RESUMO
BACKGROUND: Achalasia is a rare disorder of the esophagus characterized by motor dysfunction in the esophagus and relaxation failure of the lower esophageal sphincter (LES). Currently, surgical myotomy procedures are considered the standard of care. Robotic Heller's myotomy (RHM) with fundoplication has been gaining popularity due to documented advantages in the precision of myotomy as well as avoiding the potential reflux following per-oral endoscopic myotomy (POEM). To the best of our knowledge, RHM has thus far has been performed exclusively by the da Vinci surgical system. The new Hugo RAS™ system offers a unique modular design and an open console which offers better maneuverability and docking options. In this study, we present the first worldwide series of patients undergoing RHM using the new Hugo RAS™ platform. Our objective is to propose optimal operating configuration and setup to fully harness the advantages of the unique modular design of this system. METHODS: Ten consecutive achalasia patients underwent Robotic Heller's myotomy (RHM) with the Hugo RAS™ system. We prospectively collected patient data, including demographics, comorbidities, ASA class, Eckardt scores, pre-operative manometric data, and EndoFlip parameters. Additionally, we recorded the docking and total operative times. RESULTS: Between December 2022 and August 2023, 10 patients underwent RHM with the Hugo™ RAS system. Patients had a median age of 42.5 years, 60% were female, and mean BMI was 23.2. Fifty percent had achalasia type 2 and 50% type 1. The median pre-operative integrated relaxation pressure (IRP) was 24.9. Median docking time was 10 min and overall operative time was 129.5 min. All patients, except one with acute coronary syndrome, had an uneventful peri-operative course and were discharged on post-operative day 2. CONCLUSION: The Hugo™ RAS system is well designed for robotic Heller myotomy. The operative and clinical results are similar to the currently used robotic system; however, the modular design of the system has some differences. These translate to better docking angles and maneuverability as well as console surgeon's ergonomics. Further experience is needed to explore the advantages of the system's modular design and function.

Background: Low anterior resection syndrome (LARS) is a post-proctectomy consequence characterized by variable and unpredictable bowel function, including clustering, urgency, and incontinence, which significantly impacts the quality of life. Currently, there is no established gold-standard therapy for LARS. Primary Study Objective: This study aimed to evaluate the effectiveness of the Paula method of exercise as part of an integrative treatment approach for patients with LARS. Design: This preliminary study utilized a single-arm pretest-posttest design. Setting: The study was conducted at a tertiary care medical center. Participants: Five patients diagnosed with LARS completed the study. Intervention: Participants underwent twelve weeks of individualized Paula method exercise sessions. Two questionnaires were employed to assess the severity of LARS and quality of life. Primary Outcome Measures: (1) Low Anterior Resection Syndrome (LARS) Score; (2) Memorial Sloan Kettering Cancer Bowel Function Instrument (MSK-BFI); (3) Global Quality-of-Life (QOLS) Score . Results: All participants completing the 12-week Paula exercise regimen reported no difficulty in engaging with the exercises. Statistically significant improvements were observed in both the LARS score and MSK-BFI (P = .039 and P = .043, respectively, Wilcoxon Rank Sum test). While there were improvements in the global quality-of-life score and functional scales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, these improvements did not reach statistical significance. Conclusions: This preliminary study suggests that patients with LARS can successfully complete a 12-week exercise program using the Paula method, resulting in improved LARS scores. However, further investigation through larger, multicenter, randomized controlled trials is necessary to establish the efficacy of these exercises as a treatment for LARS.

PURPOSE: Up to 20% of patients suffering from symptomatic hemorrhoids will require surgery. Excisional hemorrhoidectomy (EH) and stapled hemorrhoidopexy (SH) are both standard and safe procedures. While SH has a short-term advantage of faster recovery and lower postoperative pain, its long-term efficacy is debatable. This study aims to compare the outcomes of EH, SH, and a combined procedure of both. METHODS: A retrospective study compared the outcomes of patients treated surgically for hemorrhoids over a 5-year period. Eligible patients were asked by phone to complete a questionnaire evaluating recurrent symptoms, fecal incontinence, satisfaction, and self-assessed improvement in quality of life (QOL). RESULTS: This study included 362 patients, of whom 215 underwent SH, 99 underwent EH, and 48 underwent a combined procedure. No statistically significant differences were found between groups regarding complications, symptoms recurrence, or fecal incontinence. Combined procedure patients had significantly higher self-assessed improvement in QOL (P=0.04). CONCLUSION: In patients with symptomatic hemorrhoids, a tailored approach to symptomatic hemorrhoids is associated with high satisfaction rates and self-assessed improvement in QOL.

