ObjectiveTo summarize the recent development of surgical treatment for portal hypertension with hypersplenism. MethodsThe related literatures on various operation treatment of hypertension with hypersplenism at home and abroad in recent years were collected and reviewed. ResultsThere are many operation treatment methods of hypertension with hypersplenism, includes the pericardial devascularization, subtotal splenectomy, partial splenic embolization, spleen radiofrequency ablation, splenic artery ligation, distal splenorenal shunt, and so on. The different operation methods each has its advantages and disadvantages, but there are a certain percentage of the incidence of complications. At the same time, due to the limited understanding of the function of the spleen in portal hypertension, the treatment of "resecting" or "reserving" spleen has always been the hot spot of the academic dispute. ConclusionFor what kind of operation method is the most suitable for the treatment of hypertension with hypersplenism is no fixed conclusion.
Objective To study the protective effects of pre-storing glycogen on warm ischemia reperfusion injury during partial hepatectomy. Methods Thirty-eight patients were randomly divided into a trial group (n=19) and a control group (n=19). In the trial group, patients were given high concentration glucose intravenously during the 24 hours before the operation. The hepatic lesion was resected after portal triad clamping in the two groups. Liver function of all patients was measured before the operation and the first and fifth days after the operation. Normal hepatic tissue was biopsied to measured hepatic tissue glycogen contents before the operation and the change of superoxide dismutase (SOD) at the point of pre-ischemia, post-ischemia, and reperfusion 2 hour. Bcl-2 mRNA, a well known anti-apoptotic factor, was also detected using quantitative polymerase chain reaction. Results The hepatic tissue glycogen content of the trial group was significantly higher than that of the control group before the operation (Plt;0.01). Liver function of the trial group was significantly better than that of the control group on the first and fifth day after operation (Plt;0.05). There was significant difference in SOD activity between the two groups at the end of hepatic vascular occlusion and at the point of 2-hour reperfusion (Plt;0.05). Furthermore Bcl-2 mRNA expression of the trial group was notably up-regulated at the point of 2-hour reperfusion compared to the control group. Conclusion Pre-store storing glycogen might protect liver ischemia reperfusion injury caused by hepatic vascular occlusion during partial hepatectomy. The potential mechanism might be that pre-storing glycogen enhances Bcl-2 expression.

ObjectiveTo explore the risk factors for failure of enhanced recovery after surgery (ERAS) in partial hepatectomy. MethodsA retrospective analysis was performed on 344 patients who underwent partial hepatectomy at the Division of Liver Surgery, Department of General Surgery in West China Hospital of Sichuan University from January 2019 to December 2019. All patients were treated with ERAS after partial hepatectomy. Univariate and multivariate logistic regression analysis were used to evaluate the risk factors associated with failure of the ERAS after partial hepatectomy. ResultsA total of 344 patients were included in the study, including 44 patients in the ERAS failure group and 300 patients in the ERAS success group. Multivariate logistic regression showed that combined with chronic diseases [OR=2.32, 95%CI (1.07, 4.93), P=0.03] and intraoperative fluid replacement volume ≤2 475 mL [OR=2.16, 95%CI (1.06, 4.42), P=0.03] were risk factors for failure of ERAS. ConclusionChronic diseases and intraoperative fluid volume ≤2 475 mL are risk factors for the failure of ERAS after partial hepatectomy and can affect prognosis.
【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.
ObjectiveTo investigate the effectiveness of arthroscopic bipolar radiofrequency energy (bRFE) and lateral partial meniscectomy for lateral meniscus tear and cartilage lesion. MethodsBetween January 2011 and December 2012, 40 eligible patients with lateral meniscus tear and cartilage injury in the lateral knee compartment underwent arthroscopic treatment, and the clinical data were analysed retrospectively. There were 21 males and 19 females, aged 15-65 years (mean, 42.1 years). The left knee was involved in 22 cases and the right knee in 18 cases. The causes of injury included sport injuries in 5 cases and sprain of knee joints in 8 cases, the remaining patients had no history of trauma. The disease duration ranged from 1 month to 10 years (median, 10 months). The Lysholm score and Japanese Orthopaedic Association (JOA) score of the knee were 59.9±8.2 and 69.6±5.3. According to the Outerbridge classification, 2 cases were rated as grade I, 21 cases as grade II, 17 cases as grade III, and 10 cases as grade IV. The scores described by Noyes were 1-16 (mean, 6.52). The Noyes scores were from 1 to 6 points in 20 patients (group A) and 7 to 16 points in 20 patients (group B). During surgery, all patients underwent partial meniscectomy, and radiofrequency-based chondroplasty was used. Knee joint function was assessed using the Lysholm score and JOA score of the knee, and the clinical outcomes between different degrees of cartilage lesions were also compared. ResultsAll incisions healed primarily without complication. All the patients were followed up 8-31 months (mean, 18.1 months). The Lysholm and JOA scores of the knee at last follow-up (92.2±7.2 and 92.9±7.9, respectively) were significantly higher than those at preoperation (P<0.05). There was no significant difference in preoperative Lysholm and JOA scores of the knee between groups A and B (P>0.05), but significance difference was found between 2 groups at last follow-up (P<0.05). ConclusionArthroscopic bRFE and lateral partial meniscectomy have good effectiveness in treating lateral meniscus tear and cartilage lesion. The effectiveness is better in patients with mild cartilage lesion than in patients with severe cartilage lesion.
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.
