Catheter-guided anvil insertion for circular stapler esophagojejunal anastomosis: a novel technique in laparoscopic total gastrectomy. Updates Surg 2024:10.1007/s13304-024-01753-2. [PMID: 38451410 DOI: 10.1007/s13304-024-01753-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 01/08/2024] [Indexed: 03/08/2024]
Abstract
OBJECTIVE This study evaluates feasibility, safety, and short-term outcomes of employing the catheter-guided stapler anvil insertion technique for esophagojejunal anastomosis using a circular stapler during laparoscopic total gastrectomy (LTG). MATERIALS AND METHODS From September 2021 to April 2023, the catheter-guided stapler anvil insertion technique was employed in 80 patients undergoing laparoscopic total gastrectomy (LTG) for esophagojejunal anastomosis. A modified D2 dissection, according to the en bloc technique, was performed in the patients. Subsequently, a longitudinal incision, approximately 2 cm in length, was made on the anterior wall of the esophagus, about 2 cm above the tumor. The transection line was pre-marked with blue dye along the esophagus's minor axis, and the tail of the anvil was capped with a 10-cm length of catheter (F14 d4.7 mm). The surgeon secures the head of anvil and carefully inserts it into the esophagus, ensuring that only a 5-cm segment of the catheter remains outside the esophagus. A linear cutter was employed to transect and seal the lower end of the esophagus. Subsequently, esophagojejunostomy was performed under laparoscopic guidance using a circular stapler. RESULTS Among patients undergoing esophagojejunal anastomosis with the new technique, postoperative complications included pneumonia or pleural effusion in 14 patients (17.5%), anastomotic stenosis in 3 patients (3.75%), abdominal infection in 2 patients (2.5%), and intestinal obstruction in 1 patient (1.25%). No instances of anastomotic leakage, anastomotic bleeding, or deaths were recorded. All patients experiencing complications improved with conservative treatment, without the need for secondary surgery. CONCLUSION The catheter-guided stapler anvil insertion technique is demonstrated to be a safe and effective method for esophagojejunostomy, potentially reducing the occurrence of anastomotic leakage.

[PMID: 37347097 PMCID: PMC10280111 DOI: 10.7602/jmis.2023.26.2.64] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/31/2023] [Accepted: 04/25/2023] [Indexed: 06/23/2023]
Abstract
Purpose In minimally invasive esophagectomy (MIE), it is important to reduce the rate of anastomotic leakage to ensure its safety. At our institute, the double-ligation method (DLM) has been introduced to insert and fix the anvil of the circular stapler for intracorporeal circular esophagojejunostomy in gastric surgery. We adopted this method for intrathoracic anastomosis (IA) in MIE. The aim of this study was to investigate the safety of IA with DLM in MIE. Methods In this study, 48 patients diagnosed with primary middle or lower third segment thoracic esophageal carcinoma with clinical stage I, II, III or IV disease were retrospectively evaluated. Postoperative outcomes were assessed. Results Among the 48 patients, 42 patients underwent laparo-thoracoscopic esophagectomy and IA using a circular stapler with the DLM. The average total operation time and thoracoscopic operation time were 433 and 229 minutes, respectively. The average purse-string suturing time was 4.7 minutes. The rates of anastomotic leakage and stenosis were 2.4% and 14.3%, respectively. The overall incidence of postoperative complications (Clavien-Dindo grade of ≥III) was 16.7%. The average postoperative stay was 16 days. Conclusion The procedure of IA using a circular stapler with the DLM in MIE was safe and provided a low rate of anastomotic leakage.

A novel method of anvil placement of circular stapler for esophagojejunostomy in laparoscopic total gastrectomy for gastric cancer: results of consecutive 200 cases. Surg Endosc 2023; 37:1021-1030. [PMID: 36097097 DOI: 10.1007/s00464-022-09566-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 08/14/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND Laparoscopic total gastrectomy for gastric cancer is still a demanding operation because of technical difficulties, especially of intracorporeal esophago-jejunal anastomosis. METHODS We introduced a newly designed method of anvil placement of circular stapling devices (CS) for laparoscopic esophagojejunostomy (EJS). A small incision was made on the anterior wall of the stomach, from which the anvil was inserted into the stomach and proceeded to the thoracic esophagus. Then, the abdominal esophagus was transected by a linear stapler, and the anvil into the esophagus was drawn back to the esophageal stump by pulling out the cotton tape pre-attached to the anvil. Intracorporeal EJS by Roux-en-Y reconstruction was performed by CS inserted into the abdominal cavity from the umbilical wound. RESULTS A total of consecutive 200 gastric cancer patients underwent laparoscopic total gastrectomy using this method. There was no operative mortality. Anastomotic complications occurred in 12 cases (6.0%): 9 cases of stenosis (4.5%) and 3 cases of bleedings (1.5%). Anastomotic leakage was not observed. As for non-anastomotic complications, there occurred 2 pulmonary complications (1.0%), 3 pancreatic leakages (1.5%), and 8 bowel obstructions due to internal hernia (4.0%). With a median follow-up period of 47.1 months, 5-year overall survival for assessable patients (n = 193) was 60.3% (95% CI 52.6-67.2). The total rate of peritoneal recurrence was 9.8%. CONCLUSION Our new method of anvil placement for laparoscopic EJS with CS is safe and feasible with favorable survival outcomes. It eliminates the need for suturing, and will promote the clinical application of laparoscopic total gastrectomy for gastric cancer. CLINICAL TRIALS UMIN000046119.

Hybrid esophagogastric tube anastomosis after minimally invasive McKeown esophagectomy to prevent stenosis in patients with esophageal cancer. Langenbecks Arch Surg 2023; 408:7. [PMID: 36597004 DOI: 10.1007/s00423-022-02743-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Accepted: 10/27/2022] [Indexed: 01/05/2023]
Abstract
PURPOSE The use of a small circular stapler has been reported to increase the incidence of benign anastomotic stenosis in reconstruction. In circular stapling anastomosis after esophagectomy, the anastomotic lumen is dependent on the size of the esophagus and the replacement organ. We developed a new and foolproof method to prevent stenosis in esophagogastric tube anastomosis for patients with esophageal cancer that is not dependent on operator skill. METHODS Seven patients with esophageal squamous cell carcinoma underwent minimally invasive McKeown esophagectomy in our hospital. Esophagogastric tube anastomosis was tried for all patients using the novel "hybrid esophagogastric tube anastomosis" technique. A 21-mm circular stapler was applied to perform an end-to-side anastomosis between the cervical esophagus and the posterior wall of the gastric tube. Then, a 30-mm linear stapler was positioned in the esophagogastric anastomosis formed by the 21-mm circular stapler with the anvil fork inserted into the esophagus and the cartridge fork inserted into the gastric tube. A supplementary side-to-side anastomosis of appropriately 15 mm was created. Afterward, the entry hole was closed with a linear stapler. RESULTS The hybrid esophagogastric tube anastomosis was successful in all seven patients receiving it between June 2020 and March 2022. No postoperative complications related to this anastomosis were observed in any of the patients. Five patients underwent follow-up gastrointestinal endoscopy at 6 months after esophagectomy. No patient had an anastomotic stenosis. CONCLUSIONS Hybrid esophagogastric tube anastomosis can be performed easily and safely and can reduce the complications associated with anastomosis.

