Factors affecting duration of stay in the intensive care unit after coronary artery bypass surgery and its impact on in-hospital mortality: a retrospective study.

BACKGROUND: Different risk factors affect the intensive care unit (ICU) stay after cardiac surgery. This study aimed to evaluate these risk factors. PATIENTS AND METHODS: A retrospective analysis was conducted on clinical, operative, and outcome data from 1070 patients (mean age: 59 ± 9.8 years) who underwent isolated coronary bypass grafting CABG surgery with cardiopulmonary bypass. The outcome variable was prolonged length of stay LOS in the CICU stay (> 3 nights after CABG). RESULTS: Univariate predictors of prolonged ICU stays included a left atrial diameter of > 4 cm (P < 0.001),chronic obstructive airway disease COPD (P = 0.005), hypertension (P = 0.006), diabetes mellitus (P = 0.009), having coronary stents (P = 0.006), B-blockers use before surgery (either because the surgery was done on urgent or emergency basis or the patients have contraindication to B-blockers use) (P = 0.005), receiving blood transfusion during surgery (P = 0.001), post-operative acute kidney injury (AKI) (P < 0.001), prolonged inotropic support of > 12 h (P < 0.001), and ventilation support of > 12 h (P < 0.001), post-operative sepsis or pneumonia (P < 0.001), post-operative stroke/TIA (P = 0.001), sternal wound infection (P = 0.002), and postoperative atrial fibrillation POAF (P < 0.001). Multivariate regression revealed that patients with anleft atrial LA diameter of > 4 cm (AOR 2.531, P = 0.003), patients who did not take B-blockers before surgery (AOR 1.1 P = 0.011), patients on ventilation support > 12 h (AOR 3.931, P = < 0.001), patients who developed pneumonia (AOR 20.363, P = < 0.001), and patients who developed post-operative atrial fibrillation (AOR 30.683, P = < 0.001) were more likely to stay in the ICU for > 3 nights after CABG. CONCLUSION: Our results showed that LA diameter > 4 cm, patients who did not take beta-blockers before surgery, on ventilation support > 12 h, developed pneumonia post-operatively, and developed POAF were more likely to have stays lasting > 3 nights. Efforts should be directed toward reducing these postoperative complications to shorten the duration of CICU stay, thereby reducing costs and improving bed availability.

The impact of partial and complete lockdown during the COVID-19 pandemic on acute surgical services: a retrospective cohort study.

PURPOSE: The burden of the coronavirus disease of 2019 (COVID-19) pandemic on the healthcare sector has been overwhelming, leading to drastic changes in access to healthcare for the public. We aimed to establish the impact of implemented government partial and complete lockdown policies on the volume of surgical patient admissions at a tertiary referral center during the pandemic. METHODS: A database was retrospectively created from records of patients admitted to the surgical ward through the emergency department. Three 6-week periods were examined: The complete lockdown period (CLP), which included a ban on the use of cars with the exception of health service providers and essential sector workers; A pre-COVID period (PCP) 1 year earlier (no lockdown); and a partial lockdown period (PLP) that involved a comprehensive curfew and implementing social distancing regulations and wear of personal protective equipment (e.g., masks) in public places. RESULTS: The number of patients admitted to the surgery ward was significantly higher in the PCP cohort compared to the CLP and PLP cohorts (p = 0.009), with a 42.1% and 37% decline in patients' admissions, respectively. Admission rates for patients with biliary pathologies and vascular thrombotic events increased. 30-day mortality rates did not differ significantly between the three periods (p = 0.378). CONCLUSIONS: While COVID-19 lockdown regulations had a significant impact on patient admission rates, surgical outcomes were not affected and the standards of care were maintained. Future protocols should strive to improve access to healthcare to avoid complications caused by delayed diagnosis and treatment.

The clinical elective course and its effects on medical students and graduates of Jordanian medical schools.

BACKGROUND: The elective course is part of the 6th-year medical school curriculum in Jordan. Students choose the specialty in which they wish to spend 8 weeks and choose their location even if it is outside their university's affiliated hospitals. In this study, we try to understand student choices regarding the country of elective, chosen specialty, type of placement (observership/clerkship), and elective general value from participants' perspectives. METHODS: This paper used a cross-sectional study. The survey was distributed through social media platforms (mainly Facebook and WhatsApp) targeting 6th-year medical students and doctors who graduated from one of the 5 Jordanian medical schools (the University of Jordan, Jordan University of Science and Technology, Mutah University, Yarmouk University, and Hashemite University). RESULTS: The majority of participants had an international elective (69.6%), mainly in the USA, followed by the UK. Internal medicine was the primary field of interest for 14.8%, followed by general surgery. Of these, 241 (62.6%) actively participated in work at their chosen hospitals as they had a clerkship/hands-on experience. In contrast, 142 (36.9%) were observers. The majority indicated that the elective is worth the time, money, and effort. Moreover, they had adequate supervision throughout the course and could achieve their preset objectives. CONCLUSIONS: The elective course gives a unique experience to our students. General satisfaction is an indicator of the success of the course in actively exposing medical students to clinical practice.

