Treatment of anastomotic leakage following Ivor Lewis esophagectomy-10 year experience from a Nordic center.

Anastomotic leakage (AL) is a dreaded complication following esophageal resection. No clear consensus exist for the optimal handling of this severe complication. The aim of this study was to describe the treatment outcome following AL. We conducted a retrospective cross-sectional study including all patients with AL operated with Ivor Lewis esophagectomy from 2010 to 2021 at Oslo University Hospital, Norway. 74/526 (14%) patients had AL. Patient outcomes were analyzed and categorized according to main AL treatment strategy; stent (54%), endoscopic vacuum therapy and stent (EVT + stent) (19%), nasogastric tube and antibiotics (conservative) (16%), EVT (8%) and by other endoscopic means (other) (3%). One patient had surgical debridement of the chest cavity. In 66 patients (89%), the perforation healed after median 27 (range: 4-174) days. Airway fistulation was observed in 11 patients (15%). Leak severity (ECCG) was associated with development of airway fistula (P = 0.03). The median hospital and intensive care unit stays were 30 (range: 12-285) and 9 (range: 0-60) days. The 90-days mortality among patients with AL was 5% and at follow up, 13% of all deaths were related to AL. AL closure rates were comparable across the groups, but longer in the EVT + stent group (55 days vs. 29.5 days, P = 0.04). Thirty-two percent developed a symptomatic anastomotic stricture within 12 months. Conclusion: The majority of AL can be treated endoscopically with preservation of the conduit and the anastomosis. We observed a high number of AL-associated airway fistulas.

Outcome after stent and endoscopic vacuum therapy-based treatment for postemetic esophageal rupture.

OBJECTIVES: Extent of surgical repair of spontaneous esophageal effort rupture (Boerhaave syndrome) has gradually decreased by the emergence of minimal invasive treatment based on endoscopic stent sealing of the perforation. However, for this diagnosis, use of endoscopic vacuum therapy (EVT) is still in its beginning. We present our results after 7-years with both stent and/or EVT-based treatment. MATERIALS AND METHODS: 17 consecutive patients with Boerhaave syndrome from June 2015 to May 2022 were retrospectively registered in a database. The perforation was sealed by stent and/or EVT, and gastric effluent was drained transthoracically by a chest tube or pigtail catheter. Eight out of 14 patients responded to questions on fatigue and dysphagia (Ogilvie's score). RESULTS: Seventeen patients aged median 67 years (range 34-88), had a primary hospital stay of 38 days (7-68). Ninety-day mortality was 6% (n = 1). Perforations were sealed with stent (n = 10), EVT (n = 3) or stent and EVT (n = 4). One patient (6%) needed laparoscopic lavage and transhiatal drainage. Eight patients (47%) were re-stented due to persistent leakage (n = 4) and stent migration (n = 4). Fifteen patients (88%) had complications, including multi-organ failure (n = 9), pleural empyema (n = 8) and esophageal stricture (n = 3). The perforations healed. After 35.5 months (range 2-62) fourteen patients were alive. Eight that responded had no dysphagia and total fatigue score comparable to an age-matched reference population. CONCLUSION: Mortality rate was low after initial stent and EVT-based treatment of Boerhaave syndrome, combined with adequate transthoracic drainage of gastric effluent. Patients required repeated minimal invasive procedures, but with no apparent negative effect on functional outcome.

Targeted genetic and epigenetic profiling of esophageal adenocarcinomas and non-dysplastic Barrett's esophagus.

BACKGROUND: Despite the efforts to describe the molecular landscape of esophageal adenocarcinoma (EAC) and its precursor lesion Barrett's esophagus (BE), discrepant findings are reported. Here, we investigated the prevalence of selected genetic (TP53 mutations and microsatellite instability (MSI) status) and epigenetic (DNA promoter hypermethylation of APC, CDKN2A, MGMT, TIMP3 and MLH1) modifications in a series of 19 non-dysplastic BE and 145 EAC samples. Additional biopsies from adjacent normal tissue were also evaluated. State-of-the-art methodologies and well-defined scoring criteria were applied in all molecular analyses. RESULTS: Overall, we confirmed frequent TP53 mutations among EAC (28%) in contrast to BE, which harbored no mutations. We demonstrated that MSI and MLH1 promoter hypermethylation are rare events, both in EAC and in BE. Our findings further support that APC, CDKN2A, MGMT and TIMP3 promoter hypermethylation is frequently seen in both lesions (21-89%), as well as in a subset of adjacent normal samples (up to 12%). CONCLUSIONS: Our study further enlightens the molecular background of BE and EAC. To the best of our knowledge, this is one of the largest studies addressing a targeted analysis of genetic and epigenetic modifications simultaneously across a combined series of non-dysplastic BE and EAC samples.

