Morgagni hernia: transabdominal or transthoracic approach?

BACKGROUND

Morgagni hernias are rare and constitute less than 2% of all diaphragmatic hernias. Treatment is primarily surgical and transthoracic or transabdominal route approach methods are amenable. In this study, we compared the results of our Morgagni hernia cases, which underwent either transabdominal or transthoracic method of surgery.

METHODS

We retrospectively analyzed the records of 20 patients we operated on for Morgagni hernias between 1997 and 2011 in our clinic. Age, sex, presenting symptoms, lesion location, diagnoses, applied surgical method, duration of the hospital stay, morbidity and mortality rates were reviewed. Six of the cases were (30%) approached via thoracotomy and 14 (70%) were laparotomy. The hernial sac was resected in all cases. Diaphragmatic defects were repaired using nonabsorbable sutures in all cases except in one case where prolen mesh used.

RESULTS

Thirteen cases (65%) were female and seven (35%) were male. Mean age was 44.1 +/- 25.3 years (1-73 years). Hernias were located on the right side in 18 cases, the left side in one, and bilaterally located in one case. Herniated organs were: omentum in 19 (95%), transverse colon in 18 (90%), small bowel in 4 (20%), stomach in 3 (15%), and left lobe of the liver in one (5%) case. No complication was observed in patients who underwent laparotomy, and wound infection occurred in one patient who underwent thoracotomy. Hospital stays in thoracotomy and laparotomy groups are 7 and 6.2 days, respectively. There were no mortalities observed. There was no recurrence during the follow-up of 36.4 months (10-116 months).

CONCLUSION

Our findings showed that both surgical methods have similar and satisfactory results. Although transthoracic approach was preferred in previous cases, the transabdominal approach was preferred in later ones because we assumed that the later procedure is less invasive for the patient. We prefer and propose the abdominal approach for the surgical management of Morgagni hernias.

Mutation analysis in patients of Mediterranean descent with Wilson disease: identification of 19 novel mutations

In this study, we report further results of mutation analysis of the ATP7B gene in Wilson disease (WD) patients of Mediterranean origin. A total of 136 WD chromosomes, 73 of which were of Italian, 43 of Turkish, 18 of Sardinian, and two of Spanish origin, were analysed and the mutation characterised in 84.5% of them. We found 50 different mutations of which 19 are novel, including three nonsense, one frameshift, and 15 missense mutations. The mutations detected were rare and mostly found in the compound heterozygous state together with other mutations and only rarely in homozygosity. Most of these mutations lie in the transmembrane and ATP binding loop regions. These data expand our knowledge of both the structure-function relationships of the WD protein and the molecular pathology of WD, thus improving our capability of prevention and genetic counselling.

Left ventricular dysfunction due to hypocalcemia in a neonate

Hypocalcemia is a relatively uncommon but reversible cause of left ventricular dysfunction in infants and children. A 30-day-old boy with idiopathic hypocalcemia presented with congestive heart failure and convulsive seizures. He had no evidence of underlying cardiac disease. The cardiac failure responded to calcium therapy. It is suggested that hypocalcemia should be considered as a possible cause of left ventricular dysfunction in infants.
