Strategies and recommendations for the management of gastrointestinal surgery during the COVID-19 pandemic: experience shared by Chinese surgeons

Bio-Inspired Fractal Robust Hydrogel Catheter for Intra-Abdominal Sepsis Management

To deal with intra-abdominal sepsis, one of the major global causes of death in hospitalized patients, efficient abscess drainage is crucial. Despite decades of advances, traditional catheters have demonstrated poor drainage and absorption properties due to their simple tubular structures and their dense nonporous surface. Herein, inspired by porous sponges and fractal roots, a multifaceted hydrogel catheter with effective drainage, absorptive, and robust properties, is presented. Its unique fractal structures provide extensive internal branching and a high specific surface area for effective drainage, while the hierarchical porous structures provide a wide range of absorption capabilities. Additionally, its distinctive multi-interpenetration network maintains robust and appropriate mechanical properties, even after absorption multiple times of liquid and mechanical disturbance, allowing for intact removal from the abdominal cavity without harm to the animal in vivo. Besides, the loaded antimicrobial peptides are capable of being released in situ to inhibit the potential for infections. In vivo experiments have demonstrated that this hydrogel catheter efficiently removes lethal abscesses and improves survival. It is believed that this innovative and practical catheter will create a future precedent for hydrogel drainage devices for more effective management of intra-abdominal sepsis.

COVID-19 pandemic: is it time for shared surgical guidelines? A systematic review of the literature

INTRODUCTION

The recent COrona Virus Disease 2019 (COVID-19) pandemic caused a massive disruption of surgical activity and after a year from its first outbreak surgeons still struggle to keep their regular activity coexisting with the virus exhausting requests of healthcare resources. The aim of this paper is to offer a comprehensive overview of the most important recommendations by the International Guidelines about general surgery, and possibly to invite building common shared guidelines to preserve the potential to provide surgical assistance despite the pandemic.

EVIDENCE ACQUISITION

This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. PubMed, Embase, Cochrane and Web of Science databases were searched.

EVIDENCE SYNTHESIS

The searches revealed a total of 18579 articles published up to the end of February 2021. Five articles published between March and May 2020, were included in the present study: Guidelines from The European Society of Trauma and Emergency Surgery (ESTES), The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and The European Association for Endoscopic Surgeons (EAES), The Endoscopic and Laparoscopic Surgeons of Asia (ELSA), The European Hernia Society (EHS) and The International Organization for the Study of Inflammatory Bowel Disease (IOS-IBD).

CONCLUSIONS

In the likely scenario that the SARS-CoV-2 pandemic will become an endemic chronic problem, we should not be forced to choose between COVID-19 or surgery in the future and find a way to make both coexisting.

Acute Mesenteric Ischemia in a COVID-19 Patient: Delay in Referral and Recommendation for Surgery

Coronavirus (COVID-19) is more common with symptoms such as fever, dry cough, and shortness of breath. However, it may be associated with COVID-19-induced gastrointestinal (GI) symptoms including acute mesenteric ischemia (AMI). These conditions make the diagnosis of AMI challenging. Timely referral with correct diagnosis and attention to the uncommon symptoms of COVID-19 can play an important role in the management and treatment of AMI in COVID-19 patients. We present a patient with AMI due to thrombotic complications of COVID-19, who referred to the hospital too late and ignored the recommendation for abdominal surgery.

Psychosocio-economic impacts of COVID-19 on gastroenterology and endoscopy practice

Beyond posing a major health crisis, the COVID-19 pandemic has inflicted profound psychological, social, and economic impacts on populations worldwide. Mass quarantines and social isolation have affected the mental health of the wider population, exacerbating other stressors, including fear of the virus and its repercussions, general uncertainty, and financial insecurity. The pandemic has challenged the broader delivery of healthcare--ranging from the need to triage limited hospital resources to balancing risk mitigation with maintaining medical care. Specific to gastroenterology, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has not only been associated with complicating extant medical conditions of the gastrointestinal (GI) tract, but has also forced a shift in the practice of gastroenterology by patients, families, and healthcare providers alike. The gastroenterology field has been required to adapt its practices to minimize the possibility of viral spread while still upholding patient care. Healthcare practitioners in GI have helped to treat COVID-19 patients, stratified inpatient and outpatient visits and procedures, and shifted to telemedicine. Still, as is the case with much of the general population, healthcare providers working in GI practice or endoscopy have faced personal and professional stressors, mental health difficulties, social isolation, financial pressures, and familial burdens--all of which can take a toll on practitioners and, by extension, the provision of GI care overall. This article will highlight how the COVID-19 pandemic has affected the psychological wellbeing, social engagement, and economic conditions of the public, healthcare providers, and GI professionals specifically. Recommendations for strategies that can continue GI services while maintaining safety for both caregivers and patients are put forth to help uphold critical GI care during this worldwide crisis.

The COVID-19 pandemic: impact on surgical departments of non-university hospitals

Background

During the first wave of the COVID-19 pandemic, German health care centres were restructured for the treatment of COVID-19 patients. This was accompanied by the suspension of the surgical programme. The aim of the survey was to determine the effects of COVID-19 on surgical care in non-university hospitals in Germany.

Methods

This cross-sectional study was based on an anonymous online survey, which was accessible from April 24th to May 10th, 2020 for surgeons of the Konvent der leitenden Krankenhauschirurgen (Convention of leading Hospital Surgeons) in Germany. The analysis comprised of 22.8% (n = 148/649) completed surveys.

Results

Communication and cooperation with authorities, hospital administration and other departments were largely considered sufficient. In the early phase of the COVID-19 pandemic, 28.4% (n = 42/148) of the respondents complained about a short supply of protective equipment available for the hospital staff. 7.4% (n = 11/148) of the participants stated that emergency operations had to be postponed or rescheduled. A decreased quantity of emergency surgical procedures and a decreased number of surgical emergency patients treated in the emergency room was reported in 43.9% (n = 65/148) and 63.5% (n = 94/148), respectively. Consultation and treatment of oncological patients in the outpatient clinic was decreased in 54.1% (n = 80/148) of the surveyed hospitals. To increase the capacity for COVID-19 patients, a reduction of bed and operating room occupancy of 50.8 ± 19.3% and 54.2 ± 19.1% were reported, respectively. Therefore, 90.5% (n = 134/148) of all participants expected a loss of revenue of 28.2 ± 12.9% in 2020.

Conclusion

The first wave of the COVID-19 pandemic had a significant impact on surgical care in Germany. The reduction in the bed and the operating room capacity may have lead to considerable delays in urgent and semi-elective surgical interventions. In addition to the risk of worsening patient care, we anticipate severe financial damage to the clinics in 2020 and beyond. National and supranational planning is urgently needed to ensure the surgical care of patients during the ongoing COVID-19 pandemic.
