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.

Endoscopic evaluation of gastric conduit perfusion in minimally invasive Ivor Lewis esophagectomy

IntroductionLaser-assisted indocyanine green (ICG) fluorescent dye angiography has been used in esophageal reconstructive surgery where it has been shown to significantly decrease the anastomotic leak rate. Recent advances in technology have made this possible in minimally invasive esophagectomy.Presentation of caseWe present a 69-year-old male with a cuT2N0M0 adenocarcinoma of the esophagus at the gastroesophageal junction who presented to our clinic after chemoradiation and underwent a minimally invasive Ivor Lewis esophagectomy. The perfusion of the gastric conduit was assessed intraoperatively using endoscopic ICG fluorescent imaging system. The anastomosis was created at the well-perfused site identified on the fluorescent imaging. The patient tolerated the procedure well, had an uneventful recovery going home on postoperative day 6 and tolerating a regular diet 2 weeks after the surgery.DiscussionCombination of minimally invasive surgery and endoscopic evaluation of perfusion of gastric conduit provide improved outcomes for surgical treatment for patients with esophageal cancer.ConclusionThe gastric conduit during minimally invasive Ivor Lewis esophagectomy can be evaluated using endoscopic ICG fluorescent imaging.     

Minimally invasive Ivor Lewis esophagectomy

Ivor Lewis esophagectomy consists of a laparotomy and right thoracotomy for resection of the intrathoracic esophagus. Recent advances in minimally invasive surgical technology have allowed surgeons to apply laparoscopy and thoracoscopy to perform esophagectomy. However, there have been few reports that describe a totally minimally invasive Ivor Lewis esophagectomy. We present a case of combined laparoscopic and thoracoscopic resection of the distal third esophagus with an intrathoracic esophagogastric reconstruction for esophageal carcinoma.     

Anastomotic leakage after esophagectomy for cancer: a mortality-free experience

BACKGROUND: Leakage is a serious complication of esophagectomy and is historically associated with high mortality. This study aimed to describe the morphology and strategies for clinical management of leakage after esophagectomy. STUDY DESIGN: A database prospectively maintained from July 2002 to July 2005 at a referral unit for foregut cancer was used to identify patients with leakage of saliva or gastrointestinal contents after esophagectomy and reconstruction with stomach. Contrast swallow was routinely performed on postoperative day 7. Leakage was diagnosed and classified by well-defined criteria. RESULTS: There were 99 men and 27 women, yielding an institutional volume of 42 esophagectomies per year. There was no in-hospital mortality from any cause. Actual 1-year survival was 87%. An Ivor Lewis operation was performed on 103 patients (82%); 4 patients had leakage within 5 days of operation and all had immediate rethoracotomy. An additional 8 patients with Ivor Lewis operation had leakage after day 5, and this was detected by contrast swallow in only 3 patients; 2 patients had no intervention, 4 patients had radiology-guided drainage, 1 had thoracoscopy, and 1 had rethoracotomy. Leakage was from the actual esophagogastric anastomosis in eight patients, from the linear gastric staple line in three patients, or from gastric necrosis in one patient. Twenty-three patients had a transhiatal or three-stage operation; leakage was from the actual anastomosis in five patients or gastric necrosis in one patient. CONCLUSIONS: After Ivor Lewis esophagectomy, leakage was from the actual anastomosis in two-thirds of patients or from the gastric conduit in the remaining one-third. Prompt reoperation is recommended for early postoperative leakage. Most patients with leakage after day 5 can be treated nonoperatively.     

Robotic versus laparoscopic hepatectomy: application of the difficulty scoring system

