[PMID: 39177777 DOI: 10.1007/s00261-024-04527-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2024] [Revised: 08/06/2024] [Accepted: 08/10/2024] [Indexed: 08/24/2024]
Abstract
Pelvic adhesions are nonanatomic connections between organs and normal peritoneal surfaces that develop secondary to a maladaptive inflammatory response to tissue insults. Comprised of fibrous tissue, adhesions can result in the distortion of operative dissection planes, which can complicate the establishment of abdominal access in patients undergoing surgery, prolong the length of surgery, and increase the risk of injury to bowel and other structures if involved by extensive adhesive disease. This can adversely impact patient outcomes by increasing the risk of surgical complications including bleeding, infection, and prolonging postoperative length of stay. Literature on the characterization of adhesions with imaging is limited and a systematic framework for evaluating adhesive disease on cross-sectional imaging of the pelvis does not currently exist. In this review, we discuss the MR imaging features of pelvic adhesions, highlighting unique teaching cases in which surgical exploration was significantly complicated by the presence of adhesive disease. We will also review the correlation between MR imaging and intraoperative findings in these cases. A proposed standardized framework for the detection and characterization of adhesions on pelvic MRI will be reviewed with multiple imaging examples. Identification and characterization of pelvic adhesive disease on preoperative imaging provides radiologists with an opportunity to inform the referring clinician of their presence, potentially improving outcomes and the quality of patient care.

Abstract
BACKGROUND The effect of previous abdominal surgery (PAS) in laparoscopic surgery is well known and significantly adds to longer hospital length of stay (LOS), postoperative ileus, and inadvertent enterotomies. However, little evidence exists in patients with PAS undergoing robotic-assisted (RA) rectal surgery. METHODS All patients undergoing RA surgery for rectal cancer were reviewed. Patients with PAS were divided into minor and major PAS groups, defined as surgery involving >1 quadrant. The primary outcome was the risk of conversion to open surgery. RESULTS A total of 750 patients were included, 531 in the no-PAS (NPAS) group, 31 in the major PAS group, and 188 in the minor PAS group. Patients in the major PAS group had significantly longer hospital LOS (P < .001) and lower adherence to enhanced recovery pathways (ERPs; P = .004). The conversion rates to open surgery were similar: 3.4% in the NPAS group, 5.9% in the minor PAS group, and 9.7% in the major PAS group (P = .113). Estimated blood loss (EBL; P = .961), operative times (OTs; P = .062), complication rates (P = .162), 30-day readmission (P = .691), and 30-day mortality (P = .494) were similar. Of note, 53 patients underwent lysis of adhesions (LOA). On multivariate analysis, EBL >500 mL and LOA significantly influenced conversion to open surgery. EBL >500 mL, age >65 years, conversion to open surgery, and prolonged OT were risk factors for prolonged LOS, whereas adherence to ERPs was a protector. CONCLUSION PAS did not seem to affect the outcomes in RA rectal surgery. Given this finding, the robotic approach may ultimately provide patients with PAS with similar risk to patients without PAS.

Abstract
INTRODUCTION Adverse events from surgical interventions are common. They can occur at various stages of surgical care, and they carry a heavy burden on the different parties involved. While extensive research and efforts have been made to better understand the etiologies of postoperative complications, more research on intraoperative adverse events (iAEs) remains to be done. METHODS In this article, we reviewed the literature looking at iAEs to discuss their risk factors, their implications on surgical care, and the current efforts to mitigate and manage them. RESULTS Risk factors for iAEs are diverse and are dictated by patient-related risk factors, the nature and complexity of the procedures, the surgeon's experience, and the work environment of the operating room. The implications of iAEs vary according to their severity and include increased rates of 30-day postoperative morbidity and mortality, increased length of hospital stay and readmission, increased care cost, and a second victim emotional toll on the operating surgeon. CONCLUSIONS While transparent reporting of iAEs remains a challenge, many efforts are using new measures not only to report iAEs but also to provide better surveillance, prevention, and mitigation strategies to reduce their overall adverse impact.

The incidence and impact of enterotomy during laparoscopic and robotic ventral hernia repair: a nationwide readmissions analysis. Surg Endosc 2023:10.1007/s00464-023-09867-1. [PMID: 37277520 DOI: 10.1007/s00464-023-09867-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 01/04/2023] [Indexed: 06/07/2023]
Abstract
INTRODUCTION Our aim was to define the national incidence of enterotomy (ENT) during minimally invasive ventral hernia repair (MIS-VHR) and evaluate impact on short-term outcomes. METHODS The 2016-2018 Nationwide Readmissions Database was queried using ICD-10 codes for MIS-VHR and enterotomy. All patients had 3-months follow-up. Patients were stratified by elective status; patients without ENT (No-ENT) were compared against ENT patients. RESULTS In total, 30,025 patients underwent LVHR and ENT occurred in 388 (1.3%) patients; 19,188 (63.9%) cases were elective including 244 elective-ENT patients. Incidence was similar between elective versus non-elective cohorts (1.27% vs 1.33%; p = 0.674). Compared to laparoscopy, ENT was more common during robotic procedures (1.2% vs 1.7%; p = 0.004). Comparison of elective-No-ENT vs elective-ENT showed that elective-ENT patients had a longer median LOS (2 vs 5 days; p < 0.001), higher mean hospital cost ($51,656 vs $76,466; p < 0.001), increased rates of mortality (0.3% vs 2.9%; p < 0.001), and higher 3-month readmission (10.1% vs 13.9%; p = 0.048). Non-elective cohort comparison demonstrated non-elective-ENT patients had a longer median LOS (4 vs 7 days; p < 0.001), higher mean hospital cost ($58,379 vs $87,850; p < 0.001), increased rates of mortality (0.7% vs 2.1%;p < 0.001), and higher 3-month readmission (13.6% vs 22.2%; p < 0.001). In multivariable analysis (odds ratio, 95% CI), higher odds of enterotomy were associated with robotic-assisted procedures (1.386, 1.095-1.754; p = 0.007) and older age (1.014, 1.004-1.024; p = 0.006). Lower odds of ENT were associated with BMI > 25 kg/m2 (0.784, 0.624-0.984; p = 0.036) and metropolitan teaching vs metropolitan non-teaching (0.784, 0.622-0.987; p = 0.044). ENT patients (n = 388) were more likely to be readmitted with post-operative infection (1.9% vs 4.1%; p = 0.002) or bowel obstruction (1.0% vs 5.2%;p < 0.001) and more likely to undergo reoperation for intestinal adhesions (0.3% vs 1.0%; p = 0.036). CONCLUSION Inadvertent ENT occurred in 1.3% of MIS-VHRs, had similar rates between elective and urgent cases, but was more common for robotic procedures. ENT patients had a longer LOS, and increased cost and infection, readmission, re-operation and mortality rates.

