Abstract
Electrocautery is a commonly used technique in surgical procedures, generating smoke that poses health risks to surgical staff. This study investigates the comparative efficacy of normal surgical masks versus N95 masks in mitigating the harmful effects of electrocautery smoke. Through a systematic review of literature spanning two decades, we explore the causes and effects of electrocautery smoke exposure, including potential long-term inhalation effects. Our findings highlight significant disparities in the protection offered by different masks and underscore the importance of adequate respiratory protection in surgical settings. In addition, we examine the factors influencing the generation and composition of electrocautery smoke, such as the power settings used, the type of tissue being cauterized, and the duration of the procedure. Furthermore, we discuss the potential health risks associated with long-term exposure to electrocautery smoke, including the possibility of respiratory conditions, cardiovascular effects, and carcinogenicity. Our analysis also addresses the importance of implementing appropriate smoke evacuation systems and optimizing operating room ventilation to minimize the concentration of smoke particles in the surgical environment. Overall, this comprehensive analysis provides valuable insights into the impact of electrocautery smoke in surgical settings and the varying levels of protection offered by different masks.

Kumari P, Sainath K, Biswas S, Bellare J. Risk mitigation to healthcare workers against viral and bacterial bioaerosol load in laparoscopic surgical exhaust with a new flow mode in hollow fiber membranes-based filter. JOURNAL OF HAZARDOUS MATERIALS 2024; 461:132517. [PMID: 37757552 DOI: 10.1016/j.jhazmat.2023.132517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 08/25/2023] [Accepted: 09/07/2023] [Indexed: 09/29/2023]
Abstract
Laparoscopy of COVID-19-infected/suspected patients needs to be performed with the utmost care due to the chances of virus carryover through the pneumoperitoneum gas. In this study, polysulfone/polyvinyl-pyrrolidone hollow fiber membranes (HFMs) were fabricated by phase inversion process, and these HFMs were bundled into a module consisting of tortuous, circular-helical arrangement. Further, copper (Cu) and zinc (Zn) nanoparticles (NPs), known to have antimicrobial and antiviral properties, were flow-coated on the lumen side of the HFMs. To test functional efficiency, the modules were challenged with wet aerosol and bioaerosols. Wet aerosol removal efficiency was ∼98%. Bioaerosol-containing bacteria E. coli strain K-12, showed 2.6 log (∼99.8%), and 2.1 log (∼99.3%) removal efficiency for Cu NPs and Zn NPs coated HFMs modules, respectively, and 1.6 log (∼97%) removal for plain (uncoated) HFMs. Bioaerosols containing SARS-CoV-2 surrogate virus (MS2 bacteriophage) showed ∼5-7 log reduction of bacteriophage for plain HFMs, 3.9 log, and 2.3 log reduction for Cu and Zn coated HFMs, respectively. The flow of aerosols entirely through the HFM lumen helps in attaining a low ΔP of < 1 mm Hg, thus rendering its usefulness, particularly for exhausting pneumoperitoneum gases where high upstream pressures could lead to barotrauma. STATEMENT OF ENVIRONMENTAL IMPLICATION: Surgical smoke is generated during minimally invasive surgical (MIS) procedure such as laparoscopy when electrosurgical devices are used to cut any tissues. This smoke is a hazard as it contains toxic volatile compounds, mutagens, carcinogens, bacteria, and virus-laden aerosols. Infection to healthcare professionals through the bioaerosols containing smoke is well reported in literature. The limitation of using hypochlorite and pleated/HEPA filter, led us to design a low pressure drop bioaerosol filter, which can remove smoke, tissue fragments, and COVID-19 virus. It provides a much safer operation theatre environment during MIS procedures as well as in general for bioaerosol removal.

