Abstract
BACKGROUND Laparoscopic surgery is the preferred option for many procedures. To properly perform laparoscopic surgery, it is essential that sudden movements and abdominal contractions in patients are prevented, as it limits the surgeon's view. There has been a growing interest in the potential beneficial effect of deep neuromuscular blockade (NMB) in laparoscopic surgery. Deep NMB improves the surgical field by preventing abdominal contractions, and it is thought to decrease postoperative pain. However, it is uncertain if deep NMB improves intraoperative safety and thereby improves clinical outcomes. OBJECTIVES To evaluate the benefits and harms of deep neuromuscular blockade versus no, shallow, or moderate neuromuscular blockade during laparoscopic intra- or transperitoneal procedures in adults. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 31 July 2023. SELECTION CRITERIA We included randomised clinical trials (irrespective of language, blinding, or publication status) in adults undergoing laparoscopic intra- or transperitoneal procedures comparing deep NMB to moderate, shallow, or no NMB. We excluded trials that did not report any of the primary or secondary outcomes of our review. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were 1. all-cause mortality, 2. health-related quality of life, and 3. proportion of participants with serious adverse events. Our secondary outcomes were 4. proportion of participants with non-serious adverse events, 5. readmissions within three months, 6. short-term pain scores, 7. measurements of postoperative recovery, and 8. operating time. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS We included 42 randomised clinical trials with 3898 participants. Most trials included participants undergoing intraperitoneal oncological resection surgery. We present the Peto fixed-effect model for most dichotomous outcomes as only sparse events were reported. Comparison 1: deep versus moderate NMB Thirty-eight trials compared deep versus moderate NMB. Deep NMB may have no effect on mortality, but the evidence is very uncertain (Peto odds ratio (OR) 7.22, 95% confidence interval (CI) 0.45 to 115.43; 12 trials, 1390 participants; very low-certainty evidence). Deep NMB likely results in little to no difference in health-related quality of life up to four days postoperative (mean difference (MD) 4.53 favouring deep NMB on the Quality of Recovery-40 score, 95% CI 0.96 to 8.09; 5 trials, 440 participants; moderate-certainty evidence; mean difference lower than the mean clinically important difference of 10 points). The evidence is very uncertain about the effect of deep NMB on intraoperatively serious adverse events (deep NMB 38/1150 versus moderate NMB 38/1076; Peto OR 0.95, 95% CI 0.59 to 1.52; 21 trials, 2231 participants; very low-certainty evidence), short-term serious adverse events (up to 60 days) (deep NMB 37/912 versus moderate NMB 42/852; Peto OR 0.90, 95% CI 0.56 to 1.42; 16 trials, 1764 participants; very low-certainty evidence), and short-term non-serious adverse events (Peto OR 0.94, 95% CI 0.65 to 1.35; 11 trials, 1232 participants; very low-certainty evidence). Deep NMB likely does not alter the duration of surgery (MD -0.51 minutes, 95% CI -3.35 to 2.32; 34 trials, 3143 participants; moderate-certainty evidence). The evidence is uncertain if deep NMB alters the length of hospital stay (MD -0.22 days, 95% CI -0.49 to 0.06; 19 trials, 2084 participants; low-certainty evidence) or pain scores one hour after surgery (MD -0.31 points on the numeric rating scale, 95% CI -0.59 to -0.03; 22 trials, 1823 participants; very low-certainty evidence; mean clinically important difference 1 point) and 24 hours after surgery (MD -0.60 points on the numeric rating scale, 95% CI -1.05 to -0.15; 16 trials, 1404 participants; very low-certainty evidence; mean clinically important difference 1 point). Comparison 2: deep versus shallow NMB Three trials compared deep versus shallow NMB. The trials did not report on mortality and health-related quality of life. The evidence is very uncertain about the effect of deep NMB compared to shallow NMB on the proportion of serious adverse events (RR 1.66, 95% CI 0.50 to 5.57; 2 trials, 158 participants; very low-certainty evidence). Comparison 3: deep versus no NMB One trial compared deep versus no NMB. There was no mortality in this trial, and health-related quality of life was not reported. The proportion of serious adverse events was 0/25 in the deep NMB group and 1/25 in the no NMB group. AUTHORS' CONCLUSIONS There was insufficient evidence to draw conclusions about the effects of deep NMB compared to moderate NMB on all-cause mortality and serious adverse events. Deep NMB likely results in little to no difference in health-related quality of life and duration of surgery compared to moderate NMB, and it may have no effect on the length of hospital stay. Due to the very low-certainty evidence, we do not know what the effect is of deep NMB on non-serious adverse events, pain scores, or readmission rates. Randomised clinical trials with adequate reporting of all adverse events would reduce the current uncertainties. Due to the low number of identified trials and the very low certainty of evidence, we do not know what the effect of deep NMB on serious adverse events is compared to shallow NMB and no NMB. We found no trials evaluating mortality and health-related quality of life.

Evaluation of preoperative duloxetine use for postoperative analgesia following laparoscopic cholecystectomy: A randomized controlled trial. Front Pharmacol 2022; 13:944392. [PMID: 36249765 PMCID: PMC9557153 DOI: 10.3389/fphar.2022.944392] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 08/24/2022] [Indexed: 11/28/2022] Open
Abstract
Background: The pain pattern after laparoscopic cholecystectomy (LC) is complex and distinct from postoperative pain after other laparoscopic procedures, suggesting that procedure-specific optimal analgesic management plans should be proposed. Duloxetine, a non-opioid neuromodulator, has been widely used to manage pain with dual central and peripheral analgesic properties. Aims: To assess the effect of preoperative administration of duloxetine compared to placebo on postoperative pain control in patients undergoing LC. Patients and Methods: This study was a randomized, parallel-group, placebo-controlled, double-blinded study performed on patients undergoing LC. Patients were randomly divided into two groups of 30 each on the day of surgery in the preoperative holding area, using a computer-generated random number to receive 60 mg duloxetine as a single oral dose 2 h before the procedure or placebo. The primary outcome was the difference in the mean of visual analogue scale (VAS) scores between the two studied groups, as measured by the area under the curve (AUC) of the VAS scores. Results: The derived AUC of VAS scores in the duloxetine group (757.89 ± 326.01 mm × h) was significantly lower than that calculated for the control group (1005.1 ± 432.5 mm × h). The mean postoperative VAS scores recorded at 4 and 24 h were statistically different between the study groups (p = 0.041 and 0.003, respectively). As observed in the survival curve analysis, there was no significant difference (p = 0.665) for the time until the patient’s first request for rescue medications in the two groups. The frequency of postoperative nausea and vomiting (PONV) was lower in patients of the duloxetine group than that recorded in those allocated to the control group at 8 and 24-h time intervals (p = 0.734 and 0.572, respectively). Conclusion: Preoperative use of duloxetine reduces postoperative pain significantly compared with placebo. In addition, its use is associated with a reduction in PONV. These preliminary findings suggest that duloxetine could play a role in the acute preoperative period for patients undergoing LC.

Abstract
OBJECTIVE To test the hypothesis that ICG fluorescence cholangiography (ICG-FC) helps to identify critical structures during laparoscopic cholecystectomy (LC) and hence reduce biliary injuries and conversions. In LC, biliary injury and conversion often happen if the biliary anatomy is misidentified. METHODS This was a single-center randomized controlled trial from 2017 to 2019. Patients with acute cholecystitis requiring LC were assessed for eligibility for the trial. Patients in the trial were randomized to undergo either conventional LC (conventional arm) or LC with ICG-FC (ICG arm). Conversion rate and biliary injury incidence were outcome measures. RESULTS Totally 92 patients participated (46 patients in each arm). The median age was 61 years in both arms (p = 0.472). The conventional arm had 22 men and 24 women; the ICG arm had 24 men and 22 women (p = 0.677). The two arms were comparable in all perioperative parameters. The time from ICG injection to surgery was 67 (16-1150) min. Both arms had an 8.7% conversion rate (p = 1.000). The median operative time was 140.5 min in the conventional arm and 149.5 min in the ICG arm (p = 0.086). The complication rate was 15.2% in the former and 10.9% in the latter (p = 0.536), and both had a 2.2% bile leakage rate. The median hospital stay was 3.5d in the former and 4.0d in the latter (p = 0.380). CONCLUSION ICG-FC did not make any difference in conversion or complication rate. Its routine use in LC is questionable. However, it may be helpful in difficult cholecystectomies and may be used as an adjunct. TRIAL REGISTRATION The trial was registered with the Institutional Review Board of University of Hong Kong/Hospital Authority Hong Kong West Cluster ( http://www.med.hku.hk/en/research/ethics-and-integrity/human-ethics ). Registration number: UW17-492.

