Thoracoscopic bleb resection selectively combined with pleurectomy for complicated spontaneous pneumothorax.

OBJECTIVE: To evaluate the short and long term results of video-assisted thoracoscopic surgery for complicated pneumothorax. DESIGN: Retrospective study. SETTING: General hospital, Linz, Austria. SUBJECTS: 76 consecutive patients with complicated pneumothorax. INTERVENTIONS: 57 patients with primary and 19 with secondary spontaneous pneumothorax underwent video-assisted thoracoscopic surgery. Depending on the findings at thoracoscopy, patients were allocated to have stapled bleb resection (n=29), multiple bleb resection combined with apical pleurectomy (n=40), or apical segmental resection combined with apical pleurectomy (no visible disease on the lung surface, n=7). MAIN OUTCOME MEASURES: Efficacy, morbidity, mortality, and late recurrence rate. RESULTS: No conversions to open thoracotomy were necessary and early lung reexpansion was achieved in all but one patient (99%). There was one postoperative death (1%) and morbidity was 7%, including one persistent air leak and one early recurrence, both of which required thoracotomy. All postoperative complications developed in patients with spontaneous pneumothorax secondary to diffuse bullous emphysema. At a median follow up of 34 months there were 4 ipsilateral pneumothorax recurrences (5%), two of which developed after bleb resection combined with pleurectomy and two after bleb resection alone. CONCLUSION: Video-assisted thoracoscopic surgery was safe and effective for the treatment of complicated spontaneous pneumothorax. It is our procedure of choice for complicated primary spontaneous pneumothorax and is a valuable alternative to open thoracotomy for patients with secondary spontaneous pneumothorax.

The efficacy and side effects of gelatin-resorcinol formaldehyde-glutaraldehyde (GRFG) glue for preventing and sealing pulmonary air leakage.

This study was conducted to examine the efficacy and side effects of gelatin-resorcinol formaldehyde-glutaraldehyde (GRFG) glue, when used for preventing or sealing pulmonary air leakage during lung surgery. Formaldehyde-glutaraldehyde (FG) jelly was prepared by mixing FG fluid with 2.5% carboxymethyl cellulose to increase its viscosity. A GRFG glue-spreading stapler was employed to prevent air leakage from the staple line when cutting emphysematous lung tissue in 26 patients, 25 of whom underwent video-assisted thoracoscopic surgery (VATS) and 1, open thoracotomy. A glue-sealing procedure was employed to stop existing pulmonary air leakage in a further 36 patients, 28 of whom underwent VATS and 8, open thoracotomy. The glue-spreading stapler technique prevented air leakage in all 26 patients (100%), while the glue-sealing procedure for pulmonary air leakage stopped air leakage in 31 of the 36 patients (86%). Two patients who underwent glue sealing for air leakage from a deeply cut lung surface suffered massive pulmonary air leakage on postoperative day (POD) 1 and 6, respectively, and required repeat surgery to suture the lung fistula. A transient fever of 38 degrees-39 degrees developed on POD 7 in 6 of the 62 patients (9.7%), but no other complications were observed. These results demonstrated that GRFG is safe and effective in preventing or stopping pulmonary air leakage in the peripheral lung, but not for stopping air leakage from a deeply cut lung.

Posterior truncal vagotomy and stapling of the anterior stomach wall in 30 patients with duodenal ulcer: acid inhibition, gastric emptying, and endoscopic dye spraying. Prospects for endoscopic vagotomy.

The use of a stapling instrument (TA90) to effect a transection of the anterior gastric wall with posterior truncal vagotomy but preserving innervation to the anterior wall of the antrum for duodenal ulcer is described. The operation resulted in the endoscopic healing of all the ulcers; however, recurrent ulceration was seen in 3 of 25 patients. Basal acid output was reduced from 7.84 (SEM 1.73) to 3.49 (SEM 1.15) mmol/h (t = 2.09, df = 15.7, p = 0.05), while peak acid output was reduced from 38.67 (SEM 3.11) to 19.26 (SEM 2.3) mmol/h (t = 5.01, df = 23.9, p = 0.0000). Solid and liquid gastric emptying studies were performed, and while some delay in solid emptying was seen, only one patient complained of transient gastric stasis. Endoscopic Congo red staining was performed postoperatively and a tongue of innervated mucosa along the lesser curve was seen in each case. The procedure was easily and rapidly performed, and early clinical results are good, with 25 of 30 patients having a good (Visick I) result.

