Esophageal resection and immediate reconstruction in esophageal perforations.

BACKGROUND: Esophageal perforation is a disease with high mortality. Treatment is controversial and should be individualized. Elapsed time, location and perforation all play a role in determining the treatment option: from conservative treatment to esophagectomy. We undertook this study to report on primary esophagectomy and reconstruction in esophageal perforations with expert surgeons and selected patients. It is worth noting the rare complication of perforated peptic ulcer on Barrett's esophagus presented in one of our patients. CLINICAL CASES: We report two patients with esophageal perforation (one spontaneous and another due to pneumatic esophageal dilation) treated by primary esophagectomy and reconstruction. The patient with spontaneous perforation had Barrett's esophagus with severe dysplasia and perforated peptic ulcer. CONCLUSIONS: Esophageal resection and immediate reconstruction is controversial. It was decided to resect the esophagus in both cases reported here due to the size of the perforation and esophageal disease in the second case. The primary reason for immediate reconstruction in selected cases is permanent resolution. Primary cervical esophagealgastric anastomosis has a lower risk of contamination and leaks than thoracic anastomosis, resulting in mediastinal drainage and parenteral nutrition. Spontaneous esophageal perforation due to perforated Barrett's ulcer is uncommon. Finally, we must consider the importance of early diagnosis and treatment. It is essential to consider the size of the perforation, location, previous esophageal disease, age and general status of the patient in order to undertake appropriate management. Emergency surgery should be individualized and depends on surgeon's experience.

Risk of gastrojejunal anastomotic stricture with multifilament and monofilament sutures after hand-sewn laparoscopic gastric bypass: a prospective cohort study.

BACKGROUND: Gastrojejunal (GJ) stricture is one of the most common late complications after laparoscopic Roux-en-Y gastric bypass (LRYGBP) with a hand-sewn anastomosis. The object of this study was to assess the risk of stricture for two types of resorbable suture (multifilament and monofilament) in a series of LRYGBPs performed by the same surgeon. DESIGN: Prospective cohort study. The study population consisted of a series of consecutive morbidly obese patients who underwent primary hand-sewn LRYGBP between March 2004 and May 2008 at the University Hospital in Getafe, Madrid, Spain. The study comprised 242 LRYGBPs with a four-layer continuous hand-sewn anastomosis using absorbable 3/0 gauge suture. The suture material was Ethicon Vicryl multifilament in the first 105 cases and Ethicon Monocryl monofilament in the following 137 cases. All patients were followed up monthly for the first 6 months and then every 6 months after that. RESULTS: The mean BMI was 46 +/- 4 for the multifilament cohort and 48 +/- 6 for the monofilament cohort with no significant difference between the two (p = 0.567). There were no anastomotic leaks, and no cases of marginal ulcer, abscess, abdominal sepsis, deep vein thrombosis, or pulmonary embolism were recorded. No cases required conversion to open surgery, and perioperative mortality was zero. In all, 11 cases of stricture (4.4%) were recorded, 10 in the multifilament suture cohort (9.5%), and only one in the monofilament suture cohort (0.7%; p = 0.001). The odds ratio was 14.3 (95% CI = 1.8-113.4). The mean outpatient follow-up period was 30 months (range = 6-42). CONCLUSIONS: Anastomotic GJ stricture is a common and well-known complication of laparoscopic gastric bypass for morbid obesity. Hand sewing with monofilament suture significantly lowered the frequency of this complication, and hence, monofilament should be the suture material of choice for this suturing technique.

[Gastric bypass and laparoscopic biliopancreatic diversion with manual anastomosis: results in 250 morbidly obese patients]. / Bypass gástrico y derivación biliopancreática laparoscópica efectuadas con anastomosis manual. Resultados en 250 pacientes obesos móbidos.

BACKGROUND: Gastrojejunostomy anastomosis after a gastric bypass or biliopancreatic diversion can be performed by staples or hand-sewn technique. The aim of this study is to analyze totally hand-sewn anastomosis by laparoscopy. METHODS: Morbid obese patients treated consecutively with a gastric bypass or biliopancreatic diversion in which the main anastomosis was performed with a totally hand-sewn gastrojejunostomy by laparoscopy at Hospital Universitario de Getafe from March-01 to November-07. RESULTS: 250 patients were included: 232 were gastric bypass and the remaining 18, biliopancreatic diversion. Mean BMI was 46 +/- 4. There was only one case of digestive bleeding for a marginal ulcer during immediate postoperative period (6th day). Later, there were 2 cases of complicated ulcers: due to bleeding and perforation. There were no anastomotic leaks from the hand-sewn gastrojejunostomy. A patient was re-operated on 48 hours after bypass due to a leak secondary to a thermal perforation at the lesser curvature. Radiological or endoscopic dilatation were required in 11 stenosis (4.4%) at gastrojejunostomy and none in the biliopancreatic diversion group. Mean surgical time for the anastomosis was 40+/-15 minutes. There were no deaths, sepsis, abdominal abscess, deep venous thrombosis or pulmonary embolism. Average hospital stay was 5.1+/-2.4 days. CONCLUSIONS: Even though most surgeons believe that staples anastomosis is easier, hand-sewn technique can be reproducible by surgeons with laparoscopic sutures experience. This technique has a longer operation time but continuous training provides advanced laparoscopic skills and significantly reduces operation time.

