ObjectiveTo explore the effect of laparoscopic partial recto-sigmoid resection with rectopexy for adult complete rectal prolapse. MethodsClinical data of 32 adult patients with complete rectal prolapse who underwent laparoscopic partial recto-sigmoid resection with rectopexy in our hospital from May. 2010 to May. 2013 were analyzed. ResultsAll operations were performed successfully and all patients were cured, no one transferred to open surgery. The mean of operation time was 114.7 min (95-167 min), the mean of operative blood loss was 80 mL (55-150 mL), and the mean of hospital stay was 9.8 d (6-14 d). All patients were followed up for 3-48 months (mean of 25.6 months), and anal function of them recovered well. During the follow-up period, there were no operative complications and recurrent case. ConclusionsLaparoscopic partial recto-sigmoid resection with rectopexy is a safe and effective procedure for the treatment of adult complete rectal prolapse, with minimal invasion, quick recovery, and a low recurrence rate. It provides a novel surgical method with a high value of clinical application.
ObjectiveTo provide the evidence for diagnosis and treatment of the complication by describing the distribution and drug sensitivity of pathogens in patients with prosthetic joint infection (PJI) after primary total knee arthroplasty (TKA). MethodsBetween January 2003 and June 2013,65 cases (65 knees) with PJI after primary TKA were treated.There were 28 males and 37 females with an average age of 63.2 years (range,37-80 years).The median interval between PJI and primary TKA was 2.8 years (range,2 weeks to 11 years),including 29 left knees and 36 right knees.Prosthesis loosening could be found in 27 cases by X-ray examination.The average value of C-reactive protein and erythrocyte sedimentation rate was 37.4 mg/L (range,12.5-197.0 mg/L) and 63.2 mm/1 h (range,29.3-73.8 mm/1 h) respectively.Preoperative and intraoperative synovial fluid as well as intraoperative tissue samples should be submitted for aerobic and anaerobic culture.The four types of infections were made according to the Tsukayama et al.classification standards. ResultsThe patients were all diagnosed as having PJI.There were 5(7.69%) type I infections,4(6.15%) type ⅡA,8(12.31%) type ⅡB,3(4.62%) type Ⅲ,and 45(69.23%) type IV according to the Tsukayama et al.classification standard.Bacterial culture results were negative in 12 cases and positive in 53 cases,the main pathogen was Gram-positive cocci (39/53).The most common organism identified was Coagulase-negative Staphylococcus (24/53) followed by Staphylococcus Aureus (12/53).Resistant bacterium accounted for 61.11%(22/36) of Staphylococcus.These bacterium were all sensitive to vancomycin,linezolid,meropenem,and fluconazole;and highly resistant to erythrocin,penicillin,and cefoxitin.The main pathogenic bacteria of Coagulase-negative Staphylococcus and Staphylococcus aureus had highest resistant rate to penicillin. ConclusionGram-positive cocci is the main pathogen in patients with PJI after primary TKA,which is highly resistant to penicillin and macrolides.Antibiotic treatment of this complication should be based on the result of drug sensitivity test,vancomycin and linezolid may be used before the result of drug sensitivity test.It is important to pay attention to rare and multiple resistant bacteria.
