Metabolic and Bariatric Surgery Utilization Trends in the United States: Evidence from 2012-2021 National Electronic Medical Records Data

Objectives: Bariatric surgery has evolved over the past two decades yet assessing trends of bariatric surgery utilization in the growing eligible population is lacking.This study aimed to update the trends in bariatric surgery utilization, changes in types of procedures performed, and the characteristics of patients who underwent bariatric surgery in the US, using real-world data. Method(s): This cross-sectional study was conducted using the TriNetX, a federated electronic medical records network from 2012 to 2021, for adult patients 18 years old or older who had bariatric surgery. Descriptive statistical analysis was conducted to assess patients' demographics and characteristics. Annual secular trend analyses were conducted for the annual rate of bariatric surgery, and the specific procedural types and proportions of laparoscopic surgeries. Result(s): A steady increase in the number of procedures performed in the US over the first six years of the study, a plateau for the following two years, and then a decline in 2020 and 2021 (during the coronavirus-19 pandemic). The annual rate of bariatric surgery was lowest in 2012 at 59.2 and highest in 2018 at 79.6 surgeries per 100,000 adults. During the study period, 96.2% to 98.8% of procedures performed annually were conducted laparoscopically as opposed to the open technique. Beginning in 2012, the Roux-en-Y (RYGB) procedure fell to represent only 17.1% of cases in 2018, along with a sharp decline in the adjustable gastric band (AGB) procedure, replaced by a sharp increase in the sleeve gastrectomy (SG) procedure to represent over 74% of cases in 2018. Conclusion(s): Bariatric surgery utilization in the US showed a moderate decline in the number of RYGB procedures, which was offset by a substantial increase in the number of SG procedures and a precipitous drop in the annual number of AGB procedures.Copyright © 2023

Strangulated obturator hernia in a COVID-19 patient: a rare case presentation and the role of computed tomography in diagnosis

Obturator hernia is a rare cause of acute abdomen resulting from a protrusion of intra-abdominal contents through the obturator foramen in the pelvis. Obturator hernia is often seen in older adults, emaciated individuals, and chronically ill women. The preoperative diagnosis of obturator hernia is frequently delayed because its nonspecific signs and symptoms complicate the diagnostic pro-cess, leading to high mortality rates. The most common clinical presentation of obturator hernia is intestinal obstruction with nausea, vomiting, and abdominal pain. Symptoms caused by the compression and irritation of the obturator nerve within the canal are less common. Open or laparoscopic surgery is the only available treatment;it allows abdominal cavity exploration and hernia reduction. The widespread and increasing use of computed tomography has played an important role in diagnosing conditions. Here, we present the case of a 90-year-old woman di-agnosed with strangulated obturator hernia and coronavirus disease 2019 (COVID-19) who under-went emergency surgery at Hanoi Medical University Hospital. We emphasize the role of computed tomography in establishing a prompt preoperative diagnosis and planning an appropriate surgical intervention for this rare condition.

Socioeconomic Factors Associated with Delay of Minimally Invasive Benign Gynecologic Surgery and Impact of the COVID-19 Pandemic

