RESUMEN
BACKGROUND: Antivirals have been given widely for patients with COVID-19 breakthrough in Asian countries, creating a "black market" for unapproved and unprescribed medications. More evidence is needed to clarify the benefits of antivirals in these settings. METHODS: We conducted a random-sampling retrospective cohort study at a general hospital in Vietnam. We recruited patients with mild-to-moderate COVID-19 breakthrough who were given either standard of care (SoC) alone or SoC + antiviral. Primary outcome was residual respiratory symptoms that lasted > 7 days. Secondary outcome was long COVID-19, diagnosed by specialized physicians. We used logistic regression to measure odds ratio (OR), in addition to a sensitivity and subgroup analyses to further explore the results. RESULTS: A total of 142 patients (mean age 36.2 ± 9.8) were followed. We recorded residual symptoms in 27.9% and 20.3% of the SoC and SoC + antiviral group, while the figures for long COVID-19 were 11.8% and 8.1%, respectively. Antiviral use was not significantly associated with lower the risks of residual symptoms (OR = 0.51, 95% CI: 0.22-1.20, p = 0.12) or long COVID-19 (OR = 0.55, 95% CI: 0.16-1.90, p = 0.35). The sensitivity and subgroup analyses did not show any significant differences between the study groups (all p > 0.05). CONCLUSION: Antivirals were not associated with faster resolution of respiratory symptoms or lower risks of long COVID-19. Further studies should focus on different antivirals to confirm their effects on different sub-populations. Meanwhile, antivirals should only be used in very high-risk patients to avoid excessive costs and harms.

Background: Antimicrobial Stewardship Programs (ASP) have been applied widely in high-resource countries to prevent surgical site infections (SSI). Evidence favoring ASP interventions (ASPi) in gastrointestinal surgeries from low and middle-income countries has been limited, especially in antimicrobial prophylaxis. We aimed to investigate this gap at a Vietnamese tertiary hospital. Methods: We conducted a retrospective cohort study on patients undergoing clean-contaminated surgeries in 2015 who received standard of care (SoC) or SoC + ASPi. Primary outcome was 30-day SSI incidence. Secondary outcomes included length of stay (LoS) after surgery (days), cost of antibiotics, and cost of treatment (USD). Results were controlled for multiplicity and reported with treatment effect and 95% confidence interval (95%CI). A predictive model was built and cross-validated to detect patients at high risk of SSI. Results: We included 395 patients for analysis (48.1% being female, mean age 49.4 years). Compared to patients receiving SoC, those with SoC + ASPi had a lower incidence of 30-day SSI (-8.8, 95%CI: -16.0 to -1.6, p = 0.042), shorter LoS after surgery (-1.1 days, 95%CI: -1.8 to -0.4, p = 0.004), and lower cost of antibiotics (-37.3 USD, 95%CI: -59.8 to -14.8, p = 0.012) and treatment (-191.1 USD, 95%CI: -348.4 to -33.8, p = 0.042). We estimated that by detecting patients at high risk of SSI with the predictive model and providing prophylactic measures, we could save 398120.7 USD per 1,000 cases of SSI. Conclusion: We found that ASPi were associated with a reduction in risks of SSI, hospital stays, and cost of antibiotics/treatment in a Vietnamese tertiary hospital.

RESUMEN
OBJECTIVES: This study investigated remdesivir's clinical use to provide direct evidence of effectiveness for a low-middle income Asian setting. DESIGN: A one-to-one propensity score matching retrospective cohort study. SETTING: A tertiary hospital with COVID-19 treatment facilities in Vietnam. PARTICIPANTS: A total of 310 patients in standard of care (SoC) group were matched with 310 patients in SoC+remdesivir (SoC+R) group. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was time to critical progression, defined as all-cause mortality or critical illness. The secondary outcomes were length of oxygen therapy/ventilation and need for invasive mechanical ventilation. Outcome reports were presented as HR, OR or effect difference with 95% CI. RESULTS: Patients receiving remdesivir had a lower risk for mortality or critical illness (HR=0.68, 95% CI 0.47 to 0.96, p=0.030). Remdesivir was not associated with a shorter length of oxygen therapy/ventilation (effect difference -0.17 days, 95% CI -1.29 to 0.96, p=0.774). The need for invasive mechanical ventilation was lower in SoC+R group (OR=0.57, 95% CI 0.38 to 0.86, p=0.007). CONCLUSIONS: This study's results showing remdesivir's benefits in non-critical patients with COVID-19 may be extrapolated to other similar low-middle income countries, allowing more regimens for limited resource areas and reducing poor outcomes and equity gap worldwide.

