BACKGROUND
Whether high or low ligation of the inferior mesenteric artery (IMA) is superior in surgery for rectal and sigmoid colon cancers remains controversial. Although several meta-analyses have been conducted, the level of lymph node clearance was poorly defined. We performed a meta-analysis comparing high and low ligation of the IMA for sigmoid colon and rectal cancers, with emphasis on high dissection of the lymph node at the IMA root in all the included studies.
METHODS
PubMed, MEDLINE, and EMBASE databases were searched to identify relevant articles published until 2020. The patient's perioperative and oncologic outcomes were analyzed. Statistical analysis was performed using the statistical software RevMan version 5.4.
RESULTS
A total of 17 studies, including four randomized controlled trials, published between 2011 and 2020 were selected. In total, 1,846 patients received low ligation of the IMA plus high dissection of lymph nodes (LL+HD), and 2,648 patients received high ligation of the IMA (HL). LL+HD was associated with low incidence of anastomotic leakage ( < 0.001), borderline long operative time ( = 0.06), and less yields of total lymph nodes ( = 0.03) but equivalent IMA root lymph nodes ( = 0.07); moreover, LL+HD exhibited non-inferior long-term oncological outcomes.
CONCLUSION
In comparison with HL, LL+HD was an effective and safe oncological procedure for sigmoid colon and rectal cancers. Therefore, to ligate the IMA below the level of the left colic artery with D3 high dissection for sigmoid colon and rectal cancers might be suggested once the surgeons are familiar with this technique.

To assess the efficacy and safety of micro-percutaneous nephrolithotomy (Microperc) and mini-percutaneous nephrolithotomy (Miniperc) in the treatment of moderately sized renal stones. Literature search of PubMed, Web of Science, and Embase was performed prior to January 2021. We used odds ratios (OR) and weighted mean difference (WMD) for dichotomous variables and continuous variables, respectively. Results were pooled using Review Manager version 5.3 software. A total of six studies involving 291 Microperc and 328 Miniperc cases was included. The overall stone-free rate (SFR) of Microperc was 87.29% (254/291), while the SFR of Miniperc was 86.59% (284/328). Microperc was associated with lower hemoglobin drop (WMD: -0.98; = 0.03) and higher renal colic requiring D-J stent insertion (OR: 3.49; = 0.01). No significant differences existed between Microperc and Miniperc with respect to SFR (OR: 1.10; = 0.69), urinary tract infection (OR: 0.38; = 0.18), operative time (WMD: -5.76; = 0.62), and hospital stay time (WMD: -1.04; = 0.07). Our meta-analysis demonstrated that Microperc could produce an SFR that was comparable with that of Miniperc. Microperc was associated with lower hemoglobin drop, while Miniperc was associated with lower renal colic rates. In addition, the operation time and hospital stay time for both these procedures were similar.

Complementary Therapies in Medicine Dec 2021To investigate evidence for the treatment of childhood colic by supplementing Lactobacillus reuteri in infants breastfed with breast milk. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To investigate evidence for the treatment of childhood colic by supplementing Lactobacillus reuteri in infants breastfed with breast milk.
METHODS
The study was conducted according to the PRISMA protocol. The databases used for acquiring data were PubMed and Web of Science, applying MeSH terms and free terms. Meta-analysis was conducted using Stata ™ 12.0. The risk of bias was evaluated by the Review Manager (RevMan) 5.3 tool, and the strength of evidence was assessed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE).
RESULTS
Ten clinical trials were included in the review. The administration of L. reuteri (DSM 17938 or ATCC55730) was tested in infants (n = 248) versus the control/placebo group (n = 229). Eight articles were included in the meta-analysis. There was a significant response in reducing crying time (minutes/day) and treatment effectiveness (reduction ≥ 50% in average daily crying time) in the first week (p = 0.001 and p = 0.003, respectively). These results were similar in the second, third weeks (p < 0.001 for both outcomes) and fourth weeks (p<0.001 and p = 0.002, respectively). The risk of bias was low for the majority of the studies. Confidence in evidence was considered very low for crying time and low for effectiveness treatment.
CONCLUSIONS
The evidence shows that the administration of Lactobacillus reuteri to babies fed with breast milk reduces the crying time in babies diagnosed with colic. But our confidence in the effect estimate is limited.

