  • Purpose: Laparoscopic wedge resection of gastric submucosal tumor may be difficult in case of the endophytic mass or the mass located unreachable area such as cardia, and intragastric approach can be useful. We would present the experiences of the intragastric wedge resection. Materials and Methods: There were 7 patients diagnosed as gastric submucosal tumor and underwent the intragastric wedge resection at Surgery, Chungnam National University Hospital. We reviewed medical record. Results: There were 3 male and 4 female. Mean age was 65 years-old (57~73). Mean body mass index was 26.28 kg/$m^2$ (21.28~35.30). Location of lesions was 4 cardia, 2 fundus and 1 midbody, respectively. Mean operation time was 83.6 minutes (70~105). All patients were healed without any complication. Mean postoperative hospital stay was 5.4 days (4~6). Mean size was 2.7 cm (2.3~3.8). Pathologic finding was 5 gastrointestinal stromal tumor and 2 leiomyoma. Conclusions: The single incision intragastric wedge resection of gastric submucosal tumor is feasible and acceptable, especially in mass of gastric upper part.

  • Background Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are still controversial. In this article, we suggest a simple reduction method using a subbrow incision as a treatment for isolated anterior sinus fractures. Methods Between March 2011 and March 2014, 13 patients with isolated frontal sinus fractures were treated by open reduction and internal fixation through a subbrow incision. The subbrow incision line was designed to be precisely at the lower margin of the brow in order to obtain an inconspicuous scar. A periosteal incision was made at 3 mm above the superior orbital rim. The fracture site of the frontal bone was reduced, and bone fixation was performed using an absorbable plate and screws. Results Contour deformities were completely restored in all patients, and all patients were satisfied with the results. Scars were barely visible in the long-term follow-up. No complications related to the procedure, such as infection, uncontrolled sinus bleeding, hematoma, paresthesia, mucocele, or posterior wall and brain injury were observed. Conclusions The subbrow approach allowed for an accurate reduction and internal fixation of the fractures in the anterior table of the frontal sinus by providing a direct visualization of the fracture. Considering the surgical success of the reduction and the rigid fixation, patient satisfaction, and aesthetic problems, this transcutaneous approach through a subbrow incision is concluded to be superior to the other reduction techniques used in the case of an anterior table frontal sinus fracture.

  • Objectives : Essential hyperhidrosis is a common condition characterized by excessive body sweating. Excessive sweating beyond what is necessary to maintain normal body temperature need not be considered pathological unless it interferes with one's occupation and/or life-style. The existing non-operative therapeutic options seldom give sufficient relief or show a transient effect. In this regard, the thoracic sympathectomy may provide a definitive cure. In the past, surgical procedures were highly invasive and caused significant morbidity, but the minimally invasive thoracoscopic procedure provided detailed visualization of sympathetic ganglia and is associated with minimally postoperative morbidity. Nowadays, thoracoscopic transthoracic sympathectomy is accepted as the treatment of choice for essential hyperhidrosis. In palmar hyperhidrosis, however, the level of sympathetic chain to be blocked has been somewhat obscure. It is assumed that the incidence of compensatory hyperhidrosis may closely related to the extent of thoracic sympathectomy. Material & Methods : To compare the results of posterior midline approach with endoscopic sympathectomy, and the results of T2 with T2, 3 sympathectomy or sympathicotomy, we retrospectively studied 62 patients treated for palmar hyperhidrosis between September 1993 and May 2000. We reviewed medical records and recently interviewed the patients by telephone calls. Results : The treatment effect of T2 sympathectomy is no different from T2, 3 sympathectomy. But, the incidence of compensatory hyperhidrosis is less in the T2 sympathectomy group than the T2, 3 sympathectomy group. Conclusion : Thoracoscopic sympathectomy is considered a simple, safe, and effective method for treating palmar hyperhidrosis, with a shorter operation time, fewer hospital days, and a better cosmetic result, as compared with the open approaches. However, sympathicotomy seems to provide the advantages of a limited extent of denervation and the resultant decrease of compensatory hyperhidrosis compared to sympathectomy.

