small bowel obstruction

Biliary endoprostheses are widely used in the treatment of biliary lithiasis, malignant and benign strictures, and occasionally in long-lasting biliary fistulas. They can be placed endoscopically during endoscopic retrograde cholangiopancreatography and radiologically (percutaneous) when the endoscopic route is not feasible. Complications associated with the endoscopic placement of biliary endoprostheses are well described in the literature, with migration being the most common. Intestinal obstruction is a rare complication associated with the migration of these devices...

Introduction: Small bowel obstruction (SBO) is a common cause of hospital admission leading to resource utilization. The majority of these patients require non-operative management (NOM) which can lead to increased length of stay (LOS), readmissions, resource utilization, and throughput delays. Early surgical consultation (SC) for SBO may improve efficiency and outcomes. Methods: We implemented an institution-wide intervention (INT) to encourage early SC (<1 day of diagnosis) for SBO patients in July 2022...

Introduction A computed tomography (CT) scan and point-of-care ultrasound (POCUS) are commonly employed for diagnosing small bowel obstructions (SBOs). Prior studies demonstrated that POCUS has 90-95% sensitivity and specificity compared with CT scanning, which is the gold standard. Unlike other imaging modalities (in which the ordering and performing clinician are not the same), POCUS-performing/interpreting sonologists must recognize the risk of confirmation bias in the POCUS application. Per Bayesian analysis, the likelihood of a diagnosis being true following a diagnostic test is based on the ordering clinician's pre-test probability and the test characteristics (sensitivity and specificity, from which positive and negative likelihood ratios can be calculated)...

We present the case of an elderly man with a history of diastolic congestive heart failure, severe aortic stenosis and atrial fibrillation, who presented with fatigue, weakness, coffee ground emesis and black tarry stool. Haemoglobin was 68 g/L. Lactate dehydrogenase was elevated at 1038. Evaluation by cardiology and gastroenterology specialists revealed reflux oesophagitis and a mild hiatal hernia on oesophagogastroduodenoscopy, normal colonoscopy and small bowel series without obstruction. Capsule endoscopy identified angiodysplasia in the small intestine...

INTRODUCTION: Gastric outlet obstruction presents with a range of symptoms which include abdominal pain, early satiety, weight loss and vomiting caused obstruction secondary to tumors from outside the gastrointestinal tract or due to motility disorders. Bladder cancer is rarely associated with Gastric outlet obstruction. It usually presents with painless hematuria and urinary symptoms. Squamous cell carcinoma is a subtype of bladder malignancies that tends to present at a later stage and is associated with poorer prognosis in terms of metastasis and survival...

Foreign body ingestion is an infrequent cause of small bowel obstruction and, rarely, perforation. It is a common occurrence among pediatric patients, mentally impaired and the edentulous elderly population majority of which will pass through the gastrointestinal tract uneventfully. The likelihood of complications such as perforation, bleeding or fistula formation increases markedly particularly for sharp, stiff, and elongated objects (i.e. toothpicks, meat bones, pins, and razor blades). Diagnosis can be difficult as frequently patients are incognizant of the nature and time of ingestion...

INTRODUCTION/IMPORTANCE: Peritoneal encapsulation (PE) is a rare congenital anomaly characterised by the presence of an accessory peritoneal membrane which encases part of the small bowel. Typically, this remains asymptomatic, however; in rare cases, a person may present with symptoms suggestive of a small bowel obstruction. CASE PRESENTATION: Here we present a case of a 58 year old gentleman with congenital PE causing a bowel obstruction which was revealed on commuted tomography scan...

INTRODUCTION: Hematomas are a rare cause of intestinal obstruction. Subcutaneous heparin can bring about direct punctures on small bowel loops, potentially leading to traumatic hematoma and intestinal obstruction. CASE REPORTS: We present three cases of pediatric patients with clinical signs of intestinal obstruction treated with subcutaneous heparin. Two cases had increased acute-phase reactants and radiological signs of intestinal suffering, so surgical treatment was decided upon, with intramural hematoma emerging as an intraoperative finding...

•Adverse events of pembrolizumab have been documented, but more severe gastrointestinal effects are not as well described.•We report a case of a patient with cervical cancer treated with pembrolizumab who developed small bowel obstruction (SBO)•Histological analysis and gastrointestinal workup points to pembrolizumab as likely cause of SBO.

BACKGROUND: The majority of small bowel obstructions (SBO) are caused by adhesion due to abdominal surgery. Internal hernias, a very rare cause of SBO, can arise from exposed blood vessels and nerves during pelvic lymphadenectomy (PL). In this report, we present two cases of SBO following laparoscopic and robot-assisted lateral lymph node dissection (LLND) for rectal cancer, one case each, of which obstructions were attributed to the exposure of blood vessels and nerves during the procedures...

