PURPOSE: Transthoracic examination of the heart and great vessels is an essential skill that allows the anesthesiologist to evaluate cardiac function. In this article, we describe a pragmatic technique to obtain the essential views to evaluate normal or abnormal cardiac function and to appreciate great vessel anatomy and physiology. PRINCIPAL FINDINGS: The cardiac anatomy and function can be described using standard parasternal, apical, and subcostal views. These windows can also be used to assess the aorta, pulmonary artery, and vena cavae; however, other transthoracic and abdominal windows can be used to complete the evaluation of the great vessels...

INTRODUCTION: True left-sided gallbladder (LSG) is a rare finding that may present with symptoms similar to those of a normally positioned gallbladder. Moreover, it may be missed by preoperative imaging studies such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), or endoscopic ultrasound. True left-sided gallbladder is a surgical challenge and surgical technique may need to be modified for the completion of laparoscopic cholecystectomy. PRESENTATION OF CASE: In this case report, we present a case of true left-sided gallbladder that produced right-sided abdominal symptoms...

A 67-year-old man who presented with a bloody stool was diagnosed with ascending colon cancer. He had previously experienced thoracic and abdominal aortic dissections, which were treated with thoracic and abdominal aortic grafts and superior mesenteric artery revascularization. We performed a laparoscopic right hemicolectomy with a D3 lymph node dissection. During the laparotomy, we identified the superior mesenteric artery and an enlarged anterior superior pancreaticoduodenal artery. Injury to the latter artery could lead to severe ischemia in multiple organs; therefore, it was crucial to identify the primary feeding artery and vascular anatomy before and during surgery...

REVIEW
Robert O Heuckeroth
Hirschsprung disease is defined by the absence of enteric neurons at the end of the bowel. The enteric nervous system (ENS) is the intrinsic nervous system of the bowel and regulates most aspects of bowel function. When the ENS is missing, there are no neurally mediated propulsive motility patterns, and the bowel remains contracted, causing functional obstruction. Symptoms of Hirschsprung disease include constipation, vomiting, abdominal distension and growth failure. Untreated disease usually causes death in childhood because bloodstream bacterial infections occur in the context of bowel inflammation (enterocolitis) or bowel perforation...

INTRODUCTION AND HYPOTHESIS: Defining patient characteristics that alter vascular anatomy at the sacrum is critical for avoiding life-threatening bleeding at the time of sacrocolpopexy. We tested the hypothesis that in thinner/older women, the bifurcations of the aorta and inferior vena cava (IVC) are lower relative to S1 resulting in less space accessible for suture/mesh placement, placing this group at increased risk of major vascular injury. METHODS: In a retrospective cross-sectional study, CT scans were used to make 2D measurements and a 3D model of the aorta/IVC, intervertebral disc space, and bony anatomy using segmentation and modeling software...

PURPOSE/OBJECTIVES: SBRT is used to treat oligometastatic or unresectable primary abdominal malignancies, although ablative dose delivery is limited by proximity of organs-at-risk (OAR). Stereotactic, magnetic resonance (MR)-guided online-adaptive radiotherapy (SMART) may improve SBRT's therapeutic ratio. This prospective Phase I trial assessed feasibility and potential advantages of SMART to treat abdominal malignancies. MATERIALS/METHODS: Twenty patients with oligometastatic or unresectable primary liver (n = 10) and non-liver (n = 10) abdominal malignancies underwent SMART...

This manuscript describes the anatomy of the lower respiratory tract in domestic bird species including the chicken and pigeon. The here described anatomical structures play a major role avian respiration, which is fundamentally different from respiration in mammals. During inspiration and expiration, a continuous caudocranial airflow is present within the tertiary bronchi of the Paleopulmo, while the Neopulmo, which is only present in phylogenetically recent species, is characterized by tidal respiration. Various anatomical structures and aerodynamic mechanisms have been described in an attempt to explain the proposed mechanism of respiration...

RATIONALE: Heterotaxy with polysplenia is an extremely rare congenital condition resulting from abnormal arrangement of organs in the abdominal and thoracic cavities during embryologic development. When a malignancy such as pancreatic cancer develops under these conditions, surgical resection becomes particularly complex. This case report demonstrates successful pancreatic cancer resection despite the patient's complicated anatomy. PATIENT CONCERNS: An 82-year-old female presented to our institution with complaints of mild right upper quadrant pain radiating to the mid-epigastric region...

Lindsay Edwards, Lisa Hui
Fetal structural anomalies are found in up to 3% of all pregnancies and ultrasound-based screening has been an integral part of routine prenatal care for decades. The prenatal detection of fetal anomalies allows for optimal perinatal management, providing expectant parents with opportunities for additional imaging, genetic testing, and the provision of information regarding prognosis and management options. Approximately one-half of all major structural anomalies can now be detected in the first trimester, including acrania/anencephaly, abdominal wall defects, holoprosencephaly and cystic hygromata...

The acute abdomen is a term used to characterize an animal presented as an emergency, in a more or less severe critical state, and for which medical and possibly surgical treatment will be necessary. To succeed, the clinician should use a systematic approach, have an excellent knowledge of the bovine abdominal anatomy, and have a good understanding of the pathophysiology of abdominal pain. Good clinical judgment, critical analysis, and good client communication skills are also essential. This article presents and discusses those necessary skills in the context of field practice...

INTRODUCTION: The development of new surgical approaches for the management of congenital abdominal wall defects may be facilitated by using an animal model. However, because the anatomy of the neonatal abdominal wall has not been described, a suitable model is yet to be identified. We aimed to evaluate and define the neonatal abdominal wall musculature using ultrasound, to be used as a reference to identify an appropriate animal model for the neonatal abdominal wall in the future. METHODS: Infants with a postconceptual age of less than one month weighing between 2 and 3 kg were eligible...
