| 1 | Endoscopic features of early-stage signet-ring-cell carcinoma of the stomach显示文摘AIM: To identify the features of early signet ring cell gastric carcinoma using magnification endoscopy with narrow band imaging(NBI).METHODS: A retrospective review was conducted of 12 cases of early signet ring cell gastric carcinoma who underwent treatment in a single institution between January 2009 and April 2013. All patients had magnification endoscopy with NBI and indigo carmine contrast to closely examine the mucosal architecture, including the microvasculature and arrangement of gastric pits. Histologic examination of the final endoscopic submucosal dissection or gastrectomy specimen was performed and compared with the endoscopic findings to identify patterns specific to signet ring cell carcinoma.RESULTS: Twelve patients with early signet ring cell gastric carcinoma were identified; 75% were male, and average age was 61 years. Most of the lesions were stage T1a(83%), while the remainder were T1b(17%). The mean lesion size was 1.4 cm2. On standard endoscopy, all 12 patients had a pale, flat lesion without any evidence of mucosal abnormality such as ulceration, elevation, or depression. On magnification endoscopywith NBI, all of the patients had irregularities in the glands and microvasculature consistent with early gastric cancer. In addition, all 12 patients exhibited the 'stretch sign', an elongation or expansion of the architectural structure. Histologic examination of the resected specimens demonstrated an expanded and edematous mucosal layer infiltrated with tumor cells.CONCLUSION: The 'stretch sign' appears to be specific for signet ring cell carcinoma and may aid in the early diagnosis and treatment of this aggressive pathology. | Chainarong Phalanusitthepha Kevin L Grimes Haruo Ikeda Hiroki Sato Chiaki Sato Chananya Hokierti Haruhiro Inoue | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，7： | 8 |
| 2 | Is fascial closure required for a 12-mm trocar?A comparative study on trocar site hernia with long-term follow up显示文摘BACKGROUND Despite the infrequency of trocar site hernias(TSHs),fascial closure continues to be recommended for their prevention when using a≥10-mm trocar.AIM To identify the necessity of fascial closure for a 12-mm nonbladed trocar incision in minimally invasive colorectal surgeries.METHODS Between July 2010 and December 2018,all patients who underwent minimally invasive colorectal surgery at the Minimally Invasive Surgery Unit of Siriraj Hospital were retrospectively reviewed.All patients underwent cross-sectional imaging for TSH assessment.Clinicopathological characteristics were recorded.Incidence rates of TSH and postoperative results were analyzed.RESULTS Of the 254 patients included,70(111 ports)were in the fascial closure(closed)group and 184(279 ports)were in the nonfascial closure(open)group.The median follow up duration was 43 mo.During follow up,three patients in the open group developed TSHs,whereas none in the closed group developed the condition(1.1%vs 0%,P=0.561).All TSHs occurred in the right lower abdomen.Patients whose drains were placed through the same incision had higher rates of TSHs compared with those without the drain.The open group had a significantly shorter operative time and lower blood loss than the closed group.CONCLUSION Routine performance of fascial closure when using a 12-mm nonbladed trocar may not be needed.However,further prospective studies with cross-sectional imaging follow-up and larger sample size are needed to confirm this finding. | Santi Krittiyanitsakun Chawisa Nampoolsuksan Thikhamporn Tawantanakorn Tharathorn Suwatthanarak Nicha Srisuworanan Voraboot Taweerutchana Thammawat Parakonthun Chainarong Phalanusitthepha Jirawat Swangsri Thawatchai Akaraviputh Asada Methasate Vitoon Chinswangwatanakul Atthaphorn Trakarnsanga | 2023 | World Journal of Clinical Cases2023，11，2： | 1 |
