[Usefulness of an Epidural Catheter with a Subcutaneous Port for Locally Advanced Rectal Cancer Pain Which Was Difficult to Manage with Opioids-A Case Report].

A 56-year-old woman was diagnosed with advanced rectal cancer, with tumor invasion to the sacrum and levator muscle of the anus and multiple lymph node metastasis. After construction of an artificial anus, chemotherapy was started. However, tumor invasion and the cancer pain progressed. Finally, she was hospitalized for pain control; an anesthesiologist planned to insert an epidural catheter. The epidural catheter was placed at the L5-S1 interspace, and continuous administration of 0.2% ropivacaine was started. Cancer pain in the buttocks improved quickly. Therefore, an epidural catheter with a subcutaneous port was placed to prevent catheter-related infection after a long period. The postoperative course was uneventful, and she was discharged from the hospital on the 10th day postoperatively. She could receive home medical care and pain control treatment in an outpatient clinic. Finally, she died due to progression of the rectal cancer, 3 months after placement of the epidural catheter with the subcutaneous port. Some patients with advanced rectal cancer develop cancer pain even though they are sufficiently treated with opioids or palliative radiation therapy. Here, we describe the case of a patient with locally advanced rectal cancer, treated with an epidural catheter with a subcutaneous port for cancer pain that was difficult to manage with opioids alone.

Securing the surgical field in laparoscopic pancreatectomy using a Penrose drain and Endo Close.

INTRODUCTION: We adopted the use of Penrose drains and Endo Close to secure a good surgical field during laparoscopic pancreatectomy. METHODS: We used a Penrose drain with threads ligated on both ends to suspend the stomach. We then pulled the threads out of the body from the side of the trocar or from besides the xiphisternum by using Endo Close. In most cases, 2 Penrose drains were used to retract the stomach. When the greater omentum on the left side of the cardia still blocks the surgical field, we sewed the posterior wall of the stomach onto the dome of the diaphragm. RESULTS: The use of 2 Penrose drains and Endo Close were effective to retract the stomach in most cases. However, in 3 cases, we needed to additionally sew the stomach onto the diaphragm to fully open up the field. CONCLUSION: This is a simple and effective method to ensure a good surgical field.

Laparoscopic resection of a paraganglioma located on the border of the thoracic and abdominal cavities using a transabdominal-transdiaphragmatic approach.

We treated a 64-year-old woman with high blood pressure. Catecholamine metabolite levels were elevated in the blood and urine. CT revealed a densely stained tumor on the right side of the descending aorta dorsal to the inferior vena cava. PET-CT revealed abnormal accumulation of (18) F-fluorodeoxyglucose, and (123) I-meta-iodo-benzylguanidine uptake was apparent on scintigraphy. The tumor was determined to be a paraganglioma located on the border between the thoracic and abdominal cavities, and laparoscopic tumorectomy was performed. The patient was placed in the left lateral position. The right lobe of the liver was turned over, and we cut the diaphragm to expose the front of the tumor. We resected the straight artery flowing in from the aorta and removed the tumor safely. Herein, we describe the removal of a paravertebral paraganglioma located in the border of the thoracic and abdominal cavities with a laparoscopic transabdominal-transdiaphragmatic approach.

[A case of advanced pancreas cancer successfully treated by using combined modality therapy].

A 62-year-old woman visited a nearby hospital with chief complaints of diarrhea and weight loss.A computed tomography (CT)scan showed a hypovascular tumor approximately 2 cm in diameter in the pancreatic uncus, and the patient was referred to our department for thorough examination and treatment.The patient was diagnosed with cT4 (A) N0M0, cStage IV a cancer of the pancreatic uncus.The treatment consisted of 3 weeks of gemcitabine and 1 week of drug withdrawal; after completion of 4 courses, concomitant administration of S-1 (ie GS therapy) was initiated.The tumor gradually shrank, and it was not observed on a CT scan 1 year and 8 months later.Although no obvious distant metastasis was observed, a low density area around the superior mesenteric artery still remained.Possibility of viable tumor could not be completely ruled out; therefore, a pancreaticoduodenectomy was scheduled.However, because sclerosis around the superior mesenteric artery was quite severe, bled easily, and was difficult to separate, we decided that excision was impossible and resumed the GS therapy. The primary lung cancer that developed subsequently was resected, and the GS therapy was continued.The tumor in the pancreatic uncus was resected after growth was observed 3 years and 9 months after the initiation of chemotherapy.The patient is currently receiving chemotherapy as an outpatient.

