RESUMO

OBJECTIVE: Experimental assessment of the effect of modified and unmodified surgical suture material on abdominal adhesive process. MATERIAL AND METHODS: The study was performed on male rats of the Wistar subpopulation. There were 5 animals in each group. In all animals, midline abdominal incision was followed by suturing the parietal peritoneum with modified and unmodified suture material. All animals were euthanized with carbon dioxide vapors in 14 days after surgery. Macro- and microscopic assessment of severity of abdominal adhesive process was carried out. Two types of preparation of excised complexes 'peritoneum-suture material-adhesion' were applied for histological examination: paraffin sections and embedding in epoxy resin. Specimens were stained by Van Gieson and with methylene blue solution. Histological specimens were examined using Axio Imager A1 light microscope (Zeiss, Germany). RESULTS: Polypropylene filaments result extensive adhesions occupying about 75% of the area. Adhesions have a dense structure with signs of vascularization. Modification of suture material with solution of polyhydroxybutyrate/hydroxyvalerate and heparin reduce severity of adhesions. The use of modified suture material was followed by adhesions with more loose structure, no signs of vascularization. Adhesions occupied less than 25% of the area. Histological examination of excised complexes 'peritoneum-suture material-adhesion' revealed accumulation of inflammatory cells around the unmodified suture material, while there were no signs of tissue inflammatory process around the modified sutures. CONCLUSION: Application of polyhydroxybutyrate/hydroxyvalerate and heparin on the surface of surgical sutures is an effective method for prevention of abdominal adhesions.

RESUMO

Objective: We compared the extraperitoneal cesarean section to transperitoneal cesarean on fetal delivery time.Material and methods: This randomized study included 210 pregnant women undergoing cesarean section for elective reasons, repeat cesarean (< four), or dystocia. Patients who required an urgent cesarean section, who were at high risk for obstetric or maternal bleeding, who had a uterine or adnexal mass, or who requested tubal ligation were excluded from the study. The primary outcome of the study was the skin incision-to-delivery time. The sample size was set to detect of 1-minute difference in fetal delivery time between groups (two-tailed hypothesis, α = 0.05, ß = 0.10). Secondary outcome measures were total operation time, intraoperative nausea, gag reflex, vomiting, pain and anxiety for those receiving regional anesthesia, postoperative pain, change in hemoglobin, postoperative analgesic requirements, nausea, vomiting and shoulder pain, urogenital distress, time until gas passage, and neonatal outcome.Results: No significant difference occurred between the two groups for skin incision-to- delivery time (extraperitoneal cesarean 3.9 minutes [2.1-7.3] versus transperitoneal cesarean 4.2 minutes [1.9-8.2], p = .065). Significant differences regarding intraoperative pain, total operation time, postoperative pain at the surgical site and shoulder pain, analgesic requirements, time until gas passage, and oral tolerability favored the extraperitoneal group. No significant differences between groups occurred regarding other seconder outcome parameters.Conclusions: There is no clinically significant difference between extraperitoneal cesarean section and transperitoneal cesarean on fetal delivery time. Extraperitoneal cesarean reduces postoperative pain, analgesic requirements, and improves oral tolerability.

RESUMO

Fever of unknown origin frequently remains a diagnostic challenge. Immunological diseases account for about 20- 30% cases of these fevers. We report the case of a boy who presented with high fever for 2 months and was finally diagnosed as a case of IgG4-related disease at the rectovesical pouch.

RESUMO

Adhesion barriers can be based on numerous substances. In the rat Optimized Peritoneal Adhesion Model (OPAM) the starch-based hemostats 4DryField and Arista were tested for their capability to act in a preventive manner against adhesion formation (applied as a powder that was mixed in situ with saline solution to form a barrier gel). Adhesions were scored using the established scoring systems by Lauder and Hoffmann, as well as histopathologically using the score by Zühlke. Animals receiving saline solution were used as controls. As previously published, 4DryField reduced peritoneal adhesions significantly. However, Arista did not lead to a statistically significant reduction of adhesion formation. When comparing 4DryField and Arista applied in the same manner, only 4DryField was significantly effective in preventing peritoneal adhesions. Histopathological evaluations confirmed the results of the macroscopic investigation, leading to the conclusion that starch-based hemostats do not generally have the capability to function as effective adhesion prevention devices.

