PURPOSE: The purpose of this cadaveric study was to compare the volume and weight of bone graft harvested using the curettage vs. the trephination technique from the anterior iliac crest. METHODS: Embalmed cadavers were studied in this experimental research. The right hemipelvis of each cadaver was used for the trephine bone harvesting technique, whereas the left hemipelvis was used for the conventional curettage technique. The weight and the volume of the harvested bone were measured and statistically compared between the 2 sides. The Wilcoxon Signed-Rank test was employed to compare the graft volume and weight obtained from the right and left sides of the hemipelvis. RESULTS: Ten embalmed adult cadavers were used in this study. All subjects were Caucasian males with a mean age of 59.8 years (range 44 - 73 years) at the time of death. A total of 81 cylindrical bone grafts were harvested from the right iliac crest. In 9 out of 81 (11.1%), the cortex of the ilium was penetrated by the chisel. The mean weight of the bone graft harvested with the trephine technique (26.97 ± 2.32) g was heavier than that harvested with the curettage technique (23.74 ± 2.09) g (p = 0.007). Similarly, the volume of the bone graft was higher in the trephine technique (8.40 ± 0.84) cm³ compared to the curettage technique (6.60 ± 1.26) cm³ (p = 0.011). The trephination technique lasted a mean of (12.76 ± 1.87) min (range 10.30-16.10 min), while the curettage technique lasted a mean of (14.53 ± 0.89) min (range 13.50-16.00 min) (p = 0.028). CONCLUSION: Harvesting anterior iliac crest bone graft with the trephine technique provides a higher bone volume and weight than the conventional curettage technique. The trephine technique might be advocated over the curettage technique, especially when a large amount of autologous bone graft is required. However, a meticulous harvesting technique should be followed to prevent complications. In particular, the three-dimensional anatomy should be kept in mind, and the depth of trephination should be well-controlled.

Atypical placental site nodules (APSN) are a rare form of trophoblastic disease in pregnancy. There is limited research on APSN, and treatment methods are controversial, with unclear prognosis. This study collected clinical and prognostic data of 5 patients diagnosed with APSN at Xiangya Hospital of Central South University from June 2008 to June 2023, aiming to provide a better understanding of the prognosis of APSN patients and offer scientific evidence for clinical treatment. The average age of the 5 APSN patients was 32.60 years, and all patients underwent dilation and curettage or hysteroscopic surgery or hysteroscopic surgery without hysterectomy. Except for one patient who was lost to follow-up after 30 days, the remaining 4 patients were followed up for 1.36 to 4.61 years. During the follow-up, gynecological ultrasound did not show abnormalities, and serum human chorionic gonadotropin (HCG) tests were negative, with no evidence of malignancy. A search of both English and Chinese databases yielded 8 articles reporting the diagnosis, treatment, and follow-up outcomes of APSN, with 37 cases cumulatively followed up. Among them, 2 (5.41%) cases developed epithelial trophoblastic tumors or placental site trophoblastic tumors during follow-up, but there is insufficient evidence to determine whether these tumors directly originated from APSN or were secondary to APSN. Currently, there is no direct evidence suggesting that APSN has the potential for malignant transformation. Patients with APSN who have completed their childbearing may consider preserving their uterus, but close follow-up is needed to further evaluate the prognosis.

OBJECTIVES: This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment. METHODS: Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed. Then, the data were imported into MIMICS software to observe 3D changes in the position and structure of the mandibular nerve canal, followed by a comparative analysis. RESULTS: The total displacement of the mandibular canal was (1.89±0.21) mm on the decompression side and (0.80±0.19) mm on the curettage side. Vertically, the displacement range of the mandibular canal on the decompression side (M=1.03, SD=0.17) was larger than on the curettage side (M=0.52, SD=0.010) within nine months post-operation. In the buccal-lingual direction, the ratio of the thickness of the buccal plate to the lingual plate gradually increased with time. The amount of bone reconstruction at the part of the mandibular nerve canal closest to the cyst was (1.75±0.15) mm on the decompression side and (1.45±0.09) mm on the curettage side after nine months. CONCLUSIONS The mandibular nerve canal showed varying degrees of recovery and "relocation" after two surgical procedures. Osteogenesis around the mandibular nerve canal was more remarkable after decompression than after curettage. Therefore, for large odontogenic keratocyst, decompression is recommended as the initial treatment, followed by secondary curettage nine months later.