Abstract
OBJECTIVE To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19. METHODS From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21). RESULTS A total of 1965 patients (A n = 1517, B n = 52, C n = 396) were included. The A group had significantly more previous SDD compared to the two other groups (p = 0.007), especially complicated (p = 0.0004). The rate of peritonitis was significantly higher in the B (46.1%) and C (38.4%) groups compared to the A group (31.7%) (p = 0.034 and p = 0.014). As regards surgical treatment, Hartmann's procedure was more often performed in the B group (44.2%, vs A 25.5% and C 26.8%, p = 0.01). Mortality at 90 days was significantly higher in the B group (9.6%, vs A 4% and C 6.3%, p = 0.034). This difference was also significant between the A and B groups (p = 0.048), as well as between the A and C groups (p = 0.05). There was no significant difference between the three groups in terms of postoperative morbidity. CONCLUSION This study shows that the management of SDD was impacted by COVID-19 at CR, but also after and until September 2021, both on the initial clinical presentation and on postoperative mortality.

Abstract
The acquisition of basic surgical skills is a key component of medical education and trainees in laparoscopic surgery typically begin developing their skills using simulation box trainers. However, despite the advantages of simulation surgical training, access can be difficult for many trainees. One technique that has shown promise to enhance the deliberate practice of motor skills is transcranial electric stimulation (tES). The purpose of this study was to assess the impact of transcranial direct current stimulation (tDCS) on training induced improvements and retention of traditional time and kinematic based laparoscopic surgical skill metrics. Forty-nine medical students were randomly allocated to a neurostimulation or sham group and completed 5 training sessions of a bead transfer and threading laparoscopic task. Participants in both the sham and stimulation groups significantly improved their time and kinematic performance on both tasks following training. Although we did find that participants who received M1 tDCS saw greater performance benefits in response to training on a bead transfer task compared to those receiving sham stimulation no effect of neurostimulation was found for the threading task. This finding raises new questions regarding the effect that motor task complexity has on the efficacy of neurostimulation to augment training induced improvement and contributes to a growing body of research investigating the effects of neurostimulation on the sensory-motor performance of laparoscopic surgical skill.

Abstract
Introduction: There is an ongoing concern about the potential infectious risk due to pneumoperitoneal gas leakage from surgical trocars in laparoscopic surgery. We aimed to visually confirm the presence of leakage from trocars and investigate the changes in the leakage scale according to intra-abdominal pressures and trocar types. Material and methods: We established a porcine pneumoperitoneum model and performed experimental forceps manipulation using 5-mm grasping forceps with 12-mm trocars. The gas leakage, if any, was imaged using a Schlieren optical system, which can visualize minute gas flow invisible to the naked eye. For measuring the scale, we calculated the gas leakage velocity and area using image analysis software. Four types of unused and exhausted disposable trocars were compared. Results: Gas leakage was observed from trocars during forceps insertion and removal. Both the gas leakage velocity and area increased as the intra-abdominal pressure increased. Every type of trocar we handled was associated with gas leakage, and exhausted disposable trocars had the largest scale gas leakage. Conclusions: We confirmed gas leakage from trocars during device traffic. The scale of leakage increased with high intra-abdominal pressure and with the use of exhausted trocars. Current protection against gas leakage may not be sufficient and new surgical safety measures and device development may be needed in the future.

Abstract
BACKGROUND COVID-19 pandemic has led to changes in the presentation and treatment of surgical pathologies. Therefore, we aim to describe the influence of the COVID-19 pandemic on the clinical presentation and management of acute appendicitis (AAp) and its surgical outcomes. STUDY DESIGN A multicenter cohort study with prospectively collected databases. Three high-volume centers were included and all patients over 18 years of age who underwent appendectomy for AAp were included. Multiple logistic regression and multinomial logistic regression were performed, and odds ratio, relative risk, and B-coefficient were reported when appropriate, statistical significance was reached with p-values < 0.05. RESULTS 1.468 patients were included (709 in the pre-pandemic group and 759 in the COVID-19 group). Female patients constituted 51.84%. Mean age was 38.13 ± 16.96 years. Mean Alvarado's score was 7.01 ± 1.59 points. Open surgical approach was preferred in 90.12%. Conversion rate of 1.29%. Mortality rate was 0.75%. There was an increase of perforated and localized peritonitis (p 0.01) in the COVID-19 group. Presence of any postoperative complication (p 0.00), requirement of right colectomy and ileostomy (p 0.00), and mortality (p 0.04) were higher in the COVID-19 group. Patients in the pre-pandemic group have a lesser risk of mortality (OR 0.14, p 0.02, 95% CI 0.02-0.81) and a lesser relative risk of having complicated appendicitis (RR 0.68, p 0.00, 95% CI 0.54-0.86). CONCLUSION Complicated appendicitis was an unexpected consequence of the COVID-19 pandemic, due to surgical consultation delay, increased rates of morbidity, associated procedures, and mortality, influencing the clinical course and surgical outcomes of patients with AAp.