RESUMO

Since its first description in 1992, laparoscopic adrenalectomy has become the standard of treatment for most benign and low grade small adrenal tumors but due to the low incidence of adrenal disease, it remains a rarely performed intervention outside referral or excellence centers. Although laparoscopic surgery had a positive impact on complications of adrenalectomy, surgical risk should be thoroughly assessed when it comes to secreting or large tumors. This is a retrospective analysis of laparoscopic adrenalectomies performed in the first 4 years of practice 2007-2010 - the early experience including the learning curve of the senior surgeon, and our late experience from 2016 to 2019. All interventions were performed by a single team led by a senior surgeon with extensive experience in advanced laparoscopic surgery, using the lateral transperitoneal approach. In total, 82 cases were included, out of 153 laparoscopic adrenalectomies performed between 2007 and 2019. Only one conversion was recorded during the early experience and two laparoscopic reinterventions were needed for hemostasis and drainage. Non-secreting adenoma was the most frequent indication for surgery (26 cases) followed by Cushing's Syndrome (22 cases) while adrenocortical carcinoma was diagnosed in 3 cases. Significant differences were found between the two periods regarding operative time and length of postoperative hospital stay (p 0.001). With growing experience in laparoscopic transperitoneal adrenalectomy, less complications and shorter operative time and postoperative hospital stay are to be expected.

RESUMO

PURPOSE: Ovarian cancer (OC) is the commonest cause of death by gynaecological cancer in developed countries. Peritoneal carcinomatosis (PC) complete debulking without residual disease of >1 cm is the best prognostic predictor in advanced OC. PC is assessed with Computed tomography (CT). CT accuracy and cytoreduction success predictive ability are limited. PET/CT is not an imaging standard for PC. PC shows high signal foci in Diffusion-weighted magnetic resonance imaging (DWI MRI). We assessed the diagnostic performance (DP) and tumour burden correlation of Whole body DWI with background suppression MRI (WB-DWIBS/MRI) in PC of suspected OC using the Peritoneal Cancer Index (PCI), referring to cytoreduction surgery as the standard reference. METHOD: Fifty patients with suspicion of disseminated OC underwent cytoreduction and WB-DWIBS/MRI. The PCI scores tumour burden (0-3) in 13 anatomical regions (global range of 0-39). Two radiologists (Rad1/Rad2) assessed the PCI preoperatively and with surgical findings. We evaluated regional and global DP, the interobserver agreement (Cohen´s kappa coefficient), statistical differences (McNemar test) and tumour burden (Pearson's test). RESULTS: 72% (36/50) were epithelial OC and 78% (39/50) achieved complete cytoreduction. Global-PCI correlation was 0.762 (Rad1) with DP: Sensitivity 0.84, specificity 0.89, accuracy 0.89, and kappa 0.41. Average global-PCI was 7. The pelvis and right hypochondrium showed the highest positive rate and DP, while the intestinal regions presented the lowest. Previous studies reported higher sensitivity than CT or PET/CT, although only a few used the PCI. CONCLUSIONS: WB-DWIBS/MRI is reliable to depict, quantify and to predict complete cytoreductive surgery in OC PC.

RESUMO

BACKGROUND-PURPOSE: Totally extraperitoneal (TEP) endoscopic hernioplasty and Lichtenstein hernioplasty are the most commonly used approaches for inguinal hernia repair. However, current evidence on which is the preferred approach is inconclusive. This updated meta-analysis was conducted to track the accumulation of evidence over time. METHODS: Studies were identified by a systematic literature search of the EMBASE, PubMed, Cochrane Library, and Google Scholar databases. Fixed- and random-effects models were used to cumulatively assess the accumulation of evidence over time. RESULTS: The TEP cohort showed significantly higher rates of recurrences and vascular injuries compared to the Lichtenstein cohort; [Peto Odds ratio (OR) = 1.58 (1.22, 2.04), p = 0.005], [Peto OR = 2.49 (1.05, 5.88), p = 0.04], respectively. In contrast, haematoma formation rate, time to return to usual activities, and local paraesthesia were significantly lower in the TEP cohort compared to the Lichtenstein cohort; [Peto OR = 0.26 (0.16, 0.41), p ≤ 0.001], [mean difference = - 6.32 (- 8.17, - 4.48), p ≤ 0.001], [Peto OR = 0.26 (0.17, 0.40), p ≤ 0.001], respectively. CONCLUSIONS: This study, which is based on randomised-controlled trials (RCTs) of high quality, showed significantly higher rates of recurrences and vascular injuries in the TEP cohort than in the Lichtenstein cohort. In contrast, rate of postoperative haematoma formation, local paraesthesia, and time to return to usual activities were significantly lower in the TEP cohort than in the Lichtenstein cohort. Future multicentre RCTs with strict adherence to the standards recommended in the Consolidated Standards of Reporting Trials guidelines will shed further light on the topic.

