Objectives: The purpose of this study was to analyze the survival rate of reconstruction plates that were used to correct mandibular discontinuity defects. Materials and Methods: We analyzed clinical and radiological data of 36 patients. Only discontinuous mandibular defect cases were included in the study. Reconstruction plate survival rate was analyzed according to age, gender, location of defect, defect size, and whether the patient underwent a bone graft procedure, coronoidectomy, and/or postoperative radiation therapy (RT). Results: Plate-related complications developed in 8 patients, 7 of which underwent plate removal. No significant differences were found in plate survival rate according to age, gender, location of defect, defect size, or whether a bone graft procedure was performed. However, there were differences in the plate survival rate that depended on whether the patient underwent coronoidectomy or postoperative RT. In the early stages ($9.25{\pm}5.10months$), plate fracture was the most common complication, but in the later stages ($35.75{\pm}17.00months$), screw loosening was the most common complication. Conclusion: It is important to establish the time-related risk of complications such as plate fracture or screw loosening. Coronoidectomy should be considered in most cases to prevent complications. Postoperative RT can affect the survival rate and hazard rate after a reconstruction plate is fitted.

Purpose: We developed a standardized critical pathway for gastric cancer surgery and then determined the increase of application, which resulted in an improvement in terms of measurable indices, such as hospital stay and cost. Materials and Methods: A critical pathway was revised and used widely from the 2nd quarter of 2009. We collected clinical data, such as length of stay and complication rate, as clinical indices of quality prospectively. The total cost paid at the patient's discharge, as well as the daily hospital income, were calculated and compared by each quarter from January 2008 to December 2009. Results: The application rate of critical pathway was 11.8% and 87.8% in 2008 and 2009, respectively. There were no perioperative deaths. There was no difference in the complication rates between 2008 and 2009 (P=0.45). However, the mean length of stay was significantly different between the 2 years (P<0.05). Although the total cost was not different, the daily hospital income was significantly higher in the latter year (P<0.05). Conclusions: An increase in the application of critical pathway for gastrectomy resulted in significant decreases in length of stay and increases in the daily hospital income without a compromise on the clinical indices.
Purpose: Report of the good results of breast reconstruction using Becker permanent tissue expander that showed a short operation time and a quick post-operation recovery time, little side effects and usually superb aesthetic results without the need for additional incisions or donor site morbidity. The authors, after carrying out breast reconstruction operations using Becker permanent tissue expander on patients with appropriate indications, attempted to analyze several factors such as complication rates and patient satisfaction measurements. Methods: 11 cases of breast reconstruction using Becker expander implants were carried out on a total of 10 patients between March 2000 and February 2003. The patients were followed up at outpatient visit for an average of 6 months. Results: The most common post-operation complication was pain resulting from saline injection into the expanders, complained by 5 patients(50%). rib fractures, skin necrosis, implant removal due to infection, and breast cancer recurrence each occurred in 1 patient (9.9%). There was no occurrence of skin contracture complications which occurs frequently in case of silicone implant insertion. Patient complacency was surveyed by patient interviews made right after the operations and during outpatient follow-up periods: 5(50%) patients out of 10 showed excellent, 3(30%) good, and 2(20%) showed fair, leaving no patients who were disappointed with operation results. On routine follow-up, 80% of patients expressed satisfaction with the cosmetic outcome of their post-mastectomy beast reconstruction. Conclusion: Breast reconstruction using the Becker expander is a reliable alternative to other reconstructive methods but good patient selection is essential for satisfactory results.
The use of the Angell-Shiley porcine xenograft cardiac valve was limited in number at Seoul National University Hospital chiefly because of the cessation of supply from the manufacturer, Forty-eight Angell-Shiley valves along with the 5 other mechanical or tissue valves were used in 46 patients during the period from 1977 to 1980, and a total of consecutive cases was studied for their early and long-term clinical results. The operative mortality rate was 4.3%; no death after single and 2 deaths after double valve replacement within 30 days of surgery. The 44 early survivors were followed up for a total of 171.6 patient-years and a mean of 46.8$\pm$31.1 months. Four died during the follow-up period with a linealized late mortality rate of 2.33%/patient-year. Four patients had experienced 5 episodes of thromboembolism and one died; a linealized incidence of 2.91% emboli/patient-year. A single case each had a bleeding complication related to the anticoagulants, 0.58% bleeding/patient-year, and prosthetic valve endocarditis, 0.58% endocarditis/patient-year. The clinical improvement was excellent by 70% of the survivors having no cardiac symptoms at the end of the follow-up. The actuarial survival rates were 89.9$\pm$4.9% at 5 years and 69.2$\pm$15.0% at 9 years after surgery. The probabilities of freedom from thromboembolic complication were 92.3$\pm$5.5% and 80.9$\pm$9.0% at 5 and 9 years after surgery. And, the probability of freedom from overall valve failure was 83.4$\pm$6.3% at 5 years and it declined sharply down to 55.9$\pm$22.2% at 9th year of the follow-up. These results are comparable with those in the major reports, except a more accelerated and time-related increases in valve failure after 5 or 6 years after operation with the Angell-Shiley valve. The durability of the xenograft tissue valve remains as the most important debate and the need of more durable tissue valves was also discussed.
