RESUMO
Objectives: Rectal prolapse is defined as prolapse of all layers of rectal wallout of the anal sphincter. The aim was to (i) describe the extremely rare combination of a rectal prolapse with colon cancer in an older female patient, (ii) comment on management-specific aspects and (iii) derive some generalizing recommendations by means of a scientific case report and based on the case-specific experiences related to the clinical management and current references from the medical literature. Case presentation: A 69-year old female patient with cancer of the sigmoid colon at a manifest rectal prolapse was diagnosed. Literature search (using the data bank of "PubMed") resulted in only six patients (the majority of them were females) with the coincidence of rectal prolapse and rectal or colon cancer have been reported so far. Conclusions: A patient with a manifest rectal prolapse needs always to undergo colonoscopy and - in case of an ulcer - histological investigation of representative biopsies.
RESUMO
INTRODUCTION: Despite the well-documented safety and effectiveness of laparoscopic colorectal surgery in curative intention, the role of conversion and its impact on short- and long-term outcome after resection of a carcinoma are unclear and continue to give rise to controversial discussion. METHODS: Within the framework of a prospective, multicenter observational study (Laparoscopic Colorectal Surgery Study Group), into which a total of 5,863 patients from 69 hospitals were recruited over a period of 10 years, a subgroup of all patients who had undergone curative resection was analyzed with regard to the effects of conversion. RESULTS: Of the 1409 patients who had undergone curative resection for colorectal carcinoma, conversion had to be performed in 80 (5.7%) cases for the most diverse reasons. The duration of surgery (median: 183 vs. 241 minutes; P<.001) was significantly longer in the conversion group. Perioperatively, significant disadvantages were noted in converted patients in terms of intraoperative blood loss (median: 243 vs. 573 mL, P<.001), need for perioperative blood transfusion (10.8% vs. 33.8%; P<.001), and resumption of bowel movement (median: after 3 vs. 4 days; P<.001). With regard to postoperative morbidity, significant disadvantages were observed in converted patients, in particular in terms of specific surgical complications, including a higher rate of anastomotic insufficiency (5.0% vs. 13.8%; P=.003) and a higher reoperation rate (4.9% vs. 15.0%; P=.001). In the long term, conversion was associated with lower overall survival, but not with poorer disease-free survival. CONCLUSION: Significantly higher postoperative morbidity was observed in patients after conversion, in particular in terms of specific surgical complications. In addition, conversion is associated with overall lower survival but not with poorer disease-free survival.

OBJECTIVES: Chylothorax is an infrequent but serious complication after thoracic surgery. Optimal management is still controversial. Surgical re-interventions are associated with significant morbidity and mortality. DESIGN: During a 2-year period, 3 patients developed chylothorax after oesophagectomy. This was treated conservatively, following our departmental protocol. RESULTS: Conservative management (total parenteral nutrition, bowel rest, pleural drainage and octreotide, followed by a low-fat diet) was successful in all 3 cases within a reasonable period of time (14 - 18 days). CONCLUSION; We recommend conservative measures as the first-line treatment for postoperative chylothorax.

INTRODUCTION: Restoration of intestinal continuity following Hartmann procedure is an operation associated with a lengthy stay in hospital, protracted convalescence, and a high morbidity rate. With the aim of using the advantages of minimally invasive surgery, such as rapid mobilization, less postoperative pain, early restoration of bowel function, and a rapid return to a normal diet, and reduced morbidity, the laparoscopic modality was employed. The objective of the present study was to investigate the usefulness of laparoscopic restoration of intestinal continuity following Hartmann procedure. METHOD: A total of 71 patients who, in the period between 1995 and 2005 within the framework of the prospective multicenter study "Laparoscopic Colorectal Surgery Study Group," underwent a laparoscopically assisted restoration of bowel continuity following Hartmann procedure, were investigated. RESULTS: In 62 patients (87%), the laparoscopic procedure was completed as planned, whereas 9 cases had to be converted to open surgery-mostly on account of massive intra-abdominal adhesions. The 39 male (55%) and 32 female (45%) patients had an average body mass index of 25 (range, 19 to 38), a height of 168 cm (range, 150 to 190 cm), and a weight of 72 kg (range, 49 to 103 kg). Mean operating time was 164 min (range, 60 to 410 min) and the intraoperative blood loss 196 mL (range, 10 to 1000 mL). Five patients (7%) received packed red cells. In all, 85.9% of the procedures (n=61) were free of complications. The most common intraoperative complications were injuries to the bowel and problems with the anastomosis (dehiscence, difficult stapling), each occurring in 5.6% of the cases (n=4). Intraoperative lesions to the ureters (0%), the bladder (n=1/1.4%), and blood vessels (n=1/1.4%) played a numerically subordinate role. Purely parenteral nutrition was applied up to the third postoperative day (range, 0 to seventh postoperative day). In those patients who were able to take a liquid meal on the third postoperative day (range, first to eighth postoperative day), enteral nutrition was initiated on the fifth postoperative day (range, second to tenth postoperative day). On average, bowel movements were restored on the fourth postoperative day (range, second to ninth postoperative day). Patients in whom a bladder catheter was placed for the operation had it removed on the third postoperative day (range, first to twelfth postoperative day) and had normal urination thereafter. In Hartmann procedure, patients without such a catheter, normal urination was possible from postoperative day 1 onward (range, 0 to second postoperative day). Postoperative complications included hematomas/abscesses (n=3/4.2%), transit disorders (n=2/2.8%), surgery-requiring ileus (n=2/2.8%), cardiopulmonary complications (n=1/1.4%), and surgery-requiring hemorrhage (n=1/1.4%), with other complications accounting for 4.2% (n=3). The median hospital stay was 11 days (range, 5 to 35 d); the mortality rate was 1.4% (n=1). CONCLUSIONS: Reversal of Hartmann procedure employing the laparoscopic modality is compatible with acceptable morbidity and mortality rates. The elevated conversion rate is a reflection of the fact that the operation is technically demanding.

