Colonoscopic perforation: useful parameters for early diagnosis and conservative treatment.

Objective: The purpose of this study is to determine useful parameters for the early diagnosis of colonoscopic perforation and to select those who would require surgical treatment.

Methods: We retrospectively reviewed the demographics, clinical and colonoscopic data, diagnostic-surgical interval, operative findings, complications, and hospital stay of patients who developed postcolonoscopy iatrogenic colonic perforation between January 2002 and December 2008.

Results: A retrospective multicentric study of patients diagnosed of colonoscopic perforation was performed.

Ligasure versus diathermy hemorrhoidectomy under spinal anesthesia or pudendal block with ropivacaine: a randomized prospective clinical study with 1-year follow-up.

Purpose: We evaluate the safety and efficacy of a spinal anesthesia with lidocaine versus a local anesthesia of pudendal block with ropivacaine combined with intravenous sedation in the hemorrhoidectomy procedure and also we compared the short- and long-term efficacy of conventional diathermy versus Ligasure diathermy hemorrhoidectomy.

Methods: Seventy-four patients of grade III or IV hemorrhoids were randomized to conventional diathermy hemorrhoidectomy under spinal (n = 19) or local anesthesia (n = 18) and Ligasure diathermy hemorrhoidectomy under spinal (n = 17) or local anesthesia (n = 20). Time of follow-up was 12 months.

[Perforated duodenal diverticulum].

Diverticular disease of the duodenum is uncommon. Perforation is the least frequent complication. Diagnosis and treatment are not well defined as the presentation and symptomatology are nonspecific.

Intramural hematoma of the cecum: report of two cases.

Intramural hematoma of the cecum is a rare complication of blunt abdominal trauma. We report two patients who presented with cecal hematoma after a fall and a traffic accident, respectively. Diagnosis was by abdominal computed tomographic scan.

[Central venous catheter location by endocavitary ECG: an alternative to chest radiography].

Background: The location of a central venous catheter is checked with a chest radiograph. Right endocavitary electrocardiography (ECG), a technique in which the catheter is connected to the ECG recorder wire to record ECG in DII, might be an alternate method to check the position of the catheter. When the catheter enters the right atrium, there is a large increase in the amplitude of P wave.

[Efficacy of the ilioinguinal and iliohypogastric block in the treatment of the postoperative pain of inguinal herniorrhaphy].

Introduction: The ileoinguinal-ileohypogastric block (IHB) improves pain control in inguinal hernioplasty.

Objective: To determine the efficacy of the IHB on the treatment of postoperative pain in inguinal herniorrhaphy, and to compare the effect of its use before and after incision for diminishing pain and postponing the first dose of analgesia.

Patients And Methods: Sixty-eight patients scheduled for inguinal herniorrhaphy with mesh were enrolled and distributed randomly in 4 groups as follows: 1) IHB before incision using 0.