Early experience with total robotic D2 gastrectomy in a low incidence region: surgical perspectives.

BACKGROUND: Few European centers have reported on robotic gastrectomy for malignancy. We report our early experience with curative-intent total robotic gastrectomy. MATERIALS AND METHODS: The Intuitive Surgery Da Vinci Surgical System Xi 4 armed robot was used. Routine D2 lymphadenectomy was applied. RESULTS: Some 27 patients with adenocarcinoma (n = 18), hereditary cancer susceptibility (n = 8) and premalignancy (n = 1) were allocated to robotic gastrectomy, three were excluded due to inoperability during surgery. Median (range) age was 66 (18-87) years, 14 (58.3%) were females and body mass index was 25.5 (22.1-33.5) kg/m2. Total gastrectomy was performed in 19 (79.2%) and subtotal in five (20.8%) patients. One (4.2%) procedure was converted to laparotomy. Procedural time was 273 (195-427) minutes. Three (12.5%) patients were reoperated within 30 days, one (4.2%) died. Serious complications (Clavien Dindo IIIb or more) occurred in three (12.5%) patients. Postoperative hospital stay was 10 (6-43) days. Fourteen of 16 (87.5%) patients with adenocarcinoma/premalignancy received radical resections. The median number of harvested lymph nodes was 20 (11-34). Eleven (73.3%) patients with adenocarcinoma had T3/T4 tumors and 6 (40%) had TNM stage III or more. CONCLUSION: Total robotic D2 gastrectomy appears feasible and safe during early introduction in a low incidence region.

Short- and long-term outcomes in patients operated with total minimally invasive esophagectomy for esophageal cancer.

At our hospital, the main treatment for resectable esophageal cancer (EC) has since 2013 been total minimally invasive esophagectomy (TMIE). The aim of this study was to present the short- and long-term results in patients operated with TMIE. This cross-sectional study includes all patients scheduled for TMIE from June 2013 to January 2016 at Oslo University Hospital. Data on morbidity, mortality, and survival were retrospectively collected from the patient administration system and the Norwegian Cause of Death Registry. Long-term postoperative health-related quality of life (HRQL) and level of dysphagia were assessed by patients completing the following questionaries: EORTC QLQ-OG25, QLQ-C30, and the Ogilvie grading scale. A total of 123 patients were included in this study with a median follow-up time of 58 months (1-88 months). 85% had adenocarcinoma, 15% squamous cell carcinoma. Seventeen patients (14%) had T1N0M0, 68 (55%) T2-T3N0M0, or T1-T2N1M0 and 38 (31%) had either T3N1M0 or T4anyNM0. Ninety-eight patients (80%) received neoadjuvant (radio)chemotherapy and 104 (85%) had R0 resection. Anastomotic leak rate and 90-days mortality were 14% and 2%, respectively. The 5-year overall survival was 53%. Patients with tumor free resection margins of >1 mm (R0) had a 5-year survival of 57%. Median 60 months (range 49-80) postoperatively the main symptoms reducing HRQL were anxiety, chough, insomnia, and reflux. Median Ogilvie score was 0 (0-1). In this study, we report relatively low mortality and good overall survival after TMIE for EC. Moreover, key symptoms reducing long-term HRQL were identified.

Short-, long-, and very long-term results of secondary anterior sphincteroplasty in 20 patients with obstetric injury.

