We herein present 2 cases of adult Bochdalek hernia. Only a total of 51 such cases have been reported since 1958, and we have reviewed these cases and discussed their clinical features, operative treatment and final outcome. The majority of these patients presented as acute surgical emergencies and a lack of awareness of this condition lead to an incorrect diagnosis in 38 per cent. Intestinal obstruction with left lung signs and a non-distended abdomen in an adult patient should arouse suspicion of this condition. A plain X-ray of the chest and contrast studies of the gastrointestinal tract are necessary to confirm the diagnosis. A previous normal chest X-ray does not rule out a diaphragmatic hernia, as the defect may be plugged by the spleen or by the presence of a confining sac. The high incidence of strangulation emphasises the need for early diagnosis and prompt operative management which gives highly satisfactory results.

Adult Bochdalek hernia--clinical features, management and results of treatment.

Bochdalek hernias are a very rare form of diaphragmatic hernias. There are no robust studies that reveal the true natural history of this disease process. The aim of this study was to summarize clinically relevant data for the purpose of assisting surgeons with the work-up, diagnosis, and treatment of adult patients with Bochdalek hernia. A literature search was performed using PubMed, Google scholar, EMBASE and the following keywords: Bochdalek hernia, congenital diaphragmatic hernia, and posterolateral hernia. All case reports and series after 1955 that pertained to adults were included in the review. The following data points were queried: age, sex, presentation, studies utilized during work-up, laterality, surgical approach, hernia sac management, specific minimally invasive surgical techniques, and follow-up. A total of 124 articles comprising 173 patients met the inclusion criteria. Based on the data provided, several conclusions regarding this disease process can be made. Most patients present with symptoms related to their hernia (86%). Pain is the most common complaint (69%). While laparotomy is the most widely used surgical approach (38%), minimally invasive surgical techniques have gained popularity since their first report in 1995. Laparoscopic repair can be performed with a low complication rate (7%) and short hospital stay (4 days). Using modern surgical techniques to include laparoscopy, repair can be performed safely, with a short hospital stay, and with minimal morbidity or mortality.

Bochdalek hernia in the adult: demographics, presentation, and surgical management

Congenital diaphragmatic hernia is rarely seen in adults. A review of the literature is presented, and 2 additional cases of Morgagni and Bochdalek hernias are presented. They were both repaired with the laparoscopic approach.
