In neurogenic equinovarus deformity, surgical intervention such as tendon transfer or osteotomy can be expected to improve symptoms. However, in rare cases of hereditary spastic paraplegia, the deformity and paralysis gradually progress. So limited operation and early post-operative rehabilitation are preferred to aggressive operation. We would like to report our clinical experience with one case of hereditary spastic paraplegia patient with reference review. A 40 year-old male, given tendon transfer of ankle and foot and tendo achilles lengthening 10 years ago, complained about aggravated spastic paraplegia which resulted in dynamic equinovarus and limited walking ability since his operation. Family history showed limited walking ability of his father with gradually progressing spastic paralysis and he was diagnosed as hereditary spastic paraplegia type I. We had performed a limited operation such as tendo achilles and tibialis posterior lengthening to induce plantigrade standing and walking with crutch. As a result, the patient was able to maintain a stabilized standing posture and walk after the operation. Hereditary spastic paraplegia presents with a progressive paralysis which limits rehabilitation after tendon transfer, and the symptoms can be aggravated. Therefore, considering potential hereditary neurogenic disorders in paients with equinovarus deformity and performing limited operative procedures seem to be important.
Recently the thoracic injuries have been markedly increasing due to the vast increase of traffic accident, industrial disaster, and incidental accident as well as the frequent use of the murderous weapons including gun or rifle. Because the thoracic injuries could involve the heart, lung, and great vessels, and would influence the lives, prompt diagnosis and adequate treatment are essential. Most of thoracic injuries can be managed with the conservative treatment and simple surgical procedure such as closed thoracostomy, but certain cases require open thoracotomy to preserve lives and to return to their normal environment. The authors have analysed the result of 53 cases of open thoracotomy after thoracic injuries mainly according to the patient`s chart review. The mean age was 33.4 years old and male to female ratio was about 5: l. Injury mechanisms that elicited thoracic trauma indicated for open thoracotomy were penetrating[47%] and non-penetrating[53%] injuries. The Most common type of the thoracic lesion was hemothorax with or without pneumothorax and diaphragm rupture was the second. 58\ulcornero of thoracic injuries were accompanied by abdominal injuries and 47% by bone fractures. 34 patients were operated within 24 hours after injury and their average elapsed time was 13.6 hour. The remained patients were operated after 24 hours and their average elapsed time was 7.8 days. 71 cases of operative procedures containing some overlappings were performed: diaphragm repair[28], bleeding control[12], pulmonary and cardiac repair[4 cases] Postoperative complication rate was 32.1% and operative mortality rate was 9.4%[5/53].
Coarctation of aorta is rather common congenital cardiovascular disease in the western contries, but it is known to be less than 2 % in Korea. From June 1986 to December 1992, seven patients of surgically treated coarctation of aorta who were less than 2 years old, were experienced at Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The patients included six male and one female, with ages in the range of one month and 24 months. Four patients were preductal type and three juxtaductal. Associated cardiac anomalies were present in all patients and they were PDA[6 cases], ASD[3], VSD[2], bicuspid aortic valve[2], aortic stenosis[1], mitral regurgitation[1], and tricuspid regurgitation[1]. The operative procedures were four end to end anastomosis and three subclavian flap aortoplasty. Mean aortic cross clamping times were 37.3 minutes in patients with end to end anastomosis and 30.3 minutes in patients with subclavian flap aortoplasty. There were two operative deaths in patients who were treated with subclavian flap aortoplasty and pulmonary artery banding. One patient who had been treated with subclavian flap aortoplasty was complicated with postoperative mild paraplegia in lower limb. Pulmonary artery banding has been disappointing in our patients, and the data was suggestive that earlier total repair of complicated coarctation might improve survival.
