da $Vinci^{TM}$ Surgical System is an advanced mode of minimal invasive surgery, using 3-dimensional imaging system and robotic arms which can mimic the dexterity of the human hand. Thus, various operations can be performed with minimal incision and limited surgical field and the merits of minimal invasive surgery can be maximized by using it. We report our first experience of robotic open heart surgery using the da $Vinci^{TM}$ Surgical System for repairing atrial septal defect.

Odontogenic infection in the oral and maxillofacial regions caused by bacteria (mostly of oral origin) is one of the most common diseases encountered by dentists. Localized infection can easily be treated with incision and drainage followed by antibiotics. Emergence of multidrug resistant (MDR) bacteria called "Superbacteria" has become one of the serious problems in modern society, due to its small window of opportunity for treatment and high casualty. The acronym "ESKAPE", encompassing the common and serious MDR pathogens stand for Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp. Literature search was performed in Medline, PubMed and Google Scholar ranging from 2012 to 2020. ESKAPE patient's infection period was longer than that of non-ESKAPE group, and the treatment method due to antibiotic resistance was also complicated. The purpose of this study is to investigate infection caused by ESKAPE pathogens in the oral and maxillofacial regions through literature review and to inform dental surgeons of the danger of ESKAPE pathogens and to suggest viable treatment options. Many studies worldwide reported infections associated with ESKAPE pathogens, but only limited number of studies targeted infection in oral and maxillofacial regions. Further research is required with more data on ESKAPE bacteria and their infection, especially in oral and maxillofacial regions.
Although laparoscopic pancreaticoduodenectomy (LPD) is considered as minimally invasive surgery, an advanced level of laparoscopic skill is still required. LPD comprises various procedures including reconstruction. Therefore, establishment of a safe approach at each step is needed. Prevention of intraoperative bleeding is the most important factor in safe completion of LPD. The establishment of effective retraction methods is also important at each site to prevent vascular injury. I also recommend the "uncinate process first" approach during initial cases of LPD, in which the branches of the inferior pancreaticoduodenal artery are dissected first, at points where they enter the uncinate process. This approach is performed at the left side of the superior mesenteric artery (SMA) before isolating the pancreatic head from the right aspect of the SMA, which allows safe dissection without bleeding. Safe and reliable reconstruction is also important to prevent postoperative complications. Laparoscopic pancreatojejunostomy requires highly skilled suturing technique. Pancreatojejunostomy through a small abdominal incision, as in hybrid-LPD, facilitates reconstruction. In LPD, the surgical view is limited. Therefore, we must carefully verify the position of the pancreaticobiliary limb. A twisted mesentery may cause severe congestion of the pancreaticobiliary limb following reconstruction, resulting in severe complications. We must secure the appropriate position of the pancreaticobiliary limb before starting reconstruction. We describe the incidence of intraoperative and postoperative complications and appropriate technique for safe performance of LPD.

Although posterolateral thoracotomy(PLT) has been a standard thoracic incision in resection surgery of the lung for surgeons to achieve a good surgical field, there remains concern about severing a group of thoracic muscles remains. Muscle-sparing vertical thoracotomy (MVT) is an alternative to PLT, which gives cosmetic result and may preserve motion of the shoulder girdle as well as respiratory function of the patient in the early postoperative period. However, surgeons tend not to perfer it because of limited surgical field from the vertical wound made on the lateral thoracic wall. The purpose of this study is to compare the surgical outcomes of PLT versus MVT. We retrospectively reviewed 29 patients(15 who had PLT and 14 who had MVT, organized into those two groups) who had undergone lung resection surgery in our institute. There were no clinical differences between the two groups in terms of operation time, estimated amount of blood loss during the operation, amount of chest drainage on the first and the second postoperative day, duration of chest tube placement, incidence and amount of transfusion, and postoperative complications. We conclude that, from our limited experience, MVT can be applied to lung resection surgery as safely as PLT and that it may have a beneficial role for the patient with compromised lung function in addition to cosmetic effect.
