Infantile hepatic hemangioma, the most common vascular tumor of the liver in infancy, can occur with acute postnatal liver and congestive heart failure. Nevertheless, its course is often benign, and many children can be diagnosed and treated without surgical intervention. The distinction from malignant diseases is not always easy and it not clear whether invasive procedures for diagnosis and therapy should be performed. Here we report our experiences in our Center for Pediatric Liver Disease and postulate that large studies are needed to avoid unnecessary invasive procedures for these patients in the future.

The senses that a doctor can feel is limited in MIS(Minimal Invasive Surgery) which guarantees the fast recovery of the patient and minimal incision for going in and out of instruments through the tissue of the patient. In particular, the surgical robotic teleoperation system developed recently serves with only the information of eyesight and auditory sense. Therefore force-reflection is the most demanded element of the senses in manipulating surgical instruments. In this paper, we designed the Master system and the 2 D.O.F grasper for the robotic teleoperation system(Slave) that has two force sensors on the grasper. Particularly, we focused on serve to master's handle with the contact force between tissue and the grasper of Slave.

Recently, the incidence of Achilles tendon rupture has been increasing with an increase in the elderly and the sports population. Various kinds of surgical options have been introduced up to now. Among them, the traditional open repair is most commonly used despite the risk of re-rupture or post-operative infections, which in turn can impair the blood flow to the Achilles tendon. Therefore, minimally invasive methods to overcome these complications have been studied with excellent outcomes.

국균은 사람에서 발견되는 진균중 가장 흔한 것이기는 하나 낮은 병원성을 갖고 있다. 국균의 호흡기 감염은 국균종, 기관지폐 국균증,괴사성 및 침습형 폐 국균증의 유형으로 분류된다. 이중 괴사성 및 침습형 폐 국균증은 장기 이식 후 면역억제 치료를 받고 있거나, 항암요법을 받는 자, 혈액 이상자 또는 후천성 면역 결핍증 환자 같이 면역 저하자에서 주로 발생하며 정상적인 면역 능력이 있는 자에서는 발병률이 매우 낮다. 본원에서는 정상 면역 능력을 갖은 자에서 흉추에 침범한 침습형 페 국균증을 1예 치험하였기에 보고하는 바이다.

Various minimally invasive repair techniques have been performed for acute Achilles tendon rupture. Despite this, it is difficult to use these techniques in common practice because of the necessity of special instruments. We propose a novel minimal invasive technique using sponge holding forceps, which are commonly used in the operating room for the acute Achilles tendon rupture.

Chronic invasive fungal sinusitis (CIFS) is a relatively rare disease which occurs in immunocompetent or immunocompromised patients. We report a case of CIFS in ethmoid sinus with concurrent fungal ball in maxillary sinus. After surgical debridement and antifungal therapy, CIFS recurred with submucosal invasion in nasopharynx and osteomyelitis of clivus. Although CIFS encompasses a slowly progressing invasive fungal disease but potentially aggressive. It should be noted that CIFS could progress and extend through submucosal route without evidence of mucosal lesion.

Klebsiella pneumoniae is known to cause an invasive syndrome characterized by primary liver abscess associated with metastatic infection. The characteristics of the metastatic infection involving the musculoskeletal system in this invasive syndrome are not well understood. The authors present a case report of a patient who developed abscesses of the lower extremities along with abscesses of multiple organs, such as the liver and eye, caused by K. pneumoniae. The patient was diagnosed early, and the infection was successfully controlled after several surgical treatments.

Aim: To take a deeper insight into the relationship between the root of the inferior mesenteric artery (IMA) and the autonomic nerve plexuses around it by cadaveric anatomy and explore anatomical evidence of autonomic nerve preservation in high ligation of the IMA in laparoscopic surgery for colorectal cancer. Methods: Anatomical dissection was performed on 11 formalin-fixed cadavers and 12 fresh cadavers. Anatomical evidence-based autonomic nerve preservation in high ligation of the IMA was performed in 22 laparoscopic curative resections of colorectal cancer. Results: As the upward continuation of the presacral nerves, the bilateral trunks of SHP had close but different relationships with the root of the IMA. The right trunk of SHP ran relatively far away from the root of IMA. When the apical lymph nodes were dissected close to the root of the IMA along the fascia space in front of the anterior renal fascia, the right trunk of SHP could be kept in suit under the anterior renal fascia. The left descending branches to SHP constituted a natural and constant anatomical landmark of the relationship between the root of IMA and the left autonomic nerves. Proximal to this, the left autonomic nerves surrounded the root of the IMA. Distally, the left trunk of the SHP departed from the root of IMA under the anterior renal fascia. When high ligation of the IMA was performed distal to it, the left trunk of SHP could be preserved. The distance between the left descending branches to SHP and the origin of IMA varied widely from 1.3 cm to 2.3 cm. Conclusions: The divergences of the bilateral autonomic nerve preservation around the root of the IMA may contribute to provide anatomical evidence for more precise evaluation of the optimal position of high ligation of the IMA in the future.

This study evaluated and compared the donor site morbidity following minimally invasive and conventional open harvesting of iliac bone for secondary alveolar bone grafting in cleft palate patients. A thorough electronic search of PubMed, Google Scholar, EMBASE, and an institutional library and manual search of various journals was done; Inclusion criteria: 1) full-text articles using a minimally invasive or conventional open harvesting technique for iliac bone for secondary alveolar grafting in cleft palate patients and 2) articles published between January 1, 2001 and June 30, 2017 and Exclusion criteria: 1) articles published in languages other than English, 2) case reports, case series, animal studies, in vitro studies, and letters to the editor, and 3) full-text article unavailable even after writing to the authors. Preliminary screening of 274 studies excluded 223 studies for not meeting the eligibility criteria. Of the remaining 51 studies, 19 were removed for being duplicates. Of the remaining 32 studies, 15 were excluded after reading the abstract. Of the 17 studies that were left, 2 were excluded because they were in a language other than English, and 2 were excluded because the study group did not mention cleft palate patients. Thus, 13 studies providing results for a total of 654 patients were included in this qualitative synthesis. Minimally invasive bone graft harvest techniques are better than the conventional open iliac bone harvest method because they offer shorter operative time, decreased requirement for pain medications, less pain on discharge, and a shorter hospital stay.

Fungal sinusitis is relatively rare, but it has become more common in recent years. When fungal sinusitis invades the orbit, it can cause proptosis, chemosis, ophthalmoplegia, retroorbital pain, and vision impairment. We present a case of an extensive orbital floor defect due to invasive fungal sinusitis. A 62-year-old man with hypertension and a history of lung adenocarcinoma, presented with right-side facial pain and swelling. On admission, the serum glucose level was 347 mg/dL, and hemoglobin A1c was 11.4%. A computed tomography scan and a Waters' view X-ray showed right maxillary sinusitis with an orbital floor defect. On hospital day 3, functional endoscopic sinus surgery was performed by the otorhinolaryngology team, and an aspergilloma in necrotic inflammatory exudate obtained during exploration. On hospital day 7, orbital floor reconstruction with a Medpor Titan surgical implant was done. In principle, the management of invasive sino-orbital fungal infection often begins with surgical debridement and local irrigation with an antifungal agent. Exceptionally, in this case, debridement and immediate orbital floor reconstruction were performed to prevent enophthalmos caused by the extensive orbital floor defect. The patient underwent orbital floor reconstruction and received intravenous and oral voriconazole. Despite orbital invasion, there were no ophthalmic symptoms or sequelae.
