Pneumatosis intestinalis (gas in the bowel wall) is often a benign condition, but it may mimic bowel ischemia or infarction and lead to unnecessary surgical intervention, especially when associated with pneumoperitoneum. We present a case of benign pneumatosis intestinalis with massive pneumoperitoneum and discuss various distinguishing features that may aid in its diagnosis.

Peptic ulcer perforation is the most common cause of pneumoperitoneum (75%). The rate of the perforation of acute appendicitis is 20-30% and the rate of its co-occurrence with pneumoperitoneum is 0-7%. In this report, a patient with sub-diaphragmatic free air due to perforated appendicitis.

The main stream of intraabdominal surgery has changed from laparotomy to laparoscopy, but anesthetic care for laparoscopic surgery is challenging for clinicians, because pneumoperitoneum might aggravate respiratory mechanics and arterial oxygenation. The authors reviewed the literature regarding ventilation strategies that reduce deleterious pulmonary physiologic changes during pneumoperitoneum...

We describe a 64 year old woman with a 3-year history of scleroderma who presented as an emergency with increasing painless abdominal distention. Radiological investigations revealed a pneumoperitoneum in the absence of either visceral perforation or pneumatosis cystoides intestinalis. This is only the fourth report of spontaneous benign pneumoperitoneum complicating scleroderma without pneumat...

since co2 pneumoperitoneum is the dominant method of laparoscopic exposure due to facility and good view, its physiologic effects are most relevant to the surgeons. co2 pneumoperitoneum may affects hemodynamics by increased intra-abdominal pressure (iap) and the physiologic effects of absorbed co2. the adverse effects of both mechanisms relate directly to the duration of the pneumoperitoneum an...

BACKGROUND Abdominal pain and shoulder tip pain after laparoscopic cholecystectomy are distressing for the patient. Various causes of this pain are peritoneal stretching and diaphragmatic irritation by high intra-abdominal pressure caused by pneumoperitoneum . We designed a study to compare the post operative pain after laparoscopic cholecystectomy at low pressure (7-8 mm of Hg) and standard pr...
