Meta-Analysis
BACKGROUND
Omentoplasty is commonly used in various surgeries. However, its effectiveness is unsure due to lack of convincing data and research. To clarify the impact of omentoplasty on postoperative complications of various procedures, this systematic review and meta-analysis was performed.
METHODS
A systematic review of published literatures from four databases: PubMed, Web of Science, Cochrane Library, and Embase before 14 July 2022. The authors primarily included publications on five major surgical operations performed in conjunction with omentoplasty: thoracic surgery, esophageal surgery, gastrointestinal surgery, pelvi-perineal surgery, and liver surgery. The protocol was registered in PROSPERO.
RESULTS
This review included 25 273 patients from 91 studies ( n =9670 underwent omentoplasty). Omentoplasty was associated with a lower risk of overall complications particularly in gastrointestinal [relative risk (RR) 0.53; 95% CI: 0.39-0.72] and liver surgery (RR 0.54; 95% CI: 0.39-0.74). Omentoplasty reduced the risk of postoperative infection in thoracic (RR 0.38; 95% CI: 0.18-0.78) and liver surgery (RR 0.39; 95% CI: 0.29-0.52). In patients undergoing esophageal (RR 0.89; 95% CI: 0.80-0.99) and gastrointestinal (RR 0.28; 95% CI: 0.23-0.34) surgery with a BMI greater than 25, omentoplasty is significantly associated with a reduced risk of overall complications compared to patients with normal BMI. No significant differences were found in pelvi-perineal surgery, except infection in patients whose BMI ranged from 25 kg/m 2 to 29.9 kg/m 2 (RR 1.25; 95% CI: 1.04-1.50) and anastomotic leakage in patients aged over 60 (RR 0.59; 95% CI: 0.39-0.91).
CONCLUSION
Omentoplasty can effectively prevent postoperative infection. It is associated with a lower incidence of multiple postoperative complications in gastrointestinal and liver surgery.

INTRODUCTION
Peritoneal dialysis (PD)-associated peritonitis due to tuberculosis (TB) is associated with poor outcomes and optimal treatment strategies for this condition remain unknown. Our study aimed to: (i) systematically review the published literature on peritonitis caused by in patients on PD and (ii) review cases of peritonitis due to in patients on PD reported in Australia and New Zealand to determine the epidemiology, management strategies, and outcomes of this condition.
METHODS
A literature search of Medline, Scopus, Embase, ClinicalTrials.gov, Cochrane CENTRAL Register of Controlled Trials and Google Scholar for articles published from inception date to June 2022 was conducted. To be eligible, articles had to describe patient characteristics, initial anti-TB therapy, and treatment outcomes in all patients on PD with peritonitis caused by . Data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry of patients on PD who developed peritonitis due to between September 2001 and December 2020 were included and analyzed.
RESULTS
The systematic literature review identified 70 case studies (151 patients) and 8 cohort studies (97 patients), whereas the ANZDATA Registry identified 17 cases of peritonitis due to . Overall, in patients diagnosed with peritonitis due to , the rates of PD catheter removal and permanent transfer to hemodialysis (HD) were numerically higher in the ANZDATA Registry cases (82%) than in the case studies (23%) and cohort studies (20%). Observed all-cause mortality rates were also higher as observed in the case studies (33%) and cohort studies (26%) than in the ANZDATA Registry cases (6%).
CONCLUSION
Tuberculous peritonitis is uncommon in patients on PD and is associated with poor outcomes. Prospective studies are warranted to study the effect of retaining PD catheters after infection on patient outcomes.