INTRODUCTION: Robotic-assisted surgery has been a part of surgical procedures for more than two decades. Recently new robotic platforms with a different design entered the market. The modular design with independent arms enables increased flexibility of arm docking to increase the range of motion and instrument maneuverability. We herein present the first case series of robotic inguinal hernia repair using the Hugo RAS system (Medtronic, Minneapolis, MN, USA). MATERIAL AND METHODS: Thirteen inguinal hernia repairs were performed on ten patients. A description of the Hugo RAS system as well as the new concept of modular design is presented along with the description of the operation setup. RESULTS: Mean docking time was 9.5 min and mean console time was 50.3 min and 74.7 min for unilateral and bilateral inguinal hernia repair, respectively. No intraoperative or postoperative complications occurred. There was one conversion to laparoscopic surgery due to a technical issue with the robot. Conclusions: The modular design of independent arms seems to enhance maneuverability of the instruments and contribute to fewer arm collisions. Further clinical data and experience with this new surgical system are necessary to understand if this new design has advantages over the standard robotic platforms.

BACKGROUND: The appropriate strategies to minimize skeletal deterioration following bariatric surgeries are inconclusive. This randomized controlled trial evaluated the effect of preoperative vitamin supplementation on bone mineral density (BMD) and biochemical parameters in females post-sleeve gastrectomy (SG). METHODS: Participants were randomized to a 2-month preoperative treatment with a multivitamin and vitamin D 4000 IU/d (intervention arm) or 1200 IU/d (control arm). Preoperative and 12-month postoperative follow-up evaluations included anthropometrics, biochemical parameters, and dual energy X-ray absorptiometry (DEXA). RESULTS: Sixty-two females (median age 29.7 years and median BMI 43.4 kg/m2) were recruited, 87% completed the 12-month follow-up. For the intervention and control arms, significant and similar reductions at 12-months post-surgery were observed in BMD of the hip (-6.8 ± 3.7% vs. -6.0 ± 3.6%; P = 0.646) and of the femoral neck (-7.1 ± 5.8% vs. -7.2 ± 5.5%; P = 0.973). For the intervention compared to the control arm, the 25 hydroxyvitamin D (25(OH)D) increment was greater after 2 months treatment, and vitamin D deficiency rates were lower at 3 and 6-months follow-up (P < 0.016). However, at 12-months postoperative, 25(OH)D values and vitamin D deficiency were comparable between the arms (P > 0.339). Predictors for BMD decline in the total hip were the percentage of excess weight-loss, age>50 years, and lower initial BMI (P ≤ 0.003). CONCLUSIONS: SG was associated with a significant decline in BMD of the hip and femoral neck in young and middle-aged women, and was unaffected by preoperative vitamin D supplementation. Females who are peri-menopausal or with greater postoperative weight-loss should be particularly followed for BMD decline.

