Effects of perioperative steroid use on surgical stress and prognosis in patients undergoing hepatectomy: a systematic review and meta-analysis of randomized controlled trials.

The objective of this study was to evaluate the clinical effects of perioperative steroid hormone usage in hepatectomy patients through a comprehensive systematic review and meta-analysis. Prospective randomized controlled trials (RCTs) investigating the perioperative use of steroid hormones in hepatectomy patients were systematically searched using various databases, including PubMed, Medline, Embase, the Cochrane Library, the Chinese Biomedical Literature Database, Wanfang Data, and the CNKI database. Two researchers independently screened and extracted data from selected studies. Data analysis was performed using RevMan 5.3 software. The results revealed significantly lower levels of total bilirubin (standard mean difference [SMD] = -0.7; 95% CI: -1.23 to -0.18; and p = 0.009), interleukin-6 (SMD = -1.02; 95% CI: -1.27 to -0.77; and p < 0.001), and C-reactive protein (SMD = -0 .65; 95% CI: -1 .18 to -0.11; and p = 0.02) on postoperative day 1 (POD 1), as well as a reduced incidence of postoperative complications in the steroid group compared to the placebo group. No significant differences were observed between the two groups regarding alanine aminotransferase (ALT) levels, aspartic aminotransferase (AST) levels, or specific complications such as intra-abdominal infection (p = 0.72), wound infection (p = 0.1), pleural effusion (p = 0.43), bile leakage (p = 0.66), and liver failure (p = 0.16). The meta-analysis results indicate that perioperative steroid usage can effectively alleviate liver function impairment and inflammation response following hepatectomy while improving patient prognosis.

Insights Into Laparoscopic Port Site Complications: A Comprehensive Review.

Laparoscopic surgery has become a widely accepted standard of care for numerous procedures in the modern world. Nearly every major surgical procedure previously only possible by employing open techniques may now be completed laparoscopically, attributable to the quick advancement of technology and surgeons' abilities. There are several complications associated with the laparoscopic port site, either infective, non-infective, or neoplastic. This study aims to explore the morbidity associated with the port site following laparoscopic surgery and discuss the risk factors for complications. The umbilical port was most frequently associated with port-site hernia (PSH), followed by the epigastrium and the left and right hypochondrium. Prolonged port manipulation and reinsertion, longer surgical times, failure to effectively close the fascial defect, and wound infection are responsible for the development of PSH. Port-site infection (PSI) is one avoidable adverse effect of laparoscopic surgery. Patients who have a history of diabetes, malnourishment, prolonged preoperative hospital stays, preoperative Staphylococcus aureus colonization of the nares, perioperative blood transfusions, and tobacco or steroid use are more likely to have PSI. Port-site hydatid cyst (PSHC) and port-site tuberculosis (PST) are rare but possible. While uncommon, a doctor should rule out endometriosis if a painful mass in the surgical scar, such as the trocar site, is discovered in a reproductive-age woman who has had pelvic or obstetric surgery in the past. Port-site metastasis (PSM) is the term for tumor-cell implantation at the trocar insertion site after a malignant tumor is removed laparoscopically. PSM has been reported in 1-2% of laparoscopic gynecologic surgical procedures. A few potential mechanisms for cell implantation at the port site include embolization of exfoliated cells during tumor dissection or hematogenous spread, air turbulence during long laparoscopic operations, and direct implantation onto the wound during forced, unprotected organ/tissue retrieval or from contaminated surgical instruments during tumor dissection. Nonetheless, the triggering mechanism is likely essentially multifaceted.Prevention is better than cure. Port-site hernia can be prevented using smaller trocars and meticulous rectus sheath defect closure at the end of surgery. The rest of the port site complications can be prevented by employing autoclavable laparoscopic hand instruments, utilizing autoclaved water to clean the instruments following disassembly, adhering to the recommended concentration, contact duration, and usage cycles when sterilizing instruments with liquid sterilizers, preventing bile or gut content from spilling into the operating room or the port site, using non-porous specimen retrieval bags for recovering the specimen, and thoroughly cleaning and irrigating the port site before closing the wound.

