P069 IMPLEMENTATION OF A TAP BLOCK PROTOCOL IN OUTPATIENT LAPAROSCOPIC HERNIA REPAIR DURING COVID PANDEMIC

Aim “COVID has been a great challenge since its beginning. Hospitals had to change/create a lot of clinical pathways and protocols to fight it. As an adaptation to COVID pandemic, our surgical department decided to implement a protocol of Transversus Abdominis Plane Block (TAPB) in laparoscopic incisional ventral hernia repair to allow these patients to be shifted from elective to outpatient regime. This study aimed to analyze the implementation of this protocol during the covid era as a way to have more resources available for COVID patients.” Material and Methods “A retrospective observational study was conducted using data since the beginning of the implementation of the protocol, from July 2020 to May 2021. TAPB was performed in all patients, laparoscopically or ultrasound-guided. Patients and hernia variables were identified using the hospital database. Data was recorded in the recovery room, by a phone call 24h post-surgery and in postoperative consultations with the surgeon.” Results “A total of 18 patients with incisional ventral hernia was included in the study. All patients had laparoscopic incisional ventral hernia repair surgery with TAPB and in ambulatory regime, discharged before 24h, are very satisfied with the protocol in terms of post-operative pain and there are no complications related to the TAPB.” Conclusions “This study found that, despite of COVID Pandemic, implementing a TAP Block procedure during laparoscopic incisional ventral hernia repair, allows to shift these patients from elective to outpatient surgery without compromising the outcomes, pain management and patient security, and, finally, to increase availability of resources for COVID patients.”

SP7.2.5 Robotic incisional/ventral hernia repair is feasible approach compared to laparoscopic repair: a systematic review

Aims Robotic incisional/ventral hernia repair (R-IVHR) is gaining popularity due to higher safety as well as feasibility profile. The objective of this study is to present a systematic review exploring the role of robotics compared to laparoscopic approach in the management of incisional/ventral hernia. Methods A systematic review of all types of comparative studies until January 2021 published on Embase, Medline, PubMed, PubMed Central and Cochrane databases reporting the clinical outcomes in patients undergoing either R-IVHR versus Laparoscopic (L-IVHR) was performed. Results A total of 8289 patients in 7 studies were included. There was minimal heterogeneity (Tau2 = 0.29, chi2 = 9.10, df, I2 = 45 %) among included studies for the variables of recurrence rate and post-operative complications, but statistically significant heterogeneity (Tau2 = 1.05, chi2 = 132.81, I2 = 96 %) was observed for the duration of operation. In the random effects model analysis using the statistical software Review Manager, statistically the R-IVHR prolonged the duration of operation (Standardized mean difference, 2.24; 95% CI, 1.37, 3.11; z = 5.06; P = 0.00001) but the post-operative complication rate (OR 0.63; 95% CI, 0.30, 1.34; z = 1.20; P = 0.23) as well as the recurrence rate (OR 0.63; 95% CI, 0.14, 2.74; z = 0.62; P = 0.53) were similar. Conclusion R-IVH repair is feasible and safe, but the duration of operation is significantly longer. Major multi-center randomized controlled trial is mandatory to assess the long terms outcomes and cost effectiveness before the routine use of R-IVHR.

General views on treatment technologies for patients with incisional ventral hernia

Nowadays, the problem of surgical treatment of incisional ventral hernia (IVH) still remains significant. According to the statistical data, the number of patients with postoperative ventral hernias has increased by more than 9 times over the past 25 years. Experts offer many solutions to this problem every year and the surgeon have to find the best method of postoperative rehabilitation in the flow of information. Academic research databases Google Scholar, CyberLeninka and others were used to search for the relevant literature. The following conclusions were drawn from this review. The etiology of IVH is multifactorial. There is no generally accepted evidence-based gradation of risk factors. There is no unified system for selecting the method of hernia repair of the anterior abdominal wall in patients with IVH. The choice of allotransplant material and the method of hernia repair are often individual. The value of the critical level of intraabdominal pressure have not been specified, however, all authors agree that its monitoring should become routine. The sublay technique remains the "gold standard" of plastic surgery by aponeurotic flap, inlay should be used when sublay is impossible to perform. Onlay should be used as a reserve method. In some situations, combinations of techniques are required. More and more laparoscopy is being introduced in the treatment of IVH as an assistance and in therapy. The introduction of new methods of hernia repair based on the uncontrolled separation of the anatomical structures of the abdominal wall imposes special requirements on surgical technology: plastic material, instrumental and technical support, wound closure and pharmacological support, especially in conditions of increased intra-abdominal pressure and tissue tension. We can use medication of pyrimidine’s row (xymedon) for a better implantation of the mesh implant and to increase the resistance of local tissues.

Efficacy evaluation of case-specific approach for surgical treatment of incisional ventral hernia

The Aim of research is to improve the results of surgical treatment of incisional ventral hernia by applying a case-specific approach and a new method of plastic repair of anterior abdominal wall. The prospective controlled dynamic study is based on incisional ventral hernia treatment results with the use of meshed endoprostheses among 219 patients. On-lay alloplasty was used in patients younger than 60 years of age, without severe concomitant pathology, with small and medium hernias and anterior abdominal wall defect of up to 10 cm (W1 - W2). The article shows a selection algorithm for anterior abdominal wall plastic repair method. It goes through advantages of the author’s proprietary technique. The article displays frequency and patterns of complications, life quality of the patients after various prosthetic plastic repairs. In the main group, positive treatment results were observed in 65.0%, long-term results of the operation were observed in 88.4%, complications occurred in 13.6%, relapse in 4.5%. «On lay» treatment tactics showed positive results in 59.4%, long-term results of the operation were observed in 74.7%, complications occurred in 40%, relapse in 3.1%. After «sub lay» intervention, excellent results were observed in 40.0% of patients, long-term results of the operation were observed in 81.9%, complications occurred in 12%, and relapse in 1.4%.
