RESUMO

OBJECTIVE: To assess the degree of psychological impact among surgical providers during the COVID-19 pandemic. SUMMARY OF BACKGROUND DATA: The COVID-19 pandemic has extensively impacted global healthcare systems. We hypothesized that the degree of psychological impact would be higher for surgical providers deployed for COVID-19 work, certain surgical specialties, and for those who knew of someone diagnosed with, or who died, of COVID-19. METHODS: We conducted a global web-based survey to investigate the psychological impact of COVID-19. The primary outcomes were the depression anxiety stress scale-21 and Impact of Event Scale-Revised scores. RESULTS: A total of 4283 participants from 101 countries responded. 32.8%, 30.8%, 25.9%, and 24.0% screened positive for depression, anxiety, stress, and PTSD respectively. Respondents who knew someone who died of COVID-19 were more likely to screen positive for depression, anxiety, stress, and PTSD (OR 1.3, 1.6, 1.4, 1.7 respectively, all P < 0.05). Respondents who knew of someone diagnosed with COVID-19 were more likely to screen positive for depression, stress, and PTSD (OR 1.2, 1.2, and 1.3 respectively, all P < 0.05). Surgical specialties that operated in the head and neck region had higher psychological distress among its surgeons. Deployment for COVID- 19-related work was not associated with increased psychological distress. CONCLUSIONS: The COVID-19 pandemic may have a mental health legacy outlasting its course. The long-term impact of this ongoing traumatic event underscores the importance of longitudinal mental health care for healthcare personnel, with particular attention to those who know of someone diagnosed with, or who died of COVID-19.

RESUMO

On the sidelines of the 75th Session of the Regional Committee of the World Health Organization for the Americas, the Republic of Ecuador hosted an event to expand on National Surgical, Obstetric, and Anaesthesia Plans (NSOAPs). NSOAPs are policy frameworks that offer governments a pathway to incorporate surgical planning into their overall health strategies. In Latin America, Ecuador became the first country to lead the development of an NSOAP and is fostering regional efforts for other Latin American countries to have sustainable surgical strengthening plans. Brazil is a prominent candidate for enrolling in an NSOAP process to enhance its public health system's functionality. An NSOAP in Brazil can help mitigate social disparities, promote greater efficiency in allocating existing resources, and optimise public health system financing. This process can also encourage the creation of resources and distinct NSOAP vocabulary in Portuguese to facilitate the development of NSOAPs in other Portuguese-speaking and low- and middle-income countries. In this viewpoint, we explore why an NSOAP can benefit Brazil's surgical system, national features that enable surgical policymaking, and how multiple stakeholder engagement can contribute to the country's planning, validation, and implementation of an NSOAP.

RESUMO

AIM: Endoscopic treatment for esophageal variceal has been used as the main intervention in patients with portal hypertension secondary to schistosomiasis, but with significant rates of recurrence of esophageal variceal and rebleeding. The long-term results of exclusive endoscopic treatment are poorly studied as the relationship of the splenic dimensions in this context. The aim of this study was to identify, through ultrasonography, whether the splenic index and the longitudinal (craniocaudal) dimension of the spleen are the predictors of rebleeding and variceal recurrence in late follow-up of patients with nonoperated schistosomiasis, after endoscopic eradication of esophageal variceal. METHODS: This is a retrospective and observational study analyzing the medical records of patients diagnosed with hepatosplenic schistosomiasis. The receiver operating characteristic curve was used to determine the best cutoff point for the mean splenic index as a predictor of recurrence and bleeding. RESULTS: A follow-up of 54 patients were analyzed during the period from 2002 to 2018. The mean follow-up time was 8 years. The splenic index with value >144 was proved to be a sensitive test for rebleeding. In the analysis of the longitudinal dimension, the spleen length of >20 cm showed a statistically significant test for recurrence of variceal and a length >19 cm presented as a very sensitive and statistically significant test for rebleeding. CONCLUSION: Splenic index and craniocaudal dimension analysis, obtained by ultrasonography, can predict recurrence of varicose veins and rebleeding after exclusive endoscopic treatment.


