Metabolic surgery (MS) is a surgery that focuses on improving obesity-related comorbidities.It is often referred to as “diabetic surgery” because of its focus on treating type 2 diabetes. MS is distinguished from bariatric surgery (BS), in which weight loss is the primary goal. However, from a broader perspective, all surgeries for obese patients with diabetes can be considered MS. In Korea, metabolic and bariatric surgery (MBS) has been covered by the national health insurance since 2019. Patients with a body mass index (BMI) ≥35 or those with a BMI ≥30 and obesity-related comorbidities were eligible for MBS. Simultaneously, MS for patients with BMI values between 27.5 and 30 was partly reimbursed. The two major metabolic surgeries are Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). According to the registry of the Korean Society of Metabolic and Bariatric Surgery, 1,560 metabolic surgeries for obese patients with diabetes were performed between 2019 and 2021 in Korea, which was approximately 35.6% of all bariatric surgeries. SG was the most common, followed by RYGB and duodenal switch surgery. When dividing the patients with diabetes who underwent MBS into two groups, specifically those with BMI <35 and ≥35, we found that SG was performed most common procedure in both groups. However, there was a higher proportion of RYGB and duodenal switch operation in the former, indicating a difference in surgical methods between the two groups. MS is a promising tool for the management of poorly controlled diabetes. More data are needed to establish proper patient selection and choice of surgical type.

OBJECTIVES: The purpose of this study is to investigate the Korean adolescent attachment patterns and their relations to parenting behaviors. METHODS: The subjects of this study were 792 high school students in Seoul. We assessed parenting behaviors perceived by adolescents and attachment type and quality of using Parenting Behavior Inventory, Self-report Attachment Style and Revised Adult Attachment Scale. RESULTS: 1) On the attachment pattern of adolescent, it revealed that 47.6% of the subjects were classified as "secure", 32.2% as "preoccupied", 14.6% as "dismissing" and 5.6% as "fearful". 2) The parental neglect was related to fearful and preoccupied patterns and parental inconsistency was related to preoccupied pattern. In terms of attachment quality and parental behavior, more parental affection and reasoning were related with more reliance. And more affection and less intrusiveness, neglect, and inconsistency were related with more closeness. More affection and reasoning and less physical abuse, intrusivenes, over-expectation, neglect, inconsistency were related with less anxiety. CONCLUSIONS: This study shows that adolescent attachment pattern would be transitional compared with that of infancy and adult. More positive parenting behavior such as affection and reasoning, and less negative parenting behavior such as physical abuse, intrusiveness, neglect, inconsistency were related with secure attachment pattern. Also, less positive parenting behavior such as affection and reasoning, and more negative parenting behavior such as physical abuse, intrusiveness, neglect, inconsistency were related with insecure attachment patterns.

The enhanced recovery after surgery (ERAS) program is now widely applied in bariatric surgeries and other surgical procedures. The ERAS program in bariatric surgery consists of various components similar to that in colorectal surgery or other procedures. The major concept of the ERAS protocol relies on a multidisciplinary and multimodal approach to resolve various problems after surgical treatment. The key principles of the ERAS program in bariatric surgery include patient education, opioid-sparing multimodal pain management, prophylaxis of postoperative nausea and vomiting, goal-directed fluid therapy, and minimizing insulin resistance and catabolism. Several guidelines and studies, including randomized clinical trials and systematic reviews, have advocated for the ERAS program in bariatric surgery, which has consistently shown advantages in shortening hospital stay without increasing morbidity. The systematic application of the ERAS program in bariatric patients results in less pain and early recovery and should be routinely recommended.

Advances in genomic processing technology have been applied to the human microbiota and have provided the understanding of the effect of the microbiota in human health and disease. Especially, studies of the gut microbiota have revealed that changes in gut microbiota are related to obesity and the metabolic syndrome. With weight gain, there is an increase in the ratio of Firmicutes to Bacteroidetes. Certain bacteria have increased the ability to ferment dietary substrates, thereby increasing hosts' energy intake and weight gain. After transplantation of microbiota from lean donors, insulin sensitivity of recipients increased along with proliferation of butyrate-producing intestinal microbiota. One important finding after Roux-en-Y gastric bypass is the relative overabundance of Proteobacteria, which is different with the changes seen in weight loss without bypass surgery. Due to the change of microbiota's composition after bypass surgery, the gut environment is changed to unfavorable for energy absorption including decrease of polysaccharide fermentation. Therefore this change may contribute to the improvement of insulin resistance and loss of body weight. According to these results, modifying the gut microbiota through diet, probiotics, fecal transplants, and surgery might be included as therapeutic options for the diseases linked to imbalance in the microbiota.

