Spontaneous localized intestinal perforation and intestinal dilatation in very-low-birthweight infants.

AIM: To elucidate how spontaneous localized intestinal perforation (SLIP) is related to intestinal morphological features such as dilatation in very-low-birthweight (VLBW) infants. METHODS: The medical records of 13 VLBW infants (<1500 g) undergoing laparotomy between 1983 and 2003 for presumed SLIP were retrospectively reviewed. Clinical findings including maternal, prenatal and perinatal factors were analysed, and the clinical and surgical findings upon laparotomy were compared. RESULTS: Postnatal pathological conditions included patent ductus arteriosus (n=7), sepsis (n=2), respiratory distress syndrome (n=7), intraventricular haemorrhage (n=2), an indwelling catheter via the umbilical vein (n=1) and pneumonia (n=1). Indomethacin was used in seven neonates with patent ductus arteriosus, and dexamethasone preventive therapy was employed in one neonate for bronchopulmonary dysplasia. Operative findings revealed a localized small punched-out perforation in the ileum. Five patients had intestinal dilatation: two with a perforation in the middle of the dilated intestine, and three with a perforation proximal to the region of dilatation. The muscularis propria was absent in the dilated intestine of four patients. CONCLUSION: This study found no significant relationship between perforation and dilatation of the intestine. Perforation may occur in any portion of the ischaemic intestine when circulatory failure becomes severe, and is not necessarily restricted to the dilated intestine. We believe that SLIP and intestinal dilatation may occur on the same basis in low-birthweight infants; however, the disease process may be aetiologically different.

New insights into spontaneous intestinal perforation using a national data set (3): antenatal steroids have no adverse association with spontaneous intestinal perforation.

OBJECTIVE: To examine whether antenatal steroids (ANS), alone or with early indomethacin, are associated with spontaneous intestinal perforation (SIP). SIP is a known complication of concurrent post-natal administration of glucocorticoid and indomethacin in extremely low birth weight (ELBW) infants. STUDY DESIGN: A large de-identified national data set was retrospectively examined for infants with SIP without any report of other malformation or necrotizing entrocolitis. A control group was then derived matching for gender and birth weight (+/- 20 g). Pre- and post-natal variables were tested by both univariate and multivariate analysis to identify associations with SIP. RESULTS: From January 1996 to June 2004, there were 2 27 711 discharges from Pediatrix neonatal intensive care unit sites. From this population 388 infants with SIP associated with ELBW were compared to matched controls. Infants with SIP were more likely to have received early indomethacin and to have received a combination of early indomethacin with post-natal glucocorticoids (P < 0.05 for both). When used alone (without subsequent indomethacin), ANS showed no association with SIP. When used in conjunction with indomethacin, ANS did not increase the rate of SIP beyond indomethacin alone. CONCLUSION: ELBW Infants that acquire SIP were more likely to have been exposed to early indomethacin and post-natal glucocorticoids. However, no association was found between SIP and ANS within a well-powered cohort.

Neonatal intestinal perforation caused by intestinal muscularis defect associated with vascular ectasia.

We describe a rare case of a viable preterm infant who developed a spontaneous localized perforation of the small bowel caused by a segmental absence of the intestinal musculature and associated with vascular ectasia. The findings may support a causal relationship between absence of the intestinal muscle coat and a vascular network disorder which may be responsible for the gastroenteric defect.

New insights into spontaneous intestinal perforation using a national data set: (2) two populations of patients with perforations.

BACKGROUND: Spontaneous intestinal perforation (SIP) is increasingly common in the premature infant and has been demonstrated to be associated with early postnatal administration of glucocorticoids and indomethacin. Before survival of the extremely low birth weight (ELBW) infant, SIP was thought to be a rare, congenitally acquired disease sporadically affecting the muscularis of the distal intestine. These disparate views of etiology have not been previously reconciled in the literature. OBJECTIVES: (1) To establish a cohort of SIP patients in a national data set. (2) To use timing of diagnosis as a unique data element and thereby differentiate between SIP cases which are susceptible to postnatal risk factors versus those occurring at or immediately after birth (and therefore not exposed to postnatal risk factors). METHODS: A large identified national data set was used to retrospectively look at timing of diagnosis and then the cohort was divided into postnatal treatment groups for further subanalyses. This analysis resulted in the division of the cohort into early and late diagnosis SIP subcohorts. These were then queried retrospectively by univariate analysis to look for differences in demographics between the two (using a P-value < 0.05). RESULTS: There were 633 patients with SIP evaluated in this data set. The early SIP cohort (0-3 days) was made up of 116 infants with a median BW of 1.401 kg, whereas the late cohort (4-14 days) held 386 infants with a median BW of 775 g. Infants with early SIP were significantly more likely to: be male, have higher Apgar scores, have not received antenatal steroids, surfactant or required mechanical ventilation. CONCLUSIONS: Two populations of infants acquire SIP: ELBW infants acquire SIP on average between 7 and 10 days of life after exposure to indomethacin and glucocorticoids (either endogenous or exogenous), and infants with early SIP (0-3 days) who are significantly less likely to have been exposed to postnatal risk factors and are less premature.