Background The coronavirus disease 2019 (COVID-19) pandemic caused changes in surgical practice. For acute appendicitis (AA), measures to control the pandemic might hinder patients from seeking medical care timely, resulting in increasing severity, postoperative complications, and mortality. This study aimed to investigate whether the COVID-19 pandemic had a negative impact on the severity and postoperative outcomes of patients with AA. Methodology We retrospectively reviewed medical records of AA patients treated operatively at Nhan Dan Gia Dinh Hospital hospital from June 1st to September 30th in three consecutive years: pre-pandemic (2019)/Group 1, minor waves (2020)/Group 2, and major wave (2021)/Group 3 (2021). Data were collected focusing on the duration of symptoms, severity of AA, time from admission to operation, postoperative complications, and mortality. Results There were 1,055 patients, including 452 patients in Group 1, 409 in Group 2, and 194 in Group 3. The overall number of patients decreased mainly in non-complicated AA. The percentages of hospital admission after 24 hours gradually increased (20.8%, 27.9%, and 43.8%, p < 0.05). The percentages of complicated AA in Group 2 and Group 3 were statistically higher than in Group 1 (39% and 55% vs. 31%, p < 0.05). Waiting time for operation increased to five hours during the major wave. Laparoscopic appendectomy was performed in 98-99% of AA patients during the pandemic, with an early postoperative complication rate of 5-9% and a mortality rate of 0.2-1%. Conclusions Although the percentages of hospital admission after 24 hours and complicated AA increased, laparoscopic appendectomy was still feasible and effective and should be maintained as the standard management for AA during the COVID-19 pandemic.
RESUMEN
Purpose: The aim of this study was to validate the low anterior resection syndrome (LARS) score questionnaire in the Vietnamese language among Vietnamese patients who underwent sphincter-preserving surgery for rectal cancer. Methods: The LARS score questionnaire was translated from English into Vietnamese and then back-translated as recommended internationally. From January 2018 to December 2020, 93 patients who underwent sphincter-preserving surgery completed the Vietnamese version of the LARS score questionnaire together with an anchored question assessing the influence of bowel function on quality of life (QoL). To validate test-retest reliability, patients were requested to answer the LARS score questionnaire twice. Results: Ninety-three patients completed the LARS score questionnaire, of whom 89 responded twice. The patients who responded twice were included in the analysis of test-retest reliability. Fifty-eight patients had a "major" LARS score. The LARS score was able to discriminate between patients who were obese and those who were not (P<0.001) and between the low anterior resection and anterior resection procedures (P<0.001). Age and sex were not associated with higher LARS scores (P=0.975). There was a perfect fit between the QoL category question and the LARS score in 56.2% of cases, and a moderate fit was found in 42.7% of cases, showing reasonable convergent validity. The test-retest reliability of 89 patients showed a high intraclass correlation coefficient. Conclusion: The Vietnamese version of the LARS score questionnaire is a valid tool for measuring LARS.
RESUMEN
PURPOSE: Laparoscopic surgery is considered a promising approach for Hartmann reversal but is also a complicated major surgical procedure. We conducted a retrospective analysis at a city hospital in Vietnam to evaluate the treatment technique and outcomes of laparoscopic Hartmann reversal (LHR). METHODS: A colorectal surgery database in 5 years between 2015 and 2019 (1,175 cases in total) was retrieved to collect 35 consecutive patients undergoing LHR. RESULTS: The patients had a median age of 61 years old. The median operative time was 185 minutes. All the procedures were first attempted laparoscopically with a conversion rate of 20.0% (7 of 35 cases). There was no intraoperative complication. Postoperative mortality and morbidity were 0 and 11.4% (2 medical, 1 deep surgical site infection, and 1 anastomotic leak required reoperation) respectively. The median time to first bowel activity was 2.8 days and median length of hospital stay was 8 days. CONCLUSION: When performed by skilled surgeons, LHR is a feasible and safe operation with acceptable morbidity rate.
RESUMEN
BACKGROUND: The benefit of one-stage surgery in emergency surgery for obstructing colorectal cancer (oCRC) by colorectal surgeons has increased during the last century but little is known about the outcomes of this technique conducted by general surgeons in developing countries. This retrospective study was to evaluate the outcomes of emergency surgery for oCRC in a general surgery unit. METHODS: A retrospective review of data from 1175 patients who underwent colorectal surgery between January 2013 and January 2018 was performed. Among these, a total of 186 patients with oCRC who underwent surgery within 24 h of hospital admission were analyzed. For patients with resectable right-sided oCRC, one-stage surgery was performed. For left-sided oCRC, primary anastomosis was mainly attempted; otherwise, a stoma was formed. The rates of primary resection, PRa, stoma, mortality, and morbidity were evaluated. RESULTS: Among 186 patients, oCRC involving the right colon, left colon, and rectum were found in 33.3%, 59.1% and 7.5% respectively. Primary resection and anastomosis were performed in 100%, 44.7%, and 0% of patients with oCRC in the right colon, left colon, and rectum respectively. The complication incidence based on Clavien-Dindo grade III or higher was 16.1% and the mortality rate was 7.5%. The median length of hospital stay was 8.5 days, ranging from 2 to 70 days. CONCLUSION: General surgeons with colorectal surgery experience can still manage oCRC effectively. Primary resection and anastomosis for left-sided oCRC is safe in selective patients. The emergency surgery for oCRC could be benefit with the participation of colorectal surgeons.