The development of robotic system may help to relieve the difficulties encountered during laparoscopic hepatectomy. A difficulty scoring system (DSS) was developed to assess the difficulty of various laparoscopic liver resection procedures. The aim of this study is to explore if the DSS is applicable in robotic hepatectomy and to compare the outcomes of robotic hepatectomy and laparoscopic hepatectomy among different difficulty levels. Clinical data from all consecutive patients who underwent robotic and conventional laparoscopic hepatectomy at the Prince of Wales Hospital, Hong Kong, were prospectively collected and reviewed. The difficulty level of operations was graded using the DSS. Perioperative outcomes of robotic and conventional laparoscopic hepatectomy were compared at each difficulty level. A total of 107 and 94 patients underwent robotic and laparoscopic hepatectomy during the study period, respectively. Among them, 16 and 2 patients were operated for recurrent pyogenic cholangitis, respectively, and were excluded because no mark for tumour location can be assigned. For robotic hepatectomy, a higher DSS was significantly correlated with higher minor complication rate (p = 0.001), more intraoperative blood loss (p = 0.002), longer operation time (p < 0.001) and longer post-operative hospital stay (p < 0.001). The mean DSS scores of robotic and laparoscopic hepatectomy were 4.5 and 3.6, respectively. (p = 0.004). For cases with low (DSS 1–3) and intermediate (DSS 4–6) difficulty level, there was no significant difference in operative blood loss, operation time and overall complications rate. Only 2 cases (2.2%) with high difficulty level were operated with laparoscopic approach while 20% of patients operated with robotic approach had DSS > 6. DSS significantly correlated with surgical outcomes in patient who underwent robotic hepatectomy. Perioperative outcomes following robotic and conventional laparoscopic hepatectomy were similar in cases with low and intermediate difficulty. However, robotic system allowed minimally invasive approach in cases with higher difficulty level.     

Outcomes of Esophagectomy According to Surgeon’s Training: General vs. Thoracic

Introduction  Esophagectomy is performed by general and thoracic surgeons with the type of operation often dictated by the surgeons’ training. The objective was to investigate outcomes of esophagectomy to determine if they varied according to surgeon’s training. Methods  Clinical data of patients who underwent partial or total esophagectomy for esophageal cancer from 2003 through 2007 were obtained from the University HealthSystem Consortium database. Data were examined between general versus thoracic surgeon and were reviewed for number and type of operations performed, demographics, length of stay, and postoperative morbidity and mortality. Results  During the 54-month period, 2,657 esophagectomies were performed; 1,079 (41%) by general surgeons and 1,578 (59%) by thoracic surgeons. More blunt transhiatal esophagectomies were performed by general surgeons compared to thoracic surgeons (56% vs. 37%, p < 0.01) while more Ivor Lewis resections were performed by thoracic surgeons (63% vs. 44%, p < 0.01). Thoracic surgery certification did not significantly affected outcomes with regards to mean hospital and ICU stay, complications, observed mortality, and mortality index. Conclusions  In academic centers, the majority of esophagectomies for carcinoma are performed by thoracic surgeons who favor the Ivor Lewis approach, while general surgeons favor the blunt transhiatal approach. Despite these differences, specialty training does not appear an important factor affecting outcome.

Comparative Experience of Open and Minimally Invasive Esophagogastric Resection

Background  A minimally invasive approach to esophagogastric cancer resection offers an attractive alternative to traditional open surgery; however, concerns regarding feasibility, safety, cost, and outcomes have restricted widespread acceptance of these procedures. This study outlines our comparative experiences of both open and minimally invasive esophagectomy over a 4-year period. Methods  Surgical outcomes were analyzed and compared between 30 consecutive patients who underwent open (Ivor Lewis) transthoracic esophagectomy (TTO) between January 2002 and December 2003 and 50 consecutive patients who underwent minimally invasive esophagectomy (MIO) from January 2004 to July 2006. Results  Inpatient mortality and overall surgical morbidity were identical for each cohort (TTO versus MIO: mortality 3% versus 2%; morbidity 50% versus 48%). Pulmonary-related complications were higher in the open series (23% versus 8%; p = 0.05). The incidence of gastric-conduit-related complications was similar between the two cohorts (13% versus 18%; p = 0.52). Survival at 1 and 2 years was 86% and 58% in the TTO group and 94% and 74% in the MIO group. No significant difference in calculated cost was observed (￡7,017 versus ￡7,885). Conclusions  Transition from open to minimally invasive techniques of esophagogastric resection for cancer is possible without compromising patient safety or incurring excessive financial expenses, and the minimally invasive procedure results in similar or potentially better outcomes.     

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.     

