Meta-Analysis Review
BACKGROUND
The aim of this meta-analysis and systematic review was to evaluate the association between intraoperative bile cultures and postoperative complications of patients undergoing pancreaticoduodenectomy.
METHODS
A detailed literature search was performed from January 2015 to July 2022 in PubMed, Web of Science, Google Scholar, and EMBASE for related research publications. The data were extracted, screened, and graded independently. An analysis of pooled data was performed, and a risk ratio with corresponding confidence intervals was calculated and summarized.
RESULTS
A total of 8 articles were included with 1,778 pancreaticoduodenectomy patients who had an intraoperative bile culture performed. A systematic review demonstrated that some of the most common organisms isolated in a positive intraoperative bile culture were Enterococcus species, Klebsiella species, and E. coli. Four studies also showed that specific microorganisms were associated with specific postoperative complications (surgical site infection and intra-abdominal abscess). The postoperative complications that were evaluated for an association with a positive intraoperative bile culture were surgical site infections (risk ratio = 2.33, 95% confidence interval [1.47-3.69], P < .01), delayed gastric emptying (risk ratio = 1.23, 95% confidence interval [0.63-2.38], P = n.s.), 90-day mortality (risk ratio = 0.68, 95% confidence interval [0.01-52.76], P = n.s.), postoperative pancreatic hemorrhage (risk ratio = 1.70, 95% confidence interval [0.33-8.74], P = n.s.), intra-abdominal abscess (risk ratio = 1.70, 95% confidence interval [0.38-7.56], P = n.s.), and postoperative pancreatic fistula (risk ratio = 0.97, 95% confidence interval [0.72-1.32], P = n.s.).
CONCLUSION
The cumulative data suggest that a positive intraoperative bile culture has no association with predicting the postoperative complications of delayed gastric emptying, 90-day mortality, postoperative pancreatic hemorrhage, intra-abdominal abscess, or postoperative pancreatic fistula. However, the data also suggest that a positive intraoperative bile culture was associated with a patient developing a surgical site infection.

Review
(1) Background: Although invasive fungal infections are a major cause of neonatal morbidity and mortality, data on the incidence and outcomes of localized abscesses in solid organs due to fungal infections are scarce. The aim of this study was to consolidate evidence and enhance our understanding on neonatal liver abscesses due to invasive fungal infections. (2) Methods: An electronic search of the PubMed and Scopus databases was conducted, considering studies that evaluated fungal liver abscesses in the neonatal population. Data on the epidemiology, clinical course, treatment, and outcome of these infections were integrated in our study. (3) Results: Overall, 10 studies were included presenting data on 19 cases of neonatal fungal liver abscesses. spp. were the most common causative pathogens (94.7%). Premature neonates constituted the majority of cases (93%), while umbilical venous catheter placement, broad spectrum antibiotics, and prolonged parenteral nutrition administration were identified as other common predisposing factors. Diagnosis was established primarily by abdominal ultrasonography. Medical therapy with antifungal agents was the mainstay of treatment, with Amphotericin B being the most common agent (47%). Abscess drainage was required in four cases (21%). Eradication of the infection was achieved in the majority of cases (80%). (4) Conclusions: Even though fungal liver abscess is a rare entity in the neonatal population, clinicians should keep it in mind in small, premature infants who fail to respond to conventional treatment for sepsis, particularly if an indwelling catheter is in situ. A high index of suspicion is necessary in order to achieve a timely diagnosis and the initiation of the appropriate treatment.

Review
This meta-analysis aims to evaluate the comparative outcomes of drain insertion versus no drain after appendicectomy for complicated appendicitis. A systematic search of PubMed, Cochrane Library and Scopus was conducted, and all studies comparing drain versus no drain after appendicectomy for complicated appendicitis were included. Abdominal collection, surgical site infection (SSI), bowel obstruction, faecal fistula, paralytic ileus, length of hospital stay (LOS) and mortality were the evaluated outcome parameters for the meta-analysis. Seventeen studies reporting a total number of 4,255 patients who underwent appendicectomy for complicated appendicitis with (n=1,580) or without (n=2,657) drain were included. There was no significant difference between the two groups regarding abdominal collection (odds ratio (OR)=1.41, P=0.13). No-drain group was superior to the drain group regarding SSI (OR=1.93, P=0.0001), faecal fistula (OR=4.76, P=0.03), intestinal obstruction (OR=2.40, P=0.04) and paralytic ileus (OR=2.07, P=0.01). There was a difference regarding mortality rate between the two groups (3.4% in the drain group vs 0.5% in the no-drain group, risk difference (RD)=0.01, 95% CI (-0.01, 0.04), P=0.36). In conclusion, this meta-analysis has shown that drains have no effect on the development of intra-abdominal collections in complicated appendicitis, but it can significantly increase the risk of postoperative complications such as fistula, surgical site infection (SSI), bowel obstruction, ileus and length of hospital stay.

