Preserving Left Aberrant Hepatic Artery during Gastrectomy for Cancer – Literature Review and Case Report

Introduction: Identifying left aberrant hepatic artery during gastrectomy for cancer is occasional. In case of replaced left hepatic artery, its ligation can lead to hepatic injury or ischemia, while preserving it can cause difficulties during lymphadenectomy. In literature there is no consensus regarding preserving replaced left hepatic artery during gastrectomy for cancer. A recent study, analysing adverse effects of ligating an aberrant left hepatic artery, shows in pacients with over 5 times elevated transaminase levels, increase in hospital length and postoperative complications. On the other hand, there are studies that consider ligation of aberrant left hepatic artery safe, the only inconvenient being postoperative transient elevation of transminase levels, when ligated artery diameter is over 1.5 mm. Matherial and methoods: We report the case of a 65 years old male, known with myocardial infarction, admitted for epigastric pain, nausea, vomiting, dysphagia for solids and important weight loss. Upper gastrointesinal endoscopy with biopsy and computed tomography showed eso-gastric tumoral mass, signet ring cell carcinoma, no metastases. Intraopertive, we found replaced left heaptic artery arising from left gastric artery, close to the celiac trunk, its diameter being approximately 1 cm. Total radical D2 gastrectomy with mechanical eso-jejunal Roux-en-Y anastomosis was performed. Postoperative evolution was favourable surgically, but the patient had SarsCov2 infection during hospitalisation The final pathology report showed 18 lymph nodes examined, 5 being with adenocarcinoma metastases. Conclusions: Preserving replaced left hepatic artery during gastectomy for cancer is preferable, lyphadecnectomy not being affected. Potential postoperative complications resulted from ligation of replaced left hepatic artery could have chanced the prognosis. © 2023 Bucharest College of Physicians. All Rights Reserved.

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

The financial impact of the COVID-19 pandemic on sleeve gastrectomy at a major academic institution.

INTRODUCTION: The COVID-19- pandemic significantly impacted metabolic and bariatric surgery (MBS) practices due to large-scale surgery cancellations along with staff and supply shortages. We analyzed sleeve gastrectomy (SG) hospital-level financial metrics before and after the COVID-19 pandemic. METHODS: Hospital cost-accounting software (MicroStrategy, Tysons, VA) was reviewed for revenues, costs, and profits per SG at an academic hospital (2017-2022). Actual figures were obtained, not insurance charge estimates or hospital projections. Fixed costs were obtained through surgery-specific allocation of inpatient hospital and operating-room costs. Direct variable costs were analyzed with sub-components including: (1) labor and benefits, (2) implants, (3) drug costs, and 4) medical/surgical supplies. The pre-COVID-19 period (10/2017-2/2020) and post-COVID-19 period (5/2020-9/2022) financial metrics were compared with student's t-test. Data from 3/2020 to 4/2020 were excluded due to COVID-19-related changes. RESULTS: A total of 739 SG patients were included. Average length of stay (LOS), Center for Medicaid and Medicare Case Mix Index (CMI), and percentage of patients with commercial insurance were similar pre vs. post-COVID-19 (p > 0.05). There were more SG performed per quarter pre-COVID-19 than post-COVID-19 (36 vs. 22; p = 0.0056). Pre-COVID-19 and post-COVID-19 financial metrics per SG differed significantly for, respectively, revenues ($19,134 vs. $20,983) total variable cost ($9457 vs. $11,235), total fixed cost ($2036 vs. $4018), total profit ($7571 vs. $5442), and labor and benefits cost ($2535 vs. $3734; p < 0.05). CONCLUSIONS: The post-COVID-19 period was characterized by significantly increased SG fixed cost (i.e., building maintenance, equipment, overhead) and labor costs (increased contract labor), resulting in precipitous profit decline that crosses the break-even in calendar year quarter (CQ) 3, 2022. Potential solutions include minimizing contract labor cost and decreasing LOS.

Primary Care Physicians' Knowledge, Attitude and Practice towards Bariatric Operations in the Kingdom of Bahrain

