Evaluation of mesh closure of laparotomy and extraction incisions in open and laparoscopic colorectal surgery : a systematic review and meta-analysisBackground and Objectives: Evisceration and incisional hernia (IH) represent a significant morbidity following open or laparoscopic colorectal surgery where midline laparotomy or extraction incision (EI) are performed. We executed a systematic review to evaluate primary mesh closure of laparotomy or EI in colorectal resections of benign or malignant conditions. Methods: A comprehensive literature search was performed using PubMed, Science Direct, Cochrane, and Google Scholar databases for studies comparing prophylactic mesh to traditional suture techniques in closing laparotomy in open approach or EI when minimally invasive surgery was adopted in colorectal procedures, regardless of the diagnosis. Both IH and evisceration were identified as primary outcomes. Secondary outcomes included surgical site infections (SSI), postoperative seroma, and length of hospital stay (LOS). Results: Six studies were included in our analysis with a total population of 1398 patients, of whom 411 patients had prophylactic mesh augmentation when closing laparotomy or EI, and 987 underwent suture closure. The mesh closure group had a significantly lower risk of developing IH compared to the conventional closure group (OR 0.23, p = 0.00001). This result was significantly consistent in subgroup analysis of open laparotomy or EI of laparoscopic surgery subgroups. There was no statistically notable difference in evisceration incidence (OR 0.51, p = 0.25). Secondary endpoints did not significantly differ between both groups in terms of SSI (OR 1.20, p = 0.54), postoperative seroma (OR 1.80, p = 0.13), and LOS (MD -0.54, p = 0.63). Conclusions: primary mesh reinforcement of laparotomy or EI closure in colorectal resections lessens IH occurrence. No safety concerns were identified; however, further high-quality research may provide more solid conclusions.

Ambulatory management of acute uncomplicated diverticulitis (AmbUDiv study) : a multicentre, propensity score matching studyIntroduction: Recent studies have suggested that ambulatory management is feasible for acute uncomplicated diverticulitis (AUD); however, there is still no consensus regarding the most appropriate management settings. This study presents a multi-centre experience of managing patients presenting with AUD, specifically focusing on clinical outcomes and comparing ambulatory treatment with in-patient management. Methods: A retrospective multi-centre study was conducted across four hospitals in the UK and included all adult patients with computed tomography (CT) confirmed (Hinchey grade 1a) acute diverticulitis over a 12-month period (January - December 2022). Patient medical records were followed up for 1-year post-index episode, and outcomes were compared between those treated through the ambulatory pathway versus inpatient treatment using 1:1 propensity score matching (PSM). All statistical analysis was performed using the R Foundation for Statistical Computing, version 4.4. Results: A total of 348 patients with Hinchey 1a acute diverticulitis were included (260 in-patients; 88 ambulatory pathway), of which nearly a third (31.3%) had a recurrent disease. Inpatient management was dominant (74.7%), with a median of 3 days of hospital stay. PSM resulted in 172 patients equally divided between the two care settings. Ambulatory management was associated with a lower readmission rate (P = 0.02 before PSM, P = 0.08 after PSM), comparable surgical (P = 0.57 before PSM, 0% in both groups after PSM) and radiological interventions (P = 0.99 before and after PSM) within one year. In both matched and non-matched groups, a strong association between readmissions and inpatient management was noted in univariate analysis (P = 0.03 before PSM, P = 0.04 after PSM) and multivariate analysis (P = 0.02 before PSM, P = 0.03 after PSM). Conclusion: Our study supports the safety and efficacy of managing patients with AUD through a well-designed ambulatory care pathway. In particular, hospital re-admission rates are lower and other outcomes are non-inferior to in-patient treatment. This has implications for substantial cost-savings and better utilisation of limited healthcare resources.

