RESUMO
PURPOSE: Laparoscopic cholecystectomy, introduced in 1985 by Prof. Dr. Erich Mühe, has become the gold standard for treating chronic symptomatic calculous cholecystopathy and acute cholecystitis, with an estimated 750,000 procedures performed annually in the United States of America. The risk of iatrogenic bile duct injury persists, ranging from 0.2 to 1.3%. Risk factors include male gender, obesity, acute cholecystitis, previous hepatobiliary surgery, and anatomical variations in Calot's triangle. Strategies to mitigate bile duct injury include the Critical View of Safety and fundus-first dissection, along with intraoperative cholangiography and alternative approaches like subtotal cholecystectomy. METHODS: This paper introduces the shoeshine technique, a maneuver designed to achieve atraumatic exposure of anatomical structures, local hemostatic control, and ease of infundibulum mobilization. This technique involves the use of a blunt dissection tool and gauze to create traction and enhance visibility in Calot's triangle, particularly beneficial in cases of severe inflammation. Steps include using the critical view of safety and Rouviere's sulcus line for orientation, followed by careful dissection and traction with gauze to maintain stability and reduce the risk of instrument slippage. RESULTS: The technique, routinely used by the authors in over 2000 cases, has shown to enhance patient safety and reduce bile duct injury risks. CONCLUSION: The shoeshine technique represents a simple and easy way to apply maneuver that can help surgeon during laparoscopic cholecystectomies exposing the hepatocystic area and promote blunt dissection.

Primary biliary tract tumors are malignancies that originate in the liver, bile ducts, or gallbladder. These tumors often present with jaundice of unknown etiology, leading to delayed diagnosis and advanced disease. Currently, several palliative treatment options are available for primary biliary tract tumors. They include percutaneous transhepatic biliary drainage (PTBD), biliary stenting, and surgical interventions such as biliary diversion. Systemic therapy is also commonly used for the palliative treatment of primary biliary tract tumors. It involves the administration of chemotherapy drugs, such as gemcitabine and cisplatin, which have shown promising results in improving overall survival in patients with advanced biliary tract tumors. PTBD is another palliative treatment option for patients with unresectable or inoperable malignant biliary obstruction. Biliary stenting can also be used as a palliative treatment option to alleviate symptoms in patients with unresectable or inoperable malignant biliary obstruction. Surgical interventions, such as biliary diversion, have traditionally been used as palliative options for primary biliary tract tumors. However, biliary diversion only provides temporary relief and does not remove the tumor. Primary biliary tract tumors often present in advanced stages, making palliative treatment the primary option for improving the quality of life of patients.
RESUMO
BACKGROUND: Cytokine storm is a marker of severity and severe mortality in patients with coronavirus disease 2019 (COVID-19) pneumonia. Immunomodulatory treatments may reduce morbidity and mortality. OBJECTIVES: To determine whether a 7-day course of methylprednisolone (MP) administered with and without tocilizumab improves outcomes in patients with severe COVID-19 (SARS-CoV-2) pneumonia requiring oxygen therapy, relative to historical controls. STUDY DESIGN AND METHOD: In this randomized controlled study, patients hospitalized with severe COVID-19 at Rashid Hospital, Dubai, in June 2020 were randomized 1:1 to receive intravenous MP (40 mg twice daily for 7 days) with or without a single dose of intravenous tocilizumab (400 mg). While data from the control arm, consisting of patients administered usual care, were obtained through retrospective review of their electronic medical records. The patients in the three arms were matched by disease severity and inclusion and exclusion criteria. The primary outcomes were day 45 all-cause mortality after randomization, rate of admission to the intensive care unit (ICU), length of ICU stay, days on ventilators, and length of hospital stay. RESULTS: In total, 76 patients were recruited, including 23 treated with MP, 26 with MP plus tocilizumab, and 27 historical controls. The rates of admission to the ICU and invasive mechanical ventilation were lowest in patients treated with MP alone, with the rates in this group being significantly lower than the rates in the control group (p = 0.04). Time on a ventilator was lowest in the MP group (1.09 ± 3.68 days) and highest in the control group (7.93 ± 14.86 days). The number of days in the ICU was significantly lower in the MP group than in the control and MP plus tocilizumab groups (p = 0.043). One patient (4.3%) in the MP group and five (18.5%) in the control arm died within 45 days. Survival was highest in patients treated with MP alone, with the addition of tocilizumab not improving survival or any of the other outcomes significantly. INTERPRETATION/CONCLUSION: In patients with severe COVID-19 pneumonia on oxygen support, administration of MP daily for 7 days had reduced mortality at 45 days and was associated with significantly lower ICU admission and ventilation rates compared with usual. Adding tocilizumab to MP did not improve any of the studied outcomes significantly.

INTRODUCTION: Routine use of preoperative abdominal ultrasound for patients undergoing bariatric surgery is controversial. Despite that some physicians routinely implement it, others consider it unnecessary and not cost effective because it does not have a clear clinical significance in the preparation of bariatric patients. AIM OF THE STUDY: To investigate whether routine abdominal ultrasound prior to bariatric surgery affects the surgical plan or not. PATIENTS AND METHODS: We reviewed medical records of patients with abdominal ultrasound before bariatric surgery in Rashid Hospital between June 2014 and December 2016. Patients were divided into four groups: group 0 included patients with normal abdominal ultrasound, group 1 included abnormalities that did not affect timing or type of procedure, group 2 included findings that did not affect surgical plan but needed postoperative follow-up, and group 3 included abnormalities that had a direct impact on the procedure. RESULTS: One thousand one hundred twenty files were reviewed. Results were missing in 183 files, thus excluded; remaining 937 files were included. Mean age of patients was 37 ± 12 years, 589 (63%) were females and 348 (37%) were males. Mean BMI was 45.1 ± 9.8 kg/m2. Ultrasound was normal in 354 (37.7%) of patients and abnormal in 583 (62.3%). CONCLUSION: Routine abdominal ultrasound does not seem to have an important part in preoperative preparation of patients before bariatric surgery. Further studies could be helpful in discussing this role and building up clear solid evidence and guidelines that could be approved by international bariatric associations regarding the indication of preoperative abdominal ultrasound before bariatric surgery.

BACKGROUND: Workforce planning is critical for being able to deliver appropriate health service and thus is relevant to medical education. It is, therefore, important to understand medical students' future specialty choices and the factors that influence them. This study was conducted to identify, explore, and analyze the factors influencing specialty preferences among medical students of the United Arab Emirates (UAE). METHODS: A multiyear, multicenter survey of medical student career choice was conducted with all five UAE medical schools. The questionnaire consisted of five sections. Chi-squared tests, regression analysis, and stepwise logistic regression were performed. RESULTS: The overall response rate was 46% (956/2079). Factors that students reported to be extremely important when considering their future career preferences were intellectual satisfaction (87%), work-life balance (71%), having the required talent (70%), and having a stable and secure future (69%). The majority of students (60%) preferred internal medicine, surgery, emergency medicine, or family Medicine. The most common reason given for choosing a particular specialty was personal interest (21%), followed by flexibility of working hours (17%). DISCUSSION: The data show that a variety of factors inspires medical students in the UAE in their choice of a future medical specialty. These factors can be used by health policymakers, university mentors, and directors of residency training programs to motivate students to choose specialties that are scarce in the UAE and therefore better serve the health-care system and the national community.
