A 21-year-old man with a history of hereditary angioedema presented with protracted abdominal pain which failed to respond to infusion of C1 inhibitor concentrate. Evaluation by CT scan revealed extensive colorectal intussusception requiring surgical intervention. Under replacement therapy with C1 inhibitor concentrate, both the operation under general anesthesia and the postoperative phase were uneventful. The intraoperative examination suggested initiation of intussusception by local mucosal edema in the transverse colon.

Colorectal cancer has continued to increase in incidence over the past 25 years. It now ranks as the second most common noncutaneous malignancy for men and women together. The projected 1995 statistics predict 153,000 new cases in the United States, with 109,000 of colonic origin and 44,000 cancers of the rectum. The shift to more proximal colonic involvement and a decrease in size of the presenting lesion is again noted. Unfortunately, the warning signals (rectal bleeding, change in bowel habits and, later, abdominal pain, distention, and weight loss), often become evident only after the tumor has progressed significantly in the patient. Despite improvements in endoscopic detection, anesthesia, pre- and postoperative care and more extensive en-bloc resections, the cure rate for all patients with colorectal cancer remains unchanged at 53 per cent at five years. Although radical resectional surgery is relied on for locoregional control of the disease, there has been an increased use of cross-sectional radiologic studies for staging of the cancer. This newer management of colorectal cancer is the result of a better understanding of the natural history and biologic behavior of the cancer. The main strategy presently is to diagnose the disease sooner, stage the cancer more accurately, select tumors that will respond to adjuvant therapy, and detect recurrences more efficiently. It is in the area of staging of the primary tumor and accurate localization of recurrences that this new modality, immunoscintigraphy, is felt to have an impact.

The analgesic efficacy and duration of action of tenoxicam, an injectable non-steroidal analgesic with a long elimination half-life, were studied in day case laparoscopy in a double-blind randomised prospective parallel placebo-controlled trial. Tenoxicam 20 mg or saline was given intravenously at induction of anaesthesia in 67 women undergoing day case investigative laparoscopy for infertility or abdominal pain. Outcome measures were time to first analgesia, pain levels at 2, 4 and 24 h plus postoperative analgesic consumption in hospital and at home. The study showed no statistically significant difference in any of these measures between the two groups. Tenoxicam 20 mg intravenously immediately pre-operatively cannot be recommended for day case surgery on the basis of this study.

We have studied the cardiorespiratory changes produced by abdominal wall elevation (AWE) or carbon dioxide pneumoperitoneum (PN) in 20 women undergoing gynaecological laparoscopy. Arterial pressure, heart rate, lung/chest complicance and blood-gas tensions were measured 10 min after induction of general anaesthesia (T0), 10 min after abdominal distension in the supine position (T1) and 10 min after the Trendelenburg position was assumed (T2). Visual analogue scores for pain were recorded 1 and 6 h after the end of surgery. We found that lung/chest compliance was reduced significantly in group PN at T1 and T2 compared with both T0 and group AWE. Diastolic arterial pressure increased significantly in group PN at T1 and T2 compared with both T0 and group AWE, while it remained unchanged in group AWE. Arterial PCO2 increased significantly only in group PN after pneumoperitoneum, while oxygenation was almost unchanged in both groups. AWE patients had greater abdominal pain 1 h after surgery. Six hours after surgery pain was similar in the two groups. These data indicate that abdominal wall elevation reduced pulmonary compliance less than a pneumoperitoneum in patients undergoing gynaecological laparoscopy.

This study evaluates the safety and role of laparoscopy in the diagnosis of blunt abdominal trauma in children. Laparoscopy was performed in five patients aged 3 to 13 years because of persistent abdominal pain after blunt trauma. A laparotomy was not indicated from the physical examination, laboratory data, or radiologic findings. With the patient under general anesthesia, a 10-mm trocar was inserted through the umbilical fossa and the intra-abdominal organs were observed for 10 - 60 min under an insufflation pressure of 10 - 12 mmHg. The patients remained hemodynamically stable without pneumothorax development. Three patients underwent laparatomies: one, who had blood in the omental sac, had a duodenal injury with hemorrhagic necrosis and underwent a resection; one with ascites and high amylase levels had an injury of the main pancreatic duct and underwent resection of the pancreatic tail; and one who had fresh blood in the upper abdomen and Douglas' pouch had a splenic hemorrhage and underwent hemostasis. The other two had serous or serosanguinous ascites and recovered without surgery. In patient 1, the same amount of information might have been obtained from a barium study. In patient 2, the pancreatic transection might have been diagnosed from ascites shown on serial computed tomograms. Patient 3 might also have been treated successfully non-surgically. It hus appears that laparoscopy may be a safe diagnostic method for blunt abdominal trauma in children, however, this small series has yielded insufficient information to assess its usefulness in making the diagnosis and the decision for laparotomy. Further studies are required to ascertain whether it will make any significant difference in the form of management.