Abstract
OBJECTIVE To study the Cochrane evidence base of systematic reviews and meta-analyses regarding development of national guidelines for surgical treatment of gallstone disease and its complications. MATERIAL AND METHODS We analyzed the original database involving 35 systematic reviews and meta-analyses of Cochrane Library devoted to gallstone disease and its complications. Methodology of electronic and manual searching of trials was used for identification and screening of information for the period until October 2021. RESULTS There were 430 randomized controlled trials from different countries estimated in 35 systematic reviews of Cochrane Library. At the same time, Russian-language researches are not included in the world's evidence database of biliary tract surgery. Expert groups couldn't perform meta-analysis and limited to systematic-review in 6 (17%) publications because of insufficient statistical power or primary researches. Need for further research of this issue was determined after assessment of 26 (74%) meta-analyses. CONCLUSION We have to convey foreign experience as subbase of national clinical guidelines taking into account deficiency of scientific trials with high level of evidence in our country. Need for further evidence trials, considering the peculiarities of surgical care in the Russian Federation, is determined by unsolved issues of treatment of gallstone disease and its complications.

Abstract
Background Laparoscopic cholecystectomy (LC) is a gold standard treatment of symptomatic gallstone disease. Meanwhile, it is also a challenging procedure demanding excellent expertise for the best outcomes. Many times, difficult laparoscopic cholecystectomy is a nerve-wracking situation for surgeons. It endangers patients by causing potential injury to vital structures. Thus, we aimed to identify predictors for difficult LC. Methods A retrospective cross-sectional review of surgical records was done. Patients who underwent laparoscopic cholecystectomy on an elective basis from July 2017 to June 2021 were included in the study. We divided our patients into two groups based on operative findings of difficult LC; difficult LC group and non-difficult LC group. We compared patient's demographics, predictors, and perioperative details and analyzed the data. Results A total of 338 patients (82 males) with a median age of 47 years were studied. Total difficult LC was found in 52 patients (15.4%). The overall conversion rate was 8.9%. Logistic multivariable regression analysis revealed that; male gender (odds ratio (OR); 0.171, confidence interval (CI),(0.043-0.675), P; 0.012), past history of acute cholecystitis (OR; 0.038, CI; (0.005-0.309), P; 0.002), gall bladder wall thickness (≥4-5 mm) (OR; 0.074, CI; (0.008-0.666), P; 0.020), fibrotic gallbladder (OR; 166.6, CI; (7.946-3492), P; 0.001), and adhesion at Calot's triangle (OR; 0.021, CI (0.001-0.311), P; 0.005) were independent predictors of difficult LC. Conclusions Gender (male), past history of acute cholecystitis, gallbladder wall thickness (≥4-5 mm), fibrotic gallbladder, and adhesion at Calot's triangle are significant predictors for difficult LC. Moreover, an awareness about reliable predictors for difficult LC would be helpful for an appropriate treatment plan and application of the resources to anticipate difficult LC.

Abstract
OBJECTIVE To analyze the impact of laparoscopic cholecystectomy on in-hospital and postoperative mortality in patients with acute cholecystitis. MATERIAL AND METHODS Comparative analysis was based on primary statistical data presented in public available analytical collections «Surgical care in the Russian Federation» (Revishvili A.Sh. et al. 2019, 2020). Depending on introduction of laparoscopic surgery, all regions were divided into 4 groups. Between-group analysis of differences was carried out using χ2 test. Statistical processing was performed using SPSS Statistics software package for Windows. RESULTS According to 2-year follow-up data (2018, 2019), in-hospital mortality was 0.97 and 0.95% and postoperative mortality was 1.36 and 1.47%, respectively, in the regions with percentage of laparoscopic surgery for patients with acute cholecystitis was less than 25%. In the second group (percentage of laparoscopic surgery 25.01 - 50%), in-hospital mortality was 0.95 and 1.14%, postoperative mortality - 1.38 and 1.71%. In the third group (percentage of laparoscopic surgery 50.01 - 75%), in-hospital mortality was 0.92 and 0.99%, postoperative mortality - 1.27 and 1.38%. In the fourth group, percentage of laparoscopic surgery exceeded 75%. In-hospital mortality was 0.61 and 0.74%, postoperative mortality - 0.76 and 0.98%, respectively. Analysis of multi-field contingency tables revealed non-random between-group differences of in-hospital (p<0.001) and postoperative (p<0.001) mortality, as well as significant decrease of mortality following laparoscopic surgery. We also analyzed mortality after laparoscopic surgery considering technology maturity curve. CONCLUSION In-hospital and postoperative mortality in acute cholecystitis depend on availability of laparoscopic technologies.

Abstract
BACKGROUND The lack of studies showing benefit from surgery in patients with symptoms of gallstone disease has led to a divergence in local practices and standards of care. This study aimed to explore regional differences in management and complications in Sweden. Furthermore, to study whether population density had an impact on management. METHODS Data were collected from the Swedish National Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks). Cholecystectomies undertaken for gallstone disease between January 2006 and December 2017 were included. Age, sex, American Society of Anesthesiologists (ASA) classification, intra- and post-operative complications, and the proportion of patients with acute cholecystitis who underwent surgery within 2 days of hospital admission were analyzed. The 21 different geographical regions in Sweden were compared, and each variable was analyzed according to population density. RESULTS A total of 139,444 cholecystectomies cases were included in this study. There were large differences between regions regarding indications for surgery and intra- and post-operative complications. In the analyses, there were greater divergences than would be expected by chance for most of the variables analyzed. Age of the cholecystectomized patients correlated with population density of the regions (R2 = 0.310; p = 0.0088). CONCLUSIONS There are major differences between the different regions in Sweden in terms of the treatment of gallstone disease and outcome, but these did not correlate to population density, suggesting that local routines are more likely to have an impact on treatment strategies rather than demographic factors. These differences need further investigation to reveal the underlying causes.

Abstract
Residual intra-peritoneal gas may be associated with post-laparoscopic shoulder pain (PLSP), which is a frequently and disturbance compliant after surgery. Herein, we aimed to examine whether expiring residual gas via a surgical drain reduces the frequency and intensity of PLSP in the first day after laparoscopic cholecystectomy. 448 participants were enrolled in this prospective cohort study. The incidence and severity of PLSP after surgery were recorded. Of these, the cumulative incidence of PLSP in the drain group was lower particularly at the 12th postoperative hour (18.3% vs. 27.6%; P = 0.022), 24th postoperative hour (28.8% vs. 38.1%; P = 0.039), and throughout the first postoperative day (P = 0.035). The drain group had less severe PLSP (crude Odds ratio, 0.66; P = .036). After adjustment using inverse probability of treatment weighting, the drain group also had a significant lower PLSP incidence (adjusted hazard ratio = 0.61, P < 0.001), and less severe PLSP (adjusted odds ratio = 0.56, P < 0.001). In conclusion, the maneuver about passive force to expel residual gas, surgical drain use, contributes to reduce the incidence and severity of PLSP, suggesting that to minimize residual gas at the end of surgery is useful to attenuate PLSP.

[PMID: 33991327 DOI: 10.1007/s13304-021-01081-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 05/03/2021] [Indexed: 12/07/2022]
Abstract
The present meta-analysis was performed to compare the efficacy and safety of percutaneous cholecystostomy (PC) versus emergency cholecystectomy (EC) for the treatment of acute calculous cholecystitis (ACC) in high-risk surgical patients. Literature searches for eligible studies were performed using MEDLINE, EMBASE and the Cochrane Library. Quality assessment was conducted in each study. Meta-analyses were performed to demonstrate the pooled effects of relative risk (RR) with 95% confidence intervals (CI). A total of 8960 patients from 6 studies were finally included. PC resulted in increased risks of mortality (RR = 2.87; CI = 1.33-6.18; p = 0.007) and readmission rate (RR = 4.70; CI = 3.30-6.70; p < 0.00001) as compared with EC. No significant difference was detected between PC and EC in terms of morbidity, severe complication rate or hospitalization length. Moreover, PC was associated with significantly higher risks of mortality (RR = 7.47; CI = 1.88-29.72; p = 0.004), morbidity (RR = 3.71; 95% CI = 1.78-7.75; p = 0.0005), readmission rate (RR = 7.91; CI = 3.80-16.49; p < 0.00001), and hospitalization length (WMD = 6.92; CI = 5.89-7.95; p < 0.00001) when directly compared with laparoscopic cholecystectomy (LC). Therefore, EC is superior to PC for the treatment of ACC in high-risk surgical patients, and LC is the preferred surgical strategy.

