Reconstruction of hypopharyngeal and cervical esophageal defect after resection of hypopharyngeal carcinoma: a new technique based on the use of bilateral platysma myocutaneous flaps.

Commonly used procedures for reconstructing hypopharyngeal and cervical esophageal defects resulting from total laryngopharyngectomy (TL) are the gastric conduit or colon transposition as well as microvascularized free flaps. Herein we designed an alternative procedure utilizing bilateral platysma myocutaneous flaps (PMCFs) for the reconstruction of hypopharyngeal and cervical esophageal defects. This report summarizes the technical description of this procedure. TL and cervical esophagectomy were performed and bilateral PMCFs were harvested for reconstruction of hypopharyngeal and cervical esophageal defects in 25 patients aged between 46 and 73 years (mean 58.7 ± 16.2 years). All these patients had advanced-stage (IV) cancer with involvement of the cervical esophagus. Operative time ranged from 176 to 382 minutes (average 243 ± 91 minutes) and the mean intraoperative blood loss was 294 ± 119mL. There were six cases of anastomotic leak (24.0%) and two of them (8.0%) developed anastomotic stricture. Neither flap necrosis nor postoperative death was observed. The majority of our patients (68.0%) were restored to a normal unrestricted oral diet after surgery. The 3-year and 5-year actuarial survival rates were approximately 54.7% and 26.1%, respectively. We conclude that reconstruction of the cervical esophagus with bilateral PMCFs is a valuable method for treating advanced hypopharyngeal carcinoma.

Management of delayed intrathoracic esophageal perforation with modified intraluminal esophageal stent.

In this article, we reviewed our experience of treatment of the delayed intrathoracic nonmalignant esophageal perforation employing modified intraluminal esophageal stent. Between February 1990 and August 2006, eight patients were included in this study. Five patients experienced sepsis. The interval time between perforation and stent placement ranged from 36 h to 27 days (average, 8.6 days). Esophageal stenting and throracotomy for foreign body removal were performed in four patients. The remaining four patients underwent stent placement and thoracostomy. Nutrition was initiated through gastrostomy after 7 to 10 days after the stenting. The stent was removed after the patients resumed oral intake of food and the esophagogram showed that perforation was closed. There was no death in this group. Signs of sepsis remitted 1 week after stent placement. Complications included stress ulcer, stimulative cough, and pneumonia each. Stent removal ranged 32 to 120 days (average 66.7) after its placement. The stent was kept in place for 4 months to prevent formation of esophageal stricture in one patient with caustic esophageal burns. The follow-up was completed in all the patients. The mean follow-up period was 59 months (range 12-180). One patient with caustic esophageal burn underwent cicatricial esophagectomy and gastric transposition 3 years later due to the esophageal stricture. Barium swallow demonstrated that there was a diverticulum-like outpouching in one patient and slight esophageal stricture at T2 and T3 level in another. One patient developed reflux esophagitis 5 years after stent removal. All the patients finally had a normal intake of food. Modified esophageal stenting is an effective method to manage the delayed intrathoracic esophageal perforation. Prevention of stent migration and its convenient adjustment might be the major advantages of this method.

Prevention and management of complications after colon interposition for corrosive esophageal burns.

We present our experience in the management of complications after a colon interposition for corrosive esophageal burns. From April 1976 to December 2006, 85 patients with caustic esophageal burns were included in this study. The superior belly median incision with an anterior border incision of the left sternocleidomastoid was used. Anastomosis between the colon and the cervical esophagus was performed in 68 and between the colon and pharyngeal portion in 14 patients. An esophageal scar part resection and gastric-esophageal anastomosis was performed in one patient who had been given an unsuccessful colon and jejunum interposition at another institute. An anastomotic modeling operation was performed in one patient with anastomotic stricture who had been managed with colon interposition at another institute. Exploratory thoracotomy and gastrostomy was performed in one patient who had an unsuccessful colon interposition at another institute. Seven of 14 patients (8.5% of 17.1%) died with serious complications such as aspirated pneumonia, interposition colon necrosis, abdominal wound dehiscence and degradation of swallowing and concordance function. However, others with such serious complications survived and were discharged for rehabilitation after corresponding treatment. The 25 patients (30.1%) with other mild complications were discharged for rehabilitation and corresponding management. Two patients from other institutes were discharged for rehabilitation and one was lost to follow-up. The most dangerous complication of this procedure is colon necrosis, and the stomach is the best organ for re-operation. Otherwise, aspiration in infants due to hypoplasia and degradation of swallowing co-ordination needs attention. Peri-operative management is very important, including the control of mediastinal and pulmonary infection and systemic nutritional support to avoid abdominal wound dehiscence. The platysma flap is an excellent method for the treatment of anastomotic stricture.

Management of achalasia with transabdominal esophagocardiomyotomy and partial posterior fundoplication.

In this article we present our experience in the management of achalasia. From May 1988 through August 2005, 71 patients with achalasia underwent transabdominal esophagocardiomyotomy and partial posterior fundoplication. Barium swallow, manometry, and 24-h pH studies were performed in all patients preoperatively. Manometry and 24-h pH monitoring were only carried out in 58 patients at the third post-operative week and in 43 patients during follow-up, even though 52 patients were included in the follow-up. There were no operative deaths or complications. All the 71 patients were able to eat semifluid or solid food without dysphagia and heartburn at discharge. Esophageal barium studies showed that the maximum esophageal diameter decreased 2.2 cm and the minimum gastroesophageal junction diameter increased 8.4 mm after operation. Manometry examination in 58 patients revealed that the lower esophageal sphincter resting pressure decreased 15.0 mmHg in the wake of the procedure. Twenty-four hour pH monitoring demonstrated that reflux events were within the normal post-operative range. Fifty-five of the 58 patients had normal DeMeester scores. Among the patients with a mean 90-month follow-up, 49 patients had normal intake of food without reflux, the remaining three had mild dysphagia without requiring treatment. All the patients resumed their preoperative work and social activities. The manometry and 24-h pH studies in the 43 patients showed there were no significant changes between the third post-operative week and during follow-up. Transabdominal esophagocardiomyotomy and posterior partial fundoplication are able to relieve the functional outflow obstruction of the lower esophageal sphincter, obviate the rehealing of the myotomy edge and prevent gastroesophageal reflux in patients who have undergone myotomy alone.

[Tuberculosis of the breast].

Tuberculosis of the breast is a rare malady. The clinician may confuse tuberculosis of the breast with either carcinoma or breast abscess. In the past 30 years at the First Teaching Hospital attached to Xi'an Medical University, only 23 patients reported herein had documented tuberculosis of the breast. Tuberculosis of the breast is a disease of younger women between 20 and 40 years of age. Mammary tuberculosis may be primary or secondary. There are three recognized modes of spread of the tubercle bacillus to the breast: hematogenous, lymphatic spread, and direct extension. There are three recognized types of mammary tuberculosis: nodular, diffuse, and sclerosing type. The diagnosis of mammary tuberculosis is difficult. The most reliable diagnostic studies include bacteriologic cultures of aspirate, histologic examination of tissue, and guinea pig inoculation. The differential diagnosis includes with carcinoma, acute or chronic mastitis with abscess. The treatment of tuberculous mastitis requires a combination of surgery and antituberculous drugs.
