Abstract
Background Uncontrolled and diffuse bleeding is a dreaded event during open and laparoscopic surgery that may lead to postoperative complications, obstruction of the surgical field that reduces visualization, and prolonged operating times. Powder hemostats can be used to control bleeding and are easy to use, have a safe profile, and can achieve broad coverage area at a low cost. Methods A strategic literature search of peer-reviewed, English language studies was conducted to capture evidence on the clinical efficacy and safety of a Microporous Polysaccharide Hemosphere (MPH) based Hemostat (Arista™ Absorbable Hemostat (Arista™ AH)). Results Six preclinical studies were found which supported the use of MPH in various animal models of laparoscopic and open surgery, all of which demonstrated its safety and efficacy. Five single-arm and 11 comparative clinical studies similarly supported the efficacy and safety of MPH in various surgery types, including cardiac, renal, and dermatologic surgery. Conclusion Published evidence supports the safe and effective use of MPH across a variety of surgical settings.

Abstract
Background Endometriosis is a chronic inflammatory oestrogen-dependent disease. It is characterised by elevated inflammatory markers in the peritoneal milieu with subsequent adhesiogenesis. Nowadays, excisional, and ablative surgeries are considered the main treatment of endometriosis, and adhesiolysis is being performed almost routinely during these procedures. Postoperative adhesion formation is a significant concern for many surgeons, especially as endometriosis patients are assumed to be predisposed to adhesiogenesis. In order to minimise adhesiogenesis after endometriosis surgery, the usage of different barrier methods have been discussed in the literature. Recent studies aim to investigate the effect of potato starch preparations on adhesion formation in endometriosis patients. Objectives We aim to describe the findings of a second-look laparoscopy on patients who received a starch-based anti-adhesive agent. Materials and Methods We present a retrospective case series that included the medical, surgical, and histopathologic data of three patients. Main outcome measures Intraperitoneal adhesion formation and peritoneal inflammation. Results All three patients had de-novo adhesions during the second-look laparoscopy. Pathological examination revealed noncaseating granulomatosis of the peritoneum in all patients. Conclusion The use of potato starch-based agents as a peritoneal adhesion prophylaxis in laparoscopic endometriosis surgery could lead to granulomatous peritoneal inflammation. Correct application by avoiding powder remnants through complete rinsing and transformation to gel seems to be an important factor to avoid this adverse effect. What is new? We aim to highlight that potato starch-based anti-adhesive agents similar to the one used in this study could be a cause of adhesiogenesis and peritoneal inflammation.

Abstract
Background Adhesions within the abdominal cavity develop in as many as 90 % of individuals following abdominal surgery. However, the true adhesive condition of patients can only be ascertained during the second surgery. Methods We conducted a prospective, non-randomized study to assess the anti-adhesion properties of purified starch in patients who had undergone colorectal surgery in the past and then needed a subsequent surgical intervention. Adhesion scores have been prospectively recorded in operation notes since January 2020 when patients underwent a second surgery. Patients who had received purified starch during their initial surgery constituted the purified starch group, while those who had not received anti-adhesion medical materials were the control group. The main objectives of the study were to evaluate the extent and severity of adhesions as primary outcomes, while secondary outcomes included measuring blood loss, operation time, and postoperative complications. Results We analyzed the data of 101 patients, with 61 in the purified starch group and 40 in the control group. In multivariate analysis, adhesion severity (Odds ratio, 0.20, 95 % confidence interval 0.08-0.54, P < 0.01) and adhesion area scores (Odds ratio, 0.13, 95 % confidence interval 0.04-0.45, P < 0.01) were significantly lower in the purified starch group than in the control group. There was no significant difference in operation times, blood loss, and postoperative complications between the two groups. Conclusion Purified starch is a safe and effective anti-adhesion material that can significantly reduce the severity and extent of adhesion after colorectal surgery.

