The role of esophagectomy in the management of esophageal perforations

Transgastric drainage of the perforated esophagus: our experiences over 10 years

We first described the technique of transgastric drainage of esophageal injuries in 2008. The method establishes vacuum drainage of the lumen of the esophagus, while maintaining patency, effectively exteriorizing the perforation to allow healing. We summarize this technique and present our experiences from the largest published series of patients. Our unit has treated selected esophageal injuries with transgastric drainage for 10 years. Indications include perforations not amenable to primary repair and treatment failure following prior surgical intervention. A 36 French silastic chest drain is pulled through the abdominal and stomach wall and introduced into the esophagus so that it crosses the perforation. Gastropexy is performed. Mediastinal decontamination and drainage are performed as needed. Continuous suction of -10 cm water is applied. Leak resolution is assessed with weekly water-soluble swallows. For this retrospective observational study, we analyzed data for patients with esophageal perforation, between 2012 and 2022. Inpatient mortality and time to leak resolution were set as primary and secondary outcomes. Esophageal perforations were treated with transgastric drain in 35 patients, of whom 68% (n = 24) were men. Median age was 67 (26-84). Spontaneous perforations accounted for 60% (n = 21), 31% (n = 11) were iatrogenic and 6% (n = 2) were ischemic. Inpatient and 30-day mortality was 14% (n = 5). Among successful treatments, the median length to resolution of leak on imaging was 34.5 days (6-80). Transgastric drainage can successfully treat esophageal perforations, where primary repair is not feasible. The mortality rate of 14% and reduced morbidity compares favorably with other traditional methods of management for esophageal perforation.

Esophageal perforation etiology, outcome, and the role of surgical management - an 18-year experience of surgical cases in a referral center

INTRODUCTION

Esophageal perforation is a surgical emergency with a high rate of morbidity and mortality. Its poor prognosis is mainly associated with previous patient-specific comorbidities and a lack of timely diagnosis and treatment. The objective of this study was to investigate the etiological factors and different surgical methods of treatment with consideration of mortality rate and comorbidities.

METHOD

The present cross-sectional study was conducted on patients who underwent surgical intervention due to esophageal injury from 2002 to 2019 (18 years). Demographic and clinical characteristics along with performed surgical interventions were evaluated accordingly.

RESULTS

In this study, 69 patients with a mean age of 38.8 years were evaluated, of which 45 (65.2%) cases were men. In terms of location of the perforation, the thoracic portion of the esophagus followed by the cervical and abdominal esophagus were more frequently injured with a rate of 32 (46.4%), 30 (43.5%), and 19 (27.5%) cases, respectively. Accordingly, foreign body ingestion followed by penetrating injuries were the most common causative agents leading to esophageal perforation.

CONCLUSION

Obtaining the desired results from the treatment of this condition depends on factors such as patients' previous comorbidities, cause of the rupture, the location of the esophageal damage, and delay in the start of treatment. Since there is no single gold standard treatment strategy, each patient should be individually evaluated.

Unconventional surgery for thoracic esophageal rupture with empyema and mediastinitis: a case report and literature review

Treatment of esophageal perforation or rupture is complicated and controversial, especially in advanced cases. In fact, it is generally accepted that this disease must be treated individually according to the location, causes and clinical features of rupture or perforation. A very rare case was admitted to our department, who was injured 5 days ago by high-pressure gas of a running air compressor and resulted in a long-term longitudinal rupture of the thoracic esophagus. Although the patient suffered from empyema and mediastinitis at the same time, and his condition was very serious, the debridement and desquamation of empyema were still implemented, followed by left thoracic esophagectomy and left neck approach esophagogastrostomy in the same period successfully. The patient got a good result finally.

Acute mediastinitis, mediastinal granuloma, and chronic fibrosing mediastinitis: A review

Acute mediastinitis is a rare infection that carries high morbidity and mortality. They are complications seen most often with deep sternal wound infections from surgeries with median sternotomies, oropharyngeal and odontogenic infections and esophageal perforations. These conditions should be promptly recognized and treated. Mediastinal granulomas are focal, mass-like lesions commonly resulting from prior granulomatous infections. They are regarded as benign, self-resolving lesions however can cause complications by compression of adjacent mediastinal structures. Chronic fibrosing mediastinitis is a rare, diffuse fibroinflammatory process most often seen with granulomatous infections and carries a worse prognosis than mediastinal granulomas especially when adjacent mediastinal structures are compromised. In this review, we discuss the epidemiology, etiology, clinical presentation, treatment and prognosis of acute mediastinitis, mediastinal granulomas, and chronic fibrosing mediastinitis.

Challenges faced in the management of complicated Boerhaave syndrome: a tertiary care center experience

Spontaneous esophageal perforation is rare and is associated with high morbidity and mortality. A spectrum of various surgical modalities ranging from primary surgical repair to esophagectomy is available for its management. The optimal management of patients presenting late in a hemodynamically stable condition is not clearly defined in the literature. A retrospective review of all patients with Boerhaave syndrome managed by a single surgical team in a tertiary care center between 2008 and 2019 was performed (n = 16). Eleven patients were initially managed in the medical intensive care unit (MICU) as non-esophageal cause and 5 patients were referred after failed management (conservative/endoscopic). Demographics, clinical presentation, characteristics of perforation, initial diagnosis, and treatment were analyzed. All patients were males with a mean age of 42.2 years. A history of ethanol use was present in 6 patients. The median delay in diagnosis and referral was 16 days (range: 11-40 days). The common presenting symptoms were chest pain (n=11), dyspnoea (n=10), vomiting (n=4) and cough (n=2). The perforation was directed into right, left, and bilateral pleural cavities in 6, 8, and 2 patients respectively. The location of perforation was distal esophagus except for one patient. One patient was successfully treated with conservative management. The remaining patients underwent esophagectomy as a definitive surgical procedure. There was no significant postoperative morbidity and mortality. Esophagectomy can be done as a one-stage definitive procedure for patients with Boerhaave syndrome who present late in a hemodynamically stable condition with acceptable morbidity and good long term outcome.

