    ABSTRACT: Carotid endarterectomy (CEA) is a very common operation, but there is no agreement on the appropriate orientation of the surgical incision. We retrospectively reviewed the charts of patients who had undergone CEA between Jul. 1, 2010, and Dec. 31, 2013. We contacted patients identified in the review to solicit participation in a clinical follow-up examination, during which the esthetic outcome of the scar was evaluated using the Patient and Observer Scar Assessment Scale (POSAS). During the study period 237 CEAs were performed. Nine patients refused the use of their personal health information in this study. There were no significant differences in the neurologic outcomes of patients based on the incision orientation (perioperative stroke and death 1.4% with transverse incision v. 0% with a vertical incision, p = 0.44). Fifty-two patients presented for follow-up examination. Thirty-three had a transverse incision and 19 had a vertical incision. Results of the POSAS significantly favoured the transverse incision (p = 0.03). Vertical incisions were more often associated with persistent, mild marginal mandibular nerve dysfunction (p = 0.04). Carotid endarterectomy performed through a transverse skin incision compared with a vertically oriented skin incision is associated with improved esthetic outcome, as measured by the POSAS, without an observed statistically significant difference in the risk of perioperative stroke or death between the 2 techniques.

    ABSTRACT: Door openings disrupt the laminar air flow and increase the bacterial count in the operating room (OR). We aimed to define the incidence of door openings in the OR during primary total joint arthroplasty (TJA) surgeries and determine whether measures were needed and/or possible to reduce OR staff traffic. We recorded the number of door openings during 100 primary elective TJA surgeries; the OR personnel were unaware of the observer's intention. Operating time was divided into the preincision period, defined as the time from the opening of surgical trays to skin incision, and the postincision period, defined as time from incision to dressing application. The mean number of door openings during primary TJA was 71.1 (range 35-176) with a mean operative time of 111.9 (range 53-220) minutes, for an average of 0.64 (range 0.36-1.05) door openings/min. Nursing staff were responsible for 52.2% of total door openings, followed by anesthesia staff at 23.9% and orthopedic staff at 12.7%. In the preincision period, we observed an average of 0.84 door openings/ min, with nursing and orthopedic personnel responsible for most of the door openings. The postincision period yielded an average of 0.54 door openings/min, with nursing and anesthesia personnel being responsible for most of the door openings. There is a high incidence of door openings during TJA. Because we observed a range in the number of door openings per surgery, we believe it is possible to reduce this number during TJA.

    ABSTRACT: Literature is lacking on acute surgical problems that may be encountered on military deployment; even less has been written on whether or not any of these surgical problems could have been avoided with more focused predeployment screening. We sought to determine the burden of illness attributable to acute nontraumatic general surgical problems while on deployment and to identify areas where more rigorous predeployment screening could be implemented to decrease surgical resource use for nontraumatic problems. We studied all Canadian Armed Forces (CAF) members deployed to Afghanistan between Feb. 7, 2006, and June 30, 2011, who required treatment for a nontraumatic general surgical condition. During the study period 28 990 CAF personnel deployed to Afghanistan; 373 (1.28%) were repatriated because of disease and 100 (0.34%) developed an acute general surgical condition. Among those who developed an acute surgical illness, 42 were combat personnel (42%) and 58 were support personnel (58%). Urologic diagnoses (n = 34) were the most frequent acute surgical conditions, followed by acute appendicitis (n = 18) and hernias (n = 12). We identified 5 areas where intensified predeployment screening could have potentially decreased the incidence of in-theatre acute surgical illness. Our findings suggest that there is a significant acute care surgery element encountered on combat deployment, and surgeons tasked with caring for this population should be prepared to treat these patients.