Background: Obesity is an epidemic treatable disease. In Bahrain, the prevalence of obesity was 36.2%. Bariatric surgery should be considered for patients with BMI >= 40, or >= 30 with obesity-related comorbidities. Family physicians have a key role in identifying and counseling patients who may qualify for bariatric surgery. The most common reason for physicians' refusal of referral for bariatric surgeries is fear of complications followed by concern of ineffective weight loss following the surgery. Doctors are not comfortable providing post bariatric operation care. Aim(s): To study the PCPs' knowledge, attitude and practice towards bariatric surgeries in the kingdom of Bahrain. Method(s): this is a cross-sectional study of a convenient sample of physicians working in the Kingdom of Bahrain health centers, using an electronic and manual questionnaire to test the knowledge, attitude and practice towards bariatric surgery. Result(s): The sample included a total of 222 participants. 56.1% agreed that the BMI >= 40 without weight related comorbidities is an indication for bariatric surgery and 92.3% of them referred patients for bariatric surgery, with BMI (88.6%) as the most influential factor followed by presence of comorbidities (87.8%). On the other hand, lack of resources was the main cause for not referring patient for bariatric surgery (29.4%) followed by concerns with follow up (23.5%). 80.6% are comfortable to initiate conversations with their patients about bariatric surgery, while 36.1% feel comfortable explaining the procedural options to a patient. 83.8% agreed that additional medical education in bariatric surgical care would be useful. Conclusion(s): Primary care physicians showed well knowledge about the referral criteria to bariatric surgeries and that's reflected by the high referral rate (92.3%). But there is a gap in the knowledge mean score across different age groups and experience. Less than half of the physicians are not comfortable dealing with patients. Continuous medical education is essential to address the gap and to establish comprehensive obesity management guidelines for primary care physicians.Copyright © 2023, Bahrain Medical Bulletin.

Influence of perioperative oral nutritional supplementation on short-term efficacy of laparoscopic sleeve gastrectomy for obesity patients: a prospective study

Objective: To investigate the effect of perioperative oral nutritional supplementation on the short-term curative effect of obese patients after laparoscopic sleeve gastrectomy (LSG). Methods: A prospective research method was adopted. The clinical data of 218 obese patients who underwent LSG in Ningxia Medical University General Hospital from January 2018 to December 2021 were selected. The patients who received oral nutritional supplement therapy during the perioperative period were set as the experimental group, and those who received conventional treatment were set as the control group. Observation indicators: (1) Grouping of enrolled patients. (2) Postoperative and follow-up situation. (3) Nutrition-related indicators. (4) Diet compliance. (5) Status of weight loss-related indicators. Follow-up visits were conducted by telephone, We Chat and outpatient visits. The patients were followed up once 30 days after discharge, including albumin (Alb), hemoglobin (Hb), dietary compliance and weight loss-related indicators. The follow-up time will end in February 2022. The measurement data with normal distribution were expressed as x+or-s, and the comparison between groups was performed by independent sample t test. The measurement data is represented by M (range), and the comparison between groups is performed by Mann?Whitney U test. Enumeration data were expressed as absolute numbers or percentages, and the X2 test was used for comparison between groups. Repeated measures data were analyzed by repeated measures analysis of variance. The rank sum test was used to compare the rank data. Results (1) Grouping of the enrolled patients. Screened 218 eligible patients;42 males and 176 females;age (32+or-9) years;body mass index (BMI) (39+or-7) kg/m2. Among the 218 patients, there were 109 cases in the test group and 109 cases in the control group. Gender (male, female), age, BMI, preoperative Alb, and preoperative Hb of patients in the test group were 17 and 92 cases, (33+or-9) years old, (39+or-7) kg/m2, (40.6+or-4.8) g /L, (141.7+or-13.9) g/L;the above indicators in the control group were 25 and 84 cases, (31+or-8) years old, (39+or-8) kg/m2, (40.9+or-4.2) g/L, (142.9+or-9.7) g/L;there was no significant difference in the above (X2=1.89, t=-1.52, 0.51, 0.40, 0.71, P > 0.05). (2) Postoperative and follow-up situation. The first hospitalization time and first hospitalization expenses of the patients in the experimental group were (9.1+or-2.9) d and (3.6+or-0.5) ten thousand yuan respectively;the above indicators of the patients in the control group were (4.9+or-1.0) ten thousand yuan respectively;There were statistically significant differences in the above indicators between the two groups (t=5.58, 12.38, P < 0.05). Among the 218 patients, 119 were followed up, including 62 in the experimental group and 57 in the control group. The 119 patients were followed up for 31.0 (25.0-38.0) days. Among the 218 patients, 14 cases had postoperative complications and led to rehospitalization, including 2 cases in the experimental group, 1 case of nausea and vomiting and 1 case of intestinal obstruction;12 cases in the control group, 10 cases of nausea and vomiting, gastric fistula 2 cases;there was a statistically significant difference between the two groups in hospital readmission (X2=7.63, P < 0.05). The time interval between re-admission and first discharge of 14 patients was (22.0+or-6.7) days. (3) Nutrition-related indicators. The Alb and Hb levels of 62 patients in the experimental group who were followed up before operation, before the first discharge, and 1 month after operation were (40.4+or-5.5) g/L, (35.9+or-3.8) g/L, (45.4+or-2.9) g/L, respectively and (140.8+or-13.9) g/L, (130.5+or-16.9) g/L, (147.8+or-17.2) g/L;the above indicators of 57 patients in the control group were (41.2+or-3.9) g/L, (34.2 +or-3.9) g/L, (42.7+or-5.3) g/L and (143.0+or-9.7) g/L, (122.9+or-12.8) g/L, (139.0+or-11.4) g/L;There was a statistically significant difference between the Alb and Hb groups from preoperative to postoperative 1 mont

