Eosinophilic gastroenteritis.

Eosinophilic gastroenteritis is a rare condition of unknown etiology characterized by peripheral eosinophilia, eosinophilic infiltration of the gastrointestinal tract, and gastrointestinal symptomatology. Eosinophilic gastroenteritis is generally classified according to the layer of gastrointestinal tract involved. Mucosal involvement may result in abdominal pain, nausea, vomiting, diarrhea, weight loss, anemia, protein-losing enteropathy, and intestinal perforation. Patients with muscular layer disease generally have obstructive symptoms. Subserosal eosinophilic infiltration may result in development of eosinophilic ascites. Patients with mild and sporadic symptoms can be managed with reassurance and expectant observation. Patients with disabling symptoms can be effectively treated with corticosteroids after other systemic disorders associated with peripheral eosinophilia have been excluded. Occasionally, sodium cromolyn, ketotifen, and/or elimination diets have been shown to be effective in the management of patients who have a significant history of allergic disorder. Surgical intervention may be required in patients with obstructive complications or refractory disease.

Patent ductus arteriosus in micropreemies and full-term infants: the relative merits of surgical ligation versus indomethacin treatment.

BACKGROUND/PURPOSE: Treatment of ductus arteriosus is controversial. The merits and timing of ductus ligation versus indomethacin treatment were compared. METHODS: Study parameters for infants with PDA (June 1988 through March 2001) included age, weight, physical findings, echocardiograph, success/complications of treatment, and length of stay (LOS). Statistical analysis was by descriptive univariate analysis. RESULTS: Two hundred twelve infants were included. Median gestational age was 26 weeks (range, 22-38); weight, 836 g (447 to 2,863). Findings included murmur (94%), congestion (20%), cardiomegaly (15%), bounding pulses (6%), hyperdynamic precordium (4%), and CHF (2%). Echocardiographic measurements were left atrial diameter, 0.92 cm; posterior wall thickness, 0.26 cm; PDA diameter, 2.5 mm; septal thickness, 0.27 cm; aortic root diameter, 0.64 cm; ejection fraction, 39%; left ventricular internal diameter-diastole, 1.3 cm; left ventricular internal diameter-systole, 0.82 cm; right ventricular internal diameter-diastole, 0.51 cm. No measurement, except PDA diameter, was predictive of medical failure or need for reoperation. However, weight less than 1,000 g was highly predictive of medical failure. Additional cardiac anomalies included ASD (69%), VSD (3%), and aortic coarctation (1%). One hundred sixty-seven babies (79%) received indomethacin, closing the PDA in 88 cases (53%, recurrence = 47%). Indomethacin complications (73%) included thrombocytopenia (36%), BUN increase (31%), sepsis (30%), oliguria (25%), hyponatremia (25%), IVH (16%), pulmonary interstitial emphysema (11%), NEC (8%), intestinal perforation (4%), and bleeding (3%). Seventy-seven babies (36%) required operations (92% in the NICU) performed by pediatric surgeons. Ligation criteria included hypoxia, hypercapnia, decreasing compliance, CHF, and contraindications/failure of indomethacin. Complications included pneumothorax (4%), IVH (4%), bleeding (4%), NEC (1%), and wound infection (1%). LOS averaged 82 days. CONCLUSIONS: Although indomethacin therapy is a reasonable treatment alternative, it is associated with significant complications. Ductus ligation may be preferable, especially in very low birth weight babies, because it is associated with low morbidity and almost certain degree of success.

Perforation due to metastatic tumors of the ileocecal region.

