Abstract Background: Whether using the scalpel can provide better and faster recovery after the primary total knee arthroplasty (TKA) is still controversial. The aim of this research was to compare the clinical outcomes of using the scalpel and the electric cautery in primary TKA.Methods: From January 2016 to December 2017, a retrospective cohort study was conducted in 313 patients who underwent unilateral primary TKA by using the scalpel (group S). During this period, we selected 313 patients who underwent unilateral primary TKA by using the electric cautery (group E) for comparison. The tourniquet time, operative time, blood loss, wound complications, visual analog score for pain, range of motion, Knee Society Score were assessed between the two groups. The Forgotten Joint Score was used to analyze the ability to forget the joint. Results: There were no significant differences in tourniquet time, operative time, blood loss between the two groups (p > 0.05). In the group S, the visual analog score for pain, range of motion, Knee Society Score were found better results at 1 week, 1 month, 3 months, 6 months, 12 months and 24 months after surgery (p < 0.05). Besides, during the follow-up period, the Forgotten Joint Score was significantly higher compared with group E (p < 0.05).Conclusion: In this research, the patients who underwent TKA by using the scalpel could achieve better clinical outcomes. In addition, if forgotten artificial joint after TKA was the final goal, the patients who underwent TKA by using the scalpel would acquire better quality of life.

This study describes a novel technique for skeletonization and isolation of Glissonean and venous branches during liver surgery using a harmonic scalpel (HS). Hepatic resections with HS were performed with the skeletonization and isolation technique in 50 patients (HS group). Variables evaluated were blood loss, operative time, biliary leak, and morbidity. The results were compared with 50 hepatic resections that were performed using a previously established technique: Cavitron ultrasonic surgical aspirator with electric cautery, ligatures, and hemoclips (NHS group). The HS group had shorter total operative times (285 versus 358 minutes; P = 0.01), less blood loss (389 versus 871 mL; P = 0.034), and less crystalloid infusion (2744 versus 3299 mL; P = 0.027) compared with the NHS group. Postoperative liver function and complication rates were similar when comparing the two groups. These data demonstrate that HS is a simple, easy, and effective instrument for the skeletonization and isolation of vessels during liver transection.

469 Background: Laparoscopic liver resection has recently become more common. However, it is difficult to resect laparoscopically the liver tumor located in the posterosuperior segments (IVa, VII and VIII), especillay for patients with liver cirrhosis. Compared to laparoscopy, gaining access to tumors in the dome of the liver may be more easily obtained via thoracoscopy.Therefore, we describe the technique and outcome of a video-assisted thoracoscopic transdiaphragmatic liver resection in patients with a malignant tumor of the liver. Methods: Five female patients underwent video-assisted thoracoscopic transdiaphragmatic partial hepatectomy. The tumors were located at segment VIII in 4 patients and segment VII in 1. Three patients were preoparatively diagnosed with hepatocellular carcinoma, and two were metastatic tumor of the colorectal cancer. Underlying cirrhosis was staged as Child-Pugh B in 2 cases and Child-Pugh A in 1. Thoracoscopic transdiaphragmatic partial hepatic resection was chosen due to the tumor’s location and impaired liver function. The patient was placed in an oblique position with her left side on the table. The ports were placed around the tumor at three levels, the ninth (3cm mini-thoracotomy), the seventh (two ports, 5mm and 12mm), and the fifth (12mm) intercostals spaces. Using thoracoscopic ultrasonography, the portion of the diaphragm located just above the tumor was cut and opened using electric cautery. The partial liver resection was performed using coagulating shears and electric cautery. Results: No conversion to laparotomy occurred. The median blood loss was 200 g (20-500g), and median operating time was 220 min (135-347 min). There were no perioperative deaths, and no patients underwent reoperation. Conclusions: Thoracoscopic hepatic resection can be safely performed in patients with subdiaphragmatic tumors, especially with cirrhosis or previous upper abdominal surgery.

Dermatomyositis (DM) is one of the idiopathic inflammatory myopathies caused by complement-mediated vasculopathy or vasculitis in the muscle. Although the gastrointestinal (GI) mucosa has been reported to be involved as a result of vasculitis or vasculopathy, ulceration in the pharynx is a rare manifestation of DM. A 54-year-old woman complaining of muscle weakness in the extremities, low-grade fever, and dysphagia was diagnosed as having DM. Despite medical treatment with corticosteroids and immunosuppressive agents, her DM progressed rapidly, leading to exacerbation of the dysphagia. About 3 weeks after undergoing tracheostomy as a preventive measure against aspiration, the patient developed intractable respiratory tract hemorrhage. Repeated laryngoendoscopy revealed a bleeding ulceration in the pharynx that required hemostasis with electric cautery under general anesthesia. No bleeding recurred thereafter. Histopathologically, the pharynx exhibited nonspecific inflammatory cell infiltration in the muscle tissue. This rare manifestation may be considered in cases of DM with unexplainable airway bleeding.

PURPOSE: To establish an experimental model of laparoscopic partial nephrectomy (LPN) in rats and to analyze morphological alterations in the renal parenchyma utilizing an electric cautery and harmonic scalpel. METHODS: Forty Wistar rats were used, divided in 2 experiments with 20 rats each: experiment I, LPN was performed with an electric cautery and the rats were subdivided into groups A and B; experiment II, LPN was performed with a harmonic scalpel and they were subdivided into groups C and D. The animals in groups A and C were sacrificed shortly after surgery and the remnant kidney was removed to study the following variables: necroses and degeneration. In groups B and D a laparatomy was performed for retrieval of the remnant kidney on the 14th day after surgery to analyze fibrous scarring. RESULTS: For the variables necroses and fibrous scarring, the electric cautery creates, on average, greater width than that produced by the harmonic scalpel (p=0.0002 and p=0.0068 respectively). Regarding the variable of degeneration, we found no significant difference between the two types of scalpels (p=0.1267). CONCLUSIONS: LPN in rats is an adequate and feasible experimental model. The electric cautery caused greater damage to remnant renal tissue when compared to harmonic scalpel.
