- IMPORTANCE: Female surgeons are still in the minority worldwide, and highlighting gender differences in surgery is important in understanding and reducing inequities within the surgical specialty. Studies on different surgical procedures indicate equal results, or safer outcomes, for female surgeons, but it is still unclear whether surgical outcomes of gallstone surgery differ between female and male surgeons.OBJECTIVE: To examine the association of the surgeon's gender with surgical outcomes and operating time in elective and acute care cholecystectomies.DESIGN, SETTING, AND PARTICIPANTS: A population-based cohort study based on data from the Swedish Registry of Gallstone Surgery was performed from January 1, 2006, to December 31, 2019. The sample included all registered patients undergoing cholecystectomy in Sweden during the study period. The follow-up time was 30 days. Data analysis was performed from September 1 to September 7, 2022, and updated March 24, 2023.EXPOSURE: The surgeon's gender.MAIN OUTCOME(S) AND MEASURE(S): The association between the surgeon's gender and surgical outcomes for elective and acute care cholecystectomies was calculated with generalized estimating equations. Differences in operating time were calculated with mixed linear model analysis.RESULTS: A total of 150 509 patients, with 97 755 (64.9%) undergoing elective cholecystectomies and 52 754 (35.1%) undergoing acute care cholecystectomies, were operated on by 2553 surgeons, including 849 (33.3%) female surgeons and 1704 (67.7%) male surgeons. Female surgeons performed fewer cholecystectomies per year and were somewhat better represented at universities and private clinics. Patients operated on by male surgeons had more surgical complications (odds ratio [OR], 1.29; 95% CI, 1.19-1.40) and total complications (OR, 1.12; 95% CI, 1.06-1.19). Male surgeons had more bile duct injuries in elective surgery (OR, 1.69; 95% CI, 1.22-2.34), but no significant difference was apparent in acute care operations. Female surgeons had significantly longer operation times. Male surgeons converted to open surgery more often than female surgeons in acute care surgery (OR, 1.22; 95% CI, 1.04-1.43), and their patients had longer hospital stays (OR, 1.21; 95% CI, 1.11-1.31). No significant difference in 30-day mortality could be demonstrated.CONCLUSIONS AND RELEVANCE: The results of this cohort study indicate that female surgeons have more favorable outcomes and operate more slowly than male surgeons in elective and acute care cholecystectomies. These findings may contribute to an increased understanding of gender differences within this surgical specialty.

- BACKGROUND: Surgical safety and patient-related outcomes are important considerations when introducing new surgical techniques. Studies about the learning curves for different surgical procedures are sparse. The aim of this observational study was to evaluate the learning curve for ultrasonic fundus-first (FF) dissection in elective laparoscopic cholecystectomy (LC).METHODS: The study was conducted at eight hospitals in Sweden between 2017 and 2019. The primary endpoint was dissection time, with secondary endpoints being intra- and postoperative complication rates and the surgeon's self-assessed performance level. Participating surgeons (n = 16) were residents or specialists who performed LC individually but who had no previous experience in ultrasonic FF dissection. Each surgeon performed fifteen procedures. Video recordings from five of the procedures were analysed by two external surgeons. Patient characteristics and data on complications were retrieved from the Swedish Registry of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks).RESULTS: Dissection time decreased as experience increased (p = 0.001). Surgeons with limited experience showed more rapid progress. The overall complication rate was 14 (5.8%), including 3 (1.3%) potentially technique-related complications. Video assessment scores showed no correlation with the number of procedures performed. The self-assessed performance level was rated lower when the operation was more complicated (p < 0.001).CONCLUSIONS: Our results show that dissection time decreased with increasing experience. Most surgeons identified both favourable and unfavourable aspects of the ultrasonic FF technique. The ultrasonic device is considered well suited for gallbladder surgery, but most participating surgeons preferred to dissect the gallbladder the traditional way, beginning in the triangle of Calot. Nevertheless, LC with ultrasonic FF dissection can be considered easy to learn with a low complication rate during the initial learning curve, for both residents and specialists.

- BACKGROUND: High surgical volumes are attributed to improved quality of care, especially for extensive procedures. However, it remains unknown whether high-volume surgeons and hospitals have better results in gallstone surgery. The aim of this study was to investigate whether operative volume affects outcomes in cholecystectomies.METHODS: A registry-based cohort study was performed, based on the Swedish Registry of Gallstone Surgery. Cholecystectomies from 2006 to 2019 were included. Annual volumes for the surgeon and hospital were retrieved. All procedures were categorized into volume-based quartiles, with the highest group as reference. Low volume was defined as fewer than 20 operations per surgeon per year and fewer than 211 cholecystectomies per hospital per year. Differences in outcomes were analysed separately for elective and acute procedures.RESULTS: The analysis included 154 934 cholecystectomies. Of these, 101 221 (65.3 per cent) were elective and 53 713 (34.7 per cent) were acute procedures. Surgeons with low volumes had longer operating times (P < 0.001) and higher conversion rates in elective (OR 1.35; P = 0.023) and acute (OR 2.41; P < 0.001) operations. Low-volume surgeons also caused more bile duct injuries (OR 1.41; P = 0.033) and surgical complications (OR 1.15; P = 0.033) in elective surgery, but the results were not statistically significant for acute procedures. Low-volume hospitals had more bile duct injuries in both elective (OR 1.75; P = 0.002) and acute (OR 1.96; P = 0.003) operations, and a higher mortality rate after acute surgery (OR 2.53; P = 0.007).CONCLUSION: This study has demonstrated that operative volumes influence outcomes in cholecystectomy. The results indicate that gallstone surgery should be performed by procedure-dedicated surgeons at hospitals with high volumes of this type of benign surgery.