Improvement in Fertility and Pain after Endometriosis Resection and Adhesion Prevention with 4DryField ® PH: Follow-up of a Randomized Controlled Clinical Trial. J Clin Med 2023; 12:jcm12103597. [PMID: 37240703 DOI: 10.3390/jcm12103597] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/06/2023] [Accepted: 05/16/2023] [Indexed: 05/28/2023] Open
Abstract
BACKGROUND Adhesions after endometriosis resection are frequent and the most common causes for chronic pain and secondary infertility. Primary results of our randomized controlled trial (RCT) on adhesion prevention after deep infiltrating endometriosis (DIE) resection using the gel barrier 4DryField® PH showed 85% adhesion reduction in second-look surgeries. Secondary endpoint data on fertility and pain development were collected during 12-month follow-ups. METHODS This RCT comprised 50 patients. Preoperatively and after 1, 6 and 12 months, pain scores for cycle-independent pelvic pain, dysmenorrhea, dyspareunia, dyschezia, and dysuria, as well as the number of pregnancies, were recorded,. RESULTS The pregnancy rate in the intervention group was significantly higher (p < 0.05). Pain development was also improved: after 12 months, all 5 subscores were lower in the intervention group and improvements were more pronounced, most prominently concerning cycle-independent pelvic pain and dysmenorrhea, the two subcategories with the highest preoperative scores and, therefore, the highest relevance for the patients. Cycle-independent pelvic pain even recurred in the control group, while barrier application prevented this. CONCLUSIONS Considering the known causal link between adhesions and pain, it is apparent that the favourable outcomes in the intervention group are linked to effective adhesion prevention. The significant increase in pregnancies is remarkable.

Abstract
Adhesions formation after surgery for congenital heart defects can complicate follow-up procedures due to bleeding from detached adhesion bands, injury to cardiac structures or large vessels, all of which do prolong operation times. The problem is enhanced by the fact that detached adhesions are predilection sites for new adhesions setting off a downward spiral. 4DryField® PH gel barrier has demonstrated high efficacy in reducing postoperative adhesions in general surgical and gynecological studies. This retrospective controlled study of 22 patients evaluates whether these positive results can be confirmed in pediatric cardiac surgery. Adhesions were scored from photographs of follow-up interventions by an independent cardiac surgeon blinded to group assignment. The publication provides not only score numbers but also original photographs of all sites for better traceability and transparency. In addition, timesaving due to reduced adhesions was evaluated. Results show a significantly reduced adhesion score for the 4DryField® group. Importantly, this resulted in a significantly shorter period between skin incision and start of cardiopulmonary bypass. In addition, timesaving due reduced adhesion formation was evaluated. The use of 4DryField® was safe, although higher doses per kg were used than in adults.

Abstract
Postoperative adhesions represent a frequent complication of abdominal surgery. Adhesions can result from infection, ischemia, and foreign body reaction, but commonly develop after any surgical procedure. The morbidity caused by adhesions affects quality of life and, therefore, it is paramount to continue to raise awareness and scientific recognition of the burden of adhesions in healthcare and clinical research. This 2021 Global Expert Consensus Group worked together to produce consented statements to guide future clinical research trials and advise regulatory authorities. It is critical to harmonize the expectations of research, to both develop and bring to market improved anti-adhesion therapies, with the ultimate, shared goal of improved patient outcomes.

Abstract
Adhesions are a common consequence of abdomino-pelvic surgery. Efficacy of available adhesion prevention agents is discussed controversially. Here, we used the adhesion barrier 4DryField PH: a powder, which is transformed into a barrier gel with saline solution. The study includes 40 consecutive patients with surgeries for adhesiolysis, endometriosis and other gynaecological pathologies and subsequent second look interventions. The intervention group (n = 17) received 4DryField PH gel while control patients (n = 23) did not receive any adhesion prevention. Severity and extent of adhesion formation were scored during both interventions using an established score. Direct comparison between first and second interventions showed that extent and severity of adhesions could be reduced significantly using 4DryField PH gel. In contrast, in the control group, extent was not reduced and severity was even significantly higher. Direct comparison of second look laparoscopies revealed that adhesion extent and severity were significantly lower in the 4DryField PH than in the control group.Impact StatementWhat is already known on this subject? Adhesion formation after gynaecologic surgeries is known to be frequent and highly problematic as it directly induces complications and additionally makes subsequent surgeries more difficult. The effectiveness of established adhesion barriers is not sufficient to tackle these problems adequately.What the results of this study add? This is the first controlled study using the relatively new adhesion barrier 4DryField PH. It yields a significant reduction of extent as well as severity of adhesions, while adhesiolysis surgery alone does not solve the problem.What the implications are of these findings for clinical practice and/or further research? Usage of 4DryField PH gel seems to be a good approach to solve the adhesion problem of gynaecologic surgery in general and the reformation problem of adhesiolysis surgery specifically. The results should be confirmed in a larger prospective randomised controlled trial.