Purpose: Endoscopic incision and submucosal dissection (EISD) is a technique that is being implemented for the resection of gastric adenomas and early gastric cancer (EGC). Since EISD requires a high degree of skill and experience, and due to its association with a moderate risk of gastrointestinal bleeding, its use has been limited. The objective of this study is to investigate the clinical benefits of EISD based upon clinical data on the EISD procedure. Materials and Methods: This study was conducted at Soonchunhyang University Hospital and it included 179 gastric adenoma and early gastric carcinoma lesions from 164 patients who had undergone an EISD from February 2003 to May 2005. Results: Among the total of 179 lesions, the distributions of EGC and adenomas were 70.3% (126/179) and 23.4% (42/179) respectively. The sizes of lesions were divided into 10 mm or less, $11{\sim}20\;mm,\;21{\sim}30\;mm$ and greater than 31 mm and each rates are 10.0% (18/179), 46.3% (83/179), 30% (50/179) and 15.0% (28/179). Among 120 cases which could be measured depth of lesion in according to pathologic findings, m1 (0.8%, 1/120), m2 (38.3%, 46/120), m3 (25%, 57/120), sm1 (11.7%, 14/120), sm2 (1.6%, 2/120) were diagnosed as early stages of gastric cancer. The complete resection rate was 85.2% (150/176) and en-bloc resection rate was 96.0% (169/176). Complications as such as perforation and bleeding developed in 4.4%(8/179) and 21.2% (38/179), respectively. Conclusion: EISD is an effective in the endoscopic treatment for gastric adenoma and early gastric cancers. However, further evaluation of this method and long-term follow-up will be necessary for an evaluation of the recurrence rate after resection of a tumor.
Endoscopic transthoracic sympathectomy (ETS) has recently become estabilished as a successful treatment for severe palmar and axillary hyperhidrosis. Descriptions have been published of neurolytic, operative and alternative endoscopic procedures involving thermocoagulation, laser coagulation, or or nonvideo-assisted ganglionectomy using equipment not widely available, with low morbidity and excellent results. All methods have advantage and disadvantages. A 19-year-old male who suffered from severe hyperhidrosis on face, palms and axillary areas, has been initially treated with stellate ganglion block in other pain clinic. He was transfered to our pain clinic for endoscopic thoracic sympathectomy. The patient was intubated left side 34 Fr. double lumen tube and positioned left semi-lateral position for right sympathectomy. Right side pneumothorax was created by clamping the ipsilateral side of the double lumen tube and aspiration of air. 11-mm trocar was introduced through incision at the third intercostal space in anterior axillary line, and then additional two 11-mm and 5-mm trocar was introduced through second and fifth intercostal space in mid axillary line. The lung was gently retracted and the parietal pleura over the heads of the appropriate ribs excised using 5-mm sharp insulated coagulating microprocesss. The T4, T3, and T2 ganglions, as well as accompanying rami communicantes, and other branchs arising from upper thoracic nerves to the brachial plexus and surrounding tissues were carefully dissected, coagulated. During sympathectomy, skin temperature of middle was continuously monitored. Elevation of palmar skin temperature intraoperatively indicated an adequate sympathectomy with a definite therapeutic effect. A No. 28 Fr. thoracotomy tube was introduced through a troca under video guidance, placed under water seal after the lung was reinflated. the controlateral side was performed same procedure. After bilateral sympathectomy, chest tubes were removed, and then, he was discharged 2 days after operation with great satisfaction. The ETS provides a well-tolerated, cost-effective alternative to thoracic sympathectomy for primary hyperhidrosis and sympathetic mediated neuropathic pain disorder. And T2 ganglion is considered the key ganglion for the treatment of primary hyperhidrosis. The low incidence of compensatory sweating may by explained by the limited extent of the sympathectomy.
Purpose: Reduction by simply assembling bones is recognized as treatment for a zygoma fracture. However, in patients who originally had a protruding zygoma, the fractured parts look like malarplasty after the edema subsides, giving a soft impression which patients notice. Thus, we created symmetry through simultaneous contralateral malar reduction in a unilateral zygoma fracture. Methods: In this study, the patients who had surgery between July, 2008 and December, 2009 with admission were object. In 76 patients with a zygoma fracture, the patients with bilateral zygoma fractures were excluded. Among 48 patients who had a reduction only after a unilateral zygoma fracture, the patients hoping for a reduction of their rough protruding zygoma were analyzed with front cephalometry. The study progressed on 22 patients who had simultaneous contralateral malar reduction in a unilateral zygoma fracture with consent. After fixing the fracture, we did a straight zygoma osteotomy through a 1.5 cm intraoral incision. After that, we created symmetry with a special ruler and fixed the broken zygomatic arch with a screw and plate. We evaluated the facial index and satisfaction with a statistical analysis before and after the surgery. Results: In 22 patients, there was no reoperation except for 1 patient who had a zygoma fracture. None of the patients were treated for infection or hematoma. Two patients complained of paresthesia after the malar reduction operation, but this subsided in 4 months. Most of them were satisfied with the malar reduction, especially the women, and we obtained a better mid facial contour with decreased facial width ($p$ <0.05). Conclusion: Existing zygoma fracture surgery focuses on anatomical reduction. However, we need to have a cosmetic viewpoint in fractures as interests of face contour arise. Thus, contralateral malar reduction got a 4.7 (range 0~5) from patients who had malar reduction surgery in our hospital. Although adjusting to all zygoma fractures has limitations, it can be a new method in zygoma fractures when there are limited indications of protruding zygoma and careful attention is given to patients' high demands.
