RESUMO

OBJECTIVE: The objective of this study was to investigate the correlation between spleen density and the prognostic outcomes of patients who underwent curative resection for colorectal cancer (CRC). METHODS: The clinical data of patients who were diagnosed with CRC and underwent radical resection were retrospectively analyzed. Spleen density was determined using computed tomography. Analysis of spleen density in relation to overall survival (OS) and disease-free survival (DFS) utilizing the Kaplan-Meier method. Univariate and multivariate Cox regression models were used to screen for independent prognostic factors, and a nomogram was constructed to predict OS and DFS. Moreover, internally validated using a bootstrap resamplling method. RESULTS: Two hundred twelve patients were included, of whom 23 (10.85%) were defined as having a diffuse reduction of spleen density (DROSD) based on diagnostic cutoff values (spleen density≦37.00HU). Kaplan-Meier analysis indicated that patients with DROSD had worse OS and DFS than those non-DROSD (P < 0.05). Multivariate Cox regression analysis revealed that DROSD, carbohydrate antigen 199 (CA199) > 37 U/mL, tumor node metastasis (TNM) stage III-IV, laparoscopy-assisted operation and American Society of Anesthesiology (ASA) score were independent risk factors for 3-year DFS. DROSD, CA199 > 37 U/mL, TNM stage III-IV, hypoalbuminemia, laparoscopy-assisted operation and ASA score were chosen as predictors of for 3-year OS. Nomograms showed satisfactory accuracy in predicting OS and DFS using calibration curves, decision curve analysis and bootstrap resamplling method. CONCLUSION: Patients with DROSD who underwent curative resection have worse 3-year DFS and OS. The nomogram demonstrated good performance, particularly in predicting 3-year DFS with a net clinical benefit superior to well-established risk calculator.

RESUMO

BACKGROUND: In the early 2000s, substantial variations were reported in the management of pediatric patients with blunt splenic injury (BSI). The purpose of this study was to assess the recent trends and disparities between different types of trauma centers. We hypothesized that there would be persistent disparities despite decreased trends in the rate of splenectomy. METHODS: This is a retrospective cohort study using the American College of Surgeons Trauma Quality Improvement Program database. We included patients (age ≤18 years) with high-grade BSI (Abbreviated Injury Scale 3-5) between 2014 and 2021. The patients were divided into three groups based on trauma center types (adult trauma centers [ATCs], mixed trauma centers [MTCs], and pediatric trauma centers [PTCs]). The primary outcome was the splenectomy rate. Logistic regression was performed to evaluate the association between trauma center types and clinical outcomes. Additionally, the trends in the rate of splenectomy at ATCs, MTCs, and PTCs were evaluated. RESULTS: A total of 6601 patients with high-grade BSI were included in the analysis. Overall splenectomy rates were 524 (17.5%), 448 (16.3%), and 32 (3.7%) in the ATC, MTC, and PTC groups, respectively. ATCs and MTCs had significantly higher splenectomy rates compared to PTCs (ATCs: OR = 5.72, 95%CI = 3.78-8.67, and p < 0.001 and MTCs: OR = 4.50, 95%CI = 2.97-6.81, and p < 0.001), while decreased trends in the splenectomy rates were observed in ATCs and MTCs (ATCs: OR = 0.92, 95%CI = 0.87-0.97, and p = 0.003 and MTCs: OR = 0.92, 95%CI = 0.87-0.98, and p = 0.013). CONCLUSIONS: This study suggested persistent disparities between different trauma center types in the management of children with high-grade BSI.

