Transverse rectus abdominis myocutaneous flap for postpneumonectomy bronchopleural fistula: A case report.

RATIONALE: Numerous types of flap coverage have been reported to prevent or to repair bronchopleural fistulas. Most of the flaps were harvested from chest area. However, these pedicled flaps might not be optimal for the patient who has undergone previous radiotherapy on pulmonary parenchyma because the pedicle artery of the flap might have been injured by irradiation. Therefore, an alternative flap outside of the chest area is necessary. PATIENT CONCERNS: A 61-year-old male was diagnosed of squamous cell carcinoma in right upper lobe lung (cT3N2M0, stage IIIa). After completing the neoadjuvant chemoradiotherapy, he underwent video-assisted thoracoscopic surgery with right side intrapericardial pneumonectomy. DIAGNOSIS: Persistent air leak due to postpneumonectomy bronchopleural fistula. INTERVENTIONS: Pedicled transverse rectus abdominis myocutaneous (TRAM) flap was used to repair the bronchial stump. OUTCOMES: The bronchial stump was repaired successfully, the bronchopleural fistula was obliterated, and the patient was free from air leak after following for 12 months. LESSONS: This case demonstrated that pedicled TRAM flap is a feasible alternative to repair bronchopleural fistula.

Video-assisted thoracoscopic surgical decortication in the elderly with thoracic empyema: Five years' experience.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) with decortication is a major treatment for thoracic empyema in the fibropurulent stage. Compared to open thoracotomy, VATS decortication has similar efficacy but fewer postoperative complications in the treatment of thoracic empyema. The role of VATS decortication in the elderly had rarely been investigated. METHODS: From January 2006 to August 2011, we retrospectively enrolled 33 patients older than 65 years diagnosed as thoracic empyema and treated with VATS decortication. We analyzed the outcomes of this geriatric population, including surgical effectiveness, postoperative morbidity, and mortality. RESULTS: A total of 33 patients with mean age of 73.6 ± 7.1 years received VATS decortication for their empyema. Twenty-one (63.6%) patients were male. Only one patient died of progressive sepsis, due to pulmonary infection 9 days after VATS decortication. The 30-day mortality was 3% after the surgery. The major etiology (87.9%) of thoracic empyema was pneumonia. The main causes of postoperation morbidity included respiratory failure requiring mechanical ventilation for >7 days (15.2%) and septic shock (15.2%), followed by persistent air leakage for >7 days (9.1%). Twenty-four (75%) of 32 patients had good re-expansion of the affected lung 3 months after VATS decortication. CONCLUSION: We concluded that VATS decortication in the treatment of thoracic empyema is effective in elderly patients. The major concerns of postoperative complications are respiratory failure and sepsis.

Bacteriology of acute appendicitis and its implication for the use of prophylactic antibiotics.

BACKGROUND: To prevent surgical site infection (SSI) after appendectomy, antibiotic prophylaxis has been recommended for all patients, but this approach is based largely on bacteriologic findings that are decades old. The objective of this study was to reevaluate the bacteriology of acute appendicitis in order to assess the usefulness of current antibiotic prophylaxis. METHODS: Between January 1 and December 31, 2010, 117 patients with pathology-proved acute appendicitis were recruited. Antibiotic prophylaxis was given according to national guidelines. Immediately after operation, the luminal contents of the appendices were swabbed for bacterial culture. The charts of the patients were surveyed retrospectively for postoperative complications until June 30, 2011. RESULTS: Bacteria were isolated from 115 of 117 specimens sent for culture (98%). Of the 115 samples that yielded bacteria, all gave rise to aerobic isolates and five yielded mixed aerobic and anaerobic isolates. The most common aerobic organism was Escherichia coli, which was present in 100 of 117 patients who had pathology-proved acute appendicitis (85%). Less frequent organisms were Klebsiella pneumoniae (30 cases; 26%), Streptococcus spp. (29 cases; 25%), Enterococcus spp. (21 cases; 18%), and Pseudomonas aeruginosa (18 cases; 15%). All P. aeruginosa isolates were sensitive to amikacin, ceftazidime, and cefepime; but seven of the eight were resistant to cefuroxime. Eight patients were identified as having had a postoperative SSI, and P. aeruginosa was isolated from five of these cases. The isolation of P. aeruginosa correlated significantly with SSI (p=0.002). CONCLUSIONS: The most commonly identified aerobic bacteria associated with acute appendicitis were E. coli, followed by K. pneumoniae, Streptococcus, Enterococcus, and P. aeruginosa. Pseudomonas aeruginosa frequently was not covered by the prophylactic antibiotics chosen and might be associated with SSI.

Gastric schwannoma.

Gastrointestinal mesenchymal tumors are a group of tumors originated from the mesenchymal stem cells of the gastrointestinal tract, consisting of gastrointestinal stromal tumors (GIST), leiomyomas or leiomyosarcomas or schwannomas. Gastric schwannoma is a very rare gastrointestinal mesenchymal tumor, which represents only 0.2% of all gastric tumors and 4% of all benign gastric neoplasms. We report a 24-year-old girl who suffered from an episode of upper gastrointestinal bleeding. The endoscopic examination showed a round submucosal tumor with a central ulceration and bleeding over the high body of the stomach. Surgical resection of the tumor was performed. The pathological examination revealed a picture of spindle cell tumor that was strongly positive for S-100 protein stain, and non-reactive for CD34, CD117, actin, HHF-35, desmin, melan-A and HMB-45, consistent with gastric schwannoma. The literature is reviewed.

Surgical results of squamous cell carcinoma of the esophagus in young patients.

BACKGROUND: Squamous cell carcinoma of the esophagus (ESCC) is one of the ten most common cancers in Taiwan. Surgical resection is the mainstay of the treatment. Young patients with ESCC are reported to have poor surgical outcome. This retrospective and comparative study is to evaluate the clinicopathologic difference and survival between young and elderly patients. METHODS: From January 1985 to December 2000, totally 797 patients with esophageal cancer received esophagectomy with reconstruction at our institution. Among them, 12 patients who received neoadjuvant concurrent chemo-radiotherapy followed by esophagectomy were excluded from this study. The other 785 patients were divided into two groups. Group I included 67 patients aged 50 or younger (8.5%) and group II included 718 patients aged over 50 years (91.5%). The clinical data were collected by chart review and follow-up data were collected through outpatient department record or telephone contact. These two groups were analyzed and compared regarding sex ratio, exposure to tobacco or alcohol, surgical mortality rate and 5-year survival rate. RESULTS: There was no difference in gender distribution between young and old patients groups. More patients in the young patients group had the habits of alcohol and tobacco consumption than in the elder patients group. The surgical (30-day) mortality was 2.98% in the young patient group, and 5.43% in the elder group. The 5-year survival rate was better in young patients group than in elder patients group but there was no statistical significance. Survival in young patients group was significantly related to TNM staging system. CONCLUSIONS: More young patients with ESCC had the habit of smoking and drinking. There was no statistical difference between the groups in clinical variables, surgical mortality and survival. The survival rate was significantly related to the TNM tumor stage.
