Exploring the Relationship between Biologics and Postoperative Surgical Morbidity in Ulcerative Colitis: A Review

Background: With the paradigm shift related to the overspread use of biological agents in the treatment of inflammatory bowel diseases (IBD), several questions emerged from the surgical perspective. Whether the use of biologicals would be associated with higher rates of postoperative complications in ulcerative colitis (UC) patients still remains controversial. Aims: We aimed to analyze the literature, searching for studies that correlated postoperative complications and preoperative exposure to biologics in UC patients, and synthesize these data qualitatively in order to check the possible impact of biologics on postoperative surgical morbidity in this population. Methods: Included studies were identified by electronic search in the PUBMED database according to the PRISMA (Preferred Items of Reports for Systematic Reviews and Meta-Analysis) guidelines. The quality and bias assessments were performed by MINORS (methodological index for non-randomized studies) criteria for non-randomized studies. Results: 608 studies were initially identified, 22 of which were selected for qualitative evaluation. From those, 19 studies (17 retrospective and two prospective) included preoperative anti-TNF. Seven described an increased risk of postoperative complications, and 12 showed no significant increase postoperative morbidity. Only three studies included surgical UC patients with previous use of vedolizumab, two retrospective and one prospective, all with no significant correlation between the drug and an increase in postoperative complication rates. Conclusions: Despite conflicting results, most studies have not shown increased complication rates after abdominal surgical procedures in patients with UC with preoperative exposure to biologics. Further prospective studies are needed to better establish the impact of preoperative biologics and surgical complications in UC.

Post Operative Complications

Background and aims: Biologic therapy has emerged as an effective modality amongst the medical treatment options available for ulcerative colitis (UC). However, its impact on post-operative care in patients with UC is still debatable. This review evaluates the risk of post-operative complications following biologic treatment in patients with UC. Methods: A systematic search of the relevant databases was conducted with the aim of identifying studies that compared the post-operative complication rates of UC patients who were either exposed or not exposed to a biologic therapy prior to their surgery. Outcomes of interest included both infection-related complications and overall surgical morbidity. Pooled odds-ratio (OR) and 95% confidence intervals (CI) were calculated using Review Manager 5.3. Results: In all, 20 studies, reviewing a total of 12,494 patients with UC, were included in the meta-analysis. Of these, 2254 patients were exposed to a biologic therapy prior to surgery. The pooled ORs for infection-related complications ( n = 8067) and overall complications ( n = 11,869) were 0.98 (95% CI 0.66–1.45) and 1.14 (95% CI 1.04–1.28), respectively, which suggested that there was no significant association between the use of pre-operative biologic therapy and post-operative complications. Interestingly, the interval between the last dose of biologic therapy and surgery did not influence the risk of having a post-operative infection. Conclusions: This meta-analysis suggests that pre-operative biologic therapy does not increase the overall risk of having post-operative infection-related or other complications.

BACKGROUND: The impact ofClostridium difficileinfections among ulcerative colitis (UC) patients is well characterized. However, there is little knowledge regarding the association betweenC difficileinfections and postoperative complications among UC patients.OBJECTIVE: To determine whetherC difficileinfection is associated with undergoing an emergent colectomy and experiencing postoperative complications.METHODS: The present population-based case-control study identified UC patients admitted to Calgary Health Zone hospitals for a flare between 2000 and 2009.C difficiletoxin tests ordered in hospital or 90 days before hospital admission were provided by Calgary Laboratory Services (Calgary, Alberta). Hospital records were reviewed to confirm diagnoses and to extract clinical data. Multivariate logistic regression analyses were performed among individuals tested forC difficileto examine the association betweenC difficileinfection and emergent colectomy and diagnosis of any postoperative complications and, secondarily, an infectious postoperative complication. Estimates were presented as adjusted ORs with 95% CIs.RESULTS:C difficilewas tested in 278 (58%) UC patients and 6.1% were positive.C difficileinfection was associated with an increased risk for emergent colectomy (adjusted OR 3.39 [95% CI 1.02 to 11.23]). Additionally, a preoperative diagnosis ofC difficilewas significantly associated with the development of postoperative infectious complications (OR 4.76 [95% CI 1.10 to 20.63]).CONCLUSION:C difficilediagnosis worsened the prognosis of UC by increasing the risk of colectomy and postoperative infectious complications following colectomy. Future studies are needed to explore whether early detection and aggressive management ofC difficileinfection will improve UC outcomes.

