Clinical Application of Mucosal Valve Technique for Anastomosis During Esophagogastrostomy

Background

The study aims to compare the efficacy in prevention of anastomotic complications using layer-to-layer mucosal valve technique versus circular stapled technique for esophagogastric intrathoracic anastomosis after resection for esophageal and gastric cardiac carcinoma.

Methods

From January 2005 to December 2010, 136 patients received layer-to-layer mucosal valve technique (LM group), 219 received circular stapled anastomosis (CS group) after curative intent resection for esophageal and gastric cardiac carcinoma. The technique details were reported and the clinical results were analyzed.

Results

The two groups were comparable on clinical baseline characteristics. The average duration of operation was longer with LM technique by 16 min, but without statistical significance (P?=?0.073). There was no anastomotic leakage in the LM group, while in the CS group, leakage occurred in seven patients (3.2 %, P?=?0.047). Both the incidence and grade of postoperative dysphagia were significantly lower in the LM group (P?<?0.05). Significantly fewer patients experienced stricture after LM technique (3.8 %) compared with CS anastomosis (18.2 %, P?<?0.001). CS anastomosis was associated with a significantly higher incidence of persistent stricture requiring more dilatation (P?<?0.001). Symptoms of reflux were better controlled by LM technique; 82.7 % of patients were asymptomatic with respect to reflux compared to 58.9 % in the CS group, P?<?0.001. And there was a significant reduction in the incidence of esophagitis in remnant esophagus in the LM group (P?=?0.001).

Conclusions

The layered mucosal valve anastomosis could significantly diminish the incidence of anastomotic complications and could be used as an alternative for esophagogastric anastomosis after resection of esophageal and gastric cardiac carcinoma.     

Embedded Cervical Esophagogastrostomy: A Simple and Convenient Method Using a Circular Stapler After Esophagectomy for Esophageal Carcinomas

Background

Cervical esophagogastrostomy is currently the most common method for esophageal reconstruction after esophagectomy. The advantages and disadvantages of hand-sewn, linear-stapled, or circular-stapled anastomoses have been subject to debate in recent years. We explored a new method of end-to-side anastomosis using a circular stapler that embeds the anastomosis and the remaining esophageal tissue into the gastric cavity to reduce the occurrence of anastomotic leakage and to prevent gastroesophageal reflux.

Methods

In 127 patients with esophageal carcinomas, end-to-side anastomoses with esophageal embedding were performed by connecting the anvil and body of the circular stapler inside the stomach before firing and embedding the anastomosis and remaining esophagus into the stomach after esophagectomy. Retrospective investigations on postoperative complications such as leakage, stricture, and gastroesophageal reflux were conducted.

Results

A total of 123 patients (96.9 %) had successful surgery, and 4 patients (3.3 %) developed anastomotic leakage, with the total morbidity of 20 of 123 (16.3 %) and in-hospital mortality of 1 of 123 (0.8 %). The incidence of stricture (<1 cm) affected 14 of 123 patients (11.4 %). Eight patients underwent dilatation treatment as a result of severe dysphagia (6.5 %). Half of the patients [62 of 123 (50.4 %)] experienced postoperative heartburn, 11 of 123 patients (8.9 %) experienced acid regurgitation, and 16 of 123 patients (13.0 %) experienced nocturnal cough.

Conclusions

Embedded cervical esophagogastrostomy with circular stapler is a simple and convenient method, with low incidence of anastomotic leakage and a good antireflux effect.     

Linear Stapled Esophagogastrostomy is more Effective than Hand-Sewn or Circular Stapler in Prevention of Anastomotic Stricture: a Comparative Clinical Study

Objective  

The aim of this study was to retrospectively compare the operative effects of linear stapled intrathoracic esophagogastrostomy with hand-sewn or circular stapled anastomosis in prevention of anastomotic stricture.     