PURPOSE: Despite recent advances in the surgical and postoperative management of infants with congenital heart disease, nutritional support for this population is often suboptimal. The purpose of this study was to develop a nutritional program for the postoperative period for infants who have had cardiac surgery and to evaluate effects of the program. METHODS: A quasi-experimental design with pretest and posttest measures was used. A newly developed nutritional program including a feeding protocol and feeding flow was provided to the study group (n=19) and usual feeding care to the control group (n=19). The effects of the feeding program were analyzed in terms of total feed intake, total calorie intake, gastric residual volume, and frequency of diarrhea. RESULTS: Calorie intake and feeding amount in the study group were significantly increased compared to the control group. However, the two groups showed no significant differences in gastric residual volume and frequency of diarrhea. CONCLUSION: The results indicate that the nutritional program used in the study is an effective nursing intervention program in increasing feeding amount and calorie intake in infants postoperative to cardiac surgery and does not cause feeding-related complications.

PURPOSE: The purpose was to evaluate outcomes according to different operative strategies of type A esophageal atresia (EA). METHODS: All patients who underwent surgery for type A EA between 1980 and 2011 were included. Patients were divided into 2 groups: E-E group included patients who received esophageal end-to-end anastomosis, whereas E-G group included patients who received esophago-gastric tube anastomosis. RESULTS: Twenty-two patients were included. The median gestational age was 37.5 weeks. The median birth weight was 2.5 kg. Twenty-one patients underwent gastrostomy as initial procedures, and one patient underwent primary esophageal end-to-end anastomosis. The median gap between both esophageal ends was six vertebral distance (VD). Seven patients underwent primary anastomosis of the esophagus, and 14 patients underwent gastric replacement. Three patients (13.6%) had anastomotic leakage and 10 patients (45.5%) had anastomotic stenosis. Most of the patients (90.9%) had gastroesophageal reflux, but only two patients required antireflux surgery. The median VD was significantly shorter in E-E group than in E-G group (3 VD vs. 6 VD). Stenosis was significantly more often in E-E group, but there was no significant difference in leakage and reflux symptoms. CONCLUSION: The treatment for type A EA can include E-E anastomosis or E-G anastomosis, depending on the length of the end-to-end interval after performing gastrostomy. Appropriate tension and blood flow in the anastomosis site are essential for preventing postoperative stenosis and leakage, and esophageal replacement with gastric tube is believed to be feasible and safe in cases where excessive tension is present.

BACKGROUND: Patient controlled analgesia (PCA) is now a widely accepted method of postoperative pain control. It usually begins at postanesthetic care unit, but it takes time to achieve satisfactory level. We have studied the differences in the onset of analgesic effects between starting PCA preoperatively and starting PCA postoperatively. METHODS: Forty patients for subtotal gastrectomy were randomized to two groups. In group I, we started PCA at postanesthetic care unit, in group II, PCA was begun immediately after the induction of anesthesia. We visited each patient and measured 10 cm-visual analgue scale (VAS) score at 3, 6, 9, 12 and 15 hours after the end of operation. We also measured the time taken from the end of operation to extubation. RESULTS: There were no differences in VAS score between two groups on 3 hour. But at 6, 9, and 12 hour, VAS score was significantly lower in group II (P < 0.05). On 15 hour there was no difference between two groups again. There was no significant difference in extubation time between two groups. Preemptive analgesia was not observed in group II. CONCLUSIONS: We concluded that starting PCA immediately after induction of anesthesia can achieve effective analgesia more rapidly than starting PCA at postanesthetic care unit. VAS score was lower than 3 after 12 hours after the end of operation in group II and we speculated that starting PCA 15 hours prior to operation would maximize the analgesic effect of PCA because there was approximately three hours time difference between the two groups.

