RESUMEN
BACKGROUND: With increasing incidence of esophageal cancer, a growing number of patients are at risk of developing delayed gastric conduit emptying (DGCE) in the early postoperative phase after esophagectomy. This condition is of great postoperative concern due to its association with adverse outcomes. PURPOSE: To give a narrative review of the literature concerning radiological diagnosis of DGCE after esophagectomy and a proposal for an improved, functional protocol with objective measurements. MATERIAL AND METHODS: The protocol was designed at Virginia Mason Medical Center in Seattle and is based on the Timed Barium Esophagogram (TBE) concept, which has been adapted to assess the passage of contrast from the gastric conduit into the duodenum. RESULTS: The literature review showed a general lack of standardization and scientific evidence behind the use of radiology to assess DGCE. We found that our proposed standardized upper gastrointestinal (UGI) contrast study considers both the time aspect in DGCE and provides morphologic information of the gastric conduit. This radiological protocol was tested on 112 patients in a trial performed at two high-volume centers for esophageal surgery and included an UGI contrast study 2-3 days postoperatively. The study demonstrated that this UGI contrast study can be included in the standardized clinical pathway after esophagectomy. CONCLUSION: This new, proposed UGI contrast study has the potential to diagnose early postoperative DGCE in a standardized manner and to improve overall patient outcomes after esophagectomy.

Multidisciplinary team meetings (MDTs) are recommended for patients with esophageal cancer. Improved staging, timeliness to surgery and better adherence to guidelines have been attributed to MDTs, but there are few studies published on the MDTs' effect on survival. All patients with esophageal cancer in Sweden between 2006 and 2018 were grouped according to whether they had been discussed at an MDT as part of their clinical pathway. Factors affecting group allocation were explored with multivariable logistic regression, and the impact of MDT on survival was studied with Cox-regression and the Kaplan-Meier estimator. Of 6837 included patients, 1338 patients (20%) were not discussed at an MDT. Advanced age (80-90 years; odds ratio [OR] 0.25, 0.16-0.42 (95% confidence interval)) and clinical stage IVb (OR 0.65, 0.43-0.98) decreased the probability of being presented at an MDT, whereas high education level (OR 1.31, 1.02-1.67), being married (OR 1.20, 1.01-1.43), squamous histology (OR 1.50, 1.22-1.84) and later year of diagnosis (OR 1.33, 1.29-1.37 per year) increased the probability of an MDT. In multivariable adjusted analysis, MDT discussion was associated with improved survival (hazard ratios 0.72, 0.66-0.78) and median survival increased from 4.5 to 10.7 months. MDTs were associated with improved survival for esophageal cancer patients. Elderly patients with advanced disease and poor socioeconomic status were less likely to be presented at an MDT, but had clear survival-benefits if they were discussed in a multidisciplinary setting.
RESUMEN
Aerodigestive fistula (ADF) is defined as a pathological connection between the upper digestive tract and the airway. ADF is associated with high morbidity and mortality and management is often complex. A cohort study including all patients admitted with ADF 2004-2022 at a single tertiary esophageal surgery center was performed based on prospectively collected administrative data and retrospectively collected electronic patient chart data,. Patient demographics, performance status, comorbidity, fistula characteristics, management, and outcomes in terms of morbidity and mortality were assessed in patients with ADF of three distinct types: (i) tumor overgrowth-related, (ii) various benign etiologies, and (iii) post-esophagectomy. Sixty-one patients with ADF were included in the study, 33 (54.1%) tumor overgrowth-related, six (9.8%) benign and 22 (36.1%) post-esophagectomy. In the post-esophagectomy group 15 out of 22 (68.2%) patients were diagnosed with anastomotic leakage prior to ADF diagnosis. Self-expandable metallic stents (SEMS) were used for temporary fistula sealing in 59 out of 61 (96.7%) patients, of which most received stents in both the digestive tract and airway. Temporary fistula sealing with stents was successful enabling discharge from hospital in 47 out of 59 (79.7%) patients. Definitive ADF repair was performed in 16 (26.2%) patients, of which one (6.3%) died within 90-days and 15 could be discharged home with permanently sealed fistulas. ADF is a complex condition associated with high mortality, which often requires multiple advanced interventions. SEMS can be applied in the airway and simultaneously in the digestive tract to temporarily seal the ADF as bridge to definitive surgical repair.

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.

