Bowel obstruction is a common and distressing outcome in patients with abdominal or pelvic cancer. Patients may develop bowel obstruction at any time in their clinical history, with a prevalence ranging from 5.5% to 42% in those with ovarian cancer and from 10% to 28.4% in those with colorectal cancer. The causes of the obstruction may be benign postoperative adhesions, a focal malignant or benign deposit, or relapse or diffuse carcinomatosis. The symptoms, which are almost always present, are intestinal colic, continuous abdominal pain, nausea, and vomiting. Although surgery should be the primary treatment for malignant obstruction, it is now recognized that some patients with advanced disease or in generally poor condition are unfit for surgery and require alternative management to relieve distressing symptoms. A number of treatment options are now available for the patient with advanced cancer who develops intestinal obstruction. In this review, the indications for surgery are examined, the use of nasogastric tube and percutaneous gastrostomy evaluated, and the pharmacologic approach described.

As part of a continuing audit of patients undergoing laparoscopic cholecystectomy (which now numbers over 1500) 468 of the 508 patients (92.1 per cent) operated on between October 1989 and March 1991 were studied between 350 and 988 days after the operation (mean 19 months). A questionnaire was filled in by each patient before operation and at the late follow-up visit. Eight specific symptoms were sought-non-colicky pain, colic, abdominal distension, nausea, vomiting, loss of appetite, flatulence, and dietary restriction. The result of each operation was assessed by two surgeons and by the patient. In 453 patients (96.8 per cent) the symptoms had improved as a result of the operation, but 260 patients (55.6 per cent) had some abdominal symptoms. The result was assessed as excellent in 310 patients (66.2 per cent); 143 (30.5 per cent) still had abdominal complaints but they were willing to cope with those symptoms. In 15 patients (3.2 per cent) the result was unsatisfactory. Statistical analysis of 26 preoperative variables showed few significant differences between patients with excellent results and patients with persisting or new symptoms. The percentage of patients with biliary colic was reduced from 82.9 per cent before to 6.4 per cent after laparoscopic cholecystectomy (P < 0.05), and of those with flatulence from 62.6 per cent to 45.3 per cent (P < 0.05). Flatulence persisted in 147 (50.2 per cent) of the 293 patients who had complained of flatulence before the operation, and of the 175 patients who had not complained of flatulence before surgery, 65 (37.1 per cent) reported the symptom for the first time after the operation. It appears that 'flatulent dyspepsia' after cholecystectomy has many causes, one of which may be removal of the gallbladder. It is concluded that the long-term results of laparoscopic cholecystectomy in patients with symptomatic gallstone disease were excellent but the prognosis in individual patients was unpredictable.

Although Crohn's disease (CD) is generally found in the ileum and/or colon, since the 1960s it has become evident that this chronic inflammatory disorder of unknown aetiology can affect the whole gastrointestinal tract from mouth to anus. In 0.5-13% of patients with ileocolonic CD the disease occurs in the upper gastrointestinal tract as well (i.e., from mouth through jejunum). With the radiological double-contrast technique, however, early signs of upper gastrointestinal CD may be detected in 20-40% of patients with ileocolitis. On the other hand, histologically evaluated biopsies from the lower oesophagus, body of the stomach, gastric antrum and the duodenal bulb of patients with Crohn's disease from whom the upper gastrointestinal tract is normal, according to X-ray or endoscopy may reveal lesions, which are considered to be pathologically diagnostic. Jejunal involvement occurs in 4-10% of patients with ileitis, ileocolitis or colitis. In early studies biopsies of apparently normal buccal mucosa from patients with Crohn's disease showed a significant correlation between the activity of the disease, as defined by the Crohn's Disease Activity Index, and the number of plasma cells containing IgM, suggesting a generalized activated humoral defence system during relapse. A diagnosis of Crohn's disease of the upper gastrointestinal tract can be achieved by combining recognition of clinical, roentgenographic, and endoscopic features. Provided that other causes of granulomatous involvement of the gastrointestinal tract can be excluded, non-caseating granulomas are generally accepted as the histological proof of Crohn's disease. When Crohn's disease does involve the upper gastrointestinal tract, there is nearly always concomitant disease in the small bowel or colon. Compared to patients with an ileocolonic localization, patients with Crohn's disease in the upper gastrointestinal tract more frequently have colic-like abdominal pain and/or cramps, nausea and anorexia as presenting symptoms and are younger at onset of the disease. Medical therapeutic principles are the same as for Crohn's disease elsewhere in the gastrointestinal tract. Absolute indications for surgical treatment are massive bleeding, progressive stenosis, and extensive fistula formation.

