Research progress on the treatment of gingival pigmentation / 口腔疾病防治

@#Gingival pigmentation is a nonplaque gum disease. Patients are often afraid to communicate with others because of gum color problems, which affect the social and mental health of patients. The commonly used treatment methods for gingival pigmentation include scalpel excision, gingival grinding, laser therapy, cryosurgery and electrosurgery. In this paper, the progress of gingival pigmentation treatment was reviewed in terms of bleeding, pain, tissue healing and recoloring. The results showed that the clinical effect of laser treatment was better. Among them, the semiconductor laser had more advantages in reducing bleeding, pain and the restaining rate, while the Er:Cr:YSSG/Er:YAG laser performed better for promoting tissue healing. Clinicians can choose the best kind of laser to use according to the actual situation. For patients with thin gingival biotypes, floating gingival transplantation or substitute materials can be selected to restore the gingival morphology. With the in-depth study of melanin regulation mechanisms, various drugs, such as ascorbic acid, natural peptides, synthetic peptides and derivatives, may be the main research direction for the treatment of gingival pigmentation in the future.

Clinical study of hysteroscopical electroresection of FIGO type 3 myoma / 中华妇产科杂志

Objective:To analyze the clinical application and to evaluate the efficiency of hysteroscopical electroresection of International Federation of Gynecology and Obstetrics (FIGO) type 3 myoma.Methods:The clinical data of patients who underwent hysteroscopical electroresection single FIGO type 3 myoma in Obstetrics and Gynecology Hospital of Fudan University from January 2019 to October 2021 were collected retrospectively. The clinical symptoms, myoma size, location, operation time, intraoperative bleeding, surgical complications and postoperative follow-up were recorded, and the subsequent pregnancy outcomes were followed-up.Results:Totally 35 patients with FIGO type 3 myoma were included in this study. The average age was (36.6±4.7) years old, the diameter of myoma was (4.0±1.2) cm (range: 2.0-5.8 cm). The rate of complete resection of myoma in one operation was 86% (30/35), the average operation time was (41±15) minutes (range: 20-65 minutes), and the average intraoperative bleeding was (24±18) ml (range: 5-150 ml). No complications such as uterine perforation, massive hemorrhage, hyperhyderation syndrome and infection occurred in all patients perioperation. There were 20 cases with significant increase of menstruation before operation, the cure rate and effective rate of hysteroscopical electroresection of FIGO type 3 myoma were 75% (15/20) and 95% (19/20). There were 24 patients with fertility requirements, their average follow-up time was (14.5±6.8) months, the pregnancy rate within 1 year after operation was 79% (19/24), and the average postoperative pregnancy time was (5.8±3.4) months. There were 15 cases who had completed delivery after operation, including 10 cases of vaginal delivery and 5 cases of cesarean section, and none of them had uterine rupture.Conclusions:Hysteroscopy could effectively resect FIGO type 3 myoma. Hysteroscopical electroresection of FIGO type 3 myoma is minimally invasive with rapid postoperative recovery and could achieve pregnancy in a short time, which is not only helpful to reduce the amount of menstruation, but also beneficial for the prognosis of fertility. It should be carried out by the experienced hysteroscopists.

Stratified research on related risk factors of CINⅡ + in CINⅠ patients diagnosed by endocervical curettage under colposcopy / 中华妇产科杂志

