Meta-Analysis Review
BACKGROUND
Temporary faecal diversion is sometimes used for management of refractory perianal Crohn's disease (CD) with variable success.
AIMS
To perform a systematic review with meta-analysis to evaluate the effectiveness, long-term outcomes and factors associated with success of temporary faecal diversion for perianal CD.
METHODS
Through a systematic literature review through 15 July 2015, we identified 16 cohort studies (556 patients) reporting outcomes after temporary faecal diversion. We estimated pooled rates [with 95% confidence interval (CI)] of early clinical response, attempted and successful restoration of bowel continuity after temporary faecal diversion (without symptomatic relapse), and rates of re-diversion (in patients with attempted restoration) and proctectomy (with or without colectomy and end-ileostomy). We identified factors associated with successful restoration of bowel continuity.
RESULTS
On meta-analysis, 63.8% (95% CI: 54.1-72.5) of patients had early clinical response after faecal diversion for refractory perianal CD. Restoration of bowel continuity was attempted in 34.5% (95% CI: 27.0-42.8) of patients, and was successful in only 16.6% (95% CI: 11.8-22.9). Of those in whom restoration was attempted, 26.5% (95% CI: 14.1-44.2) required re-diversion because of severe relapse. Overall, 41.6% (95% CI: 32.6-51.2) of patients required proctectomy after failure of temporary faecal diversion. There was no difference in the successful restoration of bowel continuity after temporary faecal diversion in the pre-biological or biological era (13.7% vs. 17.6%, P = 0.60), in part due to selection bias. Absence of rectal involvement was the most consistent factor associated with restoration of bowel continuity.
CONCLUSIONS
Temporary faecal diversion may improve symptoms in approximately two-thirds of patients with refractory perianal Crohn's disease, but bowel restoration is successful in only 17% of patients.

World Journal of Surgical Oncology Mar 2022To assess the efficacy of extraperitoneal colostomy (EPC) in preventing stoma-related complications. (Meta-Analysis)
Meta-Analysis
AIM
To assess the efficacy of extraperitoneal colostomy (EPC) in preventing stoma-related complications.
BACKGROUND
Transperitoneal colostomy (TPC) is a widely used surgical approach. However, TPCs have been reported to have increased risks of stoma-related complications, such as parastomal hernias, stomal retraction, and stomal prolapse. The purpose of EPC is to reduce these complications. However, there is still a lack of evidence-based studies.
MATERIALS AND METHODS
MEDLINE, EMBASE, Web of Science, Scopus, MOOSE, PubMed, Google Scholar, Baidu Scholar, and the Cochrane Library were searched to conduct a systematic review and meta-analysis with RCTs. The meta-analysis was performed with RevMan 5.4 software.
RESULTS
This study included 5 eligible RCTs. Compared with the TPC group, the EPC group had lower incidence rates of parastomal hernias (RR, 0.14; 95% CI, 0.04-0.52, P = 0.003, I = 0%) and stomatal prolapse (RR, 0.27; 95% CI, 0.08-0.95, P = 0.04, I = 0%), but a higher rate of defecation sensation (RR, 3.51; 95% CI, 2.47-5.0, P < 0.00001, I = 37%). No statistically significant differences were observed in stoma retraction, colostomy construction time, stoma ischemia, or stoma necrosis.
CONCLUSION
Extraperitoneal colostomies are associated with lower rates of postoperative complications than transperitoneal colostomies. A randomized controlled trial meta-analysis found that permanent colostomies after abdominoperineal resection resulted in better outcomes.