BACKGROUND: Emergency laparotomy (EL) is an increasingly common procedure in the elderly. Factors associated with mortality in the subpopulation of frail patients have not been thoroughly investigated. Sarcopenia has been investigated as a surrogate for frailty and poor prognosis. Our primary aim was to evaluate the association between easily measured sarcopenia parameters and 30-day postoperative mortality in elderly patients undergoing EL. Length of stay (LOS) and admission to an intensive care unit were secondary end points. METHODS: We conducted a retrospective cohort study, over a 5-year period, of patients aged 65 y and older who underwent EL at a tertiary university hospital. Sarcopenia was evaluated on admission computed tomography scan by two methods, first by psoas muscle attenuation and second by the product of perpendicular cross-sectional diameters (PCSDs). The lowest quartile of PCSDs and attenuation were defined as sarcopenic and compared with the rest of the cohort. Attenuation was stratified for the use of contrast enhancement. Multivariant logistic regression was performed to determine independent risk factors. RESULTS: During the study period, 403 patients, older than 65 y, underwent EL. Of these, 283 fit the inclusion criteria and 65 (23%) patients died within 30 d of surgery. On bivariate analysis, psoas muscle attenuation, but not PCSDs, was found to be associated with 30-day mortality (OR = 2.43, 95% CI = 1.34-4.38, P = 0.003) and longer LOS (35.7 d versus 22.2 d, Δd 13.5, 95% CI = 6.4-20.7, P < 0.001). In a multivariate analysis, psoas muscle attenuation, but not PCSDs, was an independent risk factor for 30-day postoperative mortality (OR = 2.35, 95% CI = 1.16-4.76, P = 0.017) and longer LOS (Δd = 14.4, 95% CI = 7.7-21.0, P < 0.001). Neither of the sarcopenia parameters was associated with increased admission to an intensive care unit. DISCUSSION: Psoas muscle attenuation is an independent risk factor for 30-day postoperative mortality and LOS after EL in the elderly population. This measurement can inform clinicians about the operative risk and hospital resource utilization.

BACKGROUND: Colorectal cancer is a condition which is associated with substantial morbidity and mortality. The aim of this study was to assess urinary dysfunction and its effect on quality of life in women who underwent total mesorectal excision compared to women treated by partial mesorectal excision for treatment of rectal cancer. METHODS: We performed a retrospective cohort study at a tertiary university hospital between January 2014 and December 2019. A comparison was performed between women who underwent total mesorectal excision as opposed to partial mesorectal excision for treatment of rectal cancer. Pre-operative, intra-operative and post-operative data were compared between groups. Data regarding radiation therapy was recorded and compared as well. Urinary dysfunction and its impact on quality of life were assessed using UDI-6 and USIQ questionnaires. Further univariate and multivariate analyses were performed in the attempt of assessing risk factors for urinary dysfunction. RESULTS: A total of 107 women were included in the study, 73 women underwent partial mesorectal excision as opposed to 34 women who were treated by total mesorectal excision. Twenty-five women in the TME group underwent radiation therapy prior to surgery as opposed to none in the PME group (p < 0.001). Urinary dysfunction following surgery as assessed using the UDI-6 questionnaire did not differ between groups. Similar findings were recorded with regard to the impact of urinary dysfunction on quality of life as assessed using the USIQ questionnaire. Following multivariate analysis longer hospital stay was associated with increased risk of some degree of urinary dysfunction. CONCLUSIONS: Women undergoing total mesorectal excision have comparable results to partial mesorectal excision with regard to urinary dysfunction.

INTRODUCTION: Esophageal achalasia is a rare condition, characterised by progressive dysphagia due to innervation of the esophageal muscles and non-relaxation of the lower esophageal sphincter. The standard of care of surgical treatment is laparoscopic Heller myotomy. POEM-Peroral endoscopic myotomy is a new approach offering incision-less and selective myotomy. AIMS: This study aims to describe our experience and outcomes using this new surgical technique. METHODS: We performed a retrospective study using prospectively maintained data of all achalasia patients treated by POEM in our department. Data collected included patient demographics, gender, age, BMI, data related to the disease course in addition to data related to the surgery itself as well as both short and long term post-operative follow-up. RESULTS: Over the course of five years we performed 86 POEM operations, demonstrating a decrease in the Eckardt score from a mean of 8.87 to a mean of 0.7 in the immediate postoperative. Mean operative time was 86 minutes, with mean hospitalization time of 4 days. Intraoperative complications included 2 mucosal injuries while post-operative complications included 4 incomplete mucosal closures, 5 recurrent dysphagia and 5 patients with reflux requiring medical therapy. CONCLUSIONS: In the last decade, POEM procedure is being performed worldwide and has been performed in our department for the past five years. Our results show a success rate of 94.2% with minor complications. In our institution, as in many institutions globally, POEM is the preferred method for treating achalasia.

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.

