ABSTRACT
BACKGROUND: Groin ultrasonography (US) has been used as an adjunct to inguinal hernia diagnosis, but there is limited evidence as to whether its use affects surgical decision-making. The primary aim of this study was to examine whether groin US affects surgical management of inguinal hernia; the secondary goal was to estimate the frequency of groin US ordered before surgical consultation. METHODS: We performed a retrospective chart review of 400 consecutive patients aged older than 18 years referred to 1 of 4 general surgeons in Calgary, Alberta, for inguinal hernia between January 2014 and January 2015. Bilateral groin examinations were entered as separate entries into the database. Outcomes assessed included the frequency of groin US examinations performed within 1 year before the general surgery consultation, presence of inguinal hernia on clinical examination (CE), presence of inguinal hernia on groin US, and whether the hernia proceeded to herniorrhaphy. RESULTS: A total of 476 groins in the 400 patients (354 [88.5%] male; mean age 53.5 yr [standard deviation 15.2 yr]) were evaluated for a hernia during the study period. Groin US was performed before general surgery consultation in 336 cases (70.6%). Overall, 364 (76.5%) of the hernias were clinically palpable; of the 364, 220 (60.4%) had preconsultation US, even in the presence of a positive CE finding. Of the 112 groins that did not have a clinically palpable hernia, 103 (92.0%) underwent preconsultation US. Of the 476 groins, 315 (66.2%) underwent inguinal hernia repair: 310 (85.2%) of the 364 with clinically palpable hernias and 5 (4.8%) of the 103 with clinically negative findings but positive groin US findings. Surgical decision-making based on CE findings occurred in 390 cases (81.9%) overall, whereas surgery based on groin US findings alone occurred in 5 of 336 cases (1.5%). CONCLUSION: Routine groin US was frequently performed before general surgery consultation, whether a hernia was detectable on clinical examination or not. Positive groin US results alone infrequently affected whether the patient proceeded to surgery. Clinical examination findings played a larger role in surgical decision-making than groin US results. Eliminating the practice of routine groin US may provide considerable health care cost savings.

INTRODUCTION: Bariatric surgery has been shown to be a safe and durable intervention for patients struggling with obesity and metabolic syndrome, including hypertension. Buchwald et al. reported hypertension resolution rates in 67.1% and improvement in 78.5% following aggregate bariatric surgery. The laparoscopic sleeve gastrectomy (LSG) is becoming increasingly utilized as a primary bariatric surgery, but lacks long-term outcome data. There are a growing number of studies reporting outcome data beyond 5 years. OBJECTIVE: This study aims to systematically evaluate the efficacy of laparoscopic sleeve gastrectomy on hypertension amongst obese patients. MATERIALS AND METHODS: A comprehensive literature search was conducted through Medline, Embase, Scopus, Web of Science, Dare, Cochrane library, and HTA database. The search terms used were broad: sleeve gastrectomy AND hypertension OR blood pressure. Adult patients undergoing LSG with follow-up hypertension outcome results of at least 5 years were included. Revisional surgeries were excluded. Two independent reviewers were used. RESULTS: Fourteen studies were included in this systematic review, which included 3550 subjects in total. Mean age was 41.1 ± 10.7 years. Mean pre-operative BMI and weight were 47.7 ± 8.83 kg/m2 and 272.8 ± 48.4 lb, respectively. Pre-operative prevalence of hypertension was 36.5% (range 6.7-91%) which dropped to 14.79% (range 0-33.3%) at approximately 5-year follow-up. Hypertension resolved in 62.17% (range 0-100%) of patients and improved in 35.7% (range 13.3-76.9%) at a mean of 5.35 years of follow-up. CONCLUSION: From this systematic review, LSG is an effective intervention for bariatric patients with hypertension. In addition to the observed reduction in the incidence of hypertension, it is likely that LSG may lead to additional health system benefits such as cost savings due to reductions in antihypertensive medications. Further prospective studies should include estimates of cost savings associated with reductions in chronic antihypertensive medication usage.

