Long-term results after stapled hemorrhoidopexy: a prospective study with a 6-year follow-up

BACKGROUND

Stapled hemorrhoidopexy was introduced in 1998 as a new technique for treating advanced hemorrhoidal disease. Despite a clear perioperative advantage regarding pain and patient comfort, literature reviews indicate a higher recurrence rate for stapled hemorrhoidopexy than for conventional techniques.

OBJECTIVE

Our aim was to present long-term on the use of this technique.

DESIGN

Observational study.

SETTING AND PATIENTS

Consecutive patients with hemorrhoid prolapse treated at a regional surgical center from May 27, 1999, through December 31, 2003.

INTERVENTION

Stapled hemorrhoidopexy with accompanying resection of residual hemorrhoidal nodules if necessary.

MAIN OUTCOME MEASURES

Standardized patient questionnaire regarding satisfaction, resolution of symptoms, and performance of further interventions.

RESULTS

Of 257 patients (82 female, 175 male, mean age 53 ± 13 years) undergoing stapled hemorrhoidopexy, follow-up data were available for 224 patients (87.2%) with a mean duration of 6.3 ± 1.2 years. Of these, 195 patients (87.1%) were satisfied or very satisfied with the operation outcome; 19 patients (8.5%) were moderately satisfied; and 10 (4.5%) were not satisfied. Regarding preoperative anal symptoms, complete relief was observed in 179 patients (80.6%) for prolapse, 172 (77.5%) for bleeding, 139 (85.3%) for mucus discharge, 139 (78.5%) for burning sensation, and 115 (75.5%) for itching. Considering all recorded symptoms, 194 patients (86.6%) reported absence and or an improvement at follow-up. Twelve patients (5.4%) reported newly developed incontinence in the sense of urge symptoms; 42 patients out of 51 patients (82.4%) with preexisting incontinence reported an improvement. Local or topical retreatment (ointment, suppositories, sclerotherapy) was performed in 48 patients (21.4%). Reoperation for residual or newly developed hemorrhoidal nodules was needed in 8 patients (3.6%).

LIMITATIONS

Lack of a comparative group.

CONCLUSION

Our long-term results show that this strategy for stapled hemorrhoidopexy can achieve a high level of patient satisfaction and symptom control, with a low rate of reoperation for recurrent hemorrhoidal symptoms.

Transanal haemorrhoidal dearterialization (THD) for selected fourth-degree haemorrhoids

BACKGROUND

Traditional treatment of fourth-degree haemorrhoidal disease (HD) is conventional haemorrhoidectomy and is frequently associated with significant pain and morbidity. In recent years, the use of transanal haemorrhoidal dearterialization (THD) for the treatment of HD has increased. The procedure aims to decrease the arterial blood flow to the haemorrhoids. Moreover, since a rectal mucopexy to treat the prolapsing component has become part of the THD technique, this treatment is also indicated for more advanced HD. The aim of this study was to assess the possible role of THD in the treatment of fourth-degree HD.

METHODS

All patients with non-fibrotic fourth-degree HD were offered the THD procedure with mucopexy. Excision of skin tags was added to THD and mucopexy, when needed. A specific score was used to assess HD severity, ranging from 0 (no HD) to 20 (worst HD). The mean preoperative score was 18.1 ± 1.8.

RESULTS

Thirty-five consecutive patients (mean age 50.4 ± 13.8 years; 19 men) with fourth-degree HD were prospectively enroled. An average of 6 arteries were identified and transfixed. Mucopexy was achieved with a 3-6 sector plication of rectal mucosa. Mean operating time was 33 ± 12 min. No intraoperative complications were recorded. Postoperative morbidity included 3 (8.6%) haemorrhoidal thromboses (1 requiring surgery) and 2 (5.7%) episodes of bleeding (1 requiring surgical haemostasis). Five patients (14.3%) had urinary retention requiring catheterization. At a median follow-up of 10 months (range 2-28 months), symptoms had resolved or significantly improved in 33 (94%) patients. Nine patients (25.7%) reported irregular bleeding, 3 patients (8.6%) mild anal pain, 4 patients (11.4%) transient anal burning and 4 patients (11.4%) tenesmus. Ten patients (28.6%) experienced some degree of residual prolapse, significant only in 2 (5.7%) who required further surgery. There was no anorectal stenosis, and no faecal incontinence was reported. At a median follow-up of 10 months, the symptomatic score was 2.5 ± 2.5 (P < 0.005).

CONCLUSION

Transanal haemorrhoidal dearterialization seems to be a safe and effective treatment for fourth-degree HD providing a significant improvement of symptoms for the majority of patients. When present, persisting symptoms are mostly transient, occasional or limited in severity, and only a very few patients require further intervention. Larger series and longer follow-up to further assess the role of THD in this challenging group of pts.

A submucosal fecal mass as the complication of stapled hemorrhoidopexy: A case report

Despite the early encouraging results and safety profile of hemorrhoidopexy, several serious complications have been reported including rectal perforation, retroperitoneal sepsis, pelvic sepsis and rectovaginal fistulas. The recent article is the report of the case of a 30 year old woman, with a submucosal mass which was palpable in the anterior rectum. She had undergone a stapled hemorrhoidopexy due to a 2nd degree internal prolapsed hemorrhoid three years previously. Operation was planned to identify the nature of the mass and a cylindrical impacted 4 cm × 2 cm fecal mass was excised. The recent finding seems to be the first one being reported in this issue.

Long-term outcome of hybrid surgical approach of video-assisted minithoracotomy sleeve lobectomy for non-small-cell lung cancer

BACKGROUND

The aim of this study was to evaluate the technical feasibility and safety of a hybrid surgical approach of video-assisted minithoracotomy (hybrid VATS) sleeve lobectomy for non-small-cell lung cancer (NSCLC), using success rate as the primary end point.

