OBJECTIVE To study the effects that pneumoperitoneum achieved through carbon dioxide insufflation has on diaphragmatic excursion in pigs. METHODS A total of 14 male Landrace pigs, 30 to 45 days of age and weighing five to seven kilograms each, were used. The sample was randomly and equally divided into two groups: one (n = 7) in which pneumoperitoneum was maintained at 10 mmHg for 60 minutes;...

A 6-year-old intact male Jindo dog was presented for reduced appetite, depression, and tympanic abdominal distension. Abdominal radiographs showed severe pneumoperitoneum an intestinal mass. Computed tomography revealed massive associated with perforation, cervical thoracoabdominal wall emphysema, pneumomediastinum, pneumoretroperitoneum, pneumoscrotum, peritonitis. Surgery confirmed a ruptured...

Acute appendicitis is a rare condition in neonates, with a high mortality. If perforated, it seldom presents with radiologically significant pneumoperitoneum. An 11-day-old newborn presented with abdominal distension and reluctance to feeds. X-ray abdomen revealed significant pneumoperitoneum. After optimization of his condition, exploratory laparotomy was performed. Perforated appendix was fou...

FIG lo-Erect chest radiograph showing a large pneumoperitoneum with air under both diaphragms. The right hemidiaphragm is raised. Dilated air filled loops of bowel are projected overthe liver (arrows)-both sides ofthe bowel wall can be seen (Rigler's sign). Summary Diagnostic quality Alignment of bones Bone margins and density Cartilage and joints Soft tissues Bowel gas pattern Pneumoperitoneum...

We present our experience with 5 patients, all of whom were noted to have radiological signs of pneumoperitoneum in the absence of clinical features of peritonitis. All 5 cases were eventually shown to be due to causes not requiring surgery. We review the numerous unusual causes of pneumoperitoneum which do not require urgent surgical intervention and emphasize their importance in cases where t...

The following case study is presented to illustrate the concept that recovery from the invariably disastrous effects of arterial air embolism, accidentally Incurred during the therapeutic administration of pneumoperitoneum, may be possible if certain recognized and specific maneuvers are practiced correctly. This particular subject is of extreme importance because since the institution of pneum...

Gastric perforation in neonates is a rare but frequently fatal condition of uncertain etiology. It usually occurs in infants requiring resuscitation or having an episode of hypoxia following birth (1). Although massive pneumoperitoneum is a consistent radiographic characteristic in most of the cases, a few reports have highlighted unusual imaging findings in neonatal gastric perforation (2). He...

INTRODUCTION Necrotizing enterocolitis (NEC) is a common in neonatal intensive care unit (NICU) patients; especially in premature and low birth weight ones. Surgery is indicated when there is pneumoperitoneum. Other therapies include conservative observation or primary peritoneal drain (PPD). This study was conceived to evaluate peritoneal tapping, rather than primary peritoneal drain (PPD) as ...

Pneumatosis intestinalis is an uncommon disorder characterized by an accumulation of gas in the bowel wall. We described three cases undertaking liver transplantation. The patients developed diarrhea in three cases and high fever in two. An abdominal X-ray and computed tomography scan demonstrated extensive pneumatosis intestinalis in the colon with pneumoperitoneum mimicking hollow organ perfo...
