[The use of laparoscopy in the staging of stomach cancer].

Laparotomy is still being resorted to on a large scale to diagnose stomach cancer. This surgical intervention causes unjustified trauma and often exacerbates patient's condition. In a comparative study, postoperative complications were recorded in 13% of cases of laparotomy. The death rate was 2%. Patients were confined to hospital for an average of 15 days. Laparoscopy was performed in 105 patients for staging stomach cancer during clinical examinations. Metastases to abdominal cavity organs were detected in 61.9%. Laparoscopy did not involve complication or lethality. Patients stayed at the hospital not more than 5 days. A retrospective analysis of 193 cases of stomach cancer who had undergone diagnostic laparotomy showed that surgery could have been avoided in 42.5%, if laparoscopy had been used during clinical examination.

Diagnostic gastrointestinal laparoscopy: experience and changing indications.

We reviewed the records of all 117 patients who underwent diagnostic laparoscopy at our clinic from 1980 to 1985. There were no deaths or marked complications from the procedure. Accurate diagnosis was made in 72% of 79 patients with abdominal pathology; of these, 81% of 63 patients had hepatic pathology, and 44% of 16 patients had extrahepatic pathology. Of 27 patients with conditions that might have justified exploratory laparotomy, diagnosis was made in 48%. Of 29 patients who underwent preceding nondiagnostic blind-needle biopsies of the liver, laparoscopy established a diagnosis of cirrhosis or neoplasm in 44%. A parenthetical finding was that at our institution liver scan alone appeared to be the most adequate imaging workup of suspected hepatic disease. Our data support the use of laparoscopy for diagnosis of hepatic disease and as a first step prior to purely diagnostic laparotomy.

[Emergency laparoscopy in the examination of middle-aged and elderly patients with acute surgical diseases of the abdominal cavity].

Urgent laparoscopies were performed on 566 elderly and senile patients suspected of acute surgical diseases of abdominal organs. Laparoscopic examinations proved to be highly informative in 90.4%, little informative in 6.6%, erroneous in 3% of cases. Wide use of urgent laparoscopies in elderly and senile patients allowed to avoid laparotomies in 62.3% of the cases. High curative-diagnostic efficiency of laparoscopies added by laparoscopic cholecystostomy and antegrade cholecystocholangiography in patients with acute cholecystitis, cholecystopancreatitis, mechanical jaundice has been shown.

Complementary use of hysterosalpingography, hysteroscopy and laparoscopy in 100 infertile patients: results and comparison of their diagnostic accuracy.

While there is no disputing the invaluable role of laparoscopy in the study of the infertile woman, the function of hysterosalpingography (HSG) and hysteroscopy is still left open to debate. Our research concerns 100 infertile women undergoing HSG, hysteroscopy and laparoscopy; the aim of the study was to check the diagnostic accuracy of the three tests. The sensitivity and specificity of HSG vs hysteroscopy were 74.2% and 91.3% respectively. The sensitivity and specificity of HSG vs laparoscopy were 64.5% and 63.3% as regards tubal patency and 6.9% and 92.8% in the diagnosis of tubal phimosis and pelvic pathology. Despite the limits HSG revealed, our results show that a correct study of the infertile woman can only be accomplished by a combination of all three tests; we therefore recommend a combined approach using all three procedures in all infertile patients.

Laparoscopy for screening and early diagnosis of ovarian cancer.

Authors examined validity of laparoscopy for early diagnosis of ovarian cancer. They studied 144 cases of patients with benign neoplasia diagnosed by clinical examination and found ten cases of ovarian cancer by laparoscopy. They point out validity of laparoscopy indicated as a present day essential technique for early diagnosis of ovarian cancer.

Bowel injuries during laparoscopy. Gross anatomy and histology.

Bowel injuries during laparoscopy can result from either electrical damage or direct trauma. When electrocoagulation is used with laparoscopy, it is frequently assumed that any bowel injury is from that source. That assumption might not be accurate. In animal studies we evaluated the histologic characteristics of both electrical and traumatic bowel injuries. A consistent difference in injury pattern, both gross and microscopic, was noted. With a high degree of accuracy, those histologic and gross characteristics can be used to distinguish traumatic from electrical injuries following operative laparoscopy.

Laparoscopy.

In the last five years, laparoscopy has become increasingly popular in North America. The procedure has been mainly embraced by the gynecologist and its use in this field has largely supplanted culdoscopy. Other specialties, nevertheless, have been slower in recognizing its value.The procedure has wide applications in gynecology. In pediatrics, laparoscopy proves useful in elucidation of amenorrhea, intersex and precocious puberty. In general surgery, laparoscopy has been recognized as a useful tool in the patient with multiple trauma, and in establishing the diagnosis of many intra-abdominal conditions.Numerous perlaparoscopic operative procedures which include biopsies and tubal sterilizations may be carried out by an experienced operator. Complications associated with the procedure are few, but may be severe. These can be avoided by careful adherence to proper technique.

