To compare three ports laparoscopic cholecystectomy and four ports laparoscopic cholecystectomy in terms of complications, time taken to complete the procedure, hospital stay and cost effectiveness in local perspective. Methodology: This randomized control trial included 60 patients who underwent elective laparoscopic cholecystectomy at Department of Surgery, Pakistan Institute of Medical Sciences, Islamabad, Pakistan from January 2013 to June 2013. These patients were randomized on computer generated table of random numbers into group A and Group B. In Group A patients four ports were passed to perform laparoscopic cholecystectomy and in Group B patients three ports were passed to perform the procedure. Results: The mean age in both groups was 44 years (range 18-72). Three ports laparoscopic cholecystectomy (43 min) took less time to complete than four ports laparoscopic cholecystectomy (51 min). Patients in three ports laparoscopic cholecystectomy experienced less pain as compared to four ports group. The total additional analgesia requirement in 24 hours calculated in milligrams was less in three port laparoscopic cholecystectomy group as compared four port laparoscopic cholecystectomy group. The mean hospital stay in three port laparoscopic cholecystectomy group is 25 hours while the mean hospital stay in the four port laparoscopic cholecystectomy group is 28 hours. Conclusion: Three ports laparoscopic cholecystectomy is safe and effective procedure and it did not compromise the patient safety. (author)

The journey from conventional "open" operations to truly "minimally invasive" operations naturally includes progression from operations involving multiple trocars and multiple incisions to operations involving access through the umbilicus alone. Laparoscopic operations through the umbilicus alone, laparoendoscopic single site surgery (LESS), offer improved cosmesis and hopes for less pain and improved recovery. This study was undertaken to evaluate our initial experience with LESS cholecystectomy and to compare our initial experience to concurrent outcomes with more conventional multiport, multi-incision laparoscopic cholecystectomy. All patients referred for cholecystectomy over a 6-month period were offered LESS. Outcomes, including blood loss, operative time, complications, and length of stay were recorded. Outcomes with our first LESS cholecystectomies were compared to an uncontrolled group of concurrent patients undergoing multiport, multi-incision laparoscopic cholecystectomy at the same hospital by the same surgeon. Twenty-nine patients of median age 50 years undergoing LESS cholecystectomy from November 2007 until May 2008 were compared to 29* patients, median age 48 years, undergoing standard multiport, multiple-incision laparoscopic cholecystectomy over the same time period. Median operative time for patients undergoing LESS cholecystectomy was 72 min and was not different from that of patients undergoing multiport, multi-incision laparoscopic cholecystectomy (p = 0.81). Median length of hospital stay was 1.0 day for patients undergoing LESS cholecystectomy and was not different from patients undergoing standard laparoscopic cholecystectomy (p = 0.46). Operative estimated blood loss was less than 100 cc for all patients. No patients undergoing attempted LESS cholecystectomy had conversions to "open" operations; two patients had an additional trocar(s) placed distant from the umbilicus to aid in exposure. Three patients undergoing LESS cholecystectomy had

The revised Tokyo Guidelines include criteria for determining the severity of acute cholecystitis with treatment algorithms based on severity. The aim of this study was to investigate the relationship of the revised Tokyo Guidelines severity grade to clinical outcomes of cholecystectomy for acute cholecystitis. We identified 66 patients with acute cholecystitis from a prior study of difficult cholecystectomy cases. We examined the relationship between severity grade and multiple variables related to perioperative and postoperative outcomes. A more severe revised Tokyo Guidelines grade was associated with a higher number of complications (p = 0.03) and a higher severity of complications (p = 0.01). Severity grade did not predict operative time, estimated blood loss, intensive care unit admission or length of stay. Compared to planned open cholecystectomy, intended laparoscopic cholecystectomy was associated with significantly fewer total and Clavien-Dindo grade 3 complications, fewer intensive care unit admissions, and shorter length of stay (p values range from 0.03 to < 0.0001). In technically difficult operations for acute cholecystitis, the revised Tokyo guidelines severity grade correlates with the number and severity of complications. However, intended performance of laparoscopic cholecystectomy rather than open cholecystectomy in difficult operations predicts broader beneficial outcomes than severity grade.

Open cholecystectomy is associated with considerable morbidity and mortality in cirrhotic patients. Laparoscopic cholecystectomy may offer a better option because of the magnification available and the availability of newer instruments like the ultrasonic shears. We present our experience of 265 laparoscopic cholecystectomies and attempt to identify the difficulties encountered in this group of patients. Between 1991 and 2005, 265 cirrhotic patients of Child-Pugh Classification A and B, with symptomatic gallstones, were subjected to laparoscopic cholecystectomy. We describe here our tailored approach and our techniques of subtotal cholecystectomy. Features of acute cholecystitis were present in 35.1% of the patients, and 64.9% presented with chronic cholecystitis. In 81.5% of the patients, the diagnosis of cirrhosis was established preoperatively. In 8.3% of the patients, a fundus first method was adopted when the hilum could not be approached despite additional ports. Modified subtotal cholecystectomy was performed in a total of 206 patients. Mean operative time in the subtotal cholecystectomy group was 72 minutes; in the standard group, it was 41 minutes. There was no mortality. In 15% of patients, postoperative deterioration in liver function occurred. Worsening of ascites, port site infection, port site bleeding, intraoperative hemorrhage, bilious drainage, and stone formation in the remnant were the other complications encountered. Laparoscopic cholecystectomy is a safe and effective treatment for calculous cholecystitis in cirrhotic patients. Appropriate modification of subtotal cholecystectomy should be practiced, depending on the risk factors present, to avoid complications.

As the cost of health care is subjected to increasingly greater scrutiny, the assessment of new technologies must include the surgical value (SV) of the procedure. Surgical value is defined as outcome divided by cost. The cost and outcome of 50 consecutive traditional (4-port) laparoscopic cholecystectomies (TLC) were compared with 50 consecutive, nontraditional laparoscopic cholecystectomies (NTLC), between October 2012 and February 2014. The NTLC included SILS (n = 11), and robotically assisted single-incision cholecystectomies (ROBOSILS; n = 39). Our primary outcomes included minimally invasive gallbladder removal and same-day discharge. Thirty-day emergency department visits or readmissions were evaluated as a secondary outcome. The direct variable surgeon costs (DVSC) were distilled from our hospital cost accounting system and calculated on a per-case, per item basis. The average DVSC for TLC was $929 and was significantly lower than NTLC at $2,344 (p day discharge. There were no differences observed in secondary outcomes in 30-day emergency department visits (TLC [2%] vs NTLC [6%], p = 0.61) or readmissions (TLC [4%] vs NTLC [2%], p > 0.05), respectively. The relative SV was significantly higher for TLC (1) compared with NTLC (0.34) (p < 0.05), and SILS (0.66) and ROBOSILS (0.36) (p < 0.05). Nontraditional, minimally invasive gallbladder removal (SILS and ROBOSILS) offers significantly less surgical value for elective, outpatient gallbladder removal.

Hamid Reza Hemati

2008-11-01

Full Text Available Introduction: Wound infection is one of the most common complications of surgical procedures.At present, different procedures are used to reduce wound infection including prophylactic antibiotics.Since laparoscopy controls the most sources of wound infection such as mechanical factors, the role ofprophylactic antibiotic therapy may be in doubt. In this study, we evaluated the antibiotic effects inprevention of wound infection in laparoscopic cholecystectomy.Methods and Materials: In this double-blind clinical trial study, patients who were candidate forlaparoscopic cholecystectomy were divided randomly into two groups: antibiotic receivers (38patients and placebo (Normal Saline receivers (32 patients group. The patients were visited in 24hours, 4-7, 10-15 and 30 days after surgery for wound infection and then 2 groups compared.Results: The study showed that there were no significant differences between two groups withrespect to age, body mass index and smoking. In addition, no wound infection was observed in first 24hours, 4-7, 10-15 and 30 days after operation in both groups.Conclusion: The findings showed that prophylactic antibiotic therapy in laparoscopiccholecystectomy has no effect on the incidence of wound infection. Therefore, it is suggested thatprophylactic antibiotic therapy does not use in laparoscopic cholecystectomy because of producingantibiotic resistance, unnecessary complications and also reducing economical costs.

Full Text Available Abstract 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 Conclusion Laparoscopic cholecystectomy is performed on patients having a lower mortality risk than the general Swedish population. Patients with open cholecystectomy are more sick than patients with laparoscopic cholecystectomy, and they have a mortality risk within 90 days of admission for cholecystectomy, which is four times that of the general population. Further efforts to reduce surgical trauma in open biliary surgery are motivated.

Objective: To determine the incidence of intraoperative anesthesia-related complications of laparoscopic cholecystectomy. Results: One hundred patients with male to female ratio of 1:8.09 in the age range of 20-80 years (mean 39 years) underwent general anesthesia for laparoscopic cholecystectomy. The duration of operation in 94 laparoscopic cholecystectomy was from 20 to 80 minutes (mean 60.63 minutes). The incidence of intraoperative hypotension was 9%. Four percent of the patients developed arrhythmias. Increase in end-tidal-carbon dioxide (ETCO/sub 2/) was observed in 3% of cases. Conversion rate to open cholecystectomy was 6%. Damage to intraabdominal vessels with trocar insertion occurred in 1% of cases. Conclusion: Although laparoscopic cholecystectomy has major surgical and anesthetic advantages, there are anesthesia related complications requiring specific anesthetic interventions to improve patients outcome without compromising their safety.

Full Text Available Objectives: The most common indication for abdominal surgery in elderly (65 & older is gallstone disease.The elderly are more prone to complication of such surgery due to their other co-morbidity and thus they may benefit mostly from a safer method of surgical procedure. The purpose of this study was to evaluate the safety and outcome of laparoscopic cholecystectomy in elderly compare to the conventional method. Methods & Materials: Via prospective study from June 2005 to March 2008 included all patient older than 60 years of age who underwent cholecystectomy by open (Group A and laparoscopic (Group B method in Milad Hospital.The demographic data (sex age, American Society of Anesthesiologists’ (ASA score, postoperative mortality morbidity, length of stay and operative time were recorded for each patient and were compared between two methods. Data of patient’s analysis by SPSS with chi-square and t test. Results: The study included 311 elderlies (34% men and 66% women. Hundred fifty-seven patients underwent open cholecystectomy; 154 patients underwent laparoscopic cholecystectomy. The mean age was 7141 years. The outcome in group B (laparoscopic included: morality 0%, morbidity 2%, postoperative hospital stay 1 days, mean operation time was 40 minutes. In group A(open: mortality and morbidity rate were 21% and 12% respectively with postoperative hospital stay 331 days and similar operation time as group A. Conclusion: Laparoscopic cholecystectomy is the gold standard treatment and safe procedure in elderly patient and aging is not considered to be a contraindication laparoscopic surgery in such patients.

Laparoscopic cholecystectomy is the gold standard treatment for gallbladder stones. Complications due to laparoscopic procedure are rare, but rate of wound infection in some studies is about 8 %. From January 2007 to December 2008, 320 laparoscopic cholecystectomies were performed at our hospital, and in 4.7 % of them, wound infection of the umbilical trocar was identified. We believe that this infection rate could be lower and that it is necessary to implement a new technique to reduce the wound infection. The aim of the study was to evaluate the benefits of bag extraction of gallbladder to prevent the wound infection. Two-arm, parallel, 1:1, randomised controlled trial (ISRCTN38095251). All patients suffering from symptomatic gallbladder stones of low risk were enrolled for this study and were divided into two groups in basics gallbladder extraction: with (80 patients) or, as usually, without bag (76 patients). All patients with cholecystitis or accidental gallbladder perforation were excluded. We compared all the results to establish whether meaningful differences were found. The final sample analysed (156 patients) consisted of 121 women and 35 men; there were 80 in the control group and 76 in the study group. There were 15 (9.6 %) diagnosed wound infections, eight cases in the study group and seven in the control group. There were no statistically significant differences. The determinant of wound infection in elective laparoscopic cholecystectomy is not the direct contact of the gallbladder with the wound; therefore, bag extraction is not necessary.

Traditionally, laparoscopic cholecystectomy is performed using two 10-mm ports and two 5-mm ports. Recently, a reduction in the number of ports has been suggested as a modification of the standard technique with a view to decreasing pain and improving cosmesis. The safety and effectiveness of using fewer-than-four ports has not yet been established. To assess the benefits (such as improvement in cosmesis and earlier return to activity) and harms (such as increased complications) of using fewer-than-four ports (fewer-than-four-ports laparoscopic cholecystectomy) versus four ports in people undergoing laparoscopic cholecystectomy for any reason (symptomatic gallstones, acalculous cholecystitis, gallbladder polyp, or any other condition). We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 8, 2013), MEDLINE, EMBASE, Science Citation Index Expanded, and the World Health Organization International Clinical Trials Registry Platform portal to September 2013. We included all randomised clinical trials comparing fewer-than-four ports versus four ports, that is, with standard laparoscopic cholecystectomy that is performed with two ports of at least 10-mm incision and two ports of at least 5-mm incision. Two review authors independently identified the trials and extracted the data. We analysed the data using both the fixed-effect and the random-effects models. For each outcome, we calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) based on intention-to-treat analysis, whenever possible. We found nine trials with 855 participants that randomised participants to fewer-than-four-ports laparoscopic cholecystectomy (n = 427) versus four-port laparoscopic cholecystectomy (n = 428). Most trials included low anaesthetic risk participants undergoing elective laparoscopic cholecystectomy. Seven of the nine trials used a single port laparoscopic cholecystectomy and the remaining two trials used three-port laparoscopic

Objective: To assess the role of Intraperitoneal infiltration of Ropivacaine for post-op analgesia in open cholecystectomy in a low resource setting. Study Design: Randomized controlled trial. Place and Duration of Study: Study was conducted at department of Anesthesia, Scouts Hospital Chitral, from Jul 2014 to Jun 2016. Material and Methods: After taking approval from hospital ethical committee, total 126 patients were divided randomly in two groups. Group I (study group) was given intraperitoneal ropivacaine and group II (control group) was given routine standard analgesia. After complete recovery, pain was measure on VAS score (1-10) at 1 hour, 6 hour and 24 hour in all patients. Patients having pain score of 4 or more were managed with nalbuphine 5 mg IV bolus. Data was analyzed by SPSS version 16. Results: The comparison of pain score (after 1, 6and 24 hours of surgery), showed that study group had significantly (p-value<0.05) less mean pain score as compared with placebo group. Significant rate of nausea/vomiting was observed (p-value<0.05) higher (62%) in placebo group as compared with (38%) in study group. Statistically there was no significant difference (p-value>0.05) between groups on the basis of mean age (47.89 ± 8.56 vs. 48.75 ± 9.36), gender (Females 70% vs. 68%), duration of the surgery (88.54 ± 12.34 minutes vs. 91.70 ± 13.50 minutes) and American society of anesthesiologist (ASA) grades in study and placebo group patients respectively. Conclusion: Intraperitoneal ropivacaine infiltration helped in reducing the post op pain significantly in open cholecystectomy. (author)

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. 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. 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). 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.

Full Text Available BACKGROUND: Laparoscopic cholecystectomy has become the gold standard in the treatment of symptomatic cholelithiasis. Some patients require conversion to open surgery and several preoperative variables have been identified as risk factors that are helpful in predicting the probability of conversion. However, there is a need to devise a risk-scoring system based on the identified risk factors to (a predict the risk of conversion preoperatively for selected patients, (b prepare the patient psychologically, (c arrange operating schedules accordingly, and (d minimize the procedure-related cost and help overcome financial constraints, which is a significant problem in developing countries. AIM: This study was aimed to evaluate preoperative risk factors for conversion from laparoscopic to open cholecystectomy in our setting. SETTINGS AND DESIGNS: A case control study of patients who underwent laparoscopic surgery from January 1997 to December 2001 was conducted at the Aga Khan University Hospital, Karachi, Pakistan. MATERIALS AND METHODS: All those patients who were converted to open surgery (n = 73 were enrolled as cases. Two controls who had successful laparoscopic surgery (n = 146 were matched with each case for operating surgeon and closest date of surgery. STATISTICAL ANALYSIS USED: Descriptive statistics were computed and, univariate and multivariate analysis was done through multiple logistic regression. RESULTS: The final multivariate model identified two risk factors for conversion: ultrasonographic signs of inflammation (adjusted odds ratio [aOR] = 8.5; 95% confidence interval [CI]: 3.3, 21.9 and age > 60 years (aOR = 8.1; 95% CI: 2.9, 22.2 after adjusting for physical signs, alkaline phosphatase and BMI levels. CONCLUSION: Preoperative risk factors evaluated by the present study confirm the likelihood of conversion. Recognition of these factors is important for understanding the characteristics of patients at a higher risk of conversion.

Laparoscopic cholecystectomy is considered to be gold standard treatment for symptomatic gall stones. Despite several benefits there are still disadvantages of laparoscopic cholecystectomy in difficult cases where anatomy is disturbed even in experienced hand. Aim of this study is to identify advantages of early conversion to open cholecystectomy in difficult cases and how it should not be associated with surgeon's failure. Methods: Observational study was conducted at tertiary care hospital of Karachi, Pakistan from January 2012 till June 2015. All patients who presented to general surgery department with symptomatic gall stones and planned for laparoscopic cholecystectomy was included in the study. Demographic data was collected. Preoperative workup includes baselines investigations with liver profile test and imaging study (ultrasound scan). All patient underwent laparoscopic cholecystectomy at first. Operative difficulties, incidence of conversion, reason for conversion and complication intra-operative or postoperative were recorded. Data was analyzed using SPSS 20. Results: Out of 1026 patients, 78.26 percent (803) were female. Mean age of patients were 41.30+-8.43 years (range 26-68 years). Common presenting symptoms were pain at upper abdomen and dyspepsia. Most of the patients had multiple gall stones (93.85 percent). Nine hundred and ninety-two patients (96.68 percent) of patients underwent successful laparoscopic cholecystectomy. This includes patients in whom dissections were difficult because of disturbed anatomy of calots triangle. Only 3.13 percent of patients were converted to open cholecystectomy. There was a significant difference (<0.05) in complications observed between completed and converted cholecystectomies. Conclusion: Conversion from laparoscopic to open procedure should be done in cases of technically difficult situations to avoid significant mortality and morbidity. Surgeons experience had a pivotal role in determining its need and

Full Text Available Background and objectives:Laparoscopic cholecystectomy (LC has virtually replaced conventional open cholecystectomy (OC as the standard procedure of treatment for cholelithiasis and cholecystitis. However, OC sometimes becomes a necessity considering the feasibility and safety of the surgical procedure. But the factors that demand conversion from LC to OC differ widely. The present study aimed to determine the prevalence of conversion from LC to OC and to assess the causes of conversion and risk factors related to conversion. Methods: The study was conducted in a referral hospital – ‘Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorder (BIRDEM’ from September 2014 to September 2016. Cases of cholelithiasis with or without cholecystitis, and other gall bladder pathology were included in the study. A team of experienced surgeon performed LC of all selected cases. The causes of conversion to OC were systematically recorded by the surgical team and the risk factors (age, sex, obesity, history of previous abdominal surgery, gallbladder thickness related to conversion from LC to OC was investigated. Results: A total of 261 (M / F = 87 /174 patients were considered eligible for the study. The mean age of all patients was 43 (±1.75 years. For the male and female groups the mean ages were 44±1.9 and 42±1.6 years respectively. Of the total 261 cases, 210 (80.5% patients had cholelithiasis with chronic cholecystitis, 47 (18.0% had gallbladder stone plus acute cholecystitis and 4 (1.5% had gallbladder polyp. Open conversion was required in case of 19 patients. Thus, overall conversion rate was 7.3%. The common causes of conversion were a difficulty in defining Calot’s triangle (42.1%, b injury to cystic artery (21.1% and c injury to bile duct (15.8%. Both male and female had equal risk for conversion. The investigated risk factors like history of previous abdominal surgery, preoperative ERCP, acute

To determine if preoperative clinical, laboratory and radiology data can predict conversion of laparascopic cholecystectomy for acute cholecystitis to open procedure. Retrospective analysis of 44 laparascopic cholecystectomies were performed for acute cholecystitisbetween August 2000 and July 2002 at King Khalid University Hospital, Riyadh, kingdom of Saudi Arabia. Data related to age and sex of patients, maximum body temprature,white blood cell count, gallbladder wall thickness or ultrasonography and timing of surgery from onset of symptoms were collected.The procedure was converted from laparascopic to open cholecystectomy in 10 patients (23%). Conversion rate was significantly high (33% versus zero; p=0.01) if the gallbladder wall was thickened. Conversion rate was significantly low ( Zero versus 32%: p=0.01) if the procedure was performed within 48 hours from the onset of the symptoms. The data relawted to age, sex, white blood cell count and body temprature did not reliably predict conversion of laparascopic cholecystectomy (LD) for acute cholecystitis to open procedure. There was no mortality or major morbidity. Laparascopic cholecystectomy is a safe modality of treatment for acute cholecystitis. Factors associated with increased conversion rate are thickened gallbladder wall on ultrasonographyand delay in surgery for more than 48 hours from the onset of symptoms. (author)

Full Text Available 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 (P1 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.

[Bile duct lesions in laparoscopic cholecystectomy].

Siewert, J R; Ungeheuer, A; Feussner, H

1994-09-01

Laparoscopic cholecystectomy is both resulting in a slightly higher incidence of biliary lesions and a change of prevalence of the type of lesions. Damage to the biliary system occurs in 4 different types: The most severe case is the lesion with a structural defect of the hepatic or common bile duct with (IVa) or without (IVb) vascular injury. Tangential lesions without structural loss of the duct should be denominated as type III (IIIa with additional lesion to the vessels, type IIIb without). Type II comprehends late strictures without obvious intraoperative trauma to the duct. Type I includes immediate biliary fistulae of usually good prognosis. The increasing prevalence of structural defects of the bile ducts appears to be a peculiarity of laparoscopic cholecystectomy necessitating highly demanding operative repair. In the majority of cases, hepatico-jejunostomy or even intraparenchymatous anastomoses are required. Adaptation of well proven principles of open surgery is the best prevention of biliary lesions in laparoscopic cholecystectomy as well as the readiness to convert early to the open procedure.

PRINCIPLES OF SAFETY IN LAPAROSCOPIC CHOLECYSTECTOMY

Full Text Available Background. After more than decade of routine use of laparoscopic cholecystectomy for treatment of symptomatic gallbladder stones, the incidence of biliary injuries, which are potentially life threatening and cause prolonged hospitalization and major morbidity, seems to be increased in laparoscopic cholecystectomy compared with open operation. Injury rate was from some reports 2.5 to 4 times higher than with open operation. There are many proposed classifications of types of biliary injuries.The most frequent direct causes of laparoscopic biliary injury are misidentification of the common bile duct, cautery injuries to the bile duct and improper application of clips to the cystic duct.Conclusions. To avoid misidentification of ducts one should conclusively identify cystic duct and artery, the structures to be divide, in every laparoscopic cholecystectomy. To achieve that goal, Calot’s triangle must be dissected free of fat and fibrous – tissue and the lower end of the gallbladder must be dissected of the liver bed. The only two structures entering the gallbladder should be visible – cystic duct and artery. With avoidance of blind application of cautery and clips to control bleeding one should avoid injury of bile duct. Low cautery settings should be used in portal dissections to prevent arc.With meticulous care in dissection and conclusive identification of cystic duct and artery we can prevent injuries of bile duct, which still have impermissible high incidence. In the article 504 laparoscopic cholecystectomies performed at the Department of abdominal surgery in BPD in 2002 were analysed. We follow priciples of safety in laparoscopic cholecystectomy. There were no biliary injuries reports.

A comparison of the efficacy and safety of the Laryngeal Mask Airway (LMA) Supreme (LMAS) versus the LMA Proseal (LMAP) in elective laparoscopic cholecystectomy. To compare the LMAS with LMAP in terms of ventilatory efficacy, airway leak pressure (airway protection), ease-of-use and complications. Prospective, single-blind, randomised, controlled study. The Hospital del Sureste and Hospital Ramon y Cajal, Madrid, between May 2009 and March 2011. The Hospital del Sureste is a secondary hospital and Hospital Ramon y Cajal is a tertiary hospital. Patients undergoing elective laparoscopic cholecystectomy were studied following informed consent. Inclusion criteria were American Society of Anesthesiologists physical status I to III and age 18 or more. Exclusion criteria were BMI more than 40 kg m, symptomatic hiatus hernia or severe gastro-oesophageal reflux. Anaesthesiologists experienced in the use of LMAP and LMAS participated in the trial. One hundred twenty-two patients were randomly allocated to LMAS or LMAP. Our primary outcome measure was the oropharyngeal leak pressure (OLP). Secondary outcomes were the time and number of attempts for insertion, ease of insertion of the drain tube, adequacy of ventilation and the incidence of complication. Patients were interviewed postoperatively to evaluate the presence of sore throat, dysphagia or dysphonia. Two patients were excluded when surgery changed from laparoscopic to open. A total of 120 patients were finally included in the analysis. The mean OLP in the LMAP group was significantly higher than that in the LMAS group (30.7 ± 6.2 versus 26.8 ± 4.1 cmH2O;P drain tube, complications and postoperative pharyngolaryngeal adverse events were similar in both groups. The LMAP has a higher OLP and achieves a higher maximum tidal volume compared to the LMAS, in patients undergoing elective laparoscopic cholecystectomy. The success of the first attempt insertion was higher for the LMAS.

Full Text Available Background. Day-case laparoscopic cholecystectomy (LC is a safe and cost-effective treatment for gallstones. In 2006, our institution recorded an 86% laparoscopic, 10% day-case, and 5% readmission rate. A gallbladder pathway was therefore introduced in 2007 with the aim of increasing daycase rates. Methods. Patients with symptomatic gallstones, proven on ultrasound, were referred to a specialist-led clinic. Those suitable for surgery were consented, preassessed, and provided with a choice of dates. All defaulted to day case unless deemed unsuitable due to comorbidity or social factors. Results. The number of cholecystectomies increased from 464 in 2006 to 578 in 2008. Day-case rates in 2006, 2007, 2008, and June 2009 were 10%, 20%, 30%, and 61%, respectively. Laparoscopic and readmission rates remained unchanged. Conversion rates for elective cholecystectomy fell from 6% in 2006 to 3% in 2009. Conclusions. Development of a gallbladder pathway increased day-case rates sixfold without an associated increase in conversion or readmission rates.

Improved laparoscopic experience and techniques have made laparoscopic cholecystectomy (LC) feasible options in cirrhotic patients. This study was designed to compare the risk and benefits of open cholecystectomy (OC) versus LC in compensated cirrhosis. A randomized prospective study, in the period from October 2002 till December 2006, where 110 cirrhotic patients with symptomatic gallstone were randomly divided into OC group (55 patients) and LC group (55 patients). There was no operative mortality. In LC group 4 (7.33%) patients were converted to OC. Mean surgical time was significantly longer in OC group than LC group (96.13+17.35 min versus 76.13+15.12) P<0.05, associated with significantly higher intraoperative bleeding in OC group (P<0.01), necessitating blood transfusions to 7 (12.72%) patients in OC group. The time to resume diet was 18.36+8.18 h in LC group which is significantly earlier than in OC group 47.84+14.6h P<0.005. Hospital stay was significantly longer in OC group than LC group (6+1.74 days versus 1.87+1.11 days) P<0.01 with low postoperative morbidity. LC in cirrhotics is still complicated and highly difficult which associates with significant morbidity compared with that of patients without cirrhosis. However, it offers lower morbidity, shorter operative time; early resume dieting with less need for blood transfusion and reducing hospital stay than OC.

Place and Duration of Study: Surgical department Military Hospital from Jul 2011-Dec 2013. Material and Methods: A total of 1020 patients who underwent laparoscopic cholecystectomy for acute or chronic cholecystitis and gallstone pancreatitis were included in our study while those who had previously undergone abdominal surgeries, those with high risk for general anesthesia, immunocompromised patients, with age greater than 70 years and having comorbidities like cardiac insufficiency, severe asthma, chronic liver disease with ascites and compromised renal functions were excluded from the study. Patients demographic data, operative time, intra-operative findings, intra-operative difficulties, post-operative complications, conversion rate to open cholecystectomy and post-operative recovery time were recorded. Data was analyzed by using SPSS version 21. Results: Out of 1020 patients 907 were females while 113 were males with male to female ratio of 1:8.02. Age range was 20-70 with mean age of 50 ± 10.456 years. 44.7% patients presented with the clinical features of acute cholecystitis, 540 (52.94%) with chronic cholecystitis and 23 (2.28%) with acute pancreatitis. Mean operative time was 20 minutes in asymptomatic patients, while 40 minutes in acute cholecystitis and 35 minutes in chronic gallstone disease. Gall bladder perforation, bleeding from cystic artery and bile spillage were mostly encountered per-operative difficulties. Only 37 (3.6%) patients were converted to open cholecystectomy. Post-operative complications occur in only 122 (12%) patients. 938 (92%) patients were discharged within 48 hours. of surgery.

Surgeons are still following the old habit of routine subhepatic drainage following laparoscopic cholecystectomy (LC). This study aims to compare the outcome of subhepatic drainage with no drainage after LC. This prospective study was conducted in two phases. Phase I was open, randomized controlled trial (RCT), conducted in Civil Hospital Karachi, from August 2004 to June 2005. Phase II was descriptive case series, conducted in author's practice hospitals of Karachi, from July 2005 to December 2009. In phase I, 170 patients with chronic calculous cholecystitis underwent LC. Patients were divided into two groups, subhepatic drainage (group A: 79 patients) or no drainage (group B: 76 patients). The rest 15 patients were excluded either due to conversion or elective subhepatic drainage. In phase II, 218 consecutive patients were enrolled, who underwent LC with no subhepatic drainage. Duration of operation, character, and amount of drain fluid (if placed), postoperative ultrasound for subhepatic collection, postoperative chest X-ray for the measurement of subdiaphragmatic air, postoperative pain, postoperative nausea/vomiting, duration of hospital stay, and preoperative or postoperative complications were noted and analyzed. Duration of operation and hospital stay was slightly longer in group A patients (P values 0.002 and 0.029, respectively); postoperative pain perception, nausea/vomiting, and postoperative complications were nearly same in both groups (P value 0.064, 0.078, and 0.003, respectively). Subhepatic fluid collection was more in group A (P = 0.002), whereas subdiaphragmatic air collection was more in group B (P = 0.003). Phase II results were nearly similar to group B patients in phase I. Routine subhepatic drainage after LC is not necessary in uncomplicated cases.

In this article, we report the current surgical approach to gallbladder disease at a major referral hospital in rural Guatemala. Complications in a cohort of patients undergoing open versus laparoscopic cholecystectomy were catalogued. We reviewed cholecystectomies performed by surgeons at the Hospital Nacional de San Benito in El Peten, Guatemala, after the adoption of the laparoscopic approach. Laparoscopic cholecystectomies (LCs) between 2014 and 2015 (n = 42) were reviewed and matched by 58 randomly selected open cholecystectomies (OCs) during the same period. Patient demographics were similar in the LC and OC groups. Of the 63 patients who had elective surgery, 43 (68%) underwent OC. Conversion rate, hospital length of stay, and readmission rate were 4%, 4.8 days, and 5%, respectively. Complications were similar between groups. Despite the low number of LCs, their complications were not different from that of OCs. During the study period, a large number of cholecystectomies continued to be open, even in the elective setting. Published by Elsevier Inc.

To determine if dogs that undergo laparotomy for cholecystectomy suffer from a greater number or magnitude of perianesthetic complications, including hypotension, hypothermia, longer recovery time, and lower survival rate, than dogs that undergo laparotomy for hepatic surgery without cholecystectomy. Retrospective cohort study. One hundred and three dogs, anesthetised between January 2007 and October 2011. The variables collected from the medical record included age, weight, gender, surgical procedure, pre-operative bloodwork, American Society of Anesthesiologists (ASA) status, emergency status, total bilirubin concentration, anesthetic agents administered, body temperature nadir, final body temperature, hypotension, duration of hypotension, blood pressure nadir, intraoperative drugs, anesthesia duration, surgery duration, time to extubation, final diagnosis, days spent in the intensive care unit (ICU), total bill, survival to discharge, and survival to follow-up. No significant difference in body temperature nadir, final temperature, presence of hypotension, duration of hypotension, blood pressure nadir, the use of inotropes, or final outcome was found between dogs undergoing cholecystectomy and dogs undergoing exploratory laparotomy for other hepatic disease. Dogs that had cholecystectomy had longer anesthesia durations and longer surgery durations than dogs that did not have cholecystectomy. No significant differences existed for temperature nadir (34.8 versus 35.3°C; non-cholecystectomy versus cholecystectomy), final temperature (35.6 versus 35.9°C), time to extubation (30 versus 49 minutes), duration of hypotension (27 versus 21 minutes), or MAP nadir (56 versus 55 mmHg). Hypotension occurred in 66% and 74% and inotropes were used in 64% and 53%, for non-cholecystectomy and cholecystectomy patients, respectively. Dogs that underwent cholecystectomies did not suffer a greater number of anesthesia complications than did dogs undergoing hepatic surgery without

Valid and user-friendly prediction models for conversion to open cholecystectomy allow for proper planning prior to surgery. The Cairns Prediction Model (CPM) has been in use clinically in the original study site for the past three years, but has not been tested at other sites. A retrospective, single-centred study collected ultrasonic measurements and clinical variables alongside with conversion status from consecutive patients who underwent laparoscopic cholecystectomy from 2013 to 2016 in The Townsville Hospital, North Queensland, Australia. An area under the curve (AUC) was calculated to externally validate of the CPM. Conversion was necessary in 43 (4.2%) out of 1035 patients. External validation showed an area under the curve of 0.87 (95% CI 0.82-0.93, p = 1.1 × 10 -14 ). In comparison with most previously published models, which have an AUC of approximately 0.80 or less, the CPM has the highest AUC of all published prediction models both for internal and external validation.

Analgesic effect of bilateral subcostal tap block after laparoscopic cholecystectomy

International Nuclear Information System (INIS)

Karam, K.; Khan, B.I.

2018-01-01

Pain after laparoscopic cholecystectomy is mild to moderate in intensity. Several modalities are employed for achieving safe and effective postoperative analgesia, the benefits of which adds to the early recovery of the patients. As a part of multimodal analgesia, various approaches of Transversus abdominis plane (TAP) block has been used for management of parietal and incisional components of pain after laparoscopic cholecystectomy. This study was designed to compare the analgesic efficacy of two different approaches of ultrasound guided TAP block, i.e., Subcostal-TAP block technique with ultrasound guided Posterior-TAP block for post-operative pain management in patients undergoing laparoscopic cholecystectomy under general anaesthesia. Methods: In this double blinded randomized controlled study, consecutive nonprobability sampling was done and a total of 126 patients admitted for elective laparoscopic cholecystectomy fulfilling the inclusion criteria were selected. After induction of general anaesthesia, patients were randomized through draw method and received either ultrasound guided posterior TAP block with 0.375% bupivacaine (20ml volume) on each side of the abdomen or subcostal TAP block bilaterally with the same. Up to 24 hours postoperatively, static and dynamic numeric rating pain scores were assessed. Results: We found statistically significant difference in mean static pain scores over 24 hours postoperatively in subcostal TAP group, suggesting improved analgesia. However, mean dynamic postoperative pain scores were comparable between the two groups. Whereas, patients in both groups were satisfied with pain management. Conclusions: Ultrasound guided subcostal TAP block provides better postoperative analgesia as compared to the Posterior TAP block in laparoscopic cholecystectomy. Otherwise both of the approaches improve patient outcomes towards early recovery and discharge from hospital. (author)

Full Text Available BACKGROUND Postoperative pain after open cholecystectomy is associated with respiratory dysfunction, increased stress response and prolonged hospital stay. We compare intravenous paracetamol (7.5 mg/kg plus intercostal nerve block with local anaesthetic ropivacaine 0.5% to intravenous paracetamol (15 mg/kg on pain control after open cholecystectomy. MATERIALS AND METHODS 140 patients, who underwent for open cholecystectomy, were randomly divided into two groups of 70. The patients were randomly allocated to any of the following two groups depending upon the drug used for analgesia (Group P or Group I Intravenous paracetamol 15 mg/kg was given to patients of group P and paracetamol 7.5 mg/kg with Intercostal nerve block in right side 6-10 intercostal nerves with 2 ml local anaesthetic ropivacaine 0.5% in each space was given to patients of group I just after intubation before incision. When the patients were transferred to postoperative recovery room, intensity of pain was recorded by response from the patients using 100 mm linear visual analogue scale ranging from 0 to 100. The pain scoring was done in the immediate postoperative period (when the patient was able to communicate in the post anaesthesia care unit, at 30 minutes, 1 hr. then hourly up to 24 hrs. till patient complained of pain with VAS score 40 or more. RESULTS The severity of pain in VAS score was lower in immediate postoperative period, at 30 minutes, 1 hour and 2 hours postoperatively in group I than the group P and those were statistically significant (p<0.001.

Endoscopic retrograde cholangiopancreatography followed by laparoscopic cholecystectomy is often used as definitive treatment for common bile duct stones. The aim of this study was to investigate the optimal time interval between endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. PubMed and Embase were searched for studies comparing different time delays between endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. Observational studies and randomized controlled trials were included. Primary outcome was conversion rate from laparoscopic to open cholecystectomy and secondary outcomes were complications, mortality, operating time, and length of stay. A total of 14 studies with a total of 1930 patients were included. The pooled estimate revealed an increase from a 4.2% conversion rate when laparoscopic cholecystectomy was performed within 24 h of endoscopic retrograde cholangiopancreatography to 7.6% for 24-72 h delay to 12.3% when performed within 2 weeks, to 12.3% for 2-6 weeks, and to a 14% conversion rate when operation was delayed more than 6 weeks. According to this systematic review, it is preferable to perform cholecystectomy within 24 h of endoscopic retrograde cholangiopancreatography to reduce conversion rate. Early laparoscopic cholecystectomy does not increase mortality, perioperative complications, or length of stay and on the contrary it reduces the risk of reoccurrence and progression of disease in the delay between endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy.

The benefits of laparoscopic cholecystectomy, including rapid recovery and fewer infections, have been largely unavailable to the majority of people in developing countries. Compared to other countries, Mongolia has an extremely high incidence of gallbladder disease. In 2005, only 2% of cholecystectomies were performed laparoscopically. This is a retrospective review of the transition from open to laparoscopic cholecystectomy throughout Mongolia. A cross-sectional, retrospective review was conducted of demographic patient data, diagnosis type, and operation performed (laparoscopic versus open cholecystectomy) from 2005-2013. Trends were analyzed from 6 of the 21 provinces (aimags) throughout Mongolia, and data were culled from 7 regional diagnostic referral and treatment centers and 2 tertiary academic medical centers. The data were analyzed by individual training center and by year before being compared between rural and urban centers. We analyzed and compared 14,522 cholecystectomies (n = 4,086 [28%] men, n = 10,436 [72%] women). Men and women were similar in age (men 52.2, standard deviation 14.8; women 49.4, standard deviation 15.7) and in the percentage undergoing laparoscopic cholecystectomy (men 39%, women 42%). By 2013, 58% of gallbladders were removed laparoscopically countrywide compared with only 2% in 2005. In 2011, laparoscopic cholecystectomy surpassed open cholecystectomy as the primary method for gallbladder removal countrywide. More than 315 Mongolian health care practitioners received laparoscopic training in 19 of the country's 21 aimags (states). By 2013, 58% of cholecystectomies countrywide were performed laparoscopically, a dramatic increase over 9 years. The expansion of laparoscopic cholecystectomy has transformed the care of biliary tract disease in Mongolia despite the country's limited resources. Copyright © 2016 Elsevier Inc.

Objectives: To evaluate the results of 160 consecutive laparoscopic cholecystectomy using sectorisation based port site selection to improve ergonomics for surgeons. Design: Descriptive study. Place and Duration of study: PNS Shifa Karachi, Pakistan from Feb 2011 to Feb 2012. Patients and Methods: In this prospective study, 160 consecutive patients had undergone laparoscopic cholecystectomy in a tertiary care hospital using sectorisation for trocar placement. All patients with symptomatic gallstones, acute calculous cholecystitis and empyema gallbladder were included. Patients with choledocholithiasis were excluded from the study. The collected data included age, sex, diagnosis, history of previous surgery, conversion to open surgery and its reasons, operative time, post-operative hospital stay, complications and laparoscopy related complications to the surgeon such as shoulder pain, wrist stress and pain, finger joint pain and stress exhaustion. Result: One hundred and sixty patients underwent laparoscopic cholecystectomy with mean age 45 +- 12.9 years. Female to male ratio was 7.8:1. A total of 110 patients had chronic cholecystitis / biliary colic, 34 patients were with acute cholecystitis and 16 patients had diagnosis of empyema gallbladder. The mean operative time was 35.3+-14.6 min. Conversion rate to open surgery was 1.2%. Complications included bleeding from cystic artery (n=1) and injury to common hepatic duct (CHD) (n=1). One patient developed port site hernia post operatively. There was no incidence of laparoscopy related complications in surgeon such as pain shoulder, strains on the wrist joint, stress exhaustion and hand-finger joint pain. Conclusion: Sectorisation technique can be used in laparoscopic cholecystectomy in order to avoid the physical constraints of laparoscopic shoulder, hand finger joint pain, tenosynovitis, stress exhaustion, and hand muscle injury without increasing any morbidity to the patients.

