Objective To investigate the value of laparoscopy combined with esophagogastroscopy in the treatment of achalasia of the cardia. Methods Twenty-five patients with achalasia of the cardia between October 2003 and April 2006 in this department underwent the HellerDor operation under laparoscopy combined with esophagogastroscopy.Results A1l the operations were successfully accomplished.The operating time was 60~240 min(mean,107 min) and the intraoperative blood loss,5~60 ml(mean,22 ml).Intraoperative mucosal perforation was encountered in 4 patients.All the patients got out of bed for activities at 8 hours after operation,with first passage of flatus,removal of the gastric tube,and liquid diet intake at 1~3 days after operation(mean,1.5 days).The esophageal manometry showed the lower esophageal sphincter(LES) pressure had decreased to normal levels at 7 days after operation.The 24-hour ambulatory pH studies showed a high reflex index in 3 patients,but without symptoms.Upper gastrointestinal barium swallow showed the dilated esophagus had a 8~26 mm(mean,18 mm) decrease in diameter at 8 days after operation.The length of postoperative hospitalization was 8~11 days(mean,8.5 days).Follow-up for 1~30 months(mean,5.4 months) in all the patients showed 23 patients were asymptomatic and 2 had intermittent dysphagia.Conclusions Heller-Dor operation under laparoscopy combined with esophagogastroscopy has advantages of precise positioning,little invasion,less pain,and good effects,increasing the quality of operation as well as decreasing the incidence of complications.

Based on the theory of topological structure within the syndrome of tradition Chinese medicine (TCM), the high order multiple dimensions and nonlinear structure of syndrome can be cracked. And the panorama of complex and changeable syndrome can be showed. The dynamic evolving law of sub-sets of syndromes and the changing rule of the main signs and symptoms with the secondary signs and symptoms can be interpreted. Therefore, the evolving law of sub-sets of syndromes and the accurate corresponding law of prescriptions and medicines can be realized. And the scientific connotation of dynamic evolving rule of syndrome can be revealed. Studying on the occurrence regularity of syndrome, the structure characterization of TCM syndrome can be carried out. And the mathematical structure-physical structure-biological structure can be revealed. Along with the mass new specific forms of syn-dromes to be cracked, the simulation data platform of therapeutic methods with prescriptions and medicines of syn-dromes can be built through the simulation technology of computer. Using the clinical data, through the literature of carding and contrast, the scientific connotation of judgment and diagnostic standard of syndromes can be interpreted. The distracting law of syndromes of diseases can also be revealed through the clinical data of syndrome-groups. And the theoretical basis for the formulation of judgments and diagnostic standard of syndromes of diseases which con-forming to the dynamic evolving law of syndromes can be provided. Evaluation on TCM efficacy can be carried, in order to make clear the curative effect evaluation index system of TCM syndrome in multiple dimensions and multi-ple levels for the promotion of the substantially improvement of syndrome differentiation level.