Laparoscopy and biopsy in malignant liver disease.

Laparoscopy is highly effective in diagnosing malignant liver disease, with overall accuracy in the 90% range. Up to 80% of the liver surface can be inspected, and biopsies can be directed with precision. A major advantage over scan guided percutaneous techniques is the ability to detect and biopsy lesions only a few millimeters in size on the liver surface. Laparoscopy is useful in staging the liver for metastatic disease during evaluation for treatment of primary cancers. Small peritoneal metastases may also be discovered and biopsied. Primary liver cancers and isolated metastatic deposits can be assessed for resectability, and diagnostic laparotomy can often be avoided. Laparoscopy is safely performed under local anesthesia and mild sedation.

Evaluation of adhesion reformation by early second-look laparoscopy following microlaser ovarian wedge resection.

Early second-look laparoscopy, done 6 to 12 weeks postoperatively, was utilized to evaluate recurrent adhesion formation following microlaser ovarian wedge resection. Forty-nine ovaries in 25 consecutive infertility patients undergoing microlaser surgery for deep ovarian endometriosis or polycystic ovarian disease, refractory to medical treatment, were evaluated from October 1981 through March 1983. All patients subsequently underwent a second-look nonlaser laparoscopy to evaluate the extent of healing and to bluntly lyse any subsequent adhesions with the Olympus laparoscope (Olympus Corporation, Lake Success, NY) second-puncture probe: 36.7% of the ovaries had recurring adhesions, 83.3% of these adhesions were mild and filmy and 16.7% were moderate and dense. Additionally, four ovaries were viewed approximately 1 year postoperatively, with two ovaries that previously had mild and filmy adhesions lysed at 6 weeks having no recurrent adhesions. The actual pregnancy rate in this study is 60%, with 15 of the 25 patients conceiving at least once and 2 patients conceiving twice. The majority of pregnancies occurred within the first 6 months postoperatively, with the longest initial pregnancy occurring 22 months postoperatively. Thus, microlaser ovarian surgery, coupled with early second-look laparoscopy, appears efficacious in minimizing adhesion reformation and seems to have little adverse effect on subsequent conception.

[Laparoscopy in children with intestinal obstruction].

The authors have performed laparoscopy in 30 children suspected in acute intestinal obstruction. At the present time laparoscopy is believed to be the method enabling the disease to be diagnosed at early stages sufficiently exactly and for a short time. In a number of cases the authors succeeded in liquidating acute intestinal obstruction by menas of a laparoscope and a manipulator without a repeated laparotomy. The authors recommend to use laparoscopy more frequently in acute intestinal obstruction both with diagnostic and curative aims.

Open laparoscopy with conventional instrumentation.

Forty women who had undergone previous abdominal surgical procedures were evaluated by open laparoscopy with a simple technique that required no special instrumentation. Gynecologic problems included infertility, suspected endometriosis and/or pelvic adhesions, ovarian cysts, and second-look laparoscopy after treatment for ovarian cancer. The technique was evaluated in regard to ease of performance in patients with various abdominal incisions. Conventional instrumentation was used. No significant side effects were experienced and anesthesia time was prolonged by no more than 10 to 20 minutes in most cases. Significant subincisional adhesions were found in 35% of patients. It is suggested that open laparoscopy in patients who have had previous abdominal surgery deserves reevaluation.

[Laparoscopy in diseases of the extrahepatic bile ducts].

Nearly regularly the laparoscopy gives the possibility of a free vision to the gall-bladder and a reliable judgment of pathologic changes. Indications are above all clarification of the causes of cholestase, negative cholangiogram, relapsing, particularly bland chronic cholecystitis. Apart from its diagnositsc evidence the laparoscopy is able to give references to the further therapeutic approach. Laparoscopy is further indicated in suspicion of a malignant tumour. The direct and transhepatic puncture of the gall-bladder for the radiological description of the biliary ducts was no more dealt with; ERC and PTC are to be preferred to these methods.

Evaluation of blood cultures following laparoscopy.

To determine the incidence of transient bacteremia associated with laparoscopy, a prospective study was carried out in 113 patients with diverse liver diseases. Blood samples for aerobic and anaerobic cultures were obtained for each patient immediately before laparoscopy, within three minutes after creation of pneumoperitoneum and within three minutes after needle biopsy of the liver. Five subjects were culture positive, and all isolates were of the propionibacterium species. Positive cultures did not correlate with the nature of underlying liver disease, and none of these patients developed clinical evidence of bacterial infection. Positive isolates might be assumed to be contaminants, but the fact propionibacterium has been known to cause endocarditis cannot be ignored. Until further evidence accumulates, antibiotic coverage in "high risk" patients with cardiac lesions who are predisposed to endocarditis undergoing laparoscopy may be warranted.