RESUMO

To investigate the feasibility, efficacy, and safety of laparoscopic totally extraperitoneal (TEP) repair in patients with inguinal hernia accompanied by liver cirrhosis.Between October 2015 and May 2018, 17 patients with liver cirrhosis who underwent TEP repair were included in this study. The baseline characteristics, perioperative data, and recurrence were retrospectively reviewed.Seventeen patients with a mean duration of 18.23 ± 16.80 months were enrolled. All TEP repairs were successful without conversion to trans-abdominal pre-peritoneal (TAPP) surgery or open repair, but 4 patients had peritoneum rupture during dissection. The mean operation time was 54.23 ±â€Š10.51 minutes for unilateral hernia and 101.25 ±â€Š13.77 minutes for bilateral hernias. We found 2 cases with contralateral inguinal hernia and 2 cases with obturator hernia during surgery. The rate of complication was 17.65% (3/17), 2 of 3 cases were Child-Turcotte-Pugh C with large ascites. During a follow-up of 19.29 ±â€Š9.01 months, no patients had recurrence and chronic pain, but 2 patients died because of the progression of underlying liver disease.Early and elective inguinal hernia repair is feasible and effective for patients with liver cirrhosis. TEP is a feasible and safe repair option for cirrhotic patients in experienced hands.

RESUMO

OBJECTIVE: This study investigates the diagnostic power of CT scan combined with exploratory laparoscopy (EXL) at identifying large bowel involvement in patients with stage IIIC-IV primary Epithelial Ovarian Cancer (EOC) by comparing with the macroscopic surgical findings at laparotomy. METHODS: All patients with FIGO Stage IIIC-IV EOC who had Visceral Peritoneal Debulking (VPD) were included in the study. Results of CT scan, EXL and laparotomy (LPT) with regards to the bowel involvement were prospectively recorded in an ad hoc study form. Setting LPT findings as the gold standard, positive and negative predictive value (PPV/NPV), sensitivity, specificity and accuracy of CT and EXL were calculated. In addition, the diagnostic power of the combination CT scan + EXL was investigated. RESULTS: Ninety-four out of 177 patients (53.2%) had a bowel resection during VPD. CT-scan alone had sensitivity, specificity, PPV, NPV and accuracy of 56.7%, 72.4%, 70.8%, 58.5% and 63.8% respectively. EXL alone 84.4%, 93.8%, 93.8%, 84.3%, 88.8%. CT combined with EXL detected bowel involvement with a sensitivity, specificity, PPV, NPV and accuracy of 87.5%, 70.4%, 77.8%, 82.6% and 79.6% and respectively. The combined tests showed a statistically significant improvement vs. CT scan alone (p < 0001) in sensitivity, NPV and accuracy, with non-significant difference in specificity and PPV. CONCLUSIONS: CT-scan alone shows a limited diagnostic power at detecting large bowel involvement in patients with stage IIIC-IV EOC. The combination of CT scan with EXL increases the diagnostic power and enables to appropriately plan the bowel resection and consent the patients.

RESUMO

BACKGROUND: Whether patients with advanced tubo-ovarian high-grade serous cancer (HGSC) fare better after upfront debulking surgery (UDS) or neoadjuvant chemotherapy with interval debulking surgery (NACT-IDS) remains controversial. METHODS: We studied patients with HGSC who underwent UDS or NACT-IDS between July 2000 and December 2015, with peritonectomy procedures combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Clinical reports were included peritoneal cancer index (PCI), NACT responses, surgical complexity score (SCS), completeness of cytoreduction (CC), complete follow-up with timing, site, and treatment of recurrence. Outcome measures were morbidity, progression-free survival (PFS), PFS2, and overall survival during a mean 5-year follow-up. RESULTS: A total of 34 patients (23.6%) underwent UDS and 110 (76.4%) NACT-IDS both combined with HIPEC. At a median 66.3-month follow-up, patients who underwent UDS or NACT-IDS had similar outcomes. NACT subgroup responses correlated with PCI, SCS, morbidity, and CC. Patients who underwent UDS had lower recurrence rates than those who responded partly or poorly to NACT (PFS, P < .04; PFS2, P < .01). Despite HIPEC, the peritoneal disease recurred in 42.5% of the overall patients. CONCLUSION: In patients with primary HGSC who undergo UDS or NACT-IDS, despite similar outcomes, peritonectomy procedures combined with HIPEC seem unable to prevent peritoneal recurrence.