Abstract
Acute cholecystitis (AC) is the most common biliary stone disease complication. While there is consensus regarding cholecystectomy for AC, gallbladder drainage is indicated in elderly or high-risk surgical patients. We systematically reviewed available evidence in the field of EUS-guided gallbladder drainage (EUS-GBD) for AC in high-risk surgical patients. The studies were classified according to their level of evidence (LE) according to the Oxford Centre for Evidence Based Medicine classification. Literature search retrieved 175 manuscripts; most of them were expert opinions (LE V, no. 53) or caseseries (LE IV, no. 29). There was no meta-analysis of RCT (LE Ia), while two randomized controlled trials (LE Ib) demonstrated that EUS-GBD was superior to percutaneous trans-hepatic-GBD (PT-GBD) regarding longterm outcomes (adverse events, recurrent cholecystitis, and reintervention). Several meta-analyses of cohort studies (LE IIa, no. 11) were designed to compare the three available drainage strategies (endoscopic, echoendoscopic and percutaneous) and to assess the pooled risk of adverse events. Comparison between surgery and EUS-GBD was done in a single retrospective study with a propensity score analysis (LE III). The outcomes of conversion from PT-GBD to EUS-GBD were covered by few retrospective studies (LE III). Several manuscripts (no. 69) were published on EUS-GBD as a rescue strategy in case of malignant biliary obstruction. The levels of evidence of EUS-GBD in the literature have evolved from initial descriptive studies to recent randomized controlled trials and meta-analysis of cohort studies. While several articles addressed the comparison among different techniques for GBD, in our opinion some topics and questions have not been adequately investigated. are still debated.

Abstract
Uncontrolled movements of laparoscopic instruments can lead to inadvertent injury of adjacent structures. The risk becomes evident when the dissecting instrument is located outside the field of view of the laparoscopic camera. Technical solutions to ensure patient safety are appreciated. The present work evaluated the feasibility of an automated binary classification of laparoscopic image data using Convolutional Neural Networks (CNN) to determine whether the dissecting instrument is located within the laparoscopic image section. A unique record of images was generated from six laparoscopic cholecystectomies in a surgical training environment to configure and train the CNN. By using a temporary version of the neural network, the annotation of the training image files could be automated and accelerated. A combination of oversampling and selective data augmentation was used to enlarge the fully labeled image data set and prevent loss of accuracy due to imbalanced class volumes. Subsequently the same approach was applied to the comprehensive, fully annotated Cholec80 database. The described process led to the generation of extensive and balanced training image data sets. The performance of the CNN-based binary classifiers was evaluated on separate test records from both databases. On our recorded data, an accuracy of 0.88 with regard to the safety-relevant classification was achieved. The subsequent evaluation on the Cholec80 data set yielded an accuracy of 0.84. The presented results demonstrate the feasibility of a binary classification of laparoscopic image data for the detection of adverse events in a surgical training environment using a specifically configured CNN architecture.

Abstract
Background Recent evidences suggest that gallbladder drainage is the treatment of choice in elderly or high-risk surgical patients with acute cholecystitis (AC). Despite better outcomes compared to other approaches, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is burdened by high mortality. The aim of the study was to evaluate predictive factors for mortality in high-risk surgical patients who underwent EUS-GBD for AC. Methods A retrospective analysis of a prospectively maintained database was performed. Electrocautery-enhanced lumen-apposing metal stents were used; all recorded variables were evaluated as potential predictive factors for mortality. Results Thirty-four patients underwent EUS for suspected AC and 25 (44% male, age 78) were finally included. Technical, clinical success rate and adverse events rate were 92%, 88%, and 16%, respectively. 30-day and 1-year mortality were 12% and 32%. On univariate analysis, age-adjusted Charlson Comorbidity Index (CCI) (OR 20.8[4–68.2]), acute kidney injury (AKI) (OR 21.4[2.6–52.1]) and clinical success (OR 8.9[1.2–11.6]) were related to 30-day mortality. On multivariate analysis, CCI and AKI were independently related to long-term mortality. Kaplan–Meier curves showed an increased long-term mortality in patients with CCI > 6 (hazard ratio 7.6[1.7–34.6]) and AKI (hazard ratio 11.3[1.4–91.5]). Conclusions Severe comorbidities and AKI were independent predictive factors confirming of long-term mortality after EUS-GBD. Outcomes of EUS-GBD appear more influenced by patients’ conditions rather than by procedure success.

Difficult laparoscopic cholecystectomy and preoperative predictive factors. Sci Rep 2021; 11:2559.

Abstract
Laparoscopic cholecystectomy (LC) is the standard technique for treatment of gallbladder disease. In case of acute cholecystitis we can identify preoperative factors associated with an increased risk of conversion and intraoperative complications. The aim of our study was to detect preoperative laboratory and radiological findings predictive of difficult LC with potential advantages for both the surgeons and patients in terms of options for management. We designed a retrospective case-control study to compare preoperative predictive factors of difficult LC in patients treated in emergency setting between January 2015 and December 2019. We included in the difficult LC group the surgeries with operative time > 2 h, need for conversion to open, significant bleeding and/or use of synthetic hemostats, vascular and/or biliary injuries and additional operative procedures. We collected 86 patients with inclusion criteria and difficult LC. In the control group, we selected 86 patients with inclusion criteria, but with no operative signs of difficult LC. The analysis of the collected data showed that there was a statistically significant association between WBC count and fibrinogen level and difficult LC. No association were seen with ALP, ALT and bilirubin values. Regarding radiological findings significant differences were noted among the two groups for irregular or absent wall, pericholecystic fluid, fat hyperdensity, thickening of wall > 4 mm and hydrops. The preoperative identification of difficult laparoscopic cholecystectomy provides an important advantage not only for the surgeon who has to perform the surgery, but also for the organization of the operating block and technical resources. In patients with clinical and laboratory parameters of acute cholecystitis, therefore, it would be advisable to carry out a preoperative abdominal CT scan with evaluation of features that can be easily assessed also by the surgeon.

Abstract
The incidence of laparoscopy-related shoulder pain reaches 90% in women. We evaluated the effect of lidocaine patch 5% on the shoulder pain after laparoscopic cholecystectomy (LC) in female patients. Total 63 female patients were randomly allocated to patch group (n = 31) and control group (n = 32). Patch group received lidocaine patch 5% and dressing retention tape on both shoulder, and control group received only dressing retention tape. Abdominal and shoulder pains were evaluated with rating on numeric rating scale (0 = no pain and 10 = the worst pain) at baseline and at 30 min, 6 h, 24 h, and 48 h after surgery. There were no significant differences in patient characteristics and operation details. The overall incidence of shoulder pain was significantly lower in patch group than in control group (42% vs. 78%, P = 0.005). The severity of shoulder pain also was significantly reduced in patch group compared to control group at 24 h and 48 h after surgery (P = 0.01 and P = 0.015, respectively). Complications related to lidocaine patch were not found except nausea. Lidocaine patch 5% reduced the incidence and severity of postoperative shoulder pain in female patients undergoing LC without complications.

Abstract
COVID-19 has required changes in the practice of surgery to reduce the risk of transmission of the virus. Proposed mitigation strategies include avoidance of aerosol-generating procedures such as laparoscopy. We report two cases where minilaparotomy cholecystectomy was employed to treat benign biliary disease during the pandemic. A review of the literature supports the use of this surgical technique during the COVID-19 pandemic until laparoscopy can be proven to be safe.

