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 identify the postoperative function and short-term outcome of Global Modular Replacement System (GMRS) for reconstruction of defect after removal of tumor so as to supply information for cl inical appl ication. Methods Between March 2007 and May 2009, 30 l imb-salvage cases reconstructed with GMRS were retrospectively reviewed, including 18 males and 12 females with a median age of 25 years (range, 11-57 years). The preoperative diagnoses were osteosarcoma in 15 cases, mal ignant fibro-histiocytoma in 4, giant cell tumor in 3, chondrosarcoma in 2, and Ewing’s sarcoma and angiosarcoma in 1 respectively. The duration of symptom ranged from 1 to 15 months with an average of 5.6 months. There were 4 revision cases at mean time of 3.4 years after index surgeries. The locations were the proximal femur in 3 cases, distal femur in 22 cases, and proximal tibia in 5 cases. According to Enneking stage, 2 cases were rated as stage IB, 1 as stage IIA, and 27 as stage IIB. Four cases were compl icated by pathologic fracture. Results The average operation time was 165 minutes (range, 120-240 minutes); the mean blood loss was 448.3 mL (range, 100-1 500 mL); and the mean resection length was 14.1 cm (range, 7.5-22.5 cm). All the wounds healed by first intention. All 30 patients were followed up 10-35 months (22.3 months on average). Local recurrence occurred in 2 cases (6.7%) at 5 and 14 months respectively and distal metastasis occurred in 5 cases (16.7%) at 4-12 months (7.3 months on average) postoperatively. One patient died of multiple lung metastases at 10 months postoperatively. Twenty-nine patients survived at last follow-up, including 25 cases of tumor-free survival and 4 cases of tumor bearing survival. Aseptic loosening occurred in 2 cases (6.7%) at 1.5 years and 2 years postoperatively respectively. Deep infection occurred in 1 case (3.3%) at 1 year postoperatively. At last follow-up, the Musculoskeletal Tumor Society (MSTS) 93 scores were 4.6% ± 0.7% for pain, 3.7% ± 0.9% for function, 3.2% ± 1.3% for satisfactory degree, 4.3% ± 0.9% for orthesis, 3.7% ± 0.7% for walking, 3.3% ± 1.0% for gait; total score was 75.9% ± 14.2%. The Toronto Extremity Salvage Score (TESS) score was 87.0 ± 7.0. Conclusion Reconstruction for defect after removal of tumor with GMRS has satisfactory short-term outcome with good function recovery and low compl ication rate.
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 discuss the impacts of completion rate of fast track items on postoperative management of colorectal cancer surgery. Methods Between February 2010 and May 2010, 100 patients (Group “Year 2010”) were analyzed retrospectively, who were compared with 76 patients (Group “Year 2008”) from the same period of 2008. Postoperative recovery indexes, complications, and completion rate of fast track items were studied and compared. Results For major fast track items, the completion rates of restrict rehydration, early out-of-bed mobilization, early oral intaking, and management of gastric tube and drains were significantly higher in Group “Year 2010” than those in Group “Year 2008” (Plt;0.05). Meanwhile, the completion rate of urinary catheter management was significantly higher in Group “Year 2008” than that in Group “Year 2010” (Plt;0.05). In early rehabilitation, the first flatus of patients in Group “Year 2010” 〔(3.86±1.05) d〕 was significantly earlier than that in Group “Year 2008” 〔(4.28±1.22) d〕, Plt;0.05; for postoperative hospital stay, though, there was no statistically significant difference between two groups (Pgt;0.05). As to the complications, there was also no statistically significant difference between two groups (Pgt;0.05). Conclusions As the concepts of fast track surgery became increasingly favorable, completion rates of fast track items are increased. As a result, more and more fast track items turn into regular perioperative care. Although enhanced recovery has been achieved, better collaboration and localilzation are still needed to make the full advantage of fast track surgery.
Objective To compare the short-term outcomes between laparoscopic surgery and open surgery with fast-track (FT) in patients with colorectal cancer. Methods Between February 2008 and August 2008, the clinical data of 177 patients with colorectal cancer were analyzed retrospectively, who were divided into open group (n=122) and laparoscopic group (n=55) by surgery methods. Open group was further divided into FT group (n=66) and traditional group (n=56). Early rehabilitations were studied and compared among three groups. Results ① The baseline characteristics of patients among three groups were no significant differences (Pgt;0.05) exclude operation time. ② In early rehabilitation, the first flatus of patients in both the FT group 〔(3.86±1.01) d〕 and the laparoscopic group 〔(3.78±1.10) d〕 was significantly earlier than that in the traditional group 〔(4.43±1.25) d〕, Plt;0.05. ③ The first oral intaking in the FT group 〔(2.52±1.14) d〕 was earlier than that in the traditional group 〔(3.38±1.43) d〕 and the laparoscopic group 〔(5.04±2.24) d〕, Plt;0.05, while in the traditional group was earlier than that in the laparoscopic group (Plt;0.05). ④ For drainage management, both the FT group and the traditional group were significantly earlier than those in the laparoscopic group (Plt;0.05). ⑤ For postoperative hospital stay, in the FT group 〔(8.33±1.98) d〕 was also much shorter than that in the laparoscopic group 〔(10.55±3.14) d〕 and the traditional group 〔(10.82±3.76) d〕, Plt;0.05. ⑥ For the postoperative complications, there was no significant difference among three groups (Pgt;0.05). Conclusions FT surgery and laparoscopic technique could both enhance recovery of bowel function, and FT could also shorten postoperative hospital stay. However, further studies are needed to develop a better management.
