- The SARS-CoV-2 pandemic has had a significant impact on healthcare delivery. As resources are reallocated, surgery for benign conditions such as gallstone disease is often given low priority. We do not know how this has affected the risk of patients with uncomplicated gallstone disease to develop acute cholecystitis, biliary pancreatitis, or obstructive jaundice.The study was based on the population-based Swedish Register of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography. The period prior to the first cases of COVID-19 in Sweden, that is, April 2015-March 2020, was compared to the period April 2020-March 2021 during the pandemic. Stratification was made for factors potentially related to priority decisions.Altogether, 78,211 procedures were performed during the period of the study. The ratio of procedures performed during April 2020-March 2021 in the previous 5 years was 0.960 (p = 0.113). The ratio of procedures on patients aged <65 years was 0.945 (p = 0.008), on patients aged 65-80 years was 0.964 (p = 0.423), on patients aged >80 years was 1.336 (p = 0.025), on men was 1.001 (p = 0.841), on women was 0.934 (p = 0.006), on procedures completed laparoscopically was 0.964 (p = 0.190), on procedures completed with open approach was 0.659 (p = 0.044), on acute procedures was 1.218 (p = 0.016), on planned procedures was 0.791 (p < 0.001), on procedures performed for biliary colic was 0.808 (p < 0.001), on procedures performed for acute cholecystitis was 1.274 (p = 0.012), for biliary pancreatitis was 1.192 (p = 0.037), and for obstructive jaundice was 1.366 (p = 0.008).The COVID-19 has had a great impact on how gallstone surgery has been organized over the last 2 years. The decreased number of planned procedures probably reflects the reallocation of resources during the pandemic. However, whether the increasing number of acute procedures is the result of postponed planned surgery or a continuation of a long-term trend toward more acute surgery remains unanswered. Further studies are needed to assess and evaluate how this has affected public health and health economics.

- OBJECTIVE: To investigate how simulator training and non-technical factors affect laparoscopic performance among residents in obstetrics and gynecology. DESIGN: In this prospective study, trainees were randomized into three groups. The first group was allocated to proficiency-based training in the LapSimGyn(®) virtual reality simulator. The second group received additional structured mentorship during subsequent laparoscopies. The third group served as control group. At baseline an operation was performed and visuospatial ability, flow and self-efficacy were assessed. All groups subsequently performed three tubal occlusions. Self-efficacy and flow were assessed before and/or after each operation. SETTING: Simulator training was conducted at the Center for Advanced Medical Simulation and Training, Karolinska University Hospital. Sterilizations were performed at each trainee's home clinic. POPULATION: Twenty-eight trainees/residents from 21 hospitals in Sweden were included. METHODS/MAIN OUTCOME MEASURES: Visuospatial ability was tested by the Mental Rotation Test-A. Flow and self-efficacy were assessed by validated scales and questionnaires. Laparoscopic performance was measured as the duration of surgery. Visuospatial ability, self-efficacy and flow were correlated to the laparoscopic performance using Spearman's correlations. Differences between groups were analyzed by the Mann-Whitney U-test. RESULTS: No differences across groups were detected at baseline. Self-efficacy scores before and flow scores after the third operation were significantly higher in the trained groups. Duration of surgery was significantly shorter in the trained groups. Flow and self-efficacy correlate positively with laparoscopic performance. CONCLUSIONS: Simulator training and non-technical factors appear to improve the laparoscopic performance among trainees/residents in obstetrics and gynecology.

