Abstract
Importance The spleen is often removed in laparotomy after traumatic abdominal injury, with little effort made to preserve the spleen. Objective To explore the association of surgical management (splenic repair vs splenectomy) with outcomes in patients with traumatic splenic injuries undergoing laparotomy and to determine whether splenic repair is associated with lower mortality compared with splenectomy. Design, Setting, and Participants This is a trauma registry-based cohort study using the American College of Surgeons Trauma Quality Improvement Program database from January 2013 to December 2019. Participants included adult patients with severe splenic injuries (Abbreviated Injury Scale [AIS] grades 3-5) undergoing laparotomy after traumatic injury within 6 hours of admission. Data analysis was performed from April to August 2023. Exposures Splenic repair vs splenectomy in patients with severe traumatic splenic injury. Main Outcomes and Measures The primary outcome was in-hospital mortality. Outcomes were compared using different statistical approaches, including 1:1 exact matching with consecutive conditional logistic regression analysis as the primary analysis and multivariable logistic regression, propensity score matching, and inverse-probability weighting as sensitivity analyses. Results A total of 11 247 patients (median [IQR] age, 35 [24-52] years; 8179 men [72.7%]) with a severe traumatic splenic injury undergoing laparotomy were identified. Of these, 10 820 patients (96.2%) underwent splenectomy, and 427 (3.8%) underwent splenic repair. Among patients who underwent an initial splenic salvage procedure, 23 (5.3%) required a splenectomy during the subsequent hospital stay; 400 patients with splenic preservation were matched with 400 patients who underwent splenectomy (matched for age, sex, hypotension, trauma mechanism, AIS spleen grade, and AIS groups [0-2, 3, and 4-5] for head, face, neck, thorax, spine, and lower and upper extremity). Mortality was significantly lower in the splenic repair group vs the splenectomy group (26 patients [6.5%] vs 51 patients [12.8%]). The association of splenic repair with lower mortality was subsequently verified by conditional regression analysis (adjusted odds ratio, 0.4; 95% CI, 0.2-0.9; P = .03). Multivariable logistic regression, propensity score matching, and inverse-probability weighting confirmed this association. Conclusions and Relevance In this retrospective cohort study, splenic repair was independently associated with lower mortality compared with splenectomy during laparotomy after traumatic splenic injury. These findings suggest that efforts to preserve the spleen might be indicated in selected cases of severe splenic injuries.

Clinical Outcomes of Splenic Artery Embolization Versus Splenectomy in the Management of Hemodynamically Stable High-Grade Blunt Splenic Injuries: A National Analysis. J Surg Res 2024; 300:221-230. [PMID: 38824852 DOI: 10.1016/j.jss.2024.05.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 04/28/2024] [Accepted: 05/08/2024] [Indexed: 06/04/2024]
Abstract
INTRODUCTION This study aims to compare the outcomes of splenic artery embolization (SAE) versus splenectomy in adult trauma patients with high-grade blunt splenic injuries. METHODS This retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program database (2017-2021) compared SAE versus splenectomy in adults with blunt high-grade splenic injuries (grade ≥ IV). Patients were stratified first by hemodynamic status then splenic injury grade. Outcomes included in-hospital mortality, intensive care unit length of stay (ICU-LOS), and transfusion requirements at four and 24 h from arrival. RESULTS Three thousand one hundred nine hemodynamically stable patients were analyzed, with 2975 (95.7%) undergoing splenectomy and 134 (4.3%) with SAE. One thousand eight hundred sixty five patients had grade IV splenic injuries, and 1244 had grade V. Patients managed with SAE had 72% lower odds of in-hospital mortality (odds ratio [OR] 0.28; P = 0.002), significantly shorter ICU-LOS (7 versus 9 d, 95%, P = 0.028), and received a mean of 1606 mL less packed red blood cells at four h compared to those undergoing splenectomy. Patients with grade IV or V injuries both had significantly lower odds of mortality (IV: OR 0.153, P < 0.001; V: OR 0.365, P = 0.041) and were given less packed red blood cells within four h when treated with SAE (2056 mL versus 405 mL, P < 0.001). CONCLUSIONS SAE may be a safer and more effective management approach for hemodynamically stable adult trauma patients with high-grade blunt splenic injuries, as demonstrated by its association with significantly lower rates of in-hospital mortality, shorter ICU-LOS, and lower transfusion requirements compared to splenectomy.