Full Text Available Irene Sellbrant,1 Gustaf Ledin,2 Jan G Jakobsson2 1Department of Anaesthesia, Capio Lundby, Gothenburg, 2Department of Anaesthesia and Intensive Care, Institution for Clinical Science, Karolinska Institutet, Danderyds Hospital, Stockholm, Sweden Abstract: Laparoscopic cholecystectomy is one of the most common general surgical procedures. The aim of the present paper is to review current evidence and well-established practice for elective laparoscopic perioperative management. There is no firm evidence for best anesthetic technique, further high quality studies assessing short as well as more protracted outcomes are needed. Preventive multi-modal analgesia, combining non-opioid analgesics, paracetamol, nonsteroidal anti-inflammatory drugs or coxib, and local anesthesia, has a long history. Local anesthesia improves postoperative pain and facilitates discharge on the day of surgery. Whether transversus abdominis plane-block has clinically important advantages compared to local infiltration analgesia needs further studies. Single intravenous dose steroid, dexamethasone, reduces postoperative nausea and vomiting, pain, and enhances the recovery process. Multi-modal analgesia is reassuringly safe thus having a positive benefit versus risk profile. Adherence to modern guidelines avoiding prolonged fasting and liberal intravenous fluid regime supports rapid recovery. The effects of CO2 insufflation must be acknowledged and low intra-abdominal pressure should be sought in order to reduce negative cardiovascular/respiratory effects. There is no firm evidence supporting heating and humidification of the insufflated gas. The potential risk for CO2/gas entrainment into vasaculture, gas emboli, or subcutaneous/intra-thoracic into the pleural space must be kept in mind. Laparoscopic cholecystectomy in ASA 1-2 patients following a multi-modal enhanced recovery protocol promotes high success rate for discharge on the day of surgery. Keywords: laparoscopic

Full Text Available JCMSBackground and Objectives: Tracheostomy is electively performed in critically ill patients requiring prolonged respiratory support. The risk of transporting, the increasing associated cost and operative room schedule are some of the obstacles for wider acceptance of this procedure. The use of rigid selection criteria exclude many patients who would benefit of this approach. The present study was designed to determine the safety of open bedside tracheostomy (OBT as a routine intensive care units (ICU procedure without any selection criteria, considering its peri and postoperative complications.Materials & Methods: Retrospective medical chart review of all patients that underwent elective tracheostomy between June 2014 and January 2015.Results: The study group comprised 52 patients with a mean age of 40.4±15.1 years. The incidence of intra-procedure complications was 5.7% and post-procedure complications was 3.8%.Conclusions: Open bedside tracheostomy seems to be a safe and simple procedure, even when performed by a trained resident under controlled circumstances, and should be considered as an option for ICU patients.JCMS Nepal. 2015;11(1: 9-11

Yousef, Gamal T; Lasheen, Ahmed E

2012-01-01

Laparoscopic cholecystectomy became the standard surgery for gallstone disease because of causing less postoperative pain, respiratory compromise and early ambulation. This study was designed to compare spinal anesthesia, (segmental thoracic or conventional lumbar) vs the gold standard general anesthesia as three anesthetic techniques for healthy patients scheduled for elective laparoscopic cholecystectomy, evaluating intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction. A total of 90 patients undergoing elective laparoscopic cholecystectomy, between January 2010 and May 2011, were randomized into three equal groups to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under segmental thoracic (TSA group) or conventional lumbar (LSA group) spinal anesthesia or general anesthesia (GA group). To achieve a T3 sensory level we used (hyperbaric bupivacaine 15 mg, and fentanyl 25 mg at L2/L3) for LSAgroup, and (hyperbaric bupivacaine 7.5 mg, and fentanyl 25 mg at T10/T11) for TSAgroup. Propofol, fentanyl, atracurium, sevoflurane, and tracheal intubation were used for GA group. Intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction were compared between the three groups. All procedures were completed laparoscopically by the allocated method of anesthesia with no anesthetic conversions. The time for the blockade to reach T3 level, intraoperative hypotensive and bradycardic events and vasopressor use were significantly lower in (TSA group) than in (LSA group). Postoperative pain scores as assessed throughout any time, postoperative right shoulder pain and hospital stay was lower for both (TSA group) and (LSA group) compared with (GA group). The higher degree of patients satisfaction scores were recorded in patients under segmental TSA. The present study not only confirmed that both segmental TSA and conventional

Objectives: To identify pre-operative factors that predisposes to conversion of laparoscopic cholecystectomy. Methodology: Patients with symptomatic cholelithiasis from a tertiary hospital were selected for this cross-sectional study. The patient data was obtained from the hospital online database. Patients aged ?18 years with clinical diagnosis of symptomatic cholelithiasis who underwent laparoscopic cholecystectomy from January 2013 to December 2014 were included in the study. Those who underwent planned open cholecystectomy, patients with gallbladder polyps, acalculous cholecystitis and history of previous laparotomy were excluded from the study. Data were analyzed using chi-square test, Fisher's exact test and logistic regression. Results: Two hundred patients fulfilled the inclusion criteria. Conversion to open cholecystectomy was seen in 28 patients (14%). Patients with acute cholecystitis were 3.4 times more likely and males were 2.5 times more likely to undergo conversion. The likelihood of conversion increased by 0.9 times for each year of increase in age. Patients with diabetes mellitus were 3.8 times more likely to undergo conversion. Hypertension was also a significant factor contributing to a conversion. After a logistic regression analysis, only three factors remained statistically independently significant: diabetes mellitus (95% CI: 0.1 to 0.6), acute cholecystitis (95% CI: 0.1 to 0.7) and male gender (95%CI: 0.7 to 0.9). Conclusions: Decision to convert laparoscopic cholecystectomy to open should be taken earlier in a male patient with diabetes mellitus, acute cholecystitis and advancing age. (author)

The applications of laparoendoscopic single-site (LESS) surgery, including cholecystectomy, are occurring quickly, although little is generally known about issues associated with the learning curve of this new technique including operative time, conversion rates, and safety. We prospectively followed all patients undergoing LESS cholecystectomy, and compared operations undertaken at our institutions in cohorts of 25 patients with respect to operative times, conversion rates, and complications. One-hundred fifty patients of mean age 46 years underwent LESS cholecystectomy. No significant differences in operative times were demonstrable between any of the 25-patient cohorts operated on at our institution. A significant reduction in operative times (p < 0.001) after completion of 75 LESS procedures was, however, identified with the experience of a single surgeon. No significant reduction in the number of procedures requiring an additional trocar(s) or conversion to open operations was observed after completion of 25 LESS cholecystectomies. Complication rates were low, and not significantly different between any 25-patient cohorts. For surgeons proficient with multi-incision laparoscopic cholecystectomy, the learning curve for LESS cholecystectomy begins near proficiency. Operative complications and conversions were infrequent and unchanged across successive 25-patient cohorts, and were similar to those reported for multi-incision laparoscopic cholecystectomy after the learning curve.

Natural orifice transluminal endoscopic surgery (NOTES) is a technique still in experimental development whose safety and effectiveness call for assessment through clinical trials. In this paper we present a three-arm, noninferiority, prospective randomized clinical trial of 1 year duration comparing the vaginal and transumbilical approaches for transluminal endoscopic surgery with the conventional laparoscopic approach for elective cholecystectomy. Sixty female patients between the ages of 18 and 65 years who were eligible for elective cholecystectomy were randomized in a ratio of 1:1:1 to receive hybrid transvaginal NOTES (TV group), hybrid transumbilical NOTES (TU group) or conventional laparoscopy (CL group). The main study variable was parietal complications (wound infection, bleeding, and eventration). The analysis was by intention to treat, and losses were not replaced. Cholecystectomy was successfully performed on 94% of the patients. One patient in the TU group was reconverted to CL owing to difficulty in maneuvering the endoscope. After a minimum follow-up period of 1 year, no differences were noted in the rate of parietal complications. Postoperative pain, length of hospital stay, and time off from work were similar in the three groups. No patient developed dyspareunia. Surgical time was longer among cases in which a flexible endoscope was used (CL, 47.04 min; TV, 64.85 min; TU, 59.80 min). NOTES approaches using the flexible endoscope are not inferior in safety or effectiveness to conventional laparoscopy. The transumbilical approach with flexible endoscope is as effective and safe as the transvaginal approach and is a promising, single-incision approach.

Full text: Introduction: The risk of bile duct injury after laparoscopic cholecystectomy is higher than open cholecystectomy. Objective: To discuss the importance of minimally invasive treatment options in the management of bile duct injuries after laparoscopic cholecystectomy and to present our approach in the management. Materials and methods: Management of 25 patients with symptomatic bile duct injury after laparoscopic cholecystectomy was retrospectively evaluated. Percutaneous collection drainage, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) and percutaneous biliary drainage were performed for the management of the patients. Results: Mean age of the patients (15 women, 10 men) was 55. Either ultrasonography or computed tomography guided percutaneous drainage was performed in 13 patients. 9 of them completely recovered only with percutaneous drainage. In 4 of them ERCP was performed because of high drainage volume. In 9 of the patients with jaundice and high bilirubin levels ERCP was performed as the first option. And 3 patients were reoperated because of acute abdomen signs. ERCP, MRCP and PTC revealed type A in 7, type E2 in 3, type E3 in 3 and type E4 in 1 of the patients according to Strasberg classification. Conclusion: Presenting symptoms of the patients with symptomatic bile duct injury are useful in the determination of the treatment option.

2011-02-01

Full Text Available Abstract Background Surgical site infections are common, so effective antibiotic concentrations at the sites of infection are required. Surgery can lead to physiological changes influencing the pharmacokinetics of antibiotics. The aim of the study is to evaluate contemporary peri-operative prophylactic dosing of cefazolin by determining plasma and subcutaneous interstitial fluid concentrations in patients undergoing elective of semi-elective abdominal aortic aneurysm (AAA open repair surgery. Methods/Design This is an observational pharmacokinetic study of patients undergoing AAA open repair surgery at the Royal Brisbane and Women's Hospital. All patients will be administered 2-g cefazolin by intravenous injection within 30-minutes of the procedure. Participants will have samples from blood and urine, collected at different intervals. Patients will also have a microdialysis catheter inserted into subcutaneous tissue to measure interstitial fluid penetration by cefazolin. Participants will be administered indocyanine green and sodium bromide as well as have cardiac output monitoring performed and tetrapolar bioimpedance to determine physiological changes occurring during surgery. Analysis of samples will be performed using validated liquid chromatography tandem mass-spectrometry. Pharmacokinetic analysis will be performed using non-linear mixed effects modeling to determine individual and population pharmacokinetic parameters and the effect of peri-operative physiological changes on cefazolin disposition. Discussion The study will describe cefazolin levels in plasma and the interstitial fluid of tissues during AAA open repair surgery. The effect of physiological changes to the patient mediated by surgery will also be determined. The results of this study will guide clinicians and pharmacists to effectively dose cefazolin in order to maximize the concentration of antibiotics in the tissues which are the most common site of surgical site infections.

Since 1987 when this procedure began in France and them, became popular all over the world, it isn't any doubt that is the best choice for Cholecystectomy in patients with cholelytiasis. We began our experience in 1996 they have been operated 562 patients by this technique over 1839 cholecystectomy until April 2004, which corresponds to a 31%. We have suffered all the changes in the interpretation and application of law 100, which excludes the procedure from the State Obligatory Health insurance and many Promoting health Enterprises prohibit it's practice, essentially because they ignore the good results it has which are similar to open cholecystectomy. We registered our patients and procedures since the beginning of this experience for evaluation, also to compare it with the medical literacy about it and to verify by ourselves the benefits of minimal invasive surgery

Place and Duration of Study: PNS Shifa Karachi and CMH Lahore, Pakistan from Nov 2009 to Jan 2013. Patients and Methods: A prospective analysis of complications occurring in first 400 consecutive laparoscopic cholecystectomies by a single consultant/unit at a tertiary care hospital was made. Out of total 421 patients presenting with symptomatic gall stone disease in a single unit, 21 cases that underwent open cholecystectomy were excluded from the study. Laparoscopic cholecystectomies were performed using three port and four port technique and data including age, sex, diagnosis, number of trocar placements, conversion to open surgery and its reasons, operative time, post-operative hospital stay and complications was collected on personal computer and analyzed using Statistical package for social sciences (SPSS) version 13. Results: Total 400 patients were included in study with median age of 44 years. Female to male ratio was 5.3: 1. Depending upon the preoperative diagnosis and laparoscopic findings, patients had diagnosis of Chronic cholecystitis / biliary colic 68.25%, acute cholecystitis 23.75%, empyema gall bladder 7.25%, gallstone pancreatitis 0.5% and mucocele gallbladder 0.25%. Median operating time was 30min. Median hospital stay was 1 days (range 1 -20 days). Conversion rate was 1.25%. Postoperative complications included bleeding 0.5%, biliaryperitonitis due to cystic duct leak 0.25%, biloma 0.25%, sub hepaticabscess 0.25%, subcutaneous fat necrosis right flank at drain site 0.25%, umbilical trocarsite infection 2%, keloid at umbilical port site 0.25% and incisional hernia at umbilicus 0.25%. There was one hospital death due to myocardial infarction on 2nd post-operative day. Conclusion: Laparoscopic Cholecystectomy is associated with some serious complications

Skin preparation with antiseptic agents is commonly recommended for incisional site cleansing before surgery. We present the result of a prospective case series submitted to a scheduled pre-operative antiseptic procedure combining chlorhexidine gluconate and povidone-iodine before elective laparoscopic cholecystectomy. Consecutive patients underwent pre-operative standardized cleansing of the operation site combining chlorhexidine gluconate and povidone-iodine. Patients were reviewed one week and four weeks post-operatively. Post-operative infection was observed in seven patients (4.3%). All observed infections were port-site infections, always located at the level of the umbilical incision. In all cases infections involved skin and subcutaneous tissue. Staphylococcus aureus was isolated in five patients (71.4%) and miscellaneous aerobic gram-positive bacteria in two subjects (28.6%). Post-operative hospital stay was the only factor significantly associated with the development of port-site infections. Port-site infections are a common complication after elective laparoscopic cholecystectomy. The proposed pre-operative disinfection procedure is effective in reducing port-site infections. Reducing hospital stay may contribute to limiting the occurrence of this complication.

Full Text Available BACKGROUND: We report the results of our experience on laparoscopic cholecystectomy in sickle cell disease patients in Niger, which is included in the sickle cell belt. METHODS: A prospective study covering a period of 45 months, from July 2004 to March 2008. We included all sickle cell disease patients that underwent laparoscopic cholecystectomy. Blood transfusion was done for patients with haemoglobin (Hb levels less than 9g/dl. Homozygous and composite heterozygous patients were admitted in intensive care unit for 24 hours or plus post operatively. RESULTS:The series included 47 patients operated by the same surgeon, 31 females (66% and 16 males (34% (Ratio: 0.51. The average age was 22.4 years (range: 11 to 46 years and eleven (23.4% of them were aged less than 15 years. The types of sickle cell disease found were 37 SS, 2 SC, 1 S beta-thalassemia and 7 AS. Indications for surgery were biliary colic in 29 cases (61.7% and acute cholecystitis in 18 cases (38.3%. The mean operative time was 64 min (range: 42 to 103 min. Conversion to open cholecystectomy in 2 cases (4.2 % for non recognition of Calot‘s triangle structures. The postoperative complications were: four (4 cases of vaso-occlusive crisis and one case of acute chest syndrome. The mean postoperative hospital stay was 3,5days (range: 1 to 9 days. No mortality was encountered. CONCLUSION: Laparoscopic cholecystectomy is a safe procedure in sickle cell patients. It should be a multidisciplinary approach and involve a haematologist, an anaesthesiologist and a surgeon.

Generally, before being operated on, patients will be given informal information by the healthcare providers involved in the care of the patients (doctors, nurses, ward clerks, or healthcare assistants). This information can also be provided formally in different formats including written information, formal lectures, or audio-visual recorded information. To compare the benefits and harms of formal preoperative patient education for patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2013), MEDLINE, EMBASE, and Science Citation Index Expanded to March 2013. We included only randomised clinical trials irrespective of language and publication status. Two review authors independently extracted the data. We planned to calculate the risk ratio with 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) with 95% CI for continuous outcomes based on intention-to-treat analyses when data were available. A total of 431 participants undergoing elective laparoscopic cholecystectomy were randomised to formal patient education (215 participants) versus standard care (216 participants) in four trials. The patient education included verbal education, multimedia DVD programme, computer-based multimedia programme, and Power Point presentation in the four trials. All the trials were of high risk of bias. One trial including 212 patients reported mortality. There was no mortality in either group in this trial. None of the trials reported surgery-related morbidity, quality of life, proportion of patients discharged as day-procedure laparoscopic cholecystectomy, the length of hospital stay, return to work, or the number of unplanned visits to the doctor. There were insufficient details to calculate the mean difference and 95% CI for the difference in pain scores at 9 to 24 hours (1 trial; 93 patients); and we did not identify clear evidence of

Laparoendoscopic single site (LESS) surgery promises improved cosmesis and possibly less pain. However, given the small series reported to date, true estimates of the advantages and possible disadvantages of LESS surgery remain unknown. This study was undertaken to evaluate the first 100 patients undergoing LESS cholecystectomy at our institution. Patients referred for cholecystectomy since November 2007 were considered for LESS cholecystectomy. Outcomes, including blood loss, operative time, complications, and length of stay, were recorded. Outcomes are compared with an uncontrolled concurrent group of patients undergoing multi-incision laparoscopic (i.e., conventional) cholecystectomy. One hundred patients with a median age of 44 years underwent LESS cholecystectomy; 30 patients with a median age of 46 years underwent conventional cholecystectomy over the same time period. Median operative time (70 vs 66 minutes, P = 0.67, Mann-Whitney) and hospital length of stay (1 vs 1 day, P = 0.81, Mann-Whitney) were not different for patients undergoing LESS or multi-incision cholecystectomies, respectively. Five patients undergoing LESS cholecystectomy had postoperative complications: cystic duct stump leak (one), pain control issues (three), and urinary retention (one). LESS cholecystectomy is a safe and effective alternative to conventional cholecystectomy. It can be undertaken without added operative time and provides patients with minimal, if any, scarring.

Full Text Available United European Gastroenterology provide wide studies and researches on the economic impact of the digestive diseases across the countries that are members of the European Union, very useful in planning health services, in making the case for investment in research where there are clear gaps in knowledge, and in reflecting the economic differences across the EU member states in the funding available to support health services. These studies reflect that there are important disparities in the accessibility to high-quality healthcare even among the industrialized countries. Out of all the digestive diseases, the gallstone disease is one of the most common and expensive of the health problems, in industrialized countries, like those of the European Union are. In general, symptomatic or complicated gallstone disease is treated by cholecystectomy, with surgical removal of the gallbladder. The advent of laparoscopic cholecystectomy has revolutionized the management of the gallstone disease, causing an increase in the rate of cholecystectomies. This study represents an analysis of the hospitalization costs involved by two surgical treatment options: laparoscopic cholecystectomy and open cholecystectomy. The investigation of the costs was done according to the type of intervention chosen and comprised the direct costs of hospitalization, including diagnostic tests and general expenses of medical assistance, pharmaceutical and medical supplies. The results are based on the analysis of the costs of cholecystectomies in the surgical department of the Emergency County Hospital Oradea for the year 2014 (781 cases. The average cost per hospitalized patient was 1.970 RON, lower in patients with laparoscopic cholecystectomy (1.579 RON. The average cost per patient with open cholecystectomy was 55% higher than for laparoscopic surgery (2.442 RON. Even if the laparoscopic operation cost is higher because of the equipment it uses, the reduction of the number of

Recent enthusiasm in the surgical community for less invasive surgical approaches has resulted in widespread application of single-incision techniques. This has been most commonly applied in laparoscopic cholecystectomy in general surgery. Cosmesis appears to be improved, but other advantages remain to be seen. Feasibility has been demonstrated, but there is little description in the current literature regarding complications. We report the case of a patient who previously underwent single-incision laparoscopic cholecystectomy for symptomatic gallstone disease. After a brief symptom-free interval, she developed acute pancreatitis. At evaluation, imaging results of ultrasonography and magnetic resonance cholangiopancreatography demonstrated a retained gallbladder with cholelithiasis. The patient was subsequently referred to our hospital, where she underwent further evaluation and surgical intervention. Our patient underwent 4-port laparoscopic remnant cholecystectomy with transcystic common bile duct exploration. Operative exploration demonstrated a large remnant gallbladder and a partially obstructed cystic duct with many stones. Transcystic exploration with balloon extraction resulted in duct clearance. The procedure took 75 minutes, with minimal blood loss. The patient's postoperative course was uneventful. Final pathology results demonstrated a remnant gallbladder with cholelithiasis and cholecystitis. This report is the first in the literature to describe successful laparoscopic remnant cholecystectomy and transcystic common bile duct exploration after previous single-port cholecystectomy. Although inadvertent partial cholecystectomy is not unique to this technique, single-port laparoscopic procedures may result in different and significant complications.

Laparoscopy cholecystectomy for the surgical treatment of cholelithiasis has been considered the gold standard. The referred pain to the shoulder (omalgia) may be present to 63% of the patients and limits outpatient management. The study was to evaluate the usefulness of acetazolamide associated with ketorolac for reduction of the omalgia to minimally invasive treatment. We performed a clinical trial, randomized, double blind in patients undergoing laparoscopic cholecystectomy to assess the reduction of post-operative omalgia comparing ketorolac and ketorolaco+acetazolamida. 31 patients in each group were studied. The study group: 250 mg of acetazolamide before anesthetic induction and 30 mg of ketorolac in the immediate postoperative period. one tablet of placebo prior to the anesthetic induction and 30 mg of ketorolac in the immediate postoperative. The presence of omalgia was assessed using the analog visual scale. The variables recorded included: age, sex, flow of carbon dioxide intra-abdominal pressure, surgical time, urgent or elective surgery, omalgia, severity of pain evaluated by analog visual scale, addition analgesia. Both groups were homogeneous and statistical analysis showed no differences in the variables studied. The omalgia in the study group was presented at 9.67% and in the group control was the 58.06% (p < 0.001). 250 mg oral acetazolamide associated 30 mg of ketorolac reduces significantly the development of omalgia in patients undergoing laparoscopic cholecystectomy.

Full Text Available Background and Objective: Laparoscopic cholecystectomy has been the default operation for cholelithiasis at Federal Medical Centre, Owerri for the past 2 years and the outcomes have been good. The duration of post operative stay has been decreasing. We therefore initiated a preliminary 2-year prospective study in May 2010 to determine the feasibility of carrying out day case laparoscopic cholecystectomy in our hospital. Materials and Methods: Patients undergoing laparoscopic cholecystectomy were included in the study if they satisfied the following criteria: Age < 65 years, body mass index < 35 kg/m 2 , American Society of Anaesthesiology physical status class I and II, patient residence within 20 km radius of the hospital, patient acceptance of the procedure and absence of previous complicated upper abdominal surgery. Results: Twelve patients (10 females, 2 males were worked up with the intent of achieving same-day discharge of the patients. Five of the patients (41.7% were discharged on the day of operation. The reasons for overnight stay included inadequate pain control, insertion of drain and patient wishes. There was no conversion to open surgery, no major complications and no case of readmission to the hospital. Conclusions: Day case laparoscopic cholecystectomy in our environment could be safely promoted but will depend on improved facilities and patient enlightenment.

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. 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. 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 in peer-reviewed journals and presented at relevant

In patients with stones in their bile ducts and gallbladders, cholecystectomy is generally recommended after endoscopic sphincterotomy and clearance of bile duct stones. However, only approximately 10% of patients with gallbladders left in situ will return with further biliary complications. Expectant management is alternately advocated. In this study, we compared the treatment strategies of laparoscopic cholecystectomy and gallbladders left in situ. We randomized patients (>60 years of age) after endoscopic sphincterotomy and clearance of their bile duct stones to receive early laparoscopic cholecystectomy or expectant management. The primary outcome was further biliary complications. Other outcome measures included adverse events after cholecystectomy and late deaths from all causes. One hundred seventy-eight patients entered into the trial (89 in each group); 82 of 89 patients who were randomized to receive laparoscopic cholecystectomy underwent the procedure. Conversion to open surgery was needed in 16 of 82 patients (20%). Postoperative complications occurred in 8 patients (9%). Analysis was by intention to treat. With a median follow-up of approximately 5 years, 6 patients (7%) in the cholecystectomy group returned with further biliary events (cholangitis, n = 5; biliary pain, n = 1). Among those with gallbladders in situ, 21 (24%) returned with further biliary events (cholangitis, n = 13; acute cholecystitis, n = 5; biliary pain, n = 2; and jaundice, n = 1; log rank, P = .001). Late deaths were similar between groups (cholecystectomy, n = 19; gallbladder in situ, n = 11; P = .12). In the Chinese, cholecystectomy after endoscopic treatment of bile duct stones reduces recurrent biliary events and should be recommended.

This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

The aim of the study was to make a comparison between skin incisions made with electrocautery versus scalpel in terms of their safety, efficacy and post-operative complications. Design: A randomized controlled study. Setting: The study was conducted in Combined Military Hospital (CMH) Kharian, Pakistan airforce (PAF) Hospital Sargodha. Duration of Study: May 2008 to August 2011. Patients and Methods: Ninety seven patients who underwent open cholecystectomy were randomly divided into two groups on the basis of the use of electrocautery versus steel scalpel for making skin incision and sub-cutaneous tissue dissection. Parameters recorded were, time taken from skin incision to full incising of the peritoneum, length of the wound, amount of blood loss during this step of surgery in each group. Post-operative pain scoring using visual analogue scale was done. Wound complications such as infection, haematoma/seroma and dehiscence were noted too. One month of follow up was recorded in each group. Subsequently a comparison of these findings was done. Results: Incision time (sec/cm/sub 2/) was longer in scalpel group than in diathermy group (p = 0.001), whereas, incision blood loss (ml/cm/sub 2/) was significantly less in diathermy group than in scalpel group (p = 0.03). There was no difference in post-operative pain perception as delineated by visual pain analogue scoring system between the two groups (p = 0.57). Post-operative wound complications and the final healing of wound at 01 month of follow-up were almost similar in both groups. Conclusion: Electrocautery may be used safely without any untoward complication in making skin incision and sub-cutaneous tissue dissection with an advantage of reduced incision time and and less blood loss.

2017-11-01

Full Text Available BACKGROUND This study aimed at assessing the outcome of laparoscopic cholecystectomy (LC by determining the frequency of complications, especially of bile duct injuries. MATERIALS AND METHODS The case files of all patients undergoing laparoscopic cholecystectomy between January 2008 and December 2016 at Government General Hospital, Kakinada were retrospectively analysed. We evaluated the data according to outcome measures, such as bile duct injury, morbidity, mortality and numbers of patients whose resections had to be converted from laparoscopic to open. RESULTS During the eight years (January 2008 and December 2016, 336 patients underwent LC for chronic cholecystitis (CC, of whom 22 (6.5% developed complications. Among those who developed complications, two patients had major bile duct injuries (0.4%; 43 other patients (12.8% had planned laparoscopic operations converted to open cholecystectomy intra-operatively. None of the patients in this study died as a result of LC. CONCLUSION Bile duct injury is a major complication of LC. Anatomical anomalies, local pathology, and poor surgical techniques are the main factors responsible. The two patients who had severe common bile duct injury in this study had major anatomical anomalies that were only recognized during surgery.

Full Text Available Various strategies have been proposed for the management of retained calculi within the biliary tree following cholecystectomy. We present a unique case of a cystic duct remnant calculus causing Mirizzi syndrome, only the fourth such case of its kind. An open procedure was planned, however the calculus was eventually extracted endoscopically. The pathophysiology and management of Mirizzi syndrome and retained calculi within the cystic duct remnant are discussed along with the merits of a minimally invasive approach.

Full Text Available Background: Evidence regarding gender affecting the response to pain and its treatment is inconsistent in literature. The objective of this prospective, observational study was to determine the effect of gender on pain perception and postoperative analgesic consumption in patients undergoing laparoscopic cholecystectomy. Materials and Methods: We recruited 60 male and 60 female patients undergoing elective laparoscopic cholecystectomy. Patients were observed for additional intraoperative and postoperative analgesia. Numerical rating scale was documented at 10 min interval for 1 h in post-anesthesia recovery room and at 4, 8, and 12 h postoperatively. Boluses of tramadol given as rescue analgesia were also noted. There were no dropouts. Results: The mean pain scores were significantly higher in female patients at 20 and 30 min following surgery. Mean dose of tramadol consumption was significantly higher in female patients for the first postoperative hour (P = 0.002, but not in the later period. Conclusion: Female patients exhibited greater intensity of pain and required higher doses of analgesics compared to males in in the immediate postoperative period in order to achieve a similar degree of analgesia.

Recent studies have suggested higher complication and conversion to open rates for nighttime laparoscopic cholecystectomy (LC) and recommend against the practice. We hypothesize that patients undergoing night LC for acute cholecystitis have decreased hospital length of stay and cost with no difference in complication and conversion rates. A retrospective review of patients with acute cholecystitis who underwent LC from October 2011 through June 2015 was performed. Complication rates, length of stay, and cost of hospitalization were compared between patients undergoing day cholecystectomy and night cholecystectomy. Complication rates and costs did not differ between the day and night groups. Length of stay was shorter in the night group (2.4 vs 2.8 days, p = 0.002). Performing LC for acute cholecystitis during night-time hours does not increase risk of complications and decreases length of stay. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Introduction: Postoperative pain as an important medical concern is usually treated by opioids which also are of various inevitable side effects. The aim of this study was to assess the efficacy of multimodal preincisional premedication on preventing post-cholecystectomy acute pain. Methods: In a randomized clinical trial, sixty patients undergoing open cholecystectomy were randomized into two groups. Before anesthesia induction, Diclofenac suppository (100 mg and oral Clonidine (0.2 mg were administered in the first group. Immediately before operation, patients received Ketamine (1 mg/kg IV while the control group received placebo. The site of incision was infiltrated by the surgeon with 20 mL Bupivacaine 0.25% in both groups. Anesthesia induction and maintenance were similar in both groups. The severity of pain was recorded 2, 4, 6, 12, 24 and 48 hours after operation according to Visual Analogue Scale. Results: The severity of pain at two defined stages (6 and 12 hours later was significantly less in the intervention group than the control group (P<0.005. The average pain severity score was less than the control group (P<0.005. Conclusion: In our study, the administration of Clonidine, Diclofenac and Ketamine and bupivacaine infiltration to the site of incision, altogether was associated with a significant decrease in pain score and opioid requirement after cholecystectomy in comparison to bupivacaine infiltration to the site of incision.

Percutaneous transhepatic gallbladder drainage (PTGBD) is a procedure to resolve acute cholecystitis (AC). It may decrease the technical difficulty of laparoscopic cholecystectomy (LC) and thus may facilitate successful surgery when a patients' condition improves. However, the timing of LC after PTGBD remains controversial. From 2004 to 2010, cholecystectomy after PTGBD was performed in 67 patients with AC. Group I members underwent LC within 72 h of PTGBD (n = 21), whereas group II members underwent LC at more than 72 h after PTGBD (n = 46). The open conversion rate was similar in the two groups. The perioperative complication rate was higher in group I than in group II, but with marginal significance (19.0 vs. 4.3%; p = 0.07). Mean operative time was longer in group I than in group II (79.3 ± 25.3 vs. 53.7 ± 45.3 min; p = 0.02). However, overall hospital stay was shorter in group I than in group II, but with marginal significance (10.8 ± 4.5 vs. 14.7 ± 9.3 days; p = 0.08). Pros and cons were well balanced between the two groups. Decisions on the timing of cholecystectomy after PTGBD should be made based on considerations of patient condition, hospital facilities, and surgical experience.

This present study sought to review the feasibility and patients' satisfaction of laparoscopic cholecystectomy to be perform as daycare procedure. Sixty-two patients with symptomatic gallstones were recruited within a year. They were randomized into overnight stay and daycare groups. The outcomes and post-operative complications were analyzed. Fifty-eight patients were eligible for analysis and four patients were excluded because of conversion to open cholecystectomy. All patients in daycare group reported no fever but two patients in the overnight stay group complaint of post-operative fever (p=0.150). The mean pain score using Visual Analogue Score (VAS) in daycare group was 2.93 but in the overnight stay was recorded as 3.59 (p=0.98). Five patients had post-operative nausea and vomiting (PONV) in daycare group compared to 2 patients in the overnight stay group (p=0.227). Patient's satisfaction were higher in the daycare group (p=0.160). All patients in daycare group were back at work within a week but in overnight stay, 11 patients had to stay off work for more than one week (p=0.01). Daycare laparoscopic cholecystectomy is safe and feasible. The satisfaction of daycare surgery is higher than overnight stay group. Patients' selection is an important aspect of its success.

Full Text Available Background: A major challenge in the postoperative period is pain management which, if not adequately controlled, may contribute to patient discomfort and decreased patient satisfaction, and possibly increased morbidity and mortality. Both Thoracic paravertebral block and oblique subcostal transversus abdominis plane block can be used as analgesic techniques for abdominal surgeries. Our aim in this research was comparison of cumulative 24-h post-operative morphine consumption between ultrasound-guided oblique subcostal transversus abdominis plane block and ultrasound-guided thoracic paravertebral block in patients who underwent an open cholecystectomy under general anesthesia. Patients and methods: This study was performed on 46 patients who underwent open cholecystectomy under general anesthesia. All patients were randomly allocated alternatively to one of two equal groups to either undergo ultrasound-guided unilateral oblique subcostal transversus abdominis plane block Group (I or to undergo ultrasound-guided unilateral thoracic paravertebral block Group (II. Both groups were subjected to a similar analgesic regimen in the immediate post-operative period that involved intravenous patient-controlled morphine analgesia which was used in both groups. Results: The total morphine consumption in the first postoperative 24 h was lower in thoracic paravertebral block Group (II (9.9 mg in thoracic paravertebral block group vs. 15.4 mg in oblique subcostal transversus abdominis plane block Group (I with p < 0.001. The mean time of first request of analgesia in Group (I was 248.7 min compared to 432.1 for Group (II with p < 0.001. Conclusions: Both ultrasound-guided oblique subcostal transversus abdominis plain block and single injection ultrasound guided thoracic paravertebral block are effective analgesic techniques for upper abdominal surgeries and reduces postoperative opioid requirements. However, thoracic paravertebral block is more

.01). SWS was absent in four of the patients after operation, whereas in six patients it was within the normal range (5-20% of the night). The proportion of rapid eye movement (REM) sleep was not significantly changed after operation. There were no changes in arterial oxygen saturation on the postoperative...... compared with the preoperative night. Comparison of our results with previous studies on SWS and REM sleep disturbances after open laparotomy, suggests that the magnitude of surgery or administration of opioids, or both, may be important factors in the development of postoperative sleep disturbances.......The sleep pattern and oxygenation of 10 patients undergoing laparoscopic cholecystectomy were studied on the night before operation and the first night after operation. Operations were performed during general anaesthesia and postoperative analgesia was achieved without the administration...

2015-01-01

The aim of this study was to assess the analgesic efficacy of Bupivacaine application at port-site and intraperitoneal infiltration in patients with laparoscopic cholecystectomy. Study Design: Randomized Controlled Clinical Trial. Place and Duration: The study was conducted at Rehman Medical Institute (RMI) Peshawar, Pakistan from June 2009 to June 2012. Materials and Methods: Patients who underwent elective laparoscopic cholecystectomy during the study period were included in the study. Eighty patients were randomized into two groups, study group and control group. The study group received 40 ml of 0.25% bupivacaine intraoperatively as intraperitoneal infiltration and local infiltration at the port sites. Pain assessment was done using visual analogue pain score (VAS) of 0-10 at fixed intervals during the first 24 hours post surgery. Results: The mean VAS score in the study group was less as compared to the control group throughout the 24 hours assessment period, however this difference was statistically significant (p<0.001) only during the first three assessments at 1 hour, 4 hours and 8 hours post surgery. The analgesia requirement was also significantly (p<0.001) decreased in the study group. Conclusion: Port site and intraperitoneal application of local anesthetic bupivacaine significantly reduced pain during the first 8 hours post surgery and total analgesia requirement was also significantly reduced. It is a simple and easily applicable technique which increases patient comfort and can be safely used to decrease post operative pain in patients undergoing laparoscopic cholecystectomy. (author)

The best method to ligate the arteries during laparoscopic cholecystectomy or appendectomy remains controversy. The aim of this study is to introduce a new approach during laparoscopic combined cholecystectomy and appendectomy using a monopolar electrocautery to seal the cystic and appendix arteries. We retrospectively reviewed data from 57 patients who underwent laparoscopic combined cholecystectomy and appendectomy between December 2006 and June 2016. Each laparoscopic combined cholecystectomy and appendectomy was performed by coagulating and sealing the cystic and appendix arteries. Absorbable clip or coils were then used to ligate the proximal of cystic duct and the stump of appendix. The other side of the cystic duct and appendix which subsequently were to be removed from abdomen were used titanium clips or silk ligature. Of the 57 patients, 3 patients (5.3%) were converted to open surgery due to severe abdominal adhesions or gallbladder perforation. The mean operative time was 56 minutes (range, 40-80 minutes). Mean blood loss was 12 mL (range, 5-120 mL), and the mean postoperative hospital stay was 3.0 days (range, 2-5 days). No postoperative bleeding, biliary leakage, infection, or mortality occurred. Monopolar electrocautery to seal the cystic and appendix arteries is a safe, effective, and economical surgical procedure during laparoscopic combined cholecystectomy and appendectomy. Further randomized controlled clinical trials are required to validate our findings.

In this prospective, clinical study, four groups, each consisting of 12 patients were established to determine how gastric emptying is influenced in cholelithiasis with accompanied flatulent dyspepsia and the relationship of symptoms and gastric emptying after cholecystectomy: group 1--healthy people; group 2--patients with dyspeptic cholelithiasis; group 3--patients with no dyspepsia after cholecystectomy; group 4--patients with dyspepsia after cholecystectomy. Groups are compared according to solid phase gastric emptying scintigraphies performed with Tc 99m sulphur colloid bound with scrambled eggs. Gastric emptying delayed in groups 2 (P 0.005). These results demonstrate that dyspepsia, in cholelithiasis and persisting after cholecystectomy, has a close relation with delay in gastric emptying.

Difference analysis of ambulatorization rate, pain, analgesic requirements and daily activities recovery in patients undergoing laparoscopic cholecystectomy with standard multiport access (CLMP) versus a minilaparoscopic, 3mm size, technique. Prospective randomized trial of 40 consecutive patients undergoing laparoscopic cholecystectomy. Comparison criteria included predictive ultrasound factors of difficult cholecystectomy, previous history of complicated biliary disease and demographics. Results are analyzed in terms of ambulatorization rate, pain, analgesic requirements, postoperative recovery, technical difficulty, hemorrhage intensity, overnight stay, readmission rate and total or partial conversion. Both procedures were similar in surgery time, technical score and hemorrhage score. MLC was associated with similar ambulatorization rate, 85%, and over-night stay 15%, with only 15% partial conversion rate. MLC showed less postoperative pain (P=.026), less analgesic consumption (P=.006) and similar DAR (P=.879). MLC is similar to CLMP in terms of ambulatorization with less postoperative pain and analgesic requirements without differences in postoperative recovery. Copyright © 2014 AEC.

Although single-incision laparoscopic cholecystectomy is now widely performed in patients with cholecystitis, some cases require an additional port to complete the procedure. In this study, we focused on risk factor of additional port in this surgery. We performed single-incision cholecystectomy in 75 patients with acute cholecystitis or after cholecystitis between 2010 and 2014 at Gunma University Hospital. Surgical indications followed the TG13 guidelines. Our standard procedure for single-incision cholecystectomy routinely uses two needlescopic devices. We used logistic regression analysis to identify the risk factors associated with use of an additional full-size port (5 or 10 mm). Surgical outcome was acceptable without biliary injury. Nine patients (12.0%) required an additional port, and one patient (1.3%) required conversion to open cholecystectomy because of severe adhesions around the cystic duct and common bile duct. In multivariate analysis, high C-reactive protein (CRP) values (>7.0 mg/dl) during cholecystitis attacks were significantly correlated with the need for an additional port (P = 0.009), with a sensitivity of 55.6%, specificity of 98.5%, and accuracy of 93.3%. This study indicated that the severe inflammation indicated by high CRP values during cholecystitis attacks predicts the need for an additional port. J. Med. Invest. 64: 245-249, August, 2017.

There were 20 conversions among emergency patients and 12 conversions amongelective patients. On average the decision to convert was made in the 35th min of the operation. The shortest time toconversion was 15 min and the longest was 90 min. Five conversions were performed in the 25th and 35th minand 4 in the 20th, 30th, and 40th mine. Most frequently conversions occurred between the 20th and 40th min of theprocedure. Intentional conversions were performed in 27 patients. Adhesions and clumps around the gallbladder werethe cause of conversion in 10 patients and that was the most frequent reason for the operative modality change. Thenext cause of conversion was changes observed in the course of acute cholecystitis in the form of gallbladder empyemaor cholecystocele (9 patients. Small, fibrotic gallbladder, immersed in the liver, was the reason for conversion ina further 4 patients. In 4 cases the conversion was caused by difficulties in the identification of anatomical structures.Four cases of forced conversions and 1 anticipated conversion were found in the analysed material.Conclusions: A change of operative modality during laparoscopic cholecystectomy was made on average in 5.85% ofoperations. The average time before the conversion was 35 min. Emergency patients required a change of operativemodality 4 times more often. The most frequent were intentional conversions (84%, caused by pericystic adhesionsand by

Robotic application to cholecystectomy has dramatically increased, though its impact on cost of care and reimbursement has not been elucidated. We undertook this study to evaluate and compare cost of care and reimbursement with robotic versus laparoscopic cholecystectomy. The charges and reimbursement of all robotic and laparoscopic cholecystectomies at one hospital undertaken from June 2012 to June 2013 were determined. Operative duration is defined as time into and time out of the operating room. Data are presented as median data. Comparisons were undertaken using the Mann-Whitney U-test with significance accepted at p ≤ 0.05. Robotic cholecystectomy took longer (47 min longer) and had greater charges ($8,182.57 greater) than laparoscopic cholecystectomy (p depreciation, interest, and taxes (EBDIT), and Net Income were not impacted by approach. Relative to laparoscopic cholecystectomy, robotic cholecystectomy takes longer and has greater charges. Revenue, EBDIT, and Net Income are similar after either approach; this indicates that costs with either approach are similar. Notably, this is possible because much of hospital-based costs are determined by cost allocation and not cost accounting. Thus, the cost of longer operations and costs inherent to the robotic approach for cholecystectomy do not translate to a perceived financial burden.

From March 1992 to September 1994, 281 patients were submitted to laparoscopic cholecystectomy for cholelithiasis. 27 patients were admitted with diagnosis of acute cholecystitis and in 17 patients common duct stones were discovered and managed by ERCP before laparoscopic procedure. Surgical procedure was the standard one described by Cox. The mean duration of the operation was 60 minutes and was significantly related to the surgeon's experience; the incedence of conversion to open procedure was 5.7%. There was no postoperative mortality; the total morbility rate was 2.8%, with 3 major complications, and 5 minor complications.

