Impact of anatomical wrap position on the outcome of Nissen fundoplication.

BACKGROUND: The importance of anatomical reposition and fixation of the type I hiatal hernia during antireflux surgery has often been emphasized. It is not known whether the initial anatomical repair withstands the test of time and whether this repair is necessary for a successful outcome. METHODS: The relationship between the objective anatomical and subjective symptomatic outcome of Nissen fundoplication was investigated prospectively in 57 patients. Findings of herniation, telescoping and obstruction at the level of the lower oesophageal sphincter on barium swallow were scored 2 years after operation by investigators who were unaware of the symptoms, and were related to symptoms and patient satisfaction evaluated by a standard questionnaire. RESULTS: According to strict criteria, some 55 per cent of patients had some degree of anatomical failure; if only complete herniation, significant telescoping and signs of obstruction were scored as abnormal, 27 per cent had anatomical failure. There was no relation to subjective outcome; relief was reported by 48 of 49 patients, 25 of whom were cured and 23 significantly improved. CONCLUSION: Anatomical repair during antireflux surgery does not stand the test of time. Although this has no demonstrable influence on the subjective outcome, the authors do not recommend deviating from well designed surgical guidelines. Current theories on the mechanism of antireflux surgery require further evaluation.

Functional results and visceral perception after ileo neo-rectal anastomosis in patients: a pilot study.

INTRODUCTION: To reduce pouch related complications after restorative proctocolectomy, an alternative procedure was developed, the ileo neo-rectal anastomosis (INRA). This technique consists of rectal mucosa replacement by ileal mucosa and straight ileorectal anastomosis. Our study provides a detailed description of the functional results after INRA. PATIENTS AND METHODS: Eleven patients underwent an INRA procedure with a temporary ileostomy. Anorectal function tests were performed two months prior to and six and 12 months after closure of the ileostomy and comprised: anal manometry, ultrasound examination, rectal balloon distension, and transmucosal electrical nerve stimulation (TENS). Function was subsequently related to the histopathology of rectal biopsy samples. RESULTS: Median stool frequency decreased from 15/24 hours (10-25) to 6/24 hours (4-11) at one year. All patients reported full continence. Anal sensibility, and resting and squeeze pressures did not change after INRA. Rectal compliance decreased (2.1 (0.7-2.8) v 1.5 (0.4-2.2) and 1.4 (0.8-3.7) ml/mm Hg (p=0.03)) but the maximum tolerated volume increased (70 (50-118) v 96 (39-176) (NS) and 122 (56-185) ml (p=0.03)). Decreasing rectal sensitivity was found: the maximum tolerated pressure increased (14 (8-24) v 22 (8-34) (NS) and 26 (14-40) (p=0.02)) and the rectal threshold for TENS displayed a similar tendency. All patients displayed a low grade chronic inflammatory infiltrate in neorectal biopsy samples before closure of the ileostomy, with no change during follow up. CONCLUSIONS: The technique of INRA provides a safe alternative for restorative surgery. Stool frequency after INRA improves with time and seems to be related to decreasing sensitivity and not to histopathological changes in the neorectum. Furthermore, after the INRA procedure, all patients reported full continence.

[Treatment of severely delayed gastric emptying]. / Behandeling bij ernstig vertraagde maaglediging.

For the drug treatment of gastroparesis, domperidone, metoclopramide and cisapride may be prescribed as prokinetics. Positive effects on the rate of emptying of the stomach, dyspeptic symptoms and quality of life are best documented for cisapride. Simultaneous use of cisapride with substances that inhibit the metabolism of cisapride or that may lengthen the QT interval, is contraindicated because of the risk of arrhythmias. Erythromycin is a powerful prokinetic, but because of its antibiotic effects it is usually prescribed only for a brief period. For patients who in spite of drug treatment have persistent unacceptable symptoms and keep losing weight, invasive treatment should be considered. The first step is then insertion of a jejunal tube, followed, if necessary, by antrectomy with Billroth-I reconstruction. The next step is subtotal gastrectomy with Roux-Y reconstruction, this may result in abatement of the symptoms, which, however, rarely disappear altogether.

The relationship between carcinoma of the rectum and hemorrhoids.

The suspected positive correlation between rectal carcinoma and hemorrhoids was examined in a retrospective study. In patients older than 50 a significant positive correlation could be demonstrated between rectal carcinoma and hemorrhoids. In the group of hemorrhoid patients described it could not be shown that rectal carcinoma was more frequent than in the normal population. In patients older than 40 with hemorrhoids a rectoscopy is always recommended. In this material the colonic enema did not contribute any diagnostic information from which therapeutic consequences could be inferred.
