RESUMEN
BACKGROUND: To optimize the postoperative phase following bariatric surgery, the enhanced recovery after bariatric surgery pathway (ERABS) has been developed. The aim of ERABS is to create a care path that is as safe, efficient and patient-friendly as possible. Continuous evaluation and optimization of ERABS are important to ensure a safe treatment path and may result in better outcomes. The objective of this study was to compare the clinical outcomes of patients undergoing bariatric surgery over 2014-2017, during which the ERABS protocol was continuously evaluated and optimized. METHODS: This is a retrospective cohort study. Data were collected from patients undergoing a primary Roux-en-Y gastric bypass or sleeve gastrectomy between January 2014 and December 2017. Outcomes were early complications, unplanned hospital revisits, readmissions, duration of surgery and length of hospital stay. RESULTS: 2889 patients underwent a primary bariatric procedure in a single center. There was a significant decrease in minor complications over the years from 7.0 to 1.9% (p < 0.001). Hospital revisit rates decreased after 2015 (p < 0.001). Readmission rates decreased over time (p < 0.001). The mean duration of surgery decreased from 52 (in 2014) to 41 (in 2017) minutes (p < 0.001). Median length of hospital stay decreased from 1.8 to 1.5 days in 2015 (p = 0.002) and remained stable since. CONCLUSION: An improvement of the ERABS protocol was associated with a decrease in minor complication rates, number of unplanned hospital revisits and readmission rates after primary bariatric procedures.

BACKGROUND: For metabolic laparoscopic surgery, higher pressures up to 20 mmHg are often used to create a surgical field of sufficient quality. This randomized pilot study aimed to determine the feasibility, safety and tolerability of low intraabdominal pressure (IAP) and deep neuromuscular blockade (NMB) to reduce postoperative pain. METHODS: In a teaching hospital in the Netherlands, 62 patients eligible for a laparoscopic Roux-en-Y gastric bypass (LRYGB) were randomized into one of four groups in a 2 × 2 factorial design: deep/moderate NMB and standard (20 mmHg)/low IAP (12 mmHg). Patient and surgical team were blinded. Primary outcome measure was the surgical field quality, scored on the Leiden-Surgical Rating Scale (L-SRS). Secondary outcome measures were (serious) adverse events, duration of surgery and postoperative pain. RESULTS: 62 patients were included. L-SRS was good or perfect in all patients that were operated under standard IAP with deep or moderate NMB. In 40% of patients with low IAP and deep NMB, an increase in IAP was needed to improve surgical overview. In patients with low IAP and moderate NMB, IAP was increased to improve surgical overview in 40%, and in 75% of these cases a deep NMB was requested to further improve the surgical overview. Median duration of surgery was 38 min (IQR34-40 min) in the group with standard IAP and moderate NMB and 52 min (IQR46-55 min) in the group with low IAP and deep NMB. CONCLUSIONS: The combination of moderate NMB and low IAP can create insufficient surgical overview. Larger trials are needed to corroborate the findings of this study.

Patients with class II and III obesity and end-stage renal disease are often ineligible for kidney transplantation (KTx) due to increased postoperative complications and technically challenging surgery. Bariatric surgery (BS) can be an effective solution for KTx candidates who are considered inoperable. The aim of this study is to evaluate outcomes of KTx after BS and to compare the outcomes to obese recipients (BMI ≥ 35 kg/m2 ) without BS. This retrospective, single-center study included patients who received KTx after BS between January 1994 and December 2018. The primary outcome was postoperative complications. The secondary outcomes were graft and patient survival. In total, 156 patients were included, of whom 23 underwent BS prior to KTx. There were no significant differences in postoperative complications. After a median follow-up of 5.1 years, death-censored graft survival, uncensored graft survival, and patient survival were similar to controls (log rank test p = .845, .659, and .704, respectively). Dialysis pre-transplantation (Hazard Ratio (HR) 2.55; 95%CI 1.03-6.34, p = .043) and diabetes (HR 2.41; 95%CI 1.11-5.22, p = .027) were independent risk factors for all-cause mortality. A kidney from a deceased donor was an independent risk factor for death-censored graft loss (HR 1.98; 95%CI 1.04-3.79, p = .038). Patients who received a KTx after BS have similar outcomes as obese transplant recipients.

INTRODUCTION: Fast-track protocols often include short-term thromboprophylaxis and short length of hospital stay. These treatment strategies may negatively affect the occurrence and diagnosis of postoperative haemorrhage. Over the years, the rates of venous thromboembolic events (VTEs) have decreased, while there seems to be an increase in the occurrence of postoperative haemorrhage. Tranexamic acid (TXA) can potentially lower the incidence of postoperative haemorrhage. This trial aims to investigate whether preoperative administration of TXA reduces the preoperative and postoperative haemorrhage rates in laparoscopic sleeve gastrectomy (LSG). METHODS AND ANALYSIS: This is a single centre double-blind randomised placebo-controlled trial. Patients undergoing an LSG are included after obtaining informed consent. Patients are randomised between two groups: (1) administration of placebo infusion and (2) administration of 1500 mg TXA. In both groups, the infusions will be administered during the induction phase of the procedure. Primary outcome measures are preoperative use of haemostatic clips, postoperative haemoglobin decrease and postoperative haemorrhage. Secondary outcome measure is the rates of VTE. ETHICS AND DISSEMINATION: The protocol version 3 was approved by the medical ethical committee Medical Research Ethics Committees United (MEC-U), Nieuwegein, on 29 July 2019. The trial results will be submitted for publication in a peer-reviewed journal and at conference presentations. TRIAL REGISTRATION NUMBER: The Netherlands Trial Registry (NL8029); Pre-results.

BACKGROUND: Obesity is a major risk factor for cardiovascular disease. Data on structural and functional arterial changes after bariatric surgery are scarce. OBJECTIVES: The aim of this study was to determine the effects of bariatric surgery on the carotid intima media thickness (cIMT) and pulse wave velocity (PWV). SETTING: General hospital. METHODS: We collected data prospectively in 200 patients scheduled for bariatric surgery between 2015-2017. Based on an increase or decrease of 1 standard deviation of the mean difference in cIMT and PWV 1 year postoperatively, patients were divided into progressors, regressors', and unchanged. We analyzed data on medical history, baseline body mass index, surgery type, and difference in body mass index after 1 year. RESULTS: Data on cIMT were available for 134 patients. Thirty-four patients (25.4%) had a cIMT regression with a mean decrease of .1 mm (-.24 to -.06), 10 patients (7.5%) were progressors with a mean increase of .1 mm (.07-.30), and 90 patients (67.2%) remained unchanged. Progressors more often had type 2 diabetes (P = .035) and hypertension (P = .020). Data on PWV were available for 120 patients, of whom 91 (75.8%) were regressors, 26 (21.6%) remained unchanged, and 3 (2.5%) were progressors. Predictors of PWV changes were total plasma cholesterol and hypertension at baseline. CONCLUSIONS: A significant improvement of the vascular quality already after 1 year of follow-up was established in 25%-76% of all patients after bariatric surgery and the vast majority showed stabilization.

Intravesical administration of bacille Calmette-Guérin (BCG) is considered to be the therapy of choice for treating superficial bladder carcinoma. Created from a live attenuated strain of Mycobacterium bovis, BCG is theoretically unable to cause infections. However, both local and systemic complications due to infection are known to arise, including vascular complications. We describe the case of a patient with a history of BCG instillations presenting with an arterial rupture of his left iliac artery due to an abscess in the iliopsoas muscle.