Meta-Analysis
Colorectal cancer (CRC) is a leading cause of morbidity and mortality. Post-CRC resection complications and lower quality of life (QoL) are associated with a lower long-term survival. Perioperative administration of probiotics/synbiotics might lower prevalence of side effects and improve QoL and survival among CRC patients. Medline, Web of Science, Cochrane database, Embase, and clinical trials registries were searched in January 2020. Altogether, 16 randomized placebo-controlled probiotic/synbiotic clinical trials that included patients undergoing CRC surgery and investigated postoperative complications and QoL side effects were found. Meta-analyses using random-effects model were performed on data from 11 studies to calculate the effects of probiotics/synbiotics on common CRC resection postoperative side effects and complications. Perioperative probiotics/synbiotics administration was associated with lower infection incidence (odds ratio [OR] = 0.34, P < 0.001), lower diarrheal incidence (OR = 0.38, P < 0.001), faster return to normal gut function (mean difference [MD] -0.66 days, P < 0.001), shorter postoperative antibiotics use (MD -0.64 days, P < 0.001), lower incidence of septicemia (OR = 0.31, P < 0.001), and shorter length of hospital stay (MD -0.41 days, P = 0.110). The results support the hypothesis that short-term perioperative administration of probiotics/synbiotics, which are easy to administer, have few side-effects, and are low cost compared with alternatives, might help to alleviate gastrointestinal symptoms and postoperative complications among CRC patients.

Comparative Study Meta-Analysis
Surgical resection is crucial for curative treatment of rectal cancer. Through multidisciplinary treatment, including radiochemotherapy and total mesorectal excision, survival has improved substantially. Consequently, more patients have to deal with side effects of treatment. The most recently introduced surgical technique is robotic-assisted surgery (RAS) which seems equally effective in terms of oncological control compared to laparoscopy. However, RAS enables further advantages which maximize the precision of surgery, thus providing better functional outcomes such as sexual function or contience without compromising oncological results. This review was done according to the PRISMA and AMSTAR-II guidelines and registered with PROSPERO (CRD42018104519). The search was planned with PICO criteria and conducted on Medline, Web of Science and CENTRAL. All screening steps were performed by two independent reviewers. Inclusion criteria were original, comparative studies for laparoscopy vs. RAS for rectal cancer and reporting of functional outcomes. Quality was assessed with the Newcastle-Ottawa scale. The search retrieved 9703 hits, of which 51 studies with 24,319 patients were included. There was a lower rate of urinary retention (non-RCTs: Odds ratio (OR) [95% Confidence Interval (CI)] 0.65 [0.46, 0.92]; RCTs: OR[CI] 1.29[0.08, 21.47]), ileus (non-RCTs: OR[CI] 0.86[0.75, 0.98]; RCTs: OR[CI] 0.80[0.33, 1.93]), less urinary symptoms (non-RCTs mean difference (MD) [CI] - 0.60 [- 1.17, - 0.03]; RCTs: - 1.37 [- 4.18, 1.44]), and higher quality of life for RAS (only non-RCTs: MD[CI]: 2.99 [2.02, 3.95]). No significant differences were found for sexual function (non-RCTs: standardized MD[CI]: 0.46[- 0.13, 1.04]; RCTs: SMD[CI]: 0.09[- 0.14, 0.31]). The current meta-analysis suggests potential benefits for RAS over laparoscopy in terms of functional outcomes after rectal cancer resection. The current evidence is limited due to non-randomized controlled trials and reporting of functional outcomes as secondary endpoints.

INTRODUCTION
Abdominoperineal resection is associated with a high rate of wound complications. A high degree of wound tension, a common contributor to wound breakdown and complications, may be mitigated by incisional negative-pressure wound therapy (NPWT). Although NPWT has been shown to reduce complications associated with open and complex wounds, there is a paucity of data regarding its prophylactic use for incisional wounds.
OBJECTIVE
To determine the effect of NPWT use on surgical wound complications of abdominoperineal resection for malignancy.
METHODS
We performed a systematic review by querying the PubMed database for studies from 1990 to 2019 and included English-language studies that used incisional NPWT for closed wounds from abdominoperineal resection in malignancy cases.
RESULTS
Five studies with a total of 76 patients were included. Their findings showed reduced rates of surgical site complications with the use of incisional NPWT. Another 2 studies describing the use of prophylactic NPWT to expedite secondary closure of the surgical wound followed by incisional wound therapy were separately categorized and included 8 patients, none of whom experienced wound wound complications.
DISCUSSION
Additional, prospective research is needed to confirm the benefit of prophylactic incisional NPWT.

