Determinants of long-term satisfaction after vertical banded gastroplasty   总被引:3,自引:3,他引:0  
Background: The long-term usefulness of vertical banded gastroplasty (VBG) in achieving weight loss is controversial, and adverse effects related to the procedure may attenuate patient satisfaction. Our objective was to evaluate patient satisfaction, and to identify parameters that are related to such satisfaction, 3 to10 years after VBG. Methods: All consecutive patients who underwent VBG in one surgical ward were invited for a follow-up study 3 to 10 years after surgery. Questions relating to symptoms and quality of life were evaluated in a personal interview using a structured questionnaire. Results: Of the 122 patients who underwent VBG from 1986 to 1992, 75 patients were located and agreed to participate in the follow-up study. The average time since surgery was 5.4 ± 1.8 years. The average weight loss was 24.9 ± 12.4%, representing an excess body-weight loss of 58.6 ± 30.4%. Overall, 65% of the patients were satisfied with the results of surgery while 19% expressed dissatisfaction. Significant improvement was seen in respiratory difficulties, ability to perform physical exercise, and mental status. Successful weight loss and the frequency of respiratory difficulties were the only independent parameters associated with patient satisfaction. Although vomiting, gastroesophageal reflux and difficulty in swallowing occurred in over two-thirds of the patients, their presence was not correlated with patient dissatisfaction. Conclusion: Despite the presence of a multitude of adverse effects, the majority of our patients were satisfied with the long-term results of VBG. Successful weight loss and improvement in respiratory difficulties were the major determinants of patient satisfaction.  相似文献

Laparoscopic management of acute small bowel obstruction   总被引:2,自引:2,他引:5  
Background As minimally invasive surgery gains ground, it is entering realms previously considered to be relative contraindications for laparoscopy. We reviewed our experience with the laparoscopic approach to the management of small bowel obstruction (SBO).Methods From December 1997 to November 2002, 65 patients underwent laparoscopic treatment for SBO. The operating surgeon attempted to identify a transitional point between distended and collapsed bowel and then address the obstruction at that point.Results Postoperative adhesions were the cause of the obstruction in 44 patients. Tumor was identified in five cases, hernia in four, bezoar in three, intussusception in three, acute appendicitis and pseudoobstruction in two cases each, and terminal ileitis in one case. The diagnostic accuracy of laparoscopy was 96.9%. Thirty-four patients (52%) were treated by laparoscopy alone. Thirteen patients (20%) required a small target incision for segmental resection. Eighteen operations were converted to formal laparotomy. The mean laparoscopy time was 40 min (range, 25-160). Patients resumed oral intake in 1-3 days. The complication rate was 6.4%. There were two deaths, but none related to laparoscopy. The mean hospital stay was 4.2 days.Conclusions Laparoscopy is a useful minimally invasive technique for the management of acute SBO. It is an excellent diagnostic tool and, in most cases, a therapeutic surgical approach in patients with SBO. However, a significant number of patients will require conversion.Presented in part at the 10th annual congress of the European Association for Endoscopic Surgery (EAES), Lisbon, Portugal, 2-5 June, 2002  相似文献

Background  Laparoscopic Roux-en-Y gastric bypass surgery reportedly has a higher rate of postoperative internal hernias than open bypass surgery. Even with closure of mesenteric defects, hernias occur in up to 9% of cases. To minimize this complication, an antecolic antegastric approach to anastomosis of the Roux limb and gastric pouch has been used. Whereas the retrocolic retrogastric technique creates three mesenteric defects, the antecolic approach produces only two: Petersen’s defect and the jejunojejunostomy. The rate of internal hernias was compared among patients undergoing laparoscopic Roux-en-Y gastric bypass surgery using the retrocolic and antecolic approaches. Methods  The experience of a single surgeon from August 2001 to September 2005 was reviewed. Only Roux-en-Y gastric bypass procedures were included. Patients were followed for a minimum of 18 months postoperatively. The retrocolic approach was used for 274 patients and the antecolic approach for 205 patients. All defects were closed at the time of surgery. With the antecolic approach, Petersen’s defect was closed from the root of the mesentery of the Roux limb and the transverse colon mesentery up to the transverse colon. Results  Of the 274 patients, 7 (2.6%) experienced a symptomatic internal hernia with the retrocolic retrogastric technique. No internal hernias were reported among the 205 patients treated with the antecolic antegastric method. Chi-square analysis showed that an antecolic approach was associated with a decreased rate of internal hernias (p < 0.025). Of 479 patients, 35 (7%) underwent diagnostic laparoscopy without any internal hernia found. Of these patients, 15 were found to have cholelithiasis and subjected to laparoscopic cholecystectomy. Conclusions  The antecolic antegastric approach to laparoscopic Roux-en-Y gastric bypass is associated with fewer postoperative hernias than the retrocolic retrogastric approach. The frequency of hernias using either technique is low if meticulous attention is paid to closure of all mesenteric defects.

