Preoperative assessment and optimisation prior to planned aortic aneurysm repair: a UK survey examining current practice and attitudes of vascular surgeons and vascular anaesthetists

BackgroundThe majority of those diagnosed with aortic aneurysm in the UK are older, multi-morbid patients. Decision-making as to who may benefit from intervention (open or endovascular aneurysm repair) is highly variable across the NHS (as is the mode of intervention), in part because there are no detailed guidelines or consensus on preoperative assessment. Thus, there is likely to be significant variation in the pre-operative assessment and optimisation of these patients.MethodsA survey was designed to understand current practice and attitudes of vascular surgeons and vascular anaesthetists in the UK regarding preoperative assessment and optimisation of patients undergoing elective aortic aneurysm repair. The survey was reviewed and validated by an expert panel, then distributed electronically to all vascular surgical and vascular anaesthetic leads in the UK.ResultsOverall, the response rate was 68%. The responses were varied between surgeons and anaesthetists, with differences reported in the preoperative assessment and optimisation of patients, the approach to shared decision-making, and the perioperative pathway.ConclusionsDespite initiatives such as Getting It Right First Time (GIRFT) and National Institute for Health and Care Excellence (NICE) guidelines, variation still exists between centres with some differences in opinion observed between surgeons and anaesthetists. These differences may be leading to duplication of work in the perioperative pathway, inconsistencies in how risk is assessed and communicated with consequent variation in patient care. Addressing these issues requires awareness and implementation of existing guidelines, transdisciplinary working, efficient data-driven pathways, and structured aortic aneurysm multi-disciplinary team to promote meaningful shared decision-making.

Nursing Interventions in the Perioperative Pathway of the Patient with Breast Cancer: A Scoping Review.

The decrease in average hospitalisation time and the increase in outpatient surgery in some types of breast cancer represent gains for the reduction of the negative impact of hospitalisation in women with breast cancer but are also a challenge for the organisation of nursing care to prepare women for surgery, reduce anxiety about the interventions, and ensure continuity of care in the postoperative period. The aim of this study is to identify nursing interventions present in the care provided to patients with breast cancer during the perioperative period. A scoping review was the method chosen to answer the research question: What are the specialised nursing interventions in the perioperative pathway of the patient with breast cancer? Inclusion and exclusion criteria were defined for the articles that were identified in the CINAHL and MEDLINE databases; later, additional sources were identified from the list of bibliographic references for each selected study. The final bibliographical sample consisted of seven articles, which allowed the identification of three key moments of nursing interventions in the perioperative period of patients with breast cancer: the preoperative consultation, the reception of the patient in the operating room, and the postoperative consultation. Factors such as psychological, emotional, and spiritual support, communication and patient-centred care, health education and surgical safety, and the definition of a perioperative pathway for these patients contribute significantly to patients' satisfaction and the improvement of their quality of life. The results of this study make it possible to establish recommendations for practise and for research, increasing the range of nurses' actions.

An Anaesthetist’s Prediction

Change and challenge are inevitable in cardiac anaesthesia. For patients undergoing cardiac interventions, technology, techniques, and procedures will evolve. These will be driven by the economics and expectations for more rapid recovery, less utilisation of theatre and intensive care unit resources, and earlier discharge with more reliance on “recovery in the home”. Older patients will have to manage significant comorbidities. The subspecialty will adapt but needs to demonstrate its role in the whole perioperative pathway. Cardiac anaesthesia has always led in many technologies - echocardiography will continue to evolve to provide greater insights into real-time cardiac structure and function, and to assess the effectiveness of the many new minimally invasive procedures. Monitoring for organ ischaemia or injury will improve, with approaches such as multi-wavelength oximetry to assess cerebral and other organ function. Point-of-care biomarkers for tissue health will be able to be assessed and guide interventions. Systemic inflammation needs to be modulated to improve delirium and cognitive impairment, atrial fibrillation, and coagulopathy outcomes. Genomics and proteomics, and more functional rather than structural diagnostics will allow better understanding of any underlying pathology and its risk of harm, to guide precise and individualised interventions. Risk assessment will be much more specific across all organ systems. Anaesthesia will be more tailored to the procedure and the patient than now. When all else has failed, heart and lung transplantation, extracorporeal membrane oxygenation, and mechanical cardiac support technologies and management will inevitably be refined.

