Successful outcome with oral sirolimus treatment for complicated lymphatic malformations: a retrospective multicenter cohort study

Purpose@#Sirolimus has emerged as a safe and effective treatment for complicated lymphatic malformations (LMs). We aim to prove the effectiveness and safety of sirolimus as a therapeutic option for patients with complicated LMs. Methods: Fifty-eight patients with complicated LMs treated with sirolimus for at least 6 months at multicenter between July 2018 and January 2023 were enrolled. All patients were administered oral sirolimus starting at 0.8 mg/m 2 every 12 hours, with target serum concentration levels of 8–15 ng/mL. Evaluation for clinical symptoms and LMs volume on MRI were reviewed to assess treatment response and toxicities. Evaluation of disease response was divided into 3 values:complete response, partial response (significant, moderate, and modest), and progressive disease. @*Results@#The median age at the initiation of sirolimus treatment was 6.0 years (range, 1 month–26.7 years). The median duration of treatment was 2.0 years (range, 6 months–4.4 years). The most common lesions were head and neck (25 of 58, 43.1%). Forty-six patients (79.3%) demonstrated a reduction in LMs volume on MRI or improvement of clinical symptoms including 2 complete responses. The young age group and the patients who underwent few prior therapies showed better responses. None of the patients had toxicities attributable to sirolimus with a Common Terminology Criteria for Adverse Events grade of ≥3. @*Conclusion@#Oral sirolimus treatment brought a successful outcome without severe adverse effects. It could be the firstline therapy, especially for the young age group of complicated LMs, and an additional option for refractory lesions that did not respond to conventional treatment.

Clinical characteristics and treatment outcomes of symptomatic Meckel diverticulum: a comparative study among children, adolescent, and adult patients

Purpose@#We investigated the clinical characteristics and treatment outcomes of symptomatic Meckel diverticulum (MD) in adolescents by comparison with children and adults. @*Methods@#We retrospectively reviewed the medical records of patients who underwent symptomatic MD surgery from January 2002 to December 2019. Demographic information, clinical presentations, preoperative evaluations, operative variables, postoperative outcomes, and pathologic findings were collected. We performed analyses by dividing all patients into three groups according to age at surgery: child group (<10 years), adolescent group (10–19 years), and adult group (≥20 years). @*Results@#Forty-three patients underwent symptomatic MD surgery (the child group, 14; the adolescent group, 17; and the adult group, 12). Vomiting and intestinal obstruction decreased significantly with age (P = 0.042 and 0.001), whereas hematochezia and gastrointestinal bleeding showed an increasing trend with age, although not statistically significant (P = 0.064 and 0.064). Ultrasound performance decreased significantly with age (P = 0.002), whereas CT performance showed an increasing trend with age, although not statistically significant (P = 0.193). Preoperative diagnosis rate increased significantly with age (P = 0.029). Laparoscopic surgery was performed significantly more in the adult group than in other groups (P = 0.001). The sizes of MD were significantly greater in the adolescent group than in other groups (P = 0.006 and 0.002). @*Conclusion@#The clinical characteristics and treatment outcomes of symptomatic MD in adolescents exhibit a transitional pattern between children and adults. Therefore, it is important for clinicians to recognize that adolescent patients with symptomatic MD have the characteristics of both children and adult patients to ensure optimal care.

Optimal timing for inguinal hernia repair in premature infants: surgical issues for inguinal hernia in premature infants