The Effect of COVID 19 on Liver Parenchyma Detected and measured by CT scan Hounsfield Units.

Background: COVID 19 may affect organs other than lungs, including liver, leading to parenchymal changes. These changes are best assessed by unenhanced computed tomography (CT). We aim to investigate the effect of COVID 19 on liver parenchyma by measuring the attenuation in CT scan Hounsfield unit (HU). Materials and Methods: A cohort of patients, who tested COVID 19 polymerase chain reaction positive, were enrolled and divided into two groups: fatty liver (FL) group (HU ≤ 40) and nonfatty liver (NFL) group (HU > 40) according to liver parenchyma attenuation measurements by high resolution noncontrast CT scan. The CT scan was performed on admission and on follow up (10-14 days later). Liver enzyme tests were submitted on admission and follow up. Results: Three hundred and two patients were enrolled. Liver HU increased significantly from 48.9 on admission to 53.4 on follow up CT scan (P<0.001) in all patients. This increase was more significant in the FL group (increased from 31.9 to 42.9 [P =0.018]) Liver enzymes were abnormal in 22.6% of the full cohort. However, there was no significant change in liver enzymes between the admission and follow up in both groups. Conclusion: The use of unenhanced CT scan for assessment of liver parenchymal represents an objective and noninvasive method. The significant changes in parenchymal HU are not always accompanied by significant changes in liver enzymes. Increased HU values caused by COVID 19 may be due to either a decrease in the fat or an increase in the fibrosis in the liver.

Migrated Inferior Vena Cava (IVC) Filter Strut: A Rare Cause of Chronic Distal Pancreatitis with Likely Malignant Transformation.

BACKGROUND Inferior vena cava (IVC) filters are indicated for patients with recurrent venous thrombosis despite proper anticoagulation or whenever anticoagulation is contraindicated. IVC filter deployment is an invasive procedure with various complications. One example is IVC filter limb fracture and migration, which is associated with significant morbidity and/or mortality. Extravascular migration toward pancreas may induce pancreatitis. Patients with chronic pancreatitis are known to have an increased risk of pancreatic malignancy. CASE REPORT We report an extremely rare case of IVC filter fractured limb in 44-year-old woman, which had migrated into the pancreatic tail and manifested as chronic distal pancreatitis. A pancreatic adenocarcinoma was found by biopsy at the pancreas tail. It is likely that a foreign body promoted this metaplasia and neoplastic transformation. CONCLUSIONS Early detection and retrieval of a displaced foreign body in organs, such as the pancreas, seem to be essential to reduce risk of subsequent complications, including chronic inflammation and possibly neoplasia.

Intractable Biliary Candidiasis in Patients with Obstructive Jaundice and Regional Malignancy: A Retrospective Case Series.

BACKGROUND: Candida species are infrequently grown in bile cultures. An association between biliary candidiasis and regional malignancy may exist. The role of fungus membranes in frequent biliary stent occlusion is also presented in this case series. METHODS: We retrospectively identified patients who underwent percutaneous trans-hepatic cholangiogram (PTC) for obstructive jaundice between January 2014 and January 2019. The results of bile cultures - obtained by PTC - for all patients were analyzed, and patients with fungus growth were determined; their medical records were reviewed. RESULTS: A total of 71 patients with obstructive jaundice underwent PTC between January 2015 and January 2019. Five patients (all male; mean age 55.8 years) had candida species growth in bile cultures. Two patients were diagnosed with cholangiocarcinoma, one with adenocarcinoma of the head of the pancreas, one with gallbladder cancer, and one with locally advanced gastric adenocarcinoma. Formation of fungal balls predisposed to frequent PTC drain clogging. Eradication of Candida was achieved in 4 patients after 10 days to 3 weeks of antifungal therapy. CONCLUSION: We present a case series of biliary candidiasis in patients with obstructive jaundice and regional malignancy. We suggest that patients with obstructive jaundice and regional malignancy should be screened for biliary candidiasis. Persistent cholestasis may be caused by the recurrent formation of fungal membranes (balls).

Completely resolved advanced biliary tract cancer after treatment by pembrolizumab: a report of two cases.

Biliary tract cancers (BTC) represent an aggressive disease with a dismal prognosis. Gemcitabine in combination with cisplatin is the standard first-line palliative treatment for advanced BTC. There is no established treatment following progression on gemcitabine-cisplatin. In this article, we present two cases for individuals with advanced BTC who were treated with pembrolizumab and the tumors have completely resolved.

