ObjectiveTo summarize a patient diagnosed as Bismuth type Ⅲa hilar cholangiocarcinoma who unerwent the curative surgery combined with partial portal vein resection and reconstruction+hilar bile duct formation+Roux-en-Y choledochojejunostomy, meanwhile we reviewed the current status of surgical treatment of hilar cholangiocarcinoma at home and abroad.MethodsTo retrospectively summarized and analyzed the clinical data of one case of Bismuth type Ⅲa hilar cholangiocarcinoma. The preoperative total bilirubin of this patient was 346.8 μmol/L, and this patient underwent the curative surgery combined with partial portal vein resection and reconstruction+hilar bile duct formation+Roux-en-Y choledochojejunostomy after reducing jaundice by percutaneous transhepatic biliary drainage (PTBD). Then we retrieved domestic and foreign related literatures.ResultsOperative time of this patient was about 290 min and intraoperative bleeding was about 350 mL. No intraoperative blood transfusion occurred. The results of pathological examination showed middle-differentiatied adenocarcinoma of hilar bile duct with negative tumor margins and no regional lymph node metastasis (0/14). The postoperative recovery was uneventful with hospital stay time of 9 days and without any complication. The patient had been followed-up in the outpatient department for 3 years,and was generally in good condition. The evidence of recurrence or metastasis wasn’t found.ConclusionsPre-operative biliary drainage can improve the safety of operation and reduce the incidence of postoperative complications, extend liver resection for the patient with Bismuth type Ⅲa hilar cholangiocarcinoma, which can improve R0 resection rate and extend postoperative survival.
Objective To study the application of ultracision harmonic scalpel in laparoscopic radical gastrectomy. Methods Ten patients with gastric cancer were given laparoscopic-assisted radical gastrectomy by using ultracision harmonic scalpel. Results All operations were successfully performed with ultracision harmonic scalpel, and none of which converted into open surgery. The operation time was 300-492 min, mean (385±64) min. The blood loss was 100-500 ml, mean (401±70) ml. The number of harvested lymph nodes was 21-43, mean 31±6. The time for gastrointestinal function recovery was 3-6 d, mean (4.2±1.0) d. The time of patients’ taking out-of-bed activity was 3-７ d, mean (4.5±1.3) d. The time of taking liquid food was 4-６ d, mean (5.0±0.9) d. No case had relapse or metastasis after 4-20 months (mean 12.6 months) of follow-up. Conclusions Laparoscopic radical gastrectomy by using ultracision harmonic scalpel is safe and feasible. Ultracision harmonic scalpel has the advantage of minimal invasion, less bleeding and shorter operation time, which is a very important equipment and useful for laparoscopic gastrointestinal surgery.
ObjectiveTo analyze the safety and feasibility of laparoscopic intersphincteric resection with stapled colo-anal anastomosis under direct vision for low rectal cancer. MethodsFrom January 2001 to March 2012, 138 patients were underwent intersphincteric resection for low rectal cancer, 45 cases of whom were received laparoscopic surgery and stapled colo-anal anastomosis (SCAA group), and the other 93 cases (55 open and 38 laparoscopic) of whom were received hand-sewn colo-anal anastomosis (HCAA group). The morbidity comparison only involed the data of relevant to the anastomosis. The anus functional outcomes, including those from the Saito function questionnaire and Wexner score, were compared and only involved the data of relevant to the laparoscope. Results①The anastomotic complications rates were similar for the fistula, bleeding, and rectal mucosal prolapse (P > 0.05); the rate of anastomosis leakage and the degree of anastomotic stricture in the SCAA group were significantly lower (or milder) than those in the HCAA group (P=0.001 and P=0.022, respectively).②As for the functional results, the incidence of dyschesia in the SCAA group was significantly lower than that in the HCAA group (P=0.016), and the other 7 items of Saito function questionnaire and Wexner score were similar between these two groups (P > 0.05). ConclusionsCompared with traditional intersphincteric resection for low rectal cancer, laparoscopic surgery with stapled colo-anal anastomosis could reduce the morbidity and the anus function is non-inferior to the former.
ObjectiveTo evaluate the efficacy of robotic intersphincteric resection (ISR) for rectal cancer.MethodsA literature search was performed using the China biomedical literature database, Chinese CNKI, Wanfang, PubMed, Embase, and the Cochrane library. The retrieval time was from the establishment of databases to April 1, 2019. Related interest indicators were brought into meta-analysis by Review Manager 5.2 software.ResultsA total of 510 patients were included in 5 studies, including 273 patients in the robot group and 237 patients in the laparoscopic group. As compared to the laparoscopic group, the robot group had significantly longer operative time [MD=43.27, 95%CI (16.48, 70.07), P=0.002], less blood loss [MD=–19.98.27, 95%CI (–33.14, –6.81), P=0.003], lower conversion rate [MD=0.20, 95%CI (0.04, –0.95), P=0.04], less lymph node harvest [MD=–1.71, 95%CI (–3.21, –0.21), P=0.03] and shorter hospital stay [MD=–1.61, 95%CI (–2.26, –0.97), P<0.000 01]. However, there were no statistically significant differences in the first flatus [MD=–0.01, 95%CI (–0.48, 0.46), P=0.96], time to diet [MD=–0.20, 95%CI (–0.67, 0.27), P=0.41], incidence of complications [OR=0.76, 95%CI (0.50, 1.14), P=0.18], distal resection margin [MD=0.00, 95%CI (–0.17, 0.17), P=0.98] and positive rate of circumferential resection margin [OR=0.61, 95%CI (0.27, 1.37), P=0.23].ConclusionsRobotic and laparoscopic ISR for rectal cancer shows comparable perioperative outcomes. Compared with laparoscopic ISR, robotic ISR has the advantages of less blood loss, lower conversion rate, and longer operation times. These findings suggest that robotic ISR is a safe and effective technique for treating low rectal cancer.

