Do complications related to laparoscopic cholecystectomy influence the prognosis of gallbladder cancer?

BACKGROUND: Laparoscopy is thought to worsen the prognosis of gallbladder cancer (GBC) discovered unexpectedly at laparoscopic cholecystectomy (LC). However, laproscopy has never been shown to have an influence on patient survival in clinical series. METHODS: We Performed a two-center retrospective analysis of 28 patients with GBC (11 previously known, 17 unexpectedly discovered by LC) to determine whether laparoscopy and complications related to LC had any influence on the prognosis of GBC. Resectability for cure after LC, survival, and recurrence related to both the procedure itself and complications associated with LC were analyzed. RESULTS: Of the 17 patients with unexpected GBC, 16 were considered resectable for cure at the time of LC. Advanced disease was detected in eight patients by re staging (n = 5) or exploration (n = 3). Seven patients (43.8%) underwent reoperation for cure. Mean survival of patients with unexpected GBC was 26.5 months. Mean survival was shorter when complications (bile spillage, injury of common bile duct, or tumor violation) occurred during LC (10.2 vs 33 months, p = 0.016). If bile spillage was the only complication at LC, there was also a trend to shorter survival (12 vs 33 months, p = 0.061). CONCLUSION: Complications during LC significantly worsen the prognosis of GBC. Therefore, bile spillage and excessive manipulation of the gallbladder should be avoided.

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.

[Laparoscopic versus conventional appendectomy--a comparison with reference to early postoperative complications].

OBJECTIVE AND METHODS: To compare the complications of laparoscopic appendectomy (LA) and conventional appendectomy (CA) 930 consecutive patients from 1989 until 1997 were analysed retrospectively. RESULTS: Conventional appendectomy was performed in 330 patients, laparoscopic in 554 patients and another 46 patients required conversion after laparoscopy. The groups were similar in sex ratio, age and degree of inflammation. Postoperative complications occurred in 8.78%. There were less complications in the LA-group (4.69%) than in the CA-group (13.33%) (p < 0.01), especially wound infections were found less in the LA-group (1.8% vs. 11.21%, p < 0.01). The incidence of intraabdominal abscesses was similar in the LA and CA group (1.44% vs. 1.52%). The differences between the groups are not influenced by complicating appendicitis (perforation or abscess). Systemic complications were similar for LA and CA (0.72% and 0.61%), but were seen more often after conversion (6.52%, p < 0.01). CONCLUSIONS: This retrospective analysis shows that laparoscopic appendectomy significantly reduces postoperative complications, especially wound infections. The authors consider laparoscopic appendectomy to be the procedure of choice in patients with acute appendicitis.

[Laparoscopic transperitoneal inguinal hernia repair (TAPP)--complications and results of a prospective study].

Results of a prospective study of 776 TAPP procedures performed on 600 patients are reported. We found rates of 0.5% for intraoperative complications and 1.3% for early-postoperative complications. Late postoperative complications have been observed in an incidence of 4.4% for haematomas, 7.9% for scrotal discomfort, 1.2% for hyperaesthesia and trocar hernias have occurred in 0.9%. The recurrence rate was 3.9%. Results suggest that improvement of the technique of laparoscopic hernia repair may prevent complications and may lower future complication rates.
