Minimally invasive Ivor-Lewis esophagectomy for esophageal cancer

BACKGROUND

In this study, we present our minimally invasive Ivor-Lewis esophagectomy technique and survival rates of this technique.

METHODS

Between September 2013 and December 2020, a total of 140 patients (56 males, 84 females; mean age: 55.5±10.3 years; range, 32 to 76 years) who underwent minimally invasive Ivor- Lewis esophagectomy for esophageal cancer were retrospectively analyzed. Preoperative patient data, oncological and surgical outcomes, pathological results, and complications were recorded.

RESULTS

Primary diagnosis was esophageal cancer in all cases. Minimally invasive Ivor-Lewis esophagectomy was carried out in all of the cases included in the study. Neoadjuvant chemoradiotherapy was administrated in 97 (69.3%) of the cases. The mean duration of surgery was 261.7±30.6 (range, 195 to 330) min. The mean amount of intraoperative blood loss was 115.1±190.7 (range, 10 to 800) mL. In 60 (42.9%) of the cases, complications occurred in intraoperative and early-late postoperative periods. The anastomotic leak rate was 7.1% and the pulmonary complication rate was 22.1% in postoperative complications. The mean hospital stay length was 10.6±8.4 (range, 5-59) days and hospital mortality rate was 2.1%. The median follow-up duration was 37 (range, 2-74) months and the three- and five-year overall survival rates were 61.8% and 54.6%, respectively.

CONCLUSION

Minimally invasive Ivor-Lewis esophagectomy can be used safely with low mortality and long-time survival rates in esophageal cancer.

Thoracic perforations-surgical techniques

Esophageal perforation may occur spontaneously, iatrogenically or in connection with traumas. Sepsis may develop in connection with mediastinal and pleural exposure in a very short time as a consequence of disintegration of the esophagus. Esophageal perforation is an emergency accompanied with a high level of mortality and morbidity. Rate of mortality for the perforations in the thoracic region is higher than that in the cervical and abdominal regions. Delay in diagnosis and treatment is the most important factor to affect the mortality. A quick and true diagnosis of esophageal perforation is prerequisite for a successful treatment. There is no certain consensus in relation with the optimal treatment of that life-threatening condition. However, in the event that perforation is detected early in a healthy esophagus, then primary repair is recommended. When it is detected late, nonoperative conservative treatment would be appropriate. The rates of mortality for the operations following a period of 24 h after rupture formation are higher than 50%. Esophagectomy is a type of an operation that is to be considered in the event of an end stage benign esophageal disease or of a large esophageal damage that does not allow primary repair. Significant decrease has been observed in the morbidity and mortality of esophageal perforation due to the improvements in the endoscopical techniques today. Minimally invasive techniques, in which drug eluting stents come first, will become an important step for the treatment of esophageal perforations in the forthcoming years.

The increasing incidence of esophageal squamous cell carcinoma in women in Turkey

BACKGROUND/AIM

This study assessed the trend changes in the histological types of esophageal cancer in a 25-year period in eastern Turkey.

MATERIALS AND METHODS

We searched all cases of esophageal cancer from 1990 to 2015 according to their histological diagnosis and sex, grouping the patients in 5-year time periods to evaluate time trends.

RESULTS

We identified 1462 cases of esophageal cancer. In terms of patient make-up, 742 were male and 720 were female. In general, 75.86% of the patients had squamous cell carcinoma (SCC), 19.56% of the patients had adenocarcinoma (ADC), and the remaining 4.58% patients were found to have other histopathologic disorders. While the SCC to ADC ratio was 1.76 between 1990 and 1994, this rate increased to 8.73 between 2010 and 2014; during these periods, the male to female ratio decreased from 1.43 to 0.86. Between these two periods, statistically significant changes were observed of SCC and the number of female patients (P < 0.001, P = 0.008, respectively).

CONCLUSION

While the incidence of esophagus ADC and the number of male patients increased recently in Western countries, the number of female patients and SCC cases increased in our region in the last 25 years.