- Background: Bile duct injury (BDI) is a severe complication following cholecystectomy. Early recognition and treatment of BDI has been shown to reduce costs and improve patients' quality of life. The aim of this study was to assess the effect and cost-effectiveness of routine versus selective intraoperative cholangiography (IOC) in cholecystectomy. Methods: A systematic review and meta-analysis, combined with a health economic model analysis in the Swedish setting, was performed. Costs per quality-adjusted life-year (QALY) for routine versus selective IOC during cholecystectomy for different scenarios were calculated. Results: In this meta-analysis, eight studies with more than 2 million patients subjected to cholecystectomy and 9000 BDIs were included. The rate of BDI was estimated to 0.36 per cent when IOC was performed routinely, compared with to 0.53 per cent when used selectively, indicating an increased risk for BDI of 43 per cent when IOC was used selectively (odds ratio 1.43, 95 per cent c.i. 1.22 to 1.67). The model analysis estimated that seven injuries were avoided annually by routine IOC in Sweden, a population of 10 million. Over a 10-year period, 33 QALYs would be gained at an approximate net cost of (sic)808 000 , at a cost per QALY of about (sic)24 900. Conclusion: Routine IOC during cholecystectomy reduces the risk of BDI compared with the selective strategy and is a potentially cost-effective intervention.

- OBJECTIVES: To describe the process of initiating and organizing a nationwide validated web-based quality registry of gallstone surgery and endoscopic retrograde cholangiopancreatography (ERCP) and to present some clinical data and the impact the registry has had on the clinical treatment of gallstones.DESIGN: Observational, population-based registry study.SETTING: Data from the nationwide Swedish Registry of Gallstone Surgery and ERCP (GallRiks).PATIENTS: From May 1, 2005, to December 31, 2011, 63 685 cholecystectomies (laparoscopic and open) and 37 860 ERCPs have been prospectively registered in GallRiks.INTERVENTIONS: Cholecystectomies, laparoscopic or conventional, as well as ERCP in a population-based setting.MAIN OUTCOME MEASURES: Registrations of all cholecystectomies and ERCPs are performed online by the surgeon or endoscopist. Thirty-day follow-up of both gallstone surgery and ERCP is mandatory, as is an additional 6-month follow-up of the cholecystectomies. Scores on the 36-Item Short Form Health Survey are registered preoperatively and 6 months postoperatively in elective cholecystectomies at selected units.RESULTS: The 30-day overall complication rate is 6.1% in elective cholecystectomy, 11.2% in urgent cholecystectomy, and 12.0% following ERCP. The use of antibiotic and thromboembolic prophylaxis in elective laparoscopic cholecystectomy in Sweden has decreased by 8.7% and 17.8% (2006-2011), respectively, mainly owing to presentation of GallRiks data both at meetings and published in peer-reviewed publications. The large database has also enabled several research projects, including one demonstrating that the intention to perform intraoperative cholangiography reduced the risk of death after cholecystectomy. The database has reached greater than 90% national coverage and is continuously validated.CONCLUSIONS: GallRiks is a validated national quality registry for gallstone surgery and ERCP, serving as a base for audit of gallstone disease treatment. It also provides a database for clinical research.

- BACKGROUND: Rendezvous intraoperative endoscopic retrograde cholangiography (RV-IOERC), also called guidewire-facilitated IOERC, is one of the single-stage options available for managing common bile duct stones (CBDS) during laparoscopic cholecystectomy. The objective of this study is to investigate procedure-related complications in IOERC patients and stone clearance.METHODS: All patients who underwent IOERC between January 2000 and December 2009 were identified from the local registry of Karolinska University Hospital in Huddinge. Medical charts and ERC reports were studied, and descriptive statistics were obtained. Outcomes were procedure-related complications, especially post-ERCP pancreatitis (PEP), stone clearance, and mortality.RESULTS: 307 patients were identified. In 264 of the patients, the rendezvous cannulation technique was successful (86 %); in the remaining 43 patients, conventional cannulation technique was necessary. In total, PEP occurred in seven patients (2.28 %). One of the PEP patients was in the rendezvous cannulated group (0.37 %), whereas six patients developed PEP in the nonrendezvous group (13.95 %, p < 0.001). The primary stone clearance rate was 88.27 % (271/307). There was no mortality within 90 days in the series.CONCLUSIONS: IOERC with RV cannulation technique for management of CBDS during laparoscopic cholecystectomy has a low PEP rate and a high stone clearance rate, making it a safe and feasible method for removing CBDS. However, the technique requires logistics to perform IOERC in the operating theater. The present data suggest that IOERC with RV cannulation is superior to conventional cannulation with respect to risk of PEP.

