Oncological outcome of ultra-low anterior resection with total mesorectal excision for carcinoma of the lower third of the rectum: Comparison of intrapelvic double-stapled anastomosis and transanal coloanal anastomosis.

BACKGROUND/AIMS: The purpose of this study was to determine whether the type of ultra-low anterior resection (intrapelvic double-stapled anastomosis or transanal hand-sewn coloanal anastomosis) with total mesorectal excision for primary adenocarcinoma of the lower third of the rectum affects survival and recurrence after curative surgery. METHODOLOGY: This retrospective study included 112 patients who underwent curative surgery achieved by ultra-low anterior resection in combination with either intrapelvic anastomosis using a double-stapling technique (DST group; n=82) or transanal hand-sewn coloanal anastomosis (CAA group; n=30). Univariate and corrected (multivariate regression) analyses were used to evaluate data. Median follow-up was 51.2 months for patients alive at the conclusion of this study. RESULTS: Disease-free and disease-specific survivals, and the frequency and location of recurrence after surgery did not differ between the two types of operations. Multivariate analyses showed that the type of operation was not a significant independent variable in predicting disease-free survival or in the development of both local and distant recurrences after surgery. Tumor-related factors (stage or histologic grade) were significant predictors of oncological outcome. CONCLUSIONS: The type of ultra-low anterior resection (DST or CAA) did not affect survival and recurrence after curative resection for carcinoma of the lower third of the rectum.

Anal canal inflammation after ileal pouch-anal anastomosis. The need for treatment.

UNLABELLED: One technique used during restorative proctocolectomy to prevent loss of continence involves preservation of the anal canal. This technique retains a small amount of colonic mucosa and transitional mucosa that may become inflamed or develop dysplastic or neoplastic changes. PURPOSE: This study was designed to determine the presence and severity of anal canal inflammation and the need for treatment. METHOD: Records of 217 patients with mucosal ulcerative colitis who underwent restorative proctocolectomy with a stapled ileal pouch-anal anastomosis without anal mucosectomy from 1987 through 1990 were retrospectively reviewed. RESULTS: Anal canal inflammation was evident on both endoscopy and biopsy in 48 patients (22.11 percent); 18 patients (8.29 percent) had a normal ileal pouch (9 had symptoms; 5 required topical treatment), and 30 patients (13.82 percent) had associated ileal pouch inflammation (23 with symptoms requiring systemic treatment because of pouchitis; 10 patients had concomitant topical treatment). CONCLUSION: Symptomatic inflammation of the retained mucosa occurred in 32 (14.7 percent) patients. Nine (4.1 percent) patients had inflammation of the anal canal alone, and 23 (10.6 percent) had pouchitis in addition. The need for treatment occurred in 28 (12.9 percent) of the total ((2.3 percent) patients with anal canal inflammation and 23 (10.6 percent) with anal canal inflammation plus pouchitis).

Suction versus water seal after thoracoscopy for primary spontaneous pneumothorax: prospective randomized study.

BACKGROUND: The objectives of the study were to review our experience of video-assisted thoracoscopic apical pleurectomy and to evaluate whether suction or water seal is superior in the postoperative treatment of primary spontaneous pneumothorax. METHODS: One hundred consecutive patients undergoing thoracoscopy for primary spontaneous pneumothorax from January 1995 to December 1999 were prospectively randomly assigned after surgery to receive suction or water seal to their chest tubes after a brief period of suction. RESULTS: There were 50 patients in each group. The two groups were evenly matched for age and operation performed. The method of management was stapling of an identified bleb or apex of the upper lobe and apical pleurectomy. Postoperative prolonged air leak longer than 5 days occurred in 8 patients (8%), 7 in the suction group and 1 in the water seal group (p = 0.03). The mean duration of chest tube days was lower in the water seal group (2.7 days) than in the suction group (3.8 days; p = 0.004). The mean hospital stay in the water seal group was 3.7 days and in the suction group it was 4.8 days (p = 0.004). Mean follow-up was 48 months (range, 30 to 60) for all patients. Pneumothorax recurred in 2 patients (2%). The recurrences occurred in the first year. CONCLUSIONS: Video-assisted thoracoscopic apical pleurectomy is effective and safe for treating primary spontaneous pneumothorax. Placing chest tubes on water seal after a brief period of suction shortens the duration of chest tube placement and hence the hospital stay.

