Hybrid notes: incisionless intragastric stapled cystgastrostomy of a pancreatic pseudocyst

Purpose

We present a case report of a novel hybrid natural orifice transluminal endoscopic surgery (NOTES). The operation performed was a transgastric cystgastrostomy with endoscopic guidance for a pancreatic pseudocyst. This operation was completed entirely through an existing gastrostomy site with no incisions, thus avoiding the peritoneal cavity.

Methods

This is a case of a 7-year-old boy with neurologic impairment from congenital herpes simplex virus encephalitis who is tube fed. He had acute pancreatitis and developed a 9 cm pancreatic pseudocyst. The pseudocyst failed to resolve after 6 weeks and developed a mature wall. Due to a history of multiple abdominal surgeries and known abdominal adhesions, a minimally invasive approach that would avoid entering the peritoneal cavity was the desired approach. The technique involved a trans-oral endoscope for visualization and the use of the gastrostomy as access to the gastric lumen and pseudocyst. The pancreatic pseudocyst was stabilized with two T-fasteners and confirmed with needle aspiration under endoscopic visualization. The pseudocyst was then opened with the LigaSure (Valleylab, Boulder, CO). The cystgastrostomy anastomosis was completed with an Endopath ETS-Flex Articulating Linear Stapler/Cutter (Ethicon Endo-Surgery, Inc, Cincinnati, OH). The operation took less than 2 hours and was completed without an incision. Under the policies of the Human Research Protection Program, review of a single case is outside the scope of the definition of human subjects research and does not require institutional review board review and approval.

Results

The patient did well postoperatively and had a dramatic reduction in size of the pancreatic pseudocyst to 3.5 cm by 2 weeks.

Conclusions

Hybrid NOTES cystgastrostomy performed through an existing gastrocutaneous fistula is an excellent approach for minimally invasive drainage of pancreatic pseudocysts.     

Laparoscopic endogastric pseudocyst gastrostomy: a report of three cases

The transgastric pseudocyst-gastrostomy is the standard approach for internal drainage of persistent and large retrogastric pancreatic pseudocysts that complicate acute necrotizing pancreatitis. We report on the application of a laparoscopic endogastric approach for drainage of pancreatic pseudocysts and discuss the merits of this technique as well as of the other previously described minimally invasive approaches for the management of pancreatic pseudocysts. Between January 2001 and August 2001, three female patients presented with large symptomatic pseudocysts 3-10 months after an episode of acute necrotizing pancreatitis. Internal drainage was effected by a laparoscopic endogastric pseudocyst gastrostomy, and the necrotic pancreas was debrided. There were no conversions and no postoperative complications. The median postoperative hospital stay was 4 days (range, 3-5). All patients remain asymptomatic, and resolution of the pseudocyst was radiologically evident at a median follow-up of 6 months (range, 4-11). The laparoscopic endogastric pseudocyst gastrostomy appears to be a safe and effective minimally invasive approach for internal drainage of large retrogastric pancreatic pseudocysts and facilitates debridement of the necrotic pancreas.     

Minimally invasive open cystgastrostomy for pancreatic pseudocyst

One of the complications of pancreatitis is pancreatic pseudocyst. Many different techniques have been described for internal drainage of pancreatic pseudocyst. Indication for surgery is either symptomatic or large cysts that can turn into complications such as hemorrhage, obstruction, infection, rupture and malignancy. Our technique includes an incision between 5 cm to 9 cm below the left subcostal margin and the opening of the anterior stomach and a posterior cystgastrostomy performed with a reticulated laparoscopic staple. We have been able to perform surgery in a very large pseudocyst (up to 26 cm) in a small amount of time, within 45 min, and with a shorter length of hospital stay (36 h). In this paper, we present our technique on how to approach large pseudocysts utilizing a minimally invasive small incision.     

