ABSTRACT
Laparoscopic Roux-en-Y gastric bypass (RYGB) is crucial for significant weight reduction and treating obesity-related issues. However, the impact of gastrojejunostomy (GJ) anastomosis diameter on weight loss remains unclear. We investigate this influence on post-RYGB weight loss outcomes. A systematic search was conducted. Six studies met the inclusion criteria, showing varied GJ diameters and follow-up durations (1-5 years). Smaller GJ diameters generally correlated with greater short-to-medium-term weight loss, with a threshold beyond which complications like stenosis increased. Studies had moderate-to-low bias risk, emphasizing the need for precise GJ area quantification post-operation. This review highlights a negative association between smaller GJ diameters and post-RYGB weight loss, advocating for standardized measurement techniques. Future research should explore intra-operative and AI-driven methods for optimizing GJ diameter determination.

BACKGROUND: Metabolic bariatric surgery tourism continues to rise and has become a growing concern for bariatric surgeons globally. With varying degrees of regulation, counselling and success, those that develop complications may have to deal with a multitude of challenges often distant from their country of operation. The aim of this study was to characterize the barriers and facilitators influencing individuals to undergo metabolic bariatric surgery tourism, in order to better understand the implications to the National Health Service and other healthcare systems. METHODS: A systematic literature search, restricted to the English language, was performed to identify relevant studies. All studies were included until December 2022, the last search date. Study quality was assessed with the validated mixed-methods appraisal tool. A Braun and Clarke thematic analysis was undertaken to identify themes and subthemes. RESULTS: A total of five studies met the inclusion criteria. Identified themes included: availability, accessibility, cost, eligibility, reputation, and stigma; the available evidence was of varying quality. CONCLUSION: This work identifies a series of subthemes influencing the decision to undertake metabolic bariatric surgery tourism. The results highlight the limited literature available in understanding the complex motivational insights; the scale of the problem in the current healthcare system; cost and long-term outcomes. A National Emergency Bariatric Surgery audit would allow generation of more robust data to explore further the issues of clinical relationships and networks and to guide policy making.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) programs have been widely adopted in bariatric surgery. However, not all patients are successfully managed in the ERAS setting and there is currently little way of predicting the patients who will deviate from the program. Early identification of these patients could allow for more tailored protocols to be implemented preoperatively to address the issues, thereby improving patient outcomes. OBJECTIVES: The aim of this study was to elucidate the factors which preclude discharge by comparing patients who were successfully discharged by the end of the first postoperative day (POD 0/1) to those who stayed longer, including revisional surgery in this analysis. SETTING: A tertiary, high-volume Bariatric Centre, United Kingdom. METHODS: A retrospective analysis was performed of all patients undergoing bariatric surgery in a single centre in 1 year. Multivariate analyses compared patient and operative variables between patients who were discharged on POD 0/1 and those who stayed longer. RESULTS: A total of 288 bariatric operations were performed: 78% of operations performed were laparoscopic Roux-en-Y gastric bypass; 22% laparoscopic sleeve gastrectomy. Of these cases, 13% were revisional operations. Four patients returned to theatre on the index admission. 81% of patients were discharged by POD 0/1. A re-presentation within 30 days was seen in 6% of patients. There was no significant difference in length of stay for the type of operation performed (P = .86). Patients who had a revisional procedure were not more likely to stay longer. Length of stay was also independent of age, BMI, and comorbidities. Caucasian patients were more likely to be discharged on POD 0/1 than those of other ethnicities (90% versus 78%; P = .02). Operations performed by trainee surgeons, under consultant supervision, were significantly more likely to be discharged on POD 0/1 (P = .03). However, a logistic regression analysis was unable to predict patients who had a prolonged stay. CONCLUSIONS: Patient length of stay is independent of BMI, operation, and comorbidities and these factors do not need special consideration in ERAS pathways. Patients undergoing revisional procedures can be managed in the same way as those having primary procedures, with a routine POD 0/1 discharge. However, the impact of individual patient factors, and their interaction, is complex and cannot predict overstay.

