Weight stigma in healthcare settings: the experience of Arab and Jewish bariatric surgery candidates in Israel.

BACKGROUND: Weight-related stigma and discrimination are prevalent in our society with adverse biopsychosocial outcomes to people with obesity and morbid obesity. Studies suggest that weight bias in healthcare settings are quite prevalent, but there have been, as far as we know, lack of studies examining prevalence and correlates of weight bias experiences among bariatric surgery candidates in Israel. We aim to understand the nature and prevalence of weight stigma among bariatric surgery candidates. To identify differences between Jewish and Arab candidates. To examine the impact of weight stigma experiences on weight bias internalization (WBI). METHODS: A cross-sectional study was performed among 117 adult bariatric surgery candidates from three hospitals in northern Israel (47.8% Jews, 82.4% females, average BMI 42.4 ± 5.2 Kg/meter2). Patients who agreed to participate completed a structured questionnaire on the same day that the bariatric surgery committee met. WBI was measured using a validated 10-item scale. Experiences of weight stigma were measured using items adapted from prior international studies. RESULTS: About two thirds of the participants had at least one experience of weight stigma (teased, treated unfairly, or discriminated against because of their weight). As many as 75% of participants reported that weight served as a barrier to getting appropriate health care and as many as half of participants felt in the last year that a doctor judged them because of their weight. No significant differences were found between Arabs and Jews in the prevalence of weight stigma experiences and WBI. However, a trend towards more stigma experiences among Jews was noted. WBI was predicted by female gender and experiences of weight stigma, both in general and within healthcare settings. CONCLUSIONS: Weight stigma towards bariatric surgery candidates in Israel is quite prevalent, and specifically in healthcare settings. It is important to adopt policy actions and intervention programs to improve awareness to this phenomenon among the general public and specifically among healthcare providers, as many healthcare providers may be unaware of the adverse effect of weight stigma and of ways in which they are contributing to the problem. Future studies may validate our findings using larger sample size and longitudinal design.

Automatic performance evaluation of the intracorporeal suture exercise.

PURPOSE: This work uses deep learning algorithms to provide automated feedback on the suture with intracorporeal knot exercise in the fundamentals of laparoscopic surgery simulator. Different metrics were designed to provide informative feedback to the user on how to complete the task more efficiently. The automation of the feedback will allow students to practice at any time without the supervision of experts. METHODS: Five residents and five senior surgeons participated in the study. Object detection, image classification, and semantic segmentation deep learning algorithms were used to collect statistics on the practitioner's performance. Three task-specific metrics were defined. The metrics refer to the way the practitioner holds the needle before the insertion to the Penrose drain, and the amount of movement of the Penrose drain during the needle's insertion. RESULTS: Good agreement between the human labeling and the different algorithms' performance and metric values was achieved. The difference between the scores of the senior surgeons and the surgical residents was statistically significant for one of the metrics. CONCLUSION: We developed a system that provides performance metrics of the intracorporeal suture exercise. These metrics can help surgical residents practice independently and receive informative feedback on how they entered the needle into the Penrose.

Laparoscopic management of iatrogenic colon perforation.

BACKGROUND: Iatrogenic colon perforation (ICP) due to colonoscopy is a severe complication and is associated with significant morbidity and mortality. The global estimated incidence of ICP is 0.03% and up to 3% for diagnostic and therapeutic colonoscopies, respectively. Treatment options include endoscopic repair, conservative therapy, and surgery. Treatment decision is based on the time and the setting of the diagnosis, the type, and location of the perforation, the presence of related pathologies, the clinical status and characteristic of the patient, and surgeon's skills. We present our experience in the treatment of ICPs. METHODS: A retrospective review was undertaken of all patients suffering from ICP at Bnai-Zion Medical Center between 1/1/2010 and 1/3/2021. Clinical presentation, therapeutic approach, and short-term outcomes were analyzed. RESULTS: There were 51 cases of ICPs. Fourteen (27%) were diagnosed by the gastroenterologist during the procedure, 2 of whom were treated with endoscopic clips. The rest of the patients (72.5%) were diagnosed in the ER after a CT scan. Forty-three patients (84%) went on to operative management: 5 (11%) operations started with laparotomy-all were conducted in the early study period (until 2013). All other operations (88%) started with a diagnostic laparoscopy, 4 of whom (10%) were converted to laparotomy. Out of the 38 laparoscopic cases 29 (80%) were treated with primary suturing. Seven patients went on to colon resection (5 of whom with primary anastomosis). Six patients required ICU admission-with 1/38 (2%) from the laparoscopic cases, and 5/9 (55%) from the laparotomy cases. A total of 49/51 (96%) patients recovered and were discharged after 5 ± 2 for conservative and laparoscopic cases, and 12 ± 9 for open cases. CONCLUSION: Laparoscopic treatment of ICP is safe and feasible in most cases. Our data supports a laparoscopic attempt at any such scenario.

