Laparoscopically assisted subtotal colectomy.

A technique for laparoscopic total resection of the colon performed in six patients is reported. The diseased colon was separated from the mesocolon and the greater omentum by electrocoagulation and sharp dissection. The mesenteric vessels were divided using an Endo GIA stapling device (AutoSuture, France). The whole colon was removed after transection of the rectum and extraction through a right minilaparotomy. A primary stapled end-to-side ileorectal anastomosis was performed through the anus under laparoscopic guidance. This technique can be applied to cases involving a variety of benign lesions of the entire bowel or multifocal small malignant colonic neoplasms with a decrease in patient morbidity and shorter inpatient period.

Stapled hemorrhoidectomy: present status.

AIM: To evaluate cost-effectiveness of stapled hemorrhoidectomy comparing its results with conventional technique. SOURCE OF DATA: We retrospectively analyzed the MEDLINE data basis from 2000 to 2004 studying randomized clinical trials which compared pain intensity, recovery period, return to work and occurrence of anal incontinence, in addition to postoperative complications and costs evaluation between stapled and conventional hemorrhoidectomy during different periods of follow-up. CONCLUSIONS: Stapled hemorrhoidectomy provides lesser postoperative pain and earlier return to work than conventional hemorrhoidectomy. However, its efficacy could not be determined, since rigorous prospective and randomized clinical trials with long-term follow-up periods and large size samples are not available at this time.

Re-resection of the short cicatricial stenosis of colorectal anastomoses with EEA stapler.

Following 245 stapled anastomoses reoperation was necessary in 4 cases because of non-tumourous stenoses. In each of the 4 cases re-resection was performed according to authors' method, with EEA stapler, without the mobilisation of the rectum. The method is considered suitable for non-tumourous anastomotic stenoses involving short rectal segments.

Endoscopic full-thickness resection of the stomach: an experimental approach.

BACKGROUND: Endoluminal endoscopic resections of the gastrointestinal (GI) tract have had increasing significance in recent years. Except for the extraperitoneal part of the rectum, endoscopic resections are restricted to the mucosal and submucosal layer to preserve the integrity of the GI tract wall. METHODS: The SurgAssist is the first flexible stapling device consisting of a 2,000-mm-long flexible shaft and a stapling magazine that can be positioned intraluminally and used with a remote control. To prove the principle, we investigated the endoluminal application of an endoscopically assisted and intraluminally visualized full-thickness resection of the gastric wall in a pilot study of three pigs and a series of three human exenterates. RESULTS: Full-thickness resection of the gastric wall in pigs can be performed with the SurgAssist flexible stapling device from an endoluminal access. However, due to the small lumen of the esophagus, the simultaneous transesophageal introduction of the stapler shaft and gastroscope is not possible in pigs. The same procedure in three human exenterates showed that the simultaneous introduction of the flexible stapler and a standard gastroscope could be achieved without damaging the esophageal wall. Full-thickness resections of up to 4 x 4 cm were carried out with the use of two or three stapler magazines. The resulting sutures were found to be airtight upon endoscopic inflation of the stomach. CONCLUSION: The clinical use of the SurgAssist intraluminal stapling device for endoscopic full-thickness resection of the gastric wall seems applicable for lesions in suitable locations of the stomach. Gastrointestinal stroma tumors and T1 tumors of the lower gastric corpus and antrum region are possible indications.

Long-term effects of stapled haemorrhoidectomy on internal anal function and sensitivity.

BACKGROUND: Stapled haemorrhoidectomy is gaining wide acceptance but there is still some concern about the risk of injury to the internal anal sphincter (IAS). IAS function and morphology, and anal canal sensitivity were studied prospectively in patients undergoing this operation. METHODS: Twenty patients (11 women; mean age 43 years) with stage III haemorrhoids entered the study. All underwent preoperative anorectal manometry, rectoanal inhibitory reflex (RAIR) testing and three-dimensional transanal ultrasonography. A test of anal sensation was administered to evaluate ability to discriminate between air and warm water. All the investigations were repeated 6 months after the operation. RESULTS: The mean(s.d.) maximal resting pressure was 87(30) mmHg before surgery and 81(20) mmHg afterwards (P not significant). The maximal squeeze pressure did not change after operation (178(43) versus 174(60) mmHg). The RAIR showed the same features in 19 of 20 patients before and 18 of 20 after operation. Three-dimensional ultrasonography demonstrated no changes in the width of the IAS (mean(s.d.) 2.1(4) mm before and 2.1(3) mm after surgery). The ability of the anal mucosa to discriminate air from warm water improved in five patients. Continence scores did not differ significantly after 6 months. CONCLUSION: Stapled haemorrhoidectomy does not affect the function and morphology of the IAS in the long term. The sensitivity of the anal canal can improve in patients with preoperative sensory impairment.