Spontaneous Perforation of a Malignified Corrosive Stricture of the Esophagus and Subsequent Perforation of a Giant Duodenal Stress ULCUS

Surgical interventions for corrosive stricture of the esophagus are extremely difficult and technically challenging. In this manuscript, we present a patient with esophagectomy due to perforation of a corrosive stricture of the esophagus that underwent malignant transformation and subsequent perforation of a giant duodenal stress ulcus, which occurred 12 days after the intervention. We performed a total esophagectomy, pharyngo- and gastrostomy, suture of the duodenal perforation but the postoperative period was challenging and despite our efforts, the patient died on the 50th postoperative day due to respiratory and renal failure.

The insidious presentation and challenging management of esophageal perforation following diagnostic and therapeutic interventions

Diagnostic and therapeutic interventions on the esophagus or adjacent organs are responsible for nearly half of all esophageal perforations. If not recognized at the time of the injury, iatrogenic esophageal perforations can present insidiously and lead to delay in diagnosis, thereby increasing morbidity and mortality. Acute clinical awareness is vital for prompt diagnosis, which is usually confirmed with contrast esophagography and contrast-enhanced computed tomography. After establishment of diagnosis, treatment should be promptly initiated and include fluid-volume resuscitation, cessation of oral intake, nasogastric tube insertion, broad-spectrum antibiotics and analgesia. Primary repair, when feasible, is the treatment of choice. Additional procedures beyond primary repair, such as relief of concomitant obstruction, may be necessary if there is underlying esophageal pathology. Drainage alone can be performed for perforations of the cervical esophagus that cannot be visualized. Esophageal T-tube placement or exclusion and diversion techniques are appropriate in clinically unstable patients and in cases where primary repair is precluded either due to preexisting esophageal disease or extensive esophageal damage. Esophagectomy should be performed in patients with malignancy, end-stage benign esophageal disease or extensive esophageal damage that precludes repair. Endoscopic techniques, including stenting, clipping or vacuum therapy, can be used in select cases. Finally, nonoperative management should be reserved for patients with contained esophageal perforations, limited extraluminal soilage and no evidence of systemic inflammation.

The decrease of BMI and albumin levels influences the rate of anastomotic leaks in patients following reconstruction after emergency diverting esophagectomy

OBJECTIVES

Diverting esophagectomies in cases of benign esophageal perforations remain rare but potentially life saving procedures. Usually, an esophagostoma and a feeding jejunostomy or gastrostomy are created, and patients are given time to recover from the emergency situation. However, little is known about morbidity and mortality as well as the optimal timing for a staged reconstruction.

METHODS

Patients with benign esophageal perforations were selected from our retrospective database. Perforations in esophageal malignancies were excluded to avoid bias on patients' general outcome. Clinical parameters and especially, the influence of the nutritional status indicated by the BMI (Body Mass Index) as well as serum albumin levels (g/l) were analyzed.

RESULTS

A total of 24 patients with diverting esophagectomies were identified. Of these, 13 (54.2%) patients received a staged reconstruction after a median of 143.0 days. Patients presenting for their staged reconstruction demonstrated a significantly decreased level of their BMI (p = 0.026) as compared to their prior hospitalization. Interestingly, the relative decrease of BMI (8.5 kg/m² vs. 4.3 kg/m²) and albumin levels (6.5 g/l vs. 0.0 g/l) was significantly different in patients with or without anastomotic leaks between both surgeries (p = 0.021; p = 0.034, respectively). In addition, higher rates of overall complications were associated with an increased rate of malnutrition.

CONCLUSIONS

The relative amount of malnutrition indicated by BMI or serum albumin levels influences the rate of anastomotic leaks and general complications in patients with staged reconstruction after diverting esophagectomy for non-malignant esophageal perforations. Hence, reconstruction should be done as fast as possible to reduce the amount of malnutrition and a frequent assessment of the nutritional status must be done during recovery from the emergency surgery.

Emergent Minimally Invasive Esophagogastrectomy

Introduction. Esophageal perforation in the setting of a malignancy carries a high morbidity and mortality. We describe our management of such a patient using minimally invasive approach. Methods. An 83-year-old female presented with an iatrogenic esophageal perforation during the workup of dysphagia. She was referred for surgical evaluation immediately after the event which occurred in the endoscopy suite. Minimally invasive esophagectomy was chosen to provide definitive treatment for both her malignancy and esophageal perforation. Results. Following an uncomplicated operative course, she was eventually discharged to extended care for rehabilitation and remains alive four years after her resection. Conclusion. Although traditional open techniques are the accepted gold standard of treatment for esophageal perforation, minimally invasive esophagectomy plays an important role in experienced hands and may be offered to such patients.

Open surgery versus stent placement in failed primary surgical treatment of esophageal perforation - a single institutional experience

BACKGROUND

Surgical treatment is an accepted method to manage esophageal perforation, but in many cases it may result in failure. This paper compares the efficacy of surgical treatment and stenting in patients after previous surgical intervention for esophageal perforation.

METHODS

A single-institution retrospective study was performed in a group of patients treated for esophageal perforation admitted to our centre from 2010 to 2015. Seventy eight patients (76.5%) with esophageal perforation received surgical treatment. In this group of patients, the mean time between perforation and treatment was 80.6 h (24-240 h). Spontaneous and iatrogenic perforation was observed in 33 (42.3%) and 45 (57.7%) patients, respectively. Partial esophageal resection was performed in 11 cases (14.1%). The perforation site was sutured in the remaining 67 patients (85.9%). Surgical treatment failed in 29 cases (37.2%).

RESULTS

In patients with failed previous surgical treatment, revision surgery was performed in 14 patients (48.3%) (group A), and a large-diameter self-expandable stent was implanted in 15 cases (51.7%) (group B). Perforation in the thoracic and distal esophagus was observed in 5 (35.7%) and 9 (64.3%) patients from group A, and in 7 (46.7%) and 8 (53.3%) patients from group B, respectively. The mean intubation time in both groups was 30.3 and 12.5 days (p < 0.001), respectively. The mean daily drainage within five days after the intervention was 350 mL in group A, and 500 mL in group B (p < 0.02). In both groups hospitalisation time was 41.5 and 19.4 days, respectively (p < 0.001). Six patients died (42.8%) following revision surgery, and 2 (13.3%) patients died after stent implantation (p < 0.001).

