Laparoscopic Heller myotomy and Dor fundoplication for the treatment of achalasia. Assessment in relation to morphologic type.

BACKGROUND: The significance of laparoscopic Heller myotomy and Dor fundoplication (LHD) for the treatment of achalasia in relation to the severity of the lesion has not been sufficiently assessed. METHODS: Of patients who were diagnosed with achalasia from August 1994 to February 2004, 55 individuals who underwent LHD served as subjects. The therapeutic effects of LHD were assessed in terms of operation time, intraoperative complications, postoperative hospital stay, and symptom improvement in relation to morphologic type (spindle type, Sp; flask type, Fk; and sigmoid type, Sig). Degree of symptomatic improvement was classified into four grades: excellent, good, fair, and poor. RESULTS: Breakdown of morphologic type was as follows: Sp, n = 29; Fk, n = 18; and Sig, n = 8. Excluding one patient for whom conversion to open surgery was required, median average operation time for 54 patients was 160 min. As to intraoperative complications, esophageal mucosal perforation was seen in nine of the 55 patients (16%); however, conversion to open surgery could be avoided by suturing the affected area. Moreover, intraoperative bleeding of at least 100 g was seen in five of the 55 patients (9%), with one Fk patient requiring conversion to open surgery and transfusion. Median postoperative hospital stay was 8 days. Degree of dysphagia relief was excellent in 45 patients (83%), good in eight patients (15%), and fair in one patient (2%). Excellent improvement was obtained in 90%, 88%, and 50% in Sp, Fk, and Sig patients, respectively. Reflux esophagitis was seen in two patients, and was treated with a proton pump inhibitor. CONCLUSIONS: The results of the present study suggest that classification of morphologic type is a useful parameter in predicting postoperative outcome in achalasia. In order to achieve excellent symptomatic relief, surgery for achalasia should be recommended for but not limited to Sp and Fk types.

[Applicability of percutaneous endoscopic gastrostomy for enteral nutrition].

As the structure of social changes, there is new attention given to emerging methods of home medical care. In addition to decreasing daily costs and the number of patients admitted to hospital, a patient can receive treatment at home, on the tatami where he feels comfortable. Is this not the ultimate goal of medicine? As a result of home care, a patient's quality of life can be improved, a great step for medicine. A growing option for home feeding system is administration of HEN (home enteral nutrition). Use of HEN will likely increase in the future, however, many problems associated with prescriptions and administrative systems need to be addressed. In this article, the clinical merits and drawbacks associated with PEG (percutaneous endoscopic gastrostomy), a new approach rapidly gaining acceptance will be examined.