Circular-stapled esophagogastrostomy using the keyhole procedure after radical esophagectomy for esophageal cancer. Esophagus 2023; 20:63-71. [PMID: 36042126 DOI: 10.1007/s10388-022-00949-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 08/19/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Anastomotic leakage of cervical esophagogastrostomy following radical esophagectomy for esophageal cancer has reduced over time; however, postoperative anastomotic stricture still occurs at a considerably high rate. We developed a novel method of circular-stapled esophagogastrostomy by employing the keyhole procedure, which uses a linear stapler to enlarge the anastomotic opening made with a circular stapler (CS). METHODS We retrospectively reviewed 70 patients with esophageal cancer who underwent transthoracic esophagectomy and reconstruction via cervical CS-mediated anastomosis with or without the keyhole procedure between 2018 and 2020. The primary outcome was postoperative anastomotic stricture incidence within 180 days after surgery. RESULTS Among 70 patients, 22 underwent the keyhole procedure (CS + K group) and the remaining did not (CS group). No differences were observed in patients' age, sex, body mass index, performance status, American Society of Anesthesiologists physical status, Charlson's comorbidity index, tumor histological type, tumor location, clinical stage, or preoperative treatment. A smaller stapler was used in the CS + K group (p < 0.001). Incidence of anastomotic stricture was significantly different (CS vs. CS + K, 18.8 vs. 0%, p = 0.049), especially when a 21 or 23 mm CS was used (CS vs. CS + K, 50.0 vs. 0%, p = 0.005). Univariate analysis confirmed that CS ≤ 23 without keyhole was a significant risk factor (p = 0.001). CONCLUSIONS The keyhole procedure could be a simple and useful alternative technique that reduces the risk of stricture formation in cervical esophagogastric anastomosis, especially when using the smaller-sized CS.

Preliminary evaluation of two-row versus three-row circular staplers for colorectal anastomosis after rectal resection: a single-center retrospective analysis. Int J Colorectal Dis 2022; 37:2501-2510. [PMID: 36385574 DOI: 10.1007/s00384-022-04283-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/09/2022] [Indexed: 11/18/2022]
Abstract
PURPOSE Circular staplers for colorectal anastomoses significantly ameliorated post-operative outcomes after rectal resection. The more recent three-row technology was conceived to improve anastomotic resistance and, thus, lower the incidence of anastomotic complications. The aim of this study was to evaluate potential advantages of three-row circular staplers (Three-CS) on anastomotic leakage (AL), stenosis (AS), and hemorrhage (AH) rates after rectal resection as compared to two-row circular staplers (Two-CS). METHODS All rectal resections for rectal cancer between 2016 and 2021 were retrospectively included. Patients were classified according to the circular stapler employed in Two-CS and Three-CS cohorts. AL, AS, and AH rates were compared between the two populations. Additionally, the prognostic role of the type of circular stapler on AL onset was evaluated. RESULTS Three-hundred and seventy-five patients underwent a rectal resection with an end-to-end anastomosis during the study period: 197 constituted the Two-CS group and 178 the Three-CS cohort. AL rate was 6.7%, significantly higher in the Two-CS group (19-9.6%) as compared to the Three-CS cohort (6-3.4%) (p = 0.01). No difference was noted in terms of AL severity. Although not statistically significant, a lower incidence rate of AL was evidenced even in the subset of patients with low rectal cancers (4.5% vs 12.5% in the two-row cohort; p = 0.33). At the multivariate analysis, Two-CS was a negative prognostic factor for AL onset (OR: 2.63; p = 0.03). No difference was noted between the two groups in terms of AS and AH. CONCLUSION Three-row CSs significantly decrease the rate of AL after rectal resection. Further multicenter controlled trials are still needed to confirm the advantages of three-row CSs on anastomotic complications.

Effect of the First Assistant on Anastomotic Leakage after Rectal Cancer Surgery with Double-Stapling Anastomosis: A Propensity Score Matching Analysis. Dig Surg 2022; 39:176-182. [PMID: 35882209 DOI: 10.1159/000525909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Accepted: 06/25/2022] [Indexed: 12/10/2022]
Abstract
INTRODUCTION Proper handling and firing of the circular stapler are important for secure anastomosis in rectal cancer surgery. This study aimed to investigate the association between the first assistant and anastomotic leakage (AL) after rectal cancer surgery with double-stapling anastomosis. METHODS Patients with primary rectal cancer who underwent low anterior resection with double-stapling anastomosis between January 2015 and September 2019 were included. Data on clinicopathological characteristics, including the first assistant's sex and experience level, were retrospectively reviewed, and the risk factors for AL were analyzed using propensity score matching analysis. RESULTS Among 758 rectal cancer surgeries, residents participated in 401 (52.9%) surgeries, and fellows participated in 357 (47.1%) surgeries as first assistants. After propensity score matching (n = 650), AL occurred in 5.4% (35/650). The first assistant's experience level (resident: 5.5% vs. fellow: 5.2%, p = 0.862) and sex (male: 5.4% vs. female: 4.9%, p = 0.849) were not associated with the occurrence of AL. Male sex in patients was the only significant predictive factor for AL (odds ratio = 2.804, 95% confidence interval 1.070-7.351, p = 0.036). DISCUSSION/CONCLUSION The first assistant's sex and experience level were not associated with AL after rectal cancer surgery with double-stapling anastomosis. These findings may justify resident participation in rectal cancer surgeries in which circular staplers are used.

Anastomosis oversewing technique to prevent leakage after oesophagectomy: a propensity score-matched analysis. Eur J Cardiothorac Surg 2022; 61:990-998. [PMID: 35325107 DOI: 10.1093/ejcts/ezab495] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 10/04/2021] [Accepted: 10/23/2021] [Indexed: 11/12/2022] Open
Abstract
OBJECTIVES Oesophagogastric anastomosis is a core part of oesophagectomy, and anastomotic leakage is among its main concerns. We used the oversewing technique to reinforce the anastomosis created with a circular stapler. This study investigated the use of oversewing to reduce the incidence of anastomotic leakage without increasing morbidity. METHODS This study enrolled 1734 patients who underwent oesophagectomy for oesophageal cancer between April 2012 and December 2019. Using propensity score-matched analysis, the clinical results of postoperative complications were compared between anastomotic-oversewn and -unsewn oesophagectomies. RESULTS Of the 1734 patients, 661 were included in the anastomotic-unsewn group and 661 in the anastomotic-oversewn group after propensity score matching. The clinical characteristics did not differ between the 2 groups, but the frequency of anastomotic leakage was significantly higher in the anastomotic-unsewn group than in the anastomotic-oversewn group (10.3% vs 4.7%, P < 0.001). Multivariable logistic analysis showed oversewn anastomosis and smoking history as the independent factors associated with anastomotic leakage (odds ratios, 0.399 and 2.383; P < 0.001 and P = 0.012, respectively). On the sub-group analysis, the relative risk for anastomotic leakage was significantly higher with unsewn than with oversewn anastomosis in patients <65 years old, those with American Association of Anesthesiologists score II, those who had middle segment oesophageal cancer and those who have undergone the McKeown approach and cervical anastomosis. CONCLUSIONS Anastomosis oversewing technique may be a practical method to reduce anastomotic leakage, especially in younger patients and those who have undergone the McKeown approach and cervical anastomosis.