RESUMO

This report describes the case of a 32-year-old woman with ectopic pregnancy in the spleen, which was complicated by active bleeding. The patient complained of intermittent pain in her left side and lower abdomen that lasted several days. The serum beta-human chorionic gonadotropin (ß-hCG) was increased, but no intrauterine gestational sac was found via transvaginal sonography. A computed tomography (CT) examination revealed the presence of a heterogeneous structure in the left peritoneal cavity, inferior to the spleen; signs of active extravasation; and a large amount of hemorrhagic fluid in the pelvis. An angiography examination also showed slow active extravasation from a small artery that branches off at the lower pole of the spleen. Coil embolization was performed. Splenic ectopic pregnancy can be managed by minimally invasive methods in carefully selected patients.

RESUMO

Colonoscopy is an integral part of the lower bowel care and is generally considered a potentially safe diagnostic and therapeutic procedure performed as a daycare outpatient procedure. Colonoscopy is associated with different complications that are not limited to adverse events related to the bowel preparation solutions used, the sedatives used, but to the procedure related as well including bleeding and perforation. Injuries to the extra-luminal abdominal organs during colonoscopy are uncommon, however, serious complications related to the procedure have been reported infrequently in the literature. Life threatening injuries to the spleen, liver, pancreas, mesentery, and urinary bladder have been reported as early as in mid-1970s. These injuries should not be overlooked by clinicians and endoscopists. Steadily increasing abdominal pain, abdominal distension, and hemodynamic instability in absence of rectal bleeding should raise the possibility of severe organ injury. Splenic and hepatic injury following colonoscopy are usually serious and may be life threatening. Although conservative management may help, yet they usually need interventional radiology or surgical intervention. Acute pancreatitis following colonoscopy is usually mild and is mostly managed conservatively. The mechanism of abdominal organ injuries during colonoscopy is not fully understood, however many risk factors have been identified, which can be classified as- organ related, procedure related, and local abdominal factors. Difficult colonoscopy and prior intra-abdominal adhesions are probably the most relevant risk factors for these injuries. Left lateral position, avoidance of looping and excessive force during the procedure would probably reduce the risk of such injuries.

RESUMO

BACKGROUND: Thromboprophylaxis after blunt splenic trauma is complicated by the risk of bleeding, but the risk after angioembolization is unknown. We hypothesized that earlier thromboprophylaxis initiation was associated with increased bleeding complications without mitigating venous thromboembolism events. METHODS: All blunt trauma patients who underwent splenic angioembolization within 24 hours of arrival were identified from the American College of Surgeons Trauma Quality Improvement Program datasets from 2017 to 2019. Cases with <24-hour length of stay, other serious injuries, and surgery before angioembolization were excluded. Venous thromboembolism was defined as deep vein thrombosis or pulmonary embolism. Bleeding complications were defined as splenic surgery, additional embolization, or blood transfusion after thromboprophylaxis initiation. Data were compared with χ2 analysis and multivariate logistic regression at P < .05. RESULTS: In 1,102 patients, 84% had American Association for the Surgery of Trauma grade III to V splenic injuries, and 73% received thromboprophylaxis. Splenic surgery after angioembolization was more common in those with thromboprophylaxis initiation within the first 24 hours (5.7% vs 1.7%, P = .007), whereas those with the initiation of thromboprophylaxis after 72 hours were more likely to have a pulmonary embolism (2.3% vs 0.2%, P = .001). Overall, venous thromboembolism increased considerably when thromboprophylaxis was initiated after day 3. In multivariate analysis, time to thromboprophylaxis initiation was associated with bleeding (odds ratio 0.74 [95% confidence interval 0.58-0.94]) and venous thromboembolism complications (odds ratio 1.5 [95% confidence interval 1.20-1.81]). CONCLUSION: This national study evaluates bleeding and thromboembolic risk to elucidate the specific timing of thromboprophylaxis after splenic angioembolization. Initiation of thromboprophylaxis between 24 and 72 hours achieves the safest balance in minimizing bleeding and venous thromboembolism risk, with 48 hours particularly serving as the ideal time for protocolized administration.