Objective: The effects of demographic and socioeconomic characteristics on delay of minimally invasive gynecologic surgery (MIGS) before and during the COVID-19 pandemic were studied. The primary outcome was interval between first MIGS appointment and date of surgery. Materials and Methods: This retrospective cohort study used electronic medical record data of a historical cohort who had benign MIGS in 2014-2016 (n = 370) and a cohort in 2020 during the COVID pandemic (n = 249). Included procedures were laparoscopic hysterectomy, myomectomy, adnexal surgery, or endometriosis excision. Patient demographics (race, ethnicity, age, marital status, language, insurance, and socioeconomic factors) were evaluated for associations with surgery delay (> 90 days from initial consultation to operating room date). Results: Median time to surgery was 21 days faster during the pandemic. In the historical cohort, 61% patients waited >90 days, and in the pandemic cohort, 47% patients waited >90 days. In the pandemic cohort, race and primary language were new factors associated with surgery delays. During the pandemic, a greater proportion of patients having surgery delays were Black or other races, compared to White, and a greater proportion did not speak English. After adjusting for referral indications, in multivariable logistic regression, patients who reported Other race had 3 times the odds of surgery delay, compared to White patients. Black patients had higher odds of surgery delay, although this estimate was less precise. Patients with a non-English primary language had >4 times the odds of surgery delay. Ethnicity, insurance and employment status, median household income, neighborhood segregation, and distance to hospital were not associated with surgery delay. Telemedicine accounted for 71% of visits in the pandemic cohort and was associated with a significant decrease in surgery delays with a median wait time of 87 days for patients seen via telemedicine, compared to 101 days for patients seen in-person. A higher proportion of patients using telemedicine were White and spoke English. Hispanic/Latino ethnicity, non-English primary language, and unemployment were associated with in-person versus telemedicine visits. Visit type was not correlated with insurance status, median household income, neighborhood segregation, and distance from the hospital. A risk score was calculated to summarize the estimated effect of intersectionality of multiple identities;multiple minority characteristics were correlated with surgery delays. Time to benign MIGS decreased from historical baselines during the pandemic, indicating improved access to surgical care. This benefit did not apply equally. Disproportionately, White patients who spoke English had no delays and used telemedicine;racial minority patients who did not speak English had greater odds of surgery delays and in-person appointments. Conclusions: Telemedicine can improve access to both MIGS care and surgical outcomes;additional strategies are needed to ensure that all patients receive care advances equitably.

Pseudomembranous colitis in patients with COVID-19 (review)

AIM: to estimate the features of pseudomembranous colitis in patients with COVID-19, diagnostics, conservative treatment and surgery for complications. PATIENTS AND METHODS: a retrospective analysis of 396 patients with pseudomembranous colitis (PMC) in patients with new coronavirus infection was carried out for the period from March 2020 to November 2021. Among them there were 156 (39.3%) males, females - 240 (60.6%), moderate and severe forms of COVID-19 occurred in 97.48%. The diagnosis of PMC was established due to clinical picture, laboratory, instrumental methods (feces on Cl. difficile, colonoscopy, CT, US, laparoscopy). RESULT(S): the PMC rate in COVID-19 was 1.17%. All patients received antibiotics, 2 or 3 antibiotics - 44.6%, glu-cocorticoids were received by all patients. At 82.8%, PMC developed during the peak of COVID-19. To clarify the PMC, CT was performed in 33.8% of patients, colonoscopy - 33.08%, laparoscopy - in 37.1% (to exclude bowel perforation, peritonitis). Conservative treatment was effective in 88.8%, 76 (19.1%) patients had indications for surgery (perforation, peritonitis, toxic megacolon). Most often, with peritonitis without clear intraoperative confir-mation of perforation, laparoscopic lavage of the abdominal cavity was performed (60 patients - 78.9%, mortality - 15.0%), colon resection (n = 6 (7.9%), mortality - 66.6%), ileo-or colostomy (n = 8 (10.5%), mortality - 37.5%), colectomy (n = 2 (2.6%), mortality - 50.0%). The overall postoperative mortality rate was 22.4%, the incidence of surgical complications was 43.4%. In addition, in the postoperative period, pneumonia was in 76.3%, thrombosis and pulmonary embolism in 22.3% of patients. In general, the overall mortality in our patients with PMC was 11.4%, with conservative treatment - 8.8%. CONCLUSION(S): pseudomembranous colitis is a severe, life-threatening complication of COVID-19. In the overwhelm-ing majority of patients, conservative therapy was effective, but almost 1/5 of patients developed indications for surgery, the latter being accompanied by high mortality and a high morbidity rate. Progress in the treatment of PMC, apparently, is associated with early diagnosis, intensive conservative therapy, and in the case of indications for surgery, their implementation before decompensation of the patient's condition and the development of severe intra-abdominal complications and sepsis.Copyright © 2022, Association of Coloproctologists of Russia.

