Impact of clinicopathological variables on laparoscopic hysterectomy complications, a tertiary center experience.

OBJECTIVES: To analyze intraoperative and postoperative complications according to Clavian-Dindo Classification (CDC) and evaluate the influence of clinicopathological features on the feasibility and safety of total laparoscopic hysterectomy (TLH) in patients that underwent surgery in a tertiary center. MATERIAL AND METHODS: We retrospectively reviewed the database of 469 patients that underwent surgery for patients who underwent extra facial TLH from 2013 to 2020. RESULTS: A total of 86 (18.3%) peri-postoperative complications were observed. The incidence of intraoperative complications was 2% (n = 10). The overall conversion rate to open surgery was 1.9% (n = 9). A total of 76 postoperative complications were observed in 61 patients (14.3%). The incidence of minor (Grade I [n = 16, 3.4%] and II [n = 42, 8.9%]) and major complications (Grade III [n = 15, 3.2%], IV [n = 2, 0.4%] and V [n = 1, 0.2 %]) were 12.3% and 3.8%, respectively. A higher BMI and performing surgery at the first step of learning are found to be associated with intraoperative and postoperative complications (p < 0.05). Postoperative complications related to having a history of the cesarean section, additional comorbidities, and uterine weight ≥ 300 g (p < 0.05). CONCLUSIONS: The implementation of TLH by experienced surgeons appears to have remarkable advantages over open surgery. However, the risk factor for complications should be taken into account by surgeons in the learning curve in selecting the appropriate patient for surgery.

[Detection and typing of human papilloma virus by polymerase chain reaction and hybridization assay in cervical samples with cytological abnormalities]. / Sitolojik atipi izlenen servikal örneklerde insan papilloma virusunun polimeraz zincir reaksiyonu ve hibridizasyon yöntemleriyle saptanmasi ve tiplendirilmesi.

Certain mucosa-tropic human papillomavirus (HPV) types are associated with carcinoma of the uterine cervix or its precursor lesions. In addition to cytological screening, early diagnosis and treatment of cervical carcinoma rely on sensitive detection and typing of HPV isolates. In this study, HPV detection and typing were performed in the cervical samples of patients with abnormal cytological evaluation. Forty randomly-selected cervical samples that comprise 18 ASC-US (Aypical Squamous Cells of Undetermined Significance), four AG-US (Aypical Glandular cells of Undetermined Significance), one ASC-H (Atypical Squamous Cells-can not exclude HSIL), one HSIL (High-grade Intraepithelial Lesion), 14 LSIL (Low-grade Intraepithelial Lesion), one adenocarcinoma and one squamous cell carcinoma, obtained by a commercial liquid-based cytology system (ThinPrep Pap Smear Method, Cytyc, USA), were included to the study. HPV-DNA detection were accomplished by L1 in-house polymerase chain reaction (PCR) performed using MY09/11 and GP5/6 primers along with a commercial real-time PCR (HeliosisTM HPV LC PCR Kit; Metis Biotechnology, Turkey) that detects HPV infections and HPV-16 via melting curve analysis. A commercial PCR-array hybridization test (Rapid HPV Genotyping MacroArray; HybriBio Inc, Hong Kong) that can identify 21 low and high risk HPV types was employed for typing. Viral DNA was detected in 35% (14/40) and 57.5% (23/40) of the samples by MY09/11 and GP5/6 primers, respectively. All in-house PCR positive samples were also positive in the real-time PCR assay. PCR-array hybridization assay provided typing results in 95.6% (22/23) of the PCR positive samples while one LSIL sample could not be typed by any of the methods used. High risk HPV types 16, 18, 31, 45, 52, 56, 58, 59,68 (65.8%); probable high risk type 53 (13.2%), low risk types 6, 42 and 81 (21%) were identified out of a total of 38 HPV isolates. Multiple infections with more than one HPV type were identified in 45.5% (10/22) of positive samples. High/probable high risk types were detected in all single infections and all low risk isolates were present in multiple infections. HPV-16 was identified in 31.8% (7/22) by real-time PCR and in 45.5% (10/23) of positive samples by PCR-array hybridization assay. HPV-16 was observed to be the most frequently detected type (10/22, 45.5%), followed by types 53 and 81 (5/22, 22.7%); 68 (4/22, 18.2%); type 58 (3/22; 13.6%); types 31, 42 and 59 (2/22; 9.1%) and others (1/22, 4.5%). As a result our data have indicated the abundance of high risk HPV isolates and infections with multiple HPV types in that specific area.

[Human papilloma virus DNA in cervical samples with cytological abnormalities and typing of the virus]. / Sitolojik olarak anomali saptanan serviks örneklerinde insan papilloma virus DNA'sinin arastirilmasi ve virusun tiplendirilmesi.

Human Papillomavirus (HPV) infections and cervical carcinoma which is associated with certain types of the virus have been worldwide public health issue. Early diagnosis of HPV infections and the detection of viral genotypes are important for the successful treatment and prevention of cervical carcinoma. This study has been designed as a preliminary study to estimate HPV type distribution in cervical samples with cytologic abnormalities in our country. A total of 35 cervical samples which were evaluated by a commercial liquid-based cytological system, were included to the study. The presence of HPV-DNA has been searched with nested polymerase chain reaction (PCR) by using consensus primer sets of MY09/11 and GP5/6 that target L1 region of the viral genome. HPV typing was performed by direct sequencing of the amplicons. In cytologic evaluation, 14 samples were diagnosed as ASC-US (Aypical squamous cells of undetermined significance), three were ASC-H (Atypical squamous cells-cannot exclude HSIL), five were HSIL (High-grade intraepithelial lesion), seven were LSIL (Low-grade intraepithelial lesion), four were LSIL+suspected HSIL, one was AG-US (Aypical glandular cells of undetermined significance) and one was atypical cells of undefined nature. HPV-DNA was detected in 28 of the 35 (80%) samples, and sequence analysis revealed high-risk HPV types (type 16, 18, 31, 33, 45, 56, 59) in 22 (78.6%) samples, probable high-risk types (type 53) in two (7.1%) samples and low-risk types (type 6, 54, 72, 81) in four (14.3%) samples. HPV type 16 emerged as the most frequently-detected type, comprising 50% (14/18) of all samples; followed by type 18 in 10.7% (3/28) and type 53 in 7.1% (2/28) of the samples. As a result, although the number of cervical samples were relatively low, the preliminary data obtained with this study revealed the HPV type distribution, however more detailed studies are needed to elucidate the epidemiology of HPV infections in Turkey.