491 Scalp Incisions With Stairstep Pericranial Edges to Minimize Sequalae of Poor Wound Healing in Supratentorial Brain Tumor Surgery

INTRODUCTION: Wound healing problems are especially prevalent in craniotomies for intra-axial brain tumors as patients often require radiation, chemotherapy, and chronic steroids. All surgeons have postoperative patients with poor skin healing (i.e., excessive scabbing) at follow up, some of whom progress to infections that may involve the bone graft or hardware. While newer techniques like minimally invasive approaches and routine vancomycin powder use have helped overall complication rates, poor skin healing remains a frustratingly persistent cause of morbidity. METHODS: Ninety-one consecutive patients underwent supratentorial, intra-axial brain tumor surgery with a single surgeon at a single institution using this technique. Patient demographics, pathology, adjuvant interventions, and other independent risk factors were analyzed. RESULTS: No wound-related complications requiring readmission, intravenous antibiotics, or reoperation were encountered at a median 3-month follow up. There were also no surgical site infections, dehiscences, or CSF leaks. Fifty-one patients (57.3%) had postoperative radiotherapy, eighty-five patients (93.4%) had perioperative steroids, and fifty-six patients (61.5%) had postoperative chemotherapy. Six patients (6.5%) had concerns for poor initial scalp healing at routine follow up and were placed on a short course of oral antibiotics prophylactically. None (0%) of these individuals progressed to infection or required further intervention. One other patient developed a shunt infection in this interval that required removal unrelated to the craniotomy site. CONCLUSIONS: Here we outline the principles and demonstrate the execution of stairstep pericranial edges in supratentorial brain surgery. This technique, designed with plastic surgeons, provides an intact, vascularized layer of pericranium beneath the incision and over the bone graft/hardware to optimize wound healing and prevent morbid sequelae in inevitable cases of poor initial skin healing.

Perioperative steroid injection in elbow arthroscopy.

The goal of the present study was to evaluate the incidence of infection after perioperative intra-articular steroid injection during elbow arthroscopy. Starting from May 2019, we prospectively included all patients that underwent an elbow arthroscopy for various indications. All patients received preoperative antibiotics intravenously and a corticosteroid injection immediately after portal closure. Patients who needed ligamentous repair and aged below 18 years old were excluded. Final follow up of all patients was 3 months. In total, 108 elbow arthroscopies were performed in 100 patients. No major complications and 1 minor complication were seen. One patient developed a seroma that resolved spontaneously after 14 days without intervention or antibiotics. In this patient group, a perioperative corticosteroid injection following elbow arthroscopy did not increase the chance of infection.

The Role of Steroids in the Preservation of Hearing and Vestibular Function in Cochlear Implantation.

Cochlear implant surgery is guided by principles of atraumatic insertion as to protect the inner ear. Previous studies suggest the potential benefit of steroids in patients undergoing cochlear implantation (CI), although the optimal route of administration has yet to be determined. We aim to systematically review the human studies of hearing and vestibular function preservation in patients undergoing CI receiving perioperative steroids and to discuss their role. Search performed in PubMed, EMBASE, and CENTRAL databases in December 2023. Studies comparing several methods of steroid delivery and conventional management for patients undergoing CI were identified. Primary outcomes included hearing and vestibular function preservation. Secondary outcomes included reported adverse events, routes of steroid administration, and the presence of a control group without steroid administration. A total of 15 studies (N = 659) met inclusion criteria. Methodology, doses, route of steroid administration, and follow-up duration differed between most studies. Audiometric, vestibular, and hearing preservation (HP) results were inconsistent. In 12 studies, perioperative steroids were associated with either increased HP or vestibular function preservation. Only two studies reported adverse events related to oral corticosteroid therapy. There is a tendency for perioperative steroids to have a positive impact, at least in the short term, on hearing and vestibular function preservation in CI. Topical corticosteroid therapy appears to have a superior risk-benefit profile. There is a need for future carefully designed randomized controlled trials to determine the ideal route of steroid administration and its real impact in the long term.

The Effects of Preoperative Epidural Steroid Injection on Pseudarthrosis Following Lumbar Fusion: A Retrospective Cohort Study.