CONCLUSIONS

Intubation time, hospitalization, and the rate of fatal complications in patients who underwent stent implantations were significantly lower compared to reoperated patients; however, the rate of prolonged drainage was lower in patients who underwent revision surgery. In conclusion, stent implantation is a significantly superior method to treat persistent leakage following failure of previous surgical treatment.

T-tube placement as a method for treating penetrating oesophageal injuries

•

The use of T tube for blunt and iatrogenic injuries has been well described however its use in penetrating trauma setting has rarely been reported.

•

T tube drainage can be used in penetrating trauma setting in both acute and delayed presentations as an effective treatment option for oesophageal defects.

•

In settings where primary repair cannot be under taken due to extensive inflammation and in hemodynamically unstable patients T tube provides a safe and invaluable treatment option.

•

T tube acts as a controlled fistula allowing drainage reducing contamination and preventing fulminant mediastinitis.

Introduction

Penetrating oesophageal injuries are extremely rare. Their timely recognition can be difficult and optimal treatment remains controversial. Early recognition of injury is possible with the help of a high index of suspicion and early radiological and endoscopic examinations. Prompt surgical intervention with primary repair of injury, should be the goal.

Presentation of cases

We describe two cases of penetrating oesophageal trauma where T-Tube placement through the oesophageal defect, was successfully employed. Both cases proved to be challenging due to time lapse after injury and anatomical location.

Discussion

Penetrating injuries to the Oesophagus are rare with a reported incidence of 11–17%, most are due to gunshot injuries or stabbings, cervical followed by the thoracic Oesophagus are most at risk. In delayed presentations and sepsis related multi-organ instability, diversion and drainage are considered appropriate. T-tube placement through defects in difficult situations of delayed presentation is well described in setting of iatrogenic perforations. Their use has been described in penetrating injuries but much less frequently.

Conclusion

T-tube placement though oesophageal defects can prove to be an effective treatment option to repair both iatrogenic and penetrating injuries of the Oesophagus, whether early or delayed.

Delayed Esophagus Perforation after Anterior Cervical Spine Surgery

Esophageal perforation is a serious possible complication after anterior cervical discectomy and fusion (ACDF). It usually occurs during the first postoperative day. Esophageal perforation is a potentially life-threatening complication. A 63-year-old man who underwent ACDF 8 years prior visited our emergency room with recurrent aspiration pneumonia, fever, dysphagia and neck pain. Endoscopic study showed esophageal perforation by cervical plate. Successful treatment of the perforation resulted after surgical repair using a sternocleidomastoid muscle flap. We presented a rare case of delayed esophageal perforation after ACDF and successful treatment of the perforation by surgical repair using a sternocleidomastoid muscle flap.

Evaluation of urgent esophagectomy in esophageal perforation

Background

Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice.

Aim

To demonstrate and to analyze the results of urgent esophagectomy in a series of patients with esophageal perforation.

Methods

A retrospective study of 31 patients with confirmed esophageal perforation. Most injuries were due to endoscopic dilatation of benign esophageal disorders, which had evolved with stenosis. The diagnosis of perforation was based on clinical parameters, laboratory tests, and endoscopic images. ‪The main surgical technique used was transmediastinal esophagectomy followed by reconstruction of the digestive tract in a second surgical procedure. Patients were evaluated for the development of systemic and local complications, especially for the dehiscence or stricture of the anastomosis of the cervical esophagus with either the stomach or the transposed colon.

Results

Early postoperative evaluation showed a survival rate of 77.1% in relation to the proposed surgery, and 45% of these patients presented no further complications. The other patients had one or more complications, being pulmonary infection and anastomotic fistula the most frequent. The seven patients (22.9%) who underwent esophageal resection 48 hours after the diagnosis died of sepsis. At medium and long-term assessments, most patients reported a good quality of life and full satisfaction regarding the surgery outcomes.

Conclusions

Despite the morbidity, emergency esophagectomy has its validity, especially in well indicated cases of esophageal perforation subsequent to endoscopic dilation for benign strictures.

Successful primary staple-repair of thoracic oesophagus after delayed presentation of a spontaneous perforation

INTRODUCTION

Spontaneous perforation of the oesophagus is diagnosed late in over 50% of cases. Misdiagnosis may be due to atypical presentations. Primary repair is technically demanding in this setting and the risk of failure is high.

PRESENTATION OF CASE

An 85 year-old lady presented with an atypical cohort of mild nonspecific symptoms in spite of a pleuro-mediastinal purulent collection secondary to an undiagnosed spontaneous perforation of the oesophagus occurred seven days before. Despite the extent of perforation (3cm in length), the late diagnosis and the necrosis of the muscular wall, the oesophagus was successfully repaired by means of a stapler.

DISCUSSION

The mechanism of the atypical presentation is discussed and possible modalities of treatment of delayed oesophageal perforations are reviewed, with particular reference to primary repair and to the possible use of staplers within this setting.

CONCLUSION

Even large spontaneous perforations of the oesophagus can result in a contained abscess, with no frank sepsis. Diagnosis can be missed for days in these cases. The attempt at primary repair of the oesophagus is still indicated. The use of a stapler is preferable in such cases as a perfect mucosal approximation is provided with minimal manipulation and with the use of inert, well tolerated material, which does not tend to become infected.

Repair of complete longitudinal esophageal rupture with preservation of esophageal motility

There is no consensus on the ideal treatment for esophageal perforation and on the maximal extent of esophageal disruption amenable to primary repair. The effect of extensive esophageal injury on postoperative esophageal motility is also unknown. We report the case of a longitudinal iatrogenic esophageal laceration extending from the hypopharynx to the cardia in a morbidly obese patient treated with primary repair. The patient exhibited no postoperative esophageal leak or stricture and maintained a preserved esophageal peristalsis on manometry at 3 months. An extensively lacerated esophagus can be repaired primarily while maintaining a normal postoperative function.