Primary Endoscopic Repair of a Large Tracheal Rupture Through Tracheal Stoma

We describe the case of an 83-year-old man who presented with a large trauma to the membranous wall of the trachea and was treated with endoscopic primary repair of the tracheal wall through a preexisting tracheal stoma. Assessment with an optical telescope through the tracheal stoma revealed a 5-cm laceration in the membranous wall of the trachea starting immediately above the carina. The laceration was closed using continuous 4-0 monofilament polydioxanone sutures with direct visualization of tissues through a fiberoptic telescope. This approach is particularly effective in cases of traumatic rupture of the membranous trachea.

The use of self-expandable metallic stents for palliative treatment of inoperable esophageal cancer

Most patients with esophageal carcinoma present in the advanced stage die from tumor invasion and widespread metastases. Because radical regimens are not appropriate for the majority of patients, and their expected survivals are as short as to be measured by months, the main aim of therapy is palliation with minimum morbidity and mortality. Among the palliative modalities are surgery, external radiotherapy or brachytherapy, dilatation, laser, photodynamic therapy, bipolar electrocoagulation tumor probe, and chemical ablation. The placement of self-expandable metallic stents is another method that improves dysphagia for these patients. In this study, the aim was to evaluate retrospectively the effectiveness of metallic stents deployed because of inoperable malignant esophageal stenosis and esophagotracheal fistulas. The results of 170 patients with 202 stents administered because of inoperable malignant esophageal stenosis and esophagorespiratory fistula between January 2000 and October 2008 at the Ataturk University, Department of Thoracic Surgery, were investigated. Despite epidemiological and clinical data, information regarding relief of dysphagia and quality of life were also examined. One hundred seventy patients with stents were between 28 and 91 years old (mean age 63.7 years+/-11.4 years). Ninety-seven were male and 73 were female. Stent indications were advanced tumors with distant metastasis (82 cases, 48.2%), unresectable tumors (51 cases, 30%), patients who cannot tolerate surgery or chemoradiotherapy (18 cases, 10.5%), local recurrence after primary therapy (1 case, 0.5%), esophagorespiratory fistulas from tumor or therapy (14 cases, 8.2%), and refusal of surgery (4 cases, 2.3%). Dysphagia scores evaluated by a modified Takita's grading system improved from 3.4 before the procedure to 2.6 afterward. The overall complication rate without chest pain was 31.7% (occurring in 64 cases). Mean survival was 177.7 days+/-59.3 days (2-993 days). Quality-of-life scores (The European Organization of Research and Treatment of Cancer QLQ C30) improved from 73+/-10.3 (57-85) to 112+/-12.6 (90-125). In therapy of malignant esophageal obstructions, metallic stents provide a significant improvement in dysphagia and require less frequent re-intervention according to other methods of dysphagia palliation such as dilatation, laser, and photodynamic therapy, nearly completely relieve esophagotracheal fistulas and improve quality of life to an important degree.

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.

Follicular thyroid carcinoma: metastasis to the sternum, 13 years after total thyroidectomy

Primary and metastatic malignancies of the sternum are uncommon. Secondary lesions to the sternum occur more commonly in patients with lung and breast cancer, and only a few cases of sternal metastasis arising from a follicular thyroid carcinoma have been reported in the literature. Rarely, metastases to the sternum present in the guise of primary sternal tumours may be treated surgically with that diagnosis in mind. We describe a case of a sternal mass treated by radical surgery, which ultimately proved to be a solitary metastasis from a follicular carcinoma of the thyroid, appearing 13 years after total thyroidectomy and radioactive iodine therapy. Late metastatic thyroid carcinoma to the sternum should be kept in mind in the differential diagnosis of sternal lesions. For patients with thyroid carcinoma and sternal metastasis, we recommend surgical resection of the metastasis, not only as a curative or palliative measure but also to maximise the effect of subsequent radioiodine treatment.

Extraskeletal Ewing sarcoma of the diaphragm presenting with hemothorax

Ewing sarcoma is a relatively uncommon malignant bone neoplasm that usually occurs in children and young adults and involves the major long bones, pelvis, and ribs. Primary diaphragmatic Ewing sarcoma is extremely rare. To the best of our knowledge, only three cases of primary Ewing sarcoma of the diaphragm have been reported. A 12-year-old girl presented spontaneous occurrences of the right hemothorax. After drainage, a roentgenogram film, computed tomography, ultrasonography, and magnetic resonance image showed a giant mass on the right diaphragm. Primary diaphragmatic tumor was resected totally by right posterolateral thoracotomy, and histologically, an extraskeletal Ewing sarcoma was identified. The patient received adjuvant radio-chemotherapy, and there was no evidence of disease 10 months after the operation. Although extremely rare, extraskeletal Ewing sarcoma should be kept in mind in the differential diagnosis of diaphragmatic soft tissue tumors.