The impact of COVID-19 for postoperative outcomes using a nationwide Japanese database of patients undergoing distal gastrectomy for gastric cancer

Background: The coronavirus disease 2019 (COVID-19) pandemic had resulted in either failure to provide required medical resources or delayed treatment for gastric cancer patients. This study aimed to investigate the impact of COVID-19 on the incidence of postoperative complications using a nationwide Japanese database of patients undergoing distal gastrectomy for gastric cancer. Method(s): We collected the data of patients who underwent distal gastrectomy from January 2018 to December 2021 from the National Clinical Database (NCD), a web-based surgical registration system in Japan. The number of surgical cases, the use of intensive care units, and the incidence of morbidity per month were analyzed. We also calculated the standardized mortality ratio (SMR), defined as the ratio of the number of observed patients to the expected number of patients calculated using the risk calculator established in the NCD, for several morbidities, including pneumonia, sepsis, 30-day mortality, and surgical mortality. Result(s): A decrease of 568 gastrectomies was observed from April 2020 to May 2020. Although the absolute number of patients admitted to intensive care units had declined since 2020, the proportion of patients admitted to the ICU did not change before and after the pandemic. Mortality and critical morbidity (such as pneumonia and sepsis) rates were not worse during the pandemic compared to pre-pandemic periods per the SMR. Conclusion(s): Surgical management was conducted adequately through the organized efforts of the entire surgery department in our country even in a pandemic during which medical resources and staff may have been limited.Copyright © 2023 The Authors.

Post-Operative but Not Pre-Operative COVID-19 Predicts Serious Complications and Mortality Following Elective Bariatric Surgery.

PURPOSE: We sought to characterize the prevalence and subsequent impact of pre- and post-operative COVID-19 diagnosis on bariatric surgery outcomes. COVID-19 has transformed surgical delivery, yet little is known regarding its implications for bariatric surgery. MATERIALS AND METHODS: The Metabolic and Bariatric Accreditation and Quality Improvement Program (MBSAQIP) database was evaluated with three cohorts described: those diagnosed with COVID-19 pre-operatively (PRE), post-operatively (POST), and those without a peri-operative COVID-19 (NO) diagnosis. Pre-operative COVID-19 was defined as COVID-19 within 14 days prior to the primary procedure while post-operative COVID-19 infection was defined as COVID-19 within 30 days after the primary procedure. RESULTS: A total of 176,738 patients were identified, of which 174,122 (98.5%) had no perioperative COVID-19, 1364 (0.8%) had pre-operative COVID-19, and 1252 (0.7%) had post-operative COVID-19. Patients who were diagnosed with COVID-19 post-operatively were younger than other groups (43.0 ± 11.6 years NO vs 43.1 ± 11.6 years PRE vs 41.5 ± 10.7 years POST; p < 0.001). Pre-operative COVID-19 was not associated with serious complications or mortality after adjusting for comorbidities. Post-operative COVID-19, however, was among the greatest independent predictors of serious complications (OR 3.5; 95% CI 2.8-4.2; p < 0.0001) and mortality (OR 5.1; 95% CI 1.8-14.1; p = 0.002). CONCLUSIONS: Pre-operative COVID-19 within 14 days of surgery was not significantly associated with either serious complications or mortality. This work provides evidence that a more liberal strategy which employs early surgery after COVID-19 infection is safe as we aim to reduce the current bariatric surgery case backlog.

Lessons from the COVID-19 pandemic: remote coaching in bariatric surgery.

BACKGROUND: The development of fast internet connection has stimulated different types of video-assisted teaching programs. However, a remote mentoring with the proctor not on site has never been reported in bariatric surgery. We described our experiences with remote telementoring for laparoscopic sleeve gastrectomy. METHODS: A qualified general surgeon at the beginning of his bariatric practice performed a series of 8 laparoscopic sleeve gastrectomies (LSG) while tutored by an experienced bariatric surgeon connected from a different city through a specific videoconferencing platform. Data on demographics at baseline, operative time, hospital stay, intraoperative early, and late complications were collected. RESULTS: Mean age and BMI of patients were 36.9 ± 9.6 years old and 41.8 ± 1.7 kg/m2. All procedures were carried out without conversion to open or complications. Mean operative time was 112.4 ± 21.9 min while the hospital stay was 3.5 ± 0.5 days. Operative time significantly decreased after the fourth operation. CONCLUSIONS: Remote coaching appears to be possible and safe for LSG.