Purpose@#We analyzed the timing of inguinal hernia repair in premature infants in the neonatal intensive care unit (NICU) considering recurrence, incarceration, and other complications. @*Methods@#In this multicenter retrospective review, premature infants (<37 weeks) in the NICU diagnosed with inguinal hernia between 2017 and 2021 were segregated into 2 groups based on the timing of inguinal hernia repair. @*Results@#Of 149 patients, 109 (73.2%) underwent inguinal hernia repair in the NICU and 40 (26.8%) after discharge. Preoperative incarceration did not differ, but complications with recurrence and postoperative respiratory insufficiency were higher in the NICU group (11.0% vs. 0%, P = 0.029; 22.0% vs. 5.0%, P = 0.01). Multivariate analysis showed that the significant factors affecting recurrence were preoperative ventilator dependence and body weight of <3,000 g at the time of surgery (odds ratio [OR], 16.89; 95% confidence interval [CI], 3.45–82.69; P < 0.01 and OR, 9.97; 95% CI, 1.03–95.92; P = 0.04). @*Conclusion@#Our results suggest that when premature infants are diagnosed with inguinal hernia in the NICU, inguinal hernia repair after discharge may decrease the odds of recurrence and postoperative respiratory insufficiency. In patients who have difficulty delaying surgery, it is thought that surgery should be performed carefully in a ventilator preoperatively or weighed <3,000 g at the time of surgery.

Intussusception in Neonates: Clinical Characteristics of Eight Cases in a Single Center

Purpose@#Intussusception is the most common cause of bowel obstruction in children; however, it is rarely diagnosed in newborn infants. This study aimed to describe the clinical features of intussusception in newborn infants. @*Methods@#Medical records of eight patients diagnosed with intussusception during the newborn period at Ulsan University Hospital between March 2007 and March 2020 were retrospectively reviewed. @*Results@#Among the eight cases, two occurred in the intrauterine period and six occurred in the postnatal period. Intrauterine intussusception presented with symptoms of bowel obstruction within 1 to 2 days after birth, and ileal atresia was diagnosed simultaneously through exploratory laparotomy. All the postnatal patients were extremely low birth weight infants (median gestational age and birth weight: 25+6 weeks and 745 g, respectively). Four cases were diagnosed preoperatively using abdominal ultrasonography. One patient was diagnosed by exploratory laparotomy because the clinical symptoms were nonspecific and difficult to differentiate from those of necrotizing enterocolitis, a more prevalent complication in preterm infants. The site of intussusception in all six patients was the small bowel. Meckel’s diverticulum (one case) and meconium obstruction (two cases) were found to be the lead point. @*Conclusion@#Neonatal intussusception tends to show different clinical features according to its period of occurrence. Intussusception, especially in preterm infants, has nonspecific clinical features; therefore, clinicians should always be cautious of this disease for its early diagnosis.

Rapidly growing pediatric trampoline-related injuries in Korea: a 10-year single center retrospective study / 소아과

PURPOSE: Several published policy statements have warned against the risks associated with trampoline use and recommended safety guidelines. However, few studies have focused on trampoline-related injuries in Korea. This study aimed to assess the incidence and characteristics of pediatric trampoline-related injuries presented to Ulsan University Hospital. METHODS: We retrospectively reviewed the medical records of children aged <16 years with trampoline-related injuries who visited our Emergency Department between 2008 and 2017. RESULTS: Over the 10-year period, 178 trampoline-related injuries were reported, which represented a significant increase (P=0.016). Most (87.6%) of the injuries occurred during the last 5 study years, and a rapid increase in injuries was observed in children aged <6 years. Lower extremity injuries (62.4%) were the most common, followed by injuries of the upper extremities, head and face, and trunk, including injuries to the neck and spine. Sixty-seven children (37.6%) had fractures, and proximal tibia fractures were the most common. Fractures were significantly more common in younger children (<6 years old) than in older children (P=0.026). CONCLUSION: In Korea, the mechanism of trampoline injury is similar to that of injuries incurred in indoor trampoline parks but is characterized by smaller spaces and multiple users. Trampoline use and the incidence of trampoline-related injuries in children aged <6 years are increasing rapidly. Prohibiting the use of trampolines for children aged <6 years, restricting simultaneous use by multiple children, and ensuring adult supervision should be strictly emphasized. Public awareness and policy guidelines are needed to reduce the incidence of trampoline-related injuries.

