Abstract
Purpose. The primary aim of the study was to review the existing literature about patient-reported outcome measures (PROMs) in colorectal cancer and IBD. The secondary aim was to present a road map to develop a core outcome set via opinion gathering using social media. Method. This study is the first step of a three-step project aimed at constructing simple, applicable PROMs in colorectal surgery. This article was written in a collaborative manner with authors invited both through Twitter via the #OpenSourceResearch hashtag. The 5 most used PROMs were presented and discussed as slides/images on Twitter. Inputs from a wide spectrum of participants including researchers, surgeons, physicians, nurses, patients, and patients' organizations were collected and analyzed. The final draft was emailed to all contributors and 6 patients' representatives for proofreading and approval. Results. Five PROM sets were identified and discussed: EORTC QLQ-CR29, IBDQ short health questionnaire, EORTC QLQ-C30, ED-Q5-5L, and Short Form-36. There were 315 tweets posted by 50 tweeters with 1458 retweets. Awareness about PROMs was generally limited. The general psycho-physical well-being score (GPP) was suggested and discussed, and then a survey was conducted in which more than 2/3 of voters agreed that GPP covers the most important aspects in PROMs. Conclusion. Despite the limitations of this exploratory study, it offered a new method to conduct clinical research with opportunity to engage patients. The general psycho-physical well-being score suggested as simple, applicable PROMs to be eventually combined procedure-specific, disease-specific, or symptom-specific PROMs if needed.

Abstract
Bleeding from the lower gastrointestinal tract represents a significant source of morbidity and mortality. The colon represents the vast majority of the location of bleeding with only a much smaller incidence occurring in the small intestine. The major causes of lower gastrointestinal bleeding (LGIB) are from diverticulosis, vascular malformations, and cancer. We discuss the incidence and causes of LGIB.

Abstract
AbstractBackgroundThere is widespread concern that treatment with biologic agents may be associated with suboptimal postoperative outcome after surgery for inflammatory bowel diseases (IBD).AimWe aimed to search and analyze the literature regarding the potential association of biologic treatment on adverse postoperative outcome in patients with IBD. We used the subject as a case in point for surgical research. The aim was not to conduct a new systematic review.MethodThis is an updated narrative review written in a collaborative method by authors invited through Twitter via the following hashtags (#OpenSourceResearch and #SoMe4Surgery). The manuscript was presented as slides on Twitter to allow discussion of each section of the paper sequentially. A Google document was created, which was shared across social media, and comments and edits were verified by the primary author to ensure accuracy and consistency.ResultsForty-one collaborators responded to the invitation, and a total of 106 studies were identified that investigated the potential association of preoperative biological treatment on postoperative outcome in patients with IBD. Most of these studies were retrospective observational cohorts: 3 were prospective, 4 experimental, and 3 population-based studies. These studies were previously analyzed in 10 systematic/narrative reviews and 14 meta-analyses. Type of biologic agents, dose, drug concentration, antidrug antibodies, interval between last dose, and types of surgery varied widely among the studies. Adjustment for confounders and bias control ranged from good to very poor. Only 10 studies reported postoperative outcome according to Clavien–Dindo classification.ConclusionAlthough a large number of studies investigated the potential effect of biological treatment on postoperative outcomes, many reported divergent results. There is a need for randomized controlled trials. Future studies should focus on the avoiding the weakness of prior studies we identified. Seeking collaborators and sharing information via Twitter was integral to widening the contributors/authors and peer review for this article and was an effective method of collaboration.

