Abstract： Objective To summarize the technical characteristics and experience on the surgical treatment of esophagobrochial fistula induced by esophageal carcinoma and explore the safe and effective operation procedures. Methods This report retrospective1y summarized 12 cases of esophagobronchial fistula induced by esophageal cancer between January 2007 and November 2010 in Tangdu Hospital, Fourth Military Medical University. There were 9 male patients and 3 female patients with their mean age of 51.24 years (ranging from 37 to 62 years). Four types of surgical procedures were performed to patients according to their respective conditions: (1) Esophagectomy ＋“tunnel”esophagogastrostomy ＋ pulmonary lobectomy (2 patients)； (2) Esophagectomy ＋ stapled esophagogastrostomy ＋ pulmonary lobectomy (5 patients)； (3) Esophagectomy ＋ colon interposition for esophagus ＋ pulmonary lobectomy (4 patients)； (4) Esophagectomy ＋ esophagogastrostomy ＋ left pneumonectomy (1 patient). Results Among those 12 cases presenting to our hospital, 2 patients died during the postoperative period and the overall morality was 16.67%(2/12). One patient died of acute congestive heart failure on the 4th postoperative day after esophagectomy, “tunnel”esophagogastrostomy and left lower lobectomy of the lung for esophageal carcinoma directly invading the left lower bronchus, and another patient died of severe infection and renal failure on the 11th postoperative day after esophagectomy, stapled esophagogastrostomy and left upper lobectomy of the lung for esophageal carcinoma directly invading the left upper bronchus. Four patients developed mild empyema and 1 patienthad bronchial fistula after surgery, who finally recovered and were discharged after treatment of antibiotics and drainage. The postoperative morbidity was 41.67%（5/12）. All surviving patients were followed up from 1 month to 3 years. During follow-up, there was one death, and the other patients were alive without any clinical events. Conclusion Individualized surgical procedure is a safe and effective therapeutic choice for patients with esophagobronchial fistula induced by esophageal carcinoma.
ObjectiveTo investigate clinical characteristics and surgical treatment of patients with non-malignant esophageal-tracheal/bronchial fistula.?Methods?We retrospectively analyzed clinical data of 12 patients with non-malignant esophageal-tracheal/bronchial fistula who underwent surgical repair in Peking Union Medical College Hospital from January 2002 to October 2011. There were 6 males and 6 females with a mean age of 49.8 years (ranging from 32 to 72 years). There were 7 patients with esophagotracheal fistula，1 patient with esophagobronchial fistula，2 patients with gastro-bronchial fistula after esophagectomy for esophageal cancer，and 2 patients with esophageal diverticulum bronchial fistula. Nine patients underwent surgical repair via right thoracotomy approach，and 3 patients via left thoracotomy approach. Seven patients underwent esophageal fistula and tracheal fistula repair，1 patient underwent esophageal fistula and bronchial fistula repair，2 patients underwent gastric fistula and bronchial fistula repair，1 patient underwent esophagectomy, gastroesophageal anastomosis and left lower lobectomy, and 1 patient underwent esophageal diverticulum repair and left lower lobectomy.?Results?All the patients recovered well from surgery with no perioperative complication or in-hospital death，and resumed oral intake 7-10 days after surgery. Three months to 1 year postoperatively, regular examinations including upper gastroenterography and fibrobronchoscopy found no sign of tracheal/bronchial stenosis or esophageal stenosis，and no patients needed stent implantation or dilatation treatment. All the patients were followed up from 3 months to 10 years and had a good quality of life during follow-up.?Conclusion?Excluding malignant etiology and determining the exact fistula location are key points of clinical diagnosis for esophageal-tracheal/bronchial fistula. Adequate preoperative nutritional support and 1-stage surgical repair can lead to satisfactory clinical outcomes.
