Objective Minimally invasive technique was used in the treatment of pectus carinatum. Indication, techni-cal details and perioperative complication are discussed in this paper. Methods From March 2008 to January 2009, 6 patients with pectus carinatum underwent minimal invasive operation by using the principle of Nuss procedure in which pressure applied through a curved steel bar that was placed subcutaneously anterior to the sternum, via lateral thoracic incisions. Preoperative CT scan were performed and Hailer index was used as operative indication. Results The average age of patients was (13.6 ± 1.94) years (range, 10 - 16 years). They were all males. The mean operation time was (104.17 ± 15.63) minutes. The av-erage blood loss was (5.17±2.56) ml. The mean hospital stay was (5.67±0.82) days. Postoperative follow-up was 1 -11 months. Displacement of the stablizer was the only complication that was corrected by further fixation procedure. COnClusion The minimally invasive technique for the treatment of peetus earinatum is safe and effective with minimal complications. It can be selected as an alternative techniques and the appropriate age for this procedure is 10-16 years. 相似文献

Transperineal prostate biopsy is a procedure that can be used to obtain histological samples from the prostate. To improve both the quality of the biopsy core samples and prostate cancer detection, we are currently performing a prospective, randomized trial comparing prostate biopsy samples obtained using an 18 G-needle to those obtained using a 16 G-needle. The aim of this preliminary study was to evaluate pain and complication rates in both groups in order to assess whether performing a prostate biopsy with a larger calibre needle is a feasible procedure. One hundred and eighty-seven patients undergoing transperineal prostate biopsy were prospectively evaluated and divided into two groups. The first group (94 patients, Group A) received a transperineal prostate biopsy using a 16 G-needle and the second group (93 patients, Group B) underwent transperineal prostate biopsy with an 18 G-needle. Anaesthesia was obtained with a single perineal injection at the prostatic apex in all subjects. A visual analogue scale (VAS) and facial expression scale (FES) were used to assess pain during multiple steps of the procedure in each group. A detailed questionnaire was used to obtain information about drug use because it could potentially influence the pain and complications that patients experienced. Two weeks after the procedure, early and late complications were evaluated. Statistical analysis was carried out using non-parametric tests. Prostate Specific Antigen (PSA) and drug use were similar at baseline between the two groups. Pain during prostate biopsy, which was measured with both the VAS and FES instruments, did not differ significantly between the 18- and 16 G-needle groups, and no significant differences were found in early or late complication rates between the groups. Transperineal prostate biopsy with a 16 G-needle is a feasible Further studies with larger patient populations are required to prostate cancer detection rates. procedure in terms of pain and complication rates. assess whether or not this procedure can improve 相似文献

AIM:To analyze the differences in outcomes and the clinical impact following pancreatoduodenectomy(PD)in patients with and without aberrant right hepatic artery(aRHA).METHODS:All patients undergoing PD between January 2008 and December 2012 were divided into two groups,one with aRHA and the other without.These groups were compared to identify differences in the intraoperative variables,the oncological clearance and the postoperative morbidity,mortality and hospital stay.RESULTS:A total of 225 patients underwent PD,of which 43(19.1%)patients were found to have eitheraccessory or replaced right hepatic arteries(aRHA group).The aRHA was preserved in 79%of the patients.There was no significant difference in the intraoperative blood loss but operative time was prolonged,reflecting the complexity of the procedure[420±44(240-540)min vs 480±45(300-600)min,P0.05)].There were no differences in the incidence of postoperative complications(pancreatic leak,pancreatic fistula,delayed gastric emptying and mortality)and hospital stay.Oncological clearance in the form of positive resection margins[13(7.1%)vs 3(6.9%)]and lymph node yield were also similar in the two groups.CONCLUSION:An aRHA is found in approximately one fifth of patients undergoing PD.Preservation is technically possible in most patients and can increase the operative complexity but does not negatively affect the safety or oncological outcomes of the procedure. 相似文献

Objective To assess the efficacy of laryngeal mask airway Supreme (LMA Supreme) used in patients undergoing laparoscopic surgery. Methods One hundred and twenty ASA I or Ⅱ patients of both sexes aged 35-60 yr weighing 48-85 kg undergoing elective laparoscopic surgery were randomized to 2 groups ( n = 60 each): LMA Supreme group (group S) and tracheal intubation group (group T). Mallampati test was performed before operation in both groups. The patients were classified as I - Ⅲ . In group S the LMA Supreme was inserted after induction of anesthesia with sufentanil 0.2 fig/kg, propofol 2-3 mg/kg and vecuronium 0.1 mg/kg. A gastric tube was inserted through the drain tube of the LMA Supreme. In group T the patients were intubated under direct laryngoscopy. The success rate, LMA placement/intubation time, success rate of gastric tube placement, airway seal pressure, SpO2, PETCO2 , peak airway pressure and complications (hypoxemia, nausea and vomiting, choking hoarseness, sore throat and regurgitation of gastric contents) were recorded. The duration of surgery, anesthesia time, extubation time and emergence time were also recorded. Results There was no significant difference in the success rate between the two groups. The placement and removal time and recovery time were significantly shorter in group S than in group T. The airway seal pressure was (25 ±4) cm H2O in group S. SpO2, PETCO2 and peak pressure were within normal range in both groups. The incidence of postoperative hypoxemia, choking and sore throat were significantly lower in group S than in group T. Conclusion LMA Supreme can provide adequate ventilation during operation with less complications and can be used effectively for laparoscopic surgery. 相似文献

