[Retained foreign bodies from the surgical point of view].

The number of foreign bodies remaining in the patient after a surgical procedure is presumably higher than mentioned in the literature. According to US insurance statistics, the incidence amounts to 1 in 1,500 surgical procedures. As a basic principle--also from the legal aspect--it is necessary to determine whether a foreign body was left in situ accidentally (i.e. due to a material fault) or if it was simply forgotten. In 70% of cases, fabric items (e.g. swabs etc.) are left behind, while around 30% are metal objects. A particularly high risk is seen in emergency settings, in unexpected changes in the surgical procedure, or for patients with a high body mass index. The outcome for the patient differs depending on the nature of the object left behind and the individual patient's situation. Usually, metal items cause more acute clinical symptoms at an earlier time after the operation. Fabric items tend to induce, in the absence of primary contamination, a chronic progression of symptoms over several years. Reoperation has a high mortality (between 11% and 35%). Precautions in terms of risk management have to be established and need to be strictly respected, especially in high risk settings. Visually or acoustically controlled monitoring before wound-closure are recommended to eliminate "human error" as thoroughly as possible.

[Importance of rectal extirpation for the therapy concept of low rectal cancers].

INTRODUCTION: The main objective of surgery of rectal carcinomas is to avoid a permanent colostomy by sphincter-sparing surgical procedures. A variety of different abdominoperineal resection rates is described in the literature. MATERIAL/METHOD: The study was performed in 2000 within the framework of a multicentric study including 282 hospitals. The purpose of the study was to document the quality of diagnosis and therapy for colorectal carcinomas.A total of 9477 patients were included in this study: 3402 suffering from a rectal carcinoma and 6075 suffering from a colon carcinoma. RESULTS: A total of 866 abdominoperineal resections was performed. This corresponds to an abdominoperineal resection rate of 27.4%. In 30.4% of all men and in 23.0% of all women an abdominoperineal resection was performed. Of all tumor patients who underwent abdominoperineal resection, 8.3% had a pT4 carcinoma and 57.5% a pT3 carcinoma. Adapted to the localization of the tumor in the rectum, i.e., the distance of the aboral tumor margin to the anal verge, the following abdominoperineal resection rates were found: <4 cm from the anal verge 84.6%, 4-7.9 cm 43.9%, 8-11.9 cm 5.8%, and 12-16 cm 0.5%.Intraoperative complications occurred in 11.8%, specific postoperative complications in 33.1%, and general postoperative complications in 27.4% of the patients. The postoperative lethality was 2.8%. The mean postoperative hospital stay was 21.7 days. Logistic regression identified the body mass index, gender, the distance of the carcinoma from the anal verge, and the T category as independent factors influencing the abdominoperineal resection rate. DISCUSSION: Despite an overall decrease in use, abdominoperineal resection will continue to play an important role for the surgical treatment of low rectal cancers in routine clinical practice in Germany. It will remain an individual decision for each patient whether the tumor and the patient allow sphincter preservation or whether abdominoperineal resection seems to be necessary. According to the results of the present study,a general definition of an abdominoperineal resection rate in an unselected group of patients should be viewed critically.

[Surgical therapy of inflammatory bowel diseases: ulcerative colitis--diverticulitis. Surgical choices in diverticulitis--conventional or laparoscopic surgery?].

There are no prospective randomized studies available to decide which surgical approach should be superior to treat sigmoid diverticulosis. Analysis of clinical studies evaluating laparoscopic or conventional surgery are presenting results as follows: for elective surgery morbidity ranges between 12-20% and mortality rates between 0-2% indicating comparable complication rates. For emergency operations only data from open surgery are available, with morbidity of 33-57% and mortality rates of 7-16%. Advantages of conventional approach are availability, reliability of the surgical technique and there is no patient selection required. Laparoscopic access may offer superior patients comfort and reduce cost, length of hospital stay and resocialisation. It remains to be proven, which approach may be the option of choice in the future, while this surgical technique is still developing.

[Surgical therapy of morbid obesity using an adjustable gastric band. Report of experiences over 2 1/2 years with 71 patients].

BACKGROUND: At present, long-term results after conservative treatment of morbid obesity (body mass index > 40) are not satisfying, given a relapse rate > 95%. In comparison, surgical treatment is about 10 times more efficient and, thus, more cost-effective. SURGICAL TECHNIQUES: Currently performed surgical interventions to induce weight loss are dominated by two major surgical procedures: (1) Mason's vertical gastroplasty, and (2) the insertion of an adjustable gastric band, developed by Kuzmak in 1983. Essential advantages of gastric banding include the possibility of laparoscopic performance and complete reversibility of the operation. After removal of the gastric band, stomach and upper intestine are left in their anatomic and functional integrity. PATIENTS AND RESULTS: During a 30-month period, we implanted the adjustable gastric band in 71 patients (65 female and six male patients). All procedures were performed laparoscopically. In none of the cases did intraoperative complications occur. Postoperatively 1.4% of the patients developed a slippage of the gastric band, 2.1% had complications concerning the subcutaneously placed port, and, eventually, the gastric band had to be removed in 1.4%.

[Laparoscopic emergency surgery in perforated gastroduodenal ulcers].

The value of laparoscopic treatment of perforated gastroduodenal ulcers remains to be determined. To evaluate this modality the results of laparoscopic treatment of 18 patients with perforated gastroduodenal ulcers were compared with 28 patients who were operated by open access. Patients operated on conventionally had a mean ASA score of 2.9 compared to 1.8 in the laparoscopic group (p = 0.0009). Operative time revealed no difference between both groups, no patient had to be converted. Morbidity and mortality was 16.7% (3/18) and 0% in the laparoscopic group compared to 10.7% (3/28) and 35.7% (10/28) in the open group (p = 0.41 and p = 0.19). The mean postoperative hospital stay was 9.4 compared to 15.3 days (p = 0.15). The laparoscopic treatment of perforated gastrointestinal ulcers is an effective method, which can be used in suited patients with a low morbidity and mortality.

