Uncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer

BACKGROUND

Choosing an optimal reconstruction method is pivotal for patients with gastric cancer undergoing distal gastrectomy. The uncut Roux-en-Y reconstruction, a variant of the conventional Roux-en-Y approach (or variant of the Billroth II reconstruction), employs uncut devices to occlude the afferent loop of the jejunum. This modification is designed to mitigate postgastrectomy syndrome and enhance long-term functional outcomes. However, the comparative benefits and potential harms of this approach compared to other reconstruction techniques remain a topic of debate.

OBJECTIVES

To assess the benefits and harms of uncut Roux-en-Y reconstruction after distal gastrectomy in patients with gastric cancer.

SEARCH METHODS

We searched CENTRAL, PubMed, Embase, WanFang Data, China National Knowledge Infrastructure, and clinical trial registries for published and unpublished trials up to November 2023. We also manually reviewed references from relevant systematic reviews identified by our search. We did not impose any language restrictions.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs comparing uncut Roux-en-Y reconstruction versus other reconstructions after distal gastrectomy for gastric cancer. The comparison groups encompassed other reconstructions such as Billroth I, Billroth II (with or without Braun anastomosis), and Roux-en-Y reconstruction.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures. The critical outcomes included health-related quality of life at least six months after surgery, major postoperative complications within 30 days after surgery according to the Clavien-Dindo Classification (grades III to V), anastomotic leakage within 30 days, changes in body weight (kg) at least six months after surgery, and incidence of bile reflux, remnant gastritis, and oesophagitis at least six months after surgery. We used the GRADE approach to evaluate the certainty of the evidence.

MAIN RESULTS

We identified eight trials, including 1167 participants, which contributed data to our meta-analyses. These trials were exclusively conducted in East Asian countries, predominantly in China. The studies varied in the types of uncut devices used, ranging from 2- to 6-row linear staplers to suture lines. The follow-up periods for long-term outcomes spanned from 3 months to 42 months, with most studies focusing on a 6- to 12-month range. We rated the certainty of evidence from low to very low. Uncut Roux-en-Y reconstruction versus Billroth II reconstruction In the realm of surgical complications, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Billroth II reconstruction may make little to no difference to major postoperative complications (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.24 to 4.05; I² = 0%; risk difference (RD) 0.00, 95% CI -0.04 to 0.04; I² = 0%; 2 studies, 282 participants; very low-certainty evidence) and incidence of anastomotic leakage (RR 0.64, 95% CI 0.29 to 1.44; I² not applicable; RD -0.00, 95% CI -0.03 to 0.02; I² = 32%; 3 studies, 615 participants; very low-certainty evidence). We are very uncertain about these results. Focusing on long-term outcomes, low- to very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Billroth II reconstruction may make little to no difference to changes in body weight (mean difference (MD) 0.04 kg, 95% CI -0.84 to 0.92 kg; I² = 0%; 2 studies, 233 participants; low-certainty evidence), may reduce the incidence of bile reflux into the remnant stomach (RR 0.67, 95% CI 0.55 to 0.83; RD -0.29, 95% CI -0.43 to -0.16; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 3 to 7; 1 study, 141 participants; low-certainty evidence), and may have little or no effect on the incidence of remnant gastritis (RR 0.27, 95% CI 0.01 to 5.06; I2 = 78%; RD -0.15, 95% CI -0.23 to -0.07; I2 = 0%; NNTB 7, 95% CI 5 to 15; 2 studies, 265 participants; very low-certainty evidence). No studies reported on quality of life or the incidence of oesophagitis. Uncut Roux-en-Y reconstruction versus Roux-en-Y reconstruction In the realm of surgical complications, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Roux-en-Y reconstruction may make little to no difference to major postoperative complications (RR 4.74, 95% CI 0.23 to 97.08; I² not applicable; RD 0.01, 95% CI -0.02 to 0.04; I² = 0%; 2 studies, 256 participants; very low-certainty evidence) and incidence of anastomotic leakage (RR 0.34, 95% CI 0.05 to 2.08; I² = 0%; RD -0.02, 95% CI -0.06 to 0.02; I² = 0%; 2 studies, 213 participants; very low-certainty evidence). We are very uncertain about these results. Focusing on long-term outcomes, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Roux-en-Y reconstruction may increase the incidence of bile reflux into the remnant stomach (RR 10.74, 95% CI 3.52 to 32.76; RD 0.57, 95% CI 0.43 to 0.71; NNT for an additional harmful outcome (NNTH) 2, 95% CI 2 to 3; 1 study, 108 participants; very low-certainty evidence) and may make little to no difference to the incidence of remnant gastritis (RR 1.18, 95% CI 0.69 to 2.01; I² = 60%; RD 0.03, 95% CI -0.03 to 0.08; I² = 0%; 3 studies, 361 participants; very low-certainty evidence) and incidence of oesophagitis (RR 0.82, 95% CI 0.53 to 1.26; I² = 0%; RD -0.02, 95% CI -0.07 to 0.03; I² = 0%; 3 studies, 361 participants; very low-certainty evidence). We are very uncertain about these results. Data were insufficient to assess the impact on quality of life and changes in body weight.

AUTHORS' CONCLUSIONS

Given the predominance of low- to very low-certainty evidence, this Cochrane review faces challenges in providing definitive clinical guidance. We found the majority of critical outcomes may be comparable between the uncut Roux-en-Y reconstruction and other methods, but we are very uncertain about most of these results. Nevertheless, it indicates that uncut Roux-en-Y reconstruction may reduce the incidence of bile reflux compared to Billroth-II reconstruction, albeit with low certainty. In contrast, compared to Roux-en-Y reconstruction, uncut Roux-en-Y may increase bile reflux incidence, based on very low-certainty evidence. To strengthen the evidence base, further rigorous and long-term trials are needed. Additionally, these studies should explore variations in surgical procedures, particularly regarding uncut devices and methods to prevent recanalisation. Future research may potentially alter the conclusions of this review.

Laparoscopic Nissen Versus Toupet Fundoplication for Short- and Long-Term Treatment of Gastroesophageal Reflux Disease: A Meta-Analysis and Systematic Review

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is the most common standard technique worldwidely for Gastroesophageal reflux disease (GERD). Another type of fundoplication, laparoscopic Toupet fundoplication (LTF), intends to reduce incidence of postoperative complications. A systematic review and meta-analysis are required on short- and long-term outcomes based on randomized controlled trials (RCTs) between LNF and LTF.

