Long-term follow-up of patients with iron deficiency anemia after a close endoscopic examination of the upper and lower gastrointestinal tract.

2000

Background In patients with Iron Deficiency Anemia (IDA) occult gastrointestinal bleeding is generally investigated by bidirectional endoscopy. The aim of our study was to examine the long-term follow-up of patients with IDA where the sources of bleeding couldn't be detected despite close endoscopic and radiologic examination of the GI tract. Methods Based on the endoscopic data base we examined consecutive patients who were referred for gastrointestinal endoscopy due to IDA with a negative endoscopic (upper GI endoscopy and colonoscopy) evaluation. Further diagnostic work up (repeated endoscopy of the upper and lower GI tract by an experienced investigator, small bowel enteroclysis, push e…

Bacteremia after proctoscopy and hemorrhoidal injection sclerotherapy

1981

The incidence of bacteremia following proctoscopy and hemorrhoidal injection sclerotherapy was studied in 50 outpatients undergoing both procedures. Bacteremia was found in 2 per cent of the subjects after proctoscopy and in 8 per cent after sclerotherapy. None of the subjects developed symptoms of septicemia following the procedure. It is concluded that antibiotic prophylaxis should be used before sclerotherapy in patients with valvular heart disease or compromised host defense.

Severe acute colitis associated with CMV: a prevalence study.

2005

Abstract Background. Cytomegalovirus has been identified as a pathogen that contributes to flares of colitis when detected in colonic specimens of patients with inflammatory bowel disease. Aim. To determine the overall prevalence and the role of cytomegalovirus infection in a consecutive series of patients with acute severe colitis admitted to our department from 2000 to 2003. Methods. Among 42 patients (38 with ulcerative colitis and 4 with Crohn's disease) admitted to our hospital for acute severe colitis, we performed proctoscopy and biopsy together with blood sample for cytomegalovirus determination at the time of admission, regardless of their steroid resistance. Results. In the 42 pat…

Endoscopic laser palliation for rectal cancer-- therapeutic outcome and complications in eighty-three consecutive patients.

2002

OBJECTIVE The treatment of advanced rectal cancer is still a challenge. We analysed the short-term success, treatment-related complications and the long-term outcome after laser palliation for rectal cancer. METHODS Over a ten-years period eighty-three consecutive patients (median age 81 (46-94) yrs; 43 female) were treated mainly for obstructive symptoms or tumour bleeding. Laser palliation was performed using a Neodymium:Yttrium-Aluminium-Garnet (Nd:YAG) laser. RESULTS The immediate overall-success rate was 96.4 % (80 of 83 patients) and only one female received a diverting colostomy because of an inaccessible high-grade rectal stenosis, initially. During follow-up, eight additional patie…

Transanal endoscopic microsurgical excision of pT2 rectal cancer: results and possible indications.

2007

In previous studies, local excision was predominantly established for "low-risk" pT1 rectal cancer. The results obtained with T2 tumors are unclear; recurrence rates of 0 to 67 percent were reported. This study was designed to determine the value of local excision for T2 rectal carcinomas, prognostic factors, and the need for reoperation.After local excision of 649 patients with rectal tumors, pT2 carcinoma was found in 44 patients. In general, immediate reoperation was recommended; however, 24 patients declined further surgery or were not reoperated because of comorbidities. The results were analyzed separately for local R0 resection of low-risk carcinomas and for prognostically unfavorabl…

High frequency of colorectal adenoma in patients with duodenal adenoma but without familial adenomatous polyposis

2004

Abstract Background Duodenal adenomas are extremely common in patients with familial adenomatous polyposis. However, it is uncertain whether patients with duodenal adenomas without familial adenomatous polyposis are at greater risk for colorectal neoplasia and, therefore, should routinely undergo surveillance colonoscopy. The aim of this study was to determine whether there is a correlation between non-papillary duodenal adenoma without familial adenomatous polyposis and colorectal adenoma. Methods Twenty-five patients with non-papillary duodenal adenomas without familial adenomatous polyposis, seen from January 1990 to April 2003, were retrospectively evaluated. Results Non-papillary duode…

Training program for transanal endoscopic microsurgery.

1988

Televised endoscopy and the concept of the “assisted” endoscopic operation is of great help in teaching surgical endoscopic techniques. The use of training dummies provides a new method of training manual dexterity and surgical skills in special courses or in surgical skill laboratories. We have developed a training system for transanal endoscopic microsurgery. Operations with our technique were performed on 116 patients. Like other microsurgical techniques, our method requires a special introduction and intensive training. This paper presents our multistage, video-supported training course for teaching transanal endoscopic microsurgery. The one-day training session is divided into four ste…

Bericht zum 1. Workshop zur lokalen Exzision von Rektumkarzinomen

2007

To determine the significance of local excision (LE) of rectal cancer and discuss oncologic results, a 1st Workshop on LE of rectal cancer was held at the Department of General und Abdominal Surgery, Johannes Gutenberg-University Mainz, Germany. The option of broadening the indication for local excision after neoadjuvant radiochemotherapy (nRCT) of rectal cancer was to be assessed. Local excision of "low risk" T 1 carcinomas was rated as oncologically adequate therapy with good functional results and low complication rates. Transanal endoscopic microsurgical (TEM) resection was the preferrred technique. Pre-requisite for the achievement of low recurrence rates (5 %) is an R0 resection with …
