Laparoscopic intragastric stapled cystogastrostomy for pancreatic pseudocyst

BACKGROUND: Mature symptomatic pancreatic pseudocysts require surgical intervention for their management. In this era of minimal access surgery, several reports are now available of laparoscopic management of pancreatic pseudocysts. PATIENTS AND METHODS: We have performed this procedure in five patients over the past 2 years. Four patients developed the pseudocyst after acute alcoholic pancreatitis and one following acute biliary pancreatitis. The diameter of the pseudocyst ranged from 8 to 12 cm. The procedure was performed using five ports. The Harmonic Scalpel was used to create two ports in the anterior stomach wall through which two balloon trocars were placed into the gastric lumen. Following balloon inflation, the trocars were used to lift up the anterior gastric wall. This created the space for the cystogastrostomy to be fashioned laparoscopically through the balloon trocar. The ball probe of the Harmonic Scalpel was used to puncture the cyst through the posterior gastric wall. The cystogastrostomy was completed by firing an Endo-GIA30 stapler across the fused posterior gastric wall and anterior wall of the cyst. RESULTS: The mean operative time was 90 minutes (range 80-125 minutes). The mean postoperative stay was 3.0 days. One patient had intraoperative bleeding at the anastomotic site, which was easily controlled. CONCLUSION: Laparoscopic cystogastrostomy offers a feasible and safe therapeutic option for selected patients with large symptomatic pancreatic pseudocysts.     

Laparoscopic cystogastrostomy for pancreatic pseudocyst is safe and effective.

Between March 1997 and March 1998, three consecutive patients underwent laparoscopic cystogastrostomy for persistent giant retrogastric pancreatic pseudocyst complicating an attack of acute pancreatitis. The mean cyst diameter was 15 +/- 1 cm (range 14-16). The procedure was performed with four trocars. The anterior wall of the stomach was opened longitudinally. The pseudocyst was entered through the posterior wall of the stomach. A cystogastrostomy was created by suturing the margins of the communication by interrupted nonabsorbable sutures. The mean operative time was 123 +/- 15 min, and there were no postoperative complications. The mean postoperative hospital stay was 4 +/- 1 days. Computed tomography demonstrated complete resolution of the pseudocyst. Laparoscopic cystogastrostomy represents a good therapeutic option for persistent retrogastric pancreatic pseudocyst.     

Robotic-assisted cystogastrostomy for a patient with a pancreatic pseudocyst

Pancreatic pseudocysts are generally treated by endoscopic cystogastrostomy. However, difficult cases involving abscess, necrosis, or risk of hemorrhage often require surgical intervention. Here, we report a case of a robotically assisted cystogastrostomy. The patient presented with an infected pseudocyst with adjacent varices. Use of the da Vinci Surgical System allowed us to create a widely patent anastomosis between the pseudocyst and the stomach. The patient tolerated the procedure well without any complications. This report demonstrates the feasibility of robotic cystogastrostomy.     

Laparoscopic cystogastrostomy for the treatment of pancreatic pseudocysts in children

Pancreatic pseudocysts (PPSs) are common sequelae of pancreatitis and pancreatic trauma. The management is based upon the pseudocyst size and presence of symptoms. Those requiring intervention are often drained using several available options. The use of laparoscopic cystogastrostomy for large and recurrent PPSs has been described in adult patients as a less morbid alternative to open drainage procedures. This technique is considered a novel approach in children.We describe 2 children who had PPSs amenable to laparoscopic cystogastrostomy. The first was an 11-year-old girl who had blunt abdominal trauma from a bicycle handlebar. The second patient was a 7-year-old girl who developed idiopathic pancreatitis. Briefly, 2 ports were placed through the anterior abdominal and gastric walls, and into the lumen of the stomach. This intraluminal placement provided access to the posterior gastric wall. Using electrocautery diathermy, an incision was made through the posterior gastric wall and into the adjacent pseudocyst to obtain complete and unobstructed drainage. Both children tolerated the procedures well with resolution of their PPSs. The patients were each discharged on the fourth postoperative day and have been asymptomatic on 2 years follow-up.Laparoscopic cystogastrostomy is a safe and effective alternative to open cystogastrostomy for the minimally invasive management of PPSs in the pediatric population.     

