In a prospective study, patients undergoing abdominal cancer surgery were randomly allocated to receive either general anesthesia with fentanyl intravenously and postoperative analgesia with parenteral morphine (GA group) or general anesthesia combined with epidural bupivacaine and epidural morphine for postoperative pain relief (EP group). Analgesia was tested on a visual pain scale. Pulmonary complications were evaluated by clinical complications, blood gas analysis, x-ray film changes, and pulmonary volumes (vital capacity, forced expiratory volume in 1 second). Measurements were performed on the day before the operation and on the first 5 postoperative days. In the EP group the pain relief was significantly better on the first day (p less than 0.03). Whatever the criteria used, the rates of pulmonary complications were similar in the two groups: clinical complications 21% versus 26%, radiologic complications 50% versus 64% for GA and EP groups, respectively. Postoperative PaO2 and spirometric values were similar in the two groups. Postoperative epidural analgesia may improve the patient's comfort but does not decrease the incidence of pulmonary complications.

Epidural opiate application was performed in 75 patients with chronic pain due to abdominal cancer. To reduce the risk of local infection, the epidural catheter was in part placed subcutaneously. Degree and duration of analgesia were determined after epidural morphine (with and without bupivacaine), pethidine or fentanyl. Hemodynamic and respiratory parameters were measured and side-effects were registered. The longest duration of analgesia was observed after epidural morphine. In long-term treatment there was a reduced efficiency and the frequency of daily injections increased, especially in those patients who already had received systemic opiates prior to the epidural opiate administration. This may be due to tolerance of the spinal receptors. A combination of epidural morphine with small doses of local anesthetics caused prolonged action and delayed the onset of tolerance. Besides slight influences on respiratory function, which may be referred to the initial period of systemic absorption, there were no relevant side-effects. Regarding certain precautions the epidural application of morphine may have advantages in comparison to systemic analgetics in treatment of chronic pain.

To verify the effectiveness and the incidence of complication in the transcutaneal celiac plexus block with CT-guided in the patient with intractable upper abdominal cancer, using alcoholic solutions to different concentrations (50% and 96%), previous insertion of the peridural catheter. From December 1997 to June 2002, studies were carried out on 24 patients with CT-guided percutaneous coeliac plexus neurolysis including 17 men and 7 women with inoperable abdominal malignancy and two with chronic pancreatitis. The patients were affected by very intense pain controllable only with high doses of analgesic narcotics. Before the procedure a catheter was installed in the peridurale space between L1-T12. To avoid general anesthesia, 40 mL of marcaine 0.5% was injected to relieve the back pain sometimes reported after the neurolysis, caused by the diffusion of alcohol in the coeliac plexus. This technique requires a posterior percutaneous procedural transaortic approach CT scan guided, to determine the correct position of the needle tips and the spread of neurolytic solution (40 mL of 96% + 3 mL of contrast medium) around the origin of the coeliac trunk's anatomical center of the plexus. The first 10 patients have received 40 mL of 50% ethyl alcohol + 3 mL of contrast medium. To evaluate the rate of the analgesia relief, a visual analogue pain score (VAS) was used before and 48 hours after the neurolysis. The percutaneous neurolysis of the celiac plexus is useful to relieve the pain in patients affected by cancer developing in upper abdomen. The CT-scan guide of the needle allows an omogeneous distribution of the contrast medium. The insertion of the peridural catheter made a complete analgesia and reduced the incidence of complications. Our method provided an excellent control of the pain in all patients. In our experience the pain relief was almost complete in patients treated with 96% ethyl alcohol solution (VAS from 8 before the treatment to 1, 48 hours after the treatment). The alcohol administered in elevated concentrations (96%), does not increase the incidence of complications.

The study was undertaken to evaluate the effectiveness and safety of ropivacaine used via long-term epidural infusion and to define the optimum doses of the agent in the intra- and postoperative period. The parameters of hemodynamics, the adequacy of anesthesia, and the consumption of the agent were explored in 53 patients (ASA III-IV) aged 68 +/- 1.4 years operated on for abdominal cancer. Following 15 and 25 min of the injection of a bolus dose of ropivacaine, the occurrence of sensory block II was observed in 60 and 95% of the patients, respectively. After injection of ropivacaine in a bolus dose (56 +/- 3.4 mg), there was a 20% lowering of mean blood pressure and a 17% reduction in heart rate as compared with the baseline values. Maintenance infusion was made at a rate of 15-25 (20 +/- 1.9) mg/h. The total consumption was 126 +/- 13 mg. Bradycardia was noted in 4 (7.5%) cases; 7 (13%) patients required additional administration of phentanyl. The latter was used in a dose of 100 microg in 87% of the patients only prior to tracheal intubation. For postoperative analgesia, 0.2% ropivacaine was infused at a rate of 6-10 ml/h. Increasing its dose up to 12-14 ml/h resulted in hypotension and the occurrence of the signs of motor block. Postoperative analgesia was effective in 89% of cases when the agent was infused at rate of 8.8 +/- 0.9 ml/h and the hemodynamic parameters were stable. Postoperative intestinal paresis was abolished in 85.8% of patients after an average of 52 +/- 2.7 hours. Long-term epidural infusion of ropivacaine may be regarded as an effective component of anesthesia at abdominal surgery in elderly patients with severe comorbidity. The method allows one to completely refuse the use of narcotic analgesics in most cases both during a surgical intervention and in the postoperative period, which creates good conditions for an early activation of patients and for a reduction of postoperative complications.