[Intestinal perforation caused by chicken bone mimicking perforated colonic diverticulitis].

Intestinal Perforation can occur in less than 1% of cases of ingestion of foreign bodies. Clinical suspicion is very important to make the diagnosis since many medical conditions can simulate this pathology. We present a case of a 63 years old man who swallowed a chicken bone that perforated the sigmoid colon and produced a clinical picture mimicking a perforated colonic diverticulitis. At surgery, the bone was removed without any evidence of abscess formation. A Hartmann procedure was performed and we reanastomosed it 3 month later. The patient followed an uneventful postoperative course. We demonstrated that early detection and opportune surgical treatment decrease the risk of developing complications such as abscess formation, intestinal fistula or obstruction.

Comparative study between isolated intestinal perforation and necrotizing enterocolitis.

INTRODUCTION: Intestinal perforations in the neonatal period are usually related to necrotizing enterocolitis (NEC) or intestinal occlusion. Intestinal perforation in the absence of these conditions is called isolated perforation (IP). Several risk factors and pathogenic mechanisms have been suggested, and most of them are common to those classically attributed to NEC. AIM: To identify and compare the clinical and pathological features of IP and NEC. MATERIAL AND METHODS: We reviewed all cases of neonatal intestinal perforation and NEC in the last five years. Thirty-three patients were retrospectively classified into Group NEC: 24 cases, and Group IP: 9 cases. We collected multiple data as study variables: 1) General features; 2) Obstetric history; 3) Neonatal treatment; 4) Comorbidity; 5) Perforation features; 6) Treatment and outcome. RESULTS: Comparing the groups, we found statistical significant differences in isolated perforation cases with these risk factors: extreme prematurity, very low birth weight, abruptio placenta, intubation and neonatal mechanical ventilation, umbilical catheterization, precocious sepsis, and indomethacin therapy. A more precocious operation and a good prognosis also reached statistical significance. In the other hand, we found statistically significant differences in NEC with congenital cardiopathy (excluding isolated patent ductus arteriosus), with intestinal pneumatosis, with diffuse bowel involvement and a worse prognosis. Risk factors and pathologic findings seem to support an ischaemic pathogenesis in both diseases.

[A case of systemic lupus erythematosus developed with intestinal perforation].

A case of intestinal perforation associated with SLE is presented. A 54-year-old woman was diagnosed as having SLE twenty-five years ago when she had facial erythema, photosensitivity, oral aphtha, polyarthraliga, leukopenia, positive LE cell and positive antinuclear antibody. She had been treated with prednisolone and admitted to Kushiro City General Hospital because of one month history of fever and anorexia in February 1996. Laboratory findings did not reveal activity of SLE, and a diagnosis of urinary tract infection was made based on the findings of urinalysis. After severe diarrhea, disseminated intravascular coagulation (DIC) developed. A rectal perforation was revealed by endoscopic and radiological examination. An emergency laparotomy revealed necrosis of the rectum and sigmoidostomy was performed. The biopsied specimen of the rectum were diagnosed as gangrene of ischemic colitis histologically. Because of a penetration to the urinary bladder, an ureterocutaneostomy was performed. She died of sepsis and DIC on the 127th day of admission. Only 11 cases of intestinal perforation associated with SLE have been reported in Japan, and the association of vasculitis has been considered. In the present case, the prolonged use of prednisolone might cause the necrotizing ischemic colitis.

[Spontaneous intestinal perforation in premature infants].

