- Background. Sampling of submucosal lesions in the gastrointestinal tract through a flexible endoscope is a well-recognized clinical problem. One technique often used is endoscopic ultrasound-guided fine-needle aspiration, but it does not provide solid tissue biopsies with preserved architecture for histopathological evaluation. To obtain solid tissue biopsies from submucosal lesions, we have constructed a new endoscopic biopsy tool and compared it in a crossover study with the standard double cupped forceps. Methods. Ten patients with endoscopically verified submucosal lesions were sampled. The endoscopist selected the position for the biopsies and used the instrument selected by randomization. After a biopsy was harvested, the endoscopist chose the next site for a biopsy and again used the instrument picked by randomization. A total of 6 biopsies, 3 with the forceps and 3 with the drill instrument, were collected in every patient. Results. The drill instrument resulted in larger total size biopsies (mm2; Mann-Whitney U test, P =.048) and larger submucosal part (%) of the biopsies (Mann-Whitney U test, P =.003) than the forceps. Two patients were observed because of chest pain and suspicion of bleeding in 24 hours. No therapeutic measures were necessary to be taken. Conclusion. The new drill instrument for flexible endoscopy can safely deliver submucosal tissue samples from submucosal lesions in the upper gastrointestinal tract.

- Background: For locally advanced Siewert type II and III tumors we have performed total gastrectomy including resection of the distal 2/3 of the esophagus, through separate abdominal and right chest incisions (THX-ABD). The procedure involves wide lymphadenectomy in the abdomen/chest and a Roux-en-Y jejunostomy to the level of the azygos vein or above. The aim of the study was to investigate short- and long-term results for this rarely used procedure. Methods: Retrospective study of 83 radio-chemotherapy naïve patients with adenocarcinoma at the gastro-esophageal junction (Siewert type II n = 65 and type III n = 18) operated upon 1986–2011. Results: 2/83 (2.4%) patients died in hospital. 70/83 (84%) patients had R0-resections. 82/83 (99%) patients had free longitudinal resection margins. Overall 5-year survival was 22/83 (27%). Conclusion: THX-ABD can be performed with high rates of R0 resections and with low in-hospital mortality. Long-term survival rate was not better compared with less extensive surgical procedures.

- Background: We aimed to evaluate differences in outcome between patients admitted to intensive care unit (ICU) after elective versus acute surgery in a multinational cohort of very old patients (80 years; VIP). Predictors of mortality, with special emphasis on frailty, were assessed.Methods: In total, 5063 VIPs were induded in this analysis, 922 were admitted after elective surgery or intervention, 4141 acutely, with 402 after acute surgery. Differences were calculated using Mann-Whitney-U test and Wilcoxon test. Univariate and multivariable logistic regression were used to assess associations with mortality.Results: Compared patients admitted after acute surgery, patients admitted after elective surgery suffered less often from frailty as defined as CFS (28% vs 46%; p < 0.001), evidenced lower SOFA scores (4 +/- 5 vs 7 +/- 7; p < 0.001). Presence of frailty (CFS >4) was associated with significantly increased mortality both in elective surgery patients (7% vs 12%; p = 0.01), in acute surgery (7% vs 12%; p = 0.02).Conclusions: VIPs admitted to ICU after elective surgery evidenced favorable outcome over patients after acute surgery even after correction for relevant confounders. Frailty might be used to guide clinicians in risk stratification in both patients admitted after elective and acute surgery.
