Objective To introduce a modified penile elongation method and observe its postoperative compl ications. Methods From January 1993 to December 2007, 130 patients with congenital short and small penis were divided into 2 groups: the routine group and the modified group, with 65 patients in each group. In the routine group, the patients were 18-55 years old (39.6 on average), and the penile length during erection was (4.9 ± 1.4) cm. In the modified group, the patients were 20-56 years old (35.4 on average), and the penile length during erection was (5.0 ± 1.5) cm. There was no significant difference between the two groups (P gt; 0.05). On the basis of scrotal flap which was transferred to cover the prolonged cavernous body of penis, the “+” shaped incision at the root of the penis was made in the routine group, and theincision was shifted upward by 1.5 cm in the modified group. And V-Y incision was made for the penises with more than 4 cm prolonged length. In order to compare the conditions in the two groups, no physical therapy was appl ied in 30 days after the operation. Results All the 130 patients’ incisions obtainedt heal ing by the firs intention, and all flaps survived successfully. Postoperative hydrophallus appeared differently between both groups. In the routine group, obvious hydrophallus appeared on the 3rd day after the operation and lasted for (15.11 ± 2.71) days, with 3 cases (4.62%) suffering from refractory hydrophallus. In the modified group, hydrophallus appeared on the 3rd day after the operation and lasted for (6.65 ± 0.29) days without any refractory hydrophallus. There was significant difference between the two groups in the duration of hydrophallus (P lt; 0.05). All patients were followed up for 6-8 months. After the operation, the shape and function of the penis were found good. The prolonged length was (4.9 ± 1.4) cm in the routine group and (5.0 ± 1.5) cm in the modified group. There was no significant difference between the two groups (P gt; 0.05). The satisfaction rate (according to the patients’ self-rating) was 95% and 98% in the routine group and the modified group, respectively. Conclusion The method using the scrotal flap transferred to cover the prolonged cavernous body of the penis is safe and of low compl ication rate. The modified method is more effective to abate postoperative hydrophallus.
【Abstract】 Objective To explore the cause of the perioprative period compl ication of scandinavian total anklereplacement(STAR) and to summarize the experience in the treatment and prevention. Methods From March 1999 toNovember 2006, 35 patients were given total ankle replacement(TAR) with STAR system. There were 19 males and 16 femaleswith an average age of 50.5 years (27 to 68 years), including 12 cases of posttraumatic arthritis, 8 cases of osteoarthritis and 15cases of rheumatoid arthritis. All patients had pain of ankle joint, swell ing and l imitation of joint motion. The disease coursewas 9-64 months. The curative effect was estimated by Kofoed total ankle scoring system. The mean preoperative ankle scorewas 29(6-48); the mean pain score was 18.3(0-35); the mean function score was 11.7(6-18); and the mean activity score was9.2(3-12). The type of all compl ications were record, and its cause, prevetion and treatment were analyszed. Results Thirtythreepatients achieved heal ing by first intention, 2 achieved delayed union because of infection. Twenty-eight patients werefollowed up 3-80 months (mean 43.5 months). Medial malleolus fracture occurred in 2 cases, unstable ankle joint introversion in2 cases, l imitation of ankle dorsiextension in 1 case and 1 case had hypoesthesia at intermediate dorsal skin of foot and 3rd-5thmetatarsal skin without obvious dysfunction; all were treated with symptomatic medication. The postoperative mean ankle scorewas 85.5 (58-95); the mean pain score was 48.3(35-50); the mean function score was 20.7(18-30); the mean activity score was17.2(16-20). There were statistically significant differences when compared with preoperative score(P lt; 0.01). The cl inical resultswere excellent in 16 patients, good in 9 patients and fair in 3 patients. The X-ray films showed no loosening and subsidence ofprosthesis. Conclusion Although STAR can retain the functions of the operated joint, it has its special compl ications. It isimportant to obey operation principle with proficient operative technique, to strictly control surgical indication and to intensifyperioperative period treatment so as to decrease the compl ications.
