ObjectiveTo evaluate the efficacy of XiaochengqiMixture (XM) on promoting healing of colonic stoma. MethodsForty Wistar rats were divided into two groups randomly after colonectomy: experimental group (n=20) and control group (n=20). In early postoperatively stage rats were given gastric administration of XM in the experimental group and pure water in the control group. On day 3, 7, and 14 after establishment of animal models, laparotomy was performed in two groups of rats, respectively. Anastomotic stoma and surrounding tissues were harvested to detect the context of hydroxyproline and collagen fiber proportion by Masson dying. ResultsOn day 3 after establishment of animal models, hyperplastic collagen with small fiber was observed while no fasciculus was found. Hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.05). On day 7 after operation, many fasciculuses were found in two groups of rats, hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.01). On day 14 after operation, fasciculuses became bigger and more regular in arrangement, but there was no significant difference between the two groups (Pgt;0.05). ConclusionXM is capable of promoting healing of colonic stoma and might prevent the occurrence of anastomotic fistula.
ObjectiveTo investigate the effects of single anastomosis sleeve ileal (SASI) bypass on weight loss, metabolic improvements, and postoperative safety in patients with obesity and its metabolic comorbidities (such as type 2 diabetes and hyperlipidemia). MethodsA retrospective analysis was conducted. The clinical data of patients with obesity [body mass index (BMI) ≥32.5 kg/m2 or BMI ≥27.5 kg/m2 with metabolic diseases] who underwent SASI bypass in the Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2023 to December 2023. Weight loss outcomes, including the percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), and percentage of excess BMI loss (%EBMIL), were recorded at 6 and 12 months postoperatively. Metabolic disease remission and complications at 12 months postoperatively were also documented. ResultsA total of 82 patients were included in the study. At 12 months postoperatively, the reductions in %TWL, %EWL, and %EBMIL were significantly greater than those observed at 6 months postoperatively [%TWL: (27.1±4.6)% vs. (23.6±3.8)%, t=2.379, P=0.026; %EWL: (72.1±5.8)% vs. (56.6±7.3)%, t=2.593, P<0.001; %EBMIL: (71.6±6.7)% vs. (58.3±4.9)%, t=2.607, P<0.001], remission was observed in 40 out of 48 patients (83.3%) with comorbid hypertension, 49 out of 51 patients (96.1%) with comorbid type 2 diabetes mellitus, and all patients with comorbid hyperlipidemia (33 cases) and obstructive sleep apnea syndrome (29 cases) achieved complete remission. Within 12 months after SASI bypass, 3 patients (3.7%) experienced melena, 2 patients (2.4%) developed incomplete intestinal obstruction, and 10 patients (12.1%) showed malnutrition. ConclusionThe findings of this study indicate that SASI bypass demonstrates significant weight loss and metabolic improvement effects in patients with obesity and metabolic diseases, with a controllable safety profile.
Objective To analyze the growth of anastomotic stoma of aortic(AO) and pulmonary artery (PA) after arteries switch operation(ASO) so as to assess the longterm efficacy of ASO . Methods The data of 331 patients who had undergone ASO in Shanghai Children’s Medical Center of Jiaotong University from December 1999 to December 2007 was analysed retrospectively. One hundred eleven patients had complete transposition of great arteries complicated with intact ventricular septum(TGA/IVS), 123 had complete transposition of great arteries complicated with ventricular septal defect(TGA/VSD), 73 had TaussigBing complicated with ventricular septal defect and pulmonary hypertension, and 24 underwent StageSwitch. Of the 331 patients 228 were followedup, and the followup time was 20.4±18.6 months. There were 752 ultrasonic cardiograph reports, 3.3per patient on average. The growth of anastomosis was analysed according to the diameters of AO and PA. Results The AO and PA anastomosis diameters of TGA/IVS patients（before discharge 0.74±0.17 cm and 0.65±0.13 cm, latest followup 1.09±0.31cm and 0.84±0.21 cm）, TGA/VSD patients (before discharge 0.76±0.20 cm and 0.63±0.14 cm, latest followup 1.09±0.24 cm and 0.82±0.22 cm) and TaussigBing patients（before discharge 0.84±0.25 cm and 0.74±0.20 cm, latest followup 1.05±0.30 cm and 0.85±0.24 cm） growed significantly（Plt;0.05）. The AO anastomotic stoma diameters of patients who had underwent StageSwtich (before discharge 0.93±0.19 cm, latest followup 1.19±0.29 cm) growed significantly（Plt;0.05）. The PA anastomotic stoma diameter growed（before discharge 0.90±0.27 cm, latest followup 1.00±0.32 cm）, but had no statistical significance (P＞0.05). Till November 2008, Six patients needed reoperation because of the right or left ventricle outflow tract obstruction. After reoperation, 3 had no residual obstruction, 3 had residual obstruction. Conclusion After the section and suture of ASO, aortic and pulmonary artery can grow with age, but sometimes stenosis happens to some patients. During the followingup, some patients need reoperation.
