Review
BACKGROUND
Viral transmission to healthcare providers during surgical procedures was a major concern at the outset of the COVID-19 pandemic. The presence of the severe acute respiratory disease syndrome coronavirus (SARS-CoV-2), the virus responsible for COVID-19, in the abdominal cavity as well as in other abdominal tissues which surgeons are exposed has been investigated in several studies. The aim of the present systematic review was to analyze if the virus can be identify in the abdominal cavity.
METHODS
We performed a systematic review to identify relevant studies regarding the presence of SARS-CoV-2 in abdominal tissues or fluids. Number of patients included as well as patient's characteristics, type of procedures, samples and number of positive samples were analyzed.
RESULTS
A total of 36 studies were included (18 case series and 18 case reports). There were 357 samples for detection of SARS-CoV-2, obtained from 295 individuals. A total of 21 samples tested positive for SARS-CoV-2 (5.9%). Positive samples were more frequently encountered in patients with severe COVID-19 (37.5% vs 3.8%, p < 0.001). No health-care provider related infections were reported.
CONCLUSION
Although a rare occurrence, SARS-CoV-2 can be found in the abdominal tissues and fluids. It seems that the presence of the virus in the abdominal tissues or fluids is more likely in patients with severe disease. Protective measures should be employed in the operating room to protect the staff when operating patients with COVID-19.

Review
Postoperative pancreatic fluid collection (POPFC) is an important complication following abdominal surgery. POPFC causes significant morbidity and mortality. Management options are time-consuming and severely affect patient's quality of life. Surgical and/or percutaneous drainage (PCD) is the traditional mainstay of treatment. Studies have shown that EUS could have a role to play in the management of POPFC. Data are limited in the comparison of clinical outcomes with EUS as compared to PCD to this end. We conducted a comprehensive search of multiple electronic databases and conference proceedings including PubMed, EMBASE, Google Scholar, LILACS, and Web of Science databases (earliest inception through September 2018) to identify studies that reported on the clinical outcomes of EUS and PCD in the management of POPFC. The goals were to estimate and compare the pooled rates of technical success, clinical success, adverse events, and POPFC recurrence with EUS and PCD. A total of 13 studies were included in the analysis. Ten studies (239 patients) used EUS and 6 studies (267 patients) used PCD in the management of POPFC. The pooled rate of clinical success with EUS was 93.2% (95% confidence interval [CI] 88.2-96.2, I = 0) and with PCD was 79.8% (95% CI 70-87, I = 74). The difference was statistically significant, P = 0.002. Recurrence rate was significantly lower with EUS as compared to PCD (9.4%: 95% CI 5.2-16.5 vs. 25.7%: 95% CI 24.3-41.7; P = 0.02). Pooled rates of technical success and adverse events were similar with EUS and PCD. Our meta-analysis shows that EUS has significantly better clinical outcomes, in terms of clinical success and disease recurrence, in the management of POPFC as compared to PCD.

Meta-Analysis Review
BACKGROUND
Peri-operative fluid therapy is a controversial area with few randomised trials to guide practice. Recently, a number of trials have suggested that intra-operative therapy guided by oesophageal Doppler acquired haemodynamic variables may improve postoperative outcome.
METHODS
Abstract databases and conference proceedings were searched to identify randomised controlled trials comparing Doppler-guided intra-operative fluid management to standard practice in patients undergoing major abdominal surgery. Pooled odds ratios (POR) and weighted mean differences (WMD) were calculated for categorical and continuous outcomes respectively.
RESULTS
Four trials, comprising 393 patients, were identified. Use of an oesophageal Doppler-guided fluid management algorithm resulted in fewer postoperative complications (POR 0.32; 95% CI: 0.19-0.52; p < 0.0001) and shorter hospital stays (WMD 1.68 days; 95% CI: 2.39-0.98; p < 0.0001). There were no significant differences in the quantities of intra-operative fluids administered although there was some evidence of heterogeneity with respect to this outcome.
CONCLUSION
Oesophageal Doppler-guided fluid management may improve outcome following major intra-abdominal surgery. However, comparison with fluid restriction strategies, including a cost-effectiveness analysis are required.