Hemidouble stapling for esophagogastrostomy during laparoscopically assisted proximal gastrectomy.

In esophagogastrostomy during laparoscopically assisted proximal gastrectomy, some problems have occurred; the main ones being reflux esophagitis and the technical difficulty in anastomosis. We have had good results with a hemidouble stapling technique; the center rod of circular stapler is pierced through the left end of the staple line of the stomach. The longest distance from the pylorus to the esophagogastrostomy can be fired in this position. The distance is longer, so alkaline esophagitis is rarer. When the center rod is pierced through the anterior or posterior gastric wall, the operator may be worried about ischemia of the area surrounded by the linear stapler and circular stapler. In hemidouble stapling, an ischemic area is not created at all structurally. Any surgeon can perform a reproducible anastomosis because the place pierced with the center rod is fixed. This technique is easy and safety to operate via minilaparotomy.

The use of bovine pericardial strips on linear stapler to reduce extraluminal bleeding during laparoscopic gastric bypass: prospective randomized clinical trial.

BACKGROUND: A prospective comparison was conducted of extraluminal bleeding following gastric transection with or without staple-line reinforcement by dehydrated bovine pericardium (Peri-Strips Dry--PSD) during laparoscopic Roux-en-Y gastric bypass (LRYGBP). METHODS: From January 2001 to September 2003, 98 consecutive morbidly obese patients underwent LRYGBP. Patients were randomly allocated to 2 groups according to the use (Group A, n= 50) or not (Group B, n= 48) of Peri-Strips Dry. In both groups, mortality, intra- and postoperative early and late complications, operating-time, number of hemostatic clips used, blood transfusion and any specific event directly related to the prosthetic material were prospectively evaluated. Data were expressed as mean +/- SD except as otherwise indicated. Statistical analysis was done by means of Student t-test and Fisher exact test. P-value cut off for statistical significance was set at 0.05. RESULTS: Intra- and postoperative mortality were absent. Intra-operative methylene blue test was positive in 6/48 (12.5%) of Group B patients (P<0.001). Overall laparotomic conversion was 3/98 patients (3.1%). One/48 Group B patient was converted because of unsatisfactory exposure and one for linear stapler misfire. One/50 Group A patients was converted for short gastric vessels bleeding during dissection. No patients were re-operated or transfused because of extraluminal bleeding. Mean number of clips used was significantly lower in Group A patients (5 vs 23, P<0.001). The operating-time was significantly less in Group A patients (120+/-60 vs 220+/-100 minutes, P<0.01). CONCLUSIONS: Gastric staple-lines reinforced with Peri-Strips Dry result in a significant reduction in the number of Endo-clips used and prevent bleeding. A dry operating field was obtained, and operating-time was significantly reduced. No adverse events could be related to the use PSD.

Transhiatal stapled esophagojejunostomy without a pursestring suture in patients with previous gastric resection.

Previous gastric resection complicates alimentary tract reconstruction after esophagectomy. Colonic interposition is the standard conduit in this circumstance, but has substantial mortality and morbidity, especially important when treatment goals are to provide effective alimentation and minimize hospital stay. This report details the technique of a transabdominal, intrathoracic, stapled esophagojejunostomy created without a pursestring suture, which was used to reconstruct the esophagus in 3 patients who had previously undergone partial gastrectomy. This technique avoids both colon interposition and thoracotomy, thereby minimizing the associated complications.

Distal pancreatectomy: is staple closure beneficial?