The bushmaster (Lachesis muta) of Central and South America, the world's longest pit viper, is capable of injecting a large dose of potent venom when it bites. A 28-year-old man, bitten by a 1.82 m long L. m. muta in Brazil, developed pain and oedema at the bite site, nausea, vomiting, diarrhoea and sweating. There was peripheral neutrophil leucocytosis and evidence of fibrinogen consumption with secondary activation of the fibrinolytic system. Two hours after the bite, eight ampoules of Instituto Butantan Lachesis antivenom was administered, and haemostasis was normal 24 hr later. A review of reports of 20 cases of bites in humans reliably attributed to this snake in Costa Rica, French Guiana, Brazil, Colombia and Venezuela confirms a syndrome of nausea, vomiting, abdominal colic, diarrhoea, sweating, hypotension, bradycardia and shock, possibly autopharmacological or autonomic in origin, not seen in victims of other American crotaline snakes. These, and other symptoms of bushmaster envenoming, are explained by haemorrhagic, coagulant and neurotoxic venom activities. The therapeutic efficacy of non-specific Bothrops/Crotalus polyvalent antivenoms in these cases has been unimpressive. For the treatment of bites by a snake which potentially injects a large dose (> 300 mg dry weight) of venom with a range of life-threatening activities, there is an urgent need to develop more potent specific antivenoms and to treat the dramatic and life-threatening cardiovascular symptoms.

The purpose of this longitudinal open but not comparative study was to confirm the safety and efficacy of Lysine clonixinate (125 mg) and hyoscinbutylbromide (10 mg) capsules, during a period of observation of there menstrual cycles on 30 women with uterine dysfunction due to primary or secondary dysmenorrhea. The time of evolution for primary dysmenorrhea was of 4.46 years, and for secondary was of 1.77 years. Some associated manifestations of dysmenorrhea were: nausea (92%), vomit (92%), general pain (82.1%), abdominal pain (85.7%) and headache (46.4%). Regarding to the menstrual pain intensity, at first was highly severe in 10.7% severe in 42.9%, and moderate in 46.4%. At the end of the study, only 1 of 28 patients showed menstrual pain of moderate intensity. Only three adverse effects of light intensity were found without needing treatment, related to the manifestations of gastralgia and sleepiness. The association of a spasmolytic analgesic (Lysine clonixinate and hyoscinbutylbromide bromide) on the treatment for primary or secondary dysmenorrhea, reduces and prevents the menstrual pain (colic) as well as the associated manifestations with few spasmolytic association is efficacy and safety.

Jejunostomy is a surgical procedure by which a tube is situated in the lumen of the proximal jejunum, primarily to administer nutrition. There are many techniques used for jejunostomy: longitudinal Witzel, transverse Witzel, open gastrojejunostomy, needle catheter technique, percutaneous endoscopy, and laparoscopy. The principal indication for a jejunostomy is as an additional procedure during major surgery of the upper digestive tract, where irrespective of the pathology or surgical procedures of the esophagus, stomach, duodenum, pancreas, liver, and biliary tracts, nutrition can be infused at the level of the jejunum. It is also used in laparotomy patients in whom a complicated postoperatory recovery is expected, those with a prolonged fasting period, those in a hypercatabolic state, or those who will subsequently need chemotherapy or radiotherapy. As a sole procedure it is advised for neurologic and congenital illnesses, in geriatric patients who pose difficult care demands, and for patients with tumors of the head and neck. The complications seen with jejunostomy can be mechanical, infectious, gastrointestinal, or metabolic. The rate of technical complications of the Witzel longitudinal technique is 2.1%, for the transverse Witzel up to 6.6%, for the Roux-en-Y 21%, for open gastrojejunostomy from 2%, and for the needle catheter technique from 1.5% with 0.14% mortality. The percutaneous endoscopic procedures have as much as a 12% complication rate; no figures exist for laparoscopy. The complications are moderate and severe: tube dislocation, obstruction or migration of the tube, cutaneous or intraabdominal abscesses, enterocutaneous fistulas, pneumatosis, occlusion, and intestinal ischemia. The infectious complications are aspiration pneumonia and contamination of the diet. The gastrointestinal complications are diarrhea 2.3% to 6.8%, abdominal distension, colic, constipation, nausea, and vomiting. The metabolic complications are hyperglycemia 29%, hypokalemia 50%, water and electrolyte imbalance, hypophosphatemia, and hypomagnesemia. These complications are secondary to inadequate selection of nutrition relative to the characteristics of the patient, to inadequate management of the mixture, and to deficient clinical care. The ideal jejunostomy technique depends on the material resources but more importantly on the experience of the surgeon. The benefits of jejunostomy justify the risks.

D-tagatose is a potential new sugar substitute. Ingested D-tagatose is incompletely absorbed from the small intestine; unabsorbed D-tagatose reaches the colon where it is completely fermented. In a double-blind, controlled crossover study, the gastrointestinal effects were compared following acute consumption of 40 g plain chocolates containing 20 g of sucrose, lactitol, or D-tagatose by 50 healthy adults ages 18 to 24 years. Consumption of D-tagatose was not associated with a significant increase in the frequency of passing feces, or in the number of subjects passing watery feces. However, lactitol consumption was associated with an increase in both of these occurrences. Consumption of chocolate containing D-tagatose and lactitol resulted in significant increases in colic, flatulence, borborygmi, and bloating compared to consumption of the sucrose-containing chocolate, but the majority of symptoms were described as only "slightly more than usual." D-tagatose-containing chocolate did not provoke significantly more of these symptoms than lactitol-containing chocolate. A significant number of subjects reported nausea following consumption of D-tagatose chocolate compared to the sucrose chocolate control, and multiple symptoms occurred in some subjects. Overall, these results demonstrate that a 20-g dose of D-tagatose is tolerated well in comparison to lactitol.