PURPOSE: More long-term follow-up studies beyond 10 years after secondary sphincteroplasty for obstetric damage are warranted. This prospective study aimed to compare reported data on incontinence and satisfaction in a cohort of such patients examined at short-, long-, and very long-term follow-up. METHODS: Twenty out of 33 obstetric patients (61%) operated with secondary anterior overlapping sphincteroplasty during February 1996 to April 2004 were evaluated preoperatively and at short-, long-, and very long-term follow-up. Anal incontinence was scored by a combination of Wexner's and St. Mark's incontinence scores. The patients also reported degree of treatment satisfaction. RESULTS: Twenty patients were examined preoperatively and after a median (range) of 5 (2-62), 102 (64-162), and 220 (183-278) months. Corresponding incontinence scores were 11.5 (5-18), 5.5 (1-17) (p < 0.01), 10.0 (0-18) (p > 0.05), and 12.0. (1-18) (p > 0.05). With increasing follow-up times, patients reporting a better outcome were 75%, 65%, and 45%. At very long-term follow-up patients, reports were more dismal than expected in those also reporting improved incontinence cores. Incontinence scores did not improve in patients with neuropathy (n = 5) or patients (n = 5) with more than 10 years of symptoms. CONCLUSION: Initial improvement of anal incontinence attenuated with time, in particular from short- to long-term follow-up. Patients with neuropathy experienced no improvement of incontinence. Beyond stoma formation, in compliant patients, one should consider other treatment options like sacral nerve stimulation and neosphincter formation.

Very long-term outcome after resection rectopexy for internal rectal intussusception.

BACKGROUND: Both at short- and long-term follow-up we have reported major improvement of the symptom of constipation in patients treated with resection rectopexy for internal rectal intussusception (IRI). The aim was to study whether this improvement also persisted in a cohort of these patients after very long-term follow-up. METHODS: Observational and mainly prospective study of a cohort of 13 out of 48 patients with IRI who initially had ligament-preserving resection rectopexy with suture by laparoscopic (n = 11) or open (n = 2) technique. Outcome measures were morbidity, scores for constipation and anal incontinence, patients' report and HRQL. RESULTS: Thirteen out of the 48 initial patients (27%) reported data at very long-term follow-up. Months from preoperatively to short-, long- and very long-term follow-up were median 6, 76 and 159, respectively. Corresponding mean (95% CI) constipation scores were 11.5 (8.3-14.7), 4.2 (1.7-6.6) (p < .001), 5.3 (3.6-7.0) (p < .05) and 13.6 (8.2-19.0). Number of constipated patients were (score ≥ 10) were 8, 1, 0, 1 and 9, respectively. Scores for anal incontinence were 6.1 (2.4-11.4), 5.8 (2.0-9.5), 4.9 (0.9-9.0) and 7.9 (4.3-11.5), respectively. HRQL life was reduced for bodily pain, social functioning, mental health and general health perception. Percentage patients reporting symptomatic improvement were 100, 70 and 53, respectively. CONCLUSIONS: Patients with IRI have a symptomatic relief for more than 6 years after resection rectopexy. The operation did not inflict permanent patient sequela. Motivated patients must be informed about very long-term deterioration of symptomatic relief.

Can medicinal mushrooms have prophylactic or therapeutic effect against COVID-19 and its pneumonic superinfection and complicating inflammation?

Medicinal mushrooms have documented effects against different diseases, including infections and inflammatory disorders. The related Basidiomycota Agaricus blazei Murill (AbM), Hericium erinaceus (HE), and Grifola frondosa (GF) have been shown to exert antimicrobial activity against viral agents, Gram-positive and Gram-negative bacteria, and parasites in vitro and in vivo. Since the mechanism is immunomodulatory and not antibiotical, the mushrooms should be active against multi-drug resistant microbes as well. Moreover, since these Basidiomycota also have anti-inflammatory properties, they may be suited for treatment of the severe lung inflammation that often follows COVID-19 infection. An AbM-based mushroom extract (Andosan™), also containing HE and GF, has been shown to significantly reduce bacteraemia and increase survival in mice with pneumococcal sepsis, and to improve symptoms and quality of life in IBD patients via an anti-inflammatory effect. Hence, such mushroom extracts could have prophylactic or therapeutic effect against the pneumonic superinfection and severe lung inflammation that often complicates COVID-19 infection. Here, we review antimicrobial and anti-inflammatory properties of AbM, HE and GF mushrooms, which could be used for the battle against COVID-19.

Outcome after endoscopic treatment for dysplasia and superficial esophageal cancer - a cohort study.

