PURPOSE: To assess the feasibility of transanal total mesorectal excision in difficult cases including obese patients or patients with bulky tumors or threatened mesorectal fascias. METHODS: We performed laparoscopy-assisted transanal total mesorectal excision in patients with biopsy-proven rectal adenocarcinoma located 3–12 cm from the anal verge as part of a prospective, single arm, pilot trial. The primary endpoint was resection quality and circumferential resection margin involvement. Secondary endpoints included the number of harvested lymph nodes and 30-day postoperative complications. RESULTS: A total of 12 patients (9 men and 3 women) were enrolled: one obese patient, 7 with large tumors and 8 with threatened mesorectal fascias (4 patients had multiple indications). Tumors were located a median of 5.5 cm from the anal verge, and all patients received preoperative chemoradiotherapy. Median operating time was 191 minutes, and there were no intraoperative complications. One patient needed conversion to open surgery for ureterocystostomy after en bloc resection. Complete or near-complete excision and negative circumferential resection margins were achieved in all cases. The median number of harvested lymph nodes was 15.5. There was no postoperative mortality and 3 cases of postoperative morbidity (1 postoperative ileus, 1 wound problem near the stoma site, and 1 anastomotic dehiscence). CONCLUSION: This pilot study showed that transanal total mesorectal excision is also feasible in difficult laparoscopic cases such as in obese patients or those with bulky tumors or tumors threatening the mesorectal fascia. Additional larger studies are needed.

PURPOSE: Pancreatic trauma is infrequent because of its central, deep anatomical position. This contributes to a lack of surgeon experience and many debates exist about its standard care. This study aimed to investigate the postoperative pancreatic fistula (POPF) and mortality of pancreatic trauma after operation. METHODS: We reviewed records in the trauma registry of our institution submitted from January 2006 to December 2016. The grade of pancreatic injury, surgical management, morbidity, mortality, and other clinical variables included in the analyses. RESULTS: Data from a total of 26,072 trauma patients admitted to the Emergency Department were analyzed. Pancreatic trauma was observed in 114 of these patients (0.44%). Laparotomy was performed in 81 patients (2 pan creatico duodenectomies, 2 pancreaticogastrostomies, peripancreatic drainage in 41 patients, distal pancreatectomies in 34 patients, and 9 patients who underwent surgery for damage control). The incidence of POPF was 38.3%. The overall mortality was 8.8% (7 of 81). In multivariate analysis, pancreas injury grade IV (≥4) (adjusted odds ratio [AOR], 4.071; P = 0.029) and preoperative peritonitis signs (AOR, 2.903; P = 0.039) were independent risk factors for POPF. All patients who died had also another major abdominal injury (≥grade 3). Multiorgan failure was a major cause of death (6 of 7, 85.7%). The mortality rate of isolated pancreas injury was 0%. CONCLUSION: The pancreas injury grade and preoperative peritonitis were significant risk factors of POPF. The mortality rate of isolated pancreatic trauma was very low.

STUDY DESIGN: Cross sectional study. PURPOSE: To characterize the pattern of injury, describe the current clinical management, and determine the outcomes in traumatic spine injury (TSI) patients presenting to a major government hospital in Phnom Penh, Cambodia. OVERVIEW OF LITERATURE: There is a paucity of literature on epidemiology or current clinical practices for TSIs in Cambodia. The findings from this study can thus serve as a valuable resource for future progress in treating TSIs in low-income countries. METHODS: This study was a cross-sectional study of TSI patients admitted to Preah Kossamak Hospital in Phnom Penh, Cambodia. Demographics, cause of spinal injury, spinal level of injury, surgical procedures and techniques, complications, and American Spinal Injury Association (ASIA) grades were recorded and analyzed. RESULTS: Eighty patients were admitted with TSI between October 2013 and June 2014. Falls from heights were the most common cause of TSI, followed by road traffic accidents. 78% of the admitted patients underwent at least one surgical procedure. Without intraoperative imaging, 4 patients (6%) had wrong level surgery, and 1 patient (2%) had misplacement of pedicle screws. Sacral decubitus ulcers were the most common non-surgically related complication. Antibiotics were administered to >90% of patients. There were no in-hospital mortalities. Of the 60 spinal cord injury (SCI) patients, 32% (19/60) showed improvement in their ASIA grade at the time of discharge, and 52% (31/60) showed no change. At follow-up, 32% (19/60) of SCI patients reported improvement, and 8% (5/60) reported no change. However, 36 SCI patients (60%) were lost to follow-up. CONCLUSIONS: Despite technological limitations, outcomes of TSI patients in Cambodia appear favorable with evidence of clinical improvement and low mortality.

