Tension Pneumoperitoneum

Needle Decompression of Tension Pneumoperitoneum: A Case Report

Introduction

Tension pneumoperitoneum is rarely encountered in the emergency department but can have disastrous effects on the body when it is. However, an emergency physician has skills that can be readily applied to needle decompress the abdomen for rapid stabilization.

Case Report

A 42-year-old male arrived via ambulance after a likely overdose with mental status improvement following naloxone administration. He was found to be in respiratory distress due to a rigid, distended abdomen that required intubation for stabilization. Computed tomography imaging showed significant pneumoperitoneum with tension physiology. Surgery consultation was unable to intervene immediately, and needle decompression with an angiocatheter was performed at the bedside with immediate ventilatory improvement.

Conclusion

Tension pneumoperitoneum is a rare but potentially disastrous consequence of overdose secondary to emesis and rupture of the gastric wall. Needle decompression is a skillset already in the emergency physician’s toolbox and can be applied for emergency stabilization of a tension pneumoperitoneum with proper forethought and technique.

Diagnosis and management of iatrogenic endoscopic perforations: European Society of Gastrointestinal Endoscopy (ESGE) Position Statement - Update 2020

1:  ESGE recommends that each center implements a written policy regarding the management of iatrogenic perforations, including the definition of procedures that carry a higher risk of this complication. This policy should be shared with the radiologists and surgeons at each center. 2 : ESGE recommends that in the case of an endoscopically identified perforation, the endoscopist reports its size and location, with an image, and statement of the endoscopic treatment that has been applied. 3:  ESGE recommends that symptoms or signs suggestive of iatrogenic perforation after an endoscopic procedure should be rapidly and carefully evaluated and documented with a computed tomography (CT) scan. 4 : ESGE recommends that endoscopic closure should be considered depending on the type of the iatrogenic perforation, its size, and the endoscopist expertise available at the center. Switch to carbon dioxide (CO2) endoscopic insufflation, diversion of digestive luminal content, and decompression of tension pneumoperitoneum or pneumothorax should also be performed. 5 : ESGE recommends that after endoscopic closure of an iatrogenic perforation, further management should be based on the estimated success of the endoscopic closure and on the general clinical condition of the patient. In the case of no or failed endoscopic closure of an iatrogenic perforation, and in patients whose clinical condition is deteriorating, hospitalization and surgical consultation are recommended.

Tension pneumoperitoneum: Case report of a rare form of acute abdominal compartment syndrome

•

Pneumoperitoneum is a rare cause of ACS.

•

A defined approach has not been established.

•

Whenever possible a minimally invasive approach should be attempted.

•

Avoiding laparotomy may benefit certain patients.

•

Reports are important in order to establish a treatment protocol.

Introduction: Tension pneumoperitoneum is a severe and rare form of pneumoperitoneum with concomitant hemodynamic instability and respiratory failure. It is a variant of abdominal compartment syndrome (ACS) causing an abrupt increase in intra-abdominal pressure.

Presentation of case: We present a case of pneumoperitoneum, after an endoscopic mucosal resection with the development of ACS. The patient was successfully treated with percutaneous decompression.

Discussion: Decompressive laparotomy is the first treatment option for both most forms of pneumoperitoneum and ACS; nevertheless, this issue is controversial. Recent reports have shown that some patients may be candidates for a minimally invasive catheter decompression avoiding major decompressive surgery. Identifying these patients is vital to avoiding unnecessary surgeries.

Conclusions: Tension pneumoperitoneum is a life-threatening event, early detection and intervention is critical in order to provide prompt and optimal treatment approaches.

The Endoscopic Treatment of Iatrogenic Gastrointestinal Perforation

BACKGROUND

Iatrogenic gastrointestinal perforation is a life-threatening complication that arises very rarely in routine endoscopic procedures, with an incidence of 0.03-0.8%. It is more likely in highly complex and invasive therapeutic interventions. In certain situations, endoscopic closure of the perforation and treatment with antibiotics can obviate the need for emergency surgical repair.

METHODS

This review is based on pertinent articles retrieved by a selective literature search in PubMed and on a relevant position paper.

RESULTS

Existing clinical studies of treatment for iatrogenic gastrointestinal perforation are mainly retrospective and uncontrolled. No randomized and controlled trials have been performed to date. If the perforation is discovered soon after it arises, endoscopic treatment can be considered. Gastrointestinal perforations that are less than 30 mm in size can be closed with a clip. In the esophagus, expanding metal stents can be used as well. Clip application is successful in 80-100% of cases of gastrointestinal perforation, and the perforation remains permanently closed in 60-100% of cases. Reports on the endoscopic treatment of esophageal perforation show mixed results, with closure rates of roughly 90% and clinical success rates of roughly 80%. If endoscopic treatment is not possible, timely laparoscopic or open surgical repair is needed.

CONCLUSION

The endoscopic treatment of iatrogenic perforations is safe and reliable. Success depends on early detection, adequate endoscopic closure with properly mastered technique, and the early initiation of concomitant antibiotic treatment, which must be continued for a full course. Most patients who are treated in this way do not need emergency surgery.

Tension pneumoperitoneum: a rare complication of upper gastrointestinal endoscopy

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 department because of melena. Esophagogastroscopy was unsuccessful because of failure to inflate the stomach, and sudden abdominal distension was noted immediately after the procedure. The hemodynamic status of the patient was compromised, and the imminent collapse was prevented with emergent needle paracentesis. Decompression of the abdominal cavity restored vital signs to normal allowing definitive surgical treatment.

DISCUSSION

Upper gastrointestinal endoscopy is a rare cause of this life-threatening complication. The combination of acute abdominal distension with hemodynamic instability following endoscopic procedures should raise suspicion of tension pneumoperitoneum. Needle decompression is life-saving and should be performed instantly upon recognition of this condition.

Tension pneumoperitoneum during routine colonoscopy

Colonoscopy is generally a safe and effective means to detect, diagnose, and treat colonic abnormalities. Although the overall complication rate is low, the morbidity and mortality following perforation approach 50%. Here we present a case of a 49-year-old woman undergoing routine colonoscopy when she suffered bowel perforation and tension pneumoperitoneum. This is a seldom occurrence and may result following bowel perforation with the rapid accumulation of free air into the peritoneal cavity. It is a life-threatening complication and a surgical emergency.