This case report series describes eight patients (four patients with pancreatic carcinoma, one patient with hepatocellular carcinoma, one patient with gastric and rectal carcinoma, one with sigmoid colon cancer, and one with rectal cancer), whose abdominal cancer pain was treated with intravenous phentolamine infusion at 80 mg x day(-1) for 2 days. All but one of the patients had already been treated with opioids. All eight patients complained of severe abdominal pain; in five patients the pain radiated to the back, and there was associated anal pain in two patients. Analgesia was achieved in three patients; pain alleviation was obtained in four patients, but was not sustained in two of these four patients; and the treatment in one patient could not be judged for efficacy because epidural morphine was used together with the phentolamine. Adverse effects of phentolamine were tachycardia and/or hypotension.

Interpleural blockade is effective in treating unilateral surgical and nonsurgical pain from the chest and upper abdomen in both the acute and chronic settings. It has been shown to provide safe, high-quality analgesia after cholecystectomy, thoracotomy, renal and breast surgery, and for certain invasive radiological procedures of the renal and hepatobiliary systems. It has also been used successfully in the treatment of pain from multiple rib fractures, herpes zoster, complex regional pain syndromes, thoracic and abdominal cancer, and pancreatitis. The technique is simple to learn and has both few contra-indications and a low incidence of complications. In the first of two reviews, the authors cover the history, taxonomy and anatomical considerations, the spread of local anaesthetic, and the mechanism of action, physiological, pharmacological and technical considerations in the performance of the block.

In a randomized, controlled study, 50 patients underwent elective surgery for abdominal cancer lesions under perioperative epidural analgesia. All the patients were randomized to receive paracetamol in a single intravenous dose of 1 g or placebo 30 minutes prior to the start of surgery. The use of 1 g of paracetamol as a single intravenous preemptive dose in abdominal surgery with perioperative epidural analgesia does not reduce the consumption of the analgesic and the intensity of pain in the postoperative period.

Pain is commonly perceived by patients during cancer and its treatment. Although most patients respond to conservative management implemented according to the World Health Organization guidelines, a subset of patients with advanced disease develop intractable pain that may require additional interventions such as regional blocks and intrathecal therapy. Patients with terminal abdominal or pelvic cancer who have high tumor burdens are often offered a diagnostic visceral nerve block followed by neurolysis for pain palliation. Conventional visceral blocks usually require fluoroscopic guidance for correct needle placement in the vicinity of the neuroaxis or abdominal cavity. These techniques carry risks of injury to vessels, bowels, and nerves. Transversus abdominis plane (TAP) block is a technique that is easy to perform (particularly when ultrasonographic guidance is used), has a good safety record, and effectively reduces pain levels and opioid requirements after abdominal and gynecological surgery. Although numerous studies have demonstrated the effectiveness of TAP blocks in acute pain management, the role of TAP block in chronic pain management is very limited. We believe that chemical neurolysis with phenol can prolong the effects of analgesia in patients with terminal cancer. We describe a case of terminal abdominal sarcoma with intractable pain that responded well to a TAP block followed by TAP neurolysis. The patient tolerated the procedure well and demonstrated sustained analgesia for 45 days before dying of the disease. We also demonstrated that TAP block significantly reduces the total opioid requirement as demonstrated by the morphine equivalent daily dose score after the neurolytic procedure. This result supports our belief that TAP block with TAP neurolysis is an effective and inexpensive modality that can be used to palliate intractable abdominal wall pain in patients with terminal abdominal cancer.

A 35-year-old man stopped breathing after injecting a large dose of heroin. He subsequently received cardiopulmonary resuscitation from friends. He arrived to accident and emergency department with Glasgow Coma Scale of 13. On examination, he had distended and tense abdomen. CT Thorax, Abdomen, and Pelvis confirmed massive tension pneumoperitoneum. A 14 Fr intravenous cannula was inserted through the umbilicus to relieve the intra-abdominal pressure. An emergency laparotomy showed petechia along the anterior gastric wall, haematoma of lesser omentum but showed no evidence of gastrointestinal perforation or organ injury. Air leak test performed by insufflating air into the stomach via nasogastric tube and abdomen filled with normal saline showed no leak. On-table oesophagogastroduodenoscopy showed mild oesophagitis and petechia of cardiac gastric mucosa. He was treated with intravenous antibiotics and discharged on the fifth postoperative day with adequate analgesia.
