Endometriosis como causa de obstrucción intestinal tratada por vía laparoscópica / Endometriosis as a cause of bowel obstruction treated with laparoscopy

La endometriosis intestinal es una causa poco frecuente de abdomen agudo que debe incluirse en el diagnóstico diferencial de la obstrucción intestinal en mujeres fértiles con antecedentes de episodios repetidos de dolor abdominal. Presentamos un caso clínico de dicha patología, diagnosticada mediante laparoscopia exploradora ante un cuadro de obstrucción intestinal sin respuesta al tratamiento conservador (AU)

Intestinal endometriosis is a very uncommon cause of acute abdomen that must be included in the differential diagnosis of small bowel obstruction in young fertile women with a history of recurrent abdominal pain. We present a case of this disease diagnosed by exploratory laparoscopy in a patient with bowel obstruction and no response to conservative treatment (AU)

Biliary cystadenoma.

The diagnosis of cystadenoma is rare, even more so when located in the extrahepatic bile duct. Unspecific clinical signs may lead this pathology to be misdiagnosed. The need for pathological anatomy in order to distinguish cystadenomas from simple biliary cysts is crucial. The most usual treatment nowadays is resection of the bile duct, together with cholecystectomy and Roux-en-Y reconstruction.

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.