Laparoscopic rectopexy using mesh fixation with a spiked chromium staple.

UNLABELLED: Abdominal rectopexy for patients with rectal prolapse is well suited for performance laparoscopically because no resection or anastomosis is necessary, with potential benefits being a decrease in postoperative pain, better cosmesis, and an earlier return to normal activity. PURPOSE: Objectives of this study were to determine the feasibility of laparoscopic abdominal rectopexy using a solitary spiked chromium staple to fix the mesh to the sacrum and to compare initial results with consecutive previous abdominal rectopexies (historical control study). METHODS: Duration of operation (anesthetic plus surgery), the day a solid diet was first tolerated, day of discharge, and patient morphine requirements in the first 48 hours were documented prospectively for the laparoscopic group and retrospectively from medical records for an open abdominal rectopexy group. RESULTS: Laparoscopic rectopexy group had lower morphine requirements when using patient-controlled analgesia (mean, 38.2 vs. 100.6 mg; P < 0.02), an earlier tolerance of solid diet (mean, 2.7 vs. 5.8 days; P < 0.001), and an earlier discharge from the hospital (mean, 6.3 vs. 11.0 days; P < 0.01). Operating time was longer for the laparoscopic group (mean, 198 vs. 130 minutes; P < 0.001). CONCLUSIONS: Laparoscopic rectopexy is feasible, may have benefits in reducing postoperative pain, and may aid earlier return to normal diet and activity. Given the inherent bias of a historical control study, a randomized controlled study has commenced to confirm these results.

[DST and low/ultralow/colo-anal anastomoses laparoscopically in the treatment of low rectal cancer].

OBJECTIVE: To assess the feasibility and adequacy of double stapling technique (DST) and anal sphincter preservation with laparoscopic approach for low rectal cancer. METHODS: DST and low/ultralow/coloanal anastomoses were performed laparoscopically on 30 patients with low rectal cancer. RESULTS: The 30 laparoscopic DST and low/ultralow/colo-anal anastomoses with anal sphincter preservation were successfully completed, and not one of the cases was converted to open procedures. The operation time was 155 min with the ranges from 110 to 320 min. The operative blood loss was 20 ml with a range between 5 and 80 ml. The time of bowel function restoration and post-operative ambulation was 1-2 days after the operation. 14 patients had postoperative analgesic requirement. The hospital stay varied from 5 to 14 days, averaging 8 days, and there were no intraoperative and postoperative complications in the 30 patients. CONCLUSION: Laparoscopic DST and low/ultralow/colo-anal anastomoses for low rectal cancer is a perspective minimally invasive technique, which is feasible, safe and effective. With the use of this technique, surgeons could accomplish higher rates of sphincter preservation, more accurate autonomic nerve preservation and good micturation with decreased postoperative pain and rapid recovery.

Mechanism of short-term improvement in lung function after emphysema resection.