Predicting long-term risk of reoperations following abdominal and pelvic surgery: a nationwide retrospective cohort study. Int J Surg 2023; 109:1639-1647. [PMID: 37042312 PMCID: PMC10389206 DOI: 10.1097/js9.0000000000000375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 03/24/2023] [Indexed: 04/13/2023]
Abstract
BACKGROUND The risk of reoperations after abdominal and pelvic surgery is multifactorial and difficult to predict. The risk of reoperation is frequently underestimated by surgeons as most reoperations are not related to the initial procedure and diagnosis. During reoperation, adhesiolysis is often required, and patients have an increased risk of complications. Therefore, the aim of this study was to provide an evidence-based prediction model based on the risk of reoperation. MATERIALS AND METHODS A nationwide cohort study was conducted including all patients undergoing an initial abdominal or pelvic operation between 1 June 2009 and 30 June 2011 in Scotland. Nomograms based on multivariable prediction models were constructed for the 2-year and 5-year overall risk of reoperation and risk of reoperation in the same surgical area. Internal cross-validation was applied to evaluate reliability. RESULTS Of the 72 270 patients with an initial abdominal or pelvic surgery, 10 467 (14.5%) underwent reoperation within 5 years postoperatively. Mesh placement, colorectal surgery, diagnosis of inflammatory bowel disease, previous radiotherapy, younger age, open surgical approach, malignancy, and female sex increased the risk of reoperation in all the prediction models. Intra-abdominal infection was also a risk factor for the risk of reoperation overall. The accuracy of the prediction model of risk of reoperation overall and risk for the same area was good for both parameters ( c -statistic=0.72 and 0.72). CONCLUSIONS Risk factors for abdominal reoperation were identified and prediction models displayed as nomograms were constructed to predict the risk of reoperation in the individual patient. The prediction models were robust in internal cross-validation.

Abstract
The cause of all small bowel obstruction in 60-75% of cases is adhesive development. The first and main method for adhesion prevention is undoubtedly the surgical technique, but the prevention of adhesive development is still actual. We aimed to study macroscopic and microscopic peculiarities of the intestine, peritoneum, and scars of the anterolateral abdominal wall. Also, immunological blood changes were observed in rats with the experimental created adhesive disease on the background of azathioprine introduction. The experiment was conducted on 40 rats divided into 2 subgroups: 20 animals as an experimental group (EG1) and 20 as a control group (CG1). Animals from EG received azathioprine (Moshimerampreparaty named by N.A. Semashko, Russia) in a dosage of 1 mg/100g of weight once a day for the first 3 days (starting from the day of surgery). The control group did not receive any drugs. All 40 rats survived the postoperative period. Rats were removed from the experiment on the 7th day after the operation. There were significant statistical differences in most indicators between the experimental and control groups. Phagocytic index (PI) was reduced by 4.55 due to the natural reaction of the rat organism to the surgery. Indicators of EG were a slight decrease in leukocytes and lymphocytes by 0.3 and 0.9, respectively, a moderate decrease in T-lymphocytes by no more than 2.0, and a decrease in phagocytic activity by 5.8. Immunosuppression with azathioprine significantly reduced the frequency and severity of the adhesive process of the abdominal cavity. Used in the recommended dose does not significantly inhibit important indicators of immunity and does not affect wound healing processes.

Abstract
BACKGROUND Intraoperative adverse events (iAEs) are frequent in visceral surgery, but severity and related postoperative outcome are poorly investigated. A novel classification of intraoperative adverse events, ClassIntra, includes surgical and anesthesiologic intraoperative adverse events using 5 severity grades and showed a high criterion and construct validity across all surgical disciplines. ClassIntra was studied for reproducibility in a prespecified group of patients undergoing visceral surgery. METHODS iAEs were recorded in all patients enrolled in the ClassIntra validation study (NCT03009929). Postoperative complications were assessed daily according to the Clavien-Dindo classification. Results of the visceral group were compared with those of the non-visceral group and the full cohort. The risk-adjusted association between most severe intra and postoperative complications was investigated in a multivariable proportional odds model. Second, risk-adjusted association between ClassIntra grade and Comprehensive Complication Index, and postoperative length of stay was investigated. RESULTS In total, 1,270 out of 2,520 patients (50%) underwent visceral surgery. Compared with the nonvisceral group and full cohort, more intraoperative (337/1270 [27%] vs 273/1250 [22%] vs 610/2520 [24%] patients) and postoperative complications (457/1270 [36%] vs 381/1250 [30%] vs 838/2520 [33%] patients) occurred. The risk for a more severe postoperative complication increased with each ClassIntra grade (odds ratio [95% confidence interval] I vs 0 1.10 [0.73 to 1.66], II vs 0 1.69 [1.10 to 2.60], III vs 0 2.31 [1.21 to 4.41], IV vs 0 2.35 [0.69 to 8.06]). Accordingly, CCI and postoperative length of stay increased with each ClassIntra grade in the visceral group, comparable with the nonvisceral and full cohort. CONCLUSION Consistent results for the association of intraoperative adverse events and patient outcomes render ClassIntra a valuable instrument in visceral surgery.

Predictive factors of recurrence for laparoscopic repair of primary and incisional ventral hernias with single mesh from a multicenter study. Sci Rep 2022; 12:4215.

Abstract
Laparoscopic ventral hernia repair (LVHR) is a widely practiced treatment for primary (PH) and incisional (IH) hernias, with acceptable outcomes. Prevention of recurrence is crucial and still highly debated. Purpose of this study was to evaluate predictive factors of recurrence following LVHR with intraperitoneal onlay mesh with a single type of mesh for both PH and IH. A retrospective, multicentre study of data collected from patients who underwent LVHR for PH and IH with an intraperitoneal monofilament polypropylene mesh from January 2014 to December 2018 at 8 referral centers was conducted, and statistical analysis for risk factors of recurrence and post-operative outcomes was performed. A total of 1018 patients were collected, with 665 cases of IH (65.3%) and 353 of PH (34.7%). IH patients were older (p < 0.001), less frequently obese (p = 0.031), at higher ASA class (p < 0.001) and presented more frequently with large, swiss cheese type and border site defects (p < 0.001), compared to PH patients. Operative time and hospital stay were longer for IH (p < 0.001), but intraoperative and early post-operative complications and reinterventions were comparable. IH group presented at major risk of recurrence than PH (6.7% vs 0.9%, p < 0.001) and application of absorbable tacks resulted a significative predictive factor for recurrence increasing the risk by 2.94 (95% CI 1.18–7.31). LVHR with a light-weight polypropylene mesh has low intra- and post-operative complications and is appropriate for both IH and PH. Non absorbable tacks and mixed fixation system seem to be preferable to absorbable tacks alone.

Abstract
OBJECTIVE To assess prevalence of hernia recurrence, surgical site infection (SSI), seroma, serious complications, and mortality after retro-rectus repair. SUMMARY BACKGROUND DATA Ventral abdominal wall hernia is a common problem, tied to increasing frailty and obesity of patients undergoing surgery. For non-complex ventral hernia, retro-rectus (Rives-Stoppa) repair is considered the gold standard treatment. Level-1 evidence confirming this presumed superiority is lacking. METHODS Five databases were searched for studies reporting on retro-rectus repair. Single-armed and comparative randomized and non-randomized studies were included. Outcomes were pooled with mixed-effects, inverse variance or random-effects models. RESULTS Ninety-three studies representing 12440 patients undergoing retro-rectus repair were included. Pooled hernia recurrence was estimated at 3.2% (95%CI: 2.2-4.2%, n = 11049) after minimally 12 months and 4.1%, (95%CI: 2.9-5.5%, n = 3830) after minimally 24 months. Incidences of SSI and seroma were estimated at respectively 5.2% (95%CI: 4.2-6.4%, n = 4891) and 5.5% (95%CI: 4.4-6.8%, n = 3650). Retro-rectus repair was associated with lower recurrence rates compared to onlay repair (OR: 0.27, 95%CI: 0.15-0.51, p < 0.001) and equal recurrence rates compared to intraperitoneal onlay (IPOM) repair (OR: 0.92, 95%CI: 0.75-1.12, p = 0.400). Retro-rectus repair was associated with more SSI than IPOM repair (OR: 1.8, 95%CI: 1.03-3.14, p = 0.038). Minimally invasive retro-rectus repair displayed low rates of recurrence (1.3%, 95%CI: 0.7-2.3%, n = 849) and SSI (1.5%, 95%CI: 0.8-2.8%, n = 982), albeit based on non-randomized studies. CONCLUSIONS Retro-rectus (Rives-Stoppa) repair results in excellent outcomes, superior or similar to other techniques for all outcomes except surgical site infection. The latter rarely occurred, yet less frequently after IPOM repair, which is usually performed by laparoscopy.

