For elective surgery of colorectal cancer, current evidence supports preoperative mechanical bowel preparation combined with oral antibiotics. Meanwhile, for patients with varied degrees of intestinal stenosis, individualized protocol is required to avoid adverse events. We hereby summarize recent high-quality evidences and updates of guidelines and consensus, and recommend stratified bowel preparation based on the clinical practice of our institute as follows. (1) For patients with unimpaired oral intake, whose tumor can be passed by colonoscopy, mechanical bowel preparation and oral antibiotics are given. (2) For patients without symptoms of bowel obstruction but with impaired oral intake or incomplete colonoscopy due to tumor-related stenosis, small-dosage laxative is given for several days before surgery, and oral antibiotics the day before surgery. (3) For patients with bowel obstruction, mechanical bowel preparation or enema is not indicated. We proposed this evidence-based, individualized protocol for preoperative bowel preparation for the reference of our colleagues, in the hope of improving perioperative outcomes and reducing adverse events.

At present, nasal abnormalities is often classified from different perspectives, such as the alar-columella relationship, nasal base width, and the condition of alar hyperplasia. However, due to the impact of race and region, different people may be applied to different classification methods, resulting in different clinical diagnosis and treatments. So far, there is no unified standard for alar deformity classification to guide clinical treatment. In alar-columella relationship, the retracted ala and the hanging columella, hanging ala and retracted columella are easily confused. According to the classification of nasal base width, it is easy to confuse the alar flare with wide alar base. Therefore, the accurate preoperative evaluation of the nasal ala and the selection of appropriate clinical treatments for different abnormalities are beneficial for surgeons to achieve perfect rhinoplasty results.

The opioid epidemic continues to be a serious public health concern. Many have pointed to prescription drug misuse as a nidus for patients to become addicted to opioids and as such, urologists and other surgical subspecialists must critically define optimal pain management for the various procedures performed within their respective disciplines. Controlling pain following penile prosthesis implantation remains a unique challenge for urologists, given the increased pain patients commonly experience in the postoperative setting. Although most of the existing urological literature focuses on interventions performed in the operating room, there are many studies that examine the role of preoperative adjunctive pain medicine in diminishing postoperative narcotic requirements. There are relatively few studies looking at postoperative strategies for managing pain in prosthetic surgery with follow-up past the immediate hospitalization. This review assess the various strategies employed for managing pain following penile implantation through the lens of the current state of the opioid crisis, thus examining how urologists can responsibly treat pain without contributing to the growing threat of opioid addiction.

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

OBJECTIVE: To investigate the evaluation value of preoperative peripheral blood lymphocyte-to-monocyte ratio (LMR) on the prognosis of patients with stage III colon cancer undergoing radical resection and postoperative adjuvant chemotherapy. METHODS: Electronic medical record were retrospectively retrived for stage III colon cancer patients who underwent radical surgery at Sun Yat-sen University Cancer Center from December 2007 to December 2013. Inclusion criteria were pathologically comfirmed colon adenocarcinoma, complete clinicopathological data, and postoperative XELOX (oxaliplatin + capecitabine) chemotherapy with follow-up of at least 3 months. Patients with neoadjuvant anti-tumor therapy, infectious disease, other malignant tumors and death of non-tumor causes within 3 months after operation were excluded. A total of 258 patients were included in this retrospective cohort study, including 146 males and 112 females with median age of 55 (22 to 85) years. Tumors of 100(38.8%) patients were located in the right hemicolon, and of 158 (61.2%) in the left hemicolon. Tumors of 194(75.2%) patients were highly and moderately differentiated, and of 64 (24.8%) were poorly differentiated. According to the TNM tumor pathological stage of AJCC 7th edition, 196 (76.0%) patients were stage IIIA to IIIB, and 62(24.0%) patients were stage IIIC. The median preoperative CEA was 3.8 (0.3 to 287.5) μg /L and the median cycle of the adjuvant chemotherapy was 6 (1 to 8). The cut-off value of preoperative LMR in prediction of 3-year overall survival (OS) outcome was determined by receiver operating characteristic (ROC) curve analysis. All patients were divided into low LMR group and high LMR group according to the critical value. Clinicopathological characteristics between the two groups were compared by using chi-square test or Fisher's exact test as appropriate. The 3-year disease-free survival and overall survival rate were estimated with the Kaplan-Meier method, and differences between two groups were assessed with the log-rank test. Univariate and multivariate analyses were performed through Cox regression model. RESULTS: ROC curve showed that the cut-off value of preoperative LMR in predicting 3-year overall survival was 4.29. Then 143 patients were divided into low LMR group (LMR<4.29) and 115 patients into high LMR group (LMR ≥ 4.29). Compared with high LMR group, the low LMR group presented higher proportions of male [62.2%(89/143) vs. 50.4%(58/115), χ²=4.167, P=0.041], right hemicolon cancer [44.8% (64/143) vs. 31.3% (36/115), χ²=4.858, P=0.028], and the largest tumor diameter>4 cm [60.1% (86/143) vs. 33.0% (38/115), χ²=18.748, P<0.001]. During a median follow-up of 46.0 (range, 3.0 to 74.0) months, 3-year disease-free survival rate was 83.8% in high LMR group and 78.9% in low LMR group, which was not significantly different (P=0.210). While 3-year overall survival rate in low LMR group was significant lower than that in high LMR group (86.6% vs. 97.2%, P=0.018). Univariate analysis revealed that preoperative low LMR (HR=2.841, 95%CI: 1.146 to 7.043, P=0.024), right hemicolon cancer (HR=2.865, 95%CI: 1.312 to 6.258, P=0.008) and postoperative adjuvant chemotherapy≥6 cycles (HR=0.420, 95%CI: 0.188 to 0.935, P=0.034) were the risk factors for poor overall survival. Multivariate analysis identified that preoperative low LMR (HR=2.550, 95%CI: 1.024 to 6.347, P=0.004) and right hemicolon cancer (HR=2.611, 95%CI: 1.191 to 5.723, P=0.017) were the independent risk factors for overall survival. CONCLUSIONS Preoperative peripheral blood LMR level represents an effective prognostic predictor for patients with stage III colon cancer receiving radical therapy. Low LMR indicates the poor prognosis and such patients require aggressive postoperative treatment strategy.

