Abrupt elevation of tumor marker levels in a huge splenic epidermoid cyst, a case report.

Epidermoid cyst of the spleen is a rare disease, and relatively few cases were reported by literatures. Most published case reports provided inadequate information on the impact of splenic epidermoid cyst on tumor markers. A 32-year-old woman with a giant splenic epidermoid cyst was reported, for whom the serum concentration of a collection of tumor markers (CA19-9, CEA, CA125, CA242, and CA50) increased abruptly accompanied by left upper abdominal pain for 5 days. After comprehensive preoperative examination and multidisciplinary team discussion, we ruled out any concurrent malignancy and a laparoscopic total splenectomy was performed, during which the splenic cyst spontaneously ruptured unexpectedly. After surgery, the elevated serum tumor marker levels decreased sharply until reaching normal range 3 months later. Learning from the case, we conclude that interval monitoring of serum tumor markers is of critical value for patients with splenic epidermoid cyst. Abrupt elevation of tumor marker levels and abdominal pain may serve as signs of cyst rupture, which is strongly indicative of surgical intervention as soon as possible. Total removal of the splenic cyst is strongly suggested considering the recurrence and malignant potential of the splenic epidermoid cyst.

Laparoscopic splenectomy for sclerosing angiomatoid nodular transformation of the spleen: Report a case.

INTRODUCTION AND IMPORTANCE: Sclerosing angiomatoid nodular transformation (SANT) of the spleen is an extremely rare benign lesion. CASE PRESENTATION: Here, we describe the case of a 52-year-woman who was diagnosed with sclerosing angiomatoid nodular transformation of the spleen. Abdominal contrast-enhanced CT revealed a solid lesion in the splenic hilum that was slowly enhanced between the portal venous and equilibrium phases incidentally. Fluorodeoxyglucose positron emission tomography (FDG-PET) revealed FDG accumulation within the mass, with a maximum standardized uptake value (SUVmax) of 2.57. Based on these findings, the patient was scheduled for laparoscopic splenectomy. The total operating time was 193 min, and the intraoperative blood loss was 20 ml. The resected specimen was 9.0 × 8.4 × 5.6 cm and dark brown in colour with a large central stellate fibrotic scar. CLINICAL DISCUSSION: Pathological examination revealed nodular angioma lesions and the proliferation of fibrotic interstices and inflammatory cells. We could diagnose the SANT by the only HE staining without Immunohistochemical staining. CONCLUSION: Although SANT is a rare benign lesion, which is difficult to definitively diagnose based on preoperative imaging findings alone, it should be considered in cases of solitary splenic lesions, and we recommend performing LS and subsequent histological examination for the diagnosis of this disease.

Management of embolic splenic abscess secondary to aortic valve endocarditis - case report and review of literature.

BACKGROUND: Splenic abscess is a serious complication associated with infective endocarditis. There is still contradicting evidence regarding the optimal treatment pathway including timing of valve intervention and the approach for managing splenic foci. CASE PRESENTATION: We present a case of a hybrid staged approach in which we successfully performed a laparoscopic splenectomy following percutaneous abscess drainage and a delayed aortic valve replacement. CONCLUSIONS: A multidisciplinary teamwork is fundamental in providing optimal care for patients with distant complications associated with infective endocarditis. Our hybrid approach seems safe and feasible.

Prognosis of LSPD versus TIPS for the treatment of esophagogastric variceal bleeding in cirrhosis.

BACKGROUND: This study aimed to compare postoperative complications in patients with esophagogastric variceal bleeding (EVB) who underwent laparoscopic splenectomy combined with pericardial devascularization (LSPD) versus transjugular intrahepatic portosystemic shunt (TIPS) procedures. METHODS: A retrospective collection of medical records was conducted from January 2014 to May 2020 at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. The study included patients from the departments of trauma surgery, interventional radiology, and general surgery who were diagnosed with EVB caused by portal hypertension and treated with LSPD or TIPS. Follow-up data were obtained to assess the occurrence of postoperative complications in both groups. RESULTS: A total of 201 patients were included in the study, with 104 cases in the LSPD group and 97 cases in the TIPS group. There was no significant difference in the 1-year and 3-year post-surgery survival rates between the TIPS and LSPD groups (P = 0.669, 0.066). The 3-year survival rate of Child-Pugh B patients in the LSPD group was higher than TIPS group (P = 0.041). The LSPD group also had a significantly higher rate of freedom from rebleeding at 3-year post-surgery compared to the TIPS group (P = 0.038). Stratified analysis showed no statistically significant difference in the rebleeding rate between the two groups. Furthermore, the LSPD group had a higher rate of freedom from overt hepatic encephalopathy at 1-year and 3-year post-surgery compared to the TIPS group (P = 0.007, < 0.001). The LSPD group also had a lower rate of severe complications at 3-year post-surgery compared to the TIPS group (P = 0.020). CONCLUSION: Compared to TIPS, LSPD does not increase the risk of mortality and rebleeding, while demonstrating fewer complications. In patients classified as Child-Pugh A and B, the use of LSPD for treating EVB is both safe and effective.