Use of Omega-3 Polyunsaturated Fatty Acids to Treat Inspissated Bile Syndrome: A Case Report / 대한소아소화기영양학회지

Inspissated bile syndrome (IBS) is a rare condition in which thick intraluminal bile, including bile plugs, sludge, or stones, blocks the extrahepatic bile ducts in an infant. A 5-week-old female infant was admitted for evaluation of jaundice and acholic stool. Diagnostic tests, including ultrasound sonography, magnetic resonance cholangiopancreatography, and a hepatobiliary scan, were not conclusive. Although the diagnosis was unclear, the clinical and laboratory findings improved gradually on administration of urodeoxycholic acid and lipid emulsion containing omega-3 polyunsaturated fatty acids (PUFAs) for 3 weeks. However, a liver biopsy was suggestive of biliary atresia. This finding forced us to perform intraoperative cholangiography, which revealed a patent common bile duct with impacted thick bile. We performed normal saline irrigation and the symptom was improved, the final diagnosis was IBS. Thus, we herein report that IBS can be treated with omega-3 PUFAs as an alternative to surgical intervention.

Validity of breast-specific gamma imaging for Breast Imaging Reporting and Data System 4 lesions on mammography and/or ultrasound

PURPOSE: The purpose of this study was to assess the breast-specific gamma imaging (BSGI) in Breast Imaging Reporting and Data System (BI-RADS) 4 lesions on mammography and/or ultrasound. METHODS: We performed a retrospective review of 162 patients who underwent BSGI in BI-RADS 4 lesions on mammography and/or ultrasound. RESULTS: Of the 162 breast lesions, 66 were malignant tumors and 96 were benign tumors. Sensitivity and specificity of BSGI were 90.9% and 78.1%, and positive predictive value and negative predictive value were 74.1% and 92.6%. The sensitivity or specificity of mammography and ultrasound were 74.2% and 56.3% and 87.9% and 19.8%, respectively. The sensitivity and specificity of BSGI for breast lesions ≤1 cm were 88.0% and 86.8%, while the values of beast lesions >1 cm were 92.7% and 61.5%. The sensitivity or specificity of BSGI and mammography for patients with dense breasts were 92.0% and 81.3% and 72.0% and 50.0%, respectively. 26 patients showed neither a nodule nor microcalcification on ultrasound, but showed suspicious calcification on mammography. The sensitivity and specificity of BSGI with microcalcification only lesion were 75.0% and 94.4%. CONCLUSION: This study demonstrated that BSGI had shown high sensitivity and specificity, as well as positive and negative predictive values in BI-RADS 4 lesions on ultrasound and/or mammography. BSGI showed excellent results in dense breasts, in lesions that are less than 1 cm in size and lesions with suspicious microcalcification only.

An idiopathic gigantomastia

Gigantomastia is a rare condition characterized by excessive breast growth. It has been reported that the majority of gigantomastia cases occur during either pregnancy or puberty. We were presented with a rare case of gigantomastia associated with neither pregnancy nor puberty, and successfully treated it with reduction mammaplasty and free nipple graft. This idiopathic gigantomastia is the very first case in Korea, and adds to the worldwide total of 9 reported cases.

A comparative analysis of endoscopic thyroidectomy versus conventional thyroidectomy in clinically lymph node negative thyroid cancer

PURPOSE: Differentiated thyroid cancer has a good prognosis and high incidence in young women. Since endoscopic techniques were first recorded in 1996, surgical indications of endoscopic thyroidectomy have broadened. Therefore, the aim of this study is to investigate the usefulness of endoscopic thyroidectomy in clinically lymph node negative (cN0) thyroid cancer patients, based on oncologic completeness and safety, considering cosmetic outcomes. METHODS: From July 2009 to June 2011, a total of 166 cases had undergone endoscopic thyroidectomy using the BABA (bilateral axillo-breast approach) method or conventional open thyroidectomy by one surgeon. Finally, excluding 72 patients, 94 patients with cN0 thyroid cancer were divided into two groups according to operative methods and analyzed to compare differences between the two methods retrospectively (endoscopic group, n = 49; conventional open group, n = 45). RESULTS: We practiced comparative analysis for clinicopathologic characteristics, surgical outcomes including postoperative complications, and recurred cases during follow-up periods of each group. The results showed there was a tendency for patients, young, women rather than men, and having small size of thyroid cancer, to prefer endoscopic surgery to open surgery. Meanwhile, in postoperative complications, there were no statistically significant differences. During short follow-up periods, no recurrence or mortality case was observed. CONCLUSION: Endoscopic thyroidectomy is a feasible and safe method for the treatment of clinically lymph node negative (cN0) thyroid cancer.

