The liver is the major site of metastasis of primary colorectal cancer. Hepatic resection (HR) is considered the standard treatment for colorectal liver metastasis. In highrisk cases, radiofrequency ablation (RFA) can be attempted as an alternative treatment. This study compared the clinical profiles and overall and disease-free survival rates of patients with colorectal liver metastasis undergoing HR and RFA. From 1995 to 2009, we retrospectively analyzed clinical experiences of 43 and 17 patients who had undergone HR and RFA for primary colorectal cancer, respectively. To compare outcomes, we investigated the 3-year overall and disease-free survival rates. The 3-year overall survival rates of patients treated with HR and RFA were 53.5 and 47.1 %, respectively (p=0.285); the disease-free survival rates were 35.0 and 26.9 %, respectively (p=0.211). In the HR and RFA groups, 30 (60.2 %) and 13 (76.5 %) patients developed recurrence, respectively (p=0.604). In the HR group, 1 patient died from postoperative liver failure, and 9 (20.9 %) developed postoperative complications, including wound infection, biliary leakage, intra-abdominal abscess, and pneumonia. In the RFA group, 1 patient (5.9 %) required prolonged inpatient care because of a procedure-related liver abscess. Although HR should be considered the first option for colorectal liver metastasis, RFA can be regarded as a primary treatment modality depending on the patient's characteristics, especially when a patient refuses surgery or has comorbidities.
Our data demonstrated that 85.7% of patients with spleen injuries and 88.2% of patients with liver injuries were managed nonoperatively. Operative management was chosen more selectively, being applied in patients with high grade organ injury scores or abrupt changes in vital status. Our findings will contribute to the available data concerning children with traumatic injuries in Korea.
Objectives: Acupuncture is increasing in popularity as a complementary and alternative medicine. Pneumothorax is the most common and potentially serious adverse effect after acupuncture. This complication can cause fatality in the absence of rapid treatment. Here, we analyze the clinical presentation and discuss prevention of post-acupuncture pneumothorax and an approach to reducing this complication. Methods: Patients presenting with post-acupuncture pneumothorax in our hospital center during 2011-2015 were retrospectively analyzed. Body mass index (BMI), patient's pre-acupuncture chief complaint and disease, and the characteristics associated with pneumothorax were assessed. The diagnosis of pneumothorax was based on clinical presentation and chest radiography. Conservative treatment or thoracostomy was performed. Results: Seventeen patients (15 women and 2 men) with a mean age of 42 years (range: 18–73 years) were included; three were underweight (BMI < 18.5kg/m2), 11 patients had a healthy weight (BMI = 18.5–22.95kg/m2), one was overweight (BMI = 23–24.95kg/m2), and two were obese (BMI ≥ 25 kg/m2). All but one case of bilateral pneumothorax had unilateral pneumothorax (right side: 6; left side: 10). Chest pain or dyspnea, or both were the initial symptoms in all patients. Twelve patients underwent immediate thoracostomy. The patient with bilateral pneumothorax underwent right-side thoracostomy, and subsequently left-side thoracostomy, due to progression of the left-side pneumothorax. Five patients were successfully managed conservatively. All patients had an excellent outcome; all were asymptomatic and exhibited a normal chest X-ray at follow-up. Conclusion: Acupuncturists must be aware that delayed diagnosis and management of pneumothorax are life-threatening, and when symptoms of possible pneumothorax arise, patients should be advised to undergo an appropriate evaluation and intervention, particularly so in those with abnormal BMI.
Acute acalculous cholecystitis (AAC) is defined as acute inflammation of the gallbladder in the absence of gallstones. AAC occurs in patients after major surgery and in the presence of serious co-morbidities such as severe trauma, burns, sepsis, prolonged intravenous hyperalimentation and hemodynamic instability. AAC is rare in patients with none of the established risk factors. We present a case of a 38-year-old woman who developed AAC after laparoscopic appendectomy.
Purpose: Hashimoto's thyroiditis (HT) is an important cause of hypothyroidism caused by autoimmune chronic lymphocytic thyroiditis. In order to attain a better understanding for use in treatment of papillary thyroid carcinoma (PTC) coexisting with HT, we conducted an analysis of the clinicopathologic features, as well as the importance of HT as a prognostic factor. Methods: In this retrospective study, we analyzed 341 patients who were histopathologically diagnosed with PTC following surgery. Results: PTC coexisting with HT was observed in 19.6% (67 patients) of all PTC patients. A statistically significant gender difference was observed in the group with HT (two male vs. 65 female), with a higher positive rate of anti-thyroglobulin antibody and smaller tumor size, compared to the PTC group without HT. When tumor size increased, a lower coexistence rate of HT was observed. No significant differences were observed in multifocality, cervical lymph node (LN) metastasis, coexistence of benign nodule, and extent of LN dissection. However, frequency of extrathyroidal extension was significantly lower and total thyroidectomy rate was higher in the group with HT. TNM stage and AMES stage were similar in both groups; frequency of high MACIS score showed a significant decrease in the group with HT. The recurrence rate and disease-free survival in patients with PTC were not significantly affected by coexistence of HT. Conclusion: We found a significant relationship with gender, extrathyroidal extension, and tumor size in PTC coexisting with HT. However, no significant differences in recurrence rate and disease-free survival were observed between groups. Therefore, coexistence in PTC could not be applicable as a prognostic factor of PTC.
