Thoracic epidural versus general anaesthesia for MRM surgeries.

Background: General anaesthesia is still the preferred technique amongst many practitioners for oncologic breast surgeries. However the TEA technique has a lot of advantages over the conventional GA technique. Objective: We attempted to evaluate the two techniques of anaesthesia for MRM surgeries. Materials and method: Sixty ASA I-II patients undergoing MRM were randomly assigned to two study groups of 30 patients each. In the TEA group( group T), an epidural catheter was inserted at T7-T8 level, and 8-10 ml of 0.5% bupivacaine was titrated and administered.GA (group G) was induced with 2mg/kg of propofol and was maintained with Isoflurane ,intermittent inj. Vecuronium and 70% N2O in oxygen. The authors evaluated the adequacy of anesthesia, surgical condition, post anesthetic recovery, post anesthetic analgesia and patients’ satisfaction. Results: The intra operative haemodynamics was comparable in between the two groups. The incidence of nausea and vomiting was significantly lower in the TEA group ( 16.5% in group T and 39.6% in group G , P = 0.02).The mean immediate VAS score was also lower in TEA group ( group T =2.4 , group G =5.8,P = 0.001).Aldrete recovery score was 9/10 in 1st hr in a significant proportion in the TEA group (89.1% in group T v/s 59.4% in group G , P = 0.003).Patient satisfaction was significantly higher. The surgeons were however satisfied with both the methods. Conclusion: Use of thoracic epidural technique as a sole anaesthetic technique for MRM surgeries provides adequate operating conditions, better side effect profile, better pain management and patient satisfaction.

Transjugular liver biopsy using Tru-cut biopsy needle: KEM experience.

BACKGROUND AND AIM: Transjugular liver biopsy is accepted procedure in patients in whom percutaneous liver biopsy is contraindicated. We report our experience with this procedure, its indications, efficacy and safety in Indian population over 5 years. MATERIAL & METHODS: A retrospective study of 145 consecutive patients who had undergone transjugular liver biopsy from May 2002 to Nov. 2007 was done from the database maintained in our department. We evaluated the indications, technical success, complication and impact of histological diagnosis on the management of those patients. RESULTS: 145 Transjugular liver biopsies were performed of which 74 were males and 71 were females aged between 5 and 74 years. Two procedures were abandoned due to failed hepatic vein cannulation because of venous occlusion. Out of 143 biopsies, 4 were inadequate while 139 yielded adequate tissue for histopathological diagnosis. Histopathological examination in our study showed cirrhotic changes in 56, hepatitis including both acute and chronic in 48, periportal fibrosis in 9, Wilson's disease in 5 and obstructive cholangiopathy in 2 patients. The remaining 19 were normal. Minor complications occurred in 2 patients. CONCLUSION: Transjugular liver biopsy is a safe procedure in the trained hands and provides adequate tissue for diagnosis when percutaneous liver biopsy is contraindicated.

Study of Takayasu's arteritis in children: clinical profile and management.

AIMS: To study clinical features, pattern of involvement and treatment modalities of Takayasu's arteritis (TA) in children. MATERIAL AND METHODS: Retrospective analysis of hospital records of children admitted over a period of 4.5 years. RESULTS: 17 patients in the age group of 5 to 11 years (M: F = 1.1: 1) were diagnosed to have TA on the basis of Ishikawa's criteria. One child was diagnosed post-mortem. The commonest presenting features were hypertension (64. 7%), congestive cardiac failure (47%), weak or absent peripheral pulses, cardiomyopathy (41.1% each) and cardiac valvular affection (35.2%). Retinopathy, hypertensive encephalopathy and abdominal bruits were uncommon. None presented in the prepulseless phase. No patient had an active tuberculous lesion, although Mantoux or BCG test was positive in 6 (35.2%). The predominant pattern of angiographic affection was Type II (52.9%). Nephrotic syndrome and portal cavernoma seen in one patient each were incidental associations. Anti-hypertensive drugs, oral steroids and drugs to control congestive heart failure were the mainstays of medical management. Antitubercular therapy was started in six patients. Angioplasty was attempted in 15 cases and proved to be partially beneficial in six. Three patients who failed to respond to medical management had to undergo surgical procedures, either bypass, nephrectomy or both. In-hospital mortality was 11.7%. CONCLUSIONS: Patients of TA in this study presented acutely in the pulseless phase, with hypertension and its complications. Type II involvement was the commonest pattern. Anti-hypertensive agents and steroids along with angioplasty were partially successful in controlling symptoms in 35.2%. Surgical procedures were reserved for a minority with poor response to drugs and angioplasty.

Pancreatic carcinoid: an unusual tumour in an uncommon location.

