Methods: Laparoscopic subtotal cholecystectomy was performed when the cystic duct cannot be identified safely, such as empyema cholecystitis, Mirris syndrome, frozen Calot’triangle, shrunken gallbladder. The operation consists of resecting the anterior wall of the gallbladder, removing all stones, and placing a large drain. 41 patients who underwent a laparoscopic subtotal cholecystectomy between 1 January 2003 and 31 October 2008 were retrospectively analyzed. Results: Fortyone cases of complex laparoscopic cholecystectomy were performed. 1 cases in which were changed to open cholecystectomy. Operating time was 45145 min, average (57.42±19.41) min. 1 cases were reoperated because of the bile leak. Hospital stays were 27 days. Conclusion: Laparoscopic subtotal cholecystectomy is a viable procedure during cholecystectomy in which Calot’s triangle cannot be safely dissected. It may simplify the operation and decrease the risk in complicated cholecystectomy and averts the need for a laparotomy.
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 verify the feasibility and effectiveness of the modified fast-track surgery (FTS) in the perioperative period of open liver resection. Methods A prospective randomized controlled trial was carried out in 188 consecutive patients undergoing open liver resection between March and December 2014 in the Department of Liver Surgery of West China Hospital. The modified fast recovery procedure and standard rehabilitation procedure were compared in terms of length of hospital stay after operation, hospitalization cost, complications and readmission rate. Results A total of 188 consecutive patients were enrolled in the trial. The analysis included 87 patients in the modified fast recovery group and 89 in the standard rehabilitation group. Compared with the standard rehabilitation group, the modified fast recovery group had a shorter length of hospital stay [(5.70±1.47)vs. (7.26±1.96) days] and a lower cost [(42.7±6.7)vs. (47.3±12.5) thousand yuan], and the differences were statistically significant (P<0.05). There were 20 complication cases in the modified group and 39 in the standard group with significant difference (P=0.003). There was no significant difference in the rate of readmission between the two groups (P=1.000). Compared with the standard group, patients in the modified group had less pain 8 hours, the 1st and 2nd days after surgery, better postoperative activities of daily living, more initiative cough times and off-bed activity times, longer duration of movement, and earlier bowel recovery and exhausting, and all the above differences were significantly different (P<0.05). Stepwise regression analysis showed that postoperative complications and bowel recovery and exhausting time were independent related factors for postoperative hospital stay (P<0.001). Conclusions Multimodal analgesia-based fast recovery procedure is feasible and effective in the perioperative period of partial hepatectomy. It can shorten the time of hospitalization and reduce the cost of hospitalization.
ObjectiveTo compare postoperative efficacy of thoracoscopic partial pneumonectomy with or without thoracic drainage tube postoperatively.MethodsThe PubMed, Wanfang database, CNKI and Web of Science from January 2000 to August 2020 were searched by computer to collect randomized controlled studies (RCT), cohort studies and case-control studies on the efficacy of chest drainage tube placement versus no placement after thoracoscopic partial pneumonectomy. Two reviewers independently screened articles and extracted data to evaluate the risk of literature bias. Meta-analysis was performed with RevMan software.ResultsA total of 15 articles were included, including 1 RCT and 14 cohort studies. A total of 1 524 patients were enrolled, including 819 patients in the test group (no postoperative chest drainage tube group) and 705 patients in the control group (postoperative chest drainage tube group). Compared with the control group, the length of hospital stay in the test group was shorter (MD=–1.3, 95%CI –1.23 to –0.17, P<0.000 01) and the incidence of postoperative pneumothorax was higher (RD=0.06, 95%CI 0.01 to 0.10, P=0.01). There was no significant difference between the two groups in operation time (MD=–2.37, 95%CI –7.04 to 2.30, P=0.32), the incidence of postoperative complications (RR=2.43, 95%CI 0.79 to 1.80, P=0.39), the reintervention rate of postoperative complications (RD=0.02, 95%CI=–0.00 to 0.04, P=0.05), postoperative subcutaneous emphysema (RD=0.02, 95%CI –0.01 to 0.06, P=0.20) and the incidence of postoperative pleural effusion (RD=0.04, 95%CI –0.00 to 0.09, P=0.10) .ConclusionCompared with the patients with chest drainage tube placement after thoracoscopic partial pneumonectomy (the control group), the test group can shorten the hospital stay. Although the incidence of postoperative pneumothorax is higher than that of the control group, the operation time, incidence of postoperative subcutaneous emphysema and in-hospital complications, and reintervention rate of in-hospital complications are not statistically significant between the two groups. Therefore no chest drainage tube may be placed after partial pneumonectomy.
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.
ObjectiveTo improve the calculation method of the sum of residual hepatic lobe volume and total liver volume after partial hepatectomy in rats.MethodsOne hundred and thirty-five SD rats of different body sizes were divided into five groups by completely random design. The body length, tail length, chest circumference, body weight and length of hepatic triangle lobe of the rats were measured before surgery. Then, according to the classic Higgins and Anderson methods, different lobectomies of liver were performed for each group: middle lobe + left inner lobe, left outer lobe, bilateral papillary lobe, triangular lobe, and right lateral lobe were removed; the proportion of theoretical liver resection in each group was 38.1%, 30.1%, 7.9%, 7.8% and 15.3%, respectively. The actual liver resection volume and residual liver volume were measured after surgery. we finally analyzed statistical differences of liver volume calculated by different indirect methods. In addition, the correlation analysis and regression analysis were conducted between the preoperative measured rat body surface parameters and the measured whole liver volume, so as to explore a more simple and accurate volume measurement method.ResultsThe actual proportion of liver resection in each group was 35.0%, 29.2%, 7.1%, 4.9% and 12.0%, respectively. Compared with the residual liver lobe volume actually measured, that calculated by using the indirect method of substitution of the theoretical liver resection proportion was statistically different in all the other four groups except the left outer lobe group. However, there was no statistical difference between the residual liver lobe volume actually measured and that calculated by the actual liver resection proportion in the 5 groups. In addition, in the preoperative measurement of 5 kinds of basic parameters of rats, the body length has the best correlation with whole liver volume, and the regression equation is \begin{document}$\hat Y = - 27.667 + 0.899X$\end{document}.ConclusionsThe liver volume calculated by indirect method using the actual liver resection proportion, compared with the theoretical liver resection proportion, is more accurate. Compared with the body weight, the body length has the better correlation with whole liver volume.