Management of Acute Appendicitis During the COVID-19 Pandemic: A Single-Centre Retrospective Cohort Study.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, the management of acute appendicitis shifted towards non-operative management in the United Kingdom (UK). The open approach was recommended over the laparoscopic approach due to the risk of aerosol generation and subsequent contamination. The aim of this study was to compare the overall management and surgical outcomes of the patients treated for acute appendicitis before and during the COVID-19 pandemic. MATERIALS AND METHODS: We performed a retrospective cohort study at a single district general hospital in the UK. We compared the management and outcome of the patients diagnosed with acute appendicitis before the pandemic, from March to August 2019, and during the pandemic, from March to August 2020. We looked at the patient demographics, methods of diagnosis, management, and surgical outcomes for these patients. The primary outcome of the study was the 30-day readmission rate. Secondary outcomes included length of stay and post-operative complications. RESULTS: Over the period of six months, a total of 179 patients were diagnosed with acute appendicitis in 2019 (Pre-COVID-19 pandemic, from March 1, 2019, to August 31, 2019) versus 152 in 2020 (during the COVID-19 pandemic, from March 1, 2020, to August 31, 2020). For the 2019 cohort, the mean age of the patients was 33 (range 6-86 years), 52% (n=93) were female, and the mean BMI was 26 (range 14-58). For the 2020 cohort, the mean age was 37 (range 4-93 years), 48% (n=73) of the patients were female, and the mean BMI was 27 (range 16-53). At the first presentation, in 2019, 97.2% of the patients (174 out of 179) received surgical treatment compared to 70.4% (107 out of 152) in 2020. Three per cent of the patients (n=5) were managed conservatively in 2019 (two out these failed conservative management) as compared to 29.6% (n=45) in 2020 (21 of these failed conservative management). Pre-pandemic, only 32.4% (n= 57, ultrasound (US) scan: 11, computer tomography (CT) scan): 45, both US and CT: 1) of the patients received imaging to confirm the diagnosis as compared to 53.3% during pandemic (n=81, US scan: 12, CT scan: 63, both US and CT: 6). Overall, the CT to US ratio increased. We found that during 2019, 91.5% (n=161/176) of the patients who received surgical treatment went through laparoscopic surgery as compared to only 74.2% (n=95/128) in 2020 (p<0.0001). Postoperative complications occurred in 5.1% (n=9/176) of the surgical patients in 2019 as compared to 12.5% (n=16/128) in 2020 (p<0.033). The mean length of hospital stay in 2019 was 2.9 days (range 1-11) versus 4.5 days in 2020 (range 1-57) (p<0.0001). The 30-day readmission rate was 4.5% (8/179) versus 19.1% (29/152) (p<0.0001). The 90-day mortality rate was zero for both cohorts. CONCLUSION: Our study shows that the management of acute appendicitis changed due to the COVID-19 pandemic. More patients went through imaging, especially CT scans for diagnosis and received non-operative management with antibiotics only. The open surgical approach became more common during the pandemic. This was associated with longer lengths of hospital stay, more readmissions, and an increase in postoperative complications.

