Randomized Controlled Trial
IMPORTANCE
Peritoneal metastasis is the most frequent pattern of postoperative recurrence in patients with gastric cancer. Extensive intraoperative peritoneal lavage (EIPL) is a new prophylactic strategy for treatment of peritoneal metastasis of locally advanced gastric cancer; however, the safety and efficacy of EIPL is currently unknown.
OBJECTIVE
To evaluate short-term outcomes of patients with advanced gastric cancer who received combined surgery and EIPL or surgery alone.
DESIGN, SETTING, AND PARTICIPANTS
From March 2016 to November 2017, 662 patients with advanced gastric cancer receiving D2 gastrectomy were enrolled in a large, multicenter, randomized clinical trial from 11 centers across China. In total, 329 patients were randomly assigned to receive surgery alone, and 333 patients were randomly assigned to receive surgery plus EIPL. Clinical characteristics, operative findings, and postoperative short-term outcomes were compared between the 2 groups in the intent-to-treat population.
MAIN OUTCOMES AND MEASURES
Short-term postoperative complications and mortality.
RESULTS
The present analysis included data from 550 patients, 390 men and 160 women, with a mean (SD) age of 60.8 (10.7) years in the surgery alone group and 60.6 (10.8) in the surgery plus EIPL group. Patients assigned to the surgery plus EIPL group exhibited reduced mortality (0 of 279 patients) compared with those assigned to surgery alone (5 of 271 patients [1.9%]) (difference, 1.9%; 95% CI, 0.3%-3.4%; P = .02). A significant difference in the overall postoperative complication rate was observed between patients receiving surgery alone (46 patients [17.0%]) and those receiving surgery plus EIPL (31 patients [11.1%]) (difference, 5.9%; 95% CI, 0.1%-11.6%; P = .04). Postoperative pain occurred more often following surgery alone (48 patients [17.7%]) than following surgery plus EIPL (30 patients [10.8%]) (difference, 7.0%; 95% CI, 0.8%-13.1%; P = .02).
CONCLUSIONS AND RELEVANCE
Inclusion of EIPL can increase the safety of D2 gastrectomy and decrease postoperative short-term complications and wound pain. As a new, safe, and simple procedure, EIPL therapy is easily performed anywhere and does not require any special devices or techniques. Our study suggests that patients with advanced gastric cancer appear to be candidates for the EIPL approach.

BACKGROUND
Although peritoneal lavage with povidone-iodine (PVPI) is frequently performed after surgery on the gastrointestinal tract, the effects of PVPI on the intestinal epithelial barrier are unknown. The purpose of this study was to investigate the effects of abdominal irrigation with PVPI on the intestinal epithelial barrier in a colorectal cancer (CRC)-induced rat model.
MATERIALS AND METHODS
The CRC model was induced in rats with azoxymethane and dextran sodium sulfate. Next, a total of 24 male CRC-induced rats were randomly divided into three groups (n = 8): (1) a sham-operated group, (2) an NS group (peritoneal lavage 0.9% NaCl), and (3) a PVPI group (peritoneal lavage with 0.45%-0.55% PVPI). The mean arterial pressure was continuously monitored throughout the experiment. The levels of plasma endotoxin and D-lactate, blood gases, and protein concentration were measured. The ultrastructural changes of the epithelial tight junctions were observed by transmission electron microscopy.
RESULTS
The mean arterial pressure after peritoneal lavage was lower in the PVPI group than that in the NS group. The protein concentration and levels of endotoxin and D-lactate were higher in the PVPI group than they were in the PVPI group. In addition, PVPI treatment resulted in a markedly severe metabolic acidosis and intestinal mucosal injury compared with NS rats.
CONCLUSIONS
Peritoneal lavage with PVPI dramatically compromises the integrity of the intestinal mucosa barrier and causes endotoxin shock in CRC rats. It is unsafe for clinical applications to include peritoneal lavage with PVPI in colorectal operations.

