Association between frailty, long-term mortality and functional outcomes for older adults undergoing emergency laparotomy.

BACKGROUND: An increasing number of older patients are undergoing emergency laparotomy (EL). Frailty is thought to contribute to adverse outcomes in this group. The best method to assess frailty and impacts on long-term mortality and other important functional outcomes for older EL patients have not been fully explored. METHODS: A prospective multicenter study of older EL patients was conducted across four hospital sites in New Zealand from August 2017 to September 2022. The Clinical Frailty Scale (CFS) was used to measure frailty-defined as a CFS of ≥5. Primary outcomes were 30-day and one-year mortality. Secondary outcomes were postoperative morbidity, admission for rehabilitation, and increased care level on discharge. A multivariate logistic regression analysis was conducted, adjusting for age, sex, and ethnicity. RESULTS: A total of 629 participants were included. Frailty prevalence was 14.6%. Frail participants demonstrated higher 30-day and 1-year mortality-20.7% and 39.1%. Following adjustment, frailty was directly associated with a significantly increased risk of short- and long-term mortality (30-day aRR 2.6, 95% CI 1.5, 4.3, p = <0.001, 1-year aRR 2.0, 95% CI 1.5, 2.8, p < 0.001). Frailty was correlated with a 2-fold increased risk of admission for rehabilitation and propensity of being discharged to an increased level of care, complications, and readmission within 30 days. CONCLUSION: Frailty was associated with increased risk of postoperative mortality up to 1-year and other functional outcomes for older patients undergoing EL. Identification of frailty in older EL patients aids in patient-centered decision-making, which may lead to improvement in outcomes.

Consensus-defined sarcopenia predicts adverse outcomes after elective abdominal surgery: meta-analysis.

BACKGROUND: Sarcopenia refers to the progressive age- or pathology-associated loss of skeletal muscle. When measured radiologically as reduced muscle mass, sarcopenia has been shown to independently predict morbidity and mortality after elective abdominal surgery. However, the European Working Group on Sarcopenia in Older People (EWGSOP) recently updated their sarcopenia definition, emphasizing both low muscle 'strength' and 'mass'. The aim of this systematic review and meta-analysis was to determine the prognostic impact of this updated consensus definition of sarcopenia after elective abdominal surgery. METHODS: MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched for studies comparing prognostic outcomes between sarcopenic versus non-sarcopenic adults after elective abdominal surgery from inception to 15 June 2022. The primary outcomes were postoperative morbidity and mortality. Sensitivity analyses adjusting for confounding patient factors were also performed. Methodological quality assessment of studies was performed independently by two authors using the QUality in Prognosis Studies (QUIPS) tool. RESULTS: Twenty articles with 5421 patients (1059 sarcopenic and 4362 non-sarcopenic) were included. Sarcopenic patients were at significantly greater risk of incurring postoperative complications, despite adjusted multivariate analysis (adjusted OR 1.56, 95 per cent c.i. 1.39 to 1.76). Sarcopenic patients also had significantly higher rates of in-hospital (OR 7.62, 95 per cent c.i. 2.86 to 20.34), 30-day (OR 3.84, 95 per cent c.i. 1.27 to 11.64), and 90-day (OR 3.73, 95 per cent c.i. 1.19 to 11.70) mortality. Sarcopenia was an independent risk factor for poorer overall survival in multivariate Cox regression analysis (adjusted HR 1.28, 95 per cent c.i. 1.13 to 1.44). CONCLUSION: Consensus-defined sarcopenia provides important prognostic information after elective abdominal surgery and can be appropriately measured in the preoperative setting. Development of targeted exercise-based interventions that minimize sarcopenia may improve outcomes for patients who are undergoing elective abdominal surgery.

Weekend effect in emergency laparotomy: a propensity score-matched analysis.