The risk and predictors of mortality in octogenarians undergoing emergency laparotomy: a multicentre retrospective cohort studyObjectives: This study aims to evaluate the risk of postoperative mortality in octogenarians undergoing emergency laparotomy. Methods: In compliance with STROCSS guideline for observational studies, we conducted a multicentre retrospective cohort study. All consecutive patients aged over 80 with acute abdominal pathology requiring emergency laparotomy between April 2014 and August 2019 were considered eligible for inclusion. The primary outcome measure was 30-day postoperative mortality, and the secondary outcome measures were in-hospital mortality and 1-year mortality. Statistical analyses included simple descriptive statistics, binary logistic regression analyses, and Kaplan-Meier survival statistics. Results: A total of 523 octogenarians were eligible for inclusion. Emergency laparotomy in octogenarians was associated with 21.8% (95% CI 18.3-25.6%) 30-day postoperative mortality, 22.6% (95% CI 19.0-26.4%) in-hospital mortality, and 40.2% (95% CI 35.9-44.5%) 1-year mortality. Binary logistic regression analysis identified ASA status (OR, 2.49; 95% CI 1.82-3.38, P < 0.0001) and peritoneal contamination (OR, 2.00; 95% CI 1.30-3.08, P = 0.002) as predictors of 30-day postoperative mortality. The ASA status (OR, 1.92; 95% CI 1.50-2.46, P < 0.0001), peritoneal contamination (OR, 1.57; 95% CI 1.07-2.48, P = 0.020), and presence of malignancy (OR, 2.06; 95% CI 1.36-3.10, P = 0.001) were predictors of 1-year mortality. Log-rank test showed significant difference in postoperative survival rates among patients with different ASA status (P < 0.0001) and between patients with and without peritoneal contamination (P = 0.0011). Conclusions: Emergency laparotomies in patients older than 80 years with ASA status more than 3 in the presence of peritoneal contamination carry a high risk of immediate postoperative and 1-year mortality. This should be taken into account in communications with patients and their relatives, consent process, and multidisciplinary decision-making process for operative or non-operative management of such patients.

A case of small bowel evisceration through the rectum and anusA 46-year-old man presented with a small bowel prolapsing through the anus after straining on the toilet, which was starting to become ischaemic. He admitted to inserting a plastic object in his rectum about half an hour before straining. The bowel was kept moist by placing an intravenous drip line with saline dripping onto a wet swab. In theatre, the bowel was found to be prolapsing through a hole in the upper rectum and out through the anus. It was reduced back into the abdominal cavity through the same perforation, which was 4 cm long, without needing to extend it. This was sutured with polydioxanone (PDS) 2-0 as there was no contamination with faeces or pus. Due to improvement in the appearance of a small bowel and an extremely bruised mesentery, a re-look was planned in 24 hours. At the re-look the small bowel appeared healthy, therefore no resection was performed. However, a loop colostomy was fashioned to protect the upper rectal perforation repair. This shows that resection is not always required in such cases.

Aggressive angiomyxoma of the ischioanal fossa in a post-menopausal woman.Aggressive angiomyxoma is a rare mesenchymal tumour, primarily arising in the soft tissue of the pelvis and perineum in women of reproductive age. There is a paucity of evidence on optimal management because of the rarity of these tumours, but the consensus has been for surgical excision. We present the case of a 65-year-old woman who was admitted with left-sided buttock pain and initially diagnosed with a perianal abscess. She underwent examination under anaesthesia rectum with surgical excision of the lesion, subsequent histopathological and immunochemical analysis was suggestive of aggressive angiomyxoma. To complement our case report, we also present a literature review focusing on aggressive angiomyxoma in the ischioanal fossa (also known as the ischiorectal fossa) with only eight cases of primary aggressive angiomyxoma involving the ischioanal fossa documented to date. The primary aims of this case report and literature review are to familiarise clinicians with the clinical, histopathological and immunochemical features of these tumours, and to increase appreciation that despite the rarity of aggressive angiomyxoma, it might be considered in the differential diagnosis of ischioanal lesions.

Impact of cumulative experience on the quality of screening colonoscopy: a 13-year observational study.Objective: To investigate trends in quality of screening colonoscopy (using the Global Rating Score) in the 13 years since introduction of the Bowel Cancer Screening Programme in England. Setting: An English Bowel Cancer Screening Programme colonoscopy service from 2007 to 2019. Methods: A retrospective observational study was undertaken using a prospectively collected database in order to analyse trends in screening endoscopies (including patients following positive faecal occult blood test or with high-risk findings on flexible sigmoidoscopy). The Global Rating Score quality indicators for Bowel Cancer Screening Programme colonoscopy were used as outcome measures, and trends over time were analysed. These included caecal intubation rate, adenoma detection rate, colorectal cancer detection rate, proportion of patients with minimal or mild discomfort scores, proportion of patients who required intravenous sedation, and adverse events. Results: There were 5352 colonoscopies included, performed by 3 endoscopists; 73.8% were index procedures (i.e. first Bowel Cancer Screening Programme colonoscopy) and the remainder were follow-up or surveillance colonoscopies. The mean age of patients was 66 (standard deviation 5) years, and 59.8% were male. Mean age increased over time (R2=0.033; p < 0.001). There were significant trends over time towards higher caecal intubation rate (p = 0.015), higher adenoma detection rate (p < 0.001), lower proportion requiring intravenous sedation (p < 0.001). There were no significant trends in comfort scores (p = 0.606), adverse events (p = 0.503) or colorectal cancer detection (p = 0.089). Conclusion: There was a consistent improvement in the Global Rating Score for Bowel Cancer Screening Programme colonoscopies since the start of the programme, even when quality was already high at the start. Patients can expect high-quality colonoscopy when participating in the Bowel Cancer Screening Programme.

