    Abstract Background: Ulcerative colitis (UC) is a chronic mucosal inflammatory bowel disease of the colon and rectum. After 10 years of having the disease, there is a significant risk of dysplasia or cancer in the affected colon and rectum, and because of the often aggressive biology of these tumors, frequent endoscopic surveillance is warranted. Over a third of patients with UC will ultimately require an operation, and although for specific cases alternative operations can be pursued, most patients prefer an ileal pouch-anal anastomosis (IPAA) with J-pouch construction.
    Case: A staged IPAA removes the affected colon and rectum treating UC and also restores intestinal continuity. However, the standard colectomy for UC includes low ligations of the main colonic vascular pedicle branches (ileocolic, right colic, middle colic and inferior mesenteric) that does not address a proper oncologic operation. A high ligation of the named vessels as well as a proper resection of the affected colon with its mesentery and lymph node package are needed to treat colon cancer. Analogous to a total mesorectal exicision for rectal cancer, a more radical procedure to remove the tumor and lymph node packet for colon cancer is described as a complete mesocolic exision (CME) in efforts to increase disease free survival.
    Discussion: We demonstrate a laparoscopic subtotal colectomy for UC, with an oncologic complete mesocolic excision for a left transverse colon carcinoma in the setting of chronic mucosal inflammation secondary to chronic UC as the first procedure in a 3-staged IPAA. In the video, it is also demonstrated how the lymph node dissection is extended towards the greater gastric curvature and comprising omentum and gastrocolic ligament. There were no postoperative complications in the 44-year old male patient.

    Abstract Total proctocolectomy and ileal pouch anal anastomosis (IPAA) is the gold standard surgical treatment for the majority (∼90%) of ulcerative colitis (UC) patients. In cases of carefully selected Crohn's colitis patients without small bowel or perianal involvement an "intentional IPAA" may be a viable option for disease resection and restoration of intestinal continuity. More commonly, Crohn's is incidentally found either in the resection specimen or, more commonly, when inflammatory complications subsequently arise after pouch construction for UC or indeterminate colitis. These incidental Crohn's pouches may be diagnosed early or late period post-IPAA. Crohn's may manifest within the pouch, in the proximal small bowel, and/or distally in the rectal cuff or anus. Like intestinal Crohn's, Crohn's disease of the pouch may be of an inflammatory, fibrostenosing, or fistulizing phenotype. Treatment depends on the phenotype and includes medical treatment, most commonly in the form of tumor necrosis factor inhibitor medications; however, the newer small molecules offer a potential treatment for these patients. Surgery first entails treating the sequelae of Crohn's and is typically staged. In up to 60% of Crohn's pouches, particularly in fistulizing disease and/or recalcitrant perianal disease, the pouch fails and must be defunctioned or excised. In patients with Crohn's pouches in situ long term, outcomes including quality of life are comparable to patients who underwent IPAA for UC.

    Abstract Complete mesocolic excision (CME) of colon cancer is a resection performed along embryological planes to include the completely intact mesentery surrounding the tumour with a high central vascular ligation. The aim is to remove all lymph nodes draining the cancer. Proponents of the technique cite the significantly decreased local recurrence and improved 5-year survival rates associated with CME versus conventional colectomy. Although increasingly performed in many centres, it has not yet gained widespread acceptance as it is technically more challenging and can incur an increased bleeding risk. A man in his 80s underwent a conventional right hemicolectomy for a pT4aN2aM0 ascending colon cancer at another institution. This was followed by chemotherapy. He presented to our institution 2 years later with an isolated 3.7×3.2 cm mesenteric tumour adjacent to his anastomosis. There was no intraluminal recurrence. He then underwent a repeat extended right colectomy with CME. Pathology confirmed lymph node recurrence. His case demonstrates the importance of CME in reducing carcinoma recurrence risk.

    Abstract Background: A prospective IDEAL stage 2a pilot study was carried out at a tertiary care center to evaluate the reliability of a homemade laparoscopic endotrainer, following the MISTEL and IDEAL framework guidelines.
    Methods: The validated modified (MISTELS) score was used to test the reliability of a low-cost laparoscopic trainer with commonly found components built by surgeons. Basic household materials including a cellular phone (camera source), wifi (linking source) and freely available webcam apps were used for construction. Five basic laparoscopic skills were performed by general surgery resident volunteers with minimal (1-6 months') laparoscopic surgery experience and tested and retested based on efficiency and precision. To determine interrater reliability, two trained observers scored all subjects. The Cronbach alpha test was used to test for internal consistency between tasks. The Interclass correlation coefficient is used for test and retest reliability.
    Results: 15 (80% male, mean age 28 ± 5 years) residents were included. The interrater and test-retest reliabilities for the total scores of the basic laparoscopic skills tests were 0.952 (95% CI, 0.895-0.981) and 0.64 (95% CI, 0.35-0.77), respectively. The Cronbach Alpha for the first assessment test and retest was 0.83. The MISTELS metrics had excellent reliability, exceeding the threshold level of 0.8.
    Conclusion: It is possible to assemble a low-cost, reliable trainer at home to enhance laparoscopic skills during residency.