Objective To investigate the causes of the vacuum seal ing drainage (VSD) compl ications during treatment of extremity wounds. Methods Between February 2005 and February 2010, 174 patients with skin and soft tissue defect of extremities were treated with VSD. Among them, 12 patients (6.9%) had compl ications and the cl inical data were analyzed retrospectively. There were 7 males and 5 females aged from 17 to 65 years (mean, 36.1 years). Injury was caused bytraffic accident in 8 cases, and by machine extrusion in 4 cases. The locations were forearm in 3 cases, upper arm in 2 cases, thigh and calf in 1 case, calf in 4 cases, and foot in 2 cases. The size of defect ranged from 10 cm × 7 cm to 90 cm × 40 cm. The time from injury to hospital ization was 3-8 hours (mean, 4.2 hours). Results At 1 day postoperatively, moderate to severe anemia and hypokalemia occurred in 6 cases, and the hemoglobin value increased to 100 g/L and the electrolyte disorder was rectified after blood transfusion and fluid infusion. At 2 days, 2 patients had local skin allergic symptoms, and local rash disappeared after oral administration of Clarityne. At 3 days, 2 patients complained pain and the pain was released after the suction pressure was decreased by 50%; 2 patients had infection and received VSD demol ition, debridement and draining, and anti-infection treatment. Tissue necrosis occurred in 1 case at 4 days and pressure ulcer in 1 case at 5 days, VSD was immediately changed and wound was repaired by spl it thickness skin graft or local flap. Conclusion Compl ications associated with VSD therapy for the wounds of the extremities are not very common. Most causes are related to the location of wound, the technique of the operators, and the conditions of the patients.
Objective To summarize and analyze the operation-correlated compl ications of total knee arthroplasty (TKA)with posterior stabil ized prosthesis (PS). Methods From October 2000 to October 2007, 707 cases (816 knees) underwent TKA. All the TKA knees were divided equally into former and latter groups according to the operation time (408 knees for each group). In the former group (October 2000 to January 2005, n=350), there were 63 males (84 knees) and 287 females (324 knees), aging (63.5 ± 7.8) years. A total of 198 left knees affected and 210 right knees affected; 292 single kneesaffected and 58 both knees affected. There were 304 knees of osteoarthritis, 84 knees of rheumatoid arthritis and 20 knees of other disease. The disease course was (9.3 ± 5.6) years. The knee range of motion (ROM) was (97.2 ± 8.7)°, the HSS score was 47.4 ± 12.2. In the latter group (January 2005 to October 2007, n=357), there were 77 males (92 knees) and 280 females (316 knees), aging (62.7 ± 6.3) years. A total of 221 left knees affected and 187 right knees affected; 306 single knees affected and 51 both knees affected. There were 278 knees of osteoarthritis, 109 knees of rheumatoid arthritis and 21 knees of other disease. The disease course was (8.6 ± 5.1) years. The knee ROM was (101.1 ± 10.3)°, the HSS score was 49.3 ± 11.2. We modified the method of lateral patellar retinaculum release and used a new femoral rotational al ignment technique in the latter group. The intraoperative and postoperative compl ications were divided into mild, moderate and severe. The HSS score, ROM and compl ications of the knee were compared and analyzed statistically during the follow-up. Results The former group was followed up 5.3 years (1 to7 years), compl ications occurred in 278 knees (68.1%), including mild in 136 knees (33.3%), moderate in 135 knees (33.1%) and severe in 7 knees (1.7%). The latter group was followed up 2.1 years (0.5 to 3.5 years), compl ications occurred in 159 knees (39.0%), including mild in 111 knees (27.2%), moderate in 47 knees (11.5%) and severe in 1 knee (0.2%), and there was significant difference between them (P lt; 0.001). There was significant difference in increased ROM between the former group (6.0 ± 3.7)° and the latter group (14.4 ± 4.2)° after operation (P lt; 0.05). There was significant difference in increased HSS score between the former group (36.9 ± 3.7)and the latter group (44.0 ± 4.2) after operation (P lt; 0.05). Conclusion The TKA is a complex operation with innumerable potential compl ications. To accumulate operative experience and improve surgical skills are the key points to reduce the operation-correlated compl ications.
Objective To investigate the etiology, diagnosis, revascularization of upper l imb ischemia and the compl ications. Methods From March 2003 to February 2008, 72 cases of upper l imb ischemia were treated. There were 44males and 28 females, aged 19-90 years old (median 63 years old). The duration of the disease was 1 hour to 2 years. All cases had symptoms of l imb ischemia such as paleness, coldness, paralysis. According to individual condition, 72 patients accepted revascularizations including thromboembolectomy, reconstruction after traumatic injuries, pseudoaneurysm excision and angioplasty, balloon dilatation and stent implant, arterial repair, patch, vascular prosthesis or vein bypass/transplantation, and l igation or coarctation of fistula. Results Sixty patients (83.3%) recovered well after operation. Re-occlusion following thromboemboletomy was found in 6 patients (8.3%). And there were 4 patients (5.6%) with l imbs disturbance and muscles contracture and 2 patients (2.8%) with compartment syndrome in this series. The affected l imb had to be amputated in 2 patients (2.8%). And 1 patient (1.4%) died of cerebral hemorrhage because of anticoagulation 3 days after operation. All patients were followed up 1-6 years (mean 52 months) after operation. Four patients recurred and got improved after retreatments. The others got a good result with normal skin color and temperature, restoration of the radial and ulnar pulses, normal saturation of blood oxygen of finger ti p (gt; 90%) and patent blood flow of affected arteries was shown by color Doppler ultrasound. Conclusion The study indicates that identifying the etiology of upper l imb ischemia before operation and active revascularizations consistent with different causes are the key to treat the upper l imb ischemia.
