Local recurrence following total mesorectal excision with double-stapling anastomosis for rectal cancers: analysis of risk factors.

This study reviewed the local recurrence rate in patients who had undergone total mesorectal excision and double-stapling low anterior resection for mid and distal rectal cancers. It also aimed to identify risk factors for local recurrence through univariate and multivariate analyses. Consecutive patients with rectal cancers within 12 cm of the anal verge treated with total mesorectal excision and double-stapling low anterior resection from August 1993 to December 2000 were studied. The demographic data, operative details, tumor characteristics, and follow-up data were collected prospectively. Factors that might affect the local recurrence rate were analyzed with univariate and multivariate analyses. A total of 270 patients were included in the study (156 men, 114 women). The mean +/- SD age was 64.83 +/- 11.27 years. The mean +/- SD level of the tumor was 7.17 +/- 1.90 cm. All anastomoses were performed within 5 cm of the anal verge. During the mean follow-up of 35.5 months, 12 patients developed local recurrence. The 5-year actuarial local recurrence rate was 7.3%. The presence of lymphovascular invasion and the resection margin of < or = 1 cm were found to be risk factors for local recurrence in the univariate analysis. In the multivariate analysis, the presence of lymphovascular invasion was the only independent factor for local recurrence. In the group of patients with lymphovascular invasion, proximal tumors (6-12 cm from the anal verge) were shown to have a significantly lower local recurrence than those within 6.1 cm from the anal verge (4.2% vs. 37.8%; p <0.001). Low anterior resection performed with double stapling and total mesorectal excision achieved a local recurrence rate of 7.3%. The presence of lymphovascular invasion was the only independent risk factor for local recurrence. A high local recurrence rate was associated with distal cancers (? 6 cm from the anal verge) with lymphovascular invasion. Adjuvant therapy for local control should be considered for this subgroup of patients.

Staple occlusion of the infrarenal aorta: a videoscopic retroperitoneal approach.

PURPOSE: The purposes of this study were to determine whether available laparoscopic stapling devices could be used to interrupt the diseased human aorta, and to develop a videoscopic technique for retroperitoneal exposure and control of the infrarenal aorta in pigs. Our long-term goal is to develop a minimally invasive approach to the treatment of abdominal aortic aneurysms by exclusion and extraanatomic bypass. METHODS: Ten diseased, formalin-preserved human cadaver aortas underwent stapling using a laparoscopic stapling device. The aortas were then pressurized to superphysiologic levels to assess the integrity of the staple line. Ten swine underwent retroperitoneal video-assisted exploration with control and staple occlusion of the aorta and iliac artery. RESULTS: The staple line was complete and remained intact after pressurization in nine of 10 cadaver aortas, despite the presence of complex calcified disease. One aorta had a 2-mm opening through the staple line. Through the left retroperitoneal approach, the infrarenal aorta and left iliac artery could be dissected and controlled. A modified pledgeted technique used for stapling resulted in hemostasis of the staple line and exclusion of flow without injury to adjacent structures. CONCLUSIONS: The diseased human aorta can be occluded using available laparoscopic staplers. These swine experiments demonstrate the feasibility of the retroperitoneal approach for exclusion of infrarenal aortic aneurysms.

[Stenosis caused by mechanical colorectal anastomosis. Technique of plasty].

Stenosis occurs in 1.2 to 4% of the cases after colorectal anastomosis, especially after stapling. Ischaemia may have been favoured in our two cases. Treatment requires endoscopic dilatation or section of a sclerous diaphragm and may entail reconstruction of the anastomosis. The Kraske plasty is a simple and rapid procedure (case n. degree 1) and can be performed via endoluminal access (case n. degree 2) using a linear suture.

Stabilization of high tibial osteotomy with staples.