Rules and technical tricks in extremely difficult laparoscopic cholecystectomies

Full Text Available We remind you of some technical artifices required in order to resolve difficult cases, such as: antegrade laparoscopic cholecystectomy (LC, subtotal laparoscopic cholecystectomy (SLC and the “stairs” clipping of the cystic duct. Also we acknowledge the closing of the cystic duct. We analyzed the medical records of 15251 laparoscopic cholecystectomies performed during 1994-2015, with emphasis on: surgical technique, conversion rate, hemorrhage, postoperative bile leaking, iatrogenic MBD injuries and mortality. We divided the cases in 5 study groups, group 1 (1994- 2004 N= 5138, group 2 (2005-2015 N= 10113, group 3 (fundus first cholecystectomies, N=2348, group 4 (retrograde cholecystectomies, N=12889 and group 5 (subtotal laparoscopic cholecystectomy-SLC, N=14 which we compared regarding the main parameters. We prefer to perform a “step by step” clipping each time the length of the clip does not cover all the circumference of the cystic duct. This artifices, is a simple laparoscopic gesture easy to perform and has the advantage of avoiding a large excessive and risky laparoscopic dissection in the vicinity of the main biliary duct. More seldom we appeal to the suture of the cystic stump using the intracorporeal knots or a simple stump ligation with an extracorporeal preformed not. We did not encounter any late or early complications following the implementation of this technical laparoscopic artifice. Laborious laparoscopic cholecystectomies performed by a well-trained surgical team ensure the premises of a good performance even while adopting laparoscopic ingenious and difficile gestures that also respect the intraoperatory rules and principals.

The aim of this study was to determine whether early laparoscopic cholecystectomy (LC) is safe and feasible for patients diagnosed with moderate (grade 2) and severe (grade 3) acute cholecystitis (AC) according to the Tokyo Guidelines 2013 (TG13). Early cholecystectomy is the current accepted standard of care for patients with mild (grade 1) and selected grade 2 AC based on TG13. For selected grade 2 and grade 3 AC, early percutaneous cholecystostomy (PC) followed by delayed cholecystectomy is recommended. Patients diagnosed with AC over a 14-month period were identified and divided into three grades of AC based upon chart review using the grading and severity indicators according to TG13. A total of 149 patients underwent emergency LC. Eighty-two (55 %) patients were male. Eighty-four (56.4 %) patients were classified as grade 1 AC, 49 (32.9 %) as grade 2, and 16 (10.7 %) as grade 3. Eighty-three (98.8 %) patients with grade 1 AC underwent emergency LC, and 1 patient (1.2 %) underwent PC followed by emergency LC. The median length of hospital stay for grade 1 AC patients was 2 (1-11) days. There were 2 (2.4 %) readmissions with fever and no additional complications. Among the 65 patients identified with grade 2 or 3 AC, 6 (9.2 %) underwent PC followed by emergency LC. Fifty-nine (90.8 %) patients underwent emergency cholecystectomy: 58 (98.3 %) LC and one (1.7 %) open cholecystectomy. Among the 58 patients with LC, 3 (5.2 %) patients had open conversion and 10 (17.2 %) patients required subtotal cholecystectomy. One patient was converted to open due to bile duct injury and had hepaticojejunostomy repair. Two other patients were converted due to dense adhesions and inability to safely dissect Calot's triangle. The median length of hospital stay was 4 (1-28) days. There was one readmission for ileus. Severity grading of AC is not the sole determinant of early LC. Patient comorbidity also impacts clinical decision. Confirmation in a larger cohort is

Cholelithiasis is one of the most common disorders of the digestive tract encountered by general surgeons worldwide. Conventional or open cholecystectomy was the mainstay of treatment for a long time for this disease. In the 1980s laparoscopic surgery revolutionized the management of biliary tract diseases. It brought about a revolutionary change in the basic concepts of surgical principles and minimal access surgery gradually started to be acknowledged as a safe means of carrying out surgeries. To investigate the technical feasibility, safety and benefit of Single Incision Laparoscopic Cholecystectomy (SILC) versus Conventional Four Port Laparoscopic Cholecystectomy (C4PLC). This prospective randomized control trial was conducted to compare the advantages if any between the SILC and C4PLC. Thirty two patients underwent SILC procedure and C4PLC, each. The age of the patients ranged from 16-60years. Other demographic data and indications for cholecystectomy were comparable in both the groups. Simple comparative statistical analysis was carried out in the present study. Results on continuous variables are shown in Mean ± SD; whereas results on categorical variables are shown in percentage (%) by keeping the level of significance at 5%. Intergroup analysis of the various study parameters was done by using Fisher exact test. SPSS version 22 was used for statistical analysis. The mean operating time was higher in the SILC group (69 ± 4.00 mins vs. 38.53 ± 4.00 mins) which was of statistical significance (p=post-operative pain, with lesser analgesic requirements (p=operating time was longer otherwise it has almost similar clinical outcomes to those of C4PLC.

Full Text Available Since its introduction at the end of the 20th century, laparoscopic cholecystectomy has evolved into a safe and convenient minimally invasive surgical method, which is now the gold standard therapy for cholelithiasis worldwide. Physicians have continued to improve upon the procedure, creating methods that further minimize the related scarring and pain, such as the laproendoscopic single-site cholecystectomy and the gasless-lift laparoscopy. Additionally, the primary challenge of limited operative space in these procedures remains a key feature requiring improvement. In this review, the development and progression of laparoscopic cholecystectomy over the past 26 years is discussed, highlighting the current advantages and disadvantages that need to be addressed by practicing physicians to maximize the clinical value of this important therapy.

Full Text Available Available evidence of the relationship between cholelithiasis, cholecystectomy, and risk of liver cancer and hence we conducted a meta-analysis to investigate the relationships. PubMed, EMBASE, and ISI Web of Knowledge were searched to identify all published cohort studies and case-control studies that evaluated the relationships of cholelithiasis, cholecystectomy and risk of liver cancer and single-cohort studies which evaluated the incidence of liver cancer among patients who understood cholecystectomy (up to February 2013. Comprehensive meta-analysis software was used for meta-analysis. A total of 11 observational studies (six cohort studies and five case-control studies were included in this meta-analysis. The result from meta-analysis showed that cholecystectomy (risk ratio [RR]: 1.59, 95% confidence interval [CI]: 1.01-2.51, I2 = 72% and cholecystolithiasis (RR: 5.40, 95% CI: 3.69-7.89, I2 = 93% was associated with more liver cancer, especially for intrahepatic cholangiocarcinoma (ICC (cholecystectomy: RR: 3.51, 95% CI: 1.84-6.71, I2 = 26%; cholecystolithiasis: RR: 11.06, 95% CI: 6.99-17.52, I2 = 0%. The pooled standardized incidence rates (SIR of liver cancer in patients who understood cholecystectomy showed cholecystectomy might increase the incidence of liver cancer (SIR: 1.57, 95% CI: 1.13-2.20, I2 = 15%. Based on the results of the meta-analysis, cholecystectomy and cholecystolithiasis seemed to be involved in the development of liver cancer, especially for ICC. However, most available studies were case-control studies and short-term cohort studies, so the future studies should more long-term cohort studies should be well-conducted to evaluate the long-term relationship.

Aim of this study is the evaluation of the impact of preoperative informative session using a Multimedia Health Educational Program (MHEP) on patients undergoing elective Laparoscopic Cholecystectomy (LC) for cholelithiasis, preoperative anxiety and postoperative pain and nausea. Sixty consecutive patients scheduled for elective LC were considered for enrollment in the trial. Patients were assigned randomly to four groups: Group A included 15 patients, preoperatively informed regarding LC through the MHEP presented by a Registered Nurse (RN). Group B included 15 patients preoperatively informed through a leaflet (designed and developed using the exact contents of the MHEP). In Group C, there were 15 patients who were being informed verbally from the RN. Finally, the control Group D included 15 patients, who had the conventional preoperative information about the operation and postoperative course by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, C. Preoperative assessment of patient's knowledge about cholelithiasis and LC was performed after informative session, and was based on a specifically developed "closed, true-false" questionnaire. Preliminary results suggest that conventional information provided by the attending surgeon (Group D) is inadequate. Specifically developed informative sessions with the contribution of MHEP seems to be effective on reducing preoperative anxiety and postoperative pain, in patients undergoing elective LC.

The educational technology of massive open online courses (MOOCs) has been successfully applied in a wide variety of disciplines and are an intense focus of educational research at this time. Educators are now looking to MOOC technology as a means to improve professional medical education, but very little is known about how medical MOOCs compare with traditional content delivery. A retrospective analysis of the course evaluations for the Medicine as a Business elective by fourth-year medical students at Southern Illinois University School of Medicine (SIU-SOM) for the 2012-2015 academic years was conducted. This course was delivered by small group flipped classroom discussions for 2012-2014 and delivered via MOOC technology in 2015. Learner ratings were compared between the two course delivery methods using routinely collected course evaluations. Course enrollment has ranged from 6-19 students per year in the 2012-2015 academic years. Student evaluations of the course are favorable in the areas of effective teaching, accurate course objectives, meeting personal learning objectives, recommending the course to other students, and overall when rated on a 5-point Likert scale. The majority of all student ratings (76-95%) of this elective course are for the highest possible choice (Strongly agree or Excellent) for any criteria, regardless if the course was delivered via a traditional or MOOC format. Statistical analysis of these ratings suggests that the Effective Teacher and Overall Evaluations did not statistically differ between the two delivery formats. Student ratings of this elective course were highly similar when delivered in a flipped classroom format or by using MOOC technology. The primary advantage of this new course format is flexibility of time and place for learners, allowing them to complete the course objectives when convenient for them. The course evaluations suggest this is a change that is acceptable to the target audience. This study suggests that

Pain control after a laparoscopic cholecystectomy can represent a challenge, considering the side effects due to standard analgesia methods. Recently the transversus abdominis plane block (TAP Block) has been used as a part of multimodal analgesia with promising results. The subcostal approach (OSTAP Block), a variant on the TAP block, produces reliable unilateral supraumbilical analgesia. This study evaluated the efficacy of the OSTAP block with bupivacaine in laparoscopic cholecystectomy compared with the placebo OSTAP block. Sixty ASA I/II adult patients listed for elective laparoscopic cholecystectomy were randomly allocated in one of two groups: Group A (OSTAP placebo) received preoperatively bilateral OSTAP block with sterile normal saline and Group B (OSTAP bupivacaine) received bilateral preoperatively OSTAP block with the same volumes of 0.25% bupivacaine. Twenty-four hours postoperative opioid consumption, the dose of opioid required during surgery, opioid dose in the recovery unit (PACU) and PACU length of stay were evaluated. The quality of analgesia was assessed by the Visual Analogue Scale (VAS) at specific interval hours during 24 h, at rest and with movement. The mean intraoperative opioid consumption showed a significant difference between the two groups, (385 ± 72.52 mg in group A vs 173.67 ± 48.60 mg in group B, p consumption showed a statistically significant difference between groups (32 ± 26.05 mg vs 79 ± 16.68 mg, p < 0.001). PACU length of stay was significantly lower for group B patients compared with group A patients (20.67 ± 11.27 min vs 41.67 ± 12.41 min, p < 0.001). The OSTAP bupivacaine group had a statistically significant lower pain score than the OSTAP placebo group at 0, 2, 4, 6, 12, 24 h, both at rest and with movement. No signs or symptoms of local anaesthetic systemic toxicity or other complications were detected. OSTAP block with bupivacaine 0.25% can provide effective analgesia up to 24 hours after laparoscopic

Routine testing of liver function before and after elective laparoscopic cholecystectomy: is it necessary?

LENUS (Irish Health Repository)

Ahmad, Nasir Zaheer

2012-01-31

BACKGROUND AND OBJECTIVES: Liver function tests (LFTs) include alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and bilirubin. The role of routine testing before and after laparoscopic cholecystectomy was evaluated in this study. PATIENTS AND METHODS: A total of 355 patients were retrospectively analyzed by examining the LFTs the day before, the day after, and 3 weeks after the surgery. The Wilcoxon signed-rank test and Student t test were performed to determine statistical significance. RESULTS: Alterations in the serum AST, ALT, and GGT were seen on the first postoperative day. Minor changes were seen in bilirubin and ALP. An overall disturbance in the LFTs was seen in more than two-thirds of the cases. Repeat LFTs performed after 3 weeks on follow-up were found to be within normal limits. CONCLUSION: Mild-to-moderate elevation in preoperative LFTs may not be associated with any deleterious effect, and, in the absence of clinical indications, routine preoperative or postoperative liver function testing is unnecessary.

Cirrhotic patients have been known to be more affected with gallstones than their non-cirrhotic counterparts; since laparoscopy was introduced, it has been generally approved as the standard approach for cholecystectomies with the exception of end-stage cirrhosis. The purpose of this study was to evaluate the safety and efficacy of clipless laparoscopic cholecystectomy using the harmonic scalpel in complicated cholelithiasis in cirrhotic patients. This prospective study was conducted on 62 cirrhotic patients presenting to the Gastrointestinal Surgery Unit in Alexandria Main University Hospital with complicated gallstones between March 2013 and March 2016. Both intraoperative time and blood loss were calculated in addition to rates of conversion to open cholecystectomy, morbidity and mortality. Most of our cases were females with a ratio of 1.7:1, with a mean age of 45.21 years, ranging from 25 to 65 years. The most common cause of cirrhotic liver was hepatitis C in 45.1% of patients. Among the 62 patients included in the study, 56 patients (90.3%) were presenting with acute cholecystitis and six patients were operated at the onset of acute biliary pancreatitis. The mean operative time was 72.9 min with mean blood loss 45.45 mL. The study concluded safety of total clipless laparoscopic cholecystectomy using a harmonic scalpel in Child A and B type cirrhotic patients, who presented with complicated gallstones. © 2017 Royal Australasian College of Surgeons.

To develop and validate an "in house" risk model for predicting perioperative mortality following elective AAA repair and to compare this with other models. Multivariate logistics regression analysis was used to identify risk factors for perioperative-day mortality from one tertiary institution's prospectively maintained database. Consecutive elective open (564) and endovascular (589) AAA repairs (2000-2010) were split randomly into development (810) and validation (343) data sets. The resultant model was compared to Glasgow Aneurysm Score (GAS), Modified Customised Probability Index (m-CPI), CPI, the Vascular Governance North West (VGNW) model and the Medicare model. Variables associated with perioperative mortality included: increasing age (P = 0.034), myocardial infarct within last 10 years (P = 0.0008), raised serum creatinine (P = 0.005) and open surgery (P = 0.0001). The areas under the receiver operating characteristic curve (AUC) for predicted probability of 30-day mortality in development and validation data sets were 0.79 and 0.82 respectively. AUCs for GAS, m-CPI and CPI were poor (0.63, 0.58 and 0.58 respectively), whilst VGNW and Medicare model were fair (0.73 and 0.79 respectively). In this study, an "in-house" developed and validated risk model has the most accurate discriminative value in predicting perioperative mortality after elective AAA repair. For purposes of comparative audit with case mix adjustments, national models such as the VGNW or Medicare models should be used. Copyright © 2012 European Society for Vascular Surgery.

Electrocautery remains the main energy form used for dissection in laparoscopic cholecystectomy. However, due to its many risks the search continues for safer and more efficient forms of energy. This chapter assesses the outcomes of dissection using ultrasonic energy as compared to monopolar electrocautery during laparoscopic cholecystectomy. Studies included are trials of prospectively randomized adult patients with symptomatic gallstone disease subject either ultrasonic or monopolar electrocautery dissection during laparoscopic cholecystectomy. Seven trials were included in this review, with a total patient number of 695 randomized to two dissection methods: 340 in the electrocautery group and 355 in the ultrasonic group. Ultrasonic dissection is shown to be superior to monopolar electrocautery in laparoscopic cholecystectomy. Disadvantages include a difficult maneuvering technique and overall cost. Appropriate training programs may be implemented to overcome the first disadvantage, and it might be argued that given the combined cost of factors associated with standard clip and cautery technique, cost issues may be outweighed by the benefits of ultrasonic dissection. However, this necessitates further cost-benefit analysis.

STUDY OBJECTIVES: To compare the prophylactic antiemetic efficacy of the combination of ondansetron and droperidol with that of droperidol alone in patients undergoing elective laparoscopic cholecystectomy. DESIGN: Randomized, double-blind controlled trial. University affiliated teaching hospital after induction of standardized general anesthesia. PATIENTS: 64 ASA physical status I or II patients aged 18 to 80 years, undergoing elective laparoscopic cholecystectomy. INTERVENTION: Following induction of general anesthesia, patients received either droperidol 1.25 mg intravenously (IV; n = 30; Group D) or the combination of droperidol 1.25 mg IV and ondansetron 4 mg IV (n = 34; Group D+O). MEASUREMENTS: Number and severity of nausea episodes, number of emetic episodes, total analgesic consumption, and rescue antiemetic administration were assessed at 1, 3, and 24 hours after admission to the recovery room. Data were analyzed using Fisher\\'s Exact test and unpaired Student\\'s t-test; a p-value <0.05 was considered significant. RESULTS: The proportions of patients who experienced nausea (70% and 53% for D and D+O groups, respectively) and vomiting (30% and 19% for D and D+O groups, respectively) were similar in the two groups. The frequency of moderate and severe nausea (requiring administration of antiemetic) was less in group D + O (7%) compared with group D (19%; p < 0.05). CONCLUSIONS: Patients who received the combination of droperidol and ondansetron experienced less severe nausea compared with patients who received droperidol alone.

Objective: To investigate the effects of laparoscopic cholecystectomy on the plasma levels of endothelin and calcitonin gene-related peptide (CGRP)in elderly patients. Methods: Sixty patients undergoing elective laoaroscopic cholecystectomy were divided into 65 years old group according to their ages (30 cases in each group). The plasma levels of endothelin and CGRP were measured before surgery, after intubation, at the time of gallbladder removal, immediately after surgery and 24 hours after surgery by radioimmunoassay. Results: There was no significant difference in endothelin levels between the two groups before the surgery (t=0.971, P>0.05). The endothelin levels in both groups gradually increased after the intubation, but more significantly in the > 65 years old group (t=4.258, P 65 years old group (t=5.134, P 65 years old group continued to increase, but it decreased in the 0.05). The CGRP levels had not significantly changed during the perioperative period in the 65 years old group, CGRP levels decreased after anaesthesia, but increased during the surgery, and then reached the highest level at the time of the surgery completed. CGRP levels were significant difference between the two groups after intubation and immediately after surgery (t=4.084 and t=4.085, P<0.05). Conclusion: The levels of endothelin and CGRP had significantly changed elderly patients than those in young patients, especially for endothelin. (authors)

Enterocutaneous fistula as a complication of laparoscopic cholecystectomy

Huddy Jeremy

2008-01-01

Full Text Available Laparoscopic cholecystectomy is the gold standard method for treating gallstone related disease. Despite its widespread and well established application, clear consensus is not arrived at regarding the comparative risks and benefits of acute versus interval cholecystectomy. The complications of this technique are well known, with respect to both the operative intervention and the technique used. This case describes a case of cholecystitis in a 76-year-old man, who underwent acute laparoscopic cholecystectomy for cholecystitis refractory to antibiotic therapy. Postoperative complications included subhepatic collections bilaterally, eventually leading to the formation of an enterocutaneous fistula to the left chest wall - a previously undocumented phenomenon. The protracted course of the disease is discussed, with reference to investigations performed and the eventual successful outcome.

Full Text Available Double gallbladder is a rare embryological anomaly of clinical significance. Despite availability of modern imaging, only 50% of recently reported cases had preoperative diagnosis, which is desirable in every case to avoid serious operative complications. Double pathology in double gallbladder is extremely rare with only 3 reporting′s available till date to the best of author′s knowledge. With a preoperative diagnosis of double gallbladder, laparoscopic cholecystectomy can be safely and successfully performed with meticulous dissection, aided by operative cholangiogram. However in all such attempts a lower threshold should be kept for conversion to open surgery. Awareness about this anomaly amongst radiologists and surgeons is of crucial importance. Double gallbladder does not present with any specific symptom, neither it increases disease possibility in either lobe. Prophylactic cholecystectomy has no role in asymptomatic cases diagnosed accidentally. Author reports a case of a symptomatic young male with double gallbladder who presented with short history of dyspepsia, abdominal pain and fever. Definite preoperative diagnosis was reached with ultrasound scan and magnetic resonance cholangio pancreatography and subsequently dealt with laparoscopically. Calculous cholecystitis affected one lobe and acalculous empyema the other. While the 1st lobe drained though a cystic duct into common bile duct (CBD, the 2nd was without any communication with either CBD or its counterpart, thus remained as a blind vesicle.

Full Text Available Aim: To evaluate the role of laparoscopic cholecystectomy (LC in the management of cholelithiasis in children. Methods: A retrospective review of our experience with LC for cholelithiasis at our institution, between April 2006 and November 2008, was done. Data included patient demographics, clinical history, hematological investigations, imaging studies, operative technique, postoperative complications, postoperative recovery, and final histopathological diagnosis. Results: During the study period of 32 months, 18 children (8 males and 10 females with cholelithiasis were treated by LC. The mean age was 9.4 years (range 3-18. Seventeen children had symptoms of biliary tract disease and 1 child had incidentally detected cholelithiasis during an ultrasonography of abdomen for unrelated cause. Only 5 (27.8% children had definitive etiological risk factors for cholelithiasis and the remaining 13 (75.2% cases were idiopathic. Sixteen cases had pigmented gallstones and 2 had cholesterol gallstones. All the 18 patients underwent LC, 17 elective, and 1 emergency LC. The mean operative duration was 74.2 min (range 50-180. Postoperative complications occurred in 2 (11.1% patients. The average duration of hospital stay was 4.1 days (range 3-6. Conclusion: Laparoscopic chloecystectomy is a safe and efficacious treatment for pediatric cholelithiasis. The cause for increased incidence of pediatric gallstones and their natural history needs to be further evaluated.

It has become increasingly important to expose surgical residents to robotic surgery as its applications continue to expand. Single-site robotic cholecystectomy (SSRC) is an excellent introductory case to robotics. Resident involvement in SSRC is known to be feasible. Here, we sought to determine whether it is safe to introduce SSRC to junior residents. A total of 98 SSRC cases were performed by general surgery residents between August 2015 and August 2016. Cases were divided into groups based on resident level: second- and third-years (juniors) versus fourth- and fifth-years (seniors). Patient age, gender, race, body mass index, and comorbidities were recorded. The number of prior laparoscopic cholecystectomies completed by participating residents was noted. Outcomes including operative time, console time, rate of conversion to open cholecystectomy, and complication rate were compared between groups. Juniors performed 54 SSRC cases, whereas seniors performed 44. There were no significant differences in patient age, gender, race, body mass index, or comorbidities between the two groups. Juniors had less experience with laparoscopic cholecystectomy. There was no significant difference in mean operative time (92.7 min versus 98.0 min, P = 0.254), console time (48.7 min versus 50.8 min, P = 0.639), or complication rate (3.7% versus 2.3%, P = 0.68) between juniors and seniors. SSRC is an excellent way to introduce general surgery residents to robotics. This study shows that with attending supervision, SSRC is feasible and safe for both junior and senior residents with very low complication rates and no adverse effect on operative time.

Full Text Available Objective: to contribute our experience for five years in the implemetation of outpatient laparoscopic cholecystectomy (LC. Patients: between January 1999 and March 2004 we performed 504 outpatient LCs. We applied both exclusion and inclusion criteria, an anesthetic and surgical protocol, and discharge-specific criteria. Postoperative management in "fast track" regime. Postoperative period controlled by protocol, including phone calls after cholecystectomy. Results: the ambulatory percentage in the global series was 88.8%, and mean hospital stay was 6.1 hours. Fifty-one patients required overnight stays (10.1%, most of them for "social" causes. Five patients required admission (between 24 and 48 hours for different causes (conversion to laparotomy, intraoperative neumothorax, and postoperative medical complications. Six patients (1.1% were readmitted, and we observed 11.6% postoperative complications in the global series, with abdominal parietal pain being most frequent. Phone localization by 22.00 p.m. in the same day of surgery was 100% complete for outpatient cases. Postoperative surveillance within the first month after surgery was completed in 93.9%, and within th first year in 86.7% of patients. Conclusions: outpatient LC is safe and feasible, and probably represents a new "gold standard" in the treatment of symptomatic cholelithiasis.

Full Text Available BACKGROUND: Dexmedetomidine a newer generation highly selective alpha - 2 adrenergic agonist are well known to inhibit catecholamine release. The present study compares the effects of intravenously administered dexmedetomidine to attenuate hemodynamic response to pneumoperitoneum to laparoscopic cholecystectomy under general anaesthesia. METHODOLOGY: 60 patients ASA Physical status I and II, aged between 18 and 50 years of either sex, scheduled for elective laparoscopic cholecy stectomy were randomized in to 2 groups ( group D and S inn a double blind fashion to receive either Dexmedetomidine ( 1microgram/kg in 100ml of 0.9% normal saline or only 0.9%plain normal saline respectively. It is given 30 min prior to induction. Patient vitals like HR, SBP, DBP, MAP were monitored during the study at various time intervals. RESULTS: Following intubation and pneumoperitoneum there significant rise in HR, MAP, SBP, DBP in group S but no significant rise in Group D. CONCLUSION: Dexmedetomid ine given in a dose of 1microgram/kg as a premedication is e ffective in attenuating the hemodynamic responses in laparoscopic surgery

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. 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.

Investigation of efficiency of liquid synbiotics and structure-resonance electric magnetic therapy (SRMT) among patients after cholecystectomy. 90 patients after cholecystectomy have been investigated (CE). Along with general clinical meth-ods of investigation, patients passed US investigation of abdomen, biochemical blood tests, bacteriological test of faeces, investigation of short-chain fatty acids (SCFA) by gas-liquid osteal chromatographic analysis. State of vegetative nervous system passed analysis according to variability of heart rhythm (VHR) by spectral analysis method using "Cardiac technic 4000 AD" cardiac monitor in frame of 24-hr ECG monitoring. Estimation of life quality (LQ) of patients after cholecystectomy has been conducted by "SF-36 Health status survey". Patients have been divided into 3 groups, comparable according to the main clinical and functional indicators. Patients of first group (30 people) passed correction of dysbiosis by liquid synbiotics. Patients of a second group (30 persons) passed complex treatment of SRMT and liquid synbiotics. Control group was composed by 30 patients after cholecystectomy who had been receiving diet therapy. In term of investigation 90% of patients have shown decrease of number and methabolic activity of microflora, change of activity of anaerobic microorganisms. Analysis of variability of heart rhythm have displayed relative prevalence of sympathetic modulation of a rhythm on the background of elevated ergotropic component of the total capacity of a spectrum; estimation of life quality (LQ) has shown that limitation of physical activity is a most considerable contribution to decrease of LQ among patients after cholecystectomy. After a course of liquid synbiotics and SMRT recovery and improvement of intestines and improvement of all indicator of life quality is observed.

We studied the indications for laparoscopic cholecystectomy (LC) and values of preoperative imaging findings in 82 patients who underwent preoperative imaging diagnostic tests (abdominal echogram, abdominal CAT scan, ERCP). We analyzed mainly patients who were considered to be indicated for LC but whose gallbladders could be removed by open laparotomy, or whose gallbladders were removed by open laparotomy but were considered indicated for LC from retrospective study. We found the following results. LC could be easily performed in patients with a history of severe acute cholecystitis if they had no findings of a thickened wall or negative gallbladder signs. Abdominal echogram and CAT scan were the best preoperative imaging tests for determining the gallbladder's state, especially for obstruction of the cystic duct. These results are important today when the operative indications of LC are extremely indefinite because of the accumulation of operative experience and technological improvements. (author)

Laparoscopic cholecystectomy (LC) still leads to significant postoperative nausea and vomiting (PONV) and pain. Our aim was to evaluate the efficacy of dexamethasone or pheniramine hydrogen maleate, either alone or combined, in reducing the stress response and symptoms after LC. Patients were randomly assigned to 1 of 4 groups, each consisting of 20 patients: control, dexamethasone (8 mg/2 mL), pheniramine hydrogen maleate (45.5 mg/2 mL), and the combined group. The drugs were given before anesthesia induction. C-reactive protein levels (CRP) and visual analog scale (VAS) scores were significantly less in the dexamethasone (P = .003) and combined groups (P pheniramine hydrogen maleate (P = .005) significantly reduced PONV. Dexamethasone significantly reduced postoperative pain and the systemic acute-phase response, whereas these effects were only partially attained with pheniramine hydrogen maleate. Both dexamethasone and pheniramine hydrogen maleate significantly reduced PONV. An additive effect seemed to occur if these drugs were used in combination. Copyright © 2013 Elsevier Inc.

Pethidine is a synthetic opioid with local anesthetic properties. Our goal was to evaluate the analgesic efficacy of pethidine for achieving the ultrasound-guided oblique subcostal transversus abdominis plane (OSTAP) block in laparoscopic cholecystectomy. This prospective, double-blind study included 79 patients of physical status I and II according to American Society of Anesthesiologists, scheduled for elective laparoscopic cholecystectomy. The patients were randomly allocated into three groups, depending on the drug used to achieve preoperative bilateral OSTAP block: 1) OSTAP-Placebo (treated with normal saline); 2) OSTAP-Bupivacaine (treated with 0.25% bupivacaine); and 3) OSTAP-Pethidine (treated with 1% pethidine). The efficacy of pethidine in achieving the OSTAP block was analyzed using visual analog scale (VAS), intraoperative opioid dose, opioid consumption in post anesthesia care unit, and opioid consumption in the first 24 postoperative hours. The pain scores assessed by VAS at 0, 2, 4, 6, 12, and 24 hours were significantly lower in OSTAP-Pethidine than in OSTAP-Placebo group (p consumption was significantly lower in OSTAP-Pethidine compared to OSTAP-Placebo group (150 versus 400 mg, p consumption in the first 24 hours (20.4 versus 78 mg, p < 0.001). Comparing VAS assessment between OSTAP-Bupivacaine and OSTAP-Pethidine groups, statistically significant differences were observed only for the immediate postoperative pain assessment (0 hours), where lower values were observed in OSTAP-Pethidine group (p = 0.004). There were no statistically significant differences in the incidence of postoperative nausea and vomiting (p = 0.131) between the groups. The use of 1% pethidine can be an alternative to 0.25% bupivacaine in achieving OSTAP block for laparoscopic cholecystectomy.

The third most common healthcare-associated infection is surgical site infection (SSI), accounting for 14%-16% of infections. These SSIs are associated with high morbidity, numerous deaths, and greater cost. A prospective study was conducted to assess the incidence of SSI in a single university hospital in Croatia. We used the Hospital in Europe Link for Infection Control through Surveillance (HELICS) protocol for surveillance. The SSIs were classified using the standard definition of the National Nosocomial Infections Surveillance (NNIS) system. The overall incidence of SSI was 1.44%. The incidence of infection in the open cholecystectomy group was 6.06%, whereas in the laparoscopic group, it was only 0.60%. The incidence density of in-hospital SSIs per 1,000 post-operative days was 5.76. Patients who underwent a laparoscopic cholecystectomy were significantly younger (53.65±14.65 vs. 64.42±14.17 years; pconcept for the monitoring of SSI, but in the case of cholecystectomy, additional factors such as antibiotic appropriateness, gallbladder entry, empyema of the gallbladder, and obstructive jaundice must be considered.

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.

The Mathematics of Elections and Voting  takes an in-depth look at the mathematics in the context of voting and electoral systems, with focus on simple ballots, complex elections, fairness, approval voting, ties, fair and unfair voting, and manipulation techniques. The exposition opens with a sketch of the mathematics behind the various methods used in conducting elections. The reader is lead to a comprehensive picture of the theoretical background of mathematics and elections through an analysis of Condorcet’s Principle and Arrow’s Theorem of conditions in electoral fairness. Further detailed discussion of various related topics include: methods of manipulating the outcome of an election, amendments, and voting on small committees. In recent years, electoral theory has been introduced into lower-level mathematics courses, as a way to illustrate the role of mathematics in our everyday life.  Few books have studied voting and elections from a more formal mathematical viewpoint.  This text wi...

Reliable prediction of operative duration is essential for improving patient and care team satisfaction, optimizing resource utilization and reducing cost. Current operative scheduling systems are unreliable and contribute to costly over- and underestimation of operative time. We hypothesized that the inclusion of patient-specific factors would improve the accuracy in predicting operative duration. We reviewed all elective laparoscopic cholecystectomies performed at a single institution between 01/2007 and 06/2013. Concurrent procedures were excluded. Univariate analysis evaluated the effect of age, gender, BMI, ASA, laboratory values, smoking, and comorbidities on operative duration. Multivariable linear regression models were constructed using the significant factors (p historical surgeon-specific and procedure-specific operative duration. External validation was done using the ACS-NSQIP database (n = 11,842). A total of 1801 laparoscopic cholecystectomy patients met inclusion criteria. Female sex was associated with reduced operative duration (-7.5 min, p < 0.001 vs. male sex) while increasing BMI (+5.1 min BMI 25-29.9, +6.9 min BMI 30-34.9, +10.4 min BMI 35-39.9, +17.0 min BMI 40 + , all p < 0.05 vs. normal BMI), increasing ASA (+7.4 min ASA III, +38.3 min ASA IV, all p < 0.01 vs. ASA I), and elevated liver function tests (+7.9 min, p < 0.01 vs. normal) were predictive of increased operative duration on univariate analysis. A model was then constructed using these predictive factors. The traditional surgical scheduling system was poorly predictive of actual operative duration (R 2  = 0.001) compared to the patient factors model (R 2  = 0.08). The model remained predictive on external validation (R 2  = 0.14).The addition of surgeon as a variable in the institutional model further improved predictive ability of the model (R 2  = 0.18). The use of routinely available pre-operative patient factors improves the prediction of operative

Nigeria and Democratic Progress by Elections in Africa

Full Text Available Elections do not always advance democratisation, yet they can. We outline a democratisation-by-elections model according to which the opportunities for political change opened up by each electoral round build on previous election-related democratic progress. We focus on Nigeria, interpret the recent executive turnover in light of previous elections, and set the country within the comparative context of Africa’s democratisation. Using a new Africa Leadership Change dataset, we use election-related events to examine the diverse routes that African regimes have taken since 1990. The analysis highlights two major syndromes: democratic stagnation and recession. In a sizeable group, however, the institutionalisation of democracy has been making gradual progress. While there is no predetermined way to advance democracy, the reiteration of elections can be instrumental in such advancement.

Little data exist regarding the recurrence of pancreatitis in pediatric patients with gallstone pancreatitis awaiting cholecystectomy. This study evaluates the recurrence rate of pancreatitis after acute gallstone pancreatitis based on the timing of cholecystectomy in pediatric patients. A retrospective chart review of all patients admitted with gallstone pancreatitis from 2007 to 2015 was performed. Children were divided into the following five groups. Group 1 had surgery during the index admission. Group 2 had surgery within 2 wk of discharge. Group 3 had surgery between 2 and 6 wk postdischarge. Group 4 had surgery 6 wk after discharge, and group 5 patients had no surgery. The recurrence rates of pancreatitis were calculated for all groups. Forty-eight patients with gallstone pancreatitis were identified in this study. The 19 patients in group 1 had no recurrence of their pancreatitis. Of the remaining 29 patients, nine (31%) had recurrence of pancreatitis or required readmission for abdominal pain prior to their cholecystectomy. In group 2, two of the eight patients (25%) had recurrent pancreatitis. In group 3, three of eight patients (37.5%) developed recurrent pancreatitis. In group 4, three of five patients (60%), and in group 5, one of eight. No children in group 5 had demonstrable gallstones at presentation, only sludge in their gallbladder. Cholecystectomy during the index admission is associated with no recurrence or readmission for pancreatitis. Therefore, we recommend that cholecystectomy be performed after resolution of an episode of gallstone pancreatitis during index admission. Copyright © 2017 Elsevier Inc. All rights reserved.

[Malpractice in laparoscopic cholecystectomy. Results of cases recently considered by the Expert Commission].

1999-01-01

The Expert Commission for medical malpractice which is part of the Medical Chamber of Nordrhein received about 60 applications in connection with laparoscopic cholecystectomy; as of August 1998 5 complaints were let off and 11 of them are still being considered. So far 44 complaints have been considered and in 25 of them medical malpractice has been established. The medical malpractice detected laparoscopic cholecystectomy cases were mainly bile duct injuries of which 13 required a biliodigestive anastomosis for reconstruction, four cases required and end-to-end anastomosis and in one case a T-tube drainage was needed. The youngest one of these patients was 21 years old, the oldest one was 61 years old. Four times the bile duct injury was not considered as malpractice, because it could be intraoperatively made out and immediately treated. Trocar injuries were twice a cause for malpractice and once it was not. Each of the following cases was also recognized as a malpractice. One lost gallstone one dislocated Roedersnare, one electric injury, one delayed reintervention and one insufficient information. The following cases were decided as non-malpractice: in two cases a slipped clip, in five cases subhepatical hematoma/abscess, in three cases a secondary bleeding, once a lesion of the splenic capsule and finally a running sore with subsequent incisional hernia. Three courses of treatment with consequence of death also contained mistakes: one electric injury of the bowel, one bile duct lesion and one information rebuke. The bile duct injury is the most considerable risk for laparoscopic cholecystectomy and implies also a high risk for the future health. The experienced surgeon distinguishes himself by the fact that he is right about the situation and converts sooner that later to conventional cholecystectomy if there's any doubt. In open surgery the principle is applied that structures may be only divided when they are clearly identified. The same goes even on a wider

Due to the current economic crisis in Greece, major cutbacks on healthcare costs have been imposed, resulting in a shortage of surgical supplies, including laparoscopic materials. In an attempt to reduce costs, we developed a homemade specimen retrieval bag for laparoscopic cholecystectomy. We used the polyethylene bag containing the catheter of a Redon drainage set. The bag was cut in half and pleated longitudinally; then, the gallbladder was placed in the bag and removed through the umbilicus with a grasping forceps. From September 2011 to June 2012, we used our homemade bag on 85 patients undergoing laparoscopic cholecystectomy. No rupture, accidental opening, or bile leak was observed. The learning curve was found to be five cases. Our homemade specimen retrieval bag seems to be a safe, effective, and easy tool for tissue extraction. Further studies need to be conducted to evaluate its full potential. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

The purpose of this study was to determine the effectiveness of laparoscopic cholecystectomy in children with biliary dyskinesia. Reports of children with an abnormal cholecystokinin (CCK)-stimulated HIDA scan between January 2001 and July 2006 who underwent laparoscopic cholecystectomy were reviewed. Postoperatively, a 23-item Likert scale, symptom questionnaire was administered to parents. Sixty-four children with chronic abdominal pain and no gallstones on ultrasound had an abnormal CCK-HIDA scan. Twenty-three children (median age, 14 years; 16 girls), with mean (SD) ejection fraction of 17% (8), underwent laparoscopic cholecystectomy and were further analyzed. Preoperatively, these children had right upper quadrant/epigastric pain (78%), nausea (52%), vomiting (43%), and generalized abdominal pain (22%) lasting for a median of 3 months (range, 1 month to 2.5 years). Median postoperative follow-up was 2.7 years. Sixteen (70%) parents completed the questionnaire. Of those who responded, 63% indicated that their children had no abdominal pain, 87% had no vomiting, and 69% had no nausea in the month preceding the questionnaire. Overall, 67% of parents indicated that their children's symptoms were completely relieved after cholecystectomy, whereas 7% indicated that the symptoms were not relieved. Laparoscopic cholecystectomy is effective in providing both short-term and long-term improvement of symptoms in children with biliary dyskinesia.

Introduced in 1989, laparoscopic cholecystectomy has rapidly become the treatment of choice for symptomatic gallstones. This study describes the diffusion of laparoscopic cholecystectomy among general surgeons; assesses the importance of various reasons for surgeons adopting the procedure; and examine the influence of surgeon, practice, and health care market characteristics on the timing of adoption. The data were obtained from a survey of a national sample of surgeons. Most surgeons (81%) adopted laparoscopic cholecystectomy by early 1992. More than three fourths of adopters identified the desire to keep up with the state-of-the-art and improved patient outcomes as very or extremely important reasons for adoption. Results of proportional hazards regression analysis indicate that individual surgeons' adoption behavior generally was consistent with expected utility maximization in an uncertain new technological environment. Of particular interest, fee-for-service payment and more competitive practice settings and markets were associated with earlier adoption. These findings suggest that the "technological imperative" and surgeons' perception of the relative clinical and financial advantages of laparoscopic cholecystectomy were important reasons for the rapid diffusion of laparoscopic cholecystectomy. Policies that accelerate current trends toward payment of physicians based on salary or capitation and promote the growth of multispecialty group practice could slow the diffusion of new physician-based product innovations in health care.

Full Text Available ABSTRACT Objective: to evaluate the pulmonary function of women submitted to conventional and single-port laparoscopic cholecystectomy. Methods: forty women with symptomatic cholelithiasis, aged 18 to 70 years, participated in the study. We divided the patients into two groups: 21 patients underwent conventional laparoscopic cholecystectomy, and 19, single-port laparoscopic cholecystectomy. We assessed pulmonary function through forced vital capacity (FVC, forced expiratory volume in the first second (FEV1, and the FEV1/FVC ratio, measured before and 24 hours after the procedure. Results: in both groups, FVC and FEV1 were lower in the postoperative period than those obtained in the preoperative period, with a greater reduction in the group undergoing conventional laparoscopic cholecystectomy. Regarding the FEV1/FVC (% values, there was no statistically significant difference in any of the groups or times analyzed. Conclusion: there was a greater decline in FVC and FEV1 in the postoperative group of patients submitted to conventional laparoscopic cholecystectomy.

Routine administration of antibiotics to patients suffering accidental gallbladder perforation during laparoscopic cholecystectomy is not necessary.