Current Perioperative Care in Pancreatoduodenectomy: A Step-by-Step Surgical Roadmap from First Visit to Discharge.

Pancreaticoduodenectomy (PD) is a mainstay in the management of periampullary tumors. Treatment algorithms increasingly employ a multimodal strategy, which includes neoadjuvant and adjuvant therapies. However, the successful treatment of a patient is contingent on the execution of a complex operation, whereby minimizing postoperative complications and optimizing a fast and complete recovery are crucial to the overall success. In this setting, risk reduction and benchmarking the quality of care are essential frameworks through which modern perioperative PD care must be delivered. The postoperative course is primarily influenced by pancreatic fistulas, but other patient- and hospital-associated factors, such as frailty and the ability to rescue from complications, also affect the outcomes. A comprehensive understanding of the factors influencing surgical outcomes allows the clinician to risk stratify the patient, thereby facilitating a frank discussion of the morbidity and mortality of PD. Further, such an understanding allows the clinician to practice based on the most up-to-date evidence. This review intends to provide clinicians with a roadmap to the perioperative PD pathway. We review key considerations in the pre-, intra-, and post-operative periods.

Time requirements for perioperative glucose management using fully closed-loop versus standard insulin therapy: A proof-of-concept time-motion study.

To compare the time required for perioperative glucose management using fully automated closed-loop versus standard insulin therapy. We performed a time-motion study to quantify the time requirements for perioperative glucose management with fully closed-loop (FCL) and standard insulin therapy applied to theoretical scenarios. Following an analysis of workflows in different periods of perioperative care in elective surgery patients receiving FCL or standard insulin therapy upon hospital admission (pre- and intra-operatively, at the intermediate care unit and general wards), the time of process-specific tasks was measured by shadowing hospital staff. Each task was measured 20 times and its average duration in combination with its frequency according to guidelines was used to calculate the cumulative staff time required for blood glucose management. Cumulative time was calculated for theoretical scenarios consisting of elective minor and major abdominal surgeries (pancreatic surgery and sleeve gastrectomy, respectively) to account for the different care settings and lengths of stay. The FCL insulin therapy reduced the time required for perioperative glucose management compared to standard insulin therapy, across all assessed care periods and for both perioperative pathways (range 2.1-4.5). For a major abdominal surgery, total time required was 248.5 min using FCL versus 753.9 min using standard insulin therapy. For a minor abdominal surgery, total time required was 68.6 min and 133.2 min for FCL and standard insulin therapy, respectively. The use of fully automated closed-loop insulin delivery for inpatient glucose management has the potential to alleviate the workload of diabetes management in an environment with adequately trained staff.

A prospective study evaluating perioperative quality metrics of cancer surgery: Experience from a tertiary care cancer centre in India.

Well-defined quality metrics were studied at this high-volume tertiary care academic oncology centre to evaluate surgical quality and outcomes. A prospective cohort of 691 patients undergoing major surgeries for all cancers was observed between 1 September 2018 and 30 August 2019 and predefined quality indicators in three categories: namely, optimal hospital resource utilisation, quality of surgery and perioperative outcomes were recorded during their admission period. Surgical procedures were divided into group I versus group II involving simple/moderate complexity versus high complexity procedures for analysis done using appropriate tests in STATA v14.0. There were 373 versus 318 patients in group I versus group II with a mean of 48 years of age and 459 (66.43%) being females. Mean BMI was 24.58 kg/m2 , haemoglobin 12.12 g/dL and mean serum albumin of 4.25 g (SD ± 0.6). A total of 667(96.53%) patients had an Eastern Co-Operative Oncology Group performance score of 1 with 271 (39.22%) having comorbidities and 195 (28.22%) having tobacco/alcohol addictions. A total of 393 (56.87%) patients underwent prehabilitation. 83% of patients belonged to lower-middle socioeconomic status and 32% of patients had some prior surgical intervention. Neoadjuvant therapy was administered in 44.5% versus 37.42%, mean preoperative hospital stay was 3.65 versus 6.16 days whereas postoperative was 2.6 versus 6.09 days with total stay being 6.27 versus 12.21 days, mean surgical duration was 132 versus 268 min with mean blood loss of 100 versus 245 mL (group I vs. group II, respectively). Intraoperative events, namely, unexpected bleeding and hypotension occurred in 144 (20.84%) patients while packed red blood cells and/or fresh frozen plasma transfusion was required in 56 (8.1%) patients. 40% of patients needed intensive care unit care postoperatively with 45 (6.51%) patients having some event (hypotension, sepsis, acute kidney injury, etc.). A total of 29 (<4%) patients had ≥grade 3 surgical complications while ≥grade 2 medical complications occurred in 6.43% versus 12.58% of patients (group I vs. group II). A total of 90 (13.02%) patients were readmitted, 15 (2.17%) re-explored and 5 (0.72%) patients died. Optimal surgical outcomes in this study compared to international standards underpin the need for well-defined multidisciplinary perioperative pathways to be followed for each organ system and this framework can be adopted by other cancer centres in LMIC to achieve good surgical outcomes.

