Conservative surgical management of Boerhaave's syndrome: experience of two tertiary referral centers

Outcome of treatment modalities for spontaneous esophageal rupture: a meta-analysis and case series

BACKGROUND

Current treatment modalities for spontaneous esophageal perforation remain controversial because of their rarity.

OBJECTIVE

To describe our institution's experience in managing patients with spontaneous esophageal rupture and conduct a meta-analysis of existing studies to determine the best evidence-based treatment options.

METHODS

The authors enrolled patients with spontaneous esophageal rupture who underwent their first treatment at our institution. The authors also identified studies through a systematic search of the MEDLINE, EMBASE, and Cochrane Library databases before 1 April 2024, for inclusion in the meta-analysis.

RESULTS

This case series included data from 17 patients with delayed diagnosis who were treated with esophageal stents, with an immediate mortality rate of 5.9%. In addition to the cases from our institution, the authors obtained 944 patients from 46 studies in the final analysis. The combined immediate mortality rate was 11% (95% CI: 0.08-0.15). The combined reintervention rate was 11% (95% CI: 0.05-0.19). The combined immediate mortality was 6% (95% CI: 0.04-0.09) after primary closure, 14% (95% CI: 0.02-0.32) after T-tube drain repair, 2% (95% CI: 0.00-0.15) after esophagectomy, 8% (95% CI: 0.03-0.15) after stent placement, and 22% (95% CI: 0.03-0.47) after conservative treatment. The subgroup analysis based on the timing of the intervention showed that the immediate mortality rate in patients initiating treatment within 24 h of rupture was 3% (95% CI: 0.01-0.08), whereas that in patients initiating treatment >24 h later was 12% (95% CI: 0.08-0.18).

CONCLUSION

Outcomes are best after esophagectomy, and primary closure or esophageal stenting is a good option compared with other treatment modalities. Prognosis is related to the timing of intervention, and accurate diagnosis and treatment within 24 h significantly reduces the risk of death in patients. Patients with delayed diagnosis may have a better prognosis with stent placement.

Mediastinal hematoma as an unusual intrathoracic manifestation of Boerhaave Syndrome: A case report

INTRODUCTION

Boerhaave Syndrome (BS) is rare but life-threatening condition caused by a sudden increase in the intraluminal pressure due to vomiting. We present a case of BS manifesting as a posterior mediastinal hematoma, indicative of a potentially fatal condition.

PRESENTATION OF CASE

A 51-year-old man presented with acute chest pain after vomiting. Enhanced Computed Tomography revealed mediastinal fluid with a left pleural effusion, leading to a diagnosis of BS. Emergency surgery revealed a posterior mediastinal hematoma with active bleeding due to a torn proper esophageal artery. Hemostasis and a wall repair were performed, and the patient was discharged uneventfully.

DISCUSSION

This case highlights two important aspects. Firstly, a spontaneous esophageal perforation can manifest as a mediastinal hematoma due to the subpleural arterial injury, delaying bacterial spillage. While preoperative thoracentesis may not always diagnose BS accurately, bloody thoracic drainage can serve as an alternative diagnostic sign. Secondly, the mediastinal hematoma itself poses a serious risk, as it can lead to a catastrophic outcome even before bacterial contamination occurs, emphasizing the necessity of a timely surgical intervention in BS cases.

CONCLUSION

BS can manifest as a mediastinal hematoma, and the absence of gastrointestinal content in the thoracic drainage does not rule out the possibility of BS. Prompt surgical intervention remains essential, as a mediastinal hematoma alone can result in a catastrophic outcome. This case highlights the significance of a comprehensive diagnostic assessment for BS.

Risk factors for the poor prognosis of Benign esophageal perforation: 8-year experience

BACKGROUND

Esophageal perforation (EP) has a high mortality rate and poor prognosis. This single-center retrospective study aims to analyze the related risk factors for benign EP.

METHODS

We retrospectively analyzed 135 patients with benign EP admitted to the First Affiliated Hospital of Nanchang University from January 2012 to December 2020. Univariate and multivariate logistic analysis were performed to estimate risk factors for prognosis of esophageal perforation patients.

