The value of pre-therapy peritoneoscopy in localized ovarian cancer.

Because of the recent reports indicating the high incidence of unsuspected diaphragmatic metastases in presumed localized ovarian cancer, we have carried out peritoneoscopy on 14 consecutive patients referred with the diagnosis of Stage I or II ovarian cancer. Of the 14 women none was demonstrated to have diaphragmatic metastases, but 35 per cent were found to have cytologic washings demonstrating malignant cells. The significance of these findings is discussed.

Flexible transgastric peritoneoscopy: a novel approach to diagnostic and therapeutic interventions in the peritoneal cavity.

BACKGROUND: A novel endoscopic peroral transgastric approach to the peritoneal cavity was tested in a porcine model in acute and long-term survival experiments. METHODS: Transgastric peritoneoscopy was evaluated in 50-kg pigs. After upper endoscopy, the peritoneal cavity was accessed by needle-knife puncture of the gastric wall, followed by extension of the incision either with a pull-type sphincterotome or by balloon dilation. The peritoneal cavity was examined, and a liver biopsy specimen was obtained. The gastric wall incision was closed with clips. OBSERVATIONS: Twelve acute and 5 survival experiments were performed. Both techniques of gastric wall incision were without complication. The acute experiments demonstrated the technical feasibility of the approach. In the survival experiments, all pigs recovered and gained weight. CONCLUSIONS: The peroral transgastric approach to peritoneal cavity technically is feasible and has the potential to be an alternative to laparoscopy and laparotomy.

Peritoneoscopy and pancreas biopsy in the diagnosis of pancreatic diseases.

Peritoneoscopy and pancreatic biopsy under direct vision were performed on 124 cases with a variety of pancreatic diseases by means of supragastric pancreoscopy and supragastric bursoscopy. Among 53 cases of pancreatitis, the pancreas was directly observed in 38 (72%). Among 71 cases of pancreatic carcinoma, observation of pancreas head carcinoma was accomplished in 32% and for pancreas body carcinoma, 85%. Peritoneoscopic biopsy of the pancreas had good diagnostic accuracy with negligible complications.

Retro-peritoneoscopy: anatomical rationale for direct retroperitoneal access.

Although the upper urinary tract resides at an extraperitoneal location, the traditional laparoscopic approach to these organs has been transperitoneal. Several investigators have advocated using a direct approach to the retroperitoneum to minimize risks associated with transperitoneal surgery. We performed autopsy and radiographic studies in an effort to define the location of the retroperitoneum relative to surface anatomy. These investigations indicate that the peritoneal reflection was consistently anterior to the posterior axillary line. Moreover, when a patient was placed in the lateral position, the anteroposterior extent of the potential retroperitoneal space increased 2-fold. Based on these studies, a technique for direct retro-peritoneoscopy was initiated and successfully performed in 21 of 23 patients. Direct access to the retroperitoneum can be performed in a reliable and safe manner.

Peritoneoscopy as an aid in intravenous injection of indocyanine green (ICG).

Peritoneoscopy as an aid in intravenous injection of indocyanine green (ICG) was clinically evaluated. Hepatic parenchyma was stained after intravenous injection of ICG, while interstitial connective tissue, fatty deposition and hepatoma tissue were not. Regenerative hepatic cell mass including dark reddish patchy marking (Shimada's code No. 7) and semispherical areas of regeneration or nodules (Shimada's code No. 8) was well stained and clearly contrasted. There were some cases of chronic active hepatitis, in which liver surface showed spotty staining at sites expected to become regenerative nodules in the future, in contrast to being judged as "no abnormal findings" peritoneoscopically. On the other hand, periportal reddish marking (Shimada's code No. 4) representing piecemeal or bridging hepatic cell necrosis was not stained.

Biopsy evaluation of chronic active hepatitis. Peritoneoscopy with directed liver biopsy versus blind percutaneous liver biopsy.

In this prospective study of chronic active liver disease, we compared the assessment of hepatic histology in samples obtained by peritoneoscopy with directed liver biopsy and blind percutaneous liver biopsy in 23 cases (22 patients, one patient studied twice). In blinded fashion, a pathologist assessed all specimens for evidence of cirrhosis and degree of necroinflammatory change. Two clinicians independently reviewed clinical and laboratory findings in both sets of biopsies. Each committed in writing recommendations regarding immunosuppressive therapy, follow-up interval, and rebiopsy date. The final diagnosis differed from that made by percutaneous and directed biopsy in 2 of 23 (9%) and 1 of 23 (4%) cases, respectively. Six cases of cirrhosis were correctly diagnosed by both biopsy methods, but only four of the six cirrhotic cases were diagnosed by gross peritoneoscopic findings. In only 2 of 23 (9%) cases was there disagreement in the degree of necroinflammatory change between the blind and directed biopsies that affected treatment recommendations. We conclude that blind percutaneous biopsy adequately diagnoses and monitors activity in viral chronic hepatitis for treatment purposes.

Presentation and role of peritoneoscopy in the diagnosis of tuberculous peritonitis.

