Objective To explore the surgical method and cl inical short-term outcomes of internal fixation combined closed reduction with arthroscope aid in treating patellar fracture. Methods From June 2004 to July 2008, 42 patients with fresh simple patellar fracture underwent internal fixation combined closed reduction with arthroscope aid, included28 males and 14 females, aged 16-59 years (35 years on average). The locations were 19 left knees and 23 right knees. Injury was by traffic accident in 21 cases, by fall ing in 11 cases, by sports in 7 cases and by crush in 3 cases. All the patients had fresh closed fracture, including 38 cases of transverse fracture and 4 cases of stellate fracture. The Lysholm score was 68.60 ± 15.20; the proprioceptive function of the knee joints was (3.72 ± 0.12)°. The time from injury to operation was 3-42 hours (12 hours on average). After the treatment of affil iated injury under the arthroscope, patellar fracture was reduced with manipulation method, fracture was fixed with tensile force screw or modified tension band. Results All incisions obtained heal ing by first intention after operation, 42 patients were followed up for 12-39 months (16 months on average). The X-ray films showed callus at the fracture and the smooth cartilage surface 6-9 weeks (7 weeks on average) after operation. The flexed motion range of knee joint at last follow-up was at normal range in 38 cases, was l imited in 4 cases. Circumference of suffered l imbs 15 cm above the patella was the same as normal ones in 23 cases, atrophied 0.7 cm in 19 cases. There were no breakage of internal fixation and shift of fracture and patellofemoral arthritis at last follow-up. The proprioceptive function of the knee joints was (2.06 ± 0.11)° and the Lysholm score was 95.10 ± 3.92; all showing statistically significant differences when compared with preoperation (P lt; 0.05). Conclusion This treatment method has advantages as follows: mini-wound, early exercises and few compl ications, which can rinse articular cavity and repair the affil iated injury at the same time.
Objective To discuss whether age has an influence on short-term effect of intersphincteric resection (ISR) for elderly (≥75 years old) patients with ultra-low rectal or canal cancer or not. Methods From February 2016 to February 2017, 196 patients with ultra-low rectal or canal cancer received ISR in the Gastrointestinal Surgery Center of West China Hospital were eligible to include in this study, then they were divided into ≥75 years old group and <75 years old group according to the patients’ age. The intraoperative index, postoperative index, and complications rate were compared between these two groups. Results There were 113 cases in the ≥75 years old group, 83 cases in the <75 years old group, the baselines such as the gender composition, body mass index, tumor histology type, differentiation degree, tumor size, and distance from the anal margin had no significant differences ( P>0.05), but the preoperative anaesthetized ASA grade, proportions of pulmonary insufficiency, hypoproteinemia, anemia, hypertension, diabetes, and cardiac insufficiency of the ≥75 years old group were significantly higher than those of the <75 years old group (P<0.05). The operative time, intraoperative bleeding, and total complications rate had no differences between these two groups (P>0.05), the first exhaust time, the first eating time, the first defecation time, the first ambulation time, and hospitalization time of the ≥75 years old group were significantly longer than those of the <75 years old group (P=0.023, 0.037, 0.019, 0.020, and 0.012, respectively). There were no significant differences in the incidences of the anastomotic leakage, perianal infection, intestinal obstruction, and wound infection between these two groups (P>0.05). All the 196 patients were followed-up with an average follow-up of 7 months, there were 4 cases of recurrent patients, of which 3 were in the ≥75 years old group and 1 in the <75 years old group; there were 3 cases of death, of which 2 were in the ≥75 years old group and 1 in the <75 years old group. Conclusions Short-term recovery of elderly patients with ultra-low rectal or canal cancer is slower than younger patients because of poor preoperative conditions. ISR surgery is still safe and effective for elderly patients with ultra-low rectal or canal cancer and postoperative complications rate has no obvious increase, but it needs a surgeon’s skilled operation technology and multi-disciplinary team cooperation.
Objective To investigate the surgical technique and short-term effectiveness of anterior cruciate l igament (ACL) reconstruction with LARS artificial l igament. Methods Between November 2008 and April 2010, eighty patients withACL injury were treated with LARS artificial l igament under arthroscope and successfully followed up. There were 51 males and 29 females, aged from 17 to 43 years with an average of 29.2 years. The injuries were caused by sport in 63 cases, traffic accident in 14 cases, and bruise in 3 cases. There were 43 left knees and 37 right knees. The disease duration ranged from 10 days to 11 months. The anterior drawer test, Lachman test, and pivot shift test for all cases were rated as positive. The preoperative Lysholm score was 55.4 ± 5.7, Irgang score was 48.3 ± 6.2, and Larson score was 54.8 ± 7.4; and the International Knee Documentation Committee (IKDC) score was lower than normal level in all cases. Obl ique coronal MRI showed ACL injury in all cases. Residual ACL and synovium were preserved during surgery. Results All incisions healed by first intention without compl ication of infection or deep venous thrombosis. All patients were followed up 7 to 24 months with an average of 16.8 months. There were 3 cases of screws exposure toward femoral cortical bone, 2 cases of loosening tibial screw, and 1 case of knee extension l imitation, and they were cured after symptomatic treatment. No LARS artificial l igament rupture and joint fibrosis occurred during followup. At last follow-up, the results of anterior drawer test, Lachman test, and pivot shift test were positive in 2, 3, and 3 patients,respectively. There were significant differences in Lysholm, Irgang, and Larson scores of affected knees between preoperation and 6 weeks postoperatively, last follow-up, respectively (P lt; 0.05). The normal rate of IKDC score were 43.75% (35/80) and 97.50% (78/80) at 6 weeks postoperatively and last follow-up, respectively. Conclusion The viscoelastic properties of LARS artificial l igament is different from that of biological materials. The graft should be fixed at a relatively extension position to avoid knee extension l imitation and sl ight loosening of graft tension is permitted at flexion position. Good cl inical result could be achieved if the technique is well appl ied.
