Objective To explore the clinical efficacy and safety of single-port laparoscopic ovarian cyst removal surgery.Methods A total of 145 patients who underwent laparoscopic surgery for ovarian cyst in Wenzhou People's Hospital from January 2023 to June 2024.Among them,single-port laparoscopic ovarian cystectomy+oophoroplasty was performed in 67 cases as single-port group,and traditional multi-port laparoscopic ovarian cystectomy+oophoroplasty was performed in 78 cases as multi-port group.Clinical indicators during and after surgery in two groups were recorded and compared.Results There were significant difference the operation time and pain scores at 1 day after surgery between two groups(P＜0.05).There was no significant difference in intraoperative bleeding,postoperative exhaust time and postoperative hospitalization time between two groups(P＞0.05).Neither of two groups had intraoperative vascular or nerve damage in the abdominal wall,and there were no postoperative complications such as incision infection,intestinal obstruction,or lower limb venous thrombosis,and the incision healed well.Continuing the follow-up for 3 months after discharge,both surgical procedures had no significant effect on menstruation,and there was no short-term recurrence of ovarian cyst in either case.Conclusion The single-port laparoscopic technique for the treatment of ovarian cyst incision is concealed and beautiful,the postoperative pain is lighter.No obvious effect on menstruation,and the curative effect is definite and safe.

Objective:To compare the therapeutic efficacy of the dual anteromedial and anterolateral approaches versus that of the anterior midline approach in the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse.Methods:A retrospective study was conducted to analyze the 21 patients who had been treated for Wahlquist type C medial tibial plateau fractures plus posterior column collapse at The Fourth Orthopedic Ward, The 72nd Group Army Hospital of PLA between January 2019 and August 2023. The cohort included 13 males and 8 females, with an age of (43.3±6.7) years. The left side was involved in 14 fractures and the right side in 7 ones. The patients were divided into 2 groups based on their surgical approaches: a dual-approach group ( n=13) undergoing fixation via the dual anteromedial and anterolateral approaches, and a single-approach group ( n=8) undergoing fixation via the anterior midline approach. Comparative parameters included operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, medial proximal tibial angle (MPTA), incision complications, postoperative bone mass reduction quality (evaluated according to the Rasmussen anatomical criteria for tibial condyle fracture reduction), lateral tibial plateau instability, incidence of genu varum, and post-traumatic arthritis. Functional recovery of the lower limb joints was assessed at the final follow-up using the Merchant criteria. Results:No statistically significant differences were observed in the baseline characteristics between the 2 groups preoperatively, indicating comparability ( P>0.05). All patients were followed up for a mean duration of (38.1±11.3) months. The postoperative MPTA in the dual-approach group (86.8°±0.8°) was significantly larger than that in the single-approach group (85.5°±0.9°) ( P<0.05). Genu varum occurred in 1 patient in the dual-approach group and in 4 patients in the single-approach group, while lateral tibial plateau instability was observed in 1 patient in the dual-approach group and in 4 patients in the single-approach group, showing statistically significant differences between the 2 groups ( P<0.05). No statistically significant differences were found between the 2 groups regarding operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, incidence of incision complications, or incidence of post-traumatic arthritis ( P>0.05). At the final follow-up, no statistically significant difference was observed in the functional recovery of the lower limb joints assessed by the Merchant criteria between the 2 groups ( P>0.05). Conclusion:In the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse, compared with the single anterior midline approach, the dual anteromedial and anterolateral approaches can restore more effectively the MPTA, and reduce the incidences of genu varum and lateral tibial plateau instability.

