Abdominal operations in patients with cirrhosis: Still a major surgical challenge☆

BACKGROUND Hepatic transplantation and portasystemic shunts can be safely performed in patients with advanced liver disease, whereas other abdominal procedures appear to have a much higher mortality rate. This study reviews the outcomes of patients with cirrhosis after the full spectrum of abdominal operations. METHODS In a 12-year period, 92 patients diagnosed with cirrhosis required either an emergent or elective abdominal operation. There were four categories of operations: cholecystectomy in 17 patients, hernia in 9, gastrointestinal tract in 54, and other procedures in 12. Fifty-five clinical, laboratory, and operative variables were analyzed to identify factors predictive of poor outcome. RESULTS Coagulopathy developed in 24 patients (27%) and sepsis in 15 (16%). The mortality rate after emergent operations was 50%, compared to 18% for elective cases (p = 0.001). Other factors that predicted mortality included the presence of ascites (p = 0.006), encephalopathy (p = 0.002), and elevated prothrombin time (p = 0.021). The mortality in Childs class A patients was 10%, compared to 30% in class B and 82% in class C patients. CONCLUSIONS Patients with cirrhosis undergoing elective or emergent operations are at a significant risk of developing postoperative complications leading to death. The most accurate predictor of outcome is the patients preoperative Childs class.

Treatment of pancreatic cutaneous fistulas with asomatostatin analog

Five pancreatic cutaneous fistulas were treated by subcutaneous administration of a long-acting synthetic analog of somatostatin, SMS 201-995. Patients included four men and one woman who ranged in age from 52 to 77 years. The fistulas developed after drainage of a pancreatic abscess, biopsy of a pancreatic mass, splenectomies for idiopathic thrombocytopenic purpura and Feltys syndrome, and operative trauma, respectively. Fistula output consisted of 1,000 ml/day of amylase- and lipase-rich fluid in the patient with a pancreatic biopsy. The other four patients had low-output fistulas (100 to 250 ml/day) that had been draining for 1 to 12 months. Direct communication with the pancreatic duct was demonstrated by endoscopic retrograde cholangiopancreatography, sinography, or both in four of the five patients. Fistula output decreased from 340 +/- 376 ml/day to 63 +/- 36 ml/day on the first day of therapy with two daily doses of 0.05 mg SMS 201-995 (p less than 0.03) and to 13 +/- 19 ml/day on the seventh day of therapy (p less than 0.03). Two patients had prompt closure of their fistulas and one closed in 3 months. One patient with chronic pancreatitis and a duct stricture and one patient with recurring infection did not achieve permanent fistula closure with SMS 201-995. Because of its safety, ease of administration, and efficacy in decreasing fistula output, we believe somatostatin analog therapy is beneficial in hastening closure of pancreatic fistulas.

A Comparison of Pancreaticogastrostomy and Pancreaticojejunostomy Following Pancreaticoduodenectomy

This retrospective study compares the results of pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ) in our institution, which has extensive experience in both techniques. Between the years of June 1995 and June 2001, 214 patients underwent pancreaticoduodenectomy (PD) at our institution. Of these 177 had PG and 97 had pancreatojejunostomy (PJ). There were 117 (54.6%) males and 97 (45.3%) females with a mean age of 64.2 ± 12.4 years. Indications for surgery were pancreatic adenocarcinoma in 101 (47.2%), ampullary adenocarcinoma in 36 (16.9%), distal bile duct adenocarcinoma in 22 (10.2%), duodenal adenocarcinoma in 9 (4.2%), and miscellaneous causes in 46 (21.4%) of patients. Preoperatively, significant differences in the groups were that the patients undergoing PJ were significantly younger than those undergoing PG. Also noted preoperatively, was that the patients undergoing PG had a significantly lower direct bilirubin than those undergoing PJ. With regard to intraoperative parameters, operative time was significantly shorter in the PJ group when compared to the PG group. When the patients who did not develop fistula (N = 186) were compared to those who developed fistula (N = 28) the significant differences were that the patients who developed fistula were more likely to have hypertension preoperatively and a higher alkaline phosphatase. They also showed a significantly higher drain amylase and were likely to have surgery for ampullary, distal bile duct or duodenal carcinoma rather than pancreatic adenocarinoma. In addition, those patients who developed fistula had a significantly longer postoperative stay, a larger number of intraabdominal abscesses and leaks at the biliary anastomosis. Thirty-day mortality was significantly higher in the PJ group compared to the PG (4 vs. 0, P = 0.041). There was a significantly larger number of bile leaks in the PJ group when compared to the PG (6 vs. 1, P = 0.048). In addition, the PJ group required a significantly larger number of new CT guided drains to control infection (8 vs. 2,P = 0.046) and the PJ group required a larger number of re-explorations to control infection or bleeding (5 vs. 0, P = 0.018). However, the pancreatic fistula rate was not different between the two groups (12% [PG] vs. 14% [PJ]). This retrospective analysis shows that safety of PG can be performed safely and is associated with less complications than PJ and proposes PG as a suitable and safe alternative to PJ for the management of the pancreatic remnant following PD.

Pancreaticogastrostomy following pancreaticoduodenectomy: review of 102 consecutive cases.

