Mesenteric vein thrombosis: a rare cause of abdominal pain in cirrhotic patients--two case reports

Mesenteric vein thrombosis is a rare disorder which can develop rapidly with intestinal infarction or subacutely with abdominal pain due to intestinal ischemia. Despite the availability of modern diagnostic tools, which allow an early diagnosis in most cases, the mortality from this disease has not significantly diminished over the years. The problem is that the syndrome is rare and unusual and the clinical presentation is usually vague or confusing. Particularly in cirrhotic patients, this diagnosis requires the exclusion of several other complications of liver disease, like spontaneous bacterial peritonitis, tense ascites or portal thrombosis. Here, we report the occurrence of acute mesenteric vein thrombosis in two patients with liver cirrhosis. Severe subcontinuous abdominal pain out of proportion to the physical findings and abdominal distension were the major symptoms in both patients. Magnetic resonance imaging in one case and ultrasound scan with color Doppler followed by computed tomography in the other patient confirmed the diagnosis and enabled an appropriate early therapy to be undertaken.     

Wrong diagnoses of acute appendicitis in women]

In the years 1988 through 1992, 434 patients with acute appendicitis were operated at Third Department of Surgery, Medical Academy, in Kraków. The group included 201 females aged 14 to 90 years of life. In 159 women the diagnosis of acute appendicitis was confirmed, whereas 42 patients were subjected to surgical procedures due to other than appendicitis conditions located within the abdominal cavity. Surgeries prompted by symptoms suggesting appendicitis were most often performed in women with gynecological diseases. Only in several cases laparotomies were performed for other reasons. Wrong diagnoses were most often noted in women below 20 years of life and in the group between 40 and 60 years of life. The introduction of routine ultrasound examinations into the diagnostic management of acute peritonitis and diseases of the reproductive system might result in decrease of the number of diagnostic errors in acute appendicitis in women. An emergency procedure performed when the diagnosis is unclear is recommended rather than prolonged observation. The latter often results in delayed diagnosis of acute appendicitis when diffuse peritonitis develops.     

The role of laparoscopy in the diagnosis and treatment of abdominal pain syndromes

BACKGROUND: Diagnostic laparoscopy plays a significant role in the evaluation of acute and chronic abdominal pain in the era of therapeutic laparoscopic surgery. METHODS: We referred to our personal series of laparoscopy for both acute and chronic abdominal pain. This is a retrospective review of data accumulated prospectively between 1979 and the present. RESULTS: In our series, 387 consecutive patients underwent laparoscopy because of abdominal pain. In a group of 121 patients with acute abdominal pain, a definitive diagnosis was made in 119 cases (98%). Two patients needed laparotomy to confirm the diagnosis; both had a disease process that did not require laparotomy to treat. A definitive therapeutic laparoscopic procedure was performed in 53 cases 944%). In 45 patients (38%), a diagnosis was made that did not require therapeutic laparoscopy or laparotomy to treat. In the remaining 21 patients (17.5%), exploratory laparotomy was needed to treat the condition. In a chronic abdominal pain group of 265 patients, the etiology was established laparoscopically in 201 cases (76%). A definitive therapeutic laparoscopic procedure was performed in 128 patients (48%). There was a normal laparoscopic examination in 64 patients (24%). There was one false negative laparoscopy that required laparotomy to treat 1 month later. CONCLUSIONS: Laparoscopy is an accurate modality for the diagnosis of both acute and chronic abdominal pain syndromes. These data support the use of laparoscopy as the primary invasive intervention in patients with acute and chronic abdominal pain.     

