Introduction: Recently, magnetic solutions have been proposed to minimize surgical invasiveness. These are comprised of deployable instruments containing magnets which are inserted into the abdominal cavity through a single access point. The manipulation of the internal elements occurs via magnets held on the external surface of the abdominal wall. This technology relies on the magnetic force between the magnets, which is inversely related to the abdominal wall thickness (AWT). The aim of this study was to establish the expected change in AWT from before and after initiation of pneumoperitoneum. Material and methods: Patients scheduled for laparoscopic procedures were assessed by ultrasound for AWT immediately before and during laparoscopy. Change of AWT during laparoscopy was calculated. Statistical analysis was performed using Student's t-test. Results: Thirty-two patients undergoing various laparoscopic procedures were included. Twenty patients were male (62.5%) and ten were morbidly obese (31%). Mean age was 51 years (range 18-76) and average BMI was 28.1 kg/m2 (range 19.0-41.0). AWT decreased on average by 15.6% once pneumoperitoneum was initiated in both obese and non-obese patients (p = .01). Conclusion: Our data suggest that following preoperative assessment of AWT with abdominal wall ultrasound, more patients than expected might be candidates for the use of trans-abdominal magnetic devices.

The beneficial effect of bariatric surgery (BS) in type 2 diabetes mellitus patients is well established. Conversely, little is known about the efficacy of BS in type 1 diabetes mellitus (T1DM) patients, despite the increasing prevalence of obesity in this population. A retrospective review was carried out on a prospectively collected bariatric surgery registry of all patients undergoing BS at two university hospitals between 2010 and 2015. Patients with T1DM were identified, and detailed chart reviews were obtained. In this time period, we operated on thirteen patients with T1DM. Eight were female (61.5 %). Median age at time of surgery was 38 ± 8.3 (range 28–53) years. The procedures performed were laparoscopic sleeve gastrectomy (n = 10) and laparoscopic Roux-en-Y gastric bypass (n = 3). On median postoperative follow-up of 24 (range 2.5–51) months, mean body mass index significantly decreased from 39.9 ± 4.1 to 30.1 ± 3.9 kg/m2 (P

BACKGROUND: Other than the Advanced Trauma Life Support course, usually run for postgraduate trainees, there are few trauma courses available for medical students. It has been shown that trauma teaching for medical students is sadly lacking within the undergraduate curriculum. We stated that students following formal teaching, even just theory and some practice in basic skills significantly improved their management of trauma patients. METHODS: Hadassah-Hebrew University in Israel runs an annual 2-week trauma course for final-year medical students. The focus is on hands-on practice in resuscitation, diagnosis, procedures, and decision making. After engaging a combination of instructional and interactive teaching methods including practice on simulated injuries that students must assess and treat through the 2 weeks, the course culminates in a disaster drill where students work alongside the emergency services to rescue, assess, treat, and transfer patients. The course is evaluated with a written precourse and postcourse test, an Objective Structured Clinical Examination and detailed feedback from the drill. RESULTS: We analyzed student feedback at the end of each course during a 6-year period from 2007 to 2012. Correct answers for the posttest results were higher each year with good reliability as assessed by Chronbach's α and with significant variation from pretest scores assessed using paired-samples t tests. Best scores were achieved in knowledge acquisition and practical skills gained. Students were also asked whether the course contributed to self-preparedness in treating trauma patients, and this consistently achieved high scores. CONCLUSION: We believe that students benefit substantially from the course and gain lasting skills and confidence in trauma management, decision making, and organizational skills. The course provides students with the opportunity to learn and ingrain trauma principles along Advanced Trauma Life Support guidelines and prepares them for practice as safe doctors. We advocate the global implementation of a student trauma training course as a mandatory educational initiative and propose our course format as a model for similar courses. Language: en

Introduction: Rectovaginal fistulas are a relatively rare, but debilitating condition which pose a significant treatment challenge.Areas covered: In this manuscript we discuss the etiology, classification as well as the manifestations and evaluation of rectovaginal fistulas. We summarize the different surgical techniques and evaluate their success rates and perioperative considerations according to cited sources.Expert commentary: A deep understanding of the disease, treatment options, and familiarity with the different surgical treatment options available is mandatory for choosing the correct treatment. When the surgical treatment is tailored to the specific fistula and patient, many patients can eventually have successful resolution. This review will address the management and patient outcomes after treatment for rectovaginal fistulas.