The diagnostic value of laparoscopy --a perspective study.

Recently, as a result of the introduction of the ingenious method of percutaneous biopsy of the liver according to Menghini, the improvements made in biochemical diagnostics, the introduction of scintigraphy and sonography as well as computer tomography, competing methods have gained ground, raising the question to what extent the scope of indications for laparoscopy is thereby narrowed down. We, ourselves, have now had our own experience with around 19,500 laparoscopies. We thereby experienced 2 deaths as a result of bleeding from abdominal varices. This is still below the risk of collective statistics concerning percutaneous liver biopsy. One must, nevertheless, consider whether by extending our diagnostic possibilities the indications for laparoscopy can continue to be applied as they have been in the past.

Evaluation of a flexible endoscope for laparoscopy.

Thirty patients underwent diagnostic laparoscopy using an unmodified Olympus GIF-P2 fiberendoscope. Both feasibility and safety of the fiberoptic instrument were evaluated. Compared to conventional laparoscopy, a greater area of the peritoneal cavity was visualized, and biopsies and photographs were successfully obtained. There were neither mechanical nor infectious complications. As has occurred in other areas of endoscopy, use a flexible instrument for laparoscopy appears to offer advantages over conventional rigid laparoscopes.

Surgical management of benign cystic teratoma. Laparoscopy vs. laparotomy.

OBJECTIVE: To compare laparoscopy to laparotomy for the surgical treatment of benign cystic teratomas. STUDY DESIGN: This was a retrospective, case series comparison of 20 patients who had surgery at Rochester General Hospital from June 1991 to January 1993 for benign cystic teratomas. Statistical comparisons were made by Student's t test or chi 2 analysis. RESULTS: Eight patients had surgery via laparoscopy and 12 via laparotomy. Laparoscopic oophorectomy and cystectomy resulted in significantly shorter hospital stays and decreased hospital costs, but the surgery time was significantly increased. The patients' fertility status influenced the choice of conservative cystectomy or nonconservative oophorectomy as the surgical procedure. There were no serious complications in any patients, including those with laparoscopic cystectomies and intraperitoneal spill. CONCLUSION: Oophorectomy and ovarian cystectomy via operative laparoscopy appear to be reasonable options for the surgical treatment of benign cystic teratoma.

Laparoscopy and laparoscopic ultrasonography in staging of carcinoma of the esophagus and gastric cardia.

BACKGROUND: The objective of this prospective study was to assess the contribution of laparoscopy combined with laparoscopic ultrasonography (LLU) in the preoperative staging of patients with carcinoma of the esophagus and cardia. STUDY DESIGN: Preoperative LLU was performed in 56 patients who were selected for curative resection of carcinoma of the esophagus (n = 38) or gastric cardia with involvement of the distal esophagus (n = 18) after routine preoperative workup. During LLU, the peritoneal cavity was scrutinized for metastatic disease, and ultrasonography of the liver and celiac axis was performed. In all patients without histologically proven metastases, laparotomy was then performed. RESULTS: The morbidity rate of the procedure was 3.5 percent (two superficial wound infections). In three (5 percent) of the 56 patients, laparotomy was excluded by the presence of intra-abdominal metastases. In three other patients, laparotomy was necessary to confirm the suspected hepatic or peritoneal metastases, or both, because histologic proof was not obtained at laparoscopy. In one patient, LLU failed to detect a small hepatic metastasis in segment VII. The preoperative stage was altered by laparoscopy in nine (17 percent) patients (M1 in six, T4 in three). Laparotomy was avoided in two (11 percent) and the preoperative stage changed in seven patients (41 percent), all of whom had carcinoma of the gastric cardia, as occurred in one (3 percent) and two (6 percent) patients with middle and distal carcinoma of the esophagus, respectively. CONCLUSIONS: Preoperative staging by LLU is of little value in patients with carcinoma of the middle and lower esophagus. The probable role of LLU in the staging of patients with carcinomas of the gastric cardia remains to be confirmed in larger series.

[The role of laparoscopy in the diagnosis of primary peritoneal mesothelioma].

In this study we demonstrate the usefulness of laparoscopy on the diagnosis of some unusual causes of ascites, such as primary mesothelioma, usually overlooked by other diagnostic modalities, like ultrasound, computed tomography and cytology of the ascitic fluid. We describe three cases of primary peritoneal mesothelioma among 27 patients with exudative ascites submitted to laparoscopy at our institution during the past two years. The final diagnosis inaccessible to the conventional diagnostic modalities, was reached only by laparoscopy.