Review
The role of perineal application of prophylactic negative-pressure wound therapy for prevention of wound-related complications after abdomino-perineal resection: a systematic review.
BACKGROUND
Closed perineal wounds often fail to heal by primary intention after abdomino-perineal resection (APR) and are often complicated by surgical site infection (SSI) and/or wound dehiscence. Recent evidence showed encouraging results of prophylactic negative-pressure wound therapy (pNPWT) for prevention of wound-related complications in surgery. Our objective was to gather and discuss the early existing literature regarding the use of pNPWT to prevent wound-related complications on perineal wounds after APR.
METHODS
Medline, Embase, and Web of Science were searched for original publications and congress abstracts reporting the use of pNPWT after APR on closed perineal wounds.
RESULTS
Seven publications were included for analysis. Two publications reported significantly lower incidence of SSI in pNPWT patients than in controls with a risk reduction of about 25-30%. Two other publications described similar incidences of SSI between the two groups of patients but described SSI in pNPWT patients to be less severe. One study reported significantly lower incidence of wound dehiscence in pNPWT patients than in controls.
CONCLUSION
The largest non-randomized studies investigating the effect of pNPWT on the prevention of wound-related complications after APR showed encouraging results in terms of reduction of SSI and wound dehiscence that deserve further investigation and confirmation.

Review
INTRODUCTION
The laparoscopic-assisted abdominoperineal resection (LAPR) has been proved to be associated with a shorter postoperative recovery, with equivalent oncological results and similar survival when compared with conventional open surgery, for patients with low rectal cancer.
METHOD
Case report of a massive intraoperative bleeding during LAPR and systematic review of the English language literature, using PubMed Medline, ISI Thopmson, OVID and EMBASE databases.
RESULTS
58 years old patient admitted in emergency setting or rectal bleeding. Rectal examination revealed a protruding,frail tumor, located 2 cm from the anal verge. Total colono scopy revealed an infiltrative, protruding tumor, situated at 2 cm from the anal verge, with a 5 cm cranial extension,without any additional colonic lesions. Computed Tomography showed a 4,5 cm circumferential rectal wall thickening, without any enlarged mesorectal or abdominal lymph nodes. The patient was transported to operating room for a LAPR. During final hemostasis, at the level of perineal surgical wound, an acute massive bleeding occurred from the presacral vessels with severe blood loss. This bleeding couldnot be managed laparo scopicaly and conversion to laparotomywas decided, with pelvic packing. At 48 hours after the initial surgical approach, the tamponing packs were removed, without signs of active bleeding. There were applied haemostatic agents and the perineal wound was sutured, without further rbleeding during in-hospital stay.
CONCLUSIONS
A rapid and effective control of the presacral bleeding is mandatory to prevent a fatal outcome. Pelvic packing remains a life-saving procedure and the treatment of choice in severe cases.

Meta-Analysis
PURPOSE
Transanal minimally invasive surgery has theoretical advantages for ileal pouch-anal anastomosis surgery. We performed a systematic review assessing technical approaches to transanal IPAA (Ta-IPAA) and meta-analysis comparing outcomes to transabdominal (abd-IPAA) approaches.
METHODS
Three databases were searched for articles investigating Ta-IPAA outcomes. Primary outcome was anastomotic leak rate. Secondary outcomes included conversion rate, post operative morbidity, and length of stay (LoS). Staging, plane of dissection, anastomosis, extraction site, operative time, and functional outcomes were also assessed.
RESULTS
Searches identified 13 studies with 404 unique Ta-IPAA and 563 abd-IPAA patients. Anastomotic leak rates were 6.3% and 8.4% (RD 0, 95% CI -0.066 to 0.065, p = 0.989) and conversion rates 2.5% and 12.5% (RD -0.106, 95% CI -0.155 to -0.057, p = 0.104) for Ta-IPAA and abd-IPAA. Average LoS was one day shorter (MD -1, 95% CI -1.876 to 0.302, p = 0.007). A three-stage approach was most common (47.6%), operative time was 261(± 60) mins, and total mesorectal excision and close rectal dissection were equally used (49.5% vs 50.5%). Functional outcomes were similar. Lack of randomised control trials, case-matched series, and significant study heterogeneity limited analysis, resulting in low to very low certainty of evidence.
CONCLUSIONS
Analysis demonstrated the feasibility and safety of Ta-IPAA with reduced LoS, trend towards less conversions, and comparable anastomotic leak rates and post operative morbidity. Though results are encouraging, they need to be interpreted with heterogeneity and selection bias in mind. Robust randomised clinical trials are warranted to adequately compare ta-IPAA to transabdominal approaches.