Retrospective cohort study. The goal of this study is to evaluate the effects of preoperative lumbar epidural steroid injection on the rate of pseudarthrosis following lumbar spine fusion surgery. Epidural corticosteroids help to reduce nerve root edema and suppress proinflammatory cytokines in patients with radiculopathy. Corticosteroids may inhibit bone formation and reduce bone matrix synthesis rates. Thus, there is concern that corticosteroids may reduce lumbar fusion capability, potentially resulting in increased rates of symptomatic pseudarthrosis. We identified all patients who underwent 1-level or 2-level lumbar fusion surgery between 2018 and 2022. Patients were categorized into one of 3 groups: no preoperative epidural steroid injection (ESI) history (group 0), preoperative ESI within 90 days of surgery (group 1), or most recent ESI >90 days before surgery (group 2). The primary outcome of this study was pseudarthrosis. Binominal regression analyses were performed to determine the relationships between potential risk factors (sex, age, body mass index, smoking history, diabetes status, history of systemic steroid use, preoperative ESI, perioperative intravenous steroid administration, type of surgery, and postoperative ESI within 6mo) and the development of postoperative pseudarthrosis. A total of 446 patients were included in this study. Of those, 106 patients (23.7%) did not have a preoperative ESI (group 0), 132 patients (29.5%) had an ESI within 90 days of surgery (group 1), and 208 patients (46.6%) had their most recent ESI >90 days before surgery (group 2). The overall incidence of pseudarthrosis following lumbar fusion was 8.7% (39 of 446). Although the incidence of pseudarthrosis following ESI at any time point was higher than in our control cohort (group 0), this difference was not statistically significant. This study found no increased risk of postoperative pseudarthrosis in patients who underwent 1-level or 2-level lumbar fusions after preoperative ESI. Level III.

Role of procalcitonin, interleukin-6 and interleukin-10 as a predictive marker for the use of perioperative steroid in maxillofacial trauma patients

Maxillofacial trauma often brings significant challenges for surgeons in terms of preoperative oedema. Steroids offer oedema reduction, yet potentially increase the risks of postoperative infection. This study explores procalcitonin (PCT), as a marker for bacterial infection risk, and interleukins IL-6 and IL-10, which respectively signify pro-inflammatory and anti-inflammatory responses, as potential indicators of infection and inflammation in these trauma cases and thereby aid in refining perioperative guidelines for the use of steroids. A prospective study was conducted at a tertiary public hospital in India from 2019 to 2022 on patients >18 years with facial trauma. After specific exclusions, patients were randomised into steroid (Group A) and non-steroid (Group B) groups. Various parameters including oedema, PCT, IL-6, and IL-10 levels were measured and analysed using SPSS software. Out of 80 patients, 44 were in Group A and 36 in Group B. Post-24 hours, Group A showed significant oedema reduction, with 25 patients displaying a decline to mild oedema, versus 10 patients in Group B (p = 0.034). However, Group A witnessed a higher infection risk, with 20 patients showing positive wound cultures versus three in Group B. Subgroup analysis revealed a link between higher PCT levels and infections (p = 0.039). Additionally, Group A showed less intraoperative bleeding and reduced operating time. While perioperative steroids mitigate swelling, they might increase postoperative infection risk. Elevated PCT levels indicate potential wound infections, suggesting those patients should avoid perioperative steroids. IL-6 and IL-10 trends during perioperative phases can predict pronounced oedema outcomes.

Variability in Perioperative Steroid Therapy Regimen for Cochlear Implantation as It Relates to Hearing Preservation

Hypothesis We aimed to identify practice trends and association between physician training and administration of perioperative steroids for cochlear implantation (CI) as it relates to hearing preservation. Background Perioperative steroid therapy regimens are postulated to protect residual hearing and improve hearing preservation outcomes in CI. Methods A 27-question online survey was developed by the senior authors using the Qualtrics Survey Tool, then distributed via email from September to November 2022 to otolaryngologists specializing in otology or neurotology and who practice in the United States or Canada. Results The survey was sent to 463 physicians, 162 (35.0%) of whom completed the survey. One hundred forty-four (31.1%) responses underwent analysis. All physicians administering preoperative steroids (n = 31) prefer preoperative oral prednisone. Of 143 physicians administering intraoperative steroids, 54.5% prefer intraoperative intravenous dexamethasone. More than half (77.6%) of 85 physicians administering postoperative steroids prefer postoperative oral prednisone. Postoperative steroid administration (p &lt; 0.006) and taper utilization (p &lt; 0.041) were greater among physicians who complete greater than 40 CIs annually (n = 47 [71.2%]; n = 30 [49.2%]) than physicians who complete up to 40 CIs annually (n = 37 [48.7%]; n = 20 [31.3%]), respectively. Physicians practicing for 5 to 20 years after residency are more prevalent in using postoperative steroid tapers than physicians practicing for fewer than 5 years after and more than 20 years after residency (n = 37 [51.4%] versus n = 14 [25.5%], p &lt; 0.001). Conclusion Consensus is needed about the optimal steroid treatment for CI patients. Level of Evidence 4.