METHODS

Between February 1996 and December 2006, patients with bronchogenic tumors were prospectively registered to undergo hybrid VATS sleeve resection in a single institution. Hybrid VATS involved performing the main procedures via rib spreading and minithoracotomy using a monitor and direct vision. A successful procedure was defined as a patient who had a sleeve lobectomy via hybrid VATS without conversion to thoracotomy and without significant perioperative morbidity or mortality.

RESULTS

A total of 148 patients (108 men and 40 women; median age = 58 years) who underwent hybrid VATS sleeve lobectomy for NSCLC were identified in our database. The median duration of the successfully completed procedures was 190 min (range = 145-305 min). The median length of time of chest tube in place was 3 days (range = 1-12 days). Hybrid VATS sleeve lobectomy was performed successfully in 134 of 148 patients for a success rate of 90.5%. The median follow-up period was 65.1 months (range = 34.5-154.8 months). The overall 5-year disease-free survival and overall survival of all patients were 36.7% (95% CI = 27.9-45.5%) and 54.2% (95% CI = 44.8-63.6%), respectively.

CONCLUSION

Hybrid VATS sleeve lobectomy is feasible for selected patients with NSCLC in specialized centers.

Clinical and pathological features of splenic metastases of colorectal carcinoma: an analysis of three cases

AIM: To study the clinicopathological features and diagnosis of splenic metastases of colorectal carcinoma.

METHODS: The clinical data for three patients with splenic metastases of colorectal carcinoma were retrospectively analyzed to investigate the clinical features, methods of diagnosis and treatment, and prognosis of the disease.

RESULTS: A definite diagnosis was achieved preoperatively by PET/CT in one patient. Two patients were initially diagnosed with splenic abscess. Splenectomy was performed in two patients, and exploratory laparoscopy in one patient. One patient died 2 wk after operation, and the other two patients survived for 2 and 6 years, respectively.

CONCLUSION: Splenic metastases of colorectal carcinoma are a rare disease that is frequently misdiagnosed. Imaging examination is helpful in diagnosing splenic metastases of colorectal carcinoma. Patients with splenic abscess should be suspected of having concomitant colorectal carcinoma. Long-term survival can be achieved by splenectomy in colorectal carcinoma patients with isolated splenic metastasis.

Effects of Aloe vera cream on posthemorrhoidectomy pain and wound healing: results of a randomized, blind, placebo-control study

OBJECTIVE

Aloe vera is an herbal medicine, which has wound healing effects in burn injury. This study assessed the effects of Aloe vera cream in reducing postoperative pain, postdefection pain, and its promotion of wound healing after open hemorrhoidectomy.

DESIGN

A prospective, randomized, double-blind, placebo-controlled trial was conducted comparing the effects of a cream containing Aloe vera versus a placebo cream on posthemorrhoidectomy pain. The study preparations were applied by patients to the surgical site 3 times per day for 4 weeks after hemorrhoidectomy. Pain was assessed with a visual analog scale immediately postoperatively and at hours 12, 24, and 48 after surgery and at weeks 2 and 4. Wound healing was examined and evaluated at the end of 2 and 4 weeks. The use of analgesics was recorded.

RESULTS

Forty-nine (49) patients were randomly assigned to receive aloe (n = 24) or placebo (n = 25). Patients in the topical aloe cream group had significantly less postoperative pain at hours 12, 24, and 48 hours and at 2 weeks. Aloe cream reduced the pain after defecation in 24 and 48 hours postsurgery (p < 0.001). Wound healing at the end of the second postoperative week was significantly greater in the aloe group compared with the placebo group (p < 0.001). Patients required fewer additional analgesics posthemorrhoidectomy (p < 0.001).

CONCLUSIONS

Application of Aloe vera cream on the surgical site is effective in reducing postoperative pain both on resting and during defecation, healing time, and analgesic requirements in the patients compared with the placebo group.

Stapled haemorrhoidopexy: 6 years' experience of a referral centre

AIM

To prospectively evaluate the long-term results and assess patient satisfaction after stapled haemorrhoidopexy (HS).

METHOD

A total of 150 patients (121 male patients) with symptomatic grade II (n = 50) or III (n = 100) haemorrhoids underwent stapled HS. Patients were followed up during consultations at regular intervals, allowing prospective data collection. A final telephone follow up was also undertaken.

RESULTS

Follow up data were obtained for 130 of 150 patients (86.6%). After a median follow up of 39 months (range, 12-72), 90% of the patients were fully satisfied and 92% were free of haemorrhoidal symptoms. There were no intraoperative complications. Postoperative bleeding that required operation was observed in five patients (3.3%). Most late postoperative complications were benign and easily resolved: unexplained pain for over a month (n = 1), external haemorrhoidal thrombosis (n = 2), anal fissure (n = 6) one with hypertrophic papilla, anal fistula (n = 1), rectal stenosis (n = 1), anal incontinence for (n = 1). Eight patients needed rubber band ligation to treat persistent or recurrent symptomatic prolapse. Four patients (2.6%) were reoperated on during the follow up period but none for haemorrhoidal pathology.

CONCLUSION

Stapled HS procedure is effective and has low morbidity, high patient satisfaction and provided good long-term control of haemorrhoidal symptoms in the treatment of second and third-degree haemorrhoids.

Communicating oesophageal duplication cyst with heterotopic pancreatic tissue - an unusual cause of recurrent pneumonia in an infant

Communicating oesophageal duplication cyst with heterotopic pancreatic tissue is rare congenital anomaly and unusual cause of recurrent pneumonia in children. We report a 10-month-old boy who presented with history, examination and investigations suggestive of aspiration pneumonia since birth. The imaging studies revealed a thin walled cavity communicating with the oesophageal lumen that was excised by surgery. Histopathology showed squamous epithelial lining of cyst with heterotopic pancreatic tissue.

