Fast track bariatric surgery: safety of discharge on the first postoperative day after bariatric surgery

Safety and factors associated with early discharge in revisional laparoscopic Roux-en-Y gastric bypass: analysis of the MBSAQIP database

BACKGROUND

Improvements in bariatric surgery outcomes have prompted policy initiatives that explore shifting bariatric surgery toward outpatient procedures. While the safety of early discharge after primary laparoscopic Roux-en-Y gastric bypass (LRYGB) has been reported, its safety for revisional LRYGB remains uncertain. Our study aimed to investigate the safety and patient factors associated with early discharge in patients undergoing revisional LRYGB compared with primary LRYGB.

METHODS

We identified adult patients who underwent primary and revisional LRYGB from 2020 to 2022 in the MBSAQIP database. Patients discharged early, i.e., same-day discharge (SDD) and next-day discharge (NDD) were compared to inpatients. Outcomes included 30-day complications (minor = Clavien-Dindo 1-2; major = Clavien-Dindo 3-4), mortality, readmissions, and reoperations. Multivariable logistic regression models adjusting for patient demographics, comorbidities, and operative time were fitted to assess the study outcomes.

RESULTS

SDD rate was similar after primary (3,422/137,406; 2.5%) and revisional LRYGB (781/32,721; 2.4%), while NDD rate was higher in primary LRYGB (59.8% vs 54.7%, respectively; p < 0.001). SDD patients had lower odds of major complications compared to inpatients following primary (2% vs 7%, aOR: 0.30, 95%CI 0.24-0.38) and revisional LRYGB (3.7% vs 9.3%, aOR: 0.43, 95%CI 0.29-0.62, respectively). NDD patients had similarly lower odds of morbidity outcomes. ASA Classification IV/V was associated with lower odds of SDD compared to Class I/II (Primary: 0.9% vs. 3%, aOR: 0.61, 95% CI 0.48-0.78; Revisions: 0.9% vs. 3%, aOR: 0.24, 95%CI 0.10-0.55).

CONCLUSION

Early discharge after revisional LRYGB, particularly after an overnight stay, can be accomplished safely in carefully selected patients. However, SDD rates remain low limiting its safety assessment. Further, almost half of the patients stay more than 48 h in the hospital suggesting that policy initiatives toward outpatient management after bariatric surgery may be inappropriate for this patient population.

Outcomes of same-day discharge in bariatric surgery

BACKGROUND

Restrictions during the COVID-19 pandemic influenced a shift to same-day discharge in bariatric surgery. Current studies show conflicting findings regarding morbidity and mortality. We aim to compare outcomes for same-day discharge versus admission after bariatric surgery.

METHODS

Subjects included patients who underwent primary laparoscopic or robotic-assisted sleeve gastrectomy or Roux-En-Y gastric bypass at an academic center. The inpatient group included patients discharged postoperative day one, and the outpatient group included patients discharged on the day of surgery. Primary outcomes included the number of emergency room visits, reoperations, IV fluid treatments, readmissions, and mortality within 30 days. Secondary outcomes were morbidity, including skin and soft tissue infection, pulmonary embolism, and acute kidney injury.

RESULTS

1225 patients met the inclusion criteria. In the gastric sleeve group, 852 subjects were outpatients and 227 inpatients. In the gastric bypass group, 70 subjects were outpatients, and 40 were inpatients. The mean age was 44.63 (17.38-85.31) years, and the mean preoperative BMI was 46.07 ± 8.14 kg/m2. The subjects in the outpatient group had lower BMI with fewer comorbidities. The groups differed significantly in age, BMI, and presence of several chronic comorbidities. The inpatient and outpatient groups for each surgery type did not differ significantly regarding reoperations, IV fluid treatments, or 30-day mortality. The inpatient sleeve group demonstrated a significantly higher readmission percentage than the outpatient group (4.6% vs 2.1%; p = 0.02882). The inpatient bypass group showed significantly greater ER visits (21.7% vs 10%; p = 0.0108). The incidence of adverse events regarding the secondary outcomes was not statistically different.

CONCLUSION

Same-day discharge after bariatric surgery is a safe and reasonable option for patients with few comorbidities.

Ambulatory bariatric surgery: a prospective single-center experience

BACKGROUND

Ambulatory bariatric surgery has recently gained interest especially as a potential way to improve access for eligible patients with severe obesity. Building on our previously published research, this follow-up study delves deeper in the evolving landscape of ambulatory bariatric surgery over a 3-year period, focusing on predictors of success/failure.

METHODS

In a prospective single-center follow-up study, we conducted a descriptive assessment of all eligible patients as per our established protocol, who underwent a planned same-day discharge (SDD) primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 03/01/2021 and 02/29/2024. Trends in SDD surgeries over time were assessed over six discrete 6 month intervals. Primary endpoint was defined as a successful discharge on the day of surgery without emergency department visit or readmission within 24 h. Secondary outcomes included 30-day postoperative morbidity.

RESULTS

A total of 811 primary SG and 325 RYGB procedures were performed during the study period. Among them, 30% (n = 244) were SDD-SGs and 6% (n = 21) were SDD-RYGBs, respectively. At baseline, median age of the entire SDD cohort was 43 years old, 81% were females, and body mass index (BMI) was 44.5 kg/m2. The planned SDD approach was successful in 89% after SG (n = 218/244) and in 90% after RYGB (n = 19/21). Nausea/vomiting was the main reason for a failed SDD approach after SG (46%). The 30-day readmission rate was 1.5% (n = 4) for the entire SDD cohort including only one readmission in the first 24 h. The percentage of SDD-SGs performed as a proportion of total SGs increased over the initial five consecutive six-month intervals (14%, 25%, 24%, 38%, and 49%).

CONCLUSION

Our SDD protocol for bariatric surgery demonstrates a favorable safety profile, marked by high success rate and low postoperative morbidity. These outcomes have led to a continued increase in ambulatory procedures performed over time especially SG.

Patient Satisfaction and Experience with Same-Day Discharge After Laparoscopic Roux-en-Y Gastric Bypass: A Mixed-Methods study

INTRODUCTION

Same-day discharge (SDD) after laparoscopic Roux-en-Y gastric bypass (RYGB) is a safe and effective healthcare pathway. However, there is limited understanding of the patient perspective on SDD. The aim of this study was to explore patient satisfaction and experience with SDD after RYGB.

METHODS

A mixed-methods study with a concurrent design was conducted in a Dutch teaching hospital, using questionnaires and interviews. Patients who underwent RYGB and were discharged on the day of the surgery completed four questionnaires of the BODY-Q (satisfaction with the surgeon, satisfaction with the medical team, satisfaction with the office staff, and satisfaction with information provision) ± 4 months postoperative. The results of the questionnaires were compared with pre-existing data from a cohort of patients who stayed overnight after surgery (i.e., control group). A subset of patients was individually interviewed for an in-depth understanding of the patient perspective on SDD.