Abstract
Acute calculous cholecystitis (ACC) is a very common complication of gallstone-related disease. Its currently recommended management changes according to severity of disease and fitness for surgery. The aim of this observational study is to assess the short- and long-term outcomes in all-comers admitted with diagnosis of ACC, treated according to 2013 Tokyo Guidelines (TG13). A retrospective analysis was conducted on a prospectively maintained database of 125 patients with diagnosis of ACC consecutively admitted between January 2017 and September 2019, subdivided in three groups according to TG13: percutaneous cholecystostomy (PC group), cholecystectomy (CH group), and conservative medical treatment (MT group). The primary end point was a composite of morbidity and/or mortality rates; the secondary end points were ACC recurrence, readmission, need for cholecystectomy rates and overall length of hospital stay (LOS). After a median follow-up of 639 days, overall morbidity rate was 20.8% and mortality rate was 6.4%. Death was directly related to AC during the index admission in two out of eight cases. There were no significant differences in primary end point according to the treatment group. Concerning secondary end points, ACC recurrence rate was not significantly different after PC (10.0%) or MT (9.1%); the readmission rates were significantly higher (p < 0.0001) in the MT group (48.5%) and in the PC group (25.0%) than in the CH group (5.8%); need for cholecystectomy rates was significantly higher (p < 0.0001) in the MT group (42.4%) than in the PC group (20.0%); median overall LOS was significantly higher in the PC (16 days) than in the MT (9 days) and than in the CH group (5 days). PC is an effective and safe rescue procedure in high-risk patients with ACC, representing a definitive treatment in 80% of cases of this specific subgroup.

Abstract
Background When conducting an Overviews of Reviews on health-related topics, it is unclear which combination of bibliographic databases authors should use for searching for SRs. Our goal was to determine which databases included the most systematic reviews and identify an optimal database combination for searching systematic reviews. Methods A set of 86 Overviews of Reviews with 1219 included systematic reviews was extracted from a previous study. Inclusion of the systematic reviews was assessed in MEDLINE, CINAHL, Embase, Epistemonikos, PsycINFO, and TRIP. The mean inclusion rate (% of included systematic reviews) and corresponding 95% confidence interval were calculated for each database individually, as well as for combinations of MEDLINE with each other database and reference checking. Results Inclusion of systematic reviews was higher in MEDLINE than in any other single database (mean inclusion rate 89.7%; 95% confidence interval [89.0–90.3%]). Combined with reference checking, this value increased to 93.7% [93.2–94.2%]. The best combination of two databases plus reference checking consisted of MEDLINE and Epistemonikos (99.2% [99.0–99.3%]). Stratification by Health Technology Assessment reports (97.7% [96.5–98.9%]) vs. Cochrane Overviews (100.0%) vs. non-Cochrane Overviews (99.3% [99.1–99.4%]) showed that inclusion was only slightly lower for Health Technology Assessment reports. However, MEDLINE, Epistemonikos, and reference checking remained the best combination. Among the 10/1219 systematic reviews not identified by this combination, five were published as websites rather than journals, two were included in CINAHL and Embase, and one was included in the database ERIC. Conclusions MEDLINE and Epistemonikos, complemented by reference checking of included studies, is the best database combination to identify systematic reviews on health-related topics.

Abstract
Backgrounds/Aims Laparoscopic cholecystectomy (LC) has become widely used and preferred standard treatment for gallbladder (GB) disease in many countries. In this study, we aimed to compare the overall clinical outcomes of 3-dimensional (3D) LC system with those of the 2D LC method. Methods We retrospectively analyzed patients who underwent LC for acute cholecystitis between January 2010 and March 2019 at the National Medical Center in Korea. We entered them into 3D LC (group A) and 2D LC (group B) groups. We used Olympus CLV-190 laparoscopic device with dual lenses, capable of displaying both 3D and 2D images. Postoperative variables considered for evaluating between-group differences in clinical outcomes included diet resumption period after surgery, postoperative hospital length-of-stay, outpatient department follow-up period, surgical time, and postoperative surgery-related complications (blood loss and open conversion). Results We analyzed 278 acute cholecystitis patients (Group A, n=116; Group B, n=162). Compared to group B, group A had a significantly reduced surgical time and postoperative hospital stay. Although underlying diseases and abdominal surgical history were more prevalent in the 3D LC group, no significant between-group differences in blood loss and open conversion rate were observed. Conclusions The 3D imaging system offered many advantages over 2D LC, including reduced surgical time and shorter postoperative hospital stay; therefore, it has significance in reducing hospital costs.

Abstract
BACKGROUND Three-dimensional (3D) laparoscopy improves the surgical skills of novice surgeons and positively affects the learning curve in experimental settings. This study aimed to investigate the effect of a 3D passive polarizing display (3DPPD) and a novel 3D head-mounted display (3DHMD; HMS-3000MT) on the performance of the first laparoscopic inguinal hernia repair by novices and compare both systems with standard high-definition 2D (HD2D) laparoscopy. METHODS Patients with symptomatic inguinal hernia underwent transabdominal preperitoneal (TAPP) approach hernia repair using 3DHMD, 3DPPD, or a conventional HD2D laparoscopic system. All surgeries were performed for the first time by three laparoscopically novice surgeons. Operative performance was compared in terms of the time taken for mesh placement and peritoneal suturing under standardized conditions. Additionally, visual perception parameters and adverse effects were assessed. RESULTS The use of both 3D techniques shortened the time required for mesh placement and peritoneal suturing compared with the conventional HD2D approach. Generally, 3D laparoscopy was superior to HD2D laparoscopy in terms of visual perception parameters such as depth perception, sharpness, ghosting, and contrast. However, compared with the use of HD2D laparoscopy, the use of 3DHMD significantly impaired a surgeon's comfort, with the greatest impairment caused by ear discomfort, headaches, and facial and physical discomforts. CONCLUSIONS The 3DHMD and 3DPPD systems showed clear improvement in first hernia repair laparoscopy by novice surgeons in terms of surgical performance, as well as visual perception; however, the 3DHMD system was not superior to the 3DPPD system. The reduction in training time for new surgeons is obviously advantageous. In this respect, the 3D equipment may be a worthwhile investment.

Abstract
Neuromuscular blockade (TOF count = 0) can improve tracheal intubation and microlaryngeal surgery. It is also frequently used in many surgical fields including both nonlaparoscopic and laparoscopic surgery to improve surgical conditions and to prevent sudden muscle contractions. Currently there is a controversy regarding the need and the clinical benefits of deep neuromuscular blockade for different surgical procedures. Deep neuromuscular relaxation improves laparoscopic surgical space conditions only marginally when using low intra-abdominal pressure. There is no outcome-relevant advantage of low compared to higher intra-abdominal pressures, but worsen the surgical conditions. Postoperative, residual curarisation can be avoided by algorithm-based pharmacological reversing and quantitative neuromuscular monitoring.

Abstract
AIM To evaluate the effectiveness and safety of combined ursodeoxycholic acid and percutaneous transhepatic balloon dilation for management of gallstones after expulsion of common bile duct (CBD) stones.
METHODS From April 2014 to May 2016, 15 consecutive patients (6 men and 9 women) aged 45-86 (mean, 69.07 ± 9.91) years suffering from CBD stones associated with gallstones were evaluated. Good gallbladder contraction function was confirmed by type B ultrasonography. Dilation of the CBD and cystic duct was detected. Percutaneous transhepatic balloon dilation of the papilla was performed, ursodeoxycholic acid was administered, and all patients had a high-fat diet. All subjects underwent repeated cholangiography, and percutaneous transhepatic removal was carried out in patients with secondary CBD stones originating from the gallbladder.
RESULTS All patients underwent percutaneous transhepatic balloon dilation with a primary success rate of 100%. The combined therapy was successful in 86.7% of patients with concomitant CBD stones and gallstones. No remaining stones were detected in the gallbladder. Transient adverse events include abdominal pain (n = 1), abdominal distension (n = 1), and fever (n = 1). Complications were treated successfully via nonsurgical management without long-term complications. No procedure-related mortality occurred.
CONCLUSION For patients with concomitant CBD stones and gallstones, after percutaneous transhepatic removal of primary CBD stones, oral ursodeoxycholic acid and a high-fat diet followed by percutaneous transhepatic removal of secondary CBD stones appear to be a feasible and effective option for management of gallstones.