Circular Stapler Method for Avoiding Stricture of Cervical Esophagogastric Anastomosis. J Gastrointest Surg 2022; 26:725-732. [PMID: 35138510 DOI: 10.1007/s11605-022-05266-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Accepted: 01/25/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND This study was performed to verify the superiority of a new "non-tensioning method" for avoiding stricture of the cervical esophagogastric anastomosis by circular stapling compared with the conventional method. METHODS In total, 395 consecutive patients who underwent McKeown esophagectomy with gastric conduit (GC) reconstruction were reviewed. A 4 cm-wide GC was created and pulled up at the cervical site through the retrosternal route. The esophagogastrostomy site of the GC was planned as far caudally as possible on the greater curvature side. In the conventional technique, the stapler was fired while pulling the GC to avoid tissue slack. In the non-tensioning technique, the stapler was fired through the natural thickness of the stomach wall. The length of the blind end was changed from 4 to 2 cm in the non-tensioning technique. Anastomotic leakage and stricture formation were compared between the two techniques, and adjustment was performed using propensity score matching. RESULTS The conventional group comprised 315 patients, and the non-tensioning group comprised 80 patients. Anastomotic leakage occurred in 22 (7%) and 2 (2.5%) patients, respectively (P = 0.134) [and in 9 (2.9%) and 2 (2.5%) patients, respectively, if leakage at the blind end was excluded]. Anastomotic stricture occurred in 92 (29.2%) and 3 (3.8%) patients, respectively (P < 0.001). The propensity score-matching analysis including 79 pairs of patients confirmed a lower stricture rate in the non-tensioning than conventional group (2.5% vs. 29.1%, P < 0.001). CONCLUSIONS The non-tensioning technique significantly reduced the incidence of anastomotic stricture compared with the conventional technique.

Abstract
Objective: To explore the differences of short-term outcomes and quality of life (QoL) for gastric cancer patients between totally laparoscopic total gastrectomy using an endoscopic linear stapler and laparoscopic-assisted total gastrectomy using a circular stapler. Methods: A retrospective cohort study was conducted. Clinicopathological data of patients with stage I to III gastric adenocarcinoma who underwent laparoscopic total gastrectomy from January 2017 to January 2020 were retrospectively collected. Those who were ≥80 years old, had serious complications that could affect the quality of life, underwent multi-organ resections, palliative surgery, emergency surgery due to gastrointestinal perforation, obstruction, bleeding, died or lost to follow-up within 1 year after surgery were excluded. A total of 130 patients were enrolled and divided into circular stapler group (CS group, 77 cases) and linear stapler group (LS group, 53 cases) according to the surgical method. The differences of age, gender, body mass index, number of comorbidities, history of abdominal surgery, ASA, tumor location, degree of differentiation, tumor length, tumor T stage, tumor N stage, tumor pathological stage and preoperative quality of life between the two groups were not statistically significant (all P>0.05). The observation indicators: (1) Surgery and postoperative conditions. (2) Postoperative complications: Any adverse conditions that require conservative treatment or surgical intervention after surgery were defined as postoperative complications, of which, complications occurring within 30 days after surgery were defined as early complications; complications occurring within 30 days to 1 year after surgery were defined as late complications. (3) Postoperative quality of life was assessed by the quality of life core scale (QLQ-C30) and gastric cancer specific module scale (QLQ-STO22). The higher the scores of functional scales and global health status, the better the corresponding quality of life. The higher the scores of symptoms scales, the worse the corresponding quality of life. Results: (1) Surgery and postoperative conditions: Compared with the CS group, the LS group presented less intraoperative blood loss [50.0 (50.0-100.0) ml vs. 100.0 (100.0-100.0) ml, Z=-3.111, P=0.002] and earlier time to flatus [(3.1±0.8) days vs. (3.5±1.1) days, t=-2.490, P=0.014]. However, there were no statistically significant differences between two groups of patients in terms of operation time, time to start a liquid diet and postoperative hospital stay (all P>0.05). (2) Postoperative complications: The early complication rates of the CS group and the LS group were 22.1% (17/77) and 18.9% (10/53), respectively, while the late complication rate were 18.2% (14/77) and 15.1% (8/53), respectively, whose differences were not statistically significant (all P>0.05). (3) Postoperative quality of life: After 1-year follow-up, 7 (5.4%) patients were lost, including 5 in CS group and 2 in LS group. One year after operation, the QLQ-C30 scale showed that the score of financial difficulty of the LS group was significantly higher than that of the CS group [33.3 (0 to 33.3) vs.0 (0 to 33.3), Z=-1.972, P=0.049] with statistically significant difference, and there were no statistically significant differences in the scores of other functional fields and symptom fields between the two groups (all P>0.05). The QLQ-STO22 scale showed that the scores of dysphagia [0 (0 to 5.6) vs. 0 (0 to 11.1), Z=-2.094, P=0.036] and eating restriction were significantly lower [0 (0 to 4.2) vs. 0 (0 to 8.3), Z=-2.011, P=0.044] in patients of the LS group than those of the CS group. There were no significant differences in scores of other symptoms between two groups (all P>0.05). Conclusions: Compared with the circular stapler, the esophagojejunostomy with linear stapler for gastric cancer patients can reduce intraoperative blood loss, shorten the time to flatus after operation, alleviate the symptoms of dysphagia and eating restriction but increase the economic burden to a certain degree.