Patients presenting with painful arthritis of the medial knee compartment with an intact lateral compartment are treated by high tibial valgus osteotomy at our institution. Between 1989 and 1993, 75 high tibial valgus osteotomies were done. Of these, 52 were idiopathic, 22 post-traumatic, and 1 subsequent to an intra-articular infection of the knee. The condition of the lateral compartment was routinely checked arthroscopically. All osteotomies were stabilized with osteotomy staples. This provided immediate stability, allowing partial weight-bearing (15 kg). Because of the simplicity and the low complication rate, we recommend this technique as a suitable treatment for arthritis of the medial condyle of the knee.

Risk factors for pelvic pouch failure.

PURPOSE: This study was designed to identify factors associated with pelvic pouch failure. METHOD: A retrospective review of patients undergoing the pelvic pouch procedure with a minimum of 30 months follow-up was conducted. RESULTS: A total of 551 patients had pelvic pouch procedures from 1981 to 1992. Forty-nine patients (8.8 percent) have undergone pouch excision, and 9 (1.6 percent) have been defunctioned, for 58 (10.5 percent) patients with pouch failure. Cause of failure was leakage from the ileoanal anastomosis (IAA) in 21 (39 percent) patients, poor functional results in 13 (23 percent), pouchitis in 7 (12 percent), pouch leakage in 7 (12 percent), perianal disease in 7 (12 percent), and miscellaneous in 3 (5.2 percent). Nine of 22 patients (41 percent) had pouch failure during the first two years, with 2 of 147 patients (1 percent) having failure during the last two years of the study. The 58 patients whose pouches failed (Group 1) were compared with the 493 patients whose pouches did not fail (Group 2). Handsewn IAA (P < 0.001), tension on the IAA (P < 0.001), use of a defunctioning ileostomy (P < 0.01), a diagnosis of Crohn's disease (P < 0.001), and a leak from the pouch (P < 0.001) or the IAA (P < 0.001) were associated with pouch failure. Pouchitis was not a risk factor. CONCLUSION: The majority of pouch failures were caused by leaks at the IAA. Although the leak rate remained stable, leaks following a stapled anastomosis seemed to have a better prognosis than leaks following a handsewn anastomosis. Experience with the pouch procedure and the management of complications likely plays an important role in decreasing the risk of pouch failure.

Laparoscopic assisted vaginal hysterectomy: one group's experience.

Laparoscopic assisted vaginal hysterectomy (LAVH) has been reported worldwide. We report our experience with LAVH in 51 patients, 23 with the laparoscopic stapling device, 12 with a combination of stapler and bipolar coagulation, and 16 by bipolar coagulation exclusively. No operations were converted to laparotomy, and there were few minor complications. Average operating time was 1 h and 38 min. Hospital stay averaged 2.2 days. Average hospital costs were greater for the stapling devices ($7815.00) compared with bipolar coagulation ($7150.00). Postoperative patient satisfaction was high (96%), with high resolution of the symptoms (94%). We conclude that LAVH is a safe, effective operation in selected cases and may be a valid alternative to abdominal hysterectomy.

Outcome of patients with indeterminate colitis undergoing a double-stapled ileal pouch-anal anastomosis.