In September 2022, the Public Health Agency of Sweden observed an increase in domestic Salmonella Typhimurium cases through the Swedish electronic notification system, and an outbreak strain was identified with whole genome sequencing. Overall, 109 cases with symptom onset between 17 September and 24 November 2022 were reported from 20 of 21 Swedish regions. The median age of cases was 52â¯years (range 4-87â¯years) and 62% were female. A case-control study found cases to be associated with consumption of rocket salad (adjusted odds ratio (aOR)â¯=â¯4.9; 95% confidence interval (CI): 2.4-10, p value < 0.001) and bagged mixed salad (aORâ¯=â¯4.0; 95% CI: 1.9-8.1, p value < 0.001). Trace-back, supported by Finnish authorities who identified the Swedish outbreak strain in a Finnish cluster during the same time period, identified rocket salad, cultivated, pre-washed and pre-packed in Sweden as the likely source of the outbreak. No microbiological analyses of rocket salad were performed. Our investigation indicates that bagged leafy greens such as rocket salad, regardless of pre-washing procedures in the production chain, may contain Salmonella and cause outbreaks, posing a health risk to consumers. We emphasise the need for primary producers of leafy greens to identify possible contamination points to prevent outbreaks.

PURPOSE: To assess whether androgens play a role in explaining the sex related differences in the incidence of colorectal cancer (CRC). METHODS: A nationwide matched cohort study was conducted employing the Prostate Cancer data Base Sweden (PCBaSe) 4.0 during the study period 2006-2016. Prostate cancer (PC) patients receiving androgen deprivation therapy (ADT) were treated as exposed. Prostate cancer-free men from the general population were randomly selected and matched to the index case by birth year and county of residence, forming the unexposed group. All were followed until a diagnosis of CRC, death, emigration, or end of the study period. The risk of CRC among ADT exposed PC patients compared to unexposed cancer-free men was calculated using a flexible parametric survival model and expressed as hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS: There was an increased risk of CRC among ADT exposed PC patients compared to unexposed cancer-free men (HR 1.27 [95% CI 1.15-1.41]), in particular an increased risk of adenocarcinoma of the colon (HR 1.33 [95% CI 1.17-1.51]) and more specifically an increased risk of adenocarcinoma of the distal colon (HR 1.53 [95% CI 1.26-1.85]). Examination of latency effects yielded significantly decreased HRs over time for CRC (p = 0.049 for trend). CONCLUSIONS: This population-based study found an increased risk of CRC among PC patients exposed to ADT, specifically adenocarcinoma of the distal colon, which indicates an increased association between ADT (PC + ADT) and CRC but not a positive dose-response trend questioning a true causal effect.

BACKGROUND: Adjuvant postoperative treatment with aspirin and statins may improve survival in several solid tumors. This study aimed to assess whether these medications improve the survival after curatively intended treatment (including esophagectomy) for esophageal cancer in an unselected setting. METHODS: This nationwide cohort study included nearly all patients who underwent esophagectomy for esophageal cancer in Sweden from 2006 to 2015, with complete follow-up throughout 2019. Risk of 5-year disease-specific mortality in users compared to non-users of aspirin and statins was analyzed using Cox regression, providing hazard ratios (HR) with 95% confidence intervals (CI). The HRs were adjusted for age, sex, education, calendar year, comorbidity, aspirin/statin use (mutual adjustment), tumor histology, pathological tumor stage, and neoadjuvant chemo(radio)therapy. RESULTS: The cohort included 838 patients who survived at least 1 year after esophagectomy for esophageal cancer. Of these, 165 (19.7%) used aspirin and 187 (22.3%) used statins during the first postoperative year. Neither aspirin use (HR 0.92, 95% CI 0.67-1.28) nor statin use (HR 0.88, 95% CI 0.64-1.23) were associated with any statistically significant decreased 5-year disease-specific mortality. Analyses stratified by subgroups of age, sex, tumor stage, and tumor histology did not reveal any associations between aspirin or statin use and 5-year disease-specific mortality. Three years of preoperative use of aspirin (HR 1.26, 95% CI 0.98-1.65) or statins (HR 0.99, 95% CI 0.67-1.45) did not decrease the 5-year disease-specific mortality. CONCLUSIONS: Use of aspirin or statins might not improve the 5-year survival in surgically treated esophageal cancer patients.