[Impact of the COVID pandemic on treatment of bariatric patients in Germany-An analysis of the national StuDoQ/MBE register]. / Auswirkungen der COVID-Pandemie auf die Versorgung bariatrischer Patienten in Deutschland ­ eine Analyse des nationalen StuDoQ/MBE-Registers.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic the standard inpatient care of patients was restricted to increase overall and intensive care capacity reserves for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected persons. OBJECTIVE: This article presents the impact of the COVID-19 pandemic on the surgical and postoperative care of bariatric patients in Germany. MATERIAL AND METHODS: A statistical analysis of the national StuDoQ/MBE register data for the period from 1 May 2018 until 31 May 2022 was performed. RESULTS: Throughout the entire study period there was a continuous increase in documented operations, which continued even during the COVID-19 pandemic. A significant intermittent decline in surgery performed was observed only during the imposition of first lockdown in the months of March to May 2020, with a minimum number of 194 cases performed monthly in April 2020. The pandemic had no measurable effect on the surgically treated patient population, the type of surgical procedure, the perioperative and postoperative outcomes and follow-up care. CONCLUSION: Based on the results of the StuDoQ data and the current literature, it can be deduced that bariatric surgery can be carried out with no increased risk during the COVID-19 pandemic and the quality of postoperative care is not impaired.

Cancer, Covid and Control of Ra - a Toxic Combination?

Case report - Introduction: This case highlights the dilemma of keeping rheumatoid arthritis disease under control in active cancer cases and establishing a consistent multidisciplinary dialogue during a pandemic and staffing crises. During chemotherapy and active cancer treatment, disease-modifying therapies (conventional and biologic) are often stopped. In some cases, the potential benefits versus risks of restarting usual therapies have to be balanced against risks of suppressing disease activity with highdose steroids. Risks of infection (common and atypical) need to be considered. Case report - Case description: A is a 67-year-old female nonsmoker diagnosed with seropositive rheumatoid arthritis (RF, anti - CCP positive) in 2008. Other conditions include type 2 diabetes, atrial fibrillation (on warfarin), hypothyroidism and obstructive sleep apnoea. Due to active disease, despite triple therapy (methotrexate, sulphasalazine and hydroxychloroquine), anti-TNF therapy (etanercept) commenced in 2009 with primary non-response. However, she responded well to B-cell therapy (rituximab) in conjunction with oral methotrexate (25mg weekly) receiving annual infusions from 2010 to 2016. In 2017, an elective sleeve gastrectomy procedure for high BMI was abandoned after peritoneal deposits of concern were noted. Histology and CT imaging were consistent with a primary peritoneal malignancy (Stage 3c low-grade serous adenocarcinoma). Treatment involved debulking surgery (total abdominal hysterectomy, bilateral salpinoophorectomy, omentectomy) and tamoxifen. Treatment for rheumatoid arthritis stalled during this period but as frequent steroids were required for active joint inflammation, in agreement with the oncologists, she had a rituximab cycle in 2018. Unfortunately, in 2019 she had signs of cancer progression (elevated tumour markers, CT imaging) and has subsequently started carboplatin chemotherapy. She has been unable to continue methotrexate or rituximab pending completion of the chemotherapy cycles (ongoing). However, her arthritis is now uncontrolled without increased steroids. Due to recurrent flares, her maintenance dose has been increased from 5mg to 7.5-10mg prednisolone daily until we can establish if it is safe and appropriate to recommence her usual arthritis regime. Even without disease-modifying therapy like methotrexate and rituximab, risk of infection (including atypical ones) is still significant with the combination of chemotherapy and steroids. Risk of progressive joint damage and adverse quality of life with active arthritis also needs to be considered. Staffing crises, exacerbated by COVID pandemic issues, have added to complexity of decision making and coordination of regular multidisciplinary discussions regarding treatment. Case report - Discussion: Cancer is a known association in rheumatoid arthritis patients with a twofold higher risk of lymphoma compared to the general population. Whether condition or treatment affects risk remains unclear as immune dysregulation is relevant in both autoimmunity and cancer. Paraneoplastic, recent onset arthritis, chemotherapy- or immunotherapy-induced arthralgia/arthritis are also well documented. This case had a seropositive rheumatoid arthritis phenotype quite a few years prior to cancer diagnosis. Primary peritoneal cancer is uncommon, often presenting as in this case as an incidental finding. It is usually treated like ovarian cancer Whilst methotrexate has been implicated in lung cancer, melanoma and non-Hodgkin lymphoma, overall safety data suggest any risk is quite low (e.g., EBV-associated lymphoproliferative disorders usually resolve with drug discontinuation). It is also a known chemotherapeutic agent. Anti-TNF treatment algorithms generally exclude patients with recent cancer. Rituximab, originally developed as a cancer drug, is not thought to affect risk of cancer development or progression. Treatment with disease-modifying therapy (conventional and biologics) is often withheld in patients with active malignancy undergoing chemotherapy due to a theo etical risk of potentiated immunosuppression and toxicity, particularly cytopaenias. However, maintaining arthritis control with glucocorticoids also has short- and long-term risks. Combining chemotherapy agents like carboplatin with methotrexate has been used for urothelial carcinoma and can be well tolerated with close monitoring of haematological parameters. Thus, it could be argued this patient is at risk of infections whichever treatment approach is taken and regaining control of arthritis with recommencement of methotrexate and rituximab is much better for her quality of life. Regular multidisciplinary discussions are important to outline risks versus benefits of combined treatment. This may be difficult in practice during staffing crises. Covid risk in patients receiving rituximab and/or chemotherapy, timing and response to COVID vaccination are also important considerations. Case report - Key learning points: . Primary peritoneal cancer is uncommon and can present as an incidental finding . Whilst treatment for progressive cancer is important, withholding rheumatoid arthritis treatment can have a significant adverse impact on quality of life . Morbidity and mortality risks of stopping treatment versus combined treatment (cancer therapy and disease-modifying therapy) ideally needs to be fully discussed and agreed with the patient and all care providers - lack of "named" providers, restructuring, redeployment, multi-specialty care and a global pandemic can make coordination of this difficult.

