Management of peritoneal tear during endoscopic extraperitoneal inguinal hernioplasty.

BACKGROUND: Peritoneal tear during endoscopic extraperitoneal inguinal hernioplasty (TEP) results in pneumoperitoneum and loss of extraperitoneal space. To avoid bowel adhesions, internal herniation, and mesh migration, closure of the peritoneal opening is preferred. The present study was conducted to evaluate the efficacy of various operative techniques for the closure of peritoneal laceration. METHODS: Between April 2000 and May 2001, 100 consecutive patients undergoing 123 TEPs were recruited for the present study. The incidence of peritoneal tear and techniques for the closure of peritoneal opening were documented. Operative time and postoperative morbidity were compared among groups for which different closure methods of peritoneal laceration were used. RESULTS: The incidence of peritoneal tear was 47%. The mean operative times of unilateral TEPs with and without peritoneal laceration were 66 min and 53 min, respectively (p<0.05). Techniques for the closure of the peritoneal opening included endoscopic stapling (n = 12), endoscopic suturing (n = 14), and pretied suture loop ligation (n = 21). The mean operative times for unilateral TEPs with endoscopic stapling, pretied suture loop ligation, and endoscopic suturing of peritoneal tear were 53, 64, and 82 min, respectively (p<0.05). Comparison of postoperative morbidity showed no significant differences among the three groups. CONCLUSION: Peritoneal tear is a frequent and challenging intraoperative event during TEP. Its occurrence significantly prolongs the length of operation. Endoscopic stapling and pretied suture loop ligation are safe and quick techniques for the closure of peritoneal tear during TEP.

Stapled hemorrhoidopexy compared with conventional hemorrhoidectomy: systematic review of randomized, controlled trials.

PURPOSE: This study was designed to determine whether conventional hemorrhoidectomy or stapled hemorrhoidopexy is superior for the management of hemorrhoids. METHODS: A systematic review of all randomized trials comparing conventional hemorrhoidectomy with stapled hemorrhoidopexy was performed. MEDLINE, EMBASE, and Cochrane Library databases were searched using the terms "hemorrhoid*" or "haemorrhoid*" and "stapl*." A list of clinical outcomes was extracted. Meta-analysis was calculated if possible. RESULTS: Fifteen trials recruiting 1,077 patients were included. Follow-up ranged from 6 weeks to 37 months. Qualitative analysis showed that stapled hemorrhoidopexy is less painful compared with hemorrhoidectomy. Stapled hemorrhoidopexy has a shorter inpatient stay (weighted mean difference, -1.02 days; 95 percent confidence interval, -1.47 to -0.57; P = 0.0001), operative time (weighted mean difference, -12.82 minutes; 95 percent confidence interval, -22.61 to -3.04; P = 0.01), and return to normal activity (standardized mean difference, -4.03 days; 95 percent confidence interval, -6.95 to -1.10; P = 0.007). Studies in a day-case setting do not prove that stapled hemorrhoidopexy is more feasible than conventional hemorrhoidectomy. Stapled hemorrhoidopexy has a higher recurrence rate (odds ratio, 3.64; 95 percent confidence interval, 1.40-9.47; P = 0.008) at a minimum follow-up of six months. CONCLUSIONS: Although stapled hemorrhoidopexy is widely used, the data available on long-term outcomes is limited. The variability in case selection and reported end points are difficulties in interpreting results. Stapled hemorrhoidopexy has unique potential complications and is a less effective cure compared with hemorrhoidectomy. With this understanding, it may be offered to patients seeking a less painful alternative to conventional surgery. Hemorrhoidectomy remains the "gold standard" of treatment.