Abstract. Disruption of the pancreatic anastomosis with resultant sepsis is the cause of nearly 50% of deaths following pancreaticoduodenectomy (PD). Traditionally, the pancreatic remnant is anastomosed to the jejunum. Pancreaticogastrostomy (PG) was introduced as an alternative by Waugh and Clagett in 1946 and by Park, Mackie, and Rhoads in 1967. The purpose of this retrospective review was to assess the safety of PG at a single institution. Between 1986 and 1998 a total of 102 patients underwent PG following PD. The indications for PD were periampullary carcinoma (n= 89), pancreatitis (n= 7), and miscellaneous (n= 6). Altogether, 80 patients underwent the traditional Whipple procedure and 22 the pylorus-preserving Whipple (PPW) procedure. The PG was performed by a single-layer invagination technique to the posterior gastric wall using interrupted silk sutures. Leaks from the pancreatic anastomosis were detected by measuring amylase in fluid obtained from surgically placed drains. Operative mortality was 3.9% (4/102). The cause of death was uncontrolled upper gastrointestinal hemorrhage, sepsis, pulmonary embolus, and cardiac failure secondary to myocardial infarction. The mean operating time was 6.8 hours. Blood transfusion was given in 43 patients (42%), and the mean amount of the transfusion was 2.6 units. Nonfatal complications occurred in 35 patients (34%), and included leaks from the pancreatic anastomosis in 9 (8.8%), leaks from the biliary-enteric anastomosis in 4 (3.9%), and gastric paresis 7 (6.9%). Other complications included abscess, wound infection, colitis, delirium tremens, and hyperbilirubinemia. Discharge occurred 6 to 47 days (median 12 days) postoperatively and was prolonged in patients suffering from a complication. PD is associated with significant morbidity. PG is a safe alternative to pancreaticojejunostomy for managing the pancreatic remnant.

Surgical significance of extrahepatic biliary tree anomalies

A patient with an anomalous insertion of the right hepatic duct into the cystic duct was noted during cholecystectomy and confirmed by operative cholangiography. This case and related anomalies of the bile ducts are of sufficient importance that, because of the technical difficulties and dangers incidental to their presence, no surgeon who operates on the gallbladder and bile ducts can afford to be unaware of their existence. Adequate exposure, careful dissection, and accurate knowledge of the regional anatomy plus a realization of the frequency and multiplicity of abnormalities of the extrahepatic biliary tree are requisites for safe biliary tract surgery. In addition, carefully performed operative cholangiography can be an indispensable aid in the clarification of anatomic variations. In case of recognized operative injury to the extrahepatic biliary tree, primary repair or biliary-intestinal anastomosis can usually be carried out with good results.

Primary Malignant Melanoma of the Common Bile Duct A Case Report and Review of the Literature

Primary malignant melanoma of the common bile duct is rare. To our knowledge, only 6 cases have been reported previously. The pathologic diagnosis of primary malignant melanoma in extracutaneous sites often requires the use of confirmatory immunohistochemical stains and electron microscopy studies, as well as tests to rule out other possible remote or concurrent primary sites. The presence of junctional activity adjacent to the tumor is another important requisite for the diagnosis of this entity. Nevertheless, absolute exclusion of a metastatic melanoma from an unknown occult site or regressed site is not entirely possible. We describe our observations in a case of primary malignant melanoma of the common bile duct in a 48-year-old man and discuss the criteria for diagnosis of primary melanoma.

Parapubic hernia following radical retropubic prostatectomy

We report a parapubic hernia in a 54-year-old patient following radical retropubic prostatectomy. This complication can occur when the musculotendinous insertions of the rectus abdominis muscle are divided from the pubis. Bowel contents herniate over the pubic crest and can be misdiagnosed as an incisional or inguinal hernia. Successful repair depends on closure of the entire defect. Elective repair necessitates the use of prosthetic mesh.

Age is not a contraindication to pancreaticoduodenectomy

The incidence of pancreatic cancer has increased threefold over the last 40 years with the greatest rate of growth occurring in the elderly. In the past it was suggested that elderly patients tolerated pancreaticoduodenectomy less well than younger patients with higher mortality rates. This single-institution experience examines the question of whether age is a significant factor in relation to morbidity and mortality in patients undergoing pancreaticoduodenectomy. Between 1994 and 1999 outcomes of 122 patients who underwent pancreaticoduodenectomy were reviewed. There were 48 patients 70 years of age and older and 74 patients less than 70 years of age. Both groups were compared with respect to preoperative clinical prognostic determinates and perioperative factors affecting morbidity and mortality. There was no significant difference between the two groups comparing their comorbidities, use of preoperative antibiotics, intraoperative blood loss, or length of hospital stay (11.9 and 10.8 days respectively). The two groups were also similar with regard to pathologic diagnosis with pancreatic adenocarcinoma being the most frequently encountered neoplasm. There was one death in the less-than-70-year-old group and none in the older group. No significant difference in the rate of complications was appreciated. These data demonstrate that pancreaticoduodenectomy can be performed safely in patients 70 years of age and older with morbidity and mortality rates similar to those of younger individuals.
