Background: Substantial variation exists when performing a minimally invasive right hemicolectomy (MIRH) due to disparities in training, expertise and differences in implementation of innovations. This study aimed to achieve national consensus on an optimal and standardized MIRH technique for colon cancer and to develop and validate a video-based competency assessment tool (CAT) for MIRH. Method: Statements covering all elements of MIRH were formulated. Subsequently, the Delphi technique was used to reach consensus on a standardized MIRH among 76 colorectal surgeons from 43 different centres. A CAT was developed based on the Delphi results. Nine surgeons assessed the same 12 unedited full-length videos using the CAT, allowing evaluation of the intraclass correlation coefficient (ICC). Results: After three Delphi rounds, consensus (≥80% agreement) was achieved on 23 of the 24 statements. Consensus statements included the use of low intra-abdominal pressure, detailed anatomical outline how to perform complete mesocolic excision with central vascular ligation, the creation of an intracorporeal anastomosis, and specimen extraction through a Pfannenstiel incision using a wound protector. The CAT included seven consecutive steps to measure competency of the MIRH and showed high consistency among surgeons with an overall ICC of 0.923. Conclusion: Nationwide consensus on a standardized and optimized technique of MIRH was reached. The CAT developed showed excellent interrater reliability. These achievements are crucial steps to an ongoing nationwide quality improvement project (the Right study). The Delphi technique was employed to achieve a broad national consensus on 23 statements among 76 colorectal surgeons, defining a standardized MIRH. This standard includes complete mesocolic excision, intracorporeal anastomosis and Pfannenstiel incision using a wound protector. Building upon this consensus, a video-based competency assessment tool was developed, exhibiting excellent reliability. [ABSTRACT FROM AUTHOR]

Introduction: Abdominal wall closure in postoperative burst abdomen remains challenging. Different techniques vary between definitive closure and temporary closure. The aim of this study was to examine the short-term outcomes for different closure techniques., Materials and Methods: A multicenter single-arm observational retrospective cohort study examined all patients who underwent emergency operative repair for burst abdomen between January 2010 and May 2020 in two hospitals situated in the Netherlands. Patients underwent definitive closure, static closure with inlay mesh, or dynamic closure with negative pressure wound therapy (NPWT). We evaluated patient and treatment characteristics, length of stay, complications, and survival., Results: 119 patients were assessed. Definitive closure was performed in 68 patients (57%), with mesh augmentation in 23 (33%). When temporary closure was performed, 45 patients (88%) underwent mesh bridging. Six patients underwent dynamic closure with NPWT. Mesh bridging resulted in a shorter hospital stay (29 ± 16 days vs. 93 ± 46 days; p<0.001), less severe complications (46% vs. 100%; p=0.001), and less reoperations (20% vs. 100%; p<0.001) when compared to NPWT. There was no significant difference in 30-day and one-year mortality between all patient groups., Conclusion: Definitive closure of the burst abdomen should be performed if possible, depending on intraoperative findings. Our data suggest that mesh bridging for burst abdomen is a valuable alternative in terms of hospital stay, severe complications, and reoperations when compared to NPWT. It can be considered in cases where definitive closure is not feasible.

Purpose: Abdominal wall hernia repair in contaminated cases remains a therapeutic challenge due to the high risk of post-operative surgical site occurrences (SSO). Slowly resorbable synthetic (biosynthetic) meshes have recently been introduced and may offer unique advantages when challenged with bacterial colonization during abdominal wall reconstruction., Methods: A multicenter single-arm retrospective observational cohort study examined all consecutive patients in whom a poly-4-hydroxybutyrate mesh (Phasix™ or Phasix™ ST; Becton Dickinson, Franklin Lakes, NJ, USA) was used for the repair of an inguinal or ventral/incisional hernia, or to replace an infected synthetic mesh. Patient records were analyzed according to the level of contamination, using the classification score of the Centers for Disease Control and Prevention (CDC). The primary objective was to evaluate short-term postoperative morbidity by assessing SSOs and the need for reoperation or even mesh excision., Results: A total of 47 patients were included. The median age was 68 years (30-87), the male/female ratio was 26/21, and the median BMI was 26.5 kg/m2 (16.4-46.8). There were 17 clean cases, 17 clean-contaminated, 6 contaminated and 7 dirty. Median follow-up time was 48 days. An SSO was seen in 4 clean (23.5%), 7 clean-contaminated (41.2%), 2 contaminated (33.3%) and 5 dirty cases (71.4%). A surgical site occurrence requiring procedural intervention (SSOPI) was seen in 2 clean (11.8%), 3 clean-contaminated (17.6%), 1 contaminated (16.7%) and 2 dirty cases (28.6%). Hernia recurrence was seen in 1 clean (5.9%), 2 clean-contaminated (11.8%) and 3 dirty cases (42.9%). Mesh excision had to be performed in only one case in the contaminated group., Conclusion: The Phasix™ mesh shows promising short-term results when used in contaminated hernia-related surgery. Even in contaminated or dirty conditions, with or without infection of the mesh, resection of the mesh only had to be performed once and patients could be managed either conservatively or by relatively minor reoperations. However, further research is needed to fully evaluate the safety and efficacy of these meshes.