Abstract
Background Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been established as a leading treatment of obesity. Surgical site infections (SSIs) remain the most common complication. Objective To compare the incidence of SSIs before and after the implementation of our technique. Methods Our intraoperative technique limits enteric contact with the abdominal wall through a wound protector at the end-to-end anastomosis stapler port site, with enteric retrieval with a specimen bag followed by betadine irrigation. We analyzed our SSIs outcomes before and after implementation of our technique in all RYGB and laparoscopic sleeve-to-bypass conversions at our institution performed by two providers between January 1, 2009 to December 31, 2011 and January 1, 2019 to December 31, 2021. We compared patient age, sex, body mass index, American Society of Anesthesiologists class; and comorbidities including hypertension, diabetes, and hyperlipidemia. The χ2, Fischer exact, Wilcoxon Rank Sum tests, and multivariate analysis were performed. Results Four hundred twenty-nine patients underwent LRYGB and sleeve-to-bypass conversion during the two study periods. Group 1 (162 patients, 37.76%) all underwent RYGB. Group 2 (267 patients, 62.24%) of whom 199 underwent RYGB and 68 underwent a laparoscopic sleeve-to-bypass conversion. The SSI rate was 9.26% in Group 1 and 2.62% in Group 2 (p = 0.002514). Statistical significance was also noted for operating room time (137 min vs 123 min, p = 0.02) and hospital length of stay (2 - 3 interquartile range vs 1 - 2 interquartile range, p = 0.04). Conclusion We propose a safe, reproducible technique that significantly reduces SSI rates during LRYGB.

Outcomes associated with the use of a new powered circular stapler for left-sided colorectal reconstructions: a propensity score matching-adjusted indirect comparison with manual circular staplers. Surg Endosc 2021; 36:2541-2553. [PMID: 34031743 PMCID: PMC8921098 DOI: 10.1007/s00464-021-08542-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Accepted: 05/04/2021] [Indexed: 12/17/2022]
Abstract
Background This was a retrospective, matching-adjusted indirect comparison of clinical outcomes between patients from a single-arm trial of the ECHELON CIRCULAR™ Powered Stapler (ECP) and those from a historical cohort of patients who underwent left-sided colorectal resection using conventional manual circular staplers, extracted from the Premier Healthcare Database. Methods Patients in the ECP trial cohort were propensity score matched to those in the historical cohort through nearest neighbor matching. Outcomes included 30-day readmission rates; length of stay (LOS) for the index admission; rates of anastomotic leak, pelvic abscess, ileus/small bowel obstruction, infection, bleeding, and stoma creation. Results The study included 168 patients in the ECP trial cohort and 4544 patients in the historical cohort; 165 ECP trial patients were matched to 1348 historical cohort patients. After matching, conversions were more prevalent in the historical cohort than the ECP trial cohort (4.2% ECP vs. 10.2% historical, p = 0.001). Relative to the historical cohort, the ECP trial cohort had statistically significant lower rates of 30-day inpatient readmission (6.1% vs. 10.8%, p = 0.019), anastomotic leak (1.8% vs. 6.9%, p < 0.001), ileus/small bowel obstruction (4.8% vs. 14.7%, p < 0.001), infection (1.8% vs. 5.7%, p = 0.001), and bleeding (1.8% vs. 9.2%, p < 0.001) during the index admission or within 30 days thereafter. No statistically significant differences in rates of pelvic abscess, stoma creation, or LOS were found between the two cohorts. Three sensitivity analyses to address the difference in conversion rates yielded largely consistent results, with loss of statistical significance for inpatient admission in some cases. This study is limited by its potential for differences in unmeasurable factors between the ECP trial and historical cohorts. Conclusions In this study, the ECP trial cohort had lower incidence proportions of several surgical complications as compared with the historical cohort. Further controlled prospective clinical studies are needed to confirm the validity of this finding.

Abstract
Intracorporeal classic gastrointestinal anastomosis using circular stapler in totally laparoscopic gastrectomy (TLG) for gastric cancer requires intracorporeal anvil placement and suitable access for introduction of the circular stapler to the abdominal cavity without gas leak. The novel techniques for anvil placement have been updated, but there is no progress for proper access for circular stapler. In the study, intracorporeal circular-stapled gastrointestinal anastomosis were successfully accomplished using a novel device of sealed cap access with a central hole (WLB-60/70-60/100, Wuhan Widerep Medical Instrument Co.,Ltd, China) customized to the incision protection retractor for the simple and accessible introduction of the circular stapler and anvil under the optimal maintenance of pneumoperitoneum pressure in TLG. In these 3 cases, there was no gas leakage and the pneumoperitoneum was well maintained when performing the gastrointestinal anastomosis, and there was no transition to laparotomy or other anastomosis techniques. The result suggests that the sealed cap access could be a novel choice for introduction of the circular stapler to the abdominal cavity in order to obtain laparoscopic circular-stapled gastroin-testinal anastomosis in TLG.

Assessment of a circular powered stapler for creation of anastomosis in left-sided colorectal surgery: A prospective cohort study. Int J Surg 2020; 84:140-146. [PMID: 33176211 DOI: 10.1016/j.ijsu.2020.11.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 10/31/2020] [Accepted: 11/03/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Circular staplers perform a critical function for creation of anastomoses in colorectal surgeries. Powered stapling systems allow for reduced force required by surgeons to fire the device and may provide advantages for creating a secure anastomosis. The objective of this study was to evaluate the clinical performance of a novel circular powered stapler in a post-market setting, during left-sided colectomy procedures. MATERIALS AND METHODS Consecutive subjects underwent left-sided colorectal resections that included anastomosis performed with the ECHELON CIRCULAR™ Powered Stapler (ECP). The primary endpoint was the frequency in which a stapler performance issue was observed. Secondary endpoints included evaluation of ease of use of the device via a surgeon satisfaction questionnaire, and monitoring/recording of procedure-related adverse events (AEs). RESULTS A total of 168 anastomoses were performed with the ECP. Surgical approaches included robotic-assisted (n = 74, 44.0%), laparoscopic (n = 71, 42.3%), open (n = 20, 11.9%), and hand-assisted minimally invasive (n = 3, 1.8%) procedures. There were 22 occurrences of device performance issues in 20 (11.9%) subjects during surgery. No positive intraoperative leak tests were observed, and only 1 issue was related to a procedure-related AE or surgical complication, which was an instance of incomplete surgical donut necessitating re-anastomosis. Postoperative anastomotic leaks were experienced in 4 (2.4%) subjects. Clavien-Dindo classification of all AEs indicated that 92.0% were Grades I or II. Participating surgeons rated the ECP as easier to use compared to previously used manual circular staplers in 85.7% of procedures. CONCLUSION The circular powered stapler exhibited few clinically relevant performance issues, an overall favorable safety profile, and ease of use for creation of left-sided colon anastomoses.

Comparison of greater curvature and lesser curvature circular-stapled esophagogastrostomy after esophagectomy in patients with esophageal cancer: a prospective randomized controlled trial. Surg Today 2020; 51:575-581. [PMID: 32974752 DOI: 10.1007/s00595-020-02147-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Accepted: 08/11/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Using a circular stapler to create an anastomosis for esophagogastrostomy after esophagectomy is well accepted; however, it remains uncertain if the greater curvature (GC) or lesser curvature (LC) of the gastric conduit is better for the anastomosis. We conducted this prospective study to compare the integrity of esophagogastrostomy between the esophagus and the GC or LC side of the gastric conduit. METHODS The subjects of this study were 70 patients who underwent esophagectomy and were randomized to a "GC" group and an "LC" group (n = 35 each). The primary and secondary end points were anastomotic leakage (AL) and anastomotic stricture (AS), respectively. RESULTS The overall AL rate was 22.1%, without a significant difference between the groups. Stump leakage developed in eight of nine patients in the GC group, whereas leakage developed at the esophagogastric anastomosis in five of six patients in the LC group. The rate of stump leakage was significantly higher than that of esophagogastric AL in the GC group. The overall AS rate was 4.4%, with a significant difference between the groups (0% in the GC group vs. 9.1% in the LC group). CONCLUSIONS AL rates were comparable in the two groups, but the sites of leakage were significantly different.

