Gastrocolic Fistula is, in the majority of cases the pathological communication between stomach and transverse colon. It occurs mostly in adults, but they can be present in infants, as well, as a result of congenital abnormalities or iatrogenic procedures (i.e. migration of naso gastric tube that placed before). We report a case of 10 days old full term, male neonate, was on naso gastric tube feeds, had clinical features of necrotizing enterocolitis (NEC), diagnosed to have gastrocolic ﬁstula on barium enema study and conﬁrmed on CT abdomen. Intraoperatively, baby had multiple perforations with gastrocolic ﬁstula. Histopathological examination was suggestive of NEC. We searched literature, we could ﬁnd seven case reports.

1. Case report A male neonate, born by full term emergency caesarian section to a primigravida mother for meconium stained amniotic ﬂuid, was limp at birth, had meconium aspiration syndrome and hence was referred to us for further management. Baby was small for gestational age with weight was 1980 g, Head circumference 34 cm, and total length at birth was 49 cm. Baby was ventilated for 3 days for moderate meconium aspiration syndrome. Trophic feeds via naso gastric tube were initiated on day 1 of life, baby reached full feeds (180 ml/kg/day, expressed breast milk) on day 6 of life. Baby was lethargic and hypotonic on day 5 of life. CRP was positive, hemogram, CSF and electrolytes were normal. In view of sepsis, antibiotics were started. On day 8 of life baby had increasing yellowish greenish aspirates suggestive of feeding intolerance. X ray abdomen was done was suggestive of dilated bowel loops, Necrotizing enterocolitis was suspected. Baby was kept NPO. In view of progressively increasing aspirates, Barium enema study was done on day 10 of life showed gastro colic ﬁstula (Fig. 1), was conﬁrmed on CT scan abdomen (Fig. 2). On day 11, exploratory laparatomy was

done. Baby had 5 intestinal perforations (Fig. 3) e intestinal resection and diversion was done. Histopathological examination of intestinal biopsy specimen showed mucosal edema, hemorrhage, necrosis suggestive of NEC. Baby was kept NPO for 5 days postoperative. On postoperative day 6, feeds were started. On day 21 of life, baby was on exclusive breast feeding, discharged on day 24 of life with discharge weight 1990 g. 2. Discussion In children, gastro colic ﬁstulae are very rare, especially in newborns and infants. Since 1945, only 8 cases have been reported in the literature . Gastro colic ﬁstulae result from perforation of the stomach into the colon or of the opposite, mostly among premature and immature small-for-dates infants . This occurs because of stress ulcer, gastric tissue ischemia or trauma, due to complications of necrotizing enterocolitis, Hirschsprung’s disease and meconium ileus, respectively. Also, gastro colic ﬁstulae in children can occur after migration or placement of PEG feeding tubes . Strictures complicating NEC occur in 20% of patients and usually involve colon . In contrast ﬁstula formation complicating NEC is rare and may occur with or without stricture. Clinical data on our one patient and the 8 previously described in literature are summarized in Table 1. The plain ﬁlm ﬁndings in the presence of ﬁstula are nonspeciﬁc. Clinically our patient presented with increasing aspirates without

abdominal distention and previously reported cases presented with diarrhea and abdominal distention. Clinical symptoms suggestive of feeding intolerance and nonspeciﬁc bowel gas pattern on plain x ray should raise the possibility of an existing ﬁstula. Several mechanisms may be proposed for the development of enterocolic ﬁstula following NEC. Severe colonic ischemia and subsequent bowel necrosis may develop over time inciting an inﬂammatory response. Continuous inﬂammation may result in adherence of affected segment of colon to adjacent bowel and eventual ﬁstulization. Alternatively, a sub acute perforation may be walled off by adjacent viscera resulting in ﬁstula formation. In cases mentioned in literature, time gap between diagnosis of NEC and ﬁstula formation was wide around 2 weekse10 weeks. However in our case it was early. In this case baby was IUGR, had suffered asphyxia and had MAS. This may have aggravated intestinal ischemia, leading to early postnatal ﬁstula formation. Alternatively as mentioned earlier sub acute perforation may be walled off by adjacent viscera resulting in ﬁstula formation. As mentioned in most of the reported cases, present case also did well postoperatively. Gastro colic ﬁstulae, a condition with poor prognosis, can arise from a variety of pathological processes, spontaneous or iatrogenic, and the classical symptoms are increasing aspirates, abdominal distention, vomiting and diarrhea. The best diagnostic method is

the barium enema, while other radiological methods play a signiﬁcant role to other parameters of the ﬁstulae. The therapy of this condition remains surgical. After all, we must emphasize that it is a serious pathologic condition that can lead to death.