Review
Dialysis in pediatric groups is complicated by a wide range of factors that can affect long-term prognosis. The purpose of this meta-analysis and systematic review is to better understand the demographic and clinical factors that affect dialysis success in children. We searched a variety of databases for relevant articles and included 14 reports that dealt with the case studies of pediatric patients undergoing dialysis for a wide range of renal diseases. Patients' demographics, clinical presentations, laboratory findings, and treatment outcomes were the primary areas of data collection. To get a better sense of the overall prevalence of certain outcomes and to spot noteworthy trends or patterns in the disease process, we conducted a meta-analysis. Variations in dialysis efficacy and outcomes are highlighted throughout a wide range of ages in the pediatric dialysis cohort, from neonates to teenagers. Acute kidney injuries (AKI) tended to impact more boys, but chronic kidney diseases (CKD), such as lupus nephritis, disproportionately afflicted girls. Many different ethnic groups were represented, and there was evidence that some diseases having a hereditary component were more common in some areas than others. However, the potential for long-term consequences remained a concern. Hemodialysis was found to be effective in controlling end-stage renal disease (ESRD) and AKI, with some patients going on to have a kidney transplant. At the same time, peritoneal dialysis was associated with an increased risk of infection. This comprehensive analysis highlights the importance of demographic and clinical parameters in determining pediatric dialysis outcomes. A 14.47% mortality rate and gender disparities are revealed by this meta-analysis of pediatric renal diseases, which included a cohort of 235 patients with conditions like lupus nephritis and hepatitis C infection. The findings stress the necessity for individualized treatment techniques and suggest that demographic characteristics should be addressed in prognostic models. For better patient outcomes, the study also suggests standardized reporting in pediatric dialysis studies.

Review
Hereditary diffuse gastric cancer (HDGC) is an autosomal-dominant syndrome associated with early onset diffuse gastric cancer. Definitive treatment is prophylactic total gastrectomy (PTG) associated with significant morbidity. Studies published from January 2000 to December 2022 reporting clinical, histopathological or health-related quality of life outcomes in HDGC patients undergoing PTG were identified. The study quality was assessed by the "Newcastle-Ottawa scale". Of the 257 articles screened, 21 were selected. A total of 353 patients were examined in 15 studies that reported surgical outcomes. The median age was 42 years old. The median major complication and mortality rates were 19.2% and 0.3%, respectively. The most common complications were wound infection at 4.8% followed by anastomotic leak and pulmonary complications at 4.5% each. Following PTG, 88.6% of patients had early lesions amongst 414 patients. The mean/median number of signet ring cell carcinoma foci in the gastrectomy specimens was from 2 to 78. All cases were stage 1 with no lymph node involvement. There was a wide range of psychosocial effects following PTG closely related to the physical symptoms. It is imperative for patients to receive comprehensive preoperative counselling to make an informed decision and be followed up under the care of a multidisciplinary team.

Meta-Analysis
Dialysis is a replacement therapy for patients with End-Stage Renal Disease (ESRD). Patients on dialysis are at high risk of acquiring hepatitis C virus (HCV), which has become a leading cause of morbidity and mortality in this population. There is a wide range of prevalence of HCV in dialysis populations around the world. It is still unknown how prevalent HCV infection is among worldwide dialysis patients (including those undergoing hemodialysis and peritoneal dialysis). A review was conducted to estimate the global epidemiology of hepatitis C in dialysis patients. We searched PubMed, Excerpta Medica Database (Embase), Global Index Medicus and Web of Science until October 2022. A manual search of references from relevant articles was also conducted. Heterogeneity was evaluated by the χ2 test on Cochrane's Q statistic, and the sources of heterogeneity were investigated using subgroup analysis. In order to assess publication bias, funnel plots and Egger tests were conducted, and pooled HCV prevalence estimates were generated using a DerSimonian and Laird meta-analysis model. The study is registered with PROSPERO under CRD42022237789. We included 634 papers involving 392160 participants. The overall HCV case fatality rate was 38.7% (95% CI = 28.9-49). The global prevalence of HCV infection in dialysis population group were 24.3% [95% CI = 22.6-25.9]. As indicated by UNSD region, country, dialysis type, and HCV diagnostic targeted; Eastern Europe had the highest prevalence of 48.6% [95% CI = 35.2-62], Indonesia had 63.6% [95% CI = 42.9-82], hemodialysis patients had 25.5% [95% CI = 23.8-27.3], and anti-HCV were detected in 24.5% [95% CI = 22.8-26.2]. Dialysis patients, particularly those on hemodialysis, have a high prevalence and case fatality rate of HCV infection. Hemodialysis units need to implement strict infection control measures.

