    Non-invasive ventilation is an accepted treatment modality in both acute exacerbations of respiratory diseases and chronic obstructive lung disease. It is commonly utilized in the intensive care units, or for postoperative respiratory support in post-anesthesia care units. This report describes intraoperative support in non-invasive ventilation to neuroaxial anesthesia for an emergency upper abdominal surgery. PMID:27591472

    Background Previous studies examined the effect of laparoscopic cholecystectomy (LC) versus open cholecystectomy (OC) on physiological variables of the respiratory system. In this study we compared changes in arterial blood gases-related parameters between LC and OC to assess their comparative influence on gas exchange. Methods We studied 28 patients, operated under identical anesthetic protocol (LC: 18 patients, OC: 10 patients). Measurements were made on the morning before surgery (BS), the second (AS2) and the eighth (AS8) postoperative day. Studied parameters, including alveolar-arterial difference in PO2 ((A-a)DO2) and oxygen content (Oct in vol%), were statistically compared. Results On AS2 a greater increase was found in ((A-a)DO2) for the OC compared to LC (4.673 ± 0.966 kPa versus 3.773 ± 1.357 kPa, respectively). Between BS and AS2, Oct in vol% decreased from 17.55 ± 1.90 to 15.69 ± 1.88 in the LC and from 16.99 ± 2.37 to 14.62 ± 2.23 in the OC, whilst a reduction (P = 0.093) between AS2 and AS8 was also found for the open method. Besides, on AS2, SaO2% decrease was greater in OC compared to LC (P = 0.096). Conclusions On AS2, the greater increase in OC-((A-a)DO2) associated with Oct in vol% and SaO2% findings also in OC group suggest that LC might be associated with lower risk for impaired tissue oxygenation.

    Background Laparoscopic cholecystectomy (LC) requires the creation of a pneumoperitoneum via insufflations of carbon dioxide; resulting in increased partial pressure of carbon dioxide (CO2) and intraperitoneal pressure which leads to the changes in pulmonary function and hemodynamic measurements. Hypercarbia leads to visceral organ ischemia including liver and venous stasis/thromboembolism or both due to impaired flow. The present study has been undertaken to see the changes in liver function tests (LFTs) after laparoscopic/open cholecystectomy (OC), the incidences of such change, their relation to age, sex, duration of surgery and to know the clinical significances of such disturbances. Aims and objectives To compare and correlate the serum level of bilirubin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) in patients who underwent LC to those who underwent OC. Materials and methods The present study was conducted in the Department of Surgery at MMIMSR, MM University, Mullana, Ambala. A total number of 200 patients diagnosed as cholelithiasis were included in the study from May 2012 to May 2014. These cases were randomly divided into two groups (A and B) consisting of 100 cases each. LC was performed in group A patients and OC was done in group B patients. Three blood samples were taken: (I) pre-operatively; (II) after 24 hours of surgery; and (III) after 72 hours of surgery for comparison of the enzyme level alterations. Results In LC patients, there were rise in the levels of serum bilirubin, AST and ALT after 24 hrs of surgery from the preoperative value and then again fall was noted (near to normal value) after 72 hrs of surgery except in that of ALP. ALP levels showed slight fall after 24 hrs of surgery and then slight rise after 72 hrs which was within the normal limit. Whereas in OC patients, there were slight variations in the liver enzymes (which were within the normal range). Conclusions Transient elevation of serum

    AIM: To investigate the comparative effect of laparoscopic and open cholecystectomy in elderly patients. METHODS: Laparoscopic cholecystectomy has induced a revolution in the treatment of gallbladder disease. Nevertheless, surgeons have been reluctant to implement the concepts of minimally invasive surgery in older patients. A systematic review of Medline was embarked on, up to June 2013. Studies which provided outcome data on patients aged 65 years or older, subjected to laparoscopic or open cholecystectomy were considered. Mortality, morbidity, cardiac and pulmonary complications were the outcome measures of treatment effect. The methodological quality of selected studies was appraised using valid assessment tools. Τhe random-effects model was applied to synthesize outcome data. RESULTS: Out of a total of 337 records, thirteen articles (2 randomized and 11 observational studies) reporting on the outcome of 101559 patients (48195 in the laparoscopic and 53364 in the open treatment group, respectively) were identified. Odds ratios (OR) were constantly in favor of laparoscopic surgery, in terms of mortality (1.0% vs 4.4%, OR = 0.24, 95%CI: 0.17-0.35, P < 0.00001), morbidity (11.5% vs 21.3%, OR = 0.44, 95%CI: 0.33-0.59, P < 0.00001), cardiac (0.6% vs 1.2%, OR = 0.55, 95%CI: 0.38-0.80, P = 0.002) and respiratory complications (2.8% vs 5.0%, OR = 0.55, 95%CI: 0.51-0.60, P < 0.00001). Critical analysis of solid study data, demonstrated a trend towards improved outcomes for the laparoscopic concept, when adjusted for age and co-morbid diseases. CONCLUSION: Further high-quality evidence is necessary to draw definite conclusions, although best-available evidence supports the selective use of laparoscopy in this patient population.

    A controlled, prospective, double-blind trial of wound infiltration with bupivacaine in elective open cholecystectomy was performed to determine if this was an effective method of pain relief and reduced respiratory complications. Additionally, dextran was added to the bupivacaine in an attempt to prolong the effect. The solutions used were, bupivacaine alone 0.25% (n = 14), bupivacaine 0.25% with dextran 70 (n = 16) and saline (n = 16) as a control. To determine the effect of each solution, the subjects were assessed for pain perception and respiratory function before and after surgery. Pain was assessed using a visual analogue scale and narcotic usage, and respiratory function was assessed by spirometry, chest X-rays and arterial blood gases. The study did not demonstrate any objective improvement in either pain relief or respiratory function. This may reflect inadequate infiltration by the surgeons in the study or that infiltration should have been performed prior to incision. PMID:7506020

    Perforin-(P-) related characteristics of cytotoxic T lymphocytes and natural killer cells were investigated in peripheral blood of patients subjected to open (OC; n = 23) or laparoscopic cholecystectomy (LC; n = 21) and healthy controls (n = 20). Blood samples were obtained preoperatively and 24 hours after the surgeries, and the data were correlated with the intensity of cholestasis and concomitant inflammation, determined by functional hepatic tests. Postoperative differences were found to be minimal: OC decreased only the percentage of CD56+ cells, while LC decreased the fraction of CD8+P+ cells and augmented the mean fluorescence intensity of P in CD56 cells. Patients elected for OC had, however, higher preoperative numbers of total P+, CD3+P+, and CD4+P+ cells than patients elected for LC and healthy controls, while both groups of patients, preoperatively, had lower fraction of CD16+P+ and CD56+P+ cells. These changes were in high correlation with blood concentrations of CRP, AP, and ALT, emphasizing the link between the preoperative cholestasis and inflammation and P-dependent cytotoxic mechanisms.

    Twelve children underwent elective laparoscopic cholecystectomy for symptomatic cholelithiasis during a 10-month period in one institution. The operative technique that has been described for adults was modified because of the smaller dimensions of pediatric patients. These modifications are discussed in this report, as are new alternatives for evaluating the common duct. No operative complications or conversions to open cholecystectomy occurred, and no complications after surgery were seen during an average follow-up period of 4.5 months. The benefits of laparoscopic cholecystectomy include decreased pain and ileus after surgery, shortened hospitalization, and improved cosmesis. Laparoscopic cholecystectomy is safe and efficacious in children, and it compares favorably with traditional cholecystectomy in the pediatric age group. Images FIG. 3. PMID:1532120

    We report a case of a 76-year-old man, receiving dual antiplatelet therapy (DAPT) with aspirin and ticlopidine for the past 6 years after implantation of drug-eluting coronary stent, developed a severe hypochondriac pain. After diagnosing severe acute cholecystitis by an enhanced CT, emergent laparotomy under continuation of DAPT was attempted. During the operation, intractable bleeding from the adhesiolysed liver surface was encountered, which required platelet transfusion. Subtotal cholecystectomy with abdominal drainage was performed, and the patient recovered without any postoperative bleeding or thromboembolic complications. Like the present case, the final decision should be made to perform platelet transfusion when life-threatening DAPT-induced intraoperative bleeding occurs during an emergent surgery, despite the elevated risk of stent thrombosis.

    The mission of the OASIS (Organization for the Advancement of Structured Information Standards) Emergency Management Technical Committee (EM-TC) is to create incident and emergency-related standards for data interoperability. The TC welcomes participation from members of the emergency management community, developers and implementers, and members of the public concerned with disaster management and response. Since the foundation of the EM-TC in 2003, there have been several Standards developed to support this mission. The first and most widely accepted has been the Common Alerting Protocol (CAP). CAP has been adopted worldwide and is also ITU Recommendation 1303. The EM-TC has continued in the development of content data standards to support the emergency management mission. This suite of standards is referred to as the Emergency Data Exchange Language (EDXL) family of standards. The EDXL suite of standards are developed starting with a defined requirement from the response community. The requirements are vetted through a working group process, reviewed by the development community to determine whether the concepts once "standardized" will result in software that will be developed then provided with comments to the OASIS EM-TC for defining the standard. The OASIS process includes an open public review period where all comments are accepted and publically adjudicated. The EDXL-Distribution Element (DE), EDXL-Resource Management (RM), EDXL-Hospital Availability eXchange (HAVE) are all now ratified Standards. The EDXL-Situation Reporting (SitRep) Standard is in final review and the EXDL-Tracking of Emergency Patients (TEP) is in development. This presentation will briefly present each of the OASIS EM-TC Standards as well as the process for their development and review. Information will be provided about how to participate in the process as well as where open source code can be found to get started developing systems of systems using the EDXL Standards.

    Objectives Biliary injuries are frequently accompanied by vascular injuries, which may worsen the bile duct injury and cause liver ischemia. We performed an analytical review with the aim of defining vasculobiliary injury and setting out the important issues in this area. Methods A literature search of relevant terms was peformed using OvidSP. Bibliographies of papers were also searched to obtain older literature. Results Vasculobiliary injury was defined as: an injury to both a bile duct and a hepatic artery and/or portal vein; the bile duct injury may be caused by operative trauma, be ischaemic in origin or both, and may or may not be accompanied by various degrees of hepatic ischaemia. Right hepatic artery (RHA) vasculobiliary injury (VBI) is the most common variant. Injury to the RHA likely extends the biliary injury to a higher level than the gross observed mechanical injury. VBI results in slow hepatic infarction in about 10% of patients. Repair of the artery is rarely possible and the overall benefit unclear. Injuries involving the portal vein or common or proper hepatic arteries are much less common, but have more serious effects including rapid infarction of the liver. Conclusions Routine arteriography is recommended in patients with a biliary injury if early repair is contemplated. Consideration should be given to delaying repair of a biliary injury in patients with occlusion of the RHA. Patients with injuries to the portal vein or proper or common hepatic should be emergently referred to tertiary care centers. PMID:21159098

    Prof Dr Med Erich Mühe of Böblingen, Germany, performed the first laparoscopic cholecystectomy on September 12, 1985. The German Surgical Society rejected Mühe in 1986 after he reported that he had performed the first laparoscopic cholecystectomy, yet in 1992 he received their highest award, the German Surgical Society Anniversary Award. In 1990 in Atlanta, at the Society of American Gastrointestinal Surgeons (SAGES) Convention, Perissat, Berci, Cuschieri, Dubois, and Mouret were recognized by SAGES for performing early laparoscopic cholecystectomies, but Mühe was not. However, in 1999 he was recognized by SAGES for having performed the first laparoscopic cholecystectomy-SAGES invited Mühe to present the Storz Lecture. In Mühe's presentation, titled "The First Laparoscopic Cholecystectomy," which he gave in March 1999 in San Antonio, Texas, he described the first procedure. Finally, Mühe had received the worldwide acclaim that he deserved for his pioneering work. One purpose of this article is to trace the development of the basic instruments used in laparoscopic cholecystectomy. The other purpose is to give Mühe the recognition he deserves for being the developer of the laparoscopic cholecystectomy procedure. PMID:11304004

    Introduction Laparoscopic cholecystectomy (LC) is the gold standard treatment for symptomatic cholelithiasis. However, of all Laparoscopic cholecystectomies, 1-13% requires conversion to an open for various reasons. Thus, for surgeons it would be helpful to establish criteria that would predict difficult laparoscopic cholecystectomy and conversion preoperatively. But there is no clear consensus among the laparoscopic surgeons regarding the parameters predicting the difficult dissection and conversion to open cholecystectomy. Aim To assess the clinical and radiological parameters for predicting the difficult laparoscopic cholecystectomy and its conversion. Materials and Methods This was a prospective study conducted from October 2010 to October 2014. Total of 180 patients meeting the inclusion criteria undergoing LC were included in the study. Four parameters were assessed to predict the difficult LC. These parameters were: 1) Gallbladder wall thickness; 2) Pericholecystic fluid collection; 3) Number of attacks; 4) Total leucocyte count. The statistical analysis was done using Z-test. Results Out of 180 patients included in this study 126 (70%) were easy, 44 (24.44%) were difficult and 3 (5.56%) patients required conversion to open cholecystectomy. The overall conversion rate was 5.6%. The TLC>11000, more than 2 previous attacks of cholecystitis, GB wall thickness of >3mm and Pericholecystic collection were all statistically significant for predicting the difficult LC and its conversion. Conclusion The difficult laparoscopic cholecystectomy and conversion to open surgery can be predicted preoperatively based on number of previous attacks of cholecystitis, WBC count, Gall bladder wall thickness and Pericholecystic collection.

    Background. The aim of this population-based study was to describe characteristics of patients with liver cirrhosis undergoing cholecystectomy and evaluate the risk for perioperative and postoperative complications during the 30-day postoperative period. Method. All laparoscopic and open cholecystectomy procedures registered between 2006 and 2011 in the Swedish Registry for Gallstone Surgery and ERCP (GallRiks) were included. Patients with liver cirrhosis were identified by linking data to the Swedish National Patient Registry (NPR). Results. Of 62,488 patients undergoing cholecystectomy, 77 (0.12%) had cirrhosis, of which 29 patients (37.7%) had decompensated cirrhosis. Patients with cirrhosis were older and had more often gallstone complications at the time for surgery. Postoperative complications were registered in 13 (16.9%) patients with liver cirrhosis and in 5,738 (9.2%) patients in the noncirrhotic group (P < 0.05). Univariable analysis showed that patients with liver cirrhosis are more likely to receive postoperative blood transfusion (OR = 4.4, CI 1.08–18.0, P < 0.05) and antibiotic treatment >1 day (OR = 2.3, CI 1.11–4.84, P < 0.05) than noncirrhotic patients. Conclusion. Patients with cirrhosis undergoing cholecystectomy have a higher incidence of postoperative complications than patients without cirrhosis. However, cholecystectomy is safe and if presented with adequate indication, surgery should not be delayed due to fears of surgical complications. PMID:26788053

    Background Epidemiological data on characteristics of patients undergoing open or laparoscopic cholecystectomy are limited. In this register study we examined characteristics and mortality of patients who underwent cholecystectomy during hospital stay in Sweden 2000 – 2003. Methods Hospital discharge and death certificate data were linked for all patients undergoing cholecystectomy in Sweden from January 1st 2000 through December 31st 2003. Mortality risk was calculated as standardised mortality ratio (SMR) i.e. observed over expected deaths considering age and gender of the background population. Results During the four years of the study 43072 patients underwent cholecystectomy for benign biliary disease, 31144 (72%) using a laparoscopic technique and 11928 patients (28%) an open procedure (including conversion from laparoscopy). Patients with open cholecystectomy were older than patients with laparoscopic cholecystectomy (59 vs 49 years, p < 0.001), they were more likely to have been admitted to hospital during the year preceding cholecystectomy, and they had more frequently been admitted acutely for cholecystectomy (57% Vs 21%, p < 0.001). The proportion of women was lower in the open cholecystectomy group compared to the laparoscopic group (57% vs 73%, p < 0.001). Hospital stay was 7.9 (8.9) days, mean (SD), for patients with open cholecystectomy and 2.6 (3.3) days for patients with laparoscopic cholecystectomy, p < 0.001. SMR within 90 days of index admission was 3.89 (3.41–4.41) (mean and 95% CI), for patients with open cholecystectomy and 0.73 (0.52–1.01) for patients with laparoscopic cholecystectomy. During this period biliary disease accounted for one third of all deaths in both groups. From 91 to 365 days after index admission, SMR for patients in the open group was 1.01 (0.87–1.16) and for patients in the laparoscopic group 0.56 (0.44–0.69). Conclusion Laparoscopic cholecystectomy is performed on patients having a lower mortality risk than

    This paper reports the experience of three general surgeons performing 304 laparoscopic cholecystectomies in three private hospitals between October 1989 and November 1990. Laparoscopic cholecystectomy boasts two major advantages over the conventional procedure: the remarkable reduction in postoperative pain and economic benefit, largely due to the patient's early return to work. Revealing a complication rate of 2% and no deaths, this study has shown that this procedure can offer patients these advantages with a medical risk no greater than that accompanying conventional cholecystectomy. Patient safety must be paramount, and it is the responsibility of the surgical community to ensure that all surgeons receive the highest quality training and that the technique is applied appropriately.

    Laparoscopic cholecystectomy has become a standard treatment of symptomatic gallstone disease. Although spilled gallstones are considered harmless, unretrieved gallstones can result in intra-abdominal abscess. We report a case of abscess formation due to spilled gallstones after laparoscopic cholecystectomy mimicking a retroperitoneal sarcoma on radiologic imaging. A 59-year-old male with a surgical history of a laparoscopic cholecystectomy complicated by gallstones spillage presented with a 1 mo history of constant right-sided abdominal pain and tenderness. Computed tomography and magnetic resonance imaging demonstrated a retroperitoneal sarcoma at the sub-hepatic space. On open exploration a 5 cm × 5 cm retroperitoneal mass was excised. The mass contained purulent material and gallstones. Final pathology revealed abscess formation and foreign body granuloma. Vigilance concerning the possibility of lost gallstones during laparoscopic cholecystectomy is important. If possible, every spilled gallstone during surgery should be retrieved to prevent this rare complication. PMID:27158213

    Explosively actuated openings in composite panels are proposed to enhance passenger survivability within commercial aircraft by providing improvements in emergency openings, fuselage venting, and fuel dump. The concept is to embed a tiny, highly stable explosive cord in the periphery of a load-carrying composite panel; on initiation of the cord, the panel is fractured to create a well-defined opening. The panel would be installed in the sides of the fuselage for passenger egress, in the top of the fuselage for smoke venting, and in the bottoms of the fuel cells for fuel dump. Described are the concerns with the use of explosive systems, safety improvements, advantages, experimental results, and recommended approach to gain acceptance and develop this concept.

    Background Intrahepatic gallbladder perforation with chronic liver abscess formation was anecdotically reported in the literature. The aim of this work is to report a case of intrahepatic gallbladder perforation and its atypical clinical presentation. Case presentation A 62-year-old male patient came to our observation; his medical history showed intermittent fever up to 39-40°C of about 2 weeks and anorexia, with an overall weight loss of about 12 Kg. Physical examination of the abdomen was negative. An ultrasound of the liver and an abdominal CT angiogram detected a disomogeneous hypoechoic-hypodense area in the 5th segment of the liver. Differential diagnosis between hepatic abscess or gallbladder cancer remained open. A surgical exploration was planned. After laparoscopic exploration, a conversion to open procedure with an atypical resection of the 5th hepatic segment was performed. Histologic examination of the specimen showed an intrahepatic chronic perforation of the gallbladder with intrahepatic abscess. Conclusion To the best of our knowledge, 18 cases have been reported in the literature as a Niemeier type I perforation. Clinical presentation, even in its extreme rarity, is more often acute. Differential diagnosis between gallbladder cancer versus liver abscess remains controversial. Open approach is mandatory in such cases. PMID:24468118

    This study was conducted on 100 patients with symptomatic gallbladder stones, aged 22-81 years with a mean of 51.5 years, who underwent cholecystectomy in Zarqa city, Jordan between July 1998 and July 1999. The success rate was 87% and the procedure was completed using the conventional method in 13 patients. The mean operative time was 60 minutes, complication rate was 5% and there were no deaths. The mean hospital stay was 1 day and mean time to return to work was 10 days. This study showed that laparoscopic cholecystectomy is a safe procedure with reasonable operative time, less postoperative pain, a short hospital stay, early return to work, and a low morbidity and mortality rate.

    The possibility of conversion to open cholecystectomy (OC) always exists while performing a laparoscopic cholecystectomy (LC). This study has been performed with the aim of identifying factors predicting conversion to OC. From October 1992-April 1994, LC was attempted in 150 patients and conversion to OC was required in 29 (19%) patients. Ten preoperative factors were analyzed retrospectively to identify parameters significantly correlating with conversion to OC. Preoperative factors analyzed were age, sex, duration of symptoms, BMI (Body Mass Index), past history of jaundice, previous abdominal surgery, associated medical risk factors, palpable lump on clinical examination, USG, and OCG findings. Univariate and multiple stepwise regression analysis identified male sex, USG finding of contracted/thick-walled gall bladder, and a palpable gall bladder lump on examination as significant preoperative factors predicting conversion to OC.

    Today, laparoscopic cholecystectomy is the method of choice for treatment of symptomatic gallbladder disorders. It minimizes effects of the operation that are independent of the gallbladder, such as trauma to the abdominal wall and other soft tissue. The surgical wounds were even smaller when 2-mm trocars were used. Laparoscopic cholecystectomy using 2-mm instruments was performed in a consecutive series of 14 patients with symptomatic gallstones. The procedure was completed in 12 cases, with conversion to open surgery in two cases. Intraoperative cholangiography was always performed. The postoperative course was always uneventful. The cosmetic effect was highly satisfactory. The procedure using 2-mm instruments could be indicated in selected patients with uncomplicated gallstone disease. PMID:9820716

    BACKGROUND: Incomplete gallbladder removal following open and laparoscopic techniques leads to residual gallbladder stones. The commonest presentation is abdominal pain, dyspepsia and jaundice. We reviewed the literature to report diagnostic modalities, management options and outcomes in patients with residual gallbladder stones after cholecystectomy. MATERIALS AND METHODS: Medline, Google and Cochrane library between 1993 and 2013 were reviewed using search terms residual gallstones, post-cholecystectomy syndrome, retained gallbladder stones, gallbladder remnant, cystic duct remnant and subtotal cholecystectomy. Bibliographical references from selected articles were also analyzed. The parameters that were assessed include demographics, time of detection, clinical presentation, mode of diagnosis, nature of intervention, site of stone, surgical findings, procedure performed, complete stone clearance, sequelae and follow-up. RESULTS: Out of 83 articles that were retrieved between 1993 and 2013, 22 met the inclusion criteria. In most series, primary diagnosis was established by ultrasound/computed tomography scan. Localization of calculi and delineation of biliary tract was performed using magnetic resonance imaging/magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography. In few series, diagnosis was established by endoscopic ultrasound, intraoperative cholangiogram and percutaneous transhepatic cholangiography. Laparoscopic surgery, endoscopic techniques and open surgery were the most common treatment modalities. The most common sites of residual gallstones were gallbladder remnant, cystic duct remnant and common bile duct. CONCLUSION: Residual gallbladder stones following incomplete gallbladder removal is an important sequelae after cholecystectomy. Completion cholecystectomy (open or laparoscopic) is the most common treatment modality reported in the literature for the management of residual gallbladder stones. PMID:26622110

    Introduction Differentiation between patients with acute cholecystitis and patients with severe biliary colic can be challenging. Patients with undiagnosed acute cholecystitis can incur repeat emergency department (ED) visits, which is resource intensive. Methods Billing records from 2000 – 2013 of all adults who visited the ED in the 30 days preceding their cholecystectomy were analyzed. Patients who were discharged from the ED and underwent elective cholecystectomy were compared to those who were discharged and returned to the ED within 30 days. T-tests, chi-square tests and multivariable analysis were utilized as appropriate. Results From 2000 - 2013, 3138 patients (34%) presented to the ED within 30 days prior to surgery, 63% were women, mean age 51 years, and of those 1625 were directly admitted from the ED for cholecystectomy while 1513 patients left the ED to return for an elective cholecystectomy. Patients who were discharged were younger (mean age 49 vs 54 yrs, p<0.001) and had shorter ED stays (5.9 vs 7.2 hrs, p<0.001) than the patients admitted immediately. Of the discharged patients, 303 (20%) returned to the ED within 30 days to undergo urgent cholecystectomy. Compared to patients with successful elective cholecystectomy after the ED visit, those who failed the pathway were more likely to have an ASA score > 3 and were <40 or ≥60 compared to the successful group. Conclusions One in five patients failed the elective cholecystectomy pathway after ED discharge, leading to additional patient distress and use of resources. Further risk factor assessment may help design efficient care pathways. PMID:25043530

    Cholecystectomy is a common procedure. Abnormalities in the anatomy of the biliary system are common but an abnormal location of the gallbladder is much rarer. Despite frequent pre-operative imaging, the aberrant location of the gallbladder is commonly discovered at surgery. This article presents a case of a patient with the gallbladder located to the left of the falciform ligament in the absence of situs inversus totalis that presented with right upper quadrant pain. A laparoscopic cholecystectomy was performed and it was noted that the cystic duct originated from the right side. The presence of a left sided gall bladder is often associated with various biliary, portal venous and other anomalies that might lead to intra-operative injuries. The spectrum of unusual positions and anatomical gallbladder abnormalities is reviewed in order to facilitate elective and emergent cholecystectomy as well as other hepatobiliary procedures. With proper identification of the anatomy, minimally invasive approaches are still considered safe. PMID:24124340

    Laparoscopic cholecystectomy, a surgical technique first performed in France, has gained widespread acceptance among surgeons in the United States. The abdominal cavity is inflated by carbon dioxide, a video monitor is inserted via a laparoscope placed periumbilically, and the gallbladder is freed and removed from the liver bed by using small subcostal ports for access and dissection. Intraoperative cholangiography is routinely performed, but uncertainty exists about how best to manage choledocholithiasis. Compared with traditional cholecystectomy, initial reports describing laparoscopic cholecystectomy cite shorter recovery times because no large incisions are made, thus potentially reducing the cost and morbidity of cholecystectomy. A survey of 614 early cases supports these claims, with a reported complication rate of 1.5% and quick resumption of normal activities by patients. Because of its promise for reduced morbidity, laparoscopic cholecystectomy is challenging open cholecystectomy as the therapeutic gold standard for symptomatic cholelithiasis. Thus, the standard to which the nonsurgical gallstone therapies, such as lithotripsy and contact dissolution, will be compared may shift to laparoscopic cholecystectomy. As the laparoscopic complications are similar to those of traditional cholecystectomy, such as abscesses and bile leaks, their percutaneous treatment should not change. PMID:1830188

    Background and Objectives: Single-incision laparoscopic surgery is becoming more widely used, but few combined procedures have been reported. Herein we share our experience with single-incision laparoscopic combined cholecystectomy and appendectomy. Methods: We reviewed data from 26 patients who underwent single-incision laparoscopic combined cholecystectomy and appendectomy between May 1, 2009 and June 1, 2013 at Shengjing Hospital. All the procedures were performed with conventional laparoscopic instruments placed through a single operating portal of entry created within the umbilicus. Results: All the operations were successfully completed without conversion to conventional laparoscopic or open surgery. No intraoperative complications occurred. Patients were satisfied with the therapeutic and cosmetic outcomes. Conclusions: Single-incision laparoscopic combined cholecystectomy and appendectomy appear to be a technically feasible alternative to the standard laparoscopic procedure in simultaneous management of coexisting benign gallbladder and appendix pathologies. Larger studies are required to confirm these findings. PMID:25392641

    Abstract This study aims to introduce an alternative technique for effective single-site robotic cholecystectomy (SSRC) using a reverse port. Proper exposure of Calot's triangle is critical for safe laparoscopic cholecystectomy. Current robotic surgical systems are useful for single-site cholecystectomy. However, in exposing Calot's triangle, the gallbladder is usually retracted in a medial and upward direction, resulting in a narrow triangle. This intraoperative view is a major obstacle to safe laparoscopic cholecystectomy. From October 2013 to October 2014, 55 consecutive patients underwent SSRC by a single surgeon at Yonsei University Severance Hospital. Initially, 5 patients underwent the original robotic single site cholecystectomy technique, and the remaining 50 patients underwent robotic single site cholecystectomy using our reverse port technique. There were no differences between the SSRC-O (original port) group and the SSRC-R (reverse port) group in terms of patient age (P = 0.244), body mass index (P = 0.503), and pathologic conditions of the gallbladder (P = 0.841). Total operation time (132.6 vs 99.12 min; P = 0.009), actual dissection time (51.6 vs 30.28 min; P = 0.001), and console time (84.4 vs 50.46 min; P = 0.001) were all significantly shorter in the SSRC-R group. Mean intraoperative blood loss was minimal in both groups (20 vs 12.4 mL, P = 0.467), and bile spillage occurred in 2 patients of the SSRC-R group. There was one case of laparoscopic conversion in the SSRC-R group. The reverse port technique described in this study successfully widened Calot's triangle and improved the safety of the current robotic surgical system for single-site robotic cholecystectomy.

    Introduction Laparoscopy has been a standard procedure in most medical centres providing surgical services for many years. Both the range and number of laparoscopic procedures performed are constantly increasing. Over the last decade, laparoscopic procedures have been successfully applied both in emergency and oncological surgery. However, treatment costs have become a more important factor in choosing between open or laparoscopic procedures. Aim To present the total real costs of open and laparoscopic cholecystectomy, appendectomy and sigmoidectomy. Material and methods Between 1 May 2010 and 30 March 2015 in the Department of Thoracic Surgery, General and Oncological Surgery, Medical University of Lodz, and in the Department of General Surgery of the Saint John of God Hospital, Lodz, doctors performed 1404 cholecystectomies, 392 appendectomies and 88 sigmoidectomies. A total of 97% of the cholecystectomy procedures were laparoscopic and 3% were open. Similarly, 22% of total appendectomies were laparoscopic and 78% were open, while 9% of sigmoidectomies were laparoscopic and 91% open. Results The requirement for single-use equipment in laparoscopic procedures increases the expense. However, after adding up all other costs, surprisingly, differences between the costs of laparoscopic and open procedures ranged from 451 PLN/€ 114 for laparoscopic operations to 611 PLN/€ 153 for open operations. Conclusions Laparoscopic cholecystectomy, considered the standard surgery for treating gallbladder diseases, is cheaper than open cholecystectomy. Laparoscopic appendectomy and sigmoidectomy are safe methods of minimally invasive surgery, slightly more expensive than open operations. Of all the analyzed procedures, one-day laparoscopic cholecystectomy is the most profitable. The costs of both laparoscopic and open sigmoidectomy are greatly underestimated in Poland. PMID:26649092

    Our objective was to determine the probability threshold for recurrent symptoms at which elective cholecystectomy compared to observation in older patients with symptomatic cholelithiasis is the more effective and cost-effective option. We built a decision model of elective cholecystectomy versus observation in patients >65 presenting with initial episodes of symptomatic cholelithiasis that did not require initial hospitalization or cholecystectomy. Probabilities for subsequent hospitalization, emergency cholecystectomy, and perioperative complications were based on previously published probabilities from a 5 % national sample of Medicare patients. Costs were estimated from Medicare reimbursements and from the Healthcare Cost and Utilization Project. Utilities (quality-adjusted life years, QALYs) were obtained from established literature estimates. Elective cholecystectomy compared to observation in all patients was associated with lower effectiveness (-0.10 QALYs) and had an increased cost of $3,422.83 per patient at 2-year follow-up. Elective cholecystectomy became the more effective option when the likelihood for continued symptoms exceeded 45.3 %. Elective cholecystectomy was both more effective and less costly when the probability for continued symptoms exceeded 82.7 %. An individualized shared decision-making strategy based on these data can increase elective cholecystectomy rates in patients at high risk for recurrent symptoms and minimize unnecessary cholecystectomy for patients unlikely to benefit.

    Purpose: The effectiveness of angiography and embolization in diagnosis and treatment were assessed in a cohort of patients presenting with upper gastrointestinal hemorrhage secondary to hepatic artery pseudoaneurysm following laparoscopic cholecystectomy. Methods: Over a 6-year period 1513 laparoscopic cholecystectomies were carried out in our region. Nine of these patients (0.6%) developed significant upper gastrointestinal bleeding, 5-43 days after surgery. All underwent emergency celiac and selective right hepatic artery angiography. All were treated by coil embolization of the right hepatic artery proximal and distal to the bleeding point. Results: Pseudoaneurysms of the hepatic artery adjacent to cholecystectomy clips were demonstrated in all nine patients at selective right hepatic angiography. In three patients celiac axis angiography alone failed to demonstrate the pseudoaneurysm. Embolization controlled hemorrhage in all patients with no further bleeding and no further intervention. One patient developed a candidal liver abscess in the post-procedure period. All patients are alive and well at follow-up. Conclusion: Selective right hepatic angiography is vital in the diagnosis of upper gastrointestinal hemorrhage following laparoscopic cholecystectomy. Embolization offers the advantage of minimally invasive treatment in unstable patients, does not disrupt recent biliary reconstruction, allows distal as well as proximal control of the hepatic artery, and is an effective treatment for this potentially life-threatening complication.

    Objective: The purpose of this study was to evaluate the results of laparoscopic cholecystectomy in patients with bilharzial portal hypertension. Methods: Patients who had gallstones and bilharzia had ultrasonographic assessment of peri-portal fibrosis, endoscopy, hemagglutination and rectal snip. Operating time, blood loss, hospital stay, time of return to work and operative mortality were recorded. Follow-up was two weeks, six weeks and six months after discharge. Results: Twenty-five out of 450 patients, who had laparoscopic cholecystectomy, suffered from bilharzial portal hypertension. Ten patients had grade 1 varices, 10 had grade 2 varices, and 5 had grade 3 esophageal varices. All patients had varying degrees of peri-portal fibrosis as shown by ultrasound. Rectal snip showed schistosoma mansoni in 5 patients, and a hemagglutination test was positive in all. Two patients had conversion to open cholecystectomy. Mean operating time was 1 hour and 15 minutes. Average blood loss was 50 cc. Mean hospital stay for 23 patients was 48 hours. Average time of return to work was 2 weeks in 23 patients and 6 weeks in the 2 patients who had conversion. Twenty-two patients benefited from the operation. There was no mortality in this series. Conclusions: Laparoscopic cholecystectomy in patients with bilharzial portal hypertension is feasible and has low morbidity. PMID:10917123

    Introduction: There has been no report on Single-Incision Laparoscopic Surgery (SILS) cholecystectomy outcomes since it was first performed in the Anglophone Caribbean in 2009. Methods: A retrospective audit evaluated the clinical outcomes of SILS cholecystectomies at regional hospitals in the 17 Anglophone Caribbean countries. Any cholecystectomy using a laparoscopic approach in which all instruments were passed through one access incision was considered a SILS cholecystectomy. The following data were collected: patient demographics, indications for operation, intraoperative details, surgeon details, surgical techniques, specialized equipment, conversions, morbidity and mortality. Descriptive statistics were generated using SPSS 12.0. Results: There were 85 SILS cholecystectomies in women at a mean age of 37.4 ± 8.5 years with a mean BMI of 30.9 ± 2.8. There were 59 elective and 26 emergent cases. Specialized access platforms were used in the first 35 cases and reusable instruments were passed directly across fascia in the latter 50 cases. The mean operative time was 62.9 ± 17.9 minutes. There was no mortality, 2 conversions to multi-trocar laparoscopy and 5 minor complications. Ambulatory procedures were performed in 43/71 (60.6%) patients scheduled for elective operations. Conclusion: In the Caribbean setting, SILS cholecystectomy is a feasible and safe alternative to conventional multi-trocar laparoscopic cholecystectomy for gallbladder disease. PMID:25324700

    Background: Laparoscopic cholecystectomy is associated with shorter hospital stay and less pain in comparison to open surgery. The aim of this study was to evaluate the effect of intraperitoneal hydrocortisone on pain relief following laparoscopic cholecystectomy. Methods: Sixty two patients were enrolled in a double-blind, randomized clinical trial. Patients randomly received intraperitoneal instillation of either 250 ml normal saline (n=31) or 100 mg hydrocortisone in 250 ml normal saline (n=31) before insufflation of CO2 into the peritoneum. Abdominal and shoulder pain were evaluated using VAS after surgery and at 6, 12, and 24 hours postoperatively. The patients were also followed for postoperative analgesic requirements, nausea and vomiting, and return of bowel function. Results: Sixty patients completed the study. Patients in the hydrocortisone group had significantly lower abdominal and shoulder pain scores (10.95 vs 12.95; P<0.01). The patients were similar regarding analgesic requirements in the recovery room. However, those in the hydrocortisone group required less meperidine than the saline group (151.66 (±49.9) mg vs 61.66 (±38.69) mg; P=0.00). The patients were similar with respect to return of bowel function, nausea and vomiting. No adverse reaction was observed in either group. Conclusion: Intraperitoneal administration of hydrocortisone can significantly decrease pain and analgesic requirements after laparoscopic cholecystectomy with no adverse effects. PMID:23717225

    In an emergency situation shelter space is crucial for people affected by natural hazards. Emergency planners in disaster relief and mass care can greatly benefit from a sound methodology that identifies suitable shelter areas and sites where shelter services need to be improved. A methodology to rank suitability of open spaces for contingency planning and placement of shelter in the immediate aftermath of a disaster is introduced. The Open Space Suitability Index uses the combination of two different measures: a qualitative evaluation criterion for the suitability and manageability of open spaces to be used as shelter sites and another quantitative criterion using a capacitated accessibility analysis based on network analysis. For the qualitative assessment implementation issues, environmental considerations and basic utility supply are the main categories to rank candidate shelter sites. A geographic information system is used to reveal spatial patterns of shelter demand. Advantages and limitations of this method are discussed on the basis of an earthquake hazard case study in the Kathmandu Metropolitan City. According to the results, out of 410 open spaces under investigation, 12.2% have to be considered not suitable (Category D and E) while 10.7% are Category A and 17.6% are Category B. Almost two-thirds (59.55%) are fairly suitable (Category C).

    Introduction Cancer of the gallbladder is a serious diagnostic and therapeutic problem. According to the literature, 30% of cases are not confirmed before surgery. Other cases are detected incidentally by histopathology. Clinical trials and meta-analyses show that incidental gallbladder cancer (iGBC) occurs in 0.19%–2.8% of patients after cholecystectomy. The aim of this study was to analyze the incidence and severity of iGBC in cholecystectomy procedures performed in the surgical department at the 4th Military Teaching Hospital in Wroclaw during the years 1990–2014. Patients and methods In the years 1990–2014, a total of 7,314 cholecystectomies were performed in the surgical department because of cholecystolithiasis: 6,145 were performed using the laparoscopic approach (84.02%), 867 were performed as open surgery (11.8%), and 302 cases required conversion (5.1%). In this group, 5,214 of the patients were females (71.3%) and 2,100 were males (28.7%), with an average age of 54.7 years. Results We found 64 iGBC cases which were confirmed by histopathology. This represented 0.87% of all cases. In this group, 50 patients were females (78.1%) and 14 were males (21.8%), with an average age of 67.1 years. Of this group, 40 patients underwent a classic cholecystectomy, while 24 underwent laparoscopic procedures, out of which 13 cases ultimately required traditional surgery. The histopathology showed 15 carcinomas that were classified as G1 (23.4%), 28 were G2 (43.75%), and 21 were G3 (32.8%). Conclusion iGBC detected after a cholecystectomy due to cholecystolithiasis is a rare disease. We found iGBC in 0.87% of cases, which is on a comparable scale to the world literature. In the case of cancer, we frequently found it necessary to convert to an open surgical procedure. This cancer is more common in females and in people over 60 years of age. PMID:27540304

    Purpose: Advances in laparoscopic techniques have enabled complicated intra-abdominal surgical procedures to be made with less trauma and a better cosmetic appearance. The techniques have been developed by decreasing the number of incisions in conventional laparoscopic procedures in order to increase patient satisfaction. The aim of this study was to compare the results of cholecystectomies made with 3, 2 or a single incision. Method: A total of 95 cholecystectomy patients from Elbistan State Hospital and Suleyman Demirel University Hospital between 2011 and 2013 were prospectively evaluated. The patients were separated into 3 groups as triple incision laparoscopic cholecystectomy (TILC), double incision laparoscopic cholecystectomy (DILC) and single incision laparoscopic cholecystectomy (SILC). Patients were evaluated in respect of demographic characteristics, operation time, success rate, analgesia requirement, length of hospital stay and patient satisfaction. Results: Successful procedures were completed in 40 TILC, 40 DILC and 15 SILC cases. Transfer to open cholecystectomy was not required in any case. The mean duration of operation was 71 mins (range, 55-120 mins) for SILC cases, 45 mins (range, 32-125 mins) for DILC cases and 42 mins (range, 29-96 mins) for TILC cases. The mean time for the SILC cases was statistically significantly longer than the other two groups (p < 0.000). Conclusions: At a comparable level with DILC and TILC, single incision laparosccopic cholecystectomy is a method which can be used without incurring any extra costs or requiring additional instrumentation or training and which has good cosmetic results and a low requirement for analgesia.

    Background Scarless/single-incision laparoscopic cholecystectomy (SILC) is a new procedure. It affords a superior cosmetic outcome when compared to conventional laparoscopic cholecystectomy. We examine the application of this technique using LigaSure via a clipless method. The present study looks at the experience of a single surgeon using this method with initial evaluation of the safety, feasibility, affordability, and benefits of this procedure. Methods Twenty-eight patients underwent transumbilical SILC at Doctors Hospital from January to December, 2014. The cohort included both emergency and elective patients. There was no difference in the preoperative work-up as indicated. To perform the operation, a 2–2.5-cm linear incision was made through the umbilicus and the single port platform utilized. A 10 mm 30-degree laparoscope, a 5 mm LigaSure and straight instruments were used to perform the laparoscopic cholecystectomy procedure. Results All patients except two were operated on successfully. Conversion was considered the placement of an additional epigastric/Right upper quadrant (RUQ) port. The conversion rate to standard LC was 7%. No patient was converted to open cholecystectomy. In the 28 successfully completed patients, the median duration of the operation was 38.5 min and estimated operative blood loss was 24 ml. Patients were commenced on liquid diet immediately on being fully conscious and after return to the ward with an estimated time of 6 h. The mean postoperative hospital stay was 1.4 days. Follow-up visits were conducted for all patients at 2-weeks intervals and continued for 6 weeks after surgery where possible. Two patients developed wound infections. All patients were satisfied with the good cosmetic effect of the surgery. The total satisfaction rate was 100%. Conclusions SILC is a safe and feasible technique for operating with scarless outcomes and reducing perioperative discomfort at the same time. The GelPOINTTM is a safe and feasible

Early, on postoperative day five, endoscopic retrograde cholangiopancreatography (ERCP) requirement after laparoscopic cholecystectomy resolved the biliary leakage problem but resulted with a more complicated clinical picture with an intestinal obstruction and severe abdominal pain. Computed tomography revealed a strangulated hernia from the umbilical trocar site. Increased abdominal pressure during ERCP had strained the weak umbilical trocar site. Emergency surgical intervention through the umbilicus revealed an ischemic small bowel segment which was treated with resection and anastomosis. This report demonstrates that negligence of trocar site closure can result in very early herniation, particularly if an endoscopic intervention is required in the early postoperative period.

    In support of a stall/spin research program, an emergency in-flight egress system is being installed in a light general aviation airplane. To avoid a major structural redesign for a mechanical door, an add-on 11.2 kg pyrotechnic-actuated system was developed to create an opening in the existing structure. The airplane skin will be explosively severed around the side window, across a central stringer, and down to the floor, creating an opening of approximately 76 by 76 cm. The severed panel will be jettisoned at an initial velocity of approximately 13.7 m/sec. System development included a total of 68 explosive severance tests on aluminum material using small samples, small and full scale flat panel aircraft structural mock-ups, and an actual aircraft fuselage. These tests proved explosive sizing/severance margins, explosive initiation, explosive product containment, and system dynamics.

    OBJECTIVE: The authors investigated the preoperative feasibility of using spiral computed tomography (SCT) after intravenous infusion cholangiography (IVC-SCT) for laparoscopic cholecystectomy. SUMMARY BACKGROUND DATA: In laparoscopic cholecystectomy, the aberrant or unusual anatomy of the bile duct and severe inflammation or adhesions around the gallbladder sometimes require a conversion to open surgery. METHODS: Laparoscopic cholecystectomies (LC's) were attempted on 440 patients, and preoperative IVC-SCT also was attempted in all of these patients. Using this spiral scanning technique, the bile ducts, cystic duct, and gallbladder were assessed for contour abnormalities, relative position, and filling defects. Forty-seven patients were diagnosed with having stones in their common bile duct or common hepatic duct. RESULTS: Three-hundred eighty-seven patients out of the 440 patients (88.0%) who were subjected to IVC-SCT had the length and course of their cystic duct successfully determined. Anomalous unions of the cystic duct were seen in 59 (15.2%) of 387 patients with respect to the operative findings, and 48 of 440 patients (10.9%) had severe adhesions to Calot's triangle and the surrounding tissues. In these 48 patients, 45 patients (94%) had a nonvisualized cystic duct on IVC-SCT. The preoperative assessment of the feasibility (dense adhesions obscuring Calot's triangle) of using IVC-SCT demonstrated that the sensitivity, specificity, and accuracy were 93%, 98%, and 94%, respectively. Five patients had to be converted to open surgery, and the overall morbidity rates for patients undergoing laparoscopic cholecystectomy was 0.9% (4 of 440). CONCLUSIONS: The most important factor in assessing the feasibility of using laparoscopic cholecystectomy is not the nonvisualized gallbladder, but the nonvisualized cystic duct on IVC-SCT. IVC-SCT may be of benefit to those patients scheduled to undergo laparoscopic cholecystectomy. Images Figure 1. Figure 2. Figure 3

    Patients with thrombophilic disorder while undergoing intra-abdominal surgery may develop splanchnic vein thrombosis which can have dire consequences. Here we report a case of a 38-year-old female who developed acute Budd–Chiari syndrome after a laparoscopic cholecystectomy. She had polycythemia vera which was not diagnosed before surgery. In this report we want to highlight presurgical evaluation of routine biochemical tests and ultrasonography suggestive of myeloproliferative disorders were missed which led to the Budd–Chiari syndrome. We recommend a meticulous look at the routine evaluation done prior to cholecystectomy is essential. PMID:25755508

    Laparoscopic cholecystectomy is a viable and safe alternative for the treatment of symptomatic gallstones and biliary colic. As surgeons gain more experience with this procedure, contraindications become fewer and indications increase. Well-documented advantages of this approach include less patient discomfort, less surgical scarring, and earlier return to employment. Not previously discussed in the literature, however, are the additional advantages that this procedure holds for a specific subset of patients--namely, those patients that have undergone successful organ transplantation and are receiving immunosuppressive drugs. We report a case of a laparoscopic cholecystectomy in such a patient. PMID:1387737

    Purpose. This prospective observational study compares an innovative approach of Single-Site Multi-Port Per-umbilical Laparoscopic Endo-surgery (SSMPPLE) cholecystectomy with the gold standard—Conventional Multi-port Laparoscopic Cholecystectomy (CMLC)—to assess the feasibility and efficacy of the former. Methods. In all, 646 patients were studied. SSMPPLE cholecystectomy utilized three ports inserted through three independent mini-incisions at the umbilicus. Only the day-to-day rigid laparoscopic instruments were used in all cases. The SSMPPLE cholecystectomy group had 320 patients and the CMLC group had 326 patients. The outcomes were statistically compared. Results. SSMPPLE cholecystectomy had average operative time of 43.8 min and blood loss of 9.4 mL. Their duration of hospitalization was 1.3 days (range, 1–5). Six patients (1.9%) of this group were converted to CMLC. Eleven patients had controlled gallbladder perforations at dissection. The Visual Analogue Scores for pain on postoperative days 0 and 7, the operative time, and the scar grades were significantly better for SSMPPLE than CMLC. However, umbilical sepsis and seroma outcomes were similar. We had no bile-duct injuries or port-site hernias in this study. Conclusion. SSMPPLE cholecystectomy approach complies with the principles of laparoscopic triangulation; it seems feasible and safe method of minimally invasive cholecystectomy. Overall, it has a potential to emerge as an economically viable alternative to single-port surgery. PMID:24876955

    In this paper we proposed a portable fluorescence microscopic imaging system to prevent iatrogenic biliary injuries from occurring during cholecystectomy due to misidentification of the cystic structures. The system consisted of a light source module, a CMOS camera, a Raspberry Pi computer and a 5 inch HDMI LCD. Specifically, the light source module was composed of 690 nm and 850 nm LEDs, allowing the CMOS camera to simultaneously acquire both fluorescence and background images. The system was controlled by Raspberry Pi using Python programming with the OpenCV library under Linux. We chose Indocyanine green(ICG) as a fluorescent contrast agent and then tested fluorescence intensities of the ICG aqueous solution at different concentration levels by our fluorescence microscopic system compared with the commercial Xenogen IVIS system. The spatial resolution of the proposed fluorescence microscopic imaging system was measured by a 1951 USAF resolution target and the dynamic response was evaluated quantitatively with an automatic displacement platform. Finally, we verified the technical feasibility of the proposed system in mouse models of bile duct, performing both correct and incorrect gallbladder resection. Our experiments showed that the proposed system can provide clear visualization of the confluence between the cystic duct and common bile duct or common hepatic duct, suggesting that this is a potential method for guiding cholecystectomy. The proposed portable system only cost a total of $300, potentially promoting its use in resource-limited settings.

