OBJECTIVE To review causes of nonsurgical pneumoperitoneum (NSP), identify nonsurgical etiologies, and guide conservative management where appropriate. DATA SOURCE We conducted a computerized MEDLINE database search from 1970 to 1999 by using key words pneumoperitoneum and benign, nonsurgical, spontaneous, iatrogenic, barotrauma, pneumatosis, diaphragmatic defects, free air, mechanical ventil...

The object of this paper is to present a modified view of the mode of action of phrenic nerve crush and pneumoperitoneum therapy in pulmonary tuberculosis. In a study of mediastinal shift in a series of 80 cases of phrenic nerve crush and pneumoperitoneum therapy (Fox, 1950) it was found that the average mediastinal shift to the left in the cases with right phrenic paralysis was 1.6 cm., and to...

BACKGROUND Tension pneumoperitoneum is a rare surgical emergency in which free intraperitoneal gas accumulates under pressure. The known sources of free gas are perforated hollow viscera. We believe this is the first published case of a tension non-perforation pneumoperitoneum secondary to anaerobic gas production. This occurred in a background of primary non-aerobic bacterial peritonitis, whic...

INTRODUCTION Tension pneumoperitoneum is defined as the massive accumulation of air in the peritoneal cavity, which results in a sudden increase in intraabdominal pressure. Various iatrogenic procedures are responsible for this complication. We herein report a case of tension pneumoperitoneum resulting from upper gastrointestinal endoscopy. CASE DESCRIPTION A 45-y-old man was referred to our...

Several reports in the literature concern animal experiments with pneumoperltoneum and none of these describes any significant local pathologic changes attributed to the presence of air in the peritoneal space.’ Trimble, Eaton and Moore,2 in 1939, reported necropsy findings In 20 patients who had received pneumoperitoneum for varying lengths of time prior to death. Less than half showed any mnt...

PURPOSE: To investigate the potential protective effects of enoxaparin against the adverse events of carbon dioxide (CO2) pneumoperitoneum. METHODS: Thirty four rats were divided into three groups: Group 1 (sham) underwent insertion of Veress needle into the abdomen and 90 min of anesthesia with no gas insufflation. The animals in control and enoxaparin groups were subjected to 90 min of 14 m...

Veress needle insertion, direct trocar insertion and open technique are different methods of establishing pneumoperitoneum to perform a successful laparoscopic procedure. We conducted this study to compare the use of a Veress needle and direct trocar insertion to create pneumoperitoneum. 274 laparoscopic cholecystectomy operations were evaluated. There were no significant differences in the age...

Background: Prospective analytical study to evaluate the Veress needle technique for creating pneumoperitoneum in terms of safety profile. Materials and methods: A total of 4,014 patients undergoing laparoscopic surgery for different reasons in which Veress needle was the technique to create pneumoperitoneum were included in the study during the period of January 2008 to September 2012. Results...

We assessed the cardiorespiratory effects of laparoscopic procedures in 27 infants aged between 36 and 365 days. Infants were monitored and anaesthetised in a standardised manner. Heart rate, mean arterial pressure, end-tidal carbon dioxide and oxygen saturation were recorded, and blood gases were measured at 5 min after intubation, 15 and 30 min after carbon dioxide pneumoperitoneum, 5 min aft...

Abstract Introduction Simultaneous pneumoperitoneum and pneumomediastinum is a rare radiological finding. There are only 6 reported cases in the literature of this being due to diverticular perforation. Case report A 78-year-old male presented with worsening shortness breath, lower back pain abdominal pain. Past medical history included myasthenia gravis, for which he took pyridostigmine. compu...