The influence of preoperative e intraoperative factors in predicting postoperative morbidity and mortality in perforated diverticulitis: a systematic review and meta-analysis.
To determine if preoperative-intraoperative factors such as age, comorbidities, American Society of Anesthesiologists (ASA) classification, body mass index (BMI), and severity of peritonitis affect the rate of morbidity and mortality in patients undergoing a primary anastomosis (PA) or Hartmann Procedure (HP) for perforated diverticulitis. This is a systematic review and meta-analysis, conducted according to PRISMA, with an electronic search of the PubMed, Medline, Cochrane Library, and Google Scholar databases. The search retrieved 614 studies, of which 11 were included. Preoperative-Intraoperative factors including age, ASA classification, BMI, severity of peritonitis, and comorbidities were collected. Primary endpoints were mortality and postoperative complications including sepsis, surgical site infection, wound dehiscence, hemorrhage, postoperative ileus, stoma complications, anastomotic leak, and stump leakage. 133,304 patients were included, of whom 126,504 (94.9%) underwent a HP and 6800 (5.1%) underwent a PA. There was no difference between the groups with regards to comorbidities (p = 0.32), BMI (p = 0.28), or severity of peritonitis (p = 0.09). There was no difference in mortality [RR 0.76 (0.44-1.33); p = 0.33]; [RR 0.66 (0.33-1.35); p = 0.25]. More non-surgical postoperative complications occurred in the HP group (p = 0.02). There was a significant association in the HP group between the severity of peritonitis and mortality (p = 0.01), and surgical site infection (p = 0.01). In patients with perforated diverticulitis, PA can be chosen. Age, comorbidities, and BMI do not influence postoperative outcomes. The severity of peritonitis should be taken into account as a predictor of postoperative morbidity and mortality.

Meta-Analysis
INTRODUCTION
Abdominal surgical emergencies remain prevalent in various healthcare settings, particularly in regions with limited access to basic surgical care, such as Africa. The aim of this literature review is to systematically assess publications on abdominal surgical emergencies in adults in sub-Saharan Africa to estimate their prevalence and mortality rate.
METHODOLOGY
A systematic review was conducted. The latest search was performed on October 31, 2022. We estimated the pooled prevalence with a 95% confidence interval (CI) for each abdominal surgical emergency, as well as overall postoperative mortality and morbidity rates.
RESULTS
A total of 78 studies were included, and 55.1% were single-center retrospective and monocentric studies. The mean age of the patients was 32.5 years, with a sex ratio of 1.94. The prevalence of each abdominal surgical emergency among all of them was as follows: appendicitis: 30.0% (95% CI: 26.1-33.9); bowel obstruction: 28.6% (95% CI: 25.3-31.8); peritonitis: 26.6% (95% CI: 22.2-30.9); strangulated hernias: 13,4% (95% CI: 10,3-16,5) and abdominal trauma: 9.4% (95% CI: 7.5-11.3). The prevalence of complications was as follows: mortality rate: 7.4% (95% CI: 6.0-8.8); overall postoperative morbidity: 24.2% (95% CI: 19.4-29.0); and surgical site infection 14.4% (95% CI: 10.86-18.06).
CONCLUSION
Our study revealed a high prevalence of postoperative complications associated with abdominal surgical emergencies in sub-Saharan Africa. More research and efforts should be made to improve access and quality of patient care.