OBJETIVO: O tratamento endoscópico das varizes esofágicas tem sido utilizado como principal intervenção em pacientes com hipertensão portal secundária à esquistossomose, mas com taxas significativas de recorrência de varizes esofágicas e ressangramento. Os resultados em longo prazo do tratamento endoscópico exclusivo são pouco estudados quanto à relação das dimensões esplênicas neste contexto. Avaliar, por meio da ultrassonografia, o índice esplênico e a dimensão longitudinal (craniocaudal) do baço como preditores de ressangramento e recorrência de varizes no seguimento tardio de pacientes esquistossomóticos não operados, após erradicação endoscópica das varizes esofágicas. MÉTODOS: Estudo observacional retrospectivo por meio da análise de prontuários de pacientes com diagnóstico de esquistossomose hepatoesplênica. A curva ROC foi usada para determinar o melhor ponto de corte para o índice esplênico médio como preditor de recorrência e sangramento. RESULTADOS: Foram analisados 54 pacientes, durante o período de 2002 a 2018. O tempo médio de seguimento foi de 8 anos. O índice esplênico provou ser um teste sensível em valores acima de 144 como preditor de ressangramento. Na análise da dimensão longitudinal, o valor acima de 20 cm apresentou teste estatisticamente significativo para recorrência de varizes e valor acima de 19 cm apresentou-se como teste muito sensível e estatisticamente significativo para ressangramento. CONCLUSÃO: A análise do índice esplênico e da dimensão craniocaudal, obtidos por ultrassonografia, podem predizer recorrência de varizes e ressangramento após erradicação endoscópica exclusiva.

RESUMO

OBJECTIVES: The benefits of implementing point-of-care ultrasound (POCUS) in the emergency department are well established. Ideally, physicians should be taught POCUS during medical school. Several different courses have been designed for that purpose and have yielded good results. However, medical students need specifically designed courses that address the main objectives of knowledge acquisition and retention. Despite that, there is limited evidence to support knowledge retention, especially in the mid-term. The purpose of this study is to evaluate short- and mid-term knowledge retention after a student-aimed ultrasound course. METHODS: Medical students participating in a medical student trauma symposium (SIMPALT) in 2017 were included. Their profiles and baseline ultrasound knowledge were assessed by a precourse questionnaire (PRT). The same questionnaire was used one week (1POT) and three months (3POT) after the course. RESULTS: Most of the participants were 1st- to 4th- year medical students. None had prior ultrasound knowledge. They reported costs as the major barrier (65%) to enrollment in an ultrasound course. A comparison between the PRT and 1POT results showed a statistically significant difference (p<0.02), while no difference was found between 1POT and 3POT (p>0.09). CONCLUSION: Our findings support the use of a tailored ultrasound course for medical students. Knowledge acquisition and mid-term retention may be achieved by this specific population.

RESUMO

In the new era of mobile technologies and social media, patient's privacy is at risk. Surgical patients have high visual appeal and may be vulnerable because a significant proportion of cases consist of emergency and trauma, in which patients are frequently unconscious. This study aims to identify the most vulnerable health providers to share patient's confidential data on social media in the surgical environment and their awareness of the confidentiality rules and laws. We surveyed medical graduates, surgical residents, and attending surgeons from a quaternary university hospital. Demographic data, usage and frequency of mobile apparatus, social media access, patient's data dissemination, and knowledge of laws and rules governing patient's privacy were recorded. One hundred fifty-six individuals (52 graduates, 51 residents, and 53 attending surgeons; mean age 24, 28, and 59 years, respectively) participated in the study. Patient's information was shared on social media by 53 per cent of the graduates, 86 per cent of the residents, and 32 per cent of the attending surgeons (P < 0.05). Confidentiality preservation policies were unknown to 69 per cent of graduates, 80 per cent of residents, and 62 per cent of attending surgeons (P = 0.124). Awareness of protocols to guide health-care professionals about safer use of social media was 0 per cent for graduates, 15 per cent for residents, and 22 per cent for attending surgeons (P = 0.002). Residents were the most vulnerable to share patient's information on social media compared with graduates and attending surgeons. Health institutions should promote continuing education in medical ethics, focussing on residents.

RESUMO

PURPOSE: To assess the initial healing after surgical stapling of the stomach using a linear cutting stapler and creating pneumoperitoneum (12-14 mmHg) for 60 minutes or 120 minutes, and compare it with the healing of a staple line not submitted to increased pressure. METHODS: A total of 30 dogs were divided into three groups of 10 animals each: Group I (control group - surgical stapling), Group II (surgical stapling and increased intra-abdominal pressure for 60 minutes) and Group III (surgical stapling and increased intra-abdominal pressure for 120 minutes). All dogs were maintained under general anesthesia for two hours after surgical stapling. Seven days after surgery, the area around the staple line was macroscopically and microscopically examined. RESULTS: The macroscopic examination of the samples (n = 30) did not show dehiscence, fistula or abscess. Adhesions between the omentum and the staple line were observed in all animals of Groups II and III (n = 20), which were significantly different from Group I (p = 0.008*). The histopathological analysis showed normal healing up to day 7 in the control animals (n = 10). When these results were compared with those of Groups II and III (n = 20), non-parametric tests revealed that there was a significant difference with regard to certain parameters of the early stages of healing, such as fibroblast migration (p = 0.011*), edema (p < 0.001*) and congestion (p = 0.011*). These alterations affected reepithelization (p < 0.001*), and consequently the late stages of healing. CONCLUSIONS: Each group showed different healing stages, and the healing process was delayed in the groups submitted to increased pressure, especially in the group submitted to increased pressure for longer time.