CONCLUSION

Communicating oesophageal cyst causing persistent signs and symptoms can be an unusual cause of recurrent pneumonia in an infant that can be diagnosed by further imaging studies.

Quo vadis STARR? A prospective long-term follow-up of stapled transanal rectal resection for obstructed defecation syndrome

INTRODUCTION

Functional and clinical long-term outcome after stapled transanal rectal resection (STARR) in patients with an isolated symptomatic rectocele are investigated. Short-term results after 1 year are comparable with the functional outcome even after 5 years. Eighty per cent of the patients were still satisfied. STARR is an alternative procedure to the conventional surgical approaches for patients with an obstructed defecation syndrome and rectocele. Several studies have reported short-term outcome after STARR, but long-term results are still missing. The objective of this study was to evaluate long-term clinical outcome after STARR with a follow-up of 5 years.

MATERIALS AND METHODS

Twenty patients with only an isolated symptomatic rectocele due to obstructed defecation syndrome were subjected to STARR. Functional and clinical outcome was assessed by Outlet Obstruction Syndrome score (OOS score), Wexner score (WS), and Symptom Severity score (SSS score). Data were prospectively collected over 7 years.

RESULTS

The perioperative morbidity after STARR accounted for 20% (n = 4). One patient was subjected to reoperation due to perforation, two postoperative bleedings occurred, and one patient developed an increasing local granulomatous reaction at the stapler line. The median follow-up accounted for 66 months (range 60-84). Sixteen patients (80%) were satisfied with the functional outcome. The median OOS, SSS and WS score improved significantly already after 1 year in these patients and remained stable at 5-year follow-up. In contrast, four patients were classified as treatment failures since the OOS score and the SSS score showed no improvement. At 5-year follow-up, these patients remained symptomatic without improvement in OOS and SSS scores.

CONCLUSIONS

The STARR procedure is an effective operation in isolated symptomatic rectoceles with regard to relief of the obstructed defecation syndrome. The short-term improvement after STARR predicts long-term outcome in obstructed defecation syndrome caused by a rectocele.

Comparative study of Contour Transtar and STARR procedure for the treatment of obstructed defecation syndrome (ODS)--feasibility, morbidity and early functional results

AIM

Stapled transanal rectal resection (STARR) is a promising new treatment for obstructed defecation syndrome (ODS). It may be performed using either a double-stapling technique (PPH-STARR) or with the new Contour Transtar (CT) device. The aim of this study was to evaluate the two techniques with respect to morbidity and functional outcomes.

METHOD

Patients presenting with ODS were evaluated using standardized clinical and radiological investigations and prospectively entered into a database. A total of 150 Patients were treated with either PPH-STARR (n = 68) or CT (n = 82) and further evaluated at 12 month postoperatively.

RESULTS

The mean size of the resected specimen was 27 cm(2) (SD +/-4.86 cm(2)) in the PPH-STARR group and 46 cm(2) (SD +/-10.6 cm(2)) in the CT group [P < 0.001]. Morbidity was 7.3% (n = 5) in the PPH-STARR group and 7.5% (n = 6) in the CT group. The most common complication was minor postoperative bleeding in both groups (PPH-STARR: n = 2, 2.9%; CT: n = 2, 2.4%) Overall there were no septic complications and no surgical re-interventions. There was a tendency for more postoperative pain following CT (n = 3, 3.6%) as compared with PPH-STARR (n = 1, 1.4%). Constipation Scores (CCS) were 15.50 +/- 5.71 in the PPH-STARR group and 15.70 +/- 5.84 in the CT group preoperatively and decreased significantly to 8.25 (SD +/-1.45) and 8.01 (SD +/-2.31) 12-months after surgery. Values did not differ significantly between the two groups.

CONCLUSIONS

Contour Transtar is as safe and effective as PPH-STARR and provides a true circumferential resection of rectal intussusception. This may benefit selected patients and result in improved long-term durability of the technique.

Evidence-based management of pain after haemorrhoidectomy surgery

BACKGROUND

Haemorrhoidectomy is associated with intense postoperative pain, but optimal evidence-based pain therapy has not been described. The aim of this systematic review was to evaluate the available literature on the management of pain after haemorrhoidal surgery.

METHODS

Randomized studies published in the English language from 1966 to June 2006, assessing analgesic and anaesthetic interventions in adult haemorrhoidal surgery, and reporting pain scores, were retrieved from the Embase and MEDLINE databases.

RESULTS

Of the 207 randomized studies identified, 106 met the inclusion criteria, with mixed methodological quality. Of these, 41 studies evaluating surgical and alternative interventions were excluded. Quantitative analyses were not performed, as there were limited numbers of trials with a sufficiently homogeneous design.

CONCLUSION

Local anaesthetic infiltration, either as a sole technique or as an adjunct to general or regional anaesthesia, and combinations of analgesics (non-steroidal anti-inflammatory drugs, paracetamol and opiates) are recommended. If appropriate, a stapled operation may be preferable.

Tumors of the mediastinum and chest wall

Primary tumors of the mediastinum and chest wall comprise a diverse group of conditions with a wide range of presentations. A thorough knowledge of thoracic anatomy is essential for appropriate diagnosis and treatment. Given their proximity to critical structures, treatment of these tumors is often challenging. Although surgery is the mainstay of therapy for most mediastinal and chest wall tumors, a multidisciplinary approach is valuable in many cases.

Gastrointestinal images: complete tubular duplication of the oesophagus in an adult

INTRODUCTION

Duplication of the oesophagus is a rare congenital abnormality that usually presents in children. Presentation in adults is extremely rare.

