Splenic infarction without thrombosis secondary to severe acute pancreatitis

Abstract Introduction: Acute pancreatitis is a common disease that is usually mild, although in some cases it may present complications, among which are vascular ones such as splenic infarction. Clinical case: A 71 years old woman was admitted for acute pancreatitis, who presented a torpid evolution throughout the first admission with associated acute cholecystitis and an encapsulated necrotic collection that required endoscopic drainage using a luminal apposition prosthesis and endoscopic necrosectomy. A month and a half later, the patient was readmitted for abdominal pain, with abdominal CT scan showing a very thinned splenic vein and patent artery without identifying thrombosis (with 700,000 platelets/mm3), associated splenic infarction as well as worsening of the inflammation of pancreatitis. Given these findings, we were decided to start anticoagulation with enoxaparin at prophylactic doses for splenic vascular stenosis, achieving resolution of the thrombocytosis (410,000 platelets/mm3), disappearance of the splenic necrotic area and improvement of the pancreatic inflammatory component confirmed by CT scan. Conclusion: When splenic infarction is associated with severe pancreatitis with splenic thrombosis, anticoagulation is indicated. However, when there is no splenic thrombosis and the splenic infarction occurs in the context of critical vascular stenosis with high thrombocytosis, the indication for anticoagulation is controversial, with no consensus in the literature. Furthermore, at present it is not establish the active ingredient to be used or its dose, and highlights the need to carry out clinical trials in order to establish clinical or consensus guidelines.

A Case Report of Adenoviral Pneumonia with Splenic Infarction

Case Report: Hypercalcemia and Acute Kidney Injury Associated with Disseminated Paracoccidioidomycosis

Paracoccidioidomycosis is an acute to chronic systemic mycosis caused by the fungi Paracoccidioides. Hypercalcemia is a rare and not fully understood presentation of this infection. We present a case report of paracoccidioidomycosis associated with hypercalcemia and acute kidney injury (AKI) in an immunocompetent patient. An immunocompetent 30-year-old man from Brazil presented with papular erythematous-violaceous skin lesions, disseminated lymphadenopathy, pain in the left hypochondrium, fever with night sweats, and loss of 25 kilograms in 5 months. The result of a biopsy of the lesions was positive for Paracoccidioides brasiliensis. Laboratory findings were high total calcium and 1,25-dihydroxy vitamin D, with low parathyroid hormone, low albumin, and AKI. Computed tomography scans revealed splenic infarcts without bone lesions. Treatment was performed with methylprednisolone and liposomal amphotericin B. Calcium levels and kidney function normalized within 20 days of hospitalization. The patient was discharged 49 days after admission. A follow-up 6 months later revealed total clinical and serological remission.

A case of severe psittacosis pneumonia complicated by splenic infarction

Clinical dataChlamydia psittaci pneumonia is a community-acquired pneumonia caused by Chlamydia psittaci. While severe cases may lead to critical conditions such as respiratory failure, splenic infarction is relatively uncommon. A severe patient with Chlamydia psittaci pneumonia admitted to our hospital experienced a splenic infarction during treatment. Fortunately, the patient’s situation was improved after careful treatment. Now, the patient has been discharged. Further exploration of the mechanism of concurrent splenic infarction is required.BackgroudPsittacosis pneumonia, a zoonotic infectious disease transmitted from birds to humans, is caused by Chlamydia psittaci and represents a type of chlamydial pneumonia [1]. Insome instances, the disease may progress to severe pneumonia and respiratory failure, necessitating intensive support measures, including mechanical ventilation. The advent of technologies such as Metagenomic Next-Generation Sequencing (mNGS) for the etiological diagnosis of infectious diseases [2] has improved the diagnostic and treatment success rates for Psittacosis. Instances of severe chlamydial pneumonia with complications such as splenic infarction are uncommon. A patient with severe Psittacosis pneumonia complicated by splenic infarction was admitted to the Emergency Intensive Care Unit (EICU) of Haining People’s Hospital and subsequently improved following effective anti-infective and anticoagulant therapy. This report is provided herein.

Superiority of Robotic Over Laparoscopic Spleen-Preserving Distal Pancreatectomy With Warshaw Procedure for Reducing the Incidence of Postoperative Splenic Infarction.

