Purpose: Blunt small bowel injury (SBI) is frequently combined other organ injury. So, clinical outcome and characteristics of SBI are influenced by other combined injuries. Thus, we analyzed isolated SBI patients and studied clinical outcome and characteristics. Methods: Between 2005 and 2010, 36 consecutive patients undergoing laparotomy due to isolated SBI were identified in a retrospectively collected. Database. Clinical outcome and characteristics were analyzed. Results: Laparotomy was performed in 36 patients. Primary repair was performed 17 patients. Segmental resection of small bowel was performed 19 patients. Median time gap from trauma to operation was 9 hours. In 24 hours from trauma, operation was performed 31 patients. Post operative death was 5 patients. Mean hospital stay was 18 days and median hospital stay was 12 days. There were significant differences between operation type and minor complication and hospital stay. And there were significant differences between time gap in 24 hours and minor complication. But, there were no significant between time gap and mortality. Conclusion: Although this study had many limitations, some valuable information was produced. When operation above 24 hours was delayed in SBI, minor complications were significantly increased. Segmental resection of small bowel in SBI were significantly increased minor complications and hospital stay. So, preventive measures for surgical site infection was important to reduce wound complication and hospital stay. Further continuous study and multi-center study were should be performed to improve clinical outcome in SBI.

The authors analyzed retrospectively the 19 patients with mucoepidermoid carcinoma of salivary glands who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from June, 1986 to September, 1998. The results obtained were as follows: 1. There were 4 males(21%) and 15 females(79%). Age distribution was wide and the mean age was 45.2. 2. Of all mucoepidermoid carcinomas of salivary gonads, 4 cases arose in the major salivary glands and 15 cases in the minor salivary glands. The incidence according to the anatomic primary site for minor salivary glands was 8 cases in the palate, 2 cases each arising in the tongue and floor of mouth and 1 case each arising in the mandible, buccal mucosa and the lower lip. 3. In histopathological classification of mucoepidermoid carcinoma, 5 cases were low grade. 9 cases, intermediate grade and 5 cases, high grade. 4. Perineural invasion was observed 40%(2/5) in high grade and 22%(2/9) in the intermediate grade of mucoepidermoid carcinoma. 5. The incidence of cervical lymph node metastasis according to histopathologic grade was 40% (2/5) in high grade and 11%(1/9) in intermediate grade of mucoepidermoid carcinoma. 6. The lung was the commonest site for metastasis comprising 3 cases among 3 cases of distant spread of which 2 cases in high grade and 1 case in intermediate grade of mucoepidermoid carcinoma.

Purpose: Distally based superficial sural artery island flap has some disadvantages such as postoperative flap edema, congestion, and partial necrosis of the flap margin. Venous congestion is an area of considerable concern in distally based superficial sural artery fasciocutaneous flap and is one of the main reasons for failure, particularly when a large flap is needed. However, we could decrease these disadvantages by means of venous superdrainage. Methods: From June of 2006 to June of 2007, a total of two patients with soft tissue defects of lower one third of the leg underwent venous supercharging distally based superficial sural artery island flap transfer. The distal pivot point of this flap was designed at septocutaneous perforator from the peroneal artery of the posterolateral septum, which was 5 cm above the tip of the lateral malleolus. Briefly, this technique is performed by anastomosing the proximal end of the lesser saphenous vein and collateral vein to any vein in the area of the recipient defect site. Results: No venous congestion was noted in any of the two cases. No other recipient or donor-site complications were observed, except for minor wound dehiscence in one case. In 3 to 6 months follow-up, patients had minor complaints about lack of sensation in the lateral dorsal foot. Conclusion: The peroneal artery perforator is predictable and reliable for the design of a distally based superficial sural artery island flap. Elevation of the venous supercharging flap is safe, easy, and less time consuming. In conclusion, the venous supercharging distally based superficial sural artery island flap offers an alterative to free tissue transfer for reconstruction of the lower extremity.

