Patient and operative factors influence delayed discharge following bariatric surgery in an enhanced recovery setting

BACKGROUND

Enhanced Recovery After Surgery (ERAS) programs have been widely adopted in bariatric surgery. However, not all patients are successfully managed in the ERAS setting and there is currently little way of predicting the patients who will deviate from the program. Early identification of these patients could allow for more tailored protocols to be implemented preoperatively to address the issues, thereby improving patient outcomes.

OBJECTIVES

The aim of this study was to elucidate the factors which preclude discharge by comparing patients who were successfully discharged by the end of the first postoperative day (POD 0/1) to those who stayed longer, including revisional surgery in this analysis.

SETTING

A tertiary, high-volume Bariatric Centre, United Kingdom.

METHODS

A retrospective analysis was performed of all patients undergoing bariatric surgery in a single centre in 1 year. Multivariate analyses compared patient and operative variables between patients who were discharged on POD 0/1 and those who stayed longer.

RESULTS

A total of 288 bariatric operations were performed: 78% of operations performed were laparoscopic Roux-en-Y gastric bypass; 22% laparoscopic sleeve gastrectomy. Of these cases, 13% were revisional operations. Four patients returned to theatre on the index admission. 81% of patients were discharged by POD 0/1. A re-presentation within 30 days was seen in 6% of patients. There was no significant difference in length of stay for the type of operation performed (P = .86). Patients who had a revisional procedure were not more likely to stay longer. Length of stay was also independent of age, BMI, and comorbidities. Caucasian patients were more likely to be discharged on POD 0/1 than those of other ethnicities (90% versus 78%; P = .02). Operations performed by trainee surgeons, under consultant supervision, were significantly more likely to be discharged on POD 0/1 (P = .03). However, a logistic regression analysis was unable to predict patients who had a prolonged stay.

CONCLUSIONS

Patient length of stay is independent of BMI, operation, and comorbidities and these factors do not need special consideration in ERAS pathways. Patients undergoing revisional procedures can be managed in the same way as those having primary procedures, with a routine POD 0/1 discharge. However, the impact of individual patient factors, and their interaction, is complex and cannot predict overstay.

Assessment of obesity

Obesity is a chronic, progressive and relapsing disease, characterised by the presence of abnormal or excess adiposity that impairs health and social wellbeing. It is associated with obesity-related disease complications, health inequalities and premature death. Clinical evaluation of obesity requires a thorough history and examination. Assessment should focus not only on anthropometric measurements, but also on the mental, metabolic, mechanical and monetary impact of adiposity, including multiple health conditions. Increased awareness and knowledge will help reduce weight stigma and biases. A focused non-judgemental assessment will help guide further investigations, timely referral and management.

BS P02 Sleeve gastrectomy and gastric bypass day surgery: outcomes and experience from a single centre

Background

Internationally, day case Bariatric surgery has been shown to be safe, feasible and economically beneficial. However, it has not been widely adopted in the UK. It requires careful patient selection and a mature enhanced recovery programme. We report on the outcomes and lessons learned during our 2.5-year experience of day case laparoscopic sleeve gastrectomies (LSG) and Roux-en-y gastric bypass (RYGB) operations.

Methods

A retrospective analysis was performed of all patients who were selected as candidates for day case Bariatric surgery in a single-centre since October 2019. Patients were considered eligible if they had a BMI <60, lived within 30 minutes of the hospital, were having primary surgery with no additional procedure and were not on CPAP. All patients received a nurse-led telephone assessment on day 1. Rates of successful discharge, patient demographics, readmission and outcomes were analysed.

Results

Thirty-nine patients were identified as suitable candidates for day case operations: 24 (62%) RYGB, 15 (38%) LSG. The mean BMI was 46.5; 85% female. The main reason for not being considered was the patient living >30 minutes away. Overall, 18 (13 RYGB, 5 LSG; 46.2%) were successfully discharged on the day of surgery. Fifteen (38.5%) were discharged on the first post-operative day and 6 (15.4%) stayed two or more days. The commonest reasons for failed discharge were nausea/vomiting 6 (15.4%) and logistical issues e.g. operation in the afternoon 6 (15.4%). There was one readmission within 30 days (sealed leak from the gastro-jejunal anastomosis) but no returns to theatre.

Conclusions

We have successfully performed day case Bariatric surgery in our centre. However, it is a logistical challenge and to date has only been carried out successfully on a small number of patients. The main challenge being the vast catchment area for our tertiary centre. Further work is needed to better define the parameters for patient eligibility in order to safely offer this to more patients.