BACKGROUND: Emergency general surgery (EGS) services are gaining popularity in Canada as systems-based approaches to surgical emergencies. Despite the high volume, acuity and complexity of the patient populations served by EGS services, little has been reported about the services' structure, processes, case mix or outcomes. This study begins a national surveillance effort to define and advance surgical quality in an important and diverse surgical population. METHODS: A national cross-sectional study of EGS services was conducted during a 24-hour period in January 2017 at 14 hospitals across 7 Canadian provinces recruited through the Canadian Association of General Surgeons Acute Care Committee. Patients admitted to the EGS service, new consultations and off-service patients being followed by the EGS service during the study period were included. Patient demographic information and data on operations, procedures and complications were collected. RESULTS: Twelve sites reported resident coverage. Most services did not include trauma. Ten sites had protected operating room time. Overall, 393 patient encounters occurred during the study period (195/386 [50.5%] operative and 191/386 [49.5%] nonoperative), with a mean of 3.8 operations per service. The patient population was complex, with 136 patients (34.6%) having more than 3 comorbidities. There was a wide case mix, including gallbladder disease (69 cases [17.8%]) and appendiceal disease (31 [8.0%]) as well as complex emergencies, such as obstruction (56 [14.5%]) and perforation (23 [5.9%]). CONCLUSION: The characteristics and case mix of these Canadian EGS services are heterogeneous, but all services are busy and provide comprehensive operative and nonoperative care to acutely ill patients with high levels of comorbidity.
CONTEXTE: Les services de chirurgie générale d'urgence (CGU) gagnent en popularité au Canada en tant qu'approches systémiques aux urgences chirurgicales. Malgré le volume élevé, le caractère urgent et la complexité des populations de patients desservies en CGU, peu de rapports ont porté sur la structure, les processus, les clientèles ou les résultats de ces services. La présente étude instaure une démarche de surveillance nationale qui servira à définir et à améliorer la qualité des chirurgies destinées à cette population importante et hétérogène. MÉTHODES: Une étude transversale nationale sur les services de CGU a été réalisée sur une période de 24 heures en janvier 2017 dans 14 hôpitaux de 7 provinces canadiennes recrutés par l'entremise du comité pour les soins aigus de l'Association canadienne des chirurgiens généraux. On y a inclus les patients admis dans les services de CGU, les nouvelles consultations et les patients de l'extérieur suivis par les services de CGU pendant la période de l'étude. On a recueilli les caractéristiques démographiques des patients et les données sur les interventions, les procédures et les complications. RÉSULTATS: Douze sites ont fait état de la couverture assurée par les résidents. La plupart des services ont exclu la traumatologie. Dix sites disposaient de temps protégé au bloc opératoire. En tout, 393 rencontres avec des patients ont eu lieu pendant la période de l'étude (195/386 [50,4 %] chirurgicales, 191/386 [49,5 %] non chirurgicales), avec une moyenne de 3,8 chirurgies par service. La population regroupait des cas complexes : 136 patients (34,6 %) présentaient plus de 3 comorbidités. La clientèle était diversifiée et comprenait des cas de maladie de la vésicule biliaire (69 cas [17,8â¯%]) et de l'appendice (31 [8,0 %]), de même que des situations d'urgence délicates, telle qu'obstruction (56 [14,5 %]) et perforation (23 [5,9 %]). CONCLUSION: Leurs caractéristiques et leurs clientèles sont hétérogènes, mais les services de CGU sont tous achalandés et ils offrent tous des soins chirurgicaux et non chirurgicaux complets à des patients gravement malades porteurs d'importantes comorbidités.

BACKGROUND: Athletes often use video to improve their technique. We hypothesized that surgical novices given feedback using video-replay would outperform surgical novices given verbal feedback in the performance of a laparoscopic task. METHODS: Our study used a prospective, randomized control design. The surgical task involved the laparoscopic dissection of a pig gallbladder. Our participants performed a dissection, pre- and post-traditional or video feedback. Each recording was independently scored by two staff surgeons using the previously validated rating tools. RESULTS: There was no significant difference between video feedback or traditional feedback groups in their mean overall or task specific scores. Both traditional and video-feedback groups had a trend towards improved performance post-feedback. CONCLUSIONS: No significant difference in performance by both our global assessment metrics or task-specific metrics was observed. Video feedback requires further study to investigate its impact on surgical training.