Intracorporeal esophagojejunostomy using a linear stapler in laparoscopic total gastrectomy: comparison with circular stapling technique. BMC Surg 2020; 20:100. [PMID: 32398072 PMCID: PMC7218545 DOI: 10.1186/s12893-020-00746-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Accepted: 04/15/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Laparoscopic total gastrectomy for gastric cancer is feasible but less commonly performed compared to laparoscopic distal gastrectomy due to technical difficulties such as reconstruction. There is no standard esophagojejunal anastomosis technique in laparoscopic total gastrectomy due to a lack of evidence. METHODS We retrospectively analyzed data from 213 patients with gastric cancer who underwent laparoscopic total gastrectomy from October 2012 to December 2016. Of these, 109 and 104 patients underwent esophagojejunostomy with linear and circular stapling, respectively. We compared short-term postoperative outcomes, including surgical complications and anastomosis costs between both groups. RESULTS The mean operation time in the linear stapler group was longer than the circular stapler group (Linear stapler, 235.3 ± 57.9 vs. Circular stapler, 217.1 ± 55.8 min; P = 0.021); however, D2 lymph node dissection was performed more in the linear stapler group (Linear stapler, 36.7% vs. Circular stapler, 23.1%; P = 0.030). There were two anastomosis leakages in each group (Linear stapler, 1.8% vs. Circular stapler, 1.9%; P > 0.999). Anastomosis stenosis only occurred in the circular stapler group (Linear stapler, 0% vs. Circular stapler, 7.7%; P = 0.003). Although the linear stapling technique used more stapler cartridges (Linear stapler, 7.6 ± 1.1 vs. Circular stapler, 4.8 ± 0.9; P < 0.001), costs related to anastomosis were lower in the linear stapler group (Linear stapler, 1,904,679 ± 342,116 vs. Circular stapler, 2,246,150 ± 427,136KRW; P < 0.001). CONCLUSIONS Esophagojejunostomy with the linear stapling technique reduces anastomosis stenosis in laparoscopic total gastrectomy. It can be recommended as a safe and more cost-effective method for esophagojejunal anastomosis.

Abstract
To compare circular stapler (CS) with linear stapler (LS) in a meta-analysis concerning operative time, anastomotic leaks, wound infections, strictures, and length of stay. Pubmed, Medline, and Scopus were searched for articles published since 2006. Four hundred and five articles were assessed, and 13 articles of which only one was a randomized controlled trial were included in all 49,331 patients from different regions of the world. The pooled analysis shows that operative time was shorter in LS than in CS (weighted mean difference 36.2 min; 95% CI 34.7-37.6.; p < 0.0001). No difference was seen concerning leaks or strictures. The relative risk (RR) of leakage after LS was 80% of the risk after CS; however, the 95% confidence interval (CI) showed overlap (0.58-1.11). The RR of anastomotic stricture after LS was 74% of the risk after CS; however, 95% CI (0.52-1.05) showed overlap. Wound infections were less common after LS than after CS; RR was 27% (95% CI 0.21-0.33). Length of stay (LOS) was 0.65 days shorter after LS than after CS (95% CI 0.51-0.78). LS compared with CS results in shorter operative time, less wound infections, and shorter length of stay, but no difference was seen concerning risks of leaks or strictures.

Linear or circular stapler? A propensity score-matched, multicenter analysis of intracorporeal esophagojejunostomy following totally laparoscopic total gastrectomy. Surg Endosc 2019; 34:5265-5273. [PMID: 31820152 DOI: 10.1007/s00464-019-07313-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Accepted: 11/28/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Presently, there is no consensus as to what procedure of intracorporeal esophagojejunostomy (EJS) in totally laparoscopic total gastrectomy (TLTG) is best to reduce postoperative complications. The aim of this study was to demonstrate the superiority of linear stapled reconstruction in terms of anastomotic-related complications for EJS in TLTG. METHODS We collected data on 829 consecutive gastric cancer patients who underwent TLTG reconstructed by the Roux-en-Y method with radical lymphadenectomy between January 2010 and December 2016 in 13 hospitals. The patients were divided into two groups according to reconstruction method and matched by propensity score. Postoperative EJS-related complications were compared between the linear stapler (LS) and the circular stapler (CS) groups. RESULTS After matching, data from 196 patients in each group were analyzed. The overall incidence of EJS-related complications was significantly lower in the LS group than in the CS group (4.1% vs. 11.7%, p = 0.008). The incidence of EJS anastomotic stenosis during the first year after surgery was significantly lower in the LS group than in the CS group (1.5% vs. 7.1%, p = 0.011). The incidence of EJS bleeding did not differ significantly between the groups, although no bleeding was observed in the LS group (0% vs. 2.0%, p = 0.123). The incidence of EJS leakage did not differ significantly between the groups (2.6% vs. 3.6%, p = 0.771). CONCLUSION The use of linear stapled reconstruction is safer than the use of circular stapled reconstruction for intracorporeal EJS in TLTG because of its lower risks of stenosis.

21- versus 25-mm Circular Staplers for Cervical Anastomosis: A Propensity-Matched Study. J Surg Res 2019; 246:427-434. [PMID: 31699537 DOI: 10.1016/j.jss.2019.09.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Revised: 07/28/2019] [Accepted: 09/13/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND The use of a small circular stapler (CS) has been reported to increase the incidence of benign anastomotic stricture of the intrathoracic anastomosis after esophagectomy, but no study has evaluated the effects of the CS size on cervical esophagogastrostomy. Based on a propensity-matched comparison, the present study was designed to determine whether the perioperative outcomes differ between 21- and 25-mm CSs after minimally invasive esophagectomy with cervical anastomosis. METHODS From January 2015 to December 2017, 162 patients who received CS cervical esophagogastric anastomosis after minimally invasive esophagectomy for esophageal cancer were identified from our surgical database. A propensity-matched analysis was used to compare the outcomes between the 21- and 25-mm CS groups. Endpoints included anastomotic leak, dysphagia, reflux, stricture, and other major postoperative outcomes within 6 postoperative months. RESULTS There were 69 and 93 patients in the 21- and 25-mm CS groups, respectively. Propensity matching produced 57 patients in each group. The two groups were not remarkably different in benign anastomotic stricture rate (P = 0.528). All strictures were resolved by balloon dilatation. The 25-mm CS group had a significantly longer operative time in cervical anastomosis than the 21-mm group (P = 0.005). No statistically significant differences in anastomotic leak rates, dysphagia scores, reflux scores, or other postoperative complications were noted between the two groups. CONCLUSIONS The use of a 21-mm CS in minimally invasive esophagectomy with cervical esophagogastric anastomosis did not result in greater anastomotic stricture as compared with a 25-mm CS. The 21-mm CS was associated with a significantly shorter operative time.

