Surgery in thoracic esophageal perforation: primary repair is feasible

Prompt diagnosis and effective treatment are important for thoracic esophageal perforations. The decision for proper management is difficult especially when diagnosed late. However, there is an increasing consensus that primary repair provides good results for repair of thoracic esophageal perforations, which are not diagnosed on time. Primary repair for thoracic esophageal perforations was applied in 20 out of 25 consecutive patients. The time interval between perforation and repair was less than 24 h in six patients (group I), and more than 24 h in 14 patients (group II). The remaining five patients underwent esophagectomy with simultaneous or staged reconstruction because of incorrectable underlying esophageal pathology. Group I had much more iatrogenic causes (P < 0.05). Preoperative sepsis occurred only in group II (P=0.05) and was highly associated with Boerhaave syndrome (P=0.001). Regional viable tissue was used to reinforce the sites of primary repair (n=15, 75%). All of the postoperative morbidity (n=9, 45%) including esophageal leaks (n=6, 30%) and operative death (n=1, 5%) occurred in group II. In patients with postoperative leaks, five eventually healed, but one became a fistula that required reoperation. Primary healing with preservation of the native esophagus was achieved in all 19 patients except one operative death. In addition, the increased incidence of leak and morbidity did not lead to an increase in mortality. In the esophagectomy group, there was no mortality, but one minor suture leak. Regardless of the time interval between the injury and the operation, primary repair is recommended for non-malignant, thoracic, esophageal perforations, but not for anastomotic leaks. Reinforcement that may change the nature of a possible leak is also useful. For incorrectable underlying esophageal pathology, esophagectomy with simultaneous or staged reconstruction is indicated.     

Successful endoscopic hemoclipping of an esophageal perforation

We describe a case of esophageal perforation that resulted from a fishbone. A 71-year-old man had had a fishbone impacted in the lower esophagus for 2 days. At presentation, the bone was dislodged at endoscopy; one round opening in a deep ulceration was detected when the fishbone was removed. The perforation was closed by endoscopic hemoclipping, after the removal of the fishbone. A thoracic computed tomography revealed air around the esophagus, aorta and bronchus and the presence of a pleural effusion. These findings suggested mediastinal emphysema and mediastinitis due to the esophageal perforation after the removal of the fishbone. Esophagography revealed a focal esophageal defect and linear contrast leakage at the distal esophagus. The mediastinal emphysema and pleural effusion successfully resolved after the endoscopic hemoclip application and conservative management of the perforation.     

Successful endoscopic repair of an unusual colonic perforation following polypectomy using an endoclip device

Colonic perforation during endoscopic diagnostic or therapeutic procedures,represents an uncommon occurrence even if,together with haemorrhage,it is still the most common complication of colonoscopy,with an incidence ranging between 0.1% and 2% of all colonoscopic procedures. The ideal treatment in these cases remains elusive as the endoscopist and the surgeon have to make a choice case by case,depending on many factors such as how promptly the rupture is identified,the condition of the patient,the degree of contamination and the evidence of peritoneal irritation. Surgical interventions both laparotomic and laparoscopic,and other medical non-operative solutions are described in the literature. Only three cases have been reported in the literature in which the endoscopic apposition of endoclips was used to repair a colonic perforation during colonoscopy. Ours is the first case that the perforation itself was caused by the improper functioning of a therapeutic device.     

Angioplasty of pedicled right gastroepiploic artery graft through a six French diagnostic catheter

Pedicled right gastroepiploic artery is increasingly being used as a conduit for coronary artery bypass surgery. We describe an interesting case in which balloon angioplasty for stenosis in such a graft was performed through a 6 French diagnostic catheter.     

Successful treatment of a saphenous vein graft perforation with an autologous vein-covered stent.

A 52-year-old man with a history of prior coronary bypass surgery suffered recurrent angina and underwent percutaneous placement of a stent within the midportion of the saphenous vein graft to the marginal branch of the left circumflex coronary artery, which was complicated by a significant perforation. The perforation was successfully closed using an NIR stent covered with a segment of autologous antecubital vein. Subsequent surgical exploration confirmed successful closure of the perforation.

Perioperative outcomes of esophagectomy preceded by the laparoscopic transhiatal approach for esophageal cancer

This study was designed to determine the efficacy of esophagectomy preceded by the laparoscopic transhiatal approach (LTHA) with regard to the perioperative outcomes of esophageal cancer. The esophageal hiatus was opened by hand‐assisted laparoscopic surgery, and carbon dioxide was introduced into the mediastinum. Dissection of the distal esophagus was performed up to the level of the tracheal bifurcation. En bloc dissection of the posterior mediastinal lymph nodes was performed using LTHA. Next, cervical lymphadenectomy, reconstruction via a retrosternal route with a gastric tube and anastomosis from a cervical approach were performed. Finally, a small thoracotomy (around 10 cm in size) was made to extract the thoracic esophagus and allow upper mediastinal lymphadenectomy to be performed. The treatment outcomes of 27 esophageal cancer patients who underwent LTHA‐preceding esophagectomy were compared with those of 33 patients who underwent the transthoracic approach preceding esophagectomy without LTHA (thoracotomy; around 20 cm in size). The intrathoracic operative time and operative bleeding were significantly decreased by LTHA. The total operative time did not differ between the two groups, suggesting that the abdominal procedure was longer in the LTHA group. The number of resected lymph nodes did not differ between the two groups. Postoperative respiratory complications occurred in 18.5% of patients treated with LTHA and 30.3% of those treated without it. The increase in the number of peripheral white blood cells and the duration of thoracic drainage were significantly decreased by this method. Our surgical procedure provides a good surgical view of the posterior mediastinum, markedly shortens the intrathoracic operative time, and decreases the operative bleeding without increasing major postoperative complications.     

