Attenuated Familial Adenomatous Polyposis.

A 36-year-old man was diagnosed with multiple gastric polyps by esophagogastroduodenoscopy. Subsequent colonoscopy identified two tubular adenomas, and computed tomography revealed subcutaneous tumors. Based on these findings, we suspected that gastric polyposis was associated with the APC gene, either attenuated familial adenomatous polyposis (AFAP) or gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS).

Successful endoscopic sclerotherapy with bile duct stenting for a vascular malformation neighboring the duodenal papilla in blue rubber bleb nevus syndrome.

A 14-year-old girl, who had been diagnosed with blue rubber bleb nevus syndrome, was referred to our hospital because of iron deficiency anemia. Esophagogastroduodenoscopy revealed a dark and red-colored vascular malformation occurring just above the duodenal papilla. Because the lesion was regarded as the cause of the anemia, we performed polidocanol injection therapy with bile duct stenting.

Multicenter epidemiological survey of pneumatosis intestinalis in Japan.

Background: Pneumatosis intestinalis (PI) is a rare condition characterized by gas collection in the intestinal wall. We aimed to determine the etiology and affected segments associated with complications, treatment, and outcome.

Methods: We conducted a multicenter epidemiological survey using a standardized data collection sheet in Japan.

Improvements of lung volumes and respiratory symptoms after weight loss through laparoscopic sleeve gastrectomy.

Purpose: This study evaluated the improvement of respiratory function and airway volumes using spirometry and computed tomography (CT) in severely obese Japanese patients undergoing laparoscopic sleeve gastrectomy (LSG). We also evaluated the quality of life (QOL) of enrolled patients using questionnaires.

Methods: A total of 71 patients who underwent LSG at Iwate Medical University Hospital between October 2013 and September 2020 were enrolled.

The mucin phenotype does not affect the endoscopic resection outcome of non-ampullary duodenal epithelial tumors.

Some studies have reported an association between clinicopathological features and mucin phenotypes of non-ampullary duodenal epithelial tumors (NADETs). However, the association between clinical outcomes of endoscopic resection (ER) and mucin phenotypes has not been elucidated. The aim of this retrospective study was to analyze clinical outcomes of ER of NADETs with reference to mucin phenotypes.

Prognostic nutritional index is an independent prognostic factor for older patients aged ≥ 85 years treated by gastric endoscopic submucosal dissection.

Background: Clinical outcomes and prognostic factors for survival after endoscopic submucosal dissection (ESD) in older patients aged ≥ 85 years with early gastric cancer (EGC) are not well defined. The aim of this study was to investigate the clinical outcomes and prognostic factors for survival after ESD in older patients aged ≥ 85 years with EGC.

Methods: Clinical outcomes of 70 patients aged ≥ 85 years with EGC treated with ESD were evaluated retrospectively.

Resectability of underwater endoscopic mucosal resection for duodenal tumor: A single-center, retrospective pilot study.

Background And Aim: Underwater endoscopic mucosal resection (U-EMR) has been attracting much attention as treatment for patients with nonampullary duodenal epithelial tumors (NADETs). We aim to compare treatment outcomes, including submucosal resectability, between patients undergoing U-EMR and conventional endoscopic mucosal resection (C-EMR) for NADET.

Methods: We conducted a retrospective review of 38 patients with NADET treated by U-EMR or C-EMR.

Protective effect of proton pump inhibitors and potassium competitive acid blockers against post-gastric endoscopic submucosal dissection bleeding: a single-center, propensity score-matched analysis.

Objectives: Both potassium-competitive acid blockers (P-CABs) and proton pump inhibitors (PPIs) are known to be protective against bleeding after gastric endoscopic dissection (ESD) for early gastric cancers. The aim was to compare the effect of PPI and P-CAB treatment against bleeding after gastric ESD.

Materials And Methods: This was a single-center, retrospective analysis.

Adrenal crisis presented as acute onset of hypercalcemia and hyponatremia triggered by acute pyelonephritis in a patient with partial hypopituitarism and pre-dialysis chronic kidney disease.

A 57-year-old woman with pre-dialysis chronic kidney disease (CKD) was hospitalized because of fever and fatigue. On admission, increased inflammatory response and pyuria with bacteriuria were observed. Pyelonephritis was successfully treated with antibiotics, whereas her fatigue continued and she developed progressive hypercalcemia and hyponatremia; serum sodium level, 116 mEq/L and corrected serum calcium level, 13.

Capsule endoscopy findings for the diagnosis of Crohn's disease: a nationwide case-control study.

Background: Capsule endoscopy can be used to identify the early stage of small bowel Crohn's disease (CD). We evaluated significant small bowel capsule endoscopy (SBCE) findings that can lead to early diagnosis of CD.

Methods: We retrospectively accumulated clinical and SBCE data of 108 patients (63 with and 45 without CD).
