Many health-promoting effects have been attributed to the intake of probiotic cells. However, it is important that probiotic cells arrive at the site of their activity in a viable state in order to exert their beneficial effects. Careful selection of the appropriate probiotic formulation is therefore required as mainly the type of probiotic species/strain and the administration strategy may affect survival of the probiotic cells during the upper gastrointestinal (GIT) passage. Therefore, the current study implemented Simulator of the Human Microbial Ecosystem (SHIME®) technology to investigate the efficacy of different commercially available probiotic formulations on the survival and culturability of probiotic bacteria during upper GIT passage. Moreover, Colon-on-a-Plate (CoaP™) technology was applied to assess the effect of the surviving probiotic bacteria on the gut microbial community (activity and composition) of three human donors. Significantly greater survival and culturability rates were reported for the delayed-release capsule formulation (>50%) as compared to the powder, liquid, and standard capsule formulations (<1%) (p < 0.05), indicating that the delayed-release capsule was most efficacious in delivering live bacteria cells. Indeed, administration of the delayed-release capsule probiotic digest resulted in enhanced production of SCFAs and shifted gut microbial community composition towards beneficial bacterial species. These results thus indicate that careful selection of the appropriate probiotic formulation and administration strategy is crucial to deliver probiotic cells in a viable state at the site of their activity (distal ileum and colon).

Upper gastrointestinal bleeding (UGIB) is a major cause of morbidity and mortality. Clinical symptoms that patients may present with include: hematemesis, coffee-ground emesis, melena, and hematochezia. Clinical signs can range from tachycardia to shock. The anatomical landmark that differentiates upper gastrointestinal (GI) bleeds from lower bleeds is the ligament of Treitz. The first steps of treating a patient who presents with signs of UGIB are resuscitation with appropriate fluids and blood products as necessary. The consideration of endoscopy and the urgency at which it should be performed is also vital during initial resuscitation. Endoscopic therapy should ideally be performed within 24 hours of presentation after initial stabilization with crystalloids and blood products. Intravenous proton pump inhibitors are the mainstay in the initial management of upper GI bleeding from a non-variceal etiology, and they should be administered in the acute setting to decrease the probability of high-risk stigmata seen during endoscopy. Pro-kinetic agents can be given 30 minutes to an hour before endoscopy and may aid in the diagnosis of UGIB. There are 3 broad categories of endoscopic management for UGIB: injection, thermal, and mechanical. Each endoscopic method can be used alone or in combination with others; however, the injection technique with epinephrine should always be used in conjunction with another method to increase the success of achieving hemostasis. In this review article, we will review the steps of triage and initial resuscitation in UGIB, causes of UGIB and their respective management, several endoscopic techniques and their effectiveness, and prognosis with a primary focus limited to non-variceal bleeding.

BACKGROUND: Gastroesophageal cancer patients\' information needs remain understudied, despite their complex treatment trajectories.
METHODS: This study examined the (i) information needs of patients with or without postoperative complications, (ii) information needs of male and female patients, and (iii) the association between information needs and health-related quality of life (HR-QoL) following gastroesophageal cancer surgery. Patients completed the EORTC-QLQ-INFO25, QLQ-C30, and QLQ-OG25 questionnaires before and after curative surgery. Five information needs domains were investigated: information about the disease, about treatments, about medical tests, about things patients can do to help themselves, and overall helpfulness. Additionally, HR-QoL domains global health status, eating restrictions, and anxiety were explored.
RESULTS: A total of 132 patients completed the questionnaires at baseline, 216 patients at 6-12 months, 184 patients at 18-24 months, and 163 patients at 3-5 years post-operation. There were no significant differences in information needs between patients with or without complications or between male and female patients. Patients with a higher global health status found the information more helpful at 6-12 months (p < 0.001), 18-24 months (p < 0.001), and 3-5 years (p < 0.001) postoperatively, as did patients who experienced more anxiety at 18-24 months (p = 0.009) and 3-5 years (p < 0.001).
CONCLUSIONS: Gastroesophageal cancer patients, regardless of sex or postoperative complications, have consistent information needs, yet those with higher global health status and elevated anxiety levels find the information particularly helpful, emphasizing the importance of tailored communication strategies.

Background and Objectives: Anastomotic insufficiencies (AI) and perforations of the upper gastrointestinal tract (uGIT) result in high morbidity and mortality. Endoscopic stent placement and endoluminal vacuum therapy (EVT) have been established as surgical revision treatment options. The Eso-Sponge® is the only licensed EVT system with limitations in treating small defects (<10 mm). Therefore, a fistula sponge (FS) was developed for the treatment of such defects as a new therapeutic approach. The aim of this study was to evaluate both EVT options\' indications, success rates, and complications in a retrospective, comparative approach. Materials and Methods: Between 01/2018 and 01/2021, the clinical data of patients undergoing FS-EVT or conventional EVT (cEVT; Eso-Sponge®, Braun Melsungen, Melsungen, Germany) due to AI/perforation of the uGIT were recorded. Indication, diameter of leakage, therapeutic success, and complications during the procedure were assessed. FSs were prepared using a nasogastric tube and a porous drainage film (Suprasorb® CNP, Lohmann & Rauscher, Rengsdorf, Germany) sutured to the distal tip. Results: A total of 72 patients were included (20 FS-EVT; 52 cEVT). FS-EVT was performed in 60% suffering from AI (cEVT = 68%) and 40% from perforation (cEVT = 32%; p > 0.05). FS-EVT\'s duration was significantly shorter than cEVT (7.6 ± 12.0 d vs. 15.1 ± 14.3 d; p = 0.014). The mean diameter of the defect was 9 mm in the FS-EVT group compared to 24 mm in cEVT (p < 0.001). Therapeutic success was achieved in 90% (FS-EVT) and 91% (cEVT; p > 0.05). Conclusions: EVT comprises an efficient treatment option for transmural defects of the uGIT. In daily clinical practice, fistulas < 10 mm with large abscess formations poses a special challenge since intraluminal cEVT usually is ineffective. In these cases, the concept of extraluminal FS placement is safe and effective.