RESUMO

BACKGROUND/AIMS: Endoscopic therapy for esophageal varices may lead to esophageal dysmotility. High-resolution manometry is probably the more adequate tool to measure esophageal motility in these patients. This study aimed to evaluate esophageal motility using high resolution manometry following eradication of esophageal varices by endoscopic sclerotherapy. METHODS: We studied 21 patients (11 women, age 52 [45-59] years). All patients underwent eradication of esophageal varices with endoscopic sclerotherapy and subsequent high resolution manometry. RESULTS: A significant percentage of defective lower esophageal sphincter (basal pressure 14.3 [8.0-20.0] mmHg; 43% hypertonic) and hypocontractility (distal esophageal amplitude 50 [31-64] mmHg; proximal esophageal amplitude 40 [31-61] mmHg; distal contractile integral 617 [403-920] mmHg·sec·cm; 48% ineffective) was noticed. Lower sphincter basal pressure and esophageal amplitude correlated inversely with the number of sessions (P < 0.001). No manometric parameter correlated with symptoms or interval between last endoscopy and manometry. CONCLUSIONS: Esophageal motility after endoscopic sclerotherapy is characterized by: (1) defective lower sphincter and (2) defective and hypotensive peristalsis. Esophageal dysmotility is associated to an increased number of endoscopic sessions, but manometric parameters do not predict symptoms.

RESUMO

Short esophagus is defined as the inability to reduce the gastroesophageal junction below the diaphragm. One of the factors responsible for this inability can be inadequate esophageal mobilization. We evaluated esophageal lengthening achieved by means of dissection in a cadaveric model. Fifty-one cadavers were dissected (27 transthoracically and 24 transhiatally). Abdominal esophageal length was assessed before and after dissection of the esophagus from the hiatus to the carina. In the transthoracic group, a mean of 1.7+/-1.3 cm (range 0.3 to 5.0 cm) was gained with dissection. In the transhiatal group, a mean of 1.8+/-0.8 cm (range 0 to 3.0 cm) was gained with dissection. In a comparison of results of transthoracic and transhiatal approaches, the difference was not statistically significant. We concluded that a significant increase in esophageal length was achieved after dissection; however, the access route (thorax or abdomen) did not influence the results.

RESUMO

BACKGROUND: In Brazil, gastric cancer is the fourth most common malignancy among men and sixth among women. The cause is multivariate and the risks are well known. It has prognosis and treatment defined by the location and staging of the tumor and number of lymph nodes resected and involved. AIM: The Brazilian Consensus on Gastric Cancer promoted by ABCG was designed with the intention to issue guidelines that can guide medical professionals to care for patients with this disease. METHODS: Were summarized and answered 43 questions reflecting consensus or not on diagnosis and treatment that may be used as guidance for its multidisciplinary approach. The method involved three steps. Initially, 56 digestive surgeons and related medical specialties met to formulate the questions that were sent to participants for answers on scientific evidence and personal experience. Summaries were presented, discussed and voted in plenary in two other meetings. They covered 53 questions involving: diagnosis and staging (six questions); surgical treatment (35 questions); chemotherapy and radiotherapy (seven questions) and anatomopathology, immunohistochemistry and perspective (five questions). It was considered consensus agreement on more than 70% of the votes in each item. RESULTS: All the answers were presented and voted upon, and in 42 there was consensus. CONCLUSION: It could be developed consensus on most issues that come with the care of patients with gastric cancer and they can be transformed in guidelines.

RESUMO

PURPOSE: Extended mediastinal lymphadenectomy is gaining popularity in the treatment of esophageal cancer, but lymph node nomenclature and classification is still not standardized. The normal mediastinal lymph node distribution according to the classification of the Japanese Society for Esophageal Diseases has never been studied. METHODS: We dissected 20 fresh adult cadavers to examine the mediastinal lymph nodes. RESULTS: We found an unpredictable and inconstant distribution. CONCLUSION: Previous papers have evaluated the number and distribution of normal mediastinal lymph nodes, clinically, radiologically, and anatomically, but the results are conflicting and inconsistent.