We prospectively investigated the mechanism of airflow limitation before and after targeted emphysematous resection in 12 consecutively studied adult patients 68 +/- 4 yr of age (mean +/- SD) with very severe COPD undergoing bilateral thoracoscopic stapling techniques. Lung function, static lung elastic recoil, and airway conductance was measured 2 wk before and 5 to 6 mo after surgery. After surgery, there was a significant (p < 0.01) reduction in TLC (9.3 +/- 0.3 [mean +/- SEM] to 7.7 +/- 0.4 L), functional residual capacity, and residual volume. Airway conductance, FVC, and FEV1 (0.7 +/- 0.1 to 1.2 +/- 0.2 L) all improved significantly (p < 0.01). Lung elastic recoil increased markedly at TLC (from 10.3 +/- 0.5 to 14.6 +/- 1.0 cm H20; p < 0.001) as did maximal expiratory airflow in every patient. Analysis of maximal expiratory flow-static elastic recoil pressure curve indicated that conductance of the S segment (Gs) increased from 0.20 +/- 0.03 (mean +/- SEM) to 0.27 +/- 0.03 L/s/cm H20 (p < 0.01), and the critical transmural pressure (Ptm') decreased from 3.1 +/- 0.2 to 2.4 +/- 0.2 cm H20 (p < 0.02). Mean airway conductance increased from 0.14 to 0.22 L/s/cm H20 (p < 0.01). The improvement in maximal expiratory airflow can be primarily attributed to increased lung elastic recoil and its secondary effect on enlarging airway diameter causing increased airway conductance, increased Gs, and decreased Ptm'.

Coordinated activity of the new "rectum" and anal sphincter after sphincter-saving resection of the rectum for colitis or carcinoma.

PURPOSE: The aim of this study was to determine whether coordinated activity exists across a stapled enteroanal anastomosis. METHODS: Twenty-nine patients were studied for a median of one year after complete excision of the rectum and stapled enteroanal anastomosis; 12 patients underwent low anterior resection with coloanal anastomosis for carcinoma, and 17 patients underwent restorative proctocolectomy with ileoanal anastomosis. RESULTS: Maximum anal resting pressures were slightly lower after coloanal anastomosis than after ileoanal anastomosis [median range, 56 (11-60) cm H2O, cf 69 (40-107) cm H2O, P = NS]. During distention of the neorectum, anal sphincter pressures at 2.5, 1.5, and 0.5 cm from the anal verge were significantly lower after coloanal anastomosis compared with after ileoanal anastomosis (P < 0.01 at each station). The volume of neorectal distention required to produce maximal inhibition of the anal sphincter was significantly less after coloanal anastomosis at 50 (range, 20-60) ml of air than after ileoanal anastomosis at 240 (range, 100-420) ml of air (P < 0.01). Minor fecal leakage and urgency of bowel action were significantly more common after coloanal anastomosis (P < 0.01). CONCLUSION: Alterations in the dynamic response of the anal sphincter to distention of the neorectum may explain why the clinical results were better after ileal pouch-anal anastomosis than after coloanal anastomosis.

Modern stapled Longo procedure vs. conventional Milligan-Morgan hemorrhoidectomy: a randomized controlled trial.

BACKGROUND AND AIMS: Postoperative pain is the most distressing sequela of conventional hemorrhoidectomy. A modern alternative of circumferential mucosectomy has been proposed to reduce the pain in this procedure. PATIENTS AND METHODS: This controlled trial included 80 patients with second to fourth degree hemorrhoidal disease operated on over a 2-year period. The patients were randomly allocated to undergo either the stapled Longo procedure (group 1) or Milligan-Morgan hemorrhoidectomy (group 2) under epidural anesthesia. The operating time, postoperative pain scores at 3, 6, 12, and 24 h, analgesic consumption, hospital stay, and complication rate were recorded. At follow-up the outcome and patient satisfaction were evaluated. RESULTS: The mean operating time in group 1 was shorter than in group 2, postoperative pain scores at all time points and the mean epidural morphine requirement was lower, and mean hospital stay was shorter. The complication rate did not differ (three cases of postoperative bleeding in group 1 and two cases in group. At follow-up no recurrence or complains were recorded except three cases of mild incontinence (one in group 1 and two in group 2). The patients in group 1 (95%) were more satisfied than in group 2 (89%). CONCLUSION: The Longo procedure is thus a simple, safe, and effective method that entails less postoperative pain, more satisfaction, and shorter hospital stay than the standard Milligan-Morgan hemorrhoidectomy.

