BACKGROUND: Intersigmoid hernia is a hernia of the small intestine into the intersigmoid fossa. Because the cavity of the intersigmoid fossa is so small, the preoperative detection of incarcerated intestine and/or mesenteric convergence is very difficult. We report a case of intersigmoid hernia in which the incarcerated bowel and mesenteric convergence could be visualized by oblique multiplanar reconstruction (MPR) images on multi-detector computed tomography (MDCT). CASE REPORT: An 82-year-old man with small bowel obstruction was treated conservatively with a long intestinal tube...

BACKGROUND: Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract, with an average length of 3 cm. Complications occur in 6.4% and most commonly include inflammation and gastrointestinal bleeding. Preoperative diagnosis is demanding and achieved in 4%. CASE REPORT: A 34-year-old otherwise healthy patient presented with an acute abdomen due to small bowel obstruction. Computed tomography scan could not identify the underlying cause...

Trichobezoars are an uncommon cause of acute abdominal pain. We present a case of a 12-year-old girl with a history of a trichobezoar who presented to the emergency department with acute abdominal pain. Abdominal sonography was performed which suggested portal venous gas and showed complex peritoneal fluid. Subsequent computed tomography demonstrated both gastric and small bowel bezoars, with a jejunojejunal intussusception, and confirmed portal venous gas and complex ascites. At the time of surgery, there was evidence of intestinal and biliary perforation...

Port site hernias are emerging as a problematic complication of laparoscopic surgery. The aim of this study was to elucidate the characteristics of port site hernias and determine the long-term outcomes based on the interval between primary surgery and hernia occurrence. Twenty-four patients were surgically treated for trocar site hernia between 1997 and 2013. The patients were grouped into early-onset group (EOG; less than one month) and late-onset group (LOG; more than one month) based on the interval between laparoscopic surgery and hernia onset...

Ultrasonography (US) is widely used to evaluate most body parts in pediatric patients because it is simple, noninvasive, easy to use, and applicable in a wide variety of clinical situations. US is the modality of choice for the initial evaluation of acute abdominal pain in pediatric patients because of their small body habitus and the presence of less fat tissue in the abdominal wall and peritoneal cavity. The most important factor in performing pediatric emergency US is the graded compression technique and selection of the proper transducer...

Pelvic organ prolapse is a major health problem in women where pelvic floor organs (bladder, uterus, small bowel, and rectum) fall from their normal position and bulge into the vagina. Dynamic Magnetic Resonance Imaging (DMRI) is presently used to analyze the organs' movements from rest to maximum strain providing complementary support for diagnosis. However, there is currently no automated or quantitative approach to measure the movement of the pelvic organs and their correlation with the severity of prolapse...

Wireless Capsule Endoscopy (WCE) is a standard non-invasive modality for small bowel examination. Recently, the development of computer-aided diagnosis (CAD) systems for gastrointestinal (GI) bleeding detection in WCE image videos has become an active research area with the goal of relieving the workload of physicians. Existing methods based primarily on handcrafted features usually give insufficient accuracy for bleeding detection, due to their limited capability of feature representation. In this paper, we present a new automatic bleeding detection strategy based on a deep convolutional neural network and evaluate our method on an expanded dataset of 10,000 WCE images...

BACKGROUND: Our group has previously published a retrospective review defining variables predictive of transmural bowel ischemia in the setting of pneumatosis intestinalis (PI). We hypothesize this prospective study will confirm the findings of the retrospective review, enhancing legitimacy to the predictive factors for pathologic PI previously highlighted. METHODS: Data were collected using the Research Electronic Data Capture. Forward logistic regression was utilized to identify independent predictors for pathologic PI...

Gastric heterotopia refers to the discovery of normal gastric tissue at foreign, unexpected sites. It has been described anywhere in the alimentary tract, even in the mediastinum, scrotum, and spinal cord. It is not uncommonly seen in the oesophagus or small intestine. However, large bowel lesions are rare, with the most common location of colonic lesions is the rectum. Although it is a rare entity, it may be the source for significant problems such as rectal bleeding, abdominal pain, deep rectal pain, and malignancy...

Urinary lithiasis is a prevalent disorder of uncertain origin which provokes health problems through potential harm to the urinary system, renal parenchyma or the body as a whole, with a frequent trend to relapse. Historically urinary calculi have been studied and treated as an isolated disease but nowadays we know more about their connection with other pathological entities. In a small percentage of patients, diseases like primary hyperparathyroidism, tubular renal acidosis, inflammatory bowel disease or bariatric surgery have a fairly well studied physiopathological link with kidney stones...

BACKGROUND: Diagnosis of protein loss into the gastrointestinal tract using noninvasive techniques is challenging. In people, scintigraphy not only is a sensitive tool to confirm protein-losing enteropathy (PLE), but it also allows for localization of protein loss. HYPOTHESIS/OBJECTIVES: To investigate the feasibility of (99m) Tc-labeled human serum albumin (HSA) scintigraphy in dogs with PLE in comparison with control dogs. ANIMALS: A total of 8 clinically healthy control research dogs and 7 client-owned dogs with gastrointestinal clinical signs and hypoalbuminemia (serum albumin concentration <2...

BACKGROUND & AIMS: Endoscopists do not routinely follow guidelines to survey individuals with low-risk adenomas (LRAs, 1-2 small tubular adenomas, less than 1 cm) every 5-10 years for colorectal cancer (CRC)-many endoscopists recommend shorter surveillance intervals for these individuals. We aimed to identify reasons that endoscopists recommend shorter surveillance intervals for some individuals with LRAs and determine whether timing affects outcomes at follow-up examinations. METHODS: We collected data from 1560 individuals (45-75 years old) who participated in a prospective chemoprevention trial (of vitamin D and calcium) from 2004 through 2008...

Carcinoid tumors are the most common form of gut neuroendocrine tumors, however, they rarely present with small bowel obstruction. We present a case of a 65-year-old woman without prior abdominal operations who presented with symptoms of small bowel obstruction. Computed tomography (CT) showed multiple air fluid levels and a transition point in the left mesentery with two soft tissue densities at the same level. The patient was taken to the operating room for surgical exploration, which showed two intramural masses in the mid and distal jejunum, which surgical pathology showed to be stage IIIB carcinoid tumor...

PURPOSE: One of the rarest gastrointestinal neoplasm is small bowel cancer. Experience with its treatment modalities is limited. Stereotactic ablative radiation therapy (SABR) has improved, with image-guided radiation therapy becoming a curative option in many tumors. Especially when surgery cannot be performed due to comorbidities, SABR provides a good toxicity profile and an excellent tumor control rate owing to its specific schedule: high dose on a limited and well-defined area. METHODS: An 83-year-old man had arterial hypertension and congestive cardiomyopathy, with recent history of upper abdominal pain, weight loss over 10 kg, and progressive severe fatigue...
