RESUMEN
BACKGROUND: Indocyanine green fluorescence imaging (ICG-FI) has been reported to be useful in reducing the incidence of anastomotic leakage (AL) in colectomy. This study aimed to investigate the correlation between the required time for ICG fluorescence emission and AL in left-sided colon and rectal cancer surgery using the double-stapling technique (DST) anastomosis. METHODS: This retrospective study included 217 patients with colorectal cancer who underwent left-sided colon and rectal surgery using ICG-FI-based perfusion assessment at our department between November 2018 and July 2022. We recorded the time required to achieve maximum fluorescence emission after ICG systemic injection and assessed its correlation with the occurrence of AL. RESULTS: Among 217 patients, AL occurred in 21 patients (9.7%). The median time from ICG administration to maximum fluorescence emission was 32 s (range 25-58 s) in the AL group and 28 s (range 10-45 s) in the non-AL group (p < 0.001). The cut-off value for the presence of AL obtained from the ROC curve was 31 s. In 58 patients with a required time for ICG fluorescence of 31 s or longer, the following risk factors for AL were identified: low preoperative albumin [3.4 mg/dl (range 2.6-4.4) vs. 3.9 mg/dl (range 2.6-4.9), p = 0.016], absence of preoperative mechanical bowel preparation (53.8% vs. 91.1%, p = 0.005), obstructive tumor (61.5% vs. 17.8%, p = 0.004), and larger tumor diameter [65 mm (range 40-90) vs. 35 mm (range 4.0-100), p < 0.001]. CONCLUSION: The time required for ICG fluorescence emission was associated with AL.

A 66-year-old man was referred to our department with the diagnosis of ascending colon cancer. He was undergoing dialysis for chronic renal failure due to diabetic nephropathy. Laparoscopic ileocecal resection was planned for the ascending colon cancer, but the procedure was converted to laparotomy owing to intraoperative bleeding. The patient was discharged from the hospital after 7 days. On the 14th postoperative day, the patient presented with purulent drainage from the wound and fever and was diagnosed to have a minor anastomotic leak. The suture of the anterior sheath was exposed in part of the wound. The patient's general condition was stable, and conservative treatment was planned. However, when he coughed, the wound separated and the intestine prolapsed, and emergency surgery was performed. Intraoperative findings showed leakage of intestinal fluid from the anastomotic border, and we diagnosed delayed suture failure. We present a rare case of delayed anastomotic leakage in a hemodialysis patient.

A 78-year-old male presented with a positive fecal occult blood test. Rectal cancer was detected during lower gastrointestinal endoscopy, and further investigations led to a diagnosis of cT1N0M0 cStage I (UICC classification, 8th edition). Preoperative contrast-enhanced computed tomography (CT) showed that the patient also had Leriche syndrome, which is associated with reduced blood flow to the rectum that may result in ischemic anastomosis during rectal cancer surgery with anastomotic reconstruction. The inferior epigastric arteries often function as collateral pathways to the lower limbs in patients with Leriche syndrome; therefore, care is needed to avoid vascular damage during trocar insertion when performing laparoscopic surgeries. We herein described a case of safe laparoscopic low anterior resection in a rectal cancer patient with Leriche syndrome using vascular architecture images obtained by preoperative CT angiography.
RESUMEN
BACKGROUND: Recently, the hospital information systems (HIS) and anesthesia information management systems (AIMS) have been rapidly improved and have been introduced into the clinical practice in Japan drastically; however, few reports have detailed their influences on clinical practice. We here report our experience. METHODS: We introduced HIS (EGMAIN-EX, Fujitsu Co., Ltd.) in our preoperative evaluation clinic and in the postoperative care unit. AIMS (ORSYS, Philips Electronics Japan) was introduced almost only to the intraoperative management. RESULTS: It became easy for us to acquire patient's information and to share it with the medical staffs in the other departments. However, we had to invest large human resources for the introduction and maintenance of the HIS and the AIMS. CONCLUSIONS: Though AIMS is more useful in anesthetic management than HIS, it seems to be more suitable for coordination with the medical staffs in the other departments to use HIS for perioperative management than to use AIMS.

A 74-year-old woman was scheduled for a hepatectomy. Delayed emergence from anesthesia was anticipated because she had renal failure and liver dysfunction. We induced and maintained anesthesia for 478 minutes with propofol and remifentanil. The intraoperative course was uneventful and emergence from anesthesia was not delayed. Spontaneous respiration returned and her trachea was extubated 15 minutes after the surgery. Postoperative analgesia was established by epidural ropivacaine. This case shows that remifentanil is effective in anesthetic management for a patient with renal failure and liver dysfunction undergoing hepatectomy due to its unique mode of metabolism.

