Excision of the metastatic pulmonary sarcoma or carcinoma in the selected cases is now the accepted and the most effective method of treatment. From January 1978 to July 1987, 14 patients with metastatic lung cancer were treated surgically at the Department of Thoracic and Cardiovascular Surgery, Catholic University Medical College. Ages ranged from 26 years to 68 years [mean=38.0 years]. Primary sites were uterus in 6 patients, colorectum in 2, sarcoma of extremities in 2, and 1 case of pancreas, kidney, skin and melanoma of hand. Fourteen posterolateral thoracotomies were done and resected the 36 metastatic masses in 14 patients. Surgical mortality was none. The performed procedures of resection were as follows; lobectomy with wedge resection in 2, lobectomy in 3, segmentectomy in 1 and wedge resection in 8. Eleven patients were received radiotherapy or chemotherapy, or both postoperatively. Among the 14 patients, there were 5 survivors. They are 6, 7, 21, 35, and 63 months postoperatively. Among them, 9 patients were dead. Within one year in 2, two years in 6, and three years in l.

The purpose of this study is to report and demonstrate the effect of Korean medical treatment on a wedge resection of a lung patient with mucinous adenocarcinoma. The patient was an 84-year-old female who was diagnosed with mucinous adenocarcinoma and underwent wedge resection. The patient was treated with acupuncture and herbal medicine (Banhahubak-tang and Gamiondam-tang). The EORTC Quality of Life Questionnaire, Core 30 (EORTC QLQ-C30), EORTC Quality of Life Questionnaire, Lung Cancer 13 (EORTC QLQ-LC13), numeric rating scale (NRS), and the Global Assessment (G/A) were used to assess the changes in symptoms, including operation site pain and dyspnea. After treatment, the patient showed improvement in operation site pain and dyspnea, based on the NRS and G/A. However, dyspnea and pain were aggravated based on the EORTC QLQ-C30 and EORTC QLQ-LC13. Therefore, Korean medicine may have a substantial benefit for patients with mucinous adenocarcinoma after wedge resection of the lung.

Background: Contralateral pulmonary resection after pneumonectomy presents considerable challenges, and few reports in the literature have described this procedure. Methods: We retrospectively reviewed the medical records of all patients who underwent contralateral lung resection following pneumonectomy for any reason at our institution between November 1994 and December 2020. Results: Thirteen patients (9 men and 4 women) were included in this study. The median age was 57 years (range, 35-77 years), and the median preoperative forced expiratory volume in 1 second was 1.64 L (range, 1.17-2.12 L). Contralateral pulmonary resection was performed at a median interval of 44 months after pneumonectomy (range, 6-564 months). Surgical procedures varied among the patients: 10 underwent single wedge resection, 2 were treated with double wedge resection, and 1 underwent lobectomy. Diagnoses at the time of contralateral lung resection included lung cancer in 7 patients, lung metastasis from other cancers in 3 patients, and tuberculosis in 3 patients. Complications were observed in 4 patients (36%), including acute kidney injury, pneumothorax following chest tube removal, pneumonia, and prolonged air leak. No cases of operative mortality were noted. Conclusion: In carefully selected patients, contralateral pulmonary resection after pneumonectomy can be accomplished with acceptable operative morbidity and mortality.

Purpose: We compared the results of three surgical procedures of the old neglected Freiberg's disease that was managed with metatarsal head reshaping, metatarsal head resection, and dorsal closing wedge osteotomy. Materials and Methods: From march 1996 to July 2002, five cases in six patients whose metatarsal head collapse already progressed underwent operative treatment. We compared the operative results in the view point of the radiographic follow-up and lesser toe metatrasophalangeal joint scale of AOFAS. Results: There were no further joint destruction and loose body formation. Also, lesser toe metatrasophalangeal joint scale of AOFAS improved from average score, 38.5 (range $22{\sim}49$) of preoperative one to average score, 86.6 (range, $72{\sim}100$). Especially, the 2 cases that underwent dorsal closing wedge osteotomy showed most favorable result and the 2 cases with metatarsal resection showed next favorable result. The 2 cases with intra-articular loose body removal and metatarsal reshaping showed the least effective result among three operative methods. Conclusion: Our Operative experiences of old neglected Freiberg's disease were all satisfactory irrespective of operative options and dorsal closing wedge osteotomy was thought to be most effective method.

