Evolution of practice gaps in gastrointestinal and endoscopic surgery: 2012 report from the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Continuing Education Committee.

BACKGROUND: In an effort to fulfill its charge to develop and maintain a comprehensive educational program to serve the members of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), the SAGES Continuing Education Committee (CEC) reports a summary of findings related to its evaluation of the 2012 SAGES annual meeting. METHODS: All attendees to the 2012 annual meeting had the opportunity to complete an immediate postmeeting questionnaire as part of their continuing medical education (CME) certification in which they identified up to two learning themes, answered questions related to potential practice change items that are based on those learning themes, and complete a needs assessment related to important learning topics for future meetings. In addition, participants in the postgraduate and hands-on courses were asked to complete questions about case volume and comfort levels related to procedures/topics in those courses. All respondents to this initial survey were sent a 3-month follow-up questionnaire in which they were asked how successfully they had implemented the intended practice changes and what, if any, barriers they encountered. Postgraduate and hands-on course participants completed case volume and comfort level questions. Descriptive statistical analysis of this deidentified data was undertaken. RESULTS: Response rates were 42% and 56% for CME-eligible attendees/respondents for the immediate postmeeting and 3-month follow-up questionnaires, respectively. Top learning themes for respondents were Bariatric, Hernia, Foregut, and Colorectal. Improving minimally invasive surgical (MIS) technique and managing complications related to MIS procedures were top intended practice changes. Partial implementation was common with top barriers including cost restrictions, lack of institutional support, and lack of time. CONCLUSIONS: The 2012 annual meeting analysis provides insight into educational needs among respondents and will help with planning content for future meetings.

Endoscopic identification of the jejunum facilitates minimally invasive jejunostomy tube insertion in selected cases.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG), direct percutaneous endoscopic jejunostomy, and laparoscopic feeding tube insertion are established techniques for placing a feeding tube. However, these techniques may be difficult or contraindicated after previous gastric or upper abdominal surgery. METHODS: A total of 10 patients underwent minimally invasive jejunostomy tube insertion via endoscopic identification of the jejunum. The indications for the procedure were dysphagia, poor nutritional status, prolonged intensive care unit (ICU) admission, and gastroparesis. Eight of the patients had undergone previous upper abdominal surgeries and were rejected for either PEG or direct percutaneous jejunostomy. With the patients under general anesthesia, esophagogastroduodenoscopy was performed. The jejunum was identified and intubated. A small abdominal incision (1 in.) was made. The proximal jejunum was identified easily by the light and digital palpation of the endoscope. The jejunum was delivered in the wound, and the jejunostomy tube was inserted using Witzel's technique. The wound was closed. RESULTS: All the patients tolerated the procedure well. The mean time for the procedure was 29 +/- 13 min. There was no mortality related to the procedure and no complications. Jejunal feeding started on the first postoperative day. CONCLUSION: The use of intraoperative endoscopy facilitated identification of the jejunum. Easy, safe, and quick, the procedure saved the patient a formal laparotomy and extensive manipulation.

The lateral paramedian: revisiting a forgotten incision.

Incisional hernia is a potential complication of all abdominal incisions and still remains a significant problem financially and medically. Presently, there is a lack of general consensus among surgeons in regard to the optimal treatment. The midline incision is the most common used abdominal incision and it carries a high incidence of incisional hernia (up to 15%). The paramedian incision was known to lead to a small incidence of incisional hernias. This discussion is meant to bring the paramedian incision back to the picture as a hope to decrease the incidence of incisional hernia.

Resting-state brain connectivity after surgical and behavioral weight loss.

OBJECTIVE: Changes in food-cue neural reactivity associated with behavioral and surgical weight loss interventions have been reported. Resting functional connectivity represents tonic neural activity that may contribute to weight loss success. This study explores whether intervention type is associated with differences in functional connectivity after weight loss. METHODS: Fifteen participants with obesity were recruited prior to adjustable gastric banding surgery. Thirteen demographically matched participants with obesity were selected from a separate behavioral diet intervention. Resting-state functional magnetic resonance imaging was collected 3 months after surgery/behavioral intervention. ANOVA was used to examine post-weight loss differences between the two groups in connectivity to seed regions previously identified as showing differential cue-reactivity after weight loss. RESULTS: Following weight loss, behavioral dieters exhibited increased connectivity between left precuneus/superior parietal lobule (SPL) and bilateral insula pre- to postmeal and bariatric patients exhibited decreased connectivity between these regions pre- to postmeal (P(corrected) <0.05). CONCLUSIONS: Behavioral dieters showed increased connectivity pre- to postmeal between a region associated with processing of self-referent information (precuneus/SPL) and a region associated with interoception (insula) whereas bariatric patients showed decreased connectivity between these regions. This may reflect increased attention to hunger signals following surgical procedures and increased attention to satiety signals following behavioral diet interventions.

Teaching the teacher: An ethical model for international surgical missions.

Concerns linger about how to provide equitable global health care and how to address the great unmet health care needs in many countries. The burden of outreach mostly falls on universities. Universities and educational institutions by design are capable of defining the necessary directions for change. The challenge for universities participating in global health care and education is creating and sustaining robust health systems tailored to each community by evaluating the existing system and taking note of stakeholders, opinion leaders, and the availability of sustained resources in the milieu of the rapidly changing global health care structures.4 The model described here is rooted in educational theory and based on the belief that sharing surgical knowledge is the most effective way to improve access to necessary care for underserved patient populations. Positive changes can be made by developing relationships among health care personnel and new approaches to educational problems. This positive outcome was largely due to the development of new attitudes by professionals and their approach to education and collaboration. Development of a systemic approach to global health care problems is a daunting task. The solution is neither simple nor easy, and the active participation of the assisted party is highly encouraged. *

Pre-surgical cortical activation to food pictures is associated with weight loss following bariatric surgery.

BACKGROUND: Recent research suggests that preintervention functional magnetic resonance imaging (fMRI) data may predict weight loss outcomes among patients who participate in a behavioral weight loss plan. No study has examined whether presurgical brain activation can predict outcomes following bariatric surgery. METHOD: The aim of the present study was to determine if brain activations during a presurgical fMRI food-motivation paradigm are associated with weight loss 3 and 6 months following laparoscopic adjustable gastric banding (LAGB). Nineteen participants viewed food and nonfood pictures from a well-established food motivation paradigm during an fMRI scanning session before LAGB surgery. Weight was assessed presurgery and 3 and 6 months postsurgery; data for all participants was available at each time point. fMRI data were analyzed using the BrainVoyager QX statistical package. Whole brain voxelwise correlations of presurgery (food-nonfood) brain activation and weight, corrected for multiple comparisons, were performed to analyze the relationship between presurgical brain activation and subsequent weight loss. The settings were a medical university brain imaging center and 2 surgical weight loss centers in a major metropolitan area. RESULTS: Increased activity in frontal regions associated with cognitive control (medial, middle, superior frontal gyrus) and posterior cingulate cortex was associated with weight loss following LAGB. CONCLUSION: We found that neural activity in previously established regions associated with cognitive and behavioral self-regulation predicts weight loss following bariatric surgery. These preliminary findings highlight the role of neural circuitry in the success and maintenance of weight loss and suggest a possible future use of fMRI in screening LAGB surgery candidates.
