【Abstract】 Objective To compare the short-term effects of arthroscopic partial meniscectomy in treating medial versuslateral meniscus injuries. Methods From January 2003 to January 2006, 207 patients with meniscus injury(without intraarticularligament injury) underwent arthroscopic partial meniscectomy. The medial meniscus injury group included 115 cases, 50males and 65 females; aged 14 to 78 years(mean 46.9 years); 66 left knees and 49 right knees. Twenty-six cases had injury histories,the delayed time from injury to surgery ranged from 6 d to 6 months (mean 2.1 months). The lateral meniscus injury group included92 cases, 18 males and 74 females; aged 16 to 62 years (mean 41.1 years); 57 left knees and 35 right knees. Twenty-four caseshad injury histories, the delayed time from injury to surgery ranged from 9 d to 6 months (mean 1.9 months). Lysholm score systemwas applied and the scors of pre- and post-operation and were compared between two groups. Results The period of followupranged from 12 to 45 months (mean 31.5 months). In medial meniscus injury group and lateral meniscus injury roup, theLysholm score increased from 61.3±16.9 and 57.4±17.6 preoperation to 95.0±7.9 and 93.3±7.4 postoperation respectively. Therewas statistically significant difference between preoperation and postoperation (P lt; 0.01), and there was no statistically significantdifference between two groups(P gt; 0.05). The excellent and good rates for function of knee joint were 97.39% (excellent in 107cases, good in 5 cases and fair in 3 cases) in medial meniscus injury group and 100%(excellent in 80 cases and good in 12 cases)in lateral meniscus injury group. Conclusion Arthroscopic partial meniscectomy is a safe and effective treatment for meniscusinjury, there is no diference in short-term effects in treating medial versus lateral meniscus injuries.
To evaluate the biological tolerance of the human liver to prolonged warm ischemia, 20 patients who underwent liver resections with hepatic inflow occlusion are reported. Biopsy of liver were performed during and after consecutive periods of hepatic ischemia, and speciments were observed under light and electron microscope. The results showed that hepatic vascular occlusion for <30 min, resulted in atotissular temporary but reversible pathologic and ultrastructural changes in liver, even patients with liver cirrhosis had better recovery from the operation when the hepatic ischemia was lengthen up to 40 min.

The detection rate of benign and borderline/low-grade malignant tumors of pancreas has increased year by year. Most of the patients are middle-aged and young people, who have thirst for high quality of life in long-term. Pancreatic-duct-preserving partial pancreatectomy can meet the needs of reducing surgical trauma, preserving normal pancreatic function and improving patients’ quality of life. However, pancreatic-duct-preserving partial pancreatectomy often needs to face the problem of pancreatic duct defect. Repair of pancreatic duct needs to be applied according to different types of pancreatic duct defect. At the same time, the prevention and treatment of pancreatic fistula also require more patience, courage and creativity of pancreatic surgeons. Pancreatic-duct-preserving partial pancreatectomy can solve the current clinical problems. It is safe and feasible with carefully evaluate indications, characters of patients and the personal ability of surgeons.
Thirty-six partial hepatectomies for patients with symptomatic intrahepatic stones is reported.Partial liver resection should be done when the liver containing strictrue(s),dilated ducts and stones.Meanwhile,additional procedures should be performed togather with partial hepatectomy,i,e,common duct exploration and drainage,cholangiotomy and cholangioplanty,and cholangeoenterostomy,according to the location of stones and ductal strictures.Postoperative long-term follow-up in this series showed that the results of 86.2% of patients were satiffactory.Partial hepatectomy can be considered as a better treatment of choice for the stones confined to one segment or lobe of liver or combined with multiple strictures of ducts.
ObjectiveTo objectively evaluate the effectiveness of the ventricular fold pull-down combined with strip myofascial flap to repair laryngeal defect after early glottic carcinoma operation with glottic morphological parameters and voice parameters. MethodsBetween January 2008 and December 2012, 47 patients with early glottic carcinoma and anterior commissure involvement underwent partial laryngectomy. All patients were male, aged from 60 to 75 years (mean, 68.5 years). The disease duration was 4-11 months (mean, 7.2 months). According to American Joint Committee on Cancer (AJCC) TNM criteria, 28 cases were classified as T1aN0M0, 14 cases as T1bN0M0, and 5 cases as T2N0M0. Laryngeal defect after resection of tumor was repaired by ventricular fold pull-down combined with strip myofascial flap. At 1 day before operation and at 1 year after operation, multilayer spiral CT was used to scan larynx, to measure and compare the anteroposterior diameter of vocal area, the distance between both sides of the vocal process, and the thickness of soft tissue of vocal area, and the effect of combined soft tissue flap was objectively assessed in laryngeal morphology reconstruction. The actual voice parameters[including F0, Jitter, Shimmer, normalized noise energy (NNE), and maximum phonatory time (MPT)] were tested and compared, and the effect of the combined soft tissue flap on postoperative laryngeal pronunciation was evaluated. ResultsPostoperative pathological examination revealed well-differentiated squamous cell carcinoma in 38 cases, and moderately-differentiated squamous cell carcinoma in 9 cases; no tumor was found in the resection margin. Healing of neck incision was obtained in all patients at 7-9 days after operation. Forty-four cases were decannulated at 9-11 days after operation and the remaining 3 cases were decannulated at 3 weeks after operation. Oral feeding usually started in all cases at 3-4 days after operation. All patients were followed up 1 year. At 1 year after operation, the anteroposterior diameter of vocal area was significantly reduced when compared with preoperative one (t=15.161, P=0.000); the distance between both sides of the vocal process and the thickness of soft tissue of vocal area had no significant changes (P > 0.05). Compared with preoperative ones, there were significant differences in Shimmer, NNE, and MPT (P < 0.05), but no significant difference was found in F0 and Jitter (P > 0.05) at 1 year after operation. ConclusionVentricular fold pull-down combined with strip myofascial flap can repair laryngeal defect effectively after partial laryngectomy and maintain the effective airway after operation. It not only has no effect on postoperative laryngeal morphology, but also can be used as new laryngeal voice vibration body.