Abstract
OBJECTIVE To assess whether laparoscopic cholecystectomy is superior to percutaneous catheter drainage in high risk patients with acute calculous cholecystitis. DESIGN Multicentre, randomised controlled, superiority trial. SETTING 11 hospitals in the Netherlands, February 2011 to January 2016. PARTICIPANTS 142 high risk patients with acute calculous cholecystitis were randomly allocated to laparoscopic cholecystectomy (n=66) or to percutaneous catheter drainage (n=68). High risk was defined as an acute physiological assessment and chronic health evaluation II (APACHE II) score of 7 or more. MAIN OUTCOME MEASURES The primary endpoints were death within one year and the occurrence of major complications, defined as infectious and cardiopulmonary complications within one month, need for reintervention (surgical, radiological, or endoscopic that had to be related to acute cholecystitis) within one year, or recurrent biliary disease within one year. RESULTS The trial was concluded early after a planned interim analysis. The rate of death did not differ between the laparoscopic cholecystectomy and percutaneous catheter drainage group (3% v 9%, P=0.27), but major complications occurred in eight of 66 patients (12%) assigned to cholecystectomy and in 44 of 68 patients (65%) assigned to percutaneous drainage (risk ratio 0.19, 95% confidence interval 0.10 to 0.37; P<0.001). In the drainage group 45 patients (66%) required a reintervention compared with eight patients (12%) in the cholecystectomy group (P<0.001). Recurrent biliary disease occurred more often in the percutaneous drainage group (53% v 5%, P<0.001), and the median length of hospital stay was longer (9 days v 5 days, P<0.001). CONCLUSION Laparoscopic cholecystectomy compared with percutaneous catheter drainage reduced the rate of major complications in high risk patients with acute cholecystitis.

Abstract
BACKGROUND 3D laparoscopy has proven to be superior to the 2D approach in experimental settings. The aim of the present study was to investigate the influence of 3D laparoscopy using a novel head-mounted display on the performance of defined steps within a laparoscopic inguinal hernia repair. This effect was investigated both in laparoscopically advanced surgeons and in beginners. METHODS Patients suffering from symptomatic inguinal hernia were randomly assigned to laparoscopic hernia repair using either a head-mounted 3D display or a conventional 2D laparoscopic approach. Operative performance of both groups was compared in terms of the time taken for mesh placement and for peritoneal suturing. Additionally, quality of imaging and physical discomfort were assessed. RESULTS The use of a head-mounted 3D display was able to shorten the time required for placement of the mesh as well as that for peritoneal suturing, both for experienced and novice surgeons when compared to the conventional 2D approach. 3D laparoscopy was significantly superior to 2D laparoscopy in terms of depth perception, image sharpness and image contrast. Additionally, increased impairment caused by ghosting effects could not be detected in 3D laparoscopy. Evaluation of image quality was independent of experience in laparoscopic surgery. However, use of a head-mounted 3D display resulted in a significant impairment of surgeon's comfort when compared to 2D laparoscopy. Thereby, the greatest impairment was caused by ear discomfort. CONCLUSIONS This is the first study examining the effect of a head-mounted 3D system on the performance of laparoscopy in a randomized controlled trial (RCT) showing a clear advantage of this system in surgical performance as well as in depth perception and image quality.

Abstract
BACKGROUND Medical devices play an important role in the diagnosis, prevention, treatment and care of diseases. However, compared to pharmaceuticals, there is no rigorous formal regulation for demonstration of benefits and exclusion of harms to patients. The medical device industry argues that the classical evidence hierarchy cannot be applied for medical devices, as randomised clinical trials are impossible to perform. This article aims to identify the barriers for randomised clinical trials on medical devices. METHODS Systematic literature searches without meta-analysis and internal European Clinical Research Infrastructure Network (ECRIN) communications taking place during face-to-face meetings and telephone conferences from 2013 to 2017 within the context of the ECRIN Integrating Activity (ECRIN-IA) project. RESULTS In addition to the barriers that exist for all trials, we identified three major barriers for randomised clinical trials on medical devices, namely: (1) randomisation, including timing of assessment, acceptability, blinding, choice of the comparator group and considerations on the learning curve; (2) difficulties in determining appropriate outcomes; and (3) the lack of scientific advice, regulations and transparency. CONCLUSIONS The present review offers potential solutions to break down the barriers identified, and argues for applying the randomised clinical trial design when assessing the benefits and harms of medical devices.

Abstract
Laparoscopic cholecystectomy (LC) is one of the first laparoscopic procedures performed by surgical trainees. This study aims to determine preoperative and/or intraoperative predictors of difficult LC and to compare complications of LC performed by trainees with that performed by trained surgeons. A cohort of 180 consecutive patients with cholelithiasis who underwent LC was analyzed. We used univariate and binary logistic regression analyses to predict factors associated with difficult LC. We compared the rate of complications of LCs performed by trainees and that performed by trained surgeons using Pearson's chi-square test. Patients with impacted stone in the neck of the gallbladder (GB) (OR, 5.0; 95% CI, 1.59-15.77), with adhesions in the Triangle of Calot (OR, 2.9; 95% CI, 1.27-6.83), or with GB rupture (OR, 3.4; 95% CI, 1.02-11.41) were more likely to experience difficult LC. There was no difference between trainees and trained surgeons in the rate of cystic artery injury (p = .144) or GB rupture (p = .097). However, operative time of LCs performed by trained surgeons was significantly shorter (median, 45 min; IQR, 30-70 min) compared with the surgical trainees' operative time (60 min; IQR, 50-90 min). Surgical trainees can perform difficult LC safely under supervision with no increase in complications albeit with mild increase in operative time.

Abstract
Background Health care providers need solid evidence based data on cost differences between alternative surgical procedures for common surgical disorders. We aimed to compare small-incision open cholecystectomy (SIOC) and laparoscopic cholecystectomy (LC) concerning costs and health-related quality of life using data from an expertise-based randomised controlled trial. Methods Patients scheduled for cholecystectomy were assigned to undergo LC or SIOC performed by surgeons in two different expert groups. Total costs were calculated in USD. Reusable instruments were assumed for the cost analysis. Quality of life was measured using the EuroQol 5-D 3-L (EQ 5-D-3L), at five postoperative time points and calculated to Area Under Curve (AUC) for 1 year postoperatively. Two hospitals participated in the trial, which included both emergency and elective surgery. Results Of 477 patients that underwent a cholecystectomy during the study period, 355 (74.9%) were randomised and 323 analysed, 172 LC and 151 SIOC patients. Both direct and total costs were less for SIOC than for LC patients. The total costs were 5429 (4293–6932) USD for LC and 4636 (3905–5746) USD for SIOC, P = 0.001. The quality of life index did not differ between the LC and SIOC groups at any time. Median values (25th and 75th percentiles (p25-p75)) for AUC at 1 year were as follows: 349 (337–351) for LC and 349 (338–350) for SIOC. Conclusions In this expertise-based randomised controlled trial LC was a more costly procedure and quality of life did not differ after SIOC and LC.