METHODS

We searched databases including PubMed, Cochrane, Embase, and Web of Knowledge for RCTs comparing LNF and LTF. Outcomes included postoperative reflux recurrence, postoperative heartburn, dysphagia and postoperative chest pain, inability to belch, gas bloating, satisfaction with intervention, postoperative esophagitis, postoperative DeMeester scores, operating time (min), in-hospital complications, postoperative use of proton pump inhibitors, reoperation rate, postoperative lower oesophageal sphincter (LOS) pressure (mmHg). We assessed data using risk ratios and weighted mean differences in meta-analyses.

RESULTS

Eight eligible RCTs comparing LNF (n = 605) and LTF (n = 607) were identified. There were no significant differences between the LNF and LTF in terms of postoperative reflux recurrence, postoperative heartburn, postoperative chest pain, satisfaction with intervention, reoperation rate in short and long term, in-hospital complications, esophagitis in short term, and gas bloating, postoperative DeMeester scores, postoperative use of proton pump inhibitors, reoperation rate in long term. LTF had lower LOS pressure (mmHg), fewer postoperative dysphagia and inability to belch in short and long term and gas bloating in short term compared to LNF.

CONCLUSION

LTF were equally effective at controlling reflux symptoms and improving the quality of life, but with lower rate of complications compared to LNF. We concluded that LTF surgical treatment was superior for over 16 years old patients with typical symptoms of GERD and without upper abdominal surgical history upon high-level evidence of evidence-based medicine.

Meta-analysis of Long-term De Novo Acid Reflux-Related Outcomes Following Sleeve Gastrectomy: Evidence Against the Need for Routine Postoperative Endoscopic Surveillance

OBJECTIVES

To evaluate the incidence of long-term de novo acid reflux-related complications following sleeve gastrectomy (SG) to determine whether routine postoperative surveillance endoscopy is necessary.

METHODS

A systematic search of Medline, Embase, CINAHL, CENTRAL, the Web of Science, and bibliographic reference lists was conducted. A proportion meta-analysis model was constructed to quantify the risk of the de novo gastro-oesophageal reflux disease (GORD), oesophagitis, and Barrett's oesophagus (BE) at least 4 years after SG. Random-effects modelling was applied to calculate pooled outcome data.

RESULTS

Thirty-two observational studies were included reporting a total of 7904 patients who underwent primary SG and were followed up for at least 4 years. The median follow-up period was 60 months (48-132). Preoperative acid-reflux symptoms existed in 19.1% ± 15.1% of the patients. The risk of development of de novo GORD, oesophagitis, and BE after SG was 24.8% (95% CI 18.6-31.0%), 27.9% (95% CI 17.7-38.1%), and 6.7% (95% CI 3.7-9.7%), respectively. The between-study heterogeneity was significant in all outcome syntheses. It was suspected that several of the included studies have not reported BE and oesophagitis because such events might not have happened in their cohorts.

CONCLUSIONS

Long-term risk of de novo GORD after SG seems to be comparable with those of the general population which questions the merit of surveillance endoscopy after SG in asymptomatic patients. De novo BE and oesophagitis after SG have not been reported by most of the available studies which may lead to overestimation of the rates of both outcomes in any evidence synthesis. We recommend endoscopic surveillance for symptomatic patients only.

Association between the body mass index, waist circumference, and body fat percentage with erosive esophagitis in adults with obesity after sleeve gastrectomy

Background: High anthropometric indexes before sleeve gastrectomy (SG) are associated with an increased risk of erosive esophagitis (EE) in bariatric surgery candidates. Reasons that explain how these indexes influence the development of esophageal pathology after surgery remains unclear. Objectives: To assess the association between the body mass index (BMI), waist circumference (WC), and body fat percentage (BFP) with the development of EE in adults with obesity three months after SG. Setting: Clínica Avendaño, Lima, Peru. Methods: Retrospective cohort using a database including adults with obesity who underwent SG during 2017-2020. All the patients included had an endoscopy before and after the surgery. Sociodemographic, clinical and laboratory characteristics were compared according to BMI, WC and BFP, as well as by the development of de novo esophagitis. The association was evaluated by crude and adjusted generalized linear models with the log-Poisson family. Results: From a total of 106 patients, 23 (21.7%) developed EE. We did not find significant differences in sociodemographic, clinical and laboratory characteristics between patients with de novo EE compared to those who did not develop EE. After adjustment, BMI (aRR = 0.59, 95% CI = 0.18-1.40), BFP (aRR = 0.41, 95% CI = 0.15-1.19) and WC (aRR = 0.91, 95% CI = 0.69-1.16) were not associated with the development of EE three months post SG. Conclusions: We found no association between preoperative anthropometric indexes and the development of de novo EE; therefore, morbid obesity should not be a criterion to exclude the patients to undergo SG as primary surgery because of the risk of developing EE.

Fifteen Years after Sleeve Gastrectomy: Gastroscopies, Manometries, and 24-h pH-Metries in a Long-Term Follow-Up: A Multicenter Study

INTRODUCTION

Sleeve gastrectomy (SG) is the most common bariatric operation with over 340,000 procedures per year. There are only few studies presenting follow-up results >10 years in the literature today. The aim of this study was the objective evaluation of long-term outcomes of at least 15 years after SG in non-converted patients.

METHODS

This study (multicenter cross-sectional; university-hospital based) includes all non-converted patients with primary SG before December 2005 at participating bariatric centers. The following methods were used: gastroscopy, esophageal manometry, 24-h pH-metry, and Gastrointestinal Quality of Life Index (GIQLI).

RESULTS

After removing converted patients, patients with bariatric procedures before SG, and deceased patients from the cohort, 20 of 53 participants have met the inclusion criteria. Of this group, 55% are suffering from symptomatic gastroesophageal reflux disease (GERD); 45% are without GERD. Esophagitis, hiatal hernias, Barrett's esophagus, and enlarged sleeves were found in 44%, 50%, 13%, and 69% of patients during gastroscopy. Mean lower esophageal sphincter pressure was normal at 20.2 ± 14.1 mm Hg during manometry. Reflux activity in 24 h, number of refluxes, and DeMeester score were increased at 12.9 ± 9.7%, 98.0 ± 80.8, and 55.3 ± 36.3 during 24-h pH-metry. Patients with GERD scored significantly lower in the GIQLI than patients without GERD: 107.6 ± 18.4 versus 127.6 ± 14.4 (p = 0.04).

