Enhanced recovery after surgery for sleeve gastrectomies: improved patient outcomes

A retrospective cohort study on enhanced recovery after surgery (ERAS) in patients with diabetic foot ulcer

Enhanced recovery after surgery (ERAS) has been successfully integrated into a diverse array of surgical fields to improve the quality and efficacy of treatment intervention. Nonetheless, the application of the ERAS protocol for patients with diabetic foot ulcer (DFU) subsequent to undergoing surgical procedures has not been previously explored. Therefore, this study aimed to investigate the effect of an enhanced recovery protocol on perioperative outcomes in patients with DFU following surgical procedures. A retrospective analysis was conducted on 112 patients with DFU who underwent surgery between January 2020 and December 2021 at a tertiary referral care center. In total, 57 patients received standard perioperative care (the non-ERAS group), and 55 patients received ERAS care (the ERAS group). The primary outcomes included the length of stay (LOS), wound healing time, patient satisfaction, and costs, serving as the basis for assessing the effectiveness of the two approaches. Secondary outcomes included preoperative anxiety (APAIS score), nutritional status (PG-SGA), pain (NRS score), the incidence of lower-extremity deep vein thrombosis (DVT), the reduction in lower-limb circumference, and the activity of daily living scale (Barthel Index). The ERAS group exhibited significantly shorter LOS (11.36 vs. 26.74 days; P < 0.001) and lower hospital costs (CNY 62,165.27 vs. CNY 118,326.84; P < 0.001), as well as a higher patient satisfaction score and Barthel Index score (P < 0.05). Additionally, we found a lower APAIS score, incidence of DVT, and circumference reduction in lower limbs in the ERAS group compared to the non-ERAS group (P < 0.05). In comparison, the wound healing time, nutritional status, and pain levels of participants in both groups showed no significant difference (P > 0.05). By reducing the LOS and hospital costs, and by minimizing perioperative complications, the ERAS protocol improves the quality and efficacy of treatment intervention in patients with DFU who underwent surgical procedures.Trial registration number: ChiCTR 2200064223 (Registration Date: 30/09/2022).

Auricular Acupressure in Relieving PONV and Promoting Gastrointestinal Function Recovery in Females After Laparoscopic Sleeve Gastrectomy: A Prospective Randomized Controlled Trial

BACKGROUND

The role of current pharmacological treatment after laparoscopic sleeve gastrectomy (LSG) is limited. The incidence of postoperative nausea and vomiting (PONV) after LSG remains high. Auricular acupressure (AA) is believed to relieve PONV after laparoscopic surgeries, but its role in patients with obesity after LSG has yet to be confirmed.

METHODS

Ninety-five female patients who underwent LSG were randomized into two groups: AA combined with conventional anti-nausea medication (AA group, 47 patients) or conventional anti-nausea medication group (control group, 48 patients). Index of nausea and vomiting and retching (INVR) scores, postoperative anti-vomiting medication use, time of first anus exhausting, time of first fluid intake, and time of first to get out of bed were collected within 48 h after surgery.

RESULTS

Demographic data of patients in both groups were balanced and comparable. INVR score (F = 7.505, P = 0.007), vomiting score (F = 11.903, P = 0.001), and retching score (F = 12.098, P = 0.001) were significantly lower in the AA group than that in the control group within 48 h postoperatively. Use of metoclopramide was significantly less in the AA group than in the control group (4.7 [5.5]) vs. 8.8 [7.6], P = 0.004); time to first anus exhausting was significantly less in the AA group than in the control group (17.50 [6.00] vs. 20.42 [8.62], P = 0.020).

CONCLUSIONS

AA combined with conventional anti-vomiting agents can alleviate PONV in female patients after LSG, and AA can promote gastrointestinal exhaustion.

The current status and challenges of perioperative management of patients with a BMI of greater than or equal to 50 kg/m 2 undergoing bariatric surgery in China: a multicenter cross-sectional study

BACKGROUND

Performing bariatric surgery on patients with a BMI of over 50 kg/m 2 is challenging. This study aimed to explore the status and challenges related to the perioperative management of such patients in China.

MATERIALS AND METHODS

A prospective survey was designed to investigate the perioperative management of patients with a BMI of greater than or equal to 50 kg/m 2 undergoing bariatric surgery in China. The questionnaire of our survey included general information, preoperative management measures, surgical procedures performed, technical details regarding anaesthesia, and postoperative management measures. A response from only one attending physician per bariatric centre was accepted.

