Hernies géantes avec perte de droit de cité : comment préparer au mieux les patients ?

Giant hernias with loss of domain induce physiological modifications that impair quality of life and make more complex their surgical management. A good preparation of patients before surgery is the key to an eventless postoperative course. The progressive pre-operative pneumoperitoneum (PPP) is one of the described abdominal augmentation protocols which can help patients to tolerate hernia content reintegration and avoid components separation technique during hernia repair. This article describes the management of these complex patients. We also report the case of a patient who follows successfully a PPP protocol

Discordant rejection in simultaneous pancreas and kidney transplantation: true discordance or analysis artefact ?

The article by Parajuli et al published in this issue of Transplant International is the latest, and perhaps the most convincing in a relatively small body of literature, to suggest that in a situation of simultaneous pancreas-kidney transplantation (SPK), in which both organs are from the same donor, one organ may be undergoing acute rejection independently from the other (1). The organ hierarchy in immunogeneicity and susceptibility to rejection is a long known biological phenomenon, with the liver at one end of the spectrum and the intestine the other. It was originally thought that such a hierarchy between kidney and pancreas was in disfavor of the latter (2). This article is protected by copyright. All rights reserved

Anal metastasis from recurrent breast lobular carcinoma: A case report

We report a case of isolated gastrointestinal metastasis from breast lobular carcinoma, which mimicked primary anal cancer. In July 2000, an 88-year-old woman presented with infiltrating lobular cancer (pT1/G2/N2). The patient received postoperative radiotherapy and hormonal therapy. Four years later, she presented with an anal polypoid lesion. The mass was removed for biopsy. Immunohistochemical staining suggested a breast origin. Radiotherapy was chosen for this patient, which resulted in complete regression of the lesion. The patient died 3 years after the first manifestation of gastrointestinal metastasis. According to the current literature, we consider the immunohistochemistry features that are essential to support the suspicion of gastrointestinal breast metastasis, and since we consider the gastrointestinal involvement as a sign of systemic disease, the therapy should be less aggressive and systemic

Repair of Large Abdominal Wall Defects Using Total Anterior Aponeurotic Flap: Anatomical Feasibility Study and Comparison with Ramirez's Technique

In this cadaveric study, we explored the feasibility of a maximal mobilization of the superficial abdominal fascia, in a continuous flap, to achieve a tension-free covering of midline defects. The aponeurosis of the external oblique muscle was incised along the anterior axillary line and then detached up to the anterior rectus sheath. The latter was opened between the external and the internal oblique aponeurosis while keeping the continuity with the external oblique fascia. The obtained flap was solid and uninterrupted. The width gain reached 15 ± 3 cm on each sides, providing tissue advancement 60% longer than Ramirez's technique (n = 8). The described technique allows large covering with respect to the anatomical planes. Further clinical tests should evaluate the validity of such concept in the repair of giant and asymmetrical hernias

Recurrence of type 1 diabetes after simultaneous pancreas-kidney transplantation in the absence of GAD and IA-2 autoantibodies

We report herein the patterns of type 1 diabetes recurrence in a simultaneous pancreas-kidney transplant (SPK) recipient, in the absence of rejection. A 38-year-old female underwent SPK for end-stage nephropathy secondary to type 1 diabetes. Fasting blood glucose, HbA1c, fructosamine, C-peptide and autoantibodies (GAD-65, IA-2) were monitored throughout follow-up. At 3.5 years post-SPK, HbA1c and fructosamine increased sharply, indicating loss of perfect metabolic control, despite C-peptide levels in the normal-high range. Exogenous insulin was restarted 4 months later. C-peptide levels abruptly fell and became undetectable at 5.5 years. Autoantibody levels, which were undetectable at the time of SPK, never converted to positivity. Pancreas retranspantation was performed at 6 years. The failed pancreas graft had a normal macroscopic appearance. On histology, there were no signs of cellular or humoral rejection in the kidney or pancreas. A selective peri-islet lymphocytic infiltrate was observed, together with near-total destruction of β cells. At 2.5 years post retransplantation, pancreatic graft function is perfect. This observation indicates unequivocally that pancreas graft can be lost to recurrence of type 1 diabetes in the absence of rejection. GAD-65 and IA-2 autoantibodies are not reliable markers of autoimmunity recurrence

Does near-infrared (NIR) fluorescence angiography modify operative strategy during emergency procedures?

Bowel viability can be difficult to evaluate during emergency surgery. Near-infrared (NIR) fluorescence angiography allows an intraoperative assessment of organ perfusion during elective surgery and might help to evaluate intestinal perfusion during emergency procedures. The aim of this study was to assess if NIR modified operative strategy during emergency surgery

Impact of the presence of median arcuate ligament on biliary complications after liver transplantation

Introduction: The presence of median arcuate ligament (MAL) during orthotopic liver transplantation (OLT) may cause a significant reduction of the arterial hepatic flow. The aim of the present study is to investigate the impact of MAL on biliary complications in patients who underwent OLT. Methods: We performed a retrospective case-control study among patients who underwent OLT in Geneva University Hospital between 2007 and 2017, depending on the presence or absence of MAL. The matching was performed according to age, gender, lab-MELD score at time of OLT and type of donor (living or dead). The presence of MAL was assessed by an expert liver radiologist on the preoperative CT angiographic evaluation. Results: The incidence of MAL was 6.1% (19 patients). Baseline characteristics were comparable between the two groups. No significant difference in biliary complications was found between patients with and without MAL (37% and 24% respectively). No patient presented hepatic artery thrombosis. After logistic regression, in patients with MAL, the MAL release and gastroduodenal artery preservation compared to no treatment, showed an odds ratio for post-OLT biliary complications of 1.5 and 1.25 respectively. There was no difference in overall graft survival and in hazard for biliary complications between patients with and without MAL. Conclusion: In the present study, we did not find any difference in the prevalence of biliary and arterial complications between patients with and without MAL. The choice of MAL treatment did not influence in a significant way the overall outcome and development of complications. However, if, at the end of arterial reconstruction, the arterial flow is not adequately established, MAL needs to be treated with the least invasive technique. This article is protected by copyright.

In situ liver splitting under extracorporeal membrane oxygenation in brain-dead donor

Hemodynamic instability is generally considered as a contraindication to liver splitting, in particular when using an in situ technique. We describe the cases of two young donors with brain death in whom refractory cardiac arrest and hemodynamic instability were supported by veno-arterial extracorporeal membrane oxygenation (VA-ECMO), allowing uneventful in situ splitting. Two adult and two pediatric liver recipients were successfully transplanted with immediate graft function. Favorable outcomes were also observed for the other transplanted organs, including one heart, two lungs, and four kidneys. Refractory cardiac arrest and hemodynamic instability corrected by VA-ECMO should not be considered as a contraindication to in situ liver splitting
