[Perioperative nutritional therapy and its relevance for postoperative outcome].

The clinical effect of perioperative nutrition was analyzed from 28 controlled clinical trials. Preoperative nutritional support is indicated only in patients with high-grade malnutrition and can reduce the postoperative morbidity and mortality in these patients. If the nutritional status is normal preoperatively, artificial nutrition may influence the postoperative outcome negatively. A clinical benefit from postoperative nutritional support has been proven only in patients not able to eat an adequate oral diet within 1 week. In 20% of these case a cardiopulmonary complication was observed during total parenteral nutrition. The infusion of D5W is sufficient in the majority of surgical patients even after major procedures.

Laparoscopic Billroth-II gastrectomy.

Although the use of laparoscopic techniques in gastric surgery had become a focus in upper gastrointestinal surgery, standardized procedures have not yet been developed. The purpose of the study was to develop a standardized technique for laparoscopic Billroth-II resection in a cadaver model. End points were intraoperative complications and patency of the gastro jejunostomy. Laparoscopic partial stomach resection was performed in seven cadavers. The specimen was removed through an enlarged trocar incision. The first part of the jejunum was temporarily taken out through the same incision and a side-to-side jejuno-jejunostomy created. The gastrojejunostomy was stapled intracorporally. After surgery, all cadavers underwent autopsy. No lesions of intraabdominal organs were found, and the gastrojejunostomy was patent with correct stapling. No major intraoperative complications were recorded. Using the described technique, a laparoscopic Billroth-II operation can safely be accomplished. The technique has been successfully performed in three patients in the last month.

[Laparoscopic gastrectomy. A case report].

Although laparoscopic techniques in gastric surgery have become an important part of upper gastrointestinal surgery, they are mainly utilized for organ preserving procedures. A standardized technique for laparoscopic gastrectomy has not yet been described in detail. The purpose of this study was to develop a standardized technique for laparoscopic gastrectomy with reconstruction by a stapled termino-lateral esophago-je-junostomy and Roux-en-Y-anastomosis in a cadaver model. The resected stomach was removed through an enlarged trocar incision. The described technique has been successfully performed in one patient with early gastric cancer.

["Open" versus laparoscopic appendectomy].

A total of 701 patients operated on with the suspected diagnosis of acute appendicitis were included in a prospective study. Three hundred and nine patients were treated conventionally and 387 laparoscopically. In 14 patients the operation had to be converted. Operating time was 44 min in the laparoscopic group and 54 min in the conventional group. The advantages of the laparoscopic technique were better visualisation of the abdominal cavity, fewer complications, shorter hospital stay and better cosmetic result. Complications occurred in 2.9% of the patients in the laparoscopic group and in 13.6% of the patients in the conventional group. All complications following laparoscopic procedures could be treated laparoscopically.

[Laparoscopic surgery of a thoracic stomach].

We report the case of a 54-year-old patient with up-side-down-stomach with recurrent gastric bleeding. Reposition of the stomach, closure of the diaphragmatic opening with interrupted silk sutures, fundophrenicopexy and corpopexy to the anterior abdominal wall was done laparoscopically. Because the patient presented no reflux symptoms, but hypomotility of the oesophagus, no fundoplication was done. To prevent recurrence of the hernia a polypropylene mesh was fixed over the hiatus.

[100 years after Billroth... Laparoscopic Billroth I and Billroth II distal stomach resection].

In the period October 1993-February 1994, we performed three distal stomach resection operations laparoscopically (two Billroth-II anastomoses, one Billroth-I anastomosis combined with truncal vagotomy). The first patient, 83-year old, presented a stenosing, bleeding, prepyloric, malignant Non-Hodgkin lymphoma. The second patient, 84-year old, presented an ulcerated, non-malignant leiomyoblastoma of the antrum. Due to the histological type of the tumors a radical lymphadenectomy was not performed. The partially resected stomach (two thirds) was removed in a lap sac through a 3.5 cm infraumbilical incision. The third patient presented a persisting, prepyloric ulcer combined with an almost complete stenosis of the pylorus. In all three cases, it was possible to follow the principles of conventional open surgery. The anastomoses were all stapled intracorporally, no intraabdominal complications occurred. However, the first patient died on the 21st postoperative day from cardiopulmonary failure, the remaining two patients were discharged on day 11/day 12 postoperatively.

[Technique in laparoscopic cholecystectomy. Experiences and results in 200 interventions].

This study provides the data and experience of 200 laparoscopic cholecystectomies. The stenosis of the bile duct caused by a ligature in one patient and aberration of the bile duct in two patients led to remarkable intraoperative complications. The average operation time as well as postoperative recovery periods emphasize the importance of laparoscopic cholecystectomy as a relevant alternative to the traditional approach.