Abstract
BACKGROUND In major trauma, lesions of the parenchymatous organs are subject of a controversy as regards the choice between an operative management (OM) in the operating room and a non-operative management (NOM) associated or not with angiography/angioembolization (AG/AE). METHODS Retrospective study of all consecutive data of patients coded as "traumatic pathology" in the period between 2011 and 2021. Were enrolled 13740 entries of adult patients with abdominal injuries, including at least: either hepatic or splenic or renal injury of AAST-OIS I. The primary outcome was to establish the rate of efficacy, respectively of OM and NOM. The secondary outcome is to analyze General (CG) and Specific (CS) complications, mean ward and intensive care unit (ICU) hospital stays. RESULTS One hundred sixty-two patients were included with 89 splenic injuries, 70 hepatic and 50 renal lesions; 35 treated with OM and 127 with NOM±AG/AE. The CGs registered in OM patients are seven (20%); seven SCs (20%); four GCs+SCs (11.4%). The average hospital stay was 24.91 days; mean ICU hospital stay of 10.74; five deaths. The CGs registered are 22 (17%); 12 SCs (9.4%); three GCs+SCs (2.3%). Average hospital stays 18 days; mean ICU hospital stay of 3.15; 6 deaths. Failure of the NOM strategy was recorded in nine patients with a success rate of 92.91%. CONCLUSIONS In OM the presence of numerous high-grade lesions leads to a rapid stabilization. The NOM has reduced the hospital stay and UTI hospitalization in a feasible and safe way in selected CT.

Abstract
Spleen-preserving distal pancreatectomy offers an alternative surgical approach to the traditional distal pancreatectomy combined with splenectomy for removing benign and low-grade malignant lesions in the distal pancreas, avoiding complications associated with splenectomy. This procedure can be accomplished either by resecting and ligating the splenic vessels (Warshaw technique) or by preserving them (Kimura technique). Currently, the widespread use of minimally invasive surgery has established laparoscopic and robotic approaches for spleen-preserving distal pancreatectomy as valid and safe options for treating such conditions. Our protocol aims to describe how the Warshaw and Kimura techniques of spleen-preserving distal pancreatectomy can be performed robotically. The first patient is a 36-year-old female with a neuroendocrine tumor (NET) in the pancreatic body who underwent a spleen-preserving distal pancreatectomy with the ligation of the splenic vessels (WT). The second patient is a 76-year-old male with chronic pancreatitis presenting with a dilated main pancreatic duct in the tail of the pancreas who underwent a spleen-preserving distal pancreatectomy with a vessel-preserving approach (KT).

World J Gastroenterol 2024; 30:3314-3325. [PMID: 39086747 PMCID: PMC11287416 DOI: 10.3748/wjg.v30.i27.3314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 05/24/2024] [Accepted: 06/17/2024] [Indexed: 07/11/2024] Open
Abstract
BACKGROUND Liver stiffness (LS) measurement with two-dimensional shear wave elastography (2D-SWE) correlates with the degree of liver fibrosis and thus indirectly reflects liver function reserve. The size of the spleen increases due to tissue proliferation, fibrosis, and portal vein congestion, which can indirectly reflect the situation of liver fibrosis/cirrhosis. It was reported that the size of the spleen was related to posthepatectomy liver failure (PHLF). So far, there has been no study combining 2D-SWE measurements of LS with spleen size to predict PHLF. This prospective study aimed to investigate the utility of 2D-SWE assessing LS and spleen area (SPA) for the prediction of PHLF in hepatocellular carcinoma (HCC) patients and to develop a risk prediction model. AIM To investigate the utility of 2D-SWE assessing LS and SPA for the prediction of PHLF in HCC patients and to develop a risk prediction model. METHODS This was a multicenter observational study prospectively analyzing patients who underwent hepatectomy from October 2020 to March 2022. Within 1 wk before partial hepatectomy, ultrasound examination was performed to measure LS and SPA, and blood was drawn to evaluate the patient's liver function and other conditions. Least absolute shrinkage and selection operator logistic regression and multivariate logistic regression analysis was applied to identify independent predictors of PHLF and develop a nomogram. Nomogram performance was validated further. The diagnostic performance of the nomogram was evaluated with receiver operating characteristic curve compared with the conventional models, including the model for end-stage liver disease (MELD) score and the albumin-bilirubin (ALBI) score. RESULTS A total of 562 HCC patients undergoing hepatectomy (500 in the training cohort and 62 in the validation cohort) were enrolled in this study. The independent predictors of PHLF were LS, SPA, range of resection, blood loss, international normalized ratio, and total bilirubin. Better diagnostic performance of the nomogram was obtained in the training [area under receiver operating characteristic curve (AUC): 0.833; 95% confidence interval (95%CI): 0.792-0.873; sensitivity: 83.1%; specificity: 73.5%] and validation (AUC: 0.802; 95%CI: 0.684-0.920; sensitivity: 95.5%; specificity: 52.5%) cohorts compared with the MELD score and the ALBI score. CONCLUSION This PHLF nomogram, mainly based on LS by 2D-SWE and SPA, was useful in predicting PHLF in HCC patients and presented better than MELD score and ALBI score.