Objective:To estimate risks of cervical intraepithelial neoplasia (CIN) Ⅱ or worse (CINⅡ +) on loop electrosurgical excisional procedure (LEEP) specimens with the diagnosis of endocervical curettage (ECC) CINⅠ compared with biopsy CINⅠ, and also to investigate the hierarchical management scheme of ECC CINⅠ based on the relevant factors of CINⅡ + risk. Methods:(1) A retrospective computer-based research for subjects enrolled in the Obstetrics and Gynecology Hospital, Fudan University from Jan. 2013 to Jun. 2021 was performed. The case group comprised women with an ECC CINⅠ (ECC results of CINⅠ with colposcopy-directed biopsy results ≤CINⅠ), and the control group comprised women with a biopsy CINⅠ (colposcopy-directed biopsy results of CINⅠ with negative ECC findings) were divided after LEEP surgery and diagnosis in the next three months. The clinical data of all patients before LEEP were analyzed, and the pathological diagnosis between two groups after LEEP was compared. (2) Variables, including age, cytology, high-risk human papillomavirus (HR-HPV), ECC results, cervical transformation zone (TZ) and colposcopy impression, were included to describe the characteristics and compare the incidence of LEEP CINⅡ +. (3) Univariate analysis and Multivariate logistic regression method were used to analyze the related factors that affect the LEEP CINⅡ + in CINⅠ patients. Further, the specific risks caused by related factors and conduct a stratified study in LEEP CINⅡ + were analyzed. Results:(1) Overall, 2 581 women with ECC CINⅠ or biopsy CINⅠ diagnosis who underwent LEEP participated in the study with the mean age (43.6±9.5) years old. Chi square test found that the age and cytology of patients in ECC CINⅠ group were statistically different from those of biopsy CINⅠ group (all P<0.05). There was no significant difference in HR-HPV detection, TZ type and colposcopy impression between the two groups (all P>0.05). ECC CINⅠ comprised 957 women, with LEEP histopathology results revealing 288 (30.1%, 288/957) CINⅡ +, which was significantly higher than that of biopsy CINⅠ which was comprised 1 624 women, with LEEP histopathology results showing 333 (20.5%, 333/1 624) CINⅡ + ( χ2=30.31, P<0.001). (2) Compared by LEEP CINⅡ + with LEEP ≤CINⅠ group, there were no significant difference in the age, HR-HPV, colposcopy impression (all P>0.05); but there were significantly differences in cytology, ECC CINⅠ, type Ⅲ TZ (all P<0.001). Multivariate logistic regression analysis showed that atypical squamous epithelial cells (ASC-H; OR=2.77, 95% CI: 2.04-3.77), high-grade squamous intraepithelial lesions and worse (HSIL +; OR=2.93, 95% CI: 2.24-3.81), ECC CINⅠ ( OR=1.89, 95% CI: 1.56-2.29) and type Ⅲ of TZ ( OR=1.76, 95% CI: 1.45-2.11) were independent risk factors for LEEP CINⅡ + (all P<0.05). (3) When cytology was ≤low-grade squamous intraepithelial lesion (LSIL) and ≥ASC-H, the detection rate of CINⅡ + in ECC CINⅠ was significantly higher than that of biopsy CINⅠ (all P<0.001). In ECC CINⅠ, the rate of CINⅡ + with cytology ≤LSIL was significantly lower than that in cytology ≥ASC-H (56.0% vs 25.9%; χ2=49.38, P<0.001). In type Ⅰ/Ⅱ of TZ, the detection rate of CINⅡ + between ECC CINⅠand biopsy CINⅠ had no significantly different; while in type Ⅲ of TZ, there was significantly different (72.7% vs 46.2%; χ2=4.02, P=0.045). In ECC CINⅠ, type Ⅲof TZ was significantly higher in the rate of CINⅡ + than that of type Ⅰ/Ⅱ of TZ (72.7% vs 21.7%; χ2=16.38, P<0.001). When cytology ≥ASC-H, type Ⅲ of TZ and colposcopy impression of HSIL were combined, the rate of CINⅡ + in ECC CINⅠ was 6/6 while 1/3 in biopsy CINⅠ. Conclusions:Cytology ≥ASC-H, ECC CINⅠ and type Ⅲ TZ are the risk factors of LEEP CINⅡ +. However, cytology ≥ASC-H is more valuable in predicting LEEP CINⅡ + than ECC CINⅠ. For patients with ECC CINⅠ to perform LEEP, it is recommended that cytology ≥ASC-H is taken as the first level stratification, and type Ⅲ TZ is taken as the second level stratification. The colposcopy impression of patients is recommended for a reference parameter.