    Laparoscopic cholecystectomy is widely accepted nowadays as the gold standard in the treatment of cholelithiasis. This new technique was initially associated with a significant increase in morbidity, and in particular in iatrogenic biliary injuries and arterial haemorrhages, perhaps due to a lack of knowledge of the "laparoscopic anatomy" of the gallbladder pedicle. In this technique the anatomical structures are viewed on a two-dimensional video monitor, and the dissection is performed with long instruments without manual sensitivity. Therefore, the laparoscopic surgeon has to deal with new anatomical views and must be aware of the possible arterial and biliary variants. In this review we describe our technique of laparoscopic cholecystectomy, with particular reference to manoeuvres useful for identifying the various anatomical structures at the gallbladder hilum. In our opinion, it is mandatory to avoid cutting any duct if its identity has yet to be established. For this reason, we pay great attention to the anatomical dissection of Calot's triangle, in order to accurately identify the cystic duct and the cystic artery and any other vascular or biliary structures. Routine intraoperative cholangiography may be useful for identifying the biliary anatomy. When in doubt, the surgeon should not hesitate to convert the procedure to open surgery. PMID:15287636

    Objective Laparoscopic cholecystectomy has become the “gold standard” for benign gallbladder diseases due to its advantages. In the presence of inflammation or fibrosis, the risk of bleeding and bile duct injury is increased during dissection. Laparoscopic partial cholecystectomy (LPC) is a feasible and safe method to prevent bile duct injuries and decrease the conversion (to open cholecystectomy) rates in difficult cholecystectomies where anatomical structures could not be demonstrated clearly. Material and Methods The feasibility, efficiency, and safety of LPC were investigated. The data of 80 patients with cholelithiasis who underwent LPC (n=40) and conversion cholecystectomy (CC) (n=40) were retrospectively examined. Demographic characteristics, ASA scores, operating time, drain usage, requirement for intensive care, postoperative length of hospital stay, surgical site infection, antibiotic requirement and complication rates were compared. Results The median ASA value was 1 in the CC group and 2 in the LPC group. Mean operation time was 123 minutes in the CC group, and 87.50 minutes in the LPC group. Surgical drains were used in 16 CC patients and 4 LPC patients. There was no significant difference between groups in postoperative length of intensive care unit stay (p=0.241). When surgical site infections were compared, the difference was at the limit of statistical significance (p=0.055). Early complication rates were not different (p=0.608) but none of the patients in the LPC group suffered from late complications. Conclusion LPC is an efficient and safe way to decrease the conversion rate. LPC seems to be an alternative procedure to CC with advantages of shorter operating time, lower rates of surgical site infection, shorter postoperative hospitalization and fewer complications in high-risk patients.

    2010-01-01

    Erythropoietic protoporphyria (EPP) is an inherited defect in haem synthesis causing dangerous phototoxic reactions following exposure to wavelengths of light around 400nm. It can cause catastrophic post-operative complications following open surgery, in which environment various safety measures are now routinely employed. The dangers at laparoscopy have never been discussed in the literature, and nor have any specific precautions been recommended. We describe a 35 year old woman with gallstones undergoing prophylactic laparoscopic cholecystectomy to prevent future cholestasis precipitating porphyric liver failure. A pre-operative trial of the cutaneous effects of the laparoscopic light source was performed to assess the potential risk of use within the peritoneal cavity. The procedure was uneventful and the patient suffered no adverse reaction. We suggest that a trial of the effects of the laparoscopic light source on the skin of EPP patients provides valid reassurance regarding the safety of the laparoscopy for short surgical procedures.

    Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    Background and Objectives: Single-port laparoscopic cholecystectomy (SPLC) was introduced to improve patients' postoperative quality of life and cosmesis over the conventional approach (CLC). The purpose of this case–control study was to compare the outcome of SPLC with that of CLC in a specific disease: gall bladder (GB) polyps. Methods: Eligible for the study were all patients with GB polyps who underwent laparoscopic cholecystectomy between June 1, 2009, and June 30, 2011. The 112 patients studied (56 each for SPLC and CLC) were matched by using a propensity score that included gender, age, body mass index (BMI), American Society of Anesthesiologists (ASA) score, history of previous abdominal operation, and pathology outcome. To avoid selection bias caused by the surgeon's choice (often dependent on the degree of inflammation) and to investigate the efficacy of SPLC for a single disease, GB polyps, we excluded patients with acute or chronic cholecystitis. Results: Characteristics of the patients matched by a propensity score between SPLC and CLC showed no significant difference. Incidentally detected malignancy was in postoperative pathology in cases in both groups. Although operative time was shorter for SPLC, there was no significant difference in time between the 2 groups. There were 3 open conversions in the CLC group, and an additional port was used in the SPLC group. There was no difference between the groups in hospital stay and postoperative complications. Conclusion: In the management of GB polyps, the operative results of SPLC are comparable to those of CLC. We conclude that SPLC is as safe as CLC and has the potential for greater cosmetic satisfaction for patients than CLC. Further trials for objective appraisal of cosmetic outcomes are needed.

    Purpose Single-fulcrum laparoscopic cholecystectomy (SFLC) is a variant type of single incision and multi-port technique that does not use specialized one-port devices or articulating instruments. We retrospectively compared perioperative outcomes of SFLC with those of conventional laparoscopic cholecystectomy (CLC). Materials and Methods Between March 2009 and December 2010, SFLC was performed in 130 patients. Among them, 105 patients with uncomplicated gallbladder disease (no inflammation or no clinical symptoms) and another 105 patients who underwent CLC were selected for this study. Results There was no open conversion. In comparison with CLC, SFLC was performed more often in young (46.4±12.2 years vs. 52.5±13.6 years, p=0.001) female patients (80/25 vs. 62/43, p=0.008). The total operation time was longer in SFLC (56.7±14.1 min vs. 47.5±17.1 min, p<0.001), but pain scores immediately after operation and at discharge time were lower for SFLC than for CLC (3.1±1.3 vs. 4.0±1.9, p<0.001, 2.0±0.9 vs. 2.4±0.8, p=0.002). Total cost was lower for SFLC than for CLC (US $ 1801±289.9 vs. US $ 2003±617.4, p=0.004). There were no differences in hospital stay or complication rates. Conclusion SFLC showed greater technical feasibility and cost benefits in treating uncomplicated benign gallbladder disease than CLC. PMID:24142653

    Aquaporins (AQPs) are water channels allowing fast and passive diffusion of water across cell membranes. It was hypothesized that AQPs contribute to cell elongation processes by allowing water influx across the plasma membrane and the tonoplast to maintain adequate turgor pressure. Here, we report that, in Arabidopsis (Arabidopsis thaliana), the highly abundant tonoplast AQP isoforms AtTIP1;1, AtTIP1;2, and AtTIP2;1 facilitate the emergence of new lateral root primordia (LRPs). The number of lateral roots was strongly reduced in the triple tip mutant, whereas the single, double, and triple tip mutants showed no or minor reduction in growth of the main root. This phenotype was due to the retardation of LRP emergence. Live cell imaging revealed that tight spatiotemporal control of TIP abundance in the tonoplast of the different LRP cells is pivotal to mediating this developmental process. While lateral root emergence is correlated to a reduction of AtTIP1;1 and AtTIP1;2 protein levels in LRPs, expression of AtTIP2;1 is specifically needed in a restricted cell population at the base, then later at the flanks, of developing LRPs. Interestingly, the LRP emergence phenotype of the triple tip mutants could be fully rescued by expressing AtTIP2;1 under its native promoter. We conclude that TIP isoforms allow the spatial and temporal fine-tuning of cellular water transport, which is critically required during the highly regulated process of LRP morphogenesis and emergence.

    The case presented deals with the complicated course of a laparoscopic cholecystectomy in a 45-year-old female patient due to cholecystolithiasis. The patient complained that during the operation an injury to the small intestine occurred, which was only operatively treated at midday of the despite massive pain and insufficient pain treatment. The intervention was claimed to have resulted in mental and physical suffering. The case is assessed by two independent experts in the sense of a "scientifically founded comment" with respect to the decision of the arbitration board and taking the surgical standards into consideration.

    Single Incision Laparoscopic Surgery (SILS) is a recent surgical technique, first described in the 1990s. Its aim is to optimize the esthetic result offered by laparoscopy by minimizing the number of abdominal incisions. Various preliminary studies have been carried out on the application of SILS, especially in cholecystectomy and appendectomy. This study evaluates the preliminary results of cholecystectomy by SILS (SILS™ Port) conducted between October 2009 and February 2011 on 21 patients (4 men and 17 women) with a mean age of 49.9 years and a mean Body Mass Index (BMI) of 22.8. All patients were treated by the same team, which had previously undergone six months' simulator training. There were two main selection criteria, both evaluated intraoperatively: absence of adhesions and of significant inflammatory sequelae from previous cholecystitis; and suitable distance between gallbladder and SILS access port. Conversion to traditional laparoscopy was necessary in just two cases, while an accessory trocar was introduced in another two cases. Conversion to open surgery was not necessary in any case. One case of SILS cholecystectomy was complicated by postoperative bile leakage, which was treated conservatively, as the fistula had a low output. The mean duration of hospitalization was 3.6 days. This preliminary experience led us to conclude that SILS is safe and highly satisfactory in the postoperative phase, thanks to the reduced need for painkillers and the improved esthetic result.

    AIM: To present and integrate findings of studies investigating the effects of laparoscopic cholecystectomy on various aspects of lung function. METHODS: We extensively reviewed literature of the past 24 years concerning the effects of laparoscopic cholecystectomy in comparison to the open procedure on many aspects of lung function including spirometric values, arterial blood gases, respiratory muscle performance and aspects of breathing control, by critically analyzing physiopathologic interpretations and clinically important conclusions. A total of thirty-four articles were used to extract information for the meta-analysis concerning the impact of the laparoscopic procedure on lung function and respiratory physiopathology. The quality of the literature reviewed was evaluated by the number of their citations and the total impact factor of the corresponding journals. A fixed and random effect meta-analysis was used to estimate the pooled standardized mean difference of studied parameters for laparoscopic (LC) and open (OC) procedures. A crude comparison of the two methods using all available information was performed testing the postoperative values expressed as percentages of the preoperative ones using the Mann-Whitney two-sample test. RESULTS: Most of the relevant studies have investigated and compared changes in spirometric parameters.The median percentage and interquartile range (IQR) of preoperative values in forced vital capacity (FVC), forced expiratory volume in 1 s and forced expiratory flow (FEF) at 25%-75% of FVC (FEF25%-75%) expressed as percentage of their preoperative values 24 h after LC and OC were respectively as follows: [77.6 (73.0, 80.0) L vs 55.4 (50.0, 64.0) L, P < 0.001; 76.0 (72.3, 81.0) L vs 52.5 (50.0, 56.7) L, P < 0.001; and 78.8 (68.8, 80.9) L/s vs 60.0 (36.1, 66.1) L/s, P = 0.005]. Concerning arterial blood gases, partial pressure of oxygen [PaO2 (kPa)] at 24 or 48 h after surgical treatment showed reductions that were significantly

    During laparoscopic cholecystectomy, gallbladder perforation has been reported, leading to bile leak and spillage of gallstones into the peritoneum. Because the consequences can be dangerous, conversion to laparotomy as an instant management for gallstone spillage is one of the topics of current discussion in laparoscopic cholesystectomy. In this article, we discussed the option of not converting to laparotomy after intraperitoneal gallstone spillage as an acceptable approach to management or not.A prospectively maintained database of 1528 consecutive laparoscopic cholecystectomies performed during a 10-year period at the 4th Surgical Clinic of The Ankara Numune Education and Research Hospital was analyzed. Perforations resulting in gallstone spillage into the abdominal cavity were documented in 58 (3.8%) patients. Among those 58 patients seven (12%) experienced complications from retained stones. To maintain acceptable management of such patients, surgeons should inform each patient preoperatively that stones may be spilled. In the event of spillage, the patient should be informed postoperatively, and followed closely for complications. Follow-up should not waste time and money with unnecessary examinations, and it should avoid psychological trauma to the patient with a wrong diagnosis of cancer as a stone may mimic cancer radiologically. Thus the surgeon should not hesitate to record the events and inform the patient about the spillage of the stones and possible consequences. PMID:15770380

    Background and Objectives: Laparoscopic cholecystectomy (LC) using surgical electrocautery is considered to be the gold standard procedure for the treatment of uncomplicated cholecystitis and cholelithiasis. The objective of the current study was to evaluate the effectiveness and safety of the Harmonic scalpel, an advanced laparoscopic technique associated with less thermal damage in LC, when compared to electrocautery. Methods: From October 2010 through June 2013, a total of 198 patients were randomly allocated to LC with a Harmonic scalpel (experimental group, 117 patients) or conventional monopolar electrocautery (control group, 81 patients). The main outcome measures were operative time, blood loss, conversion to laparotomy, postoperative hospital stay, post-LC pain, and cost effectiveness. Results: The 2 groups were comparable with respect to baseline patient characteristics. When compared to conventional monopolar electrocautery, there were no significant reductions in the operative time, bleeding, frequency of conversion to laparotomy, and duration of postoperative recovery with the Harmonic scalpel (P > .05 for all). Conclusions: Laparoscopic cholecystectomy using conventional monopolar electrocautery is as effective and safe as that with the Harmonic scalpel, for treating uncomplicated cholecystitis and cholelithiasis.

    Public health and financial aspects of cholecystectomy related bile duct injury (BDI) are highlighted in a National Cholecystectomy Survey carried out through 'datamining' the Federal State Medical Records Summaries and Financial Summaries of all Belgian hospitals in 1997. All cancer diagnoses, children < or = 10 years, cholecystectomies performed as an abdominal co-procedure or patients having undergone other non-related surgery were excluded from the study. 10.595 laparoscopic (LC) and 1.033 open cholecystectomies (OC) as well as 137 secondary BDI treatments (LC/OC) were included in the survey (total 11.765). Both LC and OC groups turned out to be significantly different as to distribution of patient's age and APR-DRG severity classes. Composite criteria in terms of ICD-9-CM and billing codes were elaborated to classify: 1) primary, intra-operatively detected and treated BDI (N = 30), 2) primary delayed BDI treatments (N = 38), 3) secondary BDI treatments (N = 137), 4) non-BDI abdomino-surgical complications (N = 119), 4) uneventful laparoscopic (N = 7.476) and 5) uneventful open cholecystectomy (N = 681). Complication rates, community costs of LC and OC groups, incidence of preoperative ERCP and/or intra-operative cholangiography as well as interventions for complications were studied. Incidence of cholecystectomy related BDI was 0.37% in LC, 2.81% in OC and 0.58% overall. Average costs amounted to [symbol: see text] 1.721 for uneventful LC, [symbol: see text] 2.924 for uneventful OC, [symbol: see text] 7.250 for primary, intra-operatively detected and immediately treated BDI [symbol: see text] 9.258 for primary delayed BDI treatments, [symbol: see text] 6.076 for secondary BDI treatments and [symbol: see text] 10.363 for non-BDI abdomino-surgical complications. In conclusion BDI with cholecystectomy reveals to be a serious complication increasing the overall average cost factor ninefold if not detected intra-operatively, in which case the raise is only fourfold

    Suture urolithiasis is an unusual but recognised phenomenon following surgery on the urinary tract. We report a case in a 30-year-old man who sustained a gunshot injury to the left ureter in Burundi and underwent open ureteric repair in a regional hospital. He migrated to the UK and presented one year later with left loin pain. An intravenous urogram revealed two foci of calcification to the left of L3, within a peri-ureteric position. The patient underwent left-sided ureteroscopy where two calculi each formed around a nylon suture were discovered within a ureteric pseudo-diverticulum, and basketed. This is the first reported case of suture urolithiasis occurring following ureteric surgery. PMID:26989371

    who were discharged as day-patient laparoscopic cholecystectomy patients were not reported in any trial. There was no significant difference in the proportion of patients who required conversion to open cholecystectomy (2 trials; 4/63 (weighted proportion 6.4%) in the robot assistant group versus 5/70 (7.1%) in the human assistant group; RR 0.90; 95% CI 0.25 to 3.20). There was no significant difference in the operating time between the two groups (4 trials; 324 patients; MD 5.00 minutes; 95% CI −0.55 to 10.54). In one trial, about one sixth of the laparoscopic cholecystectomies in which a robot assistant was used required temporary use of a human assistant. In another trial, there was no requirement for human assistants. One trial did not report this information. It appears that there was little or no requirement for human assistants in the other three trials. There were no randomised trials comparing one type of robot versus another type of robot. Authors’ conclusions Robot assisted laparoscopic cholecystectomy does not seem to offer any significant advantages over human assisted laparoscopic cholecystectomy. However, all trials had a high risk of systematic errors or bias (that is, risk of overestimation of benefit and underestimation of harm). All trials were small, with few or no outcomes. Hence, the risk of random errors (that is, play of chance) is high. Further randomised trials with low risk of bias or random errors are needed. PMID:22972093

    Elective laparoscopic cholecystectomies are common outpatient surgical procedures. After briefly discussing cholecystectomy and its indications, best practices in phase I, phase II, and phase III recovery are discussed. Typical pharmaceutical regimens for controlling pain and postoperative nausea and vomiting are summarized. By implementing best practices, nurses can prevent and recognize complications. The criteria for discharge, extended recovery, and inpatient admission are discussed, along with the required patient discharge teaching using the teach-back technique, as well as patient and family teaching needs in the immediate postoperative period. Nurses can optimize the patient's surgical experience and promote safety by implementing best practices in all phases of recovery from laparoscopic cholecystectomy. PMID:26119606

    Though variations of intrahepatic biliary anatomy are quite common, duplication of the extrahepatic biliary system is extremely rare and reported infrequently in the literature. Laparoscopic cholecystectomy is one of the most common general surgery procedures performed. Unfortunately, iatrogenic bile duct injuries can contribute to significant morbidity including hospital readmissions, infectious complications and death. Anomalous extrahepatic biliary anatomy may be one of the factors, which increases the likelihood of bile duct injury during laparoscopic cholecystectomy. We present a case of an iatrogenic bile duct injury that occurred during a laparoscopic cholecystectomy, in which a duplicated extrahepatic biliary system was identified intraoperatively during the definitive operative repair.

    The most significant forces that are changing the business world and the society behaviors in this beginning of the twenty-first century can be identified into the globalization of the economy, technological evolution and convergence, change of the workers' expectations, workplace diversity and mobility, and mostly, knowledge and learning as major organizational assets. But which type of ­learning dynamics must be nurtured and pursued within the organizations, today, in order to generate valuable knowledge and its effective applications? After a brief discussion on the main changes observable in management, ICT and society/workplace in the last years, this chapter aims to answer to this question, through the proposition of the “Π-shaped” profile (a new professional archetype for leading change), and through the discussion of the open networked “i-Learning” model (a new framework to “incubate” innovation in learning processes). Actually, the “i” stands for “innovation” (to highlight the nature of the impact on traditional ­learning model), but also it stands for “incubation” (to underline the urgency to have new environments in which incubating new professional profiles). Specifically, the main key characteristics at the basis of the innovation of the learning processes will be ­presented and described, by highlighting the managerial, technological and societal aspects of their nature. A set of operational guidelines will be also ­provided to ­activate and sustain the innovation process, so implementing changes in the strategic dimensions of the model. Finally, the “i-Learning Radar” is presented as an operational tool to design, communicate and control an “i-Learning experience”. This tool is represented by a radar diagram with six strategic dimensions of a ­learning initiative.

    Introduction Misidentification of the extrahepatic bile duct anatomy during laparoscopic cholecystectomy (LC) is the main cause of bile duct injury. Easier intraoperative recognition of the biliary anatomy may be accomplished by using near-infrared fluorescence (NIRF) imaging after an intravenous injection of indocyanine green (ICG). Promising results were reported for successful intraoperative identification of the extrahepatic bile ducts compared to conventional laparoscopic imaging. However, routine use of ICG fluorescence laparoscopy has not gained wide clinical acceptance yet due to a lack of high-quality clinical data. Therefore, this multicentre randomised clinical study was designed to assess the potential added value of the NIRF imaging technique during LC. Methods and analysis A multicentre, randomised controlled clinical trial will be carried out to assess the use of NIRF imaging in LC. In total, 308 patients scheduled for an elective LC will be included. These patients will be randomised into a NIRF imaging laparoscopic cholecystectomy (NIRF-LC) group and a conventional laparoscopic cholecystectomy (CLC) group. The primary end point is time to ‘critical view of safety’ (CVS). Secondary end points are ‘time to identification of the cystic duct (CD), of the common bile duct, the transition of CD in the gallbladder and the transition of the cystic artery in the gallbladder, these all during dissection of CVS’; ‘total surgical time’; ‘intraoperative bile leakage from the gallbladder or cystic duct’; ‘bile duct injury’; ‘postoperative length of stay’, ‘complications due to the injected ICG’; ‘conversion to open cholecystectomy’; ‘postoperative complications (until 90 days postoperatively)’ and ‘cost-minimisation’. Ethics and dissemination The protocol has been approved by the Medical Ethical Committee of Maastricht University Medical Center/Maastricht University; the trial has been registered at Clinical

    There are more than 50 different techniques of laparoscopic cholecystectomy (LC) available in literature mainly due to modifications by surgeons in aim to improve postoperative outcome and cosmesis. These modifications include reduction in port size and/or number than what is used in standard LC. There is no uniform nomenclature to describe these different techniques so that it is not possible to compare the outcomes of different techniques. We brief the advantages and disadvantages of each of these techniques and suggest the situation where particular technique would be useful. We also propose a nomenclature which is easy to remember and apply, so that any future comparison will be possible between the techniques. PMID:25883450

    AIM: To evaluate the demographic and clinical parameters affecting the outcomes of ambulatory laparoscopic cholecystectomy (ALC) in terms of pain, nausea, anxiety level, and satisfaction of patients in a tertiary health center. MATERIALS AND METHODS: ALC was offered to 60 patients who met the inclusion criteria. Follow-up (questioning for postoperative pain or discomfort, nausea or vomiting, overall satisfaction) was done by telephone contact on the same day at 22:00 p.m. and the first day after surgery at 8: 00 a.m. and by clinical examination one week after operation. STAI I and II data were used for proceeding to the level of anxiety of patients before and/or after the operation. RESULTS: Sixty consecutive patients, with a mean age of 40.6 ± 8.1 years underwent ALC. Fifty-five (92%) patients could be sent to their homes on the same day but five patients could not be sent due to anxiety, pain, or social indications. Nausea was reported in four (6.7%) cases and not associated with any demographic or clinical features of patients. On the other hand, pain has been reported in 28 (46.7%) cases, and obesity and shorter duration of gallbladder disease were associated with the increased pain perception (P = 0.009 and 0.004, respectively). Preopereative anxiety level was significantly higher among patients who could not complete the ALC procedure (P = 0.018). CONCLUSION: Correct management of these possible adverse effects results in the increased satisfaction of patients and may encourage this more cost-effective and safe method of laparoscopic cholecystectomy.

    This retrospective cohort study examined the relationship between a cholecystectomy and the subsequent risk of peptic ulcers using a population-based database. Data for this study were retrieved from the Taiwan Longitudinal Health Insurance Database 2005. This study included 5209 patients who had undergone a cholecystectomy for gallstones and 15,627 sex- and age-matched comparison patients. We individually tracked each patient for a 5-year period to identify those who subsequently received a diagnosis of peptic ulcers. We found that of the 20,836 sampled patients, 2033 patients (9.76%) received a diagnosis of peptic ulcers during the 5-year follow-up period: 674 from the study group (12.94% of the patients who underwent a cholecystectomy) and 1359 from the comparison group (8.70% of the comparison patients). The stratified Cox proportional hazard regressions showed that the adjusted hazard ratio (HR) for peptic ulcers during the 5-year follow-up period was 1.48 (95% CI = 1.34~1.64) for patients who underwent a cholecystectomy than comparison patients. Furthermore, the adjusted HRs of gastric ulcers and duodenal ulcers during the 5-year follow-up period were 1.70 and 1.71, respectively, for patients who underwent a cholecystectomy compared to comparison patients. This study demonstrated a relationship between a cholecystectomy and a subsequent diagnosis of peptic ulcers. PMID:27469240

    Background/Aims Published studies suggest that socioeconomic factors contribute to increasing cholecystectomy rates for biliary dyskinesia (BD). The aim of this study was to identify factors driving admissions and operations for BD by examining regional variability in hospitalizations and cholecystectomies for this disorder. Methods Annual hospitalizations and cholecystectomy rates for biliary diseases were assessed using the State Inpatient Databases of the Agency for Healthcare Research and Quality based on diagnosis codes for biliary dyskinesia, cholecystolithiasis and cholecystitis. Results Annual admissions for BD varied nearly sevenfold among different states within the United States. Hospitalizations for gallstone disease and its complication showed less variability, differing 2-fold between states. Nearly 70% of admissions for BD and about 85% of admissions for gallstone disease resulted in cholecystectomies. Higher admission rates for BD were best predicted by high overall hospitalization rates, admission rate for gallstone disease and the physician workforce within a state. Cholecystectomy rates for BD were higher in states with low population density and high rates of cholecystectomy for gallstone disease. Conclusions These data suggest that established medical practice patterns significantly contribute to the variability in admissions and operations for biliary dyskinesia. The findings also indicate that lower thresholds for operative interventions are an important determinant in the approach to this disorder. Considering the benign course of functional illnesses, the bar for surgical interventions should be raised rather than lowered; in addition active conservative treatment options should be developed for these patients.

    Introduction: Tactic of emergency closing of soft tissue defect allows to significantly improve the treatment results concerning patients with severe open fractures. However, a number of certain factors make the implementation of this tactic rather difficult. Injured people’s unstable conditions are mong these crucial factors which include, polytrauma in lots of cases, absence of exact recommendations for recovery terms, choice of definite tissue flaps and a type of circulation. The Aim of Study: is to develop exact, usable and in practice algorithm of emergency reconstruction of leg soft tissues in patients with severe open tibia fractures, based on the usage of the most foolproof and simple methods. Data (Patients) and Methods: 85 patients with open tibia fractures complicated by soft tissue defects were included in our study. Patients were divided into two groups. The control group consisted of 56 patients. Soft tissue reconstruction in this group was provided without an exact algorithm, after continuous attempts on local healing. After analyzing the treatment process and the treatment results we have developed the algorithm of emergency soft tissue reconstruction. It was used in 29 patients (the study group). This algorithm allows choosing optimal timing for tissue reconstruction and appropriate method to be applied, depending on the patient’s condition, the mechanism of soft tissue defect formation, and its square and localization. Results: We observed a statistical decrease in deep wound infection frequency, partial tibia necrosis frequency, chronic osteomyelitis frequency, duration of hospitalization in patients with severe open tibia fractures because of using our algorithm.

    Ojbective: To evaluate the relationship among appropriateness of the use of cholecystectomy and outcomes. Summary Background Data: The use of cholecystectomy varies widely across regions and countries. Explicit appropriateness criteria may help identify suitable candidates for this commonly performed procedure. This study evaluates the relationship among appropriateness of the use of cholecystectomy and outcomes. Methods: Prospective observational study in 6 public hospitals in Spain of all consecutive patients on waiting lists to undergo cholecystectomy for nonmalignant disease. Explicit appropriateness criteria for the use of cholecystectomy were developed by a panel of experts using the RAND appropriateness methodology and applied to recruited patients. Patients were asked to complete 2 questionnaires that measure health-related quality of life—the Short Form 36 (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI)—before the intervention and 3 months after it. Results: Patients judged as being appropriate candidates for cholecystectomy, using the panel's explicit appropriateness criteria, had greater improvements in the bodily pain, vitality, and social function domains of the SF-36 than those judged to be inappropriate candidates. They also demonstrated improvements in the GIQLI's physical impairment domain. Interventions judged as inappropriate were performed primarily among patients without symptoms of cholelithiasis. Those asymptomatic had a lower improvement in the bodily pain, social functioning, and physical summary scale of the SF-36 and in the symptomatology, physical impairment, and total score domains of the GIQLI. Conclusions: These results suggest a direct relationship between the application of explicit appropriateness criteria and better outcomes, as measured by health-related quality of life. They also indicate that patients without symptoms are not good candidates for cholecystectomy. PMID:15621998

    Purpose. Laparoscopic cholecystectomy (LC) is the treatment of choice for gallstones. There is an increased incidence of bile duct injuries in LC compared with the open technique. Isolated right segmental hepatic duct injury (IRSHDI) represents a challenge not only for management but also for diagnosis. We present our experience in the management of IRSHDI, with long-term follow-up after treatment by a multidisciplinary approach. Methods. Twelve consecutive patients (9 women, mean age 48 years) were identified as having IRSHDI. Patients' demographics, clinical presentation, management and outcome were collected for analysis. The mean follow-up was 44 months (range 2-90 months). Results. Three patients had the LC immediately converted to open surgery without repair of the biliary injury before referral. Treatments before referral included endoscopic retrograde cholangiopancreatography (ERCP), percutaneous drainage and surgery, isolated or in combination. The median interval from LC to referral was 32 days. Eleven patients presented with biliary leak and biloma, one with obstruction of an isolated right hepatic segment. Post-referral management of the biliary lesion used a combination of ERCP stenting, percutaneous drainage and stent placement and surgery. In 6 of 12 patients ERCP was the first procedure, and in only one case was IRSHDI identified. In 6 patients, percutaneous transhepatic cholangiography (PTC) was performed first and an isolated right hepatic segment was demonstrated in all. The final treatment modality was endoscopic management and/or percutaneous drainage and stenting in 6 patients, and surgery in 6. The mean follow-up was 44 months. No mortality or significant morbidity was observed. Conclusion. Successful management of IRSHDI after LC requires adequate identification of the lesion, and multidisciplinary treatment is necessary. Half of the patients can be treated successfully by nonsurgical procedures.

    The Mirizzi syndrome (MS) is an impacted stone in the cystic duct or Hartmann's pouch that mechanically obstructs the common bile duct (CBD). We would like to report laparoscopic subtotal cholecystectomy (SC) and resection of cholecystocolic fistula by the help of Tri-Staple™ in a case with type V MS and cholecystocolic fistula, for first time in the literature. A 24-year-old man was admitted to emergency department with the complaint of abdominal pain, intermittent fever, jaundice, and diarrhea. Two months ago with the same complaint, ERCP was performed. Laparoscopic resection of cholecystocolic fistula and subtotal cholecystectomy were performed by the help of Tri-Staple. At the eight-month follow-up, he was symptom-free with normal liver function tests. In a patient with type V MS and cholecystocolic fistula, laparoscopic resection of cholecystocolic fistula and SC can be performed by using Tri-Staple safely. PMID:26904324

    AIM: To compare the safety of single-port laparoscopic cholecystectomies with standard four-port cholecystectomies. METHODS: Between January 2011 and December 2012 datas were gathered from 100 consecutive patients who received a single-port cholecystectomy. Patient baseline characteristics of all 100 single-port cholecystectomies were collected (body mass index, age, etc.) in a database. This group was compared with 100 age-matched patients who underwent a conventional laparoscopic cholecystectomy in the same period. Retrospectively, per- and postoperative data were added. The two groups were compared to each other using independent t-tests and χ2-tests, P values below 0.05 were considered significantly different. RESULTS: No differences were found between both groups regarding baseline characteristics. Operating time was significantly shorter in the total single-port group (42 min vs 62 min, P < 0.05); in procedures performed by surgeons the same trend was seen (45 min vs 59 min, P < 0.05). Peroperative complications between both groups were equal (3 in the single-port group vs 5 in the multiport group; P = 0.42). Although not significant less postoperative complications were seen in the single-port group compared with the multiport group (3 vs 9; P = 0.07). No statistically significant differences were found between both groups with regard to length of hospital stay, readmissions and mortality. CONCLUSION: Single-port laparoscopic cholecystectomy has the potential to be a safe technique with a low complication rate, short in-hospital stay and comparable operating time. Single-port cholecystectomy provides the patient an almost non-visible scar while preserving optimal quality of surgery. Further prospective studies are needed to prove the safety of the single-port technique. PMID:26328034

    A definition of a diffuse field applicable to open heterogeneous systems is proposed. The identity between the Green's function of the structure and the diffuse field's correlations is proved. The Green's function that emerges from the correlation is found to be the full Green's function of the medium, symmetrized in time, with all reflections and scatterings and propagation modes. This is in contrast to suggestions that the correlation is the ballistic Green's function only, or the Green's function of a homogeneous effective medium. .

    Purpose The aim of this study was to investigate the risk factors for conversion to conventional laparoscopic cholecystectomy (CLC) in single incision laparoscopic cholecystectomy (SILC) along with the proposal for procedure selection guidelines in treating patients with benign gallbladder (GB) diseases. Methods SILC was performed in 697 cases between April 2010 and July 2014. Seventeen cases (2.4%) underwent conversion to conventional LC. We compared these 2 groups and analyzed the risk factors for conversion to CLC. Results In univariate analysis, American Society of Anesthesiologist score > 3, preoperative percutaneous transhepatic GB drainage status and pathology (acute cholecystitis or GB empyema) were significant risk factors for conversion (P = 0.010, P = 0.019 and P < 0.001). In multivariate analysis, pathology (acute cholecystitis or GB empyema) was significant risk factors for conversion to CLC in SILC (P < 0.001). Conclusion Although SILC is a feasible method for most patients with benign GB disease, CLC has to be considered in patients with acute cholecystitis or GB empyema because it is likely to result in inadequate visualization of the Calot's triangle and greater bleeding risk.

    The open government initiatives have provided tremendous data resources for the transportation system and emergency services in urban areas. This paper proposes a traffic simulation framework using high temporal resolution demographic data and real time open government data for evacuation planning and operation. A comparison study using real-world data in Seattle, Washington is conducted to evaluate the framework accuracy and evacuation efficiency. The successful simulations of selected area prove the concept to take advantage open government data, open source data, and high resolution demographic data in emergency management domain. There are two aspects of parameters considered in this study: user equilibrium (UE) conditions of traffic assignment model (simple Non-UE vs. iterative UE) and data temporal resolution (Daytime vs. Nighttime). Evacuation arrival rate, average travel time, and computation time are adopted as Measure of Effectiveness (MOE) for evacuation performance analysis. The temporal resolution of demographic data has significant impacts on urban transportation dynamics during evacuation scenarios. Better evacuation performance estimation can be approached by integrating both Non-UE and UE scenarios. The new framework shows flexibility in implementing different evacuation strategies and accuracy in evacuation performance. The use of this framework can be explored to day-to-day traffic assignment to support daily traffic operations.

    Feasibility and safety of laparoscopic cholecystectomy during pregnancy for patients with symptomatic or complicated gallstone disease is well established. Laparoendoscopic single-site cholecystectomy (LESS-chole) is a new modality in which the entire surgery is undertaken via a transumbilical incision. We describe a 33-year-old patient who underwent a LESS-chole in the 20th week of pregnancy for gallstone disease complicated by episodes of obstructive jaundice and acute pancreatitis. This is the first reported case of LESS-chole performed using conventional laparoscopic instruments. The technical aspects as well as the various perioperative measures utilized to undertake this procedure safely are outlined. PMID:24250067

    AIM: To investigate the results of endoscopic treatment of postoperative biliary leakage occurring after urgent cholecystectomy with a long-term follow-up. METHODS: This is an observational database study conducted in a tertiary care center. All consecutive patients who underwent endoscopic retrograde cholangiography (ERC) for presumed postoperative biliary leakage after urgent cholecystectomy in the period between April 2008 and April 2013 were considered for this study. Patients with bile duct transection and biliary strictures were excluded. Biliary leakage was suspected in the case of bile appearance from either percutaneous drainage of abdominal collection or abdominal drain placed at the time of cholecystectomy. Procedural and main clinical characteristics of all consecutive patients with postoperative biliary leakage after urgent cholecystectomy, such as indication for cholecystectomy, etiology and type of leakage, ERC findings and post-ERC complications, were collected from our electronic database. All patients in whom the leakage was successfully treated endoscopically were followed-up after they were discharged from the hospital and the main clinical characteristics, laboratory data and common bile duct diameter were electronically recorded. RESULTS: During a five-year period, biliary leakage was recognized in 2.2% of patients who underwent urgent cholecystectomy. The median time from cholecystectomy to ERC was 6 d (interquartile range, 4-11 d). Endoscopic interventions to manage biliary leakage included biliary stent insertion with or without biliary sphincterotomy. In 23 (77%) patients after first endoscopic treatment bile flow through existing surgical drain ceased within 11 d following biliary therapeutic endoscopy (median, 4 d; interquartile range, 2-8 d). In those patients repeat ERC was not performed and the biliary stent was removed on gastroscopy. In seven (23%) patients repeat ERC was done within one to fourth week after their first ERC

    'Single-sitting' laparoscopic cholecystectomy followed by endoscopic common bile duct clearance is emerging as a viable option for management of cholelithiasis and concomitant choledocholithiasis. The only disadvantage of the procedure is logistical since it requires co-ordination between two teams-the surgeons and the endoscopists. This limitation can be overcome in centres where both the procedures are performed by one team. With a considerable experience in endoscopy, we conducted a prospective study in a select group of patients to assess the feasibility of this single-sitting approach. The study included 38 patients with a radiological diagnosis of choledocholithiasis or jaundice at presentation. After laparoscopic cholecystectomy, the patients were turned prone and subjected to endoscopic retrograde cholangiogram, sphincterotomy and extraction of the common bile duct stone. The procedure was successful in 33 (87 %) of patients. The mean procedure time and hospital stay were 2 h, 20 min and 2 days, respectively. None of the patients had any major complications. We conclude that in a select group of patients, single-sitting laparoscopic cholecystectomy followed by endoscopic clearance of the common bile duct stone is safe and effective. PMID:26730094

    Background Massive upper gastrointestinal hemorrhage can be the dominant symptom of decompensated liver cirrhosis, varices and ulcerations in the upper gastrointestinal tract. Postoperative complications are known to lead to these bleedings. Commonly, emergency endoscopy will be performed. Here we report of a patient with extensive bleeding caused by an aneurysma spurium of the arteria hepatica dextra induced by a laparoscopic cholecystectomy. The condition was diagnosed by the Doppler ultrasound scan of the liver. Case presentation Initially the source of the gastrointestinal bleeding was caused by an ulcus Dieulafoy in the jejunum which was stopped by clipping. Continous bleeding was observed and traced to a rare complication of a laparoscopic cholecystectomy due to a gallbladder empyema. After surgical intervention the patient developed an aneurysma spurium of the arteria hepatica dextra which was in communication with the small bowel. The successful treatment was performed by embolizing the aneurysma. Conclusion The reasons for gastrointestinal bleedings are manifold. This case presents a seldom cause of a gastrointestinal bleeding due to an aneurysma of the hepatic arteria. The successful embolization was performed to ultimately stop the bleeding. PMID:23885918

    AIM: To compare the results of transvaginal cholecystectomy (TVC) and conventional laparoscopic cholecystectomy (CLC) for gallbladder disease. METHODS: We performed a literature search of PubMed, EMBASE, Ovid, Web of Science, Cochrane Library, Google Scholar, MetaRegister of Controlled Trials, Chinese Medical Journal database and Wanfang Data for trials comparing outcomes between TVC and CLC. Data were extracted by two authors. Mean difference (MD), standardized mean difference (SMD), odds ratios and risk rate with 95%CIs were calculated using fixed- or random-effects models. Statistical heterogeneity was evaluated with the χ2 test. The fixed-effects model was used in the absence of statistically significant heterogeneity. The random-effects model was chosen when heterogeneity was found. RESULTS: There were 730 patients in nine controlled clinical trials. No significant difference was found regarding demographic characteristics (P > 0.5), including anesthetic risk score, age, body mass index, and abdominal surgical history between the TVC and CLC groups. Both groups had similar mortality, morbidity, and return to work after surgery. Patients in the TVC group had a lower pain score on postoperative day 1 (SMD: -0.957, 95%CI: -1.488 to -0.426, P < 0.001), needed less postoperative analgesic medication (SMD: -0.574, 95%CI: -0.807 to -0.341, P < 0.001) and stayed for a shorter time in hospital (MD: -1.004 d, 95%CI: -1.779 to 0.228, P = 0.011), but had longer operative time (MD: 17.307 min, 95%CI: 6.789 to 27.826, P = 0.001). TVC had no significant influence on postoperative sexual function and quality of life. Better cosmetic results and satisfaction were achieved in the TVC group. CONCLUSION: TVC is safe and effective for gallbladder disease. However, vaginal injury might occur, and further trials are needed to compare TVC with CLC. PMID:25954114

    Introduction Natural orifice transluminal endoscopic surgery (NOTES) transvaginal cholecystectomy is being intensively studied. A few studies have been recently published evaluating patients’ attitude towards NOTES with its individual accesses. However, the choice of a transvaginal access with its potential influence on sex life and fertility is not restricted entirely to women. The sexual partner would at least give his opinion or decide together with the woman. Aim The aim of the study was to assess the attitude of male sexual partners of potential NOTES transvaginal patients towards the surgical access. Material and methods Hundred males were asked for their opinion in a specially designed instrument. Results The general attitude of male sexual partners of potential NOTES transvaginal cholecystectomy patients is negative. With several possible problems and complications feared by the partners, they would mostly oppose or dissuade against NOTES transvaginal cholecystectomy. The cosmetic benefit seems not to justify undergoing a novelty procedure with potential complications threatening sexual life and procreation. This attitude was especially observed in young, sexually active males with high appreciation of sexual life. Conclusions Both scientific and educational efforts are required to prove safety and efficiency of NOTES transvaginal cholecystectomy beyond question. PMID:23255986

  1. ICG-loaded microbubbles for multimodal billiary imaging in cholecystectomy

    A dual-mode imaging technique has been developed for intraoperative imaging of bile ducts and real-time identification of iatrogenic injuries in cholecystectomy. The technique is based on ultrasound (US) and fluorescence (FL) imaging of a dual-mode microbubble (MB) agent comprising a poly (lactic-co-glycolic acid) (PLGA) shell and a core of Indocyanine Green. During cholecystectomy, a clinical US probe is used to localize the bile duct structure after bolus injection of dual-mode MBs. As the surrounding adipose tissue is removed and the Calot's triangle is exposed, FL imaging is used to identify the MB distribution and to determine the potential bile duct injury. The contrast-enhanced bile duct imaging technique has been demonstrated in both a surgical simulation model and an ex vivo porcine tissue model under two surgical scenarios. The first scenario simulates the correct procedure where the cystic duct is clipped. The second scenario simulates the incorrect procedure where the common bile duct is clipped, leading to consequent bile duct injury. Benchtop experiments in both the phantom and the ex vivo models show that the dual-mode imaging technique is able to identify the potential bile duct injury during cholecystectomy. A phantom system has also been established for future device calibration and surgical training in image-guided cholecystectomy. Further in vivo animal validation tests are necessary before the technique can be implemented in a clinical setting.

    This study had 3 major aims: (1) to ascertain the degree to which helicopter emergency medical services (HEMS) administration of antibiotics (Abx) can streamline the time to Abx in open fracture patients, (2) to determine whether any clinical outcome improvements were associated with HEMS Abx therapy, and (3) to calculate the cost-effectiveness of prehospital HEMS Abx. The design of the study was a prospective, nonrandomized, nonintervention, natural study of timing and clinical outcomes for patients with suspected open extremity fracture. There were 138 scene trauma cases transported by 8 participating HEMS programs from July 2009 to June 2010. The participating HEMS programs were both urban and rural. The diagnosis of an open fracture by the HEMS crews had an accuracy rate of 97.8% (95% confidence interval, 90.8%-98.4%). The time from the incident to Abx was 30 minutes shorter (P = .0001) when Abx were administered by HEMS crews. There was no statistical significance (P = 1.0) regarding the endpoint of infection or nonunion development in HEMS- versus hospital-administered Abx. In conclusion, the administration of Abx by HEMS crews to patients diagnosed with open extremity fractures is feasible, it may decrease the time to Abx by 30 minutes, and the effect magnitude (40.3% relative risk reduction) was promising.