INTRODUCTION: There are currently no reports in the literature regarding changes in end-tidal carbon dioxide (ETCO(2)) when the small bowel is deliberately or inadvertently perforated during laparoscopic surgery. The aim of this study was to assess the influence of small bowel perforation during laparoscopy on ETCO(2) in a rat model. MATERIALS AND METHODS: Two groups of Wistar rats (n = 8/group) were anesthetized, tracheostomized, and mechanically ventilated at a fixed tidal volume and respiratory rate. After a stabilization phase of 30 min, CO(2) pneumoperitoneum was established to 5 mmHg in one group and 12 mmHg in the other group, and maintained for 30 min. A small bowel perforation was then created and pneumoperitoneum was reestablished for another 30 min. Blood pressure, heart rate, peak ventilatory pressure, and ETCO(2) were recorded throughout the experiment. RESULTS: No significant changes in blood pressure throughout the experiment were noted in either group. The ventilatory pressure increased in both groups after the induction of pneumoperitoneum. In the 5 mmHg group, there was a modest increase in ETCO(2) following the induction of pneumoperitoneum (from 39.4 +/- 1.9 to 41.1 +/- 1.4, P = 0.014), and a further increase following the small bowel perforation (from 41.1 +/- 1.4 to 42 +/- 0.8, P = 0.007). In the 12 mmHg group, there was no change in ETCO(2) after the induction of pneumoperitoneum; however, there was a substantial increase in ETCO(2) following bowel perforation (35.0 +/- 2.0 to 49.8 +/- 7.1, P = 0.002). CONCLUSIONS: ETCO(2) increases when the small bowel is perforated during CO(2) pneumoperitoneum. This increase seems more substantial under higher pneumoperitoneal pressures. Small bowel injury may enable the diffusion of CO(2) through the bowel mucosa, causing ETCO(2) elevation. Therefore, an abrupt increase in ETCO(2) observed during laparoscopy may indicate small bowel injury.  相似文献

A case of rapidly progressing Hodgkin's lymphoma is described in which two uncommon complications were observed. Perforation of the cecum due to lymphomatous invasion occurred with subsequent cecosigmoid fistula and pelvic abscess.Salmonella paratyphi B septicemia, refractory to all treatment, caused death of the patient approximately 2 years after initial diagnosis. The relevant literature is reviewed and the possible role of impaired function of immunological mechanisms due to both the malignancy and its treatment in exposing the patient to opportunistic infections is discussed. Although the complications in this patient were treated by further radiation therapy, antibiotics and supportive measures, early surgical intervention is probably the treatment of choice for complications of lymphomatous invasion of the gastrointestinal tract, so as to reduce undue exposure to the dangers of septic complications.
Résumé Présentation d'un cas de lymphome type Hodgkin à évolution rapide et avec deux complications inhabituelles: (1) perforation du caecum par infiltration lymphomateuse, avec fistule caeco-sigmoÏdienne et abcès pelvien; (2) septicémie à Salmonella para-B résistant à tout traitement et responsable du décès 2 ans après le diagnostic. La littérature est revue: il est possible que la dépression immunitaire due tant à la tumeur qu'au traitement favorise les infections opportunistes chez ce type de malades. Dans notre cas, les complications ont été traitées par radiothérapie et antibiotiques. Mais l'opération précoce est vraisemblablement le traitement de choix des complications dues à l'atteinte lymphomateuse du tube digestif: elle réduira le danger de complications infectieuses.

Malignant duodenocolic fistula, a rare complication of carcinoma of the hepatic flexure of the colon, may present with bilious diarrhea and feculent vomiting, and is usually associated with severe electrolyte and nutritional depletion. In 2 cases of duodenoenteric fistula caused by recurrence of colonic cancer after right hemicolectomy, the tumor was unresectable. Isolation of the affected intestinal loop, without any attempt at disconnecting it from the duodenum, and diversion of that loop back into the jejunum provided a solution, achieving satisfactory palliation and an improvement in nutritional state.  相似文献

Summary The traumatic mediastinal emphysema occurs along with severe combined injuries. A typical feature is the subcutaneous emphysema as well as crackling sounds and frequently a pneumothorax. The radiography of the chest shows air in the mediastinum surrounding the mediastinal structures. The pleura drainage could be done as an emergency performance in cases of pneumothorax. In cases of an increasing subcutaneous and mediastinal emphysema as well as circulatory failure a cervical mediastinotomy should be carried out. The tracheobronchial tree should be examined bronchoscopically for possible ruptures. Esophagus injuries will be detected by the distribution of a contrast fluid. Even a thoracotomy may be necessary.  相似文献

The mechanism of gastric acid reduction following vagotomy is still unclear: does this reduction result from a decrease in parietal cell mass, or is the reduction just functional? In an attempt to settle the question, we used a litter of puppies, in which rapid multiplication of parietal cells takes place. We performed truncal vagotomy (histologically proven) on 4 puppies, using 3 puppies as a control group. Open gastric biopsies were taken every month from birth uncil 12 months of age. Parietal cells were counted and correlated with age. We found a significant reduction in the parietal cell mass in the vagotomized group during 4 months after delivery. The possible mechanisms explaining this phenomenon, as well as assumed clinical correlation, are discussed.  相似文献

In congenital absence of the anatomic common bile duct, all bile from the liver drains into the gallbladder and thence to the duodenum via the cystic duct. A likely consequence of cholecystectomy then is discontinuity of hepatic drainage, since the gallbladder and cystic duct appear normal, and the anomaly is so rare that it is not considered.  相似文献
