胰腺假性囊肿的外科治疗：附89例报告

目的：探讨胰腺假性囊肿的治疗策略。方法：回顾性分析近5年湘雅医院普通外科收治的89例胰腺假性囊肿临床资料，根据囊肿部位、形成时间及囊壁厚度，采用非手术治疗20例，经皮囊肿穿刺引流7例，开腹手术62例（外引流8例、内引流45例、囊肿切除9例）。结果： 全组无死亡病例，手术后并发症发生率15.9%，随访3个月至5年，复发率5.6%。结论：胰腺假性囊肿的治疗宜根据情况采用不同方式，非手术治疗适于无并发症者;急诊手术应选择外引流;囊壁成熟者，选择内引流术疗效好。     

胰腺假性囊肿的治疗研究

目的评价胰腺假性囊肿不同治疗方式的效果。方法对1990年1月至2003年4月收治的128例胰腺假性囊肿不同处理方式的效果及并发症进行回顾性分析。结果128例患者中30例未行手术治疗,其中3例失访,27例在随访期间囊肿自行吸收。B超引导下经皮置管引流组22例,有效率60%。外科手术治疗76例,死亡率5.3%(4/76),手术方式包括:外引流10例,死亡率20%(2/10);囊肿胃吻合术14例,术后消化道出血的发生率为42.9%(6/14),死亡率7.1%(1/14);囊肿空肠Roux-en-Y吻合术28例,术后消化道出血的发生率10.7%(3/28),死亡率0%;囊肿十二指肠吻合术3例,死亡率33.3%(1/3);假性囊肿切除术21例。结论B超引导下经皮置管引流创伤小,操作相对简单,但尚未能完全取代传统手术。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。对于怀疑为真性囊肿或囊腺癌者,应尽量手术切除。     

非胰腺手术后胰腺假性囊肿的治疗

目的探讨非胰腺手术后胰腺假性囊肿的治疗方法。方法对近11年来治疗的28例非胰腺手术后胰腺假性囊肿进行回顾性临床分析。结果保守治疗4例。B超引导下经皮多次穿刺10例(其中穿刺后置管外引流3例)。手术行外引流6例,内引流8例。1例外引流无效后,改行内引流。28例均痊愈出院。结论手术后胰腺假性囊肿应采用个体化的治疗原则,早期应采取保守治疗、穿刺抽液或外引流,内引流可作为治疗的最后选择。     

Surgical management of pancreatic trauma.

Ninety-one patients treated for pancreatic injuries are reviewed. Difficulty of diagnosis, including the surgical management of these injuries and their complications, are discussed in detail. The presence of associated multiple injuries, delay in diagnosis, and lack of sound surgical principles of treatment are directly proportional to the rate of complication and mortality.     

Mediastinal pancreatic pseudocyst.

Pseudocysts of the pancreas are a rare cause of a mediastinal mass. They are clinically characterized by the combination of thoracic symptoms (shortness of breath, dysphagia, pleural effusions) with complaints in the upper abdominal quadrants and weight loss. The diagnosis is usually made by CT scan or MRI including upper abdominal views. Internal drainage via an abdominal route performed either as cystogastrostomy or cystojejunostomy is the treatment of choice.     

Surgical management of pancreatic pseudocysts.

Pancreatic pseudocyst is a complication of pancreatitis or pancreatic trauma. A review of the experience with surgical treatment of pseudocyst of the pancreas at the University of Iowa was carried out. Pancreatitis associated with alcoholism accounted for a smaller percentage of the pseudocysts than is usually reported and reflects the nature of the population. Internal drainage of the pseudocyst obviates the development of pancreatic fistula which is often associated with external drainage; however, the mortality for each method of drainage was comparable.     

Multiple pancreatic pseudocyst disease.

In an effort to determine the incidence of multiple pseudocyst disease and establish the optimal approach to this problem, the records of 91 consecutive patients diagnosed during a 36-month period as having pancreatic pseudocyst disease by sonography or computerized tomographic scanning were reviewed. Thirteen patients (14.3%) had multiple cysts; all received sonograms and six had CT scans. The combined false negative and false positive rate with sonography was 9%. Spontaneous resolution occurred involving five cysts (18%) up to 6.5 cm in size. The diagnosis of cyst multiplicity was confirmed at operation in seven cases; two of the seven operations were excisional and the remaining patients received drainage procedures. There were no operative deaths; complications included one patient who required chronic enzyme replacement therapy after excision and another patient who developed a subphrenic abscess after attempted percutaneous drainage. The incidence of multiple pseudocyst disease in our series is just over 14%. The possibility of multiplicity should be carefully investigated in each patient with pseudocyst disease. In light of the rate of spontaneous resolution, not all patients with multiple pseudocysts may require operative therapy. Because of the 7.7% false negative diagnoses with sonography, CT scanning is especially helpful when the diagnosis of multiple pseudocysts is suspected or in preoperative preparation of pseudocyst drainage. If an operation becomes necessary, a drainage procedure rather than excision should be used whenever possible to maximize gland salvage.     

