Idiopathic pneumoperitoneum

Pneumoperitoneum refers to the presence of free air in the abdominal cavity, typically indicating viscus perforation requiring urgent surgical intervention. Occasionally, pneumoperitoneum occurs without organ perforation, termed 'spontaneous' or 'non-surgical' pneumoperitoneum. We present the case of a 65-year-old male referred to the emergency department after a seizure episode. The patient reported no abdominal pain or fever, and examination revealed no other signs of peritonitis. An erect chest X-ray showed air under the diaphragm, and a subsequent computed tomography (CT) scan confirmed free intraperitoneal air in the abdomen...

INTRODUCTION AND IMPORTANCE: Acute colonic pseudo-obstruction (ACPO) is an uncommon phenomenon that is especially rare in young patients and can result in bowl ischemia and perforation if left untreated. Furthermore, pneumoperitoneum is almost always a concerning imaging finding and in the context of recent colonic resection may be a sign of anastomotic leakage. CASE PRESENTATION: We describe a case of a young female patient with postpartum ACPO who subsequently underwent a hemicolectomy with colorectal anastomosis...

Most cases of pneumoperitoneum with associated peritonitis are due to perforation of a hollow viscus. In cases where hollow viscus perforation is not the cause, the pneumoperitoneum is classified as spontaneous and typically can be further subcategorized into thoracic, abdominal, gynecologic, and idiopathic categories. Spontaneous pneumoperitoneum is classically seen in asymptomatic patients, however in a small number of cases patients can present with a concomitant peritonitis. This case report presents a patient that had signs of sepsis and peritonitis with moderate pneumoperitoneum on computed tomography (CT) imaging but was found to have no perforated hollow viscus after an extensive operative and non-operative work up...

INTRODUCTION: Pneumatosis cystoides intestinalis (PCI) is a condition characterized by the presence of gas-filled cyst-like structures in the submucosa and subserosa of the small or large intestine and in some cases accompanied by pneumoperitoneum. PCI is commonly considered a benign condition as opposed to pneumatosis intestinalis in life-threatening conditions such as mesenteric ischemia. Only a minority of cases of PCI are assumed to be primary or idiopathic with the majority being caused by a variety of underlying conditions...

Idiopathic spontaneous pneumoperitoneum (ISP) refers to intraperitoneal air of unknown origin when other more common etiologies such as traumatic, intrathoracic, and gynecologic etiologies have been excluded. We present a case of a 42-year-old woman with insignificant history presenting with ISP who underwent exploratory laparoscopy and thorough diagnostic workup that was ultimately unrevealing. This case report adds to the existing literature of ISP, and the authors recommend initiating a multi-institutional database to improve our understanding of ISP and contribute to developing consensus guidelines for presumed ISP...

Pneumoperitoneum is defined as the presence of free air in the abdominal cavity. The most common cause of pneumoperitoneum is intestinal perforation, which usually requires surgical intervention. Nonsurgical pneumoperitoneum (NPS) is defined as the presence of free air in the abdominal cavity without visceral perforation by an intrathoracic route, which commonly occurs in patients on mechanical ventilation in intensive care units. NSP, when properly diagnosed, can be successfully treated conservatively without surgery, and intensivists and surgeons should be aware of this entity associated with mechanical ventilation to avoid unnecessary surgical intervention...

Idiopathic pneumoperitoneum (IP) cases are rare and presents with varying symptoms, which makes propositions of standard treatments, clinically impracticable. There are limited IP therapies in the literature, necessitating a need, to continually highlight unique cases for the purpose of clinical education and training. This case describes an IP and management of a 34-year-old male who recently underwent a laparoscopic cholecystectomy. Patient presented to the emergency room with recurrent gastrointestinal (GI) symptoms...

Spontaneous idiopathic pneumoperitoneum (SIP) is a rare condition in the surgical practice. We introduce a case of an alcoholic male who presented with nausea, vomiting and diarrhea without clinical signs of peritonitis. A computed tomography of the abdomen showed free air distributed mainly along the ascending colon. We performed an emergency laparoscopy, which revealed no signs of perforation or bowl ischemia but showed air bubbles in the mesentery along the ascending colon. Subsequent endoscopy revealed unclassified inflammatory bowel disease manifesting in the rectum, erythematous mucosa and epithelialized erosions of the stomach...

INTRODUCTION: achalasia is a chronic disease. Since there is no curative treatment, diagnosed patients have pharmacological and/or surgical techniques available, aimed at minimizing the condition. POEM appears as a promising new type of palliative treatment with good rates of symptom improvement. OBJECTIVE: evaluate the profile of POEM at the Clinical Hospital of the Federal University of Pernambuco (HC - UFPE) and correlate it with the world scenario. METHODS: data collection was performed retrospectively from September 2017 to October 2019 with all patients undergoing POEM at the HC - UFPE...

