Esophagectomy is a complex and complication laden procedure. Despite centralization, variations in perioparative strategies reflect a paucity of evidence regarding optimal routines. The use of nasogastric (NG) tubes post esophagectomy is typically associated with significant discomfort for the patients. We hypothesize that immediate postoperative removal of the NG tube is non-inferior to current routines. All Nordic Upper Gastrointestinal Cancer centers were invited to participate in this open-label pragmatic randomized controlled trial (RCT). Inclusion criteria include resection for locally advanced esophageal cancer with gastric tube reconstruction. A pretrial survey was undertaken and was the foundation for a consensus process resulting in the Kinetic trial, an RCT allocating patients to either no use of a NG tube (intervention) or 5 days of postoperative NG tube use (control) with anastomotic leakage as primary endpoint. Secondary endpoints include pulmonary complications, overall complications, length of stay, health related quality of life. A sample size of 450 patients is planned (Kinetic trial: https://www.isrctn.com/ISRCTN39935085). Thirteen Nordic centers with a combined catchment area of 17 million inhabitants have entered the trial and ethical approval was granted in Sweden, Norway, Finland, and Denmark. All centers routinely use NG tube and all but one center use total or hybrid minimally invasive-surgical approach. Inclusion began in January 2022 and the first annual safety board assessment has deemed the trial safe and recommended continuation. We have launched the first adequately powered multi-center pragmatic controlled randomized clinical trial regarding NG tube use after esophagectomy with gastric conduit reconstruction.

Objective: To examine the hypothesis that survival in esophageal cancer increases with more removed lymph nodes during esophagectomy up to a plateau, after which it levels out or even decreases with further lymphadenectomy. Summary of Background Data: There is uncertainty regarding the ideal extent of lymphadenectomy during esophagectomy to optimize long-term survival in esophageal cancer. Methods: This population-based cohort study included almost every patient who underwent esophagectomy for esophageal cancer in Sweden or Finland in 2000-2016 with follow-up through 2019. Degree of lymphadenectomy, divided into deciles, was analyzed in relation to all-cause 5-year mortality. Multivariable Cox regression provided hazard ratios (HR) with 95% confidence intervals (95% CI) adjusted for all established prognostic factors. Results: Among 2,306 patients, the 2nd (4-8 nodes), 7th (21-24 nodes) and 8th decile (25-30 nodes) of lymphadenectomy showed the lowest all-cause 5-year mortality compared to the 1st decile (HR = 0.77, 95% CI 0.61-0.97, HR = 0.76, 95% CI 0.59-0.99, and HR = 0.73, 95% CI 0.57-0.93, respectively). In stratified analyses, the survival benefit was greatest in decile 7 for patients with pathological T-stage T3/T4 (HR = 0.56, 95% CI 0.40-0.78), although it was statistically improved in all deciles except decile 10. For patients without neoadjuvant chemotherapy, survival was greatest in decile 7 (HR = 0.60, 95% CI 0.41-0.86), although survival was also statistically significantly improved in deciles 2, 6, and 8. Conclusion: Survival in esophageal cancer was not improved by extensive lymphadenectomy, but resection of a moderate number (20-30) of nodes was prognostically beneficial for patients with advanced T-stages (T3/T4) and those not receiving neoadjuvant therapy.

The ingestion of button batteries (BB) by children has become more common, and this can cause oesophageal injury, perforation and even life-threatening haemorrhage.A 1-year-old infant who presented to the emergency room with loss of appetite and vomiting, and was discharged with suspected gastro-enteritis is described. One week later she returned with haematemesis. Chest radiography detected a BB in the stomach and it was removed operatively. Haematemesis and hypovolaemic shock ensued and, while waiting for the paediatric cardiothoracic team, the profuse oesophageal bleeding was controlled using an adult-size Sengstaken-Blakemore tube (SBT). An aorto-oesophageal fistula at the aortic arch was identified and repaired. This case highlights the importance of suspecting ingestion of BB, and performing a chest radiography in children who present with swallowing difficulties, haematemesis and haemodynamic instability. The adult-size SBT was well tolerated by the child and was lifesaving in controlling the bleeding from the aorta.AbbreviationAEF: aorto-oesophageal fistula;BB: button battery;CTA: computed tomography angiography;ER: emergency room;GI: gastro-intestinal;SBT: Sengstaken-Blakemore tubeAbbreviationAEF: aorto-oesophageal fistula;BB: button battery;CTA: computed tomography angiography;ER: emergency room;GI: gastro-intestinal;SBT: Sengstaken-Blakemore tubeAbbreviationAEF: aorto-oesophageal fistula;BB: button battery;CTA: computed tomography angiography;ER: emergency room;GI: gastro-intestinal;SBT: Sengstaken-Blakemore tubeAbbreviationAEF: aorto-oesophageal fistula;BB: button battery;CTA: computed tomography angiography;ER: emergency room;GI: gastro-intestinal;SBT: Sengstaken-Blakemore tubeAbbreviationAEF: aorto-oesophageal fistula;BB: button battery;CTA: computed tomography angiography;ER: emergency room;GI: gastro-intestinal;SBT: Sengstaken-Blakemore tubeAbbreviationAEF: aorto-oesophageal fistula;BB: button battery;CTA: computed tomography angiography;ER: emergenc

