OBJECTIVETo analyze the pathohistological changes of the livers and the clinical features of patients with biliary tract complications after their orthotopic liver transplantations.
METHODSFrom Sept 1998 to June 2005 clinical and pathological data of 173 post-liver transplantation patients with biliary tract complications were analyzed.
RESULTSBiliary tract complications occurred within 3-2920 days after the transplantation operations. These complications occurred within 1-30 days, 31-90 days, 91-180 days, 180 days at rates of 49.71%, 17.92%, 4.62%, 27.74% respectively. The complications were of inflammatory nature in 171 cases, (72.25%), and of obstructive nature in 164 cases (27.74%). The main pathological changes were epithelium degeneration of interlobular bile ducts, inflammatory cell infiltration in portal areas, proliferation of interlobular bile ducts, fibrosis in portal areas, cholestasis in small bile ducts and hepatocytes.
CONCLUSIONMany of the biliary tract complications of post-liver transplantation in our cases were of inflammatory nature and they often occurred within 30 days after the surgery. Obstructive nature complications often occurred in 90 days after the surgery and the prognosis of these cases was much poorer. The pathological changes of live tissues shown in liver biopsies are important for prognostic evaluation, differential diagnosis and categorization of biliary tract complications.

3.Comparison of the incidence of postoperative ileus following laparoscopic and open radical resection for colorectal cancer: a meta-analysis.
Chinese Journal of Gastrointestinal Surgery 2012;15(10):1044-1047
OBJECTIVETo compare the incidence of postoperative ileus following laparoscopic and open radical resection for colorectal cancer using meta-analysis.
METHODSThe Cochrane library, Pubmed, Ovid databases were searched as of October 2011. Two reviewers extracted the data and assessed the methodological quality independently. The homogeneity of studies was evaluated and the meta-analysis was conducted by the Cochrane Collaboration RevMan 5.0 software.
RESULTSSeven studies including 3630 cases were analyzed. A total of 1814 patients received laparoscopic surgery, of whom 58 developed postoperative ileus. There were 1816 cases undergoing open surgery, of whom 105 developed early postoperative ileus. The pooled relative risk was 0.55 with a 95% confidence interval of 0.41-0.76. The difference was statistically significant(P<0.01).
CONCLUSIONCompared with open surgery, laparoscopic colorectal resection can reduce the incidence of postoperative ileus.

OBJECTIVE: Although nerve-sparing radical surgery (NSRS) is an emerging technique for reducing surgery-related dysfunctions, its efficacy is controversial in patients with cervical cancer. Thus, we performed a meta-analysis to compare clinical outcomes, and urinary, anorectal, and sexual dysfunctions between conventional radical surgery (CRS) and NSRS. METHODS: After searching PubMed, Embase, and the Cochrane Library, two randomized controlled trials, seven prospective and eleven retrospective cohort studies were included with 2,253 patients from January 2000 to February 2014. We performed crude analyses and then conducted subgroup analyses according to study design, quality of study, surgical approach, radicality, and adjustment for potential confounding factors. RESULTS: Crude analyses showed decreases in blood loss, hospital stay, frequency of intraoperative complications, length of the resected vagina, duration of postoperative catheterization (DPC), urinary frequency, and abnormal sensation in NSRS, whereas there were no significant differences in other clinical parameters and dysfunctions between CRS and NSRS. In subgroup analyses, operative time was longer (standardized difference in means, 0.948; 95% confidence interval [CI], 0.642 to 1.253), while intraoperative complications were less common (odds ratio, 0.147; 95% CI, 0.035 to 0.621) in NSRS. Furthermore, subgroup analyses showed that DPC was shorter, urinary incontinence or frequency, and constipation were less frequent in NSRS without adverse effects on survival and sexual functions. CONCLUSION: NSRS may not affect prognosis and sexual dysfunctions in patients with cervical cancer, whereas it may decrease intraoperative complications, and urinary and anorectal dysfunctions despite long operative time and short length of the resected vagina when compared with CRS.

5.Risk of Chronic Kidney Disease After Nephrectomy for Renal Cell Carcinoma.
Korean Journal of Urology 2014;55(10):636-642
The incidence of low-stage renal cell carcinoma is rising and is observed to demonstrate excellent prognosis following surgical treatment irrespective of method. However, several epidemiologic observational and population-based studies suggest that radical nephrectomy is associated with increased adverse renal outcomes such as chronic kidney disease (CKD) compared with partial nephrectomy. This is suggested in turn to lead to increased mortality via an increase in cardiovascular complications and mortality. Prospective data are scarce, and there are conflicting data as well on whether surgically induced CKD is as debilitating as medically induced CKD. Further research is needed to assess the presence and the extent of the relationship between nephrectomy, CKD, and noncancer mortality.

