Surgical management of pancreatic necrosis presenting with locoregional complications

[Acute necrotizing pancreatitis with hemorrhagic shock in secondary splenic rupture: a case report and literature review]

Atraumatic splenic rupture is a rare complication of acute and chronic pancreatitis. It arises due to its anatomical proximity to the pancreas, for instance, due to erosion of large pseudocysts or walled-of-necrosis (WON).Following we describe the case of a 62-year-old woman who presented for further diagnostics and treatment of acute pancreatitis with the development of large walled-of necrosis (WON) in the pancreatic corpus and tail. During the course, the patient developed a hemorrhagic shock. An emergency computer tomography (CT) of the abdomen revealed a ruptured spleen with a large capsular hematoma with no evidence of active bleeding. In contrast to previous published case reports, our treatment was exclusively minimal-invasive: by radiological guided embolization of the splenic artery and by endosonographic guided implantation of a lumen apposing metal stent (LAMS). The splenic hematoma was spontaneously regressive without secondary drainage.

Atraumatic Splenic Hemorrhage as a Rare Complication of Pancreatitis: Case Report and Literature Review

Splenic hemorrhage (hematoma and rupture) is a rare complication of pancreatitis. In this article, we present a rare case of spontaneous splenic rupture as a complication of acute pancreatitis. A literature review was also completed to describe the patient characteristics, associated pancreatitis etiology, clinical presentations, risk factors, diagnostic and treatment modalities, and outcomes.

Short-term outcomes from a multicenter retrospective study in China comparing laparoscopic and open surgery for the treatment of infected pancreatic necrosis

BACKGROUND

Laparoscopic surgery for confirmed infected pancreatic necrosis (IPN) represents a relatively new solution. There are no studies comparing the outcomes of laparoscopic and open surgery for patients with IPN. The aims of this study were to investigate the feasibility of laparoscopic management for patients with IPN and to compare the outcomes of laparoscopic and open surgery.

METHODS

Seventy-six patients with IPN who underwent open surgery (Open-group) or laparoscopic surgery (Lap-group) were retrospectively reviewed. Demographic data, white blood cell count, and APACHE II score upon admission, operative findings, major complications, and mortality were compared between the Open-group and the Lap-group. The Lap-group was further divided into two subgroups (early and late), and the operative difficulty was compared between the two subgroups.

RESULTS

There were no significant differences between the Open-group and the Lap-group with respect to demographic data, white blood cell count, and APACHE II score. Although the mean operative time was significantly shorter in the Open-group than in the Lap-group, the estimated blood loss was significantly greater in the Open-group than in the Lap-group, as was the rate of complications. The mean postoperative hospital stay in the Open-group was significant longer than in the Lap-group, too. In the Lap-group, the mean operating time, estimated blood loss, and conversion rate in the early subgroup were significantly lower than in the late subgroup.

CONCLUSION

Laparoscopic necrosectomy and the placement of an intermittent irrigation and continuous suction drainage system for IPN is feasible, effective, and of minimal invasiveness. The late laparoscopic necrosectomy is relatively difficult.

Outcome after pancreatic necrosectomy: trends over 12 years at an Indian centre

BACKGROUND

Pancreatic necrosectomy for necrotizing pancreatitis is a formidable operation. There are limited data from the Indian subcontinent regarding outcome and recent trends in management.

METHODS

Patients undergoing pancreatic necrosectomy over a 12-year period were identified from a prospective database. Data regarding the hospital course, complications and outcome were extracted by case file review. Descriptive statistics were used to present the data. An attempt was made to identify trends in management and outcome over the study period.

RESULTS

One hundred and eighteen patients underwent necrosectomy. The median age was 39.5 years (interquartile range, 32-46). Median Acute Physiology And Chronic Health Evaluation II score at admission was 8 (interquartile range, 6-10). Thirty-nine patients (33%) had organ failure at admission. Patients underwent surgery a median of 23 days (interquartile range, 14-34) after onset of illness. There was high incidence of loco-regional complications (68/118, 58%) and organ failure (88/118, 75%) in the postoperative period. The mortality rate was 38%. There was an increase in the median onset to surgery interval (17 vs 25.5 days; P = 0.001), increased use of percutaneous interventions (20 vs 36%; P = 0.05) and decreased mortality (47 vs 29%; P = 0.052) in the later half of the study period.

CONCLUSION

Pancreatic necrosectomy continues to be associated with significant morbidity and mortality in India. A trend towards increased use of percutaneous interventions and delayed surgery is evident.

