Diagnostic Cone Biopsy : A Modified Surgical Technique, Diagnostic Agreement and Surgical Result (Konisasi Diagnostik : Modifikasi Cara Pembedahan, Kesesuaian Diagnostik dan Hasil Pembedahan)
A modified cervical cone without hemostatic suture has been done using 10 cc of 20 pressor unit/cc vasopressin in 50 cc lidocaine (HCl 2 percent or NaCl 0.9 percent which is given intracervically. This study was held for over 4 years beginning November 1, 1990 through October 31, 1994. The objective of this study was to find a more simple and faster surgical techniques, to find the correlations among diagnostic modalities and to find the surgical complications especially the bleeding. Cone biopsy indications were 41.7 percent due to lesion inside the cervical canal, 33.3 percent disagreement between cytology and histology, 16.7 percent abnormal cytology without prominent colposcopic lesion, and 8.3 percent suspicious of invasive cancer on cytology. Concordance of diagnoses (Kappa) in detecting the low and high grade lesions were not good, -0.36 and 0.08. Specimens from cone biopsies were measured and had their means of 2.8 plus/minus 0.4 cm in height and bottom's diameter of 2.1 plus/minus 0.7 cm, amount of bleeding was 1.4 plus/minus 0.8 cc, and duration of operation was 7 plus/minus 2.4. Pregnancy has been occured in 12.5 percent of cases, 2 were aterm and one of them was delivered spontaneously, 1 miscattiage on 10 weeks of pregnancy. Conclusions : This modified cone biopsy proved to be simple, faster, less bleeding, but has no good agreement among diagnostic modalities.
