    Abstract Background: In recent years, there has been a marked growth in the use of ionizing radiation in medical imaging for both diagnosis and therapy, which in turn has led to increased radiation exposure among healthcare workers.
    Aim: The purpose of this study was to assess the level of safety compliance awareness among healthcare workers exposed to ionizing radiation.
    Research design: A descriptive cross-sectional design was used for this investigation.
    Setting: This study was conducted online, using social media sites such as WhatsApp, Instagram, and Facebook.
    Subjects: A purposive sample of 384 Egyptian healthcare workers was enrolled in the current study. TOOL: A safety compliance awareness questionnaire was used in this study to collect pertinent data.
    Results: The result of this study showed that 65.4% and 64.1% of the studied sample chose the correct answers that mammography and CT scans involve the use of x-rays. However, 64.3% and 67.2% of the studied sample chose the wrong answers, saying that MRI and Ultrasound involve the use of X-rays. Moreover, 47.14%, 43.5%, and 57% of the studied sample never used a dosimeter, did not follow dosimeter controls, and did not wear a lead collar.
    Conclusion: Most of the healthcare workers studied had poor knowledge about radiation exposure safety. Moreover, most of the healthcare workers in the current study demonstrated inadequate practice compliance concerning radiation protection procedures.
    Recommendation: Should encourage hospital training programs to include radiation safety topics in their training plans for healthcare workers.

    Abstract Objective: Hypotension is the most frequent side effect of intrathecal anaesthesia, with an incidence of more than 80%. Following neuraxial anaesthesia, perioperative shivering is a serious complication affecting 40-60% of patients undergoing surgery. This study aimed to determine the effectiveness of low-dose ketamine on blood pressure in patients undergoing cesarean delivery after spinal anaesthesia.
    Methods: We included 126 female patients undergoing cesarean deliveries, American Society of Anesthesiologists (ASA)-(II and III), and aged 21-40 selected from the outpatient clinics of the anaesthesia department. Patients were randomized to two groups; Group K (63 patients), who received 0.3 mg kg
    Results: Compared with the saline group, the average heart rate, blood pressure, and level of sedation were significantly higher in the ketamine group (
    Conclusion: Ketamine decreases the incidence of hypotension and shivering in patients undergoing spinal anaesthesia during cesarean delivery. In addition, it resulted in improved sedation for the mother and prolonged postoperative analgesia without neonatal illness.

    Abstract Background: Haemangiomas are the most common benign liver tumors. Treatment is indicated for symptomatic tumors, rapid increase in size, rupture or doubt in diagnosis. Objective: Evaluation the efficacy of surgical treatment of giant cavernous hepatic haemangioma in tertiary hepatobiliary center. Patients and Methods: Retrospective study of 34 patients with giant hepatic haemangioma operated upon. The diagnosis was proved preoperatively in 27 patients and confirmed by histopathology postoperatively in all patients. The indication of surgery was abdominal pain with large sizes tumors, rapid growth, and spontaneous rupture with haemoperitoneum. Surgical treatment either liver resection or living liver transplantation. Results: 23 cases (67.6%) were females & 11 cases (32.4%) were males, median age 38.8 years. Haemangiomas located in right lobe in 19 patients (55.9%), left lobe in 12 patients (35.4%) in both lobe in 2 patients (5.8%), scattered all over both lobe in one patient (2.9%), solitary in 27 cases (79.4%) and multiple in 7 patients (20.6%). The diameter was 8 - 27 cm, mean 18.6 cm in diameter. 33 patients had liver resection (29 elective resection and 4 emergent resection for rupture). One patient had haemangioma irresectable; the living liver transplant was performed. No mortality during 18 months follow up and complication occurred in 8 patients out of 34 patients. Conclusion: Hepatic resection is an effective treatment option for giant cavernous hepatic haemangioma, in selected patient living related liver transplantation may be the only therapeutic option.