BACKGROUND: Appropriate closure of the pancreatic remnant after distal pancreatectomy remains controversial. Data on distal pancreatectomy were reviewed to evaluate the effectiveness of staple closure compared with suture closure. METHODS: Thirty-three patients underwent distal pancreatectomy between January 1994 and December 2001. They were subdivided according to the method of closure of the distal pancreatic stump: the staple group comprised 10 patients and the suture group comprised 23 patients. Charts were reviewed for the method of closure of the distal stump as well as for the serum and urinary amylase level, mortality and morbidity. RESULTS: In the staple group, no patient developed a pancreatic fistula, whereas in the suture group, eight patients (33.3%) developed a pancreatic fistula (P = 0.0353). The serum amylase level (mean +/- SD) on the first postoperative day was 185 +/- 71 IU/L in the staple group and 499 +/- 461 IU/L in the suture group (P = 0.0413). CONCLUSION: Staple closure by means of a Powered Multifire Endo GIA 60 is a simple, quick and safe alternative to the standard suture closure technique, as it reduces the incidence of pancreatic fistula.

Treatment by VATS of giant bullous emphysema: results.

OBJECTIVE: In selected patients with giant bullous emphysema GBE and in those with specific complications, surgery may be the treatment of choice. METHODS: In the period January 1993-February 1996 we performed 34 VATS treatments in 29 patients affected by GBE. There were 22 (76%) males and 7 (24%) females, with a mean age of 54 years (range 24 74). In 23 cases, a pneumothorax (PNX) was present at admission, while 6 patients were treated by choice. Altogether. we performed 23 resections of sessile bullae (type 2 of Reid) by using a linear endoscopic stapling device (Endo-path 35 and 45 mm) and 11 ligatures of pedicled bullae (type 1 of Reid) by loop (Endo-loop 'PDS'). The mean number of charges for every treatment was 8 (range 4-21). The largest bullae were perforated and deprived of incarcerated air. They were then twisted on the axis perpendicular to the base in order to improve the manoeuvrability of the lesion and favour the correct placement of the Endo-path or Endo-loop. GBE was bilateral in 7 cases: one of these was treated bilaterally in the same surgical stage, other 4 were treated by staged operations. RESULTS: We experienced two conversions to open thoracotomy (one sessile giant bulla inside the fissura; 1 case of strong tuberculous pleural adhesions). Two patients, underwent a second operation by open thoracotomy because of a prolonged air leak. We have two peri-operative deaths, both to respiratory failure. Altogether, in 23 out of 29 (79%) cases VATS was effective and the mean hospital stay was 6 days (range 3-16). At a mean follow up of 16 months (range 1-36) no recurrence of PNX was observed. CONCLUSIONS: VATS may be considered as a suitable surgical technique to approach GBE and, in most cases, it is effective.

[Physiological and clinical outcome of open and closed hemorrhoidectomy compared with stapling method according to long].

AIM OF STUDY: The aim of the study was to evaluate and inaugurate a new method for the treatment of hemorrhoidal disease with the usage of a stapling device (Long's method). PATIENTS: The study spanning two years (September 1999 to June 2001), included 97 hospitalized patients aged 19-75 years, 42 (43.3%) female and 55 (56.7%) male, exhibiting symptoms and signs of stage III hemorrhoidal disease. The patients were divided into three groups: (a) 35 patients treated with open hemorrhoidectomy for stage II hemorrhoidal disease; (b) 30 patients treated with closed hemorrhoidectomy for stage III hemorrhoidal disease; and (c) 32 patients treated for stage III hemorrhoidal disease by a stapling device, i. e. Long's method. RESULTS: Study results showed no statistically significant differences between either open or closed hemorrhoidectomy and Long's method in the following parameters: urinary retention, early bleedings during the first 48 hours, late bleedings, incontinence, anal stenosis, and relapses. Statistically significant differences between the groups of patients treated with either open or closed hemorrhoidectomy and those treated with Long's method were recorded in the following parameters: healing time, subjective feeling of pain, pain pro rata to quantity, and use of analgesics. CONCLUSION: Hemorrhoidectomy by Long's method is an ideal surgical procedure because it allows to realize to goals set on implementing new therapeutic methods: to achieve healing without relapse, to reduce postoperative pain, anal stenosis and incontinence after hemorrhoidectomy, to preserve the physiology of the anal canal, and to familiarize less skilled proctology surgeons with the simplicity of the method.