Abstract
BACKGROUND While there are various techniques to create the gastrojejunostomy during a laparoscopic Roux-en-Y gastric bypass (LRYGB), many surgeons prefer using a circular stapler. One drawback of this method, however, is the higher incidence of surgical site infections (SSIs). To investigate the effect of a dual ring wound protector on SSIs during LRYGB. METHODS In April 2016, our bariatric surgical group implemented an intervention whereby a dual ring wound protector in conjunction with a conical EEA stapler introducer was used when creating the gastrojejunostomy. SSIs from pre- and post-intervention were compared using Fisher's exact test. Only LRYGBs performed with a circular stapler were included in our analysis. Student's t test and χ2 were used to compare pre- and post-intervention groups with respect to demographics and co-morbidities. RESULTS Between April 2015 and January 31st, 2017, our surgeons performed 158 LRYGBs using a circular stapler for the gastrojejunostomy. There were 84 patients (53%) in the pre-intervention group and 74 (47%) in the post-intervention group. The pre- and post-intervention groups were not statistically different. The SSI rate for the pre-intervention group was 9.5% while the SSI rate was 1.35% in the post-intervention group (p = 0.0371). The use of a dual ring wound protector for LRYGBs with circular stapled gastrojejunostomy was associated with an 86% relative risk reduction in SSIs. CONCLUSION Using a dual ring wound protector in conjunction with a conical EEA introducer for LRYGBs with circular stapled gastrojejunostomy significantly decreased SSIs.

Abstract
Purpose Although Roux-en-Y (R-Y) reconstruction after distal gastrectomy has several advantages, such as prevention of bile reflux into the remnant stomach, it is rarely used because of the technical difficulty. This prospective randomized clinical trial aimed to show the efficacy of a novel method of R-Y reconstruction involving the use of 2 circular staplers by comparing this novel method to Billroth-I (B-I) reconstruction. Materials and Methods A total of 118 patients were randomly allocated into the R-Y (59 patients) and B-I reconstruction (59 patients) groups. R-Y anastomosis was performed using two circular staplers and no hand sewing. The primary end-point of this clinical trial was the reflux of bile into the remnant stomach evaluated using endoscopic and histological findings at 6 months after surgery. Results No significant differences in clinicopathological findings were observed between the 2 groups. Although anastomosis time was significantly longer for the patients of the R-Y group (P<0.001), no difference was detected between the 2 groups in terms of the total surgery duration (P=0.112). Endoscopic findings showed a significant reduction of bile reflux in the remnant stomach in the R-Y group (P<0.001), and the histological findings showed that reflux gastritis was more significant in the B-I group than in the R-Y group (P=0.026). Conclusions The results of this randomized controlled clinical trial showed that compared with B-I reconstruction, R-Y reconstruction using circular staplers is a safe and feasible procedure. This clinical trial study was registered at www.ClinicalTrials.gov (registration No. NCT01142271).

Linear compared to circular stapler anastomosis in laparoscopic Roux-en-Y gastric bypass leads to comparable weight loss with fewer complications: a matched pair study. Langenbecks Arch Surg 2016; 401:307-13.

Abstract
OBJECTIVE In the course of laparoscopic Roux-en-Y gastric bypass (LRYGB), a tight gastroenterostomy (GE) may lead to higher weight loss but possibly to an increase of local complications such as strictures and ulcers. Different operative techniques for Roux-en-Y reconstruction may also influence the rate of internal hernias, a typical late complication of LRYGB. The objective of this study was to compare weight loss, rates of strictures, internal hernias, and ulcerations of linear versus circular stapler anastomosis. METHODS Retrospective analysis of prospectively collected data in a 3:1-matched pair study. A total of 228 patients with a minimal follow-up of 2 years were matched according to BMI at baseline, age, and gender. The follow-up rate was 100 % at 1 and 2 years postoperatively; the mean follow-up time was 3.8 ± 1.63 years. In group C (circular), 57 patients were operated with a 25-mm circular stapler technique (average BMI 44.7 ± 5.18 kg/m(2), age 44.1 ± 10.8 years, 80.7 % female). In group L (linear), 171 patients were operated using a linear stapler (approximately 30 mm, average BMI 43.8 ± 5.24 kg/m(2), age 43.7 ± 12.5 years, 70.8 % female). A propensity score matching and a logrank test were used for statistical analysis. RESULTS The average excessive BMI loss (EBMIL) after 1 year was not statistically different (70.6 ± 20.2 % in group C vs 72.5 ± 20.4 % in group L) as well as after 2 years (71.6 ± 22.5 % in group C vs 74.6 ± 19.6 % in group L). The average operation time was 155 ± 53 min in group C and 109 ± 57 min in group L (p = 0.0001). In group L, patients had significantly lower overall stricture rates at the GE compared to group C (0 [0 %] vs. 4 [7 %], p = 0.0004), a lower rate and severity of internal hernias (10 [5.8 %] vs. 7 [12.3 %] p = 0.466), and equal local ulcerations rates (3 [1.8 %] vs. 1 [1.8 %] p = 0.912). CONCLUSION Linear stapler anastomosis in LRYGB compared to circular anastomosis leads to equal weight loss and less strictures. The lower rate of internal hernias in linear stapler anastomosis was not significantly different.

Abstract
The totally laparoscopic total gastrectomy (TLTG) for gastric cancer has not gained widespread acceptance due to its technical difficulties, especially with the intracorporeal esophagojejunostomy (IEJS). Various modified procedures for the IEJS have been devised, but an optimal method has not yet been standardized. A total of 32 consecutive patients (23 men and 9 women) underwent TLTGs for gastric cancer, between December of 2009 and December of 2014 at the Iwate Medical University Hospital, and were enrolled in this study. Here, we report our institution's experience with TLTGs, with changes in the IEJS. The study participants had a mean age of 66.8 years and a body mass index of 22.8 kg/m2. The mean operation time and blood loss were 356.1 min and 61.2 mL, respectively. According to the IEJS, there were 6 circular stapler (CS) (single and double stapling techniques) and 26 linear stapler (LS) (overlap technique and functional end-to-end anastomosis) procedures performed. Two patients, who had undergone IEJS by double stapling technique, developed anastomotic stenosis and required endoscopic balloon dilatations of the anastomotic sites. Therefore, we changed to LS to secure the abundant anastomotic diameter. In our institute, some problematic complications in the IEJS procedure occurred at the introduction of the TLTG. We have overcome these complications by changing and standardizing the IEJS techniques, and by cultivating the laparoscopic techniques.

