ALTERNATIVE TECHNIQUE FOR CHOLECYSTECTOMY COMPARABLE TO SINGLE PORT

LAPAROSCOPIC PERITONEAL DIALYSIS CATHETER PLACEMENT WITH RECTUS SHEATH TUNNELING: A ONE-PORT SIMPLIFIED TECHNIQUE

BACKGROUND

The success of peritoneal dialysis depends on the proper placement and functional longevity of the dialysis catheter. Laparoscopic implantation of a catheter through a rectus sheath tunneling can minimize the risks of catheter failure.

AIMS

This study aims to describe one-port simplified technique for laparoscopic placement of a peritoneal dialysis catheter with rectus sheath tunneling.

METHODS

The simplified laparoscopic insertion of a Tenckhoff catheter with rectus sheath tunneling was performed in 16 patients with chronic renal failure.

RESULTS

During the follow-up period, no major complications occurred. Three patients were excluded. One was referred to the renal transplant some weeks after implantation, and one died for other reasons during the follow-up. Another patient needed adhesiolysis due to previous surgery, so an additional port was necessary. The other 13 catheters worked properly, and no postoperative hemorrhage, early leaks, hernia, or catheter migration occurred. One patient had a tunnel infection 11 months after the implant. No peritonitis was observed during the follow-up.

CONCLUSIONS

The technique is simple, reproducible, and safe, with good results in catheter function, few complications, and a high catheter survival rate. It does not require a special device or trocar and avoids excessive port sites.

DOES MALE GENDER INCREASE THE RISK OF LAPAROSCOPIC CHOLECYSTECTOMY?

Background:

Laparoscopic cholecystectomy is the preferable treatment for chronic or acute cholecystitis. Some factors may increase the rate of laparoscopic conversion to open cholecystectomy and perioperative complications. The role of gender as a risk factor for laparoscopic cholecystectomy is controversial.

Aim:

To evaluate the role of the gender on the operative findings and outcome of laparoscopic cholecystectomy.

Method:

All patients who underwent laparoscopic cholecystectomy for chronic or acute cholecystitis were included. Demographic, clinical, laboratory, imaging exams, intraoperative and postoperative data were obtained and analyzed. The data was obtained retrospectively from electronic medical records and study protocols.

Results:

Of a total 1,645 patients who were subjected to laparoscopic cholecystectomy, 540 (32.8%) were men and 1,105 (67.2%) were women. Mean age was similar in both genders (p=0.817). Operative time has longer in the male (72.48±28.50) than in the female group (65.46±24.83, p<0.001). The rate of acute cholecystitis was higher in the male (14.3%) than in the female group (5.1%, p<0.001). There was no difference between the genders in regard to the rate of conversion (p=1.0), intraoperative complication (p=1.0), postoperative complication (p=0.571), and operative mortality (p=1.0).

Conclusion:

Male gender is not an independent risk factor for laparoscopic conversion and perioperative complications.

SINGLE PORT LAPAROSCOPIC CHOLECYSTECTOMY: TECHNICAL ASPECTS AND RESULTS

Background:

The search for less traumatic surgical procedures without compromising efficacy and safety, together with the technological advances and greater experience of the teams, led to the development of operative techniques with increasingly smaller incisions, the so-called “minimally invasive surgeries”.

Aim:

To evaluate the technical aspects and results of single port cholecystectomy.

Method:

Were analyzed 170 patients between 18-74 years submitted to videolaparoscopic cholecystectomies by single port, regardless of elective or urgent indication, without restriction of patient selection.

Results:

Among the 170 operations, 158 were exclusively performed by single port, and the conversion rate was 7% (inclusion of other accessory trocars or conversion to multiportal). Conversion to open surgery occurred in three cases (1.76%). The mean surgical time was 67.97 min, showing a marked decrease when was reached close to 50 cases and a stabilization after 100 surgeries. The overall complication rate was 10%, with minor complications such as: incisional pain, hematomas, granulomas, port access hernias (9.41%).

Conclusion:

Single port cholecystectomy can, after standardization and surgical team training, be a safe surgical procedure associated with a recognized aesthetic advantage.

COMPARISON BETWEEN INCIDENCE OF INCISIONAL HERNIA IN LAPAROSCOPIC CHOLECYSTECTOMY AND BY SINGLE PORT

Background:

Surgeries with single port access have been gaining ground among surgeons who seek minimally invasive procedures. Although this technique uses only one access, the incision is larger when compared to laparoscopic cholecystectomy and this fact can lead to a higher incidence of incisional hernias.

Aim:

To compare the incidence of incisional hernia after laparoscopic cholecystectomy and by single port.

Methods:

A total of 57 patients were randomly divided into two groups and submitted to conventional laparoscopic cholecystectomy (n=29) and laparoscopic cholecystectomy by single access (n=28). The patients were followed up and reviewed in a 40.4 month follow-up for identification of incisional hernias.

Results:

Follow-up showed 21,4% of incisional hernia in single port group and 3.57% in conventional technique.

Conclusions:

There was a higher incidence of late incisional hernia in patients submitted to single port access cholecystectomy compared to conventional laparoscopic cholecystectomy.