CASE HISTORY

We report a case of a19-year-old gentleman presenting with general gastrointestinal symptoms of pain and dysphagia. Diagnosis was made with CT and contrast studies, demonstrating complete tubular duplication of the oesophagus with communications at both ends of the duplication. The patient was managed conservatively.

DISCUSSION

We describe the difficulty in diagnosing these rare congenital abnormalities. We recommend that with a multi-disciplinary approach, conservative management can be considered.

LigaSure hemorrhoidectomy versus stapled hemorrhoidopexy: a prospective, randomized clinical trial

PURPOSE

This study was designed to compare the outcome of LigaSure hemorrhoidectomy and stapled hemorrhoidopexy for prolapsed hemorrhoids.

METHODS

Consecutive patients with grade III or IV hemorrhoids were randomly assigned to undergo either LigaSure hemorrhoidectomy or stapled hemorrhoidopexy. Data on patient demographic and clinical characteristics, operative details, postoperative pain score on a visual analog scale, number of parenteral analgesic injections, duration of hospital stay, and time to return to work were all prospectively collected. Postoperative complications and recurrence of prolapse were also recorded. Patients were regularly followed for a total period of 12 months.

RESULTS

A total of 68 patients completed the study (34 per group). Patient demographic and clinical characteristics were similar in the 2 groups. No significant differences between LigaSure hemorrhoidectomy and stapled hemorrhoidopexy were observed in mean operating time, postoperative pain score, number of parenteral analgesic injections, duration of hospital stay, or time to return to work. The groups were also similar regarding postoperative complications, except that at 4 weeks postoperatively, residual prolapse was observed in 8 patients (23.5%) in the stapled hemorrhoidopexy group vs. 2 patients (5.9%) in the LigaSure group (P = .040). Rate of recurrence of prolapse at 1 year was higher with stapled hemorrhoidopexy (4 patients, 11.8%) than with the LigaSure procedure (1 patient, 2.9%), but the difference was not significant (P = .163).

CONCLUSIONS

LigaSure hemorrhoidectomy and stapled hemorrhoidopexy yield comparable good results, with a short operative time and minimal side effects in the treatment of grade III and IV hemorrhoids, but with a lower rate of residual prolapse for the LigaSure procedure. Both procedures offer low levels of postoperative pain and therefore are excellent therapeutic options for prolapsed grade III and IV hemorrhoids. A larger controlled study is needed to reach solid conclusions regarding risk of postoperative recurrence of hemorrhoidal prolapse.

Laparoscopic mesh rectopexy for complete rectal prolapse in children: a new simplified technique

PURPOSE

Rectal prolapse in children without underlying conditions is usually a self-limiting problem and requires no surgical treatment. For children with persistent rectal prolapse, a variety of surgical procedures have been described with success. Recently, there are many reports addressing the successful use of different laparoscopic approaches for complete rectal prolapse. We present a novel simplified laparoscopic technique for management of those patients. The aim of this study is to evaluate the results that can be achieved by using this technique in management of persistent complete rectal prolapse in children.

METHODS

We reviewed the reports of 680 patients with primary complete and partial rectal prolapse over the period from August 2000 to August 2008. Fifty-two patients with complete primary rectal prolapse refractory to medical treatment for 2 years underwent a novel simplified technique for laparoscopic mesh rectopexy.

RESULTS

Conservative management was successful with no recurrences in 628 patients (92.4%) while 52 (7.6%) patients did not respond to conservative management at a median follow-up period of 2 years. They were 35 males and 17 females. Their ages ranged from 2 to 14 years (mean 6). All patients were subjected to laparoscopic mesh rectopexy successfully without any conversion. The mean duration of surgery was 40 min. No intraoperative complications were reported, but one patient developed postoperative constipation that responded well to conservative treatment. The mean postoperative hospitalization was 2 days. Two cases were lost to follow-up, while the others were available for 36 months. There was no recurrence.

CONCLUSION

Laparoscopy mesh rectopexy is safe, rapid, effective technique. It improved functional outcome without recurrence. It is associated with minimal postoperative pain and short hospital stay with excellent cosmoses.

Randomized controlled trial comparing rubber band ligation with stapled haemorrhoidopexy for Grade II circumferential haemorrhoids: long-term results

OBJECTIVE

An improved understanding of the pathophysiology of haemorrhoids has resulted in the introduction of new surgical techniques including stapled haemorrhoidopexy (SH). This randomized controlled trial compared the long-term effectiveness of SH with rubber band ligation (RBL) in the treatment of grade II circumferential symptomatic haemorrhoids.

METHOD

A consecutive cohort of patients was randomly allocated to either SH or RBL. Data on haemorrhoidal symptoms, Cleveland continence scores, sphincter assessment, SF-36, EQ-5D, HAD score and prior treatment history were assessed at enrollment and reassessed by long-term postal questionnaire. The details were analysed using spss 12.0 from Microsoft Access.

RESULTS

Sixty patients were allocated by computer block randomization. Both groups were balanced for age, sex and symptoms. Recurrence favoured SH [3 vs 11; OR 0.18, 95% CI (0.03 to 0.86), P = 0.028] at 1 year and, at a mean of 40.67 (31-47) months [4 vs 12; OR 0.23, 95% CI (0.05, 0.95); P = 0.039]. SH patients experienced prolonged pain [Median (IQR) = 7 (5,7) vs 3 (1,7), P = 0.008] and took a longer time to return to work [6 (3,7) vs 3 (1,6) days, P = 0.018]. This was no significant difference in quality of life.

CONCLUSION

Stapled haemorrhoidopexy achieved better disease control at 1 year without any major complication. This was sustained in the long-term. Further studies with greater patient numbers are needed to confirm this study.

