We report the case of an adult patient recently diagnosed with cirrhosis. The ultrasound evaluation described a multinodular inhomogeneous liver, requiring a magnetic resonance imaging scan for further characterization. The performed magnetic resonance imaging examination confirmed the diagnosis of cirrhosis associated with portal hypertension and detected a vascular left transdiaphragmatic hernia. Although various types of diaphragmatic hernias have been described - congenital or acquired - to the best of our knowledge, this type of pathology has never been reported.

Iatrogenic right diaphragmatic hernia is very rare. We report the first case of a patient who had a diaphragmatic hernia after laparoscopic fenestration of liver cyst. A herniorrhaphy of the diaphragmatic defect was carried out after reducing the herniated organ. The postoperative course was uneventful. Diaphragmatic hernias are not as common as the traumatic type. Surgeons can easily miss diaphragmatic injuries during the operation especially after laparoscopy. Late diagnosis of iatrogenic diaphragmatic hernias is frequent. Ct scan is helpful for diagnosis. Surgery is the treatment of diaphragmatic hernia at the time of diagnosis, even with asymptomatic patients. The incidence of iatrogenic diaphragmatic hernia after surgery may be reduced if the surgeon checks for the integrity of the diaphragm before the end of the operation. A review of the literature is also performed regarding this rare complication.

Bochdalek hernia is the most common type of congenital diaphragmatic hernia. It appears frequently in infants but rarely in adults. We present the case of a 50-year-old female han patient with tremendous left-sided congenital posterolateral diaphragmatic hernia (Bochdalek hernia) who also has a pair of supernumerary breasts and pulmonary hypoplasia of the lower-left lobe. The patient had an experience of misdiagnosis and she was treated for bronchitis for one year until being admitted to our hospital. This case study emphasizes the rare presentation of Bochdalek hernia in adults and the necessity of high clinical attention to similar cases.

Iatrogenic diaphragmatic hernias are a rarely reported complication of abdominal surgery. We present a case of an iatrogenic diaphragmatic hernia diagnosed 2 years after an adrenalectomy. Corrective laparoscopic surgery was performed, and the postoperative course was uneventful. The patient remained asymptomatic 6 months after the repair. To our knowledge, this is the first such case to be reported.

Abstract Background: Recurrent herniation is a well-known complication following the initial repair of congenital diaphragmatic hernias (CDHs). The role of minimally invasive surgical techniques in recurrent CDH remains undefined. The purpose of this study was to evaluate our early experience with thoracoscopic repair compared with traditional open repair in children with recurrent CDH. Subjects and Methods: We retrospectively reviewed all recurrent Bochdalek CDH cases (n=24) managed at a single tertiary-care referral center between January 1990 and March 2011. Children who underwent thoracoscopic repair for recurrent CDH were identified, and their data were compared by the unpaired t test and the two-sided Fisher’s exact test, as appropriate, with those of children who underwent open repair. Significance was defined as P<.05. Results: Thoracoscopic repair was attempted in 6 (25%) children with recurrent CDH. Four (67%) repairs were successfully completed without conversion to an open procedure. The mean age at thoracoscopic repair was 11.5 months (range, 8.1-16.1 months). The mean operative time was 191 minutes (range, 94-296 minutes), and all children were extubated within 24 hours. The mean hospital length of stay was 3.75 days (range, 1-6 days). There were no deaths or subsequent recurrences after a mean follow-up of 26.5 months (range, 14.3-41.3 months). There were no statistical differences in any of the measured outcome variables when compared with the open repair group. Conclusions: Our initial experience suggests that thoracoscopic repair is a feasible alternative to open repair in selected children with recurrent Bochdalek diaphragmatic hernias.

Objective:To analyze operative repair, extracorporeal membrane oxygenation (ECMO) and survival rates based on highest pre-ductal oxygen saturation (Pre-O(2)SAT) in a large infant cohort reported to Congenital Diaphragmatic Hernia Study Group Registry between 2000 and 2010.Study Design:Analyzed data included gestational age, birth weight, defect side and size, repair, ECMO use, survival and highest reported PaO(2) and Pre-O(2)SAT in first 24 h of life. We excluded 614 infants due to severe anomaly. Pre-O(2)SAT data were available for 1672 infants.Result:Among infants with highest Pre-O(2)SAT value <85%, survival (24/105=23%) and repair (55/105=52%) rates were significantly decreased compared with infants with higher values. Survival increased to 44% for infants with highest Pre-O(2)SAT<85% who underwent operative repair. Of these, 83% (20/24) required ECMO support compared with 15% (144/961) of survivors with Pre-O(2)SAT>99% (P<0.001). The lowest reported Pre-O(2)SAT with survival was 32% and for survival without ECMO was 52%.Conclusion:A reported highest Pre-O(2)SAT<85% in the first 24 h of life was not uniformly fatal; but survival of infants with Pre-O(2)SAT<85% was associated with high ECMO use and prolonged hospitalization.

Background: There is no consensus or evidence as to whether a neuromuscular blocking agent should be used during the initial resuscitation of infants with congenital diaphragmatic hernia (CDH) in the labour ward. Objective: To determine if administration of a neuromuscular blocking agent affected the lung function of infants with CDH during their initial resuscitation in the labour ward. Methods: Fifteen infants with CDH were studied (median gestational age 38 weeks, range 34-41; birth weight 2,790 g, range 1,780-3,976). Six infants had undergone feto-endotracheal occlusion (FETO). Flow, airway pressure, tidal volume and dynamic lung compliance changes were recorded using a respiratory function monitor (NM3, Respironics). Twenty inflations immediately before, immediately after and 5 min after administration of a neuromuscular blocking agent (pancuronium bromide) were analysed. Results: The median dynamic lung compliance of the 15 infants was 0.22 ml/cm H(2)O/kg (range 0.1-0.4) before and 0.16 ml/cm H(2)O/kg (range 0.1-0.3) immediately after pancuronium bromide administration (p < 0.001) and remained at a similar low level 5 min after pancuronium bromide administration. The FETO compared to the non-FETO infants had a lower median dynamic compliance both before (p < 0.0001) and 5 min after pancuronium administration (p < 0.001) and required significantly longer durations of ventilation (p = 0.004), supplementary oxygen (p = 0.003) and hospitalisation (p = 0.007). Conclusions: Infants with CDH, particularly those who have undergone FETO, have a low lung compliance at birth, and this is further reduced by administration of a neuromuscular blocking agent.
