Ruptured spontaneous splenic artery aneurysm: A case report and review of the literature

INTRODUCTION

Splenic artery aneurysm is a rare condition, however, potentially fatal. The importance of splenic artery aneurysm lies in the risk for rupture and life threatening hemorrhage.

PRESENTATION OF CASE

This is a case of a ruptured splenic artery aneurysm in a 58-year-old lady. She presented with hypovolemic shock and intra-peritoneal bleeding. Diagnosis was confirmed by CT angiography and she was managed by operative ligation of the aneurysm with splenectomy and distal pancreatectomy.

DISCUSSION

The literature pointed the presence of some risk factors correlating to the development of splenic artery aneurysm. In this article we discuss a rare case of spontaneous (idiopathic) splenic artery aneurysm and review the literature of this challenging surgical condition.

CONCLUSION

Splenic artery aneurysm needs prompt diagnosis and management to achieve a favorable outcome, high index of suspicion is needed to make the diagnosis in the absence of known risk factors.     

Splenic cyst during pregnancy

INTRODUCTION

Splenic cyst during pregnancy is rare and may result in spontaneous rupture during the third trimester, which increases perinatal morality.

PRESENTATION OF CASE

We present a 27-year-old healthy Caucasian female who presented at 18 weeks gestation with left flank pain, early satiety and weight loss. Imaging studies demonstrated a large complex multiloculated splenic cyst. The patient underwent a successful laparoscopic splenectomy and delivered a healthy child at term without complication.

DISCUSSION

Spontaneous rupture of a splenic cyst during the third trimester incurs a perinatal mortality rate as high as 70%. Surgical management includes open or laparoscopic splenectomy or fenestration and preservation of the spleen.

CONCLUSION

Laparoscopic splenectomy during the second trimester appears to be safe and offers definitive management of a large symptomatic splenic cyst during pregnancy.     

Left-sided portal hypertension: Successful management by laparoscopic splenectomy following splenic artery embolization

INTRODUCTION

Left-sided portal hypertension is a rare clinical condition most often associated with a pancreatic disease. In case of hemorrhage from gastric fundus varices, splenectomy is indicated. Commonly, the operation is carried out by laparotomy, as portal hypertension is considered a relative contraindication to laparoscopic splenectomy (LS). Although some studies have reported the feasibility of the laparoscopic approach in the setting of cirrhosis-related portal hypertension, experience concerning LS in left-sided portal hypertension is lacking.

PRESENTATION OF CASE

A 39-year-old man was admitted to the Emergency Department for haemorrhagic shock due to acute hemorrhage from gastric fundus varices. Diagnostic work up revealed a chronic pancreatitis-related splenic vein thrombosis causing left-sided portal hypertension with gastric fundus varices and splenic cavernoma. Following splenic artery embolization (SAE), the case was successfully managed by LS.

DISCUSSION

The advantages of laparoscopic over open splenectomy include lower complication rate, quicker recovery and shorter hospital stay. Splenic artery embolization prior to LS has been used to reduce intraoperative blood losses and conversion rate, especially in complex cases of splenomegaly or cirrhosis-related portal hypertension. We report a case of complicated left-sided portal hypertension managed by LS following SAE. In spite of the presence of large varices at the splenic hilum, the operation was performed by laparoscopy without any major intraoperative complication, thanks to the reduced venous pressure achieved by SAE.

CONCLUSION

Splenic artery embolization may be a valuable adjunct in case of left-sided portal hypertension requiring splenectomy, allowing a safe dissection of the splenic vessels even by laparoscopy.     

Vacuum Stabilization of the Spleen in Laparoscopic Splenectomy

Background and Objectives:

Recovery from laparoscopic splenectomy is greatly enhanced when compared with recovery from the laparotomy approach, yet a minority of spleens are removed laparoscopically. The spleen is smooth, rounded, and vascular, making it difficult to directly grasp, stabilize, or retract laparoscopically. The LiVac Retractor is a laparoscopic liver retractor comprising a soft silicone open ring that apposes 2 substantially planar surfaces when a vacuum is applied. It was evaluated for its efficacy in stabilization of the spleen during 2 laparoscopic splenectomies.

Methods:

The 2 patients gave consent for laparoscopic splenectomy with splenic retraction using the LiVac Retractor. The entire 3-port laparoscopic procedure was video recorded, with the resected spleens weighed as wet specimens. The patients'' postoperative courses are described.