Portomesenteric Venous Thrombosis Post-Laparoscopic Sleeve Gastrectomy: Do Energy Systems Pose as Instigating Factor to This Infrequent Complication?

BACKGROUND: Portomesenteric venous thrombosis (PMVT), a rare complication after laparoscopic sleeve gastrectomy (LSG). Severe consequences are owed to a high risk of bowel ischemia. Our aim is to present a series of patients who developed PMVT after LSG, highlighting the potential role of the vessel sealer and divider as a risk factor. METHODS: Medical records of seven patients who underwent LSG and developed PMVT from April 2010 to January 2019, at King Abdullah University Hospital and Jordan University Hospital, Jordan were reviewed. Our findings were studied, audited, and compared with published data. RESULTS: A sum of 4900 patients underwent LSG, 7 (0.14%) developed PMVT. The mean age and body mass index (BMI) were 36.8 years and 45 kg/m2, respectively. Four were women. Epigastric pain radiating to the back was the presenting symptom at a median time of 9 days after surgery. Computed tomography (CT) of the abdomen confirmed the diagnosis. Five patients presented with a total portal vein thrombosis (PVT), one with splenic vein thrombosis and one with dual portal and mesenteric vein thrombosis. CONCLUSION: Portomesenteric venous thrombosis is a relatively uncommon complication following LSG. Early recognition is required to avoid catastrophic outcomes. The role of energy systems in the development of PMVT remains unknown and requires further elaboration.

Massive Rhabdomyolysis; A Rare Cause of Hepatocellular Dysfunction.

BACKGROUND Rhabdomyolysis syndrome is a rare surgical complication. It is infrequently reported in prolonged operations under lateral decubitus position. This syndrome mainly impacts kidney function and electrolytes levels; liver is another organ that is uncommonly affected. CASE REPORT A 54-year-old male underwent a partial hepatectomy in the supine position, the procedure lasted three hours. After five days of uneventful recovery from surgery, he was readmitted to the hospital with rhabdomyolysis syndrome involving his lower limbs. No predisposing factors other than surgery could be identified. Based on blood tests, the only affected organ was the liver. Upon aggressive hydration, the creatinine kinase, hepatic enzymes, bilirubin levels, and prothrombin time were normalized. The patient regained normal physical strength over the next few weeks. CONCLUSIONS Liver dysfunction secondary to rhabdomyolysis is rare but should be considered when other causes are excluded. Prothrombin time, bilirubin levels and albumin levels may help to identify concomitant liver damage. Rhabdomyolysis is rarely reported in liver resection surgeries.

Granulomatous Mastitis: A Rare Cause of Male Breast Lump.

BACKGROUND: Mastitis is a common benign disorder of the female breast. It is frequently associated with tenderness, swelling and nipple discharge. We are describing an extremely rare case of an idiopathic granulomatous mastitis in the male breast. Only 1 previous case was reported. CASE REPORT: A 29-year-old male patient presented with a hard, painless lump in the right breast of 2 weeks duration. The patient underwent surgical excision with margin. The histopathologic findings were consistent with granulomatous mastitis. The case was reported as idiopathic granulomatous mastitis after exclusion of all known causes of the disease. CONCLUSION: Granulomatous mastitis is rare in females and extremely rare in male breast tissue. Since this disease mimics breast cancer in its clinical picture and radiologic findings are usually not conclusive, surgical excision is recommended in all cases.

Parasitic leiomyoma. A rare cause of inguinal mass in females.

Leiomyoma of the uterus is a common tumor during the reproductive age of females. It is classified as intrauterine and extrauterine. Extrauterine leiomyomas may occur without a concurrent uterine pathology. Different growth patterns have been described, like retroperitoneal and parasitic growth. We report a case of a 28-year-old female who was found to have inguinal mass, and it was finally diagnosed as parasitic leiomyoma. The mass was coming through the posterior inguinal wall into the subcutaneous region, like a direct inguinal hernia. She underwent excision of the mass, and repair of posterior inguinal wall. Parasitic leiomyoma can be a rare cause of inguinal swelling. When diagnosed, surgical excision is the treatment of choice.

Laparoscopic splenectomy: consensus and debatable points.