RESULTS

In the questionnaires, median scores for the control group (n = 158) versus the present group of patients (n = 51) were as follows: 92/100 vs. 92/100 (p = 0.331) for the surgeon, 100/100 vs. 92/100 (p = 0.775) for the medical team, 100/100 vs. 100/100 (p = 0.616) for the office staff, and 90/100 vs. 73/100 (p = 0.015) for information provision. Interviews with 14 patients revealed seven themes, describing high satisfaction, along with several points of interest.

CONCLUSIONS

Patient satisfaction with SDD after RYGB is high, although information provision regarding the day of surgery could be improved. However, not every medically eligible patient might be suitable for this healthcare pathway, as responsibilities are shifted.

Periprocedural Changes of Serum Biomarkers in Predicting Complications Following Bariatric Surgery for Obesity: Systematic Review and Meta-analysis

Bariatric surgery is an effective treatment for severe obesity, but complications and peri-operative monitoring are important considerations. We conducted a comprehensive review of studies assessing pre-operative biomarkers and complications in patients undergoing bariatric surgery. A total of 14 studies were included. Gastric leak, infections, bleeding, obstruction or stenosis, hypoglycemia, and hypoalbuminemia were the most common complications observed. Our analysis showed a significant association between lower pre-operative albumin levels and complications (SMD [95%CI] =  - 0.21 [- 0.38; - 0.04]). However, other biomarkers did not have a significant impact on complication occurrence. Changes in C-reactive protein, neutrophil-lymphocyte ratio, and white blood cell levels were observed in certain peri-operative time points and complication subgroups. These findings suggest the potential use of pre-operative biomarkers and peri-operative changes of biomarker's levels for predicting complications.

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.

Evaluating the Impact of Enhanced Recovery After Surgery Protocols on Surgical Outcomes Following Bariatric Surgery-A Systematic Review and Meta-analysis of Randomised Clinical Trials

BACKGROUND

Enhanced recovery after surgery (ERAS) programmes are evidence-based care improvement processes for surgical patients, which are designed to decrease the impact the anticipated negative physiological cascades following surgery.

AIM

To perform a systematic review and meta-analysis of randomised clinical trials (RCTs) to evaluate the impact of ERAS protocols on outcomes following bariatric surgery compared to standard care (SC).

METHODS

A systematic review was performed in accordance with PRISMA guidelines. Meta-analysis was performed using Review Manager version 5.4 RESULTS: Six RCTs including 740 patients were included. The mean age was 40.2 years, and mean body mass index was 44.1 kg/m2. Overall, 54.1% underwent Roux-en-Y gastric bypass surgery (400/740) and 45.9% sleeve gastrectomy (340/700). Overall, patients randomised to ERAS programmes had a significant reduction in nausea and vomiting (odds ratio (OR): 0.42, 95% confidence interval (CI): 0.19-0.95, P = 0.040), intraoperative time (mean difference (MD): 5.40, 95% CI: 3.05-7.77, P < 0.001), time to mobilisation (MD: - 7.78, 95% CI: - 5.46 to - 2.10, P < 0.001), intensive care unit stay (ICUS) (MD: 0.70, 95% CI: 0.13-1.27, P = 0.020), total hospital stay (THS) (MD: - 0.42, 95% CI: - 0.69 to - 0.16, P = 0.002), and functional hospital stay (FHS) (MD: - 0.60, 95% CI: - 0.98 to - 0.22, P = 0.002) compared to those who received SC.

CONCLUSION

ERAS programmes reduce postoperative nausea and vomiting, intraoperative time, time to mobilisation, ICUS, THS, and FHS compared to those who received SC. Accordingly, ERAS should be implemented, where feasible, for patients indicated to undergo bariatric surgery.

Shifting paradigms: protocol implementation to reduce length of stay for bariatric surgery following the pandemic at a high volume bariatric center

BACKGROUND

With the Covid-19 pandemic reducing the capacity to perform elective bariatric surgical cases, a multidisciplinary approach to reducing length of stay has been essential to continue providing this service. In conjunction with the use of our local ERAS protocols, same day discharge (SDD) and early next day discharge (NDD) for bariatric surgery is becoming more of a reality.

OBJECTIVES

To evaluate the effectiveness of our new protocols targeted at reducing length of stay (LOS) for our bariatric surgery patients during the pandemic. Secondary outcomes included comparisons of readmission and complications compared to baseline data.

METHODS

The MBSAQIP data set was analyzed identifying patients who underwent laparoscopic roux-en- Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (SG) from April to November 2021. Mean LOS and complication rates including re-admission in this baseline group were documented. This was compared to a cohort who underwent the surgeries between December 2021 and February 2022 under our new protocols for early discharge.

RESULTS

195 patients underwent bariatric surgery in the baseline group and 87 patients in the early discharge cohort were included. There was a statistically significant decrease in mean LOS comparing baseline group (34.5 h) and next day PACU discharges (25 h) with P = 0.004. No increase in complication rate from the early discharge cohort against the baseline group. (P = 0.014).

CONCLUSION

SDD and NDD in carefully selected bariatric surgery patients is feasible with good outcomes. With ERAS protocols as a foundation and a multidisciplinary approach, this can be achieved in spite of pressures placed on bariatric units by the pandemic.

Implementation of a same-day discharge bariatric surgery program and follow-up with a telemonitoring platform

INTRODUCTION

Some groups have initiated outpatient bariatric surgery programs in selected patients, publishing good results after sleeve gastrectomy. Recent studies show that outpatient surgery is also feasible and safe in Roux-en-Y gastric bypass. The aim of this paper is to describe and analyze the results of our initial experience after the implementation of a same-day discharge bariatric surgery program using a telemonitoring system.

METHODS

We have completed a prospective, observational study with 14 consecutive, selected patients undergoing primary bariatric surgery (sleeve gastrectomy or Roux-en-Y gastric bypass) at a single center from April 2021 to February 2023, with home follow-up using the REVITA® telemonitoring platform (HI Iberia, S.A.) and the Home Hospitalization Unit.

RESULTS

From April 2021 to February 2023, 14 patients were selected for this program, which meant 7.3% of the total of 191 patients who underwent bariatric surgery during this period. Ten out of the 14 patients selected completed the circuit (71.4%), 4 of whom consulted the emergency department within the first 24 h (40%). There were no serious complications, readmissions or re-operations typical of bariatric surgery. The estimated savings per patient who completed the circuit was 762.

CONCLUSION

Bariatric surgery without hospital admission is feasible and safe in selected patients using a telemonitoring platform and with the support of a home hospitalization unit.

Development and Implementation of an Enhanced Recovery Protocol for Bariatric Patients in a Third World Environment

Introduction: An applicable and reproducible enhanced recovery protocol was developed and implemented to improve our outcomes in a third-world environment. Methods: We compared the results obtained prospectively. The group treated before the application of the enhanced recovery protocol was called usual care (UC) and included all bariatric surgeries operated on between 2014 and 2017. The new protocol was applied between 2017 and 2019 including all operated patients, and this group was called Fast Track (FT). The variables analyzed were the length of stay, readmissions, and complications recorded during the first 30 days. We also analyzed the milligrams of morphine used by each patient, and a cost analysis was performed. Results: During the study period, 816 patients were studied. Of these, 385 (47.2%) belonged to the UC group and 431 (52.8%) to the FT group. The mean hospital stay was 58.5 hours (UC) versus 40.3 hours (FT) (P = .0001). When comparing the global morbidity of both groups, we did not find significant differences (P = .47). There was also no statistically significant difference when comparing major complications (P = .79). No mortality was recorded. Morphine indication reported a statistically significant difference that favored FT. Costs were significantly higher in UC than in FT (P < .0001). Conclusions: We believe that the implementation of an enhanced recovery protocol in bariatric surgery is a reliable measure and can be implemented even in an underdevelopment environment enlarging the benefit for patients.