In recent years, single-port laparoscopy (SPL) has become an attractive approach for performing surgical procedures. The pitfalls of this approach are technical and financial. Financial concerns are due to the increased cost of dedicated devices and prolonged operating room time. Our aim was to calculate the cost of SPL using a reusable port and instruments in order to evaluate the cost difference between this approach to SPL using the available disposable ports and standard laparoscopy. We performed 22 laparoscopic procedures via the SPL approach using a reusable single-port access system and reusable laparoscopic instruments. These included 17 cholecystectomies and five other procedures. Operative time, postoperative length of stay (LOS) and complications were prospectively recorded and were compared with similar data from our SPL database. Student’s t test was used for statistical analysis. SPL was successfully performed in all cases. Mean operative time for cholecystectomy was 72 min (range 40–116). Postoperative LOS was not changed from our standard protocols and was 1.1 days for cholecystectomy. The postoperative course was within normal limits for all patients and perioperative morbidity was recorded. Both operative time and length of hospital stay were shorter for the 17 patients who underwent cholecystectomy using a reusable port than for the matched previous 17 SPL cholecystectomies we performed (p

Background: The recent growth in the volume of civilian blast trauma caused by terrorist bombings warrants special attention to the specific pattern of injury associated with such attacks. Objective: To characterize the abdominal injuries inflicted by terrorist-related explosions and to compare the pattern of injury with civilian, penetrating and blunt, abdominal trauma. Methods: Retrospective analysis of prospectively collected data from 181 patients with abdominal trauma requiring laparotomy, who were admitted to the Hadassah Hospital, Jerusalem, Israel, from October 2000 to December 2005. Patients were divided into 3 groups according to mechanism of injury: terror-related blast injury (n = 21), gunshot wounds (GSW) (n = 73) and blunt trauma (n = 87). Results: Median injury severity score in the blast group was significantly higher compared with GSW and blunt groups (34, 18, and 29, respectively, P < 0.0001). Injury to multiple body regions (≥3) occurred in 85.7% of blast group, 28.8% of GSW group, and 59.7% of blunt group (P < 0.001). The pattern of intra-abdominal injury was different between the groups. Bowel injury was found in 71.4% of blast victims, 64.4% of GSW, and 25.3% of blunt group (P < 0.001). Parenchymal injury was found in one third of patients in blast and GSW groups versus 60.9% of patients in blunt group (P = 0.001). Penetrating shrapnel was the cause of bowel injury in all but 1 patient in the blast group (94.4%). Conclusions: Terrorist attacks generate more severe injuries to more body regions than other types of trauma. Abdominal injury inflicted by terrorist bombings causes a unique pattern of wounds, mainly injury to hollow organs. Shrapnel is the leading cause of abdominal injury following terrorist bombings.

Gastrointestinal stromal tumor (GIST) is a rare neoplasm of the alimentary tract. Previous reports described an incidence of 1 per 100,000. Laparoscopic sleeve gastrectomy (LSG) provides pathological specimens of the majority of the stomach. We examined the pathology from LSG and the incidence and location of GIST. The aim of this study was to study the incidence of asymptomatic GISTs found during LSG at our institution. A search was conducted in a prospectively maintained bariatric registry. Data collected included the following: gender, age, body mass index (BMI), and concomitant hypertension or diabetes mellitus. Histopathology reports were reviewed for incidental GIST. We compared the patients with incidental GIST to the rest of the cohort. Pathology reports of 827 patients that underwent LSG between 2007 and 2014 were reviewed. Five patients had GIST in the resected stomach, an incidence of 0.6 %. The group of patients with GIST had lower BMI and older age compared to the remaining 822 patients. All tumors were located close to the lesser curvature. The incidence of GIST found in this cohort is significantly higher than previously reported. This may be due to an association between these tumors and obesity or because asymptomatic GISTs are underdiagnosed in the general population. These tumors are particularly common in older patients and special attention must be given when performing LSG on this subpopulation. The stomach should be inspected thoroughly before resection. A tumor on the lesser curvature may necessitate changing the surgical plan or aborting the procedure.

Single Incision Laparoscopic Surgery (SILS) is gaining popularity as a modality in surgery which reduces the number and size of skin incisions. General surgeons and urologists were the first to implement this technique, however, recently gynecologists have also started performing SILS procedures. We present the case of a 70 year old female who underwent a combined SILS procedure which included cholecystectomy, bilateral oophorectomy and omentectomy. The procedure lasted 100 minutes and the patient was discharged home the day after the operation. No operative or post-operative complications were noted. In this case report we present the technical details and demonstrate the collaboration between different disciplines which enables performing this complex and demanding procedure.

The incidence of geriatric trauma is rising with an increased life expectancy and a more active lifestyle among the elderly. The aim of this study was to describe the different patterns of injury with increased age in severely injured elderly patients and to identify predictors of in-hospital mortality.

