Comparison of closed and open methods of pneumoperitonium in laparoscopic cholecystectomy

Pneumoperitonium is the first step in laparoscopic surgery including cholecystectomy. Two commonly used methods to create pneumoperitonium are closed and open technique. Both have advantages and disadvantages. The current study was designed to compare these two techniques in terms of safety and time required to complete the procedure. This was a randomized controlled prospective study conducted at Department of Surgery, Ayub Hospital Complex Abbottabad, from 1[st] June 2007 to 31[st] May 2008. Randomization was done into two groups randomly using sealed envelopes containing the questionnaire. Seventy envelopes were kept in the cupboard, containing 35 proformas for group A and 35 for group B. An envelope was randomly fetched and opened upon selection of the patient after taking the informed consent. Pneumoperitonium was created by closed technique in group A, and by open technique in group B. Time required for successful pneumoperitonium was calculated in each group. Failure to induce pneumoperitonium was determined for each technique. Time required to close the wounds at completion, total operating time and injuries sustained during induction of pneumoperitonium were compared in both techniques. Out of the total 70 patients included in study, 35 were in group A and 35 in group B. Mean time required for successful pneumo'peritonium was 9.17 minutes in group A and 8.11 minutes in group B. Total operating time ranged from 55 minutes to 130 minutes in group A and from 45 minutes to 110 minutes in group B. Mean of total operating time was 78.34 and 67 minutes in group A and B respectively. Mean time needed to close the wound was 9.88 minutes in group A and 4.97 minutes in group B. Failure of technique was noted in three patients in group A while no failure was experienced in group B. In two cases in group A minor complications during creation of pneumoperitonium were observed while in group B no complication occurred. No patient died in the study. We concluded from this study that open technique of pneumoperitonium was, less time consuming and safer than the closed technique

Carcinoma of prostate in clinically benign enlarged gland

Carcinoma of the prostate is one of the common tumours of old age in men. This cross sectional study was conducted to detect carcinoma of prostate in clinically benign enlarged gland and to evaluate the efficacy of Digital rectal Examination in detection of prostatic cancer in patients presented at Khyber Teaching Hospital, Peshawar from July 1998 to July 1999. Patients presenting with lower urinary tract symptoms over the age of 50 years were evaluated on English version of International Prostate Symptoms Score [IPSS], clinically examined and post-voiding residual urine determined on abdominal sonography. The selection criteria were; Severe IPSS, absence of signs of malignancy on Digital Rectal Examination [DRE] and post-voiding residual urine more than 100 ml. Thus a total 100 patients were selected for further study. Four ml blood was taken to assess Prostate Specific Antigen [PSA] level pre-operatively. All these patients underwent either transvesical prostatectomy or transurethral resection of prostate [TURP] and enucleated prostatic tissues were sent to histopathology. Eighty-five percent patients had PSA level up to 10 [eta]g/ml. PSA level of 15 [15%] patients were above 10n gm/ml out of which 13 [13%] patients were having PSA in range of 11-12 [eta]g/ml and two [2%] had PSA level between 20-25 [eta]g/ml. Histopathology report of 2% patients turned out as adenocarcinoma of the prostate. Out of 100 patients who were having clinically benign DRE findings, 2 turned out as Carcinoma of the prostate histologically