Abstract
BACKGROUND Fatigue and unintentional weight loss are two of the commonest symptoms experienced by people with advanced progressive illness. Appropriate interventions may bring considerable improvements in function and quality of life to seriously ill people and their families, reducing physical, psychological and spiritual distress. OBJECTIVES To conduct an overview of the evidence available on the efficacy of interventions used in the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness by reviewing the evidence contained within Cochrane reviews. METHODS We searched the Cochrane Database of Systematic Reviews (CDSR) for all systematic reviews evaluating any interventions for the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness (The Cochrane Library 2010, Issue 8). We reviewed titles of interest by abstract. Where the relevance of a review remained unclear we reached a consensus regarding the relevance of the participant group and the outcome measures to the overview. Two overview authors extracted the data independently using a data extraction form. We used the measurement tool AMSTAR (Assessment of Multiple SysTemAtic Reviews) to assess the methodological quality of each systematic review. MAIN RESULTS We included 27 systematic reviews (302 studies with 31,833 participants) in the overview. None of the included systematic reviews reported quantitative data on the efficacy of interventions to manage fatigue or weight loss specific to people with advanced progressive illness. All of the included reviews apart from one were deemed of high methodological quality. For the remaining review we were unable to ascertain the methodological quality of the research strategy as it was described. None of the systematic reviews adequately described whether conflict of interests were present within the included studies. Management of fatigueAmyotrophic lateral sclerosis/motor neuron disease (ALS/MND) - we identified one systematic review (two studies and 52 participants); the intervention was exercise.Cancer - we identified five systematic reviews (116 studies with 17,342 participants); the pharmacological interventions were eicosapentaenoic acid (EPA) and any drug therapy for the management of cancer-related fatigue and the non pharmacological interventions were exercise, interventions by breast care nurses and psychosocial interventions.Chronic obstructive pulmonary disease (COPD) - we identified three systematic reviews (59 studies and 4048 participants); the interventions were self management education programmes, nutritional support and pulmonary rehabilitation.Cystic fibrosis - we identified one systematic review (nine studies and 833 participants); the intervention was physical training.Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) - we identified two systematic reviews (21 studies and 748 participants); the interventions were progressive resistive exercise and aerobic exercise.Multiple sclerosis (MS) - we identified five systematic reviews (23 studies and 1502 participants); the pharmacological interventions were amantadine and carnitine. The non pharmacological interventions were diet, exercise and occupational therapy.Mixed conditions in advanced stages of illness - we identified one systematic review (five studies and 453 participants); the intervention was medically assisted hydration. Management of weight lossALS/MND - we identified one systematic review but no studies met the inclusion criteria for the systematic review; the intervention was enteral tube feeding.Cancer - we identified three systematic reviews with a fourth systematic review also containing extractable data on cancer (66 studies and 5601 participants); the pharmacological interventions were megestrol acetate and eicosapentaenoic acid (EPA) (this systematic review is also included in the cancer fatigue section above). The non pharmacological interventions were enteral tube feeding and non invasive interventions for patients with lung cancer.COPD - we identified one systematic review (59 studies and 4048 participants); the intervention was nutritional support. This systematic review is also included in the COPD fatigue section.Cystic fibrosis - we identified two systematic reviews (three studies and 131 participants); the interventions were enteral tube feeding and oral calorie supplements.HIV/AIDS - we identified four systematic reviews (42 studies and 2071 participants); the pharmacological intervention was anabolic steroids. The non pharmacological interventions were nutritional interventions, progressive resistive exercise and aerobic exercise. Both of the systematic reviews on exercise interventions were also included in the HIV/AIDS fatigue section.MS - we found no systematic reviews which considered interventions to manage unintentional weight loss for people with a clinical diagnosis of multiple sclerosis at any stage of illness.Mixed conditions in advanced stages of illness - we identified two systematic reviews (32 studies and 4826 participants); the interventions were megestrol acetate and medically assisted nutrition. AUTHORS' CONCLUSIONS There is a lack of robust evidence for interventions to manage fatigue and/or unintentional weight loss in the advanced stage of progressive illnesses such as advanced cancer, heart failure, lung failure, cystic fibrosis, multiple sclerosis, motor neuron disease, Parkinson's disease, dementia and AIDS. The evidence contained within this overview provides some insight into interventions which may prove of benefit within this population such as exercise, some pharmacological treatments and support for self management.Researchers could improve the methodological quality of future studies by blinding of outcome assessors. Adopting uniform reporting mechanisms for fatigue and weight loss outcome measures would also allow the opportunity for meta-analysis of small studies.Researchers could also improve the applicability of recommendations for interventions to manage fatigue and unintentional weight loss in advanced progressive illness by including subgroup analysis of this population within systematic reviews of applicable interventions.More research is required to ascertain the best interventions to manage fatigue and/or weight loss in advanced illness. There is a need for standardised reporting of these symptoms and agreement amongst researchers of the minimum duration of studies and minimum percentage change in symptom experience that proves the benefits of an intervention. There are, however, challenges in providing meaningful outcome measurements against a background of deteriorating health through disease progression. Interventions to manage these symptoms must also be mindful of the impact on quality of life and should be focused on patient-orientated rather than purely disease-orientated experiences for patients. Systematic reviews and primary intervention studies should include the impact of the interventions on standardised validated quality of life measures.

Methodological overview of systematic reviews to establish the evidence base for emergency general surgery. Br J Surg 2017; 104:513-524. [PMID: 28295254 PMCID: PMC5363346 DOI: 10.1002/bjs.10476] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Revised: 08/23/2016] [Accepted: 11/30/2016] [Indexed: 12/18/2022]
Abstract
BACKGROUND The evidence for treatment decision-making in emergency general surgery has not been summarized previously. The aim of this overview was to review the quantity and quality of systematic review evidence for the most common emergency surgical conditions. METHODS Systematic reviews of the most common conditions requiring unplanned admission and treatment managed by general surgeons were eligible for inclusion. The Centre for Reviews and Dissemination databases were searched to April 2014. The number and type (randomized or non-randomized) of included studies and patients were extracted and summarized. The total number of unique studies was recorded for each condition. The nature of the interventions (surgical, non-surgical invasive or non-invasive) was documented. The quality of reviews was assessed using the AMSTAR checklist. RESULTS The 106 included reviews focused mainly on bowel conditions (42), appendicitis (40) and gallstone disease (17). Fifty-one (48·1 per cent) included RCTs alone, 79 (74·5 per cent) included at least one RCT and 25 (23·6 per cent) summarized non-randomized evidence alone. Reviews included 727 unique studies, of which 30·3 per cent were RCTs. Sixty-five reviews compared different types of surgical intervention and 27 summarized trials of surgical versus non-surgical interventions. Fifty-seven reviews (53·8 per cent) were rated as low risk of bias. CONCLUSION This overview of reviews highlights the need for more and better research in this field.

Abstract
Cholelithiasis is one of the commonest diseases in gastroenterology. Remarkable improvements in therapeutic modalities for cholelithiasis and its complications are evident. The Japanese Society of Gastroenterology has revised the evidence-based clinical practice guidelines for cholelithiasis. Forty-three clinical questions, for four categories-epidemiology and pathogenesis, diagnosis, treatments, and prognosis and complications-were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012. The guidelines were developed with use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. This article preferentially describes the clinical management of cholelithiasis and its complications. Following description of the diagnosis performed stepwise through imaging modalities, treatments of cholecystolithiasis, choledocholithiasis, and hepatolithiasis are introduced along with a flowchart. Since there have been remarkable improvements in endoscopic treatments and surgical techniques, the guidelines ensure flexibility in choices according to the actual clinical environment. The revised clinical practice guidelines are appropriate for use by clinicians in their daily practice.

Abstract
OBJECTIVE There are considerable variations in cholecystectomy rates between countries, but it remains unsettled whether high cholecystectomy rates prevent future gallstone complications by reducing the gallstone prevalence. The aims of this study were to investigate the regional differences in cholecystectomy rates and their relation to the incidence of gallstone complications. MATERIAL AND METHODS Nation-wide registry-based study of the total number of cholecystectomies in Sweden between 1998 and 2013. Data were obtained from the Swedish Inpatient Registry covering the entire population and subdivided for by the 21 different counties. Indications for the procedure were prospectively collected during the years 2006-2013 in the National Registry for Gallstone Surgery and ERCP. The detailed demography of the total number of patients undergoing cholecystectomy and its relation to the respective indications were analysed by linear regression. RESULTS The annual rates of cholecystectomy in the Swedish counties ranged from 100 to 207 per 100,000 inhabitants, with a mean of 157 (95% CI 145-169). The majority of cholecystectomies were done in females based on the indication biliary colic, with a peak incidence in younger ages. Cholecystectomies performed due to gallstone complications, pancreatitis and cholecystitis, were mainly carried out in the older age groups. No significant relationship could be demonstrated between cholecystectomy rates in the different regions and the respective incidences of gallstone complications. CONCLUSIONS There are wide regional variations in cholecystectomy rates in Sweden. The present study does not give support that frequent use of cholecystectomy in uncomplicated gallstone disease prevents future gallstone complications.

Abstract
BACKGROUND For cholecystectomy, multiport laparoscopy is the recommended surgical approach. Single-port laparoscopy (SPL) was introduced to reduce postoperative pain and provide better cosmetic results, but has technical disadvantages. Robotic SPL (RSPL) was developed to overcome these disadvantages. In this prospective study, we aim to describe intraoperative results and postoperative outcomes of RSPL cholecystectomies and evaluate technical aspects of the technique. METHODS A prospective database of all patients who underwent a RSPL cholecystectomy between January 2012 and December 2014 was analyzed. Intraoperative results and postoperative complications were evaluated. RESULTS A total of 27 patients underwent RSPL cholecystectomy. Median age was 59 (20-78) years and median body mass index was 25 (19-35) kg/m2. The majority of patients had American Society of Anesthesiologists (ASA) II classification (67%) and 89% underwent surgery for cholecystolithiasis or cholecystitis. The median operating time was 81 (41-115) minutes. Conversion to a multiport procedure occurred in 2; one due to insufficient length of the robotic instruments. In the second and third patients, conversion to an open procedure was necessary due to inadequate exposure caused by liver cirrhosis and purulent ascites, respectively. In seven procedures, spill occurred due to rupture of the gallbladder. Postoperative complications occurred in 4 patients, including 1 bleeding (no reintervention), 1 peritonitis, and 2 wound infections. After a median follow-up of 33 (10-44) months, 5 (19%) trocar-site hernias were seen. CONCLUSION RSPL cholecystectomy is feasible, however, encountered by technical challenges due to inadequate length of the nonwristed robotic instruments. A high incidence of gallbladder rupture and trocar-site hernias may limit its application.