BACKGROUND: Dysplasia and superficial esophageal cancer should initially be treated endoscopically. Little is known about post-procedural health-related quality of life (HRQL). The aim of this study was to present our results with endoscopic treatment and post-procedural HRQL. MATERIALS AND METHODS: From June 2014 to December 2018, all patients treated with endoscopic mucosal resection (EMR) and/or radiofrequency ablation (RFA) for low-grade dysplasia (LGD), high-grade dysplasia (HGD), T1a and a minority of patients with T1b at Oslo University Hospital were prospectively included. In June 2019, all patients alive were scored according to the Ogilvie dysphagia score as well as the QLQ-C30 and QLQ-OG25 for assessment of HRQL. RESULTS: Eighty-six patients were treated out of whom 22 (26%) had LGD, 44 (51%) HGD, 13 (15%) T1a, and six patients (7%) T1b. Histology revealed adenocarcinoma in 18 (21%) and squamous cell carcinoma in one (1%), respectively. The mean follow-up was 22.9 months. Tumor regression or downstaging was archived in 78% of the patients with LGD, 66% of patients with HGD and in 89% of patients with T1a/b. Five patients (6%) had esophagectomy. There were few and no serious complications. The 90-days mortality was 1%. Fifty-two patients (88%) experienced no dysphagia (Ogilvie score 0). There was no difference in 11 out of the 15 variables in QLQ-C30 when compared to a non-cancerous reference population. CONCLUSIONS: Endoscopic treatment is safe and efficient for treatment of dysplasia and superficial esophageal cancer. The two-years post-procedural level of HRQL and dysphagia was satisfactory.

Nutritional status, sarcopenia, gastrointestinal symptoms and quality of life after gastrectomy for cancer - A cross-sectional pilot study.

BACKGROUND AND AIMS: Gastrointestinal (GI) symptoms, malabsorption, reduced food intake and weight loss are common sequela of gastrectomy. This can result in malnutrition with a subsequent prolonged recovery, reduced physical functioning and deteriorated quality of life (QoL). Few studies have investigated the relationship between GI-symptoms, QoL and malnutrition in long-term survivors of gastric cancer. Therefore, we assess nutritional status, GI-symptoms and QoL 2-5 years after gastrectomy for malignancy. METHODS: A cross-sectional, pilot study was carried out in patients who underwent total or subtotal gastrectomy at Oslo University Hospital between 2012 and 2016, who had not experienced disease recurrence. Subjects above 85 years were excluded. The nutritional status of the patients fell into three groups by a score of subjective global assessment (SGA)-A, B, and C. Muscle mass was measured by body composition by bioelectrical impedance analysis and muscle strength was measured by handgrip strength (HGS). Dietary intake was assessed by repeated 24-h dietary recalls. GI-symptoms and QoL were assessed using GI-Symptom Rating Scale (GSRS) and the SF-36 questionnaire. RESULTS: 21 patients were included. Mean (SD) weight loss was 12.8% (11.6) from preoperative status to follow up. Percentage weight loss was larger after total gastrectomy compared with subtotal gastrectomy (17.9% (12.3) vs. 6.6% (7.1) (p = 0.03)). A low mean intake of energy and protein was reported compared to dietary recommendations for the general Nordic population and intake in a national dietary survey. All of the patients were classified as pre-sarcopenic, and 5% as sarcopenic. Persistent weight loss >10% was observed in 45% of the subjects and these were in risk of malnutrition. Subjects with malnutrition had higher GSRS score for the abdominal pain syndrome (p = 0.042) and lower SF-36 scores for bodily pain (p = 0.01) and vitality (p = 0.02) compared with those without malnutrition. CONCLUSIONS: A high prevalence of weight loss, and pre-sarcopenia was observed. Malnutrition as assessed by SGA was associated with more GI-Symptoms and reduced QoL scores. Further studies with larger number of participants are needed to verify our findings.

Antitumor, Anti-Inflammatory and Antiallergic Effects of Agaricus blazei Mushroom Extract and the Related Medicinal Basidiomycetes Mushrooms, Hericium erinaceus and Grifola frondosa: A Review of Preclinical and Clinical Studies.