PURPOSE: Prader-Willi syndrome (PWS) is a well-known genetic disorder, and microdeletion on chromosome 15 is the most common causal mechanism. Several previous studies have suggested that various environmental factors might be related to the pathogenesis of microdeletion in PWS. In this study, we investigated birth seasonality in Korean PWS. METHODS: A total of 211 PWS patients born from 1980 to 2014 were diagnosed by methylation polymerase chain reaction at Samsung Medical Center. Of the 211 patients, 138 were born from 2000-2013. Among them, the 74 patients of a deletion group and the 22 patients of a maternal uniparental disomy (UPD) group were compared with general populations born from 2000 using the Walter and Elwood method and cosinor analysis. RESULTS: There was no statistical significance in seasonal variation in births of the total 211 patients with PWS (chi2=7.2522, P=0.2982). However, a significant difference was found in the monthly variation between PWS with the deletion group and the at-risk general population (P<0.05). In the cosinor model, the peak month of birth for PWS patients in the deletion group was January, while the nadir occurred in July, with statistical significance (amplitude=0.23, phase=1.2, low point=7.2). The UPD group showed the peak birth month in spring; however, this result was not statistically significant (chi2=3.39, P=0.1836). CONCLUSION: Correlation with birth seasonality was identified in a deletion group of Korean PWS patients. Further studies are required to identify the mechanism related to seasonal effects of environmental factors on microdeletion on chromosome 15.

The Peutz-Jeghers syndrome, characterized by mucocutaneous pigmentation and gastrointestinal polyposis, appeares to be transmitted in an autosomal dominant fashion. This syndrome is clinically important because of complications caused by gastrointestinal polyps, such as abdominal pain, gastrointestinal bleeding and intussusception often leading to intestinal obstruction. The possibility of malignany change in the polyp has been a controversial issue. The hamatomatous polyps is not regarded to be premalignanct lesion, generally. But in patients with this syndrome, increased rates of both intestinal and extraintestinal malignancies has been reported. This report is concerned with our experience with a case of 46-year old male patients with Peutz-Jeghers syndrome who had an metastatic adenocarcinoma with unknown primary origin.

OBJECTIVE: Upper-body fat distribution, hyperhomocysteinemia and a depletion in antioxidant status are considered risk factors for atherosclerosis and these factors are related to alcohol consumption and cigarette smoking. The purpose of this study was to determine the influence of alcohol consumption and smoking habits on cardiovascular risk factors in healthy men by using a cross-sectional design. METHODS: Smokers were defined as heavy smokers when they smoked more than 15 cigarettes per day. Group subdivision of drinkers were none, moderate (10-25g alcohol/d) and heavy(>25g alcohol/d) alcohol consumption. Subjects were divided into 6 groups: nondrinker-nonsmoker(n=33), nondrinker-heavy smoker (n=11), moderate drinker-nonsmoker (n=46), moderate drinker- heavy smoker(n=33), heavy drinker-nonsmoker (n=14) and heavy drinker-heavy smoker(n=15). Adipose tissue and muscle areas were calculated from computed tomography scans made at four body levels, first and forth lumbar vertebrae, mid portion of thigh and calf. Fasting serum levels of lipids, proteins, hormones and antioxidants and plasma level of homocysteine were determined. RESULTS: Heavy drinker-heavy smokers showed similar intake of daily calorie and protein to other groups and 65% of them supplemented their diet with synthetic vitamin preparation. Heavy drinker-nonsmokers(36g/d) consumed nearly twice as much alcohol as moderate drinkers(16-18g/d) and heavy drinker-heavy smokers (53g/d) nearly three times as much. In comparison with non and moderate drinker-heavy smokers, heavy drinker-heavy smokers smoked more cigarettes(19 vs 26 cigarettes/d, p<0.05). Although there were no differences among 6 groups in means of age, body mass index, blood pressure and serum GOT and GPT levels, heavy drinkers showed the highest mean value of waist to hip ratio and subcutaneous fat area at first and forth lumbar vertebrae. Heavy drinker-heavy smokers showed higher serum levels of triglyceride and HDL-cholesterol but lower serum levels of transferrin and IGF-1, compared with nondrinkers. Plasma homocysteine level was higher in heavy drinker-heavy smokers than in nondrinker- nonsmokers. Serum levels of beta-carotene, cryptoxanthin and lycopene in heavy smokers or heavy drinkers showed a decrease by about 50% of those in men who did not drink and smoke and these levels were the lowest in heavy drinker-heavy smokers among 6 groups. CONCLUSION: Our results show that heavy alcohol consumption can result in abdominal obesity, hypertriglyceridemia and a decrease in serum carotenoid levels, even though it can cause an increase in HDL-cholesterol level. In addition, a further decrease in serum carotenoids and an increase in plasma homocysteine level in heavy drinker-heavy smokers indicate the increased risk for atherosclerosis in the simultaneous heavy consumption of alcohol and cigarette.