Avulsion fractures of the intercondylar eminence of the tibia are not uncommon. In the displaced avulsion fracture, anatomical reduction and firm fixation of fracture fragments are needed but the most of the conventional operative techniques including arthroscopic technique are relatively complex and need. The results were not always satisfactory due to the risk of postoperative complications such as wound infection, premature epiphyseal closure and loss of fixation after early motion etc. So we describe a simple and safe modified method of arthroscopic reduction and fixation for avulsion fractures of the intercondylar eminence of the tibia. In our thirteen cases, we achieved anatomical reduction and secure fixation using cannulated screw through the three arthroscopic portals (anterolateral, medial mid-patellar and central). Postoperatively, immediate limited range of motion of the knee and partial weight bearing were possible. Additional use of the washer afforded safe fixation of comminuted avulsion fracture. The advantage of this technique includes its technical simplicity, easy removal of hardware, ability to treat comminuted type IV fracture with washer, no additional skin incision, no damage to growing plate in growth children and less morbidity.

Hypertrophic cardiomyopathy is characterized by inappropriate hypertrophy of the myocardium and is associated with various clinical presentations ranging from complete absence of symptoms to sudden, unexpected death. These are caused by dynamic obstruction of the left ventricular outflow tract and surgical approaches were initiated. But, the complete resection of hypertrophied midventricular septum is impossible by standard, transaortic approach, because of narrow vision and limited approach. And it leads to inadequate excision, will leave residual left ventricular out-flow tract obstruction or systolic anterior motion of mitral leaflet, and limit symptomatic improvement and patient's survival. We report a case of extended septal myectomy for hypertrophic cardiomyopathy of mid-septum in a child. The extended septal myectomy was performed by aortotomy and left ventricular apical incision, and made possible the complete resection of mid-ventricular septum, abnormal papillary muscles and chordae. The patient's symptom was improved and the postoperative course was uneventful.

Background: This study aims to evaluate whether or not the method of right vertical axillary minithoracotomy (RVAM) is preferable to and as reliable as conventional sternotomy surgery, and also assesses its cosmetic results. Methods: Thirty-three patients (7 males, 26 females) with atrial septal defect were admitted to the Cardiovascular Surgery Clinic of Cukurova University from December 2005 until January 2010. The patients' ages ranged from 3 to 22. Patients who underwent vertical axillary minithracotomy were assigned to group I, and those undergoing conventional sternotomy, to group II. Group I and group II were compared with regard to the preoperative, perioperative and postoperative variables. Group I included 12 females and 4 males with an average age of $16.5{\pm}9.7$. Group II comprised 14 female and 3 male patients with an average age of $18.5{\pm}9.8$ showing similar features and pathologies. The cases were in Class I-II according to the New York Heart Association (NYHA) Classification, and patients with other cardiac and systemic problems were not included in the study. The ratio of the systemic blood flow to the pulmonary blood flow (Qp/Qs) was $1.8{\pm}0.2$. The average pulmonary artery pressure was $35{\pm}10$ mmHg. Following the diagnosis, performing elective surgery was planned. Results: No significant difference was detected in the average time of the patients' extraportal circulation, cross-clamp and surgery (p>0.05). In the early postoperative period of the cases, the duration of mechanical ventilator support, the drainage volume in the first 24 hours, and the hospitalization time in the intensive care unit were similar (p>0.05). Postoperative pains were evaluated together with narcotic analgesics taken intravenously or orally. While 7 cases (43.7%) in group I needed postoperative analgesics, 12 cases (70.6%) in group II needed them. No mortality or major morbidity has occurred in the patients. The incision style and sizes in all of the patients undergoing RVAM were preserved as they were at the beginning. Furthermore, the patients of group I were mobilized more quickly than the patients of group II. The patients of group I were quite pleased with the psychological and cosmetic results. No residual defects have been found in the early postoperative period and after the end of the follow-up periods. All of the patients achieved functional capacity per NYHA. No deformation of breast growth has been detected during 18 months of follow-up for the group I patients, who underwent RVAM. Conclusion: To conclude, the repair of atrial septal defect by RVAM, apart from the limited working zone for the surgeon in these pathologies as compared to sternotomymay be considered in terms of the outcomes, and early and late complications. And this has accounted for less need of analgesics and better cosmetic results in recent years.