Minimally invasive spleen-preserving distal pancreatectomy with Warshaw procedure (MI-WP), has gained widespread recognition for the treatment of benign and low-grade malignant tumors of the pancreatic body and tail. However, the comparative advantages of the robotic Warshaw procedure (R-WP) over the laparoscopic Warshaw procedure (L-WP) remain uncertain. This study aimed to compare the surgical outcomes between R-WP and L-WP. Among the 146 cases of MI-DP conducted between October 2020 and December 2023 (L-DP:115, R-DP:31), 33 cases of MI-WP were subjected to analysis, comprising the R-WP group (n=10) and the L-WP group (n=23). R-WP successfully completed all procedures under a purely laparoscopic approach, whereas L-WP necessitated conversion to open surgery in 2 cases (8.7%). Despite the significantly prolonged operative time in R-WP compared with L-WP (R-WP vs. L-WP: 421vs. 300 min), there was no significant difference in estimated blood loss between the 2 groups (R-WP vs. L-WP: 19 vs. 20mL). Although the rate of major complications did not significantly differ between the 2 groups, 2 cases (8.7%) of L-WP required reoperation, including splenectomy in 1 instance. Furthermore, the incidence of postoperative splenic infarction was significantly higher in L-WP than in R-WP (R- vs. L-WP:0 vs. 43.5%, P =0.015). The length of hospital stay after surgery did not exhibit a significant difference between the 2 groups (R-WP vs. L-WP: 11 vs. 12d). R-WP demonstrated superiority to L-WP for reducing the incidence of postoperative splenic infarction, potentially contributing to enhancing the spleen preservation rate.

From flank pain to splenic abscess: a complex case of infective endocarditis with literature review

BackgroundInfective endocarditis (IE) is a severe condition characterized by inflammation of the heart endocardium and valves, commonly caused by Gram-positive bacteria. Complications such as embolic phenomena and organ abscesses can arise, necessitating timely diagnosis and intervention.Case presentationWe report the case of a 20-year-old female with a history of cerebral and splenic infarctions due to IE. The patient presented with left-sided flank pain, urinary burning, and fever. Examination revealed mitral and aortic valve involvement, splenomegaly, and neurological deficits. Despite initial antibiotic therapy, the patient developed a splenic abscess and drug-induced neutropenia. She required aortic valve replacement and was successfully managed with a multidisciplinary approach.ConclusionMultidisciplinary management, including timely surgical intervention and advanced imaging, is essential for favorable outcomes in IE patients. This case underscores the importance of early detection and tailored treatment strategies in managing severe complications associated with IE.

Change of skeletal muscle mass in cirrhotic patients with hypersplenism after partial splenic artery embolization

PurposePartial splenic artery embolization (PSAE) is an effective procedure for cirrhotic patients with hypersplenism. The aim of our study is to evaluate the effect of PSAE on skeletal muscle, and to identify the predictor for an improvement in skeletal muscle index (SMI) in cirrhotic patients with hypersplenism after PSAE. Materials and Methods466 cirrhotic patients with hypersplenism underwent PASE between Dec 2013 and Mar 2022. Medical records and CT images of enrolled patients were analyzed. Results105 cirrhotic patients with hypersplenism were enrolled. Sarcopenia was observed in 60.00 % (63/105) of these patients, 68.25 % (43/63) of male patients, and 31.75 % (20/63) of female patients. In cirrhotic patients, no significant change in the mean SMI at the third lumbar vertebra (L3) level after PSAE. In patients with sarcopenia, the L3 SMI increased from 36.77 cm2/m2 (baseline) to 43.38 cm2/m2 (P < 0.01), the L3 subcutaneous fat area (SFA) increased from 79.16 cm2 (baseline) to 103.52 cm2 (P < 0.01) at 12-month follow-up after PSAE. In patients without sarcopenia, the L3 SMI decreased from 58.38 cm2/m2 (baseline) to 49.44 cm2/m2 (P < 0.05), the L3 SFA increased from 89.63 cm2 (baseline) to 94.77 cm2 (P > 0.05) at 12-month follow-up after PSAE. Univariate and multivariate analysis demonstrated splenic infarction rate (OR: 0.01, P = 0.0032) and SMI (OR: 0.84, P < 0.001) were independent predictors for an improvement in skeletal muscle in patients with sarcopenia. ConclusionsIn cirrhotic patients with sarcopenia, an improvement in skeletal muscle and fat mass was observed after PSAE; splenic infarction rate and the L3 SMI before PSAE predicted an improvement in skeletal muscle index in patients with sarcopenia after PSAE.

