Salvage abdominal surgery in patients with a retained rectal stump after restorative proctocolectomy and stapled anastomosis.

BACKGROUND: The introduction of surgical stapling instruments has widened the use of restorative proctocolectomy. Too high a distal transection of the rectum can, however, produce a retained rectal stump, which may cause symptoms. A study of the operative and functional data in a consecutive series of patients undergoing salvage surgery for retained rectal stump was undertaken. METHODS: Twenty-five patients referred between January 1990 and September 2000 for pouch dysfunction were identified as having a retained rectal stump. Twenty-two underwent abdominoanal revision. The hospital notes were reviewed and function was assessed during outpatient visits, by postal questionnaire and by telephone interview. RESULTS: Median operating time was 225 (range 170-340) min and median hospital stay was 15 (range 8-48) days. There was no operative death. Five pouches were excised. Seventeen patients were available for functional assessment. Median follow-up was 22.5 (range 4-114) months. Median 24-h frequency before and after operation was 12 (range 4-20) and 6 (range 3-12) respectively, and median night-time frequency was 4 (range 0-8) and 0.5 (range 0-4) respectively. Fifteen patients reported marked subjective improvement in pouch function and quality of life. CONCLUSION: Major revisional surgery for symptomatic retained rectal stump after restorative proctocolectomy with stapled anastomosis was successful in 15 of 22 patients. These results are worse than the outcome following first-time restorative proctocolectomy with anastomosis constructed at the anal level. Pouch-rectal anastomosis should be avoided.

MR imaging in patients with metallic implants.

A total of 305 magnetic resonance (MR) examinations were performed in 236 patients with metallic implants. Most examinations were performed at 0.3 T. The metallic implants included central nervous system shunting devices, tantalum mesh, surgical wire, skin staples, surgical clips, metallic orthopedic devices, and a few miscellaneous metallic objects. Patients with cardiac pacemakers, electrical implants, prosthetic cardiac valves, and aneurysm clips were excluded from MR examinations. The images were reviewed for evidence of metallic artifact. The conspicuity of artifact was related to the composition, mass, orientation, and position of the metallic object in the body. In most instances, the metallic artifact did not interfere with the interpretation of the image. The patients' records were also reviewed for adverse effects noted by each patient during the MR examination. Only two patients reported discomfort that could possibly have been related to their metallic implants, but in both cases it seemed unlikely that the symptoms were actually related to the imaging process. There were no apparent short-term adverse effects demonstrated in these patients.

The stapled gastrointestinal tract anastomosis: incidence of postoperative complications compared with the sutured anastomosis.

Performance of gastrointestinal anastomosis by means of surgical stapling devices has achieved popularity in the last decade even though no detailed study has been reported comparing complications following the stapled anastomosis with those following hand sutured procedures performed by the same surgeons. We have reviewed 812 operative procedures on the gastrointestinal tract performed in one hospital over a four year period. Stapled anastomoses were performed in 472 with 13 (2.8%) complications related to the anastomosis; in 296 sutured anastomoses there were nine (3.0%) related complications. Comparison did not disclose any significant difference in the number of complications in these two groups. In 44 instances wherein the anastomosis contained both staples and sutures, there were no related complications. Further analysis of the patients in each group disclosed that stapling procedures were utilized in a much higher percentage of those operations which were performed under emergency conditions or in the presence of intra-abdominal sepsis, intestinal obstruction, and carcinomatosis. If the technical details of surgical stapling are mastered, this technique appears to be as safe as suturing in the performance of anastomoses in the gastrointestinal tract.

Bilateral lung volume reduction surgery for treatment of emphysema.

Patients suffering from chronic pulmonary emphysema can benefit from a new surgical technique that offers them relief from chronic dyspnea and declining quality of life. Bilateral lung volume reduction surgery (LVRS) involves an innovative surgical stapling technique for removing emphysematous lung tissue. To prevent persistent air leaks, surgeons use bovine pericardium strips to reinforce surgical staple lines created during bilateral LVRS. Perioperative nurses should understand the disease process of chronic pulmonary emphysema, bilateral LVRS techniques, and possible postoperative complications to provide quality nursing care for patients undergoing LVRS procedures.

[Analysis of early and late complications and their origins in Kock continent urinary reservoir following technical modification].