Esophageal perforation: the importance of early diagnosis and primary repair

Esophageal perforation is associated with high morbidity and mortality rates, particularly if not diagnosed and treated promptly. Despite the many advances in thoracic surgery, the management of patients with esophageal perforation remains controversial. We performed a retrospective clinical review of 36 patients, 15 women (41.7%) and 21 men (58.3%), treated at our hospital for esophageal perforation between 1989 and 2002. The mean age was 54.3 years (range 7-76 years). Iatrogenic causes were found in 63.9% of perforations, foreign body perforation in 16.7%, traumatic perforation in 13.9% and spontaneous rupture in 5.5%. Perforation occurred in the cervical esophagus in 12 cases, thoracic esophagus in 13 and abdominal esophagus in 11. Pain was the most common presenting symptom, occurring in 24 patients (66.7%). Dyspnea was noted in 14 patients (38.9%), fever in 12 (33.3%) and subcutaneous emphysema in 25 (69.4%). Management of esophageal perforation included primary closure in 19 (52.8%), resection in seven (19.4%) and non-surgical therapy in 10 (27.8%). The 30-day mortality was found to be 13.9%, and mean hospital stay was 24.4 days. In the surgically treated group the mortality rate was three of 26 patients (11.5%), and two of 10 patients (20%) in the conservatively managed group. Survival was significantly influenced by a delay of more than 24 h in the initiation of treatment. Primary closure within 24 h resulted in the most favorable outcome. Esophageal perforation is a life threatening condition, and any delay in diagnosis and therapy remains a major contributor to the attendant mortality.

Solitary eosinophilic granuloma of sternum

Primary bone tumors of the chest wall are uncommon, although a wide variety of both benign and malignant tumors arise within the chest wall. Among those tumors, sternal tumors are rare and usually malignant. We report an extremely rare case of eosinophilic granuloma developed in the sternum in a 30-year-old woman. She presented anterior chest pain and somewhat tender mass over the sternum. Chest roentgenogram, computed tomography scanning of the thorax, and total body bone scintigraphy revealed an isolated lytic lesion in the corpus sterni. A tru-cut biopsy of the mass exhibited the typical histologic appearance of eosinophilic granuloma. The solitary lesion was removed completely surgically. This rare condition should be kept in mind in differential diagnosis of sternal lesions.

Combination of paraesophageal hernia and Morgagni hernia in an old patient

Paraesophageal hiatal hernia is an uncommon condition that requires urgent correction to prevent life-threatening complications. It is present in 14% of all hiatal hernias. The incidence of Morgagni hernia among all diaphragmatic defects is 3-4% and about 90% of the hernias occur on the right, 8% are bilateral and 2% are on the left. The combination of a Morgagni hernia and paraesophageal hernia is very rare and only four cases have been reported in the literature. All of them occurred in the right. This report describes an old case admitted to our clinic with dyspnea, chest pain and chronic gastrointestinal symptoms, found to have combined left Morgagni and paraesophageal hernia. Surgical repair was performed via transabdominal approach. This unusual case and surgical approaches are discussed in light of the data presented in the literature.

Tracheobronchial foreign bodies: a 10 year experience

BACKGROUND

Our aim is to describe foreign body aspiration in the tracheobronchial tree, a common emergency with serious consequences.

METHODS

We reviewed the records of 357 patients who were admitted to our hospital during a 10-year period for the treatment of aspirated foreign body into the tracheobronchial tree.

RESULTS

Of these cases, 42.4% were male and 57.6% female. Their ages ranged from 4 months to 70 years (average of 10.8 years). The most common manifestation was coughing, with subsequent dyspnea and wheezing. All underwent rigid bronchoscopy for the removal of the foreign body. Foreign bodies were localized in the right bronchial tree in 188 cases (52.7%), the left in 107 cases (30%) and trachea in 39 cases (10.9%). Foreign bodies were not found during bronchoscopy in 23 cases (6.4%). The foreign bodies were: needles (n=125), peanuts (n=110), plastic objects (n=52), and miscellaneous (n=47). Foreign bodies were removed by bronchoscopy in all but six cases (1.7%), who underwent limited thoracotomy. The present series had a mortality of 0.56 percent (two deaths) following removal of foreign body.