RESULTS

There were 118 EP patients with foreign body ingestion and 17 patients with nonforeign body ingestion. Fish bones (78/118) were the most common foreign body and most of the nonforeign EPs were caused by spontaneous esophageal rupture (14/17). Foreign body perforations occurred mostly in the upper thoracic segment (70/118) and middle thoracic segment (31/118), and spontaneous esophageal ruptures occurred mostly in the lower thoracic segment (15/17). Fifteen patients (11.1%) died during hospitalization or within one month of discharge. Multivariable logistic regression analysis showed that high white blood cell (WBC) levels [odds ratio (OR) = 2.229, 95% confidential interval (CI): 0.776-6.403, P = 0.025], chest or mediastinal emphysema (OR = 7.609, 95% CI: 2.418-23.946, P = 0.001), and time to treatment > 72 h (OR = 3.407, 95% CI: 0.674-17.233, P = 0.018) were independent risk factors for poor prognosis.

CONCLUSION

Foreign body was the major reason for benign EP. High WBC level, chest or mediastinal emphysema and time to treatment > 72 h were risk factors for poor prognosis.

Oesophageal rupture after right pneumonectomy: A case report

Oesophageal rupture after pneumonectomy is very rare. Management remains a significant challenge. This current case report describes a patient that underwent right pneumonectomy for right central squamous cell carcinoma. On the third day after the operation, food residues were observed in the thoracic tube. Considering oesophageal rupture, surgery was performed. Intraoperative oesophageal rupture was observed and intermittent suture was performed. Unfortunately, an oesophageal pleural fistula developed. Anti-infection treatment, chest drainage, thoracic irrigation, nutrition support and stent implantation were used after the operation. The patient recovered smoothly and had no discomfort when eating. Oesophageal rupture after pneumonectomy is extremely rare and treatment is very difficult. In our opinion, surgical repair is the key to the treatment of oesophageal rupture. Once an oesophageal pleural fistula occurs, enhanced nutrition, adequate irrigation and drainage and stent implantation are critical factors.

Usefulness of lavage and drainage using video-assisted thoracoscopic surgery for Boerhaave's syndrome: a retrospective analysis

Background

Boerhaave’s syndrome has a high mortality rate due to respiratory failure, septic shock, and multiple organ failure. We had previously carried out primary repair with laparotomy and postoperative computed tomography-guided drainage for mediastinal abscess and empyema. However, this treatment prolonged mechanical ventilator days and length of intensive care unit stay. Therefore, we decided to carry out primary repair with laparotomy and add lavage and drainage using video-assisted thoracoscopic surgery.

Methods

From April 2004 to September 2018, 18 patients with Boerhaave’s syndrome were treated; 6 patients treated conservatively were excluded. Thus, 12 patients who underwent surgical treatment were divided into the computed tomography-guided drainage group (D group) (6 patients) and the lavage and drainage using video-assisted thoracoscopic surgery group (VATS group) (6 patients), and the two groups were retrospectively compared.

Results

The VATS group had significantly longer operation time than the D group {359 [328, 387] vs. 220 [155, 235] min, P=0.004}, but the ventilator-free days (VFDs) were significantly extended {24 [21, 24] vs. 10 [0, 17] days, P=0.02}, and the length of intensive care unit stay was significantly shortened {14 [8, 14] vs. 35 [29, 55] days, P=0.01}.

Conclusions

Lavage and drainage using video-assisted thoracoscopic surgery is an effective surgical method for Boerhaave’s syndrome.

[Surgical treatment of spontaneous esophageal rupture: long-term experience of the Sklifosovsky Research Institute for Emergency Care]

OBJECTIVE

To analyze the treatment outcomes in patients with spontaneous esophageal rupture (SER).

MATERIAL AND METHODS

The study included 106 patients with SER admitted to the Sklifosovsky Research Institute for the period from 1992 to 2015. The sample also included 91 patients who were referred from other hospitals. All patients were divided into 4 groups depending on surgical procedure: surgical drainage (Group I, n=19); suturing the esophageal defect without antireflux surgery (Group II, n=12); esophageal wall repair with fundoplication procedure (Group III, n=62); resection of the thoracic esophagus (Group IV, n=13).

RESULTS

In the 1^st group, complication rate was 100% and significantly exceeded these values in groups II, III, and IV (66.7%, 71%, and 69.2%, respectively; p=0.0318, p=0.0189, and p=0.0413). The length of hospital-stay was the lowest in group IV (mean 42 days) and group I (mean 55 days). Mortality rate in groups I, III and IV was 15-20% lower than in group II. Pneumonia and pleural empyema were significant predictors of poor outcome. Fundoplication improved postoperative outcomes in group III compared to group II. Resection of the thoracic esophagus performed in accordance with strict indications interrupts infectious process and shortens recovery period. Surgical drainage is followed by persistent contamination of mediastinum and pleural cavities that may quickly result a fatal outcome.