Jejunum perforation following blunt abdominal trauma--a case report

We describe an intestinal perforation in a football player who had been hit with the knee in the abdomen. Perforation of the small bowel, following blunt abdominal trauma, is relatively rare. Its most frequent cause is a deceleration trauma, usually from a traffic accident. Clinical signs are frequently discrete and nonspecific. The most frequent symptom is abdominal pain. Lack of bowel sounds is reported in 64% oft the cases. Enteric lesions should be suspected in the presence of a corresponding history (deceleration trauma) and of other pathologies (fractures of vertebrae and/or pelvis). Sonography and computed tomography are rarely helpful. Delayed perforations have been described, necessitating prolonged observation for 48 to 72 h. after painful abdominal trauma. Repeated examinations are essential to rule out enteric perforation. Initially, less than 50% of the cases show free air, thus limiting the usefulness of thoracic and abdominal radiography. Mortality reaches 30%. This rate is adversely affected by concomitant lesions in other organs and by delay (more than 10 h.) in diagnosis. When laparotomy has been delayed and peritonitis is present, antibiotic treatment should be started immediately during surgical intervention (cephalosporin, aminoglycoside, metronidazole). Postoperative complications include septicaemia, wound infection and, rarely, enterocutaneous fistulae.     

The acute abdomen in spinal cord injury individuals

A review of 1300 patients with spinal cord injury (SCI), over a period of 14 years, revealed 12 patients with an 'acute abdomen'. Seven events occurred during the initial admission, ranging from 10 days to 9 months from injury, and five during readmission of 'chronic' SCI patients. Four were in the acute stage 10-30 days from injury, all with peptic ulcer perforations. The remainder had either an intestinal obstruction, appendicitis or peritonitis. All of the neurological levels were above T6 except for one patient who had a low level paraplegia. The classical signs of an 'acute abdomen' may be missing in such patients thus delaying diagnosis by 1-4 days. The most important signs were autonomic dysreflexia, referred shoulder tip pain, abdominal pain, abdominal distension, increased spasticity and abdominal pain with nausea and vomiting. Less importance was given to the classical signs of abdominal tenderness, abdominal muscle rigidity, rebound, fever and of leukocytosis. Prompt diagnosis and treatment will minimise morbidity and mortality.     

Debatable questions of surgical tactics in appendiceal infiltrates and periappendiceal abscess

The disease course in 68 patients with appendicular infiltrate (AI) and periappendicular abscess (PAA) is analysed. There were 42 men and 26 women at the age of 15-76 years. AI was detected in 12 patients, PAA-in 56 patients. In 39 patients diagnosis was made on the basis of clinical examination, laboratory tests and X-ray examination. Ultrasound examination was used in 19 cases. Conservative treatment appeared to be effective in 7 patients. The abscess developed in 4 patients. In 5 patients the diagnosis of AI was confirmed at the surgery. Opening and draining of the abscess was performed in 35 patients. The transabdominal opening of the abscess in combination with appendectomy was used in 19 patients. The median laparotomy, appendectomy and abdominal drainage were conducted in 2 patients with the break of the abscess into the abdominal cavity that led to the development of disseminated purulent peritonitis. The long-term results after the resolution of the infiltrate and opening of the abscess were analysed in 38 patients. The postoperative complications have developed in 29 patients, reoperation was performed in 7 of them. 2 of the 68 patients died after surgery. The total mortality rate was 2.9%, postoperative mortality-3.4%. Acute liver insufficiency (1) and intoxication (1) were the causes of death.