Review
BACKGROUND
Liposuction is among the most popular esthetic procedures worldwide. With growing demand and popularity, reports of serious complications accumulate. Despite being a rare complication of the procedure, visceral perforation is associated with morbidity and severe debilitation.
METHODS
The authors conducted a literature search for reported cases of perforation of abdominal viscera following liposuction procedures in the electronic databases of PubMed, Scopus and Cochrane Library databases.
RESULTS
The authors found 22 publications; 19 cases case reports and three studies, reporting a total of 49 cases of visceral perforation following abdominal liposuction procedures. Average age of patients was 50 years (range 24-72). Twenty-seven patients (73%) were female, and 10 were male (27%). Forty (81%) patients underwent isolated liposuction, and nine (19%) had multiple procedures carried out in a single surgery. Twenty patients (42%) had undergone previous abdominal surgery, 13 (27%) suffered abdominal wall weakness or deformities, and 7 (14%) suffered from obesity. 25 (52%) ileal perforations occurred, 6 jejunal (12.5%), 5 colic (10%) and 2 (4%) each of splenic and hepatic. Seven patients (14%) died during their hospitalization, 20 (41%) were discharged with no sequelae complications, and 22 (45%) developed complications after discharge.
CONCLUSIONS
Liposuction is a popular esthetic procedure that underwent numerous changes over the past century since its introduction. Despite its widely accepted reputation of a safe procedure with minimal complications, a growing number of reports on visceral perforation following liposuction have emerged. Scrupulous pre-operative evaluation and high index of suspicion are crucial for avoiding complications and unfavorable outcomes.

INTRODUCTION
The aim of this article was to cite rare but sometimes serious emergencies that may be encountered by any urologist during their practice, and to outline the main principles of their management.
MATERIAL AND METHOD
A systematic review of the literature using PubMed, Embase and Google Scholar was carried out between January 2000 and June 2021. The articles obtained were selected according to their age and type. The original articles, meta-analyses, recommendations and the most recent journal articles published in French and English have been retained. A total of 312 articles were identified and 58 selected from their abstracts. The articles were then analysed exhaustively by the authors, and 24 references were finally selected.
RESULTS
Several rare emergencies of an infectious nature (xanthogranulomatous pyelonephritis, emphysematous cystitis and pyelonephritis, malacoplasia, hydatiduria), ischemic nature (Fournier's gangrene, penile calciphylaxis), or hemorrhagic nature (hemospermia, hemorrhages of the upper urinary tract or adrenal gland spontaneous hematoma), or at the origin of painful manifestations (spermatic colic, venous thrombosis of the penis), can pose diagnostic and therapeutic difficulties, in the absence of consensus concerning their management.
CONCLUSION
These pathologies, rare but sometimes serious, must be recognized in order to not delay the treatment and to be able to reduce their morbidity and mortality. Combined with the constant improvement of our diagnostic and therapeutic arsenal, a better knowledge of these rare emergencies will help to preserve the functional and vital prognosis of patients.