The aim of this meta-analysis was to compare the effects of LRYGB and LSG on dyslipidemia. Studies comparing the effects of LRYGB and LSG on dyslipidemia with follow-up of 12 months or more were included. Twenty-four studies comprising seven RCTs and 17 comparative observational studies were included. Meta-analysis of RCTs (n=487) showed that improvement/resolution of dyslipidemia was better after LRYGB (68.5%, n=161/235) compared to LSG (48.4%, n=122/252). Patients undergoing LRYGB were more than twice as likely to experience improvement/resolution in dyslipidemia compared to those undergoing LSG (OR 2.28, 95% CI 1.21-4.29, p=0.010). Both LRGYB and LSG appears effective in improving dyslipidemia at >12 months after surgery; however, this improvement is more than twice higher after LRYGB compared to LSG.

Obesity has reached pandemic levels globally. Surgical management of obesity aims to establish metabolic control, weight loss and resolution of multiple health conditions and to improve quality of life. Here, we examine the role of surgery in the management of obesity within the context of a multidisciplinary team involving a variety of healthcare professionals. We highlight the importance of patient selection, perioperative care, the various types of bariatric surgery currently available as well as emerging procedures. In addition to clarifying the different types of procedure, we also examine the potential complications and issues of weight regain and failure to lose weight. Ultimately, bariatric surgery remains comparatively safe and with generally excellent results in terms of control of existing obesity-related conditions; with the ever-increasing number of patients living with obesity, the scope of bariatric surgery is thus likely to increase.

Renal vascular hypertension is a diagnosis that needs to be entertained in the setting of refractory, otherwise unexplained hypertension in pregnancy. Conclusive diagnosis of the condition is made by the use of angiography, which confers only a low, safe dose of radiation to the fetus, especially after the first trimester. Percutaneous angioplasty is effective in treating this condition and is best performed postnatally to avoid fetal exposure to ionising radiation. While it could be managed pharmacologically, more refractory cases in pregnancy may be offered interventional treatment.

The laparoscopic approach for dealing with bariatric complications has become the gold standard of modern practice. The aim of this study is to assess the role of relaparoscopy as a diagnostic and therapeutic approach towards managing complications and improving 30-day outcome. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database was conducted in a tertiary bariatric unit. Data were collected on all bariatric surgical procedures performed between March 2013 and March 2019. Any patient who was returned to theatre for a suspected serious complication was identified and their outcome studied. RESULTS: Over the 5-year study period, the total number of operations performed was 1660 (981 laparoscopic gastric bypass (LRYGB), 612 laparoscopic sleeve gastrectomy (LSG) and 67 revisional bariatric operations). Early postoperative complications (in hospital or within 30 days of surgery) that lead to reoperation were recorded in 33 patients (1.9%). These complications occurred after LRYGB in 26 patients (2.65%) and LSG in 7 patients (1.14%), respectively. Anastomotic leaks occurred in 1.1% of LRYGB, whilst 0.6% of patients have jejuno-jejunostomy obstruction. Obstruction at the gastro-jejunostomy anastomosis occurred in one patient. Following LSG, one mortality was recorded following bleeding from the staple line (0.06%) and five patients (0.3%) had leaks from the staple line. Thirty-one reoperations were performed laparoscopically, and two were converted to the open approach, whilst 2 operations were planned as open from the outset. CONCLUSION: Relaparoscopy is an effective and safe approach to the management of clinically or radiologically suspected early complications after bariatric surgery. Graphical abstract.

