Cláudio?BrescianiEmail author Rodrigo?Oliva?Perez Angelita?Habr-Gama Carlos?Eduardo?Jacob Alberto?Ozaki Carlos?Batagello Igor?Proscurshim Joaquim?Gama-Rodrigues 《Journal of gastrointestinal surgery》2005,9(8):1174-1181
Minimally invasive surgery has been proposed as the preferred treatment strategy for various gastrointestinal disorders due
to shorter hospital stay, less pain, quicker return to normal activities, and improved cosmesis. However, these advantages
may not be straightforward for laparoscopic appendectomy, and optimal management of remains controversial. One hundred forty-eight
patients with clinical and radiologic diagnoses of acute appendicitis treated in two different hospitals were retrospectively
reviewed. Seventy-eight patients underwent laparoscopic appendectomy in hospital A and 70 patients underwent standard appendectomy
in hospital B. Patients treated by either type of surgery were compared in terms of clinical and pathologic features, operation
characteristics, complications, and costs. There were no significant differences between both groups in terms of clinical
features, radiologic studies, complications, and final pathology findings (P > .05). Hospital stay was significantly shorter
and bowel movements recovered quicker in the laparoscopy group. However, overall and operating room costs were significantly
higher in patients treated by laparoscopy (P < .01). Our series show a subtle difference in terms of hospital stay and bowel
movement recovery, favoring patients treated by laparoscopy. However, these results have to be carefully examined and weighed,
because overall costs and operating room costs were significantly higher in the laparoscopy group.

Perineal hernia (PH) is formed by the protrusion of intra-abdominal viscera through a defect in the pelvic floor. This is a rare complication after conventional abdominoperineal resection, pelvic exanteration, proctectomy, and other pelvic procedures. The purpose of the present paper is to report 4 cases of PH after laparoscopic abdominoperineal resection for rectal cancer and to review literature data about the incidence, predisposing factors, and treatment of this challenging problem. When added to other 3 cases previously reported in the Brazilian series of laparoscopic surgery, this group of 7 cases comprises a PH incidence of 3.5% after rectal resection procedures. Surgical treatment is indicated only in symptomatic patients with no signs of cancer recurrence. Proposed methods of surgical repair include abdominal, perineal, or combined approaches to the hernia in association with the use of autologous tissues or prosthetic meshes. Preventive measures are represented by closure of the pelvic peritoneum whenever possible, primary perineal suture and wound care to avoid infection. 相似文献

Iron deficiency is endemic in much of the world, and food system-based approaches to eradication may be viable with new plant breeding approaches to increase the micronutrient content in staple crops. It is thought that conventional plant breeding approaches provide varieties of rice that have 400-500% higher iron contents than varieties commonly consumed in much of Asia. The efficacy of consuming high-iron rice was tested during a 9-mo feeding trial with a double-blind dietary intervention in 192 religious sisters living in 10 convents around metro Manila, the Philippines. Subjects were randomly assigned to consume either high-iron rice (3.21 mg/kg Fe) or a local variety of control rice (0.57 mg/kg Fe), and daily food consumption was monitored. The high-iron rice contributed 1.79 mg Fe/d to the diet in contrast to 0.37 mg Fe/d from the control rice. The 17% difference in total dietary iron consumption compared with controls (10.16 +/- 1.06 vs. 8.44 +/- 1.82 mg/d) resulted in a modest increase in serum ferritin (P = 0.10) and total body iron (P = 0.06) and no increase in hemoglobin (P = 0.59). However, the response was greater in nonanemic subjects for ferritin (P = 0.02) and body iron (P = 0.05), representing a 20% increase after controlling for baseline values and daily rice consumption. The greatest improvements in iron status were seen in those nonanemic women who had the lowest baseline iron status and in those who consumed the most iron from rice. Consumption of biofortified rice, without any other changes in diet, is efficacious in improving iron stores of women with iron-poor diets in the developing world. 相似文献

This study aimed to identify changes in knowledge and practices learned to prevent dengue fever in two areas of Catanduva, S?o Paulo State, from 1999 to 2001: a study area and a control area. The study included an initial quantitative survey, qualitative research, a preliminary diagnosis presented to the community to launch a discussion aimed at defining future actions, implementation of the actions in the study area with community participation (but without changes in the control area), and a final comparison of the two areas. Changes in the study area included: vector control workers began demonstrating preventive measures without removing potential breeding places or using larvicide; use of educational aids specific to the local reality; activities related to the residents priorities; and activities such as music, theater skits, scavenger hunts, and games to demonstrate the vector cycle. Potential domiciliary breeding sites were significantly reduced; the proportion of houses without breeding sites was significantly increased; and there was an increase in the percentage of individuals who recognized the larval form of the vector in the study area as compared to the control area. 相似文献