Efficacy of surgical versus conservative treatment in esophageal perforation: a systematic review of case series studies

PURPOSE

To evaluate the efficacy of surgical treatment for esophageal perforation.

METHODS

A systematic review of the literature was performed. We conducted a search strategy in the main electronic databases such as PubMed, Embase and Lilacs to identify all case series.

RESULTS

Thirty three case series met the inclusion criteria with a total of 1417 participants. The predominant etiology was iatrogenic (54.2%) followed by spontaneous cause (20.4%) and in 66.1% the localization was thoracic. In 65.4% and 33.4% surgical and conservative therapy, respectively, was considered the first choice. There was a statistically significance different with regards mortality rate favoring the surgical group (16.3%) versus conservative treatment (21.2%) (p<0.05).

CONCLUSION

Surgical treatment was more effective and safe than conservative treatment concerning mortality rates, although the possibility of bias due to clinical and methodological heterogeneity among the included studies and the level of evidence that cannot be ruled out.

Evaluation of prognostic value of selected biochemical markers in surgically treated patients with acute mediastinitis

BACKGROUND

Monitoring of biochemical markers of inflammation in acute mediastinitis (AM) can be useful in the modification of treatment. This study was a retrospective evaluation of selected biochemical parameters with negative impact on the prognosis in surgically treated patients.

MATERIAL/METHODS

There were 44 consecutive patients treated surgically due to AM of differentiated etiology. Selected biochemical markers (WBC, RBC, HGB, HCT, PLT, CRP, PCT, ionogram, protein and albumins) were assessed before surgery and on the 3rd day after surgery. ANOVA was applied to find factors influencing observations. Numerical data [laboratory parameters] were compared by means of medians.

RESULTS

The overall hospital mortality rate was 31.82%. In the group of dead patients, there were observed statistically significant lower mean preoperative values of RBC [p=0.0090], HGB [p=0.0286], HCT [p=0.0354], protein [p= 0.0037], albumins [p=0.0003] and sodium [p<0.0001] and elevated values of CRP [P=0.0107] and PCT p<0.0001]. High level of inflammatory markers on day 3 after surgery was found to increase the risk of death - for WBC (by 67%), for CRP (by 88%) and for PCT (by 100%).

CONCLUSIONS

Poor prognosis was more frequent in patients with preoperative high levels of CRP, PCT, anemia, hypoproteinemia and hyponatremia. The risk of death increases significantly if in the immediate postoperative period no distinct decrease in WBC count and of the CRP and PCT level is observed. In such a situation the patients should be qualified earlier for broadened diagnostic workup and for reoperation.

Is oesophagectomy or conservative treatment for delayed benign oesophageal perforation the better option?

A best evidence topic was written according to a structured protocol. The question addressed was, 'Is oesophagectomy or conservative treatment for delayed benign oesophageal perforation the better option?' Seven papers were identified that provided the best evidence to answer the question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these studies were tabulated. A total of 147 patients from the studies had oesophageal perforation, while 86 had oesophagectomies for delayed oesophageal perforation (DOP; defined as a perforation diagnosed after 24 h) and 57 had conservative procedures. The mortality rate ranged from 0 to 18% for patients with oesophagectomies, increasing to 50% with double exclusion and reaching as high as 68% in primary repair. In one report, it was found that conservative procedures inflicted higher morbidity than oesophagectomy, which eliminated the perforation, the source of sepsis and the underlying oesophageal disease; another study came to the same conclusion. One study concurred that oesophageal perforation was a surgical disease and only a few cases qualified for conservative procedures. In a review of 34 patients who had DOP, 19 were treated with conservative procedures and 15 oesophagectomy; the mortality rate for patients treated by conservative procedures was 68%, whereas it was 13.3% for patients treated by oesophagectomy. In another study, among the patients treated with conservative procedures, at least one required an additional operation and about 33.3% of patients who survived had continued difficulty with swallowing. In four of the studies, the authors observed that oesophagectomy for DOP was a better surgical option, which decreased mortality, and one study compared the treatment outcome between conservative procedures and oesophagectomy. The primary end-point in all the studies was elimination of the source of sepsis by extirpating the perforated oesophagus in comparison with conservative procedures. However, the consensus of opinion in all the presented evidence was in support of the theory that oesophagectomy was safer and better than conservative procedures. In conclusion, oesophagectomy for DOP was superior to conservative procedures. The limitation of the present review was the lack of many randomized controlled trials.

Treatment of early and delayed esophageal perforation

Esophageal perforations are life threatening emergencies associated with high morbidity and mortality. We report on 22 consecutive patients (age 20-86; 13 female and 9 male) with an oesophageal perforation treated at the university hospital Duesseldorf. The patients' charts were reviewed and follow-up was completed for all patients until demission, healed reconstruction or death. Patients' history, clinical presentation, time interval to surgical presentation, and treatment modality were recorded and correlated with patients' outcome. Six esophageal perforations were due to a Boerhaave-syndrome, eleven caused by endoscopic perforation, two after osteosynthesis of the cervical spine and three foreign body induced. In 7 patients a primary local suture was performed, in 4 cases a supplemental muscle flap was interposed, and 7 patients underwent an oesophageal resection. Four patients were treated without surgery (three esophageal stent implantations, one conservative treatment). Eleven patients (50 %) were presented within 24 h of perforation, and 11 patients (50 %) afterwards. Time delay correlates with survival. In 17 (80.9 %) cases a surgical sufficient reconstruction could be achieved. One (4.7 %) patient is waiting for reconstruction after esophagectomy. Four (18.2 %) patients died. A small subset of patients can be treated conservatively by stenting of the Esophagus, if the patient presents early. In the majority of patients a primary repair (muscle flap etc.) can be performed with good prognosis. If the patient presents delayed with extensive necrosis or mediastinitis, oesophagectomy and secondary repair is the only treatment option with high mortality.

A successful strategy for surgical treatment of Boerhaave's syndrome

BACKGROUND

This retrospective single-institution study presents a successful treatment strategy for Boerhaave's syndrome.