Backgrounds/Aims: Historically, incidence and survival analysis and annual traits for primary liver cancer (LC) has not been investigated in a population-based study in Korea. The purpose of the current study is to determine incidence, survival rate of patients with primary LC in Korea. Methods: We conducted a retrospective cohort study using Korea Central Cancer Registry based on the Korea National Cancer Incidence Database. Statistical analysis including crude rate and age-standadized rate (ASR) of incidence and mortality was performed for LC patients registered with C22 code in International Classification of Diseases, tenth revision from 1999 to 2019. Subgroup analysis was performed for hepatocellular carcinoma (HCC, C22.0) and intrahepatic cholangiocarcinoma (IHCC, C22.1). Results: The crude incidence rate of HCC (21.0 to 22.8 per 100,000) and IHCC (2.3 to 5.6 per 100,000) increased in the observed period from 1999 to 2019. The ASR decreased in HCC (20.7 to 11.9 per 100,000) but remained unchanged in IHCC (2.4 to 2.7 per 100,000). The proportion of HCC patients diagnosed in early stages (localized or regional Surveillance, Epidemiology, and End Results or SEER stage) increased significantly over time. As expected, 5-yeat survival rate of HCC was greatly improved, reaching 42.4% in the period between 2013 and 2019. This trait was more prominent in localized SEER stage. On the other hand, the proportion of IHCC patients diagnosed in localized stage remained unchanged (22.9% between 2013 and 2019), although ASR and 5-year survival rate showed minor improvements. Conclusions: A great improvement in survival rate was observed in patients with newly diagnosed HCCs. It was estimated to be due to an increase in early detection rate. On the contrary, detection rate of an early IHCC was stagnant with a minor improvement in prognosis.

A 4-month-old boy diagnosed with acute myocarditis was treated with extracorporeal membrane oxygenation (ECMO). Follow-up echocardiography eight hours after ECMO revealed intracardiac thrombosis involving all four heart chambers. Because of the high risk of systemic embolization due to a pedunculated thrombus of the aortic valve, we performed an emergency thrombectomy. After the operation, the patient had a minor neurologic sequela of left upper arm hypertonia, which had almost disappeared at the last outpatient clinic two months later. He was diagnosed with a major mutation in MTHFR (methylenetetrahydrofolate reductase), which is related to thrombosis.

Polymethyl-methacrylate(PMMA; Artecoll$^{(R)}$) microspheres suspended 1 : 3 in a 3.5% collagen solution has been used as an injectable implant for long lasting correction of wrinkles and minor skin defects. The patients with mandibular prognathism have increased necessity for nasal augmentation. Usually these patients usually get an additional rhinoplasty after orthognathic surgery. The purpose of this study is to evaluate the result of PMMA injection for nasal ridge augmentation simultaneously with the orthognathic surgery. PMMAs were injected to the nasal dorsum of 13 patients with mandibular prognathism to augment the nasal ridge at the end of the orthognathic surgery. The cephalometric X-ray and clinical facial photograph were taken at 2, 4 and 6 months after operation. Using S-N line, we calculated the change of soft tisuue on the nasal ridge and also investigated the degree of patients satisfaction at 6 months after operation. Most of the patients were satisfied with their nasal ridge height status from moderate to good degree. The average amount of nasal ridge augmentation was $1.4{\pm}0.5$ mm immediately after operation, $1.2{\pm}0.4$ mm at 2 months after operation. The postoperative nasal ridge height seemed to be remained stable after 2 months. Intraoperative PMMA injection is considered to be simple and effective technique which can be used for the minor augmentation of nasal ridge in the orthognathic patients.

Myoepithelioma is a rare benign neoplasm that mostly arises in the major salivary glands and sometimes in the minor salivary glands, which account only for less than 1% of all salivary glands neoplasms. However, its extra-salivary involvement is even rarer and only a few cases of nasal cavity myoepithelioma were reported in the English-language literature so far. In this case report, we present a 40-year-old female with unilateral nasal obstruction diagnosed as myoepithelioma of the nasal septum and treated with endoscopic sinus surgery.

Occipital alopecia after Open Heart Surgery under the Cardiopulmonary bypass is an uncommon minor complication. We had experienced Occipital alopecia in 6 cases after Open Heart Surgery. The cause of the alopecia was transient circulatory disturbance due to pressure effect of the patient`s head and intraoperative hypotension. The prodromal symptoms of the alopecia were erythema, itching, and watery discharge, but some patients showed non-specific symptoms. The common site of the alopecia was right occipital region and the size was 2-4 cm in diameter. The regrowth of the hair was completed at postoperative 3 to 5 months without specific treatment except conservative treatment. Fortunately the postoperative alopecia is a self-limiting condition, and spontaneous regrowth of hair is the rule without other complications.

Calcific tendinitis of the shoulder joint is common disease causing acute pain, mainly involving the supraspinatus or infraspinatus muscle, and less frequently the teres minor or subscapularis muscle. This study reports on the satisfactory arthroscopic removal of calcium deposits as well as infraspinatus and supraspinatus muscle repair without relapse via minimal incision using suture anchors. This was a case of atypically extensive calcific tendinitis involving the infraspinatus muscle, with a bursal side partial rupture of the supraspinatus muscle in a 61-year-old female whose chief complaint was chronic pain of the right shoulder exacerbated by limited movement.
