Laparoscopic appendectomy by ultrasonically activated scalpel in acute appendicitis: preliminary report.

BACKGROUND AND PURPOSE: Laparoscopic appendectomy (LA) is increasingly being used in treating acute appendicitis. New instruments such as the ultrasonically activated scalpel (UAS) have been introduced for most laparoscopic procedures. We evaluated the use of UAS in the performance of LA, as the potential of this instrument in this type of surgery remains to be defined. PATIENTS AND METHODS: Three patients with acute right lower abdominal pain were managed by the laparoscopic approach. Once the diagnosis of acute appendicitis was established, laparoscopic appendectomy was performed with the UAS. RESULTS: The mean operative time was 42.3 minutes (range 32-49 minutes). There were no complications related to the treatment with UAS of either the vascular pedicle or the appendicecal stump. No electrosurgical coagulation, clips, loops, or endostapler was used in any patient. CONCLUSIONS: Total LA performed with UAS is feasible. Use of the UAS may make dissection and resection of the appendix easier, helping to reduce the mean operative time.

Acute diverticulitis and diverticular disease of the colon: a safe indication for laparoscopic surgery.

AIM: We analyzed our experience with a laparoscopic method for the treatment of acute diverticular disease. METHODS: Between January 1994 and October 1999 a group of 52 patients who fulfilled the criteria for symptomatic diverticular disease in the descending and sigmoid colon underwent laparoscopy with resection of an average of 40 cm of the bowel. Intraabdominal mechanical anastomosis completed the procedure. RESULTS: The use of ultrasonic scissors made the laparoscopic technique easier and shortened operative time. Operative morbidity was 15%. Two patients with acute diverticulitis and associated sepsis were reconverted to open surgery, and 4 patients presented postoperative rectal bleeding which ceased spontaneously. No long-term complications were found except in 1 patient who developed an incisional hernia through an entry port. Oral intake began between the second and third day. Postoperative hospitalization was 3-8 days (mean: 5.5 days) and mean operative time was 130 min (range: 70-240 min). CONCLUSIONS: Despite the steep learning curve for this type of surgery, the good morbidity and mortality rates with the laparoscopic method, especially with high-risk groups of patients (age > 65 years, high blood pressure, etc.) suggest that this surgical option can be used efficiently and safely, and that it achieves better results than with open surgery. However, we feel that the treatment of patients with acute complications of diverticular colon disease requires extensive experience with laparoscopic colorectal surgery.

Intragastric migration of laparoscopic adjustable gastric band (Lap-Band) for morbid obesity.

The appearance of fistulas and the posterior intragastric inclusion of the adjustable silicone Lap-Band prothesis have been described, representing a severe complication of the Lap-Band procedure. A 45-year-old patient with severe obesity, weighing 115 kg, and having BMI (body max index) of 45 kg/m2 was assigned to a protocol to place a Lab-Band in her. An infection in the reservoir after 9 months indicated the beginning of the appearance of fistulas. The entire adjustable silicone gastric band device eroded inside the stomach between months 9 and 14 after its placement, resulting in reoperation. The gastric inclusion of the Lap-Band device represents a severe complication that requires reoperation, and raises concerns about the safety of this new alternative weight reduction operation.

Vertical ring gastroplasty (VRG) in the treatment of the serious clinical obesity. Results and complications.

OBJECTIVE: The morbid obesity is a serious polysystematic disease to which it is necessary to offer a surgical solution when the conservative alternatives fail. METHODS: In a period of five years, 50 patients with vertical ring gastroplasty (VRG) have been evaluated and protocolized in the program of surgery of the morbid obesity, with an average weight of 134.3 kg corresponding to an overweight and body mass index (BMI) average respectively, of 69.7 kg and 49.8 kg/m2. RESULTS: The early morbidity has been scarce and the postoperative average stay of 7 days. The decrease of the percentage of weight, overweight and BMI was maximum 2 years later, with losses of 52 kg, with a percentage of loss of average overweight of 76.8% and a fall of 21 points in the BMI; however there was a partial recovery of the indexes in the following years. The accompanying pathology was solved in the period of studied time, although 84% of the patients referred vomits and practically 100% dietary limitations. CONCLUSIONS: The gastroplasty is a quick, simple technique and of scare morbimortality, although it is being subjected to criticism for the restrictions in the diet, quality of life and disruptions of the line of clamped. However, nowadays there is not a consensus on the ideal bariatric solution, and as a surgical alternative, the vertical gastroplasty can represent one of the techniques of choice for certain selected types of serious obesity.