BACKGROUND: Spontaneous intestinal perforations mainly affect preterms within their first two weeks of life. PATHOGENESIS: In contrast to the findings in necrotizing enterocolitis demarcations due to spontaneous perforations are sharply punched out of an otherwise vital bowel section. Pathophysiologic interactions currently are poorly understood. Arterial hypotension and vascular compromises seem to play a crucial role in the development of spontaneous intestinal perforations. CLINICAL ASPECTS: Clinical characteristics are abdominal distension and green-blue discolouration in association with a stable general condition. Intestinal perforations require surgical intervention in terms of primary anastomosis or barrelled stoma, for instance. Spontaneous perforations carry favourable prognosis with a rare chance of relapses.

Spontaneous neonatal and fetal intestinal perforation.

Apparently spontaneous neonatal intestinal perforation may be difficult to diagnose if the condition is not kept in mind. It may present with free perforation or with the late effects of meconium peritonitis. Five cases are described. There is a high mortality associated with bacterial peritonitis, and the importance of early diagnosis and energetic resuscitation is underlined.

Intestinal perforation due to Mycobacterium tuberculosis in HIV-infected individuals: report of two cases.

Intestinal perforation is an extremely uncommon complication of Mycobacterium tuberculosis (MTB) infection. We describe two cases of multiple intestinal perforations secondary to MTB in individuals infected with the human immunodeficiency virus (HIV) presenting at the Los Angeles County-University of Southern California Medical Center over a 2-month period. For each case, this was the first presentation of AIDS. One of the two patients had concurrent pulmonary involvement. One patient died, and the other responded to therapy and was discharged in stable condition. The most striking finding in both cases was the extremely large number of acid-fast bacteria seen transmurally on the pathological specimens. This might be related to impaired T-cell function. The resurgence of MTB infection in North America, in the presence of the AIDS epidemic, may result in an increasing frequency of unusual presentations, such as intestinal perforation. Intestinal perforation due to MTB should be considered in HIV-infected patients presenting with an acute abdomen.

Factors associated with intestinal perforation in children's non-typhi Salmonella toxic megacolon.

BACKGROUND: To evaluate the risk factors for intestinal perforation in children with toxic megacolon caused by non-typhi Salmonella infection. METHODS: During an 11-year period we reviewed the records of children treated for non-typhi Salmonella infection. All of the subjects had positive stool culture for non-typhi Salmonella and were treated with intravenous ceftriaxone during hospitalization. Clinical data reviewed included demographic features, clinical manifestations, laboratory findings, radiologic findings, microbiology, therapeutic effect of hydration and rectal tube placement and the operative findings. Patients with toxic megacolon were defined as those having toxic appearance, diarrhea, high fever (>39 degrees C) and marked colon dilatation with maximal diameter > 1.5 times the width of the vertebra body of the first lumbar spine (L1-VB). To define the risk factors for patients with toxic megacolon complicated by intestinal perforation, patients were divided into two groups for analysis: P group, those complicated with intestinal perforation; and NP group, those without intestinal perforation. Differences in age, sex, severity of diarrhea, duration of fever, hemogram and its differential, culture, stool analysis, serum C-reactive protein (CRP), electrolytes, maximal colon diameter, medical therapy and timing of rectal tube insertion between the two groups were analyzed. Statistical analyses were conducted with chi square tests and multiple logistic regression. RESULTS: A total of 75 patients (P group, 27 patients; NP group, 48 patients) ages 4 months to 6 years were evaluated. With chi square analysis 7 variables were found to be significantly associated with intestinal perforation: age >1 year; fever >5 days; ratio of immature to total neutrophils >20%; serum CRP >200 mg/l; colon diameter >2.5 times the width of L1-VB; inadequate early hydration; and delay in rectal tube insertion. With multivariate analysis age >1 year, serum CRP >200 mg/l and colon diameter >2.5 times of width of L1-VB, inadequate early hydration and delay in rectal tube insertion were the most significant factors associated with intestinal perforation. CONCLUSION: Identification of patients with toxic megacolon associated with non-typhi Salmonella infection at risk for further intestinal perforation is possible. Early effective fluid resuscitation and rectal tube insertion may be helpful to prevent the occurrence of intestinal perforation.

Intestinal perforation due to cytomegalovirus infection in patients with AIDS.