    ABSTRACT: The North Atlantic Treaty Organization (NATO) Role 3 Multinational Medical Unit (R3-MMU) is a tertiary care trauma facility that receives casualties, both coalition and civilian, and provides humanitarian medical assistance when able to the Kandahar province in southern Afghanistan. We examined the cohort of pediatric patients evaluated at the facility during a 16-month period to determine the characteristics and care requirements of this unique patient population. A database of Afghan patients younger than 18 years of age admitted to the NATO R3-MMU between January 2010 and April 2011 was developed from the Joint Theatre Trauma Registry. This patient cohort was analyzed to determine demographics, injury mechanism, injury severity, resource utilization and factors associated with mortality. A total of 263 children were admitted to the NATO R3-MMU during the study period, representing 12% of all trauma admissions during this time period. The median age was 9 years (range 3 mo-17 yr) with a predominance of male patients (82%). Battle-related trauma was responsible for 62% of admissions, with explosive blast injury constituting the predominant mechanism (42%). The average injury severity score was 12.3 ± 9.3. Overall mortality was 8%. Factors associated with increased risk of death included admission acidosis, coagulopathy, hypothermia and female sex. Children represent a significant proportion of traumatic injuries encountered in a modern war zone; many of them are critically injured. Organizations that provide health care in such environments should be prepared to care for this patient population where their mandates and facilities allow for it.

    ABSTRACT: Robotic-assisted proctectomy with coloanal anastomosis (RPCA) is an innovative technique of pelvic dissection for low rectal cancer. Our objective was to evaluate our pilot experience with this procedure compared with open proctectomy with coloanal anastomosis (OPCA). We performed a retrospective 5-year review of all consecutive cases of RPCA and OPCA performed at our institute. We focused on tumour characteristics, quality of surgery, analgesic requirements, average length of hospital stay (LOS), complications and long-term outcomes. Three patients underwent RPCA and 25 had OPCA. The average duration of surgery was similar (288 min for RPCA v. 285 min for OPCA). Four patients in the OPCA group had positive or very close margins, and 2 had a mesorectal defect less than 5 mm. The average LOS was 6.66 and 9.29 days in the RPCA and OPCA groups, respectively, and the average duration of epidural or patient-controlled anesthesia was 2.67 and 5.16 days, respectively. We did not perform a statistical comparison because of the discordant size and sex distribution between the groups. There were no perioperative complications in the RPCA group, and all patients had negative margins and adequate lymph node retrievals with no long-term complications or recurrence recorded so far. Our very early experience with RPCA is quite encouraging, suggesting that it is a safe alternative to OPCA with a similar duration and the added benefits of a minimally invasive procedure, including decreased LOS and reduced postoperative analgesic requirements.

    ABSTRACT: Computed tomography (CT) scans are commonly used to diagnose acute diverticulitis, but there are overlapping features between diverticulitis and colorectal cancer (CRC) on imaging studies. Hence, colonoscopy is typically recommended after an episode of acute diverticulitis to rule out underlying malignancy. Currently, 64-slice multidetector CT scanners are capable of providing higher-resolution images and may be able to distinguish malignancy from diverticular inflammation. We aimed to determine the prevalence of CRC among patients with CT-diagnosed acute diverticulitis. We performed a retrospective study of patients with acute diverticulitis diagnosed on CT scan between December 2005 and December 2010 at St. Paul's Hospital, Vancouver, BC. Nonresidents were excluded. We reviewed CT scan reports that included the term "diverticulitis," reports of follow-up colonic evaluation within 1 year of diagnosis and pathology results. We queried the provincial cancer registry to ensure no cases of CRC were missed. A total of 293 patients had acute diverticulitis diagnosed on CT scan, but 8 were nonresidents and were excluded. Of the 285 included in the analysis, the mean age was 59.4 ± 15.1 years, and 167 (58.6%) were men. Among the 114 patients who underwent follow-up evaluation, malignancy was diagnosed in 4 (3.5%). The overall prevalence of malignancy among patients with CT-diagnosed diverticulitis was 1.4%. Routine endoscopic evaluation after an episode of diverticulitis diagnosed with high-resolution CT scan does not appear to be necessary. Selective approach in patients with protracted clinical course or those with mass lesion/obstruction on CT scan may be of benefit.

