Heterochronous Suture Line Recurrences in the Jejunal Pouch following Total Gastrectomy for Stage II Gastric Cancer: A Case Report and Literature Review.

Case Rep Oncol 2020 Jan-Apr;13(1):225-232. Epub 2020 Mar 19.

Department of Surgery, Tokyo Dental College Ichikawa General Hospital, Ichikawa, Japan.

We report the case of a 65-year-old male who developed heterochronous local recurrences of gastric cancer in the jejunal pouch (J-pouch) four times after total gastrectomy. He underwent total gastrectomy, J-pouch, and Roux-en-Y reconstruction for stage II gastric cancer in 2005. Four local recurrences appeared on the esophago-jejunal anastomosis, the suture line within the pouch, the esophago-jejunal anastomosis, and the anastomosis between the jejunum and Y-loop, which were resected by partial excision or endoscopic submucosal dissection. Suture line recurrence of gastric cancer is rare. The common features for each recurrence included the surgically negative resection margins, observation of the same histopathological subtype, absence of remote metastasis or peritoneal seeding, and the recurrence on the anastomotic suture line, suggesting that the cause of recurrence was the implantation of exfoliated cancer cells probably in the suture line. However, there is no established procedure for preventing implantation recurrence currently, the effectiveness of lumen lavage is suggested.

Evolution of surgery for rectal cancer: Transanal total mesorectal excision~new standard or fad?~.

J Anus Rectum Colon 2018 29;2(4):115-121. Epub 2018 Oct 29.

Transanal Total Mesorectal Excision (TaTME) has recently been developed to overcome the difficulties associated with conventional laparoscopic or robotic TME. TaTME has gained popularity and becomes the center of attention among colorectal surgeons globally. The present review aims to update the literature, clarify the current status and perspectives of TaTME. Complete TaTME specimens were obtained in 85-97.1% of the case; the reported circumferential resection margin (CRM) ranged from 1.5% to 8.1%, whereas and distal resection margin (DRM) positive rates ranged from 0% to 3.2%. The conversion rate of TaTME occurred from 0 to 15%, and there was no difference between TaTME and laparoscopic or robotic TME. Intraoperative complications occurred in 5-6% of the case, which compared favorably to laparoscopic TME. The most serious intraoperative complication with this approach was urethral injury, although only small numbers were reported, which was possibly due to under-reporting. Clavien-Dindo I or II postoperative complications occurred in 22-24% of the case, and III or IV in 10-11% of the case, which did not differ between TaTME and laparoscopic or robotic TME. TaTME may be technically easier and more beneficial than laparoscopic, robotic or open TME in male patients with a narrow pelvis; in obese patients with a bulky tumor. At present two randomized controlled trials, COLOR III and GRECCAR, and comparing TaTME with laparoscopic TME are being conducted and their outcomes are awaited. TaTME is a complex procedure, but proved to be feasible, oncologically safe, and effective in difficult cases. Before this new technique is adopted, proper training with Proctor/mentorship is strongly advised. Careful case selection and audit of data are mandatory.

Successful treatment of esophagopleural fistula following pulmonary resection for primary lung cancer: a case report.

Surg Case Rep 2019 May 14;5(1):78. Epub 2019 May 14.

Department of Surgery, Tokyo Dental College Ichikawa General Hospital, 5-11-13 Sugano, Ichikawa, Chiba, 272-8513, Japan.

Background: We report a rare case of esophagopleural fistula (EPF) developing during the postoperative period after pulmonary resection for primary lung cancer.

Case Presentation: A 71-year-old male who underwent video-assisted thoracoscopic right lower lobectomy with lymph node dissection for primary lung cancer developed severe stabbing pain in his right shoulder and high fever 3 days after the operation. The fever persisted, the cough became more productive, and a plain chest X-ray showed slight a few infiltrative opacities in the right lung field. Intravenous antibiotic therapy was initiated. The patient developed a right pneumothorax 5 days after the operation, and contaminated discharge from the right chest tube was noted. A chest computed tomography showed right-sided empyema, while bronchoscopic examination revealed no evidence of a bronchopleural fistula. Open-window thoracostomy (OWT) was performed. Finally, 2 days after the OWT, the patient was diagnosed as having an EPF, because the right chest cavity was found to be contaminated with food materials. Ample purification of the right chest cavity was achieved by repeated dressing changes, and the EPF was finally closed by omentopexy. The post-surgical course was uneventful. Five weeks after the omentopexy, an esophagogram revealed no leakage of the contrast medium from the esophageal wall. The patient was discharged 13 weeks after the omentopexy.

Conclusion: While EPF following pulmonary resection is a rare complication, it can lead to critical situations and the diagnosis is difficult. Prompt OWT and omentopexy were found to be effective treatment procedures for EPF following lung surgery.

[A case of bone marrow carcinomatosis from breast cancer treated with weekly Paclitaxel].

Gan To Kagaku Ryoho 2012 Jan;39(1):99-101

Dept. of Surgery, Tokyo Dental College Ichikawa General Hospital.

We report a case of bone marrow carcinomatosis originating from breast cancer that was treated with weekly paclitaxel (PTX). A 42-year-old female patient underwent mastectomy with axillary lymph node dissection for breast cancer in 2001. Multiple bone metastases were diagnosed in 2008, but she remained stable with chemotherapy and hormonal therapy for about two years. In 2010, thrombocytopenia occurred, and she was diagnosed with bone marrow carcinomatosis after bone marrow biopsy. She was treated with weekly PTX(80 mg/m2), and recovered successfully after treatment. About one year has elapsed since initiation of therapy, and there has been no recurrence. Bone marrow carcinomatosis originating from breast cancer is very rare, and is regarded as a disease with a poor prognosis. However, weekly PTX could be a valid treatment for prolonging survival of bone marrow carcinomatosis originating from breast cancer.

[Efficacy of treatment with high-dose toremifene in patients with metastatic breast cancer resistant to aromatase inhibitor treatment].

Gan To Kagaku Ryoho 2009 Jun;36(6):1013-6

Dept. of Surgery, Sougo Oota Hospital, Japan.

The efficacy of aromatase inhibitors(AI)has been established for adjuvant and metastatic breast cancer. However, decision making regarding treatment becomes difficult after AI treatment. Recently, high-dose toremifene(HD-TOR, TOR 120 mg daily)showed efficacy in these patients. We attempted to study retrospectively the efficacy and safety of HD-TOR treatment. Seven patients received HD-TOR. The overall response rate was 29%(PR 2)and clinical benefit (CR, PR, long SD)was 57%(PR 2, long SD 7). HD-TOR may be an optional treatment for MBC after AI treatment.