Mid-term Results of an ERAS Program of Bariatric Surgery in a Tertiary Referral Center

BACKGROUND

To identify preoperative risk factors for discharge failure beyond postoperative day two (POD-2) in bariatric surgery ERAS program in a tertiary referral center.

METHODS

all consecutive patients who underwent laparoscopic bariatric treated in accordance with ERAS protocol between January 2017 and December 2019 were included. Two groups were identified, failure of early discharge (> POD-2) (ERAS-F) and success of early discharge (≤ POD-2) (ERAS-S). Overall postoperative morbidity, unplanned readmission rates were analyzed at POD-30 and POD-90, respectively. Multivariate logistic regression was performed to determine the independent risk factors for LOS > 2 days (ERAS-F).

RESULTS

A total of 697 consecutive patients were included, 148 (21.2%) in ERAS-F group and 549 (78.8%) in ERAS-S group. All postoperative complications at POD 90, whether medical or surgical were significantly more frequent in ERAS-F group than in ERAS-S group. Neither readmission nor unplanned consultations rates at POD 90 were significantly different between both groups. History of psychiatric disorder (p = 0.01), insulin-dependent diabetes (p < 0.0001), use of anticoagulants medicine (p < 0.00001), distance to the referral center > 100 km (p = 0.006), gallbladder lithiasis (p = 0.02), and planned additional procedures (p = 0.01) were independent risk factors for delayed discharge beyond POD-2.

CONCLUSIONS

One in five patients with bariatric surgery failed to discharge earlier despite the ERAS program. Knowledge of these preoperative risk factors would allow us to identify patients who need more recovery time and a tailored approach to the ERAS protocol.

Is Same-Day Discharge After Roux-en-Y Gastric Bypass Safe? A Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Database Analysis

Purpose

Same-day discharge (SDD) after bariatric surgery is gaining popularity. We aimed to analyze the safety of SDD after Roux-en-Y gastric bypass (RYGB) and compare its outcomes to inpatients discharged on postoperative days 1–2.

Materials and Methods

We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database for the period 2015–2020. Patients who underwent primary laparoscopic RYGB and were discharged the same day of the operation (SDD-RYGB) and inpatients discharged on postoperative days 1–2 (In-RYGB) were compared. Primary outcomes of interest were overall morbidity, serious morbidity, readmission, reoperation, intervention, and mortality rates.

Results

A total of 167,188 patients were included; 2156 (1.3%) SDD-RYGB and 165,032 (98.7%) In-RYGB. Mean age (SDD-RYGB: 44.5 vs. In-RYGB: 44.6 years), proportion of females (SDD-RYGB: 81.4% vs. In-RYGB: 80.6%), and mean body mass index (SDD-RYGB: 45.8 vs. In-RYGB: 45.9 kg/m²) were similar between groups. Overall morbidity (SDD-RYGB: 11.3% vs. In-RYGB: 10.2%; OR: 1.2, p = 0.08), serious morbidity (SDD-RYGB: 3.1% vs. In-RYGB: 3%; OR: 1.03, p = 0.81), reoperation (SDD-RYGB: 1.4% vs. In-RYGB: 1.2%; OR: 1.16, p = 0.42), readmission (SDD-RYGB: 4.8% vs. In-RYGB: 4.8%; OR: 1.01, p = 0.89), and mortality (SDD-RYGB: 0.04% vs. In-RYGB: 0.09%; OR: 0.53, p = 0.53) were comparable between groups. SDD-RYGB had lower risk of 30-day interventions (SDD-RYGB: 1.1% vs. In-RYGB: 1.6%; OR: 0.64, p = 0.04) compared to In-RYGB.

Conclusion

Same-day discharge after RYGB seems to be safe and has comparable outcomes to admitted patients. Standardized patient selection criteria and perioperative management protocols are needed to further increase the safety of this practice.

Trends, Outcomes, and Impact of Early Discharge Following Bariatric Surgery: a Retrospective MBSAQIP Analysis of 748,955 Patients

INTRODUCTION

Decreasing the length of stay following bariatric surgery can reduce pressure on hospitals and surgical costs and increase patient satisfaction. We examine trends in length of hospital stay following bariatric surgery and in post-operative complications.

METHODS AND PROCEDURES

The 2015-2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was used to compile patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy. Patients were categorized into either early discharge (within one day of surgery) or late discharge, and patient and non-patient factors were compared between the two groups. A multivariable logistic regression was carried out to determine predictive factors for early discharge.

RESULTS

We evaluated 748,955 patients, with 399,918 (53%) being discharged early. Patients discharged early were younger and had fewer associated medical problems. The rate of early discharge increased between 2015 and 2019 (42.1% in 2015 vs 62.0% in 2019), while complication rates decreased or were unchanged. Multivariable analysis revealed lower ASA classification (OR 1.07; CI 1.06-1.09; p < 0.0001) and operative year (2019 vs. 2015 OR 2.26; CI 2.22-2.29; p < 0.0001) to be independently associated with early discharge. Several factors including undergoing RYGB (OR 0.44 CI 0.44-0.45; p < 0.0001), and dialysis dependence (OR 0.50; CI 0.45-0.55; p < 0.0001) among others, were associated with reduced early discharge likelihood.

CONCLUSIONS

There is a trend in bariatric surgery towards the practice of early discharge, which is safe for patients. Further work is needed to develop a set of criteria to determine which patients are best suited for this practice.

Postbariatric EArly discharge Controlled by Healthdot (PEACH) trial: study protocol for a preference-based randomized trial

Introduction

Performing bariatric surgery in a daycare setting has a potential reduction in hospital costs and increase in patients’ satisfaction. Although the feasibility and safety of such care pathway has already been proven, its implementation is hampered by concerns about timely detection of short-term complications. This study is designed to evaluate a combined outcome measurement in outpatient bariatric surgery supplemented by a novel wireless remote monitoring system versus current standard of care.

Methods and analysis

A total of 200 patients with multidisciplinary team approval for primary bariatric surgery will be assigned based on their preference to one of two postoperative trajectories: (1) standard of in-hospital care with discharge on the first postoperative day or (2) same day discharge with ongoing telemonitoring up to 7 days after surgery. The device (Healthdot R Philips) transfers heart rate, respiration rate, activity, and body posture of the patient continuously by LoRaWan network to our hospital’s dashboard (Philips Guardian). The primary outcome is a composite outcome measure within 30 days postoperative based on mortality, mild and severe complications, readmission, and prolonged length-of-stay. Secondary outcomes include patients’ satisfaction and data handling dimensions.

