Laparoscopic Nissen fundoplication: detailed analysis of 132 patients.

With the world-wide use of laparoscopy, new applications have been found, particularly in the field of esophageal and gastric surgery. From January 1991 through April 1992, 132 patients underwent laparoscopic Nissen fundoplication. The indication for laparoscopic intervention was symptomatic gastroesophageal reflux disease (GERD) not responding to medical treatment. The preoperative assessment included esophagogastroscopy, barium meal, esophageal manometry, and, in selected cases, 24 h pH studies. There was no operative-related mortality. The overall morbidity was 7.5%. Ninety-eight patients were seen 3 months after surgery and evaluated for control of reflux symptoms. One patient complained of mild recurrence of reflux symptoms; however, endoscopic examination revealed no evidence of recurrent esophagitis. Three complained of occasional dysphagia and two, of mild dysphagia. One individual required reoperation for persistent, severe dysphagia. The excellent results observed so far with this procedure have led us to believe that laparoscopic Nissen fundoplication is the procedure of choice for patients with intractable GERD.

Laparoscopic Nissen fundoplication: preliminary report.

Twelve patients presenting with symptomatic esophagitis associated with hiatal hernia and gastroesophageal reflux underwent operative management under laparoscopic guidance. The antireflux procedure employed was the Nissen fundoplication. The authors completed the operation laparoscopically in nine patients. Postoperatively, patients were evaluated with repeat fiberoptic endoscopy, esophageal manometry, and barium contrast studies. Postoperative results were considered excellent on the basis of these studies and complete control of symptoms. The mortality rate was 0%. The only major operative complication was a pneumonia that occurred in one patient. At 1 month follow-up, six patients were totally asymptomatic. The authors conclude that laparoscopic treatment of gastroesophageal reflux associated with a hiatal hernia is feasible by a procedure that has already proven its value during open surgery.

[Tolerance of adjuvant treatment combining postoperative intraportal chemotherapy and a systemic treatment based on 5-fluorouracil in colorectal carcinoma with a histologically poor prognosis].

From April 89 to October 90, 41 patients operated for a Dukes B or C colorectal cancer were randomized to receive 6 courses of adjuvant treatment with (A) 5-FU alone (440 mg/m2 IV bolus 5/21 days) or (B) folinic acid (200 mg/m2 IV bolus 5/21 days) preceding 5-FU (370 mg/m2 in short infusion 5/21 days). Ten patients received also one course of immediate post-operative continuous portal infusion (5-FU 500 mg/m2/day x 7 followed by a 2 hours infusion of mitomycin C 10 mg/m2). The portal treatment was well tolerated (1 case of GI tract disturbances, 1 catheter obstruction). The toxicity of adjuvant systemic treatment was evaluated on 232 courses (125 A, 107 B). Hematologic and skin toxicities, alopecia and nausea-vomiting were mild. The limiting toxicities (expressed as percentages of courses) were stomatitis (grades 2-3: 11.4% A; 22.6% B) and diarrhea (grades 3-4: 7.3% A; 14.2% B; one toxic death was to deplore in arm B from a grade 4 diarrhea). The pilot study has demonstrated the feasibility of the adjuvant treatment proposed; a multicentric randomized trial (expected accrual: 800 patients) has therefore been activated on 11.01.90; all patients will also receive levamisole while radio-therapy will be mandatory for rectal cancer.

[Cholecystectomy using celioscopy: analysis of 368 operations].

The management of calculous disease of the biliary tract has undergone significant changes during the past decade. Yet, the only radical method of treatment remains cholecystectomy. The surgical option has been improved by the development of laparoscopic cholecystectomy. From February 1990 to February 1991, we performed 368 laparoscopic cholecystectomies, with no mortality and a morbidity rate of 3.8%. There were 283 women and 85 men, with a mean age of 56.2 years (range 18 to 92 years). Two patients were asymptomatic but presented with a growing gallbladder polyp. All the other patients were symptomatic: biliary colic (63.8%), dyspepsia (18.6%), or acute cholecystitis (17.6%); 36 patients had an history of stone migration to the main biliary tract. Mean operating time was 58.3 minutes (22 to 180 minutes) and mean postoperative stay was 3.4 days. There were four systemic complications and 10 local technically related complications: two have been controlled by a laparoscopic approach (one hemorrhage and one biliary leak), one by laparotomy (bile duct injury). The other 7 local complications resolved spontaneously (4 biliary fistulas) or by percutaneous punction (3 subphrenic abscesses). Twenty-six patients (7%) required conversion to open cholecystectomy because of technical difficulties with the dissection or main biliary tract stones. We conclude that laparoscopic cholecystectomy is a safe and effective procedure.