BACKGROUND
Fluid management practices during and after liver transplantation vary widely among centers despite better understanding of the pathophysiology of end-stage liver disease and of the effects of commonly used fluids. This reflects a lack of high quality trials in this setting, but also provides a rationale for both systematic review of all relevant studies in liver recipients and evaluation of new evidence from closely related domains, including hepatology, non-transplant abdominal surgery, and critical care.
OBJECTIVES
To develop evidence-based recommendations for perioperative fluid management to optimize immediate and short-term outcomes following liver transplantation.
DATA SOURCES
Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central.
METHODS
Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. Studies included those evaluating the following postoperative outcomes: acute kidney injury, respiratory complications, operative blood loss/red cell units required, and intensive care length of stay. PROSPERO protocol ID: CRD42021241392 RESULTS: Following expert panel review, 18 of 1624 screened studies met eligibility criteria for inclusion in the final quantitative synthesis. These included six single center RCTs, 11 single center observational studies, and one observational study comparing centers with different fluid management techniques. Definitions of interventions and outcomes varied between studies. Recommendations are therefore based substantially on expert opinion and evidence from other clinical settings.
CONCLUSIONS
A moderately restrictive or "replacement only" fluid regime is recommended, especially during the dissection phase of the transplant procedure. Sustained hypervolemia, based on absence of fluid responsiveness, elevated filling pressures and/or echocardiographic findings, should be avoided (Quality of Evidence: Moderate | Grade of Recommendation: Weak for restrictive fluid regime. Strong for avoidance of hypervolemia). Mean Arterial Pressure (MAP) should be maintained at >60-65 mmHg in all cases (Quality of Evidence: Low | Grade of Recommendation: Strong). There is insufficient evidence in this population to support preferential use of any specific colloid or crystalloid for routine volume replacement. However, we recommend against the use of 130/.4 HES given the high incidence of AKI in this population.

Enhanced recovery after surgery (ERAS ) Society abdominal and thoracic surgery recommendations: A systematic review and comparison of guidelines for perioperative and pharmacotherapy core items.
INTRODUCTION
Worldwide, ERAS Society guidelines have ushered in a new era of perioperative care. The purpose of this systematic review is to compare published core elements and pharmacotherapy recommendations embedded within ERAS Society abdominal and thoracic surgery (ATS) guidelines. Determining whether a consensus exists for pharmacological core items would make future guideline preparation for similar surgeries more standardized and could improve patient care by reducing unnecessary protocol variations.
METHODS
From the ERAS Society website as of May 2023, 16 current ERAS published ATS guidelines were included in the analysis to determine consensus and differing statements regarding each ERAS perioperative and pharmacotherapy-related item. The aims were to (a) determine whether a consensus for each item could be derived, (b) identify gaps in ERAS protocol development, and (c) propose potential research directions for addressing the identified gaps in the literature.
RESULTS
Core items with consensus included: preoperative smoking and alcohol cessation; avoiding bowel reparation and fasting; multimodal preanesthetic, perioperative analgesia, and postoperative nausea and vomiting regimens; low molecular weight heparins for in-hospital and at-home venous thromboembolism prophylaxis; antibiotic prophylaxis; skin preparation; goal-directed perioperative fluid management with balanced crystalloids; perioperative nutrition care; ileus prevention with peripherally-acting mu receptor antagonists; and glucose control.
CONCLUSION
While consensus was found for aspects of 21 current ERAS guideline core items related to pharmacotherapy choice, details related to doses, regimen, timing of administration as well as unique aspects pertaining to specific surgeries remain to be researched and harmonized to promote guideline consistency and further optimize patient outcomes.

Meta-Analysis Review
A systematic review and individual patient data meta-analysis on intra-abdominal hypertension in critically ill patients: the wake-up project. World initiative on Abdominal Hypertension Epidemiology, a Unifying Project (WAKE-Up!).
Intra-abdominal hypertension (IAH), defined as a pathologically increase in intraabdominal pressure, is commonly found in critically ill patients. While IAH has been associated with several abdominal as well as extra-abdominal conditions, few studies have examined the occurrence of IAH in relation to mortality. The aim of this paper was to evaluate the prognostic role of IAH and its risk factors at admission in critically ill patients across a wide range of settings and countries. An individual patient meta-analysis of all available data and a systematic review of published (in full or as abstract) medical databases and studies between 1996 and June 2012 were performed. The search was limited to "clinical trials" and "randomized controlled trials", "adults", using the terms "intra-abdominal pressure", "intraabdominal hypertension" combined with any of the terms "outcome" and "mortality". All together data on 2707 patients, representing 21 centers from 11 countries was obtained. Data on 1038 patients were not analysed because of the following exclusion criteria: no IAP value on admission (N.=712), absence of information on ICU outcome (N.=195), age <18 or >95 years (N.=131). Data from 1669 individual patients (19 centers from 9 countries) were analyzed in the meta-analysis. Presence of IAH was defined as a sustained increase in IAP equal to or above 12 mmHg. At admission the mean overall IAP was 9.9±5.0 mmHg, with 463 patients (27.7%) presenting IAH with a mean IAP of 16.3±3.4 mmHg. The only independent predictors for IAH were SOFA score and fluid balance on the day of admission. Five hundred thirteen patients (30.8%) died in intensive care. The independent predictors for intensive care mortality were IAH, SAPS II score, SOFA score and admission category. This systematic review and individual patient data meta-analysis shows that IAH is frequently present in critically ill patients and it is an independent predictor for mortality.