A Clinical Case of Pheochromocytoma Presenting with Decompensated Diabetes Mellitus and Paroxysmal Hypertension

Introduction: Pheochromocytoma is a rare neuroendocrine tumor that originates from the adrenal medulla, less commonly from extraadrenal chromaffin cells (paraganglioma). In about 90% of cases, the tumor produces abnormal amounts of catecholamines. Pheochromocytomas are usually benign, but in rare cases can be malignant. Typical clinical manifestations are the result of the haemodynamic and metabolic effects of catecholamines and usually include paroxysmal hypertension with the classic triad (headache, excessive sweating, palpitations), carbohydrate disorders, etc. Elevated levels of catecholamine metabolites (metanephrine and normetanephrine) tested in plasma or in 24-hour urine confirm the diagnosis. Surgical removal of the tumor is the only radical treatment. Follow-up of patients postoperatively should be lifelong and performed by a multidisciplinary team in a specialized center of expertise. Case report: A 36-year-old female patient referred to the clinic for decompensated diabetes mellitus. Detailed history revealed paroxysmal hypertension and the classic triad of pheochromocytoma. The diagnosis was confirmed by high urinary metanephrine levels and an abdominal CT scan, showing a tumor in the right adrenal gland with features typical of pheochromocytoma. Surgical removal of the pheochromocytoma and normalization of catecholamine levels led to normalization of blood pressure and reversal of diabetes mellitus. Conclusion(s): Pheochromocytoma is a difficult diagnosis in endocrinology practice as it can mimic many other diseases. Early detection and surgical removal of the tumor are crucial to avoid complications caused by elevated serum catecholamine levels.Copyright © 2022 Medical Information Center. All rights reserved.

Appendicular flap transposition in case of the left ureters defects

Introduction & Objectives: The frequency of involvement in the oncological process of the ureters in case of pelvis tumors ranges from 15 to 20%. The use of the appendix as a plastic material for the reconstruction of extended ureteral defects (EUD), including left-sided ones, remains debatable. The main goal of this study is evaluating the clinical and functional results after EUD repair using patchy transposition of the appendix. Material(s) and Method(s): Since August 2019 to June 2021, 8 laparoscopic surgeries were performed to replace the EUD using flap transposition of the appendix. Of these, 6 on the left (75%), 2 on the right (25%). 7 women (87.5%) and 1 man (12.5%) were operated on. Mean age 53+/-10.6 years. Average BMI 25.9 kg/m2. Etiology EUD: 25% radiotherapy (n2), 50% iatrogenic surgery (n4), 12.5% (n1) primary ureteral cancer, 12.5% (n1) non-Hodgkin's lymphoma. In all cases, the first stage was a wide mobilization of the ileocecal angle, the appendix was disconnected with a 45 mm hardware suture, in case of left-sided lesion, the appendix was moved isoperistaltically under the mesentery of the sigmoid colon to the left side after preliminary maximum mobilization of the process on the vascular pedicle in the form of a "triangle". All patients received a 7Fr ureteral stent. CT urography was performed on the 3rd, 7th, 11th days. Dynamic nephroscintigraphy was performed on the 90th day. Result(s): The average length of diastasis is 4.6+/-1.7 cm. The average length of the mobilized appendix was 8+/-1.8 cm. Replacement of the ureter with an appendix and a flap of the bladder according to the Demel method was performed in 1 case (12.5%), according to the Boari method in 1 case (12.5%), in 6 (75%) cases an anastomosis was formed according to the "end-to-end" type. the end". The average duration of the operation was 251+/-40.9 min, blood loss was 121+/-56.7 ml. Median removal of the ureteral stent was 36+/-18.28 days. Duration of hospital stay was 14+/-5.2 days. Median follow-up 10+/-5.3 months. Early complications (<30 days): 2 cases of urinary edema (Clavien-Dindo II), 2 cases of ipsilateral hydronephrosis (Clavien-Dindo I-II). Late complications (>30 days): 1 case of partial failure of ureterocystoanastomosis against the background of Sars-Cov-2 infection (Clavien-Dindo IIIa), 1 case of non-functioning left kidney (Clavien-Dindo IVa). Dynamic nephroscintigraphy was performed in 68.4% of patients, the average isotope accumulation time was 4.23+/-0.25 minutes, the duration of the half-life was 14.26+/-0.52 minutes. Conclusion(s): Flap transposition with the appendix is a technically difficult but possible option for extended ureteral strictures. However, various pathological processes that have developed against the background of previous treatment potentially increase the risk of developing repeated strictures or anastomotic leaks. Therefore, given the small sample of patients, further research on this issue is required.Copyright © 2023.