Objective To investigate the causes and managements of acetabular fracture during primary total hip arthroplasty (THA). Methods Between May 2005 and July 2008, 9 patients (9 hi ps) suffered from acetabular fractures during primary THA. There were 1 male and 8 females with an average age of 63.3 years (range, 41-73 years), including 4 cases of developmental dysplasia of the hip, 2 cases of rheumatoid arthritis, 1 case of old femoral neck fracture, 1 case of avascular necrosis of femoral head, and 1 case of ankylosing spondyl itis. Three left hips and 6 right hips were involved. The preoperative Harris score was 40.4 ± 2.9. All the patients underwent cementless THA. Among nine acetabular fractures, 8 fractures were stable (2 anterior wall fractures and 6 posterior wall fractures), which were fixed by additional augmentation screws in 7 cases and accepted no special treatment in 1 case; 1 fracture was unstable (posterior wall fracture with posterior column incomplete fracture), which was treated by bone grafting and additional screws. Results The postoperative X-ray films showed that the position of the prosthesis were favorable. All incisions healed by first intention without early compl ication. Nine patients were followed up 1-4 years (mean, 2 years and 7 months). The Harris score was 87.8 ± 3.9 at last follow-up, showing significant difference when compared with the preoperative score (t=44.904, P=0.000). The X-ray films showed fracture heal ing at 8 weeks. No loosening occurred. Conclusion When primary THA is performed, the preoperative X-ray film should be studied and measured carefully, operation should be accurate and violence should be avoided. The diameter of the acetabular component should be equal to the diameter of a drill or not larger than 2 mm. In patients with severe osteoporosis, the diameter of the acetabular components should be the same diameter as a drill and additional screws are used to fix, or cemented cup is used. Once an acetabular fracture occurs during the primary THA, additional screw or bone grafting with additional screws should be chosen according to the fracture type and stabil ity, and good cl inical results can be expected.
Objective To compare the early compl ications of carotid stenting (CAS) and carotid endarterectomy (CEA) in treatment of carotid artery stenosis. Methods Between January 2005 and December 2007, 63 patients with carotid artery stenosis were treated with CEA in 36 cases (CEA group) and with CAS in 27 cases (CAS group). There were 42 males and 21 females with an average age of 67.5 years (range, 52-79 years). The locations were the left side in 28 cases and the rightside in 35 cases. The carotid stenosis was 60%-95% (mean, 79%). The major cl inical symptoms were stroke and transient ischemic attack. The cranial CT showed old cerebral infarction in 24 cases, lacunar infarction in 22 cases, and no obvious abnormal change in 17 cases. The encephalon, heart, and local compl ications were compared between 2 groups within 7 days after operation. Results In CEA group, encephalon compl ications occurred in 3 cases (8.3%), heart compl ications in 2 cases (5.6%), and local compl ications in 5 cases (13.9%); while in CAS group, encephalon compl ications occurred in 8 cases (29.6%), heart compl ications in 1 case (3.7%), and local compl ications in 3 cases (11.1%). The encephalon compl ication ratio of CAS group was significantly higher than that of CEA group (χ2=4.855, P=0.028); and there was no significant difference in other compl ications ratios between 2 groups (P gt; 0.05). Conclusion CEA is the first choice to treat carotid artery stenosis.
Objective To investigate the donor-site compl ications of the anterolateral thigh flap and its influencing factors. Methods Between July 1988 and July 2007, 427 patients were treated with anterolateral thigh flap. Among them, 33 patients had postoperative donor-site compl ications and their cl inical data were analyzed retrospectively. There were 21 malesand 12 females aged 14-47 years old (average 32.7 years old). The size of the wound defect ranged from 16 cm × 7 cm to 28 cm × 13 cm. The area of the flap harvested during operation ranged from 16 cm × 7 cm to 30 cm × 13 cm. The donor sites were treated by direct suture in 7 cases; free spl it-thickness skin graft in 23 cases, and reverse superficial epigastric artery flap repair in 3 cases. The size of graft in the donor site ranged from 10 cm × 5 cm to 18 cm × 8 cm. The occurrence of short-term (within 4 weeks) and long-term (over 6 months) compl ications were analyzed. Results All patients were followed up for 8-54 months (average 21 months). There were 26 patients (78.8%) with short-term and long-term compl ications and 7 patients (21.2%) with long-term compl ications. The short-term compl ications included skin graft necrosis in 23 cases (69.7%), wound infection in 17 cases (51.5%), and muscle necrosis in 2 cases (6.1%). The long-term compl ications included non-heal ing wounds in 21 cases (63.6%), serious scar in 28 cases (84.8%), discomfort in 25 cases (75.8%), and dysfunction of the quadriceps femoris in 16 cases (48.5%). Conclusion The occurrence of anterolateral thigh flap donor-site compl ications is related to the anatomical structure of the anterolateral thigh region, the surgical procedure, and the patient’s physique.