Kock and associates have made a major contribution to the ideal continent urinary diversion by developing a method for creating a continent internal reservoir for urine using the ileum. However, substantial problems have unfortunately resulted due to early and late postoperative complications. In an effort to further elucidate this problem, we herein summarize the incidence of early and late postoperative complications following a series of technical modifications made in patients who underwent Kock continent ileal reservoir construction from our ongoing experience to develop more suitable modifications of this procedure. From January 1985 through December 1991, 47 patients have undergone Kock pouch construction for continent urinary diversion. Our basic technique utilized in this study was slightly modified from that described by Skinner et al. Based on our earlier experience, several changes in the technique were made. One major change is that one row of surgical staples fixes the created nipple to the back wall of the reservoir for the efferent limb, and a further 3-cm longitudinal mucosal incision is made through the outer layer of the intussuscepted ileal nipple and the opposite wall of the reservoir which are sewn to the reservoir edge. A total of eleven patients (11/47) suffered one or more early surgical complications. A 31.8% (7/22) morbidity with an operative mortality rate of 4.3% (2/47) and a 16.0 (4/25) morbidity were observed in the early phase and late phase, respectively. Prolonged urinary leakage from the ileal reservoir and/or through a pin hole in the afferent limb made by surgical staples was observed in six patients (27.3%) in the early phase.(ABSTRACT TRUNCATED AT 250 WORDS)

Stapled hemorrhoidectomy: surgical notes and results.

Recently the surgical treatment of hemorrhoids using a circular stapler device has gained increasing approval. The Longo's procedure reduces the rectal mucosal and hemorrhoid prolapse using a circular stapler to resect transversally a mucosal-submucosal rectal ring in order to restore the correct anatomical relationships of the anal canal structures. The recent availability of a dedicated instrument kit (PPH01 Ethicon Endo-Surgery) allowed an easy diffusion of this technique. From March 1999 to September 2001, 198 patients with III-IV degree hemorrhoids were treated by a single expert surgeon using the dedicated kit instrumentation (PPH01) according to the Longo's technique, adopting some variations from the original procedure: 1) The anal dilator is not fixed to the perianal skin with forceps or stitches but is kept by the assistant. 2) In performing the purse-string suture particular care must be given to the apposition of the stitches at the same level also in the posterolateral side where there is a natural trend to apply the stitches at a lower level; furthermore the last stitch of the purse-string suture must be overlapped to the first one in order to allow a better hemostasis when the knot is tightened. 3) After having performed the purse-string and having resected the mucosa and submucosa, an accurate hemostasis with U-shaped 3/0 vicryl stitches firmly reduces the postoperative bleeding. We recorded pain scores, short- and long-term complications (included moderate-severe pain, persistent pain), recurrences and postoperative hospital stay. The data of the last 40 consecutive patients who underwent stapled hemorrhoidectomy were compared with the data obtained by 40 consecutive patients who underwent Milligan-Morgan diathermic hemorrhoidectomy for III-IV degree non-circumferential hemorrhoids by the same surgeon. In the 198 stapled hemorrhoidectomy cases the rate of postoperative moderate-severe pain and persistent pain were 6% and 2.5% respectively, the rate of short-term and long-term bleeding were 4.5% and 3.5%, the recurrence rate was 2.5%. The mean postoperative stay was 1.6 days. The stapled group had significantly lower postoperative moderate-severe pain, bleeding and soiling than the Milligan-Morgan group.

Intestinal anastomoses.

Anastomotic dehiscence remains the main cause of morbidity and mortality of intestinal resections, mainly the colorectal (77, 95, 110). Very often in the literature the words dehiscence and fistula are misused for the same meaning. Nevertheless, attention must be paid to the fact that these two situations may be distinct. Dehiscence is defined as the failure of healing of the anastomoses, while fistula is the leakage of the intestinal content into the peritoneal cavity. So, the evidence of fistula is always accompanied by dehiscence, although a dehiscence may not develop into a fistula, should it be blocked by omentum or surrounding organs (110, 117). The incidence of overt dehiscence varies from 0.1% to 30% in the literature (13, 15, 17, 27, 31, 40, 44, 46, 76, 77, 81, 96, 113, 120, 123, 126, 133, 135). The Colon Cancer Project of the Saint Mary's Hospital in London, a multicentric study of patients submitted to bowel resections revealed a post operative mortality of 22% in patients with dehiscence and 7% for uncomplicated anastomoses. This led to the struggle various authors to achieve better results, regarding techniques and suture materials, such as the number of planes involved, inverted or everted sutures, wound healing and the influence of local and systemic factors, like infections, antibiotics, NSAIDs on sutures. Recently, surgical stapling gained importance among surgeons, due to its technical advantages. However, this is still very controversial and must undergo further investigations (93, 107, 109, 112, 115, 116). So, in order to understand the pathophysiology of the complications and to reduce morbidity and mortality, related to intestinal anastomoses, it is necessary to study the events involved in intestinal healing after resection, as well as the technique, materials used and the factors related to anastomotic failure.