Background: Video-assisted thoracoscopic surgery (VATS) pulmonary wedge resection has emerged as the standard treatment for primary spontaneous pneumothorax. Recently, single-port VATS has been introduced and is now widely performed. This study aimed to evaluate the outcomes of the Tower crane technique as novel technique using a 15-mm trocar and anchoring suture in primary spontaneous pneumothorax. Methods: Patients who underwent single-port VATS wedge resection in Chungnam National University Hospital from April 2012 to March 2014 were enrolled. The medical records of the enrolled patients were reviewed retrospectively. Results: A total of 1,251 patients were diagnosed with pneumothorax during this period, 270 of whom underwent VATS wedge resection. Fifty-two of those operations were single-port VATS wedge resections for primary spontaneous pneumothorax performed by a single surgeon. The median age of the patients was $19.3{\pm}11.5$ years old, and 43 of the patients were male. The median duration of chest tube drainage following the operation was $2.3{\pm}1.3days$, and mean post-operative hospital stay was $3.2{\pm}1.3days$. Prolonged air leakage for more than three days following the operation was observed in one patient. The mean duration of follow-up was $18.7{\pm}6.1months$, with a recurrence rate of 3.8%. Conclusion: The tower crane technique with a 15-mm trocar may be a promising treatment modality for patients presenting with primary spontaneous pneumothorax.

Background Ingrown toenail is a common condition that results in chronic pain, recurrent infections, and difficulty in performing daily activities. Our aim is to compare two surgical methods for the treatment of ingrown toenails: wedge resection with curetting versus wedge resection curetting followed by electrocauterization of the nail bed. Methods A prospective, comparative study that included 130 patients with ingrown toenails. All patients had stage II or III disease. We divided the participants into two groups according to the type of surgery and all patients were followed up for 6 months. The outcomes measured were the incidence of postoperative bleeding and infection, recovery time, patient satisfaction, and recurrence rate 6 months after surgery. Results Of the 130 patients included, 59 (45.4%) underwent excision and curetting of the nail matrix (group 1) and 71 (54.6%) underwent excision, curetting, and electrocauterization of the nail matrix (group 2). The postoperative infection rates were 20.3 and 4.2% in the first and second groups, respectively (p = 0.004). Patient satisfaction was 76.3% among the first group, while 91.5% of patients in the second group were satisfied with the results of surgery. Six months postoperatively, recurrence rates were 25.4 and 4.2% in the first and second groups, respectively (p = 0.001). Conclusion Wedge excision and curettage, followed by electrocauterization of the ingrown toenail is a safe treatment modality with a high success rate, that is evident by a lower recurrence rate, and greater patient satisfaction, with no effect on postoperative pain score or recovery time.

Immature teratoma can be viewed as intermediate between mature teratoma and embryonal carcinoma. Unlike the mature teratoma, elements of the three perm cell layers are incompletely differentiated and not arranged in organoid fashion In some area, more mature forms of these tissues may also be seen, Although this tumor is clearly malignant, they may not display clear-cut cytologic features of malignancy. The clinical prognosis is poor. We have experienced one case of recurrent immature teratoma. In first operation[1987, April], tumor of anterior mediastinum was removed with wedge resection of ant. segment of RUL % med. segment of RML. In 2nd operation[1990, June], recurrent teratoma of right inner thoracic wall was resected with partial 5th rib resection and wedge resection of lat. segment of middle lobe. Two months later, the 3rd operation[1990, September] was done, which was a removal of mass on thoracic wall near sup, segment of RLL and partial rib resection of 3rd, 4th & 5th. In November 1990, last operation[4th operation] was made. It was enucleation of walnut sized tumor located between medial segment of RML, and 4th. intercostal space, well encapsulated with endothoracic fascia and invaded into lung parenchyme, Adjuvant chemotherapy was done after each operation, but radiotherapy[5000 Rad] was done only after 1st operation. There was no evidence of recurrence after last operation. The patient is well-being still now.