Meta-Analysis Review
BACKGROUND
Liver abscesses differ in their aetiology, location, and number. Image-guided percutaneous drainage techniques are the currently used management for liver abscesses. We conducted our study to compare the clinical safety and efficacy of percutaneous needle aspiration (PNA) to percutaneous catheter drainage (PCD).
METHODS
A systematic review of major reference databases was undertaken in February 2022 for randomized controlled trials (RCTs) that compare PNA to PCD in treating liver abscess patients. The quality of the included trials was assessed using the Cochrane tool. Statistical meta-analysis was conducted using RevMan and open meta-analyst software.
RESULTS
Fifteen RCTs were included in this review, with 1676 patients enrolled. The overall quality of the included trials was moderate, with most domains of unclear risk. PCD was superior to PNA in the success rate (RR = 1.23; 95% CI [1.12, 1.36], P < 0.00001), time for achieving 50% reduction of cavity size (MD = -2.32; 95% CI [-3.07, -1.57], P < 0.00001), and time for clinical improvement (MD = -1.92; 95% CI [-2.55, -1.28], P < 0.00001). The two modalities did not differ in the days of hospital stay, duration of IV antibiotics, and time needed for total or subtotal reduction of cavity size (P = 0.36, P = 0.06 and P = 0.40, respectively). High heterogeneity levels were detected. Regarding major complications, the two modalities were equally safe (P = 0.39).
CONCLUSION
PCD has a higher success rate and results in a faster 50% reduction in the abscess cavity size and clinical improvement. The two modalities are equally safe.

Review
A systematic review was conducted in compliance with PRISMA statement standards to identify all studies reporting outcomes of laparoscopic resection of benign or malignant lesions located in caudate lobe of liver. Pooled outcome data were calculated using random-effects models. A total of 196 patients from 12 studies were included. Mean operative time, volume of intraoperative blood loss, and length of hospital stay were 225 minutes (95% confidence interval [CI], 181-269 minutes), 134 mL (95% CI, 85-184 mL), and 7 days (95% CI, 5-9 days), respectively. The pooled risk of need for intraoperative transfusion was 2% (95% CI, 0%-5%). It was 3% (95% CI, 1%-6%) for conversion to open surgery, 6% (95% CI, 0%-19%) for need for intra-abdominal drain, 1% (95% CI, 0%-3%) for postoperative mortality, 2% (95% CI, 0%-4%) for biliary leakage, 2% (95% CI, 0%-4%) for intra-abdominal abscess, 1% (95% CI, 0%-4%) for biliary stenosis, 1% (95% CI, 0%-3%) for postoperative bleeding, 1% (95% CI, 0%-4%) for pancreatic fistula, 2% (95% CI, 1%-5%) for pulmonary complications, 1% (95% CI, 0%-4%) for paralytic ileus, and 1% (95% CI, 0%-4%) for need for reoperation. Although the available evidence is limited, the findings of the current study might be utilized for hypothesis synthesis in future studies. They can be used to inform surgeons and patients about estimated risks of perioperative complications until a higher level of evidence is available.

Meta-Analysis
BACKGROUND AND OBJECTIVES
As an emerging minimally invasive technology, endoscopic ultrasound (EUS) has been reported to treat pelvic abscess instead of surgical or image-guided percutaneous drainage (PCD) under certain conditions. The aim of this study was to assess the efficacy and safety of EUS-guided drainage for patients with pelvic abscesses.
METHODS
We conducted a comprehensive literature search on PubMed, Embase, Cochrane Library, and Web of Science databases (inception-March 2022). The main outcomes were technical success, clinical success, and complications. Comprehensive meta-analysis software was used to calculate the pooled event rate.
RESULTS
Twelve studies containing 272 patients were included. These pelvic abscesses most frequently developed after abdominal and pelvic surgery (n = 180, 66.2%), inflammatory bowel disease (n = 32, 11.8%), and other inflammatory conditions. Respectively, the pooled technical and clinical success rate was 100% and 88.7% [95% confidence interval (CI): 83.8-92.2%, I = 1.0%, p < 0.001]. After excluding an individual study, the pooled rate of complications changed from 11.5% (95% CI: 7.4-17.4%, I = 38.8%, p < 0.001) to 8.2% (95% CI: 5.0-13.3%, I = 0, p < 0.001).
CONCLUSIONS
EUS-guided drainage of the pelvic abscess was feasible, effective, and safe. Further randomized-controlled studies with large-sample sizes were required in the future.