Laparoscopic Cholecystectomy in Pregnancy: A Seven-Year Retrospective Study From an Australian Tertiary Center.

Background Cholecystectomy is the second most common non-obstetric indication for surgery during pregnancy; however, there is little recent literature specifically exploring perioperative care approaches, and a paucity of Australian data exists. This study investigates the incidence of laparoscopic cholecystectomy (LC) during pregnancy, peri-operative management, and post-operative outcomes in a single Australian tertiary center. Methods A retrospective analysis of LCs performed on pregnant patients between the ages of 16 and 50 years at a tertiary hospital between 2016 and 2023 was completed. Results Twenty-three patients underwent LC. The median gestational age was 17+4weeks (4+3-30+6). Cases were performed in all three trimesters, with the majority in the second trimester (n=12, 52.2%). Surgery indications were recurrent biliary colic (n=11, 47.8%), acute cholecystitis (n=8, 34.8%), and gallstone pancreatitis (n=4, 17.4%). Obstetrics and Gynecology (O&G) consultations occurred in 56.5% (n=13) of cases. Fetal heart rate (FHR) was recorded perioperatively in 82.6% (n=19) of cases. Preoperative steroids were given to 40% of eligible patients. An intraoperative cholangiogram was performed in 12 (52.2%) cases, of which eight (66.7%) utilized abdominal shielding. There was no perioperative maternal mortality nor fetal loss. Surgical morbidities were pancreatitis (n=1), bile leak (n=1), and intraoperatively recognized bile duct injury (n=1). Two threatened preterm labors and five (26.3%) preterm deliveries occurred. Conclusion Performing LC in pregnancy does carry a risk of major morbidity; however, there was no mortality or fetal loss across all trimesters. The decision to perform abdominal shielding during an intraoperative cholangiogram should be approached sensitively in a case-by-case manner, given recent paradigm shifts in radiology. A multidisciplinary approach with standardized local perioperative care policies regarding procedures such as O&G consultation, perioperative steroid use, and FHR monitoring is strongly recommended.

Scalp Incisions With Stairstep Pericranial Edges to Minimize Sequalae from Poor Wound Healing in Supratentorial Brain Tumor Surgery: A Technical Note With Early Results

BACKGROUND AND OBJECTIVES: Wound healing problems are especially prevalent in craniotomies for intra-axial brain tumors as patients often require radiation, chemotherapy, and chronic steroids. Although newer techniques such as minimally invasive approaches and routine vancomycin powder use have helped overall complication rates, poor skin healing remains a frustratingly persistent cause of morbidity. Therefore, here we describe the novel technique of elevating and closing a stairstep pericranial edge offset from the skin incision to protect hardware and support wound healing, and we report early outcomes using this technique. METHODS: Ninety-one consecutive patients underwent supratentorial, intra-axial brain tumor surgery with a single surgeon at a single institution using this technique. Patient demographics, pathology, adjuvant interventions, and other independent risk factors were analyzed. RESULTS: No wound-related complications requiring readmission, intravenous antibiotics, or reoperation were encountered at a median 3-month follow-up. There were also no surgical site infections, dehiscences, or cerebrospinal fluid leaks. Fifty-one patients (57.3%) had postoperative radiotherapy, 85 patients (93.4%) had perioperative steroids, and 56 patients (61.5%) had postoperative chemotherapy. Six patients (6.5%) were placed on a short course of oral antibiotics perioperatively due to concerns with initial scalp healing (ie, excessive scabbing at follow-up), none of whom progressed to infection or required further intervention. These are the cases where this technique is felt to have been most helpful by potentially preventing worse sequelae. One patient developed a shunt infection during this interval that required removal unrelated to the craniotomy site. CONCLUSION: Here we outline in detail the principles, design, and execution of incisions and closures with stairstep pericranial edges in supratentorial brain surgery. This technique was designed in consultation with plastic surgeons to provide an intact, vascularized layer of pericranium beneath the healing skin and over the bone graft/hardware to optimize wound healing conditions and prevent morbid sequelae in inevitable cases of poor initial healing. Early results are promising.