- Up-front cholecystectomy is the recommended therapy for acute cholecystitis (AC). However, the scientific basis for the definition of the optimal timing for surgery is scarce. The aim of this study was to analyze how the timing of surgery, after the admission to hospital for AC, affects the intra- and postoperative outcomes. Within the national Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks), all patients undergoing cholecystectomy for acute cholecystitis between January 2006 and December 2014 were identified. Data regarding patient characteristics, intra- and postoperative adverse events (AEs), bile duct injuries, and 30- and 90-day mortality risk were captured, and the correlation between the surgical timing and these parameters was analyzed. In total, data on 87,108 cholecystectomies were analyzed of which 15,760 (18.1 %) were performed due to AC. Bile duct injury, 30- and 90-day mortality risk, and intra- and postoperative AEs were significantly higher if the time from admission to surgery exceeded 4 days. The time course between surgery and complication risks seemed to be optimal if surgery was done within 2 days after hospital admission. Although AC patients operated on the day of hospital admission had a slightly increased AE rate as well as 30- and 90-day mortality rates than those operated during the interval of 1-2 days after admission, the bile duct injury and conversion rates were, in fact, significantly lower. The optimal timing of cholecystectomy for patients with AC seems to be within 2 days after admission. However, the somewhat higher frequency of AE on admission day may emphasize the importance of optimizing the patient before surgery as well as ensuring that adequate surgical resources are available.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Groin hernias in women is much less common than in men; it constitutes only 9% of all groin hernia operations. Historically, studies have been performed on men and the results applied to both genders. However, prospectively registered operations within national registers have contributed to new knowledge regarding groin hernias in women. The aim of this paper was to investigate and present a body of literature based upon the Swedish Hernia Register together with recent data from the register's annual report. Patients and Methods: PubMed and Embase were searched for studies based on the Swedish Hernia Register between 1992 and 2023. Based on the initial reading of abstracts, studies that presented results separately for women were selected and read. Recent data were acquired from the 2022 annual report of the Swedish Hernia Register. Results: A total of 73 studies of interest were identified. Of these, 52 included women, but only 19 presented separate results for women. Four themes emerged and were analysed further: emergency surgery and mortality, femoral hernias, the risk of reoperation for recurrence, and chronic pain following female groin hernia repairs. Discussion: Studies from the Swedish Hernia Register clearly describe that both the presentation of hernias and outcomes after repair differ significantly between the two genders. The differences that have been identified over the years have been incorporated into the national guidelines. Register data indicates that the guidelines have been implemented and are fairly well adhered to. As a result, significant improvements in outcomes regarding recurrences have been made for women with groin hernias in Sweden.

Forskningsöversikt (refereegranskat)abstract
- The Swedish Hernia Register (SHR) is a national quality register with more than 350,000 prospectively registered groin hernia repairs. Studies from the SHR have addressed important and clinically relevant issues within the field of laparoscopic groin hernia surgery and the aim of this paper is to present five of the most innovative patient-oriented publications including analysis of laparoscopic hernia repairs based on data retrieved from the SHR published between 2010 and 2020. After a Medline search was conducted, papers were graded and five papers were selected because of their specific nature, quality of methodology or international interest. The papers in our review studied a wide range of topics such as the risk of male infertility after mesh repair, risk of groin hernia surgery after open and minimally invasive prostatectomy, chronic pain after groin hernia surgery vs. method of repair, gender differences in risk of reoperation vs. method of repair and risk of reoperation vs. low and high molecular weight of the mesh. When gathering large amount of high-quality data, including almost total national coverage of all inguinal surgeries performed, it is possible to make valid conclusions and recommendation even on rare conditions and to sort out techniques that does not perform as intended, or does not apply to specific clinical situations. The studies above show that a laparoscopic repair is associated with a decreased risk of chronic pain for both gender to the price of a significantly higher risk of reoperation in men. The contrary is shown in women with a decreased risk of reoperation using laparoscopic repair compared to open repair.