BACKGROUND: The 'weekend effect' is the term given to the observed discrepancy regarding patient care and outcomes on weekends compared to weekdays. This study aimed to determine whether the weekend effect exists within Aotearoa New Zealand (AoNZ) for patients undergoing emergency laparotomy (EL), given recent advances in management of EL patients. METHODS: A cohort study was conducted across five hospitals, comparing the outcomes of weekend and weekday acute EL. A propensity-score matched analysis was used to remove potential confounding patient characteristics. RESULTS: Of the 487 patients included, 132 received EL over the weekend. There was no statistically significant difference between patients undergoing EL over the weekend compared to weekdays. Mortality rates were comparable between the weekday and weekend cohorts (P = 0.464). CONCLUSIONS: These results suggest that modern perioperative care practice in New Zealand obviates the 'weekend' effect.

Have Factors Influencing Female Medical Students' Intention to Pursue a Career in Surgery Changed over the Last 10 Years? A Systematic Review.

In 2012, a systematic review reported on factors influencing female medical students, career intentions for surgery. This current review is a direct follow-up of that article with the aim of assessing whether factors affecting female medical student career choices have changed over the last decade. This review has identified access to research opportunities as a new factor that can be used to promote female medical student and trainee interest in surgery. Other factors have largely remained unchanged over the last 10 years, such as lack of access to leave, part-time work, and same-gender role models.

Short- and long-term impact of sarcopenia on outcomes after emergency laparotomy: A systematic review and meta-analysis.

BACKGROUND: Sarcopenia refers to the progressive age and pathology-associated loss of skeletal muscle, which has been shown to independently predict mortality in patients undergoing major elective surgery. Emergency laparotomy is commonly performed for a range of procedures and is associated with high rates of mortality. However, the prognostic utility of sarcopenia after emergency laparotomy remains unknown. The aim of this study was to compare short and long-term survival between patients with and without sarcopenia undergoing emergency laparotomy. METHODS: MEDLINE, EMBASE, and Scopus databases were systematically searched for articles comparing survival outcomes between adults with and without radiologically defined sarcopenia after emergency gastrointestinal surgery regardless of indication and approach (open/laparoscopic). The primary outcome was postoperative mortality. Sensitivity analysis of adjusted multivariate analyses was performed. RESULTS: Twenty articles comprising 6,737 patients were included. Sarcopenia was most commonly assessed using axial abdominal computerized tomography at L3, although cut-off thresholds were heterogeneous and rarely sex-specific. Postoperative mortality was higher among patients with sarcopenia than without in the in-hospital setting, and at 30- and 90-day follow-up on univariate but not on multivariate meta-analysis. However, mortality was significantly higher among sarcopenic cohorts in the 1-year (odds ratio 2.8, 95% confidence interval: 1.5-5.6; P = .002) follow-up period, despite adjusting for confounding preoperative and patient factors. CONCLUSION: The meta-analysis has shown sarcopenia to provide useful long-term prognostic information following emergency laparotomy. This may aid with preoperative risk assessment, patient counseling, and in perioperative decision-making for patients undergoing emergency laparotomy.

A systematic review and network meta-analysis comparing treatments for anal fissure.

BACKGROUND: There are multiple treatments for anal fissures. These range from medical treatment to surgical procedures, such as sphincterotomy. The aim of this study was to compare the relative clinical outcomes and effectiveness of interventional treatments for anal fissure. METHODS: Randomized controlled trials were identified by means of a PRISMA-compliant systematic review using the Medline, EMBASE, and CENTRAL databases. Inclusion criteria were randomized controlled trials comparing treatments for anal fissure. A Bayesian network meta-analysis was performed using BUGSnet package in R. Outcomes of interest were healing (6-8-, 10-16-, and >16-week follow-up), symptom recurrence, pain (measured on a visual analog scale), and fecal or flatus incontinence. PROPSERO Registration: CRD42021229615. RESULTS: Sixty-nine randomized controlled trials were included in the analysis. Lateral sphincterotomy remains the treatment with the highest odds of healing compared to botulinum toxin and medical therapy at all follow-up time points. There was no significant difference in healing between botulinum toxin and medical therapy at any time point. Advancement flap showed similar effectiveness compared to lateral sphincterotomy. Medical treatment and botulinum toxin had the highest pain scores at follow-up. Sphincterotomy had the highest odds of fecal and flatus incontinence. CONCLUSION: Lateral sphincterotomy had the highest rates of healing and should be considered as the definitive treatment after failed initial therapy with botulinum toxin or medical treatment. Botulinum toxin was equally effective compared to medical treatment. Advancement flap shows similar effectiveness compared to lateral sphincterotomy, but more studies are needed to evaluate its efficacy.