Results:

The spleen was retracted securely for the duration of the hilar dissection in both patients. Exposure of the splenic hilum was excellent. There were no visible signs of injury to either spleen and recovery of both patients was unremarkable.

Conclusions:

The LiVac Retractor provided stable retraction and excellent exposure of the splenic hilum during both laparoscopic splenectomies, without organ injury. Early hilar dissection with vascular control was facilitated, reducing the risk of bleeding from other components of the dissection.     

Single Incision Laparoscopic Splenectomy in a 5-Year-Old With Hereditary Spherocytosis

Background:

Single incision laparoscopic surgery (SILS) is an emerging technique that has been used as an approach for appendectomy, cholecystectomy, and splenectomy. We describe the technique of single incision laparoscopic splenectomy for hypersplenism in a 5-year-old boy with spherocytosis.

Case Report:

The patient required blood transfusions for anemia secondary to hypersplenism. His spleen measured 9.8 cm in cranio-caudal length on ultrasound. SILS splenectomy was performed through a 2-cm umbilical incision by using 3 ports. The splenic attachments were taken down using an electrosurgical sealing and cutting device, and the hilum was transected with an endosurgical stapler. The spleen was placed in an endosurgical bag, morcellated, and removed from the abdomen via the umbilical incision without complications. Operative time was 84 minutes; blood loss was minimal.

Conclusion:

SILS splenectomy is feasible in pediatric patients. More experience is needed to assess advantages and disadvantages compared with the standard laparoscopic approach.     

Laparoscopic Resection of an Undifferentiated Pleomorphic Splenic Sarcoma

Background:

Splenic tumors are rare. Malignant fibrous histiocytoma (MFH) of the spleen is one of the least common primary splenic tumors. Review of the literature shows that a laparoscopic resection has never been tried.

Method:

We discuss the case of a 76-year-old man with a 7-cm MFH in the spleen and present a review of splenic sarcomas.

Results:

The patient underwent a successful laparoscopic splenectomy; pathology revealed a rare undifferentiated pleomorphic sarcoma of the spleen. A review of the international literature identified 15 additional cases of primary splenic MFH. Survival was rarely longer than 15 months.

Conclusion:

Malignant fibrous histiocytoma of the spleen is an exceedingly rare tumor with a poor prognosis. In experienced hands, laparoscopic splenectomy is a feasible operative choice for primary splenic sarcoma.     

Laparoendoscopic single site (LESS) splenectomy with a conventional laparoscope and instruments

Background and Objectives:

We present 2 cases of laparoendoscopic single site surgery (LESS) splenectomy performed with a conventional laparoscope and instruments, and the use of a novel internal retraction device.

Methods:

One patient underwent LESS splenectomy for idiopathic thrombocytopenia purpura (ITP), and a pediatric patient with sickle cell disease underwent LESS splenectomy and cholecystectomy. In each case, a 2-cm vertical incision was made within the confines of the umbilical ring, and a SILS port (Covidien, Norwalk CT) inserted. A 5-mm, 30-degree laparoscope and standard 5-mm instruments were used. After isolation of the splenic hilum, one 5-mm trocar of the SILS port was upsized to 12mm, and a laparoscopic stapler was used to divide the splenic artery and vein. An internal retractor consisting of a laparoscopic bulldog clamp with a hook attachment was used to retract the gallbladder, and to secure the specimen retrieval bag during splenic extraction, which eliminated the need for a fourth trocar.

Results:

Total operative time was 160 minutes for the LESS splenectomy, and 216 minutes for the LESS splenectomy and cholecystectomy. Both procedures were successfully completed with conventional instrumentation and a SILS port, without the need for additional incisions or trocars. No complications occurred, and both patients had an uneventful recovery.

Conclusions:

LESS splenectomy is a feasible procedure that can be performed safely. Although articulating instruments and laparoscopes may offer advantages, they are not necessary for performing LESS splenectomy.     

Single Access Laparoscopic Splenectomy

Background:

Laparoscopic splenectomy has been performed in a standard fashion with 4 to 5 trocars since the early 1990s. Single access laparoscopy has recently gained interest, but single access laparoscopic splenectomy has not been reported to date. It has the possible benefits of less pain, faster recovery, better cosmesis, with theoretically similar costs to that of traditional trocars.

Methods:

A case is presented and the surgical technique of single access laparoscopic splenectomy is detailed.