Abstract
The processes that control the progression of ductal carcinoma in situ (DCIS) to invasive breast cancer remain poorly understood. Epidermal growth factor receptor 2 (ErbB2) over expression is common in DCIS, as is disruption of the retinoblastoma tumor suppressor (RB) pathway. Here we examined the cooperative impact of ErbB2 and RB deregulation on facets of disease progression. Our studies demonstrate that RB deficiency altered the expression of key molecules needed for proper cellular organization and epithelial cell-cell adhesion as part of a program related to the epithelial to mesenchymal transition (EMT). An increase in the invasive potential of ErbB2 over expressing cells was observed upon RB depletion. Furthermore, stable knockdown of RB resulted in invasive lesions in orthotopic xenograft assays, compared to DCIS-like lesions developing from RB-proficient cells. Conversely, the invasive phenotype observed in ErbB2-positive cancer models was inhibited through CDK4/6 inhibition in an RB-dependent manner. Lastly, in a cohort of DCIS cases, we show that while elevated levels of ErbB2 are associated with increased risk of a subsequent DCIS recurrence, it is not associated with progression to invasive disease. In contrast, RB loss in ErbB2 positive DCIS cases was associated with increased risk for invasive breast cancer. Taken together, these data demonstrate a key role for the RB-pathway in invasion associated with breast tumor progression, and shed light on the key molecular events that promote the progression of DCIS to invasive disease.

Abstract
Despite multiple efforts aimed at early detection through screening, colon cancer remains the third leading cause of cancer-related deaths in the United States, with an estimated 51000 deaths during 2013 alone. The goal remains to identify and remove benign neoplastic polyps prior to becoming invasive cancers. Polypoid lesions of the colon vary widely from hyperplastic, hamartomatous and inflammatory to neoplastic adenomatous growths. Although these lesions are all benign, they are common, with up to one-quarter of patients over 60 years old will develop pre-malignant adenomatous polyps. Colonoscopy is the most effective screening tool to detect polyps and colon cancer, although several studies have demonstrated missed polyp rates from 6%-29%, largely due to variations in polyp size. This number can be as high as 40%, even with advanced (> 1 cm) adenomas. Other factors including sub-optimal bowel preparation, experience of the endoscopist, and patient anatomical variations all affect the detection rate. Additional challenges in decision-making exist when dealing with more advanced, and typically larger, polyps that have traditionally required formal resection. In this brief review, we will explore the recent advances in polyp detection and therapeutic options.

Abstract
INTRODUCTION The surgical management of ulcerative colitis (UC) often involves complex operations. We investigated the outcome of patients who underwent surgery for UC by analyzing a nationwide database. METHODS We queried the American College of Surgeons National Surgical Quality Improvement Program database (ACS-NSQIP, 2005-2008) for all UC patients who underwent colectomy. To analyze by operation, groupings included: partial colectomy (PC; n = 265), total abdominal colectomy (TAC; n = 232), total proctocolectomy with ileostomy (TPC-I; n = 134), and total proctocolectomy with ileal pouch-anal anastomosis (IPAA; n = 446) to analyze 30-day outcomes. RESULTS From 1,077 patients (mean age, 44 years; 45 % female; 7 % emergent), a laparoscopic approach was used in 29.2 %, with rates increasing 8.5 % each year (18.5 % in 2005 to 41.3 % in 2008, P < 0.001). Complications occurred in 29 %, and laparoscopy was associated with a lower complication rate (21 vs. 32 % open, P < 0.001). On multivariate regression, postoperative complications increased when patients were not functionally independent [odds ratio (OR) = 3.2], had preoperative sepsis (OR = 2.0), or prior percutaneous coronary intervention (OR = 2.8). A laparoscopic approach was associated with a lower complication rate (OR = 0.63). When stratified by specific complications, laparoscopy was associated with lower complications, including superficial surgical site infections (11.4 vs. 6.7 %, P = 0.0011), pneumonia (2.9 vs. 0.6 %, P = 0.023), prolonged mechanical ventilation (3.9 vs. 1.3 %, P = 0.023), need for transfusions postoperatively (1.6 vs. 0 %, P = 0.016), and severe sepsis (2.9 vs. 1.0 %, P = 0.039). Laparoscopy was also was associated with a lower complication rate in TACs (41.7 vs. 18.8 %, P < 0.0001) and IPAA (29.9 vs. 18.2 %, P = 0.005) and had an overall lower mortality rate (0.2 vs. 1.7 %, P = 0.046). CONCLUSIONS Results from a large nationwide database demonstrate that a laparoscopic approach was utilized in an increasing number of UC patients undergoing colectomy and was associated with lower morbidity and mortality, even in more complex procedures, such as TAC and IPAA.