SARS-CoV-2 is a virus that is the cause of a serious life-threatening disease known as COVID-19. It was first noted to have occurred in Wuhan, China in November 2019 and the WHO reported the first case on December 31, 2019. The outbreak was declared a global pandemic on March 11, 2020 and by May 30, 2020, a total of 5 899 866 positive cases were registered including 364 891 deaths. SARS-CoV-2 primarily targets the lung and enters the body through ACE2 receptors. Typical symptoms of COVID-19 include fever, cough, shortness of breath and fatigue, yet some atypical symptoms like loss of smell and taste have also been described. 20% require hospital admission due to severe disease, a third of whom need intensive support. Treatment is primarily supportive, however, prognosis is dismal in those who need invasive ventilation. Trials are ongoing to discover effective vaccines and drugs to combat the disease. Preventive strategies aim at reducing the transmission of disease by contact tracing, washing of hands, use of face masks and government-led lockdown of unnecessary activities to reduce the risk of transmission.

What started as a cluster of patients with a mysterious respiratory illness in Wuhan, China, in December 2019, was later determined to be coronavirus disease 2019 (COVID-19). The pathogen severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel Betacoronavirus, was subsequently isolated as the causative agent. SARS-CoV-2 is transmitted by respiratory droplets and fomites and presents clinically with fever, fatigue, myalgias, conjunctivitis, anosmia, dysgeusia, sore throat, nasal congestion, cough, dyspnea, nausea, vomiting, and/or diarrhea. In most critical cases, symptoms can escalate into acute respiratory distress syndrome accompanied by a runaway inflammatory cytokine response and multiorgan failure. As of this article's publication date, COVID-19 has spread to approximately 200 countries and territories, with over 4.3 million infections and more than 290,000 deaths as it has escalated into a global pandemic. Public health concerns mount as the situation evolves with an increasing number of infection hotspots around the globe. New information about the virus is emerging just as rapidly. This has led to the prompt development of clinical patient risk stratification tools to aid in determining the need for testing, isolation, monitoring, ventilator support, and disposition. COVID-19 spread is rapid, including imported cases in travelers, cases among close contacts of known infected individuals, and community-acquired cases without a readily identifiable source of infection. Critical shortages of personal protective equipment and ventilators are compounding the stress on overburdened healthcare systems. The continued challenges of social distancing, containment, isolation, and surge capacity in already stressed hospitals, clinics, and emergency departments have led to a swell in technologically-assisted care delivery strategies, such as telemedicine and web-based triage. As the race to develop an effective vaccine intensifies, several clinical trials of antivirals and immune modulators are underway, though no reliable COVID-19-specific therapeutics (inclusive of some potentially effective single and multi-drug regimens) have been identified as of yet. With many nations and regions declaring a state of emergency, unprecedented quarantine, social distancing, and border closing efforts are underway. Implementation of social and physical isolation measures has caused sudden and profound economic hardship, with marked decreases in global trade and local small business activity alike, and full ramifications likely yet to be felt. Current state-of-science, mitigation strategies, possible therapies, ethical considerations for healthcare workers and policymakers, as well as lessons learned for this evolving global threat and the eventual return to a "new normal" are discussed in this article.
ABSTRACT
INTRODUCTION: Literature on long-term (> 10 years) outcomes in terms of weight loss, resolution of co-morbidities, and quality of life (QoL) after bariatric surgery is limited. The aim of this study was to investigate the excess weight loss (EWL), resolution of comorbidities, and QoL more than 10 years after laparoscopic Roux-en-Y gastric bypass (LRYGB) using the Bariatric Analysis and Reporting Outcome System (BAROS). METHODS: Data on patient demographics, weight, body mass index (BMI), comorbidities, type of surgery, complications, and QoL were collected from a prospectively maintained database. RESULTS: A total of 92 patients out of 104 who underwent LRYGB during the study period and completed a median follow-up of 130 months were successfully contacted. The median age was 48 years (IQR 42-54 years) and 85.9% had a BMI of more than 40. The median excess weight loss (EWL) was 46.5% (IQR 27.9-64.3%). Type 2 diabetes mellitus reduced from 56.5 to 23.9% (p < 0.001), hypertension from 51.1 to 39.1% (p = 0.016), and obstructive sleep apnoea from 33.7 to 12.0% (p < 0.001). Participants reported feeling better (median 0.2, IQR 0.2-0.4), engaging in more physical activity (0.1, IQR 0.1-0.3), having more satisfactory social contacts (0.4, IQR 0.2-0.5), a better ability to work (0.3, IQR - 0.1-0.5), and a healthier approach to food (0.2, IQR - 0.3-0.3) at the end of follow-up. CONCLUSION: LRYGB leads to positive outcomes in terms of weight loss, reduction in comorbidities, and improvement in QoL at a follow-up of more than 10 years.

