Utility of total mechanical stapled cervical esophagogastric anastomosis after esophagectomy: a comparison to conventional anastomotic techniques

BACKGROUND: Cervical esophagogastric anastomosis after esophagectomy is often troubled with anastomotic leak resulting in local sepsis, postoperative stricture, and prolonged hospitalization. We compared the anastomotic outcomes and clinical course of esophagectomy patients undergoing total mechanical stapled esophagogastric anastomosis versus a partial handsewn/mechanical stapled cervical anastomotic technique. METHODS: One hundred eighty-one patients underwent transhiatal (N=146) or 3-field (abdomen/chest/neck incisions) (N=35) esophagectomy. A total mechanical stapled anastomosis was accomplished in 125 patients. A handsewn/mechanical stapled anastomosis was performed in 56 patients. The total mechanical stapled anastomosis was accomplished by using the endoscopic gastrointestinal stapler to construct the posterolateral aspect and a linear stapler to close the anterior aspect of the anastomosis. Total mechanical stapled anastomosis patients had the endoscopic gastrointestinal stapler also used to divide the left gastric vessels and the short gastric mesentery for gastric mobilization. Anastomotic outcomes were analyzed by the leak rate (contrast study) and the need of serial dilations in each group. CONCLUSIONS: Total mechanical stapled technique after esophagectomy with cervical esophagogastric anastomosis appears to be effective in reducing hospitalization and anastomotic complications compared to partial or complete handsewn techniques. Liberal use of endoscopic staplers might shorten operative time. Esophageal surgeons should be aware of the advantages and become skilled with these techniques.     

Mechanical cervical esophagogastric anastomosis after esophagectomy for cancer

AIM: Fibrous stenosis of the esophagogastric cervical anastomosis remains a significant complication occurring in up to one third of cases. Trying to reduce the incidence of this complication, we describe our technique of cervical esophago-gastric anastomosis using endoscopic linear stapler which seems to reduce the incidence of fibrous stricture formation after resection of esophageal cancer. METHODS: Between March 2000 and December 2004, 34 patients (20 males and 14 females) underwent esophagectomy using tubulized stomach for reconstruction. Mean age was 57 years. Eight patients with advanced stage (5 T3 and 3 T4) underwent induction chemotherapy. The most of patients was affected by squamous cell carcinoma. In all cases we performed cervical esophagogastric anastomosis using linear endoscopic stapler. The occurrence of postoperative anastomotic leak and development of anastomotic stricture were recorded and analyzed. RESULTS: All patients survived esophagectomy and 30 of them (88%) were available for postoperative follow-up at 6 months. Anastomotic leak developed in 1 case. No patient developed fibrous stenosis that required dilatation therapy. CONCLUSIONS: Complete mechanical esophago-gastric anastomosis, using endoscopic linear stapler is effective and safe, even when a narrow gastric tube is used as esophageal substitute. These technique seems superior to other techniques to reduce the incidence of postoperative anastomotic complications.     

Complete mechanical cervical anastomosis using a narrow gastric tube after esophagectomy for cancer.

OBJECTIVE: Fibrous stenosis of the esophagogastric cervical anastomosis remains a significant complication occurring in up to one-third of cases. Trying to reduce the incidence of this complication, we describe our technique of cervical esophagogastric anastomosis using endoscopic linear stapler which seems to reduce the incidence of fibrous stricture formation after resection of esophageal cancer. METHODS: Between March 2000 and June 2003, 26 patients (15 males and 11 females) underwent esophagectomy using tubulized stomach for reconstruction. Cervical esophagogastric anastomosis using linear endoscopic stapler was performed in all cases. The occurrence of post-operative anastomotic leak and development of anastomotic stricture were recorded and analyzed. RESULTS: All patients survived esophagectomy and were available for post-operative follow-up. Anastomotic leak developed in one case. No patient developed fibrous stenosis that required dilatation therapy. CONCLUSION: Complete mechanical esophagogastric anastomosis, using endoscopic linear stapler is effective and safe, even when a narrow gastric tube is used as esophageal substitute. This technique seems superior to other techniques to reduce the incidence of post-operative anastomotic complications.     