Hand-assisted laparoscopic autoaugmentation gastrocystoplasty.

BACKGROUND: Autoaugmentation gastrocystoplasty has been previously performed successfully. This set of experiments was conducted to determine the feasibility of performing autoaugmentation gastrocystoplasty laparoscopically. METHODS: Hand-assisted laparoscopic autoaugmentation gastrocystoplasty was performed on 15 mongrel dogs. The surgery was carried out with two 10-mm trocars and a 6-cm Pfannenstiel incision. The gastric wedge, supplied by the right gastroepiploic artery, was resected with two applications of an endoscopic gastrointestinal anastomosis (GIA) stapler. The pedicle was demucosalized, and the anastomosis to the bladder was completed through the Pfannenstiel incision. RESULTS: All of the dogs were successfully treated laparoscopically and were eating at 48 h. There was no evidence of anastomotic leak dehiscence at the gastric resection staple line. CONCLUSION: Hand-assisted laparoscopic autoaugmentation gastrocystoplasty can be performed successfully in dogs. This operation may offer a superior alternative to standard bladder autoaugmentation procedures in children suffering from congenital bladder disorders.

PPH03 stapled hemorrhoidopexy: our experience.

BACKGROUND: Stapled hemorrhoidopexy is an established treatment for hemorrhoidal disease. We evaluated our experience with stapled hemorrhoidopexy using the new Procedure for Prolapse and Hemorrhoids (PPH03) Proximate HCS hemorrhoidal circular stapler (Ethicon Endo-Surgery). METHODS: We retrospectively reviewed clinical data for 238 patients who had undergone stapled hemorrhoidopexy in our department over a 2-month period. Patients were followed-up for a median of 3.5 weeks (range, 1-11 weeks) and were analyzed for complications and resolution of symptoms. RESULTS: The hemorrhoids treated were third- and fourth-degree, as well as second degree (after failure of other therapies). Mean duration of surgery was 12.7 minutes (range, 5-20 minutes) and the majority of patients was treated with an ambulatory procedure. Most patients were discharged within 6 hours after surgery. On follow-up, 3.7% of patients had minor complaints after surgery. Technically, the new PPH03 stapler device has a quickclose knob, which allows rapid opening and closing. The closed staple height of 0.75 mm increases staple line compression on tissue and key blood vessels, hence minimizing bleeding. Prior to this, stapled hemorrhoidopexy was done using the PPH01 device. CONCLUSIONS: Stapled hemorrhoidopexy using the new PPH03 stapler is a safe, short and effective procedure in the management of hemorrhoids. It can be done in the ambulatory setting and patients have few postoperative complications.

Randomized prospective trial comparing ileal pouch-anal anastomosis performed by excising the anal mucosa to ileal pouch-anal anastomosis performed by preserving the anal mucosa.

OBJECTIVE: The purpose of the study is to compare the results of ileal pouch-anal anastomosis (IPAA) in patients in whom the anal mucosa is excised by handsewn techniques to those in whom the mucosa is preserved using stapling techniques. SUMMARY BACKGROUND DATA: Ileal pouch-anal anastomosis is the operation of choice for patients with chronic ulcerative colitis requiring proctocolectomy. Controversy exists over whether preserving the transitional mucosa of the anal canal improves outcomes. METHODS: Forty-one patients (23 men, 18 women) were randomized to either endorectal mucosectomy and handsewn IPAA or to double-stapled IPAA, which spared the anal transition zone. All patients were diverted for 2 to 3 months. Nine patients were excluded. Preoperative functional status was assessed by questionnaire and anal manometry. Twenty-four patients underwent more extensive physiologic evaluation, including scintigraphic anopouch angle studies and pudendel never terminal motor latency a mean of 6 months after surgery. Quality of life similarly was estimated before surgery and after surgery. Univariate analysis using Wilcoxon test was used to assess differences between groups. RESULTS: The two groups were identical demographically. Overall outcomes in both groups were good. Thirty-three percent of patients who underwent the handsewn technique and 35% of patients who underwent the double-stapled technique experienced a postoperative complication. Resting anal canal pressures were higher in the patients who underwent the stapled technique, but other physiologic parameters were similar between groups. Night-time fecal incontinence occurred less frequently in the stapled group but not significantly. The number of stools per 24 hours decreased from preoperative values in both groups. After IPAA, quality of life improved promptly in both groups. CONCLUSIONS: Stapled IPAA, which preserves the mucosa of the anal transition zone, confers no apparent early advantage in terms of decreased stool frequency or fewer episodes of fecal incontinence compared to handsewn IPAA, which excises the mucosa. Higher resting pressures in the stapled group coupled with a trend toward less night-time incontinence, however, may portend better function in the stapled group over time. Both operations are safe and result in rapid and profound improvement in quality of life.

