Risk factors associated with urinary tract infection within 4 days of male rectal cancer surgery in the era of enhanced recovery after surgery (ERAS) programs.

BACKGROUND: Bladder drainage is systematically used in rectal cancer surgery in male patients, even in the era of enhanced recovery after surgery (ERAS). However, little data is available on risk factors for urinary tract infection (UTI). Identifying the risk factors associated with UTI within 4 days of male rectal cancer surgery in an ERAS program could support more individualized decision-making. METHODS: We used data from the GRECCAR 10 randomized clinical trial, a comparison of outcomes of transurethral catheterization (TUC) or suprapubic catheterization (SPC). 240 patients were randomized, 209 retained in the study (TUC n = 99; SPC n = 109). Univariate and multivariate logistic regression post-hoc study analyses were performed to assess association between potential predictive factors and UTI within 30 days after surgery. RESULTS: Out of 208 patients (median age 64.5 years), 19 (9.1%) had UTI, 26 (12.5%) had bacteriuria and 145 (69.7%) had pyuria. Univariate analysis identified age ≥ 65 years (OR = 3.08 [1.07-8.89]; p = 0.038), hypertension (OR = 3.65 [1.23-10.84]; p = 0.020) and ASA score ≥ 3 (OR = 4.15 [1.53-11.2]; p = 0.005) as risk factors for UTI until POD4. Multivariate analysis identified ASA score ≥ 3 with a risk of UTI. CONCLUSION: Regarding male rectal cancer surgery, our study shows that nearly 1 in 10 patients had UTI within 4 days. An ASA score ≥ 3 is an independent risk factor linked to UTI. Identifying this risk factor for UTI is necessary to advise patients, support a tailored decision-making process, and prevent these complications.

Liver repopulation trial using bone marrow cells in a retrorsine-induced chronic hepatocellular injury model.

OBJECTIVES: The aim of this study was to determine the potential of bone marrow derived cells to participate in liver repopulation. In this model, the injected cells had a "selective growth advantage" compared to the native hepatocytes whose proliferation was blocked by retrorsine. METHODS: Total bone marrow cells were isolated from male Fisher 344 rats not deficient in dipeptidyl peptidase activity (F344, DPP IV+). The animals were given an injection of retrorsine and were divided in 2 groups: 1/group R (N=13): female F344 rats received 4.106 male cells at day 0 (labeled by chromosome Y). 2/group RH (N=19): Male F344 DPP IV- rats received 4.106 male DPP IV+ cells after hepatectomy at day 0 (labelled by DPP IV activity). RESULTS: Group R: no male cell was detected by PCR at day 14, 28, 56 and 84. Group RH: isolated DPP IV+ transplanted cells were observed at days 14 and 28 in the periportal areas. Later, these cells were no longer visible. Liver regeneration occurred by proliferation of small clusters of hepatocytes. CONCLUSIONS: In this experimental model the capacity of transplanted bone marrow cells to repopulate the liver was tested against the same capacity of native liver stem cells. Liver regeneration occurred via native liver cells seen as small hepatocytes. In this model the small hepatocytes may be considered as hepatic stem cells.

[Delayed recurrence of an endobiliary hepatocellular carcinoma without detectable intra-parenchymatous tumor].

Obstructive jaundice is uncommon in patients with hepatocellular carcinoma. It can be due to compression of the common bile duct by the liver tumor or by enlarged lymph node metastases in the porta hepatis. Obstructive jaundice can also be due to direct extension of hepatocellular carcinoma into the bile ducts with or without a detectable primary hepatic tumor. These particular hepatocellular carcinoma have been termed "icteric type hepatoma" by Lin et al. in 1975, who emphasized their poor prognosis. We report a similar case of endobiliary hepatoma without a detectable intraparenchymal hepatic tumor in a seventy year-old man. This case is unusual because of its positive evolution and late recurrence.

Frey procedure in the treatment of chronic pancreatitis: short-term results.

