Background: Small bowel obstruction is common in clinical practice and is most often due to adhesions. The aim of this study was to determine the significance of colon cancer presenting as a small bowel obstruction at a single institution and to find out whether routine colonoscopy was necessary in patients who had spontaneous resolution of their small bowel obstruction. Methods: A retrospective review of the medical records of patients presenting with small bowel obstruction from 1995 to 2000 at the Prince of Wales Hospital was performed. The clinical outcomes were obtained from the medical records and the clinical notes of each surgical consultant. Results: Over the study period, 251 patients presented with small bowel obstruction. The mean age at presentation was 63.8 years (range 21?95 years). A total of 149 patients (59.4%) were treated conservatively with an average hospital stay of 4.6 days (range 1?20 days). Another 100 patients (39.8%) were treated operatively with a mean time from presentation to operation of 2.2 days (range <24 h?14 days). The remaining two patients (0.8%) were managed palliatively because of known metastatic disease. At laparotomy, 13 patients (13%) had a colon cancer identified. A further three patients were identified to have a colon cancer on follow up colonoscopy. However, only one of the three patients had had a previous laparotomy, that is, only 0.7% (1/149) of patients with a spontaneously resolved small bowel obstruction (presumably secondary to adhesions) had actually had colon cancer. Conclusions: The overall incidence of small bowel obstruction secondary to colon cancer is significant at 6.4%. However, as the incidence of colon cancer in patients who had had a previous laparotomy and spontaneous resolution of their obstruction was very low at 0.7%, routine colonoscopy does not seem warranted. 相似文献

OBJECTIVE: Primary cardiac tumours are rare. The literature predominantly contains series on myxomas in adults and only a few long-term series that involve the very different primary cardiac tumours in early childhood. As foetal ultrasonography has continued to improve, cardiac tumours are increasingly detected early before significant symptoms develop. It is a challenge for paediatric cardiologists and surgeons to ascertain which patients need surgery and which will benefit from conservative follow-up. METHODS: A retrospective review of a 10-year period revealed 51 tumours in 26 children (median age: 1 month). Analysis was by presentation, location, associated findings, interventions, histological findings, and clinical course. RESULTS: The most common tumours were rhabdomyomas (29), fibromas (nine), teratomas (two), and haemangiomas (two). The tumour location was the right ventricle in 24 and the left ventricle in 22 patients. The symptoms varied between abnormal heart murmur (20), arrhythmia and conduction abnormalities (ten), obstruction of the outflow tract >30 mmHg (nine), severe cyanosis (three) and congestive heart failure (two). Fourteen children with haemodynamic compromises underwent surgery. There was one post-operative death and one heart transplantation after bridging with an assist device. There was no tumour recurrence even when resection was incomplete. Nine of 13 children with rhabdomyomas had spontaneous tumour regression without intervention. CONCLUSIONS: Most of the cardiac tumours in children are benign. Spontaneous regression is possible not only in rhabdomyoma. Surgical intervention is only required for children who develop relevant clinical symptoms. Total resection of the tumour is not the only therapeutic aim; more important is the restoration of the best possible heart function. 相似文献

Small bowel intussusception in adults is a rare surgical disease which almost always occurs as a complication of either benign or malignant lesion of the bowel that is working as a leading point. In adults, the surgical approach consists of the resection of the bowel involved to ensure the excision of the lesion below. The authors report a case of ileocecal intussusception occurred in a young woman, 35 years old, observed for abdominal pain and signs of small bowel occlusion. She underwent surgical resection of the ileocecal segment with laparoscopic approach. The authors discuss the feasibility of the laparoscopic approach in this rare surgical disease and its benefits in terms of patient's postoperative comfort and outcome. 相似文献

