Cyclic vomiting syndrome (CVS) is a chronic digestive disorder characterized by recurrent episodes of severe nausea and vomiting. The perioperative management of patients with CVS undergoing general anesthesia is challenging, especially when combined with obesity. This case report describes the successful management of a patient with CVS and obesity who underwent dental surgery under general anesthesia. A 21-year-old woman with CVS, obesity (body mass index, 35), and intellectual disability was scheduled for tooth extraction and composite resin restoration under general anesthesia. The patient was diagnosed with CVS at the age of 20 years with frequent vomiting attacks requiring hospitalization. Surgery was scheduled during the CVS remission to reduce the risk of perioperative vomiting. Preoperative laboratory test results were normal, including serum adrenocorticotropic hormone (ACTH), anti-diuretic hormone (ADH), and cortisol levels. General anesthesia was induced using remifentanil and propofol. Nasal endotracheal intubation was performed after rocuronium administration. Local anesthesia (2% lidocaine with 1:80,000 epinephrine) was used for all dental procedures. Postoperatively, midazolam was administered to control agitation. No postoperative vomiting occurred. Serum ACTH, ADH, and cortisol levels showed no significant changes before and after anesthesia, suggesting that hypothalamic-pituitary-adrenal (HPA) axis activation due to surgical stress did not occur. This case highlights the importance of careful perioperative planning and monitoring stress-related hormone levels in patients with CVS or obesity. An anesthetic approach using midazolam may effectively suppress HPA axis activation and prevent postoperative vomiting.

UNASSIGNED: In 2013, Japan established a standardized classification system for categorizing endoscopic sinus surgery (ESS) into types I-V, yet no evaluation has been conducted thereof.
UNASSIGNED: We assessed the ESS trends and status in Japan, focusing on outpatient and inpatient surgeries.
UNASSIGNED: This descriptive retrospective cohort study used Japan\'s National Database of Health Insurance Claims and Specific Health Checkups between 2014 and 2021. The distribution of ESS types I-V and outpatient and inpatient surgeries was analysed, along with age groups and regional differences, focusing on ESS type III.
UNASSIGNED: Overall, 427,813 ESS procedures were performed, with types III and IV being most common. Outpatient ESS type III increased substantially compared to inpatient surgeries. Younger individuals favoured outpatient ESS type III over inpatient surgeries, with substantial regional variations across prefectures.
UNASSIGNED: The adoption of a standardized ESS classification in Japan has facilitated a detailed understanding of surgical trends. The shift toward outpatient surgeries, especially for type III ESS, aligns with global trends toward minimally invasive procedures and reflects changing patient preferences and healthcare delivery practices. Consequently, continuous monitoring and research are crucial for adapting surgical practices to the evolving healthcare needs and patient expectations.

This study was based on the Kano model and rely on the Internet hospital to build a day surgery patient full-process nursing service platform. Based on the Internet hospital\'s HIS system, nursing Yuanzhuo system, patient mobile terminal (WeChat) and other information systems. The platform was designed by following the WHO\'s conceptual framework for developing a scaling-up strategy. It was tested and refined by a pilot in a hospital in China. The full-process care platform for day surgery patients realizes information interconnection and interoperability of patient surgical consultation, surgical inquiries, and postoperative follow-up. It consists of a WeChat applet (client) and an online website (server). Pre-experiment results show that patients are more likely to recommend the hospital\'s day surgery to others. The mHealth-based perioperative full-process nursing service platform for day surgery patients can initially meet the health education needs, surgical consultation needs and follow-up needs of day surgery patients.

To alleviate the medical burden of lung cancer surgery and facilitate the implementation of the national hierarchical diagnosis and treatment policy, it is imperative to establish a hierarchical diagnosis and treatment system for day surgery of lung cancer. Identifying key quality control checkpoints in day surgery of lung cancer is essential to enhance medical quality, ensure safety, and improve the efficiency of medical services. These efforts aim to uphold a safe and well-structured progression of day surgery practices in China. The Chinese Expert Consensus Group on Day Surgery Management of Lung Cancer has convened national experts in relevant fields and integrated the latest research findings from both domestic and international sources to craft the Chinese Expert Consensus on Day Surgery Management of Lung Cancer (2024 Edition). This consensus is founded on the principles of holistic management of lung cancer surgery and comprehensive patient care throughout their medical journey. It encompasses preoperative assessments, anesthesia protocols, surgical procedures, postoperative care, hospital-community collaboration initiatives, and emergency response strategies. The primary objective of this expert consensus is to furnish research assistance and clinical recommendations to advance the practice of day surgery for lung cancer patients in China.

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%).
CONCLUSIONS: 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.