Abstract
<br><b>Introduction:</b> Postoperative intra-abdominal adhesions are a clinical condition that may develop after any abdominal surgery and constitute the leading cause of mechanical small bowel obstructions.</br>
<br><b>Aim:</b> This study investigates factors which influence the formation of postoperative adhesion and evaluates the efficiency of applying minimally invasive surgical techniques in reducing adhesion.</br>
<br><b>Material and methods:</b> Patients who underwent surgery to diagnose obstructive ileus in our clinic between January 2015 and January 2020 were analyzed retrospectively. Demographic data of the patients, operation details time between the operations and history of hospitalizations, postoperative mortality and morbidity, as well as the severity of complications were recorded. The patients included in the study were divided into groups according to the surgical technique applied in the first operation (laparoscopy/ laparotomy), the abdominal incision line (upper/lower/total), and the etiology of the primarily operated lesion (benign/malignant).</br>
<br><b>Results:</b> One hundred eighteen (118) patients were included in the study. The mean age of patients was 61.2 ± 10.8 (39–82) years. Age, ileus history, time to the onset of ileus, length of hospital stay and the number of complications were shorter in the laparoscopy group as compared to the laparotomy group and the difference was found to be statistically significant. In addition, when patients were categorized according to the abdominal incision line, fewer hospitalizations and more frequent postoperative complications due to ileus were observed in the sub-umbilical incision group (p < 0.05).</br>
<br><b>Conclusions:</b> Postoperative adhesion formation is currently one of the clinical conditions which pose a challenge to both the patient and the clinician due to its incidence and recurrence. However, adhesion formation can be reduced by applying minimally invasive surgical methods, especially laparoscopic surgery and precise maneuvers during surgery.</br>

Abstract
BACKGROUND Surgical management of patients with ventral abdominal wall defects, especially complex abdominal wall defects, remains a challenging problem for abdominal wall reconstructive surgeons. Effective surgical treatment requires appropriate preoperative assessment, surgical planning, and correct operative procedure in order to improve postoperative clinical outcomes and minimize complications. Although substantial advances have been made in surgical techniques and prosthetic technologies, there is still insufficient high-level evidence favoring a specific technique. Broad variability in existing practice patterns, including clinical pre-operative evaluation, surgical techniques and surgical procedure selection, are still common. DATA SOURCES With the purpose of providing a best practice algorithm, a comprehensive search was conducted in Medline and PubMed. Sixty-four surgeons considered as experts on abdominal wall defect repair and reconstruction in China were solicited to develop a Chinese consensus and give recommendations to help surgeons standardize their techniques and improve clinical results. CONCLUSIONS This consensus serves as a starting point to provide recommendations for adult ventral abdominal wall repair and reconstruction in China and may help build opportunities for international cooperation to refine AWR practice.

Abstract
Background: Surgical site infection (SSI) is a well-recognized and potentially catastrophic complication of abdominal wall reconstruction (AWR). The authors present a review of the literature surrounding SSI in AWR, exploring prevention and treatment strategies as well as risk factors. Methods: A comprehensive review of the current literature was undertaken. Evidence was reviewed and summarized with particular focus on prevention and treatment strategies available to hernia surgeons. Results: Patient risk factors for SSI are well described in the literature and include obesity, smoking, and other comorbidities. Contaminated hernias and cases involving enterocutaneous fistulae are also at higher risk of SSI. Surgical decisions such as type of mesh, plane of mesh placement, and fascial release may all contribute to SSI risk. To treat established mesh infection, conservative management with antibiotic agents and negative pressure therapy is a reasonable option in some cases. Removal of prosthesis appears to provide favorable results, however, repeat surgery can be problematic Conclusions: Surgical site infection remains an important pathology in the world of AWR. Surgeons have a wealth of tools in their arsenal to prevent and treat SSI and should be aware of the emerging evidence in the fast-moving specialty of hernia surgery. Complex cases should be handled by surgeons and centers with expertise in treating such patients.

Abstract
Surgery is performed to treat various diseases. During the process, the surgical site is healed through self-healing after surgery. Post-operative or tissue adhesion caused by unnecessary contact with the surgical site occurs during the normal healing process. In addition, it has been frequently found in patients who have undergone surgery, and severe adhesion can cause chronic pain and various complications. Therefore, anti-adhesion barriers have been developed using multiple biomaterials to prevent post-operative adhesion. Typically, anti-adhesion barriers are manufactured and sold in numerous forms, such as gels, solutions, and films, but there are no products that can completely prevent post-operative adhesion. These products are generally applied over the surgical site to physically block adhesion to other sites (organs). Many studies have recently been conducted to increase the anti-adhesion effects through various strategies. This article reviews recent research trends in anti-adhesion barriers.

Abstract
BACKGROUND Ventral hernia repair is typically performed via a transabdominal approach and the peritoneal cavity is opened and explored. Totally extraperitoneal ventral hernia repair (TEVHR) facilitates dissection of the hernia sac without entering the peritoneal cavity. This study evaluates our experience of TEVHR, addressing technique, decision-making, and outcomes. METHODS This is an IRB-approved retrospective review of open TEVHR performed between January 2012 and December 2016. Medical records were reviewed for patient demographics, operative details, postoperative outcomes, hospital readmissions, and reoperations. RESULTS One hundred sixty-six patients underwent TEVHR (84 males, 82 females) with a mean BMI range of 30-39. Eighty-six percent of patients underwent repair for primary or first-time recurrent hernia, and 89% CDC wound class I. Median hernia defect size was 135 cm2. Hernia repair techniques included Rives-Stoppa (34%) or transversus abdominis release (57%). Median operative time was 175 min, median blood loss 100 mL, and median length of stay 4 days. There were no unplanned bowel resections or enterotomies. Four cases required intraperitoneal entry to explant prior mesh. Wound complication rate was 27%: 9% seroma drainage, 18% superficial surgical site infection (SSI), and 2% deep space SSI. Five patients (3%) required reoperation for wound or mesh complications. Over the study, four patients were hospitalized for postoperative small bowel obstruction and managed non-operatively. Of the 166 patients, 96%, 54%, and 44% were seen at 3-month, 6-month, and 12-month follow-ups, respectively. Recurrences were observed in 2% of patients at 12-month follow-up. One patient developed an enterocutaneous fistula 28 months postoperatively. CONCLUSIONS TEVHR is a safe alternative to traditional transabdominal approaches to ventral hernia repair. The extraperitoneal dissection facilitates hernia repair, avoiding peritoneal entry and adhesiolysis, resulting in decreased operative times. In our study, there was low risk for postoperative bowel obstruction and enterotomy. Future prospective studies with long-term follow-up are required to draw definitive conclusions.