Objective:To investigate the value of tumor volume to uterine volume ratio (N/U) combined with the expression of alpha-fetoprotein (AFP), sugar antigen 199 (CA199) and human epididymal secretory protein 4 (HE4) in evaluating the pathologic grade and prognosis of endometrial carcinoma (EC) .Methods:A total of 160 EC patients admitted to Linyi Central Hospital from Jan. 2021 to Dec. 2023 were divided into low-grade group and high-grade group according to FIGO grading method, and were divided into poor prognosis group and good prognosis group according to cancer death, recrudescence. The levels of N/U, AFP, CA199 and HE4 in patients with different pathologic grades and prognosis were compared. COX regression was used to analyze the influencing factors of EC adverse prognosis, ROC curve was used to analyze the value of N/U combined with serum AFP, CA199 and HE4 in predicting EC adverse prognosis, and a nomogram model was constructed.Results:Pathological examination of 160 EC patients showed that 12 cases were non-endometrioid adenocarcinoma, 148 cases were endometrioid adenocarcinoma, 41 cases were high-grade and 119 cases were low-grade.According to the follow-up, 94 of the 160 EC patients had good prognosis and 66 had poor prognosis. The levels of N/U, AFP, CA199 and HE4 in the poor prognosis group were higher than those in the good prognosis group ( P<0.05). COX regression analysis showed that high levels of N/U, AFP, CA199 and HE4 were all factors affecting the poor prognosis of EC patients ( P<0.05). The AUC value of combined detection of N/U, AFP, CA199 and HE4 in predicting adverse prognosis of EC patients was higher than that of single detection ( Z=3.140, 3.658, 4.277, 4.378, P<0.05) .The ROC curve AUC (95% CI) of the training set and the validation set were 0.84 (0.77-0.92) and 0.90 (0.81-0.98) respectively for the training set and the validation set to predict the adverse prognosis of EC patients. Calibration curve results showed that the calibration curve for EC patients predicted by the nomogram model was close to the ideal curve ( P=0.521, 0.743). The DCA curve shows that the probability threshold of the nomogram model has a higher positive net return at 20%~100%. Conclusion:The levels of N/U, AFP, CA199 and HE4 in EC patients are related to the pathologic grade, and the combined detection of these indicators can predict the poor prognosis of EC patients, and the nomogram model constructed based on these indicators has high predictive value.

The cohort included 13 males and 8 females, with an age of (43.3±6.7) years. The left side was involved in 14 fractures and the right side in 7 ones. The patients were divided into 2 groups based on their surgical approaches: a dual-approach group ( n=13) undergoing fixation via the dual anteromedial and anterolateral approaches, and a single-approach group ( n=8) undergoing fixation via the anterior midline approach. Comparative parameters included operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, medial proximal tibial angle (MPTA), incision complications, postoperative bone mass reduction quality (evaluated according to the Rasmussen anatomical criteria for tibial condyle fracture reduction), lateral tibial plateau instability, incidence of genu varum, and post-traumatic arthritis. Functional recovery of the lower limb joints was assessed at the final follow-up using the Merchant criteria. Results:No statistically significant differences were observed in the baseline characteristics between the 2 groups preoperatively, indicating comparability ( P>0.05). All patients were followed up for a mean duration of (38.1±11.3) months. The postoperative MPTA in the dual-approach group (86.8°±0.8°) was significantly larger than that in the single-approach group (85.5°±0.9°) ( P<0.05). Genu varum occurred in 1 patient in the dual-approach group and in 4 patients in the single-approach group, while lateral tibial plateau instability was observed in 1 patient in the dual-approach group and in 4 patients in the single-approach group, showing statistically significant differences between the 2 groups ( P<0.05). No statistically significant differences were found between the 2 groups regarding operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, incidence of incision complications, or incidence of post-traumatic arthritis ( P>0.05). At the final follow-up, no statistically significant difference was observed in the functional recovery of the lower limb joints assessed by the Merchant criteria between the 2 groups ( P>0.05). Conclusion:In the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse, compared with the single anterior midline approach, the dual anteromedial and anterolateral approaches can restore more effectively the MPTA, and reduce the incidences of genu varum and lateral tibial plateau instability.