(Meta-Analysis)
Meta-Analysis
BACKGROUND
A subset of patients who undergo total proctocolectomy with ileal pouch-anal anastomosis (IPAA) creation for ulcerative colitis (UC) will later develop Crohn's disease (CD) of the pouch, which has been associated with significant morbidity. We aimed to analyze the incidence of CD of the pouch and to review the existing diagnostic criteria utilized.
METHODS
A systematic search performed through March 1, 2018, identified 12 studies that reported the incidence of CD of the pouch after IPAA for UC or indeterminate colitis (IC). We compiled all diagnostic criteria utilized in these studies and then performed a meta-analysis using random effects modeling to estimate the overall incidence of CD of the pouch in this population.
RESULTS
Among 4843 patients with an IPAA for UC or IC, 10.3% of patients were ultimately diagnosed with CD of the pouch (95% confidence interval [CI], 6.1%-15.4%). The most commonly reported diagnostic criteria were (1) presence of fistula/fistulae, (2) stricture involving the pouch or prepouch ileum, and (3) presence of prepouch ileitis. In a secondary analysis, excluding those studies that included patients with a preoperative diagnosis of IC, the incidence of CD of the pouch was 12.4% (95% CI, 9.0%-16.1%).
CONCLUSIONS
The estimated incidence of 10.3% will assist gastroenterologists and surgeons in preoperative counseling regarding the potential to develop CD of the pouch. There is an unmet need for common diagnostic criteria for a more standardized approach to the diagnosis of CD of the pouch.

Comparative Study Meta-Analysis
BACKGROUND
Neoadjuvant chemoradiotherapy (nCRT) before total mesorectal excision (TME) and followed systemic chemotherapy is widely accepted as the standard therapy for locally advanced rectal cancer (LARC). This meta-analysis was to evaluate the current evidence regarding nCRT in combination with induction or consolidation chemotherapy for rectal cancer in terms of oncological outcomes.
METHODS
A systematic search of medical databases (PubMed, EMBASE and Cochrane Library) was conducted up to the end of July 1, 2021. This meta-analysis was performed to evaluate the efficacy of TNT in terms of pathological complete remission (pCR), nCRT or surgical complications, R0 resection, local recurrence, distant metastasis, disease-free survival (DFS) and overall survival (OS) in LARC.
RESULTS
Eight nRCTs and 7 RCTs, including 3579 patients were included in the meta-analysis. The rate of pCR was significantly higher in the TNT group than in the nCRT group, (OR 1.85, 95% CI 1.39-2.46, p < 0.0001), DFS (HR 0.80, 95% CI 0.69-0.92, p = 0.001), OS (HR 0.75, 95% CI 0.62-0.89, p = 0.002), nCRT complications (OR 1.05, 95% CI 0.77-1.44, p = 0.75), surgical complications (OR 1.02, 95% CI 0.83-1.26, p = 0.83), local recurrence (OR 1.82, 95% CI 0.95-3.49, p = 0.07), distant metastasis (OR 0.77, 95% CI 0.58-1.03, p = 0.08) did not differ significantly between the TNT and nCRT groups.
CONCLUSION
TNT appears to have advantages over standard therapy for LARC in terms of pCR, R0 resection, DFS, and OS, with comparable nCRT and postoperative complications, and no increase in local recurrence and distant metastasis.