Therapeutic laparoscopy of the pancreas

OBJECTIVE: To communicate results of laparoscopic treatment of pancreatic pseudocyst (PP) and resection of benign lesions of the pancreas. Perioperative data, surgical outcomes, techniques and insights from 54 cases are presented. SUMMARY BACKGROUND DATA: Although laparoscopic therapy for other solid organs has been widely adopted, reports of therapeutic laparoscopy of the pancreas have been few and of limited numbers, and its role in pancreatic disease is still unclear. METHODS: Eighteen men and 11 women were selected for laparoscopic PP surgery. Four distinct laparoscopic approaches were used. An additional 9 men and 16 women underwent laparoscopic distal pancreatectomy (LDP) using a technique similar to the lesser sac approach. RESULTS: Laparoscopic PP surgery was completed successfully in 28 of 29 patients. The overall mean operative time was 2.8 hours and the mean postoperative length of stay was 4.4 days. Of the techniques described, the authors prefer cyst gastrostomy by the lesser sac approach or the minilaparoscopic cystic gastrostomy. LDP was attempted in 25 patients and completed successfully in 23. One underwent a successful hand-assisted enucleation of an insulinoma. In 12 cases the spleen was preserved. Mean operative time was 3.7 hours, and mean postoperative length of stay was 4.1 days. CONCLUSIONS: In the authors' experience, minimally invasive treatment of PP produces good results and avoids difficulties linked with percutaneous drainage or endoscopic internal procedures. However, combining upper endoscopy with intragastric laparoscopic surgery offers advantages of both. LDP compares well to open procedures and often allows preservation of the spleen.     

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.     

Laparoscopic pancreatic surgery

In the past, in the pancreas, a minimally invasive technique was only used for diagnostic laparoscopy in evaluating periampullary malignancy. Recent advances in operative techniques and instrumentation have empowered surgeons to perform virtually all procedures in the pancreas, including the Whipple procedure. Some of these procedures represent the most sophisticated application of minimally invasive surgery, and their outcomes are reportedly better than those of conventional open approaches. In addition to the evaluation of resectability in periampullary malignancy, palliative procedures, including biliary bypasses and gastrojejunostomy, can be performed laparoscopically. Although it is reportedly feasible to perform a Whipple procedure laparescopically, no benefit of the laparoscopic approach over the conventional open approach has been documented. Laparoscopic distal pancreatectomy, with or without preserving the spleen, is technically easier than the Whipple procedure, and is more widely accepted. Indications for laparoscopic distal pancreatectomy include cystic neoplasms and islet-cell tumors located in the pancreatic body or tail. Complications of acute and chronic pancreatitis may be treated with the use of surgical laparoscopy. When infected necrotizing pancreatitis is identified, surgical intervention for drainage and debridement is required. According to the type and location of infected necrotizing pancreatitis, three laparoscopic operative approaches have been reported: infracolic debridement, retroperitoneal debridement, and laparoscopic transgastric pancreatic necrosectomy. When internal drainage is indicated for a pseudocyst, a minimally invasive technique is a promising option. Laparoscopic pseudocyst gastrostomy, cyst jejunostomy, or cyst duodenostomy can be performed, depending on the size and location of the pseudocyst. Especially when a pseudocyst is located in close contact with the posterior wall of the stomach, it is best drained by a pseudocyst gastrostomy, which can also be done with the use of an intragastric operative technique.     

Primary and overall success rates for clinical outcomes after laparoscopic, endoscopic, and open pancreatic cystgastrostomy for pancreatic pseudocysts

Background  Internal drainage of pancreatic pseudocysts can be accomplished by traditional open or minimally invasive laparoscopic or endoscopic approaches. This study aimed to evaluate the primary and overall success rates and clinical outcomes after laparoscopic, endoscopic, and open pancreatic cystgastrostomy for pancreatic pseudocysts. Methods  Records of 83 patients undergoing laparoscopic (n = 16), endoscopic (n = 45), and open (n = 22) pancreatic cystgastrostomy were analyzed on an intention-to-treat basis. Results  There were no significant differences (p < 0.05) in the mean patient age (years), gender, body mass index (BMI) (kg/m²), etiology of pancreatitis (% gallstone), or size (cm) of pancreatic pseudocyst between the groups. Grade 2 or greater complications occurred within 30 days of the primary procedure for 31.5% of the laparoscopic patients, 15.6% of the endoscopic patients, and 22.7% of the open patients (nonsignificant differences). The follow-up evaluation for 75 patients (90.4%) was performed at a mean interval of 9.5 months (range, 1–40 months). The primary compared with the overall success rate, defined as cyst resolution, was 51.1% vs. 84.6% for the endoscopic group, 87.5% vs. 93.8% for the laparoscopic group, and 81.2% vs. 90.9% for the open group. The primary success rate was significantly higher (p < 0.01) for laparoscopic and open groups than for the endoscopic group, but the overall success rate was equivalent across the groups (nonsignificant differences). Primary endoscopic failures were salvaged by open pancreatic cystgastrostomy (n = 13), percutaneous drainage (n = 3), and repeat endoscopic drainage (n = 6). Conclusions  Laparoscopic and open pancreatic cystgastrostomy both have a higher primary success rate than endoscopic internal drainage, although repeat endoscopic cystgastrostomy provides overall success for selected patients.     