CONCLUSION

A differentiated approach to SER treatment can reduce the risk of complications and mortality.

Surgical management of Boerhaave's syndrome with early and delayed diagnosis in adults: a retrospective study of 88 patients

BACKGROUND

spontaneous esophageal rupture (Boerhaave's syndrome) is a rare and challenging clinical condition.

OBJECTIVE

to evaluate the outcome of different surgical treatments for patients with Boerhaave's syndrome with an early diagnosis (< 24 h) and delayed diagnosis (> 24 h), using a retrospective cohort study in a tertiary referral center.

PATIENTS AND METHODS

eighty-eight patients with Boerhaave's syndrome who underwent surgical treatment were identified from March 1994 to March 2019 in the First Hospital of Shanxi Medical University. Subsequently, they were retrospectively divided into two groups according to time from symptom onset to diagnosis (group 1, < 24 h, n = 16; group 2, > 24 h, n = 72). Primary suture repair was used in group 1 and reinforcement with a vascular muscle flap was used in group 2, in order to reduce the incidence of fistula. Patients in group 2 were further divided into two subgroups according to reinforcement using diaphragmatic flaps (subgroup 1) or intercostal muscle flaps (subgroup 2).

RESULTS

the duration of hospitalization and stay in Intensive Care Unit (ICU) was significantly shorter in group 1 (p = 0.027 and p = 0.001). Group 1 had fewer postoperative esophageal leaks (p = 0.037) compared to group 2. Various aspects were compared in the two subgroups and the differences were not statistically significant (p > 0.05).

CONCLUSIONS

it is very important to establish an early diagnosis for patients with Boerhaave's syndrome. Early (< 24 h) and primary suture repair is superior to delayed (> 24 h) primary repair, even for those reinforced with vascular muscle flaps. Furthermore, repair reinforcement with different muscle flaps appears to render similar results for patients with delayed diagnosis.

Successful conservative treatment of spontaneous intrathoracic esophageal perforation using a temporary covered esophageal stent with a check valve: a case report

Background

Spontaneous esophageal perforation is a potentially life-threatening condition with high morbidity and mortality rates. While surgical treatment has been employed for esophageal perforation, we have adopted conservative treatment with an esophageal stent for patients in a poor physical condition because we consider controlling sepsis and improving the physical status are the highest priorities; additionally, the surgical trauma could be fatal for these patients.

Case presentation

A 60-year-old male complaining of left chest and back pain after vomiting was transferred to a local hospital. Computed tomography and chest X-ray examinations showed left tension pneumothorax, pneumomediastinum, and bilateral pleural effusion suspicious of spontaneous intrathoracic esophageal perforation. He was transferred to our hospital for further treatment. After arrival, he developed septic shock with acute respiratory failure. We considered that surgical treatment was too invasive and chose conservative treatment with an esophageal stent. Under general anesthesia, we first inserted a 20-Fr. trocar in the left posterior pleural space, and a large volume of the dark pleural effusion was discharged. We then performed endoscopy and found a pinhole perforation in the left posterolateral wall of the lower esophagus. We inserted both a silicon-covered esophageal stent with a check valve and a double elemental diet (W-ED) tube. We then inserted an 18-Fr. trocar into the left anterior wall. These procedures were performed less than 24 h after onset. As intensive medical care, the patient was administered broad-spectrum antibiotics and catecholamine. The two trocars and the W-ED tube were under continuous suction at − 5 cmH₂O and at − 20 cmH₂O every 30 s. On the 6th day, we inserted an additional thoracic drainage tube into the left pleura under CT guidance. The patient was discharged from the ICU to the general ward on the 7th day. We removed the stent almost triweekly, and the esophageal perforation was completely healed on the 45th day. He was discharged home on the 70th day.

Conclusion

Conservative treatment with a temporary self-expanding covered stent with a check valve, sufficient drainage, and W-ED tube nutrition was useful and effective in this unstable case of spontaneous intrathoracic esophageal perforation.