In this study, the effect of neostigmine on the healing of colonic anastomoses has been investigated following onestage resection and anastomosis for complete leftsided colomic obstruction.It was found that neostingmine promoted colonic anastomotic healing either experimentally or clinically. Further, the authors discuss the pathogenesis of anastomotic leakage but suggest that neostigmine should be used in the first 5 hours after operation.
ObjectiveTo summarize the experience in the treatment of anastomotic leakage after laparoscopic D2 radical gastrectomy.MethodThe clinicopathologic data of 11 patients with anastomotic leakage after the laparoscopic D2 radical gastrectomy in the Nanchong Central Hospital from May 2016 to January 2018 were analyzed retrospectively.ResultsAmong the 11 patients with anastomotic leakage, 3 were grade Ⅱ leakages and 8 were grade Ⅲa leakages. There were no symptoms in the 3 cases of anastomotic leakage, which were confirmed only by the gastrointestinal radiography and were healed after 7 d of conservative treatment. Among the 8 patients with the clinical symptoms, 5 cases were treated by the endoscopic drainage and negative pressure suction for 60–90 d, 3 cases were treated by the endoscopic covered stent, 2 cases were cured after 30–60 d, and 1 case died of massive bleeding after 45 d.ConclusionsDue to differences of location, time, limitation, and size of anastomotic leakage after laparoscopic D2 radical gastrectomy, individualized treatment should be performed according to specific situation of patients in local treatment. Endoluminal covered stent has certain clinical application value.
ObjectiveTo study feasibility of sheath technique with seromuscular sleeve of pedicled colon in preventing anastomotic leakage following laparoscopic anterior resection of rectal cancer.MethodsThe clinical data of patients who underwent laparoscopic anterior resection of rectal cancer in our hospital from January 2017 to March 2020 were retrospectively collected. According to different surgical methods, they were divided into two groups: pedicled seromuscular sleeve sheath group (referred to as sleeve sheath operation group) and traditional operation group. The intraoperative and postoperative statuses were compared between these two groups.ResultsIn this study, 87 patients with rectal cancer were included, 37 in the sleeve sheath operation group and 50 in the traditional operation group. There were no significant differences in the baseline data such as the gender, age, body mass index (BMI), complicating disease, distance from lower tumor margin to anal verge, histological classification, neoadjuvant radio- chemotherapy, and TNM stage between the two groups (P>0.05). There were no significant differences in the volumes of intraoperative blood loss, the number of lymph node dissection, the first postoperative anal exhaust time and the hospitalization expense between the two groups (P>0.05). Compared with the traditional operation group, the operative time of the sleeve sheath operation group was longer (P<0.05), the postoperative hospitalization time of the sleeve sheath operation group was shorter (P<0.05). The incidence of postoperative anastomotic leakage in the sleeve sheath operation group and the traditional group were 0.0% (0/37) and 12.0% (6/50), respectively, and the difference was statistically significant (P<0.05). There were no significant differences in the anastomotic stenosis, the lymphatic fistula and the incision infection between the two groups (P>0.05). All patients were followed-up for 6 to 36 months, with a median time of 21 months. No recurrence or death occurred.ConclusionThe sheath technique with seromuscular sleeve of pedicled colon can increase the anti tension ability of anastomotic stoma and reduce the incidence of anastomotic leakage, which is a safe and effective surgical method.
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.
