Caudal duplication syndrome is a rare association of anatomical anomalies describing duplication of the hindgut, spine, and uro-genital structures, leading to varied clinical presentations. The current literature focuses on case reports which describe the embryological etiology and anatomical spectrum of the condition giving little attention to the surgical preparation, the need for a well-structured follow-up program, or the transition into adult healthcare of these complex patients. No reviews have been published regarding this complex pathology. : A review of caudal duplication syndrome cases was done to assess the range of the clinical malformations, timing, and types of surgical interventions. Inconsistencies in multidisciplinary care, follow-up, and risk events were described. Hindgut duplication always involved the anorectal region. Anorectal malformations were evenly distributed as unilateral and bilateral. Colon duplication extended from the anal region to the transverse colon or ascending colon in most of the cases and less to terminal. In females, genital duplication was present in all cases. The follow-up period varied between 3 months and 12 years. In all adult females, the motive of presentation was related to pregnancy (complications after successful delivery, fertility evaluation) or late complications (fecalith obstruction of the end-to-side colon anastomosis, repeated UTIs with renal scarring). : Complex malformations affecting multiple caudal organs may have a strong impact in many aspects of the long-term quality of life; therefore, patients with caudal duplication syndrome need increased awareness and joined multidisciplinary treatment.

Comparative Study Meta-Analysis
BACKGROUND
Minimally invasive colectomy has become the standard for treatment of colonic disease in many centers. Restoration of bowel continuity following resection can be achieved by intracorporeal (IC) or extracorporeal (EC) anastomosis. The aim of this systematic review was to assess the outcomes of IC compared to EC anastomosis in minimally invasive right colectomy.
METHODS
A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant systematic literature search for studies assessing the outcome of IC and EC anastomosis in laparoscopic and robot-assisted right colectomy was conducted. The primary outcome of this review was postoperative complications. Secondary outcomes included operative time, blood loss, length of stay, conversion to open surgery, and bowel recovery.
RESULTS
Twenty-five studies including 4450 patients were evaluated. 47.7% of patients had IC anastomosis and 52.3% had EC anastomosis. The weighted mean length of extraction site incision in the IC group was shorter than the EC group. The EC group had significantly higher odds of conversion to open surgery (OR 1.87, 95% CI 1-3.45, p = 0.046), total complications (OR 1.54, 95% CI 1.05-2.11, p = 0.007), anastomotic leakage (AL) (OR 1.95, 95% CI 1.4-2.7, p = 0.003), surgical site infection (SSI) (OR 1.69, 95% CI 1.4-2.6, p = 0.002), and incisional hernia (OR 3.14, 95% CI 1.85-5.33, p < 0.001) compared to the IC group. Both groups had similar rates of ileus, small bowel obstruction, bleeding, and intra-abdominal infection.
CONCLUSION
IC anastomosis was associated with significantly shorter extraction site incisions, earlier bowel recovery, fewer complications, and lower rates of conversion, AL, SSI, and incisional hernia than has the EC anastomosis.

There are currently no guidelines on the long-term management of patients after an episode of acute ischaemic colitis. Our aim was to review the literature on the pattern of presentation and the pathophysiology of this condition and to understand the current status of the acute and long-term management of ischaemic colitis. Furthermore, we aim to provide recommendations for the clinicians in regard to the acute and long-term management of ischaemic colitis. A review of the English literature over the last 15 years was performed using Embase and Medline. Search terms were ischaemic OR ischemic, colitis OR colon. Two reviewers screened the papers against pre-determined eligibility criteria. A senior consultant surgeon performed a final overview. Three hundred sixty-eight papers were identified on the initial search; 318 were irrelevant and 17 were conference abstracts; both were excluded. Thirty-three full articles were assessed for suitability; nine were further excluded. Twenty-four articles were included in the final analysis and cross-referenced against those listed in the systematic reviews. There is a large clinical heterogeneity in inclusion criteria (histological, radiological, endoscopic, surgical specimen). Twelve out of 24 articles included patients only based on histological diagnosis. The definition of right and left (or nonright) ischaemic colitis was variable based on whether hepatic or splenic flexure was used as the cut-off point. Five retrospective case series highlighted that patients with isolated right-sided ischaemic colitis had a worse prognosis than those with left-sided colitis (higher mortality, need for surgery, length of hospital stay). The overall recurrence was 9%. There is a need for a higher-level evidence to guide clinicians on the long-term management of patients following an episode of acute colonic ischaemia. Further evidence is required to determine whether right colonic ischaemia should be managed differently from left.

PURPOSE
During right-sided colectomies, surgeons encounter major anatomical variations at the level of the right colon, leading to morbidity. Due to the confusion surrounding the colonic arterial vessels emerging from the superior mesenteric artery (SMA) to vascularize the right part of the colon, this review aimed to describe the arterial vessels found in the mesocolic structures of the ascending colon, the hepatic flexure and the right transverse colon.
METHODS
A review of the literature was performed using the MEDLINE database. Only human studies were included. All dissection, angiographic, arterial cast and corrosion studies were analyzed.
RESULTS
This review demonstrates that the right colon, the hepatic flexure and the right transverse colon are vascularized by three significant arteries emerging from the SMA and forming one peripheral paracolic arc: (1) the ileocolic artery (ICA), the most constant vessel (99.8%) with low variability; (2) the right colic artery (RCA), the most inconstant vessel (2/3 of cases) with high variability in its origin; and (3) the middle colic artery (MCA), a constant vessel (95%) with variation in its origin and its number. The marginal artery is almost constant (100%) and represents the only peripheral arterial arc at the level of the right side of the colon.
CONCLUSIONS
Three arteries emerging from the superior mesenteric artery exist: the ICA, the RCA and the MCA. The ICA and the MCA are the most constant. Knowledge of this vascular anatomy is essential for performing right-sided colectomies.

Comparative Study Meta-Analysis
OBJECTIVE
Location of the primary tumor side has become an increasingly prognostic factor for colorectal liver metastasis. The present study was to perform a meta-analysis to investigate if primary right-sided tumor impacted on long-term survival outcome of colorectal liver metastases following local treatment.
METHOD
Eligible trials were identified from the Embase, PubMed, Web of Science and the Cochrane database that were published before October in 2018. English language trials that compared long-term survival outcome of primary left-sided tumor with right-sided tumor colorectal liver metastases following local treatment were included. Hepatic resection for colorectal liver metastases was investigated. The main study outcomes included overall survival and disease free survival of primary right-sided colorectal liver metastases following local treatment. The risk factors of largest tumor size, primary node metastases, multiple tumor and RAS mutation were also analyzed. A systematic review and meta-analysis was done using a fixed-effects model. Hazard ratio with a 95% confidence interval was used to measure the pooled effect.
RESULTS
A total of twelve studies with 6387 patients were included. For primary right-sided colorectal liver metastases patients following hepatic resection, the overall pooled HR for 5-year overall survival rate was 1.354 (95% CI: 1.238-1.482; p = 0.000; I = 33.7%, p = 0.138). The pooled HR for 5-year disease free survival rate of primary right-sided CRLM in the included studies calculated using the fix-effects model was 1.104 (95% CI: 0.987-1.235; p = 0.084; I = 0%, p = 0.477).
CONCLUSION
It demonstrated that primary right-sided for colorectal liver metastases location was a significantly worse prognostic factor in terms of overall survival.