Validation of the Surgical Outcome Risk Tool (SORT) and SORT v2 for Predicting Postoperative Mortality in Patients with Pancreatic Cancer Undergoing Surgery.

Pancreatic cancer surgery is related to significant mortality, thus necessitating the accurate assessment of perioperative risk to enhance treatment decision making. A Surgical Outcome Risk Tool (SORT) and SORT v2 have been developed to provide enhanced risk stratification. Our aim was to validate the accuracy of SORT and SORT v2 in pancreatic cancer surgery. Two hundred and twelve patients were included and underwent pancreatic surgery for cancer. The surgeries were performed by a single surgical team in a single tertiary hospital (2016-2022). We assessed a total of four risk models: SORT, SORT v2, POSSUM (Physiology and Operative Severity Score for the enumeration of Mortality and Morbidity), and P-POSSUM (Portsmouth-POSSUM). The accuracy of the model was evaluated using an observed-to-expected (O:E) ratio and the area under the curve (AUC). The 30-day mortality rate was 3.3% (7 patients). Both SORT and SORT v2 demonstrated excellent discrimination traits (AUC: 0.98 and AUC: 0.98, respectively) and provided the best-performing calibration in the total analysis. However, both tools underestimated the 30-day mortality. Furthermore, both reported a high level of calibration and discrimination in the subgroup of patients undergoing pancreaticoduodenectomy, with previous ERCP, and CA19-9 ≥ 500 U/mL. SORT and SORT v2 are efficient risk-assessment tools that should be adopted in the perioperative pathway, shared decision-making (SDM) process, and counseling of patients with pancreatic cancer undergoing surgery.

Narcotic Requirements before and after Implementation of Buccal Nerve Blocks for Buccal Mucosa Graft Harvest: Technique and Retrospective Review

The reduction in opioid use has become a public health priority. We aimed to assess if performing buccal nerve blocks (BNB) at the time of buccal mucosa graft (BMG) harvest impacts post-operative narcotic usage in the inpatient setting. We retrospectively reviewed clinical characteristics and morphine milligram equivalents (MMEs) received for all patients that underwent a BMG urethroplasty at our institution. The primary outcome measure was post-operative MMEs for patients before and after implementing the BNB. We identified 74 patients that underwent BMG urethroplasty, 37 of which were before the implementation of the BNB and 37 of which were after. No other changes were made to the peri-operative pathway between these time points. The mean total MMEs per day, needed post-operatively, was lower in the BNB group (8.8 vs. 5.0, p = 0.12). A histogram distribution of the two groups, categorized by number of MMEs received, showed no significant differences between the two groups. In this retrospective analysis, we report our experience using BNBs at the time of buccal mucosa graft harvest. While there were no significant differences between the number of MMEs received before and after implementation, further research is needed to assess the blocks' impact on pain scores.

Postoperative Opioid Prescribing Following Outpatient Male Urethral Surgery: Evidence for Change.