Research progress of surgical smoke / 国际外科学杂志

Surgical smoke is a by-product of aerosol produced by electrosurgical equipment, laser and other energy equipments when cuting tissue or coagulating blood vessels. It contains non-active particles, organic chemicals, pathogens, viable cells and so on. The characteristics of surgical smoke components produced by different types of tissues or using different kinds of energy devices are different. For example, the average diameter of smoke particles produced by electrocautery is smaller, the possibility of viable cells and pathogens in surgical smoke produced by ultrasonic knife is higher. According to the characteristics of its composition, surgical smoke may be an imporant risk factor to the health and safety of operating room staff and patients. The use of surgical masks, suction devices and portable smoke evacuation systems can reduce the risk to some extent. But the most operating room staff don′t take corresponding measures to protect them. In this paper, the characteristics of surgical smoke and the research progress of protective measures will be briefly reviewed.

A Retrospective Study of Coronary Artery Bypass Grafting with Low-Thermal Plasma Dissection Device Compared to Conventional Monopolar Electrosurgery

Abstract Introduction: The objective of this study is to compare the effects of conventional monopolar electrosurgery (CMES) and low-thermal plasma kinetic cautery (PKC) on complications such as bleeding, abnormal wound healing, pain, and drainage in patients who underwent on-pump coronary artery bypass grafting (CABG). Methods: This retrospective clinical study included 258 patients undergoing CABG; the patients were randomized to PKC (PEAK PlasmaBlade, n=153) and CMES (n=105) groups. The patients' clinical data were examined retrospectively for biochemical variables, postoperative drainage, post-surgery erythrocyte suspension transfusion count, surgical site pain examined with visual analogue scale (VAS), and wound healing. Two-sided P-value > 0.05 was considered as statistically significant. Results: The median post-surgery erythrocyte suspension transfusion number was significantly lower with PKC compared to CMES (0 [0-1] vs. 1 [1-4], respectively, P<0.001). Mean postoperative drain output and time until removal of drain tubes were significantly lower with PKC compared to CMES (300±113 vs. 547±192 and 1.95±1.5 vs. 2.44±1.8; P<0.001 and P=0.025, respectively). Mean VAS score for spontaneous and cough-induced pain were significantly lower with PKC compared to CMES (1.98±1.51 vs. 3.94± 2.09 and 3.76±1.46 vs. 5.6±1.92; P<0.001 for both comparisons). Reoperation due to bleeding was significantly higher with CMES compared to PKC (0 vs. 11 [7.2%], P=0.001). Conclusion: Use of PKC during CABG considerably reduces postoperative drainage, need for blood transfusion, reoperation due to bleeding, and postoperative pain. PCK appears to be a good alternative to CMES for CABG.

Risk stratified management of cervical adenocarcinoma in situ based on cone margin state / 中华妇产科杂志