Endoscopic Evaluation and Management of Late Complications After Bariatric Surgery: a Narrative Review

Despite ongoing evolution in technique and a low mortality rate, clinicians may care for patients who suffer late complications (> 90 days of surgery) after bariatric surgery. Endoscopic techniques are used to identify and manage many of the late complications of the two most commonly performed bariatric surgeries: sleeve gastrectomy and Roux-en-Y gastric bypass. Stenosis at the incisura angularis and gastroesophageal reflux disease may occur in patients who have undergone a sleeve gastrectomy. Patients who underwent a Roux-en-Y gastric bypass can suffer marginal ulceration, gastrojejunal anastomotic stricture, and gastro-gastric fistula. Clinicians may also encounter biliary pathologies such as choledocholithiasis, chronic abdominal pain, and weight regain. This narrative review provides an update on the endoscopic evaluation and management of patients with late complications after sleeve gastrectomy or Roux-en-Y gastric bypass.

Randomized, Double-Blind Study of the Effect of Intraoperative Intravenous Lidocaine on the Opioid Consumption and Criteria for Hospital Discharge After Bariatric Surgery

BACKGROUND AND OBJECTIVES

Surgical trauma, pain and opioids can cause nausea, vomiting, ileus and increased length of hospital stay. The primary objective of the study was to evaluate the time to recovery of gastrointestinal function and the time to meet hospital discharge criteria after laparoscopic bariatric surgery with intraoperative intravenous lidocaine administration. Secondary objectives were to evaluate morphine consumption during the first 24 h and the side effects of opioids.

METHODS

Fifty-eight patients aged 18 to 60 years who underwent bariatric surgery were allocated into two groups. Group 1 patients received intravenous lidocaine (1.5 mg/kg) 5 min before induction of anaesthesia, followed by infusion (2 mg/kg/h) until the end of surgery. Group 2 patients were given 0.9% saline solution (placebo) and infusion of 0.9% saline solution during surgery, in same volume as group 1. Anaesthesia was performed with fentanyl (5 μg/kg), propofol (2 mg/kg), rocuronium (0.6 mg/kg) and sevoflurane. Postoperative patient-controlled analgesia was with morphine. There were two groups that were evaluated: time to recovery of gastrointestinal function and time to meet discharge criteria.

RESULTS

There was no significant difference between groups regarding the time to first flatus, time to meet discharge criteria and occurrence of side effects. Consumption of intraoperative sevoflurane and morphine over 24 h was significantly lower in the lidocaine group. Side effects observed were nausea and vomiting, with no difference between groups.

CONCLUSIONS

Perioperative intravenous lidocaine is feasible and easily accessible when administered at appropriate doses. Lidocaine reduces morphine consumption.

Fast track pathway provides safe, value based care on busy acute care surgery service

BACKGROUND

Fast track (FT) pathways have been adopted across a multitude of elective surgeries but have been slow to be adopted into the acute care surgery realm. We hypothesized that an FT pathway for acute cholecystitis patients would decrease patient length of stay and resource utilization.

METHODS

All patients at two hospitals, one with an FT pathway and one with a traditional pathway, who underwent an urgent laparoscopic cholecystectomy for acute cholecystitis between May 1, 2019, and October 31, 2019, were queried using CPT codes. Exclusion criteria were conversion to open or partial cholecystectomy. Retrospective chart review was used to gather demographics, operative, hospital course, and outcomes. Time to operating room, hospital length of stay, and resource utilization were the primary outcomes.

RESULTS

There was a total of 479 urgent laparoscopic cholecystectomies performed, 430 (89.8%) were performed under the FT pathway. The median (interquartile range [IQR]) time to the operating room was not different: 14.1 hours (IQR, 8.3-29.0 hours) for FT and 18.5 hours (IQR, 11.9-25.9 hours) for traditional (p = 0.316). However, the median length of stay was shorter by 15.9 hours in the FT cohort (22.6 hours; IQR, 14.2-40.4 hours vs. 38.5 hours; IQR, 28.3-56.3 hours; p < 0.001). Under the FT pathway, 33.0% of patients were admitted to the hospital and 75.6% were discharged from the postanesthesia care unit, compared with 91.8% and 12.2% on the traditional pathway (both p < 0.001). There were 59.6% of the FT patients that received a phone call follow up, as opposed to 100% of the traditional patients having clinic follow up (p < 0.001). The emergency department bounce back rate, readmission rates, and complication rates were similar (p > 0.2 for all). On multivariate analysis, having a FT pathway was an independent predictor of discharge within 24 hours of surgical consultation (odds ratio, 7.65; 95% confidence interval< 2.90-20.15; p < 0.001).

CONCLUSION

Use of a FT program for patients with acute cholecystitis has a significant positive impact on resource utilization without compromise of clinical outcomes.

Impact of Enhanced Recovery After Bariatric Surgery (ERABS) Protocol in Reducing Length of Stay and Hospitalization Costs: the Experience of a Philanthropic Hospital in Brazil

OVERVIEW

The global prevalence of obesity and increase in bariatric surgeries are burdening the healthcare system. Enhanced recovery postoperative protocols are associated with a reduction in hospitalization costs and length of stay (LOS) and may be an alternative to reduce public health expenses.

OBJECTIVE

To assess the impact of implementing a customized Enhanced Recovery After Bariatric Surgery (ERABS) protocol on hospitalization costs (HC), LOS, and complication rates.

SETTING

Santa Marcelina Hospital, São Paulo, Brazil.

METHODS

A retrospective electronic health record analysis of patients who underwent laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy and who were cared for within a clinical pathway (CP) protocol (Jan. 2016-Aug. 2018) or after implementation of an ERABS protocol (Aug. 2018-Jun. 2019). The LOS, HC, and complication, readmission, and reoperation rates were compared between the two groups.

RESULTS

Eighty-two patients were included in the study (CP, 56, 87.5% women; ERABS, 26, 92.3% women). Hospital LOS and total HC decreased significantly by 32.5% and 15.2%, respectively (both, p < 0.05), after implementation of ERABS. There were no significant differences in 30-day readmission, complication, or reoperation rates.

CONCLUSION

The implementation of a standardized enhanced recovery program resulted in reduced LOS and HC without an increase in perioperative morbidity. The ERABS protocol is cost-effective and can help ease the healthcare burden.

Does the Length of the Common Channel as Part of the Total Alimentary Tract Matter? One Year Results from the Multicenter Dutch Common Channel Trial (DUCATI) Comparing Standard Versus Distal Roux-en-Y Gastric Bypass with Similar Biliopancreatic Bowel Limb Lengths

PURPOSE

Although the laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is the gold-standard bariatric procedure, it remains uncertain what the optimal bowel limb lengths are to accomplish maximal weight loss while minimizing nutritional deficiencies and related gastro-intestinal complaints. The aim of this randomized controlled multicenter trial is to investigate the effect of significant lengthening of the length of the Roux limb (RL) at the cost of the length of the common channel (CC) while keeping the biliopancreatic limb (BPL) lengths the same on both study arms.