Ten-year experience of laparoscopic partial splenectomy for patients with splenic benign lesions

BackgroundThe increasing comprehension of spleen function has led to the gradual endorsement of laparoscopic partial splenectomy (LPS) as a treatment option for benign spleen lesions. However, it is important to note that the LPS technique remains challenging. This study explores the standardized process and surgical techniques in LPS, aiming to promote the application of this technique. MethodsThe clinical data of 20 patients with benign cystic or solid spleen lesions who underwent LPS at Shunde Hospital, Southern Medical University were retrospectively collected. Data include age, gender, imaging data, surgical process, and postoperative complications. Additionally, the surgical techniques and standardization process were recorded in detail. ResultsAll 20 cases completed LPS without conversion to laparotomy or splenectomy. The surgical time was 162.25 ± 37.96 min, the intraoperative blood loss was 93.00 ± 58.40 mL, no blood products were transfused during the operations, and the removed volume of the spleen was about 34.75 ± 12.19 %. There were no postoperative complications such as intra-abdominal bleeding, intra-abdominal infection, pancreatic fistula, and residual splenic infarction. Postoperative pleural effusion occurred in four cases, and symptoms improved after symptomatic treatment. The postoperative hospital stay was 7.0 ± 1.4 days. There were no perioperative deaths. The residual splenic vessels were normal during the follow-up period, and no vascular embolism occurred. ConclusionsLPS is a safe, feasible, and effective surgical method for patients with benign cystic or solid spleen lesions. Subsequently, mastering related surgical techniques and standardized surgical procedures can control the surgical risks in suitable cases, making LPS the standard procedure for treating benign spleen diseases.

Cystic splenic lesions: a sonographic approach-retrospective study in 111 patients.

To describe and categorize splenic cystic-appearing lesions (S-CAL) with B-mode and contrast-enhanced ultrasound (CEUS). This retrospective study investigated S-CALs in 111 patients between 2003 and 2023 in an interdisciplinary ultrasound center with B-mode ultrasound, color Doppler sonography (CDS), and CEUS. S-CAL was characterized by echogenicity, diameter, and shape, as well as additional features like septation, calcification, or wall thickening, and CDS/CEUS were used to identify perfusion. Histological examination or imaging follow-up was necessary to determine the nature of S-CAL. Moreover, 'S-CAL with risk' was defined, necessitating further procedures. Four types (0-III) of S-CALs were defined based on ultrasound parameters. Fisher's exact test was used to compare non-parametric data. S-CAL of 111 patients (58 female, 53 men-average age: 58.6 years) was examined. Final diagnoses were: splenic cyst (n = 64, 57.7%); splenic abscess (n = 10, 9.0%); intrasplenic pseudoaneurysm (n = 10, 9.0%); splenic metastasis (n = 10, 9.0%); splenic infarction (n = 6, 5.4%); splenic hematoma (n = 4, 3.6%); other (n = 7, 6.3%). S-CAL groupings were type 0 (n = 11, 9.9%), type I (n = 33, 29.7%), type II (n = 24, 21.6%), and type III (n = 43, 38.7%). 'S-CAL with risk' was diagnosed in n = 41 (36.9%). Malignant S-CAL was only seen in type II (n = 2, 8.2%) and type III (n = 9, 20.9%) (p < 0.001). 'S-CALs with risk' were found more frequently in type 0 (n = 11, 100%), type II (n = 16, 66.7%) and type III (n = 13, 30.2%) than in type I (n = 1, 3%) (p < 0.001). B-mode ultrasound, CDS, and CEUS are useful to further characterize and follow-up S-CAL and identify 'S-CAL with risk', requiring further procedures. Ultrasound imaging is valuable for the detection, categorization, and monitoring of cystic-appearing lesions of the spleen, as well as for the identification of those with risk. An S-CAL may introduce uncertainty in clinical practice as imaging-based risk stratification is missing. B-mode and CEUS, along with the clinical context and follow-up, assist in characterizing and identifying 'S-CAL with risk'. S-CALs encompass various lesions, including simple cysts, metastases, abscesses, and intrasplenic pseudoaneurysms.