Laparoscopic Management of Boerhaave's syndrome: a case report with an intraoperative video

Background

Boerhaave’s syndrome involves a sudden elevation in the intraluminal pressure of the esophagus, causing a transmural perforation. It is associated with high morbidity and mortality. Its treatment is challenging, and early surgical intervention is the most crucial prognostic element.

Case presentation

We present a case of a 32 year-old male who presented after severe emesis with an acute onset of epigastric pain. He was diagnosed with Boerhaave’s syndrome. Displaying signs of shock mandated immediate surgical exploration with laparoscopic primary repair.

Conclusion

The golden period of the first 24 hrs of the event still applies to cases of esophageal perforation. The scarcity of these cases makes a comparison between the various treatment methods difficult. Our data support the use of laparoscopic intervention with primary repair as the mainstay of treatment for the management of esophageal perforation.

Multimodal Treatment Strategies for Esophageal Perforation

PURPOSE

Esophageal perforation constitutes a potentially life-threatening condition, and this study aimed to evaluate the indications and outcome for the different treatment modalities.

PATIENTS AND METHODS

In total, 43 patients with esophageal perforation were considered for this retrospective analysis. Age, sex, length of hospital stay and intensive care treatment, in-hospital mortality, localization of perforation and etiology, treatment modality, and 90-day morbidity were analyzed.

RESULTS

Most patients suffered from Boerhaave syndrome and from iatrogenic esophageal perforation. In total, 63% of patients (26/41) received successful nonoperative treatment, whereas 36% required additional surgery. Two patients (5%) underwent primary surgery. In all cases no esophagectomy was necessary. In-hospital mortality was 7%. During the 90-day follow-up 1 patient with stenosis required repetitive dilatations.

CONCLUSIONS

Initial endoscopic treatment, either by stent or by endosponge, alone or combined with an additional operative treatment, seems feasible in patients suffering from esophageal perforation. In all patients, there was no need for esophagectomy.

Treatment of spontaneous esophageal rupture (Boerhaave syndrome) using thoracoscopic surgery and sivelestat sodium hydrate

BACKGROUND

The mortality rate of spontaneous esophageal rupture remains 20% to 40% due to severe respiratory failure. We have performed thoracoscopic surgery for esophageal disease at our department since 1994. Sivelestat sodium hydrate reportedly improves the pulmonary outcome in the patients with acute lung injury (ALI).

METHODS

We retrospectively evaluated the usefulness of thoracoscopic surgery and perioperative administration of sivelestat sodium hydrate for spontaneous esophageal rupture in 12 patients who underwent thoracoscopy at our department between 2002 and 2014.

RESULTS

The patient cohort included 11 males and one female (median age, 61 years). The lower left esophageal wall was perforated in all patients. Surgical procedures consisted of thoracoscopic suture and thoracic drainage in six patients, transhiatal suture and thoracoscopic thoracic drainage in five, and thoracoscopic esophagectomy and thoracic drainage in one. The median time from onset to surgery was 8 hours with a surgical duration of 210 minutes, blood loss 260 mL, postoperative ventilator management 1 day, intensive care unit (ICU) stay 5 days, and interval to restoration of oral ingestion 13 days. Postoperative complications included respiratory failure in four patients, pyothorax in three, and leakage in one. There was no instance of perioperative mortality. Regarding perioperative administration of sivelestat sodium hydrate, the postoperative arterial oxygen partial pressure-to-fractional inspired oxygen ratio (P/F) and C-reactive protein (CRP) levels in the administration group were significantly better than those in the non-administration group on postoperative days 4 (P=0.035) and 5 (P=0.037), respectively. In contrast, there was no significant difference between the groups in median time of ventilator management, ICU stay, oral ingestion following surgery, or hospital stay.

CONCLUSIONS

Thoracoscopic surgery obtained acceptable results in all patients, including two with a significant time elapse from onset to treatment. Furthermore, sivelestat sodium hydrate was suggested to help improve postoperative respiration and inflammatory response.

Thoracoscopic primary repair with mediastinal drainage is a viable option for patients with Boerhaave's syndrome

Background

Spontaneous esophageal rupture (Boerhaave's syndrome) is an emergency that can cause life-threatening conditions. Various procedures have been used to treat Boerhaave's syndrome. However, a standard surgical procedure has not been established. Herein, we report our experience with primary suture of the ruptured esophagus via a thoracoscopy or laparotomy.

