Laparoscopic herniorrhaphy for inguinal hernia with thanatophoric dysplasia: A case report.

Thanatophoric dysplasia (TD) is a rare and severe type of skeletal dysplasia. Typical clinical findings include macrocephaly, shortening of the four limbs, underdeveloped lungs, and thoracic hypoplasia. Neonates with TD develop severe respiratory problems due to thoracic hypoplasia and require respiratory management for survival. Despite the resolution of respiratory problems, long-term survival cases are rare. Previous studies have reported that surgical procedures in patients with TD are limited to those necessary for survival, including tracheostomy, laminectomy, and ventricular shunt. A 1-year-old boy with TD was treated with laparoscopic herniorrhaphy. To the best of our knowledge, this is the first report of TD treated with laparoscopic procedure.

The outcome of closure of inguinal hernia with laparoscopic percutaneous extraperitoneal closure in young adults.

BACKGROUND: Hernioplasty is one of the most commonly performed surgeries. However, the optimal procedure for young adults has not been defined yet. Our study compared the outcomes of laparoscopic percutaneous extraperitoneal closure (LPEC) in young adults with outcomes in children. MATERIAL AND METHODS: We retrospectively reviewed patients aged 0-30 years who underwent LPEC. Data regarding age, sex, hernia type, surgical time, pre-intraoperative laterality, contralateral patent processus vaginalis (CPPV), and complications were analyzed. RESULTS: LPEC was performed on 2642 patients in our hospital. Of these, 51 patients were young adults (aged 15-30 years). Asymptomatic CPPV in unilateral patients was frequent in the <15-year age group (50.2%) compared to the 15-30-year age group (15.9%). The median surgical time was shorter in the <15-year age group (19 min, interquartile range [IQR]: 24-33) compared to that of the 15-30-year age group (33 min, IQR: 23.3-40.8). CONCLUSIONS: This is the first report on the outcomes in young adult patients who underwent LPEC. The median surgical time was longer in the 15-30-year age group than in the <15-year age group. The median follow-up was 4.7 years with no intra-postoperative complications, such as postoperative bleeding, infection, persistent pain, and recurrence. LPEC is an effective, cosmetic, and safe surgical treatment in young adults and children.

High intestinal vascular permeability in a murine model for Hirschsprung's disease: implications for postoperative Hirschsprung-associated enterocolitis.

PURPOSE: Intestinal vascular permeability (VP) in a murine model for Hirschsprung's disease (HD) and postoperative Hirschsprung-associated enterocolitis (HAEC) were investigated. METHODS: Intestinal VP was determined using a Miles assay using 1% Evans blue injected into a superficial temporal vein of newborn endothelin receptor-B KO HD model (KO) and syngeneic wild-type (WT) mice (n = 5, respectively). Extravasated Evans blue in normoganglionic ileum (Ng-I), normoganglionic proximal colon (Ng-PC) and aganglionic distal colon (Ag-DC) was quantified by absorbance at 620 nm. Quantitative polymerase chain reaction (qPCR) for Vascular Endothelial Growth Factor A (VEGF-A), VEGF-B, CDH5, SELE and CD31, and immunofluorescence for CD31 were performed. RESULTS: VP was significantly higher in Ng-I, Ng-PC, and Ag-DC from KO than WT (p < 0.01, p < 0.05, and p < 0.05, respectively). qPCR demonstrated upregulated VEGF-A in Ng-I and Ag-DC, VEGF-B in Ng-I, and SELE in Ng-I and Ng-PC (p < 0.05, p < 0.05, p < 0.05, p < 0.01 and p < 0.05, respectively), and downregulated CDH5 in Ng-I and Ng-PC from KO (p < 0.05, respectively). Expression of CD31 mRNA in Ng-I and Ag-DC from KO was significantly higher on qPCR (p < 0.05) but differences on immunofluorescence were not significant. CONCLUSIONS: VP may be etiologic for postoperative HAEC throughout the intestinal tract even after excision of aganglionic bowel.
