Purpose: Gastrostomy is commonly used procedures to provide enteral nutrition support for severely handicapped patients. This study aimed to identify and compare outcomes and complications associated with percutaneous endoscopic gastrostomy (PEG) and surgical gastrostomy (SG). Methods: A retrospective chart review of 51 patients who received gastrostomy in a single tertiary hospital from January 2000 to May 2016 was performed. We analyzed the patients and the complications caused by the procedures. Results: Among the 51 patients, 26 had PEG and 25 had SG. Four cases in the SG group had fundoplication for gastroesophageal reflux disease. PEG and SG groups were followed up for an average of 29 months and 44 months. Major complications occurred in 19.2% of patients in the PEG group and 20.0% in the SG group, but significant differences between the groups were not observed. Minor complications occurred in 15.4% of patients in the PEG group and 52.0% in the SG group. Minor complications were significantly lower in the PEG group than in the SG group (p=0.006). The average use of antibiotics in the PEG and SG groups was 6.2 days and 15.7 days (p=0.002). Thirteen patients died of underlying disease but not related to gastrostomy, and only one patient died due to complications associated with general anesthesia. Conclusion: The duration of antibiotics use and incidence of minor complications were significantly lower in the PEG group than those in the SG group. Early PEG could be recommended for nutritional supports.

Background: Anxiety control remains an important concern in dental practice. We evaluated the incidence, nature, and sequelae of complications during and after minor oral surgeries performed under intravenous midazolam and fentanyl sedation using the titration technique. Method: The medical records of patients who had undergone minor oral surgeries under moderate intravenous midazolam and fentanyl sedation at our institution between January 1, 2015 and December 31, 2015 were retrospectively evaluated. Age, sex, body mass index, medical history, American Society of Anesthesiologists (ASA) classification, indications for sedation, amount of sedative used, surgical duration, and recovery time were evaluated for all patients. Results: In total, 107 patients aged 9-84 years were included. ASA class I and class II were observed for 56.1% and 43.9% patients, respectively. Complications associated with sedation occurred in 11 (10.2%) patients. There were no serious adverse events. Oxygen saturation reached 95% during the procedure in six patients; this was successfully managed by stimulating the patients to take a deep breath. Two patients exhibited deep sedation and one exhibited paradoxical excitement. After the procedure, one patient experienced nausea without vomiting and one exhibited a prolonged recovery time. The surgical procedures were completed in all patients. Obesity was found to be significantly associated with sedation-related complications. Conclusion: Our results suggest that complications associated with intravenous midazolam and fentanyl sedation using the titration technique for minor oral surgeries are mostly minor and can be successfully managed with no prolonged sequelae.

Objective : Surgical treatment of posterior inferior cerebellar artery (PICA) aneurysms is challenging due to limited surgical accessibility. Endovascular approach has a benefit of avoiding direct injury to the brainstem or lower cranial nerves. Therefore, it has recently been considered an alternative or primary modality for PICA aneurysms. We retrospectively assessed outcomes following detachable coil embolization of saccular PICA aneurysms. Methods : From February 1997 to December 2007, we performed endovascular procedures to treat 15 patients with 15 PICA aneurysms. Fourteen patients with 14 PICA aneurysms morphology of which was saccular were reviewed retrospectively. Twelve patients had ruptured aneurysms. The aneurysms arose from the PICA origin site (n=12), the PICA lateral medullary segment (n=1), or the PICA tonsilomedullary segment (n=1). Results : Complete aneurysm occlusion was achieved in 10 patients, residual neck in 3, and residual sac in one. Radiological follow-up was performed in 7 patients with mean duration of 34.7 months (range, 1-97 months) and showed stable or complete occlusion in 6 patients. There were no rebleeding or retreatment after endovascular treatment. Thromboembolism was the only procedure-related complication (n=4 ; 28.6%). Asymptomatic PICA infarction occurred in two patients and symptomatic PICA infarction in two elderly patients with poor clinical grade. Of these procedural PICA infarction cases, 1 symptomatic PICA infarction patient developed ventriculitis and septic shock leading to death. The clinical outcome was good in 10 patients (71.4%). Conclusions : In the present study, detachable coil embolization has shown as an efficient modality for PICA saccular aneurysms challenging indications of microsurgery. However, thromboembolic complications should be considered, especially in poor clinical elderly patients with ruptured aneurysms.