Consequences of the COVID-19 pandemic on the diagnosis and treatment of gastric cancer in referral centers in Italy.

BACKGROUND: The coronavirus pandemic had a major impact in Italy. The Italian health system's re-organization to face the emergency may have led to significant consequences especially in the diagnosis and treatment of malignancies. This study aimed to assess the impact of the pandemic in the diagnosis and treatment of gastric cancer in nine Gruppo Italiano RIcerca Cancro Gastrico (GIRCG) centers. METHODS: All patients assessed for gastric adenocarcinoma at nine GIRCG centers between January 2019 and November 2020 were included. Patients were grouped according to the date of "patient 1's" diagnosis in Italy: preCOVID versus COVID. Clinico-pathological and outcome differences between the two groups were analyzed. RESULTS: A total of 632 patients were included in the analysis (205 in the COVID group). The cT4 weighted ratios were higher in 2020 from April to September, with the greatest differences in May, August and September. The cM+ weighted ratio was significantly higher in July 2020. The mean number of gastrectomies had the greatest reduction in March and May 2020 compared with 2019. The median times from diagnosis to chemotherapy, to complete diagnostic work-up or to operation were longer in 2019. The median time from the end of chemotherapy to surgery was 17 days longer in the preCOVID group. CONCLUSIONS: A greater number of advanced or metastatic cases were diagnosed after the spread of SARS-CoV-2 infection, especially after the "full lockdown" periods. During the pandemic, once gastric cancer patients were referred to one of the centers, a shorter time to complete the diagnostic work-up or to address them to the best treatment option was required.

Bariatric surgeon perceptions of the safety of same-day sleeve gastrectomy in the state of Massachusetts.

BACKGROUND: During the past 2.5 years, select bariatric surgeons in the Commonwealth of Massachusetts have been implementing same-day sleeve gastrectomy (SDSG). Key reasons for this change have been to reduce risks associated with hospitalization in the context of the COVID-19 pandemic and to comply with third-party payer preference to reduce costs. OBJECTIVE: We aimed to evaluate bariatric surgeons' attitudes about outcomes and morbidity between patients who are hospitalized after sleeve gastrectomy and patients who undergo SDSG. SETTING: Beth Israel Deaconess Medical Center in Boston, Massachusetts (teaching hospital of Harvard Medical School). METHODS: This prospective cohort study was conducted among bariatric surgeons practicing in the Commonwealth of Massachusetts. An anonymous web-based questionnaire was distributed using the Research Electronic Data Capture software. A total of 58 bariatric surgeons in Massachusetts were identified and successfully contacted based on registration with the Massachusetts Board of Registration in Medicine, membership in the American Society for Metabolic and Bariatric Surgery, and internet search. RESULTS: A total of 33 bariatric surgeons in Massachusetts completed the survey, yielding a response rate of 56.9%. Among the respondents, 75.76% have not performed SDSG, reporting patient safety as the major concern, and 24.24% had performed SDSG in the past. CONCLUSION: Survey responses showed no significant differences in surgeon perception between SDSG and hospitalization after surgery. Optimal patient selection was an important factor influencing surgeons' decisions with regard to performing SDSG. However, bariatric surgeons in Massachusetts are reluctant to perform SDSG.

