Abstract
Objectives Anastomotic complications after colorectal surgery are one of the most serious outcomes. To address this issue, this study used the newly developed bioabsorbable polyglycolic acid (PGA) sheet to assess its usefulness and safety using two approaches of double stapling technique (DST) after laparoscopic anterior resection (AR) in pig models. Methods Rectal intratissue pressure was assessed after DST anastomosis in two groups, i.e., with (PGA group) or without PGA sheet (nonPGA group), which was sandwiched between the anastomosis in the first approach. In the second approach, after laparoscopic DST anastomosis with PGA sheet attached at anvil side, the clinical short-term outcomes within 1 week and histological findings at 1 week after the surgery were evaluated. Results Assessment of rectal intratissue pressure showed a mean pressure of 9.28 kPa in the PGA group versus 5.78 kPa in the nonPGA group (p = 0.39). The results of clinical short-term outcomes revealed that there were no anastomotic complications. The results of histological findings in anastomotic bowel tissues with PGA sheet were not significantly different from those of the control case. Conclusions The bioabsorbable PGA sheet can be used for colorectal DST anastomosis in animal models and may be a valuable tool for this procedure.

Abstract
PURPOSE In most cases, traditional techniques to perform an anastomosis following gastrointestinal resections lead to successful healing. However, despite focused research in the field, in certain high-risk situations leakage rates remain almost unchanged. Here, additional techniques may help the surgeon to protect the anastomosis and prevent leakage. We give an overview of some of the latest developments on experimental and clinical techniques for induction of anastomotic healing. METHODS We performed a review of the current literature on approaches to improve anastomotic healing. RESULTS Many promising approaches with a high clinical potential are in the developmental pipeline. Highly experimental approaches like inhibition of matrix metalloproteinases, stem cell therapy, hyperbaric oxygen therapy, induction of the hypoxic adaptive response, and the administration of growth factors are still in the preclinical phase. Other more clinical developments aim to strengthen the anastomotic suture line mechanically while shielding it from the influence of the microbiome. Among them are gluing, seaming the staple line, attachment of laminar biomaterials, and temporary intraluminal tubes. In addition, individualized bowel preparation, selectively reducing certain detrimental microbial populations could become the next stage of bowel preparation. Compression anastomoses are evolving as an equivalent technique additional to established hand-sewn and stapled anastomoses. Fluorescence angiography and flexible endoscopy could complement intraoperative quality control additionally to the air leak tests. Virtual ileostomy is a concept to prepare the bowel for the easy formation of a stoma in case of leakage. CONCLUSION A variety of promising diagnostic and prophylactic measures that may support the surgeon in identifying high-risk anastomoses and support them according to their potential deficits is currently in development.

Abstract
A 65-year-old man presented with bloody stool. Colonoscopy revealed a raised tumor in the rectum, above the peritoneal reflection. He underwent endoscopic mucosal resection, but the pathological findings suggested the possibility of residual cancer. We performed laparoscopic low anterior resection using a circular stapling instrument for additional curative surgery. However, we could not insert the shaft of the endoscopic circular stapler from the anus because of anal stenosis due to Whitehead's hemorrhoidectomy the patient had undergone 20 years earlier. Therefore, we planned to use a linear stapler to insert an anvil into the rectum. The cartridge-carrying instrument was inserted from the sigmoidal side, and we performed a side-to-end anastomosis. The patient was discharged without anastomotic leakage or defecation disorder. We present this case because laparoscopic low anterior resection for rectal cancer with anal stenosis has not been previously reported.