食管胃套接术与器械吻合术治疗食管、贲门癌的对比研究

应用直线型缝合器行食管胃侧侧吻合术

目的探讨在食管不同手术入路中应用直线型缝合器行食管胃吻合以减少术后吻合口狭窄的效果。方法自2008年1月~2009年10月应用直线型缝合器纵向缝合食管胃吻合口后壁,使吻合口后壁延长至3 cm以上,应用可吸收缝线连续缝合吻合口前壁,完成食管胃侧侧吻合12例。术后随访观察进食情况,纤维胃镜、造影评估吻合口内径。结果12例均顺利完成食管胃吻合术,胸内吻合10例(83.3%),颈部吻合2例(16.7%)。经左胸切口行食管胃弓下吻合6例,经左胸切口行食管胃弓上吻合2例,经腹部正中切口、右胸切口行食管胃胸顶吻合2例,经三切口行食管胃颈部吻合2例。术后无吻合口瘘,切缘无癌残留,但发生腹部切口感染1例。术后随访1~18个月,进食通畅,行胃镜检查4例,造影检查8例,吻合口直径平均1.5(1.4~1.7)cm,无吻合口狭窄。结论应用直线型缝合器行食管胃吻合通过增加吻合口内径、改变吻合口位置减少了术后吻合口狭窄的发生,是替代传统管型吻合器吻合的有效手术方法。     

Randomized Trial Comparing Side-to-Side Stapled and Hand-Sewn Esophagogastric Anastomosis in Neck

Background

Leak from cervical esophagogastric anastomosis (CEGA) following esophagectomy is associated with morbidity and poor functional outcome. To address this issue, we conducted a randomized trial comparing ??hand-sewn?? with ??stapled side-to-side?? CEGA.

Methods

Of 174 patients who underwent esophageal resection and CEGA between 2004 and 2010, 87 each were randomized to ??hand-sewn?? and ??stapled side-to-side?? CEGA [www.Clinical Trials.gov: NCT00497549]. The primary outcome measure was anastomotic leak rate. The secondary outcome measures included CEGA construction time and occurrence of anastomotic stricture during follow up.

Results

The overall anastomotic leak rate was 17.2?% (major leaks: 8?%). The leak rate was similar among the two groups (hand-sewn: 14/87, stapled: 16/87; p?=?0.33). The stapled anastomotic technique was faster (25?±?6.5?min vs. 27?±?5.5?min; p?=?0.02). The overall operative mortality and morbidity rates were 6.3?% and 40.8?%, respectively. At a median follow up of 12 (6?C42) months, anastomotic stricture occurred in 24 (14.7?%) patients and was significantly more common in the ??hand-sewn?? group (17/82 vs. 7/81; p?=?0.045).

Conclusion

There were no differences in the leak rates and postoperative outcome between the two CEGA techniques. At follow up, anastomotic strictures occurred less frequently following stapled CEGA. The ideal CEGA technique remains elusive.     

Comparison of manual and mechanical cervical esophagogastric anastomosis after esophageal resection for squamous cell carcinoma: a prospective randomized controlled trial

Objective: The use of a circular stapler in cervical esophagogastric anastomosis remains controversial. This study was to compare the postoperative and long-term results of manual and mechanical techniques for cervical esophagogastric anastomosis after resection for squamous cell carcinoma. Methods: A prospective randomized controlled trial was undertaken in 63 patients with curatively resectable squamous cell cancer of the thoracic esophagus between 1996 and 1999. Patients were randomized to receive either a hand-sewn (32 patients) or circular stapled (31 patients) cervical esophagogastric anastomosis. Results: The mean operating time was longer when the hand-sewn method was used (524 vs. 447 min, P<0.001). Anastomotic leakage was noted in seven patients (22%) in the hand-sewn group and eight patients (26%) in the stapler group (P=NS). Hospital mortality occurred in four patients (13%) of the hand-sewn group and in three patients (10%) of the stapler group (P=NS). After the operation, four patients (14%) in the hand-sewn group and five patients (18%) in the stapler group developed a benign esophageal stricture (P=NS). The mean follow-up time was 24 months, and the rates of freedom from benign stricture and survival were comparable in each group. Conclusions: Performing cervical esophagogastric anastomoses using a circular mechanical stapler had a shorter operating time and a comparable outcome to the hand-sewn method. The circular mechanical stapler could be used as an alternative for cervical esophagogastric anastomosis after resection for esophageal squamous cell cancer.     

