[Endoscopic surgical technique in appendectomy. Experiences and results of 950 laparoscopic appendectomies].

In a prospective study 950 appendectomies were done consecutively from May 1992 to September 1997. When indication for appendectomy was given all patients were operated on endoscopically. In 5.5% of cases had to be turned to open operation. 17 different surgeons are involved. Even the first appendectomy in adjucation of young residents was done endoscopically. 372 (39.15%) male and 578 (60.85%) female patients were operated. Average age was 25.3 years (4 to 84 years). In 11% of cases so-called chronic recurrent appenditicis as indication was accepted only after careful exclusion of other reasons for complaint. Mean duration of operation time was 44.5 min (15 to 170 min). Hospital stay was influenced subjectively 6.1 day (1 to 19 days). Examination of specimen by the pathologist shows following results: perforated appendicitis 7%; acute appendicitis 50%; chronic recurrent 33%; no pathologic changes 9%; carcinoide or oxyures 1%. The Postoperative complication rate was very small: only 2.7% (relaparotomy because of small bowel obstruction: 4, paracolic abscess after severe phlegmonic inflammation: 4, infected haematomas: 2, relaparotomy because of unobserved deverticula of Meckel with severe inflammation: 1, delayed woundhealing: 8, postoperative pain with duration long than: 24 hours: 7).

Inversion-ligation appendectomy for incidental appendectomy.

Inversion-ligation appendectomy involves the following steps: (1) skeletonizing the appendix from its mesentery; (2) inverting the appendix via a blunt probe into the cecal lumen; (3) ligating the remaining nubbin of tissue; and (4) inverting the nubbin with a purse-string stitch. This procedure allows the surgeon to perform incidental appendectomy while avoiding transection of the appendiceal lumen with its attendant risk of enteric bacterial contamination.

Deriving the indications for laparoscopic appendectomy from a comparison of the outcomes of laparoscopic and open appendectomy.

BACKGROUND: Indications for laparoscopic appendectomy (LA) remain controversial and poorly defined. We sought to identify indications for LA through a comparison of LA and open appendectomies (OA). METHODS: We reviewed demographics, coexisting medical conditions, radiology and pathology data, hospital course, and complications from charts on all LA patients and a comparison group of OA done from 1991 to 1998. RESULTS: The following were significantly associated with LA: female sex, higher mean body mass index (BMI), coexisting medical problems, private insurance, and daytime surgery. The OA group was significantly more likely to have: a radiology report suggesting the diagnosis of acute appendicitis, perforation of the appendix, intensive care unit admission, and complications in their hospital course. Forty-one percent of the LA patients did not have appendicitis, compared with 20% of the OA patients. CONCLUSIONS: Daytime surgery, women, private insurance, coexisting medical problems, prior abdominal surgery, higher BMI, and less severe disease appear to be used by surgeons as indicators for LA. The threshold for surgical exploration appears to be lower for LA.

[Laparoscopic appendectomy in obese patients. A comparative study with open appendectomy].

The aim of this study is to show the advantages of laparoscopic versus classic appendectomy in obese patients. The trial includes 32 obese patients which underwent laparoscopic surgery for appendicitis in our clinic, compared to a similar trial of patients with open surgery. In both o trials we followed-up the operating time, postoperative pain, hospitalization and social and professional reintegration. We noticed that in laparoscopic appendicectomy patients postoperative pain and hospitalization are reduced, the bowel transit restants rapidly and spontaneously, there are no wound complications and patients recover faster. The disadvantages consisted in longer operative time and higher cost of the laparoscopic operation versus classic appendectomy.

[Status and outcome of laparoscopic appendectomy--results of a prospective study of 600 consecutive appendectomies].

In a prospective study 600 consecutive appendectomies were held. In 51 cases the surgery was conventionally ended after laparoscopic beginning. The laparoscopic proceeding was set independently of the dimension of the inflammation. Also the perforation did not exhibit any contraindication. The rate of complications of 8.7% was in the range of the conventional appendectomy. We, however, could show that with increased experience and save technique the morbidity, especially the septic complications could have been sinked to 2%. The duration of hospitalisation amounted on an average of 5.0 days, the surgery time 53.6 minutes. The main advantage of the laparoscopic proceeding is the outstanding overview with the possibility of a diagnostics of the abdominal cavity. Besides an acute appendicitis of which in 14.6% a perforation was present, relevant side findings were elevated in 11.3% which in 7.7% were endoscopic surgically treated at the same time.

[Laparoscopic appendectomy as routine operation for treatment of inflammatory diseases of the appendix. Analysis of 733 laparoscopic appendectomies 6/1992 to 8/1997 in the Reichenbach district hospital].

