Several animal studies have demonstrated that pain is modulated by spinal mechanisms involving prostaglandins and that acetylsalicylic acid (ASA) administered intrathecally has an analgesic effect. We report our experience of this treatment in 60 patients with proven and advanced cancer. An isobaric solution of lysine acetylsalicylate was administered by lumbar puncture in doses ranging from 120 to 720 mg of ASA. The results were evaluated using the habitual criteria: scoring system, behaviour, consumption of analgesic drugs. In this trial the method proved astonishingly effective (78% of the cases). Analgesia was strong, almost immediate and without influence on motricity. No thermic or neurovegetative changes were noted. The effect of one injection lasted from 3 weeks to 1 month on average; it was reproduced and often more prolonged after a repeat injection. Pain associated with bone metastases seems to constitute the best indication, notably in breast and lung cancer and in myeloma. Visceral (pancreas) or neural pain requires higher doses to respond. Failures (22%) were due to such factors as insufficient dosage at the very beginning of our experience or severe depressive syndrome. The perineal and sphincteral pain of rectal cancer often resists treatment. This simple, inexpensive and very effective method with no other complication than a frequent tendency to fatigue should rank among other analgesic measures in cancer. The lack of respiratory depression is a major advantage over catheter spinal opiate analgesia. We consider that its main indications are pain associated with osteolytic metastases of adenocarcinomas, and myelomas. Owing to the absence of formal toxicological data, its use must be limited to cancer pain and to patients with a life expectancy of less than 2 years.

Chronic cancer pain remains intractable by standard treatment in many patients and interferes with their mobility and independence. Epidural morphine infusion therapy is adopted for providing adequate analgesia in patients who are generally morphine independent and have intractable pain. A totally implantable pump system, Infusaid, has allowed continuous epidural morphine infusion without wound care or frequent percutaneous injections and with a potentially lowered risk of adverse reactions including respiratory suppression. Since December 1984, the authors have used this totally implantable drug delivery system for continuous epidural morphine infusion in two patients who had been suffering from chronic pain caused by pelvic cancer associated with metastatic and/or invasive lesions: Case 1: a 61-year-old man with rectum cancer; and Case 2: a 44-year-old man with colon cancer. Before system implantation, a therapeutic response to epidural morphine was confirmed by a one-shot test injection. Pain relief was evaluated by use of Visual Pain Analogue Scale Scores (VPASS). In spite of the presence of an artificial anus on the left abdomen in both patients and of pus discharge from a sacral infectious fistula on admission in Case 2, no infectious complication occurred in either case. Urinary retention developed after the implantation in Case 2, but this improved following the reduction of morphine concentration. No other adverse reaction was observed. In Case 1, the system was effective for 6 months until his death from advancing malignancy, and the patient was able to return to work three months after discharge.(ABSTRACT TRUNCATED AT 250 WORDS)

A prospective comparison of laparoscopically assisted (n = 11) and conventional (n = 14) anterior resection in patients with sigmoid colon or upper rectal cancer was carried out. Patients were not randomized; age and the presence of metastases determined the type of surgery. Laparoscopic assistance was used to mobilize the tumour and minimize the abdominal incision. This was achieved in all patients and six of the 11 required only a muscle-splitting incision. The mean(s.d.) operating time was longer for laparoscopic than conventional surgery (205(31) versus 123(26) min, P = 0.01). The mean(s.d.) time to reintroduction of normal diet (2.5(0.2) versus 3.6(0.3) days, P = 0.01), postoperative analgesia requirement (2.6(0.4) versus 7.4(2.1) doses of pethidine, P = 0.01) and length of hospital stay (12.3(3) versus 14.3(6) days, P = 0.08) were less in the laparoscopic group. Histopathological examination of the resection specimens showed similar results for the two procedures. Major complications were few and occurred in a similar proportion of patients treated laparoscopically or conventionally. Laparoscopically assisted anterior resection is technically feasible, adequate tumour excision can be achieved and recovery after operation is enhanced.

A 70-year-old man who had undergone a low anterior resection for primary rectal cancer 9 years before complained of anorexia, hemiplegia, and recurrent laryngeal nerve palsy. The anorexia was caused by duodenal stenosis due to swollen lymph nodes, the hemiplegia was caused by a metastatic brain tumor, and the recurrent laryngeal nerve palsy was caused by metastases of the cancer to the mediastinal space. Metastases were also found in the bilateral lungs, liver, ureter, and cervical vertebra. In choosing the anesthesia for the gastrojejunostomy to improve the malnutrition of this patient, we decided, on the basis of the patient's full stomach, malnutrition, hypovolemia, hemiplegia, cerebral compression, recurrent laryngeal nerve palsy, renal dysfunction, and respiratory dysfunction, to use thoracic epidural anesthesia rather than spinal anesthesia or general anesthesia. Thoracic epidural anesthesia could provide sufficient analgesia, and the operation was uneventful. In anesthetic management of an end-stage patient undergoing a palliative operation like this, we should consider the purpose of the operation, its complications, and further complications which may be induced by anesthesia in order to plan out an anesthetic regimen unlikely to lead to harmful events in perioperative period.

