Quantitative and qualitative evaluation of phytoplankton communities by trichromatic chlorophyll fluorescence excitation with special focus on cyanobacteria.

We present results that were obtained with a newly developed fluorometer, the 'PhytoSensor'. They are based on multi-wavelength excitation of chlorophyll fluorescence to detect the phytoplankton biomass and to identify main taxons (among cyanobacteria, green and brown microalgae). A method to evaluate the photosynthetic potential of the phytoplankton was established. Attention was focused on the measurement of the cyanobacterial biomass. A modelling to distinguish between the two spectral groups (blue and red) of cyanobacteria as a function of their pigments and physiological status is proposed. The main innovation of the device results in the recording of the fluorescence induction kinetics of the phytoplankton to confirm and refine the evaluation of the taxonomic composition. The PhytoSensor abilities were compared with pigment analysis, commercial fluorometers, particle and microscopic counting and identification. The PhytoSensor has been used with success to monitor the dynamics of phytoplankton in drinking-water supply reservoirs in Southeast Asia.

Gastroduodenal tolerability of medium dose enteric-coated aspirin: a placebo controlled endoscopic study of a new enteric-coated formulation versus regular formulation in healthy volunteers.

We compared, in a cross-over study, the toxicity of 300 mg enteric-coated aspirin with regular aspirin used for the prevention of cardiovascular events. In terms of endoscopic haemorrhagic lesions, enteric-coated aspirin is less gastrotoxic than regular aspirin.

In-situ endothelial cell adhesion molecule expression in ulcerative colitis. E-selectin in-situ expression correlates with clinical, endoscopic and histological activity and outcome.

BACKGROUND AND OBJECTIVES: Little is known of the in-situ expression of adhesion molecules in ulcerative colitis (UC) according to disease activity. In the present study we investigate the vascular expression of endothelial leucocyte adhesion molecule 1 (ELAM-1/E-selectin), vascular cell adhesion molecule (VCAM-1) and intercellular adhesion molecules (ICAM-1 and ICAM-3) on the rectal mucosa of patients with UC in order to identify links between in-situ expression of these adhesion molecules and clinical, endoscopic and histological parameters. DESIGN AND METHODS: At inclusion, 16 untreated patients with UC at different stages of disease activity were assessed clinically and endoscopically and underwent rectal biopsy. Ten patients had similar assessments during follow-up. Quantitative histological and immunohistochemical scores were established with anti-E-selectin, VCAM-1, ICAM-1, ICAM-3 and HLA-DR monoclonal antibodies on frozen biopsy specimens. RESULTS: (1) At inclusion, E-selectin in-situ expression correlated with clinical activity (r = 0.7, P = 0.05), endoscopic severity (r = 0.74, P = 0.04), the histological score (r = 0.57, P = 0.02) and in-situ expression of HLA-DR on epithelial cells (r = 0.74, P = 0.01). (2) After remission, there was a significant decrease in ELAM-1 in-situ expression (P = 0.04). (3) In patients with clinical, endoscopic and histological remission the level of residual E-selectin expression appeared to be predictive of clinical relapse. (4) Vascular expression of VCAM-1 and ICAM-1 did not correlate with clinical, endoscopic or histological parameters, or with changes in disease activity. (5) ICAM-3 was never detected on endothelial cells of the colonic mucosa of controls or patients with UC. CONCLUSION: In ulcerative colitis, E-selectin, but not VCAM-1, ICAM-1 or ICAM-3, appears to play a central role in leucocyte migration into the colonic mucosa. Elevated vascular expression of E-selectin after remission may be involved in clinical recurrence.

Effect of pinaverium bromide on jejunal motility and colonic transit time in healthy humans.

Pinaverium bromide is a specific calcium channel blocker used in the treatment of irritable bowel syndrome (IBS) for its spasmolytic activity. The aim of the present study was to evaluate the effect of orally administered pinaverium bromide on jejunal motility and total and segmental colonic transit time in control subjects. Gastrointestinal studies were performed in 10 healthy volunteers (30 +/- 3 years), before and after a treatment phase of 14 days (150 mg/d). Jejunal motility was measured by prolonged manometry (14 h) and colonic transit time by a multiple ingestion, single marker technique. No significant modification of phase III of the migrating motor complexes was demonstrated. On the contrary, a significant (p < 0.01) but weak decrease of the frequency of contraction was found. Unlike previous studies, no decrease of total or segmental colonic transit time was demonstrated.