DISCUSSION/CONCLUSION

Fifteen years after primary SG, objective testing has shown that GERD, esophagitis, and Barrett's esophagus are major issues for these patients. Surveillance endoscopies at 5-year intervals in all SG patients and 3-year intervals in patients with Barrett's esophagus are recommended.

Gastroesophageal Reflux Disease, Esophagitis, and Barrett's Esophagus 3 to 4 Years Post Sleeve Gastrectomy

BACKGROUND

Sleeve gastrectomy (SG) has become the most popular bariatric procedure worldwide. However, SG is associated with de novo gastroesophageal reflux (GERD) and esophagitis, with concerns for progression into Barrett's esophagus (BE). The purpose of this study is to assess the clinical and endoscopic progression of GERD, esophagitis, and BE 3 to 4 years after SG.

METHODS

Fifty-eight patients (pts) were assessed with endoscopy preoperative and at 3 to 4 years post SG, representing 44.9% follow-up. Endoscopy was offered to all SG pts regardless of symptoms. Outcomes including percent total weight loss (%TWL), PPI use, esophagitis progression, de novo reflux, and BE formation.

RESULTS

At post-op follow-up, the %TWL was 23%. The average BMI dropped from 49.07 to 37.5. De novo reflux developed in 13 pts (30.9%). Of the 16 pts with GERD pre-op, 37.5% improved, 25% had stable disease, and 37.5% had worsening symptoms. The rate of esophagitis nearly doubled from 37.9% pre-op to 70.6% post-op. A majority of post-op pts had mild esophagitis (87.8%), with 12.1% with LA classes C and D. Asymptomatic esophagitis was found in 68.2% of post-op pts. The incidence of BE was 12.7% post-op, with de novo BE developing in 4 pts, representing 7.2%.

CONCLUSION

SG is associated with increased rates of asymptomatic esophagitis and de novo reflux at 3 to 4 years post-op. De novo BE was detected as well, highlighting the importance of post-op screening. The majority of pts with GERD pre-op have stable disease or improve.

Transoral incisionless fundoplication: 2-year results from the prospective multicenter U.S. study

The aim of this study was to assess prospectively 2-year outcomes of transoral incisionless fundoplication (TIF) in a multicenter setting. A 14-center U.S. registry was designed to evaluate the effects of the TIF 2.0 procedure on chronic gastroesophageal reflux disease (GERD) in over 100 patients. Primary outcome was symptom assessment. Secondary outcomes were proton pump inhibitor (PPI) use, degree of esophagitis, safety, and changes in esophageal acid exposure. One hundred twenty-seven patients underwent TIF between January 2010 and April 2011, 19 (15%) of whom were lost to follow-up. Eight patients undergoing revisional surgery were included, as failures, in the 108 remaining patients. No serious adverse events were reported. GERD Health-related Quality of Life and regurgitation scores improved by 50 per cent or greater in 63 of 96 (66%) and 62 of 88 (70%) patients who had elevated preoperative scores. The Reflux Symptom Index score normalized in 53 of 82 (65%) patients. Daily PPI use decreased from 91 to 29 per cent. In patients amenable to postoperative testing, esophagitis healed in 12 of 16 (75%) and esophageal acid exposure normalized in eight of 14 (57%). TIF safely achieved sustained symptomatic control over a 2-year period in two-thirds of patients with a virtual absence of de novo side effects.

Short and long-term results of laparoscopic total fundic wrap (Nissen) or semifundoplication (Toupet) for gastroesophageal reflux disease

INTRODUCTION

Gastroesophageal reflux disease (GERD) is a common upper GIT disorder. The choice of surgical management options is debatable between laparoscopic Nissen fundoplication (LNF) and Toupet fundoplication (LTF) especially in cases with esophageal dysmotility. PATIENTS AND METHODS/AIMS: 102 patients with chronic GERD divided into 2 groups. Group (1): Patients with good peristalsis (n=70) done LNF. Group (2): Patients with poor peristalsis (n=32) patients done LTF to compare the outcome. They were included in this study. They subjected to clinical, radiological and esophageal motility investigations.

RESULTS

In postoperative period, Recurrent of heartburn, dysphagia and abdominal distension were found in 5.71% , 14.28% and 27.14% post LNF and in 9.37%, 15.62% and 15.62% post LTF respectively. Pre operative LESP was 10.16±5.4 mmHg in LNF & 9.56±3.51 mmHg in LTF group increased to 20.7±7.84 mmHg early after LNF (p<0.0001) & 15.26±6.47 early after LTF (p = 0.0002). Esophageal 24hrs pH metry in early and late post operative showed a significant improvement of % reflux (p < 0.001) in both groups.

CONCLUSION

Toupet fundoplication became the procedure of choice of cases with esophageal dysmotility due to its ease of application, patient satisfaction, low dysphagia rate and low levels of abdominal distension.

[Non-neoplastic esophageal stenosis: not always so benign]

Esophageal intramural pseudodiverticulosis is a rare pathology whose etiology is unknown, but which is frequently associated with three highly prevalent entities: esophageal reflux disease, esophageal candidosis and alcoholic esophagitis. With conservative treatment the course of these pathologies is usually benign. However, some severe cases are resistant to conservative treatment and may require more aggressive management. We here present the case of patient suffering from a severe esophagitis complicated by chronic mediastinitis with life-threatening repercussions, requiring esophagectomy as treatment.

Omitting of bougie appears to be safe for the performance of the fundal wrap at laparoscopic Nissen fundoplication

AIM

Some operative techniques in fundoplication seem to increase the incidence of obstructive symptoms. Some authors believe that using intraesophageal bougie and preparing a short and floppy valve in laparoscopic Nissen fundoplication will help to decrease any possible tight crus repair and wrap and so it is effective to decrease the prevalence of postoperative dysphagia. The aim of this study is to show that there is no absolute benefit of routine insertion of a bougie during laparoscopic Nissen fundoplication in relation to post-operative dysphagia.