METHODS

During 1995-2008, 15 patients with spontaneous esophageal perforation were treated. Patients were grouped according to time from symptoms to referral (early, <24 h; late, >24 h). In group I (early, n = 8 patients) treatment comprised primary surgical esophageal repair in seven cases and endoscopic clipping in one case. In group II (late, n = 7 patients) treatment comprised esophagectomy without primary reconstruction (4 cases) or controlled esophagocutaneous fistula (3 cases). Measures of outcome included age (years), delay to diagnosis (h), severe sepsis on admission, mortality, and hospital and intensive care unit (ICU) stay.

RESULTS

The overall hospital mortality rate was 6.6% (1/15), being 0% (0/8) in group I and 14.2% (1/7) in group II. Patient age (49.6 vs. 68.6 years, P < 0.0001), delay to diagnosis (17.75 vs. 69 h, P < 0.0001), severe sepsis on admission (0 vs. 4, P = 0.0256), and ICU stay (4 vs. 14 days, P = 0.006) were all greater in group II.

CONCLUSIONS

Early diagnosis and carefully selected therapeutic tactics can reduce the mortality rate of Boerhaave's syndrome to an acceptably low level. Methods of organ preservation and minimally invasive techniques can be applied successfully in the treatment.

Successful treatment of a spontaneous esophageal rupture in an elderly patient: a case report

An 80-year-old woman was admitted to our hospital with severe chest and back pains after vomiting. Computed tomography (CT) of the chest revealed left-sided pneumothorax and pleural effusion. Some food was drained from an inserted chest tube, and we diagnosed spontaneous esophageal rupture (Boerhaave's syndrome). A left thoracotomy was performed 7 hours after the onset of symptoms. A 3-cm perforation was discovered in the lateral wall of the distal esophagus. The perforation was repaired with a primary two-layered closure and covered with pericardial fat. The patient had a good postoperative course and was discharged 1 month after surgery. This case suggests the importance of early surgical treatment, even in elderly patients with spontaneous esophageal rupture.

Management of Esophageal Perforation in Adults

Perforation of esophagus in the adult is a very morbid condition with high morbidity and mortality. The ideal treatment is controversial. The main causes for esophageal perforation in adults are iatrogenic, traumatic, spontaneous and foreign bodies. The morbidity and mortality rate is directly related to the delay in diagnosis and initiation of optimum treatment. The reported mortality from treated esophageal perforation is 10% to 25%, when therapy is initiated within 24 hours of perforation, but it could rise up to 40% to 60% when the treatment is delayed beyond 48 hours. Primary closure of the perforation site and wide drainage of the mediastinum is recommended if perforation is detected in less than 24 hours. Treatment option for delayed or missed rupture of esophagus is not very clear and is controversial. Recently a substantial number of patients with esophageal perforation are being managed by nonoperative measures. Patients with small perforations and minimal extraesophageal involvement may be better managed by nonoperative treatment Major prognostic factors determining mortality are the etiology and site of the injury, the presence of underlying esophageal pathology, the delay in diagnosis and the method of treatment. For optimum outcome for management of esophageal perforations in adults a multidisciplinary approach is needed.

Esophageal perforation in South of Sweden: results of surgical treatment in 125 consecutive patients

BACKGROUND

For many years there has been a debate as to which is the method of choice in treating patients with esophageal perforation. The literature consists mainly of small case series. Strategies for aiding patients struck with this disease is changing as new and less traumatic treatment options are developing. We studied a relatively large consecutive material of esophageal perforations in an effort to evaluate prognostic factors, diagnostic efforts and treatment strategy in these patients.

METHODS

125 consecutive patients treated at the University Hospital of Lund from 1970 to 2006 were studied retrospectively. Prognostic factors were evaluated using the Cox proportional hazards model.

RESULTS

Pre-operative ASA score was the only factor that significantly influenced outcome. Neck incision for cervical perforation (n = 8) and treatment with a covered stent with or without open drainage for a thoracic perforation (n = 6) had the lowest mortality. Esophageal resection (n = 8) had the highest mortality. A CAT scan or an oesophageal X-ray with oral contrast were the most efficient diagnostic tools. The preferred treatment strategy changed over the course of the study period, from a more aggressive surgical approach towards using covered stents to seal the perforation.

CONCLUSION

Pre-operative ASA score was the only factor that significantly influenced outcome in this study. Treatment strategies are changing as less traumatic options have become available. Sealing an esophageal perforation with a covered stent, in combination with open or closed drainage when necessary, is a promising treatment strategy.

Esophagectomy for a traumatic esophageal perforation with delayed diagnosis

Esophageal perforations are rare, and traumatic perforations are even more infrequent. Due to the rarity of this condition and its nonspecific presentation, the diagnosis and treatment of this type of perforation are delayed in more than 50% of patients, which leads to a high mortality rate. An 18-year-old male patient was brought to the emergency room with a penetrating neck injury, caused by a gunshot wound. He was taken to the operating room and underwent surgical exploration of the neck and a chest tube was inserted to treat the hemo- and pneumothorax. During the procedure, a 2 cm lesion was detected in the esophagus, and the patient underwent a primary repair. A contrast leakage into his right hemithorax was noticed on the 4th postoperative day; he was submitted to new surgery, and a subtotal esophagectomy and jejunostomy were performed. He was discharged from the hospital in good condition 20 d after the last procedure. The discussion around this topic focuses on the importance of the timing of diagnosis and the subsequent treatment. In early diagnosed patients, more conservative therapeutics should be performed, such as primary repair, while in those with delayed diagnosis, the patient should be submitted to more aggressive and definitive treatment.

Delayed presentation of intrathoracic esophageal perforation after pneumatic dilation for achalasia

Pneumatic dilation (PD) is considered to be a safe and effective first line therapy for achalasia. The major adverse event caused by PD is esophageal perforation but an immediate gastrografin test may not always detect a perforation. It has been reported that delayed management of perforation for more than 24 h is associated with high mortality. Surgery is the treatment of choice within 24 h, but the management of delayed perforation remains controversial. Hereby, we report a delayed presentation of intrathoracic esophageal perforation following PD in a 48-year-old woman who suffered from achalasia. She completely recovered after intensive medical care. A review of the literature is also discussed.