Abstract
Introduction While the COVID-19 pandemic is still ongoing, it is even more evident that victims of the pandemic are not only those who contract the virus, but also the countless patients suffering from other serious diseases (i.e., tumor) who have undergone delayed potentially life-saving surgery due to a lack of beds. Like many hospitals, ours also initially blocked all elective oncologic surgery, but these operations were “recovered” and reintegrated in a relatively short time, thanks to the establishment of COVID-free wards and operating rooms with staff dedicated to oncological surgery. In tis context, our aim is to assess whether and how the severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) pandemic has impacted our hepatobiliary surgery unit. Methods From our prospective database, we retrospectively took data from patients undergoing liver surgery in 2018–2019 (pre-COVID) and 2020–2021 (COVID period). Patients admitted to COVID-free wards must necessarily have a negative nasal swab from the previous 24 h. Results Between January 1, 2018, and December 31, 2019 (Group 1), 101 patients were treated; during the pandemic [January 1, 2020, and December 31, 2021 (Group 2)], 126 patients were treated. There was no statistical difference between the groups. The median postoperative hospital stay was 7 days for both groups; 7 patients had major complications (Clavien-Dindo > 3) in Group 1 and 11 in Group 2 (p = 0.795). A total of 4 patients died in Group 1 and 6 during the pandemic (p = 0.754). Tumor burden was significantly greater in Group 2 where nodule size, lymphadenectomy, and extrahepatic disease were significantly greater (p = 0.011, p = 0.004, and p = 0.026, respectively). Conclusion During the COVID pandemic, our HPB unit managed to offer a volume of tertiary-center hepatobiliary surgery without a significant impact in terms of length of stay, morbidity, or mortality despite the increase in tumor burden during the pandemic years.

Abstract
(1) Background: The COVID-19 pandemic put a great burden on national healthcare systems, causing delays and disruptions in the medical care of non-COVID-19 patients. This paper aims to analyze the COVID-19 pandemic impact upon the quality of care in colorectal surgery. (2) Materials and Methods: We performed a retrospective study on the colorectal cancer cases operated in the Fourth Department of General Surgery, Emergency Hospital Bucharest Romania, over the period March 2020–February 2021 (pandemic group) vs. March 2019–February 2020 (non-pandemic group). (3) Results: The number of patients in the pandemic group decreased by 70% (36 vs. 118 patients), with lower accessibility from rural areas (11.1% vs. 37.2%, p = 0.035). Most cases in the pandemic group were emergencies (69% vs. 37.3%, p = 0.009), admitted for bowel obstruction (63.8% vs. 27.9%, p = 0.008). There was no in-hospital COVID-19 infection in patients operated for colorectal cancer. The 30-day mortality was significantly higher in the pandemic group (25% vs. 6.7%, p = 0.017), mostly due to septic shock (36.1% vs. 5%, p = 0.0001). (4) Conclusions: Colorectal cancer surgery may be performed safely during the COVID-19 pandemic, with strict adherence to the SARS-CoV-2 prevention protocols. However, the significant increase in colorectal cancers in the emergency was associated with worse outcomes and higher mortality during the COVID-19 pandemic.

[PMID: 35456285 PMCID: PMC9028106 DOI: 10.3390/jcm11082192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 04/05/2022] [Accepted: 04/07/2022] [Indexed: 11/16/2022] Open
Abstract
Standards of care offer doctors and patients the confidence that an established quality, evidence-based, care is provided, and represent a tool for optimal responding to the population’s needs. It is expected that they will increasingly express a multimodal relationship with gynecologic laparoscopy. Laparoscopy is, now, a standard procedure in operative gynecology, standards are embedded in many laparoscopic procedures, standardization of the skills/competency assessment has been progressively developed, and the proof of competency in laparoscopy may become a standard of care. A continuous development of surgical education includes standard equipment (that may bring value for future advance), standardized training, testing (and performance) assessment, educational process and outcome monitoring/evaluation, patients’ care, and protection, etc. Standards of care and training have a reciprocally sustaining relationship, as training is an essential component of standards of care while care is provided at higher standards after a structured training and as credentialing/certification reunites the two. It is envisaged that through development and implementation, the European wide standards of care in laparoscopic surgery (in close harmonization with personalized medicine) would lead to effective delivery of better clinical services and provide excellent training and education.

