RESUMEN
AIM: Single port laparoscopic colorectal surgery (SPLC), performed through a single incision of ≤ 3 cm, has been shown to be feasible. This study aimed to assess its safety and efficacy when used as the method of choice for right hemicolectomy. METHOD: A prospective study was carried out of patients undergoing right hemicolectomy using a single port laparoscopic technique. They were compared with a historical series of patients undergoing right hemicolectomy using a multiport laparoscopic technique. Between December 2009 and September 2010, single port surgery replaced conventional laparoscopic colorectal surgery (LCS) for radical medial to lateral right hemicolectomy performed by a single surgeon. Histology, length of hospital stay, complications, conversions and readmissions were recorded. RESULTS: Fourteen patients were treated using single port laparoscopic surgery (SPLC): 10 for carcinoma (Dukes A1, B6, C3) and four for Crohn's disease. Twelve patients were treated using multiport laparoscopic colorectal surgery (LCS): eight for carcinoma (Dukes B4, C3, Carcinoid 1), three for Crohn's disease and one for adenoma. The median (interquartile range) operative time for the SPLC group was 120 (90-135) min and for the LCS group was 135 (116-150) min. The median (interquartile range) length of hospital stay was 3.5 (2.0-5.0) days for the SPLC group and for the LCS group was 4.0 (3.8-7.0) days. The median (interquartile range) number of lymph nodes removed for SPLC patients was 14.5 (9.8-19.5) and for the LCS patients was 14.5 (13.0-19.5). There were no conversions, no complications and no readmissions in either group. CONCLUSION: These data confirm the feasibility of the technique. Furthermore they suggest that it is safe and efficacious.

BACKGROUND: Dietary questionnaire studies have suggested that patients with oesophageal adenocarcinoma are deficient in antioxidants. It is not known whether the same holds true for patients with the precursor lesion, Barrett's oesophagus. AIMS: To evaluate the hypothesis that patients with Barrett's oesophagus are deficient in antioxidants compared with patients without evidence of Barrett's oesophagus. PATIENTS AND METHODS: Plasma antioxidant profiles (copper, selenium, zinc; vitamins A, C, and E; carotenoids) were determined for patients with Barrett's oesophagus (n = 36), patients with erosive oesophagitis (n = 32), and patient controls (n = 35). RESULTS: Patients with Barrett's oesophagus had significantly lower plasma concentrations of selenium, vitamin C, beta cryptoxanthine, and xanthophyll compared with the other groups. CONCLUSIONS: This study confirms the hypothesis that patients with Barrett's oesophagus are deficient in certain antioxidants.

AIMS: To study the frequency with which unresectable disease was identified on pre-operative staging investigations in patients with oesophago-gastric carcinoma, and to audit whether a staging protocol had reduced the rate of exploratory surgery. METHODS: Ninety-eight patients with oesophageal carcinoma, 89 patients with adenocarcinoma of the gastro-oesophageal junction (GOJ) and 68 patients with gastric carcinoma were staged according to a protocol of computerised tomography, laparoscopy and endoscopic ultrasound. RESULTS: The frequency with which each investigation identified unresectable disease was as follows: (a) computerised tomography-oesophagus 12/67, GOJ 13/58, stomach 10/60; (b) laparoscopy-oesophagus 3/22, GOJ 5/45, stomach 8/23; and (c) endoscopic ultrasound-oesophagus 15/55, GOJ 3/30. By tumour location, rates of exploratory surgery were 1/18 for the oesophagus, 12/35 for the GOJ and 4/42 for the stomach. All of the staging failures in patients with GOJ carcinomas related to posterior tumour extension into the lesser sac. CONCLUSIONS: Staging investigations precluded resection in one-third of patients, the greatest yield being for laparoscopy in gastric carcinoma. In spite of this, 18% of patients undergoing surgical intervention underwent exploratory surgery alone, notably patients with GOJ carcinoma.

We report a case of excision of a vagal paraganglionoma resulting in Horner's syndrome. The case was initially misdiagnosed as a carotid body tumour and demonstrates the need for adequate preoperative imaging and patient counselling for likely complications of surgery.