[Action of trimethyl 3,3-N-hexene-5-lactam on the mechanical properties of the longitudinal fibers of the rat colon. An in vitro study]. / Action du triméthyl-3,3-N-hexène-5-lactame (T.H.L.) sur les propriétés mécaniques des fibres longitudinales du colon de rat. Etude "in vitro".

The effects of trimethyl 3,3-N-hexene-5-lactam (T. H. L.) on the mechanical properties of longitudinal muscle strips of the distal rat colon were investigated through stretching, electrical stimulation and addition of pharmacologic agents. T. H. L. abolished the contraction induced by electrical stimulation and decreased amplitude of contractions induced by carbamoylcholine and serotonin. It further reduced the relaxation induced by adrenaline.

Methodological factors affecting esophageal clearance.

To define some methodological factors that could affect the measurement of the esophageal clearance, we used three different protocols, on 41 healthy control subjects. In 20 subjects, we studied the influence of a naso-esophageal probe on the frequency of swallowing. We observed a significant (44 +/- 5%) decrease in the frequency of spontaneous swallows after 15 minutes, with stabilization after this 15 minute period of adaptation. In 11 subjects, we studied the influence of the pH of the esophageal content on esophageal clearance. We found an exponential relationship between the esophageal clearance (C) expressed in minutes and the initial pH of the lumen contents: C = 43.3 exp (-0.54 pH) In 10 other subjects, we studied the influence of the volume of the esophageal contents on esophageal clearance. We found no influence for volumes less than 30 ml and a significant increase of clearance for volumes greater than 30 ml. In summary, this study of the effects of methodological factors on esophageal clearance: Gives new information about the "accommodation phase" of the esophagus after distension by a naso-gastric probe; Allows us to propose a new quantitative method for evaluation of esophageal clearance Shows the small importance of the ingested volume.

Relationship between acid neutralization capacity of saliva and gastro-oesophageal reflux.

Saliva is an important factor in neutralization of oesophageal acid exposure, clinically manifested as gastrooesophageal reflux (GOR). The aim of this study is to compare the composition and the "capacity in acid neutralization" (CAN) of saliva in controls and patients suffering of GOR. We compared the composition of saliva from 56 patients who had symptoms of GOR with that of saliva from 20 healthy control subjects. After a standardized 24-hour period of pH-monitoring, 39 patients had normal pH reflux scores (normal acid score: NAc-GOR) and 17 had abnormal pH reflux scores (pathological acid score: PAc-GOR). Then, following a 10-h fast, total saliva was collected during ten minutes in all patients and in the healthy control subjects. The composition of the saliva samples was analysed and the titration curve was determined on 200 microliters aliquots by successive addition of 5 microliters volumes of 0.1 N Hcl. The GOR patients had significantly lower salivary concentrations of Na+ and of both free and bound sialic acids and had higher salivary concentrations of inorganic phosphates than the controls. These disorders were more marked in PAc-GOR patients. Initial pH was 7.43 +/- 0.43 in controls, 7.35 +/- 0.45 in NAc-GOR patients, and 6.91 +/- 0.53 in PAc-GOR patients. In the beginning of the titration curve, PAc-GOR patients were significantly different from NAc-GOR patients and from controls. Saliva of both groups of patients presented significant differences in the acidic portion of the titrations curves, at high volumes of added HCl. These data show that the composition of saliva was modified in patients with GOR disease compared to that of normal subjects. A difference in titration curves was also observed with a higher acidic buffering capacity in these GOR patients. The modifications in saliva composition suggest a role for inorganic phosophates in the acid neutralization capacity observed in GOR, perhaps linked with a adaptation to chronic acid exposure.

[Comparison of the cost-efficacy ratio of omeprazole and ranitidine in the treatment of reflux esophagitis]. / Comparaison des rapports coût-efficacité du traitement de l'oesophagite par reflux par oméprazole et ranitidine.