Technical Factors that Affect Anastomotic Integrity Following Esophagectomy: Systematic Review and Meta-analysis

Background

Due to the significant contribution of anastomotic leak, with its disastrous consequences to patient morbidity and mortality, multiple parameters have been proposed and individually meta-analyzed for the formation of the ideal esophagogastric anastomosis following cancer resection. The purpose of this pooled analysis was to examine the main technical parameters that impact on anastomotic integrity.

Methods

Medline, Embase, trial registries, and conference proceedings were searched. Technical factors evaluated included hand-sewn versus stapled esophagogastric anastomosis (EGA), cervical versus thoracic EGA, minimally invasive versus open esophagectomy, anterior versus posterior route of reconstruction and ischemic conditioning of the gastric conduit. The outcome of interest was the incidence of anastomotic leak, for which pooled odds ratios were calculated for each technical factor.

Results

No significant difference in the incidence of anastomotic leak was demonstrated for the following technical factors: hand-sewn versus stapled EGA, minimally invasive versus open esophagectomy, anterior versus posterior route of reconstruction and ischemic conditioning of the gastric conduit. Four randomized, controlled trials comprising 298 patients were included that compared cervical and thoracic EGA. Anastomotic leak was seen more commonly in the cervical group (13.64 %) than in the thoracic group (2.96 %). Pooled analysis demonstrated a significantly increased incidence of anastomotic leak in the cervical group (pooled odds ratio = 4.73; 95 % CI 1.61–13.9; P = 0.005).

Conclusions

A tailored surgical approach to the patient’s physiology and esophageal cancer stage is the most important factor that influences anastomotic integrity after esophagectomy.     

Clinical Application of Layered Anastomosis During Esophagogastrostomy

The aim of this study was to compare the operative results in regard to reducing anastomotic leakage and stricture formation using a newly designed layered manual esophagogastric anastomosis versus a stapler esophagogastrostomy versus the conventional hand-sewn whole-layer anastomosis after resection for esophageal or gastric cardiac carcinoma. From January 2004 to September 2006, a total of 1024 patients with esophageal or gastric cardia carcinoma underwent a layered esophagogastric anastomosis with the assistance of a three-leaf clipper in a single university medical center. The mucosal layers of the esophagus and stomach were sutured continuously with 4/0 Vicryl plus antibacterial suture (polyglyconate). From May 2002 to December 2003, there were also 170 patients and 69 patients who underwent stapler and conventional whole-layer anastomosis, respectively; they served as control groups. The results were analyzed retrospectively. The operative mortality rate was 0.7% in the layered group compared to 5.9% and 7.2% for the stapler group and the whole-layer group (p < 0.01), The anastomotic leakage rates were 0%, 3.5%, and 5.8% for the layered group, stapler group, and whole-layer group, respectively (p < 0.01). All patients were followed postoperatively. Six patients in the layered group (0.6%) developed mild stricture formation compared to 16 patients in stapled group (9.9%) and 5 patients in the conventional whole-layer group (7.8%) (p < 0.01). The application of layered esophagogastric anastomosis could reduce the incidence of anastomotic leakage and stricture after esophagectomy compared with the stapler and whole-layer manual anastomoses. It is easy to apply and could be used as an alternative for esophagogastric anastomosis after resection for esophageal or cardiac carcinoma. This abstract was accepted as a free paper and oral presentation at International Surgical Week 2007, Abstract 320, Montreal, Canada, August 2007     

Stapled versus hand-sewn pediatric intestinal anastomoses: A retrospective cohort study

Background

Whereas the adult literature has demonstrated the acceptable safety profile of stapled anastomoses when compared to the hand-sewn alternative, the choice of intestinal anastomosis using sutures or staples remains inadequately investigated in children. The purpose of this study is to compare the anastomotic outcomes of both techniques in children under 5 years of age.