[A case of long-term survival after peritoneal recurrence of rectal cancer achieved by tumorectomy and adjuvant chemotherapy].

The patient was a 40-year-old woman.She began experiencing abdominal pain and constipation in July 2005.S he underwent endoscopy in August, which revealed rectal cancer.She was referred to our hospital for surgery and underwent anterior resection with lymph node dissection in September. The pathological diagnosis was tub2, SS, N2, ly1, v1, stage III b. After discharge, she began oral chemotherapy. However, in April 2006, computed tomography (CT) revealed recurrence in the Douglas pouch. She began FOLFOX4 treatment in May.On follow-up CT performed in July, the recurrent sites were limited to 2 nodules and were deemed resectable. The patient underwent peritoneal dissemination resection, and the pathological diagnosis was metastatic tumor.She subsequently received 11 postoperative FOLFOX4 courses. The chemotherapy regimen was changed to the de Gramont regimen because of peripheral neuropathy. After 56 courses of the de Gramont regimen, the chemotherapy regimen was further changed to UFT/UZEL. The patient received 28 additional courses but experienced hair loss and requested treatment cessation. To date, she remains alive without recurrence.

Modified Pringle Maneuver Applicable for Laparoscopic Hepatectomy.

INTRODUCTION: We present a widely applicable technique of the modified Pringle maneuver to reduce blood loss for laparoscopic hepatectomy. METHODS: We use a drip-infusion tube and wrap it around the hepatoduodenal ligament. In the modified Pringle maneuver ① (m-Pringle ①), we use a 60 cm long tube. Both ends of the tube are led out from the side of the umbilical port, then pulled and clipped with Pean forceps to interrupt blood flow. In the modified Pringle maneuver ② (m-Pringle ②), we use a 20 cm long tube with silk threads tied at both ends. The threads were led extraperitoneally in the same manner. RESULTS: Although blood flow was sufficiently interrupted, CO2 leak occurred in 14 of 60 cases in m-Pringle ①. Blood flow was interrupted and intra-abdominal pressure was kept in all 10 patients in m-Pringle ②. CONCLUSIONS: These maneuvers require no extra port, and tube pulling and releasing is readily performed from outside the body.

[Retrospective analysis of the bevacizumab and CapeOX combination in untreated metastatic/recurrent colorectal cancer].

In recent years, there has been significant progress in systemic chemotherapy for metastatic or recurrent colorectal cancer. We investigated the clinical efficacy and feasibility of the bevacizumab and capecitabine /oxaliplatin(CapeOX)combination for untreated colorectal cancer. From October 2009 to June 2012, 38 patients were included, 18 receiving CapeOX alone and 20 receiving CapeOX plus bevacizumab. The response rate and disease-control rate were 16% and 5 0%, respectively, in the CapeOX arm, and 5 5% and 8 5%, respectively, in the CapeOX plus bevacizumab arm. Median progression-free survival was 8.0 months in the CapeOX arm and 1 2.8 months in CapeOX plus bevacizumab arm. The median overall survival was 21.6 months in the CapeOX arm and 3 4.0 months in CapeOX plus bevacizumab arm. Our results suggest that CapeOX treatment can be useful in the outpatient setting and more effective when combined with bevacizumab. Except in cases of bevacizumab intolerance, addition of bevacizumab to CapeOX treatment is considered useful as first-line therapy for metastatic or recur- rent colorectal cancer.

Three-dimensional computed tomography for analyzing the vascular anatomy in laparoscopic surgery for right-sided colon cancer.

BACKGROUND: The mesenteric vessels have many branching patterns. This study clarified the anatomic relationship between the superior mesenteric vein (SMV), the right colic artery (RCA), and the ileocolic artery (ICA) using 3-dimensional computed tomography (3D-CT). The relationship between the RCA and the right colic vein (RCV) was also examined. METHODS: Between April 2006 and July 2011, all patients with colorectal cancer underwent multidetector computed tomography (MDCT) before laparoscopic surgery. The 100 most recent consecutive cases were analyzed. 3D-CT images were made by combining arterial angiography, venous angiography, colonography, tumor, lymph node, and duodenal images. RESULTS: The RCA branched from the SMA in 37 cases (37%); of these, 21 had an ICA that crossed anterior to the SMV and 16 had an ICA that crossed posterior. When the ICA crossed anterior to the SMV, all had an RCA that crossed anterior to the SMV, and no posterior RCA was seen. Furthermore, the RCV joined the SMV in 10 cases (27%) and the gastrocolic trunk in 27 cases (73%). CONCLUSIONS: Our study clarified the anatomic variety of the vessels in right-sided colon cancer. Preoperative 3D-CT is useful for understanding the anatomy to ensure a safe, precise operation.