CONCLUSIONS

Foreign body aspiration are rapidly recognized from the patient's history and easily treated by bronchoscopy and extraction of the aspirated foreign body. A high index of suspicion is crucial for early diagnosis. However, education is the best preventive measure for decreasing the incidence of this matter.

Spontaneous esophageal rupture following severe vomiting in pregnancy

Spontaneous esophageal perforation is an uncommon finding requiring prompt diagnosis and immediate surgery because of its high mortality rate. Esophageal rupture secondary to severe vomiting in pregnancy is extremely rare and only four cases have been published in the literature. We report the case of a 20-year-old female in whom severe vomiting in early pregnancy resulted in esophageal perforation with subcutaneous emphysema. The diagnosis was made 48 h later. The patient had undergone surgical treatment and the postoperative period was uneventful. The unusual cause and the interesting clinical course of esophageal rupture are described.

Primary hydatid cysts of the mediastinum

Hydatid disease remains a serious health problem for the Mediterranean countries, such as Turkey. Living in a rural area is an important risk factor for the disease. Hydatid cysts are usually located in the liver, lung, and brain. Mediastinal hydatid disease is very rare that have been only anecdotally in the literature. The objective of this study was to evaluate the clinical and radiographic findings and surgical treatment of this unusual lesion. Between 1985 and 2002, 11 cases with primary mediastinal hydatid cyst were treated surgically at our clinic. Median age was 28.4 and ranged from 19 to 46 years. Symptoms included chest pain in nine patients (82%), and cough in six patients (54%). The cyst was located in the anterior mediastinum in four patients (36%), in the posterior mediastinum in five patients (45%) and in the middle mediastinum in two patients (18%). All cysts were intact except one cyst that ruptured into right intrapleural space. Surgical approach was right thoracotomy in five patients (45%), left thoracotomy in three patients (27%), and median sternotomy in three patients (27%). Total pericystectomy was chosen as the surgical procedure in all patients except four (36%), who had cystectomy and local curettage for cyst located vital structures. There were no complications and mortality postoperatively. Primary hydatid cysts of the mediastinum are distinct clinical entity that must be considered when caring for a patient with a mediastinal mass in endemic regions. Because of surrounding vital structures the cyst should be treated without delay.

Esophageal tuberculosis abscess: an unusual cause of dysphagia

Primary esophageal tuberculosis is extremely rare. It is almost always secondary to tuberculosis of other organs. Abscess formation of the tuberculosis in the esophageal wall has not been reported in the literature previously. In this report, we present a case of esophageal tuberculosis abscess, with presented dysphagia, diagnosed by histologic evaluation of surgery specimen, without any other organ involvement. The unusual cause and the interesting clinical course of dysphagia are described.

Breast mass caused by rib tuberculosis abscess

Tuberculosis involving ribs and presenting with breast mass is a very rare entity and only a few cases have been reported in the literature previously. A 35 year-old patient had a retromammarial abscess revealed by a mass in the medial quadrant of right breast. Midsternal incision for abscess drainage and a partial resection of involved ribs was performed. Histopathologic evaluation revealed rib tuberculosis and secondary abscess formation in the right breast. This unusual manifestation of tuberculosis should be included in differential diagnosis of high-risk patients presenting with a breast mass.

Primary leiomyosarcoma of the anterior mediastinum

Primary mediastinal leiomyosarcoma are extremely rare tumors, which develop from smooth muscle, usually in the esophagus or main vessels. Very few cases have been reported in the literature and only two of these developed from small vessels in the soft tissue of the anterior mediastinum. We report on a 45-year-old man who presented with a huge anterior mediastinal tumor. The tumor was surgically removed with right thoracotomy and the diagnosis of well-differentiated leiomyosarcoma was established. It probably originated from the anterior mediastinal tissue, so at operation a continuity was not found between the tumor and neighboring structures. This rare and interesting histopathology is discussed and the literature is reviewed.
