Nonoperative management of gastrointestinal malignancies in era of neoadjuvant treatment

Cancers derived from the gastrointestinal(GI)tract are often treated with radical surgery to achieve a cure.However,recent advances in the management of GI cancers involve the use of a combination of neoadjuvant radiation and chemotherapy followed by surgical intervention to achieve improved local control and cure.Interestingly,a small proportion of patients with highly sensitive tumors achieved a pathological complete response(pCR)(no residual tumor cells in the resected specimen)to neoadjuvant chemoradiation therapy(nCRT).The desire for organ preservation and avoidance of surgical morbidity brings the idea of a nonoperative management(NOM)strategy.Because of the different nature of tumor biology,GI cancers present diverse responses to nCRT,ranging from high sensitivity(anal cancer)to low sensitivity(gastric/esophageal cancer).There is an increasing attention to NOM of localized GI cancers;however,without the use of biomarkers/imaging parameters to select such patients,NOM will remain a challenge.Therefore,this review intends to summarize some of the recent updates from the aspect of current nCRT regimens,criteria for patient selection and active surveillance schedules.We also hope to review significant sequelae of radical surgery and the complications of nCRT to clarify the directions for optimization of nCRT and NOM for oncologic outcomes and quality of life.

Pancreatic duct disruption and nonoperative management: the SEALANTS approach

Low serum albumin may predict poor efficacy in patients with perforated peptic ulcer treated nonoperatively

BACKGROUND Nonoperative management(NOM)is a promising therapeutic modality for patients with perforated peptic ulcer(PPU).However,the risk factors for poor efficacy and adverse events of NOM are a concern.AIM To investigate the factors predictive of poor efficacy and adverse events in patients with PPU treated by NOM.METHODS This retrospective case-control study enrolled 272 patients who were diagnosed with PPU and initially managed nonoperatively from January 2014 to December 2018.Of these 272 patients,50 converted to emergency surgery due to a lack of improvement(surgical group)and 222 patients were included in the NOM group.The clinical data of these patients were collected.Baseline patient characteristics and adverse outcomes were compared between the two groups.Logistic regression analysis and receiver operating characteristic curve analyses were conducted to investigate the factors predictive of poor efficacy of NOM and adverse outcomes in patients with PPU.RESULTS Adverse outcomes were observed in 71 patients(32.0%).Multivariate analyses revealed that low serum albumin level was an independent predictor for poor efficacy of NOM and adverse outcomes in patients with PPU.CONCLUSION Low serum albumin level may be used as an indicator to help predict the poor efficacy of NOM and adverse outcomes,and can be used for risk stratification in patients with PPU.

NonOperative Management of Blunt Solid Abdominal Organ Injury in Calabar, Nigeria

Background: Over the past several years, nonoperative management has been increasingly recommended for the care of selected blunt abdominal trauma patients with solid organ injuries. Objective: To evaluate the pattern and outcome of blunt abdominal trauma using haemodynamic stability and ultrasonography in the selection of patients for nonoperative management in a facility without computed tomogram. Methods: Patients admitted with blunt abdominal trauma between February 2005 and January 2010 were prospectively studied. Haemodynamic stability and sonography formed the basis for selecting patients for nonoperative management. Results: In total, 58 patients suffered blunt abdominal trauma and 19(33%) patients were successfully managed nonoperatively suffered blunt solid abdominal organ injuries. Road traffic accidents inflicted 17(89%) patients while 2(11%) patients sustained sports injury (football). The spleen was the commonest solid organ injured 12(60%), while the liver and kidney were injured in 6(30%) and 2(10%) respectively. Associated injuries were fractured left femur recorded in 3(16%) patients and fractured rib in a patient (5%). Conclusion: Nonoperative treatment is a safe and effective method in the management of haemodynamically stable patient with blunt solid abdominal organ injury. This translated to a reduction in hospital stay, absence of the risk of blood transfusion as well as attendant morbidity and mortality associated with laparotomy. Establishment of trauma system, provision of diagnostic and monitoring facilities, good roads, and education on road safety is recommended for improved outcome.