Abstract Aim Anterior Lumbar Interbody Fusion is a procedure growing in popularity for conditions including degenerative disc disease, and discogenic back pain. Obesity is a significant risk factor in the development of back pain, with patients with raised BMIs at increased of complications using the posterior approach. This review aims to evaluate the risk profile of this patient cohort using the anterior approach for lumbar interbody fusion. Method A systematic review of the search databases Pubmed; google scholar; and OVID Medline was carried out between September 2020-November 2020. Studies evaluating the risks associated with obesity during Anterior Lumbar Interbody Fusion (ALIF) were identified and included for review according to PRISMA guidelines. Studies eligible for inclusion were agreed by two independent reviewers. Meta-analysis was used to compare intra- and postoperative complications in patients with increased BMI during ALIF. Results Search terms yielded 435 articles for evaluation. 13 studies were included in this review after applying inclusion and exclusion criteria. Meta-analysis of studies demonstrated a significantly increased risk profile for overall complications in the obese patient cohort (CI = 0.04-0.16, p = 0.002) with significant heterogeneity (I2=86%). Patients with increased BMI were not significantly more likely to develop Vascular complications (CI= -.03-0.02, p = 0.62). Simple pooling demonstrated significant association between increased BMI and blood loss. Conclusions Obesity was demonstrated to have an impact on overall complication rates in Anterior Lumbar Interbody Fusion procedures, with postoperative complications including wound infections and lower fusion rates more common in patients in increased BMIs.

ABSTRACT BACKGROUND In many patients, the diagnosis of Crohn’s disease (CD) is made during surgery for appendicitis in urgent settings. Intraoperative diagnosis can be challenging in certain cases, especially for less experienced surgeons. OBJECTIVE: Review of the literature searching for scientific evidence that can guide surgeons through optimal management of ileocecal CD found incidentally in surgery for acute appendicitis (AA). METHODS: Included studies were identified by electronic search in the PubMed database according to the Preferred Items of Reports for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The quality and bias assessments were performed by Methodological Index for Non-Randomized Studies (MINORS) criteria for non-randomized studies. RESULTS: A total of 313 studies were initially identified, six of which were selected (all retrospective) for qualitative assessment (two studies were comparative and four only descriptive case series). Four studies identified a high rate of complications when appendectomy or ileocolectomy were performed and in only one, there was no increased risk of postoperative complications with appendectomy. In the sixth study, diarrhea, previous abdominal pain, preoperative anemia and thrombocytopenia were independent predictors for CD in patients previously operated for suspected AA. CONCLUSION: Despite the paucity of data and low quality of evidence, a macroscopically normal appendix should be preserved in the absence of complicated disease when CD is suspected in surgery for AA. Ileocecal resections should be reserved for complicated disease (inflammatory mass, ischemia, perforation or obstruction). Further prospective studies are needed to confirm these claims.

Background and Aims: Diabetes mellitus (DM), poor glycaemic control and raised body mass index (BMI) have been associated with postoperative complications in arthroplasty, although the relative importance of these factors is unclear. We describe the prevalence of DM in elective hip arthroplasty in a UK centre, and evaluate the impact of these factors. Methods: We analysed retrospective data for DM patients undergoing arthroplasty over a 6-year period and compared with non-diabetic matched controls (1 DM patient: 5 controls). DM was present in 5.7% of hip arthroplasty patients (82/1443). Results: Postoperative complications occurred in 12.2% of DM patients versus 12.9% of controls ( p = 1.000); surgical complications were present in 6.1% of those with DM and 2.4% of controls ( p = 0.087), while medical complications occurred in 8.5% of DM patients versus 10.7% of controls ( p = 0.692). Complications developed in 23.1% of DM patients with poor glycaemic control (HbA1c > 53 mmol/mol) versus 9.8% with good control ( p = 0.169). In DM patients and controls combined, complications occurred in 16.3% of obese patients versus 10.0% of non-obese patients ( p = 0.043). In the DM cohort, 13.7% of overweight patients had complications versus 0% with a normal or low BMI ( p = 0.587). Conclusions: DM rates were lower than expected, and glycaemic control was good. Overall complication rates were unrelated to the presence of DM or to glycaemic control, although surgical complications were observed more frequently in those with DM and poor glycaemic control was uncommon within our cohort. Complications were more frequent in those with a higher BMI. Whether some patients with DM but without an increased risk of complications are currently being excluded from surgery requires exploration.

