RESUMEN

BACKGROUND AIMS: Stem cells, namely easily accessible bone marrow-derived cells (BMC), are reportedly capable of tissue repair in different damaged organs and might favor wound healing. The present study was undertaken to evaluate the feasibility and safety of BMC mobilization induced by granulocyte-colony-stimulating factor (G-CSF) in patients undergoing surgery for sacrococcygeal pilonidal cysts (SPC). To evaluate the possible clinical benefit of G-CSF in reducing the time to complete resolution, a comparison with a control group receiving surgery without G-CSF was performed. METHODS: Eight patients with complex SPC were included in this prospective trial. Patients were treated with G-CSF (5 µg/kg b.i.d.) for 3 consecutive days; standard surgical exeresis of the pilonidal cyst was scheduled on day 2 of mobilization. Mobilization was assessed in terms of circulating CD34(+) cells and granulocyte-macrophage colony-forming unit (CFU-GM) progenitors. RESULTS: Mobilization of CD34(+) cells and CFU-GM occurred in all patients, along with a marked increase in white blood cells (median peak value 28 435/µL, day 3). G-CSF was well tolerated and no adverse events occurred. All patients received the planned surgical treatment without any complications. Interestingly, the G-CSF group patients had a median time to resolution (117 days, range 110-130) significantly shorter than control patients (145 days, range 118-168) (P = 0.034). CONCLUSIONS: G-CSF administration, along with BMC mobilization, is feasible and well tolerated in patients undergoing surgery for SPC; clinical results compare favorably with those observed in controls not receiving G-CSF; the results suggest the potential use of G-CSF as an additional treatment to accelerate wound healing in patients undergoing surgery.

RESUMEN

Patients affected by peritoneal carcinomatosis are frequently submitted to repeated laparotomies to reduce intra-abdominal bulky lesions and to enhance the systemic chemotherapeutic action. Aim of our study is to evaluate feasibility and results of cytoreductive surgery and intraperitoneal chemohypertermic (IPCH) perfusion combined with Ramirez's abdominoplastic technique in selected patients with voluminous ventral hernias.At the same time, we support the hypothesis that Ramirez' technique would allow a normal intra-abdominal pressure leading to an optimal capability of penetration of chemotherapeutic agents in IPCH.From January 1998 to December 2003, 30 patients were submitted to a surgical debulking and IPCH through a laparotomic approach involving a ventral hernia. After extensive cytoreductive surgery, we closed the large abdominal wall damage with Ramirez's abdominoplasty technique, followed by IPCH. The technique described by Ramirez uses bilateral muscle flap complexes transposed medially to reconstruct the central abdominal wall without using meshes to supply or reinforce the abdominal reconstruction.A total of 23 patients (76.7%) were completely cytoreducted and subjected to IPCH. Postoperative mortality was 1/30 (3.3%). Major morbidity was 5/30 (16.7%). After a mean follow-up of 3 years, no sign of recurrent ventral hernia was noted in the survivors.This study suggests that surgical debulking combined with IPCH is feasible in patients with a previously large abdominal wall defect using the functional Ramirez's abdominoplasty technique. The reconstructive technique allows a regular IPCH procedure without recurrence of the ventral hernia confirmed by clinical examination and abdominal computed tomography.

RESUMEN

Cutaneous sebaceous carcinoma (SC) is a rare malignancy deriving from the adnexal epithelium of the sebaceous glands. Periorbital SC is approximately three times more common than extraorbital cutaneous SC. Extraocular SC is reported to be less aggressive than orbital sebaceous carcinoma and rarely metastasizes. We report a case of sebaceous carcinoma of the scalp, characterised by highly aggressive behaviour and huge invasion of the intracranial space. The patient was a 79-year-old woman who developed an infiltrating sebaceous carcinoma followed by lymph-node metastases shortly after excision of the primary lesion, resulting in death. In this case, aggressive biological behaviour was observed in a carcinoma arising in an extraorbital area, although it has traditionally been considered a less aggressive neoplasm.

RESUMEN

In the daily clinical practice of surgeons operating electively or, more frequently, in the emergency setting, within the abdominal cavity and pelvis, the detection of an intestinal adhesive disorder is frequent and is capable of causing numerous complications and subsequent reintervention. We report three cases of female patients referred to our observation for bowel subocclusion due to adhesive syndrome. After laparotomy, which revealed the presence of singular tenacious fibrovascular adhesions, the patients were subjected to immunohistochemical and receptor analysis yielding a diagnosis of leiomyomatosis peritonealis disseminata. The simultaneous combination of high levels of exogenous female hormones (hormone replacement therapy or prolonged exposure to oral contraceptives) or endogenous hormones (as happens during pregnancy), a genetic predisposition (including genetic malformations) and previous surgery (peritoneal trauma), as evidenced in our patients, all seem to play a key role in the pathogenesis of so-called "dense-vascularised", particularly tenacious adhesions responsible for the activation of multipotent mesenchymal submesothelial peritoneal cells. This striking macroscopic picture, when related to the anatomico-pathological description, is the basis of the pathological entity known as leiomyomatosis peritonealis disseminata.

RESUMEN

Destruction of the groin ligament is an unusual occurrence, often of traumatic or surgical origin. In the event of recurrent inguinal hernia with a destroyed inguinal ligament, the reconstruction of the wall with the surgical techniques currently available yields prognostically unfavourable results with frequent recurrence in only a short space of time. The aim of this report was to present a hernioplasty technique using the "three-sheet" implant involving reduction of the hernia sac and the affixing of two reinforcement nets in Prolene in an attempt to reconstruct the destroyed groin ligament. The three-sheet prosthesis simply consists of three sheets positioned in such a way (two polypropylene prosthesis are sutured one on top of the other perpendicularly and medially) as to form a new inguinal ligament; the first sheet reinforces the wall, reconstructing the posterior wall of the canal, and the second and third sheets support the peritoneum as in a hammock. From September 1995 to July 2006, 11 patients underwent such reconstruction operations in our division, 8 of them for recurrent inguinal hernia for multiple failure, 1 for an inguinal hernia with Cloquet's adenopathy and 2 secondary to femoro-femoral and iliac-femoral by-passes. To date, after a mean follow-up of 5 years, no recurrence has taken place. This method has proved safe and effective, with minimal risk of trauma and complications, and may therefore be indicated for the management of recurrent inguinal hernia with rupture of the inguinal ligament.
