Laparoscopic excision of urachal cyst

Laparoscopic management of urachal cysts

BACKGROUND

The urachus and the urachal remnants represent a failure in the obliteration of the allantois at birth that connects the bladder to the umbilicus. After birth it obliterates and presents as the midline umbilical ligament. Urachal cyst are the most common urachal anomaly in the pediatric population. The traditional surgical approach is a semicircular infraumbilical incision or a lower midline laparotomy.

METHODS

In a 10 years period at Pediatric Surgery Department of Vicenza 16 children were diagnosed with urachal anomalies presenting as abdominal or urinary symptoms. Eight underwent open excision; eight were treated by laparoscopic surgery. The average age was 5.5 years (range, 4 months-13 years) in open group and 10 years (range, 1 month-18 years) in laparoscopic group.

RESULTS

Mean operative time was 63 minutes (range, 35-105 minutes) in open group, 50 minutes (range, 35-90 minutes) in laparoscopic group. There were no postoperative complications. The patients of laparoscopic group were all discharged after few days (range, 2-4 days). Pathological examination confirmed a benign urachal remnant in all cases. Reporting our experience since comparing the two surgical approaches we want to describe the technique step by step of laparoscopic urachal cyst excision as minimally invasive diagnostic and surgical techniques.

CONCLUSIONS

Laparoscopy represents a useful alternative for the management of persistent or infected urachus, in particular when there's the suspect despite the lack of radiological evidence. The morbidity associated with this approach is very low as the risk or recurrence. Laparoscopy in the management of urachal cyst is safe effective and ensures good cosmesis with all the advantages of minimally invasive approach.

[Study of laparoendoscopic single-site surgery (LESS) for urachal remnants in our department]

OBJECTIVE

We examined laparoendoscopic single-site surgery (LESS) for urachal remnants and evaluated its usefulness and efficacy.

PATIENTS AND METHODS

From August 2011 to July 2012, we underwent this surgery for 5 patients (3 males, 2 females). The mean age was 30.8 (25-36) years old. A 2 cm incision was made around the umbilicus and Access Platform was placed. The entire urachal tissues were excised, and this 2 cm incison was reshaped as the umbilicus.

RESULTS

The median operative time was 220 (156-460) minutes, and the median operative blood loss was 10 (10-70) ml. They had no operative complications, and were discharged 6 (5-14) days after surgery.

CONCLUSIONS

Our surgical procedures have very excellent cosmesis and advantages in particular for young because we reshape as the umbilicus the surgical wound. We think that this surgery can be performed safe and effectively for surgeons trained in the conventional laparoscopic procedures.

Laparoscopic management of complicated urachal remnants

Managing persistent and symptomatic urachal anomalies requires wide surgical excision of all anomalous tissue with a cuff of bladder tissue via the open approach. We report 7 cases with complete laparoscopic removal of symptomatic urachal remnants with or without a cuff of bladder tissue. We expected that this technique would be less invasive and have lower morbidity. We report on the feasibility of this approach, including efficacy and outcomes. Eight patients with a mean age of 36.5 years who had symptomatic urachal diseases underwent laparoscopic excision between July 2004 and July 2012. With the use of four ports, the urachal remnant was dissected transperitoneally and then removed via the umbilicus port. The clinical results of laparoscopic urachal remnant excision as a minimally invasive surgery, the perioperative records, and pathologic results were evaluated. There were no intraoperative or postoperative complications. Mean surgery time was 2.7 hours. Mean hospital stay was 14.6 days. The patients with bladder cuff resection had a long admission and Foley catheterization period (mean, 14.4 and 11 days). Pathological evaluations were 6 cases of infected urachal cysts, 1 case of infected urachal sinus, and 1 case of urachal adenocarcinoma. We found no postoperative complications including any symptom recurrence or voiding difficulty during a mean follow-up of 46.3 months. The perioperative surgical outcomes achieved infection control and symptomatic relief and additionally good cosmesis. Complete laparoscopic removal of symptomatic urachal remnants with or without a cuff of bladder tissue seems to be a safe, effective, and better cosmetic alternative with the advantages of a minimally invasive approach.