Massive gastrointestinal hemorrhage following internal drainage of pancreatic pseudocysts]

In operative treatment of pancreatic pseudocysts by inner drainage there is a risk of massive gastrointestinal bleeding particularly following an anastomosis to the stomach. In 10 patients in whom cystogastrostomy or cystoduodenostomy had been performed elsewhere a second laparotomy was necessary because of acute bleeding. In one patient a cystadenoma of the pancreas had been anastomosed to the duodenum by mistake at the previous operation. The leak of obliteration of the cyst is suggested to be the most important factor in the pathophysiology of bleeding. Inner pseudocyst drainage in a disconnected small bowel loop therefore principally should be performed at the lowest point of the cyst. The indication for an inner cyst drainage, however, must be closely examined since simultaneous pathologic changes in the pancreas often justify a resection to remove the origin of the cyst and, further, averting the complications of an inadequate inner pancreatic cyst drainage.

Laparoscopic pancreatic cystogastrostomy

The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.     

Treatment of pancreatic pseudocysts by laparoscopic cystogastrostomy

AIM: To evaluate the clinical results of laparoscopic cystogastrostomy and to determine the potential advantages of this new therapeutic option. PATIENTS AND METHODS: This study concerned 12 patients presenting with pancreatic pseudocyst and operated on by laparoscopic cystogastrostomy between 1997 and 2002. There were five men and seven women with a median age of 46 years (range: 30-72). In ten patients, the pseudocyst developed after acute pancreatitis and the median delay between the acute onset and surgery was 7 months (range: 2-24). In two patients, the pseudocyst was associated with chronic pancreatitis. All the patients had a single cyst bulging into the posterior wall of the stomach and the median cyst diameter was 9 cm (range: 5-14). RESULTS: Endoluminal gastric laparoscopy was used in six patients and intraperitoneal transgastric laparoscopy in six patients. Conversion to open surgery was required in one patient because the cyst could not be correctly localised by laparoscopy. The median size of the cystogastrostomy was 3 cm (range: 2-5). In eight patients, necrotic debris were still present within the cyst. The median operative time was 90 min (range: 60-140) and the median postoperative hospital stay was 6 days (range: 4-24). No mortality was recorded and postoperative morbidity was limited to one haematoma of the rectus sheath on a port site. One patient was readmitted on the 20th postoperative day because of cyst infection due to partial closure of the cystogastrostomy and was treated by endoscopic placement of a stent. One patient was lost for follow-up 2 months after surgery. With a median clinical and radiological follow-up of 12 months (range: 6-36), no recurrence of pancreatic pseudocyst was observed. CONCLUSIONS: In this series, laparoscopic cystogastrostomy is associated with a low postoperative morbidity and an effective permanent result. Laparoscopy has two main advantages: an excellent control of haemostasis and the creation of a wide communication with debridement of the cyst contents thus minimizing the risk of infection or recurrence of the pseudocyst.

Laparoscopic pancreatic cystgastrostomy

Internal drainage of acute pancreatic pseudocysts is indicated 6 weeks after the first documentation of pseudocyst. It is also indicated for symptomatic chronic pseudocysts 6 cm or more in diameter. When pseudocysts are located in close contact with the posterior wall of the stomach, they are best drained by pseudocyst-gastrostomy. This procedure can also be completed making use of intragastric surgical techniques. Under standard laparoscopic observation, three intragastric ports are placed through the abdominal and anterior gastric walls, establishing working channels for a telescope and hand instruments. After the presence of pseudocysts is confirmed, the posterior wall of the stomach and the cyst wall can be incised by electrocautery. After a sufficient drainage orifice is made and the cyst contents are thoroughly debrided, the intragastric ports are removed and defects in the gastric wall are closed with sutures placed via the standard laparoscopic approach. This approach is much less invasive than the conventional approach, which entails a large gastrotomy in the anterior wall of the stomach. This procedure should be the method of choice when interventional radiology or endoscopic intervention fails to effectively drain retrogastric pseudocysts.

