ABSTRACT
Objective:To explore the prognosis and treatment experience of fetal/neonatal ovarian cyst.Methods:Clinical data of 35 cases of fetal/neonatal ovarian cyst (38 ovarian cysts) admitted to Guangdong Women and Children Hospital from June 2014 to December 2019 were retrospectively collected, including the cyst size before and after birth, ultrasonic features, intraoperative conditions, and pathology. According to the ultrasonic features at the first prenatal detection, the ovarian cysts were divided into two groups: simple cyst group (25 cysts) and complex cyst group (13 cysts). Two independent samples t-test and Fisher exact test were used to compare the characteristics of cysts between the two groups. The outcomes and treatment experience were summarized. Results:(1) The ratio of intraoperative torsion in the complex cysts group was higher than that in the simple cysts group [10/13 vs 32% (8/25), Fisher exact test, P<0.05]. (2) Twenty-five simple cysts were found on the first prenatal ultrasound scan, and 32% (8/25) of them eventually transformed into complex cysts. Among these eight cysts, the maximum diameter of five cysts was >4 cm before the transformation. (3) Postnatal ultrasound found one cyst regressed spontaneously and among the remaining 37 cysts, simple and complex type cysts were accounted for 16 and 21, respectively. Among the complex type cysts, 90% (19/21) were consistent with prenatal ultrasound. (4) Out of the 21 complicated cysts, 19 were surgically removed; the remaining two cysts (maximum diameter <3 cm) were observed conservatively and disappeared spontaneously within one year. During the operation, 81% (17/21) of the complicated cysts were found with torsion and 24% (5/21) with ovarian loss. Conclusions:Simple cysts can transform into complex cysts, especially the biggest diameter >4 cm. Complex fetal/neonatal ovarian cysts indicated by ultrasonography were more prone to torsion, which required postnatal operation.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the operation timing of newborns with rectosigmoid Hirschsprung's disease (HD).</p><p><b>METHODS</b>From March 2013 to September 2015, 35 newborns diagnosed as rectosigmoid HD in our department were prospectively and randomly divided into 2 groups: less than 3 months treatment group (18 cases) and more than 3 months treatment group (17 cases, conservative treatment for 3 months). They all underwent laparoscopic-assisted transanal endorectal pull-through (LATEP) (modified Soave) procedure. Clinical data, perioperative conditions, postoperative complication, postoperative anal function evaluated by Wingspread score and barium enema were compared between two groups.</p><p><b>RESULTS</b>The baseline data of two groups were comparable (all P>0.05). All the cases completed single-stage LATEP procedure successfully without conversion to open operation. Compared with more than 3 months treatment group, preoperative bowel preparation time and operation time were significantly shorter [(6.2±3.3) vs. (9.3±4.1) days, P=0.042; (95±15) vs.(121±23) minutes, P=0.029, respectively], intra-operative blood loss was significantly less [(13±3) ml vs. (22±5) ml, P=0.036], length of resected bowel was significantly shorter [(16±5) cm vs.(23±8) cm, P=0.033], and bowel movement recovery time, parenteral nutrition time, hospital stay were also significantly shorter [(2.3±0.5) vs. (2.9±0.6) days, P=0.046; (5.1±2.1) vs. (5.9±2.3) days, P=0.048; (12.9±3.3) vs. (15.8±4.3) days, P=0.049, respectively] in less than 3 months treatment group. No short-term complications, such as anastomotic leak, interlayer infection and abdominal infection occurred in both groups. The follow-up period ranged from 2 months to 24 months. Only the incidence of perianal excoriation was significantly higher in less than 3 months treatment group compared with more than 3 months treatment group [50.0%(9/18) vs. 23.5%(4/17), P=0.045]. Wingspread score results at 6 and 12 months after operation showed excellent rate of postoperative anal function, which was not significantly different between two groups[ <3 months group : 81.3%(13/16) and 92.9%(13/14); >3 months group: 85.7%(12/14) and 92.3%(12/13), all P>0.05]. Postoperative barium enema results at 6 and 12 months after operation all showed normal shape of colon without residue of barium.</p><p><b>CONCLUSIONS</b>For newborns with rectosigmoid HD, single-stage definitive operation performed at the age less than 3 months has the advantages of shorter preoperative preparation time, less operating injury, shorter resected bowel, and faster postoperative recovery as compared to the age more than 3 months. If rectosigmoid HD is definitively diagnosed, early operation is suggested to perform at the age less than 3 months.</p>