Science.gov (United States)

Guzmán-Valdivia, Gilberto

2008-12-01

Accidental rupture of the gallbladder is an event which occurs in up to 20% of laparoscopic cholecystectomies, mainly in those where dissection is difficult, or during extraction when the gallbladder is withdrawn directly through the laparoscope port. It has been commonly assumed that contamination by bile in the abdominal cavity could be a cause of infection and lead to the formation of a residual abscess or even to surgical wound infection. It is common practice, therefore, for the surgeon to prescribe the application of an antibiotic at the moment when gallbladder perforation occurs. To compare 2 groups of similar patients, to determine whether administration of antibiotics, started during surgery, is actually useful in reducing the risk of residual abscess or infection in the surgical wound. The study considered a total of 166 patients who had suffered accidental perforation of the gallbladder during elective laparoscopic cholecystectomy. This total was divided at random into 2 groups: group A (80 patients) who received a dose of 1 g of Cefotaxime at the moment of gallbladder rupture, followed by 2 more doses at intervals of 8 hours in the immediate postoperative period; and group B (86 patients) who did not receive any antibiotic treatment at all. The dependent variables observed were surgical wound infection and residual abscess: and the control variables were age, sex, length of operation time, intercurrent illnesses, and American Society of Anesthesiologists (ASA) classification. Two patients (2.5%) in group A developed a surgical wound infection, against 3 cases (3.4%) in group B, the result having no statistical significance. No patients developed residual abscess. In a multivariant analysis, the following were identified as independent factors significantly associated with the onset of surgical wound infection (Pgallbladder during laparoscopic cholecystectomy is not necessary.

Full Text Available Pethidine is a synthetic opioid with local anesthetic properties. Our goal was to evaluate the analgesic efficacy of pethidine for achieving the ultrasound-guided oblique subcostal transversus abdominis plane (OSTAP block in laparoscopic cholecystectomy. This prospective, double-blind study included 79 patients of physical status I and II according to American Society of Anesthesiologists, scheduled for elective laparoscopic cholecystectomy. The patients were randomly allocated into three groups, depending on the drug used to achieve preoperative bilateral OSTAP block: 1 OSTAP-Placebo (treated with normal saline; 2 OSTAP-Bupivacaine (treated with 0.25% bupivacaine; and 3 OSTAP-Pethidine (treated with 1% pethidine. The efficacy of pethidine in achieving the OSTAP block was analyzed using visual analog scale (VAS, intraoperative opioid dose, opioid consumption in post anesthesia care unit, and opioid consumption in the first 24 postoperative hours. The pain scores assessed by VAS at 0, 2, 4, 6, 12, and 24 hours were significantly lower in OSTAP-Pethidine than in OSTAP-Placebo group (p < 0.001. The mean intraoperative opioid consumption was significantly lower in OSTAP-Pethidine compared to OSTAP-Placebo group (150 versus 400 mg, p < 0.001, as well as the mean opioid consumption in the first 24 hours (20.4 versus 78 mg, p < 0.001. Comparing VAS assessment between OSTAP-Bupivacaine and OSTAP-Pethidine groups, statistically significant differences were observed only for the immediate postoperative pain assessment (0 hours, where lower values were observed in OSTAP-Pethidine group (p = 0.004. There were no statistically significant differences in the incidence of postoperative nausea and vomiting (p = 0.131 between the groups. The use of 1% pethidine can be an alternative to 0.25% bupivacaine in achieving OSTAP block for laparoscopic cholecystectomy.

Single-incision laparoscopic cholecystectomy (SILC) is a promising alternative to standard multi-incision laparoscopic cholecystectomy (LC). However, generalization of SILC is still hampered by technical difficulties mainly associated with the lack of trocars used for retraction of the gallbladder. We therefore developed a modified method of SILC with the use of needle graspers (SILC-N) for optimal retraction and exposure. In addition to two trocars inserted through a single transumbilical incision, two needle ports were placed on the right subcostal and lateral abdominal wall, through which needle graspers were used for retraction of the gallbladder. Since December, 2009, 12 patients with symptomatic cholelithiasis were treated by SILC-N. SILC-N was successfully performed in all but one patient requiring a conversion to the 4-port LC with a mean operative time of 71.5 (48-107) minutes. None of the patients experienced intraoperative or postoperative complications. The transumbilical incision and pinholes for needle graspers were almost invisible on discharge. Our preliminary results suggest that SILC-N is a simple, safe and feasible technique of cholecystectomy offering similar postoperative recovery and better cosmetic outcome as compared to conventional LC.

An expert recommendation conference was conducted to identify factors associated with adverse events during laparoscopic cholecystectomy (LC) with the goal of deriving expert recommendations for the reduction of biliary and vascular injury. Nineteen hepato-pancreato-biliary (HPB) surgeons from high-volume surgery centers in six countries comprised the Research Institute Against Cancer of the Digestive System (IRCAD) Recommendations Group. Systematic search of PubMed, Cochrane, and Embase was conducted. Using nominal group technique, structured group meetings were held to identify key items for safer LC. Consensus was achieved when 80% of respondents ranked an item as 1 or 2 (Likert scale 1-4). Seventy-one IRCAD HPB course participants assessed the expert recommendations which were compared to responses of 37 general surgery course participants. The IRCAD recommendations were structured in seven statements. The key topics included exposure of the operative field, appropriate use of energy device and establishment of the critical view of safety (CVS), systematic preoperative imaging, cholangiogram and alternative techniques, role of partial and dome-down (fundus-first) cholecystectomy. Highest consensus was achieved on the importance of the CVS as well as dome-down technique and partial cholecystectomy as alternative techniques. The put forward IRCAD recommendations may help to promote safe surgical practice of LC and initiate specific training to avoid adverse events. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Gallbladder Nonvisualization in Cholecystectomy: A Factor for Conversion.

2018-01-01

Many risk factors have been identified in minimally invasive cholecystectomies that lead to higher complications and conversion rates. No study that we encountered looked at nonvisualization of the gallbladder (GB) during surgery as a risk factor. We hypothesized that nonvisualization was associated with an increased risk of complications and could be an early intraoperative identifier of a higher risk procedure. Recognizing this could allow surgeons to be aware of potential risks and to be more likely to convert to open for the safety of the patient. We looked at minimally invasive cholecystectomies performed at our institution from January 2015 through April 2016 and had the performing resident fill out a survey after the surgery. Outcomes were conversion rates, intraoperative complications, and blood loss and were analyzed via Pearson χ 2 test or Mann-Whitney U test. The primary outcome showed a conversion rate of 37% in nonvisualized GBs versus 0% in visualized ( P = .001). Secondary outcomes showed significant differences in GB perforations (74% vs 13%, P = .001), omental vessel bleeding (16% vs. 0%, P = .005), and EBL (46 mL vs 29 mL, P = .001). Intraoperative nonvisualization of the GB after adequate positioning caused significantly increased risk of intraoperative complications and conversion. This knowledge could be useful during intraoperative assessment, to decide whether a case should be continued as a minimally invasive procedure or converted early to help reduce risk to the patient. Further randomized controlled studies should be performed to further demonstrate the value of this assessment.

Why routine intensive care unit admission after elective open infrarenal Abdominal Aortic Aneurysm repair is no longer an evidence based practice.

LENUS (Irish Health Repository)

Ryan, David

2012-01-31

BACKGROUND: Elective open infrarenal Abdominal Aortic Aneurysm (AAA) repair is major surgery performed on high-risk patients. Routine ICU admission postoperatively is the current accepted standard of care. Few of these patients actually require a level of care that cannot be provided just as effectively in a surgical high dependency unit (HDU). Our aim was to determine, \\'can high risk patients that will require ICU admission postoperatively be reliably identified preoperatively?\\'. METHODS: A retrospective analysis of all elective open infrarenal AAA repairs in our institution over a 3-year period was performed. The Estimation of Physiological Ability and Surgical Stress (E-PASS) model was used as our risk stratification tool for predicting post-operative morbidity. Renal function was also considered as a predictor of outcome, independent of the E-PASS. RESULTS: 80% (n = 16) were admitted to ICU. Only 30% (n = 6) of the total study population necessitated intensive care. There were 9 complications in 7 patients in our study. The E-PASS comprehensive risk score (CRS)\\/Surgical stress score (SSS) were found to be significantly associated with the presence of a complication (p = 0.009)\\/(p = 0.032) respectively. Serum creatinine (p = 0.013) was similarly significantly associated with the presence of a complication. CONCLUSIONS: The E-PASS model possessing increasing external validity is an effective risk stratification tool in safely deciding the appropriate level of post-operative care for elective infrarenal AAA repairs.

Full Text Available Marina Yiasemidou, Daniel Glassman, Peter Vasas, Sarit Badiani, Bijendra Patel Barts and the London School of Medicine and Dentistry, Department of Upper GI Surgery, Barts and The Royal London Hospital, London, UK Background: Virtual reality simulators have been gradually introduced into surgical training. One of the enhanced features of the latest virtual simulators is haptic feedback. The usefulness of haptic feedback technology has been a matter of controversy in recent years. Previous studies have assessed the importance of haptic feedback in executing parts of a procedure or basic tasks, such as tissue grasping. The aim of this study was to assess the role of haptic feedback within a structured educational environment, based on the performance of junior surgical trainees after undergoing substantial simulation training. Methods: Novices, whose performance was assessed after several repetitions of a task, were recruited for this study. The performance of senior house officers at the last stage of a validated laparoscopic cholecystectomy curriculum was assessed. Nine senior house officers completed a validated laparoscopic cholecystectomy curriculum on a haptic simulator and nine on a nonhaptic simulator. Performance in terms of mean total time, mean total number of movements, and mean total path length at the last level of the validated curriculum (full procedure of laparoscopic cholecystectomy was compared between the two groups. Results: Haptic feedback significantly reduced the time required to complete the full procedure of laparoscopic cholecystectomy (mean total time for nonhaptic machine 608.83 seconds, mean total time for haptic machine 553.27 seconds; P = 0.019 while maintaining safety standards similar to those of the nonhaptic machine (mean total number of movements: nonhaptic machine 583.74, haptic machine 603.93, P = 0.145, mean total path length: for nonhaptic machine 1207.37 cm, for haptic machine 1262.36 cm, P = 0

It has been a prevailing assumption that cholecystectomy patients by and large follow a pattern of survival similar to that of the normal population. This paper presents a population-based study of the long-term survival after cholecystectomy in order to reassess this assumption. Based on data...... to both hysterectomy patients and a sample of the female population. Adjusting for age and other covariates, patients with psychiatric hospital admissions prior to surgery experienced a threefold risk of dying within 6 years after surgery. Patients with prior somatic admissions and patient with acute...... admissions had a relative risk (RR) of about 1.5. Cholecystectomy patients had a significantly increased mortality when compared to hysterectomy patients, RR = 1.3 (1.1-1.6), and to the population sample.

Transumbilical Laparo-Endoscopic Single Site (LESS) surgery promises improved cosmesis, quick recovery, reduced postoperative pain and shorter length of hospital stay. Since only a simple umbilical incision is used, LESS surgery can be completed with segmental epidural anesthesia. This study describes the evolution of our technique of LESS cholecystectomy from a combination of spinal and epidural anesthesia to thoracic epidural alone and presents our experience with its safety, the observed morbidity, and the reported patient satisfaction. In August 2009, a prospective evaluation of LESS cholecystectomy with regional anesthesia was undertaken. We recruited patients with chronic cholecystitis or symptomatic cholelithasis. Blood loss, operative time, complications, and length of hospital stay were measured. Preoperatively and 14 days postoperatively, outcome and symptom resolution were scored. Fifteen consecutive patients underwent LESS cholecystectomy; first with combined spinal-epidural (CSE), and then with thoracic epidural anesthesia alone. Immediate postoperative pain and discomfort were well tolerated. VAS scores upon admission to PACU were 0.4 (1.7±2.2). At postoperative day 14, the patients scored high values for "Satisfaction", 10 (10±1.0) and "Cosmesis", 10 (9.3±1.5). LESS cholecystectomy with epidural anesthesia can be undertaken safely. Patient satisfaction and cosmesis are particularly prominent amongst our patients. Our experience supports further utilization of epidural anesthesia for selected patients undergoing LESS cholecystectomy.

Nine adult Asiatic black bears (Ursus thibetanus) previously rescued from illegal bile farming in Vietnam were examined via abdominal ultrasound and exploratory laparoscopy for liver and gall bladder pathology. Three bears demonstrated notable gall bladder pathology, and minimally invasive cholecystectomies were performed using an open laparoscopic access approach, standard 10 to 12 mmHg carbon dioxide pneumoperitoneum and a four-port technique. A single bear required insertion of an additional 5 mm port and use of a flexible liver retractor due to the presence of extensive adhesions between the gall bladder and quadrate and left and right medial liver lobes. The cystic duct was dissected free and this and the cystic artery were ligated by means of extracorporeal tied Meltzer knot sutures. The gall bladder was dissected free of the liver by blunt and sharp dissection, aided by 3.8 MHz monopolar radiosurgery. Bears that have had open abdominal cholecystectomies are reported as taking four to six weeks before a return to normal activity postoperatively. In contrast, these bears demonstrated rapid unremarkable healing, and were allowed unrestricted access to outside enclosures to climb trees, swim and interact normally with other bears within seven days of surgery.

The management of patients after uncomplicated elective gastrointestinal operations is frequently left to junior members of the surgical team once they have learnt their seniors' regimens. The use of nasogastric (N/G) tubes, the volume of intravenous (IV) fluid replacement and the reintroduction of oral fluids and solids are topics not generally covered in the surgical textbooks and so are learnt in hospital. A postal survey of all consultant general surgeons in Scotland was conducted to assess the variations in management of patients after cholecystectomy, right haemicolectomy and sigmoid colectomy. A completed questionnaire was received from 111 (81%) of the surgeons circulated. As might be expected, patient management varied widely from surgeon to surgeon, and from unit to unit. There would appear to be a need for prospective studies in this area of patient management. This may indicate that the use of N/G tubes could be further reduced and that oral fluids and solids could be reintroduced sooner after operation with improved patient comfort and reduced hospital stay, yet without detriment to patient care.

Acute gallstone pancreatitis is quite common throughout the globe. Conventionally definitive cholecystectomy has been delayed in index hospital admission. Since the last decade timing of cholecystectomy is gradually shifting towards the earlier phase of disease and currently gallstone pancreatitis is being evaluated as a further indication for laparoscopic cholecystectomy. There is also great concern regarding compliance of patients for definitive surgery due to poverty, ignorance and illiteracy in developing countries. The aim of this study was to assess the feasibility and safety of laparoscopic cholecystectomy as a definitive treatment in patients with mild and resolving gall stone pancreatitis. This was a prospective study from July 2009 to June 2012. Patients were diagnosed by clinical examination, biochemical tests, ultrasonography and contrast enhanced CT. Patients with mild form of the disease (Ranson Score ≤3) and who showed clinical improvement were offered laparoscopic cholecystectomy in index hospital admission. Those who were unfit for surgery were referred for endoscopic sphincterotomy. Common bile duct stones were excluded preoperatively. A total of 38 patients were admitted with acute gallstone pancreatitis in the study period. The mean age of patients was 46.3 years with male to female ratio of 11/27. 22 (57.8%) patients were selected for laparoscopic cholecystectomy and procedure was completed successfully. Ten (26.3%) patients were referred for ERCP and endoscopic sphincterotomy and 11 (28.9%) were managed by conservative treatment and went without any definitive treatment. Mean duration of time from onset of symptoms and laparoscopic cholecystectomy was 7 days (range 4-10). Mean duration of operative time was 45 minutes and hospital stay was 7 days. There was no operative mortality. No major intra-operative or post-operative complication was recorded. two patients (9%) had minor complications. Laparoscopic cholecystectomy can be safely

Although international opportunities are the hallmark of nursing education at a large private university, the meaning of participating in such clinical nursing electives has not been described. The purpose of this phenomenological study of nurses was to examine the personal and professional meaning of participating in international clinical nursing electives during their undergraduate nursing studies. Audiotaped interviews were conducted with 20 former nursing students who had had this opportunity. "Opening our hearts and minds" was described by the study's participants, with the following themes: increasing understanding of other cultures and peoples, increasing understanding of global sociopolitical and health issues, increasing the commitment to make a difference, experiencing personal and professional growth, contributing to professional development in the host country, making interpersonal connexions, and developing cultural competence. This study makes an important contribution to the documentation of the meaning of participating in international nursing clinical experiences. Data are being used for long-term curricular planning in the development and refinement of future international clinical nursing electives and to provide outcomes data for professional accreditation. There are broader implications for the movement beyond individual cultural competence to increasing global consciousness and the improvement of global health care.

Minimally invasive techniques are used more and more frequently. Since conventional laparoscopic approach has been the gold standard, surgeons in their effort to further reduce the invasiveness of conventional laparoscopic cholecystectomy have adopted Single Incision approach. The widespread adoption of robotics has led to the inevitable hybridization of robotic technology with laparoendoscopic single-site surgery (LESS). As a result, employment of the da Vinci surgical system may allow greater surgical maneuverability, improving ergonomics. A review of the English literature was conducted to evaluate all robotic single port cholecystectomy performed till today. Demographic data, operative parameters, postoperative outcomes and materials used for the operation were collected and assessed. A total of 12 studies, including 501 patients were analyzed. Demographics and clinical characteristics of the patients was heterogeneous, but in most studies a mean BMI port cholecystectomy is a safe and feasible alternative to conventional multiport laparoscopic or manual robotic approach. However, current data do not suggest a superiority of robotic SILC over other established methods.

The aim of this study was to determine the financial costs to institution on patients waiting for gall bladder disease surgery and suggest measures to reduce them. This multi-centre prospective descriptive survey was performed on all patients who underwent an elective cholecystectomy by three consultants at secondary care hospitals in Pakistan between Jan 2010 to Jan 2012. Data was collected on demographics, the duration of mean waiting time, specific indications and nature of disease for including the patients in the waiting list, details of emergency re-admissions while awaiting surgery, investigations done, treatment given and expenditures incurred on them during these episodes. A total of 185 patients underwent elective open cholecystectomy. The indications for listing the patients for surgery were biliary colic in 128 patients (69%), acute cholecystitis in 43 patients (23%), obstructive jaundice in 8 patients (4.5%) and acute pancreatitis in 6 patients (3.2%). 146 (78.9%) and 39 (21.1%) of patients were listed as outdoor electives and indoor emergencies respectively. Of the 185 patients, 54 patients (29.2%) were re-admitted. Financial costs in Pakistani rupees per episode of readmission were 23050 per episode in total and total money spent on all readmissions was Rs. 17,05,700/-. Financial costs on health care institutions due to readmissions in patients waiting for gall bladder disease surgery are high. Identifying patients at risk for these readmissions and offering them early laparoscopic cholecystectomy is very important.

Background The value of robotics in general surgery may be for advanced minimally invasive procedures. Unlike other specialties, formal fellowship training opportunities for robotic general surgery are few. As a result, most surgeons currently develop robotic skills in practice. Our goal was to determine whether robotic cholecystectomy is a safe and effective bridge to advanced robotics in general surgery. Methods Before performing advanced robotic procedures, 2 surgeons completed the Intuitive Surgical da Vinci training course and agreed to work together on all procedures. Clinical surgery began with da Vinci cholecystectomy with a plan to begin advanced procedures after at least 10 cholecystectomies. We performed a retrospective review of our pilot series of robotic cholecystectomies and compared them with contemporaneous laparoscopic controls. The primary outcome was safety, and the secondary outcome was learning curve. Results There were 16 procedures in the robotics arm and 20 in the laparoscopic arm. Two complications (da Vinci port-site hernia, transient elevation of liver enzymes) occurred in the robotic arm, whereas only 1 laparoscopic patient (slow to awaken from anesthetic) experienced a complication. None was significant. The mean time required to perform robotic cholecystectomy was significantly longer than laparoscopic surgery (91 v. 41 min, p robotic procedures (14 v. 11 min, p = 0.015). We observed a trend showing longer mean anesthesia time for robotic procedures (23 v. 15 min). Regarding learning curve, the mean operative time needed for the first 3 robotic procedures was longer than for the last 3 (101 v. 80 min); however, this difference was not significant. Since this experience, the team has confidently gone on to perform robotic biliary, pancreatic, gastresophageal, intestinal and colorectal operations. Conclusion Robotic cholecystectomy can be performed reliably; however, owing to the significant increase in operating room resources, it

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

Gallbladder specimens are routinely sent for histopathological examination after cholecystectomy in order to rule out the presence of unexpected pathological findings. To establish the overall incidence of unexpected pathological findings in patients who underwent laparoscopic cholecystectomy for symptomatic gallbladder disease and determine whether the macroscopic appearance of the gallbladder in ultrasound examination could be a valid method for identifying patients with gallbladder malignancy. A retrospective study was conducted between 2013 and 2015. All histological reports (n = 1131) after cholecystectomy were searched for unexpected pathological findings. In cases where unexpected pathological findings were identified the additional analysis of preoperative abdominal ultrasound examination (USG) was done to determine the usefulness of USG in diagnosis of gallbladder malignancy. Of the 1131 patients included in the study, 356 (31.47%) were male and 774 (68.43%) were female. Unexpected pathological findings were present in 21 cases. The overall incidence of unexpected pathological findings was 1.86%. Only in 5 patients were suspicious appearances of gallbladder observed in preoperative ultrasound examination. In 16 patients there was no suspicion of malignancy. The positive predictive value of USG was 0.238. The incidence of unexpected pathological findings after laparoscopic cholecystectomy was 1.86%. Ultrasonography has low positive predictive value for identifying patients with malignant findings in a gallbladder specimen.

The 2016 presidential election season and subsequent political events have had physical and emotional impacts on youth. We collected qualitative insights from 14 to 24 year olds across the US related to these events over time. Open-ended probes were sent via text message at three time points before and after the 2016 presidential election. The majority of youth reported emotional stress during all three time points, and female participants were significantly more likely to experience emotional responses. White participants were more likely to report negative symptoms than their peers both pre-election and at 4-months post-election. While preliminary, the results indicate that feelings of stress, anxiety, and fear have persisted in the months following the election, particularly for young women. Additional research is needed to examine the long-term effects of political events on the emotional and physical health of youth.

Aim of this study is the evaluation of the impact of a multimedia CD (MCD) on preoperative anxiety and postoperative recovery of patients undergoing elective laparoscopic cholecystectomy (LC). Sixty consecutive candidates for elective LC were randomly assigned to four groups. Group A included 15 patients preoperatively informed regarding LC through the MCD presented by Registered Nurse (RN). Patients in group B (n = 15) were informed through a leaflet. Patients in group C (n = 15) were informed verbally from a RN. Finally, the control Group D included 15 patients informed conventionally by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, and C. Preoperative assessment of knowledge about LC was performed after each informative session through a questionnaire. Evaluation of preoperative anxiety was conducted using APAIS scale. Postoperative pain and nausea scores were measured using an NRS scale, 16 hours after the patient had returned to the ward. Statistical processing of the results (single linear regression) showed that patients in groups A, B, and C achieved a higher knowledge score, less preoperative anxiety score and less postoperative pain and nausea, compared to Group D. In multiple regression analysis, group A had a higher knowledge score compared to the four groups (p Informative sessions using MCD is an effective means of improving patient's preoperative knowledge, especially in day-surgery cases, like LC.

Concern about allogeneic blood product cost and complications has prompted interest in blood conservation techniques. Intraoperative autotransfusion (IAT) is currently not used routinely by vascular surgeons in open elective infrareanl abdominal aortic aneurysm (AAA) repair. The objective of this study is to review our experience with IAT and its impact on blood transfusion. We retrospectively reviewed the medical records of consecutive patients treated electively over a 4-year period and compared 2 strategy related to IAT, routine use IAT (rIAT) versus on-demand IAT (oIAT). Outcomes measured were number of units of allogeneic red blood cells and autologous red blood cells transfused intraoperatively and postoperatively, preoperative, postoperative, and discharge hemoglobin levels; postoperative infections; length of postoperative intensive care stay; and length of hospital stay. T-independent and Fisher exact test were used. A total of 212 patients were included, 38 (18%) in the rIAT and 174 (82%) in the oIAT. Groups were similar except for an inferior creatinine and a superior mean aneurysm diameter for the rIAT group. Patients in the rIAT group had a lower rate of transfusion (26% vs 54%, P = .002) and a lower mean number of blood unit transfused (0.8 vs 1.8, P = .048). These findings were still more significant for AAA larger than 60 mm (18% rIAT vs 62% oIAT, P = .0001). Postoperative hemoglobin was superior in the rIAT group (107 vs 101 g/L, P = .01). Mean postoperative intensive care length of stay was shorter for the rIAT group (1.1 vs 1.8 days, P = .01). No difference was noted for infection, mortality, or hospital length of stay. The rIAT reduced the exposure to allogeneic blood products by more than 50%, in particular for patients with AAA larger than 60 mm. These results support the use of rIAT for open elective infrarenal AAA repair.

Full Text Available A 79-year-old man, with history of recent laparoscopic cholecystectomy, came to our attention for persistent hiccup, dysphonia, and dysphagia. Noninvasive imaging studies showed a nodular lesion in the right hepatic lobe with transdiaphragmatic infiltration and increased tracer uptake on positron emission tomography. Suspecting a malignant lesion and given the difficulty of performing a percutaneous transthoracic biopsy, the patient underwent surgery. Histological analysis of surgical specimen showed biliary gallstones surrounded by exudative inflammation, resulting from gallbladder rupture and gallstones spillage as a complication of the previous surgical intervention. This case highlights the importance of considering such rare complication after laparoscopic cholecystectomy.

To describe and evaluate a new cholecystectomy technique combining classical dissection with currently available mini-instrumentation (3 and 5 mm) and gallbladder removal through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. We performed 106 procedures, including 99 in a prospective study between January 2008 and July 2010. Cholecystectomy was performed with the described technique in 99 of 106 eligible patients (22 males and 77 females, mean age 45.8 years (range 18-77); median BMI 26.4 kg/m2 (range 22-36)). Forty-eight patients had at least one gallstone larger than 10 mm. There were no postoperative gastric complications and recovery was always rapid. This procedure is technically feasible, safe and reproducible. The results are good, with minimal abdominal wall trauma. Normal physical activity can be resumed rapidly with no risk of incisional hernia.

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

Directory of Open Access Journals (Sweden)

Bouwense Stefan A

2012-11-01

Full Text Available Abstract 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.

Full Text Available Traditional management of gallstone pancreatitis (GP has been to perform cholecystectomy during the same hospital admission after resolution. However, when GP develops in the immediate postoperative period from a major colorectal operation, cholecystectomy may be fraught with difficulty due to the inflammatory response that occurs. Thus, delaying cholecystectomy until the inflammatory response subsides may be worthwhile, and it maximizes the chances of completing the cholecystectomy laparoscopically. We have described our management of 2 patients with GP occurring after colorectal operations, which required proximal diverting ileostomy. In both cases, we deferred management of GP with either endoscopic retrograde cholangiopancreatography (ERCP or medical conservative measures during the acute attack and performed laparoscopic cholecystectomy during ostomy reversal surgery utilizing the existing ostomy takedown site for port placement. Both patients tolerated this management well.

Acute cholecystitis is a common diagnosis. However, the heterogeneity of presentation makes it difficult to standardize management. Although surgery is the mainstay of treatment, critically ill patients have been managed via percutaneous cholecystostomy. However, the role of percutaneous cholecystostomy in the management of such patients has not been clearly established. This systematic review will compare the outcomes of critically ill patients with acute cholecystitis managed with percutaneous cholecystostomy to those of similar patients managed with cholecystectomy. Systematic searches will be conducted across relevant health databases including the Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL), MEDLINE, Embase, and Scopus using the following keywords: (acute cholecystitis OR severe cholecystitis OR cholecystitis) AND (cholecystectomy OR laparoscopic cholecystectomy OR open cholecystectomy) AND (Cholecystostomy OR percutaneous cholecystectomy OR gallbladder drain OR gallbladder tube OR transhepatic gallbladder drain OR transhepatic gallbladder tube OR cholecystostomy tube). The reference lists of eligible articles will be hand searched. Articles from 2000-2014 will be identified using the key terms "acute cholecystitis, cholecystectomy, and percutaneous cholecystostomy". Studies including both interventions will be included. Relevant data will be extracted from eligible studies using a specially designed data extraction sheet. The Newcastle-Ottawa scale will be used to assess the quality of non-randomized studies. Central tendencies will be reported in terms of means and standard deviations where necessary, and risk ratios will be calculated where possible. All calculations will be performed with a 95 % confidence interval. Furthermore, the Fisher's exact test will be used for the calculation of significance, which will be set at p < 0.05.

Full Text Available 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.

The concept of reducing the number of transabdominal access ports has been criticized for violating basic tenets of traditional multiport laparoscopy. Potential benefits of reduced port surgery may include decreased pain, improved cosmesis, less hernia formation, and fewer wound complications. However, technical challenges associated with these access methods have not been adequately addressed by advancement in instrumentations. We describe our initial experience with the NovaTract™ Laparoscopic Dynamic Retractor. A retrospective review of all patients who underwent two-port laparoscopic cholecystectomy between 2013 and 2014 using the NovaTract retractor was performed. The patients were equally divided into three groups (Group A, B, C) based on the order of case performed. Eighteen consecutive patients underwent successful two-port laparoscopic cholecystectomy for symptomatic cholelithiasis. Mean age was 39.9 years and mean body mass index was 28.1 kg/m(2) (range 21-39.4). Overall mean operative time was 65 minutes (range 42-105), with Group A of 70 minutes, Group B of 65 minutes, and Group C of 58 minutes (P = .58). All cases were completed laparoscopically using the retraction system, without a need for additional ports or open conversion. No intra- or postoperative complications were seen. All patients were discharged on the same day of surgery. No mortality found in this series. The NovaTract laparoscopic dynamic retractor is safe and easy to use, which is reflected by acceptable operative time for a laparoscopic cholecystectomy using only two ports. The system allows surgical approach to mimic the conventional laparoscopic techniques, while eliminating or reducing the number of retraction ports.

To compare the recovery profile in terms of time of extubation, eye opening, orientation and mobility and frequency of Postoperative Nausea and Vomiting (PONV) between propofol and isoflurane based anesthesia in patients undergoing laparoscopic cholecystectomy with prophylactic antiemetic. After informed consent, a total of 60 ASA I-II patients scheduled for laparoscopic cholecystectomy were divided in two equal groups I and P. Anesthesia in all patients were induced by Nalbuphine 0.15 mg/kg, Midazolam 0.03 mg/kg, Propofol 1.5 mg/kg and Rocuronium 0.6 mg/kg. Anesthesia was maintained with Isoflurane in group I and propofol infusion in group P, while ventilation was maintained with 50% N/sub 2/O/sub 2/ mixture in both the groups. All patients were given antiemetic prophylaxis. Hemodynamics were recorded throughout anesthesia and recovery period. At the end of surgery, times of extubation, eye opening, orientation (by modified Aldrete score) and mobility (recovery profile) were assessed. PONV was observed and recorded immediately after extubation, during early postoperative period (0-4 hours) and late period (4-24 hours). Antiemetic requirements were also recorded for the same periods in both the groups. Propofol provided faster recovery (extubation and eye opening times) and orientation in immediate postoperative period with statistically significant differences between the groups (p<0.0001). Recovery characteristics were comparably lower in group I. More patients achieved full points (8) on modified Aldrete score at different time until 30 minutes in group P. Postoperative nausea and vomiting in early and late periods were significantly reduced in group P. Moreover, requirement of rescue antiemetic doses were significantly lower in group P in 24 hours (p<0.0001). In this series, recovery was much faster with earlier gain of orientation with propofol anesthesia compared to isoflurane in the early recovery periods. Propofol is likely to be a better choice of

Sepsis from dropped clips at laparoscopic cholecystectomy

Hussain, Sarwat

2001-01-01

We report seven patients in whom five dropped surgical clips and two gallstones were visualized in the peritoneal cavity, on radiological studies. In two, subphrenic abscesses and empyemas developed as a result of dropped clips into the peritoneal cavity during or following laparoscopic cholecystectomy. In one of these two, a clip was removed surgically from the site of an abscess. In two other patients dropped gallstones, and in three, dropped clips led to no complications. These were seen incidentally on studies done for other indications. Abdominal abscess secondary to dropped gallstones is a well-recognized complication of laparoscopic cholecystectomy (LC). We conclude that even though dropped surgical clips usually do not cause problems, they should be considered as a risk additional to other well-known causes of post-LC abdominal sepsis

Although numerous epidemiological studies on cholecystectomy have been conducted worldwide, only a few have considered the effect of socioeconomic inequalities on cholecystectomy outcomes. Specifically, few studies have focused on the low-income population (LIP). A nationwide prospective study based on the Taiwan National Health Insurance dataset was conducted during 2003-2012. The International Classification of ICD-9-CM procedure codes 51.2 and 51.21-51.24 were identified as the inclusion criteria for cholecystectomy. Temporal trends were analyzed using a joinpoint regression, and the hierarchical linear modeling (HLM) method was used as an analytical strategy to evaluate the group-level and individual-level factors. Interactions between age, gender and SES were also tested in HLM model. Analyses were conducted on 225,558 patients. The incidence rates were 167.81 (95% CI: 159.78-175.83) per 100,000 individuals per year for the LIP and 123.24 (95% CI: 116.37-130.12) per 100,000 individuals per year for the general population (GP). After cholecystectomy, LIP patients showed higher rates of 30-day mortality, in-hospital complications, and readmission for complications, but a lower rate of routine discharge than GP patients. The hospital costs and length of stay for LIP patients were higher than those for GP patients. The multilevel analysis using HLM revealed that adverse socioeconomic status significantly negatively affects the outcomes of patients undergoing cholecystectomy. Additionally, male sex, advanced age, and high Charlson Comorbidity Index (CCI) scores were associated with higher rates of in-hospital complications and 30-day mortality. We also observed that the 30-day mortality rates for patients who underwent cholecystectomy in regional hospitals and district hospitals were significantly higher than those of patients receiving care in a medical center. Patients with a disadvantaged finance status appeared to be more vulnerable to cholecystectomy surgery

Cholelithiasis is the second cause of hospital admissions in Chile. To study the prevalence of symptomatic gallstone disease and opportunity of cholecystectomy in La Florida, Santiago and among Mapuche Indians in Huapi Island. In the period 2000-2001, we contacted to 71% (1127 subjects) and to 61% (145 subjects) patients of La Florida and Huapi Island, respectively, that had previously participated in an epidemiological study on cholelithiasis in 1993. We defined symptomatic gallstone patients as those with a history of biliary colic. Each patient was subjected to gallbladder ultrasound. In 1993, 30-35% of gallstone patients were symptomatic (approximately 70% women). During the lapse 1993-2001, only 50% of subjects from La Florida and 25% of patients from Huapi Island were cholecystectomized (p Mapuche Indians from Huapi, cholecystectomy was indicated in 2001. After five months of the indication, only one of these subjects had been operated. Laparoscopic cholecystectomy represented 40% of all cholecystectomies performed in the National Health Service Hospitals. This study demonstrates an unacceptable high prevalence of symptomatic gallstone patients remaining non-operated in both the urban and rural communities. This reciprocally correlates with the high frequency of emergency cholecystectomies and the high incidence of gallbladder cancer among Chileans. This study contrasts negatively with the situation of Scotland, where 73.5% of cholecystectomies were laparoscopic in 1998-1999. To reach Scotland standards, the Chilean Public Health System should increase the number of cholecystectomies from 27,000 in 2001 to 57,510

Acute calculous cholecystitis represents one of the most common complications of cholelithiasis. While laparoscopic cholecystectomy is the standard treatment in mild and moderate forms, the need for antibiotic therapy after surgery remains undefined. The aim of the randomised controlled Cholecystectomy Antibiotic Randomised Trial (CHART) is therefore to assess if there are benefits in the use of postoperative antibiotics in patients with mild or moderate acute cholecystitis in whom a laparoscopic cholecystectomy is performed. A single-centre, double-blind, randomised trial. After screening for eligibility and informed consent, 300 patients admitted for acute calculus cholecystitis will be randomised into two groups of treatment, either receiving amoxicillin/clavulanic acid or placebo for 5 consecutive days. Postoperative evaluation will take place during the first 30 days. Postoperative infectious complications are the primary end point. Secondary end points are length of hospital stay, readmissions, need of reintervention (percutaneous or surgical reinterventions) and overall mortality. The results of this trial will provide strong evidence to either support or abandon the use of antibiotics after surgery, impacting directly in the incidence of adverse events associated with the use of antibiotics, the emergence of bacterial resistance and treatment costs. This study and informed consent sheets have been approved by the Research Projects Evaluating Committee (CEPI) of Hospital Italiano de Buenos Aires (protocol N° 2111). The results of the trial will be reported in a peer-reviewed publication. NCT02057679. Published by the BMJ Publishing Group Limited.

2016-12-01

Using claims data from the Helsana Group, a large Swiss health insurance provider, we examined the association between statin use and the risk of cholecystectomy in a case-control analysis. We identified 2,200 cholecystectomy cases between 2013 and 2014 and matched 4 controls to each case on age, sex, index date and canton. We categorized statin users into current or past users (last prescription ≤ 180 or > 180 days before the index date, respectively) and classified medication use by duration based on number of prescriptions before the index date. We applied conditional logistic regression analyses to calculate odds ratios (ORs) with 95% confidence intervals (CIs) and adjusted the analyses for history of cardiovascular diseases and for use of estrogens, fibrates and other lipid-lowering agents. The adjusted OR (aOR) for cholecystectomy was 0.85 (95% CI: 0.74, 0.99) for current statin users compared to non-users. Long-term current statin use (5-19 prescriptions) was associated with a reduced OR (aOR 0.77, 95% CI: 0.65, 0.92). However, neither short-term current use nor past statin use affected the risk of cholecystectomy. The study supports the previously raised hypothesis that long-term statin use reduces the risk of cholecystectomy.

Laparoscopic cholecystectomy (LC) is usually performed under general anesthesia. Recently, laparoscopic cholecystectomy under regional anesthesia has become popular, but this creates a serious risk of thromboembolism because of pneumoperitoneum, anesthesia technique, operative positioning, and patient-specific risk factors. This randomized controlled trial compares the effects of two different anesthesia techniques in laparoscopic cholecystectomy on coagulation and fibrinolysis. This randomized prospective study included 60 low-risk patients with deep vein thrombosis (DVT) who underwent elective LC without thrombo-emboli prophylaxis. The patients were randomly divided into two groups according to the anesthesia technique: the general anesthesia (group 1, n = 30) and spinal epidural anesthesia (group 2, n = 30) groups. Measurement of the prothrombin time (PT), thrombin time (TT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), and blood levels of D-dimer (DD) and fibrinogen (F) were recorded preoperatively (pre), at the first hour (post 1) and 24 h (post 24) after the surgery. These results were compared both between and within the groups. The mean age was 51.5 ±16.7 years (range: 19-79 years). Pneumoperitoneum time was similar between group 1 (33.8 ±7.8) and group 2 (34.8 ±10.4). The TT levels significantly declined postoperatively in both groups. The levels of PT, aPTT, INR, D-dimer and fibrinogen dramatically increased postoperatively in both groups. While there was not any DVT, there was a significant decline in TT. There was a dramatic rise in the PT, INR, D-dimer, fibrin degradation products (FDP), and fibrinogen following LC. This may be attributed to the effects of pneumoperitoneum and anesthesia techniques on portal vein flow.

Full Text Available ObjectiveTo investigate whether operative time of laparoscopic cholecystectomy impacts the carbonyl hemoglobin (COHb concentration in peripheral blood. MethodsForty patients with gallstones and indications for laparoscopic cholecystectomy were enrolled in the study. Peripheral venous blood samples were collected at the beginning and end of the operative procedure. COHb concentration was measured by UV spectroscopy. The significance of changes in COHb concentration in relation to time of the operative procedure (rounded to the nearest minute was assessed by statistical correlation coefficient test. ResultsThe laparoscopic procedure was completed in 38 cases, and two patients required conversion to laparotomy. The content of COHb in peripheral venous blood had significantly increased during the laparoscopic operation (operation beginning: 11.07%±1.18% vs. operation end: 1.44%±0.26%, P＜0.05. The change was positively correlated with operation time (r=0.85. ConclusionCarbon monoxide produced during the laparoscopic cholecystectomy procedure can lead to an increase in peripheral venous blood COHb. The longer the operation lasts, the greater the increase in COHb.

The need to integrate aspects of functional, psychosocial and cosmetic impairment into medical care is increasingly accepted among the physicians and the patients. For these reasons, single-port robotic surgery emerges as the most advanced approach using the technology. In this study, authors used a new robotic dissector with monopolar electrocautery feature in order to determine the device's safety and efficacy. Between January 2015 and February 2016, 10 out of 11 consecutive cholecystectomies were included in the study. There was no significant differences in port placement and docking time between two groups (p=0.382, p=0.789). The time spent by surgeon was significantly shorter in group 2 (p=0.005). Using robotic dissector with monopolar cautery significantly shortened the console time. This new instrument (Maryland monopolar dissector) provides more feasible and faster dissection of the Calot's triangle, supporting further the advantages of robotic single-site cholecystectomy.

2017-06-01

Full Text Available Background: Port site infection (PSI is an infrequent surgical site infection that complicates laparoscopic surgery but has a considerable influence in the overall outcome of laparoscopic cholecystectomy. The aim of this study was to evaluate factors that influence PSI after laparoscopic cholecystectomies and to analyze which of these factors can be modified to avoid PSI in a trail to achieve maximum laparoscopic advantages. Methods: A prospective descriptive qualitative study conducted on patients who underwent laparoscopic cholecystectomies. Swabs were taken for culture & sensitivity in all patients who developed PSI. Exploration under general anaesthesia, for patients, had deep surgical site infections and wound debridement was done, excisional biopsies had been taken for histopathological studies, and tissue samples for polymerase chain reaction for detection of mycobacterium tuberculosis was done. All patients were followed up for six months postoperatively. Factors as gender, site of infected port, type of microorganism, acute versus chronic cholecystitis, type of infection (superficial or deep infection and intraoperative spillage of stones, bile or pus were analyzed in our sample. Results: Port site infection rate was recorded in 40/889 procedures (4.5%, higher rates were observed in male patients 8/89 (8.9%, in acute cholecystitis 13/125 (10.4%, when spillage of bile, stones or pus occurred 24/80 (30%, and at epigastric port 32/40 (80%. Most of the PSI were superficial infections 77.5% with non-specific microorganism 34/40 (85%. Conclusion: There is a significant association of port site infection with spillage of bile, stones, or pus, with the port of gallbladder extraction and with acute cholecystitis. Especial consideration should be taken in chronic deep surgical site infection as mycobacterium tuberculosis could be the cause. Most of the PSIs are superficial and more common in males.