PURPOSE: The aim of this study is to investigate the impact of age on short-term outcomes after colorectal surgery in terms of the 30-day postoperative morbidity and mortality rates. METHODS: The subjects for the study were patients who had undergone colorectal surgery. Patients were divided into 2 groups according to age; groups A and B patients were ≥80 and <80 years old of age, respectively. Both groups were manually matched for body mass index, American Society of Anesthesiologists score, Charlson Comorbidity Index and procedure performed. RESULTS: A total of 200 patients, 91 men (45.5%) and 109 women (54.5%), were included in this retrospective study. These patients were equally divided into 2 groups. The mean ages were 85 years in group A (range, 80 to 104 years) and 55.3 years in group B (range, 13 to 79 years). The overall 30-day postoperative mortality rate was 1% of total 200 patients; both of these 2 patients were in group A. However, this observation had no statistical significance. No intraoperative complications were encountered in either group. The overall 30-day postoperative morbidity rate was 27% (54 of 200) for both groups. The 30-day postoperative morbidity rates in groups A and B were 28% (28 of 100) and 26% (26 of 100), respectively. However, these differences between the groups had no statistical significance importance. CONCLUSION: Age alone should not be considered to be more of a contraindication or a worse predictor than other factors for the outcome after colorectal surgery on elderly patients.

To analyze two common factors for perioperative ischemic stroke in patients with concomitant carotid and coronary artery severe stenosis and to improve the therapeutic effect.
Methods: A total of 44 patients with multi-vessel coronary artery disease combined with carotid stenosis, who admitted to the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University from 2008 to 2014, were enrolled in this study. Among them, 32 cases were male, 12 cases was female. All patients received coronary artery bypass grafting after treatment of neck diseases. The surgical outcomes and follow-up results were analyzed retrospectively.
Results: One patient received carotid endarterectomy suffered hemiplegia, whose symptoms were improved after positive clinical treatment. One patient suffered transient ischemic attack, and 5 patients displayed the cerebrovascular syndromes a week later after surgery. Twelve patients suffered nerve function damage 48 hours later after surgery. Nine patients received intra-aortic ballon pump, 1 patient received thoracotomy hemostasis, 3 patients suffered sternal dehiscence; 27 patients showed atrial fibrillation. Two patients died after surgery. The follow-up duration ranged from 1-7 years and the follow-up rate was 90%. The ischemic symptoms were improved in 44 patients. Six patients complained the recurrence of angina, but no abnormalities were found in coronary angiography or computed tomography angiography. One patient died of malignant tumor during the follow-up duration.
Conclusion: For patients with concomitant carotid and coronary artery severe stenosis, it is more likely to suffer ischemic cerebral stroke. However, carotid stenosis is not the only factor, other key factors relevant to ischemic cerebral stroke shouldn't be ignored either.

Journal of the Korean Geriatrics Society 2015;19(1):9-15
BACKGROUND: The number of elderly patients undergoing surgery is steadily growing. Therefore, this study was designed to determine the prevalence and predictors of postoperative complications in patients older than 80 years. METHODS: The medical records of 532 patients above 80 years in age who underwent elective or emergent noncardiac surgery between June 2011 and May 2013 were reviewed retrospectively. Preoperative concomitant disease, operation site, anesthetic technique, and postoperative complications were analyzed. RESULTS: A total of 81.4% of the patients had pre-existing concomitant diseases, while 22.9% had severe systemic diseases. The incidence of severe complications within the first month after operation was 4.1%, and the in-hospital mortality rate was 1.3%. Among the severe postoperative complications, respiratory and cardiovascular complications were commonly observed. In multivariate logistic regression analysis, the predictors of postoperative severe complications included American Society of Anesthesiologists physical status classification of 3 or greater (odds ratio [OR], 5.271; 95% confidence interval [CI], 2.019-13.758; p=0.001), neurosurgery (OR, 23.132; 95% CI, 2.528-211.707; p=0.005) and duration of operation (OR, 1.006; 95% CI, 1.001-1.012; p=0.027). CONCLUSION: Proper preoperative evaluation and appropriate treatment for age-related concomitant diseases are suggested for patients older than 80 years in order to reduce postoperative complications. After operation, the respiratory and cardiovascular systems should be carefully monitored.

PURPOSE: The Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) and its Portsmouth modification (P-POSSUM) are comprehensive assessment methods for evaluating patient and surgical factors widely used to predict 30-day mortality rates. In this retrospective study, we evaluated the usefulness of POSSUM and P-POSSUM in predicting 30-day mortality after intraoperative cardiac arrests in adult patients undergoing non-cardiac surgery. MATERIALS AND METHODS: Among 190486 patients who underwent anesthesia, 51 experienced intraoperative cardiac arrest as defined in our study protocol. Predicted mortality rates were calculated using POSSUM and P-POSSUM equations and were compared with actual outcomes using exponential and linear analyses. In addition, a receiver operating characteristic curve analysis was undertaken, and area-under-the-curve (AUC) values with confidence intervals (CIs) were calculated for POSSUM and P-POSSUM. RESULTS: Among the 51 patients with intraoperative cardiac arrest, 32 (62.7%) died within 30 days postoperatively. The overall predicted 30-day mortality rates using POSSUM and P-POSSUM were 65.5% and 57.5%, respectively. The observed-to-predicted (O:E) ratio for the POSSUM 30-day mortality was 1.07, with no significant difference between the observed and predicted values (chi2=4.794; p=0.779). P-POSSUM predicted mortality equally well, with an O:E ratio of 1.10 (chi2=8.905; p=0.350). AUC values (95% CI) were 0.771 (0.634-0.908) and 0.785 (0.651-0.918) for POSSUM and P-POSSUM, respectively. CONCLUSION: Both POSSUM and P-POSSUM performed well to predict overall 30-day mortality following intraoperative cardiac arrest in adults undergoing non-cardiac surgery at a university teaching hospital in Korea.

