Effect of previous intestinal resection on postoperative anastomotic fistula in Crohn′s disease with intestinal resection and anastomosis / 中华普通外科杂志

Objective:To explore the effect of previous intestinal resection on anastomotic fistula within 30 days after surgery in Crohn′s disease.Methods:The clinical data from 92 Crohn′s disease patients who underwent intestinal resection and anastomosis at the Department of General Surgery in Shanghai Ninth People′s Hospital, Shanghai Jiaotong University School of Medicine from Jan 2016 to Sep 2019. Patients were divided into no previous intestinal resection group ( n=45) and previous intestinal resection group ( n=47). The relationship between previous intestinal resection and postoperative anastomotic leak in Crohn′s disease patients with intestinal resection and anastomosis was analyzed. Results:A total of 11 cases (12% leak rate) underwent postoperative anastomotic leak. There were 2 leaks in patients with no previous history of intestinal resection, while 9 leaks in patients with previous bowel resection (χ 2 =4.722, P=0.03). The OR of the postoperative anastomotic leak in Crohn′s disease patients with previous intestinal resection compared with no previous intestinal resection group was 5.092 (95% CI: 1.035-25.048). Patients with 1 previous resection (24 cases) had a leak rate of 13%, whereas patients with >1 previous resection episodes (23 cases) had a leak rate of 26%. The number of previous resection episodes correlated with an increasing risk for clinical anastomotic leak (correlation coefficien r=0.995). Conclusions:Previous intestinal resection is an independent risk factor for ensuing postoperative anastomotic leak in Crohn′s disease patients with intestinal resection and anastomosis.

Vitamin D Improves Intestinal Barrier Function in Cirrhosis Rats by Upregulating Heme Oxygenase-1 Expression

Intestinal barrier dysfunction always accompanies cirrhosis in patients with advanced liver disease and is an important contributor facilitating bacterial translocation (BT), which has been involved in the pathogenesis of cirrhosis and its complications. Several studies have demonstrated the protective effect of Vitamin D on intestinal barrier function. However, severe cholestasis leads to vitamin D depletion. This study was designed to test whether vitamin D therapy improves intestinal dysfunction in cirrhosis. Rats were subcutaneously injected with 50% sterile CCl₄ (a mixture of pure CCl₄ and olive oil, 0.3 mL/100 g) twice a week for 6 weeks. Next, 1,25(OH)₂D₃(0.5 µg/100 g) and the vehicle were administered simultaneously with CCl₄ to compare the extent of intestinal histologic damage, tight junction protein expression, intestinal barrier function, BT, intestinal proliferation, apoptosis, and enterocyte turnover. Intestinal heme oxygenase-1 (HO-1) expression and oxidative stress were also assessed. We found that vitamin D could maintain intestinal epithelial proliferation and turnover, inhibit intestinal epithelial apoptosis, alleviate structural damage, and prevent BT and intestinal barrier dysfunction. These were achieved partly through restoration of HO-1 and inhibition of oxidative stress. Taken together, our results suggest that vitamin D ameliorated intestinal epithelial turnover and improved the integrity and function of intestinal barrier in CCl₄-induced liver cirrhotic rats. HO-1 signaling activation was involved in these above beneficial effects.

New frontiers in the establishment and application of colonic organoids / 中华胃肠外科杂志

Colonic organoids are three-dimensional organotypic cultures of the colonic stem cells or pluripotent stem cells. Its essence is the culture of colonic stem cells or pluripotent stem cells, and their derived intestinal epithelial cells, intestinal endocrine cells and goblet cells in basement membrane extract with specific growth factors. Colonic organoids are comprised of all major types of colonic epithelial cells and represent the architecture and function remarkably similar to those of the colonic epithelium, faithfully recapitulating the functional colonic epithelium ex vivo. As a superior basic experimental model, colonic organoids are representing advantages over conventional cell models and animal models in many aspects, such as high successful rate, short productive cycle, and high consistency with source tissue. Since first reported in 2011, colonic organoids have soon become an important topic in the field of colonic diseases. It has now been applied in the field of physiology of colonic epithelium, infectious diarrhea, ulcerative colitis, regeneration of intestinal injury, and colon tumors. In this review, we summarize the research advances of establishment and application of colonic organoids.

Coordinated Hospital-Home Fecal Microbiota Transplantation via Percutaneous Endoscopic Cecostomy for Recurrent Steroid-Dependent Ulcerative Colitis

Since its introduction as an alternative intestinal microbiota alteration approach, fecal microbiota transplantation (FMT) has been increasingly used as a treatment of choice for patients with ulcerative colitis (UC), but no reports exist regarding FMT via percutaneous endoscopic cecostomy (PEC). This report describes the case of a 24-year-old man with a 7-year history of recurrent, steroid-dependent UC. He received FMT via PEC once per day for 1 month in the hospital. After the remission of gastrointestinal symptoms, he was discharged from the hospital and continued FMT via PEC twice per week for 3 months at home. The frequency of stools decreased, and the characteristics of stools improved soon thereafter. Enteral nutrition was regained after 1 week, and an oral diet was begun 1 month later. Two months after the FMT end point, the patient resumed a normal diet, with formed soft stools once per day. The follow-up colonoscopy showed normal mucus membranes; then, the PEC set was removed. On the subsequent 12 months follow-up, the patient resumed orthobiosis without any gastrointestinal discomfort and returned to work. This case emphasizes that FMT via PEC can not only induce remission but also shorten the duration of hospitalization and reduce the medical costs; therefore, this approach should be considered an alternative option for patients with UC.

