[Complexity index and analysis of digestive endoscopies at a university hospital].

BACKGROUND: In Spain neither the cost of digestive endoscopies nor the complexity index (CI) have been objectively estimated. Consequently, the profitability of an endoscopy unit cannot be evaluated. OBJECTIVES: 1: To classify endoscopies according to the time taken to accomplish them in order to estimate the CI and determine the relative value unit (RVU). 2: To evaluate the cost of each examination in order to determine the profitability of endoscopy as a diagnostic and therapeutic tool. 3: To measure unnecessary delays in examinations and to determine whether there are differences in the time an examination takes according to the endoscopist's experience and the patient's age or sex. MATERIAL AND METHODS: The cost per hour of an endoscopy room was estimated by dividing the cost per year of employees, equipment, maintenance and the hospital's general costs between the hours of work per year of the endoscopy team. The time taken to perform endoscopies was estimated and the result was used to calculate the RVI, the CI and the cost of 500 consecutive endoscopies. RESULTS: The annual cost amounted to 349,617.69 E. Staffing costs represented 65.5%, of which 56.3% were direct costs. Gastroscopy was taken as the RVU (cost = 27.52 E). Anoscopy was the simplest procedure (RVU = 0.61, cost = 15.08 E) and colonoscopy plus polypectomy was the most complex procedure (RVU = 4.41, cost = 74.28 E). The greater the experience of the member of staff performing the procedure, the less time it took (p < 0.01). CONCLUSION: CI was lowest for anoscopy (URV = 0.61) and highest for total colonoscopy plus polypectomy (URV = 4.41). Cost and exploration time depended on the endoscopist's experience. Staff represented the highest percentage of cost.

Association of MALTectomy (appendectomy and tonsillectomy) and inflammatory bowel disease: a familial case-control study.

UNLABELLED: There is some controversy regarding the prevalence of tonsillectomy and appendectomy among patients with Crohn's disease (CD) and a lower rate of appendectomy among patients with ulcerative colitis (UC). However, some environmental and familial factors that could alter those figures have not been studied. OBJECTIVE: To explore the prevalence of MALTectomy (appendectomy and tonsillectomy) among patients with IBD, stressing those factors that may be significantly associated to it. METHOD: Age-and-sex matched case-control study in patients with IBD, their relatives and the general population. Two hundred and eighty seven cases were IBD patients (153 UC, and 134 CD), the "family control" group included 203 siblings and the population-based control group included 570 individuals. Potential confounding factors, such as smoking, educational level, oral contraceptive use, place of birth and residence up to the age of 15 years, were ruled out. RESULTS: Appendectomy and UC: 7% of UC patients had undergone appendectomy versus 20% (OR: 0.23; 95% CI: 0.11-0.5; p < 0.0001) of controls. Appendectomy rates in families with at least one case of UC were 17/153 (6.3%) and 61/306 (20%) in the control group (p < 0.001). Appendectomy and CD: Twelve per cent of CD patients had undergone appendectomy six months before the onset of the disease versus 17% among the control population (OR: 0.43; 95% CI: 0.29-0.95; p < 0.01). The frequency of appendectomy in families with at least one case of CD was 22/221 (10%), which was significantly lower (p < 0.05) than among the control group 45/264 (17%). No differences were found between IBD patients and familial controls. Tonsillectomy and CD: Forty six per cent of CD patients had undergone tonsillectomy versus 39% of control patients (OR: 1.77; 95% CI: 0.92-2.05; p = ns). Tonsillectomy and UC: Twenty eight per cent of UC patients had undergone tonsillectomy versus 39% of the population control group (OR: 1.07; 95 CI: 0.57-1.25: p = ns). In fact, no differences were found regarding the prevalence of tonsillectomies within families with IBD cases as compared to population controls. CONCLUSIONS: Appendectomy is not only less frequent among CD and UC patients, but also among their relatives, thus suggesting the existence of environmental and genetic factors with opposed etiological roles in IBD and appendicitis.

High-dose intravenous cyclosporine in steroid refractory attacks of inflammatory bowel disease.

BACKGROUND/AIMS: To determin whether cyclosporine is effective in inducing remission in patients with severe active inflammatory bowel disease, refractory to steroids. METHODOLOGY: Twenty-three patients with severe and steroid-refractory inflammatory bowel disease (15 ulcerative colitis and 8 Crohn's disease) were included. The Mayo Clinic Score and the CDAI were used to evaluate activity. Cyclosporine (4 mg/kg/day) was administered for a maximum of ten and a minimum of 7 days. RESULTS: Ten of the 15 ulcerative colitis patients achieved remission with a mean response lag time to onset improvement of 8 days. Seven of these patients remained stable with mesalazine 4 months after cyclosporine treatment. Two patients relapsed and underwent colectomy on the 50th and 200th day after treatment. Five patients presented no response and required urgent colectomy. Six of the 8 Crohn's disease patients achieved remission with a mean response lag time to onset improvement of 7 days. The 6 patients remained stable with mesalazine four months after cyclosporine treatment. The other 2 developed reversible renal failure and had to be released from the study. CONCLUSIONS: Intravenous high dose cyclosporine is effective and can be used as a rapid onset treatment for acute steroid refractory IBD.

[Mallory-Weiss syndrome. Considerations on 27 cases].

Twenty seven patients, inspected by endoscope, and diagnosed as having the Mallory-Weiss syndrome, have been studied taking into account their age, sex, background, clinic presentation, manifestations, number of lacerations, associated lesions and evolution. Twenty three of them were males and 4 females. The age average was 46.7 years. Only 8 patients had intra-abdominal increased pressure, suffering retching and vomiting 7 of them, while one had a cough access. Out of the 21 patients that we controlled, 9 were chronic alcoholism while 3 had ethanol intoxication previously. Immediate prior ingestion of salicylates had taken place in 6 patients. The clinical presentation of 22 of them was gastrointestinal bleeding, that is, 4.9% of all the upper endoscopies carried out within the bleeding patients. Single laceration was present in 22 cases, double one in 4, and triple in 1. We have frequently found endoscopy lesions associated, the most common one (37%), was hiatal hernia. They all were medically treated except one, who was operated because of gastric perforation was associated. Just one of the Mallory-Weiss syndrome patient died, due to an associated diffused bleeding gastritis.