INTRODUCTION: Use of antipsychotic drugs, especially second-generation agents, has been suggested to cause acute pancreatitis in multiple case reports; however, such an association has not been corroborated by larger studies. This study examined the association of antipsychotic drugs with risk of acute pancreatitis. METHODS: Nationwide case-control study, based on data from several Swedish registers and including all 52,006 cases of acute pancreatitis diagnosed in Sweden between 2006 and 2019 (with up to 10 controls per case; n = 518,081). Conditional logistic regression models were used to calculate odds ratios (ORs) in current and past users of first-generation and second-generation antipsychotic drugs (dispensed prescription <91 and ≥91 days of the index date, respectively) compared with never users of such drugs. RESULTS: In the crude model, first-generation and second-generation antipsychotic drugs were associated with increased risk of acute pancreatitis, with slightly higher ORs for past use (1.58 [95% confidence interval 1.48-1.69] and 1.39 [1.29-1.49], respectively) than for current use (1.34 [1.21-1.48] and 1.24 [1.15-1.34], respectively). The ORs were largely attenuated in the multivariable model-which included, among others, alcohol abuse and the Charlson comorbidity index-up to the point where only a statistically significant association remained for past use of first-generation agents (OR 1.18 [1.10-1.26]). CONCLUSION: There was no clear association between use of antipsychotic drugs and risk of acute pancreatitis in this very large case-control study, indicating that previous case report data are most likely explained by confounding.

BACKGROUND: Adequate lymphadenectomy is an important step in gastrectomy for cancer, with a modified D2 lymphadenectomy being recommended for advanced gastric cancers. When assessing a novel technique for the treatment of gastric cancer, lymphadenectomy should be non-inferior. The aim of this study was to assess completeness of lymphadenectomy and distribution patterns between open total gastrectomy (OTG) and minimally invasive total gastrectomy (MITG) in the era of peri-operative chemotherapy. METHODS: This is a retrospective analysis of the STOMACH trial, a randomized clinical trial in thirteen hospitals in Europe. Patients were randomized between OTG and MITG for advanced gastric cancer after neoadjuvant chemotherapy. Three-year survival, number of resected lymph nodes, completeness of lymphadenectomy, and distribution patterns were examined. RESULTS: A total of 96 patients were included in this trial and randomized between OTG (49 patients) and MITG (47 patients). No difference in 3-year survival was observed, this was 57.1% in OTG group versus 46.8% in MITG group (P = 0.186). The mean number of examined lymph nodes per patient was 44.3 ± 16.7 in the OTG group and 40.7 ± 16.3 in the MITG group (P = 0.209). D2 lymphadenectomy of 71.4% in the OTG group and 74.5% in the MITG group was performed according to the surgeons; according to the pathologist compliance to D2 lymphadenectomy was 30% in the OTG group and 36% in the MITG group. Tier 2 lymph node metastases (stations 7-12) were observed in 19.6% in the OTG group versus 43.5% in the MITG group (P = 0.024). CONCLUSION: No difference in 3-year survival was observed between open and minimally invasive gastrectomy. No differences were observed for lymph node yield and type of lymphadenectomy. Adherence to D2 lymphadenectomy reported by the pathologist was markedly low.

PURPOSE: To determine the relationship between postoperative C-reactive protein (CRP) as an early indicator of anastomotic leakage (AL) after esophagectomy for esophageal cancer. METHODS: We reviewed patients diagnosed with esophageal or esophagogastric junctional cancer who underwent esophagectomy between 2006 and 2022 at the Karolinska University Hospital, Stockholm, Sweden. Multivariable logistic regression models estimated relative risk for AL by calculating the odds ratio (OR) with a 95% confidence interval (CI). The cut-off values for CRP were based on the maximum Youden's index using receiver operating characteristic curve analysis. RESULTS: In total, 612 patients were included, with 464 (75.8%) in the non-AL (N-AL) group and 148 (24.2%) in the AL group. Preoperative body mass index and the proportion of patients with the American Society of Anesthesiologists physical status classification 3 were significantly higher in the AL group than in the N-AL group. The median day of AL occurrence was the postoperative day (POD) 8. Trends in CRP levels from POD 2 to 3 and POD 3 to 4 were significantly higher in the AL than in the N-AL group. An increase in CRP of ≥ 4.65% on POD 2 to 3 was an independent risk factor for AL with the highest OR of 3.67 (95% CI 1.66-8.38, p = 0.001) in patients with CRP levels on POD 2 above 211 mg/L. CONCLUSION: Early changes in postoperative CRP levels may help to detect AL early following esophageal cancer surgery.

