Distribution patterns of transforaminal injections in the cervical spine evaluated by multi-slice computed tomography 总被引:1,自引:1,他引:0
Transforaminal injections are sometimes used for the diagnosis and treatment of painful conditions in the lumbar and to a lesser degree in the cervical spine. The technique is most often used when investigating/treating radiculopathy caused by degenerative disease. But how selective are the nerve root blocks? What possible structures other than the intended nerve root are affected from such injections? This study was undertaken in order to try to answer these questions, as no study focusing on the possible spread from the transforaminal selective nerve root blocks in the cervical spine has been performed earlier. In three groups of patients, each group including three patients, we injected three different volumes (0.6, 1.1 and 1.7 ml) with a transforaminal technique in the cervical spine. In all the injections, a small amount of contrast media was added. The spread of the injections were then investigated using multi-slice computed tomography with reconstructions. The imaging revealed a possible effect on other nerve roots than the intended ones when a larger volume was used for the root blocks. The spread was related to the injected volume as well as to local anatomy (size of foraminal area). In this study, only 0.6-ml injections could be accepted for being selective enough for diagnostic investigations. 相似文献

Parastomal hernia in relation to site of the abdominal stoma 总被引:13,自引:0,他引:13
Parastomal hernia is a common late complication of enterostomy, especially colostomy, and sometimes requires surgical treatment. A possible contributory factor, location of the stoma in relation to the rectus abdominis muscle, was studied by examination of 130 patients with permanent intestinal stoma. The bowel had been brought out through the rectus abdominis muscle in 107 patients and lateral to it in 23 patients. The respective prevalence of parastomal hernia in these groups was 2.8 per cent and 21.6 per cent. The highly significant difference indicates that enterostomy should be constructed through the rectus abdominis muscle, not lateral to it. 相似文献

The dissolution rates of sparingly soluble, fine particulate, suspended drugs have been studied using a Coulter Counter Model TAII. For two sieve fractions of oxazepam the dissolution rates were monitored in media with varying viscosities brought about by the addition of glycerol, while for griseofulvin the change in the medium's viscosity was induced by changing the temperature. By calculating the dissolution rate, and compensating for differences in particle surface area and media solubility, it was shown that the dissolution rate was diffusion controlled. After additional normalization for the diffusion coefficient, it was suggested that the so-called apparent diffusional distance decreased substantially with particle size. The effect of particle size was more limited above approx. 15 μm. 相似文献

BACKGROUND: A prospective randomized multicentre study was performed to compare the outcome of laparoscopic and open appendicectomy in patients with suspected acute appendicitis. METHODS: A total of 523 patients was randomized, but because of 23 withdrawals the outcome in 500 patients is reported, 244 in the laparoscopic group and 256 in the open group. RESULTS: Patients having laparoscopic appendicectomy recovered more quickly than those having open surgery (13 versus 21 days, P < 0.001). There was no significant difference in duration of sick leave after operation (laparoscopic group 11 days versus open group 14 days). Postoperative pain (at 24 h, 7 days and 14 days) was less after laparoscopic operations and a functional index 1 week after operation was more favourable in these patients (P < 0.001). Operating time was significantly longer in the laparoscopic group (60 versus 35 min, P < 0.01). Hospital stay and complications did not differ between the groups. Thirty laparoscopic procedures (12 per cent) were converted to open appendicectomy. CONCLUSION: Laparoscopic appendicectomy is as safe as open appendicectomy and has the advantage of allowing a quicker recovery. 相似文献

