Ambulatory laparoscopic cholecystectomy: Systematic review and meta-analysis of predictors of failure

Feasibility of an < 24 h discharge pathway with tele-monitoring after elective colectomies: a pilot study

INTRODUCTION

Implementation of enhanced recovery after surgery principles has led to exploration of ambulatory pathways in surgery, including gastrointestinal surgery. However, implementation of ambulatory pathways after colorectal surgery has not been established yet. Previous studies suggest that discharge within 24 h in colorectal surgery is only possible with a clear protocol and careful patient selection.

METHODS

Single center prospective feasibility pilot study of thirty patients in one large non-academic teaching hospital in the Netherlands. Patients were included if they were between 18 and 80 years old, underwent elective minimal invasive colonic resection with anastomosis, had a ASA-score of I or II, fully understood the procedure, had a person at home the first 4 days after surgery and lived within 30 min travel radius to the hospital. Exclusion criteria were cT4 tumours, multi-visceral resections, insulin-dependent diabetes, anti-coagulants which required perioperative bridging, and perioperative complications. Patients followed a pathway with discharge within 24 h postoperatively and were monitored by a tele-monitoring smartphone application after discharge.

RESULTS

Thirty patients were included and twenty-one patients (70%) fulfilled discharge criteria within 24 h after surgery. Six (20%) patients were readmitted within 30 days. Complications occurred in six (20%) patients, which was classified as Clavien-Dindo ≥ 3 complication in one (3%) patient. Patients and health care provider satisfaction was high.

CONCLUSION

Findings of this study support the feasibility and safety of an early discharge protocol with tele-monitoring after minimal invasive colonic resection. Satisfaction of patients and health care providers was high.

Ambulatory Surgery Ensemble: Predicting Adult and Pediatric Same-Day Surgery Cases Across Specialties

Objective

To develop an ensemble model using case-posting data to predict which patients could be discharged on the day of surgery.

Background

Few models have predicted which surgeries are appropriate for day cases. Increasing the ratio of ambulatory surgeries can decrease costs and inpatient bed utilization while improving resource utilization.

Methods

Adult and pediatric patients undergoing elective surgery with any surgical specialty in a multisite academic health system from January 2021 to December 2023 were included in this retrospective study. We used surgical case data available at the time of case posting and created 3 gradient-boosting decision tree classification models to predict case length (CL) less than 6 hours, postoperative length of stay (LOS) less than 6 hours, and home discharge disposition (DD). The models were used to develop an ambulatory surgery ensemble (ASE) model to predict same-day surgery (SDS) cases.

Results

The ASE achieved an area under the receiver operating characteristic curve of 0.95 and an average precision of 0.96. In total, 139,593 cases were included, 48,464 of which were in 2023 and were used for model validation. These methods identified that up to 20% of inpatient cases could be moved to SDS and identified which specialties, procedures, and surgeons had the most opportunity to transition cases.

Conclusions

An ensemble model can predict CL, LOS, and DD for elective cases across multiple services and locations at the time of case posting. While limited in its inclusion of patient factors, this model can systematically facilitate clinical operations such as strategic planning, surgical block time, and case scheduling.

A German's Perspective on the Way toward Ambulatory Laparoscopic Cholecystectomy: A Postoperative Questionnaire

Introduction

Ambulatory surgeries are on the rise in recent years and can offer benefits to patients as well as healthcare providers. Laparoscopic cholecystectomy is one of the procedures commonly done in an ambulatory setting, in some European countries. This study aims to gather patients' perceptions towards ambulatory cholecystectomy after undergoing laparoscopic cholecystectomy in an inpatient setting.

Methods

A total of 300 patients from two different hospitals in Germany received a postoperative questionnaire aimed at evaluating their willingness to undergo an ambulatory surgery. Surgeries were performed between January 1, 2017, and July 11, 2018. Operation setting (acute vs. elective), ASA classification, length of hospital stay, age, sex, living situation and location (city vs. rural), as well as status of employment were documented.

Results

Overall, 23% of patients reported considering ambulatory laparoscopic cholecystectomy (ALC), while 77% rejected an ALC. Objections included fear of complications (69%), anticipated pain (65%), concerns about their living situation/home care (21%), other reasons (8%), nausea and vomiting (3.4%). Baseline characteristics of the participants provided no statistical significance on willingness to undergo ALC: acute versus elective (p = 0.22), ASA classification (p = 0.77), age ≥65 years versus <65 years (p = 0.60), gender (p = 0.07), living situation (p = 0.49), location (p = 0.15).