Ivor Lewis' operation for epidermoid cancer of the esophagus. Immediate and late results. Apropos of 168 cases]

168 Ivor Lewis operations for squamous carcinoma of the lower esophagus are reviewed. 155 men and 13 women with a mean age of 59 years were operated on. 46 tumors were stage I and II, and 122 were stage III. Operations were considered to be curative for 120 patients and only palliative for 48. An esophagectomy associated with lymphadenectomy was performed through laparotomy and right thoracotomy. Feeding jejunostomy and pyloroplasty were routine. EEA or ILS 25 staplers were used to perform esophagogastric anastomosis and the gastroplasty tube was fashioned by TA 90 stapler. In every case an extended esophagectomy was performed with anastomosis between 3 ans 7 cm below the pharyngo-esophageal junction. Postoperative mortality was 4.7%. There were 10 leaks (6%) and 28 pulmonary complications. Median actuarial survival is 17 months. Actuarial survival at 2 years is significantly greater for stages I and II (68.4%) than for stage III (23.2%) (p < 0.01). Ivor Lewis esophagectomy is a reliable procedure to treat squamous carcinoma of the lower two thirds of the esophagus ensuring a good quality of life.     

Ivor Lewis esophagectomy with manual esogastric anastomosis by thoracoscopy in prone position and laparoscopy

Introduction  

Only a few authors have reported the technique of Ivor Lewis esophagectomy by minimally invasive means, and anastomosis was usually performed by a circular stapler. We report an Ivor Lewis esophagogastrectomy with manual esogastric anastomosis performed by thoracoscopy in the prone position.     

Hand-Sewn Cervical Anastomosis Versus Stapled Intrathoracic Anastomosis After Esophagectomy for Middle or Lower Thoracic Esophageal Cancer: A Prospective Randomized Controlled Study

Purpose The type of anastomosis and its outcome can affect postoperative morbidity, mortality, and quality of life after esophagectomy. We compared the outcomes of cervical hand-sewn anastomosis (CHS) and intrathoracic stapled anastomosis (ITS) performed after esophagectomy and gastric reconstruction. Methods Thirty-two patients with middle or lower thoracic esophageal cancer were prospectively randomized to undergo CHS (n = 18) or ITS (n = 14) after esophagectomy. We compared clinical data, postoperative symptoms, and long-term survival in the two groups. Results The rates of anastomotic leak and stricture in the CHS and ITS groups were 16.7% versus 7.1% and 0% versus 14.2%, respectively, which do not represent significant differences. The respective rates of recurrent laryngeal nerve palsy were 38.8% versus 7.1% (P < 0.05), and proximal esophageal resection was 15 mm longer (P < 0.05) in the CHS group. There were no significant differences in symptoms 6 months after surgery, or in the overall 5-year survival rates (72.2% and 85.7%, respectively). Conclusions The two methods of anastomosis yielded similar anastomotic outcomes. Although the incidence of recurrent laryngeal nerve injury was higher after CHS, and proximal esophageal resection was longer, this had little impact on postoperative symptoms and long-term survival.     

The triangulating stapling technique for cervical esophagogastric anastomosis after esophagectomy

Purpose  To evaluate the safety and feasibility of the triangulating stapling technique (TST) for cervical esophagogastric anastomosis after esophagectomy (CEGA). Methods  The subjects were 123 patients who underwent transthoracic esophagectomy with three-field lymph node dissection and reconstruction with a 3.5-cm wide gastric tube, for thoracic esophageal cancer. We performed the TST for CEGA in 33 patients operated on after December, 2006 (TST group) and hand-sewn anastomosis in 90 patients operated on between 2002 and 2006 (HSA group). Results  In the TST group, CEGA was performed in an end-to-end fashion using three linear staplers. The first anastomosis was applied to the posterior walls of the remnant esophagus and gastric tube in an inverted fashion. The second and the third anastomoses were done in an everted fashion to make the anterior wall. The end-to-end HSA was performed with interrupted sutures using 4-0 absorbable material. Anastomotic leakage occurred in only 1 (3.0%) of the 33 TST patients, but in 13 (14.4%) of the 90 HSA patients (P = 0.07). The frequency of anastomotic stenosis was 9.1% and 25.6% in the TST and HSA groups, respectively (P < 0.05). Conclusions  Cervical esophagogastric anastomosis using TST may reduce the frequency of anastomotic leakage and stenosis. This technique is a safe and reliable alternative for CEGA after esophagectomy.     