METHODS

All patients who underwent laparoscopic Nissen fundoplication by a single surgeon between January 2001 and August 2011 were reviewed retrospectively. Esophageal bougie intubation was performed in none of the 154 patients. The operation technique, the duration of the operation, hospital stay and the improvement of the symptoms were assessed. The patients who had esophagitis with Barrett's esophagus and who had hiatal hernia that could not get benefit from medical therapy, were selected for the surgery. Laparoscopic Nissen fundoplication with cruroraphy were done in all patients.

RESULTS

Ninety-six of the patients were female and 58 were male. The mean symptom duration was 3.6±0.6 years. The only complication was dysphagia. In eighth week, dysphagia resolved in all patients.

CONCLUSION

Laparoscopic Nissen fundoplication can be safely performed without the routine use of an esophageal bougie and it does not increase the postoperative dysphagia rate.

The vascularization pattern of the colon and surgical decision in esophageal reconstruction with colon. A selective SMA and IMA arteriographic study

INTRODUCTION

No matter the reconstructive technique, the fundamental concepts in visceral reconstruction have as main grounds the mandatory vascular support for the graft replacement. Individual vascular particularities can influence or even oblige the surgeon to choose a certain procedure. This is why the vascularization is beyond doubt the dominant factor in mobilizing the colon for reconstruction.

MATERIAL AND METHOD

Our arteriographic study entails an investigation upon the vascularization pattern of the two main sources that participate in the arterial irrigation of the colon via the emerging vessels: superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). We did not consider certain patients upon a specific criterion; also, we did not exclude any patients due to various reasons. We took into account 49 patients as study group, all of them having registered into the clinic for a reconstructive technique, throughout the years from 2000 to 2010. From 1981 to 2012 there have been 187 reconstructive techniques performed due to post caustic pathology. From a total of 49 patients, 11 had suffered major abdominal surgeries, 5 of which had had unsuccessful reconstructive attempts.

RESULTS

Out of the 49 patients on whom we have performed the exploration, arteriography showed a favorable situation for reconstruction in 31 of them. In the other 18 patients anomalies or atypical distributions were identified, in 5 of the SMA and in 13 of the IMA, respectively. Operative decision was modified in 22 patients. One important thing to note from the point of view of the segment to be moved: we had no graft necrosis in patients with preoperative arteriographic examination.

CONCLUSIONS

Due to the need for good mobilization, arterial ligations should be adjusted and modified depending on the particular vascular distribution, to maintain a sufficient blood flow in the marginal artery, in order to reach the colic sections and the straight arteries near them.

Acute diffuse phlegmonous esophagogastritis: a case report

Acute phlegmonous infection of the gastrointestinal tract is characterized by purulent inflammation of the submucosa and muscular layer with sparing of the mucosa. The authors report a rare case of acute diffuse phlegmonous esophagogastritis, which was well diagnosed based on the typical chest computed tomographic (CT) findings and was successfully treated. A 48-yr-old man presented with left chest pain and dyspnea for three days. Chest radiograph on admission showed mediastinal widening and bilateral pleural effusion. The patient became febrile and the amount of left pleural effusion is increased on follow-up chest radiograph. Left closed thoracostomy was performed with pus drainage. A CT diagnosis of acute phlegmonous esophagogastritis was suggested and a surgery was decided due to worsening of clinical condition of the patient and radiologic findings. Esophageal myotomies were performed and the submucosal layer was filled with thick, cheesy materials. The patient was successfully discharged with no postoperative complication.

[Acute injuries to the upper gastrointestinal tract in patients with multiple cerebral arterial aneurysms]

The paper describes a case of multiple cerebral arterial aneurysms in a patient with prior subarachnoidal hemorrhage, who developed postoperative acute upper gastrointestinal tract (GIT) lesion manifesting itself as bleeding and requiring multiple endoscopic treatment procedures and eventually a direct surgical intervention. The susceptibility of patients with cerebral pathology to upper GIT lesions and methods of their therapy and prevention are discussed.

Autoimmune esophagitis: IgG4-related tumors of the esophagus

We present a case of a 23-year-old gentleman who presented with dysphagia, weight loss, and recurrent esophageal strictures requiring multiple dilatations. An endoscopic ultrasound with esophagogastroduodenoscopy revealed a mass present in the distal esophagus. Fine needle aspiration suggested that the mass in the lower esophagus resembled a gastrointestinal stromal tumor. After surgical resection, final pathologic analysis revealed that the tumor was comprised of benign-appearing fibroinflammatory cells with an increase and predominance of IgG4-positive plasma cells. The microscopic appearance was consistent with a benign condition as a result of an IgG4-related process. He did not, however, have any other symptoms indicative of systemic autoimmune disease or connective tissue disorders. We present the pre-operative imaging, operative management, pathologic diagnosis, and literature review of this rare condition and the first known report of autoimmune esophagitis as part of the IgG4 spectrum of diseases.

Gastric tube interposition for corrosive esophagitis associated with pyloric stenosis

Corrosive esophagitis, caused by swallowing corrosive acid or alkali, results in cicatricial stricture of the esophagus. The stricture is often accompanied by pyloric stenosis because strong acids act synergistically with gastric juice. Resection of both the esophagus and stomach is usually necessary, and the colon or jejunum is used as an esophageal substitute. We describe how we successfully treated corrosive esophagitis associated with pyloric stenosis, by performing gastric tube interposition for the esophageal reconstruction. After resecting the injured distal part of the stomach, we pulled the pedunculated gastric tube up to the cervix after anastomosis to the jejunal limb in a Roux-en-Y fashion. This reconstruction procedure prevented excessive organ sacrifice and was minimally invasive. Thus, esophageal reconstruction by interposition using a pedunculated gastric tube can be used effectively to treat corrosive esophagitis associated with pyloric stenosis.

[Late complications of a skin oesophagoplasty realized 45 years before: an historical case]

We report the case of a patient operated for the late complications of a skin-lined tube reconstruction of the esophagus performed 45 years ago. We recall the historical interest of this method for total esophageal reconstruction and emphasize the fact that it can still be a solution of last resort when intestinal tubes are no longer available.