BACKGROUND: Obesity is associated with a twofold risk of gastroesophageal reflux disease (GERD) and thrice the risk of Barrett's esophagus (BE). Roux-en-Y gastric bypass (RYGB) leads to weight loss and improvement of GERD in population with obesity, but its effect on BE is less clear. METHODS: Bibliographic databases were searched systematically for relevant articles till January 31, 2019. Studies evaluating the effect of RYGB on BE with preoperative and postoperative endoscopy and biopsy were included. Study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) tool. Meta-analysis was conducted using Mantel-Haenszel, random effects model and presented as risk difference (RD) or odds ratio (OR) with 95% confidence intervals. RESULTS: Eight studies with 10,779 patients undergoing RYGB reported on 117 patients with BE with follow-up of > 1 year. Significant regression of BE after RYGB was observed (RD - 0.56.95% c.i. - 0.69 to - 0.43; P < 0.001). Subgroup analysis showed regression of both short-segment BE [ssBE] (RD - 0.51.95% c.i. - 0.68 to - 0.33; P < 0.001) and long-segment BE [lsBE] (RD - 0.46.95% c.i. - 0.71 to - 0.21; P < 0.001). RYGB also caused improvement in GERD in patients of BE (RD - 0.93, 95% c.i. - 1.04 to - 0.81; P < 0.001). RYGB was strongly associated with regression of BE compared with progression (OR 31.2.95% c.i. 11.37 to 85.63; P < 0.001). CONCLUSIONS: RYGB leads to significant improvement of BE at > 1 year after surgery in terms of regression and resolution of the associated GERD. Both ssBE and lsBE improve after RYGB significantly.