METHODS

Four hundred forty-four patients were randomized to receive either a Very Long Roux Limb LRYGB (VLRL-LRYGB) (variable RL length, BPL 60 cm, and CC 100 cm) or a Standard LRYGB (S-LRYGB) (RL 150 cm, BPL 60 cm, and a variable CC length). Results at 1-year follow-up for weight loss, effect on obesity-related comorbid conditions, complications, re-operation rate, malnutrition rate, and re-admission rate were investigated.

RESULTS

Weight loss at 1-year showed no significant differences for %EWL (84.3% versus 85.3%, p = 0.72) and %TWL (34.2% versus 33.6%, p = 0.359) comparing VLRL-LRYGB versus S-LRYGB. Malabsorption requiring surgical bowel length adjustment was observed in 1.4% in VLRL-LRYGB group versus 0.9% in S-LRYGB group (p = 0.316).

CONCLUSION

Significant lengthening of the RL at the cost of the common channel seems to have no effect on the weight loss at 1-year follow-up, which supports the theory that absorption of nutrients also occurs in the RL. Nevertheless, long-term results of the VLRL-LRYGB have to be awaited to draw final conclusions as part of the discussion towards optimal limb length in LRYGB surgery.

Does ERAS impact outcomes of laparoscopic sleeve gastrectomy in adolescents?

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols have been successfully implemented in several surgical fields; however, the application of ERAS in the pediatric population is still limited.

OBJECTIVES

The aim was to determine if implementation of an ERAS protocol can improve outcomes of laparoscopic sleeve gastrectomy (LSG) in adolescents.

SETTING

University Hospital, United States.

METHODS

A retrospective analysis of 112 adolescent patients who underwent LSG from February 2011 to July 2019 was conducted. An ERAS protocol was instituted in June 2016. Conventional care patients (n = 51) were compared with ERAS patients (n = 61). Comparisons were made using Χ² tests or Fisher's exact for categoric data and Wilcoxon-rank sum tests for continuous data. Multiple linear regression was used to adjust length of stay for patient characteristics.

RESULTS

The 2 cohorts were similar in age, sex, race, number of co-morbidities, and preoperative body mass index. The volume of intraoperative fluid, intraoperative and postoperative opioids were significantly reduced in the ERAS group (P < .0001). The number of ERAS elements received per patient increased from a median of 9 to 15 (P < .0001). ERAS group had more discharges on postoperative day 1 (48% versus 6 %, respectively). Length of stay was significantly lower in the ERAS group (2.34 versus 2.04 median d, respectively). Difference was still significant after adjusting for age, sex, race/ethnicity, payor status, American Society of Anesthesiologists score, preoperative body mass index, and the duration of surgery (P < .0001). There were no differences in postoperative complications and 30-day readmissions.

CONCLUSIONS

An LSG ERAS protocol is associated with significant reduction in perioperative opioid use and length of stay with no increase in complications or readmission rates.

Does C-reactive Protein Have a Predictive Role in the Early Diagnosis of Postoperative Complications After Bariatric Surgery? Systematic Review and Bayesian Meta-analysis

BACKGROUND

Postoperative leak and intra-abdominal infections are common after bariatric surgery with a significant impact on perioperative outcomes, hospital length of stay, and readmission rates. In the era of enhanced recovery programs, with patients being discharged from the hospital 24-36 h after surgery and potentially before developing any complications, an early indicator of postoperative complications may be decisive. The aim of this study was to evaluate the predictive role of the C-reactive protein (CRP) in the early diagnosis of complications in patients undergoing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).

METHODS

PubMed, Embase, and Web of Science databases were consulted. A systematic review and a fully Bayesian meta-analysis were conducted.

RESULTS

Seven studies met the inclusion criteria for a total of 1401 patients. Overall, 57.7% underwent LSG while 42.3% underwent LRYGB. The pooled prevalence of postoperative complications was 9.8% (95% CI = 5-16%). The estimated pooled CRP cut-off value on postoperative day 1 (POD1) was 6.1 mg/dl with a significant diagnostic accuracy and a pooled area under the curve of 0.92 (95% credible interval (CrI) 0.73-0.98). The positive and negative likelihood ratios were 13.6 (95% CrI 8.40-15.9) and 0.16 (95% CrI 0.04-0.31), respectively.

CONCLUSION

A CRP value lower than the derived cut-off of 6.1 mg/dl on POD1, combined with reassuring clinical signs, could be useful to rule out early postoperative leak and complications after LSG and LRYGB. In the context of enhanced recovery after surgery protocols, the integration of a CRP-based diagnostic algorithm as an additional complementary instrument may be valuable to reduce cost and improve outcomes and patient care.

Does the Implementation of Enhanced Recovery After Surgery (ERAS) Guidelines Improve Outcomes of Bariatric Surgery? A Propensity Score Analysis in 464 Patients

BACKGROUND

The aim of this study was to investigate whether the implementation of enhanced recovery after surgery (ERAS) guidelines according to Thorell and co. in our tertiary referral bariatric center might improve post-operative outcomes.

METHODS

ERAS program was introduced in our center since January 1, 2017. Retrospective review of a prospectively collected database identified patients who underwent laparoscopic primary and revisional bariatric surgeries from October 2005 to January 2018. Patients exposed to ERAS program ("ERAS group") were matched in a 1:1 ratio with patients exposed to conventional care (control group) using a propensity score based on age, gender, preoperative body mass index (BMI), diabetes mellitus, and the type of procedures. The primary outcome was total hospital length of stay (LOS) and the secondary outcomes included the post-operative complications and readmission rates.

RESULTS

During the study period, 464 patients were included, 232 in each group. Implementation of the ERAS protocol was significantly associated with a reduction of LOS (2.47 ± 1.7 vs 5.39 ± 1.9 days, p < 0.00001). One-third of patients was discharged (77/232, 33%) on the first postoperative day (POD) and more than three quarter of patients on POD 2 (182/232, 77%). At the opposite, no patients of the control group were discharged on POD 2. Overall 30-day and 90-day morbidity and readmission rates were the same in both groups. There was no death in each group.

CONCLUSIONS

This large case-matched study using a propensity score analysis suggests that implementation of ERAS program significantly reduced length of hospital stay without significant increases on overall morbidity, and readmission rates.

Leakage Risk Stratification After Laparoscopic Sleeve Gastrectomy (LSG): Is There a Role for Routine Postoperative CT Scan?

PURPOSE

Leakage of the gastric remnant after laparoscopic sleeve gastrectomy (LSG) represents an unpredictable, dreadful occurrence. Our aim was to assess whether routine postoperative CT scan is an effective tool for early prediction of leakage after LSG.

MATERIALS AND METHODS

From a prospectively acquired database, all consecutive patients who underwent LSG between January 2015 and December 2018 were identified; within this database, all patients who were evaluated with at least one contrast-enhanced CT scan within 48 h from surgery were enrolled in this retrospective study. The selected CT findings included twisting of the gastric remnant, perigastric air bubbles, and hematoma; the antral segment proximal from the pylorus to the first staple firing was also analyzed in terms of distance (StP, stapler to pylorus distance) and linearity (LI, linearity index).