Laparoendoscopic single-site surgery for urachal remnants

INTRODUCTION

Urachal remnants are relatively rare but may potentially cause various symptoms and an increased risk for developing adenocarcinoma. Open or laparoscopic surgery is usually used for their resection. Laparoendoscopic single-site surgery has been recently applied in several surgical procedures. This report describes two cases of vesicourachal diverticulum treated by resection using laparoendoscopic single-site surgery.

MATERIALS AND SURGICAL TECHNIQUE

In each case, laparoendoscopic single-site surgery was performed transperitoneally via one port at a subumbilical semicircular incision. Except for a flexible camera and SILS Port, traditional, non-flexible laparoscopic instruments were used. After the induction of general anesthesia, the patient was placed in a supine position (or lithotomy position). A 2.0-cm incision was made semicircumferentially following the natural subumbilical folds. After the umbilical ligament was cut under direct vision, a SILS Port was placed at the incision. The urachus was liberated distally down to the roof of the urinary bladder using 0° 5-mm flexible camera. Vesicourachal diverticulum with a bladder cuff was completely excised under the supporting view of cystoscopy. Both patients' perioperative days were uneventful.

DISCUSSION

Our findings suggest that the laparoendoscopic single-site surgery procedure is safe, minimally invasive and cosmetically acceptable. Therefore, this procedure is an excellent option for the radical resection of urachal remnants.

Robot-assisted laparoscopic management of urachal cysts in adults

We report two cases where a urachal cyst was managed by robot-assisted laparoscopic surgery. A 47-year-old man and a 43-year-old woman presented with gross hematuria and lower abdominal pain, respectively. Diagnosis of urachal cyst was established by computed tomography imaging. Robot-assisted laparoscopic surgery was performed transperitoneally via four ports. Both patients were diagnosed as having a urachal cyst with inflammation. Our experience suggests that robot-assisted laparoscopic excisions of urachal cysts can be performed easily and safely in adults.

Laparoscopic management of urachal cyst associated with umbilical hernia

The urachal cyst is a rare clinical entity of a urachal remnant. It is usually asymptomatic but can present with haematuria, tumour, urachal stone and infection. We present a case of a 63-year-old lady with a body mass index (BMI) of 49 who presented with a painful swelling in the umbilical region associated with an umbilical hernia. An ultrasound and computed tomography (CT) scan showed a suspected herniation of an umbilical remnant cyst through a paraumbilical defect. Laparoscopy confirmed the urachal cyst of 3 cm in size with a band connected with the cyst down to the urinary bladder associated with a 3-cm paraumbilical hernia. We removed the cyst and repaired the hernia laparoscopically uneventfully, after which her recovery was perfect. Radiological and laparoscopic pictures have not been reported in the English literature before. Although this condition is very rare, we suggest that it should be considered in the differential diagnosis of painful paraumbilical swelling. CT scanning and laparoscopy seems to be valuable, especially in obese patients.

Laparoscopic excision of urachal cyst in pediatric age: report of three cases and review of the literature

OBJECTIVE

To determine the role of laparoscopic surgery in the treatment of pediatric urachal disorders.

METHODS

Case reports and a literature review of laparoscopic excision of urachal remnants.

RESULTS

In a five-year period, three children were diagnosed with urachal anomalies presenting as abdominal or urinary symptoms, and were treated by laparoscopic surgery. The average age was 8.3 years (range, 4-13),and there were two girls and one boy. Mean operative time was 90 minutes (range, 60-120), and there were nopostoperative complications. The three patients were all discharged by postoperative day four.

CONCLUSION

Laparoscopy is an effective and safe minimally invasive technique in the management of pediatricurachal anomalies. It is effective even in cases of infected urachal cysts.