Purpose: The Roux en Y method has rarely been performed due to longer operation time and high risk of complication, despite several merits including prevention of bile reflux. We conducted a retrospective review of the result of Roux en Y reconstruction using two circular staplers after subtotal gastrectomy. Materials and Methods: From December 2008 to May 2009, a total of 26 patients underwent Roux en Y reconstruction using two circular staplers after subtotal gastrectomy, and seventy-two patients underwent Billroth-I reconstruction. Roux en Y anastomosis was performed using two circular staplers without hand sewing anastomosis. We compared clinicopathologic features and surgical outcomes between the two groups. All patients underwent gastrofiberscopy between six and twelve months after surgery to compare the bile reflux. Results: No significant differences in clinicopathologic findings were observed between the two groups, except for the rate of minimal invasive surgery (P=0.004) and cancer stage (P=0.002). No differences in the rate of morbidity (P=0.353) and admission duration (P=0.391) were observed between the two groups. Gastrofiberscopic findings showed a significant reduction of bile reflux in the remnant stomach in the Roux en Y group (P=0.019). Conclusions: When compared with Billroth-I reconstruction, Roux en Y reconstruction using the double stapler technique was found to reduce bile reflux in the remnant stomach without increasing postoperative morbidity. Based on these results, we planned to begin a randomized controlled clinical trial for comparison of Roux en Y reconstruction using this method with Billroth-I anastomosis.

A titanium based screw shaped dental implant was first introduced by Branemark and a treatment protocol where the restoration of edentulous area by connecting abutment after the osseointegration of the titanium surface of the implant and surrounding bone structure has been proposed. Although this protocol is widely accepted as a standard up to date, the healing duration of 3-6 months as well as the need for provisional prostheses during this period present as a major drawback. Immediate loading has been accomplished through the advent of various implant designs, enforced surface treatments, diverse forms of abutment, and delicate surgical techniques together with the increase in demand from the patients. The success rate of the immediate loading technique has been first reported as 85.7% by Dr. Schnitman in 1990 which recently has been reported up to 100% in the case of immediate loading in single tooth by Dr. Kan. To ameliorate the success rate of immediate loading technique, selection of patients presenting a sound bone quality and quantity, acquiring primary stability through delicate surgical techniques and fabrication of prostheses which accounts for biological stabilities should all be taken into consideration. This presentation introduces the understanding of biological stability of immediate loading, various methods for measurement of stability and clinical cases regarding immediate loading technique.

Purpose: Verrucous carcinoma is a rare, low-grade and well-differentiated squamous cell carcinoma, representing as a warty tumor. Estimation of the incidence for cutaneous lesions is not available because they are rare. We describe a case of verrucous carcinoma, a rare type, complication of a chronic pressure ulcer of duration more than 15 years. Methods: A 17-year-old boy presented with a large lesion involving the sacral area, which had been neglected for about 15 years. He had a history of surgical extirpation 2 years ago, but not cured. Examination revealed a cauliflower-like mass arising from an irregularly oval-shaped tumor which was $6.0{\times}4.5cm$ in size with signs of infection and ulcer. The lesion involved the sacrococcygeal area, spreading to both medial gluteal regions. The perianal skin did not appear to be directly affected. Results: A preoperative punch biopsy revealed a extremely well differentiated verrucous carcinoma. There were positive results in immunohistochemistry in the items of p53, p63, Ki-67. An 'en-bloc' excision of the tumor with the clinically normal surrounding tissue was carried out. Reconstruction was achieved by local regional flap. Histopathological findings of the excised area fully confirmed the preoperative biopsy report. It remained free of recurrence for a period of about 8 months. Conclusion: We believe that in patients with buttock involvement, regardless of the extent of such tumors, surgical therapy should be considered as the first-choice of treatment as reconstruction can be performed without excessive impairment for the patient.