Systematic review on ventral rectopexy for rectal prolapse and intussusception

OBJECTIVE

This systematic review assesses the effectiveness of ventral rectopexy (VR) surgery for treatment of rectal prolapse (RP) and rectal intussusception (RI) in adults. Method MEDLINE, EMBASE, Scopus and other relevant databases were searched to identify studies. Randomized controlled trials or nonrandomized studies with more than 10 patients receiving ventral mesh rectopexy surgery were considered for the review.

RESULTS

Twelve nonrandomized case series studies with 728 patients in total are included in the review. Seven studies used the Orr-Loygue procedure (VR with posterior rectal mobilization to the pelvic floor) and five studies used VR without posterior rectal mobilization. Overall weighted mean percentage decrease in faecal incontinence (FI) rate was 45%. The weighted mean percentage decrease in constipation rate was 24%. Weighted mean recurrence rate was 3.4%.

CONCLUSIONS

There are limitations in published literature on VR. The available data indicate that VR has low recurrence and improves FI in patients suffering from these conditions. There is a greater reduction in postoperative constipation if VR is used without posterior rectal mobilization.

Residual skin tags following procedure for prolapse and hemorrhoids: differentiation from recurrence

PURPOSE

The aim of this study was to compare the incidence of recurrence and residual skin tag after the procedure for prolapse and hemorrhoids (PPH) versus conventional hemorrhoidectomy (CH) in the Chinese- and English-language literature to explore the definition of recurrence after PPH.

METHODS

Related Chinese- and English-language literature was collected by several methods. Meta-analysis was used to compare the incidence of recurrence and residual skin tag of PPH versus CH.

RESULTS

In China, 13.94% of hemorrhoids had a skin tag after PPH. The mean recurrence rate after PPH was 3.23% (range 0.40-26.44%). Our meta-analysis of PPH versus CH of the Chinese studies showed that PPH had a significantly lower recurrence rate-13 studies, odds ratio (OR) 0.27, 95% confidence interval (CI) 0.17-0.42, p < 0.00001-and a higher incidence of skin tags with no significance-6 studies, OR 3.42, 95% CI 0.49-24.04, p = 0.22. Our meta-analysis of PPH versus CH among the English-language studies showed that PPH had a significantly higher recurrence rate-17 studies, 636 patients in the PPH group vs. 625 patients in the CH group, OR 2.96, 95% CI 1.57-5.56, p = 0.0008-and a significantly higher incidence of residual skin tags-8 studies, 297 patients in the PPH group vs. 289 patients in the CH group, OR 1.88, 95% CI 1.15-3.05, p = 0.01. However, the recurrence of prolapse was stated to be ascertained by anorectal examination in only six studies; meta-analysis of the six studies showed that PPH was not associated with a higher recurrence-six studies, 230 patients in the PPH group vs. 220 patients in the CH group; OR 1.87, 95% CI 0.70-5.00, p = 0.22.

CONCLUSIONS

PPH is not associated with a higher recurrence rate but is associated with a higher incidence of skin tags compared with CH. The reported high recurrence rates are probably caused by improper inclusion of residual skin tags into the recurrence data. Surgeons should perform anorectal examinations to differentiate a residual skin tag from a recurrence.

Intraabdominal bronchogenic cyst

INTRODUCTION

Bronchogenic cyst is pathology of the respiratory track. It consists of a defect during the embryological development of the tracheobronchial tree. Most common presentation is as a solid or cystic mass located in mediastinum, and it is usually diagnosed in relation to respiratory problems or recurrent infections in children. In adulthood, it is a rare pathology, and its diagnosis is usually incidental.

CASE REPORT

We present a case of a patient with a paraesophageal cystic mass suggestive of intraabdominal esophageal duplication cyst but, after the histopathological examination, was discovered to be a bronchogenic cyst, something extremely rare as in most cases of subdiaphragmatic location; bronchogenic cysts appear as retroperitoneal lesions.

DISCUSSION

After we review the current literature, surgical extirpation appears to be the treatment of choice due to potential complications, and laparoscopic approach is a feasibily and safe procedure for this pathology up to date.

Multidetector computed tomography and 3-dimensional imaging: preoperative evaluation of thoracic vascular and tracheobronchial anomalies and abnormalities in pediatric patients

In the past decade, rapid technical developments and advancements of multidetector computed tomography (MDCT) have revolutionized the preoperative imaging evaluation of thoracic vascular and tracheobronchial anomalies and abnormalities in infants and children. Multidetector computed tomography enables noninvasive, rapid, high-resolution, and 3-dimensional (3D) imaging of the thorax in pediatric patients that provides comprehensive preoperative surgical guidance for pediatric surgeons. With the increasing availability of MDCT and 3D imaging, a practical review is needed for the pediatric surgeon of the evolving role of these techniques in the preoperative evaluation of surgical lesions in infants and children. This article focuses on the review of advantages and disadvantages of MDCT in comparison to other imaging modalities, 2D and 3D imaging postprocessing techniques, and MDCT and 3D imaging appearance of various thoracic vascular and tracheobronchial anomalies and abnormalities in pediatric patients. The primary aim of this article was to facilitate the pediatric surgeons' ability to successfully incorporate MDCT and 3D imaging as a routine preoperative imaging tool for the evaluation of thoracic surgical lesions in infants and children.

Laparoscopic management of persistent complete rectal prolapse in children

BACKGROUND

Rectal prolapse is a relatively common condition in children. The multiplicity of surgical approaches used for rectal prolapse indicates that there is no single approach universally accepted and applicable to all cases. The laparoscopic approach promises to become the criterion standard for the management of full-thickness rectal prolapse in children. The aim of this study was to review our experience over the last 5 years and to evaluate the results that can be achieved by using laparoscopy in management of complete rectal prolapse in children.

