Review
Incarcerated gravid uterus (IGU) is a serious complication of pregnancy that leads to adverse obstetric outcomes. The aim of this review was to describe this entity in detail. We also aimed to understand if pregnancies with predisposing risk factors that increase the risk of developing IGU had a difference in their clinical manifestations, treatment, and obstetric outcomes. The PubMed, MEDLINE, Embase, Scopus databases and clinicaltrials.gov were searched from inception to July 2023. Case reports and series that provided all the details of the pregnancy and IGU outcome were included. Study quality and risk of bias were assessed using a tool that is an adaptation from criteria listed by Pierson, Bradford Hills and Newcastle Ottawa scale modification. Patients with the condition of interest included in this review were grouped into those with documented, identified risk factors and no risk factors. The two groups were compared to understand the difference in obstetric outcome and presentation of IGU. Data were analyzed and summarized descriptively, categorical variables were assessed by chi-squared test or Fisher's exact test, and continuous variables by the Wilcoxon Mann Whitney test. Of 236 articles found, 62 articles with 80 cases were included in the final analysis. The median age was 32 [27-35] years. The median gestational age of diagnosis was 17 [14-26] weeks. The most common risk factor was fibroids (N = 22, 27.5 %). Most common presentation was urinary complaints and lower abdomen pain (N = 47, 58.6 %). Twenty-seven patients (33.6 %) needed more than one visit for the diagnosis to be made. Conservative management was the first step to treat IGU in most patients. Most common complication was fetal malpresentation (N = 13, 40.6 %). Patients with or without risk factors developing IGU had no statistical difference in- parity, median gestational age of diagnosis, delay in diagnosis, increased chance of misdiagnosis, management of IGU or in obstetric outcome (all p > 0.05). It is important to recognize this entity early to prevent obstetric complications especially when patients report urinary retention and abdomen pain. The presence of risk factors does not change the management course or obstetric outcome in patients with IGU. Hence it is reasonable to start with conservative management of IGU regardless of presence of risk factors or the gestational age of diagnosis, in clinical practice.

Meta-Analysis Review
Mass closure with a continuous suture using large bite stitching technique has been widely accepted for midline laparotomy wound closures. However, emerging evidence suggests the use of small bite technique to reduce rates of incisional ventral hernia, surgical site infection (SSI) and burst abdomen. This meta-analysis aims to compare small versus large bite stitching techniques to assess complication rates in midline laparotomy wound closures. A comprehensive multi-database search (OVID EBM Reviews, OVID Medline, EMBASE, Scopus) was conducted from database inception to 11th October 2021 according to PRISMA guidelines. We included studies comparing post-operative complication rates of small bite versus large bite stitching techniques for midline laparotomy wound closure. Extracted data was pooled for meta-analysis evaluating rates of incisional ventral hernia, SSI and burst abdomen. We included five randomized controlled trials (RCT) in the meta-analysis and three prospective cohort studies for qualitative analysis. A total of 1977 participants composed of 961 small bite and 1016 large bite technique patients were included from the five RCTs. There was a significant reduction in the rates of incisional ventral hernia and SSI with the small bite stitch technique with odds ratios (OR) of 0.39 (95% CI [0.21-0.71]) and 0.68 (95% CI [0.51-0.91]) respectively, and a trend in favour of reduced incidence of burst abdomen with OR of 0.60 (95% CI [0.15-2.48]). Small bite stitch technique in midline laparotomy wound closure may be superior over conventional mass closure using the large bite stitch technique, with statistically significant lower rates of incisional ventral hernia and SSI.

Meta-Analysis Review
PURPOSE
Complete mesocolic excision improves lymphadenectomy for right hemicolectomy and respects the embryological planes. However, its effect on cancer-free and overall survival is questioned. Therefore, we aimed to determine the potential benefits of the technique by performing a systematic review of the literature and meta-analysis of the available evidence.
METHODS
Web of Science, PubMed/Medline, and Embase were searched on February 22, 2023. Original studies on short- and long-term oncological outcomes of adult patients undergoing right hemicolectomy with complete mesocolic excision as a treatment for primary colon cancer were considered for inclusion. Outcomes were extracted and pooled using a model with random effects.
RESULTS
A total of 586 publications were identified through database searching, and 18 from citation searching. Exclusion of 552 articles left 24 articles for inclusion. Meta-analysis showed that complete mesocolic excision increased the lymph node harvest (5 studies, 1479 patients, MD 9.62, 95% CI 5.83-13.41, p > 0.0001, I 84%), 5-year overall survival (5 studies, 2381 patients, OR 1.88, 95% CI 1.14-3.09, p = 0.01, I 66%), 5-year disease-free survival (4 studies, 1376 patients, OR 2.21, 95% CI 1.51-3.23, p < 0.0001, I 0%) and decreased the incidence of local recurrence (4 studies, 818 patients, OR 0.27, 95% CI 0.09-0.79, p = 0.02, I 0%) when compared to standard right hemicolectomy. Perioperative morbidity was similar between the techniques (8 studies, 3899 patients, OR 1.04, 95% CI 0.89-1.22, p = 0.97, I 0%).
CONCLUSION
Meta-analysis of observational and randomised studies showed that right hemicolectomy with complete mesocolic excision for primary right colon cancer improves oncologic results without increasing morbidity/mortality. These results need to be confirmed by high-quality evidence and randomised trials in selected patients to assess who may benefit from the procedure.