  • Background Facial rejuvenation can be achieved using a variety of techniques. Since minimally invasive procedures for face lifting have become popular because of their convenience and short operating time, numerous minimally invasive surgical procedures have been developed. In this study, a nonabsorbable polypropylene mesh is introduced as a new face lifting instrument, with the nasolabial fold as the main target area. In this paper, we report the efficacy and safety of a polypropylene mesh in midface rejuvenation. Methods Thirty-three subjects with moderate-to-severe nasolabial folds were enrolled from two medical institutions for a noncomparative single-sample study. A mesh was inserted above the superficial muscular aponeurotic system layer, reaching the nasolabial folds through a temporal scalp incision. After 3 weeks, the temporal end of the mesh was pulled to provide a lifting effect. Then, the mesh was fixed to the deep temporal fascia using nonabsorbable sutures. To evaluate efficacy, we compared the scores on the Wrinkle Severity Rating Scale and a visual analog scale for patient satisfaction between the baseline and 7 weeks postoperatively. In addition, we evaluated safety based on the incidence of adverse events. Results The treatment was deemed effective at improving wrinkles in 23 of 28 cases, and patient satisfaction improved significantly during the study period. There were seven cases of skin or subcutaneous tissue complications, including edema and erythema, but there were no suspected serious adverse events. Conclusions Face lifting using a nonabsorbable mesh can improve nasolabial folds without serious adverse effects. Thus, this technique is safe and effective for midface rejuvenation.

  • Background: Stenting is an effective treatment option for tracheal collapse in dogs. Cross-braided tracheal stents are currently the norm in veterinary medicine, but cross-and-hook braided stents have recently been adopted in human medicine. We examined whether stents manufactured using this novel braiding technique provided additional advantages for the treatment of tracheal collapse in dogs. Objectives: To evaluate the outcomes of cross-and-hook braided stent implantation in the treatment of tracheal collapse in dogs. Methods: The medical records of 22 client-owned dogs that underwent luminal placement of cross-and-hook braided Fauna Stents for the treatment of tracheal collapse between January 2018 and July 2021 were examined and data on canine signalment, clinical signs, diagnostic test results, surgical outcomes, and postoperative complications were retrieved and analyzed statistically. Results: Twenty-six stents were surgically implanted, with 20 dogs (90.9%) receiving one stent and the remaining two (9.1%) receiving two or more stents. All dogs survived the procedure. The median survival time at a median follow-up of 990 days was 879 days. At the final follow-up examination, loss or mild improvement of cough was observed in all dogs. Conclusions: Compared with conventional lumen stents, the cross-and-hook braided Fauna Stent offered a higher survival rate and improved clinical symptoms in all patients. The results of this study suggest that the Fauna Stent may be a promising treatment option for dogs with tracheal collapse.

  • Background: With recent advances in cardiac surgery through minimal access, mini-thoracotomy has emerged as an excellent alternative for cardiac myxoma resection. This study analyzed the surgical results of this approach, focusing on postoperative cerebral embolism and tumor recurrence. Methods: We retrospectively reviewed 64 patients (mean age, 56.0±12.1 years; 40 women) who underwent myxoma resection through mini-thoracotomy from October 2008 to July 2020. We conducted femoral cannulation and antegrade cardioplegic arrest in all patients. Patient characteristics and perioperative data, including brain diffusion-weighted magnetic resonance imaging (DWI) findings, were collected. Medium-term echocardiographic follow-up was performed. Results: Thirteen patients (20.3%) had a history of preoperative stroke, and 7 (11.7%) had dyspnea with New York Heart Association functional class III or IV. Sixty-one cases (95.3%) had myxomas in the left atrium. The mean cardiopulmonary bypass and cardiac ischemic times were 69.0±28.6 and 34.1±15.0 minutes, respectively. Sternotomy conversion was not performed in any case, and 50 patients (78.1%) were extubated in the operating room. No early mortality or postoperative clinical stroke occurred. Postoperative DWI was performed in 32 (53%) patients, and 7 (22%) showed silent cerebral embolisms. One patient underwent reoperation for tumor recurrence during the study period; in that patient, a genetic study confirmed the Carney complex. Conclusion: Mini-thoracotomy for cardiac myxoma resection showed acceptable clinical and neurological outcomes. In the medium-term echocardiographic follow-up, reliable resection was proven, with few recurrences. This approach is a promising alternative for cardiac myxoma resection.