Intestinal perforation due to cytomegalovirus (CMV) infection in patients with AIDS is the most common life-threatening condition requiring emergency celiotomy in these patients. The authors describe a patient with AIDS with intestinal perforation due to CMV infection, and review 14 additional cases reported in the English-language surgical literature. The diagnostic triad of pneumoperitoneum on x-ray, evidence or history of CMV infection, and AIDS occurred in 70 percent of patients. The most common site of intestinal perforation was the colon (53 percent), followed in frequency by the distal ileum (40 percent) and appendix (7 percent); perforation usually occurred between the distal ileum and splenic flexure of the colon. Colonoscopy, rather than sigmoidoscopy, is recommended as a screening examination in patients with AIDS suspected of having colonic ulceration due to CMV infection. Multiple biopsies of ulcerated tissue should be obtained. Gross and microscopic analyses of involved intestinal tissue reveal the characteristic findings of ulceration and CMV infection. Despite aggressive therapy, the operative mortality rate in patients with AIDS with intestinal perforation due to CMV infection was 54 percent and the overall mortality rate was 87 percent. Postoperative complications occurred in most patients and consisted mainly of systemic sepsis and pneumonia caused by Pneumocystis carinii infection. An increased awareness of this syndrome by physicians frequently called on to manage patients with AIDS is recommended.

Surgery for intestinal perforation in preterm neonates: anastomosis vs stoma.

BACKGROUND: Traditionally, a stoma is established after resection of perforated or necrotic intestine for isolated intestinal perforation (IIP) and necrotizing enterocolitis (NEC). We compared the outcome of resection and anastomosis (RA) with stoma formation (RS). METHODS: Sixty-eight neonates undergoing laparotomy for IIP (n = 20), NEC (n = 43), and indeterminate cause (n = 5) were reviewed retrospectively. Intestinal resection was followed by either anastomosis or stoma. The primary outcome measure was the frequency of anastomosis- and stoma-related complications. RESULTS: The median gestational age (GA) was 28.5 weeks and birth weight (BW) was 940 g. Thirty-seven neonates had RA (NEC 22, IIP 14, 1 unknown), 28 RS (NEC 21, IIP 6, 1 unknown), and 3 laparotomy only. Twenty-five neonates died postoperatively. The mean +/- SD GA of those who survived was 30 +/- 4.5 weeks and those who died was 27.2 +/- 3.5 weeks (P = .008). The mean BW for those that survived was 1440.5 +/- 865.1 g and those who died was 827.7 +/- 385.1 g (P = .002). There was no statistically significant difference between the RA and RS groups for GA (P = .93), BW (P = .4), general complications (P = .96), anastomosis and stoma complications (P = .48), and deaths (P = .42). CONCLUSIONS: RA, rather than stoma, is an acceptable option in the surgical management of preterm neonates with IIP or NEC.

Peritoneal drainage as definitive treatment for neonates with isolated intestinal perforation.

BACKGROUND/PURPOSE: To better define the indications for peritoneal drainage (PD) in premature babies with intestinal perforation, the authors reviewed their experience with this procedure in a tertiary neonatal intensive care setting. METHODS: The charts of all neonates who underwent PD as initial treatment for intestinal perforation between 1996 and 1999 were reviewed. Those patients with pneumatosis intestinalis on abdominal radiograph had perforated necrotizing enterocolitis (NEC) diagnosed; whereas, those infants with no pneumatosis had isolated intestinal perforation diagnosed. The clinical characteristics and outcomes of these 2 groups were compared. RESULTS: Twenty-one premature neonates had primary PD between 1996 and 1999, 10 for isolated intestinal perforation and 11 for perforated NEC. Patients with isolated intestinal perforation had lower birth weights (708 v 949 g; P < .05), were less likely to have started feedings (30% v 91%, P < .05), and the perforation developed at an earlier age (10.6 v 28.0 d, P < .05) compared with the patients who had perforated NEC. Only 2 of 10 infants with isolated perforation required subsequent laparotomy (at 10 weeks for stricture and 12 weeks for a persistent fistula). For these patients, the long-term survival rate was 90%. In contrast, 8 of 11 infants with perforated NEC required laparotomy, and although the 30-day survival rate was 64%, the long-term survival rate was only 27%. CONCLUSIONS: Peritoneal drainage provides successful and definitive treatment for most premature babies with isolated intestinal perforation. For neonates with perforation caused by NEC, peritoneal drainage may provide temporary stabilization, but most of these infants require subsequent laparotomy, and few survive.
