ABSTRACT
Objective:To investigate the application value of transverse perineal arc incision approach in complete resection of presacral cyst in the lithotomy position.Methods:The retrospec-tive cohort study was conducted. The clinicopathological data of 114 patients who underwent com-plete resection of presacral cyst in Henan Cancer Hospital from August 2012 to October 2021 were collected. There were 14 males and 100 females, aged (35±9)years. All patients were diagnosed as presacral cysts by preoperative magnetic resonance imaging. Of the 114 patients, 76 patients undergoing intraoperative perineal arc incision approach in the lithotomy position were divided into the innovative group, and 38 patients undergoing intraoperative Kraske approach were divided into the traditional group. Observation indicators: (1) surgical situations and specimen; (2) postoperative situations; (3) Follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and com-parison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical situations and specimen. The operation time, volume of intraoperative blood loss, cases with intraoperative combined transabdominal approach or sacrectomy were (137±20)minutes, (261±101)mL, 0 in the innovation group, versus (136±34)minutes, (261±116)mL, 15 in the tradi-tional group, showing no significant difference in the operation time and volume of intraoperative blood loss between the two groups ( t=0.18, 0, P>0.05) and showing a significant difference in cases with intraoperative combined transabdominal approach or sacrectomy between the two groups ( P<0.05). Results of postoperative specimen anatomy in patients of the two groups showed complete removal of the cyst. (2) Postoperative situations. The time to postoperative removing presacral drainage tube, duration of postoperative hospital stay, cases with postoperative second stage healing of incision were (11.4±2.1)days, (13.5±3.5)days, 23 in the innovation group, versus (11.5±1.9)days, (13.7±3.8)days, 4 in the traditional group, showing no significant difference in the time to post-operative removing presacral drainage tube and duration of postoperative hospital stay between the two groups ( t=-0.20, -0.24, P>0.05) and showing a significant difference in cases with postoperative second stage healing of incision between the two groups ( χ2=5.46, P<0.05). Cases with postoperative severe complications were 4 and 2 in the innovation group and the traditional group, respectively, showing no significant difference between the two groups ( P>0.05). (3) Follow-up. All 114 patients were followed up for 48(range, 6?108)months. Cases with recurrence of cysts were 2 and 0 in the innovation group and the traditional group, respectively, showing no significant difference between the two groups ( P>0.05). During the follow-up period, the anal defecation control function of all patients was classified as grade A?B of Williams score. Conclusions:The transverse perineal arc incision approach in complete resection of presacral cyst in the lithotomy position is safe and feasible. Compared with Kraske approach, the transverse perineal arc incision approach in the lithotomy position is more suitable for patients with high presacral cyst.
ABSTRACT
Objective To discuss whether it is necessary to integrate metabolic indices into diagnosis of polycystic ovary syndrome (PCOS).Methods Taking ESHRE/ASRM diagnosis as the gold standard,51 women with PCOS and 47 women without PCOS were selected and divided into the intervention group and control group respectively from the Department of Gynecology in the Second Affiliated Hospital of Kunming Medical University between January 2013 and July 2014.Logistic regression based on principal component analysis and significant variables chosen through single factor analysis were used to establish the new diagnostic model which combined reproductive indices and metabolic indices.We evaluated the validity and reliability of the new diagnostic model by using ROC curve analysis.Finally,we analyzed the consistence and difference between the new diagnostic model and the gold standard.Results Thirteen significant variables were chosen using single factor analysis.ROC analysis showed that an area under the curve was 0.976 (P＜0.001) and the optimal cut-off point was 0.526 with a sensitivity of 96.08％,a specificity of 93.62％ and a consistency of93.88％.The new diagnostic model had superior validity and reliability.The two diagnostic methods had strong consistence (Kappa=0.877,P＜0.001) and no difference (x2=0.167,P=0.688).Conclusion Considering that the integration of metabolic indices does not change the diagnosis result,we come to a conclusion that it is unnecessary to integrate metabolic indices into diagnosis of PCOS.