- BACKGROUND: Intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) is a rare but increasingly diagnosed clinical entity. Typical cholangioscopic findings usually include intraductal protruding papillary tumors that secrete mucus.METHODS: Clinical, radiological and histopathological data of seven consecutive patients who were found to have IPMN-B were analyzed.RESULTS: Six of the seven patients presented with obstructive jaundice/cholangitis as the presenting complaint. ERCP and other imaging were equivocal in five of these patients and peroral cholangioscopy (POCS, single-operator cholangioscopy system) was performed. This revealed mucin-producing intraductal tumors with numerous frond-like papillary projections; a macroscopic appearance consistent with IPMN-B. Preoperative biopsy revealed adenoma, with low-grade dysplasia in two patients and high-grade dysplasia in three. Three patients underwent Whipple resection; one underwent total pancreatectomy with left hepatectomy, one patient a pancreas preserving duodenectomy with common bile duct reimplantation and one patient an extended right hepatectomy. These patients were found to have IPMN-B with adenomatous changes with varying grades of dysplasia and even cholangiocarcinoma on final histopathology. One patient first underwent endoscopic papillectomy and on follow-up was found to have cholangiocarcinoma with metastases to the liver.CONCLUSION: POCS can be a key diagnostic investigation in the evaluation of patients with papillary tumors of the bile duct. IPMN-B has a heterogenous pathology and varying grades of dysplasia and even carcinoma may exist in the same patient. Surgical management should be radical and based on tumor extent.

- Background: Although cholecystectomy incidence is known to be high after Roux-en-Y gastric bypass (RYGB) surgery, the actual increase in incidence is not known. Furthermore, the outcome of cholecystectomy after RYGB is not known.Objectives: To estimate cholecystectomy incidence before and after RYGB and to compare the outcome of post-RYGB cholecystectomy with the cholecystectomy outcome in the background population.Setting: Nationwide Swedish multiregister study.Methods: The Swedish Register for Cholecystectomy and Endoscopic Retrograde Cholangiopancreatography (n = 79,386) and the Scandinavian Obesity Surgery Registry (n = 36,098) were cross-matched for the years 2007 through 2013 and compared with the National Patient Register.Results: The standardized incidence ratio for cholecystectomy before RYGB was 3.42 (2.75-4.26, P < .001); the ratio peaked at 11.4 (10.2-12.6, P < .001) 6-12 months after RYGB, which was 3.54 times the baseline level (2.78-4.49, P < .001). After 36 months, the incidence ratio had returned to baseline. The post-RYGB group demonstrated an increased risk of 30-day postoperative complications after cholecystectomy (odds ratio 2.13, 1.78-2.56; P < .001), including reoperation (odds ratio 3.84, 2.76-5.36; P < .001), compared with the background population. The post-RYGB group also demonstrated a higher risk of conversion, acute cholecystectomy, and complicated gallstone disease and a slightly prolonged operative time, adjusted for age, sex, American Society of Anesthesiologists class, and previous open RYGB.Conclusion: Compared with the background population, the incidence of cholecystectomy was substantially elevated already before RYGB and increased further 6-36 months after RYGB. Previous RYGB doubled the risk of postoperative complications after cholecystectomy and almost quadrupled the risk of reoperation, even when intraoperative cholangiography was normal.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Training using laparoscopic high-fidelity simulators (LHFSs) to proficiency levels improves laparoscopic cholecystectomy skills. However, high-cost simulators and their limited availability could negatively impact residents' laparoscopic training opportunities. We aimed to assess whether motivation and surgical skill performance differ after basic skills training (BST) using a low-cost (Blackbox) versus LHFS (LapMentor) among medical students.MATERIALS AND METHODS: Sixty-three medical students from Karolinska Institutet volunteered, completing written informed consent, questionnaire regarding expectations of the simulation training, and a visuospatial ability test. They were randomized into two groups that received BST using Blackbox (n = 32) or LapMentor (n = 31). However, seven students absence resulted in 56 participants, followed by another 9 dropouts. Subsequently, after training, 47 students took up three consecutive tests using the minimally invasive surgical trainer-virtual reality (MIST-VR) simulator, finalizing a questionnaire.RESULTS: More Blackbox group participants completed all MIST-VR tests (29/31 versus 18/25). Students anticipated mastering LapMentor would be more difficult than Blackbox (P = 0.04). In those completing the simulation training, a trend toward an increase was noted in how well participants in the Blackbox group liked the simulator training (P = 0.07). Subgroup analysis of motivation and difficulty in liking the training regardless of simulator was found only in women (Blackbox [P = 0.02]; LapMentor [P = 0.06]). In the Blackbox group, the perceived difficulty of training, facilitation, and liking the Blackbox training (significant only in women) were significantly correlated with the students' performance in the MIST-simulator. No such correlations were found in the LapMentor group.CONCLUSIONS: Results indicate an important role for low-tech/low-cost Blackbox laparoscopic BST of students in an otherwise high-tech surrounding. Furthermore, experience of Blackbox BST procedures correlate with students' performance in the MIST-VR simulator, with some gender-specific differences.