It is necessary to organize and arrange the hair before performing surgery on the scalp. The hair is preserved in most cases, and the remaining hair makes it difficult to apply and maintain the drape. Moreover, hair that has not been properly sterilized can be a risk factor for infection. Accordingly, the authors of the present study benchmarked a method of hair control within the operative field using a sterile gel. Prior to surgery, the hair around the lesion can be organized and rearranged to the desired shape by using a sterile medical gel as a hairstyling product. Subsequently, chlorhexidine-isopropyl alcohol can be used for aseptic skin preparation, followed by draping for surgery. By controlling the hair using this method, hair can be prevented from falling into the operative field, thereby reducing the risk of surgical site infection.

The anastomotic complications following radical gastrectomy mainly include anastomotic leakage, anastomotic hemorrhage, and anastomotic stricture. Theanastomotic complications are not rare and remain the most common complications resulting in the perioperativedeath of patients with gastric cancer. Standardized training could let surgeons fully realize that strict selection of operative indications, thorough preoperative assessment and preparation, and refined operation in surgery are the essential measures to prevent the anastomotic complications following radical gastrectomy. In addition, identifying these complications timely and taking effective measures promptly according to the clinical context are the keys to treating these complications, reducing the treatment cycle, and decreasing the mortality.

Enhanced recovery after surgery (ERAS) has been rapidly developing by combining several techniques with evidence-based adjustments, including preoperative education, preoperative carbohydrate loading, epidural or regional anesthesia, early initiation of enteral nutrition, ambulation and multi-modal pain management. The core part of ERAS is to reduce and reverse surgical stress and therefore greatly improve clinical outcome. Under the guidance of ERAS, perioperative management of robotic gastric cancer operation should follow the basic principles of ERAS and clinical pathway to maximize the advantages of the robotic surgery. ERAS protocol is safe and feasible for patients undergoing robotic radical gastrectomy and it can reduce surgical stress, shorten hospital stay, improve quality of life and does not increase complications, whose mechanism may be associated with the reduction of inflammation and insulin resistance, the decrease of resting energy exposure, and the protection of mitochondria function. It is worth emphasizing that it is very important to fully understand the changes of pathophysiology during perioperative period, to strictly implement the ERAS pathway based on optimized evidence-based medicine, to cooperate closely with the multidisciplinary team, to observe and manage the postoperative complications dynamically by systemic classification. The improvement of ERAS program on the outcome of patients should be summarized regularly and the new interventional strategies should be evaluated further according to the international standard.

PURPOSE: To identify and analyze the role of preoperative computed tomography (CT) in patients with tearing symptoms with nasolacrimal duct obstruction (NLDO). METHODS: We retrospectively reviewed the medical records and CT results on 218 patients who complained of tearing symptoms with NLDO between January 2014 and December 2014. All patients were recruited from Kim's Eye Hospital's outpatient clinic and assessed by clinical history, examination, and CT to evaluate periocular pathology and nasolacrimal drainage system. Patients with abnormal findings assessed by preoperative CT were further reviewed. RESULTS: CT was performed on 218 patients (average age, 58.2 ± 11.9 years). Of these, 196 (89.9%) had endonasal dacryocystorhinostomy, 14 (6.4%) declined surgery, and 8 (3.7%) were inoperable due to abnormal CT findings. Soft tissue opacity was the most common finding which 243 cases (85.9%) of 283 obstructed nasolacrimal duct and 89 cases (81.7%) of 109 non-obstructed nasolacrimal duct showed it. Thirty-nine (17.8%) of 218 patients showed either maxillary sinusitis or ethmoidal sinusitis and 32 (14.7%) of 218 patients presented with periocular inflammation. Other abnormal CT findings included septal deviations, previous fractures, masses, and structural abnormalities of nasal cavity. CONCLUSIONS: Preoperative CT imaging is useful in the assessment of both nasolacrimal drainage and nearby anatomical structures. This information will be helpful in planning surgical interventions and management of NLDO.
