Objective To discuss the pathogeny， treatment and prophylactic measures of postcholecystectomy syndrome (PCS). Methods The clinical data of 150 patients with laparoscopic PCS in our department from October 2000 to March 2009 were analyzed. Results Etiological factors were found in 131 patients: one hundred and twelve cases were due to the reasons of biliary system, including bile duct residual stones after cystic resection， the injury bile duct stenosis， a long residual cystic canal， nipple benign stricture, bile duct tumor etc; Nineteen examples were due to other reasons, including gallbladder stone merger reflux gastritis, gastroduodenal ulcer， diverticulum beside duodenal nipple, and so on, which resulted in the symptoms un-release after cystic resection. Nineteen cases were not found organic lesion. In ones whose etiological factors were definite, 117 cases were treated with different surgeries according to different etiological factors; another 33 cases were treated with conservative treatment. Total 145 cases were followed up, and 139 cases in them were cured or relieved at different degrees. Conclusion Careful preoperative examination, normalized operation avoiding damaging bile duct and leaving behind bile duct stones can effectively prevent laparoscopic PCS.
Objective To explore application value of three-dimensional (3D) laparoscopic visualization during bariatric surgery. Methods From January 2015 to May 2017, 64 patients underwent laparoscopic bariatric surgery in our department were included. Among these cases, 19 patients underwent 3D laparoscopic sleeve gastrectomy, and 21 patients underwent two-dimensional (2D) laparoscopic sleeve gastrectomy. Thirteen patients underwent 3D laparoscopic Roux-en-Y gastric bypass, and 11 patients underwent 2D laparoscopic Roux-en-Y gastric bypass. The total operative time, the digestive tract reconstruction time, the intraoperative blood loss, the postoperative hospitalization stay, and the operative complications were analyzed statistically. Results The laparoscopic bariatric surgery were performed successfully in all the 64 patients, no case was converted to the laparotomy, and no 3D laparoscopy was converted to the 2D laparoscopy. The suture time of the gastric incisal margin was shorter and the intraoperative blood loss was less with the 3D laparoscopic sleeve gastrectomy as compared with the 2D laparoscopic sleeve gastrectomy (P<0.05), but the total operative time and the postoperative hospitalization stay had no significant differences and none of postoperative complications happened between these two modes (P>0.05). The total operative time, the time to make gastric pouch, the time of the gastro-jejunal anastomosis or jejunum-jejunum anastomosis, and the intraoperative blood loss with the 3D laparoscopic Roux-en-Y gastric bypass were significantly less than those with the 2D laparoscopic Roux-en-Y gastric bypass (P<0.05), but the postoperative hospitalization stay had no significant difference between these two modes (P>0.05). Conclusion Pre-liminary results of limited cases in this study shows that 3D laparoscope could provide 3D stereoscopic visualization, which facilitateto clearly identify anatomical structures, and be helpful to complex operations, and then might reduce operating time, both physicians and patients could benefit from it.
Objective To analyse the clinico-pathological characteristics of young patients with colorectal cancer. Methods From January 1980 to January 2000, among 1 030 patients with colorectal cancer admitted for surgical treatment, 143 (13.9%) patients were ＜35 years of age. The clinicopathological data of these young patients were reviewed and compared with those of patients in the other age groups. Results In this series of young patients, males were predominat. Most of them were with poorly differentiated (37.8%) and muco-cellular (29.6%) adenocarcinoma. The mast common gross morphology was infiltrating type (56.6%) and colloid carcinoma type (31.5%). The majority of patients (89.5%) were in Dukes stage B and stage C. Conclusion The prognosis of young patients with colorectal cancer surgically treated is worse, due to the fact that most of them are in late stage and their cancers are worse in differentiation. To increase the awareness of cancer in the young is important for early diagnosis and treatment and better prognosis.
Objective To approach the clinical effect，feasibility， and advantages and disadvantages of laparoscopic liver resection for liver tumor. Methods The clinical data of 32 patients with liver tumor underwent laparoscopic liver resection from January 2009 to August 2011 in this hospital were analyzed retrospectively. Results The laparoscopic liver resection of 32 patients with liver tumor were performed successfully，including 23 cases of primary liver cancer，5 cases of metastatic liver，3 cases of liver hemangioma，1 case of focal liver nodular hyperplasia. Laparoscopic liver resection included left lateral lobectomy （Ⅱ＋Ⅲ segments） in 17 cases，left internal lobectomy （Ⅳ segment） in 2 cases （left lateral lobe was already removed），left hemihepatectomy （Ⅱ＋Ⅲ＋Ⅳ segments） in 8 cases，Ⅴsegmentectomy in 1 case，and Ⅵ segmentectomy in 1 case，and Ⅲ，Ⅳ，and Ⅴ segments hemihepatectomy in 3 cases. The average operation time of hepatectomy was 75-285 min with an average 215 min. Intraoperative bleeding was 115-760 ml with an average 365 ml. No complications such as bile leakage，hemorrhage，air embolism, and so on happened. The time of gastrointestinal function recovery was 1-3 d. The hospital stay was 5-11 d with an average 6 d. Thirty-one cases were followed-up，the follow-up time was 6-32 months with an average 18 months，except one case was died of tumor recurrence and metastasis in one year after operation，the rest were alive，no tumor recurrence and metastasis happened. Conclusions Laparoscopic liver resection for liver tumor has a small wound，less suffering，quick recovery，which is safe and feasible. The clinical effect is good．
ObjectiveTo systematically review the efficacy of patient decision aids (PDA) in the selection of treatment modalities for end-stage renal diseases. MethodsThe PubMed, Web of Science, Embase, Cochrane Library, CBM, CNKI and VIP databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to March 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Quantitative and qualitative analysis was then performed. ResultsA total of 8 RCTs involving 1 544 patients were included. The systematic review results showed that PDA could improve patient knowledge, reduce patient decision-making conflict, and change patient decision-making discussion rate. ConclusionCurrent evidence shows that patients with end-stage renal diseases can benefit from PDA to improve their decision-making knowledge and reduce conflicts in their decisions, but its impact on the decision-making outcome index is limited.
Objective To discussion the surgical approach of laparoscopic resection of left hepatic lobe. Methods The clinical data of 86 patients with Intr- and extra-hepatic bile duct stones and liver hemangioma were analyzed retros-pectivly. Eighty-six patients underwent laparoscopic hepatectomy. Forty-nine cases underwent the left hepatic lobe resectionby the left longitudinal groove （left longitudinal groove group）， 37 cases underwent the left hepatic lobe resection by the first hepatic portal （first porta hepatis group）. The operative time， intraoperative bleeding volume， postoperative hospital stay， and postoperative complications of two kinds of operation were compared. Results The operative time and intraoperative bleeding volume of left longitudinal groove group were shorter or less than those of the first porta hepatis group 〔（142±123）min vs. （208±58）min，P＜0.05； （320.5±38.3）mL vs. （450.9±39.1）mL，P＜0.05〕. There were no statistically significant difference between the 2 groups in complication and hospitalization after operation （P＞0.05）. Conclusion The left hepatic lobe resection by the left longitudinal groove is more safe and fast.