Between February and July 1992, videothoracoscopic bullectomy was performed in nineteen patients with primary spontaneous pneumothorax. The indications of this surgery are recurrent in 12, persistent airleakage in 4 and previous contralateral pneumothorax in 3 patients. For the good operative field, we used double lumen endotracheal tube and put the CO2 gas into the thoracic cavity to make the lung collapse. We usually apply the endoGIA or electric cauterization for handling the bleb or bullae and there were 9 cases with of endoGIA only, 4 electric cauterization only and 6 both procedures. To evaluate the advantage of the Videothoracoscopic surgery, we compared surgical results with that of the tho-racotomy group[19 patients]. There were significant differences in operative time[93.8$\pm$41.9 min and 17.1$\pm$53.9 min, p< 0.01] and postoperative airleakage duration[35.6$\pm$113.3 hours and 117.9$\pm$214.4 hours, p<0.05] between the Videothoracoscopy and thoracotomy group. Tube indwelling time was shortened in Videothoracoscopy group[p<0.05]. The hospital stay was very short[p<0.01] and the patients needed analgesic injection less frequentley in videthoracoscopic group[p<0.05] In conclusion, we prefer the Videothoracoscopic procedure to the thoracotomy in uncomplicateed patients with pneumothorax because of simple procedure and good results.
Since the first laparoscopic gastrectomy for cancer was reported in 1994, minimally invasive surgery is enjoying its wide acceptance. Numerous procedures of this approach have developed, and many patients have benefited from its effectiveness, which has been recently demonstrated for early gastric cancer. However, since laparoscopic surgery is not exempt from some limitations, the robotic surgery system was introduced as a solution by the late 1990's. Many experienced surgeons have embraced this new emerging method that provides undoubted technical and minimally invasive advantages. To date, several studies have concentrated to this new system, and have compared it with open and laparoscopic approach. Most of them have reported satisfactory results concerning the post-operative short-term outcomes, but almost all believe that the role of robotic gastrectomy is still out of focus, especially because long-term outcomes that can prove robotic oncologic equivalency are lacking, and operative costs and time are higher in comparison to the open and laparoscopic ones. This article is a review about the current status of robotic surgery for the treatment of gastric cancer, especially, focusing on the technical aspects, comparisons to other approaches and future prospects.
Background: In this study, we present recent trends in heart valve surgery in Korea through analyses of data from the Korea Heart Valve Surgery Registry (KHVSR). Methods: We enrolled 8,981 patients who were registered in the KHVSR from 2017 to 2020. Yearly trends in patients' baseline characteristics, surgical profiles, and early mortality rates were explored. The observed/expected mortality ratio (O/E ratio), calculated from the actual mortality in the KHVSR and the predicted mortality estimated using the EuroSCORE II, was also analyzed. Results: The proportion of aortic valve surgery significantly increased from 56.8% in 2017 to 60.3% in 2020. The proportion of all combined procedures and minimally invasive surgery significantly increased over the 4-year study period. The operative mortality rate was 2.9% in the entire cohort, while mitral valve repair showed the lowest mortality risk (0.9%). The mortality rates of isolated aortic valve replacement (AVR) significantly decreased from 2.1% in 2017 to 0.8% in 2020 (p=0.016). Overall, the O/E ratio was 0.784 (95% confidence interval [CI], 0.677-0.902) demonstrating significantly lower actual mortality risks than expected based on the EuroSCORE II. In particular, the O/E ratios were as low as 0.364 (95% CI, 0.208-0.591) for isolated AVR. Conclusion: The recent data from the KHVSR showed increasing trends for complex procedures and minimally invasive surgery in heart valve surgery in Korea, and demonstrated remarkably low risks of operative mortality.
Objective : The focus of aneurysm surgery is eliminating unnecessary operative manipulations and preparing the surgeon for any crises that might arise. With this concept in mind, we have tried resection of the gyrus rectus without routine sylvian fissure dissection in selected patients with anterior communicating artery (ACom) aneurysms, and compared these results with those from the conventional transsylvian approach. Methods : This retrospective study included 231 surgically treated patients with ACom aneurysms from March, 1997 to May, 2005. The patients were divided into two groups : Group A (96 with sylvian fissure dissection, March, 1997-December, 2000) and Group B (135 without sylvian fissure dissection, January, 2001-May, 2005). Overall surgical outcomes were compared, and operative times have been prospectively recorded since January, 04 to evaluate how this maneuver affected the length of surgical procedures. Results : All aneurysms were satisfactorily clipped, and there was no evidence of increased number of procedure-related retraction injuries in group B. Overall outcome was good in 186 (80.5%); 76 (79.2%) in group A, and 110 (815%) in group B ($x^2$ test, p=0.79). In good clinical grade of group A, good outcome was observed in 60 patients (89.6%) and in group B, 97 patients (94.2%) (Fisher's exact test, p=0.38) (Fig. 2). Conclusion : In this study, eliminating the step of sylvian fissure dissection by gentle lateral basal-frontal retraction to the side of the sylvian fissure did not increase morbidity and mortality. However, we do not intend to modify the standard approach to the ACom aneurysm that is familiar to and has been mastered by many others. Rather, we report our experience on the basis of our anatomic understanding of the technique and its results.