OBJECTIVE: No long-term studies of laparoscopic and open fundoplication were available in 1994. The aim of this study was to compare reflux control and side effects after laparoscopic and open fundoplication. MATERIAL AND METHODS: Adult patients with uncomplicated gastro-oesophageal reflux disease were included in this prospective randomized clinical trial between laparoscopic and open 360-degree fundoplication. Patients with uncomplicated gastro-oesophageal reflux disease were included with the exception of those with weak peristalsis or suspected short oesophagus. Two senior surgeons, well trained in laparoscopic antireflux surgery, performed the 45 laparoscopic operations. Forty-eight patients underwent open surgery performed or supervised by two other senior surgeons, also well trained in gastro-oesophageal surgery. One of the latter recruited all the patients. Manometry and 24-h oesophageal pH monitoring were performed before operation and 6 months postoperatively. Manometry also included a short-term reflux test, an acid clearing test and an acid perfusion test. Symptom evaluation was performed before surgery, 6 months after and at long-term follow-up (33-79 months postoperatively) by the same surgeon. Long-term follow-up also included endoscopy. RESULTS: Six months after laparoscopy 4 patients had disabling dysphagia. None of the patient had disabling dysphagia after laparotomy. Four patients had mild heartburn 6 months after laparoscopy and 2 patients after laparotomy. Between 6 months' follow-up and long-term follow-up, 6 patients were reoperated on in the laparoscopy group and 2 patients in the laparotomy group. Three patients operated on with laparotomy had died of intercurrent diseases. After laparoscopy, at long-term follow-up, 62% of patients (28/45) were satisfied compared with 91% (41/45) after laparotomy. The difference was significant (p<0.01). CONCLUSIONS: Early postoperative reflux control was similar for laparoscopic and conventional fundoplication. At long-term follow-up significantly more patients were satisfied after laparotomy than after laparoscopy. 相似文献

Background
Postoperative bowel obstruction caused by intra-abdominal adhesions occurs after all types of abdominal surgery. It has been suggested that the laparoscopic technique should reduce the risk for adhesion formation and thus for postoperative bowel obstruction. This study was designed to compare the incidence of bowel obstruction in a randomized trial where laparoscopic and open resection for colon cancer was compared.Methods
A retrospective analysis was performed, collecting data of episodes of bowel obstruction with or without surgery. Only episodes treated in the hospital where the index surgery took place were included. Data for 786 patients were collected for the 5-year period after cancer surgery.Results
Baseline characteristics for the evaluated laparoscopic (n?=?383) and open (n?=?403) groups were comparable. The cumulative obstruction percentages at 5?years for the open and laparoscopic groups were 6.5 and 5.1% respectively and did not significantly differ from each other. Tumor stage seemed to influence the risk for bowel obstruction: 2.8% in stage I, 6.6% in stage II, and 7% in stage III, but the differences were not significant.Conclusions
This analysis does not support the hypothesis that laparoscopy leads to fewer episodes of bowel obstruction compared with open surgery. 相似文献9.

Objective The colon cancer laparoscopic or open resection (COLOR) trial is an international, randomised controlled trial comparing outcomes
of open and laparoscopic surgery for colon cancer. The main purpose of this study was to determine representability by comparing
included and nonincluded patients in the participating Swedish centres.
Design At eight centres, which included 391 of the 422 Swedish patients, a local database search was performed to identify retrospectively
all patients (n = 2,384) who underwent surgery for colon cancer during the inclusion period, and data was retrieved from medical records.
Results Four hundred fifty-six patients were randomised, 65 of whom were excluded post randomisation (group 2), leaving 391 patients
in the study (group 1). For 1,566 patients, valid exclusion criteria were found (group 3). Thus, 362 patients were eligible
but not included (group 4). Relative to group 1, patients in group 4 had a significantly higher American Society of Anaesthesiologists
(ASA) score, more advanced tumour stage and difference regarding the resections performed. Results showed that 1470 patients
(62%) could be calculated as feasible for laparoscopic colon resection (LCR) in a clinical, nontrial situation.
Conclusions The study population in the Swedish part of the COLOR trial was representative of the eligible population with the exception
of comorbidity, where those actually included had less severe comorbidity than the nonincluded but eligible patients. In Sweden,
50–60% of colon cancer patients can be operated on by laparoscopy.

Elderly persons' experiences of striving to receive care on their own terms in nursing homes
Elderly persons' participation in and decisions about their own care need more attention. The aim of this study was to gain a deeper understanding of elderly persons' experiences of care and help, and how their lives change in nursing homes. Fifteen elderly persons living in four nursing homes were interviewed about their experiences of needing care and help in their daily life. The interviews were analysed using van Manen's phenomenological approach. Elderly persons' experiences of care and help were described as: a balance between sorrow and relief, a struggle to maintain control and connectedness, managing to live in the present and yet worrying about the future, and an attempt to hide one's vulnerability in order to be accepted and create an inner calm in an exposed situation. In conclusion, important issues were raised concerning elderly persons' perspectives on care and help in daily life in nursing homes. 相似文献