BACKGROUND: Adequate treatment of acute postoperative pain is one of the quality requirements in ambulatory surgery and its suboptimal management is associated with delayed discharge, unplanned admissions and late admissions after home discharge. The aim of the present study was to learn about the organizational strategy for the management of postoperative pain in ambulatory surgery units (ASU) in Spain.
METHODS: A cross-sectional, multicenter study was carried out based on an electronic survey on aspects related to the management of acute postoperative pain in different ASUs in our country.
RESULTS: We recruited 133 ASUs of which 85 responded to the questions on the management of postoperative pain. Of the ASUs that responded, 80% had specific protocols for pain management and 37.6% provided preoperative information on the analgesic plan. The assessment of postoperative pain is carried out in 88.2% of the ASUs in the facility and only 56.5% at home. All ASUs use multimodal analgesia protocols; however, 68.2% report the use of opioids for the treatment of moderate to severe pain. Home invasive analgesia strategies are minimally used by the surveyed ASUs.
CONCLUSIONS: The DUCMA study highlights that the practice of pain treatment in day surgery remains a challenge in our country and is not always in agreement with national guidelines. The results suggest the need to establish strategies to improve clinical practice and homogenize pain management in ambulatory surgery.

BACKGROUND: Day surgery for unicompartmental knee replacement (UKR) could potentially reduce hospital costs. We aimed to measure the impact of introducing a day surgery UKR pathway on mean length of stay (LOS) and costs for the UK NHS, compared to an accelerated inpatient pathway. Secondly, the study aimed to compare the magnitude of costs using three costing approaches: top-down costing; simple micro-costing; and real-world costing.
METHODS: We conducted an observational, before-and-after study of 2,111 UKR patients at one NHS hospital: 1,094 patients followed the day surgery pathway between September 2017 and February 2020; and 1,017 patients followed the accelerated inpatient pathway between September 2013 and February 2016. Top-down costs were estimated using Average NHS Costs. Simple micro-costing used the cost per bed-day. Real-world costs for this centre were estimated by costing actual changes in staffing levels.
RESULTS: 532 (48.5%) patients in the day surgery pathway were discharged on the day of surgery compared with 36 (3.5%) patients in the accelerated inpatient pathway. The day surgery pathway reduced the mean LOS by 2.2 (95% CI: 1.81, 2.53) nights and was associated with an 18% decrease in Average NHS Costs (p < 0.001). Mean savings were £1,429 per patient with the Average NHS Costs approach, £905 per patient with the micro-costing approach, and £577 per patient with the \"real-world\" costing approach. Overall, moving NHS UKR surgeries to a day surgery pathway could save the NHS £8,659,740 per year.
CONCLUSIONS: Day surgery for UKR could produce substantial cost savings for hospitals and the NHS.

This study investigates the interplay between plastic and reconstructive surgery patients and their respective caregivers in the Day Surgery Unit of Policlinico Umberto I, Rome, Italy. Utilizing a dual survey approach, we explored the role in patient safety and the challenges faced by caregivers during the perioperative period. This study, conducted at Policlinico Umberto I, covers all surgical procedures from October to December 2023, encompassing skin cancer removal, fat grafting, scar revisions, hand surgeries, and eyelid surgeries. Patient demographics reflect varying age distributions: 18-39 (4.9%), 40-59 (31.7%), 60-75 (34.1%), and over 76 years (29.3%).

Introduction The prevalence of one-day surgery (also known as same-day surgery or outpatient surgery) has been increasing recently among patients and physicians in many countries due to its benefits. The main benefits of one-day surgery are that the patient is not planned to stay overnight before the surgery and can be discharged on the same day of the surgery. The lower cost to the health system can make these surgeries more favorable for both sides. However, unplanned readmission after such surgeries can happen and this has broad implications for patients, their families, and the healthcare system. Therefore, this study primarily aims to identify the incidence of unexpected hospital readmissions following one-day surgery after discharge among children. The study also aims to identify any significant variables that can be identified with the cases of readmissions to allow for further investigations in future studies Methods This study was done at King Abdullah Specialist Children\'s Hospital in Riyadh, Saudi Arabia. The target population included all pediatric patients who underwent one-day surgeries and were admitted within one week of their discharge from 2017 to 2023 through outpatient clinics and the emergency department. Results The study sample size was 403 patients, with male patients accounting for 241 surgeries (59.8%), and female patients accounting for 162 surgeries (40.1%). The most common American Society of Anesthesiologists (ASA) classification was II, accounting for 169 cases (41.9%). Toddlers and preschoolers (aged 1-6 years) were the age groups with the highest number of patients (n=252, 62.5% combined). Elective surgeries accounted for 382 cases (94.7%). The specialty with the highest number of surgeries was ear, nose, and throat with 284 cases (70.4%) with tonsillectomy with adenoidectomy being the most common surgery with 234 cases (58%). The most common reasons for unplanned readmission were poor oral intake (n=146, 36.2%) and bleeding (n=131, 32.5%). The most common day of readmission was the seventh day in five surgical specialties (45.4%). Conclusion Over the past seven years, 403 patients were readmitted within one week after their one-day surgery at King Abdullah Specialist Children\'s Hospital. Such a situation may cause dissatisfaction with the medical care that the patients were given and eventually may build an untrusted relationship between the patient and the physician. Future investigations should be established to lower such a condition and develop prevention methods to lower its prevalence.
