Avoiding complications after laparoscopic esophago-gastric banding: experience with 400 consecutive patients.

BACKGROUND: Among bariatric operations, laparoscopic adjustable gastric banding (LAGB) has been the preferred one in Europe and Australia, and has become recently popular in the USA. Like every surgical procedure, however, it is not devoid of specific complications, like slippage, band erosion, outlet obstruction and port problems. Assuming that the absence of the pouch may avoid postoperative slippage, we introduced the technique of esophago-gastric placement, instead of the original gastric banding technique. A further technical variant, introduced in June 2002, consists of suturing the gastric fundus to the left hemidiaphragm, using two non-resorbable sutures and pledgets. METHODS: Between January 1999 and July 2005, 400 LAGBs have been placed in 90 males and 310 females, with the technical variants above. Mean age was 42 (range 17-69 years), and mean BMI was 44.8 kg/m(2) (range 33-67). RESULTS: Mean hospital stay was 2.5 days (range 1-17). Mortality has been zero. Major complications included: 16 slippages (after a range of 6-45 months), 5 outlet obstructions (immediately after the operation), and one intragastric migration (after 2 years). Minor complications included 18 port problems. Since the introduction of gastric fundus fixation to the diaphragm in 2002, gastric slippage has decreased from 8% to 0.9%. BMI has decreased from 44.8 to 32 kg/m(2) at 60 months. CONCLUSIONS: The technique herein presented is effective and useful to prevent postoperative gastric slippage. It does not induce pseudo-achalasia, if strictly controlled. In fact, it is avoided by the patient due to the immediate appearance of dysphagia, in the case of wrong food ingestion. Long-term clinico-radiological follow-up confirms that the technique is safe and effective in motivated patients with good compliance and willing to undergo periodic studies.

Conversion rate in laparoscopic cholecystectomy: evolution from 1993 and current state.

The definition of difficult laparoscopic cholecystectomy (LC) is inconsistent. The aim of this study was to analyze the factors that make LC difficult to perform and determine ways to avoid conversion, based on our series. All patients who underwent LC or open cholecystectomy (OC) between January 1993 and December 2001 in our division of general surgery were the subject matter of this study. Preliminary decisions regarding LC or OC were avoided. Our experience (1993-2001) was based on 1360 consecutive elective LC procedures in 381 male and 979 female patients. The mean age of the patients at operation was 53 years (range, 17-84). The median operating time was 55 minutes (range, 35-180). The overall conversion rate was 1.8%. Indications for conversion included surgical difficulty during the laparoscopic procedure and anesthesia issues. The conversion rate has decreased to less than 1% in recent years. There were no mortalities, and the postoperative complication rates were low. The mean hospital stay of the patients was 2.6 days. In conclusion, based on our experience, we suggest limiting OC to patients with proven contraindications to LC (i.e., Mirizzi syndrome or systemic illness incompatible with pneumoperitoneum), attempting LC in all other cases, and considering cholecystostomy and delayed LC as an alternative to conversion during difficult LC.

Laparoscopic appendectomy for acute and recurrent appendicitis: retrospective analysis of a single-group 5-year experience.

BACKGROUND AND PURPOSE: Twenty years after the first report of laparoscopic appendectomy (LA), its role in the treatment of appendicitis is still under debate. We report herein a retrospective analysis of our cases of LA in the last 5 years, during which we adopted a policy of an almost uniform laparoscopic approach on a rather selected population composed mainly of women with acute or recurrent lower quadrant abdominal pain. PATIENTS AND METHODS: Laparoscopic appendectomy was performed on 33 male and 98 female patients. The mean age at operation was 25.7+/-11.4 years (range 11-59 years). Acute appendicitis with localized or diffuse peritonitis was present in 34 cases. In the remaining 97 patients, the operation was performed for acute or recurring symptoms of lower quadrant abdominal pain. RESULTS: There were no conversions to open surgery. The operating time was 45+/-17 minutes (range 30-110 minutes). The pathology examination of the removed appendices showed acute appendicitis in 34 cases and chronic inflammation in the remaining 97 patients. In one case, histology revealed a coexisting mucinous carcinoid that extended to the perivisceral fat, and a completion right hemicolectomy was performed. Complications were minor in most cases. Reoperation for deep abdominal abscess or hematoma was required in three cases. The mean hospital stay was 2.59+/-1.58 days (range 24 hours-11 days). CONCLUSION: In our hands, LA has proven to be safe and effective. The laparoscopic operation has significant advantages in terms of lower invasiveness and better diagnostic capability. It is especially useful in women of child-bearing age, in whom it may be considered the procedure of choice.

Laparoscopic adjustable esophagogastric banding: preliminary results.

BACKGROUND: Laparoscopic gastric banding is effective in surgical treatment of morbid obesity, but has had the drawback of specific complications, like slippage and gastric erosion. To prevent such complications, modifications have been used, including high retrogastric positioning above the bursa omentalis, complete anterior fixation by gastro-gastric stitches over the band, and reduction of the pouch volume to < or = 15 ml. These technical variants may induce dysphagia. METHODS: We adopted a different technique, consisting of placement of the band (9.75 cm BioEnterics Lap-Band) around the esophagus just above the cardia, to induce an amplification of the dysphagic mechanism. No fixation stitches were used. RESULTS: From January 1999 to March 2001, 80 consecutive patients (16 males, 64 females, mean age 41 years, average BMI 45) were operated this way. All operations were completed laparoscopically. However, in 1 patient the procedure had to be interrupted for bleeding from a large fatty liver injury by the retractor. Complications included 2 cases of slippage: an early one after 24 h, requiring surgical removal, and a late one after 9 months, treated by laparoscopic repositioning. The third complication, a reactive esophageal stenosis, occurred in a transsexual male on estrogen treatment, that needed replacement with a wider Swedish band. Band adjustment was required in 28 patients, one time in 22 cases and twice in the other 6. Mean BMI decreased from 45 to 38 after 6 months, remaining at 37 after 24 months, while excess weight was reduced by 50% at 24 months. CONCLUSIONS: The technique has a re-educational function, in that patients are induced to chew thoroughly, to introduce small morsels of food and to prolong the mastication time, in order to avoid dysphagia. Laparoscopic adjustable esophagogastric banding gave no problem if well positioned, and promoted new alimentary habits through a dysphagic mechanisms, inducing significant excess weight loss.