Methods

Between November 2002 and May 2015, 11 patients with Boerhaave's syndrome presented to our department and were managed using one of two surgical procedures based on the surgeon's discretion. Six patients underwent a thoracoscopic primary suture and drainage (group A); 5 patients underwent a primary suture via laparotomy followed by thoracoscopic drainage (group B). Patient medical records were retrospectively reviewed.

Results

The mean interval between initial perforation and surgery was 13.7 h (group A) and 17.2 h (group B) (P=0.7307). The mean operative time was 190 min (group A) and 249 min (group B) (P=0.106). Patient baseline characteristics and surgical outcomes were similar for both surgical procedures. One patient in each group experienced postoperative leakage that did not require surgical intervention.

Conclusions

The results suggest that thoracoscopic esophageal repair, as well as suturing via laparotomy, is a good surgical alternative for patients with Boerhaave's syndrome.

Two-tube method for treatment of spontaneous esophageal rupture and concomitant mediastinal infection

Objective

Spontaneous esophageal rupture (SER) is a rare but life-threatening condition with high mortality. The prognosis of patients with SER treated with surgical intervention or the traditional “three-tube” method is controversial. Thus, the aim of this study was to evaluate the clinical efficacy, feasibility, and safety of a new “two-tube” method involving a trans-fistula drainage tube and a three-lumen jejunal feeding tube for the treatment of SER without concomitant pleural rupture.

Methods

From January 2007 to June 2016, patients with SER and managed with the “two-tube” method or other methods were retrospectively analyzed. Data collected included initial presentation, procedure time, duration of treatment, numbers of patients with eventual healing of leaks, and complications.

Results

The average procedure time for the “two-tube” method was 22.1 ± 5.5 minutes. In comparison with the control method, the “two-tube” method had a similar diagnosis time (3.6 ± 1.4 vs. 3.4 ± 1.4 days) but a significantly higher successful closure rate (94.4% vs. 63.6%) and shorter treatment time (38.2 ± 5.6 vs. 53.6 ± 16.9 days). No complications associated with performance of the “two-tube” method occurred.

Conclusion

The “two-tube” method is an effective and safe approach for patients with SER.

Outcomes following the main treatment options in patients with a leaking esophagus: a systematic literature review

Leakage from the esophagus and gastroesophageal junction can be lethal due to uncontrolled contamination of the mediastinum. The most predominant risk factors for the subsequent clinical outcome are the patients' delay as well as the delay of diagnosis. Two major therapeutic concepts have been advocated: either prompt closure of the leakage by insertion of a self-expandable metal stent (SEMS) or more traditionally, surgical exploration. The objective of this review is to carefully scrutinize the recent literature and assess the outcomes of these two therapeutic alternatives in the management of iatrogenic perforation-spontaneous esophageal rupture as separated from those with anastomotic leak. A systematic web-based search using PubMed and the Cochrane Library was performed, reviewing literature published between January 2005 and December 2015. Eligible studies included all studies that presented data on the outcome of SEMS or surgical exploration in case of esophageal leak (including >3 patients). Only patients older than 15 years of age by the time of admission were included. Articles in other languages but English were excluded. Treatment failure was defined as a need for change in therapeutic strategy due to uncontrolled sepsis and mediastinitis, which usually meant rescue esophagectomy with end esophagostomy, death occurring as a consequence of the leakage or development of an esophagorespiratory fistula and/or other serious life threatening complications. Accordingly, the corresponding success rate is composed of cases where none of the failures above occurred. Regarding SEMS treatment, 201 articles were found, of which 48 were deemed relevant and of these, 17 articles were further analyzed. As for surgical management, 785 articles were retrieved, of which 82 were considered relevant, and 17 were included in the final analysis. It was not possible to specifically extract detailed clinical outcomes in sufficient numbers, when we tried to separately analyze the data in relation to the cause of the leakage: i.e. iatrogenic perforation-spontaneous esophageal rupture and anastomotic leak. As for SEMS treatment, originally 154 reports focused on iatrogenic perforation, 116 focused on spontaneous ruptures, and only four described the outcome following trauma and foreign body management. Only five studies used a prospective protocol to assess treatment efficacy. Regarding a leaking anastomosis, 80 reports contained information about the outcome after treatment of esophagogastrostomies and 35 reported the clinical course after an esophagojejunostomy. An overall success rate of 88% was reported among the 371 SEMS-treated patients, where adequate data were available, with a reported in hospital mortality amounting to 7.5%. Regarding the surgical exploration strategy, the vast majority of patients had an attempt to repair the defect by direct or enforced suturing. This surgical approach also included procedures such as patching with pleura or with a diaphragmatic flap. The overall reported success rate was 83% (305/368) and the in-hospital mortality was 17% (61/368). The current literature suggests that a SEMS-based therapy can be successfully applied as an alternative therapeutic strategy in esophageal perforation rupture.