Endoscopic management of pancreatic pseudocyst in children-a long-term follow-up

Background

Literature on long-term outcome after endoscopic management of pediatric pancreatic pseudocyst is not available. The aim of the present study is to report long-term outcome after endoscopic drainage of pancreatic pseudocyst in children.

Methods

Nine patients younger than 15 years, subjected to endoscopic pseudocyst drainage, were included in this study (between 1994 and 2004). Eight patients were subjected to endoscopic cystogastrostomy and stenting, whereas 1 patient was subjected to cystoduodenostomy and stenting. A follow-up of patients was done at 1 month and at 2 to 10 years after drainage. Endoscopic retrograde cholangiopancreatography (ERCP) was done in 2 patients at the time of drainage, and it was repeated in both the patients at the time of final follow-up.

Results

Mean age of the patients was 9.6 years. Trauma was the most common cause (n = 8). Mean follow-up of these patients was 5.7 years (2-10 years). No recurrence was seen in any patient. Endoscopic retrograde cholangiopancreatography revealed complete pancreatic duct block in prevertebral region in 2 posttraumatic patients, and it was persisting on repeat ERCP at final follow-up.

Conclusions

Endoscopic drainage of pancreatic pseudocyst is safe in children with a very good long-term outcome. Pancreatic duct block seen on ERCP may not be clinically important on long-term follow-up.     

Operative strategies in the management of mediastinal pancreatic pseudocyst

Thirty-four cases of mediastinal pancreatic pseudocyst have been previously reported. Among the 32 previous reports with operative or autopsy analysis, communication has been identified in 30. Even when this communication has been quite small between the mediastinal fluid collection and the pancreas, the recommended operative strategy has been enteric drainage directly to this communicating tract. We report the case of a patient with a mediastinal pancreatic pseudocyst in whom the communication between the pancreas and the pseudocyst was not located. The condition was managed by drainage of the mediastinal pseudocyst with decompression of the main pancreatic duct by means of a longitudinal pancreaticojejunostomy in a patient with chronic pancreatitis.     

Blunt pancreatic trauma and pseudocyst: management of major pancreatic duct injury

When there is no major pancreatic duct injury or the injury involves only the distal duct, percutaneous drainage should be considered the primary therapeutic procedure for traumatic pancreatic pseudocyst. If the pseudocyst does not then resolve, endoscopic retrograde pancreatography should be performed to prove proximal duct injury. When the major pancreatic duct is disrupted but not obstructed, pancreatic duct stenting may avert surgical resection. If the major duct is obstructed, surgical resection is required.     

Surgical management of pancreatic lymphoma

The clinical and pathologic records of 12 patients with pancreatic lymphoma were reviewed retrospectively to determine distinguishing clinical features. Radiologically, all patients had large abdominal masses in the region of the pancreas. Preoperative percutaneous cytologic biopsy specimens failed to make the diagnosis, and two specimens were interpreted incorrectly as poorly differentiated adenocarcinoma. The diagnosis was difficult to make in two cases, even at laparotomy. Four patients underwent a biliary bypass, and two underwent a concomitant gastric or duodenal bypass. Two patients died postoperatively. Four patients responded well to chemotherapy and/or radiation therapy, and two did not have any recurrences at 3 and 7 years postoperatively. Although rare, lymphoma should be considered in patients with undiagnosed pancreatic masses. The diagnosis may only be made with appropriate preoperative or intraoperative suspicion, and treatment may be rewarding, particularly in comparison with pancreatic adenocarcinoma.     

Giant pancreatic pseudocyst

A 56 years old man presented with epigastric pain and abdominal distension. He suffered an attack of acute pancreatitis 6 weeks back followed by pseudopancreatic cyst formation. As the cyst kept on enlarging in size despite being on conservative management, the patient was operated after 5 weeks. A huge pancreatic pseudocyst was found containing about 4.5 liters of fluid. Cystogastrostomy was performed and the patient recovered un-eventfully. It was the third largest pancreatic pseudocyst reported so far.     

Spontaneous gastric decompression of pancreatic pseudocyst.

Spontaneous resolution of pancreatic pseudocysts is being reported with increasing frequency. Although many mechanisms have been proposed one that is not frequently recognized is spontaneous decompression into the gastrointestinal tract. This case report demonstrates the mechanism of spontaneous resolution of a traumatic pancreatic pseudocyst, several weeks after injury, through fistulization between the pseudocyst and the stomach. Spontaneous resolution of a pancreatic pseudocyst after a transient episode of diarrhea should suggest the mechanism of gastrointestinal decompression of the pseudocyst.
