The SAGES MASTERS program presents: the 10 seminal articles for the Laparoscopic Right Colectomy Pathway.

Background: As one of the 12 clinical pathways of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program, the Colorectal Pathway intends to deliver didactic content organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure (laparoscopic right colectomy, laparoscopic left/sigmoid colectomy, and intracorporeal anastomosis during minimally invasive (MIS) ileocecal or right colon resection). In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic right colectomy which surgeons should be familiar with.

Methods: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic right colectomy were identified, reviewed, and ranked by the SAGES Colorectal Task Force and invited subject experts.

Robotic Surgery for Ulcerative Colitis.

Subtotal colectomy (STC) or total proctocolectomy (TPC) and ileal pouch-anal anastomosis (IPAA) performed in two or three stages remain the procedure of choice for patients with ulcerative colitis (UC). Minimally invasive laparoscopic approaches for STC and IPAA have been established for over a decade, having been shown to reduce postoperative pain, length of stay, and improve fertility. However "straight-stick" laparoscopy has ergonomic and visual disadvantages in the pelvis, which may contribute to IPAA failure.

Robotic ileocolic resection with intracorporeal anastomosis for Crohn's disease.

The robotic platform can overcome limitations of the laparoscopic approach, particularly in the facilitation of intracorporeal anastomosis creation. We aim to share our institutional experience with robotic ileocolic resection for Crohn's disease (CD) and compare it to a laparoscopic cohort. We identified patients who underwent ileocolic resection for CD with a purely robotic (R) or laparoscopic (L) approach between February 2015 and 2018.

Attenuated familial adenomatous polyposis (AFAP) in a patient associated with a novel mutation in APC.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome associated with mutation in the adenomatous polyposis coli (APC) gene, a tumour suppressor located on chromosome 5q21. Attenuated familial adenomatous polyposis (AFAP) is a variant associated with fewer and later onset of colon polyps. AFAP-associated APC mutations have largely been found before codon 157, in exon 9 or after codon 1595.

Alvimopan for the Prevention of Postoperative Ileus in Inflammatory Bowel Disease Patients.

Background: Postoperative ileus (POI) is a temporary delay of coordinated intestinal peristalsis. Alvimopan, an oral peripherally acting mu-opioid receptor antagonist approved for accelerating gastrointestinal recovery, has never been studied specifically in patients with inflammatory bowel disease (IBD).

Aim: To investigate the efficacy of alvimopan in preventing POI among IBD patients.

Crohn's Disease of the Esophagus, Duodenum, and Stomach.

Upper gastrointestinal Crohn's is an under-reported, under-recognized phenotype of Crohn's disease. Routine screening in the pediatric population has shown a higher prevalence compared with adults; however, most adult patients remain asymptomatic with respect to upper gastrointestinal Crohn's disease. For the patients who are symptomatic, medical treatment is the first line of management, except for cases of obstruction, perforation, or bleeding.

Robotic transanal minimally invasive rectal mucosa harvest.

Introduction: Buccal mucosal grafts (BMG) are traditionally used in urethral reconstruction. There may be insufficient BMG for applications requiring large grafts, such as urethral stricture after gender-affirming phalloplasty. Rectal mucosa in lieu of BMG avoids oral impairment, while potentially affording less postoperative pain and larger graft dimensions.

Early experience with urgent robotic subtotal colectomy for severe acute ulcerative colitis has comparable perioperative outcomes to laparoscopic surgery.

It has been established that patients undergoing subtotal colectomy for UC benefit from a minimally invasive approach, despite the longer operating times associated with laparoscopic surgery when compared to open surgery (Andersson and Söderholm in Dig Dis 27(3):335-340, 2009; Telem et al. in Surg Endosc 24(7):1616-1620, 2010; Wu et al. in Int J Colorectal Dis 25(8):949-957, 2010).

Multi-Institutional Outcomes of Minimally Invasive Harvest of Rectal Mucosa Graft for Anterior Urethral Reconstruction.

Purpose: We report multi-institutional outcomes in patients who underwent urethroplasty with a rectal mucosa graft.

Materials And Methods: We used the TURNS (Trauma and Urologic Reconstructive Network of Surgeons) database to identify patients who underwent urethral reconstruction with transanal harvest of a rectal mucosa graft. We reviewed preoperative demographics, stricture etiology, previous management and patient outcomes.

Factors Associated with Short-Term Morbidity in Patients Undergoing Colon Resection for Crohn's Disease.

Background: Patients undergoing colon resection for Crohn's disease are at risk of developing postoperative complications. The aim of this study is to identify factors associated with short-term (30-day) morbidity in patients undergoing colon resection for Crohn's disease from a national database.

Methods: Patients who underwent colon resection for Crohn's disease in 2015 were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

Functional outcomes and quality of life after anorectal surgery.

There is a paucity of information examining quality of life (QOL) and functional results after anorectal surgery. We aim to prospectively evaluate postoperative QOL, pain, functional outcomes, and satisfaction for a large cohort of patients undergoing anorectal surgery. Data were prospectively accrued for consecutive patients undergoing anorectal operations from June 2009 to September 2010.

Current surgical management of ulcerative colitis.

Inflammatory bowel disease is divided into 2 major disease entities: Crohn's disease and ulcerative colitis. Ulcerative colitis is characterized by contiguous inflammation of the colorectal mucosa, always beginning in and involving the rectum and progressing for variable distances proximally within the colon. In ulcerative colitis, medical therapy, which is not curative, is directed at controlling symptoms and reducing the underlying inflammatory process.

Prospective analysis of clinician accuracy in the diagnosis of benign anal pathology: comparison across specialties and years of experience.

Purpose: The majority of patients referred to a colorectal surgeon with anal complaints are told they have "hemorrhoids"; however, many of these patients have other anal pathology causing their symptoms. Therefore, we prospectively evaluated the diagnostic accuracy of physicians for common anal pathology, stratified by specialty and experience.

Methods: Seven common benign anal pathologic conditions were selected (prolapsed internal hemorrhoid, thrombosed external hemorrhoid, abscess, fissure, fistula, condyloma acuminata, and full-thickness rectal prolapse).

Does anatomic versus nonanatomic resection affect recurrence and survival in patients undergoing surgery for colorectal liver metastasis?

Anatomic resection of colorectal liver metastases may offer a survival advantage because (1) it removes the hepatic functional unit as a whole and (2) nonanatomic resection has been reported to have a higher incidence of positive margins.A retrospective review was performed of patients undergoing hepatic resection for colorectal liver metastases. 183 patients met inclusion criteria of undergoing either anatomic or nonanatomic resection with the aim of removing all gross disease.

Granulomatous enterocolitis associated with Hermansky-Pudlak syndrome.

Background: Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder. It consists of a triad of tyrosinase-positive oculocutaneous albinism (Ty-pos OCA), bleeding diathesis resulting from platelet dysfunction, and systemic complications associated with accumulation of ceroid lipofuscin. Many patients are from a small area in northwestern Puerto Rico.

Restorative proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis after liver transplant for primary sclerosing cholangitis: case report and review of literature.

Primary sclerosing cholangitis (PSC) is present in 5 per cent of patients with ulcerative colitis (UC). Conversely, as many as 90 per cent of patients with PSC have been found to have UC. The accepted treatment for advanced PSC is orthotopic liver transplant, and the treatment of ulcerative colitis with concomitant PSC is restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA).
