RESUMO
BACKGROUND: The avoidance of postoperative chronic pain is of the foremost importance and has a deep impact on patient satisfaction. The objective of this study is to evaluate the selective transabdominal preperitoneal laparoscopic neurectomy for treatment of refractory inguinodynia. METHODS: Prospective study in a University Hernia Center included 16 consecutive patients with chronic pain. Primary endpoint was pain control (measured by appropriate questionnaire and need of analgesics). Secondary endpoint was surgical morbidity. Follow-up was 2 years (range 12 months-4 years). RESULTS: The mean operating time was 52 (range 36-68) minutes, and there were no intraoperative complications. All patients had histologic confirmation of neurectomy. Anatomical variation was found in ten patients (62.5 %), being a common trunk ilioinguinal/iliohypogastric nerve the most frequent (nine patients, 56.25 %). One patient developed hypoesthesia in the territory of the femorocutaneous nerve by nerve injury. Reoperation was performed 6 months afterward to complete ilioinguinal nerve neurectomy. Neuropathic pain medications were continued by five patients. Pain was completely eliminated in 11 (68.75 %). CONCLUSIONS: Management of patients with neural groin pain should be done in a multidisciplinary unit. Selective neurectomy by a transabdominal preperitoneal laparoscopic approach is a safe and highly effective option in selected patients for the treatment of refractory postoperative chronic pain. Careful anatomical planning is essential to avoid inadvertent injuries and more suffering to these patients.

INTRODUCTION: There are two kinds of actinic proctitis--one is acute and self-limited, and lasts about 3 months; the other is chronic and develops months to years after radiation therapy. The incidence of chronic actinic proctitis is about 5-20% of radiated prostate tumors. OBJECTIVE: To evaluate the effectiveness of argon plasma coagulation in the treatment of chronic actinic proctitis. MATERIAL AND METHOD: A retrospective search of patients with the diagnosis of actinic proctitis. The number of argon plasma coagulation therapies needed to achieve the symptom resolution was analyzed. RESULTS: We found 22 patients with a diagnosis of actinic proctitis. Nineteen were males (86.7%) and three (13.6%) were females. Nineteen patients (86.4%) had a diagnosis of prostate adenocarcinoma, one had a diagnosis of squamous-cell cervix carcinoma (4.5%), and two had a diagnosis of endometrial carcinoma (9.1%). The mean number of coagulation sessions needed for symptom resolution was 2.58 (absolute range 1-7) with a median of 2 sessions. CONCLUSION: Multiple treatments are described in the literature. None of them have shown promising results. Our results suggest that argon plasma coagulation is effective in the treatment of this condition, and achieves a rapid and sustained response with few sessions and a good safety profile.

BACKGROUND: Nonmidline incisional hernia is a surgical problem of major interest, but to date, little information on this problem is available. This study aimed to analyze the results of nonmidline laparoscopic incisional hernioplasty in a multidisciplinary abdominal wall unit over the past 10 years. METHODS: This prospective study examined a series of 199 patients undergoing surgery for incisional hernia via the laparoscopic approach: 146 midline and 53 nonmidline. A comparative analysis compared midline and nonmidline defects, and a descriptive analysis compared four nonmidline types: 18 lumbar, 11 subcostal, 14 inguinal, and 10 lateral. Clinical and follow-up parameters were assessed during a mean follow-up period of 64 months (range, 12-120 months). RESULTS: The nonmidline incisional hernias were significantly larger, involved more preoperative pain, and required a longer hospital stay than the midline incisional hernias (p < 0.001). Also, the intraoperative complications and the consumption of analgesics were more frequent in the nonmidline group (p < 0.05). The postoperative morbidity and recurrence rates were similar in the two groups. No statistical differences were noted between the four types of nonmidline incisional hernias. The most common nonmidline type was lumbar hernia (34%). Hematomas (17%) predominated in the inguinal types, and pain predominated in the lumbar types. Two early recurrences were diagnosed for poor mesh placement: one subcostal and one lumbar. CONCLUSIONS: Laparoscopic incisional hernioplasty can be applied to nonmidline defects with the same rates of morbidity and recurrence as for patients with midline defects. The four types of nonmidline defects seem to have their own evolutionary characteristics.