BACKGROUND: Craniofacial resection (CFR) has been regarded as a standard treatment for various tumors involving the anterior skull base. The purpose of this study was to evaluate the results of CFR for the patients with anterior skull base malignancies in our hospital. METHODS: We retrospectively analyzed 17 patients with anterior skull base malignancies treated with CFR between 2001 and 2012. Mean follow-up duration was 41 months (range, 2-103 months). RESULTS: Intracranial involvement was found in 11 patients (65%) and orbital extension in 6 patients (35%). Classical bifrontal craniotomy was combined with endoscopic endonasal approach in 14 patients and external approach in 3 patients. Vascularized flap was used for reconstruction of the anterior fossa floor in 16 patients (94%). The most common pathological type was squamous cell carcinoma (6 patients). Gross total resection was achieved in all cases. Postoperative complications developed in 4 patients (24%) and included local wound problem and brain abscess. One patient with liver cirrhosis died from unexpected varix bleeding after the operation. Although postoperative treatment, such as radiotherapy or chemotherapy, was performed in 14 patients, local recurrence was seen in 6 patients. The mean overall survival time after the operation was 69.0 months (95% confidence interval: 47.5-90.5 months) with a 1-, 2-, and 5-year survival rate of 82.3%, 76.5%, and 64.7%, respectively. Postoperative radiotherapy was found to be the powerful prognostic factor for favorable survival. CONCLUSION: Considering the higher local control rate and acceptable complication or mortality rate, CFR with adjuvant radiotherapy is a gold standard treatment option for malignant tumors involving anterior skull base, especially with extensive intracranial involvement.

PURPOSE: This study was conducted to evaluate the surgical outcomes of active infective endocarditis with aortic root abscess formation. MATERIALS AND METHODS: Between February 1999 and June 2012, 49 patients underwent surgery for active endocarditis with aortic root abscess. The infected valve was native in 29 patients and prosthetic in 20 patients. The patients' mean age was 50+/-14 years, and 36 patients were male. Surgery was urgent/emergent in 15 patients (31%). The abscess involved the aortic annulus (11), left ventricular outflow tract (18), fibrous trigone (16), and mitral annulus (4). In all patients, wide debridement of abscess and aortic valve replacement with or without patch reconstruction of aortic root or annulus was performed. RESULTS: There were 6 (12%) operative deaths. Causes of early mortality were sepsis (2) and multi-organ failure (4). On postoperative echocardiogram, there was significant improvement of left ventricular dimension (LVEDD, from 58.8+/-11.8 mm to 52.6+/-8.2 mm, p<0.001); however, LV ejection fraction was significantly decreased (from 61.4+/-12.0% to 49.8+/-16.5%, p<0.001). The mean follow-up duration was 68.7+/-40.4 months. There was no late death or recurrent endocarditis during follow up. New York Heart Association functional class significantly improved from 3.2+/-0.7 to 1.2+/-0.4 (p<0.001). Kaplan-Meier estimated survival at 10 years was 87.2%. CONCLUSION: Surgical treatment for active endocarditis with aortic root abscess is still challenging, and was associated with high operative mortality. Nevertheless, long-term survival was excellent with good functional capacity after recovery from the early postoperative period.

Journal of Forensic Medicine 2013;29(3):193-195
OBJECTIVE:
To explore the general characteristics of medical negligence in surgery in order to provide the reference for forensic practices.
METHODS:
One hundred and twelve cases of medical negligence in surgical department were retrospectively analyzed in Fada Institute of Forensic Medicine and Science from 2008 to 2010.
RESULTS:
The common types of medical negligence cases in the surgery were improper operation procedure (28.57%), failure of consent (26.79%), and inadequate monitoring (22.32%). The results of complications included disability or functional impairment (61.61%), death (31.25%) and transient impairment with no obvious adverse reactions (7.14%). The most common roles played by the medical negligence cases were minor role (26.79%), equal role (19.64%), and slight role (14.29%).
CONCLUSION
Significant attention should be paid to the operation procedure, consent, and monitoring. It should be cautious to not make assessment on involvement degree of medical negligence.