6.Epidemiological characteristics and inducing factors of gastric stump cancer.
Chinese Journal of Gastrointestinal Surgery 2018;21(5):498-501
Gastric stump cancer was initially defined as a carcinoma of the stomach occurring more than 5 years after surgery for gastric or duodenal benign disease. In recent years, as the number of total gastrectomy for benign disease has gradually decreased and the gastric cancer detection and operation rate have annually increased, residual recurrence of primary gastric cancer more than 10 years after gastric cancer surgery has also been considered as gastric stump cancer. The incidence of gastric stump cancer is increasing annually. The epidemiological characteristics of this form of cancer are also developing, and they show a higher incidence in males compared to females. The incidence has been affected following digestive tract reconstruction, and the risk increases in patients who undergo Billroth II( reconstruction. The interval of onset is related to the benign and malignant condition of primary disease, and the incidence increases after 10 years of early gastric cancer surgery. Lymph node metastasis pattern in gastric stump cancer is different from that in primary gastric cancer as the primary operation may destroy normal lymph flow. Many factors are known to cause gastric stump cancer, mainly duodenal gastric reflux, Helicobacter pylori infection, and gastric mucosal barrier dysfunction; however, the mechanism is not clear. It is expected to reduce the incidence of gastric stump cancer by taking precautionary measures against different inducements, which also has some guiding significance for the treatment and prognosis of gastric cancer.

7.Influence of different sphincter-preserving surgeries on postoperative defecation function.
Chinese Journal of Gastrointestinal Surgery 2022;25(6):482-486
Advances in surgical techniques and treatment concept have allowed more patients with low rectal cancer to preserve sphincter without sacrificing survival benefit. However, postoperative dysfunctions such as fecal incontinence, frequency, urgency, and clustering often occur in patients with low rectal cancer. The main surgical procedures for low rectal cancer include low anterior rectum resection (LAR), intersphincteric resection (ISR), coloanal anastomosis (Parks) and so on. The incidence of major LARS after LAR is up to 84.6%. The postoperative function of ISR is even worse than LAR. Moreover, the greater the extent of resection ISR surgery, the worse the postoperative function. There are few studies on the function of Parks procedure. Current evidence suggests that the short-term function of Parks procedure is inferior to LAR, but function can gradually recovered over time. Colorectal surgeons have attempted to improve postoperative defecation by modifying bowel reconstructions. Current evidence suggests that J pouch or end-to-side anastomosis during LAR does not reduce the incidence of defecation disorders. Pouch reconstruction during ISR cannot reduce the incidence of severe LARS either. In general, the protection of postoperative defecation function in patients with low rectal cancer still has a long way to go.