A Comparative Analysis of Endoscopic Versus Conventional Open Thyroidectomy in the Treatment of Papillary Thyroid Cancer According to Preoperative Risk Stratification / 대한내분비외과학회지

PURPOSE: It is well known that papillary thyroid cancer (PTC) has a good prognosis and high incidence in young women. The objective of the study was to review our criteria to select surgical modality and surgical results and to confirm the feasibility of endoscopic thyroidectomy according to the preoperative risk stratification in the treatment of papillary thyroid cancer. METHODS: Between May 2009 and April 2012, 197 patients underwent either a conventional open or an endoscopic thyroidectomy with the preoperative consideration of risk group using clinical parameters of AMES system (patient age, size of tumor, extrathyroid extension, and presence of distant metastasis). A retrospective analysis of the pathologic data according to AMES system after surgery was also conducted. The endoscopic thyroidectomy was performed using the BABA (bilateral axillo-breast approach) method. RESULTS: Based on the method of operation, the low-risk group patients (n=197) were divided into two groups: endoscopic group (n=78) and open group (n=119). Procedure time, postoperative complication rates, and length of hospital stay were tracked, albeit these were not significantly different between the two groups. From the pathologic findings, it was reported that there were no significant differences in tumor size, extrathyroid extension, and metastasis and also in the Off T4 – thyroglobulin level between the two groups. CONCLUSION: Endoscopic thyroidectomy is a feasible method for the treatment of selected cases of thyroid cancer such as low-risk group according to the appropriate preoperative risk stratification.

Adrenocortical tumors in children 18 years old and younger / 대한외과학회지

PURPOSE: Pediatric adrenocortical tumors (ACTs) are rare. We reviewed findings in 8 children, 18 years of age or younger, diagnosed with ACT in our institution over the past 15 years. METHODS: We retrospectively reviewed 8 children with ACTs treated between 1996 and 2010. RESULTS: Three girls and 5 boys were treated for ACTs; their median age at presentation was 144 months (range, 28 months to 18 years). Seven patients showed signs of endocrine dysfunction, 4 with Cushing syndrome, 2 with virilization, and 1 with hyperaldosteronism. One patient, with symptoms of hematuria, underwent a computed tomography scan, which showed an adrenal mass. The median duration of symptoms prior to resection was 6 months (range, 1 to 24 months). Five patients had adenomas and 3 had carcinomas. All underwent complete resection of the tumor, with laparoscopic adrenalectomy performed on 3 patients with adenoma and 1 with carcinoma. The median tumor weight was 12.5 g (range, 1 to 130 g) and the median tumor volume was 18.3 cm3 (range, 2.2 to 299.2 cm3). At a median follow-up of 5.1 years (range, 4 months to 15 years), all 8 patients remain alive with no recurrence of disease. CONCLUSION: The characteristics of pediatric ACTs vary considerably. Laboratory findings, clinical hormonal features, and tumor size could not distinguish adenomas from carcinomas before surgery. Complete tumor resection was successful, with no tumor recurrence. However, the small number of patients and short follow-up period limit assessments of prognosis.

Single Port Laparoscopic Appendectomy in Pediatric Patients: A Preliminary Experience