Modified triangulating stapling technique for esophagogastrostomy after esophagectomy for esophageal cancer

Background

Anastomosis performed during esophagectomy for esophageal cancer is usually involves hand-sewn or circular stapled methods. However, these techniques have been reported to be associated with a high frequency of anastomotic complications, including leakage and benign stenosis. Here a novel triangulating stapling technique for esophagogastrostomy after esophagectomy for esophageal cancer and its retrospective investigation are described.

Methods

Forty-eight patients were underwent esophagectomy for esophageal cancer from January 2006 to December 2009 by the same surgeon using the triangulating stapling technique. The short-term outcomes were evaluated retrospectively. This end-to-end anastomosis used three linear staplers in an everted fashion.

Results

Patients comprised 36 men and 12 women with a mean age of 59.4 years. Anastomotic leakage occurred in 4 patients (8.3 %), while anastomotic stenosis was observed in 6 (12.5 %). The average number of endoscopic pneumatic dilatations in patients with anastomotic stenosis was 2.4. The median (range) duration of hospital stay was 40.8 (19–154) days.

Conclusions

Our modified triangulating stapling technique for esophagogastrostomy may be a feasible alternative, resulting in a lower frequency of postoperative anastomotic complications.     

半机械吻合与手工吻合对食管癌切除食管胃吻合口并发症发生率影响的系统评价与Meta分析

目的分析食管癌切除术后患者行食管胃半机械吻合与手工吻合对患者术后吻合口并发症发生率影响的差异。方法计算机检索PubMed、OVID数据库、中国期刊全文数据库（CNKI）、中国生物医学文献数据（CBM）,检索时间均从建库至2013年12月,并手工检索相关杂志,纳入比较半机械吻合与手工吻合对食管癌术后患者吻合口并发症发生率影响的随机对照研究或观察性研究。评价纳入文献质量、提取数据,采用RevMan 5.2软件进行Meta分析。结果共纳入12篇文献,包括随机对照试验3篇,观察性研究9篇,共1 271例患者。各研究间无统计学异质性,故采用固定效应模型进行Meta分析。结果显示两组患者术后吻合口瘘发生率差异有统计学意义[随机对照研究RR=0.34,95%CI（0.12,0.97）,P〈0.05;观察性研究OR=0.40,95%CI（0.26,0.62）,P〈0.05]。12篇文献均报道了患者术后吻合口狭窄发生率,Meta分析结果显示两组患者术后吻合口狭窄发生率差异有统计学意义[随机对照研究RR=0.14,95%CI（0.04,0.47）,P〈0.05;观察性研究OR=0.22,95%CI（0.15,0.34）,P〈0.000 1]。结论与手工吻合比较,食管癌切除术后患者食管胃半机械吻合能降低吻合口瘘和吻合口狭窄的发生率。由于纳入研究数量偏小,质量不高,上述结论仍需大样本、高质量的随机或非随机对照试验进一步验证。     

Comparison of hand-sewn and stapled esophagogastric anastomosis after esophageal resection for cancer: a prospective randomized controlled trial.

OBJECTIVE: The objective of this study was to compare the hand-sewn and stapled methods in esophagogastric anastomosis. SUMMARY BACKGROUND DATA: After esophageal resection for cancer, the relative merits of the hand-sewn and the stapled methods of esophagogastric anastomosis, especially regarding leakage and stricture rates, have not adequately been studied. METHODS: A prospective randomized controlled trial was undertaken in 122 patients with squamous cell cancer of the thoracic esophagus who underwent a Lewis-Tanner esophagectomy. Patients were stratified according to esophageal size, based on the diameter of the divided esophagus (< or > or = 30 mm) and then were randomized to have either a hand-sewn or a stapled anastomosis. RESULTS: The mean total operating times (standard error of the mean) when the hand-sewn and the stapled methods were used were 214 (4) minutes and 217 (3.4) minutes, respectively (p = not significant [NS]). The respective in vivo proximal resection margins (standard error of the mean) were 8 (0.4) cm and 7.6 (0.4) cm (p = NS). Leakage rates were 1.6% and 4.9% (p = NS). Excluding hospital deaths, patients with leakage or anastomotic recurrence, and those who received radiation therapy to histologically infiltrated resection margin, anastomotic stricture was found in 5 (9.1%) of 55 patients in the hand-sewn group and 20 (40%) of 50 in the stapler group (p = 0.0003). The difference in stricture rates was significant in small as well as large esophagi. Anastomotic recurrence developed in only one patient in each group. CONCLUSIONS: The authors conclude that both methods were safe, but the stapled technique resulted in more stricture formation.     