Comparison between open hand-sewn, laparoscopic stapled and laparoscopic computer-mediated, circular stapled gastro-jejunostomies in Roux-en-Y gastric bypass in the porcine model.

BACKGROUND: In this porcine survival model, we compared laparoscopic computer-mediated flexible circular stapled (SurgASSIST) gastro-jejunostomies in Roux-en-Y gastric bypass (RYGBP) to open hand-sewn (HS) and laparoscopic end-to-end (EEA) anastomosis. METHODS: RYGBP was performed in 15 pigs. Depending on the technique used to create the gastro-jejunostomy, the pigs were divided in 3 groups. In group A, a standard two-layer hand-sewn anastomosis were performed. In group B and C, gastro-jejunostomies using EEA (B) or SurgASSIST (C) were attempted. Operation time, intraoperative technical failure, postoperative anastomotic leakage, and necropsy results were measured. RESULTS: 14 pigs survived surgery. One leakage from the gastro-jejunostomy was detected intraoperatively in group B. There was no evidence of leakage postoperatively from the proximal gastro-jejunostomy in any groups. No statistical difference was found between the groups concerning the operation time or the diameter and degree of healing of the anastomosis. CONCLUSION: We found the SurgASSIST system safe for performing gastro-jejunostomies in laparoscopic RYGBP. There were no anastomotic failures intra- or postoperatively. At necropsy, there was no evidence of anastomotic stricture or delayed healing processes.

Defunctioning loop ileostomy and stapled side-to-side closure has low morbidity.

INTRODUCTION: Low pelvic anastomoses are associated with a high leak rate. Therefore, defunctioning loop ileostomies are being increasingly fashioned to protect against the consequences of a leak. However, the reported complication rates of such stoma creation and closure is between 5.7-69%. AIMS: To determine the outcome associated with construction and side-to-side closure of loop ileostomies in one specialist unit. PATIENTS AND METHODS: Data were obtained from a computer audit and case note analysis. RESULTS: Between 1994 and 1998, 71 patients (41 M, 30 F) with a median age of 51 years (range 19-88 years) had a loop ileostomy constructed for: (i) 26 ileoanal pouches; (ii) 36 left colonic and rectal resections; and (iii) 9 for other reasons. Side-to-side stoma closure was achieved using a GIA linear stapler through a parastomal incision. The median hospital stay following stoma creation was 12 days (range 7-63 days) and stoma closure was 7 days (range 6-16 days). The median time to closure was 140 days (range 10-790 days). There were no ileostomy-related deaths. There were 10 (13.8%) ileostomy-related complications, 4 following creation and 6 following closure. CONCLUSIONS: Loop ileostomy is easy to create and close and is associated with a low morbidity. Therefore, we recommend a defunctioning ileostomy as a procedure of choice for temporary faecal diversion for complex colorectal surgery.

Vertical banded gastroplasty by laparoscopic technique in the treatment of morbid obesity.

From October 1993 through May 1994, 38 consecutive morbidly obese patients underwent a laparoscopic vertical banded gastroplasty (VBG). During the operation a gastric window was made by a 25-mm circular stapler; and the vertical staple line, establishing the gastric pouch, was constructed by using a 60-mm, four-row linear stapler. The outflow stoma was reinforced by a Gore-Tex band and calibrated to have an internal diameter of 9 mm. Three patients had to be converted to open surgery during the initial laparoscopic procedure because of insufficient operative access. Another three patients had to be reoperated during subsequent postoperative courses, one laparoscopically to reinforce a vertical staple line defect caused by a transected nasogastric tube, another because of an open reoperation during the first postoperative day for a rupture in the vertical staple line, and, finally, a patient was reexplored because of the present of postoperative fever with a left-sided pleuropneumonia and subphrenic accumulation of fluid. However, during the operation no leakage or any other local complications were detected. The subsequent postoperative courses were uneventful in all these patients. Compared with the reference group comprising the latest consecutive 17 obese patients operated with open VBG before the introduction of the laparoscopic technique, the laparoscopy group had less postoperative pain and had mobilization sooner. In the latter group, we recorded an improved respiratory status during the early postoperative period, as reflected by increased oxygen saturation and peak exspiratory flow rates as well as a lower body temperature. In conclusion, laparoscopic VBG is technically feasible and can be safely performed. Our early postoperative experiences suggest that these patients have a shorter and less cumbersome postoperative recovery period compared with conventionally operated obese patients. The long-term follow-up of these patients will determine whether these initial advantages of the laparoscopic approach are corroborated by comparable effects on weight control.