Staged versus concomitant TAVI and PCI for the treatment of coexisting aortic stenosis and coronary artery diseaseAortic stenosis (AS) is one of the most common valvular pathologies. Severe coronary artery disease (CAD) often coexists with AS. Transcatheter aortic valve implantation (TAVI) and percutaneous coronary intervention (PCI) have been established as alternatives to open surgical interventions. The data on the timing for the treatment of the 2 conditions are scarce and depend on multiple factors. This review compares the clinical outcomes of the concomitant versus staged PCI and TAVI for the treatment of AS and CAD. A systematic, electronic search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines to identify relevant articles that compared outcomes of the staged versus concomitant approaches for the TAVI and PCI. Seven studies were included involving 3745 patients. We found no statistically significant difference in primary outcomes such as 30-day mortality [odds ratio (OR) = 0.78; 95% confidence interval (CI): 0.39-1.57] and secondary outcomes including length of hospital stay (mean difference = -4.74, 95% CI: -10.96 to 1.48), new-onset renal failure (OR = 0.83, 95% CI: 0.22-3.13), cerebrovascular accidents (OR = 1.28, 95% CI: 0.64-2.57), and intraoperative blood loss (OR = 0.83, 95% CI: 0.32-2.12). New pacemaker insertion was statistically significant in favor of the concomitant approach (OR = 0.78, 95% CI: 0.63-0.96). This analysis suggests that while the 2 approaches are largely comparable in terms of most outcomes, patients at risk of requiring a pacemaker postprocedure may benefit from a concomitant approach. In conclusion, concomitant TAVI + PCI approach is nonsuperior to the staged approach for the treatment of CAD and AS. This review calls for robust trials in the field to further strengthen the evidence.

Meta-analysis of randomised controlled trials comparing intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy: upgrading the level of evidence.The need for escalation of level of evidence regarding the comparative outcomes of intracorporeal (ICA) and extracorporeal (ECA) anastomosis in laparoscopic right hemicolectomy has been persistently highlighted by previous meta-analyses of level 2 and 3 evidence. A systematic search of electronic databases and bibliographic reference lists were conducted. Overall perioperative morbidity, anastomotic leak, surgical site infection (SSI), paralytic ileus, bleeding, postoperative pain within 5 days, length of incision, conversion to an open procedure, harvested lymph nodes, procedure time, and length of hospital stay were the evaluated outcome parameters. Four randomised controlled trials reporting a total of 399 patients evaluating outcomes of ICA (n = 199) and ECA (n = 200) in laparoscopic right hemicolectomy were included. The ICA was associated with significantly shorter length of incision (MD - 1.82, p < 0.00001), lower postoperative pain score on day 2 (MD - 0.69, p = 0.0007), day 3 (MD - 0.80, p = 0.02), day 4 (MD - 0.83, p = 0.01) and day 5 (MD - 0.49, p < 0.00001) when compared to ECA. Moreover, it was associated with significantly shorter length of hospital stay (MD - 0.27, p = 0.03). However, there was no significant difference in overall perioperative morbidity (RR 0.79, p = 0.47), anastomotic leak (RR 1.29, p = 0.65), SSI (RR 0.61, p = 0.42), bleeding (RR 0.70, p = 0.71), paralytic ileus (RR 0.60, p = 0.45), conversion to open (RD: - 0.02, p = 0.45), number of harvested lymph nodes (MD 0.82, p = 0.06), and procedure time (MD 16.04, p = 0.06) between two groups. The meta-analysis of level 1 evidence demonstrated that laparoscopic right hemicolectomy with ICA has comparable perioperative morbidity but better postoperative recovery than with ECA. The ICA is safe to be practiced more routinely where technical challenges allow.