Meta-Analysis
BACKGROUND
There is no consensus regarding hernia sac management during laparoscopic hernia repair, and this systematic review and meta-analysis aimed to compare the postoperative outcomes of sac reduction (RS) and sac transection (TS) during laparoscopic mesh hernia repair.
METHODS
We conducted a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) 2020 and AMSTAR 2 (Assessing the Methodological Quality of Systematic Reviews) guidelines. We used the RevMan 5.4 statistical package from the Cochrane collaboration for meta-analysis. A random effects model was used.
RESULTS
The literature search yielded six eligible studies including 2941 patients: 821 patients in the TS group and 2120 patients in the RS group. In the pooled analysis, the TS group was associated with a lower incidence of seroma (OR = 1.71; 95% CI [1.22, 2.39], p = 0.002) and shorter hospital stay (MD = -0.07; 95% CI [-0.12, -0.02], p = 0.008). There was no significant difference between the two groups in terms of morbidity (OR = 0.87; 95% CI [0.34, 2.19], p = 0.76), operative time (MD = -4.39; 95% CI [-13.62, 4.84], p = 0.35), recurrence (OR = 2.70; 95% CI [0.50, 14.50], p = 0.25), and Postoperative pain.
CONCLUSIONS
This meta-analysis showed that hernia sac transection is associated with a lower seroma rate and shorter hospital stay with similar morbidity, operative time, recurrence, and postoperative pain compared to the reduction of the hernia sac.

AIM
Haemophilic pseudotumours are complications in patients with haemophilia A or B and result from locally repetitive bleeding, mainly in the musculoskeletal system. Abdominal haemophilic pseudotumours are exceptionally rare but may cause severe complications. This systematic review aimed to evaluate therapy strategies for symptomatic abdominal haemophilic pseudotumours.
METHODS
We systematically searched three databases (Medline [PubMed], Web of Science and EMBASE) for publications published between 1995 and 2023. Two reviewers independently selected the studies, extracted data and performed a quality assessment using the JBI critical appraisal checklist.
RESULTS
From a total of 1199 articles, 39 articles describing 41 cases were included for final analysis. Conservative or interventional treatment was performed in 12 cases. In eight cases, a step-up to surgical therapy after interventional treatment was indicated. Primary surgical therapy was performed in 21 cases. Failure to cure was documented in 50% (n = 6) of patients treated in the first group, with a mortality rate of 16.6% (n = 2). Interventional therapy with a step-up to surgery showed no morbidity or mortality. Primary surgical resection documented favourable results in 66.6% (n = 14), with failure to cure in 9.5% (n = 2) and a mortality rate of 14.3% (n = 3).
CONCLUSION
Primary surgical resection can be a first-line therapy for symptomatic, abdominal haemophilic pseudotumours, whereas preoperative embolisation could be used as a bridging therapy before surgery, especially in emergency settings. Diagnostic biopsy and percutaneous drainage should be avoided to prevent complications.

Meta-Analysis Review
INTRODUCTION
Approximately one third of patients with Acute Type A Aortic Dissection (ATAAD) present with pre-operative malperfusion syndromes (MPS). Of these, mesenteric malperfusion represents the greatest risk to patients with respect to increased short-term mortality. In select patients, it may be feasible to offer a staged approach by treating the mesenteric malperfusion first, optimizing the patient in the intensive care setting and then, following with a central aortic repair. The aim of this systematic review is to summarize cohort studies assessing the role of pre-operative interventions for mesenteric malperfusion.
METHODS
An electronic literature search of five databases was performed to identify all relevant studies providing studies examining short-term mortality on patients who underwent either endovascular or open revascularisation of mesenteric ischemia prior to central aortic repair. The primary outcome was all-cause, short-term mortality. Secondary outcomes were comparative mortality between a delayed repair vs. aortic repair first strategy, rates of postoperative laparotomy, bowel resection, and mortality following delayed aortic repair.
RESULTS
The search strategy identified 8 studies qualifying for inclusion, with a total of 180 patients who underwent delayed aortic surgery in the setting of mesenteric MPS. The weighted short-term mortality following a mesenteric revascularisation first, delayed aortic surgery strategy was 22.5%. This strategy was also associated with a significantly lower mortality than a central repair first strategy (OR 0.07, 95% CI 0.02-0.27), and a significantly lower rate of postoperative laparotomy/bowel resection (OR 0.05, 95% CI 0.02-0.14). If patients survive to receive central repair, the weighted short-term mortality postoperatively is low (2.1%).
CONCLUSION
A summary of this evidence reveals a lower short-term mortality in hemodynamically stable patients with mesenteric malperfusion, along with a reduction in postoperative laparotomy/bowel resections. Of those patients who survive to receive central repair, short-term mortality remains very low in the select group of hemodynamically stable patients. Further high-quality studies with randomized or propensity matched data are required to verify these results.