Splenic infarction in patients with Epstein-Barr virus infectious mononucleosis-case reports and literature review

Introduction: Epstein-Barr virus (EBV) is one of the most common herpes viruses in humans with over 90% of adults demonstrating antibodies to EBV. Infectious mononucleosis (IM) is the most frequently occurring clinical presentation of EBV infection and typically presents with fever, tonsillitis/pharyngitis, cervical lymph node enlargement and tenderness and fatigue. Splenomegaly is also part of the clinical presentation. Splenic infarction (SI) due to IM is rare but its exact frequency is unknown. Methods: We present two cases of SI accompanying IM caused by EBV in young adults without underlying comorbidities together with a literature review of this topic. Literature search included journal articles describing splenic infarctions confirmed by CT or MRI associated with IM due to EBV infection published in English between 2005 and 2024 in PubMed. A total of 32 case reports presenting 34 patients were selected for detailed analysis. Results: Among 34 patients, 58,8% were males and the median age was 20.97 years. Only 26.5% of patients had some chronic disease, the most common one being hereditary spherocytosis present in four patients. The most common symptoms were: fever (82.4%), abdominal pain (88.2%) localized mostly in the left upper abdomen and splenomegaly (50%). Conclusion: Our overall conclusion is that establishing the diagnosis of SI does not change the therapeutic approach in most cases and that symptomatic treatment is sufficient. In the future, greater availability of abdominal imagining methods and a higher index of suspicion will lead to more accurate data about SI.

Acute splenic pathology on CT in patients with babesiosis.

To better understand the occurrence of splenic disease as a potential manifestation of babesiosis by retrospectively estimating the frequency of acute splenic injury on abdominal and pelvic CT in a cohort of patients with active babesia infection. In a search of our single institution, suburban teaching community hospital database, 57 patients were found to have positive babesia infection between the years 2021-2023. 29 of these patients underwent abdominal and pelvic CT (22 with and 7 without intravenous contrast), and 3 underwent abdominal ultrasound without any CT. The imaging was reviewed for the presence or absence of splenic abnormalities, and for follow-up imaging. Parasitemia levels at the time of imaging were also reviewed; parasitemia levels < 4% are associated with mild to moderate disease, whereas parasitemia levels > 4% are associated with severe disease. 21/32 (66%) patients who underwent any type of abdominal imaging (ultrasound, MRI, and CT) had splenomegaly. Of the 22 patients who had IV contrast-enhanced CT scans, 6 were found to have splenic infarction (27%). One of these 22 patients had multiple rounded non-peripheral hypoenhancing foci on both CT and MRI which did not meet criteria for infarction, in association with splenomegaly, and which resolved after treatment. 0/6 patients in the splenic infarction group had parasitemia levels greater than 4%, while 4 of the 16 patients (4/16) without infarction had parasitemia levels of greater than 4%. Our study showed that splenic disease in patients with babesiosis mostly took the form of splenomegaly, and in a substantial minority of patients as splenic infarction. There were no cases of splenic rupture and perisplenic hematoma in our case series, likely reflecting a limitation of the relatively small study size. Concordant with prior studies, we found no identifiable association between parasitemia levels and the presence of splenic infarction.

Abstract We065: Sex Differences in Autoimmune Signatures After Myocardial Infarction in Mice

Introduction: Myocardial infarction (MI) is caused by ischemic injury to the left ventricle (LV), leading to an inflammatory response, scar formation, and loss of LV function. The role of the autoimmune (AI) response during chronic MI, such as B cell activation and autoantibody production, is not well understood. As AI disease is much more prevalent in females, we hypothesized that female mice are more susceptible to MI-induced development of AI signatures. Methods: Permanent MI was induced by left coronary artery ligation in adult male and female C57BL/6J mice for 7, 28, or 56 days. LV function was tracked using echocardiography (VEVO 3100). Cytokines were measured by qPCR. LV IgG and IgM antibody deposition was measured by immunofluorescence. Plasma IgG and IgM were measured by ELISA, and plasma autoantibodies (AABs) (IgG and IgM subclasses) were measured with an autoantigen (AAN) array. Results: In both sexes, MI led to progressive LV hypertrophy, dilation, and wall thinning. MI increased spleen mass in D7, 28, and 56 females, but decreased spleen mass in D28 and 56 males. LV infarct cytokines (IL-1β, IL-6, IL-18, IFN-γ, TNF, CCL2, IL-10) were increased at D7, while IL-6 and IL-18 remained elevated at D28 and 56 to a higher degree in females. Several cytokines in the remote LV were increased in females relative to males, including TNF, IL-6, CCL2, and IL-18. Splenic cytokines were also differentially expressed between sexes, with IL-1β, IL-12a, IL-10, IFN-γ, IL-18, CCL2, and IL-4 increased in females at several time points. Infarct IgG and IgM deposition occurred in both sexes, but to a higher degree in females. Remote IgG and IgM deposition occurred at D56 in both sexes. For plasma AABs, we detected 34 AANs against which IgG AABs were significantly elevated (p&lt;0.05) at D56 in females vs 9 in males, and 30 IgM AABs vs 1 in males. Of note, anti-IL-6 IgM AABs were elevated in D56 females (9.8±0.8-fold), likely due to persistently elevated IL-6 in the female infarct and remote LV vs males. Total levels of plasma IgM were increased only in females at D56 (1.79±0.15-fold). Conclusions: MI promotes development of AI signatures which is exacerbated in females, including increased spleen mass, LV and splenic cytokines, LV infarct and remote IgG and IgM antibody deposition, increased plasma IgG and IgM AABs, and increased total levels of plasma IgM. Targeting the AI response may be a viable option for treating chronic MI outcomes, particularly in females.