The Impact

Background: Liver transplant is frequently performed at night due to the unpredictability of organ procurement and reduction of Cold Ischemia Time (CIT). Previous study reported a doubled mortality Hazard Ratio (HR) of early death and increased postoperative complications in nighttime liver transplant. This study aims to evaluate the impact of nighttime operation on patients’ survival and postoperative complications by using meta-analysis. Methods: We performed a systematic review of the PubMed database and identified five eligible studies. Three time points (30 days, 90 days and 1 year) were explored in patients’ survival by using pooled HR. Four types of postoperative complications (vascular, biliary tract, wound and primary graft non-function) were investigated by using pooled Odds Ratio (OR). Publication bias was also performed. Results: Our study results were contradicting with the previous report and yielded no significant difference with a HR=0.98 (95% CI=0.89-1.06) on 30 days, HR=1.12 (95% CI=0.89-1.35) on 90 days and HR=1.07 (95% CI=0.95-1.18) on 1 year in nighttime procedure. Consistent with the result of patients’ survival, no significant result was found in postoperative complications evaluation as well. None of the four complications demonstrated significant result. And we failed to detect any significant publication bias. Conclusions: Based on current evidence, nighttime liver transplantations do not degrade patients’ survival or increase postoperative complications risk compared with daytime operations.

Abstract Background The impact of body compositions on surgical results is controversially discussed. This study examined whether visceral obesity, sarcopenia or sarcopenic obesity influence the outcome after hepatic resections of synchronous colorectal liver metastases. Methods Ninety-four consecutive patients with primary hepatic resections of synchronous colorectal metastases were identified from a single center database between January 2013 and August 2018. Patient characteristics and 30-day morbidity were retrospectively analyzed. Body fat and skeletal muscle were calculated by planimetry from single-slice CT images at the level of L3. Results Fifty-nine patients (62.8%) underwent minor hepatectomies, and 35 patients underwent major resections (37.2%). Postoperative complications occurred in 60 patients (62.8%) including 35 patients with major complications (Clavien–Dindo grade III–V). The mortality was nil at 30 days and 2.1% at 90 days. The body mass index showed no influence on postoperative outcomes (p = 1.0). Visceral obesity was found in 66 patients (70.2%) and was significantly associated with overall and major complication rates (p = .002, p = .012, respectively). Sarcopenia was observed in 34 patients (36.2%) without a significant impact on morbidity (p = .461), however, with longer hospital stay. Sarcopenic obesity was found in 18 patients (19.1%) and was significantly associated with postoperative complications (p = .014). Visceral obesity, sarcopenia and sarcopenic obesity were all identified as significant risk factors for overall postoperative complications. Conclusion Visceral obesity, sarcopenic obesity and sarcopenia are independent risk factors for overall complications after resections of CRLM. Early recognition of extremes in body compositions could prompt to perioperative interventions and thus improve postoperative outcomes.

Abstract Introduction Distal radius fractures are common and trends for fixation have changed with increased use of volar locking plates in recent time. A meta-analysis will summarise the best evidence for treatment. Method A systematic review was conducted using PRISMA methodology to identify studies that reported clinical and/or radiological outcomes in patients with AO type C distal radius fractures when treated with external fixation versus ORIF. Results 10 randomised trials were included in this review, reporting on 967 patients. Clinical outcomes are in favour of volar plating at 3 months post-operation, but no difference between the two groups is seen at 6 or 12 months. Analysis of complication rates shows a minute increase in risk-ratio for volar plating versus external fixation. Subgroup analysis showed significantly higher re-operations after plate fixation and significantly higher infection after external fixation. Conclusions Internal fixation of complex distal radius fractures confers an improved clinical outcome at early follow up only and a minimally increased risk of complications. The improved grip strength with volar plating is only superior at early follow up and no long-term superiority is seen with either intervention. The type of surgery in this injury type therefore remains at the surgeon’s consideration on a case-by-case basis.

AbstractIncidence of hip fractures has remained unchanged during the pandemic with overlapping vulnerabilities observed in patients with hip fractures and those infected with COVID-19. We aimed to investigate the independent impact of COVID-19 infection on the mortality of these patients. Healthcare databases were systematically searched over 2-weeks from 1st–14th November 2020 to identify eligible studies assessing the impact of COVID-19 on hip fracture patients. Meta-analysis of proportion was performed to obtain pooled values of prevalence, incidence and case fatality rate of hip fracture patients with COVID-19 infection. 30-day mortality, excess mortality and all-cause mortality were analysed using a mixed-effects model. 22 studies reporting 4015 patients were identified out of which 2651 (66%) were assessed during the pandemic. An excess mortality of 10% was seen for hip fractures treated during the pandemic (OR 2.00, p = 0.007), in comparison to the pre-pandemic controls (5%). Estimated mortality of COVID-19 positive hip fracture patients was four-fold (RR 4.59, p < 0.0001) and 30-day mortality was 38.0% (HR 4.73, p < 0.0001). The case fatality rate for COVID-19 positive patients was 34.74%. Between-study heterogeneity for the pooled analysis was minimal (I2 = 0.00) whereas, random effects metaregression identified subgroup heterogeneity for male gender (p < 0.001), diabetes (p = 0.002), dementia (p = 0.001) and extracapsular fractures (p = 0.01) increased risk of mortality in COVID-19 positive patients.