BACKGROUND
Staging laparoscopy for gastric cancer is recommended to assess the tumor's locoregional extension and exclude peritoneal disease. As there is no consensus on optimizing the procedure's diagnostic accuracy, we aimed to systematically review the literature on operative techniques, followed by peritoneal lavage fluid assessment in gastric cancer patients. Specifically, we sought to indicate the most common characteristics of the procedure and cytological evaluation.
METHODS
This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol for this systematic review was registered on PROSPERO database (CRD: 42022306746). On September 2022, a search was carried out using Embase, Medline ALL, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection.
RESULTS
The search identified 1632 studies on staging laparoscopy and 2190 studies on peritoneal fluid assessment. Some 212 studies were included. Open Hasson was the method of choice in accessing the peritoneal cavity in 65% of the studies, followed by establishing a pneumoperitoneum at 10-12 mmHg in 52% of reports. Most frequently, the patient was positioned supine (70%), while a 30° scope and three ports were used to assess the peritoneal cavity clockwise (72%, 77%, and 85%, respectively). Right and left upper abdomen quadrants were the predominant area of laparoscopic exploration (both 65%), followed by the primary tumor region (54%), liver and pelvis (both 30%), and small bowel and spleen (19% and 17%, respectively). Regions of peritoneal lavage and aspiration were limited to the pelvis (50%), followed by right and left upper abdomen quadrants (37.5% and 50%, respectively). No studies compared different methods of operative techniques or analysis of ascites/fluid.
CONCLUSIONS
This study indicates a high heterogeneity in the technique of staging laparoscopy and peritoneal fluid assessment in gastric cancer patients. Further research and initiatives to reach a consensus on the standardization of the procedure are warranted.

Meta-Analysis
BACKGROUND
Sarcopenia refers to the progressive age- or pathology-associated loss of skeletal muscle. When measured radiologically as reduced muscle mass, sarcopenia has been shown to independently predict morbidity and mortality after elective abdominal surgery. However, the European Working Group on Sarcopenia in Older People (EWGSOP) recently updated their sarcopenia definition, emphasizing both low muscle 'strength' and 'mass'. The aim of this systematic review and meta-analysis was to determine the prognostic impact of this updated consensus definition of sarcopenia after elective abdominal surgery.
METHODS
MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched for studies comparing prognostic outcomes between sarcopenic versus non-sarcopenic adults after elective abdominal surgery from inception to 15 June 2022. The primary outcomes were postoperative morbidity and mortality. Sensitivity analyses adjusting for confounding patient factors were also performed. Methodological quality assessment of studies was performed independently by two authors using the QUality in Prognosis Studies (QUIPS) tool.
RESULTS
Twenty articles with 5421 patients (1059 sarcopenic and 4362 non-sarcopenic) were included. Sarcopenic patients were at significantly greater risk of incurring postoperative complications, despite adjusted multivariate analysis (adjusted OR 1.56, 95 per cent c.i. 1.39 to 1.76). Sarcopenic patients also had significantly higher rates of in-hospital (OR 7.62, 95 per cent c.i. 2.86 to 20.34), 30-day (OR 3.84, 95 per cent c.i. 1.27 to 11.64), and 90-day (OR 3.73, 95 per cent c.i. 1.19 to 11.70) mortality. Sarcopenia was an independent risk factor for poorer overall survival in multivariate Cox regression analysis (adjusted HR 1.28, 95 per cent c.i. 1.13 to 1.44).
CONCLUSION
Consensus-defined sarcopenia provides important prognostic information after elective abdominal surgery and can be appropriately measured in the preoperative setting. Development of targeted exercise-based interventions that minimize sarcopenia may improve outcomes for patients who are undergoing elective abdominal surgery.