Meta-analysis of laparoscopic mesh rectopexy versus posterior sutured rectopexy for management of complete rectal prolapse.Objectives: To evaluate comparative outcomes of laparoscopic mesh rectopexy (LMR) and laparoscopic posterior sutured rectopexy (LPSR) in patients with rectal prolapse. Methods: We conducted a systematic search of electronic databases and bibliographic reference lists with application of a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators, and limits. Recurrence, Cleveland Clinic Incontinence Score (CCIS), Cleveland Clinic Constipation Score (CCCS), surgical site infections, procedure time, and length of hospital stay were the evaluated outcome measures. Results: We identified 5 comparative studies reporting a total of 307 patients evaluating outcomes of LMR (n=160) or LPSR (n=147) in patients with rectal prolapse. LMR was associated with significantly lower recurrence rate (OR: 0.28, P=0.009) but longer procedure time (MD: 23.93, P<0.0001) compared to LPSR. However, there was no significant difference in CCIS (MD: -1.02, P=0.50), CCCS (MD: -1.54, P=0.47), surgical site infection (OR: 1.48, P=0.71), and length of hospital stay (MD: -1.54, P=0.47) between two groups. No mesh erosion was reported in any of the included studies at maximum follow-up point. Sub-group analyses with respect to ventral mesh rectopexy, posterior mesh rectopexy, randomised studies, and adult patients were consistent with the main analysis. Conclusions: LMR seems to be associated with lower recurrence but longer procedure time compared to LPSR. Although no mesh-related complications have been reported by the included studies, no definitive conclusions can be made considering that the included studies were inadequately powered for such outcome. Future high-quality randomised studies with adequate sample size are required.

Meta-analysis and trial sequential analysis of three-port vs four-port laparoscopic cholecystectomy (level 1 evidence)To compare the outcomes of three-port and four-port laparoscopic cholecystectomy. In compliance with PRISMA statement standards, electronic databases were searched to identify all comparative studies investigating outcomes of three-port vs four-port laparoscopic cholecystectomy. Two techniques were compared using direct comparison meta-analysis model. The risks of type 1 or type 2 error in the meta-analysis model were assessed using trial sequential analysis model. The certainty of evidence was assessed using GRADE system. Random effects modelling was applied to calculate pooled outcome data. Analysis of 2524 patients from 17 studies showed that both techniques were comparable in terms of operative time (MD:- 0.13, P = 0.88), conversion to open operation (OR:0.80, P = 0.43), gallbladder perforation (OR: 1.43, P = 0.13), bleeding from gallbladder bed (OR:0.81, P = 0.34), bile duct injury (RD: 0.00, P = 0.97), iatrogenic visceral injury (RD: - 0.00, P = 0.81), bile or stone spillage (OR:1.67, P = 0.08), port site infection (OR: 0.90, P = 0.76), port site hernia (RD: 0.00, P = 0.89), port site haematoma (RD: - 0.01, P = 0.23), port site seroma (RD: 0.00, P = 1.00), and need for reoperation (RD: - 0.00, P = 0.94). However, the three-port technique was associated with lower VAS pain score at 12 h (MD: - 0.66, P < 0.00001) and 24 h (MD: - 0.54, P < 0.00001) postoperatively, shorter length of hospital stay (MD:-0.09, P = 0.41), and shorter time to return to normal activities (MD: - 0.79, P = 0.02). Trial sequential analysis confirmed that the meta-analysis was conclusive with no significant risks of type 1 or type 2 error. Robust evidence (level 1 with high certainty) suggests that in an elective setting with uncomplicated cholelithiasis as indication for cholecystectomy, three-port laparoscopic cholecystectomy is comparable with the four-port technique in terms of procedural and morbidity outcomes and may be associated with less postoperative pain, shorter length of hospital stay and shorter time to return to normal activities.