Objective To study the prevention and management of early compl ications associated with anterior cervical spinal surgery. Methods From November 1998 to December 2006, 363 cases were treated with anterior cervicalsurgery, including 268 males and 95 females aged 17-79 years．In these cases, 224 suffered from cervical spondylosis, 39 from cervical disc herniation, 87 from cervical trauma, 9 from cervical tumor and 4 from cervical tuberculosis. Forty-eight cases with anterior cervical surgery were fused by autogenous il iac bones, 132 cases with anterior cervical surgery were fused by autogenous il iac bones and anterior cervical spine locking plates, and 183 cases with anterior cervical surgery were fused by titanium mesh cage and anterior cervical spine locking plates. Results A total of 282 cases were followed up for 3 months to 5 years with the average of 1 year and 11 months. Twenty-three compl ications associated with surgery were found, with an incidence of 8.16%. Three cases of transient superior laryngeal nerve palsy recovered within 3-7 days after the restriction of l iquid diet and fluid replacement. Two cases of recurrent laryngeal nerve palsy recovered by 3-month pronunciation practice. One case of spinal cord injury was treated with medicine for dehydration and anti-inflammation, and was restored to preoperative muscle power of inferior extremity after 6 months. Two cases of CSF leakage were cured with moderate local compression and meticulous water-tight wound closure. Among the 10 patients with compl ications of internal fixation, one suffering mild dysphagia was reoperated, while the others were treated with cephal-cervico-thorax plaster external fixation and recovered with sol id fusion within 3-18 months. Among the 4 cases with cervical hematoma, 1 died of wrong rescue procedures and 1 was infected. Conclusion Adequate preoperative preparation, thorough understanding of anatomy related to the anterior approach and skilled surgical technique are essential for preventing the early postoperative compl ications of anterior cervical spinal surgery．
Objective To investigate the etiology, diagnosis, and treatment of acute carpal tunnel syndrome (ACTS) after reduction of Colles’ fracture. Methods Between December 2006 and June 2010, 22 patients with ACTS after reduction of Colles’ fracture were treated with expectant treatment and surgical treatment. There were 9 males and 13 females with an average age of 46.2 years (range, 23-60 years). Fractures were caused by traffic accident in 9 cases, fall ing in 8 cases, fall ing from height in 2 cases, hitting in 2 cases, and crushing in 1 case. The mechanism of fracture was direct violence in 3 cases and indirect violence in 19 cases. According to Gartland ＆ Werley classification, there were 2 cases of type I, 5 cases of type II, 14 cases of type III, and 1 case of type IV. Closed reduction was performed in 19 cases and open reduction and internal fixation (ORIF) in 3 cases. The average symptom time of ACTS after reduction of Colles’ fracture was 11.6 hours (range, 1 hour 30 minutes to 48 hours) in patients undergoing closed reduction and was 24 hours in 1 patient and 2 weeks in 2 patients undergoing ORIF. Expectant treatment was performed first, the forearms were put in neutral position in closed reduction cases; if there was no rel ief of ACTS symptom 1 week later, the mixture of 1 mL glucocorticosteroid and 1 mL 2% l idocaine was injected into carpal tunnel once a week for 2 weeks. The mixture was injected into carpal tunnel directly once a week for 2 weeks in ORIF cases. In the patients who failed to expectant treatments, ORIF was performed. Results In 7 cases of type III that failed expectant treatment, ACTS symptoms were rel ief completely after ORIF. All the 22 patients were followed up 12 months on average (range, 8-18 months). The average time of complete disappearance of median nerve compression symptom was 11 days (range, 2-25 days). All the patients had normal finger motion, sensation, and opposition of thumb with no sensation of anaesthesia and pinprick. The results of Tinel test, Phalen test, and Reverse Phalen test were all negative. The X-ray film showed good fracture reduction and heal ing with an average heal ing time of 6 weeks (range, 3-14 weeks). According to GU Yudong’s criteria for functionalassessment, the results were excellent in 18 cases and good in 4 cases; the excellent and good rate was 100%. Conclusion Malposition, displacement of fracture fragments, and ulnar deviation of the wrist after plaster immobil ization are the mostimportant risk factors for ACTS. Expectant treatments are recommended in patients with Colles’ fracture of types I, II, and IV,but surgical treatment is the first choice for Colles’ fracture of type III.