Abstract： Objective To investigate the change of tissue structure and epithelial barrier function of excluded esophagus after esophageal exclusion surgery for tracheoesophageal fistula (TEF). Methods Twentyeight hybrid dogs were divided into 3 groups with random number method. For group A (n=12), fistula was excluded; for group B (n=12), only the esophagus was excluded; and group C (n=4) was the control group. The normal and excluded esophagus of the three groups were observed through general sampling, HE staining, transmission electron microscope (TEM), scanning electron microscope (SEM) and Lanthanum trace labeling. The interstitial space dilation (ISD) of the cells on the esophageal mucosa was measured and the number of desmosome in the intercellular space was calculated. Results The changes of tissue structure and epithelial barrier function of the excluded esophagus were similar between group A and group B. Compared with group C, group A and B showed the following changes: esophageal structure changed, submucous glandular tissues reduced or disappeared; the interstitial space increased, the number of desmosome decreased, and the epithelial barrier function attenuated, but the basal lamina did not changed and lanthanum did not break through it. For the dogs in group C, esophageal mucosa could be observed, submucosa was complete and a large number of gland tissues and micrangiums could be seen in it. The number of desmosome for group A, B and C was 0.21±0.03 entries/μm2, 0.22±0.05 entries/μm2, and 0.32±0.03 entries/μm2 respectively, which showed a significant difference between group A, B and group C (Plt;0.05), while there was no significant difference between group A and group B (Plt;0.05). The average interstitial space for group A, B and C was 2.11±0.56 μm, 2.04±0.77 μm, and 1.84±0.49 μm respectively. There was no significant difference between group A and B, while there was significant difference between group A, B and group C. Conclusion The esophageal exclusion surgery for refractory TEF is safe, feasible, and effective with few complications, and deserved to be popularized.
Objective To investigate safety and short-term effect of subtotal hepatectomy with caudate lobe as sole remnant liver in treatment of hepatolithiasis, and to analyze diagnosis and treatment process of bronchobiliary fistula after hepatectomy. Methods The clinical data of 1 patient with hepatolithiasis combined with liver atrophy-hypertrophy syndrome and caudate lobe with compensatory hypertrophy who was admitted to the Gansu Provincial People’s Hospital in August 2016 were analyzed retrospectively. The body surface area of the patient was 1.47 m2, the standard total liver volume was 1 040 cm3. According to the results of CT, the expected residual 1iver volume (caudate lobe volume) after the hepatectomy was 643 cm3, and the ratio of residual liver volume over the standard total liver was 61%. The patient received the subtotal hepatectomy with the caudate lobe as the sole remnant liver and T tube drainage. The follow-up including the postoperative complications and recurrence of calculus was performed by the regular hospital check up till September 2017. Results The subtotal hepatectomy with caudate lobe as sole remnant liver was performed successfully. The operative time and intraoperative blood loss were 280 min and 3 000 mL, respectively. The peritoneal drainage tube was removed on the 8th postoperative day with a good recovery of liver function. The postoperative pathological examination showed that there were some intrahepatic bile duct pigment stones, the bile duct wall fibrous tissue hyperplasia combined with a focal liver cells hydropic degeneration, and no canceration. The patient was discharged on the 40th postoperative day. Two months later, the T tube cholangiography showed that the inferior extremity bile duct was unobstructed and there was no residual intra- and extra-hepatic stone. The liver function was normal, then the T tube was removed. After 6 months, the patient coughed and exhausted the bilious sputum, meanwhile the sputum culture showed that there were the Escherichia coli and Streptococcus viridans, then the bronchobiliary fistula was diagnosed. After the multidisciplinary discussion, the patient received the right thoracocentesis and double abdominal drainages around liver, meanwhile, combined with the anti-inflammatory, liver protection, intravenous nutrition support, etc., the bilious sputum was obviously reduced. So far, the patient had been followed up for one year, the patient's cough, and expectoration symptoms disappeared and his condition was stable. Conclusions Caudate lobe-sparing subtotal hepatectomy in treatment of hepatolithiasis is safe and feasible, but it is possible that bronchobiliary fistula is followed after operation, individual and multidisciplinary collaboration in treatment of bronchobiliary fistula caused by extensive hepatectomy is safe and feasible.