Outcomes of high versus low ligation of the inferior mesenteric artery with lymph node dissection for distal sigmoid colon or rectal cancer

We compared the complication rates and oncologic and functional outcomes of high versus low ligation of the inferior mesenteric artery (IMA). We reviewed data retrospectively from 776 patients, divided into high and low IMA ligation groups. Low ligation was performed with lymph node dissection around the IMA root. Postoperative complications and oncologic and functional outcomes were analyzed. There were 613 patients in the high ligation group and 163 patients in the low ligation group. Most clinicopathological variables were similar. There were no significant differences in complication rates (25.1% vs. 28.8%; p = 0.336), anastomotic leakage (2.8% vs. 2.5%; p = 1.000), colonic ischemia (2.8% vs. 1.2%; p = 0.393), 5-year overall survival (79.6% vs. 81.3%; p = 0.137) or 5-year relapse-free survival (77.4% vs. 73.3%; p = 0.973) between the groups. In terms of functional outcomes, both techniques were equivalent. The International Prostate Symptom Score and Fecal Incontinence Severity Index were significantly better in the low ligation group 12 months postoperatively than 3 months postoperatively. The oncologic and functional outcomes, as well as postoperative complications, after low ligation of the IMA with lymph node dissection are not significantly different from those after high ligation of the IMA.     

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.     

Comparison of oncological outcomes after laparoscopic transhiatal and open esophagectomy for T1 esophageal adenocarcinoma

Introduction  This study compared pathological characteristics and patterns of disease recurrence for patients with pT1 esophageal adenocarcinoma treated with either laparoscopic transhiatal esophagectomy or open esophagectomy. Methods  From January 2000-December 2006, 44 patients had pT1 esophageal adenocarcinoma after esophagectomy. No patients had neoadjuvant treatment. Twenty-four patients had an Ivor Lewis operation, 4 had an open transhiatal and 16 had a laparoscopic transhiatal operation. Results  There were 37 men. The median age was 64 years (range 35–80 years). Median lymph node yield was 19 (10–51) after an Ivor Lewis operation, 16 (3–28) after an open transhiatal operation and 15 (4–41) after a laparoscopic transhiatal operation. There were two in-hospital deaths (5%), both following open Ivor Lewis operation. All patients in the laparoscopic group had N0 disease; none received adjuvant treatment. Two patients (7%) in the open group had N1 disease, of whom one patient received adjuvant chemotherapy. Eleven patients had submucosal invasion. Alive patients had median follow-up of 36 months (range 5–87 months). One patient in the laparoscopic group had recurrence at 22 months. This patient had poorly differentiated N0 disease which was limited to the mucosa and died at 24 months. Two patients in the open group developed recurrence, at 6 months (N0 disease with submucosal invasion) and 8 months (N1 disease with submucosal invasion) and died at 7 and 14 months, respectively. Both patients had poorly differentiated tumours. The second patient with N1 disease is alive and well at 14 months. Estimated survival (Kaplan–Meier) at 3 years was 93%. Conclusions  As compared with open transthoracic esophagectomy, there is no oncological detriment in the treatment of pT1 esophageal adenocarcinoma by laparoscopic transhiatal esophagectomy. The incidence of recurrence is small (7%) but can occur even in patients with tumour limited to the mucosa or N0 disease.     

Construct Validation: Simulation of Thoracoscopic Intrathoracic Anastomosis

Background and Objectives:

We sought to develop a simulation model that accurately replicates the challenges of the thoracoscopic intrathoracic anastomosis. This model is intended to serve as a teaching tool during the introduction to, and development of, the skills required to perform a thoracoscopic intrathoracic anastomosis during an Ivor Lewis minimally invasive esophagectomy.

Methods:

The simulation model uses porcine tissue placed within an artificial hemithorax and covered with a synthetic skin. The model is draped to simulate a realistic operative setting, and ports are placed in standard surgical fashion. Dissection of the esophagus from the mediastinum is then performed, followed by the creation of an esophagogastric anastomosis. The effectiveness of the training model was evaluated using volunteer general and thoracic surgery residents at varying stages of surgical training. The quality of the anastomoses created were evaluated using both objective and subjective criteria, and successful anastomoses were tested for leaks using hydrostatic pressure.

Results:

Objective evaluation showed that successful completion of the anastomosis task increased with the number of attempts, with 100% of participants successfully completing an anastomosis by the final attempt. The time to completion of a successful anastomosis also improved across successive attempts. Moreover, objective measures also showed improvement over time based on the graded quality of the completed anastomosis.

Conclusion:

As surgical techniques continue to evolve, so must the means by which they are taught. This simulation model shows effectiveness in the training of general and thoracic surgery residents performing thoracoscopic intrathoracic anastomosis during the Ivor Lewis minimally invasive 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.
