Experience with enteral nutrition in a hospital population of acutely ill patients.

Enteral feeding has unique metabolic and immune advantages. This article describes the successful use of enteral nutrition, alone or in combination with parenteral feeding, in a tertiary-care hospital. Study participants were 89 patients who received enteral feeding during a 6-month period. These critically ill patients (ranging in age from 55 to 71 years) had severity of illness levels of 7 to 25 according to the Acute Physiologic and Chronic Health Evaluation (APACHE II) system and lengths of hospital stay from 27 to 73 days. Mortality was as high as 50% in patients with liver disease (nonmalignant), 35% in patients with cardiothoracic and vascular diseases, and 17% in patients with cancer and other diseases. Despite the severity of illness, patients met their energy and protein intake goals through enteral or combined feeding with total parenteral nutrition. Serial weights (ie, obtained weekly) and serum albumin concentrations did not improve during hospitalization. Complications related to enteral feeding were minimal (< 17% incidence). Differences were noted between survivors and nonsurvivors: nonsurvivors had lower serum albumin concentrations at the time of admission, had longer hospitalizations, and required total parenteral nutrition for more days than the survivors. Nonetheless, even with extremely sick patients, provision of enteral nutrition can be successful using the administration techniques we describe. Enteral nutrition could best be provided by beginning at a slow rate (10 c3/hour), inserting the feeding tube past the pylorus, and feeding according to sensible energy goals (25 kcal/kg of body weight), and using elemental then polymeric formulas.

Randomised clinical trial investigating the effects of combined administration of octreotide and methylglucamine diatrizoate in the older persons with adhesive small bowel obstruction.

OBJECTIVE: To investigate the effects of combined administration of octreotide and methylglucamine diatrizoate in the older persons with adhesive small bowel obstruction. PATIENTS AND METHODS: One hundred and sixty-two consecutive patients who had suffered from adhesive intestinal obstruction without clinical evidence of strangulation or gangrene were randomised into two groups, a control group (treated conservatively, n=82) and a contrast group (treated with combined administration of octreotide and methylglucamine diatrizoate, n=80). A laparotomy was performed in both the two groups if symptoms of strangulation developed or the obstruction did not resolve spontaneously after 72 h. RESULTS: Statistically significant rapid reduction in pain score, lower amount of nasogastric drainage, shorter hospital stay, lower operative rate and lower postoperative morbidity were observed in the contrast group. Among the non-operative patients, earlier passage of stool and gas, earlier first oral intake and shorter duration of nasogastric tube placement were significantly more frequently observed in the contrast group. No difference in the rate of readmission was found between the two groups. CONCLUSIONS: Combined administration of octreotide and methylglucamine diatrizoate accelerates resolution of small bowel obstruction by a specific therapeutic effect and is safe for the older persons.

Non-surgical management of microperforation induced by EMR of the stomach.

BACKGROUND: Perforation and bleeding are major complications associated with gastric endoscopic mucosal resection. Evident perforation during endoscopic mucosal resection can be managed by endoscopic clipping. However, management of microperforation is not well established. PATIENT AND METHOD: From January 2002 to June 2004, 109 early gastric cancers and 300 adenomas were treated with endoscopic mucosal resection. Iatrogenic perforations occurred in 4.16% (n=17) patients. Following exclusion of four evident perforations, microperforation was observed in 3.18% (n=13) patients. The clinical features of microperforation in patients were retrospectively reviewed. RESULTS: In a total of 13 microperforation cases, 2 patients were managed surgically. The remaining patients successfully recovered without surgical management. In the case of 11 patients without surgery, 7 experienced abdominal pain, which required analgesics, 2 patients experienced mild discomfort and 2 patients experienced no symptoms. A body temperature above 37.5 degrees C was observed in 9.1% (n=1) patients and leucocytosis above 9000 microL-1 was in 72.7% (n=8) patients. The mean duration of nasogastric tube drainage was 2.36+/-1.03 days, of fasting 4.18+/-1.17 days, of intravenous antibiotics 5.55+/-1.44 days and of hospitalisation 7.45+/-1.04 days. CONCLUSION: Microperforation induced by gastric endoscopic mucosal resection can be managed successfully using a non-surgical approach including fasting, nasogastric tube drainage and intravenous antibiotics.

Specific oral medications decrease the need for surgery in adhesive partial small-bowel obstruction.