Surgeons play a central role in the opioid epidemic. We aim to evaluate the efficacy of a standardized perioperative pain management pathway and postoperative opioid requirements in men undergoing outpatient anterior urethroplasty at our institution. Patients undergoing outpatient anterior urethroplasty by a single surgeon from August 2017 to January 2021 were prospectively followed. Standardized nonopioid pathways were implemented based on location (penile vs bulbar) and need for buccal mucosa graft. A practice change in October 2018 transitioned (1) from oxycodone to tramadol, a weak mu opioid receptor agonist, postoperatively and (2) from 0.25% bupivacaine to liposomal bupivacaine intraoperatively. Postoperative validated questionnaires included 72-hour pain level (Likert 0-10), pain management satisfaction (Likert 1-6), and opioid consumption. A total of 116 eligible men underwent outpatient anterior urethroplasty during the study period. One-third of patients did not use opioids postoperatively, and nearly 78% of patients used ≤5 tablets. The median number of unused tablets was 8 (IQR 5-10). The only predictor for use of >5 tablets was preoperative opioid use (75% vs 25%, P < .01). Overall, patients using tramadol postoperatively reported higher satisfaction (6 vs 5, P < .01) and greater percentages of pain reduction (80% vs 50%, P < .01) compared to those using oxycodone. For opioid-naïve men, 5 tablets or less of opioid medication with a nonopioid care pathway provides satisfactory pain control following outpatient urethral surgery without excessive overprescribing of narcotic medication. Overall, multimodal pain pathways and perioperative patient counseling should be optimized to further limit postoperative opioid prescribing.

Transplantation in paediatric patients with MMA requires multidisciplinary approach for achievement of good clinical outcomes

BackgroundAs modern medicine is advancing, younger, small, and more complex children are becoming multi-organ transplant candidates. This brings up new challenges in all aspects of their care.MethodsWe describe the first report of a small child receiving a simultaneous liver and kidney transplant and abdominal rectus sheath fascia transplant on the background of Williams syndrome and methylmalonic acidaemia. At the time of transplantation, the child was 3 years old, weighed 14.0 kg, had chronic kidney disease stage V, and had not yet started any other form of kidney replacement therapy.ResultsThere were many anaesthetic, medical, metabolic, and surgical challenges to consider in this case. A long general anaesthetic time increased the risk of cardiac complications and metabolic decompensation. Additionally, the small size of the patient and the organ size mis-match meant that primary abdominal closure was not possible. The patient’s recovery was further complicated by sepsis, transient CNI toxicity, and de novo DSAs.ConclusionsThrough a multidisciplinary approach between 9 specialties in 4 hospitals across England and Wales, and detailed pre-operative planning, a good outcome was achieved for this child. An hour by hour management protocol was drafted to facilitate transplant and included five domains: 1. management at the time of organ offer; 2. before the admission; 3. at admission and before theatre time; 4. intra-operative management; and 5. post-operative management in the first 24 h. Importantly, gaining a clear and in depth understanding of the metabolic state of the patient pre- and peri-operatively was crucial in avoiding metabolic decompensation. Furthermore, an abdominal rectus sheath fascia transplant was required to achieve abdominal closure, which to our knowledge, had never been done before for this indication. Using our experience of this complex case, as well as our experience in transplanting other children with MMA, and through a literature review, we propose a new perioperative management pathway for this complex cohort of transplant recipients.

Adolescent experiences of the safe surgical checklist and surgical care processes

To explore the perceptions, satisfaction, and needs of adolescent surgical patients with their perioperative pathway, including consent, the Safe Surgical Checklist (SSC), and post-operative care. We used qualitative methodology to examine adolescent experiences with surgical consent, SSC, and post-operative care. We purposively recruited ten patients aged 13-17 undergoing emergency and elective surgery and obtained consent from parents and patients. Semi-structured interview scripts were co-developed with an adolescent patient advisor, and interviews were performed, recorded, and transcribed verbatim. Thematic analysis was based on grounded theory and Participants were recruited and interviewed until thematic saturation was achieved. Four themes emerged in thematic analysis: (1) Autonomy and Inclusion-Adolescents desire to participate in the consent process, including signing their own consent when appropriate, (2) Value of Repetition-Adolescents value the repetition of information in the pre-operative check and feel safer when the team reinforces the information, (3) Importance of Caregiver Involvement - Adolescents valued their caregivers being involved in critical conversations and decision making, and (4) Importance of Transparency in Communication-Adolescents desire to be directly given information about their surgery post-operatively and not told to parents alone. Adolescents are situated uniquely between childhood and adulthood. Adolescents desired to be directly involved in the decision-making process of their surgery, including participation in the SSC and discussion of post-operative complications.

Enhanced recovery after surgery (ERAS) protocol in geriatric patients underwent unicompartmental knee arthroplasty: A retrospective cohort study.

