OBJECTIVETo summarize the experience with a modeling method for laparoscopic left lateral segment liver resection (LLLR).

METHODSThe surgical procedures of LLLR were carried out with the patient placed in a supine position and 4 trocars placed on the abdomen. After complete dissociation of the left lobe, the segment II and III vascular pedicles were freed with a harmonic scalpel and transected with a linear cutter stapler. The left hepatic vein (LHV) was dissociated with a harmonic scalpel with a slightly left direction of liver dissection, followed by complete resection of the LHV and finally by wound surface management, specimen removal, wound drainage, and abdominal incision closure.

RESULTSBetween July, 2003 and August, 2010, this modeling method for LLLR was performed successfully in 48 cases without conversion to laparotomy. The mean operation time was 75∓30.8 min, blood loss was 58∓36.4 ml, and length of postoperative hospital stay was 4.8∓1.5 days. Postoperative complications occurred in 3 cases, including ascites in 2 cases and mild biliary leakage 1 case, all cured conservatively.

CONCLUSIONThis modeling method can simplify the surgical procedure of LLLR, reduce blood loss, and avoid air embolism due to vein injury. Being less technically demanding, this method can be safely performed in hospitals at various levels.

OBJECTIVETo discuss the value of laparoscopic hepatectomy (LH) for hepatocellular carcinoma (HCC).

METHODSFrom April 2002 to December 2007, 123 cases of HCC, included 82 males and 41 females, with a mean age of 53.8 years (range 31 - 69 years) underwent LH.

RESULTSNinety-three cases underwent total laparoscopic hepatectomies (included regular hepatectomies in 52 cases). Twenty-six cases underwent laparoscopy assisted hepatectomies (included regular hepatectomies in 12 cases). Four cases converted to open hepatectomies because of massive bleeding of hepatic vein. The operative time was (205.5 +/- 92.5) min (range 115 - 290 min). The median intraoperative blood loss was 250 ml (rang 100 - 1500 ml). The postoperative hospital stay was (5.8 +/- 1.6) days (range 3 - 15 days). The biggest size of the resections was 18 cm x 16 cm x 12 cm. One patient died of gas embolism during the operation. Biliary fistula occurred in 5 cases and ascites in 8 cases postoperatively, which were cured for several days. By 4 - 61 months of follow up, recurrence in liver occurred in 5 cases. There was no peritoneum and port metastasis.

CONCLUSIONLH is a safe and feasible method for the treatment of HCC.

OBJECTIVETo summarize the surgical technique and clinical experience of total laparoscopic resection of the pancreatic islet cell tumors.

METHODSFrom July 2002 to December 2007, 30 cases including 12 males and 18 females were diagnosed as pancreatic islet cell tumor. There were at least one positive imaging examination of each patient preoperatively. The location of the tumors included 4 in proximal pancreas and 26 in distal pancreas.

RESULTSThe tumors were successfully found and removed in 28 cases and unsuccessfully located in the other 2 cases. The procedures included local resections in 13 cases and distal pancreatectomies in 15 cases (spleen reserved in 7 cases). The mean operation time was 165 min (range, 65 - 465 min). The mean blood loss was 145 ml (range, 50 - 800 ml). Pancreatic leakage occurred in 3 cases, 2 of which were cured conservatively. And the other one were cured by endoscopic retrograde cannulation of the pancreatic duct. The mean postoperative hospital stay was 5.6 days (range, 2 - 17 d). There were no conversions and death. After follow up of (14.3 +/- 16.7) months (range, 4 - 62 months), there were no recurrences.

CONCLUSIONTotal laparoscopic resection is a safe and effective method for pancreatic islet cell tumors.

Objective To determine the status of false-positive report of congenital syphilis (CS),to analyze the possible causes of mis-diagnosis.Methods Basic information on CS in Shanghai in the past five years was collected.We identified infants diagnosed with CS and followed up the sero- logical reactivity of those patients and their mothers.The serological reactivity[rapid plasmin reagin (RPR)and treponema palidum hemagglutination assay(TPPA)]of infants was followed-up for up to 24 months,or until both antibodies turned to negative.The medical history of the mothers was col- lected,and their sera were examined for syphilitic antibodies.Results Total 99 infants diagnosed with CS were recruited. The major diagnostic method was treponemal antibody detection.Only 31.3% of the 99 infants exhibited clinical symptoms or syphilis-like symptoms at delivery.The cumu- lative RPR loss rates of the infants were 44.2%,64.0%,72.7%,83.9% and 87.1% at 1-3,3-6,6- 12,12-18 and 18-24 months after birth,respectively.The cumulative TPPA loss rates were 1.1%, 18.6%,44.6%,66.7% and 74.4% for 1-3,3-6,6-12,12-18 and 18-24 months after birth,respec- tively.TPPA remained positive in all mothers with syphilis.Conclusion The diagnosis of congenital syphilis determined solely by the positive tests of RPR and TPPA is unreliable and can be misdiagno- sis.The diagnosis and management of congenital syphilis should be urgently improved,and that the profes- sional health institutions should perform and closely monitor the quality controls in the diagnosis of CS and standardize the intervention strategy of maternal syphilis.