A prospective study evaluating patient reported outcome measures in patients who have undergone chest wall perforator flapsAims: To evaluate Patient Reported Outcome Measures (PROMs) and surgical outcomes in patients undergoing Chest Wall Perforator Flaps (CWPFs). Methods: This was an observational single cohort study using an audit approach and a survey instrument. 84 patients who had undergone CWPFs in the last 5 years at the Department of Breast Surgery, City Hospital Birmingham, were identified from a pre-existing database. Surgical outcomes were recorded. Patients were contacted telephonically or in person at the time of follow-up and were asked to fill up a PROMs questionnaire. Results: Out of 84 patients, 58 patients chose to respond. The average age of the patients was 51.3 years (±8.2 years). The average follow-up was 15.4 months (±9.9 months). The most common histological subtype was Infiltrating ductal carcinoma (IDC)-Not otherwise specified 34/58 (58.6%). Majority of the patients had T2 cancers-28/58 (48.3%). 26/58 (44.8%) were node negative. Eight patients (13.7%) had post-operative complications. No patient had total/partial flap loss. Nine patients (15.5%) had margin re-excision. One patient developed distant metastasis while 1 patient developed a second primary. Fifty-one patients (88%) were either satisfied or very satisfied with the post-operative appearance of the breasts. Thirty-six patients (62%) had no/little persistent pain or tenderness post-surgery. Eighty-six per cent (38/44) of the patients undergoing Lateral Intercostal Artery Perforator (LICAP) Flap and 16/18 (89%) of patients undergoing Anterior Intercostal Artery Perforator (AICAP) flap had no/little difficulty in carrying out normal activities at follow up. Conclusion: CWPFs are associated with a low complication rate and a high patient satisfaction rate.

Comparison of staged repair versus single-stage complete repair for pulmonary atresia with ventricular septal defect: A systematic review and meta-analysis.Four comparative studies reporting a total of 264 patients who underwent SR (167 patients) or CR (97 patients) were included. Total mortality was higher in the SR group compared to the CR group (odds ratio (OR) 2.58, P = 0.03). Two groups were comparable regarding operative and early post-operative mortality (OR 1.37, P = 0.62), post-operative ventilation duration (mean difference (MD) - 1.58, P = 0.43), need for post-operative ECMO support rate (OR 4.72, P = 0.16), transcatheter re-intervention rate (OR 0.60, P = 0.53), unplanned re-operation rate (OR 0.73, P = 0.57), and LOS (MD - 3.39, P = 0.45). Higher rate of freedom from RVOT re-intervention was observed in the SR group (OR 4.16, P = 0.00001).

Should routine surgical wound drainage after ventral hernia repair be avoided? a systematic review and meta-analysisAims: To evaluate outcomes of drain use vs. no-drain use during ventral hernia repair. Methods: A PRISMA-compliant systematic review was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov and Science Direct. Studies comparing use of drains with no-drain during ventral hernia repair (primary or incisional) were included. Wound-related complications, operative time, need for mesh removal and early recurrence were the evaluated outcome parameters. Results: Eight studies reporting a total number of two thousand four hundred and sixty-eight patients (drain group = 1214; no-drain group = 1254) were included. The drain group had a significantly higher rate of surgical site infections (SSI) and longer operative time compared with the no-drain group [odds ratio (OR): 1.63, P = 0.01] and [mean difference (MD): 57.30, P = 0.007], respectively. Overall wound-related complications [OR: 0.95, P = 0.88], seroma formation [OR: 0.66, P = 0.24], haematoma occurrence [OR: 0.78, P = 0.61], mesh removal [OR: 1.32, P = 0.74] and early hernia recurrence [OR: 1.10, P = 0.94] did not differ significantly between the two groups. Conclusion: The available evidence does not seem to support the routine use of surgical drains during primary or incisional ventral hernia repairs. They are associated with increased rates of SSIs and longer total operative time with no significant advantage in terms of wound-related complications.

Transcatheter versus surgical closure of atrial septal defects: a systematic review and meta-analysis of clinical outcomes.Background: Atrial septal defects are a common form of CHD and dependent on the size and nature of atrial septal defects, closure may be warranted. The paper aims to compare outcomes of transcatheter versus surgical repair of atrial septal defects. Methods: A comprehensive electronic literature search was conducted. Primary studies were included if they compared both closure techniques. Primary outcomes included procedural success, mortality, and reintervention rate. Secondary outcomes included residual defect and mean hospital stay. Results: A total of 33 studies were included in meta-analysis. Mean total hospital stay was significantly shorter in the transcatheter cohort across both the adult (95% confidence interval, mean difference -4.05 (-4.78, -3.32) p < 0.00001) and paediatric populations (95% confidence interval, mean difference -4.78 (-5.97, -3.60) p < 0.00001). There were significantly fewer complications in the transcatheter group across both the adult (odds ratio 0.45, 95% confidence interval, [0.28, 0.72], p < 0.00001) and paediatric cohorts (odds ratio 0.26, 95% confidence interval, [0.14, 0.49], p < 0.00001). No significant difference in overall mortality was found between transcatheter versus surgical closure across the two groups, adult (odds ratio 0.76, 95% confidence interval, [0.40, 1.45], p = 0.41), paediatrics (odds ratio 0.62, 95% confidence interval, [0.21, 1.83], p = 0.39). Conclusion: Both transcatheter and surgical approaches are safe and effective techniques for atrial septal defect closure. Our study has demonstrated the benefits of transcatheter closure in terms of lower complication rates and mean hospital stay. However, surgery still has a place for more complex closure and, as we have demonstrated, shows no difference in mortality.