A low-pressure rectosigmoid pouch created by side-to-side anastomosis with a stapling technique and sigmoid colon intussusception as an antireflux procedure.

OBJECTIVE: To assess a new procedure of urinary diversion after cystectomy for bladder cancer. PATIENTS AND METHODS: Thirty-two patients (14 women and 18 men, mean age 54 years, range 35-70) treated by radical cystectomy for bladder cancer underwent urinary diversion using a new technique. After mobilization of the sigmoid colon, the splenic flexure and the upper rectum, two adjacent colotomies were made to complete a stapled side-to-side anastomosis, with intussusception and implantation of the ureters between the layers of the intussusceptum. Two ureteric stents (8F) were brought out through the iliac fossa, and a rectal tube introduced through the anus and the intussusception to the proximal colon. The reservoir was assessed by urodynamic studies, using the anorectal perfusion catheter. RESULTS: Twenty-eight patients were continent day and night, with mild soiling in the remaining four at night. Complications included a urinary fistula in three patients and a fecal fistula in one; all were treated conservatively. Metabolic complications occurred in only two patients. CONCLUSION: The pouch created has a low pressure, a high capacity and provides effective continence. Surgery remains adequately radical, by removing the prostate and the membranous urethra. The implanted ureters between the layers of the intussusceptum provided an effective antireflux mechanism and markedly improved kidney function. The intussusception prevents reflux of the pouch contents into the proximal colon and minimizes metabolic complications. The technique needs neither colostomy nor small intestinal manipulations.

Common bile duct repair with titanium staples. Comparison with suture closure.

BACKGROUND: Vascular Closure Staple (VCS) clips made of titanium were initially developed for microvascular anastomoses with little experience of their use in larger tubular structures. This study compares VCS clips and sutures in the closure of supraduodenal choledochotomy. METHODS: In nine pigs, two longitudinal incisions of the common bile duct (CBD) were randomly assigned to closure with 4-0 interrupted polyglactin sutures or VCS clips. RESULTS: Clip closure was significantly faster (116 +/- 28 vs 581 +/- 88 s). All nine CBDs were patent and without signs of calculus formation after 3 months. Clip closure resulted in slightly less narrowing of the duct lumen and thinner scar at the repair site. At histological examination, all 18 incisions had healed without signs of fistula formation or marked fibrosis. CONCLUSIONS: Choledochotomy closure with VCS clips results in as good or better wound healing than suture closure, with a comparable degree of narrowing. The time required for clip closure is only about one-fifth that of suture closure.

Sphincter preservation in rectal cancer. Technical considerations for coloanal anastomosis and J-pouch.

Most patients with midrectal cancer undergo a sphincter-preserving operation using modern bowel stapling techniques. In patients with bulky tumors or unfavorable pelvic anatomy, however, abdominoperineal resection with permanent colostomy may be performed for technical reasons, not based on oncologic clearance needs. In addition, low-lying tumors treated initially with preoperative chemoradiation are often downstaged, increasing the opportunity for restorative procedures. Treatment by total proctectomy and peranal sutured coloanal reconstruction fulfills the need for adequate oncologic clearance and satisfactory bowel function. Sharp pelvic dissection with removal of the entire rectal mesentery, adequate mobilization of the left colon, and precise anastomotic technique are required for optimal results. Creation of a colon J-pouch increases the capacity of the reconstructed rectum and greatly reduces the time required for functional adaptation in the postoperative period. Although irregular evacuation and other minor problems can persist, permanent colostomy is avoided, and patient satisfaction is high. For cancers of the middle and distal rectum, total proctectomy with coloanal reconstruction is an important treatment option that can improve quality of life without compromising cancer treatment.