RESUMO

OBJECTIVE: This study aims to investigate determinants impacting the surgical management of splenic trauma in paediatric patients by scrutinizing age distribution, etiological factors and concomitant injuries. The analysis seeks to establish a foundation for delineating optimal operative timing. METHODS: A cohort of 262 paediatric cases presenting with splenic trauma at our institution from January 2011 to December 2021 underwent categorization into either the conservative or operative group. RESULTS: Significantly disparate attributes between the two groups included age, time of presentation, blood pressure, haemoglobin levels, blood transfusion requirements, thermal absorption, American Association for the Surgery of Trauma (AAST) classification and associated injuries. Logistic regression analysis revealed age, haemoglobin levels, AAST classification and blood transfusion as autonomous influencers of surgical intervention (OR = 1.024, 95% CI: 1.011-1.037; OR = 1.067, 95% CI: 1.01-1.127; OR = 0.2760, 95% CI: 0.087-0.875; OR = 7.873, 95% CI: 2.442-25.382; OR = 0.016, 95% CI: 0.002-0.153). The AAST type and age demonstrated areas under the receiver operating characteristic (ROC) curve of 0.782 and 0.618, respectively. CONCLUSION: Age, haemoglobin levels, AAST classification and blood transfusion independently influence the decision for surgical intervention in paediatric patients with splenic trauma. Age and AAST classification emerge as viable parameters for assessing and prognosticating the likelihood of surgical intervention in this patient cohort.

RESUMO

BACKGROUND: The spleen plays a significant role in the clearance of circulating microorganisms. Sequelae of splenectomy, especially immunodeficiency, can have a deleterious effect on a patient's health and even lead to death. Hence, splenectomy should be avoided and spleen preservation during elective surgery has become a treatment goal. However, this cannot be achieved in every patient due to intraoperative technical difficulties or oncological reasons. Autogenic splenic implantation (ASI) is currently the only possible way to preserve splenic function when a splenectomy is necessary. Experience largely stems from trauma patients with a splenic rupture. Splenic immune function can be measured by the body's clearing capacity of encapsulated bacteria. The aim of this study is to assess the splenic immune function after ASI was performed during minimally invasive (laparoscopic or robotic) distal pancreatectomy with splenectomy. METHODS: This is the protocol for a multicentre, randomized, open-labelled trial. Thirty participants with benign or low-grade malignant lesions of the distal pancreas requiring minimally invasive distal pancreatectomy and splenectomy will be allocated to either additional intraoperative ASI (intervention) or no further intervention (control). An additional 15 patients who will undergo spleen-preserving distal pancreatectomy serve as the control group with normal splenic function. Six months postoperatively, after assumed restoration of splenic function, patients will be given a Salmonella typhi (Typhim Vi™) vaccine. The Salmonella typhi vaccine is a polysaccharide vaccine. The specific antibody titres immediately before and 4 to 6 weeks after vaccination will be measured. The ratio between pre- and post-vaccination antibody count is the primary outcome measure and secondary outcome measures include intraoperative details, length of hospital stay, 30-day mortality and morbidity. DISCUSSION: This study will investigate the splenic immune function of patients who undergo ASI during minimally invasive distal pancreatectomy with splenectomy. The splenic immune function will be measured using the surrogate outcome of specific antibody titre after vaccination with a Salmonella typhi vaccine. The results will reveal details about splenic function after ASI and guide further treatment options for patients when a splenectomy cannot be avoided. It might eventually lead to a new standard of care making sometimes more demanding and time-consuming spleen-preserving procedures redundant. TRIAL REGISTRATION: International Standard Randomized Controlled Trials Number (ISRCTN) ISRCTN10171587. Prospectively registered on 18 February 2019.