Bile leakage and the number of metal clips on the cystic duct during laparoscopic cholecystectomy
- 2022
-
Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 111:2, s. 1-8

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND OBJECTIVE: The most common way of closing the cystic duct in laparoscopic cholecystectomy is by using metal clips (>80%). Nevertheless, bile leakage occurs in 0.4%-2.0% of cases, and thus causes significant morbidity. However, the optimal number of clips needed to avoid bile leakage has not been determined. The primary aim of this study was to evaluate bile leakage and post-procedural adverse events after laparoscopic cholecystectomy concerning whether two or three clips were used to seal the cystic duct.METHODS: Using a retrospective observational design, we gathered data from the Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (ERCP) (GallRiks). From 2006 until 2019, 124,818 patients were eligible for inclusion. These were nested to cohorts of 75,322 (60.3%) for uncomplicated gallstone disease and 49,496 (39.7%) with complicated gallstone disease. The cohorts were grouped by the number (i.e. two or three) of metal clips applied to the proximal cystic duct. The main outcome was 30-day bile leakage and post-procedural adverse events.RESULTS: No significant differences surfaced in the rate of bile leakage (0.8% vs 0.8%; P = .87) or post-procedural adverse events (three clips, 5.7% vs two clips, 5.4%; P = .16) for uncomplicated gallstone disease. However, for complicated disease, bile leakage (1.4% vs 1.0%; P < .001) and post-procedural adverse events (10.2% vs 8.6%; P < .001) significantly increased when the cystic duct was sealed with three clips compared with two.CONCLUSIONS: Because no differences in the rates of bile leakage or adverse events emerged in uncomplicated gallstone disease when a third clip was applied, a third clip for additional safety is not recommended in such cases. On the contrary, bile leakage and adverse events increased when a third clip was used in patients with complicated gallstone disease. This finding probably indicates a more difficult cholecystectomy rather than being caused by the third clip itself.

- The covid-19 pandemic has necessitated reallocation of health care resources. This has raised concerns about the risks associated with postponing surgery for benign conditions that are given low priority. Data from the population-based Swedish National Register for Gallstone Surgery (GallRiks) show that the total number of procedures carried out during the initial months of each wave of the pandemic decreased. This was followed by a moderate increase in the number of procedures performed for acute cholecystitis, biliary pancreatitis, and obstructive jaundice. The consequences of the delayed surgery in the community at large and how this has affected health-related quality of life for patients having their procedure postponed remain to be evaluated, but so far it does not seem to have caused a major impact on public health.