End-to-End Cervical Esophagogastric Anastomoses Are Associated with a Higher Number of Strictures Compared with End-to-Side Anastomoses

Background

Leakage and benign strictures occur frequently after esophagectomy. The objective of this study was to analyze the outcome of hand-sewn end-to-end versus end-to-side cervical esophagogastric anastomoses.

Methods

A series of 390 consecutive patients who underwent esophagectomy with gastric conduit reconstruction was analyzed.

Results

The end-to-end technique was performed in 112 (29 %) patients and the end-to-side in 278 (71 %) patients. Anastomotic leakage occurred in 20 (18 %) patients with an end-to-end anastomosis versus 58 (21 %) patients with an end-to-side anastomosis (p?=?0.50). A higher incidence in anastomotic strictures was seen in end-to-end anastomoses (48 (43 %)) compared with end-to-side anastomoses (89 (32 %); p?=?0.04). Moreover, a median of 11 (7–17) dilations was necessary in patients with a benign anastomotic stricture in the end-to-end group compared with four (2–8) dilations in patients with a benign anastomotic stricture in the end-to-end group (p?<?0.036). After multivariate analysis, the difference in anastomotic leakage rates remained nonsignificant (p?=?0.74), whereas anastomotic stricture rate and number of dilations were higher in the end-to-end group (p?=?0.03 and p?=?0.01, respectively).

Conclusion

The technique of anastomosis is not significantly related to anastomotic leakage rate. However, patients with end-to-end anastomoses develop postoperative strictures more frequently, requiring a higher number of dilations compared to end-to-side anastomoses.     

Circular Stapler Size and Risk of Anastomotic Complications in Gastroduodenostomy for Gastric Cancer

Background

A Billroth I reconstruction with a mechanically sutured anastomosis is commonly performed in gastric cancer patients. Some surgeons prefer to use large circular staplers during suturing to minimize risks for anastomotic stricture and gastric stasis after surgery. The effect of stapler size on anastomotic complications has not been validated.

Methods

This study was conducted with 1,031 patients who underwent gastrectomy and Billroth I reconstruction at Samsung Medical Center in Seoul, Korea, between January 2007 and October 2008. Patients were assigned to group A (384 patients) or group B (647 patients) depending on the size of the circular stapler that the surgeon selected for mechanical anastomosis. A 25?mm circular stapler was used for patients in group A, and a 28 or 29?mm circular stapler was used for patients in group B. Postoperative complications were analyzed retrospectively.

Results

The incidence of complications (e.g., gastric stasis, anastomotic stricture, and bleeding) did not differ significantly between groups. Age greater than 60?years was the only significant risk factor for anastomotic complications identified in univariate and multivariate analyses.

Conclusions

Stapler size was unrelated to complications, such as stricture and gastric stasis. Age was the only significant risk factor for anastomotic complications after gastroduodenostomy.     

