Objective To research the clinical safety and feasibility of self-made devices in gasless laparoscopic surgery. Methods A total of 5 generations of gasless laparoscopic devices (8 models) were designed and manufactured by ourselves from April 1993 to September 2004. After animal experiments, 15 types of different gasless laparoscopic operations were carried out in 87 patients. Results Out of the 87 cases, conversions to open surgery were required in 7 cases (conversion rate, 8.0%). The other 80 cases of gasless laparoscopic operations were successfully performed, involving cholecystectomy, colorectal resection, partial cecectomy, subtotal gastrectomy, inguinal herniorrhaphy, abdominal wall contraction, radical resection for carcinoma of renal pelvis, haital herniorrhaphy with Toupet’s fundoplication and total hysterectomy. Conclusions Our self-made gasless laparoscopic devices may be applied safely and effectively in clinical cases. Gasless laparoscopic surgery has been reflecting the complementary advantages of modern laparoscopic surgery and traditional open surgery. It is of supplementary significance in patients contraindicated to pneumoperitoneum and of distinctive importance for laparoscopic gastrointestinal surgery requiring abdominal fistulization or prolonged incision, as well as hand-assisted hepatobiliary or pancreatic laparoscopic surgery.

To furtherly reduce the subxiphoid port site pain,improve the cosmetic result and patient satisfaction,and increase the safety for patients underwent laparoscopic cholecystectomy by advanced laparoscopic knotting skill.Methods:Among our 1500 patients underwent laparoscopic cholecystectomy since 1991,120 cases of modified laparoscopic cholecystectomy (MLC) were performed with three 5-mm ports and one 10-mm port(for laparoscope and sepcien withdrawn).There were 25 male and 95 female patients with an average age of 55 years (24～77years).The indications for MLC included polypoid lesions of gallbladder (21),simple cholecystitis(3),cholecystolithiasisi with chronic cholecystitis(84),with acute suppurative cholecystitis(7),with atrophic cholecystitis(5).Results:There were 5 patients underwent combined laparoscopic appendectomy(3),fenestration of hepatic cyst(1),and drainge for liver abscess(1).The average operative time for MLC was 55 minutes(30～150min),blood loss was 10ml(3～50ml),and postoperative stay was 3 days(1～5days).There were no conversion from MLC to either LC or open surgery,without mortality.Complications were limited to two patients(1.7%).One was retained common bile duct stone and another was port site bleeding after operation.They were treated by transduodenal endoscopic stone retrieval and simple suture ligation,respecrtively.Conclusions:The advantages of MLC conducted mainly by advanced laparoscopic knotting techniques were no more laparoscope (either 2-mm or 5-mm)needed,no sacrifice of good illumination and laproscopic image.Most of all,its costeffective and operative safety were all improved furtherly.

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.