Abstract
Introduction The development of peritoneal adhesions and the effects of different antiadhesion agents on such mechanisms are not fully understood. Temporary rises of the C-reactive protein (CRP) level have been reported after antiadhesion agent application. We present the changes of inflammation markers observed after use of a starch-based polysaccharide certified for adhesion prevention and hemostasis 4DF (4DryField® PH). Method Retrospective comparative analysis of inflammation markers in 40 patients undergoing laparoscopic adhesiolysis with or without adhesion prophylaxis was conducted. Statistical comparisons were performed by means of paired or unpaired t tests (for normally distributed continuous data), Wilcoxon matched pairs signed-rank tests or Mann–Whitney tests (for not-normally distributed continuous data), Mantel–Cox tests (for continuous data describing time intervals), and Fisher’s exact tests (for discrete data). Results The maximum post-operative CRP level was significantly elevated in the 4DF group (87 vs. 29%; p < 0.001), whereas leukocyte concentration and body temperature did not differ between groups. No signs of infection were detected in any of the patients and CRP levels spontaneously dropped to normal values within few days. No side effects or complications were observed in both groups. In second-look surgeries performed for other diagnoses 1–56 weeks after the first interventions, no remnants of 4DF or any peritoneal inflammatory reactions were observed. Conclusion The starch-based polysaccharide 4DF can be considered safe and does not induce inflammatory reactions of clinical significance. Further studies regarding 4DF degradation are recommended and, apart from macrophage migration, could also examine corresponding markers such as IL-6 and PCT.

An international multidisciplinary peer-driven consensus on the optimal use of hemostatic powders in surgical practice. Updates Surg 2021; 73:1267-1273.

Abstract
Bleeding is a consequence of insufficient hemostasis and excessive bleeding at a surgical site is associated with an increased risk of post-operative infection, transfusion and re-operation, in addition to increased hospital length of stay and costs. Surgeons employ a range of methods to achieve hemostasis, including topical hemostatic agents of differing composition and properties. Hemostatic powders are a sub-group of topical hemostats, which can be used in helping as adjuncts to manage troublesome bleeding in a variety of situations. As this technology is relatively new and potentially not well known by the broad surgical community, no specific guidelines or recommendations for the optimal use of hemostatic powders in surgery currently exist. A steering group throughout Europe of multidisciplinary surgeons, expert in hemostasis and hemostatics, identified from literature and from personal experience, five key topics. When to use hemostatic powder, the evidence for use, benefits of use, safety remarks and considerations in various surgical specialties. Thirty-seven statements were subsequently drawn from these five key topics. An online survey was sent to 128 high-volume surgeons working in breast surgery, gynaecological and obstetric surgery, general and emergency surgery, thoracic surgery and urological surgery in Europe to assess agreement (consensus) with these statements. Consensus was defined as high if ≥ 75% and very high if ≥ 90% of respondents agreed with a statement. A total of 79 responses were received and consensus among the surgical experts was very high in 27 (73%) statements, high in 8 (22%) statements and was not achieved in 2 (5%) statements. Based on the consensus scores, the steering group produced 16 key recommendations which they considered could improve patient outcomes by reducing post-operative bleeding and its associated complications using hemostatic powder.

Abstract
Purpose Adhesion formation after endometriosis surgery is a severe problem affecting up to 90% of patients. Possible complications include chronic pain, ileus, and secondary infertility. Therefore, effective adhesion prophylaxis is desirable, for which the adhesion barrier 4DryField® PH is evaluated in the present clinical study. It is a starch-based powder that forms a gel after irrigation with saline solution and thus separates surgical sites as physical barrier for adhesion prevention. Methods Fifty patients with extensive and deep infiltrating endometriosis were included in this prospective, randomized, controlled clinical trial with two-staged laparoscopic approach. The patients were randomized into two groups, one receiving 4DryField® PH and the other irrigation with saline solution for adhesion prevention. Adhesion formation was directly scored during second-look interventions considering incidence, extent, and severity. Adhesion prevention treatment in the second surgery was performed corresponding to the first intervention to evaluate the long-term outcome in the later course. Results Both groups were comparable with respect to relevant patient parameters. Severity and extent of adhesions were significantly reduced by 85% in the 4DryField® PH group compared to the control group (mean total adhesion score 2.2 vs. 14.2; p = 0.004). Incidence of adhesion formation based on the number of affected sites was significantly reduced by 53% in the intervention vs. control group (mean 1.1 vs. 2.3 sites; p = 0.004). Follow-up of secondary endpoints is not yet completed; results will become available at a later stage. Conclusion Adhesion formation could be reduced significantly by 85% by application of the adhesion barrier 4DryField® PH.