Levamisole adds granulocyte toxicity to 5FU-based chemotherapies in adjuvant treatment of Dukes B-C colorectal cancer. A preliminary report.

41 patients (pilot study-I) and 50 patients (multicenter study II) were randomized to receive as systemic chemotherapy for 6 courses with 5 FU alone (A) [440 (I)-450 (II) mg/m2 IV bolus, 5/21 days] or folinic acid followed by 5 FU (B) (respectively 200 and 370 mg/m2 IV bolus, 5/21 days). In the multicenter trial, oral levamisole at the dose of 150 mg/day (3/14 days) was added to chemotherapy for one year. Ten patients in study I and 19 patients in study II also received a post-operative course of intra-portal chemotherapy. Toxicity was evaluated respectively on 232 (I) and 276 (II) courses. Clinical limiting toxicities were stomatitis and diarrhea. In protocol II, a significant enhancement of grades 3-4 granulocyte toxicity was seen (17.3% of courses in II vs only 3.4% in I; p < 0.001). This was especially recorded in the group treated with 5-FU alone (26% of courses in A vs 11% in B; p < 0.001). Levamisole was therefore stopped in 12 cases (10 cases in A; 2 cases in B).

Hepatic resections after chronotherapy: surgical aspects.

Hepatic resection has always been recommended for the treatment of metastatic disease in selected patients. Surgeons have had modified their approach and timing of surgery since the introduction of chemotherapy. The authors report their experiences since the introduction of chronochemotherapy. From 1990 up to 1994, 9 hepatic resections were performed for metastatic colorectal carcinoma. During the same period, 11 arterial accesses were implanted for diffused hepatic disease. Of the 9 resected patients, 5 are still alive with a mean follow-up of 17.7 months with no signs of recurrent disease.

Results of laparoscopic Nissen fundoplication.

BACKGROUND/AIMS: Laparoscopic surgery for treatment of gastroesophageal reflux disease was first described 5 years ago. The more widespread technique is the Nissen fundoplication with its different modifications. The early results suggest that this operation is equivalent in efficacy to the open antireflux operations. METHODOLOGY: Over a 5 year period, 622 patients underwent laparoscopic fundoplication for gastroesophageal reflux disease. Five hundred and fifty patients underwent Nissen fundoplication. Preoperative, operative and postoperative data were prospectively reviewed. One hundred twenty seven patients were evaluated 1 to 4 years after the operation. RESULTS: Laparoscopic Nissen fundoplication with standard gastric mobilisation and without division of the SGV was performed during the first three years of the laparoscopic approach. Since early 1994, we applied division of the SGV with complete mobilisation of the upper part of the gastric fundus in all the patients. The mean operative time was 86 minutes (range 30-180 minutes). Conversion to open surgery was necessary in 5 patients (0.9%). There was neither incidence of splenic trauma nor esophageal perforation. There was no mortality. Morbidity was 2.3%. Mean hospital stay was 3.1 days (range 1-13 days). Postoperative dysphagia was observed in all the patients and resolved after 2 to 6 weeks in all but 12 patients (2.1%) who were submitted to endoscopic dilatation with success in 9 patients. At a median follow-up period of 2 years (16-44 months), 127 consecutive patients from the initial experience (series 1991-1992) volunteerd for mid term follow-up evaluation. We obtained Visick I and II grading in 92% of the patients. Reoperation for failure has been necessary in 6 patients (1.0%). CONCLUSIONS: The long term results of laparoscopic Nissen fundoplication are not yet available. The incidence of poor long term outcome or recurrence of symptoms cannot be assessed. At present, we feel that, in experienced hands, the laparoscopic operation is as good as the open procedure if all the surgical principles of antireflux surgery are respected. One of our complications is related to the choice of the operative technique and that highlights the absolute necessity of strict preoperative assessment and selection of the patient but also selection of the type of operation, tailored to the patient.
