摘要:
The laparoscopic treatment for gastroesophageal reflux (GR) by partial (PF) or total (TF) fundoplication is the current surgical treatment of choice after failure of appropriate medical treatment. The overall results with fundoplication include the initial learning period, during which the rate of complications, conversions, and duration of surgery and hospitalization are assumed to be greater. The aim of this study was to compare the results of laparoscopic treatment for GR in three groups of consecutive patients to determine the effect of the learning period on outcome. One hundred and fifty-six patients (88 men and 68 women) with an average age of 52.3 years (range, 18–78) were included. Surgery was indicated for failure or early relapse after the end of medical treatment or a symptomatic sliding hernia. The preoperative workup (endoscopy, barium meal, or esophageal pH monitoring) was governed by the clinical picture. The choice between TF and PF was based on the results of pH monitoring. Three groups of patients were chronologically defined. The parameters that were examined were the type of preoperative exploration, the type of fundoplication, the operative technique, the conversion rate, the mortality and morbidity rates, the duration of surgery and hospitalization, and the results at short- and medium-term follow-up. The three groups were comparable with respect to patient characteristics and the nature of their GR. All patients had an endoscopy, 91% had a barium meal, 77.5% underwent esophageal manometry, and 67% had pH monitoring. One hundred and thirty-six patients had a TF and 20 had a PF. Rossetti type TF became the reference procedure (67% in group III) and closure of the diaphragmatic crura was performed systematically in group III (100%). The duration of surgery was significantly reduced between groups I and groups II and III (140, 100, 80 minutes, respectively). The rate of conversion, due to a variety of causes, decreased from 9.8% to 3.8%, and then to 0%. The average duration of hospitalization decreased from 5.8 to 4.2 days (p = 0.01). There was no mortality and the morbidity rate decreased from 15% to 3.8%, and then to 0%. There were seven cases of relapse (4.6%), five in group I (10%) and two in group II (4%), with no cases in group III, although the follow-up in group III was shorter. There is an effect of the learning curve on the outcome of treatment for GR, and this must be taken into account in the training of surgeons (training within experienced departments and guidance during their initial interventions) and also in publications to allow a more accurate comparison of this technique with other treatments for GR.

摘要:
The clinical outcome of laparoscopic cholecystectomy in 63 patients with gallbladder dyskinesia (GD) and 60 patients with proven gallstone (GS) disease was compared. Patients were contacted to determine the extent of symptom relief and satisfaction after surgery. Patients with GD underwent significantly more diagnostic procedures than patients with GS and were found to have higher prevalence of other gastrointestinal motor disorders. Only 47% of patients with GD became completely asymptomatic after surgery, compared with 81% of patients with GS (p = 0.002). This was reflected in the satisfaction scores, which were 79% and 91%, respectively (p < 0.01). There was a significant difference in pathologic findings among the two groups; chronic cholecystitis was more frequently found in the GS group and the incidence of normal gallbladder was higher in the GD group. It is concluded that patients with GD have a good response to laparoscopic cholecystectomy. but they commonly experience continuing gastrointestinal symptoms related to other gastrointestinal motor disorders.

摘要:
The diode laser operates at a wavelength of 805 nm; indocyanine green (ICG) has a maximum energy absorption of a wavelength of approximately 800 nm. The effect of the diode laser as a laser knife can be significantly enhanced with an injection of ICG. In the present study, this dye-enhanced photothermal effect was investigated in the field of surgical endoscopy. A 9-cm2region of the canine gastric mucosa was removed by the laser after injection of 5 ml of ICG solution at a concentration of 0.5 mg/mL into the submucosal space. The diode laser was used at a power output of 10 watts. The canine stomach was removed 10 days after the operation to investigate the site histologically. Clinical application using transanal endoscopic microsurgery (TEM) was employed using a dye-enhanced laser in five patients with a rectal adenoma. The pathological changes in the canine gastric wall resected 10 days after the operation showed that the low-power laser enhanced by ICG produced less fibrosis in the submucosal space than electrocautery. Mucosal resection using a dye-enhanced laser was easily performed in these five patients. It was concluded that this easy removal of the mucosa by a dye-enhanced laser was due to its ability to produce hemostasis of the vessels and its excellent tissue-cutting effect.

摘要:
The aim of the present study was to establish the relationship between viability of the hydatid cyst and its ultrasonic appearance (Gharbi classification). To evaluate cyst viability, the criteria that were reported by the World Health Organization in 1982 for both the microbiological evaluation of the cystic fluid and the pathological evaluation of the cyst wall were used. In this study, the possibility of being viable was high in Type I cysts; the possibility of being dead was high in Type IV cysts. It is concluded that there is a relationship between ultrasonic appearance and the evolution of hydatid cysts.

摘要:
An evaluation of the results of the Brazilian experience in colorectal laparoscopic procedures in a multicenter prospective protocol done by the Brazilian Society of Colo-Proctology is presented. From December 1991 to August 1998, 1,161 patients (583 men and 578 women; mean age, 49.8 years), were operated on laparoscopically. Most of the procedures (40.5%) were for cancer, and the most common procedure was anterior resection (22.5%). The mean operative time was 189 minutes (3.1 hours). There were 42 (3.6%) perioperative complications; visceral injuries were the most common (1.4%). Conversions occurred in 122 (10.5%) cases. There were 148 (12.7%) postoperative complications; wound infections were the most common (5.2%). A liquid diet was started at a mean time of 1.4 days after the operation, and the mean hospitalization period was 6.4 days. The mortality rate was 1.5%.