OBJECTIVE: The aim of this multicenter study was to report the short-term results of the Frey procedure in the treatment of chronic pancreatitis. METHODS: For the period between September 2000 and January 2005, 34 Frey procedures were performed for chronic pancreatitis in 4 university hospitals. This study includes 31 men (91%) and 3 women (9%), with a mean age of 48 +/- 6 years (range, 32-58 years). The etiology of chronic pancreatitis was chronic alcohol ingestion in 32 patients (94%) and hereditary chronic pancreatitis in 2 patients. The indications of surgery were abdominal pain in all patients, requiring opiates in 59% (n = 20) and associated with a weight loss in 79% (n = 27). RESULTS: There was no mortality. Eleven postoperative surgical complications occurred in 7 patients (20%). Three patients had a single complication, and 4 patients had 2 complications. Pancreatic fistula occurred in 4 patients and healed under conservative management in all cases. One patient had massive bleeding from the stump of gastroduodenal artery requiring reoperation. The mean hospital stay was 16 +/- 8 days (range, 9-40 days). The mean follow-up was 15 +/- 12 months (range, 3-37 months). At the time of the last follow-up visit, the examiner judged that 19 patients (56%) have complete pain relief and 11 patients (32%) have substantial pain relief. No patient used narcotic analgesics postoperatively. Seven patients developed diabetes mellitus, requiring insulin (n = 1), oral hypoglycemic agents (n = 5), and diet adjustment (n = 1). Four patients developed exocrine insufficiency. Weight increases with a mean of 4.8 +/- 5.4 kg (range, 1-24 kg) in 27 patients (79%). CONCLUSIONS: Frey procedure appears as a safe technique with low mortality and morbidity rates and allows effective pain relief in about 90% of patients.

Is hepatic resection for large or multinodular hepatocellular carcinoma justified? Results from a multi-institutional database.

BACKGROUND: The role of surgical resection in patients with large or multinodular hepatocellular carcinoma (HCC) remains unclear. This study evaluated the long-term outcome of patients with hepatic resection for large (>5 cm in diameter) or multinodular (more than three nodules) HCC by using a multi-institutional database. METHODS: The perioperative and long-term outcomes of 404 patients with small HCC (<5 cm in diameter; group 1) were compared with those of 380 patients with large or multinodular HCC (group 2). The prognostic factors in the latter group were analyzed. RESULTS: The postoperative complication rate (27% vs. 23%; P = .16) and hospital mortality rate (2.4% vs. 2.7%; P = .82) were similar between groups. The overall survival rates were significantly higher in group 1 than group 2 (1 year, 88% vs. 74%; 3 years, 76% vs. 50%; 5 years, 58% vs. 39%; P < .001). Among patients in group 2, five independent prognostic factors were identified to be associated with a worse overall survival: namely, symptomatic disease, presence of cirrhosis, multinodular tumor, microvascular tumor invasion, and positive histological margin. CONCLUSIONS: Hepatic resection can be safely performed in patients with large or multinodular HCC, with an overall 5-year survival rate of 39%. Symptomatic disease, the presence of cirrhosis, a multinodular tumor, microvascular invasion, and a positive histological margin are independently associated with a less favorable survival outcome.

Benign hilar biliary strictures stented with metallic stents can be resected by using an oncologic approach.

BACKGROUND: Biliary metallic stents (MS) are being used increasingly to treat patients with malignant bile duct strictures. In patients with benign strictures, MS are contraindicated because these stents are considered unremovable. The aim of this study was to report the operative treatment of patients with benign biliary strictures at the hepatic confluence stented with MS. METHODS: Five patients with a benign hilar stenosis stented with MS underwent liver resection with biliodigestive anastomoses. The operations were designed to remove all MS by a combined biliary and hepatic resection. RESULTS: After preoperative portal vein embolization in 2 patients and percutaneous biliary drainage in 2 others, all underwent a major hepatectomy with resection of the biliary confluence and a biliodigestive anastomosis. One patient also underwent resection of the portal vein bifurcation that could not be freed from the bile duct wall. Four patients experienced postoperative complications. With a mean follow-up of 37 months (range, 31-47 months), all patients have remained symptom-free. CONCLUSIONS: Operative treatment of benign hilar strictures in patients with MS is possible if they are managed similarly as patients with hilar malignancies. This demanding procedure should be considered an alternative to liver transplantation for benign strictures treated with MS, but the procedure requires expertise in advanced hepatic resections.

[Osteoclastic giant cell tumour of the pancreas].

Osteoclast giant cell tumours are bone tumours that occur in adults, and that are considered benign by WHO but locally aggressive. Strictly identical tumours are described in the pancreas, without simultaneous bone localization. We report the case of a 62-year woman with an osteoclast giant cell tumour of the distal pancreas, without any epithelial component, which was diagnosed after pancreatic resection and with no signs of recurrence after a 24-month follow-up. These pancreatic tumours are rare, with a very poor prognosis, an unclear histogenesis; they are often confused with pleomorphic or undifferentiated pancreatic carcinomas including a component of osteoclast giant cell. These osteoclast giant cell tumours of the pancreas usually present as large cystic tumours. In certain cases, complete resection can result in long-term survival.