PATIENTS AND METHODS

Forty patients presented with complete rectal prolapse and fecal incontinence grades (3-4) according to Rintala scale (37 secondary to prolapse and 3 neuropathic) had been operated upon laparoscopically from August 2003 to August 2008. They were subjected to clinical examination, investigations, pre- and postoperative electromyogram activities for external sphincter, puborectalis, and pelvic floor muscles. The pathophysiologic changes for each case was identified and dealt with laparoscopically (laparoscopic suture rectopexy, laparoscopic mesh rectopexy, laparoscopic resection rectopexy, and laparoscopic levatorplasty).

RESULTS

Among the 40 children with complete rectal prolapse, 22 were males and 18 females. Their median age was 9 years (range, 4-14 years). All cases (n = 40) showed a redundant rectosigmoid junction. Additional laxity of the pelvic floor was present in 32, rectoanal intussusception in 27, anterior wall rectoanal intussusception in 3, and rectosacral hernia in 5 cases. All procedures were completed laparoscopically. The median duration of surgery was 60 minutes (range, 50-70 minutes) for suture rectopexy, 90 minutes (range, 60-110 minutes) for mesh rectopexy, 110 minutes (range, 95-160 minutes) for resection rectopexy, and 120 minutes (range, 100-150 minutes) for laparoscopic levatorplasty. No intraoperative complications occurred in this study. Median postoperative hospitalization was 3 days (range, 2-5 days). Electromyogram studies showed statistically significant improvement during rest, minimal volition, and squeezing in all cases except those children with spina bifida and meningomyelocele. The only complications were postoperative constipation and external colonic fistula. Significant improvement of the continence score was achieved in all cases. The average follow-up time was 36 months. There were no recurrences.

CONCLUSION

The use of laparoscopy in the management of complete rectal prolapse is safe, effective, and associated with improved functional outcome. It saved the patients multiple operations and is associated with minimal postoperative pain and short hospital stay.

Randomized clinical trial of symptom control after stapled anopexy or diathermy excision for haemorrhoid prolapse

BACKGROUND

: This multicentre randomized clinical trial studied how symptoms improved after either stapled anopexy or diathermy excision of haemorrhoids.

METHODS

: The study involved 18 hospitals in Sweden, Denmark and the UK. Some 207 patients were randomized to either anopexy or Milligan-Morgan haemorrhoidectomy, of whom 90 in each group were operated on. Patients reported symptoms before surgery and after 1 year. Daily postoperative pain scores were recorded in a patient diary. Surgeons evaluated the anal anatomy before surgery and after 1 year.

RESULTS

: Correction of prolapse in the anopexy and haemorrhoidectomy groups was similar at 1 year (88 and 90 per cent respectively; P = 0.80). Freedom from symptoms was obtained in 44 and 69 per cent respectively (P = 0.002). Stapled anopexy was associated with less postoperative pain, which resolved more quickly (P = 0.004). Significant improvements were noted in anal continence and well-being 1 year after both operations (P < 0.001). Excessive pain was the most common complication after diathermy excision and disturbed bowel function after stapled anopexy.

CONCLUSION

: Haemorrhoidal prolapse was corrected equally by either operation. Diathermy haemorrhoidectomy gave better symptom relief but was more painful. Neither operation provided complete cure but well-being was greatly improved.

[Mediastinal cysts: clinical approach and treatment]

Mediastinal cysts (MC), mainly from embryonic origin, are benign and rare malformative lesions, gathering several varieties according to tissue origin. Diagnosis is mostly obtained thanks to tomodensitometry performance and sometimes by magnetic resonance imaging. It may be more difficult in some atypical topographies and in case of bulky MC. The most frequent, springing from division abnormality from embryonic foregut ("foregut cysts" in English literature), are primarily bronchogenic cysts (50 to 60 % of MC), which are symptomatic in 30 to 80 % of cases. Coelomic cysts, lined by a mesothelium, result from embryologic abnormality by incomplete fusion of mesenchymal coelomic lacunae. Rarely symptomatic, excepted in cases of very large cysts, they are mainly pleuropericardic cysts (PPC) that represent 30 % of MC. Thymic cysts, around 15 % of MC, are most often asymptomatic. Cystic lymphangiomas (CL) are congenital lymphatic malformations more frequent and symptomatic in children. Diagnosed in older patients, they are most often acquired and asymptomatic. The only radical and definitive treatment is complete surgical resection of the cyst. It allows suppression of symptoms, procurement of a formal diagnosis and prevention of complications. This resection, generally indicated for all symptomatic cysts, large-sized even asymptomatic and in case of non formal diagnosis, is now recommended for all kinds of cysts except for asymptomatic PPC. This strategy is justified considering morbidity and mortality rising rates in patients treated by surgical resection at time of local complications of the cyst. Surgery is commonly performed by videothoracoscopy or by video-assisted mini-thoracotomy, mainly for PPC and CL. The more conventional thoracotomy is performed in surgery for cysts, which are adhesive to nearby structures. PPC just need a simple follow-up, and surgery is required only in case of symptoms and increasing size. In total, surgical indications for MC are large and accepted because of null postoperative mortality and very low rate of morbidity thanks to mini-invasive surgery. This militates for early surgery, without waiting for cystic complications leading to peroperative difficulties and increasing risks. This review presents the characteristics of those different cysts and the strategies currently acknowledged for the treatment.

Five serum proteins identified using SELDI-TOF-MS as potential biomarkers of gastric cancer

OBJECTIVE

The aims of this study were to detect serum proteomic patterns in gastric cancer serum samples using Surface-enhanced Laser Desorption/ionization-Time-of-flight-Mass Spectrometry ProteinChip array technology, to screen biomarker candidates, to build diagnostic models and to evaluate their clinical significance.