We reviewed our department's medical records between April 1986 and April 1994 to identify patients who showed acute abdominal symptoms requiring surgical treatment due to metastatic tumors of the small intestine. In group A, seven patients (30%) were treated for acute peritonitis, and all were found to have an intestinal perforation due to hematogenous metastases (group A). In group B, 16 patients (70%) were treated for an intestinal obstruction, and all were found to have disseminated tumors of the small intestine (group B). In group A all tumors were isolated and located exclusively in the ileocecal region, whereas all tumors in group B showed peritoneal dissemination, with no predominant anatomic localization. In general, the intestinal tumors in group A originated from cancers of the upper aerodigestive tract, whereas those in group B originated from advanced cancers in the abdominal cavity. The tumors were significantly smaller and the period between the onset of symptoms from the original malignancy and the onset of abdominal symptoms (perforation or obstruction) was significantly shorter in group A. In conclusion, intestinal metastases located in the ileocecal region have unique clinicopathologic features and so should be recognized as a distinct disease entity. Therefore when patients with a known upper aerodigestive malignancy exhibit acute abdominal symptoms, intestinal metastasis to the ileocecal region, necrotic changes, and perforation should be considered in the differential diagnosis.

Treatment of non-Hodgkin's lymphoma in Mexican children. The effectiveness of chemotherapy during malnutrition.

The histological diagnosis of non-Hodgkin's lymphoma (Burkitt's lymphoma excluded) in 147 children was reviewed. The most common site of presentation was in the abdomen (32.6%). The most frequent site of metastatic disease at diagnosis was the bone marrow (27.2%). The most common histology was diffuse undifferentiated non-Burkitt type (37.4%). According to the Murphy staging system, 40.1% were stage III and 27.2% were stage IV. In a nonrandomized prospective study, 121 patients were submitted to a treatment regimen (protocol 8001) and compared with 26 historical controls treated with the COP regimen, consisting of cyclophosphamide, vincristine, and prednisone. Of those patients treated with protocol 8001, nine had intestinal perforation at the site of primary disease. All patients in this group were malnourished at the time of perforation. The overall rate of initial complete remission in those patients treated with protocol 8001 was 90.7%. The duration of remission was from 16 to 108 months, with a median of 39 months. The actuarial rate of disease-free survival was 69% at 2 years and 63% at 6 years, compared with 36% at 6 years of the control group (COP) (p less than 0.01). None of the patients have relapsed after 4 years.

Perforation of the gastro-intestinal tract by a foreign body. A case report.

Most ingested foreign bodies pass through the gastro-intestinal tract without giving rise to complications. If they become lodged in a narrow segment of the gastro-intestinal tract, perforation may occur. The resulting morbidity depends on the further route of the penetrating object and whether septic sequelae ensue. This article describes an unusual case of foreign body perforation with a protracted clinical course. It emphasises that there are no insurmountable barriers in the pathway of foreign bodies.

Influence of sex on clinical features, laboratory findings, and complications of typhoid fever.

Clinical features, laboratory findings, and complications of typhoid fever were correlated with sex through a retrospective case note review of 102 hospitalized culture-positive patients in Durban, South Africa. Intestinal perforation (P = 0.04), occult blood losses in stools (P = 0.04), and a mild reticulocytosis in the absence of hemolysis (P = 0.02) occurred more frequently in males than in females. A single pretreatment Widal O antibody titer > or = 1:640 was also a statistically significant occurrence in males (P = 0. 006). Female patients were significantly more severely ill (P = 0.0004) on admission and had chest signs consistent with bronchopneumonia (P = 0.04), transverse myelitis (P = 0.04), abnormal liver function test results (P = 0.0003), and abnormal findings in urinalyses (P = 0.02). Typhoid hepatitis (P = 0.04) and glomerulonephritis (P = 0.02) were present significantly more frequently in females. Whether these differences were due to differences in host's immune response to acute infection need to be determined in a prospective study.

Potentially lethal complications of shigellosis.

