Gastric sleeve resection as day-case surgery: what affects the discharge time?

Safety of Same-Day Discharge after Bariatric Surgery: Retrospective 6-Year North American Analysis

BACKGROUND

With increasing implementation of Enhanced Recovery After Surgery protocols and rising demand for inpatient hospital beds accentuated by COVID-19, there has been interest in same-day discharge (SDD) for bariatric surgery. The aim of this study was to determine the national trends, safety profile, and risk factors for complications of SDD for minimally invasive bariatric surgery.

STUDY DESIGN

We analyzed the MBSAQIP database from 2016 to 2021 to characterize trends in SDD for minimally invasive bariatric operation. Multivariate logistic regression was performed on preoperative patient characteristics predictive of increased complications associated with SDD. A comparative analysis of postoperative outcomes within 30 days was performed for SDD and admission after 1:1 nearest neighbor propensity score matching for patient demographics and preoperative comorbidities.

RESULTS

SDD increased from 2.4% in 2016 to 7.4% in 2021. Major preoperative factors associated with increased complications for SDD included Black race, history of MI, renal insufficiency, deep vein thrombosis, and smoking. SDD for Roux-en-Y gastric bypass had 72% increased risk of postoperative complications compared with sleeve gastrectomy. The overall major complications were lower in SDD cohort vs admission cohort (odds ratio [OR] 0.62, p < 0.01). However, there was a significant increase in deaths within 30 days (OR 2.11, p = 0.01), cardiac arrest (OR 2.73; p < 0.01), and dehydration requiring treatment (OR 1.33; p < 0.01) in SDD cohort compared with admission cohort.

CONCLUSIONS

Nationally, there has been a rise in SDD for bariatric operation from 2016 to 2021. Matched analysis demonstrates that SDD is associated with a significantly higher mortality rate. Additionally, the risk of complications with SDD is higher for RYGB compared with sleeve gastrectomy. Therefore, further studies are required to appropriately select patients for whom bariatric surgery can be safely performed as an outpatient.

A Prospective Multicenter Standard of Care Study of Outpatient Laparoscopic Sleeve Gastrectomy

A global shift is occurring as hospital procedures move to ambulatory surgical settings. Surgeons have performed outpatient sleeve gastrectomy (SG) in bariatric surgery since 2010. However, prospective trials are needed to ensure its safety before widespread adoption.

PURPOSE

The study aimed to present a comprehensive report on the prospective data collection of 30-day outcomes of outpatient primary laparoscopic SG (LSG). This trial seeks to assess whether outpatient LSG is non-inferior to hospital-based surgery in selected patients who meet the outpatient surgery criteria set by the American Society for Metabolic and Bariatric Surgery.

MATERIALS AND METHODS

This study is funded by the Society of American Gastrointestinal and Endoscopic Surgeons and has been approved by the Advarra Institutional Review Board (Pro00055990). Cognizant of the necessity for a prospective approach, data collection commenced after patients underwent primary LSG procedures, spanning from August 2021 to September 2022, at six medical centers across the USA. Data centralization was facilitated through ArborMetrix. Each center has its own enhanced recovery protocols, and no attempt was made to standardize the protocols.

RESULTS

The analysis included 365 patients with a mean preoperative BMI of 43.7 ± 5.7 kg/m2. Rates for 30-day complications, reoperations, readmissions, emergency department visits, and urgent care visits were low: 1.6%, .5%, .2%, .2%, and 0%, respectively. Two patients (0.5%) experienced grade IIIb complications. There were no mortalities or leaks reported.

CONCLUSION

The prospective cohort study suggests that same-day discharge following LSG seems safe in highly selected patients at experienced US centers.

Patient's Preference for Same-Day Discharge or Hospitalization After Bariatric Surgery

PURPOSE

Enhanced Recovery After Bariatric Surgery protocols have proven to be effective in reducing complication rates and length of stay. Guidelines do not include a recommendation on the length of hospital stay whereas same-day discharge is currently widely investigated on safety and feasibility. However, none of these studies takes patient preferences into account. The study aimed to reveal the patient's preference for outpatient surgery (OS) in patients who underwent primary bariatric surgery.

MATERIALS AND METHODS

A single-center preference-based randomized trial was performed between March and December of 2021. Adult patients planned for primary bariatric surgery were able to choose their care pathway, either OS with remote heart and respiratory rate monitoring by a wearable data logger or standard care with at least one-night hospitalization.

RESULTS

Out of the 202 patients, nearly everyone (98.5%) had a preference. Of 199 patients, 99 (49.7%) chose inpatient surgery. Of the 100 with a preference for OS, 23 stayed in the hospital due to medical reasons and 12 patients changed their preference. Based on both initial preference and changed preference, there were no differences between sex, age, body mass index, and co-morbidities such as diabetes mellitus, hypertension, and atrial fibrillation, nor in the use of anticoagulants or type of surgery.