Bypass gástrico y derivación biliopancreática laparoscópica efectuadas con anastomosis manual. Resultados en 250 pacientes obesos móbidos / Gastric bypass and laparoscopic biliopancreatic diversion with manual anastomosis: results in 250 morbidly obese patients

Introducción. En cirugía bariátrica, la reconstrucción del tracto digestivo tras un bypass gástrico (BPG) o una derivación biliopancreática (DBP) se efectúa mediante una anastomosis gastroyeyunal mecánica o manual. El objetivo de este trabajo es analizar la anastomosis gastroyeyunal con sutura manual por laparoscopia. Pacientes y método. Serie de pacientes obesos mórbidos tratados con BPG o DBP con anastomosis gastroyeyunal por técnica manual vía laparoscópica en el Hospital Universitario de Getafe, desde marzo de 2001 a noviembre de 2007. Resultados. Se incluyó a 250 pacientes, de los que 232 fueron intervenidos por BPG y los 18 restantes, por DBP. El índice de masa corporal medio era 46 ± 4. Sólo se registró un caso de hemorragia digestiva (0,4%) por ulcus en la boca en el postoperatorio inmediato (sexto día). En el postoperatorio tardío hubo 2 casos de ulcus complicado (0,8%), 1 caso con hemorragia y 1 con perforación. No hubo ninguna fuga de la anastomosis. Una paciente fue reintervenida a las 48 h por una fuga secundaria a una perforación térmica en la curvatura menor del reservorio gástrico. Se registraron 11 (4,4%) estenosis, que precisaron dilatación radiológica o endoscópica; no hubo ninguna en los casos de derivación. El tiempo medio para la anastomosis fue de 40 ± 15 min. No hubo mortalidad ni se registró ningún caso de absceso, sepsis abdominal o tromboembolia. La estancia hospitalaria media fue de 5,1 ± 2,4 días. Conclusiones. Aunque la mayoría de los cirujanos consideran que la anastomosis mecánica es más sencilla, la técnica manual puede ser reproducida por cirujanos con experiencia en el manejo de suturas y nudos intracorpóreos. La técnica prolonga el tiempo quirúrgico, pero un entrenamiento continuo desarrolla la destreza del cirujano y acorta significativamente el tiempo operatorio The increased use of biomaterials for the repair of abdominal wall hernias has achieved a significant reduction in recurrences and consequently improved the quality of life of patients. However, the appearance of complications such as infection may require the implanted prosthetic material to be removed in a considerable number of patients. A possible treatment option in areas compromised by infection is the implant a biocompatible prosthetic material to generate, or induce the formation of a support tissue so that, in a second stage, the definitive repair of the parietal defect may be undertaken. This is the main goal of bioprostheses. These implants are composed of collagen of animal (usually porcine) or human origin. They should be acellular and fully biocompatible so that they induce a minimal foreign body reaction and immune response (AU)

Laparoscopic hand-sewn gastrojejunal anastomoses.

BACKGROUND: Reconstruction of the digestive tract during gastric bypass (RYGBP) or biliopancreatic diversion (BPD) involves a mechanical or a hand-sewn gastrojejunal anastomosis. The object of this paper is to assess laparoscopic hand-sewn gastrojejunal anastomoses. METHODS: A series of morbidly obese patients was treated with RYGBP or BPD with a laparoscopic hand-sewn gastrojejunal anastomosis at the Hospital Universitario de Getafe-Madrid (Spain) between March 2001 and November 2007. RESULTS: The series comprised 250 patients, with 232 RYGBPs and 18 BPDs performed. The mean BMI was 46 +/- 4. Only a single case of gastrointestinal hemorrhage (0.4%) was recorded, caused by a marginal ulcer in the early postoperative period (day 6). In the late postoperative period, there were two cases of ulcer (0.8%), one complicated by hemorrhage, the other by perforation. There was no anastomotic leak. One patient (0.4%) required reintervention after 48 h because of thermal perforation of the gastric pouch. There were 11 cases of stenosis (4.4%) requiring radiologically or endoscopically guided dilatation, none in the BPD patients. Mean anastomosis time was 40 +/- 15 min. No cases of mortality or abscess, abdominal sepsis, or thromboembolism were recorded. Mean hospital stay was 5.1 +/- 2.4 days. CONCLUSIONS: Laparoscopic hand-sewn anastomoses are safe and reproducible by surgeons experienced in internal suturing and knot-tying. The technique lengthens operating time, but constant training develops the surgeon's skills, significantly shortening operating time.

Introduction. Laparoscopic surgery offers an alternative diagnostic technique in multiple diseases requiring biopsy of non-digestive intra-abdominal masses in which image-guided biopsy cannot be performed. Laparoscopic biopsy aims to reduce the surgical aggression and complications associated with laparotomy and favors the early treatment of malignancies. Patients and method. We performed a retrospective descriptive study of our results in a series of patients in our hospital with intra-abdominal masses of unknown etiology who underwent laparoscopic surgery between January 2001 and April 2006. None of the patients were candidates for image-guided percutaneous biopsy. Results. We carried out 23 biopsies: 8 retroperitoneal (34.7%), 5 mesenteric (21.7%), 5 hepatic, 4 pelvic, and 1 in the iliac chain, as well as 5 complementary biopsies. In all patients, sufficient material for histologic diagnosis was obtained. The mean operating time was 71 minutes. Length of hospital stay was less than 24 hours in 61% of the patients. The median length of hospital stay was 1.5 days. Conclusions. The laparoscopic approach allows complete visualization and examination of the entire peritoneal cavity. Laparoscopic biopsy is a safe and effective procedure with excellent patient recovery and allows early definitive treatment (AU)