摘要:
Laparoscopic low anterior resections using a triple stapling technique in five patients with rectal cancers (four Dukes A and one Dukes C) were performed. The location of the tumors was between 5 and 18 cm from the anal verge. For easy maneuverability, a 33-mm suprapubic port was used. In this technique, the Endo TA (the first stapler) is applied at the distal margin of the rectum to occlude the bowel. The bowel is irrigated with povidone-iodine solution and transected by an endolinear (the second) stapler. Anastomosis is completed by firing the circular (the third) stapler. The operative time was 177 ± 28.0 minutes, estimated blood loss was 41.7 ± 28.6g, and flatus appeared 1.8 ± 0.8 days after surgery. Follow-up studies have showed no local recurrence or distant metastasis. This procedure is safe and useful for performing laparoscopic low anterior resection.

摘要:
Quality of life (QOL) after video-assisted thoracic surgical (VATS) lobectomy remains to be defined. Forty-four consecutive patients with clinical stage I lung cancer underwent lobectomy by the VATS approach (n = 22 patients) or thoracotomy approach (n = 22 patients). Acute pain was quantitated by postoperative narcotic requirements and the need for epidural anesthesia. Long-term QOL was assessed by questioning patients about the presence of chronic chest pain, ongoing limitations in arm or shoulder function, time until return to preoperative activity, and satisfaction with the operation. Patients who underwent VATS lobectomy had significant decreases in both acute and chronic chest pain and time until return to preoperative activity. Patients also had more confidence regarding wound size and their overall impression of the operation. In this series, VATS lobectomy was associated with long-term benefits for the QOL in patients with lung cancer. However, the exact role of this approach should be defined by carefully-designed controlled trials studying long-term survival.

摘要:
Video-assisted thoracoscopic surgery (VATS) has been used recently in the diagnosis and management of thoracic diseases. In this report, VATS experience with 95 cases, focusing on indications, surgical procedures, complications, and failure rates, are reviewed. Over the past 5 years, 95 VATS procedures for diagnostic and therapeutic purposes were performed in 59 men and 36 women. The specific indications for VATS were lung biopsy for undiagnosed diffuse lung disease (48), mediastinal biopsy (12) and cyst (2), pleural effusion (10), empyema (5), pneumothorax and bullous lung disease (6), pericardial effusion (2) and cyst (2), paravertebral abscess (2), solitary pulmonary nodules (3), and thoracic trauma (3). In all patients, postoperative pain was controlled with non-narcotic analgesics and was measured according to the visual analogue scale (VAS). There was no surgical mortality. Postoperative nonfatal complications were seen in seven cases (7.5%). The overall median duration of chest tube drainage was 2.7 days and the mean postoperative hospital stay was 3 days. For diffuse lung disease, a tissue diagnosis was obtained in all the cases. Definitive diagnosis in the patients with undiagnosed pleural effusion was obtained in 90% of cases, and the overall diagnostic rate was 98.5%. The success rate of the therapeutic procedures was 100% after a mean follow-up of 12 months (range, 6–30 months). Conversion to thoracotomy was needed in six cases (6.6%). All patients scored postoperative pain <50% according to the VAS. Video-assisted thoracoscopic surgery should be considered as a procedure of choice, with exceptional results in the following chest diseases: (a) undiagnosed pleural effusions; (b) recurrent, post-traumatic, or complicated spontaneous pneumothorax; (c) stage II empyema; (d) accurate staging of lung cancer; (e) emergency traumatic injuries of the chest; (f) peripheral solitary pulmonary nodule <3 cm; and (g) lung biopsy for pulmonary diffuse disease.

摘要:
Early peritoneal seeding and trocar site metastasis from gallbladder cancer have been reported after laparoscopic cholecystectomy. Nevertheless, the role of laparoscopy in gallbladder cancer remains controversial. Two cases of early recurrence of carcinoma of the gallbladder after laparoscopic cholecystectomy are described. In the first case, the use of a gasless technique did not prevent an early, diffuse peritoneal dissemination of the disease. In the second case, despite the use of a retrieval bag to extract the gallbladder, multiple metastases around the gallbladder bed and local peritoneal seeding developed. These cases demonstrate that factors other than bile spillage, CO2inflation, and the use of a retrieval bag are responsible for early dissemination of gallbladder cancer.

摘要:
For the purpose of prevention of postgastrectomy syndrome and a less invasive and yet curative oncological resection, a purely laparoscopic pyloruspreserving gastrectomy with extraperigastric lymphadenectomy was performed for a patient with early gastric cancer located in the middle third of the stomach. The patient's postoperative course was uneventful. During his postoperative recovery, the patient experienced very little pain and used analgesic medication only one time. This operation appeared to be oncologically adequate. As of the seventh postoperative month, the patient never experienced dumping syndrome or alkaline reflux gastritis. This procedure is technically feasible and an excellent option because of its reduced surgical invasiveness and better postoperative quality of life.