Comparing a novel wide field of view laparoscope with conventional laparoscope while performing laparoscopic cholecystectomy.

BACKGROUND: The limited 70° field of view (FoV) used in standard laparoscopy necessitates maneuvering the laparoscope to view the ports, follow the surgical tools, and search for a target region. Complications related to events that take place outside the FoV are underreported. Recently, a novel laparoscopic system (SurroundScope, 270Surgical) was reported to dramatically expand the FoV from 70 to 270°. This study focuses on differences in performing laparoscopic cholecystectomy using the SurroundScope compared to the standard laparoscope. METHODS: Forty-four laparoscopic surgeries were performed and video recorded. A subanalysis of 21 Cholecystectomies was performed and compared to 21 Cholecystectomies, performed with the standard laparoscope during the study period by the same surgeon. RESULTS: No accidental or intraoperative adverse events occurred when using the SurroundScope. Subanalysis of 21 Cholecystectomies revealed shorter fog/smoke cleaning times using the SurroundScope compared to the standard scope (1.45 ± 5.08 sec vs. 54.95 ± 137.77 sec, p = 0.0454). Furthermore, operations performed with the SurroundScope had a shorter trocar placement duration (85.0 ± 40.9 sec vs. 111.3 ± 70.5 sec; p = 0.077), shorter time to achieve critical view of safety (9.5 ± 4.14 min vs. 15.8 ± 11.87 min; p = 0.015), and shorter procedure duration (31.9 ± 10.4 min vs. 42.9 ± 22 min; p = 0.025). In post-operative evaluations, the surgeon noted that tools could be continuously followed and ports were visible without camera manipulation. Also, the surgeon agreed that the procedure could be better planned due to the wide FoV and that surgical workflow was improved. Furthermore, the surgeon agreed that the procedure was safer using the SurroundScope. CONCLUSIONS: Initial results demonstrate the advantages of the SurroundScope over standard laparoscopy. By expanding the FoV, visualization is improved, the procedure is more efficient, significantly shorter and most important, patient safety, per surgeons' testimonials is improved. Further investigation to quantify these benefits in a larger group of patients and among various surgical procedures should be considered.

Effects of wide-angle laparoscopy on surgical workflow in laparoscopic cholecystectomies.

INTRODUCTION: Laparoscopy is now the gold standard approach to many surgical procedures thanks to its many advantages. Minimizing distractions is essential to a safe and successful surgery and an undisrupted surgical workflow. The SurroundScope, a wide angle (270°) laparoscopic camera system has the potential to decrease surgical distractions and increase workflow. METHODS: Forty-two laparoscopic cholecystectomies were performed by a single surgeon, 21 with the SurroundScope and 21 with standard angle laparoscope. Video recordings of surgeries were reviewed for calculating the number of entries of surgical tools into the field of view, relative time of tools and ports viewed in surgical field and number of times camera was removed due to fog or smoke. RESULTS: The usage of the SurroundScope resulted in a significantly lower number of entries to the field of view compared to the standard scope (58.50 versus 102; P < 0.0001). Usage of SurroundScope resulted in a significantly higher appearance ratio of tools, with a value of 1.87 compared to 1.63 for standard scope (P-value < 0.0001), and the appearance ratio of ports was also significantly higher, measuring 1.84 compared to 0.27 for the standard scope (P-value < 0.0001). In addition, the SurroundScope had to be removed and reinserted due to smoke or fog in only 2 cases (9.5%), compared to 12 cases (57.1%) in the standard scope group (P-value < 0.01). CONCLUSIONS: The SurroundScope camera system improves surgical workflow in laparoscopic cholecystectomy. This conceivably increase the safety of the operation due to the utilization of the wide-angle view and "chip on the tip" technology.