Objective:To investigate the hierarchical management scheme of cervical adenocarcinoma in situ (AIS) based on cervical conization margin state.Methods:All medical records of 249 patients diagnosed as AIS by loop electrosurgical excision procedure (LEEP) conization from Jan. 2010 to Dec. 2015 in Obstetrics and Gynecology Hospital of Fudan University were retrospectively reviewed, to explore the relationship between the status of the resection margin and the residual lesion after LEEP, and the multivariate logistic regression method was used to analyze the related factors that affect the residual lesion after LEEP in cervical AIS patients.Results:(1) The age of 249 cervical AIS patients was (40±8) years old (range: 23-71 years old). Of the 249 patients, 19 (7.6%, 19/249) had residual lesions; 69 cases were pathologically diagnosed as AIS after LEEP, and the residual lesion rate was 13.0% (9/69), which was significantly higher than that of AIS + high-grade squamous intraepithelial lesion [5.6% (10/180); χ2=3.968, P=0.046]; 33 cases were multifocal lesions, the residual rate of lesions was 21.2% (7/33), which was significantly higher than that of single focal lesions patients [5.6% (12/216); χ2=7.858, P=0.005]; 181 patients underwent endocervical curettage (ECC) before surgery, the residual rate of lesions in ECC-positive patients was 14.0% (14/100) , significantly higher than that of ECC-negative patients [4.9% (4/81); χ2=4.103, P=0.043]. (2) Among 249 cases of AIS patients, the positive rate of resection margins after LEEP was 35.3% (88/249); the residual rate of lesions in patients with positive resection margins (14.8%, 13/88) was significantly higher than those with negative margins [3.8%(6/156); χ2=9.355, P=0.002]. The age of patients underwent total hysterectomy after LEEP was (43±7) years old, which was significantly higher than that of patients who did not undergo total hysterectomy [(37±8) years old; t=6.518, P<0.01].Among the patients underwent total hysterectomy after LEEP, 3 cases (2.0%, 3/152) had fertility requirements, while 38 cases (39.2%, 38/97) did not underwent total hysterectomy, the difference between the two groups was statistically significant ( χ2=59.579, P<0.01). Among the 152 patients who underwent total hysterectomy after LEEP, the residual rate of lesions was 11.8% (18/152); the residual rate of lesions in patients with positive resection margins was significantly higher than that of patients with negative resection margins [18.8% (12/64) vs 7.0% (6/86); χ2=4.861, P=0.028]. The median follow-up time of 97 patients who did not undergo total hysterectomy after LEEP was 32 months (range: 4-70 months). During the follow-up period, 3 cases of cervical AIS recurrence (3.1%, 3/97) and were followed by hysterectomy,no invasive adenocarcinoma were seen. (3) Multivariate logistic regression analysis showed that the positive resection margin ( OR=4.098, 95% CI: 1.235-13.595, P=0.021), multifocal lesions ( OR=5.464, 95% CI: 1.494-19.981, P=0.010) were independent risk factors that affected the residual lesions in patients with cervical AIS after LEEP. Conclusions:The cervical AIS patients after LEEP conization suggested be stratified by cone margin state as the first-line stratified index, age and fertility needs as the second-line stratified management index. The individualized management plan should be developed based on comprehensive assessment of high-risk factors of residual lesions.

Is electrosurgery fulguration a better procedure for Bartholins gland cyst?

SUMMARY OBJECTIVE To evaluate the effectiveness of electrosurgery fulguration as a treatment for Bartholin's gland cysts. DESIGN Retrospective study with a comparative control group performed on Hospital Brigadeiro and in the Disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo from February 2005 to March 2009. Patients: Patients with Bartholin's gland cyst were divided into three treatment groups: group 1 electrosurgery (n=169 cases); group 2 - gland excision with the conventional technique using a cold scalpel (n = 51 cases); group 3 - marsupialization (n=11 cases). We reviewed the clinical and surgical history, physical examination, description of the surgical technique, postoperative results (success and complications), and follow-up data. RESULTS There is no difference between groups in relation to intraoperative bleeding, hematoma, and complete healing in a single treatment session. However, electrosurgery shows the lower percentage of recurrences 18 (10,7%) compared to the Marsupialization technique (group 3, p=.031). Recurrences occurred in 18 (10,7%), 3 (5,9%), and 4 (36,4%) cases. After retreatment by the same technique, there was a complete cure rate of 90% (152/169) for group 1, and 98% (50/51) for group 2. The cost of group 1 was lower than that of other groups. CONCLUSION The fulguration with electrosurgery of the capsule of Bartholin's cyst is an effective method of treatment, andthe cost of this technique is lower than the conventional technique and marsupialization.