Abstract
OBJECTIVE This study aimed to compare outcomes of laparoscopic sleeve gastrectomy (LSG) patients based on three types of staple line reinforcement (SLR): seromuscular suturing (imbrication), absorbable polymer membrane (APM), and bovine pericardial strips (BPS). BACKGROUND LSG represented 67.3 % of bariatric procedures performed in Michigan in 2013, and its prevalence continues to rise. Multiple studies suggest that SLR can potentially reduce the incidence of complications. However, the current literature is limited secondary to a small sample size and is not conclusive on which type of reinforcement technique is best in reducing the risk of complications. METHODS The charts of 1,526 consecutive patients who underwent an LSG from January 2005 to January 2013, by four experienced surgeons, were reviewed. Data include patient demographics, reinforcement technique utilized, length of hospitalization, complications, hospital readmission rates, and mortality. RESULTS Of 1,502 patients who underwent an LSG and met inclusion/exclusion criteria, 373 (24.8 %) were reinforced using imbrication, 269 (17.9 %) with BPS, and 860 (57.3 %) with APM. Patient demographics and complication rates were similar between groups. A statistically significant difference occurred in length of stay, readmission, and reoperation rates (p < 0.01). Length of stay was shortest in the BPS group, but readmission and reoperation rates were statistically higher, and there was a trend towards increased leaks (p = 0.08). CONCLUSIONS A comparison of imbrication, BPS, and APM demonstrated significantly increased readmission and reoperation rates with a trend towards increased leak rates with the use of BPS in LSG patients. Hemorrhage was not statistically different between the three reinforcement techniques.

Abstract
BACKGROUND Anastomotic leakage is a major complication after anterior resection for rectal cancer. The double-stapling technique (DST) is the main method for creating a colorectal anastomosis. However, the rate of anastomotic leakage after DST remains high, and the technical risk factors have not been well established. MATERIALS AND METHODS Five methods of colorectal anastomosis were performed on the porcine rectum and colon: single-stapled double-purse-string (SSDP), DST, side-to-side with a linear stapler (SS-L), side-to-side with a circular stapler (SS-C), and SS-C with hand-sewn reinforcement (n = 6 for each method). In each group, burst pressures were tested, paying special attention to the locations of the first disruptions. The anastomosis line, including staples, was embedded in polyester resin, and polished sections were examined histologically. RESULTS Burst pressures were significantly higher in the SS-L and SS-C than those in the SSDP and DST groups (P < 0.001) and were higher in the SS-C with hand-sewn reinforcement than those in the SS-L and SS-C groups (P < 0.001). Remarkably, in the SSDP, DST, and SS-C groups, the first disruptions occurred on the staple line created by the circular stapler. CONCLUSIONS The experimentally strongest colorectal anastomosis created with instruments currently in use was a SS-C. This anastomosis does not overlap staple lines and does not require a purse-string suture. Hand-sewn reinforcement was effective in increasing the anastomotic strength.

Abstract
BACKGROUND Anastomotic complications, including leaks, stenoses, and bleeding, cause considerable mortality and morbidity after colorectal surgery. OBJETIVE The purpose of this work was to evaluate the effectiveness of bioabsorbable staple line reinforcement in reducing colorectal anastomotic complications. DESIGN This was a prospective randomized clinical study. SETTINGS This study was conducted at a university hospital within a specialized colorectal unit. PATIENTS Patients undergoing left colon resection for a benign or malignant condition were eligible. A total of 302 patients participated, including 154 control subjects and 148 with reinforcement. INTERVENTION Patients were prospectively randomly assigned to reinforcement of circular stapled anastomosis with a bioabsorbable device versus stapled circular anastomosis without reinforcement. MAIN OUTCOME MEASURES The primary end point was the rate of pooled incidences of anastomotic complications (leakage, bleeding, or stenosis). Secondary outcomes were the rate of reoperations and the length of hospital stay. RESULTS Baseline characteristics were similar between both groups. Intention-to-treat analysis revealed that there were no significant differences in the pooled incidences of anastomotic complications (p = 0.821). Regarding individual complications, we did not observe statistical differences between groups, including leakage (6.6% vs 4.8%; p = 0.518), hemorrhage (1.4% vs 1.3%; p = 0.431), or stenosis (2.9% vs 6.8%; p = 0.128). Again, no significant differences were observed in length of stay (7 days; p = 0.242) or rate of reoperation (7.3% vs 9.6%; p = 0.490). A patient (0.3%) in the control group died. LIMITATIONS Sample size calculation was performed including all 3 of the complications, which may render it underpowered to detect differences regarding a specific complication. Anastomoses located within 5 cm from the anal verge were excluded from the study. CONCLUSIONS The results obtained show that bioabsorbable staple line reinforcement in a colorectal anastomosis >5 cm from the anal verge does not reduce the rate of pooled anastomotic complications (ie, leaks, bleeding, or stenosis).

