Injection port and connecting tube complications after laparoscopic adjustable gastric banding.

Background: Port-site and connecting tube complications are usually considered minor problems in the follow-up of obese patients submitted to laparoscopic adjustable gastric banding (LAGB), but the incidence reported in literature ranges from 4.3% to 24%. These complications are mainly because of the mechanical stress of the port and the tube; therefore, their incidence might be time dependent and probably increase during the follow-up.

Stapled transanal rectal resection in solitary rectal ulcer associated with prolapse of the rectum: a prospective study.

Purpose: At present, none of the conventional surgical treatments of solitary rectal ulcer associated with internal rectal prolapse seems to be satisfactory because of the high incidence of recurrence. The stapled transanal rectal resection has been demonstrated to successfully cure patients with internal rectal prolapse associated with rectocele, or prolapsed hemorrhoids. This prospective study was designed to evaluate the short-term and long-term results of stapled transanal rectal resection in patients affected by solitary rectal ulcer associated with internal rectal prolapse and nonresponders to biofeedback therapy.

Concurrent band and tube migration following acute pancreatitis.

A 52-year-old woman developed an acute pancreatitis 7 years after gastric banding for morbid obesity. The patient presented a stable weight loss. Three months before, a radiological band calibration showed a normal position of the band.

Does lobectomy for lung cancer in patients with chronic obstructive pulmonary disease affect lung function? A multicenter national study.

Objective: The purpose of this study was to evaluate the effect of lobectomy on pulmonary function in patients with chronic obstructive pulmonary disease.

Methods: One hundred thirty-seven patients were analyzed; 49 had normal pulmonary function tests, and 88 had chronic obstructive pulmonary disease. Different functional parameter groups were identified: obstructive (forced expiratory volume in 1 second [FEV1], forced expiratory volume in 1 second/forced vital capacity [FEV1/FVC], and chronic obstructive pulmonary disease index), hyperinflation (residual volume and functional residual capacity), and diffusion (transfer factor of the lung for carbon monoxide).
