Author: The British Medical Association
A general term applied to any operation in which the abdominal cavity is opened (see ABDOMEN). A laparotomy may be exploratory to establish a diagnosis, or carried out as a preliminary to major surgery. Viewing of the peritoneal cavity (see PERITONEUM) through an ENDOSCOPE is called a LAPAROSCOPY or peritoneoscopy.

Laparoscope

An instrument consisting, essentially, of a rigid or ?exible cylinder, an eyepiece and a light source, which is inserted through a small incision into the abdominal cavity (which has already been distended with carbon dioxode gas). The laparoscope allows the contents of the abdominal cavity to be examined without performing a LAPAROTOMY. Some operations may be performed using the laparoscope to guide the manipulation of instruments inserted through another small incision – for example, STERILISATION; CHOLECYSTECTOMY. (See also ENDOSCOPE; MINIMALLY INVASIVE SURGERY (MIS).)... laparoscope

Ovaries, Diseases Of

Oöphoritis (infection of the ovaries) rarely occurs alone, except in viral infections such as mumps. Usually it is associated with infection of the FALLOPIAN TUBES (SALPINGITIS). It may occur as a complication of a miscarriage, a therapeutic abortion, or the birth of a baby. Cases not associated with pregnancy typically result from sexual activity: the most common organisms involved are Chlamydia, E. coli, and Neisseria gonorrhoea. Cervical swabs should be sent for culture and analgesics given, together with the appropriate antibiotics.

Failure of OVULATION is the cause of INFERTILITY in around a third of couples seeking help with conception. It may also lead to menstrual problems (see MENSTRUATION), such as an irregular menstrual cycle or MENORRHAGIA. An uncommon cause of failure of ovulation is POLYCYSTIC OVARY SYNDROME, often associated with acne, hirsutism, and obesity. Treatment depends on the symptoms. Early ovarian failure is the cause of premature MENOPAUSE. Treatment consists of hormone replacement therapy using a combination of oestrogen and progestogen.

Ovarian cysts (for example, follicular cysts) result from ovulation. They may be symptomless but sometimes cause abdominal pain, pain during intercourse or disturbances in menstruation. Twisting or rupture can cause severe pain, pyrexia (fever) and nausea, and explorative surgery – endoscopic laparotomy – may be needed to establish a diagnosis (symptoms of ECTOPIC PREGNANCY are similar). The ovary may have to be removed. Simple cysts often disappear of their own accord but a large cyst can cause pressure on surrounding structures and therefore should be surgically removed.

In young women the most common benign tumour is a dermoid cyst, while in older women, ?broma (see under UTERUS, DISEASES OF) is more common. All benign tumours should be removed surgically in order to be sure they are not malignant.

Malignant tumours may be primary (arising in the ovary) or secondary (metastases from a cancer developing in another organ). Treatment depends upon the site and type of the primary tumour.

Around 5,000 women a year are diagnosed as having ovarian cancer in England and Wales. Unfortunately it is not readily detected in its early stages; around 85 per cent of women do not see a doctor until after the tumour has spread. Early tumours present with symptoms similar to benign tumours, while late ones present with abdominal distension, pain and vague gastrointestinal symptoms. The disease is most common in menopausal women. Earlier diagnosis and treatment can be achieved by ULTRASOUND screening. Treatment is surgical, aimed at totally removing the tumour mass. Nowadays RADIOTHERAPY is only used for palliation. CHEMOTHERAPY is often given to patients with ovarian metastases, or who have residual disease after surgery. The most active cytotoxic agent is the taxane, PACLITAXEL – especially when it is combined with cisplatin.... ovaries, diseases of

Pancreas, Disorders Of

Diabetes See DIABETES MELLITUS.

Pancreatic cancer The incidence of pancreatic cancer is rising: around 7,000 cases are now diagnosed annually in the UK, accounting for 1–2 per cent of all malignancies. There is an established association with heavy cigarette-smoking, and the cancer is twice as common in patients with diabetes mellitus as compared with the general population. Cancer of the pancreas is hard to diagnose; by the time symptoms occur the tumour may be di?cult to treat surgically – with PALLIATIVE bypass surgery the only procedure.