Midterm results of thoracoscopic surgery for pulmonary metastases especially from colorectal cancers.

Indications for thoracoscopic metastatectomy remain controversial because not all metastatic tumors may be detected without the manual palpation that is possible with thoracotomy. However, the accuracy (92%) of preoperative lung imaging in patients with one or two lesions led us to re-evaluate thoracoscopic metastatectomy with patient survival as the primary end point. Thoracoscopic wedge resection using an endoscopic stapling device or video-assisted thoracic surgery (VATS) lobectomy was performed in patients with one or two pulmonary metastases. Thoracoscopic resection was performed in 27 patients with 22 solitary lesions and 5 patients with two lesions. The primary tumors were colorectal cancer (15), testicular cancer (3), osteosarcoma (2), and seven other histologies. In 5 of 27 patients (18.5%) a thoracoscopic operation was converted to a VATS procedure, which requires minithoracotomy to identify metastasis primary by digital palpation. The 3-year survival rate for colorectal cancer patients who underwent thoracoscopic resection was 56.4%, in comparison to 48.6% in historical control thoracotomy patients (n = 16). There was no statistically significant difference between the two groups. Thoracoscopic resection of one or two colorectal cancer lung metastases results in a survival rate similar to standard thoracotomy, and thereby provides an acceptable alternative to this more invasive approach.

Anastomotic leak after double-stapled low colorectal resection.

PURPOSE: Anastomotic leaks after double-stapled low anterior resection were associated with a number of factors related to patient condition, level of anastomosis, and variety of surgery-related and antitumor therapy-related factors. This retrospective analysis of a group of patients with consistent length of rectal stump was undertaken to determine the risk factors of anastomotic leak after low colorectal resection related to surgery and to intraperitoneal chemotherapy. METHODS: A group of 165 patients treated with surgery only, surgery with early postoperative intraperitoneal chemotherapy, and surgery with hyperthermic intraoperative and early postoperative intraperitoneal chemotherapy. All patients underwent surgery that used the double-stapled technique with transection of the rectum through its middle third. In univariate and multivariate analysis, the relationship between anastomotic leak rate and extent of colon resection, length of residual colon, presence of left colon, and type of applied treatment was studied. RESULTS: With a full length of residual colon, leak rate was 1 percent but increased progressively with the extent of proximal colon resection. Removal of the left colon was associated with the 2.7 odds ratio for anastomotic disruption. Leak rate after surgery only was 6 percent; surgery with normothermic intraperitoneal chemotherapy was 5 percent; and surgery with heated intraperitoneal chemotherapy was 20 percent. CONCLUSIONS: In this group of patients with consistent length of residual rectum, the incidence of anastomotic disruption was related to extent of proximal colon resection. Anastomotic integrity was not compromised by normothermic intraperitoneal chemotherapy. Hyperthermic intraperitoneal chemotherapy was associated with high leak rate only when extensive resection of the colon was performed. Variables other than extent of rectal excision are important in causing a leak of colorectal anastomosis.

[Total gastrectomy and viscerosynthesis].

A retrospective study of 134 total gastrectomies performed between 1982 and 1992 was conducted with regular follow-up. There were 96 males and 38 women (mean age 66.66 years, range 27-82). The indication for total gastrectomy was malignant tumour (n = 115), mostly adenocarcinoma (79.1%, 91/115) with 7 cases of stump degeneration after partial gastrectomy (5.2%) and benign lesions (n = 19), mostly gastric ulcers. Gastrectomy was associated with node dissection in 53 cancer cases (47.8% 53/115) and dissection of neighbouring organs in 16 patients. Y anastomosis with circular mechanical suture was performed in 78 cases (62.9%) with pre-stapling in 30 (38.5%). Operative mortality was 8.2% (11/134). The oesophagealjejunal disunion occurred in 7/133 patients (5.3%) including two fatal cases. Early reoperation was necessary in 10.5%. Long-term follow-up for 2 to 12 years in 119 patients gave the following data. For malignant tumours: 5-year survival rate 10.1% (n = 8), recurrence an anastomosis 6.3% (n = 5), distant recurrence 28.2% (n = 21). For all patients sequellae were: reflux oesophagitis 8.1% (n = 10), stenosis of the anastomosis 7.3% (n = 9) requiring late reoperation in 2. The quality of life was considered satisfactory by 28.57% (n = 8) and good in 39.29% (n = 11). These results were compared with those reported in the literature and led to the conclusion that the general view as to the gravity of gastrectomy should be reconsidered in light of the progress in viscerostapling.