Surgical Treatment of Secondary Pneumothorax-Complicated Interstitial Lung Disease.

To investigate the feasibility of early surgical treatment and perioperative steroid use in patients with interstitial lung disease (ILD) complicated by pneumothorax. We retrospectively examined data, including patient characteristics, laboratory findings, surgical treatment details, postoperative complications, and deaths, of nine patients with ILD complicated by secondary pneumothorax. The patients had been treated at our hospital during the past 10 years. All nine patients were male (median age, 69.0 years). A total of nine patients had a histopathologic diagnosis of ILD after surgery. Of these, five were clinically diagnosed with ILD before surgery. Collagen disease was diagnosed in one case, drug-induced in one case, and idiopathic ILD (IILD) in three cases. All nine patients were diagnosed with postoperative ILD, including one case of collagen disease, one case of drug-induced, three cases of idiopathic pulmonary fibrosis (IPF)/cryptogenic fibrosing alveolitis, one case of nonspecific interstitial pneumonia (NSIP), and three cases of cryptogenic organizing pneumonia (COP). Regarding preoperative clinical characteristics, the performance status (PS) was 0 or 1 in all patients. Overall, three patients received oxygen (0-3 L/min), whereas steroids were administered to five patients. The mean drainage period was 23.5 days, and this was consistent with the time taken from pneumothorax occurrence to surgery. Video-assisted thoracic surgery (VATS) and thoracoscopic-assisted surgery were performed in seven and two patients, respectively. No postoperative recurrence or surgery-related deaths occurred. Early surgery for secondary pneumothorax complicated by ILD may be a viable option for patients in good preoperative condition. For patients who are preoperatively treated with steroids, continued use of steroids should be carefully considered.

Safety of withholding perioperative steroids for patients with pituitary resection with an intact hypothalamus-pituitary-adrenal axis: A meta-analysis of randomized clinical trials

IntroductionSeveral observational studies have evaluated the effects of pre-operative steroids (STER) for transsphenoidal pituitary removal in patients with an intact hypothalamus-pituitary-adrenal axis. However, a consensus built upon randomized studies has not been previously performed. PurposeTo comprehensively evaluate the clinical effects of patients receiving STER when compared to those not receiving steroids (NOSTER) in transsphenoidal pituitary resection, a meta-analysis of randomized clinical trials (RCT) was conducted. MethodsA systematic review of the literature of RCTs comparing STER and NOSTER was performed in accordance with the PRISMA guidelines. Databases, including PUBMED, Cochrane Library, Web of Science, and Embase were queried. The primary outcomes were adrenal insufficiency (AI) and diabetes insipidus (DI) post-operatively. ResultsA total of 4 final studies were included, in which 530 total patients were analyzed. The meta-analysis suggested that there was no significant difference between STER and NOSTER groups post-operatively related to transient AI (RR= 0.83, 95% CI [0.51–1.35], p = 0.45; I² = 52%), permanent AI (RR= 0.97, 95% CI [0.41–2.31], p = 0.95; I² = 0%), and permanent DI (RR= 0.62, 95% CI [0.16–2.33], p = 0.48; I² = 0%). Nevertheless, STER group had significantly lower rates of transient DI (RR= 0.60, 95% CI [0.38–0.95], p = 0.03; I² = 5%), and post-op hyponatremia (RR = 0.49, 95% CI [0.28–0.87], p = 0.02; I² = 0%). ConclusionThis study demonstrates evidence from RCTs that patients receiving pre-operative STER are both safe and effective pre-operatively for resection of pituitary adenomas with an intact hypothalamus-pituitary-adrenal axis.