How to treat esophageal perforations when determinants and predictors of mortality are considered

BACKGROUND

Published lethality rates of esophageal perforation (EP) vary depending on patient- and disease-related factors. This study was designed to evaluate how these factors impact death. Furthermore, we calculated the predictive accuracy of the Mortality Prediction Model (MPM II) and the Simplified Acute Physiology Score (SAPS II) for in-hospital death. Conclusions about treatment decisions were drawn based on our data and analysis of recent literature.

METHODS

Every patient who was treated for EP at our department from December 2001 to July 2008 is included in this study. Logistic regression analyses of various risk factors, such as etiology, time interval, size, comorbidities, localization, type of treatment, and preexisting pathologies of the esophagus on death, were performed.

RESULTS

Of the 41 patients diagnosed with EP, nine died (21%). The most important risk factor concerning death was cirrhosis of the liver (0 vs. 89% mortality; odds ratio, 208; P<0.001). Accuracy for lethality risk prediction was calculated with MPM II and SAPS II on admission, and afterward the characteristic increase that occurred was evaluated by using receiver operator characteristic curves. Optimal results were achieved by using a characteristic SAPS II increase (AUC 0.86; P: 0.009) after the patient was admitted to the intensive care unit.

CONCLUSIONS

Our study was the first to demonstrate that a rapid or continuous increase more than 40 of the daily SAPS II clearly indicates that a high risk of death is imminent. This should be used as a reevaluation factor when choosing a treatment strategy.

Thoracoscopic and Laparoscopic Esophagectomy in a Case of Spontaneous Rupture of the Esophagus (Boerhaave's Syndrome)

Spontaneous barogenic rupture of the esophagus is a rare disease with high morbidity and mortality. Many therapeutic options are available. Esophagectomy is indicated when a large rupture is found with huge mediastinal contamination. Here, we describe a minimal invasive esophagectomy procedure for an esophageal barogenic rupture. A thoracoscopic esophagectomy was performed with the patient in a prone position. After a laparoscopic gastric tubulization, a cervical esopagho-gastro anastomosis was performed with a retro-sternal passage of the stomach in order to avoid the heavily contaminated posterior mediastinum. The postoperative outcome was almost uneventful. This minimal-invasive approach allowed direct optimal visualization of the esophageal laceration and a thorough mediastinal cleansing, thereby avoiding any septic complications, which are the major concern in this particular clinical procedure. In our case, the esophagectomywas mandatory because of the large laceration and massive mediastinal contamination. The minimal invasive thoracoscopic and laparoscopic esophagectomy approach is feasible even in an emergency setting. This is the first report of this procedure being used in a high-risk patient with Boerhaave's syndrome.

Sternotomy after retrosternal esophagogastric anastomotic disruption: a case report

Disruption of cervical esophagogastric anastomosis after retrosternal stomach transposition remains a dangerous complication. We report a case of cervical gastric disruption after retrosternal gastric transposition in a 36-year-old man that required sternotomy for reanastomosis. After sternotomy, gastric mobilization was possible, in order to gain sufficient length for a new cervical esophagogastric anastomosis.

Management of delayed intrathoracic esophageal perforation with modified intraluminal esophageal stent

In this article, we reviewed our experience of treatment of the delayed intrathoracic nonmalignant esophageal perforation employing modified intraluminal esophageal stent. Between February 1990 and August 2006, eight patients were included in this study. Five patients experienced sepsis. The interval time between perforation and stent placement ranged from 36 h to 27 days (average, 8.6 days). Esophageal stenting and throracotomy for foreign body removal were performed in four patients. The remaining four patients underwent stent placement and thoracostomy. Nutrition was initiated through gastrostomy after 7 to 10 days after the stenting. The stent was removed after the patients resumed oral intake of food and the esophagogram showed that perforation was closed. There was no death in this group. Signs of sepsis remitted 1 week after stent placement. Complications included stress ulcer, stimulative cough, and pneumonia each. Stent removal ranged 32 to 120 days (average 66.7) after its placement. The stent was kept in place for 4 months to prevent formation of esophageal stricture in one patient with caustic esophageal burns. The follow-up was completed in all the patients. The mean follow-up period was 59 months (range 12-180). One patient with caustic esophageal burn underwent cicatricial esophagectomy and gastric transposition 3 years later due to the esophageal stricture. Barium swallow demonstrated that there was a diverticulum-like outpouching in one patient and slight esophageal stricture at T2 and T3 level in another. One patient developed reflux esophagitis 5 years after stent removal. All the patients finally had a normal intake of food. Modified esophageal stenting is an effective method to manage the delayed intrathoracic esophageal perforation. Prevention of stent migration and its convenient adjustment might be the major advantages of this method.

Current management of esophageal perforation: 20 years experience

Esophageal perforations are surgical emergencies associated with high morbidity and mortality rates. No single strategy has been sufficient to deal with the majority of situations. We aim to postulate a therapeutic algorithm for this complication based on 20 years of experience and also on data from published literature. We performed a retrospective clinical review of 44 patients treated for esophageal perforation at our hospital between January 1989 and May 2008. We reviewed the characteristics of these patients, including age, gender, accompanying diseases, etiology of perforation, diagnosis, location, time interval between perforation and diagnosis, treatment of the perforation, morbidity, hospital mortality, and duration of hospitalization. Perforation occurred in the cervical esophagus in 14 patients (31.8%), thoracic esophagus in 18 patients (40.9%), and abdominal esophagus in 12 patients (27.3%). Management of the esophageal perforation included primary closure in 23 patients (52.3%), resection in 7 patients (15.9%), and nonsurgical therapy in 14 patients (31.8%). In the surgically treated group, the mortality rate was 3 of 30 patients (10%), and 2 of 14 patients (14.3%) in the conservatively managed group. Four of the 14 nonsurgical patients were inserted with covered self-expandable stents. The specific treatment of an esophageal perforation should be selected according to each individual patient. To date, the most effective treatment would appear to be operative management. With improvements in endoscopic procedures, the morbidity and mortality rates of esophageal perforations are significantly decreased. We suggest that minimally invasive techniques for the repair of esophageal perforations will be very important in the future treatment of this condition.