Tension fecopneumothorax due to colonic perforation in a diaphragmatic hernia.

A traumatic diaphragmatic hernia is a well-known complication following blunt abdominal or penetrating thoracic trauma. Although the majority of cases are diagnosed immediately, some patients may present later with a diaphragmatic hernia. A tension fecopneumothorax, however, is a rarity. We report on a patient who, 2 years after being treated for a stab wound to the chest, presented with an acute tension fecopneumothorax caused by the incarceration of the large bowel in the thoracic cavity after an intrathoracic perforation. The etiology and management of this condition are discussed.

Laparoscopic cholecystectomy for a metastasis of a malignant melanoma in the gallbladder.

In a 25-year-old woman who was operated for superficial spreading malignant melanoma two years ago a slowly growing tumor in the gallbladder was detected sonographically. Since further screening for metastatic disease was negative the gallbladder was removed laparoscopically. To our knowledge this is the first laparoscopic cholecystectomy for a metastasis of a malignant melanoma in the gallbladder.

[Bleeding peptic ulcers--concept for acute therapy].

Acute ulcer bleeding still is a life-threatening event. The therapeutic goal is to establish intensity, activity and location of the bleeding and to assess primary hemostasis by consequent endoscopic therapy, also preventing recurrence significantly. With the injection method, primary hemostasis accounts for over 90% success. Also recurrent bleeding can be stopped to the same extent. Endoscopic doppler allows a qualitative and quantitative registration of potentially dangerous vessels on the ulcer base. Drug therapy does serve for the acute treatment to a lesser extent; it is more valid for the initiation of the conservative ulcer therapy. Surgical interventions therefore confined to risk patients in whom a primary hemostasis failed or the ulcer is located in a dangerous site, for instance in the back wall of the duodenal bulb.

Complications after laparoscopic and conventional cholecystectomy: a comparative study.

The growing popularity of laparoscopic cholecystectomy (LC) has made extensive series comparing laparoscopic and conventional cholecystectomy in a prospective, randomized way nearly impossible. To evaluate LC we compared retrospectively 800 laparoscopic with 748 conventional cholecystectomies (CC). Of the 800 LC, 10 (1.2%) were converted to laparotomy. 6 conversions were related to aberrant anatomical features or features making dissection very difficult, 4 conversions were due to complications. There were 5 (0.6%) intraoperative complications during LC and 4 (0.5%) during CC. Postoperative morbidity was 2.1% (n = 17) after LC and 3.7% (n = 28) after CC. Particularly the incidence of wound problems was only 0.5% (n = 4) after LC while it was 1.3% (n = 10) after CC. Overall morbidity was 2.7% (n = 22) for LC and 4.2% (n = 32) for CC. Mortality rate after CC was 0.4% (n = 3), there were no deaths after LC. Common bile duct-injury rate was 0.2% (n = 2) for both groups. Complication rates after LC have been rapidly decreasing with growing experience. Laparoscopic cholecystectomy can safely be performed by appropriately trained surgeons in more than 90% of patients suffering from gallbladder disease. The low morbidity and mortality together with the significant advantages to patient recovery makes laparoscopic cholecystectomy the treatment of choice for symptomatic cholecystolithiasis.

[Mucinous cystadenomas and cystadenocarcinomas of the pancreas--the pancreaticoscopy as a new device for endoscopic and histological diagnosis].

Recent advances in diagnostic imaging procedures offer the opportunity for detection of rare cystic neoplasms of the pancreas. Cystadenomas of the pancreas have been reported to represent 10% of cystic pancreatic lesions. Serous microcystic cystadenoma, megacystic mucinous and duct-ectatic mucinous cystadenoma were distinguished. While the serous cystadenoma is benign, in general the megacystic and the duct-ectatic mucinous cystadenoma have a significant malignant potential. With pancreatoscopy, a rather new endoscopic technique, five cases of mucinous megacystic cystadenoma were diagnosed preoperatively by macroscopic and microscopic means. In one case, development of malignant neoplasm was diagnosed, one patient did not undergo surgery because of her age. Three patients were operated (total pancreatectomy in one case, duodeno-hemipancreatectomy in two cases) and are without any further signs of recurrence and free of symptoms in a one year to four year clinical follow-up.

[Laparoscopic side-to-side gastrojejunostomy].

Development of laparoscopic stapling devices and growing experience with the new method made resective and reconstructive operations on the digestive system accessible to laparoscopy. After extensively testing the method on pigs, we now report on laparoscopic gastro-jejunostomies performed in two patients for gastric stenosis due to inoperable carcinoma of the pancreas. The technique is described. It requires expensive instruments and a very skilled surgeon. While being a safe procedure in the hands of a well-trained surgeon, it presents a high degree of difficulty. Therefore, in order to avoid complications, it should not be advised for a large scale application before results of a greater number of cases can be presented.

[Laparoscopic sigmoid resection].

Laparoscopic appendectomy and cholecystectomy have become routine operations in many hospitals by now. The high acceptance among patients and surgeons together with the development of performing laparoscopic instruments made the laparoscopic approach of colon resections possible. The technique of laparoscopic resection of the sigmoid colon is described. By a surgeon possessing experience in laparoscopic surgery, it can be done without problems. The advantage for the patient lies in less postoperative pain and a shorter hospital stay, but the method still needs to be perfectionated and tested before being advised for a large scale application.