BACKGROUND: Our aim was to evaluate the advantages and limitations of delayed laparoscopic cholecystectomy (LC) in a tertiary center. MATERIALS AND METHODS: A retrospective analysis of all patients admitted to our institution with acute calculous cholecystitis (ACC) between January 2003 and December of 2012 was performed. Data collected included patient demographics and comorbidities, presenting symptoms, laboratory findings, imaging results, length of stay (LOS), time to surgery, and surgical complications. RESULTS: A total of 1078 patients were admitted with ACC. There were 593 females (55%), and the mean age was 57 ± 0.6 years. Mean LOS at initial admission, re-admission until surgery, and following surgery was 7.9 ± 0.2, 1.5 ± 0.1, and 3.4 ± 0.2 days, respectively. Percutaneous cholecystostomy (PC) tube was inserted in 24% of the patients. Only 640 (59%) patients eventually underwent LC. Mean time to surgery was 97 ± 9.8 days, and 16.4% of patients were readmitted in this time period resulting in a mean total LOS of 10.6 ± 0.2 days. Conversion rate to open surgery was 5.8% and bile duct injury occurred in 1.1%. Postoperative complications occurred in 9.8% of the patients, and 30-day mortality was 0.6%. Patients with more severe inflammation according to Tokyo Criteria grade were more likely to undergo PC, were more likely to be readmitted while waiting for LC, and also had more postoperative complications. CONCLUSIONS: Delayed LC is associated with significant loss of follow-up, long LOS, and higher than expected use of PC. Conversion rates are lower than in the literature while rates of bile duct injury and mortality are comparable. We believe these data as well as the available literature are sufficient to change our hospital policy regarding the surgical treatment of ACC from delayed to early same admission surgery in appropriate cases.

BACKGROUND: Trans-anal total mesorectal excision (Ta-TME) is a novel approach for the resection of rectal cancer. Low anterior resection syndrome (LARS) is a frequent functional disorder that might follow restorative proctectomy. Data regarding bowel function after Ta-TME are scarce. The aim of this study was to evaluate the incidence and risk factors for the development of LARS following Ta-TME. METHODS: A prospectively maintained database of all patients who underwent Ta-TME for rectal cancer at our institution was reviewed. All patients who were operated on from January 2018 to December 2021 were evaluated. The LARS score questionnaire was used via telephone interviews. Incidence, severity and risk factors for LARS were evaluated. RESULTS: Eighty-five patients underwent Ta-TME for rectal cancer between January 2018 and December 2021. Thirty-five patients were excluded due to ostomy status, death, local disease recurrence, ileal pouch or lack of compliance. Fifty patients were included in the analysis. LARS was diagnosed in 76% of patients. Anastomosis distance from dentate line was identified as a risk factor for LARS via multivariate analysis (p = 0.042). Neo-adjuvant therapy, hand sewn anastomosis and anastomotic leak did not increase the risk of LARS. CONCLUSION: LARS is a frequent condition following ta-TME, as it is used for other approaches to low anterior resection. Anastomosis distance from dentate line is an independent risk factor for LARS. In this study neo-adjuvant therapy, hand sewn anastomosis and anastomotic leak did not increase the risk of LARS. Further studies with longer follow-up times are required to better understand the functional outcomes following Ta-TME.
RESUMO
Introduction: Hiatal hernia (HH) is a common disorder of the upper gastrointestinal (UGI) tract that general surgeons encounter. Giant paraesophageal is a subtype of HH in which more than 30% of the stomach is located in the chest. It can cause symptoms such as dysphagia, UGI bleeding, gastroesophageal reflux disease, and vomiting. As the life expectancy of the general population increases, the incidence of giant HH increases and can cause morbidity, including recurrent admissions and prolonged length of hospitalization. In this article, we describe a cohort of nonagenarian patients with HH who were admitted to our institution and were treated either surgically or medically. Methods: We retrospectively reviewed our prospectively maintained database of all nonagenarians who were admitted to our center between 2018 and 2022 with the diagnosis of HH. We compared the demographic data, clinical data, and outcomes between patients undergoing operative and nonoperative management. Results: Twenty patients of age over 90 years were hospitalized with HH-related symptoms. Six underwent surgery, whereas 14 received medical management. Surgical patients had fewer overall hospitalization days, shorter length of stay, and less blood product requirements. Notably two cases of in-hospital mortality occurred in the nonoperative group, whereas none occurred in the operative group. All surgical procedures were performed laparoscopically, with two minor perioperative complications. Conclusion: In selected nonagenarian patients, laparoscopic HH repair is safe and should be considered favorably. It can reduce hospitalization time and can mitigate morbidity.