PURPOSE: The authors retrospectively compared single-port laparoscopic appendectomy (SPLA) with conventional laparoscopic appendectomy (CLA) in terms of the perioperative outcomes in pediatric patients. METHODS: Cases of laparoscopic appendectomy between December 2009 and July 2010 were retrospectively reviewed. The demographic data, operating time, pathology of the appendix, hospital stay and surgical morbidities were compared. RESULTS: Ten patients underwent SPLA and 57 underwent CLA. The mean age of the CLA and SPLA groups were 11.2 and 10.6 years, respectively. The pathology of the appendix showed that relatively more severe cases were included in the CLA group. There were 2 cases of a post operative intra-abdominal abscess and 2 cases of an umbilical wound infection in the SPLA group. Therefore, the SPLA group showed a significantly higher surgical morbidity rate (p=0.003) and hospital stay (p=0.05). The mean operation time of the SPLA and CLA group was 88.1+/-30.1 and 71.6+/-26.3 minutes, respectively; the mean operation time of the SPLA group was slightly longer (p=0.054). On the other hand, surgical morbidity and the mean operation time showed a decreasing tendency in the latter half of 10 cases. CONCLUSION: The initial experience of SPLA in pediatric patients shows a higher complication rate and longer hospital stay than CLA. On the other hand, the complication rates and operation time have been decreasing. The clinical outcomes are expected to improve after going through a learning curve.

Operative Management of Complicated Meckel's Diverticulum Laparotomy and versus Laparoscopic Assisted Surgery

Meckel's diverticulum (MD) has various clinical presentations and due to the limitation of imaging studies, pre-operative diagnosis is a challenge in pediatric patients. Recently, laparoscopic exploration has been suggested as a favorable method for the diagnosis and treatment of complicated MD. We investigated the results of laparoscopic-assisted surgery compared with open technique. We retrospectively studied patients who underwent resection of complicated MD at our institute from 1997 to 2010 and compared 11 treated by laparoscopic-assisted diverticulectomy (LD) with 11 treated by open diverticulectomy (OD) for complicated MD. Operation time was not significantly different in the two groups. Hospital stay and time to diet were not significantly different. Two patients were re-admitted due to mechanical ileus in the LD group. None of patients in either group needed re-operation. Considering the possibility of false-positive results with imaging studies and the cosmetic benefit, laparoscopic-assisted surgery is a safe and effective treatment modality to diagnose and treat complicated Meckel's diverticulum.

Clinical experience with persistent cloaca / 대한외과학회지

PURPOSE: Persistent cloaca is one of the most severe types of anorectal malformation. Appropriate initial drainage is difficult due to their various malformations and hydrocolpos or dilated urinary bladder. Corrective surgery also differs among individual patients. We describe our experiences with the surgical management of children with persistent cloaca. METHODS: We retrospectively reviewed 16 children diagnosed with persistent cloaca at Asan Medical Center. RESULTS: Sixteen patients were managed in their neonatal period. Twelve patients had enlarged bladder or vagina at birth. Three patients, who did not undergo cystostomy or vaginostomy at first operation, had earlier complications after surgery or required drainage tube insertion. One patient who did not undergo hydrocolpos drainage died of sepsis and complications. Nine patients underwent corrective surgery; posterior sagittal anorectovaginourethroplasty using the Pena method. Three patients required additional operations due to complications after surgery. CONCLUSION: Patients found to have anatomical malformations before colostomy, as well as hydrocolpos and bladder enlargement, require a vaginostomy with or without a cystostomy to reduce complications. Follow-up is required in patients with hydrocolpos and bladder enlargement to determine whether vaginal drainage improves dilated bladder. Continuous long-term follow-up examination is required to determine the long-term results of corrective surgery.

Extracorporeal Membrane Oxygenation in Neonates with Congenital Diaphragmatic Hernia: a Preliminary Experience