Abstract
The development of adhesions after gynecologic surgery is a severe problem with ramifications that go beyond the medical complications patients suffer (which most often include pain, obstruction and infertility), since they also impose a huge financial burden on the health care system and increase the workload of surgeons and all personnel involved in surgical follow-up care. Surgical techniques to avoid adhesion formation have not proven to be sufficient and pharmaceutical approaches for their prevention are even less effective, which means that the use of adhesion prevention devices is essential for achieving decent prophylaxis. This review explores the wide range of adhesion prevention products currently available on the market. Particular emphasis is put on prospective randomized controlled clinical trials that include second-look interventions, as these offer the most solid evidence of efficacy. We focused on adhesion scores, which are the most common way to quantify adhesion formation. This enables a direct comparison of the efficacies of different devices. While the greatest amount of data are available for oxidized regenerated cellulose, the outcomes with this adhesion barrier are mediocre and several studies have shown little efficacy. The best results have been achieved using adhesion barriers based on either modified starch, i.e., 4DryField® PH (PlantTec Medical GmbH, Lüneburg, Germany), or expanded polytetrafluoroethylene, i.e., GoreTex (W.L. Gore & Associates, Inc., Medical Products Division, Flagstaff, AZ), albeit the latter, as a non-resorbable barrier, has a huge disadvantage of having to be surgically removed again. Therefore, 4DryField® PH currently appears to be a promising approach and further studies are recommended.

Abstract
BACKGROUND One of the most common complications of hip arthroplasty is excessive blood loss that could necessitate allogenic blood transfusion, which is further associated with other complications, such as infections, transfusion reactions or immunomodulation. In gynecology, 4DryField®PH, an absorbable polysaccharide-based formulation, is used for hemostasis and adhesion prophylaxis. In this study, we evaluated its hemostatic effect in patients undergoing hip bipolar hemiarthroplasty following intracapsular femoral neck fracture. METHODS We studied 40 patients with intracapsular femoral neck fractures (Garden III or IV) admitted at our institution between July 2016 and November 2017. We included patients above 60 years with simple fracture and without pathologic fractures. Patients were randomized into intervention and control groups. The intervention group received 5 g of 4DryField® PH (subfascially and subcutaneously) during wound closure. Three drainages were inserted in a standardized manner (submuscular, subfascial, and subcutaneous) and drainage volume was measured immediately before extraction. Total blood loss was calculated using Mercuriali's formula and standard hemograms upon admission and five days after surgery. Volume of postoperative hematoma was measured using point-of-care ultrasound seven days after surgery. RESULTS Volume of the postoperative hematoma was reduced by 43.0 mL. However, significant reduction of total blood loss and drainage volume was not observed. CONCLUSIONS We observed that 4DryField® PH had a local hemostatic effect, thereby reducing volume of the postoperative hematoma. However, this reduction was small and had no effect on the total blood loss. Further studies are warranted to improve the application algorithm.

Abstract
PURPOSE Deep ovarian endometriosis surgery is likely to be associated with diffuse bleeding, intraoperative ovarian tissue destruction and perioperative adhesion formation. A new surgical approach is hereby proposed to avoid the negative short-term impact of classic laparoscopic cystectomy on ovarian reserve. RESULTS The need for intraoperative periovarian coagulation after endometrioma excision was avoided by combining the gold standard minimal-access endometrioma stripping technique with a purely plant-based medical product with high-hemostatic and antiadhesion barrier properties. CONCLUSION Endometrioma stripping followed by the application of a polysaccharide agent could avoid ovarian failure and at same time could reduce adhesion formation, thereby preserving tubo-ovarian function in endometrioma surgery. We encourage other surgically working groups to investigate middle- and long-term effects of this combined technique.