Patient Experiences of the Emergency Laparotomy Pathway: A Qualitative Study.

INTRODUCTION: Emergency laparotomy (EL) is a commonly performed operation with high rates of morbidity and mortality. Despite a growing body of literature on outcomes from EL, there is sparse literature on the patient experience. The aim of this study is to capture the perspective of patients on their EL experience. Qualitative methodology is used as a platform to allow patients to express their personal experiences and ideas around the EL process. MATERIALS AND METHOD: Participants were consented as a part of a large observational study, established across the three public teaching hospitals in Auckland, New Zealand. Patients who had an EL within the past 4 months were recruited. A recorded interview was conducted either face-to-face or over the telephone, using questions formulated from a previous systematic review on EL outcomes. Transcripts were transported to NVivo and thematically analysed by two reviewers. RESULTS: Fifteen participants were interviewed. The majority of participants were female, New Zealand European and 65 or older. Five important themes were identified. Overall, participants expressed satisfaction with their interactions with hospital staff. However, they wanted more information about their condition, operation and what outcomes might occur. Participants also described post-operative priorities in the acute setting, as well as long-standing physical and emotional impacts. CONCLUSION: This study provides a better understanding of what is important to patients during the EL process. This information is important when considering ways to improve care and communication with patients undergoing EL.

Pilonidal sinus: is histological examination necessary?

BACKGROUND: Pilonidal sinus is a common pathology occurring in a number of sites including the gluteal cleft between the buttocks. Surgery is the principal mode of treatment with a variety of techniques proposed to cure the disease and prevent recurrence. The rate of malignant degeneration is estimated at 0.1% in patients with chronic pilonidal disease. A case series study of pilonidal sinus found that most patients with malignancy were over the age of 50 years and had had chronic pilonidal disease for several years. This study aimed to review the value of histological analysis of pilonidal sinus specimens. METHODS: A retrospective observational study was conducted of all patients who have undergone pilonidal sinus excision by the Department of General Surgery at Counties Manukau District Health Board in the past 10 years. RESULTS: This study reviewed 1324 admissions with a pilonidal disease requiring surgical management. There were 325 pilonidal resections with 320 histological specimens analysed. Pilonidal sinus was detected in 312 specimens, eight others were benign and there were no specimens with malignancy. CONCLUSION: No cases of malignancy were found in all pilonidal specimens that were sent for histological review. Routine histological examination of pilonidal sinus specimens appears to be unnecessary; however, it should be considered in patients over the age of 50 years.

Topical analgesia following excisional haemorrhoidectomy: a systematic review and meta-analysis of randomised controlled trials.

PURPOSE: Post-operative pain following excisional haemorrhoidectomy poses a particular challenge for patient recovery, as well as a burden on hospital resources. There appears to be an increasing role for topical agents to improve this pain, but their efficacy and safety have not been fully assessed. This systematic review aims to assess all topical agents used for pain following excisional haemorrhoidectomy. METHODS: The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two authors independently assessed MEDLINE, EMBASE, and CENTRAL databases to 27 June 2019. All randomised controlled trials (RCTs) in English that investigated topical agents following excisional haemorrhoidectomy were included. Meta-analysis was performed using Review Manager, version 5.3. RESULTS: A total of 3639 records were identified. A final 32 RCTs were included in the qualitative analysis. Meta-analysis was performed on 9 RCTs that investigated glyceryl trinitrate (GTN) (5 for diltiazem, 2 for metronidazole and 2 for sucralfate). There were mixed significant changes in pain for GTN compared with placebo. Diltiazem resulted in significant reduction of pain on post-operative days 1, 2, 3 and 7 (p < 0.00001). Metronidazole resulted in significant reduction of pain on days 1 (p = 0.009), 7 (p = 0.002) and 14 (p < 0.00001). Sucralfate resulted in signification reduction of pain on days 7 and 14 (both p < 0.00001). CONCLUSION: Topical diltiazem, metronidazole and sucralfate appear to significantly reduce pain at various timepoints following excisional haemorrhoidectomy. GTN had mixed evidence. Several single trials identified other promising topical analgesics.