A Naval Surgeon's Approach to the Draining Umbilicus

Spontaneous umbilical drainage is an uncommon problem in the adult, for which various congenital or acquired conditions may be responsible. In this paper, we present 3 cases demonstrating an approach that avoids the need for expensive diagnostic imaging. A careful office exam and basic laparoscopic skills are all that is needed. A brief discussion and review of the literature follows.

Laparoscopic partial cystectomy for various bladder pathologies

OBJECTIVE

To present our initial experience with laparoscopic partial cystectomy (LPC) in selected patients with various bladder pathologies.

PATIENTS AND METHODS

Between December 2004 and April 2006, four patients had LPC at our centre (mean age 52 years, range 35-70); the transperitoneal approach was used for three and a pre-peritoneal approach for one. The surgical procedures used sequentially included transurethral incision around the lesion, laparoscopic excision of the lesion (partial cystectomy) and intracorporeal suturing. Laparoscopic pelvic lymphadenectomy was also used for the two patients with malignancy.

RESULTS

All operations proceeded smoothly; the bladder pathologies included one bladder endometriosis, one bladder leiomyoma, one urothelial carcinoma within the bladder diverticulum and one urachal adenocarcinoma. The mean (range) operative duration was 197.5 (120-300) min, the estimated blood loss 70 (50-100) mL, the hospital stay 6.75 (5-9) days, and duration of Foley catheterization 7.25 (6-9) days. No open conversion was required and no patient had peri-operative complications. The surgical margins were free of cancer and the dissected lymph nodes were negative in those two patients with bladder malignancy.

CONCLUSIONS

LPC is safe and feasible in selected patients with various bladder pathologies.

Laparoscopic management for urachal cyst in a 9-year-old boy

We report a boy with urachal cyst managed laparoscopically. A 9-year-old boy was referred from another hospital with a history of low abdominal pain. We laparoscopically excised the urachal cyst, removing all structures within the umbilicovesical fascia, including the urachus and each medial umbilical ligament, as well as the associated peritoneum from the umbilicus to the bladder dome. Laparoscopic management of urachal disease can be performed safely, with minimal postoperative pain, excellent cosmetic results and early ambulation. We advocate the use of laparoscopic treatment of urachal anomalies in children.

Laparoscopic management of urachal remnants in adulthood

BACKGROUND

The aim of this study was to investigate the outcome of laparoscopic excision of urachal remnants (LUR), and to compare the outcome with that of the traditional open excision of urachal remnants (OUR).

METHODS

Between February 2001 and December 2005, six patients with a mean age of 23.8 years who had a symptomatic urachal sinus underwent radical LUR. Using 12 mm and 5 mm ports, the caudal stump of the urachus was ligated with an absorbable clip and divided. The peritoneal and preperitoneal tissue between the medial umbilical ligaments was dissected free of the transversalis fascia. Dissection was carried out along the preperitoneal plane toward the umbilicus. The cephalic side of the lesion was ligated at the umbilicus with an endo-loop and divided. In addition, four patients who underwent a traditional OUR were included. Peri- and postoperative records were reviewed to assess morbidity, recovery, and outcome.

RESULTS

The operative duration was not significantly shorter for the LUR group than the OUR group, but there was generally a reduction in blood loss (mean 16.5 vs 68.3 mL), an earlier resumption of eating (mean 1.3 vs 2.5 days), and a shorter hospital stay (mean 5.3 vs 10.5 days). There were no intraoperative complications in either the LUR or the OUR group. Mean follow up was 5 (range 4-12) months. There were no postoperative complications.

CONCLUSIONS

The results suggest that LUR can be safely and satisfactorily performed in adulthood.

The use of robotically assisted surgery for treating urachal anomalies

OBJECTIVE

To report the management of urachal anomalies using a robotically assisted approach.

PATIENTS AND METHODS

Between January 2005 and February 2006, five patients (mean age 51 years, range 24-68) were diagnosed with urachal anomalies. Two basic robot-assisted surgical approaches were used for excising the urachal anomalies: excision of the urachal remnant via partial cystectomy, and radical cystectomy for excision of urachal adenocarcinoma.