    AIM: To perform a large-scale retrospective comparison of laparoendoscopic single-site cholecystectomy (LESSC) and three-port laparoscopic cholecystectomy (TPLC) in a single institution. METHODS: Data were collected from 366 patients undergoing LESSC between January 2005 and July 2008 and were compared with the data from 355 patients undergoing TPLC between August 2008 and November 2011 in our department. Patients with body mass index greater than 35 kg/m2, a history of major upper abdominal surgery, signs of acute cholecystitis, such as fever, right upper quadrant tenderness with or without Murphy’s sign, elevated white blood cell count, imaging findings suggestive of pericholecystic fluid, gallbladder wall thickening > 4 mm, and gallstones > 3 cm, were excluded to avoid bias. RESULTS: Altogether, 298 LESSC and 315 TPLC patients met the inclusion criteria. The groups were well matched with regard to demographic data. There were no significant differences in terms of postoperative complications (contusion: 19 vs 25 and hematoma at incision: 11 vs 19), hospital stay (mean ± SD, 1.4 ± 0.2 d vs 1.4 ± 0.7 d) and visual analogue pain score (mean ± SD, 8 h after surgery: 2.3 ± 1.4 vs 2.3 ± 1.3 and at day 1: 1.2 ± 0.4 vs 1.3 ± 1.2) between the LESSC and TPLC patients. Four patients required the addition of extra ports and 2 patients were converted to open surgery in the LESSC group, which was not significantly different when compared with TPLC patients converted to laparotomy (2 vs 2). LESSC resulted in a longer operating time (mean ± SD, 54.8 ± 11.0 min vs 33.5 ± 9.0 min), a higher incidence of intraoperative gallbladder perforation (56 vs 6) and higher operating cost (mean ± SD, 1933.7 ± 64.4 USD vs 1874.7 ± 46.2 USD) than TPLC. No significant differences in operating time (mean ± SD, 34.3 ± 6.0 min vs 32.7 ± 8.7 min) and total cost (mean ± SD, 1881.3 ± 32.8 USD vs 1876.2 ± 33.4 USD) were found when the last 100 cases in the two groups were

    Laparoscopic cholecystectomy has become the new gold standard for management of symptomatic gallstones. Prophylactic antibiotics are used in elective surgery by the majority of surgeons, and their role in biliary tract surgery has been well established for a subpopulation of high-risk patients. This consensus has been derived from multiple studies involving biliary tract surgery before and in the era of laparoscopic cholecystectomy. But the use of prophylactic antibiotics in laparoscopic cholecystectomy especially in the low-risk group is now controversial and varied among the surgeons all over the world. To study the role of prophylactic antibiotics in laparoscopic cholecystectomy in different risk groups of patients, a prospective study was conducted in the Department of Surgery of Bankura Sammilani Medical College and Hospital from January 2010 to July 2011. All patients with symptomatic gallstones who underwent elective laparoscopic cholecystectomy during this period are included in this study. One hundred and two patients with symptomatic gallstones were operated on by laparoscopic technique without receiving preoperative antibiotics and studied over a period of 1.5 years. Ages ranged from 11 to 70 years (mean age of 33 years). There were 14 males (13.72 % of the patients) and 88 females (86.27 % of the patients). There was no wound infection (class I) in 99 patients, and class II type of wound infection, i.e., surgical site infection, occurred in three patients (i.e., 2.94 %) out of a total of 102 patients. Swabs were taken for culture and sensitivity; Staphylococcus aureus was found in two patients and Streptococcus viridans in one patient. In all three patients, infection occurred at the umbilical port sites, detected on the 3rd and 4th postoperative days. Antibiotic prophylaxis is not necessary in low-risk patients with symptomatic gallstone disease undergoing elective laparoscopic cholecystectomy to prevent postoperative infection

    Purpose Single incision laparoscopic cholecystectomy (SILC) is generally performed with the use of inverse triangulation. In this study, we performed 3-channel or 4-channel SILC without the use of inverse triangulation. We evaluated the adequacy and feasibility of SILC using our surgical method. Methods We retrospectively reviewed our series of 309 SILCs performed between March 2014 and February 2015. Results Among 309 SILCs, male were 148 and female were 161 patients, mean age was 48.7 ± 15.3 years old and mean body mass index was 24.8 ± 3.8 kg/m2. Forty patients had previously undergone abdominal surgery including 6 cases of upper abdominal surgery. SILC after percutaneous transhepatic gallbladder (GB) drainage was completed in 8.7% of cases. There were 10 cases of emergency SILC. SILC was performed for noncomplicated GB including symptomatic GB stone and polyp in 66.7% of cases, acute cholecystitis in 33.3%. Overall, 96.8% of procedures were successfully completed without additional port. The reason for addition of an extra port or open conversion included technical difficulties due to severe adhesion and bleeding. The mean operating time was 60.7 ± 22.3 minutes. The overall complication rate was 4.8%: 9 patients of wound seroma, 1 case of bile leakage from GB bed, 4 cases of intra-abdominal abscess or fluid collection, and 1 case of incisional hernia were developed. There was no case of common bile duct injury. Conclusion Our surgical method of SILC without the use of inverse triangulation is safe, feasible and effective technique. PMID:26878014

    Laparoscopic cholecystectomy, which was introduced to the arsenal of surgical procedures in the middle of the 1980s, is a common alternative for conventional cholecystectomy. Its primary advantage is less invasive character which entails shorter hospitalization and faster recovery. Nevertheless, the complications of both procedures are comparable and encompass multiple organs and tissues. The paper presents ultrasound presentation of the surgical bed after laparoscopic cholecystectomy and of complications associated with this procedure. In the first week following the surgery, the presence of up to 60 ml of fluid in the removed gallbladder bed should be considered normal in certain patients. The fluid will gradually absorb. In single cases, slight amounts of fluid are detected in the peritoneal cavity, which also should not be alarming. Carbon dioxide absorbs from the peritoneal cavity within two days. Ultrasound assessment of the surgical bed after cholecystectomy is inhibited by hemostatic material left during the surgery. Its presentation may mimic an abscess. In such cases, the decisive examination is magnetic resonance imaging but not computed tomography. On the other hand, rapidly accumulating fluid around the liver is an alarming symptom, particularly when there is inadequate blood supply or when peritoneum irritation symptoms develop. Depending on the suspected cause of the patient's deteriorating condition, it is essential to perform urgent computed tomography angiography, celiac angiography or endoscopic retrograde cholangiopancreatography or magnetic resonance cholangiopancreatography. The character of the fluid collection may be determined by its ultrasound-guided puncture. This procedure allows for aspiration of fluid and placement of a drain. Moreover, transabdominal ultrasound examination after laparoscopic cholecystectomy may contribute to the identification of: dropped stones in the right hypochondriac region, residual fragment of the gallbladder

    Introduction Helicobacter pylori (H.pylori) is associated with gastritis, peptic ulcer, gastric carcinoma and gastric lymphoma. Current literature describes presence of H.pylori in various extra-gastric locations and its association with many diseases. Apart from the conventional location of gastric and duodenal mucosa, H.pylori have been isolated and cultured from gallbladder. Aim Analysis of cholecystectomy specimens to detect H.pylori by means of immunohistochemical staining. Materials and Methods There were a total of 118 cholecystectomy specimens received in the Department of Pathology in three months duration. We have performed immunostaining for H.pylori in 45 consecutive cases of cholecystectomy specimen. Clinical and other investigational information were retrieved from the medical records department. For each case, routine Haematoxylin and Eosin stain was studied. Immunohistochemistry (IHC) was done using purified polyclonal Helicobacter pylori antiserum. Results Majority of the patients had undergone laparoscopic cholecystectomy for the presenting complaint of right hypochondrial pain. Multiple pigmented stones were present in majority (27/45) of them. Immunostain for H.pylori was positive in ten cases. Six of these cases had pigmented gall stones, two had stones not specified and in two of the cases there were no stones. Conclusion Helicobacter pylori is present in gall bladder and is commonly seen in association with stones. A more detailed study of cholecystectomy cases (both neoplastic and non-neoplastic) with serological, culture and molecular data of H.pylori is desirable to study the pathogenesis of cholecystitis, its association with gall stones and other gall bladder disorders.

    Abstract The laparoscopic cholecystectomy (LC) is an important approach of treating acute cholecystitis and the timing of performing this given treatment is associated with clinical outcomes. Although several meta-analyses have been done to investigate the optimal timing of implementing this treatment, the conflicting findings from these meta-analyses still confuse decision-making. And thus, we performed this systematic review to assess discordant meta-analyses and generate conclusive findings to facilitate informed decision-making in clinical context eventually. We electronically searched the PubMed, Cochrane Library, and EMBASE to include meta-analysis comparing early (within 7 days of the onset of symptoms) with delayed LC (at least 1 week after initial conservative treatment) for acute cholecystitis through August 2015. Two independent investigators completed all tasks including scanning and appraising eligibility, abstracting essential information using prespecified extraction form, assessing methodological quality using Oxford Levels of Evidence and Assessment of Multiple Systematic Reviews (AMSTAR) tool, and assessing the reporting quality using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), as well as implementing Jadad algorithm in each step for the whole process. A heterogeneity degree of ≤50% is accepted. Seven eligible meta-analyses were included eventually. Only one was Level I of evidence and remaining studies were Level II of evidence. The AMSTAR scores varied from 8 to 11 with a median of 9. The PRISMA scores varied from 19 to 26. The most heterogeneity level fell into the desired criteria. After implementing Jadad algorithm, 2 meta-analyses with more eligible RCTs were selected based on search strategies and implication of selection. The best available evidence indicated a nonsignificant difference in mortality, bile duct injury, bile leakage, overall complications, and conversion to open surgery, but a significant

    Background: Surgical technique using small-diameter instruments and single-incision laparoscopy are two new options for less invasive laparoscopic cholecystectomy (LC). In this study, we have compared mini-LC (MLC) with single-incision LC (SILC). Materials and Methods: This study is a randomized clinical trial conducted on the patients diagnosed with symptomatic cholelithiasis who underwent LC. Forty patients were randomized to two equal groups of MLC and SILC. They were compared in terms of demographic data, operation time, and surgical complications. Results: Baseline characteristics were similar in two groups. Operation time in MLC was significantly shorter than that in SILC (45.1 ± 69 min vs 63.75 ± 7.57 min, P-value < 0.001). Also, the total length of the wound in SILC group was shorter than that in MLC group (P-value < 0.003). Postoperative pain scores were similar in two groups. Hospital stay was shorter in MLC (1.2 ± 0.6 days vs 1.6 ± 0.8 days, P < 0.021). There was no difference in postoperative complications in two groups. Conclusion: MLC because of less operation time is preferred than SILC. Also, by subjective measures, it was a more comfortable method compared to SILC. PMID:26958049

    Background: Postoperative pain is a major problem following laparoscopic cholecystectomy, and there is no general agreement on the effective method of pain relief. Rectal morphine suppositories are one of the newly released morphine forms. The aim of this study is to compare the impact of suppository morphine with placebo on pain relief after laparoscopic cholecystectomy. Materials and Methods: Seventy patients scheduled for elective laparoscopic cholecystectomy under general anesthesia, were randomly allocated to two groups according to the drug used for postoperative analgesia: Group morphine suppository (MS - 10 mg) just before induction of anesthesia And Group placebo suppository (PS) (the pills were made from cocoa butter, physically similar to the real drug). Pain intensity based on visual analog scale (VAS) and opioid consumption were assessed 30 and 60 min, and 2, 4, 8, 16, and 24 h after arrival of the patient to the recovery room. Results: VAS scores were significantly lower in MS group (from 3.8 ± 1 to 5.3 ± 1.6) compared with PS group (from 4.9 ± 0.9 to 6.7 ± 1) from 30 min after arrival to the recovery room until 16 h postoperatively (P < 0.05). There were no additional analgesic requirements in the first 2 h after the entrance of the patient to the recovery room in MS group. The number of patients requiring pethidine was significantly different between two groups (P < 0.05) in all periods except for 24 h postoperatively. Conclusion: Suppository morphine administration is more effective than placebo to reduce pain and analgesic requirements after laparoscopic cholecystectomy. PMID:27110554

    The purpose of this study was to compare the incidence of deep venous thrombosis (DVT) in patients undergoing uncomplicated laparoscopic cholecystectomy and in whom conversion to laparotomy was required. Using the Duplex Doppler examination, we found higher incidence of DVT in patients who required conversion than in those who did not (47 vs 58%). Prolonged prophylaxis with low-molecular weight heparin should be considered in these patients. PMID:9931805

    Background In traditional laparoscopic cholecistectomy, the cystic duct and artery are commonly closed by metallic clips just before their division. Although the placement of these clips for occluding cystic artery and duct can be considered safe, biliary leaks and bleeding may occur especially by its dislodgement. Aim To report a prospective case-series in total clipless cholecystectomy by means of harmonic shears for closure and division of the artery and cystic duct as well removal of the gallbladder from the liver. Methods Was evaluate a series of 125 patients who underwent laparoscopic cholecystectomy where the sealing and division of cystic artery and duct was carried out only by harmonic shears. The intact extracted gallbladder was submitted to a reverse pressure test for assessment of the technique safety by means of CO2 insuflation. Results The most common indication for surgery was gallstones. The mean operative time was 26 min and all gallbladders were dissected intact from the liver bed. There was no mortality and the overall morbidity rate was 0.8% with no hemorrhage or leaks. The reverse pressure test showed that all specimens support at least 36-mmHg of pressure without leaking. Conclusions The harmonic shears is effective and safe in laparoscopic cholecystectomy as a sole instrument for sealing and division of the artery and cystic duct. The main advantages could be related to the safety and decreased operative time. PMID:25861071

  13. Use of CO2 laser flexible waveguides during laparoscopic cholecystectomy

    Laparoscopic cholecystectomy has revolutionized the management of symptomatic cholelithiasis and cholecystitis. Although electrosurgery devices are used by a majority of surgeons, laser technology is a valued addition to the armamentarium of the skilled laser laparoscopist. A variety of fiberoptic capable wavelengths have been applied successfully during this procedure. Use of the CO2 laser for this purpose has lagged due to difficulties encountered with free-beam and rigid waveguide dissections via the laparoscope. Recent developments in flexible waveguide technology have the potential to expand the role of the CO2 laser for laparoscopic cholecystectomy and other procedures. Twelve laparoscopic cholecystectomies were performed using Luxar (Bothell, WA) flexible microwaveguides of various configurations. In each case, dissection of the gallbladder from the gallbladder bed was accomplished with acceptable speed and hemostasis. There were no complications. Shortcomings include coupling and positioning with an articulated arm and occasional clogging of some waveguide tips with debris. Modifications of this technology are suggested. Flexible waveguides make the CO2 laser a practical alternative for surgical laparoscopy.

    The Authors present a new gasless laparoscopic cholecystectomy method using an abdominal wall elevator with subcutaneous traction ("laparotenser"). Fifty patients between May 1994 and March 1995 were operated by videolaparoscopy using this new gasless method. Twenty of them were operated with Nagai's method while the laparotenser was used in the remaining thirty. The results obtained are similar to those using pneumoperitoneum. It has been observed a global reduction of costs, less postoperative pain, no influence in cardiovascular and metabolic indexes. No complications were reported during the postoperative period but two cases of conversion to laparotomy not related to the method used were needed. Laparoscopic cholecystectomy without pneumoperitoneum using the subcutaneous elevator of the abdominal wall ("laparotenser") has demonstrated that it's possible to operate in a working space similar to that created by the pneumoperitoneum. After an initial period of distrust towards the laparoscopic methods without pneumoperitoneum it has been accepted that gasless methods multiply the indications to minimally invasive surgery in patients with cardiorespiratory problems considered no ideal candidates to laparoscopic cholecystectomy with pneumoperitoneum.

    In this paper and Paper II, we outline a general framework for the thermodynamic description of open chemical reaction networks, with special regard to metabolic networks regulating cellular physiology and biochemical functions. We first introduce closed networks "in a box", whose thermodynamics is subjected to strict physical constraints: the mass-action law, elementarity of processes, and detailed balance. We further digress on the role of solvents and on the seemingly unacknowledged property of network independence of free energy landscapes. We then open the system by assuming that the concentrations of certain substrate species (the chemostats) are fixed, whether because promptly regulated by the environment via contact with reservoirs, or because nearly constant in a time window. As a result, the system is driven out of equilibrium. A rich algebraic and topological structure ensues in the network of internal species: Emergent irreversible cycles are associated with nonvanishing affinities, whose symmetries are dictated by the breakage of conservation laws. These central results are resumed in the relation a + b = sY between the number of fundamental affinities a, that of broken conservation laws b and the number of chemostats sY. We decompose the steady state entropy production rate in terms of fundamental fluxes and affinities in the spirit of Schnakenberg's theory of network thermodynamics, paving the way for the forthcoming treatment of the linear regime, of efficiency and tight coupling, of free energy transduction, and of thermodynamic constraints for network reconstruction.

    An emergency in-flight egress system was installed in a light general aviation airplane. The airplane had no provision for egress on the left side. To avoid a major structural redesign for a mechanical door, an add on 11.2 kg (24.6 lb) pyrotechnic-actuated system was developed to create an opening in the existing structure. The skin of the airplane was explosively severed around the side window, across a central stringer, and down to the floor, creating an opening of approximately 76 by 76 cm. The severed panel was jettisoned at an initial velocity of approximately 13.7 m/sec. System development included a total of 68 explosive severance tests on aluminum material using small samples, small and full scale flat panel aircraft structural mockups, and an actual aircraft fuselage. These tests proved explosive sizing/severance margins, explosive initiation, explosive product containment, and system dynamics. This technology is applicable to any aircraft of similar construction.

    Objective: We aimed to investigate the technical feasibility of single-incision laparoscopic cholecystectomy (SILC) with our new facilitative maneuver and to compare it with the gold standard four-port laparoscopic cholecystectomy (LC). Material and Methods: Operation time, cosmetic score and incisional hernia rates between LC (n=20) and SILC-1 (first 20 consecutive operations with the new technique) and 2 (subsequent 20 operations with the new technique) were compared. Results: The median operation time for LC, SILC-1 and SILC-2 were; 35 min (12–75), 47.5 min (30–70), and 30 min (12–80), respectively (p=0.005). The operation duration was similar in LC and SILC-2 (p=0.277) groups. Wound seroma rate was higher in SILC-1 (45%) and SILC-2 (30%) groups than LC (5%) group (p=0.010). Cosmetic score was similar between all the groups. Hernia rates were 15.8% and 5.3% in the SILC-1 and SILC-2 groups, respectively, while there was no hernia in the LC group. Conclusion: SILC with new facilitating maneuver is comparable with classical four-port laparoscopic cholecystectomy in terms of ease, operation time, reproducibility and safety. Besides these advantages, the single-incision access technique must be optimized to provide comparable wound complication and postoperative hernia rates before being recommended to patients.

    Objective The study aims to investigate whether laparoscopic cholecystectomy (LC) is a cost-effective strategy for managing gallbladder-stone disease compared to the conventional open cholecystectomy(OC) in a Thai setting. Design and Setting Using a societal perspective a cost-utility analysis was employed to measure programme cost and effectiveness of each management strategy. The costs borne by the hospital and patients were collected from Chiang Rai regional hospital while the clinical outcomes were summarised from a published systematic review of international and national literature. Incremental cost per Quality Adjusted Life Year (QALY) derived from a decision tree model. Results The results reveal that at base-case scenario the incremental cost per QALY of moving from OC to LC is 134,000 Baht under government perspective and 89,000 Baht under a societal perspective. However, the probabilities that LC outweighed OC are not greater than 95% until the ceiling ratio reaches 190,000 and 270,000 Baht per QALY using societal and government perspective respectively. Conclusion The economic evaluation results of management options for gallstone disease in Thailand differ from comparable previous studies conducted in developed countries which indicated that LC was a cost-saving strategy. Differences were due mainly to hospital costs of post operative inpatient care and value of lost working time. The LC option would be considered a cost-effective option for Thailand at a threshold of three times per capita gross domestic product recommended by the committee on the Millennium Development Goals.

    Background/Aims Patients undergoing cholecystectomy may have small intestinal bacterial overgrowth (SIBO). We investigated the prevalence and characteristics of SIBO in patients with intestinal symptoms following cholecystectomy. Methods Sixty-two patients following cholecystectomy, 145 with functional gastrointestinal diseases (FGIDs), and 30 healthy controls undergoing hydrogen (H2)-methane (CH4) glucose breath test (GBT) were included in the study. Before performing GBT, all patients were interrogated using bowel symptom questionnaire. The positivity to GBT indicating the presence of SIBO, gas types and bowel symptoms were surveyed. Results Post-cholecystectomy patients more often had SIBO as evidenced by a positive (+) GBT than those with FGID and controls (29/62, 46.8% vs 38/145, 26.2% vs 4/30, 13.3%, respectively; P = 0.010). In the gas types, the GBT (H2) + post-cholecystectomy patients was significantly higher than those in FGIDs patients (P = 0.017). Especially, positivity to fasting GBT (H2) among the GBT (H2)+ post-cholecystectomy patients was high, as diagnosed by elevated fasting H2 level. The GBT+ group had higher symptom scores of significance or tendency in abdominal discomfort, bloating, chest discomfort, early satiety, nausea, and tenesmus than those of the GBT negative group. The status of cholecystectomy was the only significant independent factor for predicting SIBO. Conclusions The SIBO with high levels of baseline H2 might be the important etiologic factor of upper GI symptoms for post-cholecystectomy patients. PMID:26351251

    In their Finnish National Spatial Strategy 2010-2015 the Finland's Ministry of Agriculture and Forestry delineated e.g. that spatial data skills should support citizens everyday activities and facilitate decision-making and participation of citizens. Studies also predict that open data, particularly open spatial data, would create, when fully realizing their potential, a 15% increase into the turnovers of Finnish private sector companies. Finnish libraries have a long tradition of serving at the heart of Finnish information society. However, with the emerging possibilities of educating their users on open spatial data a very few initiatives have been made. The National Survey of Finland opened its data in 2012. Finnish technology university libraries, such as Aalto University Library, are open environments for all citizens, and seem suitable of being the first thriving entities in educating citizens on open geospatial data. There are however many obstacles to overcome, such as lack of knowledge about policies, lack of understanding of geospatial data services and insufficient know-how of GIS software among the personnel. This framework examines the benefits derived from an international collaboration between Purdue University Libraries and Aalto University Library to create local strategies in implementing open spatial data education initiatives in Aalto University Library's context. The results of this international collaboration are explicated for the benefit of the field as a whole.

    2013-10-01

    The primary method by which social scientists describe public opinion about science and technology is to present frequencies from fixed response survey questions and to use multivariate statistical models to predict where different groups stand with regard to perceptions of risk and benefit. Such an approach requires measures of individual preference which can be aligned numerically in an ordinal or, preferably, a continuous manner along an underlying evaluative dimension - generally the standard 5- or 7-point attitude question. The key concern motivating the present paper is that, due to the low salience and "difficult" nature of science for members of the general public, it may not be sensible to require respondents to choose from amongst a small and predefined set of evaluative response categories. Here, we pursue a different methodological approach: the analysis of textual responses to "open-ended" questions, in which respondents are asked to state, in their own words, what they understand by the term "DNA." To this textual data we apply the statistical clustering procedures encoded in the Alceste software package to detect and classify underlying discourse and narrative structures. We then examine the extent to which the classifications, thus derived, can aid our understanding of how the public develop and use "everyday" images of, and talk about, biomedicine to structure their evaluations of emerging technologies.

  6. From "lists of traits" to "open-mindedness": emerging issues in cultural competence education.

    2011-06-01

    The incorporation of "culture" into U.S. biomedicine has been increasing at a rapid pace over the last several decades. Advocates for "cultural competence" point to changing patient demographics and growing health disparities as they call for improved educational efforts that train health providers to care for patients from a variety of backgrounds. Medical anthropologists have long been critical of the approach to "culture" that emerges in cultural competence efforts, identifying an essentialized, static notion of culture that is conflated with racial and ethnic categories and seen to exist primarily among exotic "Others." With this approach, culture can become a "list of traits" associated with various racial and ethnic groups that must be mastered by health providers and applied to patients as necessary. This article uses an ethnographic examination of cultural competence training to highlight recent efforts to develop more nuanced approaches to teaching culture. I argue that much of contemporary cultural competence education has rejected the "list of traits" approach and instead aims to produce a new kind of health provider who is "open-minded," willing to learn about difference, and treats each patient as an individual. This shift, however, can ultimately reinforce behavioral understandings of culture and draw attention away from the social conditions and power differentials that underlie health inequalities.

    Rapid and uniform seed germination and seedling emergence under diverse environmental conditions is a desirable characteristic for crops. Common bean genotypes (Phaseolus vulgaris L.) differ in their low temperature tolerance regarding growth and yield. Cultivars tolerant to low temperature during the germination and emergence stages and carriers of the grain quality standards demanded by consumers are needed for the success of the bean crop. The objectives of this study were (i) to screen the seedling emergence and the phenotypic response of bean germplasm under a range of temperatures in controlled chamber and field conditions to display stress-tolerant genotypes with good agronomic performances and yield potential, and (ii) to compare the emergence of bean seedlings under controlled environment and in open field conditions to assess the efficiency of genebanks standard germination tests for predicting the performance of the seeds in the field. Three trials were conducted with 28 dry bean genotypes in open field and in growth chamber under low, moderate, and warm temperature. Morpho-agronomic data were used to evaluate the phenotypic performance of the different genotypes. Cool temperatures resulted in a reduction of the rate of emergence in the bean genotypes, however, emergence and early growth of bean could be under different genetic control and these processes need further research to be suitably modeled. Nine groups arose from the Principal Component Analysis (PCA) representing variation in emergence time and proportion of emergence in the controlled chamber and in the open field indicating a trend to lower emergence in large and extra-large seeded genotypes. Screening of seedling emergence and phenotypic response of the bean germplasm under a range of temperatures in controlled growth chambers and under field conditions showed several genotypes, as landraces 272, 501, 593, and the cultivar Borlotto, with stress-tolerance at emergence, and high yield

    We present a case of a 59-y-old woman who had undergone cholecystectomy and was subsequently found to have an abscess within the gallbladder fossa. A hepatobiliary scan using (99m)Tc-diisopropyliminodiacetic acid demonstrated the characteristic rim sign, a photopenic defect surrounded by a rim of mildly increased activity immediately adjacent to the gallbladder fossa. The rim sign was thought to be the result of reactive inflammation in the hepatic tissue adjacent to a postoperative abscess within the gallbladder fossa. PMID:26111711

    The gold standard for the management of acute cholecystitis is laparoscopic cholecystectomy. In patients that are not fit for surgery, percutaneous cholecystostomy is the standard treatment. However, the procedure is only a temporary measure for controlling gallbladder symptoms and it is frequently associated with morbidities. Recently, endoscopic options for management of acute cholecystitis have been developed. The approach avoids the need for a percutaneous drain and may allow endoscopic treatment of the gallstone. The aim of this article is to provide an overview on the current status of endoscopic management of acute cholecystitis. PMID:27372290

    The laparoscopic cholecystectomy is now the "gold standard." In around 2 % of cases, there is a need to convert because of the difficult dissection encountered in the Calot's Triangle, a "frozen Calot's triangle." There is no consensus among surgeons about how to tackle this situation. To lower the conversion rate, there is a continuous attempt made to innovate. The authors present their rationale and experience in 100 difficult cases by creating a retro-gallbladder tunnel and encircling the gallbladder by a gauze for maneuvering. PMID:26884672

    Introduction Cholecystectomy is one of the most common general surgical operations performed. Despite level one evidence supporting the role of cholecystectomy in the management of specific gallbladder diseases, practice varies between surgeons and hospitals. It is unknown whether these variations account for the differences in surgical outcomes seen in population-level retrospective data sets. This study aims to investigate surgical outcomes following acute, elective and delayed cholecystectomies in a multicentre, contemporary, prospective, population-based cohort. Methods and analysis UK and Irish hospitals performing cholecystectomies will be recruited utilising trainee-led research collaboratives. Two months of consecutive, adult patient data will be included. The primary outcome measure of all-cause 30-day readmission rate will be used in this study. Thirty-day complication rates, bile leak rate, common bile duct injury, conversion to open surgery, duration of surgery and length of stay will be measured as secondary outcomes. Prospective data on over 8000 procedures is anticipated. Individual hospitals will be surveyed to determine local policies and service provision. Variations in outcomes will be investigated using regression modelling to adjust for confounders. Ethics and dissemination Research ethics approval is not required for this study and has been confirmed by the online National Research Ethics Service (NRES) decision tool. This novel study will investigate how hospital-level surgical provision can affect patient outcomes, using a cross-sectional methodology. The results are essential to inform commissioning groups and implement changes within the National Health Service (NHS). Dissemination of the study protocol is primarily through the trainee-led research collaboratives and the Association of Upper Gastrointestinal Surgeons (AUGIS). Individual centres will have access to their own results and the collective results of the study will be published

    Laparoscopic cholecystectomy is one of the most commonly performed surgical procedures and the laryngeal mask airway (LMA) is the most common supraglottic airway device used by the anesthesiologists to manage airway during general anesthesia. Use of LMA has some advantages when compared to endotracheal intubation, such as quick and ease of placement, a lesser requirement for neuromuscular blockade and a lower incidence of postoperative morbididy. However, the use of the LMA in laparoscopy is controversial, based on a concern about increased risk of regurgitation and pulmonary aspiration. The ability of these devices to provide optimal ventilation during laparoscopic procedures has been also questioned. The most important parameter to secure an adequate ventilation and oxygenation for the LMA under pneumoperitoneum condition is its seal pressure of airway. A good sealing pressure, not only state correct patient ventilation, but it reduces the potential risk of aspiration due to the better seal of airway. In addition, the LMAs incorporating a gastric access, permitting a safe anesthesia based on these commented points. We did a literature search to clarify if the use of LMA in preference to intubation provides inadequate ventilation or increase the risk of aspiration in patients undergoing laparoscopic cholecystectomy. We found evidence stating that LMA with drain channel achieves adequate ventilation for these procedures. Limited evidence was found to consider these devices completely safe against aspiration. However, we observed that the incidence of regurgitation and aspiration associated with the use of the LMA in laparoscopic surgery is very low. PMID:26649155

    Legionnaires' disease (LD) is a systemic infection caused by Legionella species especially colonized in the water systems. Hotels are common locations in which waterwork-associated sporadic or epidemic legionellosis can be detected. The aim of this study was to evaluate a small Legionella outbreak emerged in a recently opened 600-bed hotel in Alanya, a touristic county in Mediterranean part of Turkey. A 66 years old male patient who stayed in this hotel opened on May 15th, 2009, was admitted to our hospital on May 21st, 2009 with the complaints of high fever, headache and diarrhea lasting for three days. Since chest X-ray revealed non-homogenous density increase in left middle and inferior zone, the patient was diagnosed as atypical pneumoniae and LD was confirmed by positive urinary Legionella antigen test (Card test, BinaxNOW®Legionella Urinary Antigen Test; Alere Co, USA) result. Following the identification of the index case, the records of our hospital were reviewed and revealed another case being treated with the diagnosis of community acquired pneumonia who was also the guest of the same hotel. This patient was then diagnosed as LD by positive urinary antigen test. Since new cases were identified during the following days (May 22, 25 and 26) the Antalya County Health Department and hotel management were informed about a cluster of LD. In addition subsequent investigation for environmental surveillance and water sampling were conducted. The LD diagnosis and environmental inspections were performed according to the procedure described in the guideline from "Turkish Ministry of Health Travel-Associated Legionnaires' Disease Control Programme". Five definitive cases and one presumptive case of LD were identified during the outbreak period (May 20-26, 2009). All of the cases were successfully treated (intravenous ciprofloxacin or levofloxacin or clarithromycin), however one patient died due to sudden death during sleep after being discharged.

    Background. Laparoscopic cholecystectomy represents the gold standard approach for treatment of symptomatic gallstones. Surgery-associated complications include bleeding, bile duct injury, and retained stones. Migration of surgical clips after cholecystectomy is a rare complication and may result in gallstone formation "clip cholelithiasis". Case Report. We report a case of a 55-year-old female patient who presented with right upper quadrant pain and severe sepsis having undergone an uncomplicated laparoscopic cholecystectomy 10 years earlier. Computed tomography (CT) imaging revealed hyperdense material in the common bile duct (CBD) compatible with retained calculus. Endoscopic retrograde cholangiopancreatography (ERCP) revealed appearances in keeping with a migrated surgical clip within the CBD. Balloon trawl successfully extracted this, alleviating the patient's jaundice and sepsis. Conclusion. Intraductal clip migration is a rarely encountered complication after laparoscopic cholecystectomy which may lead to choledocholithiasis. Appropriate management requires timely identification and ERCP. PMID:25874138

    The present case is one of gallstone obstructive ileus due to gallstones 3 yr after laparoscopic cholecystectomy. It is interesting because of the sex of the patient, the fact that ileus occurred 3 yr after cholecystectomy and that the localization of the obstruction was an old side-to-side ileoileal anastomosis due to a diverticulectomy following intussusception of Meckels' diverticulum at the age of 3.

    Little attention has been paid to the effectiveness of hypnosis in improving the results of surgery in Iran. One hundred and twenty patients scheduled for laparoscopic cholecystectomy were randomly divided into either control (standard care) or experimental (hypnosis) groups. Prior to surgery and again after surgery, abdominal pain, nausea, and vomiting were assessed. The results suggest that hypnosis could effectively reduce pain after laparoscopic cholecystectomy and significantly reduce hospitalization time. PMID:27267679

    Cases of sudden death due to pulmonary thromboembolism (PTE) following laparoscopic surgery are very rare. The risk factors for PTE include sex, operation duration, age, obesity, and underlying diseases. The development of thromboprophylaxis according to specific risk factors has contributed to the decrease in postoperative mortality. Here, we describe the case of a 50-year-old patient with sudden death due to PTE at 24 hours after laparoscopic cholecystectomy. The origin of the thrombi were bilateral deep vein thromboses in both the lower extremities. No severe risk factors for PTE were detected in the patient, and pneumatic compression devices were used during the surgery for thromboprophylaxis. We believe that the accumulation of minor risk factors may have contributed to the onset of PTE. Hence, a more cautious assessment of the risk factors for PTE prior to surgery is required in such cases. PMID:27356014

    The objective of this study was to achieve an ideal cosmetic result and minimize the access trauma to the abdominal wall. The authors developed a technique to perform cholecystectomies and appendectomies with only one incision in the umbilicus. With the upcoming idea of Natural Orifice Transluminal Endoscopic Surgery (NOTES) in the recent years and noticing the lack of feasibility of the technique for the daily routine beside the technique described by these authors, another development was raising the interest of the surgeons around the world. The single-access surgery through the umbilicus is a technique, that can be used in the daily routine and provides the best cosmetic results. Furthermore, injury of the abdominal wall is located at only one site, which might reduce the rate of trocar hernias and abdominal wall infections. Two 5.5-mm trocars were inserted through an incision at the upper edge of the umbilicus. After perforation of the abdominal wall with a stylet of a 5.5-mm trocar, a curved grasper was inserted, without the use of a trocar, into the abdominal cavity. The use of curved instruments facilitates better triangulation and instrument handling. No gas leakage was observed due to the nonexistence of a trocar. Dissection of the Calot' s triangle or appendix vessels can be done with standard instruments. The curved grasper allows retraction of the gallbladder or appendix. The specimen can be removed through the umbilical incision. The authors present a single-access surgery technique for cholecystectomies and appendectomies using curved instruments. The single-access surgery with parallel inserted curved instruments is feasible. No additional complications are related to this modification other than those known to be associated with laparoscopic surgery. This method offers an almost scarless surgery. Whether other advantages such as less trocar hernias, wound infections, and/or a faster recovery can be achieved, it has not yet to be proven. PMID

    Aim After the revolution in the surgery of gallbladder stones represented by the laparoscopic cholecystectomy, we tried a new technique that further maximize the aesthetic results and that at the same time is of easy learning for young surgeons. Patients and methods From January 2011 to December 2012 we performed at our department 320 cholecystectomy: 27 in laparotomy and 293 in laparoscopy. Of these, 88 underwent to Single Incision Laparoscopic Surgery (SILS), namely the Single Incision Laparoscopic Cholecystectomy (SILC), in recruited patients aged between 19–65 years; 56 patients were females and 32 were males. Results The laparoscopic cholecystectomy with the SILS methodology is a safe technique. Respect to multi-port Laparoscopic Cholecystectomy (LC), we have cosmetic advances. The pain is less in extra-umbilical sites, and the major umbilical pain can be prevented by local anaesthesia. The times are slightly longer, especially at the beginning of training, but after a few of operations it is reduced to about one hour. We didn’t found any other difference in vantage and advantage between the two technics, only a case of postoperative umbilical hernia in SILS. Conclusion We found the SILS a safe and effective technique for the cholecystectomy. PMID:26888698

    Abstract To evaluate the clinical and technical factors affecting the ability of fluorescence cholangiography (FC) using indocyanine green (ICG) to delineate the bile duct anatomy during laparoscopic cholecystectomy (LC). Application of FC during LC began after laparoscopic fluorescence imaging systems became commercially available. In 108 patients undergoing LC, FC was performed by preoperative intravenous injection of ICG (2.5 mg) during dissection of Calot's triangle, and clinical factors affecting the ability of FC to delineate the extrahepatic bile ducts were evaluated. Equipment-related factors associated with bile duct detectability were also assessed among 5 laparoscopic systems and 1 open fluorescence imaging system in ex vivo studies. FC delineated the confluence between the cystic duct and common hepatic duct (CyD–CHD) before and after dissection of Calot's triangle in 80 patients (74%) and 99 patients (92%), respectively. The interval between ICG injection and FC before dissection of Calot's triangle was significantly longer in the 80 patients in whom the CyD–CHD confluence was detected by fluorescence imaging before dissection (median, 90 min; range, 15–165 min) than in the remaining 28 patients in whom the confluence was undetectable (median, 47 min; range, 21–205 min; P < 0.01). The signal contrast on the fluorescence images of the bile duct samples was significantly different among the laparoscopic imaging systems and tended to decrease more steeply than those of the open imaging system as the target-laparoscope distance increased and porcine tissues covering the samples became thicker. FC is a simple navigation tool for obtaining a biliary roadmap to reach the “critical view of safety” during LC. Key factors for better bile duct identification by FC are administration of ICG as far in advance as possible before surgery, sufficient extension of connective tissues around the bile ducts, and placement of the tip of

    Introduction Conventional laparoscopic procedures have been used for splenic diseases and concomitant gallbladder stones, frequently in patients with hereditary spherocytosis since 1990’s. The aim of this study is to evaluate the feasibility of single-site surgery with conventional instruments in combined procedures. Presentation of case series Six consecutive patients who scheduled for combined cholecystectomy and splenectomy because of hereditary spherocytosis or autoimmune hemolytic anemia were included this study. Both procedures were performed via trans-umbilical single-site multiport approach using conventional instruments. All procedures completed successfully without conversion to open surgery or conventional laparoscopic surgery. An additional trocar was required for only one patient. The mean operation time was 190 min (150–275 min). The mean blood loss was 185 ml (70–300 ml). Median postoperative hospital stay was two days. No perioperative mortality or major complications occurred in our series. Recurrent anemia, hernia formation or wound infection was not observed during the follow-up period. Discussion Nowadays, publications are arising about laparoscopic or single site surgery for combined diseases. Surgery for combined diseases has some difficulties owing to the placement of organs and position of the patient during laparoscopic surgery. Single site laparoscopic surgery has been proposed to have better cosmetic outcome, less postoperative pain, greater patient satisfaction and faster recovery compared to standard laparoscopy. Conclusion We consider that single-site multiport laparoscopic approach for combined splenectomy and cholecystectomy is a safe and feasible technique, after gaining enough experience on single site surgery.

    2014-01-01

    Background: As part of the EuroDRG project, researchers from eleven countries (i.e. Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Sweden, and Spain) compared how their Diagnosis-Related Groups (DRG) systems deal with cholecystectomy patients. The study aims to assist surgeons and national authorities to optimize their DRG systems. Methods: National or regional databases were used to identify hospital cases with a procedure of cholecystectomy. DRG classification algorithms and indicators of resource consumption were compared for those DRGs that individually contained at least 1% of cases. Six standardised case vignettes were defined, and quasi prices according to national DRG-based hospital payment systems were ascertained and compared to an index case. Results: European DRG systems vary widely: they classify cholecystectomy patients according to different sets of variables into diverging numbers of DRGs (between two DRGs in Austria and Poland to nine DRGs in England). The most complex DRG is valued at four times more resource intensive than the index case in Ireland but only 1.3 times more resource intensive than the index case in Austria. Conclusion: Large variations in the classification of cholecystectomy patients raise concerns whether all systems rely on the most appropriate classification variables. Surgeons, hospital managers and national DRG authorities should consider how other countries’ DRG systems classify cholecystectomy patients in order to optimize their DRG systems and to ensure fair and appropriate reimbursement.

    Background. The role of early laparoscopic cholecystectomy for acute cholecystitis with cholelithiasis is not yet established. The aim of our prospective randomized study was to evaluate the safety and feasibility of early LC for acute cholecystitis and to compare the results with delayed LC. Methods. Between March 2007 to December 2008, 50 patients with diagnosis of acute cholecystitis were assigned randomly to early group, n = 25 (LC within 24 hrs of admission), and delayed group, n = 25 (initial conservative treatment followed by delayed LC, 6-8 weeks later). Results. We found in our study that the conversion rate in early LC and delayed LC was 16% and 8%, respectively, Operation time for early LC was 69.4 min versus 66.4 min for delayed LC, postoperative complications for early LC were 24% versus 8% for delayed LC, and blood loss was 159.6 mL early group versus 146.8 mL for delayed group. However early LC had significantly shorter hospital stay (4.1 days versus 8.6 days). Conclusions. Early LC for acute cholecystitis with cholelithiasis is safe and feasible, offering the additional benefit of shorter hospital stay. It should be offered to the patients with acute cholecystitis, provided that the surgery is performed within 96 hrs of acute symptoms by an experienced surgeon. PMID:25729775

    We encapsulate indocyanine green (ICG) in poly[(D,L-lactide-co-glycolide)-co-PEG] diblock (PLGA-PEG) microballoons for real-time fluorescence and hyperspectral imaging of biliary anatomy. ICG-loaded microballoons show superior fluorescence characteristics and slower degradation in comparison with pure ICG. The use of ICG-loaded microballoons in biliary imaging is demonstrated in both biliary-simulating phantoms and an ex vivo tissue model. The biliary-simulating phantoms are prepared by embedding ICG-loaded microballoons in agar gel and imaged by a fluorescence imaging module in a Da Vinci surgical robot. The ex vivo model consists of liver, gallbladder, common bile duct, and part of the duodenum freshly dissected from a domestic swine. After ICG-loaded microballoons are injected into the gallbladder, the biliary structure is imaged by both hyperspectral and fluorescence imaging modalities. Advanced spectral analysis and image processing algorithms are developed to classify the tissue types and identify the biliary anatomy. While fluorescence imaging provides dynamic information of movement and flow in the surgical region of interest, data from hyperspectral imaging allow for rapid identification of the bile duct and safe exclusion of any contaminant fluorescence from tissue not part of the biliary anatomy. Our experiments demonstrate the technical feasibility of using ICG-loaded microballoons for biliary imaging in cholecystectomy.

    Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data. PMID:25437581

    We present a case on abdominal wall abscess from spilled stones post-cholecystectomy and describe laparoscopic drainage as our choice of management. Mr M is a 75-year-old male who presented on multiple occasions to the hospital with right upper quadrant pain and fever post-laparoscopic cholecystectomy. He also required multiple courses of antibiotics. Subsequent computed tomography and magnetic resonance imaging scan confirmed a number of retained stone with signs of chronic inflammation. Hence, 6 months after his initial laparoscopic cholecystectomy, he proceeded to an exploratory laparoscopy. We found an abscess cavity measuring 3 × 4 cm over the anterior abdominal wall. The cavity was de-roofed, drained and washed out. The tissue culture grew Klebsiella pneumoniae. Laparoscopic approach is optimal as the abscess cavity can be clearly identified, stones visualized and removed under direct vision. Patient does not require a laparotomy. PMID:26183574

    Because unsubstantiated beliefs link hysterectomy and cholecystectomy with bowel function, this study examined all the women who had had these operations in a defined population (79 and 37 respectively, out of 1058) with respect to bowel habits, irritable bowel syndrome symptoms, and whole gut transit time calculated from records of three defecations. Compared with unoperated controls, women after hysterectomy were more likely to consider themselves constipated; they also strained more and admitted more often to bloating and feelings of incomplete evacuation. Their stools tended to be lumpier and, in women over 50 years, transit time was longer. When women treated by cholecystectomy were compared with women having newly discovered, asymptomatic gall stones, they more often described defecation as urgent but had no other detectable differences. In conclusion symptomatic constipation is frequent in women after hysterectomy; after cholecystectomy, bowel habit is not consistently changed but the rectum seems to be more irritable. PMID:8174964

  19. Pancreatitis of biliary origin, optimal timing of cholecystectomy (PONCHO trial): study protocol for a randomized controlled trial

    PubMed Central

    2012-01-01

    Background After an initial attack of biliary pancreatitis, cholecystectomy minimizes the risk of recurrent biliary pancreatitis and other gallstone-related complications. Guidelines advocate performing cholecystectomy within 2 to 4 weeks after discharge for mild biliary pancreatitis. During this waiting period, the patient is at risk of recurrent biliary events. In current clinical practice, surgeons usually postpone cholecystectomy for 6 weeks due to a perceived risk of a more difficult dissection in the early days following pancreatitis and for logistical reasons. We hypothesize that early laparoscopic cholecystectomy minimizes the risk of recurrent biliary pancreatitis or other complications of gallstone disease in patients with mild biliary pancreatitis without increasing the difficulty of dissection and the surgical complication rate compared with interval laparoscopic cholecystectomy. Methods/Design PONCHO is a randomized controlled, parallel-group, assessor-blinded, superiority multicenter trial. Patients are randomly allocated to undergo early laparoscopic cholecystectomy, within 72 hours after randomization, or interval laparoscopic cholecystectomy, 25 to 30 days after randomization. During a 30-month period, 266 patients will be enrolled from 18 hospitals of the Dutch Pancreatitis Study Group. The primary endpoint is a composite endpoint of mortality and acute re-admissions for biliary events (that is, recurrent biliary pancreatitis, acute cholecystitis, symptomatic/obstructive choledocholithiasis requiring endoscopic retrograde cholangiopancreaticography including cholangitis (with/without endoscopic sphincterotomy), and uncomplicated biliary colics) occurring within 6 months following randomization. Secondary endpoints include the individual endpoints of the composite endpoint, surgical and other complications, technical difficulty of cholecystectomy and costs.