Successful sealing of perforation of saphenous vein graft by coronary stent.

Coronary artery perforation is a rare occurrence during angioplasty and could lead to major complications requiring emergency surgical intervention. We describe a case of perforation of a saphenous vein graft during stenting. The perforation was successfully sealed by a second coronary stent.     

Successful management of esophageal perforation due to an aortic arch aneurysm replacement

SUMMARY.  We present the successful management of an esophageal perforation after aortic arch aneurysm replacement in a 64-year-old patient. Four weeks after surgical repair of a perforated aortic arch aneurysm, a contained perforation of the thoracic esophagus on the prosthesis was detected. A subtotal esophagectomy and reconstruction by pull-up of the stomach together with the greater omentum and high intrathoracic esophagogastrostomy was performed. The aortic prosthesis was covered by omentum. After a prolonged postoperative course, the patient was discharged from the hospital on a full oral diet. She is well after 1 year without signs of infection.     

Successful management of esophageal perforation using a removable self-expanding covered metallic stent after endoscopic submucosal dissection for a patient with a history of gastrectomy

An 81-year-old man with esophageal perforation after endoscopic submucosal dissection, who had a history of distal gastrectomy and had undergone endoscopic submucosal dissection for high-grade intraepithelial dysplasia at another hospital, suddenly developed epigastric pain at night after vomiting. Computed tomography showed pneumomediastinum and bilateral pleural effusions indicating esophageal perforation. The initial doctor referred the patient to our department. On arrival, the patient was in septic shock with acute respiratory failure. It was considered that he was unable to undergo aggressive surgical treatment safely, and a stent with a silicone cover and check valve was placed. Drainage tubes were then inserted into the mediastinum and each thoracic cavity, and a double elementary diet tube was inserted for nutrition and decompression of the stomach. The stent was removed on the 26th day, and the perforation was cured. Stent insertion is a useful treatment for the patient with serious esophageal perforation after ESD with a history of gastrectomy.     

Endoscopic closure of tympanic membrane anterior perforation using a strip-type chondroperichondrial graft

Myringoplasty is a surgical procedure to reconstruct tympanic perforation. However, repair of anterior perforations is still challenging. To analyze the anatomical and hearing outcomes of myringoplasty with a new technique of chondroperichondrial graft via endoscopy, 23 adult patients were retrospectively analyzed. All patients had anterior perforations of tympanic membranes that were repaired with a composite strip-type cartilage-perichondrium graft through a total endoscopic transcanal approach. The anatomical graft success rate at postoperative 1 month was 86.96% (20/23) and reached 100% at the 6- and 12-month follow-up. Compared to the preoperative air conduction threshold (44.7 ± 13.56 dB) and air-bone gap (ABG) (22.35 ± 6.54 dB), the postoperative air conduction threshold and ABG decreased to 33.52 ± 10.88 dB and 12.52 ± 3.94 dB, respectively (P < .0001). Twenty-two (95.65%) patients had an ABG below 20 dB postoperatively. The mean ABG improvement in our cohort was 9.83 ± 5.00 dB. The functional graft success rate was 95.65% (22/23). The convenience, reliability, time, and labor savings accrued from the approach described here make it a good choice for repair of anterior perforation of tympanic membrane.     

Successful treatment of coronary artery perforation during angioplasty using a new membrane-coated stent

We report a case of successful treatment of coronary artery perforation and cardiac tamponade, which developed during percutaneous transluminal coronary angioplasty, with a PTFE-coated stent. Intravascular ultrasound was first used to overcome the shortcomings of conventional angiography and overlapping of a conventional stent was not as effective as coated-stent placement in sealing a further leakage. Thus, PTFE-coated stents may be an effective alternative to emergency surgery or autologous venous covered stenting and should be considered when coronary artery perforation occurs.     

Successful closure of coronary artery perforation using non-conventional embolic material

Coronary perforation during percutaneous coronary interventions is a rare but dreadful complication. While coronary perforation involving large vessels are managed successfully by covered stents, small distal vessel perforation is usually managed by prolonged balloon inflation or embolization of gel foam/thrombogenic metallic coils. We describe a case, where perforation of a small ventricular branch of the right coronary artery was successfully occluded by packing it with pieces of thrombogenic floppy tips of used coronary angioplasty guidewires instead of conventional metallic coils.     

Endoscopic repair of a colonic perforation following polypectomy using an endoclip.

Endoscopic repair using an endoclip device for colonic perforation following polypectomy is described. This is the first case report of a repair following a regular polypectomy-induced perforation described in the English literature.     

Successful closure of spontaneous esophageal perforation (Boerhaave's syndrome) by endoscopic clipping.

Endoscopic clips have been used mainly for control of gastrointestinal (GI) bleeding and occasionally for closure of GI perforations. However, closure of spontaneous esophageal perforation (Boerhaave's syndrome) by clipping has not been reported. We described successful non-surgical closure of spontaneous esophageal perforation by endoscopic clipping in a patient with bilateral pyopneumothorax and septicemia.