BACKGROUND
Hepatorenal syndrome is a condition that occurs in people with chronic liver disease (such as alcoholic hepatitis, advanced cirrhosis, or fulminant liver failure) and portal hypertension. The prognosis is dismal, often with a survival of weeks to months. Hepatorenal syndrome is characterised by the development of intense splanchnic vasodilation favouring ascites and hypotension leading to renal vasoconstriction and acute renal failure. Therefore, treatment attempts focus on improving arterial pressure through the use of vasopressors, paracentesis, and increasing renal perfusion pressure. Several authors have reported that the placement of transjugular intrahepatic portosystemic shunts (TIPS) may be a therapeutic option because it decreases portal pressure and improves arterial and renal pressures. However, the evidence is not clearly documented and TIPS may cause adverse events. Accordingly, it is necessary to evaluate the evidence of the benefits and harms of TIPS to assess its value in people with hepatorenal syndrome.
OBJECTIVES
To evaluate the benefits and harms of transjugular intrahepatic portosystemic shunts (TIPS) in adults with hepatorenal syndrome compared with sham, no intervention, conventional treatment, or other treatments.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was 2 June 2023.
SELECTION CRITERIA
We included only randomised clinical trials with a parallel-group design, which compared the TIPS placement with sham, no intervention, conventional therapy, or other therapies, in adults aged 18 years or older, regardless of sex or ethnicity, diagnosed with chronic liver disease and hepatorenal syndrome. We excluded trials of adults with kidney failure due to causes not related to hepatorenal syndrome, and we also excluded data from quasi-randomised, cross-over, and observational study designs as we did not design a separate search for such studies.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were 1. all-cause mortality, 2. morbidity due to any cause, and 3. serious adverse events. Our secondary outcomes were 1. health-related quality of life, 2. non-serious adverse events, 3. participants who did not receive a liver transplant, 4. participants without improvement in kidney function, and 5. length of hospitalisation. We performed fixed-effect and random-effects meta-analyses using risk ratio (RR) or Peto odds ratio (Peto OR), with 95% confidence intervals (CI) for the dichotomous outcomes and mean difference (MD) or standardised mean difference (SMD) for the continuous outcomes. We used GRADE to assess certainty of evidence.
MAIN RESULTS
We included two randomised clinical trials comparing TIPS placement (64 participants) versus conventional treatment (paracentesis plus albumin 8 g/L of removed ascites) (66 participants). The co-interventions used in the trials were dietary treatment (sodium less than 60 mmoL/day), spironolactone (300 mg/day to 400 mg/day), and furosemide (120 mg/day). Follow-up was up to 24 months. Both were multicentre trials from Spain and the USA, and Germany, conducted between 1993 and 2002. Most participants were men (aged 18 to 75 years). We are uncertain about the effect of TIPS placement compared with conventional treatment, during the first 24 months of follow-up, on all-cause mortality (RR 0.88, 95% CI 0.55 to 1.38; 2 trials, 130 participants; I = 58%; very low-certainty evidence) and on the development of any serious adverse event (RR 1.60, 95% CI 0.10 to 24.59; 2 trials, 130 participants; I = 78%; very low-certainty evidence). The use of TIPS may or may not result in a decrease in overall morbidity such as bacterial peritonitis, encephalopathy, or refractory ascites, during the first 24 months of follow-up, compared with the conventional treatment (RR 0.95, 95% CI 0.77 to 1.18; 2 trials, 130 participants; I = 0%; low-certainty evidence). We are uncertain about the effect of TIPS placement versus conventional treatment on the number of people who did not receive a liver transplant (RR 1.03, 95% CI 0.93 to 1.14; 2 trials, 130 participants; I = 0%; very low-certainty evidence) or on the length of hospitalisation (MD -20.0 days, 95% CI -39.92 to -0.08; 1 trial, 60 participants; very low-certainty evidence). Kidney function may improve in participants with TIPS placement (RR 0.53, 95% CI 0.27 to 1.02; 1 trial, 70 participants; low-certainty evidence). No trials reported health-related quality of life, non-serious adverse events, or number of participants with improvement in liver function associated with the TIPS placement. Funding No trials reported sources of commercial funding or conflicts of interest between researchers. Ongoing studies We found one ongoing trial comparing TIPS with conventional therapy (terlipressin plus albumin) and listed one study as awaiting classification as no full-text article could be found.
AUTHORS' CONCLUSIONS
TIPS placement was compared with conventional treatment, with a follow-up of 24 months, in adults with hepatorenal syndrome type 2. Based on two trials with insufficient sample size and trial limitations, we assessed the overall certainty of evidence as low or very low. We are unsure if TIPS may decrease all-cause mortality, serious adverse events, the number of people who did not receive a liver transplant, and the days of hospitalisation because of the very low-certainty evidence. We are unsure if TIPS, compared with conventional treatment, has better effects on overall morbidity (bacterial peritonitis, encephalopathy, or refractory ascites). TIPS may improve kidney function, but the certainty of evidence is low. The trials included no data on health-related quality of life, non-serious adverse events, and liver function associated with the TIPS placement. We identified one ongoing trial and one study awaiting classification which may contribute to the review when information becomes available.