Abstract
INTRODUCTION Venous thromboembolism (VTE) continues to be a major cause of morbidity in trauma. It is unclear whether the type of hemorrhage control procedure (i.e., splenectomy versus angioembolization) is associated with an increased risk of VTE. We hypothesize that hemodynamically stable patients undergoing angioembolization for blunt high-grade splenic injuries have lower rates of VTE compared to those undergoing splenectomy. METHODS The American College of Surgeons Trauma Quality Program dataset from 2017 to 2019 was queried to identify all patients with American Association for the Surgery of Trauma grade 3-5 blunt splenic injuries. Outcomes including VTE rates were compared between those who were managed with splenectomy versus angioembolization. Propensity score matching (1:1) was performed adjusting for age, sex, initial vital signs, Injury Severity Score, and splenic injury grade. RESULTS The analysis included 4698 matched patients (splenectomy [n = 2349] and angioembolization [n = 2349]). The median (interquartile range) age was 41 (27-58) years and 69% were male. Patients were well matched between groups. Angioembolization was associated with significantly lower VTE than splenectomy (2.2% versus 3.4%, P = 0.010) despite less use of VTE chemoprophylaxis (70% versus 80%, P < 0.001), as well as a relative delay in initiation of chemoprophylaxis (44 h versus 33 h, P < 0.001). Hospital and intensive care unit length of stay and mortality were also significantly lower in the angioembolization group. CONCLUSIONS Angioembolization is associated with a significantly lower incidence of VTE than splenectomy. Thus, angioembolization should be considered for initial management of hemodynamically stable patients with high-grade blunt splenic injuries in whom laparotomy is not otherwise indicated.

Abstract
BACKGROUND The objective of this study was to identify factors associated with the use of spleen-conserving surgeries, as well as patient outcomes, on a national scale. METHODS This retrospective cohort study (2010-2015) included patients (age≥16 years) with splenic injury in the National Trauma Data Bank. Patients who received a total splenectomy or a spleen-conserving surgery were compared for demographics and clinical outcomes. RESULTS During the study period, 18,425 received a total splenectomy and 1,825 received a spleen-conserving surgery. Total splenectomy was more likely to be performed for patients with age>65 (odds ratio [OR]: 0.63, p < 0.001), systolic blood pressure<90 (OR: 0.63, p < 0.001), heart rate>120 (OR: 0.83, p = 0.007), and high-grade injuries (OR: 0.18, p < 0.001). Penetrating trauma patients were more likely to undergo a spleen-conserving surgery (OR: 3.31, p < 0.001). The use of spleen-conserving surgery was associated with a lower risk of pneumonia (OR: 0.79, p = 0.009) and venous thromboembolism (OR: 0.72, p = 0.006). CONCLUSIONS Spleen-conserving surgeries may be considered for patients with penetrating trauma, age<65, hemodynamic stability, and low-grade injuries. Spleen-conserving surgeries have decreased risk of pneumonia and venous thromboembolism.