Ehealth Intervention Via Line Social Media as an Adjunct for Postoperative Care after Bariatric-Metabolic Surgery - Single Institution Experience

Background/Introduction: Applying eHealth interventions via social media is common in modern medicine. LINE is a popular communication app in Taiwan that can deliver messages 24 hours a day. In addition to being free-of-charge, it also allows bariatric nurses (BNs) and patients to enjoy bidirectional communication via telecommunication services instead of direct, face-to-face contact for patients undergoing bariatric-metabolic surgery (BMS). Objective(s): We conducted this retrospective study to determine the frequency and reasons for early post-discharge of LINE messages/calls and investigate the relationship between this frequency and contents of these messages and postoperative outcomes after BMS. Method(s): A retrospective review of prospectively collected data was conducted in an Asian weight management center. The study period ran from August 2016 to December 2021, and a total of 143 native patients with severe obesity were enrolled. All patients were informed of the necessity of a postoperative dietitian consultation before bariatric surgery. The patterns of LINE communication with the BN and associated actions to resolve patients' needs within 180 days after index BMS were analyzed. Result(s): Among the 143 enrolled patients, 100 underwent laparoscopic sleeve gastrectomy and 43 underwent laparoscopic Roux-en-Y gastric bypass. A total of 1,205 messages/calls were analyzed concomitantly;most LINE communications focused on diet problems (47.97%;n = 578), weight problems (11.54%;n = 139), and medications (9.21%;n = 111). Most problems could be resolved by LINE communications directly, and only a small portion (5.6%) was directed to local clinics or emergency departments. During the COVID-19 pandemic, the usage of LINE communications significantly increased (12.2 +/- 10.4 vs. 6.4 +/- 4.9;p < 0.01);nonetheless, a higher frequency of LINE communications would not hinder the regular clinic visits (r = 0.359;p = 0.01). Conclusion(s): Based on our limited experience, the LINE consultation service operated by the BN could effectively address patients' problems. Moreover, it might reduce the need for emergency department visits or unexpected clinic appointments for patients after BMS.

Making lemonade with lemons: a multicenter effort to improve outpatient sleeve gastrectomy amid the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic impacted healthcare delivery worldwide. Resource limitations prompted a multicenter quality initiative to enhance outpatient sleeve gastrectomy workflow and reduce the inpatient hospital burden. OBJECTIVES: This study aimed to determine the efficacy of this initiative, as well as the safety of outpatient sleeve gastrectomy and potential risk factors for inpatient admission. SETTING: A retrospective analysis of sleeve gastrectomy patients was conducted from February 2020 to August 2021. METHODS: Inclusion criteria were adult patients discharged on postoperative day 0, 1, or 2. Exclusion criteria were body mass index ≥60 kg/m2 and age ≥65 years. Patients were divided into outpatient and inpatient cohorts. Demographic, operative, and postoperative variables were compared, as well as monthly trends in outpatient versus inpatient admission. Potential risk factors for inpatient admission were assessed, as well as early Clavien-Dindo complications. RESULTS: Analysis included 638 sleeve gastrectomy surgeries (427 outpatient, 211 inpatient). Significant differences between cohorts were age, co-morbidities, surgery date, facility, operative duration, and 30-day emergency department (ED) readmission. Monthly frequency of outpatient sleeve gastrectomy rose as high as 71% regionally. An increased number of 30-day ED readmissions was found for the inpatient cohort (P = .022). Potential risk factors for inpatient admission included age, diabetes, hypertension, obstructive sleep apnea, pre-COVID-19 surgery date, and operative duration. CONCLUSION: Outpatient sleeve gastrectomy is safe and efficacious. Administrative support for extended postanesthesia care unit recovery was critical to successful protocol implementation for outpatient sleeve gastrectomy within this large multicenter healthcare system, demonstrating potential applicability nationwide.