Automatic assessment of performance in the FLS trainer using computer vision.

BACKGROUND: Fundamentals of Laparoscopic Surgery (FLS) box trainer is a well-accepted method for training and evaluating laparoscopic skills. It mandates an observer that will measure and evaluate the trainee's performance. Measuring performance in the Peg Transfer task includes time and penalty for dropping pegs. This study aimed to assess whether computer vision (CV) may be used to automatically measure performance in the FLS box trainer. METHODS: Four groups of metrics were defined and measured automatically using CV. Validity was assessed by dividing participants to 3 groups of experience levels. Twenty-seven participants were recorded performing the Peg Transfer task 2-4 times, amounting to 72 videos. Frames were sampled from the videos and labeled to create an image dataset. Using these images, we trained a deep neural network (YOLOv4) to detect the different objects in the video. We developed an evaluation system that tracks the transfer of the triangles and produces a feedback report with the metrics being the main criteria. The metric groups were Time, Grasper Movement Speed, Path Efficiency, and Grasper Coordination. The performance was compared based on their last video (3 participants were excluded due to technical issues). RESULTS: The ANOVA tests show that for all metrics except one, the variance in performance can be explained by the experience level of participants. Senior surgeons and residents significantly outperform students and interns on almost every metric. Senior surgeons usually outperform residents, but the gap is not always significant. CONCLUSION: The statistical analysis shows that the metrics can differentiate between the experts and novices performing the task in several aspects. Thus, they may provide a more detailed performance analysis than is currently used. Moreover, these metrics calculation is automatic and relies solely on the video camera of the FLS trainer. As a result, they allow independent training and assessment.

The introduction of wide-angle 270° laparoscopy through a novel laparoscopic camera system.

BACKGROUND: Laparoscopy has enjoyed improvements over the last three decades primarily in achieving high definition, but the 70° field of view (FOV) remains unchanged. Complications related to events that take place out of the FOV continue to be reported. Additional problems leading to poor visualization are fogging and smoke accumulation. A novel laparoscopic system (SurroundScope, 270Surgical) was developed and dramatically expands the FOV from the 70° to 270° by adding side cameras at the distal tip of the laparoscope, while LED illumination eliminates fogging and improves smoke effects. This study describes the initial clinical experience with SurroundScope and its potential advantages over traditional laparoscopy. METHODS: SurroundScope was studied at Bnai Zion Medical Center in Israel and the Minnesota Institute for Minimally Invasive Surgery in America. 27 laparoscopic surgeries were performed, and at the end of each procedure, evaluations were completed by all surgeons and camera holders. RESULTS: All 27 cases were completed successfully without adverse events. No injuries occurred as a result of surgical tool manipulation outside of the central frame while 133 potentially adverse events were identified on side frames. There was no fogging across the 27 cases. The impact of smoke was negligible in all cases, as laparoscope removal or venting was never necessary. Surgeon respondents indicated that tools could be followed from the port to the site of surgery without camera manipulation. Most surgeons strongly agreed that the potential to identify bleeding was improved. Camera holders strongly agreed that the ergonomics were improved and that they moved the camera less than with a standard laparoscope. CONCLUSIONS: Initial results demonstrate numerous advantages for SurroundScope as compared to traditional laparoscopy. The important benefits of expanded FOV, complete lack of fogging, and negligible smoke may improve patient safety, reduce adverse events and the duration of surgery. Further investigation to quantify these benefits is recommended.