ObjectiveTo explore the clinical characters and histopathologic differences between patients with culture-positive and culture-negative prosthetic joint infection (PJI). MethodsBetween January 2012 and July 2013, 66 PJI patients in accord with diagnostic criteria were enrolled. According to the results of preoperative aspiration and intraoperative cultures, the patients were divided into culture-negative group (CN group, n=21) and culture-positive group (CP group, n=45). There was no significant difference in gender, age, height, weight, and body mass index between 2 groups (P>0.05). Preoperative C reactive protein (CRP), erythrocyte sedimentation rate (ESR), and prosthesis survival time were compared between 2 groups. Intraoperative frozen sections and paraffin sections were both performed to identify infections, and histological typing was performed according to Morawietz's methods. ResultsThe preoperative CRP was (1.29±1.84) mg/ dL in CN group and (5.08±9.57) mg/dL in CP group, showing significant difference (t=2.094, P=0.038). The preoperative ESR was (22.86±28.42) mm/1 h in CN group and (36.74±31.26) mm/1 h in CP group, showing significant difference (t=7.761, P=0.000). The median survival time of prosthesis was 72 months (range, 8-504 months) in CN group and 25 months (range, 15 days-300 months) in CP group, showing significant difference (U=2.231, P=0.026). Morawietz's histological typing results showed that 2 cases were rated as type I, 7 cases as type II, and 12 cases as type III in CN group; 6 cases were rated as type I, 25 cases as type II, 13 cases as type III, and 1 case as type IV in CP group. The positive culture rate was 68.18% (45/66), and pathogenic bacteria was dominated by Staphylococcus, accounting for 68.89%. ConclusionThe patients with culture-negative PJI have slow onset and mild inflammatory response, so comprehensive diagnosis should be made based on pathological detection, laboratory examination, and intraoperative cultures.
ObjectiveTo evaluate the inflammatory markers in patients with ankylosing spondylitis (AS) or non-inflammatory diseases undergoing total hip arthroplasty (THA) and to ascertain the variation trend of perioperative inflammatory markers and the influence of inflammation markers after THA. MethodsBetween January 2013 and December 2014, 153 consecutive patients with AS were included. According to the range of motion (ROM), the patients were divided into ankylosis group (ROM: 0°; group A, n=92) and stiff group (ROM: 3-46°; group B, n=61); 120 noninflammatory diseases patients having no bacterial infection and undergoing primary THA served as non-inflammatory group (group C). The inflammatory markers including C-reactive protein (CRP), interleukin-6 (IL-6), and erythrocyte sedimentation rate (ESR) concentrations were measured before operation and at 1, 3, 5, and 7 days after operation, and the complication was observed. ResultsPerioperative serum CRP, IL-6, and ESR increased at first after operation, and then decreased in 3 groups. There were significant differences in CRP and ESR between at pre- and post-operation (P<0.05); the IL-6 at 1, 3, and 5 days after operation were significantly higher than that at preoperation (P<0.05), but no significant difference was found between at 7 days and at preoperation (P>0.05). CRP, IL-6, and ESR of group B were significantly higher than those of group A at preoperation (P<0.05); CRP and IL-6 of groups A and B were significantly higher than those of group C at preoperation and at 1 day after operation (P<0.05); ESR of groups A and B was significantly higher than that of group C at preoperation, and at 1 day and 3 days after operation (P<0.05); and no significant difference was shown among 3 groups at the other time points (P>0.05). No inflammatory activity or increased complication was observed. ConclusionAS and non-inflammatory diseases show similar change trend of inflammatory markers at preand post-operation. The inflammatory activity of AS has no significant effect on the changes of inflammation markers and does not increase the incidence of postoperative complications.