Abstract
Background: Laparoscopic cholecystectomy is widely used for cholelithiasis. Abdominal ultrasonography often precedes this operation and can prove diagnosis, as well as helps in showing possible complications during the perioperative period. Aim: Evaluate the description of variables of gallbladder and bile ducts present in reports of preoperative abdominal ultrasonography in cholelithiasis comparing with surgical findings. Methods: Were studied 91 patients who underwent elective laparoscopic cholecystectomy with previous abdominal ultrasonography. Variables such as identification and amount of gallstones involved were evaluated, both in preoperative ultrasonography and during surgery to evaluate sensitivity, specificity, concordance and positive and negative predictive values. Results: The reports did not mention diameter of vesicular light (98.9%), organ distension (62.6%), gallstone sizes (58.2%), wall thickness (41.8%) and evaluation of the common bile duct (39.6%). Ultrasound had high values for sensitivity, consistency and positive predictive value for identifying the presence/absence of gallstones: 98.8%, 96.7% and 97.8% respectively. As for the amount of stones, ultrasonography showed agreement in 82.7%, negative predictive value in 89.1% and specificity in 87.7%, with lower values for sensitivity (68.2%) and positive predictive value (65.2%). Conclusions: The ultrasound reports were flawed in standardization. Significant percentage of them did not have variables that could predict perioperative complications and surgical conversion.

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

Abstract
Background and Objectives: Within the past few years, there has been a push for an even more minimally invasive approach to biliary disease with the adoption of single-incision laparoscopic cholecystectomy. We sought to compare 4 individual surgeon experiences to define whether there exists a learning curve for performing single-incision laparoscopic cholecystectomy. Methods: We performed a retrospective review 290 single-incision laparoscopic cholecystectomies performed by a group of general surgeons, with varying levels of experience and training, at 3 institutions between May 2008 and September 2010. The procedure times were recorded for each single-incision laparoscopic cholecystectomy, ordered chronologically for each surgeon, and subsequently plotted on a graph. The patients were also combined into cohorts of 5 and 10 cases to further evaluate for signs of improvement in operative efficiency. Results: Of the 4 surgeons involved in the study, only 1 (surgeon 4, laparoscopic fellowship trained with <5 years' experience) confirmed the presence of a learning curve, reaching proficiency within the first 15 cases performed. The other surgeons had more variable procedure times, which did not show a distinct trend. When we evaluated the cases by cohorts of 5 cases, surgeon 4 had a significant difference between the first and last cohort. Increased body mass index resulted in a slightly longer operative time (P < .0063). The conversion rate to multiport laparoscopic surgery was 3.1%. Conclusions: Our results indicate that among experienced general surgeons, there does not seem to be a significant learning curve when transitioning from conventional laparoscopic cholecystectomy to single-incision laparoscopic cholecystectomy. The least experienced surgeon in the group, surgeon 4, appeared to reach proficiency after 15 cases. Greater than 5 years of experience in laparoscopic surgery appears to provide surgeons with a sufficient skill set to obviate the need for a single-incision laparoscopic cholecystectomy learning curve.

Abstract
AIM: To review current applications of the laparoscopic surgery while highlighting the standard procedures across different fields.
METHODS: A comprehensive search was undertaken using the PubMed Advanced Search Builder. A total of 321 articles were found in this search. The following criteria had to be met for the publication to be selected: Review article, randomized controlled trials, or meta-analyses discussing the subject of laparoscopic surgery. In addition, publications were hand-searched in the Cochrane database and the high-impact journals. A total of 82 of the findings were included according to matching the inclusion criteria. Overall, 403 full-text articles were reviewed. Of these, 218 were excluded due to not matching the inclusion criteria.
RESULTS: A total of 185 relevant articles were identified matching the search criteria for an overview of the current literature on the laparoscopic surgery. Articles covered the period from the first laparoscopic application through its tremendous advancement over the last several years. Overall, the biggest advantage of the procedure has been minimizing trauma to the abdominal wall compared with open surgery. In the case of cholecystectomy, fundoplication, and adrenalectomy, the procedure has become the gold standard without being proven as a superior technique over the open surgery in randomized controlled trials. Faster recovery, reduced hospital stay, and a quicker return to normal activities are the most evident advantages of the laparoscopic surgery. Positive outcomes, efficiency, a lower rate of wound infections, and reduction in the perioperative morbidity of minimally invasive procedures have been shown in most indications.
CONCLUSION: Improvements in surgical training and developments in instruments, imaging, and surgical techniques have greatly increased safety and feasibility of the laparoscopic surgical procedures.

Abstract
OBJECTIVES Prior reports have linked patient transmission of carbapenem-resistant Enterobacteriaceae (CRE, or "superbug") to endoscopes used during endoscopic retrograde cholangiopancreatography (ERCP). We performed a decision analysis to measure the cost-effectiveness of four competing strategies for CRE risk management. METHODS We used decision analysis to calculate the cost-effectiveness of four approaches to reduce the risk of CRE transmission among patients presenting to the hospital for symptomatic common bile duct stones. The strategies included the following: (1) perform ERCP followed by US Food and Drug Administration (FDA)-recommended endoscope reprocessing procedures; (2) perform ERCP followed by "endoscope culture and hold"; (3) perform ERCP followed by ethylene oxide (EtO) sterilization of the endoscope; and (4) stop performing ERCP in lieu of laparoscopic cholecystectomy (LC) with common bile duct exploration (CBDE). Our outcome was incremental cost per quality-adjusted life year (QALY) gained. RESULTS In the base-case scenario, ERCP with FDA-recommended endoscope reprocessing was the most cost-effective strategy. Both the ERCP with culture and hold ($4,228,170/QALY) and ERCP with EtO sterilization ($50,572,348/QALY) strategies had unacceptable incremental costs per QALY gained. LC with CBDE was dominated, being both more costly and marginally less effective vs. the alternatives. In sensitivity analysis, ERCP with culture and hold became the most cost-effective approach when the pretest probability of CRE exceeded 24%. CONCLUSIONS In institutions with a low CRE prevalence, ERCP with FDA-recommended reprocessing is the most cost-effective approach for mitigating CRE transmission risk. Only in settings with an extremely high CRE prevalence did ERCP with culture and hold become cost-effective.

Abstract
INTRODUCTION Since the widespread adoption of laparoscopic techniques in biliary surgery, the incidence of bile duct injures (BDI) has not significantly declined despite increased operative experience and recognition of the critical view of safety (CVS) method for anatomic identification. We hypothesized that operative approaches in clinical practice may vary from well-described technical recommendations. The objective of this study was to access how practicing surgeons commonly identify anatomy during laparoscopic cholecystectomy (LC). METHODS We performed a cohort study assessing practices in biliary surgery among current practicing surgeons. Surgeons belonging to the Midwest Surgical Association and the Society of American Gastrointestinal and Endoscopic Surgeons were surveyed. Items surveyed include preferred methods for cystic duct identification, recognition of the CVS, and use of intraoperative imaging. RESULTS In total, 374 of 849 surgeons responded. The CVS was not correctly identified by 75 % of surgeons descriptively and by 21 % of surgeons visually. 56 % of surgeons practiced the infundibular method for identification of the cystic duct; 27 % practiced the CVS method. Intraoperative cholangiography was used by 16 % and laparoscopic ultrasound by <1 %. CONCLUSION A majority of surgeons preferably do not use the CVS method of identification during LC. A large percentage of practicing surgeons are unable to describe or visually identify the CVS. These results suggest an urgent need to reexamine the tenets of how LC is being taught and disseminated and present a clear target for improvement to reduce BDI.