RESULTS

Physicians from a total of 101 hospitals responded to the questionnaire, and the questionnaire data from 98 hospitals were complete. These centres had completed a total of 44 702 bariatric surgeries since the launch of such surgery to December 2021. A total of 3280 patients had a BMI exceeding 50 kg/m 2 . The preferred surgical procedures for patients with super obesity were sleeve gastrectomy by 62 centres, Roux-en-Y gastric bypass by 11 centres, sleeve gastrectomy plus jejunojejunal bypass by 19 centres, one anastomosis gastric bypass by 1 centre, and duodenal switch by 1 centre. The most worrying issues were cardiopulmonary failure and difficulty in extubation. 91 centres believed that preoperative weight loss was beneficial. A low-calorie diet was the specific measure mainly implemented, only three centres considered using intragastric balloon placement. Postoperative management measures varied greatly.

CONCLUSION

Bariatric surgery has seen rapid development. Chinese physicians show significant differences regarding the perioperative management for patients with a BMI of over 50 kg/m 2 . The perioperative risks of these patients remain relatively high, making further development of clinical pathways is necessary.

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.

Opioid Analgesics after Bariatric Surgery: A Scoping Review to Evaluate Physiological Risk Factors for Opioid-Related Harm

The persisting use of opioids following bariatric surgery has emerged as a prevalent complication, heightening the probability of opioid-related harm (ORM), such as opioid-related fatalities and prescription opioid use disorder (OUD). A comprehensive review of PubMed literature from 1990 to 2023 was conducted to pinpoint physiological influences on postoperative ORM. As a result, we found that patients undertaking bariatric operations often exhibit an inherently higher risk for substance use disorders, likely attributable to genetic predisposition and related neurobiological changes that engender obesity and addiction-like tendencies. Furthermore, chronic pain is a common post-bariatric surgery complaint, and the surgical type impacts opioid needs, with increased long-term opioid use after surgeries. Additionally, the subjective nature of pain perception in patients with obesity can distort pain reporting and the corresponding opioid prescription both before and after surgery. Furthermore, the postoperative alterations to the gastrointestinal structure can affect the microbiome and opioid absorption rates, resulting in fluctuating systemic exposure to orally ingested opioids. The prospect of ORM development post-bariatric surgery appears amplified due to a preexisting susceptibility to addictive habits, surgically induced pain, modified gut-brain interaction and pain management and the changed pharmacokinetics post-surgery. Further research is warranted to clarify these potential risk variables for ORM, specifically OUD, in the bariatric population.

Efficacy and safety of enhanced recovery after surgery protocol on minimally invasive bariatric surgery: a meta-analysis

BACKGROUND

Enhanced recovery after surgery (ERAS), a multidisciplinary and multimodal perioperative care protocol, has been widely used in several surgical fields. However, the effect of this care protocol on patients receiving minimally invasive bariatric surgery remains unclear. This meta-analysis compared the clinical outcomes of the ERAS protocol and standard care (SC) in patients who underwent minimally invasive bariatric surgery.

MATERIAL AND METHODS

PubMed, Web of Science, Cochrane Library, and Embase databases were systematically searched to identify literature reporting the effects of the ERAS protocol on clinical outcomes in patients undergoing minimally invasive bariatric surgery. All the articles published until 01 October 2022, were searched, followed by data extraction of the included literature and independent quality assessment. Then, pooled mean difference (MD) and odds ratio with a 95% CI were calculated by either a random-effects or fixed-effects model.

RESULTS

Overall, 21 studies involving 10 764 patients were included in the final analysis. With the ERAS protocol, the length of hospitalization (MD: -1.02, 95% CI: -1.41 to -0.64, P <0.00001), hospitalization costs (MD: -678.50, 95% CI: -1196.39 to -160.60, P =0.01), and the incidence of 30-day readmission (odds ratio =0.78, 95% CI: 0.63-0.97, P =0.02) were significantly reduced. The incidences of overall complications, major complications (Clavien-Dindo grade ≥3), postoperative nausea and vomiting, intra-abdominal bleeding, anastomotic leak, incisional infection, reoperation, and mortality did not differ significantly between the ERAS and SC groups.

CONCLUSIONS

The current meta-analysis indicated that the ERAS protocol could be safely and feasibly implemented in the perioperative management of patients receiving minimally invasive bariatric surgery. Compared with SC, this protocol leads to significantly shorter hospitalization lengths, lower 30-day readmission rate, and hospitalization costs. However, no differences were observed in postoperative complications and mortality.