CONCLUSION

Patients seemed to have a strong preference for their stay after a bariatric procedure. The preference is equally divided between outpatient and inpatient surgery and is not influenced by any patient characteristics.

Laparoscopic-Assisted Transversus Abdominis Plane (TAP) Block Versus Port-Site Infiltration with Local Anesthetics in Bariatric Surgery: a Double-Blind Randomized Controlled Trial

BACKGROUND

The transversus abdominis plane (TAP) block has shown great potential usefulness in the management of postoperative pain; however, there is lacking evidence regarding its use in bariatric surgery. This randomized double-blind trial was aimed at comparing the effectiveness of the TAP block and port-site infiltration (PSI) in patients undergoing bariatric surgery.

METHODS

We included patients ≥ 18 years old undergoing bariatric surgery. From July 2020 to July 2021, all eligible patients were randomized to receive either laparoscopic-assisted TAP block or PSI. Demographic and clinical data were collected and analyzed.

RESULTS

During the study period, we included 113 patients. Fifty-one were allocated to the TAP block group and 62 to the PSI group. The mean age was 47.9 ± 11.2 years, 88 (77.9%) patients were female, and mean BMI was 40.5 ± 5.9 kg/m2. Operative time was 110 ± 42 min vs. 114 ± 41 min in the TAP block and PSI groups (p = 0.658). At 24 h after surgery, pain on the VAS was 2.5 ± 2.6 vs. 2.3 ± 2.1 (p = 0.661). No significant difference between the groups was noted at 3, 6, 12, and 18 h. Also, opioid and antiemetic consumption, the length of stay (3.4 ± 1.5 days vs. 3.2 ± 1.1 days, p = 0.392), and satisfaction score (154 ± 10 pts vs. 154 ± 16 pts, p = 0.828) were similar in the two groups.

CONCLUSIONS

Patients undergoing bariatric surgery and receiving either the TAP block or the PSI had similar postoperative pain, nausea, length of stay, and satisfaction. As PSI is technically easier and more reproducible, it might be the first choice for postoperative multimodal analgesia in bariatric surgery.

Outcomes of same-day discharge sleeve gastrectomy and Roux-en-Y gastric bypass: a systematic review and meta-analysis

Length of stay after bariatric surgery has progressively shortened. Same-day discharge (SDD) has been reported for the 2 most common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). The aim of this study is to evaluate the safety and success of SDD following SG and RYGB. Systematic literature search on SDD after bariatric surgery was conducted in Medline, Cochrane library, Google Scholar, and Embase. SDD was defined as discharging the patient during the day of the bariatric operation, without an overnight stay. The primary outcomes of interest were successful SDD, readmission, and morbidity rates. The secondary endpoints included reoperation and mortality rates. A proportion meta-analysis was performed to assess the outcomes of interest. A total of 14 studies with 33,403 patients who underwent SDD SG (32,165) or RYGB (1238) were included in the qualitative synthesis. Seven studies with 5000 patients who underwent SDD SG were included in the quantitative analysis, and pooled proportions (PPs) were calculated for the outcomes of interest. The SDD success rate was 63%-100% (PP: 99%) after SG and 88%-98.1% after RYGB. The readmission rate ranged from .6% to 20.8% (PP: 4%) after SDD SG and 2.4%-4% after SDD RYGB. Overall morbidity, reoperation, and mortality were 1.1%-10% (PP:4%), .3%-2.1% (PP: 1%), and 0%-.1% (PP: 0%), respectively, for SDD SG, and 2.5%-4%,1.9%-2.5%, and 0%-.9%, respectively, for SDD RYGB. SDD after SG seems feasible and safe. The outcomes of SDDRYGB seem promising, but the evidenceis stilllimitedto draw definitive conclusions. Selection criteria and perioperative protocolsmust be standardized to adequately introduce this practice.

Telemonitoring for perioperative care of outpatient bariatric surgery: Preference-based randomized clinical trial

IMPORTANCE

Implementation of bariatric surgery on an outpatient basis is hampered by concerns about timely detection of postoperative complications. Telemonitoring could enhance detection and support transition to an outpatient recovery pathway.

OBJECTIVE

This study aimed to evaluate non-inferiority and feasibility of an outpatient recovery pathway after bariatric surgery, supported by remote monitoring compared to standard care.

DESIGN

Preference-based non-inferiority randomized trial.

SETTING

Center for obesity and metabolic surgery, Catharina hospital Eindhoven, the Netherlands.

PARTICIPANTS

Adult patients scheduled for primary gastric bypass or sleeve gastrectomy.

INTERVENTIONS

Same-day discharge with one week ongoing Remote Monitoring (RM) of vital parameters or Standard Care (SC) with discharge on postoperative day one.