Prospective randomized comparison of linear staplers during laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: The development of laparoscopic linear staplers has enabled minimally invasive approaches to bariatric surgery, but there have been no comparison studies of the two current 6-row devices. We report our experience with a prospective randomized comparison of 6-row linear staplers during laparoscopic Roux-en-Y gastric bypass (LRYGBP). METHODS: From January to March 2003, 100 patients were randomly assigned to undergo LRYGBP with either an Endo-GIA Universal 6-row stapler (USSC) or the ETS-Flex 6-row stapler (Ethicon). Mean preoperative BMI was 49+/-8 for 50 Endo-GIA patients, and 49+/-7 for 50 ETS-Flex patients. Parameters measured included quantity of cartridges, handles, hemoclips, estimated blood loss, misfires, OR time, postoperative leaks and bleeds, and cost. RESULTS: Mean follow-up was 135 days (range 90- 180). The ETS-Flex group experienced significantly more misfires (28% vs 2%, P <.001), hemoclips applied (30+/-9 vs 21+/-7, P <.001), estimated blood loss (132+/-56 vs 100+/-32 ml, P <.001) and OR time (66+/-19 vs 58+/-13 mins, P <.02) compared with the Endo-GIA group respectively. There was one postoperative leak associated with the ETS-Flex group and two postoperative bleeds with the Endo-GIA group, which were not a significant differences. The Endo-GIA group averaged $319 more per case for staple cost. CONCLUSION: While the ETS-Flex stapler was less expensive, it was associated with more technical failures requiring surgeon intervention to reduce potential patient morbidity, compared with the Endo-GIA.

The single-stapled ileo pouch anal anastomosis: a reasonable compromise.

Minimal anal sphincter disruption and preservation of the transitional epithelium during ileal pouch anal anastomosis (IPAA) are believed to play important roles in improving functional outcome. As a result, many surgeons have abandoned the traditional mucosectomy in favor of a double-stapled technique. The natural history of the retained colonic epithelium that occurs with this approach is uncertain. The authors have employed a technique of single circular-stapled IPAA, which accomplishes both of the described goals, while insuring that all the colonic mucus is removed during mucosectomy. We present a series of patients (n = 39) undergoing IPAA with transanal mucosectomy and a circular stapled anastomosis. The series consists of 16 males and 23 females with a mean age of 33.4 +/- 1.7 years. Twenty-nine patients had temporary ileostomies (2 not closed yet), and 10 did not. Pelvic sepsis occurred in two patients. However, three (9%) patients developed anastomotic sinus tracts that delayed ileostomy closure. With a follow-up of 24.0 +/- 3.2 months, the mean number of bowel movements are: day 6.4 +/- 0.4; night 1.1 +/- 0.2. Continence has been good or excellent in 97 per cent of patients during the day and 86 per cent at night. Therefore, this series indicates that good to excellent functional results following IPAA in the vast majority of patients can be accomplished with a transanal mucosectomy and a single stapled IPAA anastomotic technique. These results are comparable with those obtained with the double stapling technique without risk of retained rectal mucosa. Therefore, this technique provides good functional results because of minimal anal sphincter stretching, while at the same time insuring removal of all abnormal colonic epithelium.

Does experience preclude leaks in laparoscopic gastric bypass?

BACKGROUND: Improved outcomes of laparoscopic Roux-en-Y gastric bypass (LRYGB) have been demonstrated once pratice has moved beyond the learning curve. However, there is no evidence that experience has a favorable impact on the incidence of leaks. This study evaluated the incidence of staple-line leaks as experience accrued in a university-based bariatric surgery program. METHODS: Prospectively collected data on our first 200 patients undergoing LRYGB since July 1998 were analyzed. Linear staplers were used to divide the stomach and to create a side-to-side jejunojejunostomy. A side-to-side cardiojejunostomy was created using a 21-mm circular stapler. Patient characteristics, operative data, and outcomes were evaluated chronologically with comparison of outcomes between quartiles. RESULTS: Staple-line leaks developed in 9 (4.5%) of the first 200 patients undergoing LRYGB. Among the 200 patients were 190 women (95%). The median age of the patients was 48 years (ranges, 24-62 years), and their body mass index was 43 kg/m(2) (ranges, 32-59 kg/m(2)). As surgeons' experience increased over time, there was a significant increase in the weight of patients and the percentage of patients with previous abdominal operations. There also was a significant decrease in conversion rates and operative times. Leaks occurred in six patients at the cardiojejunostomy (3%), in two patients jejunojejunostomy (1%), and in one patient at the excluded stomach (0.5%). Of the 50 leaks that occurred in each quartile, there were in the 3 in the 1st quartile, 1 in the 2nd quartile, 2 in the 3rd quartile, 3 in the 4th quartile. The differences were not significant. There was no correlation between the number of LRYGBs, and the occurrence of a leak (p = 0.59 confidence interval -0.13-0.22). CONCLUSIONS: The incidence of staple-line leaks appears to be independent of the number of LRYGBs performed. These data suggest that surgeons' experience may not eliminate anastomotic complications experienced by patients undergoing LRYGB.