Unveiling the devastations of streptococcus sanguinis infective endocarditis masquerading as iron deficiency anaemia: a case report

Abstract Background Iron deficiency is the leading cause of anaemia worldwide and frequently observed in adolescent women, particularly those with eating disorders like anorexia nervosa. Consequently, clinicians may overlook iron deficiency anaemia, potentially missing a more serious diagnosis. Case summary A 19-year-old woman was referred to the hospital by her general practitioner due to worsening symptomatic iron deficiency anaemia, despite treatment with oral iron supplementation. Her blood cultures consistently grew Streptococcus sanguinis, and an echocardiogram revealed vegetations on the mitral and tricuspid valves, confirming the diagnosis of infective endocarditis. Several systemic complications of varying acuity were identified, including a ruptured left common iliac artery aneurysm with active haemorrhage into the left psoas muscle, enlarging cerebral, hepatic, and right common femoral artery aneurysms, splenic infarction with abscess formation, and an infected left psoas muscle hematoma. Multimodal imaging and collaboration within the multidisciplinary endocarditis team were crucial for coordinating further evaluation and managing the complex array of peripheral lesions in infective endocarditis. The patient was discharged with a good clinical outcome after 81 days. Discussions This case highlights the risks of overlooking iron deficiency anaemia in adolescent women with anorexia nervosa and the serious consequences of untreated complicated infective endocarditis. It emphasises the need for thorough investigation of anorexia nervosa patients for infections due to their reduced clinical response, to ensure early diagnosis and treatment.

Epidemiology, outcomes and prognosis of infective endocarditis in Northern Morocco

IntroductionInfective endocarditis is a rare but potentially severe disease, associated with significant morbidity and mortality. Our study aims to describe the epidemiology and management aspects of endocarditis in northern Morocco and compare it with international management guidelines.Materials and MethodsThis is a retrospective study involving all patients hospitalized in the cardiology department of the University Hospital of Tangier for infective endocarditis over a period of 4 years and 7 months, from May 2019 to February 2024.ResultsEighty patients were hospitalized for IE during the study period. The average age of the patients was 46 years, with an even sex ratio. IE concerned native valves in 77% of cases, mechanical prostheses in 19% of cases, and on bio prostheses in 4%. The average diagnostic delay was 25 days. Blood cultures were negative in 59% of cases. The predominant infective microorganism was the bacteria Staphylococcus (65.6%).Imaging results showed vegetations in 76.3% of cases, predominantly on the mitral valve (39.3%), followed by the aortic valve (21.3%). The main complications included heart failure (51.2%), peripheral arterial embolisms (22.5%) and splenic infarction (17.5%).Management wise, the most commonly used antibiotic therapy was a combination of ceftriaxone and gentamicin. Clinical and biological improvement was observed in 70% of cases, with a mortality rate of 12.5%. Twelve patients underwent surgery (15%). Urgent surgery was indicated in 66,7% of the operated patients.ConclusionOur study highlights the challenges in managing infective endocarditis in northern Morocco. The prognosis of infective endocarditis can be improved through multidisciplinary management within the implementation of an Endocarditis Team.

Splenic artery embolization in the treatment of blunt splenic injury: single level 1 trauma center experience.