The authors present a patient with COVID-19 and spontaneous idiopathic pneumoperitoneum. A 77-year-old man suffering from coronary artery disease, diabetes mellitus and cognitive disorders was diagnosed with bilateral pneumonia and COVID-19. Oxygen support through a face mask was prescribed. After 21 days, oxygen saturation decrease and mild abdominal symptoms required CT-based examination. Pneumoperitoneum without pneumothorax and pneumomediastinum was revealed. Explorative laparotomy found no abdominal diseases...

Pneumatosis cystoides intestinalis (PCI) is a rare entity characterized by the presence of gaseous cystic within the intestinal wall. The primary or idiopathic type represents 15% of cases and is a self-limited or chronic benign entity. The secondary type represents 85% of cases and is associated with various factors, such as surgery, pharmacotherapy, chemotherapy, autoimmune diseases, inflammatory diseases, and pulmonary illness. Pneumatosis cystoides intestinalis affects the colon (pneumatosis cystoides coli) in about half of the cases...

BACKGROUND: Spontaneous pneumoperitoneum (SP) without gastrointestinal perforation rarely occurs in neonates, with most SP cases being idiopathic. Although SP usually follows a benign clinical course with favorable prognosis, it can become life-threatening in certain situations. In these cases, urgent surgical intervention may be required. Therefore, it may be difficult to decide when or how to perform prompt interventions. AIM: To demonstrate the distinct clinical features of SP to guide appropriate management by comparing characteristics between SP and typical pneumoperitoneum secondary to gastrointestinal perforation...

Pneumatosis intestinalis (PI), pneumoperitoneum, and ascites are radiographic findings that may be incidental or associated with severe bowel compromise. Asymptomatic patients with benign PI, pneumoperitoneum, or ascites are often observed or treated conservatively. However, these findings are concerning in symptomatic patients and often require surgical consultation and urgent surgical intervention Approximately 15% of PI cases are idiopathic, and 85% are secondary due to an underlying pathology including but not limited to pulmonary disease, autoimmune disease, drug-induced sources, gastrointestinal disease, infectious sources, and iatrogenic sources...

The most common cause of pneumoperitoneum is perforated hollow viscus, which generally necessitates emergent surgical intervention. Idiopathic spontaneous pneumoperitoneum (ISP) is a rare condition less commonly described. This report outlines the case of a 79-year-old male with recurrent idiopathic spontaneous pneumoperitoneum managed by repeated laparotomy. Knowledge of this rare phenomenon and appropriate workup may allow for the avoidance of unnecessary laparotomies. Despite this, definitively ruling out perforated hollow viscus is difficult outside of the operating room, and many patients will ultimately be taken for surgical exploration and definitive diagnosis...

Intra-abdominal free gas is a finding of extra-intestinal gas in the abdominal cavity on radiography or CT, mainly suggesting gastrointestinal perforation and necessitating emergency surgery. Idiopathic pneumoperitoneum is diagnosed when there is no obvious gastrointestinal perforation, but there is presence of free gas in the abdominal cavity with an unidentifiable cause. Herein, we report a case of idiopathic pneumoperitoneum secondary to high-energy trauma following a car rollover accident. A 95-year-old man was transferred to our clinic after a car-to-car rollover accident...

Idiopathic pneumoperitoneum has an unknown etiology despite exploratory laparotomy. However, it may occur without definite abdominal symptoms; thus, adequate management could be in clinical dilemma. We experienced three cases of idiopathic nonsurgical pneumoperitoneum in healthy individuals during a health check-up. Their cases were not accompanied by any relevant etiology or definite abdominal symptoms. All of the three cases exhibited a benign clinical course. The three patients underwent an abdominal computed tomography (CT) scan as part of a health check-up program, which incidentally revealed free air in the right paracolic gutter without evidence of visceral perforation or inflammation...

A 46-year-old male referred to the Emergency Department with pain in the left flank. The patient suffered from Crohn's disease. He had not experienced any fever, and a urine strip showed signs of blood. A ureteric calculus was suspected and a computed tomography scan was performed, which surprisingly showed free intraperitoneal air (FIA) located along the ascending colon. The patient had no signs indicative of peritonitis and the spontaneous pneumoperitoneum was suspected. Pneumoperitoneum is often associated with severe intraabdominal pathology, such as perforation of the gastrointestinal tract, requiring acute surgical intervention...

We experienced a case of laparoscopic left hemicolectomy for advanced descending colon cancer in patient with idiopathic pulmonary arterial hypertension(IPAH). The patient was a 39-year-old woman. She visited her family doctor in November 201X because of bowel movement disturbance and melena. She was diagnosed as advanced descending colon cancer. Although intraoperative management for hemodynamic stability was expected to be difficult due to IPAH, hemodynamic stability was achieved under 10 mmHg pneumoperitoneum...

We present a 67-year-old gentleman with a high perioperative mortality and morbidity risk who presented with spontaneous idiopathic tension pneumoperitoneum that was successfully managed with bedside pig-tail catheter insertion. Here we also discuss other potential non-surgical aetiologies of pneumoperitoneum.