Meta-Analysis Review
The aim is to assess the benefits and harms of routine abdominal drainage in laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until August 2016. We included all randomised clinical trials comparing drainage versus no drainage after laparoscopic cholecystectomy irrespective of language and publication status. We used standard methodological procedures in accordance with the PRISMA guidelines. A total of 2398 participants were randomised to drain (1197 participants) versus 'no drain' (1201 participants) in 16 trials included in this article. Pain 24 h after surgery was less severe in the no drain group (MD1.31; 95% CI, 0.96 to 1.65; p < 0.00001). Abdominal drainage prolonged operative time (MD 5.77 min; 95% CI 4.98 min-6.57 min; p < 0.00001) but not the length of hospital stay (MD 0.21 days; 95% CI -0.00 days to 0.42 days; p = 0.05). No significant difference was present with respect to the intra-abdominal fluid, wound infection, nausea or vomit, mortality after operation. There is no significant advantage of drain placement after laparoscopic cholecystectomy. Further well designed randomized clinical trials should be carefully re-considered.

Review
BACKGROUND
Abdominoscrotal hydrocele (ASH) is an uncommon condition characterized by a fluid-filled mass with inguinoscrotal and abdominal components. Controversy exists regarding the best management. We conducted a systematic review of the literature with special interest in presentation, management and outcomes.
METHODS
A search was conducted of the MEDLINE/PubMed, Embase, Ovid, Web of Science and Scopus databases. Two authors independently extracted data and assessed the risk of bias in each study.
RESULTS
We found 18 case series that met selection criteria, describing 116 patients with 146 hydroceles. Unilateral ASH was found in 59% of cases with almost even distribution between left and right-sided hydroceles. Ipsilateral undescended testicle, testicular dysmorphism, and contralateral pathology (inguinal hernia) often accompanied ASH. Management was always surgical. The most common approaches were inguinal (67.2%), combined laparoscopic + inguinal (11.2%), and scrotal (10.3%). Complications were poorly reported, but were generally minor. There were a decreased number of complications with the scrotal approach because of avoidance of a difficult inguinal dissection.
CONCLUSIONS
ASH is a rare entity treated most commonly via an inguinal approach. However, consideration should be given to combining with an extraperitoneal or laparoscopic approach given coexisting pathology, or to the scrotal approach for reducing morbidity.

Review
BACKGROUND
Gastrointestinal complications of COVID-19 have been reported over the last year. One such manifestation is bowel ischaemia. This study thus aims to provide a more holistic review of our current understanding of COVID-19-induced bowel ischaemia.
METHOD AND RESULTS
A meticulous search was performed using different keywords in PubMed and Google Scholar. Fifty-two articles were included in our study after applying inclusion and exclusion criteria and performing the qualitative assessment of the studies. A total of 25 702 patients were included in our study after the completion of the qualitative assessment.
DISCUSSION
The common symptoms of GIT in COVID-19 patients are as diarrhoea, vomiting, nausea and abdominal pain. The mechanism of bowel ischaemia is associated with the formation of emboli which is related to COVID-19's high affinity for angiotensin-converting enzyme-2 on enterocytes, affecting the superior mesenteric vessels. Clinically, patients present with abdominal pain and vomiting. CT angiography of the abdomen and pelvis showed acute intestinal ischaemia (mesenteric). Management is usually initiated with gastric decompression, fluid resuscitation, and haemodynamic support. Surgical intervention is also sought.
CONCLUSION
Intestinal ischaemia presenting in patients with COVID-19 has to be considered when symptoms of severe abdominal pain are present. More research and guidelines are required to triage patients with COVID-19 to suspect intestinal ischaemia and to help in diagnosis and management.

BACKGROUND
Abdominal cocoon or sclerosing encapsulating peritonitis is an uncommon condition in which the small bowel is completely or partially encased by a thick fibrotic membrane. Our study presents a case of sclerosing encapsulating peritonitis and conducts a literature review.
METHODS
A bibliographic research was conducted. Our research comprised 97 articles. Gender, age, symptoms, diagnostic procedures, and treatment were all included in the database of patient characteristics.
CASE PRESENTATION
A 51-year-old man complaining of a 2-day history of minor diffuse abdominal pain, loss of appetite, and constipation was presented in emergency department. Physical examination was indicative of intestinal obstruction. Laboratory tests were normal. Diffuse intraperitoneal fluid and dilated small intestinal loops were discovered on computed tomography (CT). An exploratory laparotomy was recommended, in which the sac membrane was removed and adhesiolysis was performed. He was discharged on the tenth postoperative day.
RESULTS
There were 240 cases of abdominal cocoon syndrome in total. In terms of gender, 151 of 240 (62.9%) were male and 89 of 240 (37%) were female. Ages between 20 and 40 are most affected. Symptoms include abdominal pain and obstruction signs. For the diagnosis of abdominal cocoon syndrome, CT may be the gold standard imaging method. The surgical operation was the treatment of choice in the vast majority of cases (96.7%). Only 69 of 239 patients (28.9%) were detected prior to surgery, and CT was applied in these cases.
CONCLUSION
Abdominal cocoon is a rare condition marked by recurrent episodes of intestinal obstruction. Surgical therapy is the most effective treatment option.