Anterior rectal wall excision for endometriosis using the circular stapler.

BACKGROUND: Endometriosis involving the rectum is rare but is associated with significant symptoms that are best relieved by resection of the involved segment of rectum. Resection necessitates either a segmental or anterior rectal wall excision with sutured closure. Application of a circular stapling device allows an alternative technique to resect endometriosis in this area. METHOD: Following laparoscopic ablation of endometriosis elsewhere in the pelvis, the rectum must be mobilized around disease present on the anterior rectal wall. This will involve lateral and anterior extraperitoneal rectal dissection; the latter dissection mobilizing the vagina from the rectum by a sufficient length necessary to allow imbrication of the diseased area. Insertion of a circular stapler per anus allows the diseased area to be imbricated into the stapler, resulting in simultaneous excision and closure of the anterior rectal wall. RESULTS: Thirty patients with anterior rectal wall endometriosis, estimated at <2 cm in diameter and not involving > one-third of the total circumference of the rectum, have undergone successful management using this technique. Morbidity occurred in four patients, with one patient requiring further surgery. CONCLUSIONS: Laparoscopic disc excision of deposits of endometriosis involving the anterior rectal wall can be safely performed utilizing the circular stapler without the need for open surgery, and with low morbidity.

Safety and efficacy of staple-mediated femoral arteriotomy closure: results from a randomized multicenter study.

BACKGROUND: Mechanical closure of percutaneous femoral arteriotomies following catheter based procedures remains problematic. METHODS: The EVS closure device is the first to utilize a staple to effect arteriotomy closure and was compared to manual compression following sheath removal in a 362 patient randomized (2:1 to device) multicenter trial. As pre-specified, one half of the patients underwent coronary intervention. RESULTS: Time to hemostasis was significantly reduced in the EVS group for both diagnostic (3.3 +/- 2.6 vs. 19.3 +/- 5.7 minutes; p < 0.001) and interventional procedures (5.5 +/- 5.1 vs. 22.3 +/- 9.9 minutes; p < 0.0001). Time to ambulation was similarly reduced in the EVS group following diagnostic (2.4 +/- 3.3 vs. 6.0 +/- 5.2 hours; p < 0.001) and interventional procedures (3.4 +/- 4.5 vs. 7.6 +/- 7.0 hours; p < 0.001). The incidence of major complications was similar between the EVS and manual compression groups at discharge (0.4% vs. 1.7%; p = NS) and at 30 day follow-up (0.4% vs. 2.5%; p = NS). CONCLUSION: Compared to manual compression, the EVS device provides a safe and effective method of femoral artery closure.

Flavonoids to reduce bleeding and pain after stapled hemorrhoidopexy: a randomized controlled trial.