Abstract
BACKGROUND This review discusses current insights with regard to biliary tract management during and after acute biliary pancreatitis. METHODS A MEDLINE and EMBASE search was done and studies were selected based on methodological quality and publication date. The recommendations of recent guidelines are incorporated in this review. In absence of consensus in the literature, expert opinion is expressed. RESULTS There is no role for early endoscopic retrograde cholangiopancreatography (ERCP) in patients with (predicted) mild biliary pancreatitis to improve outcome. In case of persisting choledocholithiasis, ERCP with stone extraction is scheduled electively when the acute event has subsided. Whether early ERCP with sphincterotomy is beneficial in patients with predicted severe pancreatitis remains subject to debate. Regardless of disease severity, in case of concomitant cholangitis urgent endoscopic sphincterotomy (ES) is recommended. As a definitive treatment to reduce the risk of recurrent biliary events in the long term, ES is inferior to cholecystectomy and should be reserved for patients considered unfit for surgery. After severe biliary pancreatitis, cholecystectomy should be postponed until all signs of inflammation have subsided. In patients with mild pancreatitis, cholecystectomy during the primary admission reduces the risk of recurrent biliary complications. CONCLUSION Recent research has provided valuable data to guide biliary tract management in the setting of acute biliary pancreatitis with great value and benefit for patients and clinicians. Some important clinical dilemmas remain, but it is anticipated that on-going clinical trials will deliver some important insights and additional guidance soon.

Abstract
The history of pancreatic cancer surgery, though fraught with failure and setbacks, is punctuated by periods of incremental progress dependent upon the state of the art and the mettle of the surgeons daring enough to attempt it. Surgical anesthesia and the aseptic techniques developed during the latter half of the 19(th) century were instrumental in establishing a viable setting for pancreatic surgery to develop. Together, they allowed for bolder interventions and improved survival through the post-operative period. Surgical management began with palliative procedures to address biliary obstruction in advanced disease. By the turn of the century, surgical pioneers such as Alessandro Codivilla and Walther Kausch were demonstrating the technical feasibility of pancreatic head resections and applying principles learned from palliation to perform complicated anatomical reconstructions. Allen O. Whipple, the namesake of the pancreaticoduodenectomy (PD), was the first to take a systematic approach to refining the procedure. Perhaps his greatest contribution was sparking a renewed interest in the surgical management of periampullary cancers and engendering a community of surgeons who advanced the field through their collective efforts. Though the work of Whipple and his contemporaries legitimized PD as an accepted surgical option, it was the establishment of high-volume centers of excellence and a multidisciplinary approach in the later decades of the 20(th) century that made it a viable surgical option. Today, pancreatic surgeons are experimenting with minimally invasive surgical techniques, expanding indications for resection, and investigating new methods for screening and early detection. In the future, the effective management of pancreatic cancer will depend upon our ability to reliably detect the earliest cancers and precursor lesions to allow for truly curative resections.

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

Abstract
BACKGROUND AND AIMS The feasibility of incidental cholecystectomy during colorectal cancer (CRC) surgery has not been determined as yet. We aimed to investigate the feasibility of incidental cholecystectomy during CRC surgery. METHODS The clinicopathologic data of patients who underwent CRC surgery between January 2004 and May 2011 were assessed. Patients with asymptomatic cholelithiasis were divided into groups that did and did not undergo incidental cholecystectomy. Their in-hospital morbidity and long-term biliary complications were compared. RESULTS Of the 282 patients identified, 143 (50.7%) underwent incidental cholecystectomy and 139 (49.3%) were observed without cholecystectomy. The two groups were similar in clinical characteristics, except for gender and operation time. Only one patient (0.7%) in the cholecystectomy group experienced an intraoperative biliary complication. There was no significant difference in overall in-hospital morbidity between the two groups. After a median follow-up period of 33 months, long-term biliary complications developed in 12 patients (8.6%) in the observation group, with 9 undergoing cholecystectomy. CONCLUSIONS Incidental cholecystectomy was not associated with increased postoperative morbidity, whereas previously asymptomatic patients were at substantial long-term risk of becoming symptomatic. Thus, in the absence of clear contraindications, concomitant cholecystectomy might be a desirable treatment option during CRC surgery in patients with asymptomatic gallstones.

Abstract
BACKGROUND This population-level health service study aimed to address whether hospitals assure the same quality of care to people in equal need, i.e. to see if any associations exist between social determinants and adherence to four hospital process indicators clearly identified as being linked to better health outcomes for patients. PARTICIPANTS This was a retrospective cohort study based on administrative data collected in the Veneto Region (northeast Italy). We included residents of the Veneto Region hospitalized for ST-segment elevation myocardial infarction (STEMI) or acute myocardial infarction (AMI), hip fracture, or cholecystitis, and women giving birth, who were discharged from any hospital operating under the Veneto Regional Health Service between January 2012 and December 2012. METHOD The following quality indicator rates were calculated: patients with STEMI-AMI treated with percutaneous coronary intervention, elderly patients with hip fractures who underwent surgery within 48 h of admission, laparoscopic cholecystectomies and women who underwent cesarean section. A multilevel, multivariable logistic regression analyses were conducted to test the association between age, gender, formal education or citizenship and the quality of hospital care processes. RESULTS All the inpatient hospital care process quality indicators measured were associated with an undesirable number of disparities concerning the social determinants. CONCLUSION Monitoring the evidence-based hospital health care process indicators reveals undesirable disparities. Administrative data sets are of considerable practical value in broad-based quality assessments and as a screening tool, also in the health disparities domain.

Abstract
PURPOSE Currently, most ESRD patients are treated with open surgical technique or with laparoscopic technique. In this study, we examined the role of the ureteroscope-assisted "Mini-Perc" technique versus the modified open surgery in the treatment of ESRD in a prospective randomized manner. METHODS A total of 72 patients with chronic renal failure were prospectively randomized for the ureteroscope-assisted "Mini-Perc" technique or modified open surgery. Intraoperative and postoperative morbidity, incision size, dose of local anesthesia, operative time, hospital stay, and initial catheter survival and follow-up were compared for both methods. RESULTS "Mini-Perc" group was associated with shorter incision size, operative time, and hospital stay, with lower dose of local anesthesia and incidence of bloody ascites. Two of five patients with the history of abdominal surgery in "Mini-Perc" group required adhesiolysis under direct vision of telescope. All adhesions were easily dissected. All complications of leakage (8.1 %) and incisional hernia (2.7 %) occurred in the open surgery group, but a difference of no significant value with "Mini-Perc" group (p = 0.2400, p = 1.0000). There was no any other significant difference in common complications between two groups. After 2 years of follow-up, 54 patients (75 %) survived with their initial PD catheter. The overall death was 5 (6.9 %). CONCLUSIONS Compared to modified open surgical technique, the ureteroscope-assisted "Mini-Perc" technique can be used to achieve the same clinical efficacy for placement of peritoneal dialysis catheters in ESRD patients, and it carries minimal morbidity.

Evidence-based medicine in daily surgical decision making: a survey-based comparison between the UK and Germany. Eur Surg Res 2014; 54:14-23.

Abstract
BACKGROUND Evidence-based medicine (EbM) is a vital part of reasonable and conclusive decision making for clinicians in daily clinical work. To analyze the knowledge and the attitude of surgeons towards EbM, a survey was performed in the UK and Germany. METHODS A web-based questionnaire was distributed via mailing lists from the Royal College of Surgeons of England (RCSE) and the Berufsverband Deutscher Chirurgen (BDC). Our primary aim was to get information about knowledge of EbM amongst German and British surgeons. RESULTS A total of 549 individuals opened the questionnaire, but only 198 questionnaires were complete and valid for analysis. In total, 40,000 recipients were approached via the mailing lists of the BDC and RCSE. The response rate was equally low in both countries. On a scale from 1 (unimportant) to 10 (very important), all participants rated EbM as very important for daily clinical decision making (7.3 ± 1.9) as well as for patients (7.8 ± 1.9) and the national health system (7.8 ± 1.9). On a scale from 1 (unimportant) to 5 (very important), systematic reviews (4.6 ± 0.6) and randomized controlled trials (4.6 ± 0.6) were identified as the highest levels of study designs to enhance evidence in medicine. British surgeons considered EbM to be more important in daily clinical work when compared to data from German surgeons (7.9 ± 1.6 vs. 6.7 ± 2.1, p < 0.001). Subgroup analysis showed different results in some categories; however, a pattern to explain the differences was not evident. Personal requirements expressed in a free text field emphasized the results and reflected concerns such as broad unwillingness and lack of interdisciplinary approaches for patients (n = 59: 25 in the UK and 34 in Germany). CONCLUSION The overall results show that EbM is believed to be important by surgeons in the UK and Germany. However, perception of EbM in the respective health system (UK vs. Germany) may be different. Nonetheless, EbM is an important tool to navigate through daily clinical problems although a discrepancy between the knowledge of theoretical abstract terms and difficulties in implementing EbM in daily clinical work has been detected. The provision of infrastructure, courses and structured education as a permanent instrument will advance the knowledge, application and improvement of EbM in the future.

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