MAIN OUTCOMES

Primary outcome was a thirty-day composite Textbook Outcome score encompassing mortality, mild and severe complications, readmission and prolonged length-of-stay. Non-inferiority of same-day discharge and remote monitoring was accepted below the selected margin of 7% upper limit of confidence interval. Secondary outcomes included admission duration, post-discharge opioid use and patients' satisfaction.

RESULTS

Textbook Outcome was achieved in 94% (n = 102) in RM versus 98% (n = 100) in SC (RR 2.9; 95% CI, 0.60-14.23, p = 0.22). The non-inferiority margin was exceeded which is a statistically inconclusive result. Both Textbook Outcome measures were above Dutch average (5% RM and 9% SC). Same-day discharge reduced hospitalization days by 61% (p<0.001) and by 58% with re-admission days included (p<0.001). Post-discharge opioid use and satisfaction scores were equal (p = 0.82 and p = 0.86).

CONCLUSION

In conclusion, outpatient bariatric surgery supported with telemonitoring is clinically comparable to standard overnight bariatrics in terms of textbook-outcome. Both approaches reached primary endpoint results above Dutch average. However, statistically the outpatient surgery protocol was neither inferior, nor non-inferior to the standard pathway. Additionally, offering same-day discharge reduces the total hospitalization days while maintaining patient satisfaction and safety.

Enhanced recovery after bariatric surgery: an Italian consensus statement

Background

Enhanced recovery after bariatric surgery (ERABS) is an approach developed to improve outcomes in obese surgical patients. Unfortunately, it is not evenly implemented in Italy. The Italian Society for the Surgery of Obesity and Metabolic Diseases and the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care joined in drafting an official statement on ERABS.

Methods

To assess the effectiveness and safety of ERABS and to develop evidence-based recommendations with regard to pre-, intra-, and post-operative care for obese patients undergoing ERABS, a 13-member expert task force of surgeons and anesthesiologists from Italian certified IFSO center of excellence in bariatric surgery was established and a review of English-language papers conducted. Oxford 2011 Levels of Evidence and U.S. Preventive Services Task Force Grade Definitions were used to grade the level of evidence and the strength of recommendations, respectively. The supporting evidence and recommendations were reviewed and discussed by the entire group at meetings to achieve a final consensus.

Results

Compared to the conventional approach, ERABS reduces the length of hospital stay and does not heighten the risk of major post-operative complications, re-operations, and hospital re-admissions, nor does it increase the overall surgical costs. A total of 25 recommendations were proposed, covering pre-operative evaluation and care (7 items), intra-operative management (1 item, 11 sub-items), and post-operative care and discharge (6 items).

Conclusions

ERABS is an effective and safe approach. The recommendations allow the proper management of obese patients undergoing ERABS for a better outcome.

Pancreatic Leak After a Laparoscopic Sleeve Gastrectomy

INTRODUCTION

Severe adhesions in patients with previous abdominal operations may lead to a more challenging subsequent bariatric surgery [1, 2]. In this context, sleeve gastrectomy (SG) is the preferred weight loss surgery since it solely involves stomach resection (without bowel involvement) in one abdominal compartment. Additionally, SG has lower complication rates and a shorter operative time than other bariatric procedures [3, 4]. In this paper, we present a multimedia video of the management of a pancreatic leak after SG in a patient with multiple previous abdominal surgeries.

MATERIALS AND METHODS

A 40-year-old female with a BMI of 36 kg/m² and obesity-related comorbidities presented to our clinic for bariatric surgery evaluation. The patient had a history of a motor vehicle accident requiring a splenectomy, a liver laceration requiring packing and reoperation with an open abdomen for more than a month. This was followed by a hernia repair with component separation. Preoperative workup was completed, including an upper endoscopy (EGD) that was negative for esophagitis. The computed tomography (CT) scan showed an area in the left upper quadrant with no bowel loops adherent to the abdominal wall, thus a safer area for accessing the abdominal cavity (Fig. 1). The SG itself was challenging due to severe adhesions. These adhesions were between the bowel and abdominal wall, bowel and bowel, stomach and liver, and posterior stomach and pancreas (video). Once adhesiolysis was completed, the stomach was tailored successfully without intraoperative complications. The patient was discharged on postoperative day 1 with stable vitals and laboratory exams while tolerating a liquid diet.