BACKGROUND: Recent improvements in video technology and surgical instrumentation have resulted in the application of minimally invasive techniques to many surgical procedures including splenectomy and adrenalectomy. Nephrectomy requires a long flank incision with division of abdominal musculature and possible subcostal nerve damage. Severe postoperative pain and a prolonged recuperative period may result, and the cosmetic outcome may not be satisfactory. A new surgical approach utilizing laparoscopic dissection and delivery of the kidney through a small incision was performed to circumvent these problems. The aim of this paper is to describe the technique of laparoscopic live donor nephrectomy (LLDN) and present the preliminary outcome. METHODS: Over the 12-month period between May 1997 and April 1998, 16 donors underwent donor nephrectomy by a laparoscopic approach. The procedure was assessed with regard to its safety, feasibility and advantages over the open method. RESULTS: All the nephrectomies were completed without conversion to an open procedure. The average postoperative pain score on a visual analogue scale of 1-10 was 2 in LLDN. The donors required 36 mg morphine on average over 36 h postoperatively. Postoperative stay averaged 3 days. One donor developed an infective complication along the wound drain tract which settled with adequate drainage and antibiotics. All the removed donor kidneys were transplanted with immediate good function. There were no surgical complications or graft losses. The recipients' serum creatinine was in the range of 96-181 mmol/L 3 months after transplantation. CONCLUSIONS: Significant potential advantages of LLDN include less postoperative pain, shorter hospitalization and decreased recuperative time. This preliminary experience indicates LLDN to be effective in terms of safety and feasibility. 相似文献

Complications and hazards of gastrointestinal endoscopy 总被引:4,自引:0,他引:4
The diagnostic and therapeutic contribution of fiberoptic endoscopy to the advancement of the knowledge of gastrointestinal disease and to its proper management is already established. Technical refinements in the new instruments and extensive acceptance of the advantages of the method makes fiberendoscopy a procedure widely used throughout the world. Therefore, the appreciation of its potential risk of complications and hazards is justified. This review summarizes the complications and hazards of fiberoptic gastrointestinal endoscopy gleaned from reports of endoscopic surveys and individual experiences. Causes and means whereby complications related to upper intestinal and colonic endoscopy can be prevented or treated are discussed.
Resumen La contribución de tipo diagnóstico y terapéutico de la endoscopia de fibra óptica al avance del conocimiento sobre las enfermedades gastrointestinales y sobre su adecuado tratamiento está ya bien establecida. Los refinamientos técnicos de los nuevos instrumentos, junto con una extensa divulgación de las ventajas de este método, hacen de la endoscopia de fibra óptica un procedimiento ampliamente utilizado en todo mundo. Es por ello que se justifica divulgar sus peligros y el riesgo potencial de complicaciones, y este artículo revisa tales peligros y riesgos a partir de investigaciones y de experiencias individuales. También se discuten las causas y los mecanismos por los cuales se pueden prevenir o tratar las complicaciones de la endoscopia del tracto gastrointestinal y en la colonoscopia.

The purpose of the present study was to determine the value of circular emorrhoidectomy (procedure for prolapse and hemorrhoids
[PPH]) on the basis of data collected prospectively during the initial experience of a group of Latin American surgeons. Between
2000 and 2001, PPH was performed using a circular stapler in 177 patients who had third- and fourth-degree hemorrhoidal disease.
The average age of the patients was 47.7 years (range 26 to 85 years). Anal bleeding was the most common preoperative complaint
(93.2%) followed by anal pain (60.2 %), anal itching (43%), and constipation (41 %). Hemorrhoids were classified as third
degree in 132 patients (74%) and fourth degree in 45 patients (25.4%). Skin tags were detected in 86 patients (48.8%) and
rectocele in 14 patients (7.9%). Data collected included patient demographics, type of anesthesia, and specific details of
the surgery such as duration of the operation, distance from the staple line to the dentate line, need for complementary hemostasis,
and any unexpected occurrences. Postoperative data collected included the degree of pain, which was evaluated on the basis
of the type and dosage of analgesics required, laxative consumption, and the presence of bleeding, fever, urinary retention,
or hematomas. Each patient completed a written questionnaire addressing these events. Patients returned for follow-up visits
on days 7, 15, 30, and 90. Responses to pain, bleeding, fever, anal continence, recurrence of hemorrhoids, and level of satisfaction
were compiled. The duration of the procedure ranged from 6 minutes to 2 hours (average 2 3 minutes), and most operations lasted
no more than 20 minutes, with the exception of one that lasted 2 hours because of intraoperative bleeding. Intraoperative
problems were minor. An additional one or a few sutures were required in 58.7% of patients to achieve perfect hemostasis.
In 128 patients (72.3%) the hospital stay was less than 24 hours. Same-day surgery was chosen for 37 patients (20.9%). Pain
was controlled with analgesia only using one to six doses of oral dipirona in 126 patients. Five patients were readmitted
to the hospital: four for control of bleeding and one for conventional hemorrhoidectomy due to an acute episode of external
hemorrhoidal thrombosis. At day 30, patients rated the efficacy of the procedure in alleviating preoperative symptoms as follows:
77.5% excellent; 16% good; 5.3% average, and 1.2% poor. At 3 months postoperatively no patient had had a recurrence of hemorrhoidal
prolapse, and there were no instances of stenosis or anal incontinence. Surgeons also rated the efficacy of the procedure
as excellent in 75%, good in 19.8%, average in 4.7%, and poor in 0.6%. With proper selection of patients and adequate stapling
technique, stapled hemorrhoidectomy may be considered safe; it is easily learned, has a satisfactory degree of pain, and is
well accepted by both patients and surgeons.
