RESUMEN
Despite various theories to explain the pathogenesis of atresias, the exact mechanism is still controversial. Currently, atresias are believed to result from vascular accidents and less likely due to the failure of recanalization. We report a case which challenges this belief. A 1-day-old neonate was explored for suspected jejunal atresia. Apart from Type III jejunal atresia, 15 cm from DJ junction, there was surprisingly no distal lumen in the intestine from jejunum till rectum. Multiple enterotomies revealed the whole of the remaining jejunum, ileum, and large colon to be a solid cord-like structure. No distal luminal contents or histopathological evidence of ischemic damage was seen, thus suggesting the probable etiology to be a failure of recanalization of the gut cord rather than a late vascular accident. Such rare cases provide insights into possible embryogenetic mechanisms which can then aid in formulating preventive measures.
RESUMEN
AIMS: The aim was to compare biliary amylase, common channel, and gall bladder/liver histopathology between spherical and fusiform choledochal cysts. MATERIALS AND METHODS: Children undergoing cyst excision with Roux-en-Y hepatico-jejunostomy over a 17 months period were prospectively studied. The common channel was assessed by three-dimensional (3D) magnetic resonance cholangiopancreatography (MRCP). RESULTS: Among 22 patients (spherical = 10, fusiform = 12), there was a higher incidence of spherical cysts in infants (5/7-71.4%) and fusiform cysts in older children (10/15-66.7%) (P = 0.09). Common channel identified in 14 (64%) cases was long (>10 mm) in 5 (38.2%) (one spherical, four fusiform [P = 0.5]) with associated high biliary amylase levels (>500 IU/L) in four (one spherical, three fusiform) (P = 0.05). Exact point of junction of common bile duct with pancreatic duct was visible with coronal half-Fourier-acquisition single-shot turbo spin-echo and 3D sampling perfection with application with optimize contrast using different flip angle evolution sequence using a reformatted plane of axis, particularly coronal, and coronal oblique orientation. Biliary amylase was raised (>100 IU/L) in 4 (40%) in the spherical group, compared to 8 (67%) in the fusiform group. Mean biliary amylase was similar in gallbladder and cyst in spherical but higher in gallbladder in fusiform cysts. Mean biliary amylase was <500 IU/L in 85.7% infants. Five out of 7 infants had liver fibrosis or cirrhosis on histopathology (P = 0.05). There were no dysplastic changes in the gallbladder epithelium. CONCLUSION: Three-dimensional MRCP delineated the common channel in two-third cases especially in coronal and coronal oblique orientation. The long common channel may have an etiological role in fusiform cysts. Spherical cysts, especially in infants, have a higher incidence of obstructive cholangiopathy.
RESUMEN
The appropriate pain management in neonates and children is lacking. Factors that prevent the execution of proper pain relief vary from center to center. We studied the factors responsible for it in a surgical unit. We conducted a survey at a tertiary-level institute among the resident doctors and nursing staff by means of an informal questionnaire analyzing their basic knowledge. The questions pertained mainly to pain assessment, analgesic usage, role of opioids, and formal training, and the responses so obtained were analyzed under these four headings. Seventy-three percent (22/30) of the residents and 74% (26/35) of the nursing staff knew about pain assessment scoring system in pediatric patients. However, assessment of pain in emergency cases was always done by only 6.6% of the residents. Effect of analgesia on severity of pain was never recorded by 33% (10/30) of the residents. Eighty-six percent (26/30) of the residents and 91% (32/35) of the nursing staff had adequate knowledge about analgesic dosage and interval for routine use. Ten of the 30 (33%) residents believed that analgesic administration in an acute abdomen, before definitive diagnosis, will always mask the symptoms. During a minor procedure, 56% (17/30) of the residents always used analgesia. Only 3.3% (1/30) of residents and 2.8% (1/35) of the nursing staff had received a structured training for pain management. Although, 93% (28/30) of the residents claimed to know about the safety of use of opioids, only 46% (14/30) used them routinely as analgesics. Pain management in surgical neonates and children is often ignored. Lack of formal training, inadequate knowledge, and standard protocols are the barriers in our setup, which may in turn be due to overwhelming attention given to the surgical condition.
