A Case of Adenosquamous Carcinoma of the Gallbladder with Anomalous Arrangement of the Pancreaticobiliary Ductal System.

The Japanese Journal of Gastroenterological Surgery (1998)

Atsushi Adachi T Toshimitsu Toshihiro Saeki T. Uchiyama T Murakami

膵胆管合流異常に合併した胆嚢腺扁平上皮癌症例を経験したので報告する.症例は67歳の女性.上腹部痛を主訴とし, 血液検査では肝酵素異常を示すのみであった.腹部US, CT, MRIで胆嚢体部に内腔に突出する腫瘍を認めた.ERCPでは新古味分類IIbの膵胆管合流異常があり, 肝外胆道, 胆嚢管の拡張を認めた.術中の胆嚢内, 胆道内胆汁細胞診にて腺扁平上皮癌の診断を得, リンパ節郭清を伴う膵胆管合流部から肝門部の胆管切除, 肝床切除を伴う胆嚢摘出, 胆管空腸吻合を施行した.腫瘍はGb, hep, 結節浸潤型で, 病理組織ではss, hinf1α, binf0, t2, bm0, hm0, em0, n1 (+), stage 2, 中分化型の腺扁平上皮癌であった.そして, 腺癌と深部の扁平上皮癌の間に移行像を認め, 扁平上皮癌化生説を支持するものであった.また, 転移リンパ節は, ほとんどが扁平上皮癌であり, 予後不良を予感させた.胆管内のamylaseは高値を示し, 胆嚢癌発生の1因と考えられた.

Silicone Breast Implant Rupture Triggered by Infection Leading to Skin Ulceration: A Case Report

Cureus (2024)

Yoshika Nagata Shinichi Sezaki Izumi Kinoshita Toshihiro Saeki Takahisa Fujikawa

Silicone breast implants (SBIs) are commonly used for breast reconstruction and cosmetic surgery. However, long-term complications associated with SBI, such as rupture and infection, require careful monitoring. Here, we report a case in which coronavirus disease 2019 infection led to immunosuppression and secondary bacterial infection, resulting in skin ulceration and eventual removal of the SBI. This case highlights the potential complications of long-term use of SBI and the need for careful postoperative monitoring.

A CASE OF SYNCHRONOUS TRIPLE EARLY CANCERS OF THE ESOPHAGUS, STOMACH AND COLON WITH CURATIVE RESECTION

Nihon Rinsho Geka Gakkai Zasshi (Journal of Japan Surgical Association) (2006)

Toshihiro Saeki Ryoichi Shimizu Yoshinari Maeda

同時性に認められた食道,胃,大腸の3重複早期癌を根治的に切除しえた症例を経験したので報告する.症例は60歳の男性で,検診にて便潜血を指摘され,近医受診し,胃内視鏡検査にて,胃癌と診断された.手術目的で当科に紹介された.術前検査として他病変の有無を精査した結果,食道癌および大腸癌の重複が判明した.治療は,いずれも早期癌であり,食道癌と大腸癌に対しては,内視鏡的粘膜切除術を行い,胃癌に対しては,胃全摘術を選択した.組織学的には,各腫瘍とも深達度mもしくはsmの早期癌であり,発生部位と発生時期から同時性3重複癌と考えられた.術後経過は良く,第49病日に退院した.術後2年7カ月を経過した現在,再発を認めていない.食道,胃,大腸の3重複早期癌は1990年から2004年までに本邦報告は,自験例を含め20例であった.癌症例では重複癌を常に念頭においた術前全身精査と術後長期にわたる検査加療が必要である.

[Clinicopathological studies on cases of multiple primary carcinomas of the esophagus associated with carcinoma of the hypopharynx and cervical esophagus].

PubMed (1986)

Wataru Takiyama Y Yamaguch Toshihiro Saeki S Takashima Shoichiro Koike

Four cases of multiple primary carcinoma of the esophagus associated with dysplasia were found among seven patients with squamous cell carcinoma of the hypopharynx and cervical esophagus at the Shikoku Cancer Center Hospital. Two minute carcinomas were observed in these cases. One of them was too small to detect clinically despite the application of esophagoscopy with the Lugol's solution spraying method. All four patients had continued to smoke and consume alcoholic beverages (regularly) (habitually). These findings suggested that total esophagectomy is applicable to patients with hypopharyngoesophageal cancer, particularly those who continue to drink and smoke regularly.

A CASE OF CECAL VOLVULUS DIAGNOSED BEFORE SURGERY

Nihon Rinsho Geka Gakkai Zasshi (Journal of Japan Surgical Association) (2004)

Yasunori Yoshimoto Ryoichi Shimizu Toshihiro Saeki Toshio HARADA Yoshinari Maeda

術前診断できた盲腸軸捻症の1例を経験した.症例は74歳,男性.腹痛を主訴に近医を受診,イレウスの診断で治療中に腹部膨隆が著明となり紹介となった. X線検査,腹部CT検査より右側結腸軸捻転症と診断し,腹部所見が軽度であったため,まず大腸内視鏡での整復を試みた.上行結腸にて完全に閉塞しており,内視鏡より造影剤を注入するとbird's beak signが認められた.内視鏡的に整復は困難であったため,盲腸軸捻症による腸閉塞の診断で手術を施行した.開腹すると穿孔部はなく,盲腸部は腸間膜を中心に時計周りに180度捻転し小腸が盲腸の尾側より右傍結腸溝に入り込んでいた.腸管を整復,減圧したところ,腸管の色調が回復したため腸切術をせず,盲腸・上行結腸を後腹膜に固定し手術を終了した.術後問題なく退院,現在まで再発は認めていない.

Lower and Middle Bile Duct Cancer that was Difficult to Differentiate from Benign Biliary Stenosis after Cholecystectomy. A Case Report.

Nihon Rinsho Geka Gakkai Zasshi (Journal of Japan Surgical Association) (2001)

Yasunori Yoshimoto Ryoichi Shimizu Toshihiro Saeki Hideto Hayashi Toshio HARADA

症例は46歳男性.初回入院時亜急性胆嚢炎に対し,開腹胆摘術を施行した.術中胆道造影では総胆管の軽度変形はあるものの急性炎症の波及によるものと判断した.術後3カ月目に閉塞性黄疸のため入院,精査後,胆摘に伴う良性胆道狭窄症の診断にて手術を行った.術中迅速でリンパ節転移陽性の胆管癌と診断されたため, PpPDを施行した.病理学的には粘膜下を中心とし神経浸潤の著明な中分化型腺癌であった.胆嚢摘出術3カ月で胆道狭窄をきたし,良悪性の判断に難渋した症例を経験した.胆道狭窄症例に直面したときには,容易に非観血的治療を選択することなく,悪性疾患の可能性も十分に考慮した適切な治療法を選択しなければならないと思われた.

When no other non-curative treatment options are available, R0 resection can be achieved with paraaortic lymphadenectomy for patients with advanced gastric cancer with No.16 lymph node metastases. Herein, we report of a patient who underwent R0 resection for gastric cancer with No.16 lymph node metastases and who achieved long-term survival.