Laparoscopic exploration of a wandering spleen in a complex adolescent case with sigmoid volvulus and left-side portal hypertension: a case report.

Wandering spleen (WS) is a rare condition characterized by the hypermobility of the spleen due to the absence or abnormal flexibility of suspensory ligaments. We present a 16-year-old female presented with intermittent abdominal pain, constipation, and a palpable mass in the right iliac fossa. Imaging revealed a WS associated with sigmoid volvulus and portal hypertension. Despite a decade of symptoms, the patient remained undiagnosed. Laparoscopic splenectomy was performed successfully, addressing both WS and sigmoid volvulus. The patient's symptoms resolved, and she was discharged in good condition. This case emphasizes the need for clinical awareness of WS in the differential diagnosis of abdominal pain. It highlights the role of imaging in prompt diagnosis and the necessity of surgical intervention. Our case sheds light on the association of WS with other conditions, providing clinicians with valuable insights for effective management.

Splenic lymphangioma masquerading as splenic abscess managed by laparoscopic splenectomy: A case report.

BACKGROUND: Primary benign splenic tumours are unique and account for < 0.007% of all tumours identified during surgery and autopsy. Splenic lymphangiomas are rarely seen in adults. Splenic lymphangiomas may be asymptomatic, or may present with upper left abdominal pain, splenomegaly, hypersplenism, or splenic rupture with haemorrhagic shock. The clinical and radiological features of these lesions are not specific. This case report serves to remind the clinician to consider the rare but important differential diagnosis of splenic lymphangioma while treating splenic lesions. CASE SUMMARY: We report a case of splenic lymphangioma in a 22-year-old woman who presented with left upper quadrant abdominal pain for three months. Initial investigations were unremarkable; however, computed tomography later revealed multiple splenic micro-abscesses. The patient underwent laparoscopic splenectomy, and histopathological examination revealed splenic lymphangioma. The patient was discharged on postoperative day three. One month after surgery, the abdominal pain resolved completely, with no new complaints. Splenic lymphangiomas present clinically as splenomegaly or left upper quadrant abdominal pain; prompt intervention is necessary for avoiding complications. CONCLUSION: This case report concludes that splenic lymphangiomas should be considered in the differential diagnosis of splenomegaly or left upper quadrant pain, even in adults, because they are amenable to curative treatment. Delays in surgical intervention may lead to severe complications, such as infection, rupture, and hemorrhage. Such lesions can be safely managed with laparoscopy, involving less postoperative pain and early patient discharge with excellent cosmetic outcomes.

[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.

Effects of laparoscopic splenectomy on surgical site wound infection in patients with spleen rupture: A meta-analysis.

A meta-analysis was performed to compare the effects of laparoscopic splenectomy (LS) and open splenectomy (OS) for splenic rupture on postoperative surgical site wound infections and postoperative complications. A comprehensive computerised search was conducted for studies comparing LS with OS for the treatment of splenic rupture in the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases, with the search including studies published in any language between the creation of the databases and August 2023. Two researchers independently screened the literature and extracted the data. Literature quality was assessed using the Newcastle-Ottawa Scale, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Twenty-two studies involving 1545 patients were included. LS was superior to OS in the following aspects: reduced risk of postoperative surgical site wound infection (OR = 0.19, 95% CI: 0.11-0.34, p = 0.000), shortened hospital stay (standardised mean difference = -1.73, 95% CI: -2.05 to -1.40, p = 0.000), and reduced postoperative complication rate (OR = 0.22, 95% CI: 0.16-0.31, p = 0.000). Compared with OS, LS has a lower rate of postoperative wound infection, shorter hospital stay, and reduced rate of postoperative complications. LS is safe and effective for the treatment of splenic rupture and can be promoted clinically.