Background Esophageal perforation is a rare and life-threatening condition with several treatment options. The aim was to assess the incidence, type of treatment and mortality of esophageal perforations in Sweden and to identify risk factors for 90-day mortality. Method All patients admitted with an esophageal perforation from 2007 to 2017 were identified from the National Patient Register. Mortality was assessed by linkage with the Cause of Death Registry. We analyze the incidence and the impact of age, sex, comorbidities on mortality. Results 879 patients with esophageal perforation were identified, giving an incidence rate of 1.09 per 100,000 person-years. The median age at diagnosis was 68.8 years and 60% were men. The mortality was 26% at 90 days. Independent risk factors for death within 90 days were age (odds ratio (OR): 6.20; 95% (confidence interval) CI: 2.16-17.79 at 60-74 years and OR: 11.58; 95% CI: 4.04-33.15 at 75 years or older), peripheral vascular disease (OR: 2.92; 95% CI: 1.44-5.92) and underlying malignant disease (OR: 5.91; 95% CI: 3.86-9.03). In patients younger than 45 years, survival was lower among women than among men (at 5 years 73 and 93%, respectively). The cause of death among young women was often drug-related or suicide. Conclusions 90-day mortality was 26%, old age, vascular disease and underlying malignant disease were risk factors.

The main curative treatment modality for esophageal cancer is resection. Patients initially deemed suitable for resection may become unsuitable, most commonly due to signs of generalized disease or having become unfit for surgery. The aim was to assess risk factors for abandoning esophagectomy and its impact on survival. All patients diagnosed with an esophageal or gastroesophageal junction cancer in the Swedish National Register for Esophageal and Gastric Cancer from 2006-2016 were included and risk factors associated with becoming ineligible for resection were analyzed in multivariable logistic regression analysis. Overall survival was explored by multivariable Cox regression models. Among 1,792 patients planned for resection, 189 (11%) became unsuitable for resection before surgery and 114 (6%) had exploratory surgery without resection. Intermediate and high educational levels were associated with an increased probability of resection (odds ratio (OR) 1.46, 95% CI 1.05-2.05, OR 1.92, 95% CI 1.28-2.87, respectively) as was marital status (married: OR 1.37, 95% CI 1.01-1.85). Clinically advanced disease (cT4: OR 0.38, 95% CI 0.16-0.87; cN3: OR 0.27, 95% CI 0.09-0.81) and neoadjuvant treatment were associated with a decreased probability of resection (OR 0.62, 95% CI 0.46-0.88). Five-year survival for non-resected patients was only 4.5% although neoadjuvant treatment was associated with improved survival (HR 0.75, 95% CI 0.56-0.99). Non-resected patients with squamous cell carcinoma had comparatively reduced survival (HR 1.64, 95% CI 1.10-2.43). High socioeconomic status was associated with an increased probability of completing the plan to resect whereas clinically advanced disease and neoadjuvant treatment were independent factors associated with increased risk of abandoning resectional intent.