PURPOSE: The literature on diagnostic peritoneal lavage in the assessment of blunt abdominal trauma reflects an ongoing controversy. Therefore we conducted a prospective evaluation of the diagnostic management of blunt abdominal trauma used at our clinic, in which this procedure plays a substantial role. During the years 1993 and 1994 a total of 75 patients could be included in the study. The study population consisted of all patients with a diagnosis of blunt abdominal trauma. In addition, all trauma patients who were unresponsive on admission to the emergency receiving unit underwent the same program of diagnostic work-up. This group included polytraumatized patients, patients with craniocerebral injuries and all those who had been intubated prior to admission. Patients with stable vital signs were evaluated first by sonography of the abdomen, whereas those showing signs of hypovolemic shock received a diagnostic peritoneal lavage as the first evaluation of abdominal trauma. In order to assess the relative value of the two diagnostic methods, all patients who had had ultrasound as their first examination subsequently also underwent peritoneal lavage. RESULTS: 37 patients (49%) had lavage evidence of intraperitoneal bleeding. Of these 22 (29% of the total) subsequently underwent emergency laparotomy with lesions requiring surgical treatment found in 21 (95%). Only in one patient (1.3% of the study population) laparotomy failed to reveal a lesion requiring surgical correction. The accuracy of peritoneal lavage findings as an indication for laparotomy was 99%, compared to 82% for ultrasonography used as a initial diagnostic procedure. Diagnostic peritoneal lavage is quick, safe and almost independent of the experience of the investigating physician. It can be performed during other diagnostic procedures and can be repeated at will. If beyond macroscopical evaluation the lavage fluid is assessed chemically, even duodenal and pancreatic lesions as well as injuries to other hollow viscera can be suspected. With a sensitivity of 100% and a specificity of 98%, diagnostic peritoneal lavage is an extremely reliable diagnostic tool. It should be used as the initial diagnostic procedure in all hypovolemic and/or unresponsive patients suspected of having suffered blunt abdominal trauma. In conscious patients with stable vital signs, ultrasonography can be used for initial diagnosis. It should, however, be complemented by subsequent peritoneal lavage whenever the clinical course gives rise to suspicion.     

The clinical and radiological features of cholecystocolic fistulae

The clinical and radiological features of seven patients presenting with cholecystocolic fistulae are reviewed. The majority of the patients were elderly (age range 43-85 years, mean 70.7 years) and there was a female preponderance (6:1). The condition usually has a benign clinical course. Diarrhoea was the most common presenting symptom and the typical clinical features of gallbladder disease were absent. Cholangitis occurred in only one patient. The time between onset of symptoms and diagnosis varied from 1 week to 2 years (mean 22 weeks). In only one patient was the diagnosis of biliary-intestinal fistula suspected on the basis of the plain abdominal radiograph (Case 5). A diagnosis of cholecystocolic fistula was established by barium enema (5 cases), endoscopic retrograde cholangiopancreatography (ERCP) (1 case) and diagnostic laparotomy (1 case). The only cause identified in this series was acute or chronic cholecystitis.     

Pneumococcal peritonitis. An unusual diagnosis in gynecology

The authors, having had a case of primary pneumococcal peritonitis, review the features of this pathological condition which has become rare, and of gynaecological pneumococcal infections. Pneumococcal peritonitis presents as a very serious peritonitis and the usual diagnosis that is first made is peritonitis due to appendicitis. Pneumococcal peritonitis can be primary but it is possible that it is often secondary to genital pneumococcal infections. Treatment should always be by laparotomy to confirm the diagnosis, with a peritoneal toilet which is needed in order to stop a pelvic abscess developing. Antibiotics, which are usually of the penicillin group, should be given for at least 15 days. The treatment can be varied in those rare cases where cirrhotic ascites or serious nephrotic syndromes develop in children. Putting in drains and removing the appendix when it is normal are both useless.     

Capacitively coupled electrical stimulation treatment: results from patients with failed long bone fracture unions

BACKGROUND: The low incidence of stab wounds in Australasia has led to a more operative approach for the management of anterior abdominal stab wounds. A survey of Australasian surgeons interested in trauma was undertaken to analyse current practice. METHODS: Ninety-seven early management of severe trauma surgical instructors (known as ATLS in Australasia) were surveyed using a four-part, single-page questionnaire. RESULTS: Sixty-five instructors completed the survey. Thirty-nine instructors stated that they would admit patients with stab wounds even if the wound appeared superficial or 'skin only'. For 14 surgeons the decision to perform a laparotomy was dependent on fascial penetration and for 17 the decision depended upon peritoneal penetration. Six felt that all but the most superficial wounds should have a laparotomy. Laparoscopy, diagnostic peritoneal lavage and other investigations were also thought to be helpful. Thirteen surgeons felt that the presence of peritonism or tenderness were the most important determinants. There was no hospital protocol for 44 respondents and there was a wide variation in individual approach to this problem. However, all agreed that peritonism and haemodynamic instability were indications for immediate laparotomy. CONCLUSIONS: There is still a low threshold for laparotomy in Australasia and this approach is not without risks. However, the alternative of using serial observation should be regarded as an active form of management and protocols must be established to ensure regular repeat examinations by experienced personnel. The low incidence of abdominal stab wounds in Australasia makes this approach difficult. A safe approach for the Australasian situation is described.     