Background: The purpose of this report is to describe the perioperative outcomes of standard carotid endarterectomy (CEA) with general anesthesia, routine shunting, and tissue patching in symptomatic carotid stenoses. Materials and Methods: Between October 2007 and July 2011, 22 patients with symptomatic carotid stenosis (male/female, 19/3; mean age, $67.2{\pm}9.4$ years) underwent a combined total of 23 CEAs using a standardized technique. The strict surgical protocol included general anesthesia and standard carotid bifurcation endarterectomy with routine shunting. The 8-French Pruitt-Inahara shunt was used in all the patients. Results: During the ischemic time, the shunts were inserted within 2.5 minutes, and 5 patients (22.7%) revealed ischemic cerebral signals (flat wave) in electroencephalographic monitoring but recovered soon after insertion of the shunt. The mean shunting time for CEA was $59.1{\pm}10.3$ minutes. There was no perioperative mortality or even minor stroke. All patients woke up in the operating room or the operative care room before being moved to the ward. One patient had difficulty swallowing due to hypoglossal nerve palsy, but had completely recovered by 1 month postsurgery. Conclusion: Routine shunting is suggested to be a safe and reliable method of brain perfusion and protection during CEA in symptomatic carotid stenoses.
Ten cases with esophageal foreign body were treated surgically from July 1980 to October 1995 at the Departme t of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The mean age was 45.3 years, with a range from 25 to 71. Out of ten cases, 6 were female and four were male. Common symptoms were dysphagia, fever, foreign body sensation and neck pain. Three cases of foreign bodies were of fish bones, two of bubble paclcage of drugs, one case of a Eeer bottle cap, one of a piece glass, one of a bathtub plug, one of chicken and one of a bean. The diagnosis was established by esophagography using a water soluble contrast material and esophagoscopy. Among of ten cases, two had esophageal stricture due to the ingestion of Aye at a young age. One case had experienced psychological problems. All foreign bodies were removed by surgical procedures. Five cases were treated by cervical esophagostomy, one case by right thoracotomy, one case by retrograde bougienation through gastrostomy and two cases by cervical incision and drainage for cervical abscess. Three cases developed pos operative esophageal leaks which healed spontaneously and transient hoarseness developed in one case. One case developed traumatic pneumothorax and subcutaneous emphysema which was treated by closed thoracostomy. There were no operative deaths. C(ocean J Thorac Cardiovasc Surg 1997;30:1117-20)
Background Surgical site infections (SSIs) result in significant patient morbidity following immediate tissue expander breast reconstruction (ITEBR). This study determined a single institution's 30-day SSI rate and benchmarked it against that among national institutions participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Methods Women who underwent ITEBR with/without acellular dermal matrix (ADM) were identified using the ACS-NSQIP database between 2005 and 2011. Patient characteristics associated with the 30-day SSI rate were determined, and differences in rates between our institution and the national database were assessed. Results 12,163 patients underwent ITEBR, including 263 at our institution. SSIs occurred in 416 (3.4%) patients nationwide excluding our institution, with lower rates observed at our institution (1.9%). Nationwide, SSIs were significantly more common in ITEBR patients with ADM (4.5%) compared to non-ADM patients (3.2%, P=0.005), and this trend was observed at our institution (2.1% vs. 1.6%, P=1.00). A multivariable analysis of all institutions identified age ${\geq}50$ years (odds ratio [OR], 1.4; confidence interval [CI], 1.1-1.7), body mass index ${\geq}30kg/m^2$ vs. < $25kg/m^2$ (OR, 3.4; CI, 2.6-4.5), and operative time >4.25 hours (OR, 1.9; CI, 1.5-2.4) as risk factors for SSIs. Our institutional SSI rate was lower than the nationwide rate (OR, 0.4; CI, 0.2-1.1), although this difference was not statistically significant (P=0.07). Conclusions The 30-day SSI rate at our institution in patients who underwent ITEBR was lower than the nation. SSIs occurred more frequently in procedures involving ADM both nationally and at our institution.