RESUMO OBJETIVO Avaliar a eficácia da fulguração da eletrocirurgia como tratamento para os cistos da glândula de Bartholin. MÉTODOS Estudo retrospectivo, grupo controle comparativo realizado no Hospital Brigadeiro e disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, de fevereiro de 2005 a março de 2009. Pacientes com cisto de glândula de Bartholin foram divididos em três grupos de tratamento: grupo 1 - eletrocirurgia (n = 169 casos); grupo 2 - excisão da glândula com técnica convencional utilizando bisturi frio (n = 51 casos); grupo 3 - marsupialização (n = 11 casos). Revisamos a história clínica e cirúrgica, o exame físico, a descrição da técnica cirúrgica, os resultados pós-operatórios (sucesso e complicações) e os dados de acompanhamento. RESULTADOS Não há diferença entre os grupos em relação ao sangramento intraoperatório, hematoma e cicatrização completa em uma única sessão de tratamento. No entanto, a eletrocirurgia mostrou o percentual mínimo de recidivas, 18 (10,7%), em relação à técnica de marsupialização (grupo 3, p = 0,031). Recorrências ocorreram em 18 (10,7%), três (5,9%) e quatro (36,4%) casos. Após o retratamento pela mesma técnica, houve taxa de cura completa: 90% (152/169) para o grupo 1 e 98% (50/51) para o grupo 2. O custo do grupo 1 foi menor do que os dos outros grupos. CONCLUSÃO A fulguração com eletrocirurgia da cápsula do cisto de Bartholin é um método efetivo de tratamento, mas o custo dessa técnica é menor do que a técnica de convenção e a marsupialização.

Efficacy and safety of cryotherapy, cold cone or thermocoagulation compared to LEEP as a therapy for cervical intraepithelial neoplasia: Systematic review / Eficacia y seguridad de crioterapia, cono frio o termo-coagulación en comparación con LEEP como terapia para la neoplasia intraepitelial cervical: Revisión sistemática

ABSTRACT OBJECTIVES To determine the efficacy and safety of the use of cryotherapy, cold knife or thermocoagulation compared to Loop Electrosurgical Excision Procedure (LEEP) for the treatment of cervical intraepithelial neoplasia. METHODS Systematic review with meta-analysis of randomized controlled trials in women with cervical intraepithelial neoplasia undergoing treatment with cryotherapy, cold knife, or thermo-coagulation compared with LEEP, to estimate its efficacy and safety. The search was conducted on MEDLINE/PUBMED, Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus, until September 2018. RESULTS The total of 72 studies were identified, of which only 8 studies met the inclusion criteria. The treatment of CIN with cold knife decreases the risk of residual disease compared with LEEP (RR, 0.54, 95%CI, 0.30-0.96, p = 0.04). The management of premalignant lesions with cryotherapy, compared with LEEP, increases the risk of disease recurrence by 86% (RR, 1.86, 95%CI, 1.16-2.97, p = 0.01), increases the risk of infections (RR, 1.17, 95%CI, 1.08-1.28, p < 0.001) and reduces the risk of minor bleeding by 51% (RR, 0.49, 95%CI) %, 0.40-0.59, p ≤ 0.001). CONCLUSIONS The treatment of premalignant lesions of cervical cancer with cold knife reduces the risk of residual disease. Nevertheless, cryotherapy reduces the risk of minor bleeding in the 24 hours after treatment and increases the risk of recurrence of disease and infections.

