OBJECTIVETo analyze the factors related to sphincter preserving(SP) operation for lower rectal cancer.

METHODSClinicopathological data of 316 patients with lower rectal cancer 1-5 cm from the anorectal line who underwent surgical resection from Aug. 1994 to Nov. 2005 were analyzed. The whole period was divided into two period based on the introduction of TME in Jan. 1999. The SP rates, leakage between the two period were compared.

RESULTSThe SP rate increased significantly from 44.9 % in period I (Aug. 1994-Dec. 1998) to 76.2 % in period II (Jan. 1999-Nov. 2005)(P=0.000). The factors significantly influencing SP were the distance from the anorectal line, sex, period, circumference of intramural spread, histological differentiation (P< 0.05). Significant differences were detected between the two period in sex, volume of blood transfusion, Dukes' stage (P< 0.05). The rate of leakage were 2.7 % and 1.3 % in the two period (P > 0.05).

CONCLUSIONSOver 12 years, the SP rate of rectal cancers 1-5 cm from the anorectal line was significantly increased and volume of blood transfusion reduced obviously due to the introduction of TME. These surgical techniques, however, have no effect on the operating time and leakage rates.

A case of retrograde intussusception (acute type) of efferent limb into Braun side-to-side jejuno-jejunal anastomosis is presented. Intussusception, though infrequent, is well recognized complication after gastric surgery. Patient was 50 year old man who was admitted with epigastric pain and abdominal mass for 6 hours. Patient had a history of total gastrectomy 2 years before admission due to stage II gastric cancer. Seven hours after admission, hematemesis developed. Emergency fiberopticgastroscopy revealed type 4 jejunogastric intussusception. Segmental resection with end-to-end reanastomosis was performed.

A 7-year-old Thoroughbred gelding was admitted to Equine Hospital, Korea Racing Association for evaluation and treatment of colic. Based on the size and duration of the large colonic and cecal impaction, a routine ventral midline celiotomy and large colon enterotomy were performed to relieve the impaction. Six days following surgery the gelding exhibited signs of lethargy, fever, inappetence and diarrhea. Eleven days following surgery, the jugular veins showed a marked thrombophlebitis. On the sixteenth day of hospitalization the gelding died suddenly. Upon physical examination, the horse was febrile, tachycardic and tachypnoeic. Thoracic excursion appeared to be increased; however, no abnormal lung sounds were detected. No cough or nasal discharge was present. Hematology revealed neutrophilic leukocytosis. Serum biochemistry was normal but plasma fibrinogen increased. In necropsy, fibrinopurulent fluid was present in the thoracic cavity. There were firm adhesions between visceral pleura and thoracic wall. White, mixed and red thrombi were formed in both jugular veins from the insertion point of IV catheter. Histopathological examination showed fibrinopurulent inflammation and vascular thrombosis in the lung. The pleura showed edematous thickening and severe congestion. The clinicopathological and pathological findings suggest that septic thrombi associated with septic thrombophlebitis metastasized into the pulmonary circulation and were entrapped in the pulmonary parenchyma and provoked pleuropneumonia.

To investigate the feasibility and therapeutic effect of laparoscopy combined with total intersphincteric resection (Total-ISR) for extremely low rectal cancer.
 Methods: We performed laparoscopy combined with Total-ISR in 45 patients with extremely low rectal cancer (1.0 cm≤the lower edge of tumor to the anal edge≤3.0 cm) from January 2014 to December 2016. The operation time, blood loss, resection margin and overall incidence of postoperative complications were observed. The rate of local recurrence and distant metastasis after surgery during the median following-up time of 20.5 months were observed. Anal function at 3, 6, and 12 months after operation were compared.
 Results: The operation for 45 cases were successful without perioperative death. The operation time was (220±33) min and blood loss was (110±31) mL. The surgical margins were all negative. The incidence of postoperative complication was 6.7% (3/45) and no one suffered anastomotic leakage. After a median follow-up of 20.5 (6-30) months, 2 cases developed local recurrence and 1 case developed distant metastasis. According to Kirwan grade, the grade II was 24.4% (11/45), grade III was 57.8% (26/45) in 3 months after operation, and the grade II increased to 51.1% (23/45), the grade III decreased to 35.5% (16/45) after 6 months. Seven out of 40 patients in 12 months after operation reached the grade I, and 25 patients reached the grade II. There were significant differences between 3 months and 6 months, 6 months and 12 months after operation (P<0.05) in the anal function situation.
 Conclusion: It is feasible, for appropriate patients, to perform laparoscopic combined with total-ISR, especially for the patients with extremely low rectal cancer that were in early stage without invasion to the extemal sphincter. The procedure has the advantages of radical sphincter-saving, minimal invasion and economy.