INTRODUCTION: Control of postoperative symptoms is of paramount importance in ambulatory surgery. This trial was conducted to evaluate whether a micronized purified flavonoid fraction (MPFF) (Detralex((R))) reduces postoperative bleeding, pain and consumption of analgesics after ambulatory stapled hemorrhoidopexy, as reported in trials after classic hemorrhoidectomy. Phlebotropic activity, protective effect on the capillaries and anti-inflammatory properties of this drug have been reported in several studies. METHODS: Sixty-three patients with third-degree hemorrhoids had ambulatory stapled hemorrhoidopexy under spinal anesthesia in the period of one year. The patients were randomized, with 30 receiving Detralex 500 mg (2 tablets 3 times daily for 5 days after the operation) and 33 forming the control group. The patients were asked to daily self-assess the presence of blood on defecation, degree of pain and consumption of analgesics for the first week after the operation. RESULTS: There was no significant difference between the two groups in duration of presence of blood, degree of pain or analgesics requirement. No major complications, such as bleeding requiring transfusion or hospitalization, sepsis, anal stenosis or urgent defecation, were noted in the follow-up period. There were no side effects from Detralex treatment. DISCUSSION: In our study we could not demonstrate any positive effect of prescribing flavonoids after stapler hemorrhoidopexy. This procedure may not be sufficiently aggressive and is associated with too few postoperative complications to show any protective influence of flavonoids.

Long-term results after stapled haemorrhoidopexy for third-degree haemorrhoids.

BACKGROUND: Stapled haemorrhoidopexy (SH) is associated with low postoperative pain but, when performed for advanced piles, carries high recurrence rates. The aim of our study was to assess our long-term results after SH for third-degree haemorrhoids. METHODS: A total of 126 consecutive patients (67 men and 59 women) with third-degree haemorrhoids underwent SH in our unit between 1998 and 2002. Of these, 120 (95.2%) were followed up in the outpatient department after a median interval of 61.5 months (range, 38-84 months). RESULTS: During the postoperative period, 7 patients (5.8%) experienced pain for 5-12 days, which was treated with oral analgesia. Seven patients (5.8%) experienced gas incontinence and one of them also reported soiling; the incontinence subsided within 2-8 weeks. Recurrence of the haemorrhoidal disease occurred in 8 patients (6.6%). CONCLUSIONS: SH is a safe, low-pain and, in the long-term, effective technique for the treatment of third-degree haemorrhoids.

A comparison of the mechanical strength of two stapled anastomosis techniques for equine small intestine.

OBJECTIVE: To compare bursting strength, time of construction, and cost of a closed one-stage, stapled functional end-to-end jejunojejunostomy (FEE) with a stapled side-to-side jejunojejunostomy (STS). STUDY DESIGN: Experimental, randomized block design. ANIMALS: Seven adult horses without gastrointestinal disease. METHODS: The jejunum was isolated, and three FEE, three STS, and three control segments were created in each horse using a randomized block design. Anastomosis time was recorded. The intraluminal pressure at failure and mode of failure were recorded. Length at failure was measured on digitized images. Bursting pressure (BP), bursting wall tension (BWT), anastomosis time, and cost were compared. RESULTS: Control jejunal segments were stronger (P < or = .0001) in bursting strength and bursting wall tension (P < or = .0001) than either anastomosis type; no difference was found between anastomosis types for either variable. Functional end-to-end jejunojejunostomy was significantly quicker and less costly than STS (P < or = .0001). CONCLUSIONS: Mechanically there were no significant differences between the FEE and STS techniques. The FEE technique maintained the physiologic direction of peristalsis of the segments, required less tissue manipulation, and was faster and more economical to create. CLINICAL RELEVANCE: The FEE is a clinically viable technique.

Functional outcome in handsewn versus stapled ileal pouch-anal anastomosis.

Eighty-eight of 119 patients who underwent ileal pouch-anal anastomosis for ulcerative colitis were evaluated. Forty patients had a handsewn anastomosis (Hs) with mucosectomy, and 48 had a stapled anastomosis (St). In each patient, we evaluated operative, morphologic, functional, and manometric features. The results in the Hs and St groups were similar when the anastomosis was within 1 cm of the dentate line. In particular, there was no correlation between the type of anastomosis and the number of bowel movements in a 24-hour period, the presence of the urge to defecate, and the use of antidiarrheal drugs. Leakage was significantly higher in the Hs group, even when the anastomosis was less than 1 cm from the dentate line. Pouchitis was more frequent in the Hs group, and, within this group, among those with a short distance between the anastomosis and the dentate line. No correlations were found between the presence of columnar epithelium or active colitis in the mucosa below the anastomosis, the functional outcomes, and the incidence of pouchitis.