INTRODUCTION: The aim of this study was to assess the outcome of patients with indeterminate colitis undergoing double-stapled ileal pouch anal anastomosis. METHODS: A retrospective review of demographic, disease-related, and outcome variables of all patients undergoing double-stapled ileal pouch anal anastomosis from August 1988 to January 2000 was undertaken. All patients were evaluated using the validated American Society of Colon and Rectal Surgeons Fecal Incontinence Severity Index. Patients with familial adenomatous polyposis, those who had undergone pouch revision or had S-configured pouches, and patients with a follow-up of less than three months were excluded from analysis. RESULTS: Three hundred ninety-five patients underwent the double-stapled ileal pouch anal anastomosis; of these 303 patients were included for analysis. The mean duration of follow-up was 40 months. Fifty-six (18.1 percent) had a preoperative diagnosis of indeterminate colitis. Postoperatively, indeterminate colitis was diagnosed in 13 (4.3 percent), mucosal ulcerative colitis in 285 (94 percent), and Crohn's disease in 5 (1.6 percent). The overall complication rate was 37.7 percent, 60 percent, and (30.7) percent in patients with mucosal ulcerative colitis, Crohn's disease, and indeterminate colitis, respectively. Postoperative hemorrhage, abscess, and fistula occurred in 2.4 percent, 6.3 percent, and 3.9 percent, respectively, in patients with mucosal ulcerative colitis, and 0 percent, 15.3 percent, and 7.7 percent, respectively, in patients with indeterminate colitis. Small-bowel obstruction occurred in 8.5 percent, 20 percent, and 7.7 percent of patients with mucosal ulcerative colitis, Crohn's disease, and indeterminate colitis, respectively. Pouchitis occurred in 4.6 percent of patients with mucosal ulcerative colitis but in none of the patients with indeterminate colitis. Dysplasia of the anal transition zone was seen in one patient each with mucosal ulcerative colitis and indeterminate colitis. These patients had consistent follow-up and neither showed any sign of evolution to neoplastic disease. None of the patients with indeterminate colitis had a postoperative diagnosis of Crohn's disease during the follow-up period. Functional outcome was comparable in all three patient groups. CONCLUSION: The outcome of the double-stapled ileal pouch anal anastomosis in patients with indeterminate colitis is similar to that of patients with mucosal ulcerative colitis. Therefore, it is a safe option in patients with indeterminate colitis.

Modified Longo's hemorrhoidectomy.

The Longo technique of stapled hemorrhoidectomy is rapidly gaining world-wide acceptance. However, hemorrhoids with large external components are often left with troublesome skin tags after the Longo technique. In this article we present modifications to the Longo technique that make it easier to perform and provide adequate treatment of hemorrhoids that have a significant external component or skin tags.

Physeal stapling for idiopathic genu valgum.

Adolescent idiopathic genu valgum may cause anterior knee pain, patellofemoral instability, circumduction gait, and difficulty running. The purpose of this study was to evaluate and discuss what we consider to be an ideal treatment protocol using hemiphyseal stapling. We reviewed 76 patients (152 knees) who underwent hemiphyseal stapling for idiopathic adolescent genu valgum and were followed up to maturity. Clinical evaluation included assessment of gait, limb length, alignment, and patellofemoral stability. Radiographic evaluation included measurement of the distal femoral angle (DFA), the anatomic femoral tibial angle (FTA), and the mechanical axis (MA) before stapling, at the time of staple removal, and at skeletal maturity. After stapling, we noted improvement in gait, clinical symptoms, and all radiographic parameters. Our conclusion is that adolescent genu valgum may cause significant symptoms including anterior knee pain and gait problems. Hemiphyseal stapling addresses the anatomic malalignment, alleviating symptoms while offering a high degree of patient satisfaction. It is safe and effective, with no premature physeal closures noted in our series. The procedure, which is well tolerated, obviates the need for corrective femoral osteotomies.

One hundred consecutive cases of video-assisted thoracoscopic surgery for primary spontaneous pneumothorax.

We reviewed our experience on video-assisted thoracoscopic surgery (VATS) from our first 100 cases of primary spontaneous pneumothorax (PSP) performed at our institution from September 1992 to January 1994. Apical bullae were identified in 87% of cases. Mechanical pleurodesis with Marlex mesh was performed on all patients. Excision with endoscopic staple cutter was performed in 69 cases; an endoloop was used in five cases; ablation with an argon beam coagulator (ABC) was done in six cases; excision with endoscopic suturing occurred in seven cases; and mechanical pleurodesis alone was used in 13 cases. The overall median postoperative chest tube duration was 2 days (range 1-25 days) and hospital stay 4 days (range 1-30 days). Complications occurred in 8 cases (8%): 1 wound infection; 1 chest wall bleeding; and 6 persistent air leaks which lasted for more than 10 days (one of which eventually required an axillary thoracotomy for control). Procedure failure with recurrence occurred in three cases (3%) at a mean follow-up of 17 months (range 8-24 months). The ABC group alone was responsible for one recurrence and two persistent leaks. We conclude that with the VATS approach in the treatment of PSP, staple resection of apical bullae is quick and most reliable but costly. Endoloop and hand suturing are applicable to selected patients with small and localized bullae and should be further studied, while our limited experience does not favor ABC as the primary treatment modality.