  • Bone cement augmentation procedures have been getting more position as a minimally invasive surgical option for osteoporotic spinal fractures. However, complications related to these procedures have been increasingly reported. We describe a case of bone cement dislodgement following cement augmentation procedure for osteoporotic spinal fracture by reviewing the patient's medical records, imaging results and related literatures. A 73-year-old woman suffering back and buttock pain following a fall from level ground was diagnosed as an osteoporotic fracture of the 11th thoracic spine. Percutaneous kyphoplasty was performed for this lesion. Six weeks later, the patient complained of a recurrence of back and buttock pain. Radiologic images revealed superior dislodgement of bone cement through the 11th thoracic superior endplate with destruction of the lower part of the 10th thoracic spine. Staged anterior and posterior fusion was performed. Two years postoperatively, the patient carries on with her daily living without any significant disability. Delayed bone cement dislodgement can occur as one of complications following bone cement augmentation procedure for osteoporotic spinal fracture. It might be related to the presence of intravertebral cleft, lack of interdigitation of bone cement with the surrounding trabeculae, and possible damage of endplate during ballooning procedure.

  • 관절강세정술은 통상의 보존적 치료법에 실패한 측두하악관절장애 환자에서 합병증의 위험성이 높은 침습적인 외과적 수술법에 대신하여 첫 번째로 고려될 수 있는 치료법이다. 본 증례의 환자들은 측두하악관절의 비정복성 관절원판변위로 진단되어 지속적인 교합안정장치치료, 행동요법치료, 물리치료, 약물치료 등의 보존적 치료에도 불구하고 심한 관절동통과 하악운동범위의 제한을 호소하였다. 따라서 보존적 치료법에 잘 반응하지 않는다고 판단하여 반복적인 관절강세정술을 시행하였고, 시술직후 유의한 동통감소, 하악운동범위의 개선과 함께 양호한 치료경과를 나타냈다. 관절강세정술은 최소의 침습성을 지니는 가장 보존적인 외과적 술식으로서 통법의 보존적 치료에 반응하지 않는 비정복성 관절원판변위 환자를 상기 증례와 같이 적절히 선택한다면 측두하악관절장애의 동통과 기능제한에 효과적인 보조적 치료법이라고 생각된다.

  • Background: Radicular pain, associated with herniated intervertebral disc, has been treated with either conservative treatments or a traditional surgical discectomy. Several modalities for minimally invasive percutaneous procedures have been developed as alternatives to a surgical discectomy. Percutaneous decompression using a $Dekompressor^{(R)}$ probe has been recently introduced. Herein, we report the outcome of percutaneous decompression with a $Dekompressor^{(R)}$ for the treatment of a herniated intervertebral disc. Methods: Between August 2004 and April 2005, percutaneous decompression was performed using a $Dekompressor^{(R)}$, 1.5-mm percutaneous lumbar discectomy probe in 17 patients with a herniated lumbar intervertebral disc resistant to conservative treatments, with the results reviewed retrospectively. The procedure was performed under fluoroscopic guidance after local anesthesia. Disc access was gained with a posterolateral approach on the symptomatic side and intradiscal placement of the discectomy probe in the herniated disc confirmed from the anteroposterior and lateral views on the fluoroscopy. Results: We obtained satisfactory clinical results in 14 patients with a decrease in the initial Visual analogue scale (VAS) of more than 55% and the elimination or reduction of analgesic medication, with a follow-up of 3 to 11 months. Conclusion: We concluded that a percutaneous discectomy with a $Dekompressor^{(R)}$ probe might be an effective alternative for the treatments of painful disc herniations resistant to conservative managements when performed under proper selection criteria.

  • Laparoscopic proximal gastrectomy (LPG) is theoretically a superior choice of minimally-invasive surgery and function-preserving surgery for the treatment of proximal early gastric cancer (EGC) over procedures such as laparoscopic total gastrectomy (LTG), open total gastrectomy (OTG) and open proximal gastrectomy (OPG). However, LPG and OPG are not popular surgical options due to three main concerns: the first, oncological safety; the second, functional benefits; and the third, anastomosis-related late complications (reflux symptoms and anastomotic stricture). Numerous recent studies have concluded that OPG and LPG present similar oncological safety profiles and improved functional benefits when compared with OTG and LTG. While OPG with modified esophagogastrostomy does not provide satisfactory results, OPG with modified esophagojejunostomy showed similar rates of anastomosis-related late complications when compared to OTG. At this stage, no standard reconstruction method post-LPG exists in the clinical setting. We recently showed that LPG with double tract reconstruction (DTR) is a superior choice over LTG for proximal EGC in terms of maintaining body weight and preventing anemia. However, as there is no definitive evidence in favor of LPG with DTR, a randomized clinical trial comparing LPG with DTR to LTG was recommended. This trial, the Korean Laparoscopic Gastrointestinal Surgery Study-05 (NCT01433861), is expected to assist surgeons in choice of surgical approach and strategy for patients with proximal EGC.
