Comparison of laparoscopic and open staging in Hodgkin disease.

BACKGROUND: Staging laparotomy provides useful information for management of Hodgkin disease but has fallen into disfavor because procedure-related morbidity exceeds that of new chemotherapeutic regimens. OBJECTIVE: To determine the feasibility, effectiveness, and safety of laparoscopic staging for Hodgkin disease compared with those of open staging. PATIENTS: Fifty-five patients with Hodgkin disease of cell types including nodular sclerosis in 43 (78%), mixed cellularity in 9 (16%), and lymphocyte predominance in 3 (5%). STUDY DESIGN: Concurrent evaluation of laparoscopic staging (n = 15) and retrospective review of open staging (n = 40). INTERVENTIONS: Laparoscopic and open techniques of surgical staging for Hodgkin disease, including splenectomy, liver biopsies, and lymph node sampling. MAIN OUTCOME MEASURES: Operative time, duration of postoperative ileus and of postoperative hospitalization, morbidity, number of lymph nodes retrieved, alteration in pathologic stage, recurrence, and survival. RESULTS: For laparoscopic staging vs open staging groups, mean operative time was 202 vs 144 minutes (P=.001); mean postoperative ileus was 1.9 vs 3.2 days (P<.001); mean postoperative hospitalization was 4.4 vs 6.7 days (P<.001); complications occurred in 3 patients (20%) vs 11 patients (28%) (P=.57); and mean number of lymph nodes retrieved was 8.5 vs 4.6 (P=.05). In the laparoscopic staging group, 2 cases (13%) were upstaged and 2 cases (13%) were downstaged. In the open staging group, 6 cases (15%) were upstaged and 3 cases (7.5%) were downstaged. Follow-up data were available for all patients in the laparoscopic staging group, at a mean of 23.5 months postoperatively. All were alive, none had recurrent disease below the diaphragm, and 2 (13%) had residual mediastinal disease. Follow-up data were available for 31 patients (78%) in the open staging group at a mean of 52.5 months postoperatively. All were alive, 27 (87%) were disease free, 3 (10%) had had relapses above the diaphragm, and 1 (3%) had residual mediastinal disease. CONCLUSIONS: Compared with open staging, laparoscopic staging of Hodgkin disease is oncologically equivalent and functionally superior. These data should encourage reappraisal of the role of operative staging in the management of Hodgkin disease.

Laparoscopic versus open splenectomy in the management of splenomegaly: our preliminary experience.

BACKGROUND: Laparoscopic splenectomy for normal-sized spleens has several advantages compared with laparotomy. Only a few cases of splenomegaly done by laparoscopy are reported in the literature. The purpose of this study is to show that laparoscopy for splenomegaly is feasible and has several advantages over the open operation. METHODS: We performed retrospective chart review of 8 cases of splenomegaly managed by laparoscopy (group 1), 15 cases of open splenomegaly (group 2), and 27 cases of laparoscopic splenectomy for normal-sized spleens (group 3). Comparison has been done between groups 1 and 2 and groups 1 and 3 in terms of operative time, intraoperative estimated blood loss, need for blood transfusion, postoperative ileus, postoperative stay, and mortality and morbidity rates. RESULTS: Patients in group 1 required longer operative time and significantly less intraoperative blood transfusion compared with group 2. The postoperative course was less complicated and shorter in group 1 than in group 2. Operative time was longer in group 1 compared with group 3. No significant differences in terms of postoperative course have been found between groups 1 and 3. CONCLUSIONS: Laparoscopy for splenomegaly is a feasible, effective, and safe technique for experienced laparoscopic surgeons. This approach seems to have several advantages over the open operation. Prospective, randomized trials would be required for a proper quantitative evaluation.

[Laparoscopic versus laparotomic adrenalectomy: preliminary experiences].

The authors report their experience about laparoscopic surgery in the treatment of adrenal tumours. Three laparoscopic right adrenalectomies were performed. From a comparison with five open adrenalectomies, microinvasive surgery is more advantageous than traditional management: recovery is earlier, incisions are smaller, post-operative discomfort is less, physiologic functions recover in a short time, return to full professional activity in one week.