Distal radial fractures——Operative versus nonoperative treatment

There is some evidence to suggest superior results of surgical treatment that includes open reduction internal fixation (ORIF) or percutaneous pin fixation (not including Kapandji pinning) to stabilize fracture fragments and improve functional ability compared with conservative treatment. However, larger studies with longer follow up are needed to verify these results.

Role of platelet-rich plasma in the treatment of rotator cuff tendinopathy

Shoulder pain is a common musculoskeletal complaint,and rotator cuff(RC)pathologies are one of the main causes.The RC undergoes various tendinopathic and avascular changes during the aging process.Other degenerative changes affecting its healing potential make it an appealing target for biological agents.Platelet-rich plasma(PRP)has demonstrated the potential to deliver a high concentration of several growth factors and anti-inflammatory mediators,and its clinical use is mainly supported by experiments that demonstrated its positive effect on muscle,ligaments,and tendinous cells.This review aimed to specify the role of PRP and its future applications in RC tendinopathies based on the current clinical evidence.Due to the different characteristics and conflicting outcomes,clinicians should use PRP with moderate expectations until more consistent evidence is available.However,it is reasonable to consider PRP in patients with contraindications to corticosteroid injections or those with risk factors for inadequate healing.Its autologous origin makes it a safe treatment,and its characteristics make it a promising option for treating RC tendinopathy,but the efficacy has yet to be established.

Adhesive small bowel adhesions obstruction: Evolutions in diagnosis, management and prevention

Intra-abdominal adhesions following abdominal surgery represent a major unsolved problem. They are the first cause of small bowel obstruction. Diagnosis is based on clinical evaluation, water-soluble contrast followthrough and computed tomography scan. For patients presenting no signs of strangulation, peritonitis or severe intestinal impairment there is good evidence to support non-operative management. Open surgery is the preferred method for the surgical treatment of adhesive small bowel obstruction, in case of suspected strangulation or after failed conservative management, but laparoscopy is gaining widespread acceptance especially in selected group of patients. "Good" surgical technique and anti-adhesive barriers are the main current concepts of adhesion prevention. We discuss current knowledge in modern diagnosis and evolving strategies for management and prevention that are leading to stratified care for patients.

手术与非手术治疗跟骨骨折的疗效比较

[目的]探讨手术与非手术治疗跟骨骨折的疗效，便于临床选择跟骨骨折的治疗方法。[方法]总结2001年1月～2005年8月间手术治疗的跟骨骨折38例（42足），骨折类型：按Essex—Lopresti分类方法：Ⅰ型，舌形骨折6足，Ⅱ型，压缩骨折28足，Ⅲ型，严重粉碎骨折8足，手术方式均为钢板内固定（AO跟骨钢板，国产仿AO跟骨钢板），手术入路均为外侧“L”形扩大入路，术后不用石膏固定，2～3d后即行不负重功能锻炼，6～8周后逐渐负重锻炼。并与40例（42足）采用非手术方法（手法复位石膏固定、骨牵引后石膏固定）治疗的患者进行比较，所有病例随访10～36个月，平均17个月。[结果]按Maryland足部评分系统评价，并以每足为基数，手术治疗组：优良率93％，其中Ⅰ型骨折优良率为100％，Ⅱ型骨折优良率为96％，Ⅲ型骨折优良率为75％。非手术治疗组：优良率67％，其中Ⅰ型骨折优良率为92％，Ⅱ型骨折优良率为77％，Ⅲ型骨折无优良患者。[结论]跟骨骨折治疗的关键是尽可能恢复跟距、跟骰关节面的平整和跟骨的正常解剖形态。对跟骨Essex—Lopresti分类Ⅱ型和Ⅲ型骨折者，应积极采用开放复位内固定治疗，并应恰当地选择手术入路，掌握正确地骨折复位方法和术后处理。对跟骨骨折治疗方式的选择应据患者的个体状况、骨折类型等综合考虑才能达到最佳效果。
