Laparoscopic bilateral salpingo-oophorectomy for women aged 70 and older

JAPANESE JOURNAL OF GYNECOLOGIC AND OBSTETRIC ENDOSCOPY (2015)

Taeko Ueda Atsushi Tohyama Hitomi Nakagawa Teppei Higashi Yukiyo Aiko

Objective: We retrospectively assessed perioperative risk for laparoscopic salpingo-oophorectomy in elderly women.Design: We performed 13 laparoscopic salpingo-oophorectomy procedures in women aged 70 and older. During the same period, 18 patients aged 45 to 59 also underwent bilateral laparoscopic salpingo-oophorectomy. We defined the latter group of patients as the control group. We compared the older group with the control group with regard to underlying diseases, preoperative evaluations, surgical methods, intraoperative complications, postoperative complications, and hospitalization.Results: The median age of the older patients was 74 years (range, 70-83 years). Ten of the 13 older patients had an underlying disease. Three patients were obese (Body Mass Index > 25). Four patients received perioperative anticoagulant therapy. All of the tumors were benign in the final pathological diagnosis. For the laparoscopic procedure, abdominal air pressure was fixed at 8 mmHg. All of the patients underwent surgery only under general anesthesia. The average duration of the operation was 110 min (range, 46-110 min). Average blood loss was 16 ml (range, 0-140 ml). No perioperative complications were observed. All of the patients began walking 1 day after surgery. The median inpatient hospital stay was 4 days (range, 3-7 days). Two patients had subcutaneous hematoma as a postoperative complication, which did not need any treatment or postponement of hospital discharge. Comparisons between the older group and control group revealed that only the rate of underlying disease was significantly different.Conclusion: Laparoscopic salpingo-oophorectomy for aged women must be conducted cautiously because such patients have a high prevalence of underlying disease. Almost all of the procedures were conducted safely, suggesting that this surgical indication could be expanded for aged women.

Management of severe dysplasia and carcinoma in situ (CIS) during pregnancy.

過去8年間に当科で施行した妊婦に対する子宮頸部擦過細胞診より異常細胞診率, 子宮頸部初期病変発見率を検討した. また, 子宮頸部高度異形成および上皮内癌症例について症例を呈示するとともに, 妊娠中の子宮頸部初期病変の診断上の注意点やfollow up成績について検討した.1. 過去8年間の妊婦における異常細胞診発見率は, 1.5%であった.また, コルポスコピーおよび生検による精査で子宮頸部初期病変と診断されたのは, 0.82%であった.2. 子宮頸部高度異形成および上皮内癌の症例は8例みられたが, 7例において組織診が, 細胞診に対してover diagnosisであった. また, 5例に多数の腺管侵襲が認められた.3. 子宮頸部高度異形成および上皮内癌の8例中6例が分娩後に消失した. 消失の原因については種々の要因が考えられるが, 生検のover diagnosisが最も大きな要素ではないかと考えている.4.妊婦に子宮頸部初期病変が検出される率は, 非妊婦と比較してほぼ同等である. よって, 妊婦検診においても子宮癌検診を徹底し, 異常細胞診症例に対しては, コルポスコピー下に生検を施行し, 精査・厳重な管理が必要である.

[Disorder of serum electrolytes following CAP therapy].

PubMed (1991)

Yusuke Matsuura Mari L. Shinohara M Kashimura Shozo Baba H Otsuka

Combination chemotherapy with Cyclophosphamide, Adriamycin and Cisplatin (CAP) is one of the most effective chemotherapies for ovarian cancer. Severe vomiting induced by this treatment may cause a disorder of the serum electrolytes. Severe hyponatremia was observed in one patient who complained of convulsions and unconsciousness. Accordingly we studied the disorder of serum electrolytes in 158 courses of CAP treatment (44 patients) during the five years from 1984 to 1988. The serum electrolytes were influenced by the amount of vomiting in this study. Consequently frequent examination of serum electrolytes is necessary during this treatment.