BACKGROUND: Minimally invasive oesophagectomy (MIO) is reported to produce fewer respiratory complications than open oesophagectomy. This study assessed differences in postoperative complications between MIO and hybrid MIO (HMIO) employing thoracoscopy and laparotomy, along with the influence of co-morbidities on postoperative outcomes. METHODS: Patients with oesophageal cancer undergoing three-stage MIO or three-stage HMIO between 1999 and 2018 were identified from a prospectively developed database, which included patient demographics, co-morbidities, preoperative therapies, and cancer stage. The primary outcome was postoperative complications in the two groups. Secondary outcomes included duration of operation, blood transfusion requirement, duration of hospital stay, and overall survival. RESULTS: There were 828 patients, of whom 722 had HMIO and 106 MIO, without significant baseline differences. Median duration of operation was longer for MIO (325 versus 289 min; P < 0.001), but with less blood loss (median 250 versus 300 ml; P < 0.001) and a shorter hospital stay (median 12 versus 13 days; P = 0.006). Respiratory complications were not associated with operative approach (31.1 versus 35.2 per cent for MIO and HMIO respectively; P = 0.426). Anastomotic leak rates (10.4 versus 10.2 per cent) and 90-day mortality (1.0 versus 1.7 per cent) did not differ. Cardiac co-morbidity was associated with more medical and surgical complications. Overall survival was associated with AJCC stage and co-morbidities, but not operative approach. CONCLUSION: MIO had a small benefit in terms of blood loss and hospital stay, but not in operating time. Oncological outcomes were similar in the two groups. Postoperative complications were associated with pre-existing cardiorespiratory co-morbidities rather than operative approach.

Background: Microscopically non-radical (R1) oesophageal cancer resection has been associated with worse survival. The aim of this study was to identify risk factors for R1 resection and to investigate how this affects long-term survival. Methods: The Swedish National Register for Oesophageal and Gastric Cancer was used to identify all patients who underwent oesophageal cancer resection with curative intent between 2006 and 2017. Risk factors for R1 resection were assessed by multivariable logistic regression analysis, and factors predicting 5-year survival identified by multivariable Cox regression. Results: The study included 1460 patients. Surgical margins were involved microscopically in 142 patients (9.7 per cent). The circumferential resection margin was involved in 114 (7.8 per cent), the proximal margin in 53 (3.6 per cent), and the distal margin in 29 (2.0 per cent). In 30 specimens (2.1 per cent), two or all three margins were involved. Independent risk factors for R1 resection were male sex, low BMI, absence of neoadjuvant treatments, and clinical T4 disease. The 5-year survival rate for the entire cohort was 42.2 per cent, but only 18.0 per cent for those who had an R1 resection. Independent risk factors for death within 5 years of resection were male sex, age above 60 years, normal BMI, ASA fitness grade III, intermediate-level education, R1 resection (hazard ratio 1.80, 95 per cent c.i. 1.40 to 2.32), clinical T3 disease, and clinical lymph node metastasis. Conclusion: R1 resection is common and predicts poor 5-year survival. Absence of neoadjuvant treatment is a risk factor for R1 resection., Funding Agencies|Swedish Cancer SocietySwedish Cancer Society [180787]

BACKGROUND: Oesophageal cancer management requires extensive in-hospital care. This cohort study aimed to quantify in-hospital care for patients with oesophageal cancer in relation to intended treatment, and to analyse factors associated with risk of spending a large proportion of survival time in hospital. METHODS: All patients with oesophageal cancer in three nationwide registers over a 10-year period were included. In-hospital care during the first year after diagnosis was evaluated, and the proportion of survival time spent in hospital, stratified by intended treatment (curative, palliative or best supportive care), was calculated. Associations between relevant factors and a greater proportion of survival time in hospital were analysed by multivariable logistic regression. RESULTS: In-hospital care was provided for a median of 39, 26, and 15 days in the first year after diagnosis of oesophageal cancer in curative, palliative, and best supportive care groups respectively. Patients receiving curatively intended treatment spent a median of 12 per cent of their survival time in hospital during the first year after diagnosis, whereas those receiving palliative or best supportive care spent 19 and 23 per cent respectively. Factors associated with more in-hospital care included older age, female sex, being unmarried, and chronic obstructive pulmonary disease. CONCLUSION: The burden of in-hospital care during the first year after diagnosis of oesophageal cancer was substantial. Important clinical and socioeconomic factors were identified that predisposed to a greater proportion of survival time spent in hospital., Funding: Erikssons/Bergstroms research fund; Swedish Cancer SocietySwedish Cancer Society [CAN2018/837, CAN2017/1086]; Wallenberg Centres for Molecular Medicine Clinical Facilitation Grant