AIM: To analyze the results of laparoscopic colectomy in complicated diverticular disease.METHODS: This was a retrospective cohort study conducted at an academic teaching hospital. Data were collected from a database established earlier, which comprise of all patients who underwent laparoscopic colectomy for diverticular disease between 2000 and 2013. The series was divided into two groups that were compared: Patients with complicated disease(abscess, perforation, fistula, or stenosis)(G1) and patients undergoing surgery for recurrent diverticulitis(G2). Recurrent diverticulitis was defined as two or more episodes of diverticulitis regardless of patient age. Data regarding patient demographics, comorbidities, prior abdominal operations, history of acute diverticulitis, classification of acute diverticulitis at index admission and intra and postoperative variables were extracted. Univariate analysis was performed in both groups.RESULTS: Two hundred and sixty patients were included: 28%(72 patients) belonged to G1 and 72%(188 patients) to G2. The mean age was 57(27-89) years. The average number of episodes of diverticulitis before surgery was 2.1(r 0-10); 43 patients had no previous inflammatory pathology. There were significant differences between the two groups with respect to conversion rate and hospital stay(G1 18% vs G2 3.2%, P = 0.001; G1: 4.7 d vs G2 3.3 d, P < 0.001). The anastomotic dehiscence rate was 2.3%, with no statistical difference between the groups(G1 2.7% vs G2 2.1%, P = 0.5). There were no differences in demographic data(body mass index, American Society of Anesthesiology and previous abdominal surgery), operative time and intraoperative and postoperative complications between the groups. The mortality rate was 0.38%(1 patient), represented by a death secondary to septic shock in G2.CONCLUSION: The results support that the laparoscopic approach in any kind of complicated diverticular disease can be performed with low morbidity and acceptable conversion rates when compared with patients undergoing laparoscopic surgery for recurrent diverticulitis. 相似文献

AIM: To determine whether obese patients undergoing laparoscopic surgery within an enhanced recovery program had worse short-term outcomes.METHODS: A prospective study of consecutive patients undergoing laparoscopic colorectal resection was carried out between 2008 and 2011 in a single institution. Patients were divided in groups based on body mass index(BMI). Short-term outcomes including operative data, length of stay, complications and readmission rates were recorded and compared between the groups. Continuous data were analysed using t-test or oneway Analysis of Variance. χ2 test was used to compare categorical data.RESULTS: Two hundred and fifty four patients were included over the study period. The majority of individuals(41.7%) recruited were of a healthy weight(BMI 25), whilst 50 patients were classified as obese(19.6%). Patients were matched in terms of the presence of comorbidities and previous abdominal surgery. Obese patients were found to have a statistically significant difference in The American Society of Anesthesiologists grade. Length of surgery and intra-operative blood loss were no different according to BMI.CONCLUSION: Obesity(BMI 25) does not lead to worse short-term outcomes in laparoscopic colorectal surgery and therefore such patients should not be precluded from laparoscopic surgery. 相似文献

The prevalence of pectus excavatum is low but many patients are disabled from this thoracic deformity. The Nuss operation is a well-established surgical correction, however, until recently it has been rarely used in Europe. We have performed the Nuss operation regularly between 2001 and 2006 where a total of 383 patients were operated on for pectus excavatum. The indication for surgery was disabling cosmetic appearance as described by the patient. Patient records were reviewed for retrospective analysis. The median age was 16 years (range 7-43) and 86% were males. A satisfactory peri-operative result was achieved in all but one patient with one pectus bar (81%), two bars (19%) and three bars in one patient. Postoperative complications included bleeding, pleural effusion, seroma and deep infection. Seven patients were reoperated because the bar dislocated. At present the bars have been removed in 73 patients and their final result was excellent in all but one. The Nuss procedure for pectus excavatum can be implemented with excellent early results and few complications. There is a surprisingly high demand for surgical correction of pectus excavatum and the number of referred patients continues to increase as patients learn about the ease of this procedure and its excellent results. 相似文献

Purpose
In a few patients, cardiac perforation and aortic injury have occurred during the Nuss procedure for pectus excavatum. The article details a modification of this procedure that enables the prevention of fatal complications.Methods
Our subjects were 22 males and 13 females with pectus excavatum who were aged 8.2 ± 3.7 years. Their Haller's computed tomography index was 5.2 ± 1.5. An introducer is inserted into the pleura between the sternum and thymus instead of the thoracic depression under right thoracoscopic guidance. After the introducer reaches the internal cranial position of the left nipple, the thoracoscope is shifted to the left thoracic cavity. The introducer is subsequently guided to the left highest intercostal space under left thoracoscopic guidance.Results
A single bar was inserted in 34 patients; 2 bars were required in 1 patient. The operating time was 95 ± 27 minutes and blood loss was 11 ± 6 g. Cardiac perforation did not occur in any patient.Conclusions
Our modified technique has certain advantages: (1) the introducer does not rub against the pericardium and heart; (2) the tip of the introducer can be observed at all times with a thoracoscope; (3) the anterior mediastinum between the left and right thoracic cavities is very narrow at the cranial level; (4) the introducer can be accurately directed to the left highest intercostal space; and (5) hemostasis and no injury of the bilateral thoracic organs can be confirmed. 相似文献20.
