Caustic esophageal burn is a common ailment in clinical practice. In some patients, scar stricture was formed in the late stage of injury, and it seriously undermined quality of life of the patients. We adopted various clinical interventions at an early stage in order to relieve and alleviate the formation and development of corrosive esophageal stricture as a result of chemical injury as well as to avoid invasive operations to make it more acceptable for the patients. This article summarized the progress in etiology, pathological changes, identification, early prevention, and surgical management of corrosive esophageal stricture.

Various different objects have been reported to strangulate the penis. We reported on a patient who used metal radiator clamps for an extended period of time. Workup included history, physical examination and urinalysis. The patient was taken to the operating room for further evaluation with cystourethroscopy and orthopedic wire cutters were used to break the metal bands.

The related technology of enterostomy is a professional skill that colorectal surgeons need to master, and it is clinically important to prevent the occurrence of enterostomy-related complications of low rectal cancer. The early complications of enterostomy include stoma retraction, stoma ischemic necrosis, stoma edema and peripheral dermatitis, and the long-term complications include parastomal hernia, stenosis and stoma prolapse. In addition, the rare or easily neglected stoma cancer, difficulty of stoma closure and following social psychological disorders should also be paid attention to by surgeons. Effective reduction of enterostomy complications can lead to better quality of life for patients, which is the best interpretation of the concept of "patient-centered ness" by colorectal surgeons.

Objective: To study the clinical diagnosis and treatment strategies for vein-related pulsatile tinnitus patients with transverse sinus stenosis. Methods: The clinical data of patients with vein-related pulsatile tinnitus, from January 2015 to August 2019, were collected,whose digital subtraction angiography showing transverse sinus stenosis. Taking December 2019 as the last follow-up time, we analyzed the clinical characteristics, CT angiography and digital subtraction angiography results, lumbar puncture pressure and cerebrospinal fluid composition, and other auxiliary examination results (pure tone audiometry, fundus examination of papilledema, carotid ultrasonography, bone density screening, endocrinous test), as well as tinnitus handicap inventory, treatment options and follow-up results. Results: 83 patients were enrolled with female of 89.2% (74/83) and male of 10.8%(9/83); 65.1% (54/83) with right tinnitus, 31.3% (26/83) with left tinnitus, and 3.6% (3/83) with bilateral tinnitus; 67.5% (56/83) with right dominant sinus, 19.3% (16/83) with left dominant sinus, 13.3% (11/83) with bilateral equalization; Bilateral and ipsilateral stenosis accounted for 55.4% and 44.6% respectively; BMI was overweight or obese in 41 cases (49.4%, 41/83). Patients with tinnitus handicap inventory level three or above accounted for 79.5% (66/83). Eventually, 33 patients chose conservative observation (39.8%, 33/83), 40 patients (48.2%), 8 patients (9.6%) and 2 patients (2.4%) received sigmoid sinus-related surgery, interventional surgery, or emissary vein occlusion respectively. The mean follow-up time of 74 patients was 26.2 months. The data of 48 surgery patients showed that the pressure differences of venous sinus among the recurrent patients were more obvious; Interventional surgery with simultaneous stenting placement was effective. Tinnitus did not decrease in two patients with emissary vein occlusion. Analysis of 26 patients with lumbar puncture revealed eight cases of normal cranial pressure and 18 cases of high cranial pressure. The sinus pressure difference between the two groups was different (P=0.025), but the difference of age of onset, concomitant symptoms, BMI, proportion of empty sella or papilledema was not statistically significant (P>0.05). Conclusions: The evaluation of patients with vein-related pulsatile tinnitus requires a standardized procedure. Papilledema cannot be used as a sensitive indicator in patients with early intracranial hypertension. Venous sinus pressure difference may be one of the indicators of intracranial hypertension, and the lumbar puncture is the gold standard for the diagnosis. Weight loss can be used as a conservative treatment during the observation period. Significant sinus stenosis is a risk factor for recurrence in patients undergoing sigmoid sinus surgery. Interventional stenting is an effective treatment for tinnitus secondary to transverse sinus stenosis.