[Diagnostic investigation in emergency medicine: Why case history is crucial]

We present the preclinical case of a patient reporting chest pain. Pain impeded physical examination. Reviewing the patient's detailed medical history after analgesia revealed a connection between the reported pain and vomiting. This led to a suspicion of organ perforation. Thus, the patient was admitted to a surgical emergency room (ER) and Boerhaave's Syndrome was diagnosed. After deterioration in the ER, cardiopulmonal reanimation (CPR), and successful surgical treatment, the patient was transferred to the intensive care unit (ICU) seven hours after first contact.

An unusual approach for the treatment of oesophageal perforation: Laparoscopic-endoscopic cooperative surgery

Boerhaave syndrome describes a transmural oesophageal rupture that develops following a spontaneous, sudden intraluminal pressure increase (i.e. vomiting, cough). It has a high rate of mortality and morbidity because of its proximity to the mediastinum and pleura. Perforation localisation and treatment initiation time affect the morbidity and mortality. In this article, we aim to present our successful laparoscopic-endoscopic cooperative surgery in a 59-year-old female who was referred to our clinic with a diagnosis of spontaneous lower oesophageal perforation. Laparoscopy and a simultaneous oesophageal stent application may be assumed as an effective alternative to conventional surgical approaches in cases of spontaneous lower oesophageal perforation.

Successful Management of Delayed Esophageal Rupture with T-Tube Drainage Using Video-Assisted Thoracoscopic Surgery

Spontaneous perforation of the esophagus after forceful vomiting is known as Boerhaave syndrome, a rare and life-threatening condition associated with a high rate of mortality. The management of Boerhaave syndrome is challenging, especially when diagnosed late. Herein, we report the successful management of late-diagnosed Boerhaave syndrome with T-tube drainage in a 55-year-old man. The patient was transferred to our institution 8 days after the onset of symptoms, successfully managed by placing a T-tube, and was discharged on postoperative day 46 without complications.

Thoracoscopic esophageal repair with barbed suture material in a case of Boerhaave's syndrome

A 53-year-old man was referred to our hospital with Boerhaave's syndrome. Thirty hours after onset, a left thoracoscopic operation was performed, with carbon dioxide pneumothorax and the patient in right semi-prone position. The thoracic cavity was copiously irrigated with physiological saline and a 4-cm longitudinal rupture was identified on the left side of the lower esophagus. The esophageal injury was repaired in 2 layers by using barbed absorbable suture material. The patient was allowed oral feeds after contrast esophagography confirmed the absence of contrast leak at the sutured site on postoperative day 7, and discharged by day 28. Suturing of the ruptured esophagus under thoracoscopic guidance is considered to be difficult and requires expertise. This case report demonstrates that the use of a barbed suture material simplifies thoracoscopic esophageal repair and also highlights the importance of pneumothorax and patient position in improving access to the esophagus.

Utility of endoscopic therapy in the management of Boerhaave syndrome

Background/aims: The optimal intervention for Boerhaave perforation has not been determined. Options include surgical repair with/without a pedicled muscle flap, T tube placement, esophageal resection or diversion, or an endoscopic approach. All management strategies require adequate drainage and nutritional support. Our aim was to evaluate outcomes following Boerhaave perforation treated with surgery, endoscopic therapy, or both. Patients and methods: We performed a 10-year review of our prospectively maintained databases of adult patients with Boerhaave perforations. We documented clinical presentation, extent of injury, primary intervention, "salvage" treatment (any treatment for persistent leak), and outcome. Results were analyzed using the Fisher's exact and Kruskal - Wallis tests. Results: Between October 2004 and October 2014, 235 patients presented with esophageal leak/fistula with 17 Boerhaave perforations. Median age was 68 years. Median length of perforation was 1.25 cm (range 0.8 - 5 cm). Four patients presented with systemic sepsis (two treated with palliative stent and two surgically). Primary endotherapy was performed for eight (50 %) and primary surgery for eight (50 %) patients. Two endotherapy patients required multiple stents. Median stent duration was 61 days (range 56 - 76). "Salvage" intervention was required in 2/8 (25 %) endotherapy patients and 1/8 (13 %) surgery patient (stent). All patients healed without resection/reconstruction. There were no deaths in the surgically treated group and two in the endotherapy group (stented with palliative intent due to poor systemic condition). Readmission within 30 days occurred in 3/6 of alive endotherapy patients (50 %) and 0/8 surgery patients. Re-intervention within 30 days was required for one endotherapy patient. Conclusion: Endoscopic repair of Boerhaave perforations can be useful in carefully selected patients without evidence of systemic sepsis. Endoscopic therapy such as stenting is particularly valuable as a "salvage" intervention. The benefits of endoscopic therapy and esophageal preservation are offset against an increased risk of readmission in patients primarily treated endoscopically.