RESUMO

OBJECTIVES: To determine if intraperitoneal (IP) ports placed concurrently with bowel resection during surgical treatment of ovarian cancer is associated with more complications than those ports placed without concurrent bowel resection. METHODS: The medical records of all patients who had an IP port placed at our institution between 2005 and 2016 were reviewed. Two groups were analyzed: IP ports placed with bowel resection (IP-BR) and those without (IP). RESULTS: Of 306 patient charts reviewed, 31% had a surgery with IP port placement and concurrent bowel resection (IP-BR). Demographics were similar except for mean BMI (25.6 IP-BR vs 27.4 IP, p = 0.007). More IP-BR patients had stage IIIC disease (83.3% IP-BR vs 56.9% IP, p ≤0.01). Patients were cytoreduced to R0 in 48.7% IP-BR vs 56.4% IP (p = 0.253). For adjuvant treatment, IV chemotherapy was administered before IP chemotherapy in 90.4% IP-BR (median 2 cycles), and 50.3% IP, (median 2 cycles, p < 0.01). Ultimately 80.2% IP-BR (median 4 cycles) and 77.8% IP (median 5 cycles) received IP chemotherapy (p = 0.65). Rates of total IP port complications were similar (19.2% IP-BR vs 23.2% IP, p = 0.397), including IP port infections (0% IP-BR vs 0.7% IP, p = 0.5). Eleven percent of IP-BR patients had a bowel complication (e.g. obstruction or perforation) while IP port was in situ vs 2.7% IP (p = 0.01). Only 2.7% IP-BR and 6% IP discontinued IP chemotherapy due to IP port complication (p = 0.3). CONCLUSIONS: Patients who have IP ports placed concurrently with a bowel resection do not appear to have more complications, nor lower rates of IP chemotherapy administration.

RESUMO

Background: Complete cytoreduction is acknowledged to be an effective way to achieve macroscopic tumor clearance for a variety of tumors confined to the peritoneal cavity. Recent trials have shown that surgery respecting anatomical planes results in excellent outcomes and even the chance of cure for some from what was once thought to be life-limiting disease. Objective: To describe peritonectomy procedures in the current era. Method: A thorough and systematic method for cytoreductive surgery aimed at complete surgical resection of peritoneal metastases (PMs) was described. Results: The general principles of cytoreductive surgery were set out including preoperative preparation, patient positioning and incision. Strategies for assessing disease extent and planning surgical steps were outlined and established peritonectomy procedures such as Glisson's capsulectomy, omentectomy, left and right diaphragmatic peritonectomy, lesser omentectomy, stripping of the omental bursa, and pelvic peritonectomy were described. Novel techniques such as anterior pancreatic peritonectomy, small bowel mesenteric peritonectomy and cardiophrenic lymph node dissection were explained, and illustrated with accompanying video. Conclusion: Peritoneal metastases present a challenge to the surgeon which calls for a unique skill set if optimal outcomes are to be achieved. Attempts to standardize the surgical techniques described will allow further refinement as new technological advances occur.

RESUMO

OBJECTIVE: Laparoscopic totally extraperitoneal inguinal hernia repair (TEP) can be performed using either telescopic (TD) or balloon dissection (BD). The use of a disposable balloon dissector increases the cost of TEP. However, it remains unclear whether BD saves enough time to justify its cost. We hypothesized that BD would consistently save 15 min in operative time. To test this hypothesis, we designed a registry-based randomized controlled trial (RB-RCT) embedded into the Americas Hernia Society Quality Collaborative. METHODS: A single-blinded, parallel, RB-RCT was conducted. Adults with inguinal hernias presenting for elective repair were screened. Patients with unilateral hernias deemed fit to undergo TEP were eligible; those with bilateral hernias (BIH) or undergoing open repair were excluded. Individuals were randomized to TD or BD with a disposable device. TEP was performed with synthetic mesh and tacks. Subjects were blinded and followed up for 30 day. Main outcome was operative time. RESULTS: 207 patients were screened: 166 were excluded and 41 were randomized (21 BD, 20 TD). One patient (TD group) was excluded due to the incidental finding of BIH. 40 patients were analyzed (median age 56, median BMI 26 kg/m2, 98% males). Hernias were 72% indirect, 17% direct, 10% pantaloon, and 8% recurrent. Other than obesity (26.5% vs. 0, p = 0.018), there were no baseline differences between the groups. Median operative times were similar (TD 43 min, IQR 33-63; BD 46 min, IQR 35-90, p = 0.490). There were 2 seromas and 2 hematomas in the BD group, and none in the TD (p = 0.108). CONCLUSIONS: BD does not consistently result in 15-min time saving during TEP. Use of a disposable balloon dissector can be deferred in the experienced hands. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03276871).