    Background: Both magnesium and clonidine are known to inhibit catecholamine and vasopressin release and attenuate hemodynamic response to pneumoperitoneum. This randomized, double blinded, placebo controlled study has been designed to assess which agent attenuates hemodynamic stress response to pneumoperitoneum better. Materials and Methods: 120 patients undergoing elective laparoscopic cholecystectomy were randomized into 4 groups of 30 each. Group K patients received 50 ml normal saline over a period of 15 min after induction and before pneumoperitoneum, group M patients received 50 mg/kg of magnesium sulfate in normal saline (total volume 50 ml) over same time duration. Similarly group C1 patients received 1 μg/kg clonidine and group C2 1.5 μg/kg clonidine respectively in normal saline (total volume 50 ml). Blood pressure and heart rate were recorded before induction (baseline value), at the end of infusions and every 5 min after pneumoperitoneum. Statistical Analysis: Paired t test was used for intra-group comparison and ANOVA for inter-group comparison. Results: Systolic blood pressure was significantly higher in control group as compared to all other groups during pneumoperitoneum. On comparing patients in group M and group C1, no significant difference in systolic BP was found at any time interval. Patients in group C2 showed best control of systolic BP. As compared to group M and group C1, BP was significantly lower at 10, 30 and 40 min post pneumoperitoneum. No significant episodes of hypotension were found in any of the groups. Extubation time and time to response to verbal command like eye opening was significantly longer in group M as compared to other groups. Conclusion: Administration of magnesium sulfate or clonidine attenuates hemodynamic response to pneumoperitoneum. Although magnesium sulfate 50 mg/kg produces hemodynamic stability comparable to clonidine 1 μg/kg, clonidine in doses of 1.5μg/kg blunts the hemodynamic response to

    OBJECTIVES: There is little data on the natural history of asymptomatic bile duct stones and hence there is uncertainty on the management of asymptomatic bile duct stones discovered incidentally at the time of laparoscopic cholecystectomy. We retrospectively reviewed a group of patients who had previously underwent laparoscopic cholecystectomy, but who did not have a pre-operative suspicion of intra-ductal stones, to determine if any biliary complications had subsequently developed. A group of patients who had no pre-operative suspicion of intra-ductal stones, but routinely underwent intraoperative cholangiogram (IOC) at time of cholecystectomy, served as the control group. METHODS: A telephone questionnaire was completed by each patient's family practitioner in 59 of 79 (75%) patients who underwent laparoscopic cholecystectomy. In the remaining 20 patients additional information was obtained from hospital records and from the central services agency (CSA). These patients had no pre-operative suspicion of bile duct stones and therefore did not undergo an IOC or ERCP. The control group (73 patients) had no pre-operative suspicion of bile duct stones but had a routine IOC performed to define the biliary anatomy. RESULTS: 59 patients were followed up for an average of 57 months (range 30-78 months) after laparoscopic cholecystectomy. None of these patients developed pancreatitis, jaundice, deranged liver function tests (LFT's), or required ERCP or other biliary intervention. In the additional 20 patients where no information was available from the family practitioner, 11 patients had follow up appointments with no documentation of biliary complications or abnormal LFT's. 19 of 20 patients were traceable through the CSA and were all alive. Only 1 patient was untraceable and therefore unknown if biliary complications had developed. In the control group, 4 of 73 (6%) patients had intraductal stones detected and extracted. Thus the prevalence of asymptomatic bile duct

    Sevoflurane is a "new" volatile inhaled anaesthetic that is currently undergoing phase III clinical trial in Europe and the United States. Owing to the low blood solubility, rapid induction of anaesthesia and emergence from anaesthesia would be expected. In this study, we compared emergence times and haemodynamics in patients receiving either sevoflurane or isoflurane. Furthermore, all adverse effects were recorded and the relationship to the drug administered was rated. METHODS. Fifty ASA physical status I and II patients were studied in an open, prospective, randomised clinical trial. Anaesthesia was induced with fentanyl, thiopentone, and vecuronium for facilitating endotracheal intubation and maintained with sevoflurane or isoflurane, 60% nitrous oxide (N2O) in oxygen (O2), and additional doses of fentanyl (1-2 micrograms/kg.h). The electrocardiogram, blood pressure (non-invasive), O2 saturation, temperature, and end-tidal concentrations of sevoflurane or isoflurane, N2O, and carbon dioxide were monitored continuously. At the end of surgery, administration of sevoflurane or isoflurane and N2O was discontinued without tapering and emergence times were recorded. All adverse events that occurred until the 3rd postoperative day were recorded and the relationship to the inhaled anaesthetic was rated as "none", "unlikely", "possible", "probable", or "highly probable". RESULTS. With the exception of gender, the two patient groups were comparable (Tables 1 and 2). Due to the higher MAC value, mean end-tidal concentrations were higher for sevoflurane (0.82% vs. 0.59% for isoflurane). The duration of anaesthetic exposure was 1.3 MAC h (calculation with FIO2 = 1.0 MAC value) and 3.1 MAC h (calculation with FIO2 = 0.4 in N2O MAC value), respectively, for both inhaled anaesthetics. Pulmonary elimination was faster (Fig. 1) and emergence time shorter (7 min vs. 11.5 min, Table 3) with sevoflurane. There was no difference in the time courses of heart rate and mean arterial

    Introduction Open access (OA) medical publishing is growing rapidly. While subscription-based publishing does not charge the author, OA does. This opens the door for “predatory” publishers who take authors’ money but provide no substantial peer review or indexing to truly disseminate research findings. Discriminating between predatory and legitimate OA publishers is difficult. Methods We searched a number of library indexing databases that were available to us through the University of California, Irvine Libraries for journals in the field of emergency medicine (EM). Using criteria from Jeffrey Beall, University of Colorado librarian and an expert on predatory publishing, and the Research Committee of the International Federation for EM, we categorized EM journals as legitimate or likely predatory. Results We identified 150 journal titles related to EM from all sources, 55 of which met our criteria for OA (37%, the rest subscription based). Of these 55, 25 (45%) were likely to be predatory. We present lists of clearly legitimate OA journals, and, conversely, likely predatory ones. We present criteria a researcher can use to discriminate between the two. We present the indexing profiles of legitimate EM OA journals, to inform the researcher about degree of dissemination of research findings by journal. Conclusion OA journals are proliferating rapidly. About half in EM are legitimate. The rest take substantial money from unsuspecting, usually junior, researchers and provide no value for true dissemination of findings. Researchers should be educated and aware of scam journals.

    The turbulent structures caused by vegetation patch in open channel flows are generally poorly simulated in common turbulent models. Understanding the turbulent structures is essential to investigate important hydrodynamic processes taking place in aquatic ecosystems and fluvial environments. A Large-eddy simulation model is here developed to investigate the flow in a rectangular open channel partially blocked with an artificial emergent vegetation patch. We focus on the effects of turbulent structures on the momentum transfer across the outer line of vegetation region. The calculated results compared well with laboratory measurements. The spatial evolution of turbulent motions was analyzed, and the lengths of the vortices corresponding to the dominant frequency at different locations in the fully developed zone were investigated using a method of spectral analysis based on the model results. A phenomenological model was proposed for the evolution process in the vegetation flow, which divided the entire flow region into four zones: the initial flow zone, the diverging flow zone, the developing zone and the fully developed zone. Vortices at the inner side of the vegetation patch were mainly produced by the wake behind the vegetation element. Vortices in other locations were caused by the vegetation patch, which corresponded exactly to the turbulent structures owing to the interaction between flow and vegetation at the edge of the patch.

    Abstract This study compared virtual reality (VR) training with low cost-blended learning (BL) in a structured training program. Training of laparoscopic skills outside the operating room is mandatory to reduce operative times and risks. Laparoscopy-naïve medical students were randomized in 2 groups stratified for sex. The BL group (n = 42) used E-learning for laparoscopic cholecystectomy (LC) and practiced basic skills with box trainers. The VR group (n = 42) trained basic skills and LC on the LAP Mentor II (Simbionix, Cleveland, OH). Each group trained 3 × 4 hours followed by a knowledge test concerning LC. Blinded raters assessed the operative performance of cadaveric porcine LC using the Objective Structured Assessment of Technical Skills (OSATS). The LC was discontinued when it was not completed within 80 min. Students evaluated their training modality with questionnaires. The VR group completed the LC significantly faster and more often within 80 min than BL (45% v 21%, P = .02). The BL group scored higher than the VR group in the knowledge test (13.3 ± 1.3 vs 11.0 ± 1.7, P < 0.001). Both groups showed equal operative performance of LC in the OSATS score (49.4 ± 10.5 vs 49.7 ± 12.0, P = 0.90). Students generally liked training and felt well prepared for assisting in laparoscopic surgery. The efficiency of the training was judged higher by the VR group than by the BL group. VR and BL can both be applied for training the basics of LC. Multimodality training programs should be developed that combine the advantages of both approaches. PMID:25997044

    AIM: To assess the safety of single-incision laparoscopic cholecystectomy (SILC) for acute cholecystitis. METHODS: All patients who underwent SILC at Sano Hospital (Kobe, Japan) between January 2010 and December 2014 were included in this retrospective study. Clinical data related to patient characteristics and surgical outcomes were collected from medical records. The parameters for assessing the safety of the procedure included operative time, volume of blood loss, achievement of the critical view of safety, use of additional trocars, conversion to laparotomy, intraoperative and postoperative complications, and duration of postoperative hospital stay. Patient backgrounds were statistically compared between those with and without conversion to laparotomy. RESULTS: A total of 100 patients underwent SILC for acute cholecystitis during the period. Preoperative endoscopic treatment was performed for suspected choledocholithiasis in 41 patients (41%). The mean time from onset of acute cholecystitis was 7.7 d. According to the Updated Tokyo Guidelines (TG13) for the severity of cholecystitis, 86 and 14 patients had grade I and grade II acute cholecystitis, respectively. The mean operative time was 87.4 min. The mean estimated blood loss was 80.6 mL. The critical view of safety was obtained in 89 patients (89%). Conversion laparotomy was performed in 12 patients (12%). Postoperative complications of Clavien-Dindo grade III or greater were observed in 4 patients (4%). The mean duration of postoperative hospital stay was 5.7 d. Patients converted from SILC to laparotomy tended to have higher days after onset. CONCLUSION: SILC is feasible for acute cholecystitis; in addition, early surgical intervention may reduce the risk of laparotomy conversion. PMID:26722614

    The increased throughput and decreased cost of next-generation sequencing (NGS) have shifted the bottleneck genomic research from sequencing to annotation, analysis and accessibility. This is particularly challenging for research communities working on organisms that lack the basic infrastructure of a sequenced genome, or an efficient way to utilize whatever sequence data may be available. Here we present a new database, the Assembled Searchable Giant Arthropod Read Database (ASGARD). This database is a repository and search engine for transcriptomic data from arthropods that are of high interest to multiple research communities but currently lack sequenced genomes. We demonstrate the functionality and utility of ASGARD using de novo assembled transcriptomes from the milkweed bug Oncopeltus fasciatus, the cricket Gryllus bimaculatus and the amphipod crustacean Parhyale hawaiensis. We have annotated these transcriptomes to assign putative orthology, coding region determination, protein domain identification and Gene Ontology (GO) term annotation to all possible assembly products. ASGARD allows users to search all assemblies by orthology annotation, GO term annotation or Basic Local Alignment Search Tool. User-friendly features of ASGARD include search term auto-completion suggestions based on database content, the ability to download assembly product sequences in FASTA format, direct links to NCBI data for predicted orthologs and graphical representation of the location of protein domains and matches to similar sequences from the NCBI non-redundant database. ASGARD will be a useful repository for transcriptome data from future NGS studies on these and other emerging model arthropods, regardless of sequencing platform, assembly or annotation status. This database thus provides easy, one-stop access to multi-species annotated transcriptome information. We anticipate that this database will be useful for members of multiple research communities, including developmental

    Objective The aim of the study was to evaluate the inflammatory response to surgical trauma in minilaparotomy cholecystectomy (MC) compared to laparoscopic cholecystectomy (LC). Assessment of inflammatory response to surgical trauma in MC has not been addressed properly. Therefore, we investigated five interleukins (IL) and C-reactive protein (CRP) in MC versus LC group in a prospective randomised trial. Methods Initially, 106 patients with non-complicated symptomatic gallstone disease were randomised into MC (n = 56) or LC (n = 50) groups. Plasma levels of five interleukins (IL-1β, IL-1ra, IL-6, IL-8, IL-10) and hs-CRP were measured at three time points; before operation (PRE), immediately after operation (POP1) and six hours after operation (POP2). The primary end-point of the study was to compare the plasma levels of five interleukins and CRP in LC versus MC group. Results The demographic variables and the surgical data were similar in the study groups. The patients in the MC group had higher elevation of the CRP mean values post-operatively (p = 0.01). However, the patients in the MC group had higher elevation of the IL-1ra mean values post-operatively, the mean pre-/post-operative IL-1ra values being 299/614 pg/ml in the MC group versus 379/439 pg/ml in the LC group (p = 0.003). There was no statistical significance in IL-6 mean values between the MC and LC groups pre- and post-operatively (POP1). However, the patients in the MC group had higher IL-6 mean values six hours post-operatively (POP2), the mean IL-6 values being 27.6 pg/ml in the MC group versus 14.8 pg/ml in the LC group (p = 0.037). In addition, the patients in the MC group had higher elevation of the IL-6 mean values post-operatively, the mean pre-/post-operative IL-6 values being 4.1/27.6 pg/ml in the MC group versus 3.8/14.8 pg/ml in the LC group (p = 0.04). There was no statistical significance in IL-8, IL-10, and IL-1β mean values between the MC and LC

    Although cholecystectomy has been reported to be associated with increased risk of developing hepatocellular carcinoma (HCC), the association between cholecystectomy and prognosis of HCC patients underwent curative resection has never been examined. Through retrospective analysis of the data of 3933 patients underwent curative resection for HCC, we found that cholecystectomy was an independent prognostic factor for recurrence-free survival (RFS) of patients at early stage (BCLC stage 0/A) (p = 0.020, HR: 1.29, 95% CI: 1.04–1.59), and the 1-, 3-, 5-year RFS rates for patients at early stage were significantly worse in cholecystectomy group than in non-cholecystectomy group (80.5%, 61.8%, 52.0% vs 88.2%, 68.8%, 56.8%, p = 0.033). The early recurrence rate of cholecystectomy group was significantly higher than that of non-cholecystectomy group for patients at early stage (59/47 vs 236/333, p = 0.007), but not for patients at advanced stage (BCLC stage C) (p = 0.194). Multivariate analyses showed that cholecystectomy was an independent risk factor for early recurrence (p = 0.005, HR: 1.52, 95% CI: 1.13–2.03) of early stage HCC, but not for late recurrence (p = 0.959). In conclusion, cholecystectomy is an independent predictor for early recurrence and is associated with poorer RFS of early stage HCC. Removal of normal gallbladder during HCC resection may be avoided for early stage patients. PMID:27320390

    The number of breast reconstruction procedures has been increasing in recent years. One of the suggested treatment methods is breast reconstruction with a pedicled skin and muscle TRAM flap (transverse rectus abdominis muscle - TRAM). Surgical incisions performed during a cholecystectomy procedure may be located in the areas significant for flap survival. The aim of this paper is to present anatomical changes in abdominal walls secondary to pedicled skin and muscle (TRAM) flap breast reconstruction, which influence the planned access in cholecystectomy procedures. The authors present 2 cases of cholecystectomy performed due to cholelithiasis in female patients with a history of TRAM flap breast reconstruction procedures. The first patient underwent a traditional method of surgery 14 days after the reconstruction due to acute cholecystitis. The second patient underwent a laparoscopy due to cholelithiasis 7 years after the TRAM procedure. In both cases an abdominal ultrasound scan was performed prior to the operation, and surgical access was determined following consultation with a plastic surgeon. The patient who had undergone traditional cholecystectomy developed an infection of the postoperative wound. The wound was treated with antibiotics, vacuum therapy and skin grafting. After 7 weeks complete postoperative wound healing and correct healing of the TRAM flap were achieved. The patient who had undergone laparoscopy was discharged home on the second postoperative day without any complications. In order to plan a safe surgical access, it is necessary to know the changes in the anatomy of abdominal walls following a pedicled TRAM flap breast reconstruction procedure. PMID:25337177

    The aim of this randomized, double-blind clinical trial was to elucidate the impact of general anesthesia alone (GA) or supplemented with epidural anesthesia (EpiGA) on surgical stress response during laparoscopic cholecystectomy, using stress hormones, glucose, and C-reactive protein (CRP), as potential markers. Sixty-two patients scheduled to undergo elective laparoscopic cholecystectomy were randomly assigned into two groups to receive either GA or EpiGA. Stress hormones [cortisol (COR), human growth hormone (hGH), prolactine (PRL)], glucose, and CRP were determined 1 day before surgery, intraoperatively, and upon first postoperative day (POD1). Plasma COR, hGH, PRL, and glucose levels were maximized intraoperatively in GA and EpiGA groups and reverted almost to baseline on POD1. Significant between-group differences were detected for COR and glucose either intraoperatively or postoperatively, but this was not the case for hGH. PRL was elevated in GA group only intraoperatively. Although, CRP was minimally affected intraoperatively, a notable augmentation on POD1, comparable in both groups, was recorded. These results indicate that hormonal and metabolic stress response is slightly modulated by the use of epidural block supplemented by general anesthesia, in patients undergoing laparoscopic cholecystectomy cholecystectomy. Nevertheless, inflammatory reaction as assessed by CRP seems to be unaffected by the anesthesia regimen. PMID:26882921

    Myotonic dystrophy (MD) is rare disease that offers challenges to anesthesiologists. We report a case of adult patient with myotonic dystrophy who underwent laparoscopic cholecystectomy. A 48-year-old male patient, known case of MD, was presented for laparoscopic cholecystectomy. Physical examination revealed, young man, calm, quite, cooperative, not in pain or distress with frontal baldness, temporal bone recession, elongated face, mild degree of ptosis and swan neck. Under complete aseptic conditions, thoracic epidural T6-7 with catheter insertion was performed while the patient was placed on left lateral side. Plain bupivacaine 0.5% 7cc was injected through the catheter. Level of analgesia tested with ice reached up to T4. Intravenous sedation was achieved with midazolam 2 mg and ketamine 50 mg. The patient was comfortably lying supine on warm heated mattress, except of bilateral shoulder pains which was relieved with midazolam and ketamine. In conclusion, regional anesthesia, spinal or epidural, is preferable in MD patients. Shoulder pains is the main intraoperative problem encountered in our patient. Therefore, studies are needed for treating shoulder pain. To the best of our knowledge, this is the first case report in a patient with MD who underwent laparoscopic cholecystectomy under thoracic epidural analgesia. Myotonic dystrophy (M) is rare disease and represents challenges to anesthesiologists. We report a case of adult patient with myotonic dystrophy who underwent laparoscopic cholecystectomy.

    Laparoscopic techniques, have rapidly increased in popularity because of its various benefits. They are widely used in day-case surgical operations and are extensively published. However, postoperative nausea vomiting (PONV) is a commonly observed phenomenon after laparoscopic procedures. Its occurrence may increase depending on the anesthetic techniques used. Despite the fact that the use of propofol and the new low solubility inhalation anesthetics, lead to faster induction and recovery, their effects on PONV is not sufficiently known. Therefore, the aim of this study is to compare the effects of various anesthetic drugs on recovery characteristics and PONV. Following informed consent, 300 ASA I-III patients scheduled for laparoscopic cholecystectomy were investigated. Anesthesia was induced by 1.5 microgkg(-1) fentanyl, 0.03 mgkg(-1) midazolam, 1.5 mgkg(-1) propofol and 0.01 mgkg(-1) vecuronium for all patients. Anesthesia was maintained with desflurane in group D (n = 100), sevoflurane in group S (n = 100) and propofol infusion in group P (n = 100), beside 50% N20/O2 ventilation. All patients were given 4 mg ondansetron and 8 mg dexamethazone iv for preventing PONV, ten minutes before the end of surgery. At the end of the operation, times for extubation, eye opening, orientation, sitting and walking, and the need of ondansetrone in post anesthetic care unit, were recorded. Also, PONV was observed and recorded as early period (first 4 hours) and late period (4-24 hours). Extubation and eye opening times were meaningfully lower in group D. However, no significant differences were observed in orientation, sitting and walking times and PONV among the three groups. All patients who had PONV were women. A correlation was found between PONV and body weight. Even though there were no statistically significant differences among the groups regarding PONV, the number of patients who had PONV in group P was lower. Early recovery time was shortest in group D, while delayed

    Background Bile leak is a common and serious complication of cholecystectomy with endotherapy being an established method of treatment. This retrospective study presents the 11-year experience of a referral center in endoscopic management of post-cholecystectomy bile leaks. Methods During the period between January 2000 and December 2010, records of patients who had undergone endoscopic retrograde cholangiopancreatography (ERCP) for suspected post-cholecystectomy bile leaks were reviewed for evidence of clinical presentation of bile leaks, cholangiographic findings, type of endoscopic intervention, procedural complications and post-procedure follow-up. Results Seventy-one patients with suspected post-cholecystectomy bile leak were referred for ERCP. Common bile duct (CBD) cannulation was successful in 70 patients (98.59%). Complete transection of CBD was diagnosed in 4 patients; they were treated with surgery. A leak from the cystic duct stump was demonstrated in 49 patients (74.24%), from the ducts of Luschka in 4 (6.06%), from the gallbladder bed in 2 (3.03%), from the CBD in 7 (10.61%) and from the common hepatic duct (CHD) in 4 patients (6.06%). Endoscopic sphincterotomy (ES) plus endoprosthesis was performed in 64 patients (96.97%). A 12-year-old girl with a leak from cystic duct stump was successfully treated with stenting without ES and one patient with leak from gallbladder bed underwent only ES. Endoscopic intervention failed to treat a leak from CHD in one patient. During the follow-up, three patients developed bile duct stricture. Two were treated endoscopically and one with hepaticojejunostomy. Conclusions ES plus large-bore straight plastic biliary stent placement is a safe and effective intervention in post-cholecystectomy bile leaks. PMID:24713781

    Purpose Cholecystectomy in patients with an intact gallbladder after endoscopic removal of stones from the common bile duct (CBD) remains controversial. We conducted a case-control study to determine the risk of recurrent CBD stones and the benefit of cholecystectomy for prevention of recurrence after endoscopic removal of stones from the CBD in Korean patients. Materials and Methods A total of 317 patients who underwent endoscopic CBD stone extraction between 2006 and 2012 were included. Possible risk factors for the recurrence of CBD stones including previous cholecystectomy history, bile duct diameter, stone size, number of stones, stone composition, and the presence of a periampullary diverticulum were analyzed. Results The mean duration of follow-up after CBD stone extraction was 25.4±22.0 months. A CBD diameter of 15 mm or larger [odds ratio (OR), 1.930; 95% confidence interval (CI), 1.098 to 3.391; p=0.022] and the presence of a periampullary diverticulum (OR, 1.859; 95% CI, 1.014 to 3.408; p=0.045) were independent predictive factors for CBD stone recurrence. Seventeen patients (26.6%) in the recurrence group underwent elective cholecystectomy soon after endoscopic extraction of CBD stones, compared to 88 (34.8%) in the non-recurrence group; the difference was not statistically significant (p=0.212). Conclusion A CBD diameter of 15 mm or larger and the presence of a periampullary diverticulum were found to be potential predictive factors for recurrence after endoscopic extraction of CBD stones. Elective cholecystectomy after clearance of CBD stones did not reduce the incidence of recurrent CBD stones in Korean patients. PMID:26632393

    Although emergency department visit forecasting can be of use for nurse staff planning, previous research has focused on models that lacked sufficient resolution and realistic error metrics for these predictions to be applied in practice. Using data from a 1100-bed specialized care hospital with 553,000 patients assigned to its healthcare area, forecasts with different prediction horizons, from 2 to 24 weeks ahead, with an 8-hour granularity, using support vector regression, M5P, and stratified average time-series models were generated with an open-source software package. As overstaffing and understaffing errors have different implications, error metrics and potential personnel monetary savings were calculated with a custom validation scheme, which simulated subsequent generation of predictions during a 4-year period. Results were then compared with a generalized estimating equation regression. Support vector regression and M5P models were found to be superior to the stratified average model with a 95% confidence interval. Our findings suggest that medium and severe understaffing situations could be reduced in more than an order of magnitude and average yearly savings of up to €683,500 could be achieved if dynamic nursing staff allocation was performed with support vector regression instead of the static staffing levels currently in use.

    In this prospective study, superficial and deep swabs of all open fractures seen at the accident and emergency unit of our hospital between January and June 2000 were taken (before wound debridement was done or anitibiotics commenced). Routine microscopy, culture and sensitivities for aerobic and anaerobic organisms were carried out on these specimens. The organisms were cultured and identified using standard techniques and the antibiotic sensitivity testing was carried out using the disc diffusion method of Stokes. Within six hours of injury, single-organism isolates were commonly found whilst after 48 hours a mixed or poly-microbial organism load were isolated. In 90% of the positive isolates, the organisms isolated form the superficial and the deep swabs were the same. The antibiotic sensitivity pattern of all the isolates shows that pefloxacin, ciprofloxacin and ceftriaxone were more effective compared to cefuroxime and amoxycillin which had substantial resistance to most of the isolates. 41 fractures were followed to union and 4 (9.7%) developed osteomyelitis.

    In February 2012, the U.S. Nuclear Regulatory Commission (NRC) executed agreements with VTT Technical Research Centre of Finland, Nuclear Regulatory Authority of Japan (NRA, former JNES), Korea Institute of Nuclear Safety (KINS), Swedish Radiation Safety Authority (SSM), and Swiss Federal Nuclear Safety Inspectorate (ENSI) to establish the Program to Assess the Reliability of Emerging Nondestructive Techniques (PARENT). The goal of PARENT is to investigate the effectiveness of current emerging and perspective novel nondestructive examination procedures and techniques to find flaws in nickel-alloy welds and base materials. This is done by conducting a series of open and blind international round-robin tests on a set of large-bore dissimilar metal welds (LBDMW), small-bore dissimilar metal welds (SBDMW), and bottom-mounted instrumentation (BMI) penetration weld test blocks. The purpose of blind testing is to study the reliability of more established techniques and included only qualified teams and procedures. The purpose of open testing is aimed at a more basic capability assessment of emerging and novel technologies. The range of techniques applied in open testing varied with respect to maturity and performance uncertainty and were applied to a variety of simulated flaws. This paper will include a brief overview of the PARENT blind and open testing techniques and test blocks and present some of the blind testing results.

    Less than complete cholecystectomy has been advocated for difficult operative conditions for more than 100 years. These operations are called partial or subtotal cholecystectomy, but the terms are poorly defined and do not stipulate whether a remnant gallbladder is created. This article briefly reviews the history and development of the procedures and introduces new terms to clarify the field. The term partial is discarded, and subtotal cholecystectomies are divided into "fenestrating" and "reconstituting" types. Subtotal reconstituting cholecystectomy closes off the lower end of the gallbladder, reducing the incidence of postoperative fistula, but creates a remnant gallbladder, which may result in recurrence of symptomatic cholecystolithiasis. Subtotal fenestrating cholecystectomy does not occlude the gallbladder, but may suture the cystic duct internally. It has a higher incidence of postoperative biliary fistula, but does not appear to be associated with recurrent cholecystolithiasis. Laparoscopic subtotal cholecystectomy has advantages but may require advanced laparoscopic skills. PMID:26521077

    AIM: To study the etiopathogenesis, management and outcome of duodenal injury post laparoscopic cholecystectomy (LC). METHODS: A Medline search was carried out for all articles in English, on duodenal injury post LC, using the search word duodenal injury and LC. The cross references in these articles were further searched, for potential articles on duodenal injury, which when found was studied. Inclusion criteria included, case reports, case series, and reviews. Articles even with lack of details with some of the parameters studied, were also analyzed. The study period included all the cases published till January 2015. The data extracted were demographic details, the nature and day of presentation, potential cause for duodenal injury, site of duodenal injury, investigations, management and outcome. The model (fixed or random effect) for meta analyses was selected, based on Q and I2 statistics. STATA software was used to draw the forest plot and to compute the overall estimate and the 95%CI for the time of detection of injury and its outcome on mortality. The association between time of detection of injury and mortality was estimated using χ2 test with Yate’s correction. Based on Kaplan Meier survival curve concept, the cumulative survival probabilities at various days of injury was estimated. RESULTS: Literature review detected 74 cases of duodenal injury, post LC. The mean age of the patients was 58 years (23-80 years) with 46% of them being males. The cause of injury was due to cautery (46%), dissection (39%) and due to retraction (14%). The injury was noted on table in 46% of the cases. The common site of injury was to the 2nd part of the duodenum with 46% above the papilla and 15% below papilla and in 31% to the 1st part of duodenum. Duodenorapphy (primary closure) was the predominant surgical intervention in 63% with 21% of these being carried out laparoscopically. Other procedures included, percutaneous drainage, tube duodenostomy, gastric resection

    Late endocarditis after surgical repair of tetralogy of Fallot is rare. We describe a case of endocarditis following cholecystectomy in a 22-year old patient with repaired tetralogy of Fallot. After cholecystectomy, the patient was referred to a cardiology clinic with unexplained fever and suspicion of endocarditis. Echocardiography revealed a large mass at the basal level of interventricular septum. Endocarditis was diagnosed on the basis of clinical and echocardiographic findings and antibiotic treatment was initiated immediately. Nine days later, the clinical status of the patient deteriorated and urgent surgery was performed. Patch dehiscence which mimicked a large vegetation, and multiple vegetations on the patch were found during operation. The patch was removed and ventricular septum defect was repaired with a new dacron patch. Enterobacter agglomerans was isolated in the vegetation cultures. PMID:15856630

    Background and Aims: The use of regional anesthesia for laparoscopic cholecystectomy has been reserved for patients who are at high-risk under general anesthesia (GA). The aim of this study was to assess whether thoracic combined spinal epidural (CSE) anesthesia is a feasible option for American Society of Anesthesiologists (ASA) physical status I and II patients undergoing elective laparoscopic cholecystectomy. Material and Methods: Thirty ASA physical status I and II patients undergoing elective laparoscopic cholecystectomy received thoracic CSE anesthesia at T9-T10 or T10-T11 interspinous space using the midline approach. Two ml of isobaric levobupivacaine 0.5% with 25 μg of fentanyl was given intrathecally. Results: Surgery was conducted successfully in all except one patient. Thoracic CSE was performed at T9-T10 interspace in 25 patients and T10-T11 interspace in five patients. Paresthesia occurred in two patients (6.6%) transiently on Whitacre needle insertion that disappeared spontaneously. Dural puncture on epidural needle insertion occurred in one patient, and intrathecal placement of epidural catheter occurred in one. Ten patients (33%) complained of shoulder pain. Conversion to GA was done in one patient due to severe shoulder pain and anxiety. Hypotension occurred in 11 patients (36%) and all responded to single dose of mephenteramine 6 mg and fluid bolus. Bradycardia occurred in six patients (20%) which was managed in all with a single dose of atropine. Conclusion: Thoracic CSE anesthesia can be used effectively for ASA I and II patients undergoing laparoscopic cholecystectomy with significant postoperative benefits. PMID:27275054

    Objectives: To investigate effects of the positive end-expiratory pressure (PEEP) application of 10 cm H2O on the plasma levels of cytokines during laparoscopic cholecystectomy. Methods: A prospective study was conducted on 40 patients who presented to the Department of General Surgery, Medical Faculty, Turgut Özal University, Ankara, Turkey scheduled for laparoscopic cholecystectomy operation during a 10 month period from September 2012 to June 2013. Forty patients scheduled for laparoscopic cholecystectomy operation were randomly divided into 2 groups; ventilation through zero end-expiratory pressure (ZEEP) (0 cm H2O PEEP) (n=20), and PEEP (10 cm H2O PEEP) (n=20). All patients were ventilated with 8 ml/kg TV. Levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL 10, and transforming growth factor (TGF)-β1 were measured in the pre- and post-operatively collected samples. Results: Blood samples of 30 patients’ were analyzed for plasma cytokine levels, and 10 were excluded from the study due to hemolysis. Post-operative plasma IL-6 levels were observed to be significantly higher than the pre-operative patients (p=0.035). Post-operative plasma TGF-β1 levels in the PEEP group was found significantly higher compared with the pre-operative group levels (p=0.033). However, there were no significant differences in the pre- and post-operative plasma cytokine levels between the 2 groups. Conclusion: The application of PEEP of 10 cm H2O, which has known beneficial effect on respiratory mechanics, does not have any effect on systemic inflammatory response undergoing pneumoperitoneum during laparoscopic cholecystectomy surgery.

    Background: Cholecystectomy is considered as the most important and relatively common postoperative pain control often begins in recovery room by using systemic narcotics that may have some side effects. The aim of this study is to evaluate the effect of premedication with oral tizanidine on pain relief after elective laparoscopic cholecystectomy. Materials and Methods: In this double-blinded clinical trial, 70 adults of American Society of Anesthesiologist physiologic state 1 and 2 scheduled for elective laparoscopic cholecystectomy under general anesthesia were studied and randomly divided in two study and control groups. Ninety minutes before the induction of anesthesia, patients received either 4 mg tizanidine (study group) orally in 50cc or the same volume of plain water as a placebo (control group). Then, the vital signs, pain intensity, duration of stay in recovery, and the analgesic consumption were measured and then compared in both groups during 24 h postoperatively. Results: There was no significant difference in patient characteristics, with respect to age, weight, gender, and duration of anesthesia and surgery between the groups (P > 0.05). The pain intensity, need for analgesic drugs (34.57 ± 8.88 mg vs. 101.86 ± 5.08 mg), and the duration of stay in recovery room (67.43 ± 1.59 min vs. 79.57 ± 5.48 min) were significantly lower in tizanidine group than that of the control group. Conclusion: Oral administration of 4 mg tizanidine before laparoscopic cholecystectomy reduces postoperative pain, opioid consumption, and consequence of the duration of stay in recovery room without any complication.

    Introduction. Aim of this study was to evaluate the safety of laparoscopic cholecystectomy performed by residents. Materials and Methods. We retrospectively reviewed 569 elective laparoscopic cholecystectomies. Results. Duration of surgery was 84 ± 39 min for residents versus  66 ± 47 min for staff surgeons, P < 0.001. Rate of conversion was 3.2% for residents versus 2.7% for staff surgeons, P = 0.7. There was no difference in the rates of intraoperative and postoperative complications for residents (1.2% and 3.2%) versus staff surgeons (1.5% and 3.1%), P = 0.7 and P = 0.9. Postoperative hospital stay was 3.3 ± 1.8 days for residents versus  3.4 ± 3.2 days for staff surgeons, P = 0.6. One death in patients operated by residents (1/246) and one in patients operated by staff surgeons (1/323) were found, P = 0.8. No difference in the time to return to normal daily activities between residents (11.3 ± 4.2 days) and staff surgeons (10.8 ± 5.6 days) was found, P = 0.2. Shorter duration of surgery when operating the senior residents (75 ± 31 minutes) than the junior residents (87 ± 27 minutes), P = 0.003. Conclusion. Laparoscopic cholecystectomy performed by residents is a safe procedure with results comparable to those of staff surgeons. PMID:25379566

    Objectives: To test the effect of preoperative mannitol infusion on perioperative decreased cerebral oxygen saturation (rSO2) during laparoscopic cholecystectomy. Methods: Forty patients scheduled for laparoscopic cholecystectomy were enrolled in this study conducted at Dammam Hospital of the University, Dammam, Kingdom of Saudi Arabia from December 2013 to June 2014. Patients received either 0.5 g/kg of 20% intravenous mannitol infusion over 10 minutes before induction of anesthesia (group M), or an equal volume of normal saline instead (group C). Primary outcome variable was rSO2. Other variables included extubation time, clinical assessment of consciousness recovery using the Modified Observer’s Assessment of Alertness/Sedation Scale (OAA/S), and the mini-mental state examination (MMSE) for cognitive evaluation. Results: Anesthesia induction increased rSO2 in both groups. Pneumoperitoneum decreased rSO2 in group C, but not in group M. This drop in rSO2 in the group C reached its maximum 30 minutes after extubation, and was significantly less than the preinduction value. Time to extubation in group M was significantly shorter compared to group C (p=0.007). The OAAS in group M at 10 min after extubation was significantly higher compared to group C. No differences were found between the 2 groups in cognitive function as measured by MMSE score. Conclusion: Preoperative mannitol infusion maintains perioperative rSO2 during laparoscopic cholecystectomy and shortens extubation time with earlier resurgence of OAAS. PMID:26446331

    Aim To assess the feasibility and safety of laparoscopic cholecystectomy (LC) in very elderly patients with particular attention to the predicitive factors of difficulty. Patients and methods All patients aged ≥ 80 undergoing elective LC for lithiasis at our institution since 1st January 2015 to 31st December 2015 were included in the study. Exclusion criteria were: a) acute cholecystitis; b) biliary pancreatitis; c) biliary tract neoplasms; d) urgent procedure. Pre-, intra- and postoperative data were recorded. Results During the study period, we performed 72 LC and we enrolled 17 patients aged ≥ 80 with a M:F = 5:12. Of these, 10 patients had a “difficult” cholecystectomy. In seven cases an intraoperative cholangiography (IOC) was performed. Postoperative course was regular but in two patients we had an Oddian spasm in 1st postoperative day. Female sex (p=0.03) and preoperative high level of serum amylase (p= 0.02) were significantly associated to difficult cholecystectomy in elderly patients. Conclusion LC in octogenarians is feasible and safe. However, sex and serum amylase can help the surgeon to predict a more difficult procedure in elective LC. In this group of patients an approach based on the individual risk is desirable and the patient could be referred to a multidisciplinary approach. PMID:27381691

    Objective To evaluate the efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) on pain after laparoscopic cholecystectomy. Design A prospective, randomized, placebo-controlled, double-blind study. Setting A university hospital. Patients Fifty-two patients with cholelithiasis but without known allergy to one of the study drugs, history of bleeding, peptic ulcer disease, known cardiac, lung or renal disease, abnormal liver function or use of opiates or NSAIDs within 2 weeks before operation. Patients were assigned to one of three groups, and treatment was randomized by placing the drugs in sealed, numbered envelopes. Intervention Administration of the NSAIDs ketorolac, intramuscularly, or indomethacin, rectally, before laparoscopic cholecystectomy. Main Outcome Measures Postoperative pain scored on a visual analogue scale and by nurse assessment, total dose of fentanyl citrate given, and nausea or emesis. Results Patients in the placebo group reported significantly more pain than either NSAID group (p < 0.05) and were reported as having significantly more pain by the nurses (p < 0.05). These patients were subsequently treated with a higher mean postoperative dose of fentanyl citrate than either NSAID group (p < 0.05). Furthermore, the placebo group reported more nausea and emesis (p < 0.05). There was no significant difference in any of the parameters measured between the ketorolac or indomethacin group. Conclusions The data demonstrate that the NSAIDs ketolorac and indomethacin, administered preoperatively, decrease early postoperative pain and nausea after laparoscopic cholecystectomy and are equally efficacious in producing these results.

    During laparoscopy, members of staff spend time setting up and de-activating the light source, camera and insufflator. Voice Recognition Interface (VRI) devices, such as HERMES (Stryker Europe, Montreux, Switzerland), enable the surgeon to perform and control these and other functions. They recognize the surgeon's voice and adjust the instruments in response to programmed verbal commands. The aim of this study was to evaluate HERMES with regards to the utilization of time and theatre staff during laparoscopic cholecystectomy. A total of 100 patients were randomized to either HERMES-assisted or standard laparoscopic cholecystectomy. Three time variables were measured for performing three VRI tasks: (1) The initial setting up of the light source and camera, (2) the activation of the insufflator, and (3) the deactivation of the insufflator and light source at the end of the operation. The mean (and standard deviation) of the time in seconds required for setting up the light source and camera was 27.6 (26.9) in non-HERMES operations and 11.7 (4.7) in HERMES-assisted cases (p<0.001). Insufflation time was 19.8 (13.3) vs. 6.7 (2.5) (p<0.001), and switch-off time was 19.5 (11.8) vs. 11.8 (5.7) (p<0.001). HERMES optimized the operating time and the utilization of theatre staff during laparoscopic cholecystectomy. PMID:16754183

    The aim of the present prospective randomized controlled trial is to compare the effectiveness of intravenous and oral antibiotic prophylaxis for cost and surgical site infection in elective laparoscopic cholecystectomy. Three hundred twenty patients were split into two groups as to include 160 patients in each, and they were evaluated in a prospective and randomized fashion. While one group was subjected to 1 g cefazolin via intravenous route during anesthesia induction, other group received 1 g cephalexin monohydrate via oral route 1 h prior to the operation. Demographic findings and operation results of the patients were compared by analyses. Our 320 patients (278 females and 42 males) received elective cholecystectomy and were followed up for a period of 6-26 months. Each group had 160 patients. Both groups were similar with regard to demographic characteristics and inclusion criteria. Among all, only five (1.5 %) cases demonstrated postoperative surgical site infection. Surgical site infection at postoperative period was determined in three (1.8 %) cases of intravenous prophylaxis group and two (1.2 %) cases of oral prophylaxis group. There was no statistically significant difference between the groups in terms of surgical site infection. Oral antibiotic prophylaxis can be used in elective laparoscopic cholecystectomy prophylaxis due to its cost-effective, reliable nature, and low surgical site infection rate. PMID:26730079

    A commonly used diagnostic criterion for sphincter of Oddi dysfunction is delayed drainage of contrast media from the bile ducts at endoscopic retrograde cholangiography (ERC), which is defined as the persistence of contrast greater than 45 min after injection. We performed ERC in 11 asymptomatic post-cholecystectomy volunteers for the purpose of evaluating biliary drainage time. In an attempt to more accurately quantify emptying, concomitant scintigraphy was performed at the time of ERC and contrast drainage. Sufficient contrast mixed with technetium-99m sulfur colloid to completely fill out the intra-hepatic tree was injected (mean volume, 9 ml) and the volunteers remained in the prone position during imaging. The length of time from cholecystectomy, bile duct size, volume of contrast injected, and scintigraphic T1/2s did not correlate with drainage time at ERC. At 45 min after injection the degree of residual contrast filling was scored as: empty in three volunteers, almost empty in one, one-fourth full in 5, and one-half full in two. Therefore, 7 of the 11 asymptomatic volunteers (63%) had delayed drainage. Even if more stringent criteria for delayed drainage were used (ducts one-half filled), 2 of the 11 (18%) had abnormal drainage. The frequent occurrence of delayed drainage in these asymptomatic post-cholecystectomy volunteers challenges the validity of the 45-min delayed drainage criterion for sphincter of Oddi dysfunction.

    Objective: We analyzed circulating TNF-α and IL-6 to determine systemic inflammatory responses associated with transvaginal cholecystectomy in a porcine model. Methods: Six female pigs were used for a survival study after transvaginal cholecystectomy (NOTES group) using endoscopic submucosal dissection (ESD) instruments and a single-channel endoscope. Blood was drawn preoperatively and 24 hours and 48 hours postoperatively. Four pigs were used as controls. In addition, laparoscopic cholecystectomy was performed in 2 pigs for laparoscopic control. Results: In all 6 pigs in the NOTES group, no major intraoperative complications occurred. No significant differences were found between control, laparoscopic, and NOTES groups in terms of preoperative IL-6 level (P=0.897) and at 24 hours (P=0.790), and 48 hours postoperatively (P=0.945). Similarly, there was no significant difference in mean preoperative (P=0.349) and mean day 2 postoperative TNF-α levels (P=0.11). But a significant increase in day 1 postoperative TNF-α levels in the laparoscopic group compared with that in the control and NOTES groups was observed (P=0.049). One limitation of our study is that the sample size was relatively small. Conclusion: NOTES is safe in animal models in terms of anatomical and cellular level changes with minimal systemic inflammatory host responses elicited. Further study needs to be carried out in humans before NOTES can be recommended for routine use. PMID:19366533

    AIM: To apply the laparoscopic and endoscopic cooperative surgery concept, we investigated whether endoscopic cholecystectomy could be performed more safely and rapidly via only 1 port or not. METHODS: Two dogs (11 and 13-mo-old female Beagle) were used in this study. Only 1 blunt port was created, and a flexible endoscope with a tip attachment was inserted between the fundus of gallbladder and liver. After local injection of saline to the gallbladder bed, resection of the gallbladder bed from the liver was performed. After complete resection of the gallbladder bed, the gallbladder was pulled up to resect its neck using the Ring-shaped thread technique. The neck of the gallbladder was cut using scissor forceps. Resected gallbladder was retrieved using endoscopic net forceps via a port. RESULTS: The operation times from general anesthetizing with sevoflurane to finishing the closure of the blunt port site were about 50 min and 60 min respectively. The resection times of gallbladder bed were about 15 min and 13 min respectively without liver injury and bleeding at all. Feed were given just after next day of operation, and they had a good appetite. Two dogs are in good health now and no complications for 1 mo after endoscopic cholecystectomy using only a flexible endoscope via one port. CONCLUSION: We are sure of great feasibility of endoscopic cholecystectomy via single port for human. PMID:27053847

    Background and Aims: Postsurgical pain is the leading complaint after laparoscopic cholecystectomy that may delay the postoperative recovery and hence we undertook a prospective randomized trial to analyze the role of flupirtine as a preemptive analgesic for postoperative pain relief in patients undergoing above surgery. Material and Methods: A total of 66 cases were randomly assigned to two groups to receive capsule flupirtine (200 mg) or capsule vitamin B complex administered orally, 2 h before the laparoscopic cholecystectomy surgery. Time to first analgesic requirement, assessment of postoperative pain in terms of visual analog score, and analgesic requirement postoperatively were measured as a primary outcome. Results: Time to first analgesic requirement was significantly prolonged in the flupirtine group as compared with the placebo group. There was significant pain reduction in early postoperative period (up to 4 h), but no changes occurred thereafter. Total analgesic requirement (including rescue analgesia) and side-effects were comparable between the groups except for higher sedation in flupirtine group. Conclusions: Flupirtine is effective as a preemptive analgesic in providing adequate pain relief during the immediate postoperative period after laparoscopic cholecystectomy surgery. However, continuation of drug therapy postoperatively could possibly delineate its optimal analgesic profile more profoundly. PMID:25948895

    The management of patients with symptoms consistent with biliary tract disease who do not have gallstones is difficult. We retrospectively reviewed the charts of 18 patients who underwent cholecystokinin cholescintigraphy at our institution to determine if this procedure was reliable in identifying patients who would benefit from cholecystectomy. All patients underwent biliary screening, and a gallbladder ejection fraction of less than or equal to 35% was considered abnormal. None of the patients had evidence of gallstones by ultrasound. There were 11 patients with abnormal ejection fractions. All 11 patients (100%) had "classic" biliary colic and underwent cholecystectomy. The pathologic diagnosis was chronic cholecystitis in every patient. All patients had complete relief of their symptoms postoperatively with a mean follow-up of 10 months. There were six patients with normal ejection fractions. Only one patient in this group had "classic" biliary colic. This patient had a gallbladder ejection fraction of 38% and endoscopic evidence of gastritis. This patient remains symptomatic despite H2 blockade. The remaining five patients had nonspecific right upper quadrant or epigastric pain. These patients had endoscopic evidence of gastritis, and symptoms were relieved with H2 blockade. The remaining patient had an indeterminate scan due to radioactivity in the duodenum overlying the gallbladder and was excluded from this analysis. Cholecystokinin cholescintigraphy is a useful test in identifying those patients with biliary dyskinesia or acalculous cholecystitis who will benefit from cholecystectomy. PMID:8273847

    This study investigates the effectiveness of preoperative very low-calorie diet (VLCD) in laparoscopic cholecystectomy. A prospective observational study of consecutive patients undergoing laparoscopic cholecystectomy was undertaken. At the preoperative visit, all patients were advised to adhere to VLCD for 2 weeks before surgery (<800 kcal/d). Patients were judged to have complied with the VLCD if weight loss >2 kg. Technical difficulty was assessed using questionnaires. A total of 38 patients met the inclusion criteria. Difficulty of visualization and dissection of Calot's triangle in obese patients was twice that of nonobese patients (P=0.01). In 62% of procedures involving obese VLCD noncompliant patients, the surgeon experienced ≥1 area of technical difficulty, compared with 0% of procedures on obese, compliant patients (P=0.018). Difficulty of dissection of the gallbladder bed was 3 times higher in obese, noncompliant patients, compared with obese, compliant patients (P=0.07). Adherence to a 2-week preoperative VLCD may reduce technical difficulty of laparoscopic cholecystectomy in obese patients. PMID:27258913

    2009-01-01

    Background Gallstones represent the most common cause of acute pancreatitis in Sweden. Epidemiological data concerning timing of cholecystectomy and sphincterotomy in patients with first attack of mild acute biliary pancreatitis (MABP) are scarce. Our aim was to analyse readmissions for biliary disease, cholecystectomy within one year, and mortality within 90 days of index admission for MABP. Methods Hospital discharge and death certificate data were linked for patients with first attack acute pancreatitis in Sweden 1988-2003. Mortality was calculated as case fatality rate (CFR) and standardized mortality ratio (SMR). MABP was defined as acute pancreatitis of biliary aetiology without mortality during an index stay of 10 days or shorter. Patients were analysed according to four different treatment policies: Cholecystectomy during index stay (group 1), no cholecystectomy during index stay but within 30 days of index admission (group 2), sphincterotomy but not cholecystectomy within 30 days of index admission (group 3), and neither cholecystectomy nor sphincterotomy within 30 days of index admission (group 4). Results Of 11636 patients with acute biliary pancreatitis, 8631 patients (74%) met the criteria for MABP. After exclusion of those with cholecystectomy or sphincterotomy during the year before index admission (N = 212), 8419 patients with MABP remained for analysis. Patients in group 1 and 2 were significantly younger than patients in group 3 and 4. Length of index stay differed significantly between the groups, from 4 (3-6) days, (representing median, 25 and 75 percentiles) in group 2 to 7 (5-8) days in groups 1. In group 1, 4.9% of patients were readmitted at least once for biliary disease within one year after index admission, compared to 100% in group 2, 62.5% in group 3, and 76.3% in group 4. One year after index admission, 30.8% of patients in group 3 and 47.7% of patients in group 4 had undergone cholecystectomy. SMR did not differ between the four

    A comparison of 1-port, 2-port, 3-port, and 4-port laparoscopic cholecystectomy techniques from the point of view of workflow criteria was made to both identify specific workflow components that can cause surgical disturbances and indicate good and bad practices. As a case study, laparoscopic cholecystectomies, including manual tasks and interactions within teamwork members, were video-recorded and analyzed on the basis of specially encoded workflow information. The parameters for comparison were defined as follows: surgery time, tool and hand activeness, operator's passive work, collisions, and operator interventions. It was found that 1-port cholecystectomy is the worst technique because of nonergonomic body position, technical complexity, organizational anomalies, and operational dynamism. The differences between laparoscopic techniques are closely linked to the costs of the medical procedures. Hence, knowledge about the surgical workflow can be used for both planning surgical procedures and balancing the expenses associated with surgery. PMID:27438171

    Aim: The aim of this study was to determine the effect of sodium bicarbonate irrigation versus normal saline irrigation in patients undergoing a laparoscopic cholecystectomy. Background: Pain in patients undergoing laparoscopic cholecystectomy is the most common complaint, especially in the abdomen, back, and shoulder region. Patients and methods: In a double blind randomized clinical trial, 150 patients were assigned to the three groups (50 patients in each group). Group A received intraperitoneal irrigation normal saline (NS). Groups B and C received irrigation sodium bicarbonate and none irrigation, respectively. Pain was assessed using a visual analog scale (VAS) for 6, 18 and 24 hours postoperatively, as well as one week after the surgery. Data analysis was performed using SPSS ver18 and chi-square, Fisher’s Exact Test, on-way ANOVA and repeated measure ANOVA tests. Results: Patients in groups showed no significant difference in terms of age, gender, past medical history and smoking history (p>0.05). Left shoulder tip pain was significantly lower only between the sodium bicarbonate group and non-washing group at 6, 18, and 24 hours postoperatively (P=0.04, P=0.02 and P=0.009 respectively). There was no significant difference between the three treatment groups in right shoulder tip pain, back pain and port site incisional pain. Conclusion: In laparoscopic cholecystectomy, peritoneal irrigation with sodium bicarbonate may reduce the intensity of postoperative shoulder tip pain and is an effective method for improving the quality of life within the early recovery period.