Tracheal tube cuff pressure during anesthesia for robotic-assisted laparoscopic prostatectomy and the efficacy of an automatic cuff pressure controller (SmartCuff): observational studies of 1-sample paired data.

PURPOSE: The cuff pressure of a tracheal tube may increase during robot-assisted laparoscopic surgery for prostatectomy (RALP), which requires pneumoperitoneum in a steep head-down position, but there have been no studies which confirmed this. METHODS: In study 1, we studied how frequently the cuff pressure significantly increased during anesthesia for the RALP. In study 2, we studied if the SmartCuff (Smiths Medical Japan, Tokyo) automatic cuff pressure controller would minimize the changes in the intracuff pressure. With approval of the study by the research ethics committee (approved number: 20115), we measured the cuff pressures in anesthetized patients undergoing RALP and in those undergoing gynecological laparotomy (as a reference cohort), with and without the use of the SmartCuff. RESULTS: In 21 patients undergoing RALP, a clinically meaningful increase (5 cmH2O or greater) was observed in all the 21 patients (P = 0.00; 95% CI for difference: 86-100%), whereas in 23 patients undergoing gynecological laparotomy, a clinically meaningful decrease (5 cmH2O or greater) was observed in 21 of 23 patients (91%, P < 0.0001; 95% CI for difference: 72-99%). With the use of the SmartCuff, there was no significant increase in the incidence of a clinically meaningful change in the intracuff pressure in either cohort. CONCLUSION: The cuff pressure of a tracheal tube would frequently increase markedly in patients undergoing RALP, whereas it would frequently decrease markedly in patients undergoing gynecological laparotomy. The SmartCuff may inhibit the changes in the cuff pressure during anesthesia.

Virtual fundamentals of laparoscopic surgery (FLS) boot-camp using telesimulation: an educational solution during the COVID-19 pandemic.

BACKGROUND: The Fundamentals of Laparoscopic Surgery (FLS) is an internationally recognized educational and certification program designed to teach the knowledge and skills required for basic laparoscopic surgery. Previously, our institution has organized an FLS boot-camp to teach PGY1 residents the FLS manual skills. During the COVID-19 pandemic, in-person sessions were not possible. The purpose of this study was to utilize telesimulation as an education solution for teaching FLS technical skills to PGY1 residents during the COVID-19 pandemic. METHODS: A virtual FLS program was established. A complete, easily portable FLS kit was distributed to participants and instructors to set up an FLS box and connect remotely using telesimulation. The program was delivered by three senior residents using the Zoom™ platform. Participants were split into groups of 3-4 individuals, each receiving three 1-h sessions. Sessions were structured with initial demonstration of tasks followed by individual coaching of participants in 'break-out' rooms. The official FLS exam was administered in-person on the 4th week. Pre- and post-course surveys were administered to participants gauging self-reported proficiency with FLS tasks and overall course feedback. Anonymized FLS exam results were collected. RESULTS: A total of 14 residents participated, and 11 responded to the survey. Participants reported that their overall FLS skills proficiency significantly improved on a 5-point likert scale from 1.5 ± 0.5 pre-course to 4.0 ± 0.5 post-course (mean ± SD). Participants unanimously stated that having the FLS box at home was valuable and enabled them to practice more. On the FLS exam, 13 of 14 participants passed the manual skills component. CONCLUSIONS: We developed a telesimulation hands-on FLS course as an alternative to in-person training. The course was practical and effective and was preferred to traditional methods by participants. With ever-expanding technological solutions, virtual telesimulation education is an attractive and underutilized tool, not only in the setting of COVID-19, but also more broadly across current educational programs.