OBJECTIVE: The objective of this study was to compare the cost of achieving a unit of clinical success for treatment of reflux oesophagitis with either ranitidine or omeprazole. METHODS: After randomisation 430 patients with reflux oesophagitis (grade 2 or 3) were assigned to receive omeprazole 20 mg or ranitidine 150 b.i.d. for 8 weeks. Patients were given diary cards to assess their symptoms every day, and record every two weeks a life satisfaction index. Patients were seen after 4 and 8 weeks for symptoms assessment and repeat endoscopy at 8 weeks. The perspective of the analysis was that of the payer. The costs of medical care were based in French drug costs currently advertised, payment for physician and actual mean payment for upper GI endoscopy. RESULTS: The healing rates at 8 weeks in the omeprazole group and the ranitidine group were 93 and 67.5% respectively. After 8 weeks of treatment, life satisfaction was good in 81 and 53.6% and the relief of pain was 86,6 and 69,5% respectively. For each effectiveness criteria, omeprazole was more cost effective than ranitidine: cost per healed patient (2,338 F vs 2,744 F), cost per asymptomatic patient (2,510 F vs 2,964 F), cost per patient with a good or very good life satisfaction index (2,687 F vs 3,456 F). This advantage remained independent of the oesophagitis initial severity. The sensitivity analysis showed that the results were unsensitive to the variations of the efficacy variables in their confidence interval. CONCLUSIONS: This cost-effectiveness analysis suggests that in the treatment of reflux oesophagitis, the strategy with the more effective treatment is more cost-effective.

[Ileocolic linitis in Crohn's disease]. / Linite iléo-colique au cours d'une maladie de Crohn.

Intestinal cancer is uncommon in Crohn's disease but the risk of developing such a tumor is increased. Linitis plastica of the small bowel or colon is very rare. We report a case of ileocolonic linitis plastica which occurred 21 years after an ileocecal resection for Crohn's disease. Partial small bowel obstruction in relation with stricture of the preanastomotic loop prompted us to suspect disease recurrence. The tumor was not diagnosed either on preoperative work-up, or during surgery but only on the histological examination of the resected specimen. Palliative chemotherapy with 5 FU and folinic acid was performed. The patient was asymptomatic after a 17-month follow-up. This observation focuses on the clinical signs and course of linitis plastica. It also illustrates the difficulty of tumor diagnosis in Crohn's disease. Malignant transformation must be suspected if signs of active disease re-occur after a lengthy quiescent period.

[Acute pancreatitis revealing cystic fibrosis in an adult]. / Pancréatite aiguë révélatrice de mucoviscidose chez une adulte.

We report a case of pancreatitis as the first symptom of cystic fibrosis in a 22-year-old woman. The diagnosis was suspected upon the history of nasal polyposis and severe episodes of respiratory infections in infancy. The diagnosis was confirmed by sweat test. Genotyping showed a compound heterozygosity for mutations delta F508 and 5T. Acute pancreatitis is a rare manifestation of cystic fibrosis and an exceptional mode of initial presentation of the disease. It occurs in pancreatic sufficient patients, especially in young adults. This exceptional case shows that cystic fibrosis should be suspected in each case of idiopathic pancreatitis. Indications of cholecystectomy in patients with associated gallbladder lithiasis is discussed.

[Dieulafoy colonic ulcer. A rare cause of lower gastrointestinal hemorrhage]. / Ulcère de Dieulafoy colique. Une cause rare d'hémorragie digestive basse.

Dieulafoy's disease is an unusual cause of gastrointestinal hemorrhage, reported to account for less than 2% of acute gastrointestinal bleeding episodes. Bleeding occurs from a defect in an unusually large submucosal artery, through a minute mucosal erosion. Endoscopic diagnosis is sometimes difficult, but primary endoscopic therapy may be successful and should be attempted. In most cases the lesion is found in the proximal stomach. Sixteen cases of Dieulafoy's lesion located in the colon have been reported in the literature but only nine have been confirmed by histology. We present the case of a 63 year-old male with Dieulafoy's lesion of the transverse colon which was diagnosed by endoscopy and confirmed by histology.

[Severe hemorrhagic gastritis of radiation origin]. / Gastrite hémorragique sévère d'origine radique.

Severe gastric complications due to radiotherapy are uncommon, in particular hemorrhagic gastritis. A high total dose and, above all, high daily fraction appear to be the main risk factors in gastric injuries. A case of hemorrhagic gastritis induced by radiotherapy requesting a total gastrectomy is reported. The patient was treated for a primary gastric non-Hodgkin's lymphoma. Hemorrhagic gastritis occurred despite a low total dose (40 Gy) and 2 Gy daily fractions. Upper gastrointestinal endoscopy and repeated biopsies are usually insufficient to exclude a tumor recurrence. Endoscopic ultrasonography may argue for a recurrence or for radiation lesions. As the conservative treatment is usually ineffective, these gastrointestinal radiation injuries ought to be treated surgically. Besides it allows to ascertain the benign nature of radiation lesions.