RESULTS

After exclusions, 250 patients were included; 10 patients suffered from gastric leakage. Patients with perigastric hematoma and/or twisting of the distal part of the gastric remnant on routine postoperative CT scan were found to be more likely to develop leakage after LSG (p = 0.005 and p < 0.001, respectively). The mean StP was 45 ± 19.1 mm; the mean LI was 1.54 ± 0.4. Patients with subsequent development of leakage had significantly lower StP (26.7 ± 12.5 mm vs. 45.9 ± 18.9 mm; p = 0.001) and LI values (1.16 ± 0.11 vs. 1.55 ± 0.39; p = 0.002).

CONCLUSION

Routine postoperative CT scan after LSG permits early stratification of leakage risk, thus providing an actual aid for patients' management.

Alteration Pattern of Taste Perception After Bariatric Surgery: a Systematic Review of Four Taste Domains

BACKGROUND

Efforts continue to understand the underlying mechanism of weight loss after bariatric surgery. Taste perception has shown to be a contributing factor. However, the alteration pattern in different taste domains and among bariatric procedures has not been sufficiently investigated.

OBJECTIVES

To study the alteration pattern in the perception of four taste domains after different bariatric procedures.

SETTINGS

Private Research Institute, USA.

METHODS

A systematic review was conducted to pool available data in the literature on post-operative changes in the perception of sensitivity to four taste domains after Roux-en-Y gastric bypass (RYGB), laparoscopic sleeve gastrectomy (LSG), and adjustable gastric banding (AGB).

RESULTS

Our study showed that bariatric surgery is associated with significant change in sensitivity to all four taste domains especially salt taste, sweetness, and sourness. LSG patients showed an increased sensitivity to all four taste domains. However, RYGB patients had a variable alteration pattern of taste perception but more commonly a decreased sensitivity to sweetness and an increased sensitivity to salt taste and sourness. Additionally, AGB patients had a decreased sensitivity to sweetness, salt taste, and sourness.

CONCLUSION

Bariatric surgery is associated with taste change in a way which results in less preference for high-calorie food and possibly reduced calorie intake. This may explain one of the mechanisms by which bariatric surgery produces weight loss. However, data are heterogeneous, the potential effect dilutes over time, and the alteration varies significantly between different procedures.

Clinical Practice Guidelines for the Perioperative Nutrition, Metabolic, and Nonsurgical Support of Patients Undergoing Bariatric Procedures - 2019 Update: Cosponsored by American Association of Clinical Endocrinologists/American College of Endocrinology, The Obesity Society, American Society for Metabolic and Bariatric Surgery, Obesity Medicine Association, and American Society of Anesthesiologists

OBJECTIVE

The development of these updated clinical practice guidelines (CPGs) was commissioned by the American Association of Clinical Endocrinologists (AACE), The Obesity Society (TOS), American Society for Metabolic and Bariatric Surgery (ASMBS), Obesity Medicine Association (OMA), and American Society of Anesthesiologists (ASA) Boards of Directors in adherence with the AACE 2017 protocol for standardized production of CPGs, algorithms, and checklists.

METHODS

Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts.

RESULTS

New or updated topics in this CPG include: contextualization in an adiposity-based chronic disease complications-centric model, nuance-based and algorithm/checklist-assisted clinical decision-making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current health care arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest).

CONCLUSIONS

Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence based within the context of a chronic disease. A team approach to perioperative care is mandatory, with special attention to nutritional and metabolic issues.

Effect of Qihuang Decoction Combined with Enteral Nutrition on Postoperative Gastric Cancer of Nutrition and Immune Function

Objective

Early nutritional support in patients with gastric cancer can improve their nutritional status, but the impact on immune function has not been confirmed. This study aimed to analyze the effects of Qihuang decoction combined with enteral nutrition on nutrition and the immune function of postoperative gastric cancer.

Methods

120 patients with postoperative gastric cancer in the study group and 117 in the control group were selected as the study subjects from our hospital at random. Indications of nutrition and immune and the rates of complications were compared the day before surgery and 1, 3, 7, and 14 days after surgery.

Results

Indications of nutrition except hemoglobin (HB) in the study group were significantly higher than those before operation and the albumin (ALB) and prealbumin (TP) were significantly increased 7 and 14 days after surgery (P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 and P < 0.001 versus P < 0.001 and P < 0.001) and the protein (PA) 3, 7, and 14 days after surgery (P=0.011, P=0.002, and P=0.022) in the study group compared to those in the control group. Cellular and humoral immunity indications in the study group are significantly higher than those before operation compared to those in the control group, and the CD3⁺, CD4⁺, and CD4⁺/CD8⁺ were significantly increased 7 and 14 days after surgery (P=0.027 and P < 0.001 versus P=0.008 and P < 0.001 versus P=0.010 and P < 0.001) and IgA, IgG, and IgM 3, 7, and 14 days after surgery in the study group (P < 0.001, P < 0.001, and P < 0.001 versus P < 0.001, P < 0.002, and P < 0.001 versus P < 0.001, P < 0.001, and P < 0.001). The complications such as abdominal, lung, wound, and urinary infection were also significantly decreased (P^χ2=0.017; P < 0.001 and P < 0.001 versus P < 0.001 and P < 0.001) and the protein (PA) 3, 7, and 14 days after surgery (P=0.011, P=0.002, and P=0.022) in the study group compared to those in the control group. Cellular and humoral immunity indications in the study group are significantly higher than those before operation compared to those in the control group, and the CD3⁺, CD4⁺, and CD4⁺/CD8⁺ were significantly increased 7 and 14 days after surgery (P=0.027 and P < 0.001 versus P=0.008 and P < 0.001 versus P=0.010 and P < 0.001) and IgA, IgG, and IgM 3, 7, and 14 days after surgery in the study group (P < 0.001, P < 0.001, and P < 0.001 versus P < 0.001, P < 0.002, and P < 0.001 versus P < 0.001, P < 0.001, and P < 0.001). The complications such as abdominal, lung, wound, and urinary infection were also significantly decreased (P^χ2=0.017; P < 0.001 and P < 0.001 versus P < 0.001 and P < 0.001) and the protein (PA) 3, 7, and 14 days after surgery (P=0.011, P=0.002, and P=0.022) in the study group compared to those in the control group. Cellular and humoral immunity indications in the study group are significantly higher than those before operation compared to those in the control group, and the CD3⁺, CD4⁺, and CD4⁺/CD8⁺ were significantly increased 7 and 14 days after surgery (P=0.027 and P < 0.001 versus P=0.008 and P < 0.001 versus P=0.010 and P < 0.001) and IgA, IgG, and IgM 3, 7, and 14 days after surgery in the study group (P < 0.001, P < 0.001, and P < 0.001 versus P < 0.001, P < 0.002, and P < 0.001 versus P < 0.001, P < 0.001, and P < 0.001). The complications such as abdominal, lung, wound, and urinary infection were also significantly decreased (P^χ2=0.017; P < 0.001 and P < 0.001 versus P < 0.001 and P < 0.001) and the protein (PA) 3, 7, and 14 days after surgery (P=0.011, P=0.002, and P=0.022) in the study group compared to those in the control group. Cellular and humoral immunity indications in the study group are significantly higher than those before operation compared to those in the control group, and the CD3⁺, CD4⁺, and CD4⁺/CD8⁺ were significantly increased 7 and 14 days after surgery (P=0.027 and P < 0.001 versus P=0.008 and P < 0.001 versus P=0.010 and P < 0.001) and IgA, IgG, and IgM 3, 7, and 14 days after surgery in the study group (P < 0.001, P < 0.001, and P < 0.001 versus P < 0.001, P < 0.002, and P < 0.001 versus P < 0.001, P < 0.001, and P < 0.001). The complications such as abdominal, lung, wound, and urinary infection were also significantly decreased (P^χ2=0.017; P^χ2=0.036; P^χ2=0.041; P^χ2=0.004).