Peristomal skin complications due to appliance leakage frequently occur in all types of ostomies, resulting in great emotional, social, and financial impact for patients., Purpose: This pilot study was conducted to evaluate the safety and use of a new, reusable, nonadherent, elastic device., Method: A convenience sample of nonhospitalized patients with ileostomies and colostomies was recruited through the Dutch ostomy patient association. Participant inclusion criteria stipulated the presence of ileostomy or colostomy, a body mass index (BMI) between 18 and 30, and presence of an osto-my for at least 1 month. Patients with existing prolapse or necrosis of the ostomy, inability to give consent, or concurrent usage of other aids to prevent leakage or skin problems were excluded. Participants were fitted with and asked to wear the appliance continuously for 4 weeks and report experiences in a structured diary. Patient charts were reviewed for baseline demographic characteristics that included age, gender, American Society of Anaesthesiologists classification, and BMI. Study nurses performed structured weekly interviews and inspections of the ostomies and peristomal skin. The primary outcome measure was occurrence of serious adverse events such as ostomy necrosis or perforation. Secondary outcome measures were patient reported incidents of leakage and satisfaction during wear and changing of the appli-ance. Peristomal skin complications also were recorded. Descriptive statistics were used to analyze results. In addition, subgroup analysis of patients with a parastomal hernia was performed because of the potential benefits of the device design in these cases., Results: Participants included 23 patients (16 with colostomies, 7 with ileostomies); 13 participants (57%) were female. Mean age and BMI were 64 years and 28.3, respectively. Six (6) patients had a parastomal hernia. Due to shifting or discomfort while wearing the appliance, 16 participants discontinued use before the end of the study and were excluded from analysis from the point they left the study. Mean duration of participation was 12.8 days. No adverse events occurred. Mean number of incidents of leakage/week decreased from 3.5 ± 4.9 at start of the study to 1.8 ± 1.3 at week 4. The mean number of pouches used/week decreased from 10.5 ± 5.4 to 8 ± 2.6. Peristomal skin reactions present in 15 patients at start of the study decreased to 1 patient at the end of the study. Patient satisfaction did not change over the course of the study. Patients with parastomal hernias had similar results., Conclusion: No serious adverse events were reported and leakage and skin irritation were found to improve, but participant dropout rate was high and average usage time was only 12.8 days, which limited interpretation of the results. The data suggest that the appliance may offer an (intermittent) alternative to existing ostomy materials for patients experiencing troublesome leakages, peristomal skin problems, or parastomal hernias, but further research is needed to explore these outcomes.

BACKGROUND A Neisseria gonorrhoea infection is one of the most common sexually transmitted diseases and can present both urogenitally and extragenitally. CASE DESCRIPTION A 55-year-old woman presented at the emergency room with general malaise, abdominal pain and fever. Despite extensive surgical, gynaecological and radiological investigations no clear cause could initially be found. She was subsequently admitted to the surgical unit for observation. During the admission period the patient developed diffuse peritonitis and her infection parameters were rising. Diagnostic laparoscopy revealed extensive terminal ileitis with a reactive infiltrate of the uterine fundus and purulent peritonitis. A PCR test of the abdominal exudate was strongly positive for Neisseria gonorrhoeae, but cultures remained negative. Following an 8-day course of antibiotic treatment with intravenous ceftriaxone, the patient recovered from her symptoms. CONCLUSION Terminal ileitis with peritonitis is an unusual extragenital manifestation of a gonococcal infection. In order to make a diagnosis, surgical exploration with cultures is sometimes indicated.