Collare Anastomosenstenosen nach Magenhochzug beim Ösophaguskarzinom

Common late complications after esophagectomy and gastric tube reconstruction for esophageal carcinoma are symptomatic, benign fibrotic stenoses of the cervical anastomosis, which require dilatation. Since the prognosis of esophageal carcinoma still remains poor, bad functional results such as dysphagia affect quality of life. In a retrospective analysis, our patients were evaluated with regard to the underlying effects of cervical anastomotic stenosis after esophagectomy and gastric tube reconstruction. From 1 January 1989 to 31 July 1995, 173 patients with carcinoma of the esophagus were operated in our institution. Transhiatal esophageal dissection was performed in 133 patients; 40 patients underwent transthoracic en bloc resection. The 30-day mortality rate was 7.5% (13 patients). Postoperative fibrotic stenosis of the cervical anastomosis requiring dilatation occurred in 36.4% (63 patients) 6–12 weeks after operation. Fibrotic stenosis of the cervical anastomosis did not develop in 97 patients. There was a significant difference concerning the incidence of anastomotic leaks within both groups: whereas in 23.8% of the 63 patients who developed a fibrotic stricture of the cervical anastomosis an anastomotic leak preceded this event (P<0.001), no anastomotic leak occurred in the group of 97 patients with normal healing of the cervical anastomosis. In addition, significantly (P<0.01) more patients (37.5%,n=23) with preexisting diabetes mellitus could be found among the 63 patients who developed a fibrotic stricture of the cervical anastomosis, in contrast to the 97 patients without anastomotic stenosis.     

Eliminating the cervical esophagogastric anastomotic leak with a side-to-side stapled anastomosis

BACKGROUND: Although the acute postoperative complications of a cervical esophagogastric anastomosis are less than those with an intrathoracic esophageal anastomosis, the long-term sequelae of a cervical anastomotic leak are not as minor as initially reported. Nearly 50% of cervical anastomotic leaks result in an anastomotic stricture, and the subsequent need for chronic dilatations negates the merits of an operation intended to restore comfortable swallowing. OBJECTIVE: This study was undertaken to determine whether construction of a side-to-side stapled cervical esophagogastric anastomosis after transhiatal esophagectomy could reliably eliminate the majority of anastomotic leaks. METHODS: In 114 consecutive patients undergoing transhiatal esophagectomy, a functional side-to-side cervical esophagogastric anastomosis was constructed with the Auto Suture Endo-GIA II stapler (United States Surgical Corporation, Auto Suture Company Division, Norwalk, Conn) applied directly through the cervical wound. This side-to-side stapled anastomosis has 3 rows of staples. Early postoperative anastomotic morbidity, subsequent need for anastomotic dilatations, and patient satisfaction with swallowing were evaluated. RESULTS: Before the side-to-side stapled anastomosis, the incidence of cervical esophagogastric anastomosis leak in over 1000 patients undergoing transhiatal esophagectomy having a manually sewn anastomosis varied from 10% to 15%. Among the 111 survivors of transhiatal esophagectomy and a side-to-side stapled anastomosis, there were 3 (2.7%) clinically significant anastomotic leaks. This lowered incidence of leaks has contributed to reduction in the average length of stay after an uncomplicated transhiatal esophagectomy to 7 days and has provided more comfortable swallowing, ease of subsequent esophageal dilatations, and greater patient satisfaction. CONCLUSIONS: Construction of the cervical esophagogastric anastomosis with a side-to-side stapled anastomosis greatly reduces the frequency of anastomotic leaks and later strictures. The side-to-side stapled anastomosis is a major technical advance in the progression of refinements of transhiatal esophagectomy and a cervical esophagogastric anastomosis.

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.

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.     

Does esophagogastric anastomotic technique influence the outcome of patients with esophageal cancer?