Cochlear implant surgery facilitates intracochlear distribution of perioperative systemic steroids

Background Systemically administered steroids are widely utilised for hearing preservation therapies. More recently, steroids have been administered to achieve hearing protection after cochlear implant surgery. Currently there is a lack of understanding as to which administration route offers most therapeutic efficacy, local or systemic administration. Paramount to this are observations in animal studies that systemic administration following implantation offers hearing protection and reduced cochlear fibrosis, despite observations that perilymphatic levels are up to 10-fold higher after local administration in non-implanted cochleae. Aims/Objectives This paper explores the impact that cochlear implantation and associated acute inflammation has on steroid distribution and uptake following systemic administration of dexamethasone. Material and Methods Eight guinea pigs received systemic dexamethasone 60 min prior to cochlear implantation. Implanted and contralateral non-implanted cochlea were harvested for tissue immunohistochemistry and detection of dexamethasone. Results Cochleostomy with scala tympani implantation resulted in a significant increase in cochlear dexamethasone signal. This was most notable at the organ of Corti, stria vascularis, and blood product in the scala tympani. Conclusions and Significance This study demonstrates that the inner ear distribution of systemically administered steroids is enhanced following surgery for cochlear implantation and provides rationale for systemic perioperative steroids in hearing preservation surgery.

Evidence of Hematoma Prevention After Facelift.

Hematoma is a common complication after facelift procedures. Multiple factors have been shown to increase the risk of hematoma formation such as male gender, anticoagulant medication use, perioperative hypertension, increased intrathoracic pressure, and operative technique. The purpose of this manuscript is to provide an overview of existing literature to provide surgeons with evidence-based recommendations on how to minimize hematoma risk during facelift surgery. A literature search for hematoma and facelift surgery was performed which identified 478 unique manuscripts. Abstracts were reviewed, excluding articles not describing facelift surgery, those written before 1970, studies with a sample size less than 5 patients, non-English studies, and those that did not provide postoperative hematoma rates. Forty-five articles were included in this text with their recommendations. Measures such as the prophylactic management of pain, nausea, and hypertension, the use of fibrin glue tissue sealants, the use of local anesthesia over general anesthesia, and strict blood pressure control of at least <140mmHg were found to significantly reduce hematoma formation. The use of quilting sutures has shown benefit in some high-risk patients. Measures such as drains, compression dressings, perioperative use of selective serotonin reuptake inhibitors (SSRIs), and perioperative steroids had no significant effect on hematoma formation. In addition to appropriate patient selection and careful intraoperative hemostasis, many adjunctive measures have been shown to reduce post-operative hematoma formation in facelift procedures.

P.102 Weighing the risks and benefits of perioperative steroids in the surgical treatment of malignant brain tumours

Background: Steroids are widely used in medicine because of their anti-inflammatory and immunosuppressive properties; however, they have numerous adverse effects. In neuro-oncology, dexamethasone is the first-line treatment for vasogenic edema caused by malignant brain tumours. This retrospective chart review investigated the risks and benefits of perioperative steroids in the surgical treatment of malignant brain tumours. Methods: All patients (age ≥ 18 years) who underwent a craniotomy for the treatment of a malignant brain tumour at Windsor Regional Hospital between 2012 and 2020 were assessed for eligibility for this retrospective study. Baseline patient characteristics, cumulative perioperative steroid dose, and postoperative outcomes were recorded from electronic medical records (n = 362). Statistical analysis was performed using SPSS. Results: Patients who received a higher cumulative perioperative steroid dose (≥ 80 mg) had a significantly higher rate of postoperative complications compared to those who received a lower dose. These included wound dehiscence, postoperative brain edema on imaging, unplanned return to the operating room, and readmission within 30 days. Conclusions: Steroids are important medications in neuro-oncology, but they are not without potential complications. The findings of this study highlight the need for careful consideration when using steroids in patients undergoing surgical treatment of a malignant brain tumour.

Predictors of Delayed Hyponatraemia After Surgery for Pituitary Tumour.