INTRODUCTION: The emergence of minimally invasive techniques has broadened interest in splenectomy for a variety of haematological illnesses. Laparoscopic splenectomy (LS) is currently considered the gold standard for the treatment of various haematological disorders. PURPOSE: The literature was reviewed to highlight points of consensus and debatable points regarding best practice in LS, looking at issues such as bleeding and conversion, splenomegaly, splenic retrieval techniques, types of instruments used, hand-assisted LS (HALS), complications, approaches, accessory spleen and splenosis. Our goal was to share our experience with LS and compare it with other reports. BACKGROUND: LS has emerged as the standard of care for elective splenectomy for benign haematological diseases. However, doubts have been raised regarding the suitability of patients with splenomegaly for LS. There is also uncertainty about its efficacy in major trauma. HALS has emerged as an option for safe manipulation and splenic dissection. METHOD: We performed 25 consecutive LSs at King Abdullah University Hospital (KAUH), Jordan, from 2001 to 2008. Patient demographics, operative time, intra- and postoperative complications, conversion rate, additional procedures and length of hospital stay were retrospectively reviewed. RESULTS: The mean age of the patients was 38.8 years (range 11-77 years), mean operative time was 132 minutes (90- 170 minutes), and length of hospital stay was 2.9 (standard deviation 2.7) days. One case was converted to open surgery (5%). There was 1 case of superficial wound infection in the series (5%), and no deaths. CONCLUSION: LS is a well- accepted minimally invasive procedure, but knowledge and skill are required to perform it with minimal morbidity and mortality.

Spontaneous regression in alveolar soft part sarcoma: case report and literature review.

BACKGROUND: Sarcomas are a type of malignant tumors that arise from connective tissue. They are most of the time found in extremities CASE PRESENTATION: We are presenting a case of adult male patient, who was found to have huge abdominal mass and multiple gastric and duodenal polyps. Pathological diagnosis for all lesions was Alveolar soft part sarcoma. Although he complained from metastasis to both lungs and right atrium, all these deposits regressed spontaneously. Patient stated that he used some herbs (Teucrium polium, Cat Thyme) prescribed for him. No chemotherapy or radiotherapy was given. The duration of regression was about 5 months before other lesions appeared. Later on, he died secondary to brain metastasis. CONCLUSION: ASPS is a rare type of sarcomas that affect primarily the lower limbs. This tumor does rarely metastasize to the gastrointestinal tract.

Jejunal disorders: potentially lethal causes of acute abdomen are still overlooked.

OBJECTIVE: To highlight the importance of considering jejunal disorders in the differential diagnosis of acute abdomen. Although these conditions are relatively uncommon, we should keep in mind that jejunum still occurs, and deserves consideration. METHOD: This study was carried out at King Abdullah University Hospital, Jordan. Medical records of 7 patients with uncommon jejunal disorders that were encountered between 2001 and 2007 were retrospectively evaluated. We had 1 patient with jejunal diverticulitis, 1 with jejunal intussusception, 2 with jejuno-ileal tuberculosis complicated by intestinal obstruction, and 3 with acute mesenteric ischemia. All of these patients presented with acute abdominal pain of nonspecific features. Radiologic workup, along with surgical intervention, was necessary to reach a final diagnosis. RESULTS: Only 1 patient matched preoperative diagnosis, in which computed tomography scan revealed the presence of intussusception. The remaining patients were diagnosed intraoperatively. Laparoscopy and/or laparotomy with resection were performed. Morbidity was within acceptable range. There was no mortality. CONCLUSIONS: Jejunal disorders are potentially serious, and are underestimated. They are considered important causes of acute abdomen. Although they should not be at the top of a differential diagnostic list, they should always be ruled out when there is no apparent cause.

Safety of endoscopic retrograde cholangiopancreatography during pregnancy.

BACKGROUND: The risk of choledocholithiasis is expected to be higher during pregnancy. This is attributed to alteration in bile composition as well as biliary stasis that take place during gestation. There is significant concern regarding application of endoscopic procedures especially the more invasive ones for treatment of choledocholithiasis during pregnancy. Our aim was to provide an additional support to the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) in the management of biliary diseases during pregnancy. METHODS: The medical records of 10 pregnant patients who underwent ERCP at King Abdullah University Hospital, during the period from 2002 to 2007 were reviewed. Pregnancy course and outcomes were followed up in all cases. Results were analysed and compared with published data on safety and efficacy of this procedure. RESULTS: The mean age for mothers was 24.3 years. The mean duration of gestation was 18.4 weeks. Two patients were in the first trimester, five were in their second trimester and another three in the third trimester. The main indication for ERCP was obstructive choledocholithiasis on ultrasound and liver function tests. Fetal radiation exposure was not routinely measured. During, or after, the procedure there was no need for tocolytic agents. Also there was no intrauterine fetal distress. Screening for congenital anomalies was negative in all cases. CONCLUSION: Major complications of biliary obstruction have been prevented through this procedure. Short-term follow up for all neonates whom mothers underwent ERCP during pregnancy supports its safety. However, specific long-term fetal complications of radiation exposure have not been investigated yet.