Conclusions

Qihuang decoction combined with enteral nutrition can promote the absorption of enteral nutrition with improving the immune and reducing complications of infection.

Safety and efficacy of laparoscopic sleeve gastrectomy versus laparoscopic Roux-en-Y gastric bypass: A systematic review and meta-analysis

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are widely performed to cure obesity and obesity-related diseases. Our aim was to compare these two procedures.

MATERIALS AND METHODS

An electronic literature search was performed from inception to December 2018. The clinical outcomes between LSG and LRYGB were pooled using software RevMan5.3.

RESULTS

A total of 1076 patients from 11 studies were analysed. LSG had shorter operation time (mean difference [MD] = -33.81; 95% confidence interval [CI], -46.04 to -21.57; P < .00001) and less early complications rate (risk ratio [RR] = 0.55; 95% CI, 0.36-0.84; P = .005) compared with LRYGB. There were no significant difference about the readmission rate (RR = 0.57; 95% CI, 0.21-1.54; P = .27) and re-operation rate (RR = 0.43; 95% CI, 0.14-1.27; P = .13) between LSG and LRYGB. The conversion to open rate and mortality rate within 30 days was low in both LSG and LRYGB. Mean hospital stay in LSG group (0.3-5.2 d) seems shorter than that in the LRYGB group (2.3-6.6 d). As to the effect of LSG and LRYGB on the percentage of excess weight loss (EWL), there was no significant difference between these two surgeries in EWL (MD = -4.05; 95% CI, -8.89 to 0.80; P = .10). LSG was equal to LRYGB on remission of T2DM (RR = 0.94; 95% CI, 0.84-1.06; P = .31).

CONCLUSIONS

Both LSG and LRYGB can be performed with very low conversion to open rate and mortality rate. The readmission rate and re-operation rate are comparable between these two surgeries. The efficacy of these two surgeries on EWL and T2DM is equivalent, but LSG has an advantage over LRYGB in operation time and early complications rate.

Fast Track Program in Conversion Bariatric Surgery, as Safe as in Primary Bariatric Surgery?

OBJECTIVES

Evaluate the safety of fast track (FT) surgery program in patients undergoing primary and revisional bariatric surgery (conversion from one procedure to another); identify limiting factors for early discharge and predictive factors for readmission.

METHODS

This is a retrospective review of 730 consecutive morbidly obese patients who underwent bariatric surgery between January 2016 and December 2017. Fast track protocol was applied on all patients. Target discharge was after one-night stay. The primary end point is length of stay. The secondary end point is frequency of hospital contact after discharge, readmissions and reinterventions within 30 days.

RESULTS

Primary procedures (n = 633) were banded Roux-en-Y gastric bypass (BRYGB, 79.3%), sleeve gastrectomy (10.7%), gastric band (4.7%) and others (5.3%). Mean age (± SD) was 44.32 ± 11.26 years, and mean BMI (± SD) was 43.58 ± 6.12 kg/m². Conversion procedures (n = 97) were gastric band to BRYGB (40.2%), or to adjustable BRYGB (39.2%), Mason to BRYGB (11.3%), sleeve to BRYGB (4.1%) and others (5.2%). Mean age (± SD) was 47.22 ± 9.1 years, and mean BMI (± SD) was 37.9 ± 7.27 kg/m². Mean LOS in primary patients was 1.3 ± 0.99, and that in conversion patients was 1.5 ± 1.4. Successful discharge at one night or less was achieved in 650 cases (573 primary and 77 conversion). After one-night discharge, incidence of contact to the hospital, readmission and reintervention was 23.9%, 5.9% and 1.9%, in the primary group and 31.2%, 13% and 5.2% in the conversion group.

CONCLUSION

One-night discharge in FT managed conversion procedures is safe, compared to primary procedures. It is associated with higher readmission rates; however, the postdischarge hospital contacts and surgical complications were not statistically significant different.

Clinical practice guidelines for the perioperative nutrition, metabolic, and nonsurgical support of patients undergoing bariatric procedures - 2019 update: cosponsored by American Association of Clinical Endocrinologists/American College of Endocrinology, The Obesity Society, American Society for Metabolic & Bariatric Surgery, Obesity Medicine Association, and American Society of Anesthesiologists

OBJECTIVE

The development of these updated clinical practice guidelines (CPG) was commissioned by the American Association of Clinical Endocrinologists, The Obesity Society, the American Society of Metabolic and Bariatric Surgery, the Obesity Medicine Association, and the American Society of Anesthesiologists boards of directors in adherence to the American Association of Clinical Endocrinologists 2017 protocol for standardized production of CPG, algorithms, and checklists.

METHODS

Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts.

RESULTS

New or updated topics in this CPG include contextualization in an adiposity-based, chronic disease complications-centric model, nuance-based, and algorithm/checklist-assisted clinical decision-making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current healthcare arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest).

CONCLUSIONS

Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence-based within the context of a chronic disease. A team approach to perioperative care is mandatory with special attention to nutritional and metabolic issues.

Four-Year Evolution of a Thrombophylaxis Protocol in an Enhanced Recovery After Surgery (ERAS) Program: Recent Results in 485 Patients

“Enhanced recovery after surgery” (ERAS) protocols may reduce morbidity, length of hospital stay (LOS), and costs. During the 4-year evolution of a bariatric ERAS protocol, we found that administration of thrombophylaxis selectively to high-risk morbidly obese patients (assessed postoperatively by Caprini score ≥ 3) undergoing omega loop gastric bypass (“mini” gastric bypass) or sleeve gastrectomy resulted in safe outcomes. Both procedures proved equally effective with this protocol. The vast majority of rapidly mobilized, low-risk patients did not appear to require antithrombotic heparin. Similar to other reported ERAS outcomes, our recent year’s results in 485 patients included a mean LOS of 1.08 ± 0.64 days (range 1–14), with 460 (95.0%) discharged on day 1 and 99.6% by day 2. There were 13 30-day complications (2.7%), two reinterventions (0.4%), and no hemorrhages.