BACKGROUND: Nothing by mouth (NPO) is the standard treatment for small-bowel obstruction. Whether oral medications should be prohibited during treatment of adhesive, partial small-bowel obstruction is unclear. The goal of this study was to determine whether a combination of specific oral medications in adhesive, partial small-bowel obstruction will decrease the need for operative intervention. METHODS: Of 266 consecutive adult patients with partial small-bowel obstruction admitted at a tertiary medical center, 236 were randomized into 2 groups. Group I patients were treated with intravenous hydration, nasogastric tube decompression, and NPO. Group II patients were placed on intravenous hydration, nasogastric tube decompression, and oral fluids incorporating an oral laxative, a digestant, and a defoaming agent. We compared differences between the groups in (1) the number of patients having a successful nonoperative treatment, (2) complications, and (3) recurrence of symptoms. RESULTS: A total of 116 and 120 patients comprised groups I and II, respectively. The number of patients treated successfully by a nonoperative approach was less in group I than in group II (77% vs 90%, P < .01). The complications and recurrence rate for groups I and II did not differ (4% vs 5% and 5% vs 4%, respectively). CONCLUSIONS: The NPO status for patients with adhesive, partial small-bowel obstruction may not be necessary. This cocktail of oral medications can decrease the need for operative intervention in patients with presumed adhesive, partial small-bowel obstruction.

Long tube decompression is successful in 90% of patients with adhesive small bowel obstruction.

BACKGROUND: For patients with small bowel obstruction (SBO), who do not have strangulation obstruction or other contraindications, long tube decompression has been successful in 75% in two studies. In a 1995 prospective randomized study, comparing nasogastric suction (short tube) with long tube decompression, the short tube was successful in 51% and the long tube was successful in 75%. Using upper gastrointestinal endoscopy, a long tube can be advanced into the jejunum in 20 minutes, so the delay in function has been eliminated. METHODS: There were 35 patients with 37 episodes of SBO. From 1983 to 1988, three tubes then available were advanced endoscopically into the jejunum in 17 patients. From 1989 to 2002, an improved tube designed for endoscopic placement was used in 20 patients. RESULTS: From 1983 to 1988 using three tubes, long tube decompression was successful in 12 of 17 (70%); from 1989 to 2002 with the improved tube, decompression was successful in 18 of 20 (90%). CONCLUSIONS: For patients with SBO due to adhesions, a trial with long tube decompression for 48 to 72 hours is recommended. For those who fail a trial with the long tube, laparotomy with enterolysis or bowel resection is indicated. If the operative findings indicate a high risk for recurrent obstruction, then long tube splinting of the small bowel should be considered.

Ultrathin endoscopy in the assessment and treatment of upper and lower gastrointestinal tract strictures.

BACKGROUND: Ultrathin (</= 6 mm diameter) endoscopes have recently been introduced into clinical practice. METHODS: We retrospectively assessed the role of a 6 mm diameter videoendoscope in 15 patients with tight gastrointestinal tract strictures. RESULTS: The ultrathin endoscope was successfully passed through 9 of 12 esophageal strictures not amenable to endoscopy with a standard-diameter endoscope allowing stricture dilatation or nasogastric tube placement in 8 of these. Ultrathin endoscopy was also successful in passing 3 lower gastrointestinal tract strictures caused by Crohn's disease that were impassable using larger-diameter endoscopes. CONCLUSION: Ultrathin endoscopy is potentially useful in the assessment and treatment of some upper and lower gastrointestinal tract strictures.

Thal fundoplication in neurologically impaired children.

Children with neurological impairment (NI) frequently require feeding gastrostomy, and this often aggravates or produces gastroesophageal reflux (GER). From 1976 to 1994, 141 children with severe NI underwent Thal fundoplication and gastrostomy (GT). GER was evident in 80%; in the rest, fundoplication was an adjunct to GT. Ph results were positive in 38 cases, and 57 children had reflux according to the barium studies. There were no major intraoperative complications. Disruption of the repair and/or recurrent GER was noted in 14 cases (10%); 8 were redone as Thals, and 6 were converted to Nissen procedures. Pyloroplasty was done later in 9 children (6%). Bowel obstruction was seen in 4 patients (3%). Clinical follow-up (mean, 54 months) showed improvement in 96%; only 5 of the 141 (3.2%) have residual symptoms. Of the patients with an intact Thal, 67% could burp or vomit. The ability to vomit may protect the Thal fundoplication and avoid disruption of the repair.

Bedside placement of nasojejunal tubes: a randomised-controlled trial of spiral- vs straight-ended tubes.