[Comparison of push-type endoscopy and barium transit study of the small intestine in digestive bleeding and unexplained iron-deficiency anemia]. / Comparaison de l'entéroscopie poussée et du transit baryté de l'intestin grêle dans les saignements digestifs et les anémies ferriprives inexpliqués.

OBJECTIVES: A radiological examination of the small bowel is often performed in case of gastrointestinal bleeding of obscure origin. More recently, push-type enteroscopy has been reported as a valuable tool in this indication. The purpose of this study was to compare the diagnosis efficiency of these two procedures. METHODS: From February 1994 to February 1996, 40 patients (mean age: 52 years) with obscure gastrointestinal bleeding (iron-deficiency anemia without obvious cause of blood loss or malabsorption: n = 17; macroscopic gastrointestinal bleeding: n = 23) were examined by small bowel follow-through and push-type enteroscopy (jejunoscopy n = 19; double way examination n = 21). Each patient had negative upper and lower gastrointestinal tract endoscopies prior to small bowel examinations. RESULTS: Small bowel follow-through revealed only one lesion potentially responsible for blood loss (2.5%), corresponding to a jejunal leiomyoma. Push-type enteroscopy detected small bowel lesions potentially responsible for blood loss in 6 patients (15%). The lesions were located in the jejunum in 5 cases (arteriovenous malformations: n = 3; metastasis: n = 1; leiomyoma: n = 1), in the ileum in 1 case (leiomyoma). The efficiency of push-type enteroscopy for the detection of a small bowel lesion was of 22% in case of macroscopic bleeding and of 6% in case of iron-deficiency anemia. Push-type enteroscopy also revealed lesions previously undetected by gastroscopy or colonoscopy in 8 patients (20%). CONCLUSION: Push-type enteroscopy was more effective than small bowel follow-through to detect the origin of obscure gastrointestinal bleeding. Push-type enteroscopy revealed a cause of bleeding in 35% of patients, located in the small bowel in only 15% of the patients.

Mycobacterium paratuberculosis and Mycobacterium avium subsp. silvaticum DNA cannot be detected by PCR in Crohn's disease tissue.

BACKGROUND: The etiology of Crohn's disease remains unknown. A putative mycobacterial cause of the disease is still controversial. AIMS: To assess the mycobacterial hypothesis in Crohn's disease using a polymerase chain reaction technique. PATIENTS AND METHODS: Nested polymerase chain reaction with primers on the 16S-rRNA coding region (16S-rDNA) and with primers specific both to the insertion sequences (IS) 900, and IS 901/902 were used to amplify Mycobacterium paratuberculosis or Mycobacterium avium subsp. silvaticum DNA in frozen endoscopic intestinal biopsies or surgical resection specimens from patients with Crohn's disease (n = 47: 25 endoscopic biopsies and 22 surgical resection samples, +/- lymph nodes), ulcerative colitis (n = 27), and non inflammatory bowel diseases (n = 20: colonic tumors and diverticulitis). Positive as well as negative controls were used throughout the study. RESULTS: All strains of Mycobacterium paratuberculosis and Mycobacterium avium subsp. silvaticum tested were positive for both primer systems. Of the 94 biopsies tested, 5 (2 Crohn's disease, 1 ulcerative colitis and 2 controls) were positive with the 16S-rDNA primers but did not correspond to Mycobacterium paratuberculosis or Mycobacterium avium subsp. silvaticum. None of the specimens was positive with the IS primers. CONCLUSION: These results do not support the hypothesis that Mycobacterium paratuberculosis, or Mycobacterium avium subsp. silvaticum play a role in Crohn's disease.

[Evaluation of the gastrotoxicity of anti-inflammatory drugs: contribution of general registries of digestive endoscopy]. / Evaluation de la gastrotoxicité des anti-inflammatoires: apport des registres généraux d'endoscopie digestive.