OBJECTIVE: To investigate the efficacy of Coblation-channelling for the tongue(CCT) treatment of tongue hypertrophy. METHOD: The 31 patients with severe obstructive sleep apnea hypopnea syndrome (OSAHS) combining tongue hypertrophy staged as Friedman ll or N were performed CCT after nasal septum surgery, coblation channelling of bilateral inferior turbinate and coblation-assisted UPPP. While the vertical channelling in the base and the body of the tongue, the tilted one parallel side edge and posterior to the tongue were combined. The intraoperative and postoperative complications such as bleeding were observed. The 12 months postoperative follow-up were done by MRI of the tongue. RESULT: The retrolingual space were expanded postoperatively. The 2 bleedings occurred immediately after channellings in the tongue body, and they were stopped by local compression. No postoperative tongue paralysis, no tongue hematoma and abscess happened. The tongue sizes changed from preoperative III or IV degree to postoperative I to II degrees. One case received three CCT sessions. CONCLUSION CCT treatment tongue hypertrophy is a individually safe, effective and minimally invasive treatment.

OBJECTIVETo evaluate the different pathological and clinical characteristics of thymomas with and without myasthenia gravis (MG) and to determine whether the presence of MG influences the prognosis in thymoma patients.

METHODSThe clinical data from 228 consecutive patients (median sternotomy were used in 153, video-assisted thoracoscopic themectomy were used in 75) operated on from January 1992 to December 2007 was analyzed retrospectively. These thymoma patients had been subdivided into two groups: thymoma with MG (n = 125) and thymoma without MG (n = 103). All thymic epithelial tumors were classified according to the WHO histologic classification and the Masaoka clinical staging system. The result was evaluated according to the Myasthenia Gravis Foundation of America's criterion. The clinical features of the 2 test was compared between the two groups by χ² test, and the survival were compared between the two groups by Cox analysis.

RESULTSThere were no peri-operative deaths. 19 cases were inoperable (6 in the group with MG, 13 without MG (χ² = 4.52, P = 0.035)). The proportions of type A and thymic carcinoma were 0 in the group with MG, 10.5% (11/103) and 11.6% (12/103) respectively in the group without MG. According to the Masaoka's clinical staging, in the group MG, 24.8% (31/125) patients were stage III and IV; in the group without MG, 33.0% (34/103) patients were stage III and IV. There was a significant difference between hyperplastic paraneoplastic thymus coexisting in 28.8% (36/125) patients with MG and only 5.8% (6/103) in patients without MG (χ² = 20.91, P = 0.000) Microthymoma was identified in the paraneoplastic thymus of 3 patients with MG. There were 198 patients followed up, the rate was 86.8% (198/228). There was no recurrence in patients with type A and a few patients with type AB, B1, B2, B3 thymoma and thymic carcinoma recurred. The actuarial 5- and 10-year survival rates were 89.3% and 81.2% for patients with MG respectively, and 90.0% and 78.9% for patients without MG respectively. Within 5 years postoperatively, 6 of 9 patients with MG died of myasthenia crisis, while 6 out of 7 deaths in patients without MG were attributable to inoperable tumors (stage IV) and thymic carcinoma.

CONCLUSIONSThe existence of myasthenia gravis has little influence on the prognosis of thymomas, but it is good for early diagnosis and treatment. Extended thymectomy should be performed to all patients with thymoma, no matter they have myasthenia gravis or not. The main cause of death is myasthenia crisis for thymoma patients with MG and stage IV and (or) thymic carcinoma for patients without MG.

BACKGROUND: The endoscopic transnasal approach has been proven to have advantages on the removal of the tumors in pterygopalatine fossa (PPF) and infratemporal fossa (ITF). Herein, this study aimed to describe a modified approach for resection of the tumors in these areas, both in cadaveric specimen and clinical patients. METHODS: The 20 adult cadaveric specimens and five patients with tumors in PPF and ITF were enrolled in this study. For the cadaveric specimens, ten were simulated anterior transmaxillary approach and ten were performed modified endoscopic transnasal transmaxillary approach. The exposure areas were compared between two groups and main anatomic structure were measured. Surgery was operated in the five patients with tumors of PPF and ITF to verify the experience from the anatomy. Perioperative management, intraoperative findings and postoperative complications were recorded and analyzed. RESULTS: The modified endoscopic transnasal transmaxillary approach provided as enough surgical exposure and high operability to the PPF and ITF as the anterior transmaxillary approach did. The diameter of maxillary artery in the PPF was 3.77 ± 0.78 mm (range: 2.06-4.82 mm), the diameter of middle meningeal artery in the ITF was 2.79 ± 0.61 mm (range: 1.54-3.78 mm). Four patients who suffered schwannoma got total removal and one of adenocystic carcinoma got subtotal removal. The main complications were facial numbness and pericoronitis of the wisdom tooth. No permanent complication was found. CONCLUSIONS With the widespread use of neuroendoscopy, the modified endoscopic transnasal transmaxillary approach is feasible and effective for the resection of tumors located in PPF and ITF, which has significant advantages on less trauma and complications to the patients.
