Total Colectomy

Total colectomy and even total proctocolectomy with ileoanal reservoir– are also technically possible by laparoscopy. Laparoscopic Trainer

Laparoscopic Training simulation with Laparoscopic Trainer is a prudent choice.

But it has been the latest technique to join the colorectal laparoscopy arsenal for several reasons:

  1. The duration of the intervention, which in the first publications was generally longer than 6 hours.
  2. The scarcity of cases with this indication. The most frequent indication could be pan-colectomy for ulcerative colitis. And this performs in many of these thin patients through “inexpensive” laparotomies in less than 3 hours of intervention.
  3. The difficulty of approaching the transverse colon and the splenic flexure of the colon.

Duration Of Laparoscopic Intervention

The main reason for the long duration of this laparoscopic intervention, in addition to the length of the procedure, is the need to hem-statically section up to 5 major arterial pedicles (ileocolic, right colic, middle colic, left colic, and superior rectal arteries).

This procedure shortens very significantly with the use of vascular sealing instruments such as Ligature, which add speed and safety compared to endo-cutters with vascular load.

Number And Placement of The Inlets

The other main difficulty is the number and placement of the inlets, since all 4 abdominal quadrants operates on and sometimes the pelvis as well. In our opinion, the patient places in the lithotomy position and well supported for lateral decubitus to both sides. And the number of trocar sheaths will usually be 5, starting with a 10-11 mm sheath in umbilical position for optics.

The other 4 places with a certain degree of “art”: two will places in such a way that it is possible to start the operation with the medial approach mobilization of the right colon as in the right colectomy (e.g., in RIF close to the pubis and in FII, operating between the patient’s legs), but allowing us with that location of inputs the approach of the transverse mesocolon. The mobilization of the left colon does as in the sigmoi-dectomy according to the position of the surgeon, the assistant, and the entrances. For many reasons use of simulators is a practical choice like Laparoscopic Trainer.

Approach To the Transverse Colon

The most delicate technical part of this intervention is the approach to the transverse colon, access to the omentum cavity and dissection of the splenic flexure of the colon. The main risks of this phase are injury to the pancreas.

By confusing dissection planes and continuing the section of the transverse mesocolon behind instead of in front of the body of the pancreas. Also, major vascular injury to the root of the mesentery when dissecting the origin of the middle colic artery and vein. For this reason, some authors recommend sectioning its right and left branches.

Procedure (Laparoscopic Trainer)

Instead of the main trunk (and this is the reason cancers of the splenic flexure of the colon usually considers a contraindication for laparoscopic resection). An essential aid to avoid these technical errors is to raise the transverse colon high to “separate” its mesocolon from the pancreas and the root of the mesentery.

The simplest method that we know of is to pass a thread with a straight needle into the abdominal cavity transparietal, pass the needle through a buttonhole in the mesocolon, and bring the needle out again through the same place in the skin: a simple traction with a needle clamp. Crile in the two ends of the thread excellently presents the transverse mesocolon.

Once the medial approach of the entire colic framework completes, the splenic flexure of the colon releases (for this it is usually necessary to place a trocar sheath in the epigastrium or in HCD that complements the IIF sheath), and the right Toldt’s fasciae sections. And left, until all the segments of the colic frame reach the umbilical area.

Once this achieved, the laparoscopic part of the intervention ends: the umbilical inlet widens and protected, through which the total colectomy specimen removes, excised and the open ileocolic anastomosis performs.

The Issue of Laparoscopy Indicated for Colorectal Cancer

In a bibliographic review carried out by us (unpublished data) on colorectal cancer operated by laparoscopy, from 1995 to 2002. We found 17 series of laparoscopic surgery (or comparisons with laparotomy surgery) that bring together more than 2,000 patients with colorectal cancer. That operates by laparoscopy (448 patients who underwent surgery for rectal cancer).

The conversion rate in these series ranges between 3 and 33%, with mortality less than 5%, and mean morbidity of 16%. Global recurrences range between 3 and 38%, with local recurrences of 1-21%. The highest rate of trocar implantation is 2.6%, but 10 series did not detect implants in trocar wounds.