Complications that can lead to death during shigellosis include intestinal as well as systemic manifestations. The former include intestinal perforation, toxic megacolon, and dehydration, and the latter include sepsis, hyponatremia, hypoglycemia, seizures and encephalopathy, hemolyticuremic syndrome, pneumonia, and malnutrition. Data on the frequency of these complications come primarily from hospital-based studies, in which sepsis-either with Shigella or with other Enterobacteriaceae-and hypoglycemia are the most common causes of death. Management of these two complications requires broad-spectrum empiric antibiotic treatment of all severely ill, malnourished patients with shigellosis as well as frequent feedings to prevent hypoglycemia. Unfortunately, in developing countries, access to parenteral broad-spectrum antimicrobial agents is often limited, and frequent feedings are often precluded by the severe anorexia that is characteristic of shigellosis. Realistic approaches to the reduction of mortality from shigellosis must continue to focus on prevention and early antimicrobial therapy rather than on treatment of established complications.

Aerobic and anaerobic microbiology in intra-abdominal infections associated with diverticulitis.

The aerobic and anaerobic microbiology of intra-abdominal infections associated with diverticulitis was studied in 110 specimens from the peritoneal cavity after intestinal perforation and in 22 specimens from abdominal abscesses. Anaerobic bacteria only were isolated from 17 (15%) of the peritoneal specimens, aerobic bacteria only from 12 (11%) and mixed aerobic and anaerobic flora from 81 (74%). A total of 339 bacterial isolates was detected in peritoneal cultures (3.1 per specimen), comprising 155 aerobes (1.4 per specimen) and 184 anaerobes (1.7 per specimen). Anaerobic bacteria only were isolated in 4 (18%) abscesses, aerobes alone in one (5%) and mixed aerobic and anaerobic flora in 17 (77%). A total of 72 bacterial isolates (3.3 per specimen) was detected in abdominal abscesses - 35 aerobes (1.6 per specimen) and 37 aerobes (1.7 per specimen). The predominant aerobic and facultative bacteria in abdominal infections were Escherichia coli and Streptococcus spp. The most frequently isolated anaerobes were Bacteroides spp. (B. fragilis group), Peptostreptococcus, Clostridium and Fusobacterium spp.

Treatment of severe intra-abdominal sepsis and/or necrotic foci by an 'open-abdomen' approach. Zipper and zipper-mesh techniques.

Undrained necrotic tissue or septic foci contribute to continued "activation" of host processes that in turn lead to multiple organ failure and death. We hypothesized that if wide-open drainage of the abdominal cavity is provided, thus not allowing intra-abdominal collections to form, mortality in these patients can be reduced. Since 1982 we have treated 49 patients with necrotic pancreatitis and related infections and 15 patients with severe intra-abdominal sepsis from intestinal perforations. The surgical treatment was based on the provision for daily laparotomies in the intensive care unit with the patient under epidural anesthesia by using an "open-abdomen" technique (zipper alone or a zipper-mesh combination). The APACHE II score and the functional classification were used to derive expected mortalities. The patients with intraabdominal sepsis had a mean APACHE II score of 25 and an expected mortality of 45%, vs the 26.5% mortality that we observed. The lowest mortality in the necrotic pancreatitis group was associated with noninfected pancreatic necrosis (6%) and single abscess (9%) vs 22% mortality rate in the patients with infected pancreatic necrosis. The mean expected mortality in this group was 47%, vs the observed 22%. We attributed this result to the daily abdominal explorations that achieved a complete excision of infected or necrotic tissue.

AIDS and the gut.