Endoscopic Evaluation of the Quality of the Anastomosis After Esophagectomy with Gastric Tube Reconstruction

BACKGROUND: The morbidity and mortality of anastomotic complications after esophagectomy have gradually decreased in recent years. However, swallowing difficulties and reflux continue to burden patients jeopardizing their quality of life. In the present study we performed endoscopic evaluation of the outcomes of esophagogastrostomy by analyzing the presence of anastomotic stenosis and reflux esophagitis. METHODS: A retrospective analysis was carried out on 74 patients who underwent esophagogastrostomy after esophagectomy by one surgeon between January 1995 and December 2004. Fifty-three patients had an endoscopic examination during follow-up (29 +/- 23.6 months, range = 5-111 months). Reflux esophagitis and stenosis at the anastomostic site were analyzed according to the surgical technique used and the location of the esophagogastrostomy. RESULTS: The mean age at the time of repair was 60.3 +/- 8.87 (range = 39-81) years. Cervical anastomosis was performed in 26 patients and intrathoracic anastomosis in 27 patients. No significant statistical difference in the frequency of anastomotic stenosis was observed between the two groups (p = 0.829); reflux esophagitis was noted in three patients in the cervical anastomosis group and in 14 patients in the intrathoracic anastomosis group (p = 0.041). For all patients, 23 received a hand-sewn esophagogastric anastomosis and 30 a circular stapled one. There was no significant statistical difference in anastomotic stenosis (p = 0.689) and reflux esophagitis (p = 0.879) in comparisons between the two groups. CONCLUSION: Cervical anastomosis resulted in a better outcome for esophagogastrostomy by lowering the risk of reflux esophagitis; this outcome might improve the patient's quality of life.     

Differences in Early Complications between Circular and Linear Stapled Gastrojejunostomy in Laparoscopic Gastric Bypass

Background

Laparoscopic gastric bypass (LGBP) is the most common bariatric procedure worldwide. The gastrojejunostomy can be stapled with a circular or linear stapler, each with their own specific advantages. We have evaluated differences in postoperative complications between the two techniques.

Methods

We studied operative data and postoperative complications in 560 patients (79.8 % females, median age 42, BMI 42.5) operated with LGBP between 2008 and 2012 at our center. The gastrojejunostomy was initially performed using a circular stapler (CS) in 288 patients and later by linear stapler (LS) in 272. Complications, operative time, and length of stay were retrieved from our database. The risk of developing a port site infection was evaluated with multivariate logistic regression.

Results

Port site infections were more common with CS than LS, 5.2 and 0.4 %, respectively (p?<?0.01). Multivariate analysis demonstrated CS to be an independent risk factor for port site infections (OR 16.3 (2.09–126), p?<?0.01), as well as for stomal ulcers (OR 10.1, 1.15–89, p?=?0.04). Major postoperative complications remained unchanged (anastomotic leak 1.0 vs. 1.1 %, abscess 0.7 vs. 0.4 %), while operative time and length of stay were found to be shorter using the LS (122 vs. 83 min, p?<?0.001 and 4 vs. 3 days, p?<?0.001).

Conclusions

The linear stapled technique yielded lower incidence of port site infections, probably by avoiding the passage of a contaminated circular stapler through the abdominal wall. No difference in major complications was seen, but operative time was shorter using a linear stapler instead of a circular stapler.     

全腔镜食管癌三野根治术颈部机械吻合与手工吻合的应用比较

目的：评估全腔镜食管癌三野根治术食管胃颈部吻合方式（机械或手工）对术后吻合口相关并发症发生的影响。方法回顾性分析2010年1月至2013年11月间在福建省肿瘤医院胸外科接受全腔镜食管癌三野根治术治疗的203例食管癌患者的临床资料。根据颈部吻合方式的不同,分为机械吻合组（104例）和手工吻合组（99例）。比较两组患者术后吻合口相关并发症发生率。结果机械吻合组术中吻合时间较手工吻合组明显缩短[（15．5±5．0） min比（28．0±4．5） min,P＜0．01]。两组术后吻合口瘘发生率分别为5．8％（6/104）和3．0％（3/99）,差异无统计学意义（P＞0．05）;吻合口狭窄发生率分别为9．6％（10/104）和2．0％（2/99）,差异有统计学意义（P＜0．05）。结论与手工吻合相比,全腔镜食管癌三野根治术食管胃颈部机械吻合操作简单、吻合确切,但吻合口狭窄的风险增加,因此,在临床实践中,应结合患者的具体情况合理选择吻合方式。