Meta-Analysis Review
A systematic review and meta-analysis of variants of the branches of the superior mesenteric artery: the Achilles heel of right hemicolectomy with complete mesocolic excision?
AIM
Dissection with subsequent ligation and resection of arteries at their origin (central vascular ligation) is essential for adequate oncological resection during right hemicolectomy with complete mesocolic excision. This technique is technically demanding due to the highly variable arterial pattern of the right colon. Therefore, this study aims to provide a comprehensive evidence-based assessment of the arterial vascular anatomy of the right colon.
METHODS
A thorough systematic literature search through September 2020 was conducted on the electronic databases PubMed, Scopus and Web of Science to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using MetaXl software.
RESULTS
A total of 41 studies (n = 4691 patients) were included. The ileocolic artery (ICA), right colic artery (RCA) and middle colic artery (MCA) were present in 99.7% (95% CI 99.4%-99.8%), 72.6% (95% CI 61.3%-82.5%) and 96.9% (95% CI 94.2%-98.8%) respectively of patients. Supernumerary RCA and MCA were observed in 3.2% and 11.4% respectively of all cases. The RCA shared a common trunk with the ICA and MCA in 13.2% and 17.7% respectively of patients. A retro-superior mesenteric vein course of the ICA and RCA was observed in 55.1% and 11.4% respectively of all cases.
CONCLUSION
The vascular anatomy of the right colon displays several notable variations, namely the absence of some branches (RCA absent in 27.4% of cases), supernumerary branches, common trunks, and retro-superior mesenteric vein courses. These variations should be taken into consideration during right hemicolectomy with complete mesocolic excision to ensure adequate oncological resection while minimizing intra-operative complications.

Translational Andrology and Urology May 2021To determine whether previous unsuccessful shockwave lithotripsy (SWL) influence the outcomes of ureteroscopy (URS). (Review)
Review
BACKGROUND
To determine whether previous unsuccessful shockwave lithotripsy (SWL) influence the outcomes of ureteroscopy (URS).
METHODS
An exhaustive search of PubMed, EMBASE, Web of Science and Cochrane Library were conducted to find eligible studies before October 2020. Result variables consisting stone-free rate (SFR), operation time and postoperative modified Clavien grade I-IV complications were pooled utilizing RevMan 5.3.
RESULTS
Seven studies with 2413 individuals were included. Pooled results revealed that the salvage URS after failed SWL was similar to URS performed primarily regarding SFR [odds ratio (OR) =0.84, P=0.15] and operation time [weighted mean difference (WMD) =6.79, P=0.19]. Additionally, no statistically significant differences concerning fever (OR: 1.36; P=0.32), hematuria (OR: 0.81; P=0.75), urinary tract infection (OR: 1.57; P=0.28), renal colic (OR: 1.94; P=0.50), ureteral perforation (OR: 1.44; P=0.46), ureteral avulsion (OR: 1.21; P=0.83), stone migration (OR: 0.92; P=0.86) and sepsis (OR: 0.46; P=0.38) were observed between salvage URS and primary URS group.
DISCUSSION
The success rates and complications of URS were not impacted by previous unsuccessful SWL. The salvage URS is equally effective and safe to primary URS.

Meta-Analysis Review
Right hemicolectomy with complete mesocolic excision is safe, leads to an increased lymph node yield and to increased survival: results of a systematic review and meta-analysis.
BACKGROUND
The introduction of complete mesocolic excision (CME) for right colon cancer has raised an important discussion in relation to the extent of colic and mesenteric resection, and the impact this may have on lymph node yield. As uncertainty remains regarding the usefulness of and indications for right hemicolectomy with CME and the benefits of CME compared with a traditional approach, the purpose of this meta-analysis is to compare the two procedures in terms of safety, lymph node yield and oncological outcome.
METHODS
We performed a systematic review of the literature from 2009 up to March 15th, 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two hundred eighty-one publications were evaluated, and 17 met the inclusion criteria and were included. Primary endpoints analysed were anastomotic leak rate, blood loss, number of harvested lymph nodes, 3- and 5-year oncologic outcomes. Secondary outcomes were operating time, conversion, intraoperative complications, reoperation rate, overall and Clavien-Dindo grade 3-4 postoperative complications.
RESULTS
In terms of safety, right hemicolectomy with CME is not inferior to the standard procedure when comparing rates of anastomotic leak (RR 0.82, 95% CI 0.38-1.79), blood loss (MD -32.48, 95% CI -98.54 to -33.58), overall postoperative complications (RR 0.82, 95% CI 0.67-1.00), Clavien-Dindo grade III-IV postoperative complications (RR 1.36, 95% CI 0.82-2.28) and reoperation rate (RR 0.65, 95% CI 0.26-1.75). Traditional surgery is associated with a shorter operating time (MD 16.43, 95% CI 4.27-28.60) and lower conversion from laparoscopic to open approach (RR 1.72, 95% CI 1.00-2.96). In terms of oncologic outcomes, right hemicolectomy with CME leads to a higher lymph node yield than traditional surgery (MD 7.05, 95% CI 4.06-10.04). Results of statistical analysis comparing 3-year overall survival and 5-year disease-free survival were better in the CME group, RR 0.42, 95% CI 0.27-0.66 and RR 0.36, 95% CI 0.17-0.56, respectively.
CONCLUSIONS
Right hemicolectomy with CME is not inferior to traditional surgery in terms of safety and has a greater lymph node yield when compared with traditional surgery. Moreover, right-sided CME is associated with better overall and disease-free survival.