Delayed Gastric Emptying After Stapled Versus Hand-Sewn Anastomosis of Duodenojejunostomy in Pylorus-Preserving Pancreaticoduodenectomy: a Randomized Controlled trial. J Gastrointest Surg 2016; 20:595-603.

Abstract
BACKGROUND A retrospective analysis indicated that the incidence of delayed gastric emptying (DGE) was less after using a circular stapler (CS) for duodenojejunostomy than that after hand-sewn (HS) anastomosis in pylorus-preserving pancreaticoduodenectomy (PpPD). This randomized clinical trial compared the incidence of DGE postoperative after CS duodenojejunostomy with that of conventional HS anastomosis in PpPD. METHODS We randomly assigned 101 patients (age 20-80) undergoing PpPD to receive CS duodenojejunostomy (group CS, n = 50) or HS duodenojejunostomy (group HS, n = 51) in two Japanese cancer center hospitals between 2011 and 2013. The patients were stratified by institution and size of the main pancreatic duct (<3 or ≥3 mm). The primary endpoint was the incidence of grade B or C DGE according to the international definition with a non-inferiority margin of 5 %. This trial is registered with University hospital Medical Information Network (UMIN) Center: UMIN000005463. RESULTS Per-protocol analysis of data on 95 patients showed that grade B or C DGE was found in 4 (8.9 %) of 45 patients who underwent CS anastomosis and in 8 (16 %) of 50 patients who underwent HS anastomosis (P = 0.015). There were no differences in the overall incidence of DGE (P = 0.98), passage of the contrast medium through the anastomosis (P = 0.55), or hospital stays (P = 0.22). CONCLUSIONS CS duodenojejunostomy is not inferior to HS anastomosis with respect to the incidence of clinically significant DGE, justifying its use as treatment option.

[PMID: 26643298 DOI: 10.1007/s11605-015-3039-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2015] [Accepted: 11/23/2015] [Indexed: 01/31/2023]
Abstract
BACKGROUND Nowadays, laparoscopic abdominoperineal resection (LAPR) not only has the same oncologic safety of open surgery and but also has the common advantages of laparoscopic surgery. However, given the difficulty in operation and long operative time, laparoscopic extraperitoneal colostomy construction is rarely practiced and reported. In this study, we describe technique of extraperitoneal colostomy using circular stapler following LAPR and demonstrate its efficacy and safety. METHODS This is a retrospective analysis of prospectively maintained data of 42 patients who underwent LAPR with circular stapler-assisted extraperitoneal colostomy in our department between July 2011 and June 2014. RESULTS The mean time for extraperitoneal colostomy construction was 25 min (18-33 min). The mean operative time, estimated blood loss, postoperative gastrointestinal function recovery time, and duration of postoperative hospital stay were 160 min (115-225 min), 45 ml (10-250 ml), 33 h (26-45 h), and 8.6 days (6-13 days), respectively; 4.8 % of the patients had postoperative short-term complications. There were no stenosis, prolapse, and parastomal hernia observed in follow-up period. At 6 months after operation, 26 patients (62 %) claimed to be satisfied with their postoperative stool habits, 29 patients (69 %) had sensation to defecate per stoma, and 11 (26.2 %) patients had the ability to defer defecation for solid or liquid stool per stoma. CONCLUSION Circular stapler-assisted extraperitoneal colostomy is an easy, effective, and safe technique following LAPR and appears to minimize the occurrence of stomal complications and improve the quality of life for patients.

Abstract
BACKGROUND A higher incidence of gastrojejunal (GJ) anastomotic strictures has been reported following laparoscopic gastric bypass (LRYGB) with the 21 mm compared to 25 mm circular stapler. We hypothesized that the rate of stricture formation is affected by route of anvil insertion and its position relative to the gastric pouch staple line [trans-gastric above staple line (trans-gastric) vs. trans-oral through staple line (trans-oral)] following LRYGB. METHODS Retrospective review of consecutive patients who underwent LRYGB with circular stapled GJ studied in four groups: trans-gastric-21 mm, trans-gastric-25 mm, trans-oral-21 mm, and trans-oral-25 mm. Primary outcome studied was GJ stricture; secondary outcomes were results with endoscopic therapy and weight loss at 12 months. Predictors studied were age, gender, body mass index (BMI), comorbidities, and operative technical factors including anvil size and insertion route. Regression analyses were performed to identify predictors of GJ stricture. RESULTS Eight hundred seventy-six patients underwent LRYGB. Seventy-six (8.7 %) developed a GJ stricture. The highest stricture rate occurred in the trans-gastric-21 mm group (17 %, p < .01 for all comparisons). Stricture rates were similar for trans-gastric-25 mm (8.4 %), trans-oral-21 mm (5.2 %), and trans-oral-25 mm (1.6 %) groups. Independent predictors of stricture were: trans-gastric-21 mm (OR 10.9, 95%CI 1.4-85.1; p = .022) and age (OR 0.97, 95%CI 0.95-0.99; p = .002). Endoscopic dilation relieved symptoms in all patients. There was no difference in %EWL at 12 months in patients with and without a stricture. CONCLUSIONS We conclude that the trans-oral-21 mm anvil is associated with a low stricture rate. With the advantage of smaller abdominal wall wound, trans-oral-21 mm may be the preferred size and route of anvil insertion.

Abstract
OBJECTIVES Oesophagectomy with gastric pull-up is the most common surgical procedure for oesophageal cancer. Pyloroplasty may be performed to facilitate stomach emptying, but its role is still controversial. When laparoscopic mobilization of the stomach is performed, conventional extramucosal pyloroplasty may be difficult to carry out; therefore, we describe a new technique for mechanical pyloric disruption. METHODS We conceived the laparoscopic longitudinal extramucosal partial section of the anterior pyloric wall using a circular stapler. We performed it in 6 patients undergoing oesophagectomy for cancer, with the laparoscopic abdominal step before thoracotomy. RESULTS The procedure was easy and safe and without intraoperative complications in all patients. Postoperative video-oesophagogram showed regular anastomosis and graft emptying. CONCLUSIONS Our preliminary experience has led us to conclude that circular stapler longitudinal extramucosal pyloroplasty is an easy, safe and quick procedure that can be performed in laparoscopic surgery. Moreover, it seems to ensure a regular emptying of the graft as standard pyloroplasty does.