Abstract
BACKGROUND Anastomotic complications, including leaks, strictures/stenoses, and bleeding, cause considerable mortality and morbidity after colorectal surgery. OBJECTIVE The aim of this study was to assess whether the use of a synthetic, bioabsorbable staple line reinforcement material with circular staplers would reduce postoperative anastomotic leakage in patients with a colorectal, coloanal, or ileoanal anastomosis. DESIGN This was a randomized study that compared outcomes in patients in whom the reinforcement material was used with those in patients who were not given the material. SETTINGS This study was conducted at several centers in the United States. PATIENTS The 258 patients (123 in the reinforcement group and 135 control subjects) underwent surgery for a variety of conditions, but most (n = 200) were treated for rectal cancer. MAIN OUTCOME MEASURES The main outcome measures were occurrence of anastomotic leaks and other complications according to the study protocol. RESULTS There were no significant differences in the 2 study groups with respect to age, BMI, ASA physical status, operating time, diagnosis, previous chemoradiotherapy, surgical technique, or 30-day complications, except for a higher rate of small-bowel obstruction (p = 0.03) and anastomotic stricture (p = 0.006) in the control group. The overall anastomotic leak rate was 12% (bioabsorbable staple line reinforcement, 11.4%; no bioabsorbable staple line reinforcement, 12.6%). LIMITATIONS The study was nonblinded and was terminated at the first planned interim analysis because of insufficient power to detect an intergroup difference in anastomotic leak rate in the time allotted for the investigation. CONCLUSIONS Reinforcing the circular staple line in colorectal anastomoses with bioabsorbable material did not significantly affect the anastomotic leak rate but may have reduced anastomotic strictures. Most strictures did not require an anastomotic revision or delay in stoma closure. The bioabsorbable material may positively affect some aspects of the healing of circular stapled colorectal anastomoses; however, additional research on factors associated with anastomotic leakage is needed.

Abstract
BACKGROUND The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. The purpose of this study was to compare prospectively and randomly three different techniques of SLR during LSG. METHODS From April 2010 to April 2011, patients submitted to LSG were randomly selected for the following three different techniques of SLR: oversewing (group A); buttressed transection with a polyglycolide acid and trimethylene carbonate (group B); and staple-line roofing with a gelatin fibrin matrix (group C). Primary endpoints were reinforcement operative time, incidence of postoperative staple-line bleeding, and leaks. Operative time was calculated as follows: oversewing time in group A; positioning of polyglycolide acid and trimethylene carbonate over the stapler in group B; and roofing of the entire staple line in group C. RESULTS A total of 120 patients were enrolled in the study (82 women and 38 men). Mean age was 44.6 ± 9.2 (range, 28-64) years. Mean preoperative body mass index was 47.2 ± 6.6 (range, 40-66) kg/m². Mean time for SLR was longer in group A (14.2 ± 4.2 (range, 8-18) minutes) compared with group B (2.4 ± 1.8 (range, 1-4) minutes) and group C (4.4 ± 1.6 (range, 3-6) minutes; P < 0.01). Four major complications were observed (3.3 %): one leak and one bleeding in group A; one bleeding in group B; and one leak in group C, with no significant differences between the groups. No mortality was observed. CONCLUSIONS SLR with either polyglycolide acid with trimethylene carbonate or gelatin fibrin matrix is faster compared with oversewing. No significant differences were observed regarding postoperative staple-line complications.

