Traumatic tricuspid regurgitation is a rare complication of blunt chest trauma caused by chordal rupture, anterior papillary muscle rupture and anterior leaflet tear. Since clinical symptoms are vague, early diagnosis is difficult and some patient exhibit symptoms of right heart failure. Right heart failure has been the traditional indication for surgical treatment, such as tricuspid valve replacement. Recently, early detection using transthoracic echocardiography and surgical treatment, like valve repair, prior to overt right heart failure have been shown to better prognosis. We report a case of traumatic tricuspid regurgitation with chordal rupture in patient due to traffic accident.

Cornelia de Lange syndrome (CdLS) is a rare multisystemic disorder that is characterized by mental retardation, prenatal and postnatal growth retardation, limb anomalies, and distinctive facial features, which include arched eyebrows that often meet in the middle (synophrys), long eyelashes, low-set ears, small and widely spaced teeth, and a small and upturned nose. Ophthalmic manifestations include long eyelashes, nasolacrimal duct obstruction, myopia, ptosis, and strabismus. There has been no report of surgical treatment for esotropia and unilateral ptosis in patients with CdLS in Korea. I report a patient with CdLS who underwent surgical treatment for esotropia and unilateral ptosis with a good surgical outcome.

Rapid adoption of a robotic approach as a minimally invasive surgery tool has enabled surgeons to perform more complex hepatobiliary surgeries than conventional laparoscopic surgery. Although various types of liver resections have been performed robotically, parenchymal transection is challenging as commonly used instruments (Cavitron Ultrasonic Surgical Aspirator [CUSA] and Harmonic) lack articulation. Further, CUSA also requires a patient-side assistant surgeon with hepatobiliary laparoscopic skills. We present a case report of total robotic right hepatectomy for multifocal hepatocellular carcinoma in a 70-year-old male using 'Vessel Sealer' for parenchymal transection. Total operative time was 520 minutes with a blood loss of ~400 mL. There was no technical difficulty or instrument failure encountered during surgery. The patient was discharged on postoperative day five without any significant complications such as bile leak. Thus, Vessel Sealer, a fully articulating instrument intended to seal vessels and tissues up to 7 mm, can be a promising tool for parenchymal transection in a robotic surgery.

Purpose: This study was done to evaluate the experience of securing patient safety in hospital operating rooms. Methods: Experiential data were collected from 15 operating room nurses through in-depth interviews. The main question was "Could you describe your experience with patient safety in the operating room?". Qualitative data from the field and transcribed notes were analyzed using Strauss and Corbin's grounded theory methodology. Results: The core category of experience with patient safety in the operating room was 'trying to maintain principles of patient safety during high-risk surgical procedures'. The participants used two interactional strategies: 'attempt continuous improvement', 'immersion in operation with sharing issues of patient safety'. Conclusion: The results indicate that the important factors for ensuring the safety of patients in the operating room are manpower, education, and a system for patient safety. Successful and safe surgery requires communication, teamwork and recognition of the importance of patient safety by the surgical team.

As expectations for medical service have increased recently, the interest in medical quality improvement and patient safety has increased. In addition, as part of efforts to improve the training environment of the residents, the working hours of the residents are reduced which means that the medical workforce is expected to change significantly in the future. As a result, in hospital care of surgical patients, it is inevitable to change the patient care system by surgeon-residents to the new system. For this, the introduction of a surgical hospitalist system is proposed as an alternative. This article is an introduction to the process of introducing a surgical hospitalist system in a single institution and describes in detail the considerations This is the first case of the introduction of surgical hospitalist in Korea. Through this case, we intend to lay the groundwork for the successful implementation of the surgical hospitalist in Korea.

52 cases of ventricular septal defect [VSD] associated with aortic insufficiency [Al] were found among 1271 patients with simple VSD operated during 27-year period [1959, August-1987, June] at Seoul National University Hospital. Their preoperative data, intraoperative findings and postoperative short-term and long-term follow-up data were evaluated to find the proper timing and method of surgical treatment. The result of this survey shows as follows: 1. To obtain the proper surgical indication, cardiac catheterization and angiography, especially root aortography, was essential. 2. Of all 52 patients, the VSD were type I in 40 patients [77%], type II in 8 [15%] and combination of type I and II in 4 [3%]. Patch closure of VSD were performed in 46 patients and direct suture closure of small VSD in 6. Most common pathologic findings of Al were prolapse of right coronary cusp [40 cases, 77%]. Aortic valve reconstruction were performed in 19 patients, aortic valve replacement in 6 and VSD closure alone in 27. 3. There were 3 surgical deaths [mortality 5.8%], and the long-term follow-up shows that VSD closure alone might have been sufficient to arrest progression of Al in younger patients [less than 10-year old], particularly in those with mild insufficiency. Valve reconstructions, when necessary, were more effective when done at an early age [less than 15-year old]. In a conclusion, we could recommend followings: 1. If patient at any age having VSD with Al is diagnosed, prompt operation is recommended. As for the surgical method, VSD closure only may be fit for mild degree of Al when patient is less than 10-year old, but the management of valve itself may be needed for moderate to severe degree of Al, especially when patient is over 10 year old. The management of valve itself may be variable, but valve reconstruction should be considered as a first choice in less than 15-year old patient. If patient is diagnosed less than 5-year old without evidence of Al, close follow-up observation is recommended. But if Al evidences of clinical findings and/or echocardiography during follow-up examination are notified, corrective operation should be accomplished while the Al is mild. If cusp prolapse and/or even type I VSD of significant size is demonstrated on aortogram, without Al, it should be corrected as early as possible before the patient is about 5 years old.