BACKGROUND AND AIMS: The success rate of unguided nasojejunal feeding tube insertion is low, thus often requiring endoscopic or radiological assistance. The spiral end of the Bengmark nasojejunal tube is supposed to aid post-pyloric placement, but no comparative trial has been performed. METHODS: Patients requiring nasojejunal feeding were randomised to have either Medicina (straight) or Bengmark (spiral) nasojejunal tube placed after stratification into those with normal gastric emptying or clinical evidence of delayed gastric emptying. Nasojejunal tubes were placed at the bedside in a standard fashion without radiological guidance by the same person for pre- and/or post-operative feeding. Bolus intravenous metaclopromide (10mg) was given prior to insertion in the abnormal gastric emptying group. Abdominal radiographs were obtained at 4 and 24h, and the primary end-point was jejunal placement at 24h. RESULTS: Forty-seven patients were randomised of which 17 (11 straight, 6 spiral) could not tolerate the nasojejunal tube. Of the 30 remaining patients, 16 had normal gastric emptying. In patients with normal gastric emptying, successful placement at 24h was achieved in 78% (spiral tube), vs 14% (straight tube) (P=0.041). In the abnormal gastric emptying group, success rates were 57% and 0%, respectively (P=0.07). CONCLUSION: Spiral nasojejunal tubes are preferable to straight tubes for bedside unguided post-pyloric feeding in patients with normal gastric emptying.

Standardized perioperative care protocols and reduced length of stay after colon surgery.

BACKGROUND: Recent studies have suggested that critical pathways and standard order sets decrease hospital length of stay and improve quality of care. A recently conducted prospective, randomized study at our institution found that patients undergoing elective colon resections had earlier return of bowel function if perioperative epidural anesthesia and analgesia were provided. All patients in the study were also placed on a standardized perioperative regimen. We hypothesized that the standardized perioperative protocol used in this study contributed to early return of bowel function and hospital discharge compared with similar patients managed off protocol. STUDY DESIGN: To test this hypothesis, we performed a case-controlled study comparing the hospital courses of 36 study patients to 36 control patients undergoing colorectal surgery by the same surgeons during the same calendar year. The distribution of types of operations and anesthetic techniques was similar in both groups. RESULTS: As dictated by the protocol, all study patients had their nasogastric tubes removed, were started on a low fat liquid diet, and ambulated in the first postoperative day. Nasogastric tubes were removed in control patients and study patients 2.2 +/- 0.9 (mean value +/- SD) and 1.0 +/- 0.0 days postoperatively, respectively. Control patients were started on an oral diet, usually clear liquids, an average of 2.9 +/- 1.1 days postoperatively, a specific liquid diet was started 1.0 day postoperatively in study patients (p < 0.001). Return of bowel function, as determined by bowel tones, flatus, and bowel movements, occurred approximately 1 day earlier in study patients. Study patients were discharged 1 day sooner than control patients. CONCLUSIONS: Our results suggest that the return of bowel function and the length of stay of patients undergoing colon surgery are improved if patients are entered into a standardized protocol that eliminates variation in intraoperative and postoperative anesthesia and postoperative surgical care. We believe these results can be reproduced in routine clinical surgery by having a clearly outlined protocol for perioperative care similar to that used in this study.

A comparison of the effects of ranitidine and omeprazole on volume and pH of gastric contents in elective surgical patients.

BACKGROUND AND OBJECTIVE: In cases of aspiration of gastric contents the risk of pneumonitis is dependent on the pH and volume of the gastric contents. Omeprazole and rantidine each decrease gastric volume and increase gastric pH. We evaluated the efficacy of preoperative administration of omeprazole (60 mg) or ranitidine (150 mg) in the prophylaxis of aspiration pneumonitis. METHODS: Data were obtained from 75 elective female surgical patients randomly allocated to one of three groups, who received either omeprazole 60 mg orally, or ranitidine 150 mg orally, or neither, on the evening prior to, and on the morning of, surgery. Gastric volume and pH was measured using blind aspiration. RESULTS: Both pH < 2.5 and volume > 25 mL were present in none of the patients in either the ranitidine or omeprazole groups, compared to 15 of 25 control patients (P < 0.0001). CONCLUSIONS: Preoperative oral administration of omeprazole (60 mg) or ranitidine (150 mg) reduced residual gastric content volume and increased pH > 2.5, possibly reducing the effects of pulmonary aspiration of gastric contents.

Nitric oxide prevents rat duodenal contractions induced by potentially noxious agents.