Laparoscopic sigmoid resection: a comparative experimental study between double-stapling and foreign material free-biostent technique (TESA). Transient endoluminally stented anastomosis.

In current clinical practice the "double-stapling technique" is the standard for reanastomosis following minimally invasive sigmoid resection. In the present study, we compared the TESA technique (transient endoluminally stented anastomosis) with conventional stapled anastomosis and evaluated the effect of remnant foreign material on follow-up examination with endosonography. Laparoscopic sigmoid resection was performed in 12 pigs (mean weight 63+/-5.9 kg). Animals were randomly divided into two groups: In Group A, reanastomosis was performed following a standard technique using a 29-mm circular stapler. In Group B, the TESA technique using a resorbable radiopaque stent of polyglycolic acid was applied. The anastomosis was examined by plain x-ray on days 1, 7, and 14, and by contrast enema on day 42, respectively. Endosonography, macroscopic inspection, and histological evaluation of the anastomosis were performed on day 42. All anastomoses in group A were patent. In one animal in Group B stent displacement with subsequent leak of the anastomosis was observed. Circumferential length of the anastomosis on day 42 did not differ between the groups (Group A: 8.00+/-0.45 cm vs. Group B: 7.8+/-2.0 cm, p = 0.82). The duration of the operation was 130+/-27 minutes in Group A and 100+/-18 minutes in Group B (p = 0.06). Weight gain was equal: Group A: 24+/-9.6 kg vs. Group B: 24+/-5.0 kg, p = 0.74. Endosonography on day 42 postoperatively in the area of the anastomosis in group A was impaired due to metallic staples. TESA is a competitive method for reanastomosis following laparoscopic sigmoid resection. In contrast to the conventional technique, the anastomosis is free of foreign material 1 month after the operation, which facilitates follow-up examinations with endosonography as well as other imaging diagnostics.

Stapled haemorrhoidopexy in fourth degree haemorrhoidal prolapse: is it worthwhile?

INTRODUCTION: Ten years after the introduction of stapled haemorrhoidopexy few studies have stratified patients by degree of haemorrhoidal disease when analysing results. Objective The aim of this study was prospectively to evaluate 116 patients who underwent stapled anopexy conducted by the same surgeon for III or IV degree haemorrhoidal prolapse. MATERIALS AND METHODS: One hundred and sixteen consecutive patients affected by symptomatic haemorrhoids of III or IV degree underwent stapled anopexy using the technique described by Longo in the period January 2001 to October 2003. Mean follow-up was 28.1 months. Fischer's exact test was used for statistical analysis. Results, in terms of morbidity and recurrence rates, were stratified according to degree of haemorrhoidal disease. RESULTS: There was no statistically significant difference between the results for third degree compared with fourth degree prolapse although there was a trend towards increased incidence of postoperative bleeding and recurrence. CONCLUSION: Third degree haemorrhoidal prolapse remains the best indication for stapled haemorrhoidopexy. This procedure may also be indicated in fourth degree haemorrhoidal prolapse. Patients with fourth degree haemorrhoids may be subjected to this procedure following adequate discussion of the outcome.

