Lateral esophagostomy: an alternative in the initial management of long gap esophageal atresia without fistula.

The authors report an alternative method of cervical esophagostomy that was used in a child with type A esophageal atresia. This method involved performing a lateral esophagostomy in the proximal pouch, preserving its distal end, allowing the child to swallow normally, without choking, while stimulating the spontaneous growth of the proximal esophagus. As a result, the infant could be discharged home on G-tube feedings while waiting for spontaneous growth of the proximal pouch to occur. There were no episodes of aspiration during this period, and definitive reconstruction through end-to-end esophageal anastomosis was accomplished successfully at the age of 18 months. The authors consider that this alternative might increase the possibility of a definitive correction through delayed primary anastomosis of the infant's own esophagus in children with this type of malformation.

Trigeminal neuralgia treated by percutaneous thermocoagulation. Comparative analysis of percutaneous thermocoagulation and other surgical procedures.

The authors analyze the results they obtained by percutaneous radiofrequency technique for trigeminal neuralgia. The clinical material consists of 605 cases observed from 1977 to 1986 at their Institute. There was a female preponderance (62%) and an average age of 65 years. Idiopathic, atypical and symptomatic trigeminal neuralgia has been diagnosed respectively in 568, 21 and 16 cases. From 1977 to 1980 the working temperature was above 65 C, thereafter a lower temperature has been employed to coagulate the Gasserian ganglion. The rate of pain relief was 97% for idiopathic trigeminal neuralgia, 75% for symptomatic and 21% for atypical. The loss of facial sensation accounts for 80% of side effects of this procedure in their series. The recurrence of pain was observed in 16% of cases with a follow-up ranging from 2 to 10 years. It is noteworthy that there is a correlation between the coagulation temperature and the rate of recurrence, the higher the former, the lower the latter. The authors compare their results (rate of pain relief, morbidity, mortality, rate of recurrence) with those of major reports in the literature concerning either percutaneous or other surgical procedures (mircosurgical decompression of the trigeminal nerve, glycerol injection into the trigeminal cistern and percutaneous microcompression).