Abstract
BACKGROUND The authors aimed to use preoperative computed tomography images to develop a radiomic nomogram to select patients who would benefit from spleen-preserving splenic hilar (No.10) lymphadenectomy (SPSHL). METHODS A pooled analysis of three distinct prospective studies was performed. The splenic hilar lymph node (SHLN) ratio (sLNR) was established as the quotient of the number of metastatic SHLN to the total number of SHLN. Radiomic features reflecting the phenotypes of the primary tumor (RS1) and SHLN region (RS2) were extracted and used as predictive factors for sLNR. RESULTS This study included 733 patients: 301 in the D2 group and 432 in the D2+No.10 group. The optimal sLNR cutoff value was set at 0.4, and the D2+No.10 group was divided into three groups: sLNR=0, sLNR ≤0.4, and sLNR >0.4. Patients in the D2+No. 10 group were randomly divided into the training ( n =302) and validation ( n =130) cohorts. The AUCs value of the nomogram, including RS1 and RS2, were 0.952 in the training cohort and 0.888 in the validation cohort. The entire cohort was divided into three groups based on the nomogram scores: low, moderate, and high SHLN metastasis burden groups (LMB, MMB, and HMB, respectively). A similar 5-year OS rate was found between the D2 and D2+No. 10 groups in the LMB and HMB groups. In the MMB group, the 5-year OS of the D2+No. 10 group (73.4%) was significantly higher than that of the D2 group (37.6%) ( P <0.001). CONCLUSIONS The nomogram showed good predictive ability for distinguishing patients with various SHLN metastasis burdens. It can accurately identify patients who would benefit from SPSHL.

Abstract
Importance Splenic hilar lymphadenectomy has been recommended for locally advanced proximal gastric cancer (APGC) involving the greater curvature. However, it is unclear whether laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPSHL) is associated with a long-term survival benefit for APGC without greater curvature invasion. Objective To present the 5-year follow-up data from a randomized clinical trial that compared laparoscopic total gastrectomy (D2 group) with D2 plus LSPSHL (D2 + No. 10 group) among patients with resectable APGC. Design, Setting, and Participants This is a post hoc secondary analysis of a randomized clinical trial that enrolled 536 patients with potentially resectable APGC (cT2-4a, N0 or N+, and M0) without greater curvature invasion from January 5, 2015, to October 10, 2018. All patients were tracked for at least 5 years. The final follow-up was on October 30, 2023. Interventions Patients were randomly assigned in a 1:1 ratio to the D2 + No. 10 or D2 groups. Main Outcomes and Measures The 5-year disease-free survival (DFS) and overall survival (OS) rates were measured. Recurrence patterns and causes of death were compared. Results A total of 526 patients (392 men [74.5%]; mean [SD] age, 60.6 [9.6] years) were included in the modified intent-to-treat analysis, with 263 patients in each group. The 5-year DFS rate was 63.9% (95% CI, 58.1%-69.7%) for the D2 + No. 10 group and 55.1% (95% CI, 49.1%-61.1%) for the D2 group (log-rank P = .04). A statistically significant difference was observed in the 5-year OS between the D2 + No. 10 group and the D2 group (66.2% [95% CI, 60.4%-71.9%] vs 57.4% [95% CI, 51.4%-63.4%]; log-rank P = .03). The No. 10 lymph node exhibited a therapeutic value index (TVI) of 6.5, surpassing that of Nos. 8a (TVI, 3.0), 11 (TVI, 5.8), and 12a (TVI, 0.8). A total of 86 patients in the D2 + No. 10 group (cumulative incidence, 32.7%) and 111 patients in the D2 group (cumulative incidence, 42.2%) experienced recurrence (hazard ratio, 0.72; 95% CI, 0.54-0.95; P = .02). The multivariable competing risk regression model demonstrated that D2 + No. 10 remained an independent protective factor for a lower 5-year cumulative recurrence rate after surgery (hazard ratio, 0.75; 95% CI, 0.56-1.00; P = .05). There was a significant difference in the 5-year cumulative recurrence rate at the No. 10 lymph node area between the 2 groups (D2 + No. 10 group vs D2 group: 0% vs 2.3% [n = 6]; P = .01). Conclusions This post hoc secondary analysis of a randomized clinical trial found that laparoscopic total gastrectomy with LSPSHL can improve the prognosis and reduce recurrence for APGC without greater curvature invasion. Future multicenter studies are warranted to validate these findings. Trial Registration ClinicalTrials.gov Identifier: NCT02333721.