Outcomes following open versus laparoscopic multi-visceral resection for locally advanced colorectal cancer : a systematic review and meta-analysisBackground: This meta-analysis aims to compare morbidity, mortality, oncological safety, and survival outcomes after laparoscopic multi-visceral resection (MVR) of the locally advanced primary colorectal cancer (CRC) compared with open surgery. Materials and methods: A systematic search of multiple electronic data sources was conducted, and all studies comparing laparoscopic and open surgery in patients with locally advanced CRC undergoing MVR were selected. The primary endpoints were peri-operative morbidity and mortality. Secondary endpoints were R0 and R1 resection, local and distant disease recurrence, disease-free survival (DFS), and overall survival (OS) rates. RevMan 5.3 was used for data analysis. Results: Ten comparative observational studies reporting a total of 936 patients undergoing laparoscopic MVR (n = 452) and open surgery (n = 484) were identified. Primary outcome analysis demonstrated a significantly longer operative time in laparoscopic surgery compared with open operations (P = 0.008). However, intra-operative blood loss (P<0.00001) and wound infection (P = 0.05) favoured laparoscopy. Anastomotic leak rate (P = 0.91), intra-abdominal abscess formation (P = 0.40), and mortality rates (P = 0.87) were comparable between the two groups. Moreover the total number of harvested lymph nodes, R0/R1 resections, local/distant disease recurrence, DFS, and OS rates were also comparable between the groups. Conclusion: Although inherent limitations exist with observational studies, the available evidence demonstrates that laparoscopic MVR in locally advanced CRC seems to be a feasible and oncologically safe surgical option in carefully selected cohorts.

Sutures versus clips for skin closure following caesarean section: a systematic review, meta-analysis and trial sequential analysis of randomised controlled trials.Purpose: To evaluate comparative outcomes of skin closure with clips and sutures after caesarean section (CS). Methods: We conducted a systematic search of electronic information sources and bibliographic reference lists. Wound infection, wound separation, haematoma, seroma, re-admission, closure time, length of hospital stay, patient scar assessment scale (PSAS) and the observer scar assessment scale (OSAS) were the evaluated outcome parameters. Results: We identified 16 randomised controlled trials reporting a total of 4926 patients who had skin closure with sutures (n = 2724) or clips (n = 2202) following CS. Use of clips was associated with a significantly higher rate of wound separation (risk ratio (RR): 2.33, P = 0.004) and longer length of hospital stay (mean difference (MD): 1.21, P = 0.03) but shorter closure time (MD: 5.35, P = 0.00001) when compared to sutures group. There was no significant difference between the two groups in the risk of wound infection (RR: 1.12, P = 0.75), haematoma formation (RR: 2.46, P = 0.23), seroma (RR: 1.17, P = 0.73), re-admission rate (RR: 1.28, P = 0.73), PSAS (MD: 0.44, P = 0.73) and OSAS (MD: 0.32, P = 0.55). Trial sequential analysis showed the meta-analysis was conclusive for wound infection, wound separation and closure time; however, it was inconclusive for length of hospital stay, PSAS and OSAS due to risk of type 2 error. Conclusion: This meta-analysis of best available evidence (level 1) demonstrated that although skin closure with subcuticular sutures is more time-consuming than clips, it is associated with a significantly lower risk of wound separation and shorter length of hospital stay.

How effective are deep fixation and extraperitoneal approaches in preventing stoma complications: a meta-analysisPurpose/Background: Some surgical techniques, including prophy-lactic mesh placement and positioning stomas either through or lateral to rectus muscle, have been investigated for potential reduction of stoma complications. This systematic review evaluates efficacy and safety of two operative techniques: deep stomal fixation and extraperitoneal approach of stoma creation.