Solvation of human serum albumin in aqueous alkylurea solutions

In order to list the negative emergency laparotomies, the records of 24,494 laparotomies performed from 1950 to 1989 were examined. 211 negative laparotomies were performed over this 40 years period: 49 for abdominal trauma, 42 for supposed intestinal obstruction, 44 for supposed peritonitis or visceral infection, 46 for presumed early post-operative abdominal complications and 30 for gastrointestinal bleeding. Over these 4 decades, the emergency laparotomy rate and negative laparotomy rate remained stable despite changes in the diagnostic tools, in the age of the patients and the frequency of their diseases.     

Clinical considerations and therapeutic options in papillomatosis of common bile duct. Clinical case

Gunshot wounds of the abdomen are associated with a 90% or greater incidence of intra-abdominal injury, prompting many trauma centers to routinely explore these patients via laparotomy. Increasingly, diagnostic laparoscopy has been used to evaluated the abdomen to exclude peritoneal violation by the missile. Retrospective analysis of the experience at a Level I Trauma Center with 20 isolated abdominal gunshot wound patients who did not have obvious indications for laparotomy such as peritonitis or shock is detailed. Outcome and cost analysis were compared in patients who had diagnostic laparoscopy or laparotomy. Patients who underwent diagnostic laparoscopy instead of laparotomy had a 42% reduction in operative time, a 33% reduction in hospital charges, and a reduction in hospital length of stay from an average of 3.5 days to less than one day. The only operative complication noted was in a patient who underwent laparotomy. Diagnostic laparoscopy may be used in select patients to exclude significant intra-abdominal injuries following gunshot wounds of the abdomen with reduction in health care costs and morbidity.     

Abdominal catastrophe: visceral injury as a cause of peritonitis in patients treated by peritoneal dialysis

OBJECTIVE: Peritonitis is considered an acceptable and controllable risk in patients undergoing chronic peritoneal dialysis (PD). In contrast, peritonitis due to visceral leakage represents a true "abdominal catastrophe" because of striking morbidity and mortality. To delineate the incidence, causes, and outcomes of catastrophic peritonitis, we compared patients who developed peritonitis due to documented visceral leakage with patients who developed peritonitis due to enteric organisms without evidence of visceral leakage. DESIGN: Retrospective chart review. SETTING: PD Unit located in tertiary care referral center. PATIENTS: 230 patients treated by PD between January 1988 and June 1996. MAIN OUTCOME MEASURES: All episodes of PD-related peritonitis occurring over an 8-year period. Hospital course of all patients with or without renal failure who were treated at University Hospitals of Cleveland for ischemic bowel disease, cholecystitis, viscus perforation, or diverticulitis. RESULTS: Anatomically documented visceral injury caused 32.5% of episodes of enteric bacterial peritonitis in 72 patients between January 1988 and June 1996. The overall incidence of this "abdominal catastrophe" was 11.3%, or 26 of a total of 230 patients treated by PD. Of the 26 patients, 50% died, 30.7% survived but switched permanently to hemodialysis, and only 19.2% remained on, or returned to, PD. Compared to renal failure patients treated by hemodialysis or transplantation and to non-renal failure patients, the incidence of abdominal catastrophe was 20-60 times greater in patients treated by PD. CONCLUSIONS: Evidence for injury of an abdominal organ should be sought in all patients treated by PD who develop peritonitis with enteric organisms. Surgical intervention is definitive for diagnosis, and if performed early may reduce morbidity and mortality.     

