目的比较全层连续缝合法和分层缝合法在急诊腹部手术中的切口愈合效果。 方法将符合纳入标准的急诊腹部手术患者随机分为全层缝合组和分层缝合组，比较2组患者的切口愈合效果。 结果全层缝合组的关腹时间短于分层缝合组（P=0.000），但在切口液化发生率、切口感染发生率、总切口并发症发生率、切口愈合及术后住院时间方面，2组的差异均无统计学意义（P＞0.05）。26例细菌培养结果为阳性（全层缝合组10例，分层缝合组16例）的患者中，致病菌主要为大肠埃希菌（11例）和铜绿假单胞菌（7例）。 结论相较于分层缝合法，急诊腹部手术中采用全层缝合法既不增加切口并发症的发生率，又节省手术时间，对于危重患者具有重要的意义。
Objective To summarize and analyze the treatment options and prognostic factors of gastric stump carcinoma （GSC）. Methods The clinical data of 114 patients with GSC treated in The Second Affiliated Hospital of Northern Sichuan Medical College and The General Hospital of Chinese People’s Liberation Army from Mar. 2000 to May.2008 were reviewed， and influencing factors of surgical resection and prognosis were analyzed. Results For all patients，the ratios of surgical resection and curative resection（R0 resection） were 57.0%（65/114） and 54.4% （62/114）， respec-tively. The ratios of total gastrectomy， distal gastrectomy， proximal gastrectomy， endoscopic mucosal resection （EMR），and endoscopic submucosal dissection （ESD） were 73.8%（48/65）， 16.9%（11/65）， 3.1%（2/65）， 4.6%（3/65）， and 1.5%（1/65）in resection cases， and were 75.8%（47/62）， 16.1%（10/62）， 3.2%（2/62）， 4.8%（3/62）， and 0 in R0 resection cases， respectively. Seventy-five patients were followed-up for 0.3-79 months （median 12 months）， the mediansurvival time was 19.5 months， and 1-， 3-， and 5-year overall survival rates were 61.8%， 42.3%， and 30.1%， respectively. The results of multivariate analysis showed that resection rate was higher in patients with initial distalgastrectomy （P=0.002）， kps score≥80 （P=0.016）,lower macroscopic type （P=0.013）， and cM0 （P=0.000）. R0 resection （P=0.000）， macroscopic type （P=0.005）， and cT stage （P=0.006） were the independent prognostic factors. There were both no significant difference on survival between the patients with previous benign disease and those with original malignant disease when analyzed with univariate or multivariate method （P＞0.05）. There were no significant difference on overall survival curve among patients treated with palliative resection， palliative chemotherapy， simple laparotomy， and best supportive care （P＞0.05）. Conclusions The treatment options and prognosis of GSC were not influenced by the primary benign diseases or malignant diseases， and R0 resection is the most important prognostic factor. Removal of total remnant stomach is the best surgical procedure for GSC， and palliative laparotomy should be avoided.
Objective To analyze the clinicopathologic characteristics of remnant gastric cancer （RGC）. Methods The clinical data of 114 patients with RGC treated in The Second Affiliated Hospital of Northern Sichuan MedicalCollege and The General Hospital of Chinese People’s Liberation Army from March 2000 to May 2008 were reviewed and analyzed retrospectively. The clinicopathologic characteristics between the patients with primary benign diseases and those with malignant diseases were evaluated. Results A total of 114 cases，the age was （62.6±11.3） years，and the males versus females was 4.7∶1.0. Most patients （76.2%，64/84） were diagnosed at advanced stages （consistent with pT），and the proportion of pT1 stage cases was only 23.8% （20/84），tumor invasion pT4 was 60.7% （51/84）. It was more common that tumor directly invaded adjacent organs or structures （27.4%，23/84），lymph nodes positive （42.9%，36/84），and distant metastasis （27.2%，31/114）. The location of distant metastasis was usually confined in the abdominal cavity （93.5%，29/31），and the peritoneum disseminated was the most commonly structures （67.7%，21/31）. Histologically，the incidence of poorly differentiated adenocarcinoma （76.7%，79/103） was the mostly histologic grade as well as the diffuse type （78.6%，81/103） was the mostly Laurén classification. Between the patients with primary benign diseases and those with initial malignant disease，the initial gastrectomy or the methods of reconstruction had significantly differences （both P=0.000）. The median time from initial resection to development of RGC was 30.0 years in the patients with original benign disease，contrary to 3.3 years in those with previous malignant disease （P=0.000）. Both primary diseases （benign or malignant） and the age at initial gastrectomy were the major influencing factors for the time of RGC developed （P＜0.05）. For pathohistology characters，except signet-ring cell carcinoma （P=0.045）， pT4b （P=0.049），pN stage （P=0.025），and Borrmann classification （P=0.005），there were no significant differences between the patients with previous benign diseases and those with original malignant disease，as well as the resectability rate，curative resection （R0） rate，and overall survival rate （P＞0.05）. Conclusions It is almost unaffected by originalbenign diseases or malignant diseases for clinicopathologic characteristics including the treatment option and prognostic factors.It is necessary and feasibility to form a pattern of endoscopic follow-up for RGC.