The enhanced recovery after surgery (ERAS) pathway was formulated with the aim to reduce surgical stress response, alleviate pain and guarantee the best-fit experience of patients' perioperative period. However, the application of ERAS in geriatric patients who underwent unicompartmental knee arthroplasty (UKA) was relatively lacking. We hypothesize that UKA patients can benefit from the ERAS protocol. A total of 238 patients were recruited in this retrospective study from August 2018 to December 2021, and Oxford phase III UKA was applied to all patients. ERAS pathway included nutrition support, anesthesia mode, interoperative temperature, and blood pressure control, application of tranexamic acid, early initiation of oral intake and mobilization, and pain management. Demographic data, operation-relative variables, and postoperative complications were analyzed. Forgotten Joint Scores, Oxford Knee Score, Lysholm score, numerical rating scale, and knee range of motion were introduced to estimate the activity function and pain of surgical knee, and these variables were compared between the 2 groups. There were 117 patients in the ERAS group and 121 patients in the traditional group, respectively. The ERAS group had a shorter length of surgical incision and less intraoperative blood loss. Postoperative hemoglobin and albumin of patients in the ERAS group were better than those in the traditional group (P < .05), after 17.0 ± 10.8 months follow-up, the numerical rating scale, Lysholm, Oxford Knee Score, Forgotten Joint Scores, and knee range of motion of patients in the ERAS group were significantly better than the traditional group. The length of hospital stay for patients who underwent ERAS was 11.7 ± 3.8 days and the postoperative complication rate was lower for the ERAS group patients (P = .000 and 0.031). ERAS can reduce the length of hospital stay, and patients can achieve excellent postoperative knee function. The formulation and implementation of the ERAS protocol require good collaboration across multiple disciplines, as well as a deep understanding of the existing clinical evidence and the concept of the ERAS program.

Exploration and Practice of Medicine Pathway for Perioperative VTE Prophylactic Anticoagulant Treatment.

Using perioperative VTE prophylactic anticoagulant pathway delicacy management, we aimed to explore the role of clinical pharmacists in perioperative VTE prophylactic anticoagulant treatment and the effect of the clinical medicine pathway implementation. In compliance with evidence-based medicine, combined with clinical practice, clinical pharmacists participated in the formulation of the perioperative anticoagulant clinical medicine pathway. The PDCA cycle was strictly implemented. Urologic Department, Affiliated Hospital of Qingdao University, Qingdao Shandong, China, served as a pilot department for the evaluation of the effect of drug clinical pathway implementation. The anticoagulant clinical medicine pathway for the urologic department was formulated and implemented from October 2020 to August 2021. The entry rate gradually increased, and the accuracy of thrombosis risk assessment improved. The proportion of drugs in the department and the per capita drug cost decreased significantly. The perioperative VTE prophylactic anticoagulant pathway showed significant achievements in the rational use of urologic anticoagulant drugs, lowering the cost of medical care. Therefore, it could be considered a novel long-term mechanism for rational analgesia drug use.

Predictors of Gastrostomy Tube Placement in Head and Neck Cancer Patients at a Rural Tertiary Care Hospital

Abstract Background Head and neck cancer is a leading cause of cancer. Treatment often requires surgical resection, free-flap reconstruction, radiation, and/or chemotherapy. Tumor burden and pain may limit swallowing and impair nutrition, increasing complications and mortality. Patients commonly require gastrostomy tubes (G-tube), but predicting which patients are in need remains elusive. This study identifies predictors of G-tube among head and neck cancer patients undergoing immediate free-flap reconstruction. Methods Institutional Review Board approval was obtained. Retrospective database review was performed of patients at 18 years of age or older with head and neck cancer who underwent resection with immediate free-flap reconstruction from 2011 to 2019. Patients who underwent nonfree-flap or delayed reconstruction or with mortality within 7 days postoperatively were excluded. Patient demographics and comorbidities, tumor/treatment characteristics, and need for G-tube were analyzed to identify univariate and multivariate predictors. Results In total, 107 patients were included and 72 required G-tube placement. On multivariate analysis, tracheostomy (odds ratio [OR]: 81.78; confidence interval [CI]: 7.43–1,399.92; p &lt; 0.01), anterolateral thigh flap reconstruction (OR: 16.18; CI: 1.14–429.66; p = 0.04), and age 65 years or younger (OR: 9.35; CI: 1.47–89.11; p = 0.02) were predictors of G-tube placement. Conclusion Head and neck cancer treatment commonly involves extensive resection, reconstruction, and/or chemoradiation. These patients are at high risk for malnutrition and need G-tube. Determining who requires a pre- or postoperative G-tube remains a challenge. In this study, the need for tracheostomy or ALT flap reconstruction and age 65 years or younger were predictive of postoperative G-tube placement. Future research will guide a multidisciplinary perioperative pathway to facilitate the optimization of nutrition management.