Surgical management of upper gastrointestinal and small bowel Crohn's disease

Burill Crohn's convincing description of the disease that now carries his name conceived of the illness as arising exclusively from the terminal ileum, involving other sites only secondarily. As a result, he took the condition to be curable by an adequate operative resection. The current concept is that Crohn's disease may affect any segment of the gastrointestinal tract. The practical implication of this change in thinking is the need to conserve bowel when weighing medical and surgical options for each child. Operations should be used to treat complications of the disease. Absolute indications for the surgery are uncommon and include perforation, bleeding, and refractory obstruction. The margins of resection need only include a short amount of grossly normal intestine. Strictureplasty to relieve obstruction without resection should be done when applicable. Maintenance medication after an operation to limit recurrence or recrudescence is frequently advocated.

Expression pattern of squamous cell carcinoma antigen in oesophageal dysplasia and squamous cell carcinoma

The aim of the present study was to evaluate the tissue expression of squamous cell carcinoma antigen (SCCA) in oesophageal dysplasia and squamous cell carcinoma (SCC) with reference to its clinico-pathologic and prognostic significance. Immunohistochemistry using SCCA polyclonal antibody was performed on SCCs from 61 surgical oesophagectomies. Fifteen cases of low-grade dysplasia (LGD) and 37 non-coexistent high-grade dysplasia (HGD) were also sampled from these materials, together with sixteen chronic cases of oesophagitis. SCCA immunoreactivity was present in the maturative compartments of all normal epithelia and oesophagitis. LGDs showed no SCCA immunoreactivity in the dysplastic proliferative component but only in the superficial normal layers. In 94.6% of HGDs, no SCCA immunoreactivity was detected throughout the thickness of the epithelium. In SCCs, SCCA expression higher than 25% was found in 54% of cases. SCCA positivity showed an inverse correlation with histological grade, whereas no statistically significant correlation was found with TNM classifications, stage, or survival. SCCA is not expressed in early oesophageal carcinogenesis but, in SCC, it represents an indicator of histologic differentiation. In differentiated SCC, SCCA may represent a negative factor for cancer invasiveness, through inhibition of proteases.

Esophagotracheal fistula caused by gastroesophageal reflux 9 years after esophagectomy

Fistula between digestive tract and airway is one of the complications after esophagectomy with lymph node dissection. A case of esophagotracheal fistula secondary to esophagitis 9 years after esophagectomy and gastric pull-up for treatment of esophageal carcinoma is described. It was successfully treated with transposition of a pedicled pectoralis major muscle flap.

Laparoscopic Conversion of an Omega in a Roux-en-y Reconstruction After Mini-invasive Total Gastrectomy for Cancer

INTRODUCTION

Few cases of laparoscopic total gastrectomy have been published. Reconstruction of the digestive tract was generally accomplished with a Roux-en-y esophagojejunal mechanical anastomosis. Here we report the first 2 cases of laparoscopic conversion of an omega in a Roux-en-y reconstruction due to the occurrence of a severe alkaline esophagitis after mini-invasive total gastrectomy for cancer.

MATERIALS AND METHODS

Two male patients presented in 2004. One year prior, at another facility, they had undergone laparoscopic total gastrectomy for cancer, with reconstruction of digestive tract by means of an esophagojejeunostomy with a jejunal loop and Braun's side-to-side enteroanastomosis. They complained of daily symptoms of nausea, regurgitation, heartburn, and early postprandial fullness with reduction of appetite and weight loss of almost 15 kg. Instrumental examination diagnosed alkaline esophagitis. Intervention was performed via laparoscopic approach and the digestive reconstruction was reconfigured in a Roux-en-y type with a proximal limb of almost 60 cm.

RESULTS

Operative time was 135 to 180 minutes. No postoperative complications occurred. After 1-year follow-up, symptoms resolution and esophagitis healing have been observed in both patients.

CONCLUSIONS

Laparoscopic gastrectomy is gaining wide acceptance. In our opinion, a standardization of the technique is necessary: we believe Roux-en-y should be considered the preferred reconstruction route ensuring the best protection of the esophagus from alkaline reflux.

Non stenotic food impaction due to eosinophilic esophagitis: a potential surgical emergency

AIM

Eosinophilic esophagitis (EoE) is an emergent condition in which a mucosal infiltrate of > 20 eosinophils per high power microscopic field is accompanied by motor disturbances that may cause food impaction in the absence of esophageal stricture. We report a series of such cases to point out the potential involvement of pediatric surgeons in diagnosis and treatment. Furthermore, data on the motor function of the esophagus investigated manometrically is included.

MATERIAL AND METHODS

Thirteen patients with EoE were referred to our emergency room for acute food bolus impaction. Their median age at diagnosis was 12 years (range 7.6-14.4). History of allergy, endoscopy with biopsy and esophageal function (24-h combined ambulatory manometry with simultaneous pH-metry) were investigated.

RESULTS

In 7 patients emergency endoscopic extraction of the impacted bolus was necessary. Allergic tests were positive in eight patients. The pH probe showed gastroesophageal reflux in two cases. Upon endoscopy, typical features of EoE (esophageal trachealization and whitish papular exudates) were found. Ambulatory 24-h manometry revealed abnormal motility of the distal esophagus with strikingly high amplitudes (> 150 mmHg) and long duration (> 7 sec) of the waves, particularly during the night. Six patients responded rapidly to steroids and/or antiallergic treatment. The remaining patients had a good outcome with dietary treatment alone.

CONCLUSIONS

EoE is an emergent condition that may involve the pediatric surgeon in both the diagnosis and treatment. Typical endoscopic findings and biopsy are required for proper diagnosis. Ambulatory manometry reveals a marked propulsive dysfunction that explains impaction. This dysfunction is reversible, since the symptoms usually disappear with steroids or antiallergic treatment.

Psychological effects of repeated general anesthesia in children

BACKGROUND

Although methods for reducing preoperative anxiety have been a major interest of pediatric anesthesiologists, there are no reports of the effects of repeated anesthesia on psychological development of children.

METHODS

To determine the overall effect of multiple anesthetics on the psychology of children, we undertook to compare the children undergoing repeated anesthesia (Group S) for the treatment of corrosive esophagitis with a control group (Group C) with chronic renal disease and frequent hospital admissions. Psychological tests and diagnosis of children Group S (n = 23) were compared prospectively with Group C (n = 20). All children had been appropriately treated over the previous 5 years and 50% of patients in Group C had general anesthesia once and those in Group S underwent at least 5 GAs. Parents completed a child behavior checklist (CBCL) and Marital Conflict Questionnaire; the children were evaluated by a child psychiatrist using DSM-IV criteria and completed the Child Depression Inventory (CDI).