Randomized comparison between stapled hemorrhoidopexy and Ferguson hemorrhoidectomy for grade III hemorrhoids in Taiwan: a prospective study.

PURPOSE: Short-term and mid-term outcomes of stapled hemorrhoidopexy (SH) were compared with those for Ferguson hemorrhoidectomy (FH) for treating hemorrhoids. MATERIALS AND METHODS: Patients with prolapsed hemorrhoids were randomized into two groups treated with SH (N = 300) and FH (N = 296) at Chang Gung Memorial Hospital at Chiayi in Taiwan between January 2002 and December 2004. The outcomes of the procedures were evaluated postoperatively (short-term, i.e., intra-/postoperative conditions, hospital stay, pain intensity scoring, time off work, and procedure-related morbidity) and over a follow-up period of minimum 18 months (mid-term, i.e., relapse of prolapse and/or bleeding, anal stricture, anal sepsis, and the acceptability of the procedures to the patients). RESULTS: SH was superior to FH in operative time, intraoperative blood loss, postoperative pain intensity, and return to work. Based on telephone interviews over the follow-up period, most patients who received SH appreciated the procedure better than those with FH. CONCLUSIONS: This study confirms that SH generates less postoperative suffering, less time off work, and more complete resolution of primary symptoms associated with hemorrhoids in the mid-term follow-up than FH.

Stapled ileal pouch-anal anastomosis with resection of the anal transition zone.

We assessed the outcome of stapled ileal J-pouch-anal anastomosis with intersphincteric resection of the anal transition zone in 83 consecutive patients with ulcerative colitis (n = 71) or familial adenomatous polyposis (n = 12). There was no postoperative mortality. Two patients (2.4%) required permanent ileostomy for manifestation of unsuspected Crohn's disease. Major postoperative complications consisted of pelvic sepsis, anastomotic leakage, and pancreatitis with 3.6% each. Both, frequency of bowel movements and degree of continence improved with time. Two years after takedown of the diverting ileostomy 45 patients with ulcerative colitis and 12 with familial adenomatous polyposis were assessed with a frequency of bowel movements of 5.6 +/- 2 and 3.2 +/- 1 per 24 h, respectively (P < 0.05). At this time none of them had major daytime or nighttime incontinence. Minor incontinence was reported by 9% and 14% of the patients with ulcerative colitis during day-time and night-time, respectively. The patients with familial adenomatous polyposis demonstrated better results, without day-time seepage and intermittent nocturnal seepage in only 9%. It is concluded that direct ileal J-pouch-anal anastomosis is a safe procedure with excellent functional results for patients with ulcerative colitis and familial adenomatous polyposis.

Stapled transanal rectal resection versus stapled anopexy in the cure of hemorrhoids associated with rectal prolapse. A randomized controlled trial.