METHODS

Serum samples from patients with gastric cancer and normal healthy control subjects (n = 125) were analysed using surface-enhanced laser desorption/ionization technology. The spectra were generated on weak cation exchange (WCX2) chips, and protein peak clustering and classification analyses were established using Ciphergen Biomarker Wizard and Biomarker Pattern software, respectively. The diagnostic models were developed and validated by discriminant analysis. In addition, the results of the surface-enhanced laser desorption/ionization model were compared with the biomarkers carcinoembryonic antigen and carbohydrate antigen 199 in a subset of samples using a microparticle enzyme immunoassay.

RESULTS

Five protein peaks at 2046, 3179, 1817, 1725 and 1929 m/z were automatically chosen as components of the best biomarker pattern for diagnosis of gastric cancer. In addition, we identified a single protein peak at 4665 m/z, which could distinguish between stage I/II and stage III/IV gastric cancer with a specificity and sensitivity of 91.6% (11/12) and 95.4% (21/22), respectively. When this biomarker was validated in the second set of samples, the specificity and sensitivity were 91.7% (11/12) and 86.3% (19/22), respectively.

CONCLUSIONS

The present results suggest that serum surface-enhanced laser desorption/ionization protein profiling can distinguish patients with gastric cancer, and in particular stage I/II patients, from normal subjects with a relatively high sensitivity and specificity. Surface-enhanced Laser Desorption/ionization-Time-of-flight-Mass Spectrometry is a potential new diagnostic tool for the screening of gastric cancer.

Paroxysmal atrial fibrillation due to bronchogenic cyst

A 62-year-old man presented newly developed tachyarrhythmia diagnosed as paroxysmal atrial fibrillation (PAF) and was treated with flecainide and enalapril. He underwent a whole-body F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) scan for cancer screening. The FDG-PET images showed a FDG non-avid lesion in the mid mediastinum. He was referred to our hospital for further examination under suspicion of a cardiac tumor in the left atrium. A chest computed tomography scan and magnetic resonance imaging revealed a bronchogenic cyst just under the carina and also compressed left atrium and pulmonary vein from its cranial portion. The cyst was completely excised. After the operation, PAF was stopped and sinus rhythm was preserved. PAF was thought to be due to compression by the bronchogenic cyst.

Solitary splenic metastasis from early gastric cancer: report of a case

Solitary metastasis of a malignancy to the spleen is rare. We herein describe a case of splenic metastasis from early gastric cancer. A 76-year-old man underwent an endoscopic mucosal resection (EMR) for early gastric carcinoma in the cardia. Pathologically, the tumor showed invasion into the submucosal layer, and the stump of the surgical specimen appeared to be positive for malignant cells. He thus underwent a proximal gastrectomy with nodal dissection. One year later, serum carcinoembryonic antigen was elevated, and a splenic mass was detected by computed tomography and ultrasonography. Because the tumor increased in size very gradually and no metastatic lesions were detected at the other sites, we performed a splenectomy. The lesion was pathologically diagnosed as metastasis from the previous gastric carcinoma, and the patient remains healthy to date without recurrence, more than 2 years after the splenectomy. When solitary metastasis to the spleen is suspected during the postoperative follow-up of a patient with gastric cancer, a splenectomy is a potentially effective treatment.

[Paraoesophageal cyst revealed by repeated infections]

Paraoesophagial cyst is an extremely rare congenital malformation of the oesophagus often discovered incidentally in adults. We report the case of a paraoesophageal cyst in a 45 year old man revealed by recurrent chest infections and confirmed by examination at surgery.

New approach to large haemorrhoidal prolapse: double stapled haemorrhoidopexy

PURPOSE

To verify if in large haemorrhoidal prolapse (independently from the degree) in patients with no symptoms of obstructed defaecation syndrome, the use of a stapled hemorrhoidopexy variant, comprising a double stapler haemorrhoidopexy (DSH), makes it possible to reduce the percentage of failures or relapses and to standardise an objective intraoperative parameter for the purpose of quantifying internal prolapses which can then be used as a guide in determining the type of treatment to be provided.

METHODS

Between June 2003 and June 2004, 353 patients were treated for haemorrhoidal prolapse. The patients suffering from large haemorrhoidal prolapse occupying more than half of the length of the anal dilator were intraoperatively selected for DSH.

RESULTS

Eighty-three patients (23.5%) underwent a DSH. The degrees of the large haemorrhoidal prolapse intraoperatively selected for DSH were sub-divided as follows: 7.2% (second), 24% (third) and 68.6% (fourth). The follow-up period was 48 months. There were three cases (3.6%) of residual illnesses and five cases (6%) of a relapse. The following complications were recorded: urgency at <3 months (7.2%), haemostasis revisions (2.4%) and spontaneously draining anterior haematoma (1.2%). The results of the 270 haemorrhoidal prolapse (38 second degree, 159 third degree and 130 fourth degree) treated with the procedure for prolapse and haemorrhoids were: nine (3.3%) residual illness and 12 (4.44%) relapse illness. The following complications were recorded: urgency at <3 months (6.6%), haemostasis revisions (2.5%) and spontaneously draining anterior haematoma (0.7%).

CONCLUSIONS

The intraoperative selection criterion was both efficacious and reproducible. This variant technique, which can be used in large haemorrhoidal prolapses, could allow us to further improve the quality of treatment for haemorrhoidal conditions using stapled haemorrhoidopexy, without increasing the complications.