RESULTS

All five cases were successful and the excised specimens were assessed histologically. The short-term oncological outcome in the three patients with histologically confirmed moderately differentiated adenocarcinoma showed no evidence of recurrent disease within a median interval of 8 months. Surveillance follow-up cystoscopy in the patients who had a partial cystectomy showed a well-healed bladder mucosa with no evidence of recurrence.

CONCLUSIONS

Radical excision of the urachal tract with partial cystectomy or radical cystectomy using the da Vinci robot is safe, effective and technically feasible.

Laparoscopic management of complicated urachal remnant in a child

A few cases of laparoscopic surgery for urachal remnant in children has been reported in English literature. With recent developments in minimal invasive surgery, laparoscopic approach for urachal remnant in adulthood is recommended by some laparoscopic surgeons because of its technical feasibility and safety as well as cosmesis. Recently we experienced a case of complicated urachal remnant in a 14-month-old girl, who was managed by laparoscopic approach. At presentation, she complained of high fever and lower urinary tract symptoms. After 6 weeks of antibiotics therapy, laparoscopic surgery was performed transperitoneally via 3 ports. Our experience suggests that laparoscopic excision of urachal remnant can be performed easily and safely in children.

Laparoscopic en bloc partial cystectomy with bilateral pelvic lymphadenectomy for urachal adenocarcinoma

INTRODUCTION

Surgical options for treating urachal adenocarcinoma include radical cystectomy and en bloc partial cystectomy with excision of the urachus and umbilectomy. Recently, laparoscopy has been increasingly used to treat bladder and urachal pathologic findings efficaciously. We describe two techniques for performing laparoscopic en bloc partial cystectomy with bilateral extended pelvic lymphadenectomy.

TECHNICAL CONSIDERATIONS

We performed the procedure in 3 patients with established urachal adenocarcinoma. The anatomic boundaries of resection were similar to those described for open surgery. We used an inverted V-shaped, five-port configuration, with the camera port placed 3 cm supraumbilically. An antegrade approach was performed for tumors less than 5 cm in 2 cases. The steps of the procedure included an inverted V-shaped incision along the peritoneum lateral to the medial umbilical ligament on either side; urachal disconnection, dissection of the urachus using the "twist and roll technique"; anterior cystotomy, circumferential resection of the tumor-bearing bladder dome, under vision; tumor placement in a "lap-bag"; bladder reconstruction using intracorporeal suturing; bilateral extended pelvic lymphadenectomy; placement of catheter and drain; and specimen retrieval. We evolved a retrograde technique for larger size tumors (larger than 5 cm). The procedure was successfully completed in all patients, with a mean operative time of 180 minutes (range 150 to 210). No significant intraoperative or postoperative complications occurred, except for a left inferior epigastric artery injury in 1 case. The resected nodes (range 8 to 11) were free of tumor. No local or distant recurrences were observed at a mean follow-up of 6.5 months (range 4.5 to 9).

CONCLUSIONS

Laparoscopic en bloc partial cystectomy and bilateral extended pelvic lymphadenectomy is a safe, feasible, minimally invasive alternative to open partial cystectomy for urachal tumors.

Laparoscopic partial cystectomy for treatment of adenocarcinoma of the urachus

The treatment of choice for urachal carcinoma has traditionally been an open approach, either by radical cystectomy or the more recently adopted bladder-sparing approach of extended partial cystectomy and umbilectomy. We report for the first time a laparoscopic technique for an extended partial cystectomy with en bloc umbilectomy for the management of urachal carcinoma in a 41-year-old man.

[Dermoid cyst of the urachus: a case report and review of the literature]

The urachus, a normal embryonic remnant of the primitive bladder dome, exists as a fibrous cord in adult. Urachal disorders are not exceptional, and are expression of incomplete regression. Diagnosis is generally ultrasonographic, rarely clinical. We report a case of urachal dermoid cyst revealed by abdominal pain and underline the diagnostic difficulties related to this unusual localization.

