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

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.

Perioperative outcomes of same-day discharge laparoscopic Roux-en-Y gastric bypass using the MBSAQIP database

BACKGROUND

There has been a rising trend of outpatient bariatric surgery, particularly accelerated by the COVID-19 pandemic. The aim of this study was to evaluate the safety and outcomes of same-day discharge laparoscopic Roux-en-Y gastric bypass (LRYGB) using the MBSAQIP database.

METHODS

In this retrospective study, the MBSAQIP was queried for patients undergoing non-revisional LRYGB between 2020 and 2021. Two cohorts were established: same-day discharge (SDD; length of stay = 0 days) and next-day discharge (POD1; length of stay = 1 day), with the latter serving as a control group. Univariate analysis and multivariate logistic regression were employed to compare outcomes between cohorts.

RESULTS

A total of 48,408 patients underwent LRYGB, with 1,918 (4.0%) SDD and 46,490 (96.0%) POD1. The two cohorts were similar in mean age (SDD 44.2 ± 11.3 years vs POD1 44.0 ± 11.3 years; p = 0.61) and female sex (SDD 83.8% vs POD1 83.1%; p = 0.43). However, the POD1 cohort had a higher preoperative body mass index (45.4 ± 7.3 vs 44.9 ± 7.3 kg/m2; p < 0.01). Preoperative anticoagulation and obstructive sleep apnea were more prevalent in the POD1 group. There was no difference in overall 30-day overall complication rates (SDD 2.0% vs POD1 2.3%; p = 0.51), reintervention, reoperations, mortality, and emergency department visits between the two cohorts. Readmissions were lower in the SDD cohort (2.9% vs 4.0%; p = 0.02), whereas the need for outpatient intravenous hydration was higher in the SDD cohort (6.7% vs 3.6%; p < 0.01). This finding remained significant even after adjustment for confounders.

CONCLUSION

Same-day LRYGB is safe and feasible, with comparable complication rates to next-day discharge. Notably, SDD is associated with lower readmission rate and higher need for outpatient intravenous hydration, possibly reflecting rigorous bariatric protocols and thorough patient follow-up. Further investigations are warranted to elucidate the selection criteria and optimize postoperative care for outpatient LRYGB.

Continuous monitoring after laparoscopic Roux-En-Y gastric bypass: a pathway to ambulatory care surgery - a pilot study

Same-day discharge (SDD) after Laparoscopic Roux-En-Y Gastric Bypass (LRYGB) faces resistance due to possible undetected postoperative complications. These present with changes in vital signs, which continuous remote monitoring devices can detect. This study compared continuous vital signs monitoring using the Isansys Patient Status Engine™ with standard nursing vital signs measurements to assess the device's reliability in postoperative surveillance of patients undergoing LRYGB. We conducted a pilot study including patients who underwent LRYGB. During their hospital stay, patients were continuously monitored using the Isansys Patient Status Engine™ with Lifetouch™, Lifetemp™, and Nonin Pulse Oximeter™ sensors. The heart rate (HR), body temperature, and oxygen saturation (SpO2) collected by the device were compared with standard nursing assessments. Thirteen patients with a mean body mass index of 41.5 ± 4.4 kg/m2 were included. No major complications occurred. The median HR assessed by standard and continuous monitoring did not significantly differ (75.5 [69-88] vs. 77 [66-91] bpm, p = 0.995), nor did the mean values of SpO2 (94.7 ± 2.0 vs. 93.7 ± 1.8%, p = 0,057). A significant difference was observed in median body temperature between the nursing staff and the monitoring device (36.3 [36.1-36.7] vs. 36.1 [34.5-36.6] degrees Celsius, p = 0.012), with a tendency for lower temperature measurements by the device. In conclusion, this is the first study on continuous postoperative surveillance using the Isansys Patient Status Engine™ monitoring device for LRYGB patients. Our results introduce a novel tool for more efficient surgery. Prospective randomized experimental studies are warranted to evaluate this method's efficacy and safety.

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.

Safety of gastric bypass with same-day discharge: a propensity score-matched analysis of the Dutch Audit for treatment of Obesity

BACKGROUND

Bariatric surgery with same-day discharge (SDD) is becoming increasingly common. Nevertheless, there is limited data available comparing gastric bypass patients with SDD to those with overnight hospitalization.

OBJECTIVE

The aim of this study was to investigate the short-term outcomes of gastric bypass with SDD compared to overnight hospitalization in The Netherlands.

SETTING

Retrospective database study with the use of the Dutch national registry.

METHODS

Patients who underwent gastric bypass surgery in 2022 were included and propensity score matching was performed to compare SDD with patients discharged on postoperative days (POD) 1-4. The primary outcome was the occurrence of severe complications within 30 days postoperative.