Meta-Analysis Review
Biliary hyperkinesia is typically diagnosed in patients with biliary-like pain and no evidence of gall stones on imaging modalities but who have had biliary scintigraphy scan (HIDA) that shows ejection fraction ≥ 80%. This study aims to identify whether the removal of the gall bladder can alleviate the symptoms associated with biliary hyperkinesia. Systematic search following PRISMA guidelines was done from inception to January 2020 using PubMed/Medline, OVID, Embase, Cochrane database of systemic reviews, Cochrane central register of controlled trials, The Database of Abstracts of Reviews of Effects (DARE) and Cochrane library databases. Results were expressed as risk ratios (RR) for dichotomous outcomes together with 95% confidence intervals (CI) or mean differences (MD) or standardized MD (SMD) for continuous outcomes. A meta-analysis was done using random-effect model in RevMan 5.4 software. Thirteen studies met the inclusion criteria and were included in the review. A total of 332 patients diagnosed with biliary hyperkinesia underwent cholecystectomy, of whom 303 (91.3%) reported symptomatic improvement RR 8.67 (95% CI 4.95, 15.16) P = 0.01. Six studies described abnormal histological features in 163/181 (90.05%) with high GB EF. RR 7.88 (95% CI 3.94, 15.75) P = 0.08. Chronic cholecystitis n = 155 (95%), cholesterolosis n = 7 (4.3%), and one showed features of acute cholecystitis. Patients with typical biliary colic symptoms without gallstones and markedly high ejection fraction might benefit from having cholecystectomy to alleviate their symptoms.

Review
Tobacco smoking in pregnancy is a worldwide public health problem. A majority of pregnant smokers need assistance to stop smoking. Most scientific societies recommend nicotine replacement therapy (NRT) during pregnancy but this recommendation remains controversial because of the known fetal toxicity of nicotine. The objective of this systematic review was to provide an overview of human studies about child health outcomes associated with NRT use during pregnancy. The electronic databases MEDLINE, the Cochrane Database, Web of Science, and ClinicalTrials.gov were searched from the inception of each database until 26 December 2020. A total of 103 articles were identified through database searching using combination of keywords. Out of 75 screened articles and after removal of duplicates, ten full-text articles were assessed for eligibility and five were included in the qualitative synthesis. NRT prescription seems to be associated with higher risk of infantile colic at 6 months as in case of smoking during pregnancy, and with risk of attention-deficit/hyperactivity disorder. No association between NRT during pregnancy and other infant health disorders or major congenital anomalies has been reported. Well-designed controlled clinical trials with sufficient follows-up are needed to provide more information on the use of NRT or other pharmacotherapies for smoking cessation during pregnancy on post-natal child health outcomes.
