RESUMO
BACKGROUND: Double pectus bars are sometimes inserted to correct pectus excavatum. Method of double-bar fixation to prevent bar displacement has been rarely reported. We have used quadrangular fixation of the double pectus bars. The objective of this study was to compare results of the quadrangular fixation procedure with those of the classic separate fixation procedure. METHODS: From September 2011 to January 2016, 86 patients underwent Nuss procedure with double-bar insertion. In 44 patients, each bar was fixed separately (group A). In 42 patients, quadrangular fixation of the bars was performed with metal plates (group B). Patient demographics, Haller index (HI), bar displacement index (BDI), and reoperation rate were compared between the two groups. RESULTS: The mean patient age was 17.2 years (range: 3-40 years) in group A and 17.8 years (range: 4-30 years) in group B. There was no significant difference in preoperative or postoperative HIs between the two groups (all p >0.05). Early complication rates were 15.9% in group A and 9.5% in group B (p > 0.05). In group A, three patients underwent surgery to correct bar displacement (6.8% of reoperation rate), whereas there was no corrective surgery in group B. BDIs of the two groups were significantly different (p < 0.01). CONCLUSIONS: When quadrangular fixation was performed with upper and lower pectus bars bilaterally fixed by connecting each bar with plates, bar displacement was prevented more effectively than separate fixation, thus minimizing reoperation.

BACKGROUND: Robotic surgery is known to have several advantages including magnified three-dimensional vision and angulation of the surgical instruments. To evaluate the feasibility and efficiency of robotic lobectomy in the treatment of lung cancer, we analyzed the outcomes of our initial experiences with robotic lobectomy at a single institution in Korea. METHODS: Eighty-seven patients with lung cancer underwent robotic lobectomy (robotic group: 34 patients) and video-assisted thoracic surgery (VATS) lobectomy (VATS group: 53 patients) between 2011 and 2016 at our hospital. The medical records of these patients were retrospectively analyzed. RESULTS: The operation times of the two groups were significantly different (robotic group, 293±74 min; VATS group, 201±62 min; P<0.01). Intraoperative blood loss occurred more in the robotic group than in the VATS group (robotic group, 403±197 mL; VATS group, 298±188 mL; P=0.018). The numbers of lymph nodes dissected in the two groups were significantly different (robotic group, 22±12; VATS group, 14±7; P<0.01). There was no intraoperative mortality in both groups. CONCLUSIONS: Despite the initial difficulties, robotic lobectomy for lung cancer was a safe and feasible procedure with no operative mortality. If operation time and intraoperative blood loss improve as the learning curve progresses, robotic surgery may overcome the limitations of VATS in lung cancer surgery.
RESUMO
INTRODUCTION: Aortic dissection is a very rare but life-threatening condition associated with a high mortality. Unexpected sudden cardiac death due to aortic rupture following laparoscopic appendectomy is very rare and may be difficult to diagnose. However, early diagnosis of aortic dissection is essential for the timely treatment and outcome of aortic dissection. CASE PRESENTATION: A 50-year-old man underwent a laparoscopic appendectomy. Postoperatively, the patient complained of dyspnea and chest pain. In 25âminutes after arrival in the postanesthesia care unit (PACU), the patient was in asystole. Then, he underwent cardiopulmonary resuscitation (CPR) according to advanced cardiac life support (ACLS) protocol using 1âmg of epinephrine, one 200J DC shock for ventricular fibrillation (V-fib). After that, his noninvasive blood pressure (NIBP) was 80/40âmm Hg, pulse rate (PR) was 140âbeats/min, and peripheral oxygen saturation (SpO2) was 84%. His electrocardiogram (ECG) finding was atrial fibrillation (A-fib). After 20âminutes, the patient developed asystole rhythm again and CPR was restarted. He remained severely hypotensive despite vasopressors and died after 5âhours CPR. A forensic autopsy was performed postmoterm and thoracic and abdominal aortic dissection along the root of ascending aorta was present and massive hematoma within right and left thorax was present. CONCLUSION: Acute aortic disease can be difficult to recognize; therefore, diagnosis is sometimes delayed or missed. It is important to recognize the atypical symptoms of aortic dissection and maintain a broad differential diagnosis if patients complained of abdominal pain.