This case report describes an atypical small bowel obstruction in a 71- years old cannabis user and how point-of-care of ultrasound (PoCUS) helped to its management by further orientating the physician toward the bowel obstruction etiology, namely intussusception. Intussusception is the invagination of an intestinal segment into the adjacent segment. The acute clinical presentation of intussusception often has non-specific symptoms, and the diagnosis can be challenging. While the most common etiology is neoplasm, intussusception also occurs in bowel motility disorder such as after cannabis use...

Burkitt lymphoma (BL) is a neoplasm of the lymphoid tissue and one of the most prevalent malignancies worldwide. Classically, these patients present with unregulated B-cell differentiation causing fever, chills, night sweats, and weight loss. Although more common in children, in sporadic Burkitt lymphoma, symptoms often can be present in the abdomen. These patients also additionally report nausea, vomiting, and abdominal distention, which in rare instances can cause small bowel obstruction (SBO). Early detection and the initiation of chemotherapy remain highly effective in providing adequate care...

Internal hernia is an uncommon cause of mechanical small bowel obstruction. This case report details a 66-year-old Chinese male with no prior abdominal surgeries who presented with colicky abdominal pain, abdominal distension, and vomiting. Initial investigations were unyielding, but escalating symptoms prompted a diagnostic laparoscopy. Laparotomy then revealed a closed-loop obstruction through a lateral type pericecal hernia, with a segment of ischemic jejunum. Adhesion bands in the right iliac fossa and a congenital hernia orifice in the mesentery were identified and addressed...

We report the case of a woman presenting with small bowel obstruction secondary to an enterolith that formed within a jejunal diverticulum. Prior to this acute presentation, the patient had experienced regular abdominal pain albeit not as severe as the current episode. The CT scan on admission required review by two consultant radiologists before the cause of the small bowel obstruction was diagnosed. Successful surgical management was performed involving a laparotomy, small bowel enterotomy, and removal of the enterolith...

INTRODUCTION: Small bowel diverticula are a rare entity and are mostly found in the duodenum on diagnosis. Some common complications of this pathology include bleeding, obstruction, diverticulitis, and perforation. Furthermore, there is growing evidence supporting an association between biologic therapies and spontaneous intestinal perforation. PRESENTATION OF CASE: We present a case of a 79-year-old female on prednisone, hydroxychloroquine, and tofacitinib for rheumatoid arthritis who was misdiagnosed with transverse colonic diverticulitis and eventually found to have perforated jejunal diverticulitis on laparotomy...

AIM: Reporting of participant descriptors in studies of adhesive small bowel obstruction (ASBO) can help identify characteristics associated with favourable outcomes and allow comparison with other studies and real-world clinical populations. The aim was to identify the pattern of participant descriptors reported in studies assessing interventions for ASBO. METHOD: This systematic review was registered with PROSPERO (CRD42021281031) and reported in line with the PRISMA checklist...

INTRODUCTION: Early reports of PD-1 inhibition in ovarian clear cell carcinomas (OCCC) demonstrate promising response. We evaluated the combination of pembrolizumab and IDO-1 inhibitor epacadostat in patients with recurrent OCCC. METHODS: This single arm, two-stage, phase 2 trial included those with measurable disease and 1-3 prior regimens. Patients received intravenous pembrolizumab 200 mg every 3 weeks and oral epacadostat 100 mg twice a day. Primary endpoint was overall response rate (ORR), secondary endpoints were toxicity, progression-free survival (PFS) and overall survival (OS)...

BACKGROUND: Small bowel obstruction can occur during pregnancy, which, if missed, can lead to dire consequences for both the mother and foetus. Management of this condition usually requires surgical intervention. However, only a small number of patients are treated conservatively. OBJECTIVE: The objective was to review the literature to determine the feasibility of conservative management for small bowel obstruction. METHODS: A systematic search of the PubMed and Embase databases was performed using the keywords [small bowel obstruction AND pregnancy]...

BACKGROUND: Intramural hematoma of the small bowel is a rare yet acute gastrointestinal condition typically linked with impaired coagulation function, often posing diagnostic challenges. It is principally encountered in patients undergoing prolonged anticoagulant therapy, specifically warfarin. CASE PRESENTATION: We reported a case of intramural hematoma associated with warfarin use. The patient was admitted to hospital with abdominal pain and had received anticoagulant therapy with warfarin 2...