Mononuclear MnIII-hydroxo and dinuclear (µ-oxo)dimanganese(III,III) complexes were prepared using derivatives of the pentadentate, amide-containing dpaq ligand (dpaq = 2-[bis(pyridin-2-ylmethyl)]amino- N-quinolin-8-yl-acetamidate). Each of these ligand derivatives (referred to as dpaq5R) contained a substituent R (where R = OMe, Cl, and NO2) at the 5-position of the quinolinyl group. Generation of the MnIII complexes was achieved by either O2 oxidation of MnII precursors (for [MnII(dpaq5OMe)]+ and [MnII(dpaq5Cl)]+ or PhIO oxidation (for [MnII(dpaq5NO2)]+). For each oxidized complex, 1H NMR experiments provided evidence of a water-dependent equilibrium between paramagnetic [MnIII(OH)(dpaq5R)]+ and an antiferromagnetically coupled [MnIIIMnIII(µ-O)(dpaq5R)2]2+ species in acetonitrile, with the addition of water favoring the MnIII-hydroxo species. This conversion could also be monitored by electronic absorption spectroscopy. Solid-state X-ray crystal structures for each [MnIIIMnIII(µ-O)(dpaq5R)2](OTf)2 complex revealed a nearly linear Mn-O-Mn core (angle of ca. 177°), with short Mn-O distances near 1.79 Å, and a Mn···Mn separation of 3.58 Å. X-ray crystallographic information was also obtained for the mononuclear [MnIII(OH)(dpaq5Cl)](OTf) complex, which has a short Mn-O(H) distance of 1.810(2) Å. The influence of the 5-substituted quinolinyl moiety on the electronic properties of the [MnIII(OH)(dpaq5R)]+ complexes was demonstrated through shifts in a number of 1H NMR resonances, as well as a steady increase in the MnIII/II cyclic voltammetry peak potential in the order [MnIII(OH)(dpaq5OMe)]+ < [MnIII(OH)(dpaq)]+ < [MnIII(OH)(dpaq5Cl)]+ < [MnIII(OH)(dpaq5NO2)]+. These changes in oxidizing power of the MnIII-hydroxo adducts translated to only modest rate enhancements for TEMPOH oxidation by the [MnIII(OH)(dpaq5R)]+ complexes, with the most reactive [MnIII(OH)(dpaq5NO2)]+ complex showing a second-order rate constant only 9-fold larger than that of the least reactive [MnIII(OH)(dpaq5OMe)]+ complex. These modest rate changes were understood on the basis of density functional theory (DFT)-computed p Ka values for the corresponding [MnII(OH2)(dpaq5R)]+ complexes. Collectively, the experimental and DFT results reveal that the 5-substituted quinolinyl groups have an inverse influence on electron and proton affinity for the MnIII-hydroxo unit.
ABSTRACT
BACKGROUND: Primary care practitioners (PCP) are the "gate-keepers" for publicly funded weight loss surgery (WLS) in the United Kingdom, but their attitude toward WLS has not been studied to date. OBJECTIVE: This pilot study aimed to investigate opinions and experience of PCPs regarding WLS in the United Kingdom. SETTING: PCPs from 3 publicly funded primary care consortiums from distinct geographic areas within the United Kingdom were surveyed. METHODS: A cross-sectional survey approach was used to assess PCP attitude to WLS surgery. A questionnaire was sent electronically to PCPs, designed to assess PCP demographic, experience, knowledge, and attitude regarding obesity and WLS. For the purposes of analysis, PCPs were divided into junior and senior based on duration of practice. RESULTS: Of PCPs, 35 completed and returned the questionnaire. Although PCPs stated that approximately 30% of their patients were obese, 17 (49%) had made not a single referral for WLS in the previous 12 months. PCPs overestimated early WLS mortality rate more than 10-fold and 23 (66%) did not feel confident providing care to patients post-WLS. Junior PCPs were significantly more likely to feel that WLS should not be publicly funded (P = .01). CONCLUSIONS: These findings suggest a prejudice against WLS amongst PCPs in England, particularly among junior doctors.

OBJECTIVE: Laparoscopy is increasingly being used as an alternative to open surgery in the treatment of patients with colon cancer. The study objective is to estimate the difference in hospital costs between laparoscopic and open colon cancer surgery. DESIGN: Population-based retrospective cohort study. SETTINGS: All acute hospitals of the National Health System in England. POPULATION: A total of 55â 358 patients aged 30 and over with a primary diagnosis of colon cancer admitted for planned (elective) open or laparoscopic major resection between April 2006 and March 2013. PRIMARY OUTCOMES: Inpatient hospital costs during index admission and after 30 and 90â days following the index admission. RESULTS: Propensity score matching was used to create comparable exposed and control groups. The hospital cost of an index admission was estimated to be £1933 (95% CI 1834 to 2027; p<0.01) lower among patients who underwent laparoscopic resection. After including the first unplanned readmission following index admission, laparoscopy was £2107 (95% CI 2000 to 2215; p<0.01) less expensive at 30â days and £2202 (95% CI 2092 to 2316; p<0.01) less expensive at 90â days. The difference in cost was explained by shorter hospital stay and lower readmission rates in patients undergoing minimal access surgery. The use of laparoscopic colon cancer surgery increased 4-fold between 2006 and 2012 resulting in a total cost saving in excess of £29.3 million for the National Health Service (NHS). CONCLUSIONS: Laparoscopy is associated with lower hospital costs than open surgery in elective patients with colon cancer suitable for both interventions.