OBJECTIVETo compare clinically relevant postoperative complications after open, laparoscopic, and robotic gastrectomy for gastric cancer.
METHODSClinical data of patients with gastric cancer who underwent gastrectomy between January 1, 2014 and October 1, 2016 at Chinese People's Liberation Army General Hospital were analyzed retrospectively. All the patients were diagnosed by upper endoscopy and confirmed by biopsy without distant metastasis. They were confirmed with R0 resection by postoperative pathology. Patients with incomplete data were excluded. The complications among open group, laparoscopic group and robotic group were compared. The continuous variables were analyzed by one-way ANOVA, and categorical variables were analyzed by χtest or Fisher exact test.
RESULTSA total of 1 791 patients (1 320 males and 471 females) were included in the study, aged from 17 to 98 (59.0±11.6) years, comprising 922 open, 673 laparoscopic and 196 robotic gastrectomies. There were no significant differences among three groups in baseline data (gender, age, BMI, comorbidity, radiochemotherapy) and some of operative or postoperative data (blood transfusion, number of lymph node dissection, combined organ resection, resection site, N stage, postoperative hospital stay). The blood loss in laparoscopic and robotic groups was significantly lower than that in open group[(185.7±139.6) ml and (194.0±187.6) ml vs. (348.2±408.5) ml, F=59.924, P=0.000]. The postoperative complication occurred in 197 of 1 791(11.0%) patients. The Clavien-Dindo II(, III(a, III(b, IIII(a, and IIIII( complications were 5.5%, 4.0%, 1.2%, 0.1%, and 0.2% respectively. The anastomotic leakage (2.4%), intestinal obstruction(1.3%) and pulmonary infection(1.2%) were the three most common complications, followed by wound infection(0.8%), cardiovascular disease(0.7%), anastomotic bleeding (0.7%), delayed gastric emptying (0.6%), duodenal stump fistula(0.5%), intraperitoneal hemorrhage (0.5%), pancreatic fistula (0.3%), intra-abdominal infection(0.2%), chylous leakage (0.1%) and other complications(1.7%). There were no significant differences among three groups as the complication rates of open, laparoscopic and robotic gastrectomy were 10.6%(98/922), 10.8%(73/673) and 13.3%(26/196) respectively (χ=1.173, P=0.566). But anastomotic leakage occurred more common after laparoscopic and robotic gastrectomy compared to open gastrectomy [3.1%(21/673) and 5.1%(10/196) vs. 1.3%(12/922), χ=12.345, P=0.002]. The rate of cardiocerebral vascular diseases was higher in open group[1.3%(12/922) vs. 0.1%(1/673) and 0, χ=8.786, P=0.012]. And the rate of anastomotic bleeding was higher in robotic group [2.0%(4/196) vs. open 0.4%(4/922) and laparoscopic 0.6%(4/673), χ=6.365, P=0.041]. In view of Clavien-Dindo classification, III(a complications occurred more common in laparoscopic group [5.5%(37/673) vs. open 3.3%(30/922) and robotic 2.6%(5/196), χ=6.308, P=0.043] and III(b complications occurred more common in robotic group [3.1%(6/196) vs. open 1.1%(10/922) and laparoscopic 0.7%(5/673), χ=7.167, P=0.028].
CONCLUSIONSMorbidities of postoperative complications are comparable among open, laparoscopic and robotic gastrectomy for gastric cancer. However, in consideration of the high difficulty of anastomosis, the minimally invasive surgery should be performed by more experienced surgeons.

BACKGROUND:
Through the comparative analysis of the acute and chronic pain postoperative between the single port and triple port video-assisted thoracic surgery to seek the better method which can reduce the incidence of acute and chronic pain in patients with lung cancer.
METHODS:
Data of 232 patients who underwent single port -VATS (n=131) or triple port VATS (n=101) for non-small cell lung cancer (NSCLC) on January 1, 2016 to June 30, 2017 in our hospital were analyzed. The clinical and operative data were assessed, numeric rating scale (NRS) was used to evaluate the mean pain score on the 1th, 2th, 3th, 7th, 14th days, 3th months and 6th months postoperative.
RESULTS:
Both groups were similar in clinical characteristics, there were no perioperative death in two groups. In the 1th, 2th, 7th, 14th days and 3th, 6th months postoperative, the NRS score of the single port group was superior, and the difference was significant compared with the triple port (P<0.05). There was no statistically significant difference between the two groups in operative time, blood loss, postoperative hospitalization time, duration of chest tube, the NRS scores in the 3 d (P>0.05). Univariate and multivariate analysis of the occurrence on the chronic pain showed that the operation time, surgical procedure and the 14th NRS score were risk factors for chronic pain (P<0.05).
CONCLUSIONS
The single port thoracoscopic surgery has an advantage in the incidence of acute and chronic pain in patients with non-small cell lung cancer. Shorter operative time can reduce the occurrence of chronic pain. The 14th day NRS score is a risk factor for chronic pain postoperative.

10.Surgical treatment and prognosis of left obstructive colorectal carcinoma.
Journal of Central South University(Medical Sciences) 2009;34(4):335-339
OBJECTIVE:
To investigate the effect of surgical management and prognosis of left obstructive colorectal carcinoma.
METHODS:
Clinical data of 109 patients with acute left obstructive colorectal carcinoma treated by emergent operation in Xiangya Hospital from October 2000 to February 2008 were retrospectively analyzed.
RESULTS:
All the 109 patients received operation. Of them, 66 patients received one stage tumor resection and intestinal anastomosis. Postoperative complication rate was 26.6%(29/109) and mortality rate was 0.9%(1/109). The postoperative 1-, 3-, and 5-year survival rates were 94.4%, 73.3%, and 43.2%, respectively. The 1-,3-,and 5-year survival rates of patients receiving curative resection were 100.0%,93.6%, and 66.7%, respectively. With univariate analysis, radical resection, Dukes stage, tumor differentiation, and chemotherapy were found to be significant factors associating with the overall survival. With multivariate analysis, radical resection independently affected the overall survival.
CONCLUSION
One stage radical resection and anastomosis are feasible for left obstructive colorectal carcinoma. Appropriate choice of the operative procedure, skillful operative techniques, and prudential peri-operative treatment can enhance the curative effect and patients quality of life.