The objective of this case report is to discuss the successful postoperative analgesic management in a patient who had disseminated rectal cancer pain and failed to obtain pain relief despite high-dose intravenous hydromorphone. A 45-year-old male had metastatic rectal cancer involving multiple vertebrae. After a T6 corpectomy, the patient failed to obtain effective pain relief with massive doses of parenteral opioids. The epidural catheter was placed under fluoroscopy. The patient subsequently failed to obtain relief with epidural administration of bupivacaine and hydromophone. Epidural sufentanil was used to obtain adequate pain control. Postoperative epidural analgesia is a technique worthy of consideration for patients with extreme opioid dependency for corpectomy. Epidural sufentanil can successfully be administered for postoperative pain control for patients receiving a large dose of opioids for cancer pain.

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.

Two cases with perineal pain caused by recurrent carcinoma of the rectum are reported. Initially both patients suffered from predominantly nociceptive pain, which was treated adequately with spinal opioids. Tumor growth with epidural spread and infiltration of the plexus lumbosacralis caused severe neuropathic pain. Both patients were free of pain with a combination of spinal clonidine and opioids. Clonidine doses had to be increased up to 1.31 and 1.46 mg daily in order to provide adequate analgesia. Outpatient treatment was possible for several weeks with stable dosage. Bradycardia and hypotension occurred with initial dose titration and after dose increases and were treated with parasympathicolytic drugs and vasopressor agents. Both patients were given spinal clonidine until their death 4 1/2 and 4 months later. In the final stages, adjuvant systemic administration of morphine was necessary to control dyspnea.

In this case report, we describe continuous subcutaneous infusion of opiates as PCAO (patient controlled analgesia in outpatients) in one patient with metastatic carcinoma of the rectum (liver and bone metastases, partial bowel obstruction) with severe cancer pain and vomiting in the terminal phase. The parenteral administration of opioids extended over 58 days. The infusion was powered by an external portable clockwork-driven syringe pump (Perfusor M, Braun Medical/Germany). The open-accessible pump has a syringe volume of 10 ml, and its maximal infusion time is 24 h. The 27-G infusion needle (Sub-Q-Set, Baxter/USA) was inserted in the side of the abdomen and was left in the same position for 10 to 20 days. It took the patient and his family only 1.5 h to familiarize themselves with the use of the pump. They were trained in its use in our outpatient pain department. For pain control both the variable continuous infusion and the extra injection doses could be administered by the way of the syringe driver. The patient was given a stock of 120 ampoules of morphine for further treatment at home. For optimal pain control he decided to raise the daily dose of opioid infusion from the initial 60 mg to 240 mg morphine within 48 h. In this way, PCAO-besides rapid titration of the opioid dose to achieve analgesia-allows the use of opioids controlled by the patient himself. In the present case this procedure was also important when an outpatient radiation therapy became urgently necessary to prevent a fracture of the spine because of metastasis. The pain control by the patient himself was the main factor to get free of pain during the transport to the hospital. Even positioning for radiation was possible without pain. When he received outpatient radiation therapy the patient needed extra injection doses of up to 360 mg morphine a day. The PCAO procedure by continuous subcutaneous infusion with opiates is a safe and efficient method of pain management for outpatient patients suffering from severe cancer pain and intractable nausea in the terminal phase. Its validity has also been proven especially for radiation treatment of bone metastases.

This report describes a case of rectal cancer with severe interstitial pneumonia (IP) and chronic pneumothorax. Acute exacerbation of IP is a serious postoperative complication and the consequences are extremely poor. To provide less invasive surgery and to prevent acute exacerbation of the IP, the patient received chemo-radiotherapy for controlling locally advanced tumor following low anterior resection under combined spinal-epidural anesthesia. Adequate epidural analgesia during the postoperative period had been shown and the epidural catheter was removed on the 3rd postoperative day. The patient showed symptoms of intrapelvic abscess due to the anastomotic leakage at 10th postoperative day. In order to avoid complications due to spinal and epidural anesthesia (epidural abscess, meningitis), and to prevent acute exacerbation of the IP, general anesthesia was employed with minimal fraction of inspired oxygen (FIO(2)) to perform the colostomy for the anastomotic leakage. The patient recovered without any postoperative respiratory complications. We herein report the successful perioperative management of a rectal cancer patient with severe IP and chronic pneumothorax, with special attention paid to the respiratory functions.

Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity, a shorter treatment time, and similar outcomes. However, simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature. Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort. He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected. The operation time was 270 min and the estimated blood loss was 120 mL. The patient required parenteral analgesia for less than 24 h. Flatus was passed on postoperative day 3, and a solid diet was resumed on postoperative day 7. He was discharged on postoperative day 13. With the advances in laparoscopic technology and experience, simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer.