Sleeve Gastrectomy Failure-Revision to Laparoscopic One-Anastomosis Gastric Bypass or Roux-n-Y Gastric Bypass: a Multicenter Study.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric procedure performed worldwide. However, many patients undergo secondary surgery due to either weight-related and complication-related reasons or both. Conversional options vary with one-anastomosis gastric bypass (OAGB) and Roux-n-Y gastric bypass (RYGB) being the most common. The aim of the study was to assess the safety and efficacy of converting failed LSG to either OAGB or RYGB, and compare weight-related results and post-conversion complications. METHODS: Retrospective review of hospital records of patients who underwent conversion from LSG to either RYGB or OAGB due to insufficient weight loss or weight regain in 7 bariatric centers between 2013 and 2019. Data retrieved included demographics, anthropometrics, comorbidities, indication for conversion, conversion type, complications, and weight loss. RESULTS: During the study period, 396 patients were included in the study. Eighty-four (21%) patients were lost to follow-up. RYGB and OAGB were performed in 119 and 144 patients, respectively. Mean age and body mass index (BMI) at revision were 44.2 years (range 19-72) and 40.6 ± 5.9 kg/m2 (range 35-71), respectively. Of these, 191 (73%) were female. Percent total body weight loss (%TWL) was 16% ± 1% for the RYGB group vs. 23% ± 12% for the OAGB group (p = 0.0007) at a median follow-up of 29 months (range 7-78 months) following conversion. Gastroesophageal reflux disease (GERD) was significantly higher 1 year following conversion to OAGB vs. RYGB occurring in 25 (17.4%) and 9 (7.6%) patients, respectively (p = 0.018). CONCLUSIONS: Conversion of LSG to OAGB, compared to RYGB, results in increased weight loss but a higher rate of GERD and potential nutritional deficiencies.

Unilateral Adrenalectomy for Primary Bilateral Macronodular Adrenal Hyperplasia: Analysis of 71 Cases.

OBJECTIVE: Primary bilateral macronodular adrenal hyperplasia (PBMAH) is characterized by benign bilateral enlarged adrenal masses, causing Cushing's syndrome (CS). The aim of the current article is to define the role of unilateral adrenalectomy (UA) in treating patients with CS related to PBMAH. METHODS: A PubMed database search was conducted to identify articles reporting UA to treat PBMAH. We also report cases of PBMAH from our medical center treated by UA. RESULTS: A total number of 71 cases of PBMAH (62 cases reported in the literature and 9 cases from our center) are presented. Most patients were women (73.2%) and most UA involved the left side (64.3%). In most cases, the resected gland was the larger one. Following UA, 94.4% of cases had remission of hypercortisolism. Recurrence rate of CS was 19.4% and hypoadrenalism occurred in 29.6%. After UA, when the size of the remained adrenal gland was equal or greater than 3.5 cm, CS persisted in 21.4% of cases, and recurrence occurred in 27.3% of cases (after 20±9.2 months). However, when the size of the remained gland was less than 3.5 cm, CS resolved in all cases and recurrence occurred in 21.2% of cases after a long period (65.6±52.1 months). High levels of urinary free cortisol (UFC) were not correlated with post-surgical CS recurrence or persistence. CONCLUSIONS: UA leads to beneficial outcomes in patients with CS related to PBMAH, also in cases with pre-surgical elevated UFC or contralateral large gland.

Complementary and alternative medicine interventions for perioperative symptoms: A comparative effectiveness study.

INTRODUCTION: Perioperative symptoms such as pain, nausea and anxiety are often inadequately treated. We conducted a pragmatic trial to evaluate the impact of Complementary and Alternative Medicine (CAM) treatments on these symptoms, within the framework of a general surgery department that integrates CAM. METHODS: Patients ≥ 18 years referred to CAM treatments by surgical medical staff were allocated to standard of care with CAM treatment (CAM group) or without, according to patient preference and practitioner availability. CAM treatments included Acupuncture, Reflexology, or Guided Imagery. The primary outcome variable was the change from baseline in symptom severity, measured by Visual Analogue Scale (VAS). Patients and practitioners were asked to report any adverse effects associated with CAM treatments. RESULTS: A total of 1127 patients were enrolled, 916 undergoing 1214 CAM treatments and 211 controls. Socio-demographic characteristics were similar in both groups. Patients in the CAM group had more severe baseline symptoms. Symptom reduction was greater in the CAM group compared with controls, with a mean reduction in pain of -2.17 ±â€¯2.4 vs -0.29 ±â€¯2 (P < 0.0001); nausea -1.2 ±â€¯2.42 vs -0.3 ±â€¯1.94 (P < 0.0001); and anxiety -2.23 ±â€¯2.76 vs -0.03 ±â€¯2.54 (P < 0.0001). Acupuncture was more effective for nausea control. No significant adverse events were reported with any of the CAM therapies. CONCLUSION: CAM treatments provide additional relief to Standard Of Care (SOC) for perioperative symptoms. Larger randomized control trial studies with longer follow-ups are needed to confirm these benefits. The study is registered with clinical trials.gov at (NCT01733771).