Abstract
Purpose. The aim of this study was to compare characteristics of rectal compression and stapled anastomoses at multiple time points. Methods. A total of 50 domestic pigs underwent a rectal anastomosis with a compression device or a circular stapler. They were sacrificed at zero-time, 2 days, 1 week, 1 month, and 3 months. Burst and maximal tolerated pressure and sites of failure, internal diameters, and radiographic leak rates were assessed. Desmosine (elastin) levels were determined. Results. There were no clinical or radiographic leaks. Overall, 10 out of 27 (37%) compression anastomoses burst at higher pressures than the 14 out of 24 (58%) stapled anastomoses. Mean circumference and anastomotic index were greater for the EndoCAR at 1 week and 3 months. Desmosine levels were similar. Conclusions. In the porcine model, compression rectal anastomoses with the EndoCAR had improved bursting pressures and internal circumference compared with circular stapled anastomoses.

Abstract
INTRODUCTION Anastomotic leakage is a serious postoperative complication of open and laparoscopic colorectal surgery, very often associated with higher morbidity and mortality. Despite proper patient selection and surgical technique, anastomotic leakage cannot be avoided. The use of a synthetic, bioabsorbable staple-line reinforcement material for the circular stapler may help reduce its prevalence. METHODS From May to December of 2006, 14 doctors, from 18 hospitals in the United States, performed 117 laparoscopic and open colorectal procedures, in which circular bioabsorbable Seamguard (CBSG; W.L. Gore and Associates, Elkton, MD) was used. RESULTS Eighty-three patients underwent laparoscopic surgery (70.0%) and 34 open surgery (30%). The procedures included low anterior resection in 49 patients (42%), sigmoidectomy in 46 patients (39.5%), left hemicolectomy in 12 patients (10%), and total colectomy in 10 patients (8.5%). Sixty-four patients had benign disease and 36% malignant disease. Intraoperative anastomotic leakage tests identified 4 patients with leakage (3.4%). All 4 patients had a very low anastomosis (1, 3, 4, and 6 cm, respectively, from the anal verge). Two of the leaks resolved without further intervention. A fecal diversion procedure was performed in the other 2 patients, including 1 patient with rectal bleeding, requiring a transfusion. No clinical complications related to use of CBSG were reported. CONCLUSIONS The use of Seamguard in colorectal open and laparoscopic surgery may result in a lower incidence of anastomotic leakage.

Abstract
PURPOSE The leak rate after low anterior resection is in the region of 10% to 15%. The highest risks of anastomotic leak are in anastomoses less than 5 cm from the anal verge. We evaluated the outcome of oxidized regenerated cellulose reinforcement of low rectal anastomosis. METHODS The study group consisted of 108 patients with rectal cancer. Patients with low rectal cancer had low anterior resection with stapled straight low colorectal or coloanal anastomosis without proximal diversion. They were prospectively randomized to either oxidized regenerated cellulose reinforcement or no reinforcement. Data collected included age, sex, hemoglobin percentage, albumin level, histopathologic type of the tumor, anastomotic leak, and stricture. RESULTS The mean age of patients was 56 years, and sex was matched in both groups. Clinical leak occurred in 6 of 38 cases (15.7%) in the group that did not undergo reinforcement versus 2 of 33 (6.1%) in the oxidized regenerated cellulose reinforcement group (P < .01). In the case of a leak, diversion was needed in 3 of 6 patients in the group that did not undergo reinforcement vs no patients in the oxidized regenerated cellulose reinforcement group (P = .05). Generalized peritonitis occurred in 3 patients in the group that did not undergo reinforcement versus no patients in the oxidized regenerated cellulose reinforcement group (P < .01). Length of stay was 4.8 days in the oxidized regenerated cellulose reinforcement group versus 5.9 days in the group that did not undergo reinforcement (P = .047), with no mortalities in either group. CONCLUSION Oxidized regenerated cellulose reinforcement of low rectal anastomosis significantly decreases the risk of postoperative leak in low rectal anastomosis and may reduce the requirement for proximal diversion. Potential benefits include avoidance of a stoma, lower morbidity, shorter hospital stay, and a lower cost of care.