Abstract
PURPOSE Laparoscopic intraperitoneal onlay mesh in hernia repair can result in adhesions leading to intestinal obstruction and fistulation. The aim of this systematic review is to compare the effects of mesh coatings reducing the tissue-to-mesh adhesion in animal studies. METHODS Pubmed and Embase were systematically searched. Animal experiments comparing intraperitoneally placed meshes with coatings were eligible for inclusion. Only studies with comparable follow-up, measurements, and species were included for data pooling and subsequent meta-analysis. RESULTS A total of 131 articles met inclusion criteria, with four studies integrated into one comparison and five studies integrated into another comparison. Compared to uncoated polypropylene (PP) mesh, PP mesh coated with hyaluronic acid/carboxymethyl cellulose (HA/CMC) showed significantly reduced adhesion formation at follow-up of 4 weeks measured with adhesion score of extent (random effects model, mean difference,- 0.96, 95% CI - 1.32 to - 0.61, P < 0.001, I2 = 23%; fixed effects model, mean difference,- 0.94, 95% CI - 1.25 to - 0.63, P < 0.001, I2 = 23%). Compared to PP mesh, polyester mesh coated with collagen (PC mesh) showed no significant difference at follow-up of 4 weeks regarding percentage of adhesion-area on a mesh, using random effects model (mean difference - 11.69, 95% CI - 44.14 to 20.76, P = 0.48, I2 = 92%). However, this result differed using fixed effects model (mean difference - 25.55, 95% CI - 33.70 to - 7.40, P < 0.001, I2 = 92%). CONCLUSION HA/CMC coating reduces adhesion formation to PP mesh effectively at a follow-up of 4 weeks, while the anti-adhesive properties of PC mesh are inclusive comparing all study data.

Pooled data analysis of primary ventral (PVH) and incisional hernia (IH) repair is no more acceptable: results of a systematic review and metanalysis of current literature. Hernia 2019; 23:831-845.

Abstract
PURPOSE Primary (PVHs) and incisional (IHs) ventral hernias represent a common indication for surgery. Nevertheless, most of the papers presented in literature analyze both types of defect together, thus potentially introducing a bias in the results of interpretation. The purpose of this systematic review and meta-analysis is to highlight the differences between these two entities. METHODS Methods MEDLINE, Scopus, and Web of Science databases were reviewed to identify studies evaluating the outcomes of both open and laparoscopic repair with mesh of PVHs vs IHs. Search was restricted to English language literature. Risk of bias was assessed with MINORS score. Primary outcome was recurrence, and secondary outcomes were baseline characteristics and intraoperative and postoperative data. Fixed effects model was used unless significant heterogeneity, assessed with the Higgins I square (I2), was encountered. RESULTS The search resulted in 783 hits, after screening; 11 retrospective trials were selected including 38,727 patients. Mean MINORS of included trials was 15.2 (range 5-21). The estimated pooled proportion difference for recurrence was - 0.09 (- 0.11; - 0.07) between the two groups in favor of the PVH group. On metanalysis, PVHs were smaller in area and diameters, affected younger and less comorbid patients, and were more frequently singular; the operative time and length of stay was quicker. Other complications did not differ significantly. CONCLUSION Our paper supports the hypothesis that PVH and IH are different conditions with the latter being more challenging to treat. Accordingly, EHS classifications should be adopted systematically as well as pooling data analysis should be no longer performed in clinical trials.

Abstract
BACKGROUND The aim of the study was to evaluate the outcomes of 100 consecutive patients undergoing reconstructive operation for enteric and colonic fistulas. These fistulas cause dramatic morbidity and profoundly diminish quality of life. Fistula takedown has been associated with high rates of recurrence. METHODS Consecutive patients undergoing definitive fistula reconstruction by a single surgeon were reviewed retrospectively. Major adverse outcomes included bowel leak, fistula recurrence, death, total parenteral nutrition dependence, and incidence of new stomas. RESULTS Among the 100 patients, median follow-up was 2.7 years. A total of 11 patients had postoperative leaks that evolved to 5 fistula recurrences. Of these patients 3 underwent successful secondary or tertiary takedown. The 30-day mortality rate was 1%, and the combined postoperative and fistula-related mortality rate at follow-up was 3%. New postoperative total parenteral nutrition dependence occurred in 2 patients (2%), and 9 (9%) had placement of a new stoma. Leaks were more frequent for patients who had a history of open abdomen than for patients who did not. CONCLUSIONS With minimal patient selection and a methodic approach to evaluation and management, we achieved a 96% fistula-free survival rate. Few patients acquired new total parenteral nutrition dependence or a new stoma. These results compare favorably with outcomes published elsewhere.

Abstract
Postoperative adhesion is a common complication and preventing adhesions during or immediately after operation is particularly important. The application of solid barrier materials represents the most successful clinical strategy to prevent postoperative adhesion. However, a simple physical barrier effect might be insufficient in preventing adhesion satisfactorily. Multilayered structures can be designed with an outer layer as the barrier and an inner layer to respond to relative drug release. In this article, bilayer film composed of a PLGA/PLCA casting layer as barrier and PLGA/PDPA electrospinning layer to respond to the release of anti-fibrosis drug l-Phe was designed and synthesized. The adhesion prevention effect of the above PLGA/PLCA/PDPA bilayer film was examined and compared with single PLGA/PLCA casting film and single PLGA/PDPA electrospinning film by applying rabbit sidewall defect-cecum abrasion model. As demonstrated by histological observation and immunohistochemical analysis, the bilayer film was the most effective of the three films in postoperative adhesion prevention in terms of both physical barrier effect and anti-fibrosis effect of the PDPA macromolecular prodrug. Besides anti-fibrosis effect, PDPA could also suppress excess proliferation of vascular endothelial cells and microvessel caused by long-term stimulation of implantation materials to the surrounding tissues. © 2018 Wiley Periodicals, Inc.