Background: Completion thyroidectomy is defined as the surgical removal of the remnant thyroid tissue following procedures less than total or near-total thyroidectomy. Although some authors advocate subtotal thyroidectomy with lower complication rates, total or completion thyroidectomy have been defended by others because of the improved survival and lower morbidity that is comparable with subtotal thyroidectomy. Objectives: The purpose of this paper is to review the necessity and safety of completion thyroidectomy for differentiated thyroid carcinoma(DTC). Materials & Methods: During the past 10 years(1986 to 1996) , authors have performed 211 total thyroidectomy. Ten of these patients were treated by completion thyroidectomy for DTC. Initial operation of 7 patients had been performed at St. Vincents Hospital and 3 patients at other hospital. The medical records of patients undergoing completion thyroidectomy were retrospectively reviewed. Results: The completion thyroidectomy specimen contained residual tumor cells in 8 of the 8 patients with papillary carcinoma and none of the two patients with follicular carcinoma. Complications of completion thyroidectomy were transient hypoparathyroidism in two patients and transient unilateral recurrent laryngeal nerve palsy in one patient. But permanent complications were not noticed. Conclusion: We recommend completion thyroidectomy as an efficient and safe method of surgical treatment with a low complication rate for DTC.
Background and Objectives : Necortizing fasciitis in the cervical region is a very rare disease with high mortality and morbidity rates. The purpose of this study was to analyze the clinical characteristics, treatment results, complication and prognosis of necrotizing fasciitis patients. Materials and Methods : We retrospectively reviewed the inpatient charts treated for cervical necrotizing fasciitis at our Otorhinolaryngology clinic. We diagnosed necrotizing fasciitis by the clinical findings such as swelling, redness and pain of infected area and necrosis of subcutaneous fat layer and fascia observed during surgery. Twenty such patients were identified and treated from January 2011 to December 2016. Results : 20 adults consisting of 14 male and 6 females with cervical necrotizing fasciitis were diagnosed and treated. The most commonly known associated preceding illness were dental abscess and tonsillitis. The most pathogen was Streptococcus species (12/20), followed by Klebsiella pneumonia (6/20), Staphylococcus species (2/20). The mean duration of hospitalization was 32.2 days (range,14-86). The mean Modified Laboroatory Risk Indicator for Necrotizing Fasciitis (M-LRINEC) score is 7.4 and more than 4 points was eighteen. All patients received parenteral antibiotics and surgical drainage after admission. Conclusions : The reason for the high survival rate in the study was the early diagnosis, as well as the early surgical procedure and antibiotics. After the operation, frequent betadine irrigation could improve the patient's condition and recover without severe complication.

Purpose: The aim of this study was to analyze the efficacy and to estimate the complication rate of incontinence surgery according to the surgeon's specialty and whether a preoperative urodynamic study (UDS) was performed, using a nationally representative dataset. Methods: We enrolled 356,155 women over 20 years old who had undergone surgery for stress urinary incontinence between 2006 and 2015. Patients were followed for up to 3 years to analyze the reoperation and complication rates. Data were obtained from the National Health Claims Database of the National Health Insurance Service (NHIS) of Korea. Multiple Cox regression analysis was conducted to examine the efficacy and safety of incontinence surgery according to the surgeon's specialty and whether a preoperative UDS was performed. Results: The hazard ratio (HR) for reoperation was significantly higher for procedures performed by nonurologists than for procedures performed by urologists (HR, 1.174; 95% confidence interval [CI], 1.103-1.249). Acute urinary retention, postoperative infections, procedure-associated pain, and other complications were also more common in procedures performed by nonurologists than in those performed by urologists. When stratified by whether a preoperative UDS was performed, the HR for reoperation according to the surgeon's specialty varied by performance of a preoperative UDS. While the reoperation rate was significantly higher in procedures performed by non-urologists when a preoperative UDS was performed (HR, 1.208; 95% CI, 1.122-1.3), there was no significant difference in the HRs for reoperation according to specialty when a preoperative UDS was not performed. Conclusions: This population-based study showed that the postoperative outcomes of incontinence surgery were dependent upon the surgeon's specialty and that the reoperation rate according to the surgeon's specialty varied based on whether a preoperative UDS was performed.