Copper can induce acute and chronic intoxications in humans. Copper in tap water has caused a series of severe systemic diseases in Germany in recent years (copper induced liver cirrhosis). Besides cirrhosis, another type of disease with predominantly gastrointestinal symptoms has occurred which likewise appeared to be induced by copper in tap water. - In a retrospective investigation we looked for additional indications and proof that chronic copper poisoning has been the cause of the observed gastrointestinal diseases. All patients suffering from this type of disease had copper plumbing in their houses. - The patients (children and adults) suffered from nausea, vomiting, colic, and diarrhoea. In the group of infants, one refused formula milk (prepared with tap water) and the others suffered from persistent restlessness, unexplainable screaming (especially at night) and/or long lasting diaper rash. - We accept the diagnosis of chronic copper intoxication as the cause of the gastrointestinal symptoms when at least one of the following criteria were fulfilled: 1. first manifestation, remission and relapse of the disease depend on intake and a non-intake of water containing copper, respectively. 2. hypercupric state of the patients (i.e. pathological high concentrations of the non-ceruloplasmin-bound copper in serum and/or elevated copper levels in urine) 3. signs of systemic copper intoxication in the same patient 4. signs of systemic copper intoxication or hypercupric states in members of the patient s family or in his neighbourhood (non-relatives) - We found that the disease can even be caused by copper concentrations below the allowed concentration given by the German Guidelines for Drinking Water (Trinkwasserverordnung). - The data prove that copper in drinking water can cause gastrointestinal diseases and not only the better known systemic diseases (i.e. copper induced liver cirrhosis). Copper poisoning must be considered as a possible cause of chronic gastrointestinal diseases in those countries in which copper plumbing is common.

We assessed the feasibility of safe discharge home within 24 hours following laparoscopic hysterectomy in 30 patients who met the inclusion criteria and consented to be enrolled in the study group. Patients were admitted on the day of their surgery with the expectation of discharge within 24 hours. Appropriate home nursing follow-up and phone contact by the surgical team were organized preoperatively. Inclusion criteria were: age 30-65 years, absence of any major medical history that would require prolonged hospitalization, availability of home support for the first 48 hours after discharge and presence of a working telephone line and an address within the area of the Community Home Nursing service. All 30 operative procedures were completed without incident. Six patients underwent total laparoscopic hysterectomy (TLH) (all the procedures of hysterectomy being performed laparoscopically including the suturing of uterine arteries, colpotomy and closure of the vaginal vault. The uterus was removed vaginally) and 24 patients underwent laparoscopic hysterectomy (LH) (this techniques differs from TLH in that the colpotomy was performed laparoscopically but the uterosacral ligaments were divided vaginally and the vault also was closed vaginally after the uterus was removed vaginally). The average operating time was 115 minutes (range 85-150 minutes) and the average blood loss was 97 mL (20-250 mL). There were no intraoperative complications, no requirement for transfusion and no readmission to hospital for any of the patients in the study. Postoperative complications were minor (umbilical cellulitis (1), intestinal colic (1)) and both were treated with resolution of the symptoms. Ninety per cent of patients in the study were discharged within 24 hours of their surgery, the average duration of stay being 22.9 hours (20-24 hours). Three patients were not fit for discharge at 24 hours postoperatively due to general lethargy, migraine and nausea; their average discharge time was 53.5 hours. The study showed that laparoscopic hysterectomy can be associated with a reduction in length of in-patient stay compared to traditional laparotomy. Furthermore this reduction could be safely reduced to 24 hours following laparoscopic hysterectomy. There was also an associated cost saving in terms of inpatient bed days. Patient satisfaction with this protocol was high in this selected and motivated group.

Meperidine was the first synthetic opioid agent. It acts mainly as an antagonist of mu (#m) receptors and has an analgesic potency ten times greater than that of morphine. Like other opioid drugs, meperidine causes nausea, vomiting, urinary retention and respiratory depression; a point of difference, however, is that it acts on nerve fibers and has properties similar to those of local anesthetics. It has therefore been used as an alternative to other opioids for anesthetic blockade. We review the indications and contraindications of meperidine administered by different routes. For pain, epidural administration has proven to be a good alternative to intravenous administration and epidural meperidine has been combined with local anesthetics using lower doses of both drugs and producing fewer side effects. Intradural meperidine has been used as the sole anesthetic agent in various types of surgery, its principal advantage being that it provides long-lasting postoperative analgesia. Spinal meperidine has the advantage over morphine of a lower incidence of respiratory depression, particularly late-occurring depression. An intravenous route has been used for treating moderate to severe pain, for regional anesthesia, for premedication and for analgesia during anesthesia. Meperidine's action on kappa receptors has meant that it is considered the most effective drug for treating postanesthetic trembling. Although meperidine has been used effectively to treat non-surgical pain, mainly from colic, this review focuses on its usefulness in the perioperative period.