New diagnostic criteria of colposcopy for uterine cervix neoplasia

Journal of Obstetrics and Gynaecology Research (2016)

Masamichi Kashimura Yusuke Matsuura Toshinori Kawagoe Naoyuki Toki Toru Hachisuga

The purpose of this study is to present alternative diagnostic criteria of colposcopy using new parameters.Colposcopic photographs were reviewed in 1649 patients from the past 23 years, including 283 benign lesions, 327 low-grade squamous intraepithelial lesions (LSIL; cervical intraepithelial neoplasia 1), 549 high-grade squamous intraepithelial lesions (HSIL; cervical intraepithelial neoplasia 2/3), 78 microinvasive cancers, and 412 invasive cancers. Abnormal colposcopic findings were divided into: minor or major; single, or a combination of two or three findings; and under half or over half circumferential size. Histopathological backgrounds were investigated according to these new parameters of colposcopic findings.Minor abnormal colposcopic findings were observed in 21% of LSIL, and major abnormal findings were seen in 52% of LSIL, 86% of HSIL, and 86% of microinvasions. A single major abnormal finding was observed in 64% of the cases with LSIL, while two abnormal findings were observed in 43% of HSIL, and three abnormal findings were observed in 44% of microinvasions. In qualifying major abnormal colposcopic findings, under half size was detected in 91% of LSIL and 74% of HSIL, and over half size was observed in 58% of microinvasions. From these results, the following diagnostic criteria were instituted: (i) LSIL - single, minor or major findings and under half size; (ii) HSIL - two or three major findings and under half size; (iii) microinvasion - three major findings and over half size; and (iv) invasive cancer - irregular surface with atypical vessels.Our new diagnostic criteria of colposcopy are fully acceptable, based on their similar level of accuracy to cytology.

Cytological and pathological study of 3 cases of carcinosarcoma of the uterine body.

The Journal of the Japanese Society of Clinical Cytology (1999)

子宮体部悪性腫瘍のうち, 子宮肉腫の占める割合は約5%と比較的まれな疾患であるが, 術前に正確な診断を得ることが困難なことも多い. 今回われわれは, 過去1年間に癌肉腫3例 (肉腫成分同所性2例, 肉腫成分異所性1例) を経験したので細胞診による術前診断の可能性について検討した. 症例は54歳, 56歳, 64歳ですべて閉経後に認められ, 全例不正出血の症状があったが, 子宮頸部擦過細胞診が陽性であったのは非上皮性異型細胞が出現していた1例のみであった. 内膜細胞診では腺癌・肉腫細胞ともに出現していたのが1例, 肉腫成分のみが出現していたのが1例, 腺癌のみ出現していたのが1例であった. また, 術前の内膜組織診と最終診断が一致したのは3例中1例のみであった. 摘出子宮における捺印細胞診ではそれぞれ組織像に類似した悪性細胞が出現していた. また, 特殊染色を各症例に施行したが, 肉腫細胞に上皮性のマーカーが陽性になることもあり, 必ずしも有用とは判断されなかった.子宮体部非上皮性悪性腫瘍の診断にあたっては, 臨床所見や腫瘍の肉眼的所見を含めて慎重に対処することが必要である.

Clinicopathological analysis of uterine cervical cancer in young women-Significance of cervical cancer screening-

The Journal of the Japanese Society of Clinical Cytology (2004)

目的:当科で経験した若年者子宮頸癌症例を検討し, 若年者に対する子宮頸がん検診の意義を明らかにする.方法:過去18年間に当科で初回治療を行った子宮頸癌症例662例 (40歳以上536例・30歳代111例・20歳代15例) を対象に臨床進行期・病理組織型・がん検診受診歴を中心にretrospectiveに検討した. また, 30歳未満の15例については治療を含めた臨床所見について検討した. 統計学的有意差検定にはx2検定を用いた.成績:40歳未満の上皮内癌症例は頸癌126例中64例 (51%) であり, 40歳以上の頸癌536例中99例 (18%) に比較して有意に上皮内癌の占める割合が高かった (p<0.0001). 病理組織型については40歳以上・未満で有意な差は認めなかったが, 上皮内腺癌はすべて40歳未満の症例に認められた. 3年以内の検診受診歴がある者は40歳未満で31%, 40歳以上では23%であり, 両者間で有意な差を認めなかったが, がん検診受診歴のない症例では有意に進行癌の割合が多かった (p<0.0001). 30歳未満の症例15例中8例は上皮内癌であったが, 7例は浸潤癌 (1a1期3例, 1b1期・2a期・2b期・3b期各1例) であり, 浸潤癌症例のうち, がん検診受診歴がある者は1例のみであった.結論:若年者の子宮頸癌では初期癌が多い傾向にあり, 妊婦をはじめ産婦人科受診者に対しては積極的に子宮がん検診を施行することが重要である. また, 20歳代でも30歳代と同率の浸潤癌症例がみられたことから考えて検診対象者の年齢に対する検討も必要である.