Routine use of intraoperative cholangiography during laparoscopic cholecystectomy is still widely advocated and standard in many departments; however, it is controversial. We have developed a new diagnostic strategy for the detection of bile duct stones. The concept is based on an ultrasound examination and on screening for the presence of six risk indicators of choledocholithiasis. A total of 120 patients undergoing laparoscopic cholecystectomy were prospectively screened for the presence of these six risk indicators: history of jaundice, history of pancreatitis, hyperbilirubinemia, hyperamylasemia, dilated bile duct, and unclear ultrasound findings. The sensitivity of ultrasound and intraoperative cholangiography in diagnosing bile duct stones was also evaluated. For the detection of bile duct stones, the sensitivity was 77% for ultrasound and 100% for intraoperative cholangiography. Twenty percent of all patients had at least one risk indicator. The presence of a risk indicator correlated significantly with the presence of choledocholithiasis (P concept, we would have avoided 80% of intraoperative cholangiographies without missing a stone in the bile duct. This study lends further support to the view that routine use of intraoperative cholangiography is not necessary.

Gallbladder perforation often occurs during laparoscopic cholecystectomy. The frequency and causes of gallbladder perforation as well as the relevant clinical background factors were investigated in 110 patients undergoing laparoscopic cholecystectomy. We also evaluated intraperitoneal contamination by bacteria and gallstones at the time of gallbladder perforation and investigated whether perforation caused early or late postoperative complications. Intraoperative gallbladder perforation occurred in 29 of the 110 patients (26.3%). It was caused by injury with an electric knife during dissection of the gallbladder bed, injury during gallbladder retraction with grasping forceps, injury during gallbladder extraction from the abdomen, and slippage of cystic duct clips (potentially causing bile and stone spillage). Perforation was more frequent in patients with positive bile cultures and in those with pigment stones (p gallbladder perforation is sometimes unavoidable during laparoscopic cholecystectomy, the risk of severe complications appears to be minimized by early closure of perforation, retrieval of as many of the spilled stones as possible, and intraperitoneal lavage.

Full Text Available ObjectiveTo investigate whether blood lipid control can delay the progression of asymptomatic gallstones and reduce the risk of cholecystectomy in patients with gallstones and hyperlipidemia, as well as the influence of hyperlipidemia on postoperative pain after cholecystectomy. MethodsA total of 153 patients with asymptomatic gallstones and hyperlipidemia who underwent physical examination from February 2013 to February 2015 were enrolled and randomly divided into experimental group with 72 patients and control group with 81 patients. The patients in the experimental group were given blood lipid control via diet, exercise, and drugs, and according to fasting triglyceride (TG and total cholesterol (TC after 3 months, these patients were further divided into normal blood lipid group with 47 patients and abnormal blood lipid group with 25 patients. All the patients were followed up for 2 years with an interval of 3 months. The surgical indications for laparoscopic cholecystectomy were persistent pain in the gallbladder or more than 3 times of gallbladder discomfort within the past one month. A subgroup analysis was performed based on the number and size of gallstones to evaluate the risk of cholecystectomy. A numerical pain scale was used to assess the improvement in pain during hospitalization and at 3 and 6 months after surgery. The t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between three groups, and the Bonferroni test was used for further comparison between any two groups. The chi-square test was used for comparison of categorical data between groups. ResultsThe normal blood lipid group had a significantly lower rate of cholecystectomy than the abnormal blood lipid group and the control group (23.4% vs 68.8%/70.4%, χ2=2772, P＜0.01. The patients in the normal blood lipid group had moderate pain during hospitalization, while those in the abnormal blood lipid

Nigerian Election Management Bodies and their Associated Election Challenges

Full Text Available The paper examined the challenges that confront Election Management Bodies (EMBs in conducting free and fair elections in Nigeria. It aligns with the position of extant literature on the subject that elections in Nigeria have been anything but free and fair, and argues that all the EMBs that have so far conducted elections in Nigeria are complicit in perpetrating electoral malpractices. In other words, though there are external factors that undermine the conduct of free, fair and credible elections in Nigeria, EMBs in Nigeria also present themselves as willing tools in the hands of politicians to compromise the integrity of the electoral process. The number of litigations and level of both international and local denunciations that attend every election in Nigeria underscores the magnitude of electoral malfeasance inherent in the elections conducted by successive EMBs in Nigeria. The paper analysed the major challenges that inhibit the conduct of free and fair elections in Nigeria and proffered solutions to them. Relying heavily on the documentary methods of data collection, the paper concludes that until all these challenges confronting EMBs in Nigeria in the conduct of free and fair elections are comprehensively addressed, credible elections will continue to be a mirage in the country.

To analyze the outcomes of single-port laparoscopic cholecystectomy. Early and long-term postoperative period has been analyzed in 240 patients who underwent laparoscopic cholecystectomy (LCE) including 120 cases of single-port technique and 120 cases of four-port technique. Both groups were compared in surgical time, pain syndrome severity (visual analog scale), need for analgesics, postoperative complications, hospital-stay, daily activity recovery and return to physical work, patients' satisfaction of surgical results and their aesthetic effect. It was revealed that single-port LCE is associated with lower severity of postoperative pain, quick recovery of daily activity and return to physical work, high satisfaction of surgical results and their aesthetic effect compared with four-port LCE. Disadvantages of single-port LCE include longer duration of surgery, high incidence of postoperative umbilical hernia. However hernia was predominantly observed during the period of surgical technique development. Further studies to standardize, evaluate the safety and benefits of single-port LCE are necessary.

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

Previous studies have indicated a correlation between indication for cholecystectomy and long-term gastrointestinal quality-of-life (QoL). The aim of the present study was to compare QoL in a post-cholecystectomy cohort with the background population and with historical controls. A post-cholecystectomy study group (on average 4 years after cholecystectomy) was compared with a control group from the background population using the Gastrointestinal Quality-of-Life Index (GIQLI). EQ-5D scores were compared with expected scores derived from recent historical data. The post-cholecystectomy study group (N = 451) had better QoL measured by the EQ-5D compared with historical controls (p < 0.001), similar total GIQLI scores as the control group (N = 390), but scored worse on the GIQLI gastrointestinal symptoms subscale score (p < 0.001). The results include an item-by-item breakdown of the GIQLI questionnaire where the scores for diarrhea, bowel urgency, bloating, regurgitation, abdominal pain, flatus, fullness, nausea, uncontrolled stools, belching, heartburn, restricted eating, and bowel frequency were found to be significantly lower (i.e. worse) in the post-cholecystectomy cohort than in the control group. The opposite was true for relationships, endurance, sexual life, physical strength, feeling fit, not being frustrated by illness, and being able to carry out leisure activities, i.e. items related to general performance and well-being. In this study, QoL after cholecystectomy was good, but there was an increased prevalence of gastrointestinal symptoms compared to the background population.

Many surgeons attempting Laparo-Endoscopic Single Site (LESS) cholecystectomy have found the operation difficult, which is inconsistent with our experience. This article is an attempt to promote a standardized approach that we feel surgeons with laparoscopic skills can perform safely and efficiently. This is a four-trocar approach consistent with the four incisions utilized in conventional laparoscopic cholecystectomy. After administration of general anesthesia, marcaine is injected at the umbilicus and a 12-mm vertical incision is made through the already existing anatomical scar of the umbilicus. A single four-trocar port is inserted. A 5-mm deflectable-tip laparoscope is placed through the trocar at the 8 o'clock position, a bariatric length rigid grasper is inserted through the trocar at the 4 o'clock position (to grasp the fundus), and a rigid bent grasper is placed through the 10-mm port (to grasp the infundibulum). This arrangement of the instruments promotes minimal internal and external instrument clashing with simultaneous optimization of the operative view. This orientation allows retraction of the gallbladder in a cephalad and lateral direction, development of a window between the gallbladder and the liver which promotes the "critical view" of the cystic duct and artery, and provides triangulation with excellent visualization of the operative field. The operation is concluded with diaphragmatic irrigation of marcaine solution to minimize postoperative pain. Standardization of LESS cholecystectomy will speed adoption, reduce intraoperative complications, and improve the efficiency and safety of the approach.

Routine use of intraoperative cholangiography during laparoscopic cholecystectomy is still widely advocated and standard in many departments, however, this is discussed controversially. We have developed a new diagnostic strategy to detect bile duct stones. The concept is based on an ultrasound examination and on a screening for the presence of six risk indicators of choledocholithiasis. 120 consecutive patients undergoing laparoscopic cholecystectomy were prospectively screened for the presence of six risk indicators of choledocholithiasis: history of jaundice; history of pancreatitis; hyperbilirubinemia; hyperamylasemia; dilated bile duct; unclear ultrasound findings. The sensitivity of ultrasound and of intraoperative cholangiography in diagnosing bile duct stones was also evaluated. For the detection of bile duct stones, the sensitivity was 77% for ultrasound and 100% for intraoperative cholangiography. 20% of all patients had at least one risk indicator. The presence of a risk indicator correlated significantly with the presence of choledocholithiasis (p concept, we would have avoided 80% of intraoperative cholangiographies without missing a stone in the bile duct. This study lends further support to the view that the routine use of intraoperative cholangiography in patients undergoing laparoscopic cholecystectomy is not necessary.

Full Text Available Abstract 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

Cholecystectomy in cirrhotic patients – how safe is it?

Directory of Open Access Journals (Sweden)

Petrişor Banu

2017-05-01

Full Text Available Liver cirrhosis is a major health problem worldwide with a prevalence that varies greatly from one geographical area to another. Besides the risk factors common to the general population to develop gallstone disease such as advanced age, female sex or positive family history of gallstones, in patients with liver cirrhosis there are additional risk factors that contribute to the occurrence of gallstones. They are more frequent in patients with a longer duration of the disease and in Child B and C stages. Gallstones disease occurs three times more frequently in patients with liver cirrhosis than in noncirrhotic patients. Surgery is required if symptoms or complications related to the presence of gallstones occur and a thorough preoperative evaluation and optimization of patient’s condition is necessary prior to surgery. The procedure of choice in these situations is laparoscopic cholecystectomy. The technique has some particularities resulting from local anatomical changes and conversion to open technique remains low and morbidity and mortality rates are within acceptable limits.

Standardized short courses in laparoscopic cholecystectomy aim to teach laparoscopic skills to surgical trainees, although end-of-course assessments of performance remain subjective. The current study aims to objectively assess psychomotor skills acquisition of trainees attending laparoscopic cholecystectomy courses. Thirty-seven junior surgical trainees had their laparoscopic skills assessed before and after attending 1 of 3 separate 2-day courses (A, B, and C), all with identical format. Assessments were comprised of a standardized simulated laparoscopic task, with performance measured using a valid electromagnetic hand-motion tracking device. Overall, trainees made significant improvements in path length (P=.006), number of movements (Ppsychomotor skills on courses. In addition to providing participants with an insight into their skills, these data can be used to demonstrate course efficacy.

Many studies have attempted to determine the "best" anaesthetic technique for neurosurgical procedures in patients without intracranial hypertension. So far, no study comparing intravenous (IA) with volatile-based neuroanaesthesia (VA) has been able to demonstrate major outcome differences nor a superiority of one of the two strategies in patients undergoing elective supratentorial neurosurgery. Therefore, current practice varies and includes the use of either volatile or intravenous anaesthetics in addition to narcotics. Actually the choice of the anaesthesiological strategy depends only on the anaesthetists' preferences or institutional policies. This trial, named NeuroMorfeo, aims to assess the equivalence between volatile and intravenous anaesthetics for neurosurgical procedures. NeuroMorfeo is a multicenter, randomized, open label, controlled trial, based on an equivalence design. Patients aged between 18 and 75 years, scheduled for elective craniotomy for supratentorial lesion without signs of intracranial hypertension, in good physical state (ASA I-III) and Glasgow Coma Scale (GCS) equal to 15, are randomly assigned to one of three anaesthesiological strategies (two VA arms, sevoflurane + fentanyl or sevoflurane + remifentanil, and one IA, propofol + remifentanil). The equivalence between intravenous and volatile-based neuroanaesthesia will be evaluated by comparing the intervals required to reach, after anaesthesia discontinuation, a modified Aldrete score > or = 9 (primary end-point). Two statistical comparisons have been planned: 1) sevoflurane + fentanyl vs. propofol + remifentanil; 2) sevoflurane + remifentanil vs. propofol + remifentanil. Secondary end-points include: an assessment of neurovegetative stress based on (a) measurement of urinary catecholamines and plasma and urinary cortisol and (b) estimate of sympathetic/parasympathetic balance by power spectrum analyses of electrocardiographic tracings recorded during anaesthesia; intraoperative

Full Text Available This article examines the tools, approaches, collaboration, and findings of the Web Archives for Historical Research Group around the capture and analysis of about 4 million tweets during the 2015 Canadian Federal Election. We hope that national libraries and other heritage institutions will find our model useful as they consider how to capture, preserve, and analyze ongoing events using Twitter. While Twitter is not a representative sample of broader society - Pew research shows in their study of US users that it skews young, college-educated, and affluent (above $50,000 household income – Twitter still represents an exponential increase in the amount of information generated, retained, and preserved from 'everyday' people. Therefore, when historians study the 2015 federal election, Twitter will be a prime source.On August 3, 2015, the team initiated both a Search API and Stream API collection with twarc, a tool developed by Ed Summers, using the hashtag #elxn42. The hashtag referred to the election being Canada's 42nd general federal election (hence 'election 42' or elxn42. Data collection ceased on November 5, 2015, the day after Justin Trudeau was sworn in as the 42nd Prime Minister of Canada. We collected for a total of 102 days, 13 hours and 50 minutes. To analyze the data set, we took advantage of a number of command line tools, utilities that are available within twarc, twarc-report, and jq. In accordance with the Twitter Developer Agreement & Policy, and after ethical deliberations discussed below, we made the tweet IDs and other derivative data available in a data repository. This allows other people to use our dataset, cite our dataset, and enhance their own research projects by drawing on #elxn42 tweets. Our analytics included: breaking tweet text down by day to track change over time; client analysis, allowing us to see how the scale of mobile devices affected medium interactions; URL analysis, comparing both to Archive

Full Text Available 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.

Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml -1 mixed with 0.5 ml of fentanyl 50 μg ml -1 . Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patient was reviewed 2 days postoperatively in ward. The thoracic spinal anesthetia was performed easily in the patient. Some discomfort which was readily treated with 1mg midazolam and 20 mg ketamine intravenously. There was no neurological deficit and hemodynamic parameters were in normal range intra and post-operatively and recovery was uneventful. We used a narrow gauze (26G) spinal needle which minimized the trauma to the patient and the chances of PDPH, which was more if 16 or 18G epidural needle had been used and could have increased further if there have been accidental dura puncture. Also using spinal anesthesia was economical although it should be done cautiously as we are giving spinal anesthesia above the level of termination of spinal cord.

Recent reports indicate that laparoscopic cholecystectomy in pregnancy is safe. The aim of this study was to evaluate whether delays in definitive treatment of symptomatic cholelithiasis increase morbidity. We reviewed the records of 16 women who underwent laparoscopic cholecystectomy during pregnancy between 1992 and 1999. Mean age was 24 +/- 5 years (mean +/- standard error). Symptom onset was during the first trimester in nine patients, second trimester in six patients, and third trimester in one patient. Patients had abdominal pain (93%), nausea (93%), emesis (80%), and fever (66%) for a median of 45 days (range 1-195 days) before cholecystectomy. Nine of 11 women who underwent cholecystectomy more than 5 weeks after onset of symptoms experienced recurrent attacks necessitating 15 hospital admissions and four emergency room visits. Moreover four women who developed symptoms in the first and second trimesters but whose operations were delayed to the third trimester had 11 hospital admissions and four emergency room visits; three of those four (75%) women developed premature contractions necessitating tocolytics. Cholecystectomy was completed laparoscopically in 14 women. There was no hospital infant or maternal mortality or morbidity. We recommend prompt laparoscopic cholecystectomy in pregnant women with symptomatic biliary disease because it is safe and it reduces hospital admissions and frequency of premature labor.

Cholecystectomy and Diagnosis-Related Groups (DRGs): patient classification and hospital reimbursement in 11 European countries.

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. 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. 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. 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.

Two-port cholecystectomy maintains safety and feasibility in benign gallbladder diseases: a comparative study.

In an effort to overcome the limitations of single-port laparoscopic cholecystectomy (LC) while preserving the cosmetic benefits of reduced ports cholecystectomy, we have developed a 2-port LC that allows for the full, unrestricted use of 4 laparoscopic instruments. We retrospectively analyzed data of patients who had undergone either 4-port LC or 2-port LC for benign gallbladder diseases between March 2007 and March 2013. Two incisions of 2-port LC were composed of an umbilical incision as the manner of single-port laparoscopic surgery and a 5-mm epigastric incision. These two incisions were utilized for comfortable bimanual manipulation under the liver-elevated vision provided by a liver retractor. During the study period, 766 patients underwent LC; 263 (34.3%) started with 4-port LC, and 503 (65.7%) started with 2-port LC. Of patients started with 2-port LC, 486 patients (96.6%) was ended up with 2-port without open conversion or addition of port(s). The two groups had similar operative time, open conversion rate, incidence of complications, analgesic requirement, and length of postoperative hospital stay. Multivariate analyses revealed that the independent factors related to prolonged operative time (≥ 90 th percentile) in 2-port LC were the presence of cholecystitis (odds ratio [OR] 2.412, 95% CI 1.246-4.668, p = 0.009) and admission through the emergency department (OR 2.132, 95% CI 1.135-4.004, p = 0.019). This study suggests that 2-port LC for benign gallbladder diseases is as safe and feasible as 4-port LC when it is performed by surgeons trained in conventional laparoscopic techniques.

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. 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 endoscope 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. 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. 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.

The aim of this study was to investigate whether propofol-based anesthesia adding low-concentration desflurane is feasible for laparoscopic cholecystectomy. Fifty-two patients undergoing laparoscopic cholecystectomy were enrolled in the prospective, randomized, clinical trial. Induction of anesthesia was achieved in all patients with fentanyl 2 μg/kg, lidocaine 1 mg/kg, propofol 2 mg/kg, and rocuronium 0.8 mg/kg to facilitate tracheal intubation and to initiate propofol target-controlled infusion (TCI to effect site concentration (Ce: 4 μg/mL with infusion rate 400 mL/h. The patients were then allocated into either propofol TCI based (group P or propofol TCI adding low-concentration desflurane (group PD for maintenance of anesthesia. The peri-anesthesia hemodynamic responses to stimuli were measured. The perioperative psychomotor test included p-deletion test, minus calculation, orientation, and alert/sedation scales. Group PD showed stable hemodynamic responses at CO2 inflation, initial 15 minutes of operation, and recovery from general anesthesia as compared with group P. There is no significant difference between the groups in operation time and anesthesia time, perioperative psychomotor functional tests, postoperative vomiting, and pain score. Based on our findings, the anesthetic technique combination propofol and desflurane for the maintenance of general anesthesia for laparoscopic cholecystectomy provided more stable hemodynamic responses than propofol alone. The combined regimen is recommended for patients undergoing laparoscopic cholecystectomy.

Sickle cell disease is a public health problem in Africa. The aim of this prospective study was to evaluate per and post-operative complications of laparoscopic cholecystectomy in sickle cell children in Senegal. from January 1999 to December 2006, an anesthetic protocol was applied to 39 sickle cell children undergoing a cholecystectomy. Among them, 20 experienced laparoscopic cholecystectomy. All these 20 patients had previously suffered from sickle cell visceral complications and were classified as ASA II (11 cases) and as ASA III (9 cases). Blood transfusion program aimed at sustaining haemoglobin level between 10 and 12 g/dl was implemented. The preoperative monitoring and anesthesia management were the same for these patients. During perioperative period, the prevention of pain, hypovolemia, hypothermia and acidosis was achieved. The mean insufflation duration of laparoscopy was 23 min (17-60 min), the mean surgery duration was 55 min (40-110 min), and the mean anesthesia duration was 78 min (88-135 min). Postoperative complications occurred in 9 patients: acute chest syndrome (n=2), postoperative hemolysis (n=5), vaso-occlusive crisis (n=2). Laparoscopic cholecystectomy can be carried out in sickle cell children affected with gallstones, provided that general anaesthetic rules were respected. An appropriate pre-, per- and postoperative anaesthesia is mandatory to reduce postoperative complications in children with sickle cell disease. Searching for early diagnosis of gallstones before occurrence of visceral complications should allow further optimal laparoscopic surgery.

Full Text Available Duodenal injury following laparoscopic cholecystectomy is rare complications with catastrophic sequelae. Most injuries are attributed to thermal burns with electrocautery following adhesiolysis and have a delayed presentation requiring surgical intervention. We present a case of a 47-year-old gentleman operated on for laparoscopic cholecystectomy with a bilious drain postoperatively; for which an ERC was done showing choledocholithiasis with cystic duct stump blow-out and a drain in the duodenum suggestive of an iatrogenic duodenal injury. He was managed conservatively like a duodenal fistula and recovered without undergoing any intervention.

Full Text Available 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.

Full Text Available This study aimed to elucidate the effects of cholecystectomy on the risk of colorectal cancer (CRC by conducting a meta-analysis of 10 cohort studies.The eligible cohort studies were selected by searching the PubMed and EMBASE databases from their origination to June 30, 2016, as well as by consulting the reference lists of the selected articles. Two authors individually collected the data from the 10 papers. When the data showed marked heterogeneity, we used a random-effects model to estimate the overall pooled risk; otherwise, a fixed effects model was employed.The final analysis included ten cohort studies. According to the Newcastle-Ottawa Scale (NOS, nine papers were considered high quality. After the data of these 9 studies were combined, an increased risk of CRC was found among the individuals who had undergone cholecystectomy (risk ratio (RR 1.22; 95% confidence interval (CI 1.08-1.38. In addition, we also found a promising increased risk for colon cancer (CC (RR 1.30, 95% CI 1.07-1.58, but no relationship between cholecystectomy and rectum cancer (RC (RR 1.09; 95% CI 0.89-1.34 was observed. Additionally, in the sub-group analysis of the tumor location in the colon, a positive risk for ascending colon cancer (ACC was found (RR 1.18, 95% CI 1.11-1.26. After combining the ACC, transverse colon cancer (TCC, sigmoid colon cancer (SCC and descending colon cancer (DCC patients, we found a positive relationship with cholecystectomy (RR 1.18, 95% CI 1.11-1.26. Furthermore, after combining the ACC and DCC patients, we also found a positive relationship with cholecystectomy (RR 1.28; 95% CI 1.11-1.26 in the sub-group analysis. In an additional sub-group analysis of patients from Western countries, there was a positive relationship between cholecystectomy and the risk of CRC (RR 1.20; 95% CI 1.05-1.36. Furthermore, a positive relationship between female gender and CRC was also found (RR 1.17; 95% CI 1.03-1.34. However, there was no relationship

Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. Currently, it is not possible to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids fusing minilaparoscopy and transluminal endoscopic surgery. This report presents a prospective clinical series of 25 patients who underwent transvaginal hybrid cholecystectomy for cholelithiasis. The study comprised a clinical series of 25 consecutive nonrandomized women who underwent a fusion transvaginal NOTES and minilaparoscopy procedure with two trocars for cholelithiasis: one 5-mm umbilical trocar and one 3-mm trocar in the upper left quadrant. The study had no control group. The scheduled surgical intervention was performed for all 25 women. No intraoperative complications occurred. One patient had mild hematuria that resolved in less than 12 h, but no other complications occurred during an average follow-up period of 140 days. Of the 25 women, 20 were discharged in 24 h, and 5 were discharged less than 12 h after the procedure. Hybrid transvaginal cholecystectomy, combining NOTES and minilaparoscopy, is a good surgical model for minimally invasive surgery. It can be performed in surgical settings where laparoscopy is practiced regularly using the instruments normally used for endoscopy and laparoscopic surgery. Due to the reproducibility of the intervention and the ease of vaginal closure, hybrid transvaginal cholecystectomy will permit further development of NOTES in the future.

Retrieval of Surgical Clip from Common Bile Duct by Endoscopic Retrograde Cholangiopancreatography: A Rare Complication of Laparoscopic Cholecystectomy

Full Text Available Laparoscopic cholecystectomy has become the standard procedure for the surgical management of symptomatic cholelithiasis. Laparoscopic cholecystectomy is generally considered a safe procedure although a few complications such as major bleeding, wound infection, bile leakage, biliary and bowel injury are well known. We are reporting a case of a thirty-seven year old male who presented with abdominal pain, three weeks after laparoscopic cholecystectomy. Abdominal ultrasound revealed a filling defect in common bile duct with deranged liver function tests. With an impression of choledocholithiasis, his endoscopic retrograde cholangiopancreatography (ERCP was done which revealed a surgical clip impacted in the ampulla. The surgical clip was retrieved successfully by ERCP. Intraductal clip migration is a rarely encountered complication after laparoscopic cholecystectomy. Appropriate management requires timely identification and retrieval during ERCP.

Introduction Advanced (pT2/T3) incidental gallbladder cancer is often deemed unresectable after restaging. This study assesses the impact of the primary operation, tumour characteristics and timing of management on re-resection. Methods The records of 60 consecutive referrals for incidental gallbladder cancer in a single tertiary centre from 2003 to 2011 were reviewed retrospectively. Decision on re-resection of incidental gallbladder cancer was based on delayed interval restaging at three months following cholecystectomy. Demographics, index cholecystectomy data, primary pathology, CA19–9 tumour marker levels at referral and time from cholecystectomy to referral as well as from referral to restaging were analysed. Results Thirty-seven patients with pT2 and twelve patients with pT3 incidental gallbladder cancer were candidates for radical re-resection. Following interval restaging, 24 patients (49%) underwent radical resection and 25 (51%) were deemed inoperable. The inoperable group had significantly more patients with positive resection margins at cholecystectomy (p=0.002), significantly higher median CA19–9 levels at referral (p=0.018) and were referred significantly earlier (p=0.004) than the patients who had resectable tumours. On multivariate analysis, urgent referral (p=0.036) and incomplete cholecystectomy (p=0.048) were associated significantly with inoperable disease following restaging. Conclusions In patients with incidental, potentially resectable, pT2/T3 gallbladder cancer, inappropriate index cholecystectomy may have a significant impact on tumour dissemination. Early referral of breached tumours is not associated with resectability. PMID:25723690

Full Text Available Introduction. Early laparoscopic cholecystectomy is usually associated with reduced hospital stay, sick leave, and health care expenditures. Early diagnosis and treatment of acute cholecystitis reduce both mortality and morbidity and the accurate diagnosis requires specific diagnostic criteria of clinical data and imaging studies. Objectives. To compare early versus delayed laparoscopic cholecystectomy regarding the operative outcome and patient satisfaction. Patients and Methods. Patients with acute cholecystitis were divided into two groups, early (A and delayed (B cholecystectomy. Diagnosis of acute cholecystitis was confirmed by clinical examination, laboratory data, and ultrasound study. The primary end point was operative and postoperative outcome and the secondary was patient’s satisfaction. Results. The number of readmissions in delayed treatment group B was three times in 10% of patients, twice in 23.3%, and once in 66.7% while the number of readmissions was once only in patients in group A and the mean total hospital stays were higher in group B than in group A. The overall patient’s satisfaction was 92.66±6.8 in group A compared with 75.34±12.85 in group B. Conclusion. Early laparoscopic cholecystectomy resulted in significant reduction in length of hospital stay and accepted rate of operative complications and conversion rates when compared with delayed techniques.

A potentially serious complication of laparoscopic cholecystectomy is the inadvertent dissemination of unsuspected gallbladder carcinoma. There are increasing reports of seeding of tumor at the trocar sites following laparoscopic cholecystectomy in patients with unexpected or inapparent gallbladder carcinoma. Although the mechanism of the abdominal wall recurrence is still unclear, laparoscopic handling of the tumor, perforation of the gallbladder, and extraction of the specimen without an endobag may be risk factors for the spreading of malignant cells. The Authors report the case of late development of umbilical metastasis after laparoscopic cholecystectomy; the presence of an incisional hernia and the finding of a stone in subcutaneous tissue demonstrate the diffusion of tumor cells into subcutaneous tissue during the extraction of gallbladder. The patient underwent an excision of the metastases. She is disease free two years after surgical treatment.

Guzzetti Stefano

2009-04-01

Full Text Available Abstract Background Many studies have attempted to determine the "best" anaesthetic technique for neurosurgical procedures in patients without intracranial hypertension. So far, no study comparing intravenous (IA with volatile-based neuroanaesthesia (VA has been able to demonstrate major outcome differences nor a superiority of one of the two strategies in patients undergoing elective supratentorial neurosurgery. Therefore, current practice varies and includes the use of either volatile or intravenous anaesthetics in addition to narcotics. Actually the choice of the anaestesiological strategy depends only on the anaesthetists' preferences or institutional policies. This trial, named NeuroMorfeo, aims to assess the equivalence between volatile and intravenous anaesthetics for neurosurgical procedures. Methods/Design NeuroMorfeo is a multicenter, randomized, open label, controlled trial, based on an equivalence design. Patients aged between 18 and 75 years, scheduled for elective craniotomy for supratentorial lesion without signs of intracranial hypertension, in good physical state (ASA I-III and Glasgow Coma Scale (GCS equal to 15, are randomly assigned to one of three anaesthesiological strategies (two VA arms, sevoflurane + fentanyl or sevoflurane + remifentanil, and one IA, propofol + remifentanil. The equivalence between intravenous and volatile-based neuroanaesthesia will be evaluated by comparing the intervals required to reach, after anaesthesia discontinuation, a modified Aldrete score ≥ 9 (primary end-point. Two statistical comparisons have been planned: 1 sevoflurane + fentanyl vs. propofol + remifentanil; 2 sevoflurane + remifentanil vs. propofol + remifentanil. Secondary end-points include: an assessment of neurovegetative stress based on (a measurement of urinary catecholamines and plasma and urinary cortisol and (b estimate of sympathetic/parasympathetic balance by power spectrum analyses of electrocardiographic tracings recorded

2017-01-01

Full Text Available The recent parliamentary elections which took place in The Slovak Republic in March 2016 opened for many national and international commentators the bottled of demons from the past history of Slovakia. For the first time a Far right extremist political party entered into parliament and held seats there. They gained more than some standard political parties and also were not dubbed as the “black” horse of this election. As they were not measured by public opinion. The main purpose of this article is to analyze the fundamental purpose of voters that had elected this political party and on the other hand the main reason that has opened the parliamentary door to such a political entity that was not visible in the previous electoral periods or played any important role in the independence of Slovak republic. Our main assumption will be that which is taken from the media analysis before the parliamentary election and public opinion research. Our main variable from the external environment will be the migration refugee crisis and the rhetoric of political parties acting at national level. We can assume that this was one of the main reason for the entry of this political party within others which were “hidden” or covered by this crisis and were not mediatized in the media.

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)(pfibromyalgia pain significantly increased and all thresholds significantly decreased at 1week and 1month (1-way ANOVA, pFibromyalgia pain and thresholds returned to preoperative values at 3months, then pain significantly decreased and thresholds significantly increased at 6 and 12months (pfibromyalgia 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 (pfibromyalgia symptoms and that laparoscopic cholecystectomy produces only a transitory worsening of these symptoms, largely compensated by the long-term improvement/desensitization due to gallbladder removal.

Bile duct injuries from laparoscopic cholecystectomy remain a significant source of morbidity and are often the result of intraoperative errors in perception, judgment, and decision-making. This qualitative study aimed to define and characterize higher-order cognitive competencies required to safely perform a laparoscopic cholecystectomy. Hierarchical and cognitive task analyses for establishing a critical view of safety during laparoscopic cholecystectomy were performed using qualitative methods to map the thoughts and practices that characterize expert performance. Experts with more than 5 years of experience, and who have performed at least 100 laparoscopic cholecystectomies, participated in semi-structured interviews and field observations. Verbal data were transcribed verbatim, supplemented with content from published literature, coded, thematically analyzed using grounded-theory by 2 independent reviewers, and synthesized into a list of items. A conceptual framework was created based on 10 interviews with experts, 9 procedures, and 18 literary sources. Experts included 6 minimally invasive surgeons, 2 hepato-pancreatico-biliary surgeons, and 2 acute care general surgeons (median years in practice, 11 [range 8 to 14]). One hundred eight cognitive elements (35 [32%] related to situation awareness, 47 [44%] involving decision-making, and 26 [24%] action-oriented subtasks) and 75 potential errors were identified and categorized into 6 general themes and 14 procedural tasks. Of the 75 potential errors, root causes were mapped to errors in situation awareness (24 [32%]), decision-making (49 [65%]), or either one (61 [81%]). This study defines the competencies that are essential to establishing a critical view of safety and avoiding bile duct injuries during laparoscopic cholecystectomy. This framework may serve as the basis for instructional design, assessment tools, and quality-control metrics to prevent injuries and promote a culture of patient safety. Copyright

Health care providers are increasingly focused on cost containment. One potential target for cost containment is in-hospital management of acute cholecystitis. Ensuring cholecystectomy within 24 hours for cholecystitis could mitigate costs associated with longer hospitalizations. We sought to determine the cost consequences of delaying operative management. The Nationwide Inpatient Sample (2003-2011) was queried for adult patients (≥16 years) who underwent laparoscopic cholecystectomy for a primary diagnosis of acute cholecystitis. Patients who underwent open procedures or endoscopic retrograde cholangiopancreatography were excluded. Generalized linear models (GLMs) were used to analyze costs for each day's delay in surgery. Multivariable analyses adjusted for patient demographics, hospital descriptors, Charlson comorbidity index, mortality, and length of stay. We analyzed 191,032 records. Approximately 65% of the patients underwent surgery within 24 hours of admission. The average cost of care for surgery on the admission day was $11,087. Costs disproportionately increased by 22% on the second hospital day ($13,526), by 37% on the third day ($15,243), by 52% on the fourth day ($16,822), by 64% on the fifth day ($18,196), by 81% on the sixth day ($20,125), and by 100% on the seventh day ($22,250) when compared with the cost of care for procedures performed within 24 hours of admission. Subset analysis of patients discharged 24 hours or earlier from the time of surgery demonstrated similar trends. After controlling for patient- and hospital-related factors, we noted significant costs associated with each day's delay in operative management. Cost containment practices for acute cholecystitis justify consideration of same-day or next-day surgery where the diagnosis is straightforward. Economic and value-based analysis, level III.

There is conflicting evidence for the use of warmed, humidified carbon dioxide (CO2) for creating pneumoperitoneum during laparoscopic cholecystectomy. Few studies have reported less post-operative pain and analgesic requirement when warmed CO2 was used. This systematic review and meta-analysis aims to analyse the literature on the use of warmed CO2 in comparison to standard temperature CO2 during laparoscopic cholecystectomy. Systematic review and meta-analysis carried out in line with the PRISMA guidelines. Primary outcomes of interest were post-operative pain at 6 h, day 1 and day 2 following laparoscopic cholecystectomy. Secondary outcomes were analgesic usage and drop in intra-operative core body temperature. Standard Mean Difference (SMD) was calculated for continuous variables. Six randomised controlled trials (RCTs) met the inclusion criteria (n = 369). There was no significant difference in post-operative pain at 6 h [3 RCTs; SMD = -0.66 (-1.33, 0.02) (Z = 1.89) (P = 0.06)], day 1 [4 RCTs; SMD = -0.51 (-1.47, 0.44) (Z = 1.05) (P = 0.29)] and day 2 [2 RCTs; SMD = -0.96 (-2.30, 0.37) (Z = 1.42) (P = 0.16)] between the warmed CO2 and standard CO2 group. There was no difference in analgesic usage between the two groups, but pooled analysis was not possible. Two RCTs reported significant drop in intra-operative core body temperature, but there were no adverse events related to this. This review showed no difference in post-operative pain and analgesic requirements between the warmed and standard CO2 insufflation during laparoscopic cholecystectomy. Currently there is not enough high quality evidence to suggest routine usage of warmed CO2 for creating pneumoperitoneum during laparoscopic cholecystectomy.

By means of a matched-pair analysis comparing data obtained from laparoscopic cholecystectomy (LC) and robot-assisted laparoscopic cholecystectomy (RAC), the value of both methods as well as the advantages and disadvantages of both approaches were elucidated. The consideration was carried out by evaluation of postoperative surgical results, a cost analysis and a subjective survey of the patients using a questionnaire. Thus, from the 35 consecutive RAC, 35 (parallel) retrospectively matched pairs were established. Postoperative surgical results did not show any significant differences between LC and RAC. In the individual assessment by each patient, there were also no significant differences; however, there was a tendency towards the assessment of the RAC to be slightly worse. A striking difference was found with respect to the cost analysis at the time of surgery. The RAC operation alone is significantly more expensive compared to LC with respect to maintenance and acquisition costs. In addition, RAC can at present not be completely reimbursed under the current German diagnosis-related system. The postulated advantages of RAC comprise mainly the precise preparation within narrow confinements and the favorable ergonomic handling for the surgeon. The basic prerequisites are control of the costs and a reasonable reflection in the current reimbursement system.

Full Text Available BACKGROUND Laparoscopic cholecystectomy is now the gold standard procedure and with over 5,00,000 procedures being done annually, laparoscopic cholecystectomy assumes a great significance in general surgical specialty. This study aims to study the effects of carbon dioxide pneumoperitoneum on the coagulation system of patients undergoing laparoscopic cholecystectomy and make the surgeon aware of the detrimental effects. MATERIALS AND METHODS A prospective clinical observational study of 50 patients selected by systematic sampling method from January 2015 to September 2015 at our institution was conducted to determine the results of changes in coagulation profile of patients undergoing laparoscopic cholecystectomy using carbon dioxide pneumoperitoneum. RESULTS The mean prothrombin time of the patients before surgery is 11.83 seconds. The standard deviation was 1.008 and standard error of mean was 0.143. The mean of prothrombin time 6 hours after surgery was 11.7 seconds. The standard deviation was 0.898 and the standard error of mean being 0.127. The difference in the mean between the two groups was 0.130. The p-value was 0.0109 (<0.05. Hence, the value was statistically extremely significant. The values for D-dimer were analysed. The mean value of D-dimer before surgery is 129.78. The standard deviation was 21.01 and standard error of mean was at 2.97. In the D-dimer values after surgery, mean was calculated to be 350.22 with the standard deviation at 73.21 and standard error of mean at 10.35. CONCLUSION Our study concluded that there is activation of both coagulation and fibrinolytic systems post laparoscopic cholecystectomy.

During laparoscopic cholecystectomy, perforation of the gallbladder can occurs in extraction of the gallbladder. The fate of such lost gallstones, which can lead to the formation of an abscess, an abdominal wall mass, or a persistent sinus, has not been studied adequately. Herein we report the case of a persistent sinus of the abdominal wall after an emergent laparoscopic cholecystectomy in an 82-year-old woman with gangrenous cholecystitis and perforation of the friable wall in association with an empyema of the gallbladder. The culture of the obtained pus was positive for Escherichia coli. After a small leak of dirty fluid from the wound of the epigastric port site of 4 months' duration, surgical exploration under local anesthesia revealed that the sinus was caused by spilled gallstones impacting into the abdominal wall between the posterior sheath and left rectus abdominalis muscle. The removal of the stones resulted in complete healing. Long-term complications after laparoscopic cholecystectomy involving the abdominal wall are rare but important possible consequences that could be avoided.

Full Text Available BACKGROUND With the enormous advancement in the field of laparoscopic cholecystectomy, postoperative pain has substantially reduced as compared to open procedures. However, postoperative pain is still the most frequent complaint, which can hamper recovery, mandate inpatient admission and thereby increase the cost of such care. Preemptive analgesia attenuates sensitisation of pain before surgery so as to reduce postoperative hyperalgesia and allodynia. Pregabalin is a structural analog of γ-aminobutyric acid, which shows analgesic, anticonvulsant, and anxiolytic effects. The aim of the present study was to evaluate the effectiveness of preemptive oral pregabalin on postoperative pain and opioid consumption in patients undergoing laparoscopic cholecystectomy. MATERIALS AND METHODS Eighty adult patients of ASA I and II undergoing laparoscopic cholecystectomy were randomly divided into two groups to receive either pregabalin 150 mg capsule or a matching placebo (vitamin B complex capsule 1 hour before surgery. Anaesthesia technique was standardised in both the groups. Postoperative pain was assessed at 0, 1, 2, 3, 6, 9, 12, 18 and 24 hours period postoperatively by a 10 cm visual analogue scale, where 0, no pain; 10, worst imaginable pain. Subjects received Inj. Tramadol hydrochloride (1 mg/kg IV as a rescue analgesic whenever VAS score was ≥4. Occurrence of any side effects like nausea, vomiting, sedation, headache and dizziness was also noted. Statistical Analysis Used- Data analysis was done using PASW 18.0 software. Results were analysed by Mann-Whitney U-test, large sample difference in proportion test and Fisher’s Exact test. RESULTS Patients in the pregabalin group had significantly lower pain scores at all the time intervals in comparison to placebo group (p<0.05. Total postoperative tramadol consumption in the pregabalin group was statistically significantly lower than in the control group (p<0.05 and also time to first request for

Laparoscopic cholecystectomy (LC) has traditionally been performed under general anesthesia, however, owing in part to the advancement of surgical and anesthetic techniques, many laparoscopic cholecystectomies have been successfully performed under the spinal anesthetic technique. We hoped to determine the feasibility of segmental epidural anesthesia for LC. Twelve American Society of Anesthesiologists class I or II patients received an epidural block for LC. The level of epidural block and the satisfaction score of patients and the surgeon were checked to evaluate the efficacy of epidural block for LC. LC was performed successfully under epidural block, with the exception of 1 patient who required a conversion to general anesthesia owing to severe referred pain. There were no special postoperative complications, with the exception of one case of urinary retention. Epidural anesthesia might be applicable for LC. However, the incidence of intraoperative referred shoulder pain is high, and so careful patient recruitment and management of shoulder pain should be considered.

Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black boxes and simulators were included. The results indicated any kind of simulator training (black box, VR) to be beneficial at novice level. After VR training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. No clinical follow-up data were found. Optimal learning requires skills training to be conducted as part of a systematic training program. No data on the cost-benefit of simulators were found, the price of a VR simulator begins at EUR 60 000. Theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. The cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. In order to achieve optimal learning a validated training program is needed.

Fluorescence imaging using indocyanine green (ICG) has recently been applied to laparoscopic surgery to identify cancerous tissues, lymph nodes, and vascular anatomy. Here we report the application of ICG-fluorescence imaging to visualize the boundary between the liver and subserosal tissues of the gallbladder during laparoscopic full-thickness cholecystectomy. A patient with a potentially malignant gallbladder lesion was administered 2.5-mg intravenous ICG just before laparoscopic full-thickness cholecystectomy. Intraoperative fluorescence imaging enabled the real-time delineation of both extrahepatic bile duct anatomy and hepatic parenchyma throughout the procedure, which resulted in complete removal of subserosal tissues between liver and gallbladder. Safe and feasible ICG-fluorescence imaging can be widely applied to laparoscopic hepatobiliary surgery by utilizing a biliary excretion property of ICG. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

We recently developed an oval-shaped E•Z Access device designed exclusively for use with the LAP PROTECTOR™ Oval type device (Hakko Co. Ltd., Tokyo, Japan). The transverse abdominal opening diameter made by round-shaped (Alexis® Wound Retractor, Applied Medical, Rancho Santa Margarita, CA; and LAP PROTECTOR™ Round type) and oval-shaped (LAP PROTECTOR™ Oval type) wound retractors was measured and compared in 5 patients with cholecystolithiasis. Each device was placed through a single 25-mm longitudinal umbilical incision, and the length of trocar separation was compared. LESS cholecystectomy was then performed using the oval-shaped E•Z ACCESS/LAP PROTECTOR™. The transverse abdominal opening diameter was maximized with the LAP PROTECTOR™ Oval type device. The average distance between the working-ports for the glove method, round-shaped, and oval-shaped E•Z ACCESS/LAP PROTECTOR™ devices in the 25-mm umbilical incisions were 20 ± 0.8 mm, 24 ± 1.5 mm, and 35 ± 0.8 mm, respectively. Wider trocar separation was achieved using the oval-shaped device, making the surgical procedures easier to perform. No perioperative port-related or surgical complications were observed. LESS cholecystectomy using the E•Z ACCESS Oval type device was found to be technically feasible. The Oval type device appears to allow for wider trocar separation, thereby reducing stress on the surgeon, ensuring patient safety, and providing cosmetic benefits.

The treatment of children with biliary dyskinesia (BD) is controversial. As we recently observed an increasing frequency of referrals for BD in our institution the aim of the study was to re-evaluate the long-term outcome in children with BD. Children with laparoscopic cholecystectomy (LC) for suspected BD between 8/2006 and 5/2011 were included. A pathologic ejection fraction (EF) was defined as <35%. The long-term effect of cholecystectomy was assessed via a Likert scale symptom questionnaire. 82 children (median age 13.5 years, mean BMI 25.8) were included. CCK-HIDA scan was pathologic in 74 children (90.2%). Mean EF was 16.4%. Histology revealed chronic cholecystitis in 48 (58.5%) children and was normal in 30 children (36.5%). The frequency of LC for suspected BD increased by a factor of 4.3 in the last 10 years. Long term follow-up showed that only 23/52 children (44.2%) were symptom-free after LC. Patients with chronic inflammation were more likely to have persistent symptoms (p=0.017). An EF<15% was associated with a resolution of symptoms (p=0.031). The frequency of LC for suspected BD in our institution has increased significantly during recent years. The long-term efficacy in our cohort was only 44.2%. We believe that laparoscopic cholecystectomy is likely helpful in patients with an EF<15%. However, in children with an EF of 15%-35%, based upon our data, we would highly recommend an appropriately thorough pre-op testing to exclude other gastrointestinal disorders prior to consideration of operative management.

Open heart surgery has previously been associated with the use of large volumes of blood products. This paper describes methods of blood conservation and a simple method of intraoperative autotransfusion that together have resulted in minimal blood product usage in elective open heart surgery cases. This has reduced our dependence on blood bank supplies for the performance of elective open heart surgery.

Full Text Available ABSTRACT: CONTEXT AND OBJECTIVE: There are few data in the literature on the frequency of cholecystectomy in Brazil. The frequency of cholecystectomy and associated risk factors were evaluated in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil. DESIGN AND SETTING: Cross-sectional study using baseline data on 5061 participants in São Paulo. METHODS: The frequency of cholecystectomy and associated risk factors were evaluated over the first two years of follow-up of the study and over the course of life. A multivariate regression analysis was presented: odds ratio (OR and 95% confidence interval (95% CI. RESULTS: A total of 4716 individuals (93.2% with information about cholecystectomy were included. After two years of follow-up, 56 had undergone surgery (1.2%: 1.7% of the women; 0.6% of the men. A total of 188 participants underwent cholecystectomy during their lifetime. The risk factors associated with surgery after the two-year follow-up period were female sex (OR, 2.85; 95% CI, 1.53-5.32, indigenous ethnicity (OR, 2.1; 95% CI, 2.28-15.85 and body mass index (BMI (OR, 1.10; 95% CI, 1.01-1.19 per 1 kg/m2 increase. The risk factors associated over the lifetime were age (OR, 1.03; 95% CI, 1.02-1.05 per one year increase, diabetes (OR, 1.92; 95% CI, 1.34-2.76 and previous bariatric surgery (OR, 5.37; 95% CI, 1.53-18.82. No association was found with parity or fertile age. CONCLUSION: Female sex and high BMI remained as associated risk factors while parity and fertile age lost significance. New factors such as bariatric surgery and indigenous ethnicity have gained importance in this country.

Generally, surgeons' perceptions of surgical safety are based on experience and institutional policy. Our recent pilot survey demonstrated that the acceptable duration of surgery and criteria for open conversion during laparoscopic cholecystectomy (LC) vary among workplaces. A web-based survey was distributed to 554 expert LC surgeons in Japan, Korea, and Taiwan. The questionnaire covered LC experience, safety measures and recognition of landmarks, decision-making regarding conversion to open/partial cholecystectomy and the implications of this decision. Overall responses were compared among nations, and then stratified by LC experience level (lifetime cases 200-499, 500-999, and ≥1,000). The response rate was 92.6% (513/554); 67 surgeons with ≤199 LCs were excluded, and responses from 446 surgeons were analyzed. We observed significant differences among nations on almost all questions. Differences that remained after stratification by LC experience were on questions related to acceptable duration of surgery, adoption rates of intraoperative cholangiography, the "critical view of safety" technique, identification of Rouvière's sulcus, recognition of the SS-Inner layer theory, and intraoperative judgment to abandon conventional LC. Even among experts, surgeons' perceptions during LC are workplace-dependent. A novel grading system of surgical difficulty and standardized LC procedures are paramount to generate high-level evidence. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Goossens, Richard H. M.; van Eijk, Daan J.; Lange, Johan F.

2008-01-01

Background Iatrogenic bile duct injury remains a current complication of laparoscopic cholecystectomy. One uniform and standardized protocol, based on the “critical view of safety” concept of Strasberg, should reduce the incidence of this complication. Furthermore, owing to the rapid development of minimally invasive surgery, technicians are becoming more frequently involved. To improve communication between the operating team and technicians, standardized actions should also be defined. The aim of this study was to compare existing protocols for laparoscopic cholecystectomy from various Dutch hospitals. Methods Fifteen Dutch hospitals were contacted for evaluation of their protocols for laparoscopic cholecystectomy. All evaluated protocols were divided into six steps and were compared accordingly. Results In total, 13 hospitals responded—5 academic hospitals, 5 teaching hospitals, 3 community hospitals—of which 10 protocols were usable for comparison. Concerning the trocar positions, only minor differences were found. The concept of “critical view of safety” was represented in just one protocol. Furthermore, the order of clipping and cutting the cystic artery and duct differed. Descriptions of instruments and apparatus were also inconsistent. Conclusions Present protocols differ too much to define a universal procedure among surgeons in The Netherlands. The authors propose one (inter)national standardized protocol, including standardized actions. This uniform standardized protocol has to be officially released and recommended by national scientific associations (e.g., the Dutch Society of Surgery) or international societies (e.g., European Association for Endoscopic Surgery and Society of American Gastrointestinal and Endoscopic Surgeons). The aim is to improve patient safety and professional communication, which are necessary for new developments. PMID:18224485

An unsolved problem of laparoscopic cholecystectomy is the optimal method of removing the gallbladder with thick walls and a large stone burden. Proposed solutions include fascial dilatation, stone crushing, and ultrasonic, high-speed rotary, or laser lithotripsy. Our observation was that extension of the fascial incision to remove the impacted gallbladder was time efficient and did not increase postoperative pain. We reviewed the narcotic requirements of 107 consecutive patients undergoing laparoscopic cholecystectomy. Fifty-two patients required extension of the umbilical incision, and 55 patients did not have their fascial incision enlarged. Parenteral meperidine use was 39.5 +/- 63.6 mg in the patients requiring fascial incision extension and 66.3 +/- 79.2 mg in those not requiring fascial incision extension (mean +/- standard deviation). Oral narcotic requirements were 1.1 +/- 1.5 doses vs 1.3 +/- 1.7 doses in patients with and without incision extension, respectively. The wide range of narcotic use in both groups makes these apparent differences not statistically significant. We conclude that protracted attempts at stone crushing or expensive stone fragmentation devices are unnecessary for the extraction of a difficult gallbladder during laparoscopic cholecystectomy.

Cholecystectomy of an Intrahepatic Gallbladder in an Ectopic Pelvic Liver: A Case Report and Review of the Literature

Rachel Mathis

2017-01-01

Full Text Available Introduction. Ectopic pelvic liver is an exceedingly rare condition usually resulting after repair of congenital abdominal wall defects. Intrahepatic gallbladder is another rare condition predisposing patients to cholelithiasis and its sequelae. We describe a cholecystectomy in a patient with an intrahepatic gallbladder in a pelvic ectopic liver. Presentation of Case. A 33-year-old woman with a history of omphalocele repair as an infant presented with signs and symptoms of symptomatic cholelithiasis and chronic cholecystitis, however, in an unusual location. After extensive workup and symptomatic treatment, cholecystectomy was recommended and performed via laparotomy and hepatotomy using microwave technology for parenchymal hepatic transection. Discussion. Given the rare combination of an intrahepatic gallbladder and an ectopic pelvic liver, advanced surgical techniques must be employed for cholecystectomies, in addition to involvement of hepatobiliary experienced surgeons due to the distortion of the biliary and hepatic vascular anatomy. Conclusion. Cholecystectomy by experienced hepatobiliary surgeons is a safe and effective treatment for cholecystitis in patients with intrahepatic gallbladders in ectopic pelvic livers.

Serious complications continue to occur in laparoscopic cholecystectomy (LC). The commonly used indicators of surgical difficulty such as the duration of surgery are insufficient because they are surgeon and institution dependent. We aimed to identify appropriate indicators of surgical difficulty during LC. A total of 26 Japanese expert LC surgeons discussed using the nominal group technique (NGT) to generate a list of intraoperative findings that contribute to surgical difficulty. Thereafter, a survey was circulated to 61 experts in Japan, Korea, and Taiwan. The questionnaire addressed LC experience, surgical strategy, and perceptions of 30 intraoperative findings listed by the NGT. The response rate of the survey was 100%. There was a statistically significant difference among nations regarding the duration of surgery and adoption rate of safety measures and recognition of landmarks. The criteria for conversion to an open or subtotal cholecystectomy were at the discretion of each surgeon. In contrast, perceptions of the impact of 30 intraoperative findings on surgical difficulty (categorized by factors related to inflammation and additional findings of the gallbladder and other intra-abdominal factors) were consistent among surgeons. Intraoperative findings are objective and considered to be appropriate indicators of surgical difficulty during LC. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

of cholecystectomy on the bile flow has not yet been investigated. The goal of the current study was to examine the dynamics and normal variations of bile flow by quantitative hepatobiliary scintigraphy before and after cholecystectomy in a group of patients with uncomplicated gallstone disease. METHODS: Twenty...... patients were evaluated before and after cholecystectomy through cholecystokinin octapeptide-augmented quantitative hepatobiliary scintigraphy, and quantitative parameters of bile emptying (Tmax: time to peak activity, T1/2: half-emptying time before and after cholecystokinin octapeptide and duodenum...... appearance time) were determined and then compared. RESULTS: Before operation, the bile outflow displayed wide variations, with a moderately delayed common bile duct emptying time in some patients. After cholecystectomy, the T1/2 of the common bile duct decreased significantly when compared...

Full Text Available Elections in Serbia have been held quite often over the past 26 years. Yet, of all elections that have taken place since the introduction of the multiparty system in 1990, the elections held on April 24 2016, were the most confusing. They were held early, but were neither a product of political, nor economic crisis. So why were they necessary?

An ultrasound dissector especially developed for laparoscopic surgery was used during laparoscopic cholecystectomy on 34 patients. The ultrasound power, the volume of suction and irrigation could be determined individually at the generator and activated during the operation with a foot pedal. With the dissector it was possible to fragmentate, emulgate and aspirate simultaneously fat tissue as well as infected edematous structures. The cystic artery and cystic duct, small vessels, lymphatic and connective tissue were not damaged. Therefore this system seems to be excellent for the preparation of Calot's trigonum and blunt dissection of the gallbladder out of its bed, particularly in fatty, acute or chronic infected tissue. No complications were observed within the peri- and postoperative period.

Full Text Available Abstract 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.

Objectives: This study adds to the ongoing discussion on how to ease the transition from undergraduate medical training to postgraduate training. In the Netherlands there is no central matching system for admission to residency. Medical school graduates just apply for a position in an open job market. Many choose to acquire general or specialty-specific clinical experiences after the medical degree before residency, to further explore career opportunities and to increase their chances to get into their preferred specialty. To shorten this gap between undergraduate and the start of postgraduate training, the sixth and final year of most Dutch medical schools is designed as a "transitional year". Students work with more clinical responsibilities than in the earlier clerkships, and this year includes many elective options. Our study focuses on these elective options and explores how medical students use these transitional year electives to prepare for transition to postgraduate training. Methods: In 2012-2013 we asked all 274 graduating students at one Dutch medical school to complete an open-answer questionnaire with the following topics: their preferred specialty at the start of the transitional year, electives they chose during this year and reasons for these choices, and whether the transitional year electives changed their career considerations. Questionnaire results were coded by two researchers and were discussed with all members of the research team. Results: A total of 235 students responded (86%). Answers about motivation for choices revealed that most electives where chosen for career orientation and to optimize chances to get into a residency program. Students also focused on additional experiences in specialties related to their preferred specialty. Many students chose electives logically related to each other, e.g. combinations of surgery and radiology. About two-thirds of the respondents stated that their elective experiences did confirm their specialty

Septic complications are rare following laparoscopic cholecystectomy if prophylactic antibiotics are given, as demonstrated in previous studies. Antibiotic treatment may be unnecessary and, therefore, undesirable, so we compared two forms of prophylaxis: a cephalosporin antibiotic and bag extraction of the dissected gallbladder. A total of 76 patients undergoing laparoscopic cholecystectomy were randomised to either receive an antibiotic or to have their gallbladder removed from the abdomen in a plastic bag. Complicated cases were excluded. There was a total of 6 wound infections (7.9%), 3 in each of the study groups. All these were associated with skin commensals. There were no other septic complications. Bacteriological studies grouped the organisms isolated from the bile and the wound as potential pathogens and likely commensals. A total of 10 potential pathogens were isolated, 9 of which were found in the group receiving antibiotics. We conclude that septic sequelae of uncomplicated laparoscopic cholecystectomy are uncommon, but clearly not entirely prevented by antibiotic or mechanical prophylaxis. Prophylactic antibiotics may not be required in uncomplicated laparoscopic cholecystectomy. Further study is warranted.

Morpho-functional gastric pre-and post-operative changes in elderly patients undergoing laparoscopic cholecystectomy for gallstone related disease

Science.gov (United States)

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

Sunder Goyal

2012-08-01

Materials and Methods: In a private rural medical college, 150 patients were selected prospectively for laparoscopic cholecystectomy, under low-pressure (8mmHg pneumoperitoneum and under spinal anesthesia over a span of one and a half years. Injection bupivacaine (0.5% was used for spinal anesthesia. All ports were made in a head-down position to avoid hypotension. Shoulder pain was managed by reassurance as well as by diverting the attention and sedation in a few cases. Results: We successfully performed the operations in 145 patients without major complications. Spinal anesthesia was converted to general anesthesia in five patients due to severe shoulder pain. Age varied between 21 and 75 years. Duration of operation time (skin to skin was between 40 and 80 minutes. Twenty-nine patients complained of right shoulder pain. Most of them were managed by reassurance from the anesthetist and a few needed an injection of fentanyl along with midazolam. Conclusion: Laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum is feasible and safe under spinal anesthesia. Incidence of postoperative shoulder pain and complications are comparable with laparoscopic cholecystectomy under general anesthesia. [Arch Clin Exp Surg 2012; 1(4.000: 224-228

We aimed to investigate the short-term effect of laparoscopic surgery on serum thiol-disulfide homeostasis levels as a marker of oxidant stress of surgical trauma in elective laparoscopic cholecystectomy patients. Venous blood samples were collected, and levels of native thiols, total thiols, and disulfides were determined with a novel automated assay. Total antioxidant capacity (measured as the ferric-reducing ability of plasma) and serum ischemia modified albumin, expressed as absorbance units assayed by the albumin cobalt binding test, were determined. The major findings of the present study were that native thiol (283 ± 45 versus 241 ± 61 μmol/L), total thiol (313 ± 49 versus 263 ± 67 μmol/L), and disulfide (14.9 ± 4.6 versus 11.0 ± 6.1 μmol/L) levels were decreased significantly during operation and although they increased, they did not return to preoperation levels 24 hours after laparoscopic surgery compared to the levels at baseline. Disulfide/native thiol and disulfide/total thiol levels did not change during laparoscopic surgery. The decrease in plasma level of native and total thiol groups suggests impairment of the antioxidant capacity of plasma; however, the delicate balance between the different redox forms of thiols was maintained during surgery.

As conventional laparoscopic procedural training requires live animals or cadaver organs, virtual simulation seems an attractive alternative. Therefore, we compared the transfer of training for the laparoscopic cholecystectomy from porcine cadaver organs vs virtual simulation to surgery in a live animal model in a prospective randomized trial. After completing an intensive training in basic laparoscopic skills, 3 groups of 10 participants proceeded with no additional training (control group), 5 hours of cholecystectomy training on cadaver organs (= organ training) or proficiency-based cholecystectomy training on the LapMentor (= virtual-reality training). Participants were evaluated on time and quality during a laparoscopic cholecystectomy on a live anaesthetized pig at baseline, 1 week (= post) and 4 months (= retention) after training. All research was performed in the Center for Surgical Technologies, Leuven, Belgium. In total, 30 volunteering medical students without prior experience in laparoscopy or minimally invasive surgery from the University of Leuven (Belgium). The organ training group performed the procedure significantly faster than the virtual trainer and borderline significantly faster than control group at posttesting. Only 1 of 3 expert raters suggested significantly better quality of performance of the organ training group compared with both the other groups at posttesting (p virtual trainer group did not outperform the control group at any time. For trainees who are proficient in basic laparoscopic skills, the long-term advantage of additional procedural training, especially on a virtual but also on the conventional organ training model, remains to be proven.

Full Text Available On September 15, 2011 a record-high turn-out of 88 percent of the approx. 4 million Danes eligible to vote for the Danish parliament, the Folketing, was reached. This paper gives a short descriptive summary of the 2011 Danish election campaign. Irrespective of which side would win the position as primeminister, one thing was given: an exceptional era in Danish politics was coming to an end. After ten years of a Right Liberal-Conservative minority government supported by the Danish People's Party, Danish poli-tics would return to its classic modus operandi of centrist parties determining the prime-minister. By a margin of a few thousand votes, the red block won the elections and the new prime minister of Denmark is the Social Democrat Helle Thorning-Schmidt. This article describes the political context prior to the election campaign, the course of the election campaign, furthermore it presents the election results in a historical perspective and shortly discusses the challenges the new government is facing.

To evaluate a newly developed cholecystectomy technique which combines classical dissection with currently available mini-instrumentation (3 and 5 mm) and removal of the gallbladder through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. The resected gallbladder was removed through a short gastrotomy on the anterior gastric wall, thereby minimizing abdominal wall trauma and permitting the patient to resume physical activity more quickly with no risk of trocar herniation. Cholecystectomy was performed by the described technique in 18 of 23 eligible patients between April 2008 and August 2008. There were seven males and 11 females with a mean age of 48 (range: 28-77); median BMI was 30 kg/m2 (range: 22-36). Eleven patients had a gallstone larger than 12 mm. There were no postoperative complications and recovery was rapid for all patients in our study. This procedure is technically feasible, safe and reproducible; results are good with minimal trauma to the abdominal wall. Normal physical activity can be rapidly resumed with no risk of incisional hernia.

Full Text Available Purpose. Percutaneous cholecystostomy (PC has increasingly been used as bridge to surgery as well as sole treatment for patients with acute cholecystitis (AC. The aim of the study was to assess the outcome after PC compared to acute cholecystectomy in patients with AC. Methods. A review of medical records was performed on all patients residing in Stockholm County treated for AC in the years 2003 and 2008. Results. In 2003 and 2008 altogether 799 and 833 patients were admitted for AC. The number of patients treated with PC was 21/799 (2.6% in 2003 and 50/833 (6.0% in 2008. The complication rate (Clavien-Dindo ≥ 2 was 4/71 (5.6% after PC and 135/736 (18.3% after acute cholecystectomy. Mean (standard deviation hospital stay was 11.4 (10.5 days for patients treated with PC and 5.1 (4.3 days for patients undergoing acute cholecystectomy. After adjusting for age, gender, Charlson comorbidity index, and degree of cholecystitis, the hospital stay was significantly longer for patients treated with PC than for those undergoing acute cholecystectomy (P<0.001 but the risk for intervention-related complications was found to be significantly lower (P=0.001 in the PC group. Conclusion. PC can be performed with few serious complications, albeit with a longer hospital stay.

In order to prevent unexpected events such as aspiration pneumonia, cerebral angiography has been performed under fasting in most cases. We investigated prospectively the necessity of fasting before elective cerebral angiography. The study is an open-labeled clinical trial without random allocation. In total, 2554 patients who underwent elective cerebral angiography were evaluated on development of nausea, vomiting, and pulmonary aspiration during and after angiography. Potential risks and benefits associated with fasting were provided in written documents and through personal counseling to patients before the procedure. The patients chose their fasting or nonfasting option. No restriction in diet was given after angiography. The patients were observed for 24 hours. Nausea and vomiting during and within 1 hour after angiography was considered as a positive event associated with cerebral angiography. The overall incidence of nausea and vomiting during and within 1 hour after angiography was 1.05% (27/2554 patients). There was no patient with pulmonary aspiration. No statistical difference in nausea and vomiting development between the fasting and the diet groups was found. The incidence of nausea and vomiting associated with cerebral angiography is low and not affected by diet or fasting. Pulmonary aspiration had no difference between the diet and the fasting group. Our study suggests that fasting may not be necessary for patients who undergo elective cerebral angiography.

How competent a politician looks, as assessed in the laboratory, is correlated with whether the politician wins in real elections. This finding has led many to investigate whether the association between candidate appearances and election outcomes transcends cultures. However, these studies have largely focused on European countries and Caucasian candidates. To the best of our knowledge, there are only four cross-cultural studies that have directly investigated how face-based trait inferences correlate with election outcomes across Caucasian and Asian cultures. These prior studies have provided some initial evidence regarding cultural differences, but methodological problems and inconsistent findings have complicated our understanding of how culture mediates the effects of candidate appearances on election outcomes. Additionally, these four past studies have focused on positive traits, with a relative neglect of negative traits, resulting in an incomplete picture of how culture may impact a broader range of trait inferences. To study Caucasian-Asian cultural effects with a more balanced experimental design, and to explore a more complete profile of traits, here we compared how Caucasian and Korean participants’ inferences of positive and negative traits correlated with U.S. and Korean election outcomes. Contrary to previous reports, we found that inferences of competence (made by participants from both cultures) correlated with both U.S. and Korean election outcomes. Inferences of open-mindedness and threat, two traits neglected in previous cross-cultural studies, were correlated with Korean but not U.S. election outcomes. This differential effect was found in trait judgments made by both Caucasian and Korean participants. Interestingly, the faster the participants made face-based trait inferences, the more strongly those inferences were correlated with real election outcomes. These findings provide new insights into cultural effects and the difficult question of

Full Text Available Abstract Background and goal of study: After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption. Materials and methods: We have randomized 76 patients undergoing laparoscopic cholecystectomy to receive either subcostal transversus abdominis plane block (n = 38 or standard postoperative analgesia (n = 38. First group received bilateral ultrasound guided subcostal transversus abdominis plane block with 20 mL of 0.33% bupivacaine per side before operation and tramadol 1 mg.kg−1 IV for pain breakthrough (≥6. Second group received after operation tramadol 1 mg.kg−1/6 h as standard hospital analgesia protocol. Both groups received acetaminophen 1 g/8 h IV and metamizole 2.5 g/12 h. Pain at rest was recorded for each patient using NR scale (0–10 in period of 10 min, 30 min, 2 h, 4 h, 8 h, 12 h and 16 h after the surgery. Results and discussion: We obtained no difference between groups according age, weight, intraoperative fentanyl consumption and duration of surgery. Subcostal transversus abdominis plane block significantly reduced postoperative pain scores compared to standard analgesia in all periods after surgery. Tramadol consumption was significantly lower in the subcostal transversus abdominis plane (24.29 ± 47.54 g than in the standard analgesia group (270.2 ± 81.9 g (p = 0.000. Conclusion: Our results show that subcostal transversus abdominis plane block can provide superior postoperative analgesia and reduction in opioid requirements after laparoscopic cholecystectomy.

After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption. We have randomized 76 patients undergoing laparoscopic cholecystectomy to receive either subcostal transversus abdominis plane block (n=38) or standard postoperative analgesia (n=38). First group received bilateral ultrasound guided subcostal transversus abdominis plane block with 20mL of 0.33% bupivacaine per side before operation and tramadol 1mg.kg -1 IV for pain breakthrough (≥6). Second group received after operation tramadol 1mg.kg -1 /6h as standard hospital analgesia protocol. Both groups received acetaminophen 1g/8h IV and metamizole 2.5g/12h. Pain at rest was recorded for each patient using NR scale (0-10) in period of 10min, 30min, 2h, 4h, 8h, 12h and 16h after the surgery. We obtained no difference between groups according age, weight, intraoperative fentanyl consumption and duration of surgery. Subcostal transversus abdominis plane block significantly reduced postoperative pain scores compared to standard analgesia in all periods after surgery. Tramadol consumption was significantly lower in the subcostal transversus abdominis plane (24.29±47.54g) than in the standard analgesia group (270.2±81.9g) (p=0.000). Our results show that subcostal transversus abdominis plane block can provide superior postoperative analgesia and reduction in opioid requirements after laparoscopic cholecystectomy.

2003-07-01

Full Text Available Background. Situs inversus viscerum totalis (reciprocally reversed position of internal organs is a rare case with genetic predisposition, inherited autosomnously recessive. The presented case involves an older patient with complete transposition of internal organs having acute calculous cholecystitis, which was successfully performed the laparoscopic cholecystectomy. Whilst the production of biliary stones in a case of transposed internal organs is very rare, it may well represent a diagnostic problem. It is not, however, the contraindication for laparoscopic surgery.Patients and methods. The case presents a 64-year-old patient, whose persistent biliary colic trouble eventually resulted in acute cholecystitis. Following routine diagnostics, a laparoscopic cholecystectomy was performed and the patient was released in domestic care after three day hospitalization.Conclusions. The laparoscopic cholecystectomy may also be safely performed in a patient with reciprocal transposition of all internal organs, but it is imperative to consider the fact that the extra-hepatic anatomy of gall bladder and vascular system is the mirror image of normal, right-hand positioned liver.

Efficient planning increasingly becomes an indispensable tool for management of both companies and public organizations. This is also the case for high school management in Denmark, because the growing individual freedom of the students to choose courses makes planning much more complex. Due...... to reforms, elective courses are today an important part of the curriculum, and elective courses are a good way to make high school education more attractive for the students. In this article, the problem of planning the elective courses is modeled using integer programming and three different solution...... for the Elective Course Planning Problem has been described in the literature before. The proposed algorithms are tested on data sets from 98 of the 150 high schools in Denmark. The tests show that for the majority of the problems, the optimal solution can be obtained within the one hour time bound. Furthermore...

Endoscopic sphincterotomy (ES) is one of the most important advances in the treatment of common bile duct (CBD) stones. However, the use of ES to remove CBD stones in high-risk patients without cholecystectomy is still debatable. The aim of this study was to compare the efficacy of a wait-and-see policy versus cholecystectomy after ES for CBD stones in high-risk patients with co-existing cholelithiasis. A total of 162 patients after undergoing ES with the clearance of CBD stones were randomised after informed consent to cholecystectomy or conservative management of their gallbladder stones. The results indicated that cholecystectomy after ES for CBD stones significantly reduced the biliary complications in high-risk patients. Every patient who has both CBD stones and gallstones with significant co-morbid illnesses, after clearance of CBD stones by ES, should undergo early cholecystectomy.

2017-12-15

According to the current literature, biliary lithiasis is a worldwide-diffused condition that affects almost 20% of the general population. The rate of common bile duct stones (CBDS) in patients with symptomatic cholelithiasis is estimated to be 10% to 33%, depending on patient's age. Compared to stones in the gallbladder, the natural history of secondary CBDS is still not completely understood. It is not clear whether an asymptomatic choledocholithiasis requires treatment or not. For many years, open cholecystectomy with choledochotomy and/or surgical sphincterotomy and cleaning of the bile duct were the gold standard to treat both pathologies. Development of both endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic surgery, together with improvements in diagnostic procedures, influenced new approaches to the management of CBDS in association with gallstones. We decided to systematically review the literature in order to identify all the current therapeutic options for CBDS. A systematic literature search was performed independently by two authors using PubMed, EMBASE, Scopus and the Cochrane Library Central. The therapeutic approach nowadays varies greatly according to the availability of experience and expertise in each center, and includes open or laparoscopic common bile duct exploration, various combinations of laparoscopic cholecystectomy and ERCP and combined laparoendoscopic rendezvous. Although ERCP followed by laparoscopic cholecystectomy is currently preferred in the majority of hospitals worldwide, the optimal treatment for concomitant gallstones and CBDS is still under debate, and greatly varies among different centers.

Full Text Available Taiwan held its first combined national elections on 14 January 2012. Though the Democratic Progressive Party (DPP, the largest opposition party, fared much better in the Legislative Yuan elections than it did in 2008, DPP presidential contender Tsai Ying-wen’s (Cai Yingwen clear defeat at the hands of the Kuomintang (KMT, Guomindang incumbent, Ma Ying-jeou (Ma Yingjiu, in the presidential race came as a surprise. The article examines the election campaigns of both Tsai and Ma, summarizes the election results, and analyses the reasons why the DPP failed to retake the presidency. It then discusses the post-election debate within the DPP on the future of its China policy and ponders what can be expected from the second Ma administration.

Assessment of indicators for predicting choledocholithiasis before laparoscopic cholecystectomy

International Nuclear Information System (INIS)

Alam, Mohammed K.

1998-01-01

The objective of this report was to study the sensitivity of indicators used for predicting bile duct stones and their endoscopic removal before laparoscopic cholecystectomy. A retrospective study was conducted on 104 patients who successfully underwent endoscopic retrograde cholangiopancreatogram (ERCP) before laparoscopic cholecysectomy at Riyadh Medical Complex between 1992 and 1994 (1412H-1414H). Six indicators --- jaundice, biliary pancreatitis, stones in bile duct on sonography, dilated bile duct (>7mm) on ultrasonography, dilated bile duct with deranged liver function test and deranged liver function test without jaundice ---were used for suspecting choledocholithiasis and endoscopic removal before laparoscopic cholecystectomy. Ultrasound correctly predicted bile duct stone in 75%, followed by dilated bile duct with deranged liver function test (46%). Clinical jaundice and biliary pancreatitis were equally sensitive indicators (42% each). Sensitivity of only dilated bile duct on ultrasonography in predicting duct stone was 36%. Deranged liver function without jaundice was the least sensitive (22%) of the predictors. Overall, these indicators correctly diagnosed bile duct stones in 34% of patients. Until laparoscopic exploration of bile duct or a noninvasive technique, such as magnetic resonance cholangiopancreatogram (MRCP), is widely available, these predictors will help in selecting patients with bile duct stones for preoperative removal. Other workers have suggested combining these indicators to improve the predictive value. (author)

Laparoscopic upper abdominal surgery can cause spontaneous respiration due to diaphragmatic stimulation and intra-abdominal CO 2 inflation. Therefore, sufficient muscle relaxation is necessary for a safe surgical environment. We investigated if the combination of rocuronium and cisatracurium can counteract the delayed onset of cisatracurium's action and delayed recovery of muscle relaxation and whether the dosage of rocuronium, which is metabolized hepatically, can be reduced. A total of 75 patients scheduled for laparoscopic cholecystectomy with an American Society of Anesthesiology physical status I-II, in the age range of 20-60 years, and with a 20-30 kg/m 2 body mass index were included in the study. The patients were divided into the following groups: combination group (Group RC, rocuronium 0.3 mg/kg and cisatracurium 0.05 mg/kg), rocuronium group (Group R, rocuronium 0.6 mg/kg), and cisatracurium group (Group C, cisatracurium 0.1 mg/kg), and the onset, 25% duration, recovery index, and addition/time ratio were measured. Patients in Group RC exhibited a significantly different addition/time ratio compared with patients in the other two groups (p = 0.003). During laparoscopic cholecystectomy, the 95% effective dose of rocuronium in combination with cisatracurium is expected to provide a sufficient muscle relaxant effect.

Pain treatment in laparoscopic cholecystectomy, which is performed in increasing numbers as an ambulatory procedure, is an important issue.Although laparoscopic cholecystectomy is regarded as an ambulatory procedure, patients are often hospitalized due to pain and this increases opioid consumption and side effects caused by opioids. This study aims at evaluating the efficacy of adding dexketoprofen trometamol to tramadol with patient controlled analgesia (PCA) in postlaparoscopic cholecystectomy pain treatment. 40 patients in ASA I-II risk groups aged between 18-65 years were enrolled in the study and were randomized using closed envelope method. In Group TD 600 mg tramadol and 100 mg dexketoprofen trometamol, in Group T 600 mg tramadol was added to 100 ml 0.9% normal saline for PCA. 8 mg lornoxicam iv was given if VAS >40 in the postoperative period. There was no statistically significant difference in terms of adverse effects (hypotension, bradycardia, sedation) but in Group T 4 patients complained of nausea and 3 complained of vomiting. Opioid consumption was lower and patient satisfaction was higher in group TD. This study has shown that adding dexketoprofen trometamol to tramadol in patient controlled analgesia following laparoscopic cholecystectomy lowers VAS scores, increases patient satisfaction and decreases opioid consumption.

Socioeconomic differences in waiting times for elective surgery: a population-based retrospective study

2012-08-01

Full Text Available Abstract Background Widespread literature on inequity in healthcare access and utilization has been published, but research on socioeconomic differences in waiting times is sparse and the evidence is fragmentary and controversial. The objective of the present study is the analysis of the relationship between individual socioeconomic level and waiting times for in-hospital elective surgery. Methods We retrospectively studied the waiting times experienced by patients registered on hospital waiting lists for 6 important surgical procedures by using the Hospital Discharge Database (HDD of the Piedmont Region (4,000,000 inhabitants in the North West of Italy from 2006 to 2008. The surgical procedures analyzed were: coronary artery by-pass (CABG, angioplasty, coronarography, endarterectomy, hip replacement and cholecystectomy. Cox regression models were estimated to study the relationship between waiting times and educational level taking into account the confounding effect of the following factors: sex, age, comorbidity, registration period, and Local Health Authorities (LHA as a proxy of supply. Results Median waiting times for low educational level were higher than for high educational level for all the selected procedures. Differences were particularly high for endarterectomy and hip replacement. For all considered procedures, except CABG, an inverse gradient between waiting times and educational level was observed: the conditional probabilities of undergoing surgery were lower among individuals with a low to middle level education than for individuals with a higher level of education after adjustment for sex, age, comorbidities, registration period, and LHAs. For most procedures the effect decreases over the follow up period. Conclusions The results of the study show evidence of inequalities in access to elective surgery in Italy. Implementation of policies aimed to promote national information initiatives that guarantee wider access to those

The Effect of Cholecystectomy on the Histology of Antrum and Helicobacter Pylori Colonization

Directory of Open Access Journals (Sweden)

Hüseyin Özer

2013-07-01

Full Text Available Aim: Notwithstanding cholecystectomy’s being the standard cure for symptomatic gallbladder stones, it might as well trigger changes that result in the increase of duodenogastric reflux and the emergence of relevant clinic and laboratorial data. The aim of this thesis is to explore the effect of cholecystectomy on the duodenogastric reflux, histopathologic changes in the antral mucosa and Helicobacter pylori colonization. Material and Method: This prospective research is based upon data collected from 45 patients (28 of them being female and 17 of them being male patients with an average age of 50.9, who would undergo cholecystectomic surgery. Upper gastrointestinal endoscopy has been performed on patients before the operation and at least two months after the operation in order to examine the existence of bile in the stomach. The tissues removed from the antrum during these endoscopic biopsies have been examined to spot the histopathologic changes and the existence of Helicobacter pylori in the mucosa (chronic gastritis, activation findings, and intestinal metaplasia. Results: Duodenogastric reflux, chronic gastritis, and intestinal metaplasia have been observed to increase significantly after cholecystectomy (p<0.001 for duodenogastric reflux and chronic gastritis, p<0.05 for intestinal metaplasia. On the other hand, no significant data have been attained in terms of activation findings and the existence of H.pylori before and after the operation. Discussion: Although cholecystectomy cause duodenogastric reflux and histopathologic changes in the antrum, it does not affect  H.pylori colonization.

[Preoperatory sonography efficiency in paediatric patients with cholelithiasis undergoing laparoscopic cholecystectomy].

2009-01-01

Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography. We made a retrospective study of 42 patients undergoing laparoscopic cholecystectomy due to symptomatic biliary lithiasis during the last 15 years, with ages between 18 months and 17-years-old (mean age 9,6-years-old) and weight between 11 and 70 kg (mean weight 42 kg) at the moment of surgery. Six of them had haematological illnesses, 17 came to the hospital because of acute abdominal pain, 10 had been studied because of recurrent abdominal pain and 9 had casual diagnoses. Abdominal sonography was performed in all patients 24-48 hours before surgery. Four children were diagnosed of biliary duct lithiasis: two choledocolithiasis and two stones in the cystic duct. One of the cystic stones was extracted in the operating room and the rest resolved spontaneously. One patient presented dilatation of choledocal duct after surgery, without any stones' evidence. Also this patient resolved spontaneously. We had no complications. Biliary lithiasis is not frequent in children, even if it seems to be increasing. A few of these patients will suffer of choledocolithiasis. The intraoperatory exploration of the biliary tree during laparoscopic surgery is technically difficult due the small size of paediatric patients. Cholangiography is not always successful and can produce some important complications as pancreatitis. Preoperative sonography 24-48 hours before surgery is a safe and efficient method for the diagnosis and follow-up of paediatric patients with biliary lithiasis undergoing laparoscopic cholecystectomy. It is safe enough to be performed without intraoperatory cholangiography.

Gerlinzani, S; Tos, M; Gornati, R; Molteni, B; Poliziani, D; Taschieri, A M

2000-04-01

Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan. Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. Ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.

THE VALUE OF A PERSONAL BRAND IN THE ELECTIONS. THE QUANTITATIVE ANALYSIS FOR ELECTION LAWS APPLIED IN LOCAL ELECTIONS IN ROMANIA

Directory of Open Access Journals (Sweden)

GHIUȚĂ OVIDIU-AUREL

2015-03-01

Full Text Available This paper analyses the concepts of brand equity and brand value as found in the professional scientific literature and proposes an innovative research approach of the brand value of uninominal candidates running in the local elections in Romania in 2012 or of any other candidates that run in similar elections in terms of voting procedures. The originality of the paper consists in the fact that we have created a formula that will be used to measure the brand equity of these candidates depending on the results obtained by the party whose candidate is running in the elections, as compared to the other candidates and the other parties. This paper presents the methodology used to validate these formulae for measuring the theoretical score that should have been reached by a party’s candidate whose brand equals zero. In order to identify the contribution of the candidate’s brand to the respective result in our future research, we will make the difference and calculate the ratio between the real score and this theoretical score for a null personal brand. The present research, conducted from a positive perspective, resorts to a behavioural approach that allowsfor the measurement of the personal brand of candidates running for elections in certain electoral systems. This research is valuable for professionals as well as one can identify the candidates that are unsuitable for future elections, since a negative brand equity, accompanied by increased awareness (reached during the most recent elections, at the latest can hardly be turned into a positive image. Moreover, this analysis can be used in the internal assessments conducted by each political party after elections.

