Gastrointestinal dysfunction is a common and major complication after surgery. The syndrome covers a wide spectrum of clinical signs, ranges from mild feeling to severe discomfort and varies from person to person. The mild patients need no care, but severe ones may have long hospital stay, and even suffer from multiple organ dysfunction syndrome, severely affecting postoperative rehabilitation. However, the etiology of postoperative gastrointestinal dysfunction has not been fully elucidated. Much research demonstrates that many factors, such as operative procedures, surgical operation, homeostasis disturbance, anesthesia and analgesia, blood perfusion, inflammation, and neuroendocrine factors, are responsible for the development and progression of postoperative gastrointestinal dysfunction. This study therefore reviewed the causes of postoperative gastrointestinal dysfunction in the published literatures.

Patellofemoral crepitus and clunk syndrome are infrequent, yet troublesome complications of total knee arthroplasty with a reported incidence of 0%-18%. They are primarily associated with implantation of posterior cruciate substituting designs. These entities are the result of peripatellar fibrosynovial hyperplasia at the junction of the superior pole of the patella and the distal quadriceps tendon which becomes entrapped within the superior aspect of the intercondylar box of the femoral component during knee flexion. When the knee extends, a crepitant sensation occurs as the fibrosynovial tissue exits the intercondylar box. Numerous etiologies have been proposed such as femoral component designs with a high intercondylar box ratio, previous knee surgery, reduced patellar tendon length, thinner patellar components, reduced patella-patellar component composite thickness, and smaller femoral components. Preventative measures include choice of femoral components with a reduced intercondylar box ratio, use of thicker patellar components, avoidance of over-resection of the patella, and debridement of the fibrosynovial tissue at the time of knee arthroplasty. Most patients with crepitus are unaware of the problem or have minimal symptoms so that no treatment is required. If significant disability is incurred, symptoms can be eliminated in a high percentage of patients with arthroscopic debridement of the fibrosynovial hyperplasia.

OBJECTIVETo study the clinical effects of surgical treatment of displaced intra-articular fractures of the calcaneus in elderly patients, and to discuss the operative indications.

METHODSFrom January 2000 to December 2007, 24 elderly patients with 26 fractures underwent open reduction and internal fixation for a displaced intra-articular fracture of calcaneus, which included 18 feet of 18 males and 8 feet of 6 female, with an average age of 67 years (range, 60 to 75 years). According to Sanders classification based on CT scanning, 13 fractures were rated as type II, 12 as type III and 1 as type IV. Böhler angle and Gissane angle were measured preoperatively and postoperatively and foot function was assessed with Maryland foot score system.

RESULTSTwenty-four cases with 26 feet were followed up for an average of 18.4 months (range, 12 to 26 months). Mean Böhler angle was (10.4 +/- 8.2) degrees preoperatively and (27.8 +/- 7.4) degrees postoperatively and mean Gissane angle was (136.5 +/- 10.3) degrees preoperatively and (124.3 +/- 4.2) degrees postoperatively. The difference between preoperative and postoperative values was found with statistically significant (P < 0.05). The results were excellent in 5 feet, good in 16 feet, fair in 4 feet and poor in 1 foot. There were 3 cases of wound necerosis, 2 cases of wound infection, 1 case of sural nerve injury and 6 cases of posttraumatic subtalar arthritis complications.

CONCLUSIONGood clinical result could be obtained with surgical treatment in elderly patients with displaced intra-articular fractures of the calcaneus. Open reduction appears to be an acceptable method of treatment for displaced calcaneal fractures in elderly patients if they have good general conditions.

OBJECTIVETo investigate the clinical value of T shape approach in the treatment of proximal tibial fractures.

METHODSOne handrend and thirteen patients of proximal tibial fractures were randomly divided into two groups. Group A: 62 cases underwent the traditional exposure approach. According to Schatzker classification,the cases of II to VI type was 25, 10, 16, 6, 5 respectively. Group B:51 cases underwent T shape approach ahead of knee joint, the cases of II to VI type was 21, 8, 13, 5, 4 respectively. All data were analyzed by SPSS 10.0 to compare operation time, blood loss, duration of hospitalization, healing time, the time of osseous union and complications after operation.

RESULTSSixty patients in group A and 50 patients in group B were followed-up from 12 to 24 months. (1) Operation time:group B was longer than A (P < 0.01). (2) Mean blood loss and duration of hospitalization was the same. (3) Clinical healing time:group B was shorter. (4) Mean time of osseous union: 48 group B was shorter. Function of knee: group B was better than group A. (Complication: group B was less than group A.

CONCLUSIONAs compared with traditional exposure approach, T shape approach of knee joint had advantages of small scar, fewer complications, faster union of fracture and earlier recovery of joint function. The approach is valuable for the treatment of proximal tibial fractures.

BACKGROUND: A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS: The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the Cochrane Library. A total of 306 articles were identified, but the animal studies, preclinical studies, and studies that reported the same results were excluded. As a result, a total of 286 articles were excluded and the remaining 20 were included in the final assessment. Two assessors independently extracted data from these articles using predetermined selection criteria. Qualities of the articles included were assessed using Scottish Intercollegiate Guidelines Network (SIGN). RESULTS: The complication rate of interspinous dynamic stabilization has been reported to be 0% to 32.3% in 3- to 41-month follow-up studies. The complication rate of combined interspinous dynamic stabilization and decompression treatment (32.3%) was greater than that of decompression alone (6.5%), but no complication that significantly affected treatment results was found. Interspinous dynamic stabilization produced slightly better clinical outcomes than conservative treatments for spinal stenosis. Good outcomes were also obtained in single-group studies. No significant difference in treatment outcomes was found, and the studies compared interspinous dynamic stabilization with decompression or fusion alone. CONCLUSIONS: No particular problem was found regarding the safety of the technique. Its clinical outcomes were similar to those of conventional techniques, and no additional clinical advantage could be attributed to interspinous dynamic stabilization. However, few studies have been conducted on the long-term efficacy of interspinous dynamic stabilization. Thus, the authors suggest further clinical studies be conducted to validate the theoretical advantages and clinical efficacy of this technique.

Chronic radiation enteritis(CRE) is a common complication after pelvic radiotherapy, which severely affects patients' quality of life. Surgical treatment of CRE is challenging both for surgical skills and perioperative treatment strategy. Proper preoperative nutrition support therapy can reduce the morbidity of postoperative complication and the use of stoma, while postoperative nutrition support therapy can avoid the intestinal failure. Enteral nutrition should be the primary route of perioperative nutrition support therapy in CRE as possible. Pharmaconutrients aiming at intestinal commensal microbiota and its metabolites may play a role in the management of radiation enteritis.