OBJECTIVETo compare the clinical results of laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP), confirm the potential advantages of LDP.

METHODSThe medical records of 30 consecutive patients who underwent LDP were reviewed and compared with those of 42 patients who underwent ODP.

RESULTSOperation time was longer for LDP than for ODP [(186.33±58.98 min) vs (149.29±29.00 min), P=0.001], but blood loss [(223.33±143.68 ml) vs(251.19±103.29 ml), P=0.341] and spleen-saving rate(42.3% vs 61.8%, P=0.192) were no significant difference between the 2 groups. Decreased postoperative bowel recovery time [(2.37±0.85 d) vs (2.81±0.67 d), P=0.016], oral intake time [(2.37±0.85 d) vs (2.81±0.67 d), P=0.016] and length of stay [(7.43±1.57 d) vs (9.67±1.41 d), P=0.000] were seen in LDP group. However, the rate of postoperative pancreatic fistula (16.67% vs 21.43%, P=0.619) was no significant difference between the 2 groups. 3 cases of wound infection and 2 cases of lung related complication were occurred in ODP group, but none in LDP group.

CONCLUSIONLDP is a safe and effective surgical approach, providing the same surgical results comparable to that of ODP, and substantially faster recovery. However, high requirement of laparoscopic technique and equipments limited its further clinical application.

OBJECTIVETo explore a new method in estimating extent and degree of arterial injury in upper limbs sustaining high tension electric burns.

METHODSEighteen patients (twenty-four upper limbs) with high tension electricity injury were admitted from December 1998 to September 2002, The damaged limbs consisted of four parts: wrist wound part, 5 cm, 10 cm, 15 cm parts around wrist wound, where the radial and ulnar arteries were detected using B ultrasound and color WP Doppler examination. The changes of endangium, vessel diameter, thickness of the vessel wall and volume of blood flow were recorded respectively. The parameters of normal radial and ulnar arteries were also determined as normal control.

RESULTSB ultrasound and color WP Doppler examination showed that the endangium in radial and ulnar arteries become coarse, edema or exfoliation. The vessel wall was thicker than that of the normal control and the thickness was heterogeneity. The vessel wall could be necrosis in severe patient and the vessel cavity was stricture or beaded. Thrombosis or occlusion could occur at the site of severe injury area in vessel. The decrease in volume of blood flow was observed. The condition of the radial and ulnar arteries become well apart from 10 - 15 cm of wrist wound.

CONCLUSIONSThe ultrasonography can be used to detect the changes in endangium, diameter, thickness of the vessel wall, blood flow volume in injury blood vessel caused by electric burn injury. It is helpful in judging the degree and extent of injury vessel and could be a safe, non-invasive diagnostic method and is worth popularizing.

OBJECTIVETo compare the difference between digital subtraction angiography (DSA) and type B ultrasonography in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.

METHODSNineteen patients with high voltage electrical injury of upper limbs were enrolled in the study as burn group, and another 12 healthy volunteers as controls. The endovascular membrane, vascular wall thickness, intra-vascular blood flow and endovascular thrombosis formation of ulnar and radial arteries at wound site and in regions 5, 10 and 15 cm proximal to the wounds were examined by DSA and type B ultrasonography and compared with imagings of healthy volunteers as control. The injury degree of the ulnar and radial arteries was examined during operation for evaluation to corroborate with DSA and ultrasonography findings. Necrotic and/or thrombotic vessels were excised and sent for pathomorphological examination.

RESULTSBy DSA images abnormal signs as thrombosis, vascular lumen stenosis and blood flow deceleration were found in 14 ulnar and 11 radial arteries, and the signs were more pronounced in ulnar arteries. By type B ultrasonography, abnormal signs as roughing of tunica intima, swelling or exfoliation, thickening of vascular wall, lumen stenosis, decreased blood flow, even necrosis of vascular wall and thrombosis were identified in 19 ulnar and 16 radial arteries in burn group (P < 0.05 approximately 0.01). The blood flow in ulnar artery 5 cm to the approximal part of the wound edge was obvious lower than that of the control (31.60 +/- 13.90 ml/min vs 47.70 +/- 9.60 ml/min, P < 0.05).

CONCLUSIONType B ultrasonography and DSA could be helpful in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.
