Laparoscopic repair of postoperative perineal hernia using a two-mesh technique.

AIM: Perineal herniation following abdomino-perineal excision of the rectum (APER) can be debilitating. Repair options include a transabdominal (laparoscopic or open), perineal or a combined approach, but there is no consensus on the optimal technique. We describe a novel laparoscopic two-mesh technique and short- to medium-term outcomes. METHOD: Six patients underwent this operation between 2008 and 2014. Patients were positioned in a modified Lloyd-Davies position, allowing perineal access, and steep Trendelenburg to aid displacement of small bowel from the pelvis. A polypropylene mesh was shaped, placed over the hernial defect, tacked postero-laterally and sutured antero-laterally to reconstitute the pelvic diaphragm. A second larger mesh (composite) was placed over the first supporting mesh and secured with tacks and sutures, overlapping the hernial defect, preventing small bowel contact with the mesh. RESULTS: The median time from the index operation to presentation of the hernia was 5 months. One patient with dense small bowel adhesions from the primary repair had a combined laparoscopic and perineal approach. The median operating time was 141 min and median length of stay was 3 days. There were no intra-operative complications and no recurrences over a follow-up of 1-76 months. CONCLUSION: We describe a novel laparoscopic technique for perineal hernia repair following APER with a low recurrence rate in the intermediate term.

Leucocyte count and oral temperature are a useful guide to selecting women with right iliac fossa pain for diagnostic laparoscopy.

INTRODUCTION: In women, negative appendicectomy rates can be as high as 34%. A 5-fold reduction is possible with diagnostic laparoscopy. A selective policy is favoured as indiscriminate use may increase postoperative morbidity. Scoring systems are helpful but not used widely due to their complexity. The value of leucocyte count and temperature in selecting women with right iliac fossa pain for diagnostic laparoscopy is investigated. PATIENTS AND METHODS: Over a 12-month period, admission leucocyte count and temperature data were obtained from women undergoing appendicectomy. Cohorts were sub-categorised by age (< 20, 21-40 and > 40 years) and the proportion of negative (normal appendix) and positive (inflamed, gangrenous or perforated appendix) appendicectomies compared. RESULTS: In 100 women, 11% had leucocyte counts and temperature > or = 11 x 10(9)/l and 38 degrees C, respectively; all had appendicitis. In 50%, leucocyte counts and temperature were > or = 11 x 10(9)/l and < 38 degrees C; negative appendicectomies occurred in 13.8% < 20 years, 10% > 40 years (P < 0.01) and 27.3% aged 21-40 years (P = 0.086). In 39%, the negative appendicectomy rate was > or = 36.8% when leucocyte count and temperature were < 11 x 10(9)/l and 38 degrees C (P = 0.1). CONCLUSION: Diagnostic laparoscopy should be considered in all women when leucocyte counts and temperature are > or = 11 x 10(9)/l and 38 degrees C and for females aged 21-40 years when these values are > or = 11 x 10(9)/l and < 38 degrees C.

A rare complication following laparoscopic TEP repair: case report and discussion of the literature.

Transabdominal pre-peritoneal and totally extra-preperitoneal (TEP) are common laparoscopic techniques used to repair inguinal hernias. With better equipment and techniques for creation of pneumoperitoneum serious complications are now infrequent. However, complications from these techniques that are beyond the control of the surgeon do occur. This report details a rare complication related to infection. It is the first such documented complication of TEP hernia repair. There follows a short literature review of rare complications of laparoscopic hernia repair. Surgeons should familiarize themselves with these potential pitfalls for a number of reasons including, counseling when obtaining consent and heightened awareness for infrequent complications during postoperative follow-up.

Assessment of preoperative fluid depletion using bioimpedance analysis.

BACKGROUND: Fluid depletion during the perioperative period is associated with poorer outcome. Non-invasive measurement of total body water by bioimpedance may enable preoperative fluid depletion and its influence on perioperative outcome to be assessed. METHODS: Weight and foot bioimpedance were recorded under standardized conditions in patients undergoing bowel preparation (n=43) or day surgery (n=44). Fifteen volunteers also followed standard nil-by-mouth instructions on two separate occasions to assess the variabilities of weight and bioimpedance over time. RESULTS: Body weight fell by 1.27 kg (95% CI 1.03-1.50 kg; P<0.0001) and foot bioimpedance increased by 51 ohm after bowel preparation (95% CI 36-66; P<0.0001). Weight change after the nil-by-mouth period in day-surgery patients (mean -0.22 kg, 95% CI -0.05 to -0.47 kg; P=0.07) correlated (r=-0.46; P=0.005) with an increase in bioimpedance (16 ohms, 95% CI 5-27 ohms; P=0.01). No difference between two separate bioimpedance measurements was seen in the volunteer group. CONCLUSIONS: Further work is warranted to determine if bioimpedance changes may serve as a useful indicator of perioperative fluid depletion.

A simple technique for the retention of a subcuticular suture.

The retention of a subcuticular stitch using absorbable suture has been performed using a variety of methods. These techniques may be difficult to master by surgeons new to the skill and have been associated with problems such as "dog ears" and a bulky knot that becomes difficult to bury. The latter can also be responsible for wound gapping especially of small wounds. The procedure described here provides a secure mechanism for retaining the subcuticular suture with minimal bulk to the knot. It is easy to master, does not produce wound gaping and is suitable for all wound sizes.

Abdominal tuberculosis: the problem of diagnostic delay.

Abdominal tuberculosis can be difficult to diagnose. In order to minimize diagnostic delay, an audit study showed that the Mantoux test and/or culture of ascitic fluid did not reveal tuberculosis immediately. Laparoscopy/laparotomy with Ziel-Nielson staining and culture of tissue biopsy always confirmed the diagnosis. It is suggested that biopsy should be the first line in investigating patients suspected of having abdominal tuberculosis.