Postoperative analgesia by adding acupuncture to conventional therapy, a non-randomized controlled trial.

Background Postoperative pain is common in patients hospitalized in surgical departments, yet it is currently not sufficiently controlled by analgesics. Acupuncture, a complementary medical practice, has been evaluated for its benefits in postoperative pain with heterogeneous results. We tested the feasibility of a controlled study comparing the postoperative analgesic effect of acupuncture together with standard-of-care to standard-of-care only. Methods In this pilot non-randomized controlled study conducted at a tertiary medical center in Israel, patients received either acupuncture with standard-of-care pain treatment (acupuncture group) or standard-of-care treatment only (control group) following surgery. Visual Analogue Scale (VAS) ratings for pain level at rest and in motion were evaluated both at recruitment and two hours after treatment. Acupuncture-related side effects were reported as well. Results We recruited 425 patients; 336 were assigned to the acupuncture group and 89 to the control group. The acupuncture group exhibited a decrease of at least 40% in average level of pain both at rest (1.8±2.4, p<0.0001) and in motion (2.1±2.8, p<0.0001) following acupuncture, whereas the control group exhibited no significant decrease (p=0.92 at rest, p=0.98 in motion). Acupuncture's analgesic effect was even more prominent in reducing moderate to severe pain at baseline (VAS ≥4), with a decrease of 49% and 45% of pain level at rest and in motion respectively (p<0.001), compared with no significant amelioration in the control group (p=0.20 at rest, p=0.12 in motion). No major side effects were reported. Conclusion Integrating acupuncture with standard care may improve pain control in the postoperative setting.

Analgesic Effects of Reflexology in Patients Undergoing Surgical Procedures: A Randomized Controlled Trial.

OBJECTIVE: Inadequate treatment of pain in patients undergoing surgery is associated with unsatisfactory perioperative outcomes. The aim of this study was to examine the role of reflexology in addition to standard analgesic treatment in postoperative pain management. DESIGN: This was a prospective, unblinded pragmatic controlled trial. SETTING/LOCATION: Study participants included patients who were admitted to the general surgery department. INTERVENTIONS: Patients in the intervention group received reflexology while standard analgesic care was administered similarly in both groups. OUTCOME MEASURES: Pain intensity at rest and in motion was evaluated using visual analog scale (VAS [0-10]) at baseline, and 60-90 min after treatment. RESULTS: Pain reduction was clinically and statistically significant in the reflexology group, both for pain at rest (from mean VAS of 4.4 to 3.1, N = 77, p < 0.0001) and for pain in motion (from 6.2 to 4.2, N = 77, p < 0.0001). In the control group, pain at rest was not reduced at follow-up (from 4.7 to 4.6, N = 87, p = 0.92), nor was pain in motion (from 5.8 to 5.7, N = 87, p = 0.65). Comparison of mean difference for pain showed significant improvement in the reflexology group compared to the standard of care group (p < 0.0001). The most significant pain reduction in the reflexology group was observed among patients who had moderate-severe baseline pain (VAS >4). CONCLUSION: Adding reflexology to standard analgesic care is effective in reducing postoperative pain at rest and in motion, especially for patients experiencing moderate to severe pain.

Development and validation of a tool to evaluate Inpatient Beliefs, Expectations and Attitudes toward Reflexology (IBEAR-16).