Primary pancreatic carcinoid is an extremely rare pancreatic neoplasm. It differs from other primary pancreatic tumours in cytoarchitecture, immunocytochemistry and biologic behaviour. Recognition of this rare entity is of vital importance having considerable therapeutic and prognostic implications. We report a case of an exophytic, pancreatic body carcinoid tumour in a man who presented with abdominal pain. The diagnosis was established by histopathological examination of the core biopsy specimen. A surgical resection of the lesion was done successfully and the patient made a satisfactory recovery from the operation.

Massive rectal bleeding due to jejunal and colonic tuberculosis.

A case of massive rectal bleeding due to colonic tuberculosis in advanced pregnancy with intrauterine foetal death is reported. Patient was treated with resection of the left colon and left transverse end colostomy with closure of the rectal stump. Hysterotomy for the removal of the dead foetus was performed. The patient improved in health with antitubercular treatment. The colorectal anastomosis was performed after 4 months. Massive rectal bleeding in intestinal tuberculosis, though rare should be kept in mind.

Jejunal angiomatoses causing small bowel obstruction in a patient with Down syndrome: a case report.

Gastrointestinal vascular anomalies are extremely uncommon. We describe a patient with Down syndrome who presented with acute abdominal pain due to a mixed capillary and venous vascular malformation involving the proximal jejunum.

A giant vascular hamartoma of the breast in a child.

Vascular tumors of the breast are uncommon. Perilobular hemangiomas, the commonest histologic subtype of breast hemangiomas, constitute majority of microscopic, vascular mammary tumors. Macroscopic hemangiomas and vascular hamartomas of the breast are distinctly rare. We describe a giant, vascular hamartoma of the right breast in a five year old girl and discuss pertinent literature.

Chylothorax--a conservative approach (a case report).

Lymphatic blockage due to a non-specific inflammation probably of a filarial origin caused dilatation and ectasia of lymph channels at thoracic inlet of a child. Transudation of lymph through these channels led to chylothorax. The present case report highlights the significance of conservative approach towards this complex problem.

Obstructive jaundice--an unusual complication of duodenal tuberculosis: treatment with transhepatic balloon dilatation.

This is a report of a patient on treatment for duodenal tuberculosis, who developed obstructive jaundice due to a benign stricture of the terminal common bile duct. This complication of duodenal tuberculosis, to our knowledge, has not been reported before. Percutaneous, transhepatic balloon dilatation of the stricture alleviated the jaundice.

Diagnosis of venous disorders using impedance plethysmography.

Impedance plethysmography (IPG) was carried out in one hundred and forty-one patients suspected of venous disorders using Parulkar's method. In these patients occlusive impedance phlebography (OIP) and venography were also carried out using standard procedures. Comparison of IPG and OIP observations with venographic findings revealed sensitivity of these methods to be 65% and 77.7% in the diagnosis of primary varicosity of veins and chronic deep vein thrombosis respectively with a specificity of 85%. Occlusive impedance phlebograms showing unilateral decrease in OIP parameters were observed to be sufficiently diagnostic. IPG observations in 5 patients with arterio-venous malformation were observed to be different from those in patients with deep vein thrombosis.

Impedance plethysmographic observations in thoracic outlet syndrome.

Forty patients with symptoms of neuro-vascular compression in the upper extremities were subjected to impedance plethysmographic study using Parulkar's method. Two patients recorded decreased blood flow (BFI) in supine position and were diagnosed as having partial occlusion at subclavian level. Sixteen of the patients recorded decreased BFI on 90 degrees abduction and hyper-abduction. Twelve of these patients had radiological evidence of anomalous cervicle ribs. In remaining four patients extrinsic impression on the subclavian artery due to fibrous deposits was confirmed by arteriography. Remaining 22 patients recorded normal impedance plethysmograms. Impedance plethysmography thus provided a non-invasive modality for confirmation of vascular compression in thoracic outlet syndrome.

Effect of sublingual isosorbide dinitrate in portal hypertension.

Nitrates decrease portal pressure by decreasing portal venous inflow and resistance. We studied over 20 minutes the effect of 10 mg isosorbide dinitrate sublingual on intrasplenic pulp pressure, mean arterial pressure and heart rate, in 13 patients with cirrhotic or non-cirrhotic portal hypertension. The pulp pressure fell progressively over 20 minutes, from mean 43.6 +/- 2.4 (SEM) to 35.6 +/- 1.8 cm H2O (p less than 0.001). This was accompanied initially by a significant fall in mean arterial pressure (85.8 +/- 1.9 to 80.4 +/- 2.7 mmHg at 4 minutes; p less than 0.01) and rise in heart rate (92.5 +/- 5.0 to 102.6 +/- 5.9 per minute at 6 minutes; p less than 0.02), following which these parameters remained stable. One patient developed giddiness due to hypotension at 15 minutes. We conclude that sublingual isosorbide dinitrate decreases pulp pressure in cirrhotic and non-cirrhotic portal hypertensives, but this is initially accompanied by significant hemodynamic changes.

Endoscopic removal of retained bile duct calculi via T-tube tract.

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.
