A Novel Strategy for Preventing Posttransplant Large-For-Size Syndrome in Adult Liver Transplant Recipients: A Pilot Study

There are two causes of graft compression in the large-for-size syndrome (LFSS). One is a shortage of intra-abdominal space for the liver graft, and the other is the size discrepancy between the anteroposterior dimensions of the liver graft and the lower right hemithorax of the recipient. The former could be treated using delayed fascial closure or mesh closure, but the latter may only be treated by reduction of the right liver graft to increase space. Given that split liver transplantation has strict requirements regarding donor and recipient selections, reduced-size liver transplantation, in most cases, may be the only solution. However, surgical strategies for the reduction of the right liver graft for adult liver transplantations are relatively unfamiliar. Herein, we introduce a novel strategy of HuaXi-ex vivo right posterior sectionectomy while preserving the right hepatic vein in the graft to prevent LFSS and propose its initial indications.

A core outcome set for damage control laparotomy via modified Delphi method

ObjectivesDamage control laparotomy (DCL) remains an important tool in the trauma surgeon’s armamentarium. Inconsistency in reporting standards have hindered careful scrutiny of DCL outcomes. We sought to develop a core outcome set (COS) for DCL clinical studies to facilitate future pooling of data via meta-analysis and Bayesian statistics while minimizing reporting bias.MethodsA modified Delphi study was performed using DCL content experts identified through Eastern Association for the Surgery of Trauma (EAST) ‘landmark’ DCL papers and EAST ad hoc COS task force consensus.ResultsOf 28 content experts identified, 20 (71%) participated in round 1, 20/20 (100%) in round 2, and 19/20 (95%) in round 3. Round 1 identified 36 potential COS. Round 2 achieved consensus on 10 core outcomes: mortality, 30-day mortality, fascial closure, days to fascial closure, abdominal complications, major complications requiring reoperation or unplanned re-exploration following closure, gastrointestinal anastomotic leak, secondary intra-abdominal sepsis (including anastomotic leak), enterocutaneous fistula, and 12-month functional outcome. Despite feedback provided between rounds, round 3 achieved no further consensus.ConclusionsThrough an electronic survey-based consensus method, content experts agreed on a core outcome set for damage control laparotomy, which is recommended for future trials in DCL clinical research. Further work is necessary to delineate specific tools and methods for measuring specific outcomes.Level of evidenceV, criteria

Overview on Temporary Abdominal Closure Techniques: A Review

Open abdomen (OA) is becoming more common, primarily to prevent intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) following emergency abdominal surgery. The purpose of temporary abdominal closure (TAC) techniques is no longer just abdomen coverage; fluid regulation and early fascial closure are now important considerations. TAC techniques for leaving the abdomen open are numerous. The ideal one should be simple to apply and remove, allow for quick access to a surgical second opinion, drain secretions, ease primary closure with acceptable morbidity and mortality, allow for easy nursing, and, finally, be readily available and inexpensive. Over the years, several TAC methods have been proposed. In this review, we overview different techniques for temporary abdominal closure and its advantages and disadvantages.

Closure Versus Non-closure of Hernia Defect in Laparoscopic Ventral Hernia Repair with Mesh: a Systematic Review

There is a controversial premise about choosing a surgical approach in ventral hernia using laparoscopic repair. Some surgeons prefer to use mesh with closure while others prefer to use mesh without closure. This study aims to compare mainly the rate of recurrence in mesh repair with and without closure. A wide range of electronic bibliographic databases such as PubMed, Embase and Education Resources Information Center (ERIC) was searched. Based on the eligibility criteria, all studies which compared the results after hernia repair from 2010 to 2020 were incorporated. Following screening the abstracts, we ended up reviewing seven full-text articles, and data were extracted on important parameters such as demographic attributes of participants, sample size and recurrence rate of hernia. Of the total studies that were reviewed, three were randomized controlled trials (RCT’s) and four retrospective observational studies. The sample size of all included studies varied between 80 and 176. The findings appear promising for the fascial closure as it showed evidence of a significant reduction in the recurrence rate with P = 0.047 in one out of the three randomized controlled trials and in the retrospective observational studies reaching up to 16.7% recurrence reduction rate. Likewise, there is also a reduction in the bulging, surgical site infection and seroma formation with higher patient’s satisfaction and quality of life score. Primary fascial closure appears to be effective as it can decrease the rates of recurrence, seroma formation and bulging, and improve patient’s satisfaction and quality of life. Given the dearth of studies, mainly randomized controlled trials, there is a need to carry out large randomized controlled trials with enough follow-up.

Prevention of Incisional Hernia in Ovarian Cancer Patients Undergoing Midline Laparotomy

BACKGROUND: Incisional hernias (IH) are a frequent complication of midline laparotomies in abdominal surgery. This study was conducted in order to determine the efficacy of mesh placement and assess the optimal fascia closure technique to reduce the IH rate in patients surgically treated after being diagnosed with malignant or borderline ovarian tumors.METHODS: Retrospective data from patients undergoing midline laparotomy for borderline or ovarian cancer in Hospital del Mar, Barcelona, from January 2008 to December 2019 were collected. Patient demographic, preoperative and intraoperative characteristics and risk factors for hernia were reported. The incidence of IH between groups (mesh and non-mesh) and the technique used in fascial closure for each patient (small bites technique vs large tissue bites) was reported. RESULTS: In total, 133 patients with available data for follow-up were included. After clinical and radiological examination, 25 (18.79%) of them showed IH. 18 of 61(29.5%) patients in non-mesh group developed IH, compared with 7 of 72 (9.7%) in mesh group (OR 0.25, 95% CI 0.09-0.66, p<0.005). Patients of large tissue bites group showed higher prevalence of IH compared with small bites technique group without statistical significance (OR 0.46, 95% CI 0.17-1.24, p=0.119). The combination of mesh reinforcement and small bites technique for fascial closure significantly reduce IH risk (p=0.021). CONCLUSION: Incidence of IH is high in patients undergoing midline laparotomy for ovarian cancer or borderline ovarian tumor. The addition of a prophylactic mesh and use of small bites technique may reduce the incidence of IH and potentially minimize the social impact and costs of this complication.