BACKGROUND: For the management of endoscopically irretrievable polyps, several minimally invasive procedures are currently available as alternatives to conventional laparotomy. However, the high rate of malignant transformation despite initially benign histology continues to be a problem. METHODS: Within the framework of a prospective multicenter observational study, all patients with adenomatous polyps unsuitable for endoscopic removal and with benign histology were investigated. In addition to an analysis of the perioperative course and the definitive histology, the overall and disease-free survival rates of patients with malignant transformation of colorectal adenomas were also calculated. RESULTS: A total of 525 patients (median age 65.3 years; median body mass index 25.6 kg/m(2)) underwent a laparoscopic resection. Conversion to laparotomy became necessary in 17 (3.2%) cases. The perioperative morbidity rate was 20.8%, and malignant transformation occurred in a total of 18.1% of the adenomatous polyps. The median number of lymph nodes removed was 12, and lymph node metastases were seen in a total of 14.8% of the patients (T1--4.8%, T2--19.4%, T3--25%, T4--100%). Estimated 5-year overall and disease-free survival rates were 92.4% and 80.6%, respectively. CONCLUSIONS: For the management of endoscopically unresectable polyps, laparoscopic resection is currently the technique of choice. In addition to the benefits of minimally invasive surgery, in the hands of an experienced surgeon it achieves results comparable with those of open surgery. In view of the high rate of malignant transformation and the absence of unequivocal factors predictive of already present malignant transformation, an oncologically radical operation is essential. In the elderly patient presenting with comorbidities limited resection aiming to minimize surgical trauma in potentially benign disease may be considered. In such a case, however, frozen-section histology is obligatory.

BACKGROUND: Obesity is a modern-day phenomenon that is increasing throughout the world. The aim of the present study was to provide data to establish whether the laparoscopic approach to colorectal surgery in the obese patient represents a risk or, rather, a benefit for the patient. METHOD: The data presented in this paper were obtained within the framework of a prospective multicenter study initiated by the "Laparoscopic Colorectal Surgery Study Group (LCSSG)" and performed on 5,853 recruited patients. The perioperative course was compared between the three groups: nonobese, obesity grade I, and obesity grade II/III. RESULTS: Increasing body mass index correlated with a highly significant increase in the duration of the operation (nonobese 167 min, grade I 182 min, grade II/III 191 min; p < 0.001) and in the conversion rate (nonobese 5.5%, obesity grade I 7.9%, obesity grade II/III 13.1%; p < 0.001). The intraoperative complication rate also showed a tendency to increase (nonobese 5.0%, grade I 6.2%, grade II/III 7.1%; p = 0.219). In contrast, no significant differences were found between the groups with regard to the postoperative complication rate (nonobese 20.7%, grade I 21.0%, grade II/III 20.2%), the reoperation rate (nonobese 4.1%, grade I 3.9%, grade II/III 3.6%), and the postoperative mortality rate (nonobese 1.1%, grade I 1.9%, grade II/III 1.8%). CONCLUSION: Laparoscopic colorectal surgery is clearly more technically demanding in the obese patient. Apart from this, however, it is not associated with any increased risk of postoperative complications, and thus demonstrates that the pathologically overweight patient can benefit to a particular degree from the laparoscopic modality.

BACKGROUND AND AIMS: Colorectal surgery performed in palliative intent is a relatively common intervention. The present study investigates the question whether such interventions are suitable for laparoscopic procedure. PATIENTS AND METHODS: The data presented herein were collected from 4834 patients within the framework of a multicenter study initiated by the "Laparoscopic Colorectal Surgery Study Group (LCSSG)." In a subgroup analysis of 331 operated palliative-intent patients, the short-term outcomes were evaluated and compared with those obtained in patients undergoing surgery for benign indications. RESULTS: Overall, the morbidity and mortality rates were significantly higher in the cancer patients than in patients with a benign indication, with no significant differences between the 2 groups in terms of intraoperative complications, conversion, and reoperation rates. The analysis of the individual complications revealed that the significant differences were due exclusively to the more frequent presence of general medical complications, and thus were unrelated to the laparoscopic procedure. CONCLUSIONS: The laparoscopic approach to the palliation of incurable colorectal carcinomas was associated with comparable results with regard to intraoperative complications, conversion, reoperation rates, and postoperative surgical complications in comparison with surgical procedures for benign indications, with significantly higher morbidity and mortality rates related solely to general-medical complications.

