Enterotomy Risk in Abdominal Wall Repair A Prospective Study
ABSTRACT To establish the incidence and predictive factors of enterotomy made during adhesiolysis in abdominal wall repair and to assess the impact of enterotomies and long-lasting adhesiolysis on postoperative morbidity such as sepsis, wound infection, abdominal complications and pneumonia, and socioeconomic costs.
Adhesions frequently complicate surgical repair of abdominal wall hernia. Enterotomies made during adhesiolysis specifically have a large impact on morbidity of patients, especially surgical site infections. Little is known on the incidence and burden of enterotomies and long-lasting adhesiolysis in abdominal wall repair.
Between June 2008 and June 2010 demographics, disease characteristics and perioperative data of all patients undergoing elective abdominal wall repair were included in a prospective cohort study that was focused on adhesiolysis-related problems. A trained researcher observed all surgeries and collected data on adhesion location, tenacity, adhesiolysis time, and inadvertent organ damage such as enterotomies. Primary outcome was the incidence of enterotomy, and predictive factors for enterotomy were assessed through univariate and multivariate analyses. In addition, we evaluated the impact of adhesiolysis and enterotomy on morbidity.
A cohort of 133 abdominal wall repairs was analyzed. Adhesiolysis was required in 124 (93.2%), with a mean adhesiolysis time of 35.7 ± 29.8 minutes. Thirty-three enterotomies were made in 17 patients (12.8%). Two patients had a delayed diagnosed bowel perforation. Adhesiolysis time, hernia size greater than 10 cm, and fistula were significant predictive factors in univariate analysis. In multivariate analysis, only adhesiolysis time was a significant and independent predictive factor for enterotomy (P = 0.004). Trends toward an increased risk were seen for patients with mesh in situ and hernia size greater than 10 cm. Patients with enterotomy had significantly more urgent reoperations (P = 0.029), and they more often required parenteral feeding (P = 0.037). Moreover, patients with extensive adhesiolysis (adhesiolysis time, >30 minutes) more often suffered from wound infection (9/63 vs 2/70; P = 0.025), abdominal complications (5/63 vs 0/70; P = 0.022), and sepsis (4/63 vs 0/70; P = 0.048).
One in 8 patients undergoing abdominal wall repair suffer inadvertent enterotomy following adhesiolysis. Adhesiolysis time predicts enterotomy. Morbidity in patients with extensive adhesiolysis and adhesiolysis complicated by enterotomy is high, inducing longer hospital stay and increased health care utilization.

ABSTRACT: The operative report contains critical information for patient care, serves an educational purpose and is an important source for surgical research. Recent studies demonstrate that operative reports are unstructured and lack vital components. The accuracy of the operative notes has never been assessed. The aim of this study was to analyse the accuracy of operative reports by comparing notes with intraoperative observer-derived findings regarding adhesions and adhesiolysis-related complications. The incidence of adhesions and adhesiolysis-induced injury were scored from the reports by a researcher blinded to operative findings obtained prospectively by direct observation. In addition, factors influencing correct reporting were analysed, including sex, surgical experience, delay in dictation, and the gradual introduction of a new report template with a focus on describing operative findings rather than actions taken. A total of 755 consecutive operative reports were analysed. Sensitivity and specificity for the incidence of adhesions was 85·1 and 72·4 per cent respectively. Six of 43 inadvertent enterotomies, and 17 of 48 other organ injuries, had not been reported. All missed bowel injuries were found in reports written in the old template. A median delay in dictating of 3 (range 1–226) working days was found for 56 reports (7·4 per cent). Documentation of inadvertent enterotomies was missing more often in delayed reports (2 of 3 versus 4 of 40 reports dictated with no delay; P = 0·022). The sensitivity and specificity of operative reports noting adhesions and adhesiolysis were low. One in seven enterotomies was not reported. Effort should be put into teaching timely, meaningful, structured and accurate reporting of surgical procedures. Copyright © 2012 British Journal of Surgery Society Ltd.

ABSTRACT: BACKGROUND: Laparoscopic incisional hernia repair with intraperitoneal mesh is associated with a certain degree of adhesion formation to the mesh. This experimental study examined the efficacy of several coated meshes for adhesion reduction. METHODS: Five commercially available meshes with a layered coating were placed intraperitoneally in rats and followed up for 90 days: polypropylene and polyester meshes, both coated with absorbable collagen (Parietene Composite and Parietex Composite, respectively), and three polypropylene meshes respectively coated with absorbable omega-3 fatty acids (C-Qur Edge), absorbable cellulose (Sepramesh IP), and nonabsorbable expanded polytetrafluoroethylene (Intramesh T1). Uncoated polypropylene and collagen meshs (Parietene and Permacol, respectively) served as the control condition. Adhesions, incorporation, and tissue reaction were evaluated macro- and microscopically. Additionally, the development of the neoperitoneum was examined. RESULTS: All the coated meshes performed equally well in terms of adhesion reduction. The collagen mesh performed comparably, but the uncoated polypropylene mesh performed significantly worse. The different coatings led to very differing degrees of inflammation. Ingrowth was observed only at the place of suture but was comparable for all the meshes except C-Qur Edge, which showed the weakest incorporation. Development of a neoperitoneum on the mesh surface occurred independently of whether an absorbable or nonabsorbable coating or no coating at all was present. CONCLUSIONS: Commercially available meshes with a layered coating deliver comparable adhesion reduction. The physical presence of a layered coating between the intraperitoneal content and the abdominal wall seems to be more important than the chemical properties of the coating in adhesion formation.Surgical Endoscopy 06/2013; 27(11).

ABSTRACT: 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. 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. 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. The PUPP hernia repair is a viable option for incisional herniorrhaphy and concurrent panniculectomy in the morbidly obese.Surgery for Obesity and Related Diseases 07/2013; 10(3).