BACKGROUND: The integration of manual therapies, including reflexology, into conventional care settings is growing extensively. Patients' beliefs, attitudes and expectations toward these therapies interact with their outcomes, but currently there are no validated tools to evaluate these factors. We aimed to design and to validate such a tool specifically targeted into reflexology. METHODS: Following input of a multidisciplinary team of experts, the self-administered Inpatient Beliefs, Expectations and Attitudes toward Reflexology (IBEAR) questionnaire was constructed, containing 25 items, 8 referring to demographics and 17 specifically addressing reflexology. Cronbach's alpha was computed to evaluate the questionnaire's internal reliability, and factor analysis was used for further validation (232 patients). Pearson coefficient and Kappa tests were used to test and retest (within 48 hours) the questionnaire on a group of 199 patients, to assure clarity and reliability. RESULTS: For the 232 questionnaires collected, the computed Cronbach's alpha coefficient was 0.716 (acceptable reliability). Factor analysis pointed to two content areas separated into four items addressing attitudes and expectations and five items focusing on beliefs and attitudes. In the test-retest stage, 199 participants filled in the questionnaire for a second time. The Pearson coefficient for all questions ranged between 0.73 and 0.94 (good to excellent correlation) and Kappa scores ranged between 0.66 and 1.0 (moderate to high reliability). Consequently, one of the questions was removed from the IBEAR. CONCLUSIONS: The present study provides evidence that the proposed IBEAR questionnaire with 16 items is a valid and reliable tool for evaluation of inpatients' beliefs, expectations and attitudes toward reflexology.

Effectiveness of integrating individualized and generic complementary medicine treatments with standard care versus standard care alone for reducing preoperative anxiety.

STUDY OBJECTIVE: Preoperative anxiety is commonly reported by people undergoing surgery. A significant number of studies have found a correlation between preoperative anxiety and post-operative morbidity. Various methods of complementary and alternative medicine (CAM) were found to be effective in alleviating preoperative anxiety. This study examined the relative effectiveness of various individual and generic CAM methods combined with standard treatment (ST) in relieving preoperative anxiety, in comparison with ST alone. DESIGN: Randomized controlled trial. SETTING: Holding room area PATIENTS: Three hundred sixty patients. INTERVENTIONS: Patients were randomly divided into 6 equal-sized groups. Group 1 received the standard treatment (ST) for anxiety alleviation with anxiolytics. The five other groups received the following, together with ST (anxiolytics): Compact Disk Recording of Guided Imagery (CDRGI); acupuncture; individual guided imagery; reflexology; and individual guided imagery combined with reflexology, based on medical staff availability. MEASUREMENTS: Assessment of anxiety was taken upon entering the holding room area (surgery preparation room) ('pre-treatment assessment'), and following the treatment, shortly before transfer to the operating room ('post-treatment assessment'), based on the Visual Analogue Scale (VAS) questionnaire. Data processing included comparison of VAS averages in the 'pre' and 'post' stages among the various groups. MAIN RESULTS: Preoperatively, CAM treatments were associated with significant reduction of anxiety level (5.54-2.32, p<0.0001). In contrast, no significant change was noted in the standard treatment group (4.92-5.44, p=0.15). Individualized CAM treatments did not differ significantly in outcomes. However, CDRGI was less effective than individualized CAM (P<0.001), but better than ST (p=0.005). CONCLUSIONS: Individual CAM treatments integrated within ST reduce preoperative anxiety significantly, compared to standard treatment alone, and are more effective than generic CDRGI. In light of the scope of preoperative anxiety and its implications for public health, integration of CAM therapies with ST should be considered for reducing preoperative anxiety.

Totally laparoscopic versus laparoscopic-assisted left colectomy for cancer: a retrospective review.