Abstract
PURPOSE Single-incision laparoscopic colectomy represents a potential advance in minimally invasive surgical approaches to colorectal disease. Although widely promoted, outcome data are virtually absent. A group of highly experienced laparoscopic attending colorectal surgeons convened to standardize technique and prospectively record operative details and outcomes. METHODS Single-incision laparoscopic colectomy was performed by 10 experienced attending colorectal surgeons with minimal or no prior single-incision laparoscopic colectomy experience. Surgeon rating of ergonomics and 15 components of operation conduct was compared with conventional multiple-port laparoscopic colectomy. Patient demographics, operative details, and outcome data were prospectively collected. RESULTS Thirty-nine single-incision laparoscopic colectomies were performed (25 right colectomies, 5 ileocolic resections, 8 sigmoidectomies, and 1 low anterior resection). Underlying pathology included polyps (12), cancer (15), Crohn's disease (5), and diverticulitis (7). Patients were highly selected with a mean body mass index of 25.6 (range, 16-40). Two conversions to open resection occurred, 1 because of fistula and 1 because of adhesions, in patients with a mean body mass index of 34. An additional port was required in 3 patients. Mean incision length was 4.2 cm (range, 2.5-8) and operative time was 120 minutes (range, 68-210). Complications included 1 wound infection and 2 anastomotic bleeds requiring transfusion. Average length of stay was 4.4 days (range, 2-8). Mean lymph node harvest was 19 (range, 12-39). Exposure, instrument conflict, ergonomics, ease of instrumentation, and camera operation were rated significantly more difficult with single-incision laparoscopic colectomy than with multiple-port laparoscopic colectomy. CONCLUSIONS Preliminary data demonstrate that single-incision laparoscopic colectomy can be performed safely in selected patients by experienced surgeons. The benefits of single-incision compared with multiple-port laparoscopic colectomy are not immediately evident. Despite the advanced skills of the faculty, a learning curve of undetermined length still exists in which specific components of single-incision laparoscopic colectomy are more difficult than multiple-port laparoscopic colectomy, and areas of focus remain that require advances to make single-incision laparoscopic colectomy equivalent to multiple-port laparoscopic colectomy. The multi-institutional registry will enable further analysis of single-incision laparoscopic colectomy.

Abstract
The diminishing enthusiasm towards performing splenectomy (SPL) either as an integral part of surgical cancer management (SCM), or for staging/management (ST) of lymphoma, warranted our assessment of the extent of this trend in a minority population. We retrospectively analysed all SPL submitted to Surgical Pathology for histological processing over a 24-year period (1/1/70-12/31/93) at the Howard University Hospital, a predominantly African-American institution. Of the 446 SPL performed during the period, sixty-nine (15.5%) were performed as part of SCM/ST. Seventy-five per cent (52/69) were for solid intra-abdominal cancers (SIC) and 25% (17/69) for lymphoma. As a group, the patients were older, 71% over 40 years old) and showed a male predominance (61% males). Sixty-two per cent (43/69) of the SPL were performed in the decade 1970-1979. In the following decade 1980-1989, the frequency with which SPL was performed, had dropped to 33% (23/69). Four years into the current decade, 1990-1993, only 5% (3/69) of the SPL were performed for SCM/ST. These findings suggest that in African-Americans, the performance of SPL in ST/SCM has been declining over the years, which is in agreement with the current growing trends in cancer treatment i.e. to avoid unnecessary operations, limit morbidity, preserve important organs, maintain immunocompetence of the patient and to utilize advanced imaging techniques in ST/SCM.