PURPOSE: A remarkable incidence of failures after stapled axopexy (SA) for hemorrhoids has been recently reported by several papers, with an incomplete resection of the prolapsed tissue, due to the limited volume of the stapler casing as possible cause. The stapled transanal rectal resection (STARR) was demonstrated to successfully cure the association of rectal prolapse and rectocele by using two staplers. The aim of this randomized study was to evaluate the incidence of residual disease after SA and STARR in patients affected by prolapsed hemorrhoids associated with rectal prolapse. METHODS: Sixty-eight patients were selected on the basis of validated constipation and continence scorings, clinical examination, colonoscopy, anorectal manometry, and defecography and randomized: 34 underwent a SA and 34 a STARR operation. The operated patients were followed-up with clinical examination, visual analog scale for postoperative pain, a satisfaction index, and defecography. RESULTS: At a mean follow-up of 8.1+/-2.0 and 7.9+/-1.8 months for the SA and STARR groups, respectively, the incidence of residual disease was significantly higher in the first group (29.4 vs 5.9 in the STARR group, p=0.007), while a significantly lower incidence of residual skin-tags was found after STARR (23.5% vs 58.8 after SA, p=0.03). All patients with residual disease showed prolapsed tissue over half the length of the anal dilator at the time of the operation. Operative time and incidence of transient fecal urgency were significantly higher in the STARR group (with p=0.001 and 0.08, respectively), while SA was followed by a significantly higher incidence of poor results at the overall patient satisfaction index (p=0.04). No significant differences were found in hospital stay, operative complications, postoperative pain, time to return to normal activity, continence, and constipation scores. All the defecographic parameters significantly improved after STARR, while SA was followed only by a trend to a reduction of rectal prolapse. CONCLUSIONS: STARR provides a more complete resection of the prolapsed tissue than SA in patients with association of prolapsed hemorrhoids and rectal prolapse with equal morbidity and significantly lower incidence of residual disease and skin-tags. The anal dilator can be used for selecting the surgical technique.

Ileoanal pouch operation: long-term outcome with or without diverting ileostomy.

HYPOTHESIS: Avoiding a diverting ileostomy does not influence the long-term overall morbidity and functional outcome of patients after ileoanal pouch operation (IAP). DESIGN: All patients undergoing IAP were prospectively entered into a database, and those undergoing operation from October 1, 1989, through January 31, 1996, were contacted by mail questionnaire. SETTING: Tertiary referral center. PATIENTS: One hundred thirty unselected sequential patients. INTERVENTIONS: The IAP was completed by a stapled method without diverting ileostomy, provided the patient agreed, and there were no other complicating factors. MAIN OUTCOME MEASURES: Need for reoperation, fecal leakage, pouch frequency, ability to defer evacuation, pouchitis, and overall quality of life. RESULTS: Of 102 patients (78.5%) who initially underwent IAP without diverting ileostomy, 10 (9.8%) developed an anastomotic leak and required a diverting ileostomy. Additional surgery was required in 12 (9.2%) of the 130 patients for bowel obstruction and in 3 (2.3%) for pouch excision. Two patients died of unrelated causes, leaving 125 functioning pouches (96.2%). Questionnaires were completed in 111 (88.8%) of the 125; 75 patients (67.6%) reported perfect continence for gas and stool, 10 patients (9.0%), regular nighttime leakage, and 24 patients (21.6%), occasional fecal leakage. Pouch evacuation frequency (+/-SD) per 24 hours was 7.8+/-2.4 (range, 4-12), and 95.5% of patients could defer pouch evacuation. Of the 111 patients, 42.3% reported pouchitis, with 7.2% receiving long-term antibiotic therapy. Of the patients, 74.8% reported total satisfaction, and 84.7% regarded themselves as being in perfect health. CONCLUSION: Long-term outcome after IAP remains favorable with or without diverting ileostomy.

Circumferential mucosectomy with stapled proctopexy is a safe, effective outpatient alternative for the treatment of symptomatic prolapsing hemorrhoids in the elderly.