Parapubic hernia is a rare entity, the aetiology of which is usually associated with pelvic surgery, traumatisms and bone malformations. Treatment is difficult because the defect is usually limited by altered fibrotic anatomical planes. We present a case of incisional pubic hernia in a patient with congenital bladder exstrophy and multiple surgeries for pelvic reconstruction, who was treated using a plasty combined with a double intra-abdominal/supra-aponeurotic mesh. The therapeutic possibilities are described for the laparoscopic and open approaches in the management of these complex hernias.

BACKGROUND: Lumbar hernias are uncommon defects of the posterior abdominal wall. Surgical treatment is still controversial in these cases. The aim of this study was to compare outcome and costs of the laparoscopic approach vs the open method. METHODS: We conducted a prospective nonrandomized study of 16 patients who underwent operation for secondary lumbar hernia between January 1997 and January 2003. Nine were treated via the laparoscopic approach and seven with an open technique. The following variables were analyzed: clinical data, hospital data (operating time and length of stay), patient comfort (consumption of analgesics and time to return to normal activities), and recurrences. Hospital costs were also analyzed. RESULTS: There were no differences between the two groups in terms of age and history, although the defects of the patients in the laparoscopic group were smaller. Mean operating time, postoperative morbidity, mean hospital stay, consumption of analgesics, and time to return to normal activities were significantly lower in the laparoscopic group (p < 0. 01). No were there any statistical differences between the two types of surgical procedure in terms of hospital costs. However, the final cost did show differences when expenses for readmissions and recurrences were taken into account (p < 0.01). CONCLUSION: The laparoscopic approach to secondary lumbar hernia repair is more efficient and more profitable than the traditional open technique.

El objetivo de este estudio fue investigar la presencia de ß-lactamasas de espectro extendido (BLEE) en Klebsiella pneumoniae aisladas en el Hospital de Niños de Córdoba. Las cepas fueron obtenidas de pacientes internados entre enero de 1996 y julio de 2000. Se encontró un total de 150 aislamientos productores de BLEE. En el año 1996 la prevalencia de BLEE en K.pneumoniae fue del 20 por ciento, mientras que desde 1998 se ha mantenido en valores próximos al 60 por ciento. Estudios fenotípicos como la determinación del punto isoeléctrico (pl) y el antibiotipo realizados sobre un grupo de 32 aislamientos seleccionados al azar demostraron la presencia de dos tipos de enzimas. El 81 por ciento mostró una BLEE con pl=7,9 y mayor actividad sobre cefotaxima y el 19 por ciento restante presentó una BLEE con pl=5,4 y mayor actividad sobre ceftacidima. No se detectaron aislamientos resistentes a imipenem ni a ciprofloxacina. La sensibilidad a otras drogas fue variable, siendo muy frecuente la resistencia asociada a gentamicina. Los determinantes de resistencia pudieron transferirse por conjugación a Escherichia coli.

Spigelian hernias are rare defects of the abdominal wall. Our aim is to analyse the bibliography and present a series of 28 patients. A Medline bibliographical study was performed between 1970 and 2000 with analysis of the number of cases, series, ratio of cases to year and type of journal. We also present a personal study and analyse epidemiological, diagnostic, and treatment factors. There are 159 articles, 479 cases, and 19 series of more than five patients published in 85 journals (42.3% medical). Our diagnosis was preoperative in 75%, and programmed surgery was 3.6 times more common than emergency surgery. We found a significant relationship between hospital stay and type of surgery (P < 0.02) and surgical technique used (P < 0.001). We found that spigelian hernias have a multidisciplinary interest; they are given almost equal treatment in medical and surgical journals; preoperative diagnosis can be established in 75% of cases; and the best results are offered by the extraperitoneal laparoscopic approach.

Laparoscopic repair of abdominal wall hernias is still a controversial and nongeneralized therapeutic option. The aim of this paper is to evaluate the results of laparoscopic surgery on abdominal wall hernias at a day-surgery unit and to describe our procedure protocol. Prospective analysis of 300 patients undergoing laparoscopic surgery for abdominal wall hernias was conducted: 260 preperitoneal and 40 intraperitoneal. The patients' clinical features, hernia type, intraoperative and postoperative complications, and follow-up are studied for both types of surgery. All the patients receiving surgery with extraperitoneal laparoscopy were completed as a day-surgical procedure with a rate of conversion to open surgery of 2.3%. Twelve (30%) of the 40 patients operated on for ventral hernias using intraperitoneal laparoscopy required hospitalization: five for perioperative complications and seven for pain (16%). There was no case of infection or mesh rejection. The recurrence rates were 0.78% (two cases) for the inguinal hernias and 2.5% (one case) for the ventral hernias. In conclusion, laparoscopic repair of abdominal wall hernias in a day-surgery setting is an efficient alternative to open surgery.