Abstract
Background: multiple studies showed important benefices arising from splenic preservation in patients with digestive cancer in general and gastric cancer in particular. The minimally invasive approach remains controversial in locally advanced gastric cancer cases whilst the open approach still has an important role. This paper's aim is to describe and present the feasibility of an open surgical technique that allows removing stations 10 together with 11p and 11d with spleen and splenic vessels preservation in pacients operated upon by open surgery. Material and Methods: We present an open "Ex-situ" spleen and pancreas preserving surgical technique that removes the anterior and posterior ganglia from the splenic hilum, the splenic vessels and the distal pancreas in locally advanced gastric cancer cases of the upper two thirds of the stomach. Forty-three consecutive patients since 2003 were operated upon by the author in multiple centers. during upper two thirds gastric cancer resections requiring no. 10 lymphadenectomy. Results: no splenectomy was needed . All the spleens were viable at postoperative Doppler echography and CT scans. No spleen migrated nor caused mechanical complications. No clinically significant pancreatic leaks were noticed. Two patients died during hospital stay, one of miocardial infarction and one of massive stroke. Pertinent follow up data and survival were not available. Conclusions: The method enables the surgeon to remove the lymph nodes no. 10 along with 11p and 11d without needing to sacrifice the spleen. All spleens were reattached sucessfully using the preserved spleno-renal ligament fold, no wandering spleen was noticed.

[PMID: 38418296 DOI: 10.1016/j.surg.2024.01.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/12/2023] [Accepted: 01/02/2024] [Indexed: 03/01/2024]
Abstract
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.

Abstract
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.

Abstract
BACKGROUND There is an ongoing debate regarding the comparative merits of splenectomy (SP) and splenic preservation in the surgical management of gastric cancer. This systematic review and meta-analysis aims to shed light on potential differences in survival outcomes and postoperative complications associated with these two procedures. METHOD An exhaustive literature search was conducted across multiple databases, namely PubMed, Embase, Cochrane Library, and Web of Science. We utilized a random-effects model via RevMan 5.4 software to conduct a meta-analysis of the hazard ratios (HRs) and risk ratios (RRs) associated with SP and spleen preservation. Subgroup analyses were based on various attributes of the included studies. We employed funnel plots to assess publication bias, and sensitivity analysis was conducted to gauge the stability of the combined results. Both funnel plots and sensitivity analysis were performed using Stata 12. RESULT Our research incorporated 23 observational studies and three randomized controlled trials, involving a total of 6,255 patients. SP did not yield superior survival outcomes in comparison to splenic preservation, a conclusion that aligns with the combined results of the randomized controlled trials. No statistically significant difference in survival prognosis was observed between SP and splenic preservation, irrespective of whether the patients had proximal gastric cancer or proximal gastric cancer invading the stomach's greater curvature. SP exhibited a higher incidence of all postoperative complications, notably pancreatic fistula and intraabdominal abscesses. However, it did not significantly differ from splenic preservation in terms of anastomotic leakage, incision infection, intestinal obstruction, intra-abdominal bleeding, and pulmonary infection. No significant difference in postoperative mortality between SP and splenic preservation was found. Funnel plots suggested no notable publication bias, and sensitivity analysis affirmed the stability of the combined outcomes. CONCLUSION Despite the lack of significant differences in certain individual complications and postoperative mortality, the broader pattern of our data suggests that SP is associated with a greater overall frequency of postoperative complications, without providing additional survival benefits compared to splenic preservation. Thus, the routine implementation of SP is not advocated.

Abstract
Hydatidosis is a zoonosis due to the development of the larval form of Echinococcus granulosus in humans. This disease is very frequent in many countries of North Africa such as Morocco. The most frequent locations of hydatid cysts are the liver (75%) and the lungs (15.4%). Splenic hydatid cyst occurs in only 5.1% of cases. The diagnosis remains challenging and is made upon a hundle of clinical, radiological, biological, and histological arguments. In this paper, we report a case of spleen-preserving surgery for a splenic hydatid cyst to suggest the best management of these hydatid cysts and avoid recurrences.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.