Lymphostasis and Hemostasis in Body-Contouring Surgery Using a Polysaccharide Based Hemostat (4DryField PH). PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2128. [PMID: 31044110 PMCID: PMC6467625 DOI: 10.1097/gox.0000000000002128] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 12/12/2018] [Indexed: 11/25/2022]
Abstract
Background: Following liposuction, abdominoplasty is the most frequent body-contouring intervention in the world. The transection of small blood vessels in large areas and subsequent bleeding is a viable risk during this procedure. The resulting microvascular bleedings should be stopped thoroughly to reduce the probability of related complications. In this prospective, monocentric, randomized study, the efficacy of the polysaccharide-based hemostat 4DryField PH (4DF) (PlanTec Medical, Lueneburg, Germany) is examined in classic abdominoplasty and lower body lift after Lockwood. Methods: For this prospective, monocentric, randomized study, 40 patients underwent surgery for both interventions. Twenty patients received an abdominoplasty, and 20 patients underwent a body lift. In each group, 10 patients have been treated with 4DF, whereas 10 have been served as the untreated control group. Results: 4DF had neither a beneficial nor a negative effect on necessity of drainages, drainage volume and duration, length of hospital stay or frequency of postoperative seromas, wound healing disturbances, and infections, independent of surgical intervention. Patients in the 4DF group, however, had more individual risk factors, and required extended surgical interventions that might mask primary outcome results. Conclusions: This is the first prospective, monocentric, randomized study on 4DF in body-contouring surgery. The use of 4DF did not lead to a better postoperative outcome regarding hemostasis and lymphostasis. Potential benefits need further evaluation in high-volume studies.

Abstract
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.

The sticky business of adhesion prevention in minimally invasive gynecologic surgery. Curr Opin Obstet Gynecol 2018; 29:266-275.

Abstract
PURPOSE OF REVIEW The negative impact of postoperative adhesions has long been recognized, but available options for prevention remain limited. Minimally invasive surgery is associated with decreased adhesion formation due to meticulous dissection with gentile tissue handling, improved hemostasis, and limiting exposure to reactive foreign material; however, there is conflicting evidence on the clinical significance of adhesion-related disease when compared to open surgery. Laparoscopic surgery does not guarantee the prevention of adhesions because longer operative times and high insufflation pressure can promote adhesion formation. Adhesion barriers have been available since the 1980s, but uptake among surgeons remains low and there is no clear evidence that they reduce clinically significant outcomes such as chronic pain or infertility. In this article, we review the ongoing magnitude of adhesion-related complications in gynecologic surgery, currently available interventions and new research toward more effective adhesion prevention. RECENT FINDINGS Recent literature provides updated epidemiologic data and estimates of healthcare costs associated with adhesion-related complications. There have been important advances in our understanding of normal peritoneal healing and the pathophysiology of adhesions. Adhesion barriers continue to be tested for safety and effectiveness and new agents have shown promise in clinical studies. Finally, there are many experimental studies of new materials and pharmacologic and biologic prevention agents. SUMMARY There is great interest in new adhesion prevention technologies, but new agents are unlikely to be available for clinical use for many years. High-quality effectiveness and outcomes-related research is still needed.

Effect of 4DryField ® PH, a Novel Adhesion Barrier, on Recurrence of Intestinal Adhesions after Extensive Visceral Adhesiolysis. Case Rep Surg 2018; 2018:9628742. [PMID: 29713558 PMCID: PMC5866859 DOI: 10.1155/2018/9628742] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2017] [Accepted: 01/28/2018] [Indexed: 01/21/2023] Open
Abstract
Background Adhesions occur after up to 97% of abdominal interventions causing chronic pain, infertility, and intestinal obstruction. Various concepts to prevent adhesions have been presented but mostly either have low efficacy or are not applicable in resective intestinal surgery or incomplete hemostasis. In this retrospective one-center clinical trial, the course of patients with extensive abdominal adhesiolysis and application of a recent starch-based formulation, 4DryField PH (4DF), is analyzed. Case Report Five female patients (age 65–83 years) underwent extensive open adhesiolysis with application of 4DF gel for adhesion prevention, premixed extracorporeally with saline or Ringer's solution (60–70 mL per 5 g 4DF) for homogeneous gel distribution on intestinal loops and in the peritoneal cavity. In addition, dry 4DF powder was dispersed on the greater omentum and subsequently transformed into a gel by dripping with saline or Ringer's solution directly before abdominal closure. Patients were followed up for more than two years, except for one patient who died after nine months due to metastases. One patient with complex situation due to Gore-Tex mesh in the lower abdomen showed no adhesions at scheduled second-look operation but after six months had relaparotomy for adhesiolysis. All other patients have remained free of adhesions or adhesion-related symptoms during follow-up. Conclusion Considering the extent and complexity of adhesions, treatment with 4DF gel for adhesion prevention after open adhesiolysis appears promising. Prospective randomized trials should further elaborate on this clinical concept.