After abdominal surgery, luminal HCl fails to induce duodenal contractions in anaesthetized rats. Elevated tissue levels of nitric oxide (NO) and prostaglandins possibly contribute to this observation. The aim of this study was to compare the effects of luminal capsaicin (1.2 mg mL-1), ethanol (15%) and high partial pressure of CO2 (>250 mmHg) with those of HCl (10 mM) in anaesthetized rats. Motility (intraluminal pressure), mucosal permeability [blood-to-lumen clearance of 51Cr-EDTA (51Chromium-labelled ethylenediaminetetraacetate)] and duodenal mucosal bicarbonate secretion (DMBS) were recorded. Three groups of animals were studied: (1) controls, (2) pretreatment with the NO synthase inhibitor N-nitro-L-arginine-methyl-ester (L-NAME) and (3) pretreatment with the cyclo-oxygenase inhibitor indomethacin. Neither capsaicin, ethanol, CO2 nor HCl induced duodenal contractions or affected DMBS in control rats. However, L-NAME induced duodenal contractions that were augmented by capsaicin, ethanol and HCl, but not by CO2. Indomethacin also induced contractions that were reversibly diminished by capsaicin and HCl, but not by ethanol or CO2. Significant increases in mucosal permeability occurred during ethanol perfusion in indomethacin- and L-NAME pretreated rats. In conclusion, NO probably plays a key role in preventing duodenal contractions in response to luminally HCl, capsaicin and ethanol. The HCl-induced effect on motility appears to be independent of CO2 and is not caused by alteration in mucosal integrity.

Fibreoptic endoscopy and the use of the Sengstaken tube in acute gastrointestinal haemorrhage in patients with portal hypertension and varices.

The value of emergency upper gastrointestinal fibre-endoscopy, followed where required by the use of a modified Sengstaken tube, was studied during 84 episodes of acute bleeding in 75 patients who had evidence of portal hypertension with varices. The portal hypertension was due to alcoholic cirrhosis in 80% and to cryptogenic cirrhosis in 9% of the patients. By definition, varices were present in all patients, but in only 66% of episodes were the varices the cause of the bleed. The correct diagnosis of the source of bleeding was made at endoscopy in 89%. A Boyce modification of the Sengstaken-Blakemore tube was passed in 73% of the episodes of variceal bleeding. It effectively stopped the bleeding primarily in 85% of patients but was successful as a final definitive measure only in 46%. Furthermore, only 40% of the patients in whom the tube was passed, survived. Mortality rate could be related to the severity of the bleed and to hepatocellular dysfunction. Survival increased from 23% in those patients with jaundice, ascites, and encephalopathy on admission to 92% in those without these manifestations. The in-hospital survival rate was 52% in patients bleeding from varices and 64% in those bleeding from other causes, with an overall survival rate of 56%, indicating the poor prognosis in cirrhotic patients with gastrointestinal bleeding, irrespective of the cause.

Percutaneous gastrostomy with fluoroscopic guidance: single-center experience in 500 consecutive cancer patients.

PURPOSE: To evaluate the feasibility, complications, adequacy of feeding support, and tolerability of fluoroscopically guided gastrostomy in cancer patients. MATERIALS AND METHODS: Five hundred cancer patients were referred for fluoroscopically guided gastrostomy, among whom percutaneous endoscopic gastrostomy was contraindicated or had been unsuccessful in approximately one-fourth. Five hundred eight fluoroscopically guided gastrostomies with T-fastener gastropexy were performed in 496 patients. The procedure was unsuccessful in four patients, and 12 patients needed a second gastrostomy. RESULTS: Fluoroscopically guided gastrostomy was feasible in 99% of patients. During the first 30 postprocedure days, there were seven major complications (1.4%): cardiac failure (n = 1), hemorrhage (n = 1), and peritonitis (n = 5); one patient died of peritonitis. No major complications occurred after the 30th postprocedure day. There were 27 minor complications (5.4%) during the first 30 postprocedure days and 88 (17.6%) thereafter. Long-term minor complications mainly involved the disturbances and nearly always resolved once the tube was exchanged. Such exchanges were easily performed under fluoroscopic guidance except in two patients, who required repeat fluoroscopically guided gastrostomy. CONCLUSION: Fluoroscopically guided gastrostomy is highly feasible and safe and provides adequate feeding support, even when percutaneous endoscopic gastrostomy is impossible. Long-term complications, which are mainly tube disturbances, are easily treated.
