From March 1989 to June 1994, 24 casesof esophageal cancer were treated surgically. Among 24, male was 22 cases, female was 2 cases, and the age ranged from 46 to 75, the mean was 59.8. Symptoms were dysphagia[86.9% , weight loss[65.2% and retrosternal pain or discomfort[47.8% . The tumor was located cervical esophagus in two, upper esophagus in three, middle esophagus in 12 and lower esophagus in 7. Among 24 patients, 22 were curative resection, partial esophagectomy with esophagogastrostomy[18 cases or colon interposition [3 cases , with total esophagectomy with musculocutaneous flap[1 case , with feeding jejunostomy or gastrostomy in two cases.Postoperative complications revealed 10 patients[45.4% , as followed ; pleural effusion and pneumonia in 5, passage disturbance in 4, empyema and wound infection in 3, esophagopleural fistula and sepsis in 2, anastomotic site leakage and respiratory failure in each 1. The operative mortality was 13.6 % [3/22 and causes of death were respiratory failure in 1 case and sepsis in 2 cases.During follow-up work, 8 cases died during follow-up period, mean survival time was 15.2 months in curative resection group. One year survival rate was 55.3% in resected group. Also, cancer recurrence revealed in 1 cases.

We experienced a case of interrupted aortic arch[Type A] associated with PDA, VSD, mitral regurgitation and single coronary artery. The patient was 7 years old boy, who showed congestive heart failure[NYHA functional class III]. One stage total correction was performed under profound hypothermia with total circulatory arrest. Aortic continuity was established using PDA with anterior wall of main pulmonary artery flap. VSD was closed with Dacron patch and mitral regurgitation repaired by Reed`s annuloplasty method. The postoperative cardiac catheterization revealed no pressure gradient between ascending aorta and descending aorta, decreased pulmonary artery pressure and trivial residual shunt[Qp/Qs: 1.28]. The aortogram showed good continuity of the aorta without narrowing of the anastomotic site. During the period of 1 year follow up, heart failure symptoms were nearly subsided.

Colon interposition is commonly used for esophageal reconstruction in patients with a previous gastrectomy. However, when colon interposition fails and alternative reconstruction is required, there are few options for reconstructing the long segment from the esophagus to the stomach. Here, we report on cases of esophagogastric reconstruction with limited alternative options after the failure of transverse and left colon interposition. In these cases, reconstruction was performed using two different microvascular methods: double-pedicle jejunal free flap and supercharged ileocolic interposition graft.

Objectives: The goal of this retrospective study was to determine the significance and impact of several factors on the alveolar cleft bone grafting procedure. Materials and Methods: The medical records were reviewed. In addition, x-rays were checked. The size of every cleft was measured in this retrospective study. The analyzed factors included sex, age, type of cleft, size of the cleft, and the type of flap used in surgery. The patients were characterized into group A (no complications, Bergland scale 1 or 2), group B (complications or Bergland scale 3), or group C (failure cases). Statistical analysis was performed with a P-value set at 0.05. Results: There were 32 cases in group A, 26 in group B, and 9 in group C. Multinomial logistic regression showed an association between the type of the cleft and the size of the cleft, with the presence of complications, or achieving type 3 on the Bergland scale, with odds ratios of 5.118 and 6.000, respectively. The type of cleft was related to failure with an odds ratio of 4.833. Given a small sample, statistical analysis could not be performed to evaluate the relationship between the size of the cleft and group C. Age, sex, and the type of the flap were not significant factors. Conclusion: The cleft size of more than 10 mm and bilateral clefts were listed regarding their effect on the procedure. Clinicians should not overlook these factors. In addition, patients must be informed of any risks that are present.

The most common anatomic variant seen in donor kidneys for renal transplantation is the presence of multiple renal arteries, which can cause an increased risk of complications. Accessory renal arteries should be anastomosed to the proper source arteries to improve renal perfusion via the appropriate vascular reconstruction techniques. In microsurgery, 2 kinds of vascular augmentation methods, known as 'supercharging' and 'turbocharging,' have been introduced to ensure vascular perfusion in the transferred flap. Supercharging uses a distant source of the vessels, while turbocharging uses vascular sources within the same flap territory. These technical concepts can also be applied in renal transplantation, and in this report, we describe 2 patients who underwent procedures using supercharging and turbocharging. In one case, the ipsilateral deep inferior epigastric artery was transposed to the accessory renal artery (supercharging), and in the other case, the accessory renal artery was anastomosed to the corresponding main renal artery with a vascular graft (turbocharging). The transplanted kidneys showed good perfusion and proper function. No cases of renal failure, hypertension, rejection, or urologic complications were observed. These microsurgical techniques can be safely utilized for renal transplantation with donor kidneys that have multiple arteries with a lower complication rate and better outcome.

A 60-year-old woman with a history of diabetes mellitus and chronic renal failure was admitted to the hospital with severe pain in the upper lip, which began 4 days prior to admission, accompanied by a bullous lesion and suspected cellulitis in the upper lip. Immediately after admission, as the patient's general condition worsened, tests revealed a non-ST elevated myocardial infarction, septic embolism of the lung, as well as septic shock. Her upper lip suddenly presented a gangrenous and necrotic change, which the tissue and blood culture confirmed to be a Klebsiella pneumoniae infection. After a quick response, the patient's general condition improved. Subsequently, serial debridement was performed to effectively clear away the purulent discharge. While under general anesthesia, the process confirmed full-layer necrosis of the upper lip including the orbicularis oris muscle. Almost half of the entire upper lip sustained a full-layer skin and soft tissue defect, with scar contracture. Six months later, to correct the drooling and lip sealing following the defects, a scar release and an Abbe flap coverage were performed considering both functional and aesthetic aspects. The follow-up revealed a favorable corrective result of the upper lip drooling, and the patient was satisfied from a functional perspective.

Sternal dehiscence is one of the most troublesome complications following cardiac surgery. Treatment failure and consequent lethal results are very common, even with all the efforts to resolve sternal dehiscence such as removal of infectious tissue, muscle flap interposition, and sternal rewiring. We report on a case of sternal osteomyelitis following coronary artery bypass grafting that was successfully treated with wide sternal resection, titanium plate fixation, and pectoralis muscle flap interposition.

Coarctation of aorta is rather common congenital cardiovascular defect in the western countries, but it is known to be rare in Korea. And no coarctation of Aorta has been reported and operated upon during early infancy in Korea. During 4 months period from May 1984 to September 1984, four small infants of coarctation of aorta were seen and treated surgically by subclavian flap aortoplasty in Guro Hospital, Korea University. All infants were male, ranging from 7 days to 54 days old [mean 29 days], weighing between 3.2 Kg and 5.0 Kg [mean 4.1 Kg], and all were in congestive heart failure. Examination of the femoral artery pulse gave in all cases clues to the diagnosis. By Two dimensional echocardiogram, detail anatomical features as well as the diagnosis were revealed and associated anomalies, for example, ventricular septal defect could be seen. Besides one case of isolated coarctation of aorta, other three infants had associated VSD. The 3 patients with VSD were treated by pulmonary artery banding in addition to aortoplasty. The postoperative course were smooth in all patients. In conclusion, coarctation of aorta may not be so rare in Korea as we thought previously. The importance of femoral pulse examination can not be overemphasized for the diagnosis. As we experienced, two-dimensional echocardiography in most cases can substitute those invasive examinations such as angiography and catheterization which carry difficulty and risk in infants.