Long-term results and quality of life of patients undergoing sequential surgical treatment for severe acute pancreatitis complicated by infected pancreatic necrosis

BACKGROUND

Infected pancreatic necrosis (IPN) is one of the most severe complications of acute pancreatitis (AP). Sequential surgical debridement represents one of the most effective treatments in terms of morbidity and mortality. The aim of this paper is to describe the quality of life and long-term results (e.g., nutritional, muscular, and pancreatic function) of patients treated by sequential necrosectomy at the Department of Surgery of the University of Insubria (Varese, Italy).

METHODS

Data were collected on patients undergoing sequential surgical debridement as treatment for IPN. The severity of AP was evaluated using the Ranson criteria, the Acute Physiology and Chronic Health Evaluation (APACHE II) Score, and the Sepsis Score, as well as the extent of necrosis. The surgical approach was through a midline or subcostal laparotomy, followed by exploration of the peritoneal cavity, wide debridement, and peritoneal lavage. The abdomen was either left open or closed partially with a surgical zipper, with multiple re-laparotomies scheduled until debridement of necrotic tissue was complete. The long-term evaluation focused on late morbidity, performance status, and abdominal wall function.

RESULTS

In the majority of patients (68%), mixed flora were isolated. Pseudomonas aeruginosa was the microorganism identified most commonly (59%), often associated with Candida albicans or C. glabrata. The mean total hospital stay was 71+/-38 days (range 13-146 days), of which 24+/-19 days (range 0-66 days) were in the intensive care unit. Eight patients died, the deaths being caused by multiple organ dysfunction syndrome in seven patients and hemorrhage from the splenic artery in one. Normal exocrine and endocrine pancreatic function was observed in 28 patients (88%). At discharge, four patients had steatorrhea, which was temporary. Eight patients (23%) developed pancreatic pseudocysts, and in six, cystogastostomy was performed. Most patients (29/32, 91%) developed a post-operative hernia, but only five required surgical repair. All patients had a Short Form (SF)-36 score>60%, and 20 of the 32 patients (68%) had scores>70-80% (good quality of life). The worst scores were related to alcoholic pancreatitis.

CONCLUSIONS

The degree of pancreatic failure (exocrine and endocrine function) is not related to the amount of pancreatic necrosis. Even with a need for repeated laparotomy and multiple surgical procedures, the abdominal wall capacity as well as long-term quality of life remain excellent.

JPN Guidelines for the management of acute pancreatitis: surgical management

Acute pancreatitis represents a spectrum of disease ranging from a mild, self-limited course to a rapidly progressive, severe illness. The mortality rate of severe acute pancreatitis exceeds 20%, and some patients diagnosed as mild to moderate acute pancreatitis at the onset of the disease may progress to a severe, life-threatening illness within 2–3 days. The Japanese (JPN) guidelines were designed to provide recommendations regarding the management of acute pancreatitis in patients having a diversity of clinical characteristics. This article sets forth the JPN guidelines for the surgical management of acute pancreatitis, excluding gallstone pancreatitis, by incorporating the latest evidence for the surgical management of severe pancreatitis in the Japanese-language version of the evidence-based Guidelines for the Management of Acute Pancreatitis published in 2003. Ten guidelines are proposed: (1) computed tomography-guided or ultrasound-guided fine-needle aspiration for bacteriology should be performed in patients suspected of having infected pancreatic necrosis; (2) infected pancreatic necrosis accompanied by signs of sepsis is an indication for surgical intervention; (3) patients with sterile pancreatic necrosis should be managed conservatively, and surgical intervention should be performed only in selected cases, such as those with persistent organ complications or severe clinical deterioration despite maximum intensive care; (4) early surgical intervention is not recommended for necrotizing pancreatitis; (5) necrosectomy is recommended as the surgical procedure for infected pancreatic necrosis; (6) simple drainage should be avoided after necrosectomy, and either continuous closed lavage or open drainage should be performed; (7) surgical or percutaneous drainage should be performed for pancreatic abscess; (8) pancreatic abscesses for which clinical findings are not improved by percutaneous drainage should be subjected to surgical drainage immediately; (9) pancreatic pseudocysts that produce symptoms and complications or the diameter of which increases should be drained percutaneously or endoscopically; and (10) pancreatic pseudocysts that do not tend to improve in response to percutaneous drainage or endoscopic drainage should be managed surgically.