RESUMO

Transplantation of cryopreserved ovarian tissue offers patients a chance to preserve fertility during cancer treatment. In this study of ten young women with gynecological cancer, heterotopic sites were tested for serum hormones and follicle growth to estimate transplant longevity and prospects for assisted conception. Frozen-thawed grafts were implanted subcutaneously in the forearm (FA) (2 cases), the abdominal wall (AW) (11 cases), and the peritoneal lining (P) (3 cases) . In the follow-up of 36 months, a total of 80 ovarian cycles in different heterotopic sites were analyzed. FA and AW grafts had wildly fluctuating FSH, while estradiol (E2) reached preovulatory levels only in AW and P grafts. Follicular growth was active in P sites (1.2 ± 0.1 mm/d) and sluggish in FA and AW sites (0.4 ± 0.1 mm/d). A mature oocyte was only retrieved from the AW, while seven other aspirations were unsuccessful. Meanwhile, a patient delivered twice after treatment for Hodgkin's lymphoma when orthotopic transplantation was performed, first from an IVF cycle and subsequently from a natural cycle. In conclusion, these findings offer no strong encouragement for fertility preservation by transplanting cryopreserved ovarian tissue to subcutaneous sites, and although the peritoneal site gave better results, graft longevity averaged the same at around 3 years.

RESUMO

The peritoneum is a common site of dissemination for colorrectal cancer, with a poorer prognosis than other sites of metastases. In the last two decades, it has been considered as a locoregional disease progression and treated as such with curative intention treatments. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the actual reference treatment for these patients as better survival results have been reached as compared to systemic chemotherapy alone, but its therapeutic efficacy is still under debate. Actual guidelines recommend that the management of colorectal cancer with peritoneal metastases should be led by a multidisciplinary team carried out in experienced centers and consider CRS + HIPEC for selected patients. Accumulative evidence in the last three years suggests that this is a curative treatment that may improve patients disease-free survival, decrease the risk of recurrence, and does not increase the risk of treatment-related mortality. In this review we aim to gather the latest results from referral centers and opinions from experts about the effectiveness and feasibility of CRS + HIPEC for treating peritoneal disease from colorectal malignancies.

RESUMO

INTRODUCTION: The National Comprehensive Cancer Network (NCCN) guidelines recommend intraperitoneal chemotherapy in optimally debulked stage III ovarian cancer patients. The objective of this investigation was to determine the rate of intraperitoneal port placement in patients undergoing surgery for ovarian cancer in a national database maintained by the American College of Surgeons. METHOD: We identified ovarian cancer patients in the National Surgical Quality Improvement Program database from 2006 to 2012. Demographics, comorbidities, operative outcomes, and postoperative complications were abstracted. Descriptive analyses were conducted using Wilcoxon rank-sum and Chi square tests, and multivariate regression models were used to analyze pre-operative and post-operative variables associated with intraperitoneal port placement. RESULTS: We identified 2659 ovarian cancer patients who underwent primary surgical management. Of these patients, only 128 (4.8%) had an intraperitoneal port placed at the time of surgery. In multivariable analyses, intraperitoneal ports were associated with body mass index ≤25, disseminated cancer, later portion of the study period (2009-2012), and operative time >200 min. Intraperitoneal port placement was not associated with any difference in surgical site infection, wound disruption, major postoperative complication, readmission within 30 days, or death within 30 days. DISCUSSION: Recent investigation of practice at NCCN institutions between 2003 and 2012 found only 35% of eligible ovarian cancer patients received intraperitoneal chemotherapy. Using intraperitoneal port placement as a surrogate for intraperitoneal chemotherapy administration, our investigation suggests an even lower rate (4.8%) nationally.