OBJECTIVE: To determine the difference in in-hospital mortality and length of hospital stay (LOS) after esophagectomy between the United States and England. BACKGROUND: Since 2001, complex procedures such as esophagectomy have been centralized in England, but in the United States no formal plan for centralization exists. METHODS: Patients who underwent esophagectomy for cancer between 2005 and 2010 were identified from the Nationwide Inpatient Sample (United States) and the Hospital Episodes Statistics (England). In-hospital mortality and LOS were compared. RESULTS: There were 7433 esophagectomies performed in 66 English hospitals and 5858 resections in 775 US hospitals; median number of resections per center per year was 17.5 in England and 2 in the United States. In-hospital mortality was greater in US hospitals (5.50% vs 4.20%, P = 0.001). In multiple regression analysis, predictors of mortality included patient age, comorbidities, hospital volume, and surgery performed in the United States [odds ratio (OR) = 1.20 (1.02-1.41), P = 0.03]. Median LOS was greater in the English hospitals (15 vs 12 days, P < 0.001). However, when subset analysis was done on high-volume centers in both health systems, mortality was significantly better in US hospitals (2.10% vs 3.50%, P = 0.02). LOS was also seen to decrease in the US high-volume centers but not in England. CONCLUSIONS: The findings from this international comparison suggest that centralization of high-risk cancer surgery to centers of excellence with a high procedural volume translates into an improved clinical outcome. These findings should be factored into discussions regarding future service configuration of major cancer surgery in the United States.

BACKGROUND: Patients with positive peritoneal cytology from oesophagogastric cancer have a poor prognosis. The purpose of this study was to compare lavage cytology from the pelvis alone with the pelvis and subphrenic areas at staging laparoscopy in patients with potentially resectable oesophagogastric adenocarcinoma. METHODS: Between November 2006 and November 2010, all patients with operable oesophagogastric adenocarcinoma on spiral CT considered fit for surgical resection underwent staging laparoscopy. Subphrenic and pelvic peritoneal lavage for cytology was performed followed by laparoscopic biopsy of any visible peritoneal disease. Patients were divided into groups: macroscopic peritoneal metastases (P+), no macroscopic peritoneal disease with negative cytology (P-C-), no macroscopic peritoneal disease with positive pelvic cytology (P-PC+), no macroscopic peritoneal disease with positive subphrenic cytology (P-SC+), or both (P-PSC+). RESULTS: A total of 316 staging laparoscopy procedures were performed; 245 patients (78 %) were P-C-, 28 (9 %) were P+, and 43 (14 %) were P-C+, of whom 29 (9 %) were P-PSC+, 10 (3 %) were P-SC+, and 4 (1 %) were P-PC+. Pelvic cytology alone had 76.7 % sensitivity for peritoneal disease, and subphrenic cytology alone had 90.7 % sensitivity. CONCLUSIONS: Peritoneal lavage for cytology at staging laparoscopy has an incremental benefit for staging oesophagogastric adenocarcinoma in the absence of macroscopic metastatic disease. Subphrenic washings have the highest yield of positive results. Performing isolated pelvic washings for cytology will understage 23.3 % of patients with microscopic peritoneal disease. The routine use of subphrenic in combination with pelvic lavage for cytology at staging laparoscopy in patients with oesophagogastric adenocarcinoma has an incremental benefit in detecting cytology-positive disease over either pelvic or subphrenic cytology alone.

Current serological evidence suggests the presence of scrub typhus and spotted fever group (SFG) rickettsiosis in Sri Lanka. Our objective was to identify rickettsial agents/Q fever as aetiological causes for patients who were presumed having rickettsioses by the presence of an eschar or a rash. Sera from patients with unknown origin fever from Matara were tested by immunofluorescence for SFG rickettsial antigens, typhus group rickettsiae, Orientia tsutsugamushi, and Coxiella burnetii antigens. Thirteen (7.3%) of the patients presented with a rash, 11 (6.1%) had an inoculation eschar, and 16 patients recalled a tick or flea bite. We found that 25 (14%) patients had scrub typhus, 6 (3%) SFG rickettsioses, 3 (1.6%) acute Q fever, 3 (1.6%) murine typhus, and 3 (1.6%) were infected by Rickettsia felis. In addition to already described scrub and murine typhus, we found that R. felis and C. burnetii infections should be considered in Sri Lanka.