RESUMO

Surgical removal of the thyroid gland (TG) for treating thyroid disorders leaves the patients on lifelong hormone replacement that partially compensates the physiological needs, but regenerating TG is challenging. Here, an approach is reported to regenerate TG within the spleen for fully restoring the thyroid's functions in mice, by transplanting thyroid tissue blocks to the spleen. Within 48 h, the transplanted tissue efficiently revascularizes, forming thyroid follicles similar to the native gland after 4 weeks. Structurally, the ectopically generated thyroid integrates with the surrounding splenic tissue while maintaining its integrity, separate from the lymphatic tissue. Functionally, it fully restores the native functions of the TG in hormone regulation in response to physiological stimuli, outperforming the established method of oral levothyroxine therapy in maintaining systemic homeostasis. The study demonstrates the full restoration of thyroid functions post-thyroidectomy by intrasplenic TG regeneration, providing fresh insights for designing novel therapies for thyroid-related disorders.

RESUMO

BACKGROUND: Splenic injury due to colonoscopy is rare, but has high mortality. While historically treated conservatively for low-grade injuries or with splenectomy for high-grade injuries, splenic artery embolisation is increasingly utilised, reflecting modern treatment guidelines for external blunt trauma. This systematic review evaluates outcomes of published cases of splenic injury due to colonoscopy treated with splenic artery embolisation. METHODS: A systematic review was performed of published articles concerning splenic injury during colonoscopy treated primarily with splenic artery embolisation, splenectomy, or splenorrhaphy from 1977 to 2022. Datapoints included demographics, past surgical history, indication for colonoscopy, delay to diagnosis, treatment, grade of injury, splenic artery embolisation location, splenic preservation (salvage), and mortality. RESULTS: The 30 patients treated with splenic artery embolisation were of mean age 65 (SD 9) years and 67% female, with 83% avoiding splenectomy and 6.7% mortality. Splenic artery embolisation was proximal to the splenic hilum in 81%. The 163 patients treated with splenectomy were of mean age 65 (SD 11) years and 66% female, with 5.5% mortality. Three patients treated with splenorrhaphy of median age 60 (range 59-70) years all avoided splenectomy with no mortality. There was no difference in mortality between splenic artery embolisation and splenectomy cohorts (p = 0.81). CONCLUSIONS: Splenic artery embolisation is an effective treatment option in splenic injury due to colonoscopy. Given the known benefits of splenic salvage compared to splenectomy, including preserved immune function against encapsulated organisms, low cost, and shorter hospital length of stay, embolisation should be incorporated into treatment pathways for splenic injury due to colonoscopy in suitable patients.

RESUMO

INTRODUCTION: Laparoscopic spleen-preserving distal pancreatectomy (LSDP) is widely performed to treat benign and low-grade malignant diseases. Although preservation of splenic vessels may be desirable considering the risk of postoperative complications, it is sometimes difficult due to tumor size, inflammation, and proximity of the tumor and splenic vessels. Herein, we present the first case of LSDP with splenic artery resection and splenic vein preservation. MATERIALS AND SURGICAL TECHNIQUE: A 40-year-old woman with a pancreatic tumor was referred to our hospital. Contrast-enhanced computed tomography (CT) revealed a tumor in the pancreatic tail that was in contact with the splenic artery and distant from the splenic vein. The splenic artery and vein were separated from the pancreas near the dissection line. The splenic artery was resected after pancreatic dissection using a linear stapler. After the pancreatic tail was separated from the splenic hilum while preserving the splenic vein, the distal side of the splenic artery was resected, and the specimen was removed. The postoperative course was uneventful and the patient was discharged on postoperative Day 9. Four months after surgery, postoperative follow-up CT findings showed neither splenic infarction nor gastric varices. DISCUSSION: This technique is an alternative method of splenic preservation when there is no attachment of the tumor to the splenic vein or uncontrolled expected bleeding of the splenic artery using the Kimura technique.