Acellular dermal matrix prevents intra-abdominal hypertension for abdominal wall closure following small bowel transplantation: A case report / 中华器官移植杂志

Objective To investigate the effect of acellular dermal matrix (ADM) for abdominal closure to prevent abdominal high pressure after intestinal transplantation.Method ADM was used for abdominal closure following intestinal transplantation in a 17-year-old man with ultra-short bowel syndrome.Two ADMs with 12 cm 20 cm were reconstituted intraoperatively with warm sterile normal saline.After flattened under peritoneum,the ADM was pruned and then sewn to the muscular layer of abdominal wall by interrupted transfixing suture with absorbable suture.A negative pressure drainage tube was placed over an area of native fascia in the subcutaneous space.Skin and soft tissues were closed by interrupted suture.Result The intra-abdominal pressure was not higher than 7 cmH2O 90 h post-operation.The ventilator has been withdrawn 18 h after operation.Enternal nutrition was given from postoperative day 6.He required surgical exploration for abdominal abscess on the postoperative day 19.The ADM closely adhered to the abdominal wall and no abscess in abdomen was related to ADM.Conclusion ADM can be safely used for abdominal closure and effectively prevent intraabdominal high pressure in this intestinal transplantation.No infection or graft loss occurred in the early postoperative period.More observations are needed to study the long-term results and complications in the future.

Objective An ideal small bowel transplantation model is the prerequisite and guarantee of small bowel transplan-tation-related researches.The aim of this study is to establish a pig model of orthotopic segmental small bowel transplantation by modifi-cation of blood vessel reconstruction and surgical techniques. Methods Twenty healthy pigs were equally assigned as donors and re-cipients.The superior mesenteric vessels were freed and the distal ileum harvested as grafts.After irrigation and preservation, the small bowel was transplanted by end-to-end anastomosis of the superior mesenteric arteries and veins, and then the small bowel was re-constructed simultaneously to restore intestinal continuity, with the proximal part of the graft brought out as a stoma for the purpose of graft monitoring. Results Transplantation was successfully performed in 9 of the 10 cases, with a success rate of 90%.The donor operations averaged 100 min, recipient operations 172 min, warm ischemia 1.3 min, cold ischemia 96 min, and vascular anastomosis 27.6 min.No postoperative anastomosis fistula occurred in any of the cases. Conclusion The pig model of orthotopic segmental small bowel transplantation is ideal for small bowel transplantation-related researches.

Analysis of anorectal function in cervical cancer patients with chronic pelvic radiation disease / 医学研究生学报

[Abstract ] Objective Pelvic radiation disease(PRD) is multiple injuries in more than one organ resulted by pelvic radio-therapy.Patients have the symptoms of frequent feces and fecal incontinence after the resection of small bowel lesion .Sugeries on PRD patients were mainly distal ileum and ilieocecal valve resections , while the most susceptible part of pelvic radiation injury is rectum . However , little research has been done concerning PRD patients′anorectal functions .This study was mainly to evaluate the anorectal function of cervical cancer patients with PRD in order to provide evidence for the therapy and prognosis of PRD . Methods Cervical cancer patients with PRD in need of small bowel resection who hospitalized in our department from January 2014 to January 2015 were collected as patient group , while people from outpatient physical exam group were selected as control group according to the exclusion criteria of hypertension , diabetes, constipation and unrelaxed pelvic floor syndrome .PDR group and control group were matched according to age.All subjects underwent colonoscopy and anorectal manometry .Rectal radiation injury was estimated on the basis of colonoscopy results.Anorectal manometry results of PRD group and control group were analysised statistically . Results PRD group and control group both included 20 women without stenosis or obstruction in rectum .Significant difference was found between PRD group and con-trol group in anal resting pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.05), anal maximum squeezing pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.01), anal distension pressure (23.30 ±12.49 mmHg vs 39.10 ±9.99 mmHg, P<0.01), rectal defecation pressure(22.85 ±16,69 mmHg vs 50.90 ±9.14 mmHg, P<0.01) and maximum tolerated rectal volume (112.85 ±51.34 mL vs 173.50 ±48.15 mL, P<0.01).There was no significant difference between the two groups as to the lenghth of functional sphincters(P=0.313),rectum initial threshold(P=0.416) and rectal defecation threshold(P=0.161). Conclusion Ionization radiation that injures PRD patients′internal anal sphincters and external anal sphincters also reduces maximum tolerated rec -tal volumes preoperatively .It′s necessary to assess the muscles and nerve functions of anorectum before intestinal surgery in order to make a proper operation plan which will improve PRD patients′life quality.