BACKGROUND: Circumferential mucosectomy with stapled proctopexy (CMSP) was first introduced in 1993 as a less painful and highly effective alternative to traditional operative hemorrhoidectomy. Although CMSP has many advantages over traditional hemorrhoidectomy, some authorities and insurers continue to regard it as an inpatient procedure and others have been slow to adopt this progressive technique. This study documents the safe and effective outpatient nature of this procedure. METHODS: From December 2001 through August 2002, 33 patients with mucosal prolapse and prolapsing internal hemorrhoids were treated using circumferential mucosectomy with stapled proctopexy as outpatients at an ambulatory surgery center. Fourteen (42%) patients were treated using local anesthesia with intravenous sedation, 18 (55%) chose spinal anesthesia, and general anesthesia was used in one patient. Patients were evaluated postoperatively by telephone at 1 and 2 weeks, and seen in clinic at 4 weeks. RESULTS: One patient (3%) required an emergency department visit for minor postoperative bleeding. None of our elderly patients required emergency department evaluation and none reported significant complications. Four patients (13%) required urinary catheter placement prior to discharge from the surgery center due to urinary retention. One patient (3%) developed an uncomplicated urinary tract infection, which resolved with antibiotic treatment. Two patients were seen earlier than 4 weeks at the surgeon's request; one was immunocompromised from chemotherapy for metastatic carcinoid, and one reported persistent pain during initial telephone follow-up. No complications were identified in either patient, and no additional complications have been noted to date. CONCLUSIONS: CMSP is a safe, effective, time-efficient procedure for patients with mucosal prolapse and prolapsing hemorrhoids that can be performed safely in the ambulatory surgery center setting. Age is not a limiting factor in selecting patients for this safe outpatient procedure.

Can a meta-analysis answer the question: is mucosectomy and handsewn or double-stapled anastomosis better in ileal pouch-anal anastomosis?

Although ileal pouch-anal anastomosis (IPAA) is the procedure of choice for polyposis and ulcerative colitis with medically refractory disease or dysplasia, controversy exists concerning whether mucosal preservation with double-stapled (DS) IPAA is superior to mucosectomy and handsewn (HS) IPAA anastomosis for postoperative function. Prospective studies have shown no statistically significant differences. The use of meta-analysis can strengthen statistical power by combining the data from related studies. A meta-analysis was performed to determine whether there was a significant difference in functional and manometric outcome between HS-IPAA and DS-IPAA. Prospective, randomized studies were identified using a literature search. Functional outcome variables included number of normal continence, minor incontinence, nocturnal evacuation, the ability to discriminate flatus from stool, and antidiarrheal medication. Manometric outcomes included postoperative resting and squeeze anal pressures. Four prospective, randomized trials were identified. Of the 184 total patients, the HS-IPAA group included 86 patients (48 men and 38 women) and the DS-IPAA group included 98 patients (49 men and 49 women). There were no significant differences in functional outcome between HS-IPAA and DS-IPAA. In addition, there was no significant difference in sphincter resting and squeeze pressures between the two patient groups. This meta-analysis demonstrates that DS-IPAA offers no advantage in functional or manometric outcome when compared with HS-IPAA.

Significant symptomatic relief after transoral endoscopic staple-assisted treatment of Zenker's diverticulum.

BACKGROUND: Zenker's diverticulum is associated with characteristic symptoms of progressive dysphagia and regurgitation. As most patients are elderly, the perioperative risk is usually high. We report our clinical experience with the transoral endoscopic staple-assisted method, including a thorough assessment of the symptomatic relief achieved by the procedure. METHODS: 46 consecutive patients (29 m, 17 f) with a median age of 61 years (range, 37-96 years) were treated between 1997 and 2002. The symptoms and their frequency were registered. The follow-up consisted of clinical and radiographic investigations. RESULTS: The median size of the diverticulum was 4 cm (range, 2-12 cm). Transoral treatment was successful in 39 patients; in 7 cases (15.2%) a switch to open surgery was required. The median operating time was 30 min (range, 10-150 min). Mortality rate was nil, while morbidity was 7.7%. The median duration of the postoperative hospital stay was 5 days (range, 1-65 days). After a median follow-up of 11 months (range, 1-40 months), 5 patients had been reoperated on endoscopically due to clinical recurrence. Clinical symptoms were significantly reduced (dysphagia of liquids p <or= 0.0001, dysphagia of solids p <or= 0.001, regurgitation p <or= 0.001). CONCLUSION: Our results confirm that minimal invasive treatment of Zenker's diverticulum is a safe method and provides significant symptomatic relief.