Laparoscopic Splenectomy and Esophagogastric Devascularization Versus Endoscopic Varices Ligation Plus Laparoscopic Splenectomy in the Treatment of Portal Hypertension.

Background/Aims: To compare laparoscopic splenectomy and esophagogastric devascularization (LSED) with endoscopic variceal ligation (EVL) plus laparoscopic splenectomy (LS) in treating esophagogastric variceal bleeding (EGVB) caused by portal hypertension (PH). Methods: Between January 2015 and May 2022, 87 patients with PH caused by hepatitis B cirrhosis were included in the retrospective study (34 in LSED versus 53 in EVL + LS). Results: The clinical features of both groups were well-matched (P > .05). The EVL+LS group was associated with shorter operation time, lower operative blood loss, faster gastrointestinal (GI) recovery, lower C-reactive protein levels, and shorter hospital stays after operation (P < .05). Operative morbidity was more significant in the LSED group (19 55.9% versus 18 33.9%) (P < .05). On postoperative days 1 and 3, albumin levels were remarkably lower (P < .05) in the LSED group. The mean follow-up was 24.3 months for LSED and 26.5 for EVL+LS. Hematological parameters, hepatic functional status, hepatic hemodynamics, and endoscopy indicated a substantial improvement in both groups (P < .05), but no significant difference was identified (P > .05). There was no discernible difference in the incidence of GI bleeding between the two groups (P > .05). Conclusion: EVL+LS is a safer, simpler, and more minimally invasive treatment of EGVB secondary to PH.

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.

Challenges in the management of a splenic pseudocyst by laparoscopic splenectomy in an adult patient: A case report.

INTRODUCTION AND IMPORTANCE: Splenic cysts are classified as true cysts, or pseudocysts, and larger cysts tend to be symptomatic, requiring management which has evolved to include spleen-sparing procedures to minimize the risk of overwhelming post-splenectomy sepsis (OPSS) Pitiakoudis et al. (2011), Hansen and Moller (2004), Knook et al. (2019) [1-3]. Total splenectomy remains the gold standard management, and the importance of this case is the uncommon spontaneous occurrence of a pseudocyst, and the importance to pre-operatively consent and prepare the patient for total splenectomy would intra-operative conditions not allow for spleen-preserving techniques. CASE PRESENTATION: CS, a 21-year-old lady, had two presentations to the emergency department with left upper quadrant abdominal pain. The only abnormality on assessment was a large splenic cyst on CT scan, which increased in size on re-presentation. She was consented for a splenic cyst fenestration, and for total splenectomy and optimized with vaccines would intra-operative conditions not allow for spleen-sparing. During the operation, the planes between the cyst and spleen parenchyma were ill-defined, and decision was made to proceed with total splenectomy to avoid bleeding complications. She recovered well, and was discharged 5 days post-operatively, and histology confirmed a pseudocyst (Figs. 1 and 2). CLINICAL DISCUSSION: The management of splenic cysts remains difficult and with no clear guidelines to uniform treatment. There are multiple spleen-preserving techniques developed to avoid OPSS (Agha RA, Franchi T, Sohrabi C, Mathew G, for the SCARE Group, 2020 [4]), however management remains individualized and case-specific. CONCLUSION: Pseudocysts can occur without splenic trauma or infarct. Management is case-based, and patients with large symptomatic cysts should be consented and prepared for total splenectomy would conditions not be safe for spleen-preserving interventions.

Clinical efficacy of total laparoscopic splenectomy for portal hypertension and its influence on hepatic hemodynamics and liver function.