Colorectal anastomotic leak remains one of the most feared post-operative complications, particularly after anterior resection of the rectum with, the shift from abdomino-peritoneal resections to total mesorectal excision and primary anastomosis. The literature fails to demonstrate superiority of stapled over hand-sewn techniques in colorectal anastomosis, regardless of the level of anastomosis, although a high stricture rate was noted in the former technique. Thus, improvements in safety aspects of anastomosis and alternatives to hand-sewn and stapled techniques are being sought. Here, we review alternative anastomotic techniques used to fashion bowel anastomosis. Compression anastomosis using compression anastomotic clips, endoluminal compression anastomotic rings, AKA-2, biofragmental anastomotic rings, or Magnamosis all involve the concept of creating a sutureless end-to-end anastomosis by compressing two bowel ends together, leading to a simultaneous necrosis and healing process that joins the two lumens. Staple line reinforcement is a new approach that reduce the drawbacks of staplers used in colorectal practice, i.e. leakage, bleeding, misfiring, and inadequate tissue approximation. Various non-absorbable, semi or fully absorbable materials are now available. Two other techniques can provide alternative anastomotic support to the suture line: a colorectal drain and a polyester stent, which can be utilized in ultra-low rectal excision and can negate the formation of a defunctioning stoma. Doxycycline coated sutures have been used to overcome the post-operative weakness in anastomosis secondary to rapid matrix degradation mediated by matrix metalloproteinase. Another novel technique, the electric welding system, showed promising results in construction of a safe, neat, smooth sutureless bowel anastomosis. Various anastomotic techniques have been shown to be comparable to the standard techniques of suturing and stapling. However, most of these alternatives need to be accepted and optimized for future use.

Abstract
PURPOSE This study was designed to determine the short-term results of transanal rectocele repair with use of a linear stapler and Bioabsorbable Seamguard. METHODS Ten women (median age, 56.1 y) with obstructed defecation syndrome were enrolled in the study. The preoperative study consisted of a medical history, physical examination, anoscopy, endoanal ultrasound, and defecography. All patients completed a severity score and a visual analog scale for global quality of life, and provided the postoperative dates of complications. RESULTS Overall, the treatment significantly improved the obstructed defecation: the severity score improved from a median of 19.8 +/- 4.2 at baseline to 6.10 +/- 8.2 at one month (P < .005), 5.9 +/- 8.3 at 6 months (P < .005), and 6 +/- 8.3 at one year after the operation (P < .005). A significant improvement was observed in the visual analog scale, which improved from a median of 1.8 +/- 1.4 at baseline to 6 +/- 1.6 at one month (P < .005), 6.6 +/- 2.1 at 6 months (P < .004), and 7 +/- 2.5 at one year (P < .004). A significant improvement was also observed in various symptoms. Only 2 patients manifested urgent defecation. CONCLUSIONS The present study demonstrates that rectocele repair using a linear stapler and Seamguard is a safe, easy procedure, with a very low rate of complications and good immediate outcome.