Video-assisted thoracoscopic excision of intradiaphragmatic bronchogenic cysts: two cases

We report two cases of bronchogenic cyst in the diaphragm. Case 1 was a female patient with hepatocellular carcinoma. Computed tomography showed a tumor in the right lower lung and metastasis was suspected initially because of underlying disease and imaging findings. Case 2 was a female patient who presented with prolonged intermittent cough. Computed tomography showed a tumor in the left lower lung. Both tumors were excised by video-assisted thoracoscopic surgery, and the diagnosis was confirmed by histopathology.

Lymph node staging in esophageal squamous cell carcinoma: a comparative study of endoscopic ultrasonography versus computed tomography

BACKGROUND AND AIM

Endoscopic ultrasonography (EUS) is established as a standard approach for locoregional staging of esophageal cancer. However, only a few published studies have attempted to correlate the station of the abnormal lymph nodes detected by EUS with the definitive histology. We compared EUS and computed tomography (CT) in the initial staging of esophageal squamous cell carcinoma.

METHODS

Consecutive patients with esophageal cancer undergoing EUS were evaluated. EUS findings and patient data including histopatology were collected prospectively and analyzed retrospectively. Lymph node locations were divided into three groups; abdominal (A), paraesophageal (B), and thoracic paratracheal (C).

RESULTS

A total of 365 consecutive patients underwent EUS and 159 patients underwent esophagectomy without neoadjuvant chemotherapy. Thirty-eight patients were excluded (insufficient EUS, etc.), and 121 patients were enrolled. The overall accuracy of EUS was 64% (sensitivity 68%, specificity 58%, positive predictive value [PPV] 68%), CT was 51% (sensitivity 33%, specificity 75%, PPV 64%), and CT + EUS was 64% (sensitivity 74%, specificity 50%, PPV 66%). The accuracy of EUS was higher than CT in Groups A and C. Sensitivity of CT was lower than that of EUS alone and CT + EUS.

CONCLUSIONS

This study has demonstrated that EUS is a more accurate technique than contrast-enhanced CT for detecting abnormal lymph nodes. Sensitivity of CT was lower than that of EUS alone and CT + EUS. But some metastatic lymph nodes in neck and abdominal fields are only detectable by CT. Therefore, both EUS and CT should be undertaken for routine examination prior to treatment of esophageal cancer.

[Warthin tumor with carcinoma: malignant transformation or metastasis?]

We present the unusual case of a cytologically diagnosed Warthin tumor (WT) of long standing with sudden enlargement und subsequent resection. Histologically, the diagnosis of WT was confirmed, but the tumor additionally showed diffuse infiltrates of an adenocarcinoma undergoing unrestrained growth. Warthin tumor with malignant transformation was suspected and radiological staging examinations were conducted. PET scans detected a metastasizing carcinoma of the breast, morphologically identical to the WT infiltrates. Care should always be taken when the diagnosis of malignant WT is made to exclude metastatic disease.

The impact of stapled transanal rectal resection on anorectal function in patients with obstructed defecation syndrome

PURPOSE

A careful preoperative selection of patients was performed in order to identify those eligible for stapled transanal rectal resection to correct obstructed defecation syndrome. The aim was to assess the consequences of surgery on anorectal function and patient outcomes.

METHODS

From January 2004 to June 2007, 33 female patients (median age, 56.3 years; range, 27-77 years) eligible for stapled transanal rectal resection completed standardized questionnaires for the assessment of constipation (constipation scoring system), quality of life (Patient Assessment of Constipation-Quality of Life Questionnaire), and patient satisfaction (visual analogue scale). A complete clinical reassessment including anorectal manometry and defecography was performed after one year.

RESULTS

At a median follow-up of 18 months, significant improvement in constipation scoring system, quality of life, and visual analog scale (P < 0.0001) was observed. Postoperative defecography confirmed the correction of internal rectal prolapse (P < 0.01) and rectocele (P < 0.0001) with an increase in rectal sensitivity (P < 0.0001). Significant correlations were observed between rectocele correction and rectal sensitivity, as evidenced by a decrease in rectal sensory threshold volumes (P = 0.017; Phi = 0.7), increased rectal sensitivity, and patient's satisfaction index (P = 0.011; Phi = 0.64).

CONCLUSIONS

Stapled transanal rectal resection allowed for the correction of rectocele and intussusceptions. These corrections increased rectal sensitivity, diminished symptoms of obstructed defecation syndrome, and improved the quality of life of patients.

Solitary giant splenic metastasis in a patient with metachronous gastric cancers

Splenic metastases from solid tumors are uncommon. They may be observed in a context of multivisceral dissemination or as a solitary lesion. We report the case of an 80-year-old woman with a history of two metachronous gastric cancers treated with distal gastrectomy and resection of the gastric remnant within a period of 15 years, who presented with a huge splenic tumor mass three years after the second operation. Splenectomy was performed. The resection specimens showed a well-circumscribed solid lesion measuring 15 cm in the largest diameter. Histology revealed metastatic gastric cancer. The differential diagnosis and clinical significance of this rare condition is discussed.

Omentoplasty and thoracoplasty for treating postpneumonectomy bronchopleural fistula in a patient previously submitted to aortic prosthesis implantation

Bronchopleural fistula following pneumonectomy is a serious and frightening complication in chest surgery with a high mortality rate. The possibility of curing this complication using a conservative treatment is extremely poor. Below we describe a case of a patient affected by left pleural empyema due to a postpneumonectomy bronchopleural fistula. The patient had previously undergone an aortic prosthesis implantation. He was successfully treated using omental pedicle in order to cover the bronchial stump, to fill the pleural space and to protect the aortic prosthesis. He also underwent thoracoplasty to collapse the residual pleural space. The postoperative course was uneventful. During the follow-up, after thirty months, the patient was asymptomatic, and no recurrence of the fistula was present.