Abstract Objective To analyze the signs and symptoms presented by doctors in surgery and anesthesiology residency programs exposed to surgical smoke. Method Prospective cohort study with resident doctors exposed to surgical smoke in a teaching hospital. There was 17-month follow-up of residents from the years 2015 and 2016, who met the criteria of being regularly enrolled in a surgery or anesthesiology residency and not being a smoker. The data collection instrument was composed of sociodemographic, academic data and the signs and symptoms related to the inhalation of surgical smoke, cited in the literature. The data analysis was descriptive and inferential, by statistical tests and measures of effect. Results The sample consisted of 39 residents, of which most were male (56.4%) and below 30 years old (74.3%). There was a prevalence of gynecology and obstetrics residents (30.8%), followed by general surgery (28.2%) and anesthesiology (20.5%). Burning in the pharynx (p=0.030), nausea and vomiting (p=0.018) and eye irritation (p=0.050) occurred in the first year of residence. The risk of developing burning in the pharynx was 7.765 times greater (p=0.019) in females when compared to males. Conclusion The signs and symptoms analyzed occurred within 12 months of the beginning of the course and the risk of burning in the pharynx was higher in females, which indicates exposure to the risks of inhalation of surgical smoke and, therefore, points to the need for the adoption of individual and collective protection measures.

Successful treatment of conjunctival lymphangiectasia accompanied by corneal dellen using a high-frequency radiowave electrosurgical device

A 62-year-old man presented with a 1-month history of right eye pain unresponsive to artificial tears and topical steroids. At presentation, bullous yellowish fluid collection was noted in the nasal conjunctiva. Corneal thinning and opacity were observed at the 3 o'clock position of the cornea. High-frequency radiowave ablation and biopsy were performed at the affected area. Conjunctival lymphangiectasia was confirmed by excisional biopsy. An improvement in the degree of corneal dellen and chemosis was evident 1 week after ablation. Use of a high-frequency radiowave electrosurgical device may be a simple and effective treatment option for symptomatic conjunctival lymphangiectasia.

Evaluation of Subconjunctival Remnant Particles after High-frequency Radio-wave Electrosurgery for Conjunctivochalasis

PURPOSE: To investigate the clinical manifestations and properties of remnant particles in the subconjunctival space after high-frequency radio-wave electrosurgery for conjunctivochalasis. METHODS: We performed a retrospective, observational case series with in vitro experimental imaging in nine eyes from eight patients who presented with small dark-gray lesions during follow-up after high-frequency radio-wave electrosurgery for conjunctivochalasis. General examination including slit-lamp examination and visual acuity testing was performed preoperatively and postoperatively. During follow-up, we evaluated remnant particles and any other complications including granuloma or conjunctival injection with slit-lamp photography and anterior optical coherence tomography. Coagulation tips were investigated with scanning electron microscope and energy dispersive X-ray spectroscopy to analyze the insulating electrode and assess changes to tips after repeated use. RESULTS: None of the patients included in this study experienced any change in visual acuity or major complications postoperatively. Small dark-gray lesions (0.3 to 0.5 mm in size) were observed in the inferior bulbar sub-conjunctival space in the location where high-frequency radio-wave electrosurgery had been performed. Cirrus high-definition optical coherence tomography images revealed focal hyper-reflection with a posterior shadow, suggesting foreign particles. Scanning electron microscopy and energy dispersive X-ray spectroscopy imaging analysis revealed peaks of carbon and fluorine complexes, consistent with the polytetrafluoroethylene coating on the electrode. CONCLUSIONS: There were no instances of inflammatory reaction, particle migration, or major complications due to particles. Physicians should be aware of the possibility of remnant polytetrafluoroethylene particles in subconjunctival tissue when using insulated coagulation tips subjected to repeat sterilization.

Analysis of recurrence and its influencing factors in patients with cervical HSIL within 24 months after LEEP / 中华妇产科杂志

