of laparoscopic procedures in the case of patients with splenic cysts. </br></br> <b>Material and methods:</b> The study included patients treated surgically for cystic lesions located in the spleen at the 2^nd Department of General, Gastroenterological and Oncological Surgery of the Medical University of Bialystok over the years 2017-01.2020. </br></br> <b>Results:</b> All patients were referred for elective excision of the spleen lesion (the size of the lesions ranged from 7 to 15 cm - based on CT examination). In all cases, excision of the anterior wall of the cyst was performed with the help of advanced surgical tools. The duration of the procedure ranged between 65 and 100 minutes. No significant blood loss was observed. No postoperative complications were found. </br></br> <b>Conclusions:</b> In conclusion, sparing laparoscopic surgery for cystic lesions of the spleen seem to be safe and rarely associated with complications or relapses. Extending the scope of the procedure to total splenectomy should also not pose a major problem.

Treatment and outcomes of two pigs treated for hemoabdomen secondary to splenic disease.

OBJECTIVE: To report the management and outcomes of two pigs undergoing emergency surgery for hemoabdomen secondary to splenic disease. STUDY DESIGN: Case report. ANIMAL: Two adult pigs with hemoabdomen and suspected splenic pathology. METHODS: Pigs were admitted for several clinical signs including lethargy, inappetence, vomiting, abdominal distention, hypothermia, and tachycardia. Abdominal ultrasound and abdominocentesis led to a diagnosis of hemoabdomen secondary to splenic disease. RESULTS: The spleen was confirmed as the source of hemorrhage during midline exploratory celiotomy in both pigs. Splenic rupture resulted from splenic vein thrombosis in one pig and splenic torsion in the other. Complications included intraoperative hemorrhage and intraabdominal adhesion formation. Four years following splenectomy, one pig was euthanized because of widespread small intestinal adhesions causing luminal obstruction, while the other pig was euthanized following a diagnosis of chronic myeloid leukemia. CONCLUSIONS: A ventral midline celiotomy provided adequate exposure for splenectomy. The procedure allowed resolution of signs in both pigs. Splenic pathology, such as vessel thrombosis or torsion, may result in splenic rupture and should be considered as a differential in pigs with hemoabdomen.

Atypical Splenic Abscesses Due to Clostridioides difficile.

BACKGROUND Splenic abscess is a rare infectious disease that occurs after bloodstream infection and trauma. It has become more common due to an increase in the number of immunocompromised patients. They typically present with round cystic lesions demonstrated by ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI). Clostridioides difficile (formerly Clostridium difficile) is a well-known cause of pseudomembranous colitis, but extraintestinal manifestations are very rare. To the best of our knowledge, only 9 cases of splenic abscess due to C. difficile have been reported in the literature. CASE REPORT A 90-year-old man presented with weight loss, fever, and abdominal pain. Contrast-enhanced CT revealed splenomegaly with irregular hypodense nodules. Image-guided biopsy or drainage was not performed for a technical reason. MRI showed atypical nodules with mixed high and low signals on both T1- and T2-weighted images, which were inconclusive. A laparoscopic splenectomy was performed, which resulted in partial removal due to severe adhesion of the spleen to the surrounding tissues. Cultures of splenic pus yielded C. difficile, Enterococcus faecium, and Bacteroides fragilis. Pathological examination of the spleen showed widespread abscesses with hemorrhage and necrosis, leading to the diagnosis of splenic abscesses. Intravenous administration of vancomycin, clindamycin or metronidazole was ineffective. He died of fatal arrhythmia 5 months after the initial diagnosis of splenic abscess. CONCLUSIONS Splenic abscess can present with atypical imaging findings owing to chronic inflammation, bleeding, and necrosis. Although polymicrobial, this is the tenth reported case of splenic abscess caused by C. difficile.

Post-Bariatric Splenic Complications; Diagnosis and Treatment. A Systematic Review.

This systematic review intends to evaluate incidence and symptoms of post-bariatric splenic complications as well as best available modalities establishing the diagnosis and management protocols. A systematic literature search was performed in electronic database until March 2022. A total of 41 articles were included on the subject of splenic complications following bariatric/metabolic surgery (BMS). Splenic abscess was the most common splenic complications (44.2%) after BMS and leak was the most common reported etiology of the splenic abscess. Fever and abdominal pain were the most common presenting symptom in all splenic complications and CT scan was the most common diagnostic modality. Splenic complications after BMS are relatively rare but may lead to dangerous consequences. Prompt diagnosis and treatment can prevent potentially life-threatening outcomes.

Sarcopenia, body composition and factors associated with variceal gastrointestinal bleeding and splenectomy in hepatosplenic schistosomiasis mansoni.