Management of pancreatic pseudocysts

BACKGROUND: This review analyses the outcome for patients with acute and chronic pancreatic pseudocysts managed in two major referral centres. PATIENTS AND METHODS: From 1987 to 1997, 33 patients were treated with either acute (n = 19) or chronic (n = 14) pseudocysts. Procedures performed included cystgastrostomy (64%), cystduodenostomy (6%), cystjejunostomy (3%), distal pancreatectomy with resection of pseudocyst (12%), laparotomy with external drainage (9%), endoscopic transpapillary stenting (3%) and endoscopic pancreatic duct sphincterotomy with percutaneous drainage of the pseudocyst (3%). RESULTS: All patients had resolution of their pseudocyst and no patient developed recurrence. There were no deaths in this series. There was a 9% incidence of major complications and a 21% incidence of minor complications. Outcome was excellent in 63% and good in 27% of patients. Two patients (6%) had persistent chronic pain and one patient (3%) had evidence of exocrine pancreatic insufficiency with malabsorption. CONCLUSIONS: Surgical internal drainage of pancreatic pseudocysts can be performed safely with low morbidity and mortality provided patients are carefully selected and their medical management is optimized. Although minimally invasive techniques now offer a variety of treatment options, open surgical drainage is still indicated for a significant number of cases.     

Laparoscopic cystogastrostomy for pancreatic pseudocyst: a case report.

A 49-year-old man with a history of acute pancreatitis was hospitalized with a diagnosis of pancreatic pseudocyst. Ultrasonography, computed tomography, and magnetic resonance imaging all demonstrated a homogeneous cyst, 9 x 4 cm in size, at the tail of the pancreas without mural nodules or septa. Because an intestinal structure was identified between the cyst and stomach preoperatively by computed tomography and endoscopic ultrasonography, laparoscopic cystogastrostomy was carried out instead of percutaneous or endoscopic cyst drainage. The cyst was exposed by dissecting the lesser omentum and found to have no adhesion to the surrounding tissues. Anastomosis was performed using an endoscopic linear stapler via small cystotomy and gastrotomy openings on the lesser curvature, which were then sutured laparoscopically. The postoperative course was uneventful. Laparoscopic surgery is recommended as a safe, reliable, and minimally invasive treatment for managing pancreatic pseudocyst.     

胰腺假性囊肿治疗方式的选择与评价

目的 对胰腺假性囊肿的治疗方式和效果进行评价。方法 对1990年1月至2002年3月收治的114例胰腺假性囊肿的处理方式、效果及并发症进行回顾性分析。结果 25例未行手术治疗,其中23例在随访期间囊肿自行吸收。CT引导下经皮置管引流组29例,有效率67．85％。外科手术治疗60例,死亡率5％(3／60),手术方式包括：外引流8例,死亡率12．5％(1／8);假性囊肿切除13例;囊肿十二指肠吻合1例;囊肿胃吻合19例,术后消化道出血的发生率为36．8％(7／19),死亡率5．26％(1／19);囊肿空肠Roux-en-Y吻合19例,术后消化道出血的发生率为15．8％(3／19),死亡率5．26％(1／19)。结论 CT引导下经皮置管引流创伤小,操作相对简单,是传统开腹外引流术的有效替代方式。虽然微创技术使胰腺假性囊肿的治疗方式多样化,但仍有不少患者需要外科手术治疗。囊肿胃吻合术后消化道出血的发生率高于囊肿空肠Roux-en-Y吻合术,但多数易于控制,仍然是一种简单合理的内引流术式。对于难以排除恶性的假性囊肿,应尽量手术切除。     

Stapled laparoscopic cystgastrostomy

Background The goal of this study was to assess the clinical outcome of patients undergoing laparoscopic stapled cystgastrostomy for pancreatic pseudocysts in contact with the posterior wall of the stomach.Methods We performed a case note review of all patients who have undergone stapled laparoscopic cystgastrostomy in Norwich, UK. The cystgastrostomy was fashioned through an anterior gastrotomy using a vascular ETS stapling device in all cases.Results Fifteen patients have undergone stapled laparoscopic cystgastrostomy. The procedure was completed successfully in 12 patients. Three procedures were converted to open surgery for technical reasons. There were no complications due to bleeding from the cystgastrostomy. Early complications included systemic sepsis (one), bleeding gastric ulcer (one) and pseudocyst recurrence due to partial closure of the cystgastrostomy (two). No late recurrences or other complications have been found at a median follow-up of 37 months.Conclusion Stapled laparoscopic cystgastrostomy is a safe and effective procedure for draining pancreatic pseudocysts in contact with the posterior wall of the stomach. The use of a hemostatic stapling device to fashion the cystgastrostomy may reduce the risk of catastrophic hemorrhage from the pseudocyst wall.     