Intracorporeal rectal stapling following laparoscopic total mesorectal excision: overcoming a challenge.

BACKGROUND: Division of the rectum following total mesorectal excision (TME) using intracorporeal stapling devices is technically difficult due to their width and limited roticulation. More than one cartridge is often required and resultant wedging of the stump may be associated with an appreciable leak rate. METHODS: Three-dimensional reconstruction was performed of CT and MRI images from the lower abdomen of six patients undergoing laparoscopic TME using the Amira software environment. The stapling device was virtually reconstructed by in-house developed software, superimposed over the point of division of the rectum and the site of skin entry identified. RESULTS: The 45 degrees angulation of available roticulating stapling devices precludes perpendicular division of the rectum following laparoscopic TME. The optimal angulation for transverse rectal stapling varied between 62 degrees and 68 degrees . CONCLUSION: A roticulating stapler with minimum angulation of 65 degrees would achieve transverse division of the rectum following laparoscopic TME.

Customized staple fixation in hand and wrist surgery.

Fixation of small bones in the adult and the child's hands remains a challenge. The authors present a technique of bone fixation using customized staples made intraoperatively from K-wires (0.9-1.6 mm in diameter). Their specific purpose was to provide axial alignment and rotational stability for carpal bone fixation and for epiphysiodesis in phalanges. This technique was used in 14 cases (11 adult and three paediatric). No bone shattering, implant breakage, implant loosening or infection occurred. As K-wires are quite malleable, custom sized and shaped staples which follow the bone contours could be made to give a more exact fixation. All cases had satisfactory outcomes, achieving the preoperative objectives of bony fixation. This method is safe, precise and technically easy. It is also relatively cheap and only requires simple, standard instruments.

Arthroscopic anterior cruciate ligament reconstruction using autogenous hamstring tendon graft without detachment of the tibial insertion.

This article describes a modified arthroscopic technique of anterior cruciate ligament reconstruction using quadrupled hamstring tendon graft. The autogenous semitendinosus and gracilis grafts are harvested without detachment of the tibial insertion. To obtain longer grafts, the accessory tibial insertions of the hamstring tendons are dissected. The EndoButton (Acufex Microsurgical, Andover, MA) is used for femoral fixation and two spiked staples are used for tibial fixation in a belt buckle fashion. Then the residual anterior laxity is restored by additional absorbable interference screw fixations. In this technique, more viable graft is obtained and more firm distal fixation is achieved by preservation of the tibial insertion of hamstring tendons.

Endoscopic stapled diverticulotomy: treatment of choice for Zenker's diverticulum.

OBJECTIVE: To evaluate the efficacy and safety of endoscopic stapled diverticulotomy in the treatment of patients with Zenker's diverticulum. STUDY DESIGN: Cohort study. METHODS: Fourteen elderly patients (11 men and 3 women) with Zenker's diverticulum were evaluated in a community hospital setting from July 1996 to November 1999. Before surgery patients had significant dysphagia, regurgitation, cough, or aspiration pneumonia. The common septum between the diverticulum and cervical esophagus was visualized with a Weerda diverticuloscope. While using videoendoscopic monitoring, the septum was divided and the edges simultaneously sealed with a linear endoscopic stapler. Average operative time was 31 minutes. RESULTS: The operation was successfully performed in 11 of 14 patients. In the three unsuccessful cases, one patient's pouch was too small to staple and the other two patients had a septum that was difficult to visualize with the diverticuloscope. There was no significant postoperative morbidity or mortality. Patients started a liquid diet on the first postoperative day and resumed a soft diet a week later. They were usually discharged on the first postoperative day. Most patients reported significant improvement with resolution of dysphagia and regurgitation. CONCLUSIONS: Compared with the traditional open technique, the endoscopic stapled diverticulotomy technique is safe, quick, and effective and requires a shorter length of stay in the hospital. Therefore it has become our treatment of choice for elderly, high-risk patients with a large (>2 cm) hypopharyngeal (Zenker's) diverticulum.