Objective: Posterior lumbar interbody fusion(PLIF), the current leading method of pedicle screw fixation combined with interbody fusion via posterior route, sometimes requires too much destruction of the facet joint than expected especially for the patient with a narrow spine. On the other hand, tranforaminal lumbar interbody fusion(TLIF) technique provides potential advantages over PLIF and can be chosen as a better surgical alternative to more traditional fusion methods in certain surgical conditions. Methods: From October 1999, 99 PLIF and 29 TLIF procedures were done for the patients with spinal stenosis and instability. Radiological data including the interpedicular distance and the size of the pedicles as well as the clinical parameters were collected retrospectively. The degree of resection of the inferior articular process was compared with the interpedicular distance in each patient who received PLIF. Results: No significant differences were found between PLIF and TLIF regarding the operation time, blood loss, duration of hospital stay, or short term postoperative clinical result. There were no complication with TLIF, but PLIF resulted in 9(9.1%) complications. During PLIF procedure, all patients(n=24) except one with the interpedicular distance shorter than 27mm required near complete or complete resection of the inferior articular processes, whereas only 6(31.5%) of 19 patients with the interpedicular distances longer than 30mm required the similar extent of resection. Conclusion: TLIF is better than PLIF in terms of the complication rate. The patient who had narrow interpedicular distance(<27mm) might be better candidate for TLIF.

This study was performed to describe the longitudinal management of recurrent temporomandibular joint (TMJ) ankylosis from infancy to adulthood in perspective of surgical and orthodontic treatment. A 2-year-old girl was referred with chief complaints of restricted mouth opening and micrognathia due to bilateral TMJ ankylosis. For stage I treatment during early childhood (6 years old), high condylectomy and interpositional arthroplasty were performed. However, TMJ ankylosis recurred and symptoms of obstructive sleep apnea (OSA) developed. For stage II treatment during early adolescence (12 years old), gap arthroplasty, coronoidectomy, bilateral mandibular distraction osteogenesis, and orthodontic treatment with extraction of the four first premolars were performed. However, TMJ ankylosis recurred. Because the OSA symptoms reappeared, she began to use a continuous positive airway pressure device. For stage III treatment after completion of growth (20 years old), low condylectomy, coronoidectomy, reconstruction of the bilateral TMJs with artificial prostheses along with counterclockwise rotational advancement of the mandible, genioglossus advancement, and orthodontic treatment were performed. After stage III treatment, the amount of mouth opening exhibited a significant increase. Mandibular advancement and ramus lengthening resulted in significant improvement in the facial profile, Class I relationships, and normal overbite/overjet. The OSA symptoms were also relieved. These outcomes were stable at the one-year follow-up visit. Since the treatment modalities for TMJ ankylosis differ according to the duration of ankylosis, patient age, and degree of deformity, the treatment flowchart suggested in this report could be used as an effective guideline for determining the appropriate timing and methods for the treatment of TMJ ankylosis.

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: We present our experience involving the management of this disease, identifying prognostic factors affecting treatment outcomes. Methods: The patients treated for Fournier gangrene at our institution were retrospectively reviewed. Data collected included demographics, extent of soft tissue necrosis, predisposing factors, etiological factors, laboratory values, and treatment outcomes. The severity index and score were calculated. Multivariate regression analysis was used to determine the association between potential predictors and clinical outcomes. Results: A total of 41 patients (male:female = 33:8) were studied. The mean age was 54.4 years (range, 24-79 years). The most common predisposing factor was diabetes mellitus (n = 19, 46.3%). Sixteen patients (39.0%) were current smokers. Seven patients had chronic kidney disease. The most frequent etiology was urogenital lesion (41.5%). The mortality rate was 22.0% (n = 9). Multivariate regression analyses showed that extension of necrosis beyond perineal/inguinal area and pre-existing chronic kidney disease were significant and independent predictors of mortality. Extension of necrosis beyond perineal/inguinal area was a significant predictor of increased duration in the intensive care unit and hospital stay. In addition, pre-existing chronic kidney disease was a significant predictor of flap reconstruction in the wound. Conclusion: Fournier gangrene with extensive soft tissue necrosis and pre-existing chronic kidney disease was associated with poor prognosis and complexity of patient management. Early recognition of dissemination and premorbid renal function is essential to reduce mortality and establish a management plan for this disease.