Endoscopic treatment of postoperative hemorrhage from a stapled colorectal anastomosis.

We present the sixth reported case of endoscopic electrocoagulation to successfully treat postoperative hemorrhage from a stapled colorectal anastomosis. A literature review revealed 17 patients with postoperative hemorrhage from a combined total of 775 patients (1.8 per cent) after stapled colorectal anastomosis requiring blood transfusion and/or emergency surgery. Twelve of the 17 cases involved a circular stapler (71 per cent) used during an anastomosis to the rectum (69 per cent). Nonoperative therapy was successful in 14 of the 17 patients (82 per cent), using endoscopic electrocoagulation in six patients (43 per cent) and blood transfusion alone in another six patients (43 per cent). In follow-up there was one death (cardiac) and two anastomotic fistulas (one requiring temporary colostomy) in the nonoperative group. Both anastomotic fistulas occurred following hemorrhage from an anastomosis to the rectum using the circular stapler, one after endoscopic electrocoagulation and the second after blood transfusion alone. In summary, postoperative hemorrhage from a stapled colorectal anastomosis, although rare, is most likely to occur in a colorectal anastomosis constructed with the circular stapler. Nonoperative treatment is usually successful. Endoscopic electrocoagulation may be safely and effectively used in the early postoperative period to cease unremitting anastomotic hemorrhage.

Laparoscopic intraperitoneal onlay mesh repair of incisional hernia.

Improvements in laparoscopic techniques and equipment have engendered many new intraabdominal procedures. Laparoscopic hernioplasty was used in 11 patients with 12 incisional abdominal hernias. All repairs were made with an intraperitoneal onlay patch of expanded polytef Gore-Tex DualMesh Biomaterial. The patch was secured by whole-thickness sutures, tied subcutaneously through stab holes, and staples between the sutures to cover the hernia defect without excision of the hernia sac. There were three postoperative complications: one seroma, one hematoma, and one infection. These complications successfully healed without reoperation. No recurrence was observed during a follow-up of 8-21 months (average 15 months). It is concluded that laparoscopic incisional hernioplasty using the new Gore-Tex DualMesh Biomaterial, which is securely sutured and stapled on the abdominal wall, is a promising minimally invasive procedure. Continued follow-up is necessary to determine the long-term results.

Laparoscopic repair of paraumbilical ventral hernia with increasing size in an obese patient.

We report a case of paraumbilical ventral hernia with increasing size over 1 year which was successfully repaired using laparoscopic techniques. The repair was made using a 1-mm-thick expanded polytetrafluoroethylene patch inserted intraperitoneally and then stapled to the anterior abdominal wall over the defect. This laparoscopic repair is easily accessible, is considered to reduce morbidity and is thus recommended as the first choice of treatment for ventral hernia.

Endosonographic evidence of injury to the internal anal sphincter after low anterior resection: long-term follow-up.

PURPOSE: Transanal stapled anastomosis has been associated with continence disturbances and reduced postoperative anal sphincter function. The aim of the present work was to study the effect of transanal stapling on anal sphincter morphology by endoanal ultrasound. METHODS: Thirty-nine consecutive patients undergoing stapled low anterior resection for rectal carcinoma were assessed. Each patient was assessed by endoluminal ultrasound before surgery, immediately after surgery, and at 3, 6, 9, 12, and 24 months after surgery. RESULTS: There were no preoperative internal anal sphincter defects observed. Three female patients were observed to have preoperative evidence of external anal sphincter defects. After low anterior resection, seven patients were found to have internal anal sphincter defects, which persisted after the two-year follow-up. There were no additional external anal sphincter injuries. Three patients with internal anal sphincter injuries required the use of pads for poor bowel function. CONCLUSIONS: Up to 18 percent of patients who underwent stapled low anterior resection had long-term evidence of internal anal sphincter injury. The external sphincter does not appear to be affected by the procedure.

Staple line coverage with absorbable mesh after thoracoscopic bullectomy for spontaneous pneumothorax.