This study represents the clinical and laboratory features of 135 tuberculous peritonitis cases in whom peritoneoscopic investigation was used routinely. Disease was more common in women than men (1.5:1) and was most frequently encountered in the third and fourth decades in life. The most common presenting symptoms were abdominal distension (96%), abdominal pain (82%), weight loss (80%), weakness (76%), loss of appetite (73%) and fever (69%). The most common physical findings were ascites (96%), fever (75%) and abdominal tenderness (43%). One hundred and twenty-nine cases (95.5%) showed exudative type tuberculous peritonitis with variable amounts of ascites and filmy adhesions. In six patients (4.5%) the disease was of the plastic (dry) type. Peritoneoscopic investigations of 139 patients suggested tuberculous peritonitis but four cases showed histologically proven malignancy (3%). Laparoscopic diagnoses of the remaining cases were confirmed by histology (97%). The laparoscopic appearance of scattered yellowish-white nodules, approximately 1-5 mm in size, on the peritoneal surfaces, and filmy adhesions were suggestive of tuberculous peritonitis. A non-fatal colon perforation occurred as a major complication. After antituberculous therapy patients were followed for at least 1 year. Peritoneoscopy with simultaneous biopsy is the ideal and most accurate diagnostic modality in the diagnosis of tuberculous peritonitis.

Symptoms and investigative findings in 145 patients with tuberculous peritonitis diagnosed by peritoneoscopy and biopsy over a five year period.

This study analysed clinical features and laboratory investigations in 145 patients with tuberculous peritonitis diagnosed by peritoneoscopy at this hospital between 1984 and 1988. Tuberculous peritonitis was found in 2% of all patients with tuberculosis and in 59.8% of all those with abdominal tuberculosis admitted to the hospital during the study period. Tuberculous peritonitis was more common in women than men (1.4:1) and was most frequently encountered in the third and fourth decades of life. The commonest presenting symptoms were abdominal swelling (73.1%), fever and night sweats (53.8%), anorexia (46.9%), weight loss (44.1%), and abdominal pain (35.9%). The mean duration of symptoms was 1.5 months. Ascites was the commonest (95.2%) physical sign. Tuberculin skin testing was positive in 57.6% of patients (n = 118). The mean erythrocyte sedimentation rate was 75 mm/1st hour (n = 58). Chest radiography on 98 patients showed pleuropulmonary pathology in 40 patients (40.8%). Sputum examination confirmed active pulmonary tuberculosis in 26 patients. The ascitic fluid was an exudate in 96.4% and a transudate in 3.6% of patients, with 91.3% showing a straw coloured ascites. Cirrhosis, detected by biopsy specimen, was a finding in 6.2% of patients.

Detection of liver metastases in small-cell lung cancer: a comparison of peritoneoscopy with liver biopsy and ultrasonography with fine-needle aspiration.

Liver evaluation of 131 patients with small-cell lung cancer (SCLC) was performed both by peritoneoscopy (PS) with liver biopsy and by ultrasonography (US) with fine-needle aspiration. A total of 33 patients (25%) had liver involvement, 82% detected by US and 76% detected by PS. The difference was due to 27 incomplete investigations by PS and two incomplete investigations by US. In 104 patients in whom both investigations were "successful," PS confirmed 86% and US confirmed 79% of the patients with liver metastases. In each of the investigations, 7% (PS) and 14% (US) of patients had false-negative conclusions as compared with histologic evidence obtained by the other method. US found six patients with extrahepatic intraabdominal disease, while PS found none. S-lactic dehydrogenase (s-LDH), SGOT, and s-alkaline phosphatase were found to be too unspecific to indicate liver metastases unless all three tests were normal or abnormal. It is recommended that US should be used as the initial procedure when staging patients with SCLC, and that PS can be considered complementary in patients with negative US.

Peritoneoscopy of alcoholic liver cirrhosis in comparison with non-alcoholic liver cirrhosis.

Peritoneoscopic findings of 39 patients with alcoholic liver cirrhosis (ALC) were compared with those of 95 patients with non-alcoholic liver cirrhosis (NALC). They were selected from 245 patients with liver cirrhosis subjected to peritoneoscopy in the 7 year period from 1975 to 1981. Out of the 95 NALC patients, 24 had hepatitis B surface antigen. The ALC patients had nodules which varied in size (61%), large depressions (69%), and a markedly rounded edge of the liver (33%) more often than NALC patients (18, 43 and 3%, respectively). Nodularity differed between the right and left lobes in ALC (41%) more often than in NALC (16%). Interstitial reddish markings and patchy nodules were, however, more frequent in NALC (51 and 28%, respectively) than in ALC (8 and 5%, respectively). Lymphatic vesicles were observed both in ALC (85%) and NALC (78%). In conclusion, the peritoneoscopic features which suggested ALC were the coexistence of nodules of various sizes, large depressions and a markedly dull edge of the liver. Interstitial reddish markings and patchy nodules were more indicative of NALC than ALC.

Puncture of the gallbladder during peritoneoscopy - technique and diagnostic relevance (author's transl).

Peritoneoscopic puncture of the gallbladder for transvesical cholecysto-cholangiography and for aspiration of bile for chemical and bacteriological analysis is performed rather rarely because of a seemingly high rate of complications. The risk however is low if an appropriate technique is used. In our series the gallbladder was punctured in 110 cases; a local peritonitis subsiding under conservative treatment occured as a complication in only one case. Peritoneoscopic puncture of the gallbladder is indicated in the following conditions: extrahepatic occlusion of the bile duct system of unknown origin, nonvisualization of the gallbladder during cholangiography, biliary dyskinesia, typical biliary colics with normal X-ray findings. In addition, gallbladder puncture should be done if any suspicion of gallbladder disease arises during peritoneoscopy. The procedure as well as technical variations for cholecysto-cholangiography and for X-ray investigation of the pancreatic duct system are described.

[Risk and complications in peritoneoscopy].

The work is based upon the authors' 10 years' experience with more than 1500 examinations. 87 of them were combined with target biopsy of visceral organs and 5--with target cholecystocholangiography. Peritoneoscopy is not free of complications. Being a surgical procedure, it requires a special surgical skill.