Efficacy of Postoperative Upper Gastrointestinal Series (UGI) and Computed Tomography (CT) Scan in Bariatric Surgery: a Meta-analysis on 7516 Patients

BACKGROUND

To demonstrate the lack of utility and efficacy of routine early postoperative upper gastrointestinal study (UGI) in obese patients undergoing bariatric surgery and to show the higher efficacy of CT scan in cases of clinical suspicion of a leakage, a meta-analysis was performed.

MATERIALS AND METHODS

A literature search including articles published in last 18 years was performed. For both UGI and CT scan, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. A first analysis considered overall patients, and a second analysis considered only symptomatic patients.

RESULTS

Starting from 1233 eligible citations, 18 articles, including 7516 patients, were left. The pooled sensitivity was 54% for UGI (95% CI 34-74) with a high heterogeneity (I² = 99.8%, p < .001), whereas CT scan showed a pooled sensitivity of 91% (95% CI 89-93) significantly higher than sensitivity of UGI series (p < 0.01), with a high heterogeneity (I² = 98.9%, p < .001). In symptomatic patients the pooled sensitivity of UGI series was significantly lower than sensitivity of CT scan [49% (95% CI 31-68) vs 94% (95% CI 92-96), p < 0.01]. PPV showed a significant difference between UGI series and CT scan (54 vs 100%, p < 0.01). Specificity for UGI series was 98.6%, and specificity for CT scan was 99.7% (p = ns); the mean NPV was 96 and 98% for UGI series and CT scan (p = ns).

CONCLUSIONS

According to our results, a CT scan triggered by clinical suspicion must be considered the first-line procedure to detect a postoperative leak following primary sleeve gastrectomy or Roux-en-Y gastric bypass.

Hospital utilization 4 years after bariatric surgery: sleeve gastrectomy versus Roux-en-Y gastric bypass

BACKGROUND

While sleeve gastrectomy (SG) has lower perioperative risk compared with Roux-en-Y gastric bypass (RYGB), long-term data about their differential impact on overall health are unclear. Hospital use after bariatric surgery is an important parameter for improving peri- and postoperative care.

OBJECTIVE

This present study was aimed to compare SG and RYGB in terms of their effect on long-term hospital-based healthcare utilization.

SETTING

Multicenter, statewide database.

METHODS

A retrospective cohort study of adult patients who underwent SG and RYGB between 2009 and 2011, with follow-up until 2015 and 2-year presurgery information. Propensity score-matched SG and RYGB groups were created using preoperative demographic characteristics, co-morbidities, and presurgery hospital use, measured by cumulative length of stay (LOS) and frequency of emergency department visits. Postsurgery yearly LOS, incidence of hospital visits, and the reason for the visit were compared. Primary outcomes included postoperative hospital visits during years 1 to 4 after bariatric surgery and cumulative LOS. Secondary outcomes included specific reasons for hospital use.

RESULTS

There were 3540 SG and 13,587 RYGB patients, whose mean (95% confidence interval [CI]) LOS was 1.3 (1.3-1.4), .9 (.8-1), 1 (.9-1.1), and 1.2 (1-1.3) days at years 1 through 4, respectively. Postoperative yearly LOS was similar between the 2 propensity-matched groups. The risk of hospitalizations (odd ratio .73, 95% CI .64-.84, P < .0001) and emergency department visits (odds ratio .84, 95% CI .75-.95, P = .005) was significantly lower for SG, during the first postoperative year. The reverse was seen at the fourth postoperative year, with higher risk of emergency department use after SG (odds ratio 1.16, 95% CI 1.01-1.33, P = .035).

CONCLUSION

Postoperative 4-year hospital utilization remains low for both SG and RYGB. The previously established lower early perioperative risk of SG was not appreciated for longer-term hospital use compared with RYGB.

Laparoscopic sleeve gastrectomy follow-up: use of connected devices in the postoperative period

BACKGROUND

During the last decade, laparoscopic sleeve gastrectomy (LSG) has become the most performed bariatric procedure worldwide.

OBJECTIVES

To evaluate the feasibility of the use of connected devices in monitoring patients operated on by LSG and discharged 24 hours after surgery under the enhanced recovery after surgery protocol.

SETTING

Private hospital, France.

METHODS

This is a prospective pilot study designed to assess the risk and benefit of using connected devices in the postoperative follow-up of patients operated on by LSG. Patients operated on with LSG were discharged 24 hours after surgery, and vital signs such as blood pressure, heart rate, peripheral capillary oxygen saturation, and temperature were monitored via connected devices with data sent to an internet platform to make them immediately viewable by the surgeon.

RESULTS

The study population consisted of 82 women and 18 men. The mean body mass index was 43.4 kg/m², and the mean age was 39.6 years. Two patients were reoperated on for bleeding and, consequently, were excluded from the study. At postoperative day 8, 1 patient presented with tachycardia, fever, and mild abdominal discomfort. After the alert was received from the internet platform, the patient was immediately contacted, admitted to the ward, and promptly reoperated on. At 1 year after the surgery, the mean percentage of excess weight loss and total weight loss were 68.1 ± 18.1% and 36 ± 9.8 kg, respectively. For the patients not available for follow-up at the 1-year control, weight loss data were extrapolated from the internet platform. Globally, 92% of patients felt safe when they returned home, and 92% of patients would recommend this way of managing the postoperative period.

CONCLUSIONS

In conclusion, this study shows that the early postoperative follow-up to an intervention such as LSG can be done at the patient's home under the monitoring of connected devices without a risk of increase in the rate of complications and rehospitalization. The role of the connected devices in the long-term postoperative follow-up seems promising.

Enhanced recovery after surgery (ERAS) in one-anastomosis gastric bypass surgery: a matched-cohort study

BACKGROUND

One-anastomosis gastric bypass (OAGB) is considered new from the bariatric standpoint.

OBJECTIVES

To assess the effectiveness and safety of the enhanced recovery after surgery protocol compared with the conventional approach in perioperative care of OAGB patients.

SETTING

Turkey.

METHODS

The prospectively collected data of 92 patients managed with standard care (group 1) were compared with 216 patients managed by the enhanced recovery after surgery pathway (group 2). All patients underwent OAGB by the same surgeon. The groups were compared in terms of mean postoperative length of stay; costs for surgery and recovery; and rates of complications, emergency room visits, and readmissions.

RESULTS

Length of stay was always 5 days in group 1 and had a mean of 1.2 ± 1.3 days in group 2 (P < .001). The mean total cost for surgery and recovery was 858.6 ± 33.1 USD in group 1 and 625.2 ± 289.1 USD in group 2 (P < .001). Specific complications (Clavien-Dindo IIIa) occurred in 1 patient (1.1%) in group 1 and in 3 patients (1.4 %) in group 2 (P = 1.000). Fifty-seven patients (61.9%) in group 1 and 45 (20.9%) in group 2 visited the emergency room within 1 month of being discharged (P < .001). Two patients (.9%) in group 2 needed hospital readmission; there was no need for rehospitalization in group 1 (P < .001).

CONCLUSION

The enhanced recovery after surgery pathway significantly reduces length of stay and cost after OAGB, with no significant difference in terms of surgical outcomes. It also reduces postdischarge resource utilization.
