ABSTRACT
Objective To analyze the clinical efficacy of non-inflatable transaxillary approach and transthoracic approach surgery for thyroid cancer,and analyze the occurrence of postoperative complications in patients.Methods The clinical data of 88 patients with thyroid cancer who underwent surgical treatment in our hospital from October 2019 to November 2022 were analyzed.They were divided into group A and B according to the surgical method.Forty-five patients in group A received complete endoscopic thyroidectomy through the non-inflatable axillary approach,while 43 patients in group B received endoscopic thyroidectomy through the thoracic approach.The perioperative indicators,satisfaction with surgical incision,postoperative pain,and incidence of complications of patients in the two groups were compared.And the main influence factors for the occurrence of complications were analyzed.Results The total satisfaction rate for surgical incision of patients in group A was significantly higher than that in group B(P<0.05);while the intraoperative bleeding volume and postoperative drainage volume of patients in group A were significantly lower than those in group B(P<0.05).The VAS score 3 and 5 days after surgery were significantly lower than that 1 day after surgery(P<0.05),and the VAS score 5 days after surgery was lower than that 3 days after surgery(P<0.05).The incidence of postoperative complications in group A was significantly lower than that in group B(P<0.05).Logistic regression results showed that intraoperative bleeding volume was the independent influencing factor for postoperative complications(P<0.05).Conclusion Both non-inflatable transaxillary approach and transthoracic approach surgery are effective for thyroid cancer,but the non-inflatable transaxillary approach surgery has the advantages of concealed incision,higher postoperative aesthetics,and less intraoperative bleeding volume,postoperative drainage volume and postoperative complications.Excessive intraoperative bleeding is the main factor leading to postoperative complications.
ABSTRACT
Objective To study the clinical value of transection of Glissonean sheath for laparoscopic anatomic liver resections. Methods The patients of liver resections using laparoscopic Glissonean sheath-transection anatomy technology were 20 cases with liver lesions including 12 cases of primary liver cancer, 4 cases of intrahepatic bile duct stones, 2 cases of liver hemangioma,1 case of focal nodular hyperplasia of the liver (FNH) and 1 case of hepatocellular adenomas (HCAs). Results Surgical procedures included segment Ⅱ, Ⅲ,Ⅳ in 6 cases, segmentⅡ, Ⅲ in 5 cases, segmentⅤ, Ⅵ, Ⅶ, Ⅷ in 3 case, segmentⅤin 1 case, segment Ⅵ in 2 cases, segment Ⅵ, Ⅶ in 3 cases. Mean operation time is (144.77 ± 24.68) min. The mean blood loss in operation is (279.00 ± 132.70) ml. The mean postoperative hospital stay is (8.22 ± 1.40) d. Biliary fistula occurred in 1 case, subphrenic infection occurred in 1 case,and it was cured with medical therapy. No postoperative complications such as bleeding occurred. Conclusion Based on these preliminary results, we conclude that laparoscopic Glissonean sheath-transection technology for liver resection can be well applied in laparoscopic liver segment resection above liver resection avoiding problems such as instant bleeding and manipulation of ducts, can be carried out safely and effectively by experienced laparoscopists in selected cases, of whose liver lesions were located in left liver lobe and some segments of right liver lobe.
ABSTRACT
In this paper, a syntactic pattern recognition method of the detection of pulse wave's characteristic information is introduced. According to it, the pressure signal of pulse is measured by non-invasive diagnostic method. Then, the elementary abstracting system transfers it into an input pattern. The recognizer, constructed by Earley algorithm, recognizes the pulse wave's pattern. On the base of it, the pulse wave's characteristic information can be got. Thus, the expert system will make a diagnosis with the information. The experiment result shows that, the new method is of anti-interference, preciseness and intelligence, and it provides an advanced, practical and intelligent means for the pulse diagnostic system.