[Modern esophageal surgery and late functional results as equations with several unknowns--Hungarian Academy of Sciences Doctoral Thesis]

Using the same surgical method and anatomically ideal primary healing, the functional results could even be different later. Trying to identify various factors being responsible for the above differences, 637 patient's data, who underwent previous oesophago-gastric surgery between 1985-2005, were analyzed. Biochemical, histological and electrophysiological examinations had been evaluated. Developing hypertrophy-like metabolic changes and enteric ganglionitis as morphological alternations of LES muscles induced by GERD may be reasons for complaints after antireflux surgery. The marking of Z-line with endoscopic clips followed by an immediately upright contrast study and substractional evaluation is appropriate for detecting true short esophagus. Open surgical procedures are justified even in the new millennium in cases when the patient already underwent previous upper abdominal operations - due to an increased risk of injury because of adhesions - in cases of primarily recurrent paraesophageal hernias after an unsuccessful open and/or laparoscopic reconstruction, as well as in cases of reflux with complications. When adenocarcinomas of the gastro-oesophageal junction are examined preoperatively, the ratio of the performed catabolic - AMAN, CB, and DPP I - enzymatic activity of the tissue sample from the tumour and adjacent intact mucosa within 2 cm of the tumour may have a prognostic value even in the preoperative examination period, and neo-adjuvant treatment should be considered in these group of patients. The patients' post-operative complaints and symptoms change during the post-operative period and correlate with the parameters of the myoelectric and contractile activities of the "Akiyama stomach". Tachygastria seems to be the major pathogenetic factor involved in the contractile dysfunction. Gastro-jejuno-duodenal interposition represents an adequate 'second-best' method of choice if technical difficulties emerge with jejunal or colon interposition following limited resection of the oesophagus performed due to early Barrett's carcinoma or non-dilatable peptic stricture.

Spontaneous rupture of the oesophagus

BACKGROUND

The aim of this study was to evaluate the diagnosis, management and outcome of patients with spontaneous rupture of the oesophagus in a single centre.

METHODS

Between October 1993 and May 2007, 51 consecutive patients with spontaneous oesophageal rupture were evaluated with contrast radiology and flexible endoscopy. Patients with limited contamination who fulfilled specific criteria were managed by a non-operative approach, whereas the remainder underwent thoracotomy.

RESULTS

The median time to diagnosis was 24 (range 4-604) h. Initial diagnosis was by contrast swallow in 18 of 24 patients, computed tomography in 15 of 17 and endoscopy in 18 of 18. There were no deaths among 17 patients who were managed non-operatively with targeted drainage, intravenous antimicrobials, nasogastric decompression and enteral nutrition. Of 31 patients who underwent primary thoracotomy and oesophageal repair (over a Ttube in 29), 11 died in hospital. Three patients could not be resuscitated adequately and did not have surgical intervention.

CONCLUSION

Spontaneous oesophageal rupture represents a spectrum of disease. Accurate radiological and endoscopic evaluation can identify those suitable for radical non-operative treatment and those who require thoracotomy.

An Eastern perspective on oesophageal perforation: a high incidence of ingested bones

BACKGROUND

Oesophageal perforation is uncommon, with controversy surrounding its optimal management. Our local experience shows a high incidence of oesophageal perforation secondary to ingested bones.

METHODS

Fourteen patients with oesophageal perforation treated at Changi General Hospital in Singapore between January 1996 and December 2006 were retrospectively reviewed.

RESULTS

The median age was 52 years (16-79 years), with eight men and six women. There were 11 thoracic perforations and 3 cervical perforations. Ten perforations were the result of foreign body ingestion, three were spontaneous and only one was iatrogenic. The offending foreign body was a fish bone in five patients, a chicken bone in four and a tooth in one. Three of our 14 patients were treated surgically. The remaining 11 patients were treated non-operatively. All nine patients with fish or chicken bone perforation were treated conservatively, except two in whom conservative therapy failed and they subsequently required surgery. The median length of hospital stay was 7 days (2-109 days). There was one death.

CONCLUSION

Oesophageal perforation requires prompt diagnosis and treatment. Most of our oesophageal perforations are secondary to ingested bones. Such cases can often be treated conservatively in our experience.

Surgical treatment of oesophageal perforation

Several options–but choose wisely

Risk factors for surgical site infection after surgery for esophageal perforation

Esophageal perforations carry a high potential for morbidity and mortality. The prognosis depends on rapid and precise diagnosis and management. Surgical site infections (SSIs) are very common following the surgical treatment of esophageal lesions. We aimed identify significant risk factors for SSI after surgery for esophageal perforation via an historical cohort study including patients who underwent surgical management of esophageal perforation. The predictive variables were analyzed by bivariate analysis and multiple logistic regression. Eighty-one patients were studied during a 10-year period ending in 2004. The mean age was 42.6 years. In 44% of the patients the time interval between the perforation and surgery was up to 6 h and in 30% it was > 24 h. Associated lesions occurred in other cavities; 17% in the chest, 5% in the abdomen, 5% in the extremities, 4% in the spinal column and bone marrow and 2% in the face. There were grade I lesions in eight cases (10%), grade II in 64 cases (79%) and grade III in nine cases (11%). The mean time of surgery procedure was 117.2 min. The mean SSI was 7.99. SSIs occurred in 33 patients (41%). The risk factors for SSI following surgical management of esophageal perforation were: age > or = 50 years, time delay to treatment > 24 h, associated lesion in another cavity and Injury Severity Score > or = 15.

