Hidradenitis suppurativa of the groin treated by radical excision and defect closure by medial thigh lift: aesthetic surgery meets reconstructive surgery.

INTRODUCTION: Hidradenitis suppurativa of the groin is a chronic, relapsing inflammatory disease of the skin and subcutaneous tissues. Radical surgical excision is the treatment of choice. Often split-skin grafting or wound healing by secondary intention are used for defect closure, sometimes with disfiguring results. We describe our experience with radical excision of localised inguinal hidradenitis suppurativa and immediate defect closure with a medial thigh lift. PATIENTS AND METHODS: Our hospital database was searched for all patients presenting to our institution for surgical treatment of hidradenitis suppurativa between 2001 and 2006. Only patients with hidradenitis confined to the groin were included. Exclusion criteria were simple abscess incisions, recurrence after previous grafting or flap surgery and extension of the disease outside the groin and presence of clinical signs of infection at the time of surgery. We documented patient demographics, sizes of defects, complications, time of follow-up, recurrences and patient satisfaction. RESULTS: A total of 8 patients with localised inguinal hidradenitis suppurativa were identified and 15 thigh lifts were performed. Defect size assessed on pathologic examination of the excised specimens averaged 15.9 cm x 4.3 cm x 1.3 cm (length x width x depth). All wounds but one healed primarily. Functional and aesthetic results were satisfactory. No major complications and no irritations of the genital area were observed. No recurrences were observed either. CONCLUSION: We propose the medial thigh lift to be considered for immediate defect closure after radical excision of localised inguinal hidradenitis suppurativa provided that no perifocal signs of infection are present after debridement.

Antibiotic prophylaxis to prevent local infection in oral surgery: use or abuse?

Antibiotics have a well-documented efficacy in the treatment of established infections and as prophylactic agents in medically compromised patients. However, the systematic administration of antibiotics to prevent local infections in fit patients is much more controversial. The aim of this paper is to reflect on the justification for prophylactic usage of antibiotics to prevent wound infection and to reason out the most appropriate antibiotic guidelines taking into account available scientific data and studies by other authors. Numerous clinical trials question the efficacy of antibiotics in preventing wound infection. While some studies establish that antibiotics reduce the incidence of postoperative infections, others compare their efficacy to that of placebo. Thus, scientific literature suggests that every oral surgical intervention is not tributary of systematic antibiotic prophylaxis to prevent local infections. Intrinsic surgical risk factors and the patient"s individual circumstances must be taken into account. Even though the efficacy of other antibiotics cannot be ruled out due to our limited comprehension of the bacteriologic interrelations intervening in the pathogenesis of postextraction local infection, the amoxicillin-clavulanic acid combination theoretically covers the complete odontogenic bacterial spectrum in Spain. When the prophylactic use of antibiotics is indicated, this should be performed preoperatively, at high doses, and its extent should not exceed 24 hours. Special attention should be paid to antiinfectious local measures that can minimize infection risk during the wound"s healing period

Application of ultrasound in bone surgery: two case reports

The present study describes some of the applications of ultrasound in bone surgery, based on the presentation of two clinical cases. The Piezosurgery® ultrasound device was used (Tecnología Mectron Medical, Carasco, Italy). In one case the instrument was used to harvest a chin bone graft for placement in a bone defect at level 1.2, while in the other case a bony window osteotomy was made in the external wall of the maxillary sinus, in the context of a sinus membrane lift procedure. The Piezosurgery® device produces specific ultrasound frequency modulation (25-29 kHz), and has been designed to secure increased precision in application to bone surgery. This instrument produces selective sectioning of the mineralized bone structures, and causes less intra- and postoperative bleeding. One of the advantages of the Piezosurgery® device is that it can be used for maxillary sinus lift procedures in dental implant placement. In this context it considerably lessens the risk of sinus mucosa laceration by preparing the bony window in the external wall of the upper maxilla, and can be used to complete the lifting maneuver. The use of ultrasound in application to hard tissues can be regarded as a slow technique compared with the conventional rotary instruments, since it requires special surgical skill and involves a certain learning curve.

Malignant gastroduodenal obstruction: palliation with self-expanding metallic stents.

PURPOSE: To evaluate the feasibility, efficacy, and tolerance of self-expanding metallic stent insertion under fluoroscopic guidance for palliation of symptoms related to malignant gastroduodenal obstruction. MATERIALS AND METHODS: Seventy-two patients (38 men, 34 women) aged 25-98 years (mean, 62 years) with duodenal (n = 43), antropyloric (n = 13), surgical gastrojejunostomy (n = 10), or pyloroduodenal (n = 6) malignant obstruction were referred for insertion of self-expanding metallic stents over a 6-year period. Stent insertion was performed with use of a peroral or transgastric approach when necessary (n = 11). RESULTS: Stents were successfully inserted in 70 of the 72 patients (97%) and provided symptom relief in 65 patients (90%). Inserted stents were mainly uncovered vascular (n = 55) or enteral (n = 10) Wallstents. One hundred eight stents were initially inserted: one, two, three, or four stents were indicated in 43, 17, nine, and one patient, respectively. Mean follow-up was 119 days (range, 4-513 days). Mean stent patency was 113 days (range, 4-513 days). Mean survival of patients was 120 days. During follow-up, stent obstruction occurred in seven patients as a result of tumoral overgrowth (n = 5) or ingrowth (n = 2). Complications occurred in 12 of the 72 patients (17%), including stent migration (n = 8), stent fracture (n = 1), duodenal perforation (n = 1), and death related to general anesthesia (n = 1). CONCLUSION: Despite a significant complication rate, self-expanding metallic stent insertion under fluoroscopic guidance appears to be a feasible and useful technique in the palliative management of malignant gastroduodenal obstruction.