To describe the experience of a single level 1 trauma center in the management of blunt splenic injuries (BSI). This is a retrospective study with Institutional Review Board approval. The medical records of 450 patients with BSI treated between January 2016 and December 2022 were reviewed. Seventy-two patients were treated with splenic artery embolization (SAE), met the study criteria, and were eligible for data analysis. Spleen injuries were graded in accordance with the American Association for the Surgery of Trauma Organ Injury Scale. Univariate data analysis was performed, with P < 0.05 considered statistically significant. The splenic salvage rate was 90.3% (n = 65/72). Baseline demographics were similar between the groups (P > 0.05). Distal embolization with Gelfoam® had similar rates of splenic salvage to proximal embolization with coils (90% vs. 94.1%, P > 0.05). There was no significant difference in the rate of splenic infarction between distal embolization with Gelfoam® (20%, 4/20) and proximal embolization with coils (17.6%, 3/17) (P > 0.05). There was no significant difference in procedure length (68 vs. 75.8 min) or splenic salvage rate (88.5% vs. 92.1%) between proximal and distal embolization (P > 0.05). There was no significant difference in procedure length (69.1 vs. 73.6 min) or splenic salvage rate (93.1% vs. 86.4%) between Gelfoam® and coil embolization (P > 0.05). Combined proximal and distal embolization was associated with a higher rate of splenic abscess formation (25%, 2/8) when compared with proximal (0%, 0/26) or distal (0%, 0/38) embolization alone (P = 0.0003). The rate of asymptomatic and symptomatic splenic infarction was significantly higher in patients embolized at combined proximal and distal locations (P = 0.04, P = 0.01). The endovascular management of BSI is safe and effective. The overall splenic salvage rate was 90.3%. Distal embolization with Gelfoam® was not associated with higher rates of splenic infarction when compared with proximal embolization with coils. Combined proximal and distal embolization was associated with a higher incidence of splenic infarction and splenic abscess formation. Distal splenic embolization with Gelfoam® is safe and may be beneficial in the setting of blunt splenic trauma.

Interim analysis of short-term outcomes after laparoscopic spleen-preserving distal pancreatectomy with or without preservation of splenic vessels: a randomised controlled trial.

Laparoscopic spleen-preserving distal pancreatectomy (LSPDP) is a widely adopted surgical approach for benign and low-grade malignant neoplasms of the distal pancreas. The Kimura and Warshaw techniques represent two principal strategies, yet it still needs to be determined which one is superior. Our investigation aimed to evaluate the clinical outcomes associated with each technique. This single-center, parallel-group, patient-blinded randomized controlled trial (RCT) was conducted at the XXXXX University. Stratified block randomization was utilized to enroll 114 patients starting in March 2022, with an interim analysis of short-term outcomes scheduled after 45%-50% of participant enrollment. Patients were randomized to receive LSPDP via either the Kimura or Warshaw technique. The primary endpoint was intraoperative blood loss, while secondary endpoints included a range of outcomes from composite outcome to quality of life, as quantified by the EQ-5D-5L. From March 2022 to November 2023, 53 patients were randomly allocated to the Kimura (n=25) or Warshaw (n=28) groups for LSPDP. Baseline characteristics and postoperative outcomes were similar between the groups, such as pancreatic fistula incidence, EQ-5D-5L index scores, and delayed gastric emptying rates. Per-protocol (PP) analysis revealed that the Kimura group experienced significantly less blood loss (52.5±51.6mL vs. 91.7±113.5mL, P=0.007) and a reduced rate of composite outcome (23.8% vs. 56.7%, P=0.019), but incurred higher costs in the Warshaw group (¥56,227.4±¥7,027.0 vs. ¥63,513.8±¥12,944.5, P=0.013). Splenic infarction rates were higher in the Warshaw group, though not statistically significant (ITT: 39.3% vs. 12.5%, P=0.058; PP: 36.7% vs. 14.3%, P=0.113), without necessitating intervention. Neither group experienced postpancreatectomy haemorrhage, 90-day mortality, or ICU admissions, and all postoperative complications were mild (Clavien-Dindo Grade <III). The 90-day interim analysis postoperatively indicates that both Kimura and Warshaw techniques for LSPDP are safe and viable. The Kimura technique, however, confers superior in terms of reduced intraoperative blood loss and fewer complications, alongside lower costs.