Pouch and Roux-en-Y reconstruction after gastrectomy.

We evaluated a reconstruction procedure of the upper gastrointestinal tract after total gastrectomy with the exclusive use of the EEA, GIA, and TA surgical stapling devices (United States Surgical Corp, Norwalk, Conn). Twenty patients with gastric carcinoma entered the study. A total gastrectomy and lymphadenectomy was performed in each patient and the upper gastrointestinal tract was reconstructed by the Roux-en-Y technique with the creation of a Hunt-Lawrence-Rodino pouch. For all operational steps, surgical staplers were used exclusively, as follows: (1) duodenal closure, GIA or TA; (2) Roux-en-Y anastomosis, EEA 25; (3) pouch construction, GIA (three to four times); (4) esophagojejunostomy, EEA 25; and (5) pouch closure, TA 55 or 90. There was a one-hour difference in operating time between patients operated on exclusively by the staple technique and TNM-matched patients operated on manually. Four patients suffered from general complications. Two patients had clinically relevant suture deficiencies. We concluded that current reconstruction methods after gastrectomy that fulfill the reservoir function (pouch) and reflux prevention (Roux-en-Y reconstruction) can be achieved by the combination and systematic use of straight and circular staplers. The advantages are intraoperative time saving and a relaxation of limitations imposed on an abdominal intervention by age and localization of the tumor.

Determination of cell viability after laparoscopic tissue stapling in a porcine model.

BACKGROUND AND PURPOSE: Surgical stapling devices are often used to secure the distal ureter along with a cuff of bladder during laparoscopic nephroureterectomy. As the viability of cells within the stapled tissue would be important in patients with upper urinary-tract transitional-cell carcinoma, we determined the viability of cells within the lines of various commercially available staplers in a porcine model. MATERIALS AND METHODS: Four laparoscopic stapling devices were used: two vascular and two tissue designs (US Surgical, Norwalk, CT, and Ethicon, Cincinnati, OH). The devices were deployed across a portion of the bladder, much as they would be during a nephroureterectomy to create a bladder cuff while excising the distal ureter. The animals were sacrificed 6 weeks later, and the stapled sites were harvested for histopathologic examination by an experienced genitourinary pathologist (PH). RESULTS: Grossly, there were no visible staples at harvest of the stapled bladder and the ureterovesical junction, with a completely healed bladder being seen in all four animals. On histologic examination with hematoxylin and eosin staining, there were distinctly viable cells within the staple lines of the ureterovesical junction and the bladder wall, similar to the unstapled control tissue. There were viable cells in all samples of tissues stapled by either vascular or tissue staplers. CONCLUSIONS: Deployment of both vascular and tissue staplers resulted in viable cells within the staple lines at the ureterovesical junction and bladder wall in this porcine model. There is a potential risk of tumor recurrence at the stapled site in patients who have the ureter and bladder cuff secured with these devices during laparoscopic nephroureterectomy for upper-tract transitional-cell carcinoma. Despite this concern, to date, over a period of 13 years, clinical experience has not revealed a single case of tumor recurrence within the stapled cuff of bladder. Careful endoscopic evaluation of the stapled bladder-cuff site after laparoscopic nephroureterectomy should minimize the potential for local tumor recurrence.

Reduction of infectious morbidity with uterine stapling device.

Due to the recent development of absorbable surgical staples, application of gynecologic stapling methods has expanded to the field of obstetrics. Several studies have been published presenting the results of utilization of a novel hysterotomy and uterine stapling device for cesarean section (Poly CS-57, U.S. Surgical Corp, Norwalk CT). A review of all available data was analyzed to determine the rate of infectious morbidity secondary to the use of the device. Four studies fulfilled several criteria, including use of proper controls. A total of 383 patients were included in these studies with an infection rate of 6.4% (12/187) versus 16.3% (32/196) for the stapled and non-stapled (traditional sutured) group, respectively (p less than 0.001). The individual investigations attributed the decreased infection rate to reductions in blood loss and incisional hematoma formation and decreased reactivity of copolymer absorbable staples.

Randomised, controlled study of transhepatic obliteration of varices and oesophageal stapling transection in uncontrolled variceal haemorrhage.