Objective To analyze clinical outcome of high grade squamous intraepithelial lesion (HSIL) within 24 months after loop electrosurgical excision procedure (LEEP),and to explore risk factors of recurrent cervical HSIL,the risk of progress into cervical cancer and methods of follow-up.Methods This retrospective study was carried out on 1 005 patients who underwent LEEP,diagnosing with HSIL after LEEP from January 2011 to December 2013 at Obstetrics and Gynecology Hospital Affiliated to Fudan University to confer the difference between non-recurrent group and recurrent group 24 months after the LEEP conization.Patients were followed with ThinPrep cytologic test (TCT),high risk HPV (HR-HPV) test,colposcopy guided biopsy.Results A total of 1 005 cases were enrolled in this study with HSIL in the LEEP specimen,no residual HSIL in the 6-month follow up,and have follow up records in 24 months after LEEP.HSIL recurred in 5 cases,microinvasive carcinoma in 1 case,low grade squamous intraepithelial lesion (LSIL) in 17 cases at 12 months follow-up.HSIL recurred in 8 cases,LSIL in 11 cases,adenocarcinoma in situ in 1 case,and invasive cervical carcinoma in 1 case in Ⅰ b1 stage at 24 months after LEEP.The recurrence rate was 1.3％ (13/1 005),and the progression rate was 0.3％ (3/1 005).There was no significant difference in age,length,circumference and width of LEEP between recurrent and non-recurrent patients (P ＞ 0.05).The recurrence rate was highest in the endocervical positive margin group with 3/16,which was higher than ectocervical positive margin and negative margin (P＜0.01,P=0.040,respectively).The recurrence rate of endocervical positive margin group and fibrous interstitial positive margin group showed no significant difference (P=0.320).There was no significant difference between ectocervical positive margin and negative margin [2.8％ (2/72) vs 0.7％ (6/882),P=0.117].Postoperative cytological examination combined with HR-HPV detection has a high sensitive and high negative predictor value of HSIL recurrence with both 100.0％.Multivariate logistic regression analysis showed that positive endocervical positive margin,abnormal follow-up cytological examination and positive HR-HPV after LEEP were independent factors affecting recurrence of HSIL patients after LEEP (P＜0.05).Conclusions Age,length,circumference and width of LEEP have no effect on recurrence within 24 months after HSIL.The high risk factors for HSIL recurrence within 24 months after LEEP in HSIL patients include:positive HPV,abnormal cytology,and positive endocervical positive margin.Colposcopy biopsy and endocervical curettage have important role in diagnosing HSIL recurrence and progression.

Analysis of risk factors for residual lesion of HSIL after loop electrosurgical excision procedure / 中国实用妇科与产科杂志

OBJECTIVE: To analyze clinical outcome of high-grade squamous intraepithelial lesion(HSIL)half a year after loop electrosurgical excision procedure(LEEP).METHODS: The retrospective study was carried out on 752 patients who underwent LEEP,with HSIL in the LEEP histopathology from January 2018 to December 2018 at Shanghai First Maternity and Infant Hospital Affiliated to Tongji University to confer the difference between residual group and non-residual group after 6 months of the LEEP conization.TCT,cervical biopsy and high risk HPV test were performed on all patients.RESULTS: Among 752 cases,57(7.6%)cases suffered HSIL residual disease while 695 cases in non-residual group. Before LEEP,HR-HPV 16/18 positive were less in HSIL lesion group showed no difference than those in non-residual group(P>0.05).The residual rate of post-LEEP specimens:CIS and invasive cancer identified only microscopically was higher than that in the AIS group(P<0.05).After LEEP,238 cases with positive margins and 514 cases with negative margins.The residual rate in patients with positive margin and negative margin were 21.1% and 1.4%,(P<0.05).The residual rate in patients with positive endocervical margin,ectocervical margin,unilateral margin and fibrous margin were28.7%,18.9%,17.2% and 26.3%,respectively(P<0.05). The residual rate in patients with second LEEP and non-second LEEP were 29.7% and 6.4%,respectively(P<0.05).The residual rate in patients with TCT≥ ASCUS and normal were 21.9% and 4.4%,respectively(P<0.05).Multivariate regression analysis using the logistic regression model showed CIS,abnormal cytology TCT≥ ASCUS and LEEP with positive margins to be independent risk factors for residual lesions after LEEP(P<0.05).CONCLUSION: Histopathology CIS after LEEP,abnormal cytology(TCT≥ ASCUS)and positive margin are predictors of residual lesion after LEEP with HSIL.