The evaluation of the rate of gastroduodenal toxicity of anti inflammatory drugs is a difficult problem. We tried to analyse that question by studying the general endoscopic registers of the Gastro-Enterologic department of the hospital. This retrospective study concerns 2,945 endoscopies performed during the year 1988 and 1992 randomly chosen among the last 5 years. 992 results show injuries suggestive of non steroidal anti inflammatory drugs (NSAID) toxicity, however only in 65 cases the potential role of an anti inflammatory drug is mentioned: 36 men and 29 women, mean age: 50.6 +/- 19.6 years. Concerning the drugs, only the pharmacological classes they belong to are mentioned except for Aspirin. Acetyl salicylate acid 7 cases, NSAIDS 36 and Steroids 22. In the drug group 63% of injuries are located to the stomach (ulcers 13%, gastritis 50%), 37% to the duodenum (19% ulcers, 18% duodenitis). Compared to the groups with the same kind of injuries, but without any mention of drugs, there are no statistical difference in the proportion of ulcers. Aging and sex are not influent in our results on the genesis of drug induced ulcers. These results must be discussed because a lot of datas are missing in the registers and so the number of patients taking drugs is probably underestimated. This means that unless a prospective study is held with someone enquiring for all the risk factors, the study of the general endoscopic registers is not a good way to estimate gastrointestinal damages due to drugs.

[Cyclospora cayetanensis presence in aquatic surroundings in Hanoi (Vietnam). Environmental study (well water, lakes and rivers)]. / Cyclospora cayetanensis et sa présence en milieu hydrique à Hanoï (Vietnam). Etude dans l'environnement (eaux de forage, lacs et rivières).

Cyclospora cayetanensis is a pathogenic agent originating from the intertropical zone. It causes diarrhoeal diseases in local populations as well as in travellers visiting these zones. In the first part of this work, an epidemiological study on drinking water supply (reservoirs and consumers' taps) was conducted in Hanoi over 12 months; samples were daily collected and have revealed the presence of Cyclospora cayetanensis oocysts during the whole year in tanks and only during monsoon season. Molecular methods were used for species identification. In the second part, we tried to investigate different water sources in Hanoi city in order to detect Cyclospora cayetanensis environmental contamination: groundwaters, surface waters collected in lakes and rivers and also waters from treatment plants. Our results show that none Cyclospora cayetanensis oocyst was found in the groundwaters and in the desinfected finished waters after treatment. In contrast, in rivers and lakes samples, the level of positivity reached about 63.6% with significant differences between the districts regarding the rates of oocysts recovery: only 24% positive specimens in Hoan Kiem district, whilst respectively 80.4%, 78.3% and 65% positive samples in Hai Ba Trung, Dong Da and Ba Dinh districts. The results of this study seem to confirm that environmental water is contaminated by Cyclospora cayetanensis oocysts and points out the importance of water as a significant source of human transmission. It is quite obvious that observation could be probably extended to the other endemic areas.

[Selective segmental colectomy in diverticular sigmoiditis. The surgical risk is not increased after 70 years of age]. / Colectomie segmentaire à froid pour sigmoïdite diverticulaire. Le risque opératoire n'est pas majoré après 70 ans.

UNLABELLED: Segmental colectomy for complicated diverticulitis is often indicated, between attacks, in elderly patients. We report a retrospective study of operated patients over the age of 70. The aim of this retrospective study was to evaluate the age risk of consecutive patients operated between diverticular attacks by segmental colectomy, and whether such a surgical procedure is justified, as the life expectancy of these patients was 74 years for men and 81.9 years for women in 1996. PATIENTS AND METHOD: From January 1990 to December 1996, 117 patients were operated, between attacks, for complicated sigmoid diverticulitis; 31% (n = 37) were over the age of 70 years. They were 16 men and 21 women with an overall mean age of 77 (range: 70-85 years). Indications for surgery were repeated attacks (n = 17), large bowel stenosis (n = 14) and colovesical fistula (n = 6). The operation was performed an average 8 weeks after the last infectious episode (3-10 weeks). RESULTS: Among patients over the age of 70 years, the postoperative morbidity rate was 40% and there was no mortality. One patient was reoperated for an anastomotic abscess and was managed by protective colostomy and pelvic drainage with conservation of the anastomosis. CONCLUSION: This retrospective study shows that in our experience, one third of patients operated for a complication of diverticulitis were over the age of 70 years. In this subgroup, left colectomy, when performed between attacks carries an acceptable specific morbidity and no mortality. A further study could compare the percentage and outcome of operated patients with those who were denied surgery.