Management of pancreatic pseudocyst in the era of laparoscopic surgery – Experience from a tertiary centre

Background In the era of minimally invasive surgery, laparoscopy has a great role to play in the management of pseudocyst of pancreas. We present our surgical experience over the past 12 years (May 1994 to April 2006) in the management of pancreatic pseudocysts. Materials and Methods The total number of cases was 108, with 76 male and 32 female patients. Age ranged from 18 to 70 years. Duration of symptoms ranged from 45 days to 7 months. Fifty-nine patients presented with pain abdomen. Sixty-one patients had co-morbid illness. Ten patients had abdominal mass on clinical examination. Predisposing factors were gallstones in 58 cases, alcohol in 20 cases, trauma in eight cases and post-pancreatectomy in one case. In 21 cases there are no predisposing factors. Results All the cases were successfully operated without any significant intraoperative complication. Laparoscopic cystogastrostomy was done in 90 cases (83.4%), laparoscopic cystojejunostomy in eight cases (7.4%), open cystogastrostomy in two cases (1.8%), and laparoscopic external drainage in eight cases (7.4%). Laparoscopic cholecystectomy was done in 47 cases along with the drainage procedure. The mean operating time was 95 minutes. Mean blood loss was 69 ml. Mean hospital stay was 5.6 days. Percutaneous tube drain to assist decompression of the cyst was kept in all the laparoscopic cystojejunostomy (LCJ) group. Two patients were re-operated for bleeding and gastric outlet obstruction. We had no mortality in the postoperative period. With mean follow up of 54 months (range 3–145 months); only one patient who underwent laparoscopic cystogastrostomy (LCG) earlier in this series had recurrence due to inadequate stoma size. This patient later underwent OCG Conclusion Laparoscopy has a significant role to play in the surgical management of pseudocysts with excellent outcome. It offers all the benefits of minimally invasive surgery to the patients.     

Endoscopic transgastric drainage of pancreatic pseudocyst with the use of Nd:YAG laser

Pancreatic pseudocysts have been successfully managed with endoscopic drainage recently. This report describes a case of endoscopic transgastric drainage using endoscopic ultrasonography (EUS) and an Nd:YAG laser. EUS was used to detect an optimal puncture site of the pseudocyst and to reduce the risk of bleeding and perforation. An Nd:YAG laser was used to minimize the risk of bleeding and to penetrate the thick wall of the pseudocyst. After transgastric cystgastrostomy was performed, an internal stent was placed between the pseudocyst and the stomach. There were no complications associated with endoscopic interventions. Complete resolution of the pseudocyst was observed. Endoscopic transgastric drainage of pancreatic pseudocysts is a recommended approach for selected patients with pancreatic pseudocysts that are uncomplicated and are located adjacent to the stomach. Safe and effective drainage can be achieved without hemorrhage and perforation with the use of EUS, an Nd:YAG laser, and a stent. Furthermore, the Nd:YAG laser facilitated passage through a markedly indurated pseudocyst wall and it seemed to be an effective instrument, especially for pseudocysts with a thick wall.     

Laparoscopic pancreatic cystgastrostomy

Background/Purpose: Internal drainage of acute pancreatic pseudocysts is indicated after the first 6 weeks of pseudocyst documentation. It is also indicated for symptomatic chronic pseudocysts 6 cm or more in diameter. When a pseudocyst is in close contact with the posterior wall of the stomach, it is best drained by pseudocyst gastrostomy. Methods: Intragastric surgical techniques were used in 18 patients with retrogastric pseudocysts. Intragastric ports were successfully placed in all patients, and the presence of pseudocysts was confirmed by needle aspiration in 17. Results: The intragastric approach was successful in 14 patients. In three cases a small abdominal would 8 cm in length was needed. The reasons for such conversion included uncontrollable bleeding from the cystic wall in two cases and a cystic wall in contact with, but not adherent to, the posterior gastric wall in one. Bleeding was controlled through a gastrotomy, and cystgastrostomy was performed. The wound required for conversion was much smaller than that needed for planned open surgery. These procedures are called laparoscopy-assisted cystgastrostomy. Good short- and long-term results were obtained. One patient, in whom the cystgastrostomy was too small, developed a cyst infection and underwent reoperation. Except for this case, no recurrence was observed, and no further treatment was needed. Conclusions: This experience demonstrates that cystgastrostomy with the intragastric surgical technique is a safe, less invasive procedure for effectively draining a retrogastric pseudocyst.