Feasibility of Enhanced Recovery after Surgery in Pediatric Colostomy Reversal.

Enhanced recovery after surgery (ERAS) are multimodal perioperative pathways that have shown improved outcomes. ERAS after colostomy reversal has shown promising results in adults and few pediatric studies. We report our experience using ERAS for a colostomy reversal. A retrospective analysis of children in whom ERAS was used during colostomy reversal between May 2016 and 2019 was carried out. ERAS protocol in our study included avoiding mechanical bowel preparation (MBP), oral liquid diet upto 3 h preoperatively, usage of regional anesthesia, minimal handling of bowel intraoperatively, using nonopioid analgesics for pain relief, early initiation of feeding on the first postoperative day, early discharge once full feeds are established. Outcomes analyzed are the duration of hospital stay and complications, including readmissions. Requirement for opioids and anti-emetics are noted. The outcomes are compared with traditional care pathways (TCP), which use MBP, overnight fasting, opioid analgesia, and delayed feeding. A total of 48 are included in the study, with 13 cases using ERAS and TCP in 35 cases. Nonparametric Mann-Whitney U-test was used. In the ERAS group, the mean length of hospital stay (LOS) postoperatively was 3.7 days (2-5 days) as opposed to 7.2 days (5-11 days) in TCP. There was only one child with complications in the ERAS group, while 9 cases in TCP had complications, though none of them required operative intervention. There was the requirement of anti-emetic in only one child in the ERAS group. ERAS for colostomy reversal is feasible in the pediatric population. For successful implementation, all personnel involved in the care of the child need to be educated about the protocol. It reduces LOS and complications.

The impact of a postoperative multimodal analgesia pathway on opioid use and outcomes after cardiothoracic surgery

ObjectiveThe Enhanced Recovery after Surgery Cardiac Society recommends using multimodal analgesia (MMA) for postoperative pain however, evidence-based guidelines have yet to be established. This study examines the impact of a standardized postoperative MMA pathway in reducing opioid consumption and related complications after cardiothoracic surgery (CTS).MethodsWithin a multicenter healthcare system, a postoperative MMA pathway was developed and implemented at two CTS intensive care units (ICU) while the other CTS ICU opted to maintain the existing opioid-based pathway. A retrospective chart review was conducted on patients admitted to a CTS ICU within this healthcare system after conventional coronary artery bypass grafting and/or valve surgery from September 1, 2018, to June 30, 2019. Comparative analysis was conducted on patients prescribed MMA versus those managed with an opioid-based pathway. The primary outcome was total opioid consumption, converted to morphine milligram equivalents, 72-h post-surgery. Secondary outcomes included mobility within one-day post-surgery, ICU length of stay (LOS), time to first bowel movement (BM), and time to first zero Richmond Agitation-Sedation Scale (RASS).ResultsSeven hundred sixty-two adults were included for final analysis. The MMA group had a higher body mass index, higher percentage of females, were more likely classified as African American and had higher scores for risk-adjusted complications. General Linear Model analysis revealed higher opioid consumption in the MMA group (Est. 0.22, p < 0.0009); however, this was not statistically significant after adjusting for differences in fentanyl usage. The MMA group was more likely to have mobility within one-day post-surgery (OR 0.44, p < 0.0001), have longer time to first BM (OR 1.93, p = 0.0011), and longer time to first zero RASS (OR 1.62, p = 0.0071). The analgesia groups were not a predictor for ICU LOS.ConclusionsOpioid consumption was not reduced secondary to this postoperative MMA pathway. The MMA group was more likely to have mobility within one-day post-surgery. Patients in the MMA group were also more likely to have prolonged time to first BM and first zero RASS. Development and evaluation of a perioperative MMA pathway should be considered.