OBJECTIVE: To examine 5-year survival in esophageal cancer after MIE compared to OE. SUMMARY BACKGROUND DATA: MIE is becoming an increasingly common approach in the surgical treatment of esophageal cancer. A recent meta-analysis suggested 18% lower 5-year all-cause mortality after MIE compared to OE, but the quality of the included studies was limited. METHODS: Population-based cohort study including almost all patients who underwent elective esophagectomy for esophageal cancer in Sweden or Finland in 2010 to 2016, with follow-up until end of 2019. Cox regression was used to provide hazard ratios (HRs) with 95% confidence intervals (CIs) of all-cause 5-year mortality (main outcome) after MIE (hybrid or total) versus OE. Adjustments were made for age, sex, comorbidity, pathological tumor stage, histological tumor type, neoadjuvant chemo(radio)therapy, country, and annual hospital volume of esophagectomy. RESULTS: Among all 1264 patients, 470 (37.2%) underwent MIE and 794 (62.8%) underwent OE. MIE was associated with an 18% decreased risk of all-cause 5-year mortality, compared to OE [adjusted HR 0.82, 95% CI 0.67- 1.00 ( P = 0.048)]. The HR of all-cause 5-year mortality was seemingly lower after total MIE compared to OE (adjusted HR 0.77, 95% CI 0.60-0.98) than after hybrid MIE compared to OE (adjusted HR 0.87, 95% CI 0.68-1.11). CONCLUSIONS: This bi-national study indicates that MIE is associated with a higher 5-year survival than OE in patients with esophageal cancer, and that the survival benefit is greater after total MIE than hybrid MIE.

BACKGROUND: Recent research indicates long-term survival benefits of minimally invasive esophagectomy (MIE) compared with open esophagectomy (OE) for patients with esophageal and gastroesophageal junction (GEJ) cancers, but there is a need for more population-based studies. METHODS: We conducted a prospective population-based nationwide cohort study including all patients in Sweden diagnosed with esophageal or junctional cancer who underwent a transthoracic esophagectomy with intrathoracic anastomosis. Data were collected from the Swedish National Register for Esophageal and Gastric Cancer in 2006-2019. Patients were grouped into OE and MIE including hybrid MIE (HMIE) and totally MIE (TMIE). Overall survival and short-term postoperative outcomes were compared using Cox regression and logistic regression models, respectively. All models were adjusted for age, sex, American Society of Anesthesiologists (ASA) score, clinical T and N stage, neoadjuvant therapy, year of surgery, and hospital volume. RESULTS: Among 1404 patients, 998 (71.1%) underwent OE and 406 (28.9%) underwent MIE. Compared with OE, overall survival was better following MIE (hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.55-0.94), TMIE (HR 0.67, 95% CI 0.47-0.94), and possibly also after HMIE (HR 0.76, 95% CI 0.56-1.02). MIE was associated with shorter operation time, less intraoperative bleeding, higher number of resected lymph nodes, and shorter hospital stay compared with OE. MIE was also associated with fewer overall complications (odds ratio [OR] 0.70, 95% CI 0.47-1.03) as well as non-surgical complications (OR 0.64, 95% CI 0.40-1.00). CONCLUSIONS: MIE seems to offer better survival and similar or improved short-term postoperative outcomes in esophageal and GEJ cancers compared with OE in this unselected population-based cohort.

In autumn 2019, the Public Health Agency of Sweden identified a cluster of Salmonella Newport cases by whole genome sequencing (WGS). Cases' distribution in place and time indicated a nation-wide ongoing outbreak. An investigation was initiated to identify the source and prevent further cases. We conducted a case-case study based on notified salmonellosis cases and a Salmonella trawling questionnaire, comparing 20 outbreak cases and 139 control cases. Food exposures were compared by adjusted odds ratios (aOR) with 95% confidence interval (CI) using logistic regression. Implicated foods were sampled. Outbreak cases were more likely to have consumed crayfish (aOR = 26; 95% CI: 6.3-105). One specific brand of imported frozen, pre-cooked whole crayfish in dill brine was identified as the source. Salmonella Newport was later detected in different batches from retail and in one sample from border control. Isolates from food samples clustered with the human outbreak strain by WGS. Although the retailer made a complete recall, two more cases were identified long afterwards. This investigation demonstrated the successful use of a case-case study and targeted microbiological testing to identify the source. The immediate action taken by the retailer was important to confirm the source and stop the outbreak.

