A randomized double-blind controlled trial comparing two forms of enema for flexible sigmoidoscopy.

OBJECTIVE: To compare bowel preparation quality and patient tolerance of two common enema solutions for flexible sigmoidoscopy. MATERIAL AND METHOD: Three hundred adults were randomized to receive a hypertonic sodium chloride or hypertonic sodium phosphate enema regime, each consisting of two enemas administered 60 and 30 min before the procedure. Patients completed surveys on preparation comfort. Patients and endoscopist were blinded to the preparation used During the procedure, the endoscopist took pictures of the mucosa and intraluminal content. All pictures were later evaluated by a single doctor who graded the quality of the preparation. RESULTS: There were no serious complications during or following the procedures. The preparation quality was rated as excellent or good by 76.9% of the hypertonic sodium chloride group and 72.9% of the hypertonic sodium phosphate group (p = 0.423). The hypertonic sodium chloride enema was associated with more abdominal discomfort (p = 0.018). CONCLUSION: Both enemas were safe for all patients with no statistical difference between the qualities of the two bowel preparations. Both preparations performed their bowel-cleaning function well and were suitable for the preparation of patients before flexible sigmoidoscopy. The less expensive hypertonic sodium chloride solution may be an option for hospitals where budgetary considerations are important.

Circumumbilicus incision for bleeding Meckel's diverticulectomy.

BACKGROUND/OBJECTIVE: With regard to the recent interest in minimally invasive surgery, the authors report on a technique of transumbilical incision for Meckel s diverticulum and appendectomy, which provides better cosmetic results and no increase in complications. MATERIAL AND METHOD: The case records of 18 consecutive Meckel's diverticulum (MD) patients who were treated at Songklanagarind Hospital in Thailand between 1996 and 2005 were reviewed. RESULTS: The male-female ratio was 14-4 (3.5:1). Of the 15/18 (83.3%) symptomatic cases, presenting symptoms were bleeding 10/15 (66.7%), gut obstruction 2/15 (13.3%), peritonitis 2/15 (13.3%), and intussusception 1/15 (6.7%). All bleeding patients were children (age 1-15 years), 9/10 (90%) Meckel scan positive and 10/10 (100%) ectopic-gastic tissue. Four children underwent a circumumbilical incision. There were no perioperative or long-term complications related to the transumbilical approach. CONCLUSION: The umbilical incision has all the benefits of a minimal access approach. Umbilical incision is a safe, inexpensive, cosmetically pleasing, and easy technique. This minimally invasive surgery does not require long-term specialized training or special equipment.

When should MRI be recommended for the accurate clinical staging of base of tongue carcinoma?

BACKGROUND AND PURPOSE: According to the American Joint Committee on Cancer (AJCC) cancer staging criteria (6th edition), cross-sectional imaging for base of tongue carcinoma is recommended when the deep tissue extent of a primary tumor is in question. The aim of this study was to establish which group of patients MRI might most benefit from accurate clinical staging of base of tongue carcinomas. PATIENTS AND METHODS: The clinical stagings of 33 patients with pathologically proven squamous cell carcinomas of the base of tongue were performed by two otorhinolaryngologic surgeons. Their results were compared with the results from MRI interpreted by a neuroradiologist and the numbers of patients being upstaged, downstaged or with an unchanged stage were recorded and analyzed. RESULTS: The tumor stages were changed in 13 of 33 patients (39.4%, 95% CI: 23.9-57.87%) and the overall stage groupings were changed in 10 (30.3 %, 95%CI: 15.6-48.7%) after performing MRI. Mis-staging by clinical examination in the overall stage grouping was as high as 83.3% (95%CI: 35.9-99.6%) in stages II and III and 85.7% (95% CI: 42.1-99.6%) in T3. CONCLUSION: MRI should be recommended in base of tongue carcinoma whenever clinical examination suggests overall stage groupings II, III or tumor stage T3.

Repair of extra-cranial internal carotid artery aneurysm with application of modified carotid shunt: a case report.

Aneurysms of the extracranial internal carotid artery (ICA) are uncommon. These lesions usually present with symptoms of transient ischemic attacks (TIA) from emboli and cranial nerve dysfunction from compression. The primary objective of treatment is to prevent a permanent neurologic deficit arising as a result of atheroembolism. The resection of an ICA aneurysm with restoration of flow is the preferred method of treatment. The authors present the case of a 32-year-old woman diagnosed with an ICA aneurysm. The patient underwent aneurysmectomy using an autologous saphenous vein graft with ICA blood flow being maintained using a carotid-to-carotid shunt, which was modifiedfrom an intravenous catheter set. This modified carotid shunt is easy to prepare for use and is of low cost. The authors do not expect this shunt to represent the standard commercially available shunt; but in some institutes, where commercial shunts are not available, this shunt may be suitably used.