Lumbar hernias are an uncommon variety of abdominal wall defect. Diagnosis depends largely on the capacity for clinical suspicion, and confirmation is based on imaging tests. Surgical treatment is controversial due to difficulty in defining the borders of the lumbar defect and the involvement of a bone margin. We present a case of traumatic lumbar hernia in the Petit triangle, diagnosed by computed tomography (CT) and repaired laparoscopically as a major ambulatory surgery procedure. The laparoscopic approach enabled us to identify the whole of the lumbar area and effect a profound reconstruction on the same side as the defect.

Several types of crystalloids may be found in fine-needle aspiration cytology of salivary gland lesions. Amylase crystalloids (sometimes referred to as nontyrosine crystalloids) are tabular structures with frequent pointed ends that have received little attention until recent years. We report on a parotid cyst containing the latter type of crystalloids in a 51-yr-old white woman. The cytologic and radiologic findings were diagnostic of sialolithiasis. To the best of our knowledge, amylase crystalloids have been observed only in benign salivary gland lesions. Although this statement may be helpful in the diagnostic workup of patients presenting with parotid lumps, we do not recommend rendering a specific diagnosis based on the presence of such crystalloids. Good clinical and radiological correlation, as well as close follow-up, is mandatory in this setting.

Ventral hernia repair is still a difficult problem for surgeons because of the high recurrence rate and possible postoperative complications. Repairs with a prosthesis have reduced the recurrence rate, but the anterior approach still involves high morbidity and a long hospital stay. The purpose of this article was to evaluate the results of laparoscopic surgery on ventral hernias using a new double-layer mesh in an intra-abdominal position. A retrospective analysis was performed of the first 20 patients undergoing laparoscopic surgery for ventral hernia (75% incisional and 25% umbilical) with intra-abdominal prosthetic repair using a double-layer mesh consisting of three-dimensional multifiber polyester on one side and a hydrophilic resorbable nonstick collagen membrane on the other (Parietex composite, Sofradim, Villefranche sur Saone, France). The procedure was done on an outpatient basis in 85% of the cases. There was no morbidity or mortality. During a mean follow-up period of 10 months we found no infections, rejections, fistulas, recurrences, or alterations in bowel function. Laparoscopic repair of ventral hernias is an efficient alternative to open repair, with a low morbidity rate and short hospital stay. The double-layer mesh is safe for intra-abdominal use.

Chest wall hamartoma is a rare non-neoplastic benign lesion occurring in the neonatal period with particular clinical, radiological and pathological features. Histologically, it is composed of a mixture of bone trabeculae with spindle-cell stroma, chondroblast-like cells, and mature and immature hyaline cartilage. Aneurysmal bone cyst is a benign lesion that may arise secondary to several bone processes, such as giant cell tumor, chondrosarcoma, non-ossifying fibroma or osteosarcoma. We present two new cases of chest wall hamartoma with secondary aneurysmatic bone cyst formation studied with histological and immunocytochemical methods.

Introduction: The creation of Outpatient Surgery (OPS) units to combine the quality of medical attention and rationalize costs allows for greater efficiency in the use of resources. Aim: To report our series of patients undergoing surgery at the OPS units integrated into our Hospital (Type II): Patients and method: Between May 1994 and March 1998, 832 outpatients, of a total of 5230, underwent surgery at our General Surgery Unit. The criteria for exclusion from the programme depended on the patient and the enviroment or resulted from the operation itself. Results: Mean patient age was 47.5 years; there were 420 males and 412 females. Surgery was performed for 229 inguinofemoral hernias, 47 umbilical-epigastric hernias, nine incisional hernias, 193 pilonidal sinuses, 156 mammary nodules, 65 varicose veins, 64 arteriovenous fistulae and 69 proctology operations. The most common anesthesia techniques performed were rachianesthesia and local anesthesia. Eight point seven percent of the patients required admission (OPS failure), the most frequent causes being excessive pain, orthostatic-syncopal hypotension, nausea and vomiting and urine retention. There was no morbidity or mortality. Conclusion: OPS is a highly efficient procedure for resolving the most common pathologies in General Surgery. The anesthesia technique was an important factor in the rate of failure.