OBJECTIVE: We sought to compare the outcome of patients with esophageal cancer who had either modified Collard or standard hand-sewn cervical esophagogastric anastomoses in reconstruction during esophagectomy. METHODS: From March of 1996 to October of 2002, 274 patients with esophageal cancer underwent esophagectomy with gastric replacement and cervical esophagogastric anastomosis. Beginning in March of 2001, a modified Collard technique (stapled) was used in most patients (n = 86) for cervical esophagogastric anastomosis; a standard hand-sewn technique (sewn) was used in all others (n = 188). Using a propensity score based on 8 variables (age, gender, race, surgeon, surgical approach, pathologic stage, histologic cell type, and induction chemoradiotherapy), 85 patient pairs were matched and followed for time-related events. Outcome comparisons included cervical wound infection, cervical anastomotic leak, other hospital complications, length of stay, anastomotic dilatation, reflux symptoms, and survival. RESULTS: At 30 days, freedom from cervical wound infection was 92% for stapled versus 71% for sewn anastomoses ( P = .001), and freedom from cervical anastomotic leak was 96% versus 89% ( P = .09), respectively. Other hospital complications occurred in 58% and 49%, respectively ( P = .17). Median length of stay was 10 days for both ( P = .3). At 2 years, freedom from anastomotic dilatation was 34% for stapled versus 10% for sewn anastomoses ( P < .0001), and the mean number of dilatations per patient was 2.4 versus 4.1 ( P = .0001), respectively. Reflux was rare for both. Thirty-day, 6-month, and 24-month survivals were 98%, 91%, and 77% for stapled anastomoses and 98%, 88%, and 69% for sewn anastomoses ( P = .3). CONCLUSIONS: The modified Collard anastomotic technique dramatically reduces morbidity after esophagectomy. It should replace hand-sewn esophagogastric anastomoses.     

食管胃套接术与器械吻合术治疗食管、贲门癌的对比研究

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.     

Cervical esophagogastric anastomosis with a new stapler in the surgery of esophageal carcinoma.

OBJECTIVE: A new reusable circular stapler for cervical esophagogastric anastomosis (CEGA) has been used to substitute the traditional method of hand-sewn cervical anastomosis. METHODS: Over a 2-year period (09/1998-11/2000), the stapler was engaged on operations of 112 patients with thoracic esophageal carcinoma, and the anastomosis was performed through both cervical and thoracic incision. The operative approaches were through left thoracotomy in 85 cases, and through right thoracotomy in 27 cases. The results were analyzed retrospectively. RESULTS: All of the 112 CEGA operations were successfully performed on the patients who underwent esophageal resections, and no operative mortality and anastomotic leakage occurred. Excluding the two patients with the anastomotic recurrent carcinoma, anastomotic stricture occurred in 12 cases (10.9%, n=110). Median time to the presentation of anastomotic stricture was 4.3 months (range 2.6-25.3 months), and the median number of dilatations was 3 (range 1-5). When divided into the 24 and 26 mm groups, the respective incidences of stricture were 12.3 (7/57) and 9.4% (5/53), respectively, and the statistical results of the two sizes of staplers were essentially the same (P=0.6691). Eight patients experienced nonanastomotic-related complications (7.3%, n=110), in which there were three cases of recurrent laryngeal nerve injury, four cases of the left side pneumothorax, and one case of perforation of the proximal stomach. There was also a case of stapling gauze at anastomosis. Some of the complications were closely related to the initially improper use of the new stapler's craft. CONCLUSIONS: The results indicate that CEGA using the new circular stapling device in surgery of the esophageal carcinoma is a very effective procedure to improve the anastomotic technique from a traditional hand-sewn anastomosis to a stapled anastomosis and can reduce the incidence of complications.