BACKGROUND: Laparoscopic left colectomy (LLC) became the standard of care for treating distal transverse and descending colon cancer in many centers. Most centers use laparoscopic-assisted colectomy with extracorporeal anastomosis (LAC/EA). A totally laparoscopic colectomy with intracorporeal anastomosis (TLC/IA) has been proposed. The purpose of our study is to compare these two techniques. METHODS: A series of 52 patients undergoing LLC for left-sided colon cancer was retrospectively evaluated. Thirty-three patients underwent TLC/IA, and 19 underwent LAC/EA. The following data were collected: gender, age, body mass index, American Society of Anesthesiologists risk class, operation duration, conversion to laparotomy, intraoperative complications, postoperative complications, postoperative course (duration of stay, time to first flatus), number of excised lymph nodes, readmission, and reoperation rates. Data were prospectively recorded in a colorectal cancer database and retrospectively analyzed. RESULTS: The only demographic parameter that differed significantly between the groups was age (64.2 ± 12.4 years for the TLC/IA group, vs. 72.7 ± 2.1 years for LAC/EA, p = 0.0116). The mini-laparotomy incision was significantly shorter in the TLC/IA than in the LAC/EA group (5.8 ± 0.9 vs. 8.2 ± 0.9 cm, respectively, p < 0.00001). Hospital stay duration was shorter in the TLC/IA group (4.2 ± 1.2 vs. 6.3 ± 1.9, p = 0.0001). The average number of harvested lymph nodes did not differ significantly between the groups (12.9 ± 5.7 in TLC/IA vs. 11.2 ± 4.2 in LAC/EA, p = 0.2546). No significant differences between the groups were observed in any other perioperative or surgical outcome parameters. CONCLUSIONS: TLC/IA in LLC for the treatment of left colon cancer is technically feasible and can be performed with a low complication rate, favorable cosmetics, and possibly shorter hospital stay, without significantly lengthening operative duration or compromising oncologic radicality principles. Although further prospective randomized studies are needed to determine its role and limitations, we encourage using it as an alternative to LAC/EA in LLC.

Israeli Arabs develop diverticulitis at a younger age and are more likely to require surgery than Jews.

BACKGROUND: Only few studies have examined the impact of racial differences on the age of onset, course and outcomes of diverticulitis. AIM: To provide data about the epidemiology of diverticulitis in northern Israel, and to determine whether ethnicity is a predictor of age of onset, complications, and need for surgery. METHODS: Was conducted a retrospective review of the charts of all patients diagnosed with a first episode of diverticulitis in our hospital between 2005 and 2012. RESULTS: Were found 638 patients with a first episode of acute diverticulitis in the eight year interval. Israeli Arabs developed a first episode of diverticulitis at a younger age compared to Jews (51.2 vs 63.8 years, p<0.01). Arabs living in rural areas developed diverticulitis at a younger age than Arabs living in urban centers (49.4 vs 54.5 years, P=0.03). Jewish and Arabic men developed diverticulitis at younger age compared to their female counterparts (59.9 vs 66.09, p<0.01, and 47.31 vs 56.93, p<0.01, respectively). Arabs were more likely [odds ratio (OR)=1.81 ,95% confidence interval (CI)1.12-2.90, p=0.017] than Jews to require surgical treatment (urgent or elective) for diverticulitis. CONCLUSIONS: Israeli Arabs tend to develop diverticulitis at a younger age and are more likely to require surgical treatment for diverticulitis compared to Jews. Arabs living in rural areas develop diverticulitis at a younger age than Arabs living in urban centers. These findings highlight a need to address the root cause for ethnic differences in onset, course and outcome of acute diverticulitis.

RACIONAL: Somente poucos estudos examinaram o impacto das diferenças raciais na idade de início, curso e os resultados da diverticulite. OBJETIVO: Fornecer dados sobre a epidemiologia da diverticulite no norte de Israel, e determinar se a etnia é preditor de idade de início, complicações e necessidade de tratamento cirúrgico. MÉTODOS: Foi realizado estudo retrospectivo dos prontuários de todos os pacientes diagnosticados com um primeiro episódio de diverticulite em nosso hospital entre 2005 e 2012. RESULTADOS: Foram encontrados 638 pacientes com um primeiro episódio de diverticulite aguda no intervalo de oito anos. Os árabes israelenses desenvolveram o primeiro episódio de diverticulite em idade mais jovem em comparação com os judeus (51,2 vs 63,8 anos, p<0,01). Árabes que vivem em áreas rurais a diverticulite foi desenvolvida em idade mais jovem do que os árabes que vivem em centros urbanos (49,4 vs 54,5 anos, p=0,03). Homens judeus e árabes desenvolveram diverticulite em idade mais jovem em comparação com os seus homólogos do sexo feminino (59,9 vs 66,09, p<0,01, e 47,31 vs 56,93, p<0,01, respectivamente). Os árabes eram mais prováveis ​​do que os judeus de necessitar de tratamento cirúrgico (urgência ou eletiva) para a diverticulite [odds ratio (OR)=1,81, intervalo de confiança de 95% (CI) 1,12-2,90, p=0,017]. CONCLUSÕES: Os árabes israelenses tendem a desenvolver diverticulite em idade mais jovem e são mais propensos a necessitar de tratamento cirúrgico para a diverticulite em comparação com os judeus. Árabes que vivem em áreas rurais desenvolvem diverticulite em idade mais jovem do que os árabes que vivem em centros urbanos. Estes resultados destacam a necessidade de abordar a causa raiz para diferenças étnicas em início, o curso e o resultado da diverticulite aguda. .