Endoscopic treatment of chronic pancreatitis.

OBJECTIVES: Endoscopy offers an alternative to surgery for the treatment of ductal complications in patients with chronic pancreatitis. The aim of this study was to evaluate the efficacy of endoscopic treatment on pain, cholestasis and pseudocysts in these patients. PATIENTS AND METHODS: Thirty-nine patients (37 M, 2 F, mean age 44), were included in the study. All patients had at least one of the following criteria demonstrated by imaging tests: dilatation of the main pancreatic duct (MPD) with or without stricture (N = 13), bile duct stricture (N = 12), or pancreatic pseudocyst (N = 14) with pancreatic duct stricture (N = 11) or biliary stricture (N = 3). Pancreatic or biliary sphincterotomy, insertion of pancreatic or biliary stent, pseudocyst drainage with stent placement were performed according to ductal abnormalities. Patients were evaluated early and followed up during the stenting period, and after stent removal. RESULTS: Patients underwent a median of 3.5 endoscopic procedures with an interval of 2.2 months between 2 stenting sessions. A pancreatic or biliary stent was inserted in 25 patients with ductal abnormalities and in 11 patients with pseudocysts. Endoscopic pseudocyst drainage was performed in 6 cases. The mean stenting time was 6 months (range: 3-21). Mean follow-up after stent removal was 9.7 (2-48) months. Complications of endoscopic treatment were encountered in 7% of patients with no deaths. Pain relief was achieved after the first endoscopic procedure and during the overall stenting period in all patients. Recurrence of pain was observed after stent removal in 5/11 patients, requiring surgery in 4. Cholestasis decreased and biochemical values normalized within one month after biliary stenting. Recurrence of cholestasis was observed early after stent removal in 4/9 patients who required complementary surgical treatment. No recurrence of pancreatic pseudocyst was observed after endoscopic drainage and stent removal during the follow-up period. CONCLUSIONS: Endoscopic treatment of pain from pancreatic pseudocysts or ductal strictures is effective in the short-term and in the period of ductal stenting. However, the optimal duration of the latter remains to be determined.

Groove pancreatitis and pancreatic heterotopia in the minor duodenal papilla.

Groove pancreatitis is a rare form of segmental chronic pancreatitis that involves the anatomic space between the head of the pancreas, the duodenum, and the common bile duct. We report 2 cases of groove pancreatitis with pancreatic heterotopia in the minor papilla. Patients were a 44-year-old woman and a 47-year-old man. Both had a past history of alcohol consumption and presented with abdominal pain, vomiting, and weight loss caused by duodenal stenosis. Abdominal computed tomography revealed thickening of the duodenal wall and enlargement of the pancreatic head in both patients. In 1 patient, ultrasound endoscopy showed a dilated duct in the head of the pancreas. Pancreaticoduodenectomy was performed to rule out pancreatic adenocarcinoma and because of the severity of the symptoms. In both cases, gross and microscopic examinations showed fibrous scar of the groove area. The Santorini duct was dilated and contained protein plugs in both patients, with abscesses in 1 of them. In both cases, there were microscopic foci of heterotopic pancreas with mild fibrosis in the wall of the minor papilla. Groove pancreatitis is often diagnosed in middle-aged alcoholic men presenting with clinical symptoms caused by duodenal stenosis. The pathogenesis of this rare entity could be because of disturbance of the pancreatic secretion through the minor papilla. Pancreatitis in heterotopic pancreas located in the minor papilla and chronic consumption of alcohol seem to be important pathogenic factors.

Sinistroposition of the gallbladder and common bile duct.

BACKGROUND: Despite its rare incidence, few cases of left-side gallbladder have been already published. METHODS: We reported herein the case of a 29-year-old man with a left liver tumor in whom left lateral bisegmentectomy was mandatory. It represents the first description of a sinistroposition of both gallbladder and common bile duct. RESULTS: Surgical exploration revealed a left-side gallbladder, located under the left lobe of the liver. During hepatic parenchyma dissection at the left side of the round ligament and the Rex recessus, the common bile duct was injured. Complete separation of hepatic pedicle structures showed that the upper biliary convergence passed on the left side of the Rex recessus before reaching the hepatoduodenal ligament. CONCLUSION: Only careful dissection of the hepatoduodenal ligament up to Rex recessus level prior to liver parenchyma resection could avoid biliary tract injury during left lobectomy.