A case of high jejunal obstruction due to stricture is reported. It is a rare form of late sequelae of neonatal necrotizing enterocolitis(NEC). Barium contrast study of the small bowel is recommended for earlier diagnosis and treatment before discharge from the hospital, even is an asympto-matic patient.

A 11-year-old girl developed left main coronary artery osteal stenosis after Takayasu's arteritis for which she underwent Percutaneous Transluminal Coronary Angioplasty (PTCA). The narrowing of the left coronary artery was successfully dilated by angioplasty without apparent complication. This one suggests that PTCA may have a potential advantage as a temporary method to postpone the aortocoronary bypass surgery in a child with coronary artery stenosis due to Takayasu's arteritis.

OBJECTIVETo evaluate the feasibility, maneuver and efficacy of plasma prostate electrovaporization system in the treatment of rectal cicatricial stenosis.

METHODSAccording to similar procedure of transurethral resection prostate(TURP), intrarectal cicatriclectomy was performed with plasma prostate electrovaporization system in 7 patients with rectal low cicatricial stenosis after rectal cancer treatment (5 patients with transabdominal low anterior resection,2 patients with 3-dimension precise radiotherapy) to remove obstruction and dilate enteric cavity.

RESULTSSeven patients underwent 12 operations, including one operation in 3 patients, two operations in 3 patients, 3 operations in one patient. Resected rectal cicatricial tissue ranged from 5 to 15 g. Mean operation time was 41 min (25 to 40). Operation successful rate was 100% without complications such as perforation, bleeding and infection. All the patients had smooth defecation.

CONCLUSIONPlasma prostate electrovaporization system is an effective treatment for rectal cicatricial stenosis with tiny trauma.

OBJECTIVETo analyze the effect and safety of bronchoscopic cryosurgery in children with lower airway stenosis caused by granulation and fiber hyperplasia.

METHODTwenty-two patients had undergone bronchoscopic examination and cryosurgery, 18 patients with atelectasis caused by Mycoplasma pneumoniae pneumonia, 2 patients with endobronchial tuberculosis (EBTB), 1 patient with atelectasis caused by granulation tissue after bronchial foreign body, and 1 case who had severe dyspnea, with tracheal stenosis after long-term endotracheal intubation during surgery for heart disease. All the patients under went bronchoscopic cryosurgery for several times, 1 case with severe tracheal stenosis was operated by electric coagulation before cryosurgery. Before and after the treatment, all the patients were evaluated based on clinical symptoms, tracheal lumen by bronchoscopy, chest CT for atelectasis and pulmonary function for tracheal stenosis.

RESULTThe patients were treated with cryosurgery for 1-4 times. Sixteen cases were markedly improved, clinical symptoms disappeared completely, no granulation and fiber hyperplasia were found during bronchoscopy, and all the atelectasis were cured. After the treatment, the bronchial lumen diameter of the patient with tracheal stenosis was increased from 2 mm to about 5 mm, the tidal volume increased from 3.0 ml/kg to 8.8 ml/kg. Five cases were effectively improved, the clinical symptoms also disappeared, during bronchoscopy and bronchial alveolar lavage (BAL), no granulation and fiber hyperplasia were found, but some distal bronchial tubes were atresia or narrowed, the lumen was patent, the atelectasis recovered partially. In 1 case the treatment was ineffective, as the clinical symptoms and granulation disappeared, but because almost all distal bronchi were atresia or narrow, the lumen was not patent during BAL, there was no change on chest CT. The total effective rate was 21/22 (95.5%). No severe complications occurred during and after the procedures. All the patient were followed up for 1 - 12 months, no case had recurrence.

CONCLUSIONTreatment with bronchoscopic cryosurgery is a safe and effective methods to tracheal stenosis caused by granulation tissue and fiber hyperplasia in children.