The effect of the pandemic on the number of examined lymph nodes following major oesophophagogastric resection

Background: Lymph node yield following oesophagogastric (OG) cancer resection remains a valuable prognosticator of overall patient survival. It is also a quality indicator of histopathological assessment and a surrogate marker of surgical technique. The Royal College of Pathologists' state a minimum lymph node yield of 15 per specimen should obtained in 100% of cases where a radical OG resection has been undertaken. It is well known that the COVID-19 pandemic placed immense strain on NHS services. This study aimed to evaluate its effect on lymph node yield reporting following major OG resection in a large volume tertiary unit. Method(s): Retrospective National OG Cancer Audit (NOGCA) metrics were collected. Histological data including total lymph node yield and positive node status were extracted from patient records. Patient data was categorised into two study periods;pre-pandemic (March 2018-Feb 2020) and pandemic (March 2020- Feb 2022) following the first UK national lockdown. Comparative analysis between the two study periods was performed and for lymph node yield >15 per specimen a X2 statistic calculated. Result(s): In the pre COVID period a total of 280 (excluding GIST) resections were performed, 75% (210) oesophagectomies v. 25% (70) gastrectomies. The median age was 69 (range 25-90, males= 189 v. females =91). In the post pandemic period a total of 188 resections were performed, 72% (135) oesophagectomies v. 28% (53) gastrectomies. The median age was 69 (38-87, males = 142 v. female= 46). Lymph node yield was available for 275 resections in pre-pandemic study period, with a median nodal yield of 20 (5-61). In the pandemic study period lymph node yield data was available for 180 patients, median 19.5 (0-69). The minimum nodal yield (>15) was obtained in 80.7% of resection specimens pre-pandemic v. 68.9% in the pandemic study period (p= 0.00382). Conclusion(s): Our study demonstrates a higher rate of inadequate nodes examined in the post pandemic study period. Despite staffing pressures, efforts should be made to improve number of nodes examined to provide robust prognostic data.

Maintaining high volume oesophagagogastric resections during the COVID-19 pandemic: A single centres experience utilising the independent sector

Background: With many resources redirected to care for the those affected by the COVID-19 pandemic, the NHS faced unprecedented pressure to maintain oesophagogastric (OG) cancer resectional services. Our institution along with many tertiary units across the country were faced with limited access to essential critical care beds. The implementation of emergency contracts between the NHS and the independent sector (IS) allowed our unit to maintain a high volume resectional service by utilising the resources of a local private hospital with HDU/ ITU provision. We began operating within the IS shortly after the first UK lockdown in March 2020, and continued through till February 2022. During this period, we continued operating at our tertiary unit (TU) albeit at a reduced capacity. This study aimed to evaluate the surgical outcomes of patients undergoing major OG resectional surgery between the two sites. Method(s): This retrospective study included all patients who underwent major OG resectional surgery (including GIST) from March 2020-February 2022. Operation type and site were identified using OPCS-4 clinical codes and combined with National OG Cancer Audit (NOGCA) data to compare basic patient demographics, length of stay, complication rates, COVID infection rates and 90-day mortality. Descriptive and statistical analysis between the two operating sites was performed. Result(s): A total of 204 major OG resections were undertaken, 44% (89) at our TU;57 oesophagectomies and 32 gastrectomies, with 56% (115) at a local IS hospital;86 oesophagectomies and 29 gastrectomies. Additionally, 13 (6.4%) open and close procedures were performed across both sites. Median patient age was similar, 69 (45-86) years at our TU v. 68 (38-85) years at the IS site. A higher proportion of ASA 3 patients (46%) were operated on at our TU. No difference in median length of stay was observed;TU= 8 (1-93) days v. IS =9 (3-69) days, this included all patients who were repatriated to the TU. Higher complication rates seemed to occur in patients operated at the IS site v. the TU though these did not reach statistical significance;18 (15.7%) patients suffered an anastomotic leak v. 9 (10.1%) respectively (p= 0.246). 21 (18.3%) v. 13 (14.6%) patients suffered a major respiratory (p=0.487) and 4 (3.5%) v. 1 (1.1%) a major cardiac (p=0.281) complication. There were no cases of COVID infection within 30 days of primary procedure at the IS site, with 2 cases within the TU cohort. Our 90-day mortality rates were similar (IS= 4.54% v. TU=5.32%), p=0.661. Conclusion(s): Our study demonstrates that resection of patients with OG cancer is feasible in an independent sector hospital if supported by critical care. It allowed a high-volume tertiary unit to continue offering potentially curative surgery to patients whose treatment options would have otherwise been limited to oncological therapy only. Long term survival data compared to non-resecting trusts is required to determine whether this approach was superior. When considering future pandemic planning, we have demonstrated the value of this model in maintaining major OG resectional services.

Dynamic monitoring revealed a slightly prolonged waiting time for total gastrectomy during the COVID-19 pandemic without increasing the short-term complications.