Managing obesity in people with type 2 diabetes

Obesity is a modifiable risk factor in the development of type 2 diabetes mellitus (T2DM), with the prevalence of both increasing worldwide. This trend is associated with increasing mortality, cardiovascular risk and healthcare costs. An individual's weight will be determined by complex physiological, psychological and societal factors. Assessment by a skilled multidisciplinary team will help identify these factors and will also support screening for secondary causes, assessing cardiovascular risk and identifying sequelae of obesity.A range of treatment options are available for people with obesity and T2DM, including low-calorie diets, medications and bariatric surgery. People should be carefully counselled and personalised care plans developed. Bariatric surgery is an under-utilised resource in this context.Obesity should also be considered when choosing medical therapy for T2DM. Common diabetes medications may lead to weight gain whereas others (such as glucagon-like peptide-1 agonists and sodium-glucose cotransporter-2 inhibitors) support weight loss.Bariatric surgery improves obesity-related complications and all-cause mortality. Diabetes remission is possible after surgery and is recommended by National Institute for Health and Care Excellence in individuals with a body mass index of >35 kg/m² and recent onset T2DM.

Bariatric surgery in individuals with human immunodeficiency virus and type 2 diabetes: a case series

Background

The efficacy and safety of bariatric surgery have not been fully elucidated in patients affected with human immunodeficiency virus. Although adjustable gastric banding and sleeve gastrectomy are starting to be used in patients with human immunodeficiency virus, there are limited descriptions of the outcomes of type 2 diabetes mellitus in individuals who are human immunodeficiency virus positive and undergoing these procedures.

Case presentation

We have evaluated retrospectively three patients who underwent adjustable gastric banding or sleeve gastrectomy, the effect in weight reduction and glycemic control as well as its impact on human immunodeficiency virus management. Case 1 (adjustable gastric banding), a 58-year-old Caucasian male, achieved 19% total weight loss, Case 2, a 33-year-old Caucasian male (sleeve gastrectomy) lost 25%, and Case 3, a 48-year-old Caucasian female (sleeve gastrectomy), lost 14% postoperation. In terms of type 2 diabetes mellitus, Case 2 achieved complete remission according to American Diabetes Association criteria, while Case 1 would also have achieved remission were it not for the continuation of metformin postoperatively. Insulin requirements and pill burden were markedly reduced in Case 3 after sleeve gastrectomy, although lack of remission was predictable given the longevity of type 2 diabetes mellitus and preoperative insulin dosage. In all three cases, human immunodeficiency virus status did not appear to be affected by the bariatric surgery which was supported by the postoperative stable CD4 count and undetectable viral load.

Conclusions

Bariatric surgery is a safe and effective treatment modality in patients who are human immunodeficiency virus positive with obesity and type 2 diabetes mellitus.

The Challenges of Conducting Research on the Acute Medical Unit

Conducting research on the Acute Medical Unit (AMU) poses unique challenges; the environment is one that sees a diverse range of patient groups and pathologies and holds the potential for easy patient recruitment to research studies, however is geared towards a specific set of triage and discharge goals. We conducted a study into Stress Hyperglycaemia (SH) on a busy AMU, which involved profiling glycaemic changes using specialist equipment and interventions in patients with unscheduled medical admissions, and experienced a number of challenges. This article discusses these challenges and proposes potential solutions. Conducting research on a busy AMU was complicated by factors including rapid patient and staff turnover, the differing goals of the AMU system and suboptimal staff engagement in labour intensive research. We endeavored to follow patients up in further visits after discharge but found they lacked engagement after the resolution of the acute illness requiring initial admission. In this article, we discuss these issues in more detail and suggest approaches for future AMU researchers.

Meningococcal antigen in diagnosis and treatment of group A meningococcal infections

Meningococcal antigen was measured by countercurrent immunoelectrophoresis in the blood and cerebrospinal fluid of 200 patients with group A meningococcal meningitis. Antigen was detected in the blood of 27 (13.5 per cent) patients. These patients had a worse prognosis and a higher incidence of allergic complications, such as arthritis and vasculitis, about 5 days after the start of antibiotic treatment. Antigen was found in the CSF of 129 (67.5 per cent) patients); antigen often persisted in the cerebrospinal fluid despite antibiotic treatment before admission. A combination of immunoelectrophoresis and routine bacteriologic study was used in the diagnosis of 162 (84.8 per cent) patients with meningococcal meningitis. High levels of antigen and a slow antigen disappearance were associated with neurologic damage. The antigen is stable and may be detected from specimens of cerebrospinal fluid dried on filter paper.

Primary neuropathic amyloidosis in three brothers

Neuropathic primary amyloidosis has not been previously described in an English family. We present the clinical and pathological findings in three brothers with this condition and suggest that they have suffered from that form of the disease described originally by Andrade.

Trial of chloramphenicol for meningitis in northern savanna of Africa

In a controlled trial chloramphenicol proved as effective and much cheaper than penicillin for the treatment of group A meningococcal meningitis in Zaria, Nigeria. A short course of five days cured most patients. Adults and older children were soon able to take chloramphenicol by mouth, which reduced the cost and simplified treatment.It is suggested that chloramphenicol is a suitable alternative to sulphonamides for the treatment of meningococcal meningitis in those parts of Africa where the organism is sulphonamide-resistant.