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.     

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 Roux-en-Y pancreatic cyst-jejunostomy

Background: The surgical management of pancreatic pseudocysts can be established through a variety of techniques. Internal drainage has consistently proven to be the treatment of choice for both acute and chronic pancreatic pseudocysts. With the growing popularity of minimally invasive surgery and improvements in surgical technique, laparoscopic internal drainage procedures for pancreatic pseudocysts are being attempted. While most authors have focused on laparoscopic cyst-gastrostomies, few have written about laparoscopic cyst-jejunostomies. Methods: In this article, we report our experience with eight laparoscopic Roux-en-Y cyst-jejunostomies. Of the eight patients, six had alcoholic pancreatitis, and two had gallstone pancreatitis. There were five men and three women with a mean age of 48 (range 35–71 years). Results: The mean operative time was 150 min, with a range of 100–215 min. We report a mean EBL of 78 cc, a minor complication rate of 20%, and no major complications or mortalities. Conclusions: These data compare favorably with both open and laparoscopic internal drainage procedures. Laparoscopic cyst-jejunostomy offers a feasible alternative in the minimally invasive management of pancreatic pseudocyst.

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.

Current status of laparoscopic surgery of the pancreas

Laparoscopic surgery of the pancreas remains, other than for certain clear indications, primarily investigational. However, in the past few years, laparoscopic therapy for pancreatic diseases has made significant strides and will undoubtedly contribute increasingly to the care of the surgical patient with pancreatic disease. This review discusses the current status of minimally invasive surgical therapy of pancreatic diseases and reviews the current literature. There are four major areas of clinical and laboratory investigation, including diagnostic laparoscopy for staging of pancreatic cancer, laparoscopic palliation of unresectable pancreatic cancer, laparoscopic management of pancreatic pseudocyst, and laparoscopic partial pancreatectomy (pancreaticoduodenectomy, distal pancreatectomy, and enucleation for islet cell tumors). The increased sensitivity of staging laparoscopy with laparoscopic ultrasound as a staging modality in the diagnosis of previously unrecognized metastatic disease from pancreatic cancer is clearly the most utilitarian application of laparoscopic technology in this patient population. Additionally, a natural extension of staging laparoscopy with laparoscopic ultrasound is the ability to improve the quality of life for the patient with unresectable pancreatic cancer by palliating the biliary and gastrointestinal obstruction and the debilitating pain, without the need for and morbidity of open laparotomy. Laparoscopic internal drainage of pancreatic pseudocysts remains early in its development but appears to have potential benefit from application of minimal access techniques. And laparoscopic partial pancreatectomy, both pancreaticoduodenectomy, and, to a lesser degree, distal pancreatectomy, remain primarily investigational without clearly established benefits from the use of minimal access techniques.

Minimally invasive approaches to the management of pancreatic pseudocysts: review of the literature

Although one third or more of pancreatic pseudocysts might resolve spontaneously, interventional therapy is required for most. Several minimally invasive management approaches are now available, including percutaneous drainage under radiologic control, endoscopic transpapillary or transmural drainage, and laparoscopic internal drainage. This paper reviews the methodology, applications, advantages, shortcomings, and results of these management approaches. A computerized search was made of the MEDLINE, PREMEDLINE, and EMBASE databases using the search words pancreatic and pseudocysts and all relevant articles in English Language or with English abstracts were retrieved. In addition, cross-references from the identified articles were reviewed. Percutaneous drainage is best applied to pseudocysts complicated with secondary infection and in critically ill patients or those unfit for surgery. Radiologic drainage, however, risks the introduction of secondary infection and the formation of an external pancreatic fistula, and is associated with high recurrence rates. Endoscopic transpapillary drainage is beneficial for pseudocysts that communicate with the pancreatic duct and when a dependent drainage could be established. Endoscopic transmural (transgastric or transduodenal) drainage offers good results in the management of suitably located pseudocysts that complicate chronic pancreatitis, but is associated with high rates of failure to drain, secondary infection, and recurrence when pseudocysts that complicate acute necrotizing pancreatitis are approached. Laparoscopic pseudocyst gastrostomy or pseudocyst jejunostomy achieves adequate internal drainage, facilitates concomitant debridement of necrotic tissue within acute pseudocysts, and achieves good results with minimal morbidity. A randomized controlled trial that compares laparoscopic and endoscopic drainage techniques of retrogastric pseudocysts of chronic pancreatitis is required.