Conclusion

There is a willingness for ALC, albeit still limited. Chosen criteria did not show a significant association for positive perception of ALC.

Minimally invasive hysterectomy same-day discharge: systematic review and meta-analysis of predictors

PURPOSE

Same-day discharge (SDD) is increasingly prevalent following minimally invasive hysterectomy (MIH). However, consensus guidelines for selecting SDD eligibility criteria for MIH remain unexplored. This study aims to identify predictive factors for non-SDD following MIH (registered in PROSPERO CRD42022350373).

METHODS

PubMed, EMBASE, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials. All original studies that involve patients who were discharged on the same day are compared with those who were not (not failure to discharge / not intended to discharge). Categorical and continuous variables were reported as risk ratios with 95% confidence intervals and weighted mean differences with 95% CIs, respectively. Heterogeneity among the included studies was assessed using the I2 statistics. We conducted sensitivity analysis to identify the reason(s) for this heterogeneity.

RESULTS

Ten studies (59,589 patients) were included, with a mean SDD rate of 20.28%. The predictors of overnight observation included factors such as American Society of Anesthesiologists classification (ASA) > II (P = .02; I2 = 92%), increased estimated blood loss (EBL) (P < 0.00001; I2 = 87%), surgeries starting later in the day (P < 0.00, I2 = 15%), and longer operation times (P = .002; I2 = 96%). In sensitivity and subgroup analyses, uterus weight emerged as a potential factor (P < 0.00; I2 = 50%), while the results concerning ASA, uterine weight, and EBL appeared to be homogeneous. However, the operation time remained heterogeneous.

CONCLUSION

These factors could assist surgeons in the decision-making process regarding the performance of SDD subsequent to MIH procedures for patients.

[Outpatient cholecystectomy as the next step? : Discussion and possible criteria in the selection of patients]

BACKGROUND

While laparoscopic cholecystectomy has largely been performed in an outpatient setting in some countries for years, in Germany it is still generally performed on an inpatient basis; however, with the progressive ambitions for more outpatient treatment within the German healthcare system, laparoscopic cholecystectomy will (have to) increasingly be performed on an outpatient basis in the upcoming years.

AIM OF THE WORK

Presentation of the current framework conditions and the potential for outpatient performance of laparoscopic cholecystectomy in Germany. Presentation and discussion on the current state of knowledge regarding patient selection, treatment pathways and safety of outpatient laparoscopic cholecystectomy.

RESULTS

The potential for outpatient management of laparoscopic cholecystectomy in Germany is high. Based on the current literature, there are no safety concerns regarding outpatient performance of laparoscopic cholecystectomy in selected patients.

CONCLUSION

Outpatient management of laparoscopic cholecystectomy is inevitably heading our way in the next years. The key to successful change will be comprehensive patient information, patient selection and structured outpatient treatment pathways.

Comparative study of ambulatory versus inpatient laparoscopic cholecystectomy in Thailand: Assessing effectiveness and safety with a propensity score matched analysis

Backgrounds/Aims

Ambulatory laparoscopic cholecystectomy (LC) is increasingly recognized for its advantages over the inpatient approach, which advantages include cost-effectiveness and faster recovery. However, its acceptance is limited by patient concerns regarding safety, and the potential for postoperative complications. The study aims to compare the operative and postoperative outcomes of ambulatory LC versus inpatient LC, specifically addressing patient hesitations related to early discharge.

Methods

In a retrospective analysis, patients who underwent LC were divided into ambulatory or inpatient groups based on American Society of Anesthesiologists (ASA) classification, age, and the availability of postoperative care. Propensity score matching was utilized to ensure comparability between the groups. Data collection focused on demographic information, perioperative data, and postoperative follow-up results to identify the safety of both approaches.

Results

The study included a cohort of 220 patients undergoing LC, of which 48 in each group matched post-propensity score matching. The matched analysis indicated that ambulatory LC patients seem to experience shorter operative times and reduced blood loss, but these differences were not statistically significant (35 minutes vs. 46 minutes, p-value = 0.18; and 8.5 mL vs. 23 mL, p-value = 0.14, respectively). There were no significant differences in complication rates or readmission frequencies, compared to the inpatient cohort.

Conclusions

Ambulatory LC does not compromise safety or efficacy, compared to traditional inpatient procedures. The findings suggest that ambulatory LC could be more widely adopted, with appropriate patient education and selection criteria, to alleviate concerns and increase patient acceptance.