Stapling of knees with valgus deformity in children with juvenile chronic arthritis.

OBJECTIVE: Leg length discrepancy and excessive knee valgus are potential complications of juvenile chronic arthritis of the knee. The aim of the present study was to evaluate retrospectively the safety and efficacy of temporary stapling of the knee epiphyses in management of valgus deformities of the knee in children with JCA. METHODS: Medical data of the patients with temporary epiphyseodesis due to knee valgus deformity (KVD) were studied. 177 knees in 112 patients were found with sufficient data for evaluation. Patient documents and radiographs of these patients were evaluated. RESULTS: Mean age at the time of operation was 8 years (range: 2 - 17) in 19 males and 93 females. The patients are predominantly affected by aggressive polyarticular disease. Preoperative mean valgus angle was 11 degrees (IQR: 9, 14) and at staple removal 4 degrees (IQR: 2, 5). In 120 of 177 knees (68% [95% CI: 61 - 74], p < 0.001) the physiological angle (3-8 degrees) was reached. Median time of stapling was 10 months (IQR: 8, 13). Five reversible and one irreversible (3% [95% CI: 2 to 7]) major complications were documented among the 177 stapled knees. CONCLUSION: Temporary epiphyseal stapling enables flexible correction of KVD in children with JCA. Low complication rate encourages the use of the method. Prompt follow-up is, however, important in avoing excess over-correction to varus.

Transabdominal extensive oesophagogastric devascularization with gastro-oesophageal stapling in the management of acute variceal bleeding.

BACKGROUND: Operation is required for patients with portal hypertension who have failed to respond to emergency sclerotherapy for control of acute variceal bleeding. This study evaluates the role of transabdominal extensive oesophagogastric devascularization combined with gastro-oesophageal stapling for control of acute variceal bleeding in patients with portal hypertension of different aetiologies. METHODS: Transabdominal extensive oesophagogastric devascularization combined with gastrooesophageal stapling was performed in 65 patients (28 with cirrhosis, 17 with non-cirrhotic portal fibrosis and 20 with extrahepatic portal venous obstruction) in whom emergency endoscopic sclerotherapy, and/or pharmacotherapy and balloon tamponade had failed. The Sugiura procedure was modified to minimize operating time and to reduce the operative difficulties due to oesophageal wall necrosis after sclerotherapy. RESULTS: The operative mortality rate was higher in patients with cirrhosis (P = 0.0003); sepsis was the leading cause of death (in nine of 18). A high mortality rate (12 of 15) was seen in patients with Child grade C cirrhosis. Control of bleeding was achieved in all patients. The procedure-related complication rate was 17 per cent with a 6 per cent oesophageal leak rate; four of 47 surviving patients developed oesophageal stricture. During a mean follow-up of 33 months, residual varices, recurrent varices and rebleeding were seen in three, two and three of 47 survivors. CONCLUSION: Transabdominal extensive oesophagogastric devascularization combined with gastrooesophageal stapling is an effective and safe procedure for control of acute variceal haemorrhage with satisfactory long-term control, especially in patients without cirrhosis and low-risk patients with cirrhosis.

One-stage thoracoscopic oesophagectomy: ligature intrathoracic stapled anastomosis.

Thoracoscopic oesophagectomy is usually performed in stages and intrathoracic oesophagogastric anastomosis often requires mini-thoracotomy or extension of the thoracoscopic incisions. This paper describes a new technique whereby such an operation could be completed in one stage and the need to extend the thoracoscopic incisions is obviated.