Objective To explore the operative method and effectiveness of talocalcaneal coal ition.Methods Between July 2008 and October 2010, 10 patients with talocalcaneal coal ition were treated, including 2 cases ofcongenital talocalcaneal coal ition and 8 cases of secondary talocalcaneal coal ition. There were 4 males and 6 females, aged53.5 years on average (range, 16-70 years). Three patients had middle-facet talocalcaneal coal ition and 7 had posterior-facettalocalcaneal coal ition. The preoperative visual analogue score (VAS) was 9.0 ± 0.4. According to American OrthopedicFoot and Ankle Society (AOFAS) hindfoot scale, the score was 42.4 ± 1.4. Two cases compl icated by subtalar degeneration.Resection of the bone bar and fat packing were performed in 8 cases of simple talocalcaneal coal ition, and resection and subtalararthrodesis in 2 cases of talocalcaneal coal ition combined with subtalar degeneration. Results Primary healing of incisionswas obtained in all patients. Eight patients were followed up 18 months on average (range, 12-36 months). At last follow-up,VAS was 2.0 ± 0.7, showing siginificant difference when compared with preoperative score (t=6.425, P=0.000). AOFAS score was86.9 ± 2.3, showing significant difference when compared with preoperative score (t=7.634, P=0.000). The X-ray films showedthat no recurrence of talocalcaneal coal ition was observed in patients underdoing simple removal of bone bar, and bone fusionwas observed in patients undergoing arthrodesis. Conclusion To achieve satisfactory outcomes for talocalcaneal coal ition, areasonable surgical procedure should be chosen according to the specific facet and complication.
ObjectiveTo investigate the cause of stoma recurrence after anterior resection of rectal cancer and discover the methods of prevention and treatment.MethodsA total 91 patients with stoma recurrence after anterior resection of rectal cancer (or Dixon) were analysed retrospectively between 1985 and 1996. Fourtyseven patients experienced reradical resection (Miles), 27 cases palliative resection, and 11 cases only exploration. Thirtytwo cases had been followed up for 5 years and obtained 1，3，5year survival rate for reradical radical resection (Miles). Diagnosis and treatment of stomal recurrence after Dixon were evaluated. ResultsOne, three and fiveyear survival rate of reradical resection (Miles) was 93%，77%，45% respectively.ConclusionTo amplify blindly the adaptation of Dixon is to raise the rate of stoma recurrence. Digital rectal examination and fiberopic colonoscopy (and biopsy) are very essential methods for the diagnosis of stoma recurrence, and we strive to do reradical resection (Miles) for the patients with stoma recurrence after Dixon’s operation.
Hepatic alveolar echinococcosis (HAE) is a severe zoonotic disease caused by Echinococcus multilocularis, primarily affecting the liver. Due to its insidious nature, the patients are often diagnosed at advanced stage, posing significant treatment challenges. We comprehensively examines the progress in surgical techniques for HAE management, focusing on various strategies across different disease stages. For the patients with early-stage HAE, ablation therapy has emerged as an effective treatment option. In the moderate to advanced cases, numerous surgical techniques and innovative approaches have been introduced, including laparoscopic surgery and liver transplantation, with particular emphasis on ex vivo liver resection and autotransplantation. These advancements offer more effective treatment options for the patients with advanced HAE. However, significant challenges persist, notably the preservation of adequate liver function while achieving complete lesion removal. Future research should prioritize the exploration and optimization of existing surgical methods, especially for advanced HAE cases. This includes refining surgical techniques through precise preoperative evaluation and staging, as well as developing novel surgical approaches to enhance safety and efficacy. Furthermore, multicenter and long-term follow-up prospective studies are crucial for validating the effectiveness of new surgical techniques and strategies. Through these concerted efforts, it is anticipated that the survival rates and quality of life for HAE patients will significantly be improved, marking a new era in the management of this complex disease.
ObjectiveTo summarize the experiences of precise liver resection for giant complex hepatic neoplasm. MethodsFifty-two cases of giant complex hepatic neoplasms were resected using precise liver resection techniques from April 2008 to August 2009. Hepatic functional reserve and liver imaging were evaluated before operation. Appropriate surgical approach, halfhepatic blood flow occlusion, new technique of liver resection, and intraoperative ultrasonography were applied during operation. ResultsThe mean operative time, halfhepatic blood occlusion time, blood loss, recovery of alanine aminotransferase, and total bilirubin were 350 min (210－440 min), 43 min (8－57 min), 370 ml (250－1 150 ml), 10 d (7－14 d), and 4.5 d (3－10 d), respectively. Only 6 patients had mild bile leakage. No liver failure and other major complications emerged, and no death happened. ConclusionPrecise liver resection is a safe and effective approach for giant complex hepatic neoplasm.
Mitral valvuloplasty is a more suitable surgical procedure than mitral valve replacement in the case of mitral valve degeneration. Quadrangular resection and artificial chordae plantation, considered to be classical procedures, are widely employed in posterior mitral valve prolapse, and have prominent long-term effects during the follow-up. However, is there any difference in mitral valve reconstruction due to completely different surgical methodology and concepts of the two procedures? Every surgeon has his own ideas and preferences for mitral valvuloplasty, and the choice of surgical procedures mostly depends on experience of surgeons. The article generally reviews variances in intraoperative and long-term clinical outcomes of both rectangular excision and artificial chordae plantation in posterior leaflet valvuloplasty, hoping to provide references for clinical decision.