BACKGROUND: Gastroesophageal reflux disease (GERD) is a common condition, resulting from the loss of the anti-reflux barrier. Laparoscopic fundoplication is the surgical procedure of choice for treatment of GERD; however, there remains a debate on the exact mechanism through which it prevents reflux. OBJECTIVES: Our aim was to understand the relationship between reflux, fundoplication, and the angle of His on an experimental model. METHODS: The study was conducted on four groups of fresh explanted swine stomachs: control group, myotomy, myotomy with Nissen fundoplication, and myotomy with Toupet fundoplication. The stomachs were placed in a specially designated container on an inclinable platform which would increase the hydrostatic pressure on the esophago-gastric junction. Measurements of the angle of His using fluoroscopy and the esophago-gastric orifice area using endoscopy were performed, and the occurrence of reflux was documented. RESULTS: Each group of the study contained nine swine stomachs. In the control and myotomy groups, the angle became wider as the incline level increased the pressure and was significantly different between the groups (p < .001). Both groups demonstrated an increase in the orifice area as the incline level increased the pressure. There was a significant correlation between the angle of His and the area of the esophago-gastric orifice (p < .001). In the control group, the reflux began at the 0°. In the myotomy group, it began at the + 15° incline (less pressure). Reflux rarely occurred in the Nissen and Toupet groups, with the breaking point being mostly defined as "beyond - 30°". A significant difference was noted in the occurrence of reflux between fundoplication and the non-fundoplication groups (p < 0.001), while there was no significant difference between the Toupet and Nissen groups (p = 0.134). Analysis showed a significant independent correlation between both the angle of His and the orifice area with the presence of reflux (p = .002 and p = .024 respectively). CONCLUSIONS: In this study, we developed an experimental model to enable careful evaluation of the elements of the anti-reflux mechanism, of which, the angle of His has a measurable element. We demonstrated that as the angle of His becomes wider the esophago-gastric orifice area becomes larger. Additionally, a wider angle of His and a larger esophago-gastric orifice area were correlated independently with more reflux. This suggests that the fundoplication creates an acute angle of His which is correlated with a smaller area of the esophago-gastric orifice and eventually with a lower incidence of reflux.

BACKGROUND: Peroral endoscopic myotomy (POEM) is rapidly becoming the procedure of choice for treating esophageal achalasia. In most centers, contrast-enhanced swallow studies (CESS) are routinely performed postoperatively to confirm mucosal integrity. The aim of this study was to determine the necessity of performing these studies routinely after POEM. METHODS: A retrospective review of a prospectively maintained database of patients who underwent POEM between December 2012 and November 2020 was performed. All patients underwent a CESS on the first postoperative day. Medical records including vital signs, complete blood count, and POD-1 CESS were evaluated. RESULTS: One hundred thirty-four consecutive patients were included in the study. Sixty-nine (51.49%) CESS showed abnormal findings; while most findings did not change the postoperative course, five (7.2%) demonstrated tunnel leaks, which did alter the overall management. Screening patients for fever, tachycardia, or leukocytosis on POD-1 had a 100% sensitivity and a 62% specificity for finding a clinically significant complication on CESS. CONCLUSIONS: The study findings suggest that performing routine contrast-enhanced swallow studies on all patients is not necessary following POEM, as leaks can be screened for by clinical or laboratory abnormalities. Herein, we propose an algorithm based on objective measurable findings for the selection of patients who should undergo CESS.