BACKGROUND: Population-based patient reported outcome data in oesophageal cancer are rare. The main purpose of this study was to describe health-related quality of life (HRQOL) 1 year after the diagnosis of oesophageal cancer, comparing subgroups of curatively and palliatively managed patients. METHODS: This is a nationwide population-based cohort study, based on the Swedish National Registry for Oesophageal and Gastric Cancer (NREV) with prospectively registered data, including HRQOL instruments from the European Organisation for Research and Treatment of Cancer including the core and disease specific questionnaires (EORTC QLQ-C30 and QLQ-OG25). Patients diagnosed with oesophageal cancer between 2009 and 2016 and with complete HRQOL data at 1 year follow-up were included. HRQOL of included patients was compared to a reference population matched by age and gender to to a previous cohort of unselected Swedish oesophageal cancer patients. Linear regression was performed to calculate mean scores with 95% confidence intervals (CI) and adjusted linear regression analysis was used to calculate mean score differences (MD) with 95% CI. RESULTS: A total of 1156 patients were included. Functions and global health/quality of life were lower in both the curative and palliative cohorts compared to the reference population. Both curatively and palliatively managed patients reported a severe symptom burden compared to the reference population. Patients who underwent surgery reported more problems with diarrhoea compared to those treated with definitive chemoradiotherapy (dCRT) (MD -14; 95% CI - 20 to - 8). Dysphagia was more common in patiens treated with dCRT compared to surgically treated patients (MD 11; 95% CI 4 to 18). Those with palliative intent due to advanced tumour stage reported more problems with dysphagia compared to those with palliative intent due to frailty (MD -18; 95% CI - 33 to - 3). CONCLUSIONS: One year after diagnosis both curative and palliative intent patients reported low function scores and severe symptoms. Dysphagia, choking, and other eating related problems were more pronounced in palliatively managed patients and in the curative intent patients treated with dCRT.

BACKGROUND: Surgical resection with adequate lymphadenectomy is regarded the only curative option for gastric cancer. Regarding minimally invasive techniques, mainly Asian studies showed comparable oncological and short-term postoperative outcomes. The incidence of gastric cancer is lower in the Western population and patients often present with more advanced stages of disease. Therefore, the reproducibility of these Asian results in the Western population remains to be investigated. METHODS: A randomized trial was performed in thirteen hospitals in Europe. Patients with an indication for total gastrectomy who received neoadjuvant chemotherapy were eligible for inclusion and randomized between open total gastrectomy (OTG) or minimally invasive total gastrectomy (MITG). Primary outcome was oncological safety, measured as the number of resected lymph nodes and radicality. Secondary outcomes were postoperative complications, recovery and 1-year survival. RESULTS: Between January 2015 and June 2018, 96 patients were included in this trial. Forty-nine patients were randomized to OTG and 47 to MITG. The mean number of resected lymph nodes was 43.4 ± 17.3 in OTG and 41.7 ± 16.1 in MITG (p = 0.612). Forty-eight patients in the OTG group had a R0 resection and 44 patients in the MITG group (p = 0.617). One-year survival was 90.4% in OTG and 85.5% in MITG (p = 0.701). No significant differences were found regarding postoperative complications and recovery. CONCLUSION: These findings provide evidence that MITG after neoadjuvant therapy is not inferior regarding oncological quality of resection in comparison to OTG in Western patients with resectable gastric cancer. In addition, no differences in postoperative complications and recovery were seen.

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.

Anastomotic leak is a serious complication after esophagectomy. Endoscopic vacuum therapy (EVT) has become increasingly popular in treating upper gastrointestinal anastomotic leaks over the last years. We are here reporting our current complete experience with EVT as primary treatment for anastomotic leak following esophagectomy. This is a retrospective study analyzing all patients with EVT as primary treatment for anastomotic leak after esophagectomy between November 2016 and January 2020 at Karolinska University Hospital, Sweden. The primary endpoint was anastomotic fistula healing with EVT only. Twenty-three patients primarily treated with EVT after anastomotic leak following esophagectomy were included. Median duration of EVT was 17 days (range 5-56) with a median number of 3 (range 1-14) vacuum sponge changes per patient. A total number of 95 vacuum sponges were placed in the entire cohort, of which 93 (97.9%) were placed intraluminally and 2 (2.1%) extraluminally. The median changing time interval of sponges was 5 days (range 2-8). Successful fistula healing was achieved in 19 of 23 patients (82.6%), of which 17 (73.9%) fistulas healed with EVT only. There were 2 (8.7%) airway fistulas following EVT. No other adverse events occurred. Three patients (13%) died in-hospital. In conclusion EVT seems to be a safe and feasible therapy option for anastomotic leak following esophagectomy. The effect of EVT on the risk for development of airway fistulas needs to be addressed in future studies and until more data are available care should be taken regarding sponge positioning as well as extended treatment duration.