BACKGROUND: The liver hemodynamic changes caused by portal hypertension (PH) are closely related to various complications such as gastroesophageal varices and portosys-temic shunts, which may lead to adverse clinical outcomes in these patients, so it is of great clinical significance to find treatment strategies with favorable clinical efficacy and low risk of complications. AIM: To study the clinical efficacy of total laparoscopic splenectomy (TLS) for PH and its influence on hepatic hemodynamics and liver function. METHODS: Among the 199 PH patients selected from October 2016 to October 2020, 100 patients [observation group (OG)] were treated with TLS, while the remaining 99 [reference group (RG)] were treated with open splenectomy (OS). We observed and compared the clinical efficacy, operation indexes [operative time (OT) and intraoperative bleeding volume], safety (intraperitoneal hemorrhage, ascitic fluid infection, eating disorders, liver insufficiency, and perioperative death), hepatic hemodynamics (diameter, velocity, and flow volume of the portal vein system), and liver function [serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), and serum total bilirubin (TBil)] of the two groups. RESULTS: The OT was significantly longer and intraoperative bleeding volume was significantly lesser in the OG than in the RG. Additionally, the overall response rate, postoperative complications rate, and liver function indexes (ALT, AST, and TBil) did not differ significantly between the OG and RG. The hepatic hemodynamics statistics showed that the pre- and postoperative blood vessel diameters in the two cohorts did not differ statistically. Although the postoperative blood velocity and flow volume reduced significantly when compared with the preoperative values, there were no significant inter-group differences. CONCLUSION: TLS contributes to comparable clinical efficacy, safety, hepatic hemodynamics, and liver function as those of OS in treating PH, with a longer OT but lesser intraoperative blood loss.

Hybrid Approach for Treatment of a Symptomatic Giant Splenic Artery Aneurysm.

A 56-year-old female presented with a symptomatic giant fusiform mid-splenic artery aneurysm (7.3 x 6.4 cm). The patient underwent hybrid management of the aneurysm with endovascular embolization of the aneurysm and inflow splenic artery followed by laparoscopic splenectomy with control and division of the outflow vessels. The patient had an uneventful post-operative course. This case demonstrates the safety and efficacy of an innovative, hybrid management of a giant splenic artery aneurysm with endovascular embolization and laparoscopic splenectomy that spares the pancreatic tail.

Pediatric Mini-Invasive Splenectomy Comparing Laparoscopy With or Without Robotic Approach: A Single-Center Study.

Background: The introduction of splenectomy in pediatric robotic surgery programs remains controversial. The aim of this study is to evaluate the feasibility and safety of robotic assisted splenectomy (RAS) in children and compare its outcomes with the laparoscopic splenectomy (LAS). Method: A single institution retrospective study was performed (2011-2020). We used the minimally invasive splenectomy score described by Giza et al. to measure the level of technical difficulty. The data collected for each procedure included its duration, the need for blood transfusion, complications, analgesic use, and the length of hospital stay. A standard univariate analysis is applied. Results: We recorded 41 cases (26 LAS and 15 RAS). The mean age was 11 years [7.00; 13.5]. The operating time was 97 minutes [85.5-108] for LAS and 223 minutes [190-280] for RAS (P < .001). The length of stay was 6.50 days [5.00-8.00] for LAS and 5 days [5.00-5.50] for RAS (P = .055). The cumulative use of level III analgesic was not statically different (P = .29). Two cases of difficult splenectomy were found in each group with comparable performances. In the RAS, we demonstrated the improved outcomes with the progression of the learning curve of a single surgeon. Conclusions: In our experience (as in the literature), RAS remains safe, but offers no additional advantage compared to laparoscopy as the cost and the operating time are higher. Our study has the advantages of having a 9 years long evolving experience, including broad indications in comparison to other pediatric studies.

Isolated splenic metastasis from primary fallopian tube carcinoma and the application of laparoscopic splenectomy: a case report and literature review.

Metastases to the spleen from various non-hematologic malignancies are generally not a common clinical event and usually indicate the late dissemination of disease. Solitary splenic metastases from solid neoplasm are extremely uncommon. Furthermore, solitary metastasis to the spleen from primary fallopian tube carcinoma (PFTC) is extremely rare and has not been reported previously. We report a case of isolated splenic metastasis in a 60-year-old woman, occurring 13 months after a total hysterectomy, a bilateral salpingo-oophorectomy, a pelvic lymphadenectomy, a para-aortic lymphadenectomy, an omentectomy, and an appendectomy were performed for PFTC. The patient's serum tumor marker CA125 was elevated to 49.25 U/ml (N < 35.0 U/ml). An abdominal computed tomography (CT) scan revealed a 4.0 × 3.0 cm low-density lesion in the spleen that was potentially malignant, with no lymphadenectasis or distant metastasis. The patient underwent a laparoscopic exploration, and one lesion was found in the spleen. Then, a laparoscopic splenectomy (LS) confirmed a splenic metastasis from PFTC. The histopathological diagnosis showed that the splenic lesion was a high-differentiated serous carcinoma from PFTC metastasis. The patient recovered for over 1 year, with no tumor recurrence. This is the first reported case of an isolated splenic metastasis from PFTC. This case underlines the importance of serum tumor marker assessment, medical imaging examination, and history of malignancy during follow-up, and LS seems to be the optimal approach for isolated splenic metastasis from PFTC.