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.

Primary closure of a spontaneous esophageal rupture under hand-assisted laparoscopy: a case report

Spontaneous rupture of the esophagus, which is also known as Boerhaave’s syndrome, is a rare life-threatening condition that requires urgent surgical management. The optimal treatment involves surgical repair of the esophageal defect, which is usually accomplished via laparotomy, thoracotomy, or both, and mediastinal debridement. Here, we report a case of spontaneous rupture of the esophagus that was treated with suturing repair and drain insertion using a hand-assisted laparoscopic approach.

The surgical management of spontaneous esophageal perforation (Boerhaave's syndrome) ‒ 20 years of experience

Spontaneous esophageal perforation (Boerhaave's syndrome) is an uncommon and challenging condition with significant morbidity and mortality. Surgical treatment is indicated in the large majority of cases and different procedures have been described in this respect. We present the results of a mono-institutional evaluation of the management of spontaneous esophageal perforation over a 20-year period. The charts of 25 patients with spontaneous esophageal perforation treated at the Surgical Department of the University Hospital of Lausanne were retrospectively studied. In the 25 patients, 24 patients were surgically treated and one was managed with conservative treatment. Primary buttressed esophageal repair was performed in 23 cases. Nine postoperative complications were recorded, and the overall mortality was 32%. Despite prompt treatment postoperative morbidity and mortality are still relevant. Early diagnosis and definitive surgical management are the keys for successful outcome in the management of spontaneous esophageal perforation. Primary suture with buttressing should be considered as the procedure of choice. Conservative approach may be applied in very selected cases.

Boerhaave Syndrome Presenting as Tension Pneumothorax: First Reported North American Case

Tension pneumothorax is a rare and potentially life-threatening clinical complication. A 43-year-old Caucasian woman with type 1 diabetes mellitus presented with nausea and retching and examination revealed dehydration. Laboratory parameters were consistent with a diagnosis of diabetic ketoacidosis, which responded to therapy. Suddenly, 30 hours later, she developed cardiorespiratory compromise due to a tension pneumothorax. After emergent decompression and catheter placement, computerized tomographic scan of the chest demonstrated esophageal-pleural fistula confirming Boerhaave syndrome as the etiology for the pneumothorax. The patient underwent emergent esophagectomy with pleural washout with a subsequent gastric pull-up surgery. Boerhaave syndrome frequently presents atypically with chest pain, dyspnea, and nausea. It communicates with the left pleural space in 80% to 90% of cases, but <5% of cases involve the right pleural cavity. Unexplained and rapidly progressive pleural effusions have been associated with this entity. Only 4 cases of Boerhaave syndrome causing tension pneumothorax have been reported in the literature so far.

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.

Successful surgical strategy in a late case of Boerhaave’s syndrome

Boerhaave’s syndrome refers to the spontaneous transmural rupture of the esophagus. Primary repair may be performed in patients who present within 24 h of perforation, and such cases have the best outcomes as most complications have not yet developed. However, the treatment of late perforations remains controversial. Various approaches and strategies to repair late perforations have been described in the literature, but there is no uniform approach. We present a case of Boerhaave’s syndrome in which the patient underwent surgical repair 48 h after the acute event and was subsequently treated successfully. The initial approach included direct esophageal repair, a drainage series, and nutritional support via a feeding jejunostomy. Although the repair site was subsequently disrupted, the patient showed complete healing of the perforation after three weeks. We consider that our surgical treatment strategy is safe and technically feasible, and appears to be a promising alternative approach for the treatment of patients with late Boerhaave’s perforation.