    AIM: To investigate the learning curve of transumbilical suture-suspension single-incision laparoscopic cholecystectomy (SILC). METHODS: The clinical data of 180 consecutive transumbilical suture-suspension SILCs performed by a team in our department during the period from August 2009 to March 2011 were retrospectively analyzed. Patients were divided into nine groups according to operation dates, and each group included 20 patients operated on consecutively in each time period. The surgical outcome was assessed by comparing operation time, blood loss during operation, and complications between groups in order to evaluate the improvement in technique. RESULTS: A total of 180 SILCs were successfully performed by five doctors. The average operation time was 53.58 ± 30.08 min (range: 20.00-160.00 min) and average blood loss was 12.70 ± 11.60 mL (range: 0.00-100.00 mL). None of the patients were converted to laparotomy or multi-port laparoscopic cholecystectomy. There were no major complications such as hemorrhage or biliary system injury during surgery. Eight postoperative complications occurred mainly in the first three groups (n = 6), and included ecchymosis around the umbilical incision (n = 7) which resolved without special treatment, and one case of delayed bile leakage in group 8, which was treated by ultrasound-guided puncture and drainage. There were no differences in intraoperative blood loss, postoperative complications and length of postoperative hospital stay among the groups. Bonferroni’s test showed that the operation time in group 1 was significantly longer than that in the other groups (F = 7.257, P = 0.000). The majority of patients in each group were discharged within 2 d, with an average postoperative hospital stay of 1.9 ± 1.2 d. CONCLUSION: Following scientific principles and standard procedures, a team experienced in multi-port laparoscopic cholecystectomy can master the technique of SILC after 20 cases. PMID:23922478

    Background: Nonsteroidal anti-inflammatory drugs used for postoperative analgesia have considerable adverse effects, with paracetamol having a different mechanism of action, superior side effect profile and availability in intravenous (IV) form, this study was conducted to compare intra-peritoneal bupivacaine with IV paracetamol for postoperative analgesia following laparoscopic cholecystectomy. Aim: The aim was to compare the efficacy of intra-peritoneal administration of bupivacaine 0.5% and IV acetaminophen for postoperative analgesia in patients undergoing laparoscopic cholecystectomy. Settings and Design: Randomized, prospective trial. Materials and Methods: A total of 60 patients of American Society of Anesthesiologists physical Status I and II scheduled for laparoscopic cholecystectomy were enrolled for this study. Group I received 2 mg/kg of 0.5% bupivacaine as local intra-peritoneal application and Group II patients received IV 1 g paracetamol 6th hourly. Postoperatively, the patients were assessed for pain utilizing Visual Analog Scale (VAS), Visual Rating Prince Henry Scale (VRS), shoulder pain. The total number of patients requiring rescue analgesia and any side-effects were noted. Statistical Analysis: Data analysis was performed using Students unpaired t-test. SPSS version 11.5 was used. Results: The VAS was significantly higher in Group I compared with Group II at 8th, 12th and 24th postoperative hour. At 1st and 4th postoperative hours, VAS was comparable between the two groups. Although the VRS was higher in Group I compared with Group II at 12th and 24th postoperative hour; the difference was statistically significant only at 24th postoperative hour. None of the patients in either of the groups had shoulder pain up to 8 h postoperative. The total number of patients requiring analgesics was higher in Group II than Group I at 1st postoperative hour.

    Laparoscopic cholecystectomy (LC) is currently the gold standard treatment for symptomatic cholelithiasis. LC is actually condidered a medium complexity surgical operation. LC could be technically hard, especially if patient underwent previous surgical operation. These difficulties increase in outcome of previous operation in right upper quadrant (RUQ): in this case laparoscopic access is defined as an "hard access". We present two cases in which an unconventional access was performed: laparoscopic cholecistectomy is a safe and feasible procedure, although a careful assessment preoperative is indispensable. In particular, caution is required in both the triangulation of the trocar, which in pneumoperitoneum induction. PMID:25183639

    The implications of laparoscopic cholecystectomy (LC) for radiology were assessed by comparing imaging investigations in 48 LC and 48 conventional cholecystectomy (CC) patients. In addition, we attempted to identify findings on pre-operative ultrasound (US) which predicted operative difficulties at LC. There were no per-operative or T-tube cholangiograms in the LC patients, but otherwise the pattern of investigation was similar in both groups. Forty of the 48 CC patients underwent cholangiography (per-operative cholangiography in 36, endoscopic retrograde cholangiopancreatography (ERCP) in two, and both in two) demonstrating calculi in eight (16.7%) cases. Only four LC patients had cholangiography (ERCP in all cases) demonstrating common bile duct (CBD) calculi in one (2.1%) case. Ultrasound failed to identify the gall-bladder with certainty in three of the five failed LC cases. Neither gall-bladder wall thickness, contraction nor calculus size on pre-operative US served as predictors of other per-operative difficulties. Our results indicate that there may be some patients with retained CBD calculi in the LC group. The role of pre-operative US in predicting operative difficulties needs further assessment in a prospective study. PMID:1395385

    Laparoscopic cholecystectomy (LC) has the advantages of early return to full daily activity, early return to work, and better cosmetic result, as well as quickly resolving pain. Yet how this information about the procedure influences a patient's attitude toward laparocopy is not known. In this study we analyzed the factors that play role in the decision-making process of patients who choose laparoscopic surgery, and we also evaluated patients' knowledge of laparoscopy and their expectations. A questionnaire was used in evaluating 98 patients suffering from symptomatic cholelithiasis scheduled for elective laparoscopic cholecystectomy between January 2001 and January 2002. Females constituted 81% of the study population. Most of the patients (56%) were housewives. While 45% of the patients had an educational status of primary school degree only, 14% had graduated from a university. Forty-three patients described their level of knowledge about laparoscopy as "low" (had only heard about laparoscopy). In 61% of the patients the surgeon was the sole decision maker about the type of the operation. Almost none of the patients had a preference for the time of discharge from the hospital after surgery, and only three of the actively working patients offered a time interval for return to work. From this study we concluded that most patients have inadequate information about laparoscopic surgery, that the type of operation is dictated mostly by the surgeon, and that early discharge and early return to work are not important for many patients.

    Background In laparoscopic surgical procedures, many clinicians recommend supraglottic airway devices as good alternatives to intubation. We compared the i-gel® (i-gel) and LMA Supreme® (Supreme Laryngeal Mask Airway, SLMA) airway devices during laparoscopic cholecystectomy regarding sealing pressure and respiratory parameters before, during, and after pneumoperitoneum. Methods Following Institutional Review Board approval and written informed consent, 93 patients were randomly allocated into the i-gel (n = 47) or SLMA group (n = 46). Insertion time, number of insertion attempts, and fiberoptic view of glottis were recorded. Oropharyngeal leak pressure (OLP), the use of airway manipulation, peak inspiratory pressure, lung compliance, and hemodynamic parameters were measured before, during, and after pneumoperitoneum. Results There were no significant differences between the two groups regarding demographic data, insertion time, fiberoptic view of glottis, and the use of airway manipulation. The gastric tube insertion time was longer in the i-gel group (20.4 ± 3.9 s) than in the SLMA group (16.7 ± 1.6 s) (P < 0.001). All devices were inserted on the first attempt, excluding one case in each group. Peak inspiratory pressure, lung compliance, and OLP changed following carbon dioxide pneumoperitoneum in each group, but there were no significant differences between the groups. Conclusions Both the i-gel and SLMA airway devices can be comparably used in patients who undergo laparoscopic cholecystectomy, and they offer similar performance including OLP. PMID:26495055

    Gallbladder carriage of invasive Salmonella is considered fundamental in sustaining typhoid fever transmission. Bile and tissue was obtained from 1,377 individuals undergoing cholecystectomy in Kathmandu to investigate the prevalence, characteristics and relevance of invasive Salmonella in the gallbladder in an endemic area. Twenty percent of bile samples contained a Gram-negative organism, with Salmonella Typhi and Salmonella Paratyphi A isolated from 24 and 22 individuals, respectively. Gallbladders that contained Salmonella were more likely to show evidence of acute inflammation with extensive neutrophil infiltrate than those without Salmonella, corresponding with higher neutrophil and lower lymphocyte counts in the blood of Salmonella positive individuals. Antimicrobial resistance in the invasive Salmonella isolates was limited, indicating that gallbladder colonization is unlikely to be driven by antimicrobial resistance. The overall role of invasive Salmonella carriage in the gallbladder is not understood; here we show that 3.5% of individuals undergoing cholecystectomy in this setting have a high concentration of antimicrobial sensitive, invasive Salmonella in their bile. We predict that such individuals will become increasingly important if current transmission mechanisms are disturbed; prospectively identifying these individuals is, therefore, paramount for rapid local and regional elimination.

    Purpose. The recurrence of CBD stone is still observed in a considerable number of patients. The study was to evaluate the risk factors for recurrence of symptomatic CBD stone in patients who underwent cholecystectomy after the removal of CBD stone. Methods. The medical records of patients who underwent removal of CBD stone with subsequent cholecystectomy were reviewed. The risk factors for the recurrence of symptomatic CBD stone were compared between the recurrence and the nonrecurrence group. Results. The mean follow-up period was 40.6 months. The recurrence of symptomatic CBD stones was defined as the detection of bile duct stones no sooner than 6 months after complete clearance of CBD stones, based on symptoms or signs of biliary complication. 144 patients (68 males, 47.2%) were finally enrolled and their mean age was 59.8 (range: 26~86) years. The recurrence of CBD stone occurred in 15 patients (10.4%). The mean period until first recurrence was 25.9 months. The presence of type 1 or 2 periampullary diverticulum and multiple CBD stones were the independent risk factors. Conclusion. For the patients with type 1 or 2 periampullary diverticulum or multiple CBD stones, careful followup is needed for the risk in recurrence of symptomatic CBD stone. PMID:22991508

    A prospective observational study was done on 50 patients to investigate the haemodynamic and end tidal CO₂ (EtCO₂) changes in healthy patients without cardiopulmonary pathology during elective laparoscopic cholecystectomy in head up position under standard protocol of general anaesthesia. During surgery, intra abdominal pressure was maintained at 15 mmHg by a CO₂ insufflator and minute ventilation was controlled with a constant tidal volume and fixed respiratory rate. Haemodynamic parameters, EtCO₂, SpO₂ and ECG were recorded before and after induction and positioning of the patients and at 5 minutes interval for the first 30 minutes, then 10 minutes interval for the rest of the period. Highly significant increase (p<0.001) in pulse rate, systolic, diastolic and mean arterial pressure occurred at 30 minutes after insufflations and positioning of the patient. A very highly significant (p<0.001) increase in EtCO₂ from the base line was at 40 minutes after insufflations and positioning of the patients. There was no change in SpO₂ and ECG. This study supports the significant physiological changes in terms of haemodynamic and EtCO₂ during laparoscopic cholecystectomy and recommends the meticulous monitoring of these parameters during the surgery and balance the benefit of laparoscopy against the intra operative risk.

    Background Nefopam is a centrally acting analgesic that is used to control pain. The aim of this study was to find an appropriate dose of nefopam that demonstrates an analgesic effect when administered in continuous infusion with fentanyl at the end of laparoscopic cholecystectomy. Methods Ninety patients scheduled for laparoscopic cholecystectomy were randomly assigned to receive analgesia with fentanyl alone (50 µg, Group 1, n = 30), or with fentanyl in combination with nefopam 20 mg (Group 2, n = 30) or in combination with nefopam 40 mg (Group 3, n = 30) at the end of surgery. Pain and side effects were evaluated at 10 minutes, 30 minutes, 1 hour, 2 hours, 6 hours, and 12 hours after arrival in the post-anesthesia care unit (PACU). Results Pain was statistically significantly lower in Groups 2 and 3 than in Group 1 at 10 minutes, 2 hours, and 6 hours after arrival in the PACU. Nausea was statistically significantly lower in Group 2 than in Groups 1 and 3 at 10 minutes after arrival in the PACU. Shivering was statistically significantly lower in Groups 2 and 3 than in Group 1 at 10 minutes after arrival in the PACU. Conclusions Nefopam is a drug that can be safely used as an analgesic after surgery, and its side effects can be reduced when fentanyl 50 µg is injected with nefopam 20 mg. PMID:24156002

    Objective: Many surgeons face difficulties during single-incision laparoscopic cholecystectomy (SILC) surgery and are forced to use an additional port. We compared the results of a technique that we developed with SILC. Material and Methods: Fifty-four patients who were diagnosed with chronic cholelithiasis were prospectively randomized and divided into two groups. An additional 5-mm port (MCAP: with an additional port using a multi-channel device through the umbilicus) was placed in the subxiphoid area instead of a transabdominal suspension suture in one group of patients. The other group was operated on with the SILC technique. The demographic and surgical data of the patients were compared. Results: The MCAP technique shortened the surgery duration by more than half (MCAP: 35.0±12.3, SILC: 79.1±27.7 min) (p<0.05). No difference was found between the two methods in terms of estimated blood loss, length of hospitalization, postoperative day 1 and 7 visual analog scale scores, need for analgesia in the postoperative period, and rate of changing to another technique due to inadequacy of the surgical technique. Conclusion: MCAP is as safe as SILC for cholecystectomy and is easier for the surgeon to perform. PMID:25931927

    Summary Background Spillage of gallstones in the abdominal cavity may rarely occur during the course of laparoscopic cholecystectomy. Dropped gallstones in the peritoneal and extra-peritoneal cavity are usually asymptomatic. However, they may lead to abscess formation with an estimated incidence of about 0.3%. Common locations of the abscess are in the abdominal wall followed by the intra-abdominal cavity, usually in the sub-hepatic or retro-peritoneum inferior to the sub-hepatic space. Case Report We hereby describe an unusual case of infected spilled gallstones in the right sub-phrenic space, prospectively detected on abdominal MRI performed two years after laparoscopic cholecystectomy, in a patient with only a mild right-sided abdominal complaint. Conclusions This case highlights the role of MRI in suggesting the right diagnosis in cases with vague or even absent symptomatology. In our case the patient’s history together with high quality abdomen MRI allowed the correct diagnosis. Radiologists should be aware of this rare and late onset complication, even after many years from surgery as an incidental finding in almost asymptomatic patients. PMID:27471576

    Background Endoscopic retrograde cholangiography (ERCP) with endoscopic sphincterotomy (ES) followed by a laparoscopic cholecystectomy (LC) is generally accepted as the treatment of choice for patients with choledochocystolithiasis who are eligible for surgery. Previous studies have shown that LC after ES is associated with a high conversion rate. The aim of the present study was to assess the complexity of LC after ES compared with standard LC for symptomatic uncomplicated cholecystolithiasis. Methods The study population consisted of two patient cohorts: patients who had undergone a previous ERCP with ES for choledocholithiasis (PES) and patients with cholecystolithiasis who had no previous intervention prior to LC (NPES). Results The PES group consisted of 93 patients and the NPES group consisted of 83 consecutive patients. Patients in the PES group had higher risks for longer [more than 65 min, odds ratio (OR) = 4.21 (95% confidence interval (CI) 1.79–9.91)] and more complex [higher than 6 points, on a 0–10 scale, OR 3.12 (95% CI 1.43–6.81)] surgery. The conversion rate in the PES and NPES group (6.5% versus 2.4%, respectively) and the complication rate (12.9% versus 9.6%, respectively) were not significantly different. Discussion A laparoscopic cholecystectomy after ES is lengthier and more difficult than in uncomplicated cholelithiasis and should therefore be performed by an experienced surgeon. PMID:23374364

    This study describes the value of endoscopic retrograde cholangiopancreatography (ERCP) in patients with bile duct injury after laparoscopic cholecystectomy. Twelve consecutive patients were studied over a one year period. In all patients the biliary tree was visualised during ERCP. Four patients had complete bile duct obstruction, seven patients had a stricture (two with concomitant leakage), and one patient had leakage from a hepatic branch. Three patients with complete obstruction, presented with a relatively prolonged symptom free, 'silent' period before diagnosis. In all four patients with complete transection, a proximal hepaticojejunostomy was performed. In one patient with a tough fibrous stricture, secondary to incorrect clip placement, passage of the guidewire was impossible, leaving surgical reconstruction as the only therapeutic option. All remaining seven patients with leakage or strictures, or both were successfully treated by endoscopic sphincterotomy only (n = 1) or sphincterotomy and subsequent stent placement (n = 6). When patients do not recover uneventfully after laparoscopic cholecystectomy even without cholestasis or jaundice, early ERCP is recommended as a safe and valuable method to detect bile duct injury and to suggest treatment. Subsequently, more than half of such patients can be treated endoscopically. Extended follow up is needed to evaluate the longterm results. Images Figure 1 Figure 2 Figure 3 Figure 4 PMID:8406163

    Transversus abdominis plane (TAP) block technique seems to offer one of the most efficient methods for a local pain control. Our aim is to demonstrate the effectiveness and safety of TAP block for post-operative pain control under laparoscopic vision in elderly patients during laparoscopic cholecystectomy. The patients aged more than 65 years old, who had cholecystectomy due to symptomatic cholelithiasis, were retrospectively evaluated. The patients that were operated under general anesthesia + laparoscopic TAP block and those who were operated only under only general anesthesia were compared according to their’ age and gender, comorbidities, American Society of Anesthesiologists scores, visual analog scale (VAS) for pain and length of stay in the hospital. Median (±interquartile range) values of post-operative 24th-hour-VAS for pain was found consecutively 2 (±1-3) in TAP block + group and 3 (±2-5) in TAP block - group. The median post-operative 24th-hour-VAS value in overall patients was three. Patients’ VAS values were higher in the TAP block – group with a statistically significant difference (p = 0.001). Furthermore, no statistically significant difference was found for other parameters in two groups. The laparoscopic-guided TAP block can easily be performed and has potential for lower visceral injury risk and shorter operational time. Efficacy, safety and other advantages (analgesic requirements, etc.) make it an ideal abdominal field block in elderly patients. PMID:26773187

    Background: Postoperative pain is the primary reason for prolonged hospital stay after laparoscopic cholecystectomy. This study compared the effect of a single oral preoperative administration of paracetamol (1 g) with 2 different doses of pregabalin (150 or 300 mg) for attenuating postoperative pain and analgesic consumption. Materials and Methods: Seventy-five patients, aged 18-60 years, American Society of Anesthesiologists’ physical status I and II undergoing elective laparoscopic cholecystectomy were included in this randomized controlled study. Patients were divided into three groups, 25 each to receive either oral paracetamol 1 g (group I, control group) or pregabalin 150 (group II) or 300 mg (group III), 2 h before surgery. Postoperative pain was evaluated based on visual analog scale over a period of 6 h and 1st time for rescue analgesia. Postoperative sedation, hemodynamic changes, serum cortisol level, and side effects were also evaluated. Results: There was a significant decrease in mean heart rate, mean systolic blood pressure, sedation score, pain score, and delayed the first request for analgesics postoperatively in group (II) and group (III) compared to group (I) 2 h postoperatively. There was no significant difference in group (III) compared to group (II) postoperatively. The incidence of postoperative side effects was more in group (III). Conclusion: The single oral preoperative dose administration of pregabalin had significant opioid-sparing effect in the first 6 h after surgery, whereas side effects were more common with administration of pregabalin 300 mg.

    Acute cholecystitis in patients unfit for general anesthesia often initially requires cholecystectomy tube placement without cholecystectomy. The best way to definitively manage those patients with irreversible medical conditions, leaving them unable to undergo cholecystectomy, has yet to be defined. Laser lithotripsy is currently used in the management of stones of the genitourinary system. Extracorporeal shock wave cholelithotripsy has been extensively evaluated in Munich, Germany and since then, has been abandoned as an alternative treatment of cholelithiasis. This report discusses a novel approach using established cholecystocutaneous fistula tracts and laser lithotripsy to definitively treat this group of patients. PMID:24300938

    Fibromyalgia, a chronic syndrome of diffuse musculoskeletal pain and somatic hyperalgesia from central sensitization, is very often comorbid with visceral pain conditions. In fibromyalgia patients with gallbladder calculosis, this study assessed the short and long-term impact of laparoscopic cholecystectomy on fibromyalgia pain symptoms. Fibromyalgia pain (VAS scale) and pain thresholds in tender points and control areas (skin, subcutis and muscle) were evaluated 1week before (basis) and 1week, 1,3,6 and 12months after laparoscopic cholecystectomy in fibromyalgia patients with symptomatic calculosis (n = 31) vs calculosis patients without fibromyalgia (n. 26) and at comparable time points in fibromyalgia patients not undergoing cholecystectomy, with symptomatic (n = 27) and asymptomatic (n = 28) calculosis, and no calculosis (n = 30). At basis, fibromyalgia+symptomatic calculosis patients presented a significant linear correlation between the number of previously experienced biliary colics and fibromyalgia pain (direct) and muscle thresholds (inverse)(p<0.0001). After cholecystectomy, fibromyalgia pain significantly increased and all thresholds significantly decreased at 1week and 1month (1-way ANOVA, p<0.01-p<0.001), the decrease in muscle thresholds correlating linearly with the peak postoperative pain at surgery site (p<0.003-p<0.0001). Fibromyalgia pain and thresholds returned to preoperative values at 3months, then pain significantly decreased and thresholds significantly increased at 6 and 12months (p<0.05-p<0.0001). Over the same 12-month period: in non-fibromyalgia patients undergoing cholecystectomy thresholds did not change; in all other fibromyalgia groups not undergoing cholecystectomy fibromyalgia pain and thresholds remained stable, except in fibromyalgia+symptomatic calculosis at 12months when pain significantly increased and muscle thresholds significantly decreased (p<0.05-p<0.0001). The results of the study show that biliary colics from

    AIM: To investigate the feasibility and safety of Natural orifice trans-umbilical endoscopic cholecystectomy with a water-jet hybrid-knife in a non-survival porcine model. METHODS: Pure natural orifice transluminal endoscopic surgery (NOTES) cholecystectomy was performed on three non-survival pigs, by transumbilical approach, using a water-jet hybrid-knife. Under general anesthesia, the following steps detailed the procedure: (1) incision of the umbilicus followed by the passage of a double-channel flexible endsocope through an overtube into the peritoneal cavity; (2) establishment of pneumoperitoneum; (3) abdominal exploration; (4) endoscopic cholecystectomy: dissection of the gallbladder performed using water jet equipment, ligation of the cystic artery and duct conducted using nylon loops; and (5) necropsy with macroscopic evaluation. RESULTS: Transumbilical endoscopic cholecystectomy was successfully completed in the first and third pig, with minor bleedings. The dissection times were 137 and 42 min, respectively. The total operation times were 167 and 69 min, respectively. And the lengths of resected specimen were 6.5 and 6.1 cm, respectively. Instillation of the fluid into the gallbladder bed produced edematous, distended tissue making separation safe and easy. Reliable ligation using double nylon loops insured the safety of cutting between the loops. There were no intraoperative complications or hemodynamic instability. Uncontrolled introperative bleeding occurred in the second case, leading to the operation failure. CONCLUSION: Pure NOTES trans-umbilical cholecystectomy with a water-jet hybrid-knife appears to be feasible and safe. Further investigation of this technique with long-term follow-up in animals is needed to confirm the preliminary observation. PMID:24187461

    Context: To assess the analgesic efficacy of the combination of bupivacaine and buprenorphine in alleviating postoperative pain following laparoscopic cholecystectomy. Aims: Laparoscopic cholecystectomy is comparatively advantageous as it offers less pain in the postoperative period and requires a shorter hospital stay. There are only a few studies performed to evaluate the analgesic efficacy of intraperitoneal instillation of buprenorphine and bupivacaine during laparoscopic cholecystectomy. Settings and Design: The present research is a randomized, double-blind controlled study conducted in the Department of Anaesthesiology, Dayanand Medical College and Hospital Ludhiana, Punjab after formal ethical approval from Hospital's Ethics Committee. Subjects and Methods: This study analyzed 90 adults admitted for elective laparoscopic cholecystectomy. After the procedure, subjects were divided into three equal groups to conduct the study. Three Groups A, B, and C had intraperitoneal instillation of the 25 ml of physiological saline (0.9% normal saline), 0.25% of bupivacaine, 0.25% bupivacaine, and 0.3 mg buprenorphine, respectively. Necessary vitals were monitored and recorded. Visual analog scale (VAS) and verbal rating scale (VRS) scores were recorded and analyzed systematically. Statistical Analysis Used: All observations were analyzed using analysis of variance and Student's t-test. Results: The mean pain scores were highest in Group A compared to Group B and Group C. Mean VAS and VRS scores were highest in Group C comparatively and lowest in Group A. Conclusion: Combination of buprenorphine and bupivacaine intraperitoneally is comparatively more effective in relieving postoperative pain in comparison to intraperitoneal instillation of bupivacaine alone for postoperative pain management after laparoscopic cholecystectomy.

    Transanal endoscopic microsurgery (TEM) is a minimally invasive technique for local excision of benign and malignant neoplasms in the rectum. Indications for this technique are constantly changing and extending. The aim of this study is to describe a case of a unique and innovative application of this surgical technique. A 72-year-old patient was admitted to the Clinical Department of General and Colorectal Surgery for elective resection of a tumor located in the perianal area using the TEM surgical technique. In August 2005 the patient underwent laparoscopic cholecystectomy due to symptomatic cholecystitis. From March 2011 the patient complained about ongoing sharp pain in the perianal and presacral area. Computed tomography revealed two oval areas approximately 30 mm in size to the right of the sigmoido-rectal region communicating with the colon lumen. Subsequently diverticulitis was diagnosed. The TEM technique was uniquely used to successfully remove the gallstone from the 72-year-old patient's presacral area. PMID:26865896

    Acute acalculous cholecystitis (ACC) is most frequently reported in critically ill patients following sepsis, extensive injury or surgery. It is rather uncommon as a chemotherapy-induced complication, which is usually life-threatening in neutropenic patients subjected to myelosuppressive therapy. A 23-year-old patient with acute lymphoblastic leukemia was subjected to myelosuppressive chemotherapy (cyclophosphamide, cytarabine, pegaspargase). After the first chemotherapy cycle the patient was neutropenic and feverish; she presented with vomiting and pain in the right epigastrium. Ultrasound demonstrated an acalculous gallbladder with wall thickening up to 14 mm. The ACC was diagnosed. Medical therapy included a broad spectrum antibiotic regimen and granulocyte-colony stimulating factors. On the second day after ACC diagnosis the patient's general condition worsened. Laparoscopic cholecystectomy was performed. The resected gallbladder showed no signs of bacterial or leukemic infiltrates. The postoperative course was uneventful. In the management of neutropenic patients with ACC surgical treatment is as important as pharmacological therapy. PMID:25337176

    In this paper, we report a case of drug-induced pancreatitis just after taking a pain pill including a low-dose combination of acetaminophen and codeine. Codeine-induced pancreatitis has been rarely reported, however, well-established. The proposed mechanism for codeine-induced pancreatitis is by increasing Oddi sphincter pressure. However, the clinically important point is that the codeine-induced pancreatitis is seen almost only in the cholecystectomized patients due to lacking of its reservoir capacity. Codeine is commonly used alone or in combination in pain medicine. Therefore, it is fairly important to question whether a patient underwent cholecystectomy when a physician decides to prescribe codeine-included preparations. PMID:26157656

    Results of examination and surgical tratment of 56 patients, suffering chronic calculous cholecystitis with concomitant schemic heart disease, were analyzed. In all the patients a laparoscopic cholecystectomy was performed. Monitoring of cardiovascular compli- cations was estimated with the help of a Helter recording of EGG intraoperatively and in the early postoperative period. Depending on a kind of preoperative preparation done, the patients were divided on two groups: those, to whom cardioprotection using a Vasopro preparation was conducted, and those without cardioprotection. Depending on the intraoperative pneumoperitoneum regime used in every group two subgroups were delineated: in intraabdominal pressure 5-7.9 mm Hg and 8-10 mm Hg. In the patients, to whom cardioprotection was conducted and operative intervention in a carboxyperitoneum regime performed while intraabdominal pressure 5-7.9 mm Hg, a frequency of cardiovascular complications was lesser than in a control group.

    INTRODUCTION Robotic single-site surgery (RSS) represents the latest innovation for clinical use of single incision surgery. Several applications have been reported in urology, general surgery and gynecology with potential application in benign cases as well as in oncology. PRESENTATION OF CASE To further explore potential applications of RSS, we present the first case reported in the literature of combined cholecystectomy and total hysterectomy using the da Vinci Si single-port platform (Intuitive Surgical Inc., Sunnyvale, CA). DISCUSSION A critical description of the procedure with potential advantages and limitations of the current platform for combined surgical procedure is provided. CONCLUSION Robotics may facilitate the widespread diffusion of single incision surgery, overcoming current laparoscopic and LESS limitations. However, the available robotic platform still has technical features that will limit its uptake amongst surgeons and further technological development is needed for a wider diffusion of single incision surgery.

    Cholescintigraphy using technetium-99m disofenin tracer is accepted as a routine component of preoperative evaluation of the biliary tract in selected patients but is not used regularly in postoperative management. This is a retrospective analysis of the utility of the nuclide scan in 27 patients after laparoscopic cholecystectomy (LC). Most patients had vague postoperative symptoms such as nausea, pain, and low grade fever. Two patients developed jaundice. Seven of the 27 patients had biliary leaks, and two had common bile duct obstructions. We conclude that cholescintigraphy is a sensitive noninvasive test for the evaluation of biliary complications after LC and is a pivotal component of an algorithmic approach to postoperative complications. Because of the subtle clinical findings and the potential for delayed diagnosis of biliary complications after LC, early performance of this test will minimize patient morbidity. PMID:8116979

    Up to now, emerging contaminants have not been further-studied in in-situ stormwater best management practices and especially in detention basins. In this article, the efficiency of a dry stormwater detention basin was investigated regarding the removal of 7 alkylphenols and alkylphenol ethoxylates, 9 polybrominated diphenyl ethers, 45 pesticides and bisphenol A. Concentrations of contaminants were obtained by chemical analysis on dissolved and particulate phase distinctly. The removal efficiency was assessed on total, dissolved and particulate phase accounting for the global chain of uncertainty with a 95% confidence interval. Results showed that pesticides (rather hydrophilic) are not trapped in the detention basin but are released contrarily to B209 which is mostly in particulate phase. Alkylphenols and alkylphenol ethoxylates are present in both phases and the efficiency is storm event-dependent. Uncertainty consideration in efficiency determination revealed efficiency data, usually presented by raw values are not relevant to conclude on the performance of a detention basin. In this case study, efficiency data with a 95% confidence interval indicate that only 35%, 50% and 41% of campaigns showed an impact (in trapping or releasing) of the detention basin on alkylphenols and ethoxylates, polybrominated diphenyl ethers and pesticides respectively.

    Background Use of transversus abdominis plane (TAP) block for postoperative analgesia is continuously increasing. However, few studies have investigated intraoperative effects of TAP block. We aimed to study the effects of TAP block in terms of cost-effectiveness and consumption of inhalation agents. Material/Methods Forty patients undergoing laparoscopic cholecystectomy were enrolled in this study. Patients were randomly divided into 2 groups: Group 1 (n=20) patients received TAP block and Group 2 (n=20) patients did not receive TAP block. Standard anesthesia induction was used in all patients. For the maintenance of anesthesia, fractional inspired oxygen (FIO2) of 50% in air with desflurane was used with a fresh gas flow of 4 L/min. All patients were monitored with electrocardiography and for peripheral oxygen saturation (SpO2), end-tidal carbon dioxide (ET), heart rate (HR), noninvasive mean blood pressure (MBP), and bispectral index (BIS). Bilateral TAP blocks were performed under ultrasound guidance to Group 1 patients. The BIS value was maintained at between 40 and 50 during the surgery. The Dion formula was used to calculate consumption of desflurane for each patient. Results There was no difference between the groups with respect to demographic characteristics of the patients. Duration of anesthesia, surgery time, and dosage of fentanyl were similar in the 2 groups. However, the cost and consumption of desflurane was significantly lower in Group 1. Conclusions Total anesthesia consumption was lower and the cost-effectiveness of anesthesia was better in TAP block patients with general anesthesia than in non-TAP block patients undergoing laparoscopic cholecystectomy.

Moreover, the influencing factors of SILC were analyzed. Methods: A total of 552 patients with symptomatic gallstones or polyps were allocated randomly to undergo SILC (n = 138) or TLC (n = 414). Data on postoperative pain score, operative time, complications, procedure conversion, and hospital costs were collected. After a 6-month follow-up, all data were analyzed using the intention-to-treat principle. Results: Among SILC group, 4 (2.9%) cases required conversion to TLC. Mean operative time of SILC was significantly longer than that of TLC (58.97 ± 21.56 vs. 43.38 ± 19.02 min, P < 0.001). The two groups showed no significant differences in analgesic dose, duration of hospital stay, or cost. Median pain scores were similar between the two groups 7 days after surgery, but SILC-treated patients had a significantly lower median pain score 6 h after surgery (10-point scale: 3 [2, 4] vs. 4 [3, 5], P = 0.009). Importantly, subgroup analyses of operative time for SILC showed that a longer operative time was associated with greater prevalence of pain score >5 (≥100 min: 5/7 patients vs. <40 min, 3/16 patients, P = 0.015). Conclusions: The primary benefit of SILC appears to be slightly less pain immediately after surgery. Surgeon training seems to be important because the shorter operative time for SILC may elicit less pain immediately after surgery. PMID:26668145

    Purpose We performed 3-channel single incision laparoscopic cholecystectomy (SILC) in earlier period of this study and modified our method to 4-channel SILC using a snake retractor for better operative field in later period. This study has been designed to evaluate the risk factors for prolonged operative time in SILC. Methods From April 2010 to August 2014, 323 cases of 3-channel SILC (Konyang standard method [KSM] group) and 399 cases of 4-channel SILC (modified KSM [mKSM] group) using a snake retractor were performed. Results The clinical characteristics were not significantly different between KSM and mKSM group except preoperative percutaneous transhepatic gallbladder drainage (PTGBD) treatment (9.6% vs. 16.5%, P < 0.007). The mean operation time was longer in mKSM group than KSM group (55.8 ± 19.7 minutes vs. 51.7 ± 20.1 minutes, P = 0.006). The estimated blood loss of KSM group was more than mKSM group (24.6 ± 54.1 mL vs. 16.9 ± 27.0 mL, P = 0.013). According to the histopathologic findings, acute cholecystitis or empyema were confirmed more in mKSM group as compared with KSM group (28% vs. 14.0%, P = 0.025). In multivariate analysis, the risk factors for prolonged operation time were drainage insertion, histopathologic findings (acute cholecystitis or empyema), surgeons' technical expertise, body mass index > 30 kg/m2 as well as the 4-channel SILC. Conclusion Among patients with these risk factors, conventional laparoscopic cholecystectomy could be considered as well although SILC might be safe and feasible modality for benign gallbladder disease.

    The laparoscopic cholecystectomy (LC) is an important approach of treating acute cholecystitis and the timing of performing this given treatment is associated with clinical outcomes. Although several meta-analyses have been done to investigate the optimal timing of implementing this treatment, the conflicting findings from these meta-analyses still confuse decision-making. And thus, we performed this systematic review to assess discordant meta-analyses and generate conclusive findings to facilitate informed decision-making in clinical context eventually. We electronically searched the PubMed, Cochrane Library, and EMBASE to include meta-analysis comparing early (within 7 days of the onset of symptoms) with delayed LC (at least 1 week after initial conservative treatment) for acute cholecystitis through August 2015. Two independent investigators completed all tasks including scanning and appraising eligibility, abstracting essential information using prespecified extraction form, assessing methodological quality using Oxford Levels of Evidence and Assessment of Multiple Systematic Reviews (AMSTAR) tool, and assessing the reporting quality using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), as well as implementing Jadad algorithm in each step for the whole process. A heterogeneity degree of ≤50% is accepted. Seven eligible meta-analyses were included eventually. Only one was Level I of evidence and remaining studies were Level II of evidence. The AMSTAR scores varied from 8 to 11 with a median of 9. The PRISMA scores varied from 19 to 26. The most heterogeneity level fell into the desired criteria. After implementing Jadad algorithm, 2 meta-analyses with more eligible RCTs were selected based on search strategies and implication of selection. The best available evidence indicated a nonsignificant difference in mortality, bile duct injury, bile leakage, overall complications, and conversion to open surgery, but a significant reduction

    Due to high mortality associated with aortic dissection, anesthetic management of patients with Marfan syndrome with severe aortic root dilation is a challenging situation. We describe the anesthetic management of a patient with Marfan syndrome with severe aortic root dilation, who required major surgery like cholecystectomy with partial liver resection under general anesthesia. A 47-year-old female presented to pre-anesthetic clinic for cholecystectomy with partial hepatic resection for gall bladder carcinoma. Clinical features, transthoracic echocardiography and computed tomography of thorax supported a diagnosis of Marfan syndrome with severely dilated aortic root. Aortic dissection in patients with Marfan syndrome and severely dilated aortic root can be precipitated by major hemodynamic changes under anesthesia. Careful hemodynamic monitoring and avoidance of hemodynamic swings can prevent this life-threatening event. PMID:24348301

    Objective: For cholecystectomy, both the needlescopic cholecystectomy (NC) 3-trocar technique using 2 to 3 mm trocars and the umbilical-assisted transvaginal cholecystectomy (TVC) technique have found their way into clinical routine. This study compares these 2 techniques in female patients who are in need of an elective cholecystectomy. Background: Natural orifice transluminal endoscopic surgery (NOTES) is a surgical concept permitting scarless intra-abdominal operations through natural orifices, such as the vagina. Because of the lack of an adequately powered trial, we designed this first randomized controlled study for the comparison of TVC and NC. Methods: This prospective, randomized, nonblinded, single-center trial evaluates the safety and effectiveness of TVC (intervention), compared with NC (control) in female patients with symptomatic cholecystolithiasis. The primary endpoint was intensity of pain until the morning of postoperative day (POD) 2. Secondary outcomes were among others intra- and postoperative complications, procedural time, amount of analgesics used, pain intensity until POD 10, duration of hospital stay, satisfaction with the aesthetic result, and quality of life on POD 10 as quantified with the Eypasch Gastrointestinal Quality of Life Index (GIQLI). Results: Between February 2010 and June 2012, 40 patients were randomly assigned to the interventional or control group. All patients completed follow-up. Procedural time, length of postoperative hospital stay, and the rate of intra- and postoperative complications were similar in the 2 groups. However, significant advantages were found for the transvaginal access regarding pain until POD 2, but also until POD 10 (P = 0.043 vs P = 0.010) despite significantly less use of peripheral analgesics (P = 0.019). In the TVC group, patients were significantly more satisfied with the aesthetic result (P < 0.001) and had a significantly better GIQLI (P = 0.028). Conclusions: Although comparable in terms of

    Objectives: Incidence of postoperative nausea and vomiting (PONV), without active intervention, following laparoscopic cholecystectomy is unacceptably high. We evaluated the effectiveness of intravenous (IV) palonosetron in counteracting PONV during the first 24hrs following laparoscopic cholecystectomy, using ondansetron as the comparator drug. Materials and Methods: In a randomized, controlled, single blind, parallel group trial, single pre-induction IV doses of palonosetron (75mcg) or ondansetron (4mg) were administered to adult patients of either sex undergoing elective laparoscopic cholecystectomy. There were 49 subjects per group. The pre-anesthetic regimen, anesthesia procedure and laparoscopic technique were uniform. The primary effectiveness measure was total number of PONV episodes in the 24 hrs period following end of surgery. The frequencies of individual nausea, retching and vomiting episodes, visual analog scale (VAS) score for nausea at 2, 6 and 24hrs, use of rescue antiemetic (metoclopramide), number of complete responders (no PONV or use of rescue in 24 hrs) and adverse events were secondary measures. Results: There was no statistically significant difference between the groups in primary outcome. Similarly, the frequencies of nausea, retching and vomiting episodes, when considered individually, did not show significant difference. Nausea score was comparable at all time points. With palonosetron, 14 subjects (28.6%) required rescue medication while 13 (26.5%) did so with ondansetron. The number of complete responders was 14 (28.6%) and 16 (32.7%), respectively. Adverse events were few and mild. QTc prolongation was not encountered. Conclusion: Palonosetron is comparable to ondansetron for PONV prophylaxis in elective laparoscopic cholecystectomy when administered as single pre-induction dose. PMID:23543732

    Introduction Cholecystectomy for benign gallbladder diseases can lead to previously undiagnosed gallbladder cancer during histopathological evaluation. Despite some controversy over its usefulness, histopathological evaluation of all gallbladder specimens is common in most hospitals. We evaluated the results of routine pathology of the gallbladder after cholecystectomy for benign gallbladder diseases with regard to unexpected primary gallbladder cancer (UPGC). Methods Patients undergoing cholecystectomy because of benign gallbladder diseases between 2009 and 2013 were enrolled in this study. All gallbladder specimens were sent to the pathology department, and histopathological reports were examined in detail. The impact of demographic features on pathological diagnoses and prevalence of UPGC assessed. Data on additional interventions and postoperative survival for patients with UPGC were collected. Results We enrolled 1,747 patients (mean age, 48.7±13.6 years). Chronic cholecystitis was the most common diagnosis (96.3%) and was associated significantly with being female (p=0.001). Four patients had UPGC (0.23%); one was stage T3 at the time of surgery, and the remaining three cases were stage T2. Conclusions Routine histopathological examination of the gallbladder is valuable for identification of cancer that requires further postoperative management. PMID:26924485

    Surgical bile duct injury (SBDI), during laparoscopic cholecystectomy, is a worldwide ongoing problem. The purpose of this study is to analyze a single center retrospective experience with this topic. From 1999 to 2012, 30 patients with diagnosis of SBDI after laparoscopic cholecystectomy performed in other institute for gallbladder lithiasis and then transferred to our facility were enrolled in this analysis. We considered in the study the following parameters: classification and site of the bile duct injury, infective complications and therapeutic management according to early or late referral. Twenty four patients (80 %) had a SBDI type E1; a concomitant vascular injury was described in 3/30 (10 %) in right hepatic artery. 11 patients had HJJ as primary surgical treatment in our hospital. Surgical site infection was documented in 9/30 (30 %). The most common micro-organisms documented in SSI were E. coli with an incidence of 55.5 % of SSI. Worse infective complications were detected in the late referral group. Complex SBDI occurred during laparoscopic cholecystectomy should be early referred to advanced hepatobiliary program, for appropriate multidisciplinary management. PMID:26961379

    Biliary diseases known since ages constitute major portion of digestive tract disorders world over. Among these cholelithiasis being the fore runner causing general ill health, thereby requiring surgical intervention for total cure. The study was undertaken in an attempt to compare the hemodynamic changes in patient undergoing laparoscopic cholecystectomy using different intra-abdominal pressures created due to carbon dioxide insufflation. The patients were randomly allocated to one of the three groups in which different levels of intra-abdominal pressures (8-10 mmHg,11-13 mmHg and 14 mmHg and above) were maintained. The base line parameters monitored were heart rate, non invasive blood pressur(systolic and mean)and end tidal carbon dioxide. All the parameters were monitored at various intervals i.e. Immediately during insufflation, 5 min, 10 min, 20 min, 30 min after CO2 insufflation and after every 10 min if surgery exceeds 30 min, at exsufflation,10 min after CO2 exsufflation. Patients were ventilated with Pedius Drager Ventilator keeping tidal volume 8-10 ml/kg and respiratory rate 12-14 breaths/min. During surgery patients were placed in reverse Trendlenburg position (head up) at 15 °. The results obtained were evaluated statistically and analyzed. Baseline characteristics were found to be comparable. Hemodynamic variables were reported as mean and standard deviation. Statistical significance among groups was evaluated using Analysis of Variance and unpaired student t test (two tailed). Inter-group comparisons were made using Bonferroni test. A p-value of <0.05 was considered as statistically significant. In all the three groups the mean heart rate (baseline 84.08 ± 12.50, 87.96 ± 15.73 and 86.92 ± 17.00 respectively) increased during CO2 insufflation and the rise in heart rate continued till exsufflation after which it decreased and at 10 min after exsufflation the heart rates were comparable with the baseline.

