Pneumoperitoneum in preterm infants is a surgical emergency as it is usually indicative of intestinal perforation. Rare cases of idiopathic pneumoperitoneum have been described in the literature, the underlying causes and pathophysiology of which remain uncertain. We present a case of pneumoperitoneum in an extremely preterm infant with severe growth restriction. This occurred while she was receiving high frequency oscillatory ventilation. She had respiratory distress syndrome with pulmonary interstitial emphysema...

Tension pneumoperitoneum is a relatively rare occurrence in the pediatric population. However, tension pneumoperitoneum is associated with significant morbidity and mortality if it is not promptly diagnosed and treated. A 5-year-old girl was admitted to emergency department with abdominal pain. She was in shock, and the radiograph film of the abdomen revealed a voluminous tension pneumoperitoneum. Aggressive fluid challenges were performed in intensive care followed by urgent laparotomy. Primary abdominal compartment due to trapped gas caused a decreased venous return and visceral perfusion...

BACKGROUND: Laparoscopic hysterectomies comprise a large proportion of all hysterectomies in the United States. Procedures completed under regional anesthesia pose a number of benefits to patients, but laparoscopic hysterectomies traditionally have been performed under general anesthesia. We describe a case of total laparoscopic hysterectomy under epidural anesthesia with the patient fully awake. CASE: A 51-year-old woman with abnormal uterine bleeding underwent an uncomplicated total laparoscopic hysterectomy, bilateral salpingectomy, and excision of endometriosis...

Pneumoperitoneum, usually seen as free air under the diaphragm, is a finding that can be seen on plain abdominal radiographs, signifying a leakage of air, usually from a perforation in the gastrointestinal tract. There are several other potential pathways from other body compartments for air to enter the abdominal cavity. Pneumoperitoneum does not always signify bowel rupture, as it can also result from pneumomediastinum and pneumothorax, and in patients who are being mechanically ventilated. Patient history and physical examination can assist in a preliminary diagnosis before diagnostic imaging...

We report an unusual presentation of annular pancreas with pneumoperitoneum in a newborn with an associated left sided Erb's palsy. The neurological deficit caused considerable confusion in the diagnosis and unexpected complications after surgery. We highlight the importance of clinical examination and the complications that an Erb's palsy can cause. This unusual triad of Erb's palsy, eventration of diaphragm and annular pancreas has hitherto not been described in literature.

Invasive aspergillosis is an important cause of morbidity and mortality in patients who have undergone lung transplantation. Aspergillus infections usually involve the respiratory tract, with vascular invasion and subsequent dissemination. However, acute appendicitis associated with localized aspergillosis is rare, especially among patients who have undergone prophylaxis with voriconazole. We present a case of primary Aspergillus appendicitis diagnosed by histologic examination in a patient who underwent lung transplantation...

INTRODUCTION: Recently, magnetic solutions have been proposed to minimize surgical invasiveness. These are comprised of deployable instruments containing magnets which are inserted into the abdominal cavity through a single access point. The manipulation of the internal elements occurs via magnets held on the external surface of the abdominal wall. This technology relies on the magnetic force between the magnets, which is inversely related to the abdominal wall thickness (AWT). The aim of this study was to establish the expected change in AWT from before and after initiation of pneumoperitoneum...