[Surgical treatment of liver metastases of breast carcinoma. Our experience].

The authors report their experience in the surgical treatment of breast cancer liver metastases. Although with a restricted number of cases (4 patients), the short-term results are satisfactory; this is in agreement with the literature. The survival of those patients treated with a loco-regional approach to metastases (chemotherapy and surgery), is longer than one obtained using systemic chemotherapy. This is still an open question requiring further experience.

Laparoscopic splenectomy in the management of hematological diseases. Surgical technique and outcome of 17 patients.

After being successfully applied to other intraabdominal organs, the laparoscopic approach has been applied to the spleen since 1991. The experience with 17 cases of laparoscopic splenectomy performed due to immune thrombocytopenia purpura (10 instances), hereditary spherocytosis (2 cases), and Hodgkin's disease where the staging was done according to Standford (5 cases), have been reported. With the patient in anti-Trendelenburg position, and the surgeon between the patient's legs, four or five trocars are introduced into the upper abdominal quadrants and the spleen hilum is isolated. Hilar vessels are dissected and ligated with a surgical stapler. A plastic bag is introduced into the abdomen cavity and the spleen is slipped inside; it is then extracted through an umbilical incision after morcellation. Advantages of the open operation include a decrease in postoperative pain, a decrease in pulmonary sequelae, a reduced incidence of subphnic abscesses, and cosmetic advantages. The decrease of postoperative sequelae reduces hospitalization and costs, which are higher for the operation itself (materials and staff's training).

Preemptive analgesia: intraperitoneal local anesthetic in laparoscopic cholecystectomy. A randomized, double-blind, placebo-controlled study.

BACKGROUND: A controversy exists over the effectiveness and clinical value of preemptive analgesia. Additional studies are needed to define the optimum intensity, duration, and timing of analgesia relative to incision and surgery. METHODS: One hundred twenty patients undergoing laparoscopic cholecystectomy under general anesthesia plus topical peritoneal local anesthetic or saline were studied. Local anesthetic (0.5% bupivacaine with epinephrine) or placebo solutions were given as follows: immediately after the creation of a pneumoperitoneum (blocking before surgery), and at the end of the operation (blocking after surgery). Patients were randomly assigned to one of four groups of 30 patients each. Group A (placebo) received 20 ml 0.9% saline both before and after surgery, group B received 20 ml 0.9% saline before surgery and 20 ml local anesthetic after surgery, group C received 20 ml local anesthetic both before and after surgery, group P received 20 ml local anesthetic before and 20 ml 0.9% saline after surgery. Pain was assessed using a visual analog scale and a verbal rating scale at 0, 4, 8, 12, and 24 h after surgery. Metabolic endocrine responses (blood glucose and cortisol concentrations) and analgesic requirements also were investigated. RESULTS: Pain intensity (visual analog and verbal rating scales) and analgesic requirements were significantly less in the group receiving bupivacaine after surgery compared to placebo. However, in the groups receiving bupivacaine before surgery, both pain intensity and analgesic consumption were less than in the group receiving bupivacaine only after surgery. Blood glucose and cortisol concentrations 3 h after surgery were significantly less in groups receiving bupivacaine before surgery. CONCLUSIONS: The results indicate that intraperitoneal local anesthetic blockade administered before or after surgery preempts postoperative pain relative to an untreated placebo-control condition. However, the timing of administration is also important in that postoperative pain intensity and analgesic consumption are both lower among patients treated with local anesthetic before versus after surgery.

[Solid papillary tumor of the pancreas. A clinical case].

