RESUMO
BACKGROUND/AIMS: To compare the postoperative results of duodenum-preserving pancreatic head resection (DPPHR) techniques with those of conventional pancreatoduodenectomy (PD). METHODOLOGY: We retrospectively reviewed the records of 58 patients who underwent DPPHR or PD at Jinhua central hospital between May 1998 and May 2011. RESULTS: Eighteen patients underwent DPPHR (Group 1) and 40 conventional PD (Group 2). They were followed up for more than 6 months. Operation time in Group 1 was longer (290±18 min vs 269±14 min, p=0.001). Estimated blood loss in Group 1 was more (633±88 mL vs. 495±131 mL, p=0.003). Intraoperative transfusion in Group 1 was more (533±88 mL vs. 335±218 mL, p=0,001). However, postoperative transfusion was Iess (141±162 mL vs. 440±193 mL, p=0.000). Group 1 had a lower short-term complication rate (16.67% vs. 50.0%, p=0.0 16) and long-term complication rate (11.11% vs. 45.0%, p=0.012). Hospital mortality of both groups were 0. CONCLUSIONS: DPPHR for benign or premalignant lesions is a difficult procedure, but with a lower complication rate than conventional PD. Preserving the entire duodenum and a normal biliary tree allows better short-term and long-term results. DPPHR will be suitable for only a small group of patients and should be performed by experienced surgeons.

This report presents the case of a 51-year-old man who had an axillary arteriovenous fistula (AVF) as a complication of an axillary plexus block that was performed for internal fixation for a right forefinger phalanx fracture 4 years previously. While performing the axillary plexus block, a 22-gauge needle was placed inside the axillary sheath by observing the pulsations of the axillary artery. A pulsatile mass was found in the right axilla 1 day after the block was performed. Apart from this soft mass, the patient had no symptoms of vascular nerve damage. As the mass gradually increased in size, it became painful. During the past 3 months, in particular, the patient experienced repeated attacks of intermittent sharp pain and requested surgery. Digital subtraction angiography, performed 4 years after the axillary block, showed a tumor-like dilation was developing in both the right axillary artery and vein, almost simultaneously. Thus, the diagnosis of AVF was confirmed. The false aneurysm sac was excised and lateral repair of the axillary artery and vein was carried out under general anesthesia. Postoperative recovery was uneventful. The possible occurrence of an AVF after axillary plexus block should be kept in mind, because early diagnosis and treatment are necessary to avoid development of AVF and false aneurysm.

White cord syndrome refers to an emerging neurological dysfunction occurring after spinal decompression surgery with hyperenhancing changes on T2-weighted magnetic resonance imaging (T2WI). The pathophysiological mechanism is hypothesized to be an ischemia-reperfusion injury following chronic ischemic spinal cord decompression. A 54-year-old man was admitted to Jinhua Municipal Central Hospital with complaints of numbness and weakness in the extremities and swelling in the neck. MRI showed degeneration and herniation of the C4-C7 intervertebral discs. The patient underwent anterior cervical corpectomy and fusion (ACCF). On the 7th postoperative day, the patient reappeared with weakness of the limbs. Physical examination revealed paralysis. Emergency MRI suggested T2 high signal myelopathy and emergency surgery was performed following the diagnosis of white cord syndrome. Following the operation, the patient's neurological system gradually improved. The motor ability and sensory function of the extremities recovered at 7-month follow-up. Spine surgeons should be aware of this serious complication. The present case serves to provide experience for clinical treatment and diagnosis and encourage research into its pathophysiology.
RESUMO
AIM: To study the risk factors for morbidity and mortality following total gastrectomy. METHODS: We retrospectively reviewed the records of 125 consecutive patients who underwent total gastrectomy for gastric cancer at the Second Affiliated Hospital of Zhejiang University School of Medicine between January 2003 and March 2008. RESULTS: The overall morbidity rate was 20.8% (27 patients) and the mortality rate was 3.2% (4 patients). Morbidity rates were higher in patients aged over 60 [odds ratio (OR) 4.23 (95% confidence interval (CI) 1.09 to 12.05)], with preoperative comorbidity [with vs without, OR 1.25 (95% CI 1.13 to 8.12)], when the combined resection was performed [combined resection vs total gastrectomy only, OR 2.67 (95% CI 1.58 to 5.06)]. CONCLUSION: Age, preoperative comorbidity and combined resection were independently associated with the rate of morbidity after total gastrectomy for gastric cancer.

To study a more micro-invasive procedure for patients having pancreatic duct stones (PDS). Till now, there has been no report of laparoscopic pancreatic duct incision and stone removal and T-type tube drainage for PDS in the English literature. An 82-year-old man suffered from subxiphoid pain associated with a dilated pancreatic duct (7 mm) containing one stone, but without a mass in the head of the pancreas. Laparoscopic pancreatic duct incision, stone removal, and T-type tube drainage were successfully performed without intraoperative or postoperative complications. An uneventful operation was performed with laparoscopically completed procedures in 160 min. The intraoperative loss of blood was around 50 mL. After patient a discharge on day 11, complete relief from the subxiphoid pain was reported at a follow-up visit 15 mo later. Laparoscopic pancreatic duct incision with stone removal and T-type tube drainage is applicable in carefully selected patients and can be effectively and safely used for the treatment of the abdominal pain of chronic pancreatitis.
RESUMO
BACKGROUND: Pancreatic carcinoma possesses one of the highest lethality rates, highest drug-resistance, and highest incidence rates. The objective of this research was to enhance the efficacy and drug-resistance for pancreatic carcinoma by using inhibition of SIRT1 combined with gemcitabine therapy methods. METHODS: Three pancreatic carcinoma cells (PANC-1 cells, BxPC-3 cells, and SW1990 cells) received treatment with physiological saline, inhibition of SIRT1, gemcitabine, and combination therapy with inhibition of SIRT1 and gemcitabine in vitro; then BxPC-3 pancreatic cancer xenogeneic mice also received treatment with physiological saline, inhibition of SIRT1, gemcitabine, and combination therapy with inhibition of SIRT1 and gemcitabine in vivo. RESULTS: The cleaved poly ADP ribose polymerase (PARP)-1 effect of drug in pancreatic carcinoma cells was significantly different (P < 0.05) and the efficacy in descending order was the combination therapy with inhibition of SIRT1 and gemcitabine, inhibition of SIRT1, and gemcitabine. The BxPC-3 pancreatic cancer xenogeneic mice model received treatment with physiological saline, inhibition of SIRT1, gemcitabine, and combination therapy with inhibition of SIRT1 and gemcitabine in vivo and the results showed that the tumor volumes decreased and the survival rate within 45 days increased according to the order of the given drugs and the difference was significant (P < 0.05). CONCLUSION: Combination therapy with inhibition of SIRT1 and gemcitabine could improve efficacy and survival time in a BxPC-3 pancreatic cancer xenogeneic mice model, compared with single inhibition of SIRT1, or single gemcitabine therapy. The combination therapy method is a potential treatment method for pancreatic carcinoma.