    Introduction. We report the management of a septic Open Abdomen (OA) patient by the help of negative pressure therapy (NPT) and abdominal reapproximation anchor (ABRA) system in pregnant woman with spontaneous jejunal perforation after emergent cesarean section (C/S) with confounding factor of mild acute pancreatitis (AP). Presentation of Case. A 29-year-old and 34-week pregnant woman with AP underwent C/S. She was arrested after anesthesia induction and responded to cardiopulmonary resuscitation (CPR). There were only ash-colored serosanguinous fluid within abdomen during C/S. After C/S, she was transferred to intensive care unit (ICU) with vasopressor support. On postoperative 1st day, she underwent reoperation due to fecal fluid coming near the drainage. Leakage point could not be identified exactly and operation had to be deliberately abbreviated due to hemodynamic instability. NPT was applied. Two days later source control was provided by conversion of enteroatmospheric fistula (EAF) to jejunostomy. ABRA was added and OA was closed. No hernia developed at 10-month follow-up period. Conclusion. NPT application in septic OA patient may gain time to patient until adequate source control could be achieved. Using ABRA in conjunction with NPT increases the fascial closure rate in infected OA patient. PMID:27006853

    PubMed Central

    2012-01-01

    Background Cholecystectomy, gold standard treatment for gallbladder lithiasis, is closely associated with increased bile reflux into the stomach as amply demonstrated by experimental studies. The high prevalence of gallstones in the population and the consequent widespread use of surgical removal of the gallbladder require an assessment of the relationship between cholecystectomy and gastric mucosal disorders. Morphological evaluations performed on serial pre and post – surgical biopsies have provided new acquisitions about gastric damage induced by bile in the organ. Methods 62 elderly patients with gallstone related disease were recruited in a 30 months period. All patients were subjected to the most appropriate treatment (Laparoscopic cholecystectomy). The subjects had a pre-surgical evaluation with: • dyspeptic symptoms questionnaire, • gastric endoscopy with body, antrum, and fundus random biopsies, • histo-pathological analysis of samples and elaboration of bile reflux index (BRI). The same evaluation was repeated at a 6 months follow-up. Results In our series the duodeno-gastric reflux and the consensual biliary gastritis, assessed histologically with the BRI, was found in 58% of the patients after 6 months from cholecystectomy. The demonstrated bile reflux had no effect on H. pylori’s gastric colonization nor on the induction of gastric precancerous lesions. Conclusions Cholecystectomy, gold standard treatment for gallstone-related diseases, is practiced in a high percentage of patients with this condition. Such procedure, considered by many harmless, was, in our study, associated with a significant risk of developing biliary gastritis after 6 months during the postoperative period. PMID:23173777

    Single-incision laparoscopic cholecystectomy (SILC) has been shown to be safe in children; however, factors that impact outcomes are not well understood. We report a retrospective review of 151 patients who underwent SILC between 2009 and 2013. Regression analysis was used to determine inflection of learning curve. Patients were grouped by early cases, late cases, and late case with surgical trainees. Mean age for all patients was 15 ± 3 years (5-20.5 year), and mean weight was 66.5 ± 21.3 kg (15-117 kg). There was a decrease in operative times between the early group (n = 15) and the late group (n = 100) (75.3 vs 56.1 minutes, P < 0.05). Surgical trainees were involved in 36 cases, and their introduction did not significantly increase operative times (56.1 vs 60.4 minutes, P = NS (Non-significant)). No difference in operative times between early cases and cases with trainees was identified (75.3 vs 60.4 minutes, P = NS). The complication was 6 per cent, with no significant differences between the groups. There were five conversions (3.3%). During the adoption of SILC, significantly decreased operative times were achieved after a short learning curve, and these were maintained with surgical trainees. Our results show that SILC can be safely introduced into a pediatric surgical practice. PMID:26350657

    Purpose Laparoscopic cholecystectomy (LC) has become a standard treatment of symptomatic gallstone disease. But, some patients suffer from retained common bile duct stones after LC. The aim of this study is to analyze the predicting factors associated with subsequent postoperative endoscopic retrograde cholangiopancreatography (ERCP) after LC. Methods We retrospectively reviewed a database of every LC performed between July 2006 and September 2012. We classify 28 patients who underwent ERCP within 6 months after LC for symptomatic gallstone disease as the ERCP group and 56 patients who underwent LC for symptomatic gallstone disease during same period paired by sex, age, underlying disease, operation history, and body mass index as the control group. To identify risk factor performing postoperative ERCP after LC, we compared admission route, preoperative biochemical liver function test, number of gall stones, gallstone size, adhesion around GB, wall thickening of GB, and existence of acute cholecystitis between the 2 groups. Results Admission route, preoperative AST, ALT, and ALP, stone size, longer operation time, and acute cholecystitis were identified as risk factors of postoperative ERCP in univariate analyses. But, longer operation time (P = 0.004) and acute cholecystitis (P = 0.048) were identified as independent risk factors of postoperative ERCP in multivariate analyses. Conclusion The patient who underwent ERCP after LC for symptomatic gallstone disease are more likely experienced longer operation time and acute cholecystitis than the patient who did not undergo ERCP after LC.

    There are a variety of procedures to use once a common bile duct stone is discovered at the time of cholecystectomy. To be cost-effective, the surgeon must know how much money will be spent with each procedure chosen. Cost data is largely unavailable because costs are difficult to estimate and charge data are jealously guarded. In addition, costs are not the same at different hospitals and therefore cannot be compared. The factors that increase costs for treating bile duct stones are outlined in this report and real costs are used from one hospital to help with illustration. Surgical costs vary with the severity of the disease, the amount of operating room time required, and length of stay. These surgical costs can be avoided by choosing endoscopic retrograde cholangiopancreatography, but the new costs increase almost twice that of a successful laparoscopic common bile duct exploration. Knowledge of the pattern of choledocholithiasis, the varieties of treatment, the cost implications, and the outcomes of each are the subject of this report. PMID:11323767

    Wound infusion with local anesthetics has been used for postoperative pain relief with variable results. This randomized, controlled, double-blind clinical trial examines the effect of ropivacaine infusion on pain after laparoscopic cholecystectomy. A total of 110 patients were randomly assigned to 2 groups. After induction of anesthesia a 75-mm catheter was inserted subcutaneously and connected to an elastomeric pump containing either 0.75% ropivacaine (ropivacaine group) or normal saline (control group) for 24 hours postoperatively. Before skin closure, each hole was infiltrated with 2 mL of 0.75% ropivacaine or normal saline according to randomization. Pain at rest, pain during cough, and analgesic consumption were recorded in the postanesthesia care unit and at 2, 4, 8, 24, and 48 hours postoperatively. Analgesic requirements and pain scores were recorded 1 and 3 months after surgery. The ropivacaine group reported less pain during cough (P=0.044) in the postanesthesia care unit (P=0.017) and 4 hours postoperatively (P=0.038). Ropivacaine wound infusion had no effect on late and chronic pain. PMID:26679680

    Background. Concomitant vascular injury might adversely impact outcomes after iatrogenic bile duct injury (IBDI). Whether a new HPB center should embark upon repair of complex biliary injuries with associated vascular injuries during learning curve is unknown. The objective of this study was to determine outcome of surgical management of IBDI with and without vascular injuries in a new HPB center during its learning curve. Methods. We retrospectively reviewed patients who underwent surgical management of IBDI at our center. A total of 39 patients were included. Patients without (Group 1) and with vascular injuries (Group 2) were compared. Outcome was defined as 90-day morbidity and mortality. Results. Median age was 39 (20–80) years. There were 10 (25.6%) vascular injuries. E2 injuries were associated significantly with high frequency of vascular injuries (66% versus 15.1%) (P = 0.01). Right hepatectomy was performed in three patients. Out of these, two had a right hepatic duct stricture and one patient had combined right arterial and portal venous injury. The number of patients who developed postoperative complications was not significantly different between the two groups (11.1% versus 23.4%) (P = 0.6). Conclusion. Learning curve is not a negative prognostic variable in the surgical management of iatrogenic vasculobiliary injuries after cholecystectomy. PMID:27525124

    Removal of the gallbladder is thought to increase formation and pool size of secondary bile acids, mainly deoxycholic acid (DCA), by increased exposure of primary bile acids (cholic acid [CA], chenodeoxycholic acid [CDCA]) to bacterial dehydroxylation in the intestine. We have tested this hypothesis by simultaneous determination of pool size and turnover of DCA, CA, and CDCA in nine women before and at various intervals after removal of a functioning gallbladder. An isotope dilution technique using marker bile acids labeled with stable isotopes (2H4-DCA, 13C-CA, 13C-CDCA) was used. After cholecystectomy, concentration and output of bile acids relative to bilirubin increased (P less than 0.02) in fasting duodenal bile and cholesterol saturation decreased by 27% (P less than 0.05) consistent with enhanced enterohepatic cycling of bile acids. Three months after removal of the gallbladder bile acid kinetics were in a new steady state: pool size and turnover of CDCA were unchanged. Synthesis of CA, the precursor of DCA, was diminished by 37% (P = 0.05), probably resulting from feedback inhibition by continuous transhepatic flux of bile acids. The fraction of CA transferred after 7 alpha-dehydroxylation to the DCA pool increased from 46 +/- 16 to 66 +/- 32% (P less than 0.05). However, this enhanced transfer did not lead to increased input or size of the DCA pool, because synthesis of the precursor CA had decreased. PMID:2708522

    Purpose: To report our experience in the use of percutaneous extraction of common bile duct stones detected in the post-cholecystectomy period. Methods: Forty-two patients in whom endoscopic cannulation and/or sphincterotomy had failed or could not be done due to several reasons underwent balloon dilatation of the ampulla of Vater and subsequent advancement of the stones via the percutaneous transhepatic route or T-tube tract. Results: The procedure was successful in 42 cases. In three patients, stones were crushed in the common bile duct and pushed as fragments into the duodenum. In all cases transient adverse effects were observed. There were no major complications. All cases were checked with ultrasonography for 6 months after the procedure. Conclusion: Percutaneous extraction of common bile duct stones is an effective method of treatment with a high success rate,low complication rate and shorter hospital stay. It may serve as an alternative method in cases where endoscopic removal of stones fails.

    AIM: To compare the characteristics of two single-incision methods, and conventional laparoscopy in cholecystectomy, and demonstrate the safety and feasibility. METHODS: Three hundred patients with gallstones or gallbladder polyps were admitted to two clinical centers from January 2013 to January 2014 and were randomized into three groups of 100: single-incision three-device group, X-Cone group, and conventional group. The operative time, intraoperative blood loss, complications, postoperative pain, cosmetic score, length of hospitalization, and hospital costs were compared, with a follow-up duration of 1 mo. RESULTS: A total of 142 males (47%) and 158 females (53%) were enrolled in this study. The population characteristics of these three groups is no significant differences exist in terms of age, sex, body mass index and American Society of Anesthesiology (P > 0.05). In results, there were no significant differences in blood loss, length of hospitalization, postoperative complications.The operative time in X-Cone group was significantly longer than other groups.There were significant differences in postoperative pain scores and cosmetic scores at diffent times after surgery (P < 0.05). CONCLUSION: This study shows that this two single-incision methods are safe and feasible. Both methods are superior to the conventional procedure in cosmetic and pain scores. PMID:25992193

    Postoperative pain is the main obstacle for safely rapid recovery of patients undergoing laparoscopic cholecystectomy (LC). In this study, we systemically evaluated the analgesic efficacy of intraperitoneal and incisional ropivacaine injected at the end of the LC. A total of 160 patients, scheduled for elective LC, were allocated into four groups. Group Sham received intraperitoneal and incisional normal saline (NS). Group IC received incisional ropivacaine and intraperitoneal NS. Group IP received incisional NS and intraperitoneal ropivacaine. Group ICP received intraperitoneal and incisional ropivacaine. At the end of the surgery, ropivacaine was injected into the surgical bed through the right subcostal port and infiltrated at the four ports. Dynamic pain by a visual analogue scale (VAS) and cumulative morphine consumption at 2 h, 6 h, 24 h, and 48 h postoperatively, as well as incidence of side-effects over 48 h after LC was recorded. Compared with those in group Sham, the time of post-anesthesia care unit (PACU) stay, dynamic VAS score (VAS-D) 2 h and 6 h postoperatively, cumulative morphine consumption 6 h and 24 h postoperatively, and incidence of nausea and vomiting 48 h after LC in group IC and ICP were less (P<0.05). Furthermore, intraperitoneal and incisional ropivacaine exerts more powerful analgesic effect than single usage with intraperitoneal or incisional ropivacaine (P<0.05). No patients exhibited signs of local anesthetic toxicity. In conclusion, intraperitoneal and incisional ropivacaine might facilitate PACU transfer and effectively and safely reduce pain intensity after LC. PMID:26885228

    Introduction Symptomatic hepatic-artery pseudoaneurysm (HAP) after bile-duct injury (BDI) is a rare complication with a varied (but clinically urgent) presentation. Methods A prospectively maintained database of all patients with BDI at laparoscopic cholecystectomy (LC) referred to a tertiary specialist hepatobiliary centre between 1992 and 2011 was searched systematically to identify patients with a symptomatic HAP. Care and outcome of these patients was studied. Results Eight (6 men) of 236 patients with BDI (3.4%) with a median age of 65 (range: 54?6) years presented with symptomatic HAP. Median time of presentation of the HAP from the index LC was 31 (range: 13?16) days. Bleeding was the dominant presentation in 7 patients. One patient presented late (>2 years) with abdominal pain alone. Computed tomography angiography was the most useful investigation. Angioembolisation was successful in 7 patients. One patient died, and another patient developed liver infarction. Three patients (38%) developed biliary strictures after embolisation. Seven patients are alive and well at a median follow-up of 66 months. Conclusions Presentation of HAP is often delayed. A high index of suspicion is necessary for the diagnosis. Computed tomography angiography is the first-line investigation and selective angioembolisation can yield successful outcomes. PMID:27580308

    Objectives Prevalences of bile duct injury (BDI) following laparoscopic cholecystectomy (LC) remain unacceptably high. There is no standardized method for performing an LC. This study aims to describe a standardized technique for LC that will allow for the development of a concept LC checklist, the use of which, it is hoped, will decrease the prevalence of BDI. Methods A standardized method for LC was developed based on previously published expert analysis supplemented by video error analysis of operations in which BDI occurred. Established checklist methodology was then used to construct an LC-specific concept checklist. Results A five-step technique for the safe establishment of the critical view was created to guide the development of the checklist. The five steps are: (i) confirm the gallbladder lies in the hepatic principal plane and is retracted to the 10 o'clock position; (ii) confirm Hartmann's pouch is lifted up and toward the segment IV pedicle; (iii) identify Rouvière's sulcus; (iv) confirm the release of the posterior leaf of the peritoneum covering the hepatobiliary triangle, and (v) confirm the critical view with or without intraoperative cholangiography. Conclusions A standardized approach to LC would allow for the creation of an LC-specific checklist that has the potential to lower the prevalence of BDI. PMID:23961737

    Context: Alpha-2 (α2) adrenergic receptor agonists, clonidine and dexmedetomidine, are widely used as adjuvants during anesthesia for analgesic, sedative, sympatholytic, and cardiovascular stabilizing effects. Aims: We compared effects of clonidine and dexmedetomidine (as propofol adjuvants) on intra-operative hemodynamics, recovery time, and postoperative cognitive function impairment. Subjects and Methods: Forty-five American Society of Anesthesiologists I and II patients, scheduled for laparoscopic cholecystectomy were divided into three groups (n = 15). Group C patients received bolus of clonidine 3 μg/kg followed by a continuous infusion; Group D patients received dexemedetomidine 1 μg/kg and a continuous infusion; and Group P patients received a bolus of normal saline followed by an infusion. Intra-operative mean arterial pressure (MAP) and pulse rate (PR) were measured throughout the surgery. Bispectral index was maintained at 55 ± 5 by titrating propofol infusion rate. The time between the interruption of anesthesia and eye opening (recovery time) was measured. Cognitive function was assessed using short mental status questionnaire at 15, 30, 45, and 60 min postoperatively. Results: The sympathetic response to laryngoscopy and extubation on MAP and PR were significantly reduced with the use of clonidine and dexmedetomidine (P < 0.05). The recovery was delayed (P < 0.05) with both the drug combinations and it was more pronounced with dexmedetomidine (P < 0.05). Dexmedetomidine group showed cognitive impairment in a postoperative period lasting up to an hour. Conclusions: When co-administered with propofol, both clonidine, and dexmedetomidine attenuate sympathetic response to laryngoscopy and extubation but cause delay in the recovery from anesthesia. Dexmedetomidine causes impairment of postoperative cognitive functions. PMID:26229757

    Purpose: our study compared the effect of fentanyl alone with fentanyl plus intravenous Paracetamol for analgesic efficacy, opioid sparing effects, and opioid-related side effects after laparoscopic cholecystectomy. Materials and Methods: eighty patients undergoing laparoscopic cholecystectomy were randomized into two groups, who were given either an IV placebo or an IV injection of 1g paracetamol just before induction. Both groups received fentanyl during induction and IM diclofenac for pain relief every 8 hourly for 24 h after surgery. The postoperative pain relief was evaluated by a visual analog scale (VAS) and consumption of fentanyl as rescue analgesic in the postoperative period for 24 h after surgery was measured. The incidence of PONV and sedation scores was also measured in the postoperative period. Results: the mean VAS score in first and second hour after surgery was less in the group receiving IV Paracetamol (3.3±0.4* vs. 5.2±0.9; 3.1±0.4* vs. 4.3±0.3); the fentanyl consumption over first 24 h was also less in the group receiving IV paracetamol (50±14.9 vs. 150±25.8). The time requirement of first dose of rescue analgesic in the postoperative period was also significantly prolonged in the group receiving IV paracetamol (76±24.7 vs. 48±15.8). There was no difference in the sedation scores and in the incidence of PONV in the two groups. Conclusion: The study demonstrates the usefulness of intravenous paracetamol as pre-emptive analgesic in the treatment of postoperative pain after laparoscopic cholecystectomy. PMID:25885388

    Background: We aimed to compare hemodynamic and endocrine alterations caused by stress response due to Proseal laryngeal mask airway and endotracheal tube usage in laparoscopic cholecystectomy. Materials and Methods: Sixty-three ASA I-II patients scheduled for elective laparoscopic cholecystectomy were included in the study. Patients were randomly allocated into two groups of endotracheal tube and Proseal laryngeal mask airway. Standard general anaesthesia was performed in both groups with the same drugs in induction and maintenance of anaesthesia. After anaesthesia induction and 20 minutes after CO2 insufflations, venous blood samples were obtained for measuring adrenalin, noradrenalin, dopamine and cortisol levels. Hemodynamic and respiratory parameters were recorded at the 1st, 5th, 15th, 30th and 45th minutes after the insertion of airway devices. Results: No statistically significant differences in age, body mass index, gender, ASA physical status, and operation time were found between the groups (p > 0.05). Changes in hemodynamic and respiratory parameters were not statistically significant when compared between and within groups (p > 0.05). Although no statistically significant differences were observed between and within groups when adrenalin, noradrenalin and dopamine values were compared, serum cortisol levels after CO2 insufflation in PLMA group were significantly lower than the ETT group (p = 0.024). When serum cortisol levels were compared within groups, cortisol levels 20 minutes after CO2 insufflation were significantly higher (46.1 (9.5-175.7) and 27.0 (8.3-119.4) in the ETT and PLMA groups, respectively) than cortisol levels after anaesthesia induction (11.3 (2.8-92.5) and 16.6 (4.4-45.4) in the ETT and PLMA groups, respectively) in both groups (p = 0.001). Conclusion: PLMA usage is a suitable, effective and safe alternative to ETT in laparoscopic cholecystectomy patients with lower metabolic stress. PMID:23264788

    AIM: To evaluate transvaginal hybrid-NOTES cholecystectomy (TVC) during its clinical establishment and compare it with the traditional laparoscopic technique (LC). METHODS: The specific problems and benefits of TVC were reviewed using a registry analysis, a comparative cohort study and a randomized clinical trial. At first, feasibility, safety and specific complications of the TVC were analyzed based on the first 488 data sets of the German NOTES Registry (GNR). Hereafter, we compared the early postoperative results of our first 50 TVC-patients with those of 50 female LC-patients matched by age, BMI and ASA classification. The same cohort was contacted an average of two years later to evaluate long-term results concerning pain and satisfaction with the aesthetic results and the overall postoperative results as well as sexual intercourse by means of two domains of the German version of the Female Sexual Function Index (FSFI-d). Consequently, we performed a randomized clinical trial comparing 20 TVC-patients with 20 needlescopic/3-trocar cholecystectomies (NC) also concerning the early postoperative results as well as pain, satisfaction and quality of life by means of the Eypasch Gastrointestinal Quality of Life Index (GIQLI) in the later course. Finally, we discussed the results in accordance with other published studies. RESULTS: The complication (3.5%) and conversion rates (4.1%) for TVC were low in the GNR and comparable to those of the LC. Access related intraoperative complications included injuries to the bladder (n = 4; 0.8%) and bowel (n = 3; 0.6%). The study cohort revealed less postoperative pain after TVC comparing to the LC-patients on the day of surgery (NRS, 1.5/10 vs 3.1/10, P = 0.003), in the morning (NRS, 1.9/10 vs 2.8/10, P = 0.047) and in the evening (NRS, 1.1/10 vs 1.8/10, P = 0.025) of postoperative day (POD) one. The randomized clinical trial consistently found less cumulative pain until POD 2 (NRS, 8/40 vs 14/40, P = 0.043), as well as until

    2016-01-01

    Background: Reduction in central sensitization by gabapentinoids that include gabapentin and pregabalin may reduce acute postoperative pain. Aims: The aim of this study is to evaluate postoperative analgesic benefit and efficacy in patients administered with oral gabapentin or pregabalin as premedication for laparoscopic cholecystectomy under general anesthesia. Settings and Design: Randomized, prospective, and comparative study. Materials and Methods: In this study, recruited patients were randomly allocated in three groups. Groups A, B, and C received 2 capsules of B complex, 3 capsules of 300 mg gabapentin each, and 2 capsules of 75 mg pregabalin, respectively, each in 30 patients of each group, 1 h before induction of anesthesia. Postoperative efficacy among these three groups was compared with respect to increase in duration of analgesia, reduction in postoperative pain scores, total postoperative requirements of analgesics and side effects. Statistical Analysis: Mean and standard deviation were calculated. Test of analysis between two groups was done by t-test and among three groups by analysis of variance, and then P value was calculated. Results: Pregabalin and gabapentin group had lower visual analog scale (VAS) score (P < 0.05), prolonged timing of first rescue analgesic (4.67 ± 14.79 vs. 158 ± 13.10 vs. 343.16 ± 9.69) min, and less opioid consumption (169.87 ± 20.32 vs. 116.13 ± 14.08 vs. 64.67 ± 16.69) mg compared to placebo group. Between the gabapentinoids, pregabalin group had lower VAS score, prolonged timing of first rescue analgesic, and less opioids consumption than the gabapentin group. Conclusion: It is concluded in this study that pregabalin group had lower VAS score, prolonged timing of first rescue analgesic, and less opioids consumption than the gabapentin group. Both gabapentinoids had better postoperative analgesic profile than placebo. PMID:27212747

    This study compared virtual reality (VR) training with low cost-blended learning (BL) in a structured training program.Training of laparoscopic skills outside the operating room is mandatory to reduce operative times and risks.Laparoscopy-naïve medical students were randomized in 2 groups stratified for sex. The BL group (n = 42) used E-learning for laparoscopic cholecystectomy (LC) and practiced basic skills with box trainers. The VR group (n = 42) trained basic skills and LC on the LAP Mentor II (Simbionix, Cleveland, OH). Each group trained 3 × 4 hours followed by a knowledge test concerning LC. Blinded raters assessed the operative performance of cadaveric porcine LC using the Objective Structured Assessment of Technical Skills (OSATS). The LC was discontinued when it was not completed within 80 min. Students evaluated their training modality with questionnaires.The VR group completed the LC significantly faster and more often within 80 min than BL (45% v 21%, P = .02). The BL group scored higher than the VR group in the knowledge test (13.3 ± 1.3 vs 11.0 ± 1.7, P < 0.001). Both groups showed equal operative performance of LC in the OSATS score (49.4 ± 10.5 vs 49.7 ± 12.0, P = 0.90). Students generally liked training and felt well prepared for assisting in laparoscopic surgery. The efficiency of the training was judged higher by the VR group than by the BL group.VR and BL can both be applied for training the basics of LC. Multimodality training programs should be developed that combine the advantages of both approaches. PMID:25997044

    Background: The purpose of the present study was to determine the post-operative analgesic effects of preemptive intravenous (iv) paracetamol and the amount of reduction in tramadol (Contramal®) consumption. Materials and Methods: Following local research ethics committee approval, ASAI-II, 300 patients were assigned in a randomized manner into three groups: Group I (preemptive) received iv paracetamol 1 g/100 mL 10 min before skin inscision and 100 mL of saline solution at the end of the operation, Group II (post-operative) received 100 mL of saline solution 10 min before skin inscision and iv paracetamol 1 g/100 mL at the end of the operation and Group III (placebo) received 100 mL of saline solution 10 min before skin insicision and 100 mL of saline solution at the end of the operation as well. The time to first analgesic requirement use and 24 h total analgesic consumption were recorded. Visual analog scale (VAS) pain scores were obtained from all patients at 15, 30, min 1, 2, 4, 6, 8, 12 and 24 h after the end of the operation. Results: Time to first analgesic requirement was significantly longer in Group I and Group II, compared to Group III (P < 0.05). Time to first analgesic requirement was significantly longer in Group I compared to Group II (P < 0.05). Total analgesic consumption and postoperative VAS pain scores recorded were significantly lower in Group I and II, compared to Group III. Total analgesic consumption and postoperative VAS pain scores recorded were significantly lower in Group I compared to Group II (P < 0.05). Conclusion: In conclusion, preemptive iv paracetamol provided effective and reliable pain control after cholecystectomy surgeries and reduced post-operative pain scores, the need for and use of supplementary opioids and the time to first request of analgesics.

    Background Few studies of laparoscopic cholecystectomy (LC) outcome have used longitudinal data for more than two years. Moreover, no studies have considered group differences in factors other than outcome such as age and nonsurgical treatment. Additionally, almost all published articles agree that the essential issue of the internal validity (reproducibility) of the artificial neural network (ANN), support vector machine (SVM), Gaussian process regression (GPR) and multiple linear regression (MLR) models has not been adequately addressed. This study proposed to validate the use of these models for predicting quality of life (QOL) after LC and to compare the predictive capability of ANNs with that of SVM, GPR and MLR. Methodology/Principal Findings A total of 400 LC patients completed the SF-36 and the Gastrointestinal Quality of Life Index at baseline and at 2 years postoperatively. The criteria for evaluating the accuracy of the system models were mean square error (MSE) and mean absolute percentage error (MAPE). A global sensitivity analysis was also performed to assess the relative significance of input parameters in the system model and to rank the variables in order of importance. Compared to SVM, GPR and MLR models, the ANN model generally had smaller MSE and MAPE values in the training data set and test data set. Most ANN models had MAPE values ranging from 4.20% to 8.60%, and most had high prediction accuracy. The global sensitivity analysis also showed that preoperative functional status was the best parameter for predicting QOL after LC. Conclusions/Significance Compared with SVM, GPR and MLR models, the ANN model in this study was more accurate in predicting patient-reported QOL and had higher overall performance indices. Further studies of this model may consider the effect of a more detailed database that includes complications and clinical examination findings as well as more detailed outcome data. PMID:23284677

    Pain and diaphragmatic dysfunction are the major reasons for postoperative pulmonary complications after upper abdominal surgery. Preoperative administration of analgesics helps to reduce and prevent pain. The objective of this study was first to research the rate of pulmonary complications for laparoscopic cholecystectomy (LC) and then analyze the influence of preemptive analgesia on pulmonary functions and complications. Seventy patients scheduled for elective LC were included in our double-blind, randomized, placebo-controlled, prospective study. Randomly, 35 patients received 1 g etofenamate (group 1) and 35 patients 0.9% saline (group 2) intramuscularly 1 h before surgery. All patients underwent physical examination, chest radiography, lung function tests, and pulse oxygen saturation measurements 2 h before surgery and postoperatively on day 2. Atelectasis was graded as micro, focal, segmental, or lobar. With preemptive analgesia, the need for postoperative analgesia decreased significantly in group 1. In both groups mean spirometric values were reduced significantly after the operation, but the difference and proportional change according to preoperative recordings were found to be similar [29.5 vs. 31.3% reduction in forced vital capacity (FVC) and 32.9 vs. 33.5% reduction in forced expiratory volume in 1 s (FEV(1)) for groups 1 and 2, respectively]. There was an insignificant drop in oxygen saturation rates for both groups. The overall incidence of atelectasia was similar for group 1 and 2 (30.2 vs. 29.2%). Although the degree of atelectesia was found to be more severe in the placebo group, the difference was not statistically significant. We concluded that although preemptive analgesia decreased the need for postoperative analgesia, this had no effect on pulmonary functions and pulmonary complications. PMID:19117121

  16. Dissection by Ultrasonic Energy Versus Monopolar Electrosurgical Energy in Laparoscopic Cholecystectomy

    PubMed Central

    2010-01-01

    Introduction: Laparoscopic cholecystectomy is the gold standard for management of symptomatic gallstones. Electrocautery remains the main energy form used during laparoscopic dissection. However, due to its risks, search is continuous for safer and more efficient forms of energy. This review assesses the effects of dissection using ultrasonic energy compared with monopolar electrocautery during laparoscopic cholecystectomy. Methods: A literature search of the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE, and EMBASE was performed. Studies included were trials that prospectively randomized adult patients with symptomatic gallstone disease to either ultrasonic or monopolar electrocautery dissection during laparoscopic cholecystectomy. Data were collected regarding the characteristics and methodological quality of each trial. Outcome measures included operating time, gallbladder perforation rate, bleeding, bile leak, conversion rate, length of hospital stay and sick leave, postoperative pain and nausea scores, and influence on systemic immune and inflammatory responses. For metaanalysis, the statistical package RevMan version 4.2 was used. For continuous data, Weighted Mean Difference (WMD) was calculated with 95% confidence interval (CI) using the fixed effects model. For Categorical data, the Odds Ratio (OR) was calculated with 95% confidence interval using fixed effects model. Results: Seven trials were included in this review, with a total number of 695 patients randomized to 2 dissection methods: 340 in the electrocautery group and 355 in the ultrasonic group. No mortality was recorded in any of the trials. With ultrasonic dissection, operating time is significantly shorter in elective surgery (WMD −8.19, 95% CI −10.36 to −6.02, P>0.0001), acute cholecystitis (WMD −17, 95% CI −28.68 to −5.32, P=0.004), complicated cases (WMD −15, 95% CI −28.15 to −1.85, P=0.03), or if surgery was performed by trainee

    A 23-year-old male with one month of intractable vomiting, subsequent cholecystitis status post cholecystectomy, and overall 40-pound weight loss over the last few months presented with altered mental status and seizures. MRI showed signal abnormalities involving the hypothalamus, periaqueductal gray matter, 4th ventricle, and bilateral thalami, indicative of Wernicke's encephalopathy. The patient was started on empiric IV thiamine and methylprednisolone; thiamine levels were subsequently found to be low. Infectious disease workup was negative. Within a few days of this therapy, the patient's neurological status steadily improved with increased responsiveness and communication. Repeat MRI 7 days after admission showed significant resolution of the signal abnormalities. Over the next several weeks the patient became fully conversational, cognitively intact, and increasingly ambulatory. Nonalcoholic Wernicke's encephalopathy is rare; there have been reports relating it separately to vomiting and invasive surgery. In this case report, we associate it with both recurrent vomiting and minimally invasive cholecystectomy. We also discuss combinatorial therapy of thiamine and corticosteroids, which is poorly defined in the literature. Though there is no consensus-based optimal treatment of Wernicke's encephalopathy, this adds to the discussion of using dual therapy and supports that the use of empiric corticosteroids does not harm the patient.

    High intra-abdominal pressure and reverse Trendelenburg position during laparoscopic cholecystectomy (LC) are risk factors for venous stasis in lower extremity. Lower limb venous stasis is one of the major pathophysiological elements involved in the development of peri-operative deep vein thrombosis. Low pressure pneumoperitoneum (7-10 mmHg) has been recommended in patients with limited cardiac, pulmonary or renal reserve. The purpose of this study was to observe the effect of various pneumoperitoneum pressures on femoral vein (FV) hemodynamics during LC. A total of 50 patients undergoing elective LC were enrolled and they were prospectively randomized into two groups containing 25 patients each. In group A high pressure pneumoperitoneum (14 mmHg) and in group B low pressure pneumoperitoneum (8 mmHg) was maintained. Comparison of pre-operative and post-operative coagulation profile was done. Preoperative and intraoperative change in femoral vein diameter (FVD) (AP and LAT), cross-sectional area (CSA) and peak systolic flow (PSF) during varying pneumoperitoneum pressure was recorded in FV by ultrasound Doppler. First measurement (pre-operative) was carried out just after the induction of anesthesia before creation of pneumoperitoneum and second measurement (intra-operative) was taken just before completion of surgery with pneumoperitoneum maintained. Changes in coagulation parameters were less significant at low pressure pneumoperitoneum. There was statistical significant difference in the pre-operative and intra-operative values of FVD, CSA and PSF in both groups when analyzed independently (P = 0.00). There was no significant difference in pre-operative values of FVD, CSA and PSF (P > 0.05) among two groups but when the comparison was made between the intra-operative values, there was significant increase in FVD (AP) (P = 0.016), CSA (P = 0.00) and decrease in PSF (P = 0.00) at high pressure pneumoperitoneum.

    Background and Aims: Laparoscopic cholecystectomy is associated with a fairly high incidence of postoperative discomfort which is more of visceral origin than somatic. Studies have concluded that the instillation of local anesthetic with opioid around gall bladder bed provides more effective analgesia than either local anesthetic or opioid alone. Material and Methods: The study included 90 American Society of Anesthesiologists I-II patients of age 16-65 years scheduled for laparoscopic cholecystectomy under general anesthesia. The patients received the study drugs at the initiation of insufflation of CO2 in the intraperitoneal space by the operating surgeon under laparoscopic camera guidance over the gallbladder bed. Patients in Group T received tramadol 2 mg/kg in 30 ml normal saline, in Group B received bupivacaine 30 ml of 0.125% and in Group BT received tramadol 2 mg/kg in 30 ml of 0.125% bupivacaine intraperitoneally. Postoperative pain assessment was done at different time intervals in the first 24 h using Visual Analog Scale of 0-10 (0 = No pain, 10 = Worst pain imagined). Time to first dose of rescue analgesic and total analgesics required in the first 24 h postoperatively were also recorded. The incidence of side effects during the postoperative period was recorded. Results: Reduction in postoperative pain was elicited, at 4 and 8 h postoperatively when Group BT (bupivacaine-tramadol group) was compared with Group T (tramadol group) or Group B (bupivacaine group) (P < 0.01). There was a significantly lower requirement of analgesics during first 24 h postoperatively in Group BT compared to Group B or T but no significant difference in the intake of analgesics was noted between Groups B Group T. Time to first dose of rescue analgesic was also significantly prolonged in Group BT compared to Group B or T. The incidence of nausea and vomiting was comparable in all the study groups. Conclusions: Intraperitoneal application of bupivacaine with tramadol was a more

    Since the first silk suture material acting as a nidus for the development of subsequent common bile duct stones after cholecystectomy was described in 1897, several investigators have reported that suture materials may cause choledocholithiasis. Silk, chromic catgut, parasites, and other foreign bodies are known occasionally to form such niduses in the common bile duct. Surgical hemostatic clips have been used widely and generally are considered very safe. The first case of postcholecystectomy clip migration was reported in 1979. Its exact pathogenesis remains unknown; it generally is agreed that bile duct injuries, inappropriate clip placements, subclinical bile leak, and infections also have been postulated to contribute to clip migration. We report an unusual case in which the core of a biliary calculus in the common bile duct was found to contain a surgical clip. This case illustrates the potentially abrupt and late development of clip-related gallstones and highlights the need for long-term follow-up evaluation. PMID:21943951

    Background Laparoscopic cholecystectomy (LC) is one of the most common surgeries in laparoscopic surgery. Although, it is believed that LC has low-risk for post-operative infectious complications, the use of a prophylactic antibiotic is still controversial in elective LC. Objective To determine the impact of prophylactic antibiotics on postoperative infection complications in elective laparoscopic cholecystectomy. Methods In this double-blind, placebo-controlled, randomized, clinical trial, patients who were candidates for elective LC, from March 2012 to 2015, in four hospitals in Babol, Iran, were studied. Patients were allocated randomly to two groups, i.e., group C: Cefazolin (n = 182) and group P: placebo (n = 247). Group C received 1 g of Cefazolin 30 minutes before anesthesia and and then, six and 12 hours after anesthesia. Group P patients received 10 ml of isotonic sodium chloride solution. Age, gender, type of gallbladder diseases (stone, polyp, or hydrops), the length of post-operative hospitalization, frequency of gallbladder rupture, the duration of surgery, and the kinds of complications associated with infections were collected for each patient in the two groups. The data were analyzed by IBM-SPSS version 20, using the t-test and the chi-squared test, and a p-value < 0.05 was considered as significant. Results There were no significant differences between the two groups in terms of gender (C versus P: 18 (9.9%) male versus 22 (9%); p = 0.74), age (C versus P: 43.75 + 13.30 years versus 40.91 + 13.05; p = 0.20), and duration of surgery (C versus P: 34.97 ± 8.25 min versus 34.11 ± 8.39; p = 0.71). There were no significant differences between the two groups in the incidences of post-operative infection (C versus P: 3 (1.7%) versus 5 (2%); p = 0.99) and rupture of the gallbladder (C versus P: 14 (7.8%) versus 17 (6.8%); p = 0.85). No other post-operative systemic infectious complications (e.g., sepsis, pneumonia, or urinary tract infection) were found

    BACKGROUND: Post-operative nausea and vomiting (PONV) is a ‘big little’ problem especially after laparoscopic surgeries. Palanosetron is a new potent 5 hydroxy tryptamine 3 antagonists. In this randomized double blind clinical study we compared the effects of i.v. ondansetron and palanosetron administered at the end of surgery in preventing post-operative nausea and vomiting in patients undergoing laparoscopic cholecystectomy under general anesthesia. MATERIALS AND METHODS: A total of 100 subjects between 18–60 years with Apfel score ≥2, were randomly assigned into one of the two groups, containing 50 patients each. Group A received ondansetron 4 mg i.v. and Group B received palanosetron 0.07 5mg i.v. both as bolus before induction. The incidence of nausea, retching and vomiting, incidence of total PONV, requirement of rescue antiemetics and adverse effects were evaluated during the first 24 h following end of surgery. RESULTS: The incidence of nausea was significantly lower in patients who had received palanosetron (16%) as compared to ondansetron (24%). Need of rescue antiemetics was significantly higher in patients receiving ondansetron (32%) as compared to palanosetron (16%). The incidence of total PONV was also significantly lower in group receiving palanosetron (20%) as compared to ondansetron (50%). Among the side effects, headache was noted significantly higher with ondansetron (20%) as compared to palanosetron (6%). CONCLUSION: Palanosetron has got better anti-nausea effect, less need of rescue antiemetics, favourable side effect profile and a decrease in the incidence of total PONV as compared to ondansetron in 24 h post operative period in patients undergoing laproscopic cholecystectomy under general anesthesia.

    INTRODUCTION: Both converted and difficult laparoscopic cholecystectomies (LC) have impact on operating time and training of juniors. The aim of this study is to evaluate parameters that predict difficult LC or conversion (C), and find predictive values for different cut-off points of C-reactive protein (CRP) for conversion. MATERIALS AND METHODS: A retrospective cohort study of cholecystectomies performed from January 2011 to December 2012 at NHS trust was undertaken. Association of intra-operative difficulties or conversion with the following factors was studied: Age, gender, CRP, white blood cell count (WBC), history of pancreatitis, and endoscopic retrograde cholangiopancreatography (ERCP). RESULTS: Two hundred and ninety one patients were analysed (222 laparoscopic, 45 difficult LC and 24 C). Only 141 patients had a recorded CRP. Median CRP was highest for patients who were converted (286.20) compared to those who had difficult LC (67.40) or LC (7.05). Those patients who did not have preoperative CRP (8/150, 5.3%) had less chance of conversion than those who had CRP (16/141, 11.34%) (P = 0.063). Patients with CRP of ≤220 (3/91, 3.2%) had significantly less chance of conversion than those with CRP >220 (13/21, 61.9%) (P < 0.001). High preoperative CRP, WBC count and ERCP, were predictors of conversion. These factors were only marginally better than CRP alone in predicting conversion. CONCLUSION: CRP can be a strong predictor of conversion of LC. Further validation of the results is needed. PMID:26917916

    Laparoscopic cholecystectomy has become the standard treatment for gallbladder diseases. However, there are still some patients for whom conversion to open surgery is required. This surgery can produce significant post-operative pain. Opioids drugs have traditionally been used to treat this pain, but side effects have led to seeking alternatives (plexus, nerve or fascia blocks or wound). The cases are presented of 4 patients subjected to ultrasound-guided intercostal branches blocks in the mid-axillary line from T6 to T12 with levobupivacaine as an analgesic alternative in open surgery of gallbladder, with satisfactory results.

    The present study reports a novel approach to laparoscopic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumor (GIST) resection and cholecystectomy, and conducts a review of the associated literature. The novel surgical procedure was performed on one patient who was diagnosed with a GIST and cholecystic polypus. The GIST was resected using an insulation-tipped diathermic electrosurgical knife under the guide of an endoscope. Subsequently, a cholecystectomy was performed by inserting two more 5-mm trocars and instruments transumbilically, guided using an endoscope. The tumor and the gallbladder were exteriorized using a peroral approach and the incision lining of the stomach was sutured laparoscopically. The procedure was successfully performed and the patient experienced no discomfort during the 5-year follow-up. In conclusion, the present study demonstrates that laparoscopic and endoscopic cooperative surgery is feasible and would be an ideal choice for invisible abdominal scar surgery, in particular for multi-visceral resection.

    Background: Postoperative pain is one of the most common complaints after elective laparoscopic cholecystectomy. The present study was aimed to evaluate the effect of paravertebral block using bupivacaine with/without fentanyl on postoperative pain and complications after laparoscopic cholecystectomy. Materials and Methods: This study was done on 90 patients scheduled to undergo elective laparoscopic cholecystectomy. Patients were assessed in two groups: The case group received bupivacaine and fentanyl, and the control group received bupivacaine and normal saline. Primary outcomes were severity of postoperative pain at rest and during coughing. Secondary outcomes were postoperative cumulative morphine consumption and the incidence of side-effects. Results: Pain score at rest before surgery, after recovery, hour-1 and hour-6 was not significantly different between the groups. But in hour-24 cases, the pain score during coughing was significantly higher than controls. Severity of pain at rest in time points was not different between groups. The frequencies (%) of moderate pain at mentioned times in case and control groups were 64, 31, 16, 9, 0 versus 67, 16, 7, 4, and 0, respectively. Pain score during coughing was lower in controls at hour-24 in comparison with cases, but in other time points was not significant. The control group significantly received more total dose of morphine in comparison with cases group. Nausea, vomiting and hypotension were similar in groups, but pruritus was significantly different between the groups. Conclusion: Adding fentanyl to bupivacaine in paravertebral block did not significantly improve the postoperative pain and complications after laparoscopic cholecystectomy. However, further studies are needed to be done. PMID:25250301

    1997-01-01

    Three hundred six injuries or complications coincident to 296 laparoscopic cholecystectomies were analyzed for the nature and extent of injuries and litigious outcomes that followed. The data were drawn from 31 member companies of the Physician Insurers Association of America, a trade association that initiated the study. The outcomes were compared to 261 contemporaneous open cholecystectomy claims. Biliary tract injuries were the most common, accounting for almost two thirds of all injuries. The spectrum of cases, originally selected for indemnity potential, reflected relative incidences in the medical literature. Laparoscopic injuries were significantly more severe, more likely to result in indemnity, and more apt to involve higher mean +/- standard deviation dollar values (160 dollars +/- 154 x 10(3)) to surviving claimants than injuries resulting from open procedures (106 dollars +/- 122 x 10(3), P = 0.01). Injury recognition at the time of the original procedure had no discernible mitigating effect because 80% of recognized injuries required an additional operative procedure. Risk-aversive behavior should include paying particular attention to placement of the first port, more liberal use of the Hasson technique, placement of all other ports under direct vision, elimination of intraoperative anatomic uncertainty, programmed inspection of the abdomen before withdrawing the laparoscope, and acquiring sufficient knowledge of electrosurgical principles to ensure the safe use of this potentially dangerous modality.

    Oscillations in cytosolic-free Ca2+ concentration ([Ca2+]i) have been proposed to encode information that controls stomatal closure. [Ca2+]i oscillations with a period near 10 min were previously shown to be optimal for stomatal closure in Arabidopsis (Arabidopsis thaliana), but the studies offered no insight into their origins or mechanisms of encoding to validate a role in signaling. We have used a proven systems modeling platform to investigate these [Ca2+]i oscillations and analyze their origins in guard cell homeostasis and membrane transport. The model faithfully reproduced differences in stomatal closure as a function of oscillation frequency with an optimum period near 10 min under standard conditions. Analysis showed that this optimum was one of a range of frequencies that accelerated closure, each arising from a balance of transport and the prevailing ion gradients across the plasma membrane and tonoplast. These interactions emerge from the experimentally derived kinetics encoded in the model for each of the relevant transporters, without the need of any additional signaling component. The resulting frequencies are of sufficient duration to permit substantial changes in [Ca2+]i and, with the accompanying oscillations in voltage, drive the K+ and anion efflux for stomatal closure. Thus, the frequency optima arise from emergent interactions of transport across the membrane system of the guard cell. Rather than encoding information for ion flux, these oscillations are a by-product of the transport activities that determine stomatal aperture. PMID:26628748

    IMPORTANCE Abdominal pain after cholecystectomy is common and may be attributed to sphincter of Oddi dysfunction. Management often involves endoscopic retrograde cholangiopancreatography (ERCP) with manometry and sphincterotomy. OBJECTIVE To determine whether endoscopic sphincterotomy reduces pain and whether sphincter manometric pressure is predictive of pain relief. DESIGN, SETTING, AND PATIENTS Multicenter, sham-controlled, randomized trial involving 214 patients with pain after cholecystectomy without significant abnormalities on imaging or laboratory studies, and no prior sphincter treatment or pancreatitis randomly assigned (August 6, 2008-March 23, 2012) to undergo sphincterotomy or sham therapy at 7 referral medical centers. One-year follow-up was blinded. The final follow-up visit was March 21, 2013. INTERVENTIONS After ERCP, patients were randomized 2:1 to sphincterotomy (n = 141) or sham (n = 73) irrespective of manometry findings. Those randomized to sphincterotomy with elevated pancreatic sphincter pressures were randomized again (1:1) to biliary or to both biliary and pancreatic sphincterotomies. Seventy-two were entered into an observational study with conventional ERCP managemeny. MAIN OUTCOMES AND MEASURES Success of treatment was defined as less than 6 days of disability due to pain in the prior 90 days both at months 9 and 12 after randomization, with no narcotic use and no further sphincter intervention. RESULTS Twenty-seven patients (37%; 95%CI, 25.9%-48.1%) in the sham treatment group vs 32 (23%; 95%CI, 15.8%-29.6%) in the sphincterotomy group experienced successful treatment (adjusted risk difference, −15.6%; 95% CI, −28.0% to −3.3%; P = .01). Of the patients with pancreatic sphincter hypertension, 14 (30%; 95% CI, 16.7%-42.9%) who underwent dual sphincterotomy and 10 (20%; 95% CI, 8.7%-30.5%) who underwent biliary sphincterotomy alone experienced successful treatment.

  4. Characterizing emergency departments to improve understanding of emergency care systems

    PubMed Central

    2011-01-01

    International emergency medicine aims to understand different systems of emergency care across the globe. To date, however, international emergency medicine lacks common descriptors that can encompass the wide variety of emergency care systems in different countries. The frequent use of general, system-wide indicators (e.g. the status of emergency medicine as a medical specialty or the presence of emergency medicine training programs) does not account for the diverse methods that contribute to the delivery of emergency care both within and between countries. Such indicators suggest that a uniform approach to the development and structure of emergency care is both feasible and desirable. One solution to this complex problem is to shift the focus of international studies away from system-wide characteristics of emergency care. We propose such an alternative methodology, in which studies would examine emergency department-specific characteristics to inventory the various methods by which emergency care is delivered. Such characteristics include: emergency department location, layout, time period open to patients, and patient type served. There are many more ways to describe emergency departments, but these characteristics are particularly suited to describe with common terms a wide range of sites. When combined, these four characteristics give a concise but detailed picture of how emergency care is delivered at a specific emergency department. This approach embraces the diversity of emergency care as well as the variety of individual emergency departments that deliver it, while still allowing for the aggregation of broad similarities that might help characterize a system of emergency care.