The usefulness of early laparoscopic surgery for determining a medical treatment plan in severe acute pancreatitis

A 41-year-old woman presented with sudden onset severe epigastric pain. She was diagnosed as having severe acute pancreatitis (SAP) with an APACHE II score of 10, and initially, general supportive therapy was performed. Because the patient's condition kept worsening, early laparoscopic surgery was performed. It revealed swelling, hemorrhagic necrosis of the pancreas, and massive fluid collection in the abdominal cavity. Kocherization and bursectomy were performed for these lesions, and drainage tubes were indwelled. The white blood cell count (WBC) and serum interleukin-6 value prominently improved shortly after the operation, and the WBC count remained at a low level. The patient gradually recovered and was finally discharged 39 days after her initial presentation. To summarize, we performed a successful exploration for SAP, and we found that postoperative continuous lavage effectively eliminated toxic enzymatic exudates in the abdominal cavity and prevent them from circulating. Regarding SAP with peritonitis, early laparoscopic surgery is very useful for determining the pathological extent of the disease and for selecting appropriate treatment options.

Necrosis of the duodenum resulting from acute necrotising pancreatitis and treated with complete duodenopancreatectomy

Necrosis of the duodenum resulting from acute necrotising pancreatitis is a rare but potentially lethal complication. A small number of cases has been reported so far, the majority of which having, unfortunately, had a lethal outcome. We present the cases of two patients, a 21-year-old woman and a 54- year-old man, both suffering from extensive duodenal necrosis stemming from acute necrotising pancreatitis, and both cases involving the second and third sections of the duodenum, one of which was probably caused by the thrombosis of nutritive blood vessels, the other by an abscess of the head of the pancreas. Due to the extent of the necrosis of the duodenum, there was no option to close so large a hole or to employ any less drastic procedure, so that a complete duodenopancreatectomy had to be performed. One patient survived and has remained in good health for a period of almost ten years, to date. The other patient died six days after surgery due to infection, in spite of an absence of any sort of anastomic complications.

Pneumoperitoneum from gas gangrene of the pancreas: three unusual findings in a single case

A 62-year-old man was first seen with acute pancreatitis with diffuse intrapancreatic gas and pneumoperitoneum. An immediate exploratory operation revealed diffuse pancreatic necrosis but no perforated viscus; postoperatively, the patient rapidly died. This case represents a constellation of extremely rare findings: Clostridium perfringens infection of the pancreas, pancreatic emphysema or "gas gangrene," and pneumoperitoneum without a perforated viscus.

Laparoscopic management of severe acute pancreatitis

INTRODUCTION

Severe acute pancreatitis (SAP) remains a serious disease state difficult to manage. Laparoscopic surgery represents a relatively new solution to this problem. This study was aimed to investigate the feasibility of laparoscopic treatment of SAP and the selection of laparoscopic procedures in various stages of SAP according to different pathologic alterations.

METHODS

Thirteen patients, 9 men and 4 women with an average age of 46 years old, were diagnosed with SAP. Laparoscopic necrosectomy followed by external drainage were performed on 7 patients with massive fluid collections and/or infected necrosis in acute reaction phase of SAP. For 2 cases in subacute phase characterized by fresh-formed adhesions and encapsulation, laparoscopic intracavitary debridement experienced difficulty. For the other 4 patients in late phase with well-defined pancreatic or peripancreatic pseudocyst/abscess, ultrasound-guided, directly visualized laparoscopic intracavitary debridement, and external drainage were carried out with ease and efficiency.

RESULTS

Laparoscopic procedures were accomplished successfully on 12 patients (92.3%), except for 1 conversion (7.7%) to open laparotomy owing to poor exposure and hard maneuvers in subacute phase. There was no mortality in this group. Patients were witnessed to have accelerated recovery following laparoscopic surgery.

CONCLUSION

Laparoscopic technique offers new hope for the treatment of SAP. It is recommended as a feasible, effective, and less traumatic therapeutic means on condition that the strategy of individualization is followed.

Laparoscopic treatment of severe acute pancreatitis

BACKGROUND

The appropriate surgical treatment for severe acute pancreatitis has been disputed for a long time. Herein we describe our experience with the laparoscopic treatment of this disease.

METHODS

Ten patients, seven male and three female, with an average age of 55 years were diagnosed with severe acute pancreatitis. All cases but one were found to be without biliary stones by ultrasonic and CT scans. Laparoscopic exploration, irrigation, drainage, and decompression of the pancreas were performed. Further treatment, including gastric decompression, irrigation via the drainage tubes, antibiotics, somatostatin, and parenteral nutrition, was continued in all patients following the laparoscopic procedures.

RESULTS

Nine patients recovered successfully; one died from adult respiratory distress syndrome (ARDS) soon after the operation. The hospital stay was 10-30 days.

CONCLUSIONS

The laparoscopic era offers new hope for the treatment of severe acute pancreatitis. The technique can be used to determine the pathologic extent of the disease, to irrigate and drain the abdominal cavity, and to decompress the pancreas. Almost every surgical procedure for acute pancreatitis can be performed laparoscopically.