Effect of a Personalized Enteral Nutrition Protocol on the Postoperative Nutritional Status in Patients Who Underwent Oral Cancer Surgery

Differences in the implementation of the perioperative nutrition guidelines and pathways by caregivers lead to differences in enteral nutrition provided to the patients. This study investigated the effect of a personalized enteral nutrition protocol on the postoperative nutritional status of patients who underwent oral cancer surgery at Zhejiang Ningbo NO. 2 Hospital. Those who underwent surgery between July 2017 and October 2018 received routine enteral nutrition based on the Nutritional Risk Screening 2002 (routine group), while those between November 2018 and August 2021 received personalized enteral nutrition based on the Patient-Generated Subjective Global Assessment tool (personalized group). Seventy patients completed the study (routine group, n = 34; personalized group, n = 36). After surgery, the personalized group exhibited significantly greater improvements in serum albumin levels (P < 0.01) (on the 7th and 10th day) and hand grip strength (P < 0.01), higher self-care ability (P < 0.01), lower incidence of gastrointestinal reactions during enteral feeding (P < 0.05), and shorter hospital stay (P < 0.05) than the routine group. Therefore, a personalized enteral nutrition program might improve the postoperative nutritional status, shorten the hospital stay, and accelerate postoperative recovery in patients who underwent oral cancer surgery.

OGC P09 Optimising the management of perioperative anaemia in patients with oesophagogastric cancer

Abstract Background Patients with oesophagogastric malignancy are predisposed to anaemia due to iron deficiency from chronic luminal blood loss. In the pre and post-operative periods, anaemia is associated with increased morbidity and mortality, principally through an increased blood transfusion (BTF) requirement. Anaemia of iron deficiency can be treated with oral or parenteral iron therapy. Newer preparations of parenteral iron therapy have lower rates of complications and are increasingly available. This study explored the effects of an anaemia management pathway on the detection and treatment of perioperative anaemia, as well as the post-operative course of patients undergoing staging and surgical resection of oesophagogastric malignancy. The impact of different forms of iron therapy was also examined. Methods A retrospective analysis was performed of patients undergoing resection of oesophageal, oesophagogastric or gastric malignancies between 12/11/2014 and 31/12/2021 at a tertiary oesophagogastric malignancy centre. A structured pathway for the management of perioperative anaemia was introduced on 1/4/2019 and patients were split into those receiving treatment on the anaemia management pathway compared to historical controls receiving standard treatment before this point. Clinicopathological variables were recorded from the hospital system tracking the haemoglobin (Hb) from diagnosis, through to the day of surgery and in the postoperative period. Other variables identified included iron therapy in the pre or postoperative period, blood transfusion rates, length of stay data and survival as of 01/03/2022. Anaemia was defined using both strict anaemia (Hb &amp;lt; 100g/L) and WHO anaemia (Hb &amp;lt; 120g/L for females and Hb &amp;lt; 130g/L for males) criteria. All analyses and statistical tests were conducted using R software. Results There were 171 patients treated under the new anaemia management pathway, and 343 historical controls receiving standard management. The overall prevalence of anaemia at the point of diagnosis was 33.7% using WHO criteria. Anaemia was more prevalent in patients with gastric malignancies (49%) than those with oesophageal malignancies (19%, p= 0.008) or OGJ malignancies (32%, p=0.017). Following the introduction of the anaemia management pathway, the blood transfusion (BTF) rates and the average length of stay did not change. The proportion of patients with WHO defined anaemia receiving IV iron therapy increased from 0.3% to 18% in the pre-operative period (p &amp;lt; 0.001), and from 2% to 39% in the post-operative period (p &amp;lt; 0.001). In the postoperative period, in-patient IV iron was more effective than oral (p &amp;lt; 0.001) or no iron treatment (p &amp;lt; 0.001) in improving haemoglobin post-operatively at a 6-week follow-up. Conclusions Anaemia is common in patients with oesophagogastric malignancy and patients with gastric cancer were more likely to be anaemic than other patient groups. The introduction of a perioperative anaemia management pathway can improve the use of iron therapy for anaemic patients, but we did not detect a difference in postoperative blood transfusions. IV iron treatment is significantly better than oral or no iron treatment in improving postoperative haemoglobin. IV iron should therefore be incorporated into post-operative management guidelines for post-operative anaemia and used preferentially to oral iron. Further studies should look to prospectively characterise the impacts of iron treatment and explore further variables such as quality of life in the postoperative period.