[Intraductal papillary mucinous tumors of the pancreas: are there any preoperative clinical and laboratory factors predictive of degeneration. Results of a French-Belgium collective series]. / Tumeurs intracanalaires papillaires mucineuses du pancréas: existe-t-il des facteurs pré-opératoires cliniques et biologiques prédictifs de dégénérescence? Résultats d'une série collective franco-belge.

Intraductal papillary and mucinous tumors are rare. We retrospectively analysed clinical, surgical and histological features and outcome of 41 operated patients (29 males, 12 females, mean age = 63 years). The commonest presenting manifestation was acute pancreatitis (41%). Tumor was located in only one pancreatic segment in 45% cases. Forty one per cent of patients had invasive carcinoma, 20% had tumor with severe dysplasia and 39% with minimal or moderate dysplasia. Only elevated age was significantly associated with invasive carcinoma. Eleven out of 17 patients with invasive carcinoma (65%) had a recurrence after surgery and 6 (35%) died. Among 24 patients with noninvasive tumor, 2 (8%) recurred without tumor-related death in the follow-up (48 months). This study underlines the need for early surgical resection in patients with intraductal papillary and mucinous tumor because of the high frequency of invasive carcinoma and the poor outcome of patients with invasive carcinoma.

[Prognostic factors of the speed of cicatrization in duodenal ulcer. Controlled trial of omeprazole versus ranitidine]. / Facteurs pronostiques de la rapidité de cicatrisation de l'ulcère duodénal. Essai contrôlé oméprazole vesus ranitidine.

OBJECTIVES: The treatment of duodenal ulcers has changed greatly since the introduction of anti-H2 drugs and sodium pump inhibitors. However the effect of several factors influencing prognosis and the rate of healing remain to be elucidated. METHODS: Five hundred forty five patients with a fibroscopically proven duodenal ulcer were included in a randomized controlled trial and were treated for one month with omeprazole (20 mg) or ranitidine (300 mg). Twenty epidemiological, clinical and fibroscopic factors of prognosis were recorded when the patients entered in the study and were analyzed after the treatment period. RESULTS: Endoscopic healing was obtained in 90% of the omeprazole treated patients and in 78% of the ranitidine group (p < 0.001). Multifactorial analysis of the 20 prognostic factors showed that, excepting the treatment factor, only the size of the ulcer (less than 11 mm), its shape (round), its localisation (not on the posterior side) and a moderate pain were factors of good prognosis. Paradoxically, in our study, male patients and alcohol consumption were also positive factors of prognosis. CONCLUSION: The probability of healing is best for round, small duodenal ulcers located on the anterior side of the bulb.

[Percutaneous endoscopic gastrostomy. Indications and results in 31 patients]. / Gastrostomie percutanée endoscopique. Indications et résultats chez 31 patients.

Nutritional assistance was indicated in 31 patients with an ENT tumour at different stages of treatment and different stages of the disease. These patients presented with disorders of deglutition with false passages (68%), aspiration pneumonia (10%), dysphagia (35%) or denutrition (17%). We used an endoscopic percutaneous gastrotomy kit produced by the Bioser company (pull technique). In 29 patients, the tube was inserted under general anaesthesia in the operating theatre to prevent dyspnoea during introduction of the tube in these patients with alteration of the airway-gastrointestinal tract junction or because the tube was inserted at the beginning of anaesthesia for ENT surgery. The tube was able to be inserted in every case, with cardiac arrest in one patient who was effectively resuscitated without sequelae, two obstructions of the cuff requiring advancement of the tube with a bougie, 2 ruptures of the thread and one case of dyspnoea. Two patients subsequently developed a wound abscess which was drained and one patient required removal of the tube. Follow-up of the patients demonstrated the good tolerance of this tube which was maintained for an average of 2.9 +/- 0.5 months (0.1 to 9 months) without any major complications. 3 benign wound infections, 4 inflammatory reactions, 4 minimal leaks, 1 case of hyperthermia, 12 cases of abdominal distension and 2 cases of displacement of the tube were observed. The weight gain was equal to 4%. The authors believe that this technique of endoscopic gastrostomy should be preferred to surgical gastrostomy.