Comparison between circular- and linear-stapled gastrojejunostomy in laparoscopic Roux-en-Y gastric bypass--a cohort from the Scandinavian Obesity Registry. Surg Obes Relat Dis 2015; 11:1233-6. [PMID: 25979205 DOI: 10.1016/j.soard.2015.03.010] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2014] [Revised: 03/17/2015] [Accepted: 03/18/2015] [Indexed: 12/19/2022]
Abstract
BACKGROUND Although laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common bariatric procedure worldwide, no consensus on the optimal technique for the gastrojejunostomy (GJ) has been reached. Circular stapling (CS) immediately results in a GJ of standardized width, whereas linear stapling (LS) requires a technically challenging closure of the stapler defect. The aim was to study differences in outcomes between CS and LS. SETTING Nationwide Swedish cohort. METHODS The Scandinavian Obesity Registry (SOReg) included prospective data from 34,284 primary LRYGB patients operated on in 2007-2013. We studied operative time, length of hospital stay, postoperative complications, and percent excess body mass index loss (%EBMIL) after 1 year. Outcomes were assessed through multivariate analysis adjusting for gender, age, preoperative body mass index (BMI), and diabetes. RESULTS Preoperatively the groups were similar (40.9 yr, BMI 42.4 kg/m(2), 76% female). For CS and LS, operative time and hospital stay were 114 and 73 minutes (P<.001) and 4.6 and 2.0 days (P<.001), respectively. Using LS as a reference, adjusted odds ratio (OR) for CS patients to have anastomotic leakage was 2.8 (95% CI 1.5-5.0), postoperative hemorrhage 1.9 (95% CI 1.2-2.9), wound complication 9.7 (95% CI 6.8-13.9), and marginal ulcer 3.1 (95% CI 1.8-5.3). The %EBMIL at 1 year was 80% for both techniques and 31% of total weight was lost. Follow-up rate at 6 weeks and 1 year was 96% and 73%, respectively. CONCLUSION CS was found to be associated with disadvantages regarding operative time, hospital stay, and postoperative complications compared with LS.

Hand-Sewn Versus Stapled Esophagogastric Anastomosis in the Neck: A Systematic Review and Meta-analysis of Randomized Controlled Trials. Indian J Surg 2015; 77:133-40. [PMID: 26139968 PMCID: PMC4484531 DOI: 10.1007/s12262-013-0984-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2013] [Accepted: 09/24/2013] [Indexed: 01/25/2023] Open
Abstract
The application of cervical esophagogastric anastomoses was of great concern. However, between circular stapler (CS) and hand-sewn (HS) methods with anastomosis in the neck, which one has better postoperative effects still puzzles surgeons. This study aims to systematically evaluate the effectiveness, security, practicality, and applicability of CS compared with the HS method for the esophagogastric anastomosis after esophageal resection. A systematic literature search, as well as other additional resources, was performed which was completed in January 2013. The relevant randomized controlled trials (RCTs) about the surgical technique for esophageal resection were included. Trial data was reviewed and extracted independently by two reviewers. The quality of the included studies was assessed by the recommended standards basing on Cochrane handbook 5.1.0, and the data was analyzed via RevMan 5 software (version 5.2.0). Nine studies with 870 patients were included. The results showed that in comparing HS to CS methods with cervical anastomosis, no significant differences were found in the risk of developing anastomotic leakages (relative risk (RR) = 1.30, 95 % confidence intervals (CI) 0.87-1.92, p = 0.20), as well as the anastomosis stricture (RR = 0.97, 95 % CI 0.47-1.99, p = 0.93), postoperative mortality (RR = 0.83, 95 % CI 0.43-1.58, p = 0.57), blood loss (mean difference (MD) = 39.68; 95 % CI -6.97, 86.33; p = 0.10) and operative time (MD = 18.05; 95 % CI -3.22, 39.33; p = 0.10). However, the results also illustrated that the CS methods with cervical anastomosis might be less time-consuming and have shorter hospital stay and higher costs. Based upon this meta-analysis, there were no differences in the postoperative outcomes between HS and CS techniques. And the ideal technique of cervical esophagogastric anastomosis following esophagectomy remains under controversy.

Abstract
The double-stapling technique using a circular stapler (CS) to create an end-to-end anastomosis is currently used widely in laparoscopic-assisted rectal surgery. However, a high rate of anastomotic failure has been reported. We report new side-to-side anastomosis creation using a CS, the so-called circular side stapling technique (CST). After excising the rectum at the oral and anal sides of the tumor with a linear stapler, a side-to-side colorectal anastomosis was made on the anterior wall of the rectosigmoid colon and the anterior or posterior wall of the rectum with a CS. Between 2012 and 2013, we recorded 30 serial cases of rectal-sigmoid or rectal cancer that were treated with laparoscopic-assisted surgeries using this method. In the 30 cases, the mean age was 68 ± 12 years, operating time was 288 ± 80 minutes, and blood loss was 66 ± 67 mL. None of the patients suffered from anastomosis leakage or postoperative anastomotic bleeding, and none complained of their stool habits. Three months after the last surgery in this cohort, no anastomosis strictures were reported. Based on these results, we propose an alternative method of side-to-side anastomosis for low anterior resection by using a CS to prevent staple overlap. Our experience indicates that the CST is easy and safe. Therefore, this method is a useful alternative to the current method used in laparoscopic surgery.

Double circular stapler technique for bowel resection in rectosigmoid endometriosis. J Minim Invasive Gynecol 2013; 21:136-41.

Abstract
To reduce bladder function impairment and avert the serious complications of anastomotic leakage after segmental rectosigmoidectomy and to minimize the persistence of endometriotic lesions associated with discoid resection, we used the double circular stapling (DCS) technique. This technique enables excision of bowel endometriosis nodules larger than those that can be removed with the single-load technique of the circular stapler. Of 120 patients who underwent surgery to treat bowel endometriosis, intestinal shaving was performed in 24, discoid resection with single circular stapling in 40, and rectosigmoidectomy in 55. Eleven patients (9.2%) underwent the DCS technique. In the DCS group, the size of the rectosigmoid lesion ranged from 2.2 cm to 4.2 cm. Median operative time for the DCS technique was 100 minutes, compared with 150 minutes for rectosigmoidectomy (p = .04). Only 1 of 11 patients (9%) had urinary retention, compared with postoperative urinary retention in 14 of 55 patients (25%) who had undergone rectosigmoidectomy (difference not significant). Only 1 patient, with a 4.2-cm nodule, had a positive margin in the specimen obtained at the second stapling. DCS is a promising technique and may avert rectosigmoidectomy in selected patients.

Abstract
Laparoscopic gastrectomy has become widely used as a minimally invasive technique for the treatment of gastric cancer. When it was first introduced, most surgeons preferred a laparoscopic-assisted approach with a minilaparotomy rather than a totally laparoscopic procedure because of the technical challenges of achieving an intracorporeal anastomosis. Recently, with improved skills and instruments, several surgeons have reported the safety and feasibility of a totally laparoscopic gastrectomy with intracorporeal anastomosis. This review describes the recent technical advances in intracorporeal anastomoses using circular and linear staplers that allow for totally laparoscopic distal, total, and proximal gastrectomies. Data that demonstrate advantages in early surgical outcomes of a total laparoscopic method compared to laparoscopic-assisted operations are also discussed.