Backgrounds/Aims: Traumatic pancreatic injury (TPI) is rare as an isolated injury. There is a trend to perform conservative treatment even in patients with complete duct dissection and successful treatment. This study reviewed our 20 years of experience in the management of TPI and assessed patient outcomes according to age group and treatment strategy. Methods: A retrospective analysis of patients diagnosed and treated with TPI at a level-I trauma center from 2000-2019. Patients were divided into two groups: adults and pediatrics. Conservative treatment cases were subjected to subgroup analysis. Level of evidence: IV. Results: Of a total of 77 patients, the mean age was 24.89 ± 15.88 years. Fifty-six (72.7%) patients had blunt trauma with motor vehicle accident. Blunt trauma was the predominant mechanism in 42 (54.5%) patients. Overall, 38 (49.4%) cases had grade I or II injury, 24 (31.2%) had grade III injury, and 15 (19.5%) had grade IV injury. A total of 30 cases had non-operative management (NOM). Successful NOM was observed in 16 (20.8%) cases, including eight (32.0%) pediatric cases and eight (15.4%) adult cases. Higher American association for the surgery of trauma (AAST) grade of injury was associated with NOM failure (16.7% for grade I/II, 100% for grade III, and 66.7% for grade IV injury; p = 0.001). An independent factor for NOM failure was female sex (69.2% in females vs. 29.4% in males; p = 0.03). Conclusions: High AAST grade TPI is associated with a high rate of NOM failure in both pediatric and adults.
RESUMO
PURPOSE: Oral anticoagulants (AC) and antiplatelet (AP) agents are increasingly prescribed to prevent and treat acute and chronic thrombotic conditions. The direct oral anticoagulants (DOAC), a newer class of AC, raise concerns in the trauma setting. Our study aims to compare the mortality rates and other outcomes among adult trauma patients based on pre-admission AC/AP status. METHODS: We conducted a retrospective cohort study of a prospectively collected database of trauma patients previously on DOAC, warfarin, aspirin or clopidogrel. A matched control group of trauma patients not receiving AC/AP was used for comparison. Our primary endpoint was in-hospital mortality according to antithrombotic medication class. Secondary endpoints included length of stay (LOS), intensive care unit (ICU) admission, need for blood transfusion, and discharge to a dependent setting. Univariate and multivariate analyses were conducted. RESULTS: There were 996 exposed patients and 234 controls, with no major clinically significant difference among study groups in terms of gender, injury site, injury severity, mechanism, and comorbidities. The mortality rates were 2.14% (control, 5/234), 2.88% (DOAC, 3/104), 3.34% (aspirin, 17/509), 7.63% (warfarin, 18/236), 9% (clopidogrel, 8/89), and 13.79% (aspirin + clopidogrel, 8/58) (p < 0.001). In multivariate analyses, there was no difference regarding mortality between DOAC and reference groups. Blood transfusion was more likely in patients receiving warfarin or AP than those prescribed DOAC. CONCLUSION: There was no evidence of increased mortality or blood transfusion requirement among trauma patients on DOAC, including head trauma patients. Further studies on head trauma and specific subgroups of DOAC are recommended.

BACKGROUND: As the field of minimally invasive surgery continues to develop, surgeons are confronted with the challenge of performing conventional laparoscopic surgeries through fewer incisions while maintaining the same degree of safety and surgical efficiency. Most of these methods involve elimination of the ports previously designated for retraction. As a result, minimally invasive surgeons have been forced to develop minimally invasive and ingenious methods for providing adequate retraction for these procedures. Herein we present our experience using endoloops and internal retractors to provide retraction during Single Incision Minimally Invasive Surgery (SIMIS) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) cholecystectomy. We also present a review of the alternative retraction methods currently being employed for these surgeries. METHODS: SIMIS was performed on 20 patients and NOTES was performed on 5 patients at our institution. Endoloops or internal retractors were used to provide retraction for all SIMIS procedures. Internal retractors provided retraction for all NOTES procedures. RESULTS: Successful cholecystectomy was accomplished in all cases. One SIMIS surgery required conversion to standard laparoscopy due to complex anatomy. There were no intraoperative complications. Although adequate retraction was accomplished in all cases, the internal retractors were found to provide superior and more versatile retraction compared to that of endoloops. CONCLUSION: Adequate retraction greatly simplifies SIMIS and NOTES surgery. Endograb internal retractors were easy to use and were found to provide optimal retraction and exposure during these procedures without complications.

