Modified enteromesenteric bridging operation for primary lymphedema.

BACKGROUND: Primary lymphedema represents a condition which affects the lymph vessels and their cells without any pathologic patient history leading to soft tissue swelling. They are described in the literature three types: congenital primary lymphedema, or Milroy disease, lymphedema praecox, which occurs in puberty, and lymphedema tarda, when, the same symptoms, develop over 35 years old patients. The aim of this paper is to present a modified Kimmoth's original procedure for a praecox lymphedema by introducing an omental flap in the resorptive area. CASE REPORT: We present a case of 18 year-old patient with a significant lymphedema of the lower limbs and genitalia associated with high-symptomatic under-knee and scrotal ulcerative, necrotic and inflammatory lesions. The ultrasound and computed-tomography scans showed bilateral hypertrophic lymph-nodes in the inguinal and external iliac areas. Considering this diagnosis we decided to perform a physiologic lymph drainage by combining the enteromesenteric bridge with the omental transposition. The postoperative course was favorable without wound complications. Three months after, it was resected the remnant scrotal sclero-lymphatic tissue. 3 years after surgery, the clinical follow-up showed a significant reduced lymphedema with 10 cm shank / 15 cm thigh circumference lost. CONCLUSIONS: The enteromesenteric bridge combined with the omental flap proved to be efficient in ensuring the lymphatic drainage in a case with proximal lymphatic occlusion.

Crossover iliofemoral bypass graft through tension-free abdominal wall-repair mesh.

INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall. We present our experience with the use of this particular surgical technique in patients with critical limb ischemia and with indication for extra-anatomic crossover bypass (high-risk patients with contra-indication for the transperitoneal approach, extensive calcified aortic or iliac wall which contraindicated the direct arterial reconstruction or secondary arterial reconstruction after the occlusion of an aorto- femoral graft). METHODS: In principle, the hernioplasty was performed by using the Lichtenstein tension-free hernia repair technique, followed by the crossover iliofemoral bypass. The main feature of this technique is to pass the vascular graft from the retroperitoneal space above the mesh through a calibrated hole in the mesh RESULTS: The 7 patients with inguinal hernia and l limb-threatening ischemia had favorable evolution, without hernia recurrence, limb-threatening ischemia or any graft complication at 3 years. DISCUSSION: Using this particular surgical technique we treated 2 surgical diseases using a single intervention for highrisk patients who had both inguinal hernia and contra-lateral critical limb ischemia. Being encouraged by the initial satisfactory results, we extended this technique even for the patients with indication of crossover iliofemoral bypass but without inguinal hernia. CONCLUSIONS: The particular surgical technique of the crossover bypass in which the vascular graft crosses a tension-free Polypropylene mesh from the retroperitoneal space toward the Retzius space represents an efficient and short procedure which treats simultaneously 2 different surgical diseases (inguinal hernia and contra-lateral critical limb ischemia) in high-risk patients. The results were satisfactory: we had no hernia recurrence and the limb-threatening ischemia was successfully treated. The preferred vascular graft for this particular technique is the reversed autogenous vein because its resistance to infections and the vein long-term patency is better than of a vascular prosthesis. When a prosthetic graft is required, we prefer to use the classic technique in which the crossover graft is placed in an under-aponeurosis site, in order to diminish the prosthesis infection risk.

How much does decompressive laparotomy reduce the mortality rate in primary abdominal compartment syndrome?: A single-center prospective study on 66 patients.

Contribution of decompressive laparotomy within the framework of the complex therapeutic algorithm of abdominal compartment syndrome (ACS) is cited with an extremely heterogeneous percentage in terms of survival. The purpose of this study was to present new data regarding contribution of each therapeutic step toward decreasing the mortality of this syndrome.This is a longitudinal prospective study including 134 patients with risk factors for ACS. The intra-abdominal pressure was measured every hour indirectly based on transvesical approach and the appearance of organ dysfunction. Specific therapy for ACS was based on the 2013 World Society of Abdominal Compartment Syndrome guidelines, which include laparotomy decompression. Management of the temporarily open abdomen included an assisted vacuum wound therapy.Of 134 patients, 66 developed ACS. The average intra-abdominal pressure significantly decreased after therapy and decompression surgery. The overall rate of mortality was 27.3% with statistical significance in necrotizing infected pancreatitis. Surgical decompression performed within the first 24 hours after the onset of ACS had a protective role against mortality (odds ratio <1). The average time after which laparotomy decompression was performed was 16.23 hours. The complications occurred during TAC were 2 wound suppurations and 1 intestinal obstruction. Wound suppurations evolved favorably by using vacuum wound-assisted therapy associated with the general treatment, whereas for occlusion, resurgery was performed after which adhesions dissolved. The final closure of the abdomen was performed at a mean of 11.7 days (min. = 9, max. = 14). The closure type was primary suture of the musculoaponeurotic edges in 4 cases, and the use of dual mesh in the other 11 cases.The highest mortality rate in the study group was registered in patients with necrotizing pancreatitis and the lowest in trauma group. Surgical decompression within the framework of the complex algorithm treatment of ACS contributed to the reduction of mortality by 8.7%. It is extremely important that the elapsed time since the initiation of the ACS until the surgical decompression is minimal (under 24 hours).