    Abstract Background: The laparoscopic approach for colon cancer has become widely accepted. However, its safety for T4 tumors, and particularly for T4b tumors when local invasion to adjacent structures occurs, remains controversial. This study aimed to compare short and long-term outcomes in patients undergoing laparoscopic vs. open resection for T4a and T4b colon cancers.
    Methods: A prospectively maintained, single-institution database was queried to identify patients with pathological stage T4a and T4b colon adenocarcinomas electively operated on between 2000 and 2012. Patients were divided into two groups based on the use of laparoscopy. Patient characteristics, perioperative, and oncologic outcomes were compared.
    Results: One hundred and nineteen patients [41 laparoscopic (L), 78 open surgeries (O)] met the inclusion criteria. No difference was observed in age, gender, BMI, ASA, and procedure between groups. Tumors treated by L were smaller than O (p = 0.003). No difference was observed in morbidity, mortality, reoperation, or readmission between the groups. Length of hospital stay was shorter in L than O (6 vs. 9 days, p = 0.005). Conversion to open was necessary in 22% of all T4 tumors laparoscopic cases. However, when tumors were subdivided by pT4 classification, conversion was necessary for 4 of 34 (12%) pT4a patients vs. 5 of 7 (71%) pT4b patients (p = 0.003). In the pT4b cohort (n = 37), more tumors were treated by the open approach (30 vs. 7). For pT4b tumors, the R0 resection rate was 94% (86% in L vs. 97% in O, p = 0.249). The use of laparoscopy did not impact overall survival, disease-free survival, cancer-specific survival, or tumor recurrence overall in all T4 or T4a and T4b tumors.
    Conclusions: Laparoscopic surgery can be safely performed in pT4 tumors with similar oncologic outcomes as compared to open surgery. However, for pT4b tumors, the conversion rate is very high. The open approach may be preferable.

    Abstract Purpose: Previously considered a disease of old age, diverticular disease is increasingly prevalent in younger populations. Guidelines on surgical resection have shifted from recommending resection for all young onset patients to an individualized approach. Therefore, we aim to determine demographics and outcomes including radiographic and surgical recurrence rates in patients < 40 years old undergoing resection for diverticular disease.
    Methods: A retrospective, single center study was performed. All patients ≤ 39 years undergoing operative intervention for left-sided diverticular disease between Jan 2010 and July 2017 were included. Recurrence was determined by individual review of imaging and operative reports.
    Results: Overall, 147 (n = 107/72.8% male, mean age = 34.93 ± 4.12 years) patients were included. The majority were ASA 1 or 2 (n = 41/27.9% and n = 82/55.8%). The most common surgical indication was uncomplicated diverticulitis (n = 77, 52.4%) followed by perforation (n = 26/17.7%). The majority (n = 108/73.5%) of cases were elective. Seventy-nine (57.3%) of all cases were performed laparoscopically. Primary anastomosis without diversion was the most common surgical outcome (n = 108/73.5%). Median length of stay was 5 (4, 7) days. There was no mortality. There were three (2.0%) intraoperative and 38 (25.9%) postoperative complications. The most common complication was anastomotic leak (n = 6/4.1%). The majority (n = 5) of leaks occurred after elective surgery. Two neoplastic lesions (1.3% of cohort) were found (1 adenoma with low-grade dysplasia/1 polyp cancer). Over a mean follow-up of 96 (74, 123) months, only 2 (1.3%) patients experienced a surgical or radiological recurrence.
    Conclusion: Both neoplasia and recurrence after resection for diverticular disease in young onset patients are rare. Leaks after primary anastomosis even in the elective setting warrant careful consideration of a defunctioning ileostomy.

    Abstract Background: Tissue harvesting at the time of surgery offers surgeons and scientists a unique opportunity to discover and better understand disease pathophysiology. Tissue biobanking presents challenges in patient consents, specimen collection, preparation, and storage, but the potential for scientific discovery justifies the effort. Although the number of tissue biobanks is increasing worldwide, information regarding necessary infrastructure, process flow, and management of expected obstacles is lacking.
    Objective: To provide a framework and motivation for clinician scientists intending to start an intestinal tissue biobank under their direction.
    Data sources: The Carlino Family Inflammatory Bowel and Colorectal Diseases Biobank is housed at the Milton S. Hershey Medical Center.
    Study selection: Review.
    Intervention: Implementation of a surgical tissue biobank at a large tertiary care institution.
    Main outcome measures: Assess critical challenges and obstacles over the years as well as keys to the success of the program.
    Results: Over 2 decades, the institutional biobank grew from an IBD biobank to one which now incorporates thousands of surgical specimens representing numerous colorectal diseases. This was done through a process of refinement focusing on patient recruitment and an efficient consenting and specimen management process. The biobank's success is further insured by institutional, external, and philanthropic support; scientific collaborations; and sharing of biological specimens with other groups of dedicated researchers.
    Limitations: This is a single-center experience in collecting surgically resected colorectal specimens.
    Conclusions: Surgical specimen biobanks are essential in studying disease cause using genomics, transcriptomics, and proteomic technologies. Therefore, surgeons, clinicians, and scientists should build biobanks at their institutions to promote further scientific discovery and improve specimen diversity.