Chronic pancreatitis may be painless; it leads to pancreatic failure causing MALABSORPTION SYNDROME and diabetes mellitus, and the pancreas becomes calci?ed with shadowing on X-RAYS. The malabsorption is treated by a low-fat diet with pancreatic enzyme supplements; the diabetes with insulin; and pain is treated appropriately. Surgery may be required.

Acute pancreatitis An uncommon disease of the pancreas which may start gradually or suddenly, usually accompanied by severe abdominal pain which often radiates through to the back. Biliary tract disease and alcohol account for 80 per cent of patients admitted with acute pancreatitis, while other causes include drugs (see AZATHIOPRINE and DIURETICS) and infections such as MUMPS. Patients are acutely ill with TACHYCARDIA, fever and low blood pressure; many go into SHOCK. The condition may be mistaken for a perforated PEPTIC ULCER, except that in acute pancreatitis the blood concentration of AMYLASE is raised. The main complication is the formation of a PSEUDOCYST. Treatment includes intravenous feeding, ANTICHOLINERGIC drugs and ANALGESICS. Regular measurements of blood GLUCOSE, CALCIUM, amylase and blood gases are required. Abdominal ULTRASOUND may identify gall-stones (see under GALL-BLADDER, DISEASES OF). If the patient deteriorates, he or she should be admitted for intensive care as haemorrhagic pancreatic necrosis may be developing. LAPAROTOMY and DEBRIDEMENT may be called for. Mortality is 5–10%.... pancreas, disorders of

Peritoneoscopy

See LAPAROTOMY.... peritoneoscopy

Abdomen, Acute

Persistent, severe abdominal pain of sudden onset, usually associated with spasm of the abdominal muscles, vomiting, and fever.

The most common cause of an acute abdomen is peritonitis. Other causes include appendicitis, abdominal injury, perforation of an internal organ due to disorders such as peptic ulcer or diverticular disease. Acute abdominal pain commonly begins as a vague pain in the centre but then becomes localized.

An acute abdomen requires urgent medical investigation that may involve a laparoscopy or a laparotomy. Treatment depends on the underlying cause.... abdomen, acute

Cholecystectomy

n. surgical removal of the gall bladder, usually for *cholecystitis, gallstones, or biliary colic. Formerly performed by *laparotomy, the operation is now usually done by *laparoscopy (percutaneous laparoscopic cholecystectomy). See also minimally invasive surgery.... cholecystectomy

Sigmoid Colectomy

(sigmoidectomy) surgical removal of the sigmoid colon using either an open approach (see laparotomy) or *laparoscopy. It is performed for tumours, severe *diverticular disease, or for an abnormally long sigmoid colon that has become twisted (see volvulus).... sigmoid colectomy

Abdominal Swelling

Enlargement of the abdomen. Abdominal swelling is a natural result of obesity and growth of the uterus during pregnancy. Wind in the stomach or intestine may cause uncomfortable, bloating distension of the abdomen. Some women experience abdominal distension due to temporary water retention just before menstruation. Other causes may be more serious.

For instance, ascites (accumulation of fluid between organs) may be a symptom of cancer or disease of the heart, kidneys, or liver; swelling may also be due to intestinal obstruction (see intestine, obstruction of) or an ovarian cyst.

Diagnosis of the underlying cause may involve abdominal X-rays, ultrasound scanning, laparotomy, or laparoscopy. In ascites, some fluid between organs may be drained for examination.... abdominal swelling

Peritonitis

Inflammation of the peritoneum. Peritonitis is a serious, usually acute, condition. The most common cause is perforation of the stomach or intestine wall, which allows bacteria and digestive juices to move into the abdominal cavity. Perforation is usually the result of a peptic ulcer, appendicitis, or diverticulitis. Peritonitis may also be associated with acute salpingitis, cholecystitis, or septicaemia.

There is usually severe abdominal pain. After a few hours, the abdomen feels hard, and peristalsis stops (see ileus, paralytic). Other symptoms are fever, bloating, nausea, and vomiting.