    Energy emergency preparedness is the special responsibility of the Deputy Assistant Secretary of Energy Emergencies within the Office of the Assistant Secretary for International Affairs and Energy Emergencies; though other Department of Energy (DOE) offices manage some aspects and DOE also coordinates emergency management with other federal departments. There are two basic objectives for energy emergency preparedness. The first of these, the economic stabilization objective, seeks to ease the impact of an energy supply disruption by facilitating a quick recovery and minimizing the disruption's economic consequences. The second is the mobilization support objective to ensure that there is adequate energy and fuel to support defense, defense industrial and critical civilian needs for energy and fuel. While all energy systems are vulnerable they vary in the degree of seriousness and the probability of a disruption. Oil is the most vulnerable, and will become increasingly so in the 1990's, as domestic and reliable foreign sources diminish and the United States relies more on imports from volatile Persian Gulf countries. Electric power is the next most vulnerable system, being open particularly to multi-site terrorist attack. This overview examines two highly connected organizations: the Office of Energy Emergencies (OEE) itself and the actual response organization, centering on the Energy Emergency Management System (EEMS). 38 refs., 10 figs.

    We explore the possibility of emergent cosmology using the effective potential formalism. We discover new models of emergent cosmology which satisfy the constraints posed by the cosmic microwave background (CMB). We demonstrate that, within the framework of modified gravity, the emergent scenario can arise in a universe which is spatially open/closed. By contrast, in general relativity (GR) emergent cosmology arises from a spatially closed past-eternal Einstein Static Universe (ESU). In GR the ESU is unstable, which creates fine tuning problems for emergent cosmology. However, modified gravity models including Braneworld models, Loop Quantum Cosmology (LQC) and Asymptotically Free Gravity result in a stable ESU. Consequently, in these models emergent cosmology arises from a larger class of initial conditions including those in which the universe eternally oscillates about the ESU fixed point. We demonstrate that such an oscillating universe is necessarily accompanied by graviton production. For a large region in parameter space graviton production is enhanced through a parametric resonance, casting serious doubts as to whether this emergent scenario can be past-eternal.

    An higher incidence rate of iatrogenic bile duct injuries is reported in cholecystectomy performed with the laparoscopy than with the laparotomy approach. The aim of this study was to provide a multicentre report on surgical treatment and the outcome of biliary complications during and following laparoscopic cholecystectomy. A questionnaire was mailed to all surgeons with experience in laparoscopic cholecystectomy in the Campania region. Data were collected from January 1991 to December 2003. Each patient was requested to indicate age, gender, associated diseases, site and type of lesion, surgical experience, diagnosis, treatment and complications. Twenty-six surgeons answered the questionnaire. Fifty-one patients (36 F/15 M; mean age: 42.5 +/- 11.9, range 13-91 years) with bile duct injuries following laparoscopic cholecystectomy were reported. The most frequent lesions were main bile duct partial or total transection. The intraoperative mortality rate was 1/51 (1.9%) due to a complex biliary and vascular injury. The postoperative mortality rate of revision surgery was 5/50 (10%). T-tube positioning (n = 20) and Roux-en-Y hepato-jejunostomy (n = 20) were the procedures most frequently performed. The complication rate in patients treated with the T-tube was significantly higher than in those treated with hepatico-jejunostomy. Surgical treatment of biliary injuries following laparoscopic cholecystectomy was characterized by unusually high mortality and morbidity for a non-neoplastic disease. Roux-en-Y hepato-jejunostomy remains the procedure of choice for these injuries. PMID:16060179

    Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice for common hepatic duct injury type E2. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of 36-year-old female patient who had undergone elective cholecystectomy 2 mo ago for gall stones and had a common bile duct injury during surgery. As the stricture was old and complete it could not be tackled endoscopically. We did a laparoscopic assisted adhesiolysis followed by robotic Roux-en-Y hepaticojejunostomy. No intraoperative complications or technical problems were encountered. Postoperative period was uneventful and she was discharged on the 4th postoperative day. At follow-up, she is doing well without evidence of jaundice or cholangitis. This is the first reported case of robotic hepaticojejunostomy following common bile duct injury. The hybrid technique gives the patient benefit of laparoscopic adhesiolysis and robotic suturing. PMID:25684934

    OBJECTIVE: The authors determined the most useful predictors of common bile duct (CBD) stones as diagnosed by endoscopic retrograde cholangiopancreatography (ERCP) in patients who underwent laparoscopic cholecystectomy (LC). METHODS: Prospective and retrospective collection of historical, biochemical and ultrasonographic data was used. Receiver operating characteristics curve analysis was used to determine optimal biochemical cut-off values. Multivariate analysis using logistic regression with generation of the best model identifying independent predictors of CBD stones also was employed. Prospective validation of the model was performed on an independent group of patients. RESULTS: Endoscopic retrograde cholangiopancreatographies were performed before LC in 106 patients, and after LC in 33. Only four of ten clinical variables evaluated independently predicted the presence of CBD stones. The optimal model predicted a 94% probability of CBD stones in a patient older than 55 years of age who presented with an elevated bilirubin (over 30 mumol/L) and positive ultrasound findings (a dilated CBD, and a CBD stone seen on ultrasound). This model was validated prospectively in a subsequent series of 49 patients in which the probability of CBD stone was only 8% when all four predictors were absent. CONCLUSIONS: The identified independent clinical predictors of a CBD stone helps select a population of symptomatic gallstone bearers who benefit most from cholangiographic assessment. PMID:7517657

    Alongside the technique based on the creation of an abdominal cavity for surgery following the introduction of gas (usually CO2) into the peritoneal cavity, a new method has been developed. This involves the use of an atraumatic mechanical lifting device connected to the same abdominal wall (gasless laparoscopy). The authors report a technique that uses an inflatable cushion inserted into the abdomen through a periumbilical incision. The cushion is connected to an external motorized hydraulic jack fixed to the operating table, fitted with an electric motor and friction gear. Between May 1991 and June 1998, 580 patients underwent laparoscopic cholecystectomy. Since December 1995 a total of 130 patients have undergone surgery using gasless laparoscopy. Shoulder pain and pain in the upper abdominal quadrant were no longer reported; pain was present in 70% of the patients operated using the CO2 technique. There was also a marked reduction in the anesthesiological risks, above all in elderly patients with cardiopulmonary insufficiency. Surgical manoeuvres are made easier owing to the possibility of using traditional surgical instruments. Washing and continuous aspiration allow a good control of intraoperative hemostasis, and reduce the phenomenon of lens misting without the risk of losing pneumoperitoneum. Less visibility of the surgical field was reported, particularly in obese patients, above all because of the reduced diaphragmatic distension and the lack of displacement of the intestinal loops. In the authors' opinion the gasless technique is suitable above all in patients affected by cardiopulmonary disorders in whom hypercapnia might represent a significant operating risk. PMID:10859952

    The concept of contextual emergence has been proposed as a nonreductive, yet well-defined relation between different levels of description of physical and other systems. It yields a formally sound and empirically applicable procedure to translate between descriptive levels in an overall consistent fashion. This will be discussed for the contextual emergence of mental states from a neural level of description.

    Background: Anesthesia and surgery-induced neuroendocrine stress response can be modulated by appropriate premedication. The present study was designed to assess the clinical efficacy of dexmedetomidine versus fentanyl premedication for modulation of neuroendocrine stress response by analyzing the perioperative variation of blood glucose level during laparoscopic cholecystectomy under general anesthesia. Subjects and Methods: In a prospective randomized double-blind study, 60 adult consented patients of either sex with ASA I and II, scheduled for elective laparoscopic cholecystectomy under general anesthesia and meeting the inclusion criteria, were allocated into two groups. Group D patients (n = 30) were given intravenous dexmedetomidine 1μg/kg and Group F patients (n = 30) received fentanyl 2 μg/kg, given over a 10-min period, before induction of anesthesia. Perioperative blood glucose levels were analyzed preoperatively, at 30 min after beginning of surgery, and 2.5 h after surgery. Anesthetic and surgical techniques were standardized. All patients were also assessed for intraoperative hemodynamic changes of heart rate and mean arterial pressure at specific timings. Results: Blood glucose concentration has shown 20% increase after surgery. The differences between groups were not statistically significant as observed by analyzing the variation of serial perioperative blood glucose estimation. Both premedicants had attenuated the hemodynamic and neuroendocrine stress response of pneumoperitoneum and general anesthesia. The dexmedetomidine group showed more stabilization of intraoperative hemodynamics of mean arterial blood pressure and heart rate when compared to fentanyl group. Conclusion: During the laparoscopic cholecystectomy, dexmedetomidine and fentanyl, both premedicants have effectively modulated the neuroendocrine stress response of general anesthesia as assessed by analysis of perioperative blood glucose variation, but dexmedetomidine was better.

    Background Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. Aim To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Methods Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. Results From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Conclusions Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the

    To determine the causes underlying the formation of adult choledochal cyst.Anomalous pancreaticobiliary junction is the most widely accepted theory regarding the etiology of choledochal cyst. However, choledochal cysts have been found in patients in the absence of this anomaly. Because the number of adult patients with choledochal cyst is increasing, it is important to address this controversy.Bile amylase levels in the cysts of 27 patients (8 males and 19 females) who had undergone cholecystectomy were retrospectively evaluated.The average age of the 27 patients was 45.8 ± 10.1 years and the majority (85.2%) were diagnosed with Todani type I cysts. None of the patients had dilatation of the common bile duct prior to surgery. There were 6 (22.2%) patients with anomalous pancreaticobiliary junction. However, amylase levels did not significantly differ between patients with and without this anomaly (P = 0.251). According to bile amylase levels, pancreatobiliary reflux was present in 21 (77.8%) patients. The mean amylase level significantly differed in patients with pancreatobiliary reflux (23,462 ± 11,510 IU/L) and those without (235 ± 103 IU/L) (P < 0.001). In patients with pancreatobiliary reflux, only 4 patients had anomalous pancreaticobiliary junction. That is, the majority of patients (17/21, 81%) having pancreatobiliary reflux did not have an anomalous junction of the pancreatic and biliary ducts.Since the only explanation for pancreatobiliary reflux in patients with a normal pancreaticobiliary junction is sphincter of Oddi dysfunction, we proposed that the formation of adult choledochal cyst is mainly due to sphincter of Oddi dysfunction.

    Background Cholelithiasis is prevalent surgical disease, with approximately 60,000 admissions per year in the Unified Health System in Brazil. Is often asymptomatic or oligosymptomatic and major complications arise from the migration of calculi to low biliary tract. Despite these complications are severe and life threatening, some patients refuse surgical treatment. Aim To understand why individuals with cholelithiasis refuse cholecystectomy before complications inherent to the presence of gallstones in the bile duct and pancreatitis occur. Methods To investigate the universe of the justifications for refusing to submit to surgery it was performed individual interviews according to a predetermined script. In these interviews, was evaluate the knowledge of individuals about cholelithiasis and its complications and the reasons for the refusal of surgical treatment. Were interviewed 20 individuals with cholelithiasis who refused or postponed surgical treatment without a plausible reason. To these interviews, was applied the technique of thematic analysis (Minayo, 2006). Results The majority of respondents had good knowledge of their disease and its possible complications, were well oriented and had surgical indications by their physicians. The refusal for surgery was justified primarily on negative experiences of themselves or family members with surgery, including anesthesia; fear of pain or losing their autonomy during surgery and postoperative period, preferring to take the risk and wait for complications to then solve them compulsorily. Conclusion The reasons for the refusal to surgical resolution of cholelithiasis were diverse, but closely related to personal (or related persons) negative surgical experiences or complex psychological problems that must be adequately addressed by the surgeon and other qualified professionals.

    Introduction and Aim: Use of transversus abdominis plane block (TAP) in the management of postoperative pain after the laparoscopic cholecystectomy (LC) has been a common anesthetic practice. This study evaluates the effect of adding magnesium sulfate to bupivacaine in TAP block in LC regarding postoperative analgesia and analgesic consumption. Patients and Methods: Ninety patients of American Society of Anesthesiologists I and II was divided into three groups: Control group (C group, n = 30), bupivacaine group (B group, n = 30), bupivacaine magnesium group (M group, n = 30). Results: M group showed better analgesic profile in the 1st postoperative day in the form of lower mean visual analog scale score (2.8 ± 0.6 for C group, 2.1 ± 0.5 for B group, 2.2 ± 0.5 for M group, P < 0.001), longer duration of analgesia (7 ± 2.8 h for C group, 16 ± 2.5 h for B group, 19 ± 2.2 h for M group, P < 0.006), lower morphine consumption (2 ± 0.1 mg for C group, 0.9 ± 0.1 mg for B group, 0.5 ± 0.1 mg for M group, P < 0.011). There was a significant lower incidence of postoperative nausea and vomiting (PONV) (32% for C group, 6% B group, 7% M group, P < 0.004). Conclusion: Adding MgSo4 as an adjuvant to bupivacaine in TAP block; during anesthesia for LC; improved postoperative analgesia in the form of increased duration, decreased analgesic requirements and PONV.

    Rheumatological conditions can sometimes present as emergencies. These can occur due to the disease process or infection; contrary to what many people think, rheumatologic emergencies like a pain, rheumatic crisis, or attack gout do not compromise the patient's life. This article mentioned only true emergencies: catastrophic antiphospholipid syndrome (cAPS), kidney-lung syndrome, central nervous system (CNS) vasculitis, anti-Ro syndrome (neonatal lupus), and macrophage activation syndrome (MAS). The management of above emergencies includes critical care, immunosuppression when indicated, and use of a diagnostic flowchart as well as fast laboratory profile for making decisions. Anticoagulants have to be used in the management of antiphospholipid syndrome. A good understanding of these conditions is of paramount importance for proper management. PMID:26099604

    Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up. PMID:27468181

    Emergency contraception is used to prevent pregnancy after a coital act not adequately protected by a regular method of contraception. In contrast to early medical abortion, emergency contraception prevents a pregnancy from starting and does not disrupt an established pregnancy. The most commonly used approaches consist of two oral doses of contraceptive steroids. The levonorgestrel-only regimen (levonorgestrel, 0.75 mg, repeated in 12 hours) appears to be more effective and better tolerated than the Yuzpe regimen (ethinyl estradiol, 100 microg, and levonorgestrel, 0.5 mg, repeated in 12 hours). In the largest randomized, controlled trial to date, levonorgestrel prevented about 85% of pregnancies that would have occurred without its use. Hormonal emergency contraception has no known medical contraindications, although it is not indicated for suspected or confirmed pregnancy. However, if hormonal emergency contraception is inadvertently taken in early pregnancy, neither the woman nor the fetus will be harmed. Nausea and vomiting associated with the Yuzpe regimen can be reduced by prophylactic use of meclizine. A strong medical and legal case exists for making hormonal emergency contraception available over the counter, as has happened in countries other than the United States. Easier access to and wider use of emergency contraception could dramatically lower the high rates of unintended pregnancy and induced abortion in the United States. PMID:12160366

    Background. Laparoscopic cholecystectomy is usually carried out under general anesthesia. There were a few studies which have found spinal anesthesia as a safe alternative. We aimed to evaluate the postoperative events between spinal anesthesia and general anesthesia in patients undergoing laparoscopic cholecystectomy. Methods. We searched PubMed, Embase, and Cochrane Library (from inception to January 2016) for eligible studies. The primary outcome was the visual analogue scale score. Secondary outcomes included postoperative nausea and vomiting and urine retention 24 hours postoperatively. We calculated pooled risk ratios and 95% confidence interval using random- or fixed-effects models. Results. Eight trials involving 723 patients were listed. Meta-analysis showed that patients in spinal anesthesia groups have lower visual analogue scale score 24 hours postoperatively. There were significant decreases in the occurrence of postoperative nausea and vomiting in spinal anesthesia group when compared with general anesthesia group (odds ratios: 0.38, 95% confidence interval: 0.19-0.76; P = 0.006) with heterogeneity accepted (I (2) = 13%; P = 0.33), while urine retention rate was increased in patients with spinal anesthesia (odds ratios: 4.95, 95% confidence interval: 1.24-19.71; P = 0.02) without any heterogeneity (I (2) = 0%; P = 0.98). Conclusions. Spinal anesthesia may be associated with less postoperative pain and postoperative nausea and vomiting compared with general anesthesia. PMID:27525282

    During laparoscopic cholecystectomy, intraoperative cholangiography (IOC) is used to identify common bile duct (CBD) stones. In patients whose IOC is suspicious for stones, endoscopic retrograde cholangiopancreatography (ERCP) is the modality of choice for stone removal. However, IOC has a false positive rate of 30 to 60 per cent, and ERCP adverse events may occur in 11 per cent of patients. Endoscopic ultrasound (EUS) may serve as a noninvasive means of diagnosing suspected CBD stones. This study sought to assess the role of EUS in predicting the likelihood of choledocholithiasis at ERCP in patients found to have a positive IOC. This was a prospective blinded study of EUS before ERCP in patients with a positive IOC. Recruited subjects who underwent cholecystectomy and had an IOC with suspicion for obstruction were referred for ERCP within one month of their procedure. In patients with a positive IOC, EUS had a positive predictive value of 95 per cent in detecting choledocholithiasis. IOC with single or multiple filling defects more often correlated to the presence of CBD stones. At ERCP, choledocholithiasis was present in 65 per cent of patients who had an IOC suspicious for CBD stones. EUS should be used as a noninvasive method to correctly identify retained CBD stones in low-to-moderate risk patients with a positive IOC. PMID:27097628

    Background Laparoscopic cholecystectomy (LC) can be technically challenging in the obese. The primary aim of the trial was to establish whether following a Very Low Calorie Diet (VLCD) for two weeks pre-operatively reduces operation time. Secondary outcomes included perceived operative difficulty and length of hospital stay. Methods A single-blinded, randomized controlled trial of consecutive patients with symptomatic gallstones and BMI >30 kg/m2 46 patients were randomized to a VLCD or normal diet for two weeks prior to LC. Food diaries were used to document dietary intake. The primary outcome measure was operation time. Secondary outcomes were length of stay, weight change operative complications, day case rates and perceived difficulty of operation. Results The VLCD was well tolerated and had significantly greater preoperative weight loss (3.48 kg vs. 0.98 kg; p < 0.0001). Median operative time was significantly reduced by 6 min in the VLCD group (25 vs. 31 min; p = 0.0096). There were no differences in post-operative complications, length of stay, or day case rates between the groups. Dissection of Calot's triangle was deemed significantly easier in the VLCD group. Conclusion A two week VLCD prior to elective laparoscopic cholecystectomy in obese patients is safe, well tolerated and was shown to significantly reduce pre-operative weight and operative time.

This study aimed to compare the efficacy of ultrasound guided abdominal field blocks (USAFB) with port site infiltrations for post-operative analgesia in terms of quality of pain relief, opioid consumption and patient satisfaction for day care surgeries Methods: Eighty patients presenting for laparoscopic cholecystectomy were randomly allocated to two groups either to receive port-site infiltration of local anaesthetic (n = 40, Group A) or USAFB (n = 40, Group B group). Numeric rating scores (NRS) were measured postoperatively to primarily assess the pain severity and opioid requirements. Data were analysed using Chi-Square test/Fisher's exact test for categorical data and Mann–Whitney test/unpaired t-test for quantitative data. Results: The study group (Group B) had significantly reduced NRS and opioid consumption over 24 h. The overall fentanyl consumption in patients receiving port infiltrations was approximately twice (200 ΁ 100 μg) as compared to patients in USAFB group (120 ΁ 74 μg) (P < 0.0001). Maximum fentanyl consumption was 400 μg (Group A) and 262 μg (Group B) over 24 h and the minimum requirement was 50 μg and zero, respectively. Conclusion: Superior post-operative analgesia was observed with USAFB which may help in minimising opioid-related adverse effects and facilitating faster recovery.

    The Bunyavidae family is the largest grouping of RNA viruses and arguably the most diverse. Bunyaviruses have a truly global distribution and can infect vertebrates, invertebrates and plants. The majority of bunyaviruses are vectored by arthropods and thus have the remarkable capability to replicate in hosts of disparate phylogeny. The family has provided many examples of emerging viruses including Sin Nombre and related viruses responsible for hantavirus cardiopulmonary syndrome in the Americas, first identified in 1993, and Schmallenberg virus which emerged in Europe in 2011, causing foetal malformations in ruminants. In addition, some well-known bunyaviruses like Rift Valley fever and Crimean-Congo haemorrhagic fever viruses continue to emerge in new geographical locations. In this short review we focus on newly identified viruses associated with severe haemorrhagic disease in humans in China and the US. PMID:24607799

    High rates of adolescent pregnancy remain a challenge for health care providers. For most sexually active adolescents, pregnancy is unintended. Emergency contraception, also called the "morning-after-pill" or postcoital contraception, is a way to prevent pregnancy after unprotected intercourse. In the United States, three forms of emergency contraception currently are available: high-dose combination estrogen and progestin pills, high-dose progestin-only pills, and postcoital insertion of a copper intrauterine device. The postcoital intrauterine device is used infrequently. When emergency contraceptive pills (ECPs) are taken within 72 hours of unprotected intercourse, they reduce the risk of pregnancy by at least 75%. However, they are most effective if taken within 24 hours of coitus. Eleven brands of pills currently are marketed in the United States that conform to the regimens approved by the Food and Drug Administration (FDA) for this indication. Recently, two prepackaged ECPs were approved by the FDA. The only medical contraindication to prescribing ECPs is pregnancy. The most common side effects are nausea and vomiting, followed by menstrual disturbances, breast tenderness, abdominal cramping, dizziness, headache, and mood changes. Because vomiting can compromise the efficacy of ECPs, routine pretreatment with an antiemetic is recommended. Primary care providers can reduce unintended adolescent pregnancy by routinely counseling adolescents at all office visits about the existence of emergency contraception and by prescribing it in advance and over the telephone.

    Background: Laparoscopy though minimally invasive produces significant hemodynamic surge and neuroendocrine stress response. Though general anesthesia (GA) is the conventional technique, now-a-days, regional anesthesia has been accepted for laparoscopic diagnostic procedures, and its use is also being extended to laparoscopic surgeries. Objective: The aim was to compare the hemodynamic surge and neuroendocrine stress response during laparoscopic cholecystectomy (LC) under GA and spinal anesthesia (SA) in American Society of Anesthesiologists (ASA) PS 1 patients. Materials and Methods: Thirty ASA physical status I patients, aged 18-65 years were randomly allocated into two equal groups of 15 each. Group A received GA with controlled ventilation. Patients were preoxygenated for 5 min with 100/5 oxygen, premedicated with midazolam 0.03 mg/kg intravenous (i.v), fentanyl 2 mcg/kg i.v; induction was done with thiopentone 3-5 mg/kg i.v; intubation was achieved after muscle relaxation with 0.5 mg/kg atracurium besylate i.v. Anesthesia was maintained with 1-2% sevoflurane and N2O:O2 (60:40) and intermittent i.v injection of atracurium besylate. Group B SA with 0.5% hyperbaric bupivacaine and 25 μg fentanyl along with local anesthetic instillation in the subdiaphragmatic space. Mean arterial pressure, heart rate (HR), oxygen saturation, end tidal carbon-dioxide were recorded. Venous blood was collected for cortisol assay before induction and 30 min after pneumoperitoneum. All data were collected in Microsoft excel sheet and statistically analyzed using SPSS software version 16 (SPSS Inc., Chicago, IL, USA). All numerical data were analyzed using Student's t-test and paired t-test. Any value <0.05 was taken as significant. Results: Mean arterial pressure and mean HR and postpneumoperitoneum cortisol level were lower in group B than group A though the difference was not statistically significant in hemodynamic parameters but significant in case of cortisol. Conclusion: Spinal

    Pressure-controlled ventilation (PCV) is less frequently employed in general anesthesia. With its high and decelerating inspiratory flow, PCV has faster tidal volume delivery and different gas distribution. The same tidal volume setting, delivered by PCV versus volume-controlled ventilation (VCV), will result in a lower peak airway pressure and reduced risk of barotrauma. We hypothesized that PCV instead of VCV during laparoscopic surgery could achieve lower airway pressures and reduce the systemic stress response. Forty ASA I-II patients were randomly selected to receive either the PCV (Group PC, n = 20) or VCV (Group VC, n = 20) during laparoscopic cholecystectomy. Blood sampling was made for baseline arterial blood gases (ABG), cortisol, insulin, and glucose levels. General anesthesia with sevoflurane and fentanyl was employed to all patients. After anesthesia induction and endotracheal intubation, patients in Group PC were given pressure support to form 8 mL/kg tidal volume and patients in Group VC was maintained at 8 mL/kg tidal volume calculated using predicted body weight. All patients were maintained with 5 cmH2O positive-end expiratory pressure (PEEP). Respiratory parameters were recorded before and 30 min after pneumoperitonium. Assessment of ABG and sampling for cortisol, insulin and glucose levels were repeated 30 min after pneumoperitonium and 60 min after extubation. The P-peak levels observed before (18.9 ± 3.8 versus 15 ± 2.2 cmH2O) and during (23.3 ± 3.8 versus 20.1 ± 2.9 cmH2O) pneumoperitoneum in Group VC were significantly higher. Postoperative partial arterial oxygen pressure (PaO2) values are higher (98 ± 12 versus 86 ± 11 mmHg) in Group PC. Arterial carbon dioxide pressure (PaCO2) values (41.8 ± 5.4 versus 36.7 ± 3.5 mmHg) during pneumoperitonium and post-operative mean cortisol and insulin levels were higher in Group VC. When compared to VCV mode, PCV mode may improve compliance during pneumoperitoneum

    The use of intravenous dexmedetomidine during surgery has been shown to suppress inflammatory cytokines peri-operatively. It has also been demonstrated that dexmedetomidine may benefit cognitive function in elderly patients following surgery; however, it is not clear whether dexmedetomidine reduces postoperative cognitive dysfunction (POCD) via the suppression of inflammatory cytokines. The aim of the present study was to investigate the effects of dexmedetomidine on early POCD and inflammatory cytokines in elderly patients undergoing laparoscopic cholecystectomy (LC). The study comprised 120 elderly patients undergoing selective LC, who were randomly allocated to receive either dexmedetomidine intravenously (DEX group, n=60) or the same volume of normal saline (control group, n=60). Cognitive function was assessed by Mini-Mental State Examination (MMSE) scores 1 day prior to surgery, 6 h following surgery and postoperatively on days 1 and 2. Interleukin (IL)-1β, IL-6 and C-reactive protein (CRP) levels were also measured at these time-points. On the basis of whether the patients had POCD on the first day after surgery, patients were divided into a POCD group and a non-POCD group. Blood cytokine levels were compared between the patients with and without POCD. A total of 100 patients completed both pre- and postoperative MMSE tests. At 1 day following surgery, POCD occurred in 10/50 (20%) patients in the DEX group and in 21/50 (42%) patients in the control group (P=0.017). At 6 h following surgery, IL-1β, IL-6 and CRP levels showed significant increases (P<0.01) compared with the baseline levels in the two groups. Furthermore, in the control group, CRP levels showed a significant increase on day 1 (P<0.001) and day 2 (P=0.017) postoperatively. In the DEX group compared with the control group, IL-1β, IL-6 and CRP levels were markedly decreased at 6 h and 1 day after surgery (P<0.01). Concentrations of IL-1β, IL-6 and CRP were significantly higher in patients who

    Emergency post-coital contraception (EC) is an effective method of preventing pregnancy when used appropriately. EC has been available since the 1970s, and its availability and use have become widespread. Options for EC are broad and include the copper intrauterine device (IUD) and emergency contraceptive pills such as levonorgestrel, ulipristal acetate, combined oral contraceptive pills (Yuzpe method), and less commonly, mifepristone. Some options are available over-the-counter, while others require provider prescription or placement. There are no absolute contraindications to the use of emergency contraceptive pills, with the exception of ulipristal acetate and mifepristone. This article reviews the mechanisms of action, efficacy, safety, side effects, clinical considerations, and patient preferences with respect to EC usage. The decision of which regimen to use is influenced by local availability, cost, and patient preference. PMID:24453516

    In this work, we propose a novel search strategy for new physics at the LHC that utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have many different vertices within the jet cone. Such emerging jet signatures are smoking guns for models with a composite dark sector where a parton shower in the dark sector is followed by displaced decays of dark pions back to SM jets. No current LHC searches are sensitive to this type of phenomenology. We perform a detailed simulation for a benchmark signal with two regular and two emerging jets, and present and implement strategies to suppress QCD backgrounds by up to six orders of magnitude. At the 14 TeV LHC, this signature can be probed with mediator masses as large as 1.5 TeV for a range of dark pion lifetimes, and the reach is increased further at the high-luminosity LHC. The emerging jet search is also sensitive to a broad class of long-lived phenomena, and we show this for a supersymmetric model with R-parity violation. Possibilities for discovery at LHCb are also discussed.

    Hypertensive emergencies are uncommon and physiologically diverse. Consequently, it is difficult for most physicians to develop a familiarity with all the different hypertensive crises and with all drugs available for treating them (Table 4). Clinicians should not agonize over which is the perfect therapeutic agent for a particular emergency, but instead, they should focus on scrupulous monitoring and familiarize themselves with a few agents that will serve in most situations. Generally, these agents will be sodium nitroprusside and nitroglycerin. Vigilant neurologic monitoring is mandatory in all hypertensive emergencies. The early symptoms and signs of cerebral hypoperfusion can be vague and subtle, but if recognized, serious complications of therapy can be avoided. Remember, the patient may still be hypertensive. Avoid acute (during the first hour) reductions in MAP of more than 20% whenever possible; subsequent reductions should be gradual. In patients known to have markedly elevated ICP and who need acute reductions in their BP, serious consideration should be given to direct monitoring of the ICP so that CPP can be maintained within safe limits. In general, oral agents should not be used for the treatment of hypertensive emergencies. Intravenous Labetalol and intravenous nicardipine are not suitable for general use in hypertensive emergencies. In special situations (e.g., perioperative hypertension and subarachnoid hemorrhage), however, they may be employed. Their role may expand with further study. Trimethaphan may be superior to nitroprusside for hypertension complicated by elevated ICP or cerebral dysfunction. Realistically, most physicians will continue to use nitroprusside. Intense neurologic monitoring is more important than the specific agent used. Nitroglycerin is the agent of choice for acute ischemic heart disease complicated by severe hypertension; if it fails, use nitroprusside. For aortic dissection, the combination of nitroprusside and IV

    Psychiatric emergencies are acute disturbances in thought, behavior, mood, or social relationship that require immediate intervention as defined by the patient, family, or social unit to save the patient and/or others from imminent danger. Ensuring the safety of the patient, surrounding persons, and the medical team is the first step of evaluation. Treatment focuses on stabilization of the patient, then on specific symptoms and ultimately the cause of symptoms. There are important legal considerations, particularly regarding involuntary admissions. It is important to debrief with the patient, surrounding family, and the health care team to ensure a continued therapeutic alliance and the emotional health of all involved. PMID:27262012

    Background and Aim: Dexmedetomidine is a α2 agonist with sedative, sympatholytic and analgesic properties and hence, it can be a very useful adjuvant in anaesthesia as stress response buster, sedative and analgesic. We aimed primarily to evaluate the effects of low dose dexmedetomidine infusion on haemodynamic response to critical incidences such as laryngoscopy, endotracheal intubation, creation of pneumoperitoneum and extubation in patients undergoing laparoscopic cholecystectomy. The secondary aims were to observe the effects on extubation time, sedation levels, post-operative analgesia requirements and occurrence of adverse effects. Methods: Sixty patients of American Society of Anaesthesiologists(ASA) physical grades I and II undergoing laparoscopic cholecystectomy were randomly allocated into three groups of 20 patients each. Group NS patients received normal saline, Group Dex 0.2 and Group Dex 0.4 patients received dexmedetomidine infusion at 0.2 mcg/kg/h and 0.4 mcg/kg/h respectively, starting 15 min before induction and continued till end of surgery. Parameters noted were pulse rate, mean arterial pressure, oxygen saturation, post-operative sedation and analgesia requirements. SPSS 15.0 version software was used for statistical analysis. ANOVA test for continuous variables, post-hoc test for intergroup comparison, and Chi-square test for discrete values were applied. Results: In Group NS significant haemodynamic stress response was seen following laryngoscopy, tracheal intubation, creation of pneumoperitoneum and extubation. In dexmedetomidine groups, the haemodynamic response was significantly attenuated. The results, however, were statistically better in Dex 0.4 group compared with Dex 0.2 group. Post-operative 24 hour analgesic requirements were much less in dexmedetomidine groups. No significant side effects were noted. Conclusion: Low dose dexmedetomidine infusion in the dose of 0.4 mcg/kg/h effectively attenuates haemodynamic stress response during

    Morgagni-Larrey hernia (MH) is an unusual diaphragmatic hernia of the retrosternal region. Few cases of MH, treated laparoscopically, associated with Down's syndrome (DS) have been reported in literature. On October 2004, a DS 40-year-old male was admitted to our Department with mild abdominal pain and nausea. Hematochemical tests were within the normal range. Ultrasonography showed biliary sludge and multiple gallstones. Chest X-ray revealed a right-sided paracardiac mass that appeared as MH after a thoraco-abdominal computed tomography (CT). Four trocars were placed as a routinary cholecystectomy. Abdominal exploration confirmed the presence of a voluminous hernia through a wide diaphragmatic defect (12 cm) on the left side of the falciform ligament, containing the last 20 cm ileal loops and right colon with the third lateral of transverse. After retrograde cholecystectomy and reduction of the herniated ileo-colonic tract from multiple adherences, the defect was repaired with an interrupted 2/0 silk suture and then a running 2/0 polypropylene suture. Postoperative course was complicated by pulmonary edema but subsequently the patient was discharged without further complications and has no recurrence after 2 years. In conclusion, surgery is necessary for symptomatic MH and to prevent possible severe complications. We preferred laparoscopy for the reduced morbidity compared to laparotomy, even if in our case the postoperative course was not uneventful. There are still few comparative data about the modality of closure of the defect between primary repair with nonabsorbable suture material, in case of small defects, or continuous monofilament suture or prosthesis in case of large defects.

    Background and Aims: Transversus abdominis plane (TAP) block is a popular technique for post-operative analgesia in abdominal surgeries. The aim of the study was to evaluate the relative efficacy of bupivacaine versus ropivacaine for post-operative analgesia using ultrasound-guided TAP block in laparoscopic cholecystectomies. Methods: Sixty adults undergoing elective laparoscopic cholecystectomy were randomised to receive ultrasound-guided TAP block at the end of the surgical procedure with either 0.25% bupivacaine (Group I, n = 30) or 0.375% ropivacaine (Group II, n = 30). All patients were assessed for post-operative pain and rescue analgesic consumption at 10 min, 30 min, 1 h, 4 h, 8 h, 12 h and 24 h time points. Means for normally distributed data were compared using Student's t-test, and proportions were compared using Chi-square or Fisher's exact test whichever was applicable. Results: Patients receiving ultrasound-guided TAP block with ropivacaine (Group II) had significantly lower pain scores when compared to patients who received the block with bupivacaine (Group I) at 10 min, 30 min and 1 h. However, both the drugs were equivalent for post-operative analgesia and 24 h cumulative rescue analgesic requirement (median [interquartile range]) (75.00 [75.00–75.00] in Group I vs. 75.00 [75.00–93.75] in Group II, P = 0.366). Conclusion: Ultrasound-guided TAP block with ropivacaine provides effective analgesia in the immediate post-operative period up to 1 h as compared to bupivacaine. However, both the drugs are similar in terms of 24 h cumulative rescue analgesic requirement. PMID:27141110

    Abstract Background: Robotic cholecystectomy (RC) using port sites in the lower abdominal area (T12-L1) rather than the upper abdomen has recently been introduced as an alternative procedure for laparoscopic cholecystectomy. Therefore, we investigated the time course of different components of pain and the analgesic effect of the bilateral ultrasound-guided split injection technique for rectus sheath block (sRSB) after RC in female patients. Methods: We randomly assigned 40 patients to undergo ultrasound-guided sRSB (RSB group, n = 20) or to not undergo any block (control group, n = 20). Pain was subdivided into 3 components: superficial wound pain, deep abdominal pain, and referred shoulder pain, which were evaluated with a numeric rating scale (from 0 to 10) at baseline (time of awakening) and at 1, 6, 9, and 24 hours postoperatively. Consumption of fentanyl and general satisfaction were also evaluated 1 hour (before discharge from the postanesthesia care unit) and 24 hours postoperatively (end of study). Results: Superficial wound pain was predominant only at awakening, and after postoperative 1 hour in the control group. Bilateral ultrasound-guided sRSB significantly decreased superficial pain after RC (P < 0.01) and resulted in a better satisfaction score (P < 0.05) 1 hour after RC in the RSB group compared with the control group. The cumulative postoperative consumption of fentanyl at 6, 9, and 24 hours was not significantly different between groups. Conclusions: After RC with lower abdominal ports, superficial wound pain predominates over deep intra-abdominal pain and shoulder pain only at the time of awakening. Afterwards, superficial and deep pain decreased to insignificant levels in 6 hours. Bilateral ultrasound-guided sRSB was effective only during the first hour. This limited benefit should be balanced against the time and risks entailed in performing RSB. PMID:27495072

    Background and Aims: Postoperative pain for day surgery laparoscopic cholecystectomy has traditionally been managed with the surgeon infiltrating the wound with local anesthetic (LA). However, transversus abdominis plane (TAP) block has recently been used, although its superiority over LA remains uncertain. The primary aim was to compare LA and TAP block pain scores and analgesia used. The secondary aim was to assess satisfaction score and cost. Material and Methods: This retrospective study was commenced after ethics committee approval and ANZ clinical trial registry (ACTRN: 12612000737831). The data were collected from the theatre database and medical records of patients presenting for day case laparoscopic cholecystectomy. The sample included patients who received either bilateral port site LA infiltration with 20 ml of 0.25% Bupivacaine or bilateral TAP block with 20 ml of 0.5% ropivacaine and fentanyl postoperative pain protocol. The patients with incomplete medical records were excluded as were those admitted to an inpatient ward. Demographics and clinical characteristics were obtained from the hospital record along with pain score and postsurgery analgesia use. Postoperative pain satisfaction scores were collected by telephonic interview 30-180 days postsurgery. Results: Of 51 patients analyzed, 19 were in TAP group 29 in LA group. There were no significant differences between the LA and TAP groups with respect to postoperative pain scores (P = 0.31) or patient satisfaction scores (1 and 2+) (P = 0.36). However, fentanyl consumption in the recovery room was significantly lower in TAP group (P = 0.0079.). The consumables cost were >3 times higher in the TAP when compared to LA group. Conclusion: The performance of the TAP block with respect to pain management was comparable to LA. However, LA remains more cost effective. PMID:27006547

    A lighting system originally developed for NASA's Apollo and Skylab manned spacecraft resulted in a industrial spinoff and creation of a whole new company to produce and market the product line. The company is UDEC Corp., Waltham, Mass. UDEC's "Multi-Mode" electronic lighting systems are designed for plant emergency and supplemental use, such as night lighting, "always-on" stairwell lights and illuminated exit signs. Their advantages stem from the qualities demanded for spacecraft installation: extremely high fight output with very low energy drain, compactness, light weight, and high reliability. The Multi-Mode system includes long-life fluorescent lamps operated by electronic circuitry, a sealed battery that needs no maintenance for 10 years, and a solid-state battery charger. A typical emergency installation consists of a master module with battery and an eight watt lamp, together with four remote "Satellight" modules powered by the master's battery. As a night lighting system for maintenance or I security, UDEC fixtures can bypass the battery and 1 operate on normal current at a fraction of the energy 1 demand of conventional night lighting. Industrial customers have realized savings of better than ninety percent with UDEC night lights. UDEC started as a basement industry in 1972 but the company has already sold more than 1,000 lighting systems to building operators.

    1983-01-01

    A liquid metal cooled fast breeder reactor provided with an emergency core cooling system includes a reactor vessel which contains a reactor core comprising an array of fuel assemblies and a plurality of blanket assemblies. The reactor core is immersed in a pool of liquid metal coolant. The reactor also includes a primary coolant system comprising a pump and conduits for circulating liquid metal coolant to the reactor core and through the fuel and blanket assemblies of the core. A converging-diverging venturi nozzle with an intermediate throat section is provided in between the assemblies and the pump. The intermediate throat section of the nozzle is provided with at least one opening which is in fluid communication with the pool of liquid sodium. In normal operation, coolant flows from the pump through the nozzle to the assemblies with very little fluid flowing through the opening in the throat. However, when the pump is not running, residual heat in the core causes fluid from the pool to flow through the opening in the throat of the nozzle and outwardly through the nozzle to the assemblies, thus providing a means of removing decay heat.

    Quantum mechanics and relativity in the continuum imply the well known spin–statistics connection. However for particles hopping on a lattice, there is no such constraint. If a lattice model yields a relativistic field theory in a continuum limit, this constraint must “emerge” for physical excitations. We discuss a few models where a spin-less fermion hopping on a lattice gives excitations which satisfy the continuum Dirac equation. This includes such well known systems such as graphene and staggered fermions. -- Highlights: •The spin–statistics theorem is not required for particles on a lattice. •Spin emerges dynamically when spinless fermions have a relativistic continuum limit. •Graphene and staggered fermions are examples of this phenomenon. •The phenomenon is intimately tied to chiral symmetry and fermion doubling. •Anomaly cancellation is a crucial feature of any valid lattice fermion action.

    Indian is one of the largest potential markets for private power. Shri P.V. Rangayya Naidu, Minister of State for Power, details the opportunities his country offers. Electricity plays a key role in the Indian economy, and its consumption is an indicator of productivity and growth. Development in the power sector has been given a high priority. Despite remarkable growth, India still faces power shortages. After rigorous review of the power sector the Government of India (GOI) is doubtful of reaching new capacity goals. It has therefore become imperature to accelerate capacity growth. To bridge the power gap the GOI is encouraging private participation. In 1991 the GOI had opened its doors to both foreign and domestic investors. Since then the legal, financial, and administrative framework has been modified to suit investors and developers. The present economic reforms pave the way for a smooth transition.

    Psychiatric disorders are common in medical inpatient and outpatient populations. As a result, internists commonly are the first to see psychiatric emergencies. As with all medical problems, a good history, including a collateral history from relatives and friends, physical and mental status examination, and appropriate laboratory tests help establish a preliminary diagnosis and treatment plan. Patients with suicidal ideation usually have multiple stressors in the environment and/or a psychiatric disorder (i.e., a major affective disorder, dysthymic disorder, anxiety or panic disorder, psychotic disorder, alcohol or drug abuse, a personality disorder, and/or an adjustment disorder). Of all patients who commit suicide, 70% have a major depressive disorder, schizophrenia, psychotic organic mental disorder, alcoholism, drug abuse, and borderline personality disorder. Patients who are at great risk have minimal supports, a history of previous suicide attempts, a plan with high lethality, hopelessness, psychosis, paranoia, and/or command self-destructive hallucinations. Treatment is directed toward placing the patient in a protected environment and providing psychotropic medication and/or psychotherapy for the underlying psychiatric problem. Other psychiatric emergencies include psychotic and violent patients. Psychotic disorders fall into two categories etiologically: those that have an identifiable organic factor causing the psychosis and those that have an underlying psychiatric disorder. Initially, it is essential to rule out organic pathology that is life-threatening or could cause irreversible brain damage. After such organic causes are ruled out, neuroleptic medication is indicated. If the patient is not agitated or combative, he or she may be placed on oral divided doses of neuroleptics in the antipsychotic range. Patients who are agitated or psychotic need rapid tranquilization with an intramuscular neuroleptic every half hour to 1 hour until the agitation and

    Among the emerging technologies for air, hazardous waste and water come new ways of looking at pollution, in both the figurative and quite literal sense. The use of microbes for remediation and pollution control is a component in many of the technologies in this report and is the focus of environmental research at many university and industry labs. Bacteria are the engines driving one featured emissions control technology: the air biofilter. Biofilters are probably more acceptable to most engineers as a soil remediation technology--such as the innovative method described in the hazardous waste section--rather than as means of cleaning off-gases, but in many cases bugs can perform the function inexpensively. The authors give the basics on this available technology. A more experimental application of microbes is being investigated as a potential quantum leap in heavy metals removal technology: bio-engineered, metal consuming plants. The effort to genetically engineer a green remediation tool is detailed in the hazardous waste section.

    Emergency contraception (EC) may help prevent pregnancy in various circumstances, such as contraceptive method failure, unprotected sexual intercourse, or sexual assault, yet it remains underused. There are 4 approved EC options in the United States. Although ulipristal acetate requires a provider's prescription, oral levonorgestrel (LNG) is available over the counter for women of all ages. The most effective method of EC is the copper intrauterine device, which can be left in place for up to 10 years for efficacious, cost-effective, hormone-free, and convenient long-term primary contraception. Ulipristal acetate tends to be more efficacious in pregnancy prevention than is LNG, especially when taken later than 72 hours postcoitus. The mechanism of action of oral EC is delay of ovulation, and current evidence reveals that it is ineffective postovulation. Women who weigh more than 75 kg or have a body mass index greater than 25 kg/m(2) may have a higher risk of unintended pregnancy when using oral LNG EC; therefore, ulipristal acetate or copper intrauterine devices are preferable in this setting. Providers are often unaware of the range of EC options or are unsure of how to counsel patients regarding the access and use of EC. This article critically reviews current EC literature, summarizes recommendations, and provides guidance for counseling women about EC. Useful tips for health care providers are provided, with a focus on special populations, including breast-feeding women and those transitioning to long-term contraception after EC use. When treating women of reproductive age, clinicians should be prepared to counsel them about EC options, provide EC appropriately, and, if needed, refer for EC in a timely manner. PMID:27261868

    Abstract Objective To determine the extent to which Nova Scotian FPs prescribe and provide emergency contraceptive pills (ECPs) and to explore their knowledge of and attitudes toward ECPs. Design Survey of Nova Scotian FPs using a modified Dillman method. Setting All regions of Nova Scotia. Participants Family physicians registered with Dalhousie University’s Division of Continuing Medical Education. Main outcome measures Sex differences in the provision of ECPs and knowledge and attitudes about the ECP Plan B. Results Of 913 eligible FPs, 155 (17.0%) participated in the survey. Respondents resembled the sampling frame closely. Most physicians (64.0%) had prescribed ECPs in the previous year (mean number of prescriptions, 4.92); only 12.9% provided ECPs in advance of need. Knowledge about Plan B was quite good, except for knowledge of the time frame for potential effectiveness; only 29.2% of respondents answered that question correctly. Respondents generally supported nonprescription availability of ECPs, but 25.0% of FPs were concerned that this could lead to less use of more effective methods of contraception, and 39.2% believed that it would encourage repeat use. Younger FPs provided ECPs more often than their older colleagues, while female respondents had better knowledge about Plan B. In multivariate analysis being younger than 40 years was marginally associated with prescribing Plan B and with prescribing any form of ECP. Conclusion Most Nova Scotian FPs provided ECPs and had generally good knowledge about and attitudes toward providing such contraception without prescription. However, FPs were poorly informed about the length of time that Plan B can be effective, which could potentially affect use when patients consult several days after unprotected sex. There were some concerns about nonprescription availability of ECPs, which could have implications for recommending it to patients. Rarely were ECPs prescribed for advance use, which might represent a lost

    Introduction and Aim: Emergency thoracotomy is performed either immediately at the scene of injury, in the emergency department or in the operating room. It aims to evacuate the pericardial tamponade, control the haemorrhage, to ease the open cardiac massage and to cross-clamp the descending thoracic aorta to redistribute blood flow and maybe to limit sub-diaphragmatic haemorrhage, bleeding and iatrogenic injury are the common risk factors. We aimed to review our experience in the field of emergency thoracotomies, identify the predictors of death, analyze the early results, detect the risk factors and asses the mortalities and their risk factors. Patients and Methods: Our hospital records of 197 patients who underwent emergency thoracotomy were reviewed. We retrospectively analyzed a piece of the extensive experience of the Mansoura University Hospitals and Mansoura Emergency Hospital; Egypt and Saudi German Hospitals; Jeddah in the last 12 years in the management of trauma cases for whom emergency thoracotomy. The aim was to analyse the early results of such cases and to detect the risk factors of dismal prognosis. Results: Our series included 197 cases of emergency thoractomies in Mansoura; Egypt and SGH; Jeddah; KSA in the last 12 years. The mean age of the victims was 28 years and ranged between 5 and 62 years. Of the 197 patients with emergency thoracotomy, the indications were both penetrating and blunt chest trauma, iatrogenic and postoperative hemodynamito a surgical cause. The commonest indication was stab heart followed by traumatic diaphragmatic ruptures. Conclusion: The results of emergency thoracotomy in our series were cooping with the results of other reports, mainly due to our aggressive measures to achieve rapid stabilization of the hemodynamic condition. We emphasize the importance of emergency medicine education programs on rapid diagnosis of traumatic injuries with early intervention, and adequate hemodynamic and respiratory support. Emergency

    New trends have emerged regarding the best minimally invasive access approaches to perform gastrointestinal surgery. However, these newer approaches are seen critically by those who demand a more strict assessment of outcomes and safety. An international panel of expert gathered at the 2014 American College of Surgeons Meeting with the goal of providing an evidence-based understanding of the real value of these approaches in gastrointestinal surgery. The panel has compared the efficacy and safety of most established approaches to gastrointestinal diseases to those of new treatment modalities: peroral esophageal myotomy vs. laparoscopic myotomy for achalasia, transgastric vs. transvaginal approach, and single-incision vs. multi-port access minimally invasive surgery. The panel found that (1) the outcome of these new approaches was not superior to that of established surgical procedures; (2) the new approaches are generally performed in few highly specialized centers; and (3) transgastric and transvaginal approaches might be safe and feasible in very experienced hands, but cost, training, operative time, and tools seem to limit their application for the treatment of common procedures such as cholecystectomy and appendectomy. Because the expected advantages of new approaches have yet to be proven in controlled trials, new approaches should be considered for adoption into practice only after thorough analyses of their efficacy and effectiveness and appropriate training.