BACKGROUND: Thoracoscopic simple bullectomy for primary spontaneous pneumothorax (PSP) has a relatively high postoperative recurrence rate and sometimes results in postoperative air leakage. One of the reasons for postoperative recurrence is the regrowth of bullae around the staple line. Therefore, reinforcement of the visceral pleura around the staple line is a reasonable way to prevent postoperative air leaks and recurrence. This study was done to determine the efficacy in preventing postoperative air leak and recurrent pneumothorax of widely covering the staple line with absorbable mesh after thoracoscopic bullectomy. METHODS: Wide coverage of the staple line with absorbable mesh was performed on 114 patients with PSP. These patients were retrospectively compared with 126 patients who underwent thoracoscopic simple bullectomy alone. RESULTS: The postoperative duration of chest drainage in the coverage group (mean, 1 day; range, 0-5) was significantly shorter than that in the simple bullectomy group (mean, 3 days; range 0-20). A prolonged air leak (>7 days) occurred in six patients in the simple bullectomy group, but there were no such leaks in the coverage group. Recurrent pneumothorax occurred in three patients (2.6%) in the coverage group and 12 patients (9.5%) in the simple bullectomy group. CONCLUSION: Wide coverage of the staple line with absorbable mesh is effective in preventing postoperative air leak and in decreasing the recurrence rates of PSP.

Reinterventions after complicated or failed stapled hemorrhoidopexy.

BACKGROUND: Stapled hemorrhoidopexy has become increasingly popular over the past five years, mainly because of the assumption that it is associated with less pain. However, persistent tags and recurrence might represent a problem, because piles are not excised and severe complications requiring surgery have been occasionally reported. The aim of the present study is to analyze the causes for and the outcome of reintervention following either severely complicated or failed stapled hemorrhoidopexy. METHODS: A total of 232 primary stapled hemorrhoidopexies and 65 reinterventions after stapled hemorrhoidopexy were performed by the authors in five centers devoted to colorectal surgery. Twelve patients of the latter group had the stapled hemorrhoidopexy performed in one of these centers. Thirty-five were males and 30 were females. The mean age was 50 (range, 29-81) years. In all cases the primary indication for stapled hemorrhoidopexy was either third-degree or fourth-degree symptomatic hemorrhoids. In all patients submitted to reoperation the diagnosis of either severely complicated or failed stapled hemorrhoidopexy was made. The clinical history of all of these patients was carefully studied and all underwent inspection, digital exploration, and proctoscopy. After the reintervention, proctoscopy was performed in 61 patients (92 percent) after a median follow-up of 5.5 (range, 1-36) months. RESULTS: Our reoperation rate after stapled hemorrhoidopexy was 11 percent. The most frequent indications for reintervention were persistent, severe anal pain (visual analog pain score higher than 7) in 29 patients (45 percent), severe postoperative bleeding in 20 (31 percent), anal fissure in 16 (21 percent), prolapsing piles in 12 (18 percent), rectal polyp in 11 (16 percent), anorectal sepsis in 11 (16 percent), and fecal incontinence in 7 (11 percent). Thirteen different types of reintervention were needed. Excisional hemorrhoidectomy, removal of staples, and fissurectomy and/or internal sphincterotomy were the most frequent operation (n = 41). A decrease in anal pain, as measured by visual analog pain score, was observed one month after reintervention, compared with that measured preoperatively (from 5.6 +/- 3.6 to 3.0 +/- 2.9) (P < 0.001). Bleeding requiring treatment occurred in six cases (10 percent), anal stricture requiring dilation occurred in three (5 percent), and fecal incontinence in three (5 percent). Proctoscopy showed no recurrences in 52 cases (80 percent) after the reintervention. CONCLUSION: Pain and bleeding mostly caused by piles, fissures, and retained staples were the most frequent causes for reoperation after stapled hemorrhoidopexy. Reintervention was associated with a high bleeding and soiling rate, but was effective in treating pain and other symptoms in the majority of patients. Because of the wide spectrum of different interventions required, a failed or complicated stapled hemorrhoidopexy might be better treated by an experienced colorectal surgeon.