Laparoscopic approach in the treatment of splenic angiolipomatous hamartoma: the first report of a case.

Angiolipomatous hamartoma is a benign mesenchymal proliferation of unknown aetiology. Only a few cases have been documented in the published literature. This current case report describes a 57-year-old female patient who was hospitalized for an assessment of a previously radiologically-verified splenic lesion and further treatment. The patient had been surgically treated 10 years previously; a lobectomy of the superior left pulmonary lobe had been performed in order to remove a verified tumour lesion. A complete radiological examination was undertaken, which verified a spleen of a size that was within the physiological range, with a centrally-located lobular tumour lesion. Given the risk of splenic rupture, as well as the fact that the lesion's aetiology was still undetermined, and finally the fact that differential diagnostics indicated the possibility of a metastasis, the patient was treated surgically. Laparoscopic splenectomy, in the treatment of splenic diseases, even rare ones such as this, is not a novelty. Indeed, it needs to be applied as the standard approach, with the well-known benefits that the minimalized approach offers.

Splenic lymphangioma in adult patient treated with laparoscopic splenectomy: A rare case report.

Splenic lymphangioma is a benign cystic tumor that develops as a result of lymphatic vessels' congenital abnormalities. It is a rare condition that mostly occurs in children and young adults. Due to the lack of typical symptoms and signs, splenic lymphangioma is difficult to diagnose and often incidentally revealed during radiological examinations. We report a case of a 55-year-old Asian female, who presented with left upper quadrant abdominal pain in the past 3 days. She had mild upper abdominal tenderness, with no other specific findings. Abdominal contrast material-enhanced computed tomography revealed three hypodense lesions arising from a normal-sized spleen. The histologic findings after laparoscopic splenectomy demonstrated a 3-cm-diameter yellowish-white tumor made up of multiple cystic structures. Primary benign splenic tumors are exceedingly rare, especially in adults over 20. While small lesions are mostly asymptomatic, bigger lesions can cause organ compression or even rupture. Therefore, even in adults with pain in the left upper quadrant abdomen or enlarged spleen, splenic lymphangioma should be taken into account in the differential diagnosis. The case serves as an example of a rare congenital splenic tumor. Treatment of this benign splenic abnormality with laparoscopic splenectomy is a good, safe approach.

Individualized total laparoscopic surgery based on 3D remodeling for portal hypertension: A single surgical team experience.

Background and aims: Portal hypertension (PHT) is common in end-stage cirrhosis, and variceal bleeding is the main complication associated with mortality. Surgery is usually performed in patients with PHT with a high risk of variceal bleeding in China. This study aimed to introduce an individualized and precise total laparoscopic surgical procedure based on 3D remodeling for PHT. Methods: From March 2013 to December 2018, 146 patients with cirrhotic PHT underwent a laparoscopic surgical procedure in our department. An individualized 3D remodeling evaluation was carried out for surgical planning. Results: The operation time was 319.96 ± 91.53 min. Eight of 146 patients were converted to open surgery. Acute portal vein system thrombosis occurred in 10 patients (6.85%). During the first year, 11 patients (8.15%) experienced rebleeding and two (1.48%) died. 18 patients (13.33%) experienced rebleeding and three died, giving a 3-year mortality rate of 3.66%. Compared with preoperatively, the portal vein showed significant postoperative decreases in diameter, flow velocity, and flow amount, while the hepatic artery showed significant postoperative increases in diameter, flow velocity, and flow amount. A 3D liver volume evaluation found that 19 of 21 patients had a significantly increased liver volume postoperatively, and a significantly decreased MELD score. Conclusion: This retrospective study introduced a safe, feasible, and effective individualized surgical procedure. Our results show that this surgical treatment may not only act as an effective symptomatic treatment for PHT to prevent esophageal and gastric hemorrhage, but also as an etiological treatment to increase liver function and long-term survival.