The solid papillary tumor of the pancreas is a relative rare neoplasm that often is unknown because of its diagnostic difficulties. It is frequent in young women. It has no typical clinical signs, sometimes produces abdominal mass, sometimes is found casually during investigations for other diseases. Instead the prognosis of this tumor is more typical: long-term survival is good. The natural history of the solid papillary is the same as neoplasm with a low malignancy potential. For this reason, it's important to make up a differential diagnosis between it and the other pancreatic tumors. Unlike the other malignancies, surgical conservative therapy is enough without making great demolitions of the pancreas. Lumpectomy gives a complete cure, decreasing surgical risk and dangerous functional complications. In the present paper, a case of solid papillary tumour of the pancreas is reported. It was diagnosed in a young woman and treated with simple lumpectomy. She is alive and disease free.

[Hemoperitoneum caused by lesions to the appendix epiploica. An unusual complication of colonoscopy].

A rare case of hemoperitoneum in a young man who performed a diagnostic colonoscopy is reported. The rupture of an epiploic appendix among rectum and colon sigma caused massive bleeding into the peritoneum cavity followed by haemorrhagic shock. Diagnostic and therapeutic colonoscopy has a low rate of morbility; perforation and bleeding are the most common events; hemoperitoneum following colonscopy is usually due to spleen rupture. Among other complications, ileal and cecal volvolus, incarceration of hernias and subcutaneous emphysema are reported.

[Arterio-portal fistula. Report of a case and review of the literature].

Mesenteric arteriovenous fistulas or arterioportal fistulas (APF) are rare and mostly secondary to penetrating abdominal wounds. A rare case of APF presenting 2 years later a blunt abdominal trauma has been reported. On the basis of a review of the literature (65 cases) the etiology, clinical findings, diagnostical aspects and the results of conservative and surgical treatment have been analyzed.

The effects of intraperitoneal local anesthetic on analgesic requirements and endocrine response after laparoscopic cholecystectomy: a randomized double-blind controlled study.

This randomized double-blind placebo-controlled study was designed to evaluate the effects on postoperative pain of the local anesthetic, 0.5% bupivacaine with epinephrine, sprayed hepatodiaphragmatically under the surgeon's direct view during laparoscopic cholecystectomy. Metabolic endocrine responses to surgery (glucose and cortisol) and nonsteroidal anti-inflammatory drug requirements were investigated, as well as the presence of nausea, vomiting, and sweating. Local anesthetics or placebo solutions were given as follows. Immediately following the creation of a pneumoperitoneum, surgeons sprayed the first 20 mL of solution (S1), and an additional 20 mL of solution (S2) was sprayed at the end of the operation. Patients were classified into three groups (14 patients per group). Group A received 20 mL of saline during both S1 and S2, group B received 20 mL of saline during S1 and 20 mL of bupivacaine during S2, and group C received 20 mL of bupivacaine during both S1 and S2. The degree of postoperative pain was assessed using the visual analogue scale (VAS) and the verbal rating scale (VRS) on arrival in the recovery room and subsequently at time intervals of 4 h, 8 h, 12 h, and 24 h. The results of this study indicate a significant decrease of postoperative pain in patients treated with local anesthetic. VAS and VRS pain scores, as well as respiratory rate and analgesic requirements, were significantly lower in group C. The postoperative plasma cortisol level in group C was significantly lower than in groups A and B.

[Treatment with immunomodulating drugs of patients with operated cancer. Long-term results].

The authors produce a new course of study in order to verify the efficacy of immunomodulatory treatment in cancer-operated patients. In the General Surgical Clinic and Surgical Therapy Institute of University of Ferrara, from July '86 to June '92, 582 cancer-operated patients were treated by immunomodulatory drugs, making use of standard of absolute random. A group (100 patients) was subjected to peroperative anticontagious immunoprophylaxis; B group (482 patients) to postoperative cyclic immunomodulation; in this last group, were codified C group (166 patients) and D group (63 patients), controlled in follow-up, making use of 3 parameters: survival, clinical-oncological restage, performance status. The results obtained confirm the efficacy of the proposed immunomodulatory treatment: a reduction of incidence both early infections and late infections, an increase of survival, falls in clinical-oncological stage to less advanced levels and, above all, an improvement of performance status.