Surgical education in the post-COVID era: an EAES DELPHI-study.

BACKGROUNDS: To date, it is unclear what the educational response to the restrictions on minimally invasive surgery imposed by the COVID-19 pandemic have been, and how MIS-surgeons see the post-pandemic future of surgical education. Using a modified Delphi-methodology, this study aims to assess the effects of COVID on MIS-training and to develop a consensus on the educational response to the pandemic. METHODS: A three-part Delphi study was performed among the membership of the European Association of Endoscopic Surgery (EAES). The first survey aimed to survey participants on the educational response in four educational components: training in the operating room (OR), wet lab and dry lab training, assessment and accreditation, and use of digital resources. The second and third survey aimed to formulate and achieve consensus on statements on, and resources in, response to the pandemic and in post-pandemic MIS surgery. RESULTS: Over 247 EAES members participated in the three rounds of this Delphi survey. MIS-training decreased by 35.6-55.6%, alternatives were introduced in 14.7-32.2% of respondents, and these alternatives compensated for 32.2-43.2% of missed training. OR-training and assessments were most often affected due to the cancellation of elective cases (80.7%, and 73.8% affected, respectively). Consensus was achieved on 13 statements. Although digital resources were deemed valuable alternatives for OR-training and skills assessments, face-to-face resources were preferred. Videos and hands-on training-wet labs, dry labs, and virtual reality (VR) simulation-were the best appreciated resources. CONCLUSIONS: COVID-19 has severely affected surgical training opportunities for minimally invasive surgery. Face-to-face training remains the preferred training method, although digital and remote training resources are believed to be valuable additions to the training palette. Organizations such as the EAES are encouraged to support surgical educators in implementing these resources. Insights from this Delphi can guide (inter)national governing training bodies and hospitals in shaping surgical resident curricula in post pandemic times.

Impact of the COVID-19 pandemic on surgical practice in Iraq

Background: The COVID-19 pandemic affects all aspects of life all over the world;general surgeons are highly affected along with other healthcare personnel. A gloomy course of the disease makes it hazardous till now;its impact and ways of protection should be of concern for us so that we can keep on our works. Method(s): A survey was carried out at our hospital among general surgeons and surgeons of other specialties of the course with junior doctors and residents. A questionnaire was answered by them concerning their work with the impact of the virus, collecting data from the statistical unit electronically. Iraq has started lockdown for a period of 24 months from March 2020 to March 2022. Result(s): This study is a cross-sectional study using Google Forms and spread over surgical teams of different specialties at the Imemein Kadhumein Medical City Center. From about 248 responses, 118 responses were taken from the survey. Out of the 50 surgeons, 40 (80%) were infected and out of the 68 residents 62 (91.1%) were infected in our hospital (open and laparoscopic). About 20% of the doctors completely stopped attending outpatient clinics, until vaccination started on March 2021, an overall decrease of 60%. A drop of >75% of income was noticed by 45% of them;and 25% of them feel <75% of the income was received. But others have no change or increase in income as patients shift toward private hospitals because the government ones become loaded with COVID patients. Information about the illness and its sequelae was found through the net to be about 81% and through television to be 16%, whereas others were through national and institutional announcements. Conclusion(s): Standardized measures in detection, treatment, and/or vaccination should be taken into consideration based on the solid scientific facts to have a road map for surgeries during this or subsequent pandemics, getting the best outcome for doctors and patients.Copyright © 2022 Nile, Hamdawi, Khiro, licensee HBKU Press

Emergency surgical strategies for patients with acute abdomen during the COVID-19 outbreak.