    ABSTRACT: The lymph node ratio (LNR) has been shown to be an important prognostic factor in patients with gastric, breast, pancreatic and colorectal cancer. We investigated the prognostic impact of the LNR in addition to TNM classification in patients with locally advanced rectal cancer. We retrospectively analyzed patients who underwent curative resection for locally advanced rectal cancer between July 2005 and December 2010. We determined the LNR cutoff value using a receiver operating characteristic curve. The Kaplan-Meier method was used to estimate survival curves, while Cox regression analyses were used to evaluate the relationship between LNR and survival. We included 180 patients aged 28-83 years with median follow-up of 41.8 months. The median number of lymph nodes examined and lymph nodes involved were 11.5 and 4, respectively, and the median LNR was 0.366. An LNR of 0.19 (19%) was the cutoff point to separate patients with regard to median overall survival. Median overall survival was 64.2 months for patients with an LNR of 0, 59.1 for an LNR of 0.19 or less and 37.6 for an LNR greater than 0.19 (p = 0.004). The median disease-free survival was 32.9 months for patients with an LNR of 0, 30.4 for an LNR of 0.19 or less and 17.8 for an LNR greater than 0.19 (p = 0.002). Our results suggest that LNR should be considered an additional prognostic factor in patients with locally advanced rectal cancer.

    ABSTRACT: Nontraumatic osteonecrosis of the femoral head (ONFH) is a progressive disease in young adults producing substantial morbidity and frequently resulting in total hip arthroplasty. Although hip-preserving surgical procedures represent the current mainstay of treatment for early disease, medical therapies targeting specific pathways in the ONFH pathogenesis could help prevent disease progression while producing less morbidity. Acetylsalicylic acid (ASA) is a promising alternative to other therapies for ONFH owing to its anti-inflammatory and antithrombotic mechanisms of action and its relatively benign side effect profile. We followed a prospective cohort of 10 patients (12 hips) with precollapse ONFH who were given ASA to prevent disease progression. Their outcomes were compared with those of a historic control group taken from the literature. Progression occurred in 1 of 12 (8%) patients taking ASA compared with 30 of 45 (66.6%) controls (p = 0.002) at a mean follow-up of 3.7 years. Patients taking ASA also tended to exhibit decreased femoral head involvement at the end of therapy. This hypothesis-generating study leads us to believe that ASA may be a simple and effective treatment option for delaying disease progression in patients with early-stage ONFH.

    ABSTRACT: Point of injury needle thoracostomy (NT) for tension pneumothorax is potentially lifesaving. Recent data raised concerns regarding the efficacy of conventional NT devices. Owing to these considerations, the Israeli Defense Forces Medical Corps (IDF-MC) recently introduced a longer, wider, more durable catheter for the performance of rapid chest decompression. The present series represents the IDF-MC experience with chest decompression by NT. We reviewed the IDF trauma registry from January 1997 to October 2012 to identify all cases in which NT was attempted. During the study period a total of 111 patients underwent chest decompression by NT. Most casualties (54%) were wounded as a result of gunshot wounds (GSW); motor vehicle accidents (MVAs) were the second leading cause (16%). Most (79%) NTs were performed at the point of injury, while the rest were performed during evacuation by ambulance or helicopter (13% and 4%, respectively). Decreased breath sounds on the affected side were one of the most frequent clinical indications for NT, recorded in 28% of cases. Decreased breath sounds were more common in surviving than in nonsurviving patients. (37% v. 19%, p < 0.001). A chest tube was installed on the field in 35 patients (32%), all after NT. Standard NT has a high failure rate on the battlefield. Alternative measures for chest decompression, such as the Vygon catheter, appear to be a feasible alternative to conventional NT.