Abstract
BACKGROUND This study aimed to define the incidence and risk factors of postoperative morbidity and mortality after pouch excision (PE). METHODS ACS-NSQIP database was queried for patients who underwent PE between 2005 and 2015. Main outcome measures were 30-day mortality, major morbidity, overall surgical site infections (SSI), reoperation, and length of stay (LOS). Risk factors associated with these outcomes were assessed using multivariate logistic or quantile regression. RESULTS Three hundred eighty-one patients underwent PE (mean age 47.7(±15.3) years; 51.7% female). Mean body mass index (BMI) was 24.6(±5.7) kg/m2, 55.4% were ASA class 1-2 and 18.4% were immunosuppressed. Mean operative time was 252(±112.7) min, 98% were elective cases, and median LOS was 7(5-11) days. Twenty-eight percent experienced major morbidity, including SSIs (21.5% overall, 9.2% superficial, 3.7% deep, 10.3% organ space), sepsis (9.5%), urinary tract infection (5.8%), and postoperative pneumonia (2.4%). The observed venous thromboembolism rate was low, with 0.5 and 0.8% of patients suffering pulmonary embolism and deep vein thrombosis, respectively; 5.5% required reoperation. Postoperative mortality was 0.8%. On multivariate logistic regression, smoking (OR 3.03 [95% CI 1.56, 5.88]) and operative time (OR 1.003 [95% CI 1.0003, 1.0005) were associated with increased odds of major morbidity. Smoking (OR 3.29 [95% CI 1.65, 6.54]) and operative time (OR 1.002 [95% CI 1.000, 1.004]) were independent risk factors for overall SSI. LOS was significantly increased in patients with major morbidity (3.29 days [95% CI 1.60, 4.99]) and increased operative time (0.013 days [95% CI 0.007, 0.018]). CONCLUSIONS PE is an operation with significant risk of morbidity. However, mortality was low in the present cohort of patients. Patients who were smokers and had longer operative time had increased risk of overall infectious complications and major morbidity. Furthermore, major morbidity and operative time were associated with increased hospital length of stay following PE.

Abstract
To date, there is no shared consensus on a definition of a complex abdominal wall in elective surgery and in the emergency, on indications, technical details, complications, and follow-up. The purpose of the conference was to lay the foundations for a homogeneous approach to the complex abdominal wall with the primary intent being to attain the following objectives: (1) to develop evidence-based recommendations to define “complex abdominal wall”; (2) indications in emergency and in elective cases; (3) management of “complex abdominal wall”; (4) techniques for temporary abdominal closure. The decompressive laparostomy should be considered in a case of abdominal compartment syndrome in patients with critical conditions or after the failure of a medical treatment or less invasive methods. In the second one, beyond different mechanism, patients with surgical emergency diseases might reach the same pathophysiological end point of trauma patients where a preventive “open abdomen” might be indicated (a temporary abdominal closure: in the case of a non-infected field, the Wittmann patch and the NPWT had the best outcome followed by meshes; in the case of an infected field, NPWT techniques seem to be the preferred). The second priority is to create optimal both general as local conditions for healing: the right antimicrobial management, feeding—preferably by the enteral route—and managing correctly the open abdomen wall. The use of a mesh appears to be—if and when possible—the gold standard. There is a lot of enthusiasm about biological meshes. But the actual evidence supports their use only in contaminated or potentially contaminated fields but above all, to reduce the higher rate of recurrences, the wall anatomy and function should be restored in the midline, with or without component separation technique. On the other site has not to be neglected that the use of monofilament and macroporous non-absorbable meshes, in extraperitoneal position, in the setting of the complex abdomen with contamination, seems to have a cost effective role too. The idea of this consensus conference was mainly to try to bring order in the so copious, but not always so “evident” literature utilizing and exchanging the expertise of different specialists.

Abstract
PURPOSE The seroma rate following laparoscopic incisional ventral hernia repair (LIVHR) is up to 78%. LIVHR is connected to a relatively rare but dangerous complication, enterotomy, especially in cases with complex adhesiolysis. Closure of the fascial defect and extirpation of the hernia sack may reduce the risk of seromas and other hernia-site events. Our aim was to evaluate whether hybrid operation has a lower rate of the early complications compared to the standard LIVHR. METHODS This is a multicenter randomized-controlled clinical trial. From November 2012 to May 2015, 193 patients undergoing LIVHR for primary incisional hernia with fascial defect size from 2 to 7 cm were recruited in 11 Finnish hospitals. Patients were randomized to either a laparoscopic (LG) or to a hybrid (HG) repair group. The outcome measures were the incidence of clinically and radiologically detected seromas and their extent 1 month after surgery, peri/postoperative complications, and pain. RESULTS Bulging was observed by clinical evaluation in 46 (49%) LG patients and in 27 (31%) HG patients (p = 0.022). Ultrasound examination detected more seromas (67 vs. 45%, p = 0.004) and larger seromas (471 vs. 112 cm3, p = 0.025) after LG than after HG. In LG, there were 5 (5.3%) enterotomies compared to 1 (1.1%) in HG (p = 0.108). Adhesiolysis was more complex in LG than in HG (26.6 vs. 13.3%, p = 0.028). Patients in HG had higher pain scores on the first postoperative day (VAS 5.2 vs. 4.3, p = 0.019). CONCLUSION Closure of the fascial defect and extirpation of the hernia sack reduce seroma formation. In hybrid operations, the risk of enterotomy seems to be lower than in laparoscopic repair, which should be considered in cases with complex adhesions. CLINICAL TRIAL NUMBER NCT02542085.

Abstract
BACKGROUND Patients undergoing ventral hernia repair (VHR) are at risk of an inadvertent enterotomy during surgery. Inadvertent enterotomies potentially contaminate the surgical field presenting a management dilemma for the surgeon. The aim of our study was to define the incidence and risk factors for a recognized inadvertent enterotomy and determine its impact on short-term outcomes after ventral hernia repair. METHODS Using a nationwide hernia registry, the Americas Hernia Society Quality Collaborative, we reviewed all ventral hernia repair performed between 2013 and 2017. Patients were assessed for full-thickness inadvertent enterotomies at the time of surgery. Patients with inadvertent enterotomies and without enterotomies were compared to assess differences in 30-day outcomes, using regression modeling. RESULTS A total of 5,916 patients were included. The incidence of inadvertent enterotomy was 1.9%, with no difference between open and laparoscopic approaches. Inadvertent enterotomies did not increase surgical site occurrences but there were more surgical site infections (OR: 2.20 [95% CI: 1.24-3.90], P = .007). Patients were less likely to receive mesh if there was an enterotomy. Inadvertent enterotomies led to higher rates of reoperations, readmission, enterocutaneous fistulas, and mortality. CONCLUSION Inadvertent enterotomies are more common in complex cases of ventral hernia repair and have an overall incidence of 1.9%. These patients are at increased risk of surgical site infections, reoperations, readmission, and mortality. Although definitive hernia repair with mesh can be safely performed, surgeons should consider multiple factors, including type of mesh and location of mesh in the abdominal wall, before proceeding with definitive repair in any case of an enterotomy.

Abstract
Our knowledge of the types of intraoperative patient safety events, their harm to patients, and relationship to postoperative complications is sparse. This study examined intraoperative medical errors (iMEs) and intraoperative adverse events (iAEs) voluntarily reported by providers using two programs at our hospital: surgical debriefing and incident reporting. Among the 3020 surgical procedures assessed, 142 iMEs and 103 iAEs were reported, yielding an overall rate of 8%. Of these events, 135 (55%) were obtained from incident reporting and 110 (45%) from surgical debriefing. The overall association between intraoperative events (iMEs and iAEs) and 30-day postoperative morbidity was significant (adjusted odds ratio = 1.08 with 95% confidence interval (CI) of (1.03, 1.13). This association was stronger when we included only the iAEs (1.47, 95% CI (1.35, 1.58)). Our findings suggest that hospitals should consider using both programs to obtain a more complete picture of intraoperative patient safety and to reduce postoperative morbidity.