Pancreatic tuberculosis in non-immunocompromised patients: reports of two cases, and a literature review

We present two cases of biopsy proven tuberculosis of the pancreas in non-immunocompromised patients diagnosed and treated in our unit within the last 14 years. The first case presented with abdominal pain and fever, and the second with iron deficiency anaemia and severe weight loss. In both cases abdominal ultrasound and computed tomography suggested a pancreatic carcinoma. There was no pulmonary or intestinal tuberculosis. The tuberculin skin test was positive. Upon exploratory laparotomy the macroscopic appearance of the pancreas was that of an inoperable pancreatic carcinoma. Following the histological diagnosis of pancreatic tuberculosis, both patients were successfully treated with triple antituberculous therapy for 6 months. Isolated pancreatic tuberculosis is an extremely rare disease with only 41 cases in non-immunocompromised patients reported worldwide (1966-1997). It is a curable disease and should be considered in the differential diagnosis of a pancreatic mass or abscess shown on ultrasound or computed tomography, especially in developing countries, where tuberculosis is common.     

Bedside diagnostic laparoscopy and peritoneal lavage in the intensive care unit

BACKGROUND: Early diagnosis and treatment of intra-abdominal pathology in critically ill intensive care unit (ICU) patients remains a clinical challenge. The objective of this study is to assess the feasibility of portable, bedside diagnostic laparoscopy (DL) in the ICU for patients suspected of intra-abdominal pathology, and to contrast its accuracy with diagnostic peritoneal lavage (DPL). METHODS: All adult ICU patients for whom a general surgery consultation was requested were eligible. Patients with a recent laparotomy or obvious peritonitis were excluded. All procedures were performed in the ICU. RESULTS: Over a consecutive 16-month period, 12 patients underwent DPL/DL. Ages ranged from 28 to 88 (mean, 72) years. Causative findings were disclosed by DL in five patients, (42%) including intestinal ischemia in two. Perforated diverticulitis, thickened terminal ileum, and nonpurulent peritonitis were found in one patient each. All patients with findings by DL had a positive DPL (WBC > 200 cells/mm3), and one negative laparoscopy was positive by lavage. The average length of time to perform DPL was 14 min, and to complete DL 19 min. One patient underwent laparotomy based on DPL/DL and survived along with three others with negative DPL/DL. Eight patients died (67%), four from their surgically untreated intra-abdominal pathology. One patient sustained a procedure-related complication of bradycardia and high ventilatory airway pressures. Peak airway pressures increased an average of 8 mmHg and were significantly higher (p < 0. 001) than pre-DL pressures without any significant change in end-tidal CO2 or pCO2. There were no statistically significant hemodynamic changes based on mean arterial pressure (MAP), central venous pressure (CVP), or pulmonary artery diastolic pressure (PADP). CONCLUSIONS: Bedside laparoscopy can be performed rapidly and safely in the ICU. In predicting the need for laparotomy, DL was more accurate than DPL.     

The role of diagnostic laparoscopy in treatment of penetrating injuries of the lower thoracic wall and anterior abdominal wall

Penetrating injuries of the lower thoracic wall and anterior abdominal wall cause difficulties in the decision for laparotomy. For gunshot wounds laparotomy without further investigations is in most cases justified, but in other penetrating traumata one should use every diagnostic modality to prevent unacceptably high negative laparotomy rates. We performed diagnostic laparoscopy (DL) on 39 patients with penetrating injuries of the anterior abdominal wall and/or lower thoracic wall. Of these 39 patients, 25 had negative and 14 positive results. We had only one false-negative finding. No false-positive result occurred. We think that DL is a very reliable diagnostic tool which requires a relatively high technology.     

Ovarian torsion as a cause of colic in a neonatal foal

A 1-week-old Morgan filly was evaluated because of acute signs of abdominal pain of 7 hours' duration. On admission, physical examination findings were unremarkable; however, radiography of the abdomen revealed slight distention of the small intestine. Signs of abdominal discomfort were detected during several hours of observation. Abnormalities were not evident during gastroscopic evaluation. Therefore, exploratory laparotomy was performed. The only abnormal finding was infarction of the left ovary secondary to a 720 degrees torsion of the mesovarium. The vascular pedicle was ligated and the ovary was removed. Recovery from anesthesia and surgery was satisfactory, and the foal was discharged from the hospital 5 days after surgery. Two years later, it appeared to be clinically normal. Review of the recent veterinary literature failed to find reports of ovarian torsion as a cause of signs of abdominal pain in horses. Ovarian torsion should be considered as a differential diagnosis in fillies with acute signs of abdominal pain, especially when laparotomy fails to reveal abnormalities associated with the gastrointestinal tract.     