We aimed to determine the pattern of delay and its effect on the short-term outcomes of total gastrectomy before and during the coronavirus disease 2019 (COVID-19) pandemic. Overlaid line graphs were used to visualize the dynamic changes in the severity of the pandemic, number of gastric cancer patients, and waiting time for a total gastrectomy. We observed a slightly longer waiting time during the pandemic (median: 28.00 days, interquartile range: 22.00-34.75) than before the pandemic (median: 25.00 days, interquartile range: 18.00-34.00; p = 0.0071). Moreover, we study the effect of delayed surgery (waiting time > 30 days) on short-term outcomes using postoperative complications, extreme value of laboratory results, and postoperative stay. In patients who had longer waiting times, we did not observe worse short-term complication rates (grade II-IV: 15% vs. 19%, p = 0.27; grade III-IV: 7.3% vs. 9.2%, p = 0.51, the short waiting group vs. the prolonged waiting group) or a higher risk of a longer POD (univariable: OR 1.09, 95% CI 0.80-1.49, p = 0.59; multivariable: OR 1.10, 95% CI 0.78-1.55, p = 0.59). Patients in the short waiting group, rather than in the delayed surgery group, had an increased risk of bleeding in analyses of laboratory results (plasma prothrombin activity, hemoglobin, and hematocrit). A slightly prolonged preoperative waiting time during COVID-19 pandemic might not influence the short-term outcomes of patients who underwent total gastrectomy.

Can revision of RYGB to sleeve gastrectomy be a solution to inadequate weight loss treatment?

We aimed to discuss the weight loss success of the revision of RYGB to sleeve gastrectomy (SG). Between January 2019 and June 2020, four patients' files were analyzed retrospectively. Post-RYGB mean minimal BMI was 27.4 ± 9.47 kg/m², before SG the mean BMI was 43.41 ± 4.16 kg/m2. Post-operative gastric fistula developed in two patients. The mean follow-up time after revision surgery was 17.25 ± 6.89 months, mean excess weight loss (EWL) was 74.77 ± 8.94%, and mean BMI was 32.65 ± 2.9 kg/m2. Despite high rate of major complications, revision of RYGB to SG is successful in weight loss and resolving certain complications of RYGB.

Nuestro objetivo era discutir el éxito en la pérdida de peso de la revisión de BGYR a gastrectomía en manga (SG). Entre enero de 2019 y junio de 2020, se analizaron retrospectivamente los archivos de cuatro pacientes. El IMC mínimo medio post BGYR fue 27.4 ± 9.47 kg/m², antes de SG el IMC medio fue 43.41 ± 4.16 kg/m2. En dos pacientes se desarrolló una fístula gástrica posoperatoria. El tiempo medio de seguimiento después de la cirugía de revisión fue de 17.25 ± 6.89 meses, la pérdida media de exceso de peso (PEP) fue de 74.77 ± 8.94% y el IMC medio fue de 32.65 ± 2.9 kg/m2. A pesar de la alta tasa de complicaciones mayores, la revisión de BGYR a SG tiene éxito en la pérdida de peso y la resolución de ciertas complicaciones de BGYR.

Effect of COVID 19 Lockdown on Weight Change in Post-Surgical Bariatric Patients

Katarina Bade Hartford CT CT1, Richard Seip Hartford CT1, Tara McLaughlin Vernon Rockville CT1, Darren Tishler Glastonbury CT1, Ilene Staff Hartford CT2, Connie Santana Glastonbury CT1, Aziz Benbrahim MERIDEN CT3, Meagan Moskowitz Meriden CT3, Pavlos Papasavas Hartford CT1 Hartford Hospital1 Hartford Hospital2 Mid State Medical Center3 Introduction: Safe and effective weight loss immediately following bariatric surgery occurs in concert with both social and medical support. Interruption of support networks may threaten weight loss. During the COVID19 pandemic, a Connecticut state-mandated “lockdown” from 3/15 to 5/18/2020 suspended in-person services and interrupted social support. We investigated the effect of exposure to 63 days of COVID lockdown within 12 months of index sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) on weight loss. Methods: This single center, retrospective chart review identified 1057 patients with 1 year follow-up data who underwent SG or RYGB from 1/9/2016 to 12/30/20. Controls (Group C) (SG n750, RYGB n130) completed surgery and follow up from 1/9/2016 to 3/15/20, before lockdown. Lockdown patients (Group L) (SG n159, RYGB n18) completed surgery before 3/15/20, and follow up after the lockdown (5/20/20 to 12/31/2020). Weight loss (WL) was compared between C and L, within surgery types. Results: Within surgery type, pre-surgery characteristics differed little between L and C (Table 1, top). Days to follow-up, and absolute and relative weight changes did not differ between L and C. Within L, 16% of SG patients and 20% of RYGB patients experienced virtual (telemedicine) visits with bariatric clinicians during follow-up, compared to 0.6% in Group C. Conclusion: We detected no effect of 63 days of COVID lockdown on measures of weight change at 1 year post SG or RYGB. Telemedicine visits may be useful to maintain/improve clinical management of surgical weight loss during suspension of live health services.