Purpose: Various laparoscopic wedge resection (LWR) techniques requiring gastrotomy for gastrointestinal stromal tumors (GISTs) of the stomach have been applied to facilitate tumor resection and preserve the remnant gastric volume. However, there is the possibility of cancer cell dissemination during these procedures. The aim of this study was to assess the oncologic safety of LWR with gastrotomy (LWR-G) compared to LWR without luminal exposure. Materials and Methods: Clinicopathologic and operative results of 193 patients who underwent LWR for gastric GIST were retrospectively analyzed from 2003 to 2013. We stratified the patients into two groups: LWR-G and LWR without gastrotomy (LWR-C). Clinicopathologic features, short-term outcomes, and long-term outcomes were compared. Results: A total of 26 patients underwent LWR-G, and 167 patients underwent LWR-C. The LWR-G group showed significantly more anterior wall-located (n=10, 38.5%), intraluminal (n=20, 76.9%), and ulcerative (n=13, 50.0%) tumors than the LWR-C group (n=33, 19.8%; n=96, 57.5%; n=46, 27.5%, respectively). Postoperative short-term outcomes did not differ between the two groups. When tumor staging was compared, no statistical difference was noted. There was no recurrence in the LWR-G group, while 2 patients in the LWR-C group experienced recurrence. The two recurrences in the LWR-C group were found in the liver and in the remnant stomach at 63 and 12 months after the operation, respectively. No gastric GIST-related death was recorded in any group during the study period. Conclusions: LWR-G for gastric GIST is an oncologically safe procedure even for masses with ulcerations.

Backgrounds/Aims: Pancreaticoduodenectomy is the most common procedure for the management of duodenal pathologies. However, it is associated with substantial morbidity and a low risk of mortality. Pancreas-preserving limited duodenal resection (PPLDR) can be performed under specific scenarios. We share our experience with PPLDR and its outcome. Methods: We retrospectively analyzed a prospectively maintained database of patients undergoing limited duodenal resection in the form of wedge (sleeve) resection or segmental resection of one or more duodenal segments from March 2016 to March 2021 at a tertiary care center in North India. Results: During the study period, 10 patients (including 9 males) underwent PPLDR. Five of these 10 patients showed primary duodenal or proximal jejunal pathology, while the remaining five had duodenal pathology involving an adjacent organ tumor. Four patients underwent wedge (sleeve) resection, while the remaining six underwent segmental duodenal resection of one or more duodenal segments. Mean hospital stay was 6 days (range, 3-11 days) without 30-day mortality. Morbidity occurred in 4 patients (Grade I-II, n = 3; Grade III, n = 1). All patients were alive and disease-free at the time of last follow-up. The mean follow-up duration was 23 months (range, 2-48 months). Conclusions: PPLDR is a safe and effective alternative for pancreaticoduodenectomy when selected carefully for specific tumor types and location.

Purpose: This study was performed to evaluate the usefulness of computed tomography (CT) gastrography in the surgical management of a gastric gastrointestinal stromal tumor (GIST). Materials and Methods: We retrospectively analyzed the clinicopathologic data of 38 patients who had undergone CT gastrography from among patients who had gastric GISTS surgically resected at the Department of Surgery, Seoul National University Hospital, between January 2001 and February 2006. We compared CT gastrography data, including tumor size and location and distance from the gastroesophageal junction or pylorus with endoscopic, surgical and pathologic findings. Results: The longitudinal tumor locations on CT gastrography and endoscopy were identical to the surgical findings. For tumor sizes on CT gastrography of less than 5 cm, we performed 11 (42.3%) laparoscopic wedge resections from among 26 cases. In the 12 cases with tumor sizes of 5 cm or over, only 1 (8.3%) laparoscopic wedge resection was performed. When the tumor was located in the middle third of the stomach, a laparoscopic wedge resection was performed in 88.9% (8/9) of the cases, but when it was located in the upper or lower third, a laparoscopic wedge resection was performed in only 13.8% (4/29) of the cases. Conclusion: Three-dimensional information from CT gastrography allows the surgeon to perform preoperative planning, including accurate localization.