The gastrojejunostomy in laparoscopic Roux-en-Y gastric bypass.

Many techniques for creating the gastrojejunal anastomosis while performing laparoscopic gastric bypass in obese patients have been described. The stapled anastomoses comprise the circular stapler technique, using either a 21- or a 25-mm anvil, and the linear stapler technique. The handsewn anastomosis, which seems to offer some advantages over the mechanical technique, is being performed with increased frequency. The three techniques are described here and discussed in the light of our own experience.

Peptic ulcer/stricture after gastric bypass: a comparison of technique and acid suppression variables.

BACKGROUND: Mason's original animal experiments on the gastric bypass (GBP) showed little acid production in the gastric pouch, a finding confirmed in humans. Despite this, GBP in humans is associated with an incidence of ulcer/stricture (U/S) at the gastrojejunostomy of 3 to 20%, with both acid secretion and staple-line dehiscence considered important risk factors or etiologies. Our series of GBP patients was reviewed to determine what technical or management factors, if any, were associated with U/S. METHODS: All patients undergoing first time GBP at Dartmouth-Hitchcock Medical Center by one surgeon from June 1991 until June 2000 were reviewed. The incidence of U/S as confirmed on upper endoscopy was determined by retrospective chart review. The technique of surgery, frequency of acid suppressive therapy at discharge, postoperative day of U/S diagnosis by endoscopy, length of follow-up with a member of the multidisciplinary bariatric team, and incidence of staple-line dehiscence were tabulated. RESULTS: 158 patients (72% female, mean BMI 53, mean age 42) underwent GBP. Two gastric stapling methods were used to create the gastric pouch: 4-rows (136 patients) and 8-rows (22 patients). No other technical feature was adjusted in the series. The two patient groups were similar in gender, age, and BMI. Acid suppressive therapy at the time of discharge was similar in each group with U/S (4-rows 64% and 8-rows 50%, p = 0.5). U/S developed in 12 (55%) of the 8-row group and in 14 (10%) of the 4-row group (p < 0.001). U/S typically occurred within the first 2 months postoperatively (mean 48 days, SD 40). No patients in our series developed a staple-line dehiscence. CONCLUSION: U/S occur in the first few months following GBP. Twice the number of gastric staple-lines is associated with over five times the incidence of U/S, whereas post-discharge acid suppressive therapy is not predictive of U/S. Thus, a technique performed to decrease the risk of staple-line breakdown was associated with a much higher incidence of U/S. Staple-line dehiscence is not the etiology of this condition. Therefore, U/S after GBP does not appear to be explained by acid injury. We speculate that local, tissue injury related factors may be more responsible, a speculation that invokes a novel pathophysiologic mechanism for U/S formation following gastrojejunostomy.

Arthroscopic management of instability of the shoulder.

Anterior shoulder dislocation in the young athlete may be difficult to treat and, without proper care, usually results in recurrent episodes of instability. By permitting direct visualization of all intraarticular pathology, the arthroscope assists in the diagnosis and helps to determine appropriate therapeutic interventions. Numerous techniques have been developed for arthroscopic reconstruction of unstable shoulders. These can be classified according to the type of fixation employed. The categories include metal devices such as staples or screws, absorbable devices, and suture-based methods, both anterior and transglenoid. An anterior suture anchor method using a new suture passing device known as a Shuttle Relay (Linvatec Corp, Largo, Fla), which allows the surgeon to incorporate non-absorbable mattress sutures in the repair, is described in detail.

Video-assisted thoracoscopic resection of an epiphrenic diverticulum with esophagomyotomy and partial fundoplication.

Videothoracoscopic stapled diverticulectomy with distal esophageal myotomy and partial fundoplasty was successfully done for a 65-year-old woman who had a large, symptomatic epiphrenic diverticulum associated with achalasia. This minimally invasive approach resulted in good symptomatic relief of dysphagia, minimal postoperative pain, a 1-day hospital stay, and early return to normal activity.