Randomized Controlled Trial
OBJECTIVE
Laparoscopic surgery offers many advantages compared to invasive surgery but one of the main problems is postoperative pain, partially resulting from the peritoneal inflammatory process mediated by inflammatory cytokines. The rationale of this study is that intraperitoneal washing could remove inflammatory mediators that are the cause of postoperative pain and could help in the removal of CO2 from the abdominal cavity. This article aims to analyze the effects of peritoneal lavage in the reduction of postoperative shoulder pain.
PATIENTS AND METHODS
277 patients enrolled to undergo laparoscopic gynecologic surgery were included in the study. Women are randomized into two groups, according to the use or non-use of peritoneal lavage with saline solution at the end of laparoscopic gynecological major procedures.
RESULTS
Data show that the peritoneal lavage can significantly reduce postoperative pain in the first 36 hours after surgery, as well as patients' requests for analgesics: during the first 3 postoperative days, requests for paracetamol were lower in the YW (Yes Washing) group than the NW (No Washing) group (77 vs. 101; p<0.05); similar results are obtained considering ketorolac administration (62 vs. 71; p<0.05).
CONCLUSIONS
Peritoneal lavage after gynecological laparoscopic procedures may be effective in the reduction of postoperative pain and use of analgesics.

PURPOSE
In colorectal cancer, the role of detecting free malignant cells from peritoneal lavage is currently unclear. In this study, we investigated the positive rate of free malignant cells in peritoneal lavage fluid and their predictive value for prognosis and peritoneal recurrence after a curative resection.
METHODS
From October 2009 to December 2011, in a prospective manner, we performed cytologic examinations of peritoneal lavage fluid obtained just after the abdominal incision from 145 patients who underwent curative surgery for colorectal cancer. We used proportional hazard regression models to analyze the predictive role of positive cytology for peritoneal recurrence and survival.
RESULTS
Among total 145 patients, six patients (4.1%) showed positive cytology. During the median follow-up of 32 months (range, 8-49 months), 27 patients (18.6%) developed recurrence. Among them, 5 patients (3.4%) showed peritoneal carcinomatosis. In the multivariate analysis, positive cytology was an independent predictive factor for peritoneal recurrence (hazard ratio [HR], 136.5; 95% confidence interval [CI], 12.2-1,531.9; P < 0.0001) and an independent poor prognostic factor for overall survival (HR, 11.4; 95% CI, 1.8-72.0; P = 0.009) and for disease-free survival (HR, 11.1; 95% CI, 3.4-35.8; P < 0.0001).
CONCLUSION
Positive cytology of peritoneal fluid was significantly associated with peritoneal recurrence and worse survival in patients undergoing curative surgery for colorectal cancer. Peritoneal cytology might be a useful tool for selecting patients who need intraperitoneal or systemic chemotherapy.

BACKGROUND
Intra-abdominal adhesions are fibrous bands that develop after abdominal surgery or inflammation and cause mortality and morbidity following surgeries. This study aimed to assess the effects of bupivacaine, saline and two doses of lidocaine, after peritoneal lavage and to compare their effects in reducing abdominal adhesions in rat.
METHODS
In a blinded, randomised, placebo-controlled clinical trial, 50 female rats were anaesthetised and the parietal peritoneum was scratched to induce punctate bleeding. The rats were randomly assigned to five groups: saline, lidocaine 2% (3 and 6 mg/kg), bupivacaine 0.25% (2 mg/kg) and control (no irrigation). The peritoneal cavity was irrigated with the appropriate solution during laparotomy. Two weeks later, re-laparotomy was performed. The quantity, quality, severity and scores of adhesions were recorded and compared.
RESULTS
The quantity and quality of adhesions were significantly higher in the control group than in the lidocaine (6 mg/kg) and bupivacaine groups. The quality of the adhesions was higher in the normal saline group than in the lidocaine (6 mg/kg) and bupivacaine groups. The severity of adhesions between the lidocaine 3 and 6 mg/kg groups and between the lidocaine 3 mg/kg and saline groups was lower than that in the control group.
CONCLUSION
Using lidocaine (6 mg/kg) and bupivacaine lavage in first laparotomy reduces abdominal peritoneal obstruction because of the formation of adhesion bands.