RESUMO

Objective: To investigate the feasibility and safety of the medial approach "four-step method" in the laparoscopic mobilization of splenic flexure. Methods: A retrospective cohort study was performed. Clinical data of 157 colorectal cancer patients undergoing the medial approach "four-step method" in the laparoscopic mobilization of splenic flexure at Gastrointestinal Surgical Department of Guangdong Provincial People's Hospital from July 2015 to June 2018 were retrospectively analyzed. Of 157 cases, 17 were transverse colon cancer, 94 were descending colon cancer, 25 were sigmoid cancer and 21 were rectal cancer; 89 were male and 68 were female; mean age was (61.8±10.3) years and mean body mass index was (23.2±3.7) kg/m(2). The medial approach "four-step method" in the laparoscopic mobilization of splenic flexure was performed as follows: (1) The root vessels were treated with the "provocation" technique to expand the Toldt's gap. This expansion was extended from the lateral side to the peritoneum reflex of left colonic sulcus, from the caudal side to the posterior rectal space, and from the cephalad side to the lower edge of pancreas. (2) The left colonic sulcus was mobilized, converging with the posterior Toldt's gap. Mobilization was carried out from cephalad side to descending colon flexure, freeing and cutting phrenicocolic ligament and splenocolic ligament, and from caudal side to peritoneal reflex. (3) Gastrocolic ligament was moblized. Whether to enter the great curvature of stomach omentum arch when the gastrocolic ligament was cut, that was, whether to clean the fourth group of lymph nodes, should be according to the tumor site and whether serosal layer was invaded. (4) Transverse mesocolon was moblized and transected at the lower edge of the pancreatic surface, merging with the posterior Toldt's gap, and from lateral side to lower edge of the pancreatic body, merging with the lateral left paracolonic sulcus. Safety and short-term clinical efficacy of this surgical procedure was summarized. Results: All the patients completed this procedure. During operation, 3 cases were complicated with organ injury, including 1 case of colon injury, 1 case of spleen injury and 1 case of pancreas injury. No operative death and conversion to open surgery was found. The average operation time was (147.5±35.1) minutes, the average intra-operative blood loss was (40.8±32.7) ml and the average number of harvested lymph node was (16.1±5.8), including (4.0±2.3) of positive lymph nodes. The first exhaust time after surgery was (41.3±20.6) hours, the fluid intake time was (1.5±1.3) days, the postoperative hospital stay was (5.2±2.3) days. Eight (5.1%) cases developed postoperative complications, and all were improved and discharged after conservative treatments. According to the TNM classification system, postoperative pathology revealed that 31 patients were stage I, 51 were stage II, 53 were stage III, 22 were stage IV. Conclusion: The medial approach "four-step method" is safe and feasible, which can effectively decrease the operation difficulty of the laparoscopic mobilization of the splenic flexure.

RESUMO

OBJECTIVE: Despite advances in diffuse peritonitis treatment protocols, some cases develop unfavorably. With the advent of vacuum therapy, the use of laparostomy to treat peritonitis has gained traction. Another treatment modality is continuous peritoneal lavage. However, maintaining this technique is difficult and has been associated with controversial results. We propose a new model of continuous peritoneal lavage that takes advantage of the features and benefits of vacuum laparostomy. METHOD: Pigs (Landrace and Large White) under general anesthesia were submitted to laparostomy through which a multiperforated tube was placed along each flank and exteriorized in the left and lower right quadrants. A vacuum dressing was applied, and intermittent negative pressure was maintained. Peritoneal dialysis solution (PDS) was then infused through the tubes for 36 hours. The stability of peritoneostomy with intermittent infusion of fluids, the system resistance to obstruction and leakage, water balance, hemodynamic and biochemical parameters were evaluated. Fluid disposition in the abdominal cavity was analyzed through CT. RESULTS: Even when negative pressure was not applied, the dressing maintained the integrity of the system, and there were no leaks or blockage of the catheters during the procedure. The aspirated volume by vacuum laparostomy was similar to the infused volume (9073.5±1496.35 mL versus 10165±235.73 mL, p=0.25), and there were no major changes in hemodynamic or biochemical analysis. According to CT images, 60 ml/kg PDS was sufficient to occupy all intra-abdominal spaces. CONCLUSION: Continuous peritoneal lavage with negative pressure proved to be technically possible and may be an option in the treatment of diffuse peritonitis.