Objective To summarize the treatment method and to analyze short-term therapeutic effect of Pipkin fracture. Methods From January 2002 to January 2007, 14 cases of Pipkin fracture were treated. There were 10 males and 4 females with an average of 33.5 years (ranged from 28 to 52 years). Fractures were caused by traffic accident. According to Pipkin’s classification, there were 4 cases of type I, 6 cases of type II, 2 cases of type III and 2 cases of type IV. The time from injury to operation was 24 hours to 8 weeks. All patients received open reduction under Kocher-Langenbeck approach, mel iorative posterior-lateral approach or combined approaches. Absorbable screws and suture l ine internal fixation wereperformed in fracture of the femoral head, titanium cannulated screws were used to fix the femoral intertrochanteric fracture in type III, and acetabular tridimensional memory fixation systems were used to fix the posterior acetabular fractur in type IV. Results All cases had one-stage wound heal ing, no compl ications of deep infection and thrombosis of deep vein of lower l imb occurred. All the patients were followed up for 12 - 48 months (mean 26 months). One case of type III fracture for Pipkin had necrosis of femoral head after 1 year of reduction and fixation, and received total hip replacement; other patients achieved bony heal ing after 6-10 months (mean 8 months). According to D’Aubigue-Postel score, the results were excellent in 5 cases, good in 6 cases, fair in 2 cases and poor in 1 case; the excellent and good rate was 78.6%. Conclusion It is important for the patients with Pipkin fracture to early diagnose, to select proper operation approach, to stably fix fracture and to manage after operation in reducing compl ication and recovering hip joint function.
ObjectiveTo investigate the short-term effectiveness of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treatment of anterior pelvic ring fractures. MethodsBetween January 2012 and October 2013, 16 patients with anterior pelvic ring fractures were treated with MIPPO. There were 10 males and 6 females at the age of 20-63 years (mean, 41 years). The causes of injury were traffic accident in 9 cases and falling from height in 7 cases. The duration of injury to admission was 2 hours to 5 days (mean, 1 day). According to Tile classification, 8 cases were rated as type B2, 4 cases as type B3, 2 cases as type C1, and 2 cases as type C2. Of them, 2 cases had iliac wing fracture, and 4 cases had pelvic posterior ring fracture. The time from admission to operation was 3-12 days (mean, 6 days). ResultsThe bleeding volume was 60-120 mL (mean, 70 mL). All wounds healed by first intention. No postoperative complication of deep venous thrombosis or long-term continuous pain occurred. All cases were followed up 5-27 months (mean, 11.5 months). No clinical manifestation of lateral femoral cutaneous nerve injury or spermatic cord injury was found, and cremasteric reflex existed in males. All cases obtained bony union, and the healing time was 12-16 weeks (mean, 13 weeks). During the follow-up period, no loss of fracture reduction and no internal fixation loosening or broken were observed. According to Matta radiological evaluation criterion, 16 cases had anatomical reduction, and 3 cases had satisfactory reduction; according to Majeed scoring system of pelvic fracture, the results were excellent in 12 cases and good in 4 cases. ConclusionMIPPO for treatment of anterior pelvic ring fractures has the advantages of less intraoperative blood loss, few soft tissue complications, and low infection rate, and can get satisfactory short-term effectiveness.
ObjectiveTo compare the short-term outcome of 3-port and 5-port laparoscopic assisted radical resection for middle and high rectal cancer.MethodsWe retrospectively analyzed the clinical characteristics of 67 patients with middle and high rectal cancer who were treated in the Gastrointestinal Ward of Center of General Surgery in General Hospital of Western Theater Command of the Chinese People’s Liberation Army from January 2018 to December 2018. The operative, pathological, recent postoperative related indicators, and follow-up results of the two groups were compared and analyzed.ResultsAmong all the enrolled patients, 33 cases received 3-port laparoscopic surgery (3-port group) and 34 cases received 5-port laparoscopic surgery (5-port group). The total length of incision and the pain score of the Visual Analog Scale (VAS) on the 3rd postoperative day of the 3-port group were significantly better than those of the 5-port group (P<0.05). Peripheral incisal margins were negative in both two groups. However, there were no statistically significant differences in indicators such as operative time, intraoperative blood loss, operative conversion rate, hospitalization expenses, length of the distal margins, number of positive lymph nodes, number of lymph nodes harvested, time to the first flatus, time to the first ambulation, time to urinary catheter removal, time to drainage tube removal, time to the first oral intake, postoperative hospital stay, and postoperative complication rate (P>0.05). Thirty cases of the 3-port group were followed up for 12–24 months (median of 19 months), as well as 29 cases of 5-port group were followed up for 12–24 months (median of 19.5 months). There were no significant differences on the incidences of intestinal obstruction, local recurrence, distant metastasis, and death between the two groups (P>0.05).ConclusionCompared with the conventional 5-port laparoscopic surgery, the 3-port laparoscopic surgery could shorten the total length of incision and reduce the surgical trauma, suggesting that it is safe and effective.