RESULTS

A total of 775 SDD patients were matched with 1550 patients discharged on POD 1-4. The occurrence of severe complications was .9% in both groups (P = 1.000), and there were no significant differences in reoperations or mortality. A significant difference was observed in the readmission rate, with 3.9% in the SDD group compared to 1.6% in the other group (P = .001). A proportionally small, yet statistically significant difference favored the control group regarding anastomotic leakages (.6% versus 0%, P = .004) and unspecified surgical complications (1.4% versus .5%, P = .028).

CONCLUSION

Gastric bypass with SDD is safe, with no increased risk of short-term severe complications, reoperations, or mortality. However, SDD is associated with a higher 30-day readmission rate compared to patients who stay overnight in the hospital after surgery.

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.

Application of machine learning to predict postoperative gastrointestinal bleed in bariatric surgery

BACKGROUND

Postoperative gastrointestinal bleeding (GIB) is a rare but serious complication of bariatric surgery. The recent rise in extended venous thromboembolism regimens as well as outpatient bariatric surgery may increase the risk of postoperative GIB or lead to delay in diagnosis. This study seeks to use machine learning (ML) to create a model that predicts postoperative GIB to aid surgeon decision-making and improve patient counseling for postoperative bleeds.

METHODS

The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was used to train and validate three types of ML methods: random forest (RF), gradient boosting (XGB), and deep neural networks (NN), and compare them with logistic regression (LR) regarding postoperative GIB. The dataset was split using fivefold cross-validation into training and validation sets, in an 80/20 ratio. The performance of the models was assessed using area under the receiver operating characteristic curve (AUROC) and compared with the DeLong test. Variables with the strongest effect were identified using Shapley additive explanations (SHAP).

RESULTS

The study included 159,959 patients. Postoperative GIB was identified in 632 (0.4%) patients. The three ML methods, RF (AUROC 0.764), XGB (AUROC 0.746), and NN (AUROC 0.741) all outperformed LR (AUROC 0.709). The best ML method, RF, was able to predict postoperative GIB with a specificity and sensitivity of 70.0% and 75.4%, respectively. Using DeLong testing, the difference between RF and LR was determined to be significant with p < 0.01. Type of bariatric surgery, pre-op hematocrit, age, duration of procedure, and pre-op creatinine were the 5 most important features identified by ML retrospectively.

CONCLUSIONS

We have developed a ML model that outperformed LR in predicting postoperative GIB. Using ML models for risk prediction can be a helpful tool for both surgeons and patients undergoing bariatric procedures but more interpretable models are needed.

Evaluation of Postoperative Care Protocol for Roux-en-Y Gastric Bypass Patients with Same-Day Discharge

INTRODUCTION

Same-day discharge (SDD) after bariatric surgery is increasingly being performed and is safe with careful patient selection. However, detecting early complications during the first postoperative days can be challenging. We developed a postoperative care protocol for these patients and aimed to evaluate its effectiveness in detecting complications and monitoring patient recovery.

METHODS

A single-center retrospective observational study was conducted with patients with who underwent Roux-en-Y Gastric Bypass (RYGB) with successful SDD. The study evaluated the effectiveness of the safety net that included simple remote monitoring with a pulsoximeter and thermometer, a phone consultation on postoperative day (POD) 1, and a physical consultation on POD 2-4. Furthermore, an analysis was performed on various factors including pain scores, painkiller usage, and incidences of nausea and vomiting on POD 1.

RESULTS

In this study, 373 consecutive patients were included, of whom 19 (5.1%) were readmitted until POD 4. Among these, 12 patients (3.2%) reached out to the hospital themselves, while 7 (1.9%) were readmitted after phone or physical consultations. Ten of the readmitted patients had tachycardia. On POD 1, the mean numeric rating scale was 4 ± 2, and 96.6% of the patients used acetaminophen, 35.5% used naproxen, and 9.7% used oxynorm. Of the patients, 13.9% experienced nausea and 6.7% reported vomiting.

CONCLUSION

A postoperative care protocol for SDD after RYGB, comprising simple remote monitoring along with a phone consultation on POD 1 and a physical checkup on POD 2-4, was effective in monitoring patient recovery and detecting all early complications.

One-Anastomosis Gastric Bypass Versus Roux-en-Y Gastric Bypass as Revisional Surgery After Sleeve Gastrectomy: a Systematic Review and Meta-analysis

The demand for revisional bariatric surgery after sleeve gastrectomy (SG) has increased, but the ideal procedure remains unclear. A systematic review and meta-analysis were performed to compare the outcomes of weight loss and safety of one-anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) as revisional procedures for failed SG. Four retrospective comparative studies were included, comprising 499 individuals. Patients submitted to OAGB had a more significant total weight loss (TWL) (MD =  - 5.89%; 95% CI - 6.80 to - 4.97) after revisional surgery. Overall early complication rate was similar between procedures (RD = 0.04; 95% CI: - 0.05 to 0.12). Limited and heterogeneous data prevent meaningful conclusions, but the present analysis suggests that OAGB has a better TWL after revisional surgery.