2010-12-01

To determine the feasibility and efficacy of the laparoscopic intraoperative rendezvous technique for common bile duct stones (CBDS). Case series. Verona University Hospital, Verona, Italy. A total of 110 patients were enrolled in the study; 47 had biliary colic; 39, acute cholecystitis; 19, acute biliary pancreatitis; and 5, acute biliary pancreatitis with associated acute cholecystitis. In all patients, CBDS diagnosis was reached by intraoperative cholangiography. Intraoperative endoscopy with rendezvous performed during laparascopic cholecystectomy for confirmed CBDS; for such a procedure, a transcystic guide wire was positioned into the duodenum. Intraoperative endoscopy with rendezvous was performed for retrieved CBDS during a laparoscopic cholecystectomy. Laparoscopic rendezvous feasibility, morbidity, postprocedure pancreatitis, and mortality. The laparoscopic rendezvous proved to be feasible in 95.5% (105 of 110 patients). The rendezvous failed in 3 cases of successfully performed laparoscopic cholecystectomy, and a conversion of the laparoscopy was needed in 2 cases of successful rendezvous. Two major complications and 2 cases of bleeding were registered after sphincterotomy was successfully performed with rendezvous, and severe acute pancreatitis complicated a traditional sphincterotomy performed after a failed rendezvous. Rendezvous is a feasible option for treatment of CBDS; it allows one to perform only 1 stage of treatment, even in acute cases such as cholecystitis and pancreatitis. Positioning of the guide wire may allow reduced complications secondary to papilla cannulation but not those of the endoscopic sphincterotomy.

Isolated Right Segmental Hepatic Duct Injury Following Laparoscopic Cholecystectomy

International Nuclear Information System (INIS)

Perini, Rafael F.; Uflacker, Renan; Cunningham, John T.; Selby, J. Bayne; Adams, David

2005-01-01

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

At present there are no well-established pharmacological approaches in the management of post-cholecystectomy alkaline reactive gastritis. The aim of this study was to assess the effect of sucralfate versus rabeprazole or no treatment on dyspeptic symptoms and endoscopic/histological signs in a population of patients with a history of cholecystectomy and evidence of alkaline reactive gastritis. Sixty dyspeptic patients fulfilling the following criteria of inclusion took part in this study: (1) a history of cholecystectomy; (2) no use of anti-inflammatory steroidal and non-steroidal drugs, or abuse of alcohol; (3) evidence of abundant gastric bile reflux at endoscopy; (4) endoscopic signs of chronic gastritis; (5) histological signs of chronic gastritis; and (6) absence of Helicobacter pylori infection. Dyspeptic symptoms were evaluated by means of a self-administered validated questionnaire. Patients included in the study were randomly assigned to one of three treatment groups for 3 months: sucralfate, rabeprazole, observation. Patients were re-evaluated at the end of the treatment. Sucralfate and rabeprazole therapies were both able to significantly reduce epigastric pain, heartburn, bloating and halitosis. Endoscopic/histological signs were lower in both treatment groups compared to the observation group. Both sucralfate and rabeprazole therapies are effective treatment options in the patients with alkaline gastritis when compared with observation.

Full Text Available Abstract The Legal Institution of the General Election in Indonesia has an important role in the process of elections to realize the sovereignty of the people. The legal institution is independent as mandated of the Indonesian constitution The 1945 Constitution. In the Election organizers as a chapter of the 1945 Constitution stating that the Election Commission shall be independent and impartial toward participating in the election and political party. However in practice this task is not easy and can be run smoothly it is difficult to maintain a balanced relationship between the participant election commissions. This research is a descriptive analytic one using juridical normative approach to study the legal principles legal synchronization. The technique being used to gather data is librarian research supported by field research using interview and questionnaire technique. The data being gathered are analyzed qualitatively. The result of the research shows that the legal institution the general election in undertaking has not been independent as expected because for institutional and administrative for has not been independence and not impartiality and not professionalism. The rules in the process of elections is it not the election system and achievement of justice.

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.

Second-Rate Coverage of Second-Order Elections: Czech and Slovak Elections to the EP in the Media

Full Text Available Elections to the European Parliament (EP are considered second-order national elections (SOE. The SOE model suggests that there is a qualitative difference between different types of elections depending on the perception of what is at stake. Compared to first order elections, in second order elections there is less at stake because they do not determine the composition of government. Given that voters behave differently in second-order elections, the question arises: do the media also consider second-order elections less interesting and therefore devote to them less coverage? The media play a crucial role in informing citizens about such events as elections; they function as intermediaries between the electorate and the political arena. However, little is known about how EU issues are covered in the media, particularly in the new EU member states. Conducting a content analysis and applying the second-order election model, this paper analyses TV news coverage of the 2004 and 2009 European elections in the Czech Republic and Slovakia in a comparative fashion. The findings are discussed in the light of existing research literature on the EU’s legitimacy as well as its alleged democratic and communication deficit, not least because the EU relies on the media in strengthening (albeit indirectly its legitimacy by increasing citizen awareness of its activities.

Full Text Available Background and Objective: Today, the control or reduction of pain and anxiety is considered to be of great importance. Thus, the use of complementary medicine therapies has gained much attention. The present study was performed with the aim to investigate the effect of music on anxiety and pain in patients undergoing cholecystectomy. Materials and Method: This single-blind randomized clinical trial was performed on 60 patients undergoing cholecystectomy in Sina Hospital of Tabriz, Iran, in 2013. Subjects were selected through simple random sampling method and divided into intervention (n = 30 and control groups (n = 30 using a random number table. For the intervention group, 8 and 16 hours after surgery, the music was played for 15-30 minutes. For the control group, routine care was performed. Data collection tools included demographic information form and a visual analogue scales (VAS for anxiety and pain. Data analysis was performed using SPSS software version 13, and chi-square, Students’ independent t-test, and repeated measures ANOVA. Results: Comparison of changes in anxiety and pain in the two groups showed a significant decrease in anxiety 8 hours (6/27 ± 3.23 and 16 hours (5.33 ± 3.03 after surgery (P = 0.001. Moreover, the reduction in pain 8 hours (7.51 ± 1.83 and 16 hours (6.61 ± 1.86 after surgery was greater in the intervention group than the control group (P = 0.001. Conclusion: The results illustrated the positive impact of music on anxiety and pain reduction 8 and 16 hours after cholecystectomy. Therefore, this method can be used as an inexpensive and non-invasive nursing care technique.

The reported incidence (0.16-1.5 %) of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is higher than during open cholecystectomy and has not decreased over time despite increasing experience with the procedure. The "critical view of safety" (CVS) technique may help to prevent BDI when certain criteria are met prior to division of any structures. This study aimed to evaluate the adherence of practicing surgeons to the CVS criteria during LC and the impact of a training intervention on CVS identification. LC procedures of general surgeons were video-recorded. De-identified recordings were reviewed by a blinded observer and rated on a 6-point scale using the previously published CVS criteria. A coaching program was conducted, and participating surgeons were re-assessed in the same manner. The observer assessed ten LC videos, each involving a different surgeon. The CVS was adequately achieved by two surgeons (20 %). The remaining eight surgeons (80 %) did not obtain adequate CVS prior to division of any structures, despite two surgeons dictating that they did; the mean score of this group was 1.75. After training, five participating surgeons (50 %) scored > 4, and the mean increased from 1.75 (baseline) to 3.75 (p < 0.05). The CVS criteria were not routinely used by the majority of participating surgeons. Further, one-fourth of those who claimed to obtain the CVS did so inadequately. All surgeons who participated in training showed improvement during their post-assessment. Our findings suggest that education of practicing surgeons in the application of the CVS during LC can result in increased implementation and quality of the CVS. Pending studies with larger samples, our findings may partly explain the sustained BDI incidence despite increased experience with LC. Our study also supports the value of direct observation of surgical practices and subsequent training for quality improvement.

Cultural effects on the association between election outcomes and face-based trait inferences.

Full Text Available How competent a politician looks, as assessed in the laboratory, is correlated with whether the politician wins in real elections. This finding has led many to investigate whether the association between candidate appearances and election outcomes transcends cultures. However, these studies have largely focused on European countries and Caucasian candidates. To the best of our knowledge, there are only four cross-cultural studies that have directly investigated how face-based trait inferences correlate with election outcomes across Caucasian and Asian cultures. These prior studies have provided some initial evidence regarding cultural differences, but methodological problems and inconsistent findings have complicated our understanding of how culture mediates the effects of candidate appearances on election outcomes. Additionally, these four past studies have focused on positive traits, with a relative neglect of negative traits, resulting in an incomplete picture of how culture may impact a broader range of trait inferences. To study Caucasian-Asian cultural effects with a more balanced experimental design, and to explore a more complete profile of traits, here we compared how Caucasian and Korean participants' inferences of positive and negative traits correlated with U.S. and Korean election outcomes. Contrary to previous reports, we found that inferences of competence (made by participants from both cultures correlated with both U.S. and Korean election outcomes. Inferences of open-mindedness and threat, two traits neglected in previous cross-cultural studies, were correlated with Korean but not U.S. election outcomes. This differential effect was found in trait judgments made by both Caucasian and Korean participants. Interestingly, the faster the participants made face-based trait inferences, the more strongly those inferences were correlated with real election outcomes. These findings provide new insights into cultural effects and the

2015-01-01

Many anesthesiologists are unfamiliar with the rate of surgical neurological complications of the shoulder and elbow procedures for which they provide local anesthetic-based anesthesia and/or analgesia. Part 1 of this narrative review series on neurological complications of elective orthopedic surgery describes the mechanisms and likelihood of peripheral nerve injury associated with some of the most common shoulder and elbow procedures, including open and arthroscopic shoulder procedures, elbow arthroscopy, and total shoulder and elbow replacement. Despite the many articles available, the overall number of studied patients is relatively low. Large prospective trials are required to establish the true incidence of neurological complications following elective shoulder and elbow surgery. As the popularity of regional anesthesia increases with the development of ultrasound guidance, anesthesiologists should have a thoughtful understanding of the nerves at risk of surgical injury during elective shoulder and elbow procedures.

Approximately 28% of the patients with cystic fibrosis are affected by cholelythiasis. More than 40% of them have a symptomatic disease, which would mandate cholecystectomy. The aim of this study was to review surgical and respiratory outcomes and quality of life scores of cystic fibrosis patients undergoing laparoscopic cholecystectomy for symptomatic cholelythiasis to verify the hypothesis that cholecystectomy is a low-risk operation by laparoscopy, not affecting unfavorably respiratory function and quality of life. Study group was consisted of 9 patients with a mean age of 24.8±8.1 years (range, 15 to 38 y), 2 male and 7 female patients, with cystic fibrosis and symptomatic cholelithiasis. Three patients also presented common bile duct stones. All the patients underwent perioperative Positive End-Expiratory Pressure mask sessions and aggressive antibiotic regimens. At the middle of the antibiotics regimen period, a standard laparoscopic cholecystectomy was performed. In the 3 cases with common duct lithiasis, the so-called "rendezvous" technique was carried out. Preoperatively, intraoperatively, and postoperatively, respiratory function was strictly monitored by the evaluation of SO2 and of the forced expiratory volume in 1 second (FEV1). Preoperatively and 6 months after laparoscopic cholecystectomy the Gastro Intestinal Quality of Life Index was evaluated on all patients. All the operations were completed laparoscopically. No mortality was observed. The intraoperative mean SO2 was 89.0%±5.6% (range, 80% to 95%), versus 82.8%±8.5% (range, 66% to 91%) at the extubation (P=0.006). Intraoperative respiratory functions were stable in 6 patients. In 3 patients, a severe bronchospasm occurred determining marked desaturation. Preoperative mean FEV1 was 70.5%±7.0% (range, 55% to 75%) versus 61.8%±13.2% (range, 39% to 80%) 48 hours after the operation (P=0.132). The 3 patients, who experienced intraoperatively severe bronchospasm, reported a 48 hours postoperative

A model for election night forecasting applied to the 2004 South African elections

Directory of Open Access Journals (Sweden)

JM Greben

2006-06-01

Full Text Available A novel model has been developed to predict elections on the basis of early results. The electorate is clustered according to their behaviour in previous elections. Early results in the new elections can then be translated into voter behaviour per cluster and extrapolated over the whole electorate. This procedure is of particular value in the South African elections which tend to be highly biased, as early results do not give a proper representation of the overall electorate. In this paper we explain the methodology used to obtain the predictions. In particular, we look at the different clustering techniques that can be used, such as kmeans, fuzzy clustering and k-means in combination with discriminant analysis. We assess the performances of the different approaches by comparing their convergence towards the final results.

The sampling characteristics of electivity indices.

Lechowicz, Martin J

1982-01-01

Electivity indices measure the utilization of food types (r) in relation to their abundance or availability in the environment (p). Foods that constitute a larger proportion of the diet than of the available foods are considered preferred; conversely those proportionately underrepresented in the diet are avoided. A food is eaten at random if its proportion in the diet equals its proportion in the environment. A family of electivity indices stemming from Ivlev's (1961) classic monograph exist and differ only in the particular algorithm used to calculate electivity from r and p.For each available index I graphed the values of electivity as contours for all combinations of r and p. These graphs are compared to illustrate the strengths and weaknesses of each index on the basis of the following criteria: 1) the value of the index when r=p for a food, 2) the symmetry of the electivity value as feeding deviates from random, 3) the possible range of index values, 4) the linearity of changes in electivity over the full range of r and p, 5) the sensitivity of the index to sampling errors, 6) the statistical testability of the electivity, and 7) the stability of the electivity value for a food type that changes relative abundance or occurs in combination with different food types. No one index ideally satisfies all the criteria.The host preferences of gypsy moth, Lymantria dispar, feeding on tree foliage in an undisturbed deciduous forest in southwestern Quebec, Canada were used to compare the available indices: Ivlev's electivity, E; Ivlev's forage ratio, E'; Jacob's modified electivity, D; Jacob's modified forage ratio, log Q; Chesson's alpha; Strauss' linear index, L; and Vanderploeg and Scavia's relativized electivity, E * . The electivity values calculated by each index differ one from another; host trees shown as preferred by one index will frequently appear avoided according to an alternative index. The rank order electivities for the 19 available host trees, however

EFFECT OF PREEMPTIVE MAGNESIUM SULPHATE ON PAIN RELIEF AFTER LAPAROSCOPIC CHOLECYSTECTOMY

2016-09-01

Full Text Available BACKGROUND The concept of preemptive analgesia was introduced by C. J. Woolf et al demonstrating that a post-injury hypersensitivity results via a central mechanism. The effect of magnesium on perioperative analgesic requirements was first evaluated by Koinig and his colleagues in patients with identical levels of surgical stimulation. Magnesium Sulphate is an antagonist of Nmethyl-D-aspartate (NMDA receptors and its associated channels and regulation of calcium influx into the cell. Magnesium causes modulation of acute pain reducing postsurgical pain intensity and dosage of analgesics. Seyhan et al have reported that magnesium sulphate boluses were effective for postoperative pain relief after gynaecological surgery. Fucs-Budder et al, Kussman B et al used continuous infusion (15 mg/kg/hr. in addition to initial bolus (50 mg/kg of magnesium sulphate in their studies, which caused bradycardia and delayed extubation time, which can be attributed to the infusion of Iva Bacak Kochman et al studied effect of low dose MgSO4 (7.5 mg/kg as analgesic agent after induction in patients undergoing laparoscopic cholecystectomy. This bolus dose of MgSO4 given for control of sympathetic response during intubation also reduced early postoperative pain. Study conducted by O Mentes et al on postoperative analgesic efficacy of single dose MgSO4 (50 mg/kg after laparoscopic cholecystectomy measured significantly less VAS scores. On this background, our study was done to evaluate the postoperative analgesic efficacy of single dose of magnesium sulphate (50 mg/kg as preemptive analgesic and measured after laparoscopic cholecystectomy. In addition to VAS scores, total tramadol consumption and time for first rescue analgesia, postoperative haemodynamic parameters and side effects if any were evaluated. METHODS After obtaining Institutional Ethical committee clearance and written informed consent from the patients, a randomised prospective study was conducted at King

Lyons, Jennifer L.; Coleman, Mary E.; Engstrom, John W.

2014-01-01

Objective: To ascertain the current status of global health training and humanitarian relief opportunities in US and Canadian postgraduate neurology programs. Background: There is a growing interest among North American trainees to pursue medical electives in low- and middle-income countries. Such training opportunities provide many educational and humanitarian benefits but also pose several challenges related to organization, human resources, funding, and trainee and patient safety. The current support and engagement of neurology postgraduate training programs for trainees to pursue international rotations is unknown. Methods: A survey was distributed to all program directors in the United States and Canada (December 2012–February 2013) through the American Academy of Neurology to assess the training opportunities, institutional partnerships, and support available for international neurology electives. Results: Approximately half of responding programs (53%) allow residents to pursue global health–related electives, and 11% reported that at least 1 trainee participated in humanitarian relief during training (survey response rate 61%, 143/234 program directors). Canadian programs were more likely to allow residents to pursue international electives than US programs (10/11, 91% vs 65/129, 50%, p = 0.023). The number of trainees participating in international electives was low: 0%–9% of residents (55% of programs) and 10%–19% of residents (21% of programs). Lack of funding was the most commonly cited reason for residents not participating in global health electives. If funding was available, 93% of program directors stated there would be time for residents to participate. Most program directors (75%) were interested in further information on global health electives. Conclusions: In spite of high perceived interest, only half of US neurology training programs include international electives, mostly due to a reported lack of funding. By contrast, the majority

Full Text Available Objective: to investigate the effects of preoperative fasting abbreviation with oral supplementation with carbohydrate in the evolution of grip strength in patients undergoing cholecystectomy by laparotomy. Methods : we conducted a clinical, randomizeddouble blind study with adult female patients, aged 18-60 years. Patients were divided into two groups: Control Group, with fasting prescription 6-8h until the time of operation; and Intervention Group, which received prescription of fasting for solids 6-8h before surgery, but ingested an oral supplement containing 12.5% carbohydrate, six (400ml and two (200ml hours before theprocedure. The handgrip strength was measured in both hands in both groups, at patient's admission (6h before surgery, the immediate pre-operative time (1h before surgery and 12-18h postoperatively. Results : we analyzed 27 patients, 14 in the intervention group and 13 in the control group. There was no mortality. The handgrip strength (mean [standard deviation] was significantly higher in the intervention group in the three periods studied, in at least one hand: preoperatively in the dominant hand (27.8 [2.6] vs 24.1 [3.7] kg; p=0.04, in the immediate preoperative in both hands, and postoperatively in the non-dominant hand (28.5 [3.0] vs 21.3 [5.9] kg; p=0.01. Conclusion : the abbreviation of preoperative fasting to two hours with drink containing carbohydrate improves muscle function in the perioperative period.

2017-11-01

Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2-3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose. Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included. Patients received a pre-operative questionnaire on medical history and social situation when informed consent on surgery and participation in the study was obtained. Exclusion criteria were patients suffering from acute cholecystitis or any type of cancer; having a BMI >40 kg/m 2 ; needing conversion to open cholecystectomy or an intraoperative drainage; and non-German speakers. Surgery was performed laparoscopically. Both surgeon and patient filled in a postoperative questionnaire. The surgeon's questionnaire listed medical and technical information, and the patients' questionnaire listed medical information, satisfaction with the treatment and willingness to be released on the same day. These data from both questionnaires were grouped into social and medical factors and analysed on their influence upon willingness to accept an ambulatory procedure. No outpatient follow-up apart from checking for readmission to our hospital within 1 month after discharge was performed. Of the 100 participants, one-third was male. More than two-thirds were Swiss citizens. Only one participant was ineligible for rapid release evaluation due to need of a drainage. Among the social factors contributing to the acceptability of ambulatory care, we found nationality to be relevant; Swiss citizens preferred an inpatient procedure, whereas non-Swiss citizens were significantly more willing to return home on the same day. Household size, sex and age did not correlate with a preference for

2016-09-01

Full Text Available BACKGROUND AND OBJECTIVE: One of the complications of laparoscopic cholecystectomy is trocar incision hernia (TSIH: Trocar Site Incisional Hernia, which occurs almost exclusively in the navel area and could cause significant problems. The aim of this study was to evaluate the prevalence of hiatal hernia in laparoscopic cholecystectomy and identify the associated risk factors. METHODS: This cross sectional study was done on patients who underwent laparoscopic cholecystectomy during one year in different hospitals of Babol. Information including age, gender, BMI, diagnosis prior to surgery, duration of hospitalization, duration of surgery, the thickness of the lining of the gallbladder, surgical site infection and umbilical hernia during 12 months follow-up for patients were confirmed and examined. FINDINGS: Among 270 studied patients, there were 236 women (87.4% and 34 men (12.59 %. Eleven patients (4.07% during the 12-month follow-up; they had a hiatal hernia surgical site infection in the navel area (223.82-4.33: CI-95%, OR: 31.14 and BMI (60.18-1.72 CI-95%; OR: 10.21 were associated with increased incidence of inguinal hernias. There was no relationship between other variables and umbilical hernia. CONCLUSION: According to the results of this study obesity and surgical site infections have been linked with an increased incidence of inguinal hernias.

The aim of this study is to compare the effects of intravenous single-dose dexketoprofen trometamol and diclofenac sodium 30 minutes before the end of the surgery on relief of postoperative pain in patients undergoing laparoscopic cholecystectomy. A randomized fashion. Sixty (American Society of Anesthesiologist class I-II) patients undergoing laparoscopic cholecystectomy were divided into 2 groups Patients in group DT received 50 mg dexketoprofen trometamol, whereas patients in group DS received 75 mg diclofenac sodium, intravenously 30 minutes before the end of surgery. Postoperative pain intensity, morphine consumption with patient-controlled analgesia, time to first analgesic requirement, complications, rescue analgesic (intravenous tenoxicam 20 mg) requirement, and duration of hospital stay were recorded. Postoperative pain visual analog scale scores were similar in the follow-up periods (P > .05). Patient-controlled analgesia morphine consumption was significantly less in group DT compared with group DS in all postoperative follow-up periods (2 and 4 hours: P dexketoprofen trometamol 30 minutes before the end of surgery provided effective analgesia with reduced consumption of opioids and requirement for rescue analgesic compared with diclofenac sodium in patients undergoing laparoscopic cholecystectomy. For this reason, we believe that, as a part of multimodal analgesia, dexketoprofen trometamol provides more effective analgesia than diclofenac sodium in patients undergoing laparoscopic cholecystectomy.

2010-01-01

We report a case of a woman who consulted for right upper quadrant abdominal pain with history of cholecystectomy six weeks ago. The ultrasound showed sub phrenic and peri hepatic nodular images, interpreted as biliary stones, confirmed with CT. Some of these nodules showed peripheral enhancement and suggested the presence of abscesses. The patient underwent surgery confirming the imaging findings. The case is very important for the role of imaging studies in the diagnostic approach of a surgical complication which has various clinical presentations that range from the absence of symptoms to a septic life-threatening disease.

The utility of laparoscopic repair in the treatment of incisional hernia repair is still contentious. The aim was to conduct a meta-analysis of RCTs investigating the surgical and postsurgical outcomes of elective incisional hernia by open versus laparoscopic method. A search of PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane Central Register of Controlled Trials published between January 1993 and September 2013 was performed using medical subject headings (MESH) "hernia," "incisional," "abdominal," "randomized/randomised controlled trial," "abdominal wall hernia," "laparoscopic repair," "open repair", "human" and "English". Prospective RCTs comparing surgical treatment of only incisional hernia (and not primary ventral hernias) using open and laparoscopic methods were selected. Data extraction and critical appraisal were carried out independently by two authors (AA and MAM) using predefined data fields. The outcome variables analyzed included (a) hernia diameter; (b) operative time; (c) length of hospital stay; (d) overall complication rate; (e) bowel complications; (f) reoperation; (g) wound infection; (h) wound hematoma or seroma; (i) time to oral intake; (j) back to work; (k) recurrence rate; and (l) postoperative neuralgia. These outcomes were unanimously decided to be important since they influence the practical and surgical approach towards hernia management within hospitals and institutions. The quality of RCTs was assessed using Jadad's scoring system. Random effects model was used to calculate the effect size of both binary and continuous data. Heterogeneity amongst the outcome variables of these trials was determined by the Cochran Q statistic and I (2) index. The meta-analysis was prepared in accordance with PRISMA guidelines. Sufficient data were available for the analysis of twelve clinically relevant outcomes. Statistically significant reduction in bowel complications was noted with open surgery compared to the

First experience with single incision laparoscopic surgery in Slovakia: concomitant cholecystectomy and splenectomy in an 11-year-old girl with hereditary spherocytosis.

Hereditary spherocytosis is an autosomal dominant inheritance disorder of the red blood cell membrane characterized by the presence of spherical-shaped erythrocytes (spherocytes) in the peripheral blood. The main clinical features include haemolytic anemia, variable jaundice, splenomegaly and cholelithiasis caused by hyperbilirubinemia from erythrocyte hemolysis. Splenectomy does not solve the congenital genetic defect but it stops pathological hemolysis in the enlarged spleen. If gallstones are present, it is appropriate to perform cholecystectomy at the time of splenectomy, although the patient has symptoms of gall bladder disease. We present the case of single incision laparoscopic surgical (SILS) concomitant splenectomy and cholecystectomy performed with conventional laparoscopic instruments in an 11-year-old girl with the diagnosis of hereditary spherocytosis. A 2-3 cm umbilical incision was used for the placement of two 5 mm trocars and one 10 mm flexible videoscope. Conventional laparoscopic dissector, grasper, Ligasure, Harmonic Ace and hemoclips were the main tools during surgical procedure. We prefer Single Incision Laparoscopic Surgery Foam Port (Covidien) as the single umbilical device for introduction into the abdominal cavity. First, we performed cholecystectomy, then the gallbladder was put aside over the liver and after that we peformed splenectomy. To remove the detached spleen and gallbladder, a nylon extraction bag is introduced through one of the port sites. The spleen is than morcellated in the bag with forceps and removed in fragments. After that we removed them and the umbilical fascial incision was closed. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Our experience shows that SILS splenectomy and cholecystectomy is feasible even in young children and

Introduction Patients with incidental pT2-T3 gallbladder cancer (IGC) after a cholecystectomy may benefit from a radical re-resection although their optimal treatment strategy is not well defined. In this Unit, such patients undergo delayed staging at 3 months after a cholecystectomy to assess the evidence of a residual tumour, extra hepatic spread and the biological behaviour of the tumour. The aim of this study was to evaluate the outcome of patients who had delayed staging at 3 months after a cholecystectomy. Methods From July 2003 to July 2011, 56 patients with T2-T3 gallbladder cancer were referred to this Unit of which 49 were diagnosed incidentally on histology after a cholecystectomy. All 49 patients underwent delayed pre-operative staging using multi-detector computed tomography (MDCT) followed selectively by laparoscopy at 3 months after a cholecystectomy. Data were collected from a prospectively held database. The peri-operative and long-term outcomes of patients were analysed. SPSS software was used for statistical analysis. Results There were 38 pT2 and 11 pT3 tumours. After delayed staging, 24/49 (49%) patients underwent a radical resection, 24/49 (49%) were found to be inoperable on pre-operative assessment and 1/49 (2%) patient underwent an exploratory laparotomy and were found to be unresectable. The overall median survival from referral was 20.7 months (54.8 months for the group who had a radical re-resection versus 9.7 months for the group who had unresectable disease, P < 0.001). These results compare favourably with the reported outcome of fast-track management for incidental pT2-T3 gallbladder cancer from other major series in the literature. Conclusion Delayed staging in patients with incidental T2-T3 gallbladder cancer after a cholecystectomy is a useful strategy to select patients who will benefit from a resection and avoid unnecessary major surgery.

This study was designed to compare spinal anesthesia using hyperbaric bupivacaine given as a conventional dose by lumbar puncture or as a low-dose by thoracic puncture.Methods: A total of 140 patients with symptomatic gallstone disease were randomized to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under spinal anesthesia using either conventional lumbar spinal anesthesia (hyperbaric bupivacaine 15 mg and fentanyl 20 mg or low-dose thoracic spinal anesthesia (hyperbaric bupivacaine 7.5 mg and fentanyl 20 µg. Intraoperative parameters, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two treatment groups.Results: All procedures were completed under spinal anesthesia, with no cases needing conversion to general anesthesia. Values for time for block to reach the T3 dermatomal level, duration of motor and sensory block, and hypotensive events were significantly lower with low-dose bupivacaine. Postoperative pain was higher for low-dose hyperbaric bupivacaine at 6 and 12 hours. All patients were discharged after 24 hours. Follow-up 1 week postoperatively showed all patients to be satisfied and to be keen advocates of spinal anesthesia.Conclusion: Laparoscopic cholecystectomy can be performed successfully under spinal anesthesia. A small dose of hyperbaric bupivacaine 7.5 mg and 20 µg fentanyl provides adequate spinal anesthesia for laparoscopy and, in comparison with hyperbaric bupivacaine 15% and fentanyl 20 µg, causes markedly

Bayesian inference on proportional elections.

Full Text Available Polls for majoritarian voting systems usually show estimates of the percentage of votes for each candidate. However, proportional vote systems do not necessarily guarantee the candidate with the most percentage of votes will be elected. Thus, traditional methods used in majoritarian elections cannot be applied on proportional elections. In this context, the purpose of this paper was to perform a Bayesian inference on proportional elections considering the Brazilian system of seats distribution. More specifically, a methodology to answer the probability that a given party will have representation on the chamber of deputies was developed. Inferences were made on a Bayesian scenario using the Monte Carlo simulation technique, and the developed methodology was applied on data from the Brazilian elections for Members of the Legislative Assembly and Federal Chamber of Deputies in 2010. A performance rate was also presented to evaluate the efficiency of the methodology. Calculations and simulations were carried out using the free R statistical software.

Nontechnical skills are an essential component of surgical education and a major competency assessed by the ACGME milestones project. However, the optimal way to integrate nontechnical skills training into existing curricula and then objectively evaluate the outcome is still unknown. The aim of this study was to determine the effect laparoscopic team-based task training would have on the nontechnical skills needed for laparoscopic surgery. 9 PGY-1 residents underwent an established training curriculum for teaching the knowledge and technical skills involved in laparoscopic cholecystectomy. Initial training involved a didactic session, expert-led practice on a porcine model in a simulated operating room and laparoscopic skills practice on a virtual reality trainer. Residents then performed a laparoscopic cholecystectomy on the same porcine model as a preintervention test. Three to four months following this, residents were subjected to specific nontechnical skills training involving 2 simple team-based laparoscopic tasks. They then practiced a further 4 to 6 hours on the virtual reality trainer. A repeat postintervention laparoscopic cholecystectomy was then performed 3 to 4 months after nontechnical skills training. Both the preintervention and postintervention laparoscopic cholecystectomies were audiovisually recorded and then evaluated by 2 independent surgeons in a blinded fashion. Technical skills were assessed using objective structured assessment of technical skills (OSATS) and a technique specific rating scale (TRS) that we developed for laparoscopic cholecystectomy. Nontechnical skills were assessed using nontechnical skills for surgeons (NOTSS). Residents also completed a survey at the beginning and end of the training. Tertiary care, university based teaching institution. A total of 9 general surgery residents at the intern level. The mean OSATS score improved from 13.7 ± 1.24 to 26.7 ± 0.31 (p training.

An increasing number of cardiac transplants are being carried out around the world. With increasing longevity, these patients present a unique challenge to non-transplant anesthesiologists for a variety of transplant related or incidental surgeries. The general considerations related to a cardiac transplant recipient are the physiological and pharmacological problems of allograft denervation, the side-effects of immunosuppression, the risk of infection and the potential for rejection. A thorough understanding of the physiology of a denervated heart, need for direct vasoactive agents and post-transplant morbidities is essential in anesthetic management of such a patient. Here, we describe a case of a heart transplant recipient who presented for a cholecystectomy at our center.

2012-01-01

Although patients with cholecystocholedocholithiasis are generally referred to cholecystectomy after endoscopic sphincterotomy (ES) and common bile duct clearance, we often have a conflict whether cholecystectomy is necessary in very elderly patients with comorbid diseases. The aim of this study is to assess whether cholecystectomy in very elderly patients is justified after ES. Patients with cholecystocholedocholithiasis who underwent ES and stone extraction and were followed-up for more than 10 years were retrospectively reviewed. We divided these patients into two groups: the elderly group (equal to or more than 80 years old) and young group (less than 80 years old) and compared late biliary complications and mortality. The 10-year cumulative incidence of overall biliary complications was significantly lower in cholecystectomized patients than in patients with gallbladder in situ in the young group (7.5 vs. 21.7%, p = 0.0037), but not different in the elderly group (8.3 vs. 7.4%, p = 0.92). When each complication was evaluated separately, the rate of recurrent common bile duct stones (CBDS) was not different, but that of acute cholecystitis was significantly lower in the elderly group than in the young group (4.1 vs. 22.6%, p = 0.011). In very elderly patients the incidence of acute cholecystitis is low even when the gallbladder is preserved after endoscopic treatment of CBDS, with a similar risk of CBDS recurrence. Thus, it may not be necessary to recommend cholecystectomy after ES for CBDS in very elderly patients.

Full Text Available Following initial regulatory approval of prescription drugs, many factors may influence insurers and health systems when they decide whether to add these drugs to their formularies. The role of political pressures on drug funding announcements has received relatively little attention, and elections represent an especially powerful form of political pressure. We examined the temporal relationship between decisions to add one class of drugs to publicly funded formularies in Canada's ten provinces and elections in these jurisdictions.Dates of provincial formulary listings for cholinesterase inhibitors, which are drugs used to treat Alzheimer's disease and related dementias, were compared to the dates of provincial elections. Medical journal articles, media reports, and proceedings from provincial legislatures were reviewed to assemble information on the chronology of events. We tested whether there was a statistically significant increase in the probability of drug funding announcements within the 60-day intervals preceding provincial elections.Decisions to fund the cholinesterase inhibitors were made over a nine-year span from 1999 to 2007 in the ten provinces. In four of ten provinces, the drugs were added to formularies in a time period closely preceding a provincial election (P = 0.032; funding announcements in these provinces were made between 2 and 47 days prior to elections. Statements made in provincial legislatures highlight the key role of political pressures in these funding announcements.Impending elections appeared to affect the timing of drug funding announcements in this case study. Despite an established structure for evidence-based decision-making, drug funding remains a complex process open to influence from many sources. Awareness of such influences is critical to maintain effective drug policy and public health decision-making.

Full Text Available Bartter′s syndrome is a rare inherited anamoly with defect in the thick segment of the ascending limb of the loop of Henle, with reduced reabsorption of potassium. Growth is affected with worsening renal function, hypokalaemia, hypochloraemic metabolic alkalosis, hypocalcemia, hypomagnesemia, increased levels of aldosterone, renin and angiotensin without hypertension and lack of responses to vasopressors. Treatment consists of potassium supplementation along with other medications. We present the case report, probably the first, of a child suffering from Bartter′s syndrome with gall stones posted for laparoscopic cholecystectomy. The pre-operative correction of hypokalemia and successful anaesthetic and fluid and electrolyte management of the patient are discussed.

Laparoscopic cholecystectomy (LC) actually represents the most used and proper treatment for gallbladder lithiasis, because its many and known advantages in comparison with 'open' abdominal surgery. But there are some problems during and after LC due to the use of the electric scalpel and these have brought to the search of an alternative system of dissection and coagulation. The ultrasonically activated scalpel (Harmonic Scalpel, HS) allows to perform dissection and coagulation with a minimal thermal side effect for surrounding tissues, unlike the electrocoagulation. Furthermore, the use of the HS brings a series of advantages in comparison to the other electromagnetic forms of energy (electro-scalpel, laser). HS cuts and coagulates with the same effectiveness of the electro-scalpel but, unlike this, it doesn't introduce risks of wandering currents. Moreover, HS contributes to have a more clean and clear (smokes-free) field of operation and it reduces the operative time, the bleeding and the costs of the operation without an increase of the complications and of the percentages of 'open' conversion, and perhaps leads to a less negative influence on the postoperative systemic immune response. The Authors report their experience that confirm these observations, according also with results reported in a brief review of the recent scientific literature, and support wider diffusion and technical development of this ultrasonically-operating surgical team.

A STUDY ON OPEN VS. LAPAROSCOPIC APPROACH IN ACUTE APPENDICITIS

Directory of Open Access Journals (Sweden)

Savalam Bujjitha

2016-05-01

Full Text Available Reginald Fitz in 1986, first described acute appendicitis. Since the acute appendicitis was first described, the pathology remains the most common intra-abdominal condition requiring emergency surgery. The life time risk of having acute appendicitis is about 8%. Traditionally, the treatment of choice has been surgery. Before the only option was the open laparotomical meaning opening the abdominal cavity was the mode of operation. Laparoscopic appendectomy was described by Semm in 1983. This method was new and had its own benefits but this particular procedure has struggled to prove its superiority over the open technique. This is contrast to laparoscopic cholecystectomy which has promptly become the gold standard for gallstone disease despite little scientific challenge. This peculiarity might be because of the fact that the Open Appendectomy was used for centuries with good effect. The particular procedure withstood the test of time for more than a century since its introduction by McBurney unlike cholecystectomy. Open surgery is typically completed using a small right lower quadrant incision between the point joining the lateral one-third and medial two-third of a line drawn from anterior-superior iliac spine and the umbilicus. The postoperative recovery is usually uneventful. The overall mortality of OA is around 0.3% and morbidity about 11%. Despite numerous randomised trials, several meta-analysis and systematic critical reviews, the clear cut winner is unannounced. A sincere effort has been put to understand the different pros and cons of the two methods so that the patient can be benefited. METHODS One Hundred cases were studied in the Department of Surgery, King George Hospital, Visakhapatnam, Andhra Pradesh from 01-09-2015 to 29-02-2016. Out of these, fifty cases underwent open surgery and the rest through laparoscopic surgery.

A prospective, randomized, double-blinded clinical study. Operating room, postoperative recovery area, and ward. In total, 60 laparoscopic cholecystectomy patients (43 women, 17 men, American Society of Anesthesiologists grades I-II) were enrolled from the general surgery department of our tertiary care center. The patients were assigned to 1 of the 3 groups. Group 1 received TAP blocks (n=20), group 2 received OSTAP blocks (n=20), and group 3 patients were used as controls and received patient-controlled analgesia (PCA) only (n=20). After the induction of anesthesia, blocks were performed bilaterally in study groups 1 and 2, using 20mL of lidocaine (5mg/mL). PCA with intravenous tramadol was routinely provided for all patients during the first 24hours. The intraoperative use of remifentanil, postoperative visual analog scale (VAS) scores, demand for PCA, and total analgesic consumption were recorded. The patients in the control group had greater analgesic demands and analgesic consumption than did those in groups 1 and 2. However, patients in the OSTAP group had lower VAS scores than did those in groups 1 and 3. The demand for analgesia was greater in the control group than in groups 1 and 2. Moreover, lower VAS scores were recorded in the OSTAP group than in groups 1 and 3 and were positively correlated with total PCA consumption among all patients. However, postoperative VAS scores were negatively correlated with the total intraoperative consumption of remifentanil at 24hours. TAP and OSTAP blocks improved postoperative analgesia in patients receiving laparoscopic cholecystectomy, which resulted in lower VAS scores and reduction in total analgesic consumption.

We propose a portable fluorescence microscopic imaging system (PFMS) for intraoperative display of biliary structure and prevention of iatrogenic injuries during cholecystectomy. The system consists of a light source module, a camera module, and a Raspberry Pi computer with an LCD. Indocyanine green (ICG) is used as a fluorescent contrast agent for experimental validation of the system. Fluorescence intensities of the ICG aqueous solution at different concentration levels are acquired by our PFMS and compared with those of a commercial Xenogen IVIS system. We study the fluorescence detection depth by superposing different thicknesses of chicken breast on an ICG-loaded agar phantom. We verify the technical feasibility for identifying potential iatrogenic injury in cholecystectomy using a rat model in vivo. The proposed PFMS system is portable, inexpensive, and suitable for deployment in resource-limited settings.

Electing Not to Fight: Elections as a Mechanism of Deradicalisation after the Irish Civil War 1922–1938

Directory of Open Access Journals (Sweden)

Bill Kissane

2012-05-01

Full Text Available Much research into the relationship between democratisation and conflict argues that holding elections soon after civil war, when nationalist issues still resonate, is likely to see voters elect to fight. This paper explores a case where elections had the opposite effect. Examination of the relationship between election results and political developments, as well as geographical voting patterns, demonstrates that elections were the primary mechanism for the deradicalisation of Irish politics after the civil war of 1922–23. Elections served as a mechanism for arbitration, selection, and coordination between more and less radical elites and their bases of support. Once the new state had shown its strength it had to accommodate gradual change, while electoral losers had to show they could reconcile change with stability. Elections helped establish credibility in both respects without altering the state-society relationship, suggesting that deradicalisation was dependent on state performance, and thus on some shared conception of the state. This combination of credibility, electoral legitimacy, and state performance, enabled a revolutionary elite, schooled in both constitutional and revolutionary politics, to deradicalise Irish nationalism after independence.

In 2009, the NHS evidence adoption center and National Institute for Health and Care Excellence (NICE) published a review of the use of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs). They recommended the development of a risk-assessment tool to help identify AAA patients with greater or lesser risk of operative mortality and to contribute to mortality prediction.A low anaerobic threshold (AT), which is a reliable, objective measure of pre-operative cardiorespiratory fitness, as determined by pre-operative cardiopulmonary exercise testing (CPET) is associated with poor surgical outcomes for major abdominal surgery. We aimed to assess the impact of a CPET-based risk-stratification strategy upon perioperative mortality, length of stay and non-operative costs for elective (open and endovascular) infra-renal AAA patients. A retrospective cohort study was undertaken. Pre-operative CPET-based selection for elective surgical intervention was introduced in 2007. An anonymized cohort of 230 consecutive infra-renal AAA patients (2007 to 2011) was studied. A historical control group of 128 consecutive infra-renal AAA patients (2003 to 2007) was identified for comparison.Comparative analysis of demographic and outcome data for CPET-pass (AT ≥ 11 ml/kg/min), CPET-fail (AT 11 ml/kg/min was associated with reduced perioperative mortality (open cases only), LOS, survival and inpatient costs (open and endovascular repair) for elective infra-renal AAA surgery.

Laparoscopic completion radical cholecystectomy for T2 gallbladder cancer.