Abstract
Postoperative adhesions remain one of the more challenging issues in surgical practice. Although peritoneal adhesions occur after every abdominal operation, the density, time interval to develop symptoms, and clinical presentation are highly variable with no predictable patterns. Numerous studies have investigated the pathophysiology of postoperative adhesions both in vitro and in vivo. Factors such as type and location of adhesions, as well as timing and recurrence of adhesive obstruction remain unpredictable and poorly understood. Although the majority of postoperative adhesions are clinically silent, the consequences of adhesion formation can represent a lifelong problem including chronic abdominal pain, recurrent intestinal obstruction requiring multiple hospitalizations, and infertility. Moreover, adhesive disease can become a chronic medical condition with significant morbidity and no effective therapy. Despite recent advances in surgical techniques, there is no reliable strategy to manage postoperative adhesions. We herein review the pathophysiology and clinical significance of postoperative adhesions while highlighting current techniques of prevention and treatment.

Detection and potential consequences of intraoperative adverse events: A pilot study in the veterans health administration. Am J Surg 2017; 214:786-791.

Abstract
Surgical quality improvement efforts have focused on tracking and reducing postoperative mortality and morbidity. However, the prevalence of intraoperative adverse events (IAEs) and their association with postoperative surgical outcomes has been poorly studied. In this study, we detected IAEs using both retrospective chart review and prospective provider reporting. We then examined the association of IAEs with postoperative outcomes. The overall IAE detection rate per case was 0.7 and 0.07 (P < 0.0001) based on chart review and provider reporting, respectively. Types of IAEs varied between detection methods. Provider-reported IAEs were more serious, i.e., had a stronger association with 30-day postoperative complications than chart-identified IAEs (risk-adjusted odds ratios were 1.52 vs 1.02, respectively, both p < 0.0001). Our findings suggest that IAEs can be detected using either retrospective chart review or prospective provider reporting. However, provider reporting appears more likely to detect serious (albeit infrequent) IAEs compared to chart review.

Abstract
BACKGROUND Bridging of the hernia defect in laparoscopic repair (sIPOM) technique does not fully restore the abdominal wall function. Closure of hernia defect in IPOM-plus technique leads to the restoration of abdominal wall function and improved long-term treatment outcomes. Against the expectations, the studies confirm the formation of intraabdominal adhesions to the mesh. Regardless of the above, the search of the proper technique for mesh implantation and fixation is still ongoing. There have also been attempts to identify groups of patients who may still benefit from IPOM procedure. MATERIALS AND METHODS Patients with midline abdominal wall hernias up to 10 cm wide were enrolled in the study except for subxiphoid and suprapubic hernias. Between 2011 and 2014 we performed 82 hernia repairs using the laparoscopic technique with Physiomesh. Patients were divided into sIPOM and IPOM-plus groups. The study included 44M and 38F patients aged 27-84 years. After 12-months and again in August 2015 a survey was posted to all patients with questions regarding potential recurrence. RESULTS After 12 months, eight patients (20 %) in sIPOM group reported subjectively perceived recurrence and none in IPOM-plus group (p = 0.002). Six patients (14.3 %) in sIPOM group reported suspected recurrence, as compared to three patients (7.1 %) in IPOM-plus group (p = 0.13). These patients were invited for a follow-up physical examination and sonography. Eventually, four cases of hernia recurrence were confirmed in sIPOM group (10 %) and none in IPOM-plus group (p = 0.018). Other patients presented with mesh bulging. CONCLUSIONS Laparoscopic ventral hernia repair is generally safe and is associated with the low recurrence rate. Closure of fascial defects before mesh insertion offers better treatment outcomes. Non-closure of fascial defects with only bridging of the hernia defect (sIPOM) causes more frequent recurrence and bulging. As a result, patient satisfaction with treatment is lower, and they are concerned about hernia recurrence.

Abstract
BACKGROUND Early identification of serious adverse events following ventral hernia repair (VHR) could result in improved patient outcomes. Establishment of clinical markers that correlate with serious adverse events following VHR would help facilitate a more timely diagnosis of such events. We investigated the clinical utility of postoperative tachycardia to predict serious adverse events in patients undergoing VHR. METHODS Consecutive patients undergoing VHR at the Cleveland Clinic Comprehensive Hernia Center from September 2013 through June 2015 were identified within the Americas Hernia Society Quality Collaborative database. Tachycardia was classified according to frequency and duration. Sustained tachycardia was defined as >8 consecutive hours of tachycardia on any postoperative day. Serious adverse events were defined as cardiac events, venous thromboembolism, infection, bleeding, and anastomotic leak or missed enterotomy. Association between tachycardia class and serious adverse events was investigated using the Pearson χ(2) test. RESULTS A total of 377 patients underwent VHR during the study period. A total of 119 (31.6%) patients experienced at least 1 episode of tachycardia. There were 26 (6.9%) patients with a serious adverse event. Tachycardia was present in 21 (80.7%) of these patients. Sustained tachycardia had a significant association with serious adverse events (P = .007). The presence of postoperative tachycardia was associated with the occurrence of a serious adverse event, having a positive likelihood ratio of 2.9 (95% confidence interval 2.2-3.7). CONCLUSION Postoperative tachycardia is common following VHR. Nevertheless, sustained tachycardia is associated with a significant risk for serious postoperative adverse events and mandates further investigation.

Abstract
Introduction: Intraabdominal adhesions that develop because of prior abdominal or pelvic surgery may cause problems during surgery. Complications can include difficult intraabdominal entry; injury to the urinary bladder, uterus or small intestine; longer operation times, and increased blood loss. The goal of the present study was to evaluate the association between abdominal striae gravidarum and intraabdominal adhesions in the preoperative period in pregnant women with a history of cesarean section. Materials and Methods: The study included 247 pregnant women at ≥ 37 weeks of gestation admitted to the labor unit for delivery; all had undergone at least one previous cesarean section. Abdominal striae were assessed preoperatively using the Davey scoring system; the severity and intensity of adhesions were subsequently evaluated intraoperatively according to the modified Nair scoring system. Results: No striae were seen in 104 pregnant women; 41 had mild striae and 102 had severe striae. Overall, 113 cases had no adhesions (grade 0), 106 had grade 1-2 adhesions, and 28 had grade 3-4 adhesions. Among patients with grade 0 adhesions, 34 (13.7 %) had no striae, while 79 (31.9 %) had mild-to-severe striae (p < 0.001; sensitivity 55 %; specificity 67 %; positive predictive value 69 %; negative predictive value 52 %). Among women with grade 1-2 adhesions, 48 (19.4 %) had no striae, while 58 (23.4 %) had mild-to-severe striae. Finally, among women with grade 3-4 adhesions, 22 (8.9 %) had no striae, while 6 (2.4 %) had mild-to-severe striae (p < 0.001). A p-value < 0.05 was taken to indicate statistical significance. Conclusions: The abdominal adhesion score dropped as the abdominal striae gravidarum score rose during the preoperative period. Addition of this useful, easy-to-apply, inexpensive, adjunctive, observational, abdominal scoring method to the obstetrical work-up can provide important clues about the intraabdominal adhesion status of pregnant women scheduled for cesarean delivery because of previous cesarean section.