Pharyngeal reflux after gastric pull-up esophagectomy with neck and chest anastomoses.

OBJECTIVE: Pharyngeal reflux after a gastric pull-up esophagectomy may cause aspiration. This study evaluates acid exposure to the esophageal remnant and to the pharynx after gastric pull-up esophagectomy and evaluates the impact of additional dissection of the esophagus that is necessary for neck anastomoses versus no neck exploration and proximal chest anastomoses. METHODS: Forty-seven patients had circular stapled anastomoses in the apex of the right chest (n = 27 patients) or manually sutured neck anastomoses (n = 20 patients). A 24-hour double-pH study with the probes placed 3 cm cranial and 3 cm distal to the cricopharyngeal muscle was performed. The percent time pH less than 4 was registered 3, 6, and 12 months after the operation. RESULTS: Mean acid exposure to the proximal pH probe ranged between 0.2% and 0.96% and between 1.45% and 6.5% to the distal pH probe during the 3 measurements. Acid exposure was always lower to the proximal than to the distal probe (P =.001). Patients with neck anastomoses had increasing acid exposure to the distal (P =.023) and proximal (P =.002) pH probes during the study year, whereas patients with chest anastomoses had similar acid exposure. CONCLUSIONS: Acid exposure to the esophageal remnant and to the pharynx increased during the first postoperative year in patients with neck anastomoses but not in patients with proximal chest anastomoses. The results suggest a less favorable acid clearance in patients with the neck approach.

Application of a NiTi staple in the metatarsal osteotomy.

Thirty-six metatarsal osteotomies using internal fixation of a shape memory metal compression staple for hallux valgus were performed in 21 women with a mean age of 42.3 years (30-66 years). The time for return to light work averaged 19.0 days, and to full work and normal walk 41.2 days after the operation. Twenty patients (35 feet) had complete relief from pain. Only in one foot, the pain was transferred under the second metatarsal head. The appearance of the feet was apparently improved and the width of the forefeet was decreased by a mean of 0.90 cm after the operation. Radiographic analysis of feet showed that all osteotomies united, and the average angle of hallux valgus was improved from 31.2 degrees to 16.3 degrees and the mean intermetatarsal angle from 12.0 degrees to 6.4 degrees. No external fixation of plaster splintage was needed and the distal fragment during healing of the osteotomy was stable. The time of bone healing was shortened and patients were allowed to bear weight at an early time.

Role of transperineal Doppler and ultrasound in evaluating anal sphincter injury after stapled haemorrhoidopexy.

The stapler treatment first described by Longo is considered by some authors to be a good technical solution for mucohaemorrhoidectomy. The aim of the present prospective study was to assess the function and morphology of the internal and external anal sphincters preoperatively and one month after surgery by means of a clinical examination, anorectal manometry and transperineal ultrasound. Ten patients (6 M, 4 F) underwent rectal mucosal prolapsectomy according to Longo. Anoscopy, anorectal manometry and transperineal ultrasound were performed in all patients preoperatively and again one month after surgery. The thickness and integrity of the internal and external anal sphincters were ascertained and colour Doppler was performed to assess the presence, quantity and size of any haemorrhoid swellings. All anatomical specimens underwent histological examination in search of smooth muscle fibres. Anorectal manometry revealed no postoperative sphincter tone defects. Transperineal ultrasound detected no postoperative sphincter lesions and the presence of venous swellings (always present at preoperative colour Doppler) never persisted at postoperative follow-up. The mean follow-up was 52.7 days (range: 31-151). Transperineal ultrasound proved useful in demonstrating the lifting of the mucohaemorrhoid prolapse within the ampulla of the rectum one month after surgery. The Longo procedure, in our albeit limited experience, caused no sphincter lesions.