Since the 1980s, medicinal effects have been documented in scientific studies with the related Basidiomycota mushrooms Agaricus blazei Murill (AbM), Hericium erinaceus (HE) and Grifola frondosa (GF) from Brazilian and Eastern traditional medicine. Special focus has been on their antitumor effects, but the mushrooms' anti-inflammatory and antiallergic properties have also been investigated. The antitumor mechanisms were either direct tumor attack, e.g., apoptosis and metastatic suppression, or indirect defense, e.g., inhibited tumor neovascularization and T helper cell (Th) 1 immune response. The anti-inflammatory mechanisms were a reduction in proinflammatory cytokines, oxidative stress and changed gut microbiota, and the antiallergic mechanism was amelioration of a skewed Th1/Th2 balance. Since a predominant Th2 milieu is also found in cancer, which quite often is caused by a local chronic inflammation, the three conditions-tumor, inflammation and allergy-seem to be linked. Further mechanisms for HE were increased nerve and beneficial gut microbiota growth, and oxidative stress regulation. The medicinal mushrooms AbM, HE and GF appear to be safe, and can, in fact, increase longevity in animal models, possibly due to reduced tumorigenesis and oxidation. This article reviews preclinical and clinical findings with these mushrooms and the mechanisms behind them.

Gastric adenocarcinoma and proximal polyposis of the stomach ­ a rare form of hereditary gastric cancer. / Gastrisk adenokarsinom og proksimal ventrikkelpolypose ­ en sjelden form for arvelig magesekkreft.

Hereditary ventricular polyposis in the form of gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is a rare condition characterised by a typical distribution of polyps in the stomach and risk of gastric cancer at a young age. Prophylactic gastrectomy may be indicated. The condition is not thought to be associated with increased risk of colon cancer, but the evidence base is limited.

Long-term outcome in patients operated with hybrid esophagectomy for esophageal cancer - a cohort study.

Background: Over the past two decades, hybrid and total minimally invasive esophagectomy for esophageal cancer (EC) has increasingly been implemented with the aim to improve morbidity, functional result and ultimately the prognosis in these patients. However, more results are warranted and in this single-center study we report long-time outcome in a cohort of cancer patients treated with hybrid esophagectomy (HE).Material and methods: Hundred and nine patients with EC operated with HE from November 2007 to June 2013 were included. Clinical, pathological and survival data were retrieved from the patient administration system and the Norwegian Cause of Death Registry. Patients alive were asked to fill out the Ogilvie dysphagia score, EORTC QLQ-C30 and EORTC QLQ-OG25. Survival was analyzed by Kaplan-Meier's method and prognostic factors by uni- and multivariable Cox regression analyses.Results: Median overall follow-up time was 55 months (range 2-135) after R0-2 resection (n = 109) and 76 months (5-135) for R0 resection (n = 100). Five-year overall survival rate was 49% and 53%, respectively. Anastomotic leakage rate and 90-days mortality were 5% and 2%, respectively. Six patients (6%) had later surgery for metastases to mediastinum, hepatoduodenal ligament, brain, lung, liver or bladder median 26 months (4-51) after HE. Forty-one out of 51 patients alive (80%) filled out questionnaires after median 65.5 months (63-123) follow-up. All patients could eat normal food without (n = 37) or with (n = 4) problems. Nearly, half of the patients reported problems with reflux, one-third experienced fatigue and anxiety while one out of four had weight loss and episodes of dyspnea.Conclusions: In this patient series, HE offered low postoperative mortality and good overall long-term survival. Most survivors maintained good quality of life more than five years post treatment. There was a low rate of serious postoperative complications.

NETs analysed by novel calprotectin-based assays in blood donors and patients with multiple myeloma or rheumatoid arthritis: A pilot study.

Two novel enzyme-linked immunosorbent assays (ELISAs), designed to detect complexes containing DNA, leucocyte calprotectin and S100A12 proteins, were generated for improved specificity and rapid measurement of neutrophil extracellular traps (NETs). The assays were applied on plasma and serum samples from blood donors for establishment of reference values, and from patients with multiple myeloma (MM) or rheumatoid arthritis (RA) in order to examine putatively increased values in the two different inflammatory conditions. Although NETs were hardly detectable in healthy individuals, NET levels were as expected highly and statistically significantly increased in RA patients. The detection of statistically significantly increased NET levels in MM is a novel finding.

IgE-sensitization to food and inhalant allergens in IBD patients compared with normal blood donors at Oslo University Hospital, Norway.