    Emergency mask approach on Orion poses a challenge to the traditional Shuttle or Station approaches. Currently, in the case of a fire or toxic spill event, the crew utilizes open loop oxygen masks that provide the crew with oxygen to breath, but also dumps the exhaled oxygen into the cabin. For Orion, with a small cabin volume, the extra oxygen will exceed the flammability limit within a short period of time, unless a nitrogen purge is also provided. Another approach to a fire or toxic spill event is the use of a filtering emergency masks. These masks utilize some form of chemical beds to scrub the air clean of toxic providing the crew safe breathing air for a period without elevating the oxygen level in the cabin. Using the masks and a form of smoke-eater filter, it may be possible to clean the cabin completely or to a level for safe transition to a space suit to perform a cabin purge. Issues with filters in the past have been the reaction temperature and high breathing resistance. Development in a new form of chemical filters has shown promise to make the filtering approach feasible.

    A specific formulation has been approved for use in Italy for emergency contraception (EC) in 2000. As expected, marketing of this levonorgestrel (LNG) only formulation has been accompanied by an increased interest and, often, controversies leading to even strong opposition on the part of those ethically opposed to the use of any method that may act after fertilization. At present, several trials on the exact mechanism of action and safety have been conducted, giving good reason for simplifying access, providing it free or over the counter, in several European countries. EC, also known as ''the morning after pill'' or postcoital contraception, is a modality of preventing the establishment of an unwanted pregnancy after unprotected intercourse and thus, probably, of reducing the number of voluntary pregnancy terminations. Two different forms are available: the hormonal and the intrauterine. Hormonal estrogen only EC was first proposed in the 60s and in 1974 Yuzpe following his studies proposed for the first time his combined regimen, that showed better efficacy and lower side effects. More recently, a new regimen, consisting of LNG, administered alone at the dose of 1.5 mg, was introduced and found in clinical trials to be more effective than the Yuzpe regimen, if taken as early as possible, within 72 h, thereby replacing the latter in common use. Mechanism of action of both hormonal preparations used for EC is inhibiting or delaying ovulation, therefore a prefertilization action. No effect has been reported on the process of implantation nor on an ongoing pregnancy. The WHO have developed a third regimen based on the use of the selective progesterone receptor modulator (antiprogestin) Mifepristone and conducted trials with different dosages, reporting similar efficacy and safety compared to LNG. Intrauterine EC was first proposed by Lippes in 1976. It has the advantage of being effective if inserted within 5 days after unprotected intercourse and the disadvantage

    Background & Aims Bile acids (BAs) regulate energy expenditure by activating G-protein Coupled Bile Acid Receptor Gpbar1/TGR5 by cAMP-dependent mechanisms. Cholecystectomy (XGB) increases BAs recirculation rates resulting in increased tissue exposure to BAs during the light phase of the diurnal cycle in mice. We aimed to determine: 1) the effects of XGB on basal metabolic rate (BMR) and 2) the roles of TGR5 on XGB-dependent changes in BMR. Methods BMR was determined by indirect calorimetry in wild type and Tgr5 deficient (Tgr5-/-) male mice. Bile flow and BAs secretion rates were measured by surgical diversion of biliary duct. Biliary BAs and cholesterol were quantified by enzymatic methods. BAs serum concentration and specific composition was determined by liquid chromatography/tandem mass spectrometry. Gene expression was determined by qPCR analysis. Results XGB increased biliary BAs and cholesterol secretion rates, and elevated serum BAs concentration in wild type and Tgr5-/- mice during the light phase of the diurnal cycle. BMR was ~25% higher in cholecystectomized wild type mice (p <0.02), whereas no changes were detected in cholecystectomized Tgr5-/- mice compared to wild-type animals. Conclusion XGB increases BMR by TGR5-dependent mechanisms in mice. PMID:25738495

    This review focuses on the laparoscopic approach to gastrointestinal emergencies and its more recent indications. Laparoscopic surgery has a specific place in elective procedures, but that does not apply in emergency situations. In specific emergencies, there is a huge range of indications and different techniques to apply, and not all of them are equally settle. We consider that the most controversial points in minimally invasive procedures are indications in emergency situations due to technical difficulties. Some pathologies, such as oesophageal emergencies, obstruction due to colon cancer, abdominal hernias or incarcerated postsurgical hernias, are nearly always resolved by conventional surgery, that is, an open approach due to limited intraabdominal cavity space or due to the vulnerability of the bowel. These technical problems have been solved in many diseases, such as for perforated peptic ulcer or acute appendectomy for which a laparoscopic approach has become a well-known and globally supported procedure. On the other hand, endoscopic procedures have acquired further indications, relegating surgical solutions to a second place; this happens in cholangitis or pancreatic abscess drainage. This endoluminal approach avoids the need for laparoscopic development in these diseases. Nevertheless, new instruments and new technologies could extend the laparoscopic approach to a broader array of potentials procedures. There remains, however, a long way to go. PMID:26973409

    In June 1966, at the start of the Gulf Coast hurricane season, the Johnson Space Center (JSC) celebrated the opening of its new 4,000-square foot, state-of-the-art Emergency Operations Center (EOC). The new EOC has been upgraded and enhanced to support a wide spectrum of emergencies affecting JSC and neighboring communities. One of the main features of the EOC is its premier computerized dispatch center. The new system unites many of JSC's critical emergency functions into one integrated network. It automatically monitors fire alarms, security entrances, and external cameras. It contains the JSC inventory of hazardous materials, by building and room, and can call up Material Safety Data Sheets for most of the generic hazardous materials used on-site. The EOC is available for community use during area emergencies such as hurricanes and is a welcome addition to the Clear Lake/Galveston Bay Area communities' emergency response resources.

    ABSTRACT Objective: To evaluate the change in respiratory function and functional capacity according to the type of preoperative fasting. Methods: Randomized prospective clinical trial, with 92 female patients undergoing cholecystectomy by laparotomy with conventional or 2 hours shortened fasting. The variables measured were the peak expiratory flow, forced expiratory volume in the first second, forced vital capacity, dominant handgrip strength, and non-dominant handgrip strength. Evaluations were performed 2 hours before induction of anesthesia and 24 hours after the operation. Results: The two groups were similar in preoperative evaluations regarding demographic and clinical characteristics, as well as for all variables. However, postoperatively the group with shortened fasting had higher values than the group with conventional fasting for lung function tests peak expiratory flow (128.7±62.5 versus 115.7±59.9; p=0.040), forced expiratory volume in the first second (1.5±0.6 versus 1.2±0.5; p=0.040), forced vital capacity (2.3±1.1 versus 1.8±0.9; p=0.021), and for muscle function tests dominant handgrip strength (24.9±6.8 versus 18.4±7.7; p=0.001) and non-dominant handgrip strength (22.9±6.3 versus 17.0±7.8; p=0.0002). In the intragroup evaluation, there was a decrease in preoperative compared with postoperative values, except for dominant handgrip strength (25.2±6.7 versus 24.9±6.8; p=0.692), in the shortened fasting group. Conclusion: Abbreviation of preoperative fasting time with ingestion of maltodextrin solution is beneficial to pulmonary function and preserves dominant handgrip strength. PMID:26154547

  13. Emerging and re-emerging infections.

    PubMed

    Lim, V K

    1999-06-01

    An emerging infection is defined as an infection which has newly appeared in a population while a re-emerging infection is one which has existed in the past but its incidence is rapidly increasing. The reasons for the emergence and re-emergence of infections are not well understood but appear to be associated with factors that involve the pathogen, the host and the environment. These factors are often inter-related and act together in a complex manner to bring about changes in patterns of infection. Pathogens are extremely resourceful and possess mechanisms to adapt to new hosts and environments as well as to acquire new virulence traits. Host factors include herd immunity, social behaviour and demographics. Environmental factors like the climate, deforestation and new technologies have an impact on the emergence of infections. The challenge is to contain an infection when it emerges but more importantly to prevent its emergence in the first place. As the emergence of an infection is complex and multifactorial, a multidisciplinary approach is required. Health based strategies alone are insufficient. Social, economic and environmental measures and the political will to implement appropriate policies are equally important. PMID:10972048

    This research focuses on scheduling patients in emergency department laboratories according to the priority of patients' treatments, determined by the triage factor. The objective is to minimize the total waiting time of patients in the emergency department laboratories with emphasis on patients with severe conditions. The problem is formulated as a flexible open shop scheduling problem and a mixed integer linear programming model is proposed. A genetic algorithm (GA) is developed for solving the problem. Then, the response surface methodology is applied for tuning the GA parameters. The algorithm is tested on a set of real data from an emergency department. Simulation results show that the proposed algorithm can significantly improve the efficiency of the emergency department by reducing the total waiting time of prioritized patients. PMID:25214024

    Laparoscopic cholecystectomy (LC) has been recently adapted to acute cholecystitis. Major bile duct injury during LC, especially Strasberg-Bismuth classification type E, can be a critical problem sometimes requiring hepatectomy. Safety and definitive treatment without further morbidities, such as posthepatectomy liver failure, is required. Here, we report a case of severe bile duct injury treated with a stepwise approach using (99m)Tc-galactosyl human serum albumin ((99m)Tc-GSA) single-photon emission computed tomography (SPECT)/CT fusion imaging to accurately estimate liver function.A 52-year-old woman diagnosed with acute cholecystitis underwent LC at another hospital and was transferred to our university hospital for persistent bile leakage on postoperative day 20. She had no jaundice or infection, although an intraperitoneal drainage tube discharged approximately 500 ml of bile per day. Recorded operation procedure showed removal of the gallbladder with a part of the common bile duct due to its misidentification, and each of the hepatic ducts and right hepatic artery was injured. Abdominal enhanced CT revealed obstructive jaundice of the left liver and arterial shunt through the hilar plate to the right liver. Magnetic resonance cholangiopancreatography revealed type E4 or more advanced bile duct injury according to the Bismuth-Strasberg classification. We planned a stepwise approach using percutaneous transhepatic cholangiodrainage (PTCD) and portal vein embolization (PVE) for secure right hemihepatectomy and biliary-jejunum reconstruction and employed (99m)Tc-GSA SPECT/CT fusion imaging to estimate future remnant liver function. The left liver function rate had changed from 26.2 % on admission to 26.3 % after PTCD and 54.5 % after PVE, while the left liver volume rate was 33.8, 33.3, and 49.6 %, respectively. The increase of liver function was higher than that of volume (28.3 vs. 15.8 %). On postoperative day 63, the curative operation, right

    Background: Unrelieved post-operative pain may result in the physical suffering as well as multiple physiological and the psychological consequences, which may adversely affect the peri-operative outcome and contribute to increase the length of stay in hospital. Objectives: We designed this study to evaluate the effect of IV Paracetamol and Dexmedetomidine as multimodal analgesic technique on post-operative analgesia and to reduce the consumption of the systemic opioid and its adverse effects in cases of laparoscopic cholecystectomy. Materials and Methods: Eighty consenting, American society of Anesthesiologist-physical status-I (ASA-PS-I), female patients, aged 19-60 year was randomly assigned to one of the following two groups: Group P (n = 40) received IV 1 g Paracetamol infusion over 10 min pre-operatively and 6 hourly thereafter and Group D (n = 40) received IV Dexmedetomidine 1 μg/kg bolus over 10 min pre-operatively and 0.2-0.4 μg/kg/h thereafter for 24 h. Peri-operative hemodynamic variables, post-operative pain scores, and the need for rescue analgesics were recorded and compared. Results: Profiles of intra-operative hemodynamic changes were similar in both groups in respect to heart rate (HR), diastolic blood pressure, mean arterial pressure except in the systolic blood pressure where Dexmedetomidine significantly reduced it in compare to Paracetamol (P = 0.014). Post-operatively 4th h and 24th h changes in mean HR between two groups was a statistically significant (P < 0.05). Visual analog scale scores were significantly lower in the Group P compared with Group D at 8th, 16th, and 24th h (P < 0.001). Sedation score were statistically higher in the Group D compared with the Group P at post-operative 4th, 8th, 16th, and 24th h (P < 0.006). Conclusion: Adjunctive use of both Paracetamol and Dexmedetomidine infusion reduced opioid use. However, Paracetamol peri-operatively provides adequate analgesia with the less sedation whereas Dexmedetomidine provides

    Abstract Effective management of public health emergencies demands open and transparent public communication. The rationale for transparency has public health, strategic and ethical dimensions. Despite this, government authorities often fail to demonstrate transparency. A key step in bridging the gap between the rhetoric and reality is to define and codify transparency to put in place practical mechanisms to encourage open public health communication for emergencies. The authors demonstrate this approach using the example of the development and implementation process of a public health emergency information policy. PMID:19705012

    There are so many emergency issues in our daily life. Such as typhoons, tsunamis, earthquake, fires, floods, epidemics, etc. These emergencies made people lose their lives and their belongings. Every day, every hour, even every minute people probably face the emergency, so how to handle it and how to decrease its hurt are the matters people care most. If we can map it exactly before or after the emergencies; it will be helpful to the emergency researchers and people who live in the emergency place. So , through the emergency map, before emergency is occurring we can predict the situation, such as when and where the emergency will be happen; where people can refuge, etc. After disaster, we can also easily assess the lost, discuss the cause and make the lost less. The primary effect of mapping is offering information to the people who care about the emergency and the researcher who want to study it. Mapping allows the viewers to get a spatial sense of hazard. It can also provide the clues to study the relationship of the phenomenon in emergency. Color, as the basic element of the map, it can simplify and clarify the phenomenon. Color can also affects the general perceptibility of the map, and elicits subjective reactions to the map. It is to say, structure, readability, and the reader's psychological reactions can be affected by the use of color.

    2016-06-01

    The number of patients treated in hospital emergency departments in Germany has risen in recent years to approximately 20 million. This escalation also applies to the increasing numbers of patients presenting with neurological symptoms and diseases, which occur in approximately 20 % of emergency patients. In addition to patients with stroke, inflammatory or degenerative central nervous system (CNS) and peripheral nervous system (PNS) disorders who need urgent treatment, more and more patients with nonspecific complaints or conditions attend emergency departments for elective treatment, not least because timely appointments with specialist neurologists in practices could not be obtained. Neurological expertise and presence in emergency departments at the level of specialist standard are therefore indispensable for providing a professional level of treatment, which also corresponds to current legal requirements. The implementation of a generalist emergency physician in Germany, as introduced in some European countries, would mean a retrograde step for neurological expertise in emergency admission management. The discipline of neurology must work together with other emergency disciplines to improve the financing of emergency departments and provide neurologists working there with a substantive curriculum of further and continuing education in emergency-related aspects of neurology. The discipline of neurology has a responsibility to emergency patients within its range of competencies and must, therefore, strengthen and improve its role in healthcare politics and concerning organizational and personnel aspects of neurological emergencies.

  18. Defining an emerging disease.

    PubMed

    Moutou, F; Pastoret, P-P

    2015-04-01

    Defining an emerging disease is not straightforward, as there are several different types of disease emergence. For example, there can be a 'real' emergence of a brand new disease, such as the emergence of bovine spongiform encephalopathy in the 1980s, or a geographic emergence in an area not previously affected, such as the emergence of bluetongue in northern Europe in 2006. In addition, disease can emerge in species formerly not considered affected, e.g. the emergence of bovine tuberculosis in wildlife species since 2000 in France. There can also be an unexpected increase of disease incidence in a known area and a known species, or there may simply be an increase in our knowledge or awareness of a particular disease. What all these emerging diseases have in common is that human activity frequently has a role to play in their emergence. For example, bovine spongiform encephalopathy very probably emerged as a result of changes in the manufacturing of meat-and-bone meal, bluetongue was able to spread to cooler climes as a result of uncontrolled trade in animals, and a relaxation of screening and surveillance for bovine tuberculosis enabled the disease to re-emerge in areas that had been able to drastically reduce the number of cases. Globalisation and population growth will continue to affect the epidemiology of diseases in years to come and ecosystems will continue to evolve. Furthermore, new technologies such as metagenomics and high-throughput sequencing are identifying new microorganisms all the time. Change is the one constant, and diseases will continue to emerge, and we must consider the causes and different types of emergence as we deal with these diseases in the future. PMID:26470448

  20. Emergence time in forest bats: the influence of canopy closure

    NASA Astrophysics Data System (ADS)

    Russo, Danilo; Cistrone, Luca; Jones, Gareth

    2007-01-01

    The role of the forest canopy in protecting bats roosting in forest from predators is poorly known. We analysed the effect of canopy closure on emergence time in Barbastella barbastellus in a mountainous area of central Italy. We used radio-tracking to locate roosts and filmed evening emergence. Comparisons were made between roosts in open areas and those in dense forest. Median emergence time and illuminance were correlated. Moreover, from pregnancy to late lactation bats emerged progressively earlier, probably because of the exceptionally high wing loading affecting pregnant bats and the high energy demand of lactation. A significant influence of canopy closure on median emergence time was revealed after adjusting for the effects of light and reproductive state. Bats in open habitat emerged later than those roosting beneath closed canopy. In cluttered habitats, predators relying on vision may find it more difficult to detect and catch bats at light levels which would offer more chances of success when attacking prey in open habitats. Bats in dense forest are less vulnerable to predators and may take advantage of an earlier emergence by prolonging foraging. Although more vulnerable, lactating females roosting at open sites may benefit from warmer roosting conditions. Roosts in dense forest may be preferred under intense predation pressure. Forest management should favour canopy heterogeneity to provide bats with a range of roosting conditions. Our work emphasises the role of a fine-grained spatial scale in the roosting ecology of forest bats.

    Hypertension affects approximately one-third of Americans. An additional 30% are unaware that they harbor the disease. Significantly increased blood pressure constitutes a hypertensive emergency that could lead to end-organ damage. When organs such as the brain, heart, or kidney are affected, an intervention that will lower the blood pressure in several hours is indicated. Several pharmacologic options are available for treatment, with intravenous antihypertensive therapy being the cornerstone, but there is no standard of care. Careful consideration of each patient's specific complaint, history, and physical examination guides the emergency physician through the treatment algorithm. PMID:26226865

    Acute medical care in hospital emergency departments has experienced rapid development in recent years and gained increasing importance not only from a professional medical point of view but also from an economic and health policy perspective. The present article therefore provides an update on the situation of emergency departments in Germany. Care in emergency departments is provided with an increasing tendency to patients of all ages presenting with varying primary symptoms, complaints, illnesses and injury patterns. In the process, patients reach the emergency department by various routes and structural provision. Cross-sectional communication and cooperation, prioritization and organization of emergency management and especially medical staff qualifications increasingly play a decisive role in this process. The range of necessary knowledge and skills far exceeds the scope of prehospital medical emergency care and the working environment differs substantially. In addition to existing structural and economic problems, the latest developments, as well as future proposals for the design of in-hospital emergency medical care in interdisciplinary emergency departments are described.

    Background Establishment of laparoscopic cholecystectomy as an outpatient procedure has accentuated the clinical importance of reducing early postoperative pain, as well as postoperative nausea and vomiting (PONV). We therefore planned to evaluate the role of a multimodal approach in attenuating these problems. Methods One hundred and twenty adult patients of ASA physical status I and II and undergoing elective laparoscopic cholecystectomy were included in this prospective, randomized, placebo-controlled study. Patients were divided into four groups of 30 each to receive methylprednisolone 125 mg intravenously or etoricoxib 120 mg orally or a combination of methylprednisolone 125 mg intravenously and etoricoxib 120 mg orally or a placebo 1 hr prior to surgery. Patients were observed for postoperative pain, fentanyl consumption, PONV, fatigue and sedation, and respiratory depression. Results were analyzed by the ANOVA, a Chi square test, the Mann Whitney U test and by Fisher's exact test. P values of less than 0.05 were considered to be significant. Results Postoperative pain and fentanyl consumption were significantly reduced by methylprednisolone, etoricoxib and their combination when compared with placebo (P<0.05). The methylprednisolone + etoricoxib combination caused a significant reduction in postoperative pain and fentanyl consumption as compared to methylprednisolone or etoricoxib alone (P<0.05); however, there was no significant difference between the methylprednisolone and etoricoxib groups (P>0.05). The methylprednisolone and methylprednisolone + etoricoxib combination significantly reduced the incidence and severity of PONV and fatigue as well as the total number of patients requiring an antiemetic treatment compared to the placebo and etoricoxib (P<0.05). Conclusions A preoperative single-dose administration of a combination of methylprednisolone and etoricoxib reduces postoperative pain along with fentanyl consumption, PONV, antiemetic requirements and

  19. Predicting Emergency Department Visits

    2016-01-01

    High utilizers of emergency departments account for a disproportionate number of visits, often for nonemergency conditions. This study aims to identify these high users prospectively. Routinely recorded registration data from the Indiana Public Health Emergency Surveillance System was used to predict whether patients would revisit the Emergency Department within one month, three months, and six months of an index visit. Separate models were trained for each outcome period, and several predictive models were tested. Random Forest models had good performance and calibration for all outcome periods, with area under the receiver operating characteristic curve of at least 0.96. This high performance was found to be due to non-linear interactions among variables in the data. The ability to predict repeat emergency visits may provide an opportunity to establish, prioritize, and target interventions to ensure that patients have access to the care they require outside an emergency department setting.

    Background: Postoperative nausea and vomiting (PONV) are common and potentially distressing adverse events (AEs) associated with surgery and anesthesia. In patients undergoing laparoscopic cholecystectomy (LC) without antiemetic prophylaxis, the incidence of PONV can be as high as 72%. Objective: The aim of this study was to investigate the prophylactic antiemetic effects of ondansetron and granisetron in patients undergoing LC when these agents are administered before the end of surgery. Methods: Patients classified by the American Society of Anesthesiologist's physical status as I or II who were scheduled for elective LC were included in this randomized, double-blind, placebo-controlled study. Anesthesia was induced with thiopental 5 mg/kg and fentanyl 2 μg/kg, and was maintained with isoflurane 1% to 3% in 50% oxygen and 50% nitrous oxide and fentanyl as needed. Approximately 20 to 30 minutes before the end of the surgery, the patients randomly received either IV ondansetron 100 μg/kg (group O), IV granisetron 40 μg/kg (group G), or normal saline (group P). Plasma levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined preoperatively and 24 hours postoperatively. The patients were observed for 24 hours for PONV and other possible AEs. Postoperative pain intensity was determined using a 10-cm visual analogue scale. Four-point satisfaction scores were determined at 24 hours. Results: Ninety patients (69 women, 21 men) participated in the study. Demographic characteristics and operative data (duration of surgery and anesthesia and amount of intraoperative fentanyl) were similar in the 3 groups. The only AE reported by patients during the 24-hour observation period was nonsevere headache. The number of patients experiencing headache was similar in group P, group O, and group G (10 [33%] patients, 6 [20%], and 10 [33%], respectively). No significant changes were found in presurgical and postsurgical plasma levels of ALT and

    Spurred by the publication of Massachusetts Institute of Technology OpenCourseWare in 2002, the open educational resources (OER) movement, which has rapidly expanded and captured the imagination and energy of millions of creators and users throughout the world, now faces many opportunities and substantial challenges as it moves to become an integral part of the world's educational environment. The confluence of the Web and a spirit of sharing intellectual property have fueled a worldwide movement to make knowledge and education materials open to all for use. OER are content (courses, books, lesson plans, articles, etc.), tools (virtual laboratories, simulations, and games), and software that support learning and educational practice. OER are free on the Web, and most have licenses that allow copyright holders to retain ownership while providing specified rights for use in original and modified forms. At the least, OER have helped to level the distribution of knowledge across the world. A second promise of OER is to help transform educational practices.

    Emergency departments use has been constantly increasing over the world. Overcrowding is defined as a situation which compromises patient safety because of delayed cares. This situation is often reached. Emergency departments have to continuously improve their organization to be able to ensure the same quality of care to a higher number of patients. Thus a good organization is essential: it doesn't always avoid overcrowding. The rest of the hospital has to be involved in this process to ensure efficiency. We examine the various interventions and procedures that can be found in medical literature for improving patients flow and management in emergency departments. PMID:25842427

    Travels, migration and circulation of goods facilitate the emergence of new infectious diseases often unrecognized outside endemic areas. Most of emerging infections are of viral origin. Muscular Sarcocystis infection, an acute illness acquired during short trips to Malaysia, and Chagas disease, a chronic illness with long incubation period found among Latin American migrants, are two very different examples of emerging parasitic diseases. The former requires a preventive approach for travelers going to Malaysia and must be brought forth when they return with fever, myalgia and eosinophilia, while the latter requires a proactive attitude to screen Latin American migrant populations that may face difficulties in accessing care.

    In most instances, delayed emergence from anesthesia is attributed to residual anesthetic or analgesic medications. However, delayed emergence can be secondary to unusual causes and present diagnostic dilemmas. Data from clinical studies is scarce and most available published material is comprised of case reports. In this review, we summarize and discuss less common and difficult to diagnose reasons for delayed emergence and present cases from our own experience or reference published case reports/case series. The goal is to draw attention to less common reasons for delayed emergence, identify patient populations that are potentially at risk and to help anesthesiologists identifying a possible cause why their patient is slow to wake up.

The lights -- four floodlights which provide 2,000 watts of daytime equivalent visibility and a high-intensity flashing beacon can be elevated 10 feet above the roof of an emergency vehicle by means of an extendible mast. The higher elevation expands the effective radius of the floodlights and increases the beacon's visibility to several miles affording extra warning time to approaching traffic. When not in use, the light can be retracted into the compact rooftop housing. Stem-Lite also includes a generator which can serve to power such emergency equipment as pumps and drills, and a dashboard-mounted control panel for switching the lights and extending or retracting the mast.

  19. Cretaceous carbonate platforms - emerging concepts and open problems

    SciTech Connect

    Schlager, W.

    1988-02-01

    The Cretaceous is a time of both spectacular growth and abrupt demise of carbonate platforms. Tectono-eustatic rise of sea level coupled with sediment-starvation in the ocean basins produced exceptionally high platforms. Because platform slopes steepen with height whereas siliciclastic slopes do not, the flanks of these high-rising platforms were onlapped by more gently dipping siliciclastics when the platforms ceased to grow. Future studies will have to separate these termination unconformities from the geometrically similar lowstand unconformities. Simultaneously, a carbonate sea level curve should be constructed solely from the record of the platform tops and compared with the onlap curves of seismic stratigraphy. The abrupt demise of Cretaceous platforms is even more remarkable than their rapid growth. In the Valanginian, the Aptian, the late Albian, the late Cenomanian, and the Turonian, platforms were drowned or reduced in size. The mid-Cretaceous events affected platforms in all major oceans and point to a global crisis of carbonate platforms, probably caused by environmental change such as oceanic anoxic events. A worldwide study is required to date these events and search for their causes in the record of life, climate, ocean circulation, and ocean chemistry. A third field of future research is the record of paleoclimate in the tidal flats and lagoons of the platforms on the northern and southern margins of Tethys. Climate modeling has identified this zone as a particularly sensitive switch in the ocean-atmosphere system of the Cretaceous.

  2. Emergency Communications Console

    1978-01-01

    NASA has applied its communications equipment expertise to development of a communications console that provides, in a compact package only slightly larger than an electric typewriter, all the emergency medical services communications functions needed for a regional hospital. A prototype unit, built by Johnson Space Center, has been installed in the Odessa (Texas) Medical Center Hospital. The hospital is the medical control center for the 17-county Permian Basin Emergency Medical System in west Texas. The console project originated in response to a request to NASA from the Texas governor's office, which sought a better way of providing emergency medical care in rural areas. Because ambulance travel time is frequently long in remote areas of west Texas, it is important that treatment begin at the scene of the emergency rather than at the hospital emergency room. A radio and telephone system linking ambulance emergency technicians and hospital staff makes this possible. But earlier equipment was complex, requiring specialized operators. A highly reliable system was needed to minimize breakdowns and provide controls of utmost simplicity, so that the system could be operated by physicians and nurses rather than by communications specialists. The resulting console has both radio and telephone sections. With the radio equipment, hospital personnel can communicate with ambulance drivers and paramedics, receive incoming electrocardiagrams, consult with other hospitals, page hospital staff and set up a radio-to-telephone "patch." The telephone portion of the system includes a hotline from the Permian Basin Emergency Medical Service's resource control center, an automatic dialer for contacting special care facilities in the Permian Basin network, a hospital intercom terminal and a means of relaying cardioscope displays and other data between hospitals. The integrated system also provides links with local disaster and civil defense organizations and with emergency "Dial 911

  6. OpenARC: Extensible OpenACC Compiler Framework for Directive-Based Accelerator Programming Study

    Lee, Seyong; Vetter, Jeffrey S

    2014-01-01

    Directive-based, accelerator programming models such as OpenACC have arisen as an alternative solution to program emerging Scalable Heterogeneous Computing (SHC) platforms. However, the increased complexity in the SHC systems incurs several challenges in terms of portability and productivity. This paper presents an open-sourced OpenACC compiler, called OpenARC, which serves as an extensible research framework to address those issues in the directive-based accelerator programming. This paper explains important design strategies and key compiler transformation techniques needed to implement the reference OpenACC compiler. Moreover, this paper demonstrates the efficacy of OpenARC as a research framework for directive-based programming study, by proposing and implementing OpenACC extensions in the OpenARC framework to 1) support hybrid programming of the unified memory and separate memory and 2) exploit architecture-specific features in an abstract manner. Porting thirteen standard OpenACC programs and three extended OpenACC programs to CUDA GPUs shows that OpenARC performs similarly to a commercial OpenACC compiler, while it serves as a high-level research framework.

  7. Open Inflation

    NASA Astrophysics Data System (ADS)

    Hawking, S. W.

    In February this year, Neil Turok and I proposed a new model for inflation. The distinctive feature was that it produced an infinite, open universe, yet it satisfied the no boundary condition and came from an instanton of finite size, with a mass of the order of one gram. Our paper aroused a lot of interest, as shown by 37 citations on HEP-TH, but it brought a lot of opposition. This centered on three features of our model.First, we were attacked for using the no boundary proposal. People like Linde and Vilenkin, claimed that one should use the quantum tunneling wave function instead.Second, we were criticized because our instanton contained a singularity. It was said this was contrary to the spirit of the no boundary proposal; that the singularity would be naked and would make the universe non predictable.Third, we invoked the anthropic principle, to avoid the model predicting a totally empty universe. We were attacked both for using anthropic arguments, and for the very low value for the density of the universe, that they seemed to lead to.In this talk, I will describe the open inflation model that Neil and I proposed, and answer some of the objections that have been raised.

  8. Bispectrum from open inflation

    We calculate the bispectrum of primordial curvature perturbations, ζ, generated during ''open inflation.'' Inflation occurs inside a bubble nucleated via quantum tunneling from the background false vacuum state. Our universe lives inside the bubble, which can be described as a Friedmann-Lemaȋtre-Robertson-Walker (FLRW) universe with negative spatial curvature, undergoing slow-roll inflation. We pay special attention to the issue of an initial state for quantum fluctuations. A ''vacuum state'' defined by a positive-frequency mode in de Sitter space charted by open coordinates is different from the Euclidean vacuum (which is equivalent to the so-called ''Bunch-Davies vacuum'' defined by a positive-frequency mode in de Sitter space charted by flat coordinates). Quantum tunneling (bubble nucleation) then modifies the initial state away from the original Euclidean vacuum. While most of the previous study on modifications of the initial quantum state introduces, by hand, an initial time at which the quantum state is modified as well as the form of the modification, an effective initial time naturally emerges and the form is fixed by quantum tunneling in open inflation models. Therefore, open inflation enables a self-consistent computation of the effect of a modified initial state on the bispectrum. We find a term which goes as (ζ{sub k{sub 1}}ζ{sub k{sub 2}}ζ{sub k{sub 3}})∝1/k{sub 1}{sup 2}k{sub 3}{sup 4} in the so-called squeezed configurations, k{sub 3} << k{sub 1} ≈ k{sub 2}, in agreement with the previous study on modifications of the initial state. The bispectrum in the exact folded limit, e.g., k{sub 1} = k{sub 2}+k{sub 3}, is also enhanced and remains finite. However, these terms are exponentially suppressed when the wavelength of ζ is smaller than the curvature radius of the universe. The leading-order bispectrum is equal to the usual one from single-field slow-roll inflation; the terms specific for open inflation arise only in the sub-leading order

    2013-01-01

    Pluripotent stem cells can be derived from embryos or induced from adult cells by reprogramming. They are unique from any other stem cell in that they can give rise to all cell types of the body. Recent findings indicate that a particularly open chromatin state contributes to maintenance of pluripotency. Two emerging principles are that: specific factors maintain a globally open chromatin state that is accessible for transcriptional activation; and other chromatin regulators contribute locally to the silencing of lineage-specific genes until differentiation is triggered. These same principles may apply during reacquisition of an open chromatin state upon reprogramming to pluripotency, and during de-differentiation in cancer. PMID:21179060

    It's no easy task to identify strategies for entering new international markets or to decide which countries to do business with. Many firms simply go with what they know-and fall far short of their goals. Part of the problem is that emerging markets have "institutional voids": They lack specialized intermediaries, regulatory systems, and contract-enforcing methods. These gaps have made it difficult for multinationals to succeed in developing nations; thus, many companies have resisted investing there. That may be a mistake. If Western companies don't come up with good strategies for engaging with emerging markets, they are unlikely to remain competitive. Many firms choose their markets and strategies for the wrong reasons, relying on everything from senior managers' gut feelings to the behaviors of rivals. Corporations also depend on composite indexes for help making decisions. But these analyses can be misleading; they don't account for vital information about the soft infrastructures in developing nations. A better approach is to understand institutional variations between countries. The best way to do this, the authors have found, is by using the five contexts framework. The five contexts are a country's political and social systems, its degree of openness, its product markets, its labor markets, and its capital markets. By asking a series of questions that pertain to each ofthe five areas, executives can map the institutional contexts of any nation. When companies match their strategies to each country's contexts, they can take advantage of a location's unique strengths. But first firms should weigh the benefits against the costs. If they find that the risks of adaptation are too great, they should try to change the contexts in which they operate or simply stay away. PMID:15938439

Recently described pathogens, such as Escherichia coli O157:H7 and the epidemic strain of Salmonella serotype Typhimurium Definitive Type 104 (which is resistant to at least five antimicrobial drugs), have become important public health problems. Well-recognized pathogens, such as Salmonella serotype Enteritidis, have increased in prevalence or become associated with new vehicles. Emergence in foodborne diseases is driven by the same forces as emergence in other infectious diseases: changes in demographic characteristics, human behavior, industry, and technology; the shift toward a global economy; microbial adaptation; and the breakdown in the public health infrastructure. Addressing emerging foodborne diseases will require more sensitive and rapid surveillance, enhanced methods of laboratory identification and subtyping, and effective prevention and control.

    Many compounds, when absorbed or ingested, can cause harm to animals and people. Veterinarians are commonly faced with companion animals that have been exposed to these harmful compounds. Most poisonings are the result of curious exploration by the pet and a quest to taste everything in their path. Some poisonings are the result of malice, and many simply result from owner ignorance when pets are given medications without regard to dose or compatibility. It is the responsibility of the emergency clinician encountering these cases to prevent further exposure to the poison, enhance its elimination, and provide supportive and antidotal care. Antidotes when available are of little value if the animal has lost any vital functions. It is the purpose of this article to focus on the emergency management of intoxications by reviewing the general principles of triage and emergency care, and to discuss available procedures to stop the exposure, prevent further absorption, and hasten elimination of poisons from the patients body.

    Hypertension is one of the most common medical problems affecting approximately 1 billion individuals worldwide. Severe hypertension that is a potentially life-threatening condition refers to a hypertensive crisis. Severe hypertension is further classified into hypertensive emergencies or hypertensive urgencies. Hypertensive emergency refers to a severe hypertension that is associated with new or progressive end-organ damage. In these clinical situations, blood pressure should be reduced immediately to prevent or minimize organ dysfunction. Hypertensive urgency refers to severe hypertension without evidence of new or worsening end-organ injury. Blood pressure can be lowered less rapidly in this condition. In this review article it is discussed about clinical assessment of patients under these conditions, evaluating neurological, cardiovascular, renal end-organ damage; how much blood pressure should be lowered, which medication should be used to lower blood pressure, treating hypertensive emergencies and urgencies; and management of specific conditions (acute intracranial events, acute left ventricular dysfunction etc).

    Phase transitions are well defined in physics through concepts such as spontaneous symmetry breaking, order parameter, entropy, and critical exponents. But emergence --- also exhibiting whole-part relations (such as top-down influence), unpredictability, and insensitivity to microscopic detail --- is a loosely-defined concept being used in many disciplines, particularly in psychology, biology, philosophy, as well as in physics[1,2]. I will review the concepts of emergence as used in the various fields and consider the extent to which the methods of phase transitions can clarify the usefulness of the concept of emergence both within the discipline of physics and beyond.1.

    This paper will talk about the technologies that have been emerging over the 25 years since the Human Vision and Electronic Imaging conference began that the conference has been a part of, and that have been a part of the conference, and will look at those technologies that are emerging today, such as social networks, haptic technologies, and still emerging imaging technologies, and what we might look at for the future.Twenty-five years is a long time, and it is not without difficulty that we remember what was emerging in the late 1980s. Yet to be developed: The first commercial digital still camera was not yet on the market, although there were hand held electronic cameras. Personal computers were not displaying standardized images, and image quality was not something that could be talked about in a standardized fashion, if only because image compression algorithms were not standardized yet for several years hence. Even further away were any standards for movie compression standards, there was no personal computer even on the horizon which could display them. What became an emergent technology and filled many sessions later, image comparison and search, was not possible, nor the current emerging technology of social networks- the world wide web was still several years away. Printer technology was still devising dithers and image size manipulations which would consume many years, as would scanning technology, and image quality for both was a major issue for dithers and Fourier noise.From these humble beginnings to the current moves that are changing computing and the meaning of both electronic devices and human interaction with them, we will see a course through the changing technology that holds some features constant for many years, while others come and go.

    Fluorescent proteins (FPs), such as the Aequorea jellyfish green FP (GFP), are firmly established as fundamental tools that enable a wide variety of biological studies. Specifically, FPs can serve as versatile genetically encoded markers for tracking proteins, organelles, or whole cells, and as the basis for construction of biosensors that can be used to visualize a growing array of biochemical events in cells and tissues. In this review we will focus on emerging applications of FPs that represent unprecedented new directions for the field. These emerging applications include new strategies for using FPs in biosensing applications, and innovative ways of using FPs to manipulate protein function or gene expression. PMID:26043278

    Several severe radiological emergencies were reviewed to determine the likely range of conditions which must be coped with by a mobile teleoperator designed for emergencies. The events reviewed included accidents at TMI (1978), SL-1 (1961), Y-12 (1958), Bethesda (1982), Chalk River (1952 and 1958), Lucens (1969). The important conditions were: radiation fields over 10,000 R/h, severe contamination, possible critical excursion, possible inert atmosphere, temperatures from 50/sup 0/C to -20/sup 0/C, 100% relative humidity, 60-cm-high obstacles, stairs, airlocks, darkness, and lack of electric power.

    Prompt identification and treatment of life-threatening oncological conditions is of utmost importance and should always be included in the differential diagnosis. Oncological emergencies can have a myriad of presentations ranging from mechanical obstruction due to tumor growth to metabolic conditions due to abnormal secretions from the tumor. Notably, hematologic and infectious conditions may complicate the presentation of oncological emergencies. Advanced testing and imaging is generally required to recognize these serious presentations of common malignancies. Early diagnosis and treatment of these conditions can significantly affect the patient's clinical outcome. PMID:23873016

    Salivary gland disorders are uncommon in the emergency department setting. Given the vast differential that spans infectious, autoimmune, neoplastic, and metabolic processes, they can pose a diagnostic challenge even to skilled clinicians. There is a paucity of evidence-based data regarding the management of these disorders with frequent incongruence between specific sources. Although by no means exhaustive or absolute, this article reconciles existing literature and serves as a concise and informative guide to salivary gland disorders encountered by the emergency care practitioner.

    As complementary metal-oxide-semiconductor field-effect transistors (CMOS FET) are being scaled to ever smaller sizes by the semiconductor industry, the demand is growing for emerging logic devices to supplement CMOS in various special functions. Research directions and concepts of such devices are overviewed. They include tunneling, graphene based, spintronic devices etc. The methodology to estimate future performance of emerging (beyond CMOS) devices and simple logic circuits based on them is explained. Results of benchmarking are used to identify more promising concepts and to map pathways for improvement of beyond CMOS computing.

    This paper describes the development of child and adolescent mental health emergency services in Macedonia since 1993. The evolution of services through the Mental Crisis Centre for Children and Adolescents, funded by the Open Society Institute, and located in six cities is outlined. The paper also defines traditional services, the nature of child mental health emergencies, the evaluation process, follow-up care and training and supervision. It concludes with concern that the mental health emergency system is not sufficient to meet the needs of the child and adolescent population, particularly in the face of the Kosovar refugee crisis. Recommendations for the future are made. PMID:11508566

    This paper presents our idea to introduce data locality feature into OpenMP. Given the facts that the memory systems are hierarchical while OpenMP is at, we believe that it is important to introduce new features to OpenMF to provide Open MP programmer capability to manage the data layout and align tasks and data as close as possible in modern architectures. We present the syntax and examples of the proposed features in this paper, and hope to enable further discussion of useful language features to keep OpenMP scalable in emerging architectures.

    2015-01-01

    Abdominal pain, nausea, and vomiting are common presenting symptoms among adult patients seeking care in the emergency department, and, with the increased use of computed tomography (CT) to image patients with these complaints, radiologists will more frequently encounter a variety of emergent gastric pathologic conditions on CT studies. Familiarity with the CT appearance of emergent gastric conditions is important, as the clinical presentation is often nonspecific and the radiologist may be the first to recognize gastric disease as the cause of a patient's symptoms. Although endoscopy and barium fluoroscopy remain important tools for evaluating patients with suspected gastric disease in the outpatient setting, compared with CT these modalities enable less comprehensive evaluation of patients with nonspecific complaints and are less readily available in the acute setting. Endoscopy is also more invasive than CT and has greater potential risks. Although the mucosal detail of CT is relatively poor compared with barium fluoroscopy or endoscopy, CT can be used with the appropriate imaging protocols to identify inflammatory conditions of the stomach ranging from gastritis to peptic ulcer disease. In addition, CT can readily demonstrate the various complications of gastric disease, including perforation, obstruction, and hemorrhage, which may direct further clinical, endoscopic, or surgical management. We will review the normal anatomy of the stomach and discuss emergent gastric disease with a focus on the usual clinical presentation, typical imaging appearance, and differentiating features, as well as potential imaging pitfalls.

    The emergence and re-emergence of viral infections is an ongoing process. Large-scale vaccination programmes led to the eradication or control of some viral infections in the last century, but new viruses are always emerging. Increased travel is leading to a rise in the importation of exotic infections such as dengue and hepatitis E, but also of hepatitis A, which is no longer endemic. Apart from import diseases new viruses have appeared (Nipah-virus and transfusion-transmitted virus). Existing viruses may suddenly cause more severe diseases, e.g. infection by enterovirus 71. The distribution area of a virus may change, e.g. in case of West Nile virus, an Egyptian encephalitis virus that appears to have established itself in the USA. Furthermore, there is no such thing as a completely new virus; it is always an existing virus that has adapted itself to another host or that was already present in humans but has only recently been discovered. A number of factors facilitate the emergence of new infectious diseases. These include intensive animal husbandry and the transport of animals. The unexpected appearance of West Nile virus in the western hemisphere was possibly due to animal transportation. PMID:11305210

  16. Emergency Response Synchronization Matrix

    Energy Science and Technology Software Center (ESTSC)

    1999-06-01

    An emergency response to a disaster is complex, requiring the rapid integration, coordination, and synchronization of multiple levels of governmental and non-governmental organizations from numerous jurisdictions into a unified community response. For example, a community’s response actions to a fixed site hazardous materials incident could occur in an area extending from an on-site storage location to points 25 or more miles away. Response actions are directed and controlled by local governments and agencies situated withinmore » the response area, as well as by state and federal operaticns centers quite removed from the area of impact. Time is critical and the protective action decision-making process is greatly compressed. The response community must carefully plan and coordinate response operations in order to have confidence that they will be effectively implemented when faced with the potentially catastrophic nature of such releases. A graphical depiction of the entire response process via an emergency response synchronization matrix is an effective tool in optimizing the planning, exercising, and implementation of emergency plans. This system—based approach to emergency planning depicts how a community organizes its response tasks across space and time in relation to hazard actions. It provides the opportunity to make real—time adjustments as necessary for maximizing the often limited resources in protecting area residents. A response must involve the entire community and must not be limited by individual jurisdictions and organizations acting on their own without coordination, integration, and synchronization.« less

    There are abundant cases of obstetric emergencies demanding prompt intervention. Emergency cesarean sections are classified into stable, urgent and immediate surgeries, although there is significant overlap between three groups. Stable emergency cesarean sections are performed in patients with stable maternal and fetal physiology, but who need surgery before unstability occurs. Urgent cesarean sections refer to situations in which maternal and/or fetal physiology is unstable, whereas the immediate cesarean section is used for life-threatening condition such as sustained fetal bradycardia, maternal cardiopulmonary arrest. In most cases the key to proper management is the prompt communication between obstetricians and anesthesiologists. Anesthesiologists must have a clear understanding of certain obstetric emergencies. In the event of sustained fetal bradycardia caused by placental abruption, cord prolapse, uterine rupture etc, delivery by immediate cesarean section within 25 minutes improve long-term neonatal neurologic outcome. Although cardiopulmonary arrest in pregnancy is very uncommon, peripartum cesarean section should be considered within 5 minutes not only for maternal resuscitation but for neonatal survival. Only a well-coordinated teamwork of all involved specialities will guarantee optimal prognosis of mother and fetus. PMID:23012828