BACKGROUND: Surgery, as well as conservative treatment, in patients with clinically apparent intrathoracic esophageal anastomotic leaks often is associated with poor results and carries a high morbidity and mortality. The successful treatment of esophageal anastomotic insufficiencies and perforations when using covered, self-expanding metallic stents is described. METHODS: The feasibility and the outcome of endoscopic treatment of intrathoracic anastomotic leakages when using silicone-covered self-expanding polyester stents were investigated. Twelve consecutive patients presented with clinically apparent intrathoracic esophageal anastomotic leak caused by resection of an epiphrenic diverticulum (n = 1), esophagectomy for esophageal cancer (n = 9), or gastrectomy for gastric cancer (n = 2), were endoscopically treated in our department. The extent of the dehiscences ranged from about 20% to 70% of the anastomotic circumference. After endoscopic lavage and debridement of the leakage at 2-day intervals (mean duration, 8.6 days), a large-diameter polyester stent (Polyflex; proximal/distal diameters 25/21 mm) was placed to seal the leakage. Simultaneously, the periesophageal mediastinum was drained by chest drains. OBSERVATIONS: All 12 patients were successfully treated endoscopically without the need for reoperation. A complete closure of the leakage was obtained in 11 of 12 patients after stent removal (median time to stent retrieval, 4 weeks, range 2-8 weeks). In one patient, a persistent leak was sealed endoscopically after stent removal by using 3 clips. Distal stent migration was obtained in two patients. CONCLUSIONS: The placement of silicone-covered self-expanding polyester stents seems to be a successful minimally invasive treatment option for clinically apparent intrathoracic esophageal anastomotic leaks.

BACKGROUND: The aim of the present study was to analyze changes regarding the indications for and results of laparoscopic treatment of sigmoid diverticulitis. METHODS: The data were collected within the framework of an ongoing prospective multicenter study carried out by the Lapa roscopic Colorectal Surgery Study Group and were submitted to a statistical subgroup analysis. The institutions participating in the study were divided into three groups by experience (Group I, >100 procedures; Group II, 30-100 procedures; Group III, < 30 procedures). RESULTS: Among the 3,868 recruited patients, sigmoid diverticulitis (n = 1,545, 40 percent) was by far the most common indication for surgery, and sigmoid resection (n = 2,160, 55.9 percent) was by far the most common laparoscopic procedure. A total of 1,353 patients (87.6 percent) had uncomplicated diverticulitis, whereas 192 (12.4 percent) had a complicated form of diverticular disease (Hinchey I-IV, diverticular bleeding, fistula formation). Cases of complicated diverticulitis were significantly more frequently operated on at institutions with greater experience (Group I, 20.8 percent; Group II, 8.7 percent; Group III, 7.9 percent). Despite this fact, these institutions still had better intraoperative complication rates (Group I, 5.0 percent; Group II, 5.8 percent; Group III, 6.9 percent), conversion rates (Group I, 4.4 percent; Group II, 6.7 percent; Group III, 7.7 percent), and postoperative morbidity (Group I, 15.9 percent; Group II, 16.6 percent; Group III, 18.6 percent) and mortality (Group I, 0.2 percent; Group II, 0.5 percent; Group III, 0.4 percent) rates. CONCLUSION: An increase in experience is associated with an expansion of laparoscopic indications to include complicated forms of diverticulitis, with comparable ntraoperative and postoperative complication rates, operating time, and mortality rates.

The enthusiasm for laparoscopic procedures in the field of visceral and colorectal surgery, in particular, has increased. Potential advantages include a reduction in pain as a result of less trauma, improved postoperative immune function, the earlier reestablishment of postoperative intestinal transit, shorter hospitalization, improved cosmesis, and reduced formation of intra-abdominal adhesions. In contrast to treatment for benign conditions, laparoscopic surgery with curative intent for malignancy is still controversial. In particular, compliance with the required criteria of oncologic radicality (extent of lymph node dissection, prevention of intraoperative tumor cell dissemination, assurance of acceptable margins of clearance) and thus, the achievement of long-term results identical with those results obtained after laparotomy, are considerations that have repeatedly been questioned. However, a number of published reports have confirmed that all the criteria for oncologic radicality in colorectal surgery can be met. An additional advantage of laparoscopic abdominoperineal excision is that it avoids a number of general problems associated with laparoscopic colorectal surgery. However, despite this encouraging information, a general recommendation for the use of laparoscopic abdominoperineal excision can be made only when definitive long-term results are available. Against this background, we discuss the questions of oncologic radicality and long-term outcome on the basis of currently available published data and our own results.