In total 199 oesophago-gastro-duodenoscopies (OGD) were performed in 71 female and 71 male paediatric patients (three months-15 years, median 8 years 2 months). The endoscopy was performed in general anaesthesia in children less than five years old, and in an intravenous sedation in older patients. The indications for OGD were: recurrent abdominal pain and concomitant positive antibodies against Helicobacter pylori as a part of a scientific project, upper dyspepsia, upper gastrointestinal bleeding, failure to thrive, coeliac disease, suspicion of chronic inflammatory bowel disease and a percutaneous gastrostomy. Seventy-two OGD were carried out in general anaesthesia, 86 in intravenous sedation with midazolam and pethidine and 41 in intravenous midazolam sedation. Complications related to the sedation or to the endoscopy were not observed. Amnesia was reported in 94/95 children who were sedated intravenously with midazolam and pethidine or midazolam alone. Six endoscopies could not be carried out in intravenous sedation because of agitation. In the primary OGD endoscopy revealed a normal mucosa in 121/142 (85%), oesophagitis in four (3%), nodular mucosa in six (4%), gastritis in four (3%) and a duodenal ulcer in one (0.7%). Histology disclosed active or inactive chronic gastritis at the primary endoscopy in 35/69 (51%) of the children with recurrent abdominal pain and antibodies against H. pylori. In children with failure to thrive an avillous duodenal mucosa was seen in 3/32 (9%). A comparison between histological and stereomicroscopical evaluation of the duodenal biopsies revealed agreement in 41/47 (87%). We conclude that OGD is a safe and tolerable procedure in paediatric patients, in whom possible morphological changes are suspected. The indications for an OGD need further evaluation.

Presented is the case of a 37-year-old South Australian woman who experienced intractable pelvic pain following laparoscopic sterilization with Filshie clips. The pelvic anatomy was normal and one Filshie clip was applied to each Fallopian tube. The patient stated she had experienced right-sided lower abdominal pain that radiated down the anterior part of her right thigh since regaining consciousness after general anesthesia. The pain had failed to resolve seven days after the procedure and the patient was unable to perform even simple tasks. Analgesics provided only temporary, partial relief. There were no signs of infection or any other exacerbating condition. At diagnostic laparoscopy, instillation of bupivacaine around the clip provided transient relief, but the pain returned the next day at the same level of severity. After one month of intractable pain, laparoscopic bilateral salpingectomy was performed to remove the clips and the pain disappeared. Although back pain has been reported in up to 14% of women undergoing laparoscopic sterilization, this is the first published case of long-term abdominal pain associated with the Filshie clip.

The acute hepatic porphyrias are rare pharmacogenetic diseases inherited as autosomal dominant conditions of low penetrance. The genetic defect is a 50% deficiency of an enzyme of the haem biosynthetic pathway. Patients may develop 'neurovisceral attacks' which include severe abdominal pain, neuropsychiatric manifestations and potentially fatal respiratory paralysis. Attacks occur generally after puberty, are much commoner in females and may be precipitated by endogenous hormonal changes, dieting, alcohol, severe infections, and many drugs. Treatment includes analgesia, early administration of haem, and general supportive measures. Patients are at greater risk of a severe attack on first presentation since an abdominal emergency may be simulated and inappropriate medication, including that for general anaesthesia may exacerbate the crisis. The urine should be tested for raised porphobilinogen, which is pathognomonic of the acute attack, if there is the slightest doubt about diagnosis. The genotype of blood relatives of index cases must be determined so that carriers may avoid drug and other precipitants. Some drugs have been established as safe or unsafe by clinical use, but information about many drugs is not available or is based only on their properties in rodents or in tissue culture systems. The relevance of these to the human condition remains controversial, but drugs shown to be porphyrinogenic in animal systems should be avoided if there is a known safe alternative. Where it is essential to use a drug not known to be safe, close biochemical and clinical observation may warn of an impending attack.

A large trichobezoar has been traditionally removed by open surgery, which has entailed an upper abdominal incision. With the advent of laparoscopic surgery, it became feasible to retrieve a foreign body from the stomach without the necessity of a large skin incision in the upper abdomen. A 7-year-old girl presenting with abdominal pain, nausea, and appetite loss was admitted and evaluated. Results of an upper gastrointestinal series showed a large mass in the stomach that extended into the duodenum. Endoscopical removal had been tried twice under general anesthesia and resulted only in the retrieval of the small portion of the trichobezoar in the duodenum; total removal seemed impossible with endoscopic techniques. Laparoscopic removal was then under-taken to avoid the surgical scar in the upper abdomen. The trichobezoar was successfully retrieved through a gastrotomy and removed via a small suprapubic incision. This approach may be the treatment of choice for future cases of trichobezoar when surgery is indicated.