Objective: To investigate the emergency surgical strategies for patients with acute abdomen during the Corona Virus Disease 2019 (COVID-19) outbreak. Method(s): The retrospective and descriptive study was conducted. The clinical data of 20 patients with acute abdomen who were admitted to the Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology between January 18, 2020 and February 10, 2020 were collected. There were 13 males and 7 females, aged from 25 to 82 years, with an average age of 57 years. All the patients with emergency surgeries received pulmonary computed tomography (CT) examination before surgery, and completed nucleic acid detection in throat swab if necessary. Patients excluded from COVID-19 underwent regular anesthesia, suspected and confirmed cases were selected a proper anesthesia based on their medical condition and surgical procedure. Patients excluded from COVID-19 underwent emergency surgeries following the regular procedure, suspected and confirmed cases underwent emergency surgeries following the three-grade protection. Observation indicators: (1) surgical situations;(2) postoperative situations. Measurement data with normal distribution were represented as average (range). Count data were described as absolute numbers. Result(s): (1) Surgical situations: of the 20 patients with acute abdomen, 16 patients were excluded from COVID-19, and 4 were not excluded. All the 20 patients underwent emergency abdominal surgeries successfully, of whom 2 received surgeries under epidural anesthesia (including 1 with open appendectomy, 1 with open repair of duodenal bulbar perforation), 18 received surgeries under general anesthesia (including 9 with laparoscopic repair of duodenal bulbar perforation, 3 with open partial enterectomy, 3 with laparoscopic appendectomy, 1 with laparoscopic left hemicolectomy, 1 with laparoscopic right hemicolectomy, 1 with cholecystostomy). The operation time of patients was 32-194 minutes, with an average time of 85 minutes. The volume of intraoperative blood loss was 50-400 mL, with an average volume of 68 mL. (2) Postoperative situations: 16 patients excluded from COVID-19 preopratively were treated in the private general ward postoperatively. One of the 16 patients had fever at the postoperative 5th day and was highly suspected of COVID-19 after an emergency follow-up of pulmonary CT showing multiple ground-glass changes in the lungs. The patient was promptly transferred to the isolation ward for treatment, and results of nucleic acid detection in throat swab showed double positive. Medical history described by the patient showed that the patient and family members were residents of Wuhan who were not isolated at home during the epidemic. There was no way to confirm whether they had a history of exposure to patients with COVID-19. Medical staffs involved in this case did not show COVID-19 related symptoms during 14 days of medical observation. The other 15 patients recovered well postoperatively. The 4 patients who were not excluded from COVID-19 preoperatively based on medical history and results of pulmonary CT examination were directly transferred to the isolation ward for treatment postoperatively. They were excluded from COVID-19 for two consecutive negative results of nucleic acid detection in the throat swab and recovered well. Two of the 20 patients with acute abdomen had postoperative complications. One had surgical incision infection and recovered after secondary closure following opening incision, sterilizing and dressing, the other one had intestinal leakage and was improved after conservative treatment by abdominal drainage. There was no death in the 20 patients with acute abdomen. Conclusion(s): Patients with acute abdomen need to be screened through emergency forward. Patients excluded from COVID-19 undergo emergency surgeries following the regular procedure, and patients not excluded from COVID-19 undergo emergency surgeries following the three-grade protection. The temperature, blood routine test and other l boratory examinations are performed to monitor patients after operation, and the pulmonary CT and throat nucleic acid tests should be conducted if necessary. Patients excluded from COVID-19 preopratively are treated in the private general ward postoperatively, and they should be promptly transferred to the isolation ward for treatment after being confirmed. Patients who are not excluded from COVID-19 preoperatively based on medical history should be directly transferred to the isolation ward for treatment postoperatively.Copyright © 2020 by the Chinese Medical Association.