Laparoscopic management of complicated urachal remnants

OBJECTIVE

To report our experience with a laparoscopic approach to managing symptomatic urachal anomalies.

PATIENTS AND METHODS

Five patients (median age 19 years, range 2-43) had a laparoscopic excision of a complicated urachal remnant between 2001 and 2004. Three ports were routinely used, although their positioning varied as our technique developed with experience. The urachal remnant was dissected from the umbilicus to the bladder dome and then removed intact.

RESULTS

All five operations had no serious immediate complications and minimal blood loss. One patient developed a small peri-umbilical haematoma after surgery and another had a persistent umbilical discharge at follow-up, and required open excision of residual remnant tissue.

CONCLUSIONS

The laparoscopic approach appears to be a safe and effective alternative to open surgery for this condition. Despite the slight risk of incomplete excision, the reduced morbidity of this procedure and better cosmetic result would appear advantageous.

Retención aguda de orina, “RAO“, como presentación de quiste de uraco

About 2% of adults have an urachal cyst. The diagnosis is usually made due to its clinical complications. We report an inusual case of acute urinary retention due to an urachal cyst, with hipogastric pain and anuria as initial syntoms.

Acute presentation of infected urachal cysts: case report and review of diagnosis and therapeutic interventions

Urachal remnants, although relatively rare, masquerade as a large number of diverse disorders leading to a high rate of misdiagnosis. A typical case is reported in which a 10-year-old boy presented to the Emergency Department twice before being incorrectly diagnosed with a pelvic or lower abdominal periappendiceal abscess. Definitive diagnosis and treatment of an infected urachal cyst were made intraoperatively. A review and discussion of urachal remnants is presented, and a diagnostic algorithm and treatment plan is offered for this entity.

Laparoscopic radical excision of urachal sinus

Persistent urachus is a rare congenital anomaly. Various types of remnants have been described including cyst, alternating sinus, patent urachus, diverticulum, and sinus. The most common presenting symptom of urachal sinus is umbilical discharge. Radical excision of the remnant, with or without a bladder cuff, is essential to prevent future malignant degeneration or recurrence of the remnant. Although open surgical excision has been the treatment of choice for many years, the laparoscopic approach has become an attractive alternative because of its association with less postoperative pain, better cosmesis, and rapid convalescence. Laparoscopic radical excision of a urachal sinus was performed in a 16-year-old female patient who presented with umbilical discharge.

Surgical implications of urachal remnants: Presentation and management

BACKGROUND/PURPOSE

The abdominal manifestations of urachal remnants often prompt referral to the pediatric general surgeon. The purpose of this study was to evaluate the authors' management of this anomaly.

METHODS

The authors performed a retrospective review of patients presenting to their institution with urachal remnants between 1984 and 2001. Clinical and radiographic details of presentation, management, and outcomes are described.

RESULTS

Twenty-six patients presented at a median age of 4 years (range, 2 days to 12 years), 16 were boys, and 18 required inpatient care. Eleven (42%) presented with infection, 7 (27%) with clear drainage, 3 (12%) with umbilical polyps/granulation, 3 (12%) with pain, one (4%) with recurrent urinary tract infections, and one (4%) with an asymptomatic punctum. One had an associated anomaly (hypospadias). Urinalysis and urine cultures did not correlate with infection. Ultrasound scan was diagnostic in greater than 90% of cases. Overall, 20 patients underwent primary cyst excision, and 6 underwent incision and drainage (I&D) with delayed excision. Five patients underwent primary excision while infected, and 2 had postoperative complications (wound infection and urine leak). All 6 patients who underwent 2-stage procedure initially presented with infection, and none had complications.

CONCLUSIONS

Persistent urachal remnants can present at any age with a variety of clinical manifestations. Ultrasound scan is a reliable diagnostic tool. Additional diagnostic studies generally are not warranted. Simple excision of noninfected lesions is appropriate. In cases of acute infection, initial I&D with delayed cyst excision may be preferable to avoid unnecessary complications.