RESULTS

On postoperative day 2, the patient returned to the emergency department with abdominal pain, increased heart rate (120 per minute), and a white blood cell count (WBC) of 20,000 th/µL. The CT scan showed a left upper quadrant collection with no evidence of air or contrast extravasation from the sleeve, as shown in Fig. 2. The patient became unstable and did not respond adequately to resuscitation efforts. Due to the extensive dissection in the primary operation, we elected to perform a laparoscopic exploration on an urgent basis. A collection (dark fluid) was noted in the left upper quadrant, but no sleeve staple line leak was found even with the air leak test (Fig. 2). Drainage and wash out were completed, and 2 abdominal drains were placed. Although the patient had symptomatic improvement postoperatively, an EGD with fluoroscopy was repeated, and no leak was noted (Fig. 3). The fluid evaluation showed increased lipase suggesting the diagnosis of a pancreatic leak. A liquid diet was initiated, and the initial drain in the left upper quadrant was exchanged to a higher caliber one (16F 40 cm locking loop drain). The patient was stable and eventually discharged home on postoperative day 6. Eventually, the drains were draining less than 10 mL and then downsized and removed. The patient's weight loss journey continued afterward with no other complications at 10-month follow-up.

CONCLUSIONS

Pancreatic leak is a rare but potentially severe complication after SG, especially in the difficult abdomen.

The effects of fentanyl, oxycodone, and butorphanol on gastrointestinal function in patients undergoing laparoscopic hysterectomy: a prospective, double-blind, randomized controlled trial

Background

Perioperative opioid use is associated with postoperative bowel dysfunction, which causes longer hospital stay and higher healthcare costs. This study aimed to investigate the effect of the equivalent doses of fentanyl, oxycodone, and butorphanol on bowel function in patients undergoing laparoscopic hysterectomy.

Methods

In this randomized controlled trial, 135 patients undergoing laparoscopic hysterectomy received postoperative intravenous patient-controlled analgesia (IV-PCA) with fentanyl 8.3 μg/kg, butorphanol 0.16 mg/kg, and oxycodone 0.5 mg/kg (1: 20: 60), respectively. The primary outcome measure was the recovery of bowel function. We also evaluated and recorded the following nine indicators: pain score, sedation level, leukocyte count, percentage of neutrophils, plasma potassium levels, time to first ambulation, postoperative side effects, patients' satisfaction, and postoperative hospital length of stay.

Results

The mean time to flatus was significantly prolonged in Group B (45.2 ± 11.6 h) compared with Group F (33.1 ± 11.2 h, P < 0.001) and Group O (36.2 ± 10.9 h, P = 0.001). The incidence of somnolence and dizziness prove higher in Group B (P < 0.001). No statistical difference was observed in the mean time to tolerate oral diet, time to defecation, analgesic outcome, satisfaction score, time to first ambulation, and postoperative hospital length of stay.

Conclusions

Compared with fentanyl and oxycodone, butorphanol prolonged the recovery of bowel function with more severe somnolence and dizziness, suggesting that butorphanol is not well suitable for IV-PCA in patients undergoing laparoscopic hysterectomy.

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.

Influencing factors for delayed discharge following day surgery: A retrospective case-control study

AIM

We aimed to identify the risk factors for delayed discharge in a day surgery centre in west China.

BACKGROUND

Delayed discharge affected by various factors is a key indicator for healthcare quality of day surgery. However, few studies have focused on this issue in developing countries where the day surgery started much later.

DESIGN

A retrospective case-control design.

METHOD

A random sample of 169 delayed discharge cases and 514 normal discharge cases was randomly selected from 38,021 day surgery cases from May 2011 to May 2019 in a tertiary teaching hospital in west China. Socio-demographic and clinical characteristics of patients were collected through the hospital electronic database and a chart review. A multivariate logistic regression was conducted to identify the risk factors for delayed discharge.

RESULTS

The urban employee basic medical insurance, comorbidity, general anaesthesia, pain, fever, bleeding and metabolic disorder were identified as the risk factors for delayed discharge. Living in the city where the hospital located was a protective factor for delayed discharge.

CONCLUSION

Post-operative complications including fever, pain, bleeding and metabolic disorder were the most important risk factors for delayed discharge. The pre-operative prevention, careful monitoring and rapid reactions to post-operative complications may reduce delayed discharge.

SUMMARY STATEMENT

What is already known about this topic? Day surgery is conducted worldwide due to its time-saving, cost-effectiveness and low risk for post-operative infection. Delayed discharge is considered as one of the most important indicators for healthcare quality of a day surgery centre. Most of the identified risk factors for delayed discharge are from the developed countries' experience of day surgery and remain controversial. What this paper adds? The insurance reimbursement rate influenced patients' willingness for discharge. Living in the same city where the hospital is located was a protective factor for delayed discharge. Post-operative metabolic disorder was a risk factor for delayed discharge. The implications of this paper: Reducing the insurance reimbursement rate of patients who meet discharge criteria but ask for longer hospital stays may be helpful to reduce delayed discharge. Careful monitoring and rapid response to post-operative complications may be simple but useful measures to reduce the risk of delayed discharge.