Aboral pouch with preserved duodenal passage--new reconstruction method after total gastrectomy.

A new reconstruction method--the aboral pouch with preserved duodenal passage--has been introduced after total gastrectomy. After removal of the stomach, preparation of the Roux loop and construction of the esophago-jejunostomy, a jejuno-duodenostomy is performed approximately 50 cm away from the esophageal anastomosis between the Roux limb and the duodenal stump. Right below this second anastomosis, the Roux limb is closed with a stapling device to provide a unidirectional food passage through the duodenum. The aboral pouch is constructed as a side-to-side anastomosis between the Roux limb under the stapled segment and the aboral end of the Y limb. The advantages of the reservoir-constructing methods and the interposition methods are combined in this new reconstruction type. Our experiences of 17 cases having undergone this reconstruction method are presented.

Subtalar staple arthroereisis for planovalgus foot deformity in children with neuromuscular disease.

Twenty-two patients (34 feet) with severe, flexible, planovalgus feet due to neuromuscular conditions were treated with subtalar staple arthroereisis. Patients were followed up for an average of 5 years (range, 2.5-9 years). Of the 34 feet, 18 did not require revision surgery; however, the remaining 16 feet required revision at an average of 39 months after surgery (range, 9-63 months). Revision procedures consisted of hardware removal in four cases, repeated subtalar stapling in one, triple arthrodesis in two, and calcaneal with or without cuboid and cuneiform osteotomy in nine feet. The long-term results of subtalar staple arthroereisis were unpredictable, and although it was effective in approximately half of our patients, we no longer recommend this procedure for the correction of the neuromuscular planovalgus foot deformity.

A comparison of hand-sewn versus stapled ileal pouch anal anastomosis (IPAA) following proctocolectomy: a meta-analysis of 4183 patients.

OBJECTIVE: Using meta-analytical techniques, the study compared postoperative adverse events and functional outcomes of stapled versus hand-sewn ileal pouch-anal anastomosis (IPAA) following restorative proctocolectomy. BACKGROUND: The choice of mucosectomy and hand-sewn versus stapled pouch-anal anastomosis has been a subject of debate with no clear consensus as to which method provides better functional results and long-term outcomes. METHODS: Comparative studies published between 1988 and 2003, of hand-sewn versus stapled IPAA were included. Endpoints were classified into postoperative complications and functional and physiologic outcomes measured at least 3 months following closure of ileostomy or surgery if no proximal diversion was used, quality of life following surgery, and neoplastic transformation within the anal transition zone. RESULTS: Twenty-one studies, consisting of 4183 patients (2699 hand-sewn and 1484 stapled IPAA) were included. There was no significant difference in the incidence of postoperative complications between the 2 groups. The incidence of nocturnal seepage and pad usage favored the stapled IPAA (odds ratio [OR] = 2.78, P < 0.001 and OR = 4.12, P = 0.007, respectively). The frequency of defecation was not significantly different between the 2 groups (P = 0.562), nor was the use of antidiarrheal medication (OR = 1.27, P = 0.422). Anorectal physiologic measurements demonstrated a significant reduction in the resting and squeeze pressure in the hand-sewn IPAA group by 13.4 and 14.4 mm Hg, respectively (P < 0.018). The stapled IPAA group showed a higher incidence of dysplasia in the anal transition zone that did not reach statistical significance (OR = 0.42, P = 0.080). CONCLUSIONS: Both techniques had similar early postoperative outcomes; however, stapled IPAA offered improved nocturnal continence, which was reflected in higher anorectal physiologic measurements. A risk of increased incidence of dysplasia in the ATZ may exist in the stapled group that cannot be quantified by this study. We describe a decision algorithm for the choice of IPAA, based on the relative risk of long-term neoplastic transformation.
