Source of portal vein tumor thrombosis and advances in its diagnosis and treatment / 临床肝胆病杂志

Portal vein tumor thrombosis is one of the important factors that affect the treatment and prognosis of patients with malignancies. The early diagnosis and treatment of portal vein tumor thrombosis is of great significance to improve the prognosis of patients. However, at present, there is no standard and unified guideline for the diagnosis and treatment of portal vein tumor thrombosis. This article reviews the source as well as the advances in diagnosis and treatment of portal vein tumor thrombosis.

A prospective randomized controlled trial of laparoscopic repair versus open repair for perforated peptic ulcers / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To compared the clinical efficacy of laparoscopic repair (LR) versus open repair (OR) for perforated peptic ulcers.</p><p><b>METHODS</b>From January 2010 to June 2014, in Shanghai Tongji Hospital, 119 patients who were diagnosed as perforated peptic ulcers and planned to receive operation were prospectively enrolled. Patients were randomly divided into LR (58 patients) and OR(61 patients) group by computer. Intra-operative and postoperative parameters were compared between two groups. This study was registered as a randomized controlled trial by the China Clinical Trials Registry (registration No.ChiCTR-TRC-11001607).</p><p><b>RESULTS</b>There was no significant difference in baseline data between two groups (all P>0.05). No significant differences of operation time, morbidity of postoperative complication, mortality, reoperation probability, decompression time, fluid diet recovery time and hospitalization cost were found between two groups (all P>0.05). As compared to OR group, LR group required less postoperative fentanyl [(0.74±0.33) mg vs. (1.04±0.39) mg, t=-4.519, P=0.000] and had shorter hospital stay [median 7(5 to 9) days vs. 8(7 to 10) days, U=-2.090, P=0.001]. In LR group, 3 patients(5.2%) had leakage in perforation site after surgery. One case received laparotomy on the second day after surgery for diffuse peritonitis. The other two received conservative treatment (total parenteral nutrition and enteral nutrition). There was no recurrence of perforation in OR group. One patient of each group died of multiple organ dysfunction syndrome (MODS) 22 days after surgery.</p><p><b>CONCLUSION</b>LR may be preferable for treating perforated peptic ulcers than OR, however preventive measures during LR should be taken to avoid postopertive leak in perforation site.</p>

Clinical application of compound anastomotic device in protective terminal ileostomy during rectal cancer operation / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical effect of the application of "compound anastomotic device" on the high-risk colorectal anastomosis in rectal cancer patients undergoing protective ileostomy.</p><p><b>METHODS</b>A total of 116 rectal cancer patients undergoing surgical procedure and prophylactic ileostomy in Tongji Hospital (90 cases) and The Third People's Hospital of Jingdezhen City (26 cases) from May 2011 to October 2016 were prospectively enrolled in the study. Paralleled control study and random digital table were applied. Fifty-eight cases received the compound anastomotic device for protective ileostomy (anastomosis ring group) and 58 cases underwent traditional terminal ileostomy (traditional group). The compound device was mainly composed of Valtrac biodegradable anastomosis ring, drainage tube and condom. Operational procedure was as follows: Ileocecum was freed through incision following laparoscopic total mesorectal excision; Two intestinal ring-shape purses were made; Intestinal wall between purse string was cut and the compound anastomotic device was put into; The purse was tightened and anastomosis ring was closed; The compound device was embed and pull out through the Trocar hole in the right lower abdomen; Then the drainage tube was fixed to the abdominal wall and connected with a drainage bag or an outer pocket. Incidence of anastomotic leak, stoma-related complications, hospital stay and total cost of two groups were compared.</p><p><b>RESULTS</b>The general clinical data between two groups were not significantly different(all P>0.05). Stoma operation was performed successfully in all the patients of two groups. The stoma operation time was (34.6±13.8) min in anastomosis ring group and (25.8±14.0) min in traditional group with significant difference (t=2.123, P=0.035). Postoperative anastomotic leak occurred in 7 cases, including 3 cases with small fistula in traditional group and 4 cases in anastomosis ring group, of whom 1 case underwent left-low abdominal colonic stoma after necrotic intestine resection. All the patients were discharged within postoperative 7 to 37 days. In traditional group, 35 cases (60.3%) occurred stoma-related complications, the total hospitalization expenses was (65±28) thousand yuan, and the average hospital stay (including stoma reversion) was (23.6±11.8) days. In anastomosis ring group, 17 cases (29.3%) occurred stoma-related complications, the total hospitalization expense was (52±11) thousand Yuan, and the average hospital stay was (21.0±16.8) days. The incidence of anastomotic fistula and the hospital stay had no significant difference between two groups (all P>0.05). The stoma-related complication morbidity (χ=3.216, P=0.002) and the total hospitalization expenses (t=2.683, P=0.027) in anastomosis ring group were significantly lower than those in traditional group.</p><p><b>CONCLUSION</b>Compared with traditional ileostomy, the application of compound anastomotic device for protective ileostomy would be better to benefit the recovery of patients.</p>

Status and progress of the research of preventing anastomosis leakage / 国际外科学杂志

Anastomotic leak belongs to the serious complications of low anterior resection with high morbidity and fatality.In recent decades,many strategies aimed at lowering the incidence of anastomotic leakage have been developed.This review focused on the methods for preventing anastomotic leakage through searching PudMed and Wanfang data for all related papers.Strategies were categorised as defunctioning stoma,transcecal catheter ileostomy,indwelling rectal tube,valtrac-secured intracolonic bypass technique,free take-back ileostomy.Every strategy has its own advantages and disadvantages.But to date,except defunctioning stoma,none of the methods has been widely accepted due to the lack of high level evidences.However,free take-back ileostomy can avoid stoma related complication and readmission for closure and its initial effect is good,so deserve to further research.

New concept and prospect of fast track surgery in the gastrointestinal surgery / 国际外科学杂志

Fast track surgery(FTS)is an idea and theory which has widely used in the surgical operations,through the whole treatment of patient' s surgery. A series of positive measures has been adopted, FTS has ameliorated the velocity of the rehabilitation and prognosis after operation, and improved the quality of life and the therapeutic effect. We reviewed the new concept and the application prospect of FTS in the gastrointestinal surgery in this article.