Results:

The patient is an otherwise healthy 24-year-old male with medically refractory idiopathic thrombocytopenic purpura and a platelet count of 15 000. A splenectomy was performed using a single incision laparoscopic technique. The patient was placed in a right lateral decubitus position, and a 2.5-cm left upper quadrant incision was made. A multi-instrument flexible single incision port was used that held 3 trocars. A standard splenectomy was performed through this port. A linear stapler was used to transect the splenic hilum. The procedure time was just over 2 hours. The patient did well, was happy with his incision, and was discharged with a platelet count of 108 000.

Conclusions:

Single access laparoscopic splenectomy is feasible in select patients and may provide a less painful, better cosmetic result.     

Robot-Assisted Excision of a Retroperitoneal Mass Between the Left Renal Artery and Vein

Background:

Extra-adrenal pheochromocytomas are rare. Minimally invasive techniques have been utilized for incidentally discovered masses with successful results.

Methods:

We present a case of a 64-year-old female with a 3.5-cm mass located between her left renal artery and vein, treated by a 4-port robot-assisted transperitoneal laparoscopic approach.

Results:

Careful dissection of the tumor away from the renal hilum was accomplished without major vascular injury. A pedicle to the tumor was identified and ligated. The pathology demonstrated a benign pheochromocytoma. To our knowledge, this is the first report of a peri-hilar excision of a pheochromocytoma using this approach.

Conclusion:

Extra-adrenal pheochromocytomas are rare and can present in difficult locations. While surgical excision may be challenging, the da Vinci Robot may be used effectively and safely for the treatment of these perihilar masses.     

Spontaneous Splenic Rupture Four Days after an Open Appendicectomy

Introduction

Spontaneous splenic rupture is a rare but dangerous event that requires prompt diagnosis and frequently an emergency splenectomy. Previous case reports have described the occurrence in patients with medical conditions, anticoagulant treatments, endoscopic procedures, laparoscopic surgery or no particular predisposing factor. Our report is the first to describe the occurrence of spontaneous spleen rupture following a laparotomy conducted in the lower abdomen.

Case History

A 62-year-old woman presented with a 10-day history of right iliac fossa pain radiating to the right leg and associated vomiting. Following a routine blood check and computed tomography (CT), she underwent an open appendicectomy through a lower midline laparotomy for an appendicular abscess. Four days later, she experienced haemorrhagic shock and a second CT scan diagnosed a spontaneous splenic rupture that required a prompt splenectomy.

Conclusions

Our case is the first that describes the spontaneous rupture of the spleen following an open procedure conducted in the lower quadrants. This entity must still be considered as a rare but potential cause for postoperative bleeding when no other obvious sources are identified.     

Splenic torsion requiring splenectomy six years following laparoscopic Nissen fundoplication

Background:

Laparoscopic Nissen fundoplication has become a mainstay in the surgical treatment of gastroesophageal reflux disease, as it has proved to be a durable, well-tolerated procedure. Despite the safety and efficacy associated with this procedure, surgeons performing this advanced laparoscopic surgery should be well versed in the potential intraoperative and postoperative complications.

Methods:

A case is presented of a rare complication of splenic torsion following laparoscopic Nissen fundoplication. Diagnostic evaluations and intraoperative findings are discussed.

Results:

We present an otherwise healthy 41-year-old woman who underwent a laparoscopic Nissen fundoplication 6 years earlier at another medical center and presented with worsening chronic left upper quadrant abdominal pain. She was diagnosed with torsion of the splenic vascular pedicle, resulting in heterogenicity of perfusion with associated hematoma requiring open splenectomy.

Conclusion:

Surgeons should be aware of splenic torsion as a potential, albeit rare, complication related to laparoscopic Nissen fundoplication.     

Percutaneous Ureteral Elevation in Laparoendoscopic Single-Site Radical Nephrectomy

Background and Objectives:

To describe our technique of suture-assisted ureteral retraction during Laparoendoscopic Single-Site (LESS) radical nephrectomy.

Materials and Methods:

A healthy, 39-year-old woman with an incidental 5-cm enhancing left renal mass elected to undergo radical nephrectomy. A 2-cm skin incision was made in the left upper quadrant of the abdomen, and a Covidien SILS port was introduced using standard Hasson techniques. Straight and angled laparoscopic instruments were used to mobilize the kidney outside of Gerota''s fascia. To place the renal vessels on stretch and facilitate hilar dissection, the ureter and lower pole attachments were encircled with a 0-Vicryl suture inserted percutaneously via a disposable fascial closure device. The kidney was bagged and removed intact.