OBJECTIVE: To investigate if prolonged TTS after completed nCRT improves postoperative outcomes for esophageal and esophagogastric junction cancer. SUMMARY OF BACKGROUND DATA: TTS has traditionally been 4-6 weeks after completed nCRT. However, the optimal timing is not known. METHODS: A multicenter clinical trial was performed with randomized allocation of TTS of 4-6 or 10-12 weeks. The primary endpoint of this sub-study was overall postoperative complications defined as Clavien-Dindo grade II-V. Secondary endpoints included complication severity according to Clavien-Dindo grade IIIb-V, postoperative 90-day mortality, and length of hospital stay. The study was registered in Clinicaltrials.gov (NCT02415101). RESULTS: In total 249 patients were randomized. There were no significant differences between standard TTS and prolonged TTS with regard to overall incidence of complications Clavien-Dindo grade II-V (63.2% vs 72.6%, P = 0.134) or regarding Clavien-Dindo grade IIIb-V complications (31.6% vs 34.9%, P = 0.603). There were no statistically significant differences between standard and prolonged TTS regarding anastomotic leak (P = 0.596), conduit necrosis (P = 0.524), chyle leak (P = 0.427), pneumonia (P = 0.548), and respiratory failure (P = 0.723). In the standard TTS arm 5 patients (4.3%) died within 90 days of surgery, compared to 4 patients (3.8%) in the prolonged TTS arm (P = 1.0). Median length of hospital stay was 15 days in the standard TTS arm and 17 days in the prolonged TTS arm (P = 0.234). CONCLUSION: The timing of surgery after completed nCRT for carcinoma of the esophagus or esophagogastric junction, is not of major importance with regard to short-term postoperative outcomes.

BACKGROUND: Laparoscopic gastrectomy (LG) for cancer has been introduced in institutions worldwide in an effort to minimize surgical trauma, while aiming to provide comparable oncological outcomes to conventional open gastrectomy (OG). The aim of this study was to present our results during the period of implementation of the laparoscopic technique. MATERIALS AND METHODS: In 2012, LG for the treatment of gastric cancer was introduced at our institution. The results presented are based on a retrospective analysis of data from a cohort of all patients treated with curative intent over the period 2010-2018. RESULTS: During the study period, 206 patients underwent surgery for gastric cancer: 129 patients (62.6%) had an OG and 77 patients (37.4%) an LG. The conversion rate due to technical reasons was 2.6%. LG was associated with significantly less intraoperative blood loss [mean (mL), OG 544 versus LG 176] and shorter hospital stay than OG [mean (d), OG 12 versus LG 8], fewer severe complications (Clavien-Dindo grade ≥ IIIb) [OG 29 (22.5%) versus LG 9 (11.7%), P = 0.081], significantly lower anastomotic leak rate [OG 18 (14.0%) versus LG 1 (1.3%)] and no 90-day mortality. The percentage of R0 resections was similar between the two groups (OG 82.2% versus LG 85.7%, P = 0.507), while the mean number of resected lymph nodes was significantly higher in the laparoscopic group [OG 34 versus LG 39, P = 0.030]. CONCLUSIONS: Our data suggest that similar and, in some aspects, better short-term outcomes can be achieved with LG with maintained oncological quality.

A stenosing tumour in the throat region is a common indication for percutaneous endoscopic gastrostomy (PEG), which may be used for enteral nutrition in palliative cases or placed prior to curative treatment (surgery, radiotherapy and/or chemotherapy) and removed when the patient has recovered and has a reliable and adequate oral intake. Major complications related to PEG are rare, but their treatment poses a challenge. We are presenting a case of the transmission of metastasis to the gastrostomy site in a patient with pharynx cancer after percutaneous endoscopic gastrostomy.