A Systematic Review of Intra-pancreatic Fat Deposition and Pancreatic Carcinogenesis.

BACKGROUND: Excess adiposity is considered causally related to pancreatic cancer. While most knowledge on the topic comes from studies on general and visceral adiposity, the role of intra-pancreatic fat deposition in pancreatic carcinogenesis just begins to be elucidated. The aim was to conduct a comprehensive systematic review of clinical studies on intra-pancreatic fat deposition in individuals with pancreatic cancer or pre-malignant lesions. METHODS: A literature search was conducted independently by two reviewers using three electronic databases. Studies were included if they reported on intra-pancreatic fat deposition determined based on modern radiology or histology. Summary estimates were presented as pooled prevalence or relative risk and 95% confidence interval. RESULTS: A total of 13 studies (encompassing 2178 individuals) were included. The pooled prevalence of intra-pancreatic fat deposition in individuals with pancreatic cancer or pre-malignant lesions was 52% (95% confidence interval, 38-66%). The presence of pancreatic cancer or pre-malignant lesions was associated with a significantly increased risk of intra-pancreatic fat deposition (relative risk 2.78 (95% confidence interval, 1.56-4.94, p < 0.001). CONCLUSION: Individuals with pancreatic cancer or pre-malignant lesions are characterized by increased intra-pancreatic fat deposition. There are sound grounds for conceptually viewing intra-pancreatic fat deposition as a combination of fat accumulation in the pancreas (due to expansion of excess visceral fat) and fatty replacement of the pancreas (due to changes in cellular identity within the pancreas). Guidelines on reporting intra-pancreatic fat deposition need to be developed with a view to informing a comprehensive and standardized characterization of this clinical entity in future studies.

Use of a 360-degree evaluation in the outpatient setting: the usefulness of nurse, faculty, patient/family, and resident self-evaluation.

BACKGROUND: Faculty have traditionally evaluated resident physician professionalism and interpersonal skills without input from patients, family members, nurses, or the residents themselves. The objective of our study was to use "360-degree evaluations," as suggested by the Accreditation Council for Graduate Medical Education (ACGME), to determine if nonfaculty ratings of resident professionalism and interpersonal skills differ from faculty ratings. METHODS: Pediatrics residents were enrolled in a hospital-based resident continuity clinic during a 5-week period. Patient/families (P/Fs), faculty (MD [doctor of medicine]), nurses (RNs [registered nurses]), and residents themselves (self) completed evaluator-specific evaluations after each clinic session by using a validated 10-item questionnaire with a 5-point Likert scale. The average Likert score was tallied for each questionnaire. Mean Likert scale scores for each type of rater were compared by using analysis of variance, text with pair-wise comparisons when appropriate. Agreement between rater types was measured by using the Pearson correlation. RESULTS: A total of 823 evaluations were completed for 66 residents (total eligible residents, 69; 95% participation). All evaluators scored residents highly (mean Likert score range, 4.4 to 4.9). However, MDs and RNs scored residents higher than did P/Fs (mean scores: MD, 4.77, SD [standard deviation], 0.32; RN, 4.85, SD, 0.30; P/F, 4.53, SD, 0.96; P < .0001). MD and RN scores also were higher than residents' self-evaluation scores, but there was no difference between self-scores and P/F scores (average resident self-score, 4.44, SD, 0.43; P < .0001 compared to MD and RN; P  =  .19 compared to P/F). Correlation coefficients between all combinations of raters ranged from -0.21 to 0.21 and none were statistically significant. CONCLUSION: Our study found high ratings for resident professionalism and interpersonal skills. However, different members of the health care team rated residents differently, and ratings are not correlated. Our results provide evidence for the potential value of 360-degree evaluations.