Objective : The aim of this study to investigate the benefits of patient-based 3-dimensional (3D) cerebral arteriovenous malformation (AVM) models for preoperative surgical planning and education. Methods : Fifteen patients were operated on for AVMs between 2015 and 2019 with patient-based 3D models. Ten patients' preoperative cranial angiogram screenings were evaluated preoperatively or perioperatively via patient-based 3D models. Two patients needed emergent surgical intervention; their models were solely designed based on their AVMs and used during the operation. However, the other patients who underwent elective surgery had the modeling starting from the skull base. These models were used both preoperatively and perioperatively. The benefits of patients arising from treatment with these models were evaluated via patient files and radiological data. Results : Fifteen patients (10 males and five females) between 16 and 66 years underwent surgery. The mean age of the patients was 40.0±14.72. The most frequent symptom patients observed were headaches. Four patients had intracranial bleeding; the symptom of admission was a loss of consciousness. Two patients (13.3%) belonged to Spetzler-Martin (SM) grade I, four (26.7%) belonged to SM grade II, eight (53.3%) belonged to SM grade III, and one (6.7%) belonged to SM grade IV. The mean operation duration was 3.44±0.47 hours. Three patients (20%) developed transient neurologic deficits postoperatively, whereas three other patients died (20%). Conclusion : Several technological innovations have emerged in recent years to reduce undesired outcomes and support the surgical team. For example, 3D models have been employed in various surgical procedures in the last decade. The routine usage of patient-based 3D models will not only support better surgical planning and practice, but it will also be useful in educating assistants and explaining the situation to the patient as well.

Background: Miescher's cheilitis granulomatosa (MCG) is a rare chronic inflammatory disease and is known as the monosymptomatic clinical form of Melkersson-Rosenthal syndrome (MRS). It is characterised by swelling of one or both lips and more frequently affects the upper lip. Histopathological findings show the presence of numerous inflammatory infiltrates and granuloma formations. Pharmacological treatments and surgery have provided results that are positive yet insufficiently stable in the long term. The clinical case described is of a 68-year-old female patient with a diagnosis of MCG of the upper lip. Case presentation: The patient was diagnosed and treated at the Oral Medicine and Oral Pathology outpatient clinic of Maxillofacial and Odontostomatology Unit, Fondazione Cà Granda IRCCS Ospedale Maggiore Policlinico. The patient was recommended localised treatments of photobiomodulation (PBM) using a diode laser with a 635 nm and 980 nm dual-wavelength (λ) approach, a 600-micron fibre, and a handpiece with a 1-cm-diameter lens at 300 mW. Three treatments a week were administered for four weeks for a total of 12 treatment sessions (T₁-T₁₂). After that, the patient had a long follow-up period of about 2 years. The therapeutic results were clear from the initial stages of treatment. There was an immediate, gradual, and consistent reduction in labial swelling. A reduction in the size of the lip by about 35% at T₁₀-T₁₂ was observed, returning the size and volume of the upper lip within the normal clinical range. The painful symptoms subsided after the seventh treatment (T₇). The histopathological check at 3 months and the follow-up in particular confirmed the disease was in remission with satisfactorily stable treatment results. Moreover, the patient did not use any other treatments on the area from the early laser treatments through to the end of the follow-up period. Conclusions: Our experience describes a clinical case of MCG treated with PBM and effectively resolved with a reduction of the lip swelling. The real success of the treatment emerged over time, showing that the tissue healing was stable. In absence of any collateral phenomena, this confirms the effective and documented therapeutic potential of PBM for chronic inflammatory infiltrates.

Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore, laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologic findings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph node metastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, the diagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymph node metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful in determining the primary origin of lymph node metastasis.

Patient safety has become a growing concern in health care. The U.S. Institute of Medicine (IOM) report "To Err Is Human: Building a Safer Health System" in 1999 included estimations that medical error is the eighth leading cause of death in the United States and results in up to 100,000 deaths annually. However, many adverse events and errors occur in surgical practice. Within all kinds of surgical adverse events, wrong-side/wrong-site, wrong-procedure, and wrong-patient adverse events are the most devastating, unacceptable, and often result in litigation. Much literature claims that systems must be put in place to render it essentially impossible or at least extremely difficult for human error to cause harm to patients. Hence, this research aims to develop a prototype system based on active RFID that detects and prevents errors in the OR. To fully comprehend the operating room (OR) process, multiple rounds of on site discussions were conducted. IDEF0 models were subsequently constructed for identifying the opportunity of improvement and performing before-after analysis. Based on the analysis, the architecture of the proposed RFID-based OR system was developed. An on-site survey conducted subsequently for better understanding the hardware requirement will then be illustrated. Finally, an RFID-enhanced system based on both the proposed architecture and test results was developed for gaining better control and improving the safety level of the surgical operations.