RESUMO

BACKGROUND: The gastrohepatic ligament approach is a form of robot-assisted spleen-preserving distal pancreatectomy (SPDP).1,2 This approach does not require omentum transection, peri-splenic dissection, or stomach traction. METHODS: Considering the advantages of preserving collateral pathways around the spleen, the authors performed the gastrohepatic ligament approach in laparoscopic SPDP while preserving splenic vessels (LSPDP), with specific modifications for laparoscopic surgery. The following surgical technique was performed. First, the gastrohepatic ligament was divided extensively, and all subsequent procedures were performed through the gastrohepatic ligament route. The superior and inferior borders of the pancreas then were dissected to encircle the common hepatic and splenic arteries with vessel loops and to expose the superior mesenteric vein (SMV) and portal vein. After taping of the pancreas on the SMV, the pancreas was divided using a linear stapler. Next, the pancreas was dissected from proximal to distal with preservation of the splenic vessels. Re-taping and traction of the splenic vessels and pancreas could facilitate the dissection of the pancreas body, especially at the splenic hilum. The appropriate counter traction using traction tapes allowed efficient laparoscopic procedures. The LSPDP was performed for three patients, including one obese patient (body mass index, 36 kg/m2) and two patients with an anomalous left hepatic artery branching from the left gastric artery. RESULTS: The mean operation time was 186 min, and the intraoperative blood loss was 37 mL. CONCLUSION: The gastrohepatic ligament approach could be an option for performing LSPDP with the counter traction technique for low-grade malignant tumors.

RESUMO

AIMS: To evaluate comparative outcomes of laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and laparoscopic distal pancreatectomy with splenectomy (LDPS). METHODS: A systematic search of multiple electronic data sources and bibliographic reference lists were conducted. Comparative studies reporting outcomes of LSPDP and LDPS were considered followed by evaluation of the associated risk of bias according to ROBINS-I tool. Perioperative complications, clinically important postoperative pancreatic fistula (POPF), infectious complications, blood loss, conversion to open, operative time and duration of hospital stay were the investigated outcome parameters. RESULTS: Nineteen studies were identified enrolling 3739 patients of whom 1860 patients underwent LSPDP and the remaining 1879 patients had LDPS. The patients in the LSPDP and LDPS groups were of comparable age (p = 0.73), gender (p = 0.59), and BMI (p = 0.07). However, the patient in the LDPS group had larger tumour size (p = 0.0004) and more malignant lesions (p = 0.02). LSPDP was associated with significantly lower POPF (OR:0.65, p = 0.02), blood loss (MD:-28.30, p = 0.001), and conversion to open (OR:0.48, p < 0.0001) compared to LDPS. Moreover, it was associated with significantly shorter procedure time (MD: -22.06, p = 0.0009) and length of hospital stay (MD: -0.75, p = 0.005). However, no significant differences were identified in overall perioperative (OR:0.89, p = 0.25) or infectious (OR:0.67, p = 0.05) complications between two groups. CONCLUSIONS: LSPDP seems to be associated with lower POPF, bleeding and conversion to open compared to LDPS in patients with small-sized benign tumours. Moreover, it may be quicker and reduce hospital stay. Nevertheless, such advantages are of doubtful merit about large-sized or malignant tumours. The available evidence is subject to confounding by indication.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Treatment of splenic trauma is currently based on non-surgical treatment or the use of interventional radiology. The conservative surgery of the spleen in splenic trauma remains marginal. OBJECTIVE: To analyze the safety and efficacy of conservative surgical treatment in splenic trauma. METHOD: A retrospective study was performed over a 16-year period with the intention of recording the diagnostic and therapeutic attitude in a second level hospital, focusing on patients who received conservative splenic surgical treatment for splenic trauma, excluding splenectomies and non-surgical treatment. RESULTS: 110 patients presented splenic trauma. Spleen-sparing surgery was performed in 15 patients. The grades of splenic lesions were: 1 patient with grade I, 1 patient with grade II, 7 patients with grade III and 6 patients with grade IV. Surgical treatment was splenorrhaphy in 5 patients (33%), hemostatic agents and polyglycolic acid mesh in 4 (26%), partial splenectomy with placement of polyglycolic acid mesh in 3 (20%), partial splenectomy in 2 (13%), and electrocautery in 1 (6%). None of the patients initially treated with conservative surgery required posterior splenectomy and no patient died. CONCLUSION: We provide evidence supporting the usefulness and safety of conservative splenic surgery in splenic trauma, which would have its place in grades II, III and IV trauma in health centers that do not have urgent interventional radiology.


