Solitary distant peritoneal metastasis of cecal cancer after laparoscopic colectomy : a case report
A 77-year-old Japanese female underwent laparoscopic ileocecal resection and lymph node dissection for cecal cancer by a previous doctor. Two years and 9 months after previous operation, contrast-enhanced computed tomography and magnetic resonance imaging with gadolinium ethoxybenzyl-L-diethylenetriamine pentaacetic acid revealed an intraperitoneal tumor at the right subphrenic fossa. 18F-fluorodeoxyglucose position emission tomography showed fluorodeoxyglucose accumulation in the tumor, and we suspected the tumor to be solitary distant peritoneal metastasis of the previous cecal cancer to the right diaphragm. We performed partial diaphragmectomy and direct closure, and pathological examination revealed moderately differentiated tubular adenocarcinoma resembling the previous cecal cancer, which seemed to be disseminated metastasis in the pathological features. Based on the intraoperative findings, we assumed the tumor to be solitary distant peritoneal metastasis caused by procedures during the previous laparoscopic operation. The present report suggests the importance of paying close attention to procedures during laparoscopic colorectal resection to prevent peritoneal seeding
Coincident Port-site and Functional End-to-end Anastomotic Recurrences after Laparoscopic Surgery for Colon Cancer : A case report and literature review
Herein, we report coincident recurrences at the port site and functional end-to-end anastomosis after laparoscopic right hemicolectomy for cancer of the ascending colon. The patient was an 83-year-old man who had undergone the aforementioned procedure (Stage IIA) in the referral hospital. At the 10-month follow-up, computed tomography showed two tumours around 3 cm in diameter : one on the right-flank abdominal wall-the surgical port-site-and the other at the functional end-to-end anastomosis. Likewise, a positron emission tomography scan was positive for two tumours. Endoscopic examination showed an ulcerated tumour with a clear margin, and a biopsy confirmed moderately differentiated tubular adenocarcinoma. The patient was diagnosed with coincident recurrences at the port site and functional end-to-end anastomosis after laparoscopic right hemicolectomy for cancer of the ascending colon. We re-operated inMarch 2016. The tumours at the functional end-to-end anastomosisand functional end-to-end anastomosiswere resected. After 7 months, no recurrence was detected