OBJECTIVE: To evaluate the necessity of abdominal screening beyond physical examination in awake and alert blunt trauma patients who require emergent extra-abdominal trauma surgery. METHODS: Data from an urban Level I trauma center was reviewed for all blunt trauma patients who underwent extra-abdominal emergency procedures during the period from January 1995 through August 1998. Awake and alert patients (Glasgow Coma Scale [GCS] score > or = 14) with negative abdominal physical examination results who underwent extra-abdominal emergent surgery were entered in the study. All patients entered were older than 14 years of age, hemodynamically stable, and underwent further abdominal evaluation with computed tomographic scan or diagnostic peritoneal lavage after the decision for extra-abdominal surgical intervention. Emergent surgery occurred within 8 hours of admission. Data was collected for results of diagnostic studies, hemodynamic status, mechanism of injury, indications for operative intervention, and admission blood ethanol (EtOH) levels. RESULTS: A total of 210 patients with an average age of 33 years (range, 14-92 years) were entered in the study. The most common mechanism of injury was motor vehicle crash (67%). Sixty-six (32%) patients presented with EtOH levels > 100 mg/dL; 181 (86%) patients presented with a GCS score of 15, and 29 (14%) presented with a GCS score of 14. The majority of surgical procedures were orthopedic (86%). Diagnostic peritoneal lavage was performed in 55 (26%) patients, and computed tomographic scans were obtained in 155 (74%) patients. Three (1.4%) intraperitoneal injuries were diagnosed in the study population. Two of the injuries were stable grade 1 liver injuries, and missed diaphragmatic injury was diagnosed on postadmission day 1. CONCLUSION: Before emergent extra-abdominal trauma surgery, abdominal evaluation with physical examination is sufficient to identify surgically significant abdominal injury in the awake and alert blunt trauma patient. Screening with additional studies does not impact patient outcome. 相似文献

Background
Antimicrobial prophylaxis (AMP) can reduce the risk of surgical-site infection (SSI) following many types of surgery, particularly spinal surgery. After publication of the Guideline for Prevention of Surgical Site Infection by the Centers for Disease Control and Prevention in 1999, a large number of studies confirmed the effectiveness of AMP. However, because the concept of AMP is not clear in Japan, the duration of postoperative AMP tends to be long. The purpose of this study was to compare the infection rates following spinal surgery for postoperative AMP versus no postoperative AMP. 相似文献12.

BACKGROUND: Indirect laryngoscopy (IDL) is often performed prior to thyroid surgery to detect pre-existing vocal cord pathology. METHODS: A retrospective chart review of 201 patients undergoing thyroid surgery at the Prince of Wales Hospital was undertaken in order to study the patterns of pre-operative and postoperative voice changes and IDL findings. RESULTS: A total of 9% of patients had pre-operative voice symptoms, and 22% of this group had abnormalities detected on pre-operative IDL. Of 160 documented IDL, 4% revealed vocal cord pathology in asymptomatic patients, including an asymptomatic recurrent laryngeal nerve palsy. CONCLUSIONS: Indirect laryngoscopy remains a useful but flawed pre-operative screening tool for patients with voice symptoms, but the literature suggests that more advanced phoniatric tests will provide superior diagnostic sensitivity. The role of routine pre-operative laryngoscopy for asymptomatic patients is of debatable value. 相似文献

In deformity surgery in adults, pseudarthrosis remains an important cause of progressive deformity and postoperative pain. Revision surgery for pseudarthrosis in the lumbar spine is a difficult challenge with failure rates of as much as 50% using posterior surgery alone. Treatment of pseudarthrosis of the thoracic spine has not been well-described. The purpose of the current study was to review the long-term clinical and radiographic results of posterior-only surgery for the treatment of pseudarthrosis in the thoracic spine. Using a posterior extension osteotomy through the identified pseudarthrosis with reinstrumentation and autogenous bone grafting, an improvement of regional sagittal balance was shown and reliable clinical outcomes were obtained. A single-stage posterior revision surgery with extension osteotomies through the regions of pseudarthrosis coupled with rigid internal fixation and autogenous bone grafting is an effective technique for treatment of pseudarthrosis of the thoracic spine. This technique improves regional sagittal deformity and leads to reliable arthrodesis. Combined anterior and posterior surgery was not necessary for effective treatment of thoracic pseudarthrosis in this series. 相似文献

Thirty-two pigs were randomized into group I (aortic cross clamping, antegrade cardioplegia, moderate hypothermia) and group II (normothermia, beating empty heart). Groups were subdivided into subgroups A, B and C, receiving no lung perfusion, perfusion with arterial blood and perfusion with venous blood. Swan-Ganz catheter was used to take mean pulmonary artery pressure which would be used as lung perfusion pressure. Cardiopulmonary bypass (CPB) was established through cannulating aorta and double venae cavae, mechanical ventilation was interrupted and lung perfusion was carried out for 30 min. Blood samples and pulmonary specimens were withdrawn pre- and postoperatively for gasometrical, histological and genic analyses. Postoperative comparison revealed that pulmonary vascular resistance was lower in IC than IA (P=0.01) and it was lower in IIC than IIA (P=0.005). Subgroup IIB had increasing venous oxygen tension (P=0.01) as well as arterial and venous oxygen saturation (P=0.01) compared to IIA. Arterial oxygen saturation was decreased in IIC vs. IIA (P=0.006). Histological differences were observed between subgroups A and B as well as A and C (P=0.003). Lung perfusion during CPB may improve pulmonary hemodynamic performance, optimize gas exchange and maintain cellular integrity. 相似文献