Treatment of large, oesophageal perforations and mediastinitis with a covered, removable metallic endoprosthesis and mediastinal drainage

A bevont fémstentek benignus nyelőcső-stenosisban és -perforatioban való alkalmazása, a stent okozta szöveti reakció és a stent eltávolítás nehézségei miatt, kezdeti stádiumban van. A szerzők nyelőcső-perforatioban egy újabb, bevont fémstent terápiás hatását és eltávolítására kidolgozott módszerük hatékonyságát vizsgálták 3 beteg kapcsán. Három beteg közül kettőnél corrosiv nyelőcsőstenosis tágításakor perforatio lépett fel. Emiatt az egyiknél mediastinalis drenázs és jejunostomia, másiknál primér sutura és drenázs történt. Ezt követően mindkettőben septicus állapot, mediastinitis alakult ki. Ennek hátterében egyiknél perforatio mellett mediastinalis drén okozta nyelőcsőfistula, a másiknál nyelőcsővarrat-elégtelenség állt. A nyelőcső falának defektusát 8, illetve 10 nappal a perforatio, műtét után bevont fémstenttel hidalták át. A harmadik beteg inoperabilis nyelőcsőtumora okozta stenosisának tágítása, stentelési kísérlete során nyelőcsőruptura lépett fel, melyet két órán belül bevont fémstenttel zárta. Parenteralis táplálást, széles spectrumú antibioticus kezelést alkalmaztak. Három nap múlva ellenőrizve mindhárom stent tölcsére tökéletesen zárt. Nasogastricus szonda-, majd per os táplálásra tértek át. Átmeneti mediastinalis drenázs után a stenteket 35, illetve 74 nappal a stentimplantatio után endoscoposan távolították el. Ez idő alatt a nyelőcsőfal-defectusok, a perforatios nyílások záródtak. A stent felső szélénél jelentkező stenosist mindkét betegnél tágították. A 3. betegnél a tumoros nyelőcsőruptura korai, végleges stentelése után szövődmény nem lépett fel. Itt drenázsra nem volt szükség. Nagy nyelőcső-perforatio – kísérő septicus állapot, mediastinitis esetén is – sikeresen gyógyítható bevont, eltávolítható fémstenttel és megfelelő mediastinalis drenázzsal.

Endoscopic management of gastrointestinal leaks

Endoscopic closure of gastrointestinal perforations, fistulas, and anastomotic dehiscence is technically feasible. Endoluminal closure of the instrumental perforations of the gastrointestinal tract can be accomplished immediately after the recognition of perforation, while avoiding the delay of arranging surgery and the trauma associated with thoracotomy or laparotomy. In addition, endoscopic closure should be considered in patients with anastomotic dehiscence and chronic fistulas as this may avoid the risk associated with reoperation. The outcome of closure depends on the technical expertise in the proper selection and use of various endoluminal closure options. Training of the endoscopists in the use of this novel technology will enhance the quality of care of our patients.

Esophageal stent placement for the treatment of iatrogenic intrathoracic esophageal perforation

BACKGROUND

Iatrogenic esophageal perforation after endoscopy or surgery can be a devastating event. Traditional therapy has most often consisted of operative repair of the esophagus. This investigation summarizes our experiences treating iatrogenic intrathoracic perforations of the esophagus using an occlusive removable esophageal stent.

METHODS

Over a 24-month period, patients found to have an iatrogenic intrathoracic esophageal perforation at a tertiary care medical center were offered endoluminal esophageal stent placement instead of operative repair of the esophagus as initial therapy. Excluded were patients with an esophageal malignancy or a chronic esophageal fistula. Silicone-coated stents were placed endoscopically utilizing general anesthesia and fluoroscopy. Adequate drainage of infected areas was also simultaneously achieved. Leak occlusion was confirmed by esophagram. Patients were followed until their stent was removed and their esophageal leak had resolved.

RESULTS

Seventeen patients had 18 esophageal stents placed for acute perforations of the esophagus after endoscopy (8) or surgery (9) during the study period. Associated endoscopic (13) or surgical procedures (7) were performed simultaneously in all 17 patients. Leak occlusion occurred in 16 patients (94%) as confirmed by esophagram. Fourteen patients (82%) were able to initiate oral nutrition within 72 hours of stent placement. One patient (6%) experienced a continued leak after stent placement and underwent operative repair. Stent migration requiring repositioning (2) or replacement (2) occurred in 3 patients (18%). All stents were removed at a mean of 52 +/- 20 days after placement. Hospital length of stay for patients treated with esophageal stent placement was 8 +/- 9 days (median, 5).

CONCLUSIONS

Endoluminal esophageal stent placement is an effective method for the treatment of acute, iatrogenic perforations of the intrathoracic esophagus. These stents result in rapid leak occlusion, provide the opportunity for early oral nutrition, may significantly reduce hospital length of stay, are removable, and avoid the potential morbidity of operative repair.

Transabdominal Approach for Management of Boerhaave's Syndrome

Several transthoracic approaches have been described for the surgical management of Boerhaave's syndrome that carry their own morbidity in patients who can be systemically unwell at presentation, and best practice is not established. We introduce a novel transabdominal approach to manage the perforation and spare these patients the trauma of a thoracotomy. Four patients with spontaneous esophageal rupture were managed using a transabdominal approach. Postoperative complications, length of intensive care unit stay, postoperative hospital stay, time to oral intake, and morbidity and mortality were used as outcome measures. After operation, the median intensive care unit stay was 4 days (range, 0–5) in patients who required a median of 10.5 days (range, 6–17) to establish oral intake. One patient required a transthoracic drainage of an empyema and one patient required percutaneous drainage of a mediastinal collection. The median length of stay was 38 days and there was zero mortality. The transabdominal approach is safe and effective for the management of Boerhaave's syndrome and should be considered in the treatment paradigm for this condition. Intrathoracic complications account for postoperative morbidity.

Boerhaave's syndrome: Diagnosis and surgical management

Spontaneous oesophageal perforation, or Boerhaave's syndrome, represents barogenic oesophageal injury. Patients don't always present with classical features and treatment may be delayed. Various approaches and strategies have been described but, despite advances in surgery and critical care, the condition continues to carry a high morbidity and mortality. Primary repair may be undertaken in patients who present within 24 hours of perforation and remains the gold standard. Increasingly, this strategy is being adopted for patients who present later with similar mortality rates. Diversion with exclusion and resectional procedures may be undertaken when repair is not possible.