Meta-Analysis Review
Spontaneous bacterial peritonitis (SBP) is the most common infection in patients with cirrhosis and is associated with high mortality. Although recent literature reports mortality benefits to early diagnostic paracentesis, current guidelines do not offer specific recommendations for how quickly diagnostic paracentesis should be performed in patients with cirrhosis and ascites who are admitted to the hospital. Therefore, we conducted a systematic review and meta-analysis to evaluate outcomes among patients admitted to the hospital with cirrhosis and ascites receiving paracentesis within ≤ 12, ≤ 1 day, and > 1 day. Eight studies with 116,174 patients were included in the final meta-analysis. The pooled risk of in-hospital mortality was significantly lower in patients who underwent early (≤ 12 h or ≤ 1 day) compared to delayed (> 12 h or > 1 day) paracentesis (RR: 0.69, p < 0.00001), and in patients who underwent paracentesis compared to no paracentesis (RR: 0.74, p < 0.00001). On subgroup analysis, in-hospital mortality was significantly lower in both paracentesis within ≤ 12 h (RR: 0.61, p = 0.02) vs. > 12 h, and within ≤ 1 day (RR: 0.70, p < 0.00001) vs. > 1 day. While there was a trend towards decreased mortality in those undergoing paracentesis within ≤ 12 h compared to ≤ 1 day, the difference did not reach statistical significance. The length of hospital stay was significantly shorter by 5.38 days in patients who underwent early (≤ 12 h) compared to delayed (> 12 h) paracentesis (95% CI 4.24-6.52, p < 0.00001). Early paracentesis is associated with reduced mortality and length of hospital stay. We encourage providers to perform diagnostic paracentesis in a timely manner, at least within 1 day of hospital admission, for all patients with cirrhosis and ascites.

Meta-Analysis
BACKGROUND
Although laparoscopic lavage for perforated diverticulitis with peritonitis has been grabbing the headlines, it is known that the clinical presentation of peritonitis can also be caused by an underlying perforated carcinoma. The aim of this study was to determine the incidence of patients undergoing inadvertent laparoscopic lavage of perforated colon cancer as well as the delay in cancer diagnosis.
METHODS
The PubMed database was systematically searched to include all studies meeting inclusion criteria. Studies were screened through titles and abstracts with potentially eligible studies undergoing full-text screening. The primary endpoints of this meta-analysis were the rates of perforated colon cancer patients having undergone inadvertent laparoscopic lavage as well as the delay in cancer diagnosis. This was expressed in pooled rate % and 95% confidence intervals.
RESULTS
Eleven studies (three randomized, two prospective, six retrospective) totaling 642 patients met inclusion criteria. Eight studies reported how patients were screened for cancer and the number of patients who completed follow-up. The pooled cancer rate was 3.4% (0.9%, 5.8%) with low heterogeneity (Isquare2 = 34.02%) in eight studies. Cancer rates were 8.2% (0%, 3%) (Isquare2 = 58.2%) and 1.7% (0%, 4.5%) (Isquare2 = 0%) in prospective and retrospective studies, respectively. Randomized trials reported a cancer rate of 7.2% (3.1%, 11.2%) with low among-study heterogeneity (Isquare2 = 0%) and a median delay to diagnosis of 2 (1.5-5) months.
CONCLUSIONS
This systematic review found that 7% of patients undergoing laparoscopic lavage for peritonitis had perforated colon cancer with a delay to diagnosis of up to 5 months.