Meta-Analysis Review
OBJECTIVE
A meta-analysis of the relevant literature evaluated the feasibility, safety, and potential benefits of single-incision laparoscopic appendectomy (SILA) relative to those of conventional laparoscopic appendectomy (CLA).
METHODS
The major biomedical databases, including ClinicalTrials.gov, were searched up to January 2022 for relevant randomized controlled trials (RCTs). SILA and CLA were compared regarding patient body mass index, operative time, and perioperative complications. The Cochrane Handbook and RevMan 5.3 were used to judge trial quality and perform the meta-analysis, respectively.
RESULTS
The 17 included RCTs comprised 2068 patients, of whom 1039 and 1029 patients underwent SILA and CLA, respectively. The operative time for SILA was longer than that for CLA (MD = 8.35 min, 95% CI = 6.58 to 10.11, P < 0.00001), but the cosmetic results from SILA were superior (SMD = 0.81, 95% CI = 0.58 to 1.03, P < 0.00001). However, the incidence rates were similar in terms of patient body mass index; postoperative pain scores; and rates of abdominal abscess, conversion to open surgery, ileus, surgical site infection, and overall perioperative complications between the two groups.
CONCLUSION
SILA is a safe technique for acute appendicitis, and its cosmetic outcomes are superior to those of CLA.

Review
BACKGROUND
Ultrasound (US)- or computed tomography-guided drainage for abdominal abscess is currently the first-line options for drainage, but both options have disadvantages. Patients without adequate windows for drainage mostly undergo surgical drainage. However, surgical drainage is invasive and expensive. Endoscopic US (EUS)-guided drainage is a minimally invasive alternative for abdominal abscess, but there is less consensus on its efficacy, safety and complications. This meta-analysis aims to evaluate EUS-guided drainage for abdominal abscess.
MATERIALS AND METHODS
We retrieved relevant papers on EUS-guided drainage for abdominal abscess from the PubMed, Cochrane Library, Web of Science and EMBASE databases. Each paper was reviewed, and data were extracted. We used R software version 3.6.3 to perform the meta-analysis. Fixed effects models were used for merging data.
RESULTS
A total of 11 papers met the inclusion criteria, with a total sample population of 264 patients. The meta-analysis showed that the pooled clinical success rate was 90% (95% confidence interval [CI], 0.85-0.95), the technical success rate was 99% (95% CI, 0.97-1.00) and the recurrence rate was 1% (95% CI, 0.00-0.03). Three studies reported the complications, including perforation, bleeding and stent migration; none of the other eight studies reported complications. There were no significant differences between subgroups. There was no publication bias in either the clinical or the technical success rates.
CONCLUSIONS
This meta-analysis showed that EUS-guided drainage for abdominal abscess was effective and safe, with an excellent technical success rate. In addition, EUS-guided drainage could be used for abscesses with complex anatomy. Nevertheless, complications and stent type should be considered.

BACKGROUND
The efficacy of enteral immunonutrition (EIN) in patients undergoing gastrointestinal cancer surgery remains debatable. This meta-analysis aimed to investigate the effectiveness of EIN administration in patients undergoing surgery for gastrointestinal cancer.
METHODS
From January 2000 to January 2022, PubMed, EMBASE, Cochrane Library, and Web of Science were thoroughly searched for randomized controlled trials (RCTs) with EIN versus standard diet or no supplement in patients undergoing surgery for gastrointestinal cancer. Overall complications and infectious complications were the primary outcomes. The secondary results were non-infectious complications, mortality, length of hospital stay, and enteral nutrition-related complications.
RESULTS
Thirty-five studies reporting 3,692 patients undergoing surgery for gastrointestinal cancer (including gastric cancer, colorectal cancer, esophageal cancer, periampullary cancer, or pancreatic cancer) were included. Compared with the control group, EIN group had a significantly decreased incidence of overall complications (RR = 0.79, < 0.001). Infectious complications in patients who received EIN were considerably lower than in the control group (RR = 0.66, < 0.001). Compared to the control group, the incidence of surgical site infection, abdominal abscess, anastomotic leakage, bacteremia, duration of systemic inflammatory response syndrome (SIRS), and duration of antibiotic therapy was significantly lower in the specific infectious complications treated with EIN. Still, there was no significant difference between the two groups with other infectious complications. Moreover, a substantial shortening in the length of hospital stay was shown in EIN group compared with the control group. Still, no significant effect of EIN was demonstrated in non-infectious complicatios and mortality. The enteral nutrition-related complications had no significant difference between two groups.
CONCLUSIONS
EIN is safe and effective in reducing overall complications, infectious complications, and hospital stay in patients undergoing gastrointestinal cancer surgery (including gastric cancer, colorectal cancer, esophageal cancer, periampullary cancer, or pancreatic cancer).

Review
This systematic review intends to evaluate incidence and symptoms of post-bariatric splenic complications as well as best available modalities establishing the diagnosis and management protocols. A systematic literature search was performed in electronic database until March 2022. A total of 41 articles were included on the subject of splenic complications following bariatric/metabolic surgery (BMS). Splenic abscess was the most common splenic complications (44.2%) after BMS and leak was the most common reported etiology of the splenic abscess. Fever and abdominal pain were the most common presenting symptom in all splenic complications and CT scan was the most common diagnostic modality. Splenic complications after BMS are relatively rare but may lead to dangerous consequences. Prompt diagnosis and treatment can prevent potentially life-threatening outcomes.