Excision of a urachal sinus with use of a voice-controlled laparoscope

A 34-year-old man with an umbilical urachal sinus underwent a voice-controlled robot-assisted laparoscopic excision. In the operational procedure, three trocars were inserted into the peritoneal cavity. Exploration with a laparoscope revealed a cystic lesion at the middle part of the lower abdomen that extended about 4 cm in the major axis just from the umbilicus. The caudal stump of the urachus was ligated with an absorbable clip and divided. The cephalic side of the lesion was ligated just at the umbilicus with an Endo-Loop and divided. The lesion was then peeled from the peritoneum and taken from the peritoneal cavity. The robot allowed a safer and more secure movement of the scope. The postoperative course was uneventful, the surgical wound scars were very small, and the cosmetic results were satisfactory. There was no recurrence and no transformation of the navel. Our experience was encouraging enough to suggest that voice-controlled robot-assisted laparoscopic excision in patients with urachal disease is a beneficial therapeutic option that is easy, safe, and minimally invasive, with excellent cosmetic results.

Laparoscopic management of complicated urachal disease in children

PURPOSE

The laparoscopic approach to the complete excision of urachal abnormalities in adults has recently been advocated by some groups but little has been reported in the pediatric literature. We highlight the need for the complete removal of symptomatic urachal remnants as well as the feasibility of the laparoscopic approach in children.

MATERIALS AND METHODS

Four children 5 months, 4, 8 and 10 years old, respectively, who presented with complicated urachal disease underwent laparoscopic resection of urachal remnants. We describe the manner of presentation and surgical technique in these 4 cases.

RESULTS

Laparoscopic radical excision was successfully performed in all 4 cases with an uneventful convalescence.

CONCLUSIONS

Our experience suggests that laparoscopic excision of urachal remnants can be safely and satisfactorily performed in children of all ages.

Laparoscopic-assisted removal of a large urachal cyst

A 48-year-old woman was seen because of an abdominal tumor. Laparoscopy was performed for diagnosis and treatment. A large cystic mass was hanging from the anterior abdominal wall and was removed with laparoscopic assistance. Histologic examination revealed a urachal cyst. (J Am Assoc Gynecol Laparosc 8(1):159-160, 2001)

The infected urachal cyst: primary excision versus a staged approach

PURPOSE

We compared outcomes following single or 2-stage repair of infected urachal cysts in the pediatric population.

MATERIALS AND METHODS

We reviewed the records of 17 patients 1 day to 14 years old (median age 22 months) with a urachal cyst. Immediate cyst excision was performed in 6 patients without infection, while those with an abscess underwent single or 2-stage repair.

RESULTS

Median postoperative hospital stay for the urachal abscess group was 14 and 11.5 days for single and 2-stage procedures, respectively. After immediate excision postoperative complications developed in each case, although none occurred with a 2-stage approach.

CONCLUSIONS

In the absence of infection, urachal cyst excision affords the most benign postoperative course. However, when infection is present, perioperative drainage with subsequent total excision, including a cuff of bladder, may offer the most effective surgical option.

Laparoscopic removal of urachal sinus

Disorders of urachal origin are rarely encountered in adults. Traditional treatment consists of a classic laparotomy and total excision of the urachal structure. We report a case of laparoscopic urachal sinus removal that was performed synchronously with laparoscopic cholecystectomy and ovarian cyst excision. We confirm that the laparoscopic technique can be effectively applied for the diagnosis and treatment of urachal anomalies.

Laparoscopic excision of a urachal cyst

OBJECTIVES

To determine the role of laparoscopic surgery in the treatment of urachal disorders.

METHODS

A case report and literature review of laparoscopic urachal cyst procedures.

RESULTS

A 21-year-old man presented with a draining sinus at the umbilicus. A diagnosis of a urachal sinus was made. The patient underwent a laparoscopic excision of the sinus and cyst.

CONCLUSIONS

Minimally invasive techniques such as laparoscopic surgery are the preferred means of managing urologic diseases such as the urachal cyst.
