소아에서 발생한 장중첩증에서 수술적 치료의 필요와 관련된 위험인자

The aim of this study was to identify the risk factor related to the need for operative treatment and avoid unnecessary non-operative management for intussusception in children. We retrospectively reviewed medical records of patient treated for intussusception at our institution between January 2006 and January 2013. Clinical features such as gender, age, seasonal variation, symptoms and signs, treatment results were analyzed. Univariate and multivariate analyses including a chi-square test for categorical variables and logistic regression analysis were performed. During the study period, 356 patients were treated for intussusception. 328 (92.1%) was treated successfully by the non-operative pneumoreduction, and 28 (7.9%) required operative management. On univariate analysis, risk factors which were related to the need for operative treatment were age, vomiting, bloody stool, lethargy, and symptoms duration. A logistic regression analysis in order to assess for independent predictors of operative treatment was performed. Age (<6 vs ${\geq}12$ months) (OR 4.713, 95% CI 1.198~18.539, p=0.027) and symptoms duration longer than 48 hours (OR 4.534, 95% CI 1.846~11.137, p=0.001) were significantly associated with a requirement for operative treatment. We conclude that younger age and a longer duration of symptoms (${\geq}48$ hours) are the independent risk factor related to the need for operative treatment for intussusception. Early surgical intervention or transfer to a hospital with pediatric surgical capabilities should be considered for patients with these findings.

Following liver transplantation, a few reports have documented hepatic venous outflow obstruction (HVOO) after inferior vena cava (IVC) stenting for the treatment of IVC stenosis. However, HVOO occurred early after IVC stenting and was mostly associated with living donor liver transplantation. Here, we report a case of HVOO that occurred 31 months after IVC stenting in a man who received deceased donor liver transplantation (DDLT) using a modified piggyback (PB) technique. The cause of HVOO was unclear, but one possible explanation is that the balloon-expandable IVC stent might have compressed the IVC chamber on the donor liver side, which would have changed the outflow hemodynamics, resulting in intimal hyperplasia. Therefore, simultaneous hepatic venous stenting with IVC stent placement could help prevent HVOO in patients receiving DDLT with the modified PB technique

A Single Center Experience for a Feasibility of Totally Laparoscopic Living Donor Right Hepatectomy
이수경,한영석,하헌탁,한자령,천재민 대한내시경복강경외과학회 2019 Journal of Minimally Invasive Surgery Vol.22 No.2
Purpose: Donor safety is the most important problem of living donor liver transplantation (LDLT). Although laparoscopic liver resection has gained popularity with increased surgical experience and the development of laparoscopes and specialized instruments, a totally laparoscopic living donor right hepatectomy (LDRH) technique has not been investigated for efficacy and feasibility. We describe the experiences and outcomes associated with LDRH in adult-to-adult LDLT in order to assess the safety of the totally laparoscopic technique in donors. Methods: Between May 2016 and July 2017, we performed hepatectomies in 22 living donors using a totally laparoscopic approach. Among them, 20 donors underwent LDRH. We retrospectively reviewed the medical records to ascertain donor safety and the reproducibility of LDRH; intra-operative and post-operative results including complications were demonstrated after performing LDRH. Results: The median donor age was 29 years old and the median body mass index was 22.6 kg/m2. The actual graft weight was 710 g and graft weight/body weight (GRWR) was 1.125. No donors required blood transfusion, conversion to open surgery, or reoperation. The postoperative mortality was nil and postoperative complications were identified in two donors. One had fluid collection in the supra-pubic incision site for graft retrieval and the second had a minor bile leakage from the cutting edge of the right hepatic duct stump. All the liver function tests returned to normal ranges within one month. Conclusion: LDRH is a feasible operation owing to low blood loss and few complications. However, LDRH can be initially attempted after attaining sufficient experience in laparoscopic hepatectomy and LDLT techniques.