Stage Of Disease-Free Survival

All the series present an overall rate of disease-free survival greater than 70%, more than 90% in stage I, more than 70% in stage II, and between 49 and 88% in stage III. Survival rates are significantly poorer in rectal cancer series. None of the randomized studies show worse survival rates in laparoscopy than in open surgery. However, the greater technical difficulty of surgery for rectal cancer called into question in 2002 whether it was technically feasible and safe.

Implants Laparoscopy in Colon Cancer

Regarding implants in trocar wounds, the alarming results 4 of the first years have not been significant, as since shows. However, widespread optimism regarding the liberalization of this laparoscopic cancer surgery. This prompts by randomized trials and is likely to lead to an increase in trocar wound implants, to the extent that surgical groups are unaware of this.

The experience of experts cannot generalize without adequate education and training. In non-comparative series of laparoscopic surgery for cancer with long follow-up good results shows, as well as in all the randomized studies, from the first with less than 2 years of follow-up, to follow-ups close to 5 years, 20 and, above all, the American 22 and European 48 multicenter studies.

Rate Of Conversion to Laparotomy of The Technique

The rate of conversion to laparotomy in colorectal surgery is almost never less than 5% (and in some series it reaches 30%), even though there are very experienced groups that have less than 5% in inflammatory pathology (especially diverticulitis). This attributes to the acute inflammatory condition and its consequences, which make the technique notably difficult.

However, about cancer, more representative studies of the general population of surgeons, such as multicenter studies, also find high conversion rates (18-21%), 49 probably because a priory two-thirds of colon cancer cases are amenable to laparoscopy. Most of the conversions here are due to invasion of other organs or difficult locations.

Implants In Laparotomy Surgery

In particular, the issue of implants in cancer surgery already resolves both at the level of experimental demonstration. In clinical series 52 and randomized studies 20, and it finds in figures of less than 1%, very similar to those of laparotomy surgery. It seems clear that the high numbers of trocar implants are due to inexperience and poor surgical technique, so that in laparoscopic surgery for cancer some recommendations must always observes, which shows.

However, the fundamental issue in this section should be the overall cure rates, recurrence rates, and cancer-free survival rates between comparable cases operated by laparoscopy and by laparotomy. This is currently a question resolved by randomized, single-20 and multicenter studies. The results of these studies –with the highest level of scientific evidence– make it possible to ensure that these rates are identical between both approaches, that is, that the curability of colon cancer is equally feasible by well-done laparoscopy than by well-done laparotomy.

The Specific Issue of The Laparoscopic Approach in Rectal Cancer

Just as several of these studies already concludes with level I of scientific evidence regarding the equality of survival and cure of colon cancer between laparoscopy and laparotomy. This not studies with the same level of evidence for colon cancer of the rectum. Moreover, more difficult to cure than colon cancer.

In recent years, open surgery for rectal cancer has achieved excellent results, combining multidisciplinary treatments and total excision of the mesorectum. Compared to these more current results, the laparoscopic approach to rectal cancer compares. But such comparative studies do not exist. Some pioneer authors 11have shown excellent survival results in 201 cases of colon and rectal cancer operated on with a mean follow-up of 4 years: 100% in stage I, 88% in stage II and 64% in stage III.

Results To Rectal Cancer

The question is whether these results are also transferable to rectal cancer. In this sense, there are several contributions, some published and others referred to in congresses. This presents excellent results, although they are consecutive series and not comparative with laparotomy surgery. With the consequent lower impact on scientific evidence.

These are 3 communications to congresses, specific to laparoscopic resection for rectal cancer. (Unpublished data: Leroy, Feliciotti and Schiedeck). Totaling 448 cases (with a mean follow-up of 3 to 5 years), and showing disease-free survival. Stage I disease from 78-91%, stage II from 71 to 88%, and stage III from 50-60%.

The German multicenter study, which includes colon cancer and rectal cancer, offers these results: 399 cases with 30-month follow-up and disease-free survival of 98% in stage I, 85% in stage II, and 75% in stage III. There is only one short randomized study of resection for “recto-sigma” cancer, but there are no randomized studies for low rectal cancer.

Conclusion

What does seem to be sufficiently proven is that one of the requirements of modern rectal cancer surgery-total excision of the mesorectum is achievable by laparoscopy in a good proportion of cases. with low local recurrence (2%), low mortality (2%), 36% morbidity (17% anastomotic leaks) and 27% mortality from cancer, with a mean follow-up of 45 months.