Science.gov (United States)

Gumbs, Andrew A; Hoffman, John P

2010-12-01

The role of minimally invasive surgery in the surgical management of gallbladder cancer is a matter of controversy. Because of the authors' growing experience with laparoscopic liver and pancreatic surgery, they have begun offering patients laparoscopic completion partial hepatectomies of the gallbladder bed with laparoscopic hepatoduodenal lymphadenectomy. The video shows the steps needed to perform laparoscopic resection of the residual gallbladder bed, the hepatoduodenal lymph node nodes, and the residual cystic duct stump in a setting with a positive cystic stump margin. The skin and fascia around the previous extraction site are resected, and this site is used for specimen retrieval during the second operation. To date, three patients have undergone laparoscopic radical cholecystectomy with hepatoduodenal lymph node dissection for gallbladder cancer. The average number of lymph nodes retrieved was 3 (range, 1-6), and the average estimated blood loss was 117 ml (range, 50-200 ml). The average operative time was 227 min (range, 120-360 min), and the average hospital length of stay was 4 days (range, 3-5 days). No morbidity or mortality was observed during 90 days of follow-up for each patient. Although controversy exists as to the best surgical approach for gallbladder cancer diagnosed after routine laparoscopic cholecystectomy, the minimally invasive approach seems feasible and safe, even after previous hepatobiliary surgery. If the previous extraction site cannot be ascertained, all port sites can be excised locally. Larger studies are needed to determine whether the minimally invasive approach to postoperatively diagnosed early-stage gallbladder cancer has any drawbacks.

Although simulation-based training allows residents to become proficient in surgical skills outside the OR, residents still depend on senior surgeons' guidance in transferring skills accumulated from simulators into the operating room. This study aimed to identify and classify explicit instructions made by attending surgeons to their residents during laparoscopic surgery. Through these instructions, we examined the role gaze guidance plays in OR-based training. A total of ten laparoscopic cholecystectomy cases being performed by PGY4 residents were analyzed. The explicit directional instructions given by the mentoring attending surgeons to their residents were identified and classified into four categories based on their locations in the coordinate system. These categories were further combined into two classes, based on the target of instructions. The frequencies of instructions in the two classes were compared, and effect size was calculated. There were 1984 instructions identified in the ten cases. The instructions were categorized into instrument guidance (38.51%) and gaze guidance (61.49%). The instrument guidance focused on moving the instruments to perform surgical tasks, including directions to targets, instrument manipulation, and instrument interaction. The gaze guidance focused on achieving common ground during the operation, including target identification and target fixation. The frequency of gaze guidance is significantly higher than instrument guidance in a laparoscopic cholecystectomy (p guidance has become the main focus of OR-based training. The results show a tight connection between adopting expert gaze and performing surgical tasks and suggest that gaze training should be integrated into the simulation training.

Preoperative oral dextromethorphan does not reduce pain or morphine consumption after open cholecystectomy

Directory of Open Access Journals (Sweden)

Mahmoodzadeh Hossein

2009-01-01

Full Text Available Background: Dextromethorphan, the D-isomer of the codeine analog levorphanol, is a weak, noncompetitive N-Methyl-D-Aspartate (NMDA receptor antagonist. It has been suggested that NMDA receptor antagonists induce preemptive analgesia when administered before tissue injury occurs, thus decreasing the subsequent sensation of pain. Materials and Methods: The study was conducted in the Dr. Ali Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran, between February 2005 and December 2006. In this study, 72 patients scheduled for elective cholesyctectomy were randomized into three groups to receive either oral dextromethorphan 45 mg (Group D45 = 24, dextromethorphan 90 mg (Group D90 = 24, or placebo (Group C, n = 24, as premedication, 120 minutes before surgery. A visual analog scale (VAS for pain of each patient was measured at arrival in the ward and six and 24 hours after surgery. Results: The demographic characteristics of patients, ASA physical status class, duration of surgery, and the basal VAS pain score were similar in the two groups. There was no significant difference in the mean of the VAS pain scores measured over time or morphine consumption among the three groups. Conclusion: Dextromethorphan 45 mg and 90 mg, administrated orally, two hours before surgery, had no effect on postoperative morphine requirement and pain intensity.

2010-03-01

Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique that aims at reducing or abolishing skin incisions and potentially also postoperative pain. The purpose of this study was to analyse operative and long-term results of a series of hybrid transvaginal cholecystectomy. Between July 2007 and May 2009, transvaginal NOTES cholecystectomy for symptomatic cholelithiasis was performed by a hybrid technique in 18 women (mean age 54 years), including four women with a body mass index >30 kg/m(2). Dissection was conducted in the first four cases by a round-tip unipolar electrode (UE) introduced through the operative channel of the endoscope coming from the vagina and in the last 14 cases by a ultrasonic scalpel (US) introduced through a 5-mm abdominal port. The short-term outcomes and the long-term results of the two methods were compared. The transvaginal approach entailed no intraoperative complication and no conversion. The overall mean duration of procedures was 75 min (range 40-190). In the first four cases (UE), the operating time was 148 min (range 140-190), whilst in the last 14 (US), it was considerably shorter, 53 min (range 40-60, p < 0.01). We experienced one biliary leak in the UE group, whilst morbidity with US was nil (p < 0.005). The biliary leak healed in 7 days with nasobiliary drainage. No other complications were encountered in either group. The mean follow-up was 12 months (range 1-22), and none of the patients has complained of dyspareunia or other colpotomy-related complications so far. Until specifically designed endoscopic tools are available for NOTES, the hybrid technique with US dissection conducted through a 5-mm port should be preferred in transvaginal cholecystectomy in order to shorten the duration of surgery and make this approach effective, safe and reproducible. After a mean follow-up of 1 year, none of our patients has complained of any problem related to transvaginal approach.

The Role of Volunteers and Political Participation in the 2012 Jakarta Gubernatorial Election

Directory of Open Access Journals (Sweden)

Ahmad Suaedy

2014-01-01

Full Text Available The changes that occurred in the Jakarta 2012 election may be seen as a change in Indonesia’s social movements and election tradition. They marked a social movement with special characteristics; specifically, a ‘partisan’ movement, led by the successful Jokowi–Ahok ticket. The partisan social movement also changed the tradition of money politics, which has always coloured general and local elections in Indonesia. This paper found four main factors in Jokowi–Ahok’s victory. The first was their reputations and track records of leadership and consistency, which, secondly, encouraged unpaid volunteers to motivate the public to participate in the election and vote for the pair. Thirdly, in contrast to previous social movements in Indonesia, the volunteers did not just work to overthrow the current leadership and replace it, and then distance themselves, but instead continued to monitor the candidates; some managed government directly, while others took watch dog position. Fourthly, the relationship between volunteers and local government was not necessarily oppositional. As such, they were partisan not only in that they were supporters of a pair of candidates, but also in their promotion and support of openness, anti-corruption efforts and provision of maximum public services.

Successful outcome of sphincterotomy and 7 French pigtail stent insertion in the management of post-cholecystectomy bile leaks.

LENUS (Irish Health Repository)

Donnellan, Fergal

2009-06-01

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is widely used to manage post-cholecystectomy bile leaks. However, the best endoscopic intervention remains controversial. We investigated the success of a 7 French double pigtail stent following sphincterotomy in the management of such bile leaks. METHODS: Between July 1998 and June 2008, 48 patients were referred for ERCP for presumed post-cholecystectomy bile leaks. Leaks were confirmed at ERCP and managed by a combination of sphincterotomy and stent insertion unless contraindicated. RESULTS: Bile duct cannulation was successful in 44 (91.7%) patients. A leak of the cystic duct was demonstrated in 19 (43.2%) patients, the duct of Luschka in 11 (25.0%), and the common hepatic duct in 5 (11.4%). Complete transection of the common bile duct occurred in 4 patients. The remaining patients had no cholangiographic evidence of a leak. Sphincterotomy was performed in 34 patients. A 7 French double pigtail plastic stent was placed in all 35 patients with cholangiographic evidence of a bile leak. No bile leaks were demonstrated at a follow-up of 8-16 weeks and all stents were removed successfully. CONCLUSION: The combination of sphincterotomy and insertion of a 7 French double pigtail stent results in excellent outcomes in the management of post-cholecystectomy bile leaks.

2015-01-01

Global Operative Assessment of Laparoscopic Skills (GOALS) assessment has been designed to evaluate skills in laparoscopic surgery. A longitudinal blinded study of randomized video fragments was conducted to estimate the validity and reliability of GOALS in novice trainees. In total, 10 trainees each performed 6 consecutive laparoscopic cholecystectomies. Sixty procedures were recorded on video. Video fragments of (1) opening of the peritoneum; (2) dissection of Calot's triangle and achievement of critical view of safety; and (3) dissection of the gallbladder from the liver bed were blinded, randomized, and rated by 2 consultant surgeons using GOALS. Also, a grade was given for overall competence. The correlation of GOALS with live observation Objective Structured Assessment of Technical Skills (OSATS) scores was calculated. Construct validity was estimated using the Friedman 2-way analysis of variance by ranks and the Wilcoxon signed-rank test. The interrater reliability was calculated using the absolute and consistency agreement 2-way random-effects model intraclass correlation coefficient. A high correlation was found between mean GOALS score (r = 0.879, p = 0.021) and mean OSATS score. The GOALS score increased significantly across the 6 procedures (p = 0.002). The trainees performed significantly better on their sixth when compared with their first cholecystectomy (p = 0.004). The consistency agreement interrater reliability was 0.37 for the mean GOALS score (p = 0.002) and 0.55 for overall competence (p < 0.001) of the 3 video fragments. The validity observed in this randomized blinded longitudinal study supports the existing evidence that GOALS is a valid tool for assessment of novice trainees. A relatively low reliability was found in this study. Copyright © 2014 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

medio del test t de Student conjugado. EL valor de p BACKGROUND AND OBJECTIVES: Upper abdominal surgeries may cause postoperative respiratory dysfunction. The objective of this study was to evaluate the pulmonary function after laparoscopic and open cholecystectomies, with and without epidural morphine. METHODS: In this randomized, double-blind clinical trial, 45 patients undergoing cholecystectomies were divided in three groups: GL, GA, and GAM, composed of 15 patients each. The GL group underwent laparoscopic surgery, while GA and GAM underwent open cholecystectomy, but the former received epidural morphine. Pre- and postoperative spirometry and arterial blood gases were performed. ANOVA was used to verify the hypothesis of equality of the means among the groups. When results were statistically significant, the Tukey test was performed. Paired test t Student was used to verify the hypothesis of equality within a group. A p < 0.05 was considered significant. RESULTS: The pre and immediately postoperative spirometry results were used to determine: a forced vital capacity (FVC in GL versus GA (p = 0.000 and GL versus GAM (p = 0.000; percentage of the reduction of FVC in GA versus GAM (p = 0.001; b within each group: in GL, FVC (p = 0.020 and forced expiratory volume in 1 second (FEV1 (p = 0.022; in GA, FVC (p < 0.001 and FEV1 (p < 0.001; and in GAM, FVC (p = 0.007 and FEV1 (p = 0.001. The arterial oxygen pressure (PaO2 was reduced in all three groups. CONCLUSIONS: One can conclude that respiratory dysfunction was less severe in patients operated by laparoscopy and that epidural morphine reversed, partially, the postoperative ventilatory disturbances of open cholecystectomy.

Laparoscopic cholecystectomies are associated with an appreciably high rate of postoperative nausea and vomiting (PONV). This study was designed to compare the effectiveness of ondansetron, granisetron, and dexamethasone for the prevention of PONV in patients after laparoscopic cholecystectomy. A total of 80 American Society of Anesthesiologists (ASA) physical class I-II patients scheduled for laparoscopic cholecystectomy were included in this randomized, double blind, placebo-controlled study. All patients received a similar standardized anesthesia and operative treatment. Patients were randomly divided into four groups (n = 20 each). Group 1, consisting of control patients, received 0.9% NaCl; group 2 patients received ondansetron 4 mg i.v.; group 3 patients received granisetron 3 mg i.v.; and group 4 patients received dexamethasone 8 mg i.v., all before the induction of anesthesia. Both nausea and vomiting were assessed during the first 24 h after the procedure. The total incidence of PONV was 75% with placebo, 35% with ondansetron, 30% with granisetron, and 25% with dexamethasone. The incidence of PONV was significantly less frequent in groups receiving antiemetics (p granisetron, and ondansetron were not significant. Prophylactic dexamethasone 8 mg i.v. significantly reduced the incidence of PONV in patients undergoing laparoscopic cholecystectomy. Dexamethasone 8 mg was as effective as ondansetron 4 mg and granisetron 3 mg, and it was more effective than placebo.

The purpose of this study was to prospectively compare the clinical applicability of magnetic resonance cholangiography (MRC) with that of endoscopic retrograde cholangiography (ERC) in the evaluation of combined choledocholithiasis in patients with gall stones who were candidates for laparoscopic cholecystectomy. Twenty-seven patients with gall stones underwent fast spin-echo MR cholangiography using the half-Fourier acquisition single-shot turbo spin echo (HASTE) method, and half-Fourier rapid acquisition using the relaxation enhancement (RARE) method. Within five hours the same patients underwent ERC. The results of MRC was reviewed by two radiologists blinded to the results of ERC. The number and size of CBD stones and gall stones, and the degree of CBD dilatation, as seen on HASTE and RARE images, were compared with the results of ERC. MRC depicted common bile duct stones in 10 of 11 patients shown by ERC to have stones, while in the 16 patients in whom ERC did not reveal stones, MRC demonstrated the same finding. The number of CBD stones was exactly demonstrated by HASTE imaging in eight of eleven patients (73%) and by RARE imaging in ten of eleven patients (91%) in whom ERC revealed choledocholithiasis. The size of common bile duct stones visualized by ERC correlated in nine of eleven patients (82%) on HASTE images and in seven of eleven (64%) on RARE images. MRC showed CBD dilatation in all patients in whom dilatation was demonstrated by ERC. For the evaluation of choledocholithiasis before laparoscopic cholecystectomy in patients with gall stones, MRC and ERC are equally accurate. A comparison of HASTE imaging with RARE imaging, as used in the diagnosis of choledocholithiasis, revealed no significant differences. (author)

Sujka, Joseph A; Safcsak, Karen; Bhullar, Indermeet S; Havron, William S

2018-01-30

To determine if pager interruptions affect operative time, safety, or complications and management of pager issues during a simulated laparoscopic cholecystectomy. Twelve surgery resident volunteers were tested on a Simbionix Lap Mentor II simulator. Each resident performed 6 randomized simulated laparoscopic cholecystectomies; 3 with pager interruptions (INT) and 3 without pager interruptions (NO-INT). The pager interruptions were sent in the form of standardized patient vignettes and timed to distract the resident during dissection of the critical view of safety and clipping of the cystic duct. The residents were graded on a pass/fail scale for eliciting appropriate patient history and management of the pager issue. Data was extracted from the simulator for the following endpoints: operative time, safety metrics, and incidence of operative complications. The Mann-Whitney U test and contingency table analysis were used to compare the 2 groups (INT vs. NO-INT). Level I trauma center; Simulation laboratory. Twelve general surgery residents. There was no significant difference between the 2 groups in any of the operative endpoints as measured by the simulator. However, in the INT group, only 25% of the time did the surgery residents both adequately address the issue and provide effective patient management in response to the pager interruption. Pager interruptions did not affect operative time, safety, or complications during the simulated procedure. However, there were significant failures in the appropriate evaluations and management of pager issues. Consideration for diversion of patient care issues to fellow residents not operating to improve quality and safety of patient care outside the operating room requires further study. Copyright © 2018.

We investigated 58 cases of cholecystolithiasis including 8 cases of choledocholithiasis treated with laparoscopic cholecystectomy. All patients received spiral CT scanning with drip infusion cholangiography (DIC-SCT), and 16 patients received endoscopic retrograde cholangiography (ERC), and the detection rates of the gallbladder, the bile duct and the cystic duct were compared. The gallbladder could be seen in 86.2% of cases with DIC-SCT and in 63.8% of cases with conventional DIC. The junction between the cystic duct and the common bile duct could be seen in 18 of 58 cases with DIC and in 49 of 58 cases with DIC-SCT. The DIC-SCT showed significantly superior anatomical datails compared with images with conventional DIC. A comparison of DIC, ERC and DIC-SCT revealed that the junction between the cystic duct and the common bile duct could be identified in 14 of 16 cases undergoing ERC, in 13 of 16 cases receiving DIC-SCT and in 4 of 16 cases receiving DIC. Significant differences were noted among DIC-SCT, ERC and conventional DIC. We concluded that DIC-SCT is easy, non-invasive and useful for the preoperative assessment of laparoscopic cholecystectomy and also helpful for avoiding damage to the bile duct. (author)

Full Text Available Objectives. We report the single-incision laparoscopic cholecystectomy (SILC learning experience of 2 hepatobiliary surgeons and the factors that could influence the learning curve of SILC. Methods. Patients who underwent SILC by Surgeons A and B were studied retrospectively. Operating time, conversion rate, reason for conversion, identity of first assistants, and their experience with previous laparoscopic cholecystectomy (LC were analysed. CUSUM analysis is used to identify learning curve. Results. Hundred and nineteen SILC cases were performed by Surgeons A and B, respectively. Eight cases required additional port. In CUSUM analysis, most conversion occurred during the first 19 cases. Operating time was significantly lower (62.5 versus 90.6 min, P = 0.04 after the learning curve has been overcome. Operating time decreases as the experience increases, especially Surgeon B. Most conversions are due to adhesion at Calot’s triangle. Acute cholecystitis, patients’ BMI, and previous surgery do not seem to influence conversion rate. Mean operating times of cases assisted by first assistant with and without LC experience were 48 and 74 minutes, respectively (P = 0.004. Conclusion. Nineteen cases are needed to overcome the learning curve of SILC. Team work, assistant with CLC experience, and appropriate equipment and technique are the important factors in performing SILC.

Full Text Available Background. Intraperitoneal nebulization of ropivacaine reduces postoperative pain and morphine consumption after laparoscopic surgery. The aim of this multicenter double-blind randomized controlled trial was to assess the efficacy of different doses and dose-related absorption of ropivacaine when nebulized in the peritoneal cavity during laparoscopic cholecystectomy. Methods. Patients were randomized to receive 50, 100, or 150 mg of ropivacaine 1% by peritoneal nebulization through a nebulizer. Morphine consumption, pain intensity in the abdomen, wound and shoulder, time to unassisted ambulation, discharge time, and adverse effects were collected during the first 48 hours after surgery. The pharmacokinetics of ropivacaine was evaluated using high performance liquid chromatography. Results. Nebulization of 50 mg of ropivacaine had the same effect of 100 or 150 mg in terms of postoperative morphine consumption, shoulder pain, postoperative nausea and vomiting, activity resumption, and hospital discharge timing (>0.05. Plasma concentrations did not reach toxic levels in any patient, and no significant differences were observed between groups (P>0.05. Conclusions. There is no enhancement in analgesic efficacy with higher doses of nebulized ropivacaine during laparoscopic cholecystectomy. When administered with a microvibration-based aerosol humidification system, the pharmacokinetics of ropivacaine is constant and maintains an adequate safety profile for each dosage tested.

Full Text Available 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.

Full Text Available Background: The study was designed to compare the effect of intraincisional vs intraperitoneal infiltration of levobupivacaine 0.25% on post-operative pain in laparoscopic cholecystectomy. Materials and Methods: This randomised controlled study was carried out on 189 patients who underwent laparoscopic cholecystectomy. Group 1 was the control group and did not receive either intraperitoneal or intraincisional levobupivacaine. Group 2 was assigned to receive local infiltration (intraincisional of 20 ml solution of levobupivacaine 0.25%, while Group 3 received 20 ml solution of levobupivacaine 0.25% intraperitoneally. Post-operative pain was recorded for 24 hours post-operatively. Results: Post-operative abdominal pain was significantly lower with intraincisional infiltration of levobupivacaine 0.25% in group 2. This difference was reported from 30 minutes till 24 hours post-operatively. Right shoulder pain showed significantly lower incidence in group 2 and group 3 compared to control group. Although statistically insignificant, shoulder pain was less in group 3 than group 2. Conclusion: Intraincisional infiltration of levobupivacaine is more effective than intraperitoneal route in controlling post-operative abdominal pain. It decreases the need for rescue analgesia.

We aimed to investigate whether students at German medical schools participating in elective courses on acupuncture and homeopathy differ from an unselected group of students regarding attitudes and personality traits. Elective courses on acupuncture and homeopathy in the academic half-year 2013/14 all over Germany were identified and participants invited to fill in a questionnaire including nineteen questions on attitudes towards Complementary and Alternative Medicine (CAM), orientation towards science, care and status orientation, and a short validated instrument (Big-Five-Inventory-10) to measure personality traits (extraversion, neuroticism, openness, conscientiousness, and agreeableness). Participants of a mandatory family medicine course at one university served as unselected control group. Two hundred twenty and 113 students from elective courses on acupuncture and homeopathy, respectively, and 315 control students participated (response rate 93%). Students participating in elective courses had much more positive attitudes towards CAM, somewhat lower science and status orientation, and somewhat higher care orientation than control group students (all p-values for three-group comparisons homeopathy at German medical schools differ to a considerable degree from the attitudes of unselected students.

2013-01-01

Full Text Available Background/Aim: Laparoscopic cholecystectomy is considered to be the gold standard for laparoscopic surgical procedures. In ASA III patients with concomitant respiratory diseases, however, creation of pneumoperitoneum and the position of patients during surgery exert additional negative effect on intraoperative respiratory function, thus making a higher challenge for the anesthesiologist than for the surgeon. The aim of this study was to compare the effect of intermittent positive pressure ventilation (IPPV and pressure controlled ventilation (PCV during general anesthesia on respiratory function in ASA III patients submitted to laparoscopic cholecystectomy. Methods. The study included 60 patients randomized into two groups depending on the mode of ventilation: IPPV or PCV. Respiratory volume (VT, peak inspiratory pressure (PIP, compliance (C, end-tidal CO2 pressure (PETCO2, oxygen saturation (SpO2, partial pressures of O2, CO2 (PaO2 and PaCO2 and pH of arterial blood were recorded within four time intervals. Results. There were no statistically significant differences in VT, SpO2, PaO2, PaCO2 and pH values neither within nor between the two groups. In time interval t1 there were no statistically significant differences in PIP, C, PETCO2 values between the IPPV and the PCV group. But, in the next three time intervals there was a difference in PIP, C, and PETCO2 values between the two groups which ranged from statistically significant to highly significant; PIP was lower, C and PETCO2 were higher in the PCV group. Conclusion. Pressure controlled ventilation better maintains stability regarding intraoperative ventilatory parameters in ASA III patients with concomitant respiratory diseases during laparoscopic cholecystectomy.

Full Text Available In the following article the author covers the process of counting the votes and the disclosure rules of establishment the election results in the Swiss Confederation. Switzerland along with other EU member states pays special attention to the determination of the election results. According to Art. 149 para. 2 Federal Constitution of the Swiss Confederation the elections to the National Council, which is one of two chambers of the Federal Assembly, are held according to proportional representation system. The Hagenbach-Bischoff system is used for allocating seats in National Council of the Swiss Con federation. However the above mentioned system for determining the quota of votes per each mandate creates ambiguous opinions among Swiss scientists and legal experts, which frequently comes up in discussions whether to modify it or not. In this article, the author also gives a brief description of the main political parties in Switzerland and statistics of seats allocation in 49 legislature of National Council following the elections of October 23, 2011. As a result, the author provides the full information on the process of votes counting and establishment of election results in the Swiss Confederation. The material presented in this article is particularly interesting and relevant in terms of improving the electoral legislation in the Russian Federation. The information presented by the author will be useful to all parties interested in electoral law.

2012-01-01

Full Text Available Background: Pain experienced following laparoscopic cholecystectomy is largely contributed by the anterior abdominal wall incisions. This study investigated whether subcostal transversus abdominis (STA block was superior to traditional port-site infiltration of local anesthetic in reducing postoperative pain, opioid consumption, and time for recovery. Materials and Methods: Forty-three patients presenting for day case laparoscopic cholecystectomy were randomly allocated to receive either an ultrasound-guided STA block (n = 21 or port-site infiltration of local anesthetic (n = 22. Visual analog pain scores were measured at 1 and 4 h postoperatively to assess pain severity, and opioid requirement was measured in recovery and up to 8 h postoperatively. The time to discharge from recovery was recorded. Results: STA block resulted in a significant reduction in serial visual pain analog score values and significantly reduced the fentanyl requirement in recovery by >35% compared to the group that received local port-site infiltration (median 0.9 vs. 1.5 ΅cg/kg. Furthermore, STA block was associated with nearly a 50% reduction in overall 8-h equivalent morphine consumption (median 10 mg vs. 19 mg. In addition, STA block significantly reduced median time to discharge from recovery from 110 to 65 min. Conclusion: The results suggest that STA block provides superior postoperative analgesia and reduces opioid requirement following laparoscopic cholecystectomy. It may also improve theater efficiency by reducing time to discharge from the recovery unit.

Natural Orifice Transluminal Endoscopic Surgery (NOTES) provides an emerging surgical technique which usually needs a long learning curve for surgeons. Virtual reality (VR) medical simulators with vision and haptic feedback can usually offer an efficient and cost-effective alternative without risk to the traditional training approaches. Under this motivation, we developed the first virtual reality simulator for transvaginal cholecystectomy in NOTES (VTEST™). This VR-based surgical simulator aims to simulate the hybrid NOTES of cholecystectomy. We use a 6DOF haptic device and a tracking sensor to construct the core hardware component of simulator. For software, an innovative approach based on the inner-spheres is presented to deform the organs in real time. To handle the frequent collision between soft tissue and surgical instruments, an adaptive collision detection method based on GPU is designed and implemented. To give a realistic visual performance of gallbladder fat tissue removal by cautery hook, a multi-layer hexahedral model is presented to simulate the electric dissection of fat tissue. From the experimental results, trainees can operate in real time with high degree of stability and fidelity. A preliminary study was also performed to evaluate the realism and the usefulness of this hybrid NOTES simulator. This prototyped simulation system has been verified by surgeons through a pilot study. Some items of its visual performance and the utility were rated fairly high by the participants during testing. It exhibits the potential to improve the surgical skills of trainee and effectively shorten their learning curve. Copyright © 2016 Elsevier Inc. All rights reserved.

Objective: To evaluate and compare the effects of pre-operative single oral dose of tramadol and famotidine on gastric secretions pH and volume in patients electively scheduled for laparoscopic cholecystectomy. Study Design: Randomized control trial. Place and Duration of Study: Department of Anaesthesia, King Saud University Riyadh, Saudi Arabia, from August 2011 to June 2013. Methodology: Ninety adult, ASA-I and II patients scheduled for laparoscopic cholecystectomy were included in the study. Patients were randomly assigned to receive pre-operatively either placebo (Group-C, n=30), oral tramadol 100 mg (Group-T, n=30) or famotidine 40 mg (Group-F, n=30). After induction of general anaesthesia, gastric fluid was aspirated through orogastric tube. The gastric secretions volume and pH was measured using pH meter. Results:There was no statistically difference between groups in age, weight and gender. The gastric secretions mean pH was 2.06 ± 0.22,2.04 ± 0.20, 5.79 ± 0.77 and volume was 0.59 ± 0.17, 0.59 ± 0.14 and 0.28 ± 0.16 ml/kg in Group-C, Group-T and Group-F respectively. There was a significant statistical difference in the mean pH values between Group-C vs. Group-F (p greater than 0.001) and Group-Tvs. Group-F (p greater than 0.001). Statistically significant difference was also found in the mean gastric secretions volume between Group - C vs. Group-F (p greater than 0.001) and Group-Tvs. Group-F (p greater than 0.001). There was no significant difference in the mean gastric fluid pH values (p=0.99) and mean gastric secretions volume (p=0.99) between Group-Tand Group-C. Conclusion:As compared to famotidine, pre-operative single oral dose of tramadol was unable to elevate the desired level of gastric fluid pH (less than 2.5) and decrease in gastric secretions volume (greater than 0.4ml/kg).

Presidential elections: centrality, context, and implications

Lima Junior Olavo Brasil de

2000-01-01

Full Text Available The author argues that the conjugation of certain democratic, socioeconomic and political factors has led to the "nationalization" of presidential elections in Brazil since 1960. The expansion of the electoral market resulting from urbanization and the growth of the electorate, together with the progressive removal of the obstacles to voting - due to income, gender, age, and education - has democratized the electoral process by diversifying the social structure of the electorate. Since then, the president's election has ceased to depend solely upon rural political forces and now involves multiple combinations of rural and urban political forces. Candidates can no longer count on specific social groups in order to guarantee their election, and need to widen their appeal. Based on the results of the direct presidential elections of 1960, 1989, 1994 and 1998, the author contends that the "nationalization" of the vote is part of the political integration of Brazilian society and that this, together with the social complexity of the electorate, means that the candidate's appeal and political stance need to be more wide-ranging in order to prevent potential conflicts from arising during the election campaign.

The ideal method for managing concomitant gallbladder stones and common bile duct (CBD) stones is debatable. The currently preferred method is two-stage endoscopic stone extraction followed by laparoscopic cholecystectomy (LC). This prospective randomized trial compared the success and cost effectiveness of single- and two-stage management of patients with concomitant gallbladder and CBD stones. Consecutive patients with concomitant gallbladder and CBD stones were randomized to either single-stage laparoscopic CBD exploration and cholecystectomy (group 1) or endoscopic retrograde cholangiopancreatography (ERCP) for endoscopic extraction of CBD stones followed by LC (group 2). Success was defined as complete clearance of CBD and cholecystectomy by the intended method. Cost effectiveness was measured using the incremental cost-effectiveness ratio. Intention-to-treat analysis was performed to compare outcomes. From February 2009 to October 2012, 168 patients were randomized: 84 to the single-stage procedure (group 1) and 84 to the two-stage procedure (group 2). Both groups were matched with regard to demographic and clinical parameters. The success rates of laparoscopic CBD exploration and ERCP for clearance of CBD were similar (91.7 vs. 88.1 %). The overall success rate also was comparable: 88.1 % in group 1 and 79.8 % in group 2 (p = 0.20). Direct choledochotomy was performed in 83 of the 84 patients. The mean operative time was significantly longer in group 1 (135.7 ± 36.6 vs. 72.4 ± 27.6 min; p ≤ 0.001), but the overall hospital stay was significantly shorter (4.6 ± 2.4 vs. 5.3 ± 6.2 days; p = 0.03). Group 2 had a significantly greater number of procedures per patient (p gallbladder and CBD stones had similar success and complication rates, but the single-stage strategy was better in terms of shorter hospital stay, need for fewer procedures, and cost effectiveness.

Its antiemetic effect is demonstrated in chemotherapy-induced acute and delayed onset of nausea and vomiting in breast cancer patients. Aim: To evaluate the antiemetic effect of gabapentin on incidence and severity of postoperative nausea and vomiting in laparoscopic cholecystectomy. Settings and Design: Double-blind, randomized, placebo-controlled study. Materials and Methods: Two hundred and fifty patients of ASA physical status I and II, scheduled for laparoscopic cholecystectomy were randomly assigned into two equal groups to receive 600 mg gabapentin or matching placebo two hours before surgery. Standard anaesthesia technique was used. Fentanyl was used as rescue postoperative analgesic. Ondansetron 4 mg was used intravenously as rescue medication for emesis. The total number of patients who had nausea or vomiting, and its severity and total fentanyl consumption in the first 24 hours were recorded. Statistical Analysis: "Z test" was used to test the significance of severity of post-operative nausea and vomiting between groups. Fentanyl consumed in each group (Mean±SD within 24 hrs was compared using student t test. P value< 0.05 was considered significant. Results: There were no demographic difference between the two groups. Incidence of post-operative nausea and vomiting within 24 hrs after laparoscopic cholecystectomy was significantly lower in gabapentin group (46/125 than in the placebo group (75/125 (37.8% vs 60%; P =0.04. There was a significantly decreased fentanyl consumption in gabapentin group (221.2±92.4 µg as compared to placebo group (505.9±82.0 µg; P =0.01. Conclusion: Gabapentin effectively suppresses nausea and vomiting in laparoscopic cholecystectomy and post-operative rescue analgesic requirement.

Cholescintigraphy was made in 42 patients with postcholecystectomy syndrome and 8 asymptomatic volunteers. In 7 cases organic disorders were diagnosed. Among the remaining 35, in 11 patients sphincter Oddi dysfunction and in 12 duodenogastric reflux were diagnosis. The others had normal results of cholescintigraphy. This study shows that cholescintigraphy is useful in diagnosis of functional disorders of bile in patients after cholecystectomy. (author). 21 refs, 4 figs, 2 tabs

Veres needle in the umbilical fundus, followed by the insertion of a 5-mm trocar. A second 3-mm trocar was placed in the right upper quadrant. A colpotomy was performed, and a 12-mm trocar placed inside the vagina allowed the insertion of a videogastroscope as far as the hilum of the liver. Results: cholecystectomy was performed by using a combination of working tools inserted through the entry port for the minilaparoscopy and the videogastroscope. The gallbladder was removed transvaginally through the videogastroscope. There were no postoperative complications, and the patient was discharged within 24 hours. Conclusions: transvaginal cholecystectomy is possible and safe when performed by a multidisciplinary team working together. Natural orifice transluminal endoscopic surgery (NOTES is an emerging modality that seeks to be less invasive, better tolerated, and more respectful of esthetics than laparoscopic surgery. It will probably open the way for very important medical and technological innovations over the coming years.

Small cell cervical cancer: an unusual finding at cholecystectomy.

LENUS (Irish Health Repository)

Boyle, Emily

2012-02-01

BACKGROUND: Small cell carcinoma of the cervix is a rare cancer, comprising less than 3% of all cervical neoplasms. It uniformly has a poor prognosis, and has a high mortality even with early stage disease. It can metastasise rapidly and metastatic sites include lung, liver, brain, bone, pancreas and lymph nodes. CASE: Here, we report the case of a 60-year-old woman with no symptoms of cervical pathology who developed post-renal failure following a laparoscopic cholecystectomy. The cause was bilateral ureteric obstruction from metastatic small cell cervical cancer and metastases were subsequently found on her gallbladder specimen. CONCLUSION: This is an unusual presentation of small cell cervical cancer and demonstrates the aggressive nature of this disease.

Intra-Hepatic Spillage of Gallstones as a Late Complication of Laparoscopic Cholecystectomy: MR Imaging Findings

International Nuclear Information System (INIS)

Ragozzino, Alfonso; Puglia, Marta; Romano, Federica; Imbriaco, Massimo

2016-01-01

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. 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. 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

A psychodynamic perspective on elections.

Science.gov (United States)

Clemens, Norman A

2010-11-01

In a democracy, elections are the way in which the collective thought processes of the voters arrive at a decision to direct their government. The author explores how the individual voter assesses and resolves many conflicting internal and external forces to arrive at a vote. The midterm elections of 2010 illustrate the parallel between individual resolution of conflicting forces and the process of a campaign leading to the outcome of an election. The psychodynamic concepts of conflict and compromise, affects, aggression, unconscious forces, mechanisms of defense, superego, and the ego's integrative functions are evident in both the individual voter and the collective electoral process. The author expresses concern about the historical vulnerability of democracies and the unbalancing effect of allowing limitless infusion of anonymous corporate money to pour into campaigns.

Long-term Outcomes of Elective Surgery for Diverticular Disease: A Call for Standardization.

Science.gov (United States)

Biondi, Alberto; Santullo, Francesco; Fico, Valeria; Persiani, Roberto

2016-10-01

To date, the appropriate management of diverticular disease is still controversial. The American Society of Colon and Rectal Surgeons declared that the decision between conservative or surgical approach should be taken by a case-by-case evaluation. There is still lack of evidence in literature about long-term outcomes after elective sigmoid resection for diverticular disease. Considering the potentially key role of the surgical technique in long-term outcomes, there is the need for surgeons to define strict rules to standardize the surgical technique. Currently there are 5 areas of debate in elective surgery for diverticular disease: laparoscopic versus open approach, the site of the proximal and distal colonic division, the vascular approach and the mobilization of the splenic flexure. The purpose of this paper is to review existing knowledge about technical aspects, which represent how the surgeon is able to affect the long-term results.

From a relational marketing paradigm, we have tried to define the concept of local proximity-based political communication, the grounds for a research program based on a quasi-experimental plan aimed at verifying a set of assumptions on the effects of local proximity-based political communication on the mobilization of Portuguese voters for the EP elections of 2004 and 2009. The results are clear: the proximity-based political communication generated significant electoral mobilization in those two elections.

We propose a methodology for identifying and analysing 'elective' preterm births (PTBs) using administrative data, and apply this methodology to California data with the objective of providing a framework to further explore the potential rationales for early delivery. Using the California linked birth cohorts for 1999, 2002 and 2005, singleton PTBs were identified using birth certificate gestational age ≥ 24 and PTBs increased 27.7% over the 6-year study period, with nearly all cases confined to the late PTB stratum; elective late PTB rates rose from 10.5% to 13.5% of all late PTBs (P PTBs that is 'elective'. This method can be used to explore and monitor potential strategies for the prevention of elective PTB. © 2012 Blackwell Publishing Ltd.

The retrospection of Romania presidential elections of 2014

2015-03-01

Full Text Available The aim of this paper is to take a radiograph of Romania presidential elections of 2014, starting from a general framework in which these elections were held, continuing with issues and debates that characterized this context and ending with international reactions regarding the new elected-president in the foreign press and from the officials. This radiograph brings a series of questions: was the final result of these elections an accident? Was it an express of confidence for the successful candidate or the result of discontent with the current political system, a vote of hope? In this regard, I consider absolutely necessary to understand how the president was elected, the reasons behind this choice and especially if the hopes of voters will be reflected in the work of Klaus Iohannis during his term.

Lee, Jun Suh; Seo, Ho Seok; Hong, Tae Ho

2015-08-01

The purpose of this study was to analyze the educational quality of laparoscopic cholecystectomy (LC) videos accessible on YouTube, one of the most important sources of internet-based medical information. The keyword 'laparoscopic cholecystectomy' was used to search on YouTube and the first 100 videos were analyzed. Among them, 27 videos were excluded and 73 videos were included in the study. An arbitrary score system for video quality, devised from existing LC guidelines, were used to evaluate the quality of the videos. Video demographics were analyzed by the quality and source of the video. Correlation analysis was performed. When analyzed by video quality, 11 (15.1%) were evaluated as 'good', 40 (54.8%) were 'moderate', and 22 (30.1%) were 'poor', and there were no differences in length, views per day, or number of likes, dislikes, and comments. When analyzed by source, 27 (37.0%) were uploaded by primary centers, 20 (27.4%) by secondary centers, 15 (20.5%) by tertiary centers, 5 (6.8%) by academic institutions, and 6 (8.2%) by commercial institutions. The mean score of the tertiary center group (6.0 ± 2.0) was significantly higher than the secondary center group (3.9 ± 1.4, P = 0.001). The video score had no correlation with views per day or number of likes. Many LC videos are accessible on YouTube with varying quality. Videos uploaded by tertiary centers showed the highest educational value. This discrepancy in video quality was not recognized by viewers. More videos with higher quality need to be uploaded, and an active filtering process is necessary.

A 50-year-old male was examined at another hospital for fever, general fatigue and slight abdominal pain. He was treated with antibiotics and observed. However, his symptoms did not lessen, and laboratory tests revealed liver dysfunction, jaundice and an increased inflammatory response. He was then admitted to our hospital and underwent an abdominal computed tomography scan and magnetic resonance cholangiopancreatography (MRCP), which revealed common bile duct (CBD) stones. He was diagnosed with mild acute cholangitis. As the same time, he was admitted to our hospital and an emergency endoscopic retrograde cholangiopancreatography was performed. Vater papilla opening in the third portion of the duodenum and presence of a peripapillary duodenal diverticulum made it difficult to perform cannulation of the CBD. In addition, MRCP revealed that the CBD was extremely narrow (diameter 5 mm). We therefore performed laparoscopic cholecystectomy and endoscopic sphincterotomy using the rendezvous technique for choledocholithiasis simultaneously rather than laparoscopic CBD exploration. After the operation, the patient was discharged with no complications. Although the rendezvous technique has not been very commonly used because several experts in the technique and a large operating room are required, this technique is a very attractive and effective approach for treating choledocholithiasis, for which endoscopic treatment is difficult.

Post-operative nausea and vomiting (PONV) is a common and distressing complication after laparoscopic cholecystectomy (LC). The aim of this study was to evaluate the effect of intravenous (IV) dextrose administration for the prophylaxis of PONV after LC. In a double-blind, randomised controlled trial, a total of 150 female patients who were scheduled for elective LC were randomly assigned into two groups (A and B). Thirty minutes before induction of anaesthesia, patients received an infusion of 500 cc lactated Ringer's solution (Group A) and 5% dextrose in lactated Ringer's solution (Group B) and over a period of 30 min. All patients rated their nausea and vomiting intensity using the verbal rating scale immediately at post-anaesthesia care unit (PACU) arrival; 30, 60, 90 and 120 min after arriving at the PACU and 6, 12 and 24 h after surgery. There was a statistically significant time trend and group effect along with significant differences in time/group interaction effect in both groups for nausea and vomiting scores ( P Dextrose administration reduced the odds of vomiting events compared to placebo (estimate: -0.87, odds ratio = 0.42, 95% confidence interval: 0.28-0.64). Administration of IV dextrose before anaesthesia induction may be recommended as an effective, and safe method for the prophylaxis of PONV after LC.

Electives: isn't it time for a change?

Science.gov (United States)

Dowell, Jon; Merrylees, Neil

2009-02-01

Medical student electives are memorable learning experiences, of which approximately 40% are spent in developing countries. Students often have laudable motivation but are rarely helped to learn most effectively or contribute meaningfully whilst away. Each year an estimated 350 years of elective time is spent in developing countries (by students from the UK alone), which represents substantial opportunity. We conducted a literature search prior to developing an alternative approach towards electives based upon educational and ethical principles. Despite their anecdotal value there has been little empirical research conducted into electives. From our review we identified four key learning domains (Clinical Knowledge and Skills, Attitudes, Global Perspectives, Personal and Professional Development) and two broader issues (Institutional Benefits and Moral/Ethical Considerations). Potentially beneficial and more structured alternatives are emerging and improvements appear possible through institutional collaborations and greater planning in order to maximise the educational experience, opportunities to contribute and minimise the risks involved in electives. Electives are a highlight of clinical training but probably often represent missed opportunities. There are both educational and moral reasons for seeking more considered approaches to reduce the 'medical tourism' that can result from the current largely ad hoc arrangements.
