A case of late progressive myelo-radiculopathy associated with severe canal stenosis secondary to post-traumatic hypertrophy of thoracic laminae and ossification of spinal ligaments viz. ligamentum flavum and posterior longitudinal ligament in the absence of developmental spinal stenosis or post-traumatic deformity, is presented with a brief critical review of the relevant literature.
Pneumatic dilatation is one of the more recent methods in the management of achalasia cardia. Fifty dilatations were done in 42 patients with achalasia cardia over 5 years. There was a significant decrease in the maximum diameter of the oesophagus and a significant increase in diameter in the narrowed lower oesophageal segment in all the patients. Of the patients studied, 95.23% were relieved of their symptoms after only one to two sessions. There were no immediate complications. Out of the 38 patients on long term follow up, 8 (21.05%) had recurrence of symptoms. On repeat dilatations, 4 (50%) of them had good response. Late complication like reflux oesophagitis was observed in only 1 patient over a median follow up period of 22 months. It was thus concluded that pneumatic dilatation is a safe, simple and effective procedure in managing patients with achalasia cardia.
Pneumoretroperitoneum and pneumomediastinum are rare complications of laparoscopy. We report one such case. The mechanism of development of these complications is explained. No specific treatment needs to be instituted in most of these patients.
Twenty-five cases with ischemic bowel disease seen over a period of 4 years are presented. Of these, 20 cases presented with acute symptoms and five with chronic symptoms. In the majority of patients, the diagnosis was established at operation and on histopathology. Occlusive disease of the superior mesenteric artery was the commonest cause of acute ischemia. Non-occlusive ischemia was not observed in any case. All the patients were treated by resection and anastomosis of the involved bowel. Vascular procedures were not carried out in any. No planned second-look procedures were carried out. Of the 20 acute cases, eight patients died and three developed complications. One chronic case died and there were no other complications in this group. We suggest that ischemic bowel disease should be considered while dealing with cases presenting as acute abdomen or with chronic abdominal pain.

A simple and safe technique for removal of retained bile duct calculi using a flexible fibreoptic choledochoscope and rigid nephroscope via the T-tube tract has been described. The technique allowed removal of large impacted calculi under direct vision without damage to the bile duct.
Torrential hemorrhage is rare in tuberculous affection of the bowel. The traditional method of treatment has been immediate surgical intervention aimed at bowel resection. To our knowledge, this is the first report of successful control of such life-threatening hemorrhage by transcatheter embolisation.
Three patients (average age 61 years) presenting with retrosternal pain were evaluated with barium studies of the upper gastrointestinal tract. In each case, the esophagus was significantly displaced by a tortuous aorta. All patients had sliding hiatal hernias; these hiatal hernias, and the esophagitis and disordered motility seen in our patients, could be a consequence of esophageal displacement by the tortuous aorta. Two patients were relieved symptomatically with antacids and metoclopramide. Thus, tortuosity of the thoracic aorta can cause esophageal chest pain.
A 35 year old man presented with massive lower gastrointestinal hemorrhage due to typhoid enteritis. After confirming the site of bleeding on a selective superior mesenteric angiogram, a vasopressin infusion was given at the rate of 0.2-0.4 units/min initially, followed by tapering doses over 36 hours. Cessation of bleeding was achieved immediately. The patients did not have any complications due to the procedure. Continuous vasopressin infusion is an effective method for the treatment of uncontrolled bleeding from typhoid enteritis.

Lipomas of the anterior neck are rare lesions with about 40 cases reported so far in the world literature. Though lipomas are known to change shape depending upon adjacent compressive forces, our case is unique in that the change in shape clinically mimicked an external laryngocoele. A possible explanation for the unusual behaviour of this lipoma is offered.
We report a case of fatal rupture of a false aneurysm of the ascending aorta during aortographic injection. The aneurysm had formed at the site of aortic cannulation done for a cardiac bypass at an earlier date. The rupture manifested as hemoptysis as the false aneurysm had burrowed and ruptured into the anterior segment of the right upper lobe of the lung.

We have successfully deflated "obstinate" Foley's urinary catheter balloons in 15 cases in the last six months with the help of a simple bedside procedure using an angiographic guide-wire.