Evaluation of therapeutic options for pancreatic pseudocysts

A review of 81 patients with pancreatic pseudocyst was conducted to assess the value of different treatment modalities. Resection was associated with 18% mortality (two of 11 patients) and 36% morbidity. In three of nine patients undergoing external drainage a recurrent pseudocyst developed, and in one additional patient, a pancreatic fistula persisted. Internal drainage by cystogastrostomy (21 patients) resulted in 9.5% mortality and 9.5% morbidity, whereas cystojejunostomy (33 patients) was associated with a 6% mortality and 6% morbidity. Endoscopic drainage through the posterior wall of the stomach was unsuccessful in the two patients in which it was used. Internal drainage into the stomach, duodenum, or jejunum is a safe and effective approach for most pseudocysts. Persistent symptoms following surgical treatment were primarily related to failure to recognize multiple cysts and/or pancreatic duct obstruction and dilation characteristic or chronic pancreatitis.

Percutaneous cystogastrostomy in patients with pancreatic pseudocysts.

OBJECTIVE: To evaluate the results of percutaneous cystogastrostomy for pancreatic pseudocysts secondary to acute or chronic pancreatitis. DESIGN: Retrospective study with prospective follow-up. SETTING: University hospital, Sweden. PATIENTS: 16 patients with symptomatic pseudocysts (10 men and 6 women, mean age 56 (36-78) years) treated during the period 1993-1999. INTERVENTION: Pseudocystogastrostomy was created under local anaesthesia and fluoroscopic control by percutaneous insertion of a double pigtail catheter. RESULTS: The underlying diagnosis was acute pancreatitis in 10 and chronic pancreatitis in 6 patients. 13 patients had one pseudocyst and 4 had 2 or more with a median diameter of 11 (5-20) cm. The procedure was successful in all but 2 patients, who were operated on. 2 patients experienced pain after the intervention that did not require specific treatment, otherwise no complications were noted. Median hospital stay was 2 days (range 1-60). The median follow-up was 45 (1-94) months. All but 2 patients had successful drainage during follow-up with resolution or regression of the pseudocyst and relief of symptoms (pain and abdominal discomfort). CONCLUSION: Pancreatic pseudocysts were treated by percutaneous cystogastrostomy with good results. Percutaneous cystogastrostomy is a safe, minimally invasive procedure that gives good results at long-term follow-up as well as in the short-term.

A comparison of anterior and posterior approaches for the surgical treatment of pancreatic pseudocyst using laparoscopic cystogastrostomy

BACKGROUND: Laparoscopic treatment of pancreatic pseudocyst allows for definitive drainage with faster recovery. Although many groups have reported their experience with an anterior approach, only a few have done so with a posterior approach. This paper compares the approaches, analyzing their potential benefits and pitfalls. MATERIALS AND METHODS: Seven females and one male underwent laparoscopic cystgastrostomy to treat pancreatic pseudocysts. The anterior approach was performed by opening the stomach anteriorly, localizing the pseudocyst ultrasonographically, draining the cyst with a needle and, via the same opening, using a stapler to form a cystgastrostomy. The posterior approach was performed by directly visualizing the posterior gastric wall and the pseudocyst, opening and draining the cyst with a needle, and using a stapler and running sutures for closure. RESULTS: All patients had gallstone pancreatitis. Cystgastrostomy via the anterior approach was used in 4 patients and via the posterior approach in 4 patients. Dense adhesions required one attempted posterior cystgastrostomy to be converted to an anterior approach. The mean age of the anterior group was 38 years (range, 18-58 years) and hospital stay was 6 days (range, 4-8 days): for the posterior group, mean age was 42 years (range, 40-44 years) and length of stay was 3 days (range, 2-4 days). CONCLUSION: Although both approaches had good results with no complications and short hospital stays, the posterior approach is safer, with a more precise cyst visualization and dissection that permits more tissue to be sent for histopathologic examination. Furthermore, the posterior approach?s larger anastomosis would seem to yield fewer occlusions, which are commonly seen with the anterior approach. The anterior approach is easier to learn, but it requires the opening of the anterior stomach and the use of ultrasound.