ObjectiveTo investigate the clinical characteristic differences of cementless total hip arthroplasty (THA) between with and without subtrochanteric femoral shortening osteostomy in Crowe type IV developmental dysplasia of the hip (DDH). MethodsBetween January 2006 and March 2012, 21 patients (21 hips) with Crowe type IV DDH who underwent primary THA were enrolled according to inclusion criteria. According to whether subtrochanteric femoral shortening osteostomy was performed during THA or not, the patients were divided into 2 groups: THA with osteostomy group (n=9) and THA without osteotomy group (n=12). There was no significant difference in gender, age, body mass index, and hip Harris score between 2 groups (P>0.05) except leg length discrepancy (t=-3.170, P=0.005). The operation time, blood loss, postoperative drainage, complications, and radiography data were compared to evaluate the clinical characteristics. ResultsThe operation time, blood loss, and postoperative drainage of osteotomy group were all significantly greater than those of no osteotomy group (P<0.05). All patients achieved primary healing of incision; 1 patient (1 hip) had transient sciatic nerve symptom in osteotomy group. The average follow-up time was 53 months (range, 28-88 months). The X-ray films showed good fracture healing at 3-6 months after operation in osteostomy group. No prosthetic loosening or dislocation was found. The hip Harris score was 90.67±4.06 in osteostomy group and 92.17±3.27 in no osteostomy group, showing no significant difference between 2 groups (t=-0.938, P=0.360). The leg length discrepancy was (0.22±0.26) cm in osteostomy group and (0.18±0.27) cm in no osteostomy group, showing no significant difference (t=107.000, P=0.546). The leg length discrepancy was found in 6 patients of osteotomy group and 5 patients of no osteotomy group. One patient complained of thigh pain in osteotomy group; 2 patients had slight limp (Trendelenburg +) in no osteotomy group. ConclusionTHA can improve joint function and increase limb length in the treatment of Crowe type IV DDH. Subtrochanteric shortening osteotomy is an effective treatment which can be performed according to preoperative template measurement, leg length shortening, and the soft tissue tension.
ObjectiveTo evaluate the application and effectiveness of bilateral total hip arthroplasty and total knee arthroplasty in the treatment of severe inflammatory arthropathies. MethodsBetween September 2008 and September 2015, 31 patients with severe inflammatory arthropathies were treated with bilateral total hip arthroplasty and total knee arthroplasty. Of 31 cases, 22 were male and 9 were female with an average age of 30 years (range, 20 to 41 years); there were 15 cases of rheumatoid arthritis and 16 cases of ankylosing spondylitis with an average onset age of 14 years (range, 5-28 years); all 4 ankylosed joints were observed in 11 cases, 3 ankylosed joints in 2 cases, 2 ankylosed joints in 6 cases, 1 ankylosed joint in 1 case, and no ankylosed joint in 11 cases. Before operation, the hip range of motion (ROM) value was (17.82±28.18)°, and the knee ROM value score was (26.45±30.18)°; the hip Harris score was 29.64±11.58, and the hospital for special surgery (HSS) score was 27.07±11.04. The patients were grouped and compared in accordance with etiology and ankylosed joint. ResultsOne-stage arthroplasty was performed in 1 case, two-stage arthroplasty in 22 cases, three-stage arthroplasty in 7 cases, and four-stage arthroplasty in 1 case. The total operation time was 325-776 minutes; the total blood loss was 900-3 900 mL; the total transfusion volume was 2 220-8 070 mL; and the total hospitalization time was 21-65 days. The patients were followed up 12-94 months (mean, 51 months). The hip and knee ROM values, Harris score and HSS score at last follow-up were significantly improved when compared with preoperative ones (P < 0.05). The subjective satisfaction degree was good in 16 cases, moderate in 10 cases, and poor in 5 cases. Periprosthetic infection occurred in 2 cases (3 knees), joint stiffness in 3 cases (6 knees), joint instability in 1 case (1 knee), leg length discrepancy of > 2 cm in 2 cases, and flexion deformity of 10° in 1 case (1 knee). The hip and knee ROM values, Harris score and HSS score showed no significant difference between patients with ankylosing spondylitis and patients rheumatoid arthritis at last follow-up (P > 0.05). The hip and knee ROM values of the patients with ankylosed joint were significantly lower than those of patients with no ankylosed joint (P < 0.05); the Harris score and HSS score of the patients with ankylosed joint were lower than those of patients with no ankylosed joint, but no significant difference was found (P > 0.05). ConclusionA combination of bilateral hip and knee arthroplasty is an efficient treatment for severe lower extremities deformity, arthralgia and poor quality of life caused by inflammatory arthropathies. However, the postoperative periprosthetic infection and stiffness of knee are important complications influencing the effectiveness of operation.