Abstract
BACKGROUND The incidence rates for adenocarcinoma of the esophagus are increasing while the prognosis has only improved slightly. There is no apparent benefit in short- and long-term survival after different surgical strategies, but surgery is associated with significant morbidity. The goal of this study is to prospectively assess the quality of life and hospital costs after esophageal resections depending on the development of complications. METHODS Prospective data was collected from 47 patients undergoing an esophageal resection for esophageal cancer participating in the prospective LAParotomy or LAParoscopy and Adhesions (LAPAD) study (clinicaltrials.gov registration number: NCT01236625). A comparison was made between patients who developed major complications and minor or no complications regarding quality of life and hospital costs. RESULTS Thirteen patients developed major complications while 34 patients developed only minor or no complications. Patients with major complications had a mean hospital cost of $16,369 vs $12,409 for patients without or with minor complications. We found no difference in quality of life between the two groups 6 months after surgery. CONCLUSIONS In our cohort, major complications did not seem to have a detrimental effect on postoperative quality of life 6 months after surgery but they increased costs associated with esophageal resection.

Abstract
Bowel injury (BI) is a complication of open and laparoscopic abdominal surgery associated with increased morbidity and mortality. If BI is missed at the time it occurs, it can have devastating consequences. Electrosurgery is used extensively in laparoscopic surgery and can cause thermal injuries that are harder to detect than mechanical injuries and may evolve over time. The medical literature of the past 10 years was searched for large series and compilation studies reporting overall incidence of and mortality from BI in laparoscopy, and the results of seven relevant articles, which included over 300,000 procedures, were analyzed and tabulated. The literature was then reviewed for additional information about the specific incidence and outcome of missed BI and the role of electrosurgical thermal sources in causing BI. BI is underreported, frequently missed at surgery, and results in significant morbidity and mortality that can be ground for malpractice claims against the surgeon. Thermal injury from electrosurgical instruments may be involved in a number of injuries in laparoscopic surgery. Nearly undetectable partial-thickness thermal injury may play a role in the atypical and delayed presentation of some cases of BI.

Abstract
Small-intestine adhesiolysis can be very time consuming and may be associated with bowel wall damage. The risk for injuries to the small or large bowel resulting in increased morbidity and costs is considerable. Both efficient and gentle dissection of adhesions is important in order to avoid intraoperative perforation or, worse, postoperative intestinal leaks. We present a technique using drops of body-warm isotonic saline solution to create an edematous swelling of the adhesions. This procedure not only protects the bowel from cooling and drying, but also simplifies the dissection and, thus, lowers the risk of intestinal lesions.

Abstract
PURPOSE Adhesiolysis at repeat surgery induces adhesion reformation which seems more virulent than development of de novo adhesions. We studied the effect of a new ultrapure alginate gel on adhesion reformation. METHODS In 46 male Wistar rats, adhesion formation was induced using the cecal abrasion and peritoneal sidewall excision procedure. Two weeks later, a second laparotomy was performed, adhesions were graded, and surgical adhesiolysis was performed. The animals were then allocated to one of two equal groups, a control group without further intervention and a group receiving 1-ml ultrapure alginate gel to the two opposing and damaged surfaces. Two weeks after the second surgery, rats were sacrificed. Primary endpoint was the incidence of adhesion reformation at areas of injury. Secondary endpoints were adhesion scores, extent of adhesions, and tissue histology. RESULTS Ultrapure alginate gel significantly (p = 0.046) reduced the incidence of adhesion reformation from 100 % in controls to 78 % in experimental rats. Both the adhesion score (p = 0.009) and the extent of adhesions (p = 0.001) were significantly lower in the alginate group. Tissue healing histology was similar in both groups. CONCLUSION Ultrapure alginate gel reduces adhesion reformation following adhesiolysis.

Abstract
BACKGROUND We sought to assess the independent effect of concomitant adhesions (CAs) on patient outcome in abdominal surgery. MATERIALS AND METHODS Using the American College of Surgeons National Surgical Quality Improvement Program data, we created a uniform data set of all gastrectomies, enterectomies, hepatectomies, and pancreatectomies performed between 2007 and 2012 at our tertiary academic center. American College of Surgeons National Surgical Quality Improvement Program data were supplemented with additional variables (e.g., procedure complexity-relative value unit). The presence of CAs was detected using the Current Procedural Terminology codes for adhesiolysis (44005, 44180, 50715, 58660, and 58740). Cases where adhesiolysis was the primary procedure (e.g., bowel obstruction) were excluded. Multivariable logistic regression analyses were performed to assess the independent effect of CAs on 30-d morbidity and mortality, while controlling for age, comorbidities and the type/complexity/approach/emergency nature of surgery. RESULTS Adhesiolysis was performed in 875 of 5940 operations (14.7%). Operations with CAs were longer (median duration 3.2 versus 2.7 h, P < 0.001), more complex (median relative value unit 37.5 versus 33.4, P < 0.001), performed in sicker patients (American Society for Anesthesiologists class ≥3 in 49.9% versus 41.2%, P < 0.001), and harbored higher risk for inadvertent enterotomies (3.0% versus 0.9%, P < 0.001). In multivariable analyses, CAs independently predicted higher morbidity (adjusted odds ratio [OR], 1.35; 95% confidence interval, 1.13-1.61, P = 0.001). Specifically, CAs independently correlated with superficial and deep or organ-space surgical site infections (OR = 1.42 (1.02-1.86), P = 0.036; OR = 1.47 (1.09-1.99), P = 0.013, respectively), and prolonged postoperative hospital stay (≥7 d, OR = 1.34 [1.11-1.61], P = 0.002). No difference in 30-d mortality was detected. CONCLUSIONS CAs significantly increase morbidity in abdominal surgery. Risk adjusting for the presence of adhesions is crucial in any efforts aimed at quality assessment and/or benchmarking of abdominal surgery.

Abstract
BACKGROUND Inadvertent bowel injury during adhesiolysis is a major cause of increased morbidity and mortality following abdominal surgery. Identification of risk factors predicting this complication would guide preoperative counselling and surgical decision-making. The aim of this study was to identify predictive preoperative factors for inadvertent bowel injury occurring during adhesiolysis. METHODS All patients undergoing elective abdominal surgery between June 2008 and June 2010 were evaluated prospectively as part of the LAPAD study. Data on adhesiolysis and inadvertent organ injury were gathered by direct observation during operation. Univariable logistic regression was used to investigate factors that increased the risk of inadvertent bowel injury. Independent predictors of bowel injury were identified using multivariable logistic regression and used to create a clinical nomogram. RESULTS Of 715 patients eligible for analysis, 48 (6.7 per cent) had inadvertent bowel injuries. In 42 patients the defect was detected during operation and in nine at a later time (3 patients had both). Bowel resection was required for almost two-thirds of the enterotomies. The number of previous laparotomies, anatomical site of the operation, presence of bowel fistula and laparotomy via a pre-existing median scar were independent predictors of bowel injury. A clinical scoring system was constructed using a nomogram incorporating these risk factors; this had a predictive discrimination, measured as the area under the receiver operating characteristic curve, of 0.85. CONCLUSION A nomogram based on four independent factors predicted the risk of inadvertent bowel injury. REGISTRATION NUMBER NCT01236625 (http://www.clinicaltrials.gov).