ANTECEDENTES: El tratamiento del traumatismo esplénico se basa en medidas conservadoras no quirúrgicas o en el uso de radiología intervencionista. La cirugía conservadora del bazo en el traumatismo esplénico sigue siendo inusual. OBJETIVO: El análisis de seguridad y eficacia del tratamiento quirurgico conservador en el traumatismo esplénico. MÉTODO: Se realizó un estudio retrospectivo durante un período de 16 años con la intención de registrar la actitud diagnóstica y terapéutica en un hospital de segundo nivel, enfocándose en los pacientes que recibieron tratamiento quirúrgico conservador esplénico por traumatismo esplénico, excluyendo esplenectomías y tratamientos no quirúrgicos. RESULTADOS: 110 pacientes presentaron traumatismo esplénico. La cirugía conservadora esplénica se realizó en 15 pacientes. Los grados de lesiones esplénicas fueron: 1 paciente con grado I, 1 paciente con grado II, 7 pacientes con grado III y 6 pacientes con grado IV. El tratamiento quirúrgico fue esplenorrafia en 5 pacientes (33%), agentes hemostáticos y malla de ácido poliglicólico en 4 (26%), esplenectomía parcial con colocación de malla de ácido poliglicólico en 3 (20%), esplenectomía parcial en 2 (13%) y hemostasia con electrocauterio en 1 (6%). Ninguno de los pacientes tratados inicialmente con cirugía conservadora requirió esplenectomía posterior y ningún paciente falleció. CONCLUSIONES: La cirugía conservadora esplénica puede ser útil y segura en traumatismos esplénicos, la cual tendría su lugar en traumatismos de grados II, III y IV en centros hospitalarios en los que no se cuente con radiología intervencionista urgente.

RESUMO

Background: Pancreatic trauma is an uncommon injury that occurs usually in a young population and is frequently overlooked and not readily appreciated on initial examination. Nowadays, the diagnosis and management of pancreatic trauma are still controversial, and there is no gold standard for the treatment. The aim of this study is to describe our experience in the management of blunt pancreatic trauma with a laparoscopic approach and review the literature on laparoscopic management of pancreatic trauma. Methods: A systematic literature review was performed, and 40 cases were reported and analysed; 10 cases were excluded because the complete data were not retrievable. We also reported our experience with the case of an 18-year-old male diagnosed with a deep laceration of the pancreas between body and tail, involving the main pancreatic duct, and with a concomitant hematoma. The patient underwent exploratory laparoscopy with abdominal toilet, necrosectomy, and suture of main pancreatic duct; the total blood loss was less than 200 ml, and the total operative time was 180 minutes. The patient recovered uneventfully and was discharged on the 6th postoperative day. Results: 30 patients with pancreatic trauma, 10 adults and 20 pediatrics (mean age 28.2 years and 10.5 years), underwent a total laparoscopic approach: 2 distal pancreatic-splenectomy, 22 spleen-preserving distal pancreatectomy, and 6 laparoscopic drainage. The mean operative time for the adult and pediatric populations was 160.6 and 214.5 minutes, the mean estimated blood loss was 400 ml and 75 ml, and the mean hospital stay was 14.9 and 9 days, respectively. Conclusion: Laparoscopic management for pancreatic trauma can be considered feasible and safe when performed by an experienced laparoscopic pancreatic team, and in such a setting, it can be considered a viable alternative to open surgery, offering the well-known benefits of minimally invasive surgery.