Uterine perforation following a fractional curettage successfully treated with the modified polysaccharide 4DryField® PH: a case report. J Med Case Rep 2016; 10:243.

Abstract
Background Uterine perforation is the most common complication of curettage and may result in bleeding. Therefore, urgent control of bleeding from the uterine wall perforation is necessary to avoid an emergency hysterectomy or blood transfusion, to prevent peritoneal adhesion formation, possible chronic pelvic pain, and infertility. In the present case, an active bleeding secondary to a perforation of the uterus during curettage, for diagnosis of endometrial carcinoma, was instantaneously and successfully treated with only the application of a novel modified polysaccharide powder. This is, to the best of our knowledge, the first time that the agent 4DryField® has been used for this purpose. Case presentation A 71-year-old German woman with serometra and endometrial hyperplasia suffered a perforation of the anterior wall of the uterus during the hysteroscopic resection of submucosal polyps and a fractional curettage. Subsequently, an immediate laparoscopy showed an active bleeding from the wound, which was promptly stopped with only the application of the hemostatic and anti-adhesion polysaccharide powder, 4DryField®. There were no postoperative complications. Nine weeks later, a laparoscopic hysterectomy with bilateral salpingoophorectomy for endometrial carcinoma (histology: stage IA, pT1a, cN0, L0 V0 M0/G2) was performed. The former injured area looked slightly prominent, was completely healed, and showed a shiny serosa. All her pelvic organs were free of adhesions, and there was one 0.5-mm calcified granuloma in the Douglas pouch. Conclusions The efficient hemostasis combined with the adhesion prevention effect of 4DryField®, allowed a fast control of the uterine wall bleeding, saved operation time, avoided the risks of other procedures for bleeding control and contributed to the normal healing of the uterine wall without any adhesion formation.

Abstract
Purpose. To investigate impact of polysaccharide hemostat 4DryField PH (4DF) applied on lymph node dissection area after radical retropubic prostatectomy (RRP) on lymphorrhea and lymphocele (LC) formation. Methods. 104 consecutive patients underwent RRP, 51 without 4DF treatment (CT-group) and 53 with 4DF treatment (4DF-group). Groups were comparable (age, risk profile, and lymph node numbers). Postoperative drain loss (PDL) and development of early and late LC were analyzed (mean follow-up at 7 months: 100%). Results. PDL was 452.5 ± 634.2 mL without and 308.5 ± 214 mL with 4DF treatment. PDL > 1000 mL only occurred in CT-group (5/51). Overall, 45 LC (26 in CT- versus 19 in the 4DF-group) were diagnosed. At day 8, LC were equally distributed between groups. Incidence of late LC, however, was twice in controls (16/51) versus 4DF-patients (8/53). Symptomatic LC (4 in untreated patients, 2 in 4DF-patients) were treated with percutaneous drainage (duration: 45 days in untreated patients versus 12 days in 4DF-patients). Conclusion. Application of 4DF on lymph node dissection areas lessened total drain loss and significantly lowered high volume drain loss. Furthermore, 4DF reduced frequency of late lymphoceles and lymphoceles requiring treatment by half, as well as duration of percutaneous drainage by more than two-thirds.

Abstract
Intra-abdominal adhesions are the most frequently occurring postoperative complication following abdomino-pelvic surgery. Abdominal and pelvic surgery can lead to peritoneal adhesion formation causing infertility, chronic pelvic pain, and intestinal obstruction. Laparoscopy today is considered the gold standard of care in the treatment of several abdominal pathologies as well as in a wide range of vascular diseases. Laparoscopy has several advantages in comparison to open surgery. These include rapid recovery times, shorter hospitalisation, reduced postoperative pain, as well as cosmetic benefits. The technological improvements in this particular surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its wider utilization in operations with fully intracorporeal anastomoses. Postoperative adhesions are caused by aberrant peritoneal healing and are the leading cause of postoperative bowel obstruction. The use of anti-adherence barriers is currently being advocated for their prevention. The outcome of the investigation showed adhesion formation inhibition without direct detrimental effects on anastomotic healing. Poor anasto-motic healing can provoke adhesions even in the presence of anti-adhesion barriers. This review gives a short overview on the current evidence on the pathophysiology and prevention of peritoneal adhesions.