Development of a prospective biliary dashboard to compare performance and surgical cost

BACKGROUND

Transparency around surgeon level data may align healthcare delivery with quality care for patients. Biliary surgery includes numerous procedures performed by both general surgeons and subspecialists alike. Cholecystectomy is a common surgical procedure and an optimal cohort to measure quality outcomes within a healthcare system.

METHODS

Data were collected for 5084 biliary operations performed by 68 surgeons in 11 surgical divisions in a health system including a tertiary academic hospital, two regional community hospitals, and two ambulatory surgery centers. A privacy protected dashboard was developed to compare surgeon performance and cost between July 2018 and June 2022. A sample cohort of patients ≥ 18 years who underwent cholecystectomy were compared by operative time, cost, and 30-day outcomes.

RESULTS

Over 4 years, 4568 cholecystectomy procedures were performed by 57 surgeons. Operations were done by 57 surgeons in four divisions and included 3846 (84.2%) laparoscopic cholecystectomies, 601 (13.2%) laparoscopic cholecystectomies with cholangiogram, and 121 (2.6%) open cholecystectomies. Patients were admitted from the emergency room in 2179 (47.7%) cases while 2389 (52.3%) cases were performed in the ambulatory setting. Individual surgeons were compared to peers for volume, intraoperative data, cost, and outcomes. Cost was lowest at ambulatory surgery centers, yet only 4.2% of elective procedures were performed at these facilities. Prepackaged kits with indocyanine green were more expensive than cholangiograms that used iodinated contrast. The rate of emergency department visits was lowest when cases were performed at ambulatory surgery centers.

CONCLUSION

Data generated from clinical dashboards can inform surgeons as to how they compare to peers regarding quality metrics such as cost, time, and complications. In turn, this may guide strategies to standardize care, optimize efficiency, provide cost savings, and improve outcomes for cholecystectomy procedures. Future application of clinical dashboards can assist surgeons and administrators to define value-based care.

Implementing an outpatient surgical management in moderated-high risk patients with groin hernia repair

PURPOSE

There is a growing trend to expand Ambulatory Surgery (AS) criteria in abdominal wall surgery. No Admission (NOADS) circuit. The present study aimed to assess the impact of classification criteria on postoperative results and hospital stays in a NOADS versus a conventional admission circuit to throw some light on surgical circuit inclusion.

METHODS

A retrospective analysis of a prospective;y maintained database was performed comparing groin hernia's interventions in a NOADS vs Admission circuit in our center in 2018-2021. A multiple regression predictive model followed by a retrospective retest were dessigned to assess the impact of each criterion on hospital stay. In total, 743 patients were included, 399 in the Admission circuit (ADC) and 344 in NOADS circuit (NOADS).

RESULTS

There were no statistical differences in complication or readmission rates (p = 0.343 and p = 0.563), nevertheless, a shorter hospital stay was observed in NOADS (p = 0.000). A hierarchical multiple regression predictive model proposed two opposite scenarios. The best scenario, not likely to need admission, was a female patient operated via the laparoscopic approach of a unilateral primary hernia (Estimated Postoperative Stay: 0.049 days). The worst scenario, likely to need admission, was a male patient operated via the open approach of a bilateral and recurrent hernia (Estimated Postoperative Stay: 1.505 Days).

CONCLUSION

Groin hernia patients could safely benefit from a No Admission (NOADS) circuit. Our model could be useful for surgical circuit decision-making, especially for best/worst scenarios.

Enhanced recovery protocols for ambulatory surgery

INTRODUCTION

In the United States, ambulatory surgeries account for up to 87% of all surgical procedures. (1) It was estimated that 19.2 million ambulatory surgeries were performed in 2018 (https://www.hcup-us.ahrq.gov/reports/statbriefs/sb287-Ambulatory-Surgery-Overview-2019.pdf). Cataract procedures and musculoskeletal surgeries are the most common surgical interventions performed in ambulatory centers. However, more complex surgical interventions, such as sleeve gastrectomies, oncological, and spine surgeries, and even arthroplasties are routinely performed as day cases or in a model of an ambulatory extended recovery. (2-5) The ambulatory surgery centers industry has grown since 2017 by 1.1% per year and reached a market size of $31.2 billion. According to the Ambulatory Surgery Center Association, there is a potential to save $57.6 billion in Medicare costs over the next decade (https://www.ibisworld.com/industry-statistics/market-size/ambulatory-surgery-centers-united-states/). These data suggest an expected rise in the volume of ambulatory (same day) or extended ambulatory (23 h) surgeries in coming years. Similar increases are also observed in other countries. For example, 75% of elective surgeries are performed as same-day surgery in the United Kingdom. (6) To reduce costs and improve the quality of care after those more complex procedures, ambulatory surgery centers have started implementing patient-centered, high-quality, value-based practices. To achieve those goals, Enhanced Recovery After Surgery (ERAS) protocols have been implemented to reduce the length of stay, decrease costs, increase patients' satisfaction, and transform clinical practices. The ERAS fundamentals for ambulatory surgery are based on five pillars, including (1) preoperative patient counseling, education, and optimization; (2) multimodal and opioid-sparing analgesia; (3) nausea and vomiting, wound infection, and venous thromboembolism prophylaxis; (4) maintenance of euvolemia; and (5) encouragement of early mobility. Those pillars rely on interdisciplinary teamwork led by anesthesiologists, surgery-specific workgroups, and safety culture. (2) Research shows that a team of ambulatory anesthesiologists is crucial in improving postoperative nausea and vomiting (PONV) and pain control. (7) This review will summarize the current evidence on the elements and clinical importance of implementing ERAS protocol for ambulatory surgery.