All laparoscopic appendectomies were analysed retrospectively during 6/1992 and 8/1997 in our hospital. Operation time was 33.6 +/- 12.9 min. In 9 patients the operation had to be converted. Complications occurred in 1.77% (13 patients). 7 complications could be treated laparoscopically and 6 required a laparotomy. The hospital time was 6.4 +/- 2.2 days. The patients needed 1.3 +/- 1.7 days oral analgetics. We believe the laparoscopic appendectomy a reliable operation to treat all inflammatory diseases of the appendix.

[Laparoscopic appendectomy and laparotomy appendectomy: comparison of methods].

The study compares the real advantages of laparoscopic appendicectomy using only a transumbilical trocar, with laparotomic appendicectomy in the management of acute and/or chronic pain in the lower right abdominal quadrant. From May 1997 to April 2000, 88 patients were treated: 27 (group I) with the laparoscopic approach, and 61 (group II) with laparotomy. We compared operating times, incidence of complications, hospital stay and cosmetic result. We also reviewed the literature on this subject over the past ten years. Average operating time was 45 minutes in group I and 30 minutes in group II; complications consisted in 2 cases of omphalitis in the laparoscopic group and 3 infections of the wound and 2 cases of lipolysis of the abdominal wall in the laparotomic group. The average hospital stay was 3.2 days in the laparoscopic group against 4.7 days in the laparotomic group. Resumption of work and sport occurred after 10 to 20 days and 15 to 45 days in groups I and II, respectively. The total cost was lower in the laparoscopic group. The laparoscopic approach appears to be an effective technique for the management of acute and chronic appendicitis, as it allows both treatment of the pathology and diagnosis and treatment of other unknown pathologies, with exploration of the abdominal cavity. In addition, it guarantees a good cosmetic result, a short hospital stay with a low incidence of complications and an advantageous cost/benefit ratio.

Results of laparoscopic vs. conventional appendectomy in complicated appendicitis.

BACKGROUND: Although many trials show some advantages of laparoscopic appendectomy over open appendectomy, the value of laparoscopic appendectomy is still controversial. Specifically the question of whether there are benefits of laparoscopic appendectomy over open appendectomy in complicated appendicitis remains to be answered. METHODS: Of 1,106 consecutive appendectomies (717 laparoscopic appendectomies, 330 open appendectomies, and 59 conversions) between 1989 and 1999, the results of 299 patients with complicated appendicitis (defined by perforation, abscess, or peritonitis) were analyzed retrospectively to compare the complications of laparoscopic appendectomy and conversion (intention-to-treat group) with those of open appendectomy. RESULTS: Complicated appendicitis (n = 299) was treated by laparoscopic appendectomy in 171 patients, by open appendectomy in 82 patients, and by conversion in 46 patients. Laparoscopic appendectomy and conversion showed fewer abdominal wall complications than open appendectomy (13/217; 6 percent vs. 15/82; 18.3 percent; P < 0.003), which led to a decrease of the total complication rate in the intention-to-treat group (21/217; 9.7 percent vs. 19/82; 23.1 percent; P = 0.004). The rate of intra-abdominal abscess formation was nearly the same after laparoscopic appendectomy (4.1 percent) and open appendectomy (4.9 percent). The total complication rate was higher in complicated appendicitis than in acute appendicitis (P < 0.005) but was independent of the laparoscopic technique. The conversion rate was higher in complicated appendicitis than in acute appendicitis (21.2 vs. 2.3 percent; P < 0.001). CONCLUSION: In comparison with open appendectomy, laparoscopic appendectomy (by itself and in an intention-to-treat view) leads to a significant reduction of early postoperative complications in complicated appendicitis and therefore should be considered as the procedure of choice.

Appendectomy in the pre- and postlaparoscopic eras.