Warning signals in acute abdominal disorders. Lactate is the best marker of mesenteric ischemia

An increased plasma lactate concentration (PLC) is a recognized danger signal often found in cases of shock, septicaemia, hepatic and renal failure, and diabetic ketoacidosis. In 120 patients with abdominal complaints, we found the PLC to be above normal limits in 96 per cent (24/25) of the mesenteric ischaemia subgroup, in all 20 of the general bacterial peritonitis subgroup, in 30 per cent (6/20) of the acute pancreatitis subgroup, and in about half of the 25 cases of intestinal obstruction. In all other abdominal conditions represented (n = 30), comprising various inflammatory or infectious abdominal diseases, the PLC was within the normal range. In patients with abdominal complaints, an increased PLC usually indicates the needs of emergency surgery. In the present series, the PLC manifested a sensitivity of 96 per cent and a specificity of 38 per cent as a marker of mesenteric ischaemia, and was also found to be a useful aid in the diagnosis of bowel obstruction and general bacterial peritonitis.     

Mucinous cystadenoma of the pancreas as a cause of acute pancreatitis

Acute pancreatitis is only rarely the first presentation of a cystic neoplasm of the pancreas. Mucinous cystadenomas have not been reported to be a cause of acute pancreatitis; however, we present two cases of mucinous cystadenoma of the pancreas which have caused acute pancreatitis. Both patients (female) presented acute abdominal pain, with serum amylase elevation and ultrasound scan (US) and computed tomography (CT) evidence of moderate pancreatitis, which resolved with medical treatment; fluid collection in the distal pancreas had been misinterpreted as a pseudocyst. There was no history of alcohol abuse or gallstone disease. After distal pancreatectomy the diagnosis of mucinous cystadenoma was confirmed; in one case a large pseudocyst was associated with this diagnosis. Pre-operative differential diagnosis between inflammatory and neoplastic cysts is difficult, especially when the patient's first presentation is due to an episode of acute pancreatitis. A neoplastic cyst should be considered when acute pancreatitis attacks occur in non-alcoholic women, who do not have gallstone disease.     

Sclerosing peritonitis associated with luteinized thecoma of the ovary

A unique case of bilateral luteinized thecomas of the ovary associated with sclerosing peritonitis is reported and the clinical and pathological features of this and previously reported cases are reviewed. The patient, 52 years of age, presented with abdominal distension and diarrhea. Pelvic imaging studies revealed bilateral ovarian tumors with ascites. Total abdominal hysterectomy and bilateral salpingo-oophorectomy with adhesiotomy of the small bowel were performed. Histologically, the ovarian tumor was composed of closely packed spindle to round-shaped cells, and within the spindle cell population, lutein-like cells were scattered singly or in clusters. Mitotic counts of spindle cells revealed 12 mitotic figures (MF) per 10 high-power fields (HPF) in one part of the left ovarian tumor, but other areas of the tumor showed less than 3 MF/10 HPF on average. The lesion from the resected small bowel showed prominent fibrosis, confined to the serosa with no evidence of metastasis from the ovarian tumor. The patient has undergone adhesiotomy with partial resection of the small bowel seven times since the first laparotomy because of the recurrent small bowel obstruction. The patient has survived with complications due to short bowel syndrome for 7 years after the initial surgery and so far no recurrence or metastasis of the ovarian tumor has been identified. The case reported here also supports the idea that luteinized thecoma of the ovary associated with sclerosing peritonitis may be a distinct clinicopathologic entity, in terms of the unique association and of the unique features of thecoma; that is, bilateral, hormonally inactive and apparently benign in spite of its highly mitotic activity. Additional attention should be paid to the patient's quality of life, which is often degraded by peritoneal fibrosis and small bowel obstruction.