Peritoneal adhesion represents a severe complication following surgery. Punica granatum (pomegranate) possesses several anti-oxidative and anti-inflammatory properties. Pomegranate peel extract (PPEx) can alleviate the production of various inflammatory factors and cytokines. Thus, we sought to evaluate the anti-adhesion effects of pomegranate in rats. Thirty male Wistar rats (6-week-old, 220 ± 20 g) were divided into five groups (n = 6): normal group without any surgical procedures, control group, and experimental groups receiving 2 ml of 1%, 2%, and 4% w/v PPEx, respectively. Peritoneal adhesions were examined macroscopically. Furthermore, we evaluated inflammatory cytokines levels [interleukin 6 (IL-6), and tumour necrosis factor-α (TNF-α)], growth factors [transforming growth factor- β1 (TGF-β1), and vascular endothelial growth factor (VEGF)], and oxidative stress parameters [nitric oxide metabolites (NO), and malondialdehyde (MDA), and glutathione (GSH)] using biochemical methods. Our results showed that the adhesion score and IL-6, TNF-α, TGF-β1, VEGF, NO, and MDA levels were increased in the control group. In contrast, the GSH level was diminished in the control group compared with the normal group (P < 0.001). PPEx (1 and 2% w/v) markedly reduced all measured parameters compared with the control group (P < 0.001-0.05). PPEx may reduce peritoneal adhesion by alleviating adhesion formation, IL-6, TNF-α, TGF-β1, VEGF, NO, and MDA, and stimulating anti-oxidative factors. Therefore, PPEx may be considered an appropriate candidate for the treatment of postoperative peritoneal adhesion.

Meta-Analysis Review
OBJECTIVES
The aims of this review were to determine whether positive peritoneal lavage cytology (CY+) precludes radical resection in pancreatic cancer and to propose prospections for future studies.
METHODS
MEDLINE, Embase, and Cochrane Central were searched for related articles. Dichotomous variables and survival outcomes were analyzed with the estimation of odds ratio and hazards ratio (HR), respectively.
RESULTS
A total of 4905 patients were included, of which 7.8% were CY+. Positive peritoneal lavage cytology was correlated with poor overall survival (univariate survival analysis [HR, 2.35; P < 0.00001]; multivariate analysis [HR, 1.62; P < 0.00001]), poor recurrence-free survival (univariate survival analysis [HR, 2.50; P < 0.00001]; multivariate analysis [HR, 1.84; P < 0.00001]), and higher initial peritoneal recurrence rate (odds ratio, 5.49; P < 0.00001).
CONCLUSIONS
Although CY+ predicts poor prognosis and a higher risk of peritoneal metastasis after curative resection, it is not sufficient to preclude curative resection based on the current evidence, and high-quality trials should be conducted to assess the prognostic impact of operation among resectable CY+ patients. In addition, more sensitive and accurate methods to detect peritoneal exfoliated tumor cells and more effective comprehensive treatment for resectable CY+ pancreatic cancer patients are clearly warranted.

Randomized Controlled Trial
BACKGROUND
Peritoneal lavage has been proposed to remove bacterial contamination and other materials promoting bacterial proliferation and pro-inflammatory cytokines that may enhance local inflammation. The aims of this study were to evaluate the effects of peritoneal lavage with physiologic saline or an antibiotic solution (clindamycin-gentamicin) on post-operative pain and analytic acute-phase reactants and to determine the microbiologic impact of both irrigations on peritoneal contamination in patients undergoing laparoscopic sleeve gastrectomy (LSG) as a bariatric procedure.
METHODS
The patients were randomized into two groups: Those undergoing an intra-abdominal lavage with physiologic saline (Group 1; n = 40) and those undergoing a similar lavage with a gentamicin-clindamycin solution (Group 2; n = 40). Peritoneal contamination, post-operative pain, and analytic acute-phase reactants 24 h after surgery were investigated.
RESULTS
The median pain score 24 h after surgery was 3.5 in Group 1 and 1.5 in Group 2 (p = 0.021). The glucose concentration (mean difference 33.1 mg/dL; p = 0.004), aspartate aminotransferase (AST) concentration (mean difference 41.8 U/L; p = 0.009), alanine aminotransferase (ALT) concentration (mean difference 34.2 U/L; p = 0.029), white blood cell count (mean difference 1930/mm(3); p = 0.029); C-reactive protein concentration (mean difference 27.3 mg/L; p = 0.036), and serum lactic acid concentration (mean difference 0.34 mg/L; p = 0.049) were significantly higher in Group 1. Peritoneal contamination also was significantly higher in Group 1 (17.5% vs 0; p = 0.006).
CONCLUSIONS
Intra-peritoneal irrigation with a gentamicin and clindamycin solution in patients undergoing LSG leads to a reduction in post-operative pain and peritoneal contamination, less alteration of acute-phase reactants, lower blood glucose concentration, a smaller increase in liver enzymes, and a shorter hospital stay.