Posttraumatic stress disorder (PTSD) is a psychiatric disorder that results from exposure to a traumatic event and consists of intrusive and unwanted recollections; avoidance followed by emotional withdrawal; and heightened physiologic arousal. Hospitalized victims of suicide bombing attacks (SBAs) are unique because of the circumstances and severity of their injuries, which could affect the occurrence and delay the recognition of PTSD. Our objectives were to evaluate the prevalence and severity of PTSD among hospitalized SBA victims and to assess variables of physical injury as risk factors for the development of PTSD.Forty-six hospitalized SBA victims were evaluated for PTSD using the PTSD symptom scale self-report questionnaire by phone. Demographic and medical data regarding the severity and type of injury and medical treatment were collected from medical files. Injury Severity Score was used to assess severity of physical injury.Twenty-four of 46 (52.2%) hospitalized SBA victims developed PTSD. Presence of blast lung injury was significantly higher in the PTSD group compared with the non-PTSD group (37.5% versus 9.1%, respectively; p0.04). There was no significant difference in Injury Severity Score between PTSD and non-PTSD groups. Blast lung injury and intracranial injury were found to be positive predictors of PTSD (odds ratio, 125 and 25, respectively). No correlation was found between the length of stay, length of intensive care unit stay, or severity of physical injuries and the severity of PTSD.Hospitalized victims of SBA are considerably vulnerable to develop PTSD. Victims should be monitored closely and treated in conjunction with their physical treatment. Blast lung injury and intracranial injury are predictors of PTSD.

We report a case of iatrogenic resection of both the superior mesenteric artery (SMA) and celiac artery during left nephrectomy and adrenalectomy. A 47-year-old woman was diagnosed with a large adrenal tumor and underwent a laparoscopic left adrenalectomy that was converted to open adrenalectomy and nephrectomy as a result of a bulky tumor. Both the SMA and celiac artery were inadvertently cut at their origin because of adherence of the tumor to the aorta. Both arteries were revascularized by anastomosing the distal splenic artery to the aorta after performing splenectomy to revascularize the celiac circulation and using an autologous saphenous vein graft to revascularize the SMA. The patient had no postoperative complications. To our knowledge, this is the first description of use of the splenic artery for celiac revascularization.

Mechanical trauma caused by PCI is a primary reason for restenosis and subsequent target lesion revascularization (TLR). To minimize this trauma, we developed a computerized angioplasty pressure sensor and inflator device (CAPSID) for gradual inflation. The objective of this prospective randomized study was to examine whether use of CAPSID reduces early and late cardiac events in patients undergoing PCI.Patients undergoing PCI were eligible and randomized to CAPSID or standard balloon inflation (plain old balloon angioplasty). In the CAPSID group, a slow, gradual balloon inflation was performed by a personal computer. Stenting was used in both groups only for suboptimal results. Patients with total occlusions and vein grafts were excluded. Clinical follow-up for major adverse cardiac events (MACE) was performed at 6 and 12 months, with repeat coronary angiography performed for clinical symptoms or positive stress testing.A total of 234 patients completed the study. At 1-year follow-up, the CAPSID group had a significantly lower rate of MACE (21% vs. 37%, P.005). In patients who underwent angiography, there was a significantly lower rate of restenosis in the CAPSID group (20.2% vs. 35.5%). The reduction in TLR was even more pronounced in the subgroup undergoing stenting (8% vs. 24%; P.001).We conclude that gradual computerized balloon inflation is more effective than standard manual balloon inflation in reducing adverse coronary events. The combination of CAPSID and subsequent stent deployment was especially effective in reducing TLR.

We present the case of an 18-year-old female transferred to our center from an outside hospital due to persistent gastrointestinal bleeding. Two weeks prior to her transfer she underwent duodenal omentopexy for a perforated duodenal peptic ulcer. The patient underwent a computed tomography angiogram which identified the source of bleeding as a giant gastro-duodenal artery (GDA) pseudoaneurysm. The patient was taken to interventional radiology where successful microcoil embolization was performed. We present this rare case of a giant GDA pseudoaneurysm together with imaging and a review of the medical literature regarding prevalence, etiology and treatment options for visceral arterial aneurysms.

BackgroundDue to high prevalence of type 2 diabetes mellitus (T2DM) and increasing popularity of bariatric and metabolic operations, Surgeons are faced with patients with relatively more severe T2DM disease. High level of glycated hemoglobin (HbA1c) is widely considered as a marker for uncontrolled T2DM. The aim of this study was to explore the correlation between high level of pre-operative HbA1c, peri-operative morbidity and post operative outcome after laparoscopic sleeve gastrectomy.MethodsWe conducted a retrospective study based on our medical center metabolic and bariatric registry. The inclusion criteria for selecting patients to the study group was HbA1c of 9 gram/dL and higher. A comparison control study was designed to include T2DM patients similar in all characteristics except for HbA1c of 7.5 gram/dl and less.ResultsWe included 20 patients who underwent laparoscopic sleeve gastrectomy. Each group of patients included half of the patients. The mean pre operative HbA1c in the studied and the control group were 10.4 gram/dL and 7.1 gram/dL respectively (p