    Abstract Introduction: Situs inversus totalis is a rare anomaly characterized by transposition of organs to the opposite site of the body. Laparoscopic cholecystectomy in those patients is technically more demanding and needs reorientation of visual-motor skills to left upper quadrant.
    Presentation of case: Herein, we report a 10 year old boy presented with left hypochondrium and epigastric pain 2 months duration. The patient had not been diagnosed as situs inversus totalis before. The patient exhibit a left sided "Murphy's sign". Diagnosis of situs inversus totalis was confirmed with ultrasound, computerized tomography (CT) and magnetic resonant image (MRI) with presence of multiple gall bladder stones with no intra or extrabiliary duct dilatation. The patient underwent laparoscopic cholecystectomy for cholelithiasis.
    Discussion: Feasibility and technical difficulty in diagnosis and treatment of such case pose challenge problem due to the contra lateral disposition of the viscera. Difficulty is encountered in skelatonizing the structures in Calot's triangle, which consume extra time than normally located gall bladder. A summary of additional 50 similar cases reported up to date in the medical literature is also presented.
    Conclusion: Laparoscopic cholecystectomy is feasible and should be done in situs inversus totalis by experienced laparoscopic surgeon, as changes in anatomical disposition of organ not only influence the localization of symptoms and signs arising from a diseased organ but also imposes special demands on the diagnosis and surgical skills of the surgeon.

    Abstract Background: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal neoplasms of the digestive system. They originate from the interstitial cells of Cajal and are characterized by the over expression of KIT protein (Tyrosine Kinase), and they pose a diagnostic and therapeutic dilemma. Objective: A challenge in diagnosis and treatment of GIST Patients & Methods: This is a retrospective study of GIST cases that diagnosed and treated in our center during the past 5 years. These studies include clinical characteristics, imaging techniques, neoadjuvant therapy, surgical techniques, immunohistochemistry, and prognosis of such cases. Results: Sixteen patients were diagnosed as having GIST (12 males/4 females) with a mean age 62 years (31-83 years). Diagnosis was made preoperatively in 11 patients (69%) and intraoperatively with histopatholgical confirmation in five patients (31%). The site of the tumor was detected in the stomach in 6 cases (37.5%), one in duodenum (6.25%), five in small intestine (31.25%), one in mesentery (6.25%), two in colon (12.5%) and one rectal GIST (6.25%). The main presentation of the disease was anemia, GIT bleeding and abdominal mass. Fourteen patients considered resectable and they were operated upon (87.5%) and in two patients (12.5%) neadjuvant therapy was started with favorable response in one case and poor response in other one with advanced GIST. All patients received Imatinib as adjuvant therapy. Mean follow up period was 33 months (4-54 months). Conclusion: GIST is a complex and challenging disease that requires a multidisciplinary approach in specililized center for better prognosis of such disease.

    Abstract Background: Advances in computer enhancements for surgery, including a voice-activated control system for minimally invasive surgery, are being introduced into clinical practice. Few reports have objectively evaluated the utility of the voice-activated control system. The aim of this study was to evaluate the utility of a voice-activated control system for delivery of commands to specific operating room (OR) equipment.
    Materials and methods: We evaluated a total of 30 laparoscopic procedures: 15 laparoscopic hernia repairs, 10 laparoscopic cholecystectomies, and 5 laparoscopic fundoplications performed with the HERMEStrade mark Operating Room Control Center (Computer Motion, Santa Barbara, California) voice-activated control system. When the voice command (VC) to the HERMES system was given, the circulating nurse was observed and her location was recorded. The 3 locations were A, the nurse was immediately available in the OR, not engaged in any other tasks; B, the nurse was in the OR but engaged in other tasks; or C, the nurse was outside the OR.
    Results: The 30 cases were performed by the same surgeon and completed laparoscopically. For 170 VCs for gas insufflation, the location of the circulating nurse was: A=50, B=98, and C=22. For 135 light source adjustments, the locations were A=34, B=82, and C=19. In 76 white balance VCs: A=16, B=51, and C=9. In 128 VCs for camera adjustment: A=27, B=77, and C=24. Eight video capture VCs: A=1, B=3, and C=4. For 69 image capture VCs: A=5, B=41, and C=23. The total number of VCs was 586: A=133 (22.7%), B=352 (60%), and C=101(17.3%). All VCs were accurately interpreted by the HERMES system.
    Conclusion: Voice-activated control systems improve communication with and efficiency of OR staff. The surgeon is afforded the most timely equipment adjustment possible. Circulating nurses are allowed to concentrate on patient care instead of equipment adjustment during the course of the surgery.