Surgical treatment of the acute cholecystitis in the laparoscopic age. A comparative study: laparoscopy against laparatomy.

OBJECTIVE: The aim of this study was to assess the complications and results of the laparoscopic opposite to open treatment of the acute cholecystitis. METHODS: A retrospective randomized study with two groups of 30 patients each one. The parameters tested were age, sex, risk factors, surgical time, hospital stay, cholecystitis type, and early or late complications. RESULTS: In the two groups there were no significant differences in age, sex, risk factors, type of cholecystitis and surgical time. The average of hospital stay was significantly longer for open cholecystectomy (9.5) than for laparoscopic technique (2.30) (p < 0.001). The complication rate was higher (7.30%) in open cholecystectomy. CONCLUSIONS: The laparoscopic cholecystectomy should be the standard procedure for the treatment of the acute cholecystitis.

Gallbladder and cystic duct absence. An infrequent malformation in laparoscopic surgery.

Gallbladder absence is an infrequent anomaly normally accompanied by lack of the cystic duct. Of unknown etiology, in general it is accepted to be a congenital malformation. A male patient (age 59) diagnosed with nonfunctional symptomatic scleroatrophic gallbladder by echography and ERCP was operated on using a laparoscopic approach. Gallbladder and cystic absence was diagnosed during the procedure. A new case of gallbladder and cystic duct absence, diagnosed by laparoscopy, is presented. This type of extrahepatic bile duct malformation is quite rare, but it must be taken into account due to the generalization of laparoscopic surgery in biliar pathology because of the high risk of serious lesions to the hepatocholedochal system.

[Appendicular invagination].

Two cases of intussusception of the appendix are reported. The first case stands out for its rarity, corresponding exclusively to intussusception of appendicular mucosa. The second case was due to cystoadenoma of the appendix. Both cases were treated by right hemicolectomy due to the difficulty of diagnosing the condition.

[Digestive hemorrhage caused by vascular malformation (Rendu-Osler-Weber). A diagnostic and therapeutic challenge].

We present a case of gastrointestinal bleeding due to vascular malformation (Osler-Weber-Rendu disease), without cutaneous manifestations but with mucous manifestations and familiar and personal history of epistaxis. Until diagnosis, the patient underwent multiple radiologic and endoscopic tests and two surgical procedures. We would underline the diagnostic and therapeutic difficulty of recurrent gastrointestinal bleeding secondary to vascular malformation.

[Anisakiasis as a cause of acute appendicitis and rheumatologic picture: the first case in medical literature].

We report a case of acute abdomen due to appendicular lumen occlusion by anisakis larvae. This is the first case of human anisakiasis known in Spain, and the first case of acute appendicitis, in the medical World literature, produced by this nemathode. The association of myalgias and arthralgias stands out, being in this aspect the second case found the in medical litterature.

Decrease in plasma levels of vasoactive intestinal polypeptide in short bowel syndrome: experimental study.

To investigate the behaviour of the vasoactive intestinal polypeptide (VIP) in short bowel syndrome (SBS), an experimental model of massive intestinal resection (MIR) was developed. For this purpose, 20 'minipigs' were divided into two experimental groups: A (control) and B (MIR). The parameters determined were the mean plasma levels of VIP and the degree of steatorrhea at four different times: T1 (basal), T2 (one week after surgery), T3 (two weeks after surgery), and T4 (24 weeks after surgery). The results indicated that, after MIR, a progressive decrease in the mean plasma levels of VIP takes place, with statistical significance in T3 (p < 0.05) and T4 (p < 0.01). This situation seems to be a direct result of the massive loss of intestinal tissue, and could lead to the use of this peptide to mark the evolution of the intestinal adaptation process.