Percutaneous transhepatic obliteration and surgical stapling transection of the oesophagus with the EEA gun were compared prospectively in the treatment of uncontrolled oesophageal variceal haemorrhage unresponsive to conservative measures. Twenty patients with cirrhosis, with a patient portal vein and who were considered suitable for general anaesthesia and surgery, were randomised to two treatment groups (10 patients each). Immediate arrest of haemorrhage was achieved in 17 patients (nine surgery, eight obliteration). In one other patient, stapling transection succeeded where attempted transhepatic obliteration failed, and in another patient obliteration succeeded where attempted transection had failed. One patient continued to bleed and died following attempts at both procedures. Two other patients also died in hospital, without rebleeding following surgery. Variceal rebleeding during the same hospital admission occurred in two patients in the obliteration group and in none after surgery. Oesophageal stapling transection compares very favourably with a non-surgical technique such as transhepatic obliteration of varices in the emergency treatment of uncontrolled variceal haemorrhage in patients with moderate liver failure.

Colostomy closure with the automatic surgical stapler.

Surgical stapling instruments have been used successfully in gastrointestinal anastomosis. A surgical technique using the staples to close a loop colostomy in gynecologic oncology patients is presented. The procedure shortens operating time and results in an enlarged anastomotic site, thus minimizing the possibility of obstruction at the site.

Stapling in esophageal surgery.

Indications for esophageal surgery include the closure of tears from foreign bodies and incisions for their removal, esophageal anastomosis after removal of diseased or nonfunctional segments, esophagogastric anastomosis after major gastric resection, removal of esophageal diverticula, resection of fistulas, and esophageal reconstructive surgical techniques. The potential use and application of surgical stapling instruments for these esophageal disorders in the veterinary patient are discussed.

Pneumonectomy by "en masse" stapling of hilar vessels.

Since the development of automatic surgical stapling instruments in the Soviet Union in the 1950s and their description in the American literature in 1961, American surgeons have used them for a variety of pulmonary resections. However, there is no account of their use in this country for pneumonectomy by "en masse" stapling of the hilar structures. We have used this whenever it was applicable in 41 consecutive pneumonectomies since 1967. There were 2 postoperative deaths, 1 due to pulmonary embolism and the other to myocardial infarction. There were no complications attributable to the operative technique used. The only empyema developed nine months postoperatively and was not accompanied by bronchial fistula. Cancer-free survival was 43% at two and one-half years and 33% at five years. The technique of en masse stapling of hilar vessels renders pneumonectomy easier, safer, and faster than the technique of individual ligation.

Postoperative assessment of surgical clip position in 16 dogs with cancer: a pilot study.

Metallic hemoclips or surgical staples were inserted in 16 tumor-bearing dogs at the time of surgical resection of the tumor. Orthogonal radiographs were taken immediately postoperatively and after wound healing to visualize the location and number of hemoclips or metallic staples. A shift in hemoclip/staple position was identified in nine dogs, mainly from positioning during radiography. In three dogs, an absolute shift in marker position was identified. Based on this study, it appears that the placement of surgical clips is potentially useful in identifying the tumor bed, which may be of benefit in establishing radiation treatment fields.

Per-oral circular stapler in laparoscopic Roux-en-Y gastric bypass.

Circular staplers are used to create the gastrojejunostomy of the Roux-en-Y gastric bypass. The anvil of the stapler can be placed within the pouch by way of the oropharynx or trans-abdominally, but these methods have limitations. The SurgASSIST Computer Mediated Stapler (Power Medical Interventions, New Hope, PA, USA) is a new technology that changes surgical stapling. The staplers are closed and fired under surgeon control by a computer for better accuracy and reliability. It has a 21-mm stapler, which can be passed orally for endoluminal stapling. The SurgASSIST has several advantages over the traditional circular stapled gastrojejunal anastomosis, including no need to dilate trocars to accommodate the stapler through the abdominal wall and decreased wound infections.

Surgical treatment of emphysema using bovine pericardium strips.

Chronic pulmonary emphysema (CPE) damages lung tissue, causing it to lose elasticity and no longer exchange oxygen and carbon dioxide efficiently. In the past, lung transplantation was the only surgical treatment for CPE. Lung volume reduction surgery (LVRS) using bovine pericardium strips is a surgical approach that removes emphysematous lung tissue, allows healthy lung tissue to reexpand, and improves the functioning of the intercostal muscles and diaphragm. Surgical stapling devices buttressed with strips of bovine pericardium are used in LVRS procedures to reduce air leaks along staple lines. Patients with CPE who have undergone LVRS procedures using bovine pericardium strips have experienced a dramatic increase in their ability to exchange air, allowing them to have more normal lifestyles.