INTRODUCTION

Hysteroscopy is the gold standard procedure for the evaluation and diagnosis of intrauterine pathologies. The optimal time to do hysteroscopy is during the proliferative phase. However, for women with irregular bleeding, the optimal time is unpredictable. Besides pharmacological means, mechanical endometrial preparation could be done.

The objective of this study was to determine the effect of suction curettage on visualization, operative time, fluid deficit, and histopathologic diagnosis among perimenopausal women with abnormal uterine bleeding (AUB) and unprepared endometrium prior to operative hysteroscopy.

Thirty-four (34) perimenopausal women admitted for AUB with unprepared endometrium for operative hysteroscopy who consented to participate were recruited and randomly divided into two groups: 18 women had suction curettage done prior to operative hysteroscopy and 16 women had operative hysteroscopy done alone. The following data were obtained for each group: (1) improvement in clarity (i.e., visualization of fundus and both tubal ostia), (2) operative time from entry to withdrawal of the resectoscope (measured in minutes), (3) fluid deficit, and (4) final histopathological diagnosis. P 

Women who underwent suction curettage prior to operative hysteroscopy had improved visualization (72.2%, P < 0.001), shorter operative time (29.06 ± 7.06 min vs. 35.5 ± 7.2 min, P = 0.013), no difference in fluid deficit (P = 0.276), and the histopathologic diagnosis (P = 0.470).

Suction curettage prior to operative hysteroscopy among perimenopausal women with AUB and unprepared endometrium improved visualization and shortened operative time without affecting fluid deficit and histopathologic diagnosis.

BACKGROUND

Molluscum contagiosum is a benign viral infection affecting children, sexually active adults, and immunocompromised individuals. Modified autoinoculation (MAI) is a procedure in which a solitary lesion of molluscum contagiosum lesion is inoculated in the affected skin to stimulate an immune response, thereby clearing the infection.

This study aimed to compare the efficacy and safety of modified autoinoculation versus curettage in the treatment of molluscum contagiosum infection.

This study was an assessor-blinded, randomized therapeutic trial performed at the Department of Dermatology of Jose R. Reyes Memorial Medical Center. 52 patients with newly diagnosed molluscum contagiosum that had not been previously treated were assigned randomly using computer-generated randomization to either curettage or MAI. 26 patients were allocated in each treatment group. Patients were followed-up every 2 weeks for 3 months and at 6 months to evaluate clearance and recurrence rates along with adverse events.

Curettage was significantly a more effective treatment than MAI in achieving higher clearance rates and reducing recurrences. Adverse events did not differ significantly.

While MAI was a less invasive alternative, curettage remains superior in terms of efficacy and recurrence prevention. However, MAI may still be considered for patients seeking a less painful procedure, especially in children and those with extensive lesions.

OBJECTIVE: To observe the clinical therapeutic effect of the combination of electroacupuncture (EA) at METHODS: A total of 58 patients after uterine curettage of incomplete abortion were randomized into an EA group and a western medication group, 29 cases in each one. In the western medication group, mifepristone tablets were administered orally, 2 tablets each time, once daily. In the EA group, on the base of the treatment as the western medication group, EA was applied to RESULTS: After treatment, the intrauterine residue area and CDFI blood flow signal positive rate were all reduced as compared with the values before treatment in patients of the two groups ( CONCLUSION The combined treatment of electroacupuncture at

Decompression and curettage can result are effective as treatments for large jaw cysts, which are common diseases in the clinic. Based on a treatment used in a previous study, this paper proposes a "three-step method" to treat large jaw cyst and repair the bone defect by decompression, curettage, and autologous dental bone powder implantation. This paper introduces the processes and key points of the operation involved in the abovementioned method.