Results:

The procedure was performed without complication with a total operative time of 265 minutes. EBL was minimal at 25mL. The patient was discharged home on postoperative day 1, and final pathology revealed stage pT1b chromophobe renal cell carcinoma with negative surgical margins.

Conclusion:

LESS radical nephrectomy is feasible in select patients. Suture-assisted retraction of the ureter and lower pole attachments using a fascial closure device facilitates safe dissection and control of the renal hilum.     

Laparoscopic Management of Massive Hemobilia From an Intrahepatic Aneurysm

Background:

Intrahepatic arterial aneurysms are rare and typically related to trauma, transplantation, iatrogenic injury, or infection. They account for approximately 10% of clinically significant hemobilia.

Case Report:

We present the case of a 49-year-old man with an intraparenchymal hepatic artery aneurysm that presented as massive hemobilia following a laparoscopic cholecystectomy. The aneurysm could not be managed by interventional embolization and required a left hepatic lobectomy, which was performed laparoscopically.

Discussion:

Evaluation of hemobilia requires a multidisciplinary team approach. The diagnosis of hepatic artery aneurysm can be most readily made by MRI or CT scan. Interventional embolization of the aneurysm may be effective treatment but is not always possible due to anatomic considerations. Where indicated, surgical resection in a manner that preserves a maximal amount of normal hepatic parenchyma is the treatment of choice.

Conclusion:

This is the first report of laparoscopic liver resection performed for bleeding from a hepatic artery aneurysm and adds an effective treatment modality to the surgical armamentarium.     

REDUCE PORT LAPAROSCOPIC SPLENECTOMY FOR GIANT EPITELIAL CYST

Background:

Delaitre and Maignien performed the first successful laparoscopic splenectomy in 1991. After that, laparoscopic splenectomy has become one of the most frequently performed laparoscopic solid organ procedures.

Aim:

To demonstrate the surgical techique of laparoscopic splenetomy with reduced portals.

Methods:

A reduce port laparoscopic splenectomy was performed by using a 10 mm and two 5 mm trocars. To entered the abdomen a trans-umbilical open technique was done and a 10 mm trocar was placed. A subcostal 5 mm trocar was placed under direct vision at the level of the anterior axillary line and another 5 mm port was inserted at the mid-epigastric region. Once it was completely dissected and freed from all of its attachments the hilum, splenic artery and vein, was clipped with hem-o-lock and divided with scissors. Then an endobag was used to retrieve the spleen after being morcellated trough the umbilical incision.

Results:

This technique was used in a 15 years old female with epigastric and left upper quadrant pain. An abdominal ultrasound demonstrated a giant cyst located in the spleen. Laboratory tests findings were normal. The CT scan was also done, and showed a giant cyst, which squeeze the stomach. The patient tolerated well the procedure, with an unremarkable postoperative. She was discharge home 72 h after the surgery.

Conclusion:

The use of reduce port minimizes abdominal trauma and has the hypothetical advantages of shorter postoperative stay, greater pain control, and better cosmesis. Laparoscopic splenectomy for giant cysts by using reduce port trocars is safe and feasible and less invasive.     

Villous Mucinous Cystadenoma of the Appendix in a Postmenopausal Woman

Objective:

To present the case of a postmenopausal woman, who was suspected of having an ovarian cyst. Instead, a cystadenoma of the appendix was discovered during laparoscopy.

Methods:

A 64-year-old postmenopausal nulliparous woman was admitted to our hospital because of a cystic lesion, which had been detected in the course of a routine gynecological examination. The patient underwent vaginal ultrasound, magnetic resonance tomography, and laparoscopy.

Results:

During vaginal ultrasound, a dumbbell-shaped anechogenic cystic structure 70 × 32 × 22 mm in diameter was found in the region of the right adnexa. Magnetic resonance tomography revealed no additional information. During diagnostic laparoscopy, the cystic lesion was found to be a distended appendix. A laparoscopic appendectomy was performed. Subsequent histological analysis revealed a villous mucinous cystadenoma of the appendix with low-grade intraepithelial neoplasia.

Conclusion:

Gynecologists should routinely consider this disease in the differential diagnosis of right lower dumbbell abdominal cysts. Eleven percent to 20% of mucoceles are caused by mucinous cystadenocarcinomas, which carry the risk of peritoneal tumor implantation caused by rupture or laparoscopic resection. Therefore, it should be mandatory that a general surgeon be involved in the laparoscopic procedure and the conversion to laparotomy for resection of the structure.     

