Pediatric Adenocarcinoma in Korea: A Multicenter Study / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#Adenocarcinoma is an extremely rare malignancy in the pediatric population. Research regarding pediatric adenocarcinoma is very rare in Korea. This study aimed to investigate the clinical features of pediatric adenocarcinomas of various primary organ sites in Korea. @*Materials and Methods@#Pediatric patients under 18 years, diagnosed with adenocarcinoma of various sites between January 1995 and December 2016, were included. We retrospectively reviewed patient and tumor characteristics and calculated survival estimates, reported as 5-year survival rate and 95% confidence interval. @*Results@#Of 80 patients (median age, 15 years; range, 10 to 17 years), 37 (46.3%) were men, and 24 (30%) had a family history of cancer or underlying disease relevant to malignancy. The cancer locations were the colon and rectum (n=32), ovaries (n=18), stomach (n=15), lung (n=4), small bowel (n=1), and other sites (n=10). Totally, 54.8% patients (42/77) had stage 3 or 4 disease. The median follow-up period was 2.0 years (range, 0 to 20.4). The 5-year overall survival estimate for all patients, and for those with stomach, colorectal, ovarian, and other cancer sites were 57.9%±11.5%, 58.2%±25.7%, 41.5%±18.2%, 87.5%±16.2%, and 64.0%±34.4%, respectively. The 5-year survival rate differed significantly between categories of adenocarcinomas into gastrointestinal (GI) (44.7%) and non-GI adenocarcinomas (78.8%) (p=0.007). The 5-year survival rate also differed significantly according to carcinoembryonic antigen level (69.3% in 3 ng/mL; p < 0.001). @*Conclusion@#In pediatric patients, adenocarcinomas arise from various organs and are often diagnosed at advanced stages. Large, prospective studies for their accurate clinical characteristics and prognostic factors are needed.

Santulli Enterostomy: A Considerable Method for Patients Who Require Proximal Enterostomy

PURPOSE: Santulli enterostomy has been used for various surgical abdominal conditions that require temporary diversion of bowel during a neonatal period. The aim of this study was to report clinical outcomes of Santulli enterostomy and to evaluate its usefulness. METHODS: Between January 2000 and December 2016, 40 neonates who underwent Santulli enterostomy were enrolled; Santulli enterostomies were performed for 25 patients without previous laparotomy (primary Santulli group) and 15 patients with previous laparotomy (secondary Santulli group). RESULTS: Small bowel atresia is the first common indication of Santulli enterostomy (22/40, 55.0%), and luminal discrepancy between proximal and distal bowel was the most common determinant factor of Santulli enterostomy (17/40, 42.5%). The median age at surgery and mean birth weight were 2 days and 2,480 g respectively in the primary group, and 71 days, 2,340 g respectively in the secondary group. Operation time was significantly longer in the secondary group than the primary group (156±48 minutes vs. 224±95 minutes, p=0.019), and there was no difference in the time taken to initiation of oral feeding between the two groups. Santulli enterostomy closure was performed at median 65 days after Santulli enterostomy for primary group and 70 days for secondary group. Six complications (15.0%) were found after Santulli enterostomy, and nine complications (24.3%) after Santulli enterostomy closure (p=0.302). The incidence of complications was significantly higher in secondary group than in primary group (4.5% vs. 53.3%, p=0.001), and the reoperation rate was also significantly higher in the secondary group (4.5% vs. 46.7%, p=0.004). CONCLUSION: Santulli enterostomy could be applied as a temporary enterostomy in neonatal patients with various surgical abdominal diseases. Considering the high complication rate after secondary Santulli enterostomy closure, decision making on the timing of enterostomy closure should be done with caution.

Bile Duct Stricture and Intrahepatic Cystic Formation after Abdominal Injury due to Child Abuse: A Case Report

A 6-year-old male who lived with a mother in a single-parent family was referred to the emergency room with multiple traumas. There was no specific finding on CT scan of the other hospital performed 55 days before admission. However, CT scan at the time of admission showed common bile duct (CBD) stenosis, proximal biliary dilatation and bile lake formation at the segment II and III. Endoscopic retrograde biliary drainage was performed, but the tube had slipped off spontaneously 36 days later, and follow-up CT scan showed aggravated proximal biliary dilatation above the stricture site. He underwent excision of the CBD including the stricture site, and the bile duct was reconstructed with Roux-en-Y hepaticojejunostomy. Pathologic report of the resected specimen revealed that the evidence of trauma as a cause of bile duct stricture. While non-iatrogenic extrahepatic biliary trauma is uncommon, a level of suspicion is necessary to identify injuries to the extrahepatic bile duct. The role of the physicians who treat the abused children should encompass being suspicious for potential abdominal injury as well as identifying visible injuries.

Does international study group on pancreatic fistula (ISGPF) classification need modification after distal pancreatectomy?

BACKGROUNDS/AIMS: Few reports have validated the clinical postoperative pancreatic fistula (PF) after distal pancreatectomy. The study intended to validate the predictability for clinical PF of drain amylase and lipase and to find out more appropriate postoperative day (POD) for diagnostic criterion of PF. METHODS: A total of 154 patients underwent distal pancreatectomy. We used the clinical database registry system of the Gangnam Severance Hospital and Severance Hospital, Yonsei University Health System for these analyses. The receiver operating characteristic curve of the drain amylase or lipase concentration on each day was used to predict clinical PF (International Study Group on Pancreatic Fistula [ISGPF] grade B or C) and areas under the curves (AUC) were compared. RESULTS: Amylase and lipase AUC values poorly predicted clinical PF before POD 3 and, gradually increased until POD 5 and became well correlated with clinical PF (ISGPF grade B or C). In contrast, the prediction of clinical PF using drain lipase did not differ from that using drain amylase. The drain amylase concentration on POD 6 was most precisely correlated with clinical PF. CONCLUSIONS: Clinical PF prediction was validated by using drain amylase and lipase concentrations, in which drain amylase assessment at POD 6 appeared to be an appropriate diagnostic criterion of PF after distal pancreatectomy. We suggest some modification of ISGPF definition, especially for distal pancreatectomy.