Abstract
Pancreatic fistula is a major cause of morbidity after distal pancreatic resection. When resections are performed with linear stapling devices, the use of bioabsorbable staple line reinforcement has been suggested to decrease the rate of pancreatic fistula. Our objective was to investigate the incidence of pancreatic fistula when using the Gore Seamguard® staple line reinforcement in stapled distal pancreatic resections. A retrospective review of 30 consecutive patients with stapled distal pancreatectomy was conducted. A broad definition of pancreatic fistula was used. Clinicopathologic factors and outcomes were compared between groups. Pancreatic fistula was diagnosed in 11 of 15 patients (73%) and three of 15 patients (20%) in the Seamguard® and non-Seamguard® groups, respectively ( P = 0.002). Pancreatic parenchymal transection at the neck of the gland was associated with pancreatic fistula, whereas laparoscopic procedures, splenic preservation, or additional organ resection were not. On multivariate analysis, the association between Seamguard® use and pancreatic fistula was significant ( P = 0.005). In conclusion, after introduction of the Gore Seamguard® bioabsorbable staple line reinforcement, we experienced a significant increase in the rate of pancreatic fistula. This experience raises concern about the efficacy of this device in limiting pancreatic fistula after stapled distal pancreatic resection.

Reinforcement does not necessarily reduce the rate of staple line leaks after sleeve gastrectomy. A review of the literature and clinical experiences. Obes Surg 2008; 19:166-172.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (SG) is an accepted bariatric procedure, with an advantaged by a low complication rate. A feared complication is stapler line leak. Buttressing materials have been suggested as a means of reducing staple line leak rates. We analyzed the leak rates from published series to help in demonstrating a potential cause. METHODS The study was institutional review board (IRB) approved retrospectively. A Medline search using the key words sleeve gastrectomy and bariatric surgery obtained 54 articles. Attention was restricted to 11 articles written in English that listed numbers of gastrectomy procedures and leaks. Poisson regression assessed the possibility that patients who received buttressing materials had a reduced rate of leaks. RESULTS Thirty-five patients were evaluated from Greece (15) and the United States (20); two patients developed staple line leaks that appeared to be related to problems associated with buttressing materials. Eleven prior studies and the present series yielded 1,589 procedures, 15 (0.94%) of which were complicated by leaks. The leak rate for patients who were known to have received reinforcement of some sort was 1.45 (95% confidence interval 0.41-3.43) times that for other patients. To detect a difference between 1% and 0.5% as statistically significant in 80% of cases, with a two tailed test and alpha set at 0.05, would require 9,346 procedures. CONCLUSIONS There is no reason to believe, at this point, that reduction in leak rates occur because reinforcement is used. Because the leak rate is small, the routine reinforcement of the staple line after sleeve gastrectomy is questionable at best, although a decrease in hemorrhage has been reported.

Early experience with intraluminal reinforcement of stapled gastrojejunostomy during laparoscopic Roux-en-Y gastric bypass. Obes Surg 2008; 18:525-9.

Abstract
BACKGROUND The use of extraluminal staple-line buttressing material during laparoscopic Roux-en-y gastric bypass has shown the potential to reduce staple-line leak and bleeding. We herein present our early experience with intraluminal reinforcement of linear-cutting stapled gastrojejunal anastomosis with the use of bioabsorbable glycolide copolymer staple-line reinforcement. METHODS Laparoscopic Roux-en-Y gastric bypass was performed in 80 consecutive non-randomized morbidly obese patients. Gastrojejunal anastomosis was performed using a linear-cutting stapler without staple-line reinforcement in 40 patients (group A), while in the other 40 patients (group B), gastrojejunostomy was performed using a linear cutting stapler with intraluminal reinforcement material (bioabsorbable glycolide copolymer). Demographic data were collected. The rate of gastrojejunal anastomotic leak, bleeding, and stricture was determined. RESULTS There was a statistically significant reduction in bleeding complications between the two groups (15% bleeding in group A vs. no bleeding in group B, P value=0.0255). Stricture rate was higher in-group A (10% group A vs. 2.5% in group B); however, the difference was not statistically significant (P value=0.2007). None of our patients developed a gastrojejunal leak. CONCLUSION Intraluminal reinforcement of gastrojejunal anastomosis during laparoscopic gastric bypass is safe and feasible. The use of intraluminal bioabsorbable glycolide copolymer staple-line reinforcement significantly reduces the incidence of gastrojejunal bleeding.