Radai tion pelvicopathy:a comprehensive and interdiscipli-nary approach / 医学研究生学报

Radiotherapy is frequently employed as part of the multimodal treatment of cancers.Despite recent advances in ir-radiation techniques, radiation-induced side effects are more common.Radiation enteritis is a term traditionally used to define injury to the small intestine resulting from radiotherapy.The radiotherapy could induce damage of pelvic normal tissue.The most patients with radiation enteritits may also have co-existing radiation-induced damage of pelvic other tissue or organ.The radiation enteritis was man-aged, however, the therapy of pelvic damaged tissue or organ were ignored.Therefore, in 2015, we proposed the concept of radiation pelvicopathy which is most accurate description of the disease process and pathological characteristics.The purpose is to emphasize the interdisciplinary approach of pelvic radiation damage.

Establishment of a porcine model of controlled donors of cardiac death with extracorporeal support / 医学研究生学报

Objective To investigat the changes of hemodynamics and arterial blood gas during the establishment of ECMO model and provide an ideal platform for the study of the mechanism of DCD protection using ECMO, a porcine model of controlled donors of cardiac death (CDCD) with extracorporeal support was established in the paper. Methods Eight domestic crossbred pigs were anes-thetized, atracurium (1mg/kg) and heparin (150~200 U/kg) was administered and the ventilator was discontinued while the animal was under deep anesthesia to kill the animal.Meanwhile, blood was drained from the left jugular vein catheter into the ECMO circuit and re-turned into the left femoral artery to establish the porcine model of CDCD with extracorporeal support . The average blood press and arterial blood gas were ministered at normal, cardiac arrest and ECMO supporting 1 h, 3 h and 5 h. Results The model of CDCD with extra-corporeal support was established successfully.Two animals restored the beating of the heart and the high doses of potassium chloride were given untill cardiac arrest during extracorporeal support.Blood gases throughout the apneic time showed a severe hypoxemia and acidosis, pH and PaO2 reduced to 7.09 ±0.24 and 5.3 ±0.93mmHg respective-ly, which can be improved during extracorporeal support.MAP and PaO2 were maintained over 300mmHg and 65mmHg respectively. Conclusion A new porcine model of controlled donors of cardiacdeath with extracorporeal support has been successfully established and showed to be feasible for related pathophysiological research work.

Feasibility of laparoscopic surgery for chronic adhesive small bowel obstruction / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To determine the feasibility and possible superiority of laparoscopic surgery for chronic adhesive small bowel obstruction(CASBO).</p><p><b>METHODS</b>Clinical data of 36 CASBO patients who underwent laparoscopic surgery in Jinling Hospital from March 2011 to August 2014 were retrospectively reviewed. In addition, 36 cases, matched by age, gender, previous abdominal surgery history, body mass index(BMI) and abdominal adhesion grade, who underwent open surgery from April 2007 to February 2011 were used as controls. General information, operative findings and short-term outcomes were compared between two groups.</p><p><b>RESULTS</b>There were no statistically significant differences in baseline data between the two groups (all P>0.05). Among 36 cases in laparoscopic surgery group, 17 underwent complete laparoscopic surgery, 10 underwent laparoscopic assisted surgery and 9 were converted to open surgery, respectively. The conversion rate was 25%(9/36). Reason of laparoscopic assisted surgery in 3 cases was uncertainty of small bowel injury, in 5 cases was further dissection of intra-loop adhesion and in 2 cases was intestinal resection. Reasons for conversion were small bowel injury in 3 cases and severe adbesion at the abdominal wall in 6 cases. There were no differences between two groups in terms of adhesion score, intra-operative blood loss, operation time, need for small bowel resection, total hospital charge and intra- or post-operational complications. As compared to open surgery, laparoscopic surgery significantly shortened the incision length [median 2 (0 to 10) cm vs. 12(7 to 16) cm, P=0.000], and hospital stay [median 5 (2 to 28) days vs. 7 (4 to 26) days, P=0.001], and improved postoperative recovery of bowel movement [median 2(1 to 20) days vs. 3 (2 to 10) days, P=0.001].</p><p><b>CONCLUSION</b>Laparoscopic surgery can improve postoperative recovery of CASBO with similar morbidity as open surgery.</p>

Advances in diagnosis and treatment of intestinal Behcet's disease / 中华胃肠外科杂志

Behcet's disease (BD) affects gastrointestinal tract is defined as intestinal BD. The diagnosis and therapeutic efficacy of intestinal BD are still lack of specific diagnostic method and effective treatment. Intestinal BD is diagnosed according to established criteria based on colonoscopic features and biopsy. To date, 5-aminosalicylic acid and systemic corticosteroids are established as the first-line therapy, while immunosuppressants and infliximab are used as second-line therapy for patients with glucocorticoid resistant. In the process of therapy, we need to carefully evaluate the patient's condition and be cautious about surgical treatment. Surgical intervention should only be considered in patients with serious complications. In this review, we summarize the recent advances in diagnosis, disease activity index and treatment of intestinal BD, and provide the theoretic proofs to clinical application.