Reconstruction of portal vein using a hepatic vein patch graft after combined hepatectomy and portal vein resection.

BACKGROUND: Surgical resection is the only treatment modality that ensures complete tumor removal in patients with liver tumors involving a major portal vein branch or its bifurcation. Restoration of good portal blood flow is essential for recovery in the early postoperative period and for long-term survival. However, such extended resections often result in large defects at the bifurcation of the portal vein that are not amenable to suturing or end-to-end anastomosis. METHODS: A patch graft technique is very useful for reconstruction of long and elongated defects when other methods are not technically appropriate. We describe a simple technique for reconstructing the portal vein using a patch graft obtained from the hepatic vein stump of the resected specimen. CONCLUSIONS: This technique permits surgeons to reconstruct the portal vein without any need for harvesting another vein and with no need for an additional incision.

The small remnant liver after major liver resection: how common and how relevant?

The maximum extent of hepatic resection compatible with a safe postoperative outcome is unknown. The study goal was to determine the incidence and impact of a small remnant liver volume after major liver resection in patients with normal liver parenchyma. Among 265 major hepatectomies performed at our institution (1998 to 2000), 138 patients with normal liver and a remnant liver volume (RLV) systematically calculated from the ratio of RLV to functional liver volume (FLV) were studied. Patients were divided into five groups based on RLV-FLV ratio from </=30% to >/=60%. Kinetics of postoperative liver function tests were correlated with RLV. Postoperative complications were stratified by RLV-FLV ratios. Ninety patients (65%) underwent resection of up to four Couinaud segments. The RLV-FLV ratio was </=60% in 94 patients (68%) including only 13 (9%) with RLV-FLV </=30%. There was no linear correlation between the number of resected segments and the RLV-FLV. Postoperative serum bilirubin but not prothrombin time correlated with extent of resection. The incidence of complications including liver failure was not different among groups. Analysis of the four groups with a RLV-FLV ratio <60% showed a trend toward more complications and a longer intensive care unit stay in patients with the smallest RLVs. After major hepatectomy in patients with normal livers, the proportion of patients with a small remnant liver is low and not directly related to the number of segments resected. Although the rate of postoperative complications, including liver failure, did not directly correlate with the volume of remaining liver, the postoperative course was more difficult for patients with smaller remnants. Therefore preoperative portal vein embolization should be considered in patients who will undergo extended liver resection who have (1) injured liver or (2) normal liver when the planned procedure will be complex or when the anticipated RLV-FLV will be <30%.

Comparison of clinicopathologic characteristics and outcomes after resection in patients with hepatocellular carcinoma treated in the United States, France, and Japan.

OBJECTIVE: To compare the clinicopathologic characteristics and outcomes after resection of patients with hepatocellular carcinoma (HCC) treated in the United States, France, and Japan. SUMMARY BACKGROUND DATA: Some epidemiologic data suggests that HCC in different regions of the world may represent different forms of the disease. METHODS: We compared the patient and tumor characteristics, underlying liver damage, and surgical outcomes of 586 patients who underwent resection of HCC from a multi-institutional database. RESULTS: A total of 169 patients were treated in the United States, 187 in France, and 230 in Japan. The median tumor size for patients treated in the United States was 8 cm, compared with 6 cm and 3.5 cm in France and Japan, respectively (P < 0.001); 20%, 38%, and 74% of patients in the United States, France, and Japan, respectively, had positive hepatitis C serology (P < 0.001). In addition, 65% of patients in Japan had severe fibrosis/cirrhosis in the adjacent liver compared with 52% and 23% of patients in France and the United States, respectively (P < 0.001). There was no association between site of treatment and 30-day (P = 0.4) or 1-year mortality (P = 0.3). The 5-year survival of patients treated in United States, France, and Japan was not statistically different (31% vs. 31% vs. 41%, respectively; P = 0.3). CONCLUSIONS: Although the etiology of HCC and clinicopathologic characteristics of patients treated at western and eastern centers vary widely, postresection 5-year survival is similar when controlling for these factors. Future studies should account for histopathologic differences using uniform criteria to allow better comparison of results.