Objectives: Crohn's disease (CD) and ulcerative colitis (UC) have been regarded as autoimmune Th-1/Th-17- and Th-2-associated conditions, respectively. The aim of the study was to examine possible differences in allergen sensitization between these diseases and relative to normal blood donors (BD). Materials and methods: Plasma from 29 UC and 37 CD patients with moderate disease activity and 100 healthy age- and gender-matched BD, were analyzed for specific IgE to 22 food- and 28 inhalation allergens using EUROLINE atopy screen. Results: There was significantly higher proportion of allergen sensitized patients in UC compared to BD. Corresponding mean percentages for UC, CD and BD were 8.5, 8.9 (p = .2) and 5.9 (p = .04). There was no intergroup difference in sensitization to food allergens. Most prominent result was the double level of sensitization to inhalants in CD (15%) compared to BD (8%) (p = .03). Overall highest levels of sensitization to inhalants were for grass pollens. Interestingly, the number of allergens (n = 50) the subjects were sensitized to, was significantly lower among UC (n = 20; 40%) (p = .0005) than CD (n = 31; 62%) and BD (n = 38; 76%). Conclusions: The percentage of individuals sensitized to inhalants in CD and to inhalants and foods in UC, were higher than corresponding results in BD. However, whereas allergen positive reactions in CD were comparable to those in BD, they were reduced in UC because of the few UC reactions to food allergens. This contrasts previous data and the study also points to sensitization to inhalants as a potential factor in the complex pathogenesis of IBD.

Outcome after iatrogenic esophageal perforation.

OBJECTIVES: Iatrogenic perforations are the most common cause of esophageal perforation. We present our experience mainly based on a non-operative treatment approach as well as long-term outcome in these patients. MATERIALS AND METHODS: Twenty-one patients were treated for iatrogenic esophageal perforation at Oslo University Hospital, Ullevål from February 2007 to March 2014. The etiology of perforation was dilation of benign stricture in eight patients, either dilation, stenting or stent removal in four with malignant stenosis, during diagnostic endoscopy in four, removal of foreign body in two and by other causes in three patients, respectively. After median 82 months, 10 patients alive (47.6%) were sent questionnaires about dysphagia, HRQoL and fatigue. RESULTS: Median age at time of treatment was 66 years. Median in-hospital stay and mortality were 10.5 days and 4.8%, respectively. Initial treatment in 15 patients (71.4%) was non-surgical of whom one needed delayed debridement for pleural empyema. Initial treatment in six patients (28.6%) was surgical of whom three needed delayed stenting. Altogether 14 patients (66.7%) were stented. Eight (57.1%) had restenting. Median number of stents used was 1 (1-4). The stents were removed after median 36 days. The perforations healed after 2.5 months. After median 82 months, the patients reported reduced HRQoL. There was no significant difference regarding level of dysphagia and fatigue. CONCLUSIONS: We report satisfactorily short-term and long-term results of iatrogenic esophageal perforations. Mortality was low and HRQoL was deteriorated. Dysphagia and fatigue were comparable to a reference population.

Laparascopic resection for gastric cancer at Oslo University Hospital, Ullevål 2015­18. / Laparoskopisk reseksjon av ventrikkelcancer ved Oslo universitetssykehus, Ullevål 2015­18.

BACKGROUND: We wished to assess our experiences with laparoscopy used in curative resection for gastric cancer. MATERIAL AND METHOD: All patients with gastric cancer who underwent curative-intent surgery, irrespective of access, in the period 1 May 2015-28 February 2018 at Oslo University Hospital Ullevål were included. The patient care pathway and oncological results were registered continuously and analysed retrospectively. RESULTS: A total of 93 patients underwent surgery, 48 of whom were women. Median age was 73 (32-89) years, and 16 patients were 80 years of age or above. The duration of the procedure was 265 (125-644) minutes. Altogether seven patients underwent laparotomy, one was planned and six were converted to open surgery. Standardised lymph node dissection was performed in 88 patients. Complications were recorded in 48 patients, of which 11 were serious. A total of six patients had anastomotic leakage. Three died within 30 days/during hospitalisation. Postoperative hospitalisation was 12 (5-78) days. A total of 86 patients underwent radical surgery, five had tumour infiltration in the resection margins, and two had indeterminate resection status. The median number of lymph nodes identified was 18 (0-53). Tumours were locally advanced in 56 patients. INTERPRETATION: Laparoscopic gastric resection with standardised lymph node dissection can be performed in most patients with gastric cancer who undergo curative-intent surgery. The method has become standard in our department.

Outcome after accidental food bolus-induced esophageal perforation.

