Achalasia cardia with esophageal varix managed with endoscopic ultrasound-guided botulinum toxin injection.

Achalasia cardia is a motility disorder of the esophagus characterized by failure of relaxation of the lower esophageal sphincter. Nitrates and calcium channel blockers, pneumatic dilatation, botulinum toxin injection and surgical myotomy have been described in literature as possible management options. We present a patient who presented with achalasia and was co-incidentally diagnosed to have cryptogenic cirrhosis with portal hypertension and had esophageal varices. This clinical combination precluded the use of pneumatic dilatation and surgical myotomy.We injected botulinum toxin into the lower esophageal sphincter using a celiac plexus neurolysis needle under endoscopic ultrasound guidance; the clinical response was good.

Extracorporeal shock wave lithotripsy and endotherapy for pancreatic calculi—a large single center experience.

Aim Large pancreatic ductal calculi and pain are a feature of chronic calcific pancreatitis (CCP) in the tropics. This large single center study evaluates the role of extracorporeal shock wave lithotripsy (ESWL) in fragmentation of large pancreatic stones and relief of pain in patients with CCP. Methods Patients with CCP presenting with pain and large pancreatic duct (PD) calculi (>5 mm diameter) not amenable to extraction at routine endoscopic retrograde cholangio pancreatography (ERCP) were taken up for ESWL using a 3rd generation lithotripter. Stones in the head and body of pancreas were targeted at ESWL; 5,000 shocks were given per session. The calculi were fragmented to <3 mm size and then cleared by endotherapy. Pancreatic duct stents were deployed when indicated. A total of 1,006 patients underwent ESWL. Complete clearance was achieved in 762 (76%), partial clearance in 173 (17%) and unsuccessful in the rest. More than 962 (90%) of patients needed less than three sessions of ESWL. At 6 months, 711 (84%) of 846 patients who returned for follow up had significant relief of pain with a decrease in analgesic use. Complications were mild and minimal. Conclusion ESWL is an effective and safe modality for fragmentation of large PD calculi in patients with CCP.

Absence of Mycobacterium avium ss paratuberculosis-specific IS900 sequence in intestinal biopsy tissues of Indian patients with Crohn’s disease.

Background and Objective The role of Mycobacterium avium ss paratuberculosis (MAP) in the etiopathology of Crohn’s disease (CD) remains controversial, because of conflicting reports demonstrating the presence of MAP-specific insertion sequence from intestinal biopsy tissues of patients clinically diagnosed for the disease. The present study was carried out to investigate the presence of MAP DNA in the intestinal tissues of CD patients to ascertain the relevance of MAP in Indian patients with CD. Methods Patients diagnosed as CD at our institute were recruited. Healthy individuals without inflammatory bowel disease served as controls. Mucosal biopsy specimens were collected from ileum and colon in duplicates and subjected to histopathological examination and polymerase chain reaction (PCR) amplification. Total DNA (81 CD patients, 85 healthy individuals) and total RNA (12 CD patients, 12 healthy individuals) isolated from tissue specimens was used for amplification of MAP-specific IS900 by nested PCR. Results MAP-specific IS900 DNA and RNA could not be detected by nested PCR in the intestinal tissues of any patient with CD. Conclusion Our results do not support the etiological role of MAP in the pathogenesis of CD in Indian patients.