Clinical results using bioabsorbable staple line reinforcement for circular staplers

Although linear surgical staple line reinforcement has been shown to increase anastomotic tensile strength in animal models and reduce the incidence of staple line bleeding and anastomotic leaks in colorectal surgery, the benefits of staple line reinforcement on circular stapled anastomoses in bariatric surgery remain unreported in the literature. The purpose if this study was to compare the incidence of anastomotic bleeding, leak, and stricture in patients undergoing laparoscopic gastric bypass with circular staple line reinforcements with those with no circular staple line reinforcements. Since May 2006, 138 consecutive patients (Group B) have undergone laparoscopic Roux-en-Y divided gastric bypass with a 25-mm circular stapled gastrojejunal anastomosis using GORE SEAMGUARD bioabsorbable circular staple line reinforcement (CBSG) with a mean follow up of 9 months. The incidence of anastomotic bleeding, leak, and stricture was compared with 255 similar patients (Group A) who underwent surgery before May 2006 without gastrojejunal reinforcement with a mean follow up of 22 months. The rates of anastomotic bleeding, leak, and stricture for Group B versus Group A were 0.7 per cent versus 1.1 per cent (P = 0.64); 0.7 per cent versus 1.9 per cent (P = 0.34); and 0.7 per cent versus 9.3 per cent (P = 0.0005), respectively. The use of CBSG reduced the incidence of anastomotic stricture by 93 per cent and the incidence of a composite end point of all anastomotic complications by 85 per cent. Our results indicate that the use of circular staple line reinforcement at the gastrojejunal anastomosis in patients undergoing laparoscopic gastric bypass significantly decreases the incidence of anastomotic stricture and a composite end point of all anastomotic complications. On this basis, strong consideration should be given to the routine use of CBSG staple line reinforcement in patients undergoing laparoscopic divided gastric bypass with a circular stapled gastrojejunal anastomosis.

Experience and technique of stapled mechanical cervical esophagogastric anastomosis

BACKGROUND: Anastomotic leak from cervical esophagogastric anastomoses is a serious problem after esophagectomy. We explored the efficacy of partial or total mechanical anastomoses accomplished with the endoscopic linear cutting and stapling device as an alternative to hand-sewn anastomotic techniques. METHODS: During a 42-month period, 93 patients undergoing either transhiatal esophagectomy or a three-incisional approach to esophagectomy underwent either hand-sewn (n = 43), partial mechanical (n = 16), or totally mechanical (n = 34) cervical esophagogastric anastomoses. The occurrence of postoperative anastomotic leak and the development of postoperative anastomotic stricturing requiring dilation therapy were analyzed between these groups using chi2. RESULTS: All patients survived esophagectomy and were available for postoperative follow-up. Anastomotic leak developed in 10 patients (23%) with hand-sewn, 1 patient (6%) with partial mechanical, and 1 patient (3%) with total mechanical anastomoses (p < 0.05). Anastomotic stricture development paralleled the occurrence of anastomotic leak rate with 25 patients (58%) with hand-sewn, 3 patients (19%) with partial mechanical, and 6 patients (18%) with total mechanical anastomoses experiencing strictures requiring dilation therapy (p < 0.05). CONCLUSIONS: These results suggest that partial or mechanical cervical esophagogastric anastomoses created with the endoscopic stapling device may be superior to hand-sewn anastomotic techniques.     

机械吻合在食管外科中的应用：1605例经验总结

１９８０年８月至１９９４年２月应用机械方法对１６０５例食管癌和贲门癌切除后进行吻合。男１２８１例，女３２４例。年龄２８～８１岁，其中５０～６９岁１１８４例（７３．８％）。食管癌１０４４例，贲门癌５６１例。食管胃颈部吻合３５例；超胸顶吻合５８例；弓上吻合８３５例；弓下吻合６７７例。术后发生吻合口瘘１６例（ｌ％），其中颈部吻合口瘘发生率１４．３％（５／３５）；胸内吻合口瘘发生率０．７％（１１／１５７０），前６年胸内吻合口瘘发生率１．４％（８／５７５），近８年胸内吻合口瘘发生率０．３％（３／９９５）。术后发生吻合口狭窄１６例（１％），狭窄明显者经扩张后均恢复正常饮食。作者认为：机械吻合是减少胸内吻合口瘘的有效方法之一。