[Pathological complete remission using low-dose cisplatin plus S-1 for gastric cancer patient with liver metastases].

A 70-year-old female presented with epigastralgia. Gastrointestinal endoscopic examination showed advanced gastric cancer type 2. Computed tomography(CT)showed a liver tumor of 37mm in segment 6. She was treated with oral S-1, 80 mg/body for 14 days, followed by a 7-day rest, and CDDP 20mg/m2(day 1 and 8). After ten courses of treatment, CT showed reduction of the primary cancer, the liver tumor, and the affected lymph nodes. Then, distal gastrectomy, lymph node dissection, and partial liver resection were performed. The histological diagnosis was no viable cancer cells found in stomach, liver or lymph nodes. One year and 1 month postoperatively, the patient is alive without recurrence.

Effect of flurbiprofen, metoclopramide and droperidol for nausea and emesis during cesarean section under spinal anesthesia.

PURPOSE: Nausea and emesis frequently arise during cesarean section performed under spinal or epidural anesthesia, particularly after delivery. We have evaluated the treatment effects of flurbiprofen, metoclopramide and droperidol on nausea and emesis during cesarean section in patients under combined spinal and epidural anesthesia. METHODS: The patient cohort comprised 361 patients with American Society of Anesthesiologists (ASA) physical status I or II who elected to undergo cesarean section. All patients received combined spinal-epidural anesthesia. After delivery, nausea and emesis was assessed using a 4-point scale as: 1, excellent, with no complaints; 2, mild nausea; 3, severe nausea; 4, emesis. Patients who experienced severe nausea or emesis were randomly assigned to receive one of the following intravenous drugs: Group A, flurbiprofen (50 mg); Group B, metoclopramide (10 mg); Group C, droperidol (1.25 mg). Effects on nausea and emesis were assessed at 5, 10 and 15 min after drug administration using a 4-point scale as: 1, obviously improved; 2, improved; 3, unchanged; 4 worsened. RESULTS: Among the patients, 151 reported nausea or emesis. These patients experienced a longer duration of surgery and anesthesia and lost more blood than patients with no complaints. The frequency of improvement in the flurbiprofen group was significantly higher than that in the metoclopramide group at 5, 10 and 15 min (p < 0.05) after administration, and of that in the droperidol group at 15 min after administration (p < 0.05). CONCLUSION: Intravenous flurbiprofen improves nausea and emesis after delivery by cesarean section more effectively than metoclopramide or droperidol.

The effects of volatile anesthetics on nonadrenergic, noncholinergic depressor responses in rats.

UNLABELLED: The effects of volatile anesthetics on nonadrenergic, noncholinergic (NANC) transmission mediated by calcitonin gene-related peptide (CGRP) are unclear. We studied the effects of isoflurane, halothane, and sevoflurane on NANC depressor responses to electrical spinal cord stimulation in pithed rats whose mean arterial blood pressure was maintained near 120 mm Hg by continuous infusion of methoxamine. Autonomic outflow was blocked by hexamethonium. After 30 min of inhalation of different concentrations of anesthetics, spinal cord stimulation at the lower thoracic level (10 V at 4 Hz; duration, 1 ms) was applied for 30 s to induce a NANC depressor response. Isoflurane at 2% and halothane at 1.5% attenuated NANC depressor responses significantly, whereas isoflurane at 1%, halothane at 0.75%, and sevoflurane at 2% or 4% did not. Volatile anesthetics did not attenuate the release of CGRP after spinal cord stimulation, whereas isoflurane at 2% and halothane at 1.5% significantly inhibited depressor responses to exogenously administered CGRP. Sevoflurane at 4% did not significantly affect CGRP-induced depressor responses. Thus, isoflurane and halothane at large concentrations attenuate NANC depressor responses by attenuating the depressor action of CGRP, not CGRP release. IMPLICATIONS: The anesthetics isoflurane and halothane attenuate nonadrenergic, noncholinergic depressor responses mediated by calcitonin gene-related peptide in the rat without affecting the release of the peptide.