RESULTS

The children in Group S underwent a total of 251 (11 +/- 7) GAs over 4-60 months. The incidence of psychopathology was nine and 10 children in groups S and C, respectively. The CBCL and CDI scores were parallel with a psychiatric diagnosis. Marital conflict scores were higher in Group S.

CONCLUSIONS

Both chronic disease states affect psychology of children. Repeated anesthesia in addition to chronic disease does not seem to disturb the child's psychological health further when tentative and precautious approach modalities are undertaken.

Free jejunal intrathoracic graft after esophageal replacement failure

We present the case of a 24 year old man who suffered from severe chronic esophagitis and an esophageal stricture. He was managed by gastric pull-up but complicated by leakage of the anastomosis. Subsequent sophageasurgical treatment with free jejunal graft was performed and the rationale for the technique selected is discussed.

A long-term comparison of plication configurations for endoluminal gastroplication: circumferential versus helical

GOALS

To determine the long-term efficacy of endoluminal gastroplication (ELGP) and the most effective plication configuration.

BACKGROUND

Endoluminal gastroplication is an intriguing therapy for gastroesophageal reflux disease. We conducted a retrospective review of a prospective experience of patient cohorts comparing outcomes of the circumferential and helical plication patterns.

STUDY

Twenty patients underwent ELGP, with 9 receiving the circumferential (Group 1) and 11 the helical pattern (Group 2). Manometry, endoscopy, and 24-hour pH monitoring were performed at baseline and at 6 months. Symptom scores and medication usage were assessed at baseline, 1, 3, 6, 12, and 18 months.

RESULTS

Both groups did not differ significantly from each other with respect to symptom improvement, medication usage, or other variables measured. At 6 months, symptom scores, histamine-2 receptor antagonist (H2RA), proton pump inhibitor usage, and hernia size decreased significantly. No other parameter showed a significant change. At the 18-month follow-up, symptom scores and H2RA usage decreased significantly.

CONCLUSION

ELGP improves heartburn and regurgitation scores at 18 months. Our study suggests that there is no benefit to additional plications when using the helical pattern.

[Results of laparoscopic antireflux surgery at five years and beyond]

Laparoscopic antireflux surgery was first introduced in 1991. As with any new technique, there was a learning curve during which surgeons had a unique opportunity to prospectively document the evolution of the technique and its results. We have regularly assessed our results and conducted randomised prospective studies with the aim of obtaining solid long-term outcome data. We now have at least 5 years of follow-up for two groups of patients. Group I consists of the first 178 patients who underwent fundoplicature, i.e. during the learning curve. Group II consists of 107 patients who were enrolled in a randomised trial comparing total fundoplicature with anterior partial fundoplication. The re-operation rate was 15% in Group I and only 6% in Group II. Overall, about 85% of patients were free of reflux symptoms 5-8 years after fundoplication, indicating that laparoscopic surgery provides a durable benefit in the vast majority of patients.

[Esophageal resection for non-specific esophageal motility disorder]

A 47-year-old patient presented with a history of dysphagia for solid food for almost 10 years and weight loss of more than 50 kg. Non-resecting surgical as well as endoscopic procedures (laparoscopic cardiomyotomy with secondary antireflux operations, balloon dilation, Botulinum-toxin injection) were without success. A barium esophagogram showed a confinement of the distal esophagus with a filiform passage of the contrast medium and undigested food in the prestenotic dilated esophageal corpus. Manometry displayed a hypertensive lower esophageal sphincter with a resting pressure of 43.8 mmHg - although completely relaxing. The tubular esophagus was aperistaltic with 100 % simultaneous and repetitive contractions. As all attempts of previous therapy had failed, a transhiatal esophagectomy with gastric pull-up and cervical esophagogastrostomy ensued. Neuropathological examination of the esophagus showed that degeneration of the myenteric plexus was not severely involved, whereas inflammatory and fibrotic changes were obvious. Esophageal resection provided the only chance of a long-term benefit for our patient with relief of dysphagia.

Fallbericht zur Differenzialdiagnose der gastroösophagealen Refluxkrankheit: die eosinophile Ösophagitis

We report on a 22-year-old man with dysphagia and repeated bolus impaction in the esophagus for 10 years. Bolus impactions were frequently mobilised using an endoscope. At endoscopy, esophagitis IV degrees was described. After treatment with omeprazol there was no improvement. The patient was submitted to our hospital for fundoplication. pH-metry demonstrated an increased reflux. At endoscopy of the esophagus, we found red stripes which did not show the typical appearance of erosions. Manometry and X-ray films of the esophagus did not reveal any pathological findings. In combination with anamnesis, symptoms, and endoscopy, the diagnosis of eosinophilic esophagitis was documented by histology. After administration of oral corticosteroids a rapid improvement of the clinical symptoms was observed. The diagnosis of eosinophilic esophagitis should be kept in mind in patients with chronic symptoms of gastroesophageal reflux persisting despite medical therapy, pathological pH-metry and repeated bolus impactions.

Laparoscopic Nissen fundoplication in a community hospital: analysis of 202 patients

We analyzed 202 patients undergoing Laparoscopic Nissen fundoplication. One hundred and three patients (90.6%) had typical reflux symptoms. Hiatal hernias were present in 84.6%. Most patients had erosive esophagitis; sixty-four patients (31.6%) had strictures. Complications occurred in 38 patients (18.8%), with major complications in 15 patients (7.4%). Major complications included bleeding in six, two requiring transfusion, slipped Nissen in three, pneumothorax in two, and esophageal leak in two patients. Eleven patients had postoperative dysphagia that responded to dilation therapy within three months. There was no mortality.

Idiopathic eosinophilic oesophagitis: atypical presentation of a rare disease

A 72 year-old man presented severe dysphagia and weight loss of recent onset. Repeated oesophageal endoscopy and biopsies with macroforceps were normal. Oesophageal manometry disclosed features compatible with achalasia. Oesophageal EUS endoscopy localized an infiltrating process between muscular layers of the oesophageal wall and CT scan delimited a circular thickening in the inferior part of the oesophagus. Because of severe clinical presentation mimicking a possible oesophageal neoplasm like a lymphoma, partial oesophagectomy was performed and revealed eosinophilic oesophagitis. This unusual presentation emphasizes that idiopathic eosinophilic oesophagitis must be proposed in the differential diagnosis of dysphagia, even in old patient without apparent oesophageal lesion at endoscopy.