BACKGROUND: Sarcopenia is a common complication of cirrhosis and an important predictor of morbimortality. We aimed to determine the prevalence of sarcopenia and its associated factors in hepatosplenic schistosomiasis (HSS) as well as to evaluate whether muscle mass and function are associated with variceal upper gastrointestinal bleeding (VUGIB) and previous splenectomy in subjects without other liver diseases. METHODS: We conducted a cross-sectional study including adults with HSS who underwent clinical, biochemical, anthropometric, muscle strength and physical performance evaluations and were submitted to bioelectrical impedance analysis and abdominal ultrasound. Sarcopenia was diagnosed according to the 2019 European consensus criteria. RESULTS: A total of 66 patients with HSS (62.1% male; mean age 48.8±8.6 y) were included. Overall, six subjects (9.1%) were diagnosed with probable sarcopenia and none had confirmed sarcopenia. Fat-free body mass index (BMI) was independently associated with VUGIB (odds ratio 0.701 [95% confidence interval 0.51 to 0.96]; p=0.025). Compared with patients who did not undergo surgery, individuals who underwent esophagogastric devascularization combined with splenectomy (EGDS) had higher serum lipid levels, fat percentage and frequency of metabolic syndrome, with lower skeletal muscle mass index and hand grip strength. CONCLUSIONS: HSS mansoni seems not to cause sarcopenia. However, a lower fat-free BMI was associated with previous VUGIB and the subgroup of patients who underwent EGDS presented higher lipid levels, fat percentage and frequency of metabolic syndrome and lower muscle mass and function.

Successful management of a case of intestinal Behçet's disease with a splenic abscess by intensified immunosuppressive therapy without splenectomy.

Behçet's disease (BD) is often associated with neutrophilic dermatosis. However, BD is rarely associated with aseptic abscesses in the spleen or liver. A 2-year-old girl presented to our hospital with a 2-week history of fever, abdominal pain, and a skin ulcer on her leg. Each time her skin was punctured with a needle for a blood test or spinal fluid test, she developed intractable aseptic abscesses on her skin. She was diagnosed with intestinal BD based on gastrointestinal endoscopy findings and was treated with prednisolone, mesalazine, and elemental diet therapy. Although these were effective for her colon ulcers, low-grade fever and mild abdominal pain persisted. Abdominal computed tomography revealed a low-density area in the spleen. Although it is recommended to check the contents with puncture drainage, it was difficult due to the risk of bleeding and pathergy. The abscess expanded despite antimicrobial therapy. We discontinued antimicrobial therapy and switched to intensified immunosuppressive therapy for BD [intravenous infliximab (IFX)]. After administration of IFX, the splenic abscess gradually disappeared, and all her symptoms improved. In cases of BD with splenic abscesses resistant to antimicrobial therapy, intensifying immunosuppressive therapy can be expected to shrink the abscesses and avoid splenectomy.

Extensive porto-splenic venous thrombosis postsplenectomy in a sickle cell disease: a rare complication.

Hereditary haemoglobinopathies are common disorders in Oman. The most common haematological disorder among Omani population is sickle cell disease (SCD). The spleen is one of the organs that is affected early in the first decade of life in SCD patients. Splenectomy has shown a high success rate in improving the quality of life in SCD patients, through eliminating acute splenic sequestration crises, thus reducing the need for hospital admission and transfusion requirements. One of the rare complications of splenectomy is porto-splenic vein thrombosis. Multiple factors are responsible for this complication including: thermal and mechanical injury during ligation of splenic hilum, sudden increase in the platelet count and large spleen size. We report a rare case of extensive porto-splenic vein thrombosis that responded to early initiation of anticoagulation with resolution of the thrombosis and recanalisation.

Percutaneous drainage and staged valve replacement followed by laparoscopic splenectomy in infective endocarditis with splenic abscess.

Splenic abscess is a severe complication of infective endocarditis. The need for splenectomy to control prosthetic valve infection remains controversial. Here, we present the case of a 49-year-old man who complained of fever and general fatigue. Blood cultures grew Group G Streptococcus, and intravenous antibiotics were started. Abdominal computed tomography showed splenic abscess; thus, percutaneous drainage was performed. Two-dimensional transthoracic echocardiogram revealed a mobile vegetation on the right coronary cusp of the aortic valve with mild aortic regurgitation. The patient underwent aortic valve replacement using a 23-mm SJM Regent mechanic valve, followed by laparoscopic splenectomy 3 days later. The patient was asymptomatic without recurrence of infection 13 months postoperatively. Current guidelines recommend that splenectomy should be performed first, followed by valve replacement. However, we performed valve surgery first because of the risk of embolism. Depending on the patient's condition, performing splenic drainage and valve replacement first may be considered.

Recurrent aseptic liver abscesses in a patient with Crohn's disease: True infection or a Crohn's flare?

A liver abscess is identified as a rare extraintestinal manifestation of Crohn's disease, with an incidence of approximately 150 in 100,000 patients with this condition. In many of these patients, infectious causes are identified, and the patient's condition is often noted to improve with antibiotics. An aseptic abscess (AA) is an increasingly recognized entity, especially in patients with inflammatory bowel disease, where repetitive evaluations to identify the infectious cause are futile. The average age of diagnosis for an AA is 29 years. The most common site is the spleen, followed by the lymph nodes and then the liver. In this study, we present a unique case of extensive aseptic liver abscesses extending into the pleural cavity in a young patient with Crohn's disease.