Extracorporeal membrane oxygenation (ECMO) has been utilized in congenital diaphragmatic hernia (CDH) patients with severe respiratory failure unresponsive to conventional medical treatment. We retrospectively reviewed 12 CDH patients who were treated using ECMO in our center between April 2008 and February 2011. The pre ECMO and on ECMO variables analyzed included gestational age, sex, birth weight, age at the time of ECMO cannulation, arterial blood gas analysis results, CDH location, timing of CDH repair operation, complications and survival. There were 9 boys and 3 girls. All patients were prenatally diagnosed. Mean gestational age was 38.8 +/- 1.7 weeks and mean birth weight was 3031 +/- 499 gram. Mean age at the time of ECMO cannulation was 29.9 +/- 28.9 hours. There were 4 patients who survived. Survivors showed higher 5 min Apgar scores (8.25 +/- 0.96 vs. 7.00 +/- 1.20, p=0.109), higher pre ECMO mean pH (7.258 +/- 0.830 vs. 7.159 +/- 0.986, p=0.073) and lower pre ECMO PaCO2 (48.2 +/- 7.9 vs. 64.8 +/- 16.1, p=0.109) without statistical significance. The hernia was located on the left side in 10 patients and the right side in 2 patients. The time interval from ECMO placement to operative repair was about 3~4 days in 5 early cases and around 24 in the remaining cases. There were 3 cases of post operative bleeding requiring re operation and 2 cases of abdominal compartment syndrome requiring abdominal fascia reopening. ECMO catheter reposition was required in 4 cases. Three cases of arterial or venous thrombosis were detected and improved with follow up. Our data suggests that ECMO therapy could save the lives of some neonates with CDH who can not be maintained on other treatment modalities. Protocolized management and accumulation of case experience might be valuable in improving outcomes for neonates with CDH treated with ECMO.

Clinical Experience of H-type Tracheoesophageal Fistula

Tracheoesophageal fistula without esophageal atresia (H-type TEF) is a congenital anomaly that is characterized by a fistula between the posterior wall of the trachea and the anterior wall of the esophagus, not accompanied by esophageal atresia. The purpose of this study is to investigate the clinical characteristics, diagnostic time, the side of cervical approach and short term result after surgery by searching medical records of patients treated for H-type TEF. The search was done at University of Ulsan, Department of Pediatric Surgery of Asan Medical Center, and the total number of patients from May 1989 to December 2010 was 9 with M:F ratio of 1:2. The median gestational age was 39(+6) (32(+6)~41(+0)) wks. Seven out of nine patients were born at term and the other two were born premature. The clinical presentation was aspiration pneumonia, difficulty in feeding, chronic cough, vomiting, abdominal distension and growth retardation. The symptoms presented right after birth. The diagnosis was made with esophagography and the median time of diagnosis was 52 days of life. The majority of surgical corrections were performed within two weeks of diagnosis (median; 15d, range; 1d - 6m). Six patients had associated anomalies, and cardiac anomalies were most common. The cervical approach was utilized in all cases (right 2, left 7). Transient vocal cord palsy and minor esophageal leakage complicated two cases. Although the diagnosis of H-type TEF was difficult and often delayed, we had a good short term result. The left cervical approach was preferred.

Treatment of Pulmonary Sequestration with Thoracoscopic Approach

Pulmonary sequestration (PS) is a rare congenital malformation of the lower respiratory tract. The anomaly is characterized by absence of communication with the tracheobronchial tree and isolated blood supply from an anomalous systemic vessels. With the utilization of antenatal ultrasound, the diagnosis of asymptomatic neonatal PS has increased. Treatment options include observation, arterial embolization and surgical resection. The aim of the present study is to review the clinical course of PS and to share our experience with thoracoscopic resection. A total of 96 patients with PS were treated at Asan Children's Hospital between 1999 and 2010. The diagnosis of PS was established by CT in the cases managed by observation or embolization, and by tissue pathology in the surgical cases. Medical records and radiographic images were retrospectively reviewed. Thirty-nine patients were managed by embolization and 30 patients by surgery. The remaining 27 patients have been under observation without any procedures. Among 27 observation patients, 1 patient regressed completely and 10 patients were lost to follow up. Of the 39 embolizations patients, 2 had their lesion regress and sepsis was suspected after embolization. In 1 patient, the microcoil migrated to the iliac artery during the embolization procedure, and another patient developed renal abscess caused by renal artery embolization. Among 30 surgical cases, resection by thoracotomy was performed in 27 at the Department of Thoracic Surgery, and thoracoscopic resection in 3 at the Division of Pediatric Sugery. Only one wound complication ocurred. We conclud that surgical excision should be recommended for pulmonary sequestration, whether the sequestration is symptomatic or not because of the risk of infection, the low rate of natural regress, poor compliance, severe complications after embolization, and to exclude other pathology. In summary, thoracoscopic resection of the pulmonary sequestration is feasible, efficacious, safe and cosmetically superior even in neonatal period.