There are increasing challenges for the practising gastroenterologist in treating AIDS-related gastrointestinal diseases. The differential diagnoses of dysphagia and odynophagia include cytomegalovirus (CMV) and herpes simplex virus (HSV) infection, non-specific aphthous ulceration and non-AIDS oesophageal diseases, especially reflux oesophagitis. Chronic subacute abdominal pain with nausea, vomiting, early satiety and weight loss is suggestive of an obstructive lesion caused by lymphoma or Kaposi's sarcoma. Severe acute abdominal pain can indicate pancreatitis or intestinal perforation due to cytomegalovirus. Right upper quadrant pain (with or without fever, vomiting or abnormal liver function tests with a cholestatic profile) is suggestive of hepatobiliary pathology including cholecystitis, cholangitis, acalculous cholecystitis and AIDS cholangiopathy. Diarrhoea is the most common gastrointestinal symptom of AIDS, affecting 50-90% of patients. Causes of AIDS diarrhoea include protozoa (Cryptosporidium parvum, Isospora belli, Enterocytozoon bieneusi, Septata intestinalis, Cyclospora spp, Entamoeba histolytica and Giardia lamblia), bacteria (Mycobacterium avium-intracellulare, Clostridium difficile, Salmonella, Shigella and Campylobacter jejuni), and viruses (CMV, HSV and possibly HIV). Chronic diarrhoea, malnutrition and weight loss can shorten the life-span of patients with AIDS. Elemental diets, isotonic formulas, medium chain triglycerides and total parenteral nutrition have been tried with little success in AIDS patients with severe diarrhoea and wasting.

Intra-operative saline irrigation of the peritoneal cavity in experimental post-traumatic peritonitis.

A trial of intra-operative saline irrigation of the peritoneal cavity for the prevention of peritonitis was conducted in an animal model. Following abdominal missile injury with intestinal perforation, 43 anaesthetized pigs were operated on an randomly assigned to three treatment groups. In two of the groups intraperitoneal irrigation with 3 litres of saline solution was performed during the operation, using a jet technique in one group. A control group of pigs received no irrigation. The effect of irrigation was evaluated with quantitative bacteriologic studies of peritoneal exudate and peritoneal biopsy specimens. Continuous anaesthesia and assisted ventilation were used and the post-trauma observation period was 3 days. The average bacterial density in the peritoneal exudate decreased by more than 99% in all treatment groups during the operation, but increased to more than the pre-irrigation level during the observation period. Irrigation did not result in significantly greater elimination of the bacterial population. The mortality was not lower in irrigated animals than in the controls. Intra-operative saline irrigation thus did not prevent peritonitis in this experimental model.

A case of Crohn's disease involving the gallbladder.

Crohn's disease is well known to affect any part of the gastrointestinal tract including the oral cavity and anus. Various extraintestinal complications have been reported in Crohn's disease, but extraintestinal involvement characterized by granulomatous lesions is uncommon. Here, we have reported a case about the involvement of the gallbladder in Crohn's disease. A 33-year-old woman was diagnosed having panperitonitis due to intestinal perforation and cholecystitis. The patient was moved to the surgical service for an emergency operation. On the resected specimen, there was a broad longitudinal ulcer at the mesenteric side. The mucosa of the gallbladder was nodular and granular, and the wall was thickened. The surface epithelium of the gallbladder was partially eroded and pyloric gland metaplasia was observed focally. Rokitansky-Aschoff sinuses were also present. From the lamina propria to the subserosal layer, there were several well-formed epithelioid cell granulomas, which were the non-caseating sarcoidal type different from the foreign-body and xanthomatous granulomas. Periodic-acid Schiff and acid fast stains revealed no organism within the granulomas. Lymphoid aggregates were present throughout the gallbladder wall. Sections from the resected ileum showed typical features of the Crohn's disease. When cholecystectomy is performed in a patient with Crohn's disease, the possibility of gallbladder involvement should be carefully examined by histopathological tests.

Laparoscopic vs percutaneous endoscopic gastrostomy tube insertion: a new pediatric gold standard?