Isolated oesophageal involvement of Crohn's disease

A 31-year-old male was admitted with complaints of dysphagia and odynophagia. An upper gastrointestinal tract series revealed inflammatory changes in the mid and distal oesophagus with intramural extravasation of the barium. An upper endoscopy showed multiple ulcerations and inflammation. The patient developed a large stricture with no response to serial endoscopic dilations and a surgical resection of the oesophagus was required. Gross examination of the surgical specimen revealed transmural inflammation, deep ulcerations and non-necrotizing epithelioid cell granuloma. All these pathological findings were characteristic of Crohn's disease of the oesophagus. After 36 months of follow-up there has been no recurrence of symptoms or of other sites of involvement.

[Surgery for disease of the esophagus. 8. Corrosive esophagitis]

After the ingestion of caustic substances, not only the esophagus but also the gastrointestinal tract is injured. Severe caustic upper gastrointestinal tract injuries are associated with high mortality and morbidity rates when mediastinitis, chemical peritonitis, or perforation of the gastrointestinal tract occurs. Perforation may occur in the late phase, especially with the ingestion of alkaline solution, because the inflammation invades more deeply with the continuous release of OH-after coming into contact with protein. Therefore care must be taken in the estimation of the extent of inflammation after the ingestion of caustic alkaline solution. There are on established indications for surgery in acute-phase corrosive esophagitis. At present, we determine the indications for surgery based on blood gas examination, endoscopy, and computed tomography (CT). Blood gas examination is used to diagnose the systemic status. Endoscopy reveals corrosive changes with mucosal injury, while CT reveals the presence of mediastinitis, chemical peritonitis, and gastrointestinal tract perforation in the acute phase. Patients in the acute phase first undergo limited resection of the injured organs without reconstruction, with secondary esophageal reconstruction performed subsequently. This paper reports on our successful experience in the early surgical treatment of patients who had severe tissue injury after the ingestion of caustic substances. Patient prognosis was good using our surgical technique.

[Techniques and outcomes of laparoscopic surgery in gastroesophageal reflux disease]

BACKGROUND

The purpose of this study is to report personal experience in laparoscopic antireflux surgery and to analyze the clinical and functional outcomes of this procedure, also in relation to the different techniques used.

METHODS

From 1996 to 2000, 20 patients with gastroesophageal reflux disease associated with hiatal hernia underwent laparoscopic surgery. The indication for surgery was failure of long-term medical therapy. All patients had severe acid reflux on 24 hrs-pH monitoring, endoscopic evidence of esophagitis and hiatal hernia, and defective lower esophageal sphincter. A Nissen fundoplication was performed in 13 patients with normal esophageal body motility, and a 270 degrees posterior fundoplication in seven patients with low esophageal motility.

RESULTS

Mortality and conversion rate were 0. Mean operative time was 135 min and mean postoperative hospital stay 5 days. Operative morbidity was 15%. All the patients were completely cured of reflux symptoms; transient mild postoperative dysphagia occurred in two patients (10%). There was a significantly improvement of the results in postoperative esophageal manometry and 24 hrs-pH monitoring.

CONCLUSIONS

This preliminary experience suggests that laparoscopic surgery represents a safe and effective procedure for the treatment of gastroesophageal reflux disease. Precise selection of patients and adequate surgical technique are essential.

Treatment of azole-resistant oropharyngeal candidiasis with topical amphotericin B

OBJECTIVE

To report a case of successful treatment of azole-refractory oropharyngeal candidiasis with topical amphotericin B.

CASE SUMMARY

A 30-year-old white woman presented with recurrent oral thrush. The patient had been exposed to azole antifungals for >20 years, and in vitro susceptibility tests revealed class resistance. The patient started taking amphotericin B 100 mg oral suspension swish-and-spit 4 times daily. After 4 weeks of topical amphotericin B treatment, the patient reported significant symptomatic improvement. The oral candidiasis worsened following a course of oral antibiotics, but improved once the antibiotic was discontinued and after receiving amphotericin B swish-and-swallow for 4 additional weeks.

DISCUSSION

Current Infectious Diseases Society of America guidelines include topical amphotericin B as a potentially effective option for the treatment of oropharyngeal candidiasis. There is limited evidence to support this recommendation. Besides lack of data, an appropriate dosing regimen and consistent means of product formulation need to be determined.

CONCLUSIONS

This report demonstrates the potential role for topical amphotericin B in the treatment of azole-refractory oral candidiasis. Double-blind, randomized, controlled trials are needed to define dosing, efficacy, administration, and long-term safety of oral amphotericin B.

[Severity of anemia and operative morbidity and mortality. Report on 3 clinical cases in Jehovah's Witnesses and review of the literature]

It has been reported that patients who refuse blood transfusions, such as Jehovah's witnesses, can undergo major surgery. In a review of the literature, however, we critically examined the severity of anaemia in relation to operative mortality and morbidity rates. We report three cases of Jehovah's witnesses who underwent major surgery and presented complication during the postoperative period. Case 1: a 50-year-old man with oesophageal achalasia who underwent Heller's myotomy and Nissen's fundoplication. The postoperative period was complicated by massive haemorrhage and the patient was reoperated on postoperative day 1. After four years, he underwent total oesophagectomy because of severe chronic oesophagitis. On postoperative day 13 the patient suffered anteroseptal myocardial ischaemia, which was treated with medical therapy. Case 2: a 40-year-old man, admitted for ulcerative rectocolitis, who underwent total colectomy. On postoperative day 1 he presented massive haemorrhage and shock. He was reoperated and the postoperative period was complicated by myocardial ischaemia, renal failure and an enterocutaneous fistula. Case 3: a 65-year-old woman with ulcerative rectocolitis who underwent total colectomy and a temporary ileostomy. She suffered venous thrombosis of the lower limbs and pulmonary oedema. The patient died 14 months after surgery as a result of massive haemolysis by cryoagglutinins and cardiac arrest.