OBJECTIVE: To find out the incidence and type of external laryngeal nerves during operations on the thyroid, and to assess the role of a nerve stimulator in detecting them. DESIGN: Prospective, non-randomised study. SETTING: Teaching hospital, Malaysia. SUBJECTS: 317 patients who had 447 dissections between early January 1998 and late November 1999. MAIN OUTCOME MEASURES: Number and type of nerves crossing the cricothyroid space, and the usefulness of the nerve stimulator in finding them. RESULTS: The nerve stimulator was used in 206/447 dissections (46%). 392 external laryngeal nerves were seen (88%), of which 196/206 (95%) were detected with the stimulator. However, without the stimulator 196 nerves were detected out of 241 dissections (81%). The stimulator detected 47 (23%) Type I nerves (nerve > 1 cm from the upper edge of superior pole); 86 (42%) Type IIa nerves (nerve < 1 cm from the upper edge of superior pole); and 63 (31%) Type IIb nerves (nerve below upper edge of superior pole). 10 nerves were not detected. When the stimulator was not used the corresponding figures were 32 (13%), 113 (47%), and 51 (21%), and 45 nerves were not seen. If the nerve cannot be found we recommend dissection of capsule close to the medial border of the upper pole of the thyroid to avoid injury to the nerve. CONCLUSION: Although the use of the nerve stimulator seems desirable, it confers no added advantage in finding the nerve. In the event of uncertainty about whether a structure is the nerve, the stimulator may help to confirm it. However, exposure of the cricothyroid space is most important for good exposure in searching for the external laryngeal nerve. 相似文献

PURPOSE: Whether antireflux implantation techniques are necessary in adults who undergo ileal ureteral substitution is controversial. We prospectively evaluated the correlation between reflux and renal function in 19 patients who underwent ileal ureteral substitution with no antireflux implantation technique. MATERIALS AND METHODS: Followup included clinical evaluation, serum creatinine, blood gasses, excretory urogram, cystogram and dynamic selective renographic clearance on technetium mercaptotriglycine renal scans. All patients were followed for a minimum of 4 years except 2 who died 26 and 43 months postoperatively. Mean followup was 57 months (range 48 to 72). RESULTS: Despite reflux, renal scans indicated a significant increase in renal function in all patients. Vesico-ileal reflux was present in 9 cases and reflux in the renal pelvis occurred in only 3. Reflux occurred in only 3 of 10 patients with ileal segments longer than 15 cm., and did not reach the renal pelvis. CONCLUSIONS: Reflux appears to have no detrimental effect on renal function in adults with ileal ureters and, therefore, an antireflux procedure is unnecessary. In addition, an ileal segment longer than 15 cm. appears to safeguard the renal pelvis against visible reflux stemming from pro-grade intestinal peristalsis. 相似文献

It has been more than 30 years since the introduction of endoscopic sphincterotomy for the management of choledocholithiasis. Once introduced, this endoscopic intervention subsequently enabled clinicians to witness the natural history of leaving the gallbladder in situ once the common duct calculi were removed. Because many people were free of symptoms once the common bile duct was cleared of stones, patients and physicians alike soon questioned whether it was necessary to remove the gallbladder at all. Despite more than two decades of clinical research and numerous published reports, the answer to this question remains elusive. Similarly, the management algorithm for choledocholithiasis in patients with an intact gallbladder remains controversial. We review the available key data regarding this question. Importantly, there are only three prospective, randomized trials that have examined the need for cholecystectomy after endoscopic sphincterotomy, with case studies constituting most of the published reports. Consequently, the literature on this topic remains inconclusive, weakened by its retrospective approach, considerable variability between the patients studied, inconsistent inclusion and exclusion criteria, and frequently poor patient follow-up. Nonetheless, the preponderance of data favor removing the gallbladder after endoscopically clearing the common bile duct of gallstones because an estimated 25% of patients will experience recurrent symptoms within a 2-year follow up period. Recognizing the existence of various mitigating clinical factors, we advocate adopting a selective wait-and-see approach for high-risk patients, especially those with a life expectancy of less than 2 years or severely debilitating comorbidities. 相似文献