    Abstract Background. Iatrogenic biliary injuries are considered as the most serious complications during cholecystectomy. Better outcomes of such injuries have been shown in cases managed in a specialized center. Objective. To evaluate biliary injuries management in major referral hepatobiliary center. Patients & Methods. Four hundred seventy-two consecutive patients with postcholecystectomy biliary injuries were managed with multidisciplinary team (hepatobiliary surgeon, gastroenterologist, and radiologist) at major Hepatobiliary Center in Egypt over 10-year period using endoscopy in 232 patients, percutaneous techniques in 42 patients, and surgery in 198 patients. Results. Endoscopy was very successful initial treatment of 232 patients (49%) with mild/moderate biliary leakage (68%) and biliary stricture (47%) with increased success by addition of percutaneous (Rendezvous technique) in 18 patients (3.8%). However, surgery was needed in 198 patients (42%) for major duct transection, ligation, major leakage, and massive stricture. Surgery was urgent in 62 patients and elective in 136 patients. Hepaticojejunostomy was done in most of cases with transanastomotic stents. There was one mortality after surgery due to biliary sepsis and postoperative stricture in 3 cases (1.5%) treated with percutaneous dilation and stenting. Conclusion. Management of biliary injuries was much better with multidisciplinary care team with initial minimal invasive technique to major surgery in major complex injury encouraging early referral to highly specialized hepatobiliary center.

    Abstract Background: Ecchinococcal disease is still a serious problem in certain parts of the world, with liver as the most affected organ. Surgery remains the mainstay of treatment of hydatidosis, but the optimal surgical procedure remains unsettled. Objective : Safety and efficacy of major hepatic resection in multiple and giant hepatic hydatidosis. Patients & Methods: 63 patients had hepatic hydatidosis associated with spleen, lung, and suprarenal hydatidosis were managed by major hepatic resection between April 2005 to April 2011. 43 (68%) males and 20 (32%) females, age range 8 - 56 years. Cysts were found in the liver only in 51 (81%) patients, liver with spleen in 5 (8%), liver, spleen with lung in 2 (3.1%), liver and lung in 4 (6.3%), liver and suprarenal in one patient (1.6%). Results: Multiple cysts were found in 38 (60%) and solitary cyst in 25 (40%) with Cysts diameter ≤5 cmin 22 (35%), 5 - 10 cm in 16 (25%), and 10 - 38 in 25 (40%). Right hepatectomy in 24 (38%), right trisectionectomy in 2 (3.2%), right hepatectomy with Segment III in 4 (6.3%), right hepatectomy with Segment I in 2 (3.2%), left hepatectomy in 12 (19%), left lateral sectionectomy in 6 (9.5%), left hepatectomy with Segment VI in 3 (4.8%), left lateral sectionectomy with right posterior sectionectomy in 2 (3.2%), right hepatectomy with splenectomy in 7 (11%) and right hepatectomy with right suprarenal in one (1.6%) patient were performed. Hospital stay was 4.2 (3 - 13 days) There was one mortality and 12 (19%) morbidities. No recurrence on follow up period (8 - 60 months) was observed. Conclusion: Radical procedure is safe and effective option for hepatic hydatidosis and should be performed when the entire lobe is diffusely involved by huge or multiple hydatidosis with little healthy liver tissue.

    Abstract Background: A major prerequisite for living related liver transplantation is to ensure both donor safety and optimal graft quality. Therefore, excluding unsuitable donor candidates should be an important priority of the transplant team.
    Purpose: To analyze the criteria for exclusion of potential living related liver donors.
    Patients and methods: From November 2000 to March 2005, 327 potential living related donors for 136 potential recipients for liver transplantation were screened and worked up at the Liver Transplant Center, King Abdul Aziz Medical City. They were evaluated in a stepwise manner, including medical, physical, laboratory, psychosocial, and imaging assessment. Data regarding potential donors were retrospectively reviewed. Reasons for rejection of disqualified donors were analyzed.
    Results: Out of the 327 potential donors, 223 (68.2%) were rejected at an early stage. A total of 104 cases (31.8%) had computed tomographic (CT) volumetry and/or magnetic resonance cholangiography (MRCP). While 44 (42.3% of those who had CT volumetry and/or MRCP) had their workup completed and proved to be suitable candidates, 24 (23%) went for surgery. Causes for donor rejection were classified as donor-related factors (inadequate volume, unsafe anatomy, abnormal liver function tests, medical/psychiatric, fatty liver, etc.; n = 191) and recipient-related factors (too ill, died, received cadaveric transplant, etc.; n = 112).
    Conclusion: In our experience, as well as in those from other centers, a small proportion of potential donors prove to be satisfactory candidates. Therefore, strict adherence to a stepwise evaluation process is of utmost importance, so unsuitable potential donors can be disqualified, as early as possible during workup.