Introduction Gallbladder cancer is a rare but aggressive malignancy. Surgical resection is recommended for gallbladder polyps >= 10 mm. For gallbladder wall thickening, resection is recommended if malignancy cannot be excluded. The incidence of gallbladder malignancy after cholecystectomy with indications of polyps or wall thickening in the Swedish population is not known. Material/methods A retrospective study was performed at Linkoping University Hospital and included patients who underwent cholecystectomy 2010 - 2018. All cholecystectomies performed due to gallbladder polyps or gallbladder wall thickening without other preoperative malignant signs were identified. Preoperative radiological examinations were re-analysed by a single radiologist. Medical records and histopathology reports were analysed. Results In all, 102 patients were included, of whom 65 were diagnosed with gallbladder polyps and 37 with gallbladder wall thickening. In each group, one patient (1.5% and 2.7% in each group) had gallbladder malignancy >= pT1b.Two (3.1%) and three (8.1%) patients with gallbladder malignancy < T1b were identified in each group. Discussion/conclusion This study indicates that the incidence of malignancy is low without other malignant signs beyond gallbladder polyps and/or gallbladder wall thickening. We propose that these patients should be discussed at a multidisciplinary tumour board. If the polyp is 10-15 mm or if the gallbladder wall is thickened but no other malignant signs are observed, cholecystectomy can be safely performed by an experienced general surgeon at a general surgery unit. If the histopathology indicates >= pT1b, the patient should be referred immediately to a hepatobiliary centre for liver and lymph node resection.

Background Roux-en-Y gastric bypass (RYGB) is the most common bariatric procedure worldwide. Anastomotic stricture is a known complication of RYGB. The aim was to explore the incidence and outcomes of strictures within the Scandinavian Obesity Surgery Registry (SOReg). Method SOReg included prospective data from 36,362 patients undergoing bariatric surgery in the years 2007–2013. Outcomes were recorded at 30-day and at 1-year follow-up according to the standard SOReg routine. The medical charts of patients suffering from stricture after RYGB were requested and assessed. Setting National bariatric surgery registry Results Anastomotic stricture within 1 year of surgery was confirmed in 101 patients representing an incidence of 0.3%. Risk factors for stricture were patient age above 60 years (odds ratio (OR), 6.2 95% confidence interval (CI) 2.7–14.3), circular stapled gastrojejunostomy (OR 2.7, 95% CI 1.4–5.5), postoperative anastomotic leak (OR 8.9 95%, CI 4.7–17.0), and marginal ulcer (OR 30.0, 95% CI 19.2–47.0). Seventy-five percent of the strictures were diagnosed within 70 days of surgery. Two dilatations or less was sufficient to successfully treat 50% of patients. Ten pecent of patients developed perforation during dilatation, and the risk of perforating at each dilatation was 3.8%. Perforation required surgery in six cases but there was no mortality. Strictures in SOReg may be underreported, which could explain the low incidence in the study. Conclusion Most strictures present within 2 months and are successfully treated with two dilatations or less. Dilating a strictured gastrojejunostomy entails a risk of perforation (3.8%).

To compare circular stapler (CS) with linear stapler (LS) in a meta-analysis concerning operative time, anastomotic leaks, wound infections, strictures, and length of stay. Pubmed, Medline, and Scopus were searched for articles published since 2006. Four hundred and five articles were assessed, and 13 articles of which only one was a randomized controlled trial were included in all 49,331 patients from different regions of the world. The pooled analysis shows that operative time was shorter in LS than in CS (weighted mean difference 36.2min; 95% CI 34.7-37.6.; pamp;lt;0.0001). No difference was seen concerning leaks or strictures. The relative risk (RR) of leakage after LS was 80% of the risk after CS; however, the 95% confidence interval (CI) showed overlap (0.58-1.11). The RR of anastomotic stricture after LS was 74% of the risk after CS; however, 95% CI (0.52-1.05) showed overlap. Wound infections were less common after LS than after CS; RR was 27% (95% CI 0.21-0.33). Length of stay (LOS) was 0.65days shorter after LS than after CS (95% CI 0.51-0.78). LS compared with CS results in shorter operative time, less wound infections, and shorter length of stay, but no difference was seen concerning risks of leaks or strictures., Funding Agencies|Svenska Lakaresallskapet [SLS-584761]