Acute surgical abdomen during the COVID-19 pandemic: Clinical and therapeutic challenges. Exp Ther Med 2021; 21:519. [PMID: 33815592 DOI: 10.3892/etm.2021.9950] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 02/17/2021] [Indexed: 02/07/2023] Open
Abstract
The present study investigated the effects of the COVID-19 pandemic on the clinical presentation and therapeutic management of acute surgical abdomen. A retrospective study of emergency hospitalizations with a diagnosis of acute surgical abdomen between April and July 2020 vs. a similar period in 2019 was performed. The observation sheets and the operating protocols were analyzed. Between April and July 2020, 50 cases of acute surgical abdomen were hospitalized and treated, compared to 43 cases in the same period last year. The main types of pathology in both groups included: Occlusions (60%, respectively 44.2% in 2019) and peritonitis (32%, respectively 41.8% in 2019). There was an increased rate of patients with colorectal cancers neglected therapeutically or uninvestigated, who presented during the pandemic period with emergencies for complications such as occlusion or tumor perforation (32 vs. 6.97%, P=0.0039). One case, with gastric perforation, was COVID-positive, with no pulmonary symptoms at admission. The number of postoperative infectious complications was lower during the pandemic (2 vs. 13.95%, P=0.0461). As the COVID-19 pandemic appears to be still far from ending, we should learn to adapt our surgical protocols to the new evidence. Oncological patients are a vulnerable group, who were neglected in the first months of the pandemic. SARS-Cov-2 infection may be a cause of abdominal pain and should be taken into account in different diagnoses of acute abdomen in surgical wards. Correct wearing of adequate personal protective equipment (PPE) and respecting strict rules of asepsis and antisepsis are required for preventing in-hospital transmission of infection.

[PMID: 33821216 PMCID: PMC8013799 DOI: 10.1002/lio2.526] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Accepted: 01/04/2021] [Indexed: 01/07/2023] Open
Abstract
Objective To evaluate a negative pressure microenvironment designed to contain laser plume during flexible transnasal laryngoscopy. Methods The Negative Pressure Face Shield (NPFS) was previously reported as well tolerated with initial use on 30 patients. Diagnostic transnasal laryngoscopy was performed on an additional 108 consecutive patients who were evaluated by questionnaires and sequential pulse oximetry. Further study addressed operative transnasal potassium‐titanyl‐phosphate (KTP) laser laryngoscopy with biopsy done on four patients employing the NPFS. Results The previously described NPFS version 3 (v.3), a transparent acrylic barrier with two anterior instrumentation ports, was modified by repositioning the side suction port closer to the level of the nose and deepening the lateral sides, squaring off the lower projection. A post‐procedure questionnaire employing a 5‐point Likert scale ranging from no symptoms (rating of 1) to intolerable (rating of 5) identified excellent patient tolerance of the new design (v.4), among 22 patients evaluated and similar in the comparison to the 116 patients using version 3. Among the 138 patients analyzed, only one patient rated the experience as greater than “mild claustrophobia.” 100% of patients answered either “none” or “mild” to the pain and shortness of breath questions. The NPFS (v.4) was then successfully used in four patients for laser laryngoscopy with biopsy of laryngeal papilloma (3/4) and hemorrhagic polyp (1/4). Post‐procedure questionnaire identified no shortness of breath (4/4), no claustrophobia (4/4), no pain (4/4) and no significant changes in pulse oximetry during use. Conclusion Extensive experience in performing diagnostic laryngoscopy with the NPFS directed design changes leading to successful use for transnasal flexible laser laryngoscopy with biopsy in a negative pressure microenvironment. Level of Evidence Level 2b (Cohort Study).