Delayed hyponatraemia(DH) is a common complication following trans-sphenoidal surgery(TSS) for pituitary tumour. We evaluated the prevalence of DH following TSS, and assessed the factors associated with DH, including early post-operative diabetes insipidus(EPDI). This retrospective study included 100 TSS for pituitary tumours in 98 patients, over a period of 26 months. Subjects were divided into two groups: those who developed hyponatraemia and those who did not develop hyponatraemia, during post-operative days 4 to 14. The clinical characteristics and peri-operative parameters were compared between the two groups, to identify factors predicting DH. The mean age of the patients was 42.0±13.6 years, 58 (59%) were females and 61 (61%) had functional tumours. Thirty-six patients(36%) developed DH following TSS of whom majority(58%) were diagnosed on post-operative days 7 and 8; only 8/36 (22%) were symptomatic. Syndrome of inappropriate antidiuretic hormone secretion(SIADH) was found to be the most common aetiology of DH. On logistic regression analysis, intra-operative cerebrospinal fluid(CSF) leak (OR 5.0; 95% CI 1.9-13.8; p=0.002), EPDI (OR 3.4; 95% CI 1.3-9.2; p=0.015) and peri-operative steroid use (OR 3.6; 95% CI 1.3-9.8; p=0.014) were found to be significantly associated with DH. In conclusion, EPDI, intra-operative CSF leak and peri-operative steroid use were significant predictors of DH. EPDI predicts moderate to severe hyponatraemia with 80% specificity but has low sensitivity(47%). As most patients have asymptomatic hyponatraemia, serum sodium measurement on POD 7 to 10 would be helpful to identify DH in patients at increased risk.

High adherence to enhanced recovery pathway independently reduces major morbidity and mortality rates after colorectal surgery: a reappraisal of the iCral2 and iCral3 multicenter prospective studies

Background: Enhanced recovery after surgery (ERAS) offers lower overall morbidity rates and shorter hospital stay after colorectal surgery (CRS); high adherence rates to ERAS may significantly reduce major morbidity (MM), anastomotic leakage (AL), and mortality (M) rates as well. Methods: Prospective enrollment of patients submitted to elective CRS with anastomosis in two separate 18- and 12-month periods among 78 surgical centers in Italy from 2019 to 2021. Adherence to ERAS pathway items was measured upon explicit criteria in every case. After univariate analysis, independent predictors of primary endpoints (MM, AL, and M rates) were identified through logistic regression analyses, presenting odds ratios (OR) and 95% confidence intervals. Results: An institutional ERAS status was declared by 48 out of 78 (61.5%) participating centers. The median overall adherence to ERAS was 75%. Among 8,359 patients included in both studies, MM, AL, and M rates were 6.3%, 4.4%, and 1.0%, respectively. Several patient-related and treatment-related variables showed independently higher rates for primary endpoints: male gender, American Society of Anesthesiologists class III, neoadjuvant treatment, perioperative steroids, intra- and/or postoperative blood transfusions, length of the operation &gt;180’, surgery for malignancy. On the other hand, ERAS adherence &gt;85% independently reduced MM (OR, 0.91) and M (OR, 0.25) rates, whereas no mechanical bowel preparation independently reduced AL (OR, 0.68) rates. Conclusions: Among other patient- or treatment-related variables, ERAS adherence &gt;85% independently reduced MM and M rates, whereas no mechanical bowel preparation independently reduced AL rates after CRS.

Uncovering the molecular landscape of meningiomas and the impact of perioperative steroids on patient survival.

The current literature on meningioma reveals a gap in knowledge regarding the impact of genetic factors on patient survival. Furthermore, there is a lack of data on the relationship between the perioperative use of corticosteroids and patient survival in meningioma patients. Our study aims to overcome these gaps by investigating the correlation between genetic factors and overall survival and the effect of postoperative corticosteroids and other clinical characteristics on patient outcomes in meningioma patients. A retrospective analysis of the medical records of 85 newly diagnosed meningioma patients treated from 2016 to 2017 with follow-up until December 2022 was performed. NF2 mutations occurred in 60% of tumors, AKT1 mutations in 8.2%, and TRAF7 mutations in 3.6%. Most tumors in the parasagittal region had the NF2 mutation. On the other hand, almost all tumors in the sphenoid ridge area did not have the NF2 mutation. AKT-1-mutated meningiomas had more frequent peritumoral edema. Patients who received steroids perioperatively had worse overall survival (OS) than those without steroids (p = 0.034). Moreover, preoperative peri-meningioma edema also was associated with worse OS (p < 0.003). Contrarily, NF2 mutations did not influence survival. The combination of clinical, pathomorphological, and genetic data allows us to characterize the tumor better and assess its prognosis. Corticosteroids perioperatively and peri-meningioma edema were associated with shorter OS, according to our study. Glucocorticoids should be used judiciously for the shortest time required to achieve symptomatic relief.