We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux-en-Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.

In this study, we administered various diets of stearidonic acid (SDA, 18:4n-3) soybean oil to rats and examined the subsequent blood and organ biochemical parameters. Male Wistar rats (seven rats/group, six groups total) were fed diets supplemented with a test oil for 4 weeks. Diets containing test oils were: FFC diet (fish-oil-free control diet), C diet (control group, assuming a Japanese diet), SDA25 diet (25% 18:4n-3 soybean oil in the C diet), SDA50 (50% 18:4n-3 soybean oil in the C diet), ALA diet (34% flaxseed oil in the C diet), and EPA+DHA diet (34% fish oil in the C diet). The intake of 18:4n-3 showed increased relative efficiency of 20:5n-3 accretions in serum and liver triacylglycerol and significantly decreased the serum triacylglycerol level in rats. The results suggested that the consumption of 18:4n-3 soybean oil may modify the lipid and fatty acid profiles of body fats, even when EPA and DHA derived from fish is consumed.

We studied the relationship between dietary intake and the blood compositions of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid (ARA) in four study groups with different ages and sexes. One hundred and four subjects were recruited. Dietary records together with photographic records from 28 consecutive days were amassed and the fatty acid composition in erythrocyte membranes and plasma lipid fractions was analyzed. Fish intake in the elderly group was significantly higher than that in the young group in both men and women. The compositions of ARA in erythrocytes and plasma phospholipids in the elderly were lower than those in the young, but the ARA intake was nearly identical. In the elderly group, the percentage of dietary ARA consumed at the same time as EPA and DHA derived from fish was high. We considered that these fatty acids markedly inhibited the incorporation of dietary ARA into blood phospholipids.

OBJECTIVES: Previous data have indicated that the erythrocyte membrane may be the preferred sample type for assessing long-chain polyunsaturated fatty acid (LCPUFA) contents in cardiac and cerebral membranes. In this epidemiological study, we examined whether plasma phospholipids can be used for accurate biological monitoring of the LCPUFA state or whether analysis of erythrocyte membrane phospholipids is indispensable. METHODS: (1) The analysis of LCPUFA contents in erythrocyte membrane phospholipids was conducted at baseline and after 1 and 3 days at 4°C, and 21 days at -40°C, after blood drawing, and the changes in LCPUFA content were examined. (2) The LCPUFA compositions of plasma and erythrocyte phospholipids in 133 young women (18-30 years old) were examined and the relationships between the sample type and the levels of LCPUFAs were determined. RESULTS: Eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and DHA/arachidonic acid (AA) and (EPA+DHA)/AA ratios in erythrocyte membrane phospholipids after 21 days of blood drawing significantly decreased compared with the corresponding baseline data. Regarding AA, EPA and DHA, a significant positive correlation was shown between levels of erythrocyte membrane phospholipids and plasma phospholipids (AA, r=0.364; EPA, r=0.709; DHA, r=0.653). The predictive value of plasma phospholipids for determining the highest concentration quartile in erythrocyte phospholipids was better in EPA (70%) than in DHA (55%) and AA (42%). CONCLUSIONS: The measurement of LCPUFA content in erythrocyte membrane phospholipids is necessary for accurate biological monitoring. We also found that LCPUFA in erythrocyte membrane phospholipids is stable in cold storage (4°C) for 3 days after blood drawing.

Because trans fatty acids (TFAs) are a potent risk factor for coronary heart disease, it is important to know the amount of TFA consumed. We estimated TFA intakes of Japanese university students by direct measurement. Subjects included 118 students (57 males and 61 females) in two regions of Japan: Kanto (Tokyo area) and Okinawa. A dietary survey was conducted over six consecutive days using dietary records and photographic records. A single-day meal in the survey period was reproduced to measure TFA content by gas chromatography. The median values of TFA intakes (and energy percentage) estimated by the contents of reproduced meals for men were 0.43 g/d (0.22%) in Kanto and 0.30 g/d (0.14%) in Okinawa. Corresponding values for women were 0.49 g/d (0.29%) and 0.73 g/d (0.35%), respectively. Compared to the group with a low TFA intake, the subjects with a high TFA intake consumed significantly more energy from total fat and saturated fatty acids, and had a high ratio of TFA/linoleic acid. In addition, multiple regression analysis showed the intakes of TFA were positively associated with those of saturated fatty acids and groups of nonessential groceries such as cookies, cakes and pastries. In conclusion, the TFA intakes of these survey subjects were relatively lower than the WHO recommended energy ratio (<1%). However, nutritional education on dietary habits seems indispensable for those subjects who are consuming high volumes of TFA.
