Early clinical results of endoRectal surgery using a newly designed Rectal Tube with a side window
Surgical Endoscopy And Other Interventional Techniques, 2002Co-Authors: Eiji Kanehira, Kenji Omura, Takahiro Kinoshita, Kazuyuki Kawakami, Y. Yamashita, Go WatanabeAbstract:Background: Transanal endoscopic microsurgery (TEM) using the original Buess devices requires the use of a completely closed system for positive pressure gas insufflation. To simplify the setup of the system and expose the target lesion in the rectum without gas insufflation, we have developed a new operating Rectal Tube with a side window. Methods: The new Rectal Tube is a transparent cylinder measuring 40 mm in diameter with its forward end closed and a 40-mm opening on its side. When a Rectal tumor is captured within the opening, it can be clearly visualized without positive gas insufflation. Under endoscopic control, the lesion is then resected and the defect is closed by suturing. Using this new system, we performed endoRectal surgery on 10 patients with Rectal tumors. Our series included four benign adenomas, two carcinomas in situ, two T2 cancers, and two carcinoid tumors. Results: The operation was performed successfully in all 10 cases. There were no significant operative complications and the postoperative course was excellent in all cases. Pathological analysis revealed that the surgical margins of all specimens were completely free from tumor. Conclusions: Our early clinical results suggest that the newly designed operating Rectal Tube with a side window simplifies the endoRectal surgical procedure and facilitates the safe resection of Rectal tumors < 40 mm in diameter.

Development of a new operating Rectal Tube with a side window for transanal endoscopic surgery
Minimally invasive therapy & allied technologies : MITAT : official journal of the Society for Minimally Invasive Therapy, 2001Co-Authors: Eiji Kanehira, Kenji Omura, Takahiro Kinoshita, Kazuyuki Kawakami, K. Maeda, Go WatanabeAbstract:The authors describe a new Rectal Tube for use in transanal endoscopic surgery. The Tube is a transparent plastic sheath with its forward end closed, measuring 40 mm in diameter and 150 mm in insert length. It has a window, measuring 40 mm in diameter, on its side. The target lesion, captured within the side window, prolapses into the Rectal Tube and is excellently visualised without positive pressure gas insufflation. This paper gives details of the Tube and reports on a sessile Rectal tumour successfully treated using the new system.

Influence of Rectal Decompression on Abdominal Symptoms and AnoRectal Physiology following Colonoscopy in Healthy Adults.
Gastroenterology research and practice, 2016Co-Authors: Tso-tsai Liu, Wei-yi Lei, Jui-sheng Hung, Chien-lin ChenAbstract:Background. Postcolonoscopy abdominal discomfort and bloating are common. The aim of this study was to evaluate whether Rectal decompression improved distension-induced abdominal symptoms and influenced anoRectal physiology. Methods. In 15 healthy subjects, Rectal distension was achieved by direct air inflation into the rectum by colonoscopy. Placement of Rectal and sham Tube was then performed in each subject on a separate occasion. The anoRectal parameters and distension-induced abdominal symptoms were recorded. Results. AnoRectal parameters were similar between placements of Rectal Tube and sham Tube except for greater Rectal compliance with Rectal Tube than with sham Tube ( ). Abdominal pain and bloating were significantly reduced by Rectal Tube and sham Tube at 1 minute (both ) and 3 minutes (both ). After placement of Rectal Tube, abdominal pain at 3 minutes correlated positively with first sensation ( , ), and bloating at 3 minutes also correlated positively with urge sensation ( , ). Conclusions. Rectal decompression with either Rectal or sham Tube improved distension-induced abdominal symptoms. Our study indicates that the mechanisms that improved abdominal symptoms by Rectal decompression might be mediated by a central pathway instead of a peripheral mechanism.

Comparison of Rectal suction versus Rectal Tube insertion for reducing abdominal symptoms immediately after unsedated colonoscopy.
Endoscopy international open, 2015Co-Authors: Tso-tsai Liu, Wei-yi Lei, Jui-sheng Hung, Chien-lin ChenAbstract:Background and study aims: Abdominal discomfort and bloating are common symptoms after colonoscopy. We aimed to compare the effects of direct Rectal suction with insertion of a Rectal Tube on reducing abdominal symptoms after unsedated colonoscopy. Patients and methods: Consecutive patients undergoing colonoscopy were randomized to have direct Rectal suction or placement of a Rectal Tube immediately after colonoscopy. Post-procedure abdominal pain and bloating were measured with a 0 – 100 visual analogue scale. All participants ranked their satisfaction with either direct Rectal suction or insertion of a Rectal Tube. Results: Abdominal pain and bloating were significantly reduced by direct Rectal suction and placement of a Rectal Tube at 1 minute (both P P P = 0.001) and 3 minutes ( P = 0.005) after colonoscopy compared with Rectal Tube insertion. Bloating was significantly lower in patients with direct Rectal suction compared to those with Rectal Tube insertion at 1 minute ( P = 0.03) after colonoscopy. Greater satisfaction was found in patients with direct Rectal suction compared to those with Rectal Tube insertion ( P = 0.009). Conclusion: Direct Rectal suction is more effective than Rectal Tube placement in reducing abdominal symptoms immediately after colonoscopy. Our study suggests that direct Rectal suction is useful in providing relief of symptoms when patients are having difficulty expelling air or are experiencing abdominal symptoms following colonoscopy.

Colonoscopically guided Tube decompression in Ogilvie's syndrome.
Diseases of the colon and rectum, 1991Co-Authors: Joaquin Sariego, Teruo Matsumoto, Morris D. KersteinAbstract:Ogilvie's syndrome (pseudo-obstruction of the colon) may result in gangrene and perforation of the colon if not effectively treated. Colonoscopic decompression and endoscopically guided Rectal Tube placement were employed to treat five patients with this syndrome who had failed medical therapy. All patients tolerated the procedure well and required no further treatment.