Older models of intragastric balloons (IGBs) had unacceptably high complication rates and inconsequential weight loss. With FDA approval of newer models, we aimed to systematically examine the literature regarding the efficacy of IGB therapy for obesity. A comprehensive electronic database search was completed. Title searching was restricted to the following keywords: bariatric, gastric, gastric bypass, gastric band, sleeve gastrectomy, and intragastric balloon. Twenty-six primary studies (n = 6101) were included. At balloon removal, mean change in weight and BMI were 15.7 ± 5.3 kg and 5.9 ± 1.0 kg/m(2). The most common complications were nausea/vomiting (23.3 %) and abdominal pain (19.9 %). Serious complications were rare: mortality (0.05 %) and gastric perforation (0.1 %). IGBs are associated with marked short-term weight loss with limited serious complications.

BACKGROUND: Laparoscopic splenectomy (LS) has become a safe and feasible procedure for cases involving spleens of normal size. Only a few publications report on the outcome of LS with preoperative splenic artery embolization (SAE) for massive splenomegaly. The authors present their experience in patients with massive splenomegaly who underwent laparoscopic-assisted splenectomy (LAS) or hand-assisted laparoscopic splenectomy (HALS) following SAE. METHODS: A retrospective review of patients with massive splenomegaly undergoing LAS or HALS after preoperative SAE during the years 2004 to 2006 at the authors' institution was performed. Patients with a craniocaudal spleen length of 20 cm or greater were included in the study irrespective of their primary diagnosis. The data collected included information on patient demographics, operative details, rates of conversion to open procedures, perioperative blood transfusions, and postoperative complications. Routine Doppler ultrasound of the abdomen was performed on postoperative days 7 and 30 to screen for portal vein thrombosis (PVT). RESULTS: A total of 19 patients were identified. The median spleen length was 23 cm, and the median spleen weight was 1,740 g. Nine patients underwent LAS, and 10 underwent HALS. The median operative time was 130 min, and the median hospital stay was 6 days. There were no conversions to open laparotomy. The median estimated blood loss was 200 ml. One patient required reoperation 24 h after LAS due to bleeding, and PVT developed in three patients postoperatively. CONCLUSIONS: In the setting of massive splenomegaly, LAS or HALS with preoperative SAE is safe and has a low conversion rate. Postoperative imaging surveillance for PVT should be performed routinely in this patient population.

INTRODUCTION: Surgical stapling devices have been used for a variety of purposes in both laparoscopic and open surgery. Nevertheless, trainees rarely receive any focused instruction on their application and use. This study attempts to determine the baseline knowledge of surgical stapling devices possessed by surgical residents. Furthermore, we attempt to evaluate the effectiveness of a short didactic session in improving the trainee's knowledge of the use and function of surgical staplers. METHODS: A 20-question multiple-choice test was created to evaluate a general surgery resident's knowledge on the design and use of circular, linear, and laparoscopic surgical staplers. The test was administered before and after attending a 40-minute instructional session on surgical stapling devices. The tests were then scored by a data analyst. RESULTS: A total of 26 residents of 39 in the residency program (26/39, 67%) participated. The pretest mean was 10.62/20 (53%), whereas the posttest mean was 15.38/20 (77%). These results were significantly different on paired samples t-test analysis (t((25)) = -10.3; p < 0.05). The mean pretest scores were also significantly different between resident levels (R1-R2, 9.50; R3-R5, 11.31; t((24)) = -2.10; p < 0.05). Senior-level residents scored higher on posttest analysis, but this result was not significant (R1-R2, 14.70; R3-R5, 15.81; t((24)) = -1.63; p > 0.05). DISCUSSION: There is a deficiency of knowledge of surgical staplers in general surgery residents, more so in junior residents. Didactic instruction is effective in raising the level of knowledge of surgical staplers in all residents, up to a similar level. Surgical educators should consider implementing programs like these for staplers and other types of surgical equipment.

BACKGROUND: Transarterial chemoembolization (TACE) is a well accepted treatment for inoperable hepatocellular carcinoma (HCC). While minor complications involve 10% of all patients, severe complications are rare. CASE PRESENTATION: We describe a case of a 90-year-old male with a large, superficial HCC who underwent TACE. He had a significant intraperitoneal bleed secondary to tumor rupture immediately following the procedure. CONCLUSION: Tumor size and superficial location must be considered risk factors for tumor rupture and related complications.