OBJECTIVE: To evaluate the efficacy of combined oral medroxyprogesterone acetate (MPA)/levonorgestrel-intrauterine system (LNG-IUS) treatment and to compare the diagnostic accuracy of endometrial aspiration biopsy with dilatation & curettage (D&C) in young women with early-stage endometrial cancer (EC) who wished to preserve their fertility. METHODS: A prospective phase II multicenter study was conducted from January 2012 to January 2017. Patients with grade 1 endometrioid adenocarcinoma confined to the endometrium were treated with combined oral MPA (500 mg/day)/LNG-IUS. At 3 and 6 months of treatment, the histologic change of the endometrial tissue was assessed. The regression rate at 6 months treatment and the consistency of the histologic results between the aspiration biopsy and the D&C were evaluated. RESULTS: Forty-four patients were enrolled. Nine voluntarily withdrew and 35 patients completed the protocol treatment. The complete regression (CR) rate at 6 months was 37.1% (13/35). Partial response was shown in 25.7% of cases (9/35). There were no cases of progressive disease and no treatment-related complications. A comparison of the pathologic results from aspiration biopsy and D&C was carried out for 33 cases. Fifteen cases were diagnosed as “EC” by D&C. Among these, only 8 were diagnosed with EC from aspiration biopsy, yielding a diagnostic concordance of 53.3% (ĸ=0.55). CONCLUSION: Combined oral MPA/LNG-IUS treatment for EC showed 37.1% of CR rate at 6 months. Considering the short treatment periods, CR rate may be much higher if the treatment continued to 9 or 12 months. So, this treatment is still a viable treatment option for young women of early-stage EC. Endometrial aspiration biopsy with the LNG-IUS in place is less accurate than D&C for follow-up evaluation of patients undergoing this treatment.

Uterine arteriovenous vascular malformation (UAVM) is a disease that causes excessive bleeding. The symptoms do not subside without proper treatment and this can lead to life-threatening situations. The correct diagnosis of UAVM can be complicated if the patient's uterus did not completely discharge everything during abortion (in broader terms, retaining remnants of the products of conception). In this case, Doppler ultrasonography and computed tomography angiography with 3-dimensional rendering were used to analyze the cause of bleeding and provide proper treatment of this patient. Then, uterine artery embolization, dilatation, and curettage were performed safely and successfully. The patient no longer had symptoms of vaginal spotting during the planned follow up care. UAVM is uncommon; however, if reproductive-age women show repeated abnormal vaginal bleeding after dilatation and curettage, a diagnosis of UAVM must be considered based on the medical history and examination.

OBJECTIVE: The aims of this study were to introduce surgical guidelines, and to evaluate the feasibility and safety of a robotic single-site staging (RSSS) operation for early-stage endometrial cancer. METHODS: Patients with a preoperative diagnosis of endometrial cancer (International Federation of Gynecology and Obstetrics stages IA to IB) from endometrial curettage and preoperative imaging studies were selected at Dongsan Medical Center from March 2014 to November 2015. All surgical procedures, including hysterectomy, salpingo-oophorectomy, bilateral pelvic node dissection, and cytology aspiration, were performed by robotic single-site instruments (da Vinci Si® surgical system; Intuitive Surgical, Sunnyvale, CA, USA). RESULTS: A total of 15 women with early-stage endometrial cancer underwent the RSSS operation. The median patient age and body mass index were 53 years (range, 37–70 years) and 25.4 kg/m2 (range, 18.3–46.4 kg/m2). The median docking time, console time, and total operative time were 8 minutes (range, 4–15 minutes), 75 minutes (range, 55–115 minutes), and 155 minutes (range, 125–190 minutes), respectively. The median retrieval of both pelvic lymph nodes was 9 (range, 6–15). There were no conversions to laparoscopy or laparotomy. CONCLUSION: The RSSS operation is feasible and safe in patients with early-stage endometrial cancer. In this study, operative times were reasonable, and the surgical procedure was well-tolerated by the patients. Further evaluation of patients with early-stage endometrial cancer should be performed in large-scale comparative studies using the laparoendoscopic, single-site staging operation to confirm the safety and benefits of the RSSS operation for early-stage endometrial cancer.