There was no way to confirm whether they had a history of exposure to patients with COVID-19. Medical staffs involved in this case did not show COVID-19 related symptoms during 14 days of medical observation. The other 15 patients recovered well postoperatively. The 4 patients who were not excluded from COVID-19 preoperatively based on medical history and results of pulmonary CT examination were directly transferred to the isolation ward for treatment postoperatively. They were excluded from COVID-19 for two consecutive negative results of nucleic acid detection in the throat swab and recovered well. Two of the 20 patients with acute abdomen had postoperative complications. One had surgical incision infection and recovered after secondary closure following opening incision, sterilizing and dressing, the other one had intestinal leakage and was improved after conservative treatment by abdominal drainage. There was no death in the 20 patients with acute abdomen. Conclusion(s): Patients with acute abdomen need to be screened through emergency forward. Patients excluded from COVID-19 undergo emergency surgeries following the regular procedure, and patients not excluded from COVID-19 undergo emergency surgeries following the three-grade protection. The temperature, blood routine test and other l boratory examinations are performed to monitor patients after operation, and the pulmonary CT and throat nucleic acid tests should be conducted if necessary. Patients excluded from COVID-19 preopratively are treated in the private general ward postoperatively, and they should be promptly transferred to the isolation ward for treatment after being confirmed. Patients who are not excluded from COVID-19 preoperatively based on medical history should be directly transferred to the isolation ward for treatment postoperatively.Copyright © 2020 by the Chinese Medical Association.

Concept renovation: a new perspective of minimally invasive surgery. TT -:.

The development and innovation of laparoscopic vision platform has promoted the innovation of surgical concept and technology from laparotomy to minimally invasive surgery. From the initial use of reflector device with candlelight to observe the interior of the human body cavity, to the high-definition and ultra-high-definition laparoscopic vision system, from laparoscopic cholecystectomy, to the popularization and promotion of various laparoscopic surgery for malignant tumor, surgery has undergone great changes due to minimally invasive technology. In the new era, the application of three-dimensional and 4K laparoscope brings a new perspective to minimally invasive surgery, so as to promote the development of surgery in the direction of accurate anatomy and functional protection. In the future, stimulated by concept renovation in post-epidemic era of COVID-19, virtual reality technology and robotic surgery supported by the fifth generation wireless systems, as well as tele-surgery and distance training and teaching based on it, will become a new perspective for the development of minimally invasive surgery.Copyright © 2020 by the Chinese Medical Association.

Use of virtual platform for delivery of simulation-based laparoscopic training curriculum in LMICs.

BACKGROUND: Laparoscopic surgery is rapidly expanding in low-and middle-income countries (LMICs), yet many surgeons in LMICs have limited formal training in laparoscopy. In 2017, the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) implemented Global Laparoscopic Advancement Program (GLAP), an in-person simulation-based laparoscopic training curriculum for surgeons in LMICs. In light of COVID-19, SAGES adapted GLAP to a virtual format with telesimulation. This study explores the feasibility and efficacy of virtual laparoscopic simulation training in resource-limited settings. METHODS: Participants from San Jose, Costa Rica, Leon, México, and Guadalajara, México enrolled in the virtual GLAP curriculum, meeting biweekly for 2-h didactic classes and 2-h hands-on live simulation practice. Surgical residents' laparoscopic skills were evaluated using the five Fundamentals of Laparoscopic Surgery (FLS) tasks during the initial and final weeks of the program. Participants also completed pre-and post-program surveys assessing their perception of simulation-based training. RESULTS: The study cohort consisted of 16 surgical attendings and 20 general surgery residents. A minimum 70% response rate was recorded across all surveys in the study. By the end of GLAP, residents completed all five tasks of the FLS exam within less time relative to their performance at the beginning of the training program (p < 0.05). Respondents (100%) reported that the program was a good use of their time and that education via telesimulation was easily reproduced. Participants indicated that the practice sessions, guidance, and feedback offered by mentors were their favorite elements of the training. CONCLUSION: A virtual simulation-based curriculum can be an effective strategy for laparoscopic skills training. Participants demonstrated an improvement in laparoscopic skills, and they appreciated the mentorship and opportunity to practice laparoscopic skills. Future programs can expand on using a virtual platform as a low-cost, effective strategy for providing laparoscopic skills training to surgeons in LMICs.