OBJECTIVES: Food bolus-induced esophageal perforation is much more seldom than iatrogenic and emetic esophageal rupture. We present results from a non-operative treatment approach as well as long-term functional outcome. MATERIALS AND METHODS: Medical records of 10 consecutive patients with food bolus-induced esophageal perforation from October 2007 to May 2015 were retrospectively registered in a database. Six patients developed perforation related to endoscopic removal of impacted food, and four during esophageal passage of bone, meat or bread. Treatment was sealing the perforation by stenting (n = 7) with (n = 4) or without (n = 3) chest tube drainage, chest tube drainage (n = 1), observation (n = 1) and gastroesophageal resection (n = 1) because of concomitant emesis of gastric effluent. After median 51 months nine patients reported about dysphagia, fatigue and health-related quality of life. RESULTS: Ten patients aged median 62.5 years (range 30-85) stayed in our hospital for 12 days (5-68 days). There was no treatment-related mortality. Nine patients were alive 63 months (18-126) after perforation. Five needed restenting (leakage, migration, impacted stent), two had drainage of a mediastinal abscess, one patient developed a transient esophagobronchial fistula. Dysphagia score was 0 (0-1). One patient developed dysphagia for some solid food. Scores for fatigue and HRQoL was similar to a Norwegian reference population. CONCLUSION: Treatment mainly with a non-operative approach occurred without mortality. Complications were handled by restenting and abscess drainage. Functional result for dysphagia was excellent. Interesting results on fatigue and HRQoL must be interpreted with caution because of a limited patient material.

Outcome after stenting and débridement for spontaneous esophageal rupture.

OBJECTIVES: Surgical repair has been the most common treatment of esophageal effort rupture (Boerhaave syndrome). Stent-induced sealing of the perforation has increasingly been used with promising results. We present our eight years´ experience with stent-based and organ-preserving treatment. MATERIALS AND METHODS: Medical records of 15 consecutive patients with Boerhaave syndrome from February 2007 to May 2015 were retrospectively registered in a database. Treatment was sealing of the perforation by stenting, chest tube drainage and débridement of the contaminated thorax. After median 25 months nine out of 10 patients responded to questions on fatigue and Ogilvie's dysphagia score. RESULTS: Fifteen patients, aged median 67.5 years (range 39-88), had a primary hospital stay of 20 days (range 1-80 days). Overall in-hospital mortality was 13%. Observation time was 44 months (range 0-87) and 10 patients were alive of August 2017. Ten patients (67%) needed surgical chest débridement. Five patients (33%) were restented for leakage, migration and for stent removal. Eleven patients (73%) had complications, which included pleural empyema (n = 4), fatal aortic bleeding, lung arterial bleeding, lung embolism, drain-induced lung laceration and respiratory failure. Dysphagia score was low (median 0.5) meaning that they were able to feed themselves. Total fatigue score (mean 14.6) was slightly increased (p = .05) compared with a reference population. CONCLUSIONS: The mortality rate after initial stenting of effort rupture seems to be comparable to standard surgical repair. Most patients required further intervention, either by restenting and/or surgical débridement. The functional result in these patients was satisfactory.

Improved treatment decisions in patients with esophageal cancer.

BACKGROUND: Patients with esophageal cancer seldom achieve long-term survival. This prospective cohort study investigated the selection of patients likely to benefit from curative treatment and whether information on patients' health-related quality of life (HRQL) would assist treatment decisions in the multidisciplinary team. METHODS: Consecutive patients completed HRQL assessments and clinical data were collected before start of treatment. Logistic regression analyses identified clinical factors associated with treatment intent in patients with stage-III disease. Kaplan-Meier method was used for survival analyses and Cox proportional hazards models were used to assess the impact of clinical factors and HRQL on survival in patients planned for curative treatment. RESULTS: Patients with curative treatment intent (n = 90) were younger, had better WHO performance status and less fatigue than patients with palliative treatment intent (n = 89). Median survival for the total cohort (n = 179) and patients with palliative or curative treatment intent was nine, five and 19 months, respectively. In multivariate Cox regression analyses, performance status (0-1 favorable) and comorbidity (ASA I favorable) were factors of importance for survival, whereas measures of HRQL were not. CONCLUSIONS: Patients performance status and comorbidity must be considered in addition to stage of disease to avoid extensive curative treatment in patients with short life expectancy. This study did not provide evidence to support that information on patients HRQL adds value to the multidisciplinary team's treatment decision process.