Diagnosis is made from a physical examination. Surgery may be necessary to deal with the cause. If the cause is unknown, a laparoscopy or an exploratory laparotomy may be performed. Antibiotic drugs and intravenous infusions of fluid are often given. In most cases, a full recovery is made. Intestinal obstruction, caused by adhesions, may occur at a later stage.... peritonitis

Dermoid Cyst

(dermoid) a benign tumour – a type of *teratoma – containing developmentally mature skin complete with hair follicles and sebaceous glands, and often pockets of sebum, blood, fat, bone, nails, teeth, eyes, cartilage, and thyroid tissue, which may give rise to symptoms of thyrotoxicosis. It is usually found at sites marking the fusion of developing sections of the body in the embryo and is the most common benign ovarian tumour in girls and young women. Sometimes a dermoid cyst may develop after an injury. Treatment is complete surgical removal, preferably in one piece and without any spillage of cyst contents. Tumours in the skin are best removed by a plastic surgeon. Because of the risks of surgery and anaesthesia to pregnant women, it is usually considered more feasible to remove bilateral dermoid cysts of the ovaries discovered during pregnancy only if they grow beyond 6 cm in diameter. The procedure is usually performed through laparotomy or very carefully through laparoscopy and should preferably be done in the second trimester.... dermoid cyst

Fetoscopy

n. direct visualization of a fetus by passing a special fibreoptic endoscope (a fetoscope) through the abdomen of a pregnant woman into the amniotic cavity. Its original use as a technique for visualizing fetal malformations and sampling fetal blood for diagnosis of blood disorders has been abandoned with advances in high-resolution fetal imaging. It is now used to facilitate minimally invasive surgery on the fetus and placenta, either under local anaesthetic or by laparotomy on the mother; the fetoscope can be directed into place using *real-time imaging. Fetoscopic laser ablation of placental vessels is now commonly used in cases of twin-to-twin transfusion.... fetoscopy

Ileus

n. intestinal obstruction, usually obstruction of the small intestine (ileum). Clinical symptoms include abdominal pain and distension, vomiting, and absolute constipation. Paralytic or adynamic ileus is functional obstruction of the ileum due to loss of intestinal movement (peristalsis), which may be caused by abdominal surgery (see laparotomy); spinal injuries; electrolyte abnormalities, particularly of potassium (hypokalaemia); peritonitis; or ischaemia. Treatment consists of intravenous administration of fluid and removal of excess stomach secretions by nasogastric tube until peristalsis returns (the ‘drip and suck’ approach). If possible, the underlying condition is treated. Mechanical ileus may be caused by gallstones entering the bowel through a fistula or widened bile duct (gallstone ileus); tumour; *intussusception; intestinal *volvulus; foreign bodies; thickened *meconium in newborn babies (meconium ileus); or parasitic infestation, for example with the threadworm Enterobius vermicularis (verminous ileus).... ileus

Laparoscopy

(peritoneoscopy) n. examination of the abdominal structures (which are contained within the peritoneum) by means of a *laparoscope. This is passed through a small incision in the wall of the abdomen after insufflating carbon dioxide into the abdominal cavity (creating a *pneumoperitoneum). Laparoscopy enables visual assessment of abdominal organs, harvesting of biopsies, and cancer staging. Therapeutic uses include aspiration of cysts, division of adhesions, and surgery that would previously have required *laparotomy. Examples include *hysterectomy, *cholecystectomy, *fundoplication, *prostatectomy, *colectomy, *nephrectomy, *oophorectomy, Fallopian tube ligation, and ova collection for *in vitro fertilization. See also minimally invasive surgery. —laparoscopic adj.... laparoscopy

Section

1. n. (in surgery) the act of cutting (the cut or division made is also called a section). For example, an abdominal section is performed for surgical exploration of the abdomen (see laparotomy). A transverse section is a cut made at right angles to a structure’s long axis. See also Caesarean section. 2. n. (in imaging) a three-dimensional reconstruction of body scans obtained by computerized tomography or magnetic resonance imaging. These are reconstituted as transverse, sagittal, and coronal plane sections. 3. n. (in microscopy) a thin slice of the specimen to be examined under a microscope. 4. vb. (in psychiatry) to issue an order for the compulsory admission of a patient to a psychiatric hospital for assessment and/or treatment of a mental disorder under the appropriate provision or section of the *Mental Health Act 1983 as amended by the Mental Health Act 2007. There are formal procedures, such as review and right to appeal, to ensure this legislation is not abused. A patient who otherwise has *capacity may still consent to or refuse treatment for conditions unrelated to the mental disorder for which he or she is detained.... section
