From 1987 to 1991, we performed intraoperative colonoscopy on 66 patients as a result of the following indications: the air leakage test (53%), detection of a previous malignant polypectomy site (20%), inability to complete preoperative colonoscopy (17%), detection of the source of intestinal bleeding (4%), and detection of impalpable colonic lesions (4%).(More)
This study evaluated the postoperative complications and clinical results of restorative proctocolectomy without diverting ileostomy for ulcerative colitis. One hundred selected patients had a hand-sewn ileal J-pouch anal anastomosis with mucosectomy using an ultrasonically activated scalpel. Three patients with pouch-related complications who needed(More)
The aim of this study was to determine the postoperative function of neorectoanal components using two different types of very low coloanal reconstruction. The two groups of patients assessed were 22 who underwent abdominal rectal resection and stapled “high” coloanal anastomosis without a pouch, being the HCAA-P group; and 34 who underwent anoabdominal(More)
Farrar reported that in chronic anterior disk displacement without reduction (ADD w/o R) of the temporomandibular joint (TMJ), the range of mandibular movement gradually increases and the condylar movement normal-disk is still displaced anteriorty. The relationship between condylar rotation and translation was studied in opening/closing jaw movements before(More)
To the Editor: Drs. Naveau et al are to be congratulated for their excellent work in analyzing the outcome of a large series of patients treated with Nd-YAG laser therapy for palliation of esophageal and cardial cancer (1). They have undertaken a formidable analysis of their treated patients and conclude that laser therapy should be proposed as first-line(More)
We describe herein our technique of using an ultrasonically activated scalpel (Harmonic Scalpel [HS]) to simplify the procedure of anorectal mucosectomy for ulcerative colitis (UC). This technique was successfully employed to perform restorative proctocolectomy and ileoanal anastomosis (IAA) in ten patients with UC. By using the HS, thermal injury of the(More)
In this study, we evaluated the postoperative functional results after resection of rectal carcinoma. A questionnaire and anal manometry were used to evaluate the severity of the symptoms. The patients were divided into the three groups of anterior resection (AR, 38 patients), low anterior resection (LAR, 34 patients) and stapled colo-anal anastomosis (SCA,(More)
Colorectal cancer patients with central venous catheters (CVC) for pharmacokinetic modulating chemotherapy (PMC) have a substantial risk of venous thromboembolism (VTE). PMC, designed as a hybrid of lower metronomic and higher shorter plasma 5-FU concentrations, has been clinically successful. To determine the effectiveness and safety of D-dimer tests and(More)
Non-functional activities, such as bruxism, have been implicated in the development of temporomandibular disorders (TMD). It would be of value to have an animal model in which to investigate the processes underlying such disorders. The aim of this study was to determine the electromyographic (EMG) characteristics of experimentally induced, non-functional(More)
The incidence of postoperative hyperamylasaemia was evaluated in 70 patients who underwent staged restorative proctocolectomy. On the 14th postoperative day, 27 of 70 patients after total colectomy showed hyperamylasaemia, and the serum amylase returned to normal on the 30th postoperative day. Three out of 37 after ileoanal anastomosis and 8 out of 70 after(More)