Abstract
AIM Our aim was to evaluate the incidence and type of severe complications in adult primary and incisional ventral hernia surgery reported to the National Patient Insurance Centre in Finland during 2003-2010. MATERIAL AND METHODS The Finnish National Patient Insurance Centre covers the whole country and handles financial compensation for patients' injuries without proof of malpractice. All the claims concerning ventral hernioplasties in the Centre between the years 2003 and 2010 were retrospectively analyzed. The annual numbers of primary and incisional ventral hernioplasties in Finland were obtained from the National Hospital Discharge Register. RESULTS During the study years, 25,738 ventral hernia operations were performed and 127 claims from the whole country were reported to the Patient Insurance Centre. Overall rate of claims was 4.9/1000 hernia procedures. For primary hernias, 16,243 ventral hernioplasties (817 laparoscopic, 15,426 open) were performed and 41 complications were reported. The most common complication was infection (n = 28, 68%) followed by pain and hernia recurrence (n = 6, 15% in both), large hematoma (7%), bowel lesion (5%), urological injuries (2%), or severe bleeding (2%). In incisional hernioplasties, the rate of claims was 9.1/1000 operations (9495 operations, 86 claims). The most common complication reported was infection (n = 42, 49%) followed by hernia recurrence in 25 cases (29%) and bowel lesion in 24 cases (28%). Major complications (n = 15, 17%) consisted mainly of bowel lesions in laparoscopic operations. There was significantly more claims after laparoscopic than open hernioplasties (p = 0.001). CONCLUSIONS The claims for financial compensation for injuries related to primary and incisional hernioplasties are quite uncommon. Major complications, though comparatively rare, are significantly more common after laparoscopic operations.

Abstract
BACKGROUND Little evidence exists regarding the characteristics of intraoperative adverse events (iAEs). METHODS Administrative data, the American College of Surgeons - National Surgical Quality Improvement Project, and systematic review of operative reports were used to confirm iAEs in abdominal surgery patients. Standard American College of Surgeons - National Surgical Quality Improvement Project data were supplemented with variables including injury type/organ, phase of operation, adhesions, repair type, and intraoperative consultations. RESULTS Two hundred twenty-seven iAEs (187 patients) were confirmed in 9,292 patients. Most common injuries were enterotomies during intestinal surgery (68%) and vessel injuries during hepatopancreaticobiliary surgery (61%); 108 iAEs (48%) specifically occurred during adhesiolysis. A third of the iAEs required organ/tissue resection or complex reconstruction. Because of iAEs, 20 intraoperative consults (11%) were requested and 9 of the 66 (16%) laparoscopic cases were converted to open. Thirty-day mortality and morbidity were 6% and 58%, respectively. The complications included perioperative transfusions (36%), surgical site infection (19%), systemic sepsis (13%), and failure to wean off the ventilator (12%). CONCLUSIONS iAEs commonly occur in reoperative cases requiring lysis of adhesions and possibly lead to increased patient morbidity. Understanding iAEs is essential to prevent their occurrence and mitigate their adverse effects.

Abstract
BACKGROUND Formation of adhesions after peritoneal surgery results in high morbidity. Barriers to prevent adhesion are seldom applied, despite their ability to reduce the severity of adhesion formation. We evaluated the benefits and harms of four adhesion barriers that have been approved for clinical use. METHODS In this systematic review and meta-analysis, we searched PubMed, CENTRAL, and Embase for randomised clinical trials assessing use of oxidised regenerated cellulose, hyaluronate carboxymethylcellulose, icodextrin, or polyethylene glycol in abdominal surgery. Two researchers independently identified reports and extracted data. We compared use of a barrier with no barrier for nine predefined outcomes, graded for clinical relevance. The primary outcome was reoperation for adhesive small bowel obstruction. We assessed systematic error, random error, and design error with the error matrix approach. This study is registered with PROSPERO, number CRD42012003321. FINDINGS Our search returned 1840 results, from which 28 trials (5191 patients) were included in our meta-analysis. The risks of systematic and random errors were low. No trials reported data for the effect of oxidised regenerated cellulose or polyethylene glycol on reoperations for adhesive small bowel obstruction. Oxidised regenerated cellulose reduced the incidence of adhesions (relative risk [RR] 0·51, 95% CI 0·31-0·86). Some evidence suggests that hyaluronate carboxymethylcellulose reduces the incidence of reoperations for adhesive small bowel obstruction (RR 0·49, 95% CI 0·28-0·88). For icodextrin, reoperation for adhesive small bowel obstruction did not differ significantly between groups (RR 0·33, 95% CI 0·03-3·11). No barriers were associated with an increase in serious adverse events. INTERPRETATION Oxidised regenerated cellulose and hyaluronate carboxymethylcellulose can safely reduce clinically relevant consequences of adhesions. FUNDING None.

Abstract
PURPOSE A clear definition of "complex (abdominal wall) hernia" is missing, though the term is often used. Practically all "complex hernia" literature is retrospective and lacks proper description of the population. There is need for clarification and classification to improve patient care and allow comparison of different surgical approaches. The aim of this study was to reach consensus on criteria used to define a patient with "complex" hernia. METHODS Three consensus meetings were convened by surgeons with expertise in complex abdominal wall hernias, aimed at laying down criteria that can be used to define "complex hernia" patients, and to divide patients in severity classes. To aid discussion, literature review was performed to identify hernia classification systems, and to find evidence for patient and hernia variables that influence treatment and/or prognosis. RESULTS Consensus was reached on 22 patient and hernia variables for "complex" hernia criteria inclusion which were grouped under four categories: "Size and location", "Contamination/soft tissue condition", "Patient history/risk factors", and "Clinical scenario". These variables were further divided in three patient severity classes ('Minor', 'Moderate', and 'Major') to provide guidance for peri-operative planning and measures, the risk of a complicated post-operative course, and the extent of financial costs associated with treatment of these hernia patients. CONCLUSION Common criteria that can be used in defining and describing "complex" (abdominal wall) hernia patients have been identified and divided under four categories and three severity classes. Next step would be to create and validate treatment algorithms to guide the choice of surgical technique including mesh type for the various complex hernias.

Abstract
BACKGROUND Because of high frequency, high morbidity, and difficulty of repair, incisional hernias in obese patients represent a particularly vexing and common problem for surgeons. The objective of this study was to describe a highly selective technique for incisional hernia repair with panniculectomy in the morbidly obese. We also describe perioperative characteristics and preliminary outcomes for a limited series of patients who underwent this procedure. METHODS We performed a preperitoneal partial mesh underlay with a panniculectomy (PUPP) on 10 patients with incisional hernias and a body mass index (BMI)>40 kg/m(2). The hernia repair was performed by a general surgery team, and the panniculectomy was performed by a plastic surgery team. We retrospectively analyzed perioperative variables for each patient. Phone interviews were conducted to obtain follow-up. RESULTS Mean patient age was 53 years (range 32-75 yr) with mean BMI of 46 kg/m(2) (range 41-60 kg/m(2)). Patients had a history of 3.4 average prior abdominal operations, and a median of 3 prior hernia repairs. The average operative time was 371 minutes with a mean estimated blood loss of 162 ccs. Three patients experienced a minor wound complication. There were no major wound complications, and the 30-day mortality rate was zero. At a median and average follow-up time of 805 and 345 days, respectively, one patient developed a hernia recurrence. Patients were satisfied with their appearance and the hernia repair, with mean satisfaction scores of 4.3 and 4.9 out of 5 (very satisfied), respectively. CONCLUSION The PUPP hernia repair is a viable option for incisional herniorrhaphy and concurrent panniculectomy in the morbidly obese.