Esophageal replacement using the colon: a 15-year review

Colonic interposition is a treatment option in childhood when esophageal replacement (ER) is necessary. We reviewed 18 children who underwent ER by colon between 1984 and 1999. There were 5 with esophageal atresia and 13 with corrosive esophagitis; 15 had long-term follow-up (mean 38 months). Three procedures were performed by the Waterston technique and 12 by the retrosternal technique. ER was completed in a single stage in all but 1 patient. Pyloroplasty or antireflux surgery were not done routinely during colonic interposition. As early complications, we observed 11 cervical leaks and 2 pulmonary problems. As late complications, there were 4 redundancies, 3 gastrocolic refluxes, 2 cervical anastomotic stenoses, and 1 each intestinal obstruction due to adhesions, cologastric stricture, cosmetic deformity of the thorax, and bulging of the neck. Six patients with complications required secondary surgery. There were 4 deaths, 2 of them unrelated to the surgery. Cervical leakage, which was the most commonly observed problem, healed well. We believe the colon is still one of the best substitutes for the esophagus and that there is no need to perform a routine pyloroplasty or antireflux procedure as an adjunct to the primary surgery.

[Crohn disease of the esophagus]

INTRODUCTION

Since the landmark report by Crohn, Ginzburg and Oppenheimer in 1932, the spectrum of involvement of Crohn's disease has expanded to include the entire digestive tract from mouth to anus. The involvement of the esophagus by Crohn's disease is very rare.

METHODS

We report a 41-year-old male patient with severe Crohn's disease of the distal esophagus with a fistula to the right bronchial system.

RESULTS

After a long period of nutritional support we performed a transthoracic esophagectomy and a Nissen fundoplication. Postoperatively his course was complicated by pneumonia and withdrawal symptoms.

CONCLUSIONS

Esophagectomy is indicated in Crohn's disease of the esophagus with severe stricture or fistula formations.

Microvascular prefabricated free skin flaps for esophageal reconstruction in difficult patients

BACKGROUND

Reconstruction of the esophagus for complicated benign stricture or after resection of malignant lesion is still a challenge for surgeons. When abdominal viscera cannot be used, skin flaps are selected for esophageal reconstruction. However, skin flaps for esophageal reconstruction are notorious for leakage, and have not been widely accepted. Prefabrication before microvascular transfer to its final site can improve the result of esophageal reconstruction when skin flaps are used.

METHODS

Eight patients with complicated corrosive esophagitis had been treated with prefabricated skin flaps for esophageal reconstruction. The procedures are described in detail.

RESULTS

All patients healed well without leakage. The barium study showed smooth passage. There was no dysphasia or regurgitation after education. Pulmonary complication happened in only 1 patient. Revision for the distal anastomosis was required in 1 patient due to narrowing. When the skin tube is long, the patients need water (or soup) to facilitate swallowing and occasionally use their hand to help the food passage. This method has the following advantages: (1) healing of the long suture line before transfer to withstand the intestinal juice; (2) reliable viability in the distal part of the flap, especially when an extended length of the flap is required; (3) more length of stable tissue for two-layered, tension-free anastomosis at the junction of skin and gastrointestinal mucosa to prevent leakage; and (4) the flap can be placed in the substernal position to meet the aesthetic requirement of young patients. The disadvantage was the staged operations. However, after prefabrication the transfer becomes safe and free of leakage. The overall morbidity is minimal.

CONCLUSIONS

In rare situations when skin flaps are used for esophageal reconstruction, prefabrication provides advantages over conventional one-stage methods, although it needs additional procedures. This method is a combination of conventional technique and microsurgery.

The thoracic surgeon's role in the management of patients with HIV infection and AIDS

The advent of improved medical therapy with multidrug HIV medicines including protease inhibitors has prolonged life expectation of patients with HIV infection. The risk of perinatal transmission has also decreased with education and antiviral medications. Education of all groups about precautions to decrease HIV transmission appears to have resulted in a decline in the disease incidence; however, this trend has not been mirrored in other countries. All of these factors combine to increase the probability that the surgeon's role to take care of patients with HIV-related illnesses could be significant in the future. The thoracic surgeon may be called upon to assist in the diagnosis and treatment of HIV-infected patients with thoracic complications including pulmonary, cardiac, and esophageal problems. The morbidity and mortality of procedures performed on these patients appear to be no different than patients without HIV. We use very aggressive treatment strategies in patients with AIDS and HIV infections. The use of VATS, especially in the treatment of pneumothoraces and empyemas, should be used and has been shown to be safe and efficacious.

Surgical experience improves the long-term results of Nissen fundoplication

BACKGROUND

Nissen fundoplication relieves symptoms of gastro-oesophageal reflux and effectively heals oesophagitis. During long-term follow-up some cases of recurrent reflux are seen. We investigated the possibility that long-term cure of gastro-oesophageal reflux after fundoplication is influenced by the surgeon's experience and focused interest, in line with results of surgery for rectal, gastric, and breast cancer.

METHODS

One hundred and five consecutive patients were evaluated a median of 77 months after open Nissen-Rossetti fundoplication for erosive oesophagitis. Follow-up included personal interviews and upper gastrointestinal endoscopy by an investigator not previously involved in the patients' treatment. The surgeons were classified as experienced (>10 of the operations in the series), less experienced (<10 operations), or trainees.

RESULTS

Of the most experienced surgeons' patients, 97% had no or at most mild reflux symptoms at follow-up, compared with 88% of the of less experienced surgeons' patients (P = 0.04). Healing of erosive oesophagitis was commoner when the operations were performed by experienced specialist surgeons (88% versus 72%; P = 0.04). The reoperation rate fell as the surgeons' experience increased, from 12% to 4%.

CONCLUSIONS

Surgery for gastro-oesophageal reflux should be centralized to units specializing in the techniques and with sufficient annual numbers of operations to optimize results. This policy becomes especially advisable as laparoscopic surgery increases the numbers of treated patients.

Surgical management of necrotizing Candida esophagitis

Invasive esophageal candidiasis produced transmural necrosis leading to perforation in 2 patients aged 10 and 27 years. Both patients survived after esophageal resection and complete diversion. One patient with acute leukemia and neutropenia experienced systemic candidiasis, which resolved after esophagectomy. Esophagectomy and diversion for yeast-induced necrosis may lead to complete recovery and resolution of disseminated candidiasis when combined with systemic antifungal therapy.