The role of laparoscopic appendectomy remains controversial since many authors have suggested that overall morbidity is primarily a function of the degree of appendicitis rather than the operative approach. We have reviewed our appendectomy experience to determine the advantages and/or disadvantages of the laparoscopic technique in cases of acute appendicitis, and furthermore to ascertain whether the extent of disease should affect the surgical approach used. Data were accumulated for all 1158 patients who underwent appendectomy at a single institution during the following three time periods that span the pre- and postlaparoscopic eras: period I (1987 to 1990), period II (1991 to 1993), and period III (1994 to 1997). Cases were categorized with regard to pathologic findings and operative approach (i.e., open or laparoscopic appendectomy). The percentage of appendectomies performed laparoscopically increased with time (0%, 27%, and 79% for periods I, II, and III, respectively). Overall, the total operating room time was slightly shorter for laparoscopic compared to open appendectomy (99 vs. 102 minutes; P<0.05). Operating room times for open appendectomy remained unchanged, but the times for laparoscopic appendectomy decreased from period II to period III (119 to 94 minutes; P<0.001). In cases of gangrenous/perforated appendicitis, the times for laparoscopic appendectomy were significantly shorter than those for open appendectomy (98/115 vs. 120/125 minutes; P<0.001 for both). Overall, the hospital stay was shorter for patients undergoing laparoscopic appendectomy (1.63 vs. 4.21 days; P<0.001), and the difference was maintained in all three time periods. The differences in length of hospital stay for lap-aroscopic vs. open appendectomy were most dramatic in gangrenous/perforated cases (1.8/3.0 vs. 4.0/9.0 days; P<0.001), whereas there was only a slight difference in cases of simple appendicitis, for example, 1.6 vs. 2.1 days (laparoscopic vs. open appendectomy, period III). There was a significant decrease in the percentage of perforated cases in which surgical treatment had been delayed (>8 hours) (21%, 5%, and 5%) over the three time periods, but the rate of "negative" appendectomies was similar (10%, 8%, and 8%). The complication rates following laparoscopic and open appendectomies during period II were 5.4% and 7.5%, respectively (P>0.05). Laparoscopic appendectomy results in a marked decrease in the length of hospital stay and similar postoperative morbidity compared to open appendectomy. In cases of gangrenous or perforated appendicitis, laparoscopic appendectomy appears to be especially worthwhile in regard to both operating room time and hospital stay.

Prospective randomized comparison of open versus laparoscopic appendectomy in men.

A prospective, randomized trial was performed to compare open appendectomy with laparoscopic appendectomy in men with a clinical diagnosis of acute appendicitis. Sixty-four patients with a median age of 25 years (range 18-84 years) were randomized to open appendectomy (n = 31) or laparoscopic (n = 33) appendectomy. Of the 64 men, 56 (87.5%) had appendicitis (27 open, 29 laparoscopic procedures). The mean operating times were 50.6 +/- 3.7 minutes (+/- SEM) for open and 58.9 +/- 4.0 minutes for laparoscopic appendectomy (p = 0.13). Five (15%) patients randomized to laparoscopic appendectomy had an open operation. The mean postoperative hospital stay was significantly longer for open appendectomy (3.8 +/- 0.4 days) than for laparoscopic appendectomy (2.9 +/- 0.3 days) (t = 2. 05,df = 62,p = 0.045). The complication rate after open appendectomy (25.8%) was not significantly different from that after laparoscopic appendectomy (12.1%). There was a single postoperative death due to a pulmonary embolus in the laparoscopic group and a single death due to cardiac and renal failure in the open group. The mean time to return to normal activities was significantly longer following open appendectomy (19.7 +/- 2.4 days) than after laparoscopic appendectomy (10.4 +/- 0.9 days), (t = 3.75,df = 49,p = 0.001). In conclusion, laparoscopic appendectomy in men has significant advantages in terms of a more rapid recovery compared to open appendectomy. There were no significant disadvantages to laparoscopic appendectomy compared to open appendectomy.

A prospective randomized trial comparing open versus laparoscopic appendectomy.

OBJECTIVE: The authors determined whether there was an advantage to laparoscopic appendectomy when compared with open appendectomy. SUMMARY/BACKGROUND DATA: The advantages of laparoscopic appendectomy versus open appendectomy were questioned because the recovery from open appendectomy is brief. METHODS: From January 15, 1992 through January 15, 1993, 75 patients older than 9 years were entered into a study randomizing the choice of operation to either the open or the laparoscopic technique. Statistical comparisons were performed using the Wilcoxon test. RESULTS: Thirty-seven patients were assigned to the open appendectomy group and 38 patients were assigned to the laparoscopic appendectomy group. Two patients were converted intraoperatively from laparoscopic appendectomies to open procedures. Thirty-one patients (81%) in the open group had acute appendicitis, as did 32 patients (84%) in the laparoscopic group. Mean duration of surgery was 65 minutes for open appendectomy and 87 minutes for laparoscopic appendectomy (p < 0.001). There were no statistically significant differences in length of hospitalization, interval until resumption of a regular diet, or morbidity. Duration of both parenteral and oral analgesic use favored laparoscopic appendectomy (2.0 days versus 1.2 days, and 8.0 days versus 5.4 days, p < 0.05). All patients were instructed to return to full activities by 2 weeks postoperatively. This occurred at an average of 25 days for the open appendectomy group versus 14 days for the laparoscopic appendectomy group (p < 0.001). CONCLUSIONS: Patients who underwent laparoscopic appendectomies have a shorter duration of analgesic use and return to full activities sooner postoperatively when compared with patients who underwent open appendectomies. The authors consider laparoscopic appendectomy to be the procedure of choice in patients with acute appendicitis.
