Technological achievements in the area of endoscope design and development have resulted in instruments capable of advancing beyond the reach of simple gastroscopes. Such instruments, known as enteroscopes, form the bases of small bowel endoscopy. Recent widespread use of enteroscopes have contributed significantly to the understanding of small intestinal pathology and improved the ability to diagnose and treat patients with intestinal bleeding sources.

Abstract Background Haemangioma of the small intestine is a rare disease in adult patients and is usually located in the jejunum. The usual clinical features include abdominal pain, bleeding, and obstruction. Acute intestinal bleeding leading to anaemia is the most common presentation in most patients. Intussusception and even perforation caused by cavernous haemangioma are extremely rare Case Summary we report a 31-year-old male with a right upper quadrant pain, nausea, elevated CRP. ultrasound abdomen suggestive of hepatic haemgioma whereas the CT abdomen showed left upper quadrant mass. He had laparoscopy converted the laparotomy showed5*5cm small intestine mass. small bowel resection and anastomosis was done. Histology has confirmed haemangioma. Discussion Small bowel haemangioma accounts for 5 to 10 % of all benign neoplasms of the small intestine. It is thought to be one of the congenital benign vascular lesions. Haemangiomas are classified as cavernous, capillary, or mixed type, and the cavernous type is the most common Malignant change is quite unusual. Multiple lesions are often associated with similar neoplasms in other organs, such as the liver and skin. Conclusions Small intestine haemangioma are often very difficult to diagnose. Early diagnosis and appropriate intervention could provide good outcomes. Diagnostic and therapeutic measures should be taken to avoid further complications.

Clinical Advances

The recent advances in clinically important diseases of the small intestine have been reviewed; however, the basis for many of these clinical advances rests with important observations on alterations in the physiology of the small intestine, as well as mechanistic observations of alterations in small intestinal function in models of human disease. In this review a summary of the past year's literature is presented which will draw attention to the considerable areas of progress in small bowel physiology which will soon be translated into an improved understanding of the pathophysiology of a variety of intestinal disorders.

Host Metabolism

Gut microbiome changes have been associated with human ageing and implicated in age-related diseases including Alzheimer’s disease and Parkinson’s disease. However, studies to date have used stool samples, which do not represent the entire gut. Although more challenging to access, the small intestine plays critical roles in host metabolism and immune function. In this paper (Leite et al. (2021), Cell Reports, doi: 10.1016/j.celrep.2021.109765), we demonstrate significant differences in the small intestinal microbiome in older subjects, using duodenal aspirates from 251 subjects aged 18-80 years. Differences included significantly decreased microbial diversity in older subjects, driven by increased relative abundance of phylum Proteobacteria, particularly family Enterobacteriaceae and coliform genera Escherichia and Klebsiella. Moreover, while this decreased diversity was associated with the ‘ageing process’ (comprising chronologic age, number of medications, and number of concomitant diseases), changes in certain taxa were found to be associated with number of medications alone (Klebsiella), number of diseases alone (Clostridium, Bilophila), or chronologic age alone (Escherichia, Lactobacillus, Enterococcus). Lastly, many taxa associated with increasing chronologic age were anaerobes. These changes may contribute to changes in human health that occur during the ageing process.

Small intestinal stromal tumors acccount for approximately 35% of all gastrointestinal stromal tumors. Gastrointestinal bleeding is considered as one of the main clinical symptoms for SISTs. Capsule endoscopy has brought revolution in small bowel diagnostics, as it is considered the best method of visualisation of the entire small intestine. Besides, it is well tolerated by patients and is accompanied by a low number of complications. It is also indicated as the first diagnostic method in gastrointestinal bleeding of obscure origin, following negative upper endoscopy and colonoscopy. Case report: 2 patients (a male and a female, aged 58 and 69, respectively) presented with obscure gastrointestinal bleeding have been examined by capsule endoscopy after negative upper endoscopy and colonoscopy. Videorecords have been assessed in both cases by two independent experts. The capsule reached the Bauchin-valve in both cases during the 8 hours of the testing time and the entire small bowel was clearly visible. – Based on the capsule endoscopic images, for one of the two cases a tumor has been reported as the background of the small intestinal bleeding. In the other case we could mark the location of the bleeding, while we were unable to ascertain the type of the actively bleeding lesion during the test. In order to determine the accurate bleeding source double-balloon enteroscopy was performed in the second case. After surgery the histological and immunhistochemical tests have justified the presence of spindle cell GISTs. Taking into consideration the Fletcher-classification, for the tumor size and the mitotic index, both cases can be classified as a GIST of low malignant potencial. Conclusions: An early diagnosis and application of a definitive therapy become possible by using capsule endoscopy, therefore the chance of survival of the patients might be increased.

Postoperative reflux (POR) is a well-recognized complication after colic surgery in horses, particularly when presenting small intestinal pathology. Even though much has been written about the pathophysiology and management of POR, additional clinical studies are needed to better understand and anticipate this complication. The aim of the study was to provide clinical evidence of ultrasound findings in the postoperative period (three days). The study is based on transcutaneous abdominal ultrasounds of the caudoventral abdomen during the postoperative period (three days), in 58 horses, presented for an exploratory laparotomy, and compared to 20 horses that underwent general anesthesia for an elective surgical procedure. Small intestine (SI) images and videos were analyzed for loop number, loop diameter, wall thickness, motility, and echogenic type of loop contents. Ultrasound findings of horses that had a large colon pathology were similar to those of the control group. Interestingly, horses that presented an SI pathology had significantly thicker SI walls, increased loop diameter, slower motility, and hypoechoic contents, particularly in horses that had undergone small intestinal resection and anastomosis. Although the number of horses that developed POR in our study was too small for statistical analysis, they all had the aforementioned ultrasonographic changes. Abdominal ultrasound, during the postoperative period (three days), was a useful method to identify horses with abnormal small intestinal parameters. Further investigation as to whether these parameters can be used to predict POR in a larger population is warranted.

Crohn’s disease (CD) is a disorder of uncertain etiology that is characterized by transmural inflammation of the gastrointestinal tract. CD may involve the entire gastrointestinal tract from mouth to the perianal area. Isolated jejunal involvement of CD is a rare entity. We describe a case of CD involving only jejunum with successful treatment in a 74-years-man who presented with melaena, abdominal pain and significant weight loss. Endoscopy of upper gastro-intestinal tract revealed gastritis and colonoscopy showed small sessile polyp at rectum and sigmoid colon, polypectomy was done accordingly. After few days of polypectomy, he again noticed melaena along with abdominal discomfort and weakness with loss of 4 kg weight within this periods. Diagnosis was confirmed by capsule endoscopy and serology. Treatment was thereafter started with oral steroid and mesalamine sachet. The patient is now on remission and is on regular follow up. CD has propensity to involve the distal small intestine and proximal large bowel. Affected persons usually experience diarrhea and abdominal pain, frequently accompanied by weight loss. Proximal small bowel involvement is less common than distal small bowel or colonic involvement in CD. CD involving proximal small intestine should be suspected in Asian patients with middle gastro-intestinal bleeding. It is associated with a high risk of clinical relapse and morbidity, including the need for abdominal surgery. Different modalities of baseline evaluation and more sophisticated diagnostic modalities may be required for patients with CD involving proximal small bowel. Capsule endoscopy (CE) currently plays an important role in CD. Birdem Med J 2020; 10(1): 68-72