Sarcoidosis is a disease of unknown etiology, characterized by noncaseating granulomas. Generally, the condition primarily manifests in the lungs. Extrapulmonary involvement is common, but localization in the gastrointestinal system is rare. Here, we present the case of a 37-year-old male who became increasingly hemodynamically unstable during the diagnostic workup for sarcoidosis due to acute variceal bleeding. The underlying mechanism was later attributed to portal hypertension caused by hepatic involvement of the disease. This case demonstrates the importance of considering variceal hemorrhage as a rare but life-threatening complication of gastrointestinal localization of sarcoidosis.

UNASSIGNED: Upper gastrointestinal obstruction is an extremely rare complication of primary ovarian cancer. We present a case of primary advanced ovarian cancer with gastroduodenal obstruction successfully managed with neoadjuvant chemotherapy (NAC) and conservative treatment.
UNASSIGNED: A 60-year-old woman was referred to our hospital for advanced ovarian cancer with upper gastrointestinal obstruction. Computed tomography and endoscopy revealed severe duodenal obstruction caused by dissemination. NAC was initiated with conservative management using a nasogastric tube and total parenteral nutrition (TPN). She was able to eat and TPN was stopped after three months. Complete resection was achieved with interval debulking surgery (IDS) not involving pancreatoduodenectomy, which would have been necessary for primary debulking surgery. There were no serious postoperative complications.
UNASSIGNED: NAC with conservative management can improve upper gastrointestinal obstruction in patients with primary advanced ovarian cancer. Furthermore, IDS is expected to allow complete resection, avoiding highly invasive surgeries.

BACKGROUND: Magnetically assisted capsule endoscopy (MACE) showed the feasibility for upper gastrointestinal examination. To further enhance the performance of conventional MACE, it is necessary to provide quality-improved and three-dimensional images. The aim of this clinical study was to determine the efficacy and safety of novel three-dimensional MACE (3D MACE) for upper gastrointestinal and small bowel examination at once.
METHODS: This was a prospective, single-center, non-randomized, and sequential examination study (KCT0007114) at Dongguk University Ilsan Hospital. Adult patients who visited for upper endoscopy were included. The study protocol was conducted in two stages. First, upper gastrointestinal examination was performed using 3D MACE, and a continuous small bowel examination was performed by conventional method of capsule endoscopy. Two hours later, an upper endoscopy was performed for comparison with 3D MACE examination. The primary outcome was confirmation of major gastric structures (esophagogastric junction, cardia/fundus, body, angle, antrum, and pylorus). Secondary outcomes were confirmation of esophagus and duodenal bulb, accuracy for gastric lesions, completion of small bowel examination, 3D image reconstruction of gastric lesion, and safety.
RESULTS: Fifty-five patients were finally enrolled. The examination time of 3D MACE was 14.84 ± 3.02 minutes and upper endoscopy was 5.22 ± 2.39 minutes. The confirmation rate of the six major gastric structures was 98.6% in 3D MACE and 100% in upper endoscopy. Gastric lesions were identified in 43 patients during 3D MACE, and 40 patients during upper endoscopy (Sensitivity 0.97). 3D reconstructed images were acquired for all lesions inspected by 3D MACE. The continuous small bowel examination by 3D MACE was completed in 94.5%. 3D MACE showed better overall satisfaction (3D MACE 9.55 ± 0.79 and upper endoscopy 7.75 ± 2.34, p<0.0001). There were no aspiration or significant adverse event or capsule retention in the 3D MACE examination.
CONCLUSIONS: Novel 3D MACE system is more advanced diagnostic modality than the conventional MACE. And it is possible to perform serial upper gastrointestinal and small bowel examination as a non-invasive and one-step test. It would be also served as a bridge to pan-endoscopy.

Health-related quality of life (HRQoL) has recently gained importance as treatment options for tumors of the upper GI tract lead to improved long-term survival. HRQoL is often estimated by physicians even though their reliability and the impact of outside factors such as contact time and level of medical education is unclear. Therefore, in this study we investigated the correlation between physicians\', students\', and patients\' assessment of HRQoL. 54 patients presenting with tumors of the upper GI tract were included and asked to fill out the standardized HRQoL questionnaires EORTC QLQ-C30 and QLQ-OG25. Attending physicians and medical students filled out the same questionnaires through estimation of patients\' HRQoL. Correlation was assessed through Pearson\'s and Kendall\'s τb coefficients. Physicians\' and patients\' assessments correlated for one out of six of the functional and a third of the symptom scores. Students\' and patients\' assessments correlated for one third of the functional and two thirds of the symptom scores. Students tended to underestimate patients\' symptom burden while physicians tended to overestimate it. Physicians failed to correctly assess several pathognomonic symptoms in this study. Students showed higher correlation with patients\' symptoms than physicians. Even so, this adds to mounting evidence that shows the benefit of using patient-reported outcomes as a gold standard regarding HRQoL.

The primary obesity surgery endoscopic, or POSE, is an endoscopic procedure where sutures are placed in the stomach to reduce its size and achieve weight loss. This procedure is regarded as a safe procedure with little minor or major adverse events. We describe the case of a woman who presented with a perforation of the stomach lining 1 year after a POSE procedure at the site of a snowshoe anchor. This has not been described previously as a late complication. The perforation was treated surgically by removing the anchor and closing the defect. Later analysis revealed an active Helicobacter pylori infection.