Gastric Diverticulum: “A Wayside House of Ill Fame” with a Laparoscopic Solution

Background:

Gastric diverticulum (GD) is an extremely rare disorder that can easily be overlooked when investigating the cause of abdominal pain. Its diagnosis is founded on a history of gastrointestinal symptoms and a typically unrevealing physical examination, and diagnosis requires confirmation from UGI contrast studies, EGD, and CT scan. Symptomatic GD should be kept in consideration as a cause of abdominal issues, because not only is it treatable, but also complications of GD can be life threatening. The surgical treatment of GDs has evolved from thoraco-abdominal incisions in the early twentieth century to the laparoscopic approach used today.

Case Report:

The patient is a 45-y-old male presenting with a 4-mo case of dysphagia, small amounts of regurgitation, and abdominal pain but no other symptoms.

Results:

The patient was diagnosed with a gastric diverticulum, which was subsequently successfully treated with a laparoscopic gastric diverticulectomy.

Conclusion:

Laparoscopic gastric diverticulectomy is a safe procedure and should be considered as an option to treat symptomatic GD.     

Laparoscopic Resection of Giant Adrenal Cavernous Hemangioma

Background:

Large adrenal tumors were initially believed to be a relative contraindication to laparoscopic adrenalectomy.

Methods:

Here we discuss the case of a 42-year-old female with a 12-cm adrenal mass.

Results:

The patient underwent successful laparoscopic resection, and pathology revealed a cavernous hemangioma, a rare benign tumor of the adrenal gland.

Conclusion:

The following is a discussion of the case, laparoscopic resection technique, and brief review of adrenal hemangiomas. In experienced hands, adrenal mass size should not be considered a contraindication to laparoscopic intervention.     

Oversized pseudocysts of the spleen: Report of two cases: Optimal management of oversized pseudocysts of the spleen

INTRODUCTION

Pseudocysts of the spleen are usually asymptomatic and associated with a history of trauma, infection or infarction. In this report, we present two uncommon cases of solitary, oversized pseudocysts of the spleen.

PRESENTATION OF CASE

Two patients (cases A and B), with symptoms of abdominal pain, were investigated. The laboratory and ultrasound examination confirmed the diagnosis of a large, non-parasitic splenic cyst in both cases. Computed tomography described an oversized pseudocyst occupying almost the entire splenic parenchyma in both cases and in patient A, the cyst was located in the splenic hilum. The medical history revealed a previous abdominal injury only in case A. The two patients underwent an open total splenectomy. The pathology examination verified the diagnosis of a non-parasitic splenic pseudocyst.

DISCUSSION

Both patients presented with symptoms, in contrast to the majority of patients with splenic cysts. The medical history of patients with splenic pseudocysts does not always reveal the cause of the pseudocyst formation. Any type of spleen-sparing procedure is not easy to perform in cases of surgical and anatomical difficulty, because of recurrence and the risk of intractable bleeding from the spleen.

CONCLUSION

Partial splenectomy is the recommended method for parenchymal preservation, but total splenectomy is preferred when the splenic cyst is oversized or cannot be excised with safety.     

Laparoscopic Antrectomy for a Proximal Duodenal Brunner Gland Hamartoma

Background:

Adenoma is the most common cause of duodenal polyps, while hamartomas are very rare. We present a patient with a preoperative histology proved diagnosis of isolated duodenal tubulovillous adenomatous polyp with high-grade dysplasia for whom we performed laparoscopic antrectomy.

Case Report:

The patient was a 56-year-old male with vague upper abdominal pain. Investigations revealed a 3-cm x 3-cm mass arising from the duodenal mucosa with no evidence of extraserosal spread. Histopathology documented an adenomatous polyp with high-grade dysplasia, so a laparoscopic antrectomy was performed.

Results:

The patient had an uneventful postoperative period, requiring only 2 doses of parenteral analgesics. He was discharged on the seventh postoperative day. The final histopathological findings were consistent with benign hamartoma. No recurrence has been reported after 14 months of follow-up with endoscopy.

Discussion:

Many procedures have been described for polyps, such as endoscopic excision, duodenectomy, pancreatoduodenectomy, and laparoscopic polyp excision. In our patient, the decision to perform duodenectomy was based on the preoperative findings of a sessile tubulovillous adenomatous polyp with high-grade dysplasia. Histologically, the 2 entities can be identical, especially with the small tissue volume obtained from endoscopic biopsy.

Conclusion:

Given these observations, antrectomy was probably ideal, because endoscopic excision would have been inadequate and even dangerous while pancreatoduodenectomy would have been too radical.