Goblet cell carcinoma, a tumor that is assumed to originate from crypt base stem cells, is a distinct type of tumor, that occurs typically in the appendix, however, extra-appendiceal locations were also described in few cases. We herein present a unique case of a 48-year-old male with a diagnosis of primary gastric Goblet cell carcinoma that was initially discovered at the time of an endoscopy performed to evaluate an unremitting abdominal pain that was accompanied by remarkable weight loss; four polypoid fragments of the gastric mucosa were sent for histopathologic examination which showed a moderately differentiated goblet cell carcinoma in addition to classical neuroendocrine tumor. Later, laparoscopic D2 total gastrectomy with appendectomy were performed and confirmed the previously mentioned findings along with a normal histopathology of the appendix.

BACKGROUND: Nutritional deficiencies are a well-recognized long-term complication following bariatric surgery. The presence of preoperative deficiencies has been shown to be predictive of postoperative deficiencies. OBJECTIVE: The aim of the study was to investigate the prevalence of micronutrient deficiency in a large sample of patients with severe obesity preoperatively, and to determine whether such deficiencies may be related to patient's sex, body mass index, or ethnic subgroup. DESIGN: A cross-sectional study of data collected at the time of the preoperative evaluation. PARTICIPANTS/SETTING: Data were collected during the preoperative evaluation of 872 bariatric surgery candidates in a university hospital in Israel between 2011 and 2018. The patients were 72.9% women, with a mean age of 37.9±12.1 years and mean body mass index of 42.4±4.7 MAIN OUTCOME MEASURES: Nutritional deficiencies according to blood assays. Data on anthropometrics, comorbidities, and demographic characteristics was also collected. STATISTICAL ANALYSES: Baseline differences between patient subgroups were analyzed using independent-samples t test, analysis of variance, or χ2 test. RESULTS: Deficiencies of vitamin D, iron, folate, vitamin B-12, elevated parathyroid hormone and low transferrin saturation were present in 75.2%, 42.6%, 28.5%, 8.5%, 35.5%, and 70% of patients, respectively. Nutritional deficiencies were significantly more common among women compared with men for iron (45.9% vs 33.5%; P=0.002), low transferrin saturation (77.7% vs 44.6%; P<0.001), vitamin D (77.5% vs 69.2%; P=0.019) and elevated parathyroid hormone level (39.5% vs 22.9%; P=0.002). Iron, transferrin saturation, and vitamin D deficiencies were more prevalent in Arab patients compared with Jewish patients: 59.6% vs 36%; P<0.001, 80.2% vs 62.8%; P=0.003, and 85.1% vs 71.6%; P<0.001, respectively. Vitamin D and iron deficiency were more common among higher body mass index subgroups (P=0.004 and P=0.040, respectively). CONCLUSIONS: The results indicate a high prevalence of nutritional deficiencies, mainly of iron and vitamin D in bariatric surgery candidates. Patients at higher risk for nutritional deficiencies include those with higher body mass index, women, and Arabs.

Up to 80% of patients who undergo bariatric surgery are women of childbearing age. Coupled with improved fertility in women with obesity after bariatric surgery, pregnancy postbariatric surgery has become increasingly more common. Although numerous studies have evaluated associations of bariatric surgery with pregnancy outcomes, the effect of maternal nutritional status on maternal and perinatal outcomes is not well established. We used Medline and Embase databases and a manual search of references for articles published until June 2018 to conduct a systematic review on nutritional status after bariatric surgery and its association with maternal and perinatal outcomes. Of the 306 initially identified articles, 27 met the study inclusion criteria, comprising 2056 women with pregnancies after bariatric surgery. Deficiencies were reported in maternal concentrations of vitamins A, B1, B6, B12, C, D, K, iron, calcium, selenium, and phosphorous. The only adverse events documented for these deficiencies encountered during pregnancy were anemia (vitamin B12, iron), night blindness (vitamin A), and urinary tract infections (vitamin A, D). This systematic review suggests that various micronutrient deficiencies are common among pregnant postbariatric surgery patients. Nevertheless, despite the concern that these deficiencies could adversely affect pregnancy outcomes (e.g., lower neonatal birth weight), evidence of such is lacking. Further prospective studies are warranted to confirm our findings and better delineate the optimal supplementation regimen during pregnancy after bariatric surgery.