Minimizing Hemorrhagic Complications in Laparoscopic Sleeve Gastrectomy--a Randomized Controlled Trial.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has gained worldwide popularity in recent years. Hemorrhagic complications (HC) are usually the result of stapler line bleeding and are probably underreported. The previous incidence of HC in our department including minor bleeding and late hematomas was 15.0 %. The objective of this study is to assess the impact of stapler line reinforcement (SLR) and intraoperative blood pressure control on HC after LSG. METHODS: Between February 2013 and March 2014, patients who were admitted to our department for LSG were randomly assigned to one of three arms: stapler line application of biologic glue--Evicel™ (E), over suture of the stapler line (S) or control (C). Surgical technique in all arms included blood pressure elevation to 140 mmHg before termination of the procedure. Data is presented as mean ± SD or median (IQR 25-75). RESULTS: One hundred sixty-five patients were randomized: 49 to E, 49 to S, and 67 to C. There were no demographic differences between arms. Operative time was significantly longer in S than in E and C arms (74 ± 21 vs. 64 ± 23 and 54 ± 19 min, respectively). ∆Hb was significantly lower in the S group. Packed cells were used in two from E and one from C arms. Late infected hematoma occurred in three (1.8 %) patients: one from E and two from C arms. Leak rate was 1.2 %: one from S and one from C arms. LOS was the same. No patients were re-operated due to bleeding. CONCLUSIONS: In this randomized trial, routine elevation of systolic blood pressure to 140 mmHg and over suture of the staple line in LSG minimized HC, with reasonable prolongation of the procedure.

Hypnosis-induced mental training improves performance on the Fundamentals of Laparoscopic Surgery (FLS) simulator.

BACKGROUND: Mental training (MT) is used extensively by musicians and athletes to improve their performance. Recently, it has been suggested as a training method for surgical trainees. We assessed the influence of MT, induced by hypnosis, on the performance of simulated tasks on a laparoscopic simulator, as compared to a non-specific relaxing intervention. METHODS: 11 surgeons completed a proficiency-based training program on the Fundamentals of Laparoscopic Surgery (FLS) simulator, until they reached performance plateau of the peg transfer task. Thereafter, they received a single music session, as a relaxing intervention, followed by repeating of the peg transfer task. Then they went through a hypnosis session guided by an experienced psychologist, with suggestions of smooth flow of pegs from one position on the board to another, and re-performed the task. RESULTS: Plateau performance was 51.1 ± 6.9 s. After the music session performance improved by 6.3% to 47.9 ± 5.4 s (p = 0.86). After the MT session performance further improved by 15.3% to 40.1 ± 5.8 s (p = 0.009), which was a 21.6% improvement from baseline (p < 0.001). Subject's satisfaction from their performance, without knowledge of the task scores, was 6.0 ± 2.9 on 0-10 VAS after the music and reached as high as 8.5 ± 1.7 after the hypnotic session (p = 0.01). CONCLUSIONS: Hypnosis-induced MT significantly improves performance on the FLS simulator, which cannot be attributed to its relaxing qualities alone. This study contributes evidence to the effectiveness of MT in surgical skills acquisition and suggests that hypnotic techniques should be used in mental preparation processes. There is a need to further study these effects on operating room performance.
