RESUMO
OBJECTIVE: To compare the diagnostic and therapeutic accuracy of laparoscopic appendectomy versus open appendectomy. BACKGROUND DATA: Appendectomy is the treatment of choice for acute appendicitis. Open Appendectomy (OA) has its complications rates (10-20%) and negative explorations in young women are about 25-30%. Acute appendicitis has a 3.1% morbidity and with perforation up to 47.2% and a mortality rate less than 1%. Advantages of laparoscopic appendectomy (LA) has been shown in many studies with lower intraoperatory and postoperatory complications, less hospitalization days, lower pain and faster return to daily activities when its compared with OA. METHODS: We perform a retrospective and descriptive trial with 1,883 patients with acute appendicitis between January 2000 to September 2004. Patients smaller than 15 years old and with other postoperatory diagnosis were excluded. Ji2 and t Student statistic tests were performed. RESULTS: We obtained 1,272 patients with acute appendicitis, 49% male and 51% female. LA was performed in 732 patients, 46.1% male and 53.9% female and OA was performed in 541 patients, 52.6% male and 47.3% female. Similar midage patients in both groups. LS was performed in 180 patients with complicated appendicitis and 116 patients by OA. LA was converted to open surgery in 4.5% patients. Morbidity was lower for laparoscopic group with statistical difference. There were no difference in fasting and hospitalization days. CONCLUSIONS: This procedure is a good choice for differential diagnosis overall in young women and complicated appendicitis with lower morbidity than the OA.

BACKGROUND: Lipomas are the most frequent benign tumors of the digestive tract and 50% are localized in the colon. Most are found submucosally and may vary in their incidence, localization, symptoms and pathogenesis, making diagnosis difficult. We undertook this study to learn the different presentations of an ileocecal valve (ICV) lipoma and conduct a review of the literature due to this uncommon location. CASE PRESENTATION: We present the case of a 78-year-old female with intermittent small bowel occlusion, abdominal distention and constipation. Colonoscopy showed a submucous tumor at the ICV, CT scan showed a tumor at the ICV with fat density. Laparotomy was performed with primary resection of the lesion by cecotomy, frozen section was reported as nonmalignant so a primary closure without ICV involvement was achieved. Definitive pathology revealed a benign lipoma. CONCLUSION: It is important to know the different presentations of these benign tumors because if there is mucosal ulceration they can be mistaken for a malignant lesion and lead to greater resections. Resection is necessary if they are symptomatic or >2 cm.

BACKGROUND: We undertook this study to identify the main causes leading to a failed funduplication and to determine the feasibility and effectiveness of reoperation by laparoscopic approach. METHODS: A retrospective and descriptive study was carried out with a review of patient charts. Patients were reoperated for failed antireflux surgery between January 1999 and September 2004. RESULTS: Sixteen patient charts were reviewed, 10 men (62.5%) and 6 women (37.5%), average age 42.1 +/- 15.4 years (21 to 72 years). Main preoperative symptoms were severe reflux in seven patients (43.7%), severe dysphagia in five (31.3%), and dysphagia and pain in four (25%). Thirteen patients (81%) had previous Nissen laparoscopic funduplication (NL), one (6%) open Nissen (ON) and two (13%) open Toupet (OT). Four patients were reoperated with open surgery (two Nissen and two Toupet), and 12 laparoscopically (11 Nissen and 1 Toupet). The main causes of dysfunction were a) in LN: sliding of the funduplication in five patients (38%), angulation of the funduplication in three (23%) and others; b) in ON: sliding of the funduplication in one patient; and c) in OT: posterior sliding of the funduplication in two cases. The hospital stay for the laparoscopic group was 3.5 +/- 1 days (2 to 5 days) and for the open group, 5.2 +/- 1.3 days (4 to 7 days, p < 0.013, Student t-test). Morbidity 1 month postoperatively was 37.5%. Also reported were abdominal distention (19%), occasional distention with dysphagia (12%), reflux (6.5%), with 0% mortality. CONCLUSIONS: Laparoscopic reoperation for failed antireflux surgery is feasible with an acceptable morbidity and good results.

BACKGROUND: Laparoscopic fundoplications are the standard surgical treatment of patients with gastroesophageal reflux disorder. Adequate technique is the most important outcome factor. There is no standardized method to evaluate the procedure itself. Intraoperative endoscopy is a method to evaluate laparoscopic fundoplications. MATERIAL AND METHODS: This was a retrospective observational study of patients undergoing laparoscopic fundoplications from July 1999 to June 2004, excluding open procedures and reoperations of previous failed laparoscopic fundoplications. Intraoperative endoscopy was performed during the dissection and suturing of the procedure to determine if correction of the technique is necessary. Number of changes were recorded and analyzed with Student's t-test. RESULTS: Three hundred patients were operated on, 23 were excluded (14 reoperations and nine conventional laparotomies). Of the 277 patients included, 178 were males and 99 females. Average age was 43.4 +/- 14 years (range: 12-85). There were 71 Toupet and 206 Nissen fundoplications. Intraoperative endoscopy determined correction of the technique in 77 patients with 1.69 +/- 0.96 changes; 68 rotated and/or angled fundoplications, one rotation with distended stomach, one redundant gastric fundus, and seven change in the type of fundoplication from Nissen to Toupet because of tightness (3.7 +/- 1.1 changes, p = 0.0001) to achieve adequate fundoplication. CONCLUSIONS: Intraoperative endoscopy confirms adequate technique and prevents inadequate laparoscopic fundoplications. Further studies will determine if routine use is justified to prevent postoperative complications and to improve outcome.

Introducción: los lipomas son los tumores benignos más frecuentes en tubo digestivo y hasta 50 % se encuentra en el colon. La mayoría son submucosos y varían de acuerdo a su incidencia, localización, sintomatología y patogénesis, lo que dificulta su diagnóstico. Nuestro objetivo fue conocer las diferentes manifestaciones clínicas causadas por un lipoma en la válvula ileocecal, y hacer una revisión de la literatura de esta localización poco frecuente. Caso clínico: mujer de 78 años que presentó cuadros repetidos de oclusión intestinal parcial con distensión abdominal, constipación y obstipación. Se realizó colonoscopia que mostró tumoración submucosa de 30 mm en válvula ileocecal; la tomografía computarizada de abdomen mostró tumoración nodular de densidad grasa en válvula ileocecal. La paciente fue sometida a laparotomía exploradora y cecotomía, donde se identificó y resecó tumoración submucosa, la cual fue enviada a estudio transoperatorio; dado que se trató de una tumoración benigna, se respetó la válvula ileocecal y se realizó cierre primario. El reporte histopatológico definitivo fue lipoma, negativo para malignidad. Conclusiones: es importante conocer las distintas formas de presentación de los lipomas, ya que fácilmente pueden confundirse con lesiones malignas (sobre todo si existe ulceración de la mucosa) y someter al paciente a procedimientos mayores. Sólo deben resecarse si producen síntomas o son mayores a 2 cm.