Gallbladder wall thickness adversely impacts the surgical outcome

Backgrounds/Aims

To evaluate surgical outcomes of patients with gallbladder wall thickness (GBWT) > 5 mm.

Methods

Patients who underwent cholecystectomy were classified into two groups according to their GBWT status (GBWT+ vs. GBWT-).

Results

Among 1,211 patients who underwent cholecystectomy, GBWT+ was seen in 177 (14.6%). The GBWT+ group was significantly older with more males, higher ASA score, higher alkaline phosphatase level, higher international normalized ratio, and lower albumin level than the GBWT- group. On ultrasound, GBWT+ patients had larger stone size, more pericholecystic fluid, more common bile duct stone, and more biliary pancreatitis. Compared with the GBWT- group, the GBWT+ group had more urgent surgeries (12.4% vs. 3.2%, p = 0.001), higher conversion rate (4.5% vs. 0.3%, p = 0.001), prolonged operative time (67 ± 38 vs. 54 ± 29 min; p = 0.001), more bleeding (3.4% vs. 0.5%, p = 0.002), and more need of drain (21.5% vs. 10.5%, p = 0.001). By multivariate analysis, factors associated with increased length of hospital stay were GBWT+ (HR: 1.97, 95% CI: 1.19-3.25, p = 0.008), urgent surgery (HR: 10.2, 95% CI: 4.07-25.92, p = 0.001), prolonged surgery (HR: 1.01, 95% CI: 1.0-1.02, p = 0.001), and postoperative drain (HR: 11.3, 95% CI: 6.40-20.0, p = 0.001).

Conclusions

Variables such as GBWT ≥ 5 mm, urgent prolonged operation, and postoperative drains are independent predictors of extended hospital stay. GBWT+ patients are twice likely to stay in hospital for more than 72 hours and more prone to develop complications than GBWT- patients.

Statistical models to preoperatively predict operative difficulty in laparoscopic cholecystectomy: A systematic review

BACKGROUND

Laparoscopic cholecystectomy operative difficulty is highly variable and influences outcomes. This systematic review analyzes the performance and clinical value of statistical models to preoperatively predict laparoscopic cholecystectomy operative difficulty.

METHODS

PRISMA guidelines were followed. PubMed, Embase, and the Cochrane Library were searched until June 2020. Primary studies developing or validating preoperative models predicting laparoscopic cholecystectomy operative difficulty in cohorts of >100 patients were included. Studies not reporting performance metrics or enough information for clinical implementation were excluded. Data were extracted according to CHARMS, and study quality was assessed using the PROBAST tool.

RESULTS

In total, 2,654 articles were identified, and 22 met eligibility criteria. Eighteen were model development, whereas 4 were validation studies. Eighteen studies were at high risk of bias. However, 11 studies showed low concern for applicability. Identified models predict 9 definitions of laparoscopic cholecystectomy operative difficulty, the most common being conversion to open surgery and operating time. The most validated models predict an intraoperative difficulty scale and procedures >90 minutes with an area under the curve of >0.70 and >0.76, respectively. Commonly used predictors include demographic variables such as age and gender (9/18 models) and ultrasound findings such as gallbladder wall thickness (11/18). Clinical implementation was never studied.

CONCLUSION

There is a longstanding interest in estimating laparoscopic cholecystectomy operative difficulty. Models to preoperatively predict laparoscopic cholecystectomy operative difficulty have generally good performance and seem applicable. However, an unambiguous definition of operative difficulty, validations, and clinical studies are needed to implement patients' stratification in laparoscopic cholecystectomy.
