Splenectomy

Splenectomy is a surgical procedure involving the removal of the spleen, an organ located in the upper left part of the abdomen.
The spleen plays a crucial role in the body's immune system and blood filtration.
Splenectomy may be performed as a treatment for various conditions, such as an enlarged or damaged spleen, certain blood disorders, or splenic injuries.
The procedure can be done through open surgery or minimally invasive techniques like laparoscopic splenectomy.
Patients undergoing splenectomy may require lifelong antibotic prophylaxis and monitoring to manage the increased risk of infection due to the absence of the spleen.
Reserarch into optimal splenectomy protocols and techniques is ongoing to improve outcomes and reduce complications for patients.

Over the 6‑month period covering April 2010 to September 2010, all patients admitted to one of our patient wards at the Division of General Surgery, Department of Surgery, Medical University of Vienna were included in this study.
The Division of General Surgery in our university hospital consists of the following teams and specializations: colorectal surgery, hepatobiliary surgery, endocrine surgery, upper gastrointestinal (GI) surgery (esophageal and stomach surgery), bariatric surgery, breast surgery, and pancreatic surgery.
The patient data were extracted by reviewing all discharge letters from that period taken from the digital archives.
Overall, 517 patients were admitted over this period, some repeatedly, leading to a total of 817 admissions. These 517 patients underwent 463 operations. The complications of these operations were then rated according to the Clavien-Dindo classification (Table 1). For easier use, the suffix “d” for permanent disability was not drawn upon.

Clavien-Dindo classification

GradeDefinition
Grade IAny deviation from the normal postoperative course without the need for pharmacological treatment, or surgical, endoscopic, and radiological interventions.Allowed therapeutic regimens are: drugs as antiemetics, antipyretics, analgetics, diuretics and electrolytes, and physiotherapy. This grade also includes wound infections opened at the bedside
Grade IIRequiring pharmacological treatment with drugs other than such allowed for grade I complications.Blood transfusions and total parenteral nutrition are also included
Grade IIIRequiring surgical, endoscopic, or radiological intervention
Grade IIIaIntervention not under general anesthesia
Grade IIIbIntervention under general anesthesia
Grade IVLife-threatening complication (including central nervous system complications) requiring IC/ICU management
Grade IVaSingle organ dysfunction (including dialysis)
Grade IVbMultiorgan dysfunction
Grade VDeath of a patient

According to Dindo et al. [6 (link)]

IC intermediate care, ICU intensive care unit

The operations were sorted according to the complexity ranking (eight groups) in the accounting system of the Austrian Chamber of Physicians (Table 2; [8 ]).

When possible, we excluded samples with any of the following: pregnancy (when complete blood count (CBC) done), acute medical/surgical illness (when CBC done), blood cancer, leukemia, lymphoma, chemotherapy, myelodysplastic syndrome, bone marrow transplant, congenital or hereditary anemia (e.g., hemoglobinopathy such as sickle cell anemia or thalassemia), HIV, end-stage kidney disease, dialysis, EPO treatment, splenectomy, cirrhosis and those with any of the following extreme measurements: WBC count > 100109/L with > 5% immature cell or blasts, WBC > 200109/L, Hemoglobin > 20 g/dL, Hematocrit > 60%, Platelet > 1000109/L. For the WBC subtypes (e.g., basophils count) we used the relative count, i.e., the total WBC count multiplied by the proportion for each cell type (e.g., basophils percentage). Raw phenotypes were regressed on age, age-squared, sex, principal components and cohort specific covariates (e.g., study center, cohort, etc) if needed, WBC related traits were log10 transformed before regression modeling. Residuals from the modeling were obtained and then inverse normalized for cohort level association analysis or GWAS. All cohorts followed the same exclusions and phenotype modeling except for UKBB and INTERVAL that had their procedure described elsewhere (Astle et al., 2016 (link)). The cohort level association analyses were then conducted using a linear mixed effects model in order to account for known or cryptic relatedness (e.g., BOLT-LMM (Loh et al., 2015 (link), 2018 (link)), EPACTS https://github.com/statgen/EPACTS and rvtests (Zhan et al., 2016 (link)) with the additive genetic model. Linear mixed effects models have been shown to effectively account for both population structure and inter-individual relatedness within the UK Biobank cohort, along with having increased discovery power over simple linear regression with principal components.

For the analysis of sensitivity, the mixed model analyses were replicated first excluding patients with pancreatic adenocarcinoma, then patients with a Clavien–Dindo complication score11 (link) of IIIa or higher, and lastly patients who had undergone a spleen-preserving procedure. Because of the results of the latter, separate mixed model analyses were done comparing patients who had undergone splenectomy with those who had not.

Patients with liver dysfunction were given liver protection treatment, vitamin supplementation, and anemia correction before surgery, especially for Child–Pugh class C, which should be adjusted to class B. Open splenectomy was used in all cases. The splenic colonic and gastric splenic ligaments were separated, and the splenic artery was fully exposed and ligated under unambiguous vision. Next, the second- and third-grade branch vessels of the spleen were dissected and ligated one by one. After that, the splenic ligament was dissociated sharply, and the spleen was completely removed. For patients with pericardia varices, the esophageal branches, lateral branches, and inferior diaphragmatic branches about 5 cm in the lower esophagus were ligated and severed. Finally, drainage tubes were placed, followed by layer and layer suture. Postoperative anti-infection, liver protection and other support treatments were given.

The included demographic features were age, sex, and Child–Pugh classification (scores of 5–6, 7–9, and 10–15 for classes A, B, and C, respectively). Method of surgery, whether anatomic splenectomy was performed, BMI at admission: BMI = weight (kg)/height (m2), diabetes mellitus, hypertension, smoking history (one or more cigarettes daily for 6 months), duration of surgery, intraoperative bleeding and splenomegaly grade. Patients fasted for 8–12 h, and 5 mL of venous blood was extracted at 8 am before the procedure. Automatic hemacytometer (XN-9000, Sysmex Corporation, Japan) was used to detect the level of WBC, RBC, hemoglobin (HGB), and hematocrit (HCT) by counter method. Activated partial thromboplastin time (APTT), prothrombin time (PT), and fibrinogen (FIG) were determined using the coagulation method, and D-dimer was determined using immunoturbidimetry. Automatic biochemical analyzer (7600-010, Hitachi, Ltd. Japan) was employed to detect the level of alanine transaminase (ALT), while aspartate transaminase (AST) was determined using the rate method. Albumin (ALB) concentration was measured using bromocresol green method, while total bilirubin (TBIL) was measured using the diazo method. Blood urea nitrogen (BUN) level was ascertained using HMMPS method, and serum creatinine (CER) was determined using the uric acid method. The dynamics of blood flow [portal vein diameter (PVD), splenic vein diameter (SVD), portal vein flow (PVF), and portal vein velocity PVV)] were determined using color Doppler ultrasound (ACUSON Antares, Siemens AG, Germany) with 5.0 MHz wide-screen concave array probe.