Purpose: Transcatheter device closure of patent ductus arteriosus (PDA) is challenging in early infancy. We evaluated PDA closure in infants less than 6 months old. Methods: We performed a retrospective review of infants less than 6 months of age who underwent attempted transcatheter device closure in our institution since 2004. To compare clinical outcomes between age groups, infants aged 6-12 months in the same study period were reviewed. Results: A total of 22 patients underwent transcatheter PDA closure during the study period. Patient mean age was $3.3{\pm}1.5months$, and weight was $5.7{\pm}1.3kg$. The duct diameter at the narrowest point was $3.0{\pm}0.8mm$ as measured by angiography. The most common duct type was C in the Krichenko classification. Procedural success was achieved in 19 patients (86.3%). Major complications occurred in 5 patients (22.7%), including device embolization (n=1), acquired aortic coarctation (n=2), access-related vascular injury requiring surgery (n=1), and acute deterioration requiring intubation during the procedure (n=1). Two patients had minor complications (9.1%). Twenty-four infants aged 6-12 months received transcatheter device closure. The procedural success rate was 100%, and there were no major complications. The major complication rate was significantly higher in the group less than 6 months of age (P=0.045). There was a trend toward increased major complication and procedural failure rates in the younger age group (P<0.01). Conclusion: A relatively higher incidence of major complications was observed in infants less than 6 months of age. The decision regarding treatment modality should be individualized.

Background: Distal biceps rupture is a relatively uncommon injury that can significantly affect quality of life. Early complications following biceps tendon repair are not well described in the literature. This study utilizes a national surgical database to determine the incidence of and predictors for short-term complications following distal biceps tendon repair. Methods: The American College of Surgeons' National Surgical Quality Improvement Program database was used to identify patients undergoing distal biceps repair between January 1, 2011, and December 31, 2017. Patient demographic variables of sex, age, body mass index, American Society of Anesthesiologists class, functional status, and several comorbidities were collected for each patient, along with 30-day postoperative complications. Binary logistic regression was used to calculate risk ratios for these complications using patient predictor variables. Results: Early postoperative surgical complications (0.5%)-which were mostly infections (0.4%)-and medical complications (0.3%) were rare. A readmission risk factor was diabetes (risk ratio [RR], 4.238; 95% confidence interval [CI], 1.180-15.218). Non-home discharge risk factors were smoking (RR, 3.006; 95% CI, 1.123-8.044) and ≥60 years of age (RR, 4.150; 95% CI, 1.611-10.686). Maleness was protective for medical complications (RR, 0.024; 95% CI, 0.005-0.126). Surgical complication risk factors were obese class II (RR, 4.120; 95% CI, 1.123-15.120), chronic obstructive pulmonary disease (COPD; RR, 21.981; 95% CI, 3.719-129.924), and inpatient surgery (RR, 8.606; 95% CI, 2.266-32.689). Conclusions: Complication rates after distal biceps repair are low. Various patient demographics, medical comorbidities, and surgical factors were all predictive of short-term complications.
Background/Aims: Endoscopic ultrasound gallbladder drainage (EUS-GBD) is gaining attention as a treatment method for cholecystitis. However, only a few studies have assessed the outcomes of permanent stenting with EUS-GBD. Therefore, we evaluated the clinical outcomes of permanent stenting using EUS-GBD. Methods: This was a retrospective, single-center cohort study. The criteria for EUS-GBD at our institution are a high risk for surgery, inability to perform surgery owing to poor performance status, and inability to obtain consent for emergency surgery. EUS-GBD was performed using a 7-Fr double-pigtail plastic stent with a dilating device. The primary outcomes were the recurrence-free rate of cholecystitis and the late-stage complication-avoidance rate. Secondary outcomes were technical success, clinical success, and procedural adverse events. Results: A total of 41 patients were included in the analysis. The median follow-up period was 168 (range, 10-1,238) days. The recurrence-free and late-stage complication-avoidance rates during the follow-up period were 95% (38 cases) and 90% (36 cases), respectively. There were only two cases of cholecystitis recurrence during the study period. Conclusions: EUS-GBD using double-pigtail plastic stent was safe and effective with few complications, even in the long term, in patients with acute cholecystitis.