Objective To evaluate the impact of body mass index （BMI） on short-term outcomes after intersphi-ncteric resection （ISR） for rectal cancer and anal cancer. Methods One hundred and ninety-nine cases of rectal cancer and anal cancer who were treated in Department of Gastrointestinal Surgery of West China Hospital of Sichuan University from Jan. 2009 to Dec. 2011 were enrolled retrospectively，and these cases were divided into underweight group （n=23），normal group （n=114），and overweight group （n=62） according to BMI. Postoperative indexes in early rehabilitation and complication of 3 groups were studied and compared. Results On the recovery indexes after ISR in early stage，there were no significant differences on the duration of first flatus，first defecation，first oral intake，first ambulation，and hospital stay among 3 groups （P＞0.05）. On the tube management，there were no significant differences on the duration of pulling out nasogastric tube and urinary catheter （P＞0.05），but duration of pulling out drain was longer in normal group and over-weight group （P＜0.05）. There were no significant differences on the incidence of postoperative complications among the 3 groups （P＞0.05），including anastomotic leakage，anastomotic bleeding，perianal infection，ileus，gastric retention，urinary retention， septicemia，wound infection，and recto-vaginal fistula. Conclusions BMI has little impact on short-term outcomes after ISR. Obesity does not increase the incidence of common complications for patients after ISR and does not influence recovery indexes with proper postoperative managements.
Objective To evaluate the early cl inical results of total knee arthroplasty (TKA) with JOURNEY prosthesis. Methods From September 2006 to May 2007, TKA with JOURNEY prosthesis was used to treat 32 patients in ATOS Cl inic, Germany. There were 21 males and 11 femals, aged 40-84 years old (average 65.6 years old). The locations were left knee in 13 cases and right knee in 19 cases, including 5 cases of traumatic arthritis, 19 cases of osteoarthritis and 8 cases of rheumatoid arthritis. All patients had pain and l imited range of motion (ROM) of knee. MRI scanning showed that cartilageand miniscus damaged in all cases. The disease course was 1 to 4 years (average 2.2 years). The CPM practice started 2 days after operation. Results The operative time was (75.0 ± 21.7) minutes. The blood loss was (280 ± 130) mL. All incision healed by first intention. Thirty-two patients were followed up 12 to 18 months (average 14.2 months). Hydrarthrosis occurred in 8 cases at 3-6 months postoperatively. Femur paraprosthesis fracture and implant dislocation occurred at 1 week and at 6 months in 2 cases, respectively. There were statistically significant differences in KSS score between preoperation and 3, 6, 12 months after operation (P lt; 0.05), between 3 months and 6, 12 months after operation (P lt; 0.05); there was no statistically significant difference in KSS score between 6 months and 12 months after operation (P gt; 0.05). There were statistically significant differences in pain score between preoperation and 3, 6, 12 months after operation (P lt; 0.05), and in ROM between 3 months and 6, 12 months after operation (P lt; 0.05). There was no statistically significant difference in ROM between preoperation and 3 months after operation (P gt; 0.05). Conclusion Ii is a simple way to TKA with JOURNEY prosthesis, which has a good results in early follow-up period.
ObjectiveTo evaluate the safety and short-term outcome of laparoscopic total mesorectal excision (TME) for the middle-lower rectal cancer in municipal hospital.MethodsThe pathological data of 94 patients with middle-lower rectal cancer (49 cases underwent laparoscopic TME, while 45 cases received open TME), who treated in The First People’s Hospital of Ziyang from Jan. 2015 to Jun. 2017, were retrospectively collected and analyzed.ResultsTwo patients (4.1%) in laparoscopy group were converted to open surgery. Compared with the laparotomy group, the laparoscopic group had significantly less volume of intraoperative bleeding, shorter abdominal incision, earlier time to the first flatus and liquid diet, and lower rate of 30-day postoperative complication (P<0.05), but had longer operative time (P=0.033). While there were no significant difference on postoperative stay, the specimen length, distal margin, and number of harvested lymph nodes between the 2 groups (P>0.05).ConclusionLaparoscopic TME is a feasible, safe, and minimally invasive technique for middle-lower rectal cancer, and produce more favourable short-term outcome than open surgery in municipal hospital.