Application of enhanced recovery after surgery in perioperative patients undergoing laparoscopic surgery for gastric cancer: A meta-analysis

BACKGROUND

To analyze the effect of enhanced recovery after surgery (ERAS) in perioperative patients undergoing laparoscopic surgery for gastric cancer (GC).

METHODS

We searched the literature databases of PubMed (https://pubmed.ncbi.nlm.nih.gov/) and Web of Science (https://www.webofscience.com/) for studies related to ERAS and laparoscopic surgery for GC from their inception till October 2022, and the retrieved articles were further screened for analysis. The literature quality was evaluated based on the Cochrane risk of bias tool. The endpoints included the first postoperative exhaust time, first postoperative bowel movement, length of stay, complications and hospitalization expenses. The meta-analysis was performed using RevMan 5.4 software.

RESULTS

11 studies were included, involving 2039 patients. Meta-analysis showed that the first postoperative exhaust and bowel movement were earlier and the length of stay was shorter in the experimental group (e.g.,) than in the control group (CG) (P < .05). Moreover, a lower incidence of complications and markedly reduced hospitalization expenses were determined in for example (P < .05). Due to the heterogeneity in the comparison of indicators such as the first postoperative exhaust and bowel movement across articles, a funnel plot was drawn for observations. The plot was found to be basically symmetrical, indicating small results bias and reliable reference significance of our findings.

CONCLUSION

ERAS for perioperative patients undergoing laparoscopic surgery for GC can effectively shorten the postoperative rehabilitation cycle of patients, improve surgical safety and reduce treatment costs.

Decreased ER visits and readmissions after implementation of a standardized perioperative toolkit for children with IBD

BACKGROUND

Pediatric inflammatory bowel disease (IBD) carries significant morbidity and requires extensive medical and often surgical intervention. The aim of this study was to evaluate the impact of a dedicated Multidisciplinary clinic on the outcomes of children with IBD.

METHODS

A retrospective review of a prospective database, established to track quality and outcomes of children undergoing an abdominal operation for IBD, was performed. Children who were managed before (09/2017-03/2019) and after (04/2019-06/2020) establishment of the multidisciplinary clinic were examined. The clinic instituted several care process protocols including early recovery (ERAS) and garnered additional resources for patients (wound ostomy, nutrition, social work, etc.) Primary outcomes were unanticipated return to the operating room, length of stay, ER visits within 30 days of surgery and hospital readmissions within 30 days of surgery.

RESULTS

We identified 41 children who underwent a total of 80 major abdominal operations; 46.3% of procedures occurred before and 53.7% occurred after instituting our clinic. There were no notable changes in disease distribution (e.g., ulcerative colitis vs. Crohn's), disease severity, medication exposure, or case urgency (elective vs. emergent). ER visits within 30 days of surgery decreased (4 (9.3%) vs. 10 (27%), p = 0.04) as did readmissions within 30 days of surgery (1 (2.3%) vs. 9 (24.3%), p = 0.005).

CONCLUSIONS

Implementation of a dedicated multidisciplinary clinic for IBD and its attendant focus on protocols and appropriate use of adjunctive resources was associated with decreased emergency department visits and hospital readmissions in the post-operative setting.

The role of ultrasonography in anesthesia for bariatric surgery

Bariatric surgeries are effective long-term management for morbid obesity with its adverse sequelae. Anesthesia of bariatric surgeries poses unique challenges for the anesthesiologist in every step starting with vascular access till tracheal extubation. The usage of ultrasound in anesthesia is becoming more prevalent with a variety of benefits, especially in the obese population. Ultrasound is successfully used for obtaining vascular access, with more than 15 million catheters placed in the United States alone. Ultrasound can also be used to predict difficult intubation, as it can confirm the tracheal intubation and assess the gastric content to prevent pulmonary aspiration. Ultrasound is also used in the management of mechanically ventilated patients to monitor lung aeration and to identify respiratory complications during positive pressure ventilation. Moreover, intraoperative echocardiography helps to discover the pulmonary embolism and guides the fluid therapy. Finally, ultrasound can be used to perform neuraxial and fascial plane block with a less overall time of the procedures and minimal complications. The wide use of ultrasound in bariatric anesthesia reflects the learning curve of the anesthesiologists and their mounting efforts to provide safe anesthesia utilizing the updated technology. In this review, we highlight the role of ultrasonography in anesthesia of bariatric surgery and discuss the recent guidelines.