- Background: Laparoscopic herniorrhaphy has emerged as a recognized operative method for inguinal hernia repair. This study compared the short-term results of two tension-free methods of repair: totally extraperitoneal (TEP) laparoscopic patch repair and the open Lichtenstein mesh technique. Methods: A total of 1513 men from 11 hospitals who presented with a primary unilateral inguinal hernia were randomized to one of the two methods. Operating time, short-term complications, reoperations, postoperative pain, consumption of analgesics, sick leave and time to resumption of normal physical activities were recorded. Results: Some 1371 of the 1513 men underwent surgery, 665 in the TEP group and 706 in the Lichtenstein group. The median duration of operation was 55 min for both procedures and 91.0 per cent of die patients in both groups were discharged on the day of operation. Patients in the TEP group experienced less postoperative pain (P < 0.001), consumed fewer analgesics (P < 0.001), had a shorter period of sick leave (7 versus 12 days; P < 0.001) and a shorter time to resumption of normal physical activity (20 versus 31 days; P < 0.001). Conclusion: The TEP technique took no longer to perform, and was associated with less postoperative pain, a shorter period of sick leave and a faster recovery, compared with open Lichtenstein hernia repair.

- Objective: To analyse the completeness in GallRiks of the follow-up frequency in relation to the intraoperative and postoperative outcome.Design: Population-based register study.Setting: Data from the national Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (ERCP), GallRiks.Population: All cholecystectomies and ERCPs recorded in GallRiks between 1 January 2006 and 31 December 2014.Main outcome measures: Outcomes for intraprocedural as well as postprocedural adverse events between units with either a 30-day follow-up of AO% compared with those with a less frequent follow-up (<90%).Results: Between 2006 and 2014, 162 212 cholecystectomies and ERCP procedures were registered in GallRiks. After the exclusion of non-index procedures and those with incomplete data 152 827 procedures remained for final analyses. In patients having a cholecystectomy, there were no differences regarding the adverse event rates, irrespective of the follow-up frequency. However, in the more complicated endoscopic ERCP procedures, the postoperative adverse event rates were significantly higher in those with a more frequent and complete 30-day follow-up (OR 1.92; 95% Cl 1.76 to 2.11).Conclusions: Differences in the follow-up frequency in registries affect the reported outcomes as exemplified by the complicated endoscopic ERCP procedures. A high and complete follow-up rate shall serve as an additional quality indicator for surgical registries.

Tidskriftsartikel (refereegranskat)abstract
- The Swedish Registry for cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) (GallRiks) is a validated register with high coverage. The registry started on May 1, 2005 and serves as a base for audit on gallstone disease treatment and also provides a database for clinical research. The aim of this study is to present an overview of the clinical consequences and implementations in patient care that GallRiks research may have contributed to during a 10-year period. Results from studies on GallRiks data have reduced the use of antibiotic and thromboembolic prophylaxis as well as showed the importance of intraoperative cholangiography. Furthermore, the studies on GallRiks data have most probably changed the treatment strategies in ERCP. Studies on GallRiks data have changed and improved the management of patients in Sweden who undergo gallstone surgery or ERCP.

Comparison of Sleeve Gastrectomy vs Roux-en-Y Gastric Bypass : A Randomized Clinical Trial
- 2024
-
Ingår i: JAMA Network Open. - : American Medical Association (AMA). - 2574-3805. ; 7:1
-
Tidskriftsartikel (refereegranskat)abstract
- IMPORTANCE: Laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) are widely used bariatric procedures for which comparative efficacy and safety remain unclear.OBJECTIVE: To compare perioperative outcomes in SG and RYGB.DESIGN, SETTING, AND PARTICIPANTS: In this registry-based, multicenter randomized clinical trial (Bypass Equipoise Sleeve Trial), baseline and perioperative data for patients undergoing bariatric surgery from October 6, 2015, to March 31, 2022, were analyzed. Patients were from university, regional, county, and private hospitals in Sweden (n = 20) and Norway (n = 3). Adults (aged ≥18 years) eligible for bariatric surgery with body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared) of 35 to 50 were studied.INTERVENTIONS: Laparoscopic SG or RYGB.MAIN OUTCOMES AND MEASURES: Perioperative complications were analyzed as all adverse events and serious adverse events (Clavien-Dindo grade >IIIb). Ninety-day mortality was also assessed.RESULTS: A total of 1735 of 14 182 eligible patients (12%; 1282 [73.9%] female; mean (SD) age, 42.9 [11.1] years; mean [SD] BMI, 40.8 [3.7]) were included in the study. Patients were randomized and underwent SG (n = 878) or RYGB (n = 857). The mean (SD) operating time was shorter in those undergoing SG vs RYGB (47 [18] vs 68 [25] minutes; P < .001). The median (IQR) postoperative hospital stay was 1 (1-1) day in both groups. The 30-day readmission rate was 3.1% after SG and 4.0% after RYGB (P = .33). There was no 90-day mortality. The 30-day incidence of any adverse event was 40 (4.6%) and 54 (6.3%) in the SG and RYGB groups, respectively (odds ratio, 0.71; 95% CI, 0.47-1.08; P = .11). Corresponding figures for serious adverse events were 15 (1.7%) for the SG group and 23 (2.7%) for the RYGB group (odds ratio, 0.63; 95% CI, 0.33-1.22; P = .19).CONCLUSIONS AND RELEVANCE: This randomized clinical trial of 1735 patients undergoing primary bariatric surgery found that both SG and RYGB were performed with a low perioperative risk without clinically significant differences between groups.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02767505.