BACKGROUND/PURPOSE: Gastrostomy tube insertion is frequently performed in children. Percutaneous endoscopic gastrostomy (PEG) insertion, considered by many to be the "gold standard," is unavoidably associated with a risk of intestinal perforation and frequently requires a second anesthetic for its replacement with a low-profile "button." We hypothesized that a laparoscopic technique with low-pressure insufflation would yield comparable outcomes, a lower procedural complication rate, and require fewer anesthetics per patient. METHODS: A retrospective review of all surgeon-placed gastrostomy tubes (exclusive of those associated with fundoplication or other procedures) between January 2002 and December 2003 was undertaken. Data collected included type of procedure (PEG vs laparoscopic), indication, patient demographics (including neurologic comorbidity), operative time, complications (procedure-specific and nonspecific), and number of procedural anesthetics to "achieve" a low-profile tube. Groups were compared by univariate and multiple logistic regression analyses. RESULTS: One hundred nineteen gastrostomy tubes (26 laparoscopic = 21.8%) were inserted. The PEG and laparoscopic gastrostomy groups were comparable from the perspectives of age, size, indications for tube placement, and operative time. The complication rate after PEG placement was significantly higher than after LG (14% vs 7.7%; P = .023), and 72 (77.4%) of PEG patients required a second anesthetic for tube change. CONCLUSIONS: Laparoscopic gastrostomy tube insertion is safe and easy to perform, with outcomes comparable to that of PEG tube insertion. It obviates the need for a second procedural anesthetic and may emerge as the gold standard for gastrostomy tube placement.

Neonatal gut injury and infection rate: impact of surgical debridement on outcome.

Infectious burden of gut injury (G-INJ) associated with necrotizing enterocolitis (NEC) or with spontaneous intestinal perforation (SIP) in neonates has not been ascertained. We sought to test the hypotheses that: (1) infants with G-INJ develop higher number of infections including non-concurrent infections than infants without G-INJ in a neonatal intensive care unit (NICU); (2) surgical debridement (DEB) of infants with severe G-INJ is associated with lower infectious morbidity and mortality. All infants admitted to the regional NICU from October 1991 to February 2003 were included in this prospective prevalence investigation of G-INJ and infections. Non-viable (<23 week gestational age) infants, infants with congenital anomalies, and those who developed NEC after SIP were excluded. Standard definitions of National Centers for Disease Control and Prevention were used for different categories of infections. Episodes of infections were classified as concurrent or non-concurrent (post G-INJ) based upon their timing in association with G-INJ. Infants with G-INJ associated with Bell stage II or higher NEC or with SIP were further stratified by DEB into two subgroups. A previously described 7-point clinical score was used to divide G-INJ into mild (0-2), moderate (3-5), and severe (6-7) categories. Surgical outcomes were determined by using chi(2) and logistic regression analyses. Data are expressed as mean +/- SD or as odds ratio (OR) with 95% confidence intervals (CI); P < 0.05 was considered significant. Of all 5,481 infants, 954 (17.4%) developed 1,734 episodes of infections. Prevalence of G-INJ was 4% (n = 222); of these, 33% (n = 73) underwent DEB. Infants with G-INJ had lower mean birth weight (1,414+/-766 vs. 2,153+/-104 g; P < 0.0001) and lower mean gestational age (29.6+/-4.2 vs. 32.9+/-4.8 weeks; P < 0.0001) than their peers (n = 5,259). Controlling for birth weight and gestational age, odds for non-concurrent blood stream infections (BSIs) in G-INJ infants were higher (OR 13.98, CI 10.289-19.01, P < 0.0001) than the remaining population without G-INJ. Forty-four percent of all episodes of fungemia, 32% of all episodes of BSIs occurred in G-INJ infants (P < 0.0001). Within the G-INJ group, there were no demographic differences between the DEB and non-DEB infants. Controlling for severity of G-INJ, odds for non-concurrent BSIs (OR 3.45, CI 1.04-11.36, P < 0.05) and for mortality (OR 3.35, CI 1-10, P < 0.05) among non-DEB infants were higher than in DEB infants. Infants with G-INJ suffered from a disproportionate number of all blood-stream infections in our intensive care nursery. Infants with severe G-INJ whose management includes DEB are more likely to survive and to incur less infectious morbidity.
