Isolated pneumomediastinum following laparoscopic cholecystectomy: a rare complication

Symptomatic Pneumomediastinum Following Laparoscopic Cholecystectomy: A Case Report and a Literature Review

Isolated pneumomediastinum is a rare complication after laparoscopic procedures. Herein, we present a case of a 38-year-old woman who presented two days after laparoscopic cholecystectomy with pleuritic chest pain and dyspnea and was found to have isolated pneumomediastinum. The patient was admitted for monitoring, oxygen therapy, and antibiotic prophylaxis and she was discharged on the fourth postoperative day when her symptoms resolved both subjectively and radiologically. Only two other cases of symptomatic isolated pneumomediastinum after laparoscopic cholecystectomy were reported in the literature and all of them were female patients, diagnosed radiologically, and treated conservatively. Therefore, isolated pneumomediastinum should be included in the differential diagnosis of dyspnea and chest pain after laparoscopic surgeries in order to have an early diagnosis, start early treatment, and prevent unnecessary investigations or advancement of the disease.

Pneumomediastinum and ECG changes during laparoscopic Nissen fundoplication in a child; Case report

INTRODUCTION

Laparoscopic surgeries are becoming more popular in many surgical procedures particularly in pediatric age group. The physical responses and hemodynamic changes that occur during laparoscopic surgery differ between adults and pediatrics.

CASE PRESENTATION

We report a sudden hemodynamic instability and abrupt ECG changes associated with pneumomediastinum (PM) during laparoscopic Nissen fundoplication surgery in a 19 months old boy who had gastro-esophageal reflux disease. Procedure was converted to open surgery and all parameters were spontaneously returned back to normal values. The patient was successfully extubated then transferred to intensive care unit (ICU) for close monitoring. He had uneventful post-operative course where PM has been completely resolved in the repeated chest x-ray.

DISCUSSION

Pneumomediastinum (PM) occurs when air escape into the mediastinum. This air might reach the pericardium causing hemodynamic and electrophysiological changes. It is one of the reported complications that might occur during laparoscopic surgery, however isolated PM usually resolve spontaneously without any intervention. Etiology and possible contributing factors were discussed.

CONCLUSION

Pneumoperitonium leads to different hemodynamic changes during laparoscopic surgery in pediatric population compared to adults. Decreasing the insufflation pressure and patient's re-positioning might make continuing laparoscopy safe. However, surgeon must be willing to convert to open surgery to prevent any further complications.
