1/4. Intra-operative and post-operative hypercapnia leading to delayed respiratory failure associated with transanal endoscopic microsurgery under general anaesthesia.We present an unusual case of hypercapnia and surgical emphysema during transanal endoscopic microsurgery, which led to delayed post-operative ventilatory failure. The hypercapnia and surgical emphysema were secondary to rectal insufflation with carbon dioxide used to facilitate visualization and resection of a rectal tumour. Despite a return to wakefulness after surgery, the patient's level of consciousness deteriorated in the recovery area as a result of hypercapnia. The PaCO2 rose to 16.8 kPa because of absorption of carbon dioxide from the surgical emphysema. On close examination, surgical emphysema was identified in unusual areas, including the anterior abdominal wall, both loins, both groins and the left thigh. Reventilation was required until these unusual carbon dioxide stores had dissipated. We discuss the need for prolonged post-operative vigilance in patients with surgical emphysema secondary to carbon dioxide insufflation, and the risk of delayed ventilatory failure.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/4. Management of the pelvic recurrence of rectal cancer with radiofrequency thermoablation: a case report and review of the literature.INTRODUCTION: The results of rectal cancer surgery are limited by the development of local recurrence (LR) that represents a great challenge to the surgeon. In the presence of unfavourable conditions for performing a curative operation, various forms of palliative treatment are indicated to control the patient's symptoms and the disease's complications. Recently, radiofrequency thermoablation (RFTA) has become a complimentary alternative therapy for malignant inoperable liver tumours. The present paper reports the use of RFTA in the management of pelvic recurrence of rectal adenocarcinoma. CASE REPORT: Fourteen months after abdominoperineal resection, a 32-year-old woman began to complain of progressive pelvic and lumbar pain. A large pelvic mass was found and serum CEA was elevated (66.4 ng/ml) at that time. Due to the dimensions of the presacral tumour (8 x 5 x 4 cm3) and the associated refractory pain, the patient underwent RFTA of the recurrent disease. Under epidural anaesthesia, a computed tomography-guided percutaneous needle electrode was introduced into the tumour. Although the procedure provided immediate pain control, the patient developed an intestinal obstruction 3 months later. This complication required surgical treatment to release adherences from the necrosed tumour. CONCLUSION: Apart from this complication, RFTA allowed prolonged relief of the pelvic pain and improved quality of life. Faced with an unresectable pelvic recurrence, RFTA proved to be a viable option for controlling pain, although a relatively high cost and eventual complications may limit its use.- - - - - - - - - - ranking = 0.25keywords = anaesthesia (Clic here for more details about this article) |
3/4. Development of adenocarcinoma in chronic fistula in Crohn's disease.The authors report the case of a 55 yr-old woman suffering from Crohn's disease since 31 years with stricture and fistulas developed in the ileocolic junction and anorectal portion. Long-standing anorectal fistulas and stricture led to adenocarcinoma and finally fistulisation in the vagina. diagnosis was made by perineal examination with biopsies under general anaesthesia. Treatment was first posterior pelvectomy with resection of the anterior wall of vagina. Secondarily, radiochemotherapy was administrated. The authors discuss the incidence and risk factors of carcinoma in Crohn's disease with chronic fistulas.- - - - - - - - - - ranking = 0.25keywords = anaesthesia (Clic here for more details about this article) |
4/4. Use of continuous positive airway pressure during spinal anaesthesia in a patient with severe chronic obstructive pulmonary disease.We report the case of a patient with severe chronic obstructive pulmonary disease who underwent local resection of a carcinoma of the rectum under spinal anaesthesia. Although the patient was keen to avoid general anaesthesia and to have the operation under a spinal anaesthetic, pre-operative assessment showed that he could not lie flat. As the surgical procedure required the patient to be in the lithotomy position, ideally with a head-down tilt, it was hoped that continuous positive airway pressure with a facemask during spinal anaesthesia might help him to tolerate the position comfortably. continuous positive airway pressure at 7.5 cmH(2)O was successfully used to facilitate breathing during surgery under spinal anaesthesia. A combination of regional anaesthesia and continuous positive airway pressure via a facemask is easy to use and may be a useful option in the management of these challenging patients.- - - - - - - - - - ranking = 2.25keywords = anaesthesia (Clic here for more details about this article) |